Given an abstract of a paper, generate a title for this paper such that conveys the key focus of the paper.

Input: Consider Input: Abstract: Enhanced clinical awareness of infective endocarditis, along with improved microbiologic methodology and more aggressive surgical intervention, has favorably influenced the outcome of the disease. The evolving nature of infective endocarditis over the past decade is described, as are the changing epidemiologic factors, microbiologic techniques, and echocardiographic contributions in the clinical management of patients with infective endocarditis.

Output: Infective endocarditis: a challenging disease.

Input: Consider Input: Abstract: Absorption of dietary phosphorus plays a critical role in the development of metabolic bone diseases in patients with chronic renal failure. However, phosphorus absorption is difficult to quantitate in dialysis patients because the dialysis treatments complicate metabolic balance studies. Utilizing a recently developed technique which permits measurement of net absorption of dietary constituents after a single meal, we measured phosphorus absorption in dialysis patients. The following observations were made: A.) Following a meal containing approximately 300 mg phosphorus, mean phosphorus absorption in five hemodialysis patients (with severe vitamin D deficiency) was only slightly less than in matched controls (186 +/- 35 vs. 242 +/- 30). B.) After dialysis patients were treated with 1,25(OH)2-D3, phosphorus absorption increased from 186 +/- 35 to 272 +/- 16 mg (P less than 0.025). C.) The effect of three aluminum containing antacids on phosphorus absorption was studied; each slightly reduced the absorption of phosphorus compared to placebo (P less than 0.01), but there was no significant difference between them. D.) Aluminum hydroxide and calcium carbonate each reduced dietary phosphorus absorption to approximately the same extent. Calcium carbonate ingestion was associated with sharply increased calcium absorption. The absorption of dietary phosphorus is influenced only modestly by 1,25(OH)2-D3 and is inhibited to an equal but only modest degree by various aluminum antacids and by calcium carbonate.

Output: The absorption of dietary phosphorus and calcium in hemodialysis patients.

Input: Consider Input: Abstract: In routine clinical practice and in research interviews like the Diagnostic Interview Schedule (DIS), symptoms attributed to physical illness are excluded from contributing positively toward psychiatric diagnoses. The maximal rate of underdiagnosis which results from this diagnostic rule was determined in 114 patients with diabetes mellitus. When symptoms attributed to diabetes (total = 296, mean = 2.6 per patient) were discounted, 256 diagnoses were made. Eighteen additional diagnoses (a 6.7% increase) were appreciated when these excluded symptoms were considered as psychiatrically significant; however, only two of these new diagnoses were given to patients previously without a psychiatric diagnosis. The authors concluded that the DIS is sensitive in its detection of psychiatric illness in diabetes and perhaps other physical illnesses as well.
Output: Use of the Diagnostic Interview Schedule in patients with diabetes mellitus.
