    Purpose Nivolumab, a programmed death-1 (PD-1) immune checkpoint inhibitor antibody, has demonstrated improved survival over docetaxel in previously treated advanced non–small-cell lung cancer (NSCLC). First-line monotherapy with nivolumab for advanced NSCLC was evaluated in the phase I, multicohort, Checkmate 012 trial. Methods Fifty-two patients received nivolumab 3 mg/kg intravenously every 2 weeks until progression or unacceptable toxicity; postprogression treatment was permitted per protocol. The primary objective was to assess safety; secondary objectives included objective response rate (ORR) and 24-week progression-free survival (PFS) rate; overall survival (OS) was an exploratory end point. Results Any-grade treatment-related adverse events (AEs) occurred in 71% of patients, most commonly: fatigue (29%), rash (19%), nausea (14%), diarrhea (12%), pruritus (12%), and arthralgia (10%). Ten patients (19%) reported grade 3 to 4 treatment-related AEs; grade 3 rash was the only grade 3 to 4 event occurring in more than one patient (n = 2; 4%). Six patients (12%) discontinued because of a treatment-related AE. The confirmed ORR was 23% (12 of 52), including four ongoing complete responses. Nine of 12 responses (75%) occurred by first tumor assessment (week 11); eight (67%) were ongoing (range, 5.3+ to 25.8+ months) at the time of data lock. ORR was 28% (nine of 32) in patients with any degree of tumor PD–ligand 1 expression and 14% (two of 14) in patients with no PD–ligand 1 expression. Median PFS was 3.6 months, and the 24-week PFS rate was 41% (95% CI, 27 to 54). Median OS was 19.4 months, and the 1-year and 18-month OS rates were 73% (95% CI, 59 to 83) and 57% (95% CI, 42 to 70), respectively. Conclusion First-line nivolumab monotherapy demonstrated a tolerable safety profile and durable responses in first-line advanced NSCLC. PMID:27354485

  3. Necessity of re-evaluation of estramustine phosphate sodium (EMP) as a treatment option for first-line monotherapy in advanced prostate cancer.

    2001-02-01

    Estramustine phosphate sodium (EMP) was first introduced in the early 1970s for the treatment of prostate cancer, when EMP was supposed to have the dual effect of estrogenic activity and cytotoxicity. For the following decades, it was used mainly in hormone-refractory cases, with a conventional dosage of 4-9 capsules/day, which showed a 30-35% objective response rate. However, a very limited number of cases have been reported that used EMP as a first-line monotherapy in the conventional dosage. One study showed a response rate of 82%, which is at least as effective as conventional estrogen (diethylstilbestrol; DES) monotherapy. Nevertheless, EMP was almost abandoned for the treatment of prostate cancer because of severe adverse side-effects, especially in the cardiovascular system and gastrointestinal tract. Recently, two facts have become evident. First, EMP interferes with cellular microtubule dynamics but does not show alkylating effects. Second, EMP is able to produce a complex with calcium when dairy products are taken concomitantly with EMP, resulting in a decrease in the absorption rate of EMP from the gut. Many clinical trials have been undertaken without warning against concomitant dairy product intake since the introduction of EMP. This fact will jeopardize almost all the clinical trials performed before 1990. It is considered that response rates have been underestimated and better results could have been obtained because side-effects decrease dose-dependently. Low-dose EMP monotherapy (2 capsules/day) has been performed infrequently in previously untreated advanced prostate cancer. The only large trial by the European Organization for Research and Treatment of Cancer in 1984 was biased in selecting patients. Nevertheless, the response rate of EMP is comparable to that of DES. In this study, the adverse side-effects of EMP were less than that of DES. Recently, a study was conducted at the University of Tokyo of 11 patients with advanced prostate cancer on

    Colorectal carcinomas (CRCs) are sensitive to treatment by anti-epidermal growth factor receptor (EGFR) antibodies only if they do not carry activating mutations in down-stream EGFR targets (KRAS/NRAS/BRAF). Most clinical trials for chemo-naive CRC patients involved combination of targeted agents and chemotherapy, while single-agent cetuximab or panitumumab studies included either heavily pretreated patients or subjects who were not selected on the basis of molecular tests. We hypothesized that anti-EGFR therapy would have significant efficacy in chemo-naive patients with KRAS/NRAS/BRAF mutation-negative CRC. Nineteen patients were prospectively included in the study. Two (11%) patients experienced partial response (PR) and 11 (58%) subjects showed stable disease (SD). Median time to progression approached 6.1 months (range 1.6-15.0 months). Cetuximab efficacy did not correlate with RNA expression of EGFR and insulin-like growth factor 2 (IGF2). Only one tumor carried PIK3CA mutation, and this CRC responded to cetuximab. Exome analysis of patients with progressive disease (PD) revealed 1 CRC with high-level microsatellite instability and 1 instance of HER2 oncogene amplification; 3 of 4 remaining patients with PD had allergic reactions to cetuximab, while none of the subjects with PR or SD had this complication. Comparison with 19 retrospective KRAS/NRAS/BRAF mutation-negative patients receiving first-line fluoropyrimidines revealed no advantages or disadvantages of cetuximab therapy. Cetuximab demonstrates only modest efficacy when given as a first-line monotherapy to KRAS/NRAS/BRAF mutation-negative CRC patients. It is of question, why meticulous patient selection, which was undertaken in the current study, did not result in the improvement of outcomes of single-agent cetuximab treatment.

    The combination of a fluoropyrimidine [5-fluorouracil (5-FU), capecitabine, or S-1] with a platinum analog (cisplatin or oxaliplatin) is the most widely accepted first-line chemotherapy regimen for metastatic or recurrent advanced gastric cancer (AGC), based on the results of clinical trials. However, there is little evidence to guide chemotherapy for elderly patients with AGC because of under-representation of this age group in clinical trials. Thus, the aim of this study is to determine the optimal chemotherapy regimen for elderly patients with AGC by comparing the efficacies and safeties of combination therapy versus monotherapy as first-line chemotherapy. This study is a randomized, controlled, multicenter, phase III trial. A total of 246 elderly patients (≥70 years old) with metastatic or recurrent AGC who have not received previous palliative chemotherapy will be randomly allocated to a combination therapy group or a monotherapy group. Patients randomized to the combination therapy group will receive fluoropyrimidine plus platinum combination chemotherapy (capecitabine/cisplatin, S-1/cisplatin, capecitabine/oxaliplatin, or 5-FU/oxaliplatin), and those randomized to the monotherapy group will receive fluoropyrimidine monotherapy (capecitabine, S-1, or 5-FU). The primary outcome is the overall survival of patients in each treatment group. The secondary outcomes include progression-free survival, response rate, quality of life, and safety. We are conducting this pragmatic trial to determine whether elderly patients with AGC will obtain the same benefit from chemotherapy as younger patients. We expect that this study will help guide decision-making for the optimal treatment of elderly patients with AGC.

    In patients with non-small-cell lung cancer (NSCLC), the effects of second-line chemotherapy on overall survival (OS) might be confounded by subsequent therapies. Therefore, using individual-level data, we aimed to determine the relationships between progression-free survival (PFS) and post-progression survival (PPS) with OS in patients with advanced NSCLC treated with docetaxel monotherapy as second-line chemotherapy. Between April 2002 and December 2014, data from 86 patients with advanced NSCLC who underwent second-line docetaxel monotherapy following first-line treatment with platinum combination chemotherapy were analyzed. The relationships of PFS and PPS with OS were analyzed at the individual level. Spearman rank correlation and linear regression analyses showed that PPS was strongly associated with OS (r = 0.86, p < 0.05, R2 = 0.93), whereas PFS was moderately correlated with OS (r = 0.50, p < 0.05, R2 = 0.21). Performance status at the end of second-line treatment and the number of regimens after progression beyond second-line chemotherapy were significantly associated with PPS (p < 0.05). In patients with advanced NSCLC with unknown oncogenic driver mutations undergoing docetaxel monotherapy as second-line chemotherapy, when compared with PFS, PPS had a stronger association with OS. This finding suggests that subsequent treatment after disease progression following second-line docetaxel monotherapy has a significant influence on OS. © 2017 S. Karger AG, Basel.

    We report a retrospective monocentric descriptive study performed in CHI Creteil for 20 months to describe the management and outcome of amikacin monotherapy as an alternative to third-generation cephalosporins for empiric treatment of febrile urinary tract infection (FUTI) in children. Data were analyzed for 151 children, and 90 selected cases were classified as certain or highly probable FUTI. Escherichia coli infection was found in 89 cases. In all patients, fever was resolved within 72 hours after beginning amikacin treatment. Only 5.3% of children were febrile after 48 hours. The mean amikacin treatment duration was 3.05 ± 0.13 days before oral treatment began (guided by antibiotic susceptibility testing). Amikacin monotherapy seems effective for the initial management of FUTI in children.

    BACKGROUND The approval of new immunotherapies has dramatically changed the treatment landscape of metastatic melanoma. These survival gains come with trade-offs in side effects and costs, as well as important considerations to third-party payer systems, physicians, and patients. OBJECTIVE Develop a Markov model to determine the cost-effectiveness of nivolumab, ipilimumab, and nivolumab-ipilimumab combination as first-line therapy in metastatic melanoma while accounting for differential effectiveness in PD-L1 positive and negative patients. METHODS A three-state Markov model (‘PD-L1 positive stable disease’, ‘PD-L1 negative stable disease’, and ‘Progression and/or Death’) was developed using a US societal perspective with a lifetime time horizon of 14.5 years. Transition probabilities were calculated from progression-free survival data reported in the CheckMate-067 trial. Costs were expressed in 2015 US dollars and were determined using national sources. Adverse event (AE) management was determined using immune-related AE (irAE) data from CheckMate-067, irAE management guides for nivolumab and ipilimumab, and treatment guidelines. Utilities were obtained from published literature, using melanoma-specific studies when available, and were weighted based on incidence and duration of irAEs. Base case, one-way sensitivity, and probabilistic sensitivity analyses were conducted. RESULTS Nivolumab-ipilimumab combination therapy is not the cost effective choice ($454,092 per progression-free quality-adjusted-life-year [PFQALY]) compared to nivolumab monotherapy in our base case analysis at a willingness-to-pay threshold of $100,000/PFQALY. Both combination therapy and nivolumab monotherapy were cost-effective choices compared to ipilimumab monotherapy. PD-L1 positive status, utility of nivolumab and combination therapy, and medication costs contributed the most uncertainty to the model. In a population of 100% PD-L1 negative patients, nivolumab was still the

    Evaluate real-life experience with eslicarbazepine acetate (ESL) after first monotherapy failure in a large series of patients with focal epilepsy. Multicentre, retrospective, 1-year, observational study in patients older than 18 years, with focal epilepsy, who had failed first antiepileptic drug monotherapy and who received ESL. Data from clinical records were analysed at baseline, 3, 6 and 12 months to assess effectiveness and tolerability. Eslicarbazepine acetate was initiated in 253 patients. The 1-year retention rate was 92.9%, and the final median dose of ESL was 800 mg. At 12 months, 62.3% of patients had been seizure free for 6 months; 37.3% had been seizure free for 1 year. During follow-up, 31.6% of the patients reported ESL-related adverse events (AEs), most commonly somnolence (8.7%) and dizziness (5.1%), and 3.6% discontinued due to AEs. Hyponatraemia was observed in seven patients (2.8%). After starting ESL, 137 patients (54.2%) withdrew the prior monotherapy and converted to ESL monotherapy; 75.9% were seizure free, 87.6% were responders, 4.4% worsened, and 23.4% reported ESL-related AEs. Use of ESL after first monotherapy failure was associated with an optimal seizure control and tolerability profile. Over half of patients were converted to ESL monotherapy during follow-up. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    After the discovery of activating mutations in EGFR, EGFR tyrosine kinase inhibitors (TKIs) have been introduced into the first-line treatment of non-small-cell lung cancer (NSCLC). A series of studies have shown that EGFR TKI monotherapy as first-line treatment can benefit NSCLC patients harbouring EGFR mutations. Besides, combination strategies based on EGFR TKIs in the first line treatment have also been proved to delay the occurrence of resistance. In this review, we summarize the scientific literature and evidence of EGFR TKIs as first-line therapy from the first-generation EGFR TKIs to conceptually proposed fourth-generation EGFR TKI, and also recommend the application of monotherapy and combination therapies of the EGFR-based targeted therapy with other agents such as chemotherapy, anti-angiogenic drugs and immunecheckpoint inhibitors.

    The effect of the dinucleotide P(1), P(4)-Di (adenosine-5') tetraphosphate (Ap4A) in improving adrenergic anti-glaucomatous delivery by modifying the tight junction proteins of the corneal epithelium was evaluated. Stratified human corneal epithelial cells (HCLE) were treated with Ap4A (100 μM) for 5 min and TJ protein levels and barrier function were analysed by western blotting and transepithelial electrical resistance (TEER), respectively. Western blot experiments showed a significant reduction at 2 h (45% reduction of ZO-1 and 65% reduction of occludin protein levels) as compared to non-treated (control) cells. Two hours after Ap4A treatment, TEER values were significantly reduced (65% as compared to control levels (p < 0.001)), indicating an increase in corneal barrier permeability. Topical application of Ap4A in New Zealand white rabbits two hours before the instillation of the hypotensor compounds (the α2-adrenergic receptor agonist, brimonidine and the β-adrenergic receptor antagonist, timolol), improved the delivery of these compounds to the anterior chamber as well as their hypotensive action on the intraocular pressure. The results obtained showed that, when Ap4A was topically applied two hours before the adrenergic compounds, the concentration of brimonidine in the aqueous humour increased from 64.3 ± 5.3 nM to 240.6 ± 8.6 nM and from 58.9 ± 9.2 nM to 183.7 ± 6.8 nM in the case of timolol, which also produces a more profound effect on IOP. Therefore, Ap4A treatment results in a better entrance of adrenergic anti-glaucomatous compounds within the eye and consequently improved therapeutic efficiency by increasing corneal epithelial barrier permeability.

    Insulin resistance is a prominent feature of polycystic ovary syndrome (PCOS), and insulin-sensitizing drugs are used to induce ovulation. Recently, it was reported that an extract from Maitake mushroom (Grifola frondosa) improves insulin resistance. The objective was to explore the effects of Maitake extract (SX-fraction: MSX) to induce ovulation in patients with PCOS in comparison with and in combination with clomiphene citrate (CC). We conducted an open trial with 80 patients with PCOS at three clinics in Japan. Seventy-two (72) new patients were randomly assigned to receive MSX or CC monotherapy for up to 12 weeks. Eighteen (18) patients who did not respond to MSX or CC were subjected to combination therapy of MSX and CC for up to 16 weeks. Eight (8) patients with documented history of failure to CC received combination therapy from the beginning. Ovulation was assessed by ultrasonography. Twenty-six (26) patients in the MSX group and 31 in the CC group were evaluated for ovulation. The ovulation rates for MSX and CC were as follows: 76.9% (20/26) and 93.5% (29/31), respectively by the patients (NS), and 41.7% (30/72) and 69.9% (58/83), respectively, by the cycles (p = 0.0006). In the combination therapy, 7 of 7 patients who failed in MSX monotherapy and 6 of 8 patients who failed in CC monotherapy showed ovulation. The present study suggests that MSX alone may induce ovulation in PCOS patients and may be useful as an adjunct therapy for patients who failed first-line CC treatment.

    A prospective multicenter observational study was undertaken on children and adults with epilepsy in whom first monotherapy failed, to assess indications and effects of alternative monotherapy vs. polytherapy. Patients were followed until 12-month remission, drug withdrawal, or up to 18months. Monotherapy and polytherapy were compared for patients' baseline features, indication, retention time, remission, adverse events (AE), quality of life, and direct and indirect costs. Included were 157 men and 174 women, aged 2-86years. Of the patients, 72.2% were switched to alternative monotherapy. Baseline treatment was changed for lack of efficacy (73.9%) or adverse events (26.1%). Two hundred forty-three completed the study (remission: 175; 72.0%). Retention time, hospital admissions, days off-work and off-school, and quality of life did not differ between the two treatment groups. Patients were followed for 365.3person-years. Three hundred eighty-three incident AEs were reported by 46.4% of patients in monotherapy and 40.2% in polytherapy (serious AEs: 9.6% vs. 8.7%, mostly nondrug-related). Copyright © 2013 Elsevier Inc.

    Follicular lymphoma (FL) is the most common type of non-Hodgkin lymphoma (NHL), with indolent progression. Several treatment options are selected, based not only on disease status, quality of life (QOL), and age of patient, but also on recent increasing medical costs. We retrospectively analysed the first-line treatment of FL with regard to treatment outcomes and medical economics, and discuss the appropriate strategies for FL. Data on a total of 69 newly-diagnosed patients with FL was retrospectively collected from 2001 to 2015. The median age of the patients was 60 years and the median follow-up was 58 months. A total of 25 cases with FL were treated with R monotherapy, and 28 cases were treated with R-CHOP as first-line treatment. The factors affecting the decision of physicians to use R or R-CHOP treatment were serum level of lactate dehydrogenase (LDH) and disease stage. The first-line treatment-associated survival did not show any statistical differences between R and R-CHOP. The average hospitalization and average of all medical costs during the first-line treatment were 4.1 days (R) versus 55.7 days (R-CHOP), and JPY 1,707,693 (USD 15,324) (R) versus JPY 2,136,117 (USD 19,170) (R-CHOP), respectively. R monotherapy for patients whose diseases show low tumor burden and who are not candidates for local treatment has benefits as a first-line treatment compared to R-CHOP, based on the patients' QOL and medical economics.

    Second-line chemotherapy has been proved to be effective on patients with relapsed or refractory small cell lung cancer (SCLC). Although topotecan has been approved by many countries for the monotherapy with an acknowledged efficacy, its efficacy of low response rate and short median survival time is disappointing. Considering the optimal regimen of second-line therapy is yet uncertain, we conducted this meta-analysis to provide theoretical basis for making clinical decisions. A comprehensive electronic search was performed to identify eligible studies. The ending points included response, overall survival (OS), and adverse events. Odds ratios and 95% confidence interval were calculated to compare the effects. Six trials with 1369 patients were included. With regard to response rate, only amrubicin showed a significant improvement compared with topotecan. Irinotecan and etoposide did not show any advantages. When targeted on OS, neither of these monotherapy regimens exhibited any advantage when compared to topotecan. When aimed at toxicity, amrubicin showed a better effect on reducing hematologic toxicity, but a worse outcome on increasing the nonhematologic toxicity, whereas others showed equal efficacy. There is no strong evidence that any advantage for second-line treatment of SCLC when compared with topotecan, except amrubicin. And amrubicin seems to be superior to topotecan in terms of response rates, with a lower toxicity than topotecan, which is of high value in clinical application, and may be the direction of second-line monotherapy in the future.

    The development of antiretroviral therapy (ART) with current triple drug combinations has dramatically reduced morbidity and mortality in HIV-infected patients. However, there is a need for less toxic treatments without sacrificing efficacy, as well as for less expensive drugs to facilitate universal access to this therapy. The protease inhibitors (PI) administered with ritonavir have a favorable pharmacokinetic profile and high genetic barrier and consequently are ideal candidates for use in monotherapy, thus avoiding the toxicity and cost associated with nucleoside analogs, as well as preserving drugs for future options. The promising results of studies performed with lopinavir/ritonavir (LPV/r) in induction-maintenance regimens in patients without prior failure to PIs encourage research into the cost-effectiveness of LPV/r in monotherapy from the beginning of ART. The few studies performed in this context seem to indicate the following: a) LPV/r monotherapy achieves undetectable viral loads in a large proportion of treatment-naïve patients, b) future treatment options are not compromised in patients not achieving undetectable viral loads since the likelihood of resistance mutations is low and treatment intensification achieves suppression of viral replication, and c) strategies for early detection can probably be considered in patients who will not achieve complete suppression with LPV/r monotherapy. Nevertheless, before LPV/r monotherapy can be considered a first-line option, new studies with larger samples and longer follow-up are required. These studies should pay particular attention to viral replication in areas where PI show less penetration.

    A multidisciplinary expert panel, the Italian board for the TAilored BIOlogic therapy (ITABIO), was constituted to formulate evidence-based decisional statements for the first-line tailored biologic therapy in patient with rheumatoid arthritis (RA), spondyloarthritis (SpA), and psoriatic arthritis (PsA). Systematic review of the literature to identify English-language articles on the variables influencing the first-line biologic choice, including the efficacy and safety of the drug, the route of administration, the availability of response predictor biomarkers, the need of monotherapy, the patient socio-economic status, lifestyle, cultural level, personality, fertility and childbearing potential in women, the presence of comorbidities, the host-related risk factors for infection and latent tuberculosis infection (LTBI) reactivation, the cardiovascular (CV) risk, and costs. Some variables, including the patients' preference, the indication for anti-TNF monotherapy in potential childbearing women, and the intravenous route with dose titration in obese subjects resulted valid for all the three rheumatic conditions. Further, evidence of a better cost-effectiveness profile for etanercept (ETN) and biosimilar infliximab (IFX) in RA was found. Any biologic may be employed in absence of choice driving factors in RA. Otherwise, a high infection risk or LTBI positivity drive the choice toward abatacept (ABA), tocilizumab (TCZ), or ETN. TCZ should be the first choice if monotherapy is required. High rheumatoid factor (RF) and anti-citrullinated protein antibodies (ACPA) titers should drive the choice toward TCZ or ABA, while in patients at high CVD risk anti-TNF choice, with preference for ETN, seems appropriate. Presence of anterior uveitis or inflammatory bowel disease drives the choice to monoclonal antibody anti-TNFs (MoAb anti-TNFs). In PsA, ustekinumab (UTK), and to a lesser extent ETN, represents the first choice in patients at high infection and TB risk. Anti-TNFs or

    2009-01-01

    Antiepileptic drug (AED) monotherapy is the preferred initial management approach in epilepsy care, since most patients may be successfully managed with the first or second monotherapy utilized. This article reviews the rationale and evidence supporting preferential use of monotherapy when possible and guidelines for initiating and successfully employing AED monotherapy. Suggested approaches to consider when patients fail monotherapy include substituting a new AED monotherapy, initiating chronic maintenance AED polytherapy, or pursuit of non-pharmacologic treatments such as epilepsy surgery or vagus nerve stimulation. Reducing AED polytherapy to monotherapy frequently reduces the burden of adverse effects and may also improve seizure control. AED monotherapy remains the optimal approach for managing most patients with epilepsy. PMID:19949565

    The antiglaucomatous effects of Glauplex 2 and pilocarpine nitrate on alpha-chymotrypsine-induced experimental glaucoma were studied in 8 rabbits. Changes in intraocular pressure were measured over a period of 12 hours after a single instillation of Glauplex 2 or two instillations of 2.6 p. cent pilocarpine nitrate at t = 0 and t = 6 hours. The antihypertensive effect of a single instillation of Glauplex 2 was shown to be approximately equivalent to that of two instillations of 2.6 p. cent pilocarpine nitrate.

    Intrahepatic cholangiocarcinoma is an aggressive tumor originating in the epithelium of the bile duct, often associated with distant dissemination. The prognosis is poor and treatment is challenging due to low response rate to standard chemotherapy and lack of targeted therapies. Here we report the case of a 74-year-old white woman affected by intrahepatic cholangiocarcinoma with metastatic involvement of spleen, lung, peritoneum, and intra-abdominal lymph nodes. As first-line chemotherapy, she was given cisplatin-gemcitabine chemotherapy. The treatment was well tolerated with the exception of grade 1 constipation and a single episode of grade 4 thrombocytopenia occurring after the fourth course. After the first three courses of chemotherapy a computed tomography scan evaluation demonstrated no change; her CA19-9 levels were slightly decreased. However, after the sixth course of chemotherapy a computed tomography scan revealed a dimensional enlargement of the lung metastases; her CA19-9 levels increased. She was then treated with gemcitabine alone. After 2 months of gemcitabine monotherapy a significant regression of lung and spleen metastases, as well a CA19-9 level reduction, occurred. Eight months after the start of gemcitabine monotherapy no signs of progression were reported. Treatment of metastatic intrahepatic cholangiocarcinoma with gemcitabine as maintenance therapy after first-line chemotherapy could be continued until clear evidence of disease progression since delayed responses are possible.

    The goal of epilepsy therapy is to help patients achieve seizure freedom without adverse effects. While monotherapy is preferable in epilepsy treatment, many patients fail a first drug due to lack of efficacy or failure to tolerate an initial medication, necessitating an alteration in therapy. Sudden changes between monotherapies are rarely feasible and sometimes deleterious given potential hazards of acute seizure exacerbation or intolerable adverse effects. The preferred method for converting between monotherapies is transitional polytherapy, a process involving initiation of a new antiepileptic drug (AED) and adjusting it toward a target dose while maintaining or reducing the dose of the baseline medication. A fixed-dose titration strategy of maintaining the baseline drug dose while titrating the new medication is preferable when breakthrough seizures are occurring and no adverse effects are present. However, a flexible titration strategy involving reduction of the baseline drug dose to ensure adequate tolerability of the new adjunctive medication is preferred when patients are already experiencing adverse effects. This article reviews pharmacokinetic considerations pertinent for ensuring successful transitional polytherapy with the standard and newer antiepileptic drugs. Practical consensus recommendations "from an expect panel (SPECTRA, Study by a Panel of Experts Considerations for Therapy Replacement and Antiepileptics) for a successful monotherapy" AED conversions are then summarized. Transitional polytherapy is most successful when clinicians appropriately manage the titration strategy and consider pharmacokinetic factors germane to the baseline and new adjunctive medication.

    Endocrine therapy is the cornerstone treatment for patients with hormone receptor-positive advanced breast cancer. We aimed to assess the effectiveness of various first-line endocrine monotherapies or combinations to determine the optimal sequence in a network meta-analysis. We searched PubMed, EMBASE, and the Cochrane Library for randomized controlled trials (RCTs) from inception up to November 21, 2017. We included only RCTs that assessed the effectiveness of the following treatments as a monotherapy or in combination as the first-line treatment: tamoxifen, anastrozole, letrozole, exemestane, fulvestrant, palbociclib, and ribociclib. The results were presented with pooled odds ratio or hazard ratio (HR), and 95% credible interval (CrI). The primary outcomes were objective response rate (ORR) and progression-free survival/time to progression. A total of 16 eligible articles (14 RCTs) involving 6,602 patients treated with 10 different first-line endocrine therapies were assessed in our network meta-analysis. Palbociclib plus letrozole was superior to anastrozole, letrozole, exemestane, fulvestrant 500 mg, and anastrozole plus fulvestrant (loading dose) (HR=0.44, 95% CrI: 0.33-0.58; HR=0.56, 95% CrI: 0.45-0.68; HR=0.45, 95% CrI: 0.32-0.61; HR=0.58, 95% CrI: 0.42-0.81; HR=0.50, 95% CrI: 0.37-0.68; respectively). However, there is no significant advantage compared with ribociclib plus letrozole (HR=1.00, 95% CrI: 0.72-1.39). In terms of ORR, ribociclib plus letrozole is more effective than palbociclib plus letrozole (odds ratio=1.30, 95% CrI: 0.83-2.02). Palbociclib plus letrozole and ribociclib plus letrozole might be the optimal first-line endocrine therapeutic choices for hormone receptor-positive/human epidermal growth factor receptor 2-negative advanced breast cancer due to a longer progression-free survival/time to progression and a more efficacious ORR.

    The approval of new immunotherapies has dramatically changed the treatment landscape of metastatic melanoma. These survival gains come with trade-offs in side effects and costs, as well as important considerations for third-party payer systems, physicians, and patients. To develop a Markov model to determine the cost-effectiveness of nivolumab, ipilimumab, and nivolumab-ipilimumab combination as firstline therapy in metastatic melanoma, while accounting for differential effectiveness in programmed death-ligand 1 (PD-L1) positive and negative patients. A 3-state Markov model (PD-L1 positive stable disease, PD-L1 negative stable disease, and progression and/or death) was developed using a U.S. societal perspective with a lifetime time horizon of 14.5 years. Transition probabilities were calculated from progression-free (PF) survival data reported in the CheckMate-067 trial. Costs were expressed in 2015 U.S. dollars and were determined using national sources. Adverse event (AE) management was determined using immune-related AE (irAE) data from CheckMate-067, irAE management guides for nivolumab and ipilimumab, and treatment guidelines. Utilities were obtained from published literature, using melanoma-specific studies when available, and were weighted based on incidence and duration of irAEs. Base case, one-way sensitivity, and probabilistic sensitivity analyses were conducted. Nivolumab-ipilimumab combination therapy was not the cost-effective choice ($454,092 per PF quality-adjusted life-year [QALY]) compared with nivolumab monotherapy in a base case analysis at a willingness-to-pay threshold of $100,000 per PFQALY. Combination therapy and nivolumab monotherapy were cost-effective choices compared with ipilimumab monotherapy. PD-L1 positive status, utility of nivolumab and combination therapy, and medication costs contributed the most uncertainty to the model. In a population of 100% PD-L1 negative patients, nivolumab was still the optimal treatment, but combination

    U.S. regulatory approvals of the cyclin-dependent kinase 4 and 6 (CDK 4/6) inhibitors ribociclib and palbociclib as add-ons to letrozole greatly enhance the prospects for treating postmenopausal women with hormone receptor-positive (HR+)/human epidermal receptor 2-negative (HER2-) advanced or metastatic breast cancer. Clinical trials have established that the combination of a CDK 4/6 inhibitor with letrozole can significantly improve progression-free survival (PFS) versus letrozole monotherapy and is safe and well tolerated. Cost-effectiveness studies are required to inform payers and clinical decision makers on the money value of combination treatment in clinical practice. To evaluate the cost-effectiveness of ribociclib plus letrozole versus palbociclib plus letrozole and versus letrozole monotherapy in the first-line treatment of postmenopausal women with HR+/HER2- advanced or metastatic breast cancer from a U.S. private third-party payer perspective. A partitioned survival model including 3 health states (progression free, with either overall response or stable disease; progressed disease; and death) simulated lifetime costs and outcomes over a 40-year lifetime horizon with a 1-month cycle length. Clinical efficacy data (PFS and overall survival [OS]) were derived from a phase III trial of ribociclib plus letrozole (MONALEESA-2; NCT01958021), a phase II trial of palbociclib plus letrozole (PALOMA-1; NCT00721409), and a Bayesian network meta-analysis. Health care costs included drug acquisition and monitoring, disease management, subsequent therapies, and serious drug-related adverse events. Effectiveness was measured in life-years, derived from survival projections, and in quality-adjusted life-years (QALYs), calculated from time spent in each state combined with health-state utility values. A one-way deterministic sensitivity analysis explored the impact of uncertainty in key model parameters on results, and probabilistic uncertainty was assessed through a

    In order to guide the antimalarial treatment policy of Somalia, we conducted therapeutic efficacy studies of routinely used antimalarial monotherapies as well as artemisinin-based combination therapies (ACTs) for uncomplicated malaria in three sentinel sites during 2003-2006. Therapeutic efficacy of chloroquine (CQ), amodiaquine (AQ) and sulfadoxine/pyrimetahmine (SP) monotherapies, and artesunate plus SP (AS+SP) or AQ (AS+AQ) were evaluated in children 6 months to 10 years old with uncomplicated malaria. For the assessment of the monotherapies, 2003 WHO protocol with 14-day follow-up was used while the 2005 WHO protocol with 28-day follow-up was used for testing the ACTs. Of the monotherapies, CQ performed very poorly with treatment failures varying from 76.5% to 88% between the sites. AQ treatment failure was low except for Janale site with treatment failure of 23.4% compared to 2.8% and 8% in Jamame and Jowhar, respectively. For SP, treatment failures from 7.8% to 12.2% were observed. A 28-day test of artemisinin-based combinations, AS+SP and AS+AQ, proved to be highly efficacious with cure rates of 98-100% supporting the choice of AS+SP combination as first line treatment for uncomplicated malaria for Somalia.

    Despite satisfactory efficacy of WHO-recommended second-line antiretroviral treatment for patients with HIV in low-income countries, the need for simplified, low-cost, and less-toxic maintenance strategies remains high. We compared boosted protease inhibitor monotherapy with dual therapy with boosted protease inhibitor plus lamivudine in patients on second-line antiretrovial therapy (ART). We did a multicentre, randomised, parallel, open-label, superiority, trial in the HIV services of five hospitals in sub-Saharan Africa (Yaoundé, Cameroon; Dakar, Senegal; and Bobo Dioulasso, Burkina Faso). We recruited patients from the long-term, post-trial cohort of the ANRS 12169/2LADY study that compared the efficacy of three second-line combinations based on boosted protease inhibitors. Participants for our study were HIV-1 infected with multiple mutations including M184V, at first-line failure, aged 18 years and older, on boosted protease inhibitor plus two nucleoside reverse transcriptase inhibitors (NRTI) for at least 48 weeks with at least 48 weeks follow-up in the 2LADY trial, with two viral load measurements of less than 200 copies per mL in the previous 6 months, CD4 counts of more than 100 cells per μL, adherence of at least 90%, and no change to ART in the past 3 months. We randomly assigned participants (1:1) to receive either monotherapy with their boosted protease inhibitor (once-daily darunavir 800 mg [two 400 mg tablets] boosted with ritonavir 100 mg [one tablet] or coformulation of lopinavir 200 mg with ritonavir 50 mg [two tablets taken twice per day]) or to boosted protease inhibitor plus once-daily lamivudine 300 mg (one 300 mg tablet or two 150 mg tablets). Computer-generated randomisation was stratified by study site and viral load at screening (< 50 copies per mL, and 50-200 copies per mL), and concealed from study personnel throughout the inclusion period.

    To assess neurocognitive function at the first-line antiretroviral therapy failure and change on the second-line therapy. Randomized controlled trial was conducted in 5 sub-Saharan African countries. Patients failing the first-line therapy according to WHO criteria after >12 months on non-nucleoside reverse transcriptase inhibitors-based regimens were randomized to the second-line therapy (open-label) with lopinavir/ritonavir (400 mg/100 mg twice daily) plus either 2-3 clinician-selected nucleoside reverse transcriptase inhibitors, raltegravir, or as monotherapy after 12-week induction with raltegravir. Neurocognitive function was tested at baseline, weeks 48 and 96 using color trails tests 1 and 2, and the Grooved Pegboard test. Test results were converted to an average of the 3 individual test z-scores. A total of 1036 patients (90% of those >18 years enrolled at 13 evaluable sites) had valid baseline tests (58% women, median: 38 years, viral load: 65,000 copies per milliliter, CD4 count: 73 cells per cubic millimeter). Mean (SD) baseline z-score was -2.96 (1.74); lower baseline z-scores were independently associated with older age, lower body weight, higher viral load, lower hemoglobin, less education, fewer weekly working hours, previous central nervous system disease, and taking fluconazole (P < 0.05 in multivariable model). Z-score was increased by mean (SE) of +1.23 (0.04) after 96 weeks on the second-line therapy (P < 0.001; n = 915 evaluable), with no evidence of difference between the treatment arms (P = 0.35). Patients in sub-Saharan Africa failing the first-line therapy had low neurocognitive function test scores, but performance improved on the second-line therapy. Regimens with more central nervous system-penetrating drugs did not enhance neurocognitive recovery indicating this need not be a primary consideration in choosing a second-line regimen.

    Two cases with partial onset epilepsy who developed status epilepticus (SE) on lacosamide (LCM) monotherapy are reported. LCM is an effective adjunctive antiepileptic drug (AED) for partial-onset epilepsy and as infusion in SE. It has also shown efficacy in monotherapy. The reported cases achieved control of seizures with adjunctive LCM treatment and were afterwards converted to monotherapy. Both patients subsequently developed SE while on LCM monotherapy. They were on monotherapy for at least 2 months after withdrawal of concomitant AEDs precluding the possibility of withdrawal-induced SE. Pharmacovigilance is indicated when LCM is administered in monotherapy in order to assess its proper therapeutic potential and its putative limitations especially in cases where it may prove ineffective. Moreover, vigilance is necessary whenever any concomitant antiepileptic is tapered regardless of the substances used. Higher doses may be needed when an AED is used in monotherapy. PMID:25628098

    Genentech and ImmunoGen are collaborating on the development of trastuzumab emtansine, a HER2 antibody-drug conjugate that comprises Genentech's trastuzumab antibody linked to ImmunoGen's anti-mitotic agent, mertansine (a maytansine derivative; also known as DM1). The conjugate combines two strategies: the anti-HER2 activity of trastuzumab, and the targeted intracellular delivery of mertansine, a tubulin polymerisation inhibitor which interferes with mitosis and promotes apoptosis. The linker in trastuzumab emtansine is a non-reducible thioether linker, N-succinimidyl-4-(N-maleimidomethyl) cyclohexane-1-carboxylate (SMCC, designated MCC after conjugation). Trastuzumab emtansine (Kadcyla™) has been launched in the USA as second-line monotherapy for HER2-positive metastatic breast cancer, and has been filed for approval in the EU and Japan in this indication. Trastuzumab emtansine is in phase III development as first-line combination therapy or monotherapy for metastatic HER2-positive breast cancer, and as third-line monotherapy for metastatic HER2-positive breast cancer. Phase II development is underway for early-stage breast cancer and phase II/III development is underway in patients with HER2-positive gastric cancer. This article summarizes the milestones in the development of trastuzumab emtansine leading to this first approval for the treatment of patients with HER2-positive, metastatic breast cancer who previously received trastuzumab and a taxane, separately or in combination.

    Ovarian cancer remains one of the most lethal of all gynecologic malignancies, accounting for more deaths than cervical and uterine cancer combined. Advanced ovarian cancer is a chemosensitive tumor and most patients initially respond to platinum-based combination chemotherapy with response rates of about 70%, including a high proportion of complete responses. However, despite aggressive surgery and chemotherapy, more than 80% of patients will relapse and will then be treated with second line chemotherapy with objective responses in about 20% of patients and even lower percentages of complete responses. We observed a 42-months of complete response with administration of 1-[2-tetrahydrofuryl]-5-fluorouracil mixed with uracil (UFT) in patient with platinium refractory ovarian cancer. We report a complete remission of platinium refractory epithelial ovarian cancer with UFT monotherapy that was not reported previously.

    To evaluate the effects of the activation of endogenous angiotensin-converting enzyme 2 (ACE2) using the compound diminazene aceturate (DIZE) in an experimental model of glaucoma in Wistar rats. DIZE (1 mg/kg) was administered daily, either systemically or topically, and the IOP was measured weekly. To examine the role of the Mas receptor in the effects of DIZE, the Ang-(1-7) antagonist A-779 was co-administered. Drainage of the aqueous humor was evaluated by using scintigraphy. The analysis of ACE2 expression by immunohistochemistry and the counting of retinal ganglion cells (RGCs) were performed in histologic sections. Additionally, the nerve fiber structure was evaluated by transmission electron microscopy. The systemic administration and topical administration (in the form of eye drops) of DIZE increased the ACE2 expression in the eyes and significantly decreased the IOP of glaucomatous rats without changing the blood pressure. Importantly, this IOP-lowering action of DIZE was similar to the effects of dorzolamide. The antiglaucomatous effects of DIZE were blocked by A-779. Histologic analysis revealed that the reduction in the number of RGCs and the increase in the expression of caspase-3 in the RGC layer in glaucomatous animals were prevented by DIZE. This compound also prevented alterations in the cytoplasm of axons in glaucomatous rats. In addition to these neuroprotective effects, DIZE facilitated the drainage of the aqueous humor. Our results evidence the pathophysiologic relevance of the ocular ACE2/Ang-(1-7)/Mas axis of the renin-angiotensin system and, importantly, indicate that the activation of intrinsic ACE2 is a potential therapeutic strategy to treat glaucoma.

    The efficacy of second or third-line chemotherapy in advanced non-small cell lung cancer (NSCLC) patients is low. The use of targeted drugs brings survival benefit for some patients. Apatinib, as a novel small molecule antiangiogenic drug, has demonstrated satisfactory anticancer activity across a broad range of malignancies. The aim of this study is to evaluate the efficacy and safety of apatinib in patients with advanced NSCLC after first-line treatment failure. A retrospective study of 128 patients was conducted to evaluate the safety, short-term efficacy and survival status with different regimens. Kaplan-Meier method and Cox regression model were used for analysis. Compared with chemotherapy alone, the median progression free survival (PFS) in apatinib monotherapy, chemotherapy alone and apatinib combined with chemotherapy were 3.0 (P=0.381), 3.7 and 6.0 months (P<0.001), respectively. The median overall survival (OS) were 6.0 (P=0.494), 6.5 and 9.0 months (P=0.001), respectively. The incidence of adverse events in grades 3-4 were 18.5%, 15.8% and 16.0%, respectively (P=0.947). Different treatment regimens (P=0.018) and performance status (PS)(P<0.001) were the independent factors of PFS. The smoking history (P=0.014), treatment regimens (P=0.002) and PS (P<0.001) were independent influencing factors of OS. Apatinib has a good security. After first-line treatment failure of lung cancer, chemotherapy combined with apatinib in second or third-line is beneficial in PFS and OS when compared with chemotherapy alone. But when making comparison between apatinib monotherapy and chemotherapy alone, there is no significant difference in PFS and OS. Patients who never smoke or has a better PS or use combination therapy have longer survival time.

    Several clinical trials have proven that icotinib hydrochloride, a novel epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor, exhibits encouraging efficacy and tolerability in patients with advanced non-small-cell lung cancer (NSCLC) who failed previous chemotherapy. This study was performed to assess the efficacy and toxicity of icotinib as first-line therapy for patients with advanced pulmonary adenocarcinoma with EGFR-sensitive mutation. Thirty-five patients with advanced NSCLC with EGFR-sensitive mutation who were sequentially admitted to the First Affiliated Hospital of Xi'an Jiaotong University from March 2012 to March 2014 were enrolled into our retrospective research. All patients were administered icotinib as first-line treatment. The tumor responses were evaluated using Response Evaluation Criteria in Solid Tumors (RECIST, version 1.1). Among the 35 patients, the tumor objective response rate (ORR) and disease control rate were 62.9% (22/35) and 88.6% (31/35), respectively. The median progression-free survival was 11.0 months (95% confidence interval [CI]: 10.2-11.8 months), and median overall survival was 21.0 months (95% CI: 20.1-21.9 months). The most common drug-related toxicities were rashes (eleven patients) and diarrhea (nine patients), but these were generally manageable and reversible. Icotinib monotherapy is effective and tolerable as first-line treatment for patients with advanced lung adenocarcinoma with EGFR-sensitive mutation.

    To assess the efficacy and safety of the anti-VEGF receptor-2 (VEGFR-2) antibody ramucirumab as first-line therapy in patients with advanced hepatocellular carcinoma and explore potential circulating biomarkers. Adults with advanced hepatocellular carcinoma and no prior systemic treatment received ramucirumab 8 mg/kg every two weeks until disease progression or limiting toxicity. The primary endpoint was progression-free survival (PFS); secondary endpoints included objective response rate (ORR) and overall survival (OS). Circulating biomarkers were evaluated before and after ramucirumab treatment in a subset of patients. Forty-two patients received ramucirumab. Median PFS was 4.0 months [95% confidence interval (CI), 2.6-5.7], ORR was 9.5% (95% CI, 2.7-22.6; 4/42 patients had a partial response), and median OS was 12.0 months (95% CI, 6.1-19.7). For patients with Barcelona Clinic Liver Cancer (BCLC) stage C disease, median OS was 4.4 months (95% CI, 0.5-9.0) for patients with Child-Pugh B cirrhosis versus 18.0 months (95% CI, 6.1-23.5) for patients with Child-Pugh A cirrhosis. Treatment-related grade ≥ 3 toxicities included hypertension (14%), gastrointestinal hemorrhage and infusion-related reactions (7% each), and fatigue (5%). There was one treatment-related death (gastrointestinal hemorrhage). After treatment with ramucirumab, there was an increase in serum VEGF and placental growth factor (PlGF) and a transient decrease in soluble VEGFR-2. Ramucirumab monotherapy may confer anticancer activity in advanced hepatocellular carcinoma with an acceptable safety profile. Exploratory biomarker studies showed changes in circulating VEGF, PlGF, and sVEGFR-2 that are consistent with those seen with other anti-VEGF agents. ©2013 AACR.

    Millions of HIV-infected people worldwide receive antiretroviral therapy (ART) in programmes using WHO-recommended standardised regimens. Recent WHO guidelines recommend a boosted protease inhibitor plus raltegravir as an alternative second-line combination. We assessed whether this treatment option offers any advantage over the standard protease inhibitor plus two nucleoside reverse-transcriptase inhibitors (NRTIs) second-line combination after 144 weeks of follow-up in typical programme settings. We analysed the 144-week outcomes at the completion of the EARNEST trial, a randomised controlled trial done in HIV-infected adults or adolescents in 14 sites in five sub-Saharan African countries (Uganda, Zimbabwe, Malawi, Kenya, Zambia). Participants were those who were no longer responding to non-NRTI-based first-line ART, as assessed with WHO criteria, confirmed by viral-load testing. Participants were randomly assigned to receive a ritonavir-boosted protease inhibitor (lopinavir 400 mg with ritonavir 100 mg, twice per day) plus two or three clinician-selected NRTIs (protease inhibitor plus NRTI group), protease inhibitor plus raltegravir (400 mg twice per day; protease inhibitor plus raltegravir group), or protease inhibitor monotherapy (plus raltegravir induction for first 12 weeks, re-intensified to combination therapy after week 96; protease inhibitor monotherapy group). Randomisation was by computer-generated randomisation sequence, with variable block size. The primary outcome was viral load of less than 400 copies per mL at week 144, for which we assessed non-inferiority with a one-sided α of 0·025, and superiority with a two-sided α of 0·025. The EARNEST trial is registered with ISRCTN, number 37737787. Between April 12, 2010, and April 29, 2011, 1837 patients were screened for eligibility, of whom 1277 patients were randomly assigned to an intervention group. In the primary (complete-case) analysis at 144 weeks, 317 (86%) of 367 in the protease inhibitor

    Objectives Erlotinib, the first generation of epidermoid growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI), has been recommended as an essential treatment in patients with non-small-cell lung cancer (NSCLC) with EGFR mutation. Although it has improved progression-free survival (PFS), overall survival (OS) was limited and erlotinib can be expensive. This cost-effectiveness analysis compares erlotinib monotherapy with gemcitabine-included doublet chemotherapy. Setting First-line treatment of Asian patients with NSCLC with EGFR mutation. Methods A Markov model was created based on the results of the ENSURE (NCT01342965) and OPTIMAL (CTONG-0802) trials which evaluated erlotinib and chemotherapy. The model simulates cancer progression and all causes of death. All medical costs were calculated from the perspective of the Chinese healthcare system. Main outcome measures The primary outcomes are costs, quality-adjusted life years (QALYs) and incremental cost-effectiveness ratios (ICERs). Results The combined PFS was 11.81 months and 5.1 months for erlotinib and chemotherapy, respectively, while the OS was reversed at 24.68 months for erlotinib and 26.16 months for chemotherapy. The chemotherapy arm gained 0.13 QALYs compared with erlotinib monotherapy (1.17 QALYs vs 1.04 QALYs), while erlotinib had lower costs ($55 230 vs $77 669), resulting in an ICER of $174 808 per QALY for the chemotherapy arm, which exceeds three times the Chinese GDP per capita. The most influential factors were the health utility of PFS, the cost of erlotinib and the health utility of progressed disease. Conclusion Erlotinib monotherapy may be acceptable as a cost-effective first-line treatment for NSCLC compared with gemcitabine-based chemotherapy. The results were robust to changes in assumptions.

    Background. The development of drug resistance to nucleoside reverse transcriptase inhibitors (NRTIs) and nonnucleoside reverse transcriptase inhibitors (NNRTIs) has been associated with baseline human immunodeficiency virus (HIV)-1 RNA level (VL), CD4 cell counts (CD4), subtype, and treatment failure duration. This study describes drug resistance and levels of susceptibility after first-line virologic failure in individuals from Thailand, South Africa, India, Malawi, Tanzania. Methods. CD4 and VL were captured at AIDs Clinical Trial Group (ACTG) A5230 study entry, a study of lopinavir/ritonavir (LPV/r) monotherapy after first-line virologic failure on an NNRTI regimen. HIV drug-resistance mutation associations with subtype, site, study entry VL, and CD4 were evaluated using Fisher exact and Kruskall–Wallis tests. Results. Of the 207 individuals who were screened for A5230, sequence data were available for 148 individuals. Subtypes observed: subtype C (n = 97, 66%) AE (n = 27, 18%), A1 (n = 12, 8%), and D (n = 10, 7%). Of the 148 individuals, 93% (n = 138) and 96% (n = 142) had at least 1 reverse transcriptase (RT) mutation associated with NRTI and NNRTI resistance, respectively. The number of NRTI mutations was significantly associated with a higher study screening VL and lower study screening CD4 (P < .001). Differences in drug-resistance patterns in both NRTI and NNRTI were observed by site. Conclusions. The degree of NNRTI and NRTI resistance after first-line virologic failure was associated with higher VL at study entry. Thirty-two percent of individuals remained fully susceptible to etravirine and rilpivirine, protease inhibitor resistance was rare. Some level of susceptibility to NRTI remained; however, VL monitoring and earlier virologic failure detection may result in lower NRTI resistance. PMID:24795328

    To evaluate the 1-year efficacy and safety of oral lacosamide as conversion monotherapy in adult patients with partial onset seizures with or without generalization. We prospectively followed-up consecutive patients converted to lacosamide monotherapy after 1-year seizure freedom on lacosamide add-on therapy and withdrawal of the concurrent antiepileptic drug (AED). Seizure occurrence, treatment compliance and drug toxicity were assessed every 3 months up to 1 year. The study outcomes were the retention rate of lacosamide as single AED and the seizure freedom under lacosamide monotherapy at 1 year from withdrawal of background AED. The safety variable was the prevalence of lacosamide related adverse events (AEs). Among the 58 included patients, at 1 year from withdrawal of background medication, 37 (63.8%) retained lacosamide as single AED and 32 (55.2%) were free from seizure occurrence under lacosamide monotherapy throughout the entire follow-up. The history of less than three lifetime AEDs turned out to be significant predictor of seizure freedom (adjusted OR = 6.38, 95% CI 1.85-21.98, p = 0.003). Twelve (20.8%) subjects reported mild to moderate AEs, with the commonest being drowsiness, dizziness, and headache. Conversion to lacosamide monotherapy could be effective and well tolerated in selected adults patients with partial onset seizures who had achieved seizure freedom during lacosamide add-on therapy.

    Objective To evaluate and compare long-term effectiveness of five antiepileptic drugs (AEDs) for monotherapy of adult patients with focal epilepsy in routine clinical practice. Methods Adult patients with focal epilepsy, who were prescribed with carbamazepine (CBZ), valproate (VPA), lamotrigine (LTG), topiramate (TPM), or oxcarbazepine (OXC) as monotherapy, during the period from January 2004 to June 2012 registered in Wenzhou Epilepsy Follow Up Registry Database (WEFURD), were included in the study. Prospective long-term follow-up was conducted until June 2013. The endpoints were time to treatment failure, time to seizure remission, and time to first seizure. Results This study included 654 patients: CBZ (n=125), VPA (n=151), LTG (n=135), TPM (n=76), and OXC (n=167). The retention rates of CBZ, VPA, LTG, TPM, and OXC at the third year were 36.1%, 32.4%, 57.6%, 37.9%, and 41.8%, respectively. For time to treatment failure, LTG was significantly better than CBZ and VPA (LTG vs. CBZ, hazard ratio, [HR] 0.80 [95% confidence interval: 0.67-0.96], LTG vs. VPA, 0.53 [0.37-0.74]); TPM was worse than LTG (TPM vs. LTG, 1.77 [1.15-2.74]), and OXC was better than VPA (0.86 [0.78-0.96]). After initial target doses, the seizure remission rates of CBZ, VPA, LTG, TPM, and OXC were 63.0%, 77.0%, 83.6%, 67.9%, and 75.3%, respectively. LTG was significantly better than CBZ (1.44 [1.15-1.82]) and OXC (LTG vs. OXC, 0.76 [0.63-0.93]); OXC was less effective than LTG in preventing the first seizure (1.20 [1.02-1.40]). Conclusion LTG was the best, OXC was better than VPA only, while VPA was the worst. The others were equivalent for comparisons between five AEDs regarding the long-term treatment outcomes of monotherapy for adult patients with focal epilepsy in a clinical practice. For selecting AEDs for these patients among the first-line drugs, LTG is an appropriate first choice; others are reservation in the first-line but VPA is not. PMID:26147937

    Objective: To assess pregabalin monotherapy for partial-onset seizures using a historical-controlled conversion-to-monotherapy design. Methods: Adults with inadequately controlled partial-onset seizures while receiving 1 or 2 antiepileptic drugs during an 8-week prospective baseline were randomized to double-blind monotherapy with pregabalin 600 or 150 mg/d (4:1) for 20 weeks (8-week conversion and 12-week monotherapy period). The primary endpoint was the seizure-related exit rate for pregabalin 600 mg/d, based on discontinuations due to predefined criteria. Efficacy was declared if the upper limit of the 95% confidence interval for the exit rate was below a historical-control threshold of 74%, with stepwise evaluation using a threshold of 68%. Results: The trial was stopped early for positive efficacy after an interim analysis in 125 patients. The full study population included 161 patients, with 148 evaluable for efficacy. The mean time since epilepsy diagnosis was 14 years. Overall, 54.3% (600 mg/d) and 46.9% (150 mg/d) of patients completed 20 weeks of double-blind treatment. Seizure-related exit rate in the 600 mg/d group (27.5%; 95% confidence interval, 17.8%–37.2%) was significantly below the 74% and 68% thresholds (p < 0.001 for both). Eight patients on 600 mg/d and 2 on 150 mg/d were seizure-free throughout pregabalin monotherapy. Pregabalin's overall safety profile was consistent with prior trials. Conclusions: Pregabalin monotherapy was safe and efficacious for patients with inadequately controlled partial-onset seizures. Classification of evidence: This study provides Class III evidence that patients with inadequately controlled partial-onset seizures switched to pregabalin monotherapy have fewer seizure-related exit events compared with historical controls switched to pseudo-placebo monotherapy.

    Evidence of reduced cardiovascular morbidity and mortality as well as cost support thiazide diuretics as the first-line choice for treatment of hypertension. The purpose of this study was to determine the proportion of senior hypertensives that received thiazide diuretics as first-line treatment, and to determine if cardiovascular and other potentially relevant comorbidities predict the choice of first-line therapy. British Columbia PharmaCare data were used to determine the cohort of seniors (residents aged 65 or older) who received their first reimbursed hypertension drug during the period 1993 to 2000. These individual records were linked to medical and hospital claims data using the British Columbia Linked Health Database to find the subset that had diagnoses indicating the presence of hypertension as well as cardiovascular and other relevant comorbidities. Rates of first-line thiazide prescribing as proportion of all first-line treatment were analysed, accounting for patient age, sex, overall clinical complexity, and potentially relevant comorbidities. For the period 1993 to 2000, 82,824 seniors who had diagnoses of hypertension were identified as new users of hypertension drugs. The overall rate at which thiazides were used as first-line treatment varied from 38% among senior hypertensives without any potentially relevant comorbidity to 9% among hypertensives with previous acute myocardial infarction. The rate of first-line thiazide diuretic prescribing for patients with and without potentially relevant comorbidities increased over the study period. Women were more likely than men, and older patients were more likely than younger, to receive first-line thiazide therapy. Findings indicate that first-line prescribing practices for hypertension are not consistent with the evidence from randomized control trials measuring morbidity and mortality. The health and financial cost of not selecting the most effective and least costly therapeutic options are significant.

    A randomized, parallel-group, open-label, multicenter 16-week clinical trial compared efficacy and safety of repaglinide monotherapy and nateglinide monotherapy in type 2 diabetic patients previously treated with diet and exercise. Enrolled patients (n = 150) had received treatment with diet and exercise in the previous 3 months with HbA(1c) >7 and < or =12%. Patients were randomized to receive monotherapy with repaglinide (n = 76) (0.5 mg/meal, maximum dose 4 mg/meal) or nateglinide (n = 74) (60 mg/meal, maximum dose 120 mg/meal) for 16 weeks. Primary and secondary efficacy end points were changes in HbA(1c) and fasting plasma glucose (FPG) values from baseline, respectively. Postprandial glucose, insulin, and glucagon were assessed after a liquid test meal (baseline, week 16). Safety was assessed by incidence of adverse events or hypoglycemia. Mean baseline HbA(1c) values were similar in both groups (8.9%). Final HbA(1c) values were lower for repaglinide monotherapy than nateglinide monotherapy (7.3 vs. 7.9%). Mean final reductions of HbA(1c) were significantly greater for repaglinide monotherapy than nateglinide monotherapy (-1.57 vs. -1.04%; P = 0.002). Mean changes in FPG also demonstrated significantly greater efficacy for repaglinide than nateglinide (-57 vs. -18 mg/dl; P < 0.001). HbA(1c) values <7% were achieved by 54% of repaglinide-treated patients versus 42% for nateglinide. Median final doses were 6.0 mg/day for repaglinide and 360 mg/day for nateglinide. There were 7% of subjects treated with repaglinide (five subjects with one episode each) who had minor hypoglycemic episodes (blood glucose <50 mg/dl) versus 0 patients for nateglinide. Mean weight gain at the end of the study was 1.8 kg in the repaglinide group as compared with 0.7 kg for the nateglinide group. In patients previously treated with diet and exercise, repaglinide and nateglinide had similar postprandial glycemic effects, but repaglinide monotherapy was significantly more effective than

    To assess the cost-effectiveness of first-line pemetrexed/platinum and other commonly administered regimens in a representative US elderly population with advanced non-squamous non-small cell lung cancer (NSCLC). This study utilized the Surveillance Epidemiology and End Results (SEER) cancer registry linked to Medicare claims records. The study population included all SEER-Medicare patients diagnosed in 2008-2009 with advanced non-squamous NSCLC (stages IIIB-IV) as their only primary cancer and who started chemotherapy within 90 days of diagnosis. The study evaluated the four most commonly observed first-line regimens: paclitaxel/carboplatin, platinum monotherapy, pemetrexed/platinum, and paclitaxel/carboplatin/bevacizumab. Overall survival and total healthcare cost comparisons as well as incremental cost-effectiveness ratios (ICERs) were calculated for pemetrexed/platinum vs each of the other three. Unstratified analyses and analyses stratified by initial disease stage were conducted. The final study population consisted of 2,461 patients. Greater administrative censorship of pemetrexed recipients at the end of the study period disproportionately reduced the observed mean survival for pemetrexed/platinum recipients. The disease stage-stratified ICER analysis found that the pemetrexed/platinum incurred total Medicare costs of $536,424 and $283,560 per observed additional year of life relative to platinum monotherapy and paclitaxel/carboplatin, respectively. The pemetrexed/platinum vs triplet comparator analysis indicated that pemetrexed/platinum was associated with considerably lower total Medicare costs, with no appreciable survival difference. Limitations included differential censorship of the study regimen recipients and differential administration of radiotherapy. Pemetrexed/platinum yielded either improved survival at increased cost or similar survival at reduced cost relative to comparator regimens in the treatment of advanced non-squamous NSCLC.

    Antiepileptic drugs (AEDs) are the only neurotherapeutics for which regulatory approval is consistently separated into monotherapy or adjunctive-therapy indications. Because head-to-head comparisons of AEDs (used in the European Union to approve drugs for monotherapy) have not shown substantial differences in efficacy between drugs, FDA approval for use of an AED as monotherapy has typically been based on trials with novel designs that have been criticised for reasons of ethics and clinical relevance. Many new-generation AEDs have not been approved for monotherapy, causing drug labelling and real-world use to be increasingly inconsistent, with negative consequences for patients. The regulatory requirement for separate monotherapy and adjunctive-therapy indications in epilepsy is unnecessarily restrictive. We recommend that regulatory agencies approve AEDs for the treatment of specific seizure types or epilepsy syndromes, irrespective of concomitant drug use. Copyright © 2015 Elsevier Ltd.

    The empirical administration of a broad-spectrum beta-lactam antibiotic, either as monotherapy or in combination with an aminoglycoside, is an essential component of the initial management of patients with fever and severe neutropenia. Multiple antibiotics have been tested for this indication. Cefepime is a fourth-generation cephalosporin with in vitro activity against most gram-negative and many gram-positive bacteria. We have studied the use of this agent as monotherapy in this indication. One hundred and twenty-six episodes of febrile neutropenia in 98 adults with hematological malignancies were treated with cefepime monotherapy. Cefepime was given at a dose of 2 g every 8 h i.v. Most episodes (49%) were fever of unexplained origin, while a microbiologically documented and clinically documented infection occurred in 25% episodes each. Seventy-six (61%) episodes occurred after conventional chemotherapy, while 51 (41%) after a hematopoietic stem cell transplantation. Twelve episodes (10%) were not evaluable for response. Among the 114 evaluable episodes, 69 (55% of the initial sample and 61% of those evaluable) responded to cefepime monotherapy, while therapy failed in 45 cases (36% of the initial sample and 39% of those evaluable), including 14 cases who developed breakthrough bacteremia during therapy. There were no deaths due to bacterial infection. At the end of all antibiotic therapy (final outcome) 69 episodes were cured only with monotherapy, 47 were cured with modification of therapy and 10 patients died from an unrelated cause. The only variable that appeared to correlate with response to therapy was the duration of neutropenia, which was longer among patients who failed or developed breakthrough bacteremia than among those who responded to monotherapy. Initial empirical antibiotic therapy with cefepime as a single agent in patients with febrile neutropenia and a hematological malignancy is effective, but patients with prolonged neutropenia appear to be

Methods: This post hoc pooled analysis of 2 randomized double-blind studies (093-045 and -046) included adults with partial-onset seizures medically uncontrolled by 1 or 2 antiepileptic drugs (AEDs). Following the baseline period (8 weeks), eligible patients were randomized 2:1 to receive ESL 1,600 mg or 1,200 mg once daily for 18 weeks; the primary endpoint was study exit by meeting predefined exit criteria (signifying worsening seizure control). In each study, treatment was considered effective if the upper 95% confidence limit for exit rate was lower than the historical control threshold (65.3%). Results: Pooled exit rates were as follows: ESL 1,600 mg = 20.6% (95% confidence interval: 15.6%–26.8%); ESL 1,200 mg = 30.8% (23.0%–40.5%). Use of 2 baseline AEDs or rescue medication, US location, epilepsy duration ≥20 years, and higher maximum baseline seizure frequency were associated with higher exit risks. Median percent reductions in standardized seizure frequency between baseline and the 18-week double-blind period were as follows: ESL 1,600 mg = 43.2%; ESL 1,200 mg = 35.7%; baseline carbamazepine use was associated with smaller reductions. Safety profiles were similar between ESL doses. Conclusions: Exit rates for ESL monotherapy (1,600 mg and 1,200 mg once daily) were lower than the historical control threshold, irrespective of baseline AED use and region, with no additional safety concerns identified. Clinical factors and location clearly influence treatment responses in conversion-to-monotherapy trials. Classification of evidence: This pooled analysis provides Class IV evidence that for adults with medically uncontrolled partial-onset seizures, ESL monotherapy is well tolerated and effective.

    Cannabidiol (CBD), one of the major products of the marijuana plant, is devoid of marijuana's typical psychological effects. In contrast, potential antipsychotic efficacy has been suggested based on preclinical and clinical data (Zuardi et al., 2002). In this report, we further investigated the efficacy and safety of CBD monotherapy in three patients with treatment-resistant schizophrenia (TRS). This was an in-patient study. All patients were given placebo for the initial 5 days, and from the 6th to 35th day (inclusive) they received CBD (initial oral dose of 40 mg reaching 1280 mg/day). On the 36th day, CBD treatment was discontinued and replaced by placebo for 5 days, which was subsequently switched to olanzapine for over 15 days. Efficacy, tolerability and side effects were assessed. One patient showed mild improvement, but two patients didn't show any improvement during CBD monotherapy. All patients tolerated CBD very well and no side effects were reported. These preliminary data suggest that CBD monotherapy may not be effective for TRS.

    The efficacy and toxic effects of nucleoside reverse-transcriptase inhibitors (NRTIs) are uncertain when these agents are used with a protease inhibitor in second-line therapy for human immunodeficiency virus (HIV) infection in resource-limited settings. Removing the NRTIs or replacing them with raltegravir may provide a benefit. In this open-label trial in sub-Saharan Africa, we randomly assigned 1277 adults and adolescents with HIV infection and first-line treatment failure to receive a ritonavir-boosted protease inhibitor (lopinavir-ritonavir) plus clinician-selected NRTIs (NRTI group, 426 patients), a protease inhibitor plus raltegravir in a superiority comparison (raltegravir group, 433 patients), or protease-inhibitor monotherapy after 12 weeks of induction therapy with raltegravir in a noninferiority comparison (monotherapy group, 418 patients). The primary composite end point, good HIV disease control, was defined as survival with no new World Health Organization stage 4 events, a CD4+ count of more than 250 cells per cubic millimeter, and a viral load of less than 10,000 copies per milliliter or 10,000 copies or more with no protease resistance mutations at week 96 and was analyzed with the use of imputation of data (≤4%). Good HIV disease control was achieved in 60% of the patients (mean, 255 patients) in the NRTI group, 64% of the patients (mean, 277) in the raltegravir group (P=0.21 for the comparison with the NRTI group; superiority of raltegravir not shown), and 55% of the patients (mean, 232) in the monotherapy group (noninferiority of monotherapy not shown, based on a 10-percentage-point margin). There was no significant difference in rates of grade 3 or 4 adverse events among the three groups (P=0.82). The viral load was less than 400 copies per milliliter in 86% of patients in the NRTI group, 86% in the raltegravir group (P=0.97), and 61% in the monotherapy group (P<0.001). When given with a protease inhibitor in second-line therapy, NRTIs

    Antibiotic streamlining is pivotal to reduce the emergence of resistant bacteria. However, whether streamlining is frequently performed and safe in difficult situations, such as bacteremic pneumococcal pneumonia (BPP), has still to be assessed. All adult patients admitted to Dijon Hospital (France) from 2005 to 2013 who had BPP without complications, and were alive on the third day were enrolled. Clinical, biological, radiological, microbiological and therapeutic data were recorded. A first analysis was conducted to assess factors associated with being on amoxicillin on the third day. A second analysis, adjusting for a propensity score, was performed to determine whether 30-day mortality was associated with streamlining to amoxicillin monotherapy. Of the 196 patients hospitalized for BPP, 161 were still alive on the third day and were included in the study. Treatment was streamlined to amoxicillin in 60 patients (37%). Factors associated with not streamlining were severe pneumonia (OR 3.11, 95%CI [1.23-7.87]) and a first-line antibiotic combination (OR 3.08, 95%CI [1.34-7.09]). By contrast, starting with amoxicillin monotherapy correlated inversely with the risk of subsequent treatment with antibiotics other than amoxicillin (OR 0.06, 95%CI [0.01-0.30]). The Cox model adjusted for the propensity-score analysis showed that streamlining to amoxicillin during BPP was not significantly associated with a higher risk of 30-day mortality (HR 0.38, 95%CI [0.08-1.87]). Streamlining to amoxicillin is insufficiently implemented during BPP. This strategy is safe and potentially associated with ecological and economic benefits; therefore, it should be further encouraged, particularly when antibiotic combinations are started for severe pneumonia.

    Extensive molecular heterogeneity of pancreatic ductal adenocarcinoma (PDA), few effective therapies and high mortality make this disease a prime model for advancing development of tailored therapies. The p16-cyclin D-cyclin-dependent kinase 4/6-retinoblastoma (RB) protein (CDK4) pathway, regulator of cell proliferation, is deregulated in PDA. Our aim was to develop a novel personalised treatment strategy for PDA based on targeting CDK4. Sensitivity to potent CDK4/6 inhibitor PD-0332991 (palbociclib) was correlated to protein and genomic data in 19 primary patient-derived PDA lines to identify biomarkers of response. In vivo efficacy of PD-0332991 and combination therapies was determined in subcutaneous, intrasplenic and orthotopic tumour models derived from genome-sequenced patient specimens and genetically engineered model. Mechanistically, monotherapy and combination therapy were investigated in the context of tumour cell and extracellular matrix (ECM) signalling. Prognostic relevance of companion biomarker, RB protein, was evaluated and validated in independent PDA patient cohorts (>500 specimens). Subtype-specific in vivo efficacy of PD-0332991-based therapy was for the first time observed at multiple stages of PDA progression: primary tumour growth, recurrence (second-line therapy) and metastatic setting and may potentially be guided by a simple biomarker (RB protein). PD-0332991 significantly disrupted surrounding ECM organisation, leading to increased quiescence, apoptosis, improved chemosensitivity, decreased invasion, metastatic spread and PDA progression in vivo. RB protein is prevalent in primary operable and metastatic PDA and may present a promising predictive biomarker to guide this therapeutic approach. This study demonstrates the promise of CDK4 inhibition in PDA over standard therapy when applied in a molecular subtype-specific context. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Epilepsy is a common neurological condition with a worldwide prevalence of around 1%. Approximately 60% to 70% of people with epilepsy will achieve a longer-term remission from seizures, and most achieve that remission shortly after starting antiepileptic drug treatment. Most people with epilepsy are treated with a single antiepileptic drug (monotherapy) and current guidelines from the National Institute for Health and Care Excellence (NICE) in the United Kingdom for adults and children recommend carbamazepine or lamotrigine as first-line treatment for partial onset seizures and sodium valproate for generalised onset seizures; however a range of other antiepileptic drug (AED) treatments are available, and evidence is needed regarding their comparative effectiveness in order to inform treatment choices. To compare the time to withdrawal of allocated treatment, remission and first seizure of 10 AEDs (carbamazepine, phenytoin, sodium valproate, phenobarbitone, oxcarbazepine, lamotrigine, gabapentin, topiramate, levetiracetam, zonisamide) currently used as monotherapy in children and adults with partial onset seizures (simple partial, complex partial or secondary generalised) or generalised tonic-clonic seizures with or without other generalised seizure types (absence, myoclonus). We searched the following databases: Cochrane Epilepsy's Specialised Register, CENTRAL, MEDLINE and SCOPUS, and two clinical trials registers. We handsearched relevant journals and contacted pharmaceutical companies, original trial investigators, and experts in the field. The date of the most recent search was 27 July 2016. We included randomised controlled trials of a monotherapy design in adults or children with partial onset seizures or generalised onset tonic-clonic seizures (with or without other generalised seizure types). This was an individual participant data (IPD) review and network meta-analysis. Our primary outcome was 'time to withdrawal of allocated treatment', and our secondary

    The aim of this case study was to acquire understanding concerning the first-line nurse manager's goal-profile, i.e. prioritization of goals in her work as a first-line nurse manager, through use of an action-theoretic and confirmatory theory. The first-line nurse manager's pivotal role regarding quality of care and development in relation to on-going changes in the health care sector is stressed by many researchers and the transition from nurse to manager is described as a demanding challenge for the first-line nurse manager. The case study described in this paper concerns a first-line nurse manager in an actual working environment in care of older people. Data collection comprised interviews, observations, a job description and policy documents. A hermeneutic interpretation was used for data analysis. The results showed that the first-line nurse manager had three goals in her goal-profile, in the following order of priority: (i) a nurse goal that she had strongly accepted and in which she had excellent control, (ii) an administrator goal that she had accepted and in which she had control, (iii) a leadership goal that she had not accepted and in which she did not have control. Both the administrator and leadership goals were based on her job description, but the nurse goal was a personally chosen goal based on her own self-relation/goal-fulfillment. The first-line nurse manager's prioritized self-identity, based on successful realization of goals in her goal-profile, was decisive in the manifestation of her work. This study contributes to a new understanding of the first-line nurse manager's self-identity related to work in terms of goal acceptance and goal control of prioritized goals. This action-theoretic approach could be a valuable 'key' for understanding leadership (or lack of leadership) in clinical practice.

