Personal Statement

I am a physician-scientist and professor whose research interest has focused on transcultural endocrinology, specifically diabetes prevention, cardiovascular risk factors, nutrition, and lifestyle medicine. I am Lown Scholar in the Cardiovascular Global Health Program of the TH Chan School of Public Health; Harvard University since July 2017 and I was hired in the Miami VA Medical Center as a clinical coordinator of the Glycemia Reduction Approaches in Diabetes: A Comparative Effectiveness Study (GRADE) since April 2017 to February 2020. I also have collaborated as an invited facilitator at the Division of Geriatrics and Palliative Medicine, University of Miami Miller School of Medicine. Since March 16, 2020, I am the Director of the Cardiometabolic Health and Lifestyle Unit at LifeDoc Health, Memphis, TN, US

 

My training and main academic appointments. I graduated from medical school (1982-1990) at 24 years (Cum Laude distinction) and, in 1991, I obtained a position at the School of Medicine at Universidad Centroccidental Lisandro Alvarado (UCLA) where I worked as Tenured Professor of Human Physiology for 25 years (1991-2016).  At the UCLA, my teaching responsibilities was focused on physiology of thermoregulation, nutrition, and metabolism, as well as digestive and endocrine physiology. I also taught nutrition and nutritional support, endocrinology, obesity, diabetes in both undergraduate and postgraduate (Internal Medicine, Surgery, Anesthesiology, Gastroenterology) programs of Medicine and Nursing. During this period, after a two-year internal medicine internship (1991-1992), I completed a Master’s degree in nutrition (Graduated with honors, GPA 5/5, 1994-1997) learning nutrition skills both clinic and research laboratory. At the nutritional biochemistry laboratory, I used animal models investigating the effect of diarrhea induced by lactose on vitamins bioavailability in rats using techniques such as atomic absorption spectrophotometry to measure minerals and high-performance liquid chromatography (HPLC) to measure vitamin A, E, beta-carotene. When I came back to teach at the UCLA (1998), along with other colleagues, I organized and founded and then directed the “Multidisciplinary Nutrition Laboratory” within the Physiology Research Unit with funds from a Kellogg’s grant. In this Lab we started research protocols evaluating nutritional status of micronutrients by HPLC in vulnerable populations (children from poor populations) and implementing nutritional supplementation intervention at schools in the poorest sectors. Also, I standardized and applied indirect calorimetry and exercise cardiopulmonary tests with a CPX Med Graphics Corporation ® metabolic chart.

 

Between 1999 and 2002, I did postgraduate training at the UCLA Medical School and General Hospital for the degree of Specialist in Internal Medicine evaluating in my thesis the effect of hospitalization on nutritional status in patients with diabetes. During this period, I filled the gap of lacking nutrition specialists in the hospital and I directed, along with colleagues of Surgery and intensive care, the initiative to start the “metabolic and nutritional support unit” in the main university hospital of the city when I was doing my internal medicine training. This support unit let me the opportunity to develop protocols for nutritional screening, diagnosis and nutritional support including disease-specific formulations and preparation of enteral and parenteral nutrition.

 

