Definition: In this task, you're given a paragraph from the research paper and your task is to generate a suitable title for the research paper based on the given paper. Under 100 words is a good title length.
Input: A 69-year-old male with a past medical history of hypertension, diabetes mellitus, and acute myelogenous leukemia (AML) who underwent allogeneic hematopoietic stem cell transplantation (HSCT) presented with recurrent fever and cough. The patient had undergone allogeneic HSCT from a matched unrelated donor 17 months previously, conditioned by fludarabine, melphalan, and alemtuzumab. His posttransplant course was complicated by graft versus host disease and multiple central venous catheter infections with coagulase-negative Staphylococcus spp., vancomycinresistant Enterococcus, Lactobacillus, and alpha-hemolytic Streptococcus. During his initial course, he also developed a nodular pneumonia, and the subsequent workup included a bronchoscopy that was nondiagnostic. The pneumonia resolved with empiric posaconazole treatment. Sixteen months after the transplant, the patient developed fatigue, low-grade fevers, and cough. Chest x-ray (CXR) showed a new, left lower lobe infiltrate. A sputum culture then grew fluoroquinolone-susceptible Pseudomonas, and the Oncology Service subsequently discharged the patient home on moxifloxacin alone. Three weeks later, he presented again with recurrent cough and fever and was readmitted. A CXR showed a new, right lower lobe infiltrate. The patient had a remote history of symptomatic bradycardia for which he had undergone pacemaker placement. He was a former cigarette smoker (40 pack-years), but he denied any intravenous drug use. He was a retired automobile mechanic and lived at home with his wife and a dog. He had traveled recently to Las Vegas for a short trip to visit casinos. His medications on admission included acyclovir, fluconazole, and dapsone prophylaxis. He previously had an adverse reaction to imipenem, which caused a rash, and to voriconazole, which caused visual hallucinations. On physical examination, he was alert and oriented. His temperature was 100.5 °F, heart rate 86 beats per minute, blood pressure 134/94 mmHg, respiratory rate 20 breaths per minute, and oxygen saturation 90% on ambient air. He had mild bilateral crackles at the lung bases and a well-healed, non-tender, nonerythematous surgical scar at the site of the pacemaker pocket on the anterior chest wall. The remainder of his physical examination was unremarkable. Laboratory values were significant for pancytopenia, with WBC count of 3500/μl, (76% neutrophils, 8% lymphocytes, and 12% monocytes), hemoglobin 11.6 g/dL (normal range, 13.5-17.5 g/ dL), and platelet count of 122,000/μL (normal range, 150,000-450,000/μL).
