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).

Example Input: Abstract: To achieve adequate arterial BP, adequate capillary filling time, and adequate peripheral pulses, hypotensive newborn infants often require higher doses of dopamine that reportedly reduce urine output in adults. Whether these larger doses of dopamine also reduce urine output in newborns is not known. Therefore, we determined the effects of administering high-dose dopamine (more than 20 micrograms/kg X min) on the urine output of 15 newborn infants. Five infants were studied prospectively and ten retrospectively. In the prospective study, urine output was determined as the dose of dopamine was increased; in the retrospective study, urine output was determined as the infants were being weaned from high doses of dopamine. Both data sets demonstrate that administering high-dosage dopamine does not reduce the urine output of sick newborn infants. Therefore, we conclude that doses of dopamine previously reported to decrease urine output in adults do not do so in sick newborn infants. Consequently, when necessary, high doses of dopamine may be used in sick newborn infants to achieve cardiovascular stability without reducing urine output.
Which is the apt title for the abstract? option1: Effect of high-dose dopamine on urine output in newborn infants. option2: The distribution of multiple sclerosis in the United Kingdom.
Example Output: Effect of high-dose dopamine on urine output in newborn infants.

Example Input: Abstract: The renal effects of carbohydrates (CHO) were studied in two experiments. 1) The effects of CHO-energy restriction was evaluated by comparing uremic growing rats (initial weight: 80 g) fed "ad lib" (L rats) or CHO-restricted (starch and glucose) but receiving identical amounts of all other nutrients (R rats). R rats showed reduced growth, slower increase in plasma creatinine, lower mortality rate, and less histological renal damage than L rats. 2) Two types of CHO restriction, low glucose (R1 rats) or low starch (R2 rats) were compared to "ad lib" feeding (L1 rats) in adult rats (initial weight: 130 g). Growth was identically reduced in R1 and R2 rats. Mean plasma creatinine levels at week four was lower in R1 than in L1 rats. The overall rate mortality was higher for L1 and R2 than in R1 rats (79%, 81%, 53%) but included deaths from other causes than renal failure. Actuarial survival excluding these deaths was 27%, 83% and 10% in L1, R1 and R2 rats, respectively. Diffuse renal lesions were found in 25 of 30 L1, 5 of 15 R1, and 12 of 15 R2 rats (R1 vs. R1 and R2, P less than 0.01). The results show that CHO restriction may preserve the renal parenchyma, and suggest that restriction of "simple" rather than "complex" CHO restriction may be beneficial, a finding which could be of clinical importance if confirmed by further investigations.
Which is the apt title for the abstract? option1: Role of amount and nature of carbohydrates in the course of experimental renal failure. option2: Vaginal discharge. Its causes and cures.
Example Output: Role of amount and nature of carbohydrates in the course of experimental renal failure.

Example Input: Abstract: Thirty legs in nineteen patients, eleven with bilateral and eight with unilateral chronic anterior-compartment syndrome, were treated by fasciotomy. In addition, five of these patients (six legs) had compression of the superficial peroneal nerve: two before and three after fasciotomy. One patient also had lateral compartment syndrome in one leg. The patients who had compression of the superficial peroneal nerve were relieved by partial fasciectomy and fasciotomy of the lateral compartment. In one of these patients, with bilateral nerve compression, both superficial peroneal nerves were anomalous. The patient who had lateral compartment syndrome was relieved by fasciotomy of this compartment. Two patients required a second fasciotomy due to recurrence of the chronic compartment syndrome. At an average length of follow-up of twenty-five months after fasciotomy for anterior compartment syndrome, functional capacity was unlimited or increased in eighteen patients (twenty-eight legs) and was unchanged in one patient (two legs) who had had compression of the superficial peroneal nerve. The intramuscular pressures in the anterior compartment were normal at rest as well as during and after exercise eight months after the original fasciotomy in twenty-eight legs and eight months after the second fasciotomy in two legs.
Which is the apt title for the abstract? option1: Chronic anterior-compartment syndrome of the leg. Results of treatment by fasciotomy. option2: One-stage plastic reconstruction of a totally amputated cancerous penis using a unilateral myocutaneous gracilis flap.