My clinical profile includes the building and foundation of a private practice model, named Cardiometabolic Unit 7 (CMU 7), based on the chronic diseases care model mainly cardiometabolic risk factors, endocrinology, diabetes, nutrition, and obesity where I was CEO for 14 years. The CMU 7 was a reference center for diagnosis and treatment of cardiometabolic risk conditions applying a standardized protocol (clinical, nutritional and laboratory evaluation) in all subjects evaluated. In 2015, CMU was in 3rd place in Venezuela among more than 40 diabetes care units and 1st place when the number of patients was divided between the years of operation. During this period, I attended approximately 12,500 patients and more than 35,000 visits or follow-up services in this high-volume clinical/research practice. I defined and adapted with my team all the protocols of intervention in nutrition and other lifestyle components. In the Cardiometabolic Unit, I organized a multidisciplinary team (physicians of different specialties, exercise physiologist, psychologist, nutritionist, nurses, and a statistician) with pertinent facilities including gym, clinical laboratory, body composition (bioimpedance), sleep apnea laboratory, and indirect calorimetry using a Cardiocoach (Korr ®). The assessment included: clinical, physical activity, coronary heart disease (Globorisk) and diabetes (FINDRISC) risk predictors, anthropometry (weight, height, waist circumference, and skinfolds), body composition (bioimpedance), dietary habits (24 h recall), abdominal ultrasound and biochemical data (fasting glycemia, 75 g oral glucose tolerance test, fasting insulin, total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides, uric acid, SGPT, SGOT, TSH, FT4, hsCRP, and hematologic indices). The standard intervention included: nutritional counseling, exercise supervised by a physical trainer, and pharmacotherapy guided by current Clinical Practice Guidelines. Recently, I was invited to write two chapters for a lifestyle medicine book on transcultural lifestyle medicine that will provide the basis to include the transcultural elements in the model of chronic diseases for the evaluation and treatment of patients with chronic conditions.

Other of my academic appointments have been Visiting professor at the Physiology and Biochemistry Departments of the University of Panamá Faculty of Medicine (2015-2017) (Dr. Enrique Mendoza, Dean of Medicine, supervisor). Here, I contribute with the organization and foundation of the Exercise Physiology laboratory using a Quark RMR, Cosmed®; Fellow of the Postgraduate Diabetes Course at the University of St Andrews School of Medicine, United Kingdom (2013) (Dr. Hugh Mac Dougall and Dr. Ian W. Campbell, supervisors); Visiting Researcher at the Division of Endocrinology of the University of Tennessee Health Science Center and Life DOC, Memphis USA (2006) (Dr. Pedro Velasquez, supervisor) producing 3 high-quality publications; and Visiting Physician at the Department of Medicine and Pharmacology of Mayo Clinic, Rochester, USA (1998) (Dr. Andre Terzic, supervisor).

My productive research has spanned more than 25 years with a wide scope that covers mainly endocrinology disciplines: diabetes, obesity, nutrition, cardiovascular risk factors, lifestyle medicine, with high emphasis in transcultural components. This has produced 119 publications including 63 original articles and reviews by invitation in peer review journals (17 as first author, 12 as last author and 33 indexed in PubMed); 56 refereed abstracts, posters, and oral communications; and 1 book chapter (3 new book chapters are in press).  My H index is 17 (i10-index 21) by 2020 and my publications have received 8530 citations with the highest productivity since 2014. I am also guest editor of the Venezuelan Society of Endocrinology and Metabolism Journal and reviewer for more at least 10 scientific peer-reviewed journals, including Welcome open access, Public Health Nutrition, British Journal of Nutrition, Therapeutic Advances in Endocrinology and Metabolism, PlosOne, Primary Care Diabetes, International Journal of Clinical Practice, Journal of Immigrant and Minority Health, Journal of Diabetes Research, and Investigacion Clinica (reviewer activity registered in Publons). I have co-authored at least 10 articles as network member of the Non-Communicable Diseases-RisC (NCD) Risk factors collaboration group and I belong to the America Working Group. I have mentored at least 10 graduate students of Internal Medicine, Surgery, Pediatrics, MS in education at the UCLA, 1 MPH candidate and 1 PhD candidate at Harvard School of Public Health, 1 medical student (Columbia University), 1 student of Information Sciences (Dartmouth College), and several students and young professionals in co-authored publications.  

It is known of all the devastating consequences of diabetes and obesity in Latin America and the world, largely driven by the increased risk of cardiovascular disease. The major focus of my research has been: 1.- defining risk factors for diabetes and cardiovascular risk factors and its relationship with social determinants of health, 2.- identifying anthropometric and risk scores cut-offs and individual metabolic phenotypes, and 3.- transculturalizing and implementing diabetes and cardiovascular prevention and lifestyle medicine strategies, including healthy eating patterns.

