    Cobalamin (vitamin B12) deficiency, the most common cause of megaloblastic anemia, is treated with intramuscular (IM) cobalamin. It has been suggested by some investigators that oral (p.o.) cobalamin treatment may be as effective in the treatment of this condition, with the advantages of ease of administration and lower cost. This study assessed the effects and cost of p.o. versus i.m. cobalamin treatment in patients with megaloblastic anemia due to cobalamin deficiency. This was a 90-day, prospective, randomized, open-label study conducted at the Division of Hematology, Department of Internal Medicine, Adnan Menderes University Research and Practice Hospital (Aydin, Turkey). Patients aged > or =16 years with megaloblastic anemia due to cobalamin deficiency were randomized to receive 1000-microg cobalamin p.o. once daily for 10 days (p.o. group) or 1000-microg cobalamin i.m. once daily for 10 days (i.m. group). After 10 days, both treatments were administered once a week for 4 weeks, and after that, once a month for life. Patients were assessed for the presence of reticulocytosis between treatment days 5 and 10 until it was detected. Therapeutic effectiveness was assessed by measuring hematologic parameters on days 0, 10, 30, and 90 and serum vitamin B12 concentration on days 0 and 90. The Mini-Mental State Examination was used before and after the B12 therapy for cognitive function assessment and 125-Hz diapozone was used for vibration threshold testing. Neurologic sensory assessment, including soft-touch and pinprick examinations, was used to identify neuropathy at baseline and study end. Tolerability was assessed using laboratory tests and patient interview. Cost was assessed using the cost of the study drug and of the injection. Sixty patients completed the study 26 in the p.o. group (16 men, 10 women; mean [SD] age, 60 [15] years) and 34 in the i.m. group (17 men, 17 women; mean [SD] age, 64 [10] years). Reticulocytosis was observed in all patients. In the p

    Comparing the effects of metformin or orlistat on hormone, lipid profile and ovulation status in obese women with polycystic ovary syndrome. A total of 80 women were prospectively recruited to receive either metformin (n = 40) or orlistat (n = 40). Weight, BMI, waist, serum LH, total serum testosterone and lipid profile were assessed at baseline and after 3 months. The subjects' ovulatory status was assessed after 3 months. There was no significant difference in ovulation between the two treatment groups (30% vs 15%). Treatment with either drug showed a significant decline in body weight, BMI (Body Mass Index), and waist circumference, but the degree of decline in both groups was the same. Patients who were treated with orlistat, showed a significant reduction in total testosterone and serum lipid. Women in metformin group showed a significant reduction in serum LH. Both metformin and orlistat showed a similar effect on weight loss and ovulation rates.

    To assess the efficacy and safety of modest blood pressure (BP) reduction with valsartan within 48 h after symptom onset in patients with acute ischemic stroke and high BP. This was a multicenter, prospective, randomized, open-label, blinded-end-point trial. A total of 393 subjects were recruited at 28 centers and then randomly assigned in a 1:1 ratio to receive valsartan (n = 195) or no treatment (n = 198) for seven-days after presentation. The primary outcome was death or dependency, defined as a score of 3-6 on the modified Rankin Scale (mRS) at 90 days after symptom onset. Early neurological deterioration (END) within seven-days and 90-day major vascular events were also assessed. There were 372 patients who completed the 90-day follow-up. The valsartan group had 46 of 187 patients (24·6%) with a 90-day mRS 3-6, compared with 42 of 185 patients (22·6%) in the control group (odds ratio [OR], 1·11; 95% confidence interval [CI], 0·69-1·79; P = 0·667). The rate of major vascular events did not differ between groups (OR, 1·41; 95% CI, 0·44-4·49; P = 0·771). There was a significant increase of END in the valsartan group (OR, 2·43; 95% CI, 1·25-4·73; P = 0·008). Early reduction of BP with valsartan did not reduce death or dependency and major vascular events at 90 days, but increased the risk of END. © 2015 World Stroke Organization.

    This meta-analysis aimed to determine whether ambulatory blood pressure monitoring (ABPM) results from double-blind, placebo-controlled (DBPC) and prospective, randomized, open-label, blinded-endpoint (PROBE) hypertension trials are statistically comparable. Two DBPC and three PROBE parallel-group studies were selected from an angiotensin II receptor blocker clinical programme. These were fixed-dose studies involving similar mild to moderate hypertensive patient populations. All used SpaceLabs 90207 ABPM devices, and each comprised a 4-week placebo period and a 4-8-week treatment period. Data from patients receiving telmisartan 80 mg were used to compare the results of DBPC (126 patients) and PROBE (734 patients) trials. The analysis had approximately 87% power to show equivalence between the two design types in terms of ruling out differences of >or= 3 mmHg in SBP and >or= 2 mmHg in DBP. Office blood pressure was also compared. The change from baseline in mean 24-h ambulatory SBP was -12.2 mmHg in DBPC trials and -12.3 mmHg in PROBE trials, a rounded difference of 0.2 mmHg [95% confidence interval (CI): -1.8, 2.1]. The change from baseline in mean 24-h ambulatory DBP was -7.7 mmHg in DBPC trials versus -7.9 mmHg in PROBE trials, a difference of 0.2 mmHg (95% CI: -1.1, 1.5). Ambulatory pulse pressure results were identical. Thus, changes in mean 24-h ambulatory blood pressure from the DBPC and PROBE trials in this meta-analysis are statistically equivalent in terms of ruling out a difference of >or= 3 mmHg in SBP and >or= 2 mmHg in DBP. This supports the validity of the PROBE design in assessing antihypertensive efficacy based on blinded ABPM measurements.

    Full Text Available Abstract Background Maintenance hemodialysis (HD patients universally suffer from excess toxin load. Hemodiafiltration (HDF has shown its potential in better removal of small as well as large sized toxins, but its efficacy is restricted by inter-compartmental clearance. Intra-dialytic exercise on the other hand is also found to be effective for removal of toxins; the augmented removal is apparently obtained by better perfusion of skeletal muscles and decreased inter-compartmental resistance. The aim of this trial is to compare the toxin removal outcome associated with intra-dialytic exercise in HD and with post-dilution HDF. Methods/design The main hypothesis of this study is that intra-dialytic exercise enhances toxin removal by decreasing the inter-compartmental resistance, a major impediment for toxin removal. To compare the HDF and HD with exercise, the toxin rebound for urea, creatinine, phosphate, and β2-microglobulin will be calculated after 2 hours of dialysis. Spent dialysate will also be collected to calculate the removed toxin mass. To quantify the decrease in inter-compartmental resistance, the recently developed regional blood flow model will be employed. The study will be single center, randomized, self-control, open-label prospective clinical research where 15 study subjects will undergo three dialysis protocols (a high flux HD, (b post-dilution HDF, (c high flux HD with exercise. Multiple blood samples during each study session will be collected to estimate the unknown model parameters. Discussion This will be the first study to investigate the exercise induced physiological change(s responsible for enhanced toxin removal, and compare the toxin removal outcome both for small and middle sized toxins in HD with exercise and HDF. Successful completion of this clinical research will give important insights into exercise effect on factors responsible for enhanced toxin removal. The knowledge will give confidence for implementing

    To determine safety and perform a preliminary assessment of dose-dependent efficacy of dextromethorphan in normalizing electrographic spikes, clinical seizures, and behavioral and cognitive functions in girls with Rett syndrome. We used a prospective randomized, open-label trial in fast metabolizers of dextromethorphan to examine the effect of dextromethorphan on core clinical features of Rett syndrome. Interictal spike activity and clinical seizures were determined using EEG and parent reporting. Cognitive data were obtained using the Mullen Scales of Early Learning and Vineland Adaptive Behavior Scales, while behavioral data were obtained from parent-completed checklists, the Aberrant Behavior Checklist-Community Version, and the Screen for Social Interaction. Anthropometric data were obtained according to the National Health and Nutrition Examination Survey. The Rett Syndrome Severity Scale provided a clinical global impression of the effect of dextromethorphan on clinical severity. Dextromethorphan is safe for use in 3- to 15-year-old girls with Rett syndrome. Thirty-five girls were treated with 1 of 3 doses of dextromethorphan over a period of 6 months. Statistically significant dose-dependent improvements were seen in clinical seizures, receptive language, and behavioral hyperactivity. There was no significant improvement in global clinical severity as measured by the Rett Syndrome Severity Scale. Dextromethorphan is a potent noncompetitive antagonist of the NMDA receptor channel that is safe for use in young girls with Rett syndrome. Preliminary evidence suggests that dextromethorphan may improve some core features of Rett syndrome. This study provides Class IV evidence that dextromethorphan at various doses does not change EEG spike counts over 6 months, though precision was limited to exclude an important effect. © 2017 American Academy of Neurology.

    The purpose of this study was to compare the effects of lateral abdominal transversus abdominis plane block (TAP block) and iliohypogastric/ilioinguinal nerve block (IHINB) under ultrasound guidance for postoperative pain management of inguinal hernia repair. Secondary purposes were to compare the complication rates of the two techniques and to examine the effects of TAP block and IHINB on chronic postoperative pain. This was a prospective randomized controlled open-label study. After approval of the Research Ethics Board, a total of 90 patients were allocated to three groups of 30 by simple randomized sampling as determined with a priori power analysis. Peripheral nerve blocks (TAP block or IHINB) were administered to patients following subarachnoid block according to their allocated group. Patient pain scores, additional analgesic requirements and complication rates were recorded periodically and compared. Pain scores were significantly lower in the study groups (p block group [GT] 266.6 ± 119.7 min; IHINB group [GI] 247.2 ± 128.7 min; and control group [GC] 79.1 ± 66.2 min; p block or IHINB for patients undergoing inguinal herniorrhaphy reduces the intensity of both acute and chronic postoperative pain and additional analgesic requirements.

    Full Text Available Aim and Objective: To compare efficacy and safety of escitalopram with desvenlafaxine in the treatment of major depression.Materials and Methods: A total of 60 patients of depression were randomized into two groups after meeting inclusion criterion. In the first 3 weeks, escitalopram 10 mg/day was given and then 20 mg/day for the next 3 weeks in group 1 (n = 30. Desvenlafaxine in the first 3 weeks was given 50 mg/day and 100 mg/day for the next 3 weeks in group 2 (n = 30. The parameters evaluated during the study were efficacy assessments byHamilton Scale of Rating Depression (HAM-D, Hamilton Rating Scale of Anxiety (HAM-A, and Clinical Global Impression (CGI. Safety assessments were done by UKU-scale. Results: Escitalopram and desvenlafaxine significantly (P < 0.001, reduced HAM-D, HAM-A, and CGI scores from their respective base lines. However, on comparison failed show any statistical difference at 3 and 6 weeks of treatment. Escitalopram and desvenlafaxine were both found to be safe and well-tolerated and there was not much difference between the two groups as evident from UKU Scale and their effect on various biochemical parameters. Conclusion: The present study demonstrated similar efficacy and safety in reducing depression and anxiety with both escitalopram and desvenlafaxine, but clinical superiority of one drug over the other cannot be concluded due to limitations of the small sample size.

    Linezolid, an oxazolidinone, substantially improves treatment outcomes of multidrug-resistant tuberculosis and extensively drug-resistant tuberculosis. We started a trial to test whether the use of linezolid instead of ethambutol could increase the rate of sputum culture conversion as of 8 weeks of treatment in patients with drug-susceptible tuberculosis. This is a phase II, multicenter, randomized study with three arms. We are enrolling patients with pulmonary tuberculosis without rifampicin resistance screened by the Xpert MTB/RIF® assay. The standard treatment arm uses isoniazid (6 months), rifampicin (6 months), pyrazinamide (2 months), and ethambutol (2 months). Experimental arm 1 uses linezolid (600 mg/day) for 4 weeks instead of ethambutol. Experimental arm 2 uses linezolid (600 mg/day) for 2 weeks instead of ethambutol. The primary outcome is the sputum culture conversion rate on liquid media after 2 months of treatment. Secondary outcomes include the sputum culture conversion rate on solid media after 2 months of treatment, time to sputum culture conversion on liquid and solid media, cure rate, and treatment success rate. The frequencies of total adverse events (AEs) and serious AEs will be described and documented. Based on an α = 0.05 level of significance, a power of 85%, a 15% difference in the culture conversion rate after 2 months between the control arm and experimental arm 1 (75% vs. 90%), a 10% default (loss to follow-up) rate, and a 10% culture failure, the required number per arm was calculated to be 143 (429 in total). This trial will reveal the effectiveness and safety of 2 or 4 weeks of use of linezolid instead of ethambutol for patients with drug-susceptible pulmonary tuberculosis. If a new regimen including linezolid shows a higher culture conversion rate by week 8, and is safe, it could be tested as a 4-month antituberculosis treatment regimen in the future.

  11. Assessing Odor Level when Using PrePex for HIV Prevention: A Prospective, Randomized, Open Label, Blinded Assessor Trial to Improve Uptake of Male Circumcision.

    Full Text Available The PrePex is a WHO--prequalified medical device for adult male circumcision for HIV prevention. The Government of Rwanda was the first country to implement the PrePex device and acts as the leading center of excellence providing training and formal guidelines. As part of the Government's efforts to improve PrePex implementation, it made efforts to improve the psychological acceptability of device by men, thus increasing uptake with VMMC in sub-Saharan Africa. Some men who underwent the PrePex procedure complained of foreskin odor while wearing the PrePex 3-7 days after it was placed. This complaint was identified as potential risk for uptake of the device. Researchers from Rwanda assumed there is a possible relation between the level of foreskin odor and patient foreskin hygiene technique. The Government of Rwanda decided to investigate those assumptions in a scientific way and conduct a trial to test different hygiene-cleaning methods in order to increase the acceptability of PrePex and mitigate the odor concern. The main objective of the trial was to compare odor levels between three arms, having identical personal hygiene but different foreskin hygiene techniques using either clear water with soap during a daily shower, soapy water using a syringe, or chlorhexidine using a syringe. One hundred and one subjects were enrolled to the trial and randomly allocated into three trial arms. Using chlorhexidine solution daily almost completely eliminated odor, and was statistically significant more effective that the other two arms. The trial results suggest that odor from the foreskin, while wearing the PrePex device, could be related to the growth of anaerobic bacteria, which can be prevented by a chlorhexidine cleaning method. This finding can be used to increase acceptability by men when considering PrePex as one of the leading methods for HIV prevention in VMMC programs.

    The rates of stent failure after percutaneous coronary intervention have decreased since the introduction of the drug-eluting stent (DES). However, chronic kidney disease (CKD) and diabetes mellitus (DM) remain strong clinical predictors of poor prognosis despite DES implantation. Sarpogrelate, a selective serotonin (5-hydroxytryptamine (HT)2a [5-HT2A]) receptor antagonist, has antiproliferative effects, reducing neointimal hyperplasia and smooth muscle cell proliferation, as well as potent antiplatelet action, inhibiting 5-HT-induced platelet aggregation. However, efficacy and safety data for sarpogrelate in patients with CKD or DM are limited. We aim to determine whether sarpogrelate has beneficial effects in patients with CDK or DM treated with DES implantation. The SERENADE trial is a multicenter, open-label, prospective, randomized study that will test the superiority of triple anti-platelet therapy (TAT; aspirin, clopidogrel, and sarpogrelate) to conventional dual antiplatelet therapy (DAT; aspirin and clopidogrel) in preventing late lumen loss 9 months after the index procedure in patients with CKD or DM. A total of 220 patients diagnosed with coronary artery disease with DM or CKD will be randomized to the TAT or DAT groups (1:1 ratio) after DES implantation. The primary endpoint is late lumen loss at 9 months assessed by quantitative coronary angiography. Secondary efficacy endpoints are composites of major adverse cardiovascular events including cardiac death, nonfatal myocardial infarction, and target lesion revascularization. Secondary safety endpoints are major bleeding events and hepatic or renal impairment. The SERENADE trial will provide insight on the efficacy of adjunctive therapy with sarpogrelate after DES implantation for patients with high-risk profiles such as CKD or DM.

    Sodium-glucose co-transporter-2 (SGLT2) inhibitors are anti-diabetic agents that improve glycemic control with a low risk of hypoglycemia and ameliorate a variety of cardiovascular risk factors. The aim of the ongoing study described herein is to investigate the preventive effects of tofogliflozin, a potent and selective SGLT2 inhibitor, on the progression of atherosclerosis in subjects with type 2 diabetes (T2DM) using carotid intima-media thickness (IMT), an established marker of cardiovascular disease (CVD), as a marker. The Study of Using Tofogliflozin for Possible better Intervention against Atherosclerosis for type 2 diabetes patients (UTOPIA) trial is a prospective, randomized, open-label, blinded-endpoint, multicenter, and parallel-group comparative study. The aim was to recruit a total of 340 subjects with T2DM but no history of apparent CVD at 24 clinical sites and randomly allocate these to a tofogliflozin treatment group or a conventional treatment group using drugs other than SGLT2 inhibitors. As primary outcomes, changes in mean and maximum IMT of the common carotid artery during a 104-week treatment period will be measured by carotid echography. Secondary outcomes include changes in glycemic control, parameters related to β-cell function and diabetic nephropathy, the occurrence of CVD and adverse events, and biochemical measurements reflecting vascular function. This is the first study to address the effects of SGLT2 inhibitors on the progression of carotid IMT in subjects with T2DM without a history of CVD. The results will be available in the very near future, and these findings are expected to provide clinical data that will be helpful in the prevention of diabetic atherosclerosis and subsequent CVD.

However, it remains unclear whether one type of dressing is better than any other type for preventing ulcer development during surgery. Therefore, we compared the effects of ceramide 2-containing hydrocolloid dressing with film dressings in high-risk patients with regard to reducing the incidence of pressure ulcer development during surgery. Patients and methods: A prospective, randomized, open-label, clinical trial was conducted involving patients who were at a high risk of developing pressure ulcers at a Japanese hospital. The intervention group received ceramide 2-containing hydrocolloid dressings (n=66, and the control group received film dressings (n=64. The primary end point was the incidence rate of pressure ulcer development in both groups; skin damage, such as blanchable erythema, skin discoloration, contact dermatitis, and stripped skin, was recorded as the secondary end point. The relative risk (RR and 95% confidence interval (CI were assessed to compare the probability ratios of pressure ulcer development between the groups. Results: There were significantly fewer patients who developed pressure ulcers in the intervention group than in the control group (RR, 0.37; 95% CI, 0.05–0.99; P=0.04. In the post hoc subgroup analysis, the superiority of the intervention group was more marked when patients had a lower body mass index (P=0.02, lower albumin values (P=0.07, and operation time of 3 hours or more and less than 6 hours (P=0.03.

    Autologous hematopoietic stem cell transplantation (auto-HSCT) improves survival in patients with multiple myeloma (MM) and non-Hodgkin lymphoma (NHL). Traditionally, filgrastim (Neupogen; recombinant G-CSF) has been used in as a single agent or in combination with plerixafor for stem cell mobilization for auto-HSCT. In Europe, a biosimilar recombinant G-CSF (Tevagrastim) has been approved for various indications similar to those of reference filgrastim, including stem cell mobilization for auto-HSCT; however, in the United States, tbo-filgrastim (Granix) is registered under the original biological application and is not approved for stem cell mobilization. In retrospective studies, stem cell mobilization with tbo-filgrastim has shown similar efficacy and toxicity as filgrastim, but no prospective studies have been published to date. We have conducted the first prospective randomized trial comparing the safety and efficacy of tbo-filgrastim in combination with plerixafor with that of filgrastim in combination with plerixafor for stem cell mobilization in patients with MM and NHL. This is a phase 2 prospective randomized (1:1) open-label single-institution noninferiority study of tbo-filgrastim and filgrastim with plerixafor in patients with MM or NHL undergoing auto-HSCT. Here 10 µg/kg/day of tbo-filgrastim/filgrastim was administered s.c. for 5 days (days 1 to 5). On day 4 at approximately 1800 hours, 0.24 mg/kg of plerixafor was administered s.c. Apheresis was performed on day 5 with a target cumulative collection goal of at least 5.0 × 10 6 CD34 + cells/kg. The primary objective was to compare day 5 CD34 +  cells/kg collected. Secondary objectives included other mobilization endpoints, safety, engraftment outcomes, and hospital readmission rate. A total of 97 evaluable patients were enrolled (tbo-filgrastim, n = 46; filgrastim, n = 51). Tbo-filgrastim was not inferior to filgrastim in terms of day 5 CD34 +  cell collection (mean, 11.6 ± 6.7 CD34

    To evaluate the benefit-risk profile (BRP) of oxycodone/naloxone (OXN) and tapentadol (TAP) in patients with chronic low back pain (cLBP) with a neuropathic component (NC) in routine clinical practice. This was a blinded end point analysis of randomly selected 12-week routine/open-label data of the German Pain Registry on adult patients with cLBP-NC who initiated an index treatment in compliance with the current German prescribing information between 1st January and 31st October 2015 (OXN/TAP, n=128/133). Primary end point was defined as a composite of three efficacy components (≥30% improvement of pain, pain-related disability, and quality of life each at the end of observation vs baseline) and three tolerability components (normal bowel function, absence of either central nervous system side effects, and treatment-emergent adverse event [TEAE]-related treatment discontinuation during the observation period) adopted to reflect BRP assessments under real-life conditions. Demographic as well as baseline and pretreatment characteristics were comparable for the randomly selected data sets of both index groups without any indicators for critical selection biases. Treatment with OXN resulted formally in a BRP noninferior to that of TAP and showed a significantly higher primary end point response vs TAP (39.8% vs 25.6%, odds ratio: 1.93; P =0.014), due to superior analgesic effects. Between-group differences increased with stricter response definitions for all three efficacy components in favor of OXN: ≥30%/≥50%/≥70% response rates for OXN vs TAP were seen for pain intensity in 85.2%/67.2%/39.1% vs 83.5%/54.1%/15.8% ( P = ns/0.031/<0.001), for pain-related disability in 78.1%/64.8%/43.8% vs 66.9%/50.4%/24.8% ( P =0.043/0.018/0.001), and for quality of life in 76.6%/68.0%/50.0% vs 63.9%/54.1%/34.6% ( P =0.026/0.022/0.017). Overall, OXN vs TAP treatments were well tolerated, and proportions of patients who either maintained a normal bowel function (68.0% vs 72

    This randomized controlled trial was performed to investigate whether placebo effects in chronic low back pain could be harnessed ethically by adding open-label placebo (OLP) treatment to treatment as usual (TAU) for 3 weeks. Pain severity was assessed on three 0- to 10-point Numeric Rating Scales, scoring maximum pain, minimum pain, and usual pain, and a composite, primary outcome, total pain score. Our other primary outcome was back-related dysfunction, assessed on the Roland-Morris Disability Questionnaire. In an exploratory follow-up, participants on TAU received placebo pills for 3 additional weeks. We randomized 97 adults reporting persistent low back pain for more than 3 months' duration and diagnosed by a board-certified pain specialist. Eighty-three adults completed the trial. Compared to TAU, OLP elicited greater pain reduction on each of the three 0- to 10-point Numeric Rating Scales and on the 0- to 10-point composite pain scale (P Pain reduction on the composite Numeric Rating Scales was 1.5 (95% confidence interval: 1.0-2.0) in the OLP group and 0.2 (-0.3 to 0.8) in the TAU group. Open-label placebo treatment also reduced disability compared to TAU (P pain (1.5, 0.8-2.3) and disability (3.4, 2.2-4.5). Our findings suggest that OLP pills presented in a positive context may be helpful in chronic low back pain.

    Full Text Available Objectives: To evaluate the usefulness of homoeopathic intervention in Schizophrenia, in untreated cases and antipsychotic treatment resistant cases, to verify indications of medicines, and to assess relapse, if any. Materials and Methods: A prospective, non-comparative, open-label observational study was carried out from October 2005-September 2010 by CCRH at Central Research Institute (H, Kottayam, Kerala, India. Patients between 20 and 60 years of age, presenting with symptoms of Schizophrenia were screened for inclusion and exclusion criteria. The patients who were on antipsychotic drugs were allowed to continue the same along with homoeopathic medicine, the dose of antipsychotics was monitored by the Psychiatrist. The symptoms of each patient were repertorized, and medicine was initially prescribed in 30C potency after consulting Materia Medica. Patients were followed up for 12 months. Outcome of treatment was assessed with Brief Psychiatric Rating Scales (BPRS. Analysis was done using Statistical Package for the Social Sciences  SPSS Version 20.0. Results: Out of 188 enrolled patients, 17 cases did not complete the baseline information. Total 171 patients were analysed as per modified Intention to Treat Principle. Significant difference (P = 0.0001, P < 0.05 in the mean scores of BPRS, using paired t test was observed at end of the study. Sulphur, Lycopodium, Natrum muriaticum, Pulsatilla and Phosphorus were found to be the most useful medicines in treating schizophrenic patients. Conclusion: The study reflects the positive role of homoeopathic medicines in the management of patients suffering from schizophrenia as measured by BPRS.

    Background Calcineurin inhibitor–associated nephrotoxicity and other adverse events have prompted efforts to minimize/eliminate calcineurin inhibitor use in kidney transplant recipients. Methods This open-label, randomized, multinational study evaluated the effect of planned transition from tacrolimus to sirolimus on kidney function in renal allograft recipients. Patients received tacrolimus-based immunosuppression and then were randomized 3 to 5 months posttransplantation to transition to sirolimus or continue tacrolimus. The primary end point was percentage of patients with 5 mL/min per 1.73 m2 or greater improvement in estimated glomerular filtration rate from randomization to month 24. Results The on-therapy population included 195 patients (sirolimus, 86; tacrolimus, 109). No between-group difference was noted in percentage of patients with 5 mL/min per 1.73 m2 or greater estimated glomerular filtration rate improvement (sirolimus, 34%; tacrolimus, 42%; P = 0.239) at month 24. Sirolimus patients had higher rates of biopsy-confirmed acute rejection (8% vs 2%; P = 0.02), treatment discontinuation attributed to adverse events (21% vs 3%; P renal function improvement at 24 months is similar for patients with early conversion to sirolimus after kidney transplantation versus those remaining on tacrolimus.

    The purpose of this study was to evaluate the effect of neurofeedback on depressive symptoms and electrophysiological disturbances in patients with major depressive disorder. We recruited participants suffering from depression to evaluate efficacy of left prefrontal beta with alpha/theta training. An 8-week, prospective, open-label study was undertaken. Twenty participants were recruited. The treatment protocol was twice or three times a week training of beta at F3 with alpha/theta at Pz for 8 weeks. When every visit, patients were received beta training for 30 min, and then alpha/theta training for 30 min. Baseline, 4 and 8 week scores of; the Hamilton rating scale for Depression (HAM-D), the Hamilton rating scale for Anxiety (HAM-A), the Beck Depression Inventory (BDI)-II, the Beck Anxiety Inventory (BAI), Clinical global impression-severity (CGI-S), and pre- and post-treatment resting state EEGs were compared. Interhemispheric alpha power asymmetry (A score) was computed for homologous sites F3-F4. Pre- and post-training clinical assessments revealed significant improvements in HAM-D, HAM-A, BDI, and CGI-S scores. Cumulative response rates by HAM-D were 35.0 and 75.0 % at 4 and 8 weeks, respectively, corresponding cumulative remission rates by HAM-D were 15.0 and 55.0 %, respectively. No significant differences were found between pre- and post-treatment A score. Neurofeedback treatment could improve depressive symptoms significantly. In addition, anxiety symptoms and clinical illness severity decreased significantly after neurofeedback treatment. Despite its several limitations, such as, small sample size and lack of a control group, this study suggested neurofeedback has significant effects in patients with major depressive disorder.

    As a common disease in pediatrics, constipation poses a high burden to the community. In this study, we aimed to investigate the efficacy of dry cupping therapy (an Eastern traditional manipulative therapy) in children with functional constipation. One hundred and twenty children (4-18 years old) diagnosed as functional constipation according to ROME III criteria were assigned to receive a traditional dry cupping protocol on the abdominal wall for 8 minutes every other day or standard laxative therapy (Polyethylene glycol (PEG) 40% solution without electrolyte), 0.4 g/kg once daily) for 4 weeks, in an open label randomized controlled clinical trial using a parallel design with a 1:1 allocation ratio. Patients were evaluated prior to and following 2, 4, 8 and 12 weeks of the intervention commencement in terms of the ROME III criteria for functional constipation. There were no significant differences between the two arms regarding demographic and clinical basic characteristics. After two weeks of the intervention, there was a significant better result in most of the items of ROME III criteria of patients in PEG group. In contrast, after four weeks of the intervention, the result was significantly better in the cupping group. There was no significant difference in the number of patients with constipation after 4 and 8 weeks of the follow-up period. This study showed that dry cupping of the abdominal wall, as a traditional manipulative therapy, can be as effective as standard laxative therapy in children with functional constipation.

    Extracorporeal shock wave lithotripsy (ESWL) is an effective therapeutic method used to treat patients with pancreatic stones. However, the anesthesia for this procedure has been underappreciated, with minimal reports of these procedures in certain case series with general or epidural anesthesia. A cohort of 60 patients who elected to undergo ESWL in order to treat pancreatic stones for the first time were randomly selected and divided into two groups. One group of patients received target controlled infusion (TCI) of remifentanil, while the other group of patients received TCI of remifentanil plus a bolus of flurbiprofen axetil (a cyclooxygenase inhibitor) (Rem group and Rem + Flu group, n = 30 for each group). The Dixon's up-and-down method was used to calculate the half maximum effective concentration (EC50) of remifentanil. Visual analogue scales of pain, Ramsay sedation scale, hemodynamic changes, and adverse events were also recorded. The EC50 of remifentanil was calculated to be 4.0 ng/ml (95 % confidential interval: 3.84 ng/ml, 4.16 ng/ml) and 2.76 ng/ml (95 % confidential interval: 2.63 ng/ml, 2.89 ng/ml) in the Rem group and Rem + Flu group respectively (p flurbiprofen axetil provided satisfactory analgesia and sedation for ESWL of pancreatic stones with less adverse events.

    Full Text Available Abstract Background Although the connection between ascending infection and preterm birth is undisputed, research focused on finding effective treatments has been disappointing. However evidence that eradication of Candida in pregnancy may reduce the risk of preterm birth is emerging. We conducted a pilot study to assess the feasibility of conducting a large randomized controlled trial to determine whether treatment of asymptomatic candidiasis in early pregnancy reduces the incidence of preterm birth. Methods We used a prospective, randomized, open-label, blinded-endpoint (PROBE study design. Pregnant women presenting at Candida were randomized to 6-days of clotrimazole vaginal pessaries (100mg or usual care (screening result is not revealed, no treatment. The primary outcomes were the rate of asymptomatic vaginal candidiasis, participation and follow-up. The proposed primary trial outcome of spontaneous preterm birth Results Of 779 women approached, 500 (64% participated in candidiasis screening, and 98 (19.6% had asymptomatic vaginal candidiasis and were randomized to clotrimazole or usual care. Women were not inconvenienced by participation in the study, laboratory testing and medication dispensing were problem-free, and the follow-up rate was 99%. There was a tendency towards a reduction in spontaneous preterm birth among women with asymptomatic candidiasis who were treated with clotrimazole RR = 0.33, 95%CI 0.04-3.03. Conclusions A large, adequately powered, randomized trial of clotrimazole to prevent preterm birth in women with asymptomatic candidiasis is both feasible and warranted.

    Full Text Available Abstract Background: Treatment of sickle cell anemia is a challenging task and despite the well understood genetic and biochemical pathway of sickle hemoglobin, current therapy continues to be limited to the symptomatic treatment of pain, supplemental oxygen, antibiotics, red blood cell transfusions and hydroxyurea. SANGUINATE is a carbon monoxide releasing molecule and oxygen transfer agent under clinical development for the treatment of sickle cell anemia and comorbidities. Methods: An open-label randomized Phase Ib study was performed in adult sickle cell anemia patients. Two dose levels of SANGUINATE were compared to hydroxyurea in 24 homozygotes for Hb SS. Twelve subjects received either a low dose (160 mg/kg of SANGUINATE or 15 mg/kg hydroxyurea. Another 12 subjects received either a high dose (320 mg/kg of SANGUINATE or 15 mg/kg hydroxyurea. The primary endpoint was the safety of SANGUINATE versus hydroxyurea in sickle cell anemia patients. Secondary endpoints included determination of the plasma pharmacokinetics and assessment of hematologic measurements. Results: Musculoskeletal related adverse events were the most common. Transient troponin I levels increased in three patients, one of whom had an increase in tricuspid regurgitant velocity; however, no clinical signs were noted. Following an assessment of vital signs, tricuspid regurgitant velocity, electrocardiogram, serum biochemistry, hematology, urinalysis, and analysis of reported adverse events, SANGUINATE was found to be safe in stable sickle cell anemia patients. Conclusions: The clinical trial met its primary objective of demonstrating an acceptable safety profile for SANGUINATE in patients with sickle cell anemia. This trial established the safety of SANGUINATE at both dose levels and permitted its advance to Phase II trials.

    Full Text Available This study aimed to determine the optimal Foley catheter balloon volume (30-mL vs. 80-mL and the maximum time for cervical ripening (12 hours vs. 24 hours to improve vaginal delivery rate within 24 hours of induction.We conducted an open-label, randomized controlled trial in a teaching hospital in China. Women with a term singleton pregnancy, cephalic presentation, intact membrane and an unfavorable cervix (Bishop score <6 were randomly allocated, in 1:1:1:1 ratio, to receive either one of the four treatments: (1 30-mL balloon for a maximum of 12 hours, (2 30-mL balloon for a maximum of 24 hours, (3 80-mL balloon for a maximum of 12 hours, and (4 80-mL balloon for a maximum of 24 hours. The primary outcome was vaginal delivery within 24 hours. Secondary outcomes included cesarean section rate and maternal/neonatal morbidity. Data were analyzed on a per-protocol basis.Five hundred and four women were recruited and randomized (126 women in each group; nine women did not receive the assigned intervention. More women achieved vaginal delivery within 24 hours in 12-hour Foley catheter groups than in the 24-hour Foley catheter groups (30-mL/12 hours: 54.5%, 30-mL/24 hours: 33.1%, 80-mL/12 hours: 46.4%, 80-mL/24 hours: 24.0%, p < 0.001. Cesarean section rates and the incidence of chorioaminonitis were comparable among four groups. After adjustment for confounding factors, both ripening time and balloon size did not affect the proportion of women delivered vaginally within 24 hours of induction.For women with an unfavorable cervix at term, induction of labor with a Foley catheter is safe and effective. Higher balloon volume (80-mL vs. 30-mL and longer ripening time (24 hours vs. 12 hours would not shorten induction to delivery interval or reduce cesarean section rate.Chinese Clinical trial registry (ChiCTR-TRC-13003044.

    The efficacy and safety of two nifuratel dosages for the treatment of aerobic vaginitis (AV) were compared. This was a prospective open-label cohort study of patients diagnosed and treated at the Tianjin Third Central Hospital between January 2012 and December 2013. The co-presence of bacterial vaginosis (BV), vulvovaginal candidiasis (VVC), or/and trichomonal vaginitis (TV; mixed AV) was determined. Patients were randomized to nifuratel-500 (500 mg nifuratel, intravaginal, 10 days) or nifuratel-250 (250 mg nifuratel, intravaginal, 10 days), and followed-up for three to seven days after treatment completion. Primary and secondary outcomes were recovery rate and adverse events, respectively. The study included 142 patients with AV. Age was not significantly different between the groups (n = 71 each), and disease distribution was identical: 29 (40.85%) simple AV and 42 (59.15%) mixed AV (AV + BV, 42.86 %; AV + VVC, 30.95%; AV + TV, 26.19%). In patients with simple AV, the recovery rate did not differ significantly between the nifuratel-500 (26/29, 89.66%) and nifuratel-250 (22/29, 75.86%) groups. In patients with mixed AV, recovery rates were significantly higher in the nifuratel-500 than in the nifuratel-250 group (AV + BV, 88.89% vs 50.00 %; AV + VVC, 76.92 % vs 30.77 %; AV + TV, 90.91 % vs 36.36%; all P < 0.05). Only one patient (nifuratel-500) reported an adverse event (mild anaphylactic reaction). Nifuratel 500 mg showed good clinical efficacy for the treatment of AV, particularly mixed AV, and is superior to the 250 mg dosage in the treatment of mixed AV. © 2016 Japan Society of Obstetrics and Gynecology.

    Full Text Available Whether anemia and mineral bone abnormalities (chronic kidney disease–mineral bone disorder [CKD-MBD] are associated still remains to be elucidated. Both anemia and CKD-MBD have been associated with adverse cardiovascular outcome and poor quality of life. However, recent evidence suggests that use of large doses of erythropoietin-stimulating agents (ESAs to correct hemoglobin (Hb may be detrimental in CKD. The Optimal Anemia Treatment in End Stage Renal Disease (ESRD (Optimal ESRD Treatment study will assess whether lowering of parathyroid hormone (PTH is associated with a reduction in ESA consumption. The Optimal ESRD Treatment study is a pilot single-center open-label study with blinded end point (a prospective randomized open blinded end-point [PROBE] design enrolling 50 patients on maintenance dialysis. Eligible patients with intact PTH (iPTH 300-540 pg/mL and Hb 10-11.5 g/dL will be randomized 1:1 to strict PTH control (150-300 pg/mL versus standard care (PTH range 300-540 pg/mL. Available drugs for CKD-MBD and anemia treatment will be managed by the attending physician to maintain the desired levels of PTH (according to study arm allocation and Hb (10-11.5 g/dL. Echocardiographic data for cardiac structure and function as well as arterial stiffness will be assessed at study inception and completion. The Optimal ESRD Treatment study should shed light on the complicated interplay of anemia and CKD-MBD and on the feasibility of clinical trials in this domain.

    To test the effectiveness and safety of omega-3 fatty acids (Omegabrite(R) brand) in the treatment of pediatric bipolar disorder (BPD). Subjects (N=20) were outpatients of both sexes, 6 to 17 years of age, with a DSM-IV diagnosis of BPD and Young Mania Rating Scale (YMRS) score of >15 treated over an 8-week period in open-label trial with omega-3 fatty acids 1290 mg-4300 mg combined EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). Subjects experienced a statistically significant but modest 8.9+/-2.9 point reduction in the YMRS scores (baseline YMRS=28.9+/-10.1; endpoint YMRS=19.1+/-2.6, pDHA increased in treated subjects. As only 35% of these subjects had a response by the usual accepted criteria of >50% decrease on the YMRS, omega-3 fatty acids treatment was associated with a very modest improvement in manic symptoms in children with BPD.

    Background We investigated whether sirolimus-based immunosuppression improves outcomes in liver transplantation (LTx) candidates with hepatocellular carcinoma (HCC). Methods In a prospective-randomized open-label international trial, 525 LTx recipients with HCC initially receiving mammalian target of rapamycin inhibitor–free immunosuppression were randomized 4 to 6 weeks after transplantation into a group on mammalian target of rapamycin inhibitor–free immunosuppression (group A: 264 patients) or a group incorporating sirolimus (group B: 261). The primary endpoint was recurrence-free survival (RFS); intention-to-treat (ITT) analysis was conducted after 8 years. Overall survival (OS) was a secondary endpoint. Results Recurrence-free survival was 64.5% in group A and 70.2% in group B at study end, this difference was not significant (P = 0.28; hazard ratio [HR], 0.84; 95% confidence interval [95% CI], 0.62; 1.15). In a planned analysis of RFS rates at yearly intervals, group B showed better outcomes 3 years after transplantation (HR, 0.7; 95% CI, 0.48-1.00). Similarly, OS (P = 0.21; HR, 0.81; 95% CI, 0.58-1.13) was not statistically better in group B at study end, but yearly analyses showed improvement out to 5 years (HR, 0.7; 95% CI, 0.49-1.00). Interestingly, subgroup (Milan Criteria-based) analyses revealed that low-risk, rather than high-risk, patients benefited most from sirolimus; furthermore, younger recipients (age ≤60) also benefited, as well sirolimus monotherapy patients. Serious adverse event numbers were alike in groups A (860) and B (874). Conclusions Sirolimus in LTx recipients with HCC does not improve long-term RFS beyond 5 years. However, a RFS and OS benefit is evident in the first 3 to 5 years, especially in low-risk patients. This trial provides the first high-level evidence base for selecting immunosuppression in LTx recipients with HCC. PMID:26555945

    This study determined whether injection with hypertonic dextrose and morrhuate sodium (prolotherapy) using a pragmatic, clinically determined injection schedule for knee osteoarthritis (KOA) results in improved knee pain, function, and stiffness compared to baseline status. This was a prospective three-arm uncontrolled study with 1-year follow-up. The setting was outpatient. The participants were 38 adults who had at least 3 months of symptomatic KOA and who were in the control groups of a prior prolotherapy randomized controlled trial (RCT) (Prior-Control), were ineligible for the RCT (Prior-Ineligible), or were eligible but declined the RCT (Prior-Declined). The injection sessions at occurred at 1, 5, and 9 weeks with as-needed treatment at weeks 13 and 17. Extra-articular injections of 15% dextrose and 5% morrhuate sodium were done at peri-articular tendon and ligament insertions. A single intra-articular injection of 6 mL 25% dextrose was performed through an inferomedial approach. The primary outcome measure was the validated Western Ontario McMaster University Osteoarthritis Index (WOMAC). The secondary outcome measure was the Knee Pain Scale and postprocedure opioid medication use and participant satisfaction. The Prior-Declined group reported the most severe baseline WOMAC score (p=0.02). Compared to baseline status, participants in the Prior-Control group reported a score change of 12.4±3.5 points (19.5%, p=0.002). Prior-Decline and Prior-Ineligible groups improved by 19.4±7.0 (42.9%, p=0.05) and 17.8±3.9 (28.4%, p=0.008) points, respectively; 55.6% of Prior-Control, 75% of Prior-Decline, and 50% of Prior-Ineligible participants reported score improvement in excess of the 12-point minimal clinical important difference on the WOMAC measure. Postprocedure opioid medication resulted in rapid diminution of prolotherapy injection pain. Satisfaction was high and there were no adverse events.

    Objective To evaluate the efficacy and tolerability of single pulse transcranial magnetic stimulation (sTMS) for the preventive treatment of migraine. Background sTMS was originally developed for the acute treatment of migraine with aura. Open label experience has suggested a preventive benefit. The objective of this trial was to evaluate the efficacy and tolerability of sTMS for migraine prevention. Methods The eNeura SpringTMS Post-Market Observational U.S. Study of Migraine (ESPOUSE) Study was a multicenter, prospective, open label, observational study. From December 2014 to March 2016, patients with migraine (n = 263) were consented to complete a 1-month baseline headache diary followed by 3 months of treatment. The treatment protocol consisted of preventive (four pulses twice daily) and acute (three pulses repeated up to three times for each attack) treatment. Patients reported daily headache status, medication use, and device use with a monthly headache diary. The primary endpoint, mean reduction of headache days compared to baseline, was measured over the 28-day period during weeks 9 to 12. The primary endpoint was compared to a statistically-derived placebo estimate (performance goal). Secondary endpoints included: 50% responder rate, acute headache medication consumption, HIT-6, and mean reduction in total headache days from baseline of any intensity. Results Of a total of 263 consented subjects, 229 completed a baseline diary, and 220 were found to be eligible based on the number of headache days. The device was assigned to 217 subjects (Safety Data Set) and 132 were included in the intention to treat Full Analysis Set. For the primary endpoint, there was a -2.75 ± 0.40 mean reduction of headache days from baseline (9.06 days) compared to the performance goal (-0.63 days) ( p < 0.0001). The 50% responder rate of 46% (95% CI 37%, 56%) was also significantly higher ( p < 0.0001) than the performance goal (20%). There was a reduction of -2

    Recent clinical trials indicate that cannabidiol (CBD) may reduce seizure frequency in pediatric patients with certain forms of treatment-resistant epilepsy. Many of these patients experience significant impairments in quality of life (QOL) in physical, mental, and social dimensions of health. In this study, we measured the caregiver-reported Quality of Life in Childhood Epilepsy (QOLCE) in a subset of patients enrolled in a prospective, open-label clinical study of CBD. Results from caregivers of 48 patients indicated an 8.2 ± 9.9-point improvement in overall patient QOLCE (p < 0.001) following 12 weeks of CBD. Subscores with improvement included energy/fatigue, memory, control/helplessness, other cognitive functions, social interactions, behavior, and global QOL. These differences were not correlated to changes in seizure frequency or adverse events. The results suggest that CBD may have beneficial effects on patient QOL, distinct from its seizure-reducing effects; however, further studies in placebo-controlled, double-blind trials are necessary to confirm this finding.

    Statins have been shown to reduce ocular inflammation in animal models of uveitis and to prevent development of uveitis in observational studies. There have been no experimental human studies evaluating statins' efficacy and safety in uveitis. In this study, we aimed to investigate efficacy and safety of simvastatin in patients with uveitis. For this single-center, open-label, randomized study, we enrolled patients with acute non-infectious uveitis. The patients were randomized to receive 40 mg simvastatin per day for 2 months in addition to conventional treatment or conventional treatment alone. The studied outcomes were the rate of steroid-sparing control of ocular inflammation, measures of ocular inflammation, intraocular pressure, and visual acuity. Fifty patients were enrolled in the study. Twenty-five patients were randomly assigned to receive simvastatin with conventional treatment and 25 to conventional treatment alone. Simvastatin was associated with significantly higher rates of steroid-sparing ocular inflammation control, decrease in anterior chamber inflammation, and improvement in visual acuity. The treatment was well tolerated, no serious adverse effects were observed. Our findings suggest that statins may have therapeutic potential in uveitis. These results need to be confirmed in double-blind, randomized, controlled studies.

    Full Text Available Background: There is a growing trend for patients to seek the least invasive treatments with less risk of complications and downtime for facial rejuvenation. Thread embedding acupuncture has become popular as a minimally invasive treatment. However, there is little clinical evidence in the literature regarding its effects. Methods: This single-arm, prospective, open-label study recruited participants who were women aged 40–59 years, with Glogau photoaging scale III–IV. Fourteen participants received thread embedding acupuncture one time and were measured before and after 1 week from the procedure. The primary outcome was a jowl to subnasale vertical distance. The secondary outcomes were facial wrinkle distances, global esthetic improvement scale, Alexiades–Armenakas laxity scale, and patient-oriented self-assessment scale. Results: Fourteen participants underwent thread embedding acupuncture alone, and 12 participants revisited for follow-up outcome measures. For the primary outcome measure, both jowls were elevated in vertical height by 1.87 mm (left and 1.43 mm (right. Distances of both melolabial and nasolabial folds showed significant improvement. In the Alexiades–Armenakas laxity scale, each evaluator evaluated for four and nine participants by 0.5 grades improved. In the global aesthetic improvement scale, improvement was graded as 1 and 2 in nine and five cases, respectively. The most common adverse events were mild bruising, swelling, and pain. However, adverse events occurred, although mostly minor and of short duration. Conclusion: In this study, thread embedding acupuncture showed clinical potential for facial wrinkles and laxity. However, further large-scale trials with a controlled design and objective measurements are needed. Keywords: polydioxanone, rejuvenation, rhytidoplasty, skin aging, thread embedding acupuncture

    Piroxicam is a NSAID with analgesic and antipyretic properties, used for the treatment of rheumatoid diseases. The aim of this study was to evaluate the bioequivalence of two brands of piroxicam capsules (20 mg) in 24 Egyptian volunteers. The in vivo study was established according to a single-center, randomized, single-dose, laboratory-blinded, 2-period, 2-sequence, crossover study with a washout period of 3 weeks. Under fasting conditions, 24 healthy male volunteers were randomly selected to receive a single oral dose of one capsule (20 mg) of either test or reference product. Plasma samples were obtained over a 144-hour interval and analyzed for piroxicam by HPLC with UV detection. The pharmacokinetic parameters Cmax , tmax , AUC0-t , AUC0-∞ , Vd /F, Cl/F, and t1/2 were determined from plasma concentration-time profiles. The 90% confidence intervals for the ratio of log transformed values of Cmax , AUC0-t , and AUC0-∞ of the two treatments were within the acceptable range (0.8-1.25) for bioequivalence. From PK perspectives, the two piroxicam formulations were considered bioequivalent, based on the rate and extent of absorption. No adverse events occurred or were reported after a single 20-mg piroxicam and both formulations were well-tolerated. © 2014, The American College of Clinical Pharmacology.

Considering the restrictions in cross sectional design of many earlier researches, we used a clinical trial aimed at assessing sexual dysfunction by substituting Risperidone, an atypical antipsychotic drug, with Haloperidol, a typical one . "n "n "nMethod: This clinical trial was conducted on 51 patients who had been using Risperidone with a minimum dose of 2 mg/daily for at least 2 months. The patients were randomly divided into 2 groups. The first group continued taking Risperidone, whereas the second group was given Haloperidol. Sexual function prior to and after the drug substitution was assessed using a sexual questionnaire designed to assess four stages of sexual function . "nResults: Compared to those who changed their medication to Haloperidol, the patients who remained on Risperidone therapy suffered from more sexual dysfunction, especially in their tendency towards having sexual activities (P= 0.01, post menstrual sexual activity (P= 0.002, and reaching orgasm in their sexual activities (P= 0.04; however in the Haloperidol group, no significant difference was observed before and after the change in medication . "nConclusion: Although Risperidone and Haloperidol can both disturb patients'sexual function, the side effects of Risperidone are stronger. Hence toprevent the decline of medication acceptance or irregular consumption by patients which may lead to possible relapse, substitution of Risperidone withanother drug with fewer side effects on sexual activities is definitely to the advantage of the patients .

    The aim of the study was to evaluate the effect of mouth cleaning with hinokitiol-containing gel on oral malodor. An open-label, randomized, controlled trial was conducted to assess oral malodor and clinical parameters related to oral malodor before and after mouth cleaning with hinokitiol-containing gel (n = 9) or with gel not including hinokitiol (n = 9). Mouth cleaning included the teeth, gingiva, and tongue and was carried out 3 times per day for 4 weeks. Organoleptic test (OLT) scores (P = .021), levels of hydrogen sulfide (P = .008) and methyl mercaptan (P = .020), frequency of bleeding on probing, average probing pocket depth, and plaque index significantly improved in the group using hinokitiol. In contrast, only the OLT score (P = .031) significantly improved in the control group after the treatment regimen. Mouth cleaning with hinokitiol-containing gel may be effective for reduction of oral malodor. Copyright © 2013 Elsevier Inc. All rights reserved.

    Full Text Available Background: Medicinal plants are powerful health promoting nutritional agents. Among the vast library of medicinal plants Tinospora cordifolia (Willd. has been meagrely explored. It belongs to the family Menispermaceae and is a rich source of alkaloid and terpenes. It has hepatoprotective, antioxidant, immunostimulatory, hyperlipidemic, anticancer and antidiabetic properties. The stem contains berberine, palmatine, tembetarine, magnoflorine, tinosporin, tinocordifolin. The stem starch is highly nutritive and digestive. In modern medicine it is called the magical rejuvenating herb owing to its properties to cure many diseases. The stem contains higher alkaloid content than the leaves because of which it is approved for medicinal usage. With a host of phytochemical properties present in the stem, it may hold potential to manage dyslipidemia and dysglycemia, which otherwise has been proven only in pre-clinical studies. Objective: To study the impact of tinospora cordifolia stem supplementation on the glycemic and lipemic profile of subjects with diabetic dyslipidemia. Methods: Type 2 diabetics with dyslipidemia on oral hypoglycemic agents were enrolled. Baseline data on medical history, family history of lifestyle diseases, duration of diabetes diagnosis, drug profile, anthropometric data, dietary data and physical activity data was obtained along with a fasting blood sample for estimating high sensitivity C reactive protein (hs-CRP, hepatic, renal, lipid profile and glycated hemoglobin. The participants were randomized into either of the two groups; intervention group (n=29 received 250mg of encapsulated mature stem of tinospora cordifolia pre meal twice a day along with prescribed dyslipidemic agent and control group (n=30 only on dyslipidemic agents for a period of 60 days. After 60 days all the parameters were re-assessed to analyse the impact of the intervention. Results: Majority of the subjects in both the arms were in the 50-60 years age

    Green tea is known as a dietary supplement and a novel functional food worldwide. Since there are increasing preclinical evidence about efficacy of green tea for treating osteoarthritis, this study has aimed at assessing its efficacy and safety for patients with knee osteoarthritis. This is a randomized open-label active-controlled clinical trial. As many as fifty adults with osteoarthritis of knee were randomly allocated to receive the green tea extract (in dosage form of tablet) plus diclofenac tablet as "intervention group"; or: diclofenac tablet alone as "control group" for a period of four weeks. Patients were assessed at the beginning of intervention, and then 4 weeks later, in terms of pain score via visual analogue scale (VAS), and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaire's total score in addition to its 3 sub-scores. Furthermore, they were asked about any adverse effects during intervention period. Mean differences of VAS pain, total WOMAC, and WOMAC physical function scores in green tea group showed a significant reduction, compared with the control group (P = 0.038, P = 0.006, and P = 0.004, respectively). However, No significant differences between the two groups were observed, regarding mean differences of WOMAC pain and stiffness scores of the enrolled patients (P = 0.163, and P = 0.150, respectively). Additionally, only 1 patient reported gastric upset [in control group]. It seems that green tea extract might well be considered as an adjunctive treatment both for control of pain and for the betterment of knee joint physical function in adults with osteoarthritis. However, further studies of longer duration and larger sample size are needed. Copyright © 2016 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism. All rights reserved.

    The present study was designed to evaluate the bioequivalence of a newly developed sildenafil citrate tablet 50 mg (Jinge®, Test) and a marketed counterpart (Viagra®, 100 mg, Reference) in healthy adult male Chinese volunteers. This single-dose, randomized, open-label, four-period, and two-treatment self-crossover study included two parts: fasting and postprandial studies. In each part of the study, the subjects were randomly assigned to receive test or reference products (100 mg sildenafil) in a 1 : 1 ratio, and then received the alternative products, following a 1-week washout period. Plasma sildenafil concentrations were analyzed by liquid chromatography-tandem mass spectrometry. Tolerability was assessed during the entire study period. 32 healthy volunteers (aged 19 - 30) were enrolled in the study; 31 volunteers completed the fasting study, while 32 volunteers completed the postprandial study. The test formulation was bioequivalent to the marketed formulation as the 90% CIs for the ratio of geometric means of Cmax (fasting: 98.79 - 119.61%; fed: 94.47 - 119.65%), AUClast (fasting: 98.70 - 109.71%; fed: 96.39 - 112.89%), and AUC∞ (fasting: 98.45 - 108.87%; fed: 96.36 - 112.74%) were within equivalence limits (80 - 125%) under both fasting and postprandial conditions. When sildenafil was given with high-fat meals, mean Cmax was reduced by 23%, and median tmax ranged from 0.75 to 1.50 hours (p ≤ 0.05). However, both AUClast and AUC∞ were comparable between fasting and postprandial conditions. No serious adverse events were found among the subjects. This study confirmed that test and reference sildenafil citrate tablets were bioequivalent under fasting and postprandial conditions.

    To determine whether maternal vitamin D supplementation, in the vitamin D deficient mother, prevents neonatal vitamin D deficiency. Open-label randomized controlled trial. Metropolitan Melbourne, Australia, tertiary hospital routine antenatal outpatient clinic. Seventy-eight women with singleton pregnancies with vitamin D deficiency/insufficiency (serum 25-OH Vit D l) at their first antenatal appointment at 12-16-week gestation were recruited. Participants were randomized to vitamin D supplementation (2000-4000 IU cholecalciferol) orally daily until delivery or no supplementation. The primary outcome was neonatal serum 25-OH vit D concentration at delivery. The secondary outcome was maternal serum 25-OH vit D concentration at delivery. Baseline mean maternal serum 25-OH vit D concentrations were similar (P = 0·9) between treatment (32 nmol/l, 95% confidence interval 26-39 nmol/l) and control groups (33 nmol/l, 95% CI 26-39 nmol/l). Umbilical cord serum 25-OH vit D concentrations at delivery were higher (P l, 95% CI; 70-91 nmol/l) compared with neonates of control group mothers (42 nmol/l, 95% CI; 34-50 nmol/l) with a strongly positive correlation between maternal serum 25-OH Vit D and umbilical cord serum 25-OH vit D concentrations at delivery (Spearman rank correlation coefficient 0·88; P l, 95% CI; 62-81 nmol/l) compared with the control group (36 nmol/l, 95% CI; 29-42 nmol/l).

    Abnormal glutamatergic neurotransmission is implicated in the pathophysiology of autism spectrum disorder (ASD). In this study, the safety, tolerability, and efficacy of the glutamatergic N-methyl-d-aspartate (NMDA) receptor antagonist memantine (once-daily extended-release [ER]) were investigated in children with autism in a randomized, placebo-controlled, 12 week trial and a 48 week open-label extension. A total of 121 children 6-12 years of age with Diagnostic and Statistical Manual of Mental Disorders, 4th ed., Text Revision (DSM-IV-TR)-defined autistic disorder were randomized (1:1) to placebo or memantine ER for 12 weeks; 104 children entered the subsequent extension trial. Maximum memantine doses were determined by body weight and ranged from 3 to 15 mg/day. There was one serious adverse event (SAE) (affective disorder, with memantine) in the 12 week study and one SAE (lobar pneumonia) in the 48 week extension; both were deemed unrelated to treatment. Other AEs were considered mild or moderate and most were deemed not related to treatment. No clinically significant changes occurred in clinical laboratory values, vital signs, or electrocardiogram (ECG). There was no significant between-group difference on the primary efficacy outcome of caregiver/parent ratings on the Social Responsiveness Scale (SRS), although an improvement over baseline at Week 12 was observed in both groups. A trend for improvement at the end of the 48 week extension was observed. No improvements in the active group were observed on any of the secondary end-points, with one communication measure showing significant worsening with memantine compared with placebo (p = 0.02) after 12 weeks. This trial did not demonstrate clinical efficacy of memantine ER in autism; however, the tolerability and safety data were reassuring. Our results could inform future trial design in this population and may facilitate the investigation of memantine ER for other clinical applications.

