Fentanyl-induced cough (FIC) is a known complication, and many studies have been conducted to prevent it. The aim of this study was to evaluate the effectiveness of Diphenhydramine as an antihistamine in suppressing of FIC during induction of anesthesia. In a prospective, double-blind, randomized controlled trial, a total of 100 patients, ASA Class I and II, scheduled for elective laparoscopy surgery were randomly assigned into two equally sized groups (n=50). Diphenhydramine diluted with distilled water as 10 mg/ml. Then, patients in Group D, received diphenhydramine 30 mg (3 ml) through peripheral IV line within 1 min and Group C received the same volume normal saline 0.9% as placebo. Two min later, fentanyl 2 µg/kg was administered through the peripheral IV line within 5 sec in all patients. The occurrence and intensity of cough within 2 min after the fentanyl injection were observed and recorded by a resident who was blinded to the study groups. The frequency of PONV, analgesic requirement in the recovery room and as a secondary outcome were recorded. The incidences of FIC were 47% in the control group, and there is no cough in the diphenhydramine group (P=0.02). The frequency of PONV was also reduced in diphenhydramine group (16% vs. 40%) and less number of patients in diphenhydramine group was needed to analgesia in the recovery room (60% vs. 82%). Our study determines that diphenhydramine (30 mg, IV) bolus injection 2 min before fentanyl injection can prevent FIC and PONV and also reduce analgesic requirement inthe recovery room. © 2019 Tehran University of Medical Sciences.

Abstract Background Intravenous bolus injection of fentanyl has been frequently reported to be associated with cough reflex during patient anesthesia. However, the search for the most effective protocol continues. This study aimed to compare the effect of reducing cough reflex after injection of fentanyl in a fusion protocol by combining the injections of lidocaine and Huffing maneuver and comparing with a placebo control group, before anesthesia induction. Methods This prospective randomized controlled trial study was performed on 400 patients who were divided into four groups of combined protocol (group 1), lidocaine group (group 2), Huffing maneuver group (group 3), and the control receiving normal saline (group 4). Then patients were injected with 2. 5 μg /kg fentanyl and monitored for 2 min regarding their cough reflex, as well as the severity. Results In group one, 9 patients (9%), in group two, 45 patients (45%), 22 patients (22%) in group three, and in group four, 75 patients (75%), developed cough reflex following fentanyl injection. Also, 13 patients (13%) developed moderate and 4 (4%) developed severe coughs in the control group reported, while no reports of severe or moderate cough were among the intervention groups. There was a significant difference between the intervention group and the control group both in terms of the rate and severity of the fentanyl-induced cough. Conclusion By using a combination of lidocaine injection along and Huffing maneuver, better results can be obtained in reducing the frequency, and also the severity of cough followed by fentanyl injection. Trial registration The trial was registered with IRCT.IR (09/03/2018-No. IRCT20141009019470N74).

Abstract Background A primary challenge for HIV vaccine development is to raise antiviral antibodies capable of recognizing highly variable viral antigens. The full-length single chain (FLSC) gp120-CD4 chimeric protein was designed to present a highly conserved CD4-induced HIV-1 envelope structure that evokes cross-reactive humoral responses (Figure 1). IHV01 is an FLSC subunit vaccine formulated in alum adjuvant. The safety and immunogenicity of IHV01 was evaluated in this first-in-human phase 1a trial. Methods This randomized, double-blind placebo-controlled study involved three dose-escalating cohorts (75 µg, 150 µg, and 300 µg doses). Eligible participants were HIV-1 uninfected healthy volunteers aged 18 to 45 years. Participants in each cohort were block randomized in groups of four in a 3:1 ratio to receive either vaccine or placebo. Intramuscular injections were given on weeks 0, 4, 8, and 24. Participants were followed for an additional 24 weeks after the last immunization. Crossreactive antibody binding titers against diverse HIV envelopes and antigens and specific CD4i epitopes on gp120 were assessed. Results Sixty-five volunteers were enrolled—49 vaccine and 16 placebo. Majority (81%) of vaccinations with IHV01 produced no localized or systemic reactions; no different from the control group. The overall incidence of adverse events (AEs) was not significantly different between groups. Majority (89%) of vaccine-related AEs were mild in severity. The most common vaccine-related AEs were injection site pain (31%), pruritus (10%), and headache (10%). There were no vaccine-related serious AE, discontinuation due to AE, or intercurrent HIV infection. By the final vaccination, all subjects in all cohorts had developed antibodies against IHV01; all placebo recipients were negative. The antibodies induced by IHV01 reacted with envelope antigens from diverse HIV-1 strains (Figure 2). Conclusion IHV01 vaccine was safe, well tolerated, and immunogenic in all doses tested. The vaccine raised broadly reactive humoral responses against multiple gp120 domains, transition state structures, and CD4i epitopes. Disclosures All Authors: No reported Disclosures.

