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: To test the hypothesis that core and suggestive features in possible dementia with Lewy bodies (DLB) would vary in their ability to predict an abnormal dopamine transporter scan and therefore a follow-up diagnosis of probable DLB. A further objective was to assess the evolution of core and suggestive features in patients with possible DLB over time depending on the (123)I-FP-CIT SPECT scan result.', 'A total of 187 patients with possible DLB (dementia plus one core or one suggestive feature) were randomized to have dopamine transporter imaging or to follow-up without scan. DLB features were compared at baseline and at 6-month follow-up according to imaging results and follow-up diagnosis.', "For the whole cohort, the baseline frequency of parkinsonism was 30%, fluctuations 29%, visual hallucinations 24%, and REM sleep behavior disorder 17%. Clinician-rated presence of parkinsonism at baseline was significantly (p = 0.001) more frequent and Unified Parkinson's Disease Rating Scale (UPDRS) score at baseline was significantly higher (p = 0.02) in patients with abnormal imaging. There was a significant increase in UPDRS score in the abnormal scan group over time (p < 0.01). There was relatively little evolution of the rest of the DLB features regardless of the imaging result.\Question: Do evolution of clinical features in possible DLB depending on FP-CIT SPECT result?

A: In patients with possible DLB, apart from UPDRS score, there was no difference in the evolution of DLB clinical features over 6 months between cases with normal and abnormal imaging. Only parkinsonism and dopamine transporter imaging helped to differentiate DLB from non-DLB dementia.

Q: Context: The majority of cancer chemotherapy can lead to bone marrow depression, which often affects clinical response as chemotherapy can not be carried out with enough dosage on time. The platelets decrease is one of the problems caused by bone marrow depression. Though the clinical response of hyodermic "IL-11" is affirmed to advance platelets presently, it is limited by expensive price. Other agents that can be taken orally with suitable price and equal authenticity are less reported. The author observed clinical response of platelets decrease adopting traditional Chinese medicine "Sheng Ban Recipe"(SBR).', 'Totally 103 patients with platelets decrease after chemotherapy from July 1994 to Jannary 2002. They were randomly divided into two groups: SBR plus common treatment group and common treatment alone group. The previous group take 1 package SBR for twice drink per day. Common treatment group give common therapy only. The follow-up period is 2 weeks.', 'Among the 55 cases in SBR group, noticeable efficiency 20%, efficiency 50.9%, total efficiency 70.9%, which is evidently superior to common group.\Question: Do [ Observation of clinical response of `` sheng ban recipe '' for platelets decrease after chemotherapy ]?

A: "Sheng Ban Recipe" can effectively treat thrombocytopenia after chemotherapy, which helps to reduce the necessary of intravenous drip of platelets and the risk of hemorrhage.

Q: Context: The 6-min walk test (6MWT) has prognostic value in various pulmonary disorders including idiopathic pulmonary fibrosis (IPF). We determined the individual prognostic accuracy of distance walked and oxygen saturation during the 6MWT in patients with IPF. We defined a new composite index, the distance-saturation product (DSP), which is the product of distance walked and lowest oxygen saturation during the 6-min walk test. We compared the performance of the DSP to the individual 6MWT parameters in predicting mortality.', 'We evaluated pulmonary function tests, 6-min walk parameters and the DSP between survivors and non-survivors. The ability of each measure to discriminate outcomes was determined by receiver operator curves.', '81 patients (48 survivors, 33 non-survivors) were included. Pulmonary function tests were similar and did not correlate with survival. Desaturation was greater (89.4% versus 83.7%, P<0.001) and distance walked was lower (406.9 versus 181.3m, P = 0.005) in non-survivors. The DSP was significantly lower among non-survivors (364.8 versus 153.5m%, P < 0.001) and predicted mortality more accurately than either individual 6MWT component (P = 0.035 versus desaturation, P=0.040 versus distance). A DSP <200 m% was associated with a seven-fold greater risk of 12-month mortality and an 18.0% shorter median survival compared with a DSP > 200 m% (P < 0.001).\Question: Does the distance-saturation product predict mortality in idiopathic pulmonary fibrosis?

A:
Each component of the 6-min walk independently predicted mortality in IPF with greater accuracy than spirometry. However, a composite of both parameters, the DSP, provides slightly greater accuracy and represents a novel measure for assessing survival in patients with IPF.