    The purpose of this trial is to evaluate the clinical efficacy and cost/effectiveness of Saccharomyces boulardii compared with yogurt fluid (YF) in acute non-bloody diarrhea in children. This randomized, prospective open-label clinical trial includes 55 children (36 boys, 19 girls; mean age 21.2 ± 28.2 months). Group A (N = 28) received lyophilized S. boulardii and group B (N = 27) received YF. The duration of diarrhea was shorter with S. boulardii but the hospital stay was reduced with YF, although these differences were not significant. However, diarrhea had resolved in significantly more children on day 3 in the S. boulardii group (48.5% versus 25.5%; P < 0.05). In outpatient cases, yogurt treatment was cheaper than S. boulardii whereas in hospitalized patients, treatment cost was similar. In conclusion, the effect of daily freshly prepared YF was comparable to S. boulardii in the treatment of acute non-bloody diarrhea in children. The duration of diarrhea was shorter in the S. boulardii group, expressed as a significantly higher number of patients with normal stools on day 3. PMID:20207879

    The purpose of this trial is to evaluate the clinical efficacy and cost/effectiveness of Saccharomyces boulardii compared with yogurt fluid (YF) in acute non-bloody diarrhea in children. This randomized, prospective open-label clinical trial includes 55 children (36 boys, 19 girls; mean age 21.2 +/- 28.2 months). Group A (N = 28) received lyophilized S. boulardii and group B (N = 27) received YF. The duration of diarrhea was shorter with S. boulardii but the hospital stay was reduced with YF, although these differences were not significant. However, diarrhea had resolved in significantly more children on day 3 in the S. boulardii group (48.5% versus 25.5%; P boulardii whereas in hospitalized patients, treatment cost was similar. In conclusion, the effect of daily freshly prepared YF was comparable to S. boulardii in the treatment of acute non-bloody diarrhea in children. The duration of diarrhea was shorter in the S. boulardii group, expressed as a significantly higher number of patients with normal stools on day 3.

Methods: This pilot randomized, open-label study compared the efficacy of quetiapine versus olanzapine in reducing impulsive and aggressive behaviors (primary endpoints and psychotic symptoms (secondary endpoints from baseline to days 1, 7, 14, 28, 42, 56, and 70, in 15 violent schizophrenic patients hospitalized in a maximum-security psychiatric hospital. Results: Quetiapine (525±45 mg and olanzapine (18.5±4.8 mg were both efficacious in reducing Impulsivity Rating Scale from baseline to day 70. In addition, both treatments reduced the Brief Psychiatric Rating Scale, Positive and Negative Syndrome Scale, and Clinical Global Impression Scale scores at day 70 compared to baseline, and no differences were observed between treatments. Moreover, quetiapine, but not olanzapine, yielded an improvement of depressive symptoms in the items “depression” in Brief Psychiatric Rating Scale and “blunted affect” in Positive and Negative Syndrome Scale. Modified Overt Aggression Scale scores were also decreased from baseline to the endpoint, but due to the limited number of patients, it was not possible to detect a significant difference. Conclusion: In this pilot study, quetiapine and olanzapine equally decreased impulsive and psychotic symptoms after 8 weeks of treatment. Double-blind, large studies are needed to confirm the validity of these two treatments in highly aggressive and violent schizophrenic patients. Keywords: schizophrenia, aggression

    The Organ Care System is the only clinical platform for ex-vivo perfusion of human donor hearts. The system preserves the donor heart in a warm beating state during transport from the donor hospital to the recipient hospital. We aimed to assess the clinical outcomes of the Organ Care System compared with standard cold storage of human donor hearts for transplantation. We did this prospective, open-label, multicentre, randomised non-inferiority trial at ten heart-transplant centres in the USA and Europe. Eligible heart-transplant candidates (aged >18 years) were randomly assigned (1:1) to receive donor hearts preserved with either the Organ Care System or standard cold storage. Participants, investigators, and medical staff were not masked to group assignment. The primary endpoint was 30 day patient and graft survival, with a 10% non-inferiority margin. We did analyses in the intention-to-treat, as-treated, and per-protocol populations. This trial is registered with ClinicalTrials.gov, number NCT00855712. Between June 29, 2010, and Sept 16, 2013, we randomly assigned 130 patients to the Organ Care System group (n=67) or the standard cold storage group (n=63). 30 day patient and graft survival rates were 94% (n=63) in the Organ Care System group and 97% (n=61) in the standard cold storage group (difference 2·8%, one-sided 95% upper confidence bound 8·8; p=0·45). Eight (13%) patients in the Organ Care System group and nine (14%) patients in the standard cold storage group had cardiac-related serious adverse events. Heart transplantation using donor hearts adequately preserved with the Organ Care System or with standard cold storage yield similar short-term clinical outcomes. The metabolic assessment capability of the Organ Care System needs further study. TransMedics. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available Abstract Background In clinical practice, physicians often need to change the antipsychotic medications they give to patients because of an inadequate response or the presence of unacceptable or unsafe side effects. However, there is a lack of consensus in the field as to the optimal switching strategy for antipsychotics, especially with regards to the speed at which the dose of the previous antipsychotic should be reduced. This paper assesses the short-term results of strategies for the discontinuation of olanzapine when initiating risperidone. Methods In a 6-week, randomized, open-label, rater-blinded study, patients with schizophrenia or schizoaffective disorder, on a stable drug dose for more than 30 days at entry, who were intolerant of or exhibiting a suboptimal symptom response to more than 30 days of olanzapine treatment, were randomly assigned to the following switch strategies (common risperidone initiation scheme; varying olanzapine discontinuation: (i abrupt strategy, where olanzapine was discontinued at risperidone initiation; (ii gradual 1 strategy, where olanzapine was given at 50% entry dose for 1 week after risperidone initiation and then discontinued; or (iii gradual 2 strategy, where olanzapine was given at 100% entry dose for 1 week, then at 50% in the second week, and then discontinued. Results The study enrolled 123 patients on stable doses of olanzapine. Their mean age was 40.3 years and mean (± standard deviation (SD baseline Positive and Negative Syndrome Scale (PANSS total score of 75.6 ± 11.5. All-cause treatment discontinuation was lowest (12% in the group with the slowest olanzapine dose reduction (gradual 2 and occurred at half the discontinuation rate in the other two groups (25% in abrupt and 28% in gradual 1.

    The efficacy of both methylphenidate and atomoxetine has been established in placebo-controlled trials. The present study aimed to directly compare the efficacy of methylphenidate and atomoxetine in improving symptoms among children with attention-deficit/hyperactivity disorder (ADHD). The study sample included 160 drug-naïve children and adolescents 7-16 years of age, with DSM-IV-defined ADHD, randomly assigned to osmotic-release oral system methylphenidate (OROS-methylphenidate) (n=80) and atomoxetine (n=80) in a 24 week, open-label, head-to-head clinical trial. The primary efficacy measure was the score of the ADHD Rating Scale-IV Parents Version: Investigator Administered and Scored (ADHD-RS-IV). The secondary efficacy measures included the Clinical Global Impressions-ADHD-Severity (CGI-ADHD-S) and Chinese Swanson, Nolan, and Pelham IV scale (SNAP-IV), based on the ratings of investigators, parents, teachers, and subjects. At week 24, mean changes in ADHD-RS-IV Inattention scores were 13.58 points (Cohen's d, -3.08) for OROS-methylphenidate and 12.65 points (Cohen's d, -3.05) for atomoxetine; and mean changes in ADHD-RS-IV Hyperactivity-Impulsivity scores were 10.16 points (Cohen's d, -1.75) for OROS-methylphenidate and 10.68 points (Cohen's d, -1.87) for atomoxetine. In terms of parent-, teacher-, and self-ratings on behavioral symptoms, both of the two treatment groups significantly decreased on the SNAP-IV scores at the end-point, with effect sizes ranging from 0.9 to 0.96 on the Inattention subscale and from 0.61 to 0.8 on the Hyperactivity/Impulsivity subscale for OROS-methylphenidate; and from 0.51 to 0.88 on the Inattention subscale and from 0.29 to 0.57 on the Hyperactivity/Impulsivity subscale for atomoxetine. No statistically significant differences between treatment groups were observed on the outcome measures. Vomiting, somnolence, and dizziness were reported more often for atomoxetine than for OROS-methylphenidate, whereas insomnia was reported

    Dietary intake of fruits and vegetables has been suggested to have a role in promoting bone health. More specifically, the polyphenols they contain have been linked to physiological effects related to bone mineral density and bone metabolism. In this research, we use standard microarray analyses of peripheral whole blood from post-menopausal women treated with two fixed combinations of plant extracts standardized to polyphenol content to identify differentially expressed genes relevant to bone health. In this 28-day open-label study, healthy post-menopausal women were randomized into three groups, each receiving one of three investigational fixed combinations of plant extracts: an anti-resorptive (AR) combination of pomegranate fruit (Punica granatum L.) and grape seed (Vitis vinifera L.) extracts; a bone formation (BF) combination of quercetin (Dimorphandra mollis Benth) and licorice (Glycyrrhiza glabra L.) extracts; and a fixed combination of all four plant extracts (AR plus BF). Standard microarray analysis was performed on peripheral whole blood samples taken before and after each treatment. Annotated genes were analyzed for their association to bone health by comparison to a gene library. The AR combination down-regulated a number of genes involved in reduction of bone resorption including cathepsin G (CTSG) and tachykinin receptor 1 (TACR1). The AR combination also up-regulated genes associated with formation of extracellular matrix including heparan sulfate proteoglycan 2 (HSPG2) and hyaluronoglucosaminidase 1 (HYAL1). In contrast, treatment with the BF combination resulted in up-regulation of bone morphogenetic protein 2 (BMP-2) and COL1A1 (collagen type I α1) genes which are linked to bone and collagen formation while down-regulating genes linked to osteoclastogenesis. Treatment with a combination of all four plant extracts had a distinctly different effect on gene expression than the results of the AR and BF combinations individually. These results could

    To compare the efficacy and safety profile between intramuscular (IM) olanzapine and IM haloperidol plus IM lorazepam in acute schizophrenic patients with moderate to severe agitation. This was a prospective, randomized, open-label study. Acutely agitated patients with schizophrenia or schizoaffective disorder (n = 67) were randomized to receive 10 mg IM olanzapine (n = 37) or 5 mg IM haloperidol plus 2 mg IM lorazepam (n = 30). Agitation was measured with Positive and Negative Syndrome Scale Excited Component (PANSS-EC) and Agitation-Calmness Evaluation Scale (ACES) during the first 2 hours and at 24 hours after the first injection. Safety was assessed using the Simpson-Angus Scale and Barnes Akathisia Rating Scale and by recording adverse events at 24 hours following the first injection. The Clinical Global Impression-Severity scale was also rated. The PANSS-EC scores decreased significantly at 2 hours after the first injection in both groups (olanzapine: -10.2, p haloperidol + lorazepam: -9.9, p Haloperidol plus lorazepam was not inferior to olanzapine in reducing agitation at 2 hours. There were no significant differences in PANSS-EC or ACES scores between the two groups within 2 hours following the first injection. The frequencies of adverse events and changes in Clinical Global Impression-Severity, Simpson-Angus Scale, and Barnes Akathisia Rating Scale scores from baseline to 24 hours showed no significant differences between the groups. The findings suggest that IM haloperidol (5 mg) plus lorazepam (2 mg) is not inferior to IM olanzapine (10 mg) in the treatment of acute schizophrenic patients with moderate to severe agitation (ClinialTrials.gov identifier number NCT00797277).

    The objective of this prospective, open-label study was to determine the long-term effect of medicinal cannabis treatment on pain and functional outcomes in participants with treatment-resistant chronic pain. The primary outcome was the change in the pain symptom score on the S-TOPS (Treatment Outcomes in Pain Survey-Short Form) questionnaire at the 6-month follow-up in an intent-to-treat population. Secondary outcomes included the change in S-TOPS physical, social, and emotional disability scales, the pain severity, and pain interference on the Brief Pain Inventory, sleep problems, and the change in opioid consumption. A total of 274 participants were approved for treatment; complete baseline data were available for 206 (intent-to-treat), and complete follow-up data for 176 participants. At follow-up, the pain symptom score improved from median 83.3 (95% confidence interval [CI], 79.2-87.5) to 75.0 (95% CI, 70.8-79.2) (Pmedicinal cannabis in this open-label, prospective cohort resulted in improved pain and functional outcomes, and a significant reduction in opioid use. Results suggest long-term benefit of cannabis treatment in this group of patients, but the study's noncontrolled nature should be considered when extrapolating the results.

    Background Benign prostatic hyperplasia (BPH), a common disease in men over age 50 years, often causes bladder outlet obstruction and lower urinary tract symptoms (LUTS). Alpha blockers in combination with muscarinic receptor antagonists may have the potential to improve symptoms. This study aimed to assess the efficacy and safety of doxazosin or tamsulosin combined with tolterodine extend release (ER) in patients with BPH and LUTS. Material/Methods In a prospective, randomized, open-label study (ChiCTR-IPR-15005763), 220 consecutive men with BPH and LUTS were allocated to receive doxazosin 4 mg and tolterodine ER 4 mg per day (doxazosin group) or tamsulosin 0.2 mg and tolterodine ER 4 mg per day (tamsulosin group). Treatment lasted 12 weeks. The primary endpoint was the international prostatic symptom score (IPSS). Secondary endpoints were quality of life (QoL) and maximum flow rate (Qmax), which were evaluated at 0, 6, and 12 weeks, and urodynamic parameters assessed at 0 and 12 weeks. Results A total of 192 patients completed the trial. Baseline measurements showed no differences between the groups. After 6 weeks, IPSS improved in both groups and QoL was significantly better in the doxazosin group (P=0.01). After 12 weeks, Qmax, IPSS, QoL, intravesical pressure (Pves), and bladder compliance (BC) in the doxazosin group were significantly better than in the tamsulosin group (P=0.03, P<0.001, P<0.001, P=0.027, and P=0.044, respectively). Conclusions Administration of alpha blockers combined with muscarinic receptor blocker for 12 weeks improved LUTS in men with BPH. PMID:27260129

    To evaluate the association of prostate biopsy with voiding impairment and to investigate whether tamsulosin treatment given before prostate biopsy could improve voiding dysfunction after the procedure. The study included 88 consecutive patients who underwent transrectal ultrasound-guided prostate biopsy without prior BPH medication and were prospectively randomized. Of these 88 patients, 44 patients underwent prostate biopsy only without tamsulosin treatment and served as the control group. The remaining 44 patients were treated with tamsulosin (0.2 mg daily) beginning the day before the biopsy procedure for 7 days. The International Prostate Symptom Score (IPSS) was recorded in all patients before the procedure and on postbiopsy day 7. Maximal flow rate (Q(max)) and postvoid residual urine volume were recorded in all patients before the procedure and on postbiopsy days 1 and 7. No difference was found in baseline characteristics between the two groups. The IPSS (total, storage, and voiding symptom) was not significantly changed after biopsy in both groups. In the control group, the postvoid residual urine volume was increased on postbiopsy days 1 (P tamsulosin group, Q(max) was significantly increased on postbiopsy days 1 and 7 (P tamsulosin group, but it developed in two patients (4.5%) of the control group. The results of our study show that prostate biopsy leads to objective voiding impairment. Therefore, the use of alpha-1 blocker tamsulosin before biopsy in patients without prior BPH medication may decrease this morbidity.

    Skin aging is accelerated by multiple extrinsic factors: ultraviolet radiation, smoking and pollution increase oxidative activity, damaging cellular and extracellular components such as DNA, proteins, and lipids. With age, collagen and hyaluronic acid levels decline, resulting in loss of elasticity and moisture of the skin. Over time this damage leads to characteristic signs that make the skin look older: altered facial contour, sagging skin, wrinkles, and an uneven complexion. This study evaluated the anti-aging effects of a new facial cream formulated with carnosine, Alteromonas ferment extract, crosspolymer hyaluronic acid, and a tripeptide. An open-label intra-individual study to assess the anti-aging efficacy of the investigational product in 33 women aged 45 to 65 years. The product was applied twice daily for 56 days. Facial contour and skin deformation, elasticity, hydration, and complexion were measured with specialized equipment at baseline and days 28 and 56. Additionally, subjects completed questionnaires at days 28 and 56 on the perceived efficacy and cosmetic characteristics of the product. After 56 days of use of the investigational product, a redefining effect was observed, with a significant decrease in sagging jawline (7%). Skin was significantly more hydrated (12%), firmer (29%), and more elastic (20%) ( P <0.001 for all). On complexion assessment, skin texture (a measure of skin smoothness) and spots (brown and red skin lesions) also improved significantly (12% and 6% decrease, respectively). In the subjective self-evaluation, the majority of subjects reported that the skin was visibly tightened and more elastic, flexible, and moisturized (91%, 88%, 91%, and 90%, respectively). The product was well tolerated with no adverse events reported during the study. This new cosmetic product demonstrated anti-aging effects after 56 days of use, most notably a redefined facial contour and improved complexion. It is a safe and effective anti-aging product.

    Up to 30% of patients with cutaneous lupus erythematosus (CLE) fail to respond to hydroxychloroquine (HCQ). We sought to evaluate the efficacy of increased daily doses of HCQ on cutaneous response in refractory CLE. We conducted an open-label prospective study between 2010 and 2014. Patients with CLE and HCQ blood level less than or equal to 750 ng/mL were included. The daily dose of HCQ was increased to reach blood concentrations greater than 750 ng/mL. The primary end point was the number of responders defined by an improvement of CLE Disease Area and Severity Index score (4 points or 20% decrease) in patients with HCQ blood concentration greater than 750 ng/mL. We included 34 patients (26 women; median age 45 [range 28-72] years). Two nonadherent patients were excluded. The median CLE Disease Area and Severity Index score before treatment was significantly improved after treatment (8 [range 2-30] vs 1.5 [range 0-30]), P < .001). The primary response criterion was reached in 26 (81%) of the 32 patients analyzed. A decrease in HCQ doses without further CLE flare (median follow-up 15.8 [range 3.06-77.4] months) was achieved in 15 of the 26 responders. The main limitations of the study are its open-label design and the limited number of patients included. Increasing HCQ doses to reach blood concentrations greater than 750 ng/mL should be considered before addition of other treatments in refractory CLE.

    Chinese herbal medicine Qing-Dai (also known as indigo naturalis) has been used to treat various inflammatory conditions. However, not much has been studied about the use of oral Qing-Dai in the treatment for ulcerative colitis (UC) patients. Studies exploring alternative treatments for UC are of considerable interest. In this study, we aimed at prospectively evaluating the safety and efficacy of Qing-Dai for UC patients. The open-label, prospective pilot study was conducted at Keio University Hospital. A total of 20 patients with moderate UC activity were enrolled. Oral Qing-Dai in capsule form was taken twice a day (daily dose, 2 g) for 8 weeks. At week 8, the rates of clinical response, clinical remission, and mucosal healing were 72, 33, and 61%, respectively. The clinical and endoscopic scores, CRP levels, and fecal occult blood results were also significantly improved. We observed 2 patients with mild liver dysfunction; 1 patient discontinued due to infectious colitis and 1 patient discontinued due to mild nausea. This is the first prospective study indicating that oral Qing-Dai is effective for inducing remission in patients with moderate UC activity and can be tolerated. Thus, Qing-Dai may be considered an alternative treatment for patients, although further investigation is warranted. © 2016 S. Karger AG, Basel.

    Post-stroke pneumonia is associated with increased mortality and poor functional outcomes. This study assessed the effectiveness of antibiotic prophylaxis for reducing pneumonia in patients with dysphagia after acute stroke. We did a prospective, multicentre, cluster-randomised, open-label controlled trial with masked endpoint assessment of patients older than 18 years with dysphagia after new stroke recruited from 48 stroke units in the UK, accredited and included in the UK National Stroke Audit. We excluded patients with contraindications to antibiotics, pre-existing dysphagia, or known infections, or who were not expected to survive beyond 14 days. We randomly assigned the units (1:1) by computer to give either prophylactic antibiotics for 7 days plus standard stroke unit care or standard stroke unit care only to patients clustered in the units within 48 h of stroke onset. We did the randomisation with minimisation to stratify for number of admissions and access to specialist care. Patient and staff who did the assessments and analyses were masked to stroke unit allocation. The primary outcome was post-stroke pneumonia in the first 14 days, assessed with both a criteria-based, hierarchical algorithm and by physician diagnosis in the intention-to-treat population. Safety was also analysed by intention to treat. This trial is closed to new participants and is registered with isrctn.com, number ISRCTN37118456. Between April 21, 2008, and May 17, 2014, we randomly assigned 48 stroke units (and 1224 patients clustered within the units) to the two treatment groups: 24 to antibiotics and 24 to standard care alone (control). 11 units and seven patients withdrew after randomisation before 14 days, leaving 1217 patients in 37 units for the intention-to-treat analysis (615 patients in the antibiotics group, 602 in control). Prophylactic antibiotics did not affect the incidence of algorithm-defined post-stroke pneumonia (71 [13%] of 564 patients in antibiotics group vs 52

    Initial reports of immunotherapy using intralesional Mycobacterium w (Mw) vaccine have documented its useful role in treatment of genital and extragenital warts. To compare the efficacy and safety of intralesional Mw vaccine versus cryotherapy in the treatment of refractory extragenital warts. This was a prospective, randomized, comparative study of 66 patients. The outcome was assessed in terms of complete clearance of warts and change in Dermatology Life Quality Index (DLQI) score. Complete clearance of treated warts was seen in 66.7% (20/30) and 65.5% (19/29) of patients in the Mw and cryotherapy groups, respectively (P = .769). Clearance of distant warts was significantly (P = .004) high in the Mw group. Improvement in DLQI was greater in the Mw group. Both treatment modalities were well tolerated, and no major side effects occurred. Mw vaccine and cryotherapy are equally efficacious in treatment of refractory extragenital warts. Mw vaccine has an added advantage of clearance of distant warts. © The Author(s) 2015.

    Objective: To compare the efficacy and safety of topiramate with gabapentin in the prophylaxis of migraine patients. Methods: A 12-week randomised open label control trial was conducted at the Department of Pharmacology and Therapeutics, Basic Medical Sciences Institute, Jinnah Postgraduate Medical Centre (JPMC), Karachi from January to March 2011 involving 80 outpatients who had a history of migraine. The sample was divided into two equal groups. Primary efficacy measure was changed into mean monthly migraine frequency. Secondary efficacy measure included reduction in severity and average duration of an attack. Chi square test and paired t-test were used to analyse the data through SPSS 15. Result: Reduction in mean monthly migraine frequency (10.67+-4.25 to 1.82+-2.02) in the topiramate group was significantly greater compared with (11.97+-4.452 to 2.73+-2.59) that in the gabapentin group (p<0.001). Reduction in severity from 6.60+-2.122 to 1.03+-0.92 in the topiramate group was also significantly greater compared with 6.93+-1.90 to 1.18+-1.01 in the gabapentin group (p<0.001). Reduction in the average duration of attacks from 25.77+-22.32 hours to 1.0 1.06 hours in the topiramate group was significantly greater compared with 22.20+-20.72 to 1.08+-1.40 hours in the gabapentin group (p<0.001). Weight loss and numbness were common adverse effects in the topiramate group. Dizziness, weight gain and somnolence were reported in the gabapentin group. Conclusion: Gabapentin appeared well tolerated in 30(75%) patients compared to topiramate in 23(57.5%) patients. Both drugs were equally effective in migraine prophylaxis. (author)

    Full Text Available Abstract Background Molecular hydrogen has prominent effects on more than 30 animal models especially of oxidative stress-mediated diseases and inflammatory diseases. In addition, hydrogen effects on humans have been reported in diabetes mellitus type 2, hemodialysis, metabolic syndrome, radiotherapy for liver cancer, and brain stem infarction. Hydrogen effects are ascribed to specific radical-scavenging activities that eliminate hydroxyl radical and peroxynitrite, and also to signal-modulating activities, but the detailed molecular mechanisms still remain elusive. Hydrogen is a safe molecule that is largely produced by intestinal bacteria in rodents and humans, and no adverse effects have been documented. Methods We performed open-label trial of drinking 1.0 liter per day of hydrogen-enriched water for 12 weeks in five patients with progressive muscular dystrophy (PMD, four patients with polymyositis/dermatomyositis (PM/DM, and five patients with mitochondrial myopathies (MM, and measured 18 serum parameters as well as urinary 8-isoprostane every 4 weeks. We next conducted randomized, double-blind, placebo-controlled, crossover trial of 0.5 liter per day of hydrogen-enriched water or placebo water for 8 weeks in 10 patients with DM and 12 patients with MM, and measured 18 serum parameters every 4 weeks. Results In the open-label trial, no objective improvement or worsening of clinical symptoms was observed. We, however, observed significant effects in lactate-to-pyruvate ratios in PMD and MM, fasting blood glucose in PMD, serum matrix metalloproteinase-3 (MMP3 in PM/DM, and serum triglycerides in PM/DM. In the double-blind trial, no objective clinical effects were observed, but a significant improvement was detected in lactate in MM. Lactate-to-pyruvate ratios in MM and MMP3 in DM also exhibited favorable responses but without statistical significance. No adverse effect was observed in either trial except for hypoglycemic episodes in an insulin

    To assess the efficacy of bisphosphonate therapy on bone pain in patients with osteoid osteoma (OO) (main objective), and to describe bisphosphonate-induced changes in nidus mineralisation and regional bone-marrow oedema (BMO). A prospective, observational study was conducted from 2011 to 2014. Patients with risk factors for complications of percutaneous or surgical ablation or recurrence after ablation, were offered once monthly intravenous bisphosphonate treatment until significant pain alleviation was achieved. We included 23 patients. The first two patients received pamidronate and the next 21 zoledronic acid (mean, 2.95 infusions per patient). Bisphosphonate therapy was successful in 19 patients (83%), whose mean pain visual analogue scale score decreased by 76.7%; this pain-relieving effect persisted in 17 patients (74%) with a mean follow-up time of 36 months. Computed tomography (CT) demonstrated a mean nidus density increase of 177.7% (p = 0.001). By magnetic resonance imaging (MRI), mean decreases were 38.4% for BMO surface area and 30.3% for signal intensity (p = 0.001 and p = 0.000, respectively). In 17/23 patients with painful OO managed conservatively with bisphosphonates, long-term final success was achieved. Bisphosphonates may accelerate the spontaneous healing of OO. (orig.)

    Background: Total skin electron beam therapy (TSEBT) is a powerful treatment for cutaneous T-cell lymphomas (CTCL). Based on the occurrence of relapses with low radiation doses, doses of 30-36 Gy are commonly used but most patients still eventually relapse and repeat treatment courses are limited...... due to the cumulative toxicity. Complete response rates are about 60-90% for T2-4 stages with a 5-year relapse-free survival of 10-25% for stages IB-III. Objectives: To evaluate prospectively the efficacy of low-dose TSEBT (10 Gy) in terms of complete cutaneous response rate, overall response rate...... and response duration in CTCL. Methods: Ten patients with stage IB-IV mycosis fungoides (MF) were treated in an open-label manner with 4 fractions of 1 Gy/week TSEB to a total skin dose of 10 Gy. Treatment responses were assessed at 1 and 3 months after treatment and subsequently at least every 6 months...

    To investigate the long-term weight loss outcomes during usual clinical practice after switching from olanzapine standard oral tablet (SOT) to olanzapine orally disintegrating tablets (ODT). In this open-label prospective study, 26 patients with schizophrenia who were clinically stable on olanzapine SOT treatment were switched to olanzapine ODT. All other aspects of treatment remained constant. Weight was recorded at 3, 6, and 12 months. Patients incurred an average weight loss of 2.7 +/- 0.7 kg (p = 0.001) after switching patients from olanzapine SOT to olanzapine ODT at 12 months. Peak weight loss was observed at 6 months; however, significant weight loss was achieved as early as 3 months. The majority (81.9%) of patients lost weight, while 18.1% had no weight change or weight gain. Body mass index (BMI) significantly decreased by 1.0 +/- 0.3 kg/m(2) (p = 0.001). Interestingly, patients treated with higher doses of olanzapine (> or = 20 mg) incurred a greater weight loss of their body weight (5.6%), compared to those treated with lower doses (< 20 mg), who lost 1.9% of their body weight (p = 0.04). This study demonstrated that, in usual clinical practice, switching patients from olanzapine SOT to olanzapine ODT treatment resulted in significant weight loss that was maintained over 12 months. 2008 John Wiley & Sons, Ltd.

    To evaluate the efficacy and safety of itopride used to treat the symptoms of functional dyspepsia (FD) of the upper gastrointestinal tract. A prospective, open-label, multicenter trial using as a control the placebo response obtained in the previous investigations enrolled 96 adult patients. The diagnosis of FD corresponded to its Rome II criteria. Patients received itopride (Ganaton) oral tablets (50 mg) 3 times daily for 8 weeks. When included into the trial, the patients were orally given itopride (ganaton) tablets (50 mg) thrice daily before meals for 8 weeks. The patients' status was evaluated during (at weeks 4 and 8) and after (at week 12) treatment. Treatment response was assessed using the Global Patient Assessment (GPA) and the Leeds Dyspepsia Questionnaire (LDQ). To evaluate the safety of itopride use, the investigators studied the frequency of adverse events and carried out laboratory tests (renal and liver function tests) and electrocardiography (ECG). The GPA showed that 53.76, 85.71, and 82.22% of the patients achieved a therapeutic effect of itopride at weeks 4, 8, and 12, respectively. The proportion of the patients who achieved the therapeutic effect (86%) at week 8 was higher than the historical placebo controls in the previous studies--45% (86% vs 45%; X2 = 68.868, df = 3; p Itopride is an effective and well-tolerated drug in the treatment of functional dyspepsia in the Russian patients.

    Action observation treatment has been proposed as therapeutic option in rehabilitation of patients affected by Parkinson's disease (PD) to improve freezing of gait episodes. The purpose of this prospective open-label feasibility study was to evaluate the impact of 8-week action observation training (video-therapy) for the treatment of postural instability and balance impairment in PD patients. Fifteen PD patients aged under 80 years with scores of 1 to 3 on the Hoehn and Yahr staging and without evidence of freezing of gait were recruited. They underwent 24 sessions of video-therapy training based on carefully watching video clips on motor tasks linked to balance, subsequently performing the same observed movements. No statistically significant differences were observed in the identified outcome measures with the Berg Balance Scale and the Activities-Specific Balance Confidence Scale after two months of follow-up. In the present study, a short course of action observation treatment seems to be not effective in reducing balance impairments and postural instability in patients affected by mild to moderate PD. Further studies with larger samples, longer follow-up period, and standardized protocols of action observation treatment are needed to investigate the effects of this rehabilitation technique in the management of postural and balance disorders of PD patients.

    Metabolic syndrome (MetS) is prevalent in subjects with schizophrenia-related psychotic disorders and contributes to increased rates of premature death due to cardiovascular disease. This study examined the impact of switching from another antipsychotic to ziprasidone on the distribution of the number of risk factors for MetS in subjects with schizophrenia or related psychotic disorders. In this 1 year, open-label, prospective study, all subjects received ziprasidone 40-160 mg/day. Standard exclusion criteria included treatment resistance, physical health disorders, and substance abuse. The primary end point was the percentage of subjects achieving a reduction from baseline of at least one risk factor for MetS at end point (week 52 or premature discontinuation) in the per-protocol population (treated for at least 16 weeks). Secondary end points included the mean change from baseline in number of MetS risk factors, the prevalence of MetS, individual MetS risk factors (waist circumference, blood pressure, fasting triglycerides, high-density lipoprotein cholesterol, and glucose), and 10 year coronary heart disease (Framingham score) risk. www.clinicaltrials.gov: NCT00748566. Of 114 evaluable subjects, 58.77% demonstrated one less MetS risk factor at week 52 (last observation carried forward) compared with baseline. Secondary end points also improved, with reductions in other metabolic parameters (fasting low-density lipoprotein cholesterol, total cholesterol and serum insulin, weight, body mass index and glycosylated hemoglobin [HbA1c]). The 10 year coronary heart disease risk decreased continually over time. The open-label and uncontrolled design is a limitation of the study. Ziprasidone treatment reduced both the rate of MetS and its individual risk factors in subjects with schizophrenia and related psychotic disorders. The results have implications for the selection of first-line treatments in schizophrenia and related psychotic disorders, and provide treatment

    Background Attention deficit hyperactivity disorder (ADHD) is one of the most common mental disorders during childhood,characterized by the core symptoms of hyperactivity,impulsivity and inattention and puts great burden on children themselves,their families and the society.Osmotic release oral system methylphenidate (OROS-MPH) is a once-daily controlled-release formulation developed to overcome some of the limitations associated with immediate-release methylphenidate (IR-MPH).It has been marketed in China since 2005 but still lacks data from large-sample clinical trials on efficacy and safety profiles.The aim of this study was to evaluate the effectiveness and safety of OROS-MPH in children aged 6 to 16 years with ADHD under naturalistic clinical setting.Methods This 6-week,multi-center,prospective,open-label study enrolled 1447 ADHD children to once-daily OROS-MPH (18 mg,36 mg or 54 mg) treatment.The effectiveness measures were parent-rated Inattention and Overactivity With Aggression (IOWA) Conners I/O and O/D subscales,physician-rated CGI-I and parent-rated global efficacy assessment scale.Blood pressure,pulse rate measurement,adverse events (AEs) and concomitant medications and treatment review were conducted by the investigator and were served as safety measures.Results A total of 1447 children with ADHD (mean age (9.52±2.36) years) were enrolled in this trial.Totally 96.8%children received an OROS-MPH modal dose of 18 mg,3.1% with 36 mg and 0.1% with 54 mg at the endpoint of study.The parent IOWA Conners I/O score at the end of week 2 showed statistically significant (P <0.001) improvement with OROS-MPH (mean:6.95±2.71) versus the score at baseline (10.45±2.72).The change in the parent IOWA Conners O/D subscale,CGI-I and parent-rated global efficacy assessment scale also supported the superior efficacy for OROS-MPH treatment.Fewer than half of 1447 patients (511 (35.3%)) reported AEs,and the majority of the events reported were mild (68.2

    In recent years a series of trials has sought to define the optimal protocol for everolimus-based immunosuppression in heart transplantation, with the goal of minimizing exposure to calcineurin inhibitors (CNIs) and harnessing the non-immunosuppressive benefits of everolimus. Randomized studies have demonstrated that immunosuppressive potency can be maintained in heart transplant patients receiving everolimus despite marked CNI reduction, although very early CNI withdrawal may be inadvisable. A potential renal advantage has been shown for everolimus, but the optimal time for conversion and the adequate reduction in CNI exposure remain to be defined. Other reasons for use of everolimus include a substantial reduction in the risk of cytomegalovirus infection, and evidence for inhibition of cardiac allograft vasculopathy, a major cause of graft loss. The ongoing MANDELA study is a 12-month multicenter, randomized, open-label, parallel-group study in which efficacy, renal function and safety are compared in approximately 200 heart transplant patients. Patients receive CNI therapy, steroids and everolimus or mycophenolic acid during months 3 to 6 post-transplant, and are then randomized at month 6 post-transplant (i) to convert to CNI-free immunosuppression with everolimus and mycophenolic acid or (ii) to continue reduced-exposure CNI, with concomitant everolimus. Patients are then followed to month 18 post-transplant The rationale and expectations for the trial and its methodology are described herein. Copyright © 2015 Elsevier Inc. All rights reserved.

    Migraine headaches are the most common acute and recurrent headaches. Current treatment of a migraine headache consists of multiple medications for control and prevention of recurrent attacks. Global emergence of alternative medicine led us to examine the efficacy of cupping therapy plus serkangabin syrup in the treatment of migraine headaches. This study was a randomized, controlled, open-label, comparative efficacy trial. We randomly assigned patients with migraine into cupping therapy plus serkangabin group (30 patients) and conventional treatment group (30 patients). An investigator assessed the severity of headache, frequency of attacks in a week and duration of attacks per hour in 5 visits (at the end of 2 weeks, 1, 3 and 6 months). Generalized estimating equations approach was used to analyze repeated measures data to compare outcomes in both groups. Average age for cupping therapy group and conventional treatment group were 31.7 (±7.6) and 32.6 (±12.7) years, respectively (P = 0.45). After treatment for 2 weeks; and 1, 3 and 6 months, severity of headache (P = 0.80), frequency of migraine attacks (P = 0.63) and duration of attacks per hours (P = 0.48) were similar in conventional and cupping groups but these symptoms were decreased in each group during the study (P cupping plus serkangabin therapy and conventional treatment in the treatment and prophylaxis of migraine. The alternative therapy may be used in cases of drug intolerance, no medication response, and in primary care.

    Full Text Available To prevent or combat infection, increasing the effectiveness of the immune response is highly desirable, especially in case of compromised immune system function. However, immunostimulatory therapies are scarce, expensive, and often have unwanted side-effects. β-glucans have been shown to exert immunostimulatory effects in vitro and in vivo in experimental animal models. Oral β-glucan is inexpensive and well-tolerated, and therefore may represent a promising immunostimulatory compound for human use.We performed a randomized open-label intervention pilot-study in 15 healthy male volunteers. Subjects were randomized to either the β -glucan (n = 10 or the control group (n = 5. Subjects in the β-glucan group ingested β-glucan 1000 mg once daily for 7 days. Blood was sampled at various time-points to determine β-glucan serum levels, perform ex vivo stimulation of leukocytes, and analyze microbicidal activity.β-glucan was barely detectable in serum of volunteers at all time-points. Furthermore, neither cytokine production nor microbicidal activity of leukocytes were affected by orally administered β-glucan.The present study does not support the use of oral β-glucan to enhance innate immune responses in humans.ClinicalTrials.gov NCT01727895.

    Full Text Available Background: Soymilk fermented by lactobacilli and/or bifidobacteria is attracting attention due to the excellent bioavailability of its isoflavones. We investigated the effects of fermented soymilk containing high amounts of isoflavone aglycones on facial wrinkles and urinary isoflavones in postmenopausal women in a randomized, parallel-group, open-label trial. Healthy Japanese women were randomly divided into active (n = 44, mean age 56.3 ± 0.5 or control (n = 44, mean age 56.1 ± 0.5 groups, who consumed or did not consume a bottle of soymilk fermented by Bifidobacterium breve strain Yakult and Lactobacillus mali for 8 weeks. Maximum depth of wrinkles around the crow’s feet area and other wrinkle parameters were evaluated as primary and secondary endpoints respectively at weeks 0, 4, and 8 during the consumption period. Urinary isoflavone levels were determined by liquid chromatography-mass spectrometry. Results: The active group demonstrated significant improvements in the maximum depth (p=0.015 and average depth (p=0.04 of wrinkles, and significantly elevated urinary isoflavones (daidzein, genistein, and glycitein; each p < 0.001 compared with the control during the consumption period. No serious adverse effects were recorded. Conclusion: These findings suggest that fermented soymilk taken daily may improve facial wrinkles and elevate urinary isoflavones in healthy postmenopausal women.

To compare lipid-lowering efficacy of rosuvastatin with atorvastatin. Methodology. This open-label randomized controlled trial was carried out at 1 Mountain Medical Battalion from September 2012 to August 2013 on patients with type 2 diabetes, hypertension, myocardial infarction, or stroke, meriting treatment with a statin. Those with secondary causes of dyslipidemia were excluded. Blood samples for estimation of serum total cholesterol, triglycerides, HDL-C, and LDL-C were collected after a 12-hour fast. Patients were randomly allocated to receive either atorvastatin 10 mg HS or rosuvastatin 5 mg HS daily. Lipid levels were rechecked after six weeks. Results. Atorvastatin was used in 63 patients and rosuvastatin in 66. There was a greater absolute and percent reduction in serum LDL-C levels with rosuvastatin as compared to atorvastatin (0.96 versus 0.54 mg/dL; P=0.011 and 24.34 versus 13.66%; P=0.045, whereas reduction in all other fractions was equal. Myalgias were seen in 5 (7.94% patients treated with atorvastatin and 8 (12.12% patients treated with rosuvastatin (P: 0.432. Conclusion. Rosuvastatin produces a greater reduction in serum LDL-C levels and should therefore be preferred over atorvastatin.

    To evaluate the effectiveness of OROS® hydromorphone in reducing breakthrough pain (BTP) medication frequency in Korean patients with chronic cancer pain. Multicenter, prospective, open-label, phase IV study. Patients with chronic malignant pain using immediate-release oxycodone more than two times per day for BTP. Patients were stabilized on their ongoing drug for 3 days immediately before baseline measurements (day 0). Medication was changed to OROS® hydromorphone at a dose equianalgesic to oxycodone using a 2.5:1 controlled-release oxycodone to hydromorphone hydrochloride conversion ratio; the patients were observed for 7 days. Dose was titrated, if required, and the patients were observed for another 7 days. Effectiveness and safety parameters were measured at baseline, day 7, and day 14. BTP medication frequency on days 7 and 14, compared to baseline. Of the 141 patients screened, 114 received study drug and 98 completed the study. Compared to day 0, daily BTP medication frequency on day 14 decreased from 2.93 to 2.00 (p > 0.0001), daily BTP frequency decreased from 3.67 to 2.44 (p > 0.0001), and end-of-dose pain frequency decreased by 44 percent. Pain was controlled adequately during daytime and night-time. Pain intensity decreased by 11 percent as assessed using the Korean Brief Pain Inventory and by 17 percent as assessed using the numerical rating scale. About 61.2 percent patients and 60.2 percent physicians were satisfied with the treatment. Common adverse events, which occurred in 91.2 percent patients, were constipation, somnolence, and dizziness. Once-daily OROS® hydromorphone is efficient in the reduction of cancer pain-related BTP episodes, including end-of-dose pain.

    Herbal medicine containing Vitex agnus-castus (VAC) extract is widely used by women with premenstrual syndrome (PMS) in Europe, however, in Japan, clinical evidence remains to be determined. This study attempted to investigate the efficacy and safety profiles of VAC extract in Japanese patients with PMS. A multi-center, prospective, open-label, single-arm, phase 3 study was performed in Japanese women with PMS and aged 18-44 years. The patients received Prefemin® (Max Zeller Söhne AG, Romanshorn, Switzerland), containing 20 mg of VAC extract, once daily for three menstrual cycles. The efficacy profile was examined based on the intensity of ten PMS symptoms-irritability, depressed mood, anger, headache, bloating, breast fullness, skin disorder, fatigue, drowsiness, and sleeplessness-recorded by patients via a visual analog scale (VAS). In addition, the responder rate was calculated based on the total VAS score defined by the sum of the VAS scores of the first six symptoms mentioned above. Furthermore, physician's global assessment (PGA) scores were recorded. Adverse events including vital signs and laboratory test values were monitored as safety evaluation. Sixty-nine patients received Prefemin®. After the first menstrual cycle, a statistically significant decrease in total VAS score was observed (P<0.001), and the score continued to diminish for the following two cycles. Each of the ten symptom scores decreased significantly in this manner. In addition, the responder rate increased in a time-dependent manner; the rate at the third menstrual cycle was 91.0%, and almost all of the patients were without symptoms or exhibited only mild symptoms based on PGA. Eight patients exhibited non-serious adverse events, one of which was allergic dermatitis whose causal relationship with VAC was not ruled out. VAC extract improved PMS symptoms in Japanese patients, with no substantial adverse events. This is the first study to report the effect of VAC extract in Japanese

    Pulmonary artery hypertension (PAH) remains the leading cause of morbidity and mortality in systemic sclerosis, while Raynaud's phenomenon and digital ulcers significantly add to the morbidity in systemic sclerosis (SSc). This study was undertaken to evaluate the role of sildenafil in PAH, Raynaud's phenomenon, and digital ulcers in systemic sclerosis patients. A prospective, open-label, uncontrolled pilot study was done at a tertiary care centre in India to study the safety and efficacy of oral sildenafil in PAH, Raynaud's phenomenon, digital infarcts, and ulcers in SSc. Seventeen patients fulfilling ACR classification criteria for scleroderma and having PAH were recruited. Six-minute walk test, WHO class of dyspnoea, severity of Raynaud's phenomenon, and 2D ECHO were performed in all the study subjects at baseline and at 3 months post-treatment. All patients were treated with oral sildenafil 25 mg three times a day for a period of 3 months. The pre- and post-treatment values of mean pulmonary artery pressure (PAP), 6-min walk test, WHO class of dyspnoea, and severity of Raynaud's phenomenon were compared to look for any significant change. Sixteen patients who completed 3-month follow-up had shown statistically significant improvement in 6-min walk test, WHO class of dyspnoea, severity of Raynaud's phenomenon, and mPAP. Also, there was no occurrence of new digital infarcts or ulcers, and existing ulcers showed signs of healing. Sildenafil is highly efficacious cheaper and safe alternative to other available therapies for SSc-associated PAH, Raynaud's phenomenon, and digital infarcts/ulcers.

    The HELIOS (Health Economics with Lucentis in Observational Settings) study was designed on request of the Dutch Health Authority for an observational study to assess the effectiveness and safety of ranibizumab for neovascular age-related macular degeneration (wet AMD) in daily practice. The HELIOS study was a 2-year prospective, observational, open-label, multicentre study involving 14 sites. Patients with wet AMD were enrolled and observed for a period of 24 months. The data were collected at baseline and at the visits closest around the time-points 3, 6, 12, 18 and 24 months after inclusion. Treatment with ranibizumab resulted in prevention of vision loss. The mean ETDRS score increased from 45.1 letters at baseline to 48.5 letters at 24 months. This was achieved with a mean of 7.8 injections over 24 months. Stabilization of visual acuity was also reflected by the scores on the quality of life EQ-5D questionnaire, which did not significantly change over the study period. The more subjective EQ-VAS questionnaire showed an overall improvement. The VFQ-25 questionnaire was also mostly stable over time. After 24 months, 32.2% of the patients gained ≥1 letter and 17.1% gained >15 letters. Patients completing the loading phase were better responders, as demonstrated by increased long-term visual acuity. In addition, ranibizumab was well tolerated and had a safety profile commonly seen in routine clinical practice. This study demonstrates that also in daily practice ranibizumab was effective in preventing vision loss over a period of 24 months. No new safety findings were identified. © 2014 Acta Ophthalmologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

    To evaluate whether yogurt supplemented with a probiotic strain could protect middle-aged and elderly people from acute upper respiratory tract infections (URTI) using a randomized, blank-controlled, parallel-group design. Two hundred and five volunteers aged ≥45 years were randomly divided into two groups. The subjects in the intervention group were orally administered 300 mL/d of yogurt supplemented with a probiotic strain, Lactobacillus paracasei N1115 (N1115), 3.6×10 7 CFU/mL for 12 weeks, while those in the control group retained their normal diet without any probiotic supplementation. The primary outcome was the incidence of URTI, and changes in serum protein, immunoglobulins, and the profiles of the T-lymphocyte subsets (total T-cells [CD3 + ], T-helper cells [CD4 + ], and T-cytotoxic-suppressor cells [CD8 + ]) during the intervention were the secondary outcomes. Compared to the control group, the number of persons diagnosed with an acute URTI and the number of URTI events significantly decreased in the intervention group ( P =0.038, P =0.030, respectively). The risk of URTI in the intervention group was evaluated as 55% of that in the control group (relative risk =0.55, 95% CI: 0.307-0.969). The change in the percentage of CD3 + cells in the intervention group was significantly higher than in the control group ( P =0.038). However, no significant differences were observed in the total protein, albumin, globulin, and prealbumin levels in both groups ( P >0.05). The study suggested that yogurt with selected probiotic strains such as N1115 may reduce the risk of acute upper tract infections in the elderly. The enhancement of the T-cell-mediated natural immune defense might be one of the important underlying mechanisms for probiotics to express their anti-infective effects.

    Despite the availability of efficacious treatments, only half of patients with hypertension achieve adequate blood pressure (BP) control. This paper describes the protocol and baseline subject characteristics of a 2-arm, 18-month randomized clinical trial of titrated disease management (TDM) for patients with pharmaceutically-treated hypertension for whom systolic blood pressure (SBP) is not controlled (≥140mmHg for non-diabetic or ≥130mmHg for diabetic patients). The trial is being conducted among patients of four clinic locations associated with a Veterans Affairs Medical Center. An intervention arm has a TDM strategy in which patients' hypertension control at baseline, 6, and 12 months determines the resource intensity of disease management. Intensity levels include: a low-intensity strategy utilizing a licensed practical nurse to provide bi-monthly, non-tailored behavioral support calls to patients whose SBP comes under control; medium-intensity strategy utilizing a registered nurse to provide monthly tailored behavioral support telephone calls plus home BP monitoring; and high-intensity strategy utilizing a pharmacist to provide monthly tailored behavioral support telephone calls, home BP monitoring, and pharmacist-directed medication management. Control arm patients receive the low-intensity strategy regardless of BP control. The primary outcome is SBP. There are 385 randomized (192 intervention; 193 control) veterans that are predominately older (mean age 63.5 years) men (92.5%). 61.8% are African American, and the mean baseline SBP for all subjects is 143.6mmHg. This trial will determine if a disease management program that is titrated by matching the intensity of resources to patients' BP control leads to superior outcomes compared to a low-intensity management strategy.

    Full Text Available Objective. This clinical trial was designed to investigate whether goshajinkigan reduces the onset of diabetic complications or not. Materials and Methods. A total of 332 type 2 diabetic mellitus patients were registered from 9 clinical centers from March 2000 to August 2007. Patients were randomly assigned to take goshajinkigan extract powder, 2.5 grams for 3 times a day or no kampo therapy, additionally to the regular treatment. The primary endpoints were the onset of macrovascular diseases or progression of nephropathy or retinopathy. Statistical analysis was performed by the intention-to-treat method. Results. After 5 years of observation, 116 patients were submitted to analysis. Among them, no macrovascular events were observed in both groups. Although 43 participants had upstaging of retinopathy or nephropathy in total, there was no significant difference between goshajinkigan group and control group. Deterioration of ankle reflex was suppressed in goshajinkigan group. Also glycated hemoglobin, and fasting plasma glucose were decreased in the goshajinkigan group. Conclusion. Although the power of analysis was too low to demonstrate any effects of goshajinkigan on the progression of macrovascular diseases, retinopathy or nephropathy, goshajinkigan may be beneficial for diabetic neuropathy and glycemic control.

    Non-communicable diseases are expected to kill more people in the 21 st century which are the resultant of deranged lifestyle such as unhealthy dietary habits and wrong behavioral pattern. In Ayurveda, Ahara Vidhi (dietary rules) and Vihara (conducts) are described in detail which can be included under the heading of lifestyle. Agnimandya (indigestion) is considered as the root cause of all diseases like diabetes mellitus, obesity etc., which are few among the top ten lifestyle disorders. The present study is aimed at establishment of relationship between disturbances in lifestyle and Agnimandya and role of lifestyle modification in correcting the state of Agnimandya . The present study was carried out on 33 patients diagnosed with Agnimandya having disturbed lifestyle. Patients were divided into two groups with simple random sampling method. In Group A, lifestyle modification was advised with placebo capsules of wheat flour, while in Group B, patients were treated with 2 g of Shatapushpadya Churna for 2 weeks. Both the groups showed statistically highly significant results on majority of the symptoms of Agnimandya , however, Group A provided better effect than Group B. Lifestyle has definite role in the manifestation and treatment of Agnimandya .

    To evaluate the effects of the lactic acid bacterium Lactobacillus salivarius on caries risk factors. The study was performed in 64 healthy volunteers to evaluate the effects of L. salivarius-containing tablets on caries risk factors. The participants were divided randomly into four groups, and took tablets containing L. salivarius WB21, L. salivarius TI 2711, Ovalgen® DC (antibody against glucosyltransferase from Streptococcus mutans), or xylitol. Levels of mutans streptococci and lactobacilli, amount of salivary flow, salivary pH, and salivary buffering capacity were assessed before and after taking the tablets. Subsequently, a short-term administration trial using L. salivarius WB21-containing tablets was performed in eight healthy volunteers. The participants took L. salivarius WB21-containing tablets (2.0 × 10(9) colony forming units/day) for 2 weeks, and the numbers of mutans streptococci in saliva were counted. The levels of mutans streptococci seemed to decrease in the L. salivarius WB21, TI 2711, and Ovalgen® DC groups compared to the xylitol group, with no significant differences between the groups. Lactobacilli levels significantly increased in the L. salivarius WB21 and TI 2711 groups compared to the other groups. Concerning salivary flow and salivary pH, no significant differences were observed between the groups. The salivary buffering capacity significantly increased in the L. salivarius TI 2711 group (P = 0.003) and Ovalgen® DC group (P = 0.002) compared to the xylitol group. The short-term administration trial showed that the L. salivarius WB21-containing tablets significantly decreased the number of mutans streptococci (P = 0.039). L. salivarius-containing tablets were suggested to increase resistance to caries risk factors. UMIN000013160 (registration date: February 14, 2014).

    Benign prostatic hyperplasia (BPH) is a common and progressive disease affecting elderly males, often associated with lower urinary tract symptoms (LUTS). α1-blockers are the mainstay in symptomatic therapy of BPH. Because of their greater uroselectivity and minimal hemodynamic effects, alfuzosin, tamsulosin, and silodosin are generally preferred. The aim of this study was to compare the efficacy and tolerability of alfuzosin, tamsulosin, and silodosin in patients with BPH and LUTS. Ninety subjects with BPH and LUTS were randomized into three groups of thirty in each, to receive alfuzosin sustained release (SR) 10 mg, tamsulosin 0.4 mg, or silodosin 8 mg for 12 weeks. The primary outcome measure was a change in the International Prostate Symptom Score (IPSS), and the secondary outcome measures were changes in individual subjective symptom scores, quality of life score (QLS), and peak flow rate (Qmax) from baseline. The treatment response was monitored at 2, 4, 8, and 12 weeks. IPSS improved by 88.18%, 72.12%, and 82.23% in alfuzosin SR, tamsulosin and silodosin groups (P 75% in all the three groups (P tamsulosin (P = 0.025 and P tamsulosin (three subjects). Alfuzosin, tamsulosin, and silodosin showed similar efficacy in improvement of LUTS secondary to BPH, with good tolerability, acceptability, and minimum hemodynamic adverse effects. Alfuzosin, tamsulosin, and silodosin are comparable in efficacy in symptomatic management of BPH. The occurrence of QTc prolongation in three subjects with tamsulosin in the present study is an unexpected adverse event as there are no reports of QTc prolongation with tamsulosin in any of the previous studies.

    The artemether-lumefantrine combination requires food intake for the optimal absorption of lumefantrine. In an attempt to enhance the bioavailability of lumefantrine, new solid dispersion formulations (SDF) were developed, and the pharmacokinetics of two SDF variants were assessed in a randomized, open-label, sequential two-part study in healthy volunteers. In part 1, the relative bioavailability of the two SDF variants was compared with that of the conventional formulation after administration of a single dose of 480 mg under fasted conditions in three parallel cohorts. In part 2, the pharmacokinetics of lumefantrine from both SDF variants were evaluated after a single dose of 480 mg under fed conditions and a single dose of 960 mg under fasted conditions. The bioavailability of lumefantrine from SDF variant 1 and variant 2 increased up to ∼48-fold and ∼24-fold, respectively, relative to that of the conventional formulation. Both variants demonstrated a positive food effect and a less than proportional increase in exposure between the 480-mg and 960-mg doses. Most adverse events (AEs) were mild to moderate in severity and not suspected to be related to the study drug. All five drug-related AEs occurred in subjects taking SDF variant 2. No clinically significant treatment-emergent changes in vital signs, electrocardiograms, or laboratory blood assessments were noted. The solid dispersion formulation enhances the lumefantrine bioavailability to a significant extent, and SDF variant 1 is superior to SDF variant 2. Copyright © 2017 Jain et al.

    Tri-Sura-Phon (TSP), a traditional Thai polyherbal formula renowned for its rejuvenating properties, is commonly used as a blood tonic. It comprises Cinnamomum bejolghota , Cinnamomum parthenoxylon , and Aquilaria crassna . The aim of this study is to evaluate the beneficial properties of TSP tea consumption on blood glucose regulation and serum lipid profiles of healthy overweight volunteers. This open-label, randomized controlled trial was conducted in 70 healthy overweight adults. Two groups of 35 subjects took a TSP infusion or a placebo (cornstarch) twice daily for 8 weeks. The blood glucose regulation, serum lipid profiles, BMI, and liver function tests of the subjects were determined at the baseline, 4th week, and endpoint (8th week). Significant decreases in the average fasting levels of total cholesterol ( p = 0.013), triglyceride ( p = 0.001), and low-density lipoprotein (LDL, p = 0.017) were observed in the TSP group at the 8th week compared to those at the baseline. The average HDL level in the TSP group at the beginning of the study was 65.2 mg/dL, and it increased significantly ( p = 0.005) to 72.4 mg/dL after 8 weeks of TSP intake. This study showed that the intake of TSP tea as an antioxidant-rich beverage might be safe and improve lipid profiles in overweight adults.

    Full Text Available Average bioequivalence of two 500 mg levofloxacin formulations available in Brazil, Tavanic(c (Sanofi-Aventis Farmacêutica Ltda, Brazil, reference product and Levaquin(c (Janssen-Cilag Farmacêutica Ltda, Brazil, test product was evaluated by means of a randomized, open-label, 2-way crossover study performed in 26 healthy Brazilian volunteers under fasting conditions. A single dose of 500 mg levofloxacin tablets was orally administered, and blood samples were collected over a period of 48 hours. Levofloxacin plasmatic concentrations were determined using a validated HPLC method. Pharmacokinetic parameters Cmax, Tmax, Kel, T1/2el, AUC0-t and AUC0-inf were calculated using noncompartmental analysis. Bioequivalence was determined by calculating 90% confidence intervals (90% CI for the ratio of Cmax, AUC0-t and AUC0-inf values for test and reference products, using logarithmic transformed data. Tolerability was assessed by monitoring vital signs and laboratory analysis results, by subject interviews and by spontaneous report of adverse events. 90% CIs for Cmax, AUC0-t and AUC0-inf were 92.1% - 108.2%, 90.7% - 98.0%, and 94.8% - 100.0%, respectively. Observed adverse events were nausea and headache. It was concluded that Tavanic(c and Levaquin(c are bioequivalent, since 90% CIs are within the 80% - 125% interval proposed by regulatory agencies.

    To assess the efficacy and safety of teneligliptin as add-on to insulin monotherapy in patients with type 2 diabetes mellitus (T2DM). In a 16-week, double-blind period, 148 Japanese T2DM patients with inadequate glycemic control with insulin and diet/exercise therapies were randomized to placebo or teneligliptin 20 mg. In a subsequent 36-week, open-label period, all patients received teneligliptin once daily. The primary outcome measure was change in HbA1c at the end of the double-blind period. The difference between placebo and teneligliptin in change in HbA1c in the double-blind period (least squares mean ± SE) was -0.80% ± 0.11%; teneligliptin was superior (ANCOVA, P 1). The HbA1c-lowering effect of teneligliptin was maintained throughout the open-label period. The incidence of adverse events was 53.5% with placebo and 44.2% with teneligliptin in the double-blind period, 66.7% in the placebo/teneligliptin group in the open-label period, and 77.9% in the teneligliptin/teneligliptin group over both double-blind/open-label periods. The incidence of hypoglycemic symptoms was 11.1% in the placebo/teneligliptin group in the open-label period and 27.3% in the teneligliptin/teneligliptin group over both double-blind/open-label periods. Teneligliptin was effective and well tolerated in Japanese T2DM patients with inadequate glycemic control. NCT02081599.

