To date, there is a lack of long-term safety and efficacy data for iron chelation therapy in transfusion-dependent patients with sickle cell disease (SCD). To evaluate the long-term safety and efficacy of deferasirox (a once-daily oral iron chelator), patients with SCD completing a 1-year, Phase II, randomized, deferoxamine (DFO)-controlled study entered a 4-year extension, continuing to receive deferasirox, or switching from DFO to deferasirox. Average actual deferasirox dose was 19·4 ± 6·3 mg/kg per d. Of 185 patients who received at least one deferasirox dose, 33·5% completed the 5-year study. The most common reasons for discontinuation were withdrawal of consent (23·8%), lost to follow-up (9·2%) and adverse events (AEs) (7·6%). Investigator-assessed drug-related AEs were predominantly gastrointestinal [including nausea (14·6%), diarrhoea (10·8%)], mild-to-moderate and transient in nature. Creatinine clearance remained within the normal range throughout the study. Despite conservative initial dosing, serum ferritin levels in patients with ≥4 years deferasirox exposure significantly decreased by −591 μg/l (95% confidence intervals, −1411, −280 μg/l; P=0·027; n=67). Long-term deferasirox treatment for up to 5 years had a clinically acceptable safety profile, including maintenance of normal renal function, in patients with SCD. Iron burden was substantially reduced with appropriate dosing in patients treated for at least 4 years. PMID:21592110

Long-term safety, efficacy, and tolerability of imidafenacin in the treatment of overactive bladder: a review of the Japanese literature

PubMed Central

Masumori, Naoya

Imidafenacin is an antimuscarinic agent with high affinity for the M3 and M1 muscarinic receptor subtypes and low affinity for the M2 subtype, and is used to treat overactive bladder. Several animal studies have demonstrated that imidafenacin has organ selectivity for the bladder over the salivary glands, colon, heart, and brain. In Phase I studies in humans, the approximately 2.9-hour elimination half-life of imidafenacin was shorter than that of other antimuscarinics such as tolterodine and solifenacin. Imidafenacin was approved for clinical use in overactive bladder in Japan in 2007 after a randomized, double-blind, placebo-controlled Phase II study and a propiverine-controlled Phase III study conducted in Japanese patients demonstrated that imidafenacin 0.1 mg twice daily was clinically effective for treating overactive bladder and was not inferior to propiverine for reduction of episodes of incontinence, with a better safety profile than propiverine. Several short-term clinical studies have demonstrated that imidafenacin also improves sleep disorders, nocturia, and nocturia-related quality of life. In addition, it is speculated that addon therapy with imidafenacin is beneficial for men with benign prostatic hyperplasia whose overactive bladder symptoms are not controlled by alpha-1 adrenoceptor antagonists. No cognitive impairment or influence of imidafenacin on the QTc interval has been observed. Although there have been very few relevant long-term clinical studies, the available information suggests the long-term efficacy, safety, and tolerability of imidafenacin, with less frequent severe adverse events, such as dry mouth and constipation. In addition, imidafenacin can be used safely for a long time even for cognitively vulnerable elderly patients with symptoms of overactive bladder. Thus, it is highly likely that imidafenacin is safe, efficacious, and tolerable to control symptoms of overactive bladder even over the long term. However, it remains unknown

In the primary analysis of the ERIVANCE BCC trial, vismodegib, the first US Food and Drug Administration-approved Hedgehog pathway inhibitor, showed objective response rates (ORRs) by independent review facility (IRF) of 30% and 43% in metastatic basal cell carcinoma (mBCC) and locally advanced BCC (laBCC), respectively. ORRs by investigator review were 45% (mBCC) and 60% (laBCC). Herein, we present long-term safety and final investigator-assessed efficacy results in patients with mBCC or laBCC. One hundred four patients with measurable advanced BCC received oral vismodegib 150 mg once daily until disease progression or intolerable toxicity. The primary end point was IRF-assessed ORR. Secondary end points included ORR, duration of response (DOR), progression-free survival, overall survival (OS), and safety. At data cutoff (39 months after completion of accrual), 8 patients were receiving the study drug (69 patients in survival follow-up). Investigator-assessed ORR was 48.5% in the mBCC group (all partial responses) and 60.3% in the laBCC group (20 patients had complete response and 18 patients had partial response). ORRs were comparable across patient subgroups, including aggressive histologic subtypes (eg, infiltrative BCC). Median DOR was 14.8 months (mBCC) and 26.2 months (laBCC). Median OS was 33.4 months in the mBCC cohort and not estimable in the laBCC cohort. Adverse events remained consistent with clinical experience. Thirty-three deaths (31.7%) were reported; none were related to vismodegib. This long-term update of the ERIVANCE BCC trial demonstrated durability of response, efficacy across patient subgroups, and manageable long-term safety of vismodegib in patients with advanced BCC. This study was registered prospectively with Clinicaltrials.gov , number NCT00833417 on January 30, 2009.

This study was designed to follow the long-term efficacy, safety, and tolerability of rasagiline for Parkinson's disease (PD) with data collected from all patients who had ever taken rasagiline during the 12-month TEMPO monotherapy trial (N = 398) and subsequent open-label extension. Patients were followed for up to 6.5 years with a mean of 3.5 +/- 2.1 years. After 12 months, additional PD medications were added as required. Of patients remaining in the trial at 2 years, 46% were maintained on rasagiline monotherapy. The majority of patients received a dopamine agonist prior to levodopa as the first additional dopaminergic agent. Analysis using a Kaplan-Meier method indicated that by 5.4 years only 25% of patients progressed to Hoehn & Yahr stage III. Rasagiline was well tolerated, with 11.3% of patients (45/398) withdrawing because of an adverse event. Rasagiline therapy for PD was effective, well tolerated, and safe in this long-term trial.

Abstract Objectives. To evaluate the long-term efficacy and safety of certolizumab pegol (CZP) plus methotrexate treatment and to assess the efficacy of two CZP maintenance dosing schedules in Japanese rheumatoid arthritis (RA) patients with an inadequate response to methotrexate. Methods. J-RAPID double-blind patients were entered into an open-label extension (OLE) study. Patients withdrawn due to lack of efficacy at 16 weeks and double-blind completers without a week-24 American College of Rheumatology (ACR) 20 response received CZP 200 mg every other week (Q2W) plus methotrexate. Double-blind completers with week-24 ACR20 responses were randomized to CZP 200 mg Q2W plus methotrexate or CZP 400 mg every 4 weeks plus methotrexate. Results. The ACR20/ACR50/ACR70 response rates of double-blind completers (n = 204) were 89.7%/67.2%/36.3% at OLE entry and 95.6%/84.8%/58.3% at 52 weeks, respectively. Other clinical, functional and radiographic outcomes were sustained with long-term CZP plus methotrexate. Long-term treatment with CZP was well-tolerated with no new unexpected adverse events observed. The efficacy and safety of CZP treatment were similar between the two dosing schedules. Conclusions. Continued CZP administration with methotrexate maintained efficacy over 52 weeks and was well-tolerated for Japanese RA patients. No obvious differences in clinical efficacy and safety were observed between the two dosing schedules, giving flexibility in maintenance administration schedules. PMID:24593170

To evaluate the long-term safety and efficacy of fulranumab in patients with knee or hip pain caused by moderate-to-severe chronic osteoarthritis (OA). In this phase II double-blind, placebo-controlled extension study, patients who were randomized in equal proportions to receive subcutaneous doses of either placebo or fulranumab (1 mg every 4 weeks, 3 mg every 8 weeks, 3 mg every 4 weeks, 6 mg every 8 weeks, or 10 mg every 8 weeks) in the 12-week double-blind efficacy phase and who completed this double-blind efficacy phase were eligible to continue the dosage throughout a 92-week double-blind extension phase, followed by a 24-week posttreatment follow-up period. Safety assessments included evaluation of treatment-emergent adverse events (TEAEs), pre-identified AEs of interest, and joint replacements. Efficacy assessments included changes from baseline to the end of the double-blind extension phase in scores on the patient's global assessment and the pain and physical function subscales of the Western Ontario and McMaster Universities Osteoarthritis Index. Overall, 401 of the 423 patients who completed the 12-week double-blind efficacy phase entered the extension study. Long-term sustained improvements were observed in all efficacy parameters following fulranumab treatment (1 mg every 4 weeks, 3 mg every 4 weeks, and 10 mg every 8 weeks) as compared with placebo. Similar percentages of patients in both groups experienced TEAEs (88% taking placebo and 91% taking fulranumab; all phases). Across all fulranumab groups, arthralgia (21%) and OA (18%) (e.g., exacerbation of OA pain) were the most common TEAEs. The most common serious TEAEs were the requirement for knee (10%) and hip (7%) arthroplasty, with 80% occurring during the posttreatment follow-up period. Neurologic-related TEAEs (28%; all phases) were generally mild-to-moderate. Overall, 81 joint replacements were performed in 71 patients (8 [11%] receiving placebo and 63 [89%] receiving fulranumab); 15 patients

In Phase 3 studies of ustekinumab, a fully human monoclonal IL-12/23p40 antibody approved for moderate-to-severe Crohn's disease, patients entered a long-term extension after completing 8 weeks of induction and 44 weeks of maintenance treatment. Efficacy through 92 weeks and safety through 96 weeks of IM-UNITI maintenance are reported. UNITI-1 (TNF-antagonist failures) and UNITI-2 (conventional therapy failures) patients (N = 1281) entered IM-UNITI, including 397 ustekinumab intravenous induction responders randomised to subcutaneous ustekinumab 90 mg every 12 weeks, every 8 weeks, or placebo and 884 nonrandomised patients. Dose-adjustment to 90 mg every 8 weeks occurred in patients randomised to 90 mg every 12 weeks and placebo patients with loss of response (Weeks 8-32). All Week 44 completers could enter the long-term extension without further dose adjustment. Placebo patients discontinued following study unblinding. A total of 718 patients (all treated) entered the long-term extension (298 randomised and 420 not randomised). Overall, 86.5% (621/718) completed Week 96. The proportions of randomised patients in clinical remission were generally maintained from Week 44 through 92 in ustekinumab 90 mg every 12 weeks (77.4% to 72.6%), every 8 weeks (84.1% to 74.4%), and prior dose adjustment groups (63.4% to 53.5%). At Week 92, the proportions of patients in clinical remission were similar in the ustekinumab 90 mg every 12 weeks and every 8 weeks groups and lower in patients with prior dose adjustment. Proportions of patients in clinical remission at Week 92 for all treated every 8 weeks (64.4%) and every 12 weeks (64.3%) groups were lower than randomised every 8 weeks (74.4%) and every 12 weeks (72.6%) groups, but similarly maintained. Safety events (per hundred patient-years) were similar among all placebo and ustekinumab patients (Week 0-96), including adverse events (484.39 vs 447.76), serious adverse events (19.24 vs 18.82), and serious

Objective: To determine the safety and efficacy of long-term use of mizoribine by undertaking a 3-year post-marketing surveillance study. Methods: Subjects were all lupus nephritis patients newly treated with mizoribine between 1 October 2003 and 30 September 2005 at contracted study sites. Results: Mizoribine was administered to 881 lupus nephritis patients in the safety analysis set consisting of 946 patients recruited from 281 contracted study sites after satisfying the eligibility criteria. There were 301 events of adverse drug reactions that were observed in 196 (20.7%) of the 946 subjects. There were 34 events of serious adverse drug reactions in 31 patients (3.2%). No deterioration in hematological and biochemical test values was observed, but immunological testing showed significant improvements in C3, CH50, and anti-DNA antibody titers. The negative rate of proteinuria also increased over time. The median steroid dosage was 15 mg/day at the commencement of treatment, but was reduced to 10 mg/day at 12 months and 8 mg/day at 36 months. Conclusion: The findings of the 3-year long-term drug use surveillance study indicated that mizoribine can be used over the long term with relatively few adverse drug reactions, suggesting its suitability for use in maintenance drug therapy.

The GEMINI long-term safety [LTS] study is a continuing phase 3 trial investigating the safety and efficacy of vedolizumab, an α4β7 integrin antagonist for ulcerative colitis [UC] and Crohn's disease. We provide an interim analysis of efficacy in patients with UC. Patients from the C13004 and GEMINI 1 studies and a cohort of vedolizumab-naïve patients received open-label vedolizumab every 4 weeks. Interim data were collected from May 22, 2009 to June 27, 2013. Clinical response and remission, evaluated using partial Mayo scores, and health-related quality of life [HRQL] were assessed for up to 152 weeks of cumulative treatment in the efficacy population. As of June 27, 2013, 63% of the efficacy population [n = 532/845] were continuing treatment. Among patients who responded to vedolizumab induction and had data available, 88% [n = 120/136] were in remission after 104 weeks of exposure (96% [n = 70/73] after 152 weeks). Among patients who withdrew from every-8-week vedolizumab maintenance in GEMINI 1 [n = 32] before week 52, increased dosing to every 4 weeks in GEMINI LTS resulted in response and remission rates of 41% and 28%, respectively, after 52 weeks, an increase from 19% and 6%, respectively, from before the dose increase. Similar benefits were demonstrated regardless of prior tumour necrosis factor-antagonist exposure. Durable benefits on HRQL were also observed. Patients with UC experienced clinical and HRQL improvements with continued vedolizumab treatment. Increased dosing frequency to every 4 weeks was beneficial in patients who had loss of response to 8-weekly dosing. Copyright © 2016 European Crohn’s and Colitis Organisation (ECCO).

The study evaluated the long-term efficacy and safety profiles of self-intracavernous injection of prostaglandin E1 (PGE1) for erectile dysfunction (ED). Four hundred and sixteen ED patients were treated with self-intracavernous injection of PGE1 from January 1998 to December 2007 in our outpatient service. Follow-up was made to investigate the efficacy and side effects of this treatment. It was found that 261 patients (62.7%) felt satisfied and kept using this treatment due to its advantages of satisfactory efficacy and reasonable expense. Twenty-seven of them (6.5%) got rid of PGE1 treatment after five times injections and did not need any other drugs to maintain satisfactory sexual lives. Two hundred and fourteen (51.4%) patients kept using this treatment for over 1 year, 26 (6.2%) over 5 years, 12 (2.9%) over 8 years and 7 (1.7%) over 10 years. The major complications of self-intracavernous injection of PGE1 include fibrosis of corpus cavernosum (three cases), ecchymosis associated with vascular injury due to injection (23 cases) and pain associated with injection (295 cases). There were no patients displaying priapism. It is concluded that self-intracavernous injection of PGE1 is a safe and effective treatment for ED with various aetiologies and a broad range of severity, and no serious complications were observed after long-term application. © 2011 Blackwell Verlag GmbH.

Current ocular GvHD (oGvHD) treatments are suboptimal. We investigated the safety and efficacy of long-term continuous treatment with autologous platelet lysate (PL) drops in patients with oGvHD Dry Eye Syndrome (DES) score 2-3 refractory to topical conventional therapy. Ophthalmic evaluation was performed at 6 month intervals. Symptoms were assessed using the Glaucoma Symptom Scale (GSS). Patients were defined 'responders' when showing a reduction at least one grade on National Institutes of Health Eye Score from baseline at the 6 month visit. Thirty-one patients were included, and 16 (51%) completed 36 months of follow-up (range 6.5-72.7). At 6 months all patients were classified as responders: median GSS symptom score decreased from 70 to 41 (33 at 36 months), median GSS function score reduced from 68 to 46 (33 at 36 months) (all P<0.001). Median Tear Break Up Time improved from 3 to 6 s after 6 months and was maintained over time. All signs improved at 6 and 36 months (clinical and statistical significance). No severe adverse events occurred. Long-term treatment with PL drops is secure and effective for oGvHD and can be an efficient therapy option from initial stages of oGvHD to prevent permanent ocular impairment and improving quality of life.

Long-term aspirin use in cardiovascular disease prevention may result in gastrointestinal bleeding. Although proton pump inhibitors (PPI) have been shown to reduce the risks of peptic ulcers and dyspeptic symptoms in long-term aspirin users in the randomized controlled trials, there are safety concerns about the long-term use of PPI. What is the safety and efficacy of PPI in patients using aspirin in long term for prevention of cardiovascular diseases and stroke? We searched MEDLINE, EMBASE, CENTRAL, CINAHL, ProQuest, and relevant references from inception through February 2015, and used random-effects model for meta-analysis. A total of 10 publications from 9 studies (n = 6382) were included in the meta-analysis. Compared with control, PPI reduced the risks of peptic ulcers [risk ratio (RR): 0.19; 95% confidence interval: 0.13-0.26; P < 0.00001], gastric ulcers [0.24 (0.16-0.35); P < 0.00001], duodenal ulcers [0.12 (0.05-0.29); P < 0.00001], bleeding ulcers [0.22 (0.10-0.51); P = 0.0004], and erosive esophagitis [0.14 (0.07-0.28); P < 0.00001]. PPI increased the resolution of epigastric pain [1.13 (1.03-1.25); P = 0.01], heartburn [1.24 (1.18-1.31); P < 0.00001], and regurgitation [1.26 (1.13-1.40); P < 0.0001], but did not increase the risks of all-cause mortality [1.72 (0.61-4.87); P = 0.31], cardiovascular mortality [1.80 (0.59-5.44); P = 0.30], nonfatal myocardial infarction/ischemia [0.56 (0.22-1.41); P = 0.22], ischemic stroke/transient ischemic attack [1.09 (0.34-3.53); P = 0.89] and other adverse events. The PPI seems to be effective in preventing peptic ulcers and erosive esophagitis and in resolution of dyspeptic symptoms without increasing adverse events, cardiac risks or mortality in long-term aspirin users.

The efficacy and safety of abatacept in patients with juvenile idiopathic arthritis (JIA) who experienced an inadequate response to disease-modifying antirheumatic drugs were previously established in a phase III study that included a 4-month open-label lead-in period, a 6-month double-blind withdrawal period, and a long-term extension (LTE) phase. The aim of this study was to present the safety, efficacy, and patient-reported outcomes of abatacept treatment (10 mg/kg every 4 weeks) during the LTE phase, for up to 7 years of followup. Patients enrolled in the phase III trial could enter the open-label LTE phase if they had not achieved a response to treatment at month 4 or if they had received abatacept or placebo during the double-blind period. One hundred fifty-three (80.5%) of 190 patients entered the LTE phase, and 69 patients (36.3%) completed it. The overall incidence rate (events per 100 patient-years) of adverse events decreased during the LTE phase (433.61 events during the short-term phase [combined lead-in and double-blind periods] versus 132.39 events during the LTE phase). Similar results were observed for serious adverse events (6.82 versus 5.60), serious infections (1.13 versus 1.72), malignancies (1.12 versus 0), and autoimmune events (2.26 versus 1.18). American College of Rheumatology (ACR) Pediatric 30 (Pedi 30) responses, Pedi 70 responses, and clinically inactive disease status were maintained throughout the LTE phase in patients who continued to receive therapy. Improvements in the Child Health Questionnaire physical and psychosocial summary scores were maintained over time. Long-term abatacept treatment for up to 7 years was associated with consistent safety, sustained efficacy, and quality-of-life benefits in patients with JIA. © 2015 The Authors.

It has been previously shown that biosimilar infliximab CT-P13 is effective and safe in inducing remission in inflammatory bowel diseases. We report here the 1-year outcomes from a prospective nationwide inflammatory bowel disease cohort. A prospective, nationwide, multicenter, observational cohort was designed to examine the efficacy and safety of CT-P13 in the induction and maintenance treatment of Crohn's disease (CD) and ulcerative colitis (UC). Demographic data were collected and a harmonized monitoring strategy was applied. Clinical remission, response, and biochemical response were evaluated at weeks 14, 30, and 54, respectively. Safety data were registered. Three hundred fifty-three consecutive inflammatory bowel disease (209 CD and 144 UC) patients were included, of which 229 patients reached the week 54 endpoint at final evaluation. Age at disease onset: 24/28 years (median, interquartile range: 19-34/22-39) in patients with CD/UC. Forty-nine, 53, 48% and 86, 81 and 65% of patients with CD reached clinical remission and response by weeks 14, 30, and 54, respectively. Clinical remission and response rates were 56, 41, 43% and 74, 66, 50% in patients with UC. Clinical efficacy was influenced by previous anti-tumor necrosis factor (TNF) exposure in patients with a drug holiday beyond 1 year. The mean C-reactive protein level decreased significantly in both CD and UC by week 14 and was maintained throughout the 1-year follow-up (both UC/CD: P < 0.001). Thirty-one (8.8%) patients had infusion reactions and 32 (9%) patients had infections. Antidrug antibody positivity rates were significantly higher throughout patients with previous anti-TNF exposure; concomitant azathioprine prevented antidrug antibody formation in anti-TNF-naive patients with CD. Results from this prospective nationwide cohort confirm that CT-P13 is effective and safe in inducing and maintaining long-term remission in both CD and UC. Efficacy was influenced by previous anti-TNF exposure; no

A candidate tetravalent dengue vaccine is being assessed in three clinical trials involving more than 35,000 children between the ages of 2 and 16 years in Asian-Pacific and Latin American countries. We report the results of long-term follow-up interim analyses and integrated efficacy analyses. We are assessing the incidence of hospitalization for virologically confirmed dengue as a surrogate safety end point during follow-up in years 3 to 6 of two phase 3 trials, CYD14 and CYD15, and a phase 2b trial, CYD23/57. We estimated vaccine efficacy using pooled data from the first 25 months of CYD14 and CYD15. Follow-up data were available for 10,165 of 10,275 participants (99%) in CYD14 and 19,898 of 20,869 participants (95%) in CYD15. Data were available for 3203 of the 4002 participants (80%) in the CYD23 trial included in CYD57. During year 3 in the CYD14, CYD15, and CYD57 trials combined, hospitalization for virologically confirmed dengue occurred in 65 of 22,177 participants in the vaccine group and 39 of 11,089 participants in the control group. Pooled relative risks of hospitalization for dengue were 0.84 (95% confidence interval [CI], 0.56 to 1.24) among all participants, 1.58 (95% CI, 0.83 to 3.02) among those under the age of 9 years, and 0.50 (95% CI, 0.29 to 0.86) among those 9 years of age or older. During year 3, hospitalization for severe dengue, as defined by the independent data monitoring committee criteria, occurred in 18 of 22,177 participants in the vaccine group and 6 of 11,089 participants in the control group. Pooled rates of efficacy for symptomatic dengue during the first 25 months were 60.3% (95% CI, 55.7 to 64.5) for all participants, 65.6% (95% CI, 60.7 to 69.9) for those 9 years of age or older, and 44.6% (95% CI, 31.6 to 55.0) for those younger than 9 years of age. Although the unexplained higher incidence of hospitalization for dengue in year 3 among children younger than 9 years of age needs to be carefully monitored during long-term

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.

To investigate the efficacy and safety of long-term lamotrigine (LTG) monotherapy in Japanese and South Korean pediatric patients with newly diagnosed typical absence seizures. Six Japanese patients and one South Korean patient were enrolled in the extension phase of the study after completing the 12-week maintenance phase of an open-label clinical study of LTG monotherapy. During the extension phase, patients underwent efficacy and safety evaluation every 12 weeks. Of the seven patients, six patients completed the extension phase. The seizure-free rate confirmed by hyperventilation (HV)-electroencephalography ranged from 71.4% to 100.0% at each visit up to Week 168 of the extension phase. Similar effects were confirmed by HV-clinical signs and seizure diaries. Although no unexpected adverse events were observed, one Japanese patient was withdrawn from the extension phase due to mild drug-related rash developed 842 days after the start of LTG. Although the number of patients is limited, long-term LTG monotherapy appeared to be effective and generally well tolerated in Japanese and South Korean pediatric patients with typical absence seizures.

Risperidone long-acting injection: a review of its long term safety and efficacy

PubMed Central

Rainer, Michael K

2008-01-01

A long-acting form of the second-generation antipsychotic drug risperidone is now broadly available for the treatment of schizophrenia and closely related psychiatric conditions. It combines the advantage of previously available depot formulations for first-generation drugs with the favorable characteristics of the modern “atypical” antipsychotics, namely higher efficacy in the treatment of the negative symptoms of schizophrenia and reduced motor disturbances. Published clinical studies show an objective clinical efficacy (as per psychiatric symptom scores and relapse data) that exceeds that of oral atypical antipsychotics when patients are switched to the long-acting injectable form, a low incidence of treatment-emergent extrapyramidal side effects, and very good acceptance by patients. Available data for maintenance treatment of bipolar disorder show equivalence with the oral form instead of superiority, but are still limited. As it seems likely that efficacy benefits are mostly due to the fact that the injectable form reduces the demand for patient compliance to one physician visit every 2 weeks instead of self-administration on a daily or twice-daily basis, additional potential could exist in other psychiatric disorders where atypical antipsychotic drugs are of benefit but where patient adherence to treatment schedules is typically low.

Societies worldwide are faced with a progressive increase in immune-mediated health problems such as allergic, autoimmune, and inflammatory diseases, as well as obesity. Perinatal administration of specific probiotic bacteria is an attractive approach in reducing the risk of these conditions, but long-term efficacy and safety data are lacking. The aim here was to evaluate the clinical benefit and long-term safety of specific probiotics administered during the perinatal period. The probiotic strains used were Lactobacillus rhamnosus GG, Bifidobacterium lactis Bb-12, Lactobacillus paracasei ST11, and Bifidobacterium longum BL999. The children involved have subsequently undergone prospective long-term follow-up. In addition to physical examination, data were collected by structured questionnaires on non-communicable diseases and continued probiotic use, and growth data from welfare clinics and school nurses. Altogether 303 mother-infant pairs were included in the analysis. Seventy-six of 163 (47%) children receiving perinatal probiotics had developed allergic disease compared with 79 of 140 (56%) receiving placebo (OR 0.67, 95% confidence intervals [CI] 0.43-1.06, p = 0.09). Fifty-nine of 133 (44%) children receiving L. rhamnosus GG perinatally had developed allergic disease, OR 0.62, 95% CI 0.38-0.99, p = 0.047, as compared to placebo. We found no differences in growth or non-communicable disease prevalence between children receiving perinatally probiotics or placebo. Perinatal probiotic administration is safe in long-term follow-up. Children receiving L. rhamnosus GG perinatally tended to have decreased allergy prevalence. © 2016 John Wiley & Sons A/S.

Data regarding the efficacy and safety of sodium-glucose cotransporter 2 inhibitors in the real-world setting in Japan are limited. The STELLA-LONG TERM study is an ongoing 3-year post-marketing surveillance study of ipragliflozin in type 2 diabetes (T2D) patients. Here, we report the interim results (including 3-, 12-, and 24-month data). All Japanese patients with T2D who were first prescribed ipragliflozin between 17 July 2014 and 16 October 2015 at participating centers in Japan were registered in STELLA-LONG TERM. At 3, 12, and 24 months, the safety analysis set comprised 11,053, 5475, and 138 patients, respectively; the efficacy analysis set comprised 8757 patients. Ipragliflozin treatment resulted in statistically significant improvements versus baseline in hemoglobin A1c, fasting plasma glucose concentration, body weight, blood pressure, heart rate, and serum concentrations of low-density lipoprotein cholesterol and triglycerides. The adverse drug reaction incidence rate was 10.71%, the most common reactions being renal and urinary disorders (5.06%), infections and infestations (1.24%), and skin and subcutaneous tissue disorders (1.14%). Ipragliflozin was well tolerated and effective in Japanese patients with T2D; no new safety issues were identified.

Prospective evaluation of the long-term efficacy and safety of the 5% lidocaine medicated plaster in patients with post-herpetic neuralgia (PHN). Patients with persisting pain for ≥3 months after acute herpes zoster and a baseline pain intensity of at least 4 on an 11-point numerical rating scale (NRS 0-10) were treated with 5% lidocaine medicated plasters for up to 5 years and monitored in regular intervals. Efficacy parameters are presented for the first 4 years and include patients' recall of pain relief (6-point verbal rating scale (VRS), clinical global impression of change (CGIC), patients' global impression of change PGIC), and the global evaluations of study medication. Safety parameters (clinical examination, skin evaluation, laboratory) and adverse events (AEs) were assessed at regular visits. KF10004/02. A total of 102 patients continuing from a 1 year main study period were included in an extension phase of up to 3 years. Ten patients (9.8%) dropped out due to lack of efficacy and 9 patients (8.8%) due to treatment-related AEs; 56 patients (54.9%) left the study for non-treatment-related reasons. Twenty-seven patients (26.4%) were still under treatment after a total treatment period of 4 years. On average, a pain relief of at least 4.3 (between moderate and a lot) was achieved throughout the study. At all visits the CGIC and the PGIC were much or very much improved in about 80% of patients. At the final visit, study medication was rated at least to be good by 91% of physicians and 89% of patients. Drug-related adverse events (DRAEs) were reported in 19 of 102 patients, mainly mild to moderate localized skin reactions. There were no hints for a reduced analgesic effect or an increase of DRAEs with long-term treatment. This study demonstrates that long-term treatment of ≥12 months with the 5% lidocaine medicated plaster is effective and well tolerated in PHN patients. These findings support the recommendations to use the 5% lidocaine medicated plaster

Sacubitril/valsartan (LCZ696), a first-in-class angiotensin receptor-neprilysin inhibitor, demonstrated significant reductions in office and 24 h ambulatory blood pressure (BP) over 8 weeks in Asian patients with hypertension. This 52-week extension to the 8-week core study was aimed at evaluating the long-term safety, tolerability and efficacy of sacubitril/valsartan. Patients who completed an 8-week randomized study (the core study) were enrolled in this 52-week open-label study and received sacubitril/valsartan 200 mg QD. The sacubitril/valsartan dose was uptitrated to 400 mg QD if BP was uncontrolled (>140/90 mm Hg) after 4 weeks. Subsequently, in patients with uncontrolled BP, treatment was intensified every 4 weeks with amlodipine 5-10 mg followed by hydrochlorothiazide 6.25-25 mg. Of the 341 patients enrolled, 7 (2.1%) discontinued the study drug due to adverse events (AEs). The incidence of AEs and serious AEs were 63.9 and 3.8%, respectively, and no deaths were reported in this study. The most frequent AEs were nasopharyngitis (18.2%) and dizziness (8.8%). Events that were potentially indicative of low BP were infrequent. One patient reported mild transient angioedema (lasting 2.5 h) that resolved without treatment but led to study drug discontinuation. The sacubitril/valsartan-based regimen provided clinically significant mean sitting systolic BP (msSBP) and mean sitting diastolic BP (msDBP) reductions from baseline (-24.7/-16.2 mm Hg). The overall BP control, msSBP and msDBP response rates were 75.3, 90.6 and 87.6%, respectively. Long-term use of sacubitril/valsartan was generally safe and well-tolerated in patients with hypertension and provided significant BP reductions from baseline.

Long-term outcome data provide important insights into the clinical utility of enzyme replacement therapies. Such data are presented for velmanase alfa in the treatment of alpha-mannosidosis (AM). Patient data (n = 33; 14 adults, 19 paediatric) from the clinical development programme for velmanase alfa were integrated in this prospectively-designed analysis of long-term efficacy and safety. Patients who participated in the phase I/II or phase III trials and were continuing to receive treatment after completion of the trials were invited to participate in a comprehensive evaluation visit to assess long-term outcomes. Primary endpoints were changes in serum oligosaccharide and the 3-minute stair climb test (3MSCT). Mean (SD) treatment exposure was 29.3 (15.2) months. Serum oligosaccharide levels were significantly reduced in the overall population at 12 months (mean change: -72.7%, P < 0.001) and remained statistically significant at last observation (-62.8%, P < 0.001). A mean improvement of +9.3% in 3MSCT was observed at 12 months (P = 0.013), which also remained statistically significant at last observation (+13.8%, P = 0.004), with a more pronounced improvement detected in the paediatric subgroup. No treatment-emergent adverse events were reported leading to permanent treatment discontinuation. Patients treated with velmanase alfa experienced improvements in biochemical and functional measures that were maintained for up to 4 years. Long term follow-up is important and further supports the use of velmanase alfa as an effective and well-tolerated treatment for AM. Based on the currently available data set, no baseline characteristic can be predictive of treatment outcome. Early treatment during paediatric age showed better outcome in functional endpoints.

Diabetes is a complex metabolic disease that exposes patients to the deleterious effects of hyperglycemia on various organs. Achievement of normoglycemia with exogenous insulin treatment requires the use of high doses of hormone, which increases the risk of life-threatening hypoglycemic episodes. We developed a gene therapy approach to control diabetic hyperglycemia based on co-expression of the insulin and glucokinase genes in skeletal muscle. Previous studies proved the feasibility of gene delivery to large diabetic animals with adeno-associated viral (AAV) vectors. Here, we report the long-term (∼8 years) follow-up after a single administration of therapeutic vectors to diabetic dogs. Successful, multi-year control of glycemia was achieved without the need of supplementation with exogenous insulin. Metabolic correction was demonstrated through normalization of serum levels of fructosamine, triglycerides, and cholesterol and remarkable improvement in the response to an oral glucose challenge. The persistence of vector genomes and therapeutic transgene expression years after vector delivery was documented in multiple samples from treated muscles, which showed normal morphology. Thus, this study demonstrates the long-term efficacy and safety of insulin and glucokinase gene transfer in large animals and especially the ability of the system to respond to the changes in metabolic needs as animals grow older.

Background. The Shingles Prevention Study (SPS) demonstrated zoster vaccine efficacy through 4 years postvaccination. A Short-Term Persistence Substudy (STPS) demonstrated persistence of vaccine efficacy for at least 5 years. A Long-Term Persistence Substudy (LTPS) was undertaken to further assess vaccine efficacy in SPS vaccine recipients followed for up to 11 years postvaccination. Study outcomes were assessed for the entire LTPS period and for each year from 7 to 11 years postvaccination. Methods. Surveillance, case determination, and follow-up were comparable to those in SPS and STPS. Because SPS placebo recipients were offered zoster vaccine before the LTPS began, there were no unvaccinated controls. Instead, SPS and STPS placebo results were used to model reference placebo groups. Results. The LTPS enrolled 6867 SPS vaccine recipients. Compared to SPS, estimated vaccine efficacy in LTPS decreased from 61.1% to 37.3% for the herpes zoster (HZ) burden of illness (BOI), from 66.5% to 35.4% for incidence of postherpetic neuralgia, and from 51.3% to 21.1% for incidence of HZ, and declined for all 3 outcome measures from 7 through 11 years postvaccination. Vaccine efficacy for the HZ BOI was significantly greater than zero through year 10 postvaccination, whereas vaccine efficacy for incidence of HZ was significantly greater than zero only through year 8. Conclusions. Estimates of vaccine efficacy decreased over time in the LTPS population compared with modeled control estimates. Statistically significant vaccine efficacy for HZ BOI persisted into year 10 postvaccination, whereas statistically significant vaccine efficacy for incidence of HZ persisted only through year 8.

The round window (RW) approach in the use of the Vibrant Soundbridge(®) (VSB) is a safe and effective treatment of conductive and mixed hearing losses for a period of more than 3 years of device use. To investigate the long-term safety and efficacy as well as user satisfaction of patients with conductive and mixed hearing losses implanted with the VSB using RW vibroplasty. Twelve patients with conductive and mixed hearing losses were evaluated after 40 months of daily VSB use. Safety was assessed by evaluating reports of postoperative medical and surgical complications as well as by changes in bone conduction hearing thresholds. Efficacy outcome measures included aided and unaided hearing thresholds, speech recognition in quiet and in noise and subjective benefit questionnaires. The safety results revealed no significant medical complications. One subject experienced sudden hearing loss after 18-24 months of device use, but still continues to wear the device to her satisfaction. With regard to efficacy, there were no significant changes from short- to long-term results in aided word understanding, functional gain or speech recognition threshold, suggesting that the outcomes are stable over time. Subjective questionnaires revealed either the same or better results compared with the short-term data.

What are the major security/safety problems of long term care facilities? What steps are being taken by some facilities to mitigate such problems? Answers to these questions can be found in a survey of IAHSS members involved in long term care security conducted for the IAHSS Long Term Care Security Task Force. The survey, the author points out, focuses primarily on long term care facilities operated by hospitals and health systems. However, he believes, it does accurately reflect the security problems most long term facilities face, and presents valuable information on security systems and practices which should be also considered by independent and chain operated facilities.

Historically, chronic pain generally went under-treated for a variety of objective and subjective reasons, including difficulty to objectively diagnose and manage over a long period of time, potential serious adverse effects of commonly available medications, and patient, healthcare and societal concerns over opioid medications. More recently, in an effort to redress the under-treatment of pain, the number of prescriptions of opioid analgesics has risen dramatically. However, paralleling the increased legitimate use has been a concomitant increase in opioid abuse, misuse and diversion. Pharmaceutical companies have responded by developing a variety of opioid formulations designed to deter abuse by making the products more difficult to tamper with. One such product is Remoxy(®), an extended-release formulation of the strong opioid oxycodone. We review the efficacy, safety and tolerability of this formulation based on the available published literature.

Non-steroidal anti-inflammatory drugs (NSAIDs) are an effective and common treatment for chronic pain disorders, but long-term use is associated with risk of potentially life-threatening gastrointestinal adverse events (AEs). The proton pump inhibitor esomeprazole has been found to be effective for gastroprotection in NSAID users, but few long-term studies have been conducted in Japan. This was an open-label, multicentre, single-arm, prospective 1-year study of treatment with esomeprazole (20 mg once daily) in Japanese patients (aged ≥20 years) with endoscopic evidence of previous peptic ulcer and receiving daily oral NSAID therapy (at a stable dose) for a chronic condition. Eligibility was not dictated by type of oral NSAID. The primary objective was to determine long-term safety and tolerability of esomeprazole. Efficacy for prevention of peptic ulcers was also determined (Kaplan-Meier method). All statistical analyses were descriptive. A total of 130 patients (73.1% women, mean age 62.1 years, 43.8% Helicobacter pylori-positive) received treatment with esomeprazole in addition to long-term NSAID therapy (most commonly for rheumatoid arthritis [n=42] and osteoarthritis [n=34]). Loxoprofen, meloxicam and diclofenac were the most commonly used NSAIDs; cyclo-oxygenase (COX)-2 selective agents were used by 16.2% of patients (n=21). Long-term compliance with esomeprazole (capsule counts) was >75% for the majority of patients. Although 16.9% of patients (n=22) experienced AEs judged to be possibly related to treatment with esomeprazole, they were mostly mild and transient. The most commonly reported possibly treatment-related AEs were abnormal hepatic function, headache, increased γ-glutamyltransferase levels and muscle spasms (2 patients each). Overall, 95.9% (95% confidence interval: 92.3, 99.4) of patients remained ulcer free at 1 year. Long-term treatment with esomeprazole (20 mg once daily) is well tolerated and efficacious for preventing ulcer recurrence in

Objective We herein conducted a retrospective study to evaluate the long-term efficacy and safety of sitagliptin treatment in elderly patients with type 2 diabetes mellitus. Methods We analyzed the changes in glycemic control in 112 Japanese type 2 diabetes patients over 65 years of age treated with 50 mg/day sitagliptin. Hemoglobin A1c (HbA1c) levels, liver and kidney functions, and usage of hypoglycemic agents were recorded for 24 months. Results HbA1c levels were significantly decreased, and the significance of HbA1c reduction was maintained during the observation period [from 7.7±1.1% to 7.2±0.7% (p<0.001) at the end of observational period]. The %change in HbA1c levels was significantly and negatively correlated with the baseline HbA1c levels (r=-0.51, p<0.001), but not with age, duration of diabetes, or the estimated glomerular filtration rate (eGFR). No patient experienced severe hypoglycemia episodes, and aspartate transaminase, alanine transaminase, gamma-glutamyl transpeptidase, and the eGFR remained unchanged. The dose of sulfonylurea was finally decreased in 72% of patients treated with sulfonylurea. Conclusion Sitagliptin treatment continually decreases the HbA1c level for 24 months and is useful to reduce the dose of sulfonylurea in elderly patients with type 2 diabetes.

The combination of all-trans retinoic acid (ATRA) and arsenic trioxide (As2O3, ATO) has been effective in obtaining high clinical complete remission (CR) rates in acute promyelocytic leukemia (APL), but the long-term efficacy and safety among newly diagnosed APL patients are unclear. In this retrospective study, total 45 newly diagnosed APL patients received ATRA/chemotherapy combination regimen to induce remission. Among them, 43 patients (95.6%) achieved complete remission (CR) after induction therapy, followed by ATO/ATRA/anthracycline-based chemotherapy sequential consolidation treatment with a median follow-up of 55 months. In these patients, the estimated overall survival (OS) and the relapse-free survival (RFS) were 94.4% ± 3.9% and 94.6 ± 3.7%, respectively. The toxicity profile was mild and reversible. No secondary carcinoma was observed. These results demonstrated the high efficacy and minimal toxicity of ATO/ATRA/anthracycline-based chemotherapy sequential consolidation treatment for newly diagnosed APL in long-term follow-up, suggesting a potential frontline therapy for APL.

Long-term opioid treatment of chronic nonmalignant pain: unproven efficacy and neglected safety?

PubMed Central

Kissin, Igor

2013-01-01

Background For the past 30 years, opioids have been used to treat chronic nonmalignant pain. This study tests the following hypotheses: (1) there is no strong evidence-based foundation for the conclusion that long-term opioid treatment of chronic nonmalignant pain is effective; and (2) the main problem associated with the safety of such treatment – assessment of the risk of addiction – has been neglected. Methods Scientometric analysis of the articles representing clinical research in this area was performed to assess (1) the quality of presented evidence (type of study); and (2) the duration of the treatment phase. The sufficiency of representation of addiction was assessed by counting the number of articles that represent (1) editorials; (2) articles in the top specialty journals; and (3) articles with titles clearly indicating that the addiction-related safety is involved (topic-in-title articles). Results Not a single randomized controlled trial with opioid treatment lasting >3 months was found. All studies with a duration of opioid treatment ≥6 months (n = 16) were conducted without a proper control group. Such studies cannot provide the consistent good-quality evidence necessary for a strong clinical recommendation. There were profound differences in the number of addiction articles related specifically to chronic nonmalignant pain patients and to opioid addiction in general. An inadequate number of chronic pain-related publications were observed with all three types of counted articles: editorials, articles in the top specialty journals, and topic-in-title articles. Conclusion There is no strong evidence-based foundation for the conclusion that long-term opioid treatment of chronic nonmalignant pain is effective. The above identified signs indicating neglect of addiction associated with the opioid treatment of chronic nonmalignant pain were present. PMID:23874119

Taliglucerase alfa is an intravenous enzyme replacement therapy approved for treatment of type 1 Gaucher disease (GD), and is the first available plant cell-expressed recombinant therapeutic protein. Herein, we report long-term safety and efficacy results of taliglucerase alfa in treatment-naïve adult patients with GD. Patients were randomized to receive taliglucerase alfa 30 or 60 U/kg every other week, and 23 patients completed 36 months of treatment. Taliglucerase alfa (30 U/kg; 60 U/kg, respectively) resulted in mean decreases in spleen volume (50.1%; 64.6%) and liver volume (25.6%; 24.4%) with mean increases in hemoglobin concentration (16.0%; 35.8%) and platelet count (45.7%; 114.0%), and mean decreases in chitotriosidase activity (71.5%; 82.2%). All treatment-related adverse events were mild to moderate in intensity and transient. The most common adverse events were nasopharyngitis, arthralgia, upper respiratory tract infection, headache, pain in extremity, and hypertension. These 36-month results of taliglucerase alfa in treatment-naïve adult patients with GD demonstrate continued improvement in disease parameters with no new safety concerns. These findings extend the taliglucerase alfa clinical safety and efficacy dataset. www.clinicaltrials.gov identifier NCT00705939. Am. J.

Sacral nerve stimulation is effective in the treatment of urinary incontinence and is currently under Food and Drug Administration review in the United States for fecal incontinence. Previous reports have focused primarily on short-term results of sacral nerve stimulation for fecal incontinence. The present study reports the long-term effectiveness and safety of sacral nerve stimulation for fecal incontinence in a large prospective multicenter study. Patients with fecal incontinent episodes more than twice per week were offered participation in this multicentered prospective trial. Patients showing ≥ 50% improvement during test stimulation were offered chronic implantation of the InterStim Therapy system (Medtronic; Minneapolis, MN). The aims of the current report were to provide 3-year follow-up data on patients from that study who underwent sacral nerve stimulation and were monitored under the rigors of an Food and Drug Administration-approved investigational protocol. One hundred thirty-three patients underwent test stimulation with a 90% success rate, of whom 120 (110 females) with a mean age of 60.5 years and a mean duration of fecal incontinence of 7 years received chronic implantation. Mean length of follow-up was 3.1 (range, 0.2-6.1) years, with 83 patients completing all or part of the 3-year follow-up assessment. At 3 years follow-up, 86% of patients (P < .0001) reported ≥ 50% reduction in the number of incontinent episodes per week compared with baseline and the number of incontinent episodes per week decreased from a mean of 9.4 at baseline to 1.7. Perfect continence was achieved in 40% of subjects. The therapy also improved the fecal incontinence severity index. Sacral nerve stimulation had a positive impact on the quality of life, as evidenced by significant improvements in all 4 scales of the Fecal Incontinence Quality of Life instrument at 12, 24, and 36 months of follow-up.

Aspirin hypersensitivity is not a rare condition among patients with acute coronary syndrome. However, despite the publication of several successful desensitization protocols, the procedure is not as widespread as expected. We present a cohort of patients with acute coronary syndrome undergoing aspirin desensitization to evaluate its short- and long-term efficacy and safety and to reinforce data from previous studies. Of 1306 patients admitted to our Coronary Care Unit between February 2011 and February 2013, 24 (1.8%) had a history of aspirin hypersensitivity. All 24 patients underwent an eight-dose aspirin desensitization protocol (0.1, 0.3, 1, 3, 10, 25, 50 and 100 mg of aspirin given by mouth every 15 minutes) after premedication with antihistamines and corticosteroids or antileucotrienes. Previously prescribed β blockers and angiotensin-converting enzyme inhibitors were not discontinued. All patients were desensitized within 72 hours of admission. Those requiring urgent catheterization (five patients with ST segment elevation myocardial infarction) were desensitized within 12 hours of catheterization and the remainder before catheterization. All patients were successfully desensitized and only one presented with an urticarial reaction. The five patients with ST segment elevation myocardial infarction were treated with abciximab until desensitization was complete. All but one patient underwent catheterization and 20 underwent percutaneous coronary intervention, most (66%) with the implantation of a bare metal stent. At follow-up (a minimum of 6-24 months), only two patients had discontinued aspirin, both due to gastrointestinal bleeding, and no hypersensitivy reaction had occurred. Aspirin desensitization is effective and safe in unstable patients with acute coronary syndrome in both the short and long term.

To evaluate the efficacy and safety of extended dosing with mipomersen in patients with familial hypercholesterolaemia (HC) taking maximally tolerated lipid-lowering therapy. A planned interim analysis of an ongoing, open-label extension trial in patients (n = 141) with familial HC receiving a subcutaneous injection of 200 mg mipomersen weekly plus maximally tolerated lipid-lowering therapy for up to 104 weeks. The mean changes in low-density lipoprotein cholesterol (LDL-C) from baseline to weeks 26 (n = 130), 52 (n = 111), 76 (n = 66), and 104 (n = 53) were -28, -27, -27, and -28%; and in apolipoprotein B -29, -28, -30, and -31%, respectively. Reductions in total cholesterol, non-high-density lipoprotein-cholesterol, and lipoprotein(a) were comparable with decreases in LDL-C and apolipoprotein B levels. Mean high-density lipoprotein cholesterol increased from baseline by 7 and 6% at weeks 26 and 52, respectively. The long-term safety profile of mipomersen was similar to that reported in the associated randomized placebo-controlled Phase 3 trials. Adverse events included injection site reactions and flu-like symptoms. There was an incremental increase in the median liver fat during the initial 6-12 months that appeared to diminish with continued mipomersen exposure beyond 1 year and returned towards baseline 24 weeks after last drug dose suggestive of adaptation. The median alanine aminotransferase level showed a similar trend over time. Long-term treatment with mipomersen for up to 104 weeks provided sustained reductions in all atherosclerotic lipoproteins measured and a safety profile consistent with prior controlled trials in these high-risk patient populations.

Safety and efficacy of long-term esomeprazole 20 mg in Japanese patients with a history of peptic ulcer receiving daily non-steroidal anti-inflammatory drugs

PubMed Central

2013-01-01

Background Non-steroidal anti-inflammatory drugs (NSAIDs) are an effective and common treatment for chronic pain disorders, but long-term use is associated with risk of potentially life-threatening gastrointestinal adverse events (AEs). The proton pump inhibitor esomeprazole has been found to be effective for gastroprotection in NSAID users, but few long-term studies have been conducted in Japan. Methods This was an open-label, multicentre, single-arm, prospective 1-year study of treatment with esomeprazole (20 mg once daily) in Japanese patients (aged ≥20 years) with endoscopic evidence of previous peptic ulcer and receiving daily oral NSAID therapy (at a stable dose) for a chronic condition. Eligibility was not dictated by type of oral NSAID. The primary objective was to determine long-term safety and tolerability of esomeprazole. Efficacy for prevention of peptic ulcers was also determined (Kaplan-Meier method). All statistical analyses were descriptive. Results A total of 130 patients (73.1% women, mean age 62.1 years, 43.8% Helicobacter pylori-positive) received treatment with esomeprazole in addition to long-term NSAID therapy (most commonly for rheumatoid arthritis [n=42] and osteoarthritis [n=34]). Loxoprofen, meloxicam and diclofenac were the most commonly used NSAIDs; cyclo-oxygenase (COX)-2 selective agents were used by 16.2% of patients (n=21). Long-term compliance with esomeprazole (capsule counts) was >75% for the majority of patients. Although 16.9% of patients (n=22) experienced AEs judged to be possibly related to treatment with esomeprazole, they were mostly mild and transient. The most commonly reported possibly treatment-related AEs were abnormal hepatic function, headache, increased γ-glutamyltransferase levels and muscle spasms (2 patients each). Overall, 95.9% (95% confidence interval: 92.3, 99.4) of patients remained ulcer free at 1 year. Conclusion Long-term treatment with esomeprazole (20 mg once daily) is well tolerated and

Intestinal Behçet's disease (BD) is an immune-mediated inflammatory disorder. We followed up the patients and evaluated safety profile and effectiveness of adalimumab for the treatment of intestinal BD through 100 weeks rolled over from the 52 week clinical trial (NCT01243671). Patients initiated adalimumab therapy at 160 mg at week 0, followed by 80 mg at week 2, followed by 40 mg every other week until the end of the study. Long-term safety and all adverse events (AEs) were examined. The efficacy was assessed on the basis of marked improvement (MI) and complete remission (CR) using a composite efficacy index, which combined global gastrointestinal symptoms and endoscopic assessments. Twenty patients were enrolled in this study; 15 patients received adalimumab treatment until study completion. The incidence of AEs through week 100 was 544.4 events/100 person-years, which was comparable to the incidence through week 52 (560.4 events/100 person-years). No unexpected trend was observed and adalimumab was well tolerated. At weeks 52 and 100, 60.0% and 40.0% of patients showed MI, respectively, and 20.0% and 15.0% of patients showed CR, respectively. This report demonstrates 2 years safety and effectiveness of adalimumab in intestinal BD patients. Patients with intestinal BD refractory to conventional treatment receiving up to 2 years of adalimumab treatment demonstrated safety outcomes consistent with the known profile of adalimumab, and the treatment led to sustained reduction of clinical and endoscopic disease activity.

These studies were undertaken to determine if fexapotide triflutate 2.5 mg transrectal injectable (FT) has significant long-term (LT) safety and efficacy for the treatment of benign prostatic hyperplasia (BPH). Two placebo controlled double-blind randomized parallel group trials with 995 BPH patients at 72 sites treated 3:2 FT:placebo, with open-label FT crossover (CO) re-injection in 2 trials n = 344 and long-term follow-up (LF) 2-6.75 years (mean 3.58 years, median 3.67 years; FT re-injection CO mean 4.27 years, median 4.42 years) were evaluated. 12 months post-treatment patients elected no further treatment, approved oral medications, FT, or interventional treatment. Primary endpoint variable was change in Symptom Score (IPSS) at 12 months and at LF. CO primary co-endpoints were 3-year incidence of (1) surgery for BPH in FT treated CO patients versus patients crossed over to oral BPH medications and (2) surgery or acute urinary retention in FT-treated CO placebo patients versus placebo patients crossed over to oral BPH medications. 28 CO secondary endpoints assessed surgical and symptomatic outcomes in FT reinjected patients versus conventional BPH medication CO and control subgroups at 2 and 3 years. FT injection had no significant safety differences from placebo. LF IPSS change from baseline was higher in FT treated patients compared to placebo (median FT group improvement - 5.2 versus placebo - 3.0, p < 0.0001). LF incidence of AUR (1.08% p = 0.0058) and prostate cancer (PCa) (1.1% p = 0.0116) were both reduced in FT treated patients. LF incidence of intervention for BPH was reduced in the FT group versus oral BPH medications (8.08% versus 27.85% at 3 years, p < 0.0001). LF incidence of intervention or AUR in placebo CO group with FT versus placebo CO group with oral medications was reduced (6.07% versus 33.3% at 3 years, p < 0.0001). 28/28 secondary efficacy endpoints were reached in LF CO re-injection studies.

To date, anti-tumor necrosis factor alfa (anti-TNF-α) therapy is the only alternative to nonsteroidal anti-inflammatory drugs for the treatment of ankylosing spondylitis. Etanercept is a soluble TNF receptor, with a mode of action and pharmacokinetics different to those of antibodies and distinctive efficacy and safety. Etanercept has demonstrated efficacy in the treatment of ankylosing spondylitis, with or without radiographic sacroiliitis, and other manifestations of the disease, including peripheral arthritis, enthesitis, and psoriasis. Etanercept is not efficacious in inflammatory bowel disease, and its efficacy in the treatment of uveitis appears to be lower than that of other anti-TNF drugs. Studies of etanercept confirmed regression of bone edema on magnetic resonance imaging of the spine and sacroiliac joint, but failed to reduce radiographic progression, as do the other anti-TNF drugs. It seems that a proportion of patients remain in disease remission when the etanercept dose is reduced or administration intervals are extended. Etanercept is generally well tolerated with an acceptable safety profile in the treatment of ankylosing spondylitis. The most common adverse effect of etanercept treatment is injection site reactions, which are generally self-limiting. Reactivation of tuberculosis, reactivation of hepatitis B virus infection, congestive heart failure, demyelinating neurologic disorders, hematologic disorders like aplastic anemia and pancytopenia, vasculitis, immunogenicity, and exacerbation or induction of psoriasis are class effects of all the anti-TNF drugs, and have been seen in patients with ankylosing spondylitis. However, etanercept is less likely to induce reactivation of tuberculosis than the other anti-TNF drugs and it has been suggested that etanercept might be less immunogenic, especially in ankylosing spondylitis. Acute uveitis, Crohn’s disease, and sarcoidosis are other adverse events that have been rarely associated with etanercept

A regimen with rilpivirine (RPV), abacavir (ABC) and lamivudine (3TC) is simple and may allow the sparing of tenofovir and protease inhibitors. However, data on use of this combination as a strategy of switch are limited. Aims of the study were to assess the long-term efficacy and safety of this regimen. Retrospective study on HIV-1 infected patients followed at the Infectious Disease Department of the San Raffaele Scientific Institute, HBsAg-negative, HLA B5701-negative, with no documented resistance to RPV, ABC and 3TC, with HIV-RNA<50 copies/mL who started RPV plus ABC/3TC from March 2013 to September 2015. The primary outcome was durability [no treatment failure (TF)]. Secondary objectives were to evaluate changes in immunological, metabolic and other safety parameters. TF was defined as the occurrence of virological failure (VF, 2 consecutive values >50 copies/mL) or discontinuation of any drug in the regimen for any reason. Patients' follow-up accrued from the date of RPV plus ABC/3TC initiation to the date of TF (VF or discontinuation of any drug in the regimen) or to the date of last available visit. Time to TF was evaluated by use of the Kaplan-Meier curves. Mixed linear models were applied to evaluate changes in immunological, metabolic and other safety parameters. In this analysis, 100 patients starting RPV plus ABC/3TC were included. By 12, 24 and 36 months after switching to RPV plus ABC/3TC, the proportions of individuals without TF were 88% [95% confidence interval (CI): 79%-93%], 82% (95% CI:73%-89%) and 78% (95% CI:68%-86%), respectively. Time to TF was not significantly influenced by CD4+ nadir (≤200 vs >200 cells/μl; log-rank test: p = 0.311) or pre-ART viral load (<100000 vs ≥100000 copies/mL; log-rank test: p = 0.574) or the type of previous antiretroviral regimen (PI+2NRTIs vs NNRTI+2NRTIs vs Other; log-rank test: p = 0.942).

Proton pump inhibitors (PPIs) are among the most widely prescribed medications worldwide. Their use has resulted in dramatic improvements in treatment of peptic ulcer disease and gastroesophageal reflux disease. Despite an acceptable safety profile, mounting data demonstrate concerns about the long-term use of PPIs. To provide a comprehensive review regarding the concerns of long-term PPI use, a literature search was performed to identify pertinent original and review articles. Despite study shortcomings, the collective body of information overwhelmingly suggests an increased risk of infectious complications and nutritional deficiencies. Data regarding any increased risk in gastric or colon malignancy are less convincing. PPIs have revolutionized the management and complications of acid-related disorders with a high margin of safety; however, with the data available, efforts to reduce the dosing of or discontinue the use of PPIs must be reassessed frequently.

The purpose of this study was to determine the long-term efficacy and safety of valproic acid (VPA) treatment in patients with pigmentary retinal dystrophies. A retrospective chart review was conducted on 31 patients with a diagnosis of pigmentary retinal dystrophy prescribed VPA at a single centre. Visual field (VF), visual acuity (VA), length of treatment, liver enzymes and side effects were analysed. VF areas were defined using Goldmann VF (GVF) tracings recorded before, during and after VPA treatment using the V4e isopter for each eye. Using custom software, planimetric areas of VF were calculated. Five of the patients (10 eyes) had two Goldmann VF tracings, allowing comparison between baseline and follow-up VF. After 9.8 months of VPA, VF decreased by 0.145 cm(2) (26.478%) (p=0.432). For 22 of the patients (41 eyes), VA data was available, and logarithm of the minimum angle of resolution (logMAR) score changed by 0.056 log units (representing a decline in VA) after 14.9 months on VPA (p=0.002). Twelve patients (38.7%) reported negative side effects related to VPA use. VPA plays a complex role in patients with pigmentary retinal dystrophies and may be associated with VA and field decline as well as adverse side effects. Physicians should use caution with using VPA for pigmentary retinal dystrophies.

Hereditary angioedema (HAE) is characterized by recurrent attacks of subcutaneous or submucosal edema. Attacks are unpredictable, debilitating, and have a significant impact on quality of life. Patients may be prescribed prophylactic therapy to prevent angioedema attacks. Current prophylactic treatments may be difficult to administer (i.e., intravenously), require frequent administrations or are not well tolerated, and breakthrough attacks may still occur frequently. Lanadelumab is a subcutaneously-administered monoclonal antibody inhibitor of plasma kallikrein in clinical development for prophylaxis of hereditary angioedema attacks. A Phase 1b study supported its efficacy in preventing attacks. A Phase 3, randomized, double-blind, placebo-controlled, parallel-arm study has been completed and an open-label extension is currently ongoing. The primary objective of the open-label extension is to evaluate the long-term safety of repeated subcutaneous administrations of lanadelumab in patients with type I/II HAE. Secondary objectives include evaluation of efficacy and time to first angioedema attack to determine outer bounds of the dosing interval. The study will also evaluate immunogenicity, pharmacokinetics/pharmacodynamics, quality of life, characteristics of breakthrough attacks, ease of self-administration, and safety/efficacy in patients who switch to lanadelumab from another prophylactic therapy. The open-label extension will enroll patients who completed the double-blind study ("rollover patients") and those who did not participate in the double-blind study ("non-rollover patients"), which includes patients who may or may not be currently using another prophylactic therapy. Rollover patients will receive a single 300 mg dose of lanadelumab on Day 0 and the second dose after the patient's first confirmed angioedema attack. Thereafter, lanadelumab will be administered every 2 weeks. Non-rollover patients will receive 300 mg lanadelumab every 2 weeks regardless

We undertook this US multicenter continuation study (GlaxoSmithKline study BEL112233; ClinicalTrials.gov identifier: NCT00724867) to assess long-term safety and efficacy of belimumab in patients with systemic lupus erythematosus (SLE) who completed the Study of Belimumab in Subjects with SLE 76-week trial (ClinicalTrials.gov identifier: NCT00410384). Patients continued to receive the same belimumab dose plus standard therapy; patients previously receiving placebo received 10 mg/kg belimumab. The primary outcome measure was long-term safety of belimumab (frequency of adverse events [AEs] and damage assessed using the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index [SDI], evaluated every 48 weeks [1 study year]). Other assessments included the SLE Responder Index (SRI), flare rates (using the modified SLE Flare Index [SFI]), prednisone use, and B cell levels. Of 268 patients, 140 completed the study and 128 withdrew. The mean ± SD score on the Safety of Estrogens in Lupus Erythematosus National Assessment version of the SLE Disease Activity Index (SELENA-SLEDAI) at baseline was 7.8 ± 3.86. The mean ± SD SDI score increased by 0.4 ± 0.68 from its value at baseline (1.2 ± 1.51). The overall incidence of treatment-related and serious AEs remained stable or declined through study year 7. An SRI response was achieved by 41.9% and 75.6% of patients at the study year 1 and study year 7 midpoints, respectively. At the study year 7 midpoint, relative to baseline, 78.2% had achieved a ≥4-point reduction in the SELENA-SLEDAI score, 98.4% had no new British Isles Lupus Assessment Group (BILAG) A organ domain score and no more than 1 new BILAG B organ domain score, 93.7% had no worsening in the physician's global assessment of disease activity, 20.6% had experienced ≥1 severe SFI flare, the mean decrease in prednisone dose was 31.4%, and the median change in CD20+ B cell numbers was -83.2%.

