instruction:
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.
question:
Context: To investigate whether intracavitary physiotherapy is superior to endometrial scratching in patients with recurrent implantation failure (RIF) after in vitro fertilization/intracytoplasmic sperm injection- embryo transfer (IVF/ICSI-ET) cycles.', 'According to the inclusion criteria defined by our hospital, 63 patients with RIF were included in the retrospective study. 20 patients who received intracavitary physiotherapy were classified into Group A, 8 patients with both intracavitary physiotherapy and endometrial scratching were into Group B, and 35 patients who underwent endometrial scratching were into Group C. The primary outcome measures were implantation and clinical pregnancy rates. The secondary outcome measure was pregnancy outcome.', 'There were no statistical differences in implantation and clinical pregnancy rates between Groups A and C (29.41 vs 35.59 %, 45.00 vs 48.57 % respectively, P > 0.05), Groups B and C (36.36 vs 35.59 %, 50.00 vs 48.57 % respectively, P > 0.05). In addition, no statistical differences were discovered in pregnancy outcomes between Groups A and C (P > 0.05), Groups B and C (P > 0.05).\Question: Is intracavitary physiotherapy inferior to endometrial scratching in patients with recurrent implantation failure?
answer:
Intracavitary physiotherapy is not inferior to endometrial scratching on improving implantation and clinical pregnancy rates in patients with RIF after IVF/ICSI cycles.


question:
Context: Patient selection for endovascular revascularization treatment (ERT) in acute ischemic stroke depends on the expected benefit-risk ratio. As rapid revascularization is a major determinant of good functional outcome, we aimed to identify its predictors after ERT.', 'Consecutive stroke patients from a single stroke center with distal internal carotid artery-, proximal middle cerebral artery- or T-occlusions treated with ERT were retrospectively selected. We assessed admission noncontrast computed tomography and computed tomography angiography for thrombus location, thrombus load (clot burden score), and collateral status. Clinical data were extracted from medical charts. Univariate and multivariate regression analyses were performed to identify predictors of revascularization (thrombolysis in cerebral infarction ≥2b) after ERT.', 'A total of 63 patients were identified (median age, 73 years; interquartile range: 62-77; 40 females). Sixteen patients (25.4%) underwent intravenous thrombolysis (ivT) before ERT. Twenty-two patients (34.9%) had additional intra-arterial application of recombinant tissue plasminogen activator. The overall recanalization rate was 66.7%, and 9.5% had symptomatic intracranial bleeding. In-hospital mortality was 15%, and 30% reached good functional outcome at discharge. In the univariate analysis, preceding ivT and the number of passes for thrombectomy (dichotomized ≤2 versus >2) were associated with recanalization. There was a trend for number of thrombectomy passes (as continuous variable) and multimodal ERT. In the multivariate regression analysis, ivT prior to ERT and passes of thrombectomy were identified as independent predictors for recanalization.\Question: Does intravenous Thrombolysis and pass of Thrombectomy as Predictors for Endovascular Revascularization in Ischemic Stroke?
answer:
ivT and lower passes of thrombectomy are associated with recanalization after ERT for ischemic stroke with proximal vessel occlusions.


question:
Context: The differential intestinal metabolism of the soy isoflavones is likely to influence the ability of soy to prevent prostate cancer. While daidzein, genistein, and equol have direct antiproliferative effects on prostatic epithelial cells in vitro, there are no such data for the isoflavone glycitein, or seven metabolites: O-desmethylangolensin (ODMA), 6-hydroxyODMA (6H-ODMA), dihydrodaidzein (DHD), cis-4-hydroxyequol (C4HE), 3'-hydroxydaidzein (3HD), 6-hydroxydaidzein (6HD), and 8-hydroxydaidzein (8HD). In the current study, the in vitro activities of these compounds were elucidated, and the active ranges of concentrations were compared to that found in Caucasian prostatic fluid (PF) and plasma samples.", 'The effects of isoflavonoids on cell growth, cell cycle distribution, and apoptosis (active Caspase 3) were examined on benign prostatic epithelial cells (PrEC), and the prostate cancer cell line LNCaP.', 'PF concentrations of genistein, equol, and daidzein (but not ODMA or DHD) were often within the ranges that reduce PrEC growth in vitro. Profound differences in sensitivities were observed with LNCaP. The hydroxydaidzeins, C4HE, and 6H-ODMA had significant inhibitory effects at 10(-5)M on PrEC growth (but not LNCaP). Glycitein had significant effects on both. Reductions in cell growth were typically associated with both changes in cell cycle distribution and Caspase 3 activation. When five isoflavonoids were used in combination at concentrations present in PF samples, synergistic effects were observed.\Question: Are prostatic fluid concentrations of isoflavonoids in soy consumers sufficient to inhibit growth of benign and malignant prostatic epithelial cells in vitro?
answer:

The profound differences in sensitivities of prostatic epithelial cells to these compounds along with their synergistic effects suggest that multiple metabolites in vivo may be optimal for preventing prostate cancer.
