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: A 4 1/2-month-old, white girl was admitted to the hospital with respiratory distress and persistent polymicrobial bacteremia. Cystic fibrosis associated with malnutrition and a transient defect in peripheral neutrophil chemotaxis was diagnosed. This remarkable combination of presenting features in a patient with cystic fibrosis is the focus of this case report.
Which is the apt title for the abstract? option1: Polymicrobial bacterial sepsis and defective neutrophil chemotaxis in an infant with cystic fibrosis. option2: Short latency somatosensory-evoked potentials in children--Part 3. Findings following head injury.

Output: Polymicrobial bacterial sepsis and defective neutrophil chemotaxis in an infant with cystic fibrosis.

Input: Consider Input: Abstract: The effectiveness and complications of radiation therapy for brain neoplasms are reviewed. While the available data suggest a favorable influence and outcome, randomized studies are needed to further optimize radiation therapy techniques and to integrate new therapeutic modalities.
Which is the apt title for the abstract? option1: Radiation therapy for neoplasms of the brain. option2: False labor.

Output: Radiation therapy for neoplasms of the brain.

Input: Consider Input: Abstract: Thrombospondin with fibrinogen, fibronectin, and von Willebrand factor binds to platelets stimulated with agonists and support platelet adhesive functions. The receptors for the latter three proteins are associated with membrane glycoprotein GPIIb-IIIa. Thrombasthenic platelets deficient in GPIIb-IIIa have been utilized to examine the role of this membrane protein in the interactions of thrombospondin with platelets. Radioiodinated thrombospondin bound to thrombin-stimulated platelets from normal and thrombasthenic donors with a similar affinity and capacity. As monitored with a monoclonal antibody to thrombospondin, the divalent ion-dependent and -independent pathways for the expression of the endogenous pool of thrombospondin on the surface of thrombin-stimulated platelets from normal and thrombasthenic donors were also qualitatively and quantitatively similar. GPIIb-IIIa or ligands associated with GPIIb-IIIa thus are not essential for the binding of thrombospondin to platelets. Therefore, thrombospondin interacts with unique receptors on platelets.
Which is the apt title for the abstract? option1: Identification of a new class of inducible receptors on platelets. Thrombospondin interacts with platelets via a GPIIb-IIIa-independent mechanism. option2: Vacuolar encephalopathy of AIDS [letter]
Output: Identification of a new class of inducible receptors on platelets. Thrombospondin interacts with platelets via a GPIIb-IIIa-independent mechanism.