PV reconnection is often the result of catheter instability and tissue edema. High-power short-duration (HP-SD) ablation strategies have been shown to improve atrial linear continuity in acute pre-clinical models. This study compares the safety, efficacy and long-term durability of HP-SD ablation with conventional ablation. In 6 swine, 2 ablation lines were performed anterior and posterior to the crista terminalis, in the smooth and trabeculated right atrium, respectively; and the right superior PV was isolated. In 3 swine, ablation was performed using conventional parameters (THERMOCOOL-SMARTTOUCH ® SF; 30W/30 sec) and in 3 other swine using HP-SD parameters (QDOT-MICRO™, 90W/4 sec). After 30 days, linear integrity was examined by voltage mapping and pacing, and the heart and surrounding tissues were examined by histopathology. Acute line integrity was achieved with both ablation strategies; however, HP-SD ablation required 80% less RF time compared with conventional ablation (P≤0.01 for all lines). Chronic line integrity was higher with HP-SD ablation: all 3 posterior lines were continuous and transmural compared to only 1 line created by conventional ablation. In the trabeculated tissue, HP-SD ablation lesions were wider and of similar depth with 1 of 3 lines being continuous compared to 0 of 3 using conventional ablation. Chronic PVI without stenosis was evident in both groups. There were no steam-pops. Pleural markings were present in both strategies, but parenchymal lung injury was only evident with conventional ablation. HP-SD ablation strategy results in improved linear continuity, shorter ablation time, and a safety profile comparable to conventional ablation. This article is protected by copyright.

Long-term safety and efficacy of raloxifene in the prevention and treatment of postmenopausal osteoporosis: an update

PubMed Central

Messalli, Enrico M; Scaffa, Cono

2010-01-01

The integrity of bone tissue and its remodeling that occurs throughout life requires a coordinated activity of osteoblasts and osteoclasts. The decreased estrogen circulating level during postmenopausal transition, with a prevalence of osteoclastic activity over osteoblastic activity, represents the main cause of bone loss and osteoporosis. Osteoporosis is a chronic disease requiring long-term therapy and it is important to evaluate the efficacy and safety of treatments over several years, as the fear of health risks is a common reason for discontinuing therapy. Raloxifene is a selective estrogen receptor modulator (SERM) leading to estrogen-agonist effects in some tissues and estrogen-antagonist effects in others. Raloxifene is effective to prevent and treat postmenopausal vertebral osteoporosis, with reduction of spine fractures and, in post-hoc analyses, non-spine fractures in high-risk subjects. Moreover, raloxifene reduces the risk of invasive breast cancer and improves the levels of serum lipoprotein but with an increased risk of venous thromboembolism and fatal stroke, without significant change in the incidence of coronary events. For these reasons the overall risk-benefit profile is favorable. Therefore, when considering the use of raloxifene in a postmenopausal woman, we should take into account the osteoporosis-related individual risk and weigh the potential benefits, skeletal and extra-skeletal, against the health risks.

Gamma Knife surgery (GKS) is one of the surgical alternatives for the treatment of drug-resistant trigeminal neuralgia (TN). This study aims to evaluate the safety and efficacy of GKS in a large population of patients with TN with very long-term clinical follow-up. Between July 1992 and November 2010, 737 patients presenting with TN were treated using GKS. Data were collected prospectively and were further retrospectively evaluated at Timone University Hospital. The frequency and severity of pain, as well as trigeminal nerve function, were evaluated before GKS and regularly thereafter. Radiosurgery using the Gamma Knife (model B, C, 4C, or Perfexion) was performed with the help of both MR and CT targeting. A single 4-mm isocenter was positioned in the cisternal portion of the trigeminal nerve at a median distance of 7.6 mm (range 4-14 mm) anterior to the emergence of the nerve (retrogasserian target). A median maximum dose of 85 Gy (range 70-90 Gy) was prescribed. The safety and efficacy are reported for 497 patients with medically refractory classical TN who were never previously treated by GKS and had a follow-up of at least 1 year. The median age in this series was 68.3 years (range 28.1-93.2 years). The median follow-up period was 43.8 months (range 12-174.4 months). Overall, 456 patients (91.75%) were initially pain free in a median time of 10 days (range 1-180 days). Their actuarial probabilities of remaining pain free without medication at 3, 5, 7, and 10 years were 71.8%, 64.9%, 59.7%, and 45.3%, respectively. One hundred fifty-seven patients (34.4%) who were initially pain free experienced at least 1 recurrence, with a median delay of onset of 24 months (range 0.6-150.1 months). However, the actuarial rate of maintaining pain relief without further surgery was 67.8% at 10 years. The hypesthesia actuarial rate at 5 years was 20.4% and at 7 years reached 21.1%, but remained stable until 14 years with a median delay of onset of 12 months (range 1-65 months

To evaluate the safety and long-term efficacy of fractional CO 2 laser treatment in reducing the severity of symptoms of genitourinary syndrome of menopause (GSM) in menopausal women. 102 women presenting with symptomatic GSM were treated with the fractional CO 2 laser (MonaLisa Touch, DEKA) system across a series of treatments delivered at intervals of six or more weeks. The Australian Pelvic Floor Questionnaire was used to gather data on sexual function and side-effects at three time-points across the study period (prospective panel design study). Wilcoxon signed-rank tests were used to detect statistically and clinically significant changes in sexual function and side-effects occurring from pre- to post-treatment. The primary outcome of this study was an improvement of the symptoms of GSM. The secondary outcome included bladder function and prolapse symptoms. A total of 102 women suffering from moderate to severe GSM were recruited. Eighty-four percent experienced significant improvement in their symptoms after CO 2 laser treatment. Scores on measures of sexual function, dyspareunia, and bothersomeness of sexual issues were improved from pre-treatment to long-term (12-24 month) follow-up. Furthermore, there were improvements on measures of bladder function (P=0.001), prolapse (P=0.001), vaginal sensation (P=0.001), vaginal lubrication (P<0.001) and urge incontinence (P=0.003) from the pre-treatment assessment to the second assessment (i.e. after the third treatment). In this study, fractional microablative CO 2 laser treatment was associated with an improvement in symptoms of GSM and sexual function. Copyright © 2017. Published by Elsevier B.V.

Viral mediated gene therapy has progressed after overcoming early failures, and gene therapy has now been approved for several conditions in Europe and the USA. Glycogen storage disease (GSD) type Ia, caused by a deficiency of glucose-6-phosphatase-α, has been viewed as an outstanding candidate for gene therapy. This follow-up report describes the long-term outcome for the naturally occurring GSD-Ia dogs treated with rAAV-GPE-hG6PC-mediated gene therapy. A total of seven dogs were treated with rAAV-GPE-hG6PC-mediated gene therapy. The first four dogs were treated at birth, and three dogs were treated between 2 and 6 months of age to assess the efficacy and safety in animals with mature livers. Blood and urine samples, radiographic studies, histological evaluation, and biodistribution were assessed. Gene therapy improved survival in the GSD-Ia dogs. With treatment, the biochemical studies normalized for the duration of the study (up to 7 years). None of the rAAV-GPE-hG6PC-treated dogs had focal hepatic lesions or renal abnormalities. Dogs treated at birth required a second dose of rAAV after 2-4 months; gene therapy after hepatic maturation resulted in improved efficacy after a single dose. rAAV-GPE-hG6PC treatment in GSD-Ia dogs was found to be safe and efficacious. GSD-Ia is an attractive target for human gene therapy since it is a monogenic disorder with limited tissue involvement. Blood glucose and lactate monitoring can be used to assess effectiveness and as a biomarker of success. GSD-Ia can also serve as a model for other hepatic monogenic disorders.

Children with red blood cell disorders may receive regular transfusions from an early age and consequently accumulate iron. Adequate iron chelation therapy can prevent organ damage and delayed growth/development. Deferasirox is indicated for treatment of pediatric patients with chronic iron overload due to transfusional hemosiderosis; however, fewer than 10% of patients in the registration studies were aged 2 to less than 6 years. Deferasirox, a once-daily oral iron chelator, was evaluated in young pediatric patients with transfusional hemosiderosis during the observational 5-year ENTRUST study. Patients aged 2 to less than 6 years at enrollment received deferasirox according to local prescribing information, with the primary objective of evaluating safety, specifically renal and hepatic function. Serum ferritin was observed as a surrogate efficacy parameter. In total, 267 patients (mean age 3.2 years) predominantly with β-thalassemia (n = 176, 65.9%) were enrolled. Mean ± standard deviation deferasirox dose was 25.8 ± 6.5 mg/kg per day over a median of 59.9 months. A total of 145 patients (54.3%) completed 5 years' treatment. The proportion of patients with two or more consecutive postbaseline measurements (≥7 days apart) of serum creatinine higher than age-adjusted upper limit of normal (ULN) and alanine aminotransferase more than five times the ULN was 4.4% (95% confidence interval [CI]: 2.1-7.9) and 4.0% (95% CI: 1.8-7.4), respectively. Median serum ferritin decreased from 1,702 ng/ml at baseline to 1,127 ng/ml at 5 years. There were no new safety signals. Safety and efficacy of deferasirox in young pediatric patients in this long-term, observational study in everyday clinical practice were consistent with the known deferasirox profile. © 2017 The Authors.

Ibrutinib, an oral inhibitor of Bruton tyrosine kinase, is approved for patients with mantle cell lymphoma (MCL) who have received one prior therapy. We report the updated safety and efficacy results from the multicenter, open-label phase 2 registration trial of ibrutinib (median 26.7-month follow-up). Patients (N = 111) received oral ibrutinib 560 mg once daily, and those with stable disease or better could enter a long-term extension study. The primary end point was overall response rate (ORR). The median patient age was 68 years (range, 40-84), with a median of 3 prior therapies (range, 1-5). The median treatment duration was 8.3 months; 46% of patients were treated for >12 months, and 22% were treated for ≥2 years. The ORR was 67% (23% complete response), with a median duration of response of 17.5 months. The 24-month progression-free survival and overall survival rates were 31% (95% confidence interval [CI], 22.3-40.4) and 47% (95% CI, 37.1-56.9), respectively. The most common adverse events (AEs) in >30% of patients included diarrhea (54%), fatigue (50%), nausea (33%), and dyspnea (32%). The most frequent grade ≥3 infections included pneumonia (8%), urinary tract infection (4%), and cellulitis (3%). Grade ≥3 bleeding events in ≥2% of patients were hematuria (2%) and subdural hematoma (2%). Common all-grade hematologic AEs were thrombocytopenia (22%), neutropenia (19%), and anemia (18%). The prevalence of infection, diarrhea, and bleeding was highest for the first 6 months of therapy and less thereafter. With longer follow-up, ibrutinib continues to demonstrate durable responses and favorable safety in relapsed/refractory MCL. The trial is registered to www.ClinicalTrials.gov as #NCT01236391. © 2015 by The American Society of Hematology.

Taliglucerase alfa is an enzyme replacement therapy approved for treatment of Gaucher disease (GD) in children and adults in several countries. This multicenter extension study assessed the efficacy and safety of taliglucerase alfa in pediatric patients with GD who were treatment-naïve (n=10) or switched from imiglucerase (n=5). Patients received taliglucerase alfa 30 or 60U/kg (treatment-naïve) or the same dose as previously treated with imiglucerase every other week. In treatment-naïve patients, taliglucerase alfa 30 and 60U/kg, respectively, reduced mean spleen volume (-18.6 multiples of normal [MN] and -26.0MN), liver volume (-0.8MN and -0.9MN), and chitotriosidase activity (-72.7% and -84.4%), and increased mean Hb concentration (+2.0g/dL and +2.3g/dL) and mean platelet count (+38,200/mm 3 and +138,250/mm 3 ) from baseline through 36 total months of treatment. In patients previously treated with imiglucerase, these disease parameters remained stable through 33 total months of treatment with taliglucerase alfa. Most adverse events were mild/moderate; treatment was well tolerated. These findings extend the taliglucerase alfa safety and efficacy profile and demonstrate long-term clinical improvement in treatment-naïve children receiving taliglucerase alfa and maintenance of disease stability in children switched to taliglucerase alfa. Treatment was well-tolerated, with no new safety signals. This study is registered at www.clinicaltrials.gov as NCT01411228. Copyright © 2016 Shire Human Genetic Therapies, Inc.

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.

Long-term topical treatment is often required for atopic dermatitis (AD), a chronic inflammatory skin disease. To assess the long-term safety results from a multicenter, open-label, 48-week safety study (AD-303) of patients (N = 517) ≥2 years of age with mild to moderate AD who continued crisaborole treatment, a topical phosphodiesterase-4 inhibitor, after completing a 28-day phase 3 pivotal study (AD-301, AD-302). Global disease severity was assessed in patients every 4 weeks, and if assessed as mild or greater, a 28-day treatment period with crisaborole applied twice daily was initiated. Adverse events (AEs), including treatment-emergent AEs (TEAEs), and serious AEs were analyzed. During the pivotal studies and AD-303, 65% of patients reported ≥1 TEAE, most of which were mild (51.2%) or moderate (44.6%) and considered unrelated to treatment (93.1%). The frequency and severity of TEAEs were consistent. The most frequently reported treatment-related AEs (overall, 10.2%) were dermatitis atopic (3.1%), application-site pain (2.3%), and application-site infection (1.2%). Nine patients (1.7%) discontinued the long-term study because of TEAEs. Long-term efficacy was not analyzed. Crisaborole ointment had a low frequency of treatment-related AEs over 48 weeks of treatment of patients with AD. Copyright © 2017 American Academy of Dermatology, Inc. Published by Elsevier Inc.

To assess the long-term safety and efficacy of canakinumab in Japanese patients with cryopyrin-associated periodic syndrome (CAPS). In this open-label phase 3 study, Japanese patients aged ≥2 years with CAPS received canakinumab 2-8 mg/kg subcutaneously every 8 weeks. The duration of the core treatment phase was 24 weeks followed by 22 months extension phase. The primary objective was the proportion of patients free of clinical and serologic relapse at week 24. The study enrolled 19 Japanese patients (median age, 14 years; range, 2-48 years) with CAPS [MWS, 7 (36.8%); NOMID, 12 (63.2%)] for a median of 109 weeks. Fifteen patients (79%) achieved a complete response by day 15, 18 (94.7%) by week 24 and all by week 48. At the end of the study, 18 (95%) were free from relapse and 11 (57.9%) were assessed as having no disease activity by the PGA. Thirteen (68%) patients (MWS, 4; NOMID, 9) had their canakinumab dose increased during the trial. All patients experienced at least one adverse event (AE), the most common being infections (100%) and 5 (26.3%) reported serious AEs. No deaths were reported and the only patient who discontinued the study early withdrew consent. Regular canakinumab treatment every 8 weeks at dose levels from 2-8 mg/kg, based on the clinical need, represents a successful strategy to induce rapid and complete response while maintain long-term disease control in Japanese patients with CAPS. The safety profile of canakinumab was consistent with that observed from previous studies.

Trelagliptin is a novel once-weekly oral dipeptidyl peptidase-4 inhibitor for type 2 diabetes mellitus that was first approved in Japan. We evaluated long-term safety and efficacy of trelagliptin in Japanese patients with type 2 diabetes mellitus. This was a phase 3, multicenter, open-label study to evaluate long-term safety and efficacy of trelagliptin. Patients with type 2 diabetes mellitus inadequately controlled despite diet/exercise or treatment with one of the existing oral antidiabetic drugs along with diet/exercise received trelagliptin 100 mg orally once weekly for 52 weeks as monotherapy or combination therapies. The primary end-points were the safety variables, and the secondary end-points were glycosylated hemoglobin and fasting plasma glucose. A total of 680 patients received the following antidiabetic therapies: trelagliptin monotherapy (n = 248), combination with a sulfonylurea (n = 158), a glinide (n = 67), an α-glucosidase inhibitor (n = 65), a biguanide (n = 70), or a thiazolidinedione (n = 72). During the study, 79.8% of the patients experienced at least one adverse event for monotherapy, 87.3% for combination with a sulfonylurea, 77.6% for a glinide, 81.5% for an α-glucosidase inhibitor, 64.3% for a biguanide, and 84.7% for a thiazolidinedione, respectively. Most of the adverse events were mild or moderate. The change in glycosylated hemoglobin from baseline at the end of the treatment period was -0.74 to -0.25% for each therapy. Once-weekly oral trelagliptin provides well-tolerated long-term safety and efficacy in both monotherapy and combination therapies in Japanese patients with type 2 diabetes mellitus. © 2016 The Authors.

Literature supports short-term efficacy and safety of Sensor Augmented Insulin Pump (SAP) therapy in patients with type 1 diabetes (T1D). However, no data are available showing long-term outcomes. Our study describes the long-term outcomes of SAP therapy with low-glucose suspend feature (SAP+LGS) in hypoglycemia in a Colombian population with T1D and hypoglycemia. A cohort study was conducted with T1D patients receiving SAP+LGS therapy who initiated this therapy because of hypoglycemia at San Ignacio University Hospital diabetes center in Bogotá, Colombia. Glycated hemoglobin (A1c) was assessed at least every 6 months, severe hypoglycemia (SH) and hypoglycemia unawareness (HU) incidence yearly. Adherence to therapy was also evaluated. One hundred eleven patients were included in the analysis. Total daily insulin dose was reduced during follow-up (mean difference -0.22 U/kg; 95% confidence interval [CI] -0.18 to -0.26; P < 0.001). A1c levels were reduced from a baseline value of 8.8% ± 1.9% to 7.5% ± 1.0% at 5 months (mean difference -1.3%; 95% CI -1.09 to -1.50; P < 0.001) and 7.1% ± 0.8% (mean difference -1.7%; 95% CI -1.59 to -1.90; P < 0.001) at the end of follow-up (47 months on average). The incidence of SH and HU episodes decreased significantly since the first year, and this effect was maintained over time (P < 0.001). SAP+LGS therapy in T1D patients with hypoglycemia led to a significant and sustained decrease in A1c during long periods of follow-up, as well as a significant reduction in SH and HU. Future randomized clinical trials are desired.

Eslicarbazepine acetate (ESL) is a new antiepileptic drug (AED) licensed as adjunctive therapy in adults with partial-onset or focal seizures. To evaluate in a clinical practice setting the long-term efficacy and safety of ESL in patients with focal seizures. ESLIBASE was a retrospective study that included all patients with focal seizures who started ESL between January 2010 and July 2012 at 12 hospitals. ESL was prescribed individually according to real-life practice. Efficacy and safety were evaluated over 1 year. Switching from carbamazepine (CBZ) and oxcarbazepine (OXC) was assessed. Three hundred and twenty-seven patients were included; 78% of patients were taking ≥2 other AEDs at baseline. Most (87%) began ESL because of poor seizure control and 13% because of adverse events (AEs) with CBZ or OXC. After 1 year, 237 patients (72.4%) remained on ESL. At 3, 6 and 12 months, the responder rate was 46.3%, 57.9%, and 52.5%, and 21.0%, 28.0%, and 25.3% of patients were seizure free. The responder rate significantly increased when ESL was combined with a non-sodium channel-targeting drug (non-SC drug) (66.7%) versus an SC drug (47.7%; p<0.001). At 12 months, 40.7% of patients had ≥1 AE; AEs led to treatment discontinuation in 16.2%. Dizziness, nausea, and somnolence were the most common AEs. The tolerability profile improved in >50% of the patients who switched from CBZ or OXC to ESL because of AEs. ESL was well tolerated and effective in a real-world setting over 1 year. Side-effect profile improved when OXC and CBZ recipients were switched to ESL. Copyright © 2014 Elsevier B.V. All rights reserved.

Background: The plasma-derived, pasteurized, nanofiltered C1-inhibitor concentrate (pnfC1-INH) is approved in the United States as an intravenous (IV) on-demand treatment for hereditary angioedema (HAE) attacks, and, in Europe, as on demand and short-term prophylaxis. Objective: This analysis evaluated Berinert Patient Registry data regarding IV pnfC1-INH used as long-term prophylaxis (LTP). Methods: The international registry (2010–2014) collected prospective and retrospective usage, dosing, and safety data on individuals who used pnfC1-INH for any reason. Results: The registry included data on 47 subjects (80.9% female subjects; mean age, 44.8 years), which reflected 4082 infusions categorized as LTP and a total of 430.2 months of LTP administration. The median absolute dose of pnfC1-INH given for LTP was 1000 IU (range, 500–3000 IU), with a median time interval between infusion and a subsequent pnfC1-INH–treated attack of 72.0 hours (range, 0.0–166.4 hours). Fifteen subjects (31.9%) had no pnfC1-INH–treated HAE attacks within 7 days after pnfC1-INH infusion for LTP; 32 subjects (68.1%) experienced 246 attacks, with rates of 0.06 attacks per infusion and 0.57 attacks per month. A total of 81 adverse events were reported in 16 subjects (34.0%) (0.02 events per infusion; 0.19 events per month); only 3 adverse events were considered related to pnfC1-INH (noncardiac chest pain, postinfusion headache, deep vein thrombosis in a subject with an IV port). Conclusion: In this international registry, IV pnf-C1-INH given as LTP for HAE was safe and efficacious, with a low rate of attacks that required pnfC1-INH treatment, particularly within the first several days after LTP administration.

Long-term (up to 8 years of exposure) safety and efficacy of the antiepileptic drug lacosamide was evaluated in this open-label extension trial (SP615 [ClinicalTrials.gov identifier: NCT00552305]). Patients were enrolled following participation in a double-blind trial or one of two open-label trials of adjunctive lacosamide for partial-onset seizures. Dosage adjustments of lacosamide (100-800 mg/day) and/or concomitant antiepileptic drugs were allowed to optimize tolerability and seizure reduction. Of the 370 enrolled patients, 77%, 51%, and 39% had >1, >3, or >5 years of lacosamide exposure, respectively. Median lacosamide modal dose was 400mg/day. Common treatment-emergent adverse events (TEAEs) were dizziness (39.7%), headache (20.8%), nausea (17.3%), diplopia (17.0%), fatigue (16.5%), upper respiratory tract infection (16.5%), nasopharyngitis (16.2%), and contusion (15.4%). Dizziness (2.2%) was the only TEAE that led to discontinuation in >2% of patients. Ranges for median percent reductions in seizure frequency were 47-65%, and those for ≥ 50% responder rates were 49-63% for 1-, 3-, and 5-year completer cohorts. Exposure to lacosamide for up to 8 years was generally well tolerated, with a safety profile similar to previous double-blind trials, and efficacy was maintained. Copyright © 2014 Elsevier Inc.

The three 5-ASA products MMX, Salofalk®, and Pentasa® employed in those studies so far have not shown differences in efficacy between OD and conventional dosing. No differences regarding safety outcomes have been detected between OD and conventional dosing, including incidence of adverse events, serious adverse events, or withdrawal from treatment due to an adverse event. Although the majority of patients prefer OD dosing to conventional dosing, it was not possible to detect differences in adherence between OD and multiple dose regimens in the clinical trial setting. Well-designed and controlled large-scale community-based studies are necessary to further investigate and prove the point of improved long-term adherence and treatment efficacy in OD dosing.

Efficacy and safety of novel antipsychotic (AP) drugs (amisulpride, olanzapine, quetiapine, ziprasidone and zotepine) have been reviewed. Data on their antipsychotic efficacy and side effects profile have been evaluated only on the basis of controlled trials so far published. Overall, all these drugs have shown an antipsychotic efficacy on positive symptoms of schizophrenia similar to that of the conventional AP drugs. On negative symptoms, all novel AP drugs, except quetiapine and ziprasidone, demonstrated a better efficacy than haloperidol. Long-term efficacy of these AP drugs in the maintenance treatment of schizophrenia needs to be explored by further, better-designed, epidemiological studies. The safety profile shows that the novel AP drugs are generally well-tolerated and induce significantly less acute extrapyramidal side effects in comparison with haloperidol. Some methodological flaws in the experimental design of the clinical trials analysed are discussed. Although these novel AP drugs have potential clinical advantages, a number of relevant questions still remain to be addressed, in order to establish the impact of these drugs in the overall treatment of schizophrenia.

This post-marketing surveillance examined the safety and efficacy of long-term teneligliptin therapy in Japanese patients. We report interim results (cut-off date: 28 June 2017) of a 3-year PMS undertaken in subjects with type 2 diabetes mellitus (T2DM). Survey items included demographics, treatments, adverse drug reactions (ADRs), and laboratory variables. A subgroup analysis was also performed across three age groups (<65 years; 65 to <75 years; ≥75 years). Main outcome measures were incidence of ADRs, laboratory variables, and change in glycated hemoglobin (HbA1c) from baseline over time. Of 11,677 patients registered, data from 10,532 patients (6,338 males/4,194 females) were analyzed for the safety analysis set; the median administration period was 731 days. Overall, ADRs and serious ADRs were reported in 364 (3.46%) and 91 patients (0.86%), respectively. The most common ADRs were all hypoglycemia (0.32%), constipation (0.27%), and hepatic function abnormal (0.24%). No change in mean body weight occurred, and a reduction in mean HbA1c was observed until 2 years. The safety and efficacy profiles did not differ markedly among the three age groups. These interim results show that teneligliptin was well tolerated and improved hyperglycemia in Japanese patients with T2DM in clinical practice.

This subgroup analysis of STELLA-LONG TERM interim data explored the long-term safety and efficacy of ipragliflozin in non-elderly vs. elderly Japanese type 2 diabetes mellitus (T2DM) patients. STELLA-LONG TERM is an ongoing 3-year prospective surveillance study of Japanese T2DM patients receiving ipragliflozin 50 mg once daily. In this subgroup analysis, patient characteristics, laboratory variables, and adverse drug reactions (ADRs) were compared between non-elderly (<65 years) and elderly (≥65 years) patients. Non-elderly patients had significantly higher body mass index and low-density lipoprotein cholesterol than elderly patients (P < 0.001). The proportion of patients with hemoglobin A1c (HbA1c) <8.0% was significantly higher among elderly patients (P < 0.001). HbA1c, fasting plasma glucose, and body weight significantly decreased from baseline to 3 and 12 months in both groups (all P < 0.05 vs. baseline). The ADR incidence was 10.83% vs. 10.42% in non-elderly and elderly patients. The incidence of skin complications was 0.98% vs. 1.65% and that of renal disorder was 0.47% vs. 0.95% in non-elderly and elderly patients (both P = 0.003). Ipragliflozin was effective in non-elderly and elderly Japanese T2DM patients in a real-world clinical setting. The incidence of renal disorder and skin complications was significantly higher in elderly vs. non-elderly patients.

Safety and Efficacy Endpoints for Mesenchymal Stromal Cell Therapy in Renal Transplant Recipients.

Despite excellent short-term graft survival after renal transplantation, the long-term graft outcome remains compromised. It has become evident that a combination of sustained alloreactivity and calcineurin-inhibitor- (CNI-) related nephrotoxicity results in fibrosis and consequently dysfunction of the graft. New immunosuppressive regimens that can minimize or eliminate side effects, while maintaining efficacy, are required to improve long-term graft survival. In this perspective mesenchymal stromal cells (MSCs) are an interesting candidate, since MSCs have immunosuppressive and regenerative properties. The first clinical trials with MSCs in renal transplantation showed safety and feasibility and displayed promising results. Recently, the first phase II studies have been started. One of the most difficult and challenging aspects in those early phase trials is to define accurate endpoints that can measure safety and efficacy of MSC treatment. Since both graft losses and acute rejection rates declined, alternative surrogate markers such as renal function, histological findings, and immunological markers are used to measure efficacy and to provide mechanistic insight. In this review, we will discuss the current status of MSCs in renal transplantation with a focus on the endpoints used in the different experimental and clinical studies.

To evaluate the long-term safety and efficacy of vibegron 50 mg and 100 mg, a novel β 3 -adrenoreceptor agonist, in Japanese patients with overactive bladder. This was a 1-year, multicenter, open-label, non-controlled study. After a 1-week observation phase, patients were treated with vibegron for 52 weeks. When the efficacy was insufficient after an 8-week treatment with 50 mg, the dose was increased to 100 mg and maintained for an additional 44 weeks. Among a total of 169 patients receiving one or more doses of vibegron, 118 (69.8%) received vibegron 50 mg for 52 weeks, and the dose was increased to 100 mg in 51 (30.2%) patients. The incidence of drug-related adverse events was 18.1% (21/116) in the vibegron 50 mg group and 11.8% (6/51) in the vibegron 100 mg group. Most frequent drug-related adverse events were dry mouth (3.0%), residual urine volume increased (3.0%), constipation (2.4%) and cystitis (1.8%). Statistically significant changes in overactive bladder symptom variables (daily means of micturitions, urgency episodes, urgency incontinence episodes, incontinence episodes and night-time frequency) from baseline were observed at week 4 and maintained until week 52. The condition of patients who did not respond well to vibegron 50 mg was much improved by increasing the dose to 100 mg. Vibegron improved the quality of life, and the proportion of patients' satisfaction after the treatment with vibegron was high. Long-term (52-week) treatment with vibegron is safe, well-tolerated and effective in patients with overactive bladder. © 2018 The Authors.

Aim: We investigated the safety and efficacy of a long-term combination therapy with fenofibrate and ezetimibe in Japanese patients with combined hyperlipidemia, in comparison with fenofibrate or ezetimibe alone. Methods: The study was a three-arm parallel-group, open-label randomized trial. Eligible patients were assigned to a combination therapy with fenofibrate (200 mg/day in capsule form or 160 mg/day in tablet form) and ezetimibe (10 mg/day), the fenofibrate monotherapy, or the ezetimibe monotherapy, which lasted for 52 weeks. The changes in serum low-density lipoprotein (LDL) cholesterol and triglycerides were the primary outcomes. Results: A total of 236 patients were assigned to one of the three treatments, and the number of patients included in the final analysis was 107 in the combination therapy, 52 in the fenofibrate monotherapy, and 51 in the ezetimibe monotherapy. Mean ± SD changes in LDL cholesterol were −24.2% ± 14.7% with combination therapy, −16.0% ± 16.0% with fenofibrate alone, and −17.4% ± 10.1% with ezetimibe alone. The combination therapy resulted in a significantly greater reduction in LDL cholesterol as compared with each monotherapy (p < 0.01 for each). The corresponding values for triglycerides were −40.0% ± 29.5%, −40.1% ± 28.7%, and −3.4% ± 32.6%, respectively. Fenofibrate use was associated with some changes in laboratory measurements, but there was no differential adverse effect between the combination therapy and fenofibrate monotherapy. Conclusion: The combination therapy with fenofibrate and ezetimibe substantially reduces concentrations of LDL cholesterol and triglycerides and is safe in a long-term treatment in Japanese patients with combined hyperlipidemia.

The relationship between tumour necrosis factor-alpha (TNF-α) and drug survival had not been studied in juvenile idiopathic arthritis (JIA), and there were no laboratory tests to predict the long-term efficacy of biological drugs for JIA. We studied whether serum levels of TNF-α, free or bound to etanercept, could predict long-term efficacy of etanercept in children with JIA. We included 41 biologic-naïve patients with JIA who started treatment with etanercept at Skåne University Hospital between 1999 and 2010. Serum taken at the start of treatment and at the six-week follow-up were analysed for TNF-α and the long-term efficacy of etanercept was assessed using the drug survival time. Levels of TNF-α increased significantly at the six-week follow-up, and this was almost exclusively comprised of TNF-α in complex with etanercept. The increase in TNF-α showed a dose-dependent correlation to long-term drug survival (p < 0.01). Increasing levels of circulating TNF-α at treatment initiation predicted long-term efficacy of etanercept in children with JIA, which may have been due to different pathophysiological mechanisms of inflammation. Our result may provide a helpful clinical tool, as high levels of circulating TNF-α/etanercept complexes could be used as a marker for the long-term efficacy of etanercept. ©2015 The Authors.

To evaluate the safety of saxagliptin ± metformin over 4 years in patients with Type 2 diabetes mellitus. Drug-naive (n = 401; study 11) or metformin-treated (n = 743; study 14) adults with HbA(1c) of 53-86 mmol/mol (7.0-10%) were enrolled in two randomized, placebo-controlled, double-blind trials of saxagliptin 2.5, 5 or 10 mg/day. Patients rescued during or completing 24 weeks of treatment could continue in a 42-month long-term blinded phase, for which the primary goal was assessment of safety and tolerability. Between-group efficacy was not evaluated in the long-term phase of study 11. Time to rescue or discontinuation because of inadequate glycaemic control, change from baseline in HbA(1c) and percentages of patients achieving HbA(1c) < 53 mmol/mol (< 7.0%) were assessed in study 14. No new safety findings were noted during the long-term phase. Most adverse events were mild or moderate, with slightly greater frequency of upper respiratory infections with saxagliptin. Hypoglycaemic event rates were similar with saxagliptin and placebo. In study 14, time to rescue or discontinuation because of inadequate glycaemic control was longer with saxagliptin plus metformin than for placebo plus metformin. From baseline to week 154, HbA(1c) decreased with saxagliptin but increased with placebo. Saxagliptin monotherapy or add-on to metformin is generally safe and well tolerated, with no increased risk of hypoglycaemia, for up to 4 years. © 2013 The Authors.

To assess long-term safety and efficacy of stiripentol as an antiepileptic medication for people with Dravet syndrome. A prospective, observational open-label study (2003-2015) of the efficacy and long-term safety of stiripentol in patients with Dravet syndrome and ongoing seizures. Frequency of generalized tonic-clonic seizures, focal seizures, status epilepticus, and adverse events were recorded. Forty-one patients started stiripentol, with median age at enrolment 5 years 7 months (range 11mo-22y) and median duration of treatment 37 months (range 2-141mo). Twenty out of 41 patients had greater than or equal to 50% long-term reduction in frequency of generalized tonic-clonic seizures. Frequency of focal seizures was decreased by greater than or equal to 50% in 11 out of 23 patients over the long-term. Frequency of status epilepticus was decreased by 50% or more in 11 out of 26 patients. The most common adverse events were anorexia, weight loss, sedation, and behavioural changes. One patient had worsening of absence and myoclonic seizures. Another developed recurrent pancreatitis on concurrent valproate. Stiripentol improves long-term seizure frequency in approximately 50% of patients with Dravet syndrome, when used as part of unrestricted polytherapy. Long-term use appears safe. In more than 40% of patients, episodes of status epilepticus markedly decrease after stiripentol initiation. What this paper adds Frequency of status epilepticus is reduced in 40% of patients with Dravet syndrome after stiripentol initiation. Stiripentol is effective for generalized tonic-clonic and focal seizures. Stiripentol can be safely used with a range of antiepileptic drugs. © 2018 Mac Keith Press.

Short-term trials have demonstrated the efficacy and safety of combination therapy using antimuscarinics and α-blockers in men with lower urinary tract symptoms (LUTS). The Study of Solifenacin Succinate and Tamsulosin Hydrochloride OCAS (oral controlled absorption system) in Males with Lower Urinary Tract Symptoms (NEPTUNE) II is the first long-term study using solifenacin (Soli) and the oral controlled absorption system formulation of tamsulosin (TOCAS). To evaluate long-term (up to 52 wk) safety and efficacy of flexible dosing of two fixed-dose combinations (FDC) of Soli plus TOCAS in men with moderate to severe storage symptoms and voiding symptoms. Patients with both storage and voiding LUTS, maximum urinary flow rate of 4.0-12.0 ml/s, prostate size <75 ml, and postvoid residuals ≤ 150 ml, who completed the 12-wk, double-blind NEPTUNE study could continue in the 40-wk, open-label NEPTUNE II study. FDC of Soli 6 mg plus TOCAS 0.4 mg, or Soli 9 mg plus TOCAS 0.4mg; patients could switch between doses in NEPTUNE II. Safety and efficacy data from NEPTUNE and NEPTUNE II were combined to cover a 52-wk period. Primary efficacy end points were total International Prostate Symptom Score (IPSS) and total urgency and frequency score (TUFS); secondary end points included IPSS storage and voiding subscores, micturition diary variables, and quality of life parameters. In all, 1066 men completed NEPTUNE and received one dose or more of study medication in NEPTUNE II. Treatment-emergent adverse events were reported in 499 (46.8%) patients who participated in NEPTUNE II; most were mild or moderate. Urinary retention occurred in 13 of 1208 (1.1%) patients receiving one or more FDCs in NEPTUNE and/or NEPTUNE II; 8 (0.7%) required catheterisation (acute urinary retention [AUR]). Reductions in total IPSS and TUFS during NEPTUNE were maintained for up to 52 wk of FDC treatment, with mean reductions of 9.0 (standard deviation [SD]: 5.7) and 10.1 (SD: 9.2), respectively, from

Previous analyses from a randomized trial in women aged 24-45 have shown the quadrivalent HPV vaccine to be efficacious in the prevention of infection, cervical intraepithelial neoplasia (CIN) and external genital lesions (EGL) related to HPV 6/11/16/18 through 4 years. In this report we present long term follow-up data on the efficacy, safety and immunogenicity of the quadrivalent HPV vaccine in adult women. Follow-up data are from a study being conducted in 5 sites in Colombia designed to evaluate the long-term immunogenicity, effectiveness, and safety of the qHPV vaccine in women who were vaccinated at 24 to 45 years of age (in the original vaccine group during the base study [n = 684]) or 29 to 50 years of age (in the original placebo group during the base study [n = 651]). This analysis summarizes data collected as of the year 6 post-vaccination visit relative to day 1 of the base study (median follow-up of 6.26 years) from both the original base study and the Colombian follow-up. There were no cases of HPV 6/11/16/18-related CIN or EGL during the extended follow-up phase in the per-protocol population. Immunogenicity persists against vaccine-related HPV types, and no evidence of HPV type replacement has been observed. No new serious adverse experiences have been reported. Vaccination with qHPV vaccine provides generally safe and effective protection from HPV 6-, 11-, 16-, and 18-related genital warts and cervical dysplasia through 6 years following administration to 24-45 year-old women.

Attention-deficit/hyperactivity disorder (ADHD) is a chronic psychiatric disorder characterized by hyperactivity and/or inattention and is often associated with a substantial impact on psychosocial functioning. Methylphenidate (MPH), a central nervous system stimulant, is commonly used for pharmacological treatment of adults and children with ADHD. Current practice guidelines recommend optimizing MPH dosage to individual patient needs; however, the clinical benefits of individual dose optimization compared with fixed-dose regimens remain unclear. Here we review the available literature on MPH dose optimization from clinical trials and real-world experience on ADHD management. In addition, we report safety and efficacy data from the largest MPH modified-release long-acting Phase III clinical trial conducted to examine benefits of dose optimization in adults with ADHD. Overall, MPH is an effective ADHD treatment with a good safety profile; data suggest that dose optimization may enhance the safety and efficacy of treatment. Further research is required to establish the extent to which short-term clinical benefits of MPH dose optimization translate into improved long-term outcomes for patients with ADHD. PMID:28740389

Primary bladder neck obstruction (PBNO) is a nonneurogenic voiding disorder and frequently overlooked in young men. Prior studies have reported the efficacy of α-blockers only in the short-term for male patients with PBNO. We hereby report our long-term results using α1-blocker therapy in young men with PBNO. Between January 2005 and December 2009, PBNO was diagnosed in 30 young men (mean age 27.3 years, range 18-35) at our institution. Doxazosin 4 mg once daily was administered for at least 12 months. Safety and tolerability were assessed, and efficacy was evaluated from International Prostate Symptom Score (I-PSS), Quality of Life (QOL), uroflowmetry, and post-void residual following 3- and 12-month treatment. Successful treatment was defined as at least 3 ml per second increase in the maximum flow rate and more than a 40% decrease in I-PSS. In all 30 patients, Mean symptom duration was 26.4 (3-65) months. The most common symptoms were hesitancy (93.3%), weak stream (76.7%), and frequency (66.7%). A total of 24 patients (80%, 24/30) successfully completed the 12 month of treatment. The medication period was 15.2 months, and follow-up duration was 16.3 months. Doxazosin was safe and well tolerated. The efficacy of doxazosin was maintained over the 12-month treatment period. Relative to baseline, there were reductions in the number of mean I-PSS (from 17.7 ± 4.2 to 10.4 ± 4.8), mean QOL (from 4.2 ± 1.1 to 2.4 ± 1.3), and mean post-void residual urine (from 79.3 ± 33.4 to 47.1 ± 21.3), and an increase in mean maximum flow rate (from 11.4 ± 2.9 to 15.1 ± 3.2 ml) after 12-month treatment. Treatment was successful in 16 patients (66.7%, 16/24) according to the improvement in both symptoms and maximum urine flow. α1-blocker therapy displayed a favorable safety, tolerability, and efficacy profile during 12-month treatment in young male patients with PBNO.

To obtain long-term safety data for pirfenidone in patients with IPF in RECAP. Of the 1,334 patients who participated in the phase 3 trials, 1,058 entered RECAP. The final analysis from enrollment (September 2008) to June 2015 is presented. Mean (SD) and median (range) pirfenidone exposures in RECAP were 122 (98) weeks and 88 (>0 to 349) weeks, respectively, with a mean daily dose of 2,091.1 mg. Cumulative total exposure was 2,482 patient exposure years (PEY). The treatment-emergent adverse event (TEAE) rate was 701.9 per 100 PEY. The serious TEAE rate was 53.5 per 100 PEY, with the most common serious TEAE being IPF (11.1 per 100 PEY). Of the 231 deaths (9.3 per 100 PEY), the most common cause was IPF (5.4 per 100 PEY). The treatment discontinuation rate due to a TEAE was 17.9 per 100 PEY; discontinuations were due to IPF (7.2 per 100 PEY), pneumonia, respiratory failure, acute respiratory failure, rash (0.5 per 100 PEY each), and nausea (0.4 per 100 PEY). For patients from CAPACITY 004/006 who entered RECAP, the mean change in percent predicted forced vital capacity from RECAP baseline at 180 weeks was -9.6%. Median on-treatment survival from the first pirfenidone dose in RECAP was 77.2 months. RECAP provides long-term follow-up and safety data for pirfenidone that were consistent with the known profile, with no new safety signals observed. © 2017 The Author(s) Published by S.

To report the long-term efficacy of custom polymethyl methacrylate implants using high-resolution computed tomographic modeling in the reconstruction of complex orbitofacial defects secondary to trauma. Nine patients with complex orbitofacial bone defects after trauma were evaluated for this retrospective, nonrandomized, noncomparative study. All the patients underwent reconstruction using custom, heat-cured polymethyl methacrylate implants. Patients were followed up postoperatively and evaluated for complications. Nine consecutive patients (5 men and 4 women) aged 28 to 63 years who underwent surgical reconstruction using prefabricated, heat-cured polymethyl methacrylate implants were included in the study. The interval between injury and presentation ranged from 1 month to 40 years. There were no significant complications, including infection, extrusion, or displacement of the implant. In all of the patients, wound healing was uneventful, with antibiotic drugs administered perioperatively. Mean follow-up was 4.3 years from the first visit (range, 6 months to 10 years). Computed tomographic biomodeled, prefabricated, heat-cured polymethyl methacrylate implants are well tolerated in the long term. Their advantages include customized design, long-term biocompatibility, and excellent aesthetic results.

Patients with essential hypertension who are receiving treatment with an angiotensin II receptor blocker and a calcium channel blocker often develop inadequate blood pressure (BP) control and require the addition of a diuretic. This study aimed to evaluate the long-term safety and efficacy of a triple combination therapy with 20 mg azilsartan (AZL), 5 mg amlodipine (AML) and 12.5 mg hydrochlorothiazide (HCTZ). The phase III, open-label, multicenter study (NCT02277691) comprised a 4-week run-in period and 52-week treatment period. Patients with inadequate BP control despite AZL/AML therapy (n = 341) received 4 weeks' treatment with AZL/AML (combination tablet) + HCTZ (tablet) and 4 weeks' treatment with AZL/AML/HCTZ (combination tablet) in a crossover manner, followed by AZL/AML/HCTZ (combination tablet) from Week 8 of the treatment period up to Week 52. The primary and secondary endpoints were long-term safety and BP (office and home), respectively. Most adverse events (AEs) were mild or moderate in intensity, and no deaths or treatment-related serious AEs were reported. The triple therapy provided consistent BP-lowering effects in both office and home measurements. The triple combination therapy with AZL/AML/HCTZ was well tolerated and effective for 52 weeks in Japanese patients with essential hypertension.

BACKGROUND In patients with severe hemophilia B, gene therapy that is mediated by a novel self-complementary adeno-associated virus serotype 8 (AAV8) vector has been shown to raise factor IX levels for periods of up to 16 months. We wanted to determine the durability of transgene expression, the vector dose–response relationship, and the level of persistent or late toxicity. METHODS We evaluated the stability of transgene expression and long-term safety in 10 patients with severe hemophilia B: 6 patients who had been enrolled in an initial phase 1 dose-escalation trial, with 2 patients each receiving a low, intermediate, or high dose, and 4 additional patients who received the high dose (2×1012 vector genomes per kilogram of body weight). The patients subsequently underwent extensive clinical and laboratory monitoring. RESULTS A single intravenous infusion of vector in all 10 patients with severe hemophilia B resulted in a dose-dependent increase in circulating factor IX to a level that was 1 to 6% of the normal value over a median period of 3.2 years, with observation ongoing. In the high-dose group, a consistent increase in the factor IX level to a mean (±SD) of 5.1±1.7% was observed in all 6 patients, which resulted in a reduction of more than 90% in both bleeding episodes and the use of prophylactic factor IX concentrate. A transient increase in the mean alanine aminotransferase level to 86 IU per liter (range, 36 to 202) occurred between week 7 and week 10 in 4 of the 6 patients in the high-dose group but resolved over a median of 5 days (range, 2 to 35) after prednisolone treatment. CONCLUSIONS In 10 patients with severe hemophilia B, the infusion of a single dose of AAV8 vector resulted in long-term therapeutic factor IX expression associated with clinical improvement. With a follow-up period of up to 3 years, no late toxic effects from the therapy were reported. (Funded by the National Heart, Lung, and Blood Institute and others; Clinical

Non-infectious uveitis represents one of the most common causes of blindness, even at pediatric age; in particular, idiopathic chronic uveitis can pose significant difficulties during treatment, due to a partial response to TNF-α antagonists. To date, very few case series exist describing the treatment of idiopathic uveitis not adequately controlled by TNF-α antagonists. The aim of our study is to describe the role of abatacept in achieving remission in patients with idiopathic uveitis previously treated with TNF-α antagonists, and to assess how long abatacept efficacy is maintained during follow-up. The treatment's safety profile and tolerability were also specifically investigated. Three patients affected with chronic idiopathic uveitis, who have been treated with abatacept due to loss of efficacy of TNF-α antagonists, were reviewed. Details of the demographic and clinical characteristics were recorded, and a summary of the medical history was obtained. Patients were regularly reviewed in the ophthalmology and rheumatology clinics. Assessment of their ocular condition was characterized according to the Standardization of Uveitis Nomenclature (SUN) group. In our patients, abatacept was able to induce remission and to discontinue systemic corticosteroids after a mean of 30 weeks; the drug maintained its efficacy through a long follow-up period (42, 33, and 18 months respectively), with an excellent safety profile. Our small case series seems to suggest abatacept to be a promising therapy in children affected with chronic idiopathic uveitis not adequately controlled by TNF-α antagonists.

Background Increasing evidence suggests that patient safety is a serious concern for older patients with long-term conditions. Despite this, there is a lack of research on safety incidents encountered by this patient group. In this study, we sought to examine patient reports of safety incidents and factors associated with reports of safety incidents in older patients with long-term conditions. Methods The baseline cross-sectional data from a longitudinal cohort study were analysed. Older patients (n=3378 aged 65 years and over) with a long-term condition registered in general practices were included in the study. The main outcome was patient-reported safety incidents including availability and appropriateness of medical tests and prescription of wrong types or doses of medication. Binary univariate and multivariate logistic regression analyses were undertaken to examine factors associated with patient-reported safety incidents. Results Safety incidents were reported by 11% of the patients. Four factors were significantly associated with patient-reported safety incidents in multivariate analyses. The experience of multiple long-term conditions (OR=1.09, 95% CI 1.05 to 1.13), a probable diagnosis of depression (OR=1.36, 95% CI 1.06 to 1.74) and greater relational continuity of care (OR=1.28, 95% CI 1.08 to 1.52) were associated with increased odds for patient-reported safety incidents. Perceived greater support and involvement in self-management was associated with lower odds for patient-reported safety incidents (OR=0.95, 95% CI 0.93 to 0.97). Conclusions We found that older patients with multimorbidity and depression are more likely to report experiences of patient safety incidents. Improving perceived support and involvement of patients in their care may help prevent patient-reported safety incidents. PMID:28559454

After trauma or surgery, researchers have suggested that medium-chain triglycerides have metabolic advantages, although they are toxic in large doses. To try to reduce this potential toxicity, structured lipids, which provide a higher oxidation rate, faster clearance from blood, improved nitrogen balance, and less accumulation in the reticuloendothelial system, could be used. Therefore, we evaluated, through a blind randomized study, the safety, tolerance, and efficacy of structured triglycerides, compared with long-chain triglycerides (LCT), in patients undergoing colorectal surgery. Nineteen patients were randomized to receive long-chain or structured triglycerides as a lipid source. They received the same amount of calories (27.2/kg/d), glucose (4 g/kg/d), protein (0.2 g/kg/d), and lipids (11.2 kcal/kg/d). Patients were evaluated during and after the treatment for clinical and laboratory variables, daily and cumulative nitrogen balance, urinary excretion of 3-methyl-histidine, and urinary 3-methylhistidine/creatinine ratio. No adverse effect that required the interruption of the treatment was observed. Triglyceride levels and clinical and laboratory variables were similar in the two groups. A predominantly positive nitrogen balance was observed from day 2 until day 5 in the LCT group and from day 1 until day 4 in the structured triglycerides group. The cumulative nitrogen balance (in grams) for days 1 to 3 was 9.7+/-5.2 in the experimental group and 4.4+/-11.8 in the control group (p = .2). For days 1 to 5 it was 10.7+/-10.5 and 6.5+/-17.9 (p = .05), respectively. The excretion of 3-methylhistidine was higher in the control group but decreased in the following days and was similar to the experimental group on day 5. This study represents the first report in which structured triglycerides are administered in postoperative patients to evaluate safety, tolerance, and efficacy. It suggests that Fe73403 is safe, well tolerated, and efficacious in terms of nitrogen

Tapentadol extended release (ER) has demonstrated efficacy and safety for the management of moderate to severe, chronic pain in adults. This study evaluated the long-term safety and tolerability of tapentadol ER in patients with chronic osteoarthritis or low back pain. Patients were enrolled in this 1-year, open-label extension study after completing one of two 15-week, placebo-controlled studies of tapentadol ER and oxycodone controlled release (CR) for osteoarthritis knee pain (NCT00421928) or low back pain (NCT00449176), a 7-week crossover study between tapentadol immediate release and tapentadol ER for low back pain (NCT00594516), or a 1-year safety study of tapentadol ER and oxycodone CR for osteoarthritis or low back pain (NCT00361504). After titrating the drug to an optimal dose, patients received tapentadol ER (100-250 mg BID) for up to 1 year (after finishing treatment in the preceding studies); patients who were previously treated with tapentadol ER in the 1-year safety study received tapentadol ER continuously for up to 2 years in total. Of the 1,154 patients in the safety population, 82.7% were aged >65 years and 57.9% were female; 50.1% had mild baseline pain intensity. Mean (SD) pain intensity scores (11-point numerical rating scale) were 3.9 (2.38) at baseline (end of preceding study) and 3.7 (2.42) at end point, indicating that pain relief was maintained during the extension study. Improvements in measures of quality of life (eg, EuroQol-5 Dimension and the 36-item Short Form Health Survey [SF-36]) health status questionnaires) achieved during the preceding studies were maintained during the open-label extension study. Tapentadol ER was associated with a safety and tolerability profile comparable to that observed in the preceding studies. The most common treatment-emergent adverse events (incidence ≥10%; n = 1154) were headache (13.1%), nausea (11.8%), and constipation (11.1%). Similar efficacy and tolerability results were shown for patients who

The 24-week safety and efficacy of lumacaftor/ivacaftor combination therapy was shown in two randomised controlled trials (RCTs)-TRAFFIC and TRANSPORT-in patients with cystic fibrosis who were aged 12 years or older and homozygous for the F508del-CFTR mutation. We aimed to assess the long-term safety and efficacy of extended lumacaftor/ivacaftor therapy in this group of patients in PROGRESS, the long-term extension of TRAFFIC and TRANSPORT. PROGRESS was a phase 3, parallel-group, multicentre, 96-week study of patients who completed TRAFFIC or TRANSPORT in 191 sites in 15 countries. Patients were eligible if they were at least 12 years old with cystic fibrosis and homozygous for the F508del-CFTR mutation. Exclusion criteria included any comorbidity or laboratory abnormality that, in the opinion of the investigator, might confound the results of the study or pose an additional risk in administering the study drug to the participant, history of drug intolerance, and history of poor compliance with the study drug. Patients who previously received active treatment in TRANSPORT or TRAFFIC remained on the same dose in PROGRESS. Patients who had received placebo in TRANSPORT or TRAFFIC were randomly assigned (1:1) to receive lumacaftor (400 mg every 12 h)/ivacaftor (250 mg every 12 h) or lumacaftor (600 mg once daily)/ivacaftor (250 mg every 12 h). The primary outcome was to assess the long-term safety of combined therapy. The estimated annual rate of decline in percent predicted FEV 1 (ppFEV 1 ) in treated patients was compared with that of a matched registry cohort. Efficacy analyses were based on modified intention-to-treat, such that data were included for all patients who were randomly assigned and received at least one dose of study drug. This study is registered with ClinicalTrials.gov, number NCT01931839. Between Oct 24, 2013, and April 7, 2016, 1030 patients from the TRANSPORT and TRAFFIC studies enrolled in PROGRESS, and 1029 received at least one dose of study

New treatment options for chronic constipation: Mechanisms, efficacy and safety

The present review has several objectives, the first of which is to review the pharmacology and selectivity of serotonergic agents to contrast the older serotonergic agents (which were withdrawn because of cardiac or vascular adverse effects) with the newer generation serotonin receptor subtype 4 agonists. Second, the chloride ion secretagogues that act through the guanylate cyclase C receptor are appraised and their pharmacology is compared with the approved medication, lubiprostone. Third, the efficacy and safety of the application of bile acid modulation to treat constipation are addressed. The long-term studies of surgically induced excess bile acid delivery to the colon are reviewed to ascertain the safety of this therapeutic approach. Finally, the new drugs for opiate-induced constipation are introduced. Assuming these drugs are approved, practitioners will have a choice; however, patient responsiveness will be based on trial and error. Nevertheless, the spectrum of mechanisms and demonstrated efficacy and safety augur well for satisfactory treatment outcomes. PMID:22114755

Team safety and team innovation are underexplored in the context of long-term care. Understanding the issues requires attention to how teams cope with error. Team managers could have an important role in developing a team's error orientation and managing team membership instabilities. The aim of this study was to examine the impact of team member stability, team coaching, and a team's error orientation on team safety and innovation. A cross-sectional survey method was employed within 2 long-term care organizations. Team members and team managers received a survey that measured safety and innovation. Team members assessed member stability, team coaching, and team error orientation (i.e., problem-solving and blaming approach). The final sample included 933 respondents from 152 teams. Stable teams and teams with managers who take on the role of coach are more likely to adopt a problem-solving approach and less likely to adopt a blaming approach toward errors. Both error orientations are related to team member ratings of safety and innovation, but only the blaming approach is (negatively) related to manager ratings of innovation. Differences between members' and managers' ratings of safety are greater in teams with relatively high scores for the blaming approach and relatively low scores for the problem-solving approach. Team coaching was found to be positively related to innovation, especially in unstable teams. Long-term care organizations that wish to enhance team safety and innovation should encourage a problem-solving approach and discourage a blaming approach. Team managers can play a crucial role in this by coaching team members to see errors as sources of learning and improvement and ensuring that individuals will not be blamed for errors.

The long-term safety, tolerability, and efficacy of high-dose 13.3 mg/24 h rivastigmine patch in severe Alzheimer disease was evaluated in a 24-week, open-label extension to the double-blind ACTION study. Safety and tolerability, and efficacy on the Alzheimer's Disease Cooperative Study-Activities of Daily Living scale-Severe Impairment Version (ADCS-ADL-SIV), Severe Impairment Battery (SIB), and ADCS-Clinical Global Impression of Change (ADCS-CGIC) were assessed. Overall, 197 patients continued on 13.3 mg/24 h patch; 199 uptitrated from 4.6 mg/24 h to 13.3 mg/24 h patch. The incidence of adverse events (AEs), serious AEs and discontinuations due to AEs was similar in patients who continued on, and patients who uptitrated to, 13.3 mg/24 h patch (AEs: 57.9% and 59.8%; serious AEs: 16.2% and 16.1%; discontinuations: 11.2% and 12.1%, respectively). Larger mean changes from double-blind baseline were observed in patients uptitrated on the ADCS-ADL-SIV (-4.6; SD=8.7) and SIB (-7.0; SD=16.6), than those who continued on 13.3 mg/24 h patch (-3.9; SD=8.0 and -4.7; SD=16.8, respectively). ADCS-CGIC scores were comparable. There were no clinically relevant between-group differences in safety and tolerability. Greater decline was observed in patients with delayed uptitration to high-dose 13.3 mg/24 h patch than patients who continued on high-dose patch.

This case study aimed to understand safety culture in a high-risk secured unit for cognitively impaired residents in a long-term care (LTC) facility. Specific objectives included the following: diagnosing the present level of safety culture maturity using the Patient Safety Culture Improvement Tool (PSCIT), examining the barriers to a positive safety culture, and identifying actions for improvement. A mixed methods design was used within a secured unit for cognitively impaired residents in a Canadian nonprofit LTC facility. Semistructured interviews, a focus group, and the Modified Stanford Patient Safety Culture Survey Instrument were used to explore this topic. Data were synthesized to situate safety maturity of the unit within the PSCIT adapted for LTC. Results indicated a reactive culture, where safety systems were piecemeal and developed only in response to adverse events and/or regulatory requirements. A punitive regulatory environment, inadequate resources, heavy workloads, poor interdisciplinary collaboration, and resident safety training capacity were major barriers to improving safety. This study highlights the importance of understanding a unit's safety culture and identifies the PSCIT as a useful framework for planning future improvements to safety culture maturity. Incorporating mixed methods in the study of health care safety culture provided a good model that can be recommended for future use in research and LTC practice.