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 IntroductionHypertension is one of the most important risk factors for cardiovascular disease, and its treatment and control rates are still low worldwide. The most effective strategy is that patients with hypertension should be diagnosed and treated early. Preliminary studies showed that the Bushen Jiangya granule (BSJY) may suppress ventricular hypertrophy and inflammatory responses, lower blood pressure and protect the target organs of hypertension. We designed a randomized, double-blind, placebo-controlled trial to evaluate the efficacy of BSJY in patients with low-to-medium risk hypertension.Methods and analysisThis trial is a one-center, randomized, double-blind, placebo-controlled study. A total of 260 participants will be randomized in a 1:1 ratio to an experiment group (BSJY plus amlodipine) and a control group (placebo plus amlodipine). The trial cycle will last 8 weeks. The primary outcome is blood pressure, which is reduced to a threshold set out in Guiding Principles for Clinical Research of New Chinese Medicines. The secondary outcomes include the change in 24-h average systolic and diastolic blood pressure, heart rate variability, pharmacogenomic Evaluation, improvement in TCM Syndrome, serum pro-inflammatory/anti-inflammatory cytokines, etc. between the two groups. Safety in medication will also be evaluated. All the data will be recorded in electronic case report forms and analyzed by SPSS V.22.0.Ethics and dissemination This study has been approved by Research Ethics Committee of Guang’anmen Hospital,China Academy of Chinese Medical Sciences in Beijing, China (No. 2019-186-KY-01). The participants are volunteers, understand the process of this trial and sign an informed consent. The results of this study will be disseminated to the public through peer-reviewed journals and academic conferences. DiscussionWe hypothesize that patients with low-to-medium risk hypertension will benefit from BSJY. If successful, this study will provide evidence-based recommendations for clinicians.

Abstract Background Acute pediatric diarrhea is one of the most common causes of morbidity and mortality worldwide and seriously affects the health of children. Previous studies have shown that pediatric Tuina, a traditional Chinese medicine therapy, has potential therapeutic benefits for acute pediatric diarrhea. However, the evidence for its effectiveness is insufficient due to the lack of high-quality clinical studies. Our aim is to evaluate the efficacy of Chinese pediatric Tuina for children aged 0–6 years with acute diarrhea. Methods/design This study is a randomized, double-blind, sham-controlled trial. We will include 122 children with acute diarrhea from Dongguan Kanghua Hospital in Guangdong province, China. The patients will be allocated into either the pediatric Tuina group or the sham Tuina group in a 1:1 ratio. The treatment will last for 3 days followed by an 11-day follow-up period. Both groups will receive usual care. In addition, the experimental group will receive 15–25 min of Chinese pediatric Tuina, while the control group will receive 15–25 min of sham pediatric Tuina. Both groups will receive treatments once per day, for 3 consecutive days. Primary outcome measures are diarrhea days from baseline and diarrhea times on the third day. Secondary outcome measures are the global change rating and period of days when the stool character changes to normal. Safety assessments will be monitored during each visit. Discussion This clinical trial is designed to evaluate the efficacy of pediatric Tuina for children with acute diarrhea. We expect results to provide solid evidence and support for pediatric Tuina as an appropriate treatment for children with acute diarrhea. Trial registration ClinicalTrials.gov, NCT03005821.

Abstract Background: Intravenous use of sufentanil can elicit cough. This study aimed to evaluate the inhibitory effect of pre-injection of a mall dose of remifentanil on sufentanil-induced cough during the induction of general anesthesia. Methods: This prospective, randomized, controlled trial was conducted from January 10, 2019 to March 01, 2019. A total of 100 patients undergoing elective surgery under general anesthesia were enrolled, and at last 84 patients were included and randomly allocated into two equal size groups (n=42): Patients in the Remifentanil group (R group) received an intravenous infusion of remifentanil 0.3 µg/kg (diluted to 2 ml) 1 minute before sufentanil injection; patients in the Control group (C group) received 2 ml of normal saline (NS) at the same time point. Injections of patients in both groups were completed within 5 seconds. Then, sufentanil 0.5 µg/kg was injected within 5 seconds and the number of coughs that occurred within 1 minute after sufentanil injection were recorded. One minute after sufentanil injection, etomidate 0.3 mg/kg and cisatracurium 0.15 mg/kg were given for general anesthesia induction irrespective of the presence or absence of cough. The mean arterial pressure (MAP) and heart rate (HR) at time points just before remifentanil pretreatment administration (T0), 3 minutes after administration (T1), 1 minute after intubation (T2), and 3 minutes after intubation (T3) were recorded. Results: The incidence of cough in patients in the R group and C group was 4.8% and 31%, respectively. Compared with group C, the incidence and severity of cough in group R was significantly lower (P <0.01). No significant differences were observed in MAP and HR at the time of general anesthesia induction between the two groups (P> 0.05). Conclusion: Pretreatment with a small dose of remifentanil effectively and safely reduced the incidence and severity of cough induced by sufentanil during anesthesia induction and can be used as an alternative treatment to inhibit coughing caused by sufentanil.

