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.

Context: Several Northern Hemisphere Drosera species have been used in the therapy of respiratory tract infections as the traditional medicine Droserae Herba.', 'To determine the anti-inflammatory effects of Drosera species and to investigate a substitute material for Droserae Herba, we examined the effect of extracts of Drosera rotundifolia, Drosera tokaiensis and Drosera spatulata on activated T cell membrane (aTc-m)-induced inflammatory gene expression in HMC-1 human mast cells.', 'Drosera rotundifolia, Drosera spatulata and Drosera tokaiensis were collected in Japan. Herbs were extracted with 80% EtOH, and subsequently applied to OASIS HLB column. HMC-1 cells were treated with each Drosera column-adsorbed fraction for 15min, and subsequently added to aTc-m and incubated for 16h. Inflammatory gene and protein expressions were determined by DNA microarray, RT-PCR and Western blotting.', 'Drosera rotundifolia and Drosera tokaiensis fractions, but not the Drosera spatulata fraction, suppressed inflammatory gene expression induced by aTc-m in HMC-1 cells.\Question: Do drosera rotundifolia and Drosera tokaiensis suppress the activation of HMC-1 human mast cells?
Drosera rotundifolia and Drosera tokaiensis suppressed activation of HMC-1 cells induced by aTc-m. Since the Drosera tokaiensis fraction was more effective than the traditionally used Drosera rotundifolia, Drosera tokaiensis is a likely substitute as a source of Droserae Herba.

Context: Linitis plastica-type gastric carcinoma remains a disease with poor prognosis despite an aggressive surgical approach. Although a prominent pattern of disease failure is peritoneal carcinomatosis, some patients experience rapid disease progression without signs of the peritoneal disease.', 'Clinicopathologic data from 178 patients with linitis plastica-type gastric cancer operated on between 1991 and 2000 were analyzed. Survival stratified by curability of surgery, pN stage, and patterns of failure were evaluated by using the Kaplan-Meier method, and chi(2) test was used to evaluate correlation between the number of metastatic lymph nodes in terms of pN categories and the incidence of various patterns of metastasis and recurrence. Cox regression hazard model was used to identify independent prognostic factors.', 'R0 resection was performed only among 82 patients (46% of those who underwent laparotomy). Node metastasis was frequent with only 22 patients classified as pN0. Peritoneal carcinomatosis was observed in 131 patients and was the commonest pattern of recurrence. Bone metastasis, found in 13 patients, was associated with poor outcome, and its incidence was significantly correlated with the number of metastatic nodes. pT4 status and pN3 status were identified as significant independent prognostic determinants.\Question: Is the number of metastatic lymph nodes a significant risk factor for bone metastasis and poor outcome after surgery for linitis plastica-type gastric carcinoma?
Treatment strategy for the linitis plastica should in general combine surgery with aggressive treatment directed toward peritoneal disease. However, patients with >16 metastatic nodes more often are associated with bone metastasis than those with modest nodal involvement and suffer from poor prognosis.

Context: We designed an assessment and education program which was delivered to patients prior to first outpatient appointment for bariatric surgery. We hypothesised that this program would streamline care and would lead to improved weight loss following bariatric surgery.', 'The program incorporates a structured general practitioners (GP) review, a patient information evening and an on-line learning package. It was introduced in September 2012. Patient flow through the program was recorded. Outcomes of the new program were compared with contemporaneously treated patients who did not undertake the pre-hospital program.', 'All 636 patients on the waiting list for first appointment at the Alfred Health bariatric surgery clinic were invited to participate. There were 400 patients ultimately removed from the waiting list for first appointment. Of the remaining 236 patients, 229 consented to participate in the new program. The mean BMI was 47.8\u2009±\u20099.2. The fail to attend first appointment rate dropped from 12 to 2.1\xa0%. At 12\xa0months post-bariatric surgery, patients who undertook the new program (n\u2009=\u200982) had a mean excess weight loss (EWL) of 41.1\u2009±\u200920.3\xa0% where as those treated on the standard pathway (n\u2009=\u200961) had a mean EWL 32\u2009±\u200918.0\xa0% (p\u2009=\u20090.012).\Question: Does a Pre-Hospital Patient Education Program improve Outcomes of Bariatric Surgery?

The introduction of a pre-hospital education program has led to an improvement in attendance rates and early weight loss post-bariatric surgery.