    How to generalize from randomized placebo controlled trials of ADHD drug treatment in adults to 'real-world' clinical practice is intriguing. This open-labeled prospective observational study examined the effectiveness of long-term stimulant and non-stimulant medication in adult ADHD including dose, side-effects and comorbidity in a clinical setting. A specialized ADHD outpatient clinic gave previously non-medicated adults (n=250) with ADHD methylphenidate as first-line drug according to current guidelines. Patients who were non-tolerant or experiencing low efficacy were switched to amphetamine or atomoxetine. Primary outcomes were changes of ADHD-symptoms evaluated with the Adult ADHD Self-Report Scale (ASRS) and overall severity by the Global Assessment of Functioning (GAF). Secondary outcomes were measures of mental distress, and response on the Clinical-Global-Impressions-Improvement Scale. Data at baseline and follow-ups were compared in longitudinal mixed model analyses for time on-medication, dosage, comorbidity, and side-effects. As results, 232 patients (93%) completed examination at the 12 month endpoint, and 163 (70%) remained on medication. Compared with the patients who discontinued medication, those still on medication had greater percentage reduction in ASRS-scores (median 39%, versus 13%, Ptreatment with stimulants or atomoxetine was associated with a clinically significant reduction in ADHD symptoms and mental distress, and improvement of measured function. No serious adverse events were observed. Copyright © 2014 Elsevier B.V. and ECNP. All rights reserved.

    The purpose of this article was to present a preliminary model to identify the effects of expectancy of treatment success and the patient-provider encounter (PPE) on outcomes in an open-label randomized trial. Eighty participants with chronic cervicogenic headache (CGH) were randomized to 4 groups: 2 levels of treatment dose (8 or 16) and 2 levels of therapy from a chiropractor (spinal manipulation or light massage). Providers were instructed to have equal enthusiasm for all care. Structural equation modeling with standardized path coefficients (beta) was used in a path analysis to identify the effects of patient expectancy and the PPE on CGH pain. The model included monthly pain from baseline to 12 weeks. Expectancy and PPE were evaluated on Likert scales. The patient-provider encounter was measured as patient perception of chiropractor enthusiasm, confidence, and comfort with care. Baseline patient expectancy was balanced across groups. The PPE measures were balanced across groups and consistent over the 8-week treatment period. Treatment and baseline pain had the strongest effects on pain outcomes (|beta| = .46-.59). Expectations had little effect on pain (abs value(beta) value(beta)= .03-.27) and on subsequent confidence in treatment success (abs value(beta)= .09 and .12). Encouraging equipoise in the PPE and balancing expectancy across treatment groups may protect against some confounding related to the absence of blinding in a randomized controlled trial of pain. In this trial, their effects were found to be small relative to the effects of treatment and baseline values. Copyright 2010 National University of Health Sciences. Published by Mosby, Inc.

    The mammalian target of rapamycin (mTOR) inhibitor everolimus has a well-established pharmacokinetics profile. We conducted a randomized, single-center, open-label, two-sequence, two-period crossover study of healthy volunteers to assess the relative bioavailability of everolimus administered as one 5 mg tablet or five 1 mg tablets. Subjects were randomized 1:1 to receive everolimus dosed as one 5 mg tablet or as five 1 mg tablets on day 1, followed by a washout period on days 8-14 and then the opposite formulation on day 15. Blood sampling for pharmacokinetic evaluation was performed at prespecified time points, with 17 samples taken for each treatment period. Primary variables for evaluation of relative bioavailability were area under the concentration-time curve from time zero to infinity (AUCinf) and maximum blood concentration (Cmax). Safety was assessed by reporting the incidence of adverse events (AEs). Twenty-two participants received everolimus as one 5 mg tablet followed by five 1 mg tablets (n=11) or the opposite sequence (n=11). The Cmax of five 1 mg tablets was 48% higher than that of one 5 mg tablet (geometric mean ratio, 1.48; 90% confidence interval [CI], 1.35-1.62). AUCinf was similar (geometric mean ratio, 1.08; 90% CI, 1.02-1.16), as were the extent of absorption and the distribution and elimination kinetics. AEs, all grade 1 or 2, were observed in 54.5% of subjects. Although the extent of absorption was similar, the Cmax of five 1 mg tablets was higher than that of one 5 mg tablet, suggesting these formulations lead to different peak blood concentrations and are not interchangeable at the dose tested.

    Full Text Available Background: Migraine headaches are the most common acute and recurrent headaches. Current treatment of a migraine headache consists of multiple medications for control and prevention of recurrent attacks. Global emergence of alternative medicine led us to examine the efficacy of cupping therapy plus serkangabin syrup in the treatment of migraine headaches. Materials and Methods: This study was a randomized, controlled, open-label, comparative efficacy trial. We randomly assigned patients with migraine into cupping therapy plus serkangabin group (30 patients and conventional treatment group (30 patients. An investigator assessed the severity of headache, frequency of attacks in a week and duration of attacks per hour in 5 visits (at the end of 2 weeks, 1, 3 and 6 months. Generalized estimating equations approach was used to analyze repeated measures data to compare outcomes in both groups. Results: Average age for cupping therapy group and conventional treatment group were 31.7 (±7.6 and 32.6 (±12.7 years, respectively (P = 0.45. After treatment for 2 weeks; and 1, 3 and 6 months, severity of headache (P = 0.80, frequency of migraine attacks (P = 0.63 and duration of attacks per hours (P = 0.48 were similar in conventional and cupping groups but these symptoms were decreased in each group during the study (P < 0.001. Conclusion: There was no significant difference between cupping plus serkangabin therapy and conventional treatment in the treatment and prophylaxis of migraine. The alternative therapy may be used in cases of drug intolerance, no medication response, and in primary care.

    Hypoglycemia is a major cause of morbidity and mortality among preterm infants and its management remains a challenge in resource limited settings. Use of dextrose infusion by the recommended infusion pumps is not feasible in our environment due to their high costs and yet the current use of mini dextrose boluses with syringes as adapted at Mulago national referral and tertiary teaching hospital has unknown efficacy in prevention of hypoglycemia. We determined the efficacy of dextrose infusions by burettes versus two hourly dextrose boluses in prevention of hypoglycemia among preterms admitted in the first 72 hours at Special Care Unit, Mulago Hospital. One hundred and forty preterms aged 0 to 24 hours of life were randomized to receive 10% IV dextrose either as mini boluses or by infusion using burettes in an open label clinical trial. Blood glucose was measured at 0, two hourly for next 6 hours, 6 hourly for next 12 hours and thereafter 12 hourly until end of 72 hours following admission. Primary end point was incidence of hypoglycemia (random blood sugar (RBS) dextrose infusion was computed using 1-RR. From February 2012 to April 2012, 68 preterms in the bolus arm and 72 in the infusion arm were studied. Hypoglycemia was detected in 34% (48/140). The incidence of hypoglycemia in the bolus arm was 59% (40/68) compared to 11% (8/72) in the infusion arm (RR; 0.19, 95% CI; 0.09-0.37). Efficacy (1-RR) of infusion by burettes versus boluses in prevention of hypoglycemia among preterms was 0.81 (95% CI; 0.63-0.90). Continuous 10% dextrose infusion by burettes reduced the incidence of hypoglycemia by 81% in the first 72 hours of admission compared to two hourly 10% mini dextrose boluses among preterms admitted at Special Care Unit, Mulago Hospital.

    Full Text Available Abstract Background Reducing low-density lipoprotein cholesterol (LDL-C is associated with reduced risk for major coronary events. Despite statin efficacy, a considerable proportion of statin-treated hypercholesterolemic patients fail to reach therapeutic LDL-C targets as defined by guidelines. This study compared the efficacy of ezetimibe added to ongoing statins with doubling the dose of ongoing statin in a population of Taiwanese patients with hypercholesterolemia. Methods This was a randomized, open-label, parallel-group comparison study of ezetimibe 10 mg added to ongoing statin compared with doubling the dose of ongoing statin. Adult Taiwanese hypercholesterolemic patients not at optimal LDL-C levels with previous statin treatment were randomized (N = 83 to ongoing statin + ezetimibe (simvastatin, atorvastatin or pravastatin + ezetimibe at doses of 20/10, 10/10 or 20/10 mg or doubling the dose of ongoing statin (simvastatin 40 mg, atorvastatin 20 mg or pravastatin 40 mg for 8 weeks. Percent change in total cholesterol, LDL-C, high-density lipoprotein cholesterol (HDL-C and triglycerides, and specified safety parameters were assessed at 4 and 8 weeks. Results At 8 weeks, patients treated with statin + ezetimibe experienced significantly greater reductions compared with doubling the statin dose in LDL-C (26.2% vs 17.9%, p = 0.0026 and total cholesterol (20.8% vs 12.2%, p = 0.0003. Percentage of patients achieving treatment goal was greater for statin + ezetimibe (58.6% vs doubling statin (41.2%, but the difference was not statistically significant (p = 0.1675. The safety and tolerability profiles were similar between treatments. Conclusion Ezetimibe added to ongoing statin therapy resulted in significantly greater lipid-lowering compared with doubling the dose of statin in Taiwanese patients with hypercholesterolemia. Studies to assess clinical outcome benefit are ongoing. Trial registration Registered at ClinicalTrials.gov: NCT00652327

    Amygdalus scoparia kernel (ASK) oil is traditionally used for Hyperlipidemia. Compared to olive oil, it has higher proportion of unsaturated to saturated fatty acid besides exhibiting higher index of oxidative stability. The lipid-lowering effects of ASK oil however, has not been investigated yet. This study is the first one to evaluate such effects in patients with dyslipidemia. Serum triglyceride levels significantly decreased in the intervention compared to control group (24.80 ± 51.70 vs 3.13 ± 44.80, p -value = 0.03). Serum total cholesterol, LDL and HDL cholesterol levels did not change significantly ( p = 0.28 and p = 0.68 and p = 0.10 respectively). In a double arm, open-label, randomized controlled trial,101 hyperlipidemic patients were recruited. The designation of hyperlipidemia was upon meeting either of the three criteria: having serum low-density lipoprotein (LDL) cholesterol level 130-190 (mg/dl), serum triglyceride level 150-400 (mg/dl), and serum high-density lipoprotein (HDL) cholesterol level less than 50 (mg/dl) for women and 40 (mg/dl) for men. Patients who have ever been prescribed with an antihyperlipidemic medication were excluded. They were randomly assigned to intervention group, receiving the ASK oil, for 60 days and control group. Serum lipid measurements were repeated at the end of the intervention period. ASK oil supplementation may have a positive effect in reducing serum triglyceride level in patients with dyslipidemia without significant effect on serum cholesterol levels.

    Full Text Available Background: Whether Vitamin D supplementation in prediabetes subjects prevents the development of diabetes is a matter of debate, and the results are inconsistent. This open-label, randomized study in subjects with prediabetes evaluated the effect of 12 months of Vitamin D supplementation on glycemic parameters and progression of prediabetes to diabetes in an ethnically homogeneous Kashmiri population. Materials and Methods: A total of 147 subjects were diagnosed as prediabetes out of which 137 subjects were randomized to receive in addition to standard lifestyle measures, either Vitamin D 60,000 IU weekly for 4 weeks and then 60,000 IU monthly (n = 69 or no Vitamin D (n = 68. Fasting plasma glucose (FPG, 2-h plasma glucose and A1C levels were estimated at 0, 6 and 12 months. Changes in FPG, 2-h plasma glucose, A1C level and the proportion of subjects developing diabetes were assessed among 129 subjects. Results: At 12 months, A1C levels were significantly lesser (5.7% ± 0.4% in the Vitamin D supplemented group when compared with non-Vitamin D supplemented (6.0% ± 0.3%. Similarly, FPG (97 ± 7 and 2-h plasma glucose (132 ± 16 were significantly less in Vitamin D supplemented group as compared with non-Vitamin D supplemented group (FPG = 116 ± 6 and 2-h plasma glucose = 157 ± 25 at 12 months. Nine out of 65 in non-Vitamin D supplemented and seven out of 64 in the Vitamin D supplemented group developed diabetes. Conclusions: Vitamin D supplementation in prediabetes subjects significantly lowered FPG, 2-h plasma glucose and A1C levels.

    Fibromyalgia (FM) is a common pain condition characterized by widespread musculoskeletal pain and tenderness. Pregabalin is an approved treatment for adults in the United States, but there are no approved treatments for adolescents with FM. This was a 15-week, randomized, double-blind, placebo-controlled study and 6-month open-label safety trial of flexible-dose pregabalin (75-450 mg/day) for the treatment of adolescents (12-17 years) with FM. Primary outcome was change in mean pain score at endpoint (scored from 0-10, with 24-h recall). Secondary outcomes included global assessments and measures of pain, sleep, and FM impact. A total of 107 subjects were randomized to treatment (54 pregabalin, 53 placebo) and 80 completed the study (44 pregabalin, 36 placebo). Improvement in mean pain score at endpoint with pregabalin versus placebo was not statistically significant, treatment difference (95 % CI), -0.66 (-1.51, 0.18), P = 0.121. There were significant improvements with pregabalin versus placebo in secondary outcomes of change in pain score by week (P recall), treatment difference (95 % CI), -0.87 (-1.68, -0.05), P = 0.037; and patient global impression of change, 53.1 % versus 29.5 % very much or much improved (P = 0.013). Trends toward improvement with pregabalin in other secondary outcomes measuring pain, sleep, and FM impact were not significant. Safety was consistent with the known profile of pregabalin in adults with FM. Pregabalin did not significantly improve the mean pain score in adolescents with FM. There were significant improvements in secondary outcomes measuring pain and impression of change. NCT01020474 ; NCT01020526 .

    The association between the dialysate calcium level and coronary artery calcification (CAC) has not yet been evaluated in hemodialysis patients. The objective of this study was to determine whether lowering the dialysate calcium levels would decrease the progression of coronary artery calcification (CAC) compared to using standard calcium dialysate. We conducted an open-label randomized trial with parallel groups. The patients were randomly assigned to either 12-month treatment with low calcium dialysate (LCD; 1.25mmol/L, n=36) or standard calcium dialysate (SCD; 1.5mmol/L, n=40). The primary outcome was the change in the CAC scores assessed by 64-slice multidetector computed tomography after 12months. During the treatment period, CAC scores increased in both groups, especially significant in LCD group (402.5±776.8, 580.5±1011.9, P=0.004). When we defined progressors as patients at second and third tertiles of CAC changes, progressor group had a higher proportion of LCD-treated patients than SCD-treated patients (P=0.0229). In multivariate analysis, LCD treatment is a significant risk factor for increase in CAC scores (odds ratio=5.720, 95% CI: 1.219-26.843, P=0.027). Use of LCD may accelerate the progression of CAC in patients with chronic hemodialysis over a 12-month period.

    Due to the low uptake, adherence, and completion of vaccination among drug users, and their compromised immune responses to hepatitis B vaccination, the current practice of hepatitis B vaccination may not provide optimal protection. The aim of this study was to evaluate the immunogenicity and safety of 60 µg and 20 µg hepatitis B vaccines among drug users. A randomized, open-labeled, blank-controlled trial was conducted among drug users at 2 drug rehabilitation centers in China. The eligible participants were drug users who were serologically negative for the hepatitis B surface antigen (HBsAg) and the hepatitis B surface antibody (anti-HBs). Participants were randomized in a ratio of 1:1:1 to receive 20 µg (IM20 group) or 60 µg (IM60 group) of hepatitis B vaccine or blank control at months 0, 1, and 6, and followed at months 6, 7, and 12. Seroconversion rates of 94.7% and 92.6% were observed in IM20 and IM60 groups at month 7, and correspondingly decreased to 89.5% and 91.7% respectively at month 12. The IM60 group showed significantly higher geometric mean concentrations (GMCs) of anti-HBs (2022.5 and 676.7 mIU mL-1) than the IM20 group did (909.6 and 470.5 mIU mL-1) at months 7 and 12 (P B vaccines showed good immunogenicity among the drug users.

    Full Text Available Background & objectives: Improving quality of life (QOL of healthy people living with HIV (PLHIV is critical needing home-based, long-term strategy. Sudarshan Kriya yoga (SKY intervention is acknowledged for its positive impact on health. It is hypothesised that SKY would improve PLHIV′s QOL, justifying an evaluation. Methods: In this open label randomized controlled pilot trial, 61 adult PLHIV with CD4 count more than 400 cells/µl and Karnofsky scale score above 70 were enrolled. Those with cardiac disease, jaundice, tuberculosis, or on antiretroviral therapy/yoga intervention were excluded. All were given standard care, randomized to SKY intervention (31: I-SKY and only standard of care in control (30: O-SOC arms. The I-SKY participants were trained for six days to prepare for daily practice of SKY at home for 30 min. A validated 31-item WHOQOL-HIVBREF questionnaire was used to document effect in both arms from baseline to three visits at 4 wk interval. Results: Baseline QOL scores, hypertension and CD4 count were similar in both arms. An overall 6 per cent improvement of QOL scores was observed in I-SKY group as compared to O-SOC group, after controlling for baseline variables like age, gender, education and occupation ( p0 =0.016; 12 per cent for physical ( p0 =0.004, 11 per cent psychological ( p0 =0.023 and 9 per cent level of independence ( p0 =0.001 domains. Improvement in I-SKY observed at post-training and in the SKY adherence group showed increase in these two domains. Conclusions: A significant improvement in QOL scores was observed for the three health related QOL domains in SKY intervention arm. This low cost strategy improved physical and psychological state of PLHIV calling for upscaling with effective monitoring for sustainability of quality of life.

    The use of marginal or extended criteria donor livers is increasing. These organs carry a greater risk of initial dysfunction and early failure, as well as inferior long-term outcomes. As such, many are rejected due to a perceived risk of use and use varies widely between centres. Ex situ normothermic machine perfusion of the liver (NMP-L) may enable the safe transplantation of organs that meet defined objective criteria denoting their high-risk status and are currently being declined for use by all the UK transplant centres. Viability testing and transplantation of marginal livers is an open-label, non-randomised, prospective, single-arm trial designed to determine whether currently unused donor livers can be salvaged and safely transplanted with equivalent outcomes in terms of patient survival. The procured rejected livers must meet predefined criteria that objectively denote their marginal condition. The liver is subjected to NMP-L following a period of static cold storage. Organs metabolising lactate to ≤2.5 mmol/L within 4 hours of the perfusion commencing in combination with two or more of the following parameters-bile production, metabolism of glucose, a hepatic arterial flow rate ≥150 mL/min and a portal venous flow rate ≥500 mL/min, a pH ≥7.30 and/or maintain a homogeneous perfusion-will be considered viable and transplanted into a suitable consented recipient. The coprimary outcome measures are the success rate of NMP-L to produce a transplantable organ and 90-day patient post-transplant survival. The protocol was approved by the National Research Ethics Service (London-Dulwich Research Ethics Committee, 16/LO/1056), the Medicines and Healthcare Products Regulatory Agency and is endorsed by the National Health Service Blood and Transplant Research, Innovation and Novel Technologies Advisory Group. The findings of this trial will be disseminated through national and international presentations and peer-reviewed publications. NCT02740608

    The potential anti-cancer effects of mammalian target of rapamycin (mTOR) inhibitors are being intensively studied. To date, however, few randomised clinical trials (RCT) have been performed to demonstrate anti-neoplastic effects in the pure oncology setting, and at present, no oncology endpoint-directed RCT has been reported in the high-malignancy risk population of immunosuppressed transplant recipients. Interestingly, since mTOR inhibitors have both immunosuppressive and anti-cancer effects, they have the potential to simultaneously protect against immunologic graft loss and tumour development. Therefore, we designed a prospective RCT to determine if the mTOR inhibitor sirolimus can improve hepatocellular carcinoma (HCC)-free patient survival in liver transplant (LT) recipients with a pre-transplant diagnosis of HCC. The study is an open-labelled, randomised, RCT comparing sirolimus-containing versus mTOR-inhibitor-free immunosuppression in patients undergoing LT for HCC. Patients with a histologically confirmed HCC diagnosis are randomised into 2 groups within 4-6 weeks after LT; one arm is maintained on a centre-specific mTOR-inhibitor-free immunosuppressive protocol and the second arm is maintained on a centre-specific mTOR-inhibitor-free immunosuppressive protocol for the first 4-6 weeks, at which time sirolimus is initiated. A 2 1/2 -year recruitment phase is planned with a 5-year follow-up, testing HCC-free survival as the primary endpoint. Our hypothesis is that sirolimus use in the second arm of the study will improve HCC-free survival. The study is a non-commercial investigator-initiated trial (IIT) sponsored by the University Hospital Regensburg and is endorsed by the European Liver and Intestine Transplant Association; 13 countries within Europe, Canada and Australia are participating.

    We conducted a study to compare how well the head impulse test (HIT), without and with eye-movement recordings, would predict videonystagmographic (VNG) caloric test lateralization when performed by a resident and an experienced otoneurologist. This prospective, open-label, blinded study was conducted in an ambulatory tertiary care referral center. Our study population was made up of 60 patients-29 men and 31 women, aged 20 to 82 years (mean: 56.4 ± 11.4)-with peripheral vestibulopathy who underwent HIT and VNG caloric testing. The HIT was conducted in two protocols: HIT0 and HIT1. The HIT0 was performed with passive brisk movements of the patient's head from the 0° null position to 20° sideways, and the HIT1 was performed toward the center while the null position was a 20° head rotation to the right and to the left. Each protocol was carried out without video eye-movement recordings (HIT0 and HIT1) and with such recordings (rHIT0 and rHIT1). The primary outcome measures were (1) a comparison of the HIT's sensitivity and specificity when performed by the resident and by the experienced otoneurologist and (2) the ability of video-recorded HIT to predict VNG caloric test lateralization. The sensitivity and specificity obtained by the resident were 41 and 81%, respectively, for HIT0 and 41 and 90% for HIT1. The sensitivity and specificity obtained by the experienced otoneurologist were 18 and 89% for HIT0 and 32 and 85% for HIT1. Analysis of the recorded eye-movement clips of the HIT0 and HIT1 obtained by a second experienced otoneurologist found a sensitivity and specificity of 32 and 63% for rHIT0 and 33 and 82% for rHIT1. We conclude that the HIT yields high false-negative rates in predicting significant caloric lateralization. Analysis of the eye-movement recordings was no better than normal testing alone for detecting saccades. The experience of the examining physician had no impact on test performance characteristics.

    Omega-3-carboxylic acids (OM3-CA) contain omega-3 free fatty acids, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), as carboxylic acids. Food intake is known to affect the bioavailability of ethyl ester fatty acid formulations. We conducted a phase I study to investigate the effects of the timing of OM3-CA administration relative to food intake on the pharmacokinetics of EPA and DHA. In this randomized, open-label, three-period crossover study, Japanese healthy male subjects were administered 4×1 g OM3-CA capsules with continued fasting, before a meal, or after a meal. All subjects fasted for ≥10 h prior to drug/meal administration. The primary objective was to examine the effect of meal timing on the pharmacokinetics of EPA and DHA after OM3-CA administration. The secondary objectives were to examine the safety and tolerability of OM3-CA. A total of 42 Japanese subjects was enrolled in the study. The baseline-adjusted maximum concentration and area under the concentration-time curve from 0 to 72 h for EPA, DHA, and EPA +DHA were lower in the fasting and before meal conditions than in the after meal condition. The maximum total EPA, total DHA, and total EPA+DHA concentrations were reached later when administered in fasting conditions than in fed conditions, indicating slower absorption in fasting conditions. Diarrhea was reported by five, six, and no subjects in the fasting, before meal, and after meal conditions, respectively. The timing of OM3-CA administration relative to food intake influences the systemic bioavailability of EPA and DHA in healthy Japanese male subjects. NCT02372344.

    This randomized, controlled, open-label study conducted in Kangbuk Samsung Hospital evaluated the effectiveness, reproducibility, and durability of tailored mobile coaching (TMC) on diabetes management. The participants included 148 Korean adult policyholders with type 2 diabetes divided into the Intervention-Maintenance (I-M) group (n = 74) and Control-Intervention (C-I) group (n = 74). Intervention was the addition of TMC to typical diabetes care. In the 6-month phase 1, the I-M group received TMC, and the C-I group received their usual diabetes care. During the second 6-month phase 2, the C-I group received TMC, and the I-M group received only regular information messages. After the 6-month phase 1, a significant decrease (0.6%) in HbA1c levels compared with baseline values was observed in only the I-M group (from 8.1 ± 1.4% to 7.5 ± 1.1%, P < 0.001 based on a paired t-test). At the end of phase 2, HbA1c levels in the C-I group decreased by 0.6% compared with the value at 6 months (from 7.9 ± 1.5 to 7.3 ± 1.0, P < 0.001 based on a paired t-test). In the I-M group, no changes were observed. Both groups showed significant improvements in frequency of blood-glucose testing and exercise. In conclusion, addition of TMC to conventional treatment for diabetes improved glycemic control, and this effect was maintained without individualized message feedback.

    The number of injections in the dose escalation of subcutaneous immunotherapy (SCIT) is small for some currently used hypoallergenic allergoids, but can still be inconvenient to patients and can impair compliance. The aim of this trial was to compare safety and tolerability of an accelerated to the conventional dose escalation scheme of a grass pollen allergoid. In an open label phase II trial, 122 patients were 1:1 randomized for SCIT using a grass pollen allergoid with an accelerated dose escalation comprising only 4 weekly injections (Group I) or a conventional dose escalation including 7 weekly injections (Group II). Safety determination included the occurrence of local and systemic adverse events. Tolerability was assessed by patients and physicians. Treatment-related adverse events were observed in 22 (36.1 %) patients in Group I and 15 (24.6 %) in Group II. Local reactions were reported by 18 patients in Group I and 11 in Group II. Five Grade 1 systemic reactions (WAO classification) were observed in Group I and 2 in Group II. Grade 2 reactions occurred 3 times in Group I and 2 times in Group II. Tolerability was rated as "good" or "very good" by 53 (86.9 %) patients in Group I and 59 (100 %) in Group II by investigators. Forty-eight patients in Group I (80.0 %) and 54 in Group II (91.5 %) rated tolerability as "good" or "very good". The dose escalation of a grass pollen allergoid can be accelerated with safety and tolerability profiles comparable to the conventional dose escalation.

    Full Text Available The co-primary objectives of this study were to determine the human pharmacokinetics (PK of oral NR and the effect of NR on whole blood nicotinamide adenine dinucleotide (NAD+ levels.Though mitochondrial dysfunction plays a critical role in the development and progression of heart failure, no mitochondria-targeted therapies have been translated into clinical practice. Recent murine studies have reported associations between imbalances in the NADH/NAD+ ratio with mitochondrial dysfunction in multiple tissues, including myocardium. Moreover, an NAD+ precursor, nicotinamide mononucleotide, improved cardiac function, while another NAD+ precursor, nicotinamide riboside (NR, improved mitochondrial function in muscle, liver and brown adipose. Thus, PK studies of NR in humans is critical for future clinical trials.In this non-randomized, open-label PK study of 8 healthy volunteers, 250 mg NR was orally administered on Days 1 and 2, then uptitrated to peak dose of 1000 mg twice daily on Days 7 and 8. On the morning of Day 9, subjects completed a 24-hour PK study after receiving 1000 mg NR at t = 0. Whole-blood levels of NR, clinical blood chemistry, and NAD+ levels were analyzed.Oral NR was well tolerated with no adverse events. Significant increases comparing baseline to mean concentrations at steady state (Cave,ss were observed for both NR (p = 0.03 and NAD+ (p = 0.001; the latter increased by 100%. Absolute changes from baseline to Day 9 in NR and NAD+ levels correlated highly (R2 = 0.72, p = 0.008.Because NR increases circulating NAD+ in humans, NR may have potential as a therapy in patients with mitochondrial dysfunction due to genetic and/or acquired diseases.

    To evaluate the bioequivalence of a new formulation of atomoxetine hydrochloride (CAS 82248-59-7) capsules (test) and an available branded capsules (reference) after administration of a single 40 mg dose, randomized, open-label, 2-period crossover study was conducted in 22 healthy male Chinese subjects with a 1-week wash-out period. This study was designed for/the Honglin Pharmaceutical Co. Ltd and contracted to be done by the Beijing Anding Hospital in order to satisfy Chinese regulatory requirements to allow marketing of this generic product and performed according to the criteria of SFDA. Blood samples were collected before and 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 9, 12, 16 and 24 h after drug administration. Plasma concentrations were determined by high-performance liquid chromatography (HPLC) with UV detection. A non-compartmental method was used to calculate the pharmacokinetic parameters and evaluate bioequivalence of the 2 formulations. The 90% confidence interval (CI) of the ratios (test/reference) of atomoxetine for AUC0-24, AUC0-∞ and Cmax were 100.9% (93.6-108.8%), 103.1% (95.1-111.7%) and 105.2% (92.8-119.4%), respectively, which fell within the interval of 80-125% and 75-133%. No clinically significant changes or abnormalities were noted in laboratory data and vital signs. From these results it can be concluded that the test formulation of atomoxetine capsules met the regulatory criterion for bioequivalence to the reference formulation. © Georg Thieme Verlag KG Stuttgart · New York.

    Treatment of complicated skin and skin structure infection (cSSSI) places a tremendous burden on the health care system. Understanding relative resource utilization associated with different antimicrobials is important for decision making by patients, health care providers, and payers. The authors conducted an open-label, pragmatic, randomized (1:1) clinical study (N = 250) to compare the effectiveness of daptomycin with that of vancomycin for treatment of patients hospitalized with cSSSI caused by suspected or documented methicillin-resistant Staphylococcus aureus infection. The primary study end point was infection-related length of stay (IRLOS). Secondary end points included health care resource utilization, cost, clinical response, and patient-reported outcomes. Patient assessments were performed daily until the end of antibiotic therapy or until hospital discharge, and at 14 days and 30 days after discharge. No difference was found for IRLOS, total LOS, and total inpatient cost between cohorts. Hospital LOS contributed 85.9% to the total hospitalization cost, compared with 6.4% for drug costs. Daptomycin showed a nonsignificant trend toward a higher clinical success rate, compared with vancomycin, at treatment days 2 and 3. In the multivariate analyses, vancomycin was associated with a lower likelihood of day 2 clinical success (odds ratio [OR] = 0.498, 95% confidence interval [CI], 0.249-0.997; P < 0.05). This study did not provide conclusive evidence of the superiority of one treatment over the other in terms of clinical, economic, or patient outcomes. The data suggest that physician and patient preference, rather than drug acquisition cost, should be the primary driver of initial antibiotic selection for hospitalized patients with cSSSI.

    Primary open angle glaucoma is an insidious and chronic vision-threatening eye ailment due to neuro-retino-optic nerve degeneration, which may be due to the raised intraocular pressure (IOP) or due to independent factors. Management of glaucoma is mainly concentrated on lowering IOP that requires lifetime topical medication, different ocular medicaments for lowering of IOP, and surgical interventions, but it has its own limitations to control the progression of glaucomatous optic neuropathy (GON), and this is the reason behind the use of alternative neuroprotective adjuvants. To evaluate the neuroprotective effect of Ayurvedic line of management of progressive GON. Ingredients of trial drug Vara Fort powder ( Chakshushya Rasayana ) were procured from the Institute Pharmacy, except Swarnamakshika Bhasma , which was purchased from Dhootapapeshwar Pharmaceuticals. The patients fulfilling inclusion criteria, attending outpatient and inpatient departments, irrespective of their sex, race, religion, occupation, etc., were selected and divided into two groups with open-labeled randomization. In Group A, in addition to betaxolol (0.1%) or timolol (0.5%) (non-iobrim), Chakshushya Rasayana 6 g/day orally with Triphala Ghrita and honey along with Koshtha-Shuddhi (body-microchannel clearing treatment) protocol was tried. Nasya (oleation through nasal route) with Jeevantyadi Taila and Tarpana (eye satiation) with Go-Ghrita were also performed. In Group B (control), brimonidine (iobrim) 0.2% eye drop was used for 3 months. Significant improvement was observed in subjective parameters in Group A such as blurred vision, frequent change of presbyopic glasses, and delayed dark adaptation. Chakshushya Rasayana , if administered in a systematic approach along with a modern topical betaxolol or timolol eye drops, has a definite role in improving the lost retinal sensitivity as much as up to 12 dB in 3 months duration.

    Full Text Available Background: Finasteride and dutasteride are inhibitors of the enzyme 5-alpha-reductase which inhibits the conversion of testosterone to dihydrotestosterone. Dutasteride inhibits both type I and type II 5-alpha-reductase while finasteride inhibits only the type II enzyme. As both isoenzymes are present in hair follicles, it is likely that dutasteride is more effective than finasteride. Aims: To compare the efficacy, safety and tolerability of dutasteride and finasteride in men with androgenetic alopecia. Methods: Men with androgenetic alopecia between 18 and 40 years of age were randomized to receive 0.5 mg dutasteride or 1 mg finasteride daily for 24 weeks. The primary efficacy variables were hair counts (thick and thin in the target area from modified phototrichograms and global photography evaluation by blinded and non-blinded investigators. The secondary efficacy variable was subjective assessment using a preset questionnaire. Patients were assessed monthly for side effects. Results: Ninety men with androgenetic alopecia were recruited. The increase in total hair count per cm[2] representing new growth was significantly higher in dutasteride group (baseline- 223 hair; at 24 weeks- 246 hair compared to finasteride group (baseline- 227 hair; at 24 weeks- 231 hair. The decrease in thin hair count per cm[2] suggestive of reversal of miniaturization was significantly higher in dutasteride group (baseline- 65 hair; at 24 weeks- 57 hair compared to finasteride group (baseline- 67 hair; at 24 weeks- 66 hair. Both the groups showed a similar side effect profile with sexual dysfunction being the most common and reversible side effect. Limitations: Limitations include the short duration of the study (6 months, the small sample size and the fact that it was an open-label study. Conclusions: Dutasteride was shown to be more efficacious than finasteride and the side-effect profiles were comparable.

    Full Text Available Herbal sedatives serve an alternative to antipsychotics and hypnotics aimed to alleviate symptoms of anxious disorders and insomnia. Valeriana officinalis L., Mentha piperita L. and Melissa officinalis are most widely used in neurology as sedatives of herbal origin. We present the results of a randomized open-label trial on efficiency and safety of Persen® and Persen® Night containing extracts of the above mentioned plants in patients with short-term insomnia. The study consisted of 60 subjects of 18–65 y.o. (mean 42.4 ± 6.9 y.o. with short-term insomnia due to adjustment disorder or mixed anxiety-depressive disorders: 30 of them got Persen® 2 tablets a day and 30 – Persen® Night, 1 capsule 30–60 min before sleep during 4 weeks. The majority (76.5 % of patients referred the onset of insomnia with psychosocial traumatic stressor. Persen® Night’s main action was found on superficial sleep, number of night awakenings, sleep onset rate. At the end of the therapy with this substance 39.7 % of patients fell asleep in 10–15 min, and 92.2 % – in 30 min, accordingly, while for Persen® at 17.4 and 80.3 % accordingly (р < 0.05. In the meantime Persen® decreased the bad sleep perception at awakening and day somnolence, mostly attributed to the mood improvement and decrease of anxiety. Levels of efficacy and safety for both substances were significant, allowing to regard them as potential phytotherapeutic agent in the treatment of insomnia and mixed anxiety-depressive disorders.

    Hypercholesterolemia is a major risk factor for cardiovascular disorders and requires specific intervention through an adequate lifestyle (diet and physical exercise) and, if necessary, an appropriate drug treatment. Lipid-lowering drugs, although generally efficacious, may sometimes cause adverse events. A growing attention has been devoted to the correction of dyslipidemias through the use of dietary supplements. The aim of this study was to assess the lipid-lowering activity and safety of a dietary supplement containing monacolin K, L-arginine, coenzyme Q10 and ascorbic acid, named Argicolina (A), compared to a commercially available product containing monacolin K and coenzyme Q10, Normolip 5 (N). This was a single center, controlled, randomized, open-label, cross-over clinical study enrolling 20 Caucasian outpatients aged 18-75 years with serum LDL-C between 130 and 180 mg/dL. Patients assumed two different dietary supplements (A and N) both containing monacolin K 10 mg for 8 weeks each, separated by a 4-week wash-out period. Evaluated parameters were: Total cholesterol (Tot-C), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), triglycerides (TG), fasting blood glucose, aspartate aminotransferase, alanine aminotransferase, creatinekinase, gamma-glutamyl-transpeptidase, brachial arterial pressure and heart rate, measured at the start and at the end of each treatment period. Safety was monitored through the study. LDL-C decreased by 23.3% during treatment with N (p ascorbic acid also produces a significant reduction of triglycerides without significant effects on HDL.

Low-dose estrogen/progestin combined oral contraceptives have been shown to reduce the severity of dysmenorrhea symptoms, and a 28-day cyclic regimen of ethinylestradiol/drospirenone (28d regimen is approved for this indication in Japan. Aim: The aim of this study was to assess the safety and efficacy of a flexible extended regimen of ethinylestradiol/drospirenone (flexible regimen in Japanese women with dysmenorrhea. Methods: This multicenter, open-label study was performed in Japanese women with dysmenorrhea who, after a baseline observational phase, were randomized to receive ethinylestradiol 20 µg/drospirenone 3 mg in a flexible regimen (one tablet each day for 24–120 days followed by a 4-day tablet-free interval or in the standard 28d regimen (one tablet each day for 24 days, followed by 4 days of placebo tablets for six cycles. The primary endpoint was the number of days with dysmenorrhea of at least mild intensity over a 140-day evaluation period. Dysmenorrhea scores, bleeding patterns, and other pain-related parameters were also assessed. Results: A total of 216 women (mean age 29.7 years were randomized to the flexible regimen (n=108 or 28d regimen (n=108 and 212 were included in the full analysis sets (flexible regimen, n=105; 28d regimen, n=107.

    The present study was designed to evaluate effect of heart failure reversal therapy (HFRT) using herbal procedure (panchakarma) and allied therapies, as add-on to standard CHF treatment (SCT) in chronic heart failure (CHF) patients. This open-label, randomized study conducted in CHF patients (aged: 25-65 years, ejection fraction: 30-65%), had 3-phases: 1-week screening, 6-week treatment (randomized [1:1] to HFRT+SCT or SCT-alone) and follow-up (12-week). Twice weekly HFRT (60-75min) consisting of snehana (external oleation), swedana (passive heat therapy), hrudaydhara (concoction dripping treatment) and basti (enema) was administered. Primary endpoints included evaluation of change in metabolic equivalents of task (MET) and peak oxygen uptake (VO 2peak ) from baseline, at end of 6-week treatment and follow-up at week-18 (non-parametric rank ANCOVA analysis). Safety and quality of life (QoL) was assessed. Seventy CHF patients (n=35, each treatment-arm; mean [SD] age: 53.0 [8.6], 80% men) were enrolled in the study. All patients completed treatment phase. Add-on HFRT caused a significant increase in METs (least square mean difference [LSMD], 6-week: 1.536, p=0.0002; 18-week: -1.254, p=0.0089) and VO 2peak (LSMD, 6-week: -5.52, p=0.0002; 18-week: -4.517, p=0.0089) as compared with SCT-alone. Results were suggestive of improved functional capacity in patients with HFRT (QoL; Mean [SD] HFRT+SCT vs. SCT-alone; 6-week: -0.44 [0.34] vs. -0.06 [0.25], p<0.0001 and 18-week: -0.53 [0.35] vs. -0.29 [0.26], p=0.0013). Seven treatment-emergent adverse events (mild severity) were reported in HFRT-arm. Findings of this study highlight therapeutic efficacy of add-on HFRT vs. SCT-alone in CHF patients. The non-invasive HFRT showed no safety concerns. Copyright © 2016. Published by Elsevier B.V.

    To compare the changes induced by oral versus transdermal estrogen therapy on the total and free serum concentrations of testosterone (T), thyroxine (T4), and cortisol (C) and the concentrations of their serum binding globulins sex hormone-binding globulin, thyroxine-binding globulin, and cortisol-binding globulin in naturally menopausal women. Randomized, open-label, crossover. Interventions included a 6-week withdrawal from previous hormone therapy (baseline), followed in randomized order by 12 weeks of oral conjugated equine estrogens (CEE) (0.625 mg/d) and 12 weeks of transdermal estradiol (TD E2) (0.05 mg/d), with oral micronized progesterone (100 mg/d) given continuously during both transdermal estrogen therapy regimens. Twenty-seven women were enrolled in the study, and 25 completed both treatment periods. The mean(SD) percentage changes from baseline of sex hormone-binding globulin, total T, and free T with oral CEE were +132.1% (74.5%), +16.4% (43.8%), and -32.7% (25.9%), respectively, versus +12.0% (25.1%), +1.2% (43.7%), and +1.0% (45.0%) with TD E2. The mean (SD) percentage changes of thyroxine-binding globulin, total T4, and free T4 with oral CEE were +39.9% (20.1%), +28.4% (29.2%), and -10.4% (22.3%), respectively, versus +0.4% (11.1%), -0.7% (16.5%), and +0.2% (26.6%) with TD E2. The mean (SD) percentage changes of cortisol-binding globulin, total C, and free C with oral CEE were +18.0% (19.5%), +29.2% (46.3%), and +50.4% (126.5%), respectively, versus -2.2% (11.3%), -6.7% (30.8%), and +1.8% (77.1%) with TD E2. Concentrations of all hormones and binding globulins were significantly different (P < or = 0.003) during administration of oral versus transdermal estrogen therapy, except for free T4 and free C. Compared with oral CEE, TD E2 exerts minimal effects on the total and free concentrations of T, T4, and C and their binding proteins.

    In Korea, increasing attention has recently been given to the use of phytotherapeutic agents to alleviate the symptoms of BPH. Serenoa repens has been shown to have an equivalent efficacy to Finasteride or Tamsulosin in the treatment of BPH in previous studies. The present study was designed to compare the efficacy and safety of Serenoa repens plus tamsulosin with tamsulosin only over 12 months in men with LUTS secondary to BPH. One hundred forty men with symptomatic BPH (IPSS≥10) were recruited in our hospital for a 12-month, open-label, randomized trial. Patients were randomly assigned to either tamsulosin 0.2 mg/day plus Serenoa repens 320 mg/day (n=60) or tamsulosin 0.2 mg/day only (n=60). Prostate volume and PSA were measured at baseline and at end-point, whereas total IPSS, and its storage and voiding subscores, LUTS-related QoL, Qmax, and PVR were evaluated at baseline and later every 6 months. Total 103 patients were finally available: 50 in the TAM+SR group and 53 in the TAM group. At 12 months, total IPSS decreased by 5.8 with TAM+SR and 5.5 with TAM (p=0.693); the storage symptoms improved significantly more with TAM+SR (-1.7 vs. -0.8 with TAM, p=0.024). This benefit with regard to storage symptom in the TAM+SR group lasts at 12 months (-1.9 vs. -0.9, p=0.024). The changes of voiding subscore, LUTS-related QoL, Qmax, PVR, PSA, and prostate volume showed no significant differences between the TAM+SR and TAM groups. During the treatment period, 8 patients (16.9%) with TAM and 10 (20%) with TAM+SR had drug-related adverse reactions, which included ejaculatory disorders, postural hypotension, dizziness, headache, gastro-intestinal disorders, rhinitis, fatigue and asthenia. The combination treatment of Serenoa repens and tamsulosin was shown to be more effective than tamsulosin monotherapy in reducing storage symptoms in BPH patients after 6 months and up to 12 months of treatment. © 2015 S.

    ♦ Catheter-related infection, namely exit-site infection (ESI) and peritonitis, is a major infectious complication and remains a main cause of technique failure for patients receiving peritoneal dialysis (PD). Topical application of antibiotic cream might reduce catheter-related infection but emergence of resistant or opportunistic organisms could be a concern. Optimal topical agents and regimens remain to be determined. We did a study to examine the effect of an alternating topical antibiotic regimen in preventing catheter-related infection. ♦ We performed a single-center, randomized, open-label study to compare daily topical application of gentamicin cream with a gentamicin/mupirocin alternate regimen to the exit site. Patients randomized to alternating regimen were asked to have daily application of gentamicin cream in odd months and mupirocin cream in even months. Primary outcomes were ESI and peritonitis. Secondary outcomes were catheter removal or death caused by catheter-related infection. A total of 146 patients (71, gentamicin group; 75, alternating regimen group) were enrolled with a total follow-up duration of 174 and 181 patient-years for gentamicin and alternating groups, respectively. All patients were followed up until catheter removal, death, transfer to another unit, transplantation or the end of the study on March 31, 2014. There were no significant differences in the age, sex, dialysis vintage, and rate of diabetes, helper-assisted dialysis and methicillin-resistant Staphylococcus aureus (MRSA) carriage state. ♦ No difference was seen in the time to first ESI or peritonitis. However, the time to first gram-negative peritonitis seemed longer for the gentamicin group (p = 0.055). The 2 groups showed a similar rate of ESI (0.17/yr vs 0.19/yr, p = 0.93) but P. aeruginosa ESI was less common in the gentamicin group (0.06/yr vs 0.11/yr, p Peritonitis rate was significantly lower in the gentamicin group (0.22/yr vs 0.32/yr, p peritonitis (0.08/yr

    High-frequency deep brain stimulation (DBS) with a single electrical source is effective for motor symptom relief in patients with Parkinson's disease. We postulated that a multiple-source, constant-current device that permits well defined distribution of current would lead to motor improvement in patients with Parkinson's disease. We did a prospective, multicentre, non-randomised, open-label intervention study of an implantable DBS device (the VANTAGE study) at six specialist DBS centres at universities in six European countries. Patients were judged eligible if they were aged 21-75 years, had been diagnosed with bilateral idiopathic Parkinson's disease with motor symptoms for more than 5 years, had a Hoehn and Yahr score of 2 or greater, and had a Unified Parkinson's disease rating scale part III (UPDRS III) score in the medication-off state of more than 30, which improved by 33% or more after a levodopa challenge. Participants underwent bilateral implantation in the subthalamic nucleus of a multiple-source, constant-current, eight-contact, rechargeable DBS system, and were assessed 12, 26, and 52 weeks after implantation. The primary endpoint was the mean change in UPDRS III scores (assessed by site investigators who were aware of the treatment assignment) from baseline (medication-off state) to 26 weeks after first lead implantation (stimulation-on, medication-off state). This study is registered with ClinicalTrials.gov, number NCT01221948. Of 53 patients enrolled in the study, 40 received a bilateral implant in the subthalamic nucleus and their data contributed to the primary endpoint analysis. Improvement was noted in the UPDRS III motor score 6 months after first lead implantation (mean 13·5 [SD 6·8], 95% CI 11·3-15·7) compared with baseline (37·4 [8·9], 34·5-40·2), with a mean difference of 23·8 (SD 10·6; 95% CI 20·3-27·3; p<0·0001). One patient died of pneumonia 24 weeks after implantation, which was judged to be unrelated to the procedure

    Full Text Available Although older people are particularly liable to sarcopenia, limited research is available on beta-hydroxy-beta-methylbutyrate (HMB supplementation in this population, particularly in healthy subjects. In this parallel-group, randomized, controlled, open-label trial, we aimed to evaluate whether an oral supplement containing 1.5 g of calcium HMB for 8 weeks could improve physical performance and muscle strength parameters in a group of community-dwelling healthy older women. Eighty healthy women attending a twice-weekly mild fitness program were divided into two equal groups of 40, and 32 of the treated women and 33 control completed the study. We considered a change in the Short Physical Performance Battery (SPPB score as the primary outcome and changes in the peak torque (PT isometric and isokinetic strength of the lower limbs, 6-minute walking test (6MWT, handgrip strength and endurance as secondary outcomes. Body composition was assessed with dual-energy X-ray absorptiometry (DXA and peripheral quantitative computerized tomography (pQCT. The mean difference between the two groups on pre-post change were finally calculated (delta for each outcome. After 8 weeks, there were no significant differences between the groups’ SPPB, handgrip strength or DXA parameters. The group treated with HMB scored significantly better than the control group for PT isokinetic flexion (delta = 1.56±1.56 Nm; p = 0.03 and extension (delta = 3.32±2.61 Nm; p = 0.03, PT isometric strength (delta = 9.74±3.90 Nm; p = 0.02, 6MWT (delta = 7.67±8.29 m; p = 0.04, handgrip endurance (delta = 21.41±16.28 s; p = 0.02, and muscle density assessed with pQCT. No serious adverse effects were reported in either group. In conclusion, a nutritional supplement containing 1.5 g of calcium HMB for 8 weeks in healthy elderly women had no significant effects on SPPB, but did significantly improve several muscle strength and physical performance parameters.ClinicalTrials.gov NCT

    As hypertension and dyslipidemia are frequent comorbidities, antihypertensive drugs and lipid-lowering agents are often prescribed together for their treatment. Telmisartan and rosuvastatin are widely used together to treat hypertension and dyslipidemia. A combination formulation of these two drugs would improve patient compliance due to ease of dosing. The purpose of this study was to assess bioequivalence of single-dose administration of a newly-developed fixed-dose combination (FDC) tablet containing telmisartan/rosuvastatin 80/20 mg (test treatment) and coadministration of a telmisartan 80-mg tablet and a rosuvastatin 20-mg tablet (reference treatment) in healthy Korean male volunteers. This was a single-dose, randomized, open-label, 2-period crossover study enrolling healthy males aged 20 - 50 years with BMI between 18.5 and 25 kg/m2. Each subject received a single dose of the reference and test treatments with a 14-day washout period. Blood sampling was performed at prespecified intervals for up to 72 hours after dosing. Primary pharmacokinetic parameters were Cmax, AUClast, and AUC0-∞ of telmisartan, rosuvastatin, and N-desmethyl rosuvastatin. Bioequivalence was assessed by determining whether the 90% confidence intervals (CIs) of the geometric mean ratios (test treatment/reference treatment) of these parameters were within the standard range of 80% to 125%. Adverse events were monitored via regular interviews with the subjects and by physical examinations. 60 subjects were enrolled and 55 completed the study. The 90% CIs of the geometric mean ratios of Cmax, AUClast, and AUC00-∞ were 0.9262-1.1498, 0.9294-1.0313, and 0.9312-1.0320 for telmisartan, 0.9041-1.0428, 0.9262-1.0085, and 0.9307-1.0094 for rosuvastatin, and 0.8718-1.0022, 0.8901-0.9904, and 0.8872-0.9767 for N-desmethyl rosuvastatin, respectively. There was no statistical difference in the incidence of adverse events (AEs) (all of which were mild or moderate) between the reference and test

    Full Text Available India is home to 60% of the total global visceral leishmaniasis (VL population. Use of long-term oral (e.g. miltefosine and parenteral drugs, considered the mainstay for treatment of VL, is now faced with increased resistance, decreased efficacy, low compliance and safety issues. The authors evaluated the efficacy and safety of an alternate treatment option, i.e. single infusion of preformed amphotericin B (AmB lipid emulsion (ABLE in comparison with that of liposomal formulation (LAmB.In this multicentric, open-label study, 500 patients with VL were randomly assigned in a 3:1 ratio to receive 15 mg/kg single infusion of either ABLE (N = 376 or LAmB (N = 124. Initial cure (Day 30/45, clinical improvement (Day 30 and long term definitive cure (Day 180 were assessed.A total of 326 (86.7% patients in the ABLE group and 122 (98.4% patients in the LAmB group completed the study. Initial cure was achieved by 95.9% of patients in the ABLE group compared to 100% in the LAmB group (p = 0.028; 95% CI: -0.0663, -0.0150. Clinical improvement was comparable between treatments (ABLE: 98.9% vs. LAmB: 98.4%. Definitive cure was achieved in 85.9% with ABLE compared to 98.4% with LAmB. Infusion-related pyrexia (37.2% vs. 32.3% and chills (18.4% vs. 18.5% were comparable between ABLE and LAmB, respectively. Treatment-related serious adverse events were fewer in ABLE (0.3% compared to LAmB (1.6%. Two deaths occurred in the ABLE group, of which one was probably related to the study drug. Nephrotoxicity and hepatotoxicity was not observed in either group.ABLE 15 mg/kg single infusion had favorable efficacy and was well tolerated. Considering the demographic profile of the population in this region, a single dose treatment offers advantages in terms of compliance, cost and applicability.www.clinicaltrials.gov NCT00876824.

    Full Text Available Simplification of antiretroviral therapy in patients with suppressed viremia may minimize long-term adverse effects. The study's primary objective was to determine whether abacavir/lamivudine + atazanavir (ABC/3TC+ATV was virologically non-inferior to tenofovir/emtricitabine + atazanavir/ritonavir (TDF/FTC+ATV/r over 24 weeks in a population of virologically suppressed, HIV-1 infected patients.This open-label, multicenter, non-inferiority study enrolled antiretroviral experienced, HIV-infected adults currently receiving a regimen of TDF/FTC+ATV/r for ≥ 6 months with no history of virologic failure and whose HIV-1 RNA had been ≤ 75 copies/mL on 2 consecutive measurements including screening. Patients were randomized 1 ∶ 2 to continue current treatment or simplify to ABC/3TC+ATV.The primary endpoint was the proportion of patients with HIV-RNA<50 copies/mL at Week 24 by the Time to Loss of Virologic Response (TLOVR algorithm. Secondary endpoints included alternative measures of efficacy, adverse events (AEs, and fasting lipids. Exploratory endpoints included inflammatory, coagulation, bone, and renal biomarkers.After 24 weeks, ABC/3TC+ATV (n = 199 was non-inferior to TDF/FTC+ATV/r (n = 97 by both the primary analysis (87% in both groups and all secondary efficacy analyses. Rates of grade 2-4 AEs were similar between the two groups (40% vs 37%, respectively, but an excess of hyperbilirubinemia made the rate of grade 3-4 laboratory abnormalities higher in the TDF/FTC+ATV/r group (30% compared with the ABC/3TC+ATV group (13%. Lipid levels were stable except for HDL cholesterol, which increased significantly in the ABC/3TC+ATV group. Bone and renal biomarkers improved significantly between baseline and Week 24 in patients taking ABC/3TC+ATV, and the difference between groups was significant at Week 24. No significant changes occurred in any inflammatory or coagulation biomarker within or between treatment groups.After 24 weeks, simplification to

    Duloxetine hydrochloride, a selective serotonin (5-HT) and norepinephrine (NE) reuptake inhibitor, is relatively balanced in its affinity for both 5-HT and NE reuptake inhibition and is the first US Food and Drug Administration-approved prescription drug for the management of diabetic peripheral neuropathic pain (DPNP). The aim of this study was to determine whether management of DPNP with duloxetine interferes with the treatment of diabetes. It also examined the tolerability of long-term exposure to duloxetine with regard to the progression of diabetic complications, and assessed the impact of DPNP management with duloxetine versus routine care. This was a 52-week, multicenter, re-randomized, open-label extension of a parallel, double-blind, randomized, placebo-controlled, acute (12-week) study. Patients who completed the duloxetine or placebo acute treatment period were randomly reassigned in a 2:1 ratio to treatment with duloxetine 60 mg BID or routine care for an additional 52 weeks. The study included male and female outpatients aged ≥18 years with a diagnosis of DPNP caused by type 1 or type 2 diabetes. Over the course of the 52-week study, visits were scheduled on the following weeks (of the extension phase of the study): 1 (via phone only), 2, 4, 8, 12, 20, 28, 40, and 52. Tolerability was assessed by review and analyses of discontinuation rates, adverse events (AEs), laboratory data, vital signs, electrocardiographic results, concomitant medications, and diabetic complications. Treatment-emergent AEs (TEAEs) were defined as AEs that appeared during therapy (were not present at baseline) or were exacerbated during treatment. Data on AEs and concomitant medications were collected at every visit. Data on blood pressure, heart rate, and significant hypoglycemic events were collected at every visit starting from week 2. Fasting clinical chemistry and electrolyte group laboratory assessments were done at every visit, starting from week 4. Electrocardiographic

    The primary aim of this study was to evaluate whether there was clinically significant pharmacokinetic (PK) interaction between finasteride and tamsulosin in healthy Chinese male subjects. This was an open-label, randomized, 3-period, crossover study. Subjects received single and multiple doses of 5 mg finasteride alone, single and multiple doses of 0.2 mg tamsulosin hydrochloride sustained-release capsule alone, and single and multiple doses of 5 mg finasteride with 0.2 mg tamsulosin hydrochloride, in an order determined by a computerized randomization schedule. Blood samples were collected up to 48 hours after dosing on study day 1 and up to 24 hours after dosing on study day 9 for determination of plasma concentrations with a validated LC-MS/MS method. Pharmacokinetic parameters were estimated via noncompartmental methods. Tolerability was evaluated by monitoring adverse events, laboratory assays, vital signs, and 12-lead ECG. Fifteen subjects were enrolled, and 14 completed the study. The geometric mean ratios (GMRs) (90% CIs) of AUC(τ,ss) and C(max,ss) values of finasteride at steady state between coadministration of finasteride and tamsulosin hydrochloride and finasteride alone were 1.14 (1.05-1.23) and 1.06 (0.99-1.14), respectively. The GMRs (90% CIs) for AUC(0-t) and C(max) values of finasteride for a single dose of coadministration of finasteride and tamsulosin hydrochloride and finasteride alone were 1.02 (0.94-1.11) and 1.06 (1.01-1.11), respectively. The GMRs (90% CIs) for AUC(τ,ss) and C(max,ss) values of tamsulosin at steady-state for coadministration of finasteride and tamsulosin hydrochloride and tamsulosin hydrochloride alone were 1.18 (1.05-1.33) and 1.23 (1.06-1.43), respectively. The GMRs (90% CIs) for AUC(0-t) and C(max) values of tamsulosin for a single dose of coadministration of finasteride and tamsulosin hydrochloride and tamsulosin hydrochloride alone were 1.04 (0.97-1.10) and 1.04 (0.98-1.11), respectively.