Obesity is an increasingly common condition with serious associated morbidity and decreased life expectancy. Laparoscopic adjustable gastric banding (LAGB) has demonstrated its safety and efficacy as a surgical therapy for morbid obesity over the short term. The current study sought to determine the long-term safety and efficacy of a low-pressure LAGB. Between August 1996 and July 2007, 1,000 consecutive patients underwent LAGB implantation with the Swedish Adjustable Gastric Band (SAGB). This series was retrospectively reviewed with regard to weight loss and morbidity. Patients served as their own controls. Preoperatively, there were 808 women (81.0%) and 192 men (19.0%) with a mean age of 46 +/- 11 years (range 13-81 yrs) and mean body mass index (BMI) of 42.0 +/- 7.0 kg/m2 (range 27-82 kg/m2). At 1-, 3-, 6-, and 8-year follow-up, mean percent excess weight loss was 41% (n = 600), 56% (n = 367), 51% (n = 114), and 52% (n = 43), respectively. At the same time points, BMI decreased, from 42.0 to 31.0, 32.5, and 30.5 kg/m2, respectively. Complications occurred in 197 patients. There were 2 operative complications (i.e., stomach perforation and vascular injury) and 25 conversions (2.4%) to open surgery. Major and minor wound infection in the perioperative period occurred in 47 (4.7%) and 43 (4.3%) patients, respectively. There was 1 death from a myocardial infarct 1 week after surgery. Long term, there were 30 (3.0%) band slippages, 31 (3.1%) erosions, 67 (6.7%) port problems, and 12 (1.2%) incisional hernias. LAGB with the SAGB is effective in achieving a mean sustainable weight loss of >50% at 8 years after surgery, with an acceptably low morbidity.

Safety and efficacy of non-ergot dopamine agonists for the treatment of idiopathic restless legs syndrome have been shown in short-term trials. We did a prospective open-label extension of a 6-week, double-blind randomised trial to assess the safety, tolerability, and efficacy of rotigotine transdermal patch for up to 5 years in patients with restless legs syndrome. Patients (aged 18-75 years) with moderate-to-severe idiopathic restless legs syndrome were treated with once-daily rotigotine transdermal patch in 33 centres in Austria, Germany, and Spain between July 31, 2003, and April 15, 2009. The dose was titrated in weekly increments (up to 4 weeks) from 0·5 mg/24 h to a maximum of 4 mg/24 h, and was followed by up to 5 years of maintenance at the optimum dose. Primary safety outcomes included occurrence of adverse events and dropouts. Efficacy assessments were secondary and included the International Restless Legs Syndrome study group severity rating scale (IRLS). Augmentation of symptoms was assessed by means of standard diagnostic criteria and was confirmed by an international expert panel. All patients who received at least one dose of study drug were included in assessments. This study is registered with ClinicalTrials.gov, number NCT00498186. 295 patients entered the open-label study, of whom 126 (43%) completed 5 years of follow-up. 169 (57%) patients discontinued treatment, 89 (30%) because of adverse events and 31 (11%) because of lack of efficacy. 70 patients (24%) discontinued during year 1 of maintenance. The most common adverse events were application site reactions, which occurred in 37% (106/290) of patients in year 1, 17% (38/220) of patients in year 2, 14% (27/191) of patients in year 3, and in less than 6% of patients during year 4 (8/159) and year 5 (8/147). 56 patients (19%) discontinued because of application site reactions. Mean rotigotine dose was 2·43 mg/24 h (SD 1·21) after initial titration and 3·09 mg/24 h (1·07) at the end of

This paper summarizes the literature concerning the effects of administering (1) long-chain polyunsaturated fatty acids (LCPUFA), (2) probiotics and/or (3) prebiotics to preterm infants. Clinically relevant, short- and long-term efficacy outcomes, such as those related to a reduced risk of disease, as well as outcomes related to safety, were sought. MEDLINE and the Cochrane Library literature searches performed in September 2010 were limited to randomized controlled trials, their systematic reviews or meta-analyses. LCPUFA supplementation, particularly docosahexaenoic acid (DHA), of infant formula for preterm infants has consistently demonstrated better visual development of preterm infants compared with unsupplemented formulas. There is increasing evidence to suggest that LCPUFA supplementation for preterm infants is also related to improvements in more global measures of development, without any adverse effects. It is, however, important to note that the DHA doses tested in the infant formula interventions for preterm infants have been rather conservative. Newer studies comparing dietary DHA concentrations that match in utero accumulation rates with dietary DHA concentrations typical in the milk of women consuming little fish or in supplemented infant formulas demonstrate that these higher DHA doses are related to improvements in domains of cognitive development. Although further work is needed to better understand the optimal DHA requirements of preterm infants, it is clear that a dietary source of DHA is important to support neurodevelopment. To date, the most promising application of probiotics in preterm infants is the prevention of necrotizing enterocolitis by the administration of certain probiotics. Many other benefits of administering probiotics and/or prebiotics to preterm infants are, however, largely unproven. Efficacy and safety should be established for each probiotic and/or prebiotic product. Further research should specify strain-specific outcomes

At many hospitals and long-term care organizations (such as nursing homes), executive board members have a responsibility to manage patient safety. Executive WalkRounds offer an opportunity for boards to build a trusting relationship with professionals and seem useful as a leadership tool to pick up on soft signals, which are indirect signals or early warnings that something is wrong. Because the majority of the research on WalkRounds has been performed in hospitals, it is unknown how board members of long-term care organizations develop their patient safety policy. Also, it is not clear if these board members use soft signals as a leadership tool and, if so, how this influences their patient safety policies. The objective of this study is to explore the added value and the feasibility of WalkRounds for patient safety management in long-term care. This study also aims to identify how executive board members of long-term care organizations manage patient safety and to describe the characteristics of boards. An explorative before-and-after study was conducted between April 2012 and February 2014 in 13 long-term care organizations in the Netherlands. After implementing the intervention in 6 organizations, data from 72 WalkRounds were gathered by observation and a reporting form. Before and after the intervention period, data collection included interviews, questionnaires, and studying reports of the executive boards. A mixed-method analysis is performed using descriptive statistics, t tests, and content analysis. Results are expected to be ready in mid 2014. It is a challenge to keep track of ongoing development and implementation of patient safety management tools in long-term care. By performing this study in cooperation with the participating long-term care organizations, insight into the potential added value and the feasibility of this method will increase.

Citino, Scott B; Munson, Linda

2005-09-01

A prospective clinical trial evaluating efficacy and long-term outcome of treatments for lymphoplasmacytic gastritis in cheetahs (Acinonyx jubatus) was conducted. The study evaluated efficacy of 11 different antibiotic and antiinflammatory treatment protocols in 32 cheetahs (19 male, 13 female) for reducing gastric inflammation and Helicobacter colonization and monitored the course of disease through histologic grading of gastric biopsies. All cheetahs were biopsied up to I wk before treatment and then rebiopsied within 1 mo after treatment. Most animals were reassigned to a second treatment regimen within 6 mo. Each animal received from one to three treatments during the study period. After the trial, gastric biopsies were obtained from each cheetah annually until death or transfer from the facility to assess disease progression. The trial and follow-up period spanned 10 yr. At onset of the trial, all 32 cheetahs had some degree of gastritis, and 26 cheetahs (81%) were colonized with Helicobacter. Inflammatory lesions worsened regardless of treatment or the presence of Helicobacter. No treatment had a significant effect on inflammatory changes except the lansoprazole/clarithromycin/amoxicillin treatment group, which produced a short-term decrease in inflammation when compared to controls. Prednisone had no effect on gastric inflammation. Overall, 65% of colonized cheetahs were initially cleared of histologic evidence of Helicobacter by treatment, with short-term eradication occurring in 100% of the animals treated with omeprazole/clarithromycin/amoxicillin or tetracycline/metronidazole/Pepto-Bismol for 28 days. Long-term follow-up of treated animals in this study clearly demonstrated that these treatments had little effect on life-long progression of gastritis or on Helicobacter burden in individual cheetahs, although some treatments provided short-term reduction in gastritis and Helicobacter. These results provide evidence that Helicobacter alone is not the cause

High-dose (4.0 g/day) mesalazine is typically used for induction therapy, but its efficacy as maintenance therapy remains to be determined. We conducted a multicenter retrospective study to investigate the efficacy of continuous treatment with 4.0 g/day of mesalazine. Japanese ulcerative colitis (UC) patients receiving acute induction therapy with 4.0 g/day mesalazine were enrolled and followed. Those who clinically improved or who achieved clinical remission were categorized into 2 sub-groups according to the median duration of treatment with 4.0 g/day of mesalazine. The clinical relapse frequency and the time to relapse were analyzed. We enrolled 180 patients with active UC, and then 115 patients who clinically improved or who achieved clinical remission after treatment with 4.0 g/day mesalazine were categorized into 2 sub-groups according to the median of treatment duration: a short-term treatment group (≤105 days, n=58) and a long-term treatment group (>105 days, n=57). Overall, 45 (39.1%) patients relapsed: 28 (48.3%) in the short-term treatment group and 17 (29.8%) in the long-term treatment group. This difference was statistically significant (p<0.05). The relapse-free rate in the long-term treatment group was significantly higher than that in the short-term treatment group (p<0.05). The mean time to relapse in the long-term treatment group was significantly longer than that in the short-term treatment group (425.6±243.8 days vs. 277.4±224.5 days; p<0.05). Long-term continuous treatment with high-dose mesalazine (4.0 g/day) may be more effective than short-term treatment for maintenance of remission in UC patients.

The use of dipeptidyl peptidase (DPP)-4 inhibitors in patients with type 2 diabetes treated with insulin may be beneficial. However, the long-term efficacy and safety of vildagliptin add-on therapy in these patients remains unclear. A total of 73 patients with type 2 diabetes treated with insulin were randomly assigned to receive either add-on therapy of vildagliptin (n=37) or conventional therapy without DPP-4 inhibitors (n=36) for glucose control. Hemoglobin A1c (HbA1c) levels, dose and number of insulin injections, number of hypoglycemia episodes, and liver and renal function were monitored for 2years. The baseline characteristics of subjects, including age, dose of insulin injections, or HbA1c levels, did not differ between the two groups. In the vildagliptin group, HbA1c levels significantly decreased and the significance of HbA1c reduction was maintained for 24months (from 8.0±1.2% to 7.4±1.0%, p<0.05, at the end of observational period). In addition, the dose and number of insulin injections significantly reduced (-5.6units, p<0.01, and -0.9 times, p<0.001). However, these parameters were unchanged in the control group. The number of patients who experienced three or more episodes of hypoglycemia per year was significantly lower in the vildagliptin group (n=4) than in the control group (n=11) (odds ratio, 0.28; 95% confidence interval, 0.08-0.97; p<0.05). Vildagliptin as an add-on to insulin treatment for 24months was well tolerated and led to sustained reductions in HbA1c, the dose and number of insulin injections, and the risk of hypoglycemia.

Rasagiline (N-propargyl-1 (R)-aminoindan) is a selective, potent irreversible inhibitor of MAO-B that possesses neuroprotective and anti-apoptotic properties in a variety of in vitro and in vivo animal models relevant to Parkinson's disease (PD). Several randomized controlled clinical trials have demonstrated the safety and efficacy of rasagiline as monotherapy in PD and as adjunctive therapy for patients receiving levodopa. In addition, the 1-year randomized, delayed-start analysis of the TEMPO study suggests that rasagiline may slow the rate of progression of PD. The randomized delayed-start paradigm has potential to differentiate short-term symptomatic effects from long-term effects of anti-parkinsonian agents. In the future, long-term trials to examine the potential disease-modifying effects of rasagiline, which incorporate biological markers as well as clinical endpoints, may further elucidate the role of rasagiline in the treatment of both early and advanced PD.

Children with Prader-Willi syndrome (PWS) have abnormal body composition and impaired growth. Short-term GH treatment has beneficial effects. The aim of the study was to investigate effects of long-term continuous GH treatment on body composition, growth, bone maturation, and safety parameters. We conducted a multicenter prospective trial. Fifty-five children with a mean +/- sd age of 5.9 +/- 3.2 yr were followed during 4 yr of continuous GH treatment (1 mg/m(2) . d). Data were annually obtained in one center: fat percentage (fat%) and lean body mass (LBM) by dual-energy x-ray absorptiometry, height, weight, head circumference, bone age, blood pressure, and fasting IGF-I, IGF binding protein-3, glucose, insulin, glycosylated hemoglobin, total cholesterol, high-density lipoprotein, and low-density lipoprotein. sd scores (SDS) were calculated according to Dutch and PWS reference values (SDS and SDS(PWS)). Fat%SDS was significantly lower after 4 yr of GH treatment (P < 0.0001). LBMSDS significantly increased during the first year (P = 0.02) but returned to baseline values the second year and remained unchanged thereafter. Mean +/- sd height normalized from -2.27 +/- 1.2 SDS to -0.24 +/- 1.2 SDS (P < 0.0001). Head circumference SDS increased from -0.79 +/- 1.0 at start to 0.07 +/- 1.1 SDS after 4 yr. BMISDS(PWS) significantly decreased. Mean +/- sd IGF-I and the IGF-I/IGF binding protein-3 ratio significantly increased to 2.08 +/- 1.1 and 2.32 +/- 0.9 SDS, respectively. GH treatment had no adverse effects on bone maturation, blood pressure, glucose homeostasis, and serum lipids. Our study in children with PWS shows that 4 yr of continuous GH treatment (1 mg/m(2) . d) improves body composition by decreasing fat%SDS and stabilizing LBMSDS and head circumference SDS and normalizes heightSDS without adverse effects. Thus, long-term continuous GH treatment is an effective and safe therapy for children with PWS.

Purpose To determine the efficacy and safety of diode transscleral cyclophotocoagulation (TSCPC) after tube shunt failure. Patients and Methods The patient population consisted of 32 eyes of 31 patients with uncontrolled glaucoma. Each eye had a previously implanted aqueous tube shunt and was currently on maximally tolerated medication. Each eye also underwent TSCPC treatment using the Iridex (Mountain View, CA) diode laser with a maximum of 360 degrees of treatment. All 31 charts were reviewed for data pertaining to demographics, treatment, ocular history, and follow-up clinical examinations. Safety was evaluated by complication data. Efficacy was evaluated in terms of TSCPC treatment parameters (number of laser applications, laser power, application duration, and degrees of ciliary body treated), intraocular pressure (IOP), number of hypotensive medications, and any further treatment required. Results With a mean (SD) follow-up of 17.1 (16.3) (median = 11.7) months from the last treatment, the mean IOP decreased from 28.6 (10.2) mmHg to 16.8 (7.5) mmHg (35% reduction) at 3 months (n = 30, p < 0.0001) and to 14.7 (7.9) mmHg (43% reduction) at 1 year (n = 13, p < 0.0001). Complications included hypotony (n = 4), hyphema (n = 2), failed corneal transplant (n = 1), and loss of light perception (n = 5). Conclusions TSCPC has a significant ocular hypotensive effect on glaucoma refractory to both tube shunt and medical therapy. The safety of this intervention remains unclear in this high risk patient population and warrants further study. PMID:21336148

The purpose of this study was to evaluate the long-term safety and efficacy of aripiprazole in treating irritability in pediatric patients (6-17 years) with autistic disorder (AD) in Japan. In this open-label extension study, patients who had completed a previous randomized, double-blind, placebo-controlled 8-week study were enrolled and were flexibly dosed with aripiprazole (1-15 mg/day) until the new indication of irritability in pediatric autism spectrum disorder was approved in Japan. Seventy (81%) out of 86 enrolled patients completed week-48 assessments. The mean duration of treatment was 694.9 days. The mean daily dose of aripiprazole over the treatment period was 7.2 mg and the mean of the final dose was 8.5 mg. The most common treatment-emergent adverse events (TEAE; ≥20%) included nasopharyngitis, somnolence, influenza, and increased weight. The majority of these TEAE were mild or moderate in severity, and there were no deaths, and no clinically relevant findings in laboratory values except prolactin decrease, vital signs, height, or ECG parameters. At week 48 (observed case), the mean change from baseline in the Irritability subscale score for the Aberrant Behavior Checklist Japanese Version was -6.3 in prior placebo patients and -2.6 in prior aripiprazole patients. Aripiprazole was generally safe, well tolerated, and effective in the long-term treatment of irritability associated with AD in Japanese pediatric patients. © 2017 The Authors.

The aim of this study was to assess antidepressant efficacy and safety of venlafaxine extended release in Japanese patients with major depressive disorder (MDD). We carried out a double-blinded, placebo-controlled, randomized study using fixed (75 mg/day) and flexible (75-225 mg/day, most patients attained to 225 mg/day) doses, followed by the long-term, open-labeled, extension study. Outpatients aged at least 20 years diagnosed with MDD were included. The primary efficacy measure was change from baseline in the Hamilton Rating Scale for Depression (HAM-D17) score at week 8; secondary efficacy measures included the Montgomery-Åsberg Depression Rating Scale, the Quick Inventory of Depressive Symptomatology self-report version, HAM-D6, and Clinical Global Impression scales in the double-blinded study. Overall, 538 patients were randomized; significant differences were observed in the primary efficacy variable in the fixed-dose group (-10.76; P=0.031), but not in the flexible-dose (-10.37; P=0.106) group compared with placebo (-9.25). However, the flexible-dose group showed significant efficacy in several secondary measures. Treatment-related adverse events in the treatment period were 51.7 and 67.8% in the fixed-dose and flexible-dose groups, respectively, versus 38.8% with placebo. Throughout the study period, no Japanese-specific adverse events were observed. Thus, venlafaxine extended release was efficacious and safe for MDD treatment in Japan.

Study Objectives: Studies have shown pharmacokinetic differences for hypnotics in women compared to men, but few studies have assessed either short-or long-term differences in efficacy and safety. Methods: To evaluate gender differences in the efficacy and safety of chronic nightly zolpidem (10 mg), we did a post hoc assessment of a large clinical trial. In the trial, participants with primary insomnia (n = 89), ages 23–70, meeting DSM-IV-TR criteria for primary insomnia were randomized, double blind, to nightly zolpidem, 10 mg (n = 47) or placebo (n = 42) 30 minutes before bedtime nightly for 12 months. Polysomnographic sleep on 2 nights in months 1 and 8 and likelihood of next-day sleepiness, rebound insomnia, and dose escalation were evaluated in months 1, 4, and 12. Results: Relative to placebo, zolpidem significantly increased sleep efficiency and reduced sleep latency and wake after sleep onset assessed at months 1 and 8, with no differences in efficacy between women and men and no diminution of efficacy over months. On a next-day multiple sleep latency test (MSLT), no residual sedation was observed for either women or men. No rebound insomnia or dose escalation was seen with no gender differences in either. Conclusions: In adults with primary insomnia, nightly zolpidem administration showed no gender differences in acute or chronic efficacy or in next-day sleepiness. Zolpidem remained efficacious and safe across 12 months.

Endothelial progenitor cells (EPCs) participate in angiogenesis and induce favorable micro-environments for tissue regeneration. The efficacy of EPCs in regenerative medicine is extensively studied; however, their safety profile remains unknown. Therefore, our aims were to evaluate the safety profile of human peripheral blood-derived EPCs (hEPCs) and to assess the long-term efficacy of hEPCs in bone tissue engineering. hEPCs were isolated from peripheral blood, cultured and characterized. β tricalcium phosphate scaffold (βTCP, control) or 10 6 hEPCs loaded onto βTCP were transplanted in a nude rat calvaria model. New bone formation and blood vessel density were analyzed using histomorphometry and micro-computed tomography (CT). Safety of hEPCs using karyotype analysis, tumorigenecity and biodistribution to target organs was evaluated. On the cellular level, hEPCs retained their karyotype during cell expansion (seven passages). Five months following local hEPC transplantation, on the tissue and organ level, no inflammatory reaction or dysplastic change was evident at the transplanted site or in distant organs. Direct engraftment was evident as CD31 human antigens were detected lining vessel walls in the transplanted site. In distant organs human antigens were absent, negating biodistribution. Bone area fraction and bone height were doubled by hEPC transplantation without affecting mineral density and bone architecture. Additionally, local transplantation of hEPCs increased blood vessel density by nine-fold. Local transplantation of hEPCs showed a positive safety profile. Furthermore, enhanced angiogenesis and osteogenesis without mineral density change was found. These results bring us one step closer to first-in-human trials using hEPCs for bone regeneration.

Optimal upfront dual antiplatelet therapy (DAPT) duration after complex percutaneous coronary intervention (PCI) with drug-eluting stents (DES) remains unclear. This study investigated the efficacy and safety of long-term (≥12 months) versus short-term (3 or 6 months) DAPT with aspirin and clopidogrel according to PCI complexity. The authors pooled patient-level data from 6 randomized controlled trials investigating DAPT durations after PCI. Complex PCI was defined as having at least 1 of the following features: 3 vessels treated, ≥3 stents implanted, ≥3 lesions treated, bifurcation with 2 stents implanted, total stent length >60 mm, or chronic total occlusion. The primary efficacy endpoint was major adverse cardiac events (MACE), defined as the composite of cardiac death, myocardial infarction, or stent thrombosis. The primary safety endpoint was major bleeding. Intention-to-treat was the primary analytic approach. Of 9,577 patients included in the pooled dataset for whom procedural variables were available, 1,680 (17.5%) underwent complex PCI. Overall, 85% of patients received new-generation DES. At a median follow-up time of 392 days (interquartile range: 366 to 710 days), patients who underwent complex PCI had a higher risk of MACE (adjusted hazard ratio [HR]: 1.98; 95% confidence interval [CI]: 1.50 to 2.60; p < 0.0001). Compared with short-term DAPT, long-term DAPT yielded significant reductions in MACE in the complex PCI group (adjusted HR: 0.56; 95% CI: 0.35 to 0.89) versus the noncomplex PCI group (adjusted HR: 1.01; 95% CI: 0.75 to 1.35; p interaction  = 0.01). The magnitude of the benefit with long-term DAPT was progressively greater per increase in procedural complexity. Long-term DAPT was associated with increased risk for major bleeding, which was similar between groups (p interaction  = 0.96). Results were consistent by per-treatment landmark analysis. Alongside other established clinical risk factors, procedural complexity is an

Anakinra is approved for the treatment of RA and cryopyrin-associated periodic syndromes (CAPS). While the anakinra safety profile is well established in RA, the long-term safety profile in severe CAPS is less well documented and will therefore be discussed in this report. A prospective, open-label, single centre, clinical cohort study was conducted at the National Institutes of Health in the USA, from 2003 to 2010, investigating the efficacy and safety of anakinra treatment for up to 5 years in 43 patients with CAPS. Safety was evaluated using adverse event (AE) reports, laboratory assessments, vital signs and diary reports. In total, 1233 AEs were reported during the study, with a yearly rate of 7.7 AEs per patient. The event rate decreased over time, and dose escalation during the study did not affect AE frequency. Anakinra had similar safety profiles in adults and children. The most frequently reported AEs were typical CAPS disease symptoms such as headache and arthralgia. Injection site reactions occurred mainly during the first month of anakinra treatment. In total, 14 patients experienced 24 serious AEs (SAEs), all of which resolved during the study period. The most common types of SAEs were infections such as pneumonia and gastroenteritis. There were no permanent discontinuations of treatment due to AEs. In this study anakinra treatment of patients with severe CAPS for up to 5 years was safe and well tolerated both in paediatric and adult patients, with most AEs emerging during the first months after treatment initiation.

A prospective, open-label, single centre, clinical cohort study was conducted at the National Institutes of Health in the USA, from 2003 to 2010, investigating the efficacy and safety of anakinra treatment for up to 5 years in 43 patients with CAPS. Safety was evaluated using adverse event (AE) reports, laboratory assessments, vital signs and diary reports. Results. In total, 1233 AEs were reported during the study, with a yearly rate of 7.7 AEs per patient. The event rate decreased over time, and dose escalation during the study did not affect AE frequency. Anakinra had similar safety profiles in adults and children. The most frequently reported AEs were typical CAPS disease symptoms such as headache and arthralgia. Injection site reactions occurred mainly during the first month of anakinra treatment. In total, 14 patients experienced 24 serious AEs (SAEs), all of which resolved during the study period. The most common types of SAEs were infections such as pneumonia and gastroenteritis. There were no permanent discontinuations of treatment due to AEs. Conclusion. In this study anakinra treatment of patients with severe CAPS for up to 5 years was safe and well tolerated both in paediatric and adult patients, with most AEs emerging during the first months after treatment initiation.

Studies have shown pharmacokinetic differences for hypnotics in women compared to men, but few studies have assessed either short-or long-term differences in efficacy and safety. To evaluate gender differences in the efficacy and safety of chronic nightly zolpidem (10 mg), we did a post hoc assessment of a large clinical trial. In the trial, participants with primary insomnia (n = 89), ages 23-70, meeting DSM-IV-TR criteria for primary insomnia were randomized, double blind, to nightly zolpidem, 10 mg (n = 47) or placebo (n = 42) 30 minutes before bedtime nightly for 12 months. Polysomnographic sleep on 2 nights in months 1 and 8 and likelihood of next-day sleepiness, rebound insomnia, and dose escalation were evaluated in months 1, 4, and 12. Relative to placebo, zolpidem significantly increased sleep efficiency and reduced sleep latency and wake after sleep onset assessed at months 1 and 8, with no differences in efficacy between women and men and no diminution of efficacy over months. On a next-day multiple sleep latency test (MSLT), no residual sedation was observed for either women or men. No rebound insomnia or dose escalation was seen with no gender differences in either. In adults with primary insomnia, nightly zolpidem administration showed no gender differences in acute or chronic efficacy or in next-day sleepiness. Zolpidem remained efficacious and safe across 12 months.

2018-01-01

With a growing number of disease-modifying therapies becoming available for relapsing multiple sclerosis, there is an important need to gather real-world evidence data regarding long-term treatment effectiveness and safety in unselected patient populations. Although not providing as high a level of evidence as randomized controlled trials, and prone to bias, real-world studies from observational studies or registries nevertheless provide crucial information on real-world outcomes of a given therapy. In addition, evaluation of treatment satisfaction and impact on quality of life are increasingly regarded as complementary outcome measures. Fingolimod was the first oral disease-modifying therapy approved for relapsing multiple sclerosis. This review aims to summarize current knowledge on the long-term effectiveness and safety outcomes of multiple sclerosis patients on fingolimod. Impact on treatment satisfaction and quality of life will be discussed according to available data. PMID:29317850

An open-label, long-term study evaluated safety and tolerability of azilsartan medoxomil/chlorthalidone (AZL-M/CLD) vs olmesartan/hydrochlorothiazide (OLM/HCTZ) in hypertensive participants with stage 3 chronic kidney disease. Initial therapy was AZL-M/CLD 20/12.5 mg (n = 77) or OLM/HCTZ 20/12.5 mg (n = 76), but could be up-titrated (AZL-M/CLD to 40/25 mg; OLM/HCTZ to 40/25 mg [US] or 20/25 mg [Europe]) with other agents added during weeks 4-52. Primary endpoint was proportion of participants with ≥ 1 adverse event (AE) through week 52. Baseline demographics were similar. AEs did not differ between groups (88.3%, AZL-M/CLD vs 76.3%, OLM/HCTZ; P = .058). AZL-M/CLD showed greater systolic BP reductions after initial dosing (P = .037) but not during long-term follow-up (P = .588). A greater proportion of participants up-titrated to the highest dose with OLM/HCTZ (48.7%) vs AZL-M/CLD (29.9%) (P = .021) and were taking additional antihypertensive medications (26.3% vs 16.9%). Both AZL-M/CLD and OLM/HCTZ showed similar efficacy and tolerability. ©2018 Wiley Periodicals, Inc.

Resilience Engineering in Critical Long Term Aerospace Software Systems: A New Approach to Spacecraft Software Safety

NASA Astrophysics Data System (ADS)

Dulo, D. A.

Safety critical software systems permeate spacecraft, and in a long term venture like a starship would be pervasive in every system of the spacecraft. Yet software failure today continues to plague both the systems and the organizations that develop them resulting in the loss of life, time, money, and valuable system platforms. A starship cannot afford this type of software failure in long journeys away from home. A single software failure could have catastrophic results for the spaceship and the crew onboard. This paper will offer a new approach to developing safe reliable software systems through focusing not on the traditional safety/reliability engineering paradigms but rather by focusing on a new paradigm: Resilience and Failure Obviation Engineering. The foremost objective of this approach is the obviation of failure, coupled with the ability of a software system to prevent or adapt to complex changing conditions in real time as a safety valve should failure occur to ensure safe system continuity. Through this approach, safety is ensured through foresight to anticipate failure and to adapt to risk in real time before failure occurs. In a starship, this type of software engineering is vital. Through software developed in a resilient manner, a starship would have reduced or eliminated software failure, and would have the ability to rapidly adapt should a software system become unstable or unsafe. As a result, long term software safety, reliability, and resilience would be present for a successful long term starship mission.

Background Methotrexate (MTX) has been used to treat psoriasis for over half a century. Even so, clinical data characterising its efficacy and safety are sparse. Objective In order to enhance the available evidence, we conducted two meta-analyses, one for efficacy and one for safety outcomes, respectively, according to PRISMA checklist. (Data sources, study criteria, and study synthesis methods are detailed in Methods). Results In terms of efficacy, only eleven studies met criteria for study design and passed a Cochrane risk of bias analysis. Based on this limited dataset, 45.2% [95% confidence interval 34.1–60.0] of patients achieve PASI75 at primary endpoint (12 or 16 weeks, respectively, n = 705 patients across all studies), compared to a calculated PASI75 of 4.4 [3.5–5.6] for placebo, yielding a relative risk of 10.2 [95% C.I. 7.1–14.7]. For safety outcomes, we extended the meta-analysis to include studies employing the same dose range of MTX for other chronic inflammatory conditions, e.g. rheumatoid arthritis, in order not to maximise capture of relevant safety data. Based on 2763 patient safety years, adverse events (AEs) were found treatment limiting in 6.9 ± 1.4% (mean ± s.e.) of patients treated for six months, with an adverse effect profile largely in line with that encountered in clinical practice. Finally, in order to facilitate prospective clinical audit and to help generate long-term treatment outcomes under real world conditions, we also developed an easy to use documentation form to be completed by patients without requirement for additional staff time. Limitations Meta-analyses for efficacy and safety, respectively, employed non-identical selection criteria. Conclusions These meta-analyses summarise currently available evidence on MTX in psoriasis and should be of use to gauge whether local results broadly fall within outcomes. PMID:27168193

Safety and Efficacy of Microinvasive Glaucoma Surgery

Chen, David Z.

2017-01-01

Microinvasive glaucoma surgery (MIGS) is emerging as a new therapeutic option for glaucoma patients who wish to reduce their medication burden and avoid the postoperative complications of conventional glaucoma filtration surgery. These devices differ in terms of their efficacy and safety profile. Schlemm's canal devices have the most favorable safety profile at the compromise of modest efficacy, while subconjunctival and suprachoroidal devices are potentially more effective at lowering the intraocular pressure at the expense of a higher rate of complications. This review consolidates the latest evidence on the efficacy and safety of the MIGS devices in clinical use and provides an overview on upcoming devices which would likely also become viable treatment options in the near future. These clinical data would assist a glaucoma surgeon in selecting the most appropriate MIGS device for each patient based on the glaucoma severity and patient expectations. PMID:28512578

To assess the safety of long-term cevimeline treatment of radiation-induced xerostomia in patients with head-and-neck cancer; and to assess the efficacy of cevimeline in these patients. A total of 255 adults with head-and-neck cancer who had received more than 40 Gy of radiation 4 months or more before entry and had clinically significant salivary gland dysfunction received cevimeline hydrochloride 45 mg t.i.d. orally for 52 weeks. Adverse events (AEs), their severity, and their relationship to the study medication were assessed by each investigator. The efficacy assessment was based on subjects' global evaluation of oral dryness on a scale of 0 (none) to 3 (severe). Overall, 175 subjects (68.6%) experienced expected treatment-related AEs, most mild to moderate. The most frequent was increased sweating (47.5%), followed by dyspepsia (9.4%), nausea (8.2%), and diarrhea (6.3%). Fifteen subjects (5.9%) experienced Grade 3 treatment-related AEs, of which the most frequent was increased sweating. Eighteen subjects (7.1%) reported at least one serious AE, and 45 subjects (17.6%) discontinued study medication because of an AE. The global efficacy evaluation at the last study visit showed that cevimeline improved dry mouth in most subjects (59.2%). Significant improvement was seen at each study visit in the mean change from baseline of the numeric global evaluation score (p < 0.0001). Cevimeline 45 mg t.i.d. was generally well tolerated over a period of 52 weeks in subjects with xerostomia secondary to radiotherapy for cancer in the head-and-neck region.

Medication errors continue to be a major issue in the health care system, including in long-term care facilities. While many hospitals and health systems have developed methods to identify, track, and prevent these errors, long-term care facilities historically have not invested in these error-prevention strategies. The objective of this study was two-fold: 1) to develop a set of medication-safety process measures for dispensing in a long-term care pharmacy, and 2) to analyze the data from those measures to determine the relative safety of the process. The study was conducted at In Touch Pharmaceuticals in Valparaiso, Indiana. To assess the safety of the medication-use system, each step was documented using a comprehensive flowchart (process flow map) tool. Once completed and validated, the flowchart was used to complete a "failure modes and effects analysis" (FMEA) identifying ways a process may fail. Operational gaps found during FMEA were used to identify points of measurement. The research identified a set of eight measures as potential areas of failure; data were then collected on each one of these. More than 133,000 medication doses (opportunities for errors) were included in the study during the research time frame (April 1, 2014, and ended on June 4, 2014). Overall, there was an approximate order-entry error rate of 15.26%, with intravenous errors at 0.37%. A total of 21 errors migrated through the entire medication-use system. These 21 errors in 133,000 opportunities resulted in a final check error rate of 0.015%. A comprehensive medication-safety measurement program was designed and assessed. This study demonstrated the ability to detect medication errors in a long-term pharmacy setting, thereby making process improvements measureable. Future, larger, multi-site studies should be completed to test this measurement program.

To evaluate the long-term efficacy of submandibular gland transfer for prevention of xerostomia after radiotherapy for nasopharyngeal carcinoma. Sixty-five cases of nasopharyngeal carcinoma patients were randomly divided into study group of 32 patients and control group of 33 patents. The submandibular gland was transferred to submental region on 32 cases with nasopharyngeal carcinoma before receiving conventional radiotherapy and a block was used to cover the submental region. Before radiotherapy, two groups of submandibular gland function was detected by imaging of the submandibular gland. At 60 months after radiotherapy, submandibular gland function was detected by 99mTc radionuclide scanning, the questionnaire about the degree of xerostomia was investigated respectively. Five-year survival rate was counted. After following up for 60 months, submandibular gland uptake and secretion function in the study group was significantly higher than that in the control group, there was significant difference between the two groups (P < 0.01) respectively. The incidence of moderate or severe xerostomia in the study group was significantly lower than that in the control group (15.4% vs 76.9%, P < 0.01). Five-year survival rate of the study group and control group was 81.3% and 78.8% respectively, there was no significant difference between the two groups (P > 0.05). The long-term efficacy of submandibular gland transfer for prevention of xerostomia after radiotherapy for nasopharyngeal carcinoma was well. It could improve the quality of life in nasopharyngeal carcinoma patients after radiotherapy, and did not affect the long-term efficacy of nasopharyngeal carcinoma.

In a previous three-month study of Meriva, a proprietary curcumin-phosphatidylcholine phytosome complex, decreased joint pain and improvement in joint function were observed in 50 osteoarthritis (OA) patients. Since OA is a chronic condition requiring prolonged treatment, the long-term efficacy and safety of Meriva were investigated in a longer (eight months) study involving 100 OA patients. The clinical end points (Western Ontario and McMaster Universities [WOMAC] score, Karnofsky Performance Scale Index, and treadmill walking performance) were complemented by the evaluation of a series of inflammatory markers (interleukin [IL]-1beta, IL-6, soluble CD40 ligand [sCD40L], soluble vascular cell adhesion molecule (sVCAM)-1, and erythrocyte sedimentation rate [ESR]). This represents the most ambitious attempt, to date, to evaluate the clinical efficacy and safety of curcumin as an anti-inflammatory agent. Significant improvements of both the clinical and biochemical end points were observed for Meriva compared to the control group. This, coupled with an excellent tolerability, suggests that Meriva is worth considering for the long-term complementary management of osteoarthritis.

Chronic pain is an important yet overlooked non-motor symptom of Parkinson's disease (PD), caused by an imbalance of the dopaminergic and glutamatergic systems. Safinamide has a multimodal mechanism of action, dopaminergic (reversible MAO-B inhibition) and non-dopaminergic (modulation of the abnormal glutamate release), that might be beneficial for both motor and non-motor symptoms. To investigate the long-term (2-year) efficacy of safinamide on PD chronic pain and to confirm the positive effects observed after 6 months of treatment. This is a post hoc analysis of the data from the 2-year study 018, focused on the reduction of concomitant pain treatments and on the scores of pain-related items of the Parkinson's disease quality of life questionnaire (PDQ-39). Safinamide, compared with placebo, significantly improved the PDQ-39 items 37 ("painful cramps or spasm," p = 0.0074) and 39 ("unpleasantly hot or cold," p = 0.0209) and significantly reduced the number of concomitant pain treatments by 26.2% (p = 0.005). A significantly greater proportion of patients in the safinamide group was not using pain drugs after 2 years of treatment (p = 0.0478). The positive effects of safinamide on PD chronic pain were maintained in the long term. Further investigations are desirable to confirm their clinical relevance. Zambon SpA.

Background: In Phase 3 double-blind trials (MS-F203 and MS-F204), dalfampridine extended release tablets 10 mg twice daily (dalfampridine-ER; prolonged-release fampridine in Europe; fampridine modified or sustained release elsewhere) improved walking speed relative to placebo in patients with multiple sclerosis (MS). Objectives: Evaluation of long-term safety and efficacy of dalfampridine-ER in open-label extensions (MS-F203EXT, MS-F204EXT). Methods: Patients received dalfampridine-ER 10 mg twice daily; and had Timed 25-Foot Walk (T25FW) assessments at 2, 14 and 26 weeks, and then every 6 months. Subjects were categorized as dalfampridine-ER responders or non-responders, based on their treatment response in the double-blind parent trials that assessed T25FW. Results: We had 269 patients enter MS-F203EXT and 154 patients complete it; for a maximum exposure of 5 years. We had 214 patients enter MS-F204EXT and 146 complete it; for a maximum exposure of 3.3 years. No new safety signals emerged and dalfampridine-ER tolerability was consistent with the double-blind phase. Improvements in walking speed were lost after dalfampridine-ER was discontinued in the parent trial, but returned by the 2-week assessment after re-initiation of the drug. Throughout the extensions, mean improvement in walking speed declined, but remained improved, among the double-blind responders as compared with non-responders. Conclusions: The dalfamipridine-ER safety profile was consistent with the parent trials. Although walking speed decreased over time, dalfampridine-ER responders continued to show improved walking speed, which was sustained compared with non-responders. PMID:25583832

Neurogenic orthostatic hypotension (nOH) is associated with insufficient norepinephrine release in response to postural change. The objective of this study was to evaluate the long-term safety and durability of efficacy of the norepinephrine precursor droxidopa in patients with symptomatic nOH. This multinational study consisted of 3 sequential phases: a 3-month open-label droxidopa treatment phase followed by a 2-week double-blind, placebo-controlled withdrawal phase, and a 9-month open-label extension phase in which all patients received droxidopa. Patients were adults diagnosed with symptomatic nOH associated with Parkinson's disease, multiple system atrophy, pure autonomic failure, dopamine β-hydroxylase deficiency, or nondiabetic autonomic neuropathy. Efficacy was evaluated using patient- and investigator-reported questionnaire responses and the orthostatic standing test. Safety was assessed through adverse event (AE) reports and vital signs. A total of 102 patients received treatment with droxidopa. Initial improvements from baseline in patient-reported nOH symptom severity and impact on daily activities, evaluated using the Orthostatic Hypotension Questionnaire, exceeded 50% and were maintained throughout the 12-month study. Decreased nOH severity was also reflected in clinician and patient ratings on the Clinical Global Impression questionnaire. Standing systolic and diastolic blood pressures were increased from baseline throughout the study with droxidopa treatment. The most frequently reported AEs were falls, urinary tract infection, and headache. There was a low incidence (≤2%) of cardiac AEs (eg, first-degree atrioventricular block, supraventricular extrasystoles). Long-term, open-label treatment with droxidopa for up to 12 months was generally well tolerated and provided durable improvements in nOH signs and symptoms.

Patients with chronic kidney disease (CKD) have elevated bleeding and ischemic outcomes. We aim to assess the short- and long-term efficacy and safety of bivalirudin compared to heparin plus glycoprotein IIb/IIIa inhibitors (GPIs) in coronary artery disease (CAD) patients with CKD. Randomized trials were searched in PubMed, Cochrane, and Embase databases up to January 2017. Among the trials retrieved, efficacy endpoints were defined as mortality, myocardial infarction (MI), repeat revascularization, stent thrombosis, and major adverse cardiac events (MACEs). Safety endpoints were reported as non-coronary artery bypass grafting (CABG) related major bleeding and thrombolysis in myocardial infarction (TIMI) major bleeding. Risk ratio (RR) and 95% confidence interval (CI) were calculated for each outcome using a fixed effect model. Five studies with a total of 3796 patients were included. In short-term follow up (30 days), bivalirudin significantly reduced non-CABG related major bleeding (p=0.0004) and TIMI major bleeding (p=0.007) compared to heparin plus GPIs. No significant differences were observed in rates of mortality, MI, repeat revascularization, stent thrombosis, and MACEs between the two groups in short- and long-term follow up (6 months to 3 years). In patients with ST elevated myocardial infarction (STEMI) with concurrent CKD, the decreased non-CABG related major bleeding (p=0.04) without increasing ischemic events was also observed after short-term follow up. (1) Bivalirudin is safer than and as effective as heparin plus GPIs in CAD patients with CKD. (2) Impaired renal function does not affect the safety benefits of bivalirudin. (3) Similar efficacy profiles were identified between the two groups after both short- and long-term follow up in the CAD patients with CKD. Copyright © 2017 Japanese College of Cardiology.

Cañas, Fernando; Möller, Hans-Jürgen

2010-09-01

Although atypical antipsychotics have beneficial efficacy and tolerance, non-adherence and partial adherence remain in patients treated for schizophrenia. Long-acting injectable or depot atypical antipsychotics offer better medication adherence and tolerability advantages. Currently, two drugs are available for the treatment of schizophrenia, risperidone long-acting injectable (RLAI) and olanzapine pamoate (OP). Short- and long-term safety and tolerability data on RLAI and OP from January 2006 through September 2009 were reviewed by performing Medline and PubMed searches, reviewing abstracts and poster presentations, and viewing available material from the FDA and European Medicines Agency. RLAI and OP show good short- and long-term safety when treating patients with schizophrenia, with uncommon discontinuation due to adverse effects. RLAI and OP data show rare problems with injection site reactions and patients exposed to injectable treatments prefer to continue injections. Infrequent but serious post-injection delirium sedation syndrome occurred after 1% of OP injections. Weight gain was generally higher among patients treated with OP versus RLAI. Healthcare providers, patients and family members should be made aware of the safety and benefits of long-acting injectable atypical antipsychotics in order to diminish the unnecessary restrictions of these therapies for patients with schizophrenia.

Transcatheter renal sympathetic denervation (RDN) is a novel technology/therapy in treating resistant hypertension. The present study aims to evaluate the safety and short-term efficacy of RDN for the treatment of resistant hypertension in a Chinese population. This prospective single-center pilot study was the first one conducted in China with Medtronic Ardian Symplicity Catheter System. Eight patients (6 males and 2 females) with resistant hypertension underwent RDN at our hospital from February to April 2012. All patients were followed up at one month and three months post-RDN. Blood pressure, use of antihypertensive medications, renal function and complications were recorded and analyzed. At one month and three months post-RDN, 24-hour ambulatory blood pressure monitoring showed mean systolic blood pressure and diastolic blood pressure decreased 10 (0 - 18) 13 (3 - 19) and 8 (-2 - 15), 9 (2 - 16) mm Hg throughout 24 hours respectively (P < 0.05, vs baseline). The number of drugs decreased from 4.3 ± 0.5 to 2.8 ± 0.9 and 2.5 ± 0.7 post-RSD respectively (P < 0.01). There was no significant change of renal function (P > 0.05). No complications were observed. The preliminary results revealed that RDN was safe and effective for the treatment of resistant hypertension in the Chinese population during a 3-month follow-up. Further large and long-term studies are warranted.

Droxidopa has been approved for the treatment of neurogenic orthostatic hypotension (NOH) under the US Food and Drug Administration accelerated approval program, which warrants confirmatory evidence on long-term efficacy of droxidopa. Hereby, we synthesize evidence from published randomized controlled trials (RCTs) about the safety and efficacy of droxidopa for patients with neurogenic orthostatic hypotension. A computer literature search of PubMed, Scopus, Web of Science, and Cochrane Central was conducted using relevant keywords. Records were screened for eligible studies and data were extracted and synthesized using Review Manager version 5.3 for Windows. Subgroup analysis and sensitivity analysis were conducted to investigate long-term durability of droxidopa against placebo. Four RCTs with a total of 485 patients (droxidopa, n = 246; placebo, n = 239) were eligible for the final analysis. The mean difference (MD) of change in the main outcomes from baseline to endpoint favored droxidopa than placebo [Orthostatic Hypotension Questionnaire (OHQ) MD -0.61, P = 0.004; dizziness/lightheadedness score MD -0.83, P = 0.008; and standing systolic blood pressure (SBP) MD 4.09, P = 0.03]. The efficacy of droxidopa decreased gradually after 2 weeks, and its statistical significance was lost after 8 weeks (OHQ score MD -0.18, P = 0.61; dizziness/lightheadedness score MD -0.71, P = 0.11; and standing SBP MD 2.96, P = 0.29). None of the adverse events were significantly higher in the case of droxidopa compared to placebo. Droxidopa is a safe and effective drug for the short-term management of NOH symptoms. However, current evidence is insufficient to confirm the efficacy of droxidopa for long-term use. Therefore, further studies with increased sample size are needed.

The long-term potential of solifenacin and mirabegron combination treatment for patients with overactive bladder (OAB) has not been previously assessed. To evaluate the safety and efficacy of solifenacin succinate 5mg plus mirabegron 50mg tablets (combination treatment) versus solifenacin or mirabegron monotherapy in patients with OAB over 12 mo. Randomised, double-blind, multicentre, phase 3 trial (SYNERGY II) of patients with "wet" OAB symptoms (urinary frequency and urgency with incontinence) for ≥3 mo. The study was conducted from March 2014 to September 2016; with 1829 patients randomised. The full analysis set was comprised of 1794 patients. The primary objective was safety, measured as treatment-emergent adverse events (TEAEs). Efficacy was measured as the change from baseline to the end of treatment in the mean number of incontinence episodes/24h and micturitions/24h. The median age was 60 yr (range 19-86 yr) and 1434 patients (80%) were female. Overall, 856 patients (47%) experienced ≥1 TEAE. TEAE frequency was slightly higher in the combination group (596 patients, 49%; mirabegron 126 patients, 41%; solifenacin 134 patients, 44%). Serious TEAEs were reported by 67 patients (3.7%); one was considered possibly treatment-related (mirabegron group, atrial fibrillation). Dry mouth was the most common TEAE (combination 74 patients, 6.1%; solifenacin 18 patients, 5.9%; mirabegron 12 patients, 3.9%). Combination therapy was statistically superior to mirabegron and solifenacin for the number of incontinence episodes (vs mirabegron: adjusted mean difference [AMD] -0.5, 95% confidence interval [CI] -0.7 to -0.2, p<0.001; vs solifenacin: AMD -0.1, 95% CI -0.4 to 0.1, p=0.002) and micturitions (vs mirabegron: AMD -0.5, 95% CI -0.8 to -0.2, p<0.001; vs solifenacin: AMD -0.4, 95% CI -0.7 to -0.1, p=0.004). Mirabegron and solifenacin combination treatment for OAB symptoms was well tolerated over 12 mo and led to efficacy improvements over each monotherapy. This

To add to the data for long-term reverse pull headgear (RPHG) outcomes and further explore possible variables that could be predictors of long-term failure. Cephalometric radiographs of 41 Class III malocclusion children treated with RPHG (face mask) were evaluated before and immediately after treatment; at 5 years posttreatment; and, for 18 patients, at 10 years posttreatment. Patients were assigned to success or failure groups according to positive or negative overjet at the longest available recall. Seventy-five percent of the patients maintained positive overjet, whereas 25% outgrew the correction. In a stepwise discriminant analysis, a large mandible and vertical positioning of the maxilla and mandible so that mandibular growth would be projected more horizontally were the major indicators of unfavorable later mandibular growth. Patients who experienced downward-backward rotation of the mandible during RPHG treatment were more likely to be categorized in the failure group. The age at which treatment began had no effect on long-term success and failure for patients younger than 10 years, but the percentage of successful treatment decreased after that age. When RPHG treatment is used for all but the most obviously prognathic children to correct anterior cross-bite in the early mixed dentition, positive overjet is maintained long-term in 70%-75% of cases, whereas 25%-30% of cases relapse into reverse overjet mainly because of increased horizontally directed and often late mandibular growth. Up to age 10, the time at which RPHG treatment began does not appear to be a major factor in long-term success in maintaining positive overjet.

The present study aimed to examine the long-term efficacy and safety of rotigotine treatment for restless legs syndrome (RLS), as well as the rate of clinically significant augmentation, in a 1-year open-label study of Japanese subjects. Japanese patients with RLS who had been treated with rotigotine or placebo in a double-blind trial were enrolled in a 1-year, open-label, uncontrolled extension study and treated with rotigotine at a dose of up to 3 mg/24 h after an 8-week titration phase. Outcomes included International Restless Legs Syndrome Study Group rating scale (IRLS scale), Pittsburgh Sleep Quality Index (PSQI), safety, and investigator-/expert panel-assessed augmentation (including Augmentation Severity Rating Scale). Overall, 185 patients entered the open-label study and 133 completed the study. IRLS and PSQI total scores improved throughout the 52-week treatment period (IRLS, from 23.2±5.1 to 7.8±7.6 and PSQI, from 8.0±3.1 to 5.0±2.9). Treatment-emergent adverse events were mild to moderate in severity, and included application site reactions (52.4%) and nausea (28.6%). Clinically significant augmentation occurred in five patients (2.7%). These results indicate a good long-term efficacy of rotigotine for treating RLS, with a relatively low risk of clinically significant augmentation. Copyright © 2012 Elsevier Inc.

We assessed the safety of long-term varenicline administration for smoking cessation. In this randomized, double-blind, multicenter trial, eligible adult smokers (18-75 years) who smoked an average of > or =10 cigarettes/day were randomized to either varenicline 1 mg twice daily (BID) or placebo for 52 weeks. Subjects made weekly clinic visits until week 8, and then every 4 weeks until week 52, with a follow-up visit at week 53. The target quit date was the morning of the week 1 clinic visit. Brief counseling was provided at each visit, and vital signs, adverse events (AEs), and smoking status were documented. Other laboratory measures were collected at specified visits. A total of 251 subjects were randomized to varenicline and 126 to placebo. Approximately half of the subjects in each arm completed the study (53.8% varenicline; 46.8% placebo). Treatment-emergent AEs were observed in 96.4% of varenicline- and 82.5% of placebo-treated subjects during the study. Common varenicline-associated AEs were nausea (40.2%), abnormal dreams (22.7%), and insomnia (19.1%). Most AEs were considered mild or moderate in intensity. AEs leading to discontinuation of varenicline treatment included nausea (7.6%), insomnia (3.2%), and abnormal dreams (2.4%). A single varenicline-related serious AE, bilateral subcapsular cataracts, was observed. At week 52, 7-day point prevalence abstinence rates were 36.7% (varenicline) and 7.9% (placebo). Varenicline 1 mg BID can be safely administered for up to 1 year. Varenicline was also a more effective smoking cessation aid than placebo throughout the study, supporting both its short- (12-week) and long-term (52-week) efficacy.

To evaluate long-term treatment efficacy and safety of one-time telemedicine consultations for nonacute headaches. We randomized, allocated, and consulted nonacute headache patients via telemedicine (n = 200) or in a traditional manner (n = 202) in a noninferiority trial. Efficacy endpoints, assessed by questionnaires at 3 and 12 months, included change from baseline in Headache Impact Test-6 (HIT-6) (primary endpoint) and pain intensity (visual analogue scale [VAS]) (secondary endpoint). The primary safety endpoint, assessed via patient records, was presence of secondary headache within 12 months after consultation. We found no differences between telemedicine and traditional consultations in HIT-6 ( p = 0.84) or VAS ( p = 0.64) over 3 periods. The absolute difference in HIT-6 from baseline was 0.3 (95% confidence interval [CI] -1.26 to 1.82, p = 0.72) at 3 months and 0.2 (95% CI -1.98 to 1.58, p = 0.83) at 12 months. The absolute change in VAS was 0.4 (95% CI -0.93 to 0.22, p = 0.23) after 3 months and 0.3 (95% CI -0.94 to 0.29, p = 0.30) at 12 months. We found one secondary headache in each group at 12 months. The estimated number of consultations needed to miss one secondary headache with the use of telemedicine was 20,200. Telemedicine consultation for nonacute headache is as efficient and safe as a traditional consultation. NCT02270177. This study provides Class III evidence that a one-time telemedicine consultation for nonacute headache is noninferior to a one-time traditional consultation regarding long-term treatment outcome and safety.

A number of second-generation non-sedating antihistamines are used in clinical practices over the world. However, long-term safety and efficacy have not been proved high level evidence based medicine. We have performed an open-label, multicenter, phase III study to evaluate the long-term safety and efficacy of bilastine, a novel non-sedating H 1 -antihistamine for patients with chronic spontaneous urticaria (CSU) or pruritus associated with skin diseases (trial registration no. JapicCTI-142528). Patients aged 18-74 years were treated with bilastine 20 mg once daily for up to 52 weeks. Safety and tolerability were assessed on the basis of adverse events (AE), bilastine-related AE, laboratory tests and vital signs. Efficacy was assessed based on rash score, itch score, overall improvement and quality of life. One hundred and ninety-eight patients enrolled, 122 of whom (61.6%) completed the 52-week treatment period. AE were reported in 64.5% and bilastine-related AE in 2.5% of patients throughout the 52-week treatment period. All AE were mild to moderate in severity. AE associated with the nervous system occurred in 10 patients (5.1%) including seven patients (3.6%) with headache. Somnolence reported in two of these patients (1.0%) was related to bilastine. All efficacy variables improved during treatment with bilastine. In conclusion, long-term treatment with bilastine 20 mg once daily for 52 weeks is safe and well tolerated in Japanese patients with CSU or pruritus associated with skin diseases. Bilastine improved disease symptoms of both conditions early in treatment, and the efficacy was maintained throughout the treatment. © 2016 The Authors.

Pimecrolimus cream (SDZ ASM 981), a nonsteroid inhibitor of inflammatory cytokines, is effective in atopic dermatitis (AD). We assessed whether early treatment of AD signs/symptoms with pimecrolimus could influence long-term outcome by preventing disease flares. Early intervention with pimecrolimus was compared with a conventional AD treatment strategy (ie, emollients and topical corticosteroids). In this 1-year, controlled, double-blind study, 713 AD patients (2-17 years) were randomized 2:1 to a pimecrolimus-based or conventional regimen. Both groups used emollients for dry skin. Early AD signs/symptoms were treated with pimecrolimus cream or, in the conventional treatment group, vehicle to prevent progression to flares. If flares occurred, moderately potent topical corticosteroids were mandated. The primary efficacy endpoint was ranked flares at 6 months. Safety was monitored clinically, and a skin recall-antigen test was performed at study completion. BASELINE CHARACTERISTICS OF THE PATIENTS: The mean age for both groups was approximately 8 years, and the majority of patients had moderate disease at baseline. PATIENT FOLLOW-UP AND EXPOSURE TO STUDY MEDICATION: The mean duration of follow-up (+/-standard error) was 303.7 (+/-5.30) days in the pimecrolimus group and 235.2 (+/-9.40) days in the control group. The discontinuation rate was significantly higher in the control group than in the pimecrolimus group (51.5% vs 31.6% at 12 months), and proportionately more patients with severe or very severe disease discontinued in the control group. The main reason for the higher discontinuation rate in the control group was unsatisfactory therapeutic effect (30.4% vs 12.4%). This resulted in a substantially higher mean number of study medication treatment days in the pimecrolimus group compared with the control group: 211.9 (69.8% of study days) versus 156.0 (66.3% of study days). Of those patients who completed 12 months on study, 14.2% and 7.0% of patients in the

To determine the efficacy and safety of cyclosporine (CyA) in a large national registry-based population of patients with steroid-refractory (SR) acute severe ulcerative colitis (ASUC) and to establish predictors of efficacy and adverse events. Multicenter study of SR-ASUC treated with CyA, based on data from the ENEIDA registry. SR-ASUC patients treated with infliximab (IFX) or sequential rescue therapy (CyA-IFX or IFX-CyA) were used as comparators. Of 740 SR-ASUC patients, 377 received CyA, 131 IFX and 63 sequential rescue therapy. The cumulative colectomy rate was higher in the CyA (24.1%) and sequential therapy (32.7%) than in the IFX group (14.5%; P=0.01) at 3 months and 5 years. There were no differences in early and late colectomy between CyA and IFX in patients treated after 2005. 62% of patients receiving CyA remained colectomy-free in the long term (median 71 months). There were no differences in mortality between CyA (2.4%), IFX (1.5%) and sequential therapy (0%; P=0.771). The proportion of patients with serious adverse events (SAEs) was lower in CyA (15.4%) than in IFX treated patients (26.5%) or sequential therapy (33.4%; P<0.001). This difference in favor of CyA was maintained when only patients treated after 2005 were analyzed. Treatment with CyA showed a lower rate of SAE and a similar efficacy to that of IFX thereby supporting the use of either CyA or IFX in SR-ASUC. In addition, the risk-benefit of sequential CyA-IFX for CyA non-responders is acceptable.

A large and growing population of elderly Koreans with chronic conditions necessitates an increase in long-term care. This study is aimed at investigating the effects of occupational stress, work-centrality, self-efficacy, and job satisfaction on intent to leave among long-term care workers in Korea. We tested the hypothesized structural equation model predicting the intention to quit among long-term care workers in Korea. Survey data were collected from 532 long-term care workers in Seoul, Korea. Results showed that occupational stress was positively associated with intention to leave the job. The study also identified several possible mediators (self-efficacy, work-centrality, job satisfaction) in the relationship between stress and intent to quit. Evidence-based stress management interventions are suggested to help the workers better cope with stressors. Mentoring programs should also be considered for new workers.

Chronic opioid analgesic use often causes opioid-induced constipation (OIC). This open-label extension study evaluated the safety and efficacy of lubiprostone, a chloride channel (ClC-2) activator, for treatment of OIC in patients with chronic noncancer pain. Adults with OIC were enrolled from two 12-week, placebo-controlled, double-blind studies and received lubiprostone 24 μg twice daily for up to 9 months. OIC was defined as < 3 spontaneous bowel movements (SBMs)/week during the 2-week baseline period, of which ≥ 25% were characterized by hard to very hard stool consistency, subjectively incomplete evacuation, and/or moderate or worse straining. Inclusion criteria required consistent treatment with full opioid agonists ≥ 30 days prior to screening and throughout the study. All 439 patients who received lubiprostone were analyzed for safety and efficacy. Overall, 24.6% of patients reported treatment-related adverse events (AEs), most commonly nausea (5.0%), diarrhea (4.6%), headache (1.6%), and vomiting (1.4%). No treatment-related serious AEs were reported. Nausea and diarrhea each led to study discontinuation in 5 patients (1.1%); 2 cases each of nausea and diarrhea were rated as severe. Rescue medication usage decreased from month 1 (33.0%) to month 9 (18.6%). Mean weekly SBM frequency (1.4) was significantly increased from baseline at all months (P < 0.001, range 4.9 to 5.3). Straining, abdominal bloating, abdominal discomfort, stool consistency, constipation severity, and bowel habit regularity were significantly improved from baseline at all months (P < 0.001). Lubiprostone treatment was well tolerated and improved symptoms and signs of OIC in this 9-month, open-label study of patients with chronic noncancer pain. © 2015 World Institute of Pain.

