| pubmed-article:12092636 | pubmed:abstractText | It is estimated that by the year 2050 one in five Americans will be 65 years or older. This mandates the growing need for clinical and basic research in the field of geriatric medicine to understand age-related maladies. The most prominent abnormality in renal function in the aging population is the inability to handle water, frequently resulting in hypo- or hyperosmolar states, and the associated electrolyte imbalances. During the past decade, thanks to the advent of powerful molecular techniques, rapid strides have been made in the approaches employed to understand and dissect the physiology of renal function in general and the urinary concentration mechanism in particular. Using an integrated approach of clinical observations, experimental model systems, molecular analysis, and functional genomics, a more comprehensive picture of the interplay of physiological systems in the genesis of urinary concentration defect in the elderly is beginning to emerge. Much remains to be deciphered regarding the complex interactions between the role of environment, genetics, diet, pharmacological agents and the general effects of aging on kidney function. The emerging importance of socio-economic and quality of life issues surrounding geriatric medicine encourage public and private support and funding for research in the area of age-related diseases, especially as they are related to the kidney. | lld:pubmed |