    Omeprazole is a proton-pump inhibitor that acts to reduce acid secretion in the stomach and is used for treating various acid-related gastrointestinal disorders. There are several generic formulations of omeprazole available in Mexico; however, a literature search failed to identify published data concerning the bioavailability of these formulations in the Mexican population. The aim of this study was to compare the bioavailability of 2 oral formulations of omeprazole 20-mg capsules, marketed for use in Mexico, in healthy volunteers: Inhibitron (test formulation) and LosecA 20 mg (reference formulation). This study used a single-dose, open-label, randomized sequence, 2 x 2 crossover (2 administration periods x 2 treatments) design to compare the 2 formulations. Eligible subjects were healthy adult Mexican volunteers of both sexes. Subjects were randomly assigned in a 1:1 ratio to receive a single 20-mg dose of the test formulation followed by the reference formulation, or vice versa, with a 7-day washout period between administration periods. After a 12-hour (overnight) fast, subjects received a single, 20-mg dose of the corresponding formulation. Plasma samples were obtained over a 12-hour period after administration. Plasma omeprazole concentrations were analyzed by a nonstereospecific high-performance liquid chromatography method. For analysis of pharmacokinetic properties, including C(max), AUC from time 0 (baseline) to time t (AUC(0-t)), and AUC from baseline to infinity (AUC(0-infinity)), blood samples were drawn at baseline and 0.17, 0.33, 0.50, 0.75, 1, 1.25, 1.50, 1.75, 2, 2.50, 3, 4, 6, 8, and 12 hours after administration. The formulations were considered bioequivalent if the natural log (ln)-transformed ratios of C(max) and AUC were within the predetermined equivalence range of 80% to 125%, and if P disability, or required intervention to prevent permanent impairment or damage. Thirty-four subjects were enrolled and completed the study (25 men and 9

    We investigated the effectiveness and tolerability of aripiprazole in the treatment of irritability in Asian children and adolescents (6-17 years) with autistic disorder in a 12-week, multinational, multicenter, open-label study. Sixty-seven subjects (10.0 ± 3.1 years old, 52 boys) were enrolled and treated with flexibly dosed aripiprazole for 12 weeks (mean dose, 5.1 ± 2.5 mg; range 2-15 mg). Aripiprazole significantly reduced the mean caregiver-rated scores for the Irritability, Lethargy/Social Withdrawal, Stereotypy, Hyperactivity, and Inappropriate Speech subscales of the Aberrant Behavior Checklist from baseline to week 12 (p autistic disorder. Further studies with larger sample sizes and longer treatment durations are required.

    Artemether-lumefantrine (Coartem; AL) is a standard of care for malaria treatment as an oral six-dose regimen, given twice daily over three days with one to four tablets (20/120 mg) per dose, depending on patient body weight. In order to reduce the pill burden at each dose and potentially enhance compliance, two novel fixed-dose tablet formulations (80/480 mg and 60/360 mg) have been developed and tested in this study for bioequivalence with their respective number of standard tablets. A randomized, open-label, two-period, single-dose, within formulation crossover bioequivalence study comparing artemether and lumefantrine exposure between the novel 80/480 mg tablet and four standard tablets, and the novel 60/360 mg tablet and three standard tablets, was conducted in 120 healthy subjects under fed conditions. Artemether, dihydroartemisinin, and lumefantrine were measured in plasma by HPLC/UPLC-MS/MS. Pharmacokinetic (PK) parameters were determined by non-compartmental analyses. Adjusted geometric mean AUClast for artemether were 345 and 364 ng·h/mL (geometric mean ratio (GMR) 0.95; 90% CI 0.89-1.01) and for lumefantrine were 219 and 218 μg·h/mL (GMR 1.00; 90% CI 0.93-1.08) for 80/480 mg tablet versus four standard tablets, respectively. Corresponding Cmax for artemether were 96.8 and 99.7 ng/mL (GMR 0.97; 90% CI 0.89-1.06) and for lumefantrine were 8.42 and 8.71 μg/mL (GMR 0.97; 90% CI 0.89-1.05). For the 60/360 mg tablet versus three standard tablets, adjusted geometric mean AUClast for artemether were 235 and 231 ng·h/mL (GMR 1.02; 90% CI 0.94-1.10), and for lumefantrine were 160 and 180 μg·h/mL (GMR 0.89; 90% CI 0.83-0.96), respectively. Corresponding Cmax for artemether were 75.5 and 71.5 ng/mL (GMR 1.06; 90% CI 0.95-1.18), and for lumefantrine were 6.64 and 7.61 μg/mL (GMR 0.87; 90% CI 0.81-0.94), respectively. GMR for Cmax and AUClast for artemether and lumefantrine for all primary comparisons were within the bioequivalence acceptance criteria (0

    Bepotastine is a second-generation histamine1 receptor antagonist that is used in the treatment of allergic rhinitis, urticaria, and pruritus associated with skin disease. A new generic formulation of bepotastine has been developed in China, and information concerning bioavailability and pharmacokinetic properties in the Chinese population has not been reported. The aim of the present study was to compare the bioavailability and pharmacokinetic properties of 2 tablet formulations of bepotastine, the 10-mg generic formulation (test) and a branded formulation (reference), in healthy male Chinese volunteers to obtain registration approval of the test formulation. A single-center, open-label, randomized, 2-way crossover study with a 1-week washout period was conducted in 24 healthy male volunteers. Blood samples were collected for 16 hours after a single dose of the 10-mg bepotastine test formulation or the reference formulation. Plasma bepotastine concentrations were determined using a validated LC-MS/MS method. Cmax, Tmax, AUC₀-t, AUC₀-∞, and t½ were determined using noncompartmental analysis. The formulations were considered bioequivalent if the 90% CIs for the log-transformed Cmax and AUC values were within the predetermined interval of 75% to 133% and 80% to 125%, respectively, according to the guidelines of the China Food and Drug Administration. No significant differences were found in mean (SD) pharmacokinetic parameters between the test and reference drugs, including Cmax (74.81 [9.91] ng/mL vs 78.60 [29.58] ng/mL), AUC₀-t (295.55[115.29] ng·h/mL vs 299.17[109.29] ng·h/mL), and AUC0-∞ (305.28 [118.50] ng·h/mL vs 310.90 [112.20] ng·h/mL). The mean (SD) t½ values of the test and reference formulations were 2.53 (0.50) hours and 2.62 (0.41) hours, respectively. The 90% CIs of the treatment ratios for the logarithmic transformed values of Cmax, AUC₀-t, and AUC₀-∞ were 86.96% to 101.80%, 93.22% to 104.13%, and 92.66% to 103.30%, respectively

    Objective Intravenous belimumab 10 mg/kg is approved as an add-on therapy in patients with active, autoantibody-positive systemic lupus erythematosus. This study aimed to assess the impact of belimumab on immune response to pneumococcal vaccination in patients with systemic lupus erythematosus. Methods This was a Phase 4, open-label study (GSK BEL115470; NCT01597492) conducted in the United States. Patients were randomized (7:9) to receive a 23-valent pneumococcal vaccination four weeks prior to (pre-belimumab cohort) or 24 weeks after (belimumab-concurrent cohort) commencing four-weekly belimumab 10 mg/kg intravenous treatment plus standard systemic lupus erythematosus therapy. Analyses of vaccine titers were performed on the as-treated population (received ≥1 dose of belimumab). The primary endpoint was the proportion of patients with positive antibody responses (≥2-fold increase from pre-vaccination levels, or post-vaccination level ≥ 0.6 µg/mL if pre-vaccination levels were unquantifiable) to ≥1 of 23 pneumococcal vaccine serotypes, four weeks post vaccination. Other endpoints included the proportion of patients with positive antibody responses to ≥2 to ≥10, and ≥11-23 (post hoc analysis) of serotypes. Safety was assessed by monitoring adverse events. Results Seventy-nine patients received pneumococcal vaccination (pre-belimumab cohort, n = 34; belimumab-concurrent cohort, n = 45). The majority (87.3% [69/79]) completed the study; 10 (12.7%) withdrew (patient request, n = 3; adverse event, n = 3; lost to follow-up, n = 2; other, n = 2). At Week 4 post-vaccination, 97.0% (32/33) and 97.6% (40/41) of patients (pre-belimumab and concurrent belimumab cohorts, respectively) had a positive response to ≥1 of 23 pneumococcal serotypes. Over 85% of patients in both cohorts responded to ≥10 of serotypes, approximately 80% responded to ≥12 serotypes, and approximately two-thirds responded to ≥16 serotypes. Little

    PEG-rhG-CSF reduces neutropenia and improves chemotherapy safety. In China's registration trial (CFDA: 2006L01305), we assessed its efficacy and safety against rhG-CSF, and prospectively explored its value over multiple cycles of chemotherapy. In this open-label, randomized, multicenter phase 3 study, breast cancer patients (n = 569) were randomized to receive PEG-rhG-CSF 100 µg/kg, PEG-rhG-CSF 6 mg, or rhG-CSF 5 µg/kg/d after chemotherapy. The primary endpoints were the incidence and duration of grade 3/4 neutropenia during cycle 1. Secondary endpoints included the incidence and duration of grade 3/4 neutropenia during cycles 2-4, the incidence of febrile neutropenia, and the safety. A once-per-cycle PEG-rhG-CSF at either 100 µg/kg or 6 mg was not different from daily injections of rhG-CSF for either incidence or duration of grade 3/4 neutropenia. Interestingly, a substantial difference was noted during cycle 2, and the difference became bigger over cycles 3-4, reaching a statistical significance at cycle 4 in either incidence (P = 0.0309) or duration (P = 0.0289) favoring PEG-rhG-CSF. A significant trend toward a lower incidence of all-grade adverse events was noted at 129 (68.98%), 142 (75.53%), and 160 (82.47%) in the PEG-rhG-CSF 100 µg/kg and 6 mg and rhG-CSF groups, respectively (P = 0.0085). The corresponding incidence of grade 3/4 drug-related adverse events was 2/187 (1.07%), 1/188 (0.53%), and 8/194 (4.12%), respectively (P = 0.0477). Additionally, PFS in metastatic patients preferred PEG-rhG-CSF to rhG-CSF despite no significance observed by Kaplan-Meier analysis (n = 49, P = 0.153). PEG-rhG-CSF is a more convenient and safe formulation and a more effective prophylactic measure in breast cancer patients receiving multiple cycles of chemotherapy.

    Faldaprevir (FDV) is a potent, orally administered inhibitor of hepatitis C virus protease. It inhibits multiple cytochrome P-450 enzymes and multiple membrane transporters. The objective of this study was to evaluate the effect of steady-state faldaprevir on the pharmacokinetics (PK) of a single dose of atorvastatin or rosuvastatin. In this single-center, open-label, fixed-sequence crossover study, 33 healthy adult male and female volunteers were given either atorvastatin 10 mg (n = 16) or rosuvastatin 10 mg (n = 17) on day 1. Subjects subsequently received 240 mg twice daily of faldaprevir (loading dose) on day 5, followed by 240 mg faldaprevir once daily from day 6 to day 10, with an additional single dose of atorvastatin (10 mg) or rosuvastatin (10 mg) given on day 10. PK samples for the statins were collected on days 1-3 and days 10-12. Concomitant administration with faldaprevir led to approximately 9-fold and 34-fold increases in AUC 0-∞ and C max , respectively, of atorvastatin and approximately 15-fold and 33-fold increases in AUC 0-∞ and C max , respectively, of rosuvastatin, compared with the statins given alone. Exposure to the major metabolites (ortho-hydroxyatorvastatin and N-desmethylrosuvastatin) was increased to a similar magnitude as that of the parent compounds. The marked drug-drug interaction observed is most likely related to the inhibitory effects of faldaprevir on transporters, particularly hepatic uptake transporters such as OTAP1B1 and OATP1B3. Given the significant increase in exposure to statins in healthy volunteers, coadministration of faldaprevir with statins should be avoided. © 2017, The American College of Clinical Pharmacology.

    The purpose of this study was to examine the impact of stimulant treatment on risk for alcohol and illicit drug use in adolescents with ADHD. Analysis of data derived from a prospective open-label treatment study of adolescent ADHD ( n = 115, 76% male), and a historical, naturalistic sample of ADHD ( n = 44, 68% male) and non-ADHD youth ( n = 52, 73% male) of similar age and sex. Treatment consisted of extended-release methylphenidate in the clinical trial or naturalistic stimulant treatment. Self-report of alcohol and drug use was derived from a modified version of the Drug Use Screening Inventory. Rates of alcohol and drug use in the past year were significantly lower in the clinical trial compared with untreated and treated naturalistic ADHD comparators, and similar to rates in non-ADHD comparators. Well-monitored stimulant treatment may reduce the risk for alcohol and substance use in adolescent ADHD.

    Full Text Available William Eardley, Cory TothDepartment of Clinical Neurosciences and the University of Calgary, Calgary, AB, CanadaAbstract: Although many therapies are used in the management of neuropathic pain (NeP due to polyneuropathy (PN, few comparison studies exist. We performed a prospective, non-randomized, unblended, efficacy comparison of the serotonin-norepinephrine reuptake inhibitor venlafaxine, as either monotherapy or adjuvant therapy, with a first-line medication for NeP, gabapentin, in patients with PN-related NeP. VAS pain scores were assessed after 3 and 6 months in intervention groups and in a cohort of patients receiving no pharmacotherapy. In a total of 223 patients, we analyzed pain quantity and quality (visual analogue scale [VAS] score, Brief Pain Inventory [BPI], quality of life and health status measures [EuroQol 5 Domains, EQ-5D], Medical Outcomes Sleep Study Scale [MOSSS], Hospital Anxiety and Depression Scale [HADS] and Short Form 36 Health Survey [SF-36] after 6 months of therapy. Significant improvements in VAS pain scores occurred for all treatment groups after 6 months. Improvements in aspects of daily life and anxiety were identified in all treatment groups. Our data suggest that monotherapy or adjuvant therapy with venlafaxine is comparable to gabapentin for NeP management. We advocate for head-to-head, randomized, double-blinded studies of current NeP therapies.Keywords: peripheral neuropathy, neuropathic pain, pharmacotherapy, venlafaxine, gabapentin

    To investigate the intra-ocular pressure (IOP)-lowering effects of a selective Rho kinase inhibitor, ripasudil (K-115), over 24 hr in patients with primary open-angle glaucoma (POAG) or ocular hypertension (OHT). In this multicenter, prospective, randomized, open-label, 3-period, Latin-square crossover clinical study, 28 patients with POAG or OHT whose IOP level was 21 mmHg or higher were subdivided into three groups. Each patient was treated with placebo and ripasudil in concentrations of 0.2 and 0.4%, at 9:00 and 21:00 on day 1 through a total of 3 periods separated by washout periods. IOP was measured at 9:00, 10:00, 11:00, 13:00, 16:00, 19:00, 21:00, 22:00 and 23:00 on day 1, and 1:00, 4:00, 7:00 and 9:00 on day 2 in sitting position using Goldmann applanation tonometer. Main outcome measure was the IOP reduction of placebo and ripasudil from baseline. The mean IOP reduction was -5.2 mmHg for 0.2%, -6.4 mmHg for 0.4% and -2.0 mmHg for placebo at 2 hr after the first instillation. Also, the corresponding values were -6.8 mmHg for 0.2%, -7.3 mmHg for 0.4% and -4.1 mmHg for placebo at 2 hr after the second instillation. Statistically significant IOP reduction, compared with placebo, was found for both 0.2 and 0.4% from 1 through 7 hr after each instillation. In safety, conjunctival hyperaemia was observed in 22 patients (79%) for 0.2%, 27 patients (96%) for 0.4% and three patients (11%) for placebo. Ripasudil is a promising new topical medication to lower IOP for at least 7 hr after instillations in patients with POAG or OHT. © 2014 Acta Ophthalmologica Scandinavica Foundation.

    We examined the efficacy and safety of saxagliptin as an add-on to insulin in Japanese patients with type 2 diabetes mellitus. We randomized 240 patients with type 2 diabetes mellitus on insulin monotherapy to 5-mg saxagliptin or placebo as add-on therapy for a 16-week, double-blind period. All patients received 5-mg saxagliptin and insulin for an additional 36 weeks (open-label extension). Change in hemoglobin A1c (HbA1c) at Week 16 was the main endpoint. At Week 16, the adjusted change in HbA1c from baseline increased by 0.51% with placebo and decreased by 0.40% with saxagliptin (difference -0.92% [95% confidence interval -1.07%, -0.76%; p 1]). In patients receiving saxagliptin, reductions in HbA1c at Week 16 were maintained to Week 52, while switching from placebo to saxagliptin resulted in a similar reduction in HbA1c. The incidence of hypoglycemia was not markedly increased with saxagliptin versus placebo in the double-blind period and did not increase substantially during the open-label extension period. The efficacy and safety of saxagliptin was similar between the elderly and non-elderly patient groups. Adding saxagliptin to ongoing insulin therapy improved glycemic control and was well tolerated in Japanese patients with type 2 diabetes.

    Episodic breathlessness is a frequent and burdensome symptom in cancer patients but pharmacological treatment is limited. To determine time to onset, efficacy, feasibility, and safety of transmucosal fentanyl in comparison to immediate-release morphine for the relief of episodic breathlessness. Phase II, investigator-initiated, multicenter, open-label, randomized, morphine-controlled, crossover trial with open-label titration of fentanyl buccal tablet (FBT) in inpatients with incurable cancer. The primary outcome was time to onset of meaningful breathlessness relief. Secondary outcomes were efficacy (breathlessness intensity difference at 10 and 30 minutes; sum of breathlessness intensity difference at 15 and 60 minutes), feasibility, and safety. Study was approved by local ethics committees. Twenty-five of 1341 patients were eligible, 10 patients agreed to participate (four female, mean age 58 ± 11, mean Karnofsky score 67 ± 11). Two patients died before final visits and two patients dropped-out because of disease progression leaving six patients for analysis with 61 episodes of breathlessness. Mean time to onset was for FBT 12.7 ± 10.0 and for immediate-release morphine 23.6 ± 15.1 minutes with a mean difference of -10.9 minutes (95% CI = -24.5 to 2.7, P = 0.094). Efficacy measures were predominately in favor for FBT. Both interventions were safe. Feasibility failed because of too much study demands for a very ill patient group. The description of a faster and greater relief of episodic breathlessness by transmucosal fentanyl versus morphine justifies further evaluation by a full-powered trial. Copyright © 2016.

    The aim of this study was to evaluate the safety and efficacy of the early administration haloperidol in preventing the aggravation of postoperative delirium in elderly patients. A total of 201 patients (age ≥75 years) who underwent elective surgery were enrolled. The patients were divided into two groups: the intervention group (n = 101) received prophylactic haloperidol (5 mg); the control group (n = 100) did not. Haloperidol was administered daily during postoperative days 0-5 to the patients who presented with NEECHAM scores of 20-24 when measured at 18:00. The primary endpoint was the incidence of severe postoperative delirium. The incidence of severe postoperative delirium in all patients was 25.1%. The incidence of severe postoperative delirium in the intervention group (18.2%) was significantly lower than that in the control group (32.0%) (p = 0.02). The difference between the two groups was larger when the analysis was limited to the 70 patients who had NEECHAM scores of 20-24 for at least one day during postoperative days 0-5. No adverse effects of the haloperidol were observed. The prophylactic administration of haloperidol at the early stage of delirium significantly reduced the incidence of severe postoperative delirium in elderly patients.

    The aims of this study were to determine whether disposition-related pharmacokinetic parameters such as T(max) and mean residence time (MRT) could be used as predictors of clinical efficacy of tacrolimus in renal transplant recipients, and to what extent these parameters would be influenced by clinical variables. We previously demonstrated, in a prospective pharmacokinetic study in de novo renal allograft recipients, that patients who experienced early acute rejection did not differ from patients free from rejection in terms of tacrolimus pharmacokinetic exposure parameters (dose interval AUC, preadministration trough blood concentration, C(max), dose). However, recipients with acute rejection reached mean (SD) tacrolimus T(max) significantly faster than those who were free from rejection (0.96 [0.56] hour vs 1.77 [1.06] hours; P clearance nor T(1/2) could explain this unusual finding, we used data from the previous study to calculate MRT from the concentration-time curves. As part of the previous study, 100 patients (59 male, 41 female; mean [SD] age, 51.4 [13.8] years;age range, 20-75 years) were enrolled in the study The calculated MRT was significantly shorter in recipients with acute allograft rejection (11.32 [031] hours vs 11.52 [028] hours; P = 0.02), just like T(max) was an independent risk factor for acute rejection in a multivariate logistic regression model (odds ratio, 0.092 [95% CI, 0.014-0.629]; P = 0.01). Analyzing the impact of demographic, transplantation-related, and biochemical variables on MRT, we found that increasing serum albumin and hematocrit concentrations were associated with a prolonged MRT (P calculated MRT were associated with a higher incidence of early acute graft rejection. These findings suggest that a shorter transit time of tacrolimus in certain tissue compartments, rather than failure to obtain a maximum absolute tacrolimus blood concentration, might lead to inadequate immunosuppression early after transplantation.

    Objective: To determine if pro-inflammatory and pro-thrombotic biomarkers are differentially upregulated in persistently antiphospholipid antibody (aPL)-positive patients, and to examine the effects of fluvastatin on these biomarkers. Methods: Four groups of patients (age 18-65) were recruited: a) Primary Antiphospholipid Syndrome (PAPS); b) Systemic Lupus Erythematosus (SLE) with APS (SLE/APS); c) Persistent aPL positivity without SLE or APS (Primary aPL); and d) Persistent aPL positivity with SLE but no APS (SLE/aPL). The frequency-matched control group, used for baseline data comparison, was identified from a databank of healthy persons. Patients received fluvastatin 40 mg daily for three months. At three months, patients stopped the study medication and they were followed for another three months. Blood samples for 12 pro-inflammatory and pro-thrombotic biomarkers were collected monthly for six months. Results: Based on the comparison of the baseline samples of 41 aPL-positive patients with 30 healthy controls, 9/12 (75%) biomarkers (interleukin [IL]-6, IL1β, vascular endothelial growth factor [VEGF], tumor necrosis factor [TNF]-□α, interferon [IFN]-α, inducible protein-10 [IP10], soluble CD40 ligand [sCD40L], soluble tissue factor [sTF], and intracellular cellular adhesion molecule [ICAM]-1) were significantly elevated. Twenty-four patients completed the study; fluvastatin significantly and reversibly reduced the levels of 6/12 (50%) biomarkers (IL1β, VEGF, TNFα, IP10, sCD40L, and sTF). Conclusion: Our prospective mechanistic study demonstrates that pro-inflammatory and pro-thrombotic biomarkers, which are differentially upregulated in persistently aPL-positive patients, can be reversibly reduced by fluvastatin. Thus, statin-induced modulation of the aPL effects on target cells can be a valuable future approach in the management of aPL-positive patients. PMID:23933625

    The effects of tamsulosin treatment on changes in frequency-volume chart (FVC) data, especially nighttime urine production, over time were assessed, and the mechanisms underlying the improvement of nocturia in benign prostatic hyperplasia (BPH) patients with nocturnal polyuria (NP) are discussed. A total of 104 patients with lower urinary tract symptoms secondary to BPH were enrolled. After enrollment in the study, the patients were treated with tamsulosin (0.2 mg) once daily. Visits were scheduled every 4 weeks until week 12 (month 3) after study entry, and then every 12 weeks subsequently. All patients completed the International Prostate Symptom Score (IPSS), quality of life (QOL) index, and 3-day FVC, and underwent uroflowmetry at enrollment and on each visit. Eighty-two patients (mean age: 70.9 ± 7.1 years) were analyzed for 24 months after treatment. Patients were divided into two groups, NP and nonNP, based on FVC outcome. The IPSS, QOL index, and maximum flow rate improved during the 24-month period after treatment in both groups. Mean daytime urine volume significantly increased in the NP group, but no changes were detected in the nonNP group. Mean nighttime urine frequency significantly decreased in the NP group over a 24-month period, and was associated with a significant decrease in nighttime urine volume that was not found in the nonNP group. Maximum voided volume increased most months after treatment in both groups. The present long-term prospective study using FVC demonstrated that tamsulosin reduced nighttime urine production in BPH patients with NP. Copyright © 2011 Wiley Periodicals, Inc.

    This study aimed to evaluate whether selecting mirtazapine as the first choice for current depressive episode instead of selective serotonin reuptake inhibitors (SSRIs) reduces benzodiazepine use in patients with major depressive disorder (MDD). We concurrently examined the relationship between clinical responses and serum mature brain-derived neurotrophic factor (BDNF) and its precursor, proBDNF. We conducted an open-label randomized trial in routine psychiatric practice settings. Seventy-seven MDD outpatients were randomly assigned to the mirtazapine or predetermined SSRIs groups, and investigators arbitrarily selected sertraline or paroxetine. The primary outcome was the proportion of benzodiazepine users at weeks 6, 12, and 24 between the groups. We defined patients showing a ≥50 % reduction in Hamilton depression rating scale (HDRS) scores from baseline as responders. Blood samples were collected at baseline, weeks 6, 12, and 24. Sixty-five patients prescribed benzodiazepines from prescription day 1 were analyzed for the primary outcome. The percentage of benzodiazepine users was significantly lower in the mirtazapine than in the SSRIs group at weeks 6, 12, and 24 (21.4 vs. 81.8 %; 11.1 vs. 85.7 %, both P  depressive episodes may reduce benzodiazepine use in patients with MDD. Trial registration UMIN000004144. Registered 2nd September 2010. The date of enrolment of the first participant to the trial was 24th August 2010. This study was retrospectively registered 9 days after the first participant was enrolled.

    Full Text Available Adolescents are in a high-risk period developmentally, in terms of susceptibility to stress. A mindfulness intervention represents a potentially useful strategy for developing cognitive and emotion regulation skills associated with successful stress coping. Mindfulness strategies have been used successfully for emotional coping in adults, but are not as well studied in youth. This article details a novel proposal for the design of an 8-week randomized study to evaluate a high school-based mindfulness curriculum delivered as part of a two semester health class. A wellness education intervention is proposed as an active control, along with a waitlist control condition. All students enrolled in a sophomore (10th grade health class at a private suburban high school will be invited to participate (n = 300. Pre-test assessments will be obtained by youth report, parent ratings, and on-site behavioral testing. The assessments will evaluate baseline stress, mood, emotional coping, controlled attention, and working memory. Participants, divided into 13 classrooms, will be randomized into one of three conditions, by classroom: A mindfulness intervention, an active control (wellness education, and a passive control (waitlist. Waitlisted participants will receive one of the interventions in the following term. Intervention groups will meet weekly for 8 weeks during regularly scheduled health classes. Immediate post-tests will be conducted, followed by a 60-day post-test. It is hypothesized that the mindfulness intervention will outperform the other conditions with regard to the adolescents' mood, attention and response to stress.

    Full Text Available Aim: To compare the efficacy and safety of omeprazole-domperidone combination vs omeprazole monotherapy in gastroesophageal reflux disease (GERD. Methods: In a comparative, randomized controlled, phase 4 study, outpatients with GERD were randomly allocated to either group 1 (omeprazole 20 mg + domperidone 30 mg or group 2 (omeprazole 20 mg in an equal ratio; 2 capsules daily in the morning were administered for 8 weeks. Results: Sixty patients were enrolled. Esophagitis reversal was observed in 92% patients in group 1 vs 65.2% in group 2. Approximately, 83.3% patients in group 1 vs 43.3% patients in group 2 demonstrated full cupping of reflux symptoms at 8 weeks. Combined therapy resulted in significantly longer period of heartburn-free days (23 vs 12 days on omeprazole. There were no safety concerns. Conclusions: Omeprazole-domperidone combination was more effective than omeprazole alone in providing complete cupping of reflux symptoms and healing of esophagitis in patients with GERD. Both the treatments were well tolerated with few reports of adverse events. Trial registration: This trial is registered with http://clinicaltrials.gov , number NCT02140073.

    The aim of this study was to compare the tolerability and efficacy of once-daily travoprost 0.004% versus latanoprost 0.005% for 6 weeks followed by 6 weeks of once-daily travoprost 0.004% in decreasing intraocular pressure (IOP) in patients with open-angle glaucoma (OAG) or ocular hypertension (OH). This multicenter, randomized, doublemasked, active-controlled, parallel-group trial was conducted at 32 centers across Latin America. Patients aged > or =18 years with OAG or OH were randomly assigned to receive topical travoprost 0.004% or latanoprost 0.005% 1 drop QD (9 PM) for 6 weeks (masked phase). At 6 weeks, all patients were assigned to receive open-label travoprost 0.004% 1 drop QD (9 PM) for 6 additional weeks (open-label phase). Study visits were scheduled at weeks 1, 2, 4, 6, 8, and 12. At each study visit, IOP was measured at 5 PM (+/-1 hour; approximately 20 hours after study drug administration). IOP changes from baseline were combined (pooled) from the 1-, 2-, 4-, and 6-week data to provide a comparison between the 2 treatment groups. Ocular adverse events (AEs) were monitored using slit-lamp examination. A total of 302 patients were enrolled (travoprost group, 155 patients; latanoprost group, 147 patients). The mean (SD) age of the travoprost group was 61.9 (10.6) years; 60.6% were female; and 47.1% were white. The mean (SD) age of the latanoprost group was 60.5 (12.4) years; 62.6% were female; and 49.0% were white. Mean IOP values were not significantly different between the travoprost and latanoprost groups at baseline (24.7 vs 24.2 mm Hg) or 6 weeks; however, the between-group difference in reductions from baseline in pooled IOP during the masked phase of the study was statistically significant (-8.3 vs -7.5 mm Hg; P = 0.009). At weeks 6 and 12, mean lOP levels were 16.1 and 16.2 mm Hg, respectively, in the travoprost group and 16.4 and 16.1 mm Hg in the group that was switched from latanoprost to travoprost (all, P = NS).

    Purpose Until recently, limited options existed for patients with advanced melanoma who experienced disease progression while receiving treatment with ipilimumab. Here, we report the coprimary overall survival (OS) end point of CheckMate 037, which has previously shown that nivolumab resulted in more patients achieving an objective response compared with chemotherapy regimens in ipilimumab-refractory patients with advanced melanoma. Patients and Methods Patients were stratified by programmed death-ligand 1 expression, BRAF status, and best prior cytotoxic T-lymphocyte antigen-4 therapy response, then randomly assigned 2:1 to nivolumab 3 mg/kg intravenously every 2 weeks or investigator's choice chemotherapy (ICC; dacarbazine 1,000 mg/m 2 every 3 weeks or carboplatin area under the curve 6 plus paclitaxel 175 mg/m 2 every 3 weeks). Patients were treated until they experienced progression or unacceptable toxicity, with follow-up of approximately 2 years. Results Two hundred seventy-two patients were randomly assigned to nivolumab (99% treated) and 133 to ICC (77% treated). More nivolumab-treated patients had brain metastases (20% v 14%) and increased lactate dehydrogenase levels (52% v 38%) at baseline; 41% of patients treated with ICC versus 11% of patients treated with nivolumab received anti-programmed death 1 agents after randomly assigned therapy. Median OS was 16 months for nivolumab versus 14 months for ICC (hazard ratio, 0.95; 95.54% CI, 0.73 to 1.24); median progression-free survival was 3.1 months versus 3.7 months, respectively (hazard ratio, 1.0; 95.1% CI, 0.78 to 1.436). Overall response rate (27% v 10%) and median duration of response (32 months v 13 months) were notably higher for nivolumab versus ICC. Fewer grade 3 and 4 treatment-related adverse events were observed in patients on nivolumab (14% v 34%). Conclusion Nivolumab demonstrated higher, more durable responses but no difference in survival compared with ICC. OS should be interpreted with

    Full Text Available To examine the effect of sildenafil on erectile dysfunction (ED and psychosocial outcomes in alcohol-dependent (AD men, 108 men with these diagnoses were randomly assigned to either take sildenafil (50 mg as add-on to standard treatment for AD, or the same treatment without sildenafil, for 12 weeks. Only 50 patients in sildenafil group and 51 in control group twice completed the International Index of Erectile Function (IIEF and a battery of self-report questionnaires. IIEF scores and psychosocial functioning, self-esteem and support from friends improved only for sildenafil-treated patients (P < 0.001. The high effect sizes suggest that the observed benefits are unlikely to be a placebo effect, although their unspecific nature could not be ruled out. In men with ED associated with AD, sildenafil improves both ED and psychosocial outcomes. Further placebo-controlled clinical trial is warranted.

    Identification of optimal surgical site antisepsis preparations may reduce cesarean-related surgical site infections. Two recently published investigations examined efficacy of chlorhexidine-alcohol and iodine-alcohol preparations. No previous randomized controlled trial has compared chlorhexidine-alcohol to povidone-iodine aqueous scrub and paint in reduction of cesarean-related surgical site infection. The purpose of the study was to determine if chlorhexidine-alcohol would result in fewer surgical site infections than povidone-iodine when used as skin antisepsis preparation prior to cesarean delivery. This study was a single-center pragmatic randomized controlled trial at an urban tertiary care institution to compare chlorhexidine-alcohol 26-mL single-step applicator to povidone-iodine aqueous scrub and paint 236-mL wet skin tray as preoperative skin antiseptic preparation for women undergoing cesarean delivery. Patients were eligible for study participation if they could provide informed consent in English or Spanish, were ≥18 years of age, did not have clinical chorioamnionitis, were unlikely to be lost to follow-up, and had no sensitivities to chlorhexidine, betadine, or iodine. Treatment was assigned by computer-generated simple 1:1 randomization immediately before skin preparation. The primary outcome was surgical site infection occurring within 30 days of cesarean delivery including ≥1 of: superficial or deep surgical site infection, or endometritis, according to Centers for Disease Control and Prevention definitions. Analysis was by intent to treat. Categorical outcomes were compared using Fisher exact test. The Wilcoxon rank-sum test was performed for continuous outcomes. This trial was institutional review board approved and registered at ClinicalTrials.gov (NCT02202577). In all, 932 subjects (461 assigned to chlorhexidine-alcohol, 471 assigned to povidone-iodine) were randomized from February 2013 through May 2016. Rate of follow-up evaluation

    Influenza remains a significant problem in elderly despite widespread vaccination coverage. This randomized, phase-I study in elderly compared different strategies of improving vaccine immunogenicity. A total of 370 healthy participants (⩾65years) were randomized equally 1:1:1:1:1:1 to six influenza vaccine treatments (approximately 60-63 participants per treatment arm) at day 1 that consisted of three investigational virosomal vaccine formulations at doses of 7.5, 15, and 45μg HA antigen/strain administered intradermally (ID) by MicronJet600™ microneedle device (NanoPass Technologies) or intramuscularly (IM), and three comparator registered seasonal vaccines; Inflexal V™ (Janssen) and MF59 adjuvanted Fluad™ (Novartis) administered IM and Intanza™ (Sanofi Pasteur) administered ID via Soluvia™ prefilled microinjection system (BD). Serological evaluations were performed at days 22 and 90 and safety followed-up for 6months. Intradermal delivery of virosomal vaccine using MicronJet600™ resulted in significantly higher immunogenicity than the equivalent dose of virosomal Inflexal V™ administered intramuscularly across most of the parameters and strains, as well as in some of the readouts and strains as compared with the 45μg dose of virosomal vaccine formulation. Of 370 participants, 300 (81.1%) reported ⩾1 adverse event (AE); more participants reported solicited local AEs (72.2%) than solicited systemic AEs (12.2%). Intradermal delivery significantly improved influenza vaccine immunogenicity compared with intramuscular delivery. Triple dose (45μg) virosomal vaccine did not demonstrate any benefit on vaccine's immunogenicity over 15μg commercial presentation. All treatments were generally safe and well-tolerated.

    To compare the failure rates between Jet continuous positive airway pressure device (J-CPAP-variable flow) and Bubble continuous positive airway device (B-CPAP) in preterm infants with respiratory distress. Preterm newborns CPAP (a variable flow device) or B-CPAP (continuous flow device). A standardized protocol was followed for titration, weaning and removal of CPAP. Pressure was monitored close to the nares in both the devices every 6 hours and settings were adjusted to provide desired CPAP. The primary outcome was CPAP failure rate within 72 h of life. Secondary outcomes were CPAP failure within 7 days of life, need for surfactant post-randomization, time to CPAP failure, duration of CPAP and complications of prematurity. An intention to treat analysis was done. One-hundred seventy neonates were randomized, 80 to J-CPAP and 90 to B-CPAP. CPAP failure rates within 72 h were similar in infants who received J-CPAP and in those who received B-CPAP (29 versus 21%; relative risks 1.4 (0.8 to 2.3), P=0.25). Mean (95% confidence intervals) time to CPAP failure was 59 h (54 to 64) in the Jet CPAP group in comparison with 65 h (62 to 68) in the Bubble CPAP group (log rank P=0.19). All other secondary outcomes were similar between the two groups. In preterm infants with respiratory distress starting within 6 h of life, CPAP failure rates were similar with Jet CPAP and Bubble CPAP.

    Nutritional guidelines involving the feeding of very low birth weight babies (VLBW) recommend addition of Human Milk Fortifiers to breast milk. Owing to financial constraints, it is a practice in low- and middle-income countries (LMIC) to add coconut oil to aid better weight gain. There are inadequate data on improvement of growth parameters with oral coconut oil supplementation of breast milk. In this randomized controlled trial, we measured growth parameters and body composition of 60 babies who received either breast milk with coconut oil or breast milk alone. Randomization was stratified according to intrauterine growth appropriate for gestational age (n = 30) and small for gestational age (n = 30). There was no difference in weight gain between the two groups. The weight gain velocity was 15 ± 3.6 and 14.4 ± 3.4 g/kg/day (p value = 0.49) in the breast milk alone and in the breast milk with coconut oil group, respectively. There was no difference in increase in head circumference and length. Triceps skinfold thickness (n = 56) was similar in both groups, but subscapular skinfold thickness was significantly more in the coconut oil group. Total body fat percentage did not differ between the groups (25.2 ± 4.3 vs. 25.5 ± 4.3%, p = 0.79). Oral supplementation of coconut oil along with breast milk did not increase growth parameters or result in change in body composition in very low birth weight (VLBW) babies.

Adult inpatients with a current manic episode fulfilling DSM-IV-TR diagnostic criteria for bipolar type I disorder were included. Patients were randomized to amisulpride (400–800 mg/day or haloperidol (5–15 mg/day for 3 months and all received valproate. The primary effectiveness criterion was the percentage of responders (defined by a decrease of ≥50% of the Y-MRS in patients completing the study. Safety was evaluated by adverse event reporting, determination of extrapyramidal function and clinical examination. Sixty-two patients were randomized to receive valproate-amisulpride, and 61 to receive valproate-haloperidol. At study end, responder rates were 72.6% in the amisulpride group and 65.5% in the haloperidol group. Remission rates were 83.9% and 89.7%, respectively. At study end, neither response rates nor remission rates differed significantly between groups. Treatment-emergent adverse events occurred significantly (p = 0.009 more frequently in the haloperidol group (86.4% than in the amisulpride group (66.1%. In conclusion, the valproate–amisulpride combination was as effective as the valproate – haloperidol combination in bipolar I patients, with a better safety profile.Keywords: amisulpride, valproate, haloperidol, clinical trial, mania, bipolar disorder

    Vacation can present a major problem to patients with rheumatoid arthritis (RA) treated with weekly subcutaneous biologics, including subcutaneous (SC) abatacept. Therefore, the replacement of four SC doses of abatacept by a single dose of intravenous (IV) abatacept may present an acceptable alternative to cover a 4-week interval needed for vacations. In the study presented, we analyzed the efficacy and safety of this intervention followed by a switch back to SC abatacept after 4 weeks. This open-label, prospective, single-arm, 24-week trial recruited patients with established RA in low disease activity (LDA) or in remission on treatment with SC abatacept for at least 3 months to receive a single dose of IV abatacept (baseline) followed by a break of 4 weeks and then continuation of weekly SC abatacept from day 28 on. Disease-modifying anti-rheumatic drug (DMARD)-inadequate or biologic-inadequate responders (or both) were included. The baseline characteristics of the 49 patients (per protocol) were typical for a cohort of RA patients with established disease (mean disease duration of 8.31 years) in LDA under treatment with synthetic DMARDs and a biologic. Two patients (one flare and one patient decision) dropped out of the study. The proportions of patients with disease activity score in 28 joints (DAS-28) of not more than 3.2 at day 28 were 93.9 % (95 % confidence interval (CI) 83.5-97.9) and 93.6 % (95 % CI 82.8-97.8) at the end of the study (day 168). The average DAS-28 values were 1.74 (standard deviation (SD) ± 0.72) at baseline, 2.03 (SD ± 1.03) at day 28, and 1.96 (SD ± 0.92) at the end of the study (day 168). Pre-exposure to IV abatacept and having failed methotrexate or anti-tumor necrosis factor (anti-TNF) did not influence the average DAS-28 or the proportion of patients maintaining LDA over time. The average health assessment questionnaire disability index (HAQ-DI) was stable throughout the study. Adverse events (AEs) occurred in

    Ischaemic heart disease (IHD) is one of the most common causes of death in the UK and treatment of patients with IHD costs the National Health System (NHS) billions of pounds each year. Allopurinol is a xanthine oxidase inhibitor used to prevent gout that also has several positive effects on the cardiovascular system. The ALL-HEART study aims to determine whether allopurinol improves cardiovascular outcomes in patients with IHD. The ALL-HEART study is a multicentre, controlled, prospective, randomised, open-label blinded end point (PROBE) trial of allopurinol (up to 600 mg daily) versus no treatment in a 1:1 ratio, added to usual care, in 5215 patients aged 60 years and over with IHD. Patients are followed up by electronic record linkage and annual questionnaires for an average of 4 years. The primary outcome is the composite of non-fatal myocardial infarction, non-fatal stroke or cardiovascular death. Secondary outcomes include all-cause mortality, quality of life and cost-effectiveness of allopurinol. The study will end when 631 adjudicated primary outcomes have occurred. The study is powered at 80% to detect a 20% reduction in the primary end point for the intervention. Patient recruitment to the ALL-HEART study started in February 2014. The study received ethical approval from the East of Scotland Research Ethics Service (EoSRES) REC 2 (13/ES/0104). The study is event-driven and results are expected after 2019. Results will be reported in peer-reviewed journals and at scientific meetings. Results will also be disseminated to guideline committees, NHS organisations and patient groups. 32017426, pre-results.

    Comparative bioavailability studies are conducted to establish the bioequivalence of generic formulation with that of branded reference formulation, providing confidence to clinicians to use these products interchangeably. This study was carried out to compare a locally manufactured formulation of flurbiprofen with that of a branded product. Twenty two healthy male adults received a single dose of flurbiprofen (100mg) either generic or branded product according to randomization scheme on each of 2 periods. Blood samples were collected and plasma flurbiprofen concentration was determined by a validated HPLC method. Pharmacokinetic parameters like AUC(0-t), AUC(0-oo), Cmax, Tmax, t½, Vd and clearance were determined. The 90% CI for the ratio of geometric means of test to reference product's pharmacokinetic variables was calculated. Pharmacokinetic parameters for two formulations were comparable. Ratio of means of AUC(0-24), AUC(0-oo) and Cmax for test to reference products and 90% CI for these ratios were within the acceptable range. The p-values calculated by TOST were much less than the specified value (p-0.05). ANOVA gave p-values which were more than the specified value (p-0.05) for sequence, subject, period and formulation. Test formulation of flurbiprofen (tablet Flurso) was found to meet the criteria for bioequivalence to branded product (tablet Ansaid) based on pharmacokinetic parameters.

    This study investigated the effectiveness of diaphragm biofeedback training (DBT) for patients with gastroesophageal reflux disease (GERD). A total of 40 patients with GERD treated at the Peking Union Medical College Hospital between September 2004 and July 2006 were randomized to receive DBT and rabeprazole proton pump inhibitor (PPI) or rabeprazole alone. The DBT + rabeprazole group received DBT during the 8-week initial treatment; the rabeprazole group did not. During the 6-month follow up, all patients took acid suppression according to their reflux symptoms, and the patients in the DBT + rabeprazole group were required to continue DBT. The primary outcome (used for power analysis) was the amount of acid suppression used at 6 months. Secondary outcomes were reflux symptoms, health-related quality of life (HRQL), and esophageal motility differences after the 8-week treatment compared with baseline. Acid suppression usage significantly decreased in the DBT + rabeprazole group compared with the rabeprazole group at 6 months (P reflux symptoms and GERD-HRQL were significantly improved in both groups (P gastroesophageal junction pressure (GEJP) significantly increased in the DBT + rabeprazole group (P reflux barrier, providing a non-pharmacological maintenance therapy and reducing medical costs for patients with GERD. © 2015 International Society for Diseases of the Esophagus.

    Fibromyalgia is a chronic musculoskeletal pain syndrome characterized by a broad spectrum of manifestations. Patients with fibromyalgia frequently suffer from manifestations similar to those experienced by patients with gluten-related disorders raising the possibility that some patients with fibromyalgia could suffer from underlying gluten sensitivity. This study aims to assess whether avoiding gluten among patients with fibromyalgia and gluten sensitivity is beneficial. Adult patients with fibromyalgia presenting gluten sensitivity symptoms are randomly allocated to receive gluten-free diet or hypocaloric diet for 24 weeks. The primary outcome measure is the mean change in the number of experienced gluten sensitivity symptoms. Secondary outcome measures include the mean changes in the body mass index, Revised Fibromyalgia Impact Questionnaire, Pittsburgh Sleep Quality Index, Brief Pain Inventory, Beck Depression Inventory-II, State-Trait Anxiety Inventory, Short-Form Health Survey and Patient Global Impression Scale of Severity. Other secondary outcome measures include the frequency of potential adverse events and the proportion of responders according to the Patient Global Impression Scale of Improvement. Previous studies assessing dietary interventions in fibromyalgia primarily evaluated their effects on the severity and impact of fibromyalgia symptoms and pain. The current study is the first to evaluate the effects of gluten-free diet on the gluten sensitivity symptoms experienced by patients with fibromyalgia. The results of this study will contribute to a better understanding of the potential role of gluten sensitivity in fibromyalgia. Copyright © 2014 Elsevier Inc. All rights reserved.

    Potential interactions between vaccines may compromise the immunogenicity and/or safety of individual vaccines so must be assessed before concomitant administration is recommended. In this study, the immunogenicity and safety of travel vaccines against Japanese encephalitis (JEV) and rabies (PCECV) administered together with or without a quadrivalent meningococcal glycoconjugate ACWY-CRM vaccine were evaluated (NCT01466387). Healthy adults aged 18 to ≤60 years were randomized to one of four vaccine regimens: JEV + PCECV + MenACWY-CRM, JEV + PCECV, PCECV or MenACWY-CRM. Immunogenicity at baseline and 28 days post-complete vaccination was assessed by serum bactericidal assay using human complement or neutralization tests. Adverse events (AEs) were collected throughout the study period. JEV + PCECV + MenACWY-CRM was non-inferior to JEV + PCECV. Post-vaccination seroprotective neutralizing titers or concentrations were achieved in 98-99% (JE) and 100% (rabies) of subjects across the vaccine groups. Antibody responses to vaccine meningococcal serogroups were in the same range for MenACWY-CRM and JEV + PCECV + MenACWY-CRM. Rates of reporting of AEs were similar for JEV + PCECV and JEV + PCECV + MenACWY-CRM. MenACWY-CRM was administered with an inactivated adjuvanted JE and a purified chick embryo cell-culture rabies vaccine without compromising immunogenicity or safety of the individual vaccines. These data provide evidence that MenACWY-CRM could be effectively incorporated into travel vaccination programs. NCT01466387. Copyright © 2014 Elsevier Ltd. All rights reserved.

    This study evaluated the safety/tolerability and effectiveness of aripiprazole titrated-dose versus fixed-dose switching strategies from risperidone in patients with schizophrenia experiencing insufficient efficacy and/or safety/tolerability issues. Patients were randomized to an aripiprazole titrated-dose (starting dose 5 mg/day) or fixed-dose (dose 15 mg/day) switching strategy with risperidone down-tapering. Primary endpoint was rate of discontinuation due to adverse events (AEs) during the 12-week study. Secondary endpoints included positive and negative syndrome scale (PANSS), clinical global impressions - improvement of illness scale (CGI-I), preference of medication (POM), subjective well-being under neuroleptics (SWN-K) and GEOPTE (Grupo Español para la Optimización del Tratamiento de la Esquizofrenia) scales. Rates of discontinuations due to AEs were similar between titrated-dose and fixed-dose strategies (3.5% vs. 5.0%; p=0.448). Improvements in mean PANSS total scores were similar between aripiprazole titrated-dose and fixed-dose strategies (-14.8 vs. -17.2; LOCF), as were mean CGI-I scores (2.9 vs. 2.8; p=0.425; LOCF) and SWN-K scores (+8.6 vs.+10.3; OC,+7.8 vs.+9.8; LOCF). Switching can be effectively and safely achieved through a titrated-dose or fixed-dose switching strategy for aripiprazole, with down-titration of risperidone.

    Full Text Available Introduction. Nicotinic acid (NA and statins have been associated with reductions in blood pressure (BP. Patients and Methods. We recruited 68 normotensive and hypertensive dyslipidemic patients who were treated with a conventional statin dose and had not achieved lipid targets. Patients were randomized to switch to high-dose rosuvastatin (40 mg/day or to add-on current statin treatment with extended release (ER NA/laropiprant (1000/20 mg/day for the first 4 weeks followed by 2000/40 mg/day for the next 8 weeks for 3 months. Results. Switching to rosuvastatin 40 mg/day was not associated with significant BP alterations. In contrast, the addition of ER-NA/laropiprant to current statin treatment resulted in a 7% reduction of systolic BP (from 134±12 to 125±10 mmHg, <.001 versus baseline and =.01 versus rosuvastatin group and a 5% reduction of diastolic BP (from 81±9 to 77±6 mmHg, =.009 versus baseline and =.01 versus rosuvastatin group. These reductions were significant only in the subgroup of hypertensives and were independent of the hypolipidemic effects of ER-NA/laropiprant. Conclusions. Contrary to the switch to high-dose rosuvastatin, the addition of ER-NA/laropiprant to statin treatment was associated with significant reductions in both systolic and diastolic BP.

    Guidelines recommendations regarding anticoagulant therapy after percutaneous coronary intervention (PCI) among patients with atrial fibrillation (AF) rely on retrospective, nonrandomized observational data. Currently, patients are treated with triple-therapy (dual antiplatelet therapy [DAPT] + oral anticoagulation therapy), but neither the duration of DAPT nor the level of anticoagulation has been studied in a randomized fashion. Recent studies also suggest dual pathway therapy with clopidogrel plus oral anticoagulation therapy may be superior, and other studies suggest that novel oral anticoagulants such as rivaroxaban may further improve patient outcomes. PIONEER AF-PCI (ClinicalTrials.gov NCT01830543) is an exploratory, open-label, randomized, multicenter clinical study assessing the safety of 2 rivaroxaban treatment strategies and 1 vitamin K antagonist (VKA) treatment strategy in subjects who have paroxysmal, persistent, or permanent nonvalvular AF and have undergone PCI with stent placement. Approximately 2,100 subjects will be randomized in a 1:1:1 ratio to receive either rivaroxaban 15 mg once daily plus clopidogrel 75 mg daily for 12 months (a WOEST trial-like strategy), or rivaroxaban 2.5 mg twice daily (with stratification to a prespecified duration of DAPT 1, 6, or 12 months, an ATLAS trial-like strategy), or dose-adjusted VKA once daily (with stratification to a prespecified duration of DAPT 1, 6, or 12 months, traditional triple therapy). All patients will be followed up for 12 months for the primary composite end point of Thrombolysis in Myocardial Infarction major bleeding, bleeding requiring medical attention, and minor bleeding (collectively, clinically significant bleeding). The PIONEER AF-PCI study is the first randomized comparison of VKA vs novel oral anticoagulant therapy in patients with NVAF receiving antiplatelet therapy after PCI to assess the relative risks of bleeding complications.

    Despite the rapid adoption of the World Health Organization's 2013 guidelines, children continue to be infected with HIV perinatally because of sub-optimal adherence to the continuum of HIV care in maternal and child health (MCH) clinics. To achieve the UNAIDS goal of eliminating mother-to-child HIV transmission, multiple, adaptive interventions need to be implemented to improve adherence to the HIV continuum. The aim of this open label, parallel, group randomized trial is to evaluate the effectiveness of Continuous Quality Improvement (CQI) interventions implemented at facility and health district levels to improve retention in care and virological suppression through 24 months postpartum among pregnant and breastfeeding women receiving ART in MCH clinics in Kinshasa, Democratic Republic of Congo. Prior to randomization, the current monitoring and evaluation system will be strengthened to enable collection of high quality individual patient-level data necessary for timely indicators production and program outcomes monitoring to inform CQI interventions. Following randomization, in health districts randomized to CQI, quality improvement (QI) teams will be established at the district level and at MCH clinics level. For 18 months, QI teams will be brought together quarterly to identify key bottlenecks in the care delivery system using data from the monitoring system, develop an action plan to address those bottlenecks, and implement the action plan at the level of their district or clinics. If proven to be effective, CQI as designed here, could be scaled up rapidly in resource-scarce settings to accelerate progress towards the goal of an AIDS free generation. The protocol was retrospectively registered on February 7, 2017. ClinicalTrials.gov Identifier: NCT03048669 .

The purpose of this study was to elucidate the difference in efficacy of LAMA and LABA alone and the combination thereof for DLH. Subjects and methods: Thirty stable patients were enrolled and randomly divided into two groups following baseline measurements. One group was treated with 5 µg tiotropium (Respimat inhaler for 4 weeks following a 4-week treatment with 150 µg indacaterol, while the other group was treated with indacaterol for 4 weeks following a 4-week treatment with tiotropium. For both groups, these treatments were followed by a combination of the two drugs for 4 weeks. Pulmonary function tests, including DLH evaluated by metronome-paced incremental hyperventilation and exercise tolerance evaluated by the shuttle-walk test, were performed at the end of each treatment period. Results: In total, 23 patients completed this study. Both tiotropium and indacaterol alone significantly increased forced expiratory volume in 1 second, exercise tolerance, and improved health status. Tiotropium significantly improved DLH, but indacaterol did not. The combination therapy resulted in further improvements in lung function and exercise tolerance, but not in DLH. Conclusion: The efficacy of tiotropium in inhibiting DLH following metronome-paced incremental hyperventilation may be superior to that of 150 µg indacaterol, although the effects on airflow obstruction were the same, and the combination therapy showed further improvement in airflow

The reduced glycerin VF (RGVF gel was used in the MTN-007 Phase 1 rectal microbicide trial and is currently being evaluated in the MTN-017 Phase 2 rectal microbicide trial. A third rectal specific formulation (RF gel was also evaluated in the CHARM-01 study.Participants received 4 mL of the three TFV gels in a blinded, crossover design: seven daily doses of RGVF, seven daily doses of RF, and six daily doses of placebo followed by one dose of VF, in a randomized sequence. Safety, acceptability, compartmental PK, and explant PD were monitored throughout the trial.All three gels were found to be safe and acceptable. RF and RGVF PK were not significantly different. Median mucosal mononuclear cell (MMC TFV-DP trended toward higher values for RF compared to RGVF (1136 and 320 fmol/106 cells respectively. Use of each gel in vivo was associated with significant inhibition of ex vivo colorectal tissue HIV infection. There was also a significant negative correlation between the tissue levels of TFV, tissue TFV-DP, MMC TFV-DP, rectal fluid TFV, and explant HIV-1 infection.All three formulations were found to be safe and acceptable. However, the safety profile of the VF gel was only based on exposure to one dose whereas participants received seven doses of the RGVF and RF gels. There was a trend towards higher tissue MMC levels of TFV-DP associated with use of the RF gel. Use of all gels was associated with significant inhibition of ex vivo tissue HIV infection.ClinicalTrials.gov NCT01575405.

    The oral administration of the gum resin extracts of Indian frankincense (Boswellia serrata Roxb. ex Colebr) results in very low plasma concentrations of boswellic acids (BAs), being far below the pharmacologically active concentrations required in vitro for anti-inflammatory activity. For that reason the use of Indian frankincense in clinical practice and pharmaceutical development has substantially lagged behind. Recently the application of new formulation technologies resulted in a formulation of frankincense extract with lecithin, which revealed improved absorption and tissue penetration of BAs in a rodent study, leading for the first time to plasma concentrations of BAs in the range of their anti-inflammatory activity. In order to verify these encouraging results in humans, the absorption of a standardized Boswellia serrata extract (BE) and its lecithin formulation (CSP) was comparatively investigated in healthy volunteers. According to a randomized cross-over design with two treatments, two sequences and two periods, 12 volunteers alternatively received the lecithin-formulated Boswellia extract (CSP) or the non-formulated Boswellia extract (BE) at a dosage of 2×250mg capsules. The plasma concentrations of the six major BAs (KBA, AKBA, βBA, αBA, AβBA, AαBA) were determined using LC/MS. With the exception of KBA, a significantly higher (both in terms of weight-to-weight and molar comparison) and quicker absorption of BAs from the lecithin formulation was observed, leading to C max in the range required for the interaction with their molecular targets. These findings pave the way to further studies evaluating the clinical potential of BAs, and verify the beneficial effect of lecithin formulation to improve the absorption of poorly soluble phytochemicals.

    The efficacy and safety of sirolimus (SRL) plus tacrolimus (TAC) versus SRL plus cyclosporine (CsA) were compared in high-risk renal allograft recipients. Evaluable patients (448) were randomly assigned (1:1) before transplant to receive SRL+TAC or SRL+CsA with corticosteroids. Eligible patients were black and/or repeat transplant recipients, and/or those with high titer of panel-reactive antibodies. Demographics were similar between groups. Both treatments demonstrated equivalent efficacy of the composite endpoint at 12 months with efficacy failure rates of 21.9% vs. 23.2% (SRL+TAC vs. SRL+CsA, respectively, 95% CI -10.0 to 7.1, P=0.737). Biopsy-confirmed acute rejection rate (13.8% vs. 17.4%) and graft survival rate (89.7% vs. 90.2%) were similar (SRL+TAC vs. SRL+CsA, respectively). In evaluable patients (received at least 1 dose of study drug), renal function (calculated Nankivell glomerular filtration rate) was not superior in SRL+TAC versus SRL+CsA (54.5 vs. 52.6 mL/min, P=0.466); however, in on-therapy patients, glomerular filtration rate was significantly higher in SRL+TAC at most time points. At 12 months, there were no significant differences in rates of death, discontinuation because of adverse events, hypercholesterolemia, hyperlipemia, or proteinuria. Diarrhea and herpes simplex infections occurred significantly more often in SRL+TAC patients. Hypertension, cardiomegaly, increased creatinine, overdose (primarily calcineurin inhibitor toxicity), acne, urinary tract disorders, lymphocele, and ovarian cysts occurred significantly more often in SRL+CsA patients. This study demonstrated that SRL-based therapy was efficacious in high-risk renal allograft recipients in the first year after transplant, providing equivalent efficacy with CsA or TAC, similar graft survival, low biopsy-confirmed acute rejection rates, excellent renal function, and an acceptable safety profile.