Study Objective: To determine the long-term clinical effectiveness and safety of maxillomandibular advancement (MMA) for the treatment of moderate to severe obstructive sleep apnea (OSA). Methods: A prospective two-center cohort study design was used to evaluate OSA patients who underwent MMA > 2 years ago. The primary outcome measure was the apnea-hypopnea index (AHI). Secondary outcome measures included blood pressure (BP), sleepiness (Epworth Sleepiness Scale [ESS]), and quality of life (Functional Outcomes of Sleep Questionnaire [FOSQ]). Results: 30 adult patients (80% men, age 50.5 ± 9.6 years [mean ± SD]) participated in the study. The AHI decreased from a mean of 49 to 10.9 events/h (p < 0.0001) at the time of long-term evaluation (6.6 ± 2.8 years after MMA), with 46.7% of patients obtaining an AHI < 5 and 83.4% of patients attaining an AHI ≤ 15 events/h. The mean diastolic BP decreased from 83.7 to 79.0 mm Hg (p < 0.05). ESS decreased from a mean of 12.1 to 6.0 (p < 0.01). FOSQ increased from a mean of 12.6 to 17.3 (p < 0.05). Few long-term treatment-related adverse events occurred, which had minimal impact on quality of life (QOL). Conclusions: MMA is a clinically effective and safe long-term treatment for most patients with moderate-to-severe OSA as demonstrated by significant decreases in AHI, diastolic BP, and subjective sleepiness, with concomitant significant improvements in QOL. The results of this small cohort study suggest that MMA should be considered as the alternative treatment of choice for patients with severe OSA who cannot fully adhere to CPAP therapy.

The Japan Hypertension Evaluation with Angiotensin II Antagonist Losartan Therapy (J-HEALTH) study is a nationwide, prospective, multicentered, observational study that was designed to enroll 30,000 hypertensive Japanese patients from more than 3,000 private practitioners. It is the first large-scale observational study to assess the efficacy and safety of losartan, an angiotensin II receptor antagonist, in Japan. Patients were enrolled between June 2000 and May 2002, and followed up to June 2005. The data from 29,850 patients were used for the analysis of safety and efficacy. These patients were treated with losartan mostly at a daily dose of 25-50 mg. The mean follow-up period was 2.9 years. The patients were aged 62.4+/-12.1 years (mean+/-SD) and their mean systolic/diastolic blood pressure was 165.3+/-17.2/94.3+/-11.7 mmHg (mean+/-SD). Mean blood pressure in patients who were evaluated for efficacy decreased from 165.8/94.8 mmHg (n=26,512) at baseline to 145.5/84.4 mmHg after 3 months (n=21,269) and 138.6/80.0 mmHg after 36 months of treatment (n=13,879). Blood pressure was well controlled during the study period by losartan alone or losartan-based combination therapy. In nearly half of the patients, blood pressure was reduced to less than 140/90 mmHg during the study period. In addition to its antihypertensive effect, losartan reduced the uric acid level in patients whose baseline uric acid level was > or =7 mg/dL. Losartan also prevented acceleration of proteinuria. Adverse drug reactions occurred in 1,081 of the 29,850 patients. Long-term losartan therapy was effective and well tolerated in Japanese clinical practice.

The rapid reversal of the effects of vitamin K antagonists is often required in cases of emergency surgery and life-threatening bleeding, or during bleeding associated with high morbidity and mortality such as intracranial haemorrhage. Increasingly, four-factor prothrombin complex concentrates (PCCs) containing high and well-balanced concentrations of vitamin K-dependent coagulation factors are recommended for emergency oral anticoagulation reversal. Both the safety and efficacy of such products are currently in focus, and their administration is now expanding into the critical care setting for the treatment of life-threatening bleeding and coagulopathy resulting either perioperatively or in cases of acute trauma. After 15 yr of clinical use, findings of a pharmacovigilance report (February 1996-March 2012) relating to the four-factor PCC Beriplex P/N (CSL Behring, Marburg, Germany) were analysed and are presented here. Furthermore, a review of the literature with regard to the efficacy and safety of four-factor PCCs was performed. Since receiving marketing authorization (February 21, 1996), ~647 250 standard applications of Beriplex P/N have taken place. During this time, 21 thromboembolic events judged to be possibly related to Beriplex P/N administration have been reported, while no incidences of viral transmission or heparin-induced thrombocytopenia were documented. The low risk of thromboembolic events reported during the observation period (one in ~31 000) is in line with the incidence observed with other four-factor PCCs. In general, four-factor PCCs have proven to be well tolerated and highly effective in the rapid reversal of vitamin K antagonists.

The long-term safety of droxidopa for the treatment of symptomatic neurogenic orthostatic hypotension in patients with Parkinson disease, pure autonomic failure, multiple system atrophy, or nondiabetic autonomic neuropathy was evaluated in a phase 3, multinational, open-label study in patients who previously participated in a double-blind, placebo-controlled clinical trial of droxidopa. A total of 350 patients received droxidopa 100 to 600 mg three times daily. Mean duration of droxidopa exposure was 363 days (range, 2-1133 days). Rates of serious adverse events (AEs), cardiac-related AEs, and supine hypertension were 24%, 5%, and 5%, respectively. Most AEs, including those of a cardiovascular nature, were not attributed by investigators to droxidopa. In this large cohort of patients with neurogenic orthostatic hypotension, droxidopa was well tolerated during long-term use. Copyright © 2016 The Author. Published by Elsevier Inc.

Periodontitis represents a highly prevalent health problem, causing severe functional impairment, reduced quality of life and increased risk of systemic disorders, including respiratory, cardiovascular and osteoarticular diseases, diabetes and fertility problems. It is a typical example of a multifactorial disease, where a polymicrobial infection inducing chronic inflammation of periodontal tissues is favoured by environmental factors, life style and genetic background. Since periodontal pathogens can colonise poorly vascularised niches, antiseptics and antibiotics are typically associated with local treatments to manage the defects, with unstable outcomes especially in early-onset cases. Here, the results of a retrospective study are reported, evaluating the efficacy of a protocol (Periodontal Biological Laser-Assisted Therapy, Perioblast™) by which microbial profiling of periodontal pockets is used to determine the extent and duration of local neodymium-doped yttrium aluminium garnet (Nd:YAG) laser irradiation plus conventional treatment. The protocol was applied multicentrically on 2683 patients, and found to produce a significant and enduring improvement of all clinical and bacteriological parameters, even in aggressive cases. Microbiome sequencing of selected pockets revealed major population shifts after treatment, as well as strains potentially associated with periodontitis in the absence of known pathogens. This study, conducted for the first time on such a large series, clearly demonstrates long-term efficacy of microbiology-driven non-invasive treatment of periodontal disease.

In this work, a series of polyurea-based lambda-cyhalothrin-loaded microcapsules (MCs) with three different size distributions (average diameters of 1.35 μm, MC-S; 5.13 μm, MC-M; and 21.48 μm, MC-L) were prepared and characterized. The results indicated that MCs with a smaller particle size distribution had a faster release rate and excellent initial efficacy against pests. MC-L had a remarkably slow incipient release rate, outstanding photostability and better later-stage efficacy than that of the other tested MCs. The results clarified that the diameter distribution of MCs is the key factor in determining the release property and bioactivity of the MC formulations. Subsequently, the binary mixture MC formulations of MC(+M), MC(S+L) and MC(M+L) were obtained by mixing MC-S, MC-M or MC-L at 1:1 to establish a two-stage release system utilized for foliar application situations. Greenhouse and field experiments showed that MC(S+L) provided an optimal efficacy, and its effective duration was much longer than that of the emulsifiable concentrate (EC) group. Therefore, the release system established in this study was simple and workable for regulating the initial and long-term efficacy by adjusting the particle size distribution; in addition, this system has potential applications in other fields such as drug delivery devices.

Pressure immobilization bandages delay mortality for 8 hours after coral snake envenomation, but long-term efficacy has not been established. The objective of this study is to determine the long-term efficacy of pressure immobilization bandages after coral snake envenomation in the absence of antivenom therapy. A randomized, observational pilot study was conducted. Ten pigs (17.3-25.6 kg) were sedated, intubated for 5 hours, and injected subcutaneously with 10 mg of lyophilized Micrurus fulvius venom resuspended in water. Pigs were randomly assigned to a control group (no treatment) or a treatment group (compression bandage and splint) approximately 1 minute after envenomation. Bandage pressure was not controlled. Pigs were monitored daily for 21 days for signs of respiratory depression, decreased oxygen saturations, and paralysis. In case of respiratory depression, pigs were humanely euthanized and time to death recorded. Statistical analysis was performed with Fisher exact test, Mann-Whitney U test, and Kaplan-Meier survival curve as appropriate. Median survival time of control animals was 307 minutes compared with 1172 minutes in treated animals (P = .10). Sixty percent of pigs in the treatment group survived to 24 hours vs 0% of control pigs (P = .08). Two of the treatment pigs survived to the end point of 21 days but showed necrosis of the distal lower extremity. Long-term survival after coral snake envenomation is possible in the absence of antivenom with the use of pressure immobilization bandages. The applied pressure of the bandage is critical to allowing survival without necrosis. Future studies should be designed to accurately monitor the pressures applied. Copyright © 2014 Elsevier Inc.

The aim of this study was to assess the safety and efficacy of long-term use of 3% diquafosol ophthalmic solution (DQS), an eye drop for mucin production and water secretion, for treating dry eye disease (DED) caused by chronic graft-versus-host disease (cGVHD). We retrospectively evaluated the safety and efficacy of DQS in 10 patients with mild to moderate cGVHD-induced DED. The efficacy was assessed by (1) degree of symptoms, (2) Schirmer I test value, (3) tear film breakup time (TFBUT), and (4) fluorescein and rose bengal scores. The median duration of DQS treatment was 12.0 months (range 6-17 months). DQS was effective for relieving severe pain caused by cGVHD-related DED. Although the Schirmer I test value was enhanced only marginally, the long-term application of DQS significantly improved the corneal/conjunctival epitheliopathy and tear film stability: the fluorescein score improved from 5.9±0.6 to 1.3±1.1 points (P=1.771×10); rose bengal staining from 4.7±1.6 to 2.0±1.5 points (P=0.008); and TFBUT from 2.6±0.9 to 4.6±1.6 mm (P=0.009). Furthermore, the long-term DQS treatment caused no major adverse events. This study suggested that long-term DQS treatment is a safe and robust approach for alleviating cGVHD-related DED.

Objective To examine the long term impact of a communication skills intervention on physicians' communication self-efficacy and the relationship between reported self-efficacy and actual performance. Methods 62 hospital physicians were exposed to a 20-hour communication skills course according to the Four Habits patient-centered approach in a crossover randomized trial. Encounters with real patients before and after the intervention (mean 154 days) were videotaped, for evaluation of performance using the Four Habits Coding Scheme. Participants completed a questionnaire about communication skills self-efficacy before the course, immediately after the course, and at 3 years follow-up. Change in self-efficacy and the correlations between performance and self-efficacy at baseline and follow-up were assessed. Results Communication skills self-efficacy was not correlated to performance at baseline (r=-0.16; p=0.22). The association changed significantly (p=0.01) and was positive at follow-up (r=0.336, p=0.042). The self-efficacy increased significantly (effect size d=0.27). High performance after the course and low self-efficacy before the course were associated with larger increase in communication skills self-efficacy. Conclusion A communication skills course led to improved communication skills self-efficacy more than three years later, and introduced a positive association between communication skills self-efficacy and performance not present at baseline. Practice implications Communication skills training enhances physicians' insight in own performance. PMID:23414658

Long-term potentiation and long-term depression: a clinical perspective

Long-term potentiation and long-term depression are enduring changes in synaptic strength, induced by specific patterns of synaptic activity, that have received much attention as cellular models of information storage in the central nervous system. Work in a number of brain regions, from the spinal cord to the cerebral cortex, and in many animal species, ranging from invertebrates to humans, has demonstrated a reliable capacity for chemical synapses to undergo lasting changes in efficacy in response to a variety of induction protocols. In addition to their physiological relevance, long-term potentiation and depression may have important clinical applications. A growing insight into the molecular mechanisms underlying these processes, and technological advances in non-invasive manipulation of brain activity, now puts us at the threshold of harnessing long-term potentiation and depression and other forms of synaptic, cellular and circuit plasticity to manipulate synaptic strength in the human nervous system. Drugs may be used to erase or treat pathological synaptic states and non-invasive stimulation devices may be used to artificially induce synaptic plasticity to ameliorate conditions arising from disrupted synaptic drive. These approaches hold promise for the treatment of a variety of neurological conditions, including neuropathic pain, epilepsy, depression, amblyopia, tinnitus and stroke. PMID:21779718

Long-term treatment with glucocorticoids (GCs) plays an important role in the management of arthritis patients, although the efficacy/safety balance is unfavorable. Alternatives with less (severe) adverse effects but with good efficacy are needed. Selective GC receptor modulators (SGRMs) are designed to engage the GC receptor with dissociative characteristics: transactivation of genes, which is mainly responsible for unwanted effects, is less strong while trans-repression of genes, reducing inflammation, is maintained. It is expected that SGRMs thus have a better efficacy/safety balance than GCs. A systematic review providing an overview of the evidence in arthritis is lacking. To systematically review the current literature on efficacy and safety of oral SGRMs in comparison to GCs in arthritis. A search was performed in Medline, Embase and the Cochrane Library, from inception dates of databases until May 2017. Experimental studies involving animal arthritis models or human material of arthritis patients, as well as clinical studies in arthritis patients were included, provided they reported original data. All types of arthritis were included. Data was extracted on the SGRM studied and on the GC used as reference standard; the design or setting of the study was extracted as well as the efficacy and safety results. A total of 207 articles was retrieved of which 17 articles were eligible for our analysis. Two studies concerned randomized controlled trials (RCT), five studies were pre-clinical studies using human material, and 10 studies involved pre-clinical animal models (acute and/or chronic arthritis induced in mice or rats). PF-04171327, the only compound investigated in a clinical trial setting, had a better efficacy/safety balance compared to GCs: better clinical anti-inflammatory efficacy and similar safety. Studies assessing both efficacy and safety of SGRMs are scarce. There is limited evidence for dissociation of anti-inflammatory and metabolic effects of

Peripheral neuropathic pain (PNP) poses a significant clinical challenge. The long-term efficacy of delta-9-tetrahydrocannabinol (THC)/cannabidiol (CBD) oromucosal spray was investigated in this 38-week open-label extension study. In total, 380 patients with PNP associated with diabetes or allodynia entered this study from two parent randomised, controlled trials. Patients received THC/CBD spray for a further 38 weeks in addition to their current analgesic therapy. Neuropathic pain severity was the primary efficacy measure using a pain 0-10 numerical rating scale (NRS). Additional efficacy, safety and tolerability outcomes were also investigated. In total, 234 patients completed the study (62 %). The pain NRS showed a decrease in score over time in patients from a mean of 6.9 points (baseline in the parent studies) to a mean of 4.2 points (end of open-label follow-up). The proportion of patients who reported at least a clinically relevant 30 % improvement in pain continued to increase with time (up to 9 months); at least half of all patients reported a 30 % improvement at all time points. Improvements were observed for all secondary efficacy outcomes, including sleep quality 0-10 NRS scores, neuropathic pain scale scores, subject global impression of change and EQ-5D questionnaire scores. THC/CBD spray was well tolerated for the study duration and patients did not seek to increase their dose with time, with no new safety concerns arising from long-term use. In this previously difficult to manage patient population, THC/CBD spray was beneficial for the majority of patients with PNP associated with diabetes or allodynia.

Safety self-efficacy and safety performance: potential antecedents and the moderation effect of standardization.

Katz-Navon, Tal; Naveh, Eitan; Stern, Zvi

2007-01-01

The purpose of this paper is to suggest a new safety self-efficacy construct and to explore its antecedents and interaction with standardization to influence in-patient safety. The paper used a survey of 161 nurses using a self-administered questionnaire over a 14-day period in two large Israeli general hospitals. Nurses answered questions relating to four safety self-efficacy antecedents: enactive mastery experiences; managers as safety role models; verbal persuasion; and safety priority, that relate to the perceived level of standardization and safety self-efficacy. Confirmatory factor analysis was used to assess the scale's construct validity. Regression models were used to test hypotheses regarding the antecedents and influence of safety self-efficacy. Results indicate that: managers as safety role models; distributing safety information; and priority given to safety, contributed to safety self-efficacy. Additionally, standardization moderated the effects of safety self-efficacy and patient safety such that safety self-efficacy was positively associated with patient safety when standardization was low rather than high. Hospital managers should be aware of individual motivations as safety self-efficacy when evaluating the potential influence of standardization on patient safety. Theoretically, the study introduces a new safety self-efficacy concept, and captures its antecedents and influence on safety performance. Also, the study suggests safety self-efficacy as a boundary condition for the influence of standardization on safety performance. Implementing standardization in healthcare is problematic because not all processes can be standardized. In this case, self-efficacy plays an important role in securing patient safety. Hence, safety self-efficacy may serve as a "substitute-for-standardization," by promoting staff behaviors that affect patient safety.

The purpose of this study was to evaluate the long-term effectiveness and safety of blonanserin, a second-generation antipsychotic drug developed in Japan, in patients with first-episode schizophrenia. Twenty-three antipsychotic-naïve patients with first-episode schizophrenia were treated within an open-label, 1-year, prospective trial of blonanserin (2-24 mg/day). Clinical evaluations were conducted at baseline and 2, 6, and 12 months after the start of treatment. The main outcome measures were changes in subjective well-being and subjective quality of life, as assessed by the Subjective Well-being under Neuroleptic treatment scale Short form-Japanese version and the Schizophrenia Quality of Life Scale-Japanese version, respectively. Secondary outcome measures included the Positive and Negative Syndrome Scale, the Brief Assessment of Cognition in Schizophrenia-Japanese version, laboratory tests, bodyweight, and extrapyramidal symptoms. Fourteen patients (60.9%) remained on the study at 1 year. In the intention-to-treat analysis, significant improvements were observed in several subscales on the Subjective Well-being under Neuroleptic treatment scale Short form-Japanese version, the Schizophrenia Quality of Life Scale-Japanese version, and the Brief Assessment of Cognition in Schizophrenia-Japanese version, and in all factor scores on the Positive and Negative Syndrome Scale. Improvement in depressive symptoms with blonanserin treatment was positively correlated with improvements in subjective well-being and subjective quality of life, as well as verbal memory. No significant changes were noted for any safety measure during the 1-year study period. Blonanserin was well tolerated and effective for the treatment of first-episode schizophrenia in terms of subjective wellness, cognition, and a wide range of pathological symptoms. Further large-scale studies are warranted to confirm our findings. © 2014 The Authors. Psychiatry and Clinical Neurosciences © 2014

Seventy-four children (43 with chronic constipation, 31 with constipation and encopresis) treated with polyethylene glycol 3350 (PEG) for longer than 3 months were studied to assess long-term efficacy. The mean duration of PEG therapy was 8.4 months (range, 3-30). Weekly stool frequency, stool consistency, and symptoms associated with constipation improved significantly with PEG therapy in all 74 patients. In 31 children with encopresis, soiling ceased completely in 16 patients and frequency of soiling decreased significantly in all others. The average effective long-term dose of PEG was 0.7 g/kg/day. Long-term PEG therapy is effective for the treatment of chronic constipation with and without encopresis in children.

Eight patients with refractory lupus nephritis received rituximab after failing standard sequential therapy and were followed for 104 weeks after the infusion. One patient died secondary to a complicated pregnancy but had stable renal function. Three patients received a re-infusion of rituximab approximately 12 months apart due to a renal flare; during the second year of follow-up, those patients progressed toward ESRD. The four remaining patients demonstrated improvements in SLEDAI score, CrCl, and proteinuria with maintenance of their standard immunosuppressive therapy and did not require a re-infusion of rituximab. Although rituximab as induction therapy for refractory lupus nephritis has been shown to have a good response, its efficacy in long-term assessments demonstrates disappointing results.

Laparoscopic adjustable gastric banding (LAGB) is an option for the treatment of severe obesity. Few US studies have reported long-term outcomes. We aimed to present long-term outcomes with LAGB. Retrospective study of patients who underwent LAGB at an academic medical center in the US from 1/2005 to 2/2012. Outcomes included weight loss, complications, re-operations, and LAGB failure. 208 patients underwent LAGB. Mean BMI was 45.4 ± 6.4 kg/m 2 . Mean follow-up was 5.6 (0.5-10.7) years. Complete follow-up was available for 90% at one year (186/207), 80% at five years (136/171), and 71% at ten years (10/14). Percentage of excess weight loss at one, five, and ten years was 29.9, 30, and 16.9, respectively. Forty-eight patients (23.1%) required a reoperation. LAGB failure occurred in 118 (57%) and higher baseline BMI was the only independently associated factor (OR 1.1; 95%CI 1.0-1.1; p = 0.016). LAGB was associated with poor short and long-term weight loss outcomes and a high failure rate. With the increased safety profile and greater efficacy of other surgical techniques, LAGB utilization should be discouraged. Copyright © 2017 Elsevier Inc. All rights reserved.

Subcutaneous implantable cardioverter defibrillators (S-ICDs) are considered an alternative to conventional transvenous ICDs (TV-ICDs) in patients not requiring pacing. We searched MEDLINE and EMBASE for studies evaluating efficacy and safety outcomes in S-ICD patients. Outcomes were pooled across studies. Sixteen studies were included with 5380 participants (mean age range 33-56 years). Short-term follow-up data were available for 1670 subjects. The most common complication was pocket infection, affecting 2.7%. Other complications included delayed wound healing (0.6%) and wound discomfort (0.8%). 3.8% of S-ICDs were explanted, most commonly for pocket infection. Mortality rates in hospital (0.4%) and during follow-up (3.4% from 12 studies reporting) were low. Incidence of ventricular arrhythmia varied from 0% to 12%. Overall shock efficacy exceeded 96%. Inappropriate shocks affected 4.3% and was most commonly caused by T-wave oversensing. Although long-term randomised data are lacking, observational data suggest similar shock efficacy and short-term complication rates between the S-ICD and TV-ICD. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Concerns about the long-term safety of drug-eluting stents (DES) in saphenous vein grafts has become an area of controversy and uncertainty. In this retrospective registry, we compared the outcomes in 127 patients (143 lesions) treated with DES from April 2002 to June 2006 (DES group) with 131 patients (160 lesions) treated with bare-metal stents in the preceding 36 months (bare-metal stent group). End points analyzed were cumulative death, myocardial infarction, and target vessel revascularization at 2 years after stent implantation. The DES group was significantly (P<0.05) more complex with a greater frequency of diabetes (33.1%versus 15.3%), older grafts (11.6+/-5.3 years versus 9.6+/-5.2 years), restenotic lesions (23.8% versus 4.4%), total occlusions (7.7% versus 1.2%), and smaller grafts (3.16+/-0.66 mm versus 3.44+/-0.76 mm) treated with longer stents (34.1+/-25.1 mm versus 22.7+/-11.6 mm). At 2 years, there was no statistical difference in death (8.7% versus 7.8%), myocardial infarction (6.3% versus 9.4%), or target vessel revascularization (19.7% versus 24.2%) between DES and bare-metal stents, respectively. A propensity analysis to adjust for baseline differences suggested that there was no observed association between DES and increased mortality (hazard ratio, 0.72; 95% CI, 0.21 to 2.44; P=0.60) but possibly an association with a reduction in target vessel revascularization (hazard ratio, 0.31; 95% CI, 0.14 to 0.66; P=0.002). Despite being implanted in patients and lesions more complex than the bare-metal stent group, there was no observed association between DES implantation in saphenous vein grafts and an increase in late mortality. DES may maintain their efficacy in reducing revascularization rates in diseased saphenous vein grafts over a 2-year follow-up period.

Neovascular age-related macular degeneration (AMD) and diabetic macular edema (DME) are major causes of visual impairment in the elderly population worldwide. With the aging population, the prevalence of neovascular AMD and DME has increased substantially over the recent years. Vascular endothelial growth factor (VEGF) has been implicated as playing an important role in the pathogenesis of both neovascular AMD and DME. Since its introduction in 2006, ranibizumab, a recombinant, humanized, monoclonal antibody fragment against all isoforms of VEGF-A, has revolutionized the treatment of neovascular AMD and DME. The efficacy and safety of ranibizumab in neovascular AMD has been demonstrated in the ANCHOR and MARINA trials. Further studies including the PIER, PrONTO, and SUSTAIN trials have also evaluated the optimal dosing regimen of ranibizumab in neovascular AMD. The CATT and IVAN trials compared the safety and efficacy of ranibizumab with off-label use of bevacizumab. Studies such as SUSTAIN and HORIZON have shown that ranibizumab has a good safety profile and is well tolerated for over 4 years with very few serious ocular and systemic adverse events. For DME, Phase II RESOLVE study and Phase III RISE and RIDE studies have demonstrated superiority of ranibizumab treatment in improving vision over placebo controls. Phase II READ and Phase III RESOLVE and REVEAL studies have shown that ranibizumab is more effective both as monotherapy and in combination with laser compared with laser monotherapy. The 3-year results from the DRCRnet protocol I study found that ranibizumab with deferred laser resulted in better long-term visual outcome compared with ranibizumab with prompt laser. This review summarizes various important clinical trials on the long-term efficacy and safety of ranibizumab in the treatment of neovascular AMD and DME. The pharmacological properties of ranibizumab, its cost effectiveness, and impact on quality of life will also be discussed. PMID:23766636

Rituximab (RTX) has emerged as an attractive off-label treatment option for patients with myasthenia gravis (MG) refractory to other immune therapies. However, data on long-term outcome after RTX for MG are still scarce. Here we present the 10-year outcomes [median (range) 10.1 (6.7-11.2) years] with respect to efficacy, safety, costs of inhospital care, and impact on childbearing potential in all four MG patients treated by one of the authors with RTX. In all patients, RTX led to sustained clinical improvement and eventual tapering of other immune therapies. RTX was well tolerated, and complications were not observed. After the start of RTX, annual costs for hospital admissions were markedly reduced compared to costs in the year preceding RTX. Under close clinical observation, two patients had uncomplicated pregnancies giving birth to a healthy child. With regard to its efficacy, excellent tolerance, lack of complications, low frequency of repeat infusions and pending patent expiry in many countries, RTX appears to compare favourably with other immune therapies used for MG. Multicentre trials and registries are urgently needed to further address long-term safety issues and clarify the efficacy and role of RTX in managing MG. Copyright © 2017 Elsevier B.V.

Low-dose azathioprine with allopurinol (LDAA) has been proposed as a potent therapy in inflammatory bowel disease (IBD) with the benefit of overcoming side effects regularly associated with thiopurine monotherapy and poor responses. Concerns regarding safety remain, while a layer of complexity has been added by the trend toward treatment directed by red cell thioguanine nucleotide (TGN) profiling. We report on the clinical efficacy and safety of LDAA use in IBD undirected by metabolite profiling. Observational study of clinical practice from a single IBD center. Patient outcomes were defined clinically based on established activity scores and corticosteroid withdrawal. Red cell TGN was monitored only for suspected nonadherence. Overall, 113/164 (69%) patients with Crohn's disease and 83/136 (61%) patients with ulcerative/unclassified colitis had a clinical response by the end of follow-up (median 19 months), while 85 (52%) patients with Crohn's disease and 74 (54%) patients with ulcerative/unclassified colitis were in clinical remission. Clinical response was seen in 45/57 (79%) patients with Crohn's disease and 34/53 (64%) patients with ulcerative/unclassified colitis who were thiopurine naive, had active IBD, and received LDAA as the first line immunomodulator, while in 35 (61%) and 28 (53%), respectively, remission was achieved. LDAA was stopped in 20/300 (7%) patients because of side effects, all of which resolved on drug cessation. This is the largest cohort supporting the favorable safety profile and high efficacy of LDAA in IBD. It presents 2 advances in therapy: prescribing LDAA for thiopurine-naive patients, and bypassing TGN monitoring in favor of clinical monitoring (blood counts, etc.), which will make it more accessible for clinics without access to TGN assays.

Retinitis pigmentosa is a common genetic disease that causes retinal degeneration and blindness for which there is currently no curable treatment available. Vision preservation was observed in retinitis pigmentosa animal models after retinal stem cell transplantation. However, long-term safety studies and visual assessment have not been thoroughly tested in retinitis pigmentosa patients. In our pre-clinical study, purified human fetal-derived retinal progenitor cells (RPCs) were transplanted into the diseased retina of Royal College of Surgeons (RCS) rats, a model of retinal degeneration. Based on these results, we conducted a phase I clinical trial to establish the safety and tolerability of transplantation of RPCs in eight patients with advanced retinitis pigmentosa. Patients were studied for 24 months. After RPC transplantation in RCS rats, we observed moderate recovery of vision and maintenance of the outer nuclear layer thickness. Most importantly, we did not find tumor formation or immune rejection. In the retinis pigmentosa patients given RPC injections, we also did not observe immunological rejection or tumorigenesis when immunosuppressive agents were not administered. We observed a significant improvement in visual acuity (P < 0.05) in five patients and an increase in retinal sensitivity of pupillary responses in three of the eight patients between 2 and 6 months after the transplant, but this improvement did not appear by 12 months. Our study for the first time confirmed the long-term safety and feasibility of vision repair by stem cell therapy in patients blinded by retinitis pigmentosa.

Kalva, Sanjeeva P., E-mail: skalva@partners.org; Marentis, Theodore C.; Yeddula, Kalpana

Purpose: To assess the long-term safety and effectiveness of the OptEase inferior vena cava (IVC) filter. Materials and Methods: In this Institutional Review Board-approved, retrospective study, we reviewed data of 71 patients who received an OptEase filter at our institution from 2002 to 2007. Thirty-nine (55%) patients had symptoms of venous thromboembolism before filter placement. The indications for filter included contraindication to anticoagulation in 31 (44%) patients, prophylaxis against pulmonary embolism (PE) in 29 (41%) patients, and failure of anticoagulation in 11 (15%) patients. Procedure-related complications, such as symptomatic post-filter PE, deep venous thrombosis (DVT), IVC occlusion, and incidental imaging-evidentmore » filter-related complications, were recorded. Safety was assessed by the occurrence of filter-related complications during placement and follow-up. Effectiveness was assessed by the occurrence of post-filter PE. Results: Sixty-five (92%) filters were placed under fluoroscopy, and 6 (8%) were placed using intravascular ultrasound guidance. Seventy (99%) filters were placed successfully. Seven (10%) filters were placed in the suprarenal cava. Retrieval was attempted in 14 (20%) patients, and 12 filters were successfully retrieved. Clinical follow-up was available for 20 {+-} 21 months. Symptoms of postfilter PE and DVT occurred in 15% (n = 11) and 10% (n = 7) patients, respectively. None of these patients had computed tomography (CT)-proven PE, and only one had ultrasound-proven new DVT. One patient had symptomatic IVC occlusion. Follow-up abdominal CT in 20 patients showed thrombus in the filter in two of them. There were no instances of filter migration, filter tilt, or caval wall penetration. Conclusion: The OptEase filter appears to have an acceptable long-term safety profile. The filter was effective against PE.« less

We report long-term efficacy and cardiac safety outcomes in patients with HER2-positive early breast cancer treated with neoadjuvant pertuzumab plus trastuzumab with anthracycline-containing or anthracycline-free chemotherapy. Descriptive efficacy analyses were conducted in patients randomised to group A (cycles 1-6: trastuzumab [8 mg/kg loading dose and 6 mg/kg maintenance] plus pertuzumab [840 mg loading dose and 420 mg maintenance], plus 5-fluorouracil, epirubicin and cyclophosphamide [FEC] [cycles 1-3; 500 mg/m 2 5-fluorouracil/100 mg/m 2 epirubicin/600 mg/m 2 cyclophosphamide] then docetaxel [cycles 4-6; 75 mg/m 2 , escalated to 100 mg/m 2 if well tolerated]), B (cycles 1-3: FEC, cycles 4-6: trastuzumab plus pertuzumab plus docetaxel as mentioned previously) or C (cycles 1-6: trastuzumab plus pertuzumab plus docetaxel [75 mg/m 2 , without dose escalation], and carboplatin [AUC 6]), five years after randomisation of the last patient. This study is registered with ClinicalTrials.gov, number NCT00976989. Three-year Kaplan-Meier survival estimates for disease-free survival (DFS) were 87% (95% confidence interval: 79-95), 88% (80-96) and 90% (82-97) in groups A-C, respectively. Progression-free survival (PFS) rates were 89% (81-96), 89% (81-96) and 87% (80-95). DFS hazard ratio for total pathological complete response (tpCR) versus no tpCR was 0.27 (0.11-0.64). During post-treatment follow-up, 2/72 (2.8%), 3/75 (4.0%) and 4/76 (5.4%) patients in groups A-C had any-grade left ventricular systolic dysfunction; eight (11.1%), 12 (16.0%) and nine (11.8%) patients experienced left ventricular ejection fraction declines ≥10% from baseline to <50%. Long-term DFS and PFS were similar between groups. Patients who achieved tpCR had improved DFS. No new safety signals were identified. Copyright © 2017 Elsevier Ltd. All rights reserved.

This study was conducted with a swine model to determine the safety of long-term dietary supplementation with L-arginine-HCl or L-arginine free base. Beginning at 30 days of age, pigs were fed a corn- and soybean meal-based diet (31.5 g/kg body weight/day) supplemented with 0, 1.21, 1.81 or 2.42 % L-arginine-HCl (Experiment 1) or with 0, 1, 1.5 or 2 % L-arginine (Experiment 2). The supplemental doses of 0, 1, 1.5, and 2 % L-arginine provided pigs with 0, 315, 473, and 630 mg L-arginine/kg body weight/day, respectively, which were equivalent to 0, 286, 430, and 573 mg L-arginine/kg body weight/day, respectively, in humans. At 121 days of age (91 days after initiation of supplementation), blood samples were obtained from the jugular vein of pigs at 1 and 4 h after feeding for hematological and clinical chemistry tests. Dietary supplementation with L-arginine increased plasma concentrations of arginine, ornithine, proline, albumin and reticulocytes, while reducing plasma concentrations of ammonia, free fatty acids, triglyceride, cholesterol, and neutrophils. L-Arginine supplementation enhanced protein gain and reduced white-fat deposition in the body. Other variables in standard hematology and clinical chemistry tests, serum concentrations of insulin, growth hormone and insulin-like growth factor-I did not differ among all the groups of pigs. These results indicate that dietary supplementation with L-arginine (up to 630 mg/kg body weight/day) is safe in pigs for at least 91 days. Our findings help guide clinical studies to determine the safety of long-term oral administration of L-arginine to humans.

Sodium oxybate is licensed in Europe for the treatment of narcolepsy with cataplexy in adults. The aim of this study was to assess the efficacy and safety of sodium oxybate in clinical practice in patients with narcolepsy and cataplexy refractory to other treatments. This was a retrospective single centre study including patients with severe narcolepsy with cataplexy refractory to other treatments, who were initiated on sodium oxybate between 2009 and 2015. Patients were allowed to be on other stimulants or/and anti-cataplectic agents. Epworth sleepiness scale (ESS) and weekly cataplexy events were recorded. Side effects (SEs) were recorded at every follow-up visit. 90 patients were prescribed sodium oxybate, with a total of 3116 patient-months of drug exposure. ESS and weekly cataplexy events were significantly reduced by sodium oxybate for all patients (ΔESS = 4.3 ± 4.4 and Δcataplexy = 21.8 ± 18.5 events/week; p < 0.0001, respectively). The required maintenance dose could not be predicted based upon gender, body mass index, or clinical factors. 60% of patients were able to reduce or come off other medications. Half of the patients experienced at least one SE, and 26.6% had to stop treatment due to limiting SEs. Nausea, mood swings and enuresis were the most commonly reported SEs. SEs that led to drug discontinuation, particularly psychosis, were associated with increasing age and were observed early after the initiation of the drug. Sodium oxybate provides a good clinical efficacy and acceptable safety profile in routine clinical practice for the treatment of patients suffering from narcolepsy with cataplexy. A quarter of patients experience SEs requiring withdrawal of the drug with older patients being more vulnerable to the more serious SEs. Copyright © 2017 The Authors. Published by Elsevier B.V.

Short term efficacy of combination antiretroviral therapy (cART) in resource-constrained settings is comparable to that found in western studies. However, long term data are limited. India has the third largest HIV infected population in the world but the long-term outcome of first line therapy according to the national guidelines has not been evaluated yet. Therefore, we conducted a long-term longitudinal analysis of the efficacy of the national first-line therapy in India from an observational cohort of Indian patients in two different clinical settings. A total 323 patients who had been on ART for a median of 23 months and achieved virological suppression <100 copies/ml by their study baseline visit, were included and followed for two years. Blood samples were collected every six months for viral load and CD4 count. Drug resistance genotyping was performed when the viral load was >2000 copies/mL. Adherence and treatment interruptions (>48 h) were assessed via self-report. In the studied patients, the median duration of viral suppression was 44 months; 15.8% of patients showed viral rebound, and 2.8% viral failure. Viral rebound or failure was significantly negatively related to perfect adherence (100% adherence and no treatment interruption >48 hrs). Virological re-suppression in the subsequent visit was observed in three patients without any change in therapy despite the presence of key mutations. Our study reports for the first time, a good long-term response to the first line therapy for a median of nearly four years although a less than perfect adherence increases the risk for treatment failure and subsequent drug resistance development. The empirical findings in this study also indicate the overall success of the Indian ART program in two different settings which likely are representative of other clinics that operate under the national guidelines.

Considering the costs incurred by sickness absence and the implications for the workers' quality of life, a fast return to work (RTW) is important. Self-efficacy (SE) seems to be an important predictor of RTW for employees with mental health problems. The predictive value of return-to-work self-efficacy (RTW-SE) has not been examined in employees on long-term sickness absence due to any cause. The aim of this study is to investigate whether RTW-SE is a predictor of time to RTW in long-term sick-listed employees with all-cause sickness absence. Furthermore, the relative contribution of RTW-SE in predicting RTW will be examined compared to health-related, job-related and personal factors. In a longitudinal study, sick-listed employees who were currently on sick leave for more than 4 weeks filled out a self-report questionnaire. Demographics, health-related, personal, and job-related factors, and RTW-SE were measured. Employees were followed for 2 years to determine the duration until full RTW. Cox proportional hazards regression analyses were used to identify factors associated with time to RTW. Data were collected from 493 sick-listed employees. RTW-SE was a significant predictor of RTW. In a multivariate model, low RTW-SE, the thought of not being able to work while having symptoms (illness behaviour) and having chronic medical conditions were predictors of a longer duration until RTW. When guiding long-term sick-listed employees, it is important to focus on factors such as SE and illness behaviour, instead of just focusing on the symptoms of the sick-listed employee.

Cilostazol, a phosphodiesterase III inhibitor, is indicated to treat the symptoms of intermittent claudication and increase walking distance in patients with peripheral arterial disease (PAD). At the time of approval, the United States Food and Drug Administration required an additional long-term safety study to evaluate the effect cilostazol on mortality. A total of 1899 subjects with a clinical diagnosis of PAD and symptoms of claudication were screened for participation in a randomized, double-blinded, placebo-controlled safety study of cilostazol. The intent-to-treat (ITT) population, which was the primary analysis (n = 1435), was defined as all randomized patients who received at least one dose of study medication and included patients who were followed up >30 days after discontinuation of study drug. A total of 717 patients received cilostazol and 718 received placebo. Cilostazol was administered at a primary dose of 100 mg twice daily. The dose could be reduced to 50 mg twice daily if patients experienced an adverse event that might have been drug related. Long-term adherence to study medication was poor, with >60% of participants discontinuing therapy by 36 months. The mortality analysis therefore focused on deaths during the period on-treatment, defined as the period during which the study drug was taken plus a 30-day follow-up period after dosing. Total patient-years of exposure were 1046 on-treatment for cilostazol and 1090 for placebo. On-treatment, there were 18 deaths on cilostazol and 19 deaths on placebo for a hazard ratio of 0.99 (95% confidence interval [CI], 0.52-1.88). Cardiovascular deaths on-treatment occurred in 14 patients on cilostazol and 14 on placebo. In the full ITT population at 36 months, there were 101 deaths, 49 on cilostazol and 52 on placebo, with hazard ratio of 0.94 (95% CI, 0.64-1.39). Thus, most deaths occurred >30 days after study drug discontinuation. Serious bleeding events affected 18 patients taking cilostazol in the on

Teneligliptin is a novel oral dipeptidyl peptidase-4 inhibitor for the treatment of type 2 diabetes mellitus (T2DM). Safety and efficacy of teneligliptin have been demonstrated in clinical studies; however, data supporting its use in patients with moderate or severe renal impairment are limited. This interim analysis of a post-marketing surveillance of teneligliptin, exploRing the long-term efficacy and safety included cardiovascUlar events in patients with type 2 diaBetes treated bY teneligliptin in the real-world (RUBY), aims to verify the long-term safety and efficacy of teneligliptin in Japanese patients with T2DM and impaired renal function. For this analysis, we used the data from case report forms of the RUBY surveillance between May 2013 and June 2017. The patients were classified into G1-G5 stages of chronic kidney disease according to estimated glomerular filtration rate (eGFR) at initiation of teneligliptin treatment. Safety and efficacy were evaluated in these subgroups. Patients on dialysis were also assessed. Safety was assessed from adverse drug reactions (ADRs). Glycemic control was evaluated up to 2 years after teneligliptin initiation. A total of 11,677 patients were enrolled in the surveillance and 11,425 patient case-report forms were collected for the interim analysis. The incidence of ADRs in each subgroup was 2.98-6.98% of patients, with no differences in the ADR profile (including hypoglycemia and renal function ADRs) between subgroups. At 1 and 2 years after starting teneligliptin, the least-squares mean change in HbA1c adjusted to the baseline was - 0.68 to - 0.85% and - 0.71 to - 0.85% across the eGFR groups, respectively. Treatment with teneligliptin in patients on dialysis reduced or tended to reduce glycated albumin levels [- 2.29%, (p < 0.001) after 1 year; - 1.64%, (p = 0.064) after 2 years]. During long-term treatment, teneligliptin was generally well tolerated in patients with any stage of renal impairment from

To report interim 1-year results from a 3-year surveillance study evaluating safety, efficacy, and persistence of long-term mirabegron for overactive bladder (OAB). Patients starting treatment with mirabegron for urinary urgency, daytime frequency, and urgency incontinence associated with OAB were registered and followed up for 3 years. Data were collected on adverse drug reactions (ADR), changes in OAB symptoms, changes in Overactive Bladder Symptom Score (OABSS), and treatment discontinuations. Treatment persistence rates were calculated by Kaplan-Meier analysis. Eighty-one ADR were observed in 72/1139 patients (6.3%) through 1 year of mirabegron treatment, with the incidence highest during the first month. No significant change in residual urine volume was observed at any observation point up to 1 year of mirabegron treatment. Mirabegron was deemed "effective" in 883/1091 patients (80.9%) at 1 year/discontinuation. Total OABSS was decreased with statistical significance at 3 months, 6 months, and 1 year, or at discontinuation (P < 0.001 at each time point). Kaplan-Meier treatment persistence rates were 84.8% at 3 months, 77.6% at 6 months, and 66.0% at 1 year. Treatment persistence rates were similar for male and female patients but significantly higher for patients aged ≥65 years (67.3%; n = 908) compared with those aged <65 years (59.8%; n = 231; log-rank test: P = 0.032). Long-term OAB treatment with mirabegron was well-tolerated, with effectiveness maintained through 1 year. Mirabegron treatment persistence was higher than has been previously reported, and was greater in patients aged ≥65 years compared with those aged <65 years. © 2017 John Wiley & Sons Australia, Ltd.

Purpose To compare the short- and long-term (>1 year) efficacy and safety of radiofrequency ablation (ClosureFAST™) versus endovenous laser ablation (980 nm diode laser) for the treatment of superficial venous insufficiency of the great saphenous vein. Materials and methods Two hundred patients with superficial venous insufficiency of the great saphenous vein were randomized to receive either radiofrequency ablation or endovenous laser ablation (and simultaneous adjunctive therapies for surface varicosities when appropriate). Post-treatment sonographic and clinical assessment was conducted at one week, six weeks, and six months for closure, complications, and patient satisfaction. Clinical assessment of each patient was conducted at one year and then at yearly intervals for patient satisfaction. Results Post-procedure pain ( p < 0.0001) and objective post-procedure bruising ( p = 0.0114) were significantly lower in the radiofrequency ablation group. Improvements in venous clinical severity score were noted through six months in both groups (endovenous laser ablation 6.6 to 1; radiofrequency ablation 6.2 to 1) with no significant difference in venous clinical severity score ( p = 0.4066) or measured adverse effects; 89 endovenous laser ablation and 87 radiofrequency patients were interviewed at least 12 months out with a mean long-term follow-up of 44 and 42 months ( p = 0.1096), respectively. There were four treatment failures in each group, and every case was correctable with further treatment. Overall, there were no significant differences with regard to patient satisfaction between radiofrequency ablation and endovenous laser ablation ( p = 0.3009). There were no cases of deep venous thrombosis in either group at any time during this study. Conclusions Radiofrequency ablation and endovenous laser ablation are highly effective and safe from both anatomic and clinical standpoints over a multi-year period and neither modality achieved

Even in the absence of evidence on its long-term efficacy and safety, a number of patients with venous thromboembolism (VTE) receive long-term therapy with fondaparinux alone in everyday practice. We used the Registro Informatizado de Enfermedad Tromboembólica (RIETE) registry to compare the rate of VTE recurrences and major bleeding at 10 and 90 days in patients with and without cancer. For long-term therapy, fondaparinux was compared with vitamin K antagonists (VKA) in patients without cancer and with low-molecular-weight heparin (LMWH) in those with cancer. Of 47,378 patients recruited, 46,513 were initially treated with heparin, 865 with fondaparinux. Then, 263 patients (78 with cancer) were treated for at least 3 months with fondaparinux. After propensity-score matching, there were no differences between patients receiving initial therapy with heparin or fondaparinux. Among patients with cancer, there were no differences between fondaparinux and LMWH. Among patients without cancer, the long-term use of fondaparinux was associated with an increased risk of major bleeding (3.24 % vs. 0.95 %, p<0.05). An unexpected high rate of major bleeding was observed in non-cancer patients treated with long-term fondaparinux. Our small sample does not allow to derive relevant conclusions on the use of fondaparinux in cancer patients. Copyright © 2014 Elsevier Ltd. All rights reserved.

In the 4-week GAIN clinical trial, adalimumab was efficacious in inducing remission in patients with moderate to severe Crohn's disease (CD) who had prior loss of response/intolerance to infliximab. The efficacy and safety of adalimumab in these patients are reported here up to 96 weeks or for 3 years, respectively, in ADHERE open-label extension study. Patients who completed GAIN could enrol in ADHERE and receive open-label adalimumab 40 mg every other week. Efficacy variables included clinical response (Crohn's Disease Activity Index [CDAI] decrease from baseline ≥70/≥100 points [CR-70/CR-100]) and remission (CDAI<150), steroid discontinuation and fistula remission (absence of drainage). Data were reported using hybrid non-responder imputation (hNRI), last observation carried forward and as-observed analysis. Subgroup analyses were performed by randomised group in GAIN and by Week 4 efficacy in GAIN. Safety was also assessed. A total of 310 patients from GAIN enrolled in ADHERE. CR-70, CR-100 and remission rates at Week 96 were 39.0%, 35.5% and 26.5% (hNRI), respectively. Of the patients with CR-70 response or remission at Week 4 of GAIN, 45.5% and 44.4% (hNRI), respectively, maintained effect at Week 96. Steroid discontinuation and steroid-free remission rates increased from Week 12 to 96 in patients using corticosteroids at GAIN baseline. Long-term adalimumab maintenance therapy led to sustained clinical remission and response, and steroid discontinuation in a considerable proportion of patients with CD previously treated with infliximab. No new safety signals were observed in this patient population.

Physical activity has been effective in enhancing quality of life (QOL) of older adults over relatively short periods of time. However, little is known about the long-term effects of physical activity and even less about the possible mediators of this relationship. We examined the mediating effects of psychological variables on the relationship between physical activity and global QOL (satisfaction with life) in older adults over a 4-year period. Participants (N = 174, M age = 66.7 years) completed a battery of psychosocial measures at 1 and 5 years following enrollment in a 6-month randomized controlled exercise trial. Panel analysis conducted within a covariance modeling framework indicated that physical activity was related to self-efficacy, physical self-esteem, and positive affect at 1 year, and in turn, greater levels of self-efficacy and positive affect were associated with higher levels of QOL. Analyses indicated that changes in physical activity over the 4-year period were related to increases in physical self-esteem and positive affect, but only positive affect directly influenced improvements in QOL. The findings lend support to the position that physical activity effects on QOL are in part mediated by intermediate psychological outcomes and that physical activity can have long-term effects on well-being.

Endovascular treatment of coarctation of aorta (CoA) by self-expandable Nitinol stents is one of the recognized treatment methods and may be an alternative to surgery or balloon-expandable stent implantation for CoA but there is little information about midterm to long term results of self-expandable stents. Sixty-two patients with CoA (40 men), with a mean age of 30.7 ± 11 years, (range 17-63 years) underwent stent implantation with Optimed self-expandable Nitinol stents between 2005 and 2014. Successful outcome was defined as peak systolic pressure gradient ≤20 mmHg after stent implantation. The patients were followed-up clinically and by echocardiography and in patients, in whom there was suspicion of recoarctation, CT angiography or recatheterization was performed. 65 stents were successfully implanted in all 62 patients. Peak systolic pressure gradient decreased from mean 62.4 ± 18 mmHg (range 35-100 mmHg) to mean 2.8 ± 5 mmHg (range 0-15 mmHg; P < 0.001). Stent displacement occurred in 3 patients during the procedure. These were managed successfully by an overlapping second stent. None of the patients had major complications such as aortic dissection, rupture, or vascular access problems. In follow up, only three patients had recoarctation, and two of these were managed successfully by balloon redilation or further stenting 16 and 18 months after the first procedure and one patient refused reintervention. There were two deaths, unrelated to the procedure, 12 and 78 months after the initial intervention. Follow-up of a mean of 45.5 ± 17 months (range 12-105 months) demonstrated no evidence of aneurysm formation or stent fracture. Self-expandable nitinol stents for the treatment of native and recurrent CoA is safe and has good efficacy with acceptable midterm to long-term outcome. © 2017 Wiley Periodicals, Inc.

Objective This study examined whether changes in self-efficacy explain the effects of a mailed print intervention on long-term dietary practices of breast and prostate cancer survivors. The relationship between change in self-efficacy and long-term physical activity (PA) also was examined. Methods Breast and prostate cancer survivors (N=543) from 39 U.S. states and two Canadian provinces participated in the FRESH START intervention trial. Participants were randomly assigned to receive a 10-month program of mailed print materials on diet and PA available in the public domain or a 10-month program of tailored materials designed to increase fruit and vegetable (F&V) intake, decrease fat intake, and/or increase PA. Changes in self-efficacy for F&V intake and fat restriction were analyzed as potential mediators of the intervention’s effects on diet at 2-year follow-up. Because we previously found that change in self-efficacy for PA did not vary by group assignment, the relationship between change in self-efficacy and PA at 2-year follow-up was examined across study conditions. Results Results suggest that change in self-efficacy for fat restriction partially explained the intervention’s effect on fat intake (mean indirect effect=-.28), and change in self-efficacy for F&V consumption partially explained the intervention’s effect on daily F&V intake (mean indirect effect=.11). Change in self-efficacy for fat restriction partially accounted for the intervention’s impact on overall diet quality among men only (mean indirect effect=.60). Finally, change in self-efficacy for PA predicted PA at 2-year follow-up. Conclusions Findings suggest that self-efficacy may influence long-term maintenance of healthy lifestyle practices among cancer survivors. PMID:22544562

Quantitative information is scarce in current obesity medication guidelines, and they do not clearly reflect the differences in the efficacy characteristics among various drugs. This study quantitatively assessed the efficacy characteristics of five FDA-approved long-term weight loss drugs. Potentially eligible studies were obtained from public databases. Using the differences in the weight change from baseline between the drug group and the corresponding placebo group as the major indicator of efficacy, a time-effect model was established, and crucial pharmacodynamic parameters, such as the maximal efficacy, drug onset time and rate of body weight regain after the maximal efficacy point, were used to reflect the differences in efficacy among the five drugs. Finally, 50 reports (involving 43,443 participants) were included. After deducting the placebo effects, the maximal efficacies (95% CI) of orlistat (120 mg), lorcaserin, naltrexone-bupropion, phentermine-topiramate (PT, 7.5/46 mg) and liraglutide were -2.94 (-5.82, -1.27), -3.06 (-4.39, -1.71), -6.15 (-9.78, -3.25), -7.45 (-9.76, -3.88) and -5.50 (-10.62, -2.97) kg at weeks 60, 54, 67, 59 and 65 respectively, and their rates of body weight regain were 0.51, 0.48, 0.91, 1.27and 0.43 kg per year respectively. The 1-year dropout rates of orlistat, lorcaserin, naltrexone-bupropion, PT and liraglutide were 29.0, 40.9, 49.1, 34.9 and 24.3% respectively. In addition, a significant dose-effect correlation was observed for orlistat and PT. This study provides valid quantitative information for medication guidelines. © 2017 World Obesity Federation.

Purpose We assessed the long-term efficacy and safety of human retinal progenitor cells (hRPC) using established rodent models. Methods Efficacy of hRPC was tested initially in Royal College of Surgeons (RCS) dystrophic rats immunosuppressed with cyclosporine/dexamethasone. Due to adverse effects of dexamethasone, this drug was omitted from a subsequent dose-ranging study, where different hRPC doses were tested for their ability to preserve visual function (measured by optokinetic head tracking) and retinal structure in RCS rats at 3 to 6 months after grafting. Safety of hRPC was assessed by subretinal transplantation into wild type (WT) rats and NIH-III nude mice, with analysis at 3 to 6 and 9 months after grafting, respectively. Results The optimal dose of hRPC for preserving visual function/retinal structure in dystrophic rats was 50,000 to 100,000 cells. Human retinal progenitor cells integrated/survived in dystrophic and WT rat retina up to 6 months after grafting and expressed nestin, vimentin, GFAP, and βIII tubulin. Vision and retinal structure remained normal in WT rats injected with hRPC and there was no evidence of tumors. A comparison between dexamethasone-treated and untreated dystrophic rats at 3 months after grafting revealed an unexpected reduction in the baseline visual acuity of dexamethasone-treated animals. Conclusions Human retinal progenitor cells appear safe and efficacious in the preclinical models used here. Translational Relevance Human retinal progenitor cells could be deployed during early stages of retinal degeneration or in regions of intact retina, without adverse effects on visual function. The ability of dexamethasone to reduce baseline visual acuity in RCS dystrophic rats has important implications for the interpretation of preclinical and clinical cell transplant studies.

Longevinex® (L/RV) is a low dose hormetic over-the-counter (OTC) oral resveratrol (RV) based matrix of red wine solids, vitamin D3 and inositol hexaphosphate (IP6) with established bioavailability, safety, and short-term efficacy against the earliest signs of human atherosclerosis, murine cardiac reperfusion injury, clinical retinal neovascularization, and stem cell survival. We previously reported our short-term findings for dry and wet age-related macular degeneration (AMD) patients. Today we report long term (two to three year) clinical efficacy. We treated three patients including a patient with an AMD treatment resistant variant (polypoidal retinal vasculature disease). We evaluated two clinical measures of ocular structure (fundus autofluorescent imaging and spectral domain optical coherence extended depth choroidal imaging) and qualitatively appraised changes in macular pigment volume. We further evaluated three clinical measures of visual function (Snellen visual acuity, contrast sensitivity, and glare recovery to a cone photo-stress stimulus). We observed broad bilateral improvements in ocular structure and function over a long time period, opposite to what might be expected due to aging and the natural progression of the patient's pathophysiology. No side effects were observed. These three cases demonstrate that application of epigenetics has long-term efficacy against AMD retinal disease, when the retinal specialist has exhausted other therapeutic modalities.

Riociguat is a soluble guanylate cyclase stimulator approved for the treatment of inoperable and persistent/recurrent chronic thromboembolic pulmonary hypertension (CTEPH). In the 16-week CHEST-1 study, riociguat showed a favourable benefit-risk profile and improved several clinically relevant end-points in patients with CTEPH. The CHEST-2 open-label extension evaluated the long-term safety and efficacy of riociguat. Eligible patients from CHEST-1 received riociguat individually adjusted up to a maximum dose of 2.5 mg three times daily. The primary objective was the safety and tolerability of riociguat; exploratory efficacy end-points included 6-min walking distance (6MWD) and World Health Organization (WHO) functional class (FC). Overall, 237 patients entered CHEST-2 and 211 (89%) were ongoing at this interim analysis (March 2013). The safety profile of riociguat in CHEST-2 was similar to CHEST-1, with no new safety signals. Improvements in 6MWD and WHO FC observed in CHEST-1 persisted for up to 1 year in CHEST-2. In the observed population at 1 year, mean±sd 6MWD had changed by +51±62 m (n=172) versus CHEST-1 baseline (n=237), and WHO FC had improved/stabilised/worsened in 47/50/3% of patients (n=176) versus CHEST-1 baseline (n=236). Long-term riociguat had a favourable benefit-risk profile and apparently showed sustained benefits in exercise and functional capacity for up to 1 year. Copyright ©ERS 2015.

Treatment with long-acting injectable (LAI) antipsychotic medication is an important element of relapse prevention in schizophrenia. Recently, the intramuscular once-monthly formulation of aripiprazole received marketing approval in Europe and the United States for schizophrenia. This study aimed to compare aripiprazole once-monthly with other LAI antipsychotics in terms of efficacy, tolerability, and safety. A systematic literature review was conducted to identify relevant double-blind randomized clinical trials of LAIs conducted in the maintenance treatment of schizophrenia. MEDLINE, MEDLINE In-Process, Embase, the Cochrane Library, PsycINFO, conference proceedings, clinical trial registries, and the reference lists of key review articles were searched. The literature search covered studies dating from January 2002 to May 2013. Studies were required to have ≥24 weeks of follow-up. Patients had to be stable at randomization. Studies were not eligible for inclusion if efficacy of acute and maintenance phase treatment was not reported separately. Six trials were identified (0.5% of initially identified studies), allowing comparisons of aripiprazole once-monthly, risperidone LAI, paliperidone palmitate, olanzapine pamoate, haloperidol depot, and placebo. Data extracted included study details, study duration, the total number of patients in each treatment arm, efficacy, tolerability, and safety outcomes. The efficacy outcome contained the number of patients that experienced a relapse, tolerability outcomes included the number of patients that discontinued treatment due to treatment-related adverse events (AEs), and that discontinued treatment due to reasons other than AEs (e.g., loss to follow-up). Safety outcomes included the incidence of clinically relevant weight gain and extrapyramidal symptoms. Data were analyzed by applying a mixed treatment comparison competing risks model (efficacy) and using binary models (safety). There was no statistically significant

The paper represents a systematic review on the efficacy, tolerability and safety of paliperidone, an antipsychotic drug recently approved in Italy for the treatment of schizophrenia and of schizoaffective disorder. A comprehensive PubMed search using the term "paliperidone" was performed from January 1980 to February 2011. Papers reporting data on efficacy in the treatment of schizophrenia and of schizoaffective disorder were included, also if published as abstracts and all retrieved articles were manually searched for other references of interest. Paliperidone was found to be effective in short and long-term treatment of schizophrenia, as well as in the treatment of schizoaffective disorder. For both disorders, paliperidone showed to be effective in improving psychotic and affective symptoms. In the studies analyzed it was well tolerated and the most frequent reported adverse events were mild extrapyramidal symptoms and an increase in serum prolactin levels. Paliperidone has been shown to be an effective and safe medication for the treatment of schizophrenia and schizoaffective disorder. Further controlled clinical trials are needed to confirm this clinical profile in the long-term treatment, as well as for specific conditions such as schizophrenic patients with medical comorbidities.

In an earlier study, we found that cognitive-behavioral therapy (CBT) delivered by general practitioners (GPs) for fatigue among employees on sick leave was not effective after 12 months. In this study we aim to assess the long-term efficacy of CBT by GPs for fatigue. It was hypothesized that the intervention could prevent deterioration as well as relapse of fatigue complaints and relapse into absenteeism in the long term. Patients who participated in the original randomized controlled trial were followed up 4 years later. Fatigue and absenteeism were the main outcomes. Fatigue and absenteeism were high in the intervention and control groups at the 4-year follow-up. There was no significant difference between the intervention group and the control group on fatigue and absenteeism. The intervention group however tended toward less-favorable outcomes as compared with the control group. Like that of chronic fatigue syndrome, the prognosis of less-advanced fatigue is rather poor. CBT delivered by GPs is not effective in the long term.