    Renin-angiotensin system (RAS) inhibitors are widely prescribed for treatment of hypertension, especially for diabetic patients on the basis of postulated advantages for the reduction of diabetic nephropathy and cardiovascular morbidity and mortality. Despite widespread use of angiotensin converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) for hypertension in both diabetic and non-diabetic patients, the efficacy and safety of RAS inhibitors compared to other antihypertensive drug classes remains unclear. To evaluate the benefits and harms of first-line RAS inhibitors compared to other first-line antihypertensive drugs in patients with hypertension. We searched the Cochrane Hypertension Group's Specialised Register, MEDLINE, MEDLINE In-Process, EMBASE and ClinicalTrials.gov for randomized controlled trials up to November 19, 2014 and the Cochrane Central Register of Controlled Trials (CENTRAL) up to October 19, 2014. The WHO International Clinical Trials Registry Platform (ICTRP) is searched for inclusion in the Cochrane Hypertension Group's Specialised Register. We included randomized, active-controlled, double-blinded studies with at least six months follow-up in people with primary elevated blood pressure (≥130/85 mmHg), which compared first-line RAS inhibitors with other first-line antihypertensive drug classes and reported morbidity and mortality or blood pressure outcomes. Patients with proven secondary hypertension were excluded. Two authors independently selected the included trials, evaluated the risk of bias and entered the data for analysis. We included 42 studies, involving 65,733 participants, with a mean age of 66 years. Much of the evidence for our key outcomes is dominated by a small number of large studies at a low risk of bias for most sources of bias. Imbalances in the added second-line antihypertensive drugs in some of the studies were important enough for us to downgrade the quality of the evidence.Primary outcomes were

    This is the first update of a review published in 2009. Sustained moderate to severe elevations in resting blood pressure leads to a critically important clinical question: What class of drug to use first-line? This review attempted to answer that question. To quantify the mortality and morbidity effects from different first-line antihypertensive drug classes: thiazides (low-dose and high-dose), beta-blockers, calcium channel blockers, ACE inhibitors, angiotensin II receptor blockers (ARB), and alpha-blockers, compared to placebo or no treatment.Secondary objectives: when different antihypertensive drug classes are used as the first-line drug, to quantify the blood pressure lowering effect and the rate of withdrawal due to adverse drug effects, compared to placebo or no treatment. The Cochrane Hypertension Information Specialist searched the following databases for randomized controlled trials up to November 2017: the Cochrane Hypertension Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (from 1946), Embase (from 1974), the World Health Organization International Clinical Trials Registry Platform, and ClinicalTrials.gov. We contacted authors of relevant papers regarding further published and unpublished work. Randomized trials (RCT) of at least one year duration, comparing one of six major drug classes with a placebo or no treatment, in adult patients with blood pressure over 140/90 mmHg at baseline. The majority (over 70%) of the patients in the treatment group were taking the drug class of interest after one year. We included trials with both hypertensive and normotensive patients in this review if the majority (over 70%) of patients had elevated blood pressure, or the trial separately reported outcome data on patients with elevated blood pressure. The outcomes assessed were mortality, stroke, coronary heart disease (CHD), total cardiovascular events (CVS), decrease in systolic and diastolic blood pressure, and

    We recently reported on a randomized, open-label, phase 3 trial comparing pemetrexed-cisplatin chemotherapy followed by gefitinib maintenance therapy (PC/G) with gefitinib monotherapy in patients with non-small cell lung cancer (NSCLC). Here, we report on a post hoc subgroup analysis of that study assessing the demographics and disposition of the Korean patient subgroup, and comparing the tolerability of PC/G and gefitinib monotherapy and the tumor response with respect to epidermal growth factor receptor (EGFR) status. Patients, who were ≥ 18 years, chemonaïve, Korean, light ex-smokers/never-smokers with advanced NSCLC, were randomly assigned (1:1) to PC/G or gefitinib monotherapy. Treatment-emergent adverse events (TEAEs) were graded, and tumor response was measured as change in lesion sum from baseline at best response. The study was registered with ClinicalTrials. gov, NCT01017874. Overall, 111 Korean patients were treated (PC/G, 51; gefitinib, 60). Between-arm characteristics were balanced and similar to those of the overall population. Treatment discontinuations due to adverse events were low (PC/G: 1, 2.0%; gefitinib: 7, 11.7%). Overall, 92 patients (82.9%) reported ≥ 1 TEAE (PC/G, 44; gefitinib, 48); few patients (PC/G, 16; gefitinib, 7) reported severe TEAEs; the most frequent was neutropenia (PC/G arm) and elevated alanine aminotransferase (gefitinib arm). The lesion sum was decreased by PC/G treatment in most patients, regardless of EGFR mutation status, while gefitinib monotherapy reduced the lesion sum in EGFR-positive patients but had no effect in EGFR-negative patients. Our results confirm that both PC/G and gefitinib were well tolerated in Korean patients, regardless of EGFR status; however, patients with EGFR wild-type NSCLC may not benefit from gefitinib monotherapy.

    The relative use of brachytherapy (BT) for prostate cancer has declined in recent years. In this setting, we sought to determine whether the case mix of BT monotherapy-treated men has changed over time in terms of risk group composition. The Surveillance, Epidemiology, and End Results database was used to identify 30,939 patients diagnosed with prostate adenocarcinoma between 2004 and 2011 who received BT monotherapy. The case mix of BT monotherapy patients was calculated by patient risk group and year of diagnosis. Between 2004 and 2011, the use of BT monotherapy declined overall. The relative percentage of men undergoing BT with low-risk disease declined by 4.5%, whereas the relative percentage of patients with intermediate-risk disease increased by 4.7%. Non-white patients and those from poorer counties did not show shifts in the risk group makeup of BT monotherapy patients, whereas white patients and those from wealthier counties did. Although fewer patients with prostate cancer are undergoing BT monotherapy, men with intermediate-risk disease comprised a significantly larger portion of the BT case mix in 2011 compared with 2004. Future research efforts by brachytherapists should be directed toward improving BT technique, optimizing radiation doses, and obtaining long-term followup data for patients with intermediate-risk prostate cancer.

    This is an updated version of the original Cochrane review published in Issue 2, 2002 and its subsequent update in 2010.Epilepsy is a common neurological condition in which recurrent, unprovoked seizures are caused by abnormal electrical discharges from the brain. It is believed that with effective drug treatment, up to 70% of individuals with active epilepsy have the potential to become seizure-free and go into long-term remission shortly after starting drug therapy with a single antiepileptic drug in monotherapy.Worldwide, carbamazepine and phenytoin are commonly used broad spectrum antiepileptic drugs, suitable for most epileptic seizure types. Carbamazepine is a current first line treatment for partial onset seizures in the USA and Europe. Phenytoin is no longer considered a first line treatment due to concerns over adverse events associated with its use, however the drug is still commonly used in low- to middle-income countries due to it's low cost. No consistent differences in efficacy have been found between carbamazepine and phenytoin in individual trials, however the confidence intervals generated by these studies are wide. Therefore, differences in efficacy may be shown by synthesising the data of the individual trials. To review the time to withdrawal, six- and 12-month remission, and first seizure of carbamazepine compared to phenytoin when used as monotherapy in people with partial onset seizures (simple partial, complex partial, or secondarily generalised tonic-clonic seizures) or generalised tonic-clonic seizures, with or without other generalised seizure types.

    Background Biologics are a safe and efficacious therapy for psoriasis. The drug survival of biologics may be disappointing, primarily due to loss of efficacy. Therefore, safe combination treatments are sought to improve their clinical response. Objective To assess the efficacy, safety and tolerability of the combination therapy of etanercept with fumarates versus etanercept monotherapy. Methods Thirty-three patients with psoriasis were randomized 1:1 to receive etanercept combined with fumarates or etanercept monotherapy. The primary outcome measure was the difference in PASI-75 response after 24 weeks; additionally, a longitudinal analysis was performed. An important secondary outcome measure was the proportion of patients with a Physician Global Assessment (PGA) of clear or almost clear. Adverse events were collected throughout the study. Results In the combination therapy group, 78% (14 out of 18 patients) reached PASI-75 at week 24 versus 57% (8 out of 14 patients) in the monotherapy group (p = 0.27). The longitudinal analysis showed a PASI reduction of 5.97% per week for the combination therapy group and of 4.76% for the monotherapy group (p = 0.11). In the combination therapy group, 94% (17 out of 18 patients) of patients had a PGA of clear/almost clear versus 64% (9 out of 14 patients) in the monotherapy group (p = 0.064). The incidence of mild gastrointestinal complaints was higher in the combination group than in the monotherapy group. Conclusion Using the PGA, combination therapy showed a trend towards faster improvement in the first 24 weeks. The difference in the PASI score between the two groups was not statistically significant. Addition of fumarates to etanercept for 48 weeks appeared safe with an acceptable tolerability.

    Studies of the effect of oxcarbazepine (OXC) on body growth of children with epilepsy are rare and their results are controversial. To the contrary, many studies have shown significant weight gain following valproate (VPA) treatment. To prospectively evaluate the effect of OXC monotherapy on growth patterns of children with epilepsy and compare it with the effect of VPA monotherapy. Fifty-nine otherwise healthy children, aged 3.7-15.9 years, with primary generalized, partial or partial with secondary generalization seizure disorder, were included in the study. Twenty six children were placed on OXC and thirty three on VPA monotherapy. Body weight (BW), height and body mass index (BMI) as well as their standard deviation scores (SDS), were evaluated prior to as well as 8 months post initiation of OXC or VPA therapy. Eight months post OXC-treatment, BW, SDS-BW, BMI and SDS-BMI increased significantly. The increase was similar to that observed in the VPA group. An additional 15.4% of children in the OXC group and 21.2% in the VPA group became overweight or obese. The effect of both OXC and VPA therapy on linear growth did not reach statistical significance. Similarly to VPA, OXC monotherapy resulted in a significant weight gain in children with epilepsy. Careful monitoring for excess weight gain along with counseling on adapting a healthy lifestyle should be offered to children on OXC therapy. Copyright © 2016 Elsevier B.V. All rights reserved.

    Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) are now key agents in treating EGFR-mutant non-small cell lung cancer (NSCLC). The efficacy of gefitinib or erlotinib monotherapy can be predicted by the development of a skin rash. However, it has not been fully evaluated if this is the case with afatinib monotherapy. We retrospectively studied 49 consecutive patients with EGFR-mutant NSCLC who received afatinib therapy between 2009 and 2015. The relationship of several toxicities with tumor response was examined. Grade 2, or more severe, common adverse events (AEs) included skin rash in 17 patients (35 %), diarrhea in 19 (39 %) and mucositis in 15 (31 %). Of these, the number of patients who developed ≥Grade 2 AEs during the first week after the initiation of afatinib therapy was: five patients had skin rash (10 %), 12 patients had diarrhea (25 %) and four patients had mucositis (8 %). As for an objective response, 21 (43 %) of the 49 had a partial response. Associating the AEs with the antitumor effect, those who had a ≥Grade 2 skin rash within the first week tended to have a greater tumor response compared with those without a rash (80 vs. 39 %; p = 0.077). Our small study demonstrated that the early development of a skin rash might be associated with the response to afatinib monotherapy.

    Darunavir/ritonavir monotherapy maintains HIV suppression in most patients who have achieved an undetectable viral load on combination antiretroviral treatment, and is increasingly used in the clinic. However, concerns have been raised about the effectiveness of ritonavir-boosted protease inhibitor (PI/r) monotherapy in the prevention of HIV replication in the central nervous system (CNS). Here we report the cases of 2 patients on darunavir/r maintenance monotherapy with cerebrospinal fluid viral breakthrough together with increased immunoactivation and biomarker signs of neuronal injury. These 2 cases raise concerns about the effectiveness of darunavir/ritonavir monotherapy in HIV CNS infection. Thus, we recommend caution with protease inhibitor monotherapy until CNS results have been obtained from clinical studies. PMID:22776013

    Background First-line levofloxacin-based treatments eradicate Helicobacter pylori with varying success. We examined the efficacy and safety of first-line levofloxacin-based treatment in comparison to standard first-line therapy for H pylori eradication. Materials and Methods We searched literature databases from Medline, EMBASE, and the Cochrane Register of Randomized Controlled Trials through March 2013 for randomized controlled trials comparing first-line levofloxacin and standard therapy. We included randomized controlled trials conducted only on naïve H pylori infected patients in adults. A systematic review was conducted. Meta-analysis was performed with Review Manager 5.2. Treatment effect was determined by relative risk with a random or fixed model by the Mantel-Haenszel method. Results Seven trials were identified with 888 patients receiving 7 days of first-line levofloxacin and 894 treated with standard therapy (Amoxicillin, Clarithromycin and proton pump inhibitor) for 7 days. The overall crude eradication rate in the Levofloxacin group was 79.05% versus 81.4% in the standard group (risk ratio 0.97; 95% CI; 0.93, 1.02). The overall dropout was 46 (5.2%) in the levofloxacin group and 52 (5.8%) for standard therapy. The dizziness was more common among group who took Levofloxacin based treatment and taste disturbance was more common among group who took standard therapy. Meta-analysis of overall adverse events were similar between the two groups with a relative risk of 1.06 (95% CI 0.72, 1.57). Conclusion Helicobacter pylori eradication with 7 days of Levofloxacin-based first line therapy was safe and equal compared to 7 days of standard first-line therapy. PMID:24465624

    A case of erythema multiforme associated with gemfibrozil monotherapy. A 46-year-old man with hyperlipidemia was treated with 600 mg gemfibrozil twice a day. On the fifth day of treatment, skin lesions consistent with erythema multiforme appeared. With the discontinuation of the treatment and start of a topical steroid treatment, the lesions recovered after 4 weeks. After 6 months, when gemfibrozil therapy was restarted, lesions reappeared on the fourth day of therapy. Lesions recovered again following the previous treatment strategies after 4 weeks. An objective casualty assessment suggests that erythema multiforme was probably related to gemfibrozil monotherapy. Patients starting gemfibrozil therapy should be warned about the occurrence of erythema multiforme in addition to previous reported and established side effects.

    The aim of this study was to evaluate the impact of two different therapeutic strategies in patients with partial seizures who were intractable to the first prescribed antiepileptic drug (AED); alternative monotherapy vs early add-on treatment. We conducted an open, cluster-randomised, prospective, controlled trial in patients with persistent partial seizures, despite treatment with one AED, who were never administered any other AEDs. Neurologists were randomised to two strategies: in group A, an alternative monotherapy with a second AED was employed; in group B, add-on treatment with a second AED was employed. The primary outcome was the percentage of seizure-free patients during a two-month period after six months of treatment. The secondary outcomes were: (i) the percentage of patients achieving a 50% reduction in the number of seizures at six months; (ii) the quality of life based on the Quality Of Life In Epilepsy scale; and (iii) tolerability. A total of 143 neurologists were included and randomised, and 264 patients were evaluated. At six months, the primary outcome was 51% in group A and 45% in group B (p=0.34). The percentage of patients achieving a 50% reduction in the number of seizures at six months was 76% in group A and 84% in group B (p=0.53). The quality of life and the tolerability did not significantly differ between the two groups. Alternative monotherapy or early treatment initiation with another AED drug resulted in similar efficacy, and the side effects associated with monotherapy and combined therapies were similar, which suggests that individual susceptibility is more important than the number and burden of AEDs used.

    This is an updated version of the original Cochrane Review published in Issue 2, 2002 and its subsequent updates in 2010 and 2015.Epilepsy is a common neurological condition in which recurrent, unprovoked seizures are caused by abnormal electrical discharges from the brain. It is believed that with effective drug treatment, up to 70% of individuals with active epilepsy have the potential to become seizure-free and go into long-term remission shortly after starting drug therapy with a single antiepileptic drug in monotherapy.Worldwide, carbamazepine and phenytoin are commonly-used broad spectrum antiepileptic drugs, suitable for most epileptic seizure types. Carbamazepine is a current first-line treatment for partial onset seizures in the USA and Europe. Phenytoin is no longer considered a first-line treatment due to concerns over adverse events associated with its use, but the drug is still commonly used in low- to middle-income countries because of its low cost. No consistent differences in efficacy have been found between carbamazepine and phenytoin in individual trials, although the confidence intervals generated by these studies are wide. Differences in efficacy may therefore be shown by synthesising the data of the individual trials. To review the time to withdrawal, six- and 12-month remission, and first seizure with carbamazepine compared to phenytoin, used as monotherapy in people with partial onset seizures (simple partial, complex partial, or secondarily generalised tonic-clonic seizures), or generalised tonic-clonic seizures, with or without other generalised seizure types. For the latest update we searched the Cochrane Epilepsy Group's Specialised Register (1st November 2016), the Cochrane Central Register of Controlled Trials (CENTRAL) via the Cochrane Register of Studies Online (CRSO, 1st November 2016), MEDLINE (Ovid, 1946 to 1 November 2016), ClinicalTrials.gov (1 November 2016), and the World Health Organization (WHO) International Clinical Trials

    Effectiveness and side-effect profile data on pharmacotherapy for daytime sleepiness in central hypersomnias are based largely upon randomized controlled trials. Evidence regarding the use of combination therapy is scant. The aim of this study was to examine the effectiveness and occurrence of drug-related side effects of these drugs in routine clinical practice. Adult patients diagnosed with a central hypersomnia during a 54-month period at a tertiary sleep disorders centre were identified retrospectively. Side effects were recorded at every follow-up visit. A total of 126 patients, with 3275 patient-months of drug exposure, were categorized into narcolepsy type 1 (n = 70), narcolepsy type 2 (n = 47) and idiopathic hypersomnia (n = 9). Modafinil was the most common drug used as a first-line treatment (93%) and in combination therapy (70%). Thirty-nine per cent of the patients demonstrated a complete, 25% partial and 36% a poor response to treatment. Combination treatment improved daytime sleepiness in 55% of the patients with residual symptoms despite monotherapy. Sixty per cent of patients reported side effects, and 30% reported treatment-limiting side effects. Drugs had similar side-effect incidence (P = 0.363) and their side-effect profile met those reported in the literature. Twenty-seven per cent of the patients received combination treatment and had fewer side effects compared to monotherapy (29.4% versus 60%, respectively, P = 0.001). Monotherapy appears to achieve satisfactory symptom control in most patients with central hypersomnia, but significant side effects are common. Combination therapy appears to be a useful and safe option in patients with refractory symptoms. © 2017 European Sleep Research Society.

    A new mathematical approach to modeling the lines-first parachute unfurling process is presented. The unfurling process is treated as two distinct phases: a suspension-line unfurling phase, during which a massless-spring model of the suspension-line elasticity may be employed; and a canopy unfurling phase, during which a formulation considering suspension-line wave mechanics is employed. Histories of unfurled length and tension at the vehicle obtained using the model are compared with flight test data, and generally good agreement is observed.

    The risks of low bone mineral density, osteoporosis and fractures, are major concerns in postmenopausal women. Although postmenopausal hormone therapy is effective for reducing these risks, safety issues have been raised by the results of studies such as the Women's Health Initiative. Although there are scientifically valid reasons to be wary of the general applicability of the Women's Health Initiative findings, the study has underscored the continuing need for research into new forms of menopausal hormone therapy. Low-dose transdermal estrogen monotherapy can preserve bone density while relieving vasomotor symptoms. Transdermal administration may offer advantages, including lack of first-pass liver metabolism, which permits the use of lower doses and avoids a negative impact on the lipid profile. Moreover, a recently published 2-year study of ultra-low-dose transdermal estrogen monotherapy in an older population similar to that of the WHI reported significant increases in bone mineral density, accompanied by significant reductions in markers of bone turnover, with no increased risk of endometrial hyperplasia or other side effects. Additional studies are warranted to shed further light on the possible benefits of low-dose estrogen monotherapy for the prevention of bone loss in postmenopausal women.

  16. Designing clinical trials to assess antiepileptic drugs as monotherapy : difficulties and solutions.

    2008-01-01

    Designing monotherapy trials in epilepsy is fraught with many hurdles, including diagnostic and classification difficulties, sparse information regarding the natural history of the disorder, and ethical objections to the use of placebo or a suboptimal comparator in a condition where the consequences of therapeutic failure can be serious. These issues are further complicated by regulatory differences between the US and the EU.In the US, the FDA considers that evidence of efficacy requires demonstration of superiority to a comparator. Because available antiepileptic drugs possess relatively high efficacy, in most settings it is unrealistic to expect that a new treatment will be superior to a standard treatment used at optimized dosages. To circumvent this problem, trial designs have been developed whereby patients in the control group are assigned to receive a suboptimal comparator and are required to exit from the trial if seizure deterioration occurs. This allows demonstration of a between-group difference in efficacy endpoints, such as time to exit or time to first seizure. Although these trials have come under increasing criticism because of ethical concerns, extensive information is now available on the outcome of patients with chronic epilepsy randomized to suboptimal treatment in similarly designed conversion to monotherapy trials. This has allowed the construction of a dataset of historical controls against which response to a fully active treatment can be compared. A number of studies using this novel approach are now in progress.In the EU, in addition to requiring data on conversion to monotherapy in refractory patients, the European Medicines Agency stipulates that a monotherapy indication in newly diagnosed epilepsy can only be granted if a candidate drug has shown at least a similar benefit/risk balance compared with an acknowledged standard at its optimal use during an assessment period of no less than 1 year. This has led to the implementation of

    Purpose BIRCH was designed to examine the efficacy of atezolizumab, a humanized anti-programmed death-ligand 1 (PD-L1) monoclonal antibody, in advanced non-small-cell lung cancer (NSCLC) across lines of therapy. Patients were selected on the basis of PD-L1 expression on tumor cells (TC) or tumor-infiltrating immune cells (IC). Patients and Methods Eligible patients had advanced-stage NSCLC, no CNS metastases, and zero to two or more lines of prior chemotherapy. Patients whose tumors expressed PD-L1 using the SP142 immunohistochemistry assay on ≥ 5% of TC or IC (TC2/3 or IC2/3 [TC or IC ≥ 5% PD-L1-expressing cells, respectively]) were enrolled. Atezolizumab 1,200 mg was administered intravenously every 3 weeks. Efficacy-evaluable patients (N = 659) comprised three cohorts: first line (cohort 1; n = 139); second line (cohort 2; n = 268); and third line or higher (cohort 3; n = 252). The primary end point was independent review facility-assessed objective response rate (ORR; Response Evaluation Criteria in Solid Tumors [RECIST] version 1.1). Secondary end points included median duration of response, progression-free survival, and overall survival (OS). Results BIRCH met its primary objective of demonstrating a significant ORR versus historical controls. With a minimum of 12 months of follow-up, the independent review facility-assessed ORR was 18% to 22% for the three cohorts, and 26% to 31% for the TC3 or IC3 subgroup; most responses are ongoing. Responses occurred regardless of EGFR or KRAS mutation status. The median OS from an updated survival analysis (minimum of 20 month follow up) for cohort 1 was 23.5 months (26.9 months for TC3 or IC3 patients); the median OS in cohorts 2 and 3 was 15.5 and 13.2 months, respectively. The safety profile was similar across cohorts and consistent with previous atezolizumab monotherapy trials. Conclusion BIRCH demonstrated responses with atezolizumab monotherapy in patients with PD-L1-selected advanced NSCLC, with good

    Background Simplification of antiretroviral treatment (ART) with darunavir/ritonavir (DRV/r) monotherapy has achieved sustained suppression of plasma viral load (pVL) in clinical trials; however, its effectiveness and safety profile has not been evaluated in routine clinical practice. Methodology/Principal Findings We performed a retrospective cohort analysis of HIV-1-infected patients who initiated DRV/r monotherapy once daily with a pVL <50 copies/mL under ART and at least 1 subsequent follow-up visit in our clinic. The primary study endpoints were the percentage of patients with virological failure (VF, defined as 2 consecutive pVL>50 copies/mL) at week 48, and time to VF. Other causes of treatment discontinuation and changes in lipid profile were evaluated up to week 48. Ninety-two patients were followed for a median (IQR) of 73 (57–92) weeks. The median baseline and nadir CD4+ T-cell counts were 604 (433–837) and 238 (150–376) cells/mm3, respectively. Patients had previously received a median of 5 (3–9) ART lines and maintained a pVL<50 copies/mL for a median of 76 (32–176) weeks before initiating DRV/r monotherapy. Nine (9.8%) patients developed VF at week 48; time to VF was 47.1 (IQR: 36.1–47.8) weeks among patients with VF. Other reasons for changing ART were gastrointestinal disturbances (n = 3), rash (n = 1), and impaired CD4 recovery (n = 2). Median low-density lipoprotein cholesterol levels increased from 116.1 mg/dL at baseline to 137.3 mg/dL at 48 weeks (p = 0.001). Conclusions/Significance Treatment simplification with DRV/r monotherapy seems safe and effective in routine clinical practice. Further research is needed to elucidate the effect of DRV/r monotherapy on cholesterol levels. PMID:22666357

    Importance Merkel cell carcinoma (MCC) is an aggressive skin cancer that is associated with poor survival outcomes in patients with distant metastatic disease. Results of part A of the JAVELIN Merkel 200 trial (avelumab in patients with Merkel cell carcinoma) showed that avelumab, an anti–programmed cell death ligand 1 (PD-L1) antibody, demonstrated efficacy in second-line or later treatment of patients with metastatic MCC (mMCC). Objective To evaluate the efficacy and safety of avelumab as first-line treatment for patients with distant mMCC. Design, Setting, and Participants JAVELIN Merkel 200 part B is an international, multicenter, single-arm, open-label clinical trial of first-line avelumab monotherapy. Eligible patients were adults with mMCC who had not received prior systemic treatment for metastatic disease. Patients were not selected for PD-L1 expression or Merkel cell polyomavirus status. Data were collected from April 15, 2016, to March 24, 2017, and enrollment is ongoing. Interventions Patients received avelumab, 10 mg/kg, by 1-hour intravenous infusion every 2 weeks until confirmed disease progression, unacceptable toxic effects, or withdrawal occurred. Main Outcomes and Measures Tumor status was assessed every 6 weeks and evaluated by independent review committee per Response Evaluation Criteria in Solid Tumors version 1.1. The primary end point was durable response, defined as an objective response with a duration of at least 6 months. Secondary end points include best overall response, duration of response, progression-free survival, safety, and tolerability. Results As of March 24, 2017, 39 patients were enrolled (30 men and 9 women; median age, 75 years [range, 47-88 years]), with a median follow-up of 5.1 months (range, 0.3-11.3 months). In a preplanned analysis, efficacy was assessed in 29 patients with at least 3 months of follow-up; the confirmed objective response rate was 62.1% (95% CI, 42.3%-79.3%), with 14 of 18 responses (77.8%) ongoing

    To assess the overall safety of lixisenatide monotherapy in Japanese patients with type 2 diabetes mellitus. Patients with type 2 diabetes mellitus, previously treated with ≤1 oral antidiabetic drug, were enrolled in an uncontrolled, open-label, single-arm study over 24 and 52 weeks. Any oral antidiabetic drug treatment was stopped at the start of the 6-week run-in period. From baseline, patients received once-daily lixisenatide monotherapy (10 μg for 1 week, 15 μg for 1 week, 20 μg thereafter) for 52 weeks (first 140 patients enrolled) or 24 weeks (subsequently enrolled patients). The primary end-point was safety over 24 and 52 weeks. Secondary efficacy end-points included absolute change in glycated hemoglobin, fasting plasma glucose and bodyweight from baseline. Of 428 patients screened, 361 and 140 were treated for 24 and 52 weeks, respectively; 88.4 and 90.0% completed treatment. During the 24- and 52-week treatment periods, 268/361 (74.2%) and 117/140 (83.6%) patients, respectively, had treatment-emergent adverse events; the most frequently reported was nausea (33.2 and 31.4%, respectively). The risk of severe hypoglycemia was low; only one case was reported. Lixisenatide treatment resulted in a decrease in mean glycated hemoglobin A1c (-0.98 and -0.86%), fasting plasma glucose (-1.05 and -0.85 mmol/L), and bodyweight (-1.33 and -1.48 kg) for the 24- and 52-week treatment periods, respectively. Once-daily lixisenatide monotherapy was associated with a safety profile in line with the glucagon-like peptide-1 receptor agonist class, and improved glycemic control in Japanese patients with type 2 diabetes mellitus. © 2017 The Authors.

    Everolimus-based therapy and endocrine monotherapy are used among postmenopausal women with hormone receptor-positive human epidermal growth factor receptor-2 negative (HR+/HER2-) metastatic breast cancer (mBC) whose disease progressed or recurred on a non-steroidal aromatase inhibitor (NSAI). However, limited evidence exists regarding the real-world comparative effectiveness of these agents. This retrospective chart review examined postmenopausal HR+/HER2- mBC patients in community-based oncology practices who received everolimus-based therapy or endocrine monotherapy (index therapy) as any line of therapy for mBC between 1 July 2012 and 15 April 2013 after NSAI failure. Time on treatment (TOT), progression-free survival (PFS), and time to chemotherapy (TTC) from index therapy initiation were compared using Kaplan-Meier analyses and Cox proportional hazards models adjusting for baseline characteristics. A total of 243 and 270 patients received everolimus-based therapy or endocrine monotherapy in a quota-based sample. Patients treated with everolimus-based therapy had a higher proportion of visceral metastases, high tumor burden, and use of prior chemotherapies for mBC. After adjusting for baseline characteristics, everolimus-based therapy was associated with significantly longer TOT (HR = 0.67, 95% CI: 0.51-0.87) and PFS (HR = 0.75, 95% CI: 0.57-0.98) than endocrine monotherapy. No significant difference was found between everolimus-based therapy and endocrine monotherapy in TTC (HR = 0.81, 95% CI: 0.52-1.27). Results stratified by line of therapy were generally consistent with the overall results. Limitations include recall and information bias with potentially absent or erroneous chart data, unobserved factors due to non-randomization, inability to measure outcome assessments paired with measuring outcomes prior to exposures, and potential patient selection bias associated with chart review.

    Purpose Eslicarbazepine acetate (ESL) is a once-daily (QD) oral antiepileptic drug (AED) indicated for partial-onset seizures (POS). Clinical studies of gradual conversion to ESL 1,200 and 1,600 mg QD monotherapies were previously conducted in patients with POS who were not well-controlled by 1 or 2 AEDs. This report describes modeling and simulation of plasma eslicarbazepine (primary active metabolite of ESL) concentrations and time to monotherapy study exit to predict efficacy for conversion to ESL monotherapy at a lower dose of 800 mg, as an option for patients requiring or not tolerating higher doses since this regimen is effective in adjunctive therapy for POS. Patients and methods A previously developed population pharmacokinetic model for ESL monotherapy was used to predict minimum plasma eslicarbazepine concentration (Cmin) in 1,500 virtual patients taking 1 (n=1,000) or 2 (n=500) AEDs at baseline, treated with ESL 400 mg QD for 1 week, followed by 800 mg QD for 17 weeks (similar to ESL monotherapy trials where the other AEDs were withdrawn during the first 6 weeks following titration to the randomized ESL dose). Model-predicted Cmin as a time-varying covariate and number of baseline AEDs were used to determine the weekly probability of each patient meeting exit criteria (65.3% threshold) indicative of worsening seizure control in 500 simulated ESL monotherapy trials. A previously developed extended Cox proportional hazards exposure–response model was used to relate time-varying eslicarbazepine exposure to the time to study exit. Results For virtual patients receiving ESL monotherapy (800 mg QD), the 95% upper prediction limit for exit rate at 112 days of 34.9% in patients taking 1 AED at baseline was well below the 65.3% threshold from historical control trials, while the estimate for patients taking 2 AEDs (70.6%) was slightly above the historical control threshold. Conclusion This model-based assessment supports conversion to ESL 800 mg QD monotherapy

    Eslicarbazepine acetate (ESL) is a once-daily (QD) oral antiepileptic drug (AED) indicated for partial-onset seizures (POS). Clinical studies of gradual conversion to ESL 1,200 and 1,600 mg QD monotherapies were previously conducted in patients with POS who were not well-controlled by 1 or 2 AEDs. This report describes modeling and simulation of plasma eslicarbazepine (primary active metabolite of ESL) concentrations and time to monotherapy study exit to predict efficacy for conversion to ESL monotherapy at a lower dose of 800 mg, as an option for patients requiring or not tolerating higher doses since this regimen is effective in adjunctive therapy for POS. A previously developed population pharmacokinetic model for ESL monotherapy was used to predict minimum plasma eslicarbazepine concentration ( C min ) in 1,500 virtual patients taking 1 (n=1,000) or 2 (n=500) AEDs at baseline, treated with ESL 400 mg QD for 1 week, followed by 800 mg QD for 17 weeks (similar to ESL monotherapy trials where the other AEDs were withdrawn during the first 6 weeks following titration to the randomized ESL dose). Model-predicted C min as a time-varying covariate and number of baseline AEDs were used to determine the weekly probability of each patient meeting exit criteria (65.3% threshold) indicative of worsening seizure control in 500 simulated ESL monotherapy trials. A previously developed extended Cox proportional hazards exposure-response model was used to relate time-varying eslicarbazepine exposure to the time to study exit. For virtual patients receiving ESL monotherapy (800 mg QD), the 95% upper prediction limit for exit rate at 112 days of 34.9% in patients taking 1 AED at baseline was well below the 65.3% threshold from historical control trials, while the estimate for patients taking 2 AEDs (70.6%) was slightly above the historical control threshold. This model-based assessment supports conversion to ESL 800 mg QD monotherapy for POS in adults taking 1 AED. For patients

    To determine the factors that attract and retain Registered Nurses in the first-line nurse manager role. The first-line nurse manger role is pivotal in health-care organisations. National demographics suggest that Canada will face a first-line nurse manager shortage because of retirement in the next decade. Determination of factors that attract and retain Registered Nurses will assist organisations and policy makers to employ strategies to address this shortage. The study used an exploratory, descriptive qualitative approach, consisting of semi-structured individual interviews with 11 Registered Nurses in first-line nurse manager roles. The findings revealed a discrepancy between the factors that attract and retain Registered Nurses in the first-line nurse manager role, underscored the importance of the mentor role and confirmed the challenges encountered by first-line nurse managers practicing in the current health-care environment. The first-line nurse manager role has been under studied. Further research is warranted to understand which strategies are most effective in supporting first-line nurse managers. Strategies to support nurses in the first-line nurse manager role are discussed for the individual, programme, organisation and health-care system/policy levels. © 2013 John Wiley & Sons Ltd.

    Limited post-crizotinib treatment options for ALK-positive non-small cell lung cancer (NSCLC) might lead to poor survival and high economic burden. To evaluate real-world treatment patterns, overall survival (OS), and costs following crizotinib discontinuation. This study used chart review and claims data. First, 27 participating US oncologists reviewed medical records of ALK-positive NSCLC patients who discontinued crizotinib monotherapy and reported patient demographic and clinical information, including post-crizotinib treatment and mortality. OS was estimated using Kaplan-Meier analyses. Second, three large administrative US claims databases were pooled. NSCLC patients were selected if they discontinued crizotinib monotherapy. Post-crizotinib costs were analyzed separately for patients who did or did not discontinue antineoplastic treatment after crizotinib monotherapy. All data were collected prior to ceritinib approval for this patient population. A total of 119 ALK-positive NSCLC patients discontinued crizotinib monotherapy. Upon discontinuation, 42% had no additional antineoplastic treatment and 13% received radiation therapy only. The median OS post-crizotinib was 61 days; patients with brain metastases had shorter OS than those who did not (44 vs. 69 days, P = 0.018), and patients without further antineoplastic treatment had shorter OS than those who did (17 vs. 180 days, P < 0.001). From claims data, 305 ALK-positive NSCLC patients discontinued crizotinib monotherapy. After discontinuation, 72% had no additional antineoplastic treatment. Among patients who continued antineoplastic treatment, monthly healthcare costs averaged $22,160, driven by pharmacy ($9202), inpatient ($6419), and outpatient radiotherapy ($2888) and imaging ($1179) costs. Among patients who discontinued any antineoplastic treatment, monthly healthcare costs averaged $3423, mostly driven by inpatient costs ($2074). After crizotinib monotherapy, most patients either received

    Systemic juvenile idiopathic arthritis (sJIA) is an auto-inflammatory disease characterized by fever, arthritis, and ≥1 of rash, generalized lymphadenopathy, hepato/splenomegaly, and serositis. Non-steroidal anti-inflammatory drugs (NSAIDs) are among the initial treatments of sJIA, but there is currently no evidence indicating which children should undergo a trial of NSAID monotherapy and which should not. Our objective is to identify presentation characteristics which are associated with response and lack of response to a trial of NSAID monotherapy. This is a retrospective single-center cohort study of children diagnosed with sJIA from 2000 to 2014. Patient demographics and disease characteristics were investigated to identify predictors of response to NSAID monotherapy. Eighty-seven children were newly diagnosed with sJIA 2000-2014. Thirteen of the 51 children who received NSAID monotherapy achieved clinically inactive disease (CID) without other medications. Age at presentation (≤8 years old), initial joint count (≤5), and C-reactive protein (CRP) (≤13 mg/dL) at diagnosis were associated with achievement of CID on NSAIDs alone. Physicians were less likely to trial NSAID monotherapy if the patient had either serositis or macrophage activation syndrome (MAS) at diagnosis. Ultimate achievement of CID and time to CID were not significantly affected by whether the patient received a trial of NSAID monotherapy. While a subset of children with sJIA can achieve CID with NSAID monotherapy, we recommend against a trial in patients who are >8 years old, with >5 joints involved, or with CRP > 13 mg/dL. Patients who undergo a trial of NSAID monotherapy should follow up within 2-4 weeks to evaluate for possible need for drug escalation. Clinical trials are necessary to confirm these findings.

    We evaluated the incremental cost-effectiveness of cabergoline compared with levodopa monotherapy in patients with early Parkinson's disease (PD) in the German healthcare system. The study design was based on cost-effectiveness analysis using a Markov model with a 10-year time horizon. Model input data was based on a clinical trial "Early Treatment of PD with Cabergoline" as well as on cost data of a German hospital/office-based PD network. Direct and indirect medical and nonmedical costs were included. Outcomes were costs, disease stage, cumulative complication incidence, and mortality. An annual discount rate of 5% was applied and the societal perspective was chosen. The target population included patients in Hoehn and Yahr Stages I to III. It was found that the occurrence of motor complications was significantly lower in patients on cabergoline monotherapy. For patients aged >/=60 years of age, cabergoline monotherapy was cost effective when considering costs per decreased UPDRS score. Each point decrease in the UPDRS (I-IV) resulted in costs of euro;1,031. Incremental costs per additional motor complication-free patient were euro;104,400 for patients <60 years of age and euro;57,900 for patients >/=60 years of age. In conclusion, this decision-analytic model calculation for PD was based almost entirely on clinical and observed data with a limited number of assumptions. Although costs were higher in patients on cabergoline, the corresponding cost-effectiveness ratio for cabergoline was at least as favourable as the ratios for many commonly accepted therapies.

    Background: It is important to choose an appropriate antiepileptic drug (AED) to manage partial epilepsy. Traditional AEDs, such as carbamazepine (CBZ) and valproate (VPA), have been proven to have good therapeutic effects. However, in recent years, a variety of new AEDs have increasingly been used as first-line treatments for partial epilepsy. As the studies regarding the effectiveness of new drugs and comparisons between new AEDs and traditional AEDs are few, it is determined that these are areas in need of further research. Accordingly, this study investigated the long-term effectiveness of six AEDs used as monotherapy in patients with partial epilepsy. Methods: This is a retrospective, long-term observational study. Patients with partial epilepsy who received monotherapy with one of six AEDs, namely, CBZ, VPA, topiramate (TPM), oxcarbazepine (OXC), lamotrigine (LTG), or levetiracetam (LEV), were identified and followed up from May 2007 to October 2014, and time to first seizure after treatment, 12-month remission rate, retention rate, reasons for treatment discontinuation, and adverse effects were evaluated. Results: A total of 789 patients were enrolled. The median time of follow-up was 56.95 months. CBZ exhibited the best time to first seizure, with a median time to first seizure of 36.06 months (95% confidential interval: 30.64–44.07). CBZ exhibited the highest 12-month remission rate (85.55%), which was significantly higher than those of TPM (69.38%, P = 0.006), LTG (70.79%, P = 0.001), LEV (72.54%, P = 0.005), and VPA (73.33%, P = 0.002). CBZ, OXC, and LEV had the best retention rate, followed by LTG, TPM, and VPA. Overall, adverse effects occurred in 45.87% of patients, and the most common adverse effects were memory problems (8.09%), rashes (7.76%), abnormal hepatic function (6.24%), and drowsiness (6.24%). Conclusion: This study demonstrated that CBZ, OXC, and LEV are relatively effective in managing focal epilepsy as measured by time to first seizure

    Carbamazepine (CBZ) is used as the first line of treatment of Complex Partial Seizures (CPS) in the Epilepsy Clinic, Neurology Department of Kuala Lumpur Hospital (KLH). More than 30% of the patients remain drug resistant to CBZ mono-therapy. CBZ is transported by the P-glycoprotein (P-gp). The P-gp encoded by the ABCB1 and ABCC2 genes are expressed in drug resistant patients with epilepsy. A few studies have shown significant association between CBZ resistant epilepsy and Linkage Disequilibrium (LD) with adjacent polymorphisms of these genes. Our study is aimed at determining the correlation between patients' response to CBZ mono-therapy to Single Nucleotide Polymorphisms G2677T and C3435T of the ABCB1 gene as well as G1249A and -24C>T of the ABCC2 gene. 314 patients with CPS were recruited from the Neurology Department of the KLH based on stringent inclusion and exclusion criteria, of whom 152 were responders and the other 162 were non-responders. DNA was extracted from their blood samples and Taqman technology for allelic discrimination was performed. Results were described as genotype frequencies. The SHEsis analysis platform was used to calculate linkage disequilibrium index and infer haplotype frequencies. Haploview was used to do permutation test to obtain a corrected p-value. Resistance to treatment with CBZ mono-therapy was significantly associated with the 2677TT and the 3435TT genotypes while it was not significantly associated with the G1249A and -24C>T polymorphisms. The GCGC haplotype combination of the 2677G>T, 3435C>T, 1249G>A and -24C>T respectively was found to be extremely significant (p = 1.10e-20) with good drug response to CBZ mono-therapy. Linkage disequilibrium between the 2677G>T, 3435C>T, 1249G>A and -24C>T SNPs may be used as a reliable screening marker to determine the treatment outcome of CBZ mono-therapy with CPS irrespective of race or gender.

    To determine the force needed to extract a drop from a range of current prostaglandin monotherapy eye droppers and how this related to the comfortable and maximum pressure subjects could exert. The comfortable and maximum pressure subjects could apply to an eye dropper constructed around a set of cantilevered pressure sensors and mounted above their eye was assessed in 102 subjects (mean 51.2±18.7 years), repeated three times. A load cell amplifier, mounted on a stepper motor controlled linear slide, was constructed and calibrated to test the force required to extract the first three drops from 13 multidose or unidose latanoprost medication eye droppers. The pressure that could be exerted on a dropper comfortably (25.9±17.7 Newtons, range 1.2-87.4) could be exceeded with effort (to 64.8±27.1 Newtons, range 19.9-157.8; F=19.045, p<0.001), and did not differ between repeats (F=0.609, p=0.545). Comfortable and maximum pressures exerted were correlated (r=0.618, p<0.001), neither were influenced strongly by age (r=0.138, p=0.168; r=-0.118, p=0237, respectively), but were lower in women than in men (F=12.757, p=0.001). The force required to expel a drop differed between dropper designs (F=22.528, p<0.001), ranging from 6.4 Newtons to 23.4 Newtons. The force needed to exert successive drops increased (F=36.373, p<0.001) and storing droppers in the fridge further increased the force required (F=7.987, p=0.009). Prostaglandin monotherapy droppers for glaucoma treatment vary in their resistance to extract a drop and with some a drop could not be comfortably achieved by half the population, which may affect compliance and efficacy.

    Nursing is acknowledged as being the art and science of caring. According to the theory of nursing as caring, all persons are caring but not every behaviour of a person is caring. Caring behaviours in the relationship between first-line nurse managers and Registered Nurses have been studied to a lesser extent than those that exist between patients and nurses. Caring behaviour of first-line nurse managers from the perspective of Registered Nurses is as of yet unknown. Identifying caring behaviours may be useful as a reference for first-line nurse managers caring for nurses in a way that nurses prefer. To explore first-line nurse managers' caring behaviours from the perspective of Registered Nurses in mainland China. Qualitative study, using descriptive phenomenological approach. Fifteen Registered Nurses recruited by purposive sampling method took part in in-depth interviews. Data were analysed according to Colaizzi's technique. Three themes of first-line nurse managers' caring behaviours emerged: promoting professional growth, exhibiting democratic leadership and supporting work-life balance. A better understanding of the first-line nurse managers' caring behaviours is recognised. The three kinds of behaviours have significant meaning to nurse managers. Future research is needed to describe what first-line nurse managers can do to promote nurses' professional growth, increase the influence of democratic leadership, as well as support their work-life balance. © 2015 Nordic College of Caring Science.

    Clinical evidence demonstrates coadministration of tumour necrosis factor inhibitor (TNFi) agents and methotrexate (MTX) is more efficacious than administration of TNFi agents alone in patients with rheumatoid arthritis, leading to the perception that coadministration of MTX with all biologic agents or oral disease-modifying antirheumatic drugs is necessary for maximum efficacy. Real-life registry data reveal approximately one-third of patients taking biologic agents use them as monotherapy. Additionally, an analysis of healthcare claims data showed that when MTX was prescribed in conjunction with a biologic agent, as many as 58% of patients did not collect the MTX prescription. Given this discrepancy between perception and real life, we conducted a review of the peer-reviewed literature and rheumatology medical congress abstracts to determine whether data support biologic monotherapy as a treatment option for patients with rheumatoid arthritis. Our analysis suggests only for tocilizumab is there evidence that the efficacy of biologic monotherapy is comparable with combination therapy with MTX. PMID:23918035

    The high genetic barrier to resistance of dolutegravir might allow for its use as maintenance monotherapy in patients with HIV. We investigated whether dolutegravir monotherapy was non-inferior to combination antiretroviral therapy (ART) for maintaining virological suppression in patients with HIV-1 infection successfully treated with combination ART. We did this open-label, phase 2, randomised non-inferiority trial at two medical centres in the Netherlands. Eligible patients (aged ≥18 years) were on combination ART, had been virologically suppressed (HIV RNA <50 copies per mL) for at least 6 months, and had CD4 nadirs of 200 cells per μL or higher, HIV RNA zeniths of 100 000 copies per mL or less, and no history of virological failure. Patients were randomly assigned (1:1), via a web-based block randomisation method (variable block sizes of 4 and 6), to switch to dolutegravir monotherapy (50 mg once a day) either immediately or after a delay of 24 weeks of continued combination ART. Randomisation was stratified by HIV RNA zenith (<50 000 copies per mL vs 50 000-99 999 copies per mL). Investigators and patients were not masked to group allocation. The primary endpoint was the proportion of patients with plasma HIV RNA viral loads of less than 200 copies per mL at week 24, with a non-inferiority margin of 12%. We did analyses in the on-treatment and intention-to-treat populations. This trial is registered with ClinicalTrials.gov, NCT02401828. Between March 10, 2015, and Feb 4, 2016, we randomly assigned 51 patients to the immediate switch group and 53 patients to the delayed switch group. One patient who received immediate monotherapy discontinued treatment at week 12 because of disturbed sleep. At week 24, dolutegravir monotherapy was non-inferior to combination ART, with plasma HIV RNA loads of 200 copies per mL or higher observed in 2% (1/50) of patients in the immediate switch group and in no patients in the delayed switch group (difference 2%, 95% CI

    Intraurethral alprostadil and oral sildenafil are useful in selected patients. However, there continues to be a significant treatment failure rate. Since their mechanisms of action are different, we wanted to evaluate the effectiveness of combination therapy. Of 214 patients treated for erectile dysfunction (ED), 65 were not fully satisfied with the firmness of their erections via monotherapy. Responses were evaluated using the International Index for Erectile Function (IIEF) questionnaire before and after treatment. Group I consisted of 33 patients who tried maximal dose intraurethral alprostadil monotherapy initially, followed by the maximal dose of sildenafil monotherapy, and were still unsatisfied. Group II consisted of 32 patients who tried the maximal dose sildenafil monotherapy initially, followed by the maximal dose of alprostadil monotherapy, and were also unsatisfied. There 65 patients then underwent combination therapy. 60 out of the 65 patients stated they were satisfied with combination therapy. Questionnaire scores for erectile function were 23.1+/-2.0 (114%) for combination therapy vs. 19.2+/-1.8 (77%) and 15.2+/-1.6 (41%) for sildenafil and alprostadil monotherapies (p<0.05). There were no significant differences in responses between the two groups. The men also reported improvement in intercourse and overall satisfaction. Combination therapy may be an option for motivated patients who have a suboptimal response from monotherapy.

    Because of general unavailability of tetracycline, common adverse effects, and complicated administration, the clinical application of bismuth quadruple therapy often faces difficulties. Whether the combination of minocycline and amoxicillin can replace tetracycline and metronidazole for Helicobacter pylori eradication remains unclear. This study was to determine the efficacy, compliance, and safety of rabeprazole, minocycline, amoxicillin, and bismuth (RMAB) therapy as first-line and second-line regimens. Between July 2013 and December 2015, a total of 160 patients in first-line and 70 patients in second-line therapies received rabeprazole 10 mg, minocycline 100 mg, amoxicillin 1000 mg, and bismuth potassium citrate 220 mg twice daily for 14 days. Eradication status was assessed 6-12 weeks after treatment. RMAB therapy achieved the eradication rates of 87.5% (95% confidence interval, 81.9-92.5%, intention-to-treat analysis), 90.9% (85.7-95.5%, modified intention-to-treat analysis), and 92.6% (88.5-96.6%, per-protocol analysis) in first-line therapy in a setting with high antibiotic resistance rates (amoxicillin 3.4%, clarithromycin 39.7%, metronidazole 60.3%, levofloxacin 36.2%, tetracycline 3.4%, and minocycline 6.9%). As for second-line therapy, the eradication rates were 82.9% (74.3-91.4%, intention-to-treat analysis), 86.6% (77.6-94.0%, modified intention-to-treat analysis), and 89.1% (81.3-95.3%, per-protocol analysis). Totally, 24.0% patients had adverse effects, 2.2% discontinued medications, and good compliance was achieved in 94.7%. Poor compliance and minocycline resistance were identified as the risk factors for treatment failure. Significant differences in efficacy existed among the groups of both sensitive (48/51 and 18/20), isolated amoxicillin resistance (1/1 and 0/0), isolated minocycline resistance (2/3 and 1/1), and dual resistance (0/1 and 0/1) in both first-line (p = .004) and second-line (p = .035) therapies.

    Further options for monotherapy are needed to treat newly diagnosed epilepsy in adults. We assessed the efficacy, safety, and tolerability of lacosamide as a first-line monotherapy option for these patients. In this phase 3, randomised, double-blind, non-inferiority trial, patients from 185 epilepsy or general neurology centres in Europe, North America, and the Asia Pacific region, aged 16 years or older and with newly diagnosed epilepsy were randomly assigned in a 1:1 ratio, via a computer-generated code, to receive lacosamide monotherapy or controlled-release carbamazepine (carbamazepine-CR) twice daily. Patients, investigators, and trial personnel were masked to treatment allocation. From starting doses of 100 mg/day lacosamide or 200 mg/day carbamazepine-CR, uptitration to the first target level of 200 mg/day and 400 mg/day, respectively, took place over 2 weeks. After a 1-week stabilisation period, patients entered a 6-month assessment period. If a seizure occurred, the dose was titrated to the next target level (400 or 600 mg/day for lacosamide and 800 or 1200 mg/day for carbamazepine-CR) over 2 weeks with a 1-week stabilisation period, and the 6-month assessment period began again. Patients who completed 6 months of treatment and remained seizure-free entered a 6-month maintenance period on the same dose. The primary efficacy outcome was the proportion of patients remaining free from seizures for 6 consecutive months after stabilisation at the last assessed dose. The predefined non-inferiority criteria were -12% absolute and -20% relative difference between treatment groups. This trial is registered with ClinicalTrials.gov, number NCT01243177. The trial was done between April 27, 2011, and Aug 7, 2015. 888 patients were randomly assigned treatment. 444 patients taking lacosamide and 442 taking carbamazepine-CR were included in the full analysis set (took at least one dose of study treatment), and 408 and 397, respectively, were included in the per

    Purpose To compare the rates of antipsychotic response, remission, and relapse in patients with schizophrenia treated with olanzapine or other antipsychotics in usual clinical care in Japan. Patients and methods This analysis of a 12-month, prospective, noninterventional study examined outcomes for 1,089 inpatients and outpatients with schizophrenia who initiated antipsychotic monotherapy. All treatment decisions, including medication choice, were left to the discretion of the treating physician. The rates of treatment response, relapse, and 6-month sustained remission were compared between olanzapine monotherapy (OLZ) and other anti-psychotic monotherapy (OAN), and between OLZ and other atypical antipsychotic monotherapy (OAT). Visit-wise comparisons of treatment response and remission were examined using repeated-measures logistic regressions. Propensity scores were used to control for potential baseline differences between groups. Results Response rates were higher for OLZ patients and relapse rates were consistently lower for OLZ patients, however the differences were not statistically significant. Rates of 6-month sustained remission were significantly higher for OLZ than OAN patients (P=0.032) and for OLZ than OAT patients (P=0.041). An exploratory analysis of OLZ and OAN comparison found outpatients treated with OLZ or OAN had similar sustained remission rates (OLZ: 22.2%, OAN: 22.8%), while inpatients treated with OLZ had significantly higher sustained remission rates than inpatients treated with OAN (OLZ: 17.1%, OAN: 6.6%, odds ratio [95% confidence interval] =3.54 [2.00–6.25]). Conclusion In usual care in Japan, treating the acute symptoms of schizophrenia with olanzapine was not found to be significantly different for response and relapse rates; however, treatment with olanzapine was found to have significantly greater sustained remission rates than treatment with other antipsychotics. In the inpatient setting, where patients tend to be more severe and

    Background We performed an updated meta-analysis of randomized placebo-controlled trials testing memantine monotherapy for patients with Alzheimer’s disease (AD). Methods The meta-analysis included randomized controlled trials of memantine monotherapy for AD, omitting those in which patients were also administered a cholinesterase inhibitor. Cognitive function, activities of daily living, behavioral disturbances, global function, stage of dementia, drug discontinuation rate, and individual side effects were compared between memantine monotherapy and placebo groups. The primary outcomes were cognitive function and behavioral disturbances; the others were secondary outcomes. Results Nine studies including 2433 patients that met the study’s inclusion criteria were identified. Memantine monotherapy significantly improved cognitive function [standardized mean difference (SMD)=−0.27, 95% confidence interval (CI)=−0.39 to −0.14, p=0.0001], behavioral disturbances (SMD=−0.12, 95% CI=−0.22 to −0.01, p=0.03), activities of daily living (SMD=−0.09, 95% CI=−0.19 to −0.00, p=0.05), global function assessment (SMD=−0.18, 95% CI=−0.27 to −0.09, p=0.0001), and stage of dementia (SMD=−0.23, 95% CI=−0.33 to −0.12, p=0.0001) scores. Memantine was superior to placebo in terms of discontinuation because of inefficacy [risk ratio (RR)=0.36, 95% CI=0.17¬ to 0.74, p=0.006, number needed to harm (NNH)=non significant]. Moreover, memantine was associated with less agitation compared with placebo (RR=0.68, 95% CI=0.49 to 0.94, p=0.02, NNH=non significant). There were no significant differences in the rate of discontinuation because of all causes, all adverse events, and individual side effects other than agitation between the memantine monotherapy and placebo groups. Conclusions Memantine monotherapy improved cognition, behavior, activities of daily living, global function, and stage of dementia and was well-tolerated by AD patients. However, the effect

    Reporting of 'real-world' data on efficacy and tolerability of antiepileptic medications helps to inform physicians on how newer medications perform in the clinical setting, outside of the strict regimens of clinical trials. We report our experience of prescribing lacosamide monotherapy to a diverse range of patients at our epilepsy centre. We performed a single-centre, retrospective review of all patients who had been prescribed lacosamide monotherapy over the last 8 years. Efficacy is pragmatically reported based on reduction of seizure frequency and lacosamide retention rates. We identified 45 patients who were commenced on lacosamide monotherapy. Intent-to-treat analysis demonstrated a 51% (n = 23) 12 month retention rate. Forty percent (n = 18) achieved a greater than 50% reduction in seizure frequency and 35.5% (n = 16) became seizure free. We report real-world data showing a significant reduction in seizure frequency, a moderate rate of retention and an excellent side effect profile in our cohort of patients prescribed lacosamide monotherapy.

    Defective expression of the mismatch repair protein MSH3 is frequently detected in colon cancer, and down-regulation of its expression was found to decrease sensitivity to platinum compounds or poly(ADP-ribose) polymerase inhibitors (PARPi) monotherapy. We have investigated whether MSH3 transfection in MSH3-deficient colon cancer cells confers resistance to oxaliplatin or PARPi and whether their combination restores chemosensitivity. MSH3-deficient/MLH1-proficient colon cancer HCT116(MLH1) cells were transfected with the MSH3 cDNA cloned into the pcDNA3.1(-) vector. MSH3/MLH1-deficient HCT116, carrying MLH1 and MSH3 mutations on chromosome 3 and 5, respectively, and HCT116 in which wild-type MLH1 (HCT116+3), MSH3 (HCT116+5) or both genes (HCT116+3+5) were introduced by chromosome transfer were also tested. Sensitivity to oxaliplatin and to PARPi was evaluated by analysis of clonogenic survival, cell proliferation, apoptosis and cell cycle. MSH3 transfection in HCT116 cells did not confer resistance to oxaliplatin or PARPi monotherapy. MSH3-proficient HCT116+5 or HCT116+3+5 cells, which were more resistant to oxaliplatin and PARPi in comparison with their MSH3-deficient counterparts, expressed higher levels of the nucleotide excision repair ERCC1 and XPF proteins, involved in the resistance to platinum compounds, and lower PARP-1 levels. In all cases, PARPi increased sensitivity to oxaliplatin. Restoring of MSH3 expression by cDNA transfection, rather than by chromosome transfer, did not affect colon cancer sensitivity to oxaliplatin or PARPi monotherapy; PARP-1 levels seemed to be more crucial for the outcome of PARPi monotherapy.

    Summary Background and objectives In ADOPT (A Diabetes Outcomes Prevention Trial), initial monotherapy with rosiglitazone provided more durable glycemic control than metformin or glyburide in patients with recently diagnosed type 2 diabetes. Herein, we examine differences in albumin excretion, renal function (estimated GFR), and BP over 5 years between treatment groups. Design, setting, participants, & measurements A total of 4351 recently diagnosed, drug-naïve patients with type 2 diabetes were treated and followed for up to 5 years with rosiglitazone, metformin, or glyburide and were examined with periodic assessments of albumin/creatinine ratio (ACR), modification of diet in renal disease (MDRD)-estimated GFR, and BP. Results The ACR rose slowly with metformin. It fell with rosiglitazone and less so with glyburide over the first 2 years, and then rose slowly over time. Estimated GFR (eGFR) with all therapies rose into the high normal range over the first 3 to 4 years, more so with rosiglitazone, and then declined, more so with glyburide. Systolic BP was stable over time, values with rosiglitazone being lower, and diastolic BP declined over time, more so with rosiglitazone than with metformin or glyburide. There was no difference among groups in the incidence of emergent albuminuria (ACR ≥30 mg/g), hypertension, or impaired eGFR (<60 ml/min per 1.73 m2). Conclusions Over a 5-year period, initial monotherapy with rosiglitazone retards the rise of ACR compared with metformin, preserves eGFR compared with glyburide, and lowers BP relative to both comparators.

    In 2012, alarmingly high rates of oral artemisinin monotherapy availability and use were detected along Eastern Myanmar, threatening efforts to halt the spread of artemisinin resistance in the Greater Mekong Subregion (GMS), and globally. The aim of this paper is to exemplify how the use of supply side evidence generated through the ACTwatch project shaped the artemisinin monotherapy replacement malaria (AMTR) project's design and interventions to rapidly displace oral artemisinin monotherapy with subsidized, quality-assured ACT in the private sector. The AMTR project was implemented as part of the Myanmar artemisinin resistance containment (MARC) framework along Eastern Myanmar. Guided by outlet survey and supply chain evidence, the project implemented a high-level subsidy, including negotiations with a main anti-malarial distributor, with the aim of squeezing oral artemisinin monotherapy out of the market through price competition and increased availability of quality-assured artemisinin-based combinations. This was complemented with a plethora of demand-creation activities targeting anti-malarial providers and consumers. Priority outlet types responsible for the distribution of oral artemisinin monotherapy were identified by the outlet survey, and this evidence was used to target the AMTR project's supporting interventions. The widespread availability and use of oral artemisinin monotherapy in Myanmar has been a serious threat to malaria control and elimination in the country and across the region. Practical anti-malarial market evidence was rapidly generated and used to inform private sector approaches to address these threats. The program design approach outlined in this paper is illustrative of the type of evidence generation and use that will be required to ensure effective containment of artemisinin drug resistance and progress toward regional and global malaria elimination goals.

    Objective To constitute the third revision of the guidelines for the treatment of bipolar disorder issued by the Korean Medication Algorithm Project for Bipolar Disorder (KMAP-BP 2014). Methods A 56-item questionnaire was used to obtain the consensus of experts regarding pharmacological treatment strategies for the various phases of bipolar disorder and for special populations. The review committee included 110 Korean psychiatrists and 38 experts for child and adolescent psychiatry. Of the committee members, 64 general psychiatrists and 23 child and adolescent psychiatrists responded to the survey. Results The treatment of choice (TOC) for euphoric, mixed, and psychotic mania was the combination of a mood stabilizer (MS) and an atypical antipsychotic (AAP); the TOC for acute mild depression was monotherapy with MS or AAP; and the TOC for moderate or severe depression was MS plus AAP/antidepressant. The first-line maintenance treatment following mania or depression was MS monotherapy or MS plus AAP; the first-line treatment after mania was AAP monotherapy; and the first-line treatment after depression was lamotrigine (LTG) monotherapy, LTG plus MS/AAP, or MS plus AAP plus LTG. The first-line treatment strategy for mania in children and adolescents was MS plus AAP or AAP monotherapy. For geriatric bipolar patients, the TOC for mania was AAP/MS monotherapy, and the TOC for depression was AAP plus MS or AAP monotherapy. Conclusion The expert consensus in the KMAP-BP 2014 differed from that in previous publications; most notably, the preference for AAP was increased in the treatment of acute mania, depression, and maintenance treatment. There was increased expert preference for the use of AAP and LTG. The major limitation of the present study is that it was based on the consensus of Korean experts rather than on experimental evidence. PMID:25750530

    Metformin is used clinically to reduce fasting glucose with minimal effects on postprandial glucose. Postmeal exercise reduces postprandial glucose and may offer additional glucose-lowering benefit beyond that of metformin alone, yet controversy exists surrounding exercise and metformin interactions. It is currently unknown how postmeal exercise and metformin monotherapy in combination will affect postprandial glucose. Thus, we examined the independent and combined effects of postmeal exercise and metformin monotherapy on postprandial glucose. A randomized crossover design was used to assess the influence of postmeal exercise on postprandial glucose excursions in 10 people treated with metformin monotherapy (57 ± 10 yr, HbA 1C  = 6.3 ± 0.6%). Each participant completed the following four conditions: sedentary and postmeal exercise (5 × 10-min bouts of treadmill walking at 60% V̇o 2max ) with metformin and sedentary and postmeal exercise without metformin. Peak postprandial glucose within a 2-h time window and 2-h total area under the curve was assessed after a standardized breakfast meal, using continuous glucose monitoring. Postmeal exercise significantly blunted 2-h peak ( P = 0.001) and 2-h area under the curve ( P = 0.006), with the lowest peak postprandial glucose excursion observed with postmeal exercise and metformin combined ( P < 0.05 vs. all other conditions: metformin/sedentary: 12 ± 3.4, metformin/exercise: 9.7 ± 2.3, washout/sedentary: 13.3 ± 3.2, washout/exercise: 11.1 ± 3.4 mmol/l). Postmeal exercise and metformin in combination resulted in the lowest peak postprandial glucose excursion compared with either treatment modality alone. Exercise timed to the postprandial phase may be important for optimizing glucose control during metformin monotherapy. NEW & NOTEWORTHY The interactive effects of metformin and exercise on key physiological outcomes remain an area of controversy. Findings from this study show that the combination of

    Purpose To assess the efficacy and safety of switching from prostaglandin analog (PGA) monotherapy to tafluprost/timolol fixed-combination (Taf/Tim) therapy. Subjects and Methods Patients with primary open-angle glaucoma, normal-tension glaucoma, or ocular hypertension who had received PGA monotherapy for at least 3 months were enrolled. Patients were examined at 1, 2, and 3 months after changing therapies. Subsequently, the patients were returned to PGA monotherapy. The examined parameters included intraocular pressure (IOP) and adverse events. A questionnaire survey was conducted after the switch to Taf/Tim therapy. Results Forty patients with a mean age of 66.5 ± 10.3 years were enrolled; 39 of these patients completed the study protocol. Switching to Taf/Tim significantly reduced the IOP from 18.2 ± 2.6 mmHg at baseline to 14.8 ± 2.5 mmHg at 1 month, 15.2 ± 2.8 mmHg at 2 months, and 14.9 ± 2.5 mmHg at 3 months (P < 0.001). Switching back to the original PGA monotherapy returned the IOP values to baseline levels. Taf/Tim reduced the pulse rate insignificantly. No significant differences were observed in blood pressure, conjunctival hyperemia, or corneal adverse events. A questionnaire showed that the introduction of Taf/Tim did not significantly influence symptoms. Conclusions Compared with PGA monotherapy, Taf/Tim fixed-combination therapy significantly reduced IOP without severe adverse events. PMID:29675274

    Antiepileptic drugs have been shown to be associated with a lowering of bone mineral density in childhood and adolescence, which are critical periods of skeletal mineralization. A lower peak bone mass attained at the end of adolescence is associated with greater involutional osteoporosis and risk for fracture in the elderly. Our purpose was to evaluate the effects of carbamazepine and valproate monotherapy on bone mineral density in children in Taiwan. From November 1995 to April 2005, forty-two children with uncomplicated epilepsy, who were treated with either carbamazepine (n=21) or valproate (n=21) monotherapy for more than 6 months, were enrolled in this study. All subjects were 5 to 18 years of age, seizure-free for 5 months or more, with normal daily activity, and normal diet. Lumbar bone mineral density of L1 to L4 was measured by dual-energy X-ray absorptiometry. The mean serum levels of carbamazepine and valproate were 5.12 +/- 2.15 mcg/ml and 49.61 +/- 20.84 mcg/ml, respectively. Treatment durations were 37.05 +/- 31.11 months and 22.86 +/- 18.84 months, respectively. The serum levels of calcium and phosphate in both groups were within therapeutic range. The serum level of alkaline phosphatase was significantly higher in the carbamazepine group (264.71 +/- 66.91, U/L) than in the valproate group (179.48 +/- 79.37, U/L). Three patients (140%) had bone mineral density Z-score of -2.0 or lower in the carbamazepine-treated group, but none in the valproate-treated group (p=0.232). Comparing the Z-score in carbamazapine- and valproate-monotherapy children, 7 (33%) had Z-score of -1.5 or lower in the carbamazepine-treated group, and none in the valporate-treated group had Z-score of -1.5 or lower (p=0.009). Four (57%) patients in the 7 carbamazepine-treated children with Z-score of -1.5 or lower had serum drug level lower than therapeutic range. Children receiving carbarmazepine monotherapy had increased frequency of lower bone density than children receiving

    The aim of this study was to assess the effects of oxcarbazepine (OXC) on cognition and psychosocial difficulties in patients with new-onset partial epilepsy. Cognitive and psychosocial assessments were performed before and after 6 to 12 months of OXC monotherapy in 52 drug-naive patients (25 women; mean age, 31.1 years; SD, 12.1 years). Cognitive functions were evaluated with well-structured and validated tools. Mood, psychological distress, subjective handicap, and quality of life were also evaluated. Differences between baseline and after-treatment evaluation were compared and adjusted for possible confounders such as age, sex, seizure control, duration of epilepsy, assessment interval, and epileptogenic region. Mean assessment interval was 231.8 (range, 182-348) days, and mean (SD) OXC dose at retest was 693.8 (208.9) mg. The OXC was found to have no significant adverse effect on cognition. Furthermore, OXC monotherapy was not found to affect psychosocial difficulties, including psychological distress and subjective handicap. The results suggest that OXC monotherapy could be used to treat newly diagnosed partial epilepsy without adversely affecting cognitive and psychosocial functions.

    Abstract We investigated the treatment effects of aripiprazole monotherapy in first-episode medication-naïve patients with major depressive disorder (MDD). The accompanying changes in the gray matter volume (GMV) were also explored. Fifteen patients completed the trial and received structural scans by 3-Tesla magnetic resonance imaging at baseline and partially responding state (sixth week). To account for the test–retest bias, 27 healthy controls were scanned twice within 6 weeks. We utilized optimized voxel-based morphometry with different comparisons between groups. The partially responding patients with MDD had greater GMV in left middle frontal gyrus and left superior parietal gyrus when compared with baseline. However, they had decreases in the GMV of right orbitofrontal gyrus and right inferior temporal gyrus after response. The partially responding patients with MDD still had residual GMV deficits in right superior frontal gyrus when compared with controls. However, the lack of second patient group without aripiprazole intervention would be a significant limitation to interpret the aripiprazole-specific effects on GMV. The changes in the GMV of fronto-parieto-temporal regions and residual GMV deficits in the superior frontal gyrus might represent “state-dependent brain changes” and “residual-deficit brain regions,” respectively, for aripiprzole monotherapy in MDD.

    In NSCLC, second-line chemotherapy using pemetrexed or docetaxel has limited efficacy and should be dedicated to selected groups of patients. Pemetrexed is an antifolate compound with the ability to inhibit enzymes (TS, DHFR and GARFT) involved in pyrimidine and purine synthesis. The objective of this study was to evaluate the association between polymorphisms of TS and MHFR genes and clinical outcomes in NSCLC patients treated with pemetrexed monotherapy. DNA was isolated from peripheral blood of 72 non-squamous NSCLC patients treated with pemetrexed. Using PCR and RFLP methods, the variable number of tandem repeats (VNTR), the G > C SNP in these repeats and insertion/deletion polymorphism of TS gene as well as 677C > T SNP in MTHFR gene were analyzed and correlated with disease control rate, progression-free survival and overall survival (OS) of NSCLC patients. Carriers of 2R/3R(G), 3R(C)/3R(G), 3R(G)/3R(G) genotypes showed significantly more frequent early progression than carriers of 2R/2R, 2R/3R(C), 3R(C)/3R(C) genotypes of TS gene (p < 0.05). Among carriers of triple 28 bp tandem repeats (3R) in TS gene and C/C genotype of MTHFR gene a significantly shorter OS was observed (HR = 3.07; p = 0.003). In multivariate analysis, significantly higher risk of death was observed in carriers of both 3R/3R genotype in TS and C/C genotype in 677C > T SNP in MTHFR (HR = 3.85; p < 0.005) as well as in patients with short duration of response to first-line chemotherapy (HR = 2.09; p < 0.005). Results of our study suggested that genetic factors may have a high predictive and prognostic value (even greater than clinical factors) for patients treated with pemetrexed monotherapy.

    This study investigated safety and effectiveness of olanzapine in monotherapy compared with conventional antipsychotics in treatment of acute inpatients with schizophrenia. This was a prospective, comparative, nonrandomized, open-label, multisite, observational study of Spanish inpatients with an acute episode of schizophrenia. Data included safety assessments with an extrapyramidal symptoms (EPS) questionnaire and the report of spontaneous adverse events, plus clinical assessments with the Brief Psychiatric Rating Scale (BPRS) and the Clinical Global Impressions-Severity of Illness (CGI-S). A multivariate methodology was used to more adequately determine which factors can influence safety and effectiveness of olanzapine in monotherapy. 339 patients treated with olanzapine in monotherapy (OGm) and 385 patients treated with conventional antipsychotics (CG) were included in the analysis. Treatment-emergent EPS were significantly higher in the CG (p<0.0001). Response rate was significantly higher in the OGm (p=0.005). Logistic regression analyses revealed that the only variable significantly correlated with treatment-emergent EPS and clinical response was treatment strategy, with patients in OGm having 1.5 times the probability of obtaining a clinical response and patients in CG having 5 times the risk of developing EPS. In this naturalistic study olanzapine in monotherapy was better-tolerated and at least as effective as conventional antipsychotics.

    First-line nurse managers in small rural hospitals are essential to organizational survival, yet little is known about such individuals. A pilot study comparing demographic characteristics and career success perceptions of first-line nurse managers from rural settings with doctorally prepared nurses found that despite age and educational differences, personal characteristics identified as contributing to career success were remarkably similar in both groups. First-line nurse managers generally credited family members with greater degrees of career influence than did their more educated colleagues. However, both groups saw themselves as primarily responsible for their own career success. This information may assist rural hospitals and nursing personnel to enhance their strategic position in the unstable environment of health care reform.