Venezuela had no data on cardiovascular risk factors and the official statistics came from the morbidity obtained in the health centers. Therefore, to fill this gap and to reach the first research objective, I designed as Principal Investigator and, along with my research team, developed the first sub-national (Venezuelan Metabolic Syndrome, Obesity and Lifestyle Study VEMSOLS, 2011-2015) and the first national study (Venezuelan Cardiometabolic Health Study EVESCAM, 2014-2017) evaluating cardiometabolic risk factors in Venezuela (funded by Novartis grant).   Currently, in the next step, we are doing the follow-up of the EVESCAM cohort to characterize the impact of the worldwide-known current humanitarian crisis on the cardiometabolic health in Venezuela for which I obtained a grant from Harvard University. I presented the preliminary results of the study in Harvard TH Chan School of Public Health (July 2019) and in the First Lown Scholar Colloquium Tanzania (October 2019). Also, we submitted in Harvard Lown Program a proposal of implementation of a community-based culturally adapted diabetes prevention program in Venezuela. After lectures that I gave in Chile and Colombia, I am setting up a team of leaders in Latin America to expand the cultural adaptations of this intervention in Argentina, Chile, Colombia, and Ecuador. Also, we are planning to study the nutritional consequences of the current Venezuelan crisis with a joint Grant with the Nutrition Department at Harvard.

Our second and third research goals are included in the transcultural endocrinology field that I am developing. Transculturalization is a relatively new term and transcultural medicine is today one of the most relevant elements for the improvement of all health care levels, since it is focused on the optimization of therapeutic management and decision making according to each culture based on the evidence obtained by regional and global studies to increase the adherence and effectiveness of interventions.

Along with my team, I have emphasized the need to transculturize and adapt interventions to the context in which they will be implemented contributing in the development of a transcultural endocrinology platform for implementation on domestic and global scales. My contributions include diabetes risk detection strategies (Finnish Diabetes Risk Score, FINDRISC in Latin America), diabetes prevention interventions (Diabetes Prevention Program in Venezuela), new paradigms on obesity and diabetes diagnosis and management (American Association of Clinical Endocrinologist, ACE/ACE Framework), obesity anthropometric cutoffs medical nutritional therapy interventions for diabetes (Transcultural Diabetes nutrition algorithm, tDNA), healthy eating patterns (Mediterranean diet adaptation to Venezuelan population), and the development of guidelines, recommendations, algorithms along with colleagues from national and international scientific societies.

Throughout my career, I have been driven by the desire to provide solutions to our population and patients to decrease the prevalence and consequences of these devastating cardiometabolic conditions. Recently in October 2019, in Tanzania, Harvard University awarded me the John C. Bogle Award that recognizes scientists who propose “A simple solution to a Complex problem” by the proposal of connecting Venezuelan Migrants in need of Medical Care with Providers via telehealth. I have received a total of 23 awards and recognitions.

I have been fortunate to work and built a research network with eminent colleagues in the field who have co-authored publications or projects. This network includes scientist from in USA (Harvard University, Boston; University of Miami, Miami; VA Medical Center, Miami; Mount Sinai, New York: Mayo Clinic, Rochester; Czech Republic (International Clinical Research Center, St Anne’s University Hospital), GREEC, Birmingham; University of Tennessee, Memphis; University of California, San Diego), Europe (Spain), Asia (Lebanon, Iran), Latin America (Venezuela, Brazil, Ecuador, Peru, Argentina, Colombia), and also medical students and young doctors whose framework we have characterized and named Pyramid of Researchers. We have characterized this framework as a stepwise approach to improve scientific productivity. I am planning to continue my research working with this superb group of scientists to decrease the burden of these common diseases and risk factors.  I also have contributed in several scientific organizations to which I have belonged: Latin America Diabetes Association, Venezuelan Society of Endocrinology and Metabolism, Venezuelan Society of Internal Medicine, and Venezuelan Association for the Study of Obesity (Past-President 2012-2014)

In conclusion, the impact of the above research and clinical activities, my academic teaching activity in several universities, my experience in basic sciences, clinic and public health, coupled with my leadership roles has strong local, national, and international impact in the fields of transcultural endocrinology, nutrition, and public health.