Background: Insomnia is a common clinical manifestation in patients with depression. Insomnia is not only a depression symptom but also an independent risk factor for recurrence. Cordyceps militaris (C. militaris) is thought to have the potential to treat insomnia. This study aimed to examine the efficacy and safety of duloxetine with C. militaris in improving sleep symptoms in patients with depression.Methods: This study was a single-center, randomized, double-blind, placebo-controlled study that recruited outpatients admitted to Beijing Anding hospital from January 2018 to January 2019. Major depressive disorder (MDD) with insomnia was diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) criteria and Mini-International Neuropsychiatric Interview (M.I.N.I.). Eligible subjects will be randomly assigned to two treatment groups in a 1:1 ratio, and receive treatment and follow-up of about 6 weeks of duloxetine plus Cordyceps militaris or placebo, respectively. The severity of depression and insomnia was evaluated at baseline and at 1, 2, 4, and 6 weeks using the 17-item Hamilton Depression Scale (HAMD-17) and Athens Insomnia Scale (AIS).Results: A total of 59 subjects were included in the study (31 in the placebo group and 28 in the C. militaris group). 11 (18.6%) participants withdrew during the study period, 5 (17.9%) in the C. militaris group, and 6 (19.3%) in the placebo group. Depressive and sleep symptoms in all patients reduced over time. We found that the total scores of AIS and its subscales decreased more in the placebo group compared to the C. militaris group (p &lt; 0.05). Secondary outcome revealed that there were no significant differences between the two groups in total HAMD-17 and its sleep factor scores (p &gt; 0.05) at 1, 2, 4, and 6 weeks after treatment initiation. The incidences of adverse events were not significantly different between the two groups (all p &gt; 0.05).Conclusion:C. militaris at the current dose and duration did not improve sleep symptoms in patients with depression, but it is safe with rare side effects.

When studying treatments for psychiatric or mental diseases in a placebo-controlled trial, we may consider use of the sequential parallel comparison design to reduce the number of patients needed through the reduction of the high placebo response rate. Under the assumption that the odds ratio of responses is constant between phases in the sequential parallel comparison design, we derive the conditional maximum likelihood estimator for the odds ratio. On the basis of the conditional likelihood, we further derive three asymptotic interval and an exact interval estimators for the odds ratio of responses. We employ Monte Carlo simulation to evaluate the performance of these interval estimators in a variety of situations. We find that the asymptotic interval and exact interval estimators developed here can all perform well. We use the double-blind, placebo-controlled study assessing the efficacy of a low dose of aripiprazole adjunctive to antidepressant therapy for treating patients with major depressive disorder to illustrate the use of these estimators.

ObjectivesTo evaluate the morphine-sparing effects of the sequential treatment versus placebo in subjects undergoing total knee arthroplasty (TKA), the effects on pain relief, inflammation control and functional rehabilitation after TKA and safety.DesignDouble-blind, pragmatic, randomised, placebo-controlled trial.SettingFour tertiary hospitals in China.Participants246 consecutive patients who underwent elective unilateral TKA because of osteoarthritis (OA).InterventionsPatients were randomised 1:1 to the parecoxib/celecoxib group or the control group. The patients in the parecoxib/celecoxib group were supplied sequential treatment with intravenous parecoxib 40 mg (every 12 hours) for the first 3 days after surgery, followed by oral celecoxib 200 mg (every 12 hours) for up to 6 weeks. The patients in the control group were supplied with the corresponding placebo under the same instructions.Primary and secondary outcome measuresThe primary endpoint was the cumulative opioid consumption at 2 weeks post operation (intention-to-treat analysis). Secondary endpoints included the Knee Society Score, patient-reported outcomes and the cumulative opioid consumption.ResultsThe cumulative opioid consumption at 2 weeks was significantly smaller in the parecoxib/celecoxib group than in the control group (median difference, 57.31 (95% CI 34.66 to 110.33)). The parecoxib/celecoxib group achieving superior Knee Society Scores and EQ-5D scores and greater Visual Analogue Scale score reduction during 6 weeks. Interleukin 6, erythrocyte sedation rate and C-reactive protein levels were reduced at 72 hours, 2 weeks and 4 weeks and prostaglandin E2 levels were reduced at 48 hours and 72 hours in the parecoxib/celecoxib group compared with the placebo group. The occurrence of adverse events (AEs) was significantly lower in the parecoxib/celecoxib group.ConclusionsThe sequential intravenous parecoxib followed by oral celecoxib regimen reduces morphine consumption, achieves better pain control and functional recovery and leads to less AEs than placebo after TKA for OA.Trial registration numberClinicalTrials.gov (ID:NCT02198924).