    Merkel cell carcinoma (MCC) is an aggressive skin cancer that is associated with poor survival outcomes in patients with distant metastatic disease. Results of part A of the JAVELIN Merkel 200 trial (avelumab in patients with Merkel cell carcinoma) showed that avelumab, an anti-programmed cell death ligand 1 (PD-L1) antibody, demonstrated efficacy in second-line or later treatment of patients with metastatic MCC (mMCC). To evaluate the efficacy and safety of avelumab as first-line treatment for patients with distant mMCC. JAVELIN Merkel 200 part B is an international, multicenter, single-arm, open-label clinical trial of first-line avelumab monotherapy. Eligible patients were adults with mMCC who had not received prior systemic treatment for metastatic disease. Patients were not selected for PD-L1 expression or Merkel cell polyomavirus status. Data were collected from April 15, 2016, to March 24, 2017, and enrollment is ongoing. Patients received avelumab, 10 mg/kg, by 1-hour intravenous infusion every 2 weeks until confirmed disease progression, unacceptable toxic effects, or withdrawal occurred. Tumor status was assessed every 6 weeks and evaluated by independent review committee per Response Evaluation Criteria in Solid Tumors version 1.1. The primary end point was durable response, defined as an objective response with a duration of at least 6 months. Secondary end points include best overall response, duration of response, progression-free survival, safety, and tolerability. As of March 24, 2017, 39 patients were enrolled (30 men and 9 women; median age, 75 years [range, 47-88 years]), with a median follow-up of 5.1 months (range, 0.3-11.3 months). In a preplanned analysis, efficacy was assessed in 29 patients with at least 3 months of follow-up; the confirmed objective response rate was 62.1% (95% CI, 42.3%-79.3%), with 14 of 18 responses (77.8%) ongoing at the time of analysis.

    Oxcarbazepine (OXC) is widely used in anti-epileptic treatment. Cytochrome P450 3A4 (CYP3A4), cytochrome P450 3A5(CYP3A5), and ATP-binding cassette sub-family B member 1 (ABCB1) are potential genes involved in OXC metabolisms and transport in vivo. This study aims to examine the genetic effects of CYP3A4, CYP3A5, and ABCB1 on OXC metabolism and transport in Chinese epileptic patients using OXC as monotherapy and bitherapy with lamotrigine (LTG), levetiracetam (LEV), or valproic acid (VPA). Sixty-six Chinese epileptic patients were recruited from Xiangya Hospital Central South University, of whom 40 patients were receiving OXC monotherapy, 11 patients were placed in the OXC bitherapy group combined with one enzyme-inducing anti-epileptic drugs (LTG or LEV), and 15 patients were placed in the OXC bitherapy group combined with VPA. Oxcarbazepine and its main metabolite 10-hydrocarbazepine (MHD) plasma concentrations were measured using high performance liquid chromatography (HPLC)-UV method. In addition, eight single nucleotide polymorphisms (SNPs) in CYP3A4, CYP3A5, ABCB1 gene were genotyped by polymerase chain reaction-improved multiple ligase detection reaction (PCR-iMLDR). In the OXC+VPA group, ABCB1 rs2032582 and rs2032582-rs10234411-rs1045642 TAG haplotype were associated with MHD and MHD+OXC plasma concentration before permutation test. In OXC monotherapy and OXC+ LTG/LEV groups, no significant association between genetic polymorphisms in CYP3A4/5, ABCB1 gene and OXC plasma concentration parameters were observed. CYP3A4/5 and ABCB1 genetic variants might not take part in the metabolism and transport of MHD and OXC among epileptic patients using OXC monotherapy and bitherapy in combination with LEV, LTG or VPA.

    Erlotinib is approved for the first line treatment of epidermal growth factor receptor (EGFR) mutation-positive non-small cell lung cancer. Since the number of prospective studies in Caucasian patients treated in routine clinical setting is limited we conducted a multicenter, phase IV clinical trial to determine the efficacy and safety of erlotinib and to demonstrate the feasibility of the validated standardized companion diagnostic method of EGFR mutation detection. 651 chemonaive, cytologically or histologically verified advanced stage lung adenocarcinoma patients from Hungary, Turkey and Latvia were screened for exon19 microdeletions and exon21 L858R EGFR mutations using the companion diagnostic EGFR test. EGFR mutation-positive, locally advanced or metastatic lung adenocarcinoma patients received as first line treatment erlotinib at 150 mg/day. The primary endpoint was progression-free survival (PFS). 62 EGFR mutation-positive patients (9.5% of screened) were included in the safety/intent-to-treat cohort. Median PFS was 12.8 months (95%CI, 9.9-15.8), objective response rate and one-year survival was 66.1% and 82.5%, respectively. Most frequent treatment related adverse events were diarrhoea and rash. Eastern Oncology Cooperative Group Performance Status (ECOG PS), smoking status and M1a/M1b disease stage were significant prognosticators of PFS (p = 0.017, p = 0.045 and p = 0.002, respectively). There was no significant difference in PFS between the subgroups stratified by gender, age or exon19 vs exon21 mutation. Our study confirmed the efficacy and safety of first line erlotinib monotherapy in Caucasian patients with locally advanced or metastatic lung adenocarcinoma carrying activating EGFR mutations based on the screening with the approved companion diagnostic procedure.

    2015-03-01

    The aim of this study was to explore how first-line nurse managers constructed the meaning of resilience and its relationship to work-life balance for nurses in Korea. Participants were 20 first-line nurse managers working in six university hospitals. Data were collected through in-depth interviews from December 2011 to August 2012, and analyzed using Strauss and Corbin's grounded theory method. Analysis revealed that participants perceived work-life balance and resilience to be shaped by dynamic, reflective processes. The features consisting resilience included "positive thinking", "flexibility", "assuming responsibility", and "separating work and life". This perception of resilience has the potential to facilitate a shift in focus from negative to positive experiences, from rigidity to flexibility, from task-centered to person-centered thinking, and from the organization to life. Recognizing the importance of work-life balance in producing and sustaining resilience in first-line nurse managers could increase retention in the Korean nursing workforce. Copyright © 2015.

    2012-01-01

    The efficacy and safety of the dipeptidyl peptidase-4 inhibitor, vildagliptin, as monotherapy have been widely confirmed in a large body of clinical studies of up to 2 years’ duration in various populations with type 2 diabetes mellitus. This paper reviews the data supporting the use of vildagliptin in monotherapy. Consideration based on baseline glycated hemoglobin levels and age is given to patient segments where metformin is not appropriate. In addition, although prediabetes is not an indication, this manuscript briefly reviews some of the existing data showing that the mechanisms at work in diabetic populations are active in patients currently classified as prediabetic, with impaired glucose tolerance or impaired fasting glucose. Finally, the rationale for vildagliptin dosing frequency in monotherapy is discussed. In summary, this review aims to define where in community practice the use of vildagliptin as monotherapy is most desirable, focusing on segments of the population with type 2 diabetes mellitus that might receive the greatest benefit from vildagliptin in the management of their disease.

    This study aims to evaluate the efficacy of Methotrexate (MTX) alone and combined therapy with Etanercept (ETN) and Methotrexate in patients with active rheumatoid arthritis (RA). In the randomised control study, conducted in the period from March 2014 until March 2016, we evaluated the efficacy of the treatment of patients with RA with MTX as monotherapy and combination treatment with MTX and ETN. In the Clinic of Rheumatology in Prishtina, 90 adult patients with RA were treated in combination with ETN (doses of 50 mg subcutaneously/weekly), with oral MTX (doses up to 20 mg weekly), and MTX alone (doses up to 20 mg weekly) during this period of two years. Clinical response was assessed using European League against Rheumatism (EULAR)/American College of Rheumatology (ACR) Criteria and the Disease Activity Score (DAS28). Radiographic changes were measured in the beginning and at the end of the study using Larsen's method. Of the cohort groups of 90 patients, mean age of 55.63, 15 patients, (16.6 %) were treated with combined therapy (ETN plus MTX) and 75 patients (83.3%) with monotherapy (MTX). After two years of treatment the group with combined therapy resulted with improvement of acute phase reactants as erythrocyte sedimentation rate (ESR) for the first hour (41.1 vs. 10.3 mm/hour) and C - reactive protein (CRP) (40.8 vs. 6 mg/liter), and compared to the group treated with monotherapy, there were no significant changes (ESR: 45.7 vs 34.3 mm/hour; CRP: 48 vs 24 mg/liter). Before the treatment, the severity of the disease was high, wherein the group with combined therapy DAS28 was 5.32, compared to the monotherapy group whom DAS28 was 5.90. After 2 years of treatment, we had significant changes in the results of DAS28, wherein the group treated with ETN plus MTX DAS28 was 2.12 ± 0.15, while in the group of patients treated with MTX DAS28 were 3.75 ± 0.39 (t = 13.03; df = 58; p < 0.0001).

    Abstract Background: Methotrexate (MTX) is widely used and considered a first-line disease modifying antirheumatic drug (DMARD) for the treatment of rheumatoid arthritis (RA). However, 10% to 30% of patients discontinue therapy within a year of starting the treatment, usually because of undesirable side effects. Many of the relevant genes have been investigated to estimate the association between gene polymorphisms and MTX toxicity in RA patients, although inconsistent results have been reported. Methods: We searched EMBASE and PubMed in February 2016 for polymorphisms and pharmacogenomics study of the toxicity of MTX monotherapy in RA patients. The meta-analysis was stratified by whether genetic variants associated with MTX toxicity. Results: A total of 42 publications that included 28 genes with 88 gene SNPs associated with the transporters, enzymes, and metabolites of MTX or the progression of RA were included in the SR, and 31 studies were included in 7 meta-analyses. The meta-analysis showed a significant association between the toxicity of MTX and the RFC-1 80G > A (rs1051266) polymorphism in the European RA patients. Conclusion: RFC-1 80G > A (rs1051266) polymorphism was associated with MTX toxicity, and larger and more stringent study designs may provide more accurate results for the effect of these SNPs on the MTX toxicity.

    Reporting a special clinical finding after intravitreal bevacizumab monotherapy for retinopathy of prematurity. In a retrospective case series, the clinical courses of five premature infants with similar vitreous changes after a single dose of intravitreal bevacizumab (IVB) injection without additional laser therapy were reported. The mean post-conceptional age at IVB injection was 39.8 ± 2.2 (range 37-43) weeks. Localized vitreous syneresis and linear fibrotic vitreous condensation occurred 8.2 ± 2.3 weeks after IVB monotherapy in our patients (15.5% of injections). The mean last post injection visit was 61.6 ± 5.3 weeks (post-conceptional age). Further regression and complete retinal vascularization occurred in all patients. Thread-like vitreous condensation with localized vitreous liquefaction may be related to involutional ROP disease itself, combined to anti VEGF therapy and may be a predictor factor for further regression and retinal vascularization. The case series describes a successful response to anti-VEGF monotherapy with no further complications.

    VIKING-4 assessed the safety and efficacy of dolutegravir in heavily antiretroviral treatment-experienced patients who had documented integrase strand transfer inhibitor (INSTI) resistance-associated substitutions in their HIV. VIKING-4 had a placebo-controlled 7-day dolutegravir functional monotherapy phase followed by dolutegravir plus an optimized background regimen for 48 weeks. Independent resistance analyses evaluated week 48 virological responses in the VIKING-4 trial based on the presence of baseline INSTI resistance-associated substitutions and baseline dolutegravir phenotypic susceptibility. Response rates at week 48 based on baseline dolutegravir resistance subgroups were compared for the 7-day dolutegravir functional monotherapy arm and placebo-control arm. Additionally, genotypic and phenotypic resistance at day 8 and time of failure was analysed for the virological failures from both arms. Week 48 response rates for VIKING-4 were 23% (3/13) in the 7-day dolutegravir functional monotherapy arm compared with 60% (9/15) in the 7-day placebo arm. Response rates were consistently lower in the dolutegravir functional monotherapy arm across baseline INSTI genotypic and phenotypic subgroups. There was a higher proportion of virological failures in the 7-day dolutegravir functional monotherapy arm (n=6/13; 46%) compared with the 7-day placebo arm (n=3/15; 20%). Additionally, five virological failures in the dolutegravir arm had virus expressing emergent INSTI resistance-associated substitutions compared with two in the placebo arm. Analysis of response rates and resistance emergence in VIKING-4 suggests careful consideration should be given to the duration of functional monotherapy in future studies of highly treatment-experienced patients to reduce the risk of resistance and virological failure.

    2017-09-01

    The use of noninvasive ventilation (NIV) in non-COPD patients with pneumonia is controversial due to its high rate of failure and the potentially harmful effects when NIV fails. The purpose of the study was to evaluate outcomes of the first ventilatory treatment applied, NIV or invasive mechanical ventilation (MV), and to identify predictors of NIV failure. Historical cohort study of 159 non-COPD patients with pneumonia admitted to the ICU with ventilatory support. Subjects were divided into 2 groups: invasive MV or NIV. Univariate and multivariate analyses with demographic and clinical data were performed. Analysis of mortality was adjusted for the propensity of receiving first-line invasive MV. One hundred and thirteen subjects received first-line invasive MV and 46 received first-line NIV, of which 27 needed intubation. Hospital mortality was 35, 37 and 56%, respectively, with no significant differences among groups. In the propensity-adjusted analysis (expressed as OR [95% CI]), hospital mortality was associated with age (1.05 [1.02-1.08]), SAPS3 (1.03 [1.00-1.07]), immunosuppression (2.52 [1.02-6.27]) and NIV failure compared to first-line invasive MV (4.3 [1.33-13.94]). Compared with invasive MV, NIV failure delayed intubation (p=.004), and prolonged the length of invasive MV (p=.007) and ICU stay (p=.001). NIV failure was associated with need for vasoactive drugs (OR 7.8 [95% CI, 1.8-33.2], p=.006). In non-COPD subjects with pneumonia, first-line NIV was not associated with better outcome compared with first-line invasive MV. NIV failure was associated with longer duration of MV and hospital stay, and with increased hospital mortality. The use of vasoactive drugs predicted NIV failure. Copyright © 2016 SEPAR.

    To compare the efficacy and safety of acarbose plus metformin fixed-dose combination (FDC) versus acarbose monotherapy for type 2 diabetes (T2D). Eligible T2D patients undergoing treatment with diet control only or oral antidiabetic medications were run-in on acarbose 50mg thrice-daily for 4 weeks, then randomised either to continue this monotherapy, or to acarbose 50mg plus metformin hydrochloride 500mg FDC (acarbose/metformin FDC), each thrice-daily for 16 weeks. Acarbose/metformin FDC therapy significantly reduced HbA1c, fasting plasma glucose (FPG), and postprandial plasma glucose (PPG) from baseline (all p<0.0001) with superior efficacy compared with acarbose monotherapy (between-group differences; HbA1c -1.35%; FPG -29.5mg/dl; PPG -41.6mg/dl; all p<0.0001). Proportionally more patients treated with acarbose/metformin FDC achieved HbA1c <7.0% (47.8% vs. 10.7%, p<0.0001). Both treatments reduced bodyweight (p<0.0001), with a significant between-group difference (-0.6kg, p<0.01) favouring acarbose/metformin FDC. Hypoglycaemia was not reported with either treatment, and the incidence of other adverse events did not differ significantly between the groups. Compared with acarbose monotherapy, acarbose/metformin FDC has superior antihyperglycaemic efficacy, brings proportionally more T2D patients to HbA1c goal, and further reduces bodyweight. Acarbose/metformin FDC is well-tolerated without significant risk of hypoglycaemia and is a potentially advantageous therapy for T2D. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    Mefloquine and artesunate combination therapy is the recommended first-line treatment for uncomplicated malaria throughout much of south-east Asia. Concerns have been raised about the potential central nervous system (CNS) effects of both drug components and there are no detailed reports in very young children. Children, aged between three months and five years, with acute uncomplicated Plasmodium falciparum malaria were randomized to either 7 days of artesunate monotherapy or the same schedule of artesunate plus mefloquine on day 7 and 8. Neurological testing targeting coordination and behaviour was carried out at day 0, 7, 9, 10, 14 and 28. Non-febrile healthy control children from the same population were tested on days 0, 7, 14 and 28. From December 1994 to July 1997, 91 children with uncomplicated P. falciparum, 45 treated with artesunate monotherapy, 46 treated with mefloquine and artesunate combination therapy and 36 non-febrile controls, underwent neurological testing. Malaria and fever had a significant negative impact on testing performance. By contrast, the anti-malarial treatments were not associated with worsening performances in the various components of the test. Artesunate and mefloquine do not appear to have a significant influence on coordination and behaviour. Children treated with mefloquine were significantly less likely to suffer recurrent malaria infection during follow-up compared to those treated with artesunate alone (P = 0.033). In keeping with the results of randomized controlled trials in adults, mefloquine was not associated with a decrease in specific items of neurological performance. Likewise, children treated with artesunate did not perform significantly differently to control children. This study does not exclude subtle or rare treatment CNS effects of artesunate or mefloquine. Treatment of acute uncomplicated malaria results in a significant improvement on items of neurological performance.

    The purpose of this study was to explore the budget impact of dutasteride plus tamsulosin fixed-dose combination (DUT + TAM FDC) versus tamsulosin monotherapy, in the treatment of patients with benign prostatic hyperplasia (BPH) from the perspective of the Greek healthcare insurance system. A Microsoft Excel-based model was developed to estimate the financial consequences of adopting DUT + TAM FDC within the Greek healthcare setting. The model, compared six mutually exclusive health states in two alternative treatment options: current standard of care and the introduction of DUT + TAM FDC in the market. The model used clinical inputs from the CombAT study; data on resource use associated with the management of BPH in Greece were derived from expert panel, and unit cost data were derived from official reimbursement tariffs. A payer perspective was taken into account. As patient distribution data between public and private sectors are not available in Greece two scenarios were investigated, considering the whole eligible population in each scenario. A 4 year time horizon was taken into account and included treatment costs, number of transurethral resections of the prostate (TURPs) and acute urinary retention (AUR) episodes avoided. The clinical benefit from the market adoption of DUT + TAM FDC in Greece was 1,758 TURPs and 972 episodes of AUR avoided cumulatively in a four year period. The increase in total costs from the gradual introduction of DUT + TAM FDC to the Greek healthcare system ranges from €1.3 million in the first year to €5.8 million in the fourth year, for the public sector, and €1.2 million to €4.0 million, for the private sector. This represents an increase of 1.91% to 7.94% for the public sector and 1.10% 3.29% in the private sector, during the 4-year time horizon. Budget impact analysis (BIA) results indicated that the gradual introduction of DUT + TAM FDC, would increase the overall budget of the disease, however providing

    Non-Hodgkin lymphoma (NHL) is the most common hematologic malignancy. The estimated deaths and new cases of NHL in the USA in 2018 have reached 19,910 and 74,680, respectively, with 5-year survival rate of 71%. Therapeutic interventions for NHL consist of chemotherapy, radiation therapy and immunotherapy. Radioimmunotherapy (RIT) is a potential alternative treatment for NHL that is currently used in different lines of treatment. Studies show that nuclear medicine physicians and radiation oncologists are not yet certain about the proper line for administration of RIT. Herein, we have reviewed the efficiency and toxicity of RIT as the first line of treatment, and discussed potential novel indications, and strategies such as modifying induction therapy and using rituximab maintenance to optimize the efficiency of RIT as the first line of treatment. Our review indicates that it is more logical to postpone conventional therapies to the second or third lines of treatment instead of RIT.

  11. Boosted protease inhibitor monotherapy in HIV-infected adults: outputs from a pan-European expert panel meeting

    2013-01-01

    While the introduction of combination highly active antiretroviral therapy (HAART) regimens represents an important advance in the management of human immunodeficiency virus (HIV)-infected patients, tolerability can be an issue and the use of several different agents may produce problems. The switch of combination HAART to ritonavir-boosted protease inhibitor (PI) monotherapy may offer the opportunity to maintain antiviral efficacy while reducing treatment complexity and the risks of toxicity. Current European AIDS Clinical Society (EACS) guidelines recognise ritonavir-boosted PI monotherapy with twice-daily lopinavir/ritonavir or once-daily darunavir/ritonavir as a possible option in patients who have intolerance to nucleoside reverse transcriptase inhibitors, or for treatment simplification. Clinical trials data for PI boosted monotherapy are encouraging, showing substantial efficacy in the majority of patients; however, further data are required before this approach can be recommended as a routine treatment. Available data indicate that the most suitable candidates for the use of boosted PI monotherapy are long-term virologically suppressed patients who have demonstrated good adherence to antiretroviral therapy, who do not have chronic hepatitis B, have no history of treatment failure on PIs and are able to tolerate low-dose ritonavir.

    To evaluate the longterm safety and efficacy of subcutaneous tocilizumab (TCZ-SC) as monotherapy in patients with rheumatoid arthritis (RA). Of 346 patients who received 24 weeks of double-blind treatment with either TCZ-SC monotherapy, 162 mg every 2 weeks (q2w); or intravenous TCZ (TCZ-IV) monotherapy, 8 mg/kg every 4 weeks; 319 patients continued to receive TCZ-SC q2w in the 84-week open-label extension (OLE) of the MUSASHI study (JAPICCTI-101117). Efficacy, safety, and immunogenicity were evaluated for all patients treated with TCZ during 108 weeks. The proportions of patients who achieved American College of Rheumatology 20/50/70 responses, low disease activity [28-joint Disease Activity Score (DAS28) ≤ 3.2], or remission (DAS28 < 2.6) at Week 24 were maintained until Week 108. The incidences of adverse events and serious adverse events were 498.3 and 16.9 per 100 patient-years (PY), respectively. The overall safety of TCZ-SC monotherapy was similar to that of TCZ-IV monotherapy. Rates of injection site reactions (ISR) through 108 weeks remained similar to rates through 24 weeks. ISR were mild and did not cause any patient withdrawals. No serious hypersensitivity events (including anaphylactic reactions) occurred. Anti-TCZ antibodies were present in 2.1% of patients treated with TCZ-SC monotherapy. TCZ-SC monotherapy maintained a favorable safety profile and consistent efficacy throughout the 108-week study. Like TCZ-IV, TCZ-SC could provide an additional treatment option for patients with RA.

    To determine the optimal approach to first-line treatment for low-risk gestational trophoblastic neoplasia (GTN) using a cost analysis of 3 commonly used regimens. A decision tree of the 3 most commonly used first-line low-risk GTN treatment strategies was created, accounting for toxicities, response rates and need for second- or third-line therapy. These strategies included 8-day methotrexate (MTX)/folinic acid, weekly MTX, and pulsed actinomycin-D (act-D). Response rates, average number of cycles needed for remission, and toxicities were determined by review of the literature. Costs of each strategy were examined from a societal perspective, including the direct total treatment costs as well as the indirect lost labor production costs from work absences. Sensitivity analysis on these costs was performed using both deterministic and probabilistic cost-minimization models with the aid of decision tree software (TreeAge Pro 2011, TreeAge Inc., Williamstown, Massachusetts). We found that 8-day MTX/folinic acid is the least expensive to society, followed by pulsed act-D ($4,867 vs. $6,111 average societal cost per cure, respectively), with act-D becoming more favorable only with act-D per-cycle cost <$231, or response rate to first-line therapy > 99%. Weekly MTX is the most expensive first-line treatment strategy to society ($9,089 average cost per cure), despite being least expensive to administer per cycle, based on lower first-line response rate. Absolute societal cost of each strategy is driven by the probability of needing expensive third-line multiagent chemotherapy, however relative cost differences are robust to sensitivity analysis over the reported range of cycle number and response rate for all therapies. Based on similar efficacy and lower societal cost, we recommend 8-day MTX/folinic acid for first-line treatment of low-risk GTN.

    In this work, we report first-principle theoretical predictions of methane spectral line intensities that are competitive with (and complementary to) the best laboratory measurements. A detailed comparison with the most accurate data shows that discrepancies in integrated polyad intensities are in the range of 0.4%-2.3%. This corresponds to estimations of the best available accuracy in laboratory Fourier Transform spectra measurements for this quantity. For relatively isolated strong lines the individual intensity deviations are in the same range. A comparison with the most precise laser measurements of the multiplet intensities in the 2ν3 band gives an agreement within the experimental error margins (about 1%). This is achieved for the first time for five-atomic molecules. In the Supplementary Material we provide the lists of theoretical intensities at 269 K for over 5000 strongest transitions in the range below 6166 cm-1. The advantage of the described method is that this offers a possibility to generate fully assigned exhaustive line lists at various temperature conditions. Extensive calculations up to 12,000 cm-1 including high-T predictions will be made freely available through the TheoReTS information system (http://theorets.univ-reims.fr, http://theorets.tsu.ru) that contains ab initio born line lists and provides a user-friendly graphical interface for a fast simulation of the absorption cross-sections and radiance.

    Alemtuzumab is increasingly being used as induction therapy for kidney transplantation, allowing immunosuppression minimization. This study examined the efficacy of alemtuzumab induction followed by low-dose tacrolimus monotherapy in standard risk primary kidney transplant patients. This retrospective cohort of primary standard risk renal transplant recipients were given alemtuzumab induction and low-dose tacrolimus maintenance immunosuppression (target trough 7 to 10 ng/mL for the first 6 months and 5 to 7 ng/mL thereafter). Serum creatinine values, acute rejection episodes, and graft survival were noted at week 1 as well as months 3, 6, 12, and 18. At the time of analysis, 47 patients were at 6 months, 28 at 12 months, and 6 patients at 18 months from transplant. Mean follow-up was 12.53 months (range, 6 to 23). Mean serum creatinine was 1.47 +/- 0.65 mg/dL at 3 months, 1.56 +/- 0.84 at 6 months, 1.45 +/- 0.37 at 12 months, and 1.74 +/- 0.35 at 18 months. The 1-year clinical acute rejection rate was 21% (6/28), occurring at 0 to 3 months in 2 (33%), 4 to 6 months in 1 (17%), and >6 months in 3 patients (50%). Biopsy-proven acute rejection was 14% (4/28). The episodes were classified as borderline in one, Banff 2A in two, and Banff 3 in one patients. One patient had both acute cellular and acute humoral rejection; half responded to steroid pulse therapy. The 1-year patient survival rate was 90%. The 1-year death-censored graft survival rate was 98%. Alemtuzumab induction with tacrolimus monotherapy is an acceptable option in standard risk patients. BPAR was 14%, but renal function remained satisfactory at 18 months posttransplant.

    Monotherapy has tended to replace the combination therapy in emprical treatment of febrile neutropenia. There is no reported trial which compares the efficacy of cefoperazone-sulbactam (CS) and piperacillin-tazobactam (PIP/TAZO) monotherapies in the treatment of febrile neutropenia. In this prospective randomized study, we aimed to compare the safety and efficacy of CS versus PIP/TAZO as empirical monotherapies in febrile neutropenic children with cancer. The study included febrile, neutropenic children hospitalized at our center for cancer. They were randomly selected to receive CS 100 mg/kg/day or PIP/TAZO 360 mg/kg/day. Duration of fever and neutropenia, absolute neutrophil count, modification, and success rate were compared between the two groups. Resolution of fever without antibiotic change was defined as success and resolution of fever with antibiotic change or death of a patient was defined as failure. Modification was defined as changing the empirical antimicrobial agent during a febrile episode. One hundred and two febrile neutropenic episodes were documented in 55 patients with a median age of 4 years. In 50 episodes CS and in 52 episodes PIP/TAZO was used. Duration of fever and neutropenia, neutrophil count, age, sex, and primary disease were not different between two groups. Success rates in the CS and PIP/TAZO groups were respectively 56 and 62% (P > 0.05). Modification rate between two groups showed no significant difference (P > 0.05). No serious adverse effect occurred in either of the groups. CS and PIP/TAZO monotherapy are both safe and effective in the initial treatment of febrile neutropenia in children with cancer.

    AIM: This study aims to evaluate the efficacy of Methotrexate (MTX) alone and combined therapy with Etanercept (ETN) and Methotrexate in patients with active rheumatoid arthritis (RA). METHODS: In the randomised control study, conducted in the period from March 2014 until March 2016, we evaluated the efficacy of the treatment of patients with RA with MTX as monotherapy and combination treatment with MTX and ETN. In the Clinic of Rheumatology in Prishtina, 90 adult patients with RA were treated in combination with ETN (doses of 50 mg subcutaneously/weekly), with oral MTX (doses up to 20 mg weekly), and MTX alone (doses up to 20 mg weekly) during this period of two years. Clinical response was assessed using European League against Rheumatism (EULAR)/American College of Rheumatology (ACR) Criteria and the Disease Activity Score (DAS28). Radiographic changes were measured in the beginning and at the end of the study using Larsen’s method. RESULTS: Of the cohort groups of 90 patients, mean age of 55.63, 15 patients, (16.6 %) were treated with combined therapy (ETN plus MTX) and 75 patients (83.3%) with monotherapy (MTX). After two years of treatment the group with combined therapy resulted with improvement of acute phase reactants as erythrocyte sedimentation rate (ESR) for the first hour (41.1 vs. 10.3 mm/hour) and C - reactive protein (CRP) (40.8 vs. 6 mg/liter), and compared to the group treated with monotherapy, there were no significant changes (ESR: 45.7 vs 34.3 mm/hour; CRP: 48 vs 24 mg/liter). Before the treatment, the severity of the disease was high, wherein the group with combined therapy DAS28 was 5.32, compared to the monotherapy group whom DAS28 was 5.90. After 2 years of treatment, we had significant changes in the results of DAS28, wherein the group treated with ETN plus MTX DAS28 was 2.12 ± 0.15, while in the group of patients treated with MTX DAS28 were 3.75 ± 0.39 (t = 13.03; df = 58; p < 0.0001). The group with combined therapy showed no

    Most high-grade serous ovarian carcinoma (HGSOC) patients benefit from first-line platinum-based chemotherapy, but progressively develop resistance during subsequent lines. Re-activating BRCA1 or MDR1 mutations can underlie platinum resistance in end-stage patients. However, little is known about resistance mechanisms occurring after a single line of platinum, when patients still qualify for other treatments. In 31 patients with primary platinum-sensitive HGSOC, we profiled tumours collected during debulking surgery before and after first-line chemotherapy using whole-exome sequencing and single nucleotide polymorphism profiling. Besides germline BRCA1/2 mutations, we observed frequent loss-of-heterozygosity in homologous recombination (HR) genes and mutation spectra characteristic of HR-deficiency in all tumours. At relapse, tumours differed considerably from their primary counterparts. There was, however, no evidence of events reactivating the HR pathway, also not in tumours resistant to second-line platinum. Instead, a platinum score of 13 copy number regions, among other genes including MECOM, CCNE1 and ERBB2, correlated with platinum-free interval (PFI) after first-line therapy, whereas an increase of this score in recurrent tumours predicted the change in PFI during subsequent therapy. Already after a single line of platinum, there is huge variability between primary and recurrent tumours, advocating that in HGSOC biopsies need to be collected at relapse to tailor treatment options to the underlying genetic profile. Nevertheless, all primary platinum-sensitive HGSOCs remained HR-deficient, irrespective of whether they became resistant to second-line platinum, further suggesting these tumours qualify for second-line Poly APD ribose polymerase (PARP) inhibitor treatment. Finally, chromosomal instability contributes to acquired resistance after a single line of platinum therapy. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Hypertension is known to be one of the main risk factors for cardiovascular disease. To evaluate the safety and efficacy of a fixed olmesartan/amlodipine (Olme/Amlo) combination in improving blood pressure control, lipid profile, insulin sensitivity and some inflammatory and insulin resistance markers. Two hundred and seventy-six hypertensive patients were randomly assigned to olmesartan 20 mg, amlodipine 10 mg or a single pill containing an Olme/Amlo combination 20/5 mg for 12 months. We evaluated after 6 and 12 months: body weight, body mass index (BMI), systolic and diastolic blood pressure (SBP and DBP, respectively), fasting plasma glucose (FPG), fasting plasma insulin (FPI), lipid profile, vaspin, visfatin, interleukins 8 and 10 (IL-8 and IL-10, respectively). Patients also underwent an euglycemic, hyperinsulinemic clamp. Olme/Amlo combination was more effective in decreasing SBP, and DPB compared to single monotherapies after 12 months. Olme/Amlo combination, but not amlodipine, decreased FPG after 12 months. FPI and HOMA index were decreased, and M value increased by Olme/Amlo combination compared to olmesartan monotherapy, and to amlodipine monotherapy. Olme/Amlo significantly decreased IL-8 and IL-10 better than each monotherapy. Olme/Amlo single pill combination can be a safe and effective option to reduce blood pressure, improve insulin sensitivity and decrease inflammatory markers.

    To explore the first-line leaders' role in quality work in long-term care in Norway, in order to determine how that work is related to such success characteristics as leadership, staff, patients, performance, information and information technology. Cross-sectional telephone survey. The text was analysed using content analysis. Thirty-two Norwegian municipalities stratified according to region and population size. Sixty-four first-line leaders in nursing homes and home-based care. Main outcome measure The clinical microsystem approach is used as a framework by defining and designing measureable variables. Thirty-six leaders described how they initiated and motivated employees to be active in quality work; the remaining leaders indicated that they played a passive role. The first-line leaders played a key role in implementing national quality policies and regulations. The quantity of other success characteristics was low. The municipalities delegated the responsibility of implanting national policies to the first-line leaders. Missing were key quality success criteria such as macro- and meso-perspectives for the municipality as a whole and co-operation with other leaders in the organization and fostering of relevant learning. Quality work was fragmented rather than comprehensive and systematic.

    The objective of these studies was to investigate whether a skincare product containing Ambophenol, Neurosensine, and La Roche-Posay thermal spring water formulated in a highly protective packaging can have an impact in the management of rosacea-prone skin subjects. Several studies were performed to evaluate the efficacy of this product in the management of rosacea prone skin, as either monotherapy or adjunctive therapy or to maintain the efficacy of a Metronidazole treatment. The first study was performed on 37 women aged 18-45 with added stage 2 erythro-couperosis, who applied test formula as monotherapy twice a day for 4 weeks. During a second study, a dermatological evaluation was performed on patients with stage I or II rosacea, a questionnaire containing information about patient characteristics, tolerance, clinical signs, symptoms and skin reactivity to "trigger factors" was completed by dermatologists at baseline and 2 months after treatment with the test formula as either monotherapy or adjunctive therapy. Finally, in a third study, 65 patients finishing a Metronidazole treatment applied once daily and the tested formula twice daily were divided into 2 groups using the test formula or vehicle control, twice a day for 8 weeks for the evaluation of efficacy as adjunctive therapy. We noted that the test formula, as an adjunctive therapy, helped prolong the efficacy of a Metronidazole treatment. In monotherapy, there was a significant efficacy of the test formula associated with an excellent tolerance. A significant improvement of all the clinical signs and symptoms of rosacea and a reduction of the skin reactivity to "trigger factors" were shown. These studies highlight the interest value and impact of a skincare product containing Ambophenol, Neurosensine, and La Roche-Posay thermal spring water formulated in a highly protective packaging in monotherapy or in combination with or after a therapeutic treatment in the management of patients suffering from

    This study, for the first time, investigated lithium monotherapy associated effects on amygdala- ventromedial prefrontal cortex (vMPFC) resting-state functional connectivity and correlation with clinical improvement in bipolar disorder (BP) METHODS: Thirty-six medication-free subjects - 24 BP (12 hypomanic BPM) and 12 depressed (BPD)) and 12 closely matched healthy controls (HC), were included. BP subjects were treated with lithium and scanned at baseline, after 2 weeks and 8 weeks. HC were scanned at same time points but were not treated. The effect of lithium was studied for the BP group as a whole using two way (group, time) ANOVA while regressing out effects of state. Next, correlation between changes in amygdala-vMPFC resting-state connectivity and clinical global impression (CGI) of severity and improvement scale scores for overall BP illness was calculated. An exploratory analysis was also conducted for the BPD and BPM subgroups separately. Group by time interaction revealed that lithium monotherapy in patients was associated with increase in amygdala-medial OFC connectivity after 8 weeks of treatment (p = 0.05 (cluster-wise corrected)) compared to repeat testing in healthy controls. Increased amygdala-vMPFC connectivity correlated with clinical improvement at week 2 and week 8 as measured with the CGI-I scale. The results pertain to open-label treatment and do not account for non-treatment related improvement effects. Only functional connectivity was measured which does not give information regarding one regions effect on the other. Lithium monotherapy in BP is associated with modulation of amygdala-vMPFC connectivity which correlates with state-independent global clinical improvement. Copyright © 2017.

    To assess the efficacy and safety of eslicarbazepine acetate (ESL) monotherapy. This post hoc pooled analysis of 2 randomized double-blind studies (093-045 and -046) included adults with partial-onset seizures medically uncontrolled by 1 or 2 antiepileptic drugs (AEDs). Following the baseline period (8 weeks), eligible patients were randomized 2:1 to receive ESL 1,600 mg or 1,200 mg once daily for 18 weeks; the primary endpoint was study exit by meeting predefined exit criteria (signifying worsening seizure control). In each study, treatment was considered effective if the upper 95% confidence limit for exit rate was lower than the historical control threshold (65.3%). Pooled exit rates were as follows: ESL 1,600 mg = 20.6% (95% confidence interval: 15.6%-26.8%); ESL 1,200 mg = 30.8% (23.0%-40.5%). Use of 2 baseline AEDs or rescue medication, US location, epilepsy duration ≥20 years, and higher maximum baseline seizure frequency were associated with higher exit risks. Median percent reductions in standardized seizure frequency between baseline and the 18-week double-blind period were as follows: ESL 1,600 mg = 43.2%; ESL 1,200 mg = 35.7%; baseline carbamazepine use was associated with smaller reductions. Safety profiles were similar between ESL doses. Exit rates for ESL monotherapy (1,600 mg and 1,200 mg once daily) were lower than the historical control threshold, irrespective of baseline AED use and region, with no additional safety concerns identified. Clinical factors and location clearly influence treatment responses in conversion-to-monotherapy trials. This pooled analysis provides Class IV evidence that for adults with medically uncontrolled partial-onset seizures, ESL monotherapy is well tolerated and effective. © 2016 American Academy of Neurology.

    This retrospective chart review study was conducted to evaluate the efficacy of estramustine phosphate sodium hydrate (EMP) monotherapy in patients with castration-resistant prostate cancer (CRPC) and to determine who would benefit from EMP therapy. EMP was administered at a daily dose of 560 mg to 102 patients as a third-line therapy, who had already received combined androgen blockade (CAB) and subsequent alternative antiandrogen therapy. The responses to EMP after its induction and its toxicity were evaluated. We also analyzed the association between the clinicopathological factors of the patients and their responses to EMP therapy. A reduction in the serum prostate-specific antigen (PSA) 4 weeks after induction was observed in 70 patients (68.6%), while 30 cases (29.4%) achieved more than 50% reduction of PSA. Long-term reduction of PSA from baseline for more than 6 months was observed in 31 patients (30.4%). EMP treatment was discontinued in 11 patients (10.8%) because of side effects (nausea in six patients, gynecomastia in three patients, eruption in one patient, and liver dysfunction in one patient). Multivariate analysis demonstrated that long duration of prior hormonal therapy was an independent favorable factor for reduced PSA levels, long responses, and overall survival. The data suggest that oral EMP administration as a third-line monotherapy is well tolerated and effective to some degree in patients with CRPC who have already received CAB and subsequent alternative antiandrogen therapy. Thus, EMP can be regarded as one treatment option, especially for patients whose prior duration of hormonal therapy was long.

Patients completing or exiting SP902 with LCM as monotherapy or as adjunctive therapy were eligible to enter this 2-year open-label extension (OLE) trial (SP904; NCT00530855) at a starting dose ±100 mg/day of their final SP902 dose. Investigators could adjust the LCM dose to 100-800 mg/day and add up to two antiepileptic drugs to optimize tolerability and seizure reduction. Three hundred twenty-two patients received LCM: 210 patients (65.2%) completed and 112 (34.8%) discontinued, most commonly owing to withdrawal of consent (9.3%). Two hundred fifty-eight patients (80.1%) had ≥1 year of and 216 (67.1%) had ≥2 years of LCM exposure, of whom 179/258 (69.4%) achieved LCM monotherapy lasting for any 12-month period, and 126/216 (58.3%) patients exposed for ≥24 months achieved LCM monotherapy for any 24-month period. Total exposure = 525.5 patient-years. The median modal dose was 500 mg/day. Two hundred ninety-two patients (90.7%) achieved LCM monotherapy at some point during the study. Sixty-five of 87 patients who exited and 193/235 who completed SP902 were exposed for ≥12 months, and 43.1% and 78.2%, respectively, achieved LCM monotherapy for ≥12 months. Median LCM monotherapy duration was 587.0 days (2-791 days); 91.0% of patients reported treatment-emergent adverse events, of which the most common were dizziness (27.3%), headache (17.1%), and nausea (14.3%). Compared with the SP902 study baseline, 74.2% of patients had a ≥50% seizure reduction and 5.6% were seizure-free at 24 months. The majority of patients were receiving LCM monotherapy at 0, 12, and 24 months in this OLE. Lacosamide monotherapy (median dose of 500 mg/day) had a safety profile similar to that of adjunctive therapy studies. These results support the use of

    To determine the factors contributing to managerial competence of first-line nurse managers. Understanding factors affecting managerial competence of nurse managers remains important to increase the performance of organizations; however, there is sparse research examining factors that influence managerial competence of first-line nurse managers. Systematic review. The search strategy was conducted from April to July 2017 that included 6 electronic databases: Science Direct, PROQUEST Dissertations and Theses, MEDLINE, CINAHL, EMBASE, and Google Scholar for the years 2000 to 2017 with full text in English. Quantitative and qualitative research papers that examined relationships among managerial competence and antecedent factors were included. Quality assessment, data extractions, and analysis were completed on all included studies. Content analysis was used to categorize factors into themes. Eighteen influencing factors were examined and categorized into 3 themes-organizational factors, characteristics and personality traits of individual managers, and role factors. Findings suggest that managerial competence of first-line nurse managers is multifactorial. Further research is needed to develop strategies to develop managerial competence of first-line nurse managers. © 2017 John Wiley & Sons Australia, Ltd.

    Abatacept (ABA) has recently been proposed as second-line treatment in patients with juvenile idiopathic arthritis (JIA)-associated uveitis refractory to anti-tumor necrosis factor-α (anti-TNF) agents, but little is known about its efficacy as a first-line approach. The aim of the present study was to compare the safety and efficacy of ABA as a first-line biological agent (ABA-1) with that of ABA as a second-line treatment after 1 or more anti-TNF agents (ABA-2), in patients with severe JIA-related uveitis. In this multicenter study, we collected data on patients with severe JIA-related uveitis treated with ABA as a first-line or second-line biological agent. Changes in frequency of uveitis flares/year and ocular complications before and after ABA treatment, clinical remission, and side effects were recorded. Thirty-five patients with a mean age of 10.8 years were treated with ABA for a mean period of 19.6 months. In 4 patients, ABA administration was discontinued, owing to inefficacy on arthritis in 3 cases and allergic reaction in 1. Thirty-one patients, 14 in the ABA-1 group and 17 in the ABA-2 group, completed the 12-month followup period; of these, 17 (54.8%) had clinical remission. The mean frequency of uveitis flares decreased from 4.1 to 1.2 in the ABA-1 group (p = 0.002) and from 3.7 to 1.2 in the ABA-2 group (p = 0.004). Preexisting ocular complications improved or remained stable in all but 5 patients, all in the ABA-2 group. No significant difference was found between the efficacy of the 2 treatment modalities. ABA confirmed its good safety profile. ABA, used as first-line biological treatment or after 1 or more anti-TNF agents, induces a comparable improvement in severe refractory JIA-related uveitis.

Medical charts of community-based patients who received EVE or FUL for mBC after NSAI were examined. Progression-free survival (PFS), time on treatment and time to chemotherapy were compared using Kaplan-Meier curves and Cox proportional hazards models adjusting for line of therapy and patient characteristics. 192 patients received EVE and 156 FUL. After adjusting for patient characteristics, EVE was associated with significantly longer PFS than FUL (hazard ratio: 0.71; p = 0.045). EVE was associated with better PFS than FUL among NSAI-refractory postmenopausal HR(+)/HER2(-) mBC patients.

    Worldwide, phenytoin and valproate are commonly used antiepileptic drugs. It is generally believed that phenytoin is more effective for partial onset seizures, and that valproate is more effective for generalised onset tonic-clonic seizures (with or without other generalised seizure types). This review is one in a series of Cochrane reviews investigating pair-wise monotherapy comparisons. This is the latest updated version of the review first published in 2001 and updated in 2013. To review the time to withdrawal, remission and first seizure of phenytoin compared to valproate when used as monotherapy in people with partial onset seizures or generalised tonic-clonic seizures (with or without other generalised seizure types). We searched the Cochrane Epilepsy Group's Specialised Register (19 May 2015), the Cochrane Central Register of Controlled Trials (CENTRAL; the Cochrane Library; 2015, Issue 4), MEDLINE (1946 to 19 May 2015), SCOPUS (19 February 2013), ClinicalTrials.gov (19 May 2015), and WHO International Clinical Trials Registry Platform ICTRP (19 May 2015). We handsearched relevant journals, contacted pharmaceutical companies, original trial investigators and experts in the field. Randomised controlled trials (RCTs) in children or adults with partial onset seizures or generalised onset tonic-clonic seizures with a comparison of valproate monotherapy versus phenytoin monotherapy. This was an individual participant data (IPD) review. Outcomes were time to: (a) withdrawal of allocated treatment (retention time); (b) achieve 12-month remission (seizure-free period); (c) achieve six-month remission (seizure-free period); and (d) first seizure (post-randomisation). We used Cox proportional hazards regression models to obtain study-specific estimates of hazard ratios (HRs) with 95% confidence intervals (CIs), and the generic inverse variance method to obtain the overall pooled HR and 95% CI. IPD were available for 669 individuals out of 1119 eligible individuals

  12. Allergic Reaction to Ketamine as Monotherapy for Procedural Sedation.

    Ketamine is a cyclohexamine derivative that acts as a noncompetitive N-methyl D-aspartate receptor antagonist. Its use for procedural sedation is recommended by national clinical policy. However, its immunogenic potential is not well documented. We report a case of allergic reaction associated with the administration of intravenous ketamine for procedural sedation in a 16-year-old male. Minutes after administration, the patient developed a morbilliform, erythematous rash that extended to the upper and lower torso and resolved with intravenous diphenhydramine. It is most likely that this allergic reaction was caused by a ketamine-induced histamine release that has been described in vitro. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This is the first case report in which ketamine was used as monotherapy in the emergency department for the facilitation of procedural sedation that resulted in an allergic reaction. Supportive measures, including advanced airway procedures and hemodynamic support, may be necessary in more severe anaphylactic cases. Providers should be aware of this potential adverse effect when using ketamine for procedural sedation. Copyright © 2016 Elsevier Inc. All rights reserved.

    Cerebrospinal fluid (CSF) viral escape is a concern in ritonavir-boosted protease inhibitors monotherapy. The aim was to assess HIV-RNA, biomarkers of immune activation and neurodegeneration, and atazanavir concentrations in CSF of patients on successful long-term atazanavir/ritonavir (ATV/r) monotherapy. This is a substudy of the multicentric, randomized, open-label, noninferiority trial monotherapy once a day with atazanavir/ritonavir (NCT01511809), comparing the ongoing ATV/r along with 2 nucleoside retrotranscriptase inhibitors (NRTIs) regimen to a simplified ATV/r monotherapy. Patients with plasma HIV-RNA < 50 copies/mL after at least 96 study weeks were eligible.We assessed HIV-RNA, soluble (s)CD14, sCD163, CCL2, CXCL10, interleukin-6, and YKL40 by enzyme-linked immunosorbent assay; neopterin, tryptophan, kynurenine, and neurofilament by immunoassays; and ATV concentrations by liquid chromatography-mass spectrometry in paired plasma and CSF samples. Variables were compared with Wilcoxon rank-sum or Fisher exact test, as appropriate. HIV-RNA was detected in the CSF of 1/11 patients on ATV/r monotherapy (114 copies/mL), without neurological symptoms, who was successfully reintensified with his previous 2NRTIs, and in none of the 12 patients on ATV/r + 2NRTIs. CSF biomarkers and ATV concentrations did not differ between the 2 arms. CSF escape was uncommon in patients on long-term ATV/r monotherapy and was controlled with reintensification.

  15. Identification of Mutation Accumulation as Resistance Mechanism Emerging in First-Line Osimertinib Treatment.

    The survival of patients with EGFR mutation-positive lung cancer has dramatically improved since the introduction of EGFR tyrosine kinase inhibitors (EGFR-TKIs). Recently, osimertinib showed significantly prolonged progression-free survival than first-generation EGFR-TKI in first-line treatment, suggesting that a paradigm change that would move osimetinib to first-line treatment is indicated. We performed N-ethyl-N-nitrosourea (ENU) mutagenesis screening to uncover the resistant mechanism in first- and second-line osimertinib treatment. Ba/F3 cells harboring EGFR activating-mutation with or without secondary resistant mutation were exposed to ENU for 24 hours to introduce random mutations and selected with gefitinib, afatinib, or osimertinib. Mutations of emerging resistant cells were assessed. The resistance of T790M and C797S to gefitinib and osimertinib, respectively, was prevalent in the mutagenesis screening with the Ba/F3 cells harboring activating-mutation alone. From C797S/activating-mutation expressing Ba/F3, the additional T790M was a major resistant mechanism in gefitinib and afatinib selection and the additional T854A and L792H were minor resistance mechanisms only in afatinib selection. However, the additional T854A or L792H mediated resistance to all classes of EGFR-TKI. Surprisingly, no resistant clone due to secondary mutation emerged from activating-mutation alone in the gefitinib + osimertinib selection. We showed the resistance mechanism to EGFR-TKI focusing on first- and second-line osimertinib using ENU mutagenesis screening. Additional T854A and L792H on C797S/activating-mutation were found as afatinib resistance and not as gefitinib resistance. Thus, compared to afatinib, the first-generation EGFR-TKI might be preferable as second-line treatment to C797S/activating-mutation emerging after first-line osimertinib treatment.

    We compared latanoprost monotherapy therapy with timolol/ dorzolamide in patients with primary open-angle glaucoma to evaluate the effects on intraocular pressure (IOP) and occurrence of adverse events. IOP and topical side effects were evaluated at the beginning, first, and third months. Mean IOP was decreased at the third month. The most common side effect was hyperemia (43.6%). We concluded that latanoprost reduces IOP better than fixed combination and its topical side effects are tolerable.

    The aim of this study was to investigate first-line nursing home managers' views on their leadership and related to that, palliative care. Previous research reveals insufficient palliation, and a number of barriers towards implementation of palliative care in nursing homes. Among those barriers are issues related to leadership quality. First-line managers play a pivotal role, as they influence working conditions and quality of care. Nine first-line managers, from different nursing homes in Sweden participated in the study. Semi-structured interviews were conducted and analysed using qualitative descriptive content analysis. In the results, two categories were identified: embracing the role of leader and being a victim of circumstances, illuminating how the first-line managers handle expectations and challenges linked to the leadership role and responsibility for palliative care. The results reveal views corresponding to committed leaders, acting upon demands and expectations, but also to leaders appearing to have resigned from the leadership role, and who express powerlessness with little possibility to influence care. The first line managers reported their own limited knowledge about palliative care to limit their possibilities of taking full leadership responsibility for implementing palliative care principles in their nursing homes. The study stresses that for the provision of high quality palliative care in nursing homes, first-line managers need to be knowledgeable about palliative care, and they need supportive organizations with clear expectations and goals about palliative care. Future action and learning oriented research projects for the implementation of palliative care principles, in which first line managers actively participate, are suggested.

    To evaluate the efficacy and tolerability of levetiracetam monotherapy in dogs with structural epilepsy. Retrospective case series. Nineteen client-owned dogs with structural epilepsy. Seizure frequencies after initiation of treatment were used to evaluate the efficacy of levetiracetam monotherapy. Seizure control was considered good if no seizures occurred within three months of starting treatment or poor if seizures returned within one month of starting treatment. Tolerability was evaluated by considering the occurrence and severity of any reported side effects. Ten of the 19 dogs were considered to have a good response to treatment with 7 achieving complete seizure freedom. Nine dogs were considered to have poor response to treatment. There was a statistically significant reduction in the percentage of patients experiencing cluster seizures from 68.4% to 15.8% (p=0.002). Side effects were noted in 8 of the 19 dogs but were considered mild in all cases. Follow-up times ranged from 12 days to 426 days. When used in conjunction with other appropriate therapies, levetiracetam may be an efficacious option for monotherapy in dogs with structural epilepsy. Its tolerability makes it a suitable option for use in a wide variety of patients. © British Veterinary Association (unless otherwise stated in the text of the article) 2017. All rights reserved.

    2007-01-01

    This study investigates whether first-line nurse managers in hospitals share common dispositions related to managerial work and leadership, what they are like, and what their relationship is with the various expectations set on them. The first data were collected by focus group interviews in the autumn of 2000 and analysed using qualitative content analysis and frame analysis. The second data set were part of a questionnaire survey addressed to the same managers in 2001 with a focus on their diverse leadership roles. Among first-line nurse managers, the management frameworks of a nurturing mother and an administrative nurse displayed the strongest prominence, and the emphasis seemed to be evolving towards the administrative. The results from the survey confirmed the findings of this study in relation to first-line nurse managers' management frameworks. The line of development found in this study may add to the permanence of operations and the stability of the operative culture at a university hospital. It may also diminish the opportunities for nursing development in university hospital wards and weaken the potential for a new kind of competence among both managers and their subordinates.

  1. Severe pneumonia associated with ibrutinib monotherapy for CLL and lymphoma.

    2018-02-01

    In recent years, there have been major advances in the treatment of chronic lymphocytic leukemia (CLL) particularly since the development of novel therapeutic agents, mostly "biological drugs." One of the obvious advantages of these agents is the decreased rate of infectious complications occurring during the course of therapy, compared to the use of standard immuno-chemotherapy regimens. Here, we describe 3 patients with CLL and 1 with mantle cell lymphoma who developed severe life-threatening pneumonias, during monotherapy with ibrutinib. The first case was a 70-year-old woman with relapsed CLL who developed bilateral pneumonia with hypoxia 1 week after starting ibrutinib. She did not respond to broad-spectrum antibiotics and was treated empirically with trimethoprim-sulphamethoxazole and improved. In the second case, we describe a 76-year-old woman with relapsed CLL who developed recurrent pneumonia after 3 years of treatment with ibrutinib. Presuming that ibrutinib was the cause of pneumonitis with secondary infection, it was stopped with subsequent improvement. The third patient a 67 year-old man died because of severe bilateral necrotizing pneumonia due to invasive aspergillosis and mucormycosis with pulmonary hemorrhage. The fourth patient with relapsed mantle cell lymphoma died because of severe bilateral pneumonia, caused by pseudomonas and candida, despite receiving appropriate antibiotics. From this experience, we hypothesize that the etiology of severe pneumonia associated with ibrutinib treatment is probably multifactorial, involving factors like preexisting immune-suppression, drug induced pneumonitis and infections. We suggest that patients with CLL or other lymphoproliferative disorders with suspected pneumonia during monotherapy with ibrutinib should be very carefully evaluated and need to undergo complete diagnostic workup to establish an exact diagnosis. Understanding which patients with CLL or lymphoma treated with kinase inhibitors are at a

    The aim of this study was to evaluate the treatment outcomes of intravitreal bevacizumab (IVB) injections, used as a monotherapy in type 1 retinopathy of prematurity (ROP). A retrospective chart review was performed for 17 type 1 ROP patients (34 eyes), who had IVB injection between July 2011 and June 2012. Birthweight, gestational age at birth, stage and location of ROP, IVB injection time, time of complete retinal vascularization, and additional treatments if needed, were noted. A total of 0.625 mg (0.025 mL) bevacizumab was injected intravitreally. Thirty eyes of 17 patients with type 1 ROP enrolled in the study were treated with IVB injection. Of them seven had aggressive posterior-ROP, six had stage 2 ROP, and four had stage 3 ROP. The mean gestational age was 28.44 weeks (range, 26-31 weeks); and the mean birthweight was 1151.88 g (range, 600-1600 g). The mean age for IVB injection was 35.47 weeks. The mean full retinal vascularization time was 136.6 ± 26.6 days. The mean follow-up time was 285.3 ± 70 days. ROP was regressed and retinal vascularization was completed in all cases except one eye, which had threshold disease. IVB injection, used as a monotherapy, is an effective treatment approach in patients with type 1 ROP. Timely treatment of stage 2 and early stage 3 ROP in which disease progression was observed, prevents vitreoretinal membrane formation in posterior disease. Further studies need to be performed to determine the safety of IVB injection. © 2013 The Authors. Pediatrics International © 2013 Japan Pediatric Society.

    Helicobacter pylori eradication is a challenge in penicillin allergy. To assess the efficacy and safety of first-line and rescue treatments in patients allergic to penicillin. Prospective multicenter study. Patients allergic to penicillin were given a first-line treatment comprising (a) 7-day omeprazole-clarithromycin-metronidazole and (b) 10-day omeprazole-bismuth-tetracycline-metronidazole. Rescue treatments were as follows: (a) bismuth quadruple therapy; (b) 10-day PPI-clarithromycin-levofloxacin; and (c) 10-day PPI-clarithromycin-rifabutin. Eradication was confirmed by (13)C-urea breath test. Compliance was determined through questioning and recovery of empty medication envelopes. Adverse effects were evaluated by questionnaires. In total, 267 consecutive treatments were included. (1) First-line treatment: Per-protocol and intention-to-treat eradication rates with omeprazole-clarithromycin-metronidazole were 59 % (62/105; 95 % CI 49-62 %) and 57 % (64/112; 95 % CI 47-67 %). Respective figures for PPI-bismuth-tetracycline-metronidazole were 75 % (37/49; 95 % CI 62-89 %) and 74 % (37/50; 95 % CI (61-87 %) (p < 0.05). Compliance with treatment was 94 and 98 %, respectively. Adverse events were reported in 14 % with both regimens (all mild). (2) Second-line treatment: Intention-to-treat eradication rate with omeprazole-clarithromycin-levofloxacin was 64 % both after triple and quadruple failure; compliance was 88-100 %, with 23-29 % adverse effects (all mild). (3) Third-/fourth-line treatment: Intention-to-treat eradication rate with PPI-clarithromycin-rifabutin was 22 %. In allergic to penicillin patients, a first-line treatment with a bismuth-containing quadruple therapy (PPI-bismuth-tetracycline-metronidazole) seems to be a better option than the triple PPI-clarithromycin-metronidazole regimen. A levofloxacin-based regimen (together with a PPI and clarithromycin) represents a second-line rescue option in the presence of penicillin allergy.

    The combination of pemetrexed and platinum compound represents the standard regimen for first-line chemotherapy in malignant pleural mesothelioma patients. Pemetrexed is a multitarget antifolate agent that inhibits folate-dependent enzymes (eg, thymidylate synthase [TS]) and thus synthesis of nucleotides and DNA. Expression of TS and folate availability, regulated by gene polymorphisms, have implications for effectiveness of chemotherapy and the outcome of mesothelioma patients. The aim of this retrospective multicenter study was to assess the correlation between TS, 5,10-methylenetetrahydrofolate reductase (MTHFR) and excision repair cross-complementing group 1 (ERCC1) gene polymorphisms and the efficacy of pemetrexed-based first-line chemotherapy of mesothelioma patients. Fifty-nine mesothelioma patients (31 men with a median age of 62 years) treated in first-line chemotherapy with platinum in combination with pemetrexed or pemetrexed monotherapy were enrolled. Genomic DNA was isolated from peripheral blood. Using polymerase chain reaction and high resolution melt methods, the variable number of tandem repeat, the G>C single nucleotide polymorphism (SNP) in these repeats, and 6-base pair (bp) insertion/deletion polymorphism of the TS gene, the SNP of 677C>T in MTHFR, and 19007C>T in the ERCC1 gene were analyzed and correlated with disease control rate, progression-free survival (PFS), and overall survival (OS) of mesothelioma patients. Greater risk of early disease progression (PD), and shortening of PFS and OS were associated with several clinical factors (eg, anemia for early PD and OS), weight loss (for PFS and OS), and previous surgical treatment (for early PD, PFS, and OS). Insertion of 6-bp in both alleles of the TS gene (1494del6) was the only genetic factor that increased the incidence of early progression (P = .028) and shortening of median PFS (P = .06) in patients treated with pemetrexed-based chemotherapy. In multivariate analysis, the 1494del6 in the

    Colistin-based combination therapy (CCT) is extensively used to treat infections due to carbapenem-resistant Gram-negative bacteria (CRGNB). There are no data available from India on the usefulness of combination therapy, especially in the oncology setup. The aim of this study was to analyze the clinical effectiveness of CCT over monotherapy in patients with CRGNB. We conducted a retrospective, observational study of patients with CRGNB bloodstream infections in our oncology and bone marrow transplant center. Over a 3-year study period (2011-2014), we could identify 91 patients satisfying study criteria. There was no statistically significant difference in the 28-day mortality between monotherapy and combination therapy arms (mono n = 26, mortality 10 (38.5%); combination n = 65, mortality 28 (40%); P = 0.886). Neutropenic patients with Enterobacteriaceae bloodstream infections performed better with combination therapy (mono n = 7, mortality 6 (85.7%); combination therapy n = 22, mortality 8 (36.4%); P = 0.035). There was no significant difference in the 28-day mortality between the two treatment arms in other subgroups. Our study did not find CCT superior to colistin monotherapy in patients with CRGNB blood stream infections; except in the subgroup of neutropenic patients with Enterobacteriaceae bloodstream infections, where combination therapy performed better.

    To compare the effect of repaglinide in combination with metformin with monotherapy of each drug on glycemic control in patients with type 2 diabetes. A total of 83 patients with type 2 diabetes who had inadequate glycemic control (HbA1c > 7.1%) when receiving the antidiabetic agent metformin were enrolled in this multicenter, double-blind trial. Subjects were randomized to continue with their prestudy dose of metformin (n = 27), to continue with their prestudy dose of metformin with the addition of repaglinide (n = 27), or to receive repaglinide alone (n = 29). For patients receiving repaglinide, the optimal dose was determined during a 4- to 8-week titration and continued for a 3-month maintenance period. In subjects receiving combined therapy, HbA1c was reduced by 1.4 +/- 0.2%, from 8.3 to 6.9% (P = 0.0016) and fasting plasma glucose by 2.2 mmol/l (P = 0.0003). No significant changes were observed in subjects treated with either repaglinide or metformin monotherapy in HbA1c (0.4 and 0.3% decrease, respectively) or fasting plasma glucose (0.5 mmol/l increase and 0.3 mmol/l decrease respectively). Subjects receiving repaglinide either alone or in combination with metformin, had an increase in fasting levels of insulin between baseline and the end of the trial of 4.04 +/- 1.56 and 4.23 +/- 1.50 mU/l, respectively (P < 0.02). Gastrointestinal adverse events were common in the metformin group. An increase in body weight occurred in the repaglinide and combined therapy groups (2.4 +/- 0.5 and 3.0 +/- 0.5 kg, respectively; P < 0.05). Combined metformin and repaglinide therapy resulted in superior glycemic control compared with repaglinide or metformin monotherapy in patients with type 2 diabetes whose glycemia had not been well controlled on metformin alone. Repaglinide monotherapy was as effective as metformin monotherapy.

    The number of studies evaluating the efficacy and safety of third-line molecular-targeted therapy for metastatic renal cell carcinoma (mRCC) is limited. The data for 48 patients with disease progression after first-line vascular endothelial growth factor receptor tyrosine kinase inhibitor (TKI) and second-line targeted therapy were evaluated. Patients with prior cytokine therapy were excluded. Overall survival (OS) after first- and second-line therapy initiation was compared between patients with and without third-line therapy. In addition, dose-limiting toxicities (DLTs) were evaluated. Twenty-two of 48 patients (45.8%) received third-line therapy, and TKI and mammalian target of rapamycin inhibitor were each administered in 11 patients (50%). Patients with third-line therapy had significantly longer median OS after first-line therapy (26.6 vs. 14.6 months, p = 0.0010) and second-line therapy (18.2 vs. 7.4 months, p < 0.0001) compared to those without third-line therapy. Multivariate analysis showed that the use of third-line therapy following second-line therapy was an independent prognosticator for longer OS (hazard ratio 0.29, 95% confidence interval 0.14-0.58, p = 0.0005). The median progression-free survival and OS after third-line therapy was 2.76 and 8.71 months, respectively. Although a high frequency of DLTs was observed (n = 10, 45.5%), the frequencies were similar among the sequential therapies. Third-line therapy has a beneficial therapeutic effect in patients with mRCC that is resistant to previous therapies. However, there is a need to evaluate in detail the high frequency of adverse events, including DLTs.

    Fenofibrate is a fibric acid derivative indicated for use in hypertriglyceridemia and mixed dyslipidemia treatment among adults. Rhabdomyolysis is a syndrome characterized by muscle necrosis and the release of intracellular muscle contents into the systemic circulation, which is the most serious and fatal side effect of fenofibrate. The objective of this paper is to discuss fatal side effect of fenofibrate and keep safe medication. A patient with hypothyroidism who presented with rhabdomyolysis during fenofibrate monotherapy for hypertriglyceridemia was reported. Fenofibrate Monotherapy Induced Rhabdomyolysis. Fenofibrate was stopped. Adequate fluid resuscitation, mannitol diuresis, myocardium protection, hepatoprotection and urine alkalinization with sodium bicarbonate were performed. Blood tests were normal and the patient was good and discharged 2 weeks later. 13 cases associated with fenofibrate monotherapy-induced rhabdomyolysis were reviewed, which had been published in the English literature. The severity of fenofibrate muscle toxicity may be the result of the combination of two rhabdomyolysis enhancers, such as hypothyroidism and female gender. To avoid it, strict clinical and laboratory monitoring should be maintained, particularly hypothyroidism. Patients should be informed of possible potentially irreversible effects after taking fibrates.

    After progression to a standard first-line platinum and gemcitabine combination (GP), there is no established second-line therapy for patients with advanced biliary tract cancers (aBTC). Indeed, literature data suggest limited activity of most second-line agents evaluated so far. We collected a large retrospective series of aBTC patients treated with second-line chemotherapy after progression to a first-line GP regimen at different Italian institutions. We then pooled the data with those reported in previous studies, which were identified with a Medline search and the on-line abstract datasets of major international oncology meetings. A total of 174 patients were included in the multicenter survey: response rate (RR) with second-line chemotherapy was low (3.4 %), with median PFS and OS of 3.0 months and 6.6 months, respectively. At multivariate analysis, preserved performance status, low CA19.9 levels and absence of distant metastases were favorable prognostic factors. Data from other five presented or published series were identified, for a total of 499 patients included in the pooled analysis. The results confirmed marginal activity of second-line chemotherapy (RR: 10.2 %), with limited efficacy in unselected patient populations (median PFS: 3.1 months; median OS: 6.3 months). The current analysis highlights the limited value of second-line chemotherapy after a first-line GP combination in aBTC. While waiting for effective biologic agents in this setting, ongoing randomized trials will identify the optimal second-line chemotherapy regimen and validate prognostic factors for individual patient management.

    Fish oil monotherapy has been an advance for treating intestinal failure-associated liver disease (IFALD). However, such patients are at risk of bleeding complications from liver disease and because fish oil can inhibit thrombosis. We have previously reported abnormal platelet function in neonatal piglets given fish oil monotherapy during parenteral nutrition (PN). The purpose of this study was to determine if abnormal fatty acid composition of the platelets could explain the prior observed antiplatelet effect. Neonatal piglets were assigned to 2 treatments: PN with fish oil monotherapy (FO; n = 4) or PN with soy oil (SO; n = 5). On day 14, plasma was collected and platelets isolated by centrifuging. The fatty acid content in plasma and platelet plug were measured using gas liquid chromatography and compared with controls (CON; n = 5). The arachidonic acid (AA) content in the FO group was on average half that of the SO group, in both the platelets (FO, 3.5% vs SO, 7.6%; P = .021; CON, 4.5%-11%) and the plasma (FO, 3.8% vs SO, 9.2%; P = .002; CON, 6.1%-9.5%). No bleeding complications were observed for any piglets during PN treatment. Using platelet mapping, we have previously shown that neonatal piglets given fish oil monotherapy have abnormal platelet function in the AA pathway. This report demonstrates that such an abnormality can be explained by platelet AA deficiency. Platelet mapping and platelet fatty acid analysis should be undertaken in human infants treated with fish oil monotherapy during PN. © 2015 American Society for Parenteral and Enteral Nutrition.

    The aim was to analyse trends in clinically relevant resistance to first-line antiretroviral drugs in Spain, applying the Stanford algorithm, and to compare these results with reported Transmitted Drug Resistance (TDR) defined by the 2009 update of the WHO SDRM list. We analysed 2781 sequences from ARV naive patients of the CoRIS cohort (Spain) between 2007-2011. Using the Stanford algorithm "Low-level resistance", "Intermediate resistance" and "High-level resistance" categories were considered as "Resistant". 70% of the TDR found using the WHO list were relevant for first-line treatment according to the Stanford algorithm. A total of 188 patients showed clinically relevant resistance to first-line ARVs [6.8% (95%Confidence Interval: 5.8-7.7)], and 221 harbored TDR using the WHO list [7.9% (6.9-9.0)]. Differences were due to a lower prevalence in clinically relevant resistance for NRTIs [2.3% (1.8-2.9) vs. 3.6% (2.9-4.3) by the WHO list] and PIs [0.8% (0.4-1.1) vs. 1.7% (1.2-2.2)], while it was higher for NNRTIs [4.6% (3.8-5.3) vs. 3.7% (3.0-4.7)]. While TDR remained stable throughout the study period, clinically relevant resistance to first line drugs showed a significant trend to a decline (p = 0.02). Prevalence of clinically relevant resistance to first line ARVs in Spain is decreasing, and lower than the one expected looking at TDR using the WHO list. Resistance to first-line PIs falls below 1%, so the recommendation of screening for TDR in the protease gene should be questioned in our setting. Cost-effectiveness studies need to be carried out to inform evidence-based recommendations.

    Introduction Lung cancer, the most prevalent malignant cancer in the world, remains a serious threat to public health. Recently, a large number of studies have shown that an epidermoid growth factor receptor-tyrosine kinase inhibitor (EGFR TKI), Erlotinib, has significantly better efficacy and is better tolerated in advanced non-small cell lung cancer (NSCLC) patients with a positive EGFR gene mutation. However, access to this drug is severely limited in China due to its high acquisition cost. Therefore, we decided to conduct a study to compare cost-effectiveness between erlotinib monotherapy and carboplatin-gemcitabine (CG) combination therapy in patients with advanced EGFR mutation-positive NSCLC. Methods A Markov model was developed from the perspective of the Chinese health care system to evaluate the cost-effectiveness of the two treatment strategies; this model was based on data from the OPTIMAL trial, which was undertaken at 22 centres in China. The 10-year quality-adjusted life years (QALYs), direct costs, and incremental cost-effectiveness ratio (ICER) were estimated. To allow for uncertainties within the parameters and to estimate the model robustness, one-way sensitivity analysis and probabilistic sensitivity analysis were performed. Results The median progression-free survival (PFS) obtained from Markov model was 13.2 months (13.1 months was reported in the trial) in the erlotinib group while and 4.64 months (4.6 months was reported in the trial) in the CG group. The QALYs were 1.4 years in the erlotinib group and 1.96 years in the CG group, indicating difference of 0.56 years. The ICER was most sensitive to the health utility of DP ranged from $58,584.57 to $336,404.2. At a threshold of $96,884, erlotinib had a 50%probability of being cost-effective. Conclusions Erlotinib monotherapy is more cost-effective compared with platinum-based doublets chemotherapy as a first-line therapy for advanced EGFR mutation- positive NSCLC patients from within the

    A majority of patients with advanced or metastatic non-small cell lung cancer (NSCLC) will experience disease progression after first-line therapy. Patients who have advanced NSCLC that is especially aggressive, which is defined as disease that rapidly progresses on first-line treatment or disease that is refractory to first-line treatment, have a critical unmet medical need. These patients have a poor prognosis in the second-line setting. Several studies have recently shown that treatment with an antiangiogenic therapy may benefit these patients. This review summarizes the approved antiangiogenic therapies for the treatment of patients with advanced NSCLC in the second-line setting, specifically focusing on the outcomes from subgroups of patients with rapidly progressing or refractory disease. Several antiangiogenic agents, as monotherapy or in combination with other treatments, have been or are currently being studied in patients with advanced NSCLC. Antiangiogenics that are approved for use in patients with advanced NSCLC are limited to bevacizumab in combination with chemotherapy (nonsquamous NSCLC), ramucirumab in combination with docetaxel (all histologies), and nintedanib in combination with docetaxel (adenocarcinoma histology). This review focuses on the efficacy, safety, and quality of life outcomes in the subpopulation of patients with rapidly progressing or refractory NSCLC treated with approved antiangiogenic therapies in the second-line setting. We also discuss the impact of newly approved immunotherapy agents on the outcomes of patients with aggressive or refractory disease. Studies in progress and planned future research will determine if combination treatment with antiangiogenics and immunotherapies will benefit patients with aggressive, advanced NSCLC.