To determine the short-term and long-term treatment-effects of botulinum toxin type A in simple motor tics, we analyzed 15 consecutive patients (18 tics) with simple motor tics that were treated every 3 months with injections of BTX-A. Efficacy (rated on a 4-level scale) and duration of effect of the first 2 and last 2 (if treated 5 times or more) treatments were recorded, as well as latency of response, changes of premonitory urges (PMUs) and possible side effects. Total number of treatments for each tic varied from 2 to 50 (mean 11, median 6). In 16 of 18 tics (89%) short-term efficacy was reported successful (good or moderate). Long-term efficacy was reported in 12 tics of which 11 showed similar or even increased beneficial effects. Premonitory urge (PMU) was reported in 8 patients (53%). PMU, if present, lessened or disappeared after treatment with BTX-A. A permanent remission of the treated tic was seen in 3 patients with a maximum follow-up of 10 years. BTX-A appears a safe and effective treatment for simple motor tics and retains its efficacy after long-term treatment. BTX may also induce permanent remission of the treated tics and effects of BTX are not restricted to merely motor behaviour.

Poor adherence to regular exercise is a documented challenge among people with heart disease. Identifying key determinants of exercise adherence and distinguishing between the processes driving short- and long-term adherence to regular exercise is a valuable endeavor. The purpose of the present study was to test a model of exercise behavior change, which incorporates motivational orientations and self-efficacy for exercise behavior, in the prediction of short- and long-term exercise adherence. Male and female patients (N = 801) hospitalized for coronary heart disease were recruited from 3 tertiary care cardiac centers and followed for a period of 1 year after hospital discharge. A prospective, longitudinal design was used to examine the roles of motivation and self-efficacy (measured at recruitment and at 2 and 6 months after discharge) in the prediction of exercise behavior at 6 and 12 months. Baseline measures of exercise and clinical and demographic covariates were included in the analyses. Structural equation modeling showed that both autonomous motivation and self-efficacy were important determinants of short-term (6-month) exercise behavior regulation, but that only autonomous motivation remained a significant predictor of long-term (12-month) exercise behavior. Self-efficacy partially mediated the relationship between motivation for exercise and 6-month exercise behavior. This research confirmed the roles of autonomous motivation and self-efficacy in the health behavior change process and emphasized the key function of autonomous motivation in exercise maintenance. Theoretical and cardiac rehabilitation program applications of this research are discussed. PsycINFO Database Record (c) 2014 APA, all rights reserved.

To assess the efficacy and safety of iris-fixated phakic intraocular lens (pIOL) implantation to correct myopia in eyes with previous retinal detachment (RD) surgery. Department of Ophthalmology, Soonchunhyang University College of Medicine, Seoul, South Korea. Retrospective case series. Patients having pIOL implantation in both eyes were enrolled. Eyes that had scleral buckling or encircling (RD group) and healthy fellow eyes (non-RD group) were evaluated over a 6-year follow-up. The corrected distance visual acuity (CDVA), endothelial cell density (ECD), intraoperative complications, and long-term complications were safety outcomes. Uncorrected distance visual acuity (UDVA), predictability, and stability of refraction were efficacy outcomes. The study comprised 34 eyes (17 patients). The mean postoperative CDVA and ECD were not significantly different between groups, and no patient lost CDVA. The rate of transient intraocular pressure spike was significantly higher in the RD group (P=.043). After 3 years and 6 years, the mean postoperative UDVA was 0.06 logMAR ± 0.09 (SD) and 0.08 ± 0.10 logMAR, respectively, in the RD group and 0.04 ± 0.08 logMAR and 0.04 ± 0.09 logMAR, respectively, in the non-RD group (P=.518 and P=.478, respectively). The rate of eyes within ±0.50 diopter of the desired refraction and the postoperative refraction was not significantly different between groups. No eye had vitreoretinal changes requiring secondary surgical intervention. Iris-fixated pIOL implantation corrected the myopic refractive error in patients who had scleral buckling or encircling surgery for RD with a high degree of efficacy, safety, and long-term stability.

Sleep-disordered breathing (SDB) and Cheyne-Stokes respiration (CSR) are associated with shorter survival in patients with heart failure. A novel treatment method for this patient group is unilateral phrenic nerve stimulation by the remedē® system (Respicardia Inc., Minnetonka, MN, USA), a transvenously implantable neurostimulation device, which has recently been studied in a large randomized, controlled trial. Previous literature has shown efficacy and safety of the treatment with this first-generation device, but hardly any data are available on long-term clinical parameters, the remedē® device's battery lifetime, device exchangeability, lead position stability, surgical accessibility, and manageability. We performed remedē® device replacements in consecutive patients for battery depletion, and documented clinical parameters, longevity, operation procedure, complications, and difficulties. All patients were on neurostimulation treatment by phrenic nerve neurostimulation when device replacement became necessary. Apnea-hypopnea index (from 45 ± 4/h to 9 ± 4/h), oxygen-desaturation index (from 35 ± 7/h to 7 ± 6/h), and time spent with oxygen saturation of <90% (T < 90% from 5 ± 7% to 0 ± 0%) were improved and improvements remained constant throughout the 4-year follow-up. Mean battery life was 4.2 ± 0.2 years and mean replacement procedure time was 25 ± 5.1 minutes. Apart from conventional X-ray documentation of stable lead positions in a long-term setting, no radiation or contrast dye usage was needed and no major complications occurred. In addition, clinical exercise capacity and sleepiness symptoms improved. Novel remedē® device shows sustained therapy efficacy and safety in terms of stable lead positions over 4 years. Long-term phrenic nerve neurostimulation therapy for central SDB/CSR appears feasible in a clinical routine setting. © 2017 Wiley Periodicals, Inc.

Although the safety of topical nasal steroids is well established for nasal spray forms, data regarding the safety of steroid irrigations is limited. We studied the effect of long-term budesonide nasal irrigations (>6 months) on hypothalamic-pituitary-adrenal axis (HPAA) function and intraocular pressure (IOP) in patients post-endoscopic sinus surgery. This was retrospective case series. Adrenal function was assessed by using the high-dose cosyntropin stimulation test. A total of 48 patients were assessed, with a mean duration of budesonide irrigations of 22 months. Stimulated cortisol levels were abnormally low in 11 patients (23%). None reported to have symptoms of adrenal suppression. Three of 4 patients who repeated the study being off budesonide for at least 1 month returned to near normal levels. Logistic regression analysis revealed that concomitant use of both nasal steroid sprays and pulmonary steroid inhalers was significantly associated with HPAA suppression (p = 0.024). Patients with low stimulated cortisol levels were able to continue budesonide irrigations under the supervision of an endocrinologist without frank clinical manifestations of adrenal insufficiency. IOP was within normal limits in all patients. Long-term use of budesonide nasal irrigations is generally safe, but asymptomatic HPAA suppression may occur in selected patients. Concomitant use of both nasal steroid sprays and pulmonary steroid inhalers while using daily budesonide nasal irrigations is associated with an increased risk. Rhinologists should be alerted to the potential risks of long-term use of budesonide nasal irrigations, and monitoring for HPAA suppression may be warranted in patients receiving long-term budesonide irrigation therapy. © 2016 ARS-AAOA, LLC.

Bilastine is a novel second-generation antihistamine. This open-label, single-arm, phase III study evaluated the safety and efficacy of long-term treatment with bilastine in Japanese patients with seasonal (SAR) or perennial allergic rhinitis (PAR). Patients with SAR or PAR who met the registration criteria and did not violate the exclusion criteria received bilastine (20mg, once daily) for 12 weeks (treatment period). Patients with PAR who met the transition criteria could elect to continue the bilastine treatment for an additional 40 weeks (continuous treatment period: a total of 52 weeks). Safety and tolerability were the primary outcomes, and the main secondary endpoint was to evaluate changes in efficacy variables from baseline measurements. Fifty-eight patients with SAR and 64 patients with PAR received bilastine (20mg/day) for 12 weeks. Fifty-five patients with PAR transitioned to the continuous treatment period. Adverse events (AEs) were reported by 17.2% of patients with SAR and by 31.3% of patients with PAR, and adverse drug reactions (ADRs) were reported by 6.3% of patients with PAR but by no patients with SAR during the 12-week treatment period. All of the ADRs were mild in severity. During the 52-week treatment period, AEs and ADRs were reported by 73.4% and 6.3% of patients with PAR, respectively. All of the ADRs occurred during the 12-week treatment period, and none during the continuous treatment period. The AEs were categorized using the System Organ Class of nervous system disorders; 4.7% of patients reported headache, but none reported somnolence. One serious AE was reported, but it was considered to be unrelated to the bilastine treatment. There were no deaths, and no patients withdrew from the study because of AEs. In patients with SAR, bilastine significantly decreased the total nasal symptom score (TNSS), total ocular symptom score (TOSS), and total symptom score (TSS) relative to baseline. Prolonged treatment with bilastine resulted in the

Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). We assessed tofacitinib efficacy and safety in the Latin American (LA) subpopulation of global Phase 3 and long-term extension (LTE) studies. Data from LA patients with RA and inadequate response to disease-modifying antirheumatic drugs (DMARDs) were pooled across five Phase 3 studies. Phase 3 patients received tofacitinib 5 or 10mg twice daily (BID), adalimumab or placebo; patients in the single LTE study received tofacitinib 5 or 10mg BID; treatments were administered alone or with conventional synthetic DMARDs. Efficacy was reported up to 12 months (Phase 3) and 36 months (LTE) by American College of Rheumatology (ACR) 20/50/70 response rates, Disease Activity Score (DAS)28-4(erythrocyte sedimentation rate [ESR]) and Health Assessment Questionnaire-Disability Index (HAQ-DI). Incidence rates (IRs; patients with event/100 patient-years) of adverse events (AEs) of special interest were reported. The Phase 3 studies randomized 496 LA patients; the LTE study enrolled 756 LA patients from Phase 2 and Phase 3. In the Phase 3 studies, patients who received tofacitinib 5 and 10mg BID showed improvements vs placebo at Month 3 in ACR20 (68.9% and 75.7% vs 35.6%), ACR50 (45.8% and 49.7% vs 20.7%) and ACR70 (17.5% and 23.1% vs 6.9%) responses, mean change from baseline in HAQ-DI (-0.6 and -0.8 vs -0.3) and DAS28-4(ESR) score (-2.3 and -2.4 vs -1.4). The improvements were sustained up to Month 36 in the LTE study. In the Phase 3 studies, IRs with tofacitinib 5 and 10mg BID and placebo were 7.99, 6.57 and 9.84, respectively, for SAEs, and 3.87, 5.28 and 3.26 for discontinuation due to AEs. IRs of AEs of special interest in tofacitinib-treated LA patients were similar to the global population. In Phase 3 and LTE studies in LA patients with RA, tofacitinib demonstrated efficacy up to 36 months with a manageable safety profile up to 60 months, consistent with the overall tofacitinib

Conventional approaches for benzodiazepine tapering have their limitations. Anecdotal studies have shown that acupuncture is a potential treatment for facilitating successful benzodiazepine tapering. As of today, there was no randomized controlled trial examining its efficacy and safety. The purpose of the study is to evaluate the efficacy of using electroacupuncture as an adjunct treatment to gradual tapering of benzodiazepine doses in complete benzodiazepine cessation in long-term benzodiazepine users. The study protocol of a randomized, assessor- and subject-blinded, controlled trial is presented. One hundred and forty-four patients with histories of using benzodiazepines in ≥50% of days for more than 3 months will be randomly assigned in a 1:1 ratio to receive either electroacupuncture or placebo electroacupuncture combined with gradual benzodiazepine tapering schedule. Both experimental and placebo treatments will be delivered twice per week for 4 weeks. Major assessments will be conducted at baseline, week 6 and week 16 post-randomization. Primary outcome is the cessation rate of benzodiazepine use. Secondary outcomes include the percentage change in the doses of benzodiazepine usage and the severity of withdrawal symptoms experienced based on the Benzodiazepine Withdrawal Symptom Questionnaire, insomnia as measured by the Insomnia Severity Index, and anxiety and depressive symptoms as evaluated by the Hospital Anxiety and Depression Scale. Adverse events will also be measured at each study visit. Results of this study will provide high quality evidence of the efficacy and safety of electroacupuncture as an adjunct treatment for benzodiazepine tapering in long-term users.

Aim The aim of this study was to assess the long‐term efficacy and safety of canagliflozin as add‐on therapy in Japanese patients with type 2 diabetes mellitus who had inadequate glycaemic control with insulin. Materials and methods The study comprised a 16‐week, double‐blind period in which patients were randomized to either placebo (P; N = 70) or canagliflozin (100 mg, CAN; N = 76), followed by a 36‐week open‐label period in which all patients received canagliflozin. The efficacy endpoints included the change in HbA1c from baseline to end of treatment. The safety endpoints were adverse events, hypoglycaemic events, and laboratory test values. Results The changes from baseline (mean ± standard deviation, last observation carried forward) in the P/CAN and CAN/CAN groups, respectively, were −1.09% ± 0.85% and −0.88% ± 0.86% for HbA1c, −1.40% ± 2.54% and −2.14% ± 2.75% for body weight, and 7.84% ± 14.37% and 8.91% ± 10.80% for HOMA2‐%B (all, P < .001). Adverse events occurred in 85.1% of the P/CAN group and 92.0% of the CAN/CAN group. Hypoglycaemic events occurred in 43.3% and 54.7%, respectively. All hypoglycaemic events were mild in severity and insulin dose reduction decreased the incidence rate of hypoglycaemic events. Post‐hoc ordinal logistic modelling/logistic modelling showed that lower serum C‐peptide at Week 0 was a risk factor for hypoglycaemia in both the P and CAN groups in the double‐blind period as well as in the canagliflozin all‐treatment period. Conclusions This study demonstrates the long‐term efficacy and safety of canagliflozin combined with insulin in Japanese patients. PMID:29110384

Safety and efficacy of quetiapine in bipolar depression.

To review the clinical data investigating the efficacy and safety of quetiapine in bipolar depression. Searches of MEDLINE and PubMed (1977-July 2009) were conducted using the key words quetiapine and bipolar depression. The references of literature found were cross-referenced. The pharmaceutical company that produces quetiapine was contacted to obtain the posters for the EMBOLDEN I and EMBOLDEN II trials. Only double-blind, placebo-controlled trials were included for review, as well as any subanalyses of the literature that matched this criterion. There was a total of 5 double-blind, placebo-controlled trials and 5 subanalyses reviewed. The results of these data demonstrated quetiapine's efficacy in the treatment of depressive phases of bipolar disorder, including statistically significant improvement in the Montgomery-Asberg Depression Rating Scale (MADRS). In the trials reviewed in this article, the change in MADRS scores ranged from -15.4 to -16.94 within the quetiapine groups, and from -10.26 to -11.93 in the placebo groups. There were also statistically significant improvements in the Hamilton Anxiety Rating Scale, the Short Form of the Quality of Life Enjoyment and Satisfaction Questionnaire, the Pittsburgh Sleep Quality Index, and the Sheehan Disability Scale. All of these trials had a duration of 8 weeks and therefore cannot be applied to the long-term use of quetiapine in bipolar depression. The most common adverse events were sedation, somnolence, and dry mouth. The overall dropout rates for the trials reviewed ranged from 24% to 47%. Based on the literature reviewed here, quetiapine appears to be a safe and efficacious short-term treatment option for bipolar depression. Patients with bipolar type I showed greater improvement on the MADRS than those with bipolar type II. Patients with a rapid-cycling disease course showed an improvement in depressive symptoms, regardless of bipolar type.

Long-term safety in living kidney donors for paediatric transplantation. Single-centre prospective study.

Martin Benlloch, J; Román Ortiz, E; Mendizabal Oteiza, S

There is enough evidence concerning the short-term safety of living donors after kidney transplantation. However, long-term complications continue to be studied, with a particular interest in young donors. Previous studies have been conducted in older donors for adult renal patients. We present a study of long-term complications in kidney donors for our paediatric population. We carried out a long-term donor study for the 54 living kidney-donor transplantations performed at our department from 1979 to June 2014. We monitored the glomerular filtration rate (GFR) on the basis of 24-hour urine creatinine clearance, 24-hour proteinuria and the development of arterial hypertension in the 48 donors who were followed up for more than one year. Only the 39 patients who were exclusively followed up by our department have been included in the results analysis. GFR through creatinine clearance was stable after an initial decrease. No proteinuria was observed in any of the cases. One patient developed chronic kidney disease (CKD), which resulted in a cumulative incidence of 2%. GFR below 60mL/min/1.73 m 2 was not reported in any other patients. Arterial hypertension was diagnosed in 25% of donors, 90% of which were treated with antihypertensives. Risk of CKD and hypertension in living kidney donors for paediatric recipients, who are carefully monitored throughout their evolution, is similar to that of the general population. Therefore, this technique appears to be safe in both the short and long term. Copyright © 2016 Sociedad Española de Nefrología. Published by Elsevier España, S.L.U. All rights reserved.

Vedolizumab is the latest FDA-approved anti-integrin therapy for treatment of moderate-to-severe inflammatory bowel disease (IBD). The safety and efficacy of vedolizumab have been studied in short-term clinical trials. This paper reviews the safety profile of vedolizumab compared with other biologics. It also highlights the mechanism of action of the medication. We discuss the current position of vedolizumab in our current algorithm for IBD management and comment on future prospects of the drug. Vedolizumab appears to be a safe and effective option in the treatment of moderate-to-severe IBD in the short term. Long-term observational studies and post-marketing safety data are needed to ascertain the long-term efficacy and side effect profile.

Background: Longevinex® (L/RV) is a low dose hormetic over-the-counter (OTC) oral resveratrol (RV) based matrix of red wine solids, vitamin D3 and inositol hexaphosphate (IP6) with established bioavailability, safety, and short-term efficacy against the earliest signs of human atherosclerosis, murine cardiac reperfusion injury, clinical retinal neovascularization, and stem cell survival. We previously reported our short-term findings for dry and wet age-related macular degeneration (AMD) patients. Today we report long term (two to three year) clinical efficacy. Methods: We treated three patients including a patient with an AMD treatment resistant variant (polypoidal retinal vasculature disease). We evaluated two clinical measures of ocular structure (fundus autofluorescent imaging and spectral domain optical coherence extended depth choroidal imaging) and qualitatively appraised changes in macular pigment volume. We further evaluated three clinical measures of visual function (Snellen visual acuity, contrast sensitivity, and glare recovery to a cone photo-stress stimulus). Results: We observed broad bilateral improvements in ocular structure and function over a long time period, opposite to what might be expected due to aging and the natural progression of the patient’s pathophysiology. No side effects were observed. Conclusions: These three cases demonstrate that application of epigenetics has long-term efficacy against AMD retinal disease, when the retinal specialist has exhausted other therapeutic modalities.

Ventralis intermedius deep brain stimulation is an established intervention for medication-refractory essential tremor. Newer constant current stimulation technology offers theoretical advantage over the traditional constant voltage systems in terms of delivering a more biologically stable therapy. There are no previous reports on the outcomes of constant current deep brain stimulation in the treatment of essential tremor. This study aimed to evaluate the long-term efficacy of ventralis intermedius constant current deep brain stimulation in patients diagnosed with essential tremor. Essential tremor patients implanted with constant current deep brain stimulation for a minimum of three years were evaluated. Clinical outcomes were assessed using the Fahn-Tolosa-Marin tremor rating scale at baseline and postoperatively at the time of evaluation. The quality of life in the patients was assessed using the Quality of Life in Essential Tremor questionnaire. Ten patients were evaluated with a median age at evaluation of 74 years (range 66-79) and a mean follow up time of 49.7 (range 36-78) months since starting stimulation. Constant current ventralis intermedius deep brain stimulation was well tolerated and effective in all patients with a mean score improvement from 50.7 ± 5.9 to 17.4 ± 5.7 (p = 0.0020) in the total Fahn-Tolosa-Marin rating scale score (65.6%). Furthermore, the total combined mean Quality of Life in Essential Tremor score was improved from 56.2 ± 4.9 to 16.8 ± 3.5 (p value = 0.0059) (70.1%). This report shows that long-term constant current ventralis intermedius deep brain stimulation is a safe and effective intervention for essential tremor patients. © 2017 International Neuromodulation Society.

Contemporary Reflections on the Safety of Long-Term Aspirin Treatment for the Secondary Prevention of Cardiovascular Disease

Fanaroff, Alexander C.; Roe, Matthew T.

2018-01-01

Aspirin has been the cornerstone of therapy for the secondary prevention treatment of patients with cardiovascular disease since landmark trials were completed in the late 1970s and early 1980s that demonstrated the efficacy of aspirin for reducing the risk of ischemic events. Notwithstanding the consistent benefits demonstrated with apirin for both acute and chronic cardiovascular disease, there are a number of toxicities associated with aspirin that have been showcased by recent long-term clinical trials that have included an aspirin monotherapy arm. As an inhibitor of cyclooxygenase, aspirin impairs gastric mucosal protective mechanisms. Prior trials have shown that up to 15–20% of patients developed gastrointestinal symptoms with aspirin monotherapy and roughly 1% of patients per year had a clinically significant bleeding event, including 1 in 1000 patients who suffered an intracranial or fatal bleed. These risks have been shown to be compounded for patients with acute coronary syndromes (ACS) and those undergoing percutaneous coronary intervention (PCI), who are also treated with other anti-thrombotic agents during the acute care/procedural period, as well as for an extended time period afterwards. Given observations of substantial increases in bleeding rates from many prior long-term clinical trials that have evaluated aspirin together with other oral platelet inhibitors or oral anti-coagulants, the focus of contemporary research has pivoted towards tailored anti-thrombotic regimens that attempt to either shorten the duration of exposure to aspirin or replace aspirin with an alternative anti-thrombotic agent. While these shifts are occurring, the safety profile of aspirin when used for the secondary prevention treatment of patients with established cardiovascular disease deserves further consideration.

Long-term actuarial survivorship analysis of an interspinous stabilization system

Sénégas, Jacques; Pointillart, Vincent; Mangione, Paolo

2007-01-01

In 1986, an interspinous dynamic stabilization system (the prototype of the current Wallis implant) was designed to stiffen unstable operated degenerate lumbar segments with a hard interspinous blocker to limit extension and a tension band around the spinous processes to secure the implant and limit flexion. Restoring physiological mechanical conditions to the treated level(s) while preserving some intervertebral mobility was intended to treat low-back pain related to degenerative instability without increasing stress forces in the adjacent segments. The procedure was easily reversible. If low back pain persisted or recurred, the device was removed and stability was achieved using fusion. The intermediate-term results were promising, but the long-term safety and efficacy of this dynamic interspinous stabilization device has not been previously documented. We retrospectively reviewed the hospital files of all the patients (n = 241) who had this dynamic stabilization system implanted between 1987 and 1995, contacting as many as possible to determine the actuarial survivorship of the system. In this manner, 142 of the 241 patients (58.9%) were contacted by telephone. The endpoints used for the survivorship analysis were ‘any subsequent lumbar operation’ and ‘implant removal’. At 14 years follow-up, values of actuarial survivorship with 95% confidence interval were 75.9 ± 8.3 and 81.3 ± 6.8% for the endpoints ‘any subsequent lumbar operation’ and ‘implant removal’, respectively. There was no difference in survivorship of multiple-level implants with respect to single-level devices. Although the conclusions of the present study must be tempered by the 41% attrition rate, these findings support the long-term safety of this system, and possibly long-term protective action against adjacent-level degeneration by motion preservation. Outcomes at least equivalent to those of fusion were observed without the primary drawbacks of fusion. PMID:17426988

Despite several years of conducting formalized systematic occupational health and safety management (SOHSM), as required by law in Sweden and most other industrialized countries, there is still little evidence on how SOHSM should be approached to have an impact on employees' health. The aim of this study was to investigate the importance of SOHSM, considering structured routines and participation processes, for the incidence of occupational disorders and the prevalence of long-term work attendance among home care workers (HCWs). Municipal human service organizations were compared concerning (a) their structured routines and participation processes for SOHSM and (b) employee health, i.e. the municipal five-year incidence of occupational disorders and prevalence of work attendance among HCWs. National register-based data from the whole population of HCWs (n=154 773) were linked to register-data of occupational disorders and prevalence of long-term work attendance. The top managers and safety representatives in selected high- and low-incidence organizations (n=60) answered a questionnaire about structure and participation process of SOHSM. The results showed that prevalence of long-term work attendance was higher where structure and routines for SOHSM (policy, goals and plans for action) were well organized. Highly structured SOHSM and human resource management were also related to high organizational incidence of reported occupational disorders. Allocated budget and routines related to HCWs' influence in decisions concerning performance of care were also related to long-term work attendance. The participation processes had a weak effect on occupational disorders and work attendance among HCWs. Reporting occupational disorders may be a functional tool to stimulate the development of effective SOHSM, to improve the work environment and sustainable work ability.

To study the efficacy of long-term treatment with norethindrone acetate (NETA) in patients with rectovaginal endometriosis. This retrospective cohort study included 103 women with pain symptoms caused by rectovaginal endometriosis. Patients received NETA alone (2.5mg/day up to 5mg/day) for 5 years. Primary outcome was the degree of satisfaction with treatment after 5 years of progestin therapy. Secondary outcomes were the assessment of any variation in pain symptoms and the volumetric assessment of the disease by magnetic resonance imaging (MRI). Sixty-one women completed the 5-year follow-up (61/103, 59.2%) with 16 women withdrawing because of adverse effects (38.1%). Overall, 68.8% (42/61) of the women who completed the study were satisfied or very satisfied of this long term NETA treatment. This represents a 40.8% (42/103) of the patients enrolled. Intensity of chronic pelvic pain and deep dyspareunia significantly decreased during treatment (p<0.001 versus baseline at 1 and 5year). Dyschezia improved after 1-year respect to baseline (p=0.008) but remained stable between first and second year (p=0.409). At the end of 5 years treatment, a radiological partial response was observed in 33 patients (55.9%, n 33/59); a stable disease in 19 patients (32.2%, n 19/59). Seven women (7/59, 11.9%) displayed a volumetric increase of rectovaginal endometriosis under NETA treatment. Five-year therapy with NETA is safe and well tolerated by women with rectovaginal endometriosis. Due to its low cost and good pharmacological profile, it represents a good candidate for long-term treatment in this setting. Copyright © 2017 Elsevier B.V. All rights reserved.

Workplace violence (WPV) is becoming an issue that needs immediate attention in the United States, especially during this period as more states are adopting the "stand your ground laws to promote worker protection." This study was conducted to investigate how WPV has contributed to an unsafe environment for nurses and nursing assistants who work in long-term medical care facilities. A structure questionnaire was used to collect data for the study. Three facilities were sampled and 80 nurses and certified nursing assistants participated in the study. Ninety-two percent (n = 74) were female and 8% (n = 6) were male. Approximately 62% were black or African American, approximately 33% were Caucasians, and only 2% were from other ethnicities. We found that 65% of the participants had experienced WPV while 41% believed that management shows little or no concern for their safety. Approximately 23% of respondents believed that reporting supervisor's WPV act is an unsafe action. In addition, 22% of those who reported that they have experienced WPV believed that the work environment is not safe to perform their duties. This significant difference in perception of workplace safety between those who had experienced WPV and those who had not was significant (t = 3.95, df = 158, p < 0.0001). WPV is an epidemic problem that affects all health-care professionals. The findings of this study could help long-term medical care facilities' management identify the areas to focus on mitigating, controlling, and/or eliminating incidents of WPV.

Objective The efficacy and safety of abatacept in patients with juvenile idiopathic arthritis (JIA) who experienced an inadequate response to disease‐modifying antirheumatic drugs were previously established in a phase III study that included a 4‐month open‐label lead‐in period, a 6‐month double‐blind withdrawal period, and a long‐term extension (LTE) phase. The aim of this study was to present the safety, efficacy, and patient‐reported outcomes of abatacept treatment (10 mg/kg every 4 weeks) during the LTE phase, for up to 7 years of followup. Methods Patients enrolled in the phase III trial could enter the open‐label LTE phase if they had not achieved a response to treatment at month 4 or if they had received abatacept or placebo during the double‐blind period. Results One hundred fifty‐three (80.5%) of 190 patients entered the LTE phase, and 69 patients (36.3%) completed it. The overall incidence rate (events per 100 patient‐years) of adverse events decreased during the LTE phase (433.61 events during the short‐term phase [combined lead‐in and double‐blind periods] versus 132.39 events during the LTE phase). Similar results were observed for serious adverse events (6.82 versus 5.60), serious infections (1.13 versus 1.72), malignancies (1.12 versus 0), and autoimmune events (2.26 versus 1.18). American College of Rheumatology (ACR) Pediatric 30 (Pedi 30) responses, Pedi 70 responses, and clinically inactive disease status were maintained throughout the LTE phase in patients who continued to receive therapy. Improvements in the Child Health Questionnaire physical and psychosocial summary scores were maintained over time. Conclusion Long‐term abatacept treatment for up to 7 years was associated with consistent safety, sustained efficacy, and quality‐of‐life benefits in patients with JIA. PMID:26097215

Background The short-term safety profile of once-daily valbenazine (NBI-98854) has been evaluated in several double-blind, placebo-controlled (DBPC) trials in adults with tardive dyskinesia (TD) who had a diagnosis of schizophrenia/schizoaffective (SCHZ) disorder or mood disorder. Studies with longer treatment duration (up to 48 weeks) were conducted to evaluate the long-term safety of this novel drug in subjects with TD. Methods The pooled long-term exposure (LTE) population included valbenazine-treated subjects from 3 studies: KINECT (NCT01688037: 6-week DBPC, 6-week open-label); KINECT 3 (NCT02274558: 6-week DBPC, 42-week blinded extension, 4-week drug-free follow-up); KINECT 4 (NCT02405091: 48-week open-label, 4-week drug-free follow-up). Safety assessments included adverse events (AEs), laboratory tests, vital signs, electrocardiograms (ECGs), and extrapyramidal symptom (EPS) scales. Psychiatric stability was monitored using the Positive and Negative Syndrome Scale (PANSS) and Calgary Depression Scale for Schizophrenia (CDSS) (SCHZ subgroup), as well as the Montgomery-Åsberg Depression Rating Scale (MADRS) and Young Mania Rating Scale (YMRS) (mood subgroup). All data were analyzed descriptively. Results The LTE population included 430 subjects (KINECT, n = 46; KINECT 3, n = 220; KINECT 4, n = 164), 71.7% with SCHZ and 28.3% with a mood disorder; 85.5% were taking an antipsychotic (atypical only, 69.8%; typical only or typical + atypical, 15.7%). In the LTE population, treatment-emergent AEs (TEAEs) and discontinuations due to AEs were reported in 66.5% and 14.7% of subjects, respectively. The TEAE incidence was lower in the SCHZ subgroup (64.4%) than in the mood subgroup (71.9%). The 3 most common TEAEs in the SCHZ subgroup were urinary tract infection (UTI, 6.1%), headache (5.8%), and somnolence (5.2%). The 3 most common TEAEs in the mood subgroup were headache (12.4%), UTI (10.7%), and somnolence (9.1%). Mean score changes from baseline to end of treatment

Aim To evaluate the long‐term safety and efficacy of canagliflozin as add‐on therapy in patients with type 2 diabetes mellitus (T2DM) who had inadequate glycaemic control with teneligliptin monotherapy. Methods This open‐label 52‐week study was conducted in Japan. Patients received canagliflozin 100 mg added to teneligliptin 20 mg orally once daily for 52 weeks. The safety endpoint was the incidence of adverse events (AEs). The efficacy endpoints included changes in glycated haemoglobin (HbA1c), fasting plasma glucose (FPG) and body weight from baseline to week 52 (with last observation carried forward). Results Overall, 153 patients entered the treatment period and 142 completed the study. The overall incidence rates of AEs and drug‐related AEs were 69.9% and 22.9%, respectively. Most AEs and drug‐related AEs were mild or moderate in severity. There were no previously undescribed safety signals. The mean changes in HbA1c, FPG and body weight were −0.99% (95% confidence interval [CI] −1.12 to −0.85), −38.6 mg/dL (95% CI −43.4 to −33.9) and −3.92% (95% CI −4.53 to −3.31), respectively. These effects were maintained for 52 weeks without attenuation. HbA1c and body weight were both decreased in 82.24% of patients at the end of the treatment period. Reductions in postprandial glucose were observed at weeks 24 and 52. Conclusions No new safety risks with this combination were identified, and sustained improvements in HbA1c, FPG and body weight were observed. The findings suggest that long‐term co‐administration of canagliflozin with teneligliptin is well tolerated and effective in Japanese patients with T2DM who have inadequate glycaemic control on teneligliptin alone.

Sacral nerve stimulation (SNS) is FDA approved as second-line therapy for both urinary and bowel control. However, there is limited evidence regarding long term safety. We determined adverse events associated with SNS among Medicare beneficiaries. We used the 5% national random sample of Medicare claims for 2001-2011 to identify patients. Patients who underwent SNS implantation were identified with Current Procedure Terminology (CPT-4) codes. We determined safety of SNS using analysis of complication occurrences on day of surgery and during 5 years following initial procedure. SAS v9.3 statistical package was used. One thousand four hundred seventy-four patients underwent treatment with SNS in the 5% national sample of Medicare patients within the time period. Representative of real-world patients undergoing SNS surgery, comorbidities included hypertension (69.3%), diabetes (29.4%), chronic pulmonary disease (25.5%), hypothyroidism (25.2%), and depression (22.7%). Few complications occurred on day of surgery. At 90 days, 3.2% of patients had bowel complications, 2.0% urological, 9.4% infectious, and 1.5% stroke. Overall, bowel, neurological health event occurrences were consistent with prior year rates, while infectious events decreased. Of 206 patients who were followed for at least 5 years, 17.3% had devices removed and 11.3% replaced, with 26.1% having at least one of those, leaving 73.9% with original devices. Urological, infectious, and bowel complication occurrences were low after SNS among Medicare beneficiaries with multiple comorbidities. There were infrequent serious complications like hemorrhage and stroke postoperatively. Although SNS appears safe in this high-risk population, a comprehensive registry will ensure continuous safety. © 2014 Wiley Periodicals, Inc.

Dynamical model of long-term synaptic plasticity

2002-01-01

Long-term synaptic plasticity leading to enhancement in synaptic efficacy (long-term potentiation, LTP) or decrease in synaptic efficacy (long-term depression, LTD) is widely regarded as underlying learning and memory in nervous systems. LTP and LTD at excitatory neuronal synapses are observed to be induced by precise timing of pre- and postsynaptic events. Modification of synaptic transmission in long-term plasticity is a complex process involving many pathways; for example, it is also known that both forms of synaptic plasticity can be induced by various time courses of Ca2+ introduction into the postsynaptic cell. We present a phenomenological description of a two-component process for synaptic plasticity. Our dynamical model reproduces the spike time-dependent plasticity of excitatory synapses as a function of relative timing between pre- and postsynaptic events, as observed in recent experiments. The model accounts for LTP and LTD when the postsynaptic cell is voltage clamped and depolarized (LTP) or hyperpolarized (LTD) and no postsynaptic action potentials are evoked. We are also able to connect our model with the Bienenstock, Cooper, and Munro rule. We give model predictions for changes in synaptic strength when periodic spike trains of varying frequency and Poisson distributed spike trains with varying average frequency are presented pre- and postsynaptically. When the frequency of spike presentation exceeds ≈30–40 Hz, only LTP is induced. PMID:12114531

Objectives To update the evidence for the efficacy and safety of (b)biological and (ts)targeted-synthetic disease-modifying anti-rheumatic drugs (DMARDs) in patients with axial spondyloarthritis (axSpA) to inform the 2016 update of the Assessment of SpondyloArthritis international Society/European League Against Rheumatism (ASAS/EULAR) recommendations for the management of axSpA. Methods Systematic literature review (2009–2016) for randomised controlled trials (RCT), including long-term extensions, strategy trials and observational studies (the latter was only for safety assessment and a comparator was required). Interventions were any bDMARD or tsDMARD. All relevant efficacy and safety outcomes were included. Results 76 papers and 24 abstracts fulfilled the inclusion criteria. Large treatment effects were found both in radiographic axSpA (r-axSpA) and non-radiographic axSpA (nr-axSpA) for all tumour necrosis factor inhibitors (TNFi) (NNT to achieve ASAS40 response ranged between 2.6–5.2 for r-axSpA and 2.3–5.4 for nr-axSpA). For nr-axSpA, efficacy was superior for those who had objective signs of inflammation (positive C reactive protein or inflammation on MRI-SI). Secukinumab 150 mg has shown efficacy in two phase 3 RCTs (NNT to achieve ASAS40 response: 3.4 and 4.0). Ustekinumab and tofacitinib have shown positive results in phase 2/proof-of-concept trials; trials with apremilast, rituximab, interleukin (IL)-6 antagonists and abatacept have failed their primary end points. New (unknown) safety signals were not found in the trials but long-term observational safety data for TNFi are still scarce. Conclusions New evidence supports the efficacy and safety of TNFi both in r-axSpA and nr-axSpA. Secukinumab is the first drug targeting the IL-17 pathway in r-axSpA that has shown efficacy.

The present study was designed to evaluate the long-term efficacy and safety of once-daily enoxaparin plus warfarin for the outpatient ambulatory treatment of lower-limb deep venous thrombosis (DVT). A total of 246 patients, comprising 128 men (mean age, 54.28±16.48 years) and 118 women (mean age, 50.11±16.47 years) with symptomatic lower extremity DVT, were included in this open-label, single-arm, multicenter, phase IV clinical trial conducted at 14 centers in Turkey. All patients were administered subcutaneous enoxaparin (1.5 mg/kg, once-daily) until international normalized ratio (INR) levels reached to 2 to 3, followed by oral warfarin (5 mg/d) for at least 3 months and elastic compression stockings (30-40 mm Hg). Clinical signs (leg circumference), symptoms (edema, pain, tenderness), recanalization rates upon duplex ultrasound examination, laboratory findings (D-dimer and INR levels), and postthrombotic syndrome status with CEAP classification were the efficacy parameters evaluated every 3 months during 18 months of follow-up. Safety end points included minor and major bleeding as well as serious adverse events. Ambulatory treatment with enoxaparin plus warfarin significantly reduced physical symptoms, including tenderness, edema, pain (P<.001), and the circumference of the affected leg (P<.001). The leg circumference difference in almost all patients was <1.5 cm at the end of 18 months (P<.001). Recanalization rates for occluded iliofemoral vein were 76.1% at 3 months and 86.5% at 18 months (P<.001). An early and significant decrease obtained in D-dimer levels on day 10 continued to decline significantly until month 6 and remained unchanged afterwards (P<.001). Of four patients diagnosed with major bleeding during oral anticoagulant use, three recovered with conservative treatment (reduction in hemoglobin levels in 2 developed at visit 2 [day 10] and intracranial bleeding in 1 developed at visit 3 [day 30]), and one patient required a hysterectomy after

There are versatile modalities to achieve noninvasive fat reduction, and most of them have proven to be effective for circumferential reduction of local fat tissue, without any serious or permanent adverse effects. However, the follow-up time is short, ranging from 1 to 24 weeks. Most of the patients would like to know how long will its effect last and whether there is long-term side effect or not. The aim of this study was to assess the long-term efficacy and safety of combination therapy of focused ultrasound and radio frequency for noninvasive body contouring. Thirty-two Asian subjects received three sequential combination therapies of focused ultrasound and radio-frequency treatments every 2 weeks in the abdominal region and were followed up 1 month and 1 year after the last treatment. After a year, 5 patients were loss follow-up and 2 were pregnant. Finally, 25 healthy Asian subjects (18 females and 7 males) were enrolled in this study. Safety parameters and adverse events were recorded. The mean body weight change remained constant without a significant change 1 year after treatment and was 0.1 ± 1.2 kg (p = 0.513). The mean abdominal circumference change between 1 month and 1 year after the last treatment was 0.4 ± 1.2 cm and was not significant (p = 0.169). The relationships between weight change and circumference change of the 23 patients were tested using Spearman's rho correlation coefficient. There was a correlation between weight change and circumference change (0.73; p = 0.000). The procedure was safe without a recordable long-term adverse event. The combination therapies of nonthermally focused ultrasound and radio-frequency treatments for body contouring in the abdominal region are effective and may show positive results for at least a year if patients can maintain their body weight. The procedure is safe without recordable long-term adverse events in this study.

In this study we assessed the long-term efficacy and safety of disopyramide for patients with obstructive hypertrophic cardiomyopathy (HCM). It has been reported that disopyramide may reduce left ventricular outflow gradient and improve symptoms in patients with HCM. However, long-term efficacy and safety of disopyramide has not been shown in a large cohort. Clinical and echocardiographic data were evaluated in 118 obstructive HCM patients treated with disopyramide at 4 HCM treatment centers. Mortality in the disopyramide-treated patients was compared with 373 obstructive HCM patients not treated with disopyramide. Patients were followed with disopyramide for 3.1 +/- 2.6 years; dose 432 +/- 181 mg/day (97% also received beta-blockers). Seventy-eight patients (66%) were maintained with disopyramide without the necessity for major non-pharmacologic intervention with surgical myectomy, alcohol ablation, or pacing; outflow gradient at rest decreased from 75 +/- 33 to 40 +/- 32 mm Hg (p < 0.0001) and mean New York Heart Association functional class from 2.3 +/- 0.7 to 1.7 +/- 0.6 (p < 0.0001). Forty other patients (34%) could not be satisfactorily managed with disopyramide and required major invasive interventions because of inadequate symptom and gradient control or vagolytic side effects. All-cause annual cardiac death rate between disopyramide and non-disopyramide-treated patients did not differ significantly, 1.4% versus 2.6%/year (p = 0.07). There was also no difference in sudden death rate, 1.0%/year versus 1.8%/year (p = 0.08). Two-thirds of obstructed HCM patients treated with disopyramide could be managed medically with amelioration of symptoms and about 50% reduction in subaortic gradient over >/=3 years. Disopyramide therapy does not appear to be proarrhythmic in HCM and should be considered before proceeding to surgical myectomy or alternate strategies.

Although short-term use (≤2 months) of atomized topical nasal steroids has been shown to be safe and effective, the long-term safety has yet to be demonstrated. The aim of this study was to determine the impact of long-term topical budesonide treatment via the mucosal atomization device (MAD) on the hypothalamic-pituitary-adrenal axis (HPAA) and intraocular pressure (IOP). A cross-sectional study of patients with chronic rhinosinusitis (CRS), with or without nasal polyposis, managed with daily nasal budesonide via MAD was conducted at a tertiary rhinology center. Patients using systemic steroids within 3 months of assessment were excluded. HPAA impact was assessed using the cosyntropin stimulation test for adrenal function and a survey of relevant symptomatology. Patients also underwent tonometry to assess for elevated IOP potentially related to corticosteroid use. A total of 100 CRS patients were recruited with a mean budesonide treatment duration of 23.5 months (range, 6-37 months). Stimulated cortisol response was diminished in 3 patients (3%). No patients with adrenal suppression had relevant symptomatology. IOP was elevated in 6 patients (6%). These findings suggest that there is a risk of adrenal suppression and raised IOP associated with the long-term use of topical nasal budesonide via MAD. Otolaryngologists should consider periodic surveillance for these adverse events in this patient cohort. © 2017 ARS-AAOA, LLC.

Efficacy of lifestyle modification for long-term weight control.

Wadden, Thomas A; Butryn, Meghan L; Byrne, Kirstin J

2004-12-01

A comprehensive program of lifestyle modification induces loss of approximately 10% of initial weight in 16 to 26 weeks, as revealed by a review of recent randomized controlled trials, including the Diabetes Prevention Program. Long-term weight control is facilitated by continued patient-therapist contact, whether provided in person or by telephone, mail, or e-mail. High levels of physical activity and the consumption of low-calorie, portion-controlled meals, including liquid meal replacements, can also help maintain weight loss. Additional studies are needed of the effects of macronutrient content (e.g., low-fat vs. low-carbohydrate diets) on long-term changes in weight and health. Research also is needed on effective methods of providing comprehensive weight loss control to the millions of Americans who need it.

Many breast cancer survivors feel constrained in discussing their cancer experience with others. Limited evidence suggests that social constraints (e.g., avoidance and criticism) from loved ones may negatively impact breast cancer survivors' global health, but research has yet to examine relationships between social constraints and common physical symptoms. Informed by social cognitive processing theory, this study examined whether perceived social constraints from partners and healthcare providers (HCPs) were associated with fatigue, sleep disturbance, and attentional functioning among long-term breast cancer survivors (N = 1052). In addition, avoidant coping and self-efficacy for symptom management were examined as potential mediators of these relationships. Long-term breast cancer survivors (mean years since diagnosis = 6) completed questionnaires assessing social constraints from partners and HCPs, avoidant coping, self-efficacy for symptom management, and symptoms (i.e., fatigue, sleep disturbance, and attentional functioning). Structural equation modeling was used to evaluate the hypothesized relationships among variables in two models: one focused on social constraints from partners and one focused on social constraints from HCPs. Both models demonstrated good fit. Consistent with theory and prior research, greater social constraints from both partners and HCPs were associated with greater symptom burden (i.e., greater fatigue and sleep disturbance, poorer attentional functioning). In addition, all relationships were mediated by avoidant coping and self-efficacy for symptom management. Findings are consistent with social cognitive processing theory and suggest that symptom management interventions may be enhanced by addressing the impact of social constraints from survivors' partners and HCPs on their coping and self-efficacy.

Background Bronchial thermoplasty (BT) has previously been shown to improve asthma control out to 2 years in patients with severe persistent asthma. Objective To assess effectiveness and safety of BT in asthma patients 5 years post therapy. Methods BT-treated subjects from the Asthma Intervention Research 2 (AIR2) Trial (ClinicalTrials.gov NCT01350414) were evaluated annually for 5 years to assess long-term safety of BT and durability of treatment effect. Outcomes assessed post-BT included severe exacerbations, adverse events, healthcare utilization, spirometry data, and high resolution computed tomography (HRCT) scans. Results 162/190 BT-treated subjects (85.3%) from the AIR2 Trial completed 5 years of follow-up. The proportion of subjects experiencing severe exacerbations and Emergency Room visits, and the rates of events in each of years 1 to 5 remained low and were less than those observed in the 12 months prior to BT treatment (average 5 year reduction in proportions: 44% for exacerbations and 78% for ER visits). Respiratory adverse events and respiratory-related hospitalizations remained unchanged in Years 2 through 5 as compared to the first year after BT. Pre-BD FEV1 values remained stable between years 1 and 5 after BT, despite a 17% reduction in average daily inhaled corticosteroid dose. HRCT scans from baseline to 5 years after BT showed no structural abnormalities that could be attributed to BT. Conclusions These data demonstrate the 5-year durability of the benefits of BT with regard to both asthma control (based on maintained reduction in severe exacerbations and ER visits for respiratory symptoms) and safety. BT has become an important addition to our treatment armamentarium and should be considered for patients with severe persistent asthma who remain symptomatic despite taking ICS (inhaled corticosteroids) and LABA (long-acting-β2-agonists).

Clobetasol propionate (CP) shampoo 0.05% is an efficacious and safe treatment for scalp psoriasis. The aim of this double-blind, randomized, placebo-controlled study was to determine if CP shampoo is suitable for long-term disease control. Participants with moderate to severe scalp psoriasis (global severity score [GSS] of 3 or 4 on a scale of 0 [clear] to 5 [very severe]) first received once daily CP shampoo treatment for up to 4 weeks. Responders were subsequently randomized to receive the CP shampoo or vehicle twice weekly maintenance regimen for up to 6 months. When relapse occurred (defined as GSS > 2), participants resumed once daily CP shampoo treatment; when symptoms diminished (GSS < or = 2), they readopted the twice weekly maintenance regimen. At all visits significantly more participants treated with CP shampoo did not relapse compared with participants treated with vehicle (P < .001). Only approximately one-third of participants treated with vehicle remained relapse free at 1 month, while this rate was observed approximately 3.5 months later (4.5 months after baseline of maintenance phase) in the CP shampoo group. After 6 months 31.1% (33/106) of participants in the CP shampoo group were still relapse free versus 8.1% (9/111) of participants in the vehicle group. There was no greater incidence of skin atrophy, telangiectasia, or hypothalamic-pituitary-adrenal (HPA) axis suppression in the CP shampoo group compared with the vehicle group. Clobetasol propionate shampoo is efficacious and safe for acute management and long-term maintenance of moderate to severe scalp psoriasis.

Methods and Materials: This study was approved by our institutional review board and was compliant with the Health Insurance Portability and Accountability Act. Forty patients with hepatic neuroendocrine metastases were treated with {sup 90}Y radioembolization at a single center. Toxicity was assessed using National Cancer Institute Common Terminology Criteria v3.0. Response to therapy was assessed by World Health Organization (WHO) guidelines for size and European Association for the Study of the Liver disease (EASL) guidelinesmore » for necrosis. Time to response and overall survival were calculated using the Kaplan-Meier method. Univariate and multivariate analyses were performed. Results: The median dose was 113 Gy (29-299 Gy). Clinical toxicities included fatigue (63%), nausea/vomiting (40%), abdominal pain (18%), fever (8%), diarrhea and weight loss (5%); Grade 3 and 4 bilirubin toxicities were experienced by 2 patients and 1 patient, respectively. Different responses were noted by WHO (complete response, 1.2%; partial response, 62.7%) and EASL (complete response, 20.5%; partial response, 43.4%). Median time to response was 4 and 4.9 months by lesion and patient, respectively. The 1-, 2-, and 3-year overall survival rates were 72.5%, 62.5%, and 45%, respectively. Eastern Cooperative Oncology Group (ECOG) performance score 0 (p < 0.0001), tumor burden {<=}25% (p = 0.0019), albumin {>=}3.5 g/dL (p = 0.017), and bilirubin {<=}1.2 mg/dL (p = 0.002) prognosticated survival on univariate analysis; only ECOG performance score 0 and bilirubin {<=}1.2 mg/dL prognosticated better survival outcome on multivariate analysis (p = 0.0001 and p = 0.02). Conclusion: Yttrium-90 therapy for hepatic neuroendocrine metastases leads to satisfactory tumor response and patient

As relapse after completed cognitive behavior therapy (CBT) for obsessive-compulsive disorder (OCD) is common, many treatment protocols include booster programs to improve the long-term effects. However, the effects of booster programs are not well studied. In this study, we investigated the long-term efficacy of Internet-based CBT (ICBT) with therapist support for OCD with or without an Internet-based booster program. A total of 101 participants were included in the long-term follow-up analysis of ICBT. Of these, 93 were randomized to a booster program or no booster program. Outcome assessments were collected at 4, 7, 12 and 24 months after receiving ICBT. The entire sample had sustained long-term effects from pre-treatment to all follow-up assessments, with large within-group effect sizes (Cohen's d = 1.58-2.09). The booster group had a significant mean reduction in OCD symptoms compared to the control condition from booster baseline (4 months) to 7 months, but not at 12 or 24 months. Participants in the booster group improved significantly in terms of general functioning at 7, 12 and 24 months, and had fewer relapses. Kaplan-Meier analysis also indicated a significantly slower relapse rate in the booster group. The results suggest that ICBT has sustained long-term effects and that adding an Internet-based booster program can further improve long-term outcome and prevent relapse for some OCD patients.

Introduction With long-term follow-up, whether biodegradable polymer drug-eluting stents (DES) is efficient and safe in primary percutaneous coronary intervention (PCI) remains a controversial issue. This study aims to assess the long-term efficacy and safety of DES in PCI for ST-segment elevation myocardial infarction (STEMI). Material and methods A prospective, randomized single-blind study with 3-year follow-up was performed to compare biodegradable polymer DES with durable polymer DES in 332 STEMI patients treated with primary PCI. The primary end point was major adverse cardiac events (MACE) at 3 years after the procedure, defined as the composite of cardiac death, recurrent infarction, and target vessel revascularization. The secondary end points included in-segment late luminal loss (LLL) and binary restenosis at 9 months and cumulative stent thrombosis (ST) event rates up to 3 years. Results The rate of the primary end points and the secondary end points including major adverse cardiac events, in-segment late luminal loss, binary restenosis, and cumulative thrombotic event rates were comparable between biodegradable polymer DES and durable polymer DES in these 332 STEMI patients treated with primary PCI at 3 years. Conclusions Biodegradable polymer DES has similar efficacy and safety profiles at 3 years compared with durable polymer DES in STEMI patients treated with primary PCI. PMID:24482648

To assess efficacy and safety of citalopram compared to quetiapine and olanzapine for the treatment of agitation in patients with Alzheimer disease (AD). Longitudinal, 6-month study. Nursing home (NH). 75 NH residents with AD and agitation, randomized to citalopram (n = 25), quetiapine (n = 25), or olanzapine (n = 25). Changes in Neuropsychiatric Inventory (NPI) agitation subscale score and the modified Alzheimer Disease Cooperative Study-Clinical Global Impression of Change (mADCS-CGIC) were used to assess treatment efficacy. Participants were surveilled for adverse health outcomes. Citalopram treatment (30±5.8 mg/d) resulted in similar 6-month efficacy compared to both quetiapine (94.0±40.4 mg/d) and olanzapine (5.2±1.6 mg/d), lower occurrence of falls than olanzapine [odds ratio (OR) = 0.81, 95% confidence interval (CI) = 0.68-0.97, P = .012], lower incidence of orthostatic hypotension than both quetiapine (OR = 0.80, 95% CI = 0.66-0.95, P = .032) and olanzapine (OR = 0.75, 95% CI = 0.69-0.91, P = .02), and less all-cause hospitalizations than both quetiapine (OR = 0.92, 95% CI = 0.88-0.95, P = .016) and olanzapine (OR = 0.78, 95% CI = 0.64-0.92, P = .004), after multiple adjustment for potentially confounding variables. No differences were observed for cognitive and functional decline, QTc prolongation, and infections. Citalopram resulted in similar efficacy and less adverse outcomes when compared to 2 atypical antipsychotics for treatment of agitation in NH residents with AD. Replication of these findings and assessment of long-term efficacy and safety of citalopram for treatment of neuropsychiatric symptoms in dementia are needed.

OBJECTIVES: We evaluated the long term therapeutic efficacy of 80 watt photo-selective vaporization of the prostate (PVP) in patients suffering from lower urinary tract symptoms (LUTS) secondary to prostatic obstruction. MATERIAL & METHODS: 150 unselected patients at the average age 73 (range 51-92) and a mean American Society of Anesthesiologists score of 2.4 (median 2.0), of whom 33% were medicated with acetylsalicylic acid and 5% were anticoagulated with warfarin. Inclusion/exclusion criteria were the same as for TUR-P at our institution. First patient was operated March 2004 and yearly follow-up of all patients has been attempted for 5 years. Follow-up variables have included yearly creatinine, PSA, IPSS, ØOL, post-void residual urin and maximum/average urine flow rate. RESULTS: At 12 and 24 months postoperatively, the following parameters were significantly (p<0.001) improved: trans-rectal ultrasound, international prostate symptom score, quality of life score, post-void residual urine volume, flow max/average, opening pressure, pressure @ flow-max, and micturition resistance. At 48 and 60 months creatinine, PSA, IPSS, ØOL, post-void residual urin and maximum/average urine flow rates were still significantly (p<0.001) improved compared to pre-operative values. CONCLUSION: Up to 5 year follow-up reveals that 80 watt PVP provides significant and stable symptom relief as well as objective improvement in residual urine and flowmetric outcomes.

Liquid nitrogen endoscopic spray cryotherapy can safely and effectively eradicate high-grade dysplasia in Barrett's esophagus (BE-HGD). Long-term data on treatment success and safety are lacking. To assess the long-term safety and efficacy of spray cryotherapy in patients with BE-HGD. Single-center, retrospective study. Tertiary-care referral center. A total of 32 patients with BE-HGD of any length. Patients were treated with liquid nitrogen spray cryotherapy every 8 weeks until complete eradication of HGD (CE-HGD) and intestinal metaplasia (CE-IM) was found by endoscopic biopsy. Surveillance endoscopy with biopsies was performed for at least 2 years. CE-HGD, CE-IM, durability of response, disease progression, and adverse events. CE-HGD was 100% (32/32), and CE-IM was 84% (27/32) at 2-year follow-up. At last follow-up (range 24-57 months), CE-HGD was 31/32 (97%), and CE-IM was 26/32 (81%). Recurrent HGD was found in 6 (18%), with CE-HGD in 5 after repeat treatment. One patient progressed to adenocarcinoma, downgraded to HGD after repeat cryotherapy. BE segment length ≥3 cm was associated with a higher recurrence of IM (P = .004; odds ratio 22.6) but not HGD. No serious adverse events occurred. Stricture was seen in 3 patients (9%), all successfully dilated. Retrospective study design, small sample size. In patients with BE-HGD, liquid nitrogen spray cryotherapy has an acceptable safety profile and success rate for eliminating HGD and IM and is associated with a low rate of recurrence or progression to cancer with long-term follow-up.

Abstract Conventional synthetic disease-modifying anti-rheumatic drugs, including methotrexate, may not be tolerated by all patients with rheumatoid arthritis (RA), and limited international data for etanercept (ETN) monotherapy are available. The aim of this review was to summarize the clinical program for ETN monotherapy in Japanese patients with RA, which has included a pharmacokinetic study, clinical trials for registration, long-term studies, and once-weekly dosing studies. Pharmacokinetic results showed that serum concentrations of ETN were linear with dose levels and were similar to other international studies. Across interventional studies, 652 Japanese patients with active RA were treated with ETN. In the registration studies, ETN treatment led to consistent improvement in American College of Rheumatology 20/50/70 scores, European League Against Rheumatism Good Response, Disease Activity Score 28 erythrocyte sedimentation rate remission, and Health Assessment Questionnaire disability index. In the long-term studies, efficacy was maintained for up to 180 weeks. Similar results were seen in the once-weekly studies. Across the studies, more than 870 patient-years of exposure to ETN were recorded. Discontinuations owing to lack of efficacy or adverse events were modest and no new safety signals were recorded. These studies demonstrated that ETN monotherapy is efficacious and well-tolerated in Japanese patients with RA.

Literature provides reports only of a limited follow-up single injection of botulinum toxin-A (BoNT-A) in patients with sialorrhea. The aim of our study is to evaluate the long-lasting efficacy and safety of ultrasound-guided BoNT-A injections for severe sialorrhea secondary to neurological dysphagia. We enrolled 38 severe adult sialorrhea patients referred consecutively to the neurology unit and performed bilateral parotid and submandibular gland BoNT-A injections under ultrasound guidance. The outcomes of the study were reduction of sialorrhea, duration of therapeutic effect, and subjective patient- and caregiver-reported satisfaction. A total of 113 BoNT-A administrations were given during the study period with a mean duration of follow-up of 20.2 ± 4.4 months. We observed a significant decrease from baseline in mean number of daily aspirations and a significant improvement in patient- and caregiver-reported outcomes following ultrasound-guided BoNT-A injections (p < 0.001 vs baseline for all comparisons) and the mean duration of the efficacy was 5.6 ± 1 months. No major treatment-related adverse events occurred and a low incidence of minor adverse events was reported. This study confirms the long-lasting efficacy and safety of ultrasound-guided BoNT-A injections for sialorrhea, regardless of the causative neurological disorder. These results should encourage the use of BoNT-A in the treatment of severe sialorrhea and highlight the role of ultrasound guidance to obtain optimal results in terms of safety and reproducible outcomes.

Ulcerative colitis (UC), a chronic, relapsing, and remitting inflammatory bowel disease, requires long-term treatment to maintain remission. In this study, the long-term safety and tolerability of mesalamine granules (MG) therapy was evaluated in the maintenance of UC remission. Previous prospective studies evaluating different oral mesalamine formulations have not exceeded a duration of 14 months. A phase 3, multicenter, 24-month, open-label extension study evaluating MG 1.5 g once daily in patients who achieved previous remission from mild to moderate UC was performed. Eligible patients had successfully participated in 1 of 2 previous 6-month double-blind, placebo-controlled trials or were new patients in remission. Safety assessments included monitoring of adverse events (AEs) and clinical laboratory tests. Risk of UC recurrence was assessed by the occurrence of UC-related AEs. Of the 393 patients enrolled (280 from the double-blind studies; 113 new patients), 388 were included in the safety population. The most common AEs included nasopharyngitis (13.9%), headache (11.6%), and diarrhea (10.8%), and the incidence of these events was generally lower in the MG group versus historical placebo group from the double-blind studies. Pancreatic, renal, and hepatic AEs occurred in 23 patients (5.9%). The risk of UC-related AEs was low and was maintained for 24 months during the open-label study. Once-daily MG has a favorable safety profile for the maintenance of remission for up to 2 years in patients with UC.

