Objective.To evaluate the efficacy of traditional Chinese herbal ChuanXiong Ding Tong herbal formula granule (CXDT-HFG) for migraine patients with “the Syndrome of Liver Wind and Blood Stasis.”Methods.150 migraine patients were recruited and assigned randomly in a double-blind, placebo-controlled study to receive CXDT-HFG (n=99) plus necessary analgesics, or placebo (n=51) plus necessary analgesics for 16 weeks (12 weeks’ intervention and 4 weeks’ follow up). Outcome measures included migraine days, frequency of migraine attacks, analgesics consumption for acute treatment, and the proportion of responders as well as the visual analogue scale (VAS) scores and intensity for pain.Results.Compared with the placebo group, the CXDT-HFG group showed significant reduction in migraine days and attacks frequency at week 12 and follow-up period (P<0.05) as well as in the reduction of VAS scores at follow-up period.There was significant difference in the proportion of responders between the two groups at follow-up period (P=0.014). However there were no significant differences between the two groups in analgesics consumption (P>0.05). Conclusion.CXDT-HFG was more effective than placebo in decreasing days of migraine attacks, frequency, VAS scores, and relieving pain intensity for migraine patients.

Objective. To assess the short-term efficacy and safety of two kinds of Traditional Chinese herbal patches, Fufang Nanxing Zhitong Gao (FNZG) and Shangshi Jietong Gao (SJG), for painful knee osteoarthritis (OA).Methods. Patients were randomly enrolled in a double-blind, placebo-controlled study to receive FNZG (n=60), SJG (n=60), or placebo patch (n=30) for 7 days. Outcome measures included visual analogue scale (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Traditional Chinese Medicine Syndrome Questionnaire (TCMSQ) subscale.Results. Although there was no significant difference among, three groups in short-term pain management, patients receiving FNZG got significant improvement in symptom of fear of coldness as compared with placebo patch (P=0.029). The most common local adverse events of rash, itching, erythema, and slightly damaged skin were observed in 7% of participants.Conclusions. FNZG may be a useful treatment for symptom of knee OA and merits long-term study in broader populations.

✓ In this study, 417 patients undergoing “clean” elective neurosurgical operative procedures were randomized to receive a broad-spectrum antibiotic (piperacillin) or placebo given as three perioperative doses, each 6 hours apart. Randomization was carried out by hospital pharmacists, and the investigators remained blinded until the end of the study. Twenty cases were excluded from analysis because either an unforeseen second operation was performed or antibiotic therapy was initiated within 30 days after surgery to treat infection or the risk of infection. Twelve of the 205 patients treated with placebo developed postoperative wound sepsis, and four of the 192 piperacillin-treated patients developed wound sepsis — a statistically significant difference (p < 0.05, Fisher's exact test). Piperacillin thus appeared to reduce the incidence of neurosurgical wound infection in this study.

ObjectiveIBS is associated with an intestinal dysbiosis and faecal microbiota transplantation (FMT) has been hypothesised to have a positive effect in patients with IBS. We performed a randomised, double-blind placebo-controlled trial to investigate if FMT resulted in an altered gut microbiota and improvement in clinical outcome in patients with IBS.DesignWe performed this study in 52 adult patients with moderate-to-severe IBS. At the screening visit, clinical history and symptoms were assessed and faecal samples were collected. Patients were randomised to FMT or placebo capsules for 12 days and followed for 6 months. Study visits were performed at baseline, 1, 3 and 6 months, where patients were asked to register their symptoms using the IBS-severity scoring system (IBS-SSS) and IBS-specific quality of life (IBS-QoL). Prior to each visit, faecal samples were collected.ResultsA significant difference in improvement in IBS-SSS score was observed 3 months after treatment (p=0.012) favouring placebo. This was similar for IBS-QoL data after 3 months (p=0.003) favouring placebo. Patients receiving FMT capsules had an increase in faecal microbial biodiversity while placebos did not.ConclusionIn this randomised double-blinded placebo-controlled study, we found that FMT changed gut microbiota in patients with IBS. But patients in the placebo group experienced greater symptom relief compared with the FMT group after 3 months. Altering the gut microbiota is not enough to obtain clinical improvement in IBS. However, different study designs and larger studies are required to examine the role of FMT in IBS.Trial registration numberNCT02788071.