    In this post hoc analysis of the EDGE study, we assessed the effectiveness and safety of vildagliptin versus other oral antidiabetes drugs (OADs) as add-on to first-line sulphonylurea (SU) therapy in patients who did not receive metformin in a real-life setting. The primary endpoint was odds of achieving an HbA1c reduction of >0.3% without tolerability issues. Secondary endpoint was odds of achieving HbA1c <7.0% without hypoglycaemia or weight gain. Changes in HbA1c, body weight; and safety were also assessed. 2936 patients received vildagliptin and 820 received comparator OADs (any α-GI, TZD, glinide) as add-on to first-line SU therapy. Overall, the mean age, disease duration, HbA1c, and BMI at baseline were 57.1 years, 6.3 years, 8.5%, and 27.7kg/m 2 , respectively. The odds ratios for achieving primary and secondary endpoints were 1.6 (95% CI: 1.36, 1.86; p<0.0001) and 1.8 (1.45, 2.21; p<0.0001), respectively, in favour of vildagliptin. The between-treatment differences (vildagliptin vs. comparator OAD) for the mean change in HbA1c and body weight were -0.2±0.04% (p<0.0001) and -0.8±0.16kg (p<0.0001), respectively. Overall, the incidence of adverse events was low (vildagliptin, 7% vs. comparator, 8.2%) in both groups. Similar results were observed in a subset of patients enrolled from India and patients who received TZDs as a comparator OAD. Under real-life settings, vildagliptin as add-on to SU monotherapy showed better glycaemic response without tolerability issues compared with other OADs.

    Prior studies suggested that glaucoma patients suffer worse dry eye and mood and sleep disorders than non-glaucoma subjects. Prostaglandin analogues are first-line therapy for glaucoma, inducing few instillation problems and sufficient pressure-reduction effects. This study compared dry eye, sleep quality, and mood status between glaucoma patients receiving prostaglandin monotherapy and non-glaucoma subjects. This cross-sectional study evaluated 1520 patients (579 males and 941 females) for glaucoma status and dry eye-related symptoms (dryness, eye fatigue, photophobia, pain, blurring) and signs (Schirmer test, tear break-up time, corneal staining scores). Of the total cohort, 93 patients were also evaluated by Pittsburgh sleep quality index (PSQI) and hospital anxiety and depression score (HADS). Inclusion criteria were consecutive patients ≥ 51 years of age and best-corrected visual acuity ≥ 20/25. Glaucoma patients included those treated with prostaglandin or a fixed combination including prostaglandin. Exclusion criteria were history of ocular surgery within one month. Data were analyzed using the chi-square or Mann-Whitney U tests, at 5% significance. There were no significant differences in dry eye-related signs and symptoms between the control (n = 1431, mean age of 66.9 years) and glaucoma groups (n = 89, 67.9 years). The psychiatric sub-analysis of the control (n = 61, 66.2 years) and glaucoma groups (n = 32, 67.3 years) revealed mean scores of 5.02 ± 3.10 and 5.16 ± 3.46 for PSQI (normal range ≤ 5), 9.47 ± 5.61 and 9.42 ± 7.36 for HADS (normal range ≤ 10), 4.84 ± 3.22 and 4.71 ± 3.45 for anxiety (normal range ≤ 5), and 4.63 ± 3.05 and 4.71 ± 4.40 for depression (normal range ≤ 5), respectively, without statistical significance. Our results were comparable between glaucoma patients on prostaglandin monotherapy and non-glaucoma subjects for dry eye-related clinical manifestations, sleep quality, and mood status.

    It has been proven that icotinib hydrochloride, as a molecule targeted drug, can be safely and efficiently used to treat advanced non-small cell lung cancer (NSCLC) for second-line or third-line. This research was aimed to investigate the efficacy and toxicity of icotinib hydrochloride as the first-line therapy for pulmonary adenocarcinoma. Among the 56 patients, the tumor objective response rate (ORR) and disease control rate (DCR) was 46.4% (26/56) and 78.6% (46/56), respectively. Among the 20 patients with EGFR analyses, 18 patients were positive for a mutation, ORR was 66.7% (12/18), DCR was 94.4% (17/18) respectively. The ORR with no history of smoke. EGFR positive mutation and appearance of rash were significantly higher than those with smoker, wild type EGFR, no information about EGFR and no appearance of rash (P<0.05). The most common drug-related adverse events were mild skin rash (28.5%) and diarrhea (12%). Single agent treatment with icotinib hydrochloride is effective and tolerable in first-line therapy for pulmonary adenocarcinoma, especially with EGFR mutation.

    To summarize published data regarding the use of ceftaroline as salvage monotherapy for persistent methicillin-resistant Staphylococcus aureus (MRSA) bacteremia. PubMed (January 1980-June 2016) was searched using combinations of the search terms methicillin-resistant Staphylococcus aureus, MRSA, bacteremia, ceftaroline, refractory, and persistent Supplemental references were generated through review of identified literature citations. Available English-language, full-text articles pertaining to the use of ceftaroline for persistent MRSA bacteremia (MRSAB) were included. The PubMed search yielded 23 articles for evaluation. There are no randomized controlled trials to date-only case series and reports. Four retrospective case series detailing the use of ceftaroline as monotherapy for persistent MRSAB were included. Most patients received at least 4 days of an appropriate anti-MRSA antimicrobial prior to ceftaroline and were able to clear bacteremia within 3 days. The most common rationales for ceftaroline use were progression of disease or nonresponse to current therapy. Higher off-label dosing of ceftaroline is often utilized to achieve optimal pharmacokinetic/pharmacodynamic parameters. Adverse events are not well described due to lack of follow-up; however, neutropenia has been associated with prolonged use. Treatment options for persistent MRSAB remain few and far between. Ceftaroline is an effective agent for the salvage treatment of MRSAB. Off-label doses up to 600 mg every 8 hours are often used to achieve optimal pharmacokinetic/pharmacodynamic parameters. Because of lack of follow-up in these reports, the incidence of adverse effects of prolonged use of ceftaroline is not well defined. © The Author(s) 2016.

    The cost-effectiveness of first-line tyrosine kinase inhibitor therapy in epidermal growth factor receptor gene (EGFR)-mutated advanced-stage non-small cell lung cancer (NSCLC) is poorly documented. We therefore conducted a cost-effectiveness analysis of first-line treatment with erlotinib versus standard chemotherapy in European patients with advanced-stage EGFR-mutated NSCLC who were enrolled in the European Erlotinib versus Chemotherapy trial. The European Erlotinib versus Chemotherapy study was a multicenter, open-label, randomized phase III trial performed mainly in Spain, France, and Italy. We based our economic analysis on clinical data and data on resource consumption (drugs, drug administration, adverse events, and second-line treatments) collected during this trial. Utility values were derived from the literature. Incremental cost-effectiveness ratios were calculated for the first-line treatment phase and for the overall strategy from the perspective of the three participating countries. Sensitivity analyses were performed by selecting the main cost drivers. Compared with standard first-line chemotherapy, the first-line treatment with erlotinib was cost saving (€7807, €17,311, and €19,364 for Spain, Italy and France, respectively) and yielded a gain of 0.117 quality-adjusted life-years. A probabilistic sensitivity analysis indicated that, given a willingness to pay at least €90,000 for 1 quality-adjusted life-year, the probability that a strategy of first-line erlotinib would be cost-effective was 100% in France, 100% in Italy, and 99.8% in Spain. This economic analysis shows that first-line treatment with erlotinib, versus standard chemotherapy, is a dominant strategy for EGFR-mutated advanced-stage NSCLC in three European countries.

    Background: The International Maternal, Pediatric, and Adolescent Clinical Trials P1060 trial demonstrated superior outcomes for HIV-infected children less than 3 years old initiating antiretroviral therapy (ART) with lopinavir/ritonavir compared to nevirapine, but lopinavir/ritonavir is four-fold costlier. Design/methods: We used the Cost-Effectiveness of Preventing AIDS Complications (CEPAC)-Pediatric model, with published and P1060 data, to project outcomes under three strategies: no ART; first-line nevirapine (with second-line lopinavir/ritonavir); and first-line lopinavir/ritonavir (second-line nevirapine). The base-case examined South African children initiating ART at age 12 months; sensitivity analyses varied all key model parameters. Outcomes included life expectancy, lifetime costs, and incremental cost-effectiveness ratios [ICERs; dollars/year of life saved ($/YLS)]. We considered interventions with ICERs less than 1× per-capita gross domestic product (South Africa: $7500)/YLS as ‘very cost-effective,’ interventions with ICERs below 3× gross domestic product/YLS as ‘cost-effective,’ and interventions leading to longer life expectancy and lower lifetime costs as ‘cost-saving’. Results: Projected life expectancy was 2.8 years with no ART. Both ART regimens markedly improved life expectancy and were very cost-effective, compared to no ART. First-line lopinavir/ritonavir led to longer life expectancy (28.8 years) and lower lifetime costs ($41 350/person, from lower second-line costs) than first-line nevirapine (27.6 years, $44 030). First-line lopinavir/ritonavir remained cost-saving or very cost-effective compared to first-line nevirapine unless: liquid lopinavir/ritonavir led to two-fold higher virologic failure rates or 15-fold greater costs than in the base-case, or second-line ART following first-line lopinavir/ritonavir was very ineffective. Conclusions: On the basis of P1060 data, first-line lopinavir/ritonavir leads to longer life

    Long-term therapy with phenytoin and carbamazepine is known to cause hyperhomocysteinaemia. We evaluated the prevalence of hyperhomocysteinaemia in North Indian children receiving phenytoin or carbamazepine monotherapy for >6 months duration and the effect of folic acid supplementation on plasma homocysteine. In this cross-sectional observational study we enrolled consecutive children aged 2-12 years with epilepsy who had received phenytoin or carbamazepine monotherapy for >6 months. Plasma total homocysteine, folic acid, vitamin B12 and antiepileptic drug concentrations were measured. Healthy age- and sex-matched controls were recruited. Children with homocysteine >10.4 µmol/L received folic acid supplementation for 1 month and homocysteine and folic acid concentrations were measured after 1 month follow-up. A total of 112 children receiving antiepileptic monotherapy for >6 months were enrolled. Hyperhomocysteinaemia was present in 54 children (90%) receiving phenytoin, 45 children (90%) receiving carbamazepine therapy and 17 (34%) controls (p<0.05). Mean plasma homocysteine concentrations were significantly higher (18.9±10.2 vs 9.1±3 µmol/L) and serum folic acid concentrations (10.04±8.5 ng/ml vs 12.6±4.8 p<0.001) and vitamin B12 concentrations (365±155 pg/mL vs 474±332 pg/mL, p=0.02) were significantly lower in the study group compared with the control group. Duration of antiepileptic drug therapy correlated significantly with elevated homocysteine and reduced folic acid concentrations (p<0.05). Supplementation with folic acid for 1 month led to a reduction in plasma homocysteine concentrations in the study group (from 20.9±10.3 µmol/L to 14.2±8.2 µmol/L, p<0.05). Phenytoin or carbamazepine monotherapy for >6 months duration is associated with hyperhomocysteinaemia in 90% of North Indian children. Elevated homocysteine concentrations were normalised in these children with folic acid supplementation. Published by the BMJ

    To examine nurse leaders' change management projects within British Columbia, Canada. British Columbia Nursing Leadership Institute 2007-10 attendees worked on year-long change management initiatives/projects of importance to their respective health-care institutions. Most leaders were in first-line positions with <3 years' experience. Consenting leaders' project reports (N = 133) were content analysed for specific themes: types of projects; scope of projects (e.g. unit or local level, departmental, institutional); influence targets or key stakeholder groups targeted by the projects; leadership successes and challenges. Of study participants, 77% successfully completed their projects. Staff tool and resource development and existing services improvement were major project types. Care delivery teams were the major influence targets. Only 25% of projects were at the unit level. Many projects had broader scopes, such as institutional levels. Participants cited multiple leadership successes, including enhanced leadership styles and organizational skills. First-line nurse leaders were able to successfully manage projects beyond their traditional scope of responsibilities. The majority of projects dealt with staff needs and healthcare restructuring initiatives. Constant change is a global reality. Change management, a universal competency, must be included in leadership development programmes. © 2011 Blackwell Publishing Ltd.

    Verbal working memory and emotional self-regulation are impaired in Bipolar Disorder (BD). Our aim was to investigate the effect of Lamotrigine (LTG), which is effective in the clinical management of BD, on the neural circuits subserving working memory and emotional processing. Functional Magnetic Resonance Imaging data from 12 stable BD patients was used to detect LTG-induced changes as the differences in brain activity between drug-free and post-LTG monotherapy conditions during a verbal working memory (N-back sequential letter task) and an angry facial affect recognition task. For both tasks, LGT monotherapy compared to baseline was associated with increased activation mostly within the prefrontal cortex and cingulate gyrus, in regions normally engaged in verbal working memory and emotional processing. Therefore, LTG monotherapy in BD patients may enhance cortical function within neural circuits involved in memory and emotional self-regulation.

    We conducted an adjusted comparison of progression-free survival (PFS) and overall survival (OS) for daratumumab monotherapy versus standard of care, as observed in a real-world historical cohort of heavily pretreated multiple myeloma patients from Czech Republic. Using longitudinal chart data from the Registry of Monoclonal Gammopathies (RMG) of the Czech Myeloma Group, patient-level data from the RMG was pooled with pivotal daratumumab monotherapy studies (GEN501 and SIRIUS; 16 mg/kg). From the RMG database, we identified 972 treatment lines in 463 patients previously treated with both a proteasome inhibitor and an immunomodulatory drug. Treatment initiation dates for RMG patients were between March 2006 and March 2015. The most frequently used treatment regimens were lenalidomide-based regimens (33.4%), chemotherapy (18.1%), bortezomib-based regimens (13.6%), thalidomide-based regimens (8.0%), and bortezomib plus thalidomide (5.3%). Few patients were treated with carfilzomib-based regimens (2.5%) and pomalidomide-based regimens (2.4%). Median observed PFS for daratumumab and the RMG cohort was 4.0 and 5.8 months (unadjusted hazard ratio [HR], 1.14; 95% confidence interval [CI], 0.94-1.39), respectively, and unadjusted median OS was 20.1 and 11.9 months (unadjusted HR, 0.61; 95% CI, 0.48-0.78), respectively. Statistical adjustments for differences in baseline characteristics were made using patient-level data. The adjusted HRs (95% CI) for PFS and OS for daratumumab versus the RMG cohort were 0.79 (0.56-1.12; p = .192) and 0.33 (0.21-0.52; p < .001), respectively. Adjusted comparisons between trial data and historical cohorts can provide useful insights to clinicians and reimbursement decision makers on relative treatment efficacies in the absence of head-to-head comparison studies for daratumumab monotherapy.

    Many older adults with Major Depressive Disorder (MDD) do not respond to antidepressant monotherapy. While there are evidence-based treatment options to support treatment beyond monotherapy for adults, the evidence for such strategies specifically in late-life MDD is relatively scarce. This review examines the published data describing strategies for antidepressant augmentation or acceleration studied specifically in older adults, including lithium, stimulants, and second-generation antipsychotics. In addition, the authors suggest strategies for future research, such as study of specific agents, refining understanding of the impact of medical or cognitive comorbidity in late-life depression, and comparative effectiveness to examine methods already used in clinical practice.

    To evaluate whether in chronic hepatitis C-positive patients who failed to respond to interferon (IFN) monotherapy a sustained response obtained with retreatment using the combination therapy of IFN + ribavirin can be safely considered to reflect eradication of the infection. Prospective follow-up of a cohort of 97 patients who responded to retreatment with different regimens of IFN + ribavirin after failing to respond to a first IFN monotherapy course. The patients were followed throughout 7 yr of follow-up with determinations of HCV viremia every 6 months. At the end of the follow-up, 11 patients (11.3%) showed a viremic reappearance. HCV late relapse rates were 0%, 13%, 20%, and 12% in patients retreated, respectively, with 3 MU IFN + ribavirin for 12 months (Group 1), 5 MU IFN + ribavirin for 12 months (Group 2), 3 MU IFN + ribavirin for 6 months (Group 3), and 5 MU IFN + ribavirin for 6 months (Group 4) (Group 2 vs Group 3, p= 0.005). The virologic relapses occurred within 2 yr from therapy withdrawal. Among patients with genotype 1 and 4, the long-term response was significantly higher in Group 2 than in Group 3 (15%vs 3%, p= 0.03). In patients with genotype 2 and 3, the long-term virological response was not affected by the different regimens. Nonresponders to IFN monotherapy who achieve a sustained virologic response after retreatment with IFN + ribavirin stand a discrete risk of HCV reactivation within 2 yr after therapy.

    Abstract Background: We compared efficacy and treatment persistence in treatment-naive patients with relapsing-remitting multiple sclerosis (RRMS) initiating natalizumab compared with interferon-β (IFN-β)/glatiramer acetate (GA) therapies, using propensity score–matched cohorts from observational multiple sclerosis registries. Methods: The study population initiated IFN-β/GA in the MSBase Registry or natalizumab in the Tysabri Observational Program, had ≥3 months of on-treatment follow-up, and had active RRMS, defined as ≥1 gadolinium-enhancing lesion on cerebral MRI at baseline or ≥1 relapse within the 12 months prior to baseline. Baseline demographics and disease characteristics were balanced between propensity-matched groups. Annualized relapse rate (ARR), time to first relapse, treatment persistence, and disability outcomes were compared between matched treatment arms in the total population (n = 366/group) and subgroups with higher baseline disease activity. Results: First-line natalizumab was associated with a 68% relative reduction in ARR from a mean (SD) of 0.63 (0.92) on IFN-β/GA to 0.20 (0.63) (p [signed-rank] < 0.0001), a 64% reduction in the rate of first relapse (hazard ratio [HR] 0.36, 95% confidence interval [CI] 0.28–0.47; p < 0.001), and a 27% reduction in the rate of discontinuation (HR 0.73, 95% CI 0.58–0.93; p = 0.01), compared with first-line IFN-β/GA therapy. Confirmed disability progression and area under the Expanded Disability Status Scale–time curve analyses were not significant. Similar relapse and treatment persistence results were observed in each of the higher disease activity subgroups. Conclusions: This study provides Class IV evidence that first-line natalizumab for RRMS improves relapse and treatment persistence outcomes compared to first-line IFN-β/GA. This needs to be balanced against the risk of progressive multifocal leukoencephalopathy in natalizumab-treated patients. Classification of evidence: This study

    Introduction First-line antiretroviral therapy (ART) failure often results from the development of resistance-associated mutations (RAMs). Three patterns, including thymidine analogue mutations (TAMs), 69 Insertion (69Ins) and the Q151M complex, are associated with resistance to multiple-nucleoside reverse transcriptase inhibitors (NRTIs) and may compromise treatment options for second-line ART. Methods We investigated patterns and factors associated with multi-NRTI RAMs at first-line failure in patients from The TREAT Asia Studies to Evaluate Resistance – Monitoring study (TASER-M), and evaluated their impact on virological responses at 12 months after switching to second-line ART. RAMs were compared with the IAS-USA 2013 mutations list. We defined multi-NRTI RAMs as the presence of either Q151M; 69Ins; ≥2 TAMs; or M184V+≥1 TAM. Virological suppression was defined as viral load (VL) <400 copies/ml at 12 months from switch to second-line. Logistic regression was used to analyze (1) factors associated with multi-NRTI RAMs at first-line failure and (2) factors associated with virological suppression after 12 months on second-line. Results A total of 105 patients from 10 sites in Thailand, Hong Kong, Indonesia, Malaysia and Philippines were included. There were 97/105 (92%) patients harbouring ≥1 RAMs at first-line failure, 39/105 with multi-NRTI RAMs: six with Q151M; 24 with ≥2 TAMs; and 32 with M184V+≥1 TAM. Factors associated with multi-NRTI RAMs were CD4 ≤200 cells/µL at genotyping (OR=4.43, 95% CI [1.59–12.37], p=0.004) and ART duration >2 years (OR=6.25, 95% CI [2.39–16.36], p<0.001). Among 87/105 patients with available VL at 12 months after switch to second-line ART, virological suppression was achieved in 85%. The median genotypic susceptibility score (GSS) for the second-line regimen was 2.00. Patients with ART adherence ≥95% were more likely to be virologically suppressed (OR=9.33, 95% CI (2.43–35.81), p=0.001). Measures of patient

    The aim of this paper is to examine health care organizations' power structures from the first-line management perspective. What liable power structures derive from the theoretical bases of bureaucratic, professional and result based organizations, and what power type do health care organizations represent, according to the empirical data? The paper seeks to perform an analysis using Mintzberg's power configurations of instrument, closed system, meritocracy and political arena. The empirical study was executed at the end of 2005 through a survey in ten Finnish hospital districts in both specialized and primary care. Respondents were all first-line managers in the area and a sample of staff members from internal disease, surgical and psychiatric units, as well as out-patient and primary care units. The number of respondents was 1,197 and the response percentage was 38. The data were analyzed statistically. As a result, it can be seen that a certain kind of organization structure supports the generation of a certain power type. A bureaucratic organization generates an instrument or closed system organization, a professional organization generates meritocracy and also political arena, and a result-based organization has a connection to political arena and meritocracy. First line managers regarded health care organizations as instruments when staff regarded them mainly as meritocracies having features of political arena. Managers felt their position to be limited by rules, whereas staff members regarded their position as having lots of space and influence potential. If the organizations seek innovative and active managers at the unit level, they should change the organizational structure and redistribute the work so that there could be more space for meaningful management. This research adds to the literature and gives helpful suggestions that will be of interest to those in the position of first-line management in health care.

    When patients have HIV RNA suppressed to <50 copies/ml on current treatment, switching to darunavir (DRV)/ritonavir (DRV/r) monotherapy could prevent the development of resistance to other drug classes. In the MONET trial, 256 patients with HIV RNA<50 copies/ml on current highly active antiretroviral therapy (57% with protease inhibitors [PIs] and 43% with non-nucleoside reverse transcriptase inhibitors) and no history of virological failure were randomized to DRV/r 800/100 mg once daily, either as monotherapy (monotherapy arm) or with two nucleoside reverse transcriptase inhibitors (NRTIs; triple therapy arm). All samples with HIV RNA ≥ 50 copies/ml were genotyped, and a virtual phenotype was calculated (VircoType HIV-1 assays; Virco BVBA, Mechelen, Belgium). A total of 63 patients had ≥ 1 HIV RNA result ≥ 50 copies/ml, of whom 38 were successfully genotyped. Most HIV RNA increases were transient and in the range of 50-200 copies/ml. Overall, 36 of the 38 (95%) successfully genotyped patients showed no International AIDS Society-USA major PI mutations, DRV mutations or NRTI mutations. Two patients showed some evidence of PI resistance during transient HIV RNA elevations: one patient in the monotherapy arm had a single DRV mutation (L33F) when HIV RNA was 63 copies/ml (the virus was phenotypically sensitive to DRV [fold change 0.8]) and one PI pretreated patient taking tenofovir disoproxil fumarate/emtricitabine/DRV/r had re-emergence of pre-existing NRTI (M184V) and PI (V82I and L90M) mutations after a short treatment interruption (this virus remained phenotypically sensitive to DRV/r). Both patients showed sustained HIV RNA suppression to week 48 remaining with the same treatment. Emergence of drug resistance after changing a suppressive triple antiretroviral therapy to DRV/r with or without nucleoside analogues is uncommon.

    We report the first observation of the line shape of the Λ(1405) from electroproduction, and show that it is not a simple Breit-Wigner resonance. Electroproduction of K+Λ(1405) off the proton was studied by using data from CLAS at Jefferson Lab in the range 1.0line shape. In our fits, the line shape corresponds approximately to predictions of a two-pole meson-baryon picture of the Λ(1405), with a lower mass pole near 1368 MeV/c2 and a higher mass pole near 1423 MeV/c2. Furthermore, with increasing photon virtuality the mass distribution shifts toward the higher mass pole.

    Non-small-cell lung cancer (NSCLC) is one of the leading causes of cancer deaths, both within the US and worldwide. There have been major treatment advances in NSCLC over the past decade with the discovery of molecular drivers of NSCLC, which has ushered in an era of personalized medicine. There are several actionable genetic aberrations in NSCLC, such as epidermal growth factor receptor and anaplastic lymphoma kinase (ALK). In 3%–7% of NSCLC, a chromosomal inversion event in chromosome 2 leads to fusion of a portion of the ALK gene with the echinoderm microtubule–associated protein-like 4 (EML4) gene. The constitutive activation of the ALK fusion oncogene renders it vulnerable to therapeutic intervention. This review focuses on the first-line treatment of advanced ALK-positive NSCLC using ALK inhibitors. Crizotinib was the first agent proven to be efficacious as first-line treatment for ALK-positive NSCLC. However, acquired resistance inevitably develops. The central nervous system is a sanctuary site that represents a common site for disease progression as well. Hence, more potent, selective next-generation ALK inhibitors that are able to cross the blood–brain barrier have been developed for treatment against crizotinib-resistant ALK-positive NSCLC and are also currently being evaluated for first-line therapy as well. In this review, we provide summary of the clinical experience with these drugs in the treatment of ALK-positive NSCLC. PMID:28210152

    To integrate long-term measures of disease-modifying drug efficacy and risk to guide selection of first-line treatment of multiple sclerosis. We created a Markov decision model to evaluate disability worsening and progressive multifocal leukoencephalopathy (PML) risk in patients receiving natalizumab (NTZ), fingolimod (FGL), or glatiramer acetate (GA) over 30 years. Leveraging publicly available data, we integrated treatment utility, disability worsening, and risk of PML into quality-adjusted life-years (QALYs). We performed sensitivity analyses varying PML risk, mortality and morbidity, and relative risk of disease worsening across clinically relevant ranges. Over the entire reported range of NTZ-associated PML risk, NTZ as first-line therapy is predicted to provide a greater net benefit (15.06 QALYs) than FGL (13.99 QALYs) or GA (12.71 QALYs) treatment over 30 years, after accounting for loss of QALYs due to PML or death (resulting from all causes). NTZ treatment is associated with delayed worsening to an Expanded Disability Status Scale score ≥6.0 vs FGL or GA (22.7, 17.0, and 12.4 years, respectively). Compared to untreated patients, NTZ-treated patients have a greater relative risk of death in the early years of treatment that varies according to PML risk profile. NTZ as a first-line treatment is associated with the highest net benefit across full ranges of PML risk, mortality, and morbidity compared to FGL or GA. Integrated modeling of long-term treatment risks and benefits informs stratified clinical decision-making and can support patient counseling on selection of first-line treatment options. © 2017 American Academy of Neurology.

    Artemisinin-based combination therapies (ACTs) against malaria are subsidized in many African countries, but the impact of subsidy programs in reducing the sales of concomitantly available antimalarial monotherapies is poorly defined. Data from The MENTOR initiative, that introduced subsidized artemether-lumefantrine (sAL) in the private sector of Huambo province, Angola, were used. The main response variable was represented by sales of sAL and of monotherapies, measured as number of treatment courses. Sales in private pharmacies of sAL and four antimalarial monotherapies between 2009 and 2013 were organized in four time-periods, and analyzed using generalized linear models for repeated measures. A secondary analysis evaluated changes in relative market share. We analyzed data from 34 pharmacies at four time points, taken from a larger survey that involved 165 pharmacies between June 2009 and March 2013. The sAL, following its introduction, became the dominant antimalarial treatment in the private sector, usually exceeding the total sales of all antimalarial monotherapies combined (1480/2800 total treatment courses, 52.8% of all sales in March 2013). Sales of monotherapies decreased significantly, but did not stop, representing 36.7% (1028/2800) of sales at the end of the survey. Subsidized ACTs can attain rapidly a high relative market share. Their introduction reduced, but did not eliminate the demand for less effective monotherapies, that might favor parasite resistance. © The Author 2016.

    To evaluate the efficacy and safety of switching from intravenous (IV) tocilizumab (TCZ) to subcutaneous (SC) TCZ monotherapy in rheumatoid arthritis patients. Patients who had completed 24 weeks of TCZ-SC (162 mg/2 weeks) or TCZ-IV (8 mg/kg/4 weeks) monotherapy in the double-blind period of the MUSASHI study were enrolled in an 84-week open-label extension period. All received TCZ-SC (162 mg/2 weeks) monotherapy. Effects of the IV to SC switch were evaluated at week 36 (12 weeks after switching). Overall, 319 patients received ≥1 dose of TCZ-SC during the open-label extension period; 160 switched from TCZ-IV to TCZ-SC (TCZ IV/SC) and 159 continued TCZ-SC (TCZ SC/SC). Disease Activity Score in 28 joints using the erythrocyte sedimentation rate clinical remission rates were 62.5% (100 of 160) for TCZ IV/SC and 50.0% (79 of 158) for TCZ SC/SC at week 24, and were maintained at 62.5% (100 of 160) and 57.0% (90 of 158), respectively, at week 36. In the TCZ IV/SC group, 9% of patients (9 of 100) who had achieved remission at week 24 could not maintain remission at week 36. In TCZ IV/SC patients weighing ≥70 kg, the percentage with a sufficient serum TCZ concentration (≥1 μg/ml) decreased from 90.9% (10 of 11) at week 24 to 45.5% (5 of 11) at week 36. Overall safety profiles were similar in TCZ IV/SC and TCZ SC/SC except for mild injection site reactions in TCZ IV/SC. Efficacy is adequately maintained in most patients switching from TCZ-IV (8 mg/kg/4 weeks) to TCZ-SC (162 mg/2 weeks) monotherapy. Patients receiving TCZ-IV can switch to TCZ-SC without serious safety concerns. Clinical efficacy may be reduced after switching in some patients with high body weight. © 2015 The Authors.

    Studies evaluating the effect of levetiracetam (LEV) on haematological parameters in patients with epilepsy are very limited. Clinical trials have also reported an unexplained increased incidence of pharyngitis and rhinitis in LEV-treated patients. The objective of this study was to evaluate prospectively the changes in haematological parameters in children treated with LEV monotherapy. White blood cell, neutrophils, lymphocytes, monocytes, haemoglobin, haematocrit, mean corpuscular volume, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration and platelets were measured in 22 children (13 females, mean age 6.70±4.23 years) with epilepsy, before and after 2 and 6 months of LEV monotherapy. Lymphocyte count was significantly decreased at 6 months (p=0.019) of treatment and this effect was not dose dependent. One child (4.5%) at 2 months and four children (18%) at 6 months of treatment had lymphocyte count below 10th percentile for age. There were no significant alterations in the other parameters evaluated during the study. LEV monotherapy may significantly decrease lymphocyte count at six months of treatment in children with epilepsy. Further prospective studies are needed to investigate the effect of LEV on haematological parameters and the possible association with the higher incidence of infections reported in children receiving LEV.

    Androgenetic alopecia (AGA) is the most common form of hair loss in men and in women. Currently, minoxidil and finasteride are the treatments with the highest levels of medical evidence, but patients who exhibit intolerance or poor response to these treatments are in need of additional treatment modalities. The aim was to evaluate the efficacy and safety of low-level laser therapy (LLLT) for AGA, either as monotherapy or as concomitant therapy with minoxidil or finasteride, in an office-based setting. Retrospective observational study of male and female patients with AGA, treated with the 655 nm-HairMax Laser Comb(®), in an office-based setting. Efficacy was assessed with global photographic imaging. Of 32 patients (21 female, 11 male), 8 showed significant, 20 moderate, and 4 no improvement. Improvement was seen both with monotherapy and with concomitant therapy. Improvement was observed as early as 3 months and was sustained up to a maximum observation time of 24 months. No adverse reactions were reported. LLLT represents a potentially effective treatment for both male and female AGA, either as monotherapy or concomitant therapy. Combination treatments with minoxidil, finasteride, and LLLT may act synergistic to enhance hair growth.

    This randomised, double-blind, parallel-group, phase 3 study compared monotherapy with sirukumab, an anti-interleukin-6 cytokine monoclonal antibody, with adalimumab monotherapy in patients with rheumatoid arthritis (RA). Biologic-naïve patients with active RA who were inadequate responders or were intolerant to, or inappropriate for, methotrexate were randomised to subcutaneous sirukumab 100 mg every 2 weeks (n=187), sirukumab 50 mg every 4 weeks (n=186) or adalimumab 40 mg every 2 weeks (n=186). Primary endpoints at week 24 were change from baseline in Disease Activity Score in 28 joints (DAS28) using erythrocyte sedimentation rate (ESR) and proportion of patients achieving an American College of Rheumatology (ACR) 50 response; these endpoints were tested in sequential order. This study is registered at EudraCT (number: 2013-001417-32) and ClinicalTrials.gov (number: NCT02019472). Significantly greater improvements from baseline in mean (SD) DAS28 (ESR) were observed at week 24 with sirukumab 100 mg every 2 weeks (-2.96 (1.580)) versus adalimumab 40 mg every 2 weeks (-2.19 (1.437); P<0.001). Sirukumab 50 mg every 4 weeks also showed significantly greater improvement from baseline at week 24 in DAS28 (ESR) (-2.58 (1.524)) compared with adalimumab (P=0.013). The ACR50 response rates with the 100 mg (35.3%) and 50 mg (26.9%) doses of sirukumab were comparable to that with adalimumab (31.7%) at week 24. The safety profile of sirukumab was consistent with that observed with anti-interleukin-6 receptor antibodies. A dose-related effect on the incidence of injection-site reactions was observed with sirukumab. Sirukumab monotherapy showed greater improvements in DAS28 (ESR), but similar ACR50 response rates, versus adalimumab monotherapy. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

  3. Slim by design: serving healthy foods first in buffet lines improves overall meal selection.

    Each day, tens of millions of restaurant goers, conference attendees, college students, military personnel, and school children serve themselves at buffets--many being all-you-can-eat buffets. Knowing how the food order at a buffet triggers what a person selects could be useful in guiding diners to make healthier selections. The breakfast food selections of 124 health conference attendees were tallied at two separate seven-item buffet lines (which included cheesy eggs, potatoes, bacon, cinnamon rolls, low-fat granola, low-fat yogurt, and fruit). The food order between the two lines was reversed (least healthy to most healthy, and vise-versa). Participants were randomly assigned to choose their meal from one line or the other, and researchers recorded what participants selected. With buffet foods, the first ones seen are the ones most selected. Over 75% of diners selected the first food they saw, and the first three foods a person encountered in the buffet comprised 66% of all the foods they took. Serving the less healthy foods first led diners to take 31% more total food items (p<0.001). Indeed, diners in this line more frequently chose less healthy foods in combinations, such as cheesy eggs and bacon (r = 0.47; p<0.001) or cheesy eggs and fried potatoes (r= 0.37; p<0.001). This co-selection of healthier foods was less common. Three words summarize these results: First foods most. What ends up on a buffet diner's plate is dramatically determined by the presentation order of food. Rearranging food order from healthiest to least healthy can nudge unknowing or even resistant diners toward a healthier meal, helping make them slim by design. Health-conscious diners, can proactively start at the healthier end of the line, and this same basic principle of "first foods most" may be relevant in other contexts - such as when serving or passing food at family dinners.

    With a high prevalence of chronic kidney disease (CKD) in type 2 diabetes (T2DM) in Thailand, the appropriate treatment for the patients has become a major concern. This study aimed to evaluate long-term cost-effective of dipeptidyl peptidase-4 (DPP-4) inhibitor monothearpy vs sulfonylurea (SFU) monotherapy in people with T2DM and CKD. A validated IMS CORE Diabetes Model was used to estimate the long-term costs and outcomes. The efficacy parameters were identified and synthesized using a systematic review and meta-analysis. Baseline characteristics and cost parameters were obtained from published studies and hospital databases in Thailand. Costs were expressed in 2014 US Dollars. Outcomes were presented as an incremental cost-effectiveness ratio (ICER). One-way and probabilistic sensitivity analyses were performed to estimate parameter uncertainty. From a societal perspective, treatment with DPP-4 inhibitors yielded more quality-adjusted life years (QALYs) (0.024) at a higher cost (>66,000 Thai baht (THB) or >1,829.27 USD) per person than SFU, resulting in the ICER of >2.7 million THB/QALY (>74,833.70 USD/QALY). The cost-effectiveness results were mainly driven by differences in HbA1c reduction, hypoglycemic events, and drug acquisition cost of DPP-4 inhibitors. At the ceiling ratio of 160,000 THB/QALY (4,434.59 USD/QALY), the probability that DPP-4 inhibitors are cost-effective compared to SFU was less than 10%. Compared to SFU, DPP-4 inhibitor monotherapy is not a cost-effective treatment for people with T2DM and CKD in Thailand.

    The aim of this study was to describe first-line managers' experiences of alternative modes of funding elderly care in two communities in western Sweden. A growing elderly population demands alternative modes of funding elderly care for better outcomes for patients and better efficiency as it is publicly funded through taxation. The study comprised a total of eight semi-structured interviews with first-line managers working within elderly care. The interviews were analysed using manifest qualitative content analysis. Respect for the individuals was a main concern in the study. One category, quality improvement, and four subcategories freedom of choice, organisational structure, quality awareness and market forces effects were identified to describe first-line managers' experiences of the operation of elderly care. Quality improvement was an important factor to deal with when elderly care was operated in different organisational perspectives, either private or public. The first-line manager is a key person for developing a learning organisation that encourages both staff, clients and their relatives to improve the organisation. Moreover, person-centred care strengthens the client's role in the organisation, which is in line with the government's goal for the quality improvement of elderly care. However, further research is needed on how quality improvement could be developed when different caregivers operate in the same market in order to improve care from the elderly perspective. This study highlights alternative modes of funding elderly care. The economical perspectives should not dominate without taking care of quality improvement when the operation of elderly care is planned and implemented. Strategies such as a learning organisational structure built on person-centred care could create quality improvement in elderly care. © 2012 Blackwell Publishing Ltd.

    A puerperal vulvovaginal hematoma may continue to grow after a surgical procedure and may require blood transfusion. Thus, we selected arterial embolization for hemostasis as the first-line management in two cases of large vulvovaginal hematoma. Case 1 was a 32-year-old pregnant woman. After delivery, a 10-cm vulvar hematoma developed. An enhanced computed tomography (CT) scan revealed active bleeding. Arterial embolization was performed and complete hemostasis was obtained. Case 2 was a 34-year-old woman with a recurring hematoma after delivery. An enhanced CT scan revealed extravasation in the hematoma. Gelatin sponges were applied and complete hemostasis was obtained. In both cases, arterial embolization was successful without requiring blood transfusions. We successfully managed two cases of puerperal vulvovaginal hematoma by arterial embolization based on the evaluation of an enhanced CT scan. In conclusion, we suggest arterial embolization to be a viable option for first-line treatment in the management of vulvovaginal hematomas. Copyright © 2017. Published by Elsevier B.V.

    To determine the maximum tolerated dose (MTD), dose-limiting toxicity (DLT) and efficacy of sorafenib in combination with FOLFOX4 (oxaliplatin/leucovorin (LV)/5-fluorouracil) as first-line treatment for advanced gastric cancer, we performed a phase I dose-finding study in nine evaluable patients with unresectable locally advanced or metastatic gastric cancer or gastroesophageal junction adenocarcinoma. According to modified Fibonacci method, the design of this study was to guide elevation of the sorafenib dosage to the next level (from 200 mg twice daily to 400 mg twice daily and then, if tolerated, 600 mg twice daily). If the patient achieved complete response (CR), partial response (PR) or stable disease (SD) after eight cycles of treatment, combination chemotherapy was scheduled to be discontinued and sorafenib monotherapy continued at the original dose until either disease progression or unacceptable toxicity. In sorafenib 200 mg twice daily group, DLT was observed in 1 of 6 patients, and in 400 mg twice daily group, it was observed in 2 of 3 patients. Seven of 9 (77.8%) evaluable patients achieved PR, with a median overall survival (OS) of 11.8 [95% confidence interval (CI): 8.9-14.7] months. Common adverse effects include hand-foot syndrome, leukopenia, neutropenia, anorexia, and nausea. Twice-daily dosing of sorafenib 200 mg in combination with FOLFOX4 was proven effective and safe for the treatment of advanced gastric cancer, and could be an appropriate dosage for subsequent phase II clinical studies.

    Movement of the grounding line (i.e, the line between the grounded and the floating part of a marine ice-sheet) is one of the key processes that governs the mass balance of marine ice-sheets. So far, modeling of grounding line migration was inconsistent, leading to poorly reliable forecast of marine ice-sheet evolution. Important theoretical progress has been made these last years to describe the dynamics of the grounding line, and a recently developed full-Stokes model gives consistent results in comparison to this theory. Despite these important breakthroughs, theory as well as the model are restricted to two-dimensional flow line and therefore unable to be applied to a particular three-dimensional glaciological problem. Nevertheless, some first insights can be already drawn from 2D modeling results to improve the adequacy between future modeling and field measurements. We will particularly emphasize on two different aspects. (i) Modeling results have shown the major importance of high grid resolution in the vicinity of the grounding line, questioning strategies for future measurement campaigns of bedrock elevation of coastal glaciers. (ii) An approximately 10 m depression of the surface at the vertical position above the grounding line is a very stable feature produced by the model. Careful investigation of the surface curvature should help to locate grounding line position.

    Guidelines propose additional therapy to statin to treat elevated triglycerides (TG) and low high-density lipoprotein cholesterol (HDLC) in dyslipidemic patients. We evaluated the effects of new fixed-dose combinations (FDC) of fenofibrate/simvastatin on plasma lipids versus simvastatin or fenofibrate monotherapies. Subjects with mixed dyslipidemia at high or very high cardiovascular risk on stable statin therapy for at least 3 months were included in a randomized, double-blind, active-control, parallel-group study. Patients were treated with FDC fenofibrate/simvastatin 145/20 mg or 145/40 mg, simvastatin 20 mg or 40 mg, or fenofibrate 145 mg for 12 weeks. Plasma lipids, C-reactive protein, and cystatin C were measured before and after treatments. Differences in % changes were compared between FDC fenofibrate/simvastatin and monotherapies. Significant differences between FDC fenofibrate/simvastatin and simvastatin monotherapies were observed for the % change of TG (LS mean difference [two-sided 95% CI]: -32.2% [-38.6%, -25.8%], P < 0.001) and HDL-C (7.5% [4.7%, 10.2%], P < 0.001). A significant difference between the FDC fenofibrate/simvastatin and fenofibrate was observed for LDLC % changes (-34.7% [-40.8%, -28.5%], P < 0.001). Significant differences between FDC fenofibrate/simvastatin and their respective monotherapies were also observed for Apo B and non-HDLC % changes. The FDC were well tolerated with a similar safety profile compared with monotherapies. FDC fenofibrate/simvastatin are effective and well-tolerated therapies to improve the TG and HDLC profile in high-risk patients with mixed dyslipidemia. © 2015 John Wiley & Sons Ltd.

    OBJECTIVE Postoperative seizures are a common complication in patients undergoing an awake craniotomy, given the cortical manipulation during tumor resection and the electrical cortical stimulation for brain mapping. However, little evidence exists about the efficacy of postoperative seizure prophylaxis. This study aims to determine the most appropriate antiseizure drug (ASD) management regimen following an awake craniotomy. METHODS The authors performed a retrospective analysis of data pertaining to patients who underwent an awake craniotomy for brain tumor from 2007 to 2015 performed by a single surgeon. Patients were divided into 2 groups, those who received a single ASD (the monotherapy group) and those who received 2 types of ASDs (the duotherapy group). Patient demographics, symptoms, tumor characteristics, hospitalization details, and seizure outcome were evaluated. Multivariable logistic regression was used to evaluate numerous clinical variables associated with postoperative seizures. RESULTS A total of 81 patients underwent an awake craniotomy for tumor resection of an eloquent brain lesion. Preoperative baseline characteristics were comparable between the 2 groups. The postoperative seizure rate was 21.7% in the monotherapy group and 5.7% in the duotherapy group (p = 0.044). Seizure outcome at 6 months' follow-up was assessed with the Engel classification scale. The duotherapy group had a significantly higher proportion of seizure-free (Engel Class I) patients than the monotherapy group (90% vs 60%, p = 0.027). The length of stay was similar, 4.02 days in the monotherapy group and 4.51 days in the duotherapy group (p = 0.193). The 90-day readmission rate was higher for the monotherapy group (26.1% vs 8.5% in the duotherapy group, p = 0.044). Multivariate logistic regression showed that preoperative seizure history was a significant predictor for postoperative seizures following an awake craniotomy (OR 2.08, 95% CI 0.56-0.90, p < 0.001).

    The combination of paclitaxel + ramucirumab is a standard second-line treatment in patients with advanced gastric cancer. This therapy has been associated with increased median overall survival and progression-free survival compared with those with paclitaxel monotherapy. We evaluated the cost-effectiveness of paclitaxel + ramucirumab combination therapy in patients with advanced gastric cancer, from the perspective of health care payers in Japan. We constructed a Markov model to compare, over a time horizon of 3 years, the costs and effectiveness of the combination of paclitaxel + ramucirumab and paclitaxel alone as second-line therapies for advanced gastric cancer in Japan. Health outcomes were measured in life-years (LYs) and quality-adjusted (QA) LYs gained. Costs were calculated using year-2016 Japanese yen (¥1 = US $17.79) according to the social insurance reimbursement schedule and drug tariff of the fee-for-service system in Japan. Model robustness was addressed through 1-way and probabilistic sensitivity analyses. The costs and QALYs were discounted at a rate of 2% per year. The willingness-to-pay threshold was set at the World Health Organization's criterion of ¥12 million, because no consensus exists regarding the threshold for acceptable cost per QALY ratios in Japan's health policy. Paclitaxel + ramucirumab combination therapy was estimated to provide an additional 0.09 QALYs (0.10 LYs) at a cost of ¥3,870,077, resulting in an incremental cost-effectiveness ratio of ¥43,010,248/QALY. The incremental cost-effectiveness ratio for the combination therapy was >¥12 million/QALY in all of the 1-way and probabilistic sensitivity analyses. Adding ramucirumab to a regimen of paclitaxel in the second-line treatment of advanced gastric cancer is expected to provide a minimal incremental benefit at a high incremental cost per QALY. Based on our findings, adjustments in the price of ramucirumab, as well as improves in other clinical parameters such as survival

    A high genetic resistance barrier to the integrase-strand-transfer-inhibitor (INSTI) dolutegravir has been reported in vitro and in vivo. We describe the dynamics of INSTI-resistance-associated-mutations (INSTI-RAMs) and mutations in the 3'-polypurine tract (3'-PPT) in relation to virological failure (VF) observed in the randomized dolutegravir maintenance monotherapy study (DOMONO, NCT02401828). From ten patients with VF plasma samples prior to start cART and during VF were used to generate Sanger sequences of integrase, the 5' terminal bases of the 3'- LTR, and the 3'-PPT. Median HIV-RNA (IQR) at VF was 3,490 (1,440-4,990) c/mL. INSTI-RAMs were detected in 4/10 patients (S230R, R263K, N155H, E92Q+N155H) and in 4/10 patients no INSTI-RAMs were detected (2/10 patients integrase sequencing was unsuccessful). The time-to-VF ranged from 4 weeks to 72 weeks. In one patient, mutations developed in the highly conserved 3'-PPT. No changes in the terminal bases of the 3'-LTR were observed. The genetic barrier to resistance is too low to justify dolutegravir maintenance monotherapy as single INSTI-RAMs are sufficient to cause VF. The large variation in time-to-VF suggests that stochastic reactivation of a pre-existing provirus containing a single INSTI-RAM is the mechanism for failure. Changes in the 3'-PPT point to a new dolutegravir resistance mechanism in vivo.

    Patients with hematological disorders develop febrile neutropenia (FN); most of these events remain undetermined in origin. We performed a prospective study to determine the microbiological characteristics of infections and their response to the first-line antibiotic therapy in FN. The study was conducted at National Institute of Blood Disease and Bone Marrow Transplant. Two-hundred episodes of FN were assessed for the bacterial growth, antimicrobial susceptibility pattern and response to the first-line treatment of FN. All patients were given Ceftazidime and Amikacin Bosch Pharmaceutical (Pvt. Ltd), as first-line antibiotic in FN. Out of 200 episodes we had 108 clinically and microbiologically documented infections. The isolated frequencies for gram negative and gram positive organisms were n = 52 and 49 (48 and 45 %) respectively. Among gram negative micro-organisms, Escherichia coli (E. coli) was isolated in 15 (28.8 %), Klebsiella pneumonae in 4 (7.6 %) and Pseudomonas aeruginosa in 10 (19.2 %) were in highest frequencies. Methicillin sensitive staphylococci emerged as the frequently isolated gram-positive bacteria. Eight-one episodes (45.3 %) responded to the first-line treatment and death reported in 20 cases (10 %). Our study showed almost equal trend of gram positive and gram negative bacteria isolated from patients suffering from neutropenic fever. Empirical use of Ceftazidime and Amikacin as first-line antibiotics was able to cover the infection only in 45.3 % of episodes suffering from FN.

    Venetoclax (Venclexta™) is an oral selective inhibitor of the prosurvival protein BCL-2 and therefore restores the apoptotic ability of malignant cells. The drug arose from research by Abbott Laboratories (now AbbVie) during a collaboration with Genentech and is being co-developed by AbbVie and Genentech/Roche primarily for the treatment of haematological malignancies. Venetoclax is approved in the USA for use as monotherapy in patients with chronic lymphocytic leukaemia (CLL) with the 17p deletion (as detected by an approved FDA test) who have received at least one prior therapy, and is awaiting approval for similar indications in the EU and Canada. Venetoclax is also in phase I-III development as combination therapy for CLL, phase I/II development as monotherapy and/or combination therapy for non-Hodgkin lymphomas (including diffuse large B-cell lymphoma, mantle cell lymphoma, follicular lymphoma) and acute myeloid leukaemia, and phase I development for multiple myeloma, systemic lupus erythematosus and breast cancer. This article summarizes the milestones in the development of venetoclax leading to this first approval for CLL.

    S-1 is an oral fluoropyrimidine that is active in the treatment of non-small cell lung cancer (NSCLC); however, an optimal treatment schedule and appropriate dose adjustments of S-1 in elderly patients have not yet been established. We conducted a phase II trial to evaluate the efficacy and safety of a 2-week S-1 monotherapy treatment followed by a 1-week interval as a first-line treatment of elderly NSCLC patients, by adjusting the dose based on the individual creatinine clearance (Ccr) and body surface area (BSA). The primary endpoint was the disease control rate. Forty patients were enrolled. The disease control and response rates were 89.5% (95% confidence interval [CI] = 79.8-99.2) and 7.9% (95% CI = 0.0-16.4), respectively. The median progression-free survival and overall survival times were 4.4 months (95% CI = 4.2-8.5) and 17.0 months (95% CI = 11.2-18.7), respectively. Neutropenia, anorexia, hyponatremia, hypokalemia, and pneumonia of grade ≥ 3 occurred in 5.0%, 7.5%, 5.0%, 2.5%, and 2.5% of patients, respectively. Among the patient-reported outcomes, most of the individual factors in the patients' quality of life, including upper intestine-related symptoms improved with the treatment, except for dyspnea, which slightly albeit continuously worsened throughout the study. In elderly patients with previously untreated advanced NSCLC, a 2-week S-1 monotherapy treatment, tailored to both the Ccr and BSA, with a 1-week interval was well tolerated and demonstrated promising efficacy.

    To address the information gap on current use of antiretroviral drugs (ARTs) in developing countries. The AIDS Medicines and Diagnostics Service of the World Health Organization (WHO) carried out a multi-country survey in early 2006. Questionnaires covered the use of first- and second-line regimens in adults and children, and the rates of switching from first-line to second-line regimen. Weighted percentages of use of ARTs across the cohort of adults and children were calculated and correlated with 2006 WHO guidelines. A second analysis compared demand for ARTs with rates of production of active pharmaceutical ingredients. Twenty-three countries (96%) returned the questionnaires, representing 53% of relevant patients in developing countries as of June 2006, and comprising 92% adults and 8% children receiving ARTs. Response rates were highest for questions regarding first-line use and lowest for those regarding pediatric regimens. The distribution of first-line: second-line use was 96%: 4% among adults and 99%: 1% among children. For adults, 95% of those receiving first-line treatment, but only 25% of those receiving second-line treatment, were on regimens consistent with those preferred by the WHO. Among first-line users, the most common regimen (61%) was stavudine+lamivudine+nevirapine. Among second-line users, abacavir+didanosine+lopinavir/ritonavir was the most common regimen (24%). Among children, compliance with WHO guidelines was high among the respondents, with zidovudine+lamivudine+nevirapine reported as the main option. Estimates of first-year switching rate were highly variable, ranging from 1% to 15%, with only ten responses. Comparison of supply and demand showed that the stated production capacity for active pharmaceutical ingredients is sufficient to meet current demands for ARTs. This survey has provided valuable information on the uptake of ARTs in developing countries and will help forecast future demand. Reporting for second-line and pediatric

    We conducted this meta-analysis to systematically review and analyze the clinical benefits of angiotensin receptor blocker (ARB) combined with calcium channel blocker (CCB) following ineffective CCB monotherapy. PubMed was searched for articles published until August 2015. Randomized controlled trials (RCTs) evaluating the clinical benefits of ARB combined with CCB following ineffective CCB monotherapy were included. The primary efficacy endpoint of the studies was normal rate of blood pressure, the secondary efficacy endpoints were the response rate and change in blood pressure from baseline. The safety endpoint of the studies was incidence of adverse events. Differences are expressed as relative risks (RRs) with 95% confidence intervals (CIs) for dichotomous outcomes and weighted mean differences (WMDs) with 95% CIs for continuous outcomes. Heterogeneity across studies was tested by using the I(2) statistic. Seven RCTs were included and had sample sizes ranging from 185 to 1,183 subjects (total: 3,909 subjects). The pooled analysis showed that the on-target rate of hypertension treatment was significantly higher in the amlodipine + ARB group than in the amlodipine monotherapy group (RR =1.59; 95% CI, 1.31-1.91; P<0.01). The response rate of systolic blood pressure (SBP) (RR =1.28; 95% CI, 1.04-1.58; P<0.01) and diastolic blood pressure (DBP) (RR =1.27; 95% CI, 1.12-1.44; P=0.04) were significantly higher in the amlodipine + ARB group than in the amlodipine monotherapy group. The change in SBP (RR =-3.56; 95% CI, -7.76-0.63; P=0.10) and DBP (RR =-3.03; 95% CI, -6.51-0.45; P=0.09) were higher in hypertensive patients receiving amlodipine + ARB but the difference did not reach statistical significance. ARB + amlodipine treatment carried a lower risk of adverse events relative to amlodipine monotherapy (RR =0.88; 95% CI, 0.80-0.96; P<0.01). The results of our meta-analysis demonstrate that adding an ARB to CCB after initial ineffective CCB monotherapy, significantly

    We have made the first detections of the 88 micrometers [O(sub III)] line from galaxies in the early universe, detecting the line from the lensed active galactic nucleus (AGN)/starburst composite systems APM 08279+5255 at z 3.911 and SMM J02399-0136 at z = 2.8076. The line is exceptionally bright from both systems, with apparent (lensed) luminosities approx.10(exp 11) Solar Luminosity, For APM 08279, the [O(sub III)] line flux can be modeled in a star formation paradigm, with the stellar radiation field dominated by stars with effective temperatures, T(sub eff) > 36,000 K, similar to the starburst found in M82. The model implies approx.35% of the total far-IR luminosity of the system is generated by the starburst, with the remainder arising from dust heated by the AGN. The 881,tm line can also be generated in the narrow-line region of the AGN if gas densities are around a few 1000 cu cm. For SMM J02399, the [O(sub III)] line likely arises from HII regions formed by hot (T(sub eff) > 40,000 K) young stars in a massive starburst that dominates the far-IR luminosity of the system. The present work demonstrates the utility of the [O(sub III)] line for characterizing starbursts and AGN within galaxies in the early universe. These are the first detections of this astrophysically important line from galaxies beyond a redshift of 0.05.s

    Background The number of people living with HIV on antiretroviral treatment (ART) in Myanmar has been increasing rapidly in recent years. This study aimed to estimate rates of virological failure on first-line ART and switching to second-line ART due to treatment failure at the Integrated HIV Care program (IHC). Methods Routinely collected data of all adolescent and adult patients living with HIV who were initiated on first-line ART at IHC between 2005 and 2015 were retrospectively analyzed. The cumulative hazard of virological failure on first-line ART and switching to second-line ART were estimated. Crude and adjusted hazard ratios were calculated using the Cox regression model to identify risk factors associated with the two outcomes. Results Of 23,248 adults and adolescents, 7,888 (34%) were tested for HIV viral load. The incidence rate of virological failure among those tested was 3.2 per 100 person-years follow-up and the rate of switching to second-line ART among all patients was 1.4 per 100 person-years follow-up. Factors associated with virological failure included: being adolescent; being lost to follow-up at least once; having WHO stage 3 and 4 at ART initiation; and having taken first-line ART elsewhere before coming to IHC. Of the 1032 patients who met virological failure criteria, 762 (74%) switched to second-line ART. Conclusions We found high rates of virological failure among one third of patients in the cohort who were tested for viral load. Of those failing virologically on first-line ART, about one quarter were not switched to second-line ART. Routine viral load monitoring, especially for those identified as having a higher risk of treatment failure, should be considered in this setting to detect all patients failing on first-line ART. Strategies also need to be put in place to prevent treatment failure and to treat more of those patients who are actually failing. PMID:28182786

    The present study investigated the treatment effect of dexamethasone implant (Ozurdex®, group 1) and anti-VEGF injection (Lucentis®, group 2) in course of macular oedema due to retinal vein occlusion in a retrospective, non-randomised case series. Group 1 comprised 60 patients (31 with CRVO and 29 with BRVO) and group 2 included 52 patients, 27 with CRVO and 25 with BRVO) and both groups were further treated in case of recurrence. Preoperative and in monthly intervals best corrected visual acuity (BCVA), central retinal thickness using SD-OCT (Spectralis, Heidelberg Engineering), intraocular pressure, biomicroscopy status and a fundus photo documentation (Optomap) were evaluated. The primary clinical endpoint was visual acuity 12 months after the first intravitreal therapy, while secondary endpoints included the central retinal thickness change and safety of therapy. In group 1, an increase of BCVA (± standard deviation) of 8.4 (± 1.9) letters was observed in CRVO patients and a gain of 10.7 (± 3.8) letters in BRVO patients after 12 months, while in group 2, an increase of BCVA of 6.9 (± 1.9) letters (CRVO) compared to 12.5 (± 3.7) letters (BRVO) was observed after the same time span. In both groups a significant reduction in retinal thickness was achieved. An increase of intraocular pressure above 5 mmHg was observed in nearly half of the cases In group 1, but was well controlled by conservative antiglaucomatous therapy. We observed a progression of lens opacity in approximately 50 % of the cases in group 1. The treatment with Ozurdex compared to Lucentis appears to provide a trend towards a better although not significant visual acuity increase after 12 months in CRVO patients. A similar trend favouring anti-VEGF treatment with Lucentis was seen in patients with BRVO. However, the lens status and age of the patient should be taken into account when considering a treatment with Ozurdex. Georg Thieme Verlag KG Stuttgart · New York.

    We conducted a cost-effectiveness analysis incorporating recent phase III clinical trial (FIRE-3) data to evaluate clinical and economic tradeoffs associated with first-line treatments of KRAS wild-type (WT) metastatic colorectal cancer (mCRC). A cost-effectiveness model was developed using FIRE-3 data to project survival and lifetime costs of FOLFIRI plus either cetuximab or bevacizumab. Hypothetical KRAS-WT mCRC patients initiated first-line treatment and could experience adverse events, disease progression warranting second-line treatment, or clinical response and hepatic metastasectomy. Model inputs were derived from FIRE-3 and published literature. Incremental cost-effectiveness ratios (ICERs) were reported as US$ per life year (LY) and quality-adjusted life year (QALY). Scenario analyses considered patients with extended RAS mutations and CALGB/SWOG 80405 data; 1-way and probabilistic sensitivity analyses were conducted. Compared with bevacizumab, KRAS-WT patients receiving first-line cetuximab gained 5.7 months of life at a cost of $46,266, for an ICER of $97,223/LY ($122,610/QALY). For extended RAS-WT patients, the ICER was $77,339/LY ($99,584/QALY). Cetuximab treatment was cost-effective 80.3% of the time, given a willingness-to-pay threshold of $150,000/LY. Results were sensitive to changes in survival, treatment duration, and product costs. Our analysis of FIRE-3 data suggests that first-line treatment with cetuximab and FOLFIRI in KRAS (and extended RAS) WT mCRC patients may improve health outcomes and use financial resources more efficiently than bevacizumab and FOLFIRI. This information, in combination with other studies investigating comparative effectiveness of first-line options, can be useful to clinicians, payers, and policymakers in making treatment and resource allocation decisions for mCRC patients.

    Biologic drugs are usually prescribed as second-line treatment for psoriasis, that is, after the patient has first been treated with a conventional psoriasis drug. There are, however, cases where, depending on the characteristics of the patient or the judgement of the physician, biologics may be chosen as first-line therapy. No studies to date have analyzed the demographics or clinical characteristics of patients in this setting or the safety profile of the agents used. The main aim of this study was to characterize these aspects of first-line biologic therapy and compare them to those observed for patients receiving biologics as second-line therapy. We conducted an observational study of 181 patients treated in various centers with a systemic biologic drug as first-line treatment for moderate to severe psoriasis between January 2008 and November 2016. All the patients were registered in the Spanish Registry of Adverse Events Associated with Biologic Drugs in Dermatology. The characteristics of the first- and second-line groups were very similar, although the patients receiving a biologic as first-line treatment for their psoriasis were older. No differences were observed for disease severity (assessed using the PASI) or time to diagnosis. Hypertension, diabetes, and liver disease were all more common in the first-line group. There were no differences between the groups in terms of reasons for drug withdrawal or occurrence of adverse effects. No major differences were found between patients with psoriasis receiving biologic drugs as first- or second-line therapy, a finding that provides further evidence of the safety of biologic therapy in patients with psoriasis.

    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

    The emergence of novel drugs corresponds with the determination of the effectiveness of the current treatments used in clinical practice. A retrospective observational study was conducted to evaluate the effectiveness of first-line treatments and to test the influence of the prognostic factors established using the Memorial Sloan-Kettering Cancer Center (MSKCC) and the analysis of Mekhail’s study for two or more metastatic sites. The primary endpoints were median progression-free survival (mPFS) and median overall survival (mOS) times. A total of 65 patients were enrolled and the mPFS and mOS of the patients treated with sunitinib (n=51) were 9.0 and 20.1 months, respectively, and for the patients treated with temsirolimus (n=14) these were 3.0 and 6.2 months, respectively. In the poor-prognosis (PP) group, a difference of 1.2 months (P=0.049) was found in mPFS depending on the first-line treatment. A difference of 4.1 months (P=0.023) was also found in mPFS when classified by histology (clear verses non-clear cell) in the sunitinib-treatment group. When stratified by the prognostic group, differences of >7 months (P<0.001) were found between the groups. Therefore, it was concluded that the effectiveness of the treatments was reduced compared to previous studies and differences were found in the PP group when classified by first-line drug and histology. Additionally, the influence of prognostic factors on OS and the value of stratifying patients using these factors have been confirmed. PMID:25279217

    Increasing the dose or adding a second antihypertensive agent are 2 possible therapeutic choices when blood pressure (BP) is poorly controlled with monotherapy. This study investigated the effectiveness and tolerability of barnidipine 10 or 20 mg added to losartan 50 mg versus losartan 100 mg alone in patients with mild to moderate essential hypertension whose BP was uncontrolled by losartan 50-mg monotherapy. This was a 12-week, multicenter, randomized, open-label, parallel-group study. Eligible patients (aged 30-74 years) had uncontrolled hypertension, defined as office sitting diastolic BP (DBP) > or =90 mm Hg and/or systolic BP (SBP) > or =140 mm Hg, and mean daytime DBP > or =85 mm Hg and/or SBP > or =135 mm Hg. All were being treated with losartan 50 mg at enrollment. After a 1-week run-in period while taking losartan 50 mg, patients were randomly assigned to 6 weeks of treatment with open-label barnidipine 10 mg plus losartan 50 mg or losartan 100-mg monotherapy. At the end of this period, patients with uncontrolled BP had barnidipine doubled to 20 mg and continued for an additional 6 weeks, whereas patients not achieving control on treatment with losartan 100 mg were discontinued. Office BP was measured at each visit, whereas 24-hour ambulatory BP monitoring (ABPM) was performed at randomization and at the final visit (ie, after 12 weeks of treatment, or at 6 weeks for patients not controlled on losartan 100 mg). The intent-to-treat population included all randomized patients who received at least one dose of study treatment and had valid ABPM recordings at baseline and the final visit. The primary end point was the change in daytime DBP between baseline and 12 weeks of treatment, compared between the combination treatment and monotherapy. Adverse events (AEs) were evaluated during each study visit. A total of 93 patients were enrolled (age range, 30-75 years; 60% [56/93] men). After the 1-week run-in period, 68 patients were randomly assigned to 6 weeks of

    Objective Treatment failures in advanced lung cancer are frequent events affecting patients during or after first-line chemotherapy. International guidelines recommend second-line chemotherapy. However, around one half of patients who experience disease progression enter a systemic second-line therapy. In the herein qualitative study, we investigated patients' thoughts and attitudes determining the decision to undergo a second-line chemotherapy. Methods Thirty-three purposively selected patients who recently accepted second-line or palliative chemotherapy were invited to participate in this survey consisting of semi-structured in-depth interviews. Grounded theory was applied to investigate participants’ perceptions of the context that have surrounded their decision to undergo palliative chemotherapy. Results For most patients, tumor burden and reduced quality of life in relation with lung cancer itself were major drivers of the decision-making process. There was a balance between two different attitudes: making a decision to undergo a new line of chemotherapy or starting a psychological process in order to accept end of life. Choosing between these two attitudes allowed the patient to keep the matter of palliative care at a distance. Even in case of low chance of success, many patients who worried about their life partner's future would accept a new chemotherapy line. Some patients experienced ambivalent thoughts regarding social network, particularly about their family as daily function impairment required an increased need for relative's support. The initial "Worrying about others" thoughts left place to in an increasing self-need of care as those provided by relatives; this phenomenon might increase patients' self- perception of being a burden for others. Confidence previously established with formal caregiver support was another major decision driver: some patients with sustained confidence in their medical staff may have privileged this formal support rather

    VEGF driven angiogenesis plays a key role in cancer progression. We determined the clinical efficacy of bevacizumab monotherapy in patients with metastatic melanoma. Thirty-five patients with metastatic melanoma in progression were enrolled in this phase II, single arm clinical trial. Each patient received bevacizumab monotherapy 10 mg/kg q14 d until intolerable toxicity or disease progression occurred. Clinical efficacy was evaluated as objective response, disease control (DC), and survival. We observed one complete (3%) and 5 partial (14%) responses. In addition, 5 patients experienced stable disease >6 months (14%) while 24 patients had progressive disease (PD, 69%), corresponding to a total DC at 6 months in 11 out of 35 patients (31%). Median progression free survival (PFS) was 2.14 months and median overall survival (OS) was 9 months (1.12-49). Seven of the 11 patients experiencing DC developed early hypertension (<2 months) compared to 3/24 of patients with PD (P = 0.001), and hypertension was associated with PFS (P = 0.005) and OS (P = 0.013). Bevacizumab monotherapy demonstrated promising clinical efficacy in patients with metastatic melanoma with disease control in 31% of the patients. Induced early hypertension was a marker for clinical efficacy of bevacizumab. ClinicalTrials.gov NCT00139360.

    To quantify the relationship between exposure to lacosamide monotherapy and seizure probability, and to simulate the effect of changing the dose regimen. Structural time-to-event models for dropouts (not because of a lack of efficacy) and seizures were developed using data from 883 adult patients newly diagnosed with epilepsy and experiencing focal or generalized tonic-clonic seizures, participating in a trial (SP0993; ClinicalTrials.gov identifier: NCT01243177) comparing the efficacy of lacosamide and carbamazepine controlled-release monotherapy. Lacosamide dropout and seizure models were used for simulating the effect of changing the initial target dose on seizure freedom. Repeated time-to-seizure data were described by a Weibull distribution with parameters estimated separately for the first and subsequent seizures. Daily area under the plasma concentration-time curve was related linearly to the log-hazard. Disease severity, expressed as the number of seizures during the 3 months before the trial (baseline), was a strong predictor of seizure probability: patients with 7-50 seizures at baseline had a 2.6-fold (90% confidence interval 2.01-3.31) higher risk of seizures compared with the reference two to six seizures. Simulations suggested that a 400-mg/day, rather than a 200-mg/day initial target dose for patients with seven or more seizures at baseline could potentially result in an additional 8% of seizure-free patients for 6 months at the last evaluated dose level. Patients receiving lacosamide had a slightly lower dropout risk compared with those receiving carbamazepine. Baseline disease severity was the most important predictor of seizure probability. Simulations suggest that an initial target dose >200 mg/day could potentially benefit patients with greater disease severity.

    Evidence has suggested survival benefits of maintenance for advanced NSCLC patients not progressing after first-line chemotherapy. Additionally, particular first-line targeted therapies have shown survival improvements in selected populations. Optimal first-line and maintenance therapies remain unclear. Here, currently available evidence was synthesized to elucidate optimal first-line and maintenance therapy within patient groups. Literature was searched for randomized trials evaluating first-line and maintenance regimens in advanced NSCLC patients. Bayesian network meta-analysis was performed within molecularly and clinically selected groups. The primary outcome was combined clinically meaningful OS and PFS benefits. A total of 87 records on 56 trials evaluating first-line treatments with maintenance were included. Results showed combined clinically meaningful OS and PFS benefits with particular first-line with maintenance treatments, (1) first-line intercalated chemotherapy+erlotinib, maintenance erlotinib in patients with EGFR mutations, (2) first-line afatinib, maintenance afatinib in patients with EGFR deletion 19, (3) first-line chemotherapy + bevacizumab, maintenance bevacizumab in EGFR wild-type patients, (4) chemotherapy+conatumumab, maintenance conatumumab in patients with squamous histology, (5) chemotherapy+cetuximab, maintenance cetuximab or chemotherapy + necitumumab, maintenance necitumumab in EGFR FISH-positive patients with squamous histology, and (6) first-line chemotherapy+bevacizumab, maintenance bevacizumab or first-line sequential chemotherapy+gefitinib, maintenance gefitinib in patients clinically enriched for EGFR mutations with nonsquamous histology. No treatment showed combined clinically meaningful OS and PFS benefits in patients with EGFR L858R or nonsquamous histology. Particular first-line with maintenance treatments show meaningful OS and PFS benefits in patients selected by EGFR mutation or histology. Further research is needed

    We conducted a prospective, observational study to verify the efficacy, tolerability and impact on quality of life, mood and global neurocognitive performances of oxcarbazepine monotherapy in patients with brain tumor-related epilepsy (BTRE). Patients were followed for 12 months. We recruited 25 patients (11 females 14 males; mean age 49.7) affected with BTRE (17 de novo patients and 7 in monotherapy with other antiepileptics) and introduced oxcarbazepine monotherapy because of uncontrolled seizures and/or side effects. At first visit, patients underwent neurological examination, Qolie 31P V2, EORTC QLQC30, Zung self-depression rating scale (ZSDRS) and adverse events profile. A seizure diary was given to each patient. Follow-up duration was 1-12 months (mean 7.1 months, 5 patients died and 10 dropped out). Totals of 16 patients underwent both chemotherapy and radiotherapy, 4 chemotherapy only, 1 radiotherapy only, and 4 did not undergo any systemic therapy. Mean dosage of oxcarbazepine was 1,230 mg/day (min 600, max 2,100 mg/day). McNemar's test showed a significant difference in seizure freedom rate (P = 0.002) between baseline and final follow-up in the intent-to-treat population. Six patients (24%) had serious side effects and one patient (4%) mild. Logistic regression revealed that, in our study, chemotherapy and radiotherapy did not affect the efficacy of OXC in seizure outcome (P = 0.658). The test evaluation at final follow-up showed a significant improvement in ZSDRS (P = 0.011) and no change over time. Oxcarbazepine seems to be efficacious in controlling seizures and in improving mood in patients with BTRE, but special caution should be taken when it is administered during radiotherapy.