Focused Ultrasound (FUS) coupled with intravenous administration of microbubbles (MB) is a non-invasive technique that has been shown to reliably open (increase the permeability of) the blood-brain barrier (BBB) in multiple in vivo models including non-human primates (NHP). This procedure has shown promise for clinical and basic science applications, yet the safety and potential neurological effects of long term application in NHP requires further investigation under parameters shown to be efficacious in that species (500 kHz, 200-400 kPa, 4-5 μm MB, 2 minute sonication). In this study, we repeatedly opened the BBB in the caudate and putamen regions of the basal ganglia of 4 NHP using FUS with systemically-administered MB over 4-20 months. We assessed the safety of the FUS with MB procedure using MRI to detect edema or hemorrhaging in the brain. Contrast enhanced T1-weighted MRI sequences showed a 98% success rate for openings in the targeted regions. T2-weighted and SWI sequences indicated a lack edema in the majority of the cases. We investigated potential neurological effects of the FUS with MB procedure through quantitative cognitive testing of' visual, cognitive, motivational, and motor function using a random dot motion task with reward magnitude bias presented on a touchpanel display. Reaction times during the task significantly increased on the day of the FUS with MB procedure. This increase returned to baseline within 4-5 days after the procedure. Visual motion discrimination thresholds were unaffected. Our results indicate FUS with MB can be a safe method for repeated opening of the BBB at the basal ganglia in NHP for up to 20 months without any long-term negative physiological or neurological effects with the parameters used.

Collagenase Option for Reduction of Dupuytren Long-Term Evaluation of Safety Study was a 5-year noninterventional follow-up study to determine long-term efficacy and safety of collagenase clostridium histolyticum (CCH) treatment for Dupuytren contracture. Patients from previous CCH clinical studies were eligible. Enrolled patients were evaluated annually for contracture and safety at 2, 3, 4, and 5 years after their first injection (0.58 mg) of CCH. In successfully treated joints (≤ 5° contracture following CCH treatment), recurrence was defined as 20° or greater worsening (relative to day 30 after the last injection) with a palpable cord or any medical/surgical intervention to correct new/worsening contracture. A post hoc analysis was also conducted using a less stringent threshold (≥ 30° worsening) for comparison with criteria historically used to assess surgical treatment. Of 950 eligible patients, 644 enrolled (1,081 treated joints). At year 5, 47% (291 of 623) of successfully treated joints had recurrence (≥ 20° worsening)-39% (178 of 451) of metacarpophalangeal and 66% (113 of 172) of proximal interphalangeal joints. At year 5, 32% (198 of 623) of successfully treated joints had 30° or greater worsening (metacarpophalangeal 26% [119 of 451] and proximal interphalangeal 46% [79 of 172] joints). Of 105 secondary interventions performed in the successfully treated joints, 47% (49 of 105) received fasciectomy, 30% (32 of 105) received additional CCH, and 23% (24 of 105) received other interventions. One mild adverse event was attributed to CCH treatment (skin atrophy [decreased ring finger circumference from thinning of Dupuytren tissue]). Antibodies to clostridial type I and/or II collagenase were found in 93% of patients, but over the 5 years of follow-up, this did not correspond to any reported clinical adverse events. Five years after successful CCH treatment, the overall recurrence rate of 47% was comparable with published recurrence rates after

To evaluate the safety and efficacy of ultrasound-guided low-power microwave ablation (MWA) for the treatment of papillary thyroid microcarcinoma (PTMC) with a 3-year follow-up. A total of 21 nodules diagnosed as PTMC from the 15 patients were performed with MWA at a power of 20 W. The images of the nodules were recorded by ultrasound before MWA and 1, 3, 6, 12 months after MWA, and every 6 months thereafter, respectively. The volumes of the nodules were compared before MWA and at each follow-up point after MWA. The volume reduction rate (VRR) of nodules was also calculated. The mean volume of the nodules was 134.3 ± 129.8 mm 3 initially (the range was 7.4-423.8 mm 3 ), which decreased significantly to 2.3 ± 10.5 mm 3 (the range was 0-48.1 mm 3 ) of the ablation area (P = 0.000) at the follow-up point of 36 months with a mean VRR as 98.78 ± 5.61% (the range was 74.28-100%). During the follow-up period (the range was 36-48 months), 20 of the 21 nodules were completely absorbed and no recurrent nodule was found. After a long-term follow-up of 3 years, the low power MWA showed a good safety and efficacy for the treatment of PTMC. In addition to surgery and active surveillance, MWA might be another alternative for patients with PTMC.

Anticonvulsant drugs are increasingly being used for alcohol detoxification in in- and outpatient settings. The aim of this study was to examine the efficacy, medical safety and mid-term outcome of levetiracetam, a drug with no marked liver toxicity, for outpatient alcohol detoxification. This was an open-label observational study. After screening eligibility for outpatient alcohol detoxification, patients were seen daily for 5 days and received levetiracetam in a flexible dosage regime between 500 and 4 000 mg/d for a maximum of 7 days. Diazepam was used as a rescue medication. The severity of alcohol withdrawal was evaluated daily using the ALCOHOL WITHDRAWAL SYNDROME SCALE (AWSS). Mid-term treatment outcome was assessed at a 6-month follow-up. A total number of 131 consecutively admitted alcohol-dependent patients received an outpatient detoxification treatment, 122 (93.1%) completed the programme successfully. The mean initial dose of levetiracetam was 1 850 mg/d. Alcohol withdrawal syndrome as indicated by the AWSS score decreased clearly over 5 days. Overall, the medication was well tolerated. There was no treatment discontinuations due to side effects of levetiracetam. No serious medical complications, especially seizures or deliria, were observed during the detoxification. At the 6-month follow-up, 57 patients (43.5%) were still abstinent. Patients with previous detoxifications had a significant higher risk for relapse (HR=1.88; p=0.016; CI 95%: 1.12-3.14) than patients without previous treatments. The findings of this study provide some evidence that levetiracetam is an efficacious and safe treatment option for outpatient alcohol detoxification. Further randomised, controlled trials including mid- and long-term follow-ups are needed to confirm these findings. Copyright Georg Thieme Verlag KG Stuttgart New York.

Efficacy and Effectiveness of Lithium in the Long-Term Treatment of Bipolar Disorders: An Update 2018.

2018-06-13

For more than 40 years, lithium has been the gold standard in the long-term treatment of bipolar disorders. In the course of the last 15 years, other drugs have been approved in this indication and are widely used in clinical practice at the expense of lithium. New research from the last few years, however, indicates that lithium is still the first-line treatment in this indication. Against this background and lithium's proven acute antimanic efficacy, we should perhaps be using lithium more regularly (in combination with an atypical antipsychotic, if necessary) right from the start for the acute treatment of a manic episode and, once remission has been achieved and euthymia maintained during continuation treatment, to regularly taper off the atypical antipsychotic, if possible, and continue with lithium as monotherapy for prophylactic treatment. This might lead to lithium being used more consistently with the scientific evidence in the long-term treatment of bipolar disorders. It remains uncertain, however, to predict who will respond to and tolerate lithium prophylactically, and more research is needed to deliver the best possible individualized care to our patients. © Georg Thieme Verlag KG Stuttgart · New York.

Recently, an association between childhood growth stunting and aflatoxin (AF) exposure has been identified. In Ghana, homemade nutritional supplements often consist of AF-prone commodities. In this study, children were enrolled in a clinical intervention trial to determine the safety and efficacy of Uniform Particle Size NovaSil (UPSN), a refined calcium montmorillonite known to be safe in adults. Participants ingested 0.75 or 1.5 g UPSN or 1.5 g calcium carbonate placebo per day for 14 days. Hematological and serum biochemistry parameters in the UPSN groups were not significantly different from the placebo-controlled group. Importantly, there were no adverse events attributable to UPSN treatment. A significant reduction in urinary metabolite (AFM1) was observed in the high-dose group compared with placebo. Results indicate that UPSN is safe for children at doses up to 1.5 g/day for a period of 2 weeks and can reduce exposure to AFs, resulting in increased quality and efficacy of contaminated foods.

Limited treatments are available for persistent erythema of rosacea. To examine the long-term safety and efficacy of oxymetazoline cream 1.0% in patients with rosacea with moderate-to-severe persistent erythema. Patients applied oxymetazoline once daily for 52 weeks. Safety assessments included treatment-emergent adverse events (TEAEs), skin blanching, inflammatory lesion counts, telangiectasia, disease severity, and rebound effect. Efficacy was assessed by the Clinician Erythema Assessment and Subject Self-Assessment composite score at 3 and 6 hours after the dose on day 1 and at weeks 4, 26, and 52. Among 440 patients, 8.2% reported treatment-related TEAEs; the most common were application-site dermatitis, paresthesia, pain, and pruritus. The rate of discontinuation due to adverse events (mostly application-site TEAEs) was 3.2%. No clinically meaningful changes were observed in skin blanching, inflammatory lesions, or telangiectasia. At week 52, 36.7%, and 43.4% of patients achieved a 2-grade or greater composite improvement from baseline in both Clinician Erythema Assessment and Subject Self-Assessment 3 and 6 hours after a dose, respectively. Less than 1% of patients experienced a rebound effect following treatment cessation. A vehicle-control group was not included. This long-term study demonstrated sustained safety, tolerability, and efficacy of oxymetazoline for moderate-to-severe persistent erythema of rosacea.

Fingolimod (Gilenya) is an oral medication for patients with highly active relapsing-remitting Multiple Sclerosis (RRMS). Clinical trials and post-marketing experience on more than 114,000 patients have established a detailed safety profile. Total patient exposure now exceeds 195,000 patient-years as stated in the last financial report (Dec 2014) of the Novartis Pharma AG, Basel, Switzerland. However, less is known about the safety of long-term fingolimod use in daily practice. Here, we describe the study design of PANGAEA (Post-Authorization Non-interventional German sAfety of GilEnyA in RRMS patients), a prospective, multicenter, non-interventional, long-term study to collect safety, efficacy, and pharmacoeconomic data on RRMS patients treated with fingolimod (0.5 mg/daily) under real-world conditions in Germany. PANGAEA is striving to assess a real-world safety and efficacy profile of fingolimod, based on data from 4,000 RRMS patients, obtained during a 60-month observational phase. A pharmacoeconomic sub-study of 800 RRMS patients further collects patient-reported outcome measures of disability, quality of life, compliance, treatment satisfaction, and usage of resources during a 24-month observational phase. Descriptive statistical analyses of the safety set as well as of stratified subgroups such as patients with concomitant diabetes mellitus and pretreated patients (e.g., natalizumab) will be conducted. PANGAEA seeks to confirm the current safety profile of fingolimod obtained in phase I-III clinical trials. The study design presented here will additionally provide guidance on the therapeutic use of fingolimod in clinical practice and possibly assists physicians in making evidence-based decisions.

This study proposes and tests a systemic family decision-making framework to understand group long-term care insurance (LTCI) enrollment decisions. A random sample of public employees who were offered group LTCI as a workplace benefit were examined. Findings reveal very good predictive efficacy for the overall conceptual framework with a pseudo R2 value of .687, and reinforced the contributions of factors within the family system. Enrollees were more likely to have discussed the decision with others, used information sources, and had prior experience when compared to non-enrollees. Perceived health status, financial knowledge, attitudes regarding the role of private insurance, risk taking, and coverage features were additional factors related to enrollment decisions. The findings help to inform policymakers about the potential of LTCI as one strategy for financing long-term care.

Morbihan's disease is characterized by chronic persistent facial edema of the upper half of the face, absence of typical diagnostic findings, and refractoriness to treatment. A 44-year-old man was diagnosed with Morbihan's disease based on clinical signs and histopathology, which showed dermal edema in upper dermis, discrete lymphocytic infiltrate without granulomatous reaction, and mast cell infiltration. After long-term therapy with intralesional triamcinolone a remarkable objective and subjective clinical response was observed. Reported cases of Morbihan's disease are reviewed, with respect to their treatment and histopathological findings. Mast cell infiltration has been observed on histopathology in most patients who responded to intralesional triamcinolone, suggesting a possible marker of response. The long-lasting response seen in our case indicates the efficacy of intralesional triamcinolone in this rare condition. © 2018 Wiley Periodicals, Inc.

To evaluate the efficacy and safety of ipragliflozin in real-world clinical practice in Japanese patients with type 2 diabetes. We conducted interim analyses at 3 months of a 3-year prospective study of patients who were first prescribed ipragliflozin between 17 July 2014 and 16 October 2015, and whose data were locked by 16 January 2016. Changes in glycemic control, blood pressure, and laboratory variables from baseline, and incidence of adverse drug reactions (ADRs). Of 11,412 patients initially registered, efficacy and safety data were available for 3481 (30.5%) and 4360 (38.2%) patients, respectively. Hemoglobin A1c and fasting plasma glucose decreased by 0.67% and 28.8 mg/dL, respectively, at 3 months/last assessment (both P < .001) from baseline (8.00% and 166.4 mg/dL, respectively). Blood pressure and lipid levels also improved significantly. There were 258 ADRs in 194 patients. The ADRs included 'renal and urinary disorders' (system organ class) in 110 patients (2.5%). These 3-month interim results indicate that ipragliflozin improved glycemic control, lipids, and blood pressure with low rates of ADRs in Japanese patients with type 2 diabetes in real-world clinical practice. The results were consistent with those of placebo-controlled, randomized clinical trials. Clinicaltrials.gov identifier: NCT02479399.

To evaluate the safety, tolerability, and efficacy of long-term pregabalin as add-on therapy for patients with poorly controlled partial seizures. Analysis of data from six long-term clinical trials involving 2,061 patients receiving open-label pregabalin 75-600 mg/day adjunctive therapy for partial onset epilepsy refractory to multiple antiepileptic drugs. Total pregabalin exposure was 3,877 person-years. The mean duration of pregabalin treatment was 534 days (range 0.3-8 years) and 59% completed 1 year. One-third of patients discontinued for lack of efficacy. The most common dose was >or=300 mg/day; over half took >or=450 mg/day. There was a mean reduction in the 28-day seizure rate of 25-40%, and more than 40% of all patients had a >or=50% reduction in seizures from baseline during the last 3 months of treatment. Twelve percent of all patients had a 6-month period continuously free of seizures. In the last year, 6% were seizure-free for the entire year. Pregabalin was generally well-tolerated and the safety profile favorable in patients treated for up to several years, with an adverse event (AE) profile similar to short-term placebo-controlled trials. Common AEs included CNS symptoms (dizziness, somnolence, headache, and asthenia), accidental injury, and weight gain. CNS AEs tended to be mild and transient. Rates of sudden unexpected death in epilepsy (SUDEP), mortality, cancer, and status epilepticus were within the expected range for this population. Adjunctive pregabalin was effective, generally well tolerated, and safe in the long-term treatment of partial seizures, and provided clinically meaningful seizure reduction and freedom without evidence of tolerance over 2 years of follow-up.

We sought to determine the long-term efficacy, safety, and urodynamic effects of the Mersilene mesh suburethral sling in treating complicated forms of genuine stress incontinence. Two hundred women diagnosed with genuine stress incontinence, complicated by recurrence, intrinsic sphincter deficiency, or chronically increased intraabdominal pressure underwent a suburethral mesh sling procedure (Mersilene; Ethicon Inc, Somerville, NJ). They were monitored with yearly clinical examinations plus short- and long-term postoperative urodynamic evaluations; statistical analysis was carried out by use of the Friedman 2-way analysis by rank, Fischer-Freeman-Halton exact testing, analysis of variance for repeated measures, Wilcoxon, exact Mann-Whitney U test, and Bonferroni paired t test. Of 176 patients who were 5 months or more postop, 127 (72%) had preoperative and short-term postoperative urodynamic evaluations (range 5 to 23 months, mean 12.6 months). Fifty-two of 117 women who were more than 19 months postop (44%) completed preoperative and long-term postoperative urodynamic evaluations at a mean of 63 months (range 20 to 107). One hundred thirty-six of 176 patients (77%) who were more than 4 months postop had a short- and/or long- term postoperative urodynamic evaluation (range 5 to 107 months, mean 30 months). Objective cure rate by stress test was 93% (126 of 136 patients) at a mean of 30 months follow-up. The long-term objective cure rate was 94% (49 of 52). Subjectively, the short- and long-term cure rates were 95.3% and 90.4%, respectively. The cotton swab angle deflection decreased by a mean of 54 degrees at 1 year and 50 degrees at 5 years. Of the 10 failures, the mean preoperative cotton swab straining angle was 19.6 degrees, with 6 being < 30 degrees. Nineteen patients had a negative preoperative cotton swab angle test result (mean straining angle 15 degrees before operation, -6 degrees after operation) and a long-term cure rate of 67%.

A new generation of biologics targeting the interleukin-23-T helper 17 pathway has been developed. This study aimed to assess the short-term effectiveness and safety of these new agents using a network meta-analysis. Twenty-seven randomized clinical trials (10 629 patients) were identified by a comprehensive systematic literature review (PROSPERO 2015: CRD42015025472). Quality of evidence was assessed following Cochrane-compliant rules and the Grading of Recommendations, Assessment, Development and Evaluations approach. Efficacy and safety outcomes at weeks 10-16 were compared using a random-effects network meta-analysis within a frequentist framework to estimate pooled odds ratios (ORs) of direct and indirect comparisons among the therapeutic options. There were six direct drug-to-drug comparisons in the network, with a high degree of consistency between the direct and indirect evidence. From the available evidence, infliximab 5 mg kg -1 every 8 weeks [OR 118·89, 95% confidence interval (CI) 60·91-232·04] and secukinumab 300 mg every 4 weeks (OR 87·07, 95% CI 55·01-137·82) are shown to be among the most effective short-term treatments, but are ranked as the biologics most likely to produce any adverse event or an infectious adverse event, respectively. Ustekinumab 90 mg every 12 weeks, the third most efficacious treatment (OR 73·67, 95% CI 46·97-115·56), was the only agent that did not show increased risk of adverse events compared with placebo. Treatment recommendations should also consider long-term outcomes and costs. © 2016 British Association of Dermatologists.

Stress-related illnesses are a growing health problem in the Western world; which also has economic significance for society. As a consequence; there is a growing demand for effective treatments. The study investigates the long-term efficacy of the Nacadia ® nature-based therapy (NNBT) by comparing it to the efficacy of a validated cognitive behavioral therapy, called STreSS. The study is designed as a randomized controlled trial in which 84 participants are randomly allocated between the treatments. Long-term efficacy is investigated through data extracts from the national database of Statistics Denmark on the sick leave and the health-care consumption. The results show that both the NNBT and the STreSS lead to a significant decrease in number of contacts with a general practitioner in the period from twelve months prior to treatment to twelve months after treatment; and, a significant decrease in long-term sick leave from the month prior to treatment to twelve months after treatment. The positive long-term effects provide validation for the NNBT as an efficient treatment of stress-related illnesses.

Efficacies of roadway safety improvements across functional subclasses of rural two-lane highways.

Labi, Samuel

2011-08-01

Highway crash occurrence is a leading cause of unnatural deaths, and highway agencies continually seek to identify engineering measures to reduce crashes and to assess the efficacy of such measures. Most past studies on the effectiveness of roadway improvements in terms of crash reduction considered all rural two-lane sections as a single category of roads. However, it may be hypothesized that the differences in the mobility and accessibility characteristics that are reflected in (and due to) the different design standards between different functional subclasses in the rural two-lane highway system can lead to differences in efficacies of safety improvements at these subclasses. This paper investigates the efficacy of roadway improvements, in terms of crash reduction, at the various subclasses of rural two-lane highways. An empirical analysis of safety performance at each of the three subclasses of rural two-lane highways was carried out using the negative binomial modeling technique. For each subclass, crash prediction models were developed separately for the three levels of crash severity: property-damage only, injury, and fatal/injury. The crash factors that were considered include lane width, shoulder width, pavement surface friction, pavement condition, and horizontal and vertical alignments. After having developed the safety performance functions, the effectiveness (in terms of the extent of crash reduction, for different levels of crash severity) of highway safety enhancements at each highway subclass were determined using the theoretical concepts established in past literature. These enhancements include widening lanes, widening shoulders, enhancing pavement surface friction, and improving the vertical or horizontal alignment. The study found that there is empirical evidence to justify the decomposition of the family of rural two-lane roads into its constituent subclasses for purposes of analyzing the effectiveness of safety enhancement projects and thus to

This study aimed to investigate the safety and effectiveness of irreversible electroporation ablation for unresectable large liver cancer. Fourteen patients were enrolled: 8 with large hepatocellular carcinoma (tumor diameter: 5.1-11.5 cm) and 6 with medium hepatocellular carcinoma (tumor diameter: 3.0-4.1 cm). All patients received percutaneous irreversible electroporation ablation. Ablation time and the incidence of complications were assessed by a t test. Post-irreversible electroporation and regular contrast-enhanced computerized tomography scans were performed to investigate the effect of tumor size (large vs medium) on irreversible electroporation treatment efficacy; 4-table data were assessed using a Fisher exact test. The 14 patients completed irreversible electroporation ablation successfully. In the large hepatocellular carcinoma group, no major complications occurred in the perioperative period. Minor complications comprised bloating, hypokalemia, edema, low white blood cells, and blood clotting abnormalities. All complications were mild and improved after symptomatic treatment. The frequency of minor complications was not significantly different ( P > .05) compared with the medium hepatocellular carcinoma group. The average follow-up time was 2.8 ± 2.1 months and complete ablation was achieved in 25% (2/8; residual = 75%). For the patients with medium hepatocellular carcinoma, the mean follow-up time was 4.3 ± 3.2 months; the rate of complete ablation was 66.6% (4/6; residual rate = 33.3%). The complete ablation rate was not statistically different between the 2 groups ( P > .05). Irreversible electroporation ablation for unresectable large hepatocellular carcinoma is safe, with no major complications. Short-term efficacy is relatively good; however, long-term efficacy remains to be explored.

The manuscript is one of the series of attempts in authenticating scientific documentation of the seeds of Carica papaya being traditionally used for contraception. To establish safety of the methanol sub-fraction (MSF) of the seeds of Carica papaya as a male contraceptive following long term oral treatment. MSF was administered orally to albino rats at multiples of contraceptive dose (CD) at 50 (1x), 100 (2x), 250 (5x) and 500 (10x)mg/kg body weight daily for 52 weeks. Body weight, organs weight, morbidity, mortality, clinical chemistry, sperm analysis, histopathology and serum testosterone were evaluated to assess the safety and contraceptive efficacy. MSF treatment at various dose regimens, daily for 52 weeks did not show significant changes in body weight, organs weight, food and water intake and pre-terminal deaths compared to those of control animals. Sperm count and viability in 50mg/kg body weight treated animals and the weight of epididymis, seminal vesicle and prostate of all the treated animals showed significant reduction compared to control. Cauda epididymal spermatozoa of 50mg/kg body weight treated animals were immotile. Azoospermia was observed in 100, 250 and 500 mg/kg body weight treated animals. Serum clinical parameters, serum testosterone and histopathology of vital organs were comparable to those of control animals. Histology of testis revealed adverse effects on the process of spermatogenesis, while the histology of epididymis, seminal vesicles and ventral prostate showed no changes compared to control. The long term daily oral administration of MSF affects sperm parameters without adverse side effects and is clinically safe as a male contraceptive. Copyright 2009 Elsevier Ireland Ltd.

The role of low-intensity extracorporeal shock wave therapy (LI-ESWT) in erectile dysfunction (ED) is not clearly determined. The purpose of this study is to investigate the short-term efficacy and safety of LI-ESWT for ED patients. Relevant studies were searched in Medline, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), WANFANG and VIP databases. Effective rate in terms of International Index of Erectile Function-Erectile Function Domain (IIEF-EF) and Erectile Hardness Score (EHS) at about 1month after LI-ESWT was extracted from eligible studies for meta-analysis to calculate risk ratio (RR) of effective treatment in ED patients treated by LI-ESWT compared to those receiving sham-treatment. Overall fifteen studies were included in the review, of which four randomized controlled trials (RCTs) were for meta-analysis. Effective treatment was 8.31 [95% confidence interval (CI): 3.88-17.78] times more effective in the LI-ESWT group (n=176) than in the sham-treatment group (n=101) at about 1 month after the intervention in terms of EHS, while it was 2.50 (95% CI: 0.74-8.45) times more in the treatment group (n=121) than in the control group (n=89) in terms of IIEF-EF. Nine-week protocol with energy density of 0.09mJ/mm2 and 1500 pluses seemed to have better therapeutic effect than five-week protocol. No significant adverse event was reported. LI-ESWT, as a noninvasive treatment, has potential short-term therapeutic effect on patients with organic ED irrespective of sensitivity to PDE5is. Owing to the limited number and quality of the studies, more large-scale, well-designed and long-term follow-up time studies are needed to confirm our analysis.

Increasing evidence from lifetime experimental studies in animals and observational and experimental studies in human subjects suggests that pre- and postnatal nutrition programme long-term health. However, key unanswered questions remain on the extent of early-life programming in contemporary European populations, relevant nutritional exposures, critical time periods, mechanisms and the effectiveness of interventions to prevent or reverse programming effects. The EARly Nutrition programming - long-term Efficacy and Safety Trials and integrated epidemiological, genetic, animal, consumer and economic research (EARNEST) consortium brings together a multi-disciplinary team of scientists from European research institutions in an integrated programme of work that includes experimental studies in human subjects, modern prospective observational studies and mechanistic animal work including physiological studies, cell-culture models and molecular techniques. Theme 1 tests early nutritional programming of disease in human subjects, measuring disease markers in childhood and early adulthood in nineteen randomised controlled trials of nutritional interventions in pregnancy and infancy. Theme 2 examines associations between early nutrition and later outcomes in large modern European population-based prospective studies, with detailed measures of diet in pregnancy and early life. Theme 3 uses animal, cellular and molecular techniques to study lifetime effects of early nutrition. Biomedical studies are complemented by studies of the social and economic importance of programming (themes 4 and 5), and themes encouraging integration, communication, training and wealth creation. The project aims to: help formulate policies on the composition and testing of infant foods; improve the nutritional value of infant formulas; identify interventions to prevent and reverse adverse early nutritional programming. In addition, it has the potential to develop new products through industrial

Two autologous chimeric antigen receptor (CAR) T cell therapies (Kymriah™ and Yescarta™) were recently approved by the FDA. Kymriah™ is for the treatment of pediatric patients and young adults with refractory or relapse (R/R) B cell precursor acute lymphoblastic leukemia and Yescarta™ is for the treatment of adult patients with R/R large B cell lymphoma. In common, both are CD19-specific CAR T cell therapies lysing CD19-positive targets. Their dramatic efficacy in the short term has been highlighted by many media reports. By contrast, their glaring safety gaps behind the miracles remain much less addressed. Here, we focus on addressing the crucial challenges in relation to the gaps. Copyright © 2018 The Authors.

Intervertebral disc degeneration is associated with low-back pain. Mesenchymal stem cells (MSCs) have been used to “regenerate” the disc. The aim of this study was to perform a systematic review of comparative controlled studies that have assessed the safety and efficacy of using MSCs for disc regeneration. Literature databases were extensively searched. Trial design, subject-type, MSC sources, injection method, disc assessment, outcome intervals, and complication events were assessed. Validity of each study was performed. Twenty-four animal studies were included with 20.8% of the studies reporting randomization of groups. Trials in humans fulfilling inclusion criteria were not noted. The studies represented 862 discs that were injected with MSCs and 1,603 discs as controls. All three types of MSCs (ie, bone marrow, synovial, and adipose tissues) showed successful inhibition of disc degeneration. Bone-marrow-derived MSCs demonstrated superior quality of repair compared with other non-MSC treatments. A 2.7% overall complication rate was noted, whereby complications were noted only in rabbits. Overall, evidence suggested that MSCs increased disc space height in the majority of animal models. This is the first systematic review to assess the safety and efficacy of MSCs for the treatment of disc degeneration. Short-term MSC transplantation is safe and effective; however, additional, larger, and higher-quality studies are needed to assess the long-term safety and efficacy. Inconsistencies in methodological design and outcome parameters prevent any robust conclusions. Human-based clinical trials are needed. Recommendations are further made to improve efficacy, reduce potential complications, and standardize techniques for future studies. PMID:25050446

The main objective of the study was to compare the long-term safety and tolerability of fenoterol hydrobromide delivered using a metered-dose inhaler formulated with the alternative propellant, hydrofluoroalkane 134a (HFA-MDI), with delivery using the currently available chlorofluorocarbon MDI (CFC-MDI; Berotec 100). A further objective was to compare the efficacy of fenoterol HFA-MDI with fenoterol CFC-MDI, using the pulmonary function parameters of forced expiratory volume in 1 sec (FEV1), forced vital capacity (FVC) and peak expiratory flow (PEF). Following a 2-week run-in phase, a 12-week, double-blind parallel group comparison was undertaken in 290 patients randomized on a 2:1 basis to two puffs of 100 microg fenoterol four times a day (HFA-MDI=197 patients; CFC-MDI=93 patients). A total of 236 patients in this multi-centre study completed the trial as planned. The overall incidence of adverse events (AEs) was similar in both groups (29.9% of HFA-MDI patients and 28% of CFC-MDI patients). Reports of respiratory disorder AEs were also comparable (21.8% HFA-MDI; 22.6% CFCMDI). End of study laboratory tests, ECG, pulse, blood pressure and physical examination showed no significant differences from pre-study baselines in either group and both treatments appeared to be well tolerated. Pre-dose FEV1 measurements taken at the three clinic visits were constant and increase in FEV1 at 5 and 30 min post-dose demonstrated equivalent efficacy for the two formulations. No difference between the two groups was observed in PEF or in the use of rescue medication. We conclude from these findings that the long-term safety and efficacy profile of fenoterol HFA-MDI is comparable to that of the fenoterol CFC-MDI.

To evaluate the long-term safety and effectiveness of lopinavir/ritonavir (LPV/r) in a population-based cohort of HIV-1-infected children. All children enrolled in the Swiss Mother and Child HIV Cohort Study, treated with LPV/r-based combination antiretroviral treatment (cART) between November 2000 and October 2008, were included. 88 children (25 (28%) protease inhibitor (PI)-naive, 16 (18%) ART-naive) were analysed (251 patient-years on LPV/r). After 48 weeks on LPV/r, 70 children had a median (interquartile range (IQR)) decrease in HIV-1 viral load of 4.25 log (5.45-3.17; PI-naive, n=17) and 2.53 (3.68-1.38; PI-experienced, n=53). Median (IQR) increase in CD4 count was 429 (203-593; PI-naive) and 177 (21-331; PI-experienced) cells/microl. These effects remained stable throughout 192 weeks for 25 children. Treatment was stopped for viral rebound in seven and suspected toxicity in 12 children. Long-term treatment with LPV/r-based cART is safe and effective in HIV-1-infected children.

This study was conducted to assess the acute safety and short term efficacy of renal sympathetic denervation (RSDN) using solid tip radiofrequency ablation (RFA) catheter and saline irrigation through the renal guiding catheter to achieve effective denervation. RSDN using a specialized solid-tip RFA catheter has recently been demonstrated to safely reduce systemic blood pressure in patients with refractory hypertension, the limitation being inadequate power delivery in renal arteries. So, we used solid-tip RFA catheter along with saline irrigation for RSDN. Nine patients with resistant hypertension underwent CT and conventional renal angiography, followed by bilateral or unilateral RSDN using 5F RFA catheter with saline irrigation through renal guiding catheter. Repeat renal angiography was performed at the end of the procedure. In all patients, pre- and post-procedure serum creatinine was measured. Over 1-month period: 1) the systolic/diastolic blood pressure decreased by -57 ± 20/-25 ± 7.5 mm Hg; 2) all patients experienced a decrease in systolic blood pressure of at least -36 mm Hg (range 36-98 mm Hg); 3) there was no evidence of renal artery injury immediate post-procedure. There was no significant change in serum creatinine level. This data shows the acute procedural safety and short term efficacy of RSDN using modified externally irrigated solid tip RFA catheter.

Patients with severe oral lichen planus refractory to standard topical treatment currently have limited options of therapy suitable for long-term use. Oral alitretinoin (9-cis retinoic acid) was never systematically investigated in clinical trials, although case reports suggest its possible efficacy. To assess the efficacy and safety of oral alitretinoin taken at 30 mg once daily for up to 24 weeks in the treatment of severe oral lichen planus refractory to standard topical therapy. We conducted a prospective open-label single arm pilot study to test the efficacy and safety of 30 mg oral alitretinoin once daily for up to 24 weeks in severe oral lichen planus. Ten patients were included in the study. Primary end point was reduction in signs and symptoms measured by the Escudier severity score. Secondary parameters included pain and quality of life scores. Safety parameters were assessed during a follow-up period of 5 weeks. A substantial response at the end of treatment, i.e. >50% reduction in disease severity measured by the Escudier severity score, was apparent in 40% of patients. Therapy was well tolerated. Adverse events were mild and included headache, mucocutaneous dryness, musculoskeletal pain, increased thyroid-stimulating hormone and dyslipidaemia. Alitretinoin given at 30 mg daily reduced disease severity of severe oral lichen planus in a substantial proportion of patients refractory to standard treatment, was well tolerated and may thus represent one therapeutic option for this special group of patients. © 2015 European Academy of Dermatology and Venereology.

To evaluate the safety and efficacy of ab interno trabeculectomy (Trabectome) surgery in Chinese open angle glaucoma patients. Prospective non-comparative case series study. A total of 41 cases (34 primary open angle glaucoma patients, 3 developmental glaucoma patients and 4 pigmentary glaucoma patients) were included in the study. All the cases underwent Trabectome, including 9 cases combined with phacoemulsification cataract extraction. Major outcomes include intraocular pressure (IOP), number of glaucoma medications, secondary glaucoma surgery and postoperative complications. Criteria for successful operation were defined as IOP ≤ 21 mmHg (1 mmHg = 0.133 kPa), at least 20% IOP reduction in any two consecutive visits after 3 months with or without IOP-lowering drugs and no additional glaucoma surgery. IOP and number of glaucoma medications were compared to baseline using Wilcoxon signed-rank test with Bonferroni correction. Kaplan-Meier analysis was performed to analyze the success rate of surgery. In the all 41 patients, 21 cases (51.2%) were followed up for up to 12 months. IOP was reduced from (22.5 ± 8.1) mmHg to (17.6 ± 6.4) mmHg (P = 0.02), meanwhile number of glaucoma medications was reduced from 2.0 ± 0.9 to 1.2 ± 0.9 (P = 0.02) at 12 months. The success rate at one year was 85% and 4 cases required additional glaucoma surgery. Trabectome has many advantages, such as shorter surgery time, simple post-operative care, less intraoperative and postoperative complications and clear IOP-lowering effect. But it slong-term efficacy is still need a large sample, long-term follow-up to verify.

A previously published clinical trial demonstrated the benefit of autologous CD34+ cells transduced with a self-inactivating lentiviral vector (HPV569) containing an engineered β-globin gene (βA-T87Q-globin) in a subject with β-thalassemia major. This vector has been modified to increase transduction efficacy without compromising safety. In vitro analyses indicated that the changes resulted in both increased vector titers (3 to 4 fold) and increased transduction efficacy (2 to 3 fold). An in vivo study in which 58 β-thalassemic mice were transplanted with vector- or mock-transduced syngenic bone marrow cells indicated sustained therapeutic efficacy. Secondary transplantations involving 108 recipients were performed to evaluate long-term safety. The six month study showed no hematological or biochemical toxicity. Integration site (IS) profile revealed an oligo/polyclonal hematopoietic reconstitution in the primary transplants and reduced clonality in secondary transplants. Tumor cells were detected in the secondary transplant mice in all treatment groups (including the control group), without statistical differences in the tumor incidence. Immunohistochemistry and quantitative PCR demonstrated that tumor cells were not derived from transduced donor cells. This comprehensive efficacy and safety data provided the basis for initiating two clinical trials with this second generation vector (BB305) in Europe and in the USA in patients with β-thalassemia major and sickle cell disease.

TAK-085 is an omega-3 preparation that contains eicosapentaenoic acid ethyl-ester (EPA-E) and docosahexaenoic acid-ethyl ester used in the management of hypertriglyceridemia. The aim of the study was to evaluate the long-term safety (adverse events [AEs], laboratory parameters, vital signs, weight, and electrocardiograms) and effects on lipid profiles, especially triglyceride levels, of TAK-085 in Japanese patients with hypertriglyceridemia (triglyceride levels ≥150 mg/dL and <750 mg/dL). In this multicenter, open-label, randomized study, adults with hypertriglyceridemia undergoing lifestyle modification received TAK-085 2 g (2 g once daily; n = 165) or 4 g (2 g twice daily; n = 171), or EPA-E 1.8 g (0.6 g three times daily; n = 167) for 52 weeks. Patients were stratified for co-administration of a statin. TAK-085 was well tolerated throughout the 52-week study. Overall, no substantial differences were found in the tolerability of TAK-085 2 g, TAK-085 4 g, and EPA-E 1.8 g with incidence rates for AEs of 83.6%, 86.0%, and 89.2%, respectively. Most AEs were mild or moderate in severity. Triglyceride levels decreased from baseline in all groups by week 4, and the decreases were maintained throughout the study. At week 52 the reduction in triglycerides with TAK-085 2 g (-13.9%) was similar to that with EPA-E 1.8 g (-12.1%), whereas the reduction seen with TAK-085 4 g (-25.5%) was greater than that with EPA-E 1.8 g, as assessed by point estimates and 95% confidence intervals. TAK-085 was safe and well tolerated for up to 52 weeks of treatment in Japanese patients with hypertriglyceridemia undergoing lifestyle modification. Reductions in triglyceride levels achieved after 4 weeks were maintained at 52 weeks. Copyright © 2013 National Lipid Association. Published by Elsevier Inc. All rights reserved.

To investigate the efficacy, safety, and cost of a pomalidomide-dexamethasone regimen in patients with relapsed and refractory multiple myeloma (RRMM). All patients (n = 63) treated with pomalidomide-dexamethasone for RRMM in our university hospital between August 2013 and October 2015 were included. Pomalidomide was discontinued early due to progression (before the 4th cycle) in 17 (27%) patients. No case was discontinued for intolerance. The only independent factor that predicted early pomalidomide discontinuation was time from diagnosis to pomalidomide initiation <3 years. Overall response rate was 51% including complete response in 8%, very good partial response in 25%, and partial response in 19% patients. Thirteen (33%) patients showed stable disease. Median overall survival was 6.4 months in the 17 patients who discontinued pomalidomide early vs 26.8 months in the 14 patients with stable disease vs not achieved in the 32 responders (log-rank; P < 10 -3 ). The most common grade ≥3 adverse events were neutropenia (14%) and infections (25%). The incremental cost-effectiveness ratio of pomalidomide-dexamethasone compared with dexamethasone alone was estimated at €39 911 per life-year gained. The study demonstrated that pomalidomide-dexamethasone regimen has a long-term favorable safety-efficacy profile in RRMM patients. The survival benefit is substantial even in patients with stable disease. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The orally available BRAF kinase inhibitor vemurafenib is an effective and tolerable treatment option for patients with metastatic melanoma harbouring BRAF V600 mutations. We assessed the safety of vemurafenib in a large population of patients with few alternative treatment options; we report updated 2-year safety. This was an open-label, multicentre study of vemurafenib (960 mg bid) in patients with previously treated or untreated BRAF mutation-positive metastatic melanoma (cobas ® 4800 BRAF V600 Mutation Test). The primary end-point was safety; efficacy end-points were secondary. An exploratory analysis was performed to assess safety outcomes in patients with long duration of response (DOR) (≥12 or ≥24 months). After a median follow-up of 32.2 months (95% CI, 31.1-33.2 months), 3079/3219 patients (96%) had discontinued treatment. Adverse events (AEs) were largely consistent with previous reports; the most common all-grade treatment-related AEs were arthralgia (37%), alopecia (25%) and hyperkeratosis (23%); the most common grade 3/4 treatment-related AEs were squamous cell carcinoma of the skin (8%) and keratoacanthoma (8%). In the exploratory analysis, patients with DOR ≥12 months (n = 287) or ≥24 months (n = 133) were more likely to experience grade 3/4 AEs than the overall population. No new specific safety signals were observed with longer vemurafenib exposure. After 2 years' follow-up, safety was maintained in this large group of patients with BRAF V600 mutation-positive metastatic melanoma who are more representative of routine clinical practice than typical clinical trial populations. These data suggest that long-term vemurafenib treatment is effective and tolerable without the development of new safety signals. Copyright © 2017 Elsevier Ltd. All rights reserved.

Cross-lagged associations between posttraumatic stress symptoms and coping self-efficacy in long-term recovery: A four-wave comparative study.

PubMed

Bosmans, Mark W G; van der Velden, Peter G

2017-11-01

Trauma-related coping self-efficacy (CSE) - in brief, the perceived ability to cope with the aftermath of a traumatic event - has been shown to affect psychological outcomes. A previous study showed that CSE affects subsequent PTSS levels, but not vice versa among a sample exposed 0-6 months ago. In this four-wave follow-up study we examined the cross-lagged relationships between CSE and posttraumatic stress symptoms (PTSS) among those exposed to PTEs (potentially traumatic events) 1-2 years before T1 in order to examine direction of influence. Research questions were: 1) what are the cross-lagged associations between CSE and PTSS levels among those exposed to PTE in the relatively long-term (1-2 years ago, called PTE long-term group), and 2) to what extent do these associations differ from the cross lagged associations among those exposed to PTE in the relatively short-term (0-6 months ago)? Study samples consist of adult respondents of a representative internet panel who experienced a PTE between 1 and 2 years before T1, and did not experience any new PTE between T1 and T3 (long-term group, N = 438) and those exposed in the six months before T1, and not exposed to any additional PTE (short-term group, N = 400). Levels of CSE and PTSS were measured with 4-month intervals. In addition, prospectively assessed personality traits and peritraumatic distress were entered in the analyses. Structural equation modeling showed that CSE perceptions will continue to influence subsequent PTSS levels in the long-term, just as they did in the short-term. Contrary to the more short-term post-exposure period however, CSE levels do not just influence recovery from PTSS. Over time, degree of PTSS experienced also influences subsequent CSE perceptions. Results suggest that while trauma-related CSE perceptions are relatively robust in the short-term recovery period, they can be affected by posttraumatic stress in the long-term.

increasing use reduced the total hospital medical ward expenditure on laxatives from 3788 to 1767 Euros per month. PEG+E is effective in the clinical management of constipation in an institutional setting. Furthermore, long-term intensive therapy with PEG+E was not associated with adverse effects on body weight or blood biochemistry values. Although the time periods over which the economic data and the efficacy and safety data were collected did not directly correspond, this study indicates that use of PEG+E in the management of constipation in people with severe intellectual disability may be cost-effective, reducing hospital laxative costs.

2005-11-01

We performed a prospective, open label study to examine the safety and efficacy of the long-term administration of the tricyclic antidepressant amitriptyline in patients with interstitial cystitis (IC). A total of 94 patients were stratified into 2 groups, namely a National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) group of those who fulfilled NIDDK criteria for IC and a nonNIDDK group of those who presented with characteristic IC symptoms but met at least 1 NIDDK exclusion criterion. Amitriptyline was received strictly at bedtime following an established self-titration protocol without a limitation of the maximum daily dose. Patients reporting improvement in a global response assessment questionnaire were considered treatment responders. Further efficacy measures were changes in pain and urgency, functional bladder capacity and frequency. Changes in the O'Leary-Sant IC index and rating of overall satisfaction with the therapeutic outcome were also reported. Mean study followup +/- SD was 19.0 +/- 12.5 months. The response rate was 64% (60 patients). The overall mean dose was 55 mg (range 12.5 to 150). Side effects occurred in 79 patients (84%), including dry mouth in 79% and weight gain in 59%. Patient overall satisfaction with the therapeutic result was excellent or good in 43 (46%). The dropout rate was 31% (29 patients) after a mean treatment period of 6 weeks at a mean dose of 70 mg. Nonresponse to treatment was the primary reason for dropout in all cases, while side effects contributed to dropout in 25 (86%). Improvement in the various IC symptoms was statistically significant compared with baseline. Long-term administration of amitriptyline is a feasible, safe and effective treatment for IC, provided that the drug is used judiciously to minimize adverse effects. The therapeutic response to amitriptyline was uniformly observed in patients fulfilling NIDDK criteria and in those with the pure clinical diagnosis of IC.

Polycystic ovary syndrome (PCOS) is an endocrinopathy that affects approximately 10% of reproductive-aged women throughout their lives. Women with PCOS present with heterogeneous symptoms including ovulatory dysfunction, hyperandrogenism, and polycystic ovaries. Therefore, lifelong individualized management should be considered. Pharmacological agents commonly used to manage the symptoms are metformin and oral contraceptive pills. Although these medications have been beneficial in treating PCOS symptoms, their efficacy and safety are still not entirely elucidated. This study aimed to report the efficacy and safety of metformin, oral contraceptives, or their combination in the treatment of PCOS and to define their specific individual roles. A literature search of original studies published in PubMed and Scopus was conducted to identify studies comparing metformin with oral contraceptives or evaluating the combination of both in PCOS. Eight clinical trials involving 313 patients were examined in the review. The intervention dosage of metformin ranged from 1,000 to 2,000 mg/d and that of oral contraceptives was ethinylestradiol 35 µg and cyproterone acetate 2 mg. Lower body mass index was observed with regimens including metformin, but increased body mass index was observed in monotherapy with oral contraceptives. Administration of metformin or oral contraceptives, especially as monotherapy, had a negative effect on lipid profiles. In addition, there are still uncertainties surrounding the effects of metformin or oral contraceptives in the management of insulin level, although they improved total testosterone and sex hormone-binding globulin levels. In the included studies, significant side effects due to metformin or oral contraceptives were not reported. The clinical trials suggest that metformin or oral contraceptives are at least patient convenient, efficacious, and safe for the treatment of PCOS. However, well-designed, prospective, long-term, large

Efficacy and safety of acupuncture for chronic dizziness: study protocol for a randomized controlled trial

PubMed Central

2013-01-01

Background Dizziness is one of the most challenging symptoms in medicine. No medication for dizziness in current use has well-established curative or prophylactic value or is suitable for long-term palliative use. Unconventional remedies, such as acupuncture, should be considered and scientifically evaluated. However, there has been relatively little evidence in randomized controlled clinical trials on acupuncture to treat chronic dizziness. The aim of our study is to evaluate the efficacy and safety of acupuncture in patients with dizziness. Methods/Design This trial is a randomized, single-blind, controlled study. A total of 80 participants will be randomly assigned to two treatment groups receiving acupuncture and sham acupuncture treatment, respectively, for 4 weeks. The primary outcome measures are the Dizziness Handicap Inventory (DHI) and the Vertigo Symptom Scale (VSS). Treatment will be conducted over a period of 4 weeks, at a frequency of two sessions per week. The assessment is at baseline (before treatment initiation), 4 weeks after the first acupuncture session, and 8 weeks after the first acupuncture session. Discussion The results from this study will provide clinical evidence on the efficacy and safety of acupuncture in patients with chronic dizziness.

Safinamide is an α-aminoamide with both dopaminergic and non-dopaminergic mechanisms of action in Phase III clinical development as a once-daily add-on to dopamine agonist (DA) therapy for early Parkinson's disease (PD). Study 017 was a 12-month, randomized, double-blind, placebo-controlled pre-planned extension study to the previously reported Study 015. Patients received safinamide 100 or 200 mg/day or placebo added to a single DA in early PD. The primary efficacy endpoint was the time from baseline (Study 015 randomization) to 'intervention', defined as increase in DA dose; addition of another DA, levodopa or other PD treatment; or discontinuation due to lack of efficacy. Safinamide groups were pooled for the primary efficacy endpoint analysis; post hoc analyses were performed on each separate dose group. Of the 269 patients randomized in Study 015, 227 (84%) enrolled in Study 017 and 187/227 (82%) patients completed the extension study. Median time to intervention was 559 and 466 days in the pooled safinamide and placebo groups, respectively (log-rank test; P = 0.3342). In post hoc analyses, patients receiving safinamide 100 mg/day experienced a significantly lower rate of intervention compared with placebo (25% vs. 51%, respectively) and a delay in median time to intervention of 9 days (P < 0.05; 240- to 540-day analysis). The pooled data from the safinamide groups failed to reach statistical significance for the primary endpoint of median time from baseline to additional drug intervention. Post hoc analyses indicate that safinamide 100 mg/day may be effective as add-on treatment to DA in PD. © 2012 The Author(s) European Journal of Neurology © 2012 EFNS.

Long-term (5 years), high daily dosage of dietary agmatine--evidence of safety: a case report.

There is presently a great interest in the therapeutic potential of agmatine, decarboxylated arginine, for various diseases. Recent clinical studies have already shown that oral agmatine sulfate given for up to 3 weeks provides a safe and, as compared with current therapeutics, more effective treatment for neuropathic pain. These studies have ushered in the use of dietary agmatine as a nutraceutical. However, in view of information paucity, assessment of long-term safety of oral agmatine treatment is now clearly required. The authors of this report undertook to assess their own health status during ongoing consumption of a high daily dosage of oral agmatine over a period of 4-5 years. A daily dose of 2.67 g agmatine sulfate was encapsulated in gelatin capsules; the regimen consists of six capsules daily, each containing 445 mg, three in the morning and three in the evening after meals. Clinical follow-up consists of periodic physical examinations and laboratory blood and urine analyses. All measurements thus far remain within normal values and good general health status is sustained throughout the study period, up to 5 years. This case study shows for the first time that the recommended high dosage of agmatine may be consumed for at least 5 years without evidence of any adverse effects. These initial findings are highly important as they provide significant evidence for the extended long-term safety of a high daily dosage of dietary agmatine--a cardinal advantage for its utility as a nutraceutical.

This article summarizes the recommendations on data and methodology issues for studying commercial motor vehicle driver fatigue of a National Academies of Sciences, Engineering, and Medicine study. A framework is provided that identifies the various factors affecting driver fatigue and relating driver fatigue to crash risk and long-term driver health. The relevant factors include characteristics of the driver, vehicle, carrier and environment. Limitations of existing data are considered and potential sources of additional data described. Statistical methods that can be used to improve understanding of the relevant relationships from observational data are also described. The recommendations for enhanced data collection and the use of modern statistical methods for causal inference have the potential to enhance our understanding of the relationship of fatigue to highway safety and to long-term driver health.

Safety and Efficacy of Neonatal Vaccination

PubMed Central

Demirjian, Alicia; Levy, Ofer

2009-01-01

Newborns have an immature immune system that renders them at high risk for infection while simultaneously reducing responses to most vaccines, thereby posing challenges in protecting this vulnerable population. Nevertheless, certain vaccines, such as Bacillus Calmette Guérin (BCG) and Hepatitis B vaccine (HBV), do demonstrate safety and some efficacy at birth, providing proof of principal that certain antigen-adjuvant combinations are able to elicit protective neonatal responses. Moreover, birth is a major point of healthcare contact globally meaning that effective neonatal vaccines achieve high population penetration. Given the potentially significant benefit of vaccinating at birth, availability of a broader range of more effective neonatal vaccines is an unmet medical need and a public health priority. This review focuses on safety and efficacy of neonatal vaccination in humans as well as recent research employing novel approaches to enhance the efficacy of neonatal vaccination. PMID:19089811

The dual SRC/ABL1 tyrosine kinase inhibitor bosutinib is indicated for adults with Ph+ chronic myeloid leukaemia (CML) resistant/intolerant to prior therapy. This analysis of an ongoing phase 1/2 study (NCT00261846) assessed effects of baseline patient characteristics on long-term efficacy and safety of bosutinib 500 mg/day in adults with imatinib (IM)-resistant (IM-R; n = 196)/IM-intolerant (IM-I; n = 90) chronic phase (CP) CML. Median treatment duration was 24·8 months (median follow-up, 43·6 months). Cumulative major cytogenetic response (MCyR) rate [95% confidence interval (CI)], was 59% (53-65%); Kaplan-Meier (KM) probability of maintaining MCyR at 4 years was 75% (66-81%). Cumulative incidence of on-treatment progression/death at 4 years was 19% (95% CI, 15-24%); KM 2-year overall survival was 91% (87-94%). Significant baseline predictors of both MCyR and complete cytogenetic response (newly attained/maintained from baseline) at 3 and 6 months included prior IM cytogenetic response, baseline MCyR, prior interferon therapy and <6 months duration from diagnosis to IM treatment initiation and no interferon treatment before IM. The most common adverse event (AE) was diarrhoea (86%). Baseline bosutinib-sensitive BCR-ABL1 mutation was the only significant predictor of grade 3/4 diarrhoea; no significant predictors were identified for liver-related AEs. Bosutinib demonstrates durable efficacy and manageable toxicity in IM-R/IM-I CP-CML patients. © 2015 The Authors. British Journal of Haematology published by John Wiley & Sons Ltd.

To evaluate the long-term safety of rituximab (RTX) in rheumatoid arthritis (RA) patients in daily clinical practice. This was a multicentre (17 Greek Rheumatology sites), prospective, long-term, pharmacovigilance study of patients with moderate to severe RA and an inadequate response or intolerance to ≥1 anti-tumour necrosis factor (TNF) agents. Adverse events (AEs) were recorded and collected prospectively every 2-6 months. 234 patients (mean age: 59±12.5, 79.5% women, mean DAS28: 5.35±1.32) were included and followed for 27.7 months (median). The overall AEs, serious AE (SAEs) and serious infection (SIEs) rate were 48.36, 6.68 and 2.53/100 patient-years, respectively. Three cases of hepatitis B virus (HBV) reactivation were recorded (two in chronic and one in past HBV infection). Withdrawals due to AEs (5.6%) occurred more frequently during the first cycles of RTX therapy while repeated RTX cycles were not associated with an increased risk of AEs. There were 3 deaths with an incidence rate of 0.69/100 patient-years. Age ≥65 years was associated with a higher incidence rate ratio of AEs and SAEs as compared to <65 years (1.53, p=0.002 and 2.88, p=0.005, respectively). Drug retention rate during 434.28 patient-years of follow-up was 57.3%. Factors associated with drug discontinuation by multivariate analysis included age, baseline swollen joint count and no use of concomitant methotrexate therapy. Long-term RTX therapy in a real-life RA cohort, did not reveal any new safety issues. Advanced age was associated with increased risk of AEs and premature drug discontinuation.

In the PROTECT AF (Watchman Left Atrial Appendage Closure Technology for Embolic Protection in Patients With Atrial Fibrillation) trial that evaluated patients with nonvalvular atrial fibrillation (NVAF), left atrial appendage (LAA) occlusion was noninferior to warfarin for stroke prevention, but a periprocedural safety hazard was identified. The goal of this study was to assess the safety and efficacy of LAA occlusion for stroke prevention in patients with NVAF compared with long-term warfarin therapy. This randomized trial further assessed the efficacy and safety of the Watchman device. Patients with NVAF who had a CHADS2 (congestive heart failure, hypertension, age >75 years, diabetes mellitus, and previous stroke/transient ischemic attack) score ≥2 or 1 and another risk factor were eligible. Patients were randomly assigned (in a 2:1 ratio) to undergo LAA occlusion and subsequent discontinuation of warfarin (intervention group, n = 269) or receive chronic warfarin therapy (control group, n = 138). Two efficacy and 1 safety coprimary endpoints were assessed. At 18 months, the rate of the first coprimary efficacy endpoint (composite of stroke, systemic embolism [SE], and cardiovascular/unexplained death) was 0.064 in the device group versus 0.063 in the control group (rate ratio 1.07 [95% credible interval (CrI): 0.57 to 1.89]) and did not achieve the prespecified criteria noninferiority (upper boundary of 95% CrI ≥1.75). The rate for the second coprimary efficacy endpoint (stroke or SE >7 days' postrandomization) was 0.0253 versus 0.0200 (risk difference 0.0053 [95% CrI: -0.0190 to 0.0273]), achieving noninferiority. Early safety events occurred in 2.2% of the Watchman arm, significantly lower than in PROTECT AF, satisfying the pre-specified safety performance goal. Using a broader, more inclusive definition of adverse effects, these still were lower in PREVAIL (Watchman LAA Closure Device in Patients With Atrial Fibrillation Versus Long Term Warfarin Therapy

Growth hormone (GH) is the most frequently used treatment in children with idiopathic short stature (ISS). Aromatase inhibitor (AI) therapy is still in an experimental state, and both final height (FH) and long-term efficacy data in ISS have not been published. We present a 14.5-year-old boy with ISS and a height of 142.7 cm [standard deviation score (SDS) -2.79]. Based on the baseline bone age (BA) of 13.5-14 years, his predicted adult height (PAH) by Bayley/Pinneau was 154 cm (SDS -3.77)-158.2 (SDS -3.15). After a 5-year letrozole monotherapy, FH was 169 cm (SDS -1.57) showing a height difference between PAH and FH from 10.8 to 15 cm. No permanent side effects of the medication have been observed. Both a transient occurrence and a spontaneous recovery of decreased bone mineral apparent density were seen, verified by dual-energy X-ray absorptiometry. Spinal magnetic resonance imaging revealed no vertebral abnormalities. All therapy might be an effective and low-cost alternative to the use of GH. Further controlled trials should prove efficacy and safety of long-term AI therapy in boys with ISS.

To study whether serum levels of tumour necrosis factor-α (TNF-α), free or bound to etanercept, in biological-naïve adults with rheumatoid arthritis (RA) could predict the long-term efficacy of etanercept, measured as drug survival. We identified 145 biological-naïve patients with RA starting treatment with etanercept at the Department of Rheumatology, Skåne University Hospital (1999-2008), of whom 16 had seronegative and 129 seropositive RA. TNF-α in serum was quantified using enzyme-linked immunosorbent assay in samples from the onset of treatment and at 6 week follow-up. Drug survival time was used to evaluate the long-term efficacy of etanercept. Levels of TNF-α were significantly increased at follow-up compared to at the start. At the 6 week follow-up, circulating TNF-α mainly comprised TNF-α in complex with etanercept. Longer drug survival time correlated with increased TNF-α at 6 week follow-up in the patients with seronegative RA, but not in the seropositive patients. We demonstrated that levels of circulating TNF-α increased in almost all individuals after initiation of treatment with etanercept and that this increase mainly comprised TNF-α in complex with etanercept. More importantly, this increase may predict drug survival in adults with seronegative, but not seropositive, RA and suggests that measuring TNF-α/etanercept complexes in serum may be relevant in patients with seronegative RA.

The objective of this study is to assess the efficacy and safety of miconazole for treating oral candidiasis. Twelve electronic databases were searched for randomized controlled trials evaluating treatments for oral candidiasis and complemented by hand searching. The clinical and mycological outcomes, as well as adverse effects, were set as the primary outcome criteria. Seventeen trials were included in this review. Most studies were considered to have a high or moderate level of bias. Miconazole was more effective than nystatin for thrush. For HIV-infected patients, there was no significant difference in the efficacy between miconazole and other antifungals. For denture wearers, microwave therapy was significantly better than miconazole. No significant difference was found in the safety evaluation between miconazole and other treatments. The relapse rate of miconazole oral gel may be lower than that of other formulations. This systematic review and meta-analysis indicated that miconazole may be an optional choice for thrush. Microwave therapy could be an effective adjunct treatment for denture stomatitis. Miconazole oral gel may be more effective than other formulations with regard to long-term results. However, future studies that are adequately powered, large-scale, and well-designed are needed to provide higher-quality evidence for the management of oral candidiasis. © 2015 John Wiley & Sons A/S.

To investigate and compare the long-term safety, efficacy, and accuracy of PRK (photorefractive keratectomy) and LASEK (laser epithelial keratomileusis) in myopic corneas having residual corneal thickness less than 400 micron meters (µm). The medical reports of the patients who had undergone excimer laser surface ablation between 2007-2011 and had a residual corneal thickness less than 400 µm were retrospectively reviewed. Forty-two eyes of 42 patients with a mean age of 28.79±7.76 years were enrolled into the study. Twenty-two PRK and 20 LASEK procedures were performed. The mean follow-up time was 45.00±11.80 months. At the end of follow-up, no ectasia was detected. Nineteen percent of eyes had trace haze. No eyes lost any lines in corrected distance visual acuity. Eighty-one percent of the patients had an uncorrected distance visual acuity better than 20/40. The regression rate was 16.7%. Sixty-two percent of eyes were within ±1.00 D. The safety and efficacy indexes were 1.19±0.42 and 1.00±0.40, respectively. There was not any difference between LASEK and PRK regarding achieved spherical equivalent refraction, haze ratio, visual acuity, safety, efficacy, and regression. Both PRK and LASEK are safe and effective in myopic corneas having thin residual thickness.