    Eating habits may influence the life span and the quality of ageing process by modulating inflammation. The RISTOMED project was developed to provide a personalized and balanced diet, enriched with or without nutraceutical compounds, to decrease and prevent inflammageing, oxidative stress and gut microbiota alteration in healthy elderly people. This paper focused on the effect on inflammation and metabolism markers after 56 days of RISTOMED diet alone or supplementation with three nutraceutical compounds. A cohort of 125 healthy elderly subjects was recruited and randomized into 4 arms (Arm A, RISTOMED diet; Arm B, RISTOMED diet plus VSL#3 probiotic blend; Arm C, RISTOMED diet plus AISA d-Limonene; Arm D, RISTOMED diet plus Argan oil). Inflammatory and metabolism parameters as well as the ratio between Clostridium cluster IV and Bifidobacteria (CL/B) were collected before and after 56 days of dietary intervention, and their evolution compared among the arms. Moreover, participants were subdivided according to their baseline inflammatory parameters (erythrocytes sedimentation rate (ESR), C-Reactive Protein, fibrinogen, Tumor Necrosis Factor-alfa (TNF-α), and Interleukin 6) in two clusters with low or medium-high level of inflammation. The evolution of the measured parameters was then examined separately in each cluster. Overall, RISTOMED diet alone or with each nutraceutical supplementation significantly decreased ESR. RISTOMED diet supplemented with d-Limonene resulted in a decrease in fibrinogen, glucose, insulin levels and HOMA-IR. The most beneficial effects were observed in subjects with a medium-high inflammatory status who received RISTOMED diet with AISA d-Limonene supplementation. Moreover, RISTOMED diet associated with VSL#3 probiotic blend induced a decrease in the CL/B ratio. Overall, this study emphasizes the beneficial anti-inflammageing effect of RISTOMED diet supplemented with nutraceuticals to control the inflammatory status of elderly

    Neisseria meningitidis is associated with high mortality and morbidity in infants and children worldwide. This phase 3 study (NCT02173704) evaluated safety and immunogenicity of a 4-component serogroup B recombinant meningococcal vaccine (4CMenB) co-administered with routine vaccines in Taiwanese infants. In total, 225 healthy infants were randomized (2 : 1 ) to receive 4CMenB and routine vaccines (4CMenB+Routine) or routine vaccines only (Routine group) at 2, 4, 6 and 12 months of age. Routine vaccines were diphtheria-tetanus-acellular pertussis-inactivated poliovirus-Haemophilus influenzae type b, 13-valent pneumococcal, hepatitis B, measles-mumps-rubella and varicella vaccines. Immune responses to 4CMenB components (factor H binding protein [fHbp], Neisserial adhesin A [NadA], porin A [PorA] and Neisseria heparin-binding antigen [NHBA]) were evaluated at 1 month post-primary and post-booster vaccination, using human serum bactericidal assay (hSBA). Reactogenicity and safety were also assessed. A sufficient immune response was demonstrated for fHbp, NadA and PorA, at 1 month post-primary and booster vaccination. In the 4CMenB+Routine group, hSBA titers ≥5 were observed in all infants for fHbp and NadA, in 79% and 59% of infants for PorA and NHBA, respectively, at 1 month post-primary vaccination and in 92-99% of infants for all antigens, at 1 month post-booster vaccination. In the 4CMenB+Routine group, hSBA geometric mean titers for all antigens increased post-primary (8.41-963) and post-booster vaccination (17-2315) compared to baseline (1.01-1.36). Immunogenicity of 4CMenB was not impacted by co-administration with routine pediatric vaccines in infants. Reactogenicity was slightly higher in the 4CMenB+Routine group compared with Routine group, but no safety concerns were identified.

    Because of practical problems and ethical concerns, few studies of the pharmacokinetics (PK) of acetaminophen (ACET) in infants have been published. The goal of this study was to compare the PK of an ACET rectal suppository with a commercially available ACET elixir to complete a regulatory obligation to market the suppository. This study was not submitted previously because of numerous obstacles related to both the investigators and the commercial entities associated with the tested product. Thirty infants (age 3-36 months) prescribed ACET for either fever, pain, or postimmunization prophylaxis of fever and discomfort were randomized to receive a single 10- to 15-mg/kg ACET dose either as the rectal suppository or oral elixir. Blood was collected at selected times for up to 8 hours after administration. ACET concentrations were measured by using a validated HPLC method, and PK behavior and bioavailability were compared for the 2 preparations. All 30 infants enrolled were prescribed ACET for postimmunization prophylaxis. PK samples were available in 27 of the 30 enrolled infants. Subject enrollment (completed in January 1995) was rapid (8.3 months) and drawn entirely from a vaccinated infant clinic population. There were no statistically significant differences between the subjects (elixir, n = 12; suppository, n = 15) in either mean (SD) age (10.0 [6.3] vs 12.4 [8.1] months), weight (8.6 [2.3] vs 9.4 [2.4] kg), sex (7 of 12 males vs 7 of 15 males), or racial distribution (5 white, 5 black, and 2 biracial vs 4 white and 11 black) between the 2 dosing groups (oral vs rectal, respectively). The oral and rectal preparations produced similar, rapid peak concentrations (T(max), 1.16 vs 1.17 hours; P = 0.98) and elimination t(½) (1.84 vs 2.10 hours; P = 0.14), respectively. No statistically significant differences were found between either C(max) (7.65 vs 5.68 μg/mL) or total drug exposure (AUC(0-∞), 23.36 vs 20.45 μg-h/mL) for the oral versus rectal preparations

    Glycemic control in participants with insulin-treated diabetes remains challenging. We assessed safety and efficacy of new flash glucose-sensing technology to replace self-monitoring of blood glucose (SMBG). This open-label randomized controlled study (ClinicalTrials.gov, NCT02082184) enrolled adults with type 2 diabetes on intensive insulin therapy from 26 European diabetes centers. Following 2 weeks of blinded sensor wear, 2:1 (intervention/control) randomization (centrally, using biased-coin minimization dependant on study center and insulin administration) was to control (SMBG) or intervention (glucose-sensing technology). Participants and investigators were not masked to group allocation. Primary outcome was difference in HbA1c at 6 months in the full analysis set. Prespecified secondary outcomes included time in hypoglycemia, effect of age, and patient satisfaction. Participants (n = 224) were randomized (149 intervention, 75 controls). At 6 months, there was no difference in the change in HbA1c between intervention and controls: -3.1 ± 0.75 mmol/mol, [-0.29 ± 0.07% (mean ± SE)] and -3.4 ± 1.04 mmol/mol (-0.31 ± 0.09%) respectively; p = 0.8222. A difference was detected in participants aged glucose-sensing technology use in type 2 diabetes with intensive insulin therapy results in no difference in HbA1c change and reduced hypoglycemia, thus offering a safe, effective replacement for SMBG.

    It is unclear whether simultaneous administration of a 23-valent pneumococcal polysaccharide vaccine (PPSV23) and a quadrivalent influenza vaccine (QIV) produces immunogenicity in older individuals. This study tested the hypothesis that the pneumococcal antibody response elicited by simultaneous administration of PPSV23 and QIV in older individuals is not inferior to that elicited by sequential administration of PPSV23 and QIV. We performed a single-center, randomized, open-label, non-inferiority trial comprising 162 adults aged ≥65 years randomly assigned to either the simultaneous (simultaneous injections of PPSV23 and QIV) or sequential (control; PPSV23 injected 2 weeks after QIV vaccination) groups. Pneumococcal immunoglobulin G (IgG) titers of serotypes 23F, 3, 4, 6B, 14, and 19A were assessed. The primary endpoint was the serotype 23F response rate (a ≥2-fold increase in IgG concentrations 4-6 weeks after PPSV23 vaccination). With the non-inferiority margin set at 20% fewer patients, the response rate of serotype 23F in the simultaneous group (77.8%) was not inferior to that of the sequential group (77.6%; difference, 0.1%; 90% confidence interval, -10.8% to 11.1%). None of the pneumococcal IgG serotype titers were significantly different between the groups 4-6 weeks after vaccination. Simultaneous administration did not show a significant decrease in seroprotection odds ratios for H1N1, H3N2, or B/Phuket influenza strains other than B/Texas. Additionally, simultaneous administration did not increase adverse reactions. Hence, simultaneous administration of PPSV23 and QIV shows an acceptable immunogenicity that is comparable to sequential administration without an increase in adverse reactions. (This study was registered with ClinicalTrials.gov [NCT02592486]).

    The proprietary formulation of fluoxetine hydrochloride is an antidepressant of the selective serotonin reuptake inhibitor class. Pharmacokinetic studies investigating the bioequivalence of generic and branded formulations are needed to market generic fluoxetine in China. The aim of this study was to compare the bioavailability and tolerability of the proposed generic formulation with the established reference formulation of fluoxetine hydrochloride 20 mg in a fasting, healthy Chinese male population. This 10-week, open-label, randomized-sequence, single-dose, 2-period crossover study was conducted in healthy native Han Chinese male volunteers. Eligible subjects were randomly assigned in a 1:1 ratio to receive a single 20-mg dose of the test or reference formulation, followed by a 35-day washout period and administration of the alternate formulation. Doses were administered after a 12-hour overnight fast. For analysis of pharmacokinetic properties (including C(max), T(max), AUC(0-t), AUC(0-∞), and t(½)), blood samples were obtained over a 672-hour period after dosing. Plasma concentrations of fluoxetine and its active metabolite, norfluoxetine, were analyzed using a validated LC-MS/MS method. The formulations were to be considered bioequivalent if the ln-transformed ratios (test/ reference) of C(max) and AUC were within the predetermined bioequivalence range of 80% to 125%, as established by the US Food and Drug Administration, and if the P values were fasting, healthy Chinese male volunteers. Both formulations appeared to be well tolerated. Copyright © 2010 Excerpta Medica Inc. All rights reserved.

    Tofacitinib is an oral Janus kinase inhibitor being investigated for psoriasis. We sought to report longer-term tofacitinib efficacy and safety in patients with moderate to severe psoriasis. Data from 2 identical phase-III studies, Oral-treatment Psoriasis Trial Pivotal 1 and 2, were pooled with data from these patients in an ongoing open-label long-term extension study. Patients (n = 1861) were randomized 2:2:1 to tofacitinib 5 mg, 10 mg, or placebo twice daily (BID). At week 16, placebo patients were rerandomized to tofacitinib. Pivotal study participants could enroll into the long-term extension where they received tofacitinib at 10 mg BID for 3 months, after which dosing could be 5 or 10 mg BID. At week 28, the proportions of patients randomized to tofacitinib 5 and 10 mg BID achieving 75% or greater reduction in Psoriasis Area and Severity Index score from baseline were 55.6% and 68.8%, and achieving Physician Global Assessment of clear or almost clear were 54.7% and 65.9%. Efficacy was maintained in most patients through 24 months. Serious adverse events and discontinuations because of adverse events were reported in less than 11% of patients over 33 months of tofacitinib exposure. There was no dose comparison beyond week 52. Oral tofacitinib demonstrated sustained efficacy in patients with psoriasis through 2 years, with 10 mg BID providing greater efficacy than 5 mg BID. No unexpected safety findings were observed.

    Nocturnal blood pressure (BP) appears to be a better predictor of cardiovascular outcome than daytime BP. The BP lowering effects of most antihypertensive therapies are often greater in the first 12 h compared to the next 12 h. The Treatment In Morning versus Evening (TIME) study aims to establish whether evening dosing is more cardioprotective than morning dosing. The TIME study uses the prospective, randomised, open-label, blinded end-point (PROBE) design. TIME recruits participants by advertising in the community, from primary and secondary care, and from databases of consented patients in the UK. Participants must be aged over 18 years, prescribed at least one antihypertensive drug taken once a day, and have a valid email address. After the participants have self-enrolled and consented on the secure TIME website (http://www.timestudy.co.uk) they are randomised to take their antihypertensive medication in the morning or the evening. Participant follow-ups are conducted after 1 month and then every 3 months by automated email. The trial is expected to run for 5 years, randomising 10,269 participants, with average participant follow-up being 4 years. The primary end point is hospitalisation for the composite end point of non-fatal myocardial infarction (MI), non-fatal stroke (cerebrovascular accident; CVA) or any vascular death determined by record-linkage. Secondary end points are: each component of the primary end point, hospitalisation for non-fatal stroke, hospitalisation for non-fatal MI, cardiovascular death, all-cause mortality, hospitalisation or death from congestive heart failure. The primary outcome will be a comparison of time to first event comparing morning versus evening dosing using an intention-to-treat analysis. The sample size is calculated for a two-sided test to detect 20% superiority at 80% power. TIME has ethical approval in the UK, and results will be published in a peer-reviewed journal.

    Postoperative ileus (POI) is a frequent complication after abdominal surgery (AS). Until today, neither a prophylaxis nor an evidence-based therapy exists. This originates from the absence of objective parameters evaluating the severity and duration of POI resulting in clinical trials of modest quality. The SmartPill(®), a capsule which frequently measures pH value, temperature and intraluminal pressure after swallowing, offers an elegant option for analysing gastrointestinal (GI) transit times and smooth muscle activity in vivo. As the use in patients in the first months after AS is not covered by the marketing authorisation, we aim to investigate the safety and feasibility of the SmartPill(®) immediately after surgery. Additionally, we analyse the influence of prokinetics and laxatives as well as standardised physiotherapy on postoperative bowel contractility, as scientific evidence of its effects is still lacking. The PIDuSA study is a prospective, single-centre, two-arm, open-label trial. The SmartPill(®) will be applied to 55 patients undergoing AS having a high risk for POI and 10 patients undergoing extra-abdominal surgery rarely developing POI. The primary objective is the safety of the SmartPill(®) in patients after surgery on the basis of adverse device effects/serious adverse device effects (ADE/SADE). The sample size suggests that events with a probability of 3% could be seen with a certainty of 80% for at least once in the sample. Secondary objective is the analysis of postoperative intestinal activity in the GI tract in both groups. Furthermore, clinical signs of bowel motility disorders will be correlated to the data measured by the SmartPill(®) to evaluate its significance as an objective parameter for assessing POI severity. Additionally, effects of prokinetics, laxatives and physiotherapy on postoperative peristaltic activity recorded by the SmartPill(®) will be analysed. The protocol was approved by the federal authority (94

    Nonsteroidal anti-inflammatory drugs (NSAIDs) can induce renal complications in patients taking loop diuretics. This study investigated the pharmacokinetic/pharmacodynamic effects and safety profile of orally administered diclofenac sodium, ibuprofen and diclofenac epolamine topical patch (DETP) on furosemide in healthy adult subjects. This open-label, randomized, 5-way crossover study was conducted in 40 subjects (aged 19 - 45 y). Diclofenac (75 mg taken orally twice daily), DETP (1.3% applied topically twice daily), or ibuprofen (800 mg taken orally thrice daily) was administered for 3 consecutive days, followed by co-administration with furosemide (given intravenously as 20 mg/2 min). Plasma furosemide and NSAID concentrations, urine furosemide, sodium and potassium concentrations and urine output were determined throughout the 24 h period following furosemide administration. Orally administered ibuprofen significantly increased furosemide AUC(0-t) (37%) and AUC(0-inf) (36%) and decreased total body CL (27%), R(max) (19%) and CLR (23%) geometric mean ratios compared with furosemide control. Oral and topical diclofenac had no pharmacokinetic effects on furosemide. Ibuprofen increased sodium excretion (Ae(0-24), 16%) and decreased sodium R(max) (15%), and oral diclofenac decreased urine output (Vu(0-24), 15%). DETP had no effect on furosemide pharmacodynamics; total systemic exposure to diclofenac during DETP treatment was diclofenac. Treatments were generally safe, with 25 subjects reporting a total of 112 adverse events. Pharmacodynamic effects were seen with oral diclofenac (urine output) and ibuprofen (urine sodium excretion). Furosemide also affected plasma and urine pharmacokinetic profiles. Pharmacologic effects of DETP on furosemide were not observed under these conditions. Additional research is warranted to delineate the potential interactions of other NSAIDs with furosemide and other loop diuretics.

    Artemisinin combination therapies are considered the mainstay of malaria treatment, but pediatric-friendly formulations for the treatment of infants are scarce. We sought to evaluate the efficacy and safety of a new dispersible-tablet formulation of dihydroartemisinin/piperaquine phosphate (DHA/PQP) in comparison to the marketed tablet (Eurartesim) in the treatment of infants with uncomplicated Plasmodium falciparum malaria. Reported here are the results of a large phase II, randomized, open-label, multicenter trial conducted in African infants (6 to 12 months of age) from Mozambique, Burkina Faso, The Gambia, the Democratic Republic of the Congo, and Tanzania. Primary efficacy endpoint was the PCR-corrected adequate clinical and parasitological response (ACPR) at day 28. Analysis was performed for the intention-to-treat (ITT) and per-protocol (PP) populations. A total of 201 patients received the dispersible-tablet formulation, and 99 received the conventional one administered as crushed tablets. At day 28, the PCR-corrected ACPRs were 86.9% (ITT) and 98.3% (PP) in the dispersible-tablet group and 84.9% (ITT) and 100% (PP) in the crushed-tablet group. At day 42, these values were 85.9% (ITT) and 96.5% (PP) in the dispersible-tablet group and 82.8% (ITT) and 96.4% (PP) in the crushed-tablet group. The comparison between survival curves for time to new infections showed no statistically significant differences ( P = 0.409). The safety and tolerability profile for the two groups was similar in terms of type and frequency of adverse events and was consistent with that expected in African infants with malaria. A standard 3-day treatment with the new dispersible DHA/PQP formulation is as efficacious as the currently used tablet in African infants and has a comparable safety profile.

    Until now there has been no study that directly compares the effect of lansoprazole and pantoprazole administered intravenously on intragastric acidity. The aim of this study is to compare the effect of lansoprazole (30 mg) and pantoprazole (40 mg) administered intravenously on gastric acidity. Helicobacter pylori-negative healthy volunteers were recruited in this open-label, randomized, two-way crossover, single centre study. Lansoprazole at 30 mg or pantoprazole at 40 mg was intravenously administered twice daily for 5 consecutive days with at least a 14-day washout interval. Twenty-four-hour intragastric pH was continuously monitored on days 1 and 5 of each dosing period. Twenty-five volunteers completed the 2 dosing periods. The mean intragastric pH values were higher in subjects treated with lansoprazole than those with pantoprazole on both day 1 (6.41 ± 0.14 vs. 5.49 ± 0.13, P=0.0003) and day 5 (7.09 ± 0.07 vs. 6.64 ± 0.07, P=0.0002). Significantly higher percentages of time with intragastric pH >4 and pH >6 were found in the subjects treated with lansoprazole than those with pantoprazole on day 1 (pH >4, 87.12 ± 4.55% vs. 62.28 ± 4.15%, P=0.0012; pH >6, 62.12 ± 4.12% vs. 47.25 ± 3.76%, P=0.0216) and pH >6 on day 5 (76.79 ± 3.77% vs. 58.20 ± 3.77%, P=0.0025). Intravenous lansoprazole produces a longer and more potent inhibitory effect on intragastric acidity than does intravenous pantoprazole.

    This phase III, non-randomized, open-label, multi-center study (NCT01827839) evaluated the immunogenicity and safety of an adjuvanted recombinant subunit herpes zoster (HZ) vaccine (HZ/su) in adults aged ≥ 50 y with prior physician-documented history of HZ. Participants (stratified by age: 50-59, 60-69 and ≥ 70 y) received 2 doses of HZ/su 2 months apart and were followed-up for another 12 months. Anti-glycoprotein E (gE) antibodies were measured by enzyme-linked immunosorbent assay before vaccination and 1 month after the second dose (Month 3). Solicited local and general adverse events (AEs) were recorded for 7 d and unsolicited AEs for 30 d after each vaccination. Serious AEs were recorded until study end. The primary immunogenicity objective was met if the lower limit of the 95% confidence interval (CI) of the vaccine response rate (VRR), defined as a 4-fold increase in anti-gE over baseline, at Month 3 was ≥ 60%. 96 participants (32/age group) were enrolled. The primary immunogenicity objective was met, as the VRR at Month 3 was 90.2% (95% CI: 81.7-95.7). Geometric mean anti-gE antibody concentrations at Month 3 were similar across age groups. 77.9% and 71.6% of participants reported local and general solicited AEs, respectively. The most frequent solicited AEs were pain at injection site, fatigue, headache, myalgia and shivering. The HZ/su vaccine was immunogenic in adults aged ≥ 50 y with a physician-documented history of HZ, and no safety concerns were identified.

    Studies evaluating the effect of education on treatment success with phosphodiesterase type 5 (PDE5) inhibitor therapy in men with erectile dysfunction (ED) are limited. Additional education of the primary care physician (PCP) and the patient are thought to optimize the treatment of ED. To assess the impact of education of the PCP or of the patient in the treatment of ED with vardenafil relative to usual care. In this 12-week, open-label, multicenter, factorial-designed, cluster-randomized Canadian study, 1,029 patients with ED were enrolled into four different education groups: usual care, patient education, PCP education, and both PCP and patient education. All groups started on vardenafil 10 mg, with the option to titrate at weeks 4 and 8. The primary efficacy measure was the difference at week 4 last observation carried forward (LOCF) in the overall improvement in erectile function (EF) as measured by the Global Assessment Question (GAQ), while on background vardenafil, between those receiving education vs. those who did not. Other secondary assessments included responses to diary questions regarding penetration (sexual encounter profile, SEP2) and erection maintenance (SEP3), and to questionnaires regarding treatment satisfaction (Erectile Dysfunction Inventory of Treatment Satisfaction [EDITS]). A total of 956 patients were included in the intent-to-treat population. Mean baseline International Index of Erectile Function-EF domain score was 13. GAQ response rates at week 4 LOCF were high (>80%) for all groups, regardless of the education given. Mean per patient SEP2 and SEP3 rates at week 12 LOCF were 86-89% and 79-83%, respectively. In an exploratory analysis, a positive relationship between GAQ responses and EDITS scores was observed (P satisfaction regardless of the education given. The benefits of education for PCP and patients in Canada were possibly masked by a ceiling effect in this study population.

    Venous thromboembolic events (VTE) are serious complications in children and for which the standard of care, unfractionated heparin followed by oral anticoagulation (UFH/OA), is problematic. The objective of REVIVE was to compare the efficacy and safety of a low molecular weight heparin (reviparin-sodium) to UFH/OA for the treatment of VTE in children. This multicenter, open-label study, with blinded central outcome adjudication, randomized patients with objectively confirmed VTE to receive either reviparin-sodium or UFH/OA. Dose adjustments were made using nomograms. The efficacy outcome was based on recurrent VTE and death due to VTE during the 3-month treatment period. The safety outcomes were major bleeding, minor bleeding and death. Due to slow patient accrual, REVIVE was closed prematurely. At 3 months, with reviparin-sodium, 2/36 patients (5.6%) had recurrent VTE or death compared to 4/40 patients (10.0%) receiving UFH/OA (odds ratio=0.53; 95% CI=(0.05, 4.00); Fisher's exact test: 2P=0.677). There were 7 major bleeds, 2/36 (5.6%) in the reviparin-sodium group and 5/40 (12.5%) in UFH/OA group (odds ratio=0.41; 95% confidence interval 0.04, 2.76); Fisher's exact test: P=0.435). There were 5 deaths during the study period, 1 (2.8%) in the reviparin-sodium group and 4 (10.0%) in the UFH/OA group. All five deaths were unrelated to VTE but one was due to an intracranial hemorrhage in the UFH/OA group. Although limited by small sample size, REVIVE provides valuable information on the incidence of recurrent VTE, major bleeding and problematic issues associated with therapy of VTE in children.

    An open-label, randomized, multicenter study was conducted to evaluate the safety and efficacy of long-term use of 2.5% and 5% benzoyl peroxide (BPO) gels administrated once daily for 52 weeks to Japanese patients with acne vulgaris. The efficacy of the study drugs was evaluated by counting inflammatory lesions and non-inflammatory lesions. Safety was evaluated based on adverse events, local skin tolerability scores and laboratory test values. In total, 458 subjects were included in the efficacy and safety analyses. The total lesion count, the efficacy end-point, was similarly changed both in the 2.5% and 5% BPO groups over the course of the study. The median rates of reduction from baseline to week 12 were approximately 65%. Thereafter, the counts were maintained at a reduced level without increasing until week 52. The median rates at week 52 were approximately 80%. Similar trends were observed for inflammatory and non-inflammatory lesion counts. Bacteriological evaluation indicated similar distribution of the minimum inhibitory concentration of each of the antibacterial drugs against Propionibacterium acnes between the values at baseline and at week 52, suggesting that long-term use did not result in changes in the drug sensitivity. The incidence of adverse events was 84.0% in the 2.5% BPO group and 87.2% in the 5% BPO group. Many of the adverse events occurred within the first month and were mild or moderate in severity and transient. The results suggest that both 2.5% and 5% BPO gels are effective and safe for long-term treatment of patients with acne vulgaris. © 2017 The Authors.

    Full Text Available The World Health Organization recommends intermittent preventive treatment in pregnancy (IPTp with sulfadoxine-pyrimethamine (SP in African regions with moderate to high malaria transmission. However, growing resistance to SP threatens the effectiveness of IPTp-SP, and alternative drugs are needed. This study tested the efficacy, tolerability, and safety of a fixed-dose combination azithromycin-chloroquine (AZCQ; 250 mg AZ/155 mg CQ base for IPTp relative to IPTp-SP.A randomized, Phase 3, open-label, multi-center study was conducted in sub-Saharan Africa (Benin, Kenya, Malawi, Tanzania, and Uganda between October 2010 and November 2013. Pregnant women received 3 IPTp courses with AZCQ (each course: 1,000/620 mg AZCQ QD for 3 days or SP (each course 1,500/75 mg SP QD for 1 day at 4- to 8-week intervals during the second and third trimester. Long-lasting insecticide-treated bednets were also provided at enrollment. Study participants were followed up until day 28 post delivery (time window: day 28-42. The primary endpoint was the proportion of participants with sub-optimal pregnancy outcomes (a composite endpoint comprising live-borne neonates with low birth weight [LBW, 28 weeks], abortion [≤28 weeks], lost to follow-up prior to observation of pregnancy outcome, or missing birth weight. The study was terminated early after recruitment of 2,891 of the planned 5,044 participants, due to futility observed in a pre-specified 35% interim analysis. In the final intent-to-treat dataset, 378/1,445 (26.2% participants in the AZCQ and 342/1,445 (23.7% in the SP group had sub-optimal pregnancy outcomes, with an estimated risk ratio (RR of 1.11 (95% CI: 0.97, 1.25; p = 0.12. There was no significant difference in the incidence of LBW between treatment groups (57/1138 [5.0%] in the AZCQ group, 68/1188 [5.7%] in the SP group, RR 0.87 [95% CI: 0.62, 1.23]; p = 0.44.

    Full Text Available In Africa, most plasmodium infections during pregnancy remain asymptomatic, yet are associated with maternal anemia and low birthweight. WHO recommends intermittent preventive therapy in pregnancy with sulfadoxine-pyrimethamine (IPTp-SP. However, sulfadoxine-pyrimethamine (SP efficacy is threatened by high-level parasite resistance. We conducted a trial to evaluate the efficacy and safety of scheduled intermittent screening with malaria rapid diagnostic tests (RDTs and treatment of RDT-positive women with dihydroartemisinin-piperaquine (DP as an alternative strategy to IPTp-SP.This was an open-label, two-arm individually randomized superiority trial among HIV-seronegative women at three sites in Malawi with high SP resistance. The intervention consisted of three or four scheduled visits in the second and third trimester, 4 to 6 wk apart. Women in the IPTp-SP arm received SP at each visit. Women in the intermittent screening and treatment in pregnancy with DP (ISTp-DP arm were screened for malaria at every visit and treated with DP if RDT-positive. The primary outcomes were adverse live birth outcome (composite of small for gestational age, low birthweight [<2,500 g], or preterm birth [<37 wk] in paucigravidae (first or second pregnancy and maternal or placental plasmodium infection at delivery in multigravidae (third pregnancy or higher.

    Icotinib has been previously shown to be non-inferior to gefitinib in non-selected advanced non-small-cell lung cancer patients when given as second- or further-line treatment. In this open-label, randomized, phase 3 CONVINCE trial, we assessed the efficacy and safety of first-line icotinib versus cisplatin/pemetrexed plus pemetrexed maintenance in lung adenocarcinoma patients with epidermal growth factor receptor (EGFR) mutation. Eligible participants were adults with stage IIIB/IV lung adenocarcinoma and exon 19/21 EGFR mutations. Participants were randomly allocated (1 : 1) to receive oral icotinib or 3-week cycle of cisplatin plus pemetrexed for up to four cycles; non-progressive patients after four cycles were maintained with pemetrexed until disease progression or intolerable toxicity. The primary end point was progression-free survival (PFS) assessed by independent response evaluation committee. Other end points included overall survival (OS) and safety. Between January 2013 and August 2014, 296 patients were randomized, and 285 patients were treated (148 to icotinib, 137 to chemotherapy). Independent response evaluation committee-assessed PFS was significantly longer in the icotinib group (11.2 versus 7.9 months; hazard ratio, 0.61, 95% confidence interval 0.43-0.87; P = 0.006). No significant difference for OS was observed between treatments in the overall population or in EGFR-mutated subgroups (exon 19 Del/21 L858R). The most common grade 3 or 4 adverse events (AEs) in the icotinib group were rash (14.8%) and diarrhea (7.4%), compared with nausea (45.9%), vomiting (29.2%), and neutropenia (10.9%) in the chemotherapy group. AEs (79.1% versus 94.2%; P icotinib group than in the chemotherapy group. First-line icotinib significantly improves PFS of advanced lung adenocarcinoma patients with EGFR mutation with a tolerable and manageable safety profile. Icotinib should be considered as a first-line treatment for this patient population. © The Author

    The newer ocular hypotensive agents available to treat glaucoma and ocular hypertension (OHT) include latanoprost, a prostaglandin F(2alpha) analogue, and the fixed combination of dorzolamide hydrochloride, a carbonic anhydrase inhibitor, and timolol maleate, a beta-blocker. The aim of this study was to compare the efficacy and tolerability of latanoprost with that of the fixed combination of dorzolamide and timolol over 8 weeks. This interventional, 8-week, randomized, open-label, parallel-group study was conducted at 18 centers in 6 Latin American countries. Patients with unilateral or bilateral primary open-angle, pigmentary, or exfoliative glaucoma or OHT were randomized to receive latanoprost, 1 drop in the affected eye QD (evening), or fixed-combination dorzolamide/timolol, 1 drop in the affected eye BID (morning and evening). Medications were self-administered, 1 drop per affected eye. At baseline and week 8, intraocular pressure (IOP) was measured 3 times each at 8:30 am, 10:00 am, 2:00 pm, and 5:00 pm and after the water-drinking test, which estimates the IOP peak of diurnal tension curve, performed following the 5:00 pm IOP assessment. The primary efficacy outcome was change in diurnal IOP (the mean of IOP measurements) from baseline to week 8. Adverse effect (AE) data were recorded at each visit. A total of 229 patients were randomized (latanoprost, n = 112; dorzolamide/timolol, n = 117). Mean baseline diurnal IOP values were similar between the 2 groups. Mean (SD) diurnal IOP reductions at week 8 before the water-drinking test were 6.9 (3.0) mm Hg for the latanoprost group and 6.4 (3.2) mm Hg for the dorzolamide/timolol group. Mean IOP values were similar at all time points except at 5:00 pm, when levels were significantly lower in latanoprost-treated patients (P = 0.025). After the water-drinking test, the increase in IOP values was similar between groups at baseline but lower in latanoprost-treated patients at week 8 (adjusted difference, 1.08 mm Hg

    Premixed insulins are recommended starter insulins in Chinese patients after oral antihyperglycemic medication (OAM) failure. In the present study, we compared the efficacy and safety of insulin lispro mix 25 (LM25) twice daily (b.i.d.) and insulin lispro mix 50 (LM50) b.i.d. as a starter insulin regimen in Chinese patients with type 2 diabetes mellitus (T2DM) who had inadequate glycemic control with OAMs. The primary efficacy outcome in the present open-label parallel randomized clinical trial was change in HbA1c from baseline to 26 weeks. Patients were randomized in a ratio of 1:  1 to LM25 (n = 80) or LM50 (n = 76). A mixed-effects model with repeated measures was used to analyze continuous variables. The Cochran-Mantel-Haenszel test with stratification factor was used to analyze categorical variables. At the end of the study, LM50 was more efficacious than LM25 in reducing mean HbA1c levels (least-squares [LS] mean difference 0.48; 95 % confidence interval [CI] 0.22, 0.74; P 1). More subjects in the LM50 than LM25 group achieved HbA1c targets of 1) or ≤6.5 % (52.6 % vs 20.0 %; P 1). Furthermore, LM50 was more effective than LM25 at reducing HbA1c in patients with baseline HbA1c, blood glucose excursion, and postprandial glucose greater than or equal to median levels (P ≤ 0.001). The rate and incidence of hypoglycemic episodes and increase in weight at the end of the study were similar between treatment groups. In Chinese patients with T2DM, LM50 was more efficacious than LM25 as a starter insulin. © 2016 The Authors.

    Palonosetron is the second-generation 5-hydroxytryptamine 3 receptor antagonist (5-HT3RA) that has shown better efficacy than the first-generation 5-HT3RA for prevention of chemotherapy-induced nausea and vomiting (CINV) in patients receiving moderately emetogenic chemotherapy (MEC). Granisetron transdermal delivery system (GTDS), a novel transdermal formulation, was developed to deliver granisetron continuously over 7 days. This study compared the efficacy and tolerability of the GTDS to palonosetron for the control of CINV following MEC. A total of 196 patients were randomized to GP or PG group. In this multicenter, randomized, open-label, cross-over, active-controlled, Phase IV study, GP group was assigned to receive transdermal granisetron (one GTDS patch, 7 days) in the first chemotherapy cycle, palonosetron (iv 0.25 mg/day, 1 days) in the second chemotherapy cycle before receiving MEC, and PG group was assigned to receive palonosetron in the first cycle and GTDS in the second cycle. Primary endpoint was the percentage of chemotherapy cycles achieving complete response (CR; defined as no emetic episodes and no rescue medication use) during the acute phase (0-24 h in post-chemotherapy; non-inferiority comparison with palonosetron). Total 333 cycles (165 in GTDS and 168 in palonosetron) were included in the per protocol analysis. The GTDS cycles showed non-inferiority to palonosetron cycles during the acute phase: CR was achieved by 124 (75.2 %) patients in the GTDS cycles and 134 (79.8 %) patients in the palonosetron cycles (treatment difference, -4.6 %; 95 % confidence interval, -13.6-4.4). There was no significant difference in CR rate during acute phase after the end of the first and second chemotherapy cycle between GP and PG group (p = 0.405, p = 0.074). Patients' satisfaction, assessed using Functional Living Index-Emesis (FLI-E), GTDS cycle were higher than those of palonosetron cycle in GP group (FLI-E score; median 1549.5 in GTDS cycle, median 1670

The condition can be treated using proton pump inhibitors (PPIs that act by irreversibly blocking the H+,K+-ATPase responsible for acid secretion. Vonoprazan is a K+ competitive channel inhibitor, which reversibly and potently inhibits gastric acid secretion. However, long-term data on vonoprazan use are limited. The aim of the VISION trial is to investigate the long-term efficacy and safety of vonoprazan in comparison with the PPI lansoprazole. This randomized, multicenter, 5-year, open-label study has a planned recruitment of 195 participants (2:1 allocation vonoprazan:lansoprazole from 33 sites in Japan. The study comprises an 8-week “healing” phase (vonoprazan 20 mg or lansoprazole 30 mg p.o. and a 260-week “maintenance” phase (vonoprazan 10 mg or lansoprazole 15 mg.

    Purpose This multicenter, randomized, open-label, phase III trial compared the efficacy and safety of decitabine with treatment choice (TC) in older patients with newly diagnosed acute myeloid leukemia (AML) and poor- or intermediate-risk cytogenetics. Patients and Methods Patients (N = 485) age ≥ 65 years were randomly assigned 1:1 to receive decitabine 20 mg/m2 per day as a 1-hour intravenous infusion for five consecutive days every 4 weeks or TC (supportive care or cytarabine 20 mg/m2 per day as a subcutaneous injection for 10 consecutive days every 4 weeks). The primary end point was overall survival (OS); the secondary end point was the complete remission (CR) rate plus the CR rate without platelet recovery (CRp). Adverse events (AEs) were recorded. Results The primary analysis with 396 deaths (81.6%) showed a nonsignificant increase in median OS with decitabine (7.7 months; 95% CI, 6.2 to 9.2) versus TC (5.0 months; 95% CI, 4.3 to 6.3; P = .108; hazard ratio [HR], 0.85; 95% CI, 0.69 to 1.04). An unplanned analysis with 446 deaths (92%) indicated the same median OS (HR, 0.82; 95% CI, 0.68 to 0.99; nominal P = .037). The CR rate plus CRp was 17.8% with decitabine versus 7.8% with TC (odds ratio, 2.5; 95% CI, 1.4 to 4.8; P = .001). AEs were similar for decitabine and cytarabine, although patients received a median of four cycles of decitabine versus two cycles of TC. The most common drug-related AEs with decitabine were thrombocytopenia (27%) and neutropenia (24%). Conclusion In older patients with AML, decitabine improved response rates compared with standard therapies without major differences in safety. An unplanned survival analysis showed a benefit for decitabine, which was not observed at the time of the primary analysis. PMID:22689805

    Chlorphenesin carbamate is a skeletal muscle relaxant approved in Korea for use in the treatment of pain and discomfort related to skeletal muscle trauma and inflammation. The aim of this study was to assess the bioequivalence of a generic formulation of chlorphenesin carbamate at doses of 250 and 500 mg and 2 branded formulations of the same doses in healthy Korean adults. This single-dose, randomized-sequence, open-label, 2-period crossover study was conducted in healthy Korean male and female volunteers. Subjects were assigned to receive, in a randomized sequence, a single dose of the generic (test) and branded (reference) formulations of chlorphenesin carbamate at a dose of 250 or 500 mg. Blood samples were drawn at 0, 0.33, 0.67, 1, 1.5, 2, 3, 4, 6, 9, 12, and 15 hours after administration. Pharmacokinetic properties (C(max), T(max), AUC(0-t) AUC(0-infinity), t(1/2), and ke) were determined using HPLC. The formulations were to be considered bioequivalent if the 90% CIs of the treatment ratios of the geometric means of C(max) and AUC(0-t) were within a predetermined range of log 0.80 to log 1.25 based on regulatory criteria. Tolerability was assessed by monitoring for adverse events (AEs) on physical examination and/or e-mail and personal interview at the beginning and end of each study period. Twenty-eight subjects (22 men, 6 women) received chlorphenesin carbamate at the 250-mg dose, and 24 male subjects received the 500-mg dose. The mean (SD) ages of the subjects were 24.0 (2.6) and 24.0 (1.9) years in the 250- and 500-mg groups, respectively. No significant differences were found between the test and reference formulations (90% CIs: C(max), 1.0048-1.1153 with the 250-mg dose and 0.9630-1.1189 with the 500-mg dose; AUC(0-t), 0.9882-1.0546 and 0.9842-1.0578, respectively).

    Full Text Available Abstract Background Bleeding severity, anatomic location, tissue characteristics, and visibility are common challenges encountered while managing intraoperative bleeding, and conventional hemostatic measures (suture, ligature, and cautery may sometimes be ineffective or impractical. While topical absorbable hemostats (TAH are useful hemostatic adjuvants, each TAH has associated disadvantages. Methods We evaluated the safety and hemostatic efficacy of a new advanced biologic combination product―fibrin pad―to potentially address some gaps associated with TAHs. Fibrin pad was assessed as adjunctive hemostat in open partial nephrectomy in single-center, open-label, Phase I study (N = 10, and as primary hemostat in multicenter, single-blind, randomized, standard-of-care (SOC-controlled Phase I/II study (N = 7 in Israel. It was used to control mild-to-moderate bleeding in Phase I and also spurting arterial bleeding in Phase I/II study. Phase I study assessed safety and Phase I/II study, proportion of successes at 10 min following randomization, analyzed by Fisher exact tests at 5% significance level. Results Phase I (N = 10: All patients completed the study. Hemostasis was achieved within 3–4 min (average = 3.1 min of a single application in all patients. Fibrin pad was found to be safe for human use, with no product-related adverse events reported. Phase I/II (N = 7: Hemostatic success at 10 min (primary endpoint was achieved in 3/4 patients treated with fibrin pad versus 0/3 patients treated with SOC. No clinically significant change in laboratory or coagulation parameters was recorded, except a case of post-procedural hemorrhage with fibrin pad, which was considered serious and related to the fibrin pad treatment, and required re-operation. Although Data Safety Monitoring Board authorized trial continuation, the sponsor decided against proceeding toward an indication for primary treatment of severe arterial

    Sodium lactate seemed to improve fluid balance and avoid fluid overload. The objective of this study was to determine if these beneficial effects can be at least partly explained by an improvement in disseminated intravascular coagulation (DIC)-associated renal microvascular thrombosis. Ancillary work of an interventional randomized open label controlled experimental study. Fifteen female "Large White" pigs (2 months old) were challenged with intravenous infusion of E. coli endotoxin. Three groups of five animals were randomly assigned to receive different fluids: a treatment group received sodium lactate 11.2% (SL group); an isotonic control group received 0.9% NaCl (NC group); a hypertonic control group, with the same amount of osmoles and sodium than SL group, received sodium bicarbonate 8.4% (SB group). Glomerular filtration rate (GFR) markers, coagulation and inflammation parameters were measured over a 5-h period. Immediately after euthanasia, kidneys were withdrawn for histological study. Statistical analysis was performed with nonparametric tests and the Dunn correction for multiple comparisons. A p < 0.05 was considered significant. The direct immunofluorescence study revealed that the percentage of capillary sections thrombosed in glomerulus were significantly lesser in SL group [5 (0-28) %] compared to NC [64 (43-79) %, p = 0.01] and SB [64 (43-79), p = 0.03] groups. Alterations in platelet count and fibrinogen level occurred earlier and were significantly more pronounced in both control groups compared to SL group (p < 0.05 at 210 and 300 min). The increase in thrombin-antithrombin complexes was significantly higher in NC [754 (367-945) μg/mL; p = 0.03] and SB [463 (249-592) μg/mL; p = 0.03] groups than in SL group [176 (37-265) μg/mL]. At the end of the experiment, creatinine clearance was significantly higher in SL group [55.46 (30.07-67.85) mL/min] compared to NC group [1.52 (0.17-27.67) mL/min, p = 0.03]. In this study, we

    The present study was a prospective, parallel group, open-labeled, comparative, multicentric, active controlled study to evaluate the safety, tolerability and benefits of fixed dose combination of acarbose and metformin versus metformin alone in type 2 diabetic patients. A total of 229 patients with type 2 diabetes were enrolled at 5 medical centers across India. They received either acarbose (50 mg) + metformin (500 mg) bid/tid (n=115) or metformin monotherapy (500 mg) bid/ tid (n=114) for 12 weeks. Primary objective was to evaluate safety and tolerability based on the adverse events reported. Secondary objective was efficacy assessment based on changes in fasting, post prandial blood glucose and HbA1c values. In the acarbose + metformin group 10 patients reported 14 adverse events while in metformin group 9 patients reported 10 adverse events. No patient reported any serious adverse event or was withdraw from study because of adverse events. In the acarbose plus metformin group fasting blood glucose (FBG) decreased from a baseline of 158.85 +/- 18.14 mg/dl to 113.55 +/- 19.38 mg/dl (p fasting blood glucose decreased from a baseline of 158.31 +/- 26.53 mg/dl to 130.55 +/- 28.31 mg/dl (p < 0.0001) (decrease of 27.76 +/- 22.91 mg/dl) at 12 weeks. In the acarbose plus metformin group postprandial blood glucose (PPBG) decreased from a baseline of 264.65 +/- 34.03 mg/dl to 173.22 +/- 31.40 mg/dl (p < 0.0001) (decrease of 91.43 +/- 28.65 mg/dl) at 12 weeks, while in the metformin group PPBG decreased from a baseline of 253.56 +/- 36.28 mg/dl to 205.36 +/- 39.49 mg/dl (p < 0.0001) (decrease of 48.20 +/- 32.72 mg/dl) at 12 weeks. In the acarbose plus metformin group glycosylated haemoglobin (HbA1c) decreased from a baseline of 9.47 +/- 0.69% to 7.71 +/- 0.85% (p < 0.0001) (% decrease of 1.76 +/- 1.11) at 12 weeks, while in the metformin group HbAlc decreased from a baseline of 9.32 +/- 0.65% to 8.26 +/- 0.68% (p < 0.0001) (% decrease of 1.06 +/- 0.66) at 12 weeks.

    In phase III trials, 2 doses of a herpes zoster (HZ) subunit vaccine (HZ/su; 50 µg varicella-zoster virus glycoprotein E [gE] and AS01 B Adjuvant System) administered 2-months apart in older adults (≥50 and ≥70 years) demonstrated >90% efficacy in preventing HZ and had a clinically acceptable safety profile. Here we report immunogenicity, reactogenicity and safety following administration of 2 HZ/su doses at intervals longer than 2 months. In this Phase III, open-label trial conducted in the US and Estonia, 354 adults ≥50 years were randomized 1:1:1 to receive 2 HZ/su doses 2, 6, or 12 months apart. gE-specific humoral immune responses were evaluated at pre-vaccination, 1 and 12 months post-dose 2. Co-primary objectives were to compare immune responses to HZ/su 1 month post-dose 2 when given 6-months or 12-months apart to those administered 2-months apart. For each participant, safety information was collected from dose 1 to 12 months post-dose 2. 346 participants completed the study and 343 were included in the according-to-protocol cohort for immunogenicity. One month post-dose 2, vaccine response rates were 96.5% (97.5% confidence interval [CI]: 90.4; 99.2) and 94.5% (97.5% CI: 87.6; 98.3) for the 0, 6- and 0, 12-month schedules, respectively, both schedules meeting the pre-defined criterion. Non-inferiority of anti-gE geometric mean concentrations was demonstrated for HZ/su administered on 0, 6-month compared to a 0, 2-month schedule; however, HZ/su administered on a 0, 12-month schedule did not meet the non-inferiority criterion. Injection site pain was the most commonly reported solicited adverse event (AE). 26 participants each reported at least 1 serious AE; none were assessed as related to vaccination. Immune responses to HZ/su administered at 0, 6-month were non-inferior to those elicited by a 0, 2-month schedule. HZ/su exhibited a clinically acceptable safety profile for all dosing intervals.

    This open-label, phase lll trial compared chemoradiation followed by surgery with or without neoadjuvant and adjuvant cetuximab in patients with resectable esophageal carcinoma. Patients were randomly assigned (1:1) to 2 cycles of chemotherapy (docetaxel 75 mg/m2, cisplatin 75 mg/m2) followed by chemoradiation (45 Gy, docetaxel 20 mg/m2 and cisplatin 25 mg/m2, weekly for 5 weeks) and surgery, with or without neoadjuvant cetuximab 250 mg/m2 weekly and adjuvant cetuximab 500 mg/m2 fortnightly for 3 months. The primary endpoint was progression-free survival (PFS). In total, 300 patients (median age, 61 years; 88% male; 63% adenocarcinoma; 85% cT3/4a, 90% cN+) were assigned to cetuximab (n = 149) or control (n = 151). The R0-resection rate was 95% for cetuximab versus 97% for control. Postoperative treatment-related mortality was 6% in both arms. Median PFS was 2.9 years (95% CI, 2.0 to not reached) with cetuximab and 2.0 years (95% CI, 1.5 to 2.8) with control (HR, 0.79; 95% CI, 0.58 to 1.07; P = .13). Median overall survival (OS) time was 5.1 years (95% CI, 3.7 to not reached) versus 3.0 years (95% CI, 2.2 to 4.2) for cetuximab and control, respectively (HR, 0.73; 95% CI, 0.52 to 1.01; P = .055). Time to loco-regional failure after R0-resection was significantly longer for cetuximab (HR 0.53; 95% CI, 0.31 to 0.90; P = .017); time to distant failure did not differ between arms (HR, 1.01; 95% CI, 0.64 to 1.59, P = .97). Cetuximab did not increase adverse events in neoadjuvant or postoperative settings. Adding cetuximab to multimodal therapy significantly improved loco-regional control, and led to clinically relevant, but not-significant improvements in PFS and OS in resectable esophageal carcinoma.

    A controlled-release (CR) formulation of simvastatin was recently developed in Korea. The formulation is expected to yield a lower C(max) and similar AUC values compared with the immediate-release (IR) formulation. The goal of this study was to compare the pharmacokinetics of the new CR formulation and an IR formulation of simvastatin after single- and multiple-dose administration in healthy Korean subjects. This study was developed as part of a product development project at the request of the Korean regulatory agency. This was a randomized, open-label, parallelgroup, 2-part study. Eligible subjects were healthy male or female volunteers between the ages of 19 and 55 years and within 20% of their ideal weight. In part I, each subject received a single dose of the CR or IR formulation of simvastatin 40 mg orally (20 mg x 2 tablets) after fasting. In part II, each subject received the same dose of the CR or IR formulation for 8 consecutive days. Blood samples were obtained for 48 hours after the dose in part I and after the first and the last dose in part II. Pharmacokinetic parameters were determined for both simvastatin (the inactive prodrug) and simvastatin acid (the active moiety). An adverse event (AE) was defined as any unfavorable sign (including an abnormal laboratory finding) or symptom, regardless of whether it had a causal relationship with the study medication. Serious AEs were defined as any events that are considered life threatening, require hospitalization or prolongation of existing hospitalization, cause persistent or significant disability or incapacity, or result in congenital abnormality, birth defect, or death. AEs were determined based on patient interviews and physical examinations. Twenty-four healthy subjects (17 men, 7 women; mean [SD] age, 29 [7] years; age range, 22-50 years) were enrolled in part I, and 29 subjects (17 men, 12 women; mean age, 33 [9] years; age range, 19-55 years) were enrolled in part II. For simvastatin acid, C

    Imatinib is a tyrosine kinase inhibitor that has been established as a highly effective therapy for chronic myelogenous leukemia and gastrointestinal stromal tumors. A new generic, once-daily 400-mg tablet of imatinib has been developed by a pharmaceutical company in Argentina, where the regulatory standard for marketing authorization of an imatinib generic is in vitro dissolution testing. The aim of this study was to assess the bioequivalence of a new generic film-coated test tablet formulation versus a film-coated reference tablet formulation of imatinib 400 mg. The local manufacturer seeks to validate the in vitro performance of this new formulation with a bioequivalence study. A randomized, open-label, single-dose, fasting, 2-period, 2-sequence crossover design with a 2-week washout period was used in this study. The study population consisted of healthy male South American (Uruguayan) volunteers, who were assigned in a 1:1 ratio to a randomized sequence (test-reference or reference-test). In each period, the test or reference formulation was administered after an overnight fast. During the 72-hour follow-up period, participants were monitored for vital signs and symptoms. Blood samples were collected at 15 time points, including baseline, until 72 hours. Physical examination and laboratory tests (blood, urine) were repeated 1 week after study completion. A noncompartmental model was used to determine the pharmacokinetic parameters of imatinib. The 90% CIs of the test/reference ratios for AUC(0-infinity) and C(max) were determined; the test and reference formulations were considered bioequivalent if the 90% CIs were between 0.80 and 1.25. Adverse events were assessed by a nurse who administered a questionnaire while the healthy volunteers were admitted in the unit. The bioequivalence study was conducted in 30 Uruguayan male volunteers. Demographic characteristics (mean [SD]) included age, 27.8 (6.5) years; weight, 71.2 (9.8) kg; height, 1.71 (0.09) m; and body

    A sprinkle capsule formulation containing enteric-coated, delayed-release rabeprazole granules is being developed for the treatment of children with gastrointestinal reflux disease. The granules are designed to be mixed with vehicles that facilitate delivery to children, who may be unable to swallow solid formulations. The primary objective of this study-conducted on the sponsor's initiative-was to compare the bioavailability of rabeprazole granules when mixed with various dosing vehicles (small amount of soft food or infant formula) with that of a rabeprazole suspension with inactive vehicle granules (reference), to determine which dosing vehicle can be used to deliver rabeprazole in children. Tolerability was also assessed. This single-center, single-dose, randomized, open-label, 5-period crossover study was conducted in 35 healthy adult subjects. In a randomized sequence, fasting subjects received a single dose of 10-mg rabeprazole granules per treatment period, mixed with small amounts of 1 of 5 dosing vehicles (a strawberry-flavored suspension of rabeprazole granules with inactive vehicle granules reconstituted with water, yogurt [1 tablespoon], applesauce [1 tablespoon], or infant formula [5 mL], or a suspension of rabeprazole granules with inactive vehicle tablet reconstituted with water). Full plasma pharmacokinetic (PK) profiles of rabeprazole and its thioether metabolite were collected; concentrations were estimated via LC-MS/MS. PK properties were estimated using noncompartmental methods; 90% CIs around least squares mean test-to-reference ratios were calculated for C(max) and AUC values. All treatment-emergent adverse events (TEAEs) were recorded and assessed for severity (mild, moderate, or severe) and relationship to study drug. A total of 35 subjects were enrolled (mean age, 38 years; 54.3% female; 100% white; mean weight, 71.4 kg). Thirty-four subjects completed the study. Rabeprazole and rabeprazole thioether plasma PK properties were comparable

    Acetylcysteine may be used as a muco- lytic agent for the treatment of chronic bronchitis, chronic obstructive pulmonary disease, and other pulmonary diseases complicated by the production of viscous mucus. However, little is known of its pharmacokinetic properties when given orally in healthy volunteers, particularly in a Chinese Han population. This study was conducted to provide support for the marketing of a generic product in China. The purpose of this study was to compare the pharmacokinetics and relative bioavailability of a generic test formulation and a branded reference formulation of acetylcysteine in fasting healthy Chinese male volunteers. A single-dose, open-label, randomized-sequence, 2-period crossover design with a 7-day washout period between doses was used in this study. Healthy Chinese male nonsmokers aged 18 to 40 years with a body mass index (BMI) of 19 to 25 kg/m(2) were selected. Eligible volunteers were randomly assigned to receive acetylcysteine 600 mg PO as either the test formulation (3 tablets of 200 mg each) or reference formulation (1 tablet of 600 mg) under fasting conditions. A total of 15 serial blood samples were collected over a 24-hour interval, and total plasma acetylcysteine concentrations were analyzed by a validated liquid chromatography-isotopic dilution mass spectrometry method. Pharmacokinetic parameters (C(max), T(max), t(½) AUC(0-t), and AUC(0-∞) were calculated and analyzed statistically. The 2 formulations were considered bioequivalent if the 90% CIs of the log-transformed ratios (test/reference) of C(max) and AUC were within the predetermined bioequivalence ranges (70%-143% for C(max); 80%-125% for AUC), as established by the State Food and Drug Administration of China. Tolerability was determined by vital signs, clinical laboratory tests, 12-lead ECGs, physical examinations, and interviews with the subjects about adverse events (AEs). A total of 24 healthy Chinese Han male volunteers were enrolled in and

    Risperidone is a benzisoxazole derivate and is effective in the treatment of schizophrenia and other psychiatric illnesses in adults and children. Although there are a few reports in the literature regarding the pharmacokinetic characteristics of risperidone, insufficient data on its pharmacokinetic properties in a Chinese population are available. To meet the requirements for marketing a new generic product, this study was designed to compare the pharmacokinetic properties and bioequivalence of two 2 mg tablet formulations of risperidone: a newly developed generic formulation (test) and a branded formulation (reference) in healthy adult male Chinese volunteers. A single-dose, open-label, randomized-sequence, 2 × 2 crossover study was conducted in fasted healthy male Chinese volunteers. Eligible participants were randomly assigned in a 1:1 ratio to receive 1 tablet (2 mg each) of the test formulation (Risperidone tablet; Dr. Reddy's Laboratories Ltd., Hyderabad, India) or the reference formulation (Risperdal(®) tablet; Xian-Janssen Pharmaceutical Ltd., Xi-an, China), followed by a 2-week washout period and subsequent administration of the alternate formulation. The study drugs were administered after a 10-hour overnight fast. Plasma samples were collected over 96 hours. Plasma concentrations of the parent drug, risperidone, and its active metabolite, 9-hydroxy-risperidone, were analyzed by a liquid chromatography-tandem mass spectrometry method. The formulations would be considered bioequivalent if the 90% confidence intervals (CIs) of the natural log-transformed values were within the predetermined 80-125% equivalence range for the maximum plasma drug concentration (Cmax) and the area under the plasma concentration-time curve (AUC), in accordance with guidelines issued by the US Food and Drug Administration. Assessment of tolerability was based on recording of adverse events (AEs), monitoring of vital signs, electrocardiograms, and laboratory tests at baseline

    Risperidone (RSP) is a benzisoxazole antipsychotic agent used to treat schizophrenia and other psychiatric illnesses in adults and children (including those with autism). After oral administration, RSP is completely absorbed from the gastrointestinal tract and undergoes hydroxylation to yield 9-hydroxyrisperidone (9-OH-RSP), an active metabolite that has a pharmacologic profile and potency similar to RSP. The aims of this study were to compare the relative bioavailability of a pharmaceutical-equivalent (test) formulation with a reference formulation of oral RSP 2 mg, both available commercially on the Brazilian pharmaceutical market, and to generate data regarding the oral bioavailability of the tested drug in healthy Brazilian volunteers. This single-dose, randomized-sequence, open-label, 2-period crossover study was conducted in healthy Brazilian volunteers from August to December 2008. Subjects were randomly assigned to receive the test formulation followed by the reference formulation or vice versa, with a 30-day washout period between doses. Study drugs were administered after a 12-hour overnight fast. For pharmacokinetic analysis, blood samples were drawn at 0 (baseline), 0.25, 0.5, 1, 1.5, 3, 5, 8, 12, 24, 48, 72, 96, and 120 hours after administration. Plasma concentrations of RSP and 9-OH-RSP were determined using LC-MS/MS. The test and reference formulations were to be considered bioequivalent if the 90% CIs for the geometric mean test/reference ratios were within a predetermined range of 80% to 125%, in accordance with the policies of the Brazilian Sanitary Surveillance Agency and the US Food and Drug Administration. Tolerability was determined using clinical assessments, monitoring of vital signs, analysis of laboratory test results, and subject interviews regarding adverse events. A total of 22 subjects were enrolled (11 men, 11 women; mean [SD] age, 32 [12] years [range, 1858 years]; weight, 70.4 [11.9] kg [range, 50-103 kg]; height, 1.67 [0.08] m

    A sustained-release (SR) formulation of cilostazol was recently developed in Korea and was expected to yield a lower C(max) and a similar AUC to the immediate-release (IR) formulation. The goal of the present study was to compare the pharmacokinetic profiles of a newly developed SR formulation and an IR formulation of cilostazol after single- and multiple-dose administration and to evaluate the influence of food in healthy Korean subjects. This study was developed as part of a product development project at the request of the Korean regulatory agency. This was a randomized, 3-part, sequential, open-label, 2-period crossover study. Each part consisted of different subjects between the ages of 19 and 55 years. In part 1, each subject received a single dose of SR (200 mg × 1 tablet, once daily) and IR (100 mg × 2 tablets, BID) formulations of cilostazol orally 7 days apart in a fasted state. In part 2, each subject received a single dose of the SR (200 mg × 1 tablet, once daily) formulation of cilostazol 7 days apart in a fasted and a fed state. In part 3, each subject received multiple doses of the 2 formulations for 8 consecutive days 21 days apart. Blood samples were taken for 72 hours after the dose. Cilostazol pharmacokinetics were determined for both the parent drug and its metabolites (OPC-13015 and OPC-13213). Adverse events were evaluated through interviews and physical examinations. Among the 92 enrolled subjects (66 men, 26 women; part 1, n = 26; part 2, n = 26; part 3, n = 40), 87 completed the study. In part 1, all the primary pharmacokinetic parameters satisfied the criterion for assumed bioequivalence both in cilostazol and its metabolites, yielding 90% CI ratios of 0.9624 to 1.2323, 0.8873 to 1.1208, and 0.8919 to 1.1283 for C(max) and 0.8370 to 1.0134, 0.8204 to 0.9807, and 0.8134 to 0.9699 for AUC(0-last) of cilostazol, OPC-13015, and OPC-13213, respectively. In part 2, food intake increased C(max) and AUC significantly (P food and 23 with a high

    The number of open-label extension studies being performed has increased enormously in recent years. Often it is difficult to differentiate between these extension studies and the double-blind, controlled studies that preceded them. If undertaken primarily to gather more patient-years of exposure to the new drug in order to understand and gain confidence in its safety profile, open-label extension studies can play a useful and legitimate role in drug development and therapeutics. However, this can only occur if the open-label extension study is designed, executed, analysed and reported competently. Most of the value accrued in open-label extension studies is gained from a refinement in the perception of the expected incidence of adverse effects that have most likely already been identified as part of the preclinical and clinical trial programme. We still have to rely heavily on post-marketing safety surveillance systems to alert us to type B (unpredictable) adverse reactions because open-label extension studies are unlikely to provide useful information about these types of often serious and relatively rare adverse reactions. Random allocation into test and control groups is needed to produce precise incidence data on pharmacologically expected, or type A, adverse effects. Some increased confidence about incidence rates might result from the open-label extension study; however, as these studies are essentially uncontrolled and biased, the data are not of great value. Other benefits have been proposed to be gained from open-label extension studies. These include ongoing access to an effective but otherwise unobtainable medicine by the volunteers who participated in the phase III pivotal trials. However, there are unappreciated ethical issues about the appropriateness of enrolling patients whose response to previous treatment is uncertain, largely because treatment allocation in the preceding randomised, double-blind, controlled trial has not been revealed at the

    To investigate the effectiveness and safety of a symbiotic mixture in preventing recurrence of constipation-related abdominal pain in patients with uncomplicated diverticular disease of the colon. Forty-six consecutive patients (10 men, 36 women, mean age 62.5 years, range 49 to 77 years), previously affected by symptomatic uncomplicated diverticular disease of the colon, were enrolled in a 6-month follow-up study in a prospective, randomized, open-label study. The following symptoms were assessed at entry and through follow-up by using a quantitative scale: constipation, diarrhoea and abdominal pain. After recruitment, the patients were assigned to the following treatment: SCM-III symbiotic mixture, 10 ml three times a day. The colonization of ingested Lactobacillus acidophilus 145 and Bifidobacterium spp. 420 was assessed by species-specific PCR. Forty-five patients completed the study (97%). Thirty-one patients (68%) were still symptom free after the 6th month of treatment. Treatment with SCM-III was regarded as "effective" or "very effective" in more than 78% of the patients altogether (pdiverticular disease of the colon, especially in those patients with constipation-predominant features.