    The extremely weak 2-0 O(14) electric quadrupole transition of N2 has been detected by very high sensitivity Cavity Ring Down spectroscopy near 4518 cm-1. It is the first N2 absorption line in the first overtone band reported so far from laboratory experiments. By combining a feedback narrowed Distributed Feedback laser diode with a passive cell tracking technique, a limit of detection of αmin ∼ 1.2 × 10-11 cm-1 was achieved after one day of spectra averaging. The N2 2-0 O(14) line position and line intensity (about 1.5 × 10-30 cm/molecule) agree with calculated values provided in the HITRAN2012 database.

    IL-2 is a natural, T cell-derived cytokine that stimulates the cytotoxic functions of T and natural killer cells. IL-2 monotherapy has been evaluated in several randomized clinical trials (RCTs) for remission maintenance in patients with acute myeloid leukemia (AML) in first complete remission (CR1), and none demonstrated a significant benefit of IL-2 monotherapy. The objective of this meta-analysis was to reliably determine IL-2 efficacy by combining all available individual patient data (IPD) from 5 RCTs (N = 905) and summary data from a sixth RCT (N = 550). Hazard ratios (HRs) were estimated using Cox regression models stratified by trial, with HR < 1 indicating treatment benefit. Combined IPD showed no benefit of IL-2 over no treatment in terms of leukemia-free survival (HR = 0.97; P = .74) or overall survival (HR = 1.08; P = .39). Analyses including the sixth RCT yielded qualitatively identical results (leukemia-free survival HR = 0.96, P = .52; overall survival HR = 1.06; P = .46). No significant heterogeneity was found between the trials. Prespecified subset analyses showed no interaction between the lack of IL-2 effect and any factor, including age, sex, baseline performance status, karyotype, AML subtype, and time from achievement of CR1 to initiation of maintenance therapy. We conclude that IL-2 alone is not an effective remission maintenance therapy for AML patients in CR1.

    Obeticholic acid (OCA), a potent farnesoid X receptor agonist, was studied as monotherapy in an international, randomized, double-blind, placebo-controlled phase 2 study in patients with primary biliary cholangitis who were then followed for up to 6 years. The goals of the study were to assess the benefit of OCA in the absence of ursodeoxycholic acid, which is relevant for patients who are intolerant of ursodeoxycholic acid and at higher risk of disease progression. Patients were randomized and dosed with placebo (n = 23), OCA 10 mg (n = 20), or OCA 50 mg (n = 16) given as monotherapy once daily for 3 months (1 randomized patient withdrew prior to dosing). The primary endpoint was the percent change in alkaline phosphatase from baseline to the end of the double-blind phase of the study. Secondary and exploratory endpoints included change from baseline to month 3/early termination in markers of cholestasis, hepatocellular injury, and farnesoid X receptor activation. Efficacy and safety continue to be monitored through an ongoing 6-year open-label extension (N = 28). Alkaline phosphatase was reduced in both OCA groups (median% [Q1, Q3], OCA 10 mg -53.9% [-62.5, -29.3], OCA 50 mg -37.2% [-54.8, -24.6]) compared to placebo (-0.8% [-6.4, 8.7]; P < 0.0001) at the end of the study, with similar reductions observed through 6 years of open-label extension treatment. OCA improved many secondary and exploratory endpoints (including γ-glutamyl transpeptidase, alanine aminotransferase, conjugated bilirubin, and immunoglobulin M). Pruritus was the most common adverse event; 15% (OCA 10 mg) and 38% (OCA 50 mg) discontinued due to pruritus. OCA monotherapy significantly improved alkaline phosphatase and other biochemical markers predictive of improved long-term clinical outcomes. Pruritus increased dose-dependently with OCA treatment. Biochemical improvements were observed through 6 years of open-label extension treatment. (Hepatology 2018;67:1890-1902). © 2017 The Authors

    To evaluate the adenosine 2a receptor antagonist preladenant as a nondopaminergic drug for the treatment of Parkinson disease (PD) when given as monotherapy. This was a randomized, 26-week, placebo- and active-controlled, parallel-group, multicenter, double-blind trial conducted in adults diagnosed with PD for <5 years who were not yet receiving l-dopa or dopamine agonists. Patients with a Unified Parkinson's Disease Rating Scale (UPDRS) part 3 (motor function) score ≥10 and Hoehn & Yahr score ≤3 were randomized 1:1:1:1:1 to preladenant 2, 5, or 10 mg twice daily, rasagiline 1 mg (active-control) once daily, or placebo. The primary endpoint was the change from baseline at week 26 in the sum of UPDRS parts 2 (activities of daily living) and 3 scores (UPDRS 2+3 ). The number of patients treated was 1,007. Neither preladenant nor rasagiline was superior to placebo after 26 weeks. The differences vs placebo (95% confidence interval) in UPDRS 2+3 scores (with a negative difference indicating improvement vs placebo) were preladenant 2 mg = 2.60 (0.86, 4.30), preladenant 5 mg = 1.30 (-0.41, 2.94), preladenant 10 mg = 0.40 (-1.29, 2.11), and rasagiline 1 mg = 0.30 (-1.35, 2.03). Post hoc analyses did not identify a single causal factor that could explain the finding of a failed trial. Preladenant was generally well-tolerated with few patients discontinuing due to adverse events (preladenant 7%, rasagiline 3%, placebo 4%). No evidence supporting the efficacy of preladenant as monotherapy was observed in this phase 3 trial. The lack of efficacy of the active control rasagiline makes it difficult to interpret the results. Clinicaltrials.gov: NCT01155479. This study provides Class I evidence that for patients with early PD, preladenant is not effective as monotherapy at the doses studied (2, 5, 10 mg). © 2017 American Academy of Neurology.

    Background Combinations of chemotherapy regimens and monoclonal antibodies have been demonstrated to improve clinical outcomes in patients with metastatic colorectal cancer (mcrc). Although these combination treatment strategies are safe and effective in first-line treatment for mcrc, little is known about their economic consequences and resource allocation implications. In the present study, we evaluated the cost-effectiveness of bevacizumab plus folfiri, cetuximab plus folfiri, and panitumumab plus folfiri for patients with KRAS wild-type mcrc. Methods A Markov model simulated the lifetime patient outcomes and costs of each first-line treatment strategy and subsequent lines of treatment from the perspective of the health care payer in Ontario. The model was parameterized using data from the Ontario Cancer Registry, Ontario health administrative databases, and published randomized control trials. Patient outcomes were measured in quality-adjusted life years (qalys), and costs were measured in monetary terms. Costs and outcomes were both discounted at 5% and expressed in 2012 Canadian dollars. Results For mcrc patients with KRAS wild-type disease, the treatment strategy of bevacizumab plus folfiri was found to dominate the other two first-line treatment strategies. Sensitivity analyses revealed that the incremental cost-effectiveness ratio values were sensitive to the effectiveness of treatment, the costs of bevacizumab and cetuximab, and health utility values. Conclusions Evidence from Ontario showed that bevacizumab plus folfiri is the cost-effective first-line treatment strategy for patients with KRAS wild-type mcrc. The panitumumab plus folfiri and cetuximab plus folfiri options were both dominated, but the cetuximab plus folfiri strategy must be further investigated given that, in the sensitivity analyses, the cost-effectiveness of that strategy was found to be superior to that of bevacizumab plus folfiri under certain ranges of parameter values.

    Abstract The combination of low rather than high dose of dextromethorphan (DXM) with amlodipine (AM) could improve blood pressure (BP) reduction in hypertensive animals. The study aimed to evaluate the feasibility of different doses of DXM combined with standard AM treatment in clinical hypertension. This was a prospective, 14-week, dose-escalation, multicenter study. After 2-week run-in period with AM 5 mg/day, hypertensive patients who got the BP goal of 140/90 mmHg kept receiving AM monotherapy for another 12 weeks. The nonresponders, while kept on AM 5 mg/day, received additional DXM treatment for 3 sequential dose-titrated periods with initially 2.5 mg/day, followed by 7.5 mg/day, and finally 30 mg/day. Each period was for 4 weeks. The patients at BP goal after each treatment period were defined as the responders and kept on the same combination till the end of the study. The responder rate of each treatment period was recorded. The changes of BP and serum antioxidant/endothelial markers between week 14 and week 2 were evaluated. Of the 103 patients initially enrolled, 89 entered the treatment period. In the 78 patients completing the study, 31 (40%) at BP goal after 2-week AM run-in kept on AM monotherapy (DXM0). The addition of 2.5 (DXM2.5) and 7.5 mg/day (DXM7.5) of DXM enabled BP goal achievement in 22 (47%) nonresponders to AM monotherapy including 16 (29%) with DXM2.5 and 6 (18%) with DXM7.5. Only 4 patients (16%) reached BP goal with the combination of DXM 30 mg/day (DXM30). Overall, 73% of the 78 patients reached BP goal at the end of the 14-week study. Mean systolic BP was reduced by 7.9% ± 7.0% with DXM2.5 (P < 0.001) and by 5.4% ± 2.4% with DXM7.5 (P = 0.003) respectively at week 14 from that at week 2, which was unchanged in either DXM0 or DXM30 group. Besides, the effects of combination treatment were particularly significant in the patients with impaired endothelial function suggested by reduced serum NOx level

    Tofacitinib is an oral Janus kinase inhibitor indicated for the treatment of rheumatoid arthritis (RA). Tofacitinib can be administered as a monotherapy or in combination with conventional synthetic disease-modifying antirheumatic drugs (DMARDs). This study describes RA patients' characteristics, treatment patterns, and costs for those initiating tofacitinib treatment as monotherapy or combination therapy, using US claims data from clinical practice. A retrospective cohort analysis of patients aged ≥18 years with RA (International Classification of Diseases, Ninth Revision code 714.xx) and with ≥1 tofacitinib claim in the Truven Marketscan (TM) or the Optum Clinformatics (OC) database. Index was defined as the first tofacitinib fill date (November 2012-June 2014). Patients were continuously enrolled for ≥12 months before and after index. Adherence was assessed using the proportion of days covered (PDC) and medication possession ratio (MPR). Persistence was evaluated using a 1.5× days' supply gap or switch. All-cause and RA-related costs in the 12-month pre- and post-index periods were evaluated. Unadjusted and adjusted analyses were conducted on data on treatment patterns and costs stratified by monotherapy status. A total of 337 (TM) and 118 (OC) tofacitinib patients met the selection criteria; 52.2% (TM) and 50.8% (OC) received monotherapy and 83.7% (TM) and 76.3% (OC) had pre-index biologic DMARD experience. Twelve-month mean PDC values were 0.56 (TM) and 0.53 (OC), and 12-month mean MPR was 0.84 (TM) and 0.80 (OC), with persistence of 140.0 (TM) and 124.6 (OC) days. Between 12-month pre- and post-index periods, mean (SD) 12-month RA-related medical costs decreased by $5784 ($31,832) in TM and $6103 ($25,897) in OC (both, P < 0.05), whereas total costs increased by $3996 ($30,397) in TM (P < 0.05) and $1390 ($26,603) in OC. There were no significant differences in adherence, persistence, or all-cause/RA-related costs between monotherapy and combination

    Evidence related to the effectiveness of combination drug therapy for the treatment of osteoporosis is currently considered insufficient. Therefore, this study was performed to clarify the effects of monotherapy, and combination therapy, with a bisphosphonate (minodronic acid hydrate), a bone resorption inhibitor, and calcitonin (elcatonin), which is effective for the alleviation of pain due to vertebral fractures in osteoporotic patients. Study participants comprised of 51 female subjects with post-menopausal osteoporosis, whose main complaint was acute lower back pain caused by vertebral fractures. Subjects were randomly allocated into three groups and then administered with either intramuscular injections of elcatonin at a dose of 20 units weekly, minodronic acid hydrate at a dose of 1 mg daily, or a combination of these two drugs. As primary endpoints, time-dependent changes in levels of pain were assessed using a visual analog scale from baseline to 6 months of duration. In addition, we examined the effects of monotherapies, and a combination therapy on bone resorption, with changes in bone mineral density at 4 sites and advanced hip assessment parameters from baseline to 6 months. A two-tailed significance level of 5% was used for hypothesis testing. Elcatonin monotherapy showed some alleviation of pain immediately after any vertebral fractures, which was more than in the minodronic acid hydrate monotherapy group. In addition, the minodronic acid hydrate monotherapy group experienced more effective inhibited bone resorption than the elcatonin monotherapy group. In the combination therapy, the efficacy for alleviating pain and inhibiting bone resorption was equivalent to the effect observed in the elcatonin and minodronic acid hydrate monotherapy groups respectively, with further improved values of bone mineral density observed in the femoral neck and lumbar vertebrae, and in parameters of advanced hip assessment compared with both monotherapy groups

    Purpose We aimed to assess the patient-reported outcome (PRO) and efficacy of add-on low-dose antimuscarinic therapy in over-active bladder (OAB) patients with suboptimal response to 4-week treatment with beta 3 agonist monotherapy (mirabegron, 50 mg). Materials and Methods We enrolled OAB patients with 4-week mirabegron (50 mg) treatment if the patients' symptoms improved, but not to a satisfactory extent (patient perception of bladder condition [PPBC] ≥4). Enrolled patients had 8-week low-dose antimuscarinics add-on therapy (propiverine HCl, 10 mg). Patients recorded 3-day voiding diary at screening, enrollment (after 4 weeks of mirabegron monotherapy) and after 8 weeks of add-on therapy. We assessed the change of PRO (PPBC) as a primary end point and the efficacy of add-on therapy (change of frequency, urgency, urinary urgency incontinence [UUI] based on voiding diary) as a secondary end point. Results Thirty patients (mean age, 62.3±12.8 years; mean symptom duration, 16.0±12.3 months) were finally enrolled in the study. The mean PPBC value was 4.3±0.4 after mirabegron monotherapy, and decreased to 3.2±1.0 after 8-week add-on therapy. The mean urinary frequency decreased from 10.1±3.1 to 8.8±3, the mean number of urgency episodes decreased from 3.6±1.6 to 1.8±1.2 and the number of urgency incontinence episodes decreased from 0.7±1.0 to 0.2±0.5 after add-on therapy. No patients had event of acute urinary retention and three patients complained of mild dry mouth after add-on therapy. Conclusions Add-on therapy of low-dose antimuscarinics exhibits good efficacy and safety in patients with suboptimal response after 4-week of mirabegron (50 mg) monotherapy. PMID:28681036

    To evaluate prospectively the changes and possible associations in lipid and thyroid profiles in children treated with oxcarbazepine (OXC) monotherapy. Serum total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglycerides (TGs), lipoprotein (a) [Lp(a)], free thyroxine (FT4), free triiodothyronine (FT3), thyrotropin (TSH) and gamma-glutamyltransferase (GGT) concentrations were measured in 23 children with epilepsy, before and at 8 and 18 months of OXC monotherapy. Total cholesterol was significantly increased at 8 months (P = 0.033), whereas LDL-C was significantly increased at 8 and 18 months (P < 0.001 and P = 0.004, respectively) of treatment. Lp(a) was significantly increased at 8 months (P = 0.042) and borderline significantly increased at 18 months (P = 0.050) of treatment. FT4 was significantly decreased at 8 and 18 months (P < 0.001 and P = 0.002, respectively), and TSH levels were significantly increased at 8 and 18 months (P = 0.002 and P = 0.001, respectively) of OXC monotherapy. GGT levels were significantly increased at 8 and 18 months (P < 0.001) of treatment. There were no significant alterations in HDL-C, TGs and FT3 levels during the study. Significant positive correlations were found between GGT and LDL-C levels at 8 (r = 0.468, P = 0.024) and 18 months (r = 0.498, P = 0.016), and between TSH and TC at 18 months (r = 0.508, P = 0.013) of treatment. OXC monotherapy may cause significant and persistent alterations in lipid and thyroid profiles in children with epilepsy. The increase in LDL-C and TC levels may be associated with liver enzymes induction and thyroid dysfunction. Further long-term prospective studies are required to confirm these findings and to determine their clinical significance. © 2013 The Author(s) European Journal of Neurology © 2013 EFNS.

    To assess the safety profile of lacosamide monotherapy in elderly (≥65 years) subjects with diabetic neuropathic pain (DNP). Of 1,863 DNP subjects in double-blind, randomized, placebo-controlled trials of lacosamide monotherapy (NCT00861445, NCT00235469, NCT00238524, NCT00135109, NCT00350103), 502 were elderly. Safety data from elderly subjects were compared with that of younger subjects (<65 years) within these DNP trials. It should be noted that lacosamide is approved for the treatment of focal (partial-onset) seizures; it is not approved/recommended for the treatment of DNP. Overall, cardiovascular diseases were prevalent in the DNP population, as was the use of cardiac, blood pressure, diabetes, and cholesterol-lowering medications among both young and elderly subjects. The most frequently reported adverse events (AEs) for lacosamide monotherapy (200, 400, and 600 mg/day combined) in elderly versus younger subjects were dizziness (16.2% vs. 13.2%), nausea (10.0% vs. 9.4%), and headache (8.0% vs. 8.7%). Incidences of cardiac disorder AEs were higher in elderly versus younger subjects receiving placebo (6.2% vs. 3.9%), lacosamide 200 (4.8% vs. 3.3%), lacosamide 400 (7.0% vs. 4.1%), and lacosamide 600 mg/day (7.7% vs. 4.0%). Discontinuation rates because of any AE in the elderly versus younger subjects were similar for placebo (8.8% vs. 7.0%) and lacosamide 200 mg/day (9.6% vs. 11.9%) and higher for lacosamide 400 (25.1% vs. 10.8%) and lacosamide 600 mg/day (52.7% vs. 28.3%). Lacosamide monotherapy was well tolerated in elderly subjects with DNP, with an overall AE profile consistent with that reported in epilepsy trials.

    To carry out a cost-minimization analysis including a comparison of the costs arising from first-line treatment by trastuzumab plus docetaxel versus trastuzumab plus paclitaxel in patients with metastatic breast cancer. All consecutive patients with human epidermal growth receptor 2-postive metastatic breast cancer who were treated at Besançon University Hospital and Saint Vincent private hospital between 2001 and 2010 by first-line therapy containing trastuzumab plus taxane were retrospectively studied. Economic analysis took into account costs related to drugs, hospitalization, and healthcare travel. Progression-free survival difference between the two treatments was not significant (p = 0.65). First-line treatment by trastuzumab plus taxane was estimated at approximately €68,000 (p = 0.74). The drug costs represented around 70-75% of the total cost, mainly related to the use of trastuzumab. Our economic analysis shows that although the costs of the two trastuzumab plus taxane regimens are similar, they may contribute to the on-going debate about the availability and use of innovative chemotherapy drugs, in particular in human epidermal growth factor receptor 2-positive metastatic breast cancer with new therapies such as trastuzumab-DM1 and pertuzumab. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Everolimus has been shown to be effective for advanced pancreatic neuroendocrine tumours (pNETs), but its positioning in the therapeutic algorithm for pNETs is matter of debate. With the aim to shed light on this point, we performed an up-to-date critical review taking into account the results of both retrospective and prospective published studies, and the recommendations of international guidelines. In addition, we performed an extensive search on the Clinical Trial Registries databases worldwide, to gather information on the ongoing clinical trials related to this specific topic. We identified eight retrospective published studies, two prospective published studies, and five registered clinical trials. Moreover, we analyzed the content of four widespread international guidelines. Our critical review confirms the lack of high-quality data to recommend everolimus as the first line therapy for pNETs. The ongoing clinical trials reported in this review will hopefully help clinicians, in the near future, to better evaluate the role of everolimus as the first line therapy for pNETs. However, at the moment, there is already enough evidence to recommend everolimus as the first line therapy for patients with symptomatic malignant unresectable insulin-secreting pNETs, to control the endocrine syndrome regardless of tumour growth.

    Background VEGF driven angiogenesis plays a key role in cancer progression. We determined the clinical efficacy of bevacizumab monotherapy in patients with metastatic melanoma. Methods and Findings Thirty-five patients with metastatic melanoma in progression were enrolled in this phase II, single arm clinical trial. Each patient received bevacizumab monotherapy 10 mg/kg q14 d until intolerable toxicity or disease progression occurred. Clinical efficacy was evaluated as objective response, disease control (DC), and survival. We observed one complete (3%) and 5 partial (14%) responses. In addition, 5 patients experienced stable disease >6 months (14%) while 24 patients had progressive disease (PD, 69%), corresponding to a total DC at 6 months in 11 out of 35 patients (31%). Median progression free survival (PFS) was 2.14 months and median overall survival (OS) was 9 months (1.12–49). Seven of the 11 patients experiencing DC developed early hypertension (<2 months) compared to 3/24 of patients with PD (P = 0.001), and hypertension was associated with PFS (P = 0.005) and OS (P = 0.013). Conclusion Bevacizumab monotherapy demonstrated promising clinical efficacy in patients with metastatic melanoma with disease control in 31% of the patients. Induced early hypertension was a marker for clinical efficacy of bevacizumab. Trial Registration ClinicalTrials.gov NCT00139360. PMID:22719881

    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.

    Dolutegravir (DTG) is an integrase strand-transfer inhibitor (INSTI) used for treatment of HIV-infected individuals. Due to its high genetic barrier to resistance, DTG has been clinically investigated as maintenance monotherapy to maintain viral suppression and to reduce complication and healthcare costs. Our study aims to explain the underlying mechanism related to the emergence of a S230R substitution in patients who experienced virological failure while using DTG monotherapy. We evaluated the effect of S230R substitution in regard to IN enzyme activity, viral infectivity, replicative capacity and susceptibility to different INSTIs by biochemical and cell-based assays. S230R substitution conferred 63% reduction in enzyme efficiency. The S230R virus was 1.29-fold less infectious than wildtype (WT), but could replicate in PM1 cells without significant delay. Resistance levels against DTG, CAB, RAL and EVG in tissue culture were 3.85-, 3.72-, 1.52-, and 1.21-fold, respectively. Our data indicate that the S230R substitution is comparable to the previously reported R263K in some respects. Virological failure under DTG monotherapy can occur through the development of such S230R or R263K mutations without the need for high levels DTG resistance.

    To compare a combination of a dihydropyridine calcium-channel blocker with an angiotensin converting enzyme inhibitor vs. monotherapy with one or the other drug and placebo for their effects on home blood pressure (HBP). After a 2-week placebo wash-out, patients with an elevated office blood pressure (BP) (diastolic 100-109 and systolic <180 mmHg) and HBP (diastolic ≥85 mmHg) were randomized double-blind to a 10-week treatment with placebo, lercanidipine, 10 or 20 mg daily, enalapril, 10 or 20 mg daily, or the four possible combinations. In addition to office BP, HBP was self-measured via a validated semiautomatic device twice in the morning and twice in the evening during the 7 days before randomization and at the end of treatment. Baseline and treatment HBP values were separately averaged for each day, morning, evening or the whole monitoring period, excluding the first day. Day-by-day HBP variability was defined as the SD or the variation coefficient of the daily BP averages. Eight hundred and fifty-four patients with valid HBP recordings at baseline and at the end of treatment were analyzed (intention-to-treat population). From the baseline value (147.0±11.6 mmHg) systolic/diastolic HBP showed a small reduction (average baseline-adjusted change: -1.8/-1.6 mmHg) with placebo, a more marked significant fall with monotherapies (-8.8/-5.9 mmHg, P < 0.001/<0.001 vs. placebo) and even more with combination treatment (11.6/-7.6 mmHg, P < 0.001/ < 0.001 vs. placebo and P < 0.01/ < 0.05 vs. monotherapy). A similar pattern was observed for each of the days of the BP self-monitoring period as well as for either morning or evening values, although the difference between mono and combination treatment appeared to be consistently significant for the morning values only. Day-by-day systolic BP-SD was unaffected by placebo and slightly reduced by drug treatments, with no, however, significant changes in SBP-variation coefficient. Baseline and end of

    The objective of this study was to determine the outcome of using ultrasound-guided local methotrexate injection as the first-line treatment of cesarean scar pregnancy (CSP). A literature review was performed on all eligible reports using this modality as the first-line treatment of CSP. Relevant publications were obtained from the PubMed electronic database from inception to December 2014. Ninety-six cases from 95 women reported in 17 articles were reviewed. The success rate was 73.9% after a single local methotrexate injection. An accumulated success rate of 88.5% could be achieved after additional local or intramuscular methotrexate administration. Eleven cases (11.5%) failed methotrexate treatment and required surgical interventions. Except for women with serum human chorionic gonadotropin levels higher than 100 000 IU/L, ultrasound-guided local methotrexate injection could be considered as a first-line treatment modality for CSP.

    Between 1990 and 1999 a total of 186 patients with staghorn renal stones were treated in our unit. Of them, 76 patients were managed by extra-corporeal shockwave lithotripsy (ESWL) alone using a third generation Siemen's Lithostar Plus lithotriptor. Sixty-one of these patients who completed a follow-up of 41 months formed the subjects of this study. ESWL was done after routine stenting of the affected side in all cases except one. The mean number of ESWL sessions was 5.2, delivering an average 15,940 shocks per patient. The average hospital stay was 21.68 days and the duration of the treatment was 1-41 months (mean 6.75 months). Significant complications occurred in 35 patients (57.4%) eight of whom sustained multiple significant complications. A total of 162 auxiliary procedures were used in conjunction with ESWL and in the management of complications. The stone free rate at three months was 18%, but rose by the end of the treatment period (41 months) to 63.9%. Our study indicates that ESWL monotherapy is associated with high morbidity rates, high rates of unplanned invasive procedures as well as prolonged treatment periods and hospitalization. Thus, ESWL monotherapy is not adequate for the management of staghorn calculi.

    We compared rates of neurocognitive impairment (NCI) among 93 Thai adults failing non-nucleoside reverse transcriptase inhibitor (NNRTI)-based combination antiretroviral therapy (cART) before and after switching to lopinavir/ritonavir monotherapy (mLPV/r) vs. tenofovir/lamivudine/LPV/r (TDF/3TC/LPV/r). Participants completed the Color Trails 1 and 2, Digit Symbol, and Grooved Pegboard at weeks 0, 24, and 48. We calculated z-scores using normative data from 451 healthy HIV-negative Thais. We defined NCI as performance of <-1 SD on ≥2 tests. The Thai depression inventory was used to capture depressive symptoms. Lumbar puncture was optional at week 0 and 48. At baseline, median (IQR) age was 36.9 (32.8-40.5) years, and 46 % had primary school education or lower. The median CD4 count was 196 (107-292) cells/mm(3), and plasma HIV RNA was 4.1 (3.6-4.5) log(10) copies/ml. Almost all (97 %) had circulating recombinant CRF01_AE. At baseline, 20 (47 %) of the mLPV/r vs. 22 (44 %) of TDF/3TC/LPV/r arms met NCI criteria (p = 0.89). The frequency of NCI at week 48 was 30 vs. 32 % (p = 0.85) with 6 vs. 7 % (p = 0.85) developing NCI in the mLPV/r vs. TDF/3TC/LPV/r arms, respectively. Having NCI at baseline and lower education each predicted NCI at week 48. Depression scores at week 48 did not differ between arms (p = 0.47). Cerebrospinal fluid HIV RNA of <50 copies/ml at 48 weeks was observed in five out of seven in mLPV/r vs. three out of four in TDF/3TC/LPV/r arm. The rates of NCI and depression did not differ among cases failing NNRTI-based cART who received mLPV/r compared to LPV/r triple therapy.

    Atypical antipsychotic (AAP) drugs are the preferred choice of treatment for schizophrenia patients. Patients who do not show favorable response to AAP monotherapy are subjected to random prolonged therapeutic treatment with AAP multitherapy, typical antipsychotics or a combination of both. Therefore, prior identification of patients' response to drugs can be an important step in providing efficacious and safe therapeutic treatment. We thus attempted to elucidate a genetic signature which could predict patients' response to AAP monotherapy. Our logistic regression analyses indicated the probability that 76% patients carrying combination of four SNPs will not show favorable response to AAP therapy. The robustness of this prediction model was assessed using repeated 10-fold cross validation method, and the results across n-fold cross-validations (mean accuracy=71.91%; 95%CI=71.47-72.35) suggest high accuracy and reliability of the prediction model. Further validations of these results in large sample sets are likely to establish their clinical applicability. Copyright © 2013 Elsevier Inc. All rights reserved.

    Few data are available regarding the treatment of metastatic colorectal cancer elderly patients with anti-EGFR agents in combination with chemotherapy. FOLFOX plus panitumumab is a standard first-line option for RAS wild-type metastatic colorectal cancer. Slight adjustments in chemo-dosage are commonly applied in clinical practice to elderly patients, but those modified schedules have never been prospectively tested. Clinical definition of elderly (≥70 years old) patients that may deserve a more or less intensive combination therapy is still debated. Several geriatric screening tools have been developed to predict survival and risk of toxicity from treatment. Among those, the G8 screening tool has been tested in cancer patients showing the strongest prognostic value for overall survival, while the CRASH score can stratify patients according to an estimated risk of treatment-related toxicities. The PANDA study is a prospective, open-label, multicenter, randomized phase II trial of first-line therapy with panitumumab in combination with dose-adjusted FOLFOX or with 5-fluorouracil monotherapy, in previously untreated elderly patients (≥70 years) with RAS and BRAF wild-type unresectable metastatic colorectal cancer. RAS and BRAF analyses are centralized. Geriatric assessment by means of G8 and CRASH score is planned at baseline and G8 will be re-evaluated at disease progression. The primary endpoint is duration of progression-free survival in both arms. Secondary endpoints include prospective evaluation of the prognostic role of G8 score and the correlation of CRASH risk categories with toxicity. The PANDA study aims at exploring safety and efficacy of panitumumab in combination with FOLFOX or with 5FU/LV in elderly patients affected by RAS and BRAF wild-type metastatic colorectal cancer, to identify the most promising treatment strategy in this setting. Additionally, this is the first trial in which the prognostic role of the G8 score will be prospectively

    Partial onset seizures are often treated with the standard antiepileptic drug carbamazepine. Oxcarbazepine is a newer antiepileptic drug related to carbamazepine that is claimed to be better tolerated. To compare efficacy and tolerability of carbamazepine and oxcarbazepine monotherapy for partial onset seizures. We searched the Cochrane Epilepsy Group Specialised Register (4 August 2009), the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library issue 3, 2009), MEDLINE (January 1966 to May 2008), reference lists of relevant articles and conference proceedings. We also contacted manufacturers and researchers in the field for published or unpublished data. Blinded and unblinded randomised controlled trials of carbamazepine versus oxcarbazepine monotherapy for partial onset seizures. Both authors independently assessed trial quality, according to the guidelines in the Cochrane Reviewer's Handbook, and extracted information about study population, type of intervention, outcome measures and study design. All analyses in this review are by intention-to-treat. We tested for statistical heterogeneity among the identified studies using the chi-squared test. Three trials (723 participants) were included. Only one trial used adequate outcome measures of efficacy; therefore, the results pertaining to efficacy are based on a single trial, whereas the results pertaining to adverse events are based on all three included trials. There was no overall difference in time to treatment withdrawal between the two drugs (hazard ratio (HR) of oxcarbazepine (OXC) versus carbamazepine (CBZ): 1.04, 95% confidence interval (CI) 0.78 to 1.39). Further analyses showed no significant difference in treatment withdrawal for unacceptable side effects (HR of OXC versus CBZ: 0.85, 95% CI 0.59 to 1.24) and in treatment withdrawal for inadequate seizure control (HR of OXC versus CBZ: 1.33, 95% CI 0.82 to 2.15). Oxcarbazepine and carbamazepine appeared to be similarly effective

    The consensus statements regarding first-line therapies in women with ovarian cancer, reached at the Fifth Ovarian Cancer Consensus Conference held in Tokyo, Japan, in November 2015 are reported. Three topics were reviewed and the following statements are recommended: (i) Surgery: the subgroups that should be considered in first-line ovarian cancer clinical trials should be (a) patients undergoing primary debulking surgery and (b) patients receiving neo-adjuvant chemotherapy. The amount of residual disease following surgery should further stratify patients into those with absent gross residual disease and others. (ii) Control arms for chemotherapy: for advanced stage ovarian cancer the standard is intravenous 3-weekly carboplatin and paclitaxel. Acceptable alternatives, which should be stratified variables in trials when more than one regimen is offered, include weekly paclitaxel plus 3-weekly carboplatin, the addition of bevacizumab to 3-weekly carboplatin and paclitaxel, and intraperitoneal therapy. (iii) Trial Endpoints: overall survival is the preferred primary endpoint for first-line clinical trials with or without a maintenance component. Progression-free survival (PFS) is an alternative primary endpoint, but if PFS is chosen overall survival must be measured as a secondary endpoint and PFS must be supported by additional endpoints, including predefined patient reported outcomes and time to first or second subsequent therapy. For neoadjuvant therapy, additional 'window of opportunity' endpoints should be included. © The Author 2017.

    Purpose: To present, analyze, and discuss results of a nationwide, multicenter, retrospective study on high-dose-rate brachytherapy (HDR-BT) as monotherapy for low-, intermediate-, and high-risk prostate cancer. Methods and Materials: From 1995 through 2013, 524 patients, 73 (14%) with low-risk, 207 (40%) with intermediate-risk, and 244 (47%) with high-risk prostate cancer, were treated with HDR-BT as monotherapy at 5 institutions in Japan. Dose fractionations were 27 Gy/2 fractions for 69 patients (13%), 45.5 Gy/7 fractions for 168 (32%), 49 Gy/7 fractions for 149 (28%), 54 Gy/9 fractions for 130 (25%), and others for 8 (2%). Of these patients, 156 (30%) did not receive androgen deprivationmore » therapy, and 202 patients (39%) did receive androgen deprivation therapy <1 year, 112 (21%) for 1-3 years, and 54 (10%) for >3 years. Median follow-up time was 5.9 years (range, 0.4-18.1 years), with a minimum of 2 years for surviving patients. Results: After 5 years, respective actuarial rates of no biochemical evidence of disease, overall survival, cause-specific survival, and metastasis-free survival for all patients were 92%, 97%, 99%, and 94%. For low/intermediate/high-risk patients, the 5-year no biochemical evidence of disease rates were 95%/94%/89%, the 5-year overall survival rates were 98%/98%/94%, the 5-year cause-specific survival rates were 98%/100%/98%, and the 5-year metastasis-free survival rates were 98%/95%/90%, respectively. The cumulative incidence of late grade 2 to 3 genitourinary toxicity at 5 years was 19%, and that of late grade 3 was 1%. The corresponding incidences of gastrointestinal toxicity were 3% and 0% (0.2%). No grade 4 or 5 of either type of toxicity was detected. Conclusions: The findings of this nationwide, multicenter, retrospective study demonstrate that HDR-BT as monotherapy was safe and effective for all patients with low-, intermediate-, and high-risk prostate cancer.« less

    Bullous lichen planus (BLP) is a rare variant of lichen planus, characterized by the development of vesicular and bullous lesions, of skin, nails, hair and/or mucosa. We present a case of 63-year-old woman with BLP, unresponsive to previous therapies with topical corticosteroids, topical calcipotriol, antihistamines and oral cyclosporine (4 mg/kg/day for 4 months). She was already receiving treatment for arterial hypertension, hyperlipidemia, atrial fibrillation and uncontrolled diabetes mellitus. Acitretin was administered for 5 months with complete remission of BLP lesions and no major side effects. This is probably the first reported case of BLP treated with acitretin monotherapy. In this case acitretin was an efficacious and well-tolerated therapeutic option for BLP.

    To describe fulminant toxoplasma retinochoroiditis induced by corticosteroid monotherapy. Clinical records of nine patients were reviewed. All patients (five female, four male; aged 15-64 years) had been misdiagnosed as unilateral non-infectious uveitis and given systemic and/or local corticosteroid injections elsewhere. Mean disease duration before referral was 105.6 ± 71 (45-240) days. Visual acuity at presentation was <20/200 in six eyes. Average lesion size was 6.6 disc areas in eight eyes and all four quadrants were involved in one. Toxoplasma DNA was detected in eight tested eyes. Mean duration of anti-toxoplasmic therapy was 92.5 ± 37.1 days. Three eyes developed rhegmatogenous retinal detachment. Four patients underwent pars plana vitrectomy. Final visual acuity was <20/200 in five eyes. Iatrogenic immunosuppression due to initial misdiagnosis may lead to an aggressive course and serious complications of ocular toxoplasmosis, a potentially self-limiting infection.

    β-blockers are commonly used for the treatment of acute variceal bleeding in cirrhosis. Renin-angiotensin-aldosterone antagonists (angiotensin I-converting enzyme inhibitors, angiotensin receptor blockers and aldosterone antagonists) are potential therapies for portal hypertension. Several studies have compared the renin-angiotensin-aldosterone system (RAAS) inhibitor and β-blocker combination therapy vs. β-blocker monotherapy, with inconsistent results. The aim of the present study was to assess the efficacy of the RAAS inhibitor and β-blocker combination therapy vs. β-blocker monotherapy for hepatic vein pressure gradient (HVPG) reduction in cirrhosis. Studies were obtained using PubMed, Embase, Medline and Cochrane library databases up to July 2015, and the weighted mean difference (WMD) in HVPG reduction was used as a measure of treatment efficacy. In total, three studies (91 patients) were included. When compared to the β-blocker monotherapy, the RAAS inhibitor and β-blocker combination therapy resulted in a significant HVPG reduction [WMD 1.70; 95% confidence interval (CI): 0.52–2.88]. However, there was no significant difference in the heart rate reduction between the monotherapy and combination therapy groups (WMD −0.11; 95% CI: −3.51–3.29). In addition, no significant difference in the hemodynamic response was observed between the two groups (WMD 1.46; 95% CI: 0.93–2.30). In conclusion, the RAAS inhibitor and β-blocker combination therapy reduces portal hypertension significantly and to a greater extent than β-blocker monotherapy. Both therapies reduced the heart rate to similar levels; however, the RAAS inhibitor and β-blocker combination therapy reduced the mean arterial pressure to a greater extent. Due to the limited number of studies included, the data available do not allow a satisfactory comparison of adverse events. Moreover, further larger-scale trials are required in order to strengthen the results of the present study. PMID

    The reduction in recurrent Clostridium difficile-associated diarrhea (CDAD) with fidaxomicin therapy may reduce hospital readmissions and lead to lower overall CDAD costs. However, studies assessing the cost-effectiveness of fidaxomicin as first-line therapy from the U.S. hospital perspective are lacking. This study evaluated the costs associated with utilizing fidaxomicin or vancomycin as a first-line therapy for CDAD in specific patient populations from a U.S. hospital perspective. A decision-analytic model was developed to estimate total costs (hospitalization and drug costs) associated with using fidaxomicin or vancomycin as first-line therapy for a first episode and up to two recurrences of CDAD in five patient populations: general population, elderly, patients receiving concomitant antibiotics, and patients with renal impairment or cancer. The total cost of CDAD treatment using fidaxomicin first line in the general population was $14,442 per patient versus $14,179 per patient with vancomycin first line. In subgroup analyses, fidaxomicin use resulted in total hospital cost savings of $616 per patient in patients with cancer and $312 in patients with concomitant antibiotic use; vancomycin use was associated with total hospital cost savings of $243 per patient in the elderly and $371 in patients with renal impairment. Fidaxomicin as first-line CDAD therapy is associated with similar total costs as compounded vancomycin oral solution in the general population. In elderly and renally impaired patients, slight increases in hospital cost were observed with fidaxomicin therapy, and in patients with cancer or concomitant antibiotic use, hospital cost savings were observed. © 2017 Pharmacotherapy Publications, Inc.

    There is an urgent need for systemic treatment options for patients with castration-resistant prostate cancer who have progressed after receiving first-line docetaxel chemotherapy. The purpose of this article is to review recent developments in this area. Retreatment with docetaxel has been employed with evidence of activity in selected populations. Mitoxantrone, the previous first-line standard based on its palliative effect, has also been used with clinical responses observed; however, the symptom benefit in this setting has not been established. Several classes of cytotoxic agents have been tested including platinum agents (satraplatin), epothilones (ixabepilone and patupilone) and taxanes (XRP-6258). A number of targeted therapies have also been clinically evaluated including inhibitors of cytoprotective chaperones (OGX-011) and the vascular endothelial growth factor receptor (sorafenib, sunitinib, and cediranib). An area generating great interest has been the development of agents that target the androgen receptor axis more effectively (MDV3100 and abiraterone) with encouraging early phase trial results. There is no accepted standard systemic treatment for patients with castration resistant prostate cancer and progressive disease after docetaxel. Novel agents are in phase II and III clinical testing in this setting.

    An oxidant-antioxidant imbalance is considered to be involved in the pathogenesis of idiopathic pulmonary fibrosis (IPF). Therefore, administration of antioxidants, such as N-acetylcysteine (NAC), may represent a potential treatment option for IPF patients. The aim of this study was to evaluate the effect of inhaled NAC monotherapy on lung function and redox balance in patients with IPF. A retrospective observational study was done, involving 22 patients with untreated early IPF (19 men; mean [±S.D.] age, 71.8 [±6.3]y). At baseline and at 6 and 12 months after initiating inhaled NAC monotherapy, we assessed forced vital capacity (FVC) and measured the levels of total glutathione, oxidized glutathione (GSSG), and the ratio of reduced to oxidized glutathione in whole blood (hereafter referred to as the ratio), and of 8-hydroxy-2'-deoxyguanosine in urine. To evaluate response to treatment, we defined disease progression as a decrease in FVC of ≥5% from baseline and stable disease as a decrease in FVC of <5%, over a period of 6 months. Change in FVC in the stable group at 6 and 12 months were 95±170mL and -70±120mL, while those in the progressive group at 6 and 12 months were -210±80mL, -320±350mL, respectively. The serial mean change in GSSG from baseline decreased as the ratio of reduced to oxidized glutathione increased in patients with stable disease, while it increased as this ratio decreased in patients with progressive disease. Receiver operating characteristic curve analysis revealed that a baseline GSSG level of ≥1.579μM was optimal for identifying treatment responders. Inhaled NAC monotherapy was associated with improved redox imbalance in patients with early IPF. Copyright © 2015 The Japanese Respiratory Society. Published by Elsevier B.V. All rights reserved.

    Rasagiline (N-propargyl-1(R)-aminoindan) mesylate is a potent, selective, and irreversible monoamine oxidase-B inhibitor. This study was designed to evaluate the safety, tolerability, and preliminary efficacy of rasagiline monotherapy in early Parkinson's disease (PD) patients not receiving levodopa. The study was performed as a multicenter, parallel-group, double-blind, randomized, placebo-controlled, 10-week study. Fifty-six PD patients were randomly assigned to rasagiline mesylate 1, 2, or 4 mg once daily, or placebo. A 3-week dose-escalation period was followed by a 7-week maintenance phase. At week 10, the mean (+/-SE) changes from baseline in total Unified Parkinson's Disease Rating Scale (UPDRS) score were -1.8 (+/-1.3), -3.6 (+/-1.7), -3.6 (+/-1.2), and -0.5 (+/-0.8) in the rasagiline 1, 2, and 4 mg/day and placebo groups, respectively. Analysis of responders showed that 28% of patients (12 of 43) receiving rasagiline had an improvement in total UPDRS score of greater than 30%, compared with none of the patients receiving placebo (P < 0.05, Fisher's exact test). The frequency and types of adverse events reported by rasagiline-treated and placebo-treated patients were similar. These results suggest that rasagiline monotherapy is well tolerated and efficacious in early PD. Copyright 2004 Movement Disorder Society

    Dementia constitutes an increasingly prevalent cognitive disorder with serious socioeconomic implications. In the present study, we aimed to evaluate the efficacy of aniracetam, either as monotherapy or combined with cholinesterase inhibitors (ChEIs), in terms of several neuropsychological parameters, in a considerable number of patients with dementia. In our prospective, open-label study, we enrolled a total of 276 patients (mean age 71 ± 8 years, 95 males) with cognitive disorders. Our study population comprised four groups: no treatment group (n = 75), aniracetam monotherapy group (n = 58), ChEIs monotherapy group (n = 68), and group of combined treatment (n = 68). Patients were examined with validated neuropsychological tests at baseline, 3, 6, and 12 months of treatment. In patients treated with aniracetam, all studied parameters were adequately maintained at 6 and 12 months, while emotional state was significantly improved at 3 months. In patients treated with ChEIs, we observed a significant cognitive deterioration at 12 months. The comparison between aniracetam and ChEIs in patients with relatively mild dementia (15 ≤ MMSE ≤ 25) revealed a significantly better cognitive performance with aniracetam at 6 months and improved functionality at 3 months. Comparing aniracetam monotherapy with combined treatment in the same population, aniracetam performed better in the cognitive scale at 6 months, and displayed a notable tendency for enhanced mood at 12 months and improved functionality at 6 months. Our findings indicate that aniracetam (a nootropic compound with glutamatergic activity and neuroprotective potential) is a promising option for patients with cognitive deficit of mild severity. It preserved all neuropsychological parameters for at least 12 months, and seemed to exert a favorable effect on emotional stability of demented patients. © 2011 Blackwell Publishing Ltd.

    The objective of this study was to develop and test a 1st-line nurse manager (FLNM) work instrument to measure categories of work and frequency of activities. First-line nurse managers have been demonstrated to be key contributors in meeting organizational outcomes and patient and nurse satisfaction. Identifying the work of FLNMs is essential to help in the development of prioritization and sequence. The need for an instrument that can measure and categorize the work of FLNMs is indicated. The author-developed instrument was administered as a pilot study to 173 FLNMs in New Jersey. Descriptive statistics were analyzed, and validity and reliability were measured. Content validity was established through 2 focus groups using 10 FLNMs and conducting a survey of 5 chief nursing officers. Reliability was assessed by 13 of 16 FLNM participants using the test/retest method and quantified using percent agreement within a 10-day period. Those items with 70% agreement or more were identified as reliable and retained on the instrument. The content validity of the instrument is strong; further refinement and testing of the tool are indicated to improve the reliability and generalizability across multiple populations of leaders and settings.

    Purpose: To report the clinical outcome of high-dose-rate (HDR) interstitial (IRT) brachytherapy (BRT) as sole treatment (monotherapy) for clinically localized prostate cancer. Methods and Materials: Between January 2002 and December 2009, 718 consecutive patients with clinically localized prostate cancer were treated with transrectal ultrasound (TRUS)-guided HDR monotherapy. Three treatment protocols were applied; 141 patients received 38.0 Gy using one implant in 4 fractions of 9.5 Gy with computed tomography-based treatment planning; 351 patients received 38.0 Gy in 4 fractions of 9.5 Gy, using 2 implants (2 weeks apart) and intraoperative TRUS real-time treatment planning; and 226 patients received 34.5 Gy,more » using 3 single-fraction implants of 11.5 Gy (3 weeks apart) and intraoperative TRUS real-time treatment planning. Biochemical failure was defined according to the Phoenix consensus, and toxicity was evaluated using Common Toxicity Criteria for Adverse Events version 3. Results: The median follow-up time was 52.8 months. The 36-, 60-, and 96-month biochemical control and metastasis-free survival rates for the entire cohort were 97%, 94%, and 90% and 99%, 98%, and 97%, respectively. Toxicity was scored per event, with 5.4% acute grade 3 genitourinary and 0.2% acute grade 3 gastrointestinal toxicity. Late grade 3 genitourinary and gastrointestinal toxicities were 3.5% and 1.6%, respectively. Two patients developed grade 4 incontinence. No other instance of grade 4 or greater acute or late toxicity was reported. Conclusion: Our results confirm IRT-HDR-BRT is safe and effective as monotherapy for clinically localized prostate cancer.« less

    The treatment of vitiligo is still one of the most difficult dermatological challenges, although there are many therapeutic options. Narrow band ultraviolet B (NB-UVB) phototherapy is considered to be a very important modality for generalized vitiligo. The aim of this study was to explore whether a combination of NB-UVB and topical agents would be superior to NB-UVB alone for treating vitiligo. We searched the electronic databases such as PUBMED, EMBASE, Cochrane Library, and Web of Science. The primary outcome was the proportion of ≥50% repigmentation (a clinical significance), and secondary outcome was the proportion of ≥75% repigmentation (an excellent response). Seven randomized controlled trials (RCTs) involving 240 patients (413 lesions) were included in this meta-analysis. The study showed no significant difference between NB-UVB combination therapy (NB-UVB and topical calcineurin inhibitor or vitamin D analogs) and NB-UVB monotherapy in the outcomes of ≥50% repigmentation and ≥75% repigmentation. However, lesions located on the face and neck had better results in ≥50% repigmentation (RR = 1.40, 95% CI 1.08-1.81) and ≥75% repigmentation (RR = 1.88, 95% CI 1.10-3.20) with NB-UVB and topical calcineurin inhibitor combination therapy vs. NB-UVB monotherapy. The meta-analysis suggested that adding neither topical calcineurin inhibitors nor topical vitamin-D3 analogs on NB-UVB can yield significantly superior outcomes than NB-UVB monotherapy for treatment of vitiligo. However, addition of topical calcineurin inhibitors to NB-UVB may increase treatment outcomes in vitiligo affecting face and neck. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    In non-small cell lung cancer (NSCLC), the well-developed epidermal growth factor receptor (EGFR) is an important therapeutic target. EGFR activating gene mutations have been proved strongly predictive of response to EGFR-tyrosine kinase inhibitors (TKI) in NSCLC. However, both in daily clinical practice and clinical trials, patients with unknown EGFR gene status (UN-EGFR-GS) are very common. In this study, we assessed efficacy and tolerability of sequential treatment of first-line pemetrexed followed by icotinib in Chinese advanced lung adenocarcinoma with UN-EGFR-GS. We analyzed 38 patients with advanced lung adenocarcinoma with UN-EGFR-GS treated with first-line pemetrexed-based chemotherapy followed by icotinib as maintenance or second-line therapy. The response rates to pemetrexed and icotinib were 21.1% and 42.1%, respectively. The median overall survival was 27.0 months (95% CI, 19.7-34.2 months). The 12-month overall survival probability was 68.4%. The most common toxicities observed in icotinib phase were rashes, diarrheas, and elevated aminotransferase. Subgroup analysis indicated that the overall survival is correlated with response to icotinib. The sequence of first-line pemetrexed-based chemotherapy followed by icotinib treatment is a promising option for advanced lung adenocarcinoma with UN-EGFR-GS in China.

    Fluoropyrimidine and platinum combination is the standard treatment for advanced or recurrent gastric cancer (AGC). However, fluoropyrimidine monotherapy is commonly used for elderly patients with AGC because of its good tolerability. In this multicenter retrospective study, we collected clinical data of AGC patients aged 70 years or older, treated with S-1 alone or S-1 plus cisplatin (SP) as the first-line treatment between January 2009 and December 2011. Propensity score matched cohorts (PSMC) were used for reducing the confounding effects to compare efficacy and safety between the two treatment groups. Cox regression analysis was performed to clarify the prognostic factors. PSMC (n = 109 in each group) were selected from among 444 eligible patients (S-1 group, 210; SP group, 234); the S-1 group included more patients deemed unfit for intensive chemotherapy than the SP group (e.g., higher age, poorer PS, poor renal function). In the PSMC, patients' characteristics were comparable between groups, except the male ratio (S-1 group, 64.2%; SP group, 77.1%; p = 0.04). No significant differences were observed in either overall survival [hazard ratio (HR) 0.93, p = 0.63] or progression-free survival (HR 1.09, p = 0.61). Severe adverse events (AEs) and hospitalization due to AEs were more frequent in the SP group than in the S-1 group (p < 0.001 each). Our findings do not support the survival benefit of SP over S-1 in elderly patients with AGC. We are now conducting a prospective comparative study to optimize treatment strategy and explore applicability of the geriatric assessment for these patients.

    The efficacy of a levofloxacin-based regimen as the first-line treatment and a clarithromycin-based regimen as the second-line treatment for Helicobacter pylori infection remains unknown. The aim of this study was to assess the eradication rates of these two regimens using different administration sequences. Eligible patients were randomised to receive LAL: levofloxacin (750 mg once a day), amoxicillin (1000 mg twice a day) and lansoprazole (30 mg twice a day) for 7 days, or CAL: clarithromycin (500 mg twice a day), amoxicillin (1000 mg twice a day) and lansoprazole (30 mg twice a day) for 7 days. Patients with positive [(13)C]urea breath test after treatment were retreated with the rescue regimen in a crossover manner for 10 days. When used as first-line treatment (n=432), the eradication rates of LAL (n=217) and CAL (n=215) were 74.2 and 83.7% (p=0.015) in the intent-to-treat (ITT) analysis, and 80.1 and 87.4% (p=0.046) in the per-protocol (PP) analysis, respectively. When used as second-line treatment, the eradication rates of LAL (n=26) and CAL (n=40) were 76.9 and 60% (p=0.154) in the ITT analysis, and 80 and 61.5% (p=0.120) in the PP analysis, respectively. The overall eradication rates of CAL followed by LAL were better than the reverse sequence in both the ITT analysis (93% vs 85.3%, p=0.01) and the PP analysis (97.6% vs 92.5%, p=0.019). The eradication rate was significantly lower in the presence of levofloxacin resistance in the LAL group (50% vs 84.4%, p=0.018) and clarithromycin resistance in the CAL group (44.4% vs 90.7%, p=0.002). CAL achieved a higher eradication rate than LAL as the first-line treatment, but not as the second-line treatment. The strategy of using CAL as the initial treatment and LAL as the rescue regimen achieved higher eradication rates than the reverse sequence.

    In a phase 2 study in patients with metastatic renal cell carcinoma, overall survival was associated with T-cell responses against IMA901, a vaccine consisting of ten tumour-associated peptides. In this phase 3 trial, we aimed to determine the clinical effect of adding IMA901 to sunitinib, the standard first-line treatment in metastatic renal cell carcinoma with postulated favourable immunomodulatory effects. The IMPRINT study is an open-label, randomised, controlled, phase 3 trial done at 124 clinical sites in 11 countries. HLA-A*02-positive patients (aged ≥18 years) with treatment-naive, histologically confirmed metastatic or locally advanced (or both) clear-cell renal cell carcinoma were randomly assigned (3:2) to receive sunitinib plus up to ten intradermal vaccinations of IMA901 (4·13 mg) and granulocyte macrophage colony-stimulating factor (75 μg), with one dose of cyclophosphamide (300 mg/m 2 ) 3 days before the first vaccination, or to receive sunitinib alone. Sunitinib (50 mg) was given orally once daily, with each cycle defined as 4 weeks on treatment followed by 2 weeks off treatment, until progression of disease as determined by the investigator, death, or withdrawal of consent. Block randomisation (block size five) was done centrally using an interactive web response system, stratified by prognostic risk, geographical region, and previous nephrectomy. Patients and investigators were not masked to treatment allocation. The primary endpoint was overall survival from randomisation until death of any cause as determined by the investigator, analysed by intention to treat. This study is registered with ClinicalTrials.gov, number NCT01265901. Between Dec 22, 2010, and Dec 15, 2012, we screened 1171 patients, of whom 339 were randomly assigned to receive sunitinib plus IMA901 (n=204) or sunitinib monotherapy (n=135). Patients had a median follow-up of 33·27 months (IQR 29·92-35·64). Median overall survival did not differ significantly between the

    The optimal choice of first-line chemotherapy for patients with relapse of urothelial carcinoma (UC) after perioperative cisplatin-based chemotherapy (PCBC) is unclear. We investigated the outcomes with cisplatin rechallenge versus a non-cisplatin regimen in patients with recurrent metastatic UC after PCBC in a multicenter retrospective study. Individual patient-level data were collected for patients who had received various first-line chemotherapy regimens for advanced UC after previous PCBC. Cox proportional hazards models were used to investigate the prognostic ability of the type of perioperative and first-line chemotherapy to independently affect overall survival (OS) and progression-free survival (PFS) after accounting for known prognostic factors. Data were available for 145 patients (12 centers). The mean age was 62 years; the Eastern Cooperative Oncology Group (ECOG) performance status (PS) was > 0 for 42.0% of the patients. Of the 145 patients, 63% had received cisplatin-based first-line chemotherapy. The median time from previous chemotherapy (TFPC) was 6.2 months (range, 1-154 months). The median OS was 22 months (95% confidence interval [CI], 18-27 months), and the median PFS was 6 months (95% CI, 5-7 months). A better ECOG PS and a longer TFPC (> 12 months vs. ≤ 12 months; hazard ratio [HR], 0.32; 95% CI, 0.20-0.52; P < .001) was prognostic for OS and PFS. Cisplatin-based chemotherapy was associated with poor OS (HR, 1.86; 95% CI, 1.13-3.06; P = .015), which appeared to be pronounced in those patients with a TFPC of ≤ 12 months. Retreatment with cisplatin in the first-line setting was associated with worse OS (HR, 3.38; P < .001). The results of the present retrospective analysis suggest that for patients who have undergone previous PCBC for UC, rechallenging with cisplatin might confer a poorer OS, especially for those with progression within < 1 year.

    To assess the impact on hospitalization costs of multimodal analgesia (MMA), including intravenous acetaminophen (IV-APAP), versus IV opioid monotherapy for postoperative pain management in patients undergoing orthopedic surgery. Utilizing the Truven Health MarketScan ® Hospital Drug Database (HDD), patients undergoing total knee arthroplasty (TKA), total hip arthroplasty (THA), or surgical repair of hip fracture between 1/1/2011 and 8/31/2014 were separated into postoperative pain management groups: MMA with IV-APAP plus other IV analgesics (IV-APAP group) or an IV opioid monotherapy group. All patients could have received oral analgesics. Baseline characteristics and total hospitalization costs were compared. Additionally, an inverse probability treatment weighting [IPTW] with propensity scores analysis further assessed hospitalization cost differences. The IV-APAP group (n = 33,954) and IV opioid monotherapy group (n = 110,300) differed significantly (P < 0.0001) across baseline characteristics, though the differences may not have been clinically meaningful. Total hospitalization costs (mean ± standard deviation) were significantly lower for the IV-APAP group than the IV opioid monotherapy group (US$12,540 ± $9564 vs. $13,242 ± $35,825; P < 0.0001). Medical costs accounted for $701 of the $702 between-group difference. Pharmacy costs were similar between groups. Results of the IPTW-adjusted analysis further supported the statistically significant cost difference. Patients undergoing orthopedic surgery who received MMA for postoperative pain management, including IV-APAP, had significantly lower total costs than patients who received IV opioid monotherapy. This difference was driven by medical costs; importantly, there was no difference in pharmacy costs. Generalizability of the results may be limited to patients admitted to hospitals similar to those included in HDD. Dosing could not be determined, so it was not possible to quantify utilization

    This article examines the roles of continuous ambulatory peritoneal dialysis (CAPD) versus automated peritoneal dialysis (APD) as first-line renal replacement therapy. To date, no high-quality large-scale randomized controlled studies have compared CAPD with APD as first-line therapy. However, a discussion on this issue is important so that nephrologists can decide and patients can have a choice of modality on which to start dialysis, especially in the context of health care economics. We review the literature and present Hong Kong as the model of a "CAPD first" policy, an appealing, cost-effective approach for any country. An ideal renal replacement therapy should provide optimal survival, lowest possible risk for comorbidity, highest level of quality of life, and equally important, acceptable cost to society. When we consider this subject in the context that all patients should be started on one first-line modality, the data suggest that a "CAPD first" policy has all these advantages, with APD probably having the edge only with regard to patient preference. The present review highlights preservation of residual renal function, removal and balancing of sodium, incidence of peritonitis, peritoneal membrane transport status, patient rehabilitation, and financial issues in demonstrating that a "CAPD first" policy is the model that should be adopted.

    The first detection of a quantum particle on a graph is shown to depend sensitively on the distance ξ between the detector and initial location of the particle, and on the sampling time τ . Here, we use the recently introduced quantum renewal equation to investigate the statistics of first detection on an infinite line, using a tight-binding lattice Hamiltonian with nearest-neighbor hops. Universal features of the first detection probability are uncovered and simple limiting cases are analyzed. These include the large ξ limit, the small τ limit, and the power law decay with the attempt number of the detection probability over which quantum oscillations are superimposed. For large ξ the first detection probability assumes a scaling form and when the sampling time is equal to the inverse of the energy band width nonanalytical behaviors arise, accompanied by a transition in the statistics. The maximum total detection probability is found to occur for τ close to this transition point. When the initial location of the particle is far from the detection node we find that the total detection probability attains a finite value that is distance independent.

    We report the first detections of the [NIl] 122 {\\mu} m line from a high redshift galaxy. The line was strongly (> 6{\\sigma}) detected from SMMJ02399-0136, and HI413+ 117 (the Cloverleaf QSO) using the Redshift(z) and Early Universe Spectrometer (ZEUS) on the CSO. The lines from both sources are quite bright with line-to-FIR continuum luminosity ratios that are approx.7.0x10(exp -4) (Cloverleaf) and 2.1x10(exp -3) (SMMJ02399). With ratios 2-10 times larger than the average value for nearby galaxies, neither source exhibits the line-to-continuum deficits seen in nearby sources. The line strengths also indicate large ionized gas fractions, approx.8 to 17% of the molecular gas mass. The [OIII]/[NII] line ratio is very sensitive to the effective temperature of ionizing stars and the ionization parameter for emission arising in the narrow-line region (NLR) of an AGN. Using our previous detection of the [01II] 88 {\\mu}m line, the [OIII]/ [NIl] line ratio for SMMJ02399-0136 indicates the dominant source of the line emission is either stellar HII regions ionized by 09.5 stars, or the NLR of the AGN with ionization parameter 10g(U) = -3.3 to -4.0. A composite system, where 30 to 50% of the FIR lines arise in the NLR also matches the data. The Cloverleaf is best modeled by a superposition of approx.200 M82like starbursts accounting for all of the FIR emission and 43% of the [NIl] line. The remainder may come from the NLR. This work demonstrates the utility of the [NIl] and [OIII] lines in constraining properties of the ionized medium.

    To investigate the effect of rosuvastatin monotherapy on non-alcoholic steatohepatitis (NASH). At present there is no effective treatment for non-alcoholic fatty liver disease or its advanced form NASH. This prospective study included 20 biopsy proven patients with NASH, metabolic syndrome (MetS) and dyslipidaemia. Biochemical parameters of the blood of the patients and an ultrasonography of the liver were performed at baseline. Then patients received lifestyle advice and were treated for a 12 mo period with rosuvastatin (10 mg/d) monotherapy. Patients were re-evaluated during the study at 3 mo intervals, during which biochemical parameters of the blood were measured including liver enzymes. A repeat biopsy and ultrasonography of the liver were performed at the end of the study in all 20 patients. Changes in liver enzymes, fasting plasma glucose, serum creatinine, serum uric acid (SUA), high sensitivity C reactive protein (hsCRP) and lipid profile were assessed every 3 mo. The primary endpoint was the resolution of NASH and the secondary endpoints were the changes in liver enzyme and lipid values. The repeat liver biopsy and ultrasonography showed complete resolution of NASH in 19 patients, while the 20(th), which had no improvement but no deterioration either, developed arterial hypertension and substantial rise in triglyceride levels during the study, probably due to changes in lifestyle including alcohol abuse. Serum alanine transaminase, aspartate transaminase, and γ-glutamyl transpeptidase were normalised by the 3(rd) treatment month (ANOVA P < 0.001), while alkaline phosphatase activities by the 6(th) treatment month (ANOVA, P = 0.01). Fasting plasma glucose and glycated haemoglobin were significantly reduced (P < 0.001). Lipid values were normalised by the 3(rd) treatment month. No patient had MetS by the 9(th) treatment month. Body mass index and waist circumference remained unchanged during the study. Thus, changes in liver pathology and function should

    The predominance of chloroquine-susceptible falciparum malaria in Malawi more than a decade after chloroquine's withdrawal permits contemplation of re-introducing chloroquine for targeted uses. We aimed to compare the ability of different partner drugs to preserve chloroquine efficacy and prevent the re-emergence of resistance. Children with uncomplicated malaria were enrolled at a government health center in Blantyre, Malawi. Participants were randomized to receive chloroquine alone or combined with artesunate, azithromycin or atovaquone-proguanil for all episodes of uncomplicated malaria for one year. The primary outcome was incidence of clinical malaria. Secondary endpoints included treatment efficacy, and incidence of the chloroquine resistance marker pfcrt T76 and of anemia. Of the 640 children enrolled, 628 were included in the intention-to-treat analysis. Malaria incidence (95% confidence interval) was 0.59 (.46-.74), .61 (.49-.76), .63 (.50-.79) and .68 (.54-.86) episodes/person-year for group randomized to receive chloroquine alone or in combination with artesunate, azithromycin or atovaquone-proguanil respectively and the differences were not statistically significant. Treatment efficacy for first episodes was 100% for chloroquine monotherapy and 97.9% for subsequent episodes of malaria. Similar results were seen in each of the chloroquine combination groups. The incidence of pfcrt T76 in pure form was 0%; mixed infections with both K76 and T76 were found in two out of 911 infections. Young children treated with chloroquine-azithromycin had higher hemoglobin concentrations at the study's end than did those in the chloroquine monotherapy group. Sustained chloroquine efficacy with repeated treatment supports the eventual re-introduction of chloroquine combinations for targeted uses such as intermittent preventive treatment.

    Abstract This study aimed to evaluate the efficacy of escitalopram monotherapy in the treatment of major depressive disorder (MDD) on the basis of pooled data analysis of 4 Chinese clinical trials. A total of 649 outpatients with MDD score of ≥18 at the 17-item Hamilton Depression Rating Scale (HAMD17) were included across 4 eligible studies. Patients were treated with 10 mg/day escitalopram for 2 weeks, and then 20 mg/day escitalopram was administered if the clinical response was poor. The change in total HAMD17 score was significantly greater in moderate MDD group than in other subgroups (P < .001), but the proportion of responders and remission rate in moderate MDD group were markedly lower than in mild MDD group. As compared to patients with concomitant anxiety, anxiety free patients showed significant improvement in total HAMD17 score at days 14 and 28 (P < .05). However, there was no significant difference in the change of total HAMD17 score at day 7 and the end of study. According to clinical global impression (CGI) score, the total response rate (very much improved and much improved) was 86.7%. There were 479 adverse events (AEs), but serious AEs were not observed. A total of 3.39% (22/649) of patients withdrew from these studies due to AEs. The most common (incidence ≥2.0%) AEs were nausea, dry mouth, somnolence, dizziness, fatigue, dyspepsia, liver dysfunction, and loss of appetite. Escitalopram monotherapy is effective and safe in the treatment of MDD in Chinese patients, and therapeutic efficacy is dependent on the severity of MDD. Further study is needed to identify better predictors of therapeutic responses. PMID:28953649

    Chemotherapy is the standard treatment of in advanced lung adenocarcinoma patients without driver mutation. However, few drugs could be selected when diseases progressed after second-line treatment. As a small molecule inhibitor of vascular endothelial growth factor receptor-2 (VEGFR-2), apatinib was suggested mainly using in advanced gastric cancer. In this study, we showed the results of apatinib as second-line to fourth-line treatment in EGFR wild-type advanced lung adenocarcinoma patients. 16 EGFR wild-type advanced lung adenocarcinoma patients were administrated apatinib (250-500 mg/d) orally. 3 patients showed partial response and 8 patients showed stable diseases response to apatinib, with a medium progression-free survival (PFS) of 4.4 month (2-10 months). The objective remission rate (ORR) was 18.75%(3/16). The total disease control rate (DCR) was 68.75% (11/16). The main toxicities were hypertension, hand-foot syndrome, proteinuria and thrombocytopenia which were tolerable and manageable. So, apatinib might be an optional choice for post-first-line treatment of EGFR wild-type advanced lung adenocarcinoma patients.

    To assess the blood pressure-lowering efficacy and tolerability of perindopril/amlodipine fixed-dose combinations in Chinese patients with mild-to-moderate essential hypertension not adequately controlled with monotherapy alone. In 2 separate double-blind studies, patients received a 4-week run-in monotherapy of amlodipine 5 mg or perindopril 4 mg, respectively. Those whose blood pressure was uncontrolled were then randomized to receive the fixed-dose combination of perindopril 5 mg/amlodipine 5 mg (Per/Amlo group) or remain on the monotherapy for 8 weeks. Patients who were uncontrolled at the week 8 (W8) visit were up-titrated for the Per/Amlo combination, or received additional treatment if on monotherapy, for a further 4 weeks. The main efficacy assessment was at 8 weeks. After 8 weeks, systolic blood pressure (SBP; primary criterion) was statistically significantly lower in the Per/Amlo group (vs. Amlo 5 mg, p = 0.0095; vs. Per 4 mg, p < 0.0001). Uncontrolled patients at W8 who received an up-titration of the Per/Amlo combination showed a further SBP reduction. These changes were mirrored by reassuring reductions in diastolic blood pressure. The fixed-dose combinations were well tolerated. Single-pill combinations of perindopril and amlodipine provide hypertensive patients with a convenient and effective method of reducing blood pressure. © 2016 S. Karger AG, Basel.

    Pancreatic cancer is one of the most lethal cancer diseases. For years, gemcitabine has been the standard of care and the only therapeutic option in patients with metastatic pancreatic cancer. Within the last years, new combination therapies have been established for first-line treatment, which significantly improve overall survival in comparison to gemcitabine monotherapy. Furthermore, new second-line therapies have been identified, which significantly improve overall survival. The current manuscript summarizes briefly standard of care first- and second-line chemotherapies and discusses possible treatment sequences. © Georg Thieme Verlag KG Stuttgart · New York.

    Prehospital anaesthesia in the United Kingdom (UK) is provided by Helicopter Emergency Medical Service (HEMS) and British Association for Immediate Care (BASICS), a road-based service. Muscle relaxation in rapid sequence induction (RSI) has been traditionally undertaken with the use of suxamethonium; however, rocuronium at higher doses has comparable intubating conditions with fewer side effects. The aim of this survey was to establish how many prehospital services in the UK are now using rocuronium as first line in RSI. An online survey was constructed identifying choice of first-line muscle relaxant for RSI and emailed to lead clinicians for BASICS and HEMS services across the UK. If rocuronium was used, further questions regarding optimal dose, sugammadex, contraindications, and difference in intubating conditions were asked. A total of 29 full responses (93.5%) were obtained from 31 services contacted. Suxamethonium was used first line by 17 prehospital services (58.6%) and rocuronium by 12 (41.4%). In 11 services (91.7%), a dose of 1 mg/kg of rocuronium was used, and in one service, 1.2 mg/kg (8.3%) was used. No services using rocuronium carried sugammadex. In five services, slower relaxation time was found using rocuronium (41.7%), and in seven services, no difference in intubation conditions were noted (58.3%). Contraindications to rocuronium use included high probability of difficult airway and anaphylaxis. Use of rocuronium as first-line muscle relaxant in prehospital RSI is increasing. Continued auditing of practice will ascertain which services have adopted change and identify if complications of failed intubation increase as a result.

    Sevelamer hydrochloride (SH) and lanthanum carbonate (LC) are calcium-free phosphate binders used for the management of hyperphosphatemia in patients with end-stage renal disease (ESRD). The objective of this analysis was to evaluate the real-world dose-relativity between SH and LC monotherapy in US patients with ESRD. This was a post hoc analysis of a 16-week, real-world study (Vemuri et al. in BMC Nephrol 12:49, 2011) of the efficacy of conversion to LC monotherapy from other phosphate binders. The SH:LC dose-relativity ratio, based on the mean daily dose, was calculated in the subset of patients from the Vemuri study who converted from SH to LC monotherapy and had available SH and LC dose data. A total of 950 patients converted from SH to LC monotherapy and had recorded dose data. The post hoc analysis population comprised 691 patients with available dose data for both SH at baseline and LC at week 16. The mean (SD) serum phosphate level at baseline was 5.91 (1.66) mg/dL. After conversion to LC monotherapy for 16 weeks, the mean (SD) serum phosphate level was 5.93 (1.85) mg/dL. The mean (SD) daily baseline SH dose was 7,703 (3,642) mg and the mean (SD) daily LC dose at week 16 was 2,800 (939) mg (9.6 versus 2.8 tablets, respectively; P < 0.0001), resulting in a SH:LC dose-relativity ratio of 2.8. The median individual patient SH:LC dose-relativity ratio was 2.6 (95% CI 2.6-2.8). Across baseline SH dose subgroups (2,400-4,800, >4,800-7,200, >7,200-9,600, and >9,600 mg/day), the mean daily SH dose was 4,051, 7,047, 9,253, and 13,150 mg, respectively. In comparison, the mean daily LC dose was 2,445-3,156 mg. Thus, patients requiring baseline SH doses >7,200 mg/day (41% of the analysis population) had higher SH:LC dose-relativity ratios of 3.1-4.2 (median individual patient ratios 3.1-4.0). In this post hoc analysis of real-world dose-relativity, the overall SH:LC dose-relativity ratio was 2.8 (median individual patient ratio 2.6 (95% CI 2.6-2.8). These findings are

    Dilated cardiomyopathy (DCM) is a common cause of morbidity and mortality in the Irish Wolfhound (IW). However, the benefit of medical treatment in IW dogs with preclinical DCM, atrial fibrillation (AF), or both has not been demonstrated. Compare the time to develop congestive heart failure (CHF) or sudden death in IW dogs with preclinical DCM, AF, or both receiving monotherapy with pimobendan, methyldigoxin, or benazepril hydrochloride. Seventy-five client-owned IW dogs. Irish Wolfhound dogs were prospectively randomized to receive pimobendan (Vetmedin®), benazepril HCl (Fortekor®), or methyldigoxin (Lanitop®) monotherapy in a 1:1:1 ratio in a blinded clinical trial. The prospectively defined composite primary endpoint was onset of CHF or sudden death. To assure stringent evaluation of treatment effect, data from dogs complying with the study protocol were analyzed. Sixty-six IW fulfilling the study protocol included 39 males, 27 females; median (interquartile range) age, 4.0 years (3.0-5.0 years) and weight, 70.0 kg (63.0-75.0 kg). Primary endpoint was reached in 5 of 23 (21.7%) IW receiving pimobendan, 11 of 22 (50.0%) receiving benazepril HCl, and 9 of 21 (42.9%) receiving methyldigoxin. Median time to primary endpoint was significantly longer for pimobendan (1,991 days; 65.4 months) compared to methyldigoxin (1,263 days; 41.5 months; P = .031) or benazepril HCl-(997 days; 32.8 months; P = .008) treated dogs. In IW dogs with preclinical DCM, AF or both, pimobendan monotherapy significantly prolonged time to onset of CHF or sudden death than did monotherapy with benazepril HCl or methyldigoxin.

