Antiemetics are medications that are frequently used in the pre-hospital setting. However, recent evidence indicates that antiemetics are ineffective in reducing undifferentiated nausea scores and vomiting rates. The aim of this study is to evaluate the efficacy and safety of antiemetics administered in the pre-hospital setting. This is a systematic review employing PRISMA guidelines of seven studies selected that included randomised controlled trials and prospective studies, investigating the use of antiemetics in the pre-hospital setting...

Background: α-Cyclodextrin (α-CD), a soluble dietary fiber, may improve abnormal plasma lipids and promote weight loss. Preliminary evidence suggests that it may exert these effects by binding dietary fat and reducing absorption; this has not been tested in humans. Objective: The primary objective was to test whether supplemental α-CD increases fecal content of dietary lipid in humans. Methods: This was a randomized, double-blind, placebo-controlled, crossover study completed at the Mayo Clinic...

Traditional Chinese medicine (TCM) has served the Chinese people since antiquity, and is playing an important role in today's healthcare. However, there has been controversy in the use of these traditional herbs due to unclear components and absence of scientific proof. As China plans to modernize traditional medicine, successful attempts to better understand the molecular mechanisms of TCM have been made by focusing on isolating active ingredients from these remedies. In this review, we critically examined the current evidence on atheroprotective effects of bioactive compounds from TCM using in vitro or in vivo models in the past two decades...

Antibiotics are frequently administered for prophylaxis of fever in neutropenic children with cancer. This strategy is mainly derived from adults' data, and various pediatric studies evidenced the effectiveness of antibiotics (e.g. fluorquinolones) in the prevention of febrile neutropenia. However, only two pediatric randomized, double blind, placebo-controlled trials have been performed, with a total of 262 leukemic children enrolled, and no other one was ever powered for analyzing effectiveness over other infectious complications...

OBJECTIVE: Following Roux-en-Y gastric bypass (RYGB), elevated parathyroid hormone (PTH) levels potentially harmful to bone health are commonly observed. Owing to assumed superior absorption, calcium citrate is often recommended over calcium carbonate following RYGB for the treatment of elevated PTH. We aimed to investigate the impact of either calcium carbonate or calcium citrate (1200 mg elementary calcium) in patients with elevated PTH levels following RYGB. DESIGN: Clinical, double-blinded, randomized controlled trial of a 12-week-duration at a Danish University Hospital...

BACKGROUND: Bipolar disorder (BPD) is a chronic and recurrent mood disorder characterized by episodes of mania, hypomania, and major depression. Based on available evidence, mitochondrial dysfunction, oxidative stress, and inflammation have important roles in the pathophysiology of bipolar depression. More specifically, it seems that coenzyme Q10 (CoQ10), a mitochondrial modulator, as well as an antioxidant and anti-inflammatory agent, might be effective in modulating these pathophysiological pathways...

PURPOSE/BACKGROUND: Some therapeutic drug monitoring studies suggest that increased weight is associated with small increases in clozapine concentrations. The goal of this study was to reanalyze a US double-blind study using a sophisticated statistical model to test whether weight gains from baseline or increases in percentage of body fat from baseline, computed from a published equation, are associated with increased total plasma clozapine concentrations after controlling for the effects of smoking and sex...

BACKGROUND: D-Cycloserine has potential to enhance exposure therapy outcomes. The current study presents a preliminary randomized, placebo-controlled double-blind pilot trial of DCS-augmented one-session treatment (OST) for youth (7-14 years) with specific phobia. A secondary aim of this pilot study was to explore the effects of youth age and within-session fear reduction as potential moderators of DCS outcomes in order to generate hypotheses for a larger trial. It was hypothesized that DCS would be associated with greater improvements than placebo, that children (7-10 years) would have greater benefits than adolescents (11-14 years), and that DCS effects would be stronger for participants with the greater within-session fear reduction during the OST...

Background: Levodopa has been widely used and regarded as the most effective therapy for Parkinson's disease (PD), but long-term treatment with oral levodopa may result in motor fluctuations and involuntary movements (dyskinesias). There is evidence to suggest that Continuous infusion of levodopa-carbidopa intestinal gel (LCIG) can effectively manage motor and non-motor complications in PD, but clinical studies investigating this have yielded inconsistent results. This systematic review and meta-analysis was performed to examine the efficacy and safety of LCIG for patients with PD...

Background and Aims: Catheter-related bladder discomfort (CRBD) has started to gain recognition as a problem in early postoperative care. Dexmedetomidine reduces bladder contractility via M3 muscarinic receptor antagonism and α-2 receptor agonism, apart from its concomitant therapeutic benefits, such as sedation and sympatholysis, in a postoperative period. We, therefore, evaluated the efficacy of dexmedetomidine in reducing incidence and severity of CRBD. Material and Methods: This prospective, randomized, double-blind, placebo-controlled trial done on 110 voluntary kidney donors for live related kidney transplantations were planned for laparoscopic donor nephrectomy...
