Given an abstract, indicate which of the provided candidate titles (Option1 and Option2) best describes it (respond with the text of the title, not option1/2).

Input: Consider Input: Abstract: Postoperative renal function was evaluated in 90 patients operated on for abdominal aortic aneurysms. Forty-four patients were operated on acutely because of impending or actual rupture of the aneurysm. Forty-six patients were operated on electively. The overall mortality rate was 23.7% with a post-operative mortality of 7.8%. Postoperative renal function was evaluated by measurements of the s-creatinine. Impaired renal function was found postoperatively in 45% of the surviving patients. Forty percent of the patients operated on electively had postoperative renal impairment compared with 52% of the patients operated on acutely. The postoperative mortality rate in patients with impaired renal function was 32.4% compared with 8.7% in patients with unchanged renal function. No significant relation between postoperative renal impairment and administration of aminoglycosides, duration of the operation or clamping time of the aorta was found. We found a significant relationship between postoperative renal impairment and episodes of hypotension (p less than 0.01) and the volume of blood transfusions needed (p less than 0.001). 
 Which is the apt title for the abstract? option1: Renal function following aneurysmectomy of the abdominal aorta. option2: Optimal filtering of constant velocity torque data.

Output: Renal function following aneurysmectomy of the abdominal aorta.


Input: Consider Input: Abstract: Administration of nonsteroidal anti-inflammatory drugs (NSAIDs) to patients with chronically impaired renal function has been reported to cause abrupt and sustained reductions in renal plasma flow (RPF), glomerular filtration rate (GFR), and solute and water excretion in association with decreased renal prostanoid production. However, the time course of these acute effects and whether they are sustained during chronic exposure to the NSAIDs are unknown. Accordingly, using standard clearance and balance techniques, we investigated the effects of acute (zero to four hours) and chronic (five days) oral administration of two different NSAIDs on renal function in patients with stable, mild to moderate chronic renal insufficiency (CRI) and in normal subjects. In patients, acute oral administration of ketoprofen (K) and indomethacin (I) resulted in significant decreases in GFR (K: from 36 +/- 3 to 20 +/- 4 ml/min, P = 0.001; I: from 37 +/- 6 to 30 +/- 7 ml/min, P = 0.032; in RPF (K: from 194 +/- 21 to 146 +/- 21 ml/min, P = 0.002; I: from 222 +/- 33 to 147 +/- 18 ml/min, P = 0.016); and in urinary PGE2 excretion (K: from 0.60 +/- 0.25 to 0.08 +/- 0.02 ng/min, P = 0.05; I: from 0.34 +/- 0.06 to 0.18 +/- 0.06 ng/min, P = 0.042). Fractional excretion of sodium chloride and fractional free water clearance (CH2O/CIn) also decreased significantly after both agents. In normal subjects, GFR and RPF were not significantly decreased after acute dosing, whereas urinary PGE2 and fractional excretions of NaCl and free water decreased significantly.(ABSTRACT TRUNCATED AT 250 WORDS) 
 Which is the apt title for the abstract? option1: Effects of acute and chronic dosing of NSAIDs in patients with renal insufficiency. option2: Functional anatomy of the shoulder complex.

Output: Effects of acute and chronic dosing of NSAIDs in patients with renal insufficiency.


Input: Consider Input: Abstract: Episodic arthritis is an uncommon manifestation of cystic fibrosis. We describe the case of a 21-year-old man with cystic fibrosis who suffered from episodic arthritis associated with vasculitic skin lesions. Aetiology is discussed with reference to the possible role of immune complex disease. 
 Which is the apt title for the abstract? option1: Episodic arthritis in cystic fibrosis: a case report. option2: Symposium on thrombosis and antithrombotic therapy--1986.


Output: Episodic arthritis in cystic fibrosis: a case report.