    Eslicarbazepine acetate (ESL, Aptiom®) is a once-daily (QD) anticonvulsant, approved as adjunctive treatment of partial-onset seizures (POS). It is extensively converted after oral administration to eslicarbazepine, and is believed to exert its effect through inhibition of voltage-gated sodium channels. The possible role of ESL as monotherapy to treat POS has not yet been established. This study was an 18-week, multicenter, randomized double-blind trial of gradual conversion to ESL monotherapy in adults with POS not well controlled by 1-2 antiepileptic drugs (AEDs), using historical data as the control. The study comprised an 8-week baseline period, a 2-week titration period, a 6-week AED conversion period, a 10-week monotherapy period, and either a 1-week taper period or optional entry to an open-label extension study. The primary endpoint compared the Kaplan-Meier (KM)-estimated 112-day exit rate with a threshold value calculated from the historical controls. There were 172 randomized patients; 154 (90%) entered the AED conversion period and 121 (70%) completed the study. The KM-estimated exit rates [confidence interval (CI)] were 15.6% [8.1-28.7%] for ESL 1200 mg, and 12.8% [7.5-21.5%] for ESL 1600 mg. The upper limits of the 95% CI KM-estimates were below the pre-specified threshold for historical control of 65.3%, indicating that ESL was efficacious in reducing seizure-related exits, compared with historical control. During the 18-week double-blind treatment period, median reductions in standardized seizure frequency occurred with ESL 1200 mg (36.1%) and ESL 1600 mg (47.5%). The responder rates (a 50% or greater reduction in seizure frequency from baseline) during the 18-week double-blind period and the monotherapy period, respectively, were 35.2% and 38.9% for ESL 1200 mg, and 46.0% and 46.0% for ESL 1600 mg. The overall adverse event profile was consistent with the known safety profile of ESL. These findings indicate that ESL monotherapy (1200 and

    Summary Background Standard-of-care antiretroviral therapy (ART) uses a combination of drugs deemed essential to minimise treatment failure and drug resistance. Protease inhibitors are potent, with a high genetic barrier to resistance, and have potential use as monotherapy after viral load suppression is achieved with combination treatment. We aimed to assess clinical risks and benefits of protease inhibitor monotherapy in long-term clinical use: in particular, the effect on drug resistance and future treatment options. Methods In this pragmatic, parallel-group, randomised, controlled, open-label, non-inferiority trial, we enrolled adults (≥18 years of age) positive for HIV attending 43 public sector treatment centres in the UK who had suppressed viral load (<50 copies per mL) for at least 24 weeks on combination ART with no change in the previous 12 weeks and a CD4 count of more than 100 cells per μL. Participants were randomly allocated (1:1) to maintain ongoing triple therapy (OT) or to switch to a strategy of physician-selected ritonavir-boosted protease inhibitor monotherapy (PI-mono); we recommended ritonavir (100 mg)-boosted darunavir (800 mg) once daily or ritonavir (100 mg)-boosted lopinavir (400 mg) twice daily, with prompt return to combination treatment if viral load rebounded. All treatments were oral. Randomisation was with permuted blocks of varying size and stratified by centre and baseline ART; we used a computer-generated, sequentially numbered randomisation list. The primary outcome was loss of future drug options, defined as new intermediate-level or high-level resistance to one or more drugs to which the patient's virus was deemed sensitive at trial entry (assessed at 3 years; non-inferiority margin of 10%). We estimated probability of rebound and resistance with Kaplan-Meier analysis. Analyses were by intention to treat.

    Eslicarbazepine acetate (ESL, Aptiom™) is a once-daily anticonvulsant, approved as adjunctive treatment of partial-onset seizures (POS). Historical-controlled trials investigating the use of ESL as monotherapy have demonstrated a favorable efficacy and tolerability profile in patients with POS. This prospective, non-interventional study recruited POS patients in 17 hospitals in Spain. After a 3-month baseline period, ESL therapy was initiated as 400mg QD and up-titrated to an optimal maintenance dose based on clinical response and tolerance. The incidence of seizures was assessed via seizure calendars and the nature and severity of adverse events (AEs) were also recorded. A total of 117 patients (aged 9-87years) enrolled in the study and were treated with ESL at either 400mg/day (3.4% patients), 800mg/day (61% patients), 1200mg/day (27.1% patients) or 1600mg/day (8.5% patients). At 3months, 82.0% (n=72) of patients achieved a ≥50% reduction in seizure frequency, compared to 79.7% (n=67) of patients at 6months and 83.0% (n=49) at 12months. Patients who suffered secondary generalized tonic-clonic (SGTC) seizures had seizure-free rates of 71% (n=27), 69.6% (n=29), and 72.7% (n=16) at 3, 6, and 12months, respectively. Overall, 18 patients (15.3%) reported AEs of instability and dizziness (n=9), somnolence (n=3), mild hyponatremia (n=3), headache (n=1), hypertriglyceridemia (n=1), and allergic reaction (n=1), which caused ESL discontinuation of ESL treatment. ESL is effective and well tolerated as monotherapy for patients with POS, which supports previous findings. Early use is supported by its frequent use as monotherapy in this study and lack of severe side effects. Copyright © 2017 Elsevier Inc. All rights reserved.

    Gamma-ray lines are produced in nature by a variety of different physical processes. They can be valuable astrophysical diagnostics providing information the may be unobtainable by other means. We have carried out an extensive search for gamma-ray lines in the first year of public data from the Spectrometer (SPI) on the INTEGRAL mission. INTEGRAL has spent a large fraction of its observing time in the Galactic Plane with particular concentration in the Galactic Center (GC) region (approximately 3 Msec in the first year). Hence the most sensitive search regions are in the Galactic Plane and Center. The phase space of the search spans the energy range 20-8000 keV, and line widths from 0-1000 keV (FWHM) and includes both diffuse and point-like emission. We have searched for variable emission on time scales down to approximately 1000 sec. Diffuse emission has been searched for on a range of different spatial scales from approximately 20 degrees (the approximate field-of-view of the spectrometer) up to the entire Galactic Plane. Our search procedures were verified by the recovery of the known gamma-ray lines at 511 keV and 1809 keV at the appropriate intensities and significances. We find no evidence for any previously unknown gamma-ray lines. The upper limits range from a few x10(exp -5) per square centimeter per second to a few x10(exp -3) per square centimeter per second depending on line width, energy and exposure. Comparison is made between our results and various prior predictions of astrophysical lines

    Background This is an update of a Cochrane review that was first published in Issue 1, 2009. Gestational trophoblastic neoplasia (GTN) is a rare but curable disease arising in the fetal chorion during pregnancy. Most women with low-risk GTN will be cured by evacuation of the uterus with or without single-agent chemotherapy. However, chemotherapy regimens vary between treatment centres worldwide and the comparable benefits and risks of these different regimens are unclear. Objectives To determine the efficacy and safety of first-line chemotherapy in the treatment of low-risk GTN. Search methods In September 2008, we electronically searched the Cochrane Gynaecological Cancer Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL Issue 3, 2008), MEDLINE and EMBASE. In addition, we searched online trial registers, conference proceedings and reference lists of identified studies. We re-ran these searches in February 2012 for this updated review. Selection criteria For the original review, we included randomised controlled trials (RCTs), quasi-RCTs and non-RCTs that compared first-line chemotherapy for the treatment of low-risk GTN. For this updated version of the review, we included only RCTs. Data collection and analysis Two review authors independently assessed studies for inclusion and extracted data to a pre-designed data extraction form. Meta-analysis was performed by pooling the risk ratio (RR) of individual trials. Main results We included five moderate to high quality RCTs (517 women) in the updated review. These studies all compared methotrexate with dactinomycin. Three studies compared weekly intramuscular (IM) methotrexate with bi-weekly pulsed intravenous (IV) dactinomycin (393 women), one study compared five-day IM methotrexate with bi-weekly pulsed IV dactinomycin (75 women) and one study compared eight-day IM methotrexate-folinic acid (MTX-FA) with five-day IV dactinomycin (49 women). Overall, dactinomycin was associated

    The aim of this meta-analysis was to evaluate efficacy and safety of first-line chemotherapy with or without a monoclonal antibody in elderly patients (≥ 70 years) with metastatic colorectal cancer (mCRC), since they are frequently underrepresented in clinical trials. Individual data from 10 studies were included. From a total of 3271 patients, 604 patients (18%) were ≥ 70 years (median 73 years, range 70-88). Of these, 335 patients were treated with a bevacizumab-based first-line regimen and 265 were treated with chemotherapy only. The median PFS was 8.2 vs. 6.5 months and the median OS was 16.7 vs. 13.0 months in patients treated with and without bevacizumab, respectively. The safety profile of bevacizumab in combination with first-line chemotherapy did not differ from published clinical trials. PubMed and Cochrane Library searches were performed on 29 April 2013 and studies published to this date were included. Authors were contacted to request progression-free survival (PFS), overall survival (OS) data, patient data on treatment regimens, age, sex and potential signs of toxicity in patients ≥ 70 years of age. This meta-analysis suggests that the addition of bevacizumab to standard first-line chemotherapy improves clinical outcome in elderly patients with mCRC and is well tolerated.

    We report the first detections of the [N II] 122 micron line from a high-redshift galaxy. The line was strongly (>6(sigma)) detected from SMMJ02399-0136, and H1413 + 117 (the Cloverleaf QSO) using the Redshift (zeta) and Early Universe Spectrometer on the Caltech Submillimeter Observatory. The lines from both sources are quite bright with line to far-infrared (FIR) continuum luminosity ratios that are approx.7.0 x 10(exp -4) (Cloverleaf) and 2.1 x 10(exo -3) (SMMJ02399). With ratios 2-10 times larger than the average value for nearby galaxies, neither source exhibits the line to continuum deficits seen in nearby sources. The line strengths also indicate large ionized gas fractions, approx.8%-17% of the molecUlar gas mass. The [O III]/[N II] line ratio is very sensitive to the effective temperature of ionizing stars and the ionization parameter for emission arising in the narrow-line region (NLR) of an active galactic nucleus (AGN). Using Our previous detection of the [O III] 88 micron line, the [O III]/[N II]line ratio for SMMJ02399-0136 indicates that the dominant source of the line emission is either stellar H II regions ionized by O9.5 stars, or the NLR of the AGN with ionization parameter log(U) = -3.3 to -4.0. A composite system, where 30%-50% of the FIR lines arise in the NLR also matches the data. The Cloverleaf is best modeled by a superposition of approx.200 M82-like starbursts accounting for all of the FIR emission and 43% of the [N II]line. The remainder may come from the NLR. This war!< demonstrates the utility of the [N II] and [O III] lines in constraining properties of the ionized medium.

    Epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) is effective as first-line chemotherapy for patients with advanced non-small-cell lung cancer (NSCLC) harboring sensitive EGFR mutations. However, whether the efficacy of second-line cytotoxic drug chemotherapy after first-line EGFR-TKI treatment is similar to that of first-line cytotoxic drug chemotherapy in elderly patients aged ≥ 75 years harboring sensitive EGFR mutations is unclear. Therefore, we aimed to investigate the efficacy and safety of cytotoxic drug chemotherapy after first-line EGFR-TKI treatment in elderly patients with NSCLC harboring sensitive EGFR mutations. We retrospectively evaluated the clinical effects and safety profiles of second-line cytotoxic drug chemotherapy after first-line EGFR-TKI treatment in elderly patients with NSCLC harboring sensitive EGFR mutations (exon 19 deletion/exon 21 L858R mutation). Between April 2008 and December 2015, 78 elderly patients with advanced NSCLC harboring sensitive EGFR mutations received first-line EGFR-TKI at four Japanese institutions. Baseline characteristics, regimens, responses to first- and second-line treatments, whether or not patients received subsequent treatment, and if not, the reasons for non-administration were recorded. Overall, 20 patients with a median age of 79.5 years (range 75-85 years) were included in our analysis. The overall response, disease control, median progression-free survival, and overall survival rates were 15.0, 60.0%, 2.4, and 13.2 months, respectively. Common adverse events included leukopenia, neutropenia, anemia, thrombocytopenia, malaise, and anorexia. Major grade 3 or 4 toxicities included leukopenia (25.0%) and neutropenia (45.0%). No treatment-related deaths were noted. Second-line cytotoxic drug chemotherapy after first-line EGFR-TKI treatment among elderly patients with NSCLC harboring sensitive EGFR mutations was effective and safe and showed equivalent outcomes to first-line

    No evidence can be found in the medical literature about the efficacy of alternating acetaminophen and ibuprofen treatment in children with refractory fever. Our objective was to assess the effect of alternating acetaminophen and ibuprofen therapy on distress and refractory fever compared with acetaminophen or ibuprofen as monotherapy in febrile children. A total of 474 febrile children with axillary temperature ≥38.5 °C and fever history ≤3 days in a tertiary hospital were randomly assigned to receive either (1) alternating acetaminophen and ibuprofen (acetaminophen 10 mg/kg per dose with shortest interval of 4 h and ibuprofen 10 mg/kg per dose with shortest interval of 6 h and the shortest interval between acetaminophen and ibuprofen ≥2 h; n = 158), (2) acetaminophen monotherapy (10 mg/kg per dose with shortest interval of 4 h; n = 158), or (3) ibuprofen monotherapy (10 mg/kg per dose with shortest interval of 6 h; n = 158). The mean Non-Communicating Children's Pain Checklist (NCCPC) score was measured every 4 h, and axillary temperatures were measured every 2 h. In total, 471 children were included in an intention-to-treat analysis. No significant clinical or statistical difference was found in mean NCCPC score or temperature during the 24-h treatment period in all febrile children across the three groups. Although the proportion of children with refractory fever for 4 h and 6 h was significantly lower in the alternating group than in the monotherapy groups (4 h: 11.54% vs. 26.58% vs. 21.66%, respectively [p = 0.003]; 6 h: 3.85% vs. 10.13% vs. 17.83%, respectively [p < 0.001]), the mean NCCPC score of children with refractory fever for 4 or 6 h was not lower than those in either of the monotherapy groups. The number of patients who developed persistent high body temperature was consistent across all study groups. Alternating acetaminophen and ibuprofen can reduce the proportion of children with refractory fever, but if one cycle

    Colorectal cancer is one of the most common malignancies in the United States, with a large proportion of patients presenting with metastatic disease or developing a recurrence. Systemic chemotherapy is the mainstay of therapy in this setting. There is a clear benefit in the addition of bevacizumab or cetuximab (for rat sarcoma [RAS] wild type tumors) to oxaliplatin- and irinotecan-based regimens which can be considered for first-line therapy. However, many significant questions remain as to which agent reflects best practice. Our review aimed to elucidate the benefit of adding bevacizumab and cetuximab to initial therapy for metastatic colorectal cancer based on primary tumor location and a variety of other disease- and patient-related factors, addressing the paucity of evidence that currently exists in this area and contributing to current literature and clinical practices. The primary endpoints of the study were first Progression-Free Survival (PFS) and Overall Survival (OS). Secondary endpoints included best response to first- and second-line therapies, Treatment- Related Adverse Events (TRAEs), second PFS, cost of therapy, and an assessment of other patient- and disease-related factors affecting PFS and OS. While there were trends towards improved OS in patients with left-sided primary tumors (n=57) compared to those with right-sided disease (n=23), there were no significant differences between the two groups in either primary endpoint. While no differences were found for patients with left- or right- sided tumors stratified by add-on agent, these analyses were limited by the small number of patients receiving cetuximab with first-line therapy (n=4). However, the bevacizumab cohort (n=76) was sizable enough to provide ample data and produce clinically relevant results. Add-on therapy with bevacizumab in our study achieved impressive survival outcomes in both left-sided (median first PFS = 13 months, 95% CI 11-15 months; median OS = 37 months, 95% CI 21

    Background In the Asia-Pacific region many countries have adopted the WHO’s public health approach to HIV care and treatment. We performed exploratory analyses of the factors associated with first major modification to first-line combination antiretroviral therapy (ART) in resource-rich and resource-limited countries in the region. Methods We selected treatment naive HIV-positive adults from the Australian HIV Observational Database (AHOD) and the TREAT Asia HIV Observational Database (TAHOD). We dichotomised each country’s per capita income into high/upper-middle (T-H) and lower-middle/low (T-L). Survival methods stratified by income were used to explore time to first major modification of first-line ART and associated factors. We defined a treatment modification as either initiation of a new class of antiretroviral (ARV) or a substitution of two or more ARV agents from within the same ARV class. Results A total of 4250 patients had 961 major modifications to first-line ART in the first five years of therapy. The cumulative incidence (95% CI) of treatment modification was 0.48 (0.44–0.52), 0.33 (0.30–0.36) and 0.21 (0.18–0.23) for AHOD, T-H and T-L respectively. We found no strong associations between typical patient characteristic factors and rates of treatment modification. In AHOD, relative to sites that monitor twice-yearly (both CD4 and HIV RNA-VL), quarterly monitoring corresponded with a doubling of the rate of treatment modifications. In T-H, relative to sites that monitor once-yearly (both CD4 and HIV RNA-VL), monitoring twice-yearly corresponded to a 1.8 factor increase in treatment modifications. In T-L, no sites on average monitored both CD4 & HIV RNA-VL concurrently once-yearly. We found no differences in rates of modifications for once- or twice-yearly CD4 count monitoring. Conclusions Low-income countries tended to have lower rates of major modifications made to first-line ART compared to higher-income countries. In higher-income countries

    To assess the efficacy and safety of eslicarbazepine acetate (ESL) as monotherapy in North American patients with partial-onset seizures (POS). This multicenter, randomized, double-blind "withdrawal to monotherapy" study used historical control data as the comparator. Adults with POS medically uncontrolled by one to two antiepileptic drugs gradually converted to ESL monotherapy. Following an 8-week baseline period, patients were randomized 2:1 to receive ESL 1,600 mg (n = 128) or 1,200 mg QD (n = 65) for 18 weeks. The primary end point was the proportion of patients meeting predefined exit criteria (signifying worsening seizure control). Treatment was considered effective if the 95% upper confidence limit (UCL) for the Kaplan-Meier estimated exit rate was lower than the exit rate threshold calculated from the historical control (65.3%). Kaplan-Meier estimated exit rates were: ESL 1,600 mg, 28.7% (95% CI 21.2-38.1%) and 1,200 mg, 44.4% (32.5-58.3%). The difference between doses was not significant (p = 0.07). For both doses, the 95% UCLs for the exit rate were ˂ 65.3%; ESL monotherapy was considered superior to the historical control. There was no statistically significant increase in the risk of study exit related to carbamazepine use. Nine (7.6%) and five patients (8.3%) remained seizure-free during the 10-week monotherapy period, while taking ESL 1,600 and 1,200 mg, respectively. The reductions in median standardized seizure frequency (seizures per 28 days) between baseline and the 18-week treatment period were: ESL 1,600 mg, 42% and 1,200 mg, 31%. Treatment-emergent adverse events (TEAEs) occurring in ≥ 10% of patients were dizziness, headache, fatigue, somnolence, nausea, and nasopharyngitis. The TEAE most frequently leading to discontinuation was hyponatremia (2.1%). ESL was efficacious and well tolerated as monotherapy in North American patients, and led to a reduction in seizure frequency. Exit rates for ESL 1,600 and 1,200 mg QD were superior to the

    Background The predominance of chloroquine-susceptible falciparum malaria in Malawi more than a decade after chloroquine's withdrawal permits contemplation of re-introducing chloroquine for targeted uses. We aimed to compare the ability of different partner drugs to preserve chloroquine efficacy and prevent the re-emergence of resistance. Methodology/Principal Findings Children with uncomplicated malaria were enrolled at a government health center in Blantyre, Malawi. Participants were randomized to receive chloroquine alone or combined with artesunate, azithromycin or atovaquone-proguanil for all episodes of uncomplicated malaria for one year. The primary outcome was incidence of clinical malaria. Secondary endpoints included treatment efficacy, and incidence of the chloroquine resistance marker pfcrt T76 and of anemia. Of the 640 children enrolled, 628 were included in the intention-to-treat analysis. Malaria incidence (95% confidence interval) was 0.59 (.46–.74), .61 (.49–.76), .63 (.50–.79) and .68 (.54–.86) episodes/person-year for group randomized to receive chloroquine alone or in combination with artesunate, azithromycin or atovaquone-proguanil respectively and the differences were not statistically significant. Treatment efficacy for first episodes was 100% for chloroquine monotherapy and 97.9% for subsequent episodes of malaria. Similar results were seen in each of the chloroquine combination groups. The incidence of pfcrt T76 in pure form was 0%; mixed infections with both K76 and T76 were found in two out of 911 infections. Young children treated with chloroquine-azithromycin had higher hemoglobin concentrations at the study's end than did those in the chloroquine monotherapy group. Conclusion/Significance Sustained chloroquine efficacy with repeated treatment supports the eventual re-introduction of chloroquine combinations for targeted uses such as intermittent preventive treatment.

    To analyse the learning curve for the management of tyrosine kinase inhibitors as the first line of treatment for patients with metastatic renal cancer. We evaluated 32 consecutive patients treated in our department for metastatic renal cancer with tyrosine kinase inhibitors (pazopanib or sunitinib) as first-line treatment between September 2012 and November 2015. We retrospectively analysed this sample. We measured the time to the withdrawal of the first-line treatment, the time to progression and overall survival using Kaplan-Meier curves. The learning curve was analysed with the cumulative sum (CUSUM) methodology. In our series, the median time to the withdrawal of the first-line treatment was 11 months (95% CI 4.9-17.1). The mean time to progression was 30.4 months (95% CI 22.7-38.1), and the mean overall survival was 34.9 months (95% CI 27.8-42). By applying the CUSUM methodology, we obtained a graph for the CUSUM value of the time to withdrawal of the first-line treatment (CUSUM TW), observing 3 well-differentiated phases: phase 1 or initial learning phase (1-15), phase 2 (16-26) in which the management of the drug progressively improved and phase 3 (27-32) of maximum experience or mastery of the management of these drugs. The number of treated patients needed to achieve the proper management of these patients was estimated at 15. Despite the limitations of the sample size and follow-up time, we estimated (in 15 patients) the number needed to reach the necessary experience in the management of these patients with tyrosine kinase inhibitors. We observed no relationship between the time to the withdrawal of the first-line treatment for any cause and progression. Copyright © 2018 AEU. Publicado por Elsevier España, S.L.U.

    The aim of this study was to compare the efficacy and safety of golimumab (GLM) 50 mg + methotrexate (MTX) combination therapy and GLM 100 mg monotherapy in patients with rheumatoid arthritis (RA). The subjects were 115 RA patients (92 females and 23 males; median (range) age, 64 (17-87) years; median (range) disease duration, 8 (0.6-48) years) started on GLM. Eighty-three patients received GLM 50 mg/4 weeks + MTX (C group; median (range) MTX dosage 8 (2-16) mg/week), and 32 patients received GLM 100 mg/4 weeks (M group). Serum C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), matrix metalloproteinase-3, disease activity score (DAS) 28-ESR, DAS28-CRP, simplified disease activity index, and clinical disease activity index were evaluated 4, 12, and 24 weeks after starting GLM. There were no significant differences in disease activity, adverse events, and drug continuation rates at 24 weeks between the groups. The DAS28-ESR remission rate was 34% in the C group and 26% in the M group. GLM 100 mg monotherapy improved disease activity as well as GLM 50 mg + MTX combination therapy. GLM 100 mg monotherapy appears to have a sufficient therapeutic effect in RA patients who cannot take MTX.

    Vadastuximab talirine (SGN-CD33A, 33A) is an antibody-drug conjugate consisting of pyrrolobenzodiazepine dimers linked to a monoclonal antibody targeting CD33, which is expressed in the majority of acute myeloid leukemia (AML) patients. This phase 1 study evaluated the safety, pharmacokinetics, and preliminary activity of vadastuximab talirine and determined the recommended monotherapy dose in patients with relapsed or refractory AML. Additional expansion cohorts tested vadastuximab talirine in specific subpopulations of relapsed AML, and in a cohort of older, treatment-naive patients. Patients received vadastuximab talirine IV on day 1 (5-60 µg/kg) or on days 1 and 4 (20 µg/kg) of 21-day cycles. A total of 131 patients (median age, 73 years [range, 26-89 years]) had intermediate I-II (48%) or adverse (34%) risk by European LeukemiaNet classification; 50% of patients had underlying myelodysplasia. Two dose-limiting toxicities (grade 2 pulmonary embolism and grade 4 hypocellular marrow) occurred during dose finding. Most adverse events (AEs) were consistent with myelosuppression; nonhematologic AEs included fatigue, nausea, and diarrhea. The 30-day mortality was 8%. At the recommended monotherapy dose of 40 µg/kg, the complete remission + CRi rate was 28% (5 of 18 patients); 50% of patients who responded achieved minimal residual disease negativity. In patients across dose levels who achieved CR or CRi, the median time to full count recovery was 6.4 weeks for neutrophils (≥1000/µL) and 10.6 weeks for platelets (≥100 × 109/L). Vadastuximab talirine demonstrates activity and a tolerable safety profile as a single agent in patients with AML. The recommended monotherapy dose of vadastuximab talirine is 40 µg/kg. This trial was registered at www.clinicaltrials.gov as # NCT01902329. PMID:29196412

    To elucidate first-line managers' descriptions and reflections regarding their staff's access to empowering structures using Kanter's theory of structural empowerment. Good structural conditions within workplaces are essential to employees' wellbeing, and their ability to access empowerment structures is largely dependent on the management. Twenty-eight first-line managers in elderly care were interviewed. Deductive qualitative content analysis was used to analyse data. Managers perceived that staff had varying degrees of access to the empowering structures described in Kanter's theory - and that they possessed formal power in their roles as contact persons and representatives. The descriptions mostly started from the managers' own actions, although some started from the needs of staff members. All managers described their staff's access to the empowering structures in Kanter's theory as important, yet it seemed as though this was not always reflected on and discussed as a strategic issue. Managers could make use of performance and appraisal dialogues to keep up to date on staff's access to empowering structures. Recurrent discussions in the management group based on such current information could promote staff's access to power through empowering structures and make job definitions a strategic issue in the organisation. © 2014 John Wiley & Sons Ltd.

    The efficacy of the ALK inhibitor crizotinib as compared with standard chemotherapy as first-line treatment for advanced ALK-positive non-small-cell lung cancer (NSCLC) is unknown. We conducted an open-label, phase 3 trial comparing crizotinib with chemotherapy in 343 patients with advanced ALK-positive nonsquamous NSCLC who had received no previous systemic treatment for advanced disease. Patients were randomly assigned to receive oral crizotinib at a dose of 250 mg twice daily or to receive intravenous chemotherapy (pemetrexed, 500 mg per square meter of body-surface area, plus either cisplatin, 75 mg per square meter, or carboplatin, target area under the curve of 5 to 6 mg per milliliter per minute) every 3 weeks for up to six cycles. Crossover to crizotinib treatment after disease progression was permitted for patients receiving chemotherapy. The primary end point was progression-free survival as assessed by independent radiologic review. Progression-free survival was significantly longer with crizotinib than with chemotherapy (median, 10.9 months vs. 7.0 months; hazard ratio for progression or death with crizotinib, 0.45; 95% confidence interval [CI], 0.35 to 0.60; P<0.001). Objective response rates were 74% and 45%, respectively (P<0.001). Median overall survival was not reached in either group (hazard ratio for death with crizotinib, 0.82; 95% CI, 0.54 to 1.26; P=0.36); the probability of 1-year survival was 84% with crizotinib and 79% with chemotherapy. The most common adverse events with crizotinib were vision disorders, diarrhea, nausea, and edema, and the most common events with chemotherapy were nausea, fatigue, vomiting, and decreased appetite. As compared with chemotherapy, crizotinib was associated with greater reduction in lung cancer symptoms and greater improvement in quality of life. Crizotinib was superior to standard first-line pemetrexed-plus-platinum chemotherapy in patients with previously untreated advanced ALK-positive NSCLC. (Funded by

    We investigated the efficacy of entecavir, a cyclopentyl guanosine nucleoside analogue, as monoprophylaxis in patients with chronic hepatitis B who received a liver transplant. We studied data from 80 consecutive patients who received a liver transplant (47 from living donors and 33 from deceased donors) for hepatitis B-related disease and entecavir monotherapy as prophylaxis. None of the patients received hepatitis B immunoglobulin. Indications for transplant included decompensation from cirrhosis (27.5%), acute-on-chronic hepatitis B (47.5%), and hepatocellular carcinoma (25%). The median follow-up time was 26 months (range, 5-40 months). Before transplant, 33 patients were not on antiviral therapy and 47 were on oral therapy (18 had received less than 3 months of treatment). At the time of transplant, the median log HBV DNA level was 3.5 copies/mL (range, 1.54-8.81); 21 patients (26%) had undetectable levels of HBV DNA. The cumulative rate of hepatitis B surface antigen (HBsAg) loss was 86% and 91% after 1 and 2 years, respectively. Ten patients had reappearance of HBsAg. Eighteen patients (22.5%) were HBsAg positive at the time of their last examination; 17 of these had undetectable levels of HBV DNA, and the remaining patient had a low level of HBV DNA (217 copies/mL). There was no evidence of mutations at sites that confer resistance to entecavir among patients who were HBsAg positive. Although only 26% of patients had complete viral suppression at the time of transplant, 91% lost HBsAg, with 98.8% achieving undetectable levels of HBV DNA. A hepatitis B immunoglobulin-free regimen of entecavir monotherapy is effective after liver transplantation for chronic hepatitis B. Copyright © 2011 AGA Institute. Published by Elsevier Inc.

    To estimate the long-term cost-effectiveness of dapagliflozin versus acarbose as monotherapy in treatment-naïve patients with type 2 diabetes mellitus (T2DM) in China. The Cardiff Diabetes Model, an economic model designed to evaluate the cost-effectiveness of comparator therapies in diabetes was used to simulate disease progression and estimate the long-term effect of treatments on patients. Systematic literature reviews, hospital surveys, meta-analysis and indirect treatment comparison were conducted to obtain model-required patient profiles, clinical data and costs. Health insurance costs (2015¥) were estimated over 40 years from a healthcare payer perspective. Univariate and probabilistic sensitivity analyses were performed. The model predicted that dapagliflozin had lower incidences of cardiovascular events, hypoglycemia and mortality events, was associated with a mean incremental benefit of 0.25 quality-adjusted life-years (QALYs) and with a lower cost of ¥8,439 compared with acarbose. This resulted in a cost saving of ¥33,786 per QALY gained with dapagliflozin. Sensitivity analyses determined that the results are robust. Dapagliflozin is dominant compared with acarbose as monotherapy for Chinese T2DM patients, with a little QALY gain and lower costs. Dapagliflozin offers a well-tolerated and cost-effective alternative medication for treatment-naive patients in China, and may have a direct impact in reducing the disease burden of T2DM.

    The aim of this study was to compare the long-term efficacy of BCG monotherapy to alternating therapy of mitomycin C (MMC) and BCG in patients with carcinoma in situ (CIS). Between 1992 and 1997, 321 patients with CIS were randomized from Finland, Norway and Sweden in a prospective multicenter trial into two treatment groups. The alternating therapy comprised six weekly instillations of MMC 40 mg followed by 10 instillations of BCG (Connaught 120 mg) or MMC alternating monthly for 1 year. BCG monotherapy followed the same 6 + 10 schedule. Stratification was done by nationality and CIS category. Primary endpoints were time to first recurrence and time to progression. Secondary endpoints were disease-specific mortality and overall survival. The main statistical methods were the proportional subdistribution hazards model and Cox proportional hazards model with the cumulative incidence and Kaplan-Meier analyses. The median follow-up time was 9.9 years (maximum 19.9 years) in the BCG group and 8.9 years (maximum 20.3 years) in the alternating group. The risk of recurrence was significantly lower in the BCG group than in the alternating group (49 vs 59% at 15 years, respectively; hazard ratio 0.74, 95% confidence interval 0.54-1.00, p = 0.048). There were no significant differences in the other endpoints. Patients who progressed after 2 years were particularly prone to dying from bladder carcinoma. Younger patients performed worse than older ones. BCG monotherapy including monthly maintenance was effective and better than the alternating therapy. The risk of dying from bladder carcinoma after progression was high.

    Abstract Mitotane has been used for more than 5 decades as therapy for adrenocortical carcinoma (ACC). However its mechanism of action and the extent of tumor response remain incompletely understood. To date no cases of rapid and complete remission of metastatic ACC with mitotane monotherapy has been reported. A 52-year-old French Canadian man presented with metastatic disease 2 years following a right adrenalectomy for stage III nonsecreting ACC. He was started on mitotane which was well tolerated despite rapid escalation of the dose. The patient course was exceptional as he responded to mitotane monotherapy after only few months of treatment. Initiation of chemotherapy was not needed and he remained disease-free with good quality of life on low maintenance dose of mitotane during the following 10 years. A germline heterozygous TP53 exon 4 polymorphism c.215C>G (p. Pro72Arg) was found. Immunohistochemical stainings for IGF-2 and cytoplasmic β-catenin were positive. Advanced ACC is an aggressive disease with poor prognosis and the current therapeutic options remain limited. These findings suggest that mitotane is a good option for the treatment of metastatic ACC and might result in rapid complete remission in selected patients. PMID:27043680

    Objective To evaluate the efficacy and safety of conversion to lacosamide 400 mg/day monotherapy in adults with focal epilepsy. Methods This historical-controlled, double-blind study (NCT00520741) enrolled patients aged 16–70 years on stable doses of 1–2 antiepileptic drugs (AEDs) and experiencing 2–40 partial-onset seizures per 28 days during the 8-week prospective Baseline. Patients were randomized to lacosamide 400 or 300 mg/day (3:1 ratio), starting at 200 mg/day and titrated over 3 weeks to randomized dose. Patients then withdrew background AEDs over 6 weeks and entered a 10-week Monotherapy Phase. The primary assessment was the Kaplan-Meier–predicted percentage of patients on 400 mg/day in the full analysis set (FAS) meeting ≥1 predefined seizure-related exit criterion by day 112, compared with the historical-control threshold (65.3%). Results Four hundred twenty-five patients were enrolled and were eligible for safety analyses (400 mg/day, n = 319; 300 mg/day, n = 106). A total of 271 (63.8%) of 425 patients completed the Lacosamide Maintenance Phase (combined AED Withdrawal and Monotherapy Phases). Among 284 patients in the 400 mg/day group in the FAS, 82 (28.9%) met ≥1 exit criterion; the Kaplan-Meier–predicted exit percentage at day 112 for 400 mg/day (30.0%; 95% confidence interval [CI] 24.6–35.5%) was lower than the historical control. When exit events, withdrawal due to treatment-emergent adverse events (TEAEs), and withdrawal due to lack of efficacy were summed (n = 90), the predicted exit percentage (32.3%; 95% CI 26.8–37.8%) was also lower than the historical control. Most patients receiving 400 mg/day reported some improvement on the Clinical Global Impression of Change (75.4%) and Patient Global Impression of Change (74.3%). Overall, the most common (>10%) TEAEs were dizziness (24.0%), headache (14.4%), nausea (13.4%), convulsion (11.5%), somnolence (10.4%), and fatigue (10.1%); most (74.1%) were mild-to-moderate in intensity

    Background Although the effectiveness of treatment with ursodeoxycholic acid (UDCA) and fenofibrate for primary biliary cirrhosis (PBC) has been suggested by small trials, a systematic review to summarize the evidence has not yet been carried out. Methods A meta-analysis of all long-term randomized controlled trials comparing the combination of UDCA and fenofibrate with UDCA monotherapy was performed via electronic searches. Results Six trials, which included 84 patients, were assessed. Combination therapy with UDCA and fenofibrate was more effective than UDCA monotherapy in improving alkaline phosphatase (mean difference [MD]: −90.44 IU/L; 95% confidence interval [CI]: −119.95 to −60.92; P<0.00001), gamma-glutamyl transferase (MD: −61.58 IU/L; 95% CI: −122.80 to −0.35; P=0.05), immunoglobulin M (MD: −38.45 mg/dL; 95% CI: −64.38 to −12.51; P=0.004), and triglycerides (MD: −0.41 mg/dL; 95% CI: −0.82 to −0.01; P=0.05). However, their effects on pruritus (odds ratio [OR]: 0.39; 95% CI: 0.09–1.78; P=0.23), total bilirubin (MD: −0.05 mg/dL; 95% CI: −0.21 to 0.12; P=0.58), and alanine aminotransferase (MD: −3.31 IU/L; 95% CI: −14.60 to 7.97; P=0.56) did not differ significantly. This meta-analysis revealed no significant differences in the incidence of adverse events (OR: 0.21; 95% CI: 0.03–1.25; P=0.09) between patients treated with combination therapy and those treated with monotherapy. Conclusion In this meta-analysis, combination therapy with UDCA and fenofibrate was more effective in reducing alkaline phosphatase than UDCA monotherapy, but it did not improve clinical symptoms. There did not appear to be an increase in adverse events with combination therapy. PMID:26045661

    Recent studies showed that the non-adherence to the pharmacological therapy of patients affected by BPH-associated LUTS increased the risk of clinical progression of BPH. We examined the patients adherence to pharmacological therapy and its clinical consequences in men with BPH-associated LUTS looking at the differences between drug classes comparing mono vs combination therapy. A retrospective, population-based cohort study, using prescription administrative database and hospital discharge codes from a total of 1.5 million Italian men. Patients ≥ 40 years, administered alpha-blockers (AB) and 5alpha-reductase inhibitors (5ARIs), alone or in combination (CT), for BPH-associated LUTS were analyzed. The 1-year and long term adherence together with the analyses of hospitalization rates for BPH and BPH-related surgery were examined using multivariable Cox proportional hazards regression model and Pearson chi square test. Patients exposed to at least 6 months of therapy had a 1-year overall adherence of 29 % (monotherapy AB 35 %, monotherapy 5ARI 18 %, CT 9 %). Patient adherence progressively declined to 15 %, 8 % and 3 % for AB, 5ARI, and CT, respectively at the fifth year of follow up. Patients on CT had a higher discontinuation rate along all the follow-up compared to those under monotherapy with ABs or 5ARIs (all p < 0.0001). Moreover, CT was associated with a reduced risk of hospitalization for BPH-related surgery (HR 0.94; p < 0.0001) compared to AB monotherapy. Adherence to pharmacological therapy of BPH-associated LUTS is low and varies depending on drugs class. Patients under CT have a higher likelihood of discontinuing treatment for a number of reasons that should be better investigated. Our study suggests that new strategies aiming to increase patient's adherence to the prescribed treatment are necessary in order to prevent BPH progression.

    There are no evidence-based guidelines as to whether computed tomography (CT) or endoscopy should be selected as the first-line procedure when a nasal tumor is suspected in a dog or a cat and only one examination can be performed. Computed tomography and rhinoscopic features of 17 dogs and 5 cats with a histopathologically or cytologically confirmed nasal tumor were retrospectively reviewed. The level of suspicion for nasal neoplasia after CT and/or rhinoscopy was compared to the definitive diagnosis. Twelve animals underwent CT, 14 underwent rhinoscopy, and 4 both examinations. Of the 12 CT examinations performed, 11 (92%) resulted in the conclusion that a nasal tumor was the most likely diagnosis compared with 9/14 (64%) for rhinoscopies. Computed tomography appeared to be more reliable than rhinoscopy for detecting nasal tumors and should therefore be considered as the first-line procedure.

  4. The efficacy of intravenous sodium valproate and phenytoin as the first-line treatment in status epilepticus: a comparison study

    2013-01-01

    Background Status epilepticus (SE) is a serious neurological condition and requires prompt treatment. Sodium valproate has been used to treat SE successfully but its role as the first-line antiepileptic drug (AED) is still controversial. This study evaluated the efficacy of intravenous sodium valproate to determine if it is non-inferior to intravenous phenytoin in SE treatment. Methods Patients diagnosed as SE during 2003–2010 who were of an age of more than 15 years and received either intravenous sodium valproate or intravenous phenytoin as the first-line treatment were enrolled. Clinical characteristics and outcomes of SE were recorded and analyzed. The differences of outcomes between sodium valproate and phenytoin group were determined by descriptive statistics. Results During the study period, there were 37 and 17 SE patients who received intravenous phenytoin and intravenous sodium valproate as the first-line treatment, respectively. All patients received diazepam 10 mg intravenously as a rescue medication before starting the antiepileptic agents if uncontrolled except one patient in the sodium valproate group. There were no significant differences between the phenytoin and sodium valproate groups in all outcome variables including numbers of patients with clinically-controlled seizures, non-dependent patients, time to seizure control, and duration of hospitalization, and death. No serious cardiovasculars event such as hypotension occurred in either group. Conclusion Intravenous sodium valproate is non-inferior to intravenous phenytoin as the first-line treatment in SE with no significant cardiovascular compromises. PMID:23889906

    To evaluate the efficacy and toxicity of a combination of vinorelbine (VNB) and paclitaxel (PTX) as first-line chemotherapy in metastatic breast carcinoma (MBC). Between August 1995 and August 1997, 49 patients with untreated MBC received a regimen that consisted of VNB 30 mg/m2 in a 20-minute intravenous (IV) infusion on days 1 and 8 and PTX 135 mg/m2 in a 3-hour IV infusion (starting 1 hour after VNB) on day 1. Cycles were repeated every 28 days. The median age of the patients was 52 years, and 59% of patients were postmenopausal. Median performance status was 1. Dominant sites of disease were soft tissue in 6%, bone in 29%, and viscera in 65%. Objective responses were recorded in 27 of 45 assessable patients (60%; 95% confidence interval, 46% to 74%). Complete remissions occurred in three patients (7%), and partial remissions occurred in 24 patients (53%). No change was recorded in 12 patients (27%), and progressive disease occurred in six patients (13%). The median time to treatment failure was 7 months, and median survival duration was 17 months. The limiting toxicity was myelosuppression, mainly leukopenia in 49 patients (100%) (grade 1 to grade 2, four patients; grade 3, 30 patients; and grade 4, 15 patients). Neutropenia was observed in 100% of patients (grade 1 to grade 2, three patients; grade 3, 11 patients; grade 4, 35 patients). Two treatment-related deaths due to febrile neutropenia were observed in patients with massive liver involvement. Peripheral neurotoxicity developed in 33 patients (67%) (grade 1, 25 patients; grade 2, eight patients); there were no grade 3 or grade 4 episodes. The combination of VNB-PTX showed significant activity as first-line chemotherapy for patients with MBC. Myelosuppression was the dose-limiting side effect, whereas neurotoxicity was mild to moderate.

    Many physicians believe that the most effective way to treat chronic urticaria is to take a nonsedating second-generation H1 -antihistamine in the morning and a sedating first-generation H1 -antihistamine, usually hydroxyzine, at night to enhance sleep. But is this belief well founded? To test this belief by comparing the effectiveness and prevalence of unwanted sedative effects when treating patients with chronic spontaneous urticaria (CSU) with levocetirizine 15 mg daily plus hydroxyzine 50 mg at night (levocetirizine plus hydroxyzine) vs. levocetirizine 20 mg daily (levocetirizine monotherapy). In this randomized, double-blind, cross-over study, 24 patients with difficult-to-treat CSU took levocetirizine plus hydroxyzine or levocetirizine monotherapy for periods of 5 days each. At the end of each treatment period, assessments were made of quality of life (Chronic Urticaria Quality of Life Questionnaire, CU-Q2 oL), severity of urticaria symptoms (Urticaria Activity Score, UAS), sleep disturbance during the night and daytime somnolence. Both treatments significantly decreased UAS, night-time sleep disturbances and CU-Q2 oL scores (P < 0·001) without significant differences between the two. Compared with baseline, daytime somnolence was significantly reduced by levocetirizine monotherapy (P = 0·006) but not by levocetirizine plus hydroxyzine (P = 0·218). Direct comparison of the two treatment modalities in terms of daytime somnolence favoured levocetirizine monotherapy (P = 0·026). The widespread belief that sleep is aided by the addition of a sedating first-generation H1 -antihistamine, usually hydroxyzine, at night is not supported. These results are in line with the urticaria guidelines, which state that first-line treatment for urticaria should be new-generation, nonsedating H1 -antihistamines only. © 2014 The Authors.

    Gastric cancer (GC) is the most common gastrointestinal malignant tumor, with a gradual increasing incidence throughout the world. Mostly GC is diagnosed in its late stage. To date, there is no usable standardized treatment regimen for patients with advanced GC. Apatinib mesylate, small-molecule vascular endothelial growth factor receptor-2 (VEGFR-2) tyrosine kinase inhibitor (TKI), has been approved as third-line treatment for patients with advanced gastric adenocarcinoma in China, October, 2014. Till now, there is no case report about apatinib as first-line treatment for patients with advanced GC in literature. We present an 83-year-old Chinese man with advanced gastric adenocarcinoma, who received apatinib as first-line option and obtained clinical benefit within 2 weeks. The lung metastases disappeared completely and the liver metastases shrank significantly. The patient's progression-free survival was 163 days and overall survival was 201 days. This paper reviews and discusses apatinib as a new targeted drug for patients with advanced GC by comparison with other effective molecular-targeted therapy. © 2016 John Wiley & Sons Australia, Ltd.

    Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis. The Oral Rheumatoid Arthritis triaL (ORAL) Strategy aimed to assess the comparative efficacy of tofacitinib monotherapy, tofacitinib plus methotrexate, and adalimumab plus methotrexate for the treatment of rheumatoid arthritis in patients with a previous inadequate response to methotrexate. ORAL Strategy was a 1 year, double-blind, phase 3b/4, head-to-head, non-inferiority, randomised controlled trial in patients aged 18 years or older with active rheumatoid arthritis despite methotrexate therapy. Patients were randomly assigned (1:1:1) to receive oral tofacitinib (5 mg twice daily) monotherapy, oral tofacitinib (5 mg twice daily) plus methotrexate, or subcutaneous adalimumab (40 mg every other week) plus methotrexate at 194 centres in 25 countries. Eligible patients received live zoster vaccine at investigators' discretion. The primary endpoint was the proportion of patients who attained an American College of Rheumatology response of at least 50% (ACR50) at month 6 in the full analysis set (patients who were randomly assigned to a group and received at least one dose of the study treatment). Non-inferiority between groups was shown if the lower bound of the 98·34% CI of the difference between comparators was larger than -13·0%. This trial is registered with ClinicalTrials.gov, number NCT02187055. 1146 patients received treatment (384 had tofacitinib monotherapy; 376 had tofacitinib and methotrexate; and 386 had adalimumab and methotrexate). At 6 months, ACR50 response was attained in 147 (38%) of 384 patients with tofacitinib monotherapy, 173 (46%) of 376 patients with tofacitinib and methotrexate, and 169 (44%) of 386 patients with adalimumab and methotrexate. Non-inferiority was declared for tofacitinib and methotrexate versus adalimumab and methotrexate (difference 2% [98·34% CI -6 to 11]) but not for tofacitinib monotherapy versus either adalimumab and methotrexate (-6

    The efficacy of EGFR tyrosine kinase inhibitors (TKIs) varies among different EGFR mutations. Here, we directly compared the efficacy of first-line TKIs to chemotherapy for non-small cell lung cancer (NSCLC) patients with the L858R mutation. The progression-free survival (PFS) for patients receiving TKIs as first-line therapy was longer than those who received chemotherapy (hazard ratio [HR]: 0.44, P < 0.001). Subgroup analyses showed that first-line TKI therapy resulted in longer PFS among non-smokers (HR: 0.41, P < 0.001), male (HR: 0.49, P = 0.002), female (HR: 0.39, P < 0.001), and patients with adenocarcinoma histology (HR: 0.41, P < 0.001). However, among patients with non-adenocarcinoma histology (HR: 1.11, P = 0.824) and those who used to smoke (HR: 0.55, P = 0.093), first-line TKI therapy failed to demonstrate statistically longer PFS compared to chemotherapy. Our results demonstrated that for patients with L858R mutation, first-line TKI therapy provided better survival benefits. However, among non-adenocarcinoma patients and those who used to smoke, the PFS in cohorts receiving first-line chemotherapy or TKI were not significantly different. The results of the current study will be helpful for decision-making in the treatment of patients with L858R mutation.

    To compare the costs of first-line treatment with panitumumab + FOLFOX in comparison to cetuximab + FOLFIRI among patients with wild-type (WT) RAS metastatic colorectal cancer (mCRC) in the US. A cost-minimization model was developed assuming similar treatment efficacy between both regimens. The model estimated the costs associated with drug acquisition, treatment administration frequency (every 2 weeks for panitumumab, weekly for cetuximab), and incidence of infusion reactions. Average anti-EGFR doses were calculated from the ASPECCT clinical trial, and average doses of chemotherapy regimens were based on product labels. Using the medical component of the consumer price index, adverse event costs were inflated to 2014 US dollars, and all other costs were reported in 2014 US dollars. The time horizon for the model was based on average first-line progression-free survival of a WT RAS patient, estimated from parametric survival analyses of PRIME clinical trial data. Relative to cetuximab + FOLFIRI in the first-line treatment of WT RAS mCRC, the cost-minimization model demonstrated lower projected drug acquisition, administration, and adverse event costs for patients who received panitumumab + FOLFOX. The overall cost per patient for first-line treatment was $179,219 for panitumumab + FOLFOX vs $202,344 for cetuximab + FOLFIRI, resulting in a per-patient saving of $23,125 (11.4%) in favor of panitumumab + FOLFOX. From a value perspective, the cost-minimization model supports panitumumab + FOLFOX instead of cetuximab + FOLFIRI as the preferred first-line treatment of WT RAS mCRC patients requiring systemic therapy.

    2014-01-01

    Background The most important symptom as well as one of the major diagnostic criteria for eczema is itch. Although oral antihistamines continue to be prescribed for people with eczema, it is unclear if they are effective and safe in relieving itch and skin lesions. We sought to evaluate the available evidence on effectiveness of oral antihistamines (H1 antagonists) as monotherapy in children and adults with eczema. Methods Searches included 10 databases and trial registers as well as conference proceedings (January 2014). Randomised controlled trials that assessed the effects of oral H1 antihistamines as monotherapy in children and adults with eczema were included. Results Our searches retrieved 757 references, but no randomised controlled trial met our inclusion criteria. Most studies allowed concomitant treatments, making the assessment of the individual effects of oral H1 antihistamines impossible. Conclusions There is currently no high-level evidence to support or refute the efficacy or safety of oral H1 antihistamines used as monotherapy for eczema. A further review of studies that assesses the effects of oral H1 antihistamines as ‘add-on’ therapy together with concomitant treatments is warranted to determine the beneficial effects of this group of medications in the treatment of eczema.

    The vertebrate Scube (Signal peptide, CUB, and EGF-like domain-containing protein) family consists of three independent members, Scube1–3, which encode secreted cell surface-associated membrane glycoproteins. Limited information about the general function of this gene family is available, and their roles during adulthood. Here, we present the first Scube3 mutant mouse line (Scube3N294K/N294K), which clearly shows phenotypic alterations by carrying a missense mutation in exon 8, and thus contributes to our understanding of SCUBE3 functions. We performed a detailed phenotypic characterization in the German Mouse Clinic (GMC). Scube3N294K/N294K mutants showed morphological abnormalities of the skeleton, alterations of parameters relevant for bone metabolism, changes in renal function, and hearing impairments. These findings correlate with characteristics of the rare metabolic bone disorder Paget disease of bone (PDB), associated with the chromosomal region of human SCUBE3. In addition, alterations in energy metabolism, behavior, and neurological functions were detected in Scube3N294K/N294K mice. The Scube3N294K/N294K mutant mouse line may serve as a new model for further studying the effect of impaired SCUBE3 gene function. PMID:27815347

    Splenectomy is considered as one of the first-line treatments for symptomatic patients with splenic marginal zone lymphoma (SMZL). Between 1997 and 2012, 100 hepatitis C virus-negative patients with SMZL were treated by splenectomy as first-line treatment. At 6 months, all patients but three recovered from all cytopenias. The median lymphocyte count at 6 months and 1 year was 11.51 × 10(9)/L and 6.9 × 10(9)/L, respectively. Median progression-free survival (PFS) was 8.25 years. The 5-year and 10-year overall survival (OS) rates were 84% and 67%, respectively. Histological transformation occurred in 11% of patients, and was the only parameter significantly associated with a shorter time to progression (p = 0.0001). Significant prognostic factors for OS were age (p = 0.0356) and histological transformation (p = 0.0312). In this large retrospective cohort, we confirmed that splenectomy as first-line treatment in patients with SMZL corrected cytopenias and lymphocytosis within the first year and was associated with a good PFS.

    The aim of this observational, nonrandomized study was to compare the effects of 12 months of monthly minodronate (MIN; 50 mg/month) monotherapy and MIN combination therapy with vitamin K2 (VK; 45 mg/day) or eldecalcitol (ELD; 0.75 μg/day) in treatment-naïve patients with primary osteoporosis. Patients (n = 193; 178 postmenopausal women and 15 men; mean age 71.6 years) were treated with (1) MIN monotherapy (n = 63), (2) MIN plus VK combination therapy (n = 50), or (3) MIN plus ELD combination therapy (n = 80) for 12 months. Changes in bone mineral density (BMD) and the levels of serum bone turnover markers were monitored. No significant difference was observed in baseline BMD among the three groups. After 12 months, BMD increased by 2.93, 4.65, and 6.55 % in the lumbar spine, 0.66, 2.57, and 3.42 % in the total hip, and 0.05, 2.06, and 3.58 % in the femoral neck in groups 1, 2, and 3, respectively. The BMD increase induced by MIN plus ELD combination therapy was significantly greater than that induced by MIN monotherapy in the lumbar spine (P = 0.0002), total hip (P = 0.003), and femoral neck (P = 0.004), and also that induced by MIN plus VK combination therapy in the lumbar spine (P = 0.03). MIN plus ELD combination therapy compared with MIN monotherapy resulted in a greater decrease in serum procollagen type I N-terminal propeptide levels (-37.4 % vs -54.6 %; P = 0.001) and tartrate-resistant acid phosphatase isoform 5b levels (-41.1 % vs -52.9 %; P = 0.009) at 3 months, and a greater decrease in procollagen type I N-terminal propeptide levels (-64.3 % vs -50.3 %; P = 0.03) and a decrease in intact parathyroid hormone levels (-12.3 % vs 14.0 %; P = 0.01) at 12 months. Combination therapy with MIN and VK or ELD for 12 months showed additive effects in decreasing the levels of bone turnover markers compared with MIN monotherapy, whereas MIN plus ELD combination therapy resulted in the highest BMD increase compared

    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.

    Non-selective beta blockers (NSBBs) are currently the only accepted regimen for preventing portal hypertension (PHT)-related complications. However, the effect of NSBBs is insufficient in many cases. Bacterial translocation (BT) is one of the aggravating factors of PHT in cirrhosis; therefore, selective intestinal decontamination by rifaximin is a possible therapeutic option for improving PHT. We investigated whether the addition of rifaximin to propranolol therapy can improve hepatic venous pressure gradient (HVPG) response. Sixty-four cirrhosis patients were randomly assigned to propranolol monotherapy (n=48) versus rifaximin and propranolol combination therapy (n=16). Baseline and post-treatment HVPG values, BT-related markers (lipopolysaccharide [LPS], LPS-binding protein [LBP], interleukin-6 [IL-6], and tumor necrosis factor α [TNF-α]), serological data, and adverse event data were collected. HVPG response rate was the primary endpoint. Combination therapy was associated with better HVPG response rates than monotherapy (56.2% vs 87.5%, p=0.034). In combination therapy, posttreatment BT-related markers were significantly decreased (LPS, p=0.005; LBP, p=0.005; IL-6, p=0.005; TNF-α, p=0.047). Rifaximin combination therapy showed an additive effect in improving PHT compared to propranolol monotherapy. These pilot data suggest that the addition of rifaximin to NSBBs could be a good therapeutic option for overcoming the limited effectiveness of NSBBs.

    Low levels of 25(OH) vitamin D [25(OH)VitD] have been recognized as a new cardiovascular disease (CVD) risk factor. Statins seem to increase 25(OH)VitD concentration. To investigate whether combined treatment with the usual dose of rosuvastatin plus fenofibrate or omega-3 fatty acids would increase 25(OH)VitD levels compared with the high-dose rosuvastatin monotherapy in participants with mixed dislipidemia. We randomly allocated 60 patients with mixed dyslipidemia (low-density lipoprotein cholesterol: >160 mg/dL plus triglycerides: >200 mg/dL) to receive rosuvastatin 40 mg (n = 22), rosuvastatin 10 mg plus fenofibrate 200 mg (n = 21), or rosuvastatin 10 mg plus omega-3 fatty acids 2 g (n = 17) daily for 3 months. Our primary end point was changes in the levels of serum 25(OH)VitD. Rosuvastatin monotherapy was associated with a 53% increase in 25(OH)VitD (from 14.6 [1.0-38.0] to 17.8 [5.3-49.6] ng/mL; P = .000). Rosuvastatin plus micronized fenofibrate and rosuvastatin plus omega-3 fatty acids were associated with increases of 64% (from 14.1 [1.0-48.0] to 18.4 [6.7-52.4] ng/mL, P = .001) and 61% (from 10.4 [6.6-38.4] to 14.0 [9.6-37.6] ng/mL, P = .04), respectively. The changes in 25(OH)VitD after treatment were comparable in the 3 groups. High-dose rosuvastatin monotherapy and the usual dose of rosuvastatin plus fenofibrate or omega-3 fatty acids are associated with significant and similar increases in the 25(OH)VitD levels. This increase may be relevant in terms of CVD risk prevention.

    To estimate the risks of radiation-induced rectal and bladder cancers following low dose rate (LDR) and high dose rate (HDR) brachytherapy as monotherapy for localised prostate cancer and compare to external beam radiotherapy techniques. LDR and HDR brachytherapy monotherapy plans were generated for three prostate CT datasets. Second cancer risks were assessed using Schneider's concept of organ equivalent dose. LDR risks were assessed according to a mechanistic model and a bell-shaped model. HDR risks were assessed according to a bell-shaped model. Relative risks and excess absolute risks were estimated and compared to external beam techniques. Excess absolute risks of second rectal or bladder cancer were low for both LDR (irrespective of the model used for calculation) and HDR techniques. Average excess absolute risks of rectal cancer for LDR brachytherapy according to the mechanistic model were 0.71 per 10,000 person-years (PY) and 0.84 per 10,000 PY respectively, and according to the bell-shaped model, were 0.47 and 0.78 per 10,000 PY respectively. For HDR, the average excess absolute risks for second rectal and bladder cancers were 0.74 and 1.62 per 10,000 PY respectively. The absolute differences between techniques were very low and clinically irrelevant. Compared to external beam prostate radiotherapy techniques, LDR and HDR brachytherapy resulted in the lowest risks of second rectal and bladder cancer. This study shows both LDR and HDR brachytherapy monotherapy result in low estimated risks of radiation-induced rectal and bladder cancer. LDR resulted in lower bladder cancer risks than HDR, and lower or similar risks of rectal cancer. In absolute terms these differences between techniques were very small. Compared to external beam techniques, second rectal and bladder cancer risks were lowest for brachytherapy. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    There are no evidence-based guidelines as to whether computed tomography (CT) or endoscopy should be selected as the first-line procedure when a nasal tumor is suspected in a dog or a cat and only one examination can be performed. Computed tomography and rhinoscopic features of 17 dogs and 5 cats with a histopathologically or cytologically confirmed nasal tumor were retrospectively reviewed. The level of suspicion for nasal neoplasia after CT and/or rhinoscopy was compared to the definitive diagnosis. Twelve animals underwent CT, 14 underwent rhinoscopy, and 4 both examinations. Of the 12 CT examinations performed, 11 (92%) resulted in the conclusion that a nasal tumor was the most likely diagnosis compared with 9/14 (64%) for rhinoscopies. Computed tomography appeared to be more reliable than rhinoscopy for detecting nasal tumors and should therefore be considered as the first-line procedure. PMID:25694669

    Background To better understand the need for paediatric second-line antiretroviral therapy (ART), an ART management survey and a cross-sectional analysis of second-line ART use were conducted in the TREAT Asia Paediatric HIV Observational Database and the IeDEA Southern Africa (International Epidemiologic Databases to Evaluate AIDS) regional cohorts. Methods Surveys were conducted in April 2009. Analysis data from the Asia cohort were collected in March 2009 from 12 centres in Cambodia, India, Indonesia, Malaysia, and Thailand. Data from the IeDEA Southern Africa cohort were finalized in February 2008 from 10 centres in Malawi, Mozambique, South Africa and Zimbabwe. Results Survey responses reflected inter-regional variations in drug access and national guidelines. A total of 1301 children in the TREAT Asia and 4561 children in the IeDEA Southern Africa cohorts met inclusion criteria for the cross-sectional analysis. Ten percent of Asian and 3.3% of African children were on second-line ART at the time of data transfer. Median age (interquartile range) in months at second-line initiation was 120 (78-145) months in the Asian cohort and 66 (29-112) months in the southern African cohort. Regimens varied, and the then current World Health Organization-recommended nucleoside reverse transcriptase combination of abacavir and didanosine was used in less than 5% of children in each region. Conclusions In order to provide life-long ART for children, better use of current first-line regimens and broader access to heat-stable, paediatric second-line and salvage formulations are needed. There will be limited benefit to earlier diagnosis of treatment failure unless providers and patients have access to appropriate drugs for children to switch to. PMID:21306608

    Recent studies have identified that Interleukin (IL)-23/IL-17 axis plays crucial role in pathogenesis of inflammation and bone destruction. IL-23 is thought to promote joint destruction in arthritis by stimulating Th17 cells. IL-23 directly mediates bone loss by inducing osteoclastogenesis and receptor activator of kappa B ligand (RANKL) expression in T cells. IL-23 also promotes tartrate-resistant acid phosphatase (TRAP) activity of osteoclast in osteoblast-osteoclast co-culture. The role of IL-23 has not been studied in estrogen deficiency induced bone loss. Here, we study the effect of IL-23 neutralization in ovariectomized (Ovx) estrogen deficient mice on various immune and skeletal parameters. We also determine whether the combination of anti-IL-23 and anti-IL17 has enhanced osteoprotective effects compared to monotherapies. Treatment of anti-IL-23 and its combination with anti-IL-17 suppressed Th17 cell differentiation and promoted development of T regulatory cells. Anti-IL-23 and its combination with anti-IL-17 prevented bone loss. However, the individual monotherapies of anti-IL-23 and anti-IL-17 were more effective than combination therapy. Treatment of IL-17 and IL-23 cytokines to bone marrow stromal cells led to increased differentiation towards osteoblast lineage. Double neutralization of IL-23 and IL-17 might be inhibiting this phenomenon thus producing less potent effects. Our studies thus support bone protective effects of anti-IL-23 and that the monotherapies of neutralizing antibodies against IL-17 and IL-23 may be a more accepted mode of treatment in management of post-menopausal bone loss rather than combination therapy.

    Sparing of antiretroviral drug classes could reduce the toxicity and cost of maintenance treatment for HIV infection. To evaluate the non-inferiority of efficacy and the safety of lopinavir/ritonavir (r) monotherapy versus a single-tablet regimen of efavirenz, emtricitabine and tenofovir (EFV/FTC/TDF) over 2 years. Adults on stable ART with plasma HIV-1 RNA viral load <50 copies/mL for the past 12 months and no documented treatment failure were randomized to receive either lopinavir/r or EFV/FTC/TDF for 2 years. The primary endpoint was the proportion of patients without treatment failure at week 96 (viral load <50 copies/mL at week 96, confirmed at week 98), without study treatment discontinuation, a new AIDS-defining illness, or death. In the ITT analysis, the primary endpoint was reached by, respectively, 64% and 71% of patients in the lopinavir/r (n = 98) and EFV/FTC/TDF arms (n = 97), yielding a difference of -6.8% (lower limit of the 95% two-sided CI: -19.9%). Sanger and UltraDeep sequencing showed the occurrence of PI mutations in the lopinavir/r arm (n = 4) and of NNRTI and/or NRTI mutations in the EFV/FTC/TDF arm (n = 2). No unexpected serious clinical events occurred. Lopinavir/r monotherapy cannot be considered non-inferior to EFV/FTC/TDF. PI resistance rarely emerged in the lopinavir/r arm and did not undermine future PI options. Two years of lopinavir/r monotherapy had no deleterious clinical impact when compared with EFV/FTC/TDF.

    In the Port Moresby General Hospital, the Chemical Pathology Department assays both thyroid stimulating hormone (TSH) and free thyroxine (FT4) on all requests for a thyroid function test (TFT). The cost of assaying both tests is obviously higher than either test alone. In order to minimize the cost of a TFT we aimed to determine if TSH or FT4 alone as a first-line test would be adequate in assessing the thyroid hormone status of patients. We analyzed TFT records from January 1996 to May 2000 in the Port Moresby General Hospital. A total of 3089 TSH and 2867 FT4 were assayed at an annual reagent cost of Papua New Guinea kina 14,500. When TSH alone is used as a first-line test at the Port Moresby General Hospital, the biochemical status of 95% of patients will be appropriately categorized as euthyroidism, hypothyroidism or hyperthyroidism with only 5% discrepant (ie, normal TSH with abnormal FT4) results. In contrast, using FT4 alone as a first-line test correctly classifies only 84% of TFTs. Euthyroid status is observed in 50% of patients and FT4 assays on these samples will be excluded appropriately if a TSH-only protocol is adopted. Furthermore, we will save a quarter of the yearly cost of TFTs on reagents alone by performing TSH only. We conclude that TSH alone is an adequate first-line thyroid function test in Papua New Guinea and when it is normal no further FT4 test is necessary unless clinically indicated.

    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.

    In April 2010, tenofovir and abacavir replaced stavudine in public sector first-line antiretroviral therapy (ART) for children under 20 years old in South Africa. The association of both abacavir and tenofovir with fewer side effects and toxicities compared to stavudine could translate to increased durability of tenofovir or abacavir-based regimens. We evaluated changes over time in regimen durability for paediatric patients 3-19 years of age at eight public sector clinics in Johannesburg, South Africa. Cohort analysis of treatment-naïve, non-pregnant paediatric patients from 3 to 19 years old initiated on ART between April 2004 and December 2013. First-line ART regimens before April 2010 consisted of stavudine or zidovudine with lamivudine and either efavirenz or nevirapine. Tenofovir and/or abacavir was substituted for stavudine after April 2010 in first-line ART. We evaluated the frequency and type of single-drug substitutions, treatment interruptions and switches to second-line therapy. Fine and Gray competing risk regression models were used to evaluate the association of antiretroviral drug type with single-drug substitutions, treatment interruptions and second-line switches in the first 24 months on treatment. Three hundred and ninety-eight (15.3%) single-drug substitutions, 187 (7.2%) treatment interruptions and 86 (3.3%) switches to second-line therapy occurred among 2602 paediatric patients over 24-months on ART. Overall, the rate of single-drug substitutions started to increase in 2009, peaked in 2011 at 25% and then declined to 10% in 2013, well after the integration of tenofovir into paediatric regimens; no patients over the age of 3 were initiated on abacavir for first-line therapy. Competing risk regression models showed patients on zidovudine or stavudine had upwards of a fivefold increase in single-drug substitution vs. patients initiated on tenofovir in the first 24 months on ART. Older adolescents also had a two- to threefold increase in

    Objective To estimate the long-term cost-effectiveness of dapagliflozin versus acarbose as monotherapy in treatment-naïve patients with type 2 diabetes mellitus (T2DM) in China. Methods The Cardiff Diabetes Model, an economic model designed to evaluate the cost-effectiveness of comparator therapies in diabetes was used to simulate disease progression and estimate the long-term effect of treatments on patients. Systematic literature reviews, hospital surveys, meta-analysis and indirect treatment comparison were conducted to obtain model-required patient profiles, clinical data and costs. Health insurance costs (2015¥) were estimated over 40 years from a healthcare payer perspective. Univariate and probabilistic sensitivity analyses were performed. Results The model predicted that dapagliflozin had lower incidences of cardiovascular events, hypoglycemia and mortality events, was associated with a mean incremental benefit of 0.25 quality-adjusted life-years (QALYs) and with a lower cost of ¥8,439 compared with acarbose. This resulted in a cost saving of ¥33,786 per QALY gained with dapagliflozin. Sensitivity analyses determined that the results are robust. Conclusion Dapagliflozin is dominant compared with acarbose as monotherapy for Chinese T2DM patients, with a little QALY gain and lower costs. Dapagliflozin offers a well-tolerated and cost-effective alternative medication for treatment-naive patients in China, and may have a direct impact in reducing the disease burden of T2DM.

    Platinum-based doublet chemotherapy is the treatment of choice for patients with non-small cell lung cancer (NSCLC); however, the role of a platinum-based doublet as second-line therapy after failure of an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) for NSCLC patients has not yet been elucidated. The purpose of this study was to compare the clinical efficacy of pemetrexed versus a platinum-based doublet as second-line therapy after failure of EGFR TKI used as first-line therapy for NSCLC patients with EGFR mutations. We designed a multicenter retrospective cohort study of 314 NSCLC patients with EGFR mutations who received an EGFR TKI as first-line palliative chemotherapy. Our analysis included 83 patients who failed EGFR TKI therapy and received second-line cytotoxic chemotherapy. Forty-six patients were treated using a platinum-based doublet and 37 patients were treated using singlet pemetrexed. The overall response rates of patients receiving a platinum-based doublet and patients receiving pemetrexed were17.4% and 32.4%, respectively (p=0.111). The median progression-free survival (PFS) of patients receiving pemetrexed was significantly longer than that of patients receiving a platinum-based doublet (4.2 months vs. 2.7 months, respectively; p=0.008). The hazard ratio was 0.54 (95% confidence interval, 0.34 to 0.86; p=0.009). Our retrospective analysis found that second-line pemetrexed singlet therapy provided significantly prolonged PFS compared to second-line platinum-based doublet chemotherapy for NSCLC patients with EGFR mutations who failed first-line EGFR TKI. Conduct of prospective studies for confirmation of our results is warranted.

    Immune suppression is a crucial pillar for treatment of aplastic anemia. Cyclosporine monotherapy is an easily available, affordable therapeutic option with good safety profile. This prospective study was conducted over a period of 2 years from June 2012 to July 2014. The diagnosis and response to treatment of aplastic anemia was established as per published criteria. Follow up was done at 3 and 6 months in order to assess the response. 57 patients of acquired aplastic anemia with median age of 37 years (6 to 81 years) were included in the study. 35 (62 %) cases were severe aplastic anemai, 16 (28 %) non severe aplastic anemia and 6 (10 %) were very severe aplastic anemia. At 3 months overall response rate (OR) was 7 (14 %) and at 6 months the OR rate of 11 (19.6 %) was achieved. Transiently raised creatinine, liver function abnormality and gum hypertrophy were the main side effects observed in this cohort. Oral cyclosporine monotherapy at dose of 5 mg/kg/day is a relatively safe treatment option for resource poor patients with aplastic anemia.