The eye movement desensitization and reprocessing (EMDR) individual protocol for paraprofessional use in acute trauma situations (EMDR-PROPARA) is part of a project developed at the initiative of Dr. Francine Shapiro. This randomized clinical trial examined the effectiveness of the protocol administered by experienced EMDR therapists. There were 39 traumatized first responders on active duty randomly assigned to receive two 90-min sessions of either EMDR-PROPARA or of supportive counseling. Participants in the EMDR-PROPARA group showed benefits immediately after treatment, with their scores on the Short PTSD Rating Interview (SPRINT) showing further decreases at 3-month follow-up. In comparison, supportive counseling participants experienced a nonsignificant decrease after treatment and an increase in the SPRINT scores at the second follow-up. The significant difference between the two treatments provides preliminary support for EMDR-PROPARA’s effectiveness in reducing severity of posttraumatic symptoms and subjective global improvement. More controlled research is recommended to evaluate further the efficacy of this intervention.

Abstract Introduction Venous thromboembolism (VTE) is associated with a considerable risk for morbidity and recurrence and related hospitalizations. In the Apixaban after the Initial Management of Pulmonary Embolism and Deep Vein Thrombosis with First-Line Therapy-Extended Treatment (AMPLIFY-EXT) trial, a double-blind placebo-controlled trial with 12 months of treatment, two doses of apixaban (2.5 mg and 5 mg, twice daily) versus placebo significantly reduced symptomatic recurrent VTE or all-cause death without increasing the rate of major bleeding among 2,482 VTE patients who had completed 6-12 months of anticoagulation therapy. In this study, the effects of apixaban therapy versus placebo on medical hospitalization during AMPLIFY-EXT trial were evaluated. Methods A total of 2,477 patients who received study drugs were included in the analysis. All-cause hospitalizations during the trial were captured by dedicated case report forms. Outcomes of interest were; rate of hospitalizations and time from randomization to the first hospitalization. Patients were censored at either death, loss to follow-up, or end of study, whichever came first. Effects of treatment with apixaban versus placebo on the rates of hospitalization were assessed using Cox proportional hazards regression models. Results During a mean follow-up of 12.3 months, 138 patients were hospitalized at least once, 62 (7.5%/year) in the placebo group (n=826), 42 (4.8%/year) in the apixaban 2.5 mg group (n=840), and 34 (4.0%/year) in the apixaban 5 mg group (n=811). Compared with placebo, apixaban 2.5 mg [hazard ratio (HR) 0.65, 95% confidence interval (CI) 0.44–0.96; p=0.030] and 5 mg (HR 0.54, 95%CI 0.36–0.83, p=0.004) were both associated with significant reduction in hospitalization. There was no significant difference in hospitalizations between the 2 doses of apixaban (5 mg vs. 2.5 mg: HR 0.84, 95%CI 0.53–1.32, p=0 .445). The mean time to first hospitalization was 153.7 days in the placebo group, 196.9 days in the apixaban 2.5 mg group, and 202.4 days in the apixaban 5 mg group (Figure). Conclusions Extended anticoagulation with apixaban at either a dose of 5 mg or 2.5 mg significantly reduced the risk of hospitalization, possibly due to the reduction in VTE recurrence.

9007 Introduction: Although pyridoxine has been used empirically for the prevention of HFS associated with capecitabine, its efficacy has not been proven yet. We performed a prospective randomized double-blind study to determine whether pyridoxine can prevent the development of HFS when given concurrently with capecitabine. Method: Chemotherapy-naive patients (pts) with gastrointestinal tract cancers who were going to have capecitabine-containing chemotherapy were randomized to receive either oral pyridoxine (200 mg/day) or placebo daily during chemotherapy after stratified by chemotherapy regimen: 1) capecitabine alone, 2) capecitabine and cisplatin, or 3) docetaxel, capecitabine, and cisplatin. The patients were observed until grade 2 or 3 HFS (by NCI CTC version 2.0) developed or capecitabine containing chemotherapy ended. When grade 2 or 3 HFS developed in pts in placebo group, the pts were randomized again to receive either pyridoxine or placebo for next cycle of chemotherapy in order to determine whether pyridoxine could improve the HFS. Result: From Jun 2004 to Oct 2005, total 389 pts were entered onto the study. But, 29 pts (15 in placebo group and 14 in pyridoxine group) were excluded from the study because of ineligibility or pts’ refusal. Pts’ characteristics were well balanced between the 2 groups. Grade 2 or 3 HFS developed in 55 of 180 (30.6%) pts in placebo group and in 57 of 180 (31.7%) pts in pyridoxine group. (p=0.788) The median cycles of chemotherapy to grade 2 or 3 HFS was 3 in both groups. The mean cumulative dose of capecitabine until occurrence of grade 2 or 3 HFS was not different statistically between the two groups. (221,157.5 mg/m2 vs. 259,808.5 mg/m2, p=0.788). Total 44 of 55 pts in placebo group who had grade 2 or 3 HFS were randomized to receive either placebo or pyridoxine at next cycle. There was no significant difference between the two groups in the proportion of pts with improvement of HFS (43% vs 48%, p=0.94). Conclusion: These results indicated that pyridoxine is not effective for the prevention of HFS associated with capecitabine therapy. No significant financial relationships to disclose.