Severe pulmonary hypertension is a progressive disease which leads to limitations of functional status and poor survival. We evaluated efficacy and safety of a short (3 months) and a long term (12 months) sildenafil treatment in patients with severe pulmonary hypertension. We treated 12 patients with pulmonary hypertension with oral sildenafil. Patients were followed at three time points, at baseline, and after 3 and 12 months of treatment. Primary end point was improvement in functional exercise capacity assesed by 6-minute walk test, and secondary end points were changes in right ventricle hemodynamics. We found significant improvement in 6-minute walk test distance from 357 +/- 193 m at baseline to 431 +/- 179 m after three months and further improvement to 501 +/- 159 m after 12 months (p < 0.01); decrease in right ventricule pressure from 107 +/- 42 mmHg at baseline to 87 +/- 32 mmHg after 12 months (p < 0.01); and, decrease in right ventricule diameter from 3.2 +/- 1.1 cm to 2.76 +/- 0.86 cm after twelve months (p < 0.01). Drug-related adverse events were mild and transient in our group of patients. Long-term (12 months) sildenafil treatment is effective and safe in our patients with idiopathic and chronic thrombo-embolic pulmonary hypertension.

Objectives : Antimicrobial therapy is one of the cornerstones of orthopaedic implant-related infections (OIRI) treatment. Infections with Gram-positive bacteria are often treated with vancomycin, penicillin or clindamycin. A recent IDSA guideline suggests increasing the dose of vancomycin to increase the trough vancomycin target serum concentrations. This is deemed necessary because of an observed decrease in vancomycin susceptibility among Gram-positive bacteria. However, elevated vancomycin concentrations are correlated with the risk of nephrotoxicity, especially with prolonged therapy. Compared to most countries, rates of resistance against antibiotics among bacteria in the Netherlands are lower for currently available antibiotics, therefore lower target concentrations of vancomycin are probably efficacious for the treatment of infections. In this study we evaluated the efficacy and safety of long-term conventionally dosed vancomycin therapy, as an initial therapy for OIRI, and compared this with long-term penicillin and clindamycin therapy, as initial therapy, in patients with Gram-positive orthopaedic implant-related infections. Methods : A retrospective, observational study was conducted in 103 adult patients treated for OIRI, with vancomycin, penicillin or clindamycin for at least 10 days. The target trough serum concentration of vancomycin was 10-15 mg/l. Results : 74% of our patients were treated successfully with vancomycin, as initial therapy, (no reinfection within 1 year) versus 55% of our patients treated with either an antibiotic of the penicillin class (mostly flucloxacillin) or clindamycin (p=0.08), as initial therapy. For patients treated with vancomycin we observed a serum creatinine increase of 6 μmol/l, for patients treated with either an antibiotic of the penicillin class or clindamycin the serum creatinine increase was 4 μmol/l (p=0.395). Conclusions : In our population of patients with OIRI long-term treatment with conventionally dosed

HPV-023 (NCT00518336; ClinicalTrial.gov) is a long-term follow-up of an initial double-blind, randomized (1:1), placebo-controlled study (HPV-001, NCT00689741) evaluating the efficacy against human papillomavirus (HPV)-16/18 infection and associated cyto-histopathological abnormalities, persistence of immunogenicity, and safety of the HPV-16/18 AS04-adjuvanted vaccine. Among the women, aged 15–25 years, enrolled in HPV-001 and who participated in the follow-up study HPV-007 (NCT00120848), a subset of 437 women from five Brazilian centers participated in this 36-month long-term follow-up (HPV-023) for a total of 113 months (9.4 years). During HPV-023, anti-HPV-16/18 antibodies were measured annually by enzyme-linked immunosorbent assay (ELISA) and pseudovirion-based neutralisation assay (PBNA). Cervical samples were tested for HPV DNA every 6 months, and cyto-pathological examinations were performed annually. During HPV-023, no new HPV-16/18-associated infections and cyto-histopathological abnormalities occurred in the vaccine group. Vaccine efficacy (VE) against HPV-16/18 incident infection was 100% (95%CI: 66.1, 100). Over the 113 months (9.4 years), VE was 95.6% (86.2, 99.1; 3/50 cases in vaccine and placebo groups, respectively) against incident infection, 100% (84·1, 100; 0/21) against 6-month persistent infection (PI); 100% (61·4, 100; 0/10) against 12-month PI; 97·1% (82.5, 99.9; 1/30) against ≥ ASC-US; 95·0% (68.0, 99.9; 1/18) against ≥ LSIL; 100% (45.2, 100; 0/8) against CIN1+; and 100% (–128.1, 100; 0/3) against CIN2+ associated with HPV-16/18. All vaccinees remained seropositive to HPV-16/18, with antibody titers remaining several folds above natural infection levels, as measured by ELISA and PBNA. There were no safety concerns. To date, these data represent the longest follow-up reported for a licensed HPV vaccine. PMID:25424918

Convection-enhanced delivery (CED) is gaining popularity in direct brain infusions. Our group has pioneered the use of liposomes loaded with the MRI contrast reagent as a means to track and quantitate CED in the primate brain through real-time MRI. When co-infused with therapeutic nanoparticles, these tracking liposomes provide us with unprecedented precision in the management of infusions into discrete brain regions. In order to translate real-time CED into clinical application, several important parameters must be defined. In this study, we have analyzed all our cumulative animal data to answer a number of questions as to whether real-time CED in primates depends on concentration of infusate, is reproducible, allows prediction of distribution in a given anatomic structure, and whether it has long term pathological consequences. Our retrospective analysis indicates that real-time CED is highly predictable; repeated procedures yielded identical results, and no long-term brain pathologies were found. We conclude that introduction of our technique to clinical application would enhance accuracy and patient safety when compared to current non-monitored delivery trials.

tolerability data were observed between the belimumab and placebo groups. No differences were observed between the rituximab and placebo groups for the efficacy outcomes or safety parameters. Extracted data from the 13 studies were pooled, allowing assessment of the safety of biologic drugs. The meta-analysis revealed a satisfactory safety profile of these agents when used for SLE treatment, as there were no significant differences between the two evaluated groups (biologic agents and placebo) for all outcomes analyzed. Belimumab exhibited a satisfactory profile regarding efficacy, safety, and tolerability. Rituximab showed no superiority over placebo in terms of efficacy, despite its suitable safety profile. Biologic agents exhibited a good safety profile for SLE treatment, indicating that these agents are promising therapies and should be further investigated.

Long-term modifications of synaptic efficacy in the human inferior and middle temporal cortex

The primate temporal cortex has been demonstrated to play an important role in visual memory and pattern recognition. It is of particular interest to investigate whether activity-dependent modification of synaptic efficacy, a presumptive mechanism for learning and memory, is present in this cortical region. Here we address this issue by examining the induction of synaptic plasticity in surgically resected human inferior and middle temporal cortex. The results show that synaptic strength in the human temporal cortex could undergo bidirectional modifications, depending on the pattern of conditioning stimulation. High frequency stimulation (100 or 40 Hz) in layer IV induced long-term potentiation (LTP) of both intracellular excitatory postsynaptic potentials and evoked field potentials in layers II/III. The LTP induced by 100 Hz tetanus was blocked by 50-100 microM DL-2-amino-5-phosphonovaleric acid, suggesting that N-methyl-D-aspartate receptors were responsible for its induction. Long-term depression (LTD) was elicited by prolonged low frequency stimulation (1 Hz, 15 min). It was reduced, but not completely blocked, by DL-2-amino-5-phosphonovaleric acid, implying that some other mechanisms in addition to N-methyl-DL-aspartate receptors were involved in LTD induction. LTD was input-specific, i.e., low frequency stimulation of one pathway produced LTD of synaptic transmission in that pathway only. Finally, the LTP and LTD could reverse each other, suggesting that they can act cooperatively to modify the functional state of cortical network. These results suggest that LTP and LTD are possible mechanisms for the visual memory and pattern recognition functions performed in the human temporal cortex.

To evaluate the efficacy and safety of elagolix, an oral, nonpeptide gonadotropin-releasing hormone antagonist, over 12 months in women with endometriosis-associated pain. Elaris Endometriosis (EM)-III and -IV were extension studies that evaluated an additional 6 months of treatment after two 6-month, double-blind, placebo-controlled phase 3 trials (12 continuous treatment months) with two elagolix doses (150 mg once daily and 200 mg twice daily). Coprimary efficacy endpoints were the proportion of responders (clinically meaningful pain reduction and stable or decreased rescue analgesic use) based on average monthly dysmenorrhea and nonmenstrual pelvic pain scores. Safety assessments included adverse events, clinical laboratory tests, and endometrial and bone mineral density assessments. The power of Elaris EM-III and -IV was based on the comparison to placebo in Elaris EM-I and -II with an expected 25% dropout rate. Between December 28, 2012, and October 31, 2014 (Elaris EM-III), and between May 27, 2014, and January 6, 2016 (Elaris EM-IV), 569 participants were enrolled. After 12 months of treatment, Elaris EM-III responder rates for dysmenorrhea were 52.1% at 150 mg once daily (Elaris EM-IV=50.8%) and 78.1% at 200 mg twice daily (Elaris EM-IV=75.9%). Elaris EM-III nonmenstrual pelvic pain responder rates were 67.8% at 150 mg once daily (Elaris EM-IV=66.4%) and 69.1% at 200 mg twice daily (Elaris EM-IV=67.2%). After 12 months of treatment, Elaris EM-III dyspareunia responder rates were 45.2% at 150 mg once daily (Elaris EM-IV=45.9%) and 60.0% at 200 mg twice daily (Elaris EM-IV=58.1%). Hot flush was the most common adverse event. Decreases from baseline in bone mineral density and increases from baseline in lipids were observed after 12 months of treatment. There were no adverse endometrial findings. Long-term elagolix treatment provided sustained reductions in dysmenorrhea, nonmenstrual pelvic pain, and dyspareunia. The safety was consistent with reduced

Lipoprotein (a) [Lp (a)] is a well-established risk factor for coronary artery disease (CAD). However, up till now, treatment of patients with higher Lp (a) levels is challenging. This current study aimed to investigate the therapeutic effects of short-, medium and long-term statin use on the Lp (a) reduction and its modifying factors. The therapeutic duration was categorized into short-term (median, 39 days), medium term (median, 219 days) and long-term (median, 677 days). The lipid profiles before therapy served as baselines. Patients at short-, medium or long-term exactly matched with those at baseline. Every patient's lipid profiles during the follow-ups were compared to his own ones at baselines. The current study demonstrated that long-term statin therapy significantly decreased the Lp (a) levels in CAD patients while short-term or medium term statin therapy didn't. When grouped by statin use, only long-term simvastatin use significantly decreased the Lp (a) levels while long-term atorvastatin use insignificantly decreased the Lp (a) levels. Primary hypertension (PH), DM, low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C) could modify the therapeutic effects of statin use on the Lp (a) levels in CAD patients. The long-term statin therapy could be efficacious in reducing the Lp (a) levels in CAD patients, which has been modified by some traditional risk factors. In the era of commercial unavailability of more reliable Lp (a) lowering drugs, our findings will bolster confidence in fighting higher Lp (a) abnormalities both for patients and for doctors.

Abstract Background: Drug intensification is often required for patients with type 2 diabetes mellitus on stable metformin therapy. Among the potential candidates for a combination therapy, sodium-glucose transporter-2 (SGLT2) inhibitors have shown promising outcomes. This meta-analysis was performed to compare the efficacy and safety of SGLT2 inhibitors with non-SGLT2 combinations as add-on treatment to metformin. Methods: Literature search was carried out in multiple electronic databases for the acquisition of relevant randomized controlled trials (RCTs) by following a priori eligibility criteria. After the assessment of quality of the included RCTs, meta-analyses of mean differences or odds ratios (OR) were performed to achieve overall effect sizes of the changes from baseline in selected efficacy and safety endpoints reported in the individual studies. Between-studies heterogeneity was estimated with between-studies statistical heterogeneity (I2) index. Results: Six RCTs fulfilled the eligibility criteria. SGLT2 inhibitors as add-on to metformin treatment reduced % HbA1c significantly more than non-SGLT2 combinations after 52 weeks (P = .002) as well as after 104 weeks (P < .00001). Among other endpoints, SGLT2 inhibitors also reduced fasting plasma glucose levels, body weight, systolic, and diastolic blood pressures after 52 weeks and 104 weeks significantly (P < .00001) more than non-SGLT2 combinations. Incidence of hypoglycemia was significantly lower (P = .02) but incidence of suspected or confirmed genital tract infections was significantly higher (P < .00001) in SGLT2 inhibitors treated in comparison with non-SGLT2 combinations. Conclusion: As add-on to metformin treatment, SGLT2 inhibitors are found significantly more efficacious than non-SGLT2 inhibitor combinations in the management of type 2 diabetes mellitus, although, SGLT2 inhibitor therapy is associated with significantly higher incidence of suspected or confirmed genital tract

Deferasirox is a novel once-daily, oral iron chelator. The aim of this study was to evaluate the long-term efficacy and tolerability of deferasirox in Taiwanese patients with transfusion-dependent β-thalassemia who have been treated with deferasirox for 7 years. Taiwanese patients aged ≥2 years with transfusion-dependent β-thalassemia whose serum ferritin levels were ≥1000 ng/mL and had started deferasirox treatment since December 2005 at the National Taiwan University Hospital were enrolled. Sixty patients were recruited for analysis, and 11 (18.3 %) patients discontinued deferasirox during the study. In the 42 patients included in the efficacy analysis, the mean serum ferritin levels decreased significantly by 2566 ng/mL after 7 years of treatment (P < 0.001). Forty-one of these patients received a cardiac T2* evaluation after 3 years of deferasirox treatment, and the mean cardiac T2* value increased significantly from 30.6 ± 16.6 to 45.9 ± 22.6 ms after 7 years of deferasirox treatment (P < 0.001). Deferasirox-related adverse events assessed by investigators were reported in 46 (76.7 %) patients. The most common adverse events related to deferasirox were skin rashes (n = 29, 48.3 %), followed by abdominal pain (n = 23, 38.3 %) and diarrhea (n = 16, 26.7 %). Most adverse events were manageable. This study demonstrated that long-term treatment with deferasirox was effective in improving iron overload, including cardiac iron overload, in patients with transfusion-dependent β-thalassemia. Deferasirox was well tolerated; however, the incidences of common adverse events related to deferasirox appeared higher in our Taiwanese patients than other studies.

The study aimed to evaluate the long-term efficacy of treatment with extract of Serenoa repens (Prostamol Uno) in patients with lower urinary tract symptoms (LUTS) induced by benign prostatic hyperplasia (BPH). We studied 120 patients with mild or moderate LUTS induced by BPH, maximal urinary flow (Q(max)) <15 ml with a voided volume ≥150 ml, prostate-specific antigen <4 ng/ml, and residual urinary volume <150 ml, treated daily for 24 months with one capsule of 320 mg ethanolic extract of Serenoa repens. Statistically significant improvements in the International Prostate Symptom Score (5.5 points), quality of life (QoL; 1.8 points), Q(max) (5.6 ml/s), International Index of Erectile Function (IIEF; 6.4 points) and reduction in residual urinary volume were observed during the study period. The mean prostate volume at 24 months was 36 ml, compared to 39.8 ml at baseline. Long-term treatment with 320 mg ethanolic extract of Serenoa repens proved to be efficient in reducing urinary obstruction, improving symptomatology and QoL of BPH patients. It also had a positive effect on sexual function, demonstrated by the statistically significant increase in the IIEF. Copyright © 2011 S. Karger AG, Basel.

Intensive treatment including surgery for patients with trisomy 13 (T13) remains controversial. This study aimed to evaluate the safety and efficacy of noncardiac surgical intervention for T13 patients. Medical records of patients with karyotypically confirmed T13 treated in the neonatal intensive care unit in Nagano Children's Hospital from January 2000 to October 2016 were retrospectively reviewed, and data from patients who underwent noncardiac surgery were analyzed. Of the 20 patients with T13, 15 (75%) underwent a total of 31 surgical procedures comprising 15 types, including tracheostomy in 10 patients and gastrostomy in 4. Operative time, anesthesia time, and amount of bleeding are described for the first time in a group of children with T13. All the procedures were completed safely with no anesthetic complications or surgery-related death. The overall rate of postoperative complications was 19.3%. Patients receiving tracheostomy had stable or improved respiratory condition. Six of them were discharged home and were alive at the time of this study. These results suggest at least short-term safety and efficacy of major noncardiac surgical procedures, and long-term efficacy of tracheostomy on survival or respiratory stabilization for home medical care of children with T13. Noncardiac surgical intervention is a reasonable choice for patients with T13. © 2018 Wiley Periodicals, Inc.

Non-invasive ventilation (NIV) is recognized as first line therapy in acute hypercapnic respiratory failure and chronic alveolar hypoventilation caused by several diseases (restrictive thoracic disorders, neuromuscular disease and obesity-hypoventilation syndrome). In Switzerland and other European countries, long-term NIV has also been applied in hypercapnic patients with chronic obstructive pulmonary disease (COPD). However, only recently has conclusive evidence showing benefits of long-term NIV become available. Long-term NIV in COPD has now shown its efficacy in many studies. However, despite these findings, indications, ventilatory settings and monitoring remain poorly known and topic of debate.

In Australia, there is an unmet need for improved treatments for rheumatoid arthritis (RA). Tofacitinib is an oral Janus kinase inhibitor for the treatment of RA. To provide an overview of key study outcomes for tofacitinib in Australian patients, we analyzed the efficacy and safety of tofacitinib in the Australian subpopulation of global RA phase III and long-term extension (LTE) studies. Data were pooled from the Australian subpopulation of four phase III studies and one LTE study (database not locked at cut-off date: January 2016). Patients in the phase III studies received tofacitinib 5 or 10 mg twice daily (BID), placebo (advancing to tofacitinib at months 3 or 6), or adalimumab, with background methotrexate or conventional synthetic disease-modifying antirheumatic drugs. Patients in the LTE study received tofacitinib 5 or 10 mg BID. Efficacy endpoints were American College of Rheumatology (ACR) 20/50/70 response rates, and change from baseline in the Disease Activity Score in 28 joints, erythrocyte sedimentation rate [DAS28-4(ESR)] and Health Assessment Questionnaire-Disability Index (HAQ-DI) scores. Safety endpoints included incidence of adverse events (AEs), serious AEs, and discontinuations due to AEs. AEs of special interest and laboratory parameters were analyzed in the LTE study. Across phase III studies (N = 100), ACR response rates and improvements in DAS28-4(ESR) and HAQ-DI scores were numerically greater with tofacitinib vs. placebo at month 3, and increased until month 12. The results were sustained in the LTE study (N = 99) after 60 months' observation. In general, the efficacy and safety profiles of tofacitinib were similar to those of the global RA population. In Australian patients with RA, tofacitinib therapy demonstrated sustained efficacy and consistent safety over ≥ 60 months' treatment. Pfizer Inc.

In previous studies, itraconazole was revealed to be an effective therapy and was considered to be the gold standard treatment for mild-to-moderate acute and chronic clinical forms of paracoccidioidomycosis. A pilot study was conducted to investigate the efficacy, safety, and tolerability of voriconazole for the long-term treatment of acute or chronic paracoccidioidomycosis, with itraconazole as the control treatment. A randomized, open-label study was conducted at 3 Brazilian tertiary care hospitals. Patients were randomized (at a 2 : 1 ratio) to receive oral therapy with voriconazole or itraconazole for 6 months. Patients receiving >or=1 dose of study drug were evaluated for safety; patients with confirmed paracoccidioidomycosis who completed >or=6 months of therapy (treatment-evaluable patients) were evaluated for treatment efficacy. Satisfactory global response was assessed at the end of treatment. Fifty-three patients were evaluated for treatment safety (35 received voriconazole, and 18 received itraconazole). Both drugs were well tolerated. The most common treatment-related adverse events in the voriconazole group included abnormal vision, chromatopsia, rash, and headache; the most common treatment-related adverse events in the itraconazole group included bradycardia, diarrhea, and headache. Liver function test values were slightly higher in patients receiving voriconazole than in those receiving itraconazole; 2 patients in the voriconazole group were withdrawn from treatment because of increased liver function test values. In the intent-to-treat populations, the satisfactory response rate (i.e., complete or partial global response) was 88.6% among the voriconazole group and 94.4% among the itraconazole group. The response rate among treatment-evaluable patients was 100% for both treatment groups; no relapses were observed after 8 weeks of follow-up. This is, to our knowledge, the first study to demonstrate that voriconazole is as well tolerated and effective

Background Statin treatment in association with physical exercise can substantially reduce mortality in dyslipidaemic individuals. However, the available data to compare the efficacy and safety of statins and exercise combination therapy with statin monotherapy are limited. Design Systematic review and meta-analysis. Methods We systematically searched PubMed, Embase and the Cochrane Library from database inception until December 2016. We included randomised and non-randomised studies that compared the efficacy and safety of statins and exercise combination therapy with statin monotherapy in patients with dyslipidaemia. Standardised mean differences were calculated and pooled by means of fixed effects models. The risk of bias and heterogeneity among trials was also assessed. Seven articles were assessed in terms of the efficacy of therapy and 13 from the viewpoint of therapeutic safety. Results In terms of efficacy, statins and exercise combination decreased the incidence of diabetes mellitus, improved insulin sensitivity and inflammation, but caused no change in lipid profile compared to statins alone. In terms of safety, statins and exercise combination increased peak oxygen uptake (standardised mean difference 1.01, 95% confidence interval 0.46 to 1.57) compared to statins alone. In contrast to statin-induced myopathy, chronic exercise training prior to statin treatment could counteract statin-induced adverse effects in skeletal muscle. Conclusion Statins and exercise combination therapy is more effective than statin monotherapy in terms of insulin sensitivity, inflammation and exercise capacity. The small number of studies warrants the need for more randomised controlled trials evaluating the efficacy and safety of combination therapy.

To report our long-term experience of sacral neuromodulation (SNM) for various lower urinary tract dysfunctions but with a focus on efficacy, safety, re-interventions and degree of success. This is a single tertiary referral centre study that included 217 patients (86% female) who received an implantable pulse generator (IPG) (Interstim™, Medtronic, Minneapolis, USA) between 1996 and 2010. Success was considered if the initial ≥50% improvement in any of primary voiding diary variables persisted compared with baseline, but was further stratified. The mean duration of follow-up was 46.88 months. Success and cure rates were ≈70% and 20% for urgency incontinence, 68% and 33% for urgency frequency syndrome and 73% and 58% for idiopathic retention. In those patients with an unsuccessful therapy outcome, the mean time to failure was 24.6 months after implantation. There were 88 (41%) patients who had at least one device or treatment related surgical re-intervention. The re-intervention rate was 1.7 per patient with most of them (47%) occurring ≤2 years of follow-up. SNM appears effective in the long-term with a success rate after definitive IPG implant of ≈70% and complete cure rates ranging between 20% and 58% depending on indication. Patients with idiopathic retention appear to do best. The re-intervention rate is high with most occurring ≤2 years of implantation. It is likely that with the newer techniques used, efficacy and re-intervention rates will improve. © 2013 The Authors. BJU International © 2013 BJU International.

As management of multiple sclerosis (MS) requires life-long treatment with disease-modifying agents, any risks associated with long-term use should be considered when evaluating therapeutic options. Immune cells of the innate and adaptive immune systems play various roles in the pathogenesis of MS. MS therapies affect the immune system, each with a unique mode of action, and consequently possess different long-term safety profiles. Rare, but serious safety concerns, including an increased risk of infection and cancer, have been associated with immunosuppressant use. The risks associated with newer immunosuppressive agents, which target specific elements of MS disease pathophysiology, are not yet fully established as the duration of clinical trials is relatively short and post-marketing experience is limited. Non-immunosuppressants used to treat MS have well-defined safety profiles established over a large number of patient-years demonstrating them to be well-tolerated long-term treatment options. When considering the long-term use of disease-modifying agents for treating MS, classification as immunosuppressants or non-immunosuppressants can be useful when evaluating potential risks associated with chronic use. A successful therapeutic strategy for any serious, chronic disease such as MS should weigh effectiveness versus long-term safety of available treatments.

Tissue engineering appears to be an attractive alternative to the traditional approach in the treatment of fracture non-unions. Mesenchymal stromal cells (MSCs) are considered an appealing cell source for clinical intervention. However, ex vivo cell expansion and differentiation towards the osteogenic lineage, together with the design of a suitable scaffold have yet to be optimized. Major concerns exist about the safety of MSC-based therapies, including possible abnormal overgrowth and potential cancer evolution. We examined the long-term efficacy and safety of ex vivo expanded bone marrow MSCs, embedded in autologous fibrin clots, for the healing of atrophic pseudarthrosis of the upper limb. Our research work relied on three main issues: use of an entirely autologous context (cells, serum for ex vivo cell culture, scaffold components), reduced ex vivo cell expansion, and short-term MSC osteoinduction before implantation. Bone marrow MSCs isolated from 8 patients were expanded ex vivo until passage 1 and short-term osteo-differentiated in autologous-based culture conditions. Tissue-engineered constructs designed to embed MSCs in autologous fibrin clots were locally implanted with bone grafts, calibrating their number on the extension of bone damage. Radiographic healing was evaluated with short- and long-term follow-ups (range averages: 6.7 and 76.0 months, respectively). All patients recovered limb function, with no evidence of tissue overgrowth or tumor formation. Our study indicates that highly autologous treatment can be effective and safe in the long-term healing of bone non-unions. This tissue engineering approach resulted in successful clinical and functional outcomes for all patients.

There is growing evidence for anti-inflammatory activities of macrolides in chronic respiratory diseases, such as diffuse panbronchiolitis, cystic fibrosis, or chronic bronchitis. The long-term effect of macrolides in idiopathic pulmonary fibrosis (IPF) is unknown. This study was aimed to investigate the effect of macrolide therapy on the frequency of acute exacerbation (AE) and the mortality in IPF. A total 52 IPF patients who were treated by combination of conventional agents with or without macrolides were retrospectively reviewed. The primary endpoint was the incidence of AE in IPF patients. We also observed survival rate after the treatment with or without macrolides. AE was observed in 4 of 29 cases (13.8%) treated with macrolides and 8 of 23 cases (34.8%) treated without macrolides, respectively during 36 months. AE free survival rate of macrolide group was significantly better than that of non-macrolide group (logrank p=0.027). Survival rate of IPF patients with macrolide therapy was significantly better than that of patients without macrolide therapy (p=0.047). Our results indicate the potential beneficial efficacy of macrolide therapy combined with oral corticosteroids, immunosuppressive or anti-fibrotic agents in IPF.

To assess efficacy, stability and safety of posterior chamber phakic intraocular lens implantation with STAAR Visian ICL for correction of high ametropia, with a mean follow-up of 5 years (3.5-10 years). Ninety eyes of 53 highly ametropic patients (45 myopia, ten hyperopia and 35 with mixed astigmatism) were included in a retrospective single-surgeon study, using primarily the V4 ICL model (87 eyes). We studied pre- and postoperative refractive efficacy, endothelial cell density, crystalline lens opacification and intraocular clearances within the various compartments of the eye. Mean uncorrected visual acuity was 0.77 at the 12th postoperative month; 17 of 90 eyes required adjunctive photoablation for residual astigmatism. Forty-eight percent of eyes gained at least one line of best corrected visual acuity. After implantation, the decrease in endothelial cell density remained stable at 0.69%/year, and 91% of eyes showed no opacification of the crystalline lens. Mean endothelium-ICL and ICL-crystalline lens distances were 2.41 mm and 0.52 mm respectively. Overall patient satisfaction achieved was 96% at 36 months postoperatively. These results demonstrate efficacy, stability and safety of the ICL V4 phakic IOL for the correction of high ametropia. Long-term follow-up did not show a significant increase in cataract formation in implanted eyes. Copyright © 2012. Published by Elsevier Masson SAS.

Background: Staphylococcus aureus biofilms contribute negatively to a number of chronic conditions, including chronic rhinosinusitis (CRS). With the inherent tolerance of biofilm-bound bacteria to antibiotics and the global problem of bacterial antibiotic resistance, the need to develop novel therapeutics is paramount. Phage therapy has previously shown promise in treating sinonasal S. aureus biofilms. Methods: This study investigates the long term (20 days) safety of topical sinonasal flushes with bacteriophage suspensions. The bacteriophage cocktail NOV012 against S. aureus selected for this work contains two highly characterized and different phages, P68 and K710. Host range was assessed against S. aureus strains isolated from CRS patients using agar spot tests. NOV012 was applied topically to the frontal sinus region of sheep, twice daily for 20 days. General sheep wellbeing, mucosal structural changes and inflammatory load were assessed to determine safety of NOV012 application. Results: NOV012 could lyse 52/61 (85%) of a panel of locally derived CRS clinical isolates. Application of NOV012 to the frontal sinuses of sheep for 20 days was found to be safe, with no observed inflammatory infiltration or tissue damage within the sinus mucosa. Conclusion: NOV012 cocktail appears safe to apply for extended periods to sheep sinuses and it could infect and lyse a wide range of S. aureus CRS clinical isolates. This indicates that phage therapy has strong potential as a treatment for chronic bacterial rhinosinusitis. PMID:28286740

Anxiety symptoms are among the most common reasons for consumers to use Complementary and Alternative Medicine (CAM) therapy. Although many botanicals have been proposed as putative remedies for anxiety symptoms, there has been a paucity of controlled trials of these remedies. A preliminary study of the anxiolytic effect of Chamomile ( Matricaria recutita ) in humans suggests that chamomile may have anxiolytic and antidepressant activity. We now seek to conduct a 5-year randomized, double-blind, placebo-substitution study to examine the short and long-term safety and efficacy of chamomile extract in Generalized Anxiety Disorder (GAD). 180 subjects with moderate to severe GAD will receive initial open-label pharmaceutical-grade chamomile extract 500-1,500 mg daily for 8 weeks. Responders to treatment who remain well for an additional 4 weeks of consolidation therapy, will be randomized to double-blind continuation therapy with either chamomile extract 500-1,500 mg daily or placebo for an additional 26 weeks. The primary outcome will be the time to relapse during study continuation therapy in each treatment condition. Secondary outcomes will include the proportion of subjects in each treatment condition who relapse, as well as the proportion of subjects with treatment-emergent adverse events. Quality of life ratings will also be compared between treatment conditions during short and long-term therapy. Many individuals with mental disorders decline conventional therapy and seek CAM therapies for their symptoms. Thus, the identification of effective CAM therapy is of relevance to reducing the burden of mental illness. This study builds upon our prior findings of significant superiority of chamomile versus placebo in reducing GAD symptoms. We now extend these preliminary findings by conducting a randomized long-term safety and efficacy study of chamomile in GAD.

Methods/Design 180 subjects with moderate to severe GAD will receive initial open-label pharmaceutical-grade chamomile extract 500–1,500 mg daily for 8 weeks. Responders to treatment who remain well for an additional 4 weeks of consolidation therapy, will be randomized to double-blind continuation therapy with either chamomile extract 500–1,500 mg daily or placebo for an additional 26 weeks. The primary outcome will be the time to relapse during study continuation therapy in each treatment condition. Secondary outcomes will include the proportion of subjects in each treatment condition who relapse, as well as the proportion of subjects with treatment-emergent adverse events. Quality of life ratings will also be compared between treatment conditions during short and long-term therapy. Discussion Many individuals with mental disorders decline conventional therapy and seek CAM therapies for their symptoms. Thus, the identification of effective CAM therapy is of relevance to reducing the burden of mental illness. This study builds upon our prior findings of significant superiority of chamomile versus placebo in reducing GAD symptoms. We now extend these preliminary findings by conducting a randomized long-term safety and efficacy study of chamomile in GAD. PMID:29057164

This study evaluated the long-term efficacy of denture cleansers against Candida spp. biofilm recolonization on liner surface. Specimens were fabricated of a poly(methyl methacrylate)-based denture liner and had their surface roughness evaluated at baseline and after cleansing treatments. C. albicans or C. glabrata biofilms were formed on liner surface for 48 h, and then the specimens were randomly assigned to one of cleaning treatments: two alkaline peroxides (soaking for 3 or 15 min), 0.5% sodium hypochlorite (10 min) or distilled water (control; 15 min). After the treatments, the specimens were sonicated to disrupt the biofilm, and residual cells were counted (cell/mL). Long-term effectiveness of the cleaning processes was determined by submitting a set of cleaned specimens to biofilm growth conditions for 48 h followed by estimation of cell counts. The topography of specimens after cleaning treatments was analyzed by SEM. Data were analyzed by ANOVA and Tukey's test (α; = 0.05). Results of cell count estimation showed significant differences in cleanliness among the treatments (p < 0.001), and it could be observed by SEM. However, no significant difference (p > 0.05) was observed among the Candida species regarding the recolonization condition. Alkaline denture cleansers showed similar cleaning performance and both differed from the control (p < 0.001). Sodium hypochlorite was the only treatment that removed biofilm efficiently, since no viable cells were found after its use. In conclusion, alkaline peroxide denture cleansers were not effective in removing Candida spp. biofilm from denture liner surfaces and preventing biofilm recolonization.

Previous analysis of COMBI-d (NCT01584648) demonstrated improved progression-free survival (PFS) and overall survival (OS) with combination dabrafenib and trametinib versus dabrafenib monotherapy in BRAF V600E/K-mutant metastatic melanoma. This study was continued to assess 3-year landmark efficacy and safety after ≥36-month follow-up for all living patients. This double-blind, phase 3 study enrolled previously untreated patients with BRAF V600E/K-mutant unresectable stage IIIC or stage IV melanoma. Patients were randomized to receive dabrafenib (150 mg twice daily) plus trametinib (2 mg once daily) or dabrafenib plus placebo. The primary endpoint was PFS; secondary endpoints were OS, overall response, duration of response, safety, and pharmacokinetics. Between 4 May and 30 November 2012, a total of 423 of 947 screened patients were randomly assigned to receive dabrafenib plus trametinib (n = 211) or dabrafenib monotherapy (n = 212). At data cut-off (15 February 2016), outcomes remained superior with the combination: 3-year PFS was 22% with dabrafenib plus trametinib versus 12% with monotherapy, and 3-year OS was 44% versus 32%, respectively. Twenty-five patients receiving monotherapy crossed over to combination therapy, with continued follow-up under the monotherapy arm (per intent-to-treat principle). Of combination-arm patients alive at 3 years, 58% remained on dabrafenib plus trametinib. Three-year OS with the combination reached 62% in the most favourable subgroup (normal lactate dehydrogenase and <3 organ sites with metastasis) versus only 25% in the unfavourable subgroup (elevated lactate dehydrogenase). The dabrafenib plus trametinib safety profile was consistent with previous clinical trial observations, and no new safety signals were detected with long-term use. These data demonstrate that durable (≥3 years) survival is achievable with dabrafenib plus trametinib in patients with BRAF V600-mutant metastatic melanoma and support long-term

The Long-Term Oxygen Treatment Trial demonstrated that long-term supplemental oxygen did not reduce time to hospital admission or death for patients who have stable chronic obstructive pulmonary disease and resting and/or exercise-induced moderate oxyhemoglobin desaturation, nor did it provide benefit for any other outcome measured in the trial. Nine months after initiation of patient screening, after randomization of 34 patients to treatment, a trial design amendment broadened the eligible population, expanded the primary outcome, and reduced the goal sample size. Within a few years, the protocol underwent minor modifications, and a second trial design amendment lowered the required sample size because of lower than expected treatment group crossover rates. After 5.5 years of recruitment, the trial met its amended sample size goal, and 1 year later, it achieved its follow-up goal. The process of publishing the trial results brought renewed scrutiny of the study design and the amendments. This article expands on the previously published design and methods information, provides the rationale for the amendments, and gives insight into the investigators' decisions about trial conduct. The story of the Long-Term Oxygen Treatment Trial may assist investigators in future trials, especially those that seek to assess the efficacy and safety of long-term oxygen therapy.

Long-term safety of PEG 4000 in children with chronic functional constipation: A biochemical perspective

PubMed Central

2010-01-01

Purpose To evaluate the long-term safety of polyethylene glycol (PEG) 4000 in children with constipation, particularly the biochemical aspects of safety. Methods Medical records were evaluated, and 100 children, who had been taking PEG 4000 for more than 6 months, and who had been under clinical and biochemical monitoring, were enrolled. Ages; 6.11±3.12 years, Duration of therapy; 16.93±7.02 months, dose of PEG 4000; 0.72±0.21 g/kg/d. Results None of the children complained of clinical adverse effect. The first biochemical test was performed at 8.05 months after beginning of PEG 4000. Serum phosphate (SP) value was high in 10 children, and leucopenia was noted in one child. The second test was performed in 44 children at 7.57 months after the first test. The SP value was high in four children, including the three children whose initial SP value was high and one new child. Six out of 10 children with high initial SP value became normal and one was lost. Hypernatremia was noted in one child. The third test was done in 15 children at 7.5 months after the second test. The SP value of the new child from the second test was high, but became normal after finishing treatment. Two out of 3 children with high SP value at the second test became normal and one was lost. The fourth test was done in 2 children few months after the third test. All of the results were normal. There were no relation between duration of therapy and hyperphosphatemia, or between dose of PEG 4000 and hyperphosphatemia. Conclusions PEG 4000 is safe for long-term therapy in children with constipation with respect to biochemical parameters. PMID:21189949

Theophylline can still have a role in the management of stable chronic obstructive pulmonary disease (COPD), but its use remains controversial, mainly due to its narrow therapeutic window. Doxofylline, another xanthine, is an effective bronchodilator and displays a better safety profile than theophylline. Therefore, we performed a quantitative synthesis to compare the efficacy and safety profile of different xanthines in COPD.The primary end-point of this meta-analysis was the impact of xanthines on lung function. In addition, we assessed the risk of adverse events by normalising data on safety as a function of person-weeks. Data obtained from 998 COPD patients were selected from 14 studies and meta-analysed using a network approach.The combined surface under the cumulative ranking curve (SUCRA) analysis of efficacy (change from baseline in forced expiratory volume in 1 s) and safety (risk of adverse events) showed that doxofylline was superior to aminophylline (comparable efficacy and significantly better safety), bamiphylline (significantly better efficacy and comparable safety), and theophylline (comparable efficacy and significantly better safety).Considering the overall efficacy/safety profile of the investigated agents, the results of this quantitative synthesis suggest that doxofylline seems to be the best xanthine for the treatment of COPD.

Long-term Use of Opioids for Complex Chronic Pain

PubMed Central

Von Korff, Michael R.

2014-01-01

Increased opioid prescribing for back pain and other chronic musculoskeletal pain conditions has been accompanied by dramatic increases in prescription opioid addiction and fatal overdose. Opioid-related risks appear to increase with dose. While short-term randomized trials of opioids for chronic pain have found modest analgesic benefits (a one-third reduction in pain intensity on average), the long-term safety and effectiveness of opioids for chronic musculoskeletal pain is unknown. Given the lack of large, long-term randomized trials, recent epidemiologic data suggests the need for caution when considering long-term use of opioids to manage chronic musculoskeletal pain, particularly at higher dosage levels. Principles for achieving more selective and cautious use of opioids for chronic musculoskeletal pain are proposed. PMID:24315147

The tyrosine kinase inhibitor Imatinib Mesylate has dramatically improved the clinical outcome of chronic myeloid leukemia (CML) patients in the chronic phase of the disease, generating unprecedented rates of complete hematologic and cytogenetic responses and sustained reductions in BCR-ABL transcripts. Here, we present an overview on the efficacy and safety of Imatinib and describe the most important clinical studies employing this drug for the frontline treatment of chronic phase CML. We also discuss recent reports describing the long-term outcome of patients receiving Imatinib for their disease. The imminent availability of generic forms of Imatinib coupled with the approval of expensive second-generation tyrosine kinase inhibitors underlines an unmet need for early molecular parameters that may distinguish CML patients likely to benefit from the drug from those that should receive alternative forms of treatment.

An observational study was conducted to explore postmarketing safety and efficacy of Deferasirox (DFX) in comparison with conventional Desferrioxamine (DFO) in chelation-naïve children with transfusional iron overload. Transfusion-dependent children (aged ≤ 5 yr) who had serum ferritin above 1000 μg/L and had been prescribed either first-line DFX or DFO for at least 12 months to maintain serum ferritin between 500 and 1000 μg/L were included. Initial DFX dose was 20 mg/kg/d for 7 d a week, and DFO dose was 25-35 mg/kg/d subcutaneously, given for 5 d a week. Dose adjustments were based on serum ferritin changes and safety markers. The primary efficacy endpoint was change in serum ferritin from baseline. The effect of transfusional iron loading rate (ILR) and different doses of chelators on serum ferritin was also assessed. A total of 111 patients were observed for a median of 2.29 yr on DFX (n = 71) and 2.75 yr on DFO (n = 40). Absolute change in serum ferritin from baseline to the last available observation was not significant with DFX (91 μg/L, P = 0.5) but significantly higher with DFO (385 μg/L, P < 0.005). ILR and DFX doses had a major impact on serum ferritin changes in DFX cohort. The height- and weight-standard deviation scores did not differ significantly in both cohorts during the study. Fluctuations in liver enzymes and non-progressive increase in serum creatinine were the most common adverse events (DFX; 9.8%, 18.0% and DFO; 5.0%, 7.5%, respectively). DFX is well tolerable and at least as effective as DFO to maintain safe serum ferritin levels and normal growth progression in chelation-naïve children. © 2012 John Wiley & Sons A/S.

Abstract Transthyretin hereditary amyloid polyneuropathy, also traditionally known as transthyretin familial amyloid polyneuropathy (ATTR-FAP), is a rare, relentless, fatal hereditary disorder. Tafamidis, an oral, non-NSAID, highly specific transthyretin stabilizer, demonstrated safety and efficacy in slowing neuropathy progression in early-stage ATTRV30M-FAP in a 1.5-year, randomized, double-blind, placebo-controlled trial, and 1-year open-label extension study, with a second long-term open-label extension study ongoing. Subgroup analysis of the effectiveness of tafamidis in the pivotal study and its open-label extensions revealed a relatively cohesive cohort of patients with mild neuropathy (i.e. Neuropathy Impairment Score for Lower Limbs [NIS-LL] ≤ 10) at the start of active treatment. Early treatment with tafamidis for up to 5.5 years (≥1 dose of tafamidis meglumine 20 mg once daily during the original trial or after switching from placebo in its extension) resulted in sustained delay in neurologic progression and long-term preservation of nutritional status in this cohort. Mean (95% CI) changes from baseline in NIS-LL and mBMI were 5.3 (1.6, 9.1) points and −7.8 (−44.3, 28.8) kg/m2 × g/L at 5.5 years, respectively. No new safety issues or side effects were identified. These data represent the longest prospective evaluation of tafamidis to date, confirm a favorable safety profile, and underscore the long-term benefits of early intervention with tafamidis. Trial Registration: ClincalTrials.gov Identifier: NCT00409175, NCT00791492, and NCT00925002. PMID:27494299

Ivacaftor, a cystic fibrosis transmembrane conductance regulator (CFTR) potentiator, is approved for the treatment of patients with cystic fibrosis aged 6 years or older with Gly551Asp-CFTR. We assessed the safety and efficacy of ivacaftor during 96 weeks of PERSIST in patients with cystic fibrosis who completed a previous 48-week, placebo-controlled trial of the drug (STRIVE or ENVISION). In this phase 3, open-label extension study, patients received ivacaftor 150 mg every 12 h in addition to their prescribed cystic fibrosis therapies. Patients who received placebo in their previous study initiated ivacaftor in this extension study. Patients were eligible if they had a Gly551Asp-CFTR mutation on at least one allele. The primary objective was to assess the long-term safety profile of ivacaftor as assessed by adverse events, clinical laboratory assessments, electrocardiograms, vital signs, and physical examination; secondary measures included change in forced expiratory volume in one second (FEV1), weight, and pulmonary exacerbations. This study is registered with ClinicalTrials.gov, number NCT01117012 and EudraCT, number 2009-012997-11. Between July 8, 2010, and April 8, 2013, 144 adolescents/adults (≥12 years) from STRIVE and 48 children (6-11 years) from ENVISION were enrolled. Across both trials, 38 (20%) patients had a serious adverse event during the first 48 weeks and 44 (23%) during the subsequent 48 weeks. Two adults (1%) and one child (<1%) discontinued because of adverse events. The most common adverse events were pulmonary exacerbation, cough, and upper respiratory tract infection. Patients previously treated with ivacaftor had sustained improvements in FEV1, weight, and rate of pulmonary exacerbations for up to 144 weeks of treatment. Among adolescents/adults and children who previously received ivacaftor, absolute change in FEV1 at week 96 (144 weeks ivacaftor) was 9·4 and 10·3 % points and absolute increase in weight was 4·1 kg and 14·8 kg

Surgical and conservative treatment of patients with congenital scoliosis: α search for long-term results

PubMed Central

2011-01-01

Background In view of the limited data available on the conservative treatment of patients with congenital scoliosis (CS), early surgery is suggested in mild cases with formation failures. Patients with segmentation failures will not benefit from conservative treatment. The purpose of this review is to identify the mid- or long-term results of spinal fusion surgery in patients with congenital scoliosis. Methods Retrospective and prospective studies were included, reporting on the outcome of surgery in patients with congenital scoliosis. Studies concerning a small numbers of cases treated conservatively were included too. We analyzed mid-term (5 to 7 years) and long-term results (7 years or more), both as regards the maintenance of the correction of scoliosis and the safety of instrumentation, the early and late complications of surgery and their effect on quality of life. Results A small number of studies of surgically treated patients were found, contained follow-up periods of 4-6 years that in the most cases, skeletal maturity was not yet reached, and few with follow-up of 36-44 years. The results of bracing in children with congenital scoliosis, mainly in cases with failure of formation, were also studied. Discussion Spinal surgery in patients with congenital scoliosis is regarded in short as a safe procedure and should be performed. On the other hand, early and late complications are also described, concerning not only intraoperative and immediate postoperative problems, but also the safety and efficacy of the spinal instrumentation and the possibility of developing neurological disorders and the long-term effect these may have on both lung function and the quality of life of children. Conclusions Few cases indicate the long-term results of surgical techniques, in the natural progression of scoliosis. Similarly, few cases have been reported on the influence of conservative treatment. In conclusion, patients with segmentation failures should be treated

The effectiveness of a long-term professional development program on teachers' self-efficacy, attitudes, skills, and knowledge using a thematic learning approach

Tinnin, Richard Kinna

The purpose of this research study was to determine the effectiveness of a long-term professional development program on self-efficacy beliefs, science attitudes, skills, and knowledge of elementary teachers. The target school was located in the Lower Rio Grande Valley of Texas. Major elements of the study included the use of thematic science strands, use of the 5E constructivist-oriented instructional model, a focus on the interdisciplinary nature of the science process skills, and guided, inquiry-based learning experiences. These elements mirror the principles identified as being essential components of effective professional development for mathematics, and science education (Fullan, 1985; Sparks & Loucks-Horsley, 1990; Loucks-Horsley, 1997). The research team was actively involved with the participants for a total of 30 days at their school over the 24 months of the study. During each training, the research team modeled the 5E constructivist-oriented instructional strategy, and the interdisciplinary nature of the science process skills, set up a wide variety of activity centers, and provided the teachers with opportunities to improve their attitudes, skills, and knowledge of the science content, and teaching strategies. The 15 participants completed pre-, post-, and post-post-Leadership Team Surreys. Quantitative data analyses of gain scores measuring level of confidence to teach Marine and Earth Science, content knowledge, and teaching strategies were significant, p < .001. The participants' efficacy-beliefs and outcome expectancy were assessed with a pre- and posttest Science Teacher Self-Efficacy Beliefs Instrument that measures both elements. Self-efficacy beliefs were significant at p < .001. Outcome expectancies were not significant, p > .05. Qualitative analysis of reflective journal comments, classroom observations, and the participants understanding, and use of science process skills across the curriculum supported the quantitative data results.

The Pickwick project was a prospective, randomized and controlled study, which addressed the issue of obesity hypoventilation syndrome (OHS), a growing problem in developed countries. OHS patients were divided according to apnea-hypopnea index (AHI) ≥30 and <30 determined by polysomnography. The group with AHI≥30 was randomized to intervention with lifestyle changes, noninvasive ventilation (NIV) or continuous positive airway pressure (CPAP); the group with AHI<30 received NIV or lifestyle changes. The aim of the study was to evaluate the efficacy of NIV treatment, CPAP and lifestyle changes (control) in the medium and long-term management of patients with OHS. The primary variables were PaCO2 and days of hospitalization, and operating variables were the percentage of dropouts for medical reasons and mortality. Secondary medium-term objectives were: (i)to evaluate clinical-functional effectiveness on quality of life, echocardiographic and polysomnographic variables; (ii)to investigate the importance of apneic events and leptin in the pathogenesis of daytime alveolar hypoventilation and change according to the different treatments; (ii)to investigate whether metabolic, biochemical and vascular endothelial dysfunction disorders depend on the presence of apneas and hypopneasm and (iv)changes in inflammatory markers and endothelial damage according to treatment. Secondary long-term objectives were to evaluate: (i)clinical and functional effectiveness and quality of life with NIV and CPAP; (ii)changes in leptin, inflammatory markers and endothelial damage according to treatment; (iii)changes in pulmonary hypertension and other echocardiographic variables, as well as blood pressure and incidence of cardiovascular events, and (iv)dropout rate and mortality.

Bronchial thermoplasty (BT) is a novel treatment for severe asthma. Its mode of action and ideal target patient group remain poorly defined, though clinical trials provided some evidence on efficacy and safety. This study presents procedural and short-term safety evidence from routine UK clinical practice. Patient characteristics and safety outcomes (procedural complications, 30-day readmission and accident and emergency (A&E) attendance, length of stay) were assessed using two independent data sources, the British Thoracic Society UK Difficult Asthma Registry (DAR) and Hospital Episodes Statistics (HES) database. A matched cohort (with records in both) was used to estimate safety outcome event rates and compare them with clinical trials. Between June 2011 and January 2015, 215 procedure records (83 patients; 68 treated in England) were available from DAR and 203 (85 patients) from HES. 152 procedures matched (59 patients; 6 centres), and of these, 11.2% reported a procedural complication, 11.8% resulted in emergency respiratory readmission, 0.7% in respiratory A&E attendance within 30 days (20.4% had at least one event) and 46.1% involved a post-procedure stay. Compared with published clinical trials which found lower hospitalisation rates, BT patients in routine clinical practice were, on average, older, had worse baseline lung function and asthma quality of life. A higher proportion of patients experienced adverse events compared with clinical trials. The greater severity of disease amongst patients treated in clinical practice may explain the observed rate of post-procedural stay and readmission. Study of long-term safety and efficacy requires continuing data collection.

Safety and efficacy of epicutaneous immunotherapy for food allergy.

PubMed

Wang, Julie; Sampson, Hugh A

2018-06-01

Food allergy is increasingly common in children, affecting about 4%-8%. The mainstays of management remain allergen avoidance and emergency preparedness to treat allergic reactions with emergency medications. Unfortunately, these approaches are unsatisfactory for many patients and their families as the restrictions, constant vigilance, and unpredictable severity of allergic reactions negatively impact quality of life. In recent decades, there has been significant interest in developing treatments for food allergy that lead to desensitization to increase thresholds for triggering allergic reactions and decrease the risk of reacting to allergen-contaminated food products. Epicutaneous immunotherapy (EPIT) is a novel therapy that is currently under investigation, delivering allergen via repeated applications to the skin and targeting antigen-presenting cells in the superficial skin layers. Murine models have demonstrated that allergen uptake is an active process by skin dendritic cells with subsequent migration to draining lymph nodes. Allergen exposure to the non-vascularized epidermis limits systemic absorption, contributing to the high-safety profile. Results from murine experiments showed that EPIT has comparable efficacy as subcutaneous immunotherapy in terms of challenge outcomes, airway hyper-responsiveness, and immunologic parameters. Several clinical trials of EPIT have recently been completed or are ongoing. Results support the high safety and tolerability of this approach. Efficacy data suggest that the change in threshold eliciting dose following 1 year of therapy is less than that seen compared to high-dose (2-4 g peanut protein) oral immunotherapy, but more prolonged treatment with EPIT appears to lead to increasing desensitization. Additional data from larger-scale studies should provide a more robust assessment of safety and efficacy of EPIT. © 2018 EAACI and John Wiley and Sons A/S. Published by John Wiley and Sons Ltd.

Introduction The 308 nm excimer laser is a widely used device throughout the field of dermatology for many diseases including psoriasis. Although the laser has demonstrated clinical efficacy, there is a lack of literature outlining the safety, efficacy, and patient acceptability of the excimer laser. Methods A literature search on PubMed was used with combinations of the terms “excimer”, “excimer laser”, “308 nm”, “psoriasis”, “protocol”, “safety”, “efficacy”, acceptability”, “side effects”, and “dose”. The search results were included if they contained information pertaining to excimer laser and psoriasis treatment and description of the safety, efficacy, and patient acceptability of the treatment. Results The 308 nm excimer laser is generally safe and well tolerated with minimal side effects including erythema, blistering, and pigmentary changes. It has a range of efficacies depending on the protocol used with several different treatment protocols, including the induration protocol, the minimal erythema dose protocol, and the newer minimal blistering dose protocol. Conclusion Although the excimer laser is not a first-line treatment, it remains an excellent treatment option for psoriasis patients and has been demonstrated to be an effective treatment with little to no side effects.

A case is presented in which the staff of a long-term care facility discovers that the husband of a resident with dementia is engaged in sexual activity with her. The case illustrates a dilemma for long-term care facilities that create a home-like environment with a goal of maximizing residents' autonomy while ensuring their safety. An approach to assessing capacity to consent to intimate sexual activity is described, followed by guidelines that nursing homes can implement to support residents who wish to engage in sexual activity. Recommendations are also offered for supporting long-term care staff and family members of residents who are interested in intimate sexual activity. © 2017 American Medical Association.

Long-term use of short- and long-acting nitrates in stable angina pectoris.

PubMed

Kosmicki, Marek Antoni

2009-05-01

Long-acting nitrates are effective antianginal drugs during initial treatment. However, their therapeutic value is compromised by the rapid development of tolerance during sustained therapy, which means that their clinical efficacy is decreased during long-term use. Sublingual nitroglycerin (NTG), a short-acting nitrate, is suitable for the immediate relief of angina. In patients with stable angina treated with oral long-acting nitrates, NTG maintains its full anti-ischemic effect both after initial oral ingestion and after intermittent long-term oral administration. However, NTG attenuates this effect during continuous treatment, when tolerance to oral nitrates occurs, and this is called cross-tolerance. In stable angina long-acting nitrates are considered third-line therapy because a nitrate-free interval is required to avoid the development of tolerance. Nitrates vary in their potential to induce the development of tolerance. During long-lasting nitrate therapy, except pentaerythritol tetranitrate (PETN), one can observe the development of reactive oxygen species (ROS) inside the muscular cell of a vessel wall, and these bind with nitric oxide (NO). This leads to decreased NO activity, thus, nitrate tolerance. PETN has no tendency to form ROS, and therefore during long-term PETN therapy, there is probably no tolerance or cross-tolerance, as during treatment with other nitrates.

The Aegean Sea is characterized by an extremely high marine safety risk, mainly due to the significant increase of the traffic of tankers from and to the Black Sea that pass through narrow straits formed by the 1600 Greek islands. Reducing the risk of a ship accident is therefore vital to all socio-economic and environmental sectors. This paper presents an online long-term marine traffic monitoring work-flow that focuses on extracting aggregated vessel risks using spatiotemporal analysis of multilayer information: vessel trajectories, vessel data, meteorological data, bathymetric / hydrographic data as well as information regarding environmentally important areas (e.g. protected high-risk areas, etc.). A web interface that enables user-friendly spatiotemporal queries is implemented at the frontend, while a series of data mining functionalities extracts aggregated statistics regarding: (a) marine risks and accident probabilities for particular areas (b) trajectories clustering information (c) general marine statistics (cargo types, etc.) and (d) correlation between spatial environmental importance and marine traffic risk. Towards this end, a set of data clustering and probabilistic graphical modelling techniques has been adopted.

Obesity is a major health problem worldwide. Although diet and physical activity are crucial in the management of obesity, the long-term success rate is low. Therefore antiobesity drugs are of great interest, especially when lifestyle modification has failed. As obesity is not an immediate life-threatening disease, these drugs are required to be safe. Antiobesity drugs that have been developed so far have limited efficacies and considerable adverse effects affecting tolerability and safety. Therefore, most antiobesity drugs have been withdrawn. Fenfluramine and dexfenfluramine were withdrawn because of the potential damage to heart valves. Sibutramine was associated with an increase in major adverse cardiovascular events in the Sibutramine Cardiovascular Outcomes (SCOUT) trial and it was withdrawn from the market in 2010. Rimonabant was withdrawn because of significant psychiatric adverse effects. Orlistat was approved in Europe and the United States for long-term treatment of obesity, but many patients cannot tolerate its gastrointestinal side effects. Phentermine and diethylpropion can only be used for less than 12 weeks because the long-term safety of these drugs is unknown. Ephedrine and caffeine are natural substances but the effects on weight reduction are modest. As a result there is a huge unmet need for effective and safe antiobesity drugs. Recently lorcaserin and topiramate plus phentermine have been approved for the treatment of obesity but long-term safety data are lacking. PMID:25114779

Aims We aimed to evaluate the safety and long-term efficacy of the magnetic navigation system (MNS) in a large number of patients. The MNS has the potential for improving safety and efficacy based on atraumatic catheter design and superior navigation capabilities. Methods and results In this study, 610 consecutive patients underwent ablation. Patients were divided into two age- and sex-matched groups. Ablations were performed either using MNS (group MNS, 292) or conventional manual ablation [group manual navigation (MAN), 318]. The following parameters were analysed: acute success rate, fluoroscopy time, procedure time, complications [major: pericardial tamponade, permanent atrioventricular (AV) block, major bleeding, and death; minor: minor bleeding and temporary AV block]. Recurrence rate was assessed during follow-up (15 ± 9.5 months). Subgroup analysis was performed for the following groups: atrial fibrillation, isthmus dependent and atypical atrial flutter, atrial tachycardia, AV nodal re-entrant tachycardia, circus movement tachycardia, and ventricular tachycardia (VT). Magnetic navigation system was associated with less major complications (0.34 vs. 3.2%, P = 0.01). The total numbers of complications were lower in group MNS (4.5 vs. 10%, P = 0.005). Magnetic navigation system was equally effective as MAN in acute success rate for overall groups (92 vs. 94%, P = ns). Magnetic navigation system was more successful for VTs (93 vs. 72%, P < 0.05). Less fluoroscopy was used in group MNS (30 ± 20 vs. 35 ± 25 min, P < 0.01). There were no differences in procedure times and recurrence rates for the overall groups (168 ± 67 vs. 159 ± 75 min, P = ns; 14 vs. 11%, P = ns; respectively). Conclusions Our data suggest that the use of MNS improves safety without compromising efficiency of ablations. Magnetic navigation system is more effective than manual ablation for VTs.

Recently, the use of biosimilar infliximab (IFX) in the treatment of inflammatory bowel diseases has become widespread in some European and non-European countries. Data on the efficacy, safety and immunogenicity from real-life cohorts are accumulating. The first reports showed similar outcomes in the induction and maintenance of remission, mucosal healing, safety and immunogenicity profile to the originator IFX. In the present review, we aimed to summarize the existing knowledge on the efficacy, safety and immunogenicity profile of biosimilar IFX reported from real-life cohorts. © 2017 S. Karger AG, Basel.

Silodosin for the treatment of clinical benign prostatic hyperplasia: safety, efficacy, and patient acceptability.