    Purpose The addition of bevacizumab to fluorouracil-based chemotherapy is a standard of care for previously untreated metastatic colorectal cancer. Continuation of bevacizumab beyond progression is an accepted standard of care based on a 1.4-month increase in median overall survival observed in a randomized trial. No United States–based cost-effectiveness modeling analyses are currently available addressing the use of bevacizumab in metastatic colorectal cancer. Our objective was to determine the cost effectiveness of bevacizumab in the first-line setting and when continued beyond progression from the perspective of US payers. Methods We developed two Markov models to compare the cost and effectiveness of fluorouracil, leucovorin, and oxaliplatin with or without bevacizumab in the first-line treatment and subsequent fluorouracil, leucovorin, and irinotecan with or without bevacizumab in the second-line treatment of metastatic colorectal cancer. Model robustness was addressed by univariable and probabilistic sensitivity analyses. Health outcomes were measured in life-years and quality-adjusted life-years (QALYs). Results Using bevacizumab in first-line therapy provided an additional 0.10 QALYs (0.14 life-years) at a cost of $59,361. The incremental cost-effectiveness ratio was $571,240 per QALY. Continuing bevacizumab beyond progression provided an additional 0.11 QALYs (0.16 life-years) at a cost of $39,209. The incremental cost-effectiveness ratio was $364,083 per QALY. In univariable sensitivity analyses, the variables with the greatest influence on the incremental cost-effectiveness ratio were bevacizumab cost, overall survival, and utility. Conclusion Bevacizumab provides minimal incremental benefit at high incremental cost per QALY in both the first- and second-line settings of metastatic colorectal cancer treatment. PMID:25691669

    Purpose Paclitaxel, ifosfamide, and cisplatin (TIP) achieved complete responses (CRs) in two thirds of patients with advanced germ cell tumors (GCTs) who relapsed after first-line chemotherapy with cisplatin and etoposide with or without bleomycin. We tested the efficacy of first-line TIP in patients with intermediate- or poor-risk disease. Patients and Methods In this prospective, multicenter, single-arm phase II trial, previously untreated patients with International Germ Cell Cancer Collaborative Group poor-risk or modified intermediate-risk GCTs received four cycles of TIP (paclitaxel 240 mg/m2 over 2 days, ifosfamide 6 g/m2 over 5 days with mesna support, and cisplatin 100 mg/m2 over 5 days) once every 3 weeks with granulocyte colony-stimulating factor support. The primary end point was the CR rate. Results Of the first 41 evaluable patients, 28 (68%) achieved a CR, meeting the primary efficacy end point. After additional accrual on an extension phase, total enrollment was 60 patients, including 40 (67%) with poor risk and 20 (33%) with intermediate risk. Thirty-eight (68%) of 56 evaluable patients achieved a CR and seven (13%) achieved partial responses with negative markers (PR-negative) for a favorable response rate of 80%. Five of seven achieving PR-negative status had seminoma and therefore did not undergo postchemotherapy resection of residual masses. Estimated 3-year progression-free survival and overall survival rates were 72% (poor risk, 63%; intermediate risk, 90%) and 91% (poor risk, 87%; intermediate risk, 100%), respectively. Grade 3 to 4 toxicities consisted primarily of reversible hematologic or electrolyte abnormalities, including neutropenic fever in 18%. Conclusion TIP demonstrated efficacy as first-line therapy for intermediate- and poor-risk GCTs with an acceptable safety profile. Given higher rates of favorable response, progression-free survival, and overall survival compared with prior first-line studies, TIP warrants further study in

  12. Should doxylamine-pyridoxine be used for nausea and vomiting of pregnancy?

    Persaud, Navindra; Chin, Jessica; Walker, Mark

    2014-04-01

    Doxylamine-pyridoxine is the first-line agent for the treatment of nausea and vomiting of pregnancy (NVP) according to Canadian guidelines, and this combination is commonly prescribed to pregnant women. There is limited evidence that doxylamine-pyridoxine is more effective than pyridoxine alone. There is stronger support for the safety of pyridoxine monotherapy than for the combination of doxylamine-pyridoxine during pregnancy, and some conflicting evidence links doxylamine-pyridoxine use to pyloric stenosis and childhood malignancies. The role of doxylamine-pyridoxine as the first-line pharmacological treatment for NVP in Canada should be reconsidered.

    Many patients previously using darunavir/ritonavir (DRV/r) (800/100mg) have switched to darunavir/cobicistat (DRV/C) (800/150 mg) either as part of triple therapy (ART) or as monotherapy with DRV (mDRV). The latter approach continues to be used in some countries for patients receiving long-term treatment. However, to date, the behaviour of DRV/C in the seminal compartment has not been analysed. This study explores how the combination behaves in monotherapy, with respect to the control of viral load and seminal quality. To this end, we studied 20 patients who were treated with mDRV/C after previous treatment with mDRV/r for at least 24 weeks. A viral load control in seminal plasma similar to that published in the literature was observed after 24 weeks of treatment with mDRV/C (viral load positivity in 20% of patients). Similarly, semen quality was confirmed (70% normozoospermic) in patients treated with this formulation, as has previously been reported for ART and mDRV/r. The DRV levels measured in seminal plasma were above EC50, regardless of whether the seminal viral load was positive or negative. We conclude that this mDRV/C co-formulation behaves like mDRV/r in seminal plasma in terms of viral load control and semen quality. PMID:29689065

    An altered perfusion of the optic nerve head has been proposed as a pathogenic factor in glaucoma. The aim of this study was to evaluate the correlation between ocular pulse amplitude (OPA), measured by Dynamic contour tonometer (DCT) and colour Doppler imaging (CDI) of the arteric retrobulbar vessels. Twenty patients older than 50 years were examined, and divided into two equal groups. The first group comprised of patients with normal tension glaucoma treated with topical antiglaucomatous therapy, and the second group included patients with ocular hypertension and glaucoma suspicious without any antiglaucomatous therapy. Ocular pulse amplitude (OPA) was measured with DCT. CDI was also performed. We measured haemodynamic parameters of the internal carotid artery (ICA), ophthalmic artery (OA), central retinal artery (CRA), and posterior ciliary arteries (PCA). Peak systolic (PSV), end-diastolic (EDV) velocities were measured, and resistance index (RI) and pulsatility index (PI) were calculated. Correlation with OPA showed indirect servitude in the RI of the ICA, RI and PI of the CRA, in the first group; and in the PSV and EDV of the ICA, in the RI and PI of the OA, EDV and RI of the CRA, and RI of the PCA, in the second group Increase of OPA was mostly followed by the increase of the parameters (PSV, EDV, RI, and PI) of the arteric retrobulbar vessels in the first group; in the second group, increase of OPA was in almost 50% of parameters followed by their decrease.

    A recent phase III trial showed that patients with advanced non-small cell lung cancer (NSCLC) whose tumors harbor specific EGFR mutations significantly benefit from first-line treatment with erlotinib compared to chemotherapy. This study sought to estimate the budget impact if coverage for EGFR testing and erlotinib as first-line therapy were provided in a hypothetical 500,000-member managed care plan. The budget impact model was developed from a US health plan perspective to evaluate administration of the EGFR test and treatment with erlotinib for EGFR-positive patients, compared to non-targeted treatment with chemotherapy. The eligible patient population was estimated from age-stratified SEER incidence data. Clinical data were derived from key randomized controlled trials. Costs related to drug, administration, and adverse events were included. Sensitivity analyses were conducted to assess uncertainty. In a plan of 500,000 members, it was estimated there would be 91 newly diagnosed advanced NSCLC patients annually; 11 are expected to be EGFR-positive. Based on the testing and treatment assumptions, it was estimated that 3 patients in Scenario 1 and 6 patients in Scenario 2 receive erlotinib. Overall health plan expenditures would increase by $0.013 per member per month (PMPM). This increase is largely attributable to erlotinib drug costs, in part due to lengthened progression-free survival and treatment periods experienced in erlotinib-treated patients. EGFR testing contributes slightly, whereas adverse event costs mitigate the budget impact. The budget impact did not exceed $0.019 PMPM in sensitivity analyses. Coverage for targeted first-line erlotinib therapy in NSCLC likely results in a small budget impact for US health plans. The estimated impact may vary by plan, or if second-line or maintenance therapy, dose changes/interruptions, or impact on patients' quality-of-life were included.

    Purpose: The purpose of this article was to share midterm results of percutaneous cholecystostomy (PC) as a first-line therapy in chronic hemodialysis patients with acute cholecystitis. Methods: Fourteen chronic hemodialysis patients with acute cholecystitis underwent PC between March 2007 and May 2009 at our institute. On preoperative assessment, the patients were classified into the ASA score by the anesthesiology team. All patients were class IV because of severe underlying comorbidities. The patients were referred to interventional radiology unit for PC by consensus of the multidisciplinary team. Results: The PC was technically successful in all the patients without minor or majormore » complications related to the procedure. Clinical symptoms in three patients who presented with sepsis and multiorgan failure did not resolve after PC, and these patients died following urgent surgery, including open cholecystectomy and common bile duct exploration. A new cholecystitis attack was detected in one patient in the acalculous group at the sixth month of the follow-up period. The mean catheterization time was 31.7 (range, 28-41) days. The mean follow-up time was 13.3 (range 4-21) months. Conclusions: The PC may come into consideration as a first-line treatment modality in the management of acute cholecystitis in poor surgical candidate chronic hemodialysis patients. This is the first report focusing on the midterm results of PC as a first-line therapy in hemodialysis patients with acute cholecystitis who could be operated on.« less

    To evaluate the effectiveness of zonisamide (ZNS) as monotherapy in children with newly diagnosed epilepsy. This randomized, multicenter trial included a 2-4-week titration and a 24-week maintenance phase after randomization to low-(3-4 mg/kg/day) or high-(6-8 mg/kg/day) dose groups as target maintenance dosages. The primary outcome measure was the seizure-free rate over 6 months, while a secondary measure was the change in cognition and behavior from screening to the end of the maintenance phase. Out of 125 patients enrolled, 90 (49 low-dose and 41 high-dose) completed the study. Forty-one patients (63.1%) in the low-dose group and 34(57.6%) in the high-dose group achieved 6 months' freedom from seizures (p=0.66). After treatment, the picture arrangement subtest improved in the low-dose group (p=0.047) while the vocabulary subtest worsened in the high-dose group (p=0.020). Comparing between the two groups, the vocabulary subtest in the high-dose group was significantly worse than that in the low-dose group (p=0.002). Social competence, somatic complaints, depression/anxiety and delinquent and aggressive behavior in the low-dose group were significantly improved (p<0.05). Moreover, total social competence, somatic complaints, delinquent behavior, externalizing, and total behavior problems were significantly more improved in the low-dose group than the high-dose group (p<0.05). ZNS is an effective monotherapy for newly diagnosed childhood epilepsy. Lower doses of ZNS have a similar efficacy and more beneficial neurocognitive effects compared to higher doses. When prescribing higher doses of ZNS, one must be aware of the possible manifestation of problems associated with language development, such as those affecting vocabulary acquisition.

    Current clinical practice guidelines sometimes still recommend stopping aspirin five to seven days before knee arthroplasty surgery. Literature regarding multimodal blood management and continuation of anti-platelet therapy in this type of surgery is scant. The study hypothesis was that knee arthroplasty under low-dose aspirin mono-therapy continuation does not cause more total blood loss than knee arthroplasty performed without aspirin. Blood loss would be measured by haemoglobin (Hb) and haematocrit (HTC) levels drop at day 2 or day 4 for patients who benefit from multimodal bleeding control measures. A database of all patients undergoing knee arthroplasty between 2006 and 2014 was analysed. Demographic, surgical and complete blood workup data were collected. A retrospective comparison study analysed both groups in terms of blood loss, by mean calculated blood loss as haemoglobin or haematocrit drop between the preoperative Nadir value and the postoperative day 2 and 4 value. A group of 198 (44 UKA and 154 TKA) patients underwent surgery without interrupting their aspirin therapy for cardiovascular prevention. Mean (SD) age was 71 (8) and the mean (SD) BMI was 29 (5.5) kg/m 2 . The control group consisted of 403 (102 UKA and 301 TKA) patients who were not under aspirin, or any other anti-platelet agent. Mean (SD) age was 65 (10) (p < 0.05) and the mean (SD) BMI was 29 (5.0) kg/m 2 (n.s.). All patients in the control group were randomly selected. There were no differences in terms of visible (early) or hidden (late) blood loss as measured by Hb drop in between both groups. There is no difference in transfusion rates. Modern multimodal blood management provides sufficient blood loss prevention during and after knee arthroplasty to allow physicians to continue low-dose aspirin mono-therapy for cardiovascular prevention.

    We produce synthetic spectra and observations for metal-free stellar populations and high-mass X-ray binaries in the Renaissance Simulations at a redshift of 15. We extend our methodology from the first paper in the series by modelling the production and extinction of emission lines throughout a dusty and metal-enriched interstellar and circum-galactic media extracted from the simulation, using a Monte Carlo calculation. To capture the impact of high-energy photons, we include all frequencies from hard X-ray to far-infrared with enough frequency resolution to discern line emission and absorption profiles. The most common lines in our sample in order of their rate of occurrence are Ly α, the C IV λλ1548, 1551 doublet, H α, and the Ca II λλλ8498, 8542, 8662 triplet. The best scenario for a direct observation of a metal-free stellar population is a merger between two Population III Galaxies. In mergers between metal-enriched and metal-free stellar populations, some characteristics may be inferred indirectly. Single Population III galaxies are too dim to be observed photometrically at z = 15. Ly α emission is discernible by JWST as an increase in J200w - J277w colour off the intrinsic stellar tracks. Observations of metal-free stars will be difficult, though not impossible, with the next generation of space telescopes.

    Background. Human immunodeficiency virus (HIV)-1 drug resistance mutations (DRMs) often accompany treatment failure. Although subtype differences are widely studied, DRM comparisons between subtypes either focus on specific geographic regions or include populations with heterogeneous treatments. Methods. We characterized DRM patterns following first-line failure and their impact on future treatment in a global, multi-subtype reverse-transcriptase sequence dataset. We developed a hierarchical modeling approach to address the high-dimensional challenge of modeling and comparing frequencies of multiple DRMs in varying first-line regimens, durations, and subtypes. Drug resistance mutation co-occurrence was characterized using a novel application of a statistical network model. Results. In 1425 sequences, 202 subtype B, 696 C, 44 G, 351 circulating recombinant forms (CRF)01_AE, 58 CRF02_AG, and 74 from other subtypes mutation frequencies were higher in subtypes C and CRF01_AE compared with B overall. Mutation frequency increased by 9%–20% at reverse transcriptase positions 41, 67, 70, 184, 215, and 219 in subtype C and CRF01_AE vs B. Subtype C and CRF01_AE exhibited higher predicted cross-resistance (+12%–18%) to future therapy options compared with subtype B. Topologies of subtype mutation networks were mostly similar. Conclusions. We find clear differences in DRM outcomes following first-line failure, suggesting subtype-specific ecological or biological factors that determine DRM patterns. PMID:27419147

    Objective According to a recent randomized, double-blind clinical trial comparing the combination of voriconazole and anidulafungin (VOR+ANI) with VOR monotherapy for invasive aspergillosis (IA) in patients with hematologic disease or with hematopoietic stem cell transplant, mortality was lower after 6 weeks with VOR+ANI than with VOR monotherapy in a post hoc analysis of patients with galactomannan-based IA. The objective of this study was to compare the cost-effectiveness of VOR+ANI with VOR, from the perspective of hospitals in the Spanish National Health System. Methods An economic model with deterministic and probabilistic analyses was used to determine costs per life-year gained (LYG) for VOR+ANI versus VOR in patients with galactomannan-based IA. Mortality, adverse event rates, and life expectancy were obtained from clinical trial data. The costs (in 2015 euros [€]) of the drugs and the adverse event-related costs were obtained from Spanish sources. A Tornado plot and a Monte Carlo simulation (1,000 iterations) were used to assess uncertainty of all model variables. Results According to the deterministic analysis, for each patient treated with VOR+ANI compared with VOR monotherapy, there would be a total of 0.348 LYG (2.529 vs 2.181 years, respectively) at an incremental cost of €5,493 (€17,902 vs €12,409, respectively). Consequently, the additional cost per LYG with VOR+ANI compared with VOR would be €15,785. Deterministic sensitivity analyses confirmed the robustness of these findings. In the probabilistic analysis, the cost per LYG with VOR+ANI was €15,774 (95% confidence interval: €15,763–16,692). The probability of VOR+ANI being cost-effective compared with VOR was estimated at 82.5% and 91.9%, based on local cost-effectiveness thresholds of €30,000 and €45,000, respectively. Conclusion According to the present economic study, combination therapy with VOR+ANI is cost-effective as primary therapy of IA in galactomannan

    Widespread use of antibiotics has resulted in increased rates of antibiotic resistance and decreased rates of Helicobacter pylori (H. pylori) eradication, leading to a search for newer therapeutic options. This study aimed to examine the efficacy, tolerability, and patient compliance of a first-line bismuth-containing 5-day concomitant quintuple therapy. This prospective study included 144 eradication treatment naïve H. pylori positive patients with dyspeptic complaints. Patients received the following concomitant quintuple therapy for 5 days: bismuth subcitrate 300 mg q.i.d, omeprazole 20 mg b.i.d, clarithromycin 500 mg b.i.d., amoxicillin 1 g b.i.d., and metronidazole 500 mg t.i.d. Eradication was assessed with H. pylori stool antigen test or urea-breath test 6 weeks after the completion of therapy. Treatment compliance rate in this study was 97.2%. Intention to treat and per-protocol eradication rates were 134/144 (93.1%, 95% CI, 88.9-97.2) and 134/140 (95.7%, 95% CI, 92.2-98.6), respectively. Side effect was reported by 8.5% of the patients that attended follow-up visits, including epigastric pain (2.8%), nausea/vomiting (2.1%), diarrhea (1.4%), taste disturbance (1.4%), and fatigue (0.7%). Bismuth-containing, short course, quintuple concomitant therapy appears to be an effective and safe therapeutic option for the first-line H. pylori eradication, particularly in populations with high resistance. © 2015 John Wiley & Sons Ltd.

    Endocrine therapy continues to be the optimal systemic treatment for metastatic ER(+)HER2(-) breast cancer. The CDK4/6 inhibitor palbociclib combined with letrozole has recently been shown to significantly improve progression-free survival. Here we examined the cost-effectiveness of this regimen for the Swiss healthcare system. A Markov cohort simulation based on the PALOMA-1 trial (Finn et al. in Lancet Oncol 16:25-35, 2015) was used as the clinical course. Input parameters were based on summary trial data. Costs were assessed from the Swiss healthcare system perspective. Adding palbociclib to letrozole (PALLET) compared to letrozole monotherapy was estimated to cost an additional CHF342,440 and gain 1.14 quality-adjusted life years, resulting in an incremental cost-effectiveness ratio (ICER) of CHF301,227/QALY gained. In univariate sensitivity analyses, no tested variation in key parameters resulted in an ICER below a willingness-to-pay threshold of CHF100,000/QALY. PALLET had a 0 % probability of being cost-effective in probabilistic sensitivity analyses. Lowering PALLET's price by 75 % resulted in an ICER of CHF73,995/QALY and a 73 % probability of being cost-effective. At current prices, PALLET would cost the Swiss healthcare system an additional CHF155 million/year. Palbociclib plus letrozole cannot be considered cost-effective for the first-line treatment of patients with metastatic breast cancer in the Swiss healthcare system.

    Primary immune thrombocytopenia is a severe bleeding disorder. About 50-85% of patients achieve initial remission from first-line therapies, but optimal second-line treatment remains a challenge. All-trans retinoic acid (ATRA) has an immunomodulatory effect on haemopoiesis, making it a possible treatment option. We aimed to evaluate the efficacy and safety of ATRA plus danazol versus danazol in non-splenectomised patients with corticosteroid-resistant or relapsed primary immune thrombocytopenia. We did a multicentre, randomised, open-label, phase 2 study of adult patients (≥18 years) with primary immune thrombocytopenia from five different tertiary medical centres in China. Those eligible were non-splenectomised, resistant to corticosteroid treatment or relapsed, and had a platelet count less than 30 × 10 9 per L. Masked statisticians used simple randomisation to assign patients (1:1) to receive oral ATRA (10 mg twice daily) plus oral danazol (200 mg twice daily) or oral danazol monotherapy (200 mg twice daily) for 16 weeks. Neither clinicians nor patients were masked to group assignments. All patients were assessed every week during the first 8 weeks of treatment, and at 2-week intervals thereafter. The primary endpoint was 12-month sustained response defined as platelet count of 30 × 10 9 per L or more and at least a doubling of baseline platelet count (partial response), or a platelet count of 100 × 10 9 per L or more (complete response) and the absence of bleeding without rescue medication at the 12-month follow-up. All randomly allocated patients, except for those who withdrew consent, were included in the modified intention-to-treat population and efficacy assessment, and all patients who received at least one dose of the study agents were included in the safety analysis. Study enrolment was stopped early because the trial results crossed the interim analysis efficacy boundary for sustained response. This trial is registered with Clinical

    In this study we report the prevalence of antiretroviral drug resistant HIV-1 genotypes of virus isolated from Djiboutian patients who failed first-line antiretroviral therapy (ART) and from ART naïve patients. A total of 35 blood samples from 16 patients who showed first-line ART failure (>1000 viral genome copies/ml) and 19 ART-naïve patients were collected in Djibouti from October 2009 to December 2009. Both the protease (PR) and reverse transcriptase (RT) genes were amplified and sequenced using National Agency for AIDS Research (ANRS) protocols. The Stanford HIV database algorithm was used for interpretation of resistance data and genotyping. Among the 16 patients with first-line ART failure, nine (56.2%) showed reverse transcriptase inhibitor-resistant HIV-1 strains: two (12.5%) were resistant to nucleoside (NRTI), one (6.25%) to non-nucleoside (NNRTI) reverse transcriptase inhibitors, and six (37.5%) to both. Analysis of the DNA sequencing data indicated that the most common mutations conferring drug resistance were M184V (38%) for NRTI and K103N (25%) for NNRTI. Only NRTI primary mutations K101Q, K103N and the PI minor mutation L10V were found in ART naïve individuals. No protease inhibitor resistant strains were detected. In our study, we found no detectable resistance in ∼ 44% of all patients who experienced therapeutic failure which was explained by low compliance, co-infection with tuberculosis and malnutrition. Genotyping revealed that 65.7% of samples were infected with subtype C, 20% with CRF02_AG, 8.5% with B, 2.9% with CRF02_AG/C and 2.9% with K/C. The results of this first study about drug resistance mutations in first-line ART failures show the importance of performing drug resistance mutation test which guides the choice of a second-line regimen. This will improve the management of HIV-infected Djiboutian patients. The virtual slide(s) for this article can be found here: http://www.diagnosticpathology.diagnomx.eu/vs/2051206212753973.

    Objective To assess whether combination treatment with lithium and divalproex is more effective than lithium monotherapy in prolonging the time to mood episode recurrence in patients with rapid-cycling bipolar disorder (RCBD) and comorbid substance abuse and/or dependence. Method A 6-month, double-blind, parallel group comparison was carried out in recently manic/hypomanic/mixed patients who had demonstrated a persistent bimodal response to combined treatment with lithium and divalproex. Subjects were randomly assigned to remain on combination treatment or to discontinue divalproex and remain on lithium monotherapy. Results Of 149 patients enrolled into the open-label acute stabilization phase, 79% discontinued prematurely (poor adherence: 42%; nonresponse: 25%; intolerable side effects: 10%). Of 31 patients (21%) randomly assigned to double-blind maintenance treatment, 55% relapsed (24% into depression and 76% into a manic/hypomanic/mixed episode), 26% completed the study, and 19% were poorly adherent or exited prematurely. The median time to recurrence of a new mood episode was 15.9 weeks for patients receiving lithium monotherapy and 17.8 weeks for patients receiving the combination of lithium and divalproex (p=NS). The rate of relapse into a mood episode for those receiving lithium monotherapy or the combination of lithium and divalproex was 56% and 53%, respectively. The rate of depressive relapse in both arms was 13%, while the rate of relapse into a manic, hypomanic, or mixed episode was 44% for lithium monotherapy and 40% for the combination of lithium and divalproex. Conclusion A small subgroup of patients in this study stabilized after six months of treatment with lithium plus divalproex. Of those who did, the addition of divalproex to lithium conferred no additional prophylactic benefit over lithium alone. Although depression is regarded as the hallmark of RCBD in general, these data suggest that recurrent episodes of mania tend to be more common in

    To evaluate the ability of tocilizumab (a humanised anti-IL-6 receptor antibody) monotherapy to inhibit progression of structural joint damage in patients with RA. In a multi-centre, x ray reader-blinded, randomised, controlled trial, 306 patients with active RA of <5 years' duration were allocated to receive either tocilizumab monotherapy at 8 mg/kg intravenously every 4 weeks or conventional disease-modifying antirheumatic drugs (DMARDs) for 52 weeks. Radiographs of hands and forefeet were scored by the van der Heijde modified Sharp method. Patients had a mean disease duration of 2.3 years and a disease activity score in 28 joints of 6.5 at baseline. Mean total modified Sharp score (TSS) was 29.4, which was very high despite the relatively short disease duration. At week 52, the tocilizumab group showed statistically significantly less radiographic change in TSS (mean 2.3; 95% CI 1.5 to 3.2) than the DMARD group (mean 6.1; 95% CI 4.2 to 8.0; p<0.01). Tocilizumab monotherapy also improved signs and symptoms. The overall incidences of AEs were 89% and 82% (serious AEs: 18% and 13%; serious infections: 7.6% and 4.1%) in the tocilizumab and DMARD groups, respectively. Tocilizumab monotherapy was generally well tolerated and provided radiographic benefit in patients with RA.

    The aim of the present study was to evaluate the feasibility and preliminary outcomes of high-dose-rate (HDR)-brachytherapy as a monotherapy in two fractions within 1 day for localized prostate cancer, including high-/very high-risk cases. Among the 68 patients treated with HDR monotherapy between July 2011 and December 2014, 65 had a minimal follow-up of 12 months without adjuvant androgen deprivation therapy and were enrolled in the present study [42/65 (64.6%) exhibited high-/very high-risk diseases]. HDR monotherapy was performed in two fractions with a minimal interval of 6 h and the prescribed dose was 13.5 Gy (×2). Adverse events (AEs) were assessed using Common Terminology Criteria for Adverse Events (version 4; http://ctep.cancer.gov/protocolDevelopment/electronic_applications/ctc.htm#ctc_40), and biochemical failure was assessed by the Phoenix definition. The median follow-up time was 30.1 months. The majority of patients had Grade 0-1 acute AEs. Four patients (6.2%) exhibited urinary retention, requiring a Foley catheter. Grade 3 acute AEs occurred at a frequency of 3.1% and hematuria at 1.5%. The majority of patients also exhibited Grade 0-1 chronic AEs. Grade 3 chronic AEs occurred at a frequency of 1.5% and urethral stricture at 1.5%, for which endoscopic treatment was indicated. Acute and chronic gastrointestinal AEs were uncommon, and no Grade 3 or above AEs developed. Biochemical failure occurred in 4 patients who all exhibited high-/very high-risk diseases. Kaplan-Meier estimated that 3 year biochemical failure-free survival was 91.6% overall and 88.0% in high-/very high-risk cases. The present two-fraction 1 day HDR monotherapy is feasible with minimal AEs and achieved acceptable biochemical control of localized prostate cancer, including high-/very high-risk cases, although long-term follow-up is required.

    The aim of this work is to compare the efficacy of pharmacologic agents for the treatment of major depressive disorder (MDD) and bipolar depression. MEDLINE/PubMed databases were searched for studies published in English between January 1980 and September 2014 by cross-referencing the search term placebo with each of the antidepressant agents identified and with bipolar. The search was supplemented by manual bibliography review. We selected double-blind, randomized, placebo-controlled trials of antidepressant monotherapies for the treatment of MDD and of oral drug monotherapies for the treatment of bipolar depression. 196 trials in MDD and 19 trials in bipolar depression were found eligible for inclusion in our analysis. Data were extracted by one of the authors and checked for accuracy by a second one. Data extracted included year of publication, number of patients randomized, probability of receiving placebo, duration of the trial, baseline symptom severity, dosing schedule, study completion rates, and clinical response rates. Response rates for drug versus placebo in trials of MDD and bipolar depression were 52.7% versus 37.5% and 54.7% versus 40.5%, respectively. The random-effects meta-analysis indicated that drug therapy was more effective than placebo in both MDD (risk ratio for response = 1.373; P < .001) and bipolar depression (risk ratio = 1.257; P < .001) trials. The meta-regression analysis suggested a statistically significant difference in the risk ratio of responding to drug versus placebo between MDD and bipolar depression trials in favor of MDD (P = .008). Although a statistically significantly greater treatment effect size was noted in MDD relative to bipolar depression studies, the absolute magnitude of the difference was numerically small. Therefore, the present study suggests no clinically significant differences in the overall short-term efficacy of pharmacologic monotherapies for MDD and bipolar depression. © Copyright 2016 Physicians

    Tenofovir disoproxil fumarate (TDF) and lopinavir/ritonavir (LPV/r) can cause renal impairment with this combination co-administered during second-line combination antiretroviral therapy (cART) potentially associated with greater risk of nephrotoxicity. As a result, the aim of this study is to assess effects of second-line cART on renal function. Retrospective longitudinal study in patients receiving cART. 71 patients received TDF, zidovudine or stavudine, each combined with 3TC/NVP or 3TC/EFV. Before second-line cART, 46.5% had abnormal kidney function. First-line cART had no relationship with calculated creatinine clearance (CrCl). During second-line cART, more males than females had abnormal renal function and more females experienced increases in CrCl. Calculated CrCl during second-line cART related strongly with CrCl during first-line cART. Time spent on cART had a weak relationship with CrCl. Patients on first-line cART for several years without renal impairment may experience new onset impairment during second line cART. Patients with pre-existing renal impairment just before switching to second-line cART may experience a further decline.

    Monotherapy with pegylated interferon-α (Peg-IFNα) or the nucleos(t)ide analogs (NA) currently approved for treating chronic hepatitis B (CHB) has limited efficacy. Studies on the combination of Peg-IFNα/NA have shown conflicting results. We investigated whether sequentially adding on Peg-IFNα to tenofovir enhances serological response rates. Treatment-naïve, hepatitis B envelope antigen (HBeAg)-positive CHB patients with moderately elevated alanine aminotransferase (ALT; 48-200 IU/mL) were started on tenofovir (300 mg/day) and enrolled at week 12 in a 1:1 ratio to either receive Peg-IFNα2b add-on (1.5 μg/kg/week) from week 12 to 36 (n = 53) or continue tenofovir monotherapy (n = 53). Both treatment arms received tenofovir consolidation therapy until week 72. The primary end-point was HBeAg loss at week 72. At week 72, the rate of HBeAg loss was higher in the Peg-IFNα2b add-on group (35.8%) compared to the tenofovir monotherapy group (17%) (P = 0.028; odds ratio, 2.73, 95% confidence interval, 1.09-6.79), and considerably higher in patients with a baseline hepatitis B virus (HBV)-DNA level >6 log IU/mL (32.6% vs 11.4%; P = 0.021). Rates of HBV-DNA loss (77.4% vs 71.7%; P = 0.51), ALT normalization (62.3% vs 52.8%; P = 0.32), and sustained virologic response (20.8% vs 11.3%; P = 0.18) at week 72 were comparable between the two groups. Significantly more patients in the add-on group had >3 log HBV-DNA reduction at week 36 (92.5% vs 66%; P = 0.001). Four patients treated with Peg-IFNα2b add-on achieved hepatitis B surface antigen (HBsAg) loss compared with one patient receiving tenofovir monotherapy. Decline of HBV-DNA of >2 log at week 4 led to higher HBeAg loss at week 72, independent of treatment arm. No patient had treatment-related adverse effects requiring treatment discontinuation. Twenty-four weeks of Peg-IFNα2b as an add-on sequential regimen to tenofovir is safe and resulted in greater loss of HBeAg and HBs

    BACKGROUND. Prognosis of patients with recurrent glioblastoma (GBM) remains dismal, their median overall survival (mOS) ranging from 7 to 10 months. Currently, bevacizumab (BEV), a monoclonal antibody against VEGF, has been widely used since it prolonged progression-free survival (PFS) accompanied with symptom relief in BEV trials. However, improvement of OS seems modest at most, and issues regarding short survival after BEV failure, invasive relapse, and difficulty in determining true progression remain unsolved. Here we examined the patterns of radiological BEV failure in relationship with survival of several post-treatment periods. METHODS. Twenty-five patients with primary GBM who were treated with BEV monotherapy at recurrence in Kyorin University hospital since August 2009 were included in this study. Mean age was 53 yo, 13 males/12 females, median KPS was 60 (30-100), and mOS from the initial surgery was 23.2 months. MRI patterns at BEV progression were determined using modified classification by Nowosielsky et al. (Neurology 2014) as follows: 1) T2-diffuse, 2) cT1-flare up, 3) Primary non-responders, 4) T2-circumscribed, and 5) Remote metastasis. RESULTS. mPFS and mOS of BEV monotherapy were 3.4 and 7.6 months, respectively, and post-BEV mOS was 4.7 months. Frequency and BEV-PFS/post-BEV OS were 1) 20%, 3.8/0.8 months; 2) 40%, 3.4/7.1 months, 3) 24%, 0.9/3.3 months, 4) 8%, 3.7/3.9 months, 5) 8%, 2.0/4.2 months. The cT1-flare up recurrent pattern was found most frequently with relatively better survivals, whereas the T2-diffuse recurrence included fatal brain stem invasion in two cases, resulting in poorer prognosis. CONCLUSIONS. BEV monotherapy showed limited survival benefit and the clinical course after BEV failure may differ by patterns of relapse. Although RANO criteria have been a standard method to determine progression, measurement of T2/FLAIR hyperintensity remains critically controversial.

    To evaluate the clinical experience with methotrexate as a first-line corticosteroid-sparing drug in patients with resistant ocular inflammation. We retrospectively studied 39 consecutive patients with uveitis (n = 36) or scleritis (n = 3) who were treated with methotrexate following inadequate control with corticosteroids lasting five years. Criteria for initiating treatment with methotrexate and defining outcome were strictly defined. The cohort included 21 females and 18 males, all Caucasians, with a mean age of 26.6 years (range: 3-73 years). Patients were followed up for 21.5 +/- 12.6 months. Treatment was discontinued due to side effects in 10 patients (26%). Of the remaining 29 patients, full or partial control of inflammation was achieved in 23 (79%). Response to treatment was observed after a mean of 2.4 +/- 0.8 months. Ten patients were fully controlled and discontinued methotrexate therapy after a mean of 20.9 +/- 9.2 months, with no recurrence of inflammation. Use of topical and systemic corticosteroids was markedly reduced in responsive patients. Methotrexate is recommended as a first-line adjunct to or replacement of systemic corticosteroids in the treatment of ocular inflammation.

    (1) To establish whether pre-treatment headache intensity in migraine or episodic tension-type headache (ETTH) predicts success or failure of treatment with aspirin; and (2) to reflect, accordingly, on the place of aspirin in the management of these disorders. Stepped care in migraine management uses symptomatic treatments as first-line, reserving triptans for those in whom this proves ineffective. Stratified care chooses between symptomatic therapy and triptans as first-line on an individual basis according to perceived illness severity. We questioned the 2 assumptions underpinning stratified care in migraine that greater illness severity: (1) reflects greater need; and (2) is a risk factor for failure of symptomatic treatment but not of triptans. With regard to the first assumption, we developed a rhetorical argument that need for treatment is underpinned by expectation of benefit, not by illness severity. To address the second, we reviewed individual patient data from 6 clinical trials of aspirin 1000 mg in migraine (N = 2079; 1165 moderate headache, 914 severe) and one of aspirin 500 and 1000 mg in ETTH (N = 325; 180 moderate, 145 severe), relating outcome to pre-treatment headache intensity. In migraine, for headache relief at 2 hours, a small (4.7%) and non-significant risk difference (RD) in therapeutic gain favored moderate pain; for pain freedom at 2 hours, therapeutic gains were almost identical (RD: -0.2%). In ETTH, for headache relief at 2 hours, RDs for both aspirin 500 mg (-4.2%) and aspirin 1000 mg (-9.7%) favored severe pain, although neither significantly; for pain freedom at 2 hours, RDs (-14.2 and -3.6) again favored severe pain. In neither migraine nor ETTH does pre-treatment headache intensity predict success or failure of aspirin. This is not an arguable basis for stratified care in migraine. In both disorders, aspirin is first-line treatment regardless of headache intensity. © 2011 American Headache Society.

    Background Distorted activity of the hypothalamic-pituitary-adrenocortical (HPA) system is one of the most robustly documented biological abnormalities in major depression. Lithium is central to the treatment of affective disorders, but little is known about its effects on the HPA system of depressed subjects. Objective To assess the effects of lithium monotherapy on the HPA system of patients with major depression by means of the combined DEX/CRH test. Method Thirty drug-naive outpatients with major depression (single episode or unipolar recurrent; SCID I- and II-confirmed) were treated with lithium monotherapy for four weeks. The DEX/CRH test was conducted directly before intake of the first lithium tablet and four weeks thereafter. Weekly ratings with the HDRS21 were used to determine response (≥50% symptom reduction) and remission (HDRS ≤7). Results Lithium levels within the therapeutic range were achieved rapidly. Tolerability was good; no patient terminated the treatment prematurely. Response and remission rates were 50% and 33% respectively. Compared to the DEX/CRH test before the start of the treatment, a considerable and significant increase in all CRH-stimulated ACTH and cortisol parameters could be detected in the second DEX/CRH test. When analysed with particular regard to responders and non-responders, that significant increase was only present in the responders. Conclusions We were able to demonstrate that lithium leads to a significant activation of the HPA system. This is possibly connected to stimulation of hypothalamic arginine vasoporessin (AVP), to direct intracellular effects of lithium on pituitary cells and to an induction of gene expression.

    We present an analysis of high-resolution spectroscopy of several bright T Tauri stars using the CRIRES spectrograph on the Very Large Telescope and NIRSPEC spectrograph on the Keck Telescope, revealing the first detections of emission from HCN and C2H2 in circumstellar disks at near-infrared wavelengths. Using advanced data reduction techniques, we achieve a dynamic range with respect to the disk continuum of ~500 at 3 μm, revealing multiple emission features of H2O, OH, HCN, and C2H2. We also present stringent upper limits for two other molecules thought to be abundant in the inner disk, CH4 and NH3. Line profiles for the different detected molecules are broad but centrally peaked in most cases, even for disks with previously determined inclinations of greater than 20°, suggesting that the emission has both a Keplerian and non-Keplerian component as observed previously for CO emission. We apply two different modeling strategies to constrain the molecular abundances and temperatures: we use a simplified single-temperature local thermal equilibrium (LTE) slab model with a Gaussian line profile to make line identifications and determine a best-fit temperature and initial abundance ratios, and we compare these values with constraints derived from a detailed disk radiative transfer model assuming LTE excitation but utilizing a realistic temperature and density structure. Abundance ratios from both sets of models are consistent with each other and consistent with expected values from theoretical chemical models, and analysis of the line shapes suggests that the molecular emission originates from within a narrow region in the inner disk (R < 1 AU). Based partially on observations collected at the European Southern Observatory Very Large Telescope under program ID 179.C-0151, program ID 283.C-5016, and program ID 082.C-0432 (P.I.: Pontopiddan).

    A new first-line antiretroviral therapy (ART) regimen containing dolutegravir is being rolled out in low-income and middle-income countries (LMICs). In studies from predominantly high-income settings, dolutegravir-based regimens had superior efficacy, tolerability, and durability compared with existing first-line regimens. However, several questions remain about the roll out of dolutegravir in LMICs, where most people with HIV are women of reproductive age, tuberculosis prevalence can be high, and access to viral load and HIV drug resistance testing is limited. Findings from cohort studies suggest that dolutegravir is safe when initiated in pregnancy, but more data are needed to determine the risk of adverse birth outcomes when dolutegravir-based regimens are initiated before conception. Increasing access to viral load testing to monitor the effectiveness of dolutegravir remains crucial, but the best strategy to manage patients with viraemia is unclear. Furthermore, evidence to support the effectiveness of dolutegravir when given with tuberculosis treatment is scarce, particularly in programmatic settings in LMICs. Lastly, whether nucleoside reverse transcriptase inhibitor resistance will affect the long-term efficacy of dolutegravir-based regimens in first-line, and potentially second-line, ART is unknown. Clinical trials, cohorts, and surveillance of HIV drug resistance will be necessary to answer these questions and to maximise the benefits of this new regimen. Copyright © 2018 Elsevier Ltd.

    The cost of chemotherapy has dramatically increased in advanced colorectal cancer patients, and the schedule of fluorouracil administration appears to be a determining factor. This retrospective study compared direct medical costs related to two different de Gramont schedules (standard vs. simplified) given in first-line chemotherapy with oxaliplatin or irinotecan. This cost-minimization analysis was performed from the French Health System perspective. Consecutive unselected patients treated in first-line therapy by LV5FU2 de Gramont with oxaliplatin (Folfox regimen) or with irinotecan (Folfiri regimen) were enrolled. Hospital and outpatient resources related to chemotherapy and adverse events were collected from 1999 to 2004 in 87 patients. Overall cost was reduced in the simplified regimen. The major factor which explained cost saving was the lower need for admissions for chemotherapy. Amount of cost saving depended on the method for assessing hospital stay. In patients treated by the Folfox regimen the per diem and DRG methods found cost savings of Euro 1,997 and Euro 5,982 according to studied schedules; in patients treated by Folfiri regimen cost savings of Euro 4,773 and Euro 7,274 were observed, respectively. In addition, travel costs were also reduced by simplified regimens. The robustness of our results was showed by one-way sensitivity analyses. These findings demonstrate that the simplified de Gramont schedule reduces costs of current first-line chemotherapy in advanced colorectal cancer. Interestingly, our study showed several differences in costs between two costing approaches of hospital stay: average per diem and DRG costs. These results suggested that standard regimen may be considered a profitable strategy from the hospital perspective. The opposition between health system perspective and hospital perspective is worth examining and may affect daily practices. In conclusion, our study shows that the simplified de Gramont schedule in combination with

    This study assessed disruption of first-line treatments initiated after the approval of the first CDK 4/6 inhibitor, palbociclib, among post-menopausal women with HR+/HER2- metastatic breast cancer (mBC) in the US. Post-menopausal women with HR+/HER2- mBC who initiated first-line endocrine therapy or chemotherapy (index therapy) between February 3, 2015 (palbociclib approval date) and February 29, 2016 (end of data) were identified from the Symphony Source Lx database. Patients were required to have continuous quarterly activity (defined as ≥1 pharmacy or medical claim) for 12 months prior to and 1 month after the initiation of the index therapy (index date). Treatment disruption was defined as a treatment gap of ≥60 days or adding an agent after the original therapy. Kaplan-Meier analyses were conducted to estimate treatment disruption rates during the 6 months following the index date. Patients without treatment disruption were censored at the end of continuous quarterly activity or end of data. A total of 8,160 and 2,153 eligible patients initiated endocrine therapy or chemotherapy as their first-line mBC treatment, with a median follow-up of 6.7 and 7.6 months, respectively. The three most prevalent metastatic sites were bone (28.1-42.2%), liver (8.8-17.3%), and lung (8.6-9.5%). Overall, 37.7% (n = 3,074) of patients receiving endocrine therapy and 86.1% (n = 1,852) of patients receiving chemotherapy encountered treatment disruption at 6 months (log-rank test p < .05). Treatment disruption rates of first-line therapies were sub-optimal among post-menopausal women with HR+/HER2- mBC, primarily driven by chemotherapy users. New therapies or interventions are needed to reduce treatment disruption in this patient population.

    Background A targeted agent combined with chemotherapy is the standard treatment in patients with metastatic colorectal cancer (mCRC). The present phase III study was conducted to compare two doses of bevacizumab combined with irinotecan, 5-fluorouracil/leucovorin (FOLFIRI) in the second-line setting after first-line therapy with bevacizumab plus oxaliplatin-based therapy. Patients and methods Patients were randomly assigned to receive FOLFIRI plus bevacizumab 5 or 10 mg/kg in 2-week cycles until disease progression. The primary end point was progression-free survival (PFS), and secondary end points included overall survival (OS), time to treatment failure (TTF), and safety. Results Three hundred and eighty-seven patients were randomized between September 2009 and January 2012 from 100 institutions in Japan. Baseline patient characteristics were well balanced between the two groups. Efficacy was evaluated in 369 patients (5 mg/kg, n = 181 and 10 mg/kg, n = 188). Safety was evaluated in 365 patients (5 mg/kg, n = 180 and 10 mg/kg, n = 185). The median PFS was 6.1 versus 6.4 months (hazard ratio, 0.95; 95% confidence interval [CI] 0.75–1.21; P = 0.676), and median TTF was 5.2 versus 5.2 months (hazard ratio, 1.01; 95% CI 0.81–1.25; P = 0.967), respectively, for the bevacizumab 5 and 10 mg/kg groups. Follow-up of OS is currently ongoing. Adverse events, including hypertension and hemorrhage, occurred at similar rates in both groups. Conclusion Bevacizumab 10 mg/kg plus FOLFIRI as the second-line treatment did not prolong PFS compared with bevacizumab 5 mg/kg plus FOLFIRI in patients with mCRC. If bevacizumab is continued after first-line therapy in mCRC, a dose of 5 mg/kg is appropriate for use as second-line treatment. Clinical trial identifier UMIN000002557. PMID:25908603

    Follicular lymphoma (FL) is the second most common type of lymphoid cancer in Western Europe. The aim of this study was to evaluate the cost utility of rituximab-bendamustine treatment compared with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone) treatment as a first-line therapy for patients with advanced FL in Spain. A Markov model was developed to estimate the cost effectiveness of rituximab-bendamustine compared with R-CHOP as first-line treatment for patients with advanced FL in the Spanish National Health System (NHS). Transitions between health states (progression-free, including induction and maintenance; first relapse; second relapse; and death) were allowed for the patient cohort in 4-week-long cycles. Clinical data for the extrapolation of progression-free survival curves were obtained from randomized trials. Mortality rates and utilities were obtained from the literature. Outcomes were measured as quality-adjusted life-years (QALYs). The total costs (€, 2013) included drug costs (ex-factory prices with mandatory deductions), disease management costs and adverse event-associated costs. Costs and outcomes were discounted at a 3 % annual rate. Probabilistic sensitivity analysis was performed using 10,000 Monte Carlo simulations to assess the model robustness. Treatment and administration costs during the induction phase were higher for rituximab-bendamustine (€17,671) than for R-CHOP (€11,850). At the end of the 25-year period, the rituximab-bendamustine first-line strategy had a total cost of €68,357 compared with €69,528 for R-CHOP. Health benefits were higher for rituximab-bendamustine treatment (10.31 QALYs) than for R-CHOP treatment (9.82 QALYs). In the probabilistic analysis, rituximab-bendamustine was the dominant strategy over treatment with R-CHOP in 53.4 % of the simulations. First-line therapy with rituximab-bendamustine in FL patients was the dominant strategy over treatment with R-CHOP; it showed cost

    OBJECTIVE—Rapamycin is an immunosuppressive drug currently used to prevent graft rejection in humans, which is considered permissive for tolerance induction. Rapamycin allows expansion of both murine and human naturally occurring CD4+CD25+FOXP3+ T regulatory cells (nTregs), which are pivotal for the induction and maintenance of peripheral tolerance. Preclinical murine models have shown that rapamycin enhances nTreg proliferation and regulatory function also in vivo. Objective of this study was to assess whether rapamycin has in vivo effects on human nTregs. RESEARCH DESIGN AND METHODS—nTreg numbers and function were examined in a unique set of patients with type 1 diabetes who underwent rapamycin monotherapy before islet transplantation. RESULTS—We found that rapamycin monotherapy did not alter the frequency and functional features, namely proliferation and cytokine production, of circulating nTregs. However, nTregs isolated from type 1 diabetic patients under rapamycin treatment had an increased capability to suppress proliferation of CD4+CD25− effector T-cells compared with that before treatment. CONCLUSIONS—These findings demonstrate that rapamycin directly affects human nTreg function in vivo, which consists of refitting their suppressive activity, whereas it does not directly change effector T-cell function.

    Abstract The treatment efficacy of advanced breast cancer is still not promising. This study aimed to compare the efficacy and safety of docetaxel/S-1 (DS1) versus docetaxel/capecitabine (DX) as the first-line treatment for advanced breast cancer. From June 2008 to June 2013, 22 patients with advanced breast cancer were treated with the DS1 regimen. Another 26 age- and disease status-matched patients treated with the DX regimen served as controls. The 2 groups were compared in terms of time to progression (TTP), objective response rate, disease control rate, clinical benefit rate, and safety profiles. Median TTP did not differ significantly between the DS1 group and the DX group (9.04 vs 10.94 months, P = 0.473). There were no significant differences in objective response rate, disease control rate, and clinical benefit rate between the 2 groups. Both the DS1 and the DX regimens showed good tolerability. The 2 regimens showed no significant difference in adverse events except degree III hand-foot syndrome (DS1 0 vs DX 23.1%, P = 0.025). For the first-line treatment of advanced breast cancer, the DS1 and the DX regimens showed similar efficacy and safety. The DS1 regimen had less severe hand-foot syndrome than the DX regimen.

    Objectives Zidovudine (AZT) is recommended for first-line antiretroviral therapy (ART) in resource limited settings. AZT may, however, lead to anemia and impaired immunological response. We compared CD4 counts over 5 years between patients starting ART with and without AZT in Southern Africa. Design Cohort study Methods Patients aged ≥16 years who started first-line ART in South Africa, Botswana, Zambia or Lesotho were included. We used linear mixed-effect models to compare CD4 cell count trajectories between patients on AZT-containing regimens and patients on other regimens, censoring follow-up at first treatment change. Impaired immunological recovery, defined as a CD4 count below 100 cells/μl at 1 year, was assessed in logistic regression. Analyses were adjusted for baseline CD4 count and haemoglobin level, age, gender, type of regimen, viral load monitoring and calendar year. Results 72,597 patients starting ART, including 19,758 (27.2%) on AZT, were analysed. Patients on AZT had higher CD4 cell counts (150 vs.128 cells/μl) and haemoglobin level (12.0 vs. 11.0 g/dl) at baseline, and were less likely to be female than those on other regimens. Adjusted differences in CD4 counts between regimens containing and not containing AZT were −16 cells/μl (95% CI −18 to −14) at 1 year and −56 cells/μl (95% CI −59 to −52) at 5 years. Impaired immunological recovery was more likely with AZT compared to other regimens (odds ratio 1.40, 95% CI 1.22–1.61). Conclusions In Southern Africa AZT is associated with inferior immunological recovery compared to other backbones. Replacing AZT with another NRTI could avoid unnecessary switches to second-line ART.

    In October of 2010, Serbian Association for Psycho-Oncology, in collaboration with the Ministry of Health of Serbia and the National Health Insurance has launched the first national telephone line for free psychological counseling and support for oncology patients and their families. The aim of this study was to present results of the first national telephone helpline for psychological support for oncological patients and their families. METHODS The telephone line for the psychological help and support was available from 10 a.m. to 10 p.m., seven days a week and on holidays. A total of 12 previously educated psychologists were involved, with two on duty in the mornings and two in the afternoons.The basic work principles of the Line were anonymity for users (if they wished), free of charge service available to patients from all of Serbia, careful listening, emphatic reflection on anything communicated by users and adequate counselling. Since the beginning of the project (October 2010 up to April 2011) we received a total of 2,748 calls from across Serbia. Almost half of these calls were repeated calls, as patients asked for continuous psychological counselling. Larger percent (63.9%) of women called, when compared to men (35.4%) who used the Line. Most (52.4%) conversations were categorized as "psychological support and counseling," and as continual psychological counseling work (21.1%). The large number of calls suggests that this kind of public, free service for psychosocial and psychological support to cancer patients is necessary in Serbia.

    Nilotinib and dasatinib are now being considered as alternative treatments to imatinib as a first-line treatment of chronic myeloid leukaemia (CML). This technology assessment reviews the available evidence for the clinical effectiveness and cost-effectiveness of dasatinib, nilotinib and standard-dose imatinib for the first-line treatment of Philadelphia chromosome-positive CML. Databases [including MEDLINE (Ovid), EMBASE, Current Controlled Trials, ClinicalTrials.gov, the US Food and Drug Administration website and the European Medicines Agency website] were searched from search end date of the last technology appraisal report on this topic in October 2002 to September 2011. A systematic review of clinical effectiveness and cost-effectiveness studies; a review of surrogate relationships with survival; a review and critique of manufacturer submissions; and a model-based economic analysis. Two clinical trials (dasatinib vs imatinib and nilotinib vs imatinib) were included in the effectiveness review. Survival was not significantly different for dasatinib or nilotinib compared with imatinib with the 24-month follow-up data available. The rates of complete cytogenetic response (CCyR) and major molecular response (MMR) were higher for patients receiving dasatinib than for those with imatinib for 12 months' follow-up (CCyR 83% vs 72%, p < 0.001; MMR 46% vs 28%, p < 0.0001). The rates of CCyR and MMR were higher for patients receiving nilotinib than for those receiving imatinib for 12 months' follow-up (CCyR 80% vs 65%, p < 0.001; MMR 44% vs 22%, p < 0.0001). An indirect comparison analysis showed no difference between dasatinib and nilotinib for CCyR or MMR rates for 12 months' follow-up (CCyR, odds ratio 1.09, 95% CI 0.61 to 1.92; MMR, odds ratio 1.28, 95% CI 0.77 to 2.16). There is observational association evidence from imatinib studies supporting the use of CCyR and MMR at 12 months as surrogates for overall all-cause survival and progression-free survival in

    Aim of the study was to assess effect of monotherapy with nebivolol, bisoprolol, carvedilol for 2 months on sexual function in men with arterial hypertension (AH). Men with 1-2 degree of AH (n=75, age 35-55 years, mean age 48+/-3,5 years) received monotherapy with these drugs for 2 months. Registration of parameters of heart rate variability (HRV), Dopplerography of penile arteries, and the Vasilchenko questionnaire were implemented at the end of 4 months of placebo period and after 2 months of therapy with a study drug. Therapy with bisoprolol, carvedilol, and nebivolol was associated with significant elevation of parasympathetic part of vegetative nervous system tone, improvement of systolic blood flow in cavernous and dorsal arteries. Analysis of data obtained by Vasilchenko questionnaire demonstrated improvement of psychic and erectile components of sexual function. Thus bisoprolol, carvedilol, and nebivolol did not worsen sexual function of men with AH, improved spectral parameters of HRV and vascular blood flow in arteries of cavernous bodies.

    The response rate among 58 patients with cancer and candidemia or deep-seated candidiasis treated with micafungin monotherapy was 81%. Intensive care unit (ICU) stay, concomitant nonfungal infections, and acute kidney injury were significantly associated with the 30-day crude mortality rate. Severe neutropenia was an independent predictor of micafungin failure. The efficacy and safety of micafungin in cancer patients with invasive candidiasis were comparable to those reported for patients without malignancy and for cancer patients treated with caspofungin.

    We studied the relationship between intermediate criteria and overall survival (OS) in metastatic colorectal cancer (mCRC) patients who received first-line chemotherapy with bevacizumab. We assessed OS, progression-free survival (PFS), duration of disease control (DDC), the sum of the periods in which the disease did not progress, and the time to failure of strategy (TFS), which was defined as the entire period before the introduction of a second-line treatment. Linear correlation and regression models were used, and Prentice criteria were investigated. With a median follow-up of 57.6 months for 216 patients, the median OS was 24.5 months (95% confidence interval [CI], 21.3-29.7). The median PFS, DDC, and TFS were 8.9 (95% CI, 8.4-9.7), 11.0 (95% CI, 9.8-12.4), and 11.1 (95% CI, 10.0-13.0) months, respectively. The correlations between OS and DDC (Pearson coefficient, 0.79 [95% CI, 0.73-0.83], determination coefficient, 0.62) and OS and TFS (Pearson coefficient, 0.79 [95% CI, 0.73-0.84], determination coefficient, 0.63) were satisfactory. Linear regression analysis showed a significant association between OS and DDC, and between OS and TFS. Prentice criteria were verified for TFS as well as DDC. DDC and TFS correlated with OS and are relevant as intermediate criteria in the setting of patients with mCRC treated with a first-line bevacizumab-based regimen. Copyright © 2017 Elsevier Inc.

    Hepatic encephalopathy (HE) is a neuropsychiatric syndrome that occurs in up to 30% of patients with cirrhosis. HE may be a consequence of pure liver failure, as in patients with fulminant hepatitis, or of the combination of liver failure and portal-systemic shunting, as in patients with liver cirrhosis. Episodes of HE are usually related to precipitating events, such as infections or gastrointestinal bleeding; a minority of cirrhotic patients experienced a chronic HE, refractory to standard medical treatment. The prevention of HE recurrence, after the first episode of HE, could be obtained by the administration of prophylactic therapy with lactulose, rifaximin or a combination of both. The aim of this review is to clarify some key points in the management of cirrhotic patients with HE, not responsive to first line treatment. Recent studies investigated the role of fecal microbiota transplantation in the treatment of HE with promising results, but further investigations are needed. In a cirrhotic patient with acute cognitive impairment, the correct diagnosis of HE, after excluding other causes of neurological diseases, is mandatory for the correct management of the precipitating factors and for the treatment. In patients not responsive to standard treatment, the probable precipitating factors have not been correctly identified, multiple precipitating events are coexisting or a new precipitating event is superimposed. In some patients with recurrent HE, characterized by persistent alterations in neurological symptoms, without specific precipitants events, the presence of spontaneous or iatrogenic shunts should be investigated.

    To estimate the cost-effectiveness of tocilizumab (TCZ) monotherapy (Mono) versus adalimumab (ADA) Mono from the US payer perspective in patients with rheumatoid arthritis for whom methotrexate is inappropriate. We compared TCZ Mono (8 mg/kg monthly) with ADA Mono (40 mg every other week), using efficacy results from a head-to-head study, ADalimumab ACTemrA (ADACTA). We calculated the incremental cost per responder (achievement of American College of Rheumatology [ACR] 20% improvement criteria, ACR 50% improvement criteria, ACR 70% improvement criteria, or low disease activity score) for TCZ versus ADA at 6 months. A patient-level simulation was used to estimate the lifetime incremental cost per quality-adjusted life-year (QALY) of initiating treatment with TCZ Mono versus ADA Mono. Both drugs are followed by an etanercept-certolizumab-palliative care sequence. Nonresponders discontinue at 6 months; responders experience a constant probability of discontinuation. Discontinuers move to the next treatment. ACR responses produce changes in the Health Assessment Questionnaire (HAQ) score. We mapped the HAQ score to utility to estimate QALYs. Costs include those related to hospitalization and those related to treatment (drug acquisition, administration, and monitoring). Probabilistic and one-way sensitivity analyses were conducted, along with several scenario analyses. Compared with ADA, TCZ was more effective, with an estimated 6-month incremental cost ranging from $6,570 per additional low disease activity score achiever to $14,265 per additional ACR 70% improvement criteria responder. The lifetime incremental cost-effectiveness ratio was $36,944/QALY. TCZ Mono is projected to be cost-effective compared with ADA Mono in patients with severe rheumatoid arthritis for whom methotrexate is not appropriate, from a US payer perspective. Copyright © 2015.

    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.

    The paper is to systematically evaluate the effect and safety of Shenqi Fuzheng injection (SFI) combined with first-line chemotherapy for non-small cell lung cancer (NSCLC). Randomized controlled trials (RCTs) on Shenqi Fuzheng injection (SFI) combined with first-line chemotherapy (experiment group) and chemotherapy alone group ( control group) were electronically retrieved from Medline, EMbase, Clinical Trials, Cochrane Library, CBM, CNKI, VIP, and Wanfang Data base. All trials were assessed for quality according to the Cochrane Reviewer's Handbook for Systematic Reviews of Intervention and then Meta-analysis was performed withRevMan5. 2 Software. A total of 43 RCTs (3433 patients) were included after screening and selecting. Results of Meta-analysis showed that: Objective remission rate (ORR): ORR of experimental group was about 20% higher than that of control group [RR = 1.23, 95% CI (1.11,1.35), P < 0.0001]. Disease control rate (DCR):DCR of SFI combined with first-line chemotherapy was 11% higher than that of first-line chemotherapy alone [RR = 1.11, 95% CI (1.07, 1.16), P < 0.000 01]. Life quality evaluated by Kosovan performance status (KPS) showed that: life quality improvement rate of experimental group was about twice of that in control group [RR = 2.02, 95% CI (1.81, 2.26), P < 0.000 01]. Toxic and side reaction analysis showed that: the incidence of side reactions in experimental group was about 50% lower than that in control group [RR = 0.59, 95% CI (0.53, 0.66), P < 0.000 01]. Immune function test showed that: the function of experimental group was 3.2 (standard deviations) times greater than that of control group [MD = 3.23, 95% CI (2.86, 3.60), P < 0.000 01]. We can see that SFI combined with first-line chemotherapy for NSCLC can increase objective efficacy, improve life quality, decrease toxic and side reactionsinduced by chemotherapy, and improve the immune functions. As most of the included studies in this systematic evaluation had poor quality

    Abstract In this study we report the prevalence of antiretroviral drug resistant HIV-1 genotypes of virus isolated from Djiboutian patients who failed first-line antiretroviral therapy (ART) and from ART naïve patients. Patients and methods A total of 35 blood samples from 16 patients who showed first-line ART failure (>1000 viral genome copies/ml) and 19 ART-naïve patients were collected in Djibouti from October 2009 to December 2009. Both the protease (PR) and reverse transcriptase (RT) genes were amplified and sequenced using National Agency for AIDS Research (ANRS) protocols. The Stanford HIV database algorithm was used for interpretation of resistance data and genotyping. Results Among the 16 patients with first-line ART failure, nine (56.2%) showed reverse transcriptase inhibitor-resistant HIV-1 strains: two (12.5%) were resistant to nucleoside (NRTI), one (6.25%) to non-nucleoside (NNRTI) reverse transcriptase inhibitors, and six (37.5%) to both. Analysis of the DNA sequencing data indicated that the most common mutations conferring drug resistance were M184V (38%) for NRTI and K103N (25%) for NNRTI. Only NRTI primary mutations K101Q, K103N and the PI minor mutation L10V were found in ART naïve individuals. No protease inhibitor resistant strains were detected. In our study, we found no detectable resistance in ∼ 44% of all patients who experienced therapeutic failure which was explained by low compliance, co-infection with tuberculosis and malnutrition. Genotyping revealed that 65.7% of samples were infected with subtype C, 20% with CRF02_AG, 8.5% with B, 2.9% with CRF02_AG/C and 2.9% with K/C. Conclusion The results of this first study about drug resistance mutations in first-line ART failures show the importance of performing drug resistance mutation test which guides the choice of a second-line regimen. This will improve the management of HIV-infected Djiboutian patients. Virtual slides The virtual slide(s) for this article can be found here

    In patients receiving combination antiretroviral therapy (ART), switching to monotherapy with ritonavir-boosted darunavir (DRV/r) can maintain plasma HIV-1 RNA suppression with no treatment-emergent drug resistance; effects on cellular HIV-1 DNA burden are less well characterized. In MONET, patients on stable combination ART for at least 6 months with plasma HIV-1 RNA <50 copies/mL and no history of virologic failure switched to DRV/r 800/100 mg once daily, either alone (n = 127) or with 2 nucleos(t)ide reverse transcriptase inhibitors (NRTIs) (n = 129). In a representative subset of 146 patients, total HIV-1 DNA load in peripheral blood mononuclear cells (PBMC) was tested retrospectively at baseline, week 48, week 96, and week 144. Mean HIV-1 DNA levels at baseline vs week 144 were 2.50 vs 2.49 log10 copies/106 PBMC in the monotherapy arm and 2.59 vs 2.61 log10 copies/106 PBMC in the triple therapy arm, with mean (median) changes of -0.05 (-0.03) and +0.03 (+0.01) log10 copies/106 PBMC in the 2 arms, respectively. Overall baseline HIV-1 DNA levels were higher in patients with nadir CD4 counts <200 cell/µL (P<.05) and in patients who over 144 weeks experienced at least 1 HIV-1 RNA measurement >50 copies/mL (P < .05). In this substudy of the MONET trial, HIV-1 DNA levels remained stable during 144 weeks of either DRV/r monotherapy or triple therapy with DRV/r + 2 NRTIs. In both treatment arms, baseline HIV-1 DNA levels were predicted by the nadir CD4 cell count and predictive of plasma HIV-1 RNA detection during follow-up.

    The addition of an immunosuppressant (IM) after loss of response to anti-TNFα monotherapy is an emerging strategy of therapeutic optimization in patients with inflammatory bowel disease (IBD). However, few clinical data have been reported to date. We aimed to evaluate the efficacy and safety of this selective combination therapy in patients with IBD. All consecutive patients with loss of response to anti-TNFα monotherapy despite an intensive dose optimization who added an IM from October 2014 to October 2016 were entered into a prospective database. Among 630 patients treated with anti-TNFα agents during the study period, 46 (7.3%) added an IM. A total of 31 patients (67.4%) were treated with an intravenous anti-TNFα (infliximab, as originator or biosimilar), while 15 (32.6%) were treated with a subcutaneous anti-TNFα agent (10 adalimumab and 5 golimumab). The mean duration of follow-up was 12.8 ± 7.3 months. Twenty-one patients (45.7%) remained on combination therapy at the end of follow-up: 15 (32.6%) maintained a steroid-free remission, and 6 (13.0%) achieved a clinical response. In patients who experienced treatment success, the median value of C-reactive protein decreased from baseline to the end of follow-up (13.2 vs 3.0, P = 0.01; normal values <5 mg/L). Adverse events leading to treatment discontinuation were reported in 8 out of 46 patients (17.4%). In the largest cohort on this argument reported to date, the addition of an IM was an effective and safe optimization strategy after loss of response to anti-TNFα monotherapy. Low doses of IM were sufficient to achieve a clinical response. © 2018 Crohn’s & Colitis Foundation of America. Published by Oxford University Press. All rights reserved.

    To evaluate the efficacy and safety between photodynamic therapy (PDT) combined with intravitreal ranibizumab (IVR) and ranibizumab monotherapy in treating wet age-related macular degeneration (AMD). A systematic search was performed in the PubMed, Embase, Web of Science and the Cochrane Library databases through December 31, 2017. The methodological quality of the references was evaluated according to the Cochrane quality assessment. RevMan 5.3 software was used to perform the meta-analysis. Eight RCTs involving 817 participants were included. Wet AMD eyes in the mono-group achieved better best-corrected vision acuity (BCVA) than the combination group in month 12 (WMD = -0.19, 95% CI = -0.32 to -0.06, P = 0.004, I 2  = 18%). The proportion of patients gaining more than 15 letters from baseline in the mono-group was larger than that in the combination group (RR = 0.70, 95% CI: 0.56 to 0.87, P = 0.001). However, the number of ranibizumab injections with combination therapy was smaller than that with mono-therapy (MD = -1.13, 95% CI: -2.11 to -0.15, P = 0.02, I 2  = 85%). No significant differences were observed in the proportions of patients losing more than 15 letters, central retinal thickness (CRT), lesion size of choroidal neovascularization (CNV) and adverse events. Combination therapy decreased the number of injections of ranibizumab, although its BCVA improvement was inferior to that of monotherapy over 12 months of follow-up. Given the inherent limitations of the included trials, more studies are needed to further validate and update the findings in this area. Copyright © 2018 Elsevier B.V. All rights reserved.

    Several phase III clinical trials had authenticated that the addition of bevacizumab to paclitaxel plus carboplatin or gemcitabine plus cisplatin showed encouraging efficacy as first-line therapy for advanced NSCLC patients. However, the benefits of adding bevacizumab to other chemotherapy regimens in first- or second-line therapy have not been reported. To compare the clinical efficacy and safety of bevacizumab concomitant with chemotherapy regimens in patients with advanced NSCLC as first- or second-line therapy, we retrospectively reviewed the effects of adding bevacizumab to chemotherapy regimens in naive-chemotherapy and pre-chemotherapy patients with advanced non-squamous NSCLC. A total of 79 patients with advanced non-squamous NSCLC received at least two cycles of bevacizumab with chemotherapy between October 2010 and December 2013 were selected. Our primary end points were overall response rate (ORR) and disease control rate (DCR). The secondary objective was overall survival (OS) and safety. Seventy-nine patients were included in this study. Overall response rates at first evaluation (after 2 cycles) were 23.1 % (9/39) and 5.0 % (2/40) in first- and second-line therapy (P = 0.020), respectively. And disease control rates were 84.6 % (33/39) and 50 % (20/40), respectively (P = 0.001). The median OS were 27.2 months (95 % CI 13.3-41.1 months) and 29.6 months (95 % CI 6.7-52.5 months), respectively (P = 0.740). Grade 3-4 adverse events included leukopenia (2/39), and neutropenia (3/39) in first-line therapy versus neutropenia (1/40) and thrombocytopenia (2/40) in second-line treatment. In our experience, combination of bevacizumab and chemotherapy had encouraging anti-tumor efficacy as both first- and second-line therapy.

    This study evaluated the cost-effectiveness of first-line treatments of relapsing-remitting multiple sclerosis (RRMS) (dimethyl fumarate [DMF] 240 mg PO BID, teriflunomide 14 mg once daily, glatiramer acetate 20 mg SC once daily, interferon [IFN]-β1a 44 µg TIW, IFN-β1b 250 µg EOD, and IFN-β1a 30 µg IM QW) and best supportive care (BSC) in the health care payer setting in Finland. The primary outcome was the modeled incremental cost-effectiveness ratio (ICER; €/quality-adjusted life-year [QALY] gained, 3%/y discounting). Markov cohort modeling with a 15-year time horizon was employed. During each 1-year modeling cycle, patients either maintained the Expanded Disability Status Scale (EDSS) score or experienced progression, developed secondary progressive MS (SPMS) or showed EDSS progression in SPMS, experienced relapse with/without hospitalization, experienced an adverse event (AE), or died. Patients׳ characteristics, RRMS progression probabilities, and standardized mortality ratios were derived from a registry of patients with MS in Finland. A mixed-treatment comparison (MTC) informed the treatment effects. Finnish EuroQol Five-Dimensional Questionnaire, Three-Level Version quality-of-life and direct-cost estimates associated with EDSS scores, relapses, and AEs were applied. Four approaches were used to assess the outcomes: cost-effectiveness plane and efficiency frontiers (relative value of efficient treatments); cost-effectiveness acceptability frontier, which demonstrated optimal treatment to maximize net benefit; Bayesian treatment ranking (BTR); and an impact investment assessment (IIA; a cost-benefit assessment), which increased the clinical interpretation and appeal of modeled outcomes in terms of absolute benefit gained with fixed drug-related budget. Robustness of results was tested extensively with sensitivity analyses. Based on the modeled results, teriflunomide was less costly, with greater QALYs, versus glatiramer acetate and the IFNs

    In the MONotherapy in Europe with Tmc114 (MONET) trial, darunavir/ritonavir (DRV/r) monotherapy showed noninferior efficacy vs. two nucleoside reverse transcriptase inhibitors (NRTIs) plus DRV/r at the primary 48-week analysis. The trial was continued to week 144 to assess the durability of the results. A total of 256 patients with viral load < 50 HIV-1 RNA copies/mL on current highly active antiretroviral therapy (HAART) for at least 6 months switched to DRV/r 800/100 mg once daily, either as monotherapy (n=127) or with two NRTIs (n=129). Treatment failure was defined as two consecutive HIV RNA levels above 50 copies/mL [time to loss of virological response (TLOVR)] by week 144, or discontinuation of study drugs. Eighty-one per cent of patients were male and 91% were Caucasian, and they had a median baseline CD4 count of 575 cells/uL. More patients in the DRV/r monotherapy arm had hepatitis C virus coinfection at baseline than in the control arm (18% vs. 12%, respectively). By week 144, the percentage of patients with HIV RNA < 50 copies/mL [intent to treat (ITT), TLOVR, switch=failure method] was 69% vs. 75% in the DRV/r monotherapy and triple therapy arms [difference= -5.9%; 95% confidence interval (CI) -16.9%, +5.1%]; by a strict ITT analysis (switches not considered failures), the percentage of patients with HIV RNA < 50 copies/mL was 84% vs. 83.5%, respectively (difference= +0.5%; 95% CI -8.7%, +9.7%). Twenty-one and 13 patients had two consecutive HIV RNA results above 50 copies/mL in the DRV/r monotherapy arm and triple therapy arm, respectively, of whom 18 of 21 (86%) and 10 of 13 (77%) had HIV RNA < 50 copies/mL at week 144. In this study, for patients with HIV RNA < 50 copies/mL at baseline, switching to DRV/r monotherapy showed noninferior efficacy to DRV/r plus two NRTIs in a strict ITT (switches not considered failures) analysis, but not in a TLOVR switch equals failure analysis. © 2012 British HIV Association.

