Dr. Nadya Kagansky, a specialist in internal medicine and geriatrics. Most of her work has been dedicated to research in geriatric medicine. Among the subfields in geriatrics, studied on metabolic expressions in the elderly, as this subject remains unclear, unknown, and insufficiently researched in geriatrics. Here are some examples of her studies In a study examining the role of increased blood glucose levels during an acute stroke event, was found that the condition worsens when blood sugar values exceed the normal range. In a study on low blood sugar levels in elderly hospitalized patients there was found that a hypoglycemia during hospitalization was a marker for increased mortality three to six months after discharge. A study on the prevalence of fatty liver in elderly individuals over the age of 90 found a higher prevalence of fatty liver among octogenarians compared to the general population. A study on phosphorus depletion in the elderly during hospitalization found a strong association between phosphorus depletion and refeeding syndrome. Many elderly individuals experience a decline in nutritional status due to physiological and social changes, and it is essential to be aware of the possibility of refeeding syndrome. Another study on the nutritional status of hospitalized elderly patients in a geriatric hospital found a high prevalence of nutritional deterioration during hospitalization.