α1-Adrenergic receptor antagonists are commonly used to treat male lower urinary tract symptoms and benign prostatic hyperplasia (BPH). We performed a literature search using PubMed, Medline via Ovid, Embase, and the Cochrane Library databases to identify studies on the treatment of BPH by silodosin. Silodosin is a novel α1-adrenergic receptor antagonist whose affinity for the α1A-adrenergic receptor is greater than that for the α1B-adrenergic receptor. Therefore, silodosin does not increase the incidence of blood pressure-related side effects, which may result from the inhibition of the α1B-adrenergic receptor. Patients receiving silodosin at a daily dose of 8 mg showed a significant improvement in the International Prostate Symptom Score and maximum urinary flow rate compared with those receiving a placebo. Silodosin also improved both storage and voiding symptoms, indicating that silodosin is effective, even during early phases of BPH treatment. Follow-up extension studies performed in the United States, Europe, and Asia demonstrated its long-term safety and efficacy. In the European study, silodosin significantly reduced nocturia compared to the placebo. Although retrograde or abnormal ejaculation was the most commonly reported symptom in these studies, only a few patients discontinued treatment. The incidence of adverse cardiovascular events was also very low. Evidence showing solid efficacy and cardiovascular safety profiles of silodosin will provide a good solution for the treatment of lower urinary tract symptoms associated with BPH in an increasingly aging society.

This is the first report of long-term (>10 years) safety, tolerability, and survival data on patients with non-small cell lung cancer (NSCLC) who received treatment with gefitinib, an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor. Patients with advanced NSCLC (N = 191) who entered the IRESSA Clinical Access Program (ICAP) (June 2011 to January 2013) and had previously obtained a clinical benefit from gefitinib therapy (including patients who had received gefitinib since 2001) were analyzed for adverse events (AEs). A subset of patients (n = 79) underwent retrospective chart review to capture demographic, safety, and survival data. Seventy-five of 191 patients (39%) remained on long-term gefitinib therapy as of September 2016. Overall, serious AEs (SAEs) were reported in 64 patients (34%), the majority of which were attributed to underlying disease or comorbidities; only 3 patients (1.6%) had SAEs that were considered as possibly gefitinib-related. In the retrospective chart review cohort, 70% of patients were women; 58% were former smokers, and 30% were never-smokers; 56% were diagnosed with adenocarcinoma, and 13% were diagnosed with squamous carcinoma. Although EGFR mutational status was tested in only 17 patients (22%), it was assumed that most tumors were EGFR-mutation-positive. The median duration of gefitinib therapy was 11.1 years (7.8 years before and 3.5 years during ICAP), with 10-year and 15-year survival rates of 86% and 59%, respectively, from the initiation of therapy. A subset of long-term NSCLC survivors who were receiving gefitinib had an excellent long-term safety profile. Although it is assumed that most of these patients' tumors harbor EGFR mutations, molecular studies of available tumor specimens are planned to uncover the features that predict long-term survival.

Bromocriptine-QR (quick release) is a novel treatment for type 2 diabetes. The objective of this study is to assess the efficacy and safety of bromocriptine-QR in adults with type 2 diabetes mellitus based on randomized controlled trials published in peer-reviewed journals or as abstracts. We performed a comprehensive literature search of MEDLINE, Pubmed, Web of Science, EMBASE, and the Cochrane Library up to May 2015. Randomized controlled trials of bromocriptine-QR therapy in type 2 diabetes mellitus were eligible. Two reviewers independently assessed the eligibility of trials based on predefined inclusion criteria. Information was collected concerning basic study data, patient characteristics, efficacy and safety outcomes, and methodological quality. Bromocriptine-QR add-on therapy lowered hemoglobin A1c compared with placebo (weighted mean difference, - 6.52 mmol/mol; 95% CI, - 8.07 to - 4.97 mmol/mol). Bromocriptine-QR exhibited an increase in achieving an HbA1c level ≤ 53 mmol/mol (≤ 7.0%) (32.0 vs. 9.5%; odds ratio, 4.57; 95% CI, 2.42-8.62). Fasting plasma glucose was reduced with bromocriptine-QR compared with placebo (weighted mean difference,-1.04 mmol/l; 95% CI,-1.49 to-0.59 mmol/l). Moreover, bromocriptine-QR had neutral effects on postprandial glycemia, Body Mass Index (BMI), and lipid profile. Bromocriptine-QR had more gastrointestinal side effects of nausea and vomiting. Bromocriptine-QR had no increased risk of hypoglycemia, hypotension, or cardiovascular effects. Bromocriptine-QR therapy offers an alternative option to currently available antidiabetic agents for type 2 diabetes mellitus adults. Neither hypoglycemia nor other metabolic changes occur with this drug. More data for long-term efficacy and safety are needed for further observation. © Georg Thieme Verlag KG Stuttgart · New York.

Importance Thirty-six percent of US adults are obese and many cannot lose sufficient weight to improve health with lifestyle interventions alone. Objective Conduct a systematic review of medications currently approved in the US for obesity treatment in adults. We also discuss off-label use of medications studied for obesity and provide considerations for obesity medication use in clinical practice. Evidence Acquisition A PubMed search from inception through September, 2013 was performed to find meta-analyses, systematic reviews, and randomized, placebo-controlled trials for currently-approved obesity medications lasting ≥1y, that had a primary or secondary outcome of body weight, included ≥50 participants per group, reported ≥50% retention, and reported results on an intention-to-treat basis. Studies of medications approved for other purposes but tested for obesity treatment were also reviewed. Results Obesity medications approved for long-term use, when prescribed with lifestyle interventions, produce additional weight loss relative to placebo ranging from approximately 3% of initial weight for orlistat and lorcaserin to 9% for top-dose (15/92mg) phentermine/topiramate-ER at 1y. The proportion of patients achieving clinically-meaningful (≥5%) weight loss ranges from 37–47% for lorcaserin, 35–73% for orlistat, and 67–70% for top-dose phentermine/topiramate-ER. All three produce greater improvements in many cardiometabolic risk factors than placebo, but no obesity medication has been shown to reduce cardiovascular morbidity or mortality. Most prescriptions are for noradrenergic medications, despite their approval only for short-term use and limited data for their long-term safety and efficacy. Conclusions/Relevance Medications approved for long-term obesity treatment, when used as an adjunct to lifestyle intervention, lead to greater mean weight loss and an increased likelihood of achieving clinically-meaningful 1-year weight loss relative to placebo

Overall and long-term opioid use among older adults have increased since 1999. Less is known about opioid use in older adults in nursing homes (NHs). Cross-sectional. U.S. NHs (N = 13,522). Long-stay NH resident Medicare beneficiaries with a Minimum Data Set 3.0 (MDS) assessment between April 1, 2012, and June 30, 2012, and 120 days of follow-up (N = 315,949). We used Medicare Part D claims to measure length of opioid use in the 120 days from the index assessment (short-term: ≤30 days, medium-term: >30-89 days, long-term: ≥90 days), adjuvants (e.g., anticonvulsants), and other pain medications (e.g., corticosteroids). MDS assessments in the follow-up period were used to measure nonpharmacological pain management use. Modified Poisson models were used to estimate adjusted prevalence ratios (aPR) and 95% confidence intervals (CI) for age, gender, race and ethnicity, cognitive and physical impairment, and long-term opioid use. Of all long-stay residents, 32.4% were prescribed any opioid, and 15.5% were prescribed opioids long-term. Opioid users (versus nonusers) were more commonly prescribed pain adjuvants (32.9% vs 14.9%), other pain medications (25.5% vs 11.0%), and nonpharmacological pain management (24.5% vs 9.3%). Long-term opioid use was higher in women (aPR = 1.21, 95% CI = 1.18-1.23) and lower in racial and ethnic minorities (non-Hispanic blacks vs whites: APR = 0.93, 95% CI = 0.90-0.94) and those with severe cognitive impairment (vs no or mild impairment, aPR = 0.82, 95% CI = 0.79-0.83). One in seven NH residents was prescribed opioids long-term. Recent guidelines on opioid prescribing for pain recommend reducing long-term opioid use, but this is challenging in NHs because residents may not benefit from nonpharmacological and nonopioid interventions. Studies to address concerns about opioid safety and effectiveness (e.g., on pain and functional status) in NHs are needed. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics

The first recombinant factor VIII (rFVIII) product was launched in China in 2007. However, until now, no study has been conducted to describe the efficacy and safety of prophylaxis with rFVIII in Chinese pediatric patients with hemophilia A (HA). To summarize the efficacy and safety data on prophylaxis with rFVIII in Chinese pediatric patients with HA. ReCARE (Retrospective study in Chinese pediatric hemophilia A patients with rFVIII contained regular prophylaxis) was a retrospective study conducted in 12 hemophilia treatment centers (HTCs) across China. The primary endpoints included reduction in annualized bleeding rate (ABR); the secondary endpoints included evaluation of joint function (number and sites of target joints) using Gilbert score and Hemophilia Joint Health Score (HJHS), quality of life (QoL) and factors affecting treatment choices. Safety assessment of rFVIII was also conducted. We analyzed a total of 183 male pediatric patients (mean age, 7.1 ± 4.23 years) who received prophylaxis between 1 November 2007 and 31 May 2013. Compared with baseline, prophylaxis with rFVIII significantly reduced overall annualized joint bleed rate (AJBR) (p < .001) and ABR (p < .001). Inhibitor formation was reported in 5 (2.7%) patients and hemarthrosis was reported in 1 patient. The mean number of target joints was positively related to age (p < .001) and weight (p = .003) at baseline. Responses from survey questionnaires reported that effective bleeding control, joint protection, improvement in quality of life, favorable medical insurance policies, and economic capability were reasons for choosing prophylaxis. Prophylaxis with rFVIII reduced bleeding and number of target joints, even with a low-dose regimen, in Chinese pediatric patients with HA. Other than the efficacy and safety, factors such as poor disease control, improved economic stability and stable financial support made prophylaxis as an attractive treatment option.

The aim was to describe the status of patients with urea cycle disorders (UCD) at the latest long-term clinical follow-up of treatment with a new taste-masked formulation of sodium phenylbutyrate (NaPB) granules (Pheburane). These patients are a subset of those treated under a cohort temporary utilisation study (ATU) previously reported and now followed for 2 years. From a French cohort temporary utilization authorization (ATU) set up to monitor the use of Pheburane on a named-patient basis in UCD patients in advance of its marketing authorization, a subset of patients were followed up in the long term. Data on demographics, dosing characteristics of NaPB, concomitant medications, adverse events and clinical outcomes were collected at a follow-up visit after 1-2 years of treatment with the drug administered under marketing conditions. This paper reports on the subset of patients who were included in further long-term follow-up at the principal recruiting metabolic reference center involved in the original cohort. No episode of metabolic decompensation was observed over a treatment period ranging from 8 to 30 months with Pheburane, and the range of ammonia and glutamine levels continued to improve and remained within the normal range, thus adding valuable longer-term feedback to the original ATU report. In all, no adverse events were reported with Pheburane treatment. These additional data demonstrate the maintenance of the safety and efficacy of Pheburane over time. The recently developed taste-masked formulation of NaPB granules (Pheburane) improved the quality of life for UCD patients. The present post-marketing report on the use of the product confirms the original observations of improved compliance, efficacy and safety with this taste-masked formulation of NaPB.

High myopia is known to be a risk factor for long-term regression after laser refractive surgery. There have been few studies about the correction of moderate myopias that did not need retreatment after long-term follow-up. We evaluated 10 years of change in visual acuity and refractive power in eyes with moderate myopia after laser refractive surgery. We included patients that had undergone laser in situ keratomileusis (LASIK) or laser-assisted subepithelial keratectomy (LASEK) to correct their myopia and that had at least 10 years of follow-up. We evaluated the stability of visual acuity in terms of safety, efficacy, and refractive changes at examinations 6 months and 1, 2, 5, 7, and 10 years after surgery. The study evaluated 62 eyes (36 eyes in LASIK patients and 26 eyes in LASEK patients). In both groups, the efficacy index tended to decrease, and it was consistently higher in the LASEK group compared to the LASIK group over the 10 years of follow-up. The safety index improved over 10 years and was always higher than 0.9 in both groups. The difference between the spherical equivalent at 6 months postoperatively and later periods was statistically significant after 5, 7, and 10 years in both groups (LASIK, p = 0.036, p = 0.003, and p < 0.001, respectively; LASEK, p = 0.006, p = 0.002, and p = 0.001, respectively). Ten years after surgery,26 eyes (66.7%) in the LASIK group and 19 eyes (73.1%) in the LASEK group had myopia greater than 1 diopter. In comparison with the thickness at 6 months postoperatively, central corneal thickness was significantly increased after 5, 7, and 10 years in both LASIK and LASEK groups (LASIK, p < 0.001, p < 0.001, and p < 0.001, respectively; LASEK, p = 0.01, p < 0.001, and p < 0.001, respectively). Moderately myopic eyes showed progressive myopic shifting and corneal thickening after LASIK and LASEK during 10 years of follow-up. We also found that early refractive regression may indicate the long-term refractive outcome.

A pilot self-efficacy education programme was conducted to assess the feasibility, acceptability and potential impact of the self-efficacy education programme on improving foot self-care behaviour among older patients with diabetes in a public long-term care institution. A prequasi-experimental and postquasi-experimental study was conducted in a public long-term care institution in Selangor, Malaysia. Patients with diabetes aged 60 years and above who fulfilled the selection criteria were invited to participate in this programme. Four self-efficacy information sources; performance accomplishments, vicarious experience, verbal persuasion and physiological information were translated into programme interventions. The programme consisted of four visits over a 12-week period. The first visit included screening and baseline assessment and the second visit involved 30 min of group seminar presentation. The third and fourth visits entailed a 20-min one-to-one follow-up discussion and evaluation. A series of visits to the respondents was conducted throughout the programme. The primary outcome was foot self-care behaviour. Foot self-efficacy (efficacy-expectation), foot care outcome expectation, knowledge of foot care, quality of life, fasting blood glucose and foot condition were secondary outcomes. Data were analysed with descriptive and inferential statistics (McNemar's test and Wilcoxon signed-rank test) using the Statistical Package for the Social Sciences V.20.0. Fifty-two residents were recruited but only 31 met the inclusion criteria and were included in the analysis at baseline and at 12 weeks postintervention. The acceptability rate was moderately high. At postintervention, foot self-care behaviour (p<0.001), foot self-efficacy (efficacy-expectation), (p<0.001), foot care outcome expectation (p<0.001), knowledge of foot care (p<0.001), quality of life (physical symptoms) (p=0.003), fasting blood glucose (p=0.010), foot hygiene (p=0.030) and anhydrosis (p=0

Objective A pilot self-efficacy education programme was conducted to assess the feasibility, acceptability and potential impact of the self-efficacy education programme on improving foot self-care behaviour among older patients with diabetes in a public long-term care institution. Method A prequasi-experimental and postquasi-experimental study was conducted in a public long-term care institution in Selangor, Malaysia. Patients with diabetes aged 60 years and above who fulfilled the selection criteria were invited to participate in this programme. Four self-efficacy information sources; performance accomplishments, vicarious experience, verbal persuasion and physiological information were translated into programme interventions. The programme consisted of four visits over a 12-week period. The first visit included screening and baseline assessment and the second visit involved 30 min of group seminar presentation. The third and fourth visits entailed a 20-min one-to-one follow-up discussion and evaluation. A series of visits to the respondents was conducted throughout the programme. The primary outcome was foot self-care behaviour. Foot self-efficacy (efficacy-expectation), foot care outcome expectation, knowledge of foot care, quality of life, fasting blood glucose and foot condition were secondary outcomes. Data were analysed with descriptive and inferential statistics (McNemar's test and Wilcoxon signed-rank test) using the Statistical Package for the Social Sciences V.20.0. Results Fifty-two residents were recruited but only 31 met the inclusion criteria and were included in the analysis at baseline and at 12 weeks postintervention. The acceptability rate was moderately high. At postintervention, foot self-care behaviour (p<0.001), foot self-efficacy (efficacy-expectation), (p<0.001), foot care outcome expectation (p<0.001), knowledge of foot care (p<0.001), quality of life (physical symptoms) (p=0.003), fasting blood glucose (p=0.010), foot hygiene (p=0

Validation of program effectiveness is essential in justifying school-based injury prevention education. Although Risk Watch (RW) targets burn, fire, and life safety, its effectiveness has not been previously evaluated in the medical literature. Between 2007 and 2012, a trained fire service public educator (FSPE) taught RW to all second grade students in one public school district. The curriculum was delivered in 30-minute segments for 9 consecutive weeks via presentations, a safety smoke house trailer, a model-sized hazard house, a student workbook, and parent letters. A written pre-test (PT) was given before RW started, a post-test (PT#1) was given immediately after RW, and a second post-test (PT#2) was administered to the same students the following school year (ranging from 12 to 13 months after PT). Students who did not complete the PT or at least one post-test were excluded. Comparisons were made by paired t-test, analysis of variance, and regression analysis. After 183 (8.7%) were excluded for missing tests, 1,926 remaining students scored significantly higher (P = .0001) on PT#1 (mean 14.8) and PT#2 (mean 14.7) than the PT (mean 12.1). There was 1 FSPE and 36 school teachers with class size ranging from 10 to 27 (mean 21.4). Class size was not predictive of test score improvement (R = 0%), while analysis of variance showed that individual teachers trended toward some influence. This 6-year prospective study demonstrated that the RW program delivered by an FSPE effectively increased short-term knowledge and long-term retention of fire/life safety in early elementary students. Collaborative partnerships are critical to preserving community injury prevention education programs.

PurposeTo evaluate the safety, efficacy, and long-term results of endovascular stent graft placement for ureteroarterial fistula (UAF).MethodsWe retrospectively analyzed stent graft placement for UAF performed at our institution from 2004 to 2012. Fistula location was assessed by contrast-enhanced computed tomography (CT) and angiography, and freedom from hematuria recurrence and mortality rates were estimated.ResultsStent graft placement for 11 UAFs was performed (4 men, mean age 72.8 {+-} 11.6 years). Some risk factors were present, including long-term ureteral stenting in 10 (91 %), pelvic surgery in 8 (73 %), and pelvic radiation in 5 (45 %). Contrast-enhanced CT and/or angiography revealed fistulamore » or encasement of the artery in 6 cases (55 %). In the remaining 5 (45 %), angiography revealed no abnormality, and the suspected fistula site was at the crossing area between urinary tract and artery. All procedures were successful. However, one patient died of urosepsis 37 days after the procedure. At a mean follow-up of 548 (range 35-1,386) days, 4 patients (36 %) had recurrent hematuria, and two of them underwent additional treatment with secondary stent graft placement and surgical reconstruction. The hematuria recurrence-free rates at 1 and 2 years were 76.2 and 40.6 %, respectively. The freedom from UAF-related and overall mortality rates at 2 years were 85.7 and 54.9 %, respectively.ConclusionEndovascular stent graft placement for UAF is a safe and effective method to manage acute events. However, the hematuria recurrence rate remains high. A further study of long-term results in larger number of patients is necessary.« less

Rubber band ligation is an effective treatment for hemorrhoids. A retrospective analysis was performed to evaluate its short and long-term efficacy. From 2000 to 2008, 254 outpatients with II- degree and 114 with III-degree hemorrhoids underwent rubber band ligation. Two or three hemorrhoids were ligated per session. Each haemorrhoid was ligated with two rubber bands through a ligator. All patients were visited after two months and followed up through a telephone after two and eleven years. Twenty-four or forty-eight hours post treatment, 41% of patients had mild-moderate pain. Four patients showed severe pain and required for haemorrhoidectomy within a few days. Only 2% of patients experienced self-limiting rectal bleeding after one week and 6% of patients had an additional ligation within two months. Two months later, 92% of II-degree patients and 76% of III-degree patients showed no residual symptoms. After two and eleven years, the history of 314 patients (85%) were obtained, of them, 70% was asymptomatic, 27% had some residual symptoms of occasional bleeding and prolapse, and 3% needed further surgery. Rubber band ligation is an efficient, cost-effective and simple outpatient procedure for the second and third degree hemorrhoids with minimal complications.

Anticonvulsants and antidepressants are mostly used in management of painful diabetic neuropathy (PDN). However there are few direct comparisons between drugs of these classes, making evidence-based decision-making in the treatment of painful diabetic neuropathy difficult. This study aimed to perform a network meta-analysis and benefit-risk analysis to evaluate the comparative efficacy and safety of these drugs in PDN treatment. Comparative effectiveness study. Medical Education and Research facility in India. A comprehensive data search was done in PubMed, Cochrane, and Embase up to August 2012. We then systematically reviewed the studies which compared any of 6 drugs for the management of PDN: amitriptyline, duloxetine, gabapentin, pregabalin, valproate, and venlafaxine or any of their combinations. We performed a random-effects network meta-analysis to rank treatments in terms of efficacy and safety. We chose the number of patients experiencing = 50% reduction in pain and number of patient withdrawals due to adverse events (AE) as primary outcomes for efficacy and safety, respectively. We also performed benefit-risk analysis, taking efficacy outcome as benefit and safety outcome as risk. Analysis was intention-to-treat. We included 21 published trials in the analysis. Duloxetine, gabapentin, pregabalin, and venlafaxine were shown to be significantly efficacious compared to placebo with odds ratios (OR) of 2.12, 3.98, 2.78, and 4.43, respectively. Amitriptyline (OR: 7.03, 95% confidence interval [CI]: 1.87, 29.05) and duloxetine (OR: 3.26, 95% CI: 1.04, 9.97) caused more withdrawals than gabapentin. The ranking order of efficacy was gabapentin, venlafaxine, pregabalin, duloxetine/gabapentin, duloxetine, amitriptyline, and placebo and the ranking order of safety was placebo, gabapentin, pregabalin, venlafaxine, duloxetine/gabapentin combination, duloxetine, and amitriptyline. Benefit-risk balance favored the order: gabapentin, venlafaxine, pregabalin, duloxetine

Conjugated estrogens (CE) and Bazedoxifene (BZA) combination is used to alleviate menopause-associated symptoms in women. CE+BZA undergo first-pass-metabolism in the liver and deconjugation by gut microbiome via β-glucuronidase (GUS) enzyme inside the distal gut. To date, the impact of long-term exposure to CE+BZA on the gut microbiome or GUS activity has not been examined. Our study using an ovariectomized mouse model showed that CE+BZA administration did not affect the overall cecal or fecal microbiome community except that it decreased the abundance of Akkermansia, which was identified as a fecal biomarker correlated with weight gain. The fecal GUS activity was reduced significantly and was positively correlated with the abundance of Lactobacillaceae in the fecal microbiome. We further confirmed in Escherichia coli K12 and Lactobacillus gasseri ADH that Tamoxifen-, 4-hydroxy-Tamoxifen- and Estradiol-Glucuronides competed for GUS activity. Our study for the first time demonstrated that long-term estrogen supplementation directly modulated gut microbial GUS activity. Our findings implicate that long-term estrogen supplementation impacts composition of gut microbiota and microbial activity, which affects estrogen metabolism in the gut. Thus, it is possible to manipulate such activity to improve the efficacy and safety of long-term administered estrogens for postmenopausal women or breast cancer patients.

Radiofrequency current energy (RFC) ablation is still considered as the gold standard for atrioventricular nodal reentrant tachycardia (AVNRT). Success-rates for AVNRT ablation vary irrespective of the ablation technology and strategy. This study aimed to access safety, efficacy, and long-term outcome of RFC catheter ablation for the treatment of AVNRT in children and adolescents aged < 19 years with special focus on modulation versus ablation of the AV nodal slow pathway (SP). A total number of 1143 patients (pts) < 19 years were referred for invasive electrophysiological testing due to paroxysmal supraventricular tachycardia (SVT). Diagnosis of AVNRT was confirmed in 412 pts, and RFC-guided ablation was attempted in 386 pts (age 13.0 ± 3.5 years). No permanent complications were observed. RFC application resulted in SP-ablation in 171/386 (44.3%) and in SP modulation in 208/386 (53.9%) children, whereas attempts for RFC treatment failed in 7 pts. Follow-up was completed for 396/412 patients (96.1%). Within a mean follow-up period of 54.9 ± 39.7 months, in 51/379 pts (13.5%) AVNRT recurrence was observed. The median time until tachycardia recurrence was 19.5 months. No difference for AVNRT recurrence was found comparing SP ablation versus SP modulation (p > 0.05), whereas the recurrence rate was significantly higher in patients with non-inducible SVT and therefore empiric SP treatment as compared to patients with inducible AVNRT (p = 0.01). RFC-guided ablation for AVNRT in children and adolescents is safe and leads to an acceptable long-term freedom from recurrences. SP modulation and SP ablation resulted in comparable acute and long-term success rates. Late AVNRT recurrences can occur even after years of freedom from tachycardia-related symptoms.

Chronic migraine is a common, highly disabling, underdiagnosed and undertreated entity of migraine. It affects 0.9%-2.2% of the general adult population. The present paper overviews the preclinical and clinical data regarding the therapeutic effect of onabotulinumtoxinA in chronic migraineurs. A literature search was conducted in the database of PubMed up to 20 May 2015 for articles related to the pathomechanism of chronic migraine, the mode of action, and the efficacy, safety and tolerability of onabotulinumtoxinA for the preventive treatment of chronic migraine. The pathomechanism of chronic migraine has not been fully elucidated. The mode of action of onabotulinumtoxinA in the treatment of chronic migraine is suggested to be related to the inhibition of the release of calcitonin gene-related peptide and substance P in the trigeminovascular system. Randomized clinical trials demonstrated that long-term onabotulinumtoxinA fixed-site and fixed-dose (155-195 U) intramuscular injection therapy was effective and well tolerated for the prophylactic treatment of chronic migraine. Chronic migraine is a highly devastating entity of migraine. Its exact pathomechanism is unrevealed. Two-third of chronic migraineurs do not receive proper preventive medication. Recent clinical studies revealed that onabotulinumtoxinA was an efficacious and safe treatment for chronic migraine.

Objective. In the US alone, there are approximately 185 000 cases of limb amputation annually, which can reduce the quality of life for those individuals. Current prosthesis technology could be improved by access to signals from the nervous system for intuitive prosthesis control. After amputation, residual peripheral nerves continue to convey motor signals and electrical stimulation of these nerves can elicit sensory percepts. However, current technology for extracting information directly from peripheral nerves has limited chronic reliability, and novel approaches must be vetted to ensure safe long-term use. The present study aims to optimize methods to establish a test platform using rodent model to assess the long term safety and performance of electrode interfaces implanted in the peripheral nerves. Approach. Floating Microelectrode Arrays (FMA, Microprobes for Life Sciences) were implanted into the rodent sciatic nerve. Weekly in vivo recordings and impedance measurements were performed in animals to assess performance and physical integrity of electrodes. Motor (walking track analysis) and sensory (Von Frey) function tests were used to assess change in nerve function due to the implant. Following the terminal recording session, the nerve was explanted and the health of axons, myelin and surrounding tissues were assessed using immunohistochemistry (IHC). The explanted electrodes were visualized under high magnification using scanning electrode microscopy (SEM) to observe any physical damage. Main results. Recordings of axonal action potentials demonstrated notable session-to-session variability. Impedance of the electrodes increased upon implantation and displayed relative stability until electrode failure. Initial deficits in motor function recovered by 2 weeks, while sensory deficits persisted through 6 weeks of assessment. The primary cause of failure was identified as lead wire breakage in all of animals. IHC indicated myelinated and unmyelinated axons

To evaluate the long-term safety and efficacy of tofogliflozin as an add-on treatment to insulin over 52 weeks. This 52-week, multicentre, Phase 4 study consisted of a 16-week, randomized, double-blind, placebo-controlled phase and a 36-week open label extension phase (NCT02201004). Japanese patients with type 2 diabetes mellitus, aged 20 to 75 years, with suboptimal glycaemic control (7.5%-10.5%) receiving insulin monotherapy (basal-bolus, bolus, premix [low and high] and basal) or receiving combination therapy with basal insulin and dipeptidyl peptidase-4 inhibitor were eligible for participation. Patients who received tofogliflozin throughout the study (52 weeks) were referred to as the 'tofo-tofo group' and patients who received placebo and tofogliflozin (36 weeks) were referred to as the 'pla-tofo group'. A total of 210 patients received treatment per randomization. Hypoglycaemia was the most common treatment-emergent adverse event (AE) (42.9% in the tofo-tofo group and 29.4% in the pla-tofo group). Patients reported genital infection, urinary tract infection, excessive urination and AEs related to volume depletion (2.1%, 2.1%, 7.1% and 10.0% of patients in the tofo-tofo group, and 0%, 1.5%, 2.9% and 7.4% of patients in the pla-tofo group, respectively). Mean HbA1c and body weight at baseline (mean changes ± standard error from baseline to Week 52) in the tofo-tofo and pla-tofo groups were 8.53% (-0.76% ± 0.077) and 8.40% (-0.73% ± 0.102); 68.84 kg (-1.52 kg ± 0.207) and 72.24 kg (-2.13 kg ± 0.313), respectively. This study demonstrates the safety and efficacy of tofogliflozin as add-on to insulin therapy in type 2 diabetes mellitus patients, offering a new therapeutic solution to diabetes management. © 2018 The Authors.

This paper investigate how long will the historical traffic flow time series keep efficacious to forecast the future. In this frame, we collect the traffic flow time series data with different granularity at first. Then, using the modified rescaled range analysis method, we analyze the long memory property of the traffic flow time series by computing the Hurst exponent. We calculate the long-term memory cycle and test its significance. We also compare it with the maximum Lyapunov exponent method result. Our results show that both of the freeway traffic flow time series and the ground way traffic flow time series demonstrate positively correlated trend (have long-term memory property), both of their memory cycle are about 30 h. We think this study is useful for the short-term or long-term traffic flow prediction and management.

Critics of the drug safety system have discussed many different potential reforms, ranging from mandatory registration of clinical trials to increasing the power of regulatory agencies, but few have discussed one of the most important ways of enhancing safety: increasing the number of long-term studies of medications. Long-term studies of the risks and benefits of drugs can provide useful information for regulators, healthcare professionals, and patients. Government funding agencies should lead the effort to conduct long-term studies of drugs, but private companies should also be required to lend financial support. Because cost-effectiveness is likely to be an important consideration in conducting this research, funding agencies should focus, at first, on drugs that are used to treat common, chronic conditions.

Presently, orthopedic and oral/maxillofacial implants represent a combined $2.8 billion market, a figure expected to experience significant and continued growth. Although traditional permanent implants have been proved clinically efficacious, they are also associated with several drawbacks, including secondary revision and removal surgeries. Non-permanent, biodegradable implants offer a promising alternative for patients, as they provide temporary support and degrade at a rate matching tissue formation, and thus, eliminate the need for secondary surgeries. These implants have been in clinical use for nearly 25 years, competing directly with, or maybe even exceeding, the performance of permanent implants. The initial implantation of biodegradable materials, as with permanent materials, mounts an acute host inflammatory response. Over time, the implant degradation profile and possible degradation product toxicity mediate long-term biodegradable implant-induced inflammation. However, unlike permanent implants, this inflammation is likely to cease once the material disappears. Implant-mediated inflammation is a critical determinant for implant success. Thus, for the development of a proactive biodegradable implant that has the ability to promote optimal bone regeneration and minimal detrimental inflammation, a thorough understanding of short- and long-term inflammatory events is required. Here, we discuss an array of biodegradable orthopedic implants, their associated short- and long- term inflammatory effects, and methods to mediate these inflammatory events. PMID:22043969

The somatostatin analog lanreotide Autogel has proven to be efficacious for treating acromegaly in international studies and in clinical practices around the world. However, its efficacy in Japanese patients has not been extensively evaluated. We examined the dose-response relationship and long-term efficacy and safety in Japanese patients with acromegaly or pituitary gigantism. In an open-label, parallel-group, dose-response study, 32 patients (29 with acromegaly, 3 with pituitary gigantism) received 5 injections of 60, 90, or 120 mg of lanreotide Autogel over 24 weeks. Four weeks after the first injection, 41% of patients achieved serum GH level of <2.5 ng/mL and insulin-like growth factor-I (IGF-I) level was normalized in 31%. Values at Week 24 were 53% for GH and 44% for IGF-I. Dose-dependent decreases in serum GH and IGF-I levels were observed with dose-related changes in pharmacokinetic parameters. In an open-label, long-term study, 32 patients (30 with acromegaly, 2 with pituitary gigantism) received lanreotide Autogel once every 4 weeks for a total of 13 injections. Dosing was initiated with 90 mg and adjusted according to clinical responses at Weeks 16 and/or 32. At Week 52, 47% of patients had serum GH levels of <2.5 ng/mL and 53% had normalized IGF-I level. In both studies, acromegaly symptoms improved and treatment was generally well tolerated although gastrointestinal symptoms and injection site induration were reported. In conclusion, lanreotide Autogel provided early and sustained control of elevated GH and IGF-I levels, improved acromegaly symptoms, and was well tolerated in Japanese patients with acromegaly or pituitary gigantism.

As part of the work scope set in the French law on high level long lived waste R&D passed in 1991, CEA is conducting a research program to establish the scientific basis and assess the feasibility of long term storage as an option for the safe management of nuclear waste for periods as long as centuries. This goal is a significant departure from the current industrial practice where storage facilities are usually built to last only a few decades. From a technical viewpoint such an extension in time seems feasible provided care and maintenance is exercised. Considering such long periodsmore » of time, the risk for Society of loosing oversight and control of such a facility is real, which triggers the question of whether and how long term storage safety can be actually achieved. Therefore CEA commissioned a study (1) in which MUTADIS Consultants (2) and CEPN (3) were both involved. The case study looks into several past and actual human enterprises conducted over significant periods o f time, one of them dating back to the end of the 18th century, and all identified out of the nuclear field. Then-prevailing societal behavior and organizational structures are screened out to show how they were or are still able to cope with similar oversight and control goals. As a result, the study group formulated a set of performance criteria relating to issues like responsibility, securing funds, legal and legislative implications, economic sustainable development, all being areas which are not traditionally considered as far as technical studies are concerned. These criteria can be most useful from the design stage onward, first in an attempt to define the facility construction and operating guiding principles, and thereafter to substantiate the safety case for long term storage and get geared to the public dialogue on that undertaking should it become a reality.« less

The objective of this study was to investigate the safety and efficacy of subcutaneous (SC) and intravenous (IV) tanezumab administration in osteoarthritis (OA) patients. Study 1027 (NCT01089725), a placebo-controlled trial, evaluated the efficacy of SC tanezumab (ie, 2.5, 5, and 10 mg) and the therapeutic equivalence of 10 mg tanezumab given subcutaneously versus intravenously every 8 weeks in the symptomatic treatment of OA. Coprimary endpoints were: change from baseline in Western Ontario and McMaster Universities Osteoarthritis index (WOMAC) Pain and Physical Function indices, and Patient's Global Assessment (PGA) of OA. Study 1043 (NCT00994890) was a long-term, noncontrolled safety study of tanezumab (ie, 2.5, 5, and 10 mg) subcutaneously administered every 8 weeks. Both studies were discontinued prematurely due to a US Food and Drug Administration partial clinical hold. Due to the clinical hold, Study 1027 was underpowered, and no statistical analyses were performed. Mean (standard error [SE]) change from baseline to week 8 in WOMAC Pain in tanezumab groups ranged from -3.59 (0.26) to -3.89 (0.32), versus -2.74 (0.25) with placebo. Mean (SE) change from baseline to week 8 in WOMAC Physical Function ranged from -3.13 (0.25) to -3.51 (0.28) with tanezumab and was -2.26 (0.24) with placebo. PGA mean (SE) change from baseline to week 8 ranged from -0.90 (0.11) to -1.08 (0.12) with tanezumab and was -0.78 (0.10) with placebo. Similar effectiveness was associated with tanezumab in Study 1043. Few patients in either study (1.4%-5.2%) discontinued due to adverse events. Five patients required total joint replacements in Study 1027 (placebo, n=2 [2.8%]; tanezumab 2.5 mg, n=3 [4.1%]) and 34 patients in Study 1043 (tanezumab 2.5 mg, n=11 [4.8%]; tanezumab 5 mg, n=8 [3.6%]; tanezumab 10 mg, n=15 [6.6%]). Preliminary results show similar efficacy and safety for both SC and IV administration of tanezumab based on the direct comparisons reported here and indirect

The rationale for treatment of patients with port-wine stain (PWS) birthmarks has focused on the belief that eventual soft-tissue hypertrophy and negative psychological effects might be diminished or avoided. Pulsed-dye laser (PDL) therapy has become widely accepted as the treatment of choice for PWS, and a variety of studies have been conducted that evaluate its short-term efficacy. Long-term data regarding outcome and patient satisfaction are lacking. Our objective was to evaluate the long-term efficacy of pulsed-dye laser therapy from the patient's perspective. A survey was mailed to all patients or parents of minor patients whose last known laser treatment was performed between January 1, 1989, and January 1, 1996. Patients were asked to quantify changes in their PWS as well as their psychological well-being. A formal qualitative analysis was performed on their written comments as well. A total of 164 surveys were mailed to the most recent address available by the patient record. Fifty-two surveys were returned as undeliverable, and 55 evaluable surveys were returned, yielding a 49% overall return rate for patients who could be located. The mean age of respondents was 28.8 years, 96% of whom were white and 62% female. The mean number of years since last treatment was 7.04. The vast majority of patients noted little or no change in texture, height, or dimension of their PWS, whereas 62% noted color improvement. A majority or patients (60%) worried less about their appearance after treatment, whereas a similar number (61%) believed their ability to make friends or meet others was unaffected by treatment. Only 19% thought others looked at or treated them differently because of their PWS. Overall, 48% of patients indicated satisfaction with treatment, 24% dissatisfaction, and 28% neutral. On a 10-point scale indicating their likelihood of recommending treatment to someone similarly affected, the mean score was 7.42. Men were significantly and consistently less

In an open-label extension of a randomized, double-blind clinical trial, the long-term efficacy and tolerability of a fixed combination of 160 mg Sabal fruit extract WS 1473 and 120 mg Urtica root extract WS 1031 per capsule (PRO 160/120) were investigated in elderly men with moderate or severe lower urinary tract symptoms (LUTS) caused by benign prostatic hyperplasia (BPH). Two hundred and fifty-seven patients were randomly treated with 2 x 1 capsule/day PRO 160/120 or placebo for 24 weeks, followed by a 24-week control period and a 48-week follow-up period in which all patients received PRO 160/120. Efficacy measures included the assessment of LUTS [International Prostate Symptom Score ((I-PSS) self-rating questionnaire] and uroflow and sonographic parameters. Two hundred and nineteen subjects participated in the follow-up. Between baseline and end of observation (week 96) the I-PSS total score was reduced by 53% (P < 0.001), peak and average urinary flow increased by 19% (P < 0.001), and residual urine volume decreased by 44% (P = 0.03). The incidence of adverse events during follow-up was one in 1,181 treatment days; in only one event a causal relationship with intake of PRO 160/120 could not be excluded. Treatment with PRO 160/120 thus provides a clinically relevant benefit over a period of 96 weeks.

The objective of this study was to assess the efficacy and safety of bupivacaine compared with lidocaine in local anaesthesia in dental treatment. Medline, Cochrane Central Register of Controlled Trials, EMBASE, Chinese BioMedical Literature Database, China National Knowledge Infrastructure, and the World Health Organisation (WHO) International Clinical Trials Registry Platform were searched electronically. Relevant journals and references of studies included were hand-searched for randomised controlled trials comparing bupivacaine with lidocaine in terms of efficacy and safety. Sixteen studies were included, of which nine had low, six had moderate and one had high risk of bias. In comparison with 2% lidocaine plus 1:100,000 adrenaline, 0.5% bupivacaine plus 1:200,000 adrenaline showed a higher success rate in inflamed pulp (P = 0.03) but a lower success rate in vital pulp (P < 0.00001), a lower percentage of patients using postoperative analgesics (P < 0.00001), a longer onset times of pulpal anaesthesia and a longer duration of pulpal anaesthesia (P < 0.00001). In comparison with 2% lidocaine plus 1:80,000 adrenaline, 0.75% bupivacaine plus 1:200,000 adrenaline had same level of success rate (P = 0.29), and was better in postoperative pain control (P = 0.001) while 0.75% levobupivacaine had same level of postoperative pain control (P = 0.16); 0.5% levobupivacaine had higher success rate (P = 0.04) and was better in postoperative pain control (P = 0.001) than 2% lidocaine. There was no statistically significance in adverse events between two groups. Given the efficacy and safety, the bupivacaine group is better than the lidocaine group in dental operations that take a relatively long time, especially in endodontic treatments or where there is a need for postoperative pain management. © 2013 FDI World Dental Federation.

The neuropharmacology of ADHD drugs in vivo: insights on efficacy and safety.

Heal, D J; Cheetham, S C; Smith, S L

2009-12-01

Results from in vivo techniques, especially intracerebral microdialysis in freely-moving rats, have provided insights into potential mechanisms responsible for the efficacy and safety of catecholaminergic drugs for ADHD treatment. The drugs reviewed come from distinct pharmacological classes: psychostimulant releasing agents, eg d-amphetamine; psychostimulant reuptake inhibitors, eg dl-threo-methylphenidate (dl-MPH), and non-stimulant reuptake inhibitors, eg atomoxetine. Psychostimulants, which currently deliver the best efficacy in treating ADHD, exhibit the following characteristics on extraneuronal catecholamine concentrations in rodent brain in vivo: 1) They enhance the efflux and function of both noradrenaline and dopamine in the central nervous system. 2) The increase of dopamine efflux that they produce is not limited to cortical regions. 3) They have a rapid onset of action with no ceiling on drug effect. d-Amphetamine has a mechanism independent of neuronal firing rate, displacing intraneuronal stores of catecholamines, delaying their reuptake and inhibiting catabolism by monoamine oxidase. dl-MPH has an enigmatic, extraneuronal action that is neuronal firing rate-dependent and reuptake transporter-mediated, yet paradoxically, almost as powerful as that of d-amphetamine. In safety terms, these powerful catecholaminergic effects also make the psychostimulants liable for abuse. Since efficacy and safety derive from the same pharmacological mechanisms, it has not yet been possible to separate these two components. However, the development of once-daily psychostimulant formulations and a prodrug, lisdexamfetamine, has improved patient compliance and markedly reduced scope for their diversion/abuse. This review will discuss the in vivo pharmacological profiles of approved catecholaminergic drugs for treatment of ADHD and implications for their clinical efficacy and abuse liability.

In this study, we wished to compare the long-term outcome of (medication-free) panic disorder with agoraphobia patients randomized to cognitive or guided mastery therapy. Thirty-one (67.4%) of 46 patients who had completed treatment were followed up about 18 years after end of treatment. In the combined sample and using intent-to-follow-up analyses, there were large within-group effect sizes of -1.79 and -1.63 on the primary interview-based and self-report outcome measures of avoidance of situations when alone, and 56.5% no longer had a panic disorder and/or agoraphobia diagnosis. No outcome differences between the two treatments emerged. Guided mastery was associated with greater beneficial changes in catastrophic beliefs and self-efficacy. For two of five outcome measures, more reduction in panic-related beliefs about physical and mental catastrophes from pre- to post-treatment predicted lower level of anxiety from post-treatment to 18-year follow-up when the effect of treatment changes in (a) self-efficacy and (b) anxiety was controlled. However, for one of the outcome measures, this effect attenuated with time. Copyright © 2014 John Wiley & Sons, Ltd. The results suggest that the very-long-term outcome of both cognitive therapy and guided mastery therapy for agoraphobia is positive. The results support the role of catastrophic beliefs as mediator of change. The pattern of results suggests that learning processes other than catastrophic beliefs may be important for long-term outcome as well. Copyright © 2014 John Wiley & Sons, Ltd.

In the pivotal 24-week, phase III, placebo-controlled trial, teduglutide significantly reduced parenteral support (PS) requirements in patients with short bowel syndrome (SBS). STEPS-2 was a 2-year, open-label extension of that study designed to evaluate long-term safety and efficacy of teduglutide. Enrolled patients had completed 24 weeks of either teduglutide (TED/TED) or placebo (PBO/TED) in the initial placebo-controlled study or qualified for that study, but were not treated (NT/TED) because of full enrollment. Patients received subcutaneous teduglutide 0.05 mg/kg/day for up to 24 months (NT/TED and PBO/TED) or up to 30 months (TED/TED). Clinical response was defined as 20-100% reduction from baseline in weekly PS volume; baseline was considered the beginning of teduglutide treatment in the initial placebo-controlled study (TED/TED) or STEPS-2 (NT/TED and PBO/TED). Descriptive statistics summarized changes in efficacy and safety variables. Of 88 enrolled patients, 65 (74%) completed STEPS-2. The most common treatment-emergent adverse events were abdominal pain (34%), catheter sepsis (28%), and decreased weight (25%). Mean weight, body mass index, and serum albumin remained stable. In patients who completed the study, clinical response was achieved in 28/30 (93%) TED/TED, 16/29 (55%) PBO/TED, and 4/6 (67%) NT/TED patients. Mean PS volume reductions from baseline were 7.6 (66%), 3.1 (28%), and 4.0 (39%) l/week in the TED/TED, PBO/TED, and NT/TED groups, respectively. Thirteen patients achieved full enteral autonomy. In patients with SBS, long-term teduglutide treatment resulted in sustained, continued reductions in PS requirements. Overall health and nutritional status was maintained despite PS reductions.

The aim of this work was to perform a pilot study on the safety and efficacy of nanoparticle formulation for cosmetic application. The encapsulated actives in the nanoparticles were a blend of coenzyme Q10, retinyl palmitate, tocopheryl acetate, grape seed oil and linseed oil. The nanoparticle suspension was characterized in terms of pH and particle size. For the safety assessment, alternative methods as cytotoxicity and HET CAM were used. The clinical skin compatibility tests were also performed. The efficacy was evaluated in healthy volunteers presenting different degrees of periorbital wrinkles. Skin hydration was performed by corneometry. The nanoparticles presented narrow size around 140 nm and pH close to neutral and were suitable to cutaneous application. The alternative tests demonstrated that the nanoparticles did not present potential to induce skin irritant effects, cytotoxicity or generate oxidative stress. The clinical assays confirmed the in vitro results, demonstrating the safety of the nanoparticles, which were not irritant, sensitizing and comedogenic. Furthermore, the exposure to UVA light did not cause photoxicity. Regarding the efficacy, nanoparticles presented significant reduction in wrinkle degree after 21 days of application compared to the control. The volunteers could differentiate the nanoparticles and the control product by means of subjective analyses. In conclusion, the nanoparticles containing antioxidant actives were safe for topical use and presented anti-aging activity in vivo and are suitable to be used as cosmetic ingredient.

Adoptive transfer of donor-derived T lymphocytes expressing a safety switch may promote immune reconstitution in patients undergoing haploidentical hematopoietic stem cell transplant (haplo-HSCT) without the risk for uncontrolled graft versus host disease (GvHD). Thus, patients who develop GvHD after infusion of allodepleted donor-derived T cells expressing an inducible human caspase 9 (iC9) had their disease effectively controlled by a single administration of a small-molecule drug (AP1903) that dimerizes and activates the iC9 transgene. We now report the long-term follow-up of 10 patients infused with such safety switch-modified T cells. We find long-term persistence of iC9-modified (iC9-T) T cells in vivo in the absence of emerging oligoclonality and a robust immunologic benefit, mediated initially by the infused cells themselves and subsequently by an apparently accelerated reconstitution of endogenous naive T lymphocytes. As a consequence, these patients have immediate and sustained protection from major pathogens, including cytomegalovirus, adenovirus, BK virus, and Epstein-Barr virus in the absence of acute or chronic GvHD, supporting the beneficial effects of this approach to immune reconstitution after haplo-HSCT.

Chronic pain in patients with advanced cancer poses a serious clinical challenge. The Δ9-tetrahydrocannabinol (THC)/cannabidiol (CBD) oromucosal spray (U.S. Adopted Name, nabiximols; Sativex(®)) is a novel cannabinoid formulation currently undergoing investigation as an adjuvant therapy for this treatment group. This follow-up study investigated the long-term safety and tolerability of THC/CBD spray and THC spray in relieving pain in patients with advanced cancer. In total, 43 patients with cancer-related pain experiencing inadequate analgesia despite chronic opioid dosing, who had participated in a previous three-arm (THC/CBD spray, THC spray, or placebo), two-week parent randomized controlled trial, entered this open-label, multicenter, follow-up study. Patients self-titrated THC/CBD spray (n=39) or THC spray (n=4) to symptom relief or maximum dose and were regularly reviewed for safety, tolerability, and evidence of clinical benefit. The efficacy end point of change from baseline in mean Brief Pain Inventory-Short Form scores for "pain severity" and "worst pain" domains showed a decrease (i.e., improvement) at each visit in the THC/CBD spray patients. Similarly, the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 scores showed a decrease (i.e., improvement) from baseline in the domains of insomnia, pain, and fatigue. No new safety concerns associated with the extended use of THC/CBD spray arose from this study. This study showed that the long-term use of THC/CBD spray was generally well tolerated, with no evidence of a loss of effect for the relief of cancer-related pain with long-term use. Furthermore, patients who kept using the study medication did not seek to increase their dose of this or other pain-relieving medication over time, suggesting that the adjuvant use of cannabinoids in cancer-related pain could provide useful benefit.

Treating hypercortisolism in patients with Cushing's disease after failed surgery often requires chronic medication, underlining the need for therapies with favourable long-term efficacy and safety profiles. In a randomised, double-blind study, 162 adult patients with persistent/recurrent or de novo Cushing's disease received pasireotide. Patients with mean urinary free cortisol at/below the upper limit of normal or clinical benefit at month 12 could continue receiving pasireotide during an open-ended, open-label phase, the outcomes of which are described herein. Sixteen patients received 5 years of pasireotide treatment. Among these, median (95% confidence interval) percentage change from baseline in mean urinary free cortisol was -82.6% (-89.0, -41.9) and -81.8% (-89.8, -67.4) at months 12 and 60. Eleven patients had mean urinary free cortisol ≤ upper limit of normal at month 60. Improvements in clinical signs were sustained during long-term treatment. The safety profile of pasireotide at 5 years was similar to that reported after 12 months. Fifteen of 16 patients experienced a hyperglycaemia-related adverse event; glycated haemoglobin levels were stable between months 6 and 60. Adverse events related to hyperglycaemia, bradycardia, gallbladder/biliary tract, and liver safety were most likely to first occur by month 6; adverse event severity did not tend to worsen over time. This represents the longest prospective trial of a medical therapy for Cushing's disease to date. A subset of patients treated with pasireotide maintained biochemical and clinical improvements for 5 years, with no new safety signals emerging. These data support the use of pasireotide as an effective long-term therapy for some patients with Cushing's disease.

Nuwiq ® (human-cl rhFVIII, simoctocog alfa) is a 4th generation recombinant human FVIII, without chemical modification or fusion with any other protein, produced in a human cell line. This study (GENA-13) was an extension of the GENA-03 study in which previously treated children aged 2-12 years with severe haemophilia A received Nuwiq ® prophylaxis for ≥6 months. GENA-13 examined long-term tolerability, immunogenicity and efficacy of Nuwiq ® prophylaxis in children. Of 59 patients enrolled in GENA-03, 49 continued Nuwiq ® prophylaxis in GENA-13 for a median (range) of 30.0 (9.5-52.0) months. No patient withdrew due to drug-related adverse events or developed inhibitors. Only 2 of 20 518 infusions were associated with possibly related adverse events (dyspnoea, fever). The estimated annualized bleeding rate (ABR) was 0.67 (95% CI: 0.44, 1.02) for spontaneous and 2.88 (95% CI: 1.86, 4.46) for all bleeds. Younger children (2-5 years) had lower ABRs than children aged 6-12 years. Annualized bleeding rates were reduced in GENA-13 vs GENA-03, especially for spontaneous bleeds in younger children (71% reduction; ABR ratio 0.29 [95% CI: 0.11, 0.74]). Nuwiq ® efficacy was rated as excellent/good in the treatment of 83.0% of 305 evaluated breakthrough bleeds. Surgical prophylaxis with Nuwiq ® was rated as excellent for all 17 assessed procedures. Long-term treatment with Nuwiq ® for the prevention of bleeds in children with severe haemophilia A was well tolerated, effective and reduced spontaneous bleeding by up to 70% compared with GENA-03. © 2018 The Authors.

Objective Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis. This post hoc analysis evaluated patients receiving tofacitinib monotherapy or combination therapy, as well as those who switched from monotherapy to combination therapy (mono→combo) or vice versa (combo→mono) in long-term extension (LTE) studies. Methods Data were pooled from open-label LTE studies (ORAL Sequel (NCT00413699; ongoing; data collected 14 January 2016) and NCT00661661) involving patients who participated in qualifying index studies. Efficacy outcomes included American College of Rheumatology 20/50/70 rates, change from baseline in Disease Activity Score in 28 joints, erythrocyte sedimentation rate (DAS28-4(ESR)), Clinical Disease Activity Index (CDAI) and Health Assessment Questionnaire-Disability Index and DAS28-4(ESR) and CDAI low disease activity and remission. Safety was evaluated over 96 months. Results Of the 4967 patients treated, 35.4% initiated tofacitinib monotherapy, 64.6% initiated combination therapy, 2.6% were mono→combo switchers and 7.1% were combo→mono switchers. Patients who switched multiple times were excluded. Of those who initiated monotherapy and combination therapy, 87.8% (1543/1757) and 82.0% (2631/3210), respectively, remained on the same regimen throughout the study; efficacy was maintained. Incidence rates (IRs) for serious adverse events with tofacitinib 5 mg and 10 mg twice daily, respectively, were 9.42 and 8.41 with monotherapy and 8.36 and 10.75 with combination therapy; IRs for discontinuations due to AEs were 7.13 and 6.06 with monotherapy and 7.82 and 8.06 with combination therapy (overlapping CIs). For mono→combo and combo→mono switchers, discontinuations due to AEs were experienced by 0.8% and 0.9%, respectively, within 30 days of switching. Conclusion Tofacitinib efficacy as monotherapy or combination therapy was maintained through month 48 and sustained to month 72, with minimal switching of treatment

Outcomes studies of the gastrointestinal safety of cyclooxygenase-2 inhibitors.

PubMed

Scheiman, James M

2002-01-01

Short-term endoscopic studies of the highly selective cyclooxygenase-2 (COX-2) inhibitors (coxibs) rofecoxib and celecoxib have shown that these agents are well tolerated and have efficacy equivalent to nonselective nonsteroidal anti-inflammatory drugs (NSAIDs) with fewer adverse effects on the upper gastrointestinal (GI) tract. These studies are limited, however, as the detection of endoscopic lesions is not well correlated with symptomatic ulcers and ulcer complications. Outcomes studies of the GI safety are, therefore, essential to understanding how coxibs are likely to perform in a clinical practice setting. Four large outcomes studies (Vioxx Gastrointestinal Outcomes Research, VIGOR; Assessment of Difference Between Vioxx and Naproxen to Ascertain Gastrointestinal Tolerability and Effectiveness trial, ADVANTAGE; Celecoxib Long-term Arthritis Safety Study, CLASS; and the Successive Celecoxib Efficacy and Safety Studies, SUCCESS) examined the GI safety of rofecoxib and celecoxib in over 39,000 patients with osteoarthritis or rheumatoid arthritis. Results of these studies showed that patients taking a supratherapeutic dose of rofecoxib or celecoxib had significantly lower rates of GI-related adverse events than those taking a nonselective NSAID (naproxen, ibuprofen, or diclofenac). Reduced risk of upper GI events was seen in patients with multiple risk factors and in patients using low-dose aspirin and corticosteroids concomitantly with a coxib. Results of large outcomes studies provide support for the COX-2 hypothesis and demonstrate the long-term safety and tolerability of coxibs.

Gene therapy has been investigated as a way to introduce a variety of genes to treat neurological disorders. An important clinical consideration is its long-term effectiveness. This research aims to study the long-term expression and effectiveness of gene therapy in promoting spiral ganglion neuron survival after deafness. Adenoviral vectors modified to express brain derived neurotrophic factor or neurotrophin-3 were unilaterally injected into the guinea pig cochlea one week post ototoxic deafening. After six months, persistence of gene expression and significantly greater neuronal survival in neurotrophin-treated cochleae compared to the contralateral cochleae were observed. The long-term gene expression observed indicates that gene therapy is potentially viable; however the degeneration of the transduced cells as a result of the original ototoxic insult may limit clinical effectiveness. With further research aimed at transducing stable cochlear cells, gene therapy may be an efficacious way to introduce neurotrophins to promote neuronal survival after hearing loss.

Improving the safety and security of civil infrastructure has become a critical issue for decades since it plays a central role in the economics and politics of a modern society. Structural health monitoring of civil infrastructure using wireless smart sensor network has emerged as a promising solution recently to increase structural reliability, enhance inspection quality, and reduce maintenance costs. Though hardware and software framework are well prepared for wireless smart sensors, the long-term real-time health monitoring strategy are still not available due to the lack of systematic interface. In this paper, the Imote2 smart sensor platform is employed, and a graphical user interface for the long-term real-time structural health monitoring has been developed based on Matlab for the Imote2 platform. This computer-aided engineering platform enables the control, visualization of measured data as well as safety alarm feature based on modal property fluctuation. A new decision making strategy to check the safety is also developed and integrated in this software. Laboratory validation of the computer aided engineering platform for the Imote2 on a truss bridge and a building structure has shown the potential of the interface for long-term real-time structural health monitoring.

Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). We evaluated the efficacy and safety of tofacitinib 5 or 10 mg twice daily (BID), in patients with moderate to severe RA, aged ≥65 and <65 years. Data were pooled from five Phase 3 trials and, separately, from two open-label long-term extension (LTE) studies (data cut-off April, 2012). Patients received tofacitinib, or placebo (Phase 3 only), with/without conventional synthetic DMARDs (mainly methotrexate). Clinical efficacy outcomes from Phase 3 studies were evaluated at Month 3. Safety evaluations using pooled Phase 3 data (Month 12) and pooled LTE data (Month 24) compared exposure-adjusted incidence rates (IRs; with 95% confidence intervals [CIs]), in older versus younger patients. In Phase 3 and LTE studies, 15.3% (475/3111) and 16.1% (661/4102) of patients, respectively, were aged ≥65 years. Consequently, exposure to tofacitinib was lower in older versus younger patients in Phase 3 (259.2 vs. 1554.9 patient years [pt-yrs]) and LTE (962.1 vs. 5071.7 pt-yrs) studies. Probability ratios for ACR responses and HAQ-DI improvement from baseline ≥0.22 (Month 3) favoured tofacitinib and were similar in older and younger patients, with overlapping CIs. IRs for SAEs and discontinuations due to AEs were generally numerically higher in older versus younger patients, irrespective of treatment. Older patients receiving tofacitinib 5 or 10 mg BID had a similar probability of ACR20 or ACR50 response and, due to comorbidities, a numerically higher risk of SAEs and discontinuations due to AEs compared with younger patients.

Development is defined sustainable when it meets the needs of the present without compromising the ability of future generations to meet their own needs. Pivoting on social, environmental and economic aspects of food chain sustainability, this paper presents the concept of sustainable food safety based on the prevention of risks and burden of poor health for generations to come. Under this respect, the assessment of long-term, transgenerational risks is still hampered by serious scientific uncertainties. Critical issues to the development of a sustainable food safety framework may include: endocrine disrupters as emerging contaminants that specifically target developing organisms; toxicological risks assessment in Countries at the turning point of development; translating knowledge into toxicity indexes to support risk management approaches, such as hazard analysis and critical control points (HACCP); the interplay between chemical hazards and social determinants. Efforts towards the comprehensive knowledge and management of key factors of sustainable food safety appear critical to the effectiveness of the overall sustainability policies.

This study assessed the long-term safety, tolerability, and maintenance of the therapeutic effect of brexpiprazole in Japanese patients with schizophrenia. This 52-week, open-label, flexible-dose (1-4 mg/day) study included patients with schizophrenia who continued treatment from a short-term randomized placebo-controlled fixed-dose (1, 2, or 4 mg/day) trial and de novo patients who switched from other antipsychotics. A total of 282 patients (184 de novo and 98 rolled over from short-term trial) entered the 52-week treatment with brexpiprazole, and 150 (53.2%) patients completed the week-52 assessment. Treatment-emergent adverse events (TEAE) were experienced by 235/281 patients (83.6%), and TEAE reported by ≥10% of all patients were nasopharyngitis (23.1%) and worsening of schizophrenia (22.4%). During the study, most of the TEAE were mild or moderate in severity, and there were no deaths, and no clinically meaningful mean changes in laboratory values, vital signs, or electrocardiogram parameters. Mean scores for the Positive and Negative Syndrome Scale total and Clinical Global Impression-Severity remained stable until week 52. Brexpiprazole was generally safe and well tolerated and maintained therapeutic effects in the long-term treatment of Japanese patients with schizophrenia. © 2018 The Authors.