    To determine preliminarily whether donepezil will improve memory, behavior, and global function after chronic traumatic brain injury (TBI). Sixteen-week open-label study. Outpatient TBI rehabilitation program. Four patients with chronic, severe TBI. Donepezil 5mg daily for 8 weeks followed by 10mg daily for 4 weeks. Memory measures included the Rey Auditory Verbal Learning Test (RAVLT), the Complex Figure Test (CFT), items from the Rivermead Behavioural Memory Test (RBMT), and a semantic fluency task. The Neuropsychiatric Inventory (NPI) evaluated behavior and affect. Function was assessed by using the FIM instrument and a clinical global impression of change. On the RAVLT, the mean scores for learning and short- and long-term recall improved by 0.4, 1.04, and.83 standard deviations (SDs) above baseline, respectively. On the CFT, the mean scores for short-term recall and long-term recall improved by 1.56 and 1.38 SDs above baseline, respectively. A positive trend was observed on the RBMT and on the NPI subscales. Donepezil may improve some aspects of memory and behavior in persons with chronic TBI. Randomized clinical trials are required to support these preliminary findings.

    Accumulating evidence implicates gut microbiota as promising targets for the treatment of type 2 diabetes mellitus (T2DM). With a randomized clinical trial, we tested the hypothesis that alteration of gut microbiota may be involved in the alleviation of T2DM with hyperlipidemia by metformin and a specifically designed herbal formula (AMC). Four hundred fifty patients with T2DM and hyperlipidemia were randomly assigned to either the metformin- or AMC-treated group. After 12 weeks of treatment, 100 patients were randomly selected from each group and assessed for clinical improvement. The effects of the two drugs on the intestinal microbiota were evaluated by analyzing the V3 and V4 regions of the 16S rRNA gene by Illumina sequencing and multivariate statistical methods. Both metformin and AMC significantly alleviated hyperglycemia and hyperlipidemia and shifted gut microbiota structure in diabetic patients. They significantly increased a coabundant group represented by Blautia spp., which significantly correlated with the improvements in glucose and lipid homeostasis. However, AMC showed better efficacies in improving homeostasis model assessment of insulin resistance (HOMA-IR) and plasma triglyceride and also exerted a larger effect on gut microbiota. Furthermore, only AMC increased the coabundant group represented by Faecalibacterium spp., which was previously reported to be associated with the alleviation of T2DM in a randomized clinical trial. Metformin and the Chinese herbal formula may ameliorate type 2 diabetes with hyperlipidemia via enriching beneficial bacteria, such as Blautia and Faecalibacterium spp. IMPORTANCE Metabolic diseases such as T2DM and obesity have become a worldwide public health threat. Accumulating evidence indicates that gut microbiota can causatively arouse metabolic diseases, and thus the gut microbiota serves as a promising target for disease control. In this study, we evaluated the role of gut microbiota during improvements in

    Full Text Available Male involvement (MI is vital for the uptake of Prevention of Mother to Child Transmission (PMTCT of Human Immunodeficiency Virus (HIV interventions. Partner notification (PN is among the strategies identified for MI in PMTCT services. The purpose of this randomized controlled trial was to evaluate the efficacy of an invitation card to the male partners as a strategy for MI in PMTCT services by comparing the proportion of pregnant women that were accompanied by their partners between the intervention and the non-intervention study groups.Pregnant women attending antenatal care without a male partner at South Lunzu and Mpemba health centres in Blantyre, Malawi, were enrolled in the study from June to December 2013. In an intention-to-treat analysis, we compared all participants that were randomized in the invitation card group with the standard of care (SoC group. Risk ratios (RR with 95% confidence intervals (CI were computed to assess the efficacy of the invitation card.Of the 462 randomized women, 65/230 (28.26% of the women in the invitation card group reported to the antenatal care clinic with their partners compared to 44/232 (18.97% women in the SoC group.

    The results of the Iressa Pan-Asia Study (IPASS), which compared gefitinib and carboplatin/paclitaxel in previously untreated never-smokers and light ex-smokers with advanced pulmonary adenocarcinoma were published previously. This report presents overall survival (OS) and efficacy according to epidermal growth factor receptor (EGFR) biomarker status. In all, 1,217 patients were randomly assigned. Biomarkers analyzed were EGFR mutation (amplification mutation refractory system; 437 patients evaluable), EGFR gene copy number (fluorescent in situ hybridization; 406 patients evaluable), and EGFR protein expression (immunohistochemistry; 365 patients evaluable). OS analysis was performed at 78% maturity. A Cox proportional hazards model was used to assess biomarker status by randomly assigned treatment interactions for progression-free survival (PFS) and OS. OS (954 deaths) was similar for gefitinib and carboplatin/paclitaxel with no significant difference between treatments overall (hazard ratio [HR], 0.90; 95% CI, 0.79 to 1.02; P = .109) or in EGFR mutation-positive (HR, 1.00; 95% CI, 0.76 to 1.33; P = .990) or EGFR mutation-negative (HR, 1.18; 95% CI, 0.86 to 1.63; P = .309; treatment by EGFR mutation interaction P = .480) subgroups. A high proportion (64.3%) of EGFR mutation-positive patients randomly assigned to carboplatin/paclitaxel received subsequent EGFR tyrosine kinase inhibitors. PFS was significantly longer with gefitinib for patients whose tumors had both high EGFR gene copy number and EGFR mutation (HR, 0.48; 95% CI, 0.34 to 0.67) but significantly shorter when high EGFR gene copy number was not accompanied by EGFR mutation (HR, 3.85; 95% CI, 2.09 to 7.09). EGFR mutations are the strongest predictive biomarker for PFS and tumor response to first-line gefitinib versus carboplatin/paclitaxel. The predictive value of EGFR gene copy number was driven by coexisting EGFR mutation (post hoc analysis). Treatment-related differences observed for PFS in the EGFR

    This study compared barnidipine, a calcium-channel blocker, and benazepril, an angiotensin-converting enzyme inhibitor, in 85 Chinese patients with renal parenchymal hypertension (diastolic blood pressure range 95 - 110 mmHg). Patients were randomly assigned to receive either 10 mg barnidipine or 10 mg benazepril orally daily for 4 weeks. In patients with diastolic blood pressure > 90 mmHg after 2 weeks of treatment, the dose of barnidipine or benazepril was increased by 5 or 10 mg, respectively. Both the barnidipine-treated group (n = 43) and the benazepril-treated group (n = 42) showed significant mean reductions from baseline in sitting systolic and diastolic blood pressures. The decrease in diastolic blood pressure with benazepril was significantly greater than with barnidipine treatment. Sitting heart rate was not changed by either drug. There was no significant difference in adverse events between the two groups. Barnidipine is similar to benazepril for the treatment of renal parenchymal hypertension.

    Variable chemotherapy exposure may cause toxicity or lack of efficacy. This study was initiated to validate pharmacokinetically (PK)-guided paclitaxel dosing in patients with advanced non-small-cell lung cancer (NSCLC) to avoid supra- or subtherapeutic exposure. Patients with newly diagnosed, advanced NSCLC were randomly assigned to receive up to 6 cycles of 3-weekly carboplatin AUC 6 or cisplatin 80 mg/m(2) either with standard paclitaxel at 200 mg/m(2) (arm A) or PK-guided dosing of paclitaxel (arm B). In arm B, initial paclitaxel dose was adjusted to body surface area, age, sex, and subsequent doses were guided by neutropenia and previous-cycle paclitaxel exposure [time above a plasma concentration of 0.05 µM (Tc>0.05)] determined from a single blood sample on day 2. The primary end point was grade 4 neutropenia; secondary end points included neuropathy, radiological response, progression-free survival (PFS) and overall survival (OS).

    Patients with fibromyalgia frequently present with symptoms similar to those experienced by patients with gluten-related disorders, raising the possibility that a subgroup of these patients could be experiencing underlying gluten sensitivity. This study aimed to evaluate the effects of a gluten-free diet (GFD) compared with a hypocaloric diet (HCD) among patients with fibromyalgia. Adult patients diagnosed with fibromyalgia were randomly allocated to receive a GFD or a HCD over a 24-week period. The primary outcome measure was the change in the number of gluten sensitivity symptoms. The following secondary outcomes were evaluated: body mass index, Revised Fibromyalgia Impact Questionnaire, Pittsburgh Sleep Quality Index, Brief Pain Inventory, Beck Depression Inventory-II, State-Trait Anxiety Inventory, Short-Form Health Survey, Patient Global Impression Scale of Severity, Patient Global Impression Scale of Improvement, and adverse events. Seventy-five subjects were randomly allocated to receive either a GFD (n=35) or an HCD (n=40). The least squares mean change in the total number of gluten sensitivity symptoms from baseline did not differ significantly between the GFD and HCD groups (-2.44±0.40 for the GFD; -2.10±0.37 for the HCD; P=0.343). Similarly, the 2 dietary interventions did not differ in any of the remaining measured secondary outcomes. Both dietary interventions were well tolerated. Both dietary interventions were associated with similar beneficial outcomes in reducing gluten sensitivity symptoms and other secondary outcomes. However, despite its specificity, GFD was not superior to HCD in reducing the number of gluten sensitivity symptoms or secondary outcomes.

    The treatment of patients with severe malaria in sub-Saharan Africa has become a challenge to clinicians due to poor compliance to quinine and the increasing multidrug resistance to antimalarials by the P. falciparum parasite. The aim of this study was to compare the efficacy and safety profile of two truncated antimalarial regimens of intravenous quinine followed by oral Malarone (Malarone arm) with intravenous quinine followed by oral quinine (quinine arm) in the treatment of severe P. falciparum malaria. The outcome measures were parasite clearance time, fever clearance time, efficacy, and adverse events profile. Consecutive patients aged 1-60 years, with a diagnosis of severe malaria with positive blood smears for P. falciparum parasites and admitted to the Moi Teaching and Referral Hospital were randomized into the two study arms. Of the 360 patients studied 167 and 193 cases were randomized into the Malarone and quinine arms, respectively. Of the five (1.4 per cent) patients who died, three came from the quinine arm. The frequency of adverse reactions was higher in the oral quinine group (31.6 per cent) than in the Malarone group (25.7 per cent). The mean parasite clearance time was 120 h and 108 h for the quinine and Malarone arms of the study, respectively, and the mean fever clearance times were 84 h and 72 h for the quinine and Malarone arms, respectively (p=0.1). Truncated therapeutic regimen using malarone after intravenous quinine is safer and as effective as conventional intravenous quinine followed by oral quinine in the treatment of severe malaria. The P. falciparum recrudescence rate was lower with the use of Malarone than for quinine.

    Purpose To determine the effects of carfilzomib, lenalidomide, and dexamethasone (KRd) versus lenalidomide and dexamethasone (Rd) on health-related quality of life (HR-QoL) in the Carfilzomib, Lenalidomide, and Dexamethasone Versus Lenalidomide and Dexamethasone for the Treatment of Patients With Relapsed Multiple Myeloma (ASPIRE) trial. Methods Patients with relapsed multiple myeloma were randomly assigned to receive KRd or Rd. The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 and myeloma-specific module were administered at baseline; day 1 of cycles 3, 6, 12, and 18; and after treatment. The Global Health Status/Quality of Life (GHS/QoL) scale and seven subscales (fatigue, nausea and vomiting, pain, physical functioning, role functioning, disease symptoms, and adverse effects of treatment) were compared between groups using a mixed model for repeated measures. The percentages of responders with ≥ 5- or 15-point GHS/QoL improvement at each cycle were compared between groups. Results Baseline questionnaire compliance was excellent (94.1% of randomly assigned patients). KRd patients had higher GHS/QoL scores versus Rd patients over 18 treatment cycles (two-sided P < .001). The minimal important difference was met at cycle 12 (5.6 points) and approached at cycle 18 (4.8 points). There was no difference between groups for the other prespecified subscales from ASPIRE. A higher proportion of KRd patients met the GHS/QoL responder definition (≥ 5-point improvement) with statistical differences at cycle 12 (KRd v Rd patients, 25.5% v 17.4%, respectively) and 18 (KRd v Rd patients, 24.2% v 12.9%, respectively). Conclusion KRd improves GHS/QoL without negatively affecting patient-reported symptoms when compared with Rd. These data further support the benefit of KRd in patients with relapsed multiple myeloma.

    Carbapenem antibiotics are considered the treatment of choice for serious extended-spectrum beta-lactamase (ESBL)-producing Gram-negative bacteria (GNB) infections. The study objectives were to evaluate efficacy and safety of de-escalation therapy to ertapenem for treatment of infections caused by extended-spectrum-β-lactamase-producing Enterobacteriaceae. We conducted a randomized controlled trial of adult patients with documented ESBL-producing Enterobacteriaceae infections who had received any group 2 carbapenem for less than 96 h. In the intervention group, the previously-prescribed group 2 carbapenem was de-escalated to ertapenem. In the control group, the group 2 carbapenem was continued. During June 2011-December 2014, 32 patients were randomized to the de-escalation group and 34 to the control group. Most common sites of infection were urinary tract infection (42%). Characteristics of both groups were comparable. By using a 15% predefined margin, ertapenem was non-inferior to control group regarding the clinical cure rate (%Δ = 14.0 [95% confidence interval: -2.4 to 31.1]), the microbiological eradication rate (%Δ = 4.1 [-5.0 to 13.4]), and the superimposed infection rate (%Δ = -16.5 [-38.4 to 5.3]). Patients in the de-escalation group had a significantly lower 28-day mortality rate (9.4% vs. 29.4%; P = .05), a significantly shorter median length of stay (16.5 days [4.0-73.25] vs. 20.0 days [1.0-112.25]; P = .04), and a significantly lower defined daily dose of carbapenem use (12.9 ± 8.9 vs. 18.4 ± 12.6; P = .05). Ertapenem could be safely used as de-escalation therapy for ESBL-producing Enterobacteriaceae infections, once the susceptibility profiles are known. Future studies are needed to investigate ertapenem efficacy against ESBL-producing Enterobacteriaceae pneumonia to determine its applicability in life-threatening conditions.

    There is increasing evidence demonstrating the value of transfusions in sickle cell disease (SCD). However, resultant iron overload can be life threatening if untreated. Chelation therapy with deferoxamine requires parenteral infusions that can negatively impact quality of life and adherence to treatment. As part of a phase II trial, SCD patient-reported outcomes were evaluated. One hundred and ninety-five patients were randomized (2:1) to receive oral deferasirox (5-30 mg/kg/day) or deferoxamine (20-50 mg/kg, 5 days per week); 121 had previously received deferoxamine. At each time point, significantly more patients who had previously received deferoxamine were 'satisfied/very satisfied' with deferasirox, or found treatment to be 'convenient/very convenient' compared with deferoxamine (p < 0.001). In these patients, fewer hours were lost from daily activities with deferasirox than deferoxamine treatment. Most patients (77%) preferred deferasirox, and more were willing to continue taking deferasirox than deferoxamine at end-of-study (84 vs. 11%, respectively). Patients with SCD are therefore more satisfied with deferasirox, which has a lower impact on daily activities than deferoxamine. Given the high levels of satisfaction, it is likely that quality of life will be improved. These results also suggest that treatment adherence with deferasirox may be better than with deferoxamine, which should lead to improved long-term outcomes. 2008 S. Karger AG, Basel.

    Anogenital warts are caused by human papillomavirus (HPV), over 30 types of which are infectious for the anogenital tract. Without treatment, warts may regress spontaneously, remain unchanged, or increase in number and size. This study compared the efficacy of a topical 5% potassium hydroxide (KOH) solution with that of a topical 0.5% 5-fluorouracil (5-FU) and 10% salicylic acid (SA) combination in the treatment of anogenital warts. Sixty patients were randomly assigned to receive topical KOH or 5-FU + SA. Both groups demonstrated a significant decrease in numbers of lesions (P  0.05). The mean number of lesions decreased from baseline to week 12 from 17.03 ± 12.64 to 3.73 ± 7.30 and from 16.13 ± 12.97 to 3.10 ± 4.90 in the KOH and 5-FU + SA groups, respectively (P  0.05). No serious adverse events were reported. Neither treatment was more efficacious. Safety and ease of application are important goals in treatments for anogenital warts. A 5% KOH solution is a promising alternative treatment because it is effective and inexpensive and causes minimal side effects. © 2014 The International Society of Dermatology.

    Full Text Available Background. Aprepitant is a P/neurokinin-1 receptor antagonist approved for the prevention of CINV in moderate emetic risk chemotherapy. We explored its effectiveness in patients with leukemia receiving cytarabine-based chemotherapy. Methods. Patients were randomized to ondansetron (OND 8 mg IV 30 minutes before cytarabine followed by 24 mg IV continuous infusion daily until 6–12 hours after the last dose of chemotherapy alone or with aprepitant (APREP oral 125 mg 6–12 hrs before chemotherapy and 80 mg daily until 1 day after the last dose of chemotherapy. Results. Forty-nine patients were enrolled in each arm; 42 in OND and 41 in OND + APREP arm were evaluable for efficacy. The ORR with OND + APREP was 80% compared to 67% with OND alone (P=0.11. On days 6 and 7, higher proportion of patients treated with OND + APREP were free from nausea (74%, 74% versus 68%, 67%; P=0.27 and 0.18, resp.. Requirement of rescue medications on days 2 and 3 was fewer in OND + APREP arm 7% and 5% compared to 21% and 16% in the OND arm, respectively (P=0.06 and P=0.07. Conclusions. There was a trend for overall improvement in emesis with ondansetron plus aprepitant. The potential benefit of this approach with specific chemotherapy combinations remains to be determined.

    Upper respiratory tract infections are the most common causes of medical visits in children and adults, demanding massive use of antibiotics. Bacterial resistance caused by beta-lactamase is one of the most serious problems in this matter. Sultamicillin, a double pro-drug of Ampicillin/Sulbactan, is a potent beta-lactamase inhibitor which can face this challenge. Evaluate efficacy, safety and tolerability of Ampicillin/Sulbactan compared to Amoxicillin/Clavulanate in upper respiratory tract infections in adults. 102 patients were enrolled and randomized to receive Ampicillin/Sulbactan or Amoxicillin/Clavulanate during 10 days. They were evaluated 10 and 30 days after treatment to learn about the therapeutic response. There were no differences between the two groups respecting cure at the end of treatment (visit 2) or at the end of the study (visit 3). Cure ratio was 61.7% and 93.2% (visits 2 and 3) in the Amoxicillin/Clavulanate group compared to 64.4% and 97.4%, respectively, in Ampicillin/Sulbactan group. The adverse events ratio for the two groups was the same (p=0.940). The number of patients with diarrhea was greater in the group of patients receiving Amoxicillin/Clavulanate (70.6%) than in the group receiving Ampicillin/Sulbactan (29.4%) (p=0.0164). Ampicillin/Sulbactan is as safe and efficient as Amoxicillin/Clavulanate in the empiric treatment of upper respiratory infections in adults. The low occurrence of diarrhea in the group receiving Ampicillin/Sulbactan needs confirmation in other studies.

    Purpose Nivolumab, a programmed death-1 inhibitor, prolonged overall survival compared with docetaxel in two independent phase III studies in previously treated patients with advanced squamous (CheckMate 017; ClinicalTrials.gov identifier: NCT01642004) or nonsquamous (CheckMate 057; ClinicalTrials.gov identifier: NCT01673867) non-small-cell lung cancer (NSCLC). We report updated results, including a pooled analysis of the two studies. Methods Patients with stage IIIB/IV squamous (N = 272) or nonsquamous (N = 582) NSCLC and disease progression during or after prior platinum-based chemotherapy were randomly assigned 1:1 to nivolumab (3 mg/kg every 2 weeks) or docetaxel (75 mg/m 2 every 3 weeks). Minimum follow-up for survival was 24.2 months. Results Two-year overall survival rates with nivolumab versus docetaxel were 23% (95% CI, 16% to 30%) versus 8% (95% CI, 4% to 13%) in squamous NSCLC and 29% (95% CI, 24% to 34%) versus 16% (95% CI, 12% to 20%) in nonsquamous NSCLC; relative reductions in the risk of death with nivolumab versus docetaxel remained similar to those reported in the primary analyses. Durable responses were observed with nivolumab; 10 (37%) of 27 confirmed responders with squamous NSCLC and 19 (34%) of 56 with nonsquamous NSCLC had ongoing responses after 2 years' minimum follow-up. No patient in either docetaxel group had an ongoing response. In the pooled analysis, the relative reduction in the risk of death with nivolumab versus docetaxel was 28% (hazard ratio, 0.72; 95% CI, 0.62 to 0.84), and rates of treatment-related adverse events were lower with nivolumab than with docetaxel (any grade, 68% v 88%; grade 3 to 4, 10% v 55%). Conclusion Nivolumab provides long-term clinical benefit and a favorable tolerability profile compared with docetaxel in previously treated patients with advanced NSCLC.

    The highest risk for invasive meningococcal disease (IMD) is in infants aged CRM, a quadrivalent meningococcal conjugate vaccine, concomitantly administered with routine vaccinations to healthy infants. Two-month-old infants were randomized 3:1 to receive MenACWY-CRM with routine vaccines or routine vaccines alone at ages 2, 4, 6 and 12 months. Adverse events (AEs) that were medically attended and serious adverse events (SAEs) were collected from all subjects from enrollment through 18 months of age. In a subset, detailed safety data (local and systemic solicited reactions and all AEs) were collected for 7 days post vaccination. The primary objective was a non-inferiority comparison of the percentages of subjects with ≥1 severe systemic reaction during Days 1-7 after any vaccination of MenACWY-CRM plus routine vaccinations versus routine vaccinations alone (criterion: upper limit of 95% confidence interval [CI] of group difference CRM plus routine vaccines and 13% after routine vaccines alone (group difference 3.0% (95% CI -0.8, 6.4%). Although the non-inferiority criterion was not met, post hoc analysis controlling for significant center and group-by-center differences revealed that MenACWY-CRM plus routine vaccinations was non-inferior to routine vaccinations alone (group difference -0.1% [95% CI -4.9%, 4.7%]). Rates of solicited AEs, medically attended AEs, and SAEs were similar across groups. In a large multinational safety study, a 4-dose series of MenACWY-CRM concomitantly administered with routine vaccines was clinically acceptable with a similar safety profile to routine vaccines given alone.

    Evaluate systemic exposure with repeated topical application of a fixed-combination topical gel product containing 1% diclofenac sodium and 3% menthol in either of 2 formulation packages relative to oral administration. In this phase 1, single-center, 4-way crossover study, healthy volunteers aged 18 - 50 years underwent consecutive 3-day treatment regimens in a randomly assigned sequence with each of 4 treatment groups: 4 g of topical 1% diclofenac + 3% menthol gel administered via an aluminum tube or roll-on device applied 4 times daily; 4 g of topical 1% diclofenac sodium gel (Voltaren Gel) applied 4 times daily; and oral diclofenac sodium tablets 50 mg 3 times daily. Treatment regimens were separated by 2-day washout periods. A total of 18 subjects enrolled and completed the study. Relative to oral administration, area under the concentration time curve from 48 to 72 hours (AUC48-72) with topical administration of 1% diclofenac + 3% menthol gel from a tube or roll-on device was 16.1% (90% CI: 12.2 - 21.1%) and 14.4% (90% CI: 11.0 - 19.0%), respectively. The diclofenac/menthol combination delivered significantly higher exposures of diclofenac compared with Voltaren Gel. A higher number of adverse events (AEs) occurred with the topical diclofenac/menthol combination (61%) vs. Voltaren Gel (22%) or oral diclofenac (6%); most were local skin reactions. No difference in systemic AEs was observed among the groups. As expected, systemic exposure was significantly lower with the topical diclofenac/menthol treatment regimens compared with oral diclofenac. Local skin AEs were increased with the topical combination product, but the risk of systemic AEs was low.

    To evaluate the efficacy and safety of a combination therapy with dutasteride and imidafenacin in patients with benign prostatic hyperplasia and persistent overactive bladder symptoms. A total of 163 patients presenting an enlarged prostate (volume >30 mL) and persistent overactive bladder symptoms despite at least 8 weeks of tamsulosin were randomized to receive tamsulosin and dutasteride, or tamsulosin, dutasteride and imidafenacin at a 1:1 ratio. The primary end-point was the mean change from baseline to week 24 in total overactive bladder symptom score. The mean change in total overactive bladder symptom score from baseline at week 24 was -1.99 (95% confidence interval -2.57 to -1.41) in the tamsulosin and dutasteride group, and -3.12 (95% confidence interval -3.72 to -2.52) in the tamsulosin, dutasteride and imidafenacin group. The tamsulosin, dutasteride and imidafenacin group significantly improved total overactive bladder symptom score at week 24 as compared with the tamsulosin and dutasteride group; the mean difference was -1.18 (-2.02 to -0.34). The between-group difference was statistically significant as early as week 4. The total International Prostate Symptom Score, storage subscore, quality of life index, and benign prostatic hyperplasia impact index also significantly improved in the tamsulosin, dutasteride and imidafenacin group. Tamsulosin, dutasteride and imidafenacin combination therapy improves overactive bladder symptoms and quality of life without causing serious adverse drug reactions in patients with enlarged prostate not responding to tamsulosin. This combination therapy seems to represent a promising therapeutic option in these patients. © 2017 The Japanese Urological Association.

    Genexol-PM is a Cremophor EL-free formulation of low-molecular-weight, non-toxic, and biodegradable polymeric micelle-bound paclitaxel. We conducted a phase III study comparing the clinical efficacy and toxicity of Genexol-PM with conventional paclitaxel (Genexol). Patients were randomly assigned (1:1) to receive Genexol-PM 260 mg/m 2 or Genexol 175 mg/m 2 intravenously every 3 weeks. The primary outcome was the objective response rate (ORR). The study enrolled 212 patients, of whom 105 were allocated to receive Genexol-PM. The mean received dose intensity of Genexol-PM was 246.8±21.3 mg/m 2 (95.0%), and that of Genexol was 168.3±10.6 mg/m 2 (96.2%). After a median follow-up of 24.5 months (range, 0.0 to 48.7 months), the ORR of Genexol-PM was 39.1% (95% confidence interval [CI], 31.2 to 46.9) and the ORR of Genexol was 24.3% (95% CI, 17.5 to 31.1) (p non-inferiority =0.021, p superiority =0.016). The two groups did not differ significantly in overall survival (28.8 months for Genexol-PM vs. 23.8 months for Genexol; p=0.52) or progression-free survival (8.0 months for Genexol-PM vs. 6.7 months for Genexol; p=0.26). In both groups, the most common toxicities were neutropenia, with 68.6% occurrence in the Genexol-PM group versus 40.2% in the Genexol group (p cancer.

    Diabetes mellitus type 2 (DMT2) and non-alcoholic fatty liver disease (NAFLD) are both characterized by decreased circulating adiponectin. Recently, glucagon-like peptide-1 receptor agonists have been shown to induce adiponectin's expression. However, their interaction on clinical grounds needs to be further elucidated. DMT2 patients with abnormal aminotransferases were screened for NAFLD and subjected to liver biopsy (group A, n=17). A subgroup of patients (n=110), after assessed for eligibility criteria, was blindly randomized to receive either 6-month exenatide supplementation on glargine insulin (group B) or intense, self-regulated, insulin therapy alone (group C). Baseline patient characteristics: 49(38.6%) males, aged 63.1 ± 7.5 years-old, BMI 32.9 ± 4.9 kg/m(2), HbA1c 8.1 ± 1.2% (65 ± 14 mmol/mol), median ALT 23 U/L (range 5-126), AST 20 U/L (7-72). Group A had biopsy-proven NAFLD with a median Activity Score of 5 and fibrosis stage 3. Presence of NAFLD was accompanied by a significant decline in adiponectin (p<0.001), which was negatively correlated with the degree of ALT in all groups (Spearman's correlation, rs=-0.644, p<0.001). In the subgroup intervention trial, adiponectin was significantly raised in both groups B and C (t-Student for paired samples, p=0.001) by Δ=+24.2% (interquartile range 14.8-53.2%). This elevation was not associated with the type of intervention but with weight loss, glycemic control and reduction of C-reactive protein (one-way ANCOVA). Supplementation of exenatide to glargine insulin compared to standard insulin was: (i) effective in inducing weight loss, (ii) non-inferior in lowering HbA1c and (iii) non-inferior in increasing circulating adiponectin. Higher adiponectin was associated with lower ALT, suggesting a hepato-protective role for this cytokine. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    During the influenza pandemic 2009-2010, an AS03-adjuvanted A(H1N1)pdm09 vaccine was used extensively in children 6 months of age and older, and during the 2010-2011 influenza season, the A(H1N1)pdm09 strain was included in the seasonal trivalent inactivated influenza vaccine (TIV) without adjuvant. We evaluated the immunogenicity and safety of TIV in children previously vaccinated with the AS03-adjuvanted A(H1N1)pdm09 vaccine. Healthy children were randomized (1:1) to receive TIV or a control vaccine. Children were aged 6 months to 9 years (n = 154) and adolescents 10-17 years (n = 77) when they received AS03-adjuvanted A(H1N1)pdm09 vaccine at least 6 months before study enrolment. Hemagglutination inhibition (HI) and neutralizing antibody responses against the A(H1N1)pdm09 strain were evaluated before (day 0) and at day 28 and month 6 after study vaccination. Reactogenicity was assessed during the 7 day postvaccination period, and safety was assessed for 6 months. At day 0, >93.9% of all children had HI titers ≥1:40 for the A(H1N1)pdm09 strain, which increased to 100% at both day 28 and month 6 in the TIV group. Between days 0 and 28, HI antibody geometric mean titers against A(H1N1)pdm09 increased by 9-fold and 4-fold in children 6 months to 9 years of age and 10-17 years of age, respectively. AS03-adjuvanted A(H1N1)pdm09 vaccine-induced robust immune responses in children that persisted into the next season, yet were still boosted by TIV containing A(H1N1)pdm09. The reactogenicity and safety profile of TIV did not appear compromised by prior receipt of AS03-adjuvanted A(H1N1)pdm09 vaccine.

    Purpose Reduction of adjuvant treatment duration may decrease toxicities without loss of efficacy in stage III colon cancer. This could offer clear advantages to patients and health care providers. Methods In International Duration Evaluation of Adjuvant Chemotherapy (IDEA) France, as part of the IDEA international collaboration, patient with colon cancer patients were randomly assigned to 3 and 6 months of modified FOLFOX6 (mFOLFOX6: infusional fluorouracil, leucovorin, and oxaliplatin) or capecitabine plus oxaliplatin (CAPOX) by physician choice. The primary end point was disease-free survival (DFS), and analyses were descriptive. Results A total of 2,010 eligible patients received either 3 or 6 months of chemotherapy (modified intention-to-treat population); 2,000 (99%) had stage III colon cancer (N1: 75%, N2: 25%); 1,809 (90%) received mFOLFOX6, and 201 (10%) received CAPOX. The median age was 64 years, and the median follow-up time was 4.3 years. Overall, 94% (3 months) and 78% (6 months) of patients completed treatment (fluoropyrimidines ± oxaliplatin). Maximal grade 2 and 3 neuropathy rates were 28% and 8% in the 3-month arm and 41% and 25% in the 6-month arm ( P < .001). Final rates of residual neuropathy greater than grade 1 were 3% in the 3-month arm and 7% in the 6-month arm ( P < .001). There were 578 DFS events: 314 and 264 in the 3- and 6-month arms, respectively. The 3-year DFS rates were 72% and 76% in the 3- and 6-month arms, respectively (hazard ratio [HR], 1.24; 95% CI, 1.05 to 1.46; P = .0112). In the 3 and 6-month arms, respectively, for patients who received mFOLFOX6, the 3-year DFS rates were 72% and 76% (HR, 1.27; 95% CI, 1.07 to 1.51); for the T4 and/or N2 population, they were 58% and 66% (HR, 1.44; 95% CI, 1.14 to 1.82); and for the T1-3N1 population, they were 81% and 83% (HR, 1.15; 95% CI, 0.89 to 1.49). Conclusion IDEA France, in which 90% of patients received mFOLFOX6, shows superiority of 6 months of adjuvant chemotherapy compared

    The study aimed to assess the pharmacokinetics of a new, modified-release metoclopramide tablet, and compare it to an immediate-release tablet. A single and multiple-dose, randomized, open-label, parallel, pharmacokinetic study was conducted. Investigational products were administered to 26 healthy Hispanic Mexican male volunteers for two consecutive days: either one 30 mg modified-release tablet every 24 h, or one 10 mg immediate-release tablet every 8 h. Blood samples were collected after the first and last doses of metoclopramide. Plasma metoclopramide concentrations were determined by high-performance liquid chromatography. Safety and tolerability were assessed through vital signs measurements, clinical evaluations, and spontaneous reports from study subjects. All 26 subjects were included in the analyses [mean (SD) age: 27 (8) years, range 18-50; BMI: 23.65 (2.22) kg/m², range 18.01-27.47)]. Peak plasmatic concentrations were not statistically different with both formulations, but occurred significantly later (p 0.05)]. One adverse event was reported in the test group (diarrhea), and one in the reference group (headache). This study suggests that the 30 mg modified-release metoclopramide tablets show features compatible with slow-release formulations when compared to immediate-release tablets, and is suitable for once-a-day administration.

    The present study was to compare the efficacy and safety of subject-driven and investigator-driven titration of biphasic insulin aspart 30 (BIAsp 30) twice daily (BID). In this 20-week, randomized, open-label, two-group parallel, multicenter trial, Chinese patients with type 2 diabetes inadequately controlled by premixed/self-mixed human insulin were randomized 1:1 to subject-driven or investigator-driven titration of BIAsp 30 BID, in combination with metformin and/or α-glucosidase inhibitors. Dose adjustment was decided by patients in the subject-driven group after training, and by investigators in the investigator-driven group. Eligible adults (n = 344) were randomized in the study. The estimated glycated hemoglobin (HbA1c) reduction was 14.5 mmol/mol (1.33%) in the subject-driven group and 14.3 mmol/mol (1.31%) in the investigator-driven group. Non-inferiority of subject-titration vs investigator-titration in reducing HbA1c was confirmed, with estimated treatment difference -0.26 mmol/mol (95% confidence interval -2.05, 1.53) (-0.02%, 95% confidence interval -0.19, 0.14). Fasting plasma glucose, postprandial glucose increment and self-measured plasma glucose were improved in both groups without statistically significant differences. One severe hypoglycemic event was experienced by one subject in each group. A similar rate of nocturnal hypoglycemia (events/patient-year) was reported in the subject-driven (1.10) and investigator-driven (1.32) groups. There were 64.5 and 58.1% patients achieving HbA1c titration of BIAsp 30 BID was as efficacious and well-tolerated as investigator-titration. The present study supported patients to self-titrate BIAsp 30 BID under physicians' supervision.

    The aim of this Phase IIIb, open-label, randomized study was to demonstrate the non-inferiority of immune responses and to assess the safety of a purified chick-embryo cell rabies vaccine (PCECV) in healthy Chinese children (6 to 17 years) and older adults (≥51 years) following 2 alternative intramuscular (IM) simulated post-exposure prophylaxis (PEP) regimens: 4-dose Zagreb or 5-dose Essen regimen. Serum samples were collected prior to vaccination on Days 1 and 15 and on day 43 to assess immune response by rabies virus neutralizing antibody (RVNA) concentrations. Solicited adverse events (AEs) were recorded for up to 7 days following each vaccine dose, and unsolicited AEs throughout the entire study period. PCECV vaccination induced a strong immune response at Day 15, and the non-inferiority in immune response of the Zagreb vs. the Essen regimen was demonstrated in children and older adults. At Day 15,100% of children (N = 224), and 99% of subjects ≥51 years of age (N = 376) developed adequate RVNA concentrations (≥0.5 IU/mL); at Day 43 all subjects achieved RVNA concentrations ≥0.5 IU/mL, for both PEP regimens. The well-known tolerability and safety profile of the PCECV was again observed in this study following either Zagreb or Essen regimens. Rabies PEP vaccination with PCECV following a Zagreb regimen induced immune responses non-inferior to those of the Essen regimen, and had a similar safety and tolerability profile to the Essen regimen in Chinese children, adolescents, and adults over 51 years.

    The World Health Organization (WHO) recommends viral load (VL) measurement as the preferred monitoring strategy for HIV-infected individuals on antiretroviral therapy (ART) in resource-limited settings. The new WHO guidelines 2016 continue to define virologic failure as two consecutive VL ≥1000 copies/mL (at least 3 months apart) despite good adherence, triggering switch to second-line therapy. However, the threshold of 1000 copies/mL for defining virologic failure is based on low-quality evidence. Observational studies have shown that individuals with low-level viremia (measurable but below 1000 copies/mL) are at increased risk for accumulation of resistance mutations and subsequent virologic failure. The SESOTHO trial assesses a lower threshold for switch to second-line ART in patients with sustained unsuppressed VL. In this multicenter, parallel-group, open-label, randomized controlled trial conducted in Lesotho, patients on first-line ART with two consecutive unsuppressed VL measurements ≥100 copies/mL, where the second VL is between 100 and 999 copies/mL, will either be switched to second-line ART immediately (intervention group) or not be switched (standard of care, according to WHO guidelines). The primary endpoint is viral resuppression (VL < 50 copies/mL) 9 months after randomization. We will enrol 80 patients, giving us 90% power to detect a difference of 35% in viral resuppression between the groups (assuming two-sided 5% alpha error). For our primary analysis, we will use a modified intention-to-treat set, with those lost to care, death, or crossed over considered failure to resuppress, and using logistic regression models adjusted for the prespecified stratification variables. The SESOTHO trial challenges the current WHO guidelines, assessing an alternative, lower VL threshold for patients with unsuppressed VL on first-line ART. This trial will provide data to inform future WHO guidelines on VL thresholds to recommend switch to second-line ART

The main outcome measures were: 1) tremor clinical rating scale (TCRS) score, 2) accelerometric recordings, and 3) self-reported disability scale score. Results Five patients completed the study, and two dropped out due to adverse effects. There were no significant changes in clinical scores in motor task performance (TCRS 1+2), daily living activities (TCRS 3), or in the patients’ subjective assessment (TCRS 4) and global appraisal. There were no differences observed for accelerometry data or disability scale scores. Anxiety, nervousness, headache, and dizziness were reported by two patients while on ethosuximide, causing them to stop the trial. No patient preferred to continue ethosuximide treatment.

    Spasmodic dysphonia (SD) is a task-specific laryngeal dystonia that affects speech production. Co-occurring voice tremor (VT) often complicates the diagnosis and clinical management of SD. Treatment of SD and VT is largely limited to botulinum toxin injections into laryngeal musculature; other pharmacological options are not sufficiently developed. Open-label study. We conducted an open-label study in 23 SD and 22 SD/VT patients to examine the effects of sodium oxybate (Xyrem), an oral agent with therapeutic effects similar to those of alcohol in these patients. Blinded randomized analysis of voice and speech samples assessed symptom improvement before and after drug administration. Sodium oxybate significantly improved voice symptoms (P = .001) primarily by reducing the number of SD-characteristic voice breaks and severity of VT. Sodium oxybate further showed a trend for improving VT symptoms (P = .03) in a subset of patients who received successful botulinum toxin injections for the management of their SD symptoms. The drug's effects were observed approximately 30 to 40 minutes after its intake and lasted about 3.5 to 4 hours. Our study demonstrated that sodium oxybate reduced voice symptoms in 82.2% of alcohol-responsive SD patients both with and without co-occurring VT. Our findings suggest that the therapeutic mechanism of sodium oxybate in SD and SD/VT may be linked to that of alcohol, and as such, sodium oxybate might be beneficial for alcohol-responsive SD and SD/VT patients. 4 Laryngoscope, 127:1402-1407, 2017. © 2016 The American Laryngological, Rhinological and Otological Society, Inc.

  15.

    Morphine sulfate/sequestered naltrexone hydrochloride (HCl) (MS-sNT) extended-release fixed-dose combination capsules, approved by the US Food and Drug Administration (FDA) in August 2009 for chronic moderate to severe pain, contain extended-release morphine pellets with a sequestered core of the opioid antagonist naltrexone. MS-sNT was designed so that if the product is tampered with by crushing, the naltrexone becomes bioavailable to mitigate morphine-induced subjective effects, rendering the product less attractive for tampering. The primary aim of this study was to compare the oral bioavailability of naltrexone and its metabolite 6-beta-naltrexol, derived from crushed pellets from MS-sNT capsules, to naltrexone solution. This study also assessed the relative bioavailability of morphine from crushed pellets from MS-sNT capsules and that from the whole, intact product. This single-dose, randomized-sequence, open-label, 3-period, 3-treatment crossover trial was conducted in healthy volunteers. Adults admitted to the study center underwent a 10-hour overnight fast before study drug administration. Each subject received all 3 of the following treatments, 1 per session, separated by a 14-day washout: tampered pellets (crushed for >or=2 minutes with a mortar and pestle) from a 60-mg MS-sNT capsule (60 mg morphine/2.4 mg naltrexone); 60-mg whole, intact MS-sNT capsule; and oral naltrexone HCl (2.4 mg) solution. Plasma concentrations of naltrexone and 6-beta-naltrexol were measured 0 to 168 hours after administration. Morphine pharmaco-kinetics of crushed and whole pellets were determined 0 to 72 hours after administration. The analysis of relative bioavailability was based on conventional FDA criteria for assuming bioequivalence; that is, 90% CIs for ratios of geometric means (natural logarithm [In]-transformed C(max) and AUC) fell within the range of 80% to 125%. Subjects underwent physical examinations, clinical laboratory tests, and ECG at screening and study

    While many of the commonly used treatments for perioperative pain after total knee arthroplasty (TKA) have been recognized as effective, there is still insufficient evidence for oral medication. In orthopedics, non-steroidal anti-inflammatory drugs (NSAIDs) have been commonly used for perioperative pain; however, serious adverse events have been reported. Conversely, tramadol hydrochloride/acetaminophen combination (TRAM/APAP) therapy has been shown to reduce pain, particularly for chronic pain in Japan. This study aimed to determine TRAM/APAP efficacy in comparison with NSAIDs for perioperative pain after TKA. Two hundred eighty patients were enrolled in this study; 137 patients were treated with TRAM/APAP, and 143 patients were treated with NSAID from postoperative (PO) day 2. The primary endpoint was a comparison between the pain visual analog scale (VAS) change from baseline (PO day 2) and PO day 4, day 7, day 10, and day 14. The second endpoint was the number of days until the patient achieved independence from cane walking. Analysis of endpoints included 130 and 139 patients in the TRAM/APAP and NSAID groups, respectively. The pain VAS change in the TRAM/APAP group on any of the measurement days was significantly improved compared with the NSAID group (P pain management after TKA of TRAM/APAP was shown to be superior to that of NSAID; TRAM/APAP was also effective in improving the progress of rehabilitation.

Women (aged 40-65 y) experiencing menopause-related fatigue received open-label armodafinil therapy (up to 150 mg/d) for 4 weeks. Changes from baseline in Brief Fatigue Inventory score and Menopause-Specific Quality of Life (MENQOL) physical domain score were examined using the Wilcoxon signed rank test. Exploratory analyses examined the effects of armodafinil on hot flashes, overall quality of life, insomnia, depression, anxiety, and perceived cognitive performance. After open-label treatment, participants were randomized to double-blind continuation of armodafinil versus placebo for 2 weeks to examine whether treatment discontinuation would precipitate symptom recurrence. Of 29 eligible participants, 20 women (69.0%) completed the trial. During treatment with armodafinil (mean dose, 120 mg/d), median Brief Fatigue Inventory scores decreased by 57.7% from 5.2 (interquartile range [IQR], 4.6-6.2) to 2.2 (IQR, 1.1-4.4; P = 0.0002), and median MENQOL physical domain scores decreased by 51.3% from 3.9 (IQR, 2.3-4.8) to 1.9 (IQR, 1.3-2.7; P = 0.0001). Median hot flashes for 24 hours decreased by 48.3% from 2.9 (IQR, 1.1-4.6) to 1.5 (IQR, 0.4-2.4; P = 0.0005). Improvements in MENQOL total score (49%; P = 0.0001), cognitive function (59.2%; P = 0.0002), depressive symptoms (64.7%; P = 0.0006), insomnia (72.7%; P = 0.0012), and excessive sleepiness (57.1%; P = 0.0006) were noted. Randomized continuation (n = 10) or discontinuation (n = 10) did not indicate group differences. Armodafinil was well-tolerated; three women (12%) were withdrawn for adverse events. These preliminary results suggest a therapeutic effect of armodafinil on fatigue affecting quality of life during menopause, and a potential benefit for other menopause-related symptoms.

    Our objective was to assess the therapeutic noninferiority of dual therapy with darunavir/ritonavir and lamivudine compared to triple therapy with darunavir/ritonavir plus 2 nucleos(t)ides for maintenance of human immunodeficiency virus type 1 (HIV-1) suppression. This was a multicenter, open-label, noninferiority trial (margin 12%). Patients with HIV-1 RNA dual- and triple-therapy arms was 88.9% (112/126) and 92.7% (114/123; difference, -3.8%; 95% confidence interval, -11.0 to 3.4), respectively. Four participants in the dual-therapy arm and 2 in the triple-therapy arm developed protocol-defined virological failure. Switching to dual therapy was associated with a significant increase in total, low-density lipoprotein, and high-density lipoprotein (HDL) cholesterol, but not in the total-to-HDL cholesterol ratio. Serious adverse events and study drug discontinuations due to adverse events occurred in 4.8% vs 4.9%P = .97) and in 0.8% (1/126) vs 1.6% P = .55) in dual therapy vs triple therapy, respectively. Dual therapy with darunavir/ritonavir and lamivudine demonstrated noninferior therapeutic efficacy and similar tolerability compared to triple therapy. NCT02159599. © The Author 2017.

    The long-term safety and therapeutic response of sodium oxybate (SXB) in fibromyalgia syndrome (FM) patients were assessed for a combined period of up to 1 year in a prospective, multicenter, open-label, extension study in patients completing 1 of 2 phase 3 randomized, double-blind, controlled, 14-week trials that examined the efficacy and safety of SXB 4.5 g, SXB 6 g, and placebo for treatment of FM. This extension study comprised an additional 38 weeks of treatment and was carried out at 130 clinical sites in 7 countries. Initial entry criteria for the previous 2 double-blind clinical trials required that patients aged ≥ 18 years met the American College of Rheumatology 1990 criteria for FM, had a body mass index (BMI) Fibromyalgia Impact Questionnaire (FIQ) total scores, and other measures. Responder analyses showed that 68.8% of patients achieved ≥ 30% reduction in pain VAS and 69.7% achieved ≥ 30% reduction in FIQ total score at study endpoint. The long-term safety profile of SXB in FM patients was similar to that in the previously reported controlled clinical trials. Improvement in pain and other FM clinical domains was maintained during long-term use. ClinicalTrials.gov NCT00423605.

    Fibromyalgia is a condition characterized by widespread chronic pain. Due to the high prevalence and high costs, it has a substantial burden on society. Treatment results are diverse and only help a small subset of patients. C2 nerve field stimulation, aka occipital nerve stimulation, is helpful and a minimally invasive treatment for primary headache syndromes. Small C2 pilot studies seem to be beneficial in fibromyalgia. Forty patients were implanted with a subcutaneous electrode in the C2 dermatoma as part of a prospective, double-blind, randomized, controlled cross-over study followed by an open label follow up period of 6 months. The patients underwent 2 week periods of different doses of stimulation consisting of minimal (.1 mA), subthreshold, and suprathreshold (for paresthesias) in a randomized order. Twenty seven patients received a permanent implant and 25 completed the 6 month open label follow up period. During the 6 week trial phase of the study, patients had an overall decrease of 36% on the fibromyalgia impact questionnaire (FIQ), a decrease of 33% fibromyalgia pain and improvement of 42% on the impact on daily life activities and quality. These results imply an overall improvement in the disease burden, maintained at 6 months follow up, as well as an improvement in life quality of 50%. Seventy six percent of patients were satisfied or very satisfied with their treatment. There seems to be a dose-response curve, with increasing amplitudes leading to better clinical outcomes. Subcutaneous C2 nerve field stimulation seems to offer a safe and effective treatment option for selected medically intractable patients with fibromyalgia. Copyright © 2015 Elsevier Inc.

    Full Text Available Background. Studies using standard neuropsychological instruments have demonstrated memory deficits in patients with PTSD. We evaluated the efficacy and safety of the N-methyl-D-aspartate antagonist memantine in veterans with PTSD and cognitive impairment. Methods. Twenty-six veterans with PTSD and cognitive impairment received 16 weeks of memantine in an open-label fashion. Cognition was assessed using the Spatial Span, Logical Memory I, and Letter-Number Sequencing subtests of the Wechsler Memory Scale III and the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS. RBANS measures attention, language, visuospatial skills, and immediate and delayed memories. The Clinician Administered PTSD Scale (CAPS, Hamilton Depression Scale (HAM-D, Hamilton Anxiety Scale (HAM-A, Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q, and Sheehan Disability Scale (SDS were secondary outcome measures. Results. There was a significant improvement in RBANS, both total and subscale scores (P<0.05, over time. There was a reduction in total CAPS scores, avoidance/numbing symptoms (CAPS-C and hyperarousal symptoms (CAPS-D, HAM-D, Q-LES-Q, and SDS scores. However, there was no reduction in reexperiencing (CAPS-B and HAM-A scores. Memantine was well tolerated. Conclusions. Memantine improved cognitive symptoms, PTSD symptoms, and mood in veterans with PTSD. Randomized double-blind studies are needed to validate these preliminary observations.

    Although the standard treatment of acute appendicitis (AA) consists of an early appendectomy, there has recently been both an interest and an increase in the use of antibiotic therapy as the primary treatment for uncomplicated AA. However, the use of antibiotic therapy in the treatment of uncomplicated AA is still controversial. The APPAC trial is a randomized prospective controlled, open label, non-inferiority multicenter trial designed to compare antibiotic therapy (ertapenem) with emergency appendectomy in the treatment of uncomplicated AA. The primary endpoint of the study is the success of the randomized treatment. In the antibiotic treatment arm successful treatment is defined as being discharged from the hospital without the need for surgical intervention and no recurrent appendicitis during a minimum follow-up of one-year (treatment efficacy). Treatment efficacy in the operative treatment arm is defined as successful appendectomy evaluated to be 100%. Secondary endpoints are post-intervention complications, overall morbidity and mortality, the length of hospital stay and sick leave, treatment costs and pain scores (VAS, visual analoque scale). A maximum of 610 adult patients (aged 18-60 years) with a CT scan confirmed uncomplicated AA will be enrolled from six hospitals and randomized by a closed envelope method in a 1:1 ratio either to undergo emergency appendectomy or to receive ertapenem (1 g per day) for three days continued by oral levofloxacin (500 mg per day) plus metronidazole (1.5 g per day) for seven days. Follow-up by a telephone interview will be at 1 week, 2 months and 1, 3, 5 and 10 years; the primary and secondary endpoints of the trial will be evaluated at each time point. The APPAC trial aims to provide level I evidence to support the hypothesis that approximately 75-85% of patients with uncomplicated AA can be treated with effective antibiotic therapy avoiding unnecessary appendectomies and the related operative morbidity, also resulting

    Objective: In healthy women, there is a progressive age-related increase in myocardial mass that is not seen in their male counterparts and occurs primarily in postmenopausal women. Raloxifene is a selective estrogen receptor modulator that has estrogenic actions on bone and the cardiovascular system. The aim of this study was to investigate the effect of raloxifene on myocardial hypertrophy in postmenopausal patients. Methods: A total of 22 postmenopausal osteoporotic women were included in this open-label, randomized, prospective, controlled study. Patients were randomized into two groups: 11 of the patients (group 1) were treated with raloxifene 60 mg/day, and the other 11 patients (group 2) were defined as the control group. Quantitative 2-dimensional and M-mode echocardiographic examination was performed in all patients at the beginning and repeated at the end of the 6-month follow-up period. Left ventricle mass (LVM) and left ventricle mass index (LVMI) were calculated for all patients. Results: The mean age of the patients was 57.2±3.9 years, and baseline clinical characteristics and echocardiographic parameters were similar between the two groups. After 6 months of raloxifene treatment, there was no difference in echocardiographic parameters of LVM and LVMI compared with the control group (201.2±25.9 gr vs. 169.7±46.2 gr, p=0.14 and 120.4±25.9 gr/m2 vs. 105.5±26.3 gr/m2, p=0.195, respectively). There was also no significant difference in LVM and LVMI in the within-group analysis of both groups. Conclusion: Raloxifene therapy does not affect myocardial hypertrophy in postmenopausal women after 6 months of treatment. PMID:25430415

    2016-01-01

    Objective Spasmodic dysphonia (SD) is a task-specific laryngeal dystonia that affects speech production. Co-occurring voice tremor (VT) often complicates the diagnosis and clinical management of SD. Treatment of SD and VT is largely limited to botulinum toxin injections into laryngeal musculature; other pharmacological options are not sufficiently developed. Study Design and Methods We conducted an open-label study in 23 SD and 22 SD/VT patients to examine the effects of sodium oxybate (Xyrem®), an oral agent with therapeutic effects similar to those of alcohol in these patients. Blinded randomized analysis of voice and speech samples assessed symptom improvement before and after drug administration. Results Sodium oxybate significantly improved voice symptoms (p = 0.001) primarily by reducing the number of SD-characteristic voice breaks and severity of VT. Sodium oxybate further showed a trend for improving VT symptoms (p = 0.03) in a subset of patients who received successful botulinum toxin injections for the management of their SD symptoms. The drug’s effects were observed approximately 30–40 min after its intake and lasted about 3.5–4 hours. Conclusion Our study demonstrated that sodium oxybate reduced voice symptoms in 82.2% of alcohol-responsive SD patients both with and without co-occurring VT. Our findings suggest that the therapeutic mechanism of sodium oxybate in SD and SD/VT may be linked to that of alcohol and as such sodium oxybate might be beneficial for alcohol-responsive SD and SD/VT patients.

    Aims The primary objective was to explore the pharmacodynamic changes during transition from rivaroxaban to warfarin in healthy subjects. Safety, tolerability and pharmacokinetics were assessed as secondary objectives. Methods An open label, non-randomized, sequential two period study. In treatment period 1 (TP1), subjects received rivaroxaban 20 mg once daily (5 days), followed by co-administration with a warfarin loading dose regimen of 5 or 10 mg (for the 10 mg regimen, the dose could be uptitrated to attain target international normalized ratio [INR] ≥2.0) once daily (2–4 days). When trough INR values ≥2.0 were attained, rivaroxaban was discontinued and warfarin treatment continued as monotherapy (INR 2.0–3.0). During treatment period 2, subjects received the same warfarin regimen as in TP1, but without rivaroxaban. Results During co-administration, maximum INR and prothrombin time (PT) values were higher than with rivaroxaban or warfarin monotherapy. The mean maximum effect (Emax) for INR after co-administration was 2.79–4.15 (mean PT Emax 41.0–62.7 s), compared with 1.41–1.74 (mean PT Emax 20.1–25.2 s) for warfarin alone. However, rivaroxaban had the smallest effect on INR at trough rivaroxaban concentrations. Neither rivaroxaban nor warfarin significantly affected maximum plasma concentrations of the other drug. Conclusions The combined pharmacodynamic effects during co-administration of rivaroxaban and warfarin were greater than additive, but the pharmacokinetics of both drugs were unaffected. Co-administration was well tolerated. When transitioning from rivaroxaban to warfarin, INR monitoring during co-administration should be performed at the trough rivaroxaban concentration to minimize the effect of rivaroxaban on INR.