9002 Background: Cancer-related-fatigue (CRF) is the most common and distressing symptoms in patients with advanced cancer. Currently, there is no standard treatment for CRF. Although corticosteroids have been used in the treatment of CRF, there are no well-powered placebo-controlled trials that used a validated CRF outcome measure. The primary objective of this prospective, randomized, double-blind, placebo-controlled study is to compare the effect of DM versus placebo on CRF. Methods: Advanced cancer patients with fatigue ≥ 4/10 on the Edmonton Symptom Assessment Scale (ESAS) and at least 2 other CRF-related symptoms (pain, nausea, appetite, depression, anxiety or sleep disturbance ≥ 4/10), normal cognition, no infections and hemoglobin ≥ 9 g/L were eligible for enrollment. Patients were randomized to either receive dexamethasone 4 mg orally twice a day for 15 days (primary end point) or matching placebo. The primary outcome was the day 15 change in Functional Assessment of Chronic Illness-Fatigue (FACIT-F) subscale scores. Differences in the group means (normal distribution) were analyzed using the two-sample t-test. Results: In 83 evaluable patients (43 DM and 40 placebo), median age was 60 years, 61% were white, and 53% were female. There was no difference in the demographics and fatigue (FACIT-F subscale) between DM and placebo groups except for sex (p=0.02). The mean (SD) FACIT-F subscores at baseline and at day 15 for DM were 18 (11) and 27 (11) (p<0.001) and for placebo were 21 (9) and 24 (12) (p=0.06), respectively. Mean improvement in FACIT-F subscale was significantly higher in the DM group compared to placebo (9.6 (11) vs. 3.1 (9.7), p=0.005). We found a significant difference in ESAS physical distress (p=0.02), but no differences in ESAS overall symptom distress (p=0.11) and ESAS psychological distress (P=0.88) between DM and placebo. There were insignificantly higher numbers of grade ≥3 toxicities in patients who received DM than in patients who received placebo (20/42 vs. 18/47, p=0.37). Conclusions: Dexamethasone was more effective than placebo in reducing CRF in patients with advanced cancer. Long-term safety studies are needed.

Background. Local periarticular injection with bupivacaine alone in TKA has not been studied. Thus, we aimed to examine the effectiveness of local periarticular injection with bupivacaine for post-operative pain control in TKA.Method. Sixty patients undergoing TKA by a single surgeon were randomly assigned into two groups in a double-blind, placebo-controlled study. In the injection group, patients received periarticular injections with 0.25% bupivacaine before wound closure; in the control group, patients received a 0.9% normal saline injection. Both groups received the same anesthetic procedure, post-operative pain control, and rehabilitation protocol.Results. There was a significant reduction in post-operative morphine consumption in the first six hours after the operation (mean 0.9 mg and 2.43 mg,P=0.01), but there was no significant difference in post-operative morphine consumption between six hours and ninety-six hours after the operation, visual analogue scale (VAS) score, morphine side effects during the first 96 hours, length of hospital stay, or complications from morphine consumption.Conclusion. Local periarticular injection with bupivacaine alone before wound closer was shown to be an effective method to improve pain control after TKA with a few complications and ease of use.

Abstract In this double-blind, placebo-controlled study, 363 patients with untreated multiple myeloma were randomized to receive either melphalan-prednisone and thalidomide (MPT) or melphalan-prednisone and placebo (MP). The dose of melphalan was 0.25 mg/kg and prednisone was 100 mg given daily for 4 days every 6 weeks until plateau phase. The dose of thalidomide/placebo was escalated to 400 mg daily until plateau phase and thereafter reduced to 200 mg daily until progression. A total of 357 patients were analyzed. Partial response was 34% and 33%, and very good partial response or better was 23% and 7% in the MPT and MP arms, respectively (P < .001). There was no significant difference in progression-free or overall survival, with median survival being 29 months in the MPT arm and 32 months in the MP arm. Most quality of life outcomes improved equally in both arms, apart from constipation, which was markedly increased in the MPT arm. Constipation, neuropathy, nonneuropathy neurologic toxicity, and skin reactions were significantly more frequent in the MPT arm. The number of thromboembolic events was equal in the 2 treatment arms. In conclusion, MPT had a significant antimyeloma effect, but this did not translate into improved survival. This trial was registered at www.clinicaltrials.gov as #NCT00218855.
