In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

[Q]: Context: Primary pneumonic plague is a rare but often fatal form of Yersinia pestis infection that results from direct inhalation of bacteria and is potentially transmissible from person to person. We describe a case of primary pneumonic plague in a wildlife biologist who was found deceased in his residence 1 week after conducting a necropsy on a mountain lion.', "To determine cause of death, a postmortem examination was conducted, and friends and colleagues were interviewed. Physical evidence was reviewed, including specimens from the mountain lion and the biologist's medical chart, camera, and computer. Human and animal tissues were submitted for testing. Persons in close contact (within 2 meters) to the biologist after he had developed symptoms were identified and offered chemoprophylaxis.", 'The biologist conducted the necropsy in his garage without the use of personal protective equipment. Three days later, he developed fever and hemoptysis and died approximately 6 days after exposure. Gross examination showed consolidation and hemorrhagic fluid in the lungs; no buboes were noted. Plague was diagnosed presumptively by polymerase chain reaction and confirmed by culture. Tissues from the mountain lion tested positive for Y. pestis, and isolates from the biologist and mountain lion were indistinguishable by pulsed-field gel electrophoresis. Among 49 contacts who received chemoprophylaxis, none developed symptoms consistent with plague.\Question: Do primary pneumonic plague contracted from a mountain lion carcass?
[A]: The biologist likely acquired pneumonic plague through inhalation of aerosols generated during postmortem examination of an infected mountain lion. Enhanced awareness of zoonotic diseases and appropriate use of personal protective equipment are needed for biologists and others who handle wildlife.


[Q]: Context: Interleukin-8 (IL-8), a CXC chemokine that induces the migration and proliferation of endothelial cells and smooth muscle cells, is a potent angiogenic factor that may play a role in atherosclerosis. Previously, IL-8 has been reported in atherosclerotic lesions and circulating macrophages from patients with atherosclerosis. Therefore, we sought to determine whether IL-8 plays a role in mediating angiogenic activity in atherosclerosis.', 'Homogenates from 16 patients undergoing directional coronary atherectomy (DCA) and control samples from the internal mammary artery (IMA) of 7 patients undergoing bypass graft surgery were assessed for IL-8 content by specific ELISA, immunohistochemistry, and in situ hybridization for IL-8 mRNA. The contribution of IL-8 to net angiogenic activity was assessed using the rat cornea micropocket assay and cultured cells. IL-8 expression was significantly elevated in DCA samples compared with IMA samples (1.71+/-0.6 versus 0.05+/-0.03 ng/mg of total protein; P<0.01). Positive immunolocalization of IL-8 was found exclusively in DCA tissue sections, and it correlated with the presence of factor VIII-related antigen. In situ reverse transcriptase polymerase chain reaction revealed the expression of IL-8 mRNA in DCA tissue. Corneal neovascular response, defined by ingrowth of capillary sprouts toward the implant, was markedly positive with DCA pellets, but no constitutive vessel ingrowth was seen with IMA specimens. Neutralizing IL-8 attenuated both the in vivo corneal neovascular response and the in vitro proliferation of cultured cells.\Question: Is iL-8 an angiogenic factor in human coronary atherectomy tissue?
[A]: The results suggest that, in human coronary atherosclerosis, IL-8 is an important mediator of angiogenesis and may contribute to plaque formation via its angiogenic properties.


[Q]: Context: ST-segment resolution (STR) is a well-established and simple tool for assessing the efficacy of reperfusion therapy in myocardial infarction. An incomplete (<50%) STR is a recognized marker of failed thrombolysis and a suitable recruitment criterion for rescue angioplasty.', 'We sought to determine the predictive value of the total absence of STR after thrombolysis in rescue angioplasty (percutaneous coronary intervention [PCI]).', 'Eighty-one consecutive patients who underwent a rescue angioplasty for failed thrombolysis in our institution from 2001 to 2007 were included. Two groups of patients were defined according to their STR extent, 90 minutes after lysis: partial resolution group 1 (10%-50% STR) vs absence of resolution group 2 (<10% STR) and compared in terms of in-hospital and long-term outcomes.', 'Patients of group 2 were more likely to experience hemodynamic deterioration (50% vs 24%; odds ratio [OR] = 3.17; P = .017), to have a Thrombolysis in Myocardial Infarction 0 flow on the culprit artery (62.3% vs 42%; OR = 2.24; P = .045), to have a multivessel disease (66.7% vs 40%; OR = 3; P = .018), and to die during index hospitalization (26.7% vs 6%; OR = 5.69; P = .013) despite statistically similar rates of PCI failure in both groups (10% vs 7%; P = .402) and similar post-PCI STR (72% +/- 18.25% vs 75% +/- 11.62%; P = .36). In multivariate analysis, total absence of STR proved to be an independent predictor of in-hospital mortality (HR = 7.02; P = .032; 95% confidence interval, 1.18-41.58). Long-term major adverse cardiac events occurred more frequently in group 2 (log rank, P = .004) and were (on the Cox regression model) independently predicted by total absence of STR (HR = 6.21; P = .023; 95% confidence interval, 1.28-29.1).\Question: Is total absence of ST-segment resolution after failed thrombolysis correlated with unfavorable short- and long-term outcomes despite successful rescue angioplasty?
[A]:
The STR assessment before rescue PCI proved to be a good and simple means to predict the short- and long-term prognosis in these patients.