    Preeclampsia and intrauterine fetal growth restriction (IUGR) are two of the most common causes of maternal and perinatal morbidity and mortality. Current methods of predicting those at most risk of these conditions remain relatively poor, and in clinical practice past obstetric history remains the most commonly used tool. Aspirin and, in women at risk of preeclampsia only, calcium have been demonstrated to have a modest effect on risk reduction. Several observational studies and randomised trials suggest that low molecular weight heparin (LMWH) therapy may confer some benefit. This is a multicentre open label randomised controlled trial to determine the effect of the LMWH, enoxaparin, on the prevention of recurrence of preeclampsia and/or IUGR in women at high risk due to their past obstetric history in addition to standard high risk care for all participants. A singleton pregnancy >6 +0 and 12 weeks having; (1) preeclampsia delivered women are randomly assigned to 'standard high risk care' or 'standard high risk care' plus enoxaparin 40 mg from recruitment until 36 +0 weeks or delivery, whichever occurs sooner. Standard high risk care includes the use of aspirin 100 mg daily and calcium 1000-1500 mg daily (unless only had previous SGA with no preeclampsia). The primary outcome is preeclampsia and/or SGA restricted composite primary outcome. The inclusion of standard use of aspirin (and calcium) for all participants will help to ensure that any differences observed in outcome are likely to be related to enoxaparin use. These data will make a significant contribution to future meta-analyses and systematic reviews on the use of LMWH for the prevention of placental mediated conditions.

    Instantaneous wave-free ratio (iFR) is a new hemodynamic resting index for assessment of coronary artery stenosis severity. iFR uses high frequency sampling to calculate a gradient across a coronary lesion during a period of diastole. The index has been tested against fractional flow reserve (FFR) and found to have an overall classification agreement of 80% to 85%. Whether the level of disagreement is clinically relevant is unknown. Clinical outcome data on iFR are scarce. This study is a registry-based randomized clinical trial, which is a novel strategy using health quality registries as on-line platforms for randomization, case record forms, and follow-up. iFR-SWEDEHEART is a multicenter, prospective, randomized, controlled, clinical open-label clinical trial. Two thousand patients with stable angina or acute coronary syndrome and an indication for physiology-guided assessment of one or more coronary stenoses will be randomized 1:1 to either iFR- or FFR-guided intervention. The randomization will be conducted online in the Swedish web-based system for enhancement and development of evidence-based care in heart disease evaluated according to recommended therapies (SWEDEHEART) registry. The trial has a non-inferiority design, with a primary combined end point of all-cause death, non-fatal myocardial infarction, and unplanned revascularization at 12 months. End points will be identified through national registries and undergo central blind adjudication to ensure data quality. The iFR-SWEDEHEART trial is an registry-based randomized clinical trial evaluating the safety and efficacy of the diagnostic method iFR compared to FFR. Copyright © 2015 Elsevier Inc.

    To evaluate the effects of amnioinfusion in oligohydramniosis. During a 20-month period, patients at term with oligohydramniosis (amniotic fluid index less than 5 cm) at Huddinge University and Norrköping Hospitals were recruited for a prospective randomized study to evaluate amnioinfusion. Informed consent was obtained from 112 patients who met the entry criteria. Sixty subjects were randomized to amnioinfusion and 52 to the control group. Outcome parameters included fetal heart rate abnormalities, mode of delivery, Apgar score, pH in umbilical artery blood and need for neonatal intensive care. The cesarean section rate was significantly reduced in the amnio-infusion group (29% versus 13%, p=0.043). No difference in time from randomization to delivery was detected between the two groups. The frequency of ominous fetal heart rate tracings with a cervical dilatation of 0-3 cm was the same in the two groups. The frequency of such heart rate patterns after amnioinfusion was significantly lower than in the control group. Neonatal outcome, pH in the umbilical artery blood and need for neonatal intensive care did not differ between the two groups. The present study confirms the findings of other authors that amnioinfusion effectively reduces the number of cesarean sections in cases of oligohydramniosis.

    Coronary artery disease is the leading cause of morbidity and mortality in patients with type 2 diabetes. Screening for asymptomatic coronary artery disease with treatment by means of revascularization seems to be an appealing option for prevention. The utility of such a strategy has never been challenged in a randomized trial. In the present study a cohort of diabetic patients without any symptoms and without known coronary artery disease will be screened at two diabetes outpatients services. Those with intermediate or high risk (equal or greater than 10% according to the Italian risk chart) will be asked to participate and enrolled. They will be seen and followed in order to provide the best adherence to medical therapy. Half of the patients will be randomized to undergo an exercise tolerance testing while the other group will continue to be regularly seen at diabetes outpatients services. Best medical/behavioral therapy will be offered to both groups. Those patients with a positive exercise tolerance testing will be studied by coronary angiography and treated according to the severity of coronary lesions by percutaneous stenting or surgery.The objective of the study is to evaluate the efficacy of the screening strategy aimed at revascularization. A cost-effectiveness analysis will be performed at the end of the follow up. The study will provide useful information about prevention and treatment of diabetic patients at high risk of coronary events. It will be made clearer if detection of silent coronary artery disease has to be recommended and followed by treatment. Given the simplicity of the study protocol, it will be easily transferable to the real world. (ClinicalTrials.gov): NCT00547872.

    International audience; Standardized neurofeedback (NF) protocols have been extensively evaluated in attention-deficit/hyperactivity disorder (ADHD). However, such protocols do not account for the large EEG heterogeneity in ADHD. Thus, individualized approaches have been suggested to improve the clinical outcome. In this direction, an open-label pilot study was designed to evaluate a NF protocol of relative upper alpha power enhancement in fronto-central sites. Upper alpha band was individual...

    To examine the effectiveness of playing chess as a treatment option for children with ADHD. Parents of 44 children ages 6 to 17 with a primary diagnosis of ADHD consented to take part in the study. Parents completed the Spanish version of the Swanson, Nolan and Pelham Scale for parents (SNAP-IV) and the Abbreviated Conner's Rating Scales for parents (CPRS-HI) prior to an 11-week chess-training program. We used a paired t-test to compare pre- and post-intervention outcomes, and Cohen-d calculations to measure the magnitude of the effect. The statistical significance was set at Pchess could be included within the multimodal treatment of ADHD. Copyright © 2014 SEP y SEPB. Published by Elsevier España. All rights reserved.

    The phase 3 randomized SQUIRE study revealed significantly longer overall survival (OS) and progression-free survival (PFS) for necitumumab plus gemcitabine and cisplatin (neci+GC) than for gemcitabine and cisplatin alone (GC) in 1,093 patients with previously untreated advanced squamous non-small cell lung cancer (NSCLC). This post hoc subgroup analysis assessed the efficacy and safety of neci+GC among East Asian (EA) patients enrolled in the study. All patients received up to six 3-week cycles of gemcitabine (days 1 and 8, 1,250 mg/m²) and cisplatin (day 1, 75 mg/m²). Patients in the neci+GC arm also received necitumumab (days 1 and 8, 800 mg) until disease progression or unacceptable toxicity. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated from stratified Cox proportional hazards models. In EA patients, there were improvements for neci+GC (n=43) versus GC (n=41) in OS (HR, 0.805; 95% CI, 0.484 to 1.341) and PFS (HR, 0.720; 95% CI, 0.439 to 1.180), consistent with the results for non-EA patients observed in the present study. The overall safety data were consistent between EA and non-EA patients. A numerically higher proportion of patients experienced serious adverse events (AEs), grade ≥ 3 AEs, and AEs with an outcome of death for neci+GC versus GC in EA patients and EA patients versus non-EA patients for neci+GC. Although limited by the small sample size and post hoc nature of the analysis, these findings are consistent with those of the overall study and suggest that neci+GC offers a survival advantage and favorable benefit/risk for EA patients with advanced squamous NSCLC.

    We aimed to investigate whether gatifloxacin, a new generation and affordable fluoroquinolone, is better than chloramphenicol for the treatment of uncomplicated enteric fever in children and adults. We did an open-label randomised superiority trial at Patan Hospital, Kathmandu, Nepal, to investigate whether gatifloxacin is more effective than chloramphenicol for treating uncomplicated enteric fever. Children and adults clinically diagnosed with enteric fever received either gatifloxacin (10 mg/kg) once a day for 7 days, or chloramphenicol (75 mg/kg per day) in four divided doses for 14 days. Patients were randomly allocated treatment (1:1) in blocks of 50, without stratification. Allocations were placed in sealed envelopes opened by the study physician once a patient was enrolled into the trial. Masking was not possible because of the different formulations and ways of giving the two drugs. The primary outcome measure was treatment failure, which consisted of at least one of the following: persistent fever at day 10, need for rescue treatment, microbiological failure, relapse until day 31, and enteric-fever-related complications. The primary outcome was assessed in all patients randomly allocated treatment and reported separately for culture-positive patients and for all patients. Secondary outcome measures were fever clearance time, late relapse, and faecal carriage. The trial is registered on controlled-trials.com, number ISRCTN 53258327. 844 patients with a median age of 16 (IQR 9-22) years were enrolled in the trial and randomly allocated a treatment. 352 patients had blood-culture-confirmed enteric fever: 175 were treated with chloramphenicol and 177 with gatifloxacin. 14 patients had treatment failure in the chloramphenicol group, compared with 12 in the gatifloxacin group (hazard ratio [HR] of time to failure 0·86, 95% CI 0·40-1·86, p=0·70). The median time to fever clearance was 3·95 days (95% CI 3·68-4·68) in the chloramphenicol group and 3·90 days

    Although it has been suggested that selective decontamination of the digestive tract (SDD) decreases postoperative aerobic Gram-negative and fungal infections in orthotopic liver transplantation (OLT), no controlled trials exist in pediatric patients. This prospective, randomized controlled study of 36 pediatric OLT patients examines the effect of short-term SDD on postoperative infection and digestive tract flora. Patients were randomized into two groups. The control group received perioperative parenteral antibiotics only. The SDD group received in addition polymyxin E, tobramycin, and amphotericin B enterally and by oropharyngeal swab postoperatively until oral intake was tolerated (6 +/- 4 days). Indications for operation, preoperative status, age, and intensive care unit and hospital length of stay were no different in SDD (n = 18) and control (n = 18) groups. A total of 14 Gram-negative infections (intraabdominal abscess 7, septicemia 5, pneumonia 1, urinary tract 1) developed in the 36 patients studied. Mortality was not significantly different in the two groups. However, there were significantly fewer patients with Gram-negative infections in the SDD group: 3/18 patients (11%) vs. 11/18 patients (50%) in the control group, P < 0.001. There was also significant reduction in aerobic Gram-negative flora in the stool and pharynx in patients receiving SDD. Gram-positive and anaerobic organisms were unaffected. We conclude that short-term postoperative SDD significantly reduces Gram-negative infections in pediatric OLT patients.

    Objective: The objective of this research is to investigate the effects of electroencephalogram (EEG) biofeedback training of alpha activity over the parietal lobe in patients with generalized anxiety disorder (GAD), and to compare the effects of training of alpha activity over the left parietal lobe and right parietal lobe in patients with GAD. Methods: Twenty-six female patients with GAD according to the Diagnostic and Statistical Manual of Mental Disorders (4th edition, DSM-IV) criteria for GAD were included in this study, and these patients were randomized into two groups: the left parietal lobe training group (n = 13) and the right parietal lobe training group (n = 13). Patients received a total of 10 times training, in which each training consisted of a 40 minutes training session every three days. The degree of anxiety, depression and insomnia symptoms before the first time training, after the fifth time training and after the last time training were evaluated using the State-Trait Anxiety Inventory (STAI), Beck Depression Inventory (BDI-II) and Insomnia Severity Index (ISI). Results: In the left parietal lobe training group, the scores of STAI-S[(38. 7 ±8. 8), (35. 2 ±9. 2) vs. (47. 2 ± 10. 7), P <0. 05] and ISI[(13.0 ±5. 2),(8.4 ±4.7) vs. (17.5 ±5. 3), P <0. 05] decreased after 5 and 10 times of training. In the right parietal lobe training group, the scores of STAI-S[(37. 3 ± 6. 4), (29. 9 ± 6. 2) vs. (44. 9 ± 12. 4), P < 0. 05], STAI-T[ (40.9 ±6.4),(36.9 ±6.9) vs. (47. 8 ±7. 5), P<0. 05]and ISI[ (10. 2 ±5.1), (6. 9 ±3. 1) vs. (15.5 ±6.9),P< 0. 05] decreased after 5 and 10 times of training. The BDI-II scores [ (10. 3 ± 6. 0) vs. (17. 7 ±7. 2), P <0. 05] decreased after 10 times of training. Conclusion: Our findings suggest that EEG biofeedback training of alpha activity over the parietal lobe could improve the anxiety and insomnia symptom in patients with GAD. EEG biofeedback training of alpha activity over the right parietal lobe could

    The benefit of CT coronary angiography (CTCA) in patients presenting with stable chest pain has not been systematically studied. We aimed to assess the effect of CTCA on the diagnosis, management, and outcome of patients referred to the cardiology clinic with suspected angina due to coronary heart disease. In this prospective open-label, parallel-group, multicentre trial, we recruited patients aged 18-75 years referred for the assessment of suspected angina due to coronary heart disease from 12 cardiology chest pain clinics across Scotland. We randomly assigned (1:1) participants to standard care plus CTCA or standard care alone. Randomisation was done with a web-based service to ensure allocation concealment. The primary endpoint was certainty of the diagnosis of angina secondary to coronary heart disease at 6 weeks. All analyses were intention to treat, and patients were analysed in the group they were allocated to, irrespective of compliance with scanning. This study is registered with ClinicalTrials.gov, number NCT01149590. Between Nov 18, 2010, and Sept 24, 2014, we randomly assigned 4146 (42%) of 9849 patients who had been referred for assessment of suspected angina due to coronary heart disease. 47% of participants had a baseline clinic diagnosis of coronary heart disease and 36% had angina due to coronary heart disease. At 6 weeks, CTCA reclassified the diagnosis of coronary heart disease in 558 (27%) patients and the diagnosis of angina due to coronary heart disease in 481 (23%) patients (standard care 22 [1%] and 23 [1%]; pheart disease increased (1·09, 1·02-1·17; p=0·0172), the certainty increased (1·79, 1·62-1·96; pheart disease. This changed planned investigations (15% vs 1%; pheart disease, CTCA clarifies the diagnosis, enables targeting of interventions, and might reduce the future risk of myocardial infarction.

    Purpose To investigate influences of 3% diquafosol sodium ophthalmic solution (DQS) on ocular surface after cataract surgery and effects on postoperative dry eye. Design This study had two consecutive prospective study phases. The former was an observational study from before cataract surgery to 4 weeks after surgery and the latter was a randomized open-label study from 4 to 8 weeks after surgery. Methods Subjects were 433 eyes of 433 patients undergoing cataract surgery with intraocular lens implantation. Dry eye examination of tear breakup time (BUT), corneal and conjunctival fluorescein staining scores, total subjective symptom score (12 symptoms), and Schirmer I test were conducted before surgery and 4 weeks after surgery. Patient demographics and these examination results were used to analyze risk factors to predict postoperative dry eye. In a randomized study, 154 eyes diagnosed with dry eye postoperatively were applied either DQS or artificial tears (AT) six times daily for 4 weeks. The data of the examinations were compared. Results At 4 weeks after surgery, BUT was shortened significantly (P=0.036), fluorescein staining score increased significantly (P=0.012), but total subjective symptom score was significantly improved (Pdry eye was shortened BUT type (53.1%). The dry eye prevalence after surgery decreased (55.7%) compared with before surgery (69.7%). Females and the patient with dry eye symptoms before surgery had significant risk factors for postoperative dry eye. In a randomized study, BUT was significantly prolonged in the DQS group (P=0.015), but not in the AT group. Fluorescein staining score was significantly improved in both groups (P<0.001). Total subjective symptom score was significantly decreased in the AT group (P<0.001), but not in the DQS group. Conclusion Our study suggests that cataract surgery has harmful effects on tear film stability and ocular surface, and DQS has a capability to improve them. PMID:28360509

The safety of tipepidine in children and adults has already been established. It is reported that tipepidine inhibits G-protein-coupled inwardly rectifying potassium (GIRK-channel currents. The inhibition of GIRK channels by tipepidine is expected to modulate the level of monoamines in the brain. We put forward the hypothesis that tipepidine can improve attention deficit/hyperactivity disorder (ADHD symptoms by modulating monoaminergic neurotransmission through the inhibition of GIRK channels. The purpose of this open-label trial was to confirm whether treatment with tipepidine can improve symptoms in pediatric patients with ADHD.Subjects and methods: This was a 4-week, open-label, proof-of-efficacy pilot study for pediatric subjects with ADHD. Ten pediatric ADHD subjects (70% male; mean age, 9.9 years; combined [inattentive and hyperactive/impulsive] subtype, n=7; inattentive subtype, n=3; hyperimpulsive subtype, n=0 received tipepidine hibenzate taken orally at 30 mg/day for 4 weeks. All subjects were assessed using the ADHD Rating Scale IV (ADHD-RS, Japanese version, and the Das–Naglieri Cognitive Assessment System (DN-CAS, Japanese version.Results: A comparison of baseline scores and 4-week end-point scores showed that all the ADHD-RS scores (total scores, hyperimpulsive subscores, and inattentive subscores

    Autism spectrum disorders (ASD) are recognized as a major public health issue. Here, we evaluated the effects of folic acid intervention on methylation cycles and oxidative stress in autistic children enrolled in structured teaching. Sixty-six autistic children enrolled in this open-label trial and participated in three months of structured teaching. Forty-four children were treated with 400 μg folic acid (two times/daily) for a period of three months during their structured teaching (intervention group), while the remaining 22 children were not given any supplement for the duration of the study (control group). The Autism Treatment Evaluation Checklist (ATEC) and Psychoeducational Profile-third edition (PEP-3) were measured at the beginning and end of the treatment period. Folic acid, homocysteine, and glutathione metabolism in plasma were measured before and after treatment in 29 autistic children randomly selected from the intervention group and were compared with 29 age-matched unaffected children (typical developmental group). The results illustrated folic acid intervention improved autism symptoms towards sociability, cognitive verbal/preverbal, receptive language, and affective expression and communication. Furthermore, this treatment also improved the concentrations of folic acid, homocysteine, and normalized glutathione redox metabolism. Folic acid supplementation may have a certain role in the treatment of children with autism.

    Full Text Available Abstract Background Guidelines for the control of hospital-acquired MRSA include decolonization measures to end MRSA carrier status in colonized and infected patients. Successful decolonization typically requires up to 22 days of treatment, which is longer than the average hospital length of stay (LOS. Incomplete decolonization is therefore common, with long-term MRSA carriage as a consequence. To overcome this, we developed an integrated MRSA Management (IMM by extending MRSA decolonization to the outpatient and domestic setting. The protocol makes use of polyhexanide-based products, in view of reported qac-mediated resistance to chlorhexidine in S. aureus and MRSA. Methods This is a prospective, single centre, controlled, non-randomized, open-label study to evaluate the efficiency of the IMM concept. The outcome of guideline-approved decolonization during hospital stay only (control group; n = 201 was compared to the outcome following IMM treatment whereby decolonization was continued after discharge in the domestic setting or in a long-term care facility (study group; n = 99. As a secondary outcome, the effect of MRSA-status of skin alterations was assessed. Results The overall decolonization rate was 47 % in the IMM patient group compared to 12 % in the control group (p  0.05. For patients with skin alterations (e.g. wounds and entry sites, decolonization success was 50 % if the skin alterations were MRSA-negative at baseline, compared to 22 % success for patients entering the study with MRSA-positive skin alterations (p < 0.01. Conclusions The IMM strategy offers an MRSA decolonization protocol that is feasible in the domestic setting and is equally effective compared with inpatient decolonization treatment when hospital LOS is long enough to complete the treatment. Moreover, for patients with average LOS, decolonization rates obtained with IMM are significantly higher than for in-hospital treatment. IMM is a promising

    Sleep disturbance is the second most bothersome symptom in patients with cancer, and it can significantly impair their quality of life. The aim of this study was to investigate the efficacy and safety of the traditional herbal medicine Gamiguibi-tang (GGBT) in patients with cancer-related sleep disturbance. We conducted a prospective, randomized, wait-list-controlled, open-label pilot clinical trial on cancer-related sleep disturbance. Patients with cancer experiencing poor sleep quality with a Pittsburgh Sleep Quality Index of at least 6 were randomly assigned to the GGBT and wait-list groups to receive GGBT and conventional care, respectively, for 2 weeks. The primary endpoint was the Insomnia Severity Index (ISI) score. Fatigue, depression, and cognitive impairment were assessed as the secondary endpoints by using the Brief Fatigue Inventory (BFI), Beck Depression Inventory (BDI), and Montreal Cognitive Assessment (MoCA). Thirty participants who met the eligibility criteria were enrolled. Sleep disturbance assessed using the ISI improved significantly more in the GGBT group than in the wait-list group (-5.5 ± 4.4 vs 0.1 ± 1.1, P < .001). Fatigue level determined using the BFI also improved significantly more in the GGBT group than in the wait-list group (-0.8 ± 0.8 vs 0.0 ± 0.3, P = .002). The BDI and MoCA scores showed no significant changes. Adverse events were reported in two patients in the GGBT group and consisted of mild dyspepsia and mild edema. GGBT may be a potential treatment option for cancer-related sleep disturbance. Further research is needed to investigate the efficacy and safety of GGBT.

    Protein-energy wasting (PEW) is increasingly becoming a clinical problem in maintenance hemodialysis patients and guidelines call for nutritional interventions. Serum prealbumin (transthyretin) represents a critical nutritional marker positively correlated with patient survival and negatively correlated with morbidity. Nutritional counseling, oral supplementation as well as intradialytic parenteral nutrition (IDPN) are recommended to fight PEW, however clinical trials on their use are scarce. We conducted a prospective, multicenter, randomized, open-label, controlled, parallel-group Phase IV clinical trial in 107 maintenance hemodialysis patients suffering from PEW to assess the impact of IDPN on prealbumin and other biochemical and clinical parameters reflecting nutritional status. Patients randomized to the intervention group received standardized nutritional counseling plus IDPN three times weekly over 16 weeks followed by a treatment-free period of 12 weeks. The control group received standardized nutritional counseling only. Main trial inclusion criteria included moderate to severe malnutrition (SGA score B or C), maintenance hemodialysis therapy (3 times per week) for more than six months, and presence of two out of the following three criteria: albumin 30 mg/L at week 16 (48.7% vs. 31.8%). Prealbumin response to IDPN therapy was more prominent in patients suffering from moderate malnutrition (SGA score B) compared to patients with severe malnutrition (SGA score C). The results of this trial demonstrate for the first time that IDPN therapy, given three times weekly in a 16-week short-term intervention, results in a statistically significant and clinically relevant increase in mean serum prealbumin, a surrogate marker for outcome and survival in hemodialysis patients suffering from PEW, and is superior to nutritional counseling.

    Metatarsus adductus is a common pediatric foot deformity related to intrauterine molding. It is usually a mild deformity that responds well to simple observation or minimal treatment with a home program of stretching. Resistant cases may need a more aggressive approach such as serial casting or special bracing to avoid the need for surgical intervention. We compared clinical outcomes using serial casting with orthoses for resistant metatarsus adductus. We prospectively treated 27 infants (43 feet) between the ages 3 and 9 months who failed home stretching treatment. Patients were randomized to either serial plaster casting or Bebax orthoses. Footprints and simulated weight-bearing anteroposterior and lateral view radiographs were made at entry and follow-up. There was no statistical difference between casting and Bebax for the following parameters: age at study entry, length of treatment, number of clinic visits, follow-up, and follow-up maintenance treatments. Both groups showed improvement in footprint and radiographic measurements post-treatment, without worsening of heel valgus. The Bebax group had greater improvement in the footprint heel bisector measurement than the casting group. The Bebax treatment requires more active parental cooperation. A simulated cost analysis of materials and office visit charges, however, revealed that Bebax treatment was significantly less expensive, about half the cost of casting. Because of the cost savings and virtually identical clinical results, we recommend the Bebax orthosis for resistant metatarsus in pre-walking infants with parents who are compliant. Other considerations include specific insurance plans, which may pay for casts but not orthoses.

    Full Text Available Background and objectives: Acetylcholinesterase inhibitors may cause postoperative residual curarization when they are used for reversal of neuromuscular blockade. Sugammadex reverses neuromuscular blockade by chemical encapsulation and is not associated with the side effects that may occur with the use of anticholinesterase agents. Because of increased outpatient surgical procedures postoperative residual curarization and rapid postoperative recovery have a greater importance in the pediatric patient population. The aim of this study was to compare the efficacy of sugammadex and neostigmine on reversing neuromuscular blockade in pediatric patients undergoing outpatient surgical procedures. Methods: 80 patients, aged 2-12 years, scheduled for outpatient surgery were enrolled in this randomized prospective study. Neuromuscular blockade was achieved with 0.6 mgkg−1 rocuronium and monitorized with train-of-four. Group RN (n = 40 received 0.03 mgkg−1 neostigmine, Group RS (n = 40 received 2 mgkg−1 sugammadex for reversal of rocuronium. Extubation time (time from the reversal of neuromuscular blockade to extubation, train-of-four ratio during this time, time to reach train-of-four > 0.9, and probable complications were recorded. Results: There was no significant difference between the patients' characteristics. Extubation time and time to reach train-of-four > 0.9 were significantly higher in Group RN (p = 0.001, p = 0.002. Train-of-four at the time of neostigmine/sugammadex injection in Group RN were significantly higher than in the RS group (p = 0.020. Extubation train-of-four ratio was significantly lower in Group RN (p = 0.002. Conclusion: Sugammadex provides safer extubation with a shorter recovery time than neostigmine in pediatric patients undergoing outpatient surgical procedures.

    The newly developed S-flurbiprofen plaster (SFPP) is a tape-type patch that shows innovative percutaneous absorption. This study was designed to evaluate the safety of a long-term 52-week SFPP application to osteoarthritis (OA) patients. This was a multi-center, open-label, uncontrolled prospective study that included 201 OA patients. SFPP at 40 mg/day was applied to the site of pain in 101 patients and at 80 mg/day (2 patches) in 100 patients at a total of 301 sites for 52 weeks. The affected sites assessed included the knee (192), lumbar spine (66), cervical spine (26), and others (17). Drug safety was evaluated by medical examination, laboratory tests, and examination of vital signs. Efficacy was evaluated by the patient's and clinician's global assessments and clinical symptoms. Most patients (80.1 %) completed the 52-week SFPP application. The majority of drug-related adverse events (AEs) included mild dermatitis at the application sites and occurred in 46.8 % of the sites. No photosensitive dermatitis was observed. Systemic AEs occurred in 9.0 % of the patients; a serious AE (gastric ulcer hemorrhage) occurred in one patient. No clinically significant changes in the laboratory tests and vital signs were observed. The efficacy evaluation showed an improvement from 2 weeks after the SFPP application, which continued during the 52 weeks' treatment. No apparent safety concerns were observed, even during the long-term SFPP application. Therefore, SFPP could be an additional pharmacotherapy in OA treatment.

    To date, placebo-controlled drug trials targeting the core social impairment of autistic disorder (autism) have had uniformly negative results. Given this, the search for new potentially novel agents targeting the core social impairment of autism continues. Acamprosate is U.S. Food and Drug Administration-approved drug to treat alcohol dependence. The drug likely impacts both gamma-aminobutyric acid and glutamate neurotransmission. This study describes our initial open-label experience with acamprosate targeting social impairment in youth with autism. In this naturalistic report, five of six youth (mean age, 9.5 years) were judged treatment responders to acamprosate (mean dose 1,110 mg/day) over 10 to 30 weeks (mean duration, 20 weeks) of treatment. Acamprosate was well tolerated with only mild gastrointestinal adverse effects noted in three (50%) subjects.

    To evaluate potential development of tolerance to adjunctive clobazam in patients with Lennox-Gastaut syndrome. Eligible patients enrolled in open-label extension study OV-1004, which continued until clobazam was commercially available in the United States or for a maximum of 2 years outside the United States. Enrolled patients started at 0.5 mg·kg -1 ·d -1 clobazam, not to exceed 40 mg/d. After 48 hours, dosages could be adjusted up to 2.0 mg·kg -1 ·d -1 (maximum 80 mg/d) on the basis of efficacy and tolerability. Post hoc analyses evaluated mean dosages and drop-seizure rates for the first 2 years of the open-label extension based on responder categories and baseline seizure quartiles in OV-1012. Individual patient listings were reviewed for dosage increases ≥40% and increasing seizure rates. Data from 200 patients were included. For patients free of drop seizures, there was no notable change in dosage over 24 months. For responder groups still exhibiting drop seizures, dosages were increased. Weekly drop-seizure rates for 100% and ≥75% responders demonstrated a consistent response over time. Few patients had a dosage increase ≥40% associated with an increase in seizure rates. Two-year findings suggest that the majority of patients do not develop tolerance to the antiseizure actions of clobazam. Observed dosage increases may reflect best efforts to achieve seizure freedom. It is possible that the clinical development of tolerance to clobazam has been overstated. NCT00518713 and NCT01160770. This study provides Class III evidence that the majority of patients do not develop tolerance to clobazam over 2 years of treatment. © 2016 American Academy of Neurology.

    Freezing of gait (FOG) and falls are major sources of disability for Parkinson's disease (PD) patients, and show limited responsiveness to medications. We assessed the efficacy of visual cues for overcoming FOG in an open-label study of 26 patients with PD. The change in the frequency of falls was a secondary outcome measure. Subjects underwent a 1-2 month baseline period of use of a cane or walker without visual cues, followed by 1 month using the same device with the laserlight visual cue. The laserlight visual cue was associated with a modest but significant mean reduction in FOG Questionnaire (FOGQ) scores of 1.25 ± 0.48 (p = 0.0152, two-tailed paired t-test), representing a 6.6% improvement compared to the mean baseline FOGQ scores of 18.8. The mean reduction in fall frequency was 39.5 ± 9.3% with the laserlight visual cue among subjects experiencing at least one fall during the baseline and subsequent study periods (p = 0.002; two-tailed one-sample t-test with hypothesized mean of 0). Though some individual subjects may have benefited, the overall mean performance on the timed gait test (TGT) across all subjects did not significantly change. However, among the 4 subjects who underwent repeated testing of the TGT, one showed a 50% mean improvement in TGT performance with the laserlight visual cue (p = 0.005; two-tailed paired t-test). This open-label study provides evidence for modest efficacy of a laserlight visual cue in overcoming FOG and reducing falls in PD patients. Copyright © 2010 Elsevier Ltd. All rights reserved.

    Machine learning methods that have been used in data-driven predictive modeling of mineral prospectivity (e.g., artificial neural networks) invariably require large number of training prospect/locations and are unable to handle missing values in certain evidential data. The Random Forests (RF) algorithm, which is a machine learning method, has recently been applied to data-driven predictive mapping of mineral prospectivity, and so it is instructive to further study its efficacy in this particular field. This case study, carried out using data from Abra (Philippines), examines (a) if RF modeling can be used for data-driven modeling of mineral prospectivity in areas with a few (i.e., individual layers of evidential data. Furthermore, RF modeling can handle missing values in evidential data through an RF-based imputation technique whereas in WofE modeling values are simply represented by zero weights. Therefore, the RF algorithm is potentially more useful than existing methods that are currently used for data-driven predictive mapping of mineral prospectivity. In particular, it is not a purely black-box method like artificial neural networks in the context of data-driven predictive modeling of mineral prospectivity. However, further testing of the method in other areas with a few mineral occurrences is needed to fully investigate its usefulness in data-driven predictive modeling of mineral prospectivity.

    Full Text Available Abstract Background Cardiomyopathy is a leading cause of morbidity and mortality in boys with Duchenne muscular dystrophy (DMD. We recently showed in a 12-month double-blind randomized controlled trial that adding eplerenone to background medical therapy was cardioprotective in this population. The objective of this study was to evaluate the safety and efficacy of longer-term eplerenone therapy in boys with DMD. Results Eleven subjects (phase 1 baseline median [range] age: 13 [7 – 25] years from the original 12-month trial at a single participating center were enrolled. Importantly, those who entered the extension study who had been on eplerenone previously were significantly older than those who had originally been on placebo (median age 10.5 vs. 18.0 years, p = 0.045. During an additional 24-month open-label extension study, all boys received eplerenone 25 mg orally once daily to treat preclinical DMD cardiomyopathy, defined as evident myocardial damage by late gadolinium enhancement cardiac magnetic resonance (LGE with preserved ejection fraction (EF. The threshold for potassium level, the primary safety measure, was not exceeded in any non-hemolyzed blood sample. Over 24 months, left ventricular (LV systolic strain, a more sensitive marker whose more negative values indicate greater contractility significantly improved (median change -4.4%, IQR -5.8 to -0.9% in younger subjects whereas older subjects’ strain remained stable without significant worsening or improvement (median change 0.2%, IQR -1.1 to 4.3%. EF and extent of myocardial damage by LGE remained stable in both groups over 2 years. Conclusions Eplerenone offers effective and safe cardioprotection for boys with DMD, particularly when started at a younger age. Eplerenone is a useful clinical therapeutic option, particularly if treatment is initiated earlier in life when cardiac damage is minimal.

    Nonsuicidal self-injury (NSSI) is common in adolescents and young adults, and few evidence-based treatments are available for this significant problem. N-acetylcysteine (NAC) is a widely available nutritional supplement that has been studied in some psychiatric disorders relevant to NSSI including mood and addictive disorders. This pilot study tested the use of NAC as a potential treatment for NSSI in youth. Thirty-five female adolescents and young adults with NSSI aged 13-21 years were enrolled in this study that had an open-label, single-arm study design. All participants were given oral NAC as follows: 600 mg twice daily (weeks 1-2), 1200 mg twice daily (weeks 3-4), and 1800 mg twice daily (weeks 5-8). Patients were seen every 2 weeks throughout the trial, at which time youth reported the frequency of NSSI episodes. Levels of depression, impulsivity, and global psychopathology were measured at baseline and at the end of the trial using the Beck Depression Inventory-II (BDI-II), Barratt Impulsivity Scale, and Symptoms Checklist-90 (SCL-90). About two-thirds of the enrolled female youth completed the trial (24/35). NAC was generally well tolerated in this sample. NAC treatment was associated with a significant decrease in NSSI frequency at visit 6 and visit 8 compared to baseline. We also found that depression scores and global psychopathology scores (but not impulsivity scores) decreased after NAC treatment. Decrease in NSSI was not correlated with decrease in BDI-II or SCL-90 scores, suggesting these might be independent effects. We provide preliminary evidence that NAC may have promise as a potential treatment option for adolescents with NSSI. The current results require follow-up with a randomized, placebo-controlled trial to confirm efficacy.

    BL-1020, a novel gamma aminobutyric acid (GABA) ester of perphenazine, is a new oral antipsychotic with a strong affinity for dopamine and serotonin receptors. Unlike first- and second-generation antipsychotics, it has agonist activity at GABA(A). This is the first study to examine tolerability and safety of BL-1020 in schizophrenia. This was a phase-II, open-label, multicenter, 6-week study treating patients (n = 36) with chronic schizophrenia. Dosing started at 20 mg/d and increased over 7 days to 40 mg/d. Weekly assessments were conducted. All but 1 patient was titrated to 30 mg/d at day 4; on day 7, 30 were titrated to 40 mg/d. Four patients discontinued the study prematurely. There was no clinically relevant increase in vital signs, sedation, dizziness, or other central nervous system effects or electrocardiogram or laboratory abnormalities and a small increase in weight. Ten patients experienced extrapyramidal symptoms (EPS) requiring treatment with an anticholinergic; 4 patients were unable to reach maximum dose because of EPS. Extrapyramidal Symptom Rating Scale did not indicate clinically significant changes in EPS. The most common adverse event was insomnia (6 patients); other frequent adverse effects (all n = 3) were extrapyramidal disorder, headache, parkinsonism, tremor, and hyperprolactinemia. There was improvement on Positive and Negative Syndrome Scale and Clinical Global Impression of Change with 22 patients showing at least 20% decrease by end point on Positive and Negative Syndrome Scale and 31 patients showing at least minimal improvement on Clinical Global Impression of Change. These data suggest that 20 to 40 mg/d of BL-1020 is associated with clinically relevant improvement of psychosis with no worsening of EPS and support further testing in randomized controlled trials.

    Cognitive difficulties are common in epilepsy. Beyond reducing seizures and adjusting antiepileptic medications, no well-validated treatment exists in adults. Methylphenidate is used effectively in children with epilepsy and attention-deficit/hyperactivity disorder, but its effects in adults have not been systematically evaluated. We hypothesized that methylphenidate can safely improve cognition in adults with epilepsy. We detail here the open-label follow-up to a double-blind, placebo-controlled, single-dose study. Thirty epilepsy patients entered a 1-month open-label methylphenidate trial after a double-blind phase. Doses were titrated according to clinical practice and patient tolerance, ranging 20-40 mg/day. Primary measures included: Conners' Continuous Performance Test (CPT), Symbol-Digit Modalities Test (SDMT), and Medical College of Georgia Memory Test (MCG). Secondary measures were: Beck Depression Inventory, 2nd Edition (BDI-II), Beck Anxiety Inventory, Apathy Evaluation Scale (AES), Stimulant Side-Effect Checklist, Adverse Events Profile, Quality of Life in Epilepsy-89 (QOLIE-89), and seizure frequency. Fourteen healthy, nonmedicated controls were tested concurrently. Twenty-eight participants with epilepsy (13 men/15 women) completed the trial. Withdrawals occurred due to anxiety (n = 1) and fatigue (n = 1). Mean age was 36.4 years (range = 20-60). Epilepsy types were: focal (n = 21), generalized (n = 6), or unclassified (n = 1). Mean epilepsy duration was 12.3 years. Mean baseline seizure frequency was 2.8/month. There were significant improvements on methylphenidate for SDMT, MCG, CPT (the ability to discriminate between targets and nontargets [d'] hits, hit reaction time standard deviation, omissions, and commissions), and QOLIE subscales (energy/fatigue, attention/concentration, memory, and language; paired t tests; p ≤ 0.002). BDI-II and additional subscales also improved, at a lower level of statistical significance. Effect

    Full Text Available Background: Attention Deficit Hyperactivity Disorder (ADHD is a common psychiatric disorder among children and adolescents. This disorder causes difficulties in academic, behavioral, emotional, social and family performance. Stimulants show robust efficacy and a good safety profile in children with this disorder, but a significant percent of ADHD children do not respond adequately or cannot tolerate the associated adverse effects with stimulants. Such difficulties highlight the need for alternative safe and effective medications in the treatment of this disorder. This open-label study assessed the effectiveness of reboxetine, a selective norepinephrine reuptake inhibitor, in children and adolescents with attention deficit hyperactivity disorder (ADHD."nMethods: Fifteen child and adolescent outpatients, aged 7 to 16 (Mean± SD=9.72±2.71 years, diagnosed with ADHD were enrolled in a six open-label study with reboxetine 4-6 mg/d. The principal measure of the outcome was the teacher and parent Attention Deficit Hyperactive Disorder Rating Scale (ADHD Rating Scale. Patients were assessed by a child psychiatrist at baseline, 2, 4 and 6 weeks of the medication started. Side effects questionnaire was used to detect side effects of reboxetine.

    Full Text Available In polypharmacy patients under home health management, pharmacogenetic testing coupled with guidance from a clinical decision support tool (CDST on reducing drug, gene, and cumulative interaction risk may provide valuable insights in prescription drug treatment, reducing re-hospitalization and emergency department (ED visits. We assessed the clinical impact of pharmacogenetic profiling integrating binary and cumulative drug and gene interaction warnings on home health polypharmacy patients.This prospective, open-label, randomized controlled trial was conducted at one hospital-based home health agency between February 2015 and February 2016. Recruitment came from patient referrals to home health at hospital discharge. Eligible patients were aged 50 years and older and taking or initiating treatment with medications with potential or significant drug-gene-based interactions. Subjects (n = 110 were randomized to pharmacogenetic profiling (n = 57. The study pharmacist reviewed drug-drug, drug-gene, and cumulative drug and/or gene interactions using the YouScript® CDST to provide drug therapy recommendations to clinicians. The control group (n = 53 received treatment as usual including pharmacist guided medication management using a standard drug information resource.

    Full Text Available Background and objectives: Acetylcholinesterase inhibitors may cause postoperative residual curarization when they are used for reversal of neuromuscular blockade. Sugammadex reverses neuromuscular blockade by chemical encapsulation and is not associated with the side effects that may occur with the use of anticholinesterase agents. Because of increased outpatient surgical procedures postoperative residual curarization and rapid postoperative recovery have a greater importance in the pediatric patient population. The aim of this study was to compare the efficacy of sugammadex and neostigmine on reversing neuromuscular blockade in pediatric patients undergoing outpatient surgical procedures. Methods: 80 patients, aged 2–12 years, scheduled for outpatient surgery were enrolled in this randomized prospective study. Neuromuscular blockade was achieved with 0.6 mg kg−1 rocuronium and monitorized with train-of-four. Group RN (n = 40 received 0.03 mg kg−1 neostigmine, Group RS (n = 40 received 2 mg kg−1 sugammadex for reversal of rocuronium. Extubation time (time from the reversal of neuromuscular blockade to extubation, train-of-four ratio during this time, time to reach train-of-four > 0.9, and probable complications were recorded. Results: There was no significant difference between the patients’ characteristics. Extubation time and time to reach train-of-four > 0.9 were significantly higher in Group RN (p = 0.001, p = 0.002. Train-of-four at the time of neostigmine/sugammadex injection in Group RN were significantly higher than in the RS group (p = 0.020. Extubation train-of-four ratio was significantly lower in Group RN (p = 0.002. Conclusion: Sugammadex provides safer extubation with a shorter recovery time than neostigmine in pediatric patients undergoing outpatient surgical procedures.

    Conflicting blood pressure-lowering effects of catheter-based renal artery denervation have been reported in patients with resistant hypertension. We compared the ambulatory blood pressure-lowering efficacy and safety of radiofrequency-based renal denervation added to a standardised stepped-care antihypertensive treatment (SSAHT) with the same SSAHT alone in patients with resistant hypertension. The Renal Denervation for Hypertension (DENERHTN) trial was a prospective, open-label randomised controlled trial with blinded endpoint evaluation in patients with resistant hypertension, done in 15 French tertiary care centres specialised in hypertension management. Eligible patients aged 18-75 years received indapamide 1·5 mg, ramipril 10 mg (or irbesartan 300 mg), and amlodipine 10 mg daily for 4 weeks to confirm treatment resistance by ambulatory blood pressure monitoring before randomisation. Patients were then randomly assigned (1:1) to receive either renal denervation plus an SSAHT regimen (renal denervation group) or the same SSAHT alone (control group). The randomisation sequence was generated by computer, and stratified by centres. For SSAHT, after randomisation, spironolactone 25 mg per day, bisoprolol 10 mg per day, prazosin 5 mg per day, and rilmenidine 1 mg per day were sequentially added from months two to five in both groups if home blood pressure was more than or equal to 135/85 mm Hg. The primary endpoint was the mean change in daytime systolic blood pressure from baseline to 6 months as assessed by ambulatory blood pressure monitoring. The primary endpoint was analysed blindly. The safety outcomes were the incidence of acute adverse events of the renal denervation procedure and the change in estimated glomerular filtration rate from baseline to 6 months. This trial is registered with ClinicalTrials.gov, number NCT01570777. Between May 22, 2012, and Oct 14, 2013, 1416 patients were screened for eligibility, 106 of those were randomly assigned to treatment

    Topical ketamine, an N-methyl-D-aspartate antagonist, has been shown to be effective in certain neuropathic pain syndromes. The objective of this study was to determine the efficacy of topical ketamine in spinal cord injury patients with neuropathic pain. An open label trial enrolled five subjects at an outpatient rehabilitation hospital with traumatic spinal cord injuries who had neuropathic pain at or below the level of injury. Subjects applied topical ketamine 10% three times a day for a two-week duration. Subjects recorded their numerical pain score-ranging from 0 to 10, with 0 representing "no pain, 5 representing "moderate pain," and 10 being described as "worst possible pain"-in a journal at the time of application of topical ketamine and one hour after application. Using a numerical pain scale allows for something as subjective as pain to be given an objective quantification. Subjects also recorded any occurrence of adverse events and level of satisfaction. All five subjects had a decrease in their numerical pain scale by the end of two weeks, ranging from 14% to 63%. The duration ranged from one hour in one subject to the next application in other subjects. There were no adverse effects. Overall, four out of the five subjects stated they were satisfied. Topical ketamine 10% is an effective neuropathic pain medicine in patients with spinal cord injuries; however, further studies need to be done with a placebo and larger sample size.

    Whilst the majority of evidence supports the adjunctive use of eicosapentaenoic acid (EPA) in improving mood, to date no study exists using low-dose docosahexaenoic acid (DHA) alone as an adjunctive treatment in patients with mild to moderate major depressive disorder (MDD). A naturalistic 8-week open-label pilot trial of low-dose DHA, (260 mg or 520 mg/day) in 28 patients with MDD who were non-responsive to medication or psychotherapy, with a Hamilton Depression Rating Scale (HAM-D) score of greater than 17, was conducted. Primary outcomes of depression, clinical severity, and daytime sleepiness were measured. After 8 weeks, 54% of patients had a ≥50% reduction on the HAM-D, and 45% were in remission (HAM-D ≤ 7). The eta-squared statistic (0.59) indicated a large effect size for the reduction of depression (equivalent to Cohen's d of 2.4). However confidence in this effect size is tempered due to the lack of a placebo. The mean score for the Clinical Global Impression Severity Scale was significantly improved by 1.28 points (P depression.

    Full Text Available Cellular therapy is an emerging therapeutic modality with a great potential for the treatment of autism. Recent findings show that the major underlying pathogenetic mechanisms of autism are hypoperfusion and immune alterations in the brain. So conceptually, cellular therapy which facilitates counteractive processes of improving perfusion by angiogenesis and balancing inflammation by immune regulation would exhibit beneficial clinical effects in patients with autism. This is an open label proof of concept study of autologous bone marrow mononuclear cells (BMMNCs intrathecal transplantation in 32 patients with autism followed by multidisciplinary therapies. All patients were followed up for 26 months (mean 12.7. Outcome measures used were ISAA, CGI, and FIM/Wee-FIM scales. Positron Emission Tomography-Computed Tomography (PET-CT scan recorded objective changes. Out of 32 patients, a total of 29 (91% patients improved on total ISAA scores and 20 patients (62% showed decreased severity on CGI-I. The difference between pre- and postscores was statistically significant (P<0.001 on Wilcoxon matched-pairs signed rank test. On CGI-II 96% of patients showed global improvement. The efficacy was measured on CGI-III efficacy index. Few adverse events including seizures in three patients were controlled with medications. The encouraging results of this leading clinical study provide future directions for application of cellular therapy in autism.

  3. Shelf Life of Food Products: From Open Labeling to Real-Time Measurements.

    The labels currently used on food and beverage products only provide consumers with a rough guide to their expected shelf lives because they assume that a product only experiences a limited range of predefined handling and storage conditions. These static labels do not take into consideration conditions that might shorten a product's shelf life (such as temperature abuse), which can lead to problems associated with food safety and waste. Advances in shelf-life estimation have the potential to improve the safety, reliability, and sustainability of the food supply. Selection of appropriate kinetic models and data-analysis techniques is essential to predict shelf life, to account for variability in environmental conditions, and to allow real-time monitoring. Novel analytical tools to determine safety and quality attributes in situ coupled with modern tracking technologies and appropriate predictive tools have the potential to provide accurate estimations of the remaining shelf life of a food product in real time. This review summarizes the necessary steps to attain a transition from open labeling to real-time shelf-life measurements.

    We sought to assess a novel, noninvasive, portable vagal nerve stimulator (nVNS) for acute treatment of migraine. Participants with migraine with or without aura were eligible for an open-label, single-arm, multiple-attack study. Up to four migraine attacks were treated with two 90-second doses, at 15-minute intervals delivered to the right cervical branch of the vagus nerve within a six-week time period. Subjects were asked to self-treat at moderate or severe pain, or after 20 minutes of mild pain. Of 30 enrolled patients (25 females, five males, median age 39), two treated no attacks, and one treated aura only, leaving a Full Analysis Set of 27 treating 80 attacks with pain. An adverse event was reported in 13 patients, notably: neck twitching (n = 1), raspy voice (n = 1) and redness at the device site (n = 1). No unanticipated, serious or severe adverse events were reported. The pain-free rate at two hours was four of 19 (21%) for the first treated attack with a moderate or severe headache at baseline. For all moderate or severe attacks at baseline, the pain-free rate was 12/54 (22%). nVNS may be an effective and well-tolerated acute treatment for migraine in certain patients. © International Headache Society 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Ischemic animal model studies have shown a neuroprotective effect of minocycline. To analyze the effect of minocycline treatment in human acute ischemic stroke. We performed an open-label, evaluator-blinded study. Minocycline at a dosage of 200 mg was administered orally for 5 days. The therapeutic window of time was 6 to 24 hours after onset of stroke. Data from NIH Stroke Scale (NIHSS), modified Rankin Scale (mRS), and Barthel Index (BI) were evaluated. The primary objective was to compare changes from baseline to day 90 in NIHSS in the minocycline group vs placebo. One hundred fifty-two patients were included in the study. Seventy-four patients received minocycline treatment, and 77 received placebo. NIHSS and mRS were significantly lower and BI scores were significantly higher in minocycline-treated patients. This pattern was already apparent on day 7 and day 30 of follow-up. Deaths, myocardial infarctions, recurrent strokes, and hemorrhagic transformations during follow-up did not differ by treatment group. Patients with acute stroke had significantly better outcome with minocycline treatment compared with placebo. The findings suggest a potential benefit of minocycline in acute ischemic stroke.

    Although compulsive buying (CB) is relatively common, pharmacotherapy research for CB is limited. Memantine, an N-methyl-D-aspartate receptor antagonist, appears to reduce glutamate excitability and improve impulsive behaviors, suggesting it may help individuals with CB. Nine patients (8 females) with CB were enrolled in a 10-week open-label treatment study of memantine (dose ranging from 10 to 30 mg/d). Participants were enrolled from December 2008 until May 2010. The primary outcome measure was change from baseline to study endpoint on the Yale-Brown Obsessive Compulsive Scale-Shopping Version (Y-BOCS-SV). Of the 9 participants, 8 (88.9%) completed the 10-week study. Y-BOCS-SV scores decreased from a mean of 22.0 ± 1.3 at baseline to 11.0 ± 5.3 at endpoint (P impulsive buying and improvements on cognitive tasks of impulsivity. In addition, the medication was well-tolerated. These findings suggest that pharmacologic manipulation of the glutamate system may target the impulsive behavior underlying CB. Placebo-controlled, double-blind studies are warranted in order to confirm these preliminary findings in a controlled design.

    The immature fragile skin of preterm infants represents an inadequate protective barrier. The emollient and anti-infective properties of coconut oil make it a potentially beneficial topical agent for this population. Our aim was to evaluate feasibility, safety, and the effects of topical coconut oil on skin condition in very preterm infants. An open-label randomised controlled trial in preterm infants coconut oil (5 mL/kg) twice daily for 21 days, starting within 24 h of birth. The neonatal skin condition was the primary outcome, and was assessed using the Neonatal Skin Condition Score (NSCS) on days 1, 7, 14, and 21. The number of coconut oil applications was recorded to assess clinical feasibility and all enrolled infants were monitored for adverse effects of topical coconut application, such as skin irritation. A total of 72 infants born coconut oil was feasible and without adverse effects. The NSCS was maintained in the coconut oil group throughout the intervention period, but deteriorated from a median (IQR) of 3 (3-4) on day 1 to 4 (4-4) on day 21 in the control group (p = 0.01). There were no differences in common neonatal outcomes, including sepsis, necrotising enterocolitis, retinopathy of prematurity, chronic lung disease, and mortality. Topical coconut oil maintained a better skin condition in very preterm infants without adverse effects. This simple, safe, and affordable intervention warrants further investigation. © 2017 S.

    Omega-3 polyunsaturated fatty acids (n-3 PUFAs) show beneficial effects on cardiovascular health and cognitive functions, but the underlying molecular mechanisms are not completely understood. Because of the fact that cytoskeleton dynamics affect almost every cellular process, the regulation of cytoskeletal dynamics could be a new pathway by which n-3 PUFAs exert their effects on cellular level. A 12-week open-label intervention study with 12 healthy men was conducted to determine the effects of 2.7 g/d n-3 PUFA on changes in mRNA expression of cytoskeleton-associated genes by quantitative real-time PCR in whole blood. Furthermore, the actin content in red blood cells was analyzed by immunofluorescence imaging. N-3 PUFA supplementation resulted in a significant down-regulation of cytoskeleton-associated genes, in particular three GTPases (RAC1, RHOA, CDC42), three kinases (ROCK1, PAK2, LIMK), two Wiskott-Aldrich syndrome proteins (WASL, WASF2) as well as actin related protein 2/3 complex (ARPC2, ARPC3) and cofilin (CFL1). Variability in F-actin content between subjects was high; reduced actin content was only reduced within group evaluation. Reduced cytoskeleton-associated gene expression after n-3 PUFA supplementation suggests that regulation of cytoskeleton dynamics might be an additional way by which n-3 PUFAs exert their cellular effects. Concerning F-actin, this analysis did not reveal unmistakable results impeding a generalized conclusion.

    Atrial fibrillation is a major risk factor for recurrent ischaemic stroke, but often remains undiagnosed in patients who have had an acute ischaemic stroke. Enhanced and prolonged Holter-electrocardiogram-monitoring might increase detection of atrial fibrillation. We therefore investigated whether enhanced and prolonged rhythm monitoring was better for detection of atrial fibrillation than standard care procedures in patients with acute ischaemic stroke. Find-AF randomised is an open-label randomised study done at four centres in Germany. We recruited patients with acute ischaemic stroke (symptoms for 7 days or less) aged 60 years or older presenting with sinus rhythm and without history of atrial fibrillation. Patients were included irrespective of the suspected cause of stroke, unless they had a severe ipsilateral carotid or intracranial artery stenosis, which were the exclusion criteria. We used a computer-generated allocation sequence to randomly assign patients in a 1:1 ratio with permuted block sizes of 2, 4, 6, and 8, stratified by centre, to enhanced and prolonged monitoring (ie, 10-day Holter-electrocardiogram [ECG]-monitoring at baseline, and at 3 months and 6 months of follow-up) or standard care procedures (ie, at least 24 h of rhythm monitoring). Participants and study physicians were not masked to group assignment, but the expert committees that adjudicated endpoints were. The primary endpoint was the occurrence of atrial fibrillation or atrial flutter (30 sec or longer) within 6 months after randomisation and before stroke recurrence. Because Holter ECG is a widely used procedure and not known to harm patients, we chose not to assess safety in detail. Analysis was by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT01855035. Between May 8, 2013, and Aug 31, 2014, we recruited 398 patients. 200 patients were randomly assigned to the enhanced and prolonged monitoring group and 198 to the standard care group. After 6

Patients received PRM nightly, followed by a 2-week withdrawal period. Main outcome measures were patient-reported sleep quality ratings (diary, adverse events, vital signs, and laboratory tests recorded at each visit, and withdrawal symptoms (CHESS-84 [Check-list Evaluation of Somatic Symptoms]. Nocturnal urinary 6-sulfatoxymelatonin excretion, a measure of the endogenous melatonin production, was assessed upon discontinuing long-term PRM.Results: Of the 244 patients, 36 dropped out, 112 completed 6 months of treatment, and the other 96 completed 12 months of treatment. The mean number of nights by which patients reported sleep quality as "good" or "very good" was significantly higher during PRM than before treatment. There was no evidence of tolerance to PRM. Discontinuation of PRM was not associated with rebound insomnia or withdrawal symptoms; on the contrary, residual benefit was observed. PRM was well tolerated, and there was no suppression of endogenous melatonin production

    We examined whether 0.9 mg/day liraglutide plus basal insulin (Lira-basal) is superior to basal-bolus insulin therapy (BBIT) for type 2 diabetes (T2DM) without severe insulin deficiency as determined by glucagon stimulation. Fifty patients receiving BBIT were enrolled in this 24-week, prospective, randomized, open-labeled study. After excluding subjects with fasting C-peptide immunoreactivity (CPR) basal (n = 12) or continued BBIT (n = 13). Primary endpoint was change in HbA1c. Secondary endpoints were changes in body weight (BW), 7-point self-monitored blood glucose (SMBG), and Diabetes Treatment Satisfaction Questionnaire status (DTSQs) scores. The Lira-basal group demonstrated reduced HbA1c, whereas the BBIT group showed no change. BW was reduced in the Lira-basal group but increased in the BBIT group. The Lira-basal group also exhibited significantly reduced pre-breakfast and pre-lunch SMBG. DTSQs scores improved in the Lira-basal group but not the BBIT group. Plasma lipids, liver function, and kidney function were not significantly changed in either group. Lira-basal therapy is superior to BBIT for T2DM without severe insulin deficiency.

    Standardized neurofeedback (NF) protocols have been extensively evaluated in attention-deficit/hyperactivity disorder (ADHD). However, such protocols do not account for the large EEG heterogeneity in ADHD. Thus, individualized approaches have been suggested to improve the clinical outcome. In this direction, an open-label pilot study was designed to evaluate a NF protocol of relative upper alpha power enhancement in fronto-central sites. Upper alpha band was individually determined using the alpha peak frequency as an anchor point. 20 ADHD children underwent 18 training sessions. Clinical and neurophysiological variables were measured pre- and post-training. EEG was recorded pre- and post-training, and pre- and post-training trials within each session, in both eyes closed resting state and eyes open task-related activity. A power EEG analysis assessed long-term and within-session effects, in the trained parameter and in all the sensors in the (1-30) Hz spectral range. Learning curves over sessions were assessed as well. Parents rated a clinical improvement in children regarding inattention and hyperactivity/impulsivity. Neurophysiological tests showed an improvement in working memory, concentration and impulsivity (decreased number of commission errors in a continuous performance test). Relative and absolute upper alpha power showed long-term enhancement in task-related activity, and a positive learning curve over sessions. The analysis of within-session effects showed a power decrease ("rebound" effect) in task-related activity, with no significant effects during training trials. We conclude that the enhancement of the individual upper alpha power is effective in improving several measures of clinical outcome and cognitive performance in ADHD. This is the first NF study evaluating such a protocol in ADHD. A controlled evaluation seems warranted due to the positive results obtained in the current study.

    Freezing of gait is a disabling symptom in advanced Parkinson's disease. Positive effects have been suggested with MAO-B inhibitors. We report on an open label clinical study on the efficacy of rasagiline as add-on therapy on freezing of gait and quality of life in patients with Parkinson's disease. Forty two patients with freezing of gait were treated with 1 mg rasagiline daily as an add-on therapy. Patients were assessed at baseline and after 1, 2 and 3 months of treatment. Freezing of gait severity was assessed using the Freezing of Gait Questionnaire, motor impairment by the modified MDS UPDRS part III, and quality of life using the PDQ-39 questionnaire. Patients treated with rasagiline had a statistically significant decrease in FoG-Q score and modified MDS UPDRS score after 1, 2 and 3 months of therapy. A moderately strong (r = 0.686, P = 0.002) correlation between the effects on mobility and freezing of gait was found. We also observed a statistically significant improvement in global QoL and in the subscales mobility, ADL, stigma and bodily discomfort in patients after 3 months of rasagiline therapy. A significant correlation (r = 0.570, P = 0.02) between baseline FoG-Q score and the baseline score for the PDQ Mobility subscale was found. In our study rasagiline as add-on antiparkinsonian therapy significantly improved mobility, freezing of gait and quality of life. The positive effect on freezing of gait appears to be related to improvement of mobility.

    We aimed to explore the longer-term efficacy and safety of edaravone in an active-treatment extension period following the double-blind period of the second phase III study. Patients who met all the following criteria (scores ≥2 points on all 12 items of the revised amyotrophic lateral sclerosis functional rating scale [ALSFRS-R], forced vital capacity ≥80%, definite or probable ALS, and disease duration ≤2 years) were randomised to 60 mg intravenous edaravone or placebo for six cycles in the double-blind period, and then offered the opportunity to proceed to this 24-week open-label extension period. One hundred and twenty-three of 137 patients continued to the extension period: 65 edaravone-edaravone (E-E group) and 58 placebo-edaravone (P-E group). Change (mean ± standard deviation; SD) in the ALSFRS-R score from baseline in the double-blind period was -4.1 ± 3.4 and -6.9 ± 5.1 in the E-E group and P-E group, respectively, while it was -8.0 ± 5.6 in the E-E group and -10.9 ± 6.9 in the P-E group over the whole 48-week period. The ALSFRS-R score changed almost linearly throughout Cycles 1-12 in the E-E group. The most commonly reported adverse events were constipation, dysphagia, and contusion. There was no sudden deterioration in the ALSFRS-R score of the E-E group. No safety concerns related to edaravone were detected.

    This open-label trial assessed the clinical efficacy of L-5-hydroxytryptophan (5-HTP), a natural serotonin precursor, in nondepressed young subjects with high levels of romantic stress. Since both neurotrophins and serotonin have been linked to human romantic attachment, we sought to investigate the changes in serum brain-derived neurotrophic factor (BDNF) levels and platelet serotonin content in relation to the changes in romantic stress throughout the study. A total of 15 healthy subjects (11 females and 4 males, mean age: 23.3 ± 2.1 years) who experienced a recent romantic break-up or reported recent romantic problems took part in the study. The participants were treated openly for 6 weeks with L-5-hydroxytryptophan (60 mg Griffonia simplicifolia extract containing 12.8 mg 5-HTP b.i.d., Amorex, Coropharm, Villach, Austria). The subjects were evaluated at baseline, at 3 weeks and at the end of the 6-week trial using an adapted version of the Seiffge-Krenke's Problem Questionnaire. BDNF and platelet serotonin content were determined at baseline, at 3 weeks, and after the completion of the 6-week trial. We observed significant improvements in romantic stress scores from weeks 0 through 3 (p=0.007) but no further significant improvement was evident from weeks 3 through 6 (p=0.19). At 6 weeks, subjects had a significant increase from baseline in both BDNF and platelet serotonin values. Our data suggest that direct modulation of the serotonergic system may have use for the treatment of psychological suffering associated with unreciprocated romantic love.

The primary objective of this open-label exploratory study was to investigate the analgesic effectiveness of pulsed electromagnetic field therapy administered twice daily over a 45-day period in 34 subjects (68% female with persistent or recurrent pain following back surgery. A secondary goal was to guide the design of future randomized controlled trials that could target responsive subpopulations. All predefined primary and secondary outcomes, including change in pain intensity (PI, physical function (Oswestry Disability Index, analgesic consumption, and overall well-being (Patient Global Impression of Change, are reported. A responder analysis (≥30% reduction in PI versus baseline was added as a post hoc evaluation. Safety outcomes, as well as results of a cost-avoidance survey, are also summarized. Of the 30 per-protocol subjects who completed the study, 33% reported a clinically meaningful (≥30% reduction in PI. A higher response rate (60% was reported for subjects who had undergone discectomy prior to the trial compared to subjects who had undergone other types of surgical interventions (decompression or fusion without discectomy. Improvements in PI were paralleled by improvements in secondary outcomes. Relative to baseline, responders reported an average 44% and 55% reduction in back PI and leg PI (respectively, and an average 13% improvement in Oswestry Disability Index scores. In the per-protocol population, 50% of responders and 12% of nonresponders reported less analgesia consumption at the end of treatment versus baseline.

    [18F]2-fluoro-2-deoxy-d-glucose positron emission tomography/computed tomography (18FDG-PET/CT) has high sensitivity for detecting recurrences of colorectal cancer (CRC). Our objective was to determine whether adding routine 6-monthly 18FDG-PET/CT to our usual monitoring strategy improved patient outcomes and to assess the effect on costs. In this open-label multicentre trial, patients in remission of CRC (stage II perforated, stage III, or stage IV) after curative surgery were randomly assigned (1 : 1) to usual monitoring alone (3-monthly physical and tumour marker assays, 6-monthly liver ultrasound and chest radiograph, and 6-monthly whole-body computed tomography) or with 6-monthly 18FDG-PET/CT, for 3 years. A multidisciplinary committee reviewed each patient's data every 3 months and classified the recurrence status as yes/no/doubtful. Recurrences were treated with curative surgery alone if feasible and with chemotherapy otherwise. The primary end point was treatment failure defined as unresectable recurrence or death. Relative risks were estimated, and survival was analysed using the Kaplan-Meier method, log-rank test, and Cox models. Direct costs were compared. Of the 239 enrolled patients, 120 were in the intervention arm and 119 in the control arm. The failure rate was 29.2% (31 unresectable recurrences and 4 deaths) in the intervention group and 23.7% (27 unresectable recurrences and 1 death) in the control group (relative risk = 1.23; 95% confidence interval, 0.80-1.88; P = 0.34). The multivariate analysis also showed no significant difference (hazards ratio, 1.33; 95% confidence interval, 0.8-2.19; P = 0.27). Median time to diagnosis of unresectable recurrence (months) was significantly shorter in the intervention group [7 (3-20) versus 14.3 (7.3-27), P = 0.016]. Mean cost/patient was higher in the intervention group (18 192 ± 27 679 € versus 11 131 ± 13  €, P CRC. The control group had very close follow

KG, Karlsruhe, Germany Purpose: This study is the first clinical trial aiming to explore the clinical outcomes in burnout patients treated with Rhodiola rosea. The reported capacity of R. rosea to strengthen the organism against stress and its good tolerability offer a promising approach in the treatment of stress-related burnout. The aim of the treatment was to increase stress resistance, thus addressing the source rather than the symptoms of the syndrome and preventing subsequent diseases associated with a history of burnout. The objective of the trial was to provide the exploratory data required for planning future randomized trials in burnout patients in order to investigate the clinical outcomes of treatment with R. rosea dry extract in this target group.Methods: The study was planned as an exploratory, open-label, multicenter, single-arm trial. A wide range of rating scales were assessed and evaluated in an exploratory data analysis to generate hypotheses regarding clinical courses and to provide a basis for the planning of subsequent studies. A total of 118 outpatients were enrolled. A daily dose of 400 mg R. rosea extract (WS® 1375, Rosalin was administered over 12 weeks. Clinical outcomes were assessed by the German version of the Maslach Burnout Inventory, Burnout Screening Scales I and II, Sheehan Disability Scale, Perceived Stress Questionnaire, Number Connection Test, Multidimensional Mood State Questionnaire, Numerical Analogue Scales for different stress symptoms and impairment of sexual life, Patient Sexual Function Questionnaire, and the Clinical Global Impression Scales.

    Reirradiation is a potentially useful option for many patients with recurrent cancer. The purpose of this study was to review all recently published randomized trials in order to identify methodological strengths and weaknesses, comment on the results, clinical implications and open questions, and give advice for the planning of future trials. Systematic review of trials published between 2000 and 2015 (databases searched were PubMed, Scopus and Web of Science). We reviewed 9 trials, most of which addressed reirradiation of head and neck tumours. The median number of patients was 69. Trial design, primary endpoint and statistical hypotheses varied widely. The results contribute mainly to decision making for reirradiation of nasopharynx cancer and bone metastases. The trials with relatively long median follow-up confirm that serious toxicity remains a concern after high cumulative total doses. Multi-institutional collaboration is encouraged to complete sufficiently large trials. Despite a paucity of large randomized studies, reirradiation has been adopted in different clinical scenarios by many institutions. Typically, the patients have been assessed by multidisciplinary tumour boards and advanced technologies are used to create highly conformal dose distributions. (orig.) [de

    Rationale A number of randomized trials are underway, which will address the effects of angiotensin receptor blockers (ARBs) on aortic root enlargement and a range of other end points in patients with Marfan syndrome. If individual participant data from these trials were to be combined, a meta-analysis of the resulting data, totaling approximately 2,300 patients, would allow estimation across a number of trials of the treatment effects both of ARB therapy and of β-blockade. Such an analysis would also allow estimation of treatment effects in particular subgroups of patients on a range of end points of interest and would allow a more powerful estimate of the effects of these treatments on a composite end point of several clinical outcomes than would be available from any individual trial. Design A prospective, collaborative meta-analysis based on individual patient data from all randomized trials in Marfan syndrome of (i) ARBs versus placebo (or open-label control) and (ii) ARBs versus β-blockers will be performed. A prospective study design, in which the principal hypotheses, trial eligibility criteria, analyses, and methods are specified in advance of the unblinding of the component trials, will help to limit bias owing to data-dependent emphasis on the results of particular trials. The use of individual patient data will allow for analysis of the effects of ARBs in particular patient subgroups and for time-to-event analysis for clinical outcomes. The meta-analysis protocol summarized in this report was written on behalf of the Marfan Treatment Trialists' Collaboration and finalized in late 2012, without foreknowledge of the results of any component trial, and will be made available online (http://www.ctsu.ox.ac.uk/research/meta-trials).

    Full Text Available We report a prospective, open-label, randomized study to evaluate the safety and efficacy of converting patients with a stable renal function from tacrolimus (Tac-based regimen to a sirolimus (SRL-based regimen after kidney transplantation. Fifty-eight low-risk renal allograft recipients who receiving Tac 6 months posttransplant, were randomly assigned to continue Tac (n = 29 or convert to SRL (n = 29. We evaluated the 3-year outcomes including patient and graft survival, graft function, and safety profile. Three-year patient and graft survival in SRL and Tac groups were 93.1% versus 100% (P = 0.32, and 89.7% versus 100% (P = 0.11, respectively. However, the SRL group had a significantly better renal function, from the 2nd year posttransplant until the last follow-up. Four (13.8% patients in the SRL group and 3 (10.3% in the Tac group (P = 0.5 developed biopsy-proven acute rejection. Mean urinary protein excretion increased significantly after SRL conversion. Diastolic blood pressure was significantly lower at the end of the study in patients who eliminated Tac (80.4 vs. 75.6 mmHg in Tac and SRL group, respectively (P = 0.03. Mean hemoglobin concentrations decreased after SRL conversion and remained significantly lower from 12 months to 36 months (P = 0.01. The mean serum cholesterol (540 ± 44 mg/dl and triglyceride (177 ± 27 mg/dl increased significantly in the SRL group, compared to Tac group (487 ± 62 mg/dl (P = 0.03 and (141 ± 26 mg/dl (P = 0.04. Our experience demonstrates that conversion to SRL from calcineurin inhibitors-based therapy may result in better renal function and blood pressure control in renal transplant recipients without an increased risk of acute rejection. However, these benefits have not resulted in a growing advantage in graft or patient survival.

    To evaluate in a comprehensive way TVT in comparison with TOT, the results of a single-center RCT are presented. Many studies addressed efficacy and safety of TVT and TOT. Women included were adults having predominant SUI with positive stress test. They were randomized to get either TVT (Gynecare(®)) or TOT (Aris(®)). All women were seen 1 week, 3, 6, 12, 18, and 24 months. Seventy-one women completed 2-year follow-up. Median age was 47 (range 33-60 years). Mean ± SD BMI in TVT group was 34 ± 5 while in TOT group was 32 ± 5 kg/m(2). POP of any degree was seen in 50 % (35 women). At 1 year, pad test-negative women were 31 and 29 for TVT and TOT, respectively. At 2 years, figures became 28 in TVT group and 27 in TOT. At 1 year, UDI 6 and IIQ 7 decreased by 78.5 and 81 % for TVT and by 69 % and 75 % for TOT group. At 2 year, comparable percentages were 73 and 79 % for TVT and 69 and 82 % for TOT. Fifteen unique patients had adverse events, 10 of them had TOT. Both tapes have similar efficacy, regarding cure of incontinence. TVT is more effective, albeit insignificantly, than TOT at 2 years. However, serious adverse events were more frequent with TVT, yet TOT has more unique adverse events.

    Arthroscopic education research recently has been focused on the use of skills labs to facilitate resident education and objective measure development to gauge technical skill. This study evaluates the effectiveness of three different teaching methods. Medical students were randomized into three groups. The first group received only classroom-based lecture. The second group received the same lecture and 28 minutes of lab-based hands-off arthroscopy instruction using a cadaver and arthroscopy setup. The final group received the same lecture and 7 minutes of hands-on arthroscopy instruction in the lab on a cadaver knee. The arthroscopic knee exam that followed simulated a diagnostic knee exam and subjects were measured on task completion and by the number of look downs. The number of look downs and the number of tasks completed did not achieve statistical significance between groups. Posttest survey results revealed that the hands-on group placed significantly more value on their educational experience as compared with the other two groups.

    Full Text Available Preliminary in vitro and in vivo studies with valproic acid (VPA in cell lines and patients with spinal muscular atrophy (SMA demonstrate increased expression of SMN, supporting the possibility of therapeutic benefit. We performed an open label trial of VPA in 42 subjects with SMA to assess safety and explore potential outcome measures to help guide design of future controlled clinical trials. Subjects included 2 SMA type I ages 2-3 years, 29 SMA type II ages 2-14 years and 11 type III ages 2-31 years, recruited from a natural history study. VPA was well-tolerated and without evident hepatotoxicity. Carnitine depletion was frequent and temporally associated with increased weakness in two subjects. Exploratory outcome measures included assessment of gross motor function via the modified Hammersmith Functional Motor Scale (MHFMS, electrophysiologic measures of innervation including maximum ulnar compound muscle action potential (CMAP amplitudes and motor unit number estimation (MUNE, body composition and bone density via dual-energy X-ray absorptiometry (DEXA, and quantitative blood SMN mRNA levels. Clear decline in motor function occurred in several subjects in association with weight gain; mean fat mass increased without a corresponding increase in lean mass. We observed an increased mean score on the MHFMS scale in 27 subjects with SMA type II (p

    Psilocybin is a serotonin receptor agonist that occurs naturally in some mushroom species. Recent studies have assessed the therapeutic potential of psilocybin for various conditions, including end-of-life anxiety, obsessive-compulsive disorder, and smoking and alcohol dependence, with promising preliminary results. Here, we aimed to investigate the feasibility, safety, and efficacy of psilocybin in patients with unipolar treatment-resistant depression. In this open-label feasibility trial, 12 patients (six men, six women) with moderate-to-severe, unipolar, treatment-resistant major depression received two oral doses of psilocybin (10 mg and 25 mg, 7 days apart) in a supportive setting. There was no control group. Psychological support was provided before, during, and after each session. The primary outcome measure for feasibility was patient-reported intensity of psilocybin's effects. Patients were monitored for adverse reactions during the dosing sessions and subsequent clinic and remote follow-up. Depressive symptoms were assessed with standard assessments from 1 week to 3 months after treatment, with the 16-item Quick Inventory of Depressive Symptoms (QIDS) serving as the primary efficacy outcome. This trial is registered with ISRCTN, number ISRCTN14426797. Psilocybin's acute psychedelic effects typically became detectable 30-60 min after dosing, peaked 2-3 h after dosing, and subsided to negligible levels at least 6 h after dosing. Mean self-rated intensity (on a 0-1 scale) was 0·51 (SD 0·36) for the low-dose session and 0·75 (SD 0·27) for the high-dose session. Psilocybin was well tolerated by all of the patients, and no serious or unexpected adverse events occurred. The adverse reactions we noted were transient anxiety during drug onset (all patients), transient confusion or thought disorder (nine patients), mild and transient nausea (four patients), and transient headache (four patients). Relative to baseline, depressive symptoms were markedly reduced 1

    Stroke is one of the most common causes of death and few pharmacological therapies show benefits in ischemic stroke. In this study, 290 patients aged 40-75 years old with first onset of acute ischemic stroke (more than 24 hours but within 14 days) were treated with standard treatments, and then were randomly allocated into an intervention group (treated with resuscitating acupuncture) and a control group (treated using sham-acupoints). Primary outcome measures included Barthel Index (BI), relapse and death up to six months. For the 290 patients in both groups, one case in the intervention group died, and two cases in the control group died from the disease (p = 0.558). Six patients of the 144 cases in the intervention group had relapse, whereas 34 of 143 patients had relapse in the control group (p two groups, respectively (p two groups for the National Institute of Health Stroke Scale (NIHSS), not at two weeks (7.03 ± 3.201 vs. 8.13 ± 3.634; p = 0.067), but at four weeks (4.15 ± 2.032 vs. 6.35 ± 3.131, p Stroke Scale (CSS) at four weeks showed more improvement in the intervention group than that in the control group (9.40 ± 4.51 vs. 13.09 ± 5.80, p Stroke Specific Quality of Life Scale (SS-QOL) at six months was higher in the intervention group (166.63 ± 45.70) than the control group (143.60 ± 50.24; p < 0.01). The results of this clinical trial showed a clinically relevant decrease of relapse in patients treated with resuscitating acupuncture intervention by the end of six months, compared with needling at the sham-acupoints. The resuscitating acupuncture intervention could also improve self-care ability and quality of life, evaluated with BI, NIHSS, CSS, Oxford Handicap Scale (OHS), and SS-QOL.

    To compare the effectiveness of a mixture of acacia fiber, psyllium fiber, and fructose (AFPFF) with polyethylene glycol 3350 combined with electrolytes (PEG+E) in the treatment of children with chronic functional constipation (CFC); and to evaluate the safety and effectiveness of AFPFF in the treatment of children with CFC. This was a randomized, open label, prospective, controlled, parallel-group study involving 100 children (M/F: 38/62; mean age ± SD: 6.5 ± 2.7 years) who were diagnosed with CFC according to the Rome III Criteria. Children were randomly divided into 2 groups: 50 children received AFPFF (16.8 g daily) and 50 children received PEG+E (0.5 g/kg daily) for 8 weeks. Primary outcome measures were frequency of bowel movements, stool consistency, fecal incontinence, and improvement of other associated gastrointestinal symptoms. Safety was assessed with evaluation of clinical adverse effects and growth measurements. Compliance rates were 72% for AFPFF and 96% for PEG+E. A significant improvement of constipation was seen in both groups. After 8 weeks, 77.8% of children treated with AFPFF and 83% of children treated with PEG+E had improved (P = .788). Neither PEG+E nor AFPFF caused any clinically significant side effects during the entire course of the study period. In this randomized study, we did not find any significant difference between the efficacy of AFPFF and PEG+E in the treatment of children with CFC. Both medications were proved to be safe for CFC treatment, but PEG+E was better accepted by children. Copyright © 2012 Mosby, Inc. All rights reserved.

    The purpose of this study was to assess the midterm results of total knee arthroplasty (TKA) implanted with a specific computer navigation system in a group of patients (NAV) and to assess the same prosthesis implanted with the conventional technique in another group (CON); we hypothesized that computer navigation surgery would improve implant alignment, functional scores and survival of the implant compared to the conventional technique. From 2008 to 2009, 225 patients were enrolled in the study and randomly assigned in CON and NAV groups; 240 consecutive mobile-bearing ultra-congruent score (Amplitude, Valence, France) TKAs were performed by a single surgeon, 117 using the conventional method and 123 using the computer-navigated approach. Clinical outcome assessment was based on the Knee Society Score (KSS), the Hospital for Special Surgery Knee Score and the Western Ontario Mac Master University Index score. Component survival was calculated by Kaplan-Meier analysis. Median follow-up was 6.4 years (range 6-7 years). Two patients were lost to follow-up. No differences were seen between the two groups in age, sex, BMI and side of implantation. Three patients of CON group referred feelings of instability during walking, but clinical tests were all negative. NAV group showed statistical significant better KSS Score and wider ROM and fewer outliers from neutral mechanical axis, lateral distal femoral angle, medial proximal tibial angle and tibial slope in post-operative radiographic assessment. There was one case of early post-operative superficial infection (caused by Staph. Aureus) successfully treated with antibiotics. No mechanical loosening, mobile-bearing dislocation or patellofemoral complication was seen. At 7 years of follow-up, component survival in relation to the risk of aseptic loosening or other complications was 100 %. There were no implant revisions. This study demonstrates superior accuracy in implant positioning and statistical significant

    Full Text Available Natalizumab is an effective therapy for multiple sclerosis (MS. Its effectiveness has been demonstrated in several clinical and imaging studies. The objective of this study was to further demonstrate the efficacy of natalizumab using a comprehensive battery of clinical and imaging markers in the same cohort of patients followed longitudinally, hence capturing the multi-faceted nature of the MS disease process. A prospective, open-label, pilot study of 20 MS patients treated with natalizumab was conducted. High resolution MRI, Symbol-Digit Modalities Test (SDMT, and Optical Coherence Tomography (OCT scans were obtained at baseline, 48, and 96 weeks. 15 patients completed the study. Natalizumab treatment decreased Expanded Disability Status Scale score (EDSS and no change in SDMT, Brain Parenchymal Fraction (BPF, or any of the OCT markers of retinal degeneration was observed. Thalamic and whole brain volume as assessed by Percentage Brain Volume Change (PBVC showed continuous deterioration. Higher baseline T2 lesion load correlated with increased rate of PBVC at 96-weeks (r = 0.566, R2 = 0.320, p = 0.035 and thalamic volume loss (r = -0.586, R2 = 0.344, p = 0.027. Most patients, 93%, achieved no evidence of disease activity (NEDA at 2 years, likely due to early disease duration and lower initial baseline lesion load. This study further demonstrates stabilization of clinical and imaging markers of disease activity during natalizumab treatment.

    Influenza causes substantial morbidity and mortality despite available treatments. Anecdotal reports suggest that plasma with high antibody titres to influenza might be of benefit in the treatment of severe influenza. In this randomised, open-label, multicentre, phase 2 trial, 29 academic medical centres in the USA assessed the safety and efficacy of anti-influenza plasma with haemagglutination inhibition antibody titres of 1:80 or more to the infecting strain. Hospitalised children and adults (including pregnant women) with severe influenza A or B (defined as the presence of hypoxia or tachypnoea) were randomly assigned to receive either two units (or paediatric equivalent) of anti-influenza plasma plus standard care, versus standard care alone, and were followed up for 28 days. The primary endpoint was time to normalisation of patients' respiratory status (respiratory rate of ≤20 breaths per min for adults or age-defined thresholds of 20-38 breaths per min for children) and a room air oxygen saturation of 93% or more. This study is registered with ClinicalTrials.gov, number NCT01052480. Between Jan 13, 2011, and March 2, 2015, 113 participants were screened for eligibility and 98 were randomly assigned from 20 out of 29 participating sites. Of the participants with confirmed influenza (by PCR), 28 (67%) of 42 in the plasma plus standard care group normalised their respiratory status by day 28 compared with 24 (53%) of 45 participants on standard care alone (p=0·069). The hazard ratio (HR) comparing plasma plus standard care with standard care alone was 1·71 (95% CI 0·96-3·06). Six participants died, one (2%) from the plasma plus standard care group and five (10%) from the standard care group (HR 0·19 [95% CI 0·02-1·65], p=0·093). Participants in the plasma plus standard care group had non-significant reductions in days in hospital (median 6 days [IQR 4-16] vs 11 days [5-25], p=0·13) and days on mechanical ventilation (median 0 days [IQR 0-6] vs 3 days

Patients and methods: Participants (n = 12, five females [mean age, 62 ± 11.06 years] and seven males [mean age, 57.14 ± 9.20 years] with a confirmed diagnosis of osteoarthritis of the knee were randomized to either 100 mg (n = 5 or 1000 mg (n = 7 of a Maritech® extract formulation per day. The formulation contained Maritech® seaweed extract containing Fucus vesiculosis (85% w/w, Macrocystis pyrifera (10% w/w and Laminaria japonica (5% w/w plus vitamin B6, zinc and manganese. Primary outcome was the average comprehensive arthritis test (COAT score which is comprised of four sub-scales: pain, stiffness, difficulty with physical activity and overall symptom severity measured weekly. Safety measures included full blood count, serum lipids, liver function tests, urea, creatinine and electrolytes determined at baseline and week 12. All adverse events were recorded.Results: Eleven participants completed 12 weeks and one completed 10 weeks of the study. Using a multilevel linear model, the average COAT score was reduced by 18% for the 100 mg treatment and 52% for the 1000 mg dose at the end of the study. There was a clear dose response effect

    Transfusion thresholds for acute upper gastrointestinal bleeding are controversial. So far, only three small, underpowered studies and one single-centre trial have been done. Findings from the single-centre trial showed reduced mortality with restrictive red blood cell (RBC) transfusion. We aimed to assess whether a multicentre, cluster randomised trial is a feasible method to substantiate or refute this finding. In this pragmatic, open-label, cluster randomised feasibility trial, done in six university hospitals in the UK, we enrolled all patients aged 18 years or older with new presentations of acute upper gastrointestinal bleeding, irrespective of comorbidity, except for exsanguinating haemorrhage. We randomly assigned hospitals (1:1) with a computer-generated randomisation sequence (random permuted block size of 6, without stratification or matching) to either a restrictive (transfusion when haemoglobin concentration fell below 80 g/L) or liberal (transfusion when haemoglobin concentration fell below 100 g/L) RBC transfusion policy. Neither patients nor investigators were masked to treatment allocation. Feasibility outcomes were recruitment rate, protocol adherence, haemoglobin concentration, RBC exposure, selection bias, and information to guide design and economic evaluation of the phase 3 trial. Main exploratory clinical outcomes were further bleeding and mortality at day 28. We did analyses on all enrolled patients for whom an outcome was available. This trial is registered, ISRCTN85757829 and NCT02105532. Between Sept 3, 2012, and March 1, 2013, we enrolled 936 patients across six hospitals (403 patients in three hospitals with a restrictive policy and 533 patients in three hospitals with a liberal policy). Recruitment rate was significantly higher for the liberal than for the restrictive policy (62% vs 55%; p=0·04). Despite some baseline imbalances, Rockall and Blatchford risk scores were identical between policies. Protocol adherence was 96% (SD 10) in

    Ponatinib has shown potent activity against chronic myeloid leukaemia that is resistant to available treatment, although it is associated with arterial occlusion. We investigated whether this activity and safety profile would result in superior outcomes compared with imatinib in previously untreated patients with chronic myeloid leukaemia. The Evaluation of Ponatinib versus Imatinib in Chronic Myeloid Leukemia (EPIC) study was a randomised, open-label, phase 3 trial designed to assess the efficacy and safety of ponatinib, compared with imatinib, in newly diagnosed patients with chronic-phase chronic myeloid leukaemia. Patients from 106 centres in 21 countries were randomly assigned (1:1, with stratification by Sokal score at diagnosis) using an interactive voice and web response system to receive oral ponatinib (45 mg) or imatinib (400 mg) once daily until progression, unacceptable toxicity, or other criteria for withdrawal were met. Eligible patients were at least 18 years of age, within 6 months of diagnosis, and Philadelphia chromosome-positive by cytogenetic assessment, with Eastern Cooperative Oncology Group performance status of 0-2, and had not previously been treated with tyrosine kinase inhibitors. The primary endpoint was major molecular response at 12 months. Patients who remained on study and had molecular assessments at specified timepoints were studied at those timepoints. Safety analyses included all treated patients, as per study protocol. This trial is registered with ClinicalTrials.gov, number NCT01650805. Between Aug 14, 2012, and Oct 9, 2013, 307 patients were randomly assigned to receive ponatinib (n=155) or imatinib (n=152). The trial was terminated early, on Oct 17, 2013, following concerns about vascular adverse events observed in patients given ponatinib in other trials. Trial termination limited assessment of the primary endpoint of major molecular response at 12 months, as only 13 patients in the imatinib group and ten patients in the

    Somatostatin analogues (SSAs) are indicated to relieve carcinoid syndrome but seem to have antiproliferative effects on neuroendocrine tumours (NETs). This is the first prospective study investigating tumour stabilisation with the long-acting SSA lanreotide Autogel in patients with progressive NETs. This was a multicentre, open-label, phase II trial conducted in 17 Spanish specialist centres. Patients with well-differentiated NETs and radiologically confirmed progression within the previous 6 months received lanreotide Autogel, 120 mg every 28 days over ≤92 weeks. The primary endpoint was progression-free survival (PFS). Secondary endpoints were response rate, tumour biomarkers, symptom control, quality of life (QoL), and safety. Radiographic imaging was assessed by a blinded central radiologist. Of 30 patients included in the efficacy and safety analyses, 40% had midgut tumours and 27% pancreatic tumours; 63% of tumours were functioning. Median PFS time was 12.9 (95% CI: 7.9, 16.5) months, and most patients achieved disease stabilisation (89%) or partial response (4%). No deterioration in QoL was observed. Nineteen patients (63%) experienced treatment-related adverse events, most frequently diarrhoea and asthenia; only one treatment-related adverse event (aerophagia) was severe. Lanreotide Autogel provided effective tumour stabilisation and PFS >12 months in patients with progressive NETs ineligible for surgery or chemotherapy, with a safety profile consistent with the pharmacology of the class.

    The efficacy of low-dose lansoprazole has not been established for the prevention of recurrent gastric or duodenal ulcers in those receiving long-term low-dose aspirin (LDA) for cardiovascular and cerebrovascular protection. This study sought to examine the efficacy of low-dose lansoprazole (15 mg once daily) for the secondary prevention of LDA-associated gastric or duodenal ulcers. Patients were randomized to receive lansoprazole 15 mg daily (n = 226) or gefarnate 50 mg twice daily (n = 235) for 12 months or longer in a prospective, multicenter, double-blind, randomized active-controlled trial, followed by a 6-month follow-up study with open-label lansoprazole treatment. The study utilized 94 sites in Japan and 461 Japanese patients with a history of gastric or duodenal ulcers who required long-term LDA therapy for cardiovascular and cerebrovascular disease. The primary endpoint was the development of gastric or duodenal ulcers. The cumulative incidence of gastric or duodenal ulcers on days 91, 181, and 361 from the start of the study was calculated by the Kaplan-Meier method as 1.5, 2.1, and 3.7%, respectively, in the lansoprazole group versus 15.2, 24.0, and 31.7%, respectively, in the gefarnate group. The risk of ulcer development was significantly (log-rank test, P lansoprazole group than in the gefarnate group, with the hazard ratio being 0.099 (95% confidence interval [CI] 0.042-0.230). Lansoprazole was superior to gefarnate in reducing the risk of gastric or duodenal ulcer recurrence in patients with a definite history of gastric or duodenal ulcers who required long-term LDA therapy.

    To study the efficacy of alendronate, in the treatment of avascular necrosis (AVN) of the hip. Sixty patients with AVN of the hip (100 hips with AVN) were studied. The follow-up period ranged from 3 months to 5 yr. The most common cause of AVN was steroids. Parameters studied were walking time, standing time, pain and disability on a visual analogue scale (VAS), range of motion of the hip, X-ray and MRI of the hip. All patients were treated with alendronate 10 mg/day (or 70 mg/week) along with 500-1000 mg of daily calcium and vitamin D supplements, and were advised to avoid weight-bearing. NSAIDs and analgesics were permitted as needed and were recorded. Forty-one patients (71 AVN hips) with AVN have been followed up for a minimum of 1 yr, 24 patients (42 AVN hips) for 2 yr and 21 patients (37 AVN hips) for more than 2 yr (average 37 month). Fourteen patients have been followed up for less than 1 yr (3-9 months). Significant reduction in pain and disability scores (P 0.001). Radiologically, the hips either stabilized in the same grade or progressed by one grade. MRI showed a decrease in marrow oedema in most cases at the 1-yr follow-up. Six patients (10 hips) required surgery and there were two (three hips) dropouts. The drug was well tolerated and there was a reduction in NSAID requirement. Alendronate reduces pain, improves function and retards AVN progression. Early surgical intervention can be avoided in most patients.

    Objectives We determined headache patients' satisfaction with telemedicine and assessed how telemedicine influenced headache burden, compliance with diagnosis and treatment, and need for follow-up consultations. Methods During 2.5 years, patients from Northern Norway referred with non-acute headaches for a specialist consultation at Tromsø University Hospital were consecutively randomised to either telemedicine or traditional visits. Baseline data were recorded and compared to data from a three-month follow-up questionnaire (see Supplementary material). The following were evaluated: (1) satisfaction with the consultation; (2) headache status; subjective improvement, average pain intensity, treatment, headache days per month, and Headache Impact Test (HIT-6); and (3) treatment compliance and follow-up visits. Results Out of 402 consultations, 348 (86.6%) answered the questionnaire. Satisfaction was similar in the telemedicine and the traditional group (88.8% vs. 92.3%; p = 0.35). Subgroup analyses were not prespecified, but there were no differences in satisfaction among females, migraineurs, rural patients and urban patients. Improvement from baseline after three months was reported equally in the telemedicine and the traditional groups. There were also no differences in treatment compliance, but rural telemedicine patients had less-frequent headache visits at three months' follow-up (28.9% vs. 48.7%, p = 0.002). Conclusion Telemedicine is non-inferior to traditional consultations in patient satisfaction, specialist evaluation, and treatment of non-acute headaches. ClinicalTrials.gov ID: NCT02270177.

    Because treatment with third-generation cephalosporins is associated with slow clinical improvement and high relapse burden for enteric fever, whereas the fluoroquinolone gatifloxacin is associated with rapid fever clearance and low relapse burden, we postulated that gatifloxacin would be superior to the cephalosporin ceftriaxone in treating enteric fever. We did an open-label, randomised, controlled, superiority trial at two hospitals in the Kathmandu valley, Nepal. Eligible participants were children (aged 2-13 years) and adult (aged 14-45 years) with criteria for suspected enteric fever (body temperature ≥38·0°C for ≥4 days without a focus of infection). We randomly assigned eligible patients (1:1) without stratification to 7 days of either oral gatifloxacin (10 mg/kg per day) or intravenous ceftriaxone (60 mg/kg up to 2 g per day for patients aged 2-13 years, or 2 g per day for patients aged ≥14 years). The randomisation list was computer-generated using blocks of four and six. The primary outcome was a composite of treatment failure, defined as the occurrence of at least one of the following: fever clearance time of more than 7 days after treatment initiation; the need for rescue treatment on day 8; microbiological failure (ie, blood cultures positive for Salmonella enterica serotype Typhi, or Paratyphi A, B, or C) on day 8; or relapse or disease-related complications within 28 days of treatment initiation. We did the analyses in the modified intention-to-treat population, and subpopulations with either confirmed blood-culture positivity, or blood-culture negativity. The trial was powered to detect an increase of 20% in the risk of failure. This trial was registered at ClinicalTrials.gov, number NCT01421693, and is now closed. Between Sept 18, 2011, and July 14, 2014, we screened 725 patients for eligibility. On July 14, 2014, the trial was stopped early by the data safety and monitoring board because S Typhi strains with high-level resistance to

    Conventional collar incision closure in thyroid and parathyroid surgery involves the insertion of an epidermal layer of subcutaneous absorbable sutures that are reinforced by a deep layer of sutures. Adhesive strips offer an alternative method to close the epidermal layer. The aim of this study was to compare adhesive strip closure with absorbable sutures for collar incisions in a prospective, single-blinded, randomized controlled trial.

    The phase 3 ENDEAVOR trial was a head-to-head comparison of two proteasome inhibitors in patients with relapsed or refractory multiple myeloma. Progression-free survival was previously reported to be significantly longer with carfilzomib administered in combination with dexamethasone than with bortezomib and dexamethasone in an interim analysis. The aim of this second interim analysis was to compare overall survival between the two treatment groups. ENDEAVOR was a phase 3, open-label, randomised controlled trial in patients with relapsed or refractory multiple myeloma. Patients were recruited from 198 hospitals and outpatient clinics in 27 countries in Europe, North America, South America, and the Asia-Pacific region. Patients were aged 18 years or older, had relapsed or refractory multiple myeloma, and had received between one and three previous lines of therapy. Patients were randomly assigned (1:1) to receive carfilzomib and dexamethasone (carfilzomib group) or bortezomib and dexamethasone (bortezomib group) through a blocked randomisation scheme (block size of four), stratified by International Staging System stage, previous lines of treatment, previous proteasome inhibitor therapy, and planned route of bortezomib delivery if assigned to the bortezomib group. Carfilzomib (20 mg/m 2 on days 1 and 2 of cycle 1; 56 mg/m 2 thereafter) was given as a 30-min intravenous infusion on days 1, 2, 8, 9, 15, and 16 of 28-day cycles; bortezomib (1·3 mg/m 2 ) was given as an intravenous bolus or subcutaneous injection on days 1, 4, 8, and 11 of 21-day cycles. Dexamethasone (20 mg oral or intravenous infusion) was given on days 1, 2, 8, 9, 15, 16, 22, and 23 in the carfilzomib group and on days 1, 2, 4, 5, 8, 9, 11, and 12 in the bortezomib group. The primary endpoint of ENDEAVOR, progression-free survival, has been previously reported. A stratified log-rank test was used to compare overall survival between treatment groups for this prospectively planned second interim

    Microbiological diagnosis (MD) of infections remains insufficient. The resulting empirical antimicrobial therapy leads to multidrug resistance and inappropriate treatments. We therefore evaluated the cost-effectiveness of direct molecular detection of pathogens in blood for patients with severe sepsis (SES), febrile neutropenia (FN) and suspected infective endocarditis (SIE). Patients were enrolled in a multicentre, open-label, cluster-randomised crossover trial conducted during two consecutive periods, randomly assigned as control period (CP; standard diagnostic workup) or intervention period (IP; additional testing with LightCycler ® SeptiFast). Multilevel models used to account for clustering were stratified by clinical setting (SES, FN, SIE). A total of 1416 patients (907 SES, 440 FN, 69 SIE) were evaluated for the primary endpoint (rate of blood MD). For SES patients, the MD rate was higher during IP than during CP [42.6% (198/465) vs. 28.1% (125/442), odds ratio (OR) 1.89, 95% confidence interval (CI) 1.43-2.50; P analysis of the incremental cost-effectiveness ratio showed weak dominance of intervention in SES patients. Addition of molecular detection to standard care improves MD and thus efficiency of healthcare resource usage in patients with SES. ClinicalTrials.gov registration number: NCT00709358.

    Objectives We investigated the clinical benefits of bright light therapy (BLT) as an adjunct treatment to ongoing psychopharmacotherapy, both in unipolar and bipolar difficult-to-treat depressed (DTD) outpatients. Methods In an open-label study, 31 depressed outpatients (16 unipolar and 15 bipolar) were included to undergo 3 weeks of BLT. Twenty-five completed the treatment and 5-week follow-up. Main outcome measures Clinical outcomes were evaluated by the Hamilton Depression Rating Scale (HDRS). The Snaith–Hamilton Pleasure Scale and the Depression Retardation Rating Scale were used to assess changes in anhedonia and psychomotor retardation, respectively. Results The adjunctive BLT seemed to influence the course of the depressive episode, and a statistically significant reduction in HDRS scores was reported since the first week of therapy. The treatment was well-tolerated, and no patients presented clinical signs of (hypo)manic switch during the overall treatment period. At the end of the study (after 5 weeks from BLT discontinuation), nine patients (36%, eight unipolar and one bipolar) still showed a treatment response. BLT augmentation also led to a significant improvement of psychomotor retardation. Conclusion BLT combined with the ongoing pharmacological treatment offers a simple approach, and it might be effective in rapidly ameliorating depressive core symptoms of vulnerable DTD outpatients. These preliminary results need to be confirmed in placebo-controlled, randomized, double-blind clinical trial on larger samples. PMID:26396517

    Full Text Available Background/Aims: In this post-marketing observational study, the safety and effectiveness of memantine were evaluated in patients with Alzheimer’s disease (AD. Methods: In a 6-month, observational, open-label study at 202 specialist sites in Greece, the effectiveness of memantine was evaluated using the Mini-Mental State Examination (MMSE and the Instrumental Activities of Daily Living (IADL scale at baseline, and after 3 and 6 months. Discontinuation rates and adverse drug reactions (ADRs were also recorded to evaluate the safety profile of memantine. Results: 2,570 patients participated in the study. Three and 6 months after baseline, MMSE and IADL scores were significantly improved compared to baseline. At the end of the study, 67% of the patients had improved their MMSE score; 7.1% of the patients reported ≧1 ADRs, and treatment was discontinued due to ADR in 0.7%. Conclusion: Memantine was well tolerated and had a positive effect on the patient’s cognitive and functional ability in real-life clinical practice, in agreement with randomized, controlled trials.

    Complementary medicine interventions are now successfully used to reduce stress as well as to stabilize hemodynamic indices within different procedures. The present study aimed to examine the effect of massage therapy and reflexotherapy on reducing stress in patients before coronary angiography. In this open-label clinical trial, 75 consecutive patients who were candidate for coronary angiography were randomly assigned to receive reflexotherapy (n = 25), or massage therapy (n = 25), or routine care (n = 25) before angiography. The Spielberger State-Trait Anxiety Inventory was used to determine the stress level of patients before and after interventions and vital signs were also measured. Improvement in diastolic blood pressure, heart rate, and respiratory rate was shown in the reflexotherapy group, and similar effects were observed following other interventions including massage therapy and routine resting program. In subjects who received reflexotherapy the level of stress decreased slightly compared with the other two groups. However, following interventions the level of stress in reflexotherapy group was shown to be lower than other study groups. Reflexotherapy before coronary angiography can help to stabilize vital sign as well as reduce the level of stress. The effect of massage therapy was limited to reducing stress.

    Hepatic cirrhosis is one of the leading causes of death worldwide, especially if complicated by ascites. This chronic condition can be related to the classical disease entity jalodara in Traditional Indian Medicine (Ayurveda). The present paper aims to evaluate the general potential of Ayurvedic therapy for overall clinical outcomes in hepatic cirrhosis complicated by ascites (HCcA). In form of a nonrandomized, uncontrolled, single group, open-label observational clinical study, 56 patients fulfilling standardized diagnostic criteria for HCcA were observed during their treatment at the P. D. Patel Ayurveda Hospital, Nadiad, India. Based on Ayurvedic tradition, a standardized treatment protocol was developed and implemented, consisting of oral administration of single and compound herbal preparations combined with purificatory measures as well as dietary and lifestyle regimens. The outcomes were assessed by measuring liver functions through specific clinical features and laboratory parameters and by evaluating the Child-Pugh prognostic grade score. After 6 weeks of treatment and a follow-up period of 18 weeks, the outcomes showed statistically significant and clinically relevant improvements. Further larger and randomized trials on effectiveness, safety, and quality of the Ayurvedic approach in the treatment of HCcA are warranted to support these preliminary findings.

    pro-drug of Ampicillin/Sulbactan, is a potent beta-lactamase inhibitor which can face this challenge. AIM: evaluate efficacy, safety and tolerability of Ampicillin/Sulbactan compared to Amoxicillin/Clavulanate in upper respiratory tract infections in adults. METHODS: 102 patients were enrolled and randomized to receive Ampicillin/Sulbactan or Amoxicillin/Clavulanate during 10 days. They were evaluated 10 and 30 days after treatment to learn about the therapeutic response. RESULTS: There were no differences between the two groups respecting cure at the end of treatment (visit 2 or at the end of the study (visit 3. Cure ratio was 61.7% and 93.2% (visits 2 and 3 in the Amoxicillin/Clavulanate group compared to 64.4% and 97.4%, respectively, in Ampicillin/Sulbactan group. The adverse events ratio for the two groups was the same (p=0.940. The number of patients with diarrhea was greater in the group of patients receiving Amoxicillin/Clavulanate (70.6% than in the group receiving Ampicillin/Sulbactan (29.4% (p=0.0164. CONCLUSIONS: Ampicillin/Sulbactan is as safe and efficient as Amoxicillin/Clavulanate in the empiric treatment of upper respiratory infections in adults. The low occurrence of diarrhea in the group receiving Ampicillin/Sulbactan needs confirmation in other studies.

    Objective In this clinical trial, we aimed to compare three means of performing chronic hemodialysis in patients with contra-indication to systemic heparinization. Methods This open-label monocentric randomized « n-of-one » trial, conducted in a single tertiary care center, recruited chronic hemodialysis patients with a contra-indication to systemic heparinization for at least 3 consecutive sessions. All patients underwent hemodialysis with an AN69ST dialyzer, and were administered three alternative dialysis procedures in a random sequence: intermittent saline flushes, constant saline infusion, or pre-dialysis heparin coating of the membrane. The primary outcome was the need to interrupt the dialysis session because of clotting events due to either (i) a complete coagulation of the circuit; (ii) a partial coagulation of the circuit; (iii) a>50% rise over baseline in the venous pressure. Results At the end of the inclusion period (May, 2007 to December, 2008), the number of patients to include (n = 75) was not reached: only 46 patients were included and underwent randomization. The study was terminated, and statistical analysis took into account 224 hemodialysis sessions performed in 44 patients with analyzable data. Heparin adsorption was associated with a significant reduction of the need to interrupt the dialysis session because of clotting events: odds ratio 0.3 (CI 95% 0.2 to 0.6; p3 h dialysis sessions and for having complete blood restitution. There were no significant effects of the dialysis procedure on weight loss, online ionic dialysance, and adverse events. Conclusion Heparin-coated AN69ST dialysis membrane is a safe and effective method to avoid or delay per-dialytic clotting events in patients with contra-indication to systemic anticoagulation. However, results are not generalizable safely to patients with active bleeding, since weak heparinemia, not assessed in this study, may occur. Trial Registration ClinicalTrials.gov NCT00473109. PMID

    Evidence is accumulating to support the presence of redox dysregulation in a number of psychiatric disorders, including bipolar disorder. This dysregulation may be amenable to therapeutic intervention. Glutathione is the predominant non-enzymatic intracellular free radical scavenger in the brain, and the most generic of all endogenous antioxidants in terms of action. N-acetylcysteine (NAC) is a glutathione precursor that effectively replenishes brain glutathione. Given the failure of almost all modern trials of antidepressants in bipolar disorder to demonstrate efficacy, and the limited efficacy of mood stabilisers in the depressive phase of the disorder, this is a major unmet need. This study reports data on the treatment of 149 individuals with moderate depression during the 2 month open label phase of a randomised placebo controlled clinical trial of the efficacy of 1g BID of NAC that examined the use of NAC as a maintenance treatment for bipolar disorder. In this trial, the estimated mean baseline Bipolar Depression Rating Scale (BDRS) score was 19.7 (SE=0.8), and the mean BDRS score at the end of the 8 week open label treatment phase was 11.1 (SE=0.8). This reduction was statistically significant (pdepression scores with NAC treatment. Large placebo controlled trials of acute bipolar depression are warranted. Copyright © 2011 Elsevier B.V.

At present there are few effective interventions for prefrontal cortex dysfunction in ASD. We report on an open-label, pilot study of intermittent TBS (iTBS to target executive function deficits and restricted, repetitive behaviors in male children and adolescents with ASD. Methods: Ten right-handed, male participants, aged 9-17 years with ASD were enrolled in an open-label trial of iTBS treatment. Fifteen sessions of neuronavigated iTBS at 100% motor threshold targeting the right dorsolateral prefrontal cortex were delivered over 3 weeks. Results: Parent report scores on the Repetitive Behavior Scale Revised and the Yale-Brown Obsessive Compulsive Scale demonstrated improvements with iTBS treatment. Participants demonstrated improvements in perseverative errors on the Wisconsin Card Sorting Test and total time for the Stroop test. The iTBS treatments were well tolerated with no serious adverse effects. Conclusion: These preliminary results suggest that further controlled interventional studies of iTBS for ASD are warranted.

    Methadone is an effective treatment for opioid dependence. When people who are receiving methadone maintenance treatment for opioid dependence are incarcerated in prison or jail, most US correctional facilities discontinue their methadone treatment, either gradually, or more often, abruptly. This discontinuation can cause uncomfortable symptoms of withdrawal and renders prisoners susceptible to relapse and overdose on release. We aimed to study the effect of forced withdrawal from methadone upon incarceration on individuals' risk behaviours and engagement with post-release treatment programmes. In this randomised, open-label trial, we randomly assigned (1:1) inmates of the Rhode Island Department of Corrections (RI, USA) who were enrolled in a methadone maintenance-treatment programme in the community at the time of arrest and wanted to remain on methadone treatment during incarceration and on release, to either continuation of their methadone treatment or to usual care--forced tapered withdrawal from methadone. Participants could be included in the study only if their incarceration would be more than 1 week but less than 6 months. We did the random assignments with a computer-generated random permutation, and urn randomisation procedures to stratify participants by sex and race. Participants in the continued-methadone group were maintained on their methadone dose at the time of their incarceration (with dose adjustments as clinically indicated). Patients in the forced-withdrawal group followed the institution's standard withdrawal protocol of receiving methadone for 1 week at the dose at the time of their incarceration, then a tapered withdrawal regimen (for those on a starting dose >100 mg, the dose was reduced by 5 mg per day to 100 mg, then reduced by 3 mg per day to 0 mg; for those on a starting dose >100 mg, the dose was reduced by 3 mg per day to 0 mg). The main outcomes were engagement with a methadone maintenance-treatment clinic after release from

    Full Text Available Abstract Background When planning a randomized controlled trial (RCT, investigators must select randomization and allocation procedures based upon a variety of factors. While third party randomization is cited as being among the most desirable randomization processes, many third party randomization procedures are neither feasible nor cost-effective for small RCTs, including pilot RCTs. In this study we present our experience with a third party randomization and allocation procedure that utilizes current technology to achieve randomization in a rapid, reliable, and cost-effective manner. Methods This method was developed by the investigators for use in a small 48-participant parallel group RCT with four study arms. As a nested study, the reliability of this randomization procedure was prospectively evaluated in this cohort. The primary outcome of this nested study was the proportion of subjects for whom allocation information was obtained by the Research Assistant within 15 min of the initial participant randomization request. A secondary outcome was the average time for communicating participant group assignment back to the Research Assistant. Descriptive information regarding any failed attempts at participant randomization as well as costs attributable to use of this method were also recorded. Statistical analyses included the calculation of simple proportions and descriptive statistics. Results Forty-eight participants were successfully randomized and group allocation instruction was received for 46 (96% within 15 min of the Research Assistant placing the initial randomization request. Time elapsed in minutes until receipt of participant allocation instruction was Mean (SD 3.1 +/− 3.6; Median (IQR 2 (2,3; Range (1–20 for the entire cohort of 48.

    Many women with major depressive disorder (MDD) respond inadequately to standard treatments. Augmentation of conventional antidepressants with creatine monohydrate and 5-hydroxytryptophan (5-HTP) could correct deficits in serotonin production and brain bioenergetics associated with depression in women, yielding synergistic benefit. We describe an open-label study of 5-HTP and creatine augmentation in women with MDD who had failed selective serotonin reuptake inhibitor (SSRI) or serotonin-norepinephrine reuptake inhibitor (SNRI) monotherapy. Fifteen women who were adequately adherent to an SSRI or SNRI and currently experiencing MDD, with a 17-item Hamilton Depression Rating Scale (HAM-D) score of 16 or higher, were treated with 5 g of creatine monohydrate daily and 100 mg of 5-HTP twice daily for 8 weeks, with 4 weeks of posttreatment follow-up. The primary outcome was change in mean HAM-D scores. Mean HAM-D scores declined from 18.9 (SD, 2.5) at pretreatment visits to 7.5 (SD, 4.4) (P creatine and 5-HTP may represent an effective augmentation strategy for women with SSRI- or SNRI-resistant depression. Given the limitations of this small, open-label trial, future study in randomized, placebo-controlled trials is warranted.

    We aimed to evaluate the anti-albuminuric effects of topiroxostat in Japanese hyperuricemic patients with diabetic nephropathy. In this 24-week, multicenter, open-label, randomized (1:1) trial, we assigned hyperuricemic patients with diabetic nephropathy (estimated glomerular filtration rate ≥ 20 mL/min/1.73m 2 ) and overt proteinuria (0.3 ≤ urine protein to creatinine ratio (UPCR) <3.5 g/g Cr) to either high dose (160 mg daily) or low dose (40 mg daily) topiroxostat. The primary endpoint was the change in albuminuria indicated by urine albumin-to-creatinine ratio (UACR) from the baseline at the final time point. A total of 80 patients underwent randomization. The changes in UACR after 24 weeks of treatment (or at the final time point if patients failed to reach 24 weeks) relative to the baseline were -122 mg/gCr (95% CI: -5.1 to -240.1, P = 0.041) in patients treated with high dose, while treatment with low dose topiroxostat could not show significant reduction (P = 0.067). In the linear mixed model including baseline albuminuria, eGFR, age, and sex as covariates, the decreases in UACR were still significant from baseline to 12 weeks by 228.7 ± 83.2 mg/gCr (P = 0.0075) in the high dose group. The adverse-event profile during this study was not different between the groups. Topiroxostat 160 mg daily reduced albuminuria in patients with diabetic nephropathy.

    Purpose Several open-label randomized studies have suggested that in vivo T-cell depletion with anti-T-lymphocyte globulin (ATLG; formerly antithymocyte globulin-Fresenius) reduces chronic graft-versus-host disease (cGVHD) without compromising survival. We report a prospective, double-blind phase III trial to investigate the effect of ATLG (Neovii Biotech, Lexington, MA) on cGVHD-free survival. Patients and Methods Two hundred fifty-four patients 18 to 65 years of age with acute leukemia or myelodysplastic syndrome who underwent myeloablative HLA-matched unrelated hematopoietic cell transplantation (HCT) were randomly assigned one to one to placebo (n =128 placebo) or ATLG (n = 126) treatment at 27 sites. Patients received either ATLG or placebo 20 mg/kg per day on days -3, -2, -1 in addition to tacrolimus and methotrexate as GVHD prophylaxis. The primary study end point was moderate-severe cGVHD-free survival. Results Despite a reduction in grade 2 to 4 acute GVHD (23% v 40%; P = .004) and moderate-severe cGVHD (12% v 33%; P < .001) in ATLG recipients, no difference in moderate-severe cGVHD-free survival between ATLG and placebo was found (2-year estimate: 48% v 44%, respectively; P = .47). Both progression-free survival (PFS) and overall survival (OS) were lower with ATLG (2-year estimate: 47% v 65% [ P = .04] and 59% v 74% [ P = .034], respectively). Multivariable analysis confirmed that ATLG was associated with inferior PFS (hazard ratio, 1.55; 95% CI, 1.05 to 2.28; P = .026) and OS (hazard ratio, 1.74; 95% CI, 1.12 to 2.71; P = .01). Conclusion In this prospective, randomized, double-blind trial of ATLG in unrelated myeloablative HCT, the incorporation of ATLG did not improve moderate-severe cGVHD-free survival. Moderate-severe cGVHD was significantly lower with ATLG, but PFS and OS also were lower. Additional analyses are needed to understand the appropriate role for ATLG in HCT.

    Our previous studies have demonstrated the tolerability and low side-effect profile of office-based sclerotherapy with sodium tetradecyl sulfate (STS) for treating recurrent epistaxis due to hereditary hemorrhagic telangiectasia (HHT). The objective of this study was to use a prospective randomized trial to determine the effectiveness of sclerotherapy with STS vs standard treatment. This prospective randomized trial (conducted from November 1, 2011, through January 31, 2014) involved 17 patients with recurrent epistaxis due to HHT. We defined standard treatment as continuation of any treatment that the patient had previously undergone, such as moisturization, packing, and cautery. We used a crossover design, so study participants were randomized to either sclerotherapy or standard treatment during the first time period, and then to the other during the second period. The primary outcome measure was frequency and severity of epistaxis, as measured by the epistaxis severity score (ESS). The ESS is a 10-point scale, with higher scores corresponding to more bleeding. After controlling for treatment order, bleeding was substantially better controlled after sclerotherapy; the ESS after sclerotherapy was nearly one point lower than after standard treatment (-0.95, 1-sided p = 0.027). Treatment order, baseline ESS, the number of lesions, moisturization practices, and a history of previous blood transfusions did not significantly affect the results. This trial demonstrated that sclerotherapy with STS (vs standard treatment) significantly reduced epistaxis due to HHT. © 2015 ARS-AAOA, LLC.

    The e-learning education is a promising method, but there are few prospective randomized publications in oncology. The purpose of this study was to assess the level of retention of information in oncology from undergraduate students of physiotherapy. A prospective, controlled, randomized, crossover study, 72 undergraduate students of physiotherapy, from the second to fourth years, were randomized to perform a course of physiotherapy in oncology (PHO) using traditional classroom or e-learning. Students were offered the same content of the subject. The teacher in the traditional classroom model and the e-learning students used the Articulate® software. The course tackled the main issues related to PHO, and it was divided into six modules, 18 lessons, evaluated by 126 questions. A diagnosis evaluation was performed previous to the course and after every module. The sample consisted of 67 students, allocated in groups A (n = 35) and B (n = 32), and the distribution was homogeneous between the groups. Evaluating the correct answers, we observed a limited score in the pre-test (average grade 44.6 %), which has significant (p e-learning, a fact that encourages the use of e-learning in oncology.