    Data on real-world rehospitalization risks in patients using different drugs and combination therapies for relapse prevention after a manic episode is limited. We conducted a nationwide population based cohort study using data from Swedish national registers. Swedish residents aged 18-75 years who were hospitalized for a manic episode between July 1, 2006 and December 2, 2014 were included. Prescription fills of lithium, valproate, olanzapine, quetiapine and aripiprazole were recorded throughout the first four weeks after hospital discharge, after which the patients were followed for up to one year. General and treatment specific rehospitalization risks were determined and results were adjusted for clinical and sociodemographic factors. The study included follow-up data from 6 502 hospitalizations for mania. Pharmacologic relapse prevention was used after 78% of these hospitalizations. Monotherapies and combination therapies were equally common. The average one-year rehospitalization risk for patients who did versus did not initiate prophylactic treatment was 39% and 46%, respectively. The lowest rehospitalization risks were seen in patients on combination therapy with olanzapine and valproate or olanzapine and lithium, experiencing one year rehospitalization risks of 32% and 34% (adjusted hazard ratios 0.76 (95% confidence interval [CI] 0.62-0.93) and 0.83 (95% CI 0.70-0.98), compared to lithium monotherapy). Register data does not provide information on all clinical parameters affecting treatment choices. One-year rehospitalization rates after a manic episode are considerable also for patients who initiate prophylactic treatment. Combination therapies including olanzapine and a classic mood-stabilizer may be beneficial for reducing rehospitalization risks after a manic episode. Copyright © 2017 Elsevier B.V.

    Objective: Low-dose-rate brachytherapy (LDR-BT) in localized prostate cancer is available since 15 years in Italy. We realized the first national multicentre and multidisciplinary data collection to evaluate LDR-BT practice, given as monotherapy, and outcome in terms of biochemical failure. Methods: Between May 1998 and December 2011, 2237 patients with early-stage prostate cancer from 11 Italian community and academic hospitals were treated with iodine-125 (125I) or palladium-103 LDR-BT as monotherapy and followed up for at least 2 years. 125I seeds were implanted in 97.7% of the patients: the mean dose received by 90% of target volume was 145 Gy; the mean target volume receiving 100% of prescribed dose (V100) was 91.1%. Biochemical failure-free survival (BFFS), disease-specific survival (DSS) and overall survival (OS) were estimated using Kaplan–Meier method. Log-rank test and multivariable Cox regression were used to evaluate the relationship of covariates with outcomes. Results: Median follow-up time was 65 months. 5- and 7-year DSS, OS and BFFS were 99 and 98%, 94 and 89%, and 92 and 88%, respectively. At multivariate analysis, the National Comprehensive Cancer Network score (p < 0.0001) and V100 (p = 0.09) were correlated with BFFS, with V100 effect significantly different between patients at low risk and those at intermediate/high risk (p = 0.04). Short follow-up and lack of toxicity data represent the main limitations for a global evaluation of LDR-BT. Conclusion: This first multicentre Italian report confirms LDR-BT as an excellent curative modality for low-/intermediate-risk prostate cancer. Advances in knowledge: Multidisciplinary teams may help to select adequately patients to be treated with brachytherapy, with a direct impact on the implant quality and, possibly, on outcome.

    To define factors affecting the success and long-term outcome of extracorporeal shock-wave lithotripsy (ESWL) monotherapy of partial staghorn calculi. We retrospectively reviewed 92 patients with partial staghorn calculi who were treated with ESWL monotherapy. The outcome of the treatment was evaluated after 3 months. Long-term follow-up data (>24 months) were available for 49 patients. These data were further analyzed to determine long-term outcome. At 3 months, the overall stone-free rate was 59.8%. Multiple ESWL sessions were required in 85.8% of patients. Stone surface area>500 mm2 was the only factor that significantly decreased the stone-free rate. Post-ESWL complications occurred in 12 patients (13%), among whom renal obstruction was observed in 10.8%. Secondary procedures were needed in 17 cases (18.4%). After a mean follow-up period of 7.5 years, the stone-free rate was 59.2% (29/49) and one-third of patients developed recurrence. In the long term, clinically insignificant residual fragments (CIRFs) passed spontaneously in 23% of patients, remained stable in 38.5% and became bigger in 38.5%. Regrowth of CIRFs was related to a history of stone recurrence. No patients showed deterioration of kidney function on the treated side and an improvement in pre-ESWL hydronephrosis was observed in 73.3% of patients. ESWL is suitable for staghorn stones

    TS-1, an oral fluoropyrimidine, is known to be effective for the treatment of various carcinomas including advanced/metastatic breast cancer.The Kumamoto Breast Cancer Cooperative Group(KBCCG)conducted an observational study, wherein, the efficacy and safety of TS-1 monotherapy was analyzed in 35 patients with recurrent or metastatic breast cancer.The median time to cancer progression was 3.7 months, overall response rate was 12%, and clinical benefit rate was 32%. Adverse events were observed in 27 patients(77%), and adverse events of Grade >3 were observed in 7 patients(20%). The rate of treatment-related Grade 3 and 4 adverse events increased, and was associated with poor levels of creatinine clearance(Ccr)ie <60mL/min.This study suggests that TS-1 monotherapy can potentially be used as a salvage treatment for advanced/metastatic breast cancer owing to its safety and efficacy.Measuring the level of Ccr before TS-1 therapy should be considered to avoid severe adverse events.

    Intrahepatic cholangiocarcinoma (ICC) is a rare type of liver cancer. No clinically useful prognostic factors have been reported for patients with advanced ICC. In the present study, we aimed to evaluate the clinical prognostic factors of patients with advanced ICC receiving gemcitabine plus cisplatin combination therapy (GC) as standard first-line chemotherapy. A retrospective analysis was performed of the data of patients with ICC treated at our institution from March 2011 to January 2016. We used the Cox regression model and estimated the hazard ratios of potential prognostic factors for survival. Of 216 patients with biliary tract cancer receiving GC as first-line chemotherapy, we extracted data for 77 patients who were diagnosed with ICC and received GC as first-line chemotherapy. The median overall survival was 13.8 months (95% CI, 8.9-18.6). In multivariate analysis, pretreatment serum lactate dehydrogenase (hazard ratio [HR]: 2.53, p = 0.005), C-reactive protein (HR: 3.06, p = 0.001), and carcinoembryonic antigen (HR: 2.39, p = 0.03) levels were significantly associated with overall survival. Readily available clinical laboratory values reliably predicted the prognosis of ICC patients receiving GC therapy. If validated in other studies, these results may provide a useful tool for individual patient-risk evaluation and the design and interpretation of future trials. © 2017 S. Karger AG, Basel.

    The present exploratory analysis examined the efficacy, safety, and quality-of-life effects of everolimus (EVE) + exemestane (EXE) in the subgroup of patients in BOLERO-2 whose last treatment before study entry was in the (neo)adjuvant setting. In BOLERO-2, patients with hormone-receptor-positive (HR(+)), human epidermal growth factor receptor-2-negative (HER2(-)) advanced breast cancer recurring/progressing after a nonsteroidal aromatase inhibitor (NSAI) were randomly assigned (2:1) to receive EVE (10 mg/day) + EXE (25 mg/day) or placebo (PBO) + EXE. The primary endpoint was progression-free survival (PFS) by local assessment. Overall, 137 patients received first-line EVE + EXE (n = 100) or PBO + EXE (n = 37). Median PFS by local investigator assessment nearly tripled to 11.5 months with EVE + EXE from 4.1 months with PBO + EXE (hazard ratio = 0.39; 95 % CI 0.25-0.62), while maintaining quality of life. This was confirmed by central assessment (15.2 vs 4.2 months; hazard ratio = 0.32; 95 % CI 0.18-0.57). The marked PFS improvement in patients receiving EVE + EXE as first-line therapy for disease recurrence during or after (neo)adjuvant NSAI therapy supports the efficacy of this combination in the first-line setting. Furthermore, the results highlight the potential benefit of early introduction of EVE + EXE in the management of HR(+), HER2(-) advanced breast cancer in postmenopausal patients.

    Despite advances in cytotoxic chemotherapy and targeted therapies, 5-year survival rates remain low for patients with advanced breast cancer at diagnosis. This highlights the limited effectiveness of current treatment options. An improved understanding of cellular functions associated with the development and progression of breast cancer has resulted in the creation of a number of novel targeted molecular therapies. However, more work is needed to improve outcomes, particularly in the first-line recurrent or metastatic hormone receptor–positive breast cancer setting. The phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin (mTOR) pathway is a major intracellular signaling pathway that is often upregulated in breast cancer, and overactivation of this pathway has been associated with primary or developed resistance to endocrine treatment. Clinical data from the Phase III Breast Cancer Trials of Oral Everolimus-2 (BOLERO-2) study of the mTOR inhibitor everolimus combined with exemestane in hormone receptor–positive advanced breast cancer were very promising, highlighting the potential role of mTOR inhibitors in combination with endocrine therapies as a first-line treatment option for these patients. It is hoped that the use of mTOR inhibitors combined with current standard-of-care endocrine therapies, such as aromatase inhibitors, in the first-line advanced breast cancer setting may result in greater antitumor effects and also delay or reverse treatment resistance.

    The present study examined real-world direct health care costs for metastatic colorectal cancer (mCRC) patients initiating first-line (1L) bevacizumab (BEV)- or cetuximab (CET)-containing regimen in 1L or 1L-through-second-line (1L-2L) therapy. Using a large US insurance claims database, patients with mCRC initiating 1L BEV- or 1L CET-containing regimen from January 1, 2008 to September 30, 2014 were identified. The per-patient per-month (PPPM) all-cause health care costs (2014 US dollars) were measured during 1L therapy and, for patients continuing to a 2L biologic-containing regimen, 1L-2L therapy. Multivariable regression analyses were used to compare PPPM total health care costs between patients initiating a 1L BEV- versus 1L CET-containing regimen. A total of 6095 patients initiating a 1L BEV- and 453 initiating a 1L CET-containing regimen were evaluated for 1L costs; 2218 patients initiating a 1L BEV- and 134 initiating a 1L CET-containing regimen were evaluated for 1L-2L costs. In 1L therapy, 1L CET had adjusted PPPM costs that were $3135 (95% confidence interval [CI], $1174-$5040; P < .001) greater on average than 1L BEV. In 1L-2L therapy, 1L BEV-2L CET had adjusted PPPM costs that were $1402 (95% CI, $1365-$1442; P = .010) greater than those for 1L BEV-2L BEV, and 1L CET-2L BEV had adjusted PPPM costs that were $4279 (95% CI, $4167-$4400; P = .001) greater on average than those for 1L BEV-2L BEV. The adjusted PPPM cost differences for 1L BEV-2L other biologic or 1L CET-2L other biologic agent were numerically greater but statistically insignificant. PPPM total health care costs for 1L and 2L therapy tended to be greater for patients treated with 1L CET-containing regimens than for 1L BEV-containing regimens. Also, continuing treatment with BEV-containing regimens 1L-2L was less costly than switching between BEV and CET. The cost differences between BEV and CET hold important implications for treatment decisions of mCRC patients in real-world clinical

    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.

    Mutation rates at two expanded simple tandem repeat loci were studied in the germ line of first- and second-generation offspring of inbred male CBA/H, C57BL/6, and BALB/c mice exposed to either high linear energy transfer fission neutrons or low linear energy transfer x-rays. Paternal CBA/H exposure to either x-rays or fission neutrons resulted in increased mutation rates in the germ line of two subsequent generations. Comparable transgenerational effects were observed also in neutron-irradiated C57BL/6 and x-irradiated BALB/c mice. The levels of spontaneous mutation rates and radiation-induced transgenerational instability varied between strains (BALB/c>CBA/H>C57BL/6). Pre- and postmeiotic paternal exposure resulted in similar increases in mutation rate in the germ line of both generations of CBA/H mice, which together with our previous results suggests that radiation-induced expanded simple tandem repeat instability is manifested in diploid cells after fertilization. The remarkable finding that radiation-induced germ-line instability persists for at least two generations raises important issues of risk evaluation in humans. PMID:11997464

    To present the impact of treatments on health-related quality of life (HRQoL) from the double-blind, randomised phase III COMBI-d study that investigated the combination of dabrafenib and trametinib versus dabrafenib monotherapy in patients with BRAF V600E/K-mutant metastatic melanoma. COMBI-d showed significantly prolonged progression-free survival for the combination. HRQoL was evaluated using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-C30, a generic cancer questionnaire (completed at baseline, during study treatment, at progression and post progression) assessing various dimensions (global health/QoL, functional status, and symptom impact). A mixed-model, repeated-measures analyses of covariance evaluated differences between arms. Questionnaire completion rates were >95% at baseline, >85% to week 40 and >70% at disease progression. Baseline scores across both arms were comparable for all dimensions. Global health dimension scores were significantly better at weeks 8, 16 and 24 for patients receiving the combination during treatment and at progression. The majority of functional dimension scores (physical, social, role, emotional and cognitive functioning) trended in favour of the combination. Pain scores were significantly improved and clinically meaningful (6-13 point difference) for patients receiving the combination for all follow-up assessments versus those receiving dabrafenib monotherapy. For other symptom dimensions (nausea and vomiting, diarrhoea, dyspnoea, and constipation), scores trended in favour of dabrafenib monotherapy. This analysis demonstrates that the combination of dabrafenib and trametinib provides better preservation of HRQoL and pain improvements versus dabrafenib monotherapy while also delaying progression.

    Sevelamer hydrochloride/carbonate (SH/C) and lanthanum carbonate (LC) are noncalcium-based phosphate binders used for the management of hyperphosphatemia in patients with end-stage renal disease (ESRD). The objectives of this study were to examine the dose-relativity, tablet burden, and cost difference of bidirectional conversion between SH/C and LC monotherapy in a large cohort of real-world patients with ESRD. This retrospective cohort study included three 30-day preconversion periods (days -90 to -61, -60 to -31, and -30 to -1) followed by three 30-day postconversion periods (days 1 to 30, 31 to 60, and 61 to 90); day 0 was the index date of conversion. The full analysis population (FAP) comprised two cohorts: SH/C to LC (S-L) converters and LC to SH/C (L-S) converters. The SH/C:LC dose-relativity ratio was assessed in the dose-relativity subset, defined as patients whose serum phosphate levels fell within a caliper range of ± 0.5 mg/dL in the final preconversion (days -30 to -1) and postconversion (days 61 to 90) periods. Tablet burden and phosphate binder costs were assessed in the FAP. Phosphate binder costs were based on average wholesale prices. The FAP contained a total of 303 patients, comprising the S-L (128 patients) and L-S (175 patients) converter cohorts. The dose-relativity subset contained 159 patients, 72 from the S-L cohort and 87 from the L-S cohort. The overall mean SH/C:LC dose-relativity ratio was 2.27 (95% CI, 2.04 to 2.52). In SH/C dose strata >800 to 2400, >2400 to 4800, >4800 to 7200, and >7200 mg/d, overall mean dose-relativity ratios were 0.79 (95% CI, 0.57 to 1.10), 1.45 (95% CI, 1.20 to 1.75), 2.05 (95% CI, 1.75 to 2.39), and 3.24 (95% CI, 2.89 to 3.66), respectively. The overall mean tablet burden was 6.6 tablets per day lower with LC monotherapy than with SH/C monotherapy (95% CI, -7.1 to -6.0; P < 0.0001). The overall mean binder cost/patient per month was $1080.40 for SH/C compared with $1006.20 for LC, corresponding to a mean

    We detect the persistence of the solidification and order-disorder first-order transition lines in the phase diagram of nanocrystalline Bi_{2}Sr_{2}CaCu_{2}O_{8} vortex matter down to a system size of less than one hundred vortices. The temperature location of the vortex solidification transition line is not altered by decreasing the sample size although there is a depletion of the entropy jump at the transition with respect to macroscopic vortex matter. The solid order-disorder phase transition field moves upward on decreasing the system size due to the increase of the surface-to-volume ratio of vortices entailing a decrease on the average vortex binding energy.

The solid order-disorder phase transition field moves upward on decreasing the system size due to the increase of the surface-to-volume ratio of vortices entailing a decrease on the average vortex binding energy.

    The 2013 American College of Cardiology/American Heart Association guidelines on cholesterol management placed greater emphasis on statin therapy given the well-established benefits in primary and secondary prevention of cardiovascular disease. Residual risk may remain after statin initiation, in part because of triglyceride-rich lipoprotein cholesterol. Several large trials have failed to show benefit with non-statin cholesterol-lowering medications in the reduction of cardiovascular events. Yet, subgroup analyses showed a benefit in those with hypertriglyceridemia and lower high-density lipoprotein cholesterol level, a high-risk pattern of dyslipidemia. This review discusses the benefits of omega-3 carboxylic acids, a recently approved formulation of omega-3 fatty acid with enhanced bioavailability, in the treatment of dyslipidemia both as monotherapy and combination therapy with a statin.

    While laser resurfacing remains the most effective treatment option for atrophic acne scars, the high incidence of post-treatment adverse effects limits its use. Fractional laser photothermolysis attempts to overcome these limitations of laser resurfacing by creating microscopic zones of injury to the dermis with skip areas in between. The aim of the present study is to assess the efficacy and safety of fractional CO2 laser resurfacing in atrophic facial acne scars. Sixty patients with moderate to severe atrophic facial acne scars were treated with 3-4 sessions of fractional CO2 laser resurfacing at 6-week intervals. The therapeutic response to treatment was assessed at each follow up visit and then finally 6 months after the last laser session using a quartile grading scale. Response to treatment was labelled as 'excellent' if there was >50% improvement in scar appearance and texture of skin on the grading scale while 25-50% response and <25% improvement were labelled as 'good' and 'poor' response, respectively. The overall satisfaction of the patients and any adverse reactions to the treatment were also noted. Most of the patients showed a combination of different morphological types of acne scars. At the time of final assessment 6 months after the last laser session, an excellent response was observed in 26 patients (43.3%) while 15 (25%) and 19 patients (31.7%) demonstrated a good and poor response respectively. Rolling and superficial boxcar scars responded the best while pitted scars responded the least to fractional laser monotherapy. The commonest reported adverse effect was transient erythema and crusting lasting for an average of 3-4 and 4-6 days, respectively while three patients developed post-inflammatory pigmentation lasting for 8-12 weeks. Fractional laser resurfacing as monotherapy is effective in treating acne scars especially rolling and superficial boxcar scars with minimal adverse effects.

    The present study was designed to assess possible relationships between deterioration of the glycated hemoglobin (HbA1c)-lowering effects in dipeptidyl peptidase-4 inhibitor (DPP4i) monotherapy and macronutrient intake among individuals with type 2 diabetes. Type 2 diabetes patients who began and continued DPP4i monotherapy without any prescription change for 1 year were retrospectively stratified into two groups: (i) patients who maintained their HbA1c levels during the 0.5- to 1-year period after DPP4i initiation (group A, ΔHbA1c [1-0.5 year] <0.4%, n = 53); and (ii) those whose HbA1c levels increased [group B, ΔHbA1c (1-0.5 year] ≥0.4%, n = 10). Group B had significantly higher ΔHbA1c (1-0.5 year), Δbodyweight (1-0.5 year) and fat intake, especially of saturated and monounsaturated fats; the carbohydrate and protein intake were similar between groups. Multiple regression analyses showed that fat intake, especially saturated fat intake, was significantly correlated with ΔHbA1c (1-0.5 year). Thus, dietary habits, especially saturated fat intake, might well contribute to deterioration of the HbA1c-lowering effects in DPP4i monotherapy. © 2017 The Authors.

    Recently, the Keck interferometer was upgraded to do self-phase-referencing (SPR) assisted K-band spectroscopy at R ~ 2000. This means, combining a spectral resolution of 150 km/s with an angular resolution of 2.7 mas, while maintaining high sensitiviy. This SPR mode operates two fringe trackers in parallel, and explores several infrastructural requirements for off-axis phase-referencing, as currently being implemented as the KI-ASTRA project. The technology of self-phasereferencing opens the way to reach very high spectral resolution in near-infrared interferometry. We present the scientific capabilities of the KI-SPR mode in detail, at the example of observations of the Be-star 48 Lib. Several spectral lines of the cirumstellar disk are resolved. We describe the first detection of Pfund-lines in an interferometric spectrum of a Be star, in addition to Br γ. The differential phase signal can be used to (i) distinguish circum-stellar line emission from the star, (ii) to directly measure line asymmetries tracing an asymetric gas density distribution, (iii) to reach a differential, astrometric precision beyond single-telescope limits sufficient for studying the radial disk structure. Our data support the existence of a radius-dependent disk density perturbation, typically used to explain slow variations of Be-disk hydrogen line profiles.

    As the standard first-line treatment for advanced non-small cell lung cancer (NSCLC) with activating epidermal growth factor receptor (EGFR) mutation, EGFR-tyrosine kinase inhibitors (EGFR-TKIs) have significantly improved the median progression-free survival (PFS) up to 18.9 months. However, almost all patients eventually develop acquired resistance to EGFR-TKIs, which limits the first-line PFS. To overcome the resistance and improve overall survival, researchers have tried to identify the resistance mechanisms and develop new treatment strategies, among which a combination of EGFR-TKIs and cytotoxic chemotherapy is one of the hotspots. The data from preclinical and clinical studies on combined EGFR-TKIs and chemotherapy have shown very interesting results. Here, we reviewed the available preclinical and clinical studies on first-line EGFR-TKIs-chemotherapy combination in patients with advanced NSCLC harboring activating EGFR mutation, aiming to provide evidences for more potential choices and shed light on clinical treatment.

    Vonoprazan (VPZ)-based triple therapy has been reported to have greater efficacy than a proton pump inhibitor (PPI)-based triple therapy for Helicobacter pylori (H. pylori) eradication. However, because VPZ is more expensive than PPIs such as rabeprazole (RPZ), economic evaluation is essential. We performed a retrospective study on 209 patients who underwent first-line eradication of H. pylori infection in Fuyoukai Murakami Hospital from 1 March 2015 to 31 March 2016. Patients who received VPZ, amoxicillin (AMPC) and clarithromycin (CAM) were assigned to the VPZ/AC group (n = 111) and patients who received RPZ, AMPC and CAM to the RPZ/AC group (n = 98). We compared the patients' backgrounds, including age, gender, use of high-dose CAM, past history of peptic ulcer, smoking and drug-related adverse events between the two groups. We defined cost as direct medical costs per patient and effectiveness as the first-line eradication rate in the intention-to-treat (ITT) analysis and analyzed the cost-effectiveness using the cost-effectiveness ratio (CER) and incremental cost-effectiveness ratio (ICER). There was no significant difference in the patients' backgrounds. The ITT analysis revealed an eradication rate of 94.6% for VPZ/AC and 86.7% for RPZ/AC. VPZ/AC cost 1155.4 Japanese yen (JPY) higher than RPZ/AC (34063.4 vs. 32908.0, JPY). CER of VPZ/AC was less than that of RPZ/AC (360.1 vs. 379.4, JPY per percent) and ICER of VPZ/AC was 147.0 JPY (1.28 Euro (EUR), 1 EUR =115 JPY) per percent. VPZ/AC was more cost-effective than RPZ/AC as first-line therapy for H. pylori eradication.

    This article presents a case study on developing a software product line for data acquisition systems in astronomy based on the Exemplar Driven Development methodology and the Exemplar Flexibilization Language tool. The main strategies to build the software product line are based on the domain commonality and variability, the incremental scope and the use of existing artifacts. It consists on a lean methodology with little impact on the organization, suitable for small projects, which reduces product line start-up time. Software Product Lines focuses on creating a family of products instead of individual products. This approach has spectacular benefits on reducing the time to market, maintaining the know-how, reducing the development costs and increasing the quality of new products. The maintenance of the products is also enhanced since all the data acquisition systems share the same product line architecture.

    The availability of tyrosine kinase inhibitors has extended therapeutic options for chronic myeloid leukaemia (CML) patients. Monitoring recommendations and clinical response goals have recently been updated. The objective of this study was to describe the profile of CML patients in chronic phase currently receiving first-line therapy, including treatment, monitoring and response kinetics. A multicentre, cross-sectional, epidemiological survey in unselected chronic phase CML patients in France attending consultations during a one-month period was performed. 438 of 697 (62·8%) reported patients were currently receiving first-line treatment and were analysed. Imatinib was the most frequently received treatment (72·4% of patients). Retrospective cytogenetic and molecular assessments at 3, 6, 12 or 18 months were available in 88·4% of patients. At the 12-month assessment, 32·2% were not in major molecular response (MMR). At last assessment, among 355 patients with duration of treatment ≥ 12 months, 91·5% had achieved MMR and 66·5% were in deep molecular response. This study, performed in everyday practice population of CML patients, suggests that monitoring of molecular responses in real-life practice is aligned with European LeukaemiaNet recommendations. The majority of patients still receiving first-line treatment are in optimal response, with a few being classified as in the warning area or responding to failure. © 2016 John Wiley & Sons Ltd.

    To describe the relative health and economic outcomes associated with different second-line therapeutic approaches to manage glycaemia in older type 2 diabetes patients requiring escalation from metformin monotherapy. The Clinical Practice Research Datalink database was used to inform a retrospective observational cohort study of patients with type 2 diabetes treated with metformin monotherapy requiring escalation (addition or switch) to a second-line oral regimen from January 1, 2008 to December 31, 2014. Primary outcomes included time to first event (any event, myocardial infarction [MI], stroke, or composite of MI/stroke [major adverse cardiovascular event; MACE]) and total event rate. The health economic consequences associated with the choice of second-line treatment in older patients were assessed using the CORE Diabetes Model. A total of 10 484 patients were included; the majority escalated to second-line treatment with metformin + sulphonylurea (SU; 42%) or switched to SU monotherapy (28%). In multivariate adjusted analyses, total event rates for MACE with metformin + dipeptidyl peptidase-4 (DPP-4) inhibitor were significantly lower than with metformin + SU (0.61, 95% confidence interval [CI] 0.39-0.98), driven by a lower MI rate in the metformin + DPP-4 inhibitor group (0.52, 95% CI 0.27-0.99). Economic analyses estimated that metformin + DPP-4 inhibitor treatment was associated with the largest gain in health benefit, and cost-effectiveness ratios were favourable (<£30 000 per quality-adjusted life-year) for all second-line treatment scenarios. With respect to treatment choice, data from the present study support the notion of prescribing beyond metformin + SU, as alternative regimens have been shown to be associated with reduced outcomes risk and value for money. © 2016 The Authors.

    We evaluated whether combination therapy with transcutaneous electrical nerve stimulation and oxybutynin results in a superior treatment response compared to either therapy alone in children with urge incontinence. In this placebo controlled study 66 children with a mean ± SD age of 7.3 ± 1.6 years who were diagnosed with urge incontinence were randomized to 3 treatment groups. Group 1 consisted of 22 children undergoing transcutaneous electrical nerve stimulation plus active oxybutynin administration. Group 2 included 21 children undergoing active transcutaneous electrical nerve stimulation plus placebo oxybutynin administration. Group 3 consisted of 23 children undergoing active oxybutynin administration plus placebo transcutaneous electrical nerve stimulation. The children received active or placebo transcutaneous electrical nerve stimulation over the sacral S2 to S3 outflow for 2 hours daily in combination with 5 mg active or placebo oxybutynin twice daily. The intervention period was 10 weeks. Primary outcome was number of wet days weekly. Secondary outcomes were severity of incontinence, frequency, maximum voided volume over expected bladder capacity for age, average voided volume over expected bladder capacity for age and visual analogue scale score. Combination therapy was superior to oxybutynin monotherapy, with an 83% greater chance of treatment response (p = 0.05). Combination therapy was also significantly more effective than transcutaneous electrical nerve stimulation monotherapy regarding reduced number of wet days weekly (mean difference -2.28, CI -4.06 to -0.49), severity of incontinence (-3.11, CI -5.98 to -0.23) and daily voiding frequency (-2.82, CI -4.48 to -1.17). Transcutaneous electrical nerve stimulation in combination with oxybutynin for childhood urge incontinence was superior to monotherapy consisting of transcutaneous electrical nerve stimulation or oxybutynin, although the latter only reached borderline statistical significance

    In 11 of 12 eyes with chronic simple glaucoma after surgery for retinal detachment, intraocular pressures were decreased for one to 5 1/2 years without any antiglaucomatous treatment. No further deterioration in the state of the optic disks or the visual fields occurred in any of these eyes. In all 12 fellow eyes antiglaucomatous treatment is still being administered. The operation employed in nine of the 11 cases consisted of an encircling silicone rubber band shortened by 15 to 20% of its length when placed around the eyeball before tapping subretinal fluid. An episcleral silicone implant was placed under the encircling ban in seven of these eyes. Kinking and possibly narrowing of the long posterior ciliary arteries by the encircling silicone band probably caused the ciliary hyposecretion and the resultant hypotony.

    First-line postoperative adjuvant chemotherapies with S-1 and capecitabine and oxaliplatin (XELOX) were first recommended for resectable gastric cancer patients in the 2010 and 2011 Chinese NCCN Clinical Practice Guidelines in Oncology: Gastric Cancer; however, their economic impact in China is unknown. The aim of this study was to compare the cost-effectiveness of adjuvant chemotherapy with XELOX, with S-1 and no treatment after a gastrectomy with extended (D2) lymph-node dissection among patients with stage II-IIIB gastric cancer. A Markov model, based on data from two clinical phase III trials, was developed to analyse the cost-effectiveness of patients in the XELOX group, S-1 group and surgery only (SO) group. The costs were estimated from the perspective of Chinese healthcare system. The utilities were assumed on the basis of previously published reports. Costs, quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios (ICER) were calculated with a lifetime horizon. One-way and probabilistic sensitivity analyses were performed. For the base case, XELOX had the lowest total cost ($44,568) and cost-effectiveness ratio ($7,360/QALY). The relative scenario analyses showed that SO was dominated by XELOX and the ICERs of S-1 was $58,843/QALY compared with XELOX. The one-way sensitivity analysis showed that the most influential parameter was the utility of disease-free survival. The probabilistic sensitivity analysis predicted a 75.8% likelihood that the ICER for XELOX would be less than $13,527 compared with S-1. When ICER was more than $38,000, the likelihood of cost-effectiveness achieved by S-1 group was greater than 50%. Our results suggest that for patients in China with resectable disease, first-line adjuvant chemotherapy with XELOX after a D2 gastrectomy is a best option comparing with S-1 and SO in view of our current study. In addition, S-1 might be a better choice, especially with a higher value of willingness-to-pay threshold.

    "Clinical inertia" has been used to describe the delay in the intensification of type 2 diabetes treatment among patients with poor glycemic control. Previous studies may have exaggerated the prevalence of clinical inertia by failing to adequately monitor drug dose changes and nonmedication interventions. This project evaluated the intensification of diabetes therapy and hemoglobin A1c (A1C) goal attainment among patients with newly diagnosed type 2 diabetes when metformin monotherapy failed. The electronic health record at Cleveland Clinic was used to identify patients with newly diagnosed type 2 diabetes between 2005 and 2013 who failed to reach the A1C goal after 3 months of metformin monotherapy. A time-dependent survival analysis was used to compare the time until A1C goal attainment in patients who received early intensification of therapy (within 6 months of metformin failure) or late intensification. The analysis was performed for A1C goals of 7% (n = 1,168), 7.5% (n = 679), and 8% (n = 429). Treatment was intensified early in 62%, 69%, and 72% of patients when poor glycemic control was defined as an A1C >7%, >7.5%, and >8%, respectively. The probability of undergoing an early intensification was greater the higher the A1C category. Time until A1C goal attainment was shorter among patients who received early intensification regardless of the A1C goal (all P < 0.05). A substantial number of patients with newly diagnosed type 2 diabetes fail to undergo intensification of therapy within 6 months of metformin monotherapy failure. Early intervention in patients when metformin monotherapy failed resulted in more rapid attainment of A1C goals. © 2016 by the American Diabetes Association.

    Valsartan is known to inhibit platelet activity in both in vitro and ex vivo clinical setting, whereas aliskiren in vitro modulates antithrombin-III in plasma. The authors tested how aliskiren and valsartan combination versus aliskiren monotherapy will affect hemostatic biomarkers in mild-to-moderate hypertensive diabetics in the frame of the Aliskiren and Valsartan Impact in Diabetics (AVID) trial. A total of 52 patients with type 2 diabetes and mild-to-moderate hypertension were equally randomized to aliskiren (150-300 mg/d) and valsartan (160 mg/d) versus aliskiren (150-300 mg/d) alone for 4 weeks. A total of 25 biomarkers were serially measured, of which 16 are related to platelet function, 6 to coagulation, and 3 to fibrinolysis. Aliskiren monotherapy has no significant impact on any of the assessed biomarkers. In contrast, valsartan on top of aliskiren provided significant inhibition of ADP-induced platelet aggregation (P=0.032), decreased shear-induced activation measured with PFA-100 analyzer (P=0.041), and diminished expression of GP IIb/IIIa activity (P=0.027) measured by PAC-1 antibody, GP Ib (CD42b, P=0.033), vitronectin receptor (CD51/61, P=0.046), P-selectin (CD62p, P=0.026), lysosome-associated membrane protein (CD107a, P=0.042), and CD40-ligand (CD154, P=0.048). In AVID trial, valsartan in combination with aliskiren mildly but significantly inhibited platelets, confirming previous observations. In contrast, aliskiren monotherapy does not enhance antithrombin activity, suggesting that previous data probably represent a laboratory artifact. Importantly, these randomized data were generated on top of low-dose daily aspirin, supporting extra benefit for combination use of angiotensin receptor blockers and renin inhibitors in high-risk diabetic population.

    In order to prevent the occurrence of drug-resistant mutants associated with treatment for chronic hepatitis B virus (HBV) infection, combination therapy is being developed. To determine the efficacy of adefovir dipivoxil (ADV) plus emtricitabine (FTC) combination therapy in chronic HBV infection. Thirty treatment-nai ve, HBeAg-positive patients were randomized to combination ADV plus FTC (n=14) or ADV plus placebo monotherapy (n=16) for 96 weeks. HBV DNA was measured by polymerase chain reaction. Treatment was stopped in those with HBeAg seroconversion. The median decrease in HBV DNA at week 96 was higher in the combination group (-5.30 vs. -3.98 log(10)copies/ml, p=0.05). More patients in the combination group had normalization of alanine aminotransaminase and HBV DNA<300 copies/ml at week 96 when compared with the monotherapy group [11 of the 14 patients (78.6%) vs. 6 of the 16 patients (37.5%), p=0.03]. However, HBeAg seroconversion at week 96 was similar in the 2 groups [2/14 (14.3%) vs. 4/16 (25.0%), p=NS]. No ADV or FTC resistance was detected at week 96. In those with HBeAg seroconversion, 50.0% had post-treatment relapse. Combination ADV plus FTC resulted in more potent suppression of HBV DNA over 96 weeks of therapy.

    INTRODUCTION Chronic neuropathic pain is difficult to treat and is often refractory to most modalities of treatment. Ziconotide is a novel, potent, non-opioid, calcium channel blocking agent which has been shown in clinical trials to be effective in treating chronic neuropathic pain. METHODS EMBASE, MEDLINE, CINAHL Plus and Web of Science electronic databases were searched for English language studies. Reference sections of articles were examined for further papers and the manufacturer of ziconotide was contacted for further unpublished data. Three randomised controlled trials in ziconotide monotherapy were included and subjected to a random effects meta-analysis. RESULTS All three studies used the similar main outcome measure (visual analogue scale of pain intensity; VASPI) and were therefore comparable. A Jadad score was performed for each paper. Frequent serious adverse events (SAEs) were observed which resulted in two of the studies revising the protocol. The meta-analysis revealed a pooled odds ratio (responders on ziconotide vs. placebo) of 2.77 (95% CI, 1.37 to 5.59). DISCUSSION The results suggest that ziconotide is beneficial for pain reduction in chronic neuropathic pain. However, there remain some methodological issues that may call into question the validity of the results. It is evident that more work needs to be conducted to further validate the efficacy of ziconotide and to discover new areas of use. PMID:26861472

    OBJECTIVE To assess efficacy and safety of lixisenatide monotherapy in type 2 diabetes. RESEARCH DESIGN AND METHODS Randomized, double-blind, 12-week study of 361 patients not on glucose-lowering therapy (HbA1c 7–10%) allocated to one of four once-daily subcutaneous dose increase regimens: lixisenatide 2-step (10 μg for 1 week, 15 μg for 1 week, and then 20 μg; n = 120), lixisenatide 1-step (10 μg for 2 weeks and then 20 μg; n = 119), placebo 2-step (n = 61), or placebo 1-step (n = 61) (placebo groups were combined for analyses). Primary end point was HbA1c change from baseline to week 12. RESULTS Once-daily lixisenatide significantly improved HbA1c (mean baseline 8.0%) in both groups (least squares mean change vs. placebo: −0.54% for 2-step, −0.66% for 1-step; P < 0.0001). Significantly more lixisenatide patients achieved HbA1c <7.0% (52.2% 2-step, 46.5% 1-step) and ≤6.5% (31.9% 2-step, 25.4% 1-step) versus placebo (26.8% and 12.5%, respectively; P < 0.01). Lixisenatide led to marked significant improvements of 2-h postprandial glucose levels and blood glucose excursions measured during a standardized breakfast test. A significant decrease in fasting plasma glucose was observed in both lixisenatide groups versus placebo. Mean decreases in body weight (∼2 kg) were observed in all groups. The most common adverse events were gastrointestinal—nausea was the most frequent (lixisenatide 23% overall, placebo 4.1%). Symptomatic hypoglycemia occurred in 1.7% of lixisenatide and 1.6% of placebo patients, with no severe episodes. Safety/tolerability was similar for the two dose regimens. CONCLUSIONS Once-daily lixisenatide monotherapy significantly improved glycemic control with a pronounced postprandial effect (75% reduction in glucose excursion) and was safe and well tolerated in type 2 diabetes.

Repaglinide stimulates insulin release from beta-cells only in the presence of glucose. Two placebo-controlled studies were performed to establish the effective dose range of repaglinide. In one study, repaglinide (0.25-4.0 mg preprandially) caused a dose-dependent decrease in blood glucose and a non-dose-dependent increase in insulin over 4 weeks (all doses p < 0.001 vs. placebo). In the second study, repaglinide (0.25-8.0 mg preprandially) was titrated over 6 weeks to obtain the optimum response (fasting plasma glucose < 8.9 mmol/L). The titration period was followed by a 12-week dose-maintenance period. At the end of the study, repaglinide had decreased fasting plasma glucose by 3.4 mmol/L (p < 0.05) and 2-h postprandial blood glucose by 5.8 mmol/L (p < 0.001) versus placebo. Glycated haemoglobin (HbA1c) decreased significantly from 8.5% to 7.9% in the repaglinide group and increased significantly from 8.1% to 9.2% in the placebo group (p < 0.001 between groups). In five 1-year, multicentre, randomized, double-blind, phase III trials, repaglinide (0.5-4.0 mg preprandially) was compared with the sulphonylureas glibenclamide, glipizide and gliclazide. Repaglinide was more effective than glipizide at maintaining glycaemic control and was equivalent to glibenclamide and gliclazide on the basis of change in HbA1c. Hypoglycaemic events were reported in 16% of repaglinide-treated patients and 15-20% of sulphonylurea-treated patients. These data indicate that repaglinide monotherapy, with diet and exercise, is effective in patients with Type 2 diabetes.

    Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) such as gefitinib can provide better efficacy and prolonged progression free survival (PFS) than cytotoxic chemotherapy for metastatic lung non-squamous cell carcinoma harboring susceptible EGFR mutations when used as first-line therapy. Cytotoxic chemotherapy is regarded as being the standard therapy to overcome acquired resistance to an initial EGFR TKI. However, there is currently no consensus on how best to treat patients who develop resistance to both an initial EGFR TKI and chemotherapy. We enrolled stage IV lung adenocarcinoma patients with an EGFR mutation and who had developed acquired resistance to gefitinib and cytotoxic chemotherapy from two university-affiliated hospitals in Taiwan from June 2011 to December 2014. Basic demographic data, included Eastern Cooperative Oncology Group (ECOG) performance status were collected, and the response rate, progression-free survival (PFS) and overall survival (OS) were analyzed. Two hundred and nine patients with mutated EGFR and who took gefitinib as the first-line therapy were identified in the study period, of whom 86 received second-line cytotoxic chemotherapy, and 60 who received third-line therapy were eligible for this study. The patients who received cytotoxic chemotherapy had a significantly higher disease control rate than those who received erlotinib (73% vs. 46%, p = 0.0363), however there were no significant differences in PFS (2.9 months vs. 3.1 months, p = 0.9049) and OS (8.9 months vs. 7.9 months, p = 0.4956). Platinum- or pemetrexed-based chemotherapy provided similar PFS and OS as others did. The only significant poor prognostic factors for OS were old age (≥65 years) (HR = 5.97 [2.65-13.44], p < 0.0001) and poor performance status (ECOG ≥2) (HR = 5.84 [2.61-13.09], p < 0.0001). Retreatment with an EGFR TKI is not inferior to cytotoxic chemotherapy when used as salvage therapy for patients

    Background Chronic myeloid leukemia (CML) has a low incidence but a high burden of disease, and is treated with high-cost tyrosine kinase inhibitors (TKI). Objective To determine the time from the start of a first-line TKI until it passes to second-line, and to establish the reasons for the change of therapy time. Setting Patients with Philadelphia-positive CML treated with some TKI. Methods Retrospective cohort study, between January 1 2007 and July 31 2015, with information obtained from medical records, the time to change initial drugs to secondline therapy, and the reasons for change, were identified. Kaplan-Meier survival analysis was carried out. Main outcome measure A change in therapy to the secondline TKI and the final reason for the change of therapy. Results A total of 247 patients treated were found in 22 cities in Colombia with a mean age of 53.2 ± 15.2 years. The drug most used as initial therapy was imatinib; 53.8% of cases had to change to another TKI. 50% of patients changed therapy in 42 months, men in 24 and women in 67 months (95% CI 14.314-33.686; p = 0.001). Being male (OR 2.23; 95% CI 1.291-3.854; p = 0.004) and receiving hydroxyurea (OR 3.65; 95% CI 1.601-8.326; p = 0.002) were associated with a higher probability of switching to nilotinib or dasatinib, while receiving a new-generation TKI (OR 0.15; 95% CI 0.071-0.341; p < 0.001) reduced this risk. Conclusions A high proportion of patients needed to change to a second line with nilotinib and dasatinib management. It is necessary to obtain more real world evidence, to improve the effectiveness, adherence and safety of the treatment.

    AIM: To evaluate long-term outcomes of radiofrequency (RF) ablation as first-line therapy for single hepatocellular carcinoma (HCC) ≤ 3 cm and to determine survival and prognostic factors. METHODS: We included all 184 patients who underwent RF ablation as a first-line treatment for single HCC ≤ 3 cm between April 2005 and December 2013. According to the criteria of Livraghi, the 184 patients were divided into two groups: those suitable for surgical resection (84 cases) and those unsuitable for surgical resection (100 cases). The primary endpoints were the overall survival (OS) rate and safety; the secondary endpoints were primary technique effectiveness and recurrence rate. RESULTS: There were 19 (10.3%) cases of ablation related minor complications. The complete tumor ablation rate after one RF session was 97.8% (180/184). The rate of local tumor progression, extrahepatic metastases and intrahepatic distant recurrence were 4.9% (9/184), 9.8% (18/184) and 37.5% (69/184), respectively. In the 184 patients, the 1-, 3-, and 5-year OS rates were 99.5%, 81.0%, and 62.5%, respectively. The 1-, 3-, and 5-year OS rates were 100%, 86.9%, and 71.4%, respectively, in those suitable for surgical resection and 99.0%, 76.0%, and 55.0%, respectively, in those unsuitable for surgical resection (P = 0.021). On univariate and multivariate analyses, poorer OS was associated with Child-Pugh B class and portal hypertension (P < 0.05). CONCLUSION: RF ablation is a safe and effective treatment for single HCC ≤ 3 cm. The OS rate of patients suitable for surgical resection was similar to those reported in surgical series.

    This paper reports the first successful derivation and characterization of humpback whale fibroblast cell lines. Primary fibroblasts were isolated from the dermal connective tissue of skin biopsies, cultured at 37 °C and 5% CO2 in the standard mammalian medium DMEM/F12 supplemented with 10% fetal bovine serum (FBS). Of nine initial biopsies, two cell lines were established from two different animals and designated HuWa1 and HuWa2. The cells have a stable karyotype with 2n=44, which has commonly been observed in other baleen whale species. Cells were verified as being fibroblasts based on their spindle-shaped morphology, adherence to plastic and positive immunoreaction to vimentin. Population doubling time was determined to be ∼41 h and cells were successfully cryopreserved and thawed. To date, HuWa1 cells have been propagated 30 times. Cells proliferate at the tested temperatures, 30, 33.5 and 37 °C, but show the highest rate of proliferation at 37 °C. Short-term exposure to para,para'-dichlorodiphenyldichloroethylene (p,p'-DDE), a priority compound accumulating in southern hemisphere humpback whales, resulted in a concentration-dependent loss of cell viability. The effective concentration which caused a 50% reduction in HuWa1 cell viability (EC50 value) was approximately six times greater than the EC50 value for the same chemical measured with human dermal fibroblasts. HuWa1 exposed to a natural, p,p'-DDE-containing, chemical mixture extracted from whale blubber showed distinctively higher sensitivity than to p,p'-DDE alone. Thus, we provide the first cytotoxicological data for humpback whales and with establishment of the HuWa cell lines, a unique in vitro model for the study of the whales' sensitivity and cellular response to chemicals and other environmental stressors.

    Antiretroviral therapy (ART) is associated with a myriad of metabolic complications which are potential cardiovascular risk factors. Early detection of these risk factors could help in alleviating morbidity and mortality in human immunodeficiency virus (HIV) infected patients on ART. To study the prevalence of cardiovascular risk factors in patients on a combination of nucleoside reverse transcriptase inhibitors (NRTIs) and non-NRTIs (NNRTIs) - the standard combination first line ART regimen used in tertiary referral center. The prevalence of cardiovascular risk factors in HIV infected subjects with stage 1t disease on standard first line ART for at least 1 year, HIV infected subjects with stage 1 disease and not on ART and HIV negative subjects was assessed. The study was a cross-sectional study design. Basic demographic data was collected and patients were examined for anthropometric data and blood was collected for analysis of blood glucose, serum lipids, and fasting insulin levels. Chi-square test was used to calculate significance. Statistical Package for Social Sciences (SPSS) software version 16.0 was used for data analysis. The prevalence of hypercholesterolemia and hypertriglyceridemia was higher in the patients on ART when compared to patients not on ART (P<0.001). There was no difference in the prevalence of abnormal glycemic status, obesity, abdominal obesity, insulin resistance, and hyperinsulinemia between patients on ART and those not on ART. First line ART is associated with increased prevalence of dyslipidemia. Early detection and treatment of dyslipidemia should help in reducing the cardiovascular morbidity in patients on ART.

    The aim of this study was to assess the outcome of patients with aplastic anemia (AA), receiving rabbit anti-thymocyte globulin (Thymoglobulin, SANOFI) and cyclosporin, as first line treatment. Eligible were 955 patients with AA, treated first line with Thymoglobulin, between 2001 and 2008 (n = 492), or between 2009 and 2012 (n = 463). The median age of the patients was 21 years (range 1-84). Mortality within 90 days was 5.7% and 2.4%, respectively in the two time periods (P = .007).The actuarial 10-year survival for the entire population was 70%; transplant free survival was 64%. Predictors of survival in multivariate analysis, were severity of the disease, patients age and the interval between diagnosis and treatment. Survival was 87% vs 61% for responders at 6 months versus nonresponders (P < .0001). The 10-year survival of nonresponders at 6 months, undergoing a subsequent transplant (n = 110), was 64%, vs 60% for patient not transplantated (n = 266) (P = .1). The cumulative incidence of response was 37%, 52%, 65% respectively, at 90, 180, and 365 days. In multivariate analysis, negative predictors of response at 6 months, were older age, longer interval diagnosis treatment, and greater severity of the disease. In conclusion, early mortality is low after first line treatment of AA with Thymoglobulin, and has been further reduced after year 2008. Patients age, together with interval diagnosis-treament and severity of the disease, remain strong predictors of response and survival. © 2018 Wiley Periodicals, Inc.

    A phase II trial was performed to evaluate the efficacy and toxicity of vinorelbine (VNB) as first-line chemotherapy for metastatic breast carcinoma. Between August 1991 and February 1993, 45 patients with metastatic breast cancer were entered onto the study. Therapy consisted of VNB 30 mg/m2 diluted in 500 mL of normal saline administered as a 1-hour intravenous infusion. Injections were repeated weekly until evidence of progressive disease (PD) or severe toxicity developed. One patient was considered not assessable for response. An objective response (OR) was observed in 18 of 44 patients (41%; 95% confidence interval, 26% to 56%). Three patients (7%) had a complete response (CR) and 15 (34%) had a partial response (PR). The median time to treatment failure for the entire group was 6 months (range, 1 to 15), and the median duration of response was 9 months (range, 1 to 15). The median survival duration has not been reached yet. There were no treatment-related deaths. The dose-limiting toxicity was myelosuppression. Leukopenia occurred in 35 patients (78%) and was grade 3 or 4 in 16 (36%). Phlebitis was observed in 19 of 29 patients (66%) who did not have central implantable venous systems. Fifteen patients (33%) developed peripheral neurotoxicity. Myalgia occurred in 20 patients (44%). VNB is an active drug against metastatic breast cancer with moderate toxicity, which justifies further evaluation in association with other agents.

    Neuraminidase inhibitors are thought to be efficacious in reducing the time to alleviation of symptoms in outpatients with seasonal influenza. The objective of this study was to compare the short-term virological efficacy of oseltamivir-zanamivir combination versus each monotherapy plus placebo. We conducted a randomized placebo-controlled trial with 145 general practitioners throughout France during the 2008-2009 seasonal influenza epidemic. Patients, general practitioners, and outcome assessors were all blinded to treatment assignment. Adult outpatients presenting influenza-like illness for less than 36 hours and a positive influenza A rapid test diagnosis were randomized to oseltamivir 75 mg orally twice daily plus zanamivir 10 mg by inhalation twice daily (OZ), oseltamivir plus inhaled placebo (O), or zanamivir plus oral placebo (Z). Treatment efficacy was assessed virologically according to the proportion of patients with nasal influenza reverse transcription (RT)-PCR below 200 copies genome equivalent (cgeq)/µl at day 2 (primary outcome), and clinically to the time to alleviation of symptoms until day 14. Overall 541 patients (of the 900 planned) were included (OZ,  =192; O, n=176; Z, n=173), 49% male, mean age 39 years. In the intention-to-treat analysis conducted in the 447 patients with RT-PCR-confirmed influenza A, 46%, 59%, and 34% in OZ (n=157), O (n=141), and Z (n=149) arms had RT-PCR<200 cgeq/µl (-13.0%, 95% confidence interval [CI] -23.1 to -2.9, p=0.025; +12.3%, 95% CI 2.39-22.2, p=0.028 for OZ/O and OZ/Z comparisons). Mean day 0 to day 2 viral load decrease was 2.14, 2.49, and 1.68 log(10) cgeq/µl (p=0.060, p=0.016 for OZ/O and OZ/Z). Median time to alleviation of symptoms was 4.0, 3.0, and 4.0 days (+1.0, 95% CI 0.0-4.0, p=0.018; +0.0, 95% CI -3.0 to 3.0, p=0.960 for OZ/O and OZ/Z). Four severe adverse events were observed.

The 73 patients with ALK-positive advanced NSCLC were divided into three groups based on the first-line treatment: first-line crizotinib group (1-CRZ group, n = 32); first-line platinum-based pemetrexed treatment group (1-PP group, n = 28), and first-line chemotherapy platinum-based non-pemetrexed group (N1-PP, n = 12). Sixty eight of the 73 patients received crizotinib treatment and followed up in our hospital. Differences in the objective response rate (ORR), disease control rate (DCR) and progression-free survival (PFS) were compared in the different groups. The clinical factors were evaluated to predict the efficacy of crizotinib by the Kaplan-Meier survival analysis and Cox proportional hazards model. The PFS, ORR, DCR were 16.1 months, 78.1% (25/32) and 100% (32/32) in the 1-CRZ group; were 6.0 months, 17.9% (5/28) and 57.2% (16/28) in the 1-PP group; and were 2.9 months, 15.4% (2/13) and 46.2% (6/13) in the N1-PP group. The PFS of the 1-CRZ group was significantly longer than that of the 1-PP group (P < 0.001) and the N1-PP group (P < 0.001). The ORR and DCR of the 1-CRZ group was significantly greater than that of the 1-PP group and the N1-PP group (all the P < 0.001). Higher Eastern Cooperative Oncology Group (ECOG) performance status score (> = 2) (HR 2.345, 95% CI 1.137-4.834, P = 0.021) and patients received crizotinib after N1-PP chemotherapy (HR 2.345, 95% CI 1.137-4.834, P = 0.021) were two factors associated with shorter PFS after crizotinib treatment. In patients with ALK-positive NSCLC who did not receive previous treatment, crizotinib was superior to standard chemotherapy for the longer PFS and greater

    HCV kinetic analysis and modeling during antiviral therapy have not been performed in decompensated cirrhotic patients awaiting liver transplantation. Here, viral and host parameters were compared in patients treated with daily intravenous silibinin (SIL) monotherapy for 7 days according to the severity of their liver disease. Data were obtained from 25 patients, 12 non-cirrhotic, 8 with compensated cirrhosis and 5 with decompensated cirrhosis. The standard-biphasic model with time-varying SIL effectiveness (from 0 to ε max) was fit to viral kinetic data. Our results show that baseline viral load and age were significantly associated with the severity of liver disease (p<0.0001).more » A biphasic viral decline was observed in most patients with a higher first phase decline patients with less severe liver disease. The maximal effectiveness, ε max, was significantly (p≤0.032) associated with increasing severity of liver disease (ε max[s.e.]=0.86[0.05], ε max=0.69[0.06] and ε max=0.59[0.1]). The 2nd phase decline slope was not significantly different among groups (mean 1.88±0.15 log 10IU/ml/wk, p=0.75) as was the rate of change of SIL effectiveness (k=2.12/day[standard error, SE=0.18/day]). HCV-infected cell loss rate (δ[SE]=0.62/day[0.05/day]) was high and similar among groups. We conclude that the high loss rate of HCV-infected cells suggests that sufficient dose and duration of SIL might achieve viral suppression in advanced liver disease.« less

    Antiretroviral therapy (ART) has evolved rapidly since its beginnings. This analysis describes trends in first-line ART use in Asia and their impact on treatment outcomes. Patients in the TREAT Asia HIV Observational Database receiving first-line ART for ≥ 6 months were included. Predictors of treatment failure and treatment modification were assessed. Data from 4662 eligible patients was analysed. Patients started ART in 2003-2006 (n = 1419), 2007-2010 (n = 2690) and 2011-2013 (n = 553). During the observation period, tenofovir, zidovudine and abacavir use largely replaced stavudine. Stavudine was prescribed to 5.8% of ART starters in 2012/13. Efavirenz use increased at the expense of nevirapine, although both continue to be used extensively (47.5% and 34.5% of patients in 2012/13, respectively). Protease inhibitor use dropped after 2004. The rate of treatment failure or modification declined over time (22.1 [95%CI 20.7-23.5] events per 100 patient/years in 2003-2006, 15.8 [14.9-16.8] in 2007-2010, and 11.6 [9.4-14.2] in 2011-2013). Adjustment for ART regimen had little impact on the temporal decline in treatment failure rates but substantially attenuated the temporal decline in rates of modification due to adverse event. In the final multivariate model, treatment modification due to adverse event was significantly predicted by earlier period of ART initiation (hazard ratio 0.52 [95%CI 0.33-0.81], p = 0.004 for 2011-2013 versus 2003-2006), older age (1.56 [1.19-2.04], p = 0.001 for ≥ 50 years versus <30 years), female sex (1.29 [1.11-1.50], p = 0.001 versus male), positive hepatitis C status (1.33 [1.06-1.66], p = 0.013 versus negative), and ART regimen (11.36 [6.28-20.54], p<0.001 for stavudine-based regimens versus tenofovir-based). The observed trends in first-line ART use in Asia reflect changes in drug availability, global treatment recommendations and prescriber preferences over the past decade. These changes have contributed to a declining rate of

    Metformin is the first-line oral therapy for type 2 diabetes with proven benefits against cardiovascular risk. Recent evidence suggested that acarbose might be similar to metformin in glucose-lowering efficacy and cardiovascular risk reduction. Therefore, international guidelines have suggested the use of acarbose as alternative first-line antidiabetic therapy. To compare the cardiovascular outcomes in the first-line users of acarbose vs metformin. DESIGN, SETTING, PATIENTS, AND OUTCOME MEASURES: A nationwide cohort study was conducted by analyzing the Taiwan National Health Insurance (NHI) Database. A total of 17,366 acarbose initiators and 230,023 metformin initiators were identified between January 1, 2009 and December 31, 2010. The primary outcome is hospitalization due to any cardiovascular events, including acute myocardial infarction, congestive heart failure, and ischemic stroke. The propensity score method was used to adjust for baseline differences between the two groups. Patients were followed from drug initiation to the earliest of outcome occurrence, death or disenrollment from NHI, or study termination. In intention-to-treat analyses, acarbose was associated with a higher risk of any cardiovascular event (adjusted hazard ratio [HR]: 1.05; 95% confidence interval [CI], 1.01-1.09), heart failure (HR, 1.08; 95% CI, 1.00-1.16), and ischemic stroke (HR, 1.05, 95% CI, 1.00-1.10) than metformin. No significant difference in risk was found in subgroups of patients with or without underlying hypertension, ischemic heart disease, or cerebrovascular disease. Similar results were found in auxiliary as-treated analyses or analyses stratified by propensity score quintiles. Our data do not support that acarbose has a cardio-protective effect similar to metformin as a first-line antidiabetic agent.

    Background Medicines to control hypertension, a leading cause of morbidity and mortality, are a major component of health expenditures in the Philippines. This study aims to review economic studies for first line anti-hypertensive medical treatment without co-morbidities; and discuss practical, informational and policy implications on the use of economic evaluation in the Philippines. Methods A systematic literature review was performed using the following databases: MEDLINE, EMBASE, BIOSIS, PubMed, The Cochrane Library, Health Economics Evaluations Database (HEED) and the Centre for Reviews and Dissemination – NHS NICE. Six existing economic analytical frameworks were reviewed and one framework for critical appraisal was developed. Results Out of 1336 searched articles, 12 fulfilled the inclusion criteria. The studies were summarized according to their background characteristics (year, journal, intervention and comparators, objective/study question, target audience, economic study type, study population, setting and country and source of funding/conflict of interest) and technical characteristics (perspective, time horizon, methodology/modeling, search strategy for parameters, costs, effectiveness measures, discounting, assumptions and biases, results, cost-effectiveness ratio, endpoints, sensitivity analysis, generalizability, strengths and limitations, conclusions, implications and feasibility and recommendations). The studies represented different countries, perspectives and stakeholders. Conclusions Diuretics were the most cost-effective drug class for first-line treatment of hypertension without co-morbidities. Although the Philippine Health Insurance Corporation may apply the recommendations given in previous studies (i.e. to subsidize diuretics, ACE inhibitors and calcium channel blockers), it is uncertain how much public funding is justified. There is an information gap on clinical data (transition probabilities, relative risks and risk reduction) and

    Bruton's tyrosine kinase (BTK) is a key regulator of the B-cell receptor signaling pathway, and aberrant B-cell receptor (BCR) signaling has been implicated in the survival of malignant B-cells. However, responses of the diffuse large B-cell lymphoma (DLBCL) to inhibitors of BTK (BTKi) are infrequent, highlighting the need to identify mechanisms of resistance to BTKi as well as predictive biomarkers. We investigated the response to the selective BTKi, tirabrutinib, in a panel of 64 hematopoietic cell lines. Notably, only six cell lines were found to be sensitive. Although activated B-cell type DLBCL cells were most sensitive amongst all cell types studied, sensitivity to BTKi did not correlate with the presence of activating mutations in the BCR pathway. To improve efficacy of tirabrutinib, we investigated combination strategies with 43 drugs inhibiting 34 targets in six DLBCL cell lines. Based on the results, an activated B-cell-like (ABC)-DLBCL cell line, TMD8, was the most sensitive cell line to those combinations, as well as tirabrutinib monotherapy. Furthermore, tirabrutinib in combination with idelalisib, palbociclib, or trametinib was more effective in TMD8 with acquired resistance to tirabrutinib than in the parental cells. These targeted agents might be usefully combined with tirabrutinib in the treatment of ABC-DLBCL.

  14. Mean CD4 cell count changes in patients failing a first-line antiretroviral therapy in resource-limited settings

    Background Changes in CD4 cell counts are poorly documented in individuals with low or moderate-level viremia while on antiretroviral treatment (ART) in resource-limited settings. We assessed the impact of on-going HIV-RNA replication on CD4 cell count slopes in patients treated with a first-line combination ART. Method Naïve patients on a first-line ART regimen with at least two measures of HIV-RNA available after ART initiation were included in the study. The relationships between mean CD4 cell count change and HIV-RNA at 6 and 12 months after ART initiation (M6 and M12) were assessed by linear mixed models adjusted for gender, age, clinical stage and year of starting ART. Results 3,338 patients were included (14 cohorts, 64% female) and the group had the following characteristics: a median follow-up time of 1.6 years, a median age of 34 years, and a median CD4 cell count at ART initiation of 107 cells/μL. All patients with suppressed HIV-RNA at M12 had a continuous increase in CD4 cell count up to 18 months after treatment initiation. By contrast, any degree of HIV-RNA replication both at M6 and M12 was associated with a flat or a decreasing CD4 cell count slope. Multivariable analysis using HIV-RNA thresholds of 10,000 and 5,000 copies confirmed the significant effect of HIV-RNA on CD4 cell counts both at M6 and M12. Conclusion In routinely monitored patients on an NNRTI-based first-line ART, on-going low-level HIV-RNA replication was associated with a poor immune outcome in patients who had detectable levels of the virus after one year of ART.

    With the advent of targeted therapies, many treatment options in the first-line setting of metastatic clear cell renal cell carcinoma (mccRCC) have emerged. Guidelines and randomized trial reports usually do not elucidate the decision criteria for the different treatment options. In order to extract the decision criteria for the optimal therapy for patients, we performed an analysis of treatment algorithms from experts in the field. Treatment algorithms for the treatment of mccRCC from experts of 11 institutions were obtained, and decision trees were deduced. Treatment options were identified and a list of unified decision criteria determined. The final decision trees were analyzed with a methodology based on diagnostic nodes, which allows for an automated cross-comparison of decision trees. The most common treatment recommendations were determined, and areas of discordance were identified. The analysis revealed heterogeneity in most clinical scenarios. The recommendations selected for first-line treatment of mccRCC included sunitinib, pazopanib, temsirolimus, interferon-α combined with bevacizumab, high-dose interleukin-2, sorafenib, axitinib, everolimus, and best supportive care. The criteria relevant for treatment decisions were performance status, Memorial Sloan Kettering Cancer Center risk group, only or mainly lung metastases, cardiac insufficiency, hepatic insufficiency, age, and "zugzwang" (composite of multiple, related criteria). In the present study, we used diagnostic nodes to compare treatment algorithms in the first-line treatment of mccRCC. The results illustrate the heterogeneity of the decision criteria and treatment strategies for mccRCC and how available data are interpreted and implemented differently among experts. The data provided in the present report should not be considered to serve as treatment recommendations for the management of treatment-naïve patients with multiple metastases from metastatic clear cell renal cell carcinoma outside

    Context. The mass-loss mechanism in normal K-M giant stars with small variability amplitudes is not yet understood, although the majority among red giant stars are precisely of this type. Aims: We present high-spatial and high-spectral resolution observations of the M7 giant BK Vir with AMBER at the Very Large Telescope Interferometer (VLTI). Our aim is to probe the physical properties of the outer atmosphere by spatially resolving the star in the individual CO first overtone lines. Methods: BK Vir was observed between 2.26 and 2.31 μm using the 16-32-48 m telescope configuration with an angular resolution of 9.8 mas and a spectral resolution of 12 000. Results: The uniform-disk diameters observed in the CO first overtone lines are 12 - 31% larger than those measured in the continuum. We also detected asymmetry in the CO line-forming region, which manifests itself as non-zero/non-π differential and closure phases. The data taken 1.5 months apart show possible time variation on a spatial scale of 30 mas (corresponding to 3 × stellar diameter) at the CO band head. Comparison of the observed data with the MARCS photospheric model shows that whereas the observed CO line spectrum can be satisfactorily reproduced by the model, the angular sizes observed in the CO lines are much larger than predicted by the model. Our model with two additional CO layers above the MARCS photosphere reproduces the observed spectrum and interferometric data in the CO lines simultaneously. This model suggests that the inner CO layer at ~1.2 R⋆ is very dense and warm with a CO column density of ~1022 cm-2 and temperatures of 1900 - 2100 K, while the outer CO layer at 2.5-3.0 R⋆ is characterized by column densities of 1019-1020 cm-2 and temperatures of 1500 - 2100 K. Conclusions: Our AMBER observations of BK Vir have spatially resolved the extended molecular outer atmosphere of a normal M giant in the individual CO lines for the first time. The temperatures derived for the CO layers are

    To provide a clinically-focused review of the biological treatment of treatment-resistant obsessive compulsive disorder (OCD). There is a paucity of research on how to manage OCD patients who fail to respond adequately to first line therapies. High-dose selective serotonin reuptake inhibitors (SSRIs) and clomipramine have good evidence-based data. Combinations of SSRIs have little support in clinical trials, but the combination of SSRIs and clomipramine can be helpful: careful clinical and cardiac monitoring is required. Certain adjunctive antipsychotics have a reasonable evidence base in OCD, but their use also needs to be weighed against the potential side effect burden. In patients with substantial generalised anxiety symptoms, clonazepam is worth considering. Of the other augmenting strategies, memantine and ondansetron appear useful in some cases, and are well tolerated. Topiramate might ameliorate compulsions to some degree, but it is less well tolerated. If all these strategies, along with expert psychological therapy, fail, careful consideration should be given to deep brain stimulation (DBS), which has an emerging evidence base and which can result in dramatic benefits for some individuals. For some patients, gamma radiosurgery might also still have a place. © The Royal Australian and New Zealand College of Psychiatrists 2015.

    Schizophrenia is accompanied by impaired cortical inhibition, as measured by several markers including the cortical silent period (CSP). It is thought that CSP measures gamma-aminobutyric acid receptors B (GABA B ) mediated inhibitory activity. But the mutual roles of schizophrenia as a disease and the drugs used for the treatment of psychosis on GABA mediated neurotransmission are not clear. We recruited 13 drug-naive patients with first-episode schizophrenia. We used transcranial magnetic stimulation to assess CSP prior to initiating risperidone monotherapy and again four weeks later. At the same time, we rated the severity of psychopathology using the Positive and Negative Syndrome Scale (PANSS). We obtained data from 12 patients who showed a significant increase in CSP, from 134.20±41.81 ms to 162.95±61.98 ms ( p=0.041; Cohen's d=0.544). After the treatment, the PANSS total score was significantly lower, as were the individual subscores ( p<0.05). However, no correlation was found between ΔCSP and ΔPANSS. Our study in patients with first-episode schizophrenia demonstrated an association between risperidone monotherapy and an increase in GABA B mediated inhibitory neurotransmission.

    Previous studies have shown a positive effect of zinc as an adjunctive therapy on reducing depressive symptoms. However, to our knowledge, no study has examined the effect of zinc monotherapy on mood. The aim of the present study was to determine the effects of zinc monotherapy on depressive symptoms and serum brain-derived neurotrophic factor (BDNF) levels in overweight or obese subjects. Fifty overweight or obese subjects were randomly assigned into two groups and received either 30 mg zinc or placebo daily for 12 weeks. At baseline and post-intervention, depression severity was assessed using Beck depression inventory II (BDI II), and serum BDNF and zinc levels were determined by enzyme-linked immunosorbent assay and atomic absorption spectrophotometry, respectively. The trial was completed with 46 subjects. After a 12-week supplementation, serum zinc and BDNF levels increased significantly in the zinc-supplemented group compared with the placebo group. BDI scores declined in both the groups at the end of the study, but reduction in the zinc-supplemented group was significantly higher than the placebo group. More analysis revealed that following supplementation, BDI scores decreased in subgroup of subjects with depressive symptoms (BDI ≥ 10) (n = 30), but did not change in the subgroup of non-depressed subjects (BDI < 10) (n = 16). Moreover, a significant inverse correlation was observed between serum BDNF levels and depression severity in all participants. Interestingly, a significant positive correlation was found between serum BDNF and zinc levels at baseline. Zinc monotherapy improves mood in overweight or obese subjects most likely through increasing BDNF levels.

    Only limited pedagogical use has been made of information and communications technology (ICT) in nursing education in Norway. In this study the use of ICT was linked to assignments in the first year undergraduate nursing program and included four on-line discussions. There is evidence to suggest that on-line discussions can enhance the learning environment. The students' experiences of the on-line discussions are compared to those of the students participating in traditional group discussions. The results show little difference between the two groups' opinions of the discussions' fruitfulness and the ease in which they expressed their feelings, thoughts and ideas. However, there is a marked difference between the two groups regarding their experience of how the discussions affected the amount of contact between group members outside the discussions. Possible reasons for these findings are discussed.

    In this paper, we focus on UAV-borne laser scanning with the objective of densely sampling object surfaces in the local surrounding of the UAV. In this regard, using a line scanner which scans along the vertical direction and perpendicular to the flight direction results in a point cloud with low point density if the UAV moves fast. Using a line scanner which scans along the horizontal direction only delivers data corresponding to the altitude of the UAV and thus a low scene coverage. For these reasons, we present a concept and a system for UAV-borne laser scanning using multiple line scanners. Our system consists of a quadcopter equipped with horizontally and vertically oriented line scanners. We demonstrate the capabilities of our system by presenting first results obtained for a flight within an outdoor scene. Thereby, we use a downsampling of the original point cloud and different neighborhood types to extract fundamental geometric features which in turn can be used for scene interpretation with respect to linear, planar or volumetric structures.

    To determine activity and safety of capecitabine at a moderate dose of 2000 mg/m(2) as first-line therapy for metastatic breast cancer. In this prospective phase II trial, patients with HER2-negative metastatic breast cancer received first-line capecitabine 2000 mg/m(2) on days 1-14 every 3 weeks. The primary aim was to exclude a time to progression (TTP) <6 months. Secondary end-points were overall response rate, overall survival (OS), toxicity and quality of life. Median age of the 161 included patients was 65 years. Median TTP and OS were 7.3 months [95% (confidence interval) CI: 6.2-8.4] and 17.1 months (95% CI: 14.0-20.3), respectively. An overall response rate of 26.1%, including 13 complete remissions was observed. Patients developing grade I-III hand-foot syndrome had a significantly longer TTP and OS and patients >65 years also achieved a significantly longer TTP. Haematological grade I-IV toxicities were leucopenia (64.0%), anaemia (50.9%) and thrombocytopenia (28.0%). Relevant non-haematological toxicities were hand-food-syndrome (37.3%), fatigue (34.2%), nausea (29.8%) and diarrhoea (20.5%). Quality of life assessment revealed an improved emotional function, but worsening of nausea and vomiting from cycle 1-10. Capecitabine at a dose of 2000 mg/m(2) is active and safe as first-line treatment of patients with metastatic breast cancer. Copyright © 2010 Elsevier Ltd. All rights reserved.

    BACKGROUND In Poland, natalizumab or fingolimod treatment can be delivered as a second-line therapy to those patients with relapsing-remitting multiple sclerosis (RRMS) who demonstrated no response to interferon or glatiramer acetate treatment for a minimum of one year. MATERIAL AND METHODS Analysis covered 44 RRMS patients switched from first- to second-line therapy. The annualized relapse rate, disability progression (assessed with Expanded Disability Status Scale, EDSS) and MRI results (new or enlarged T2 lesions and new Gd-positive lesions) before and after switching were compared. The occurrence of adverse events was also assessed. RESULTS The annualized relapse rate for second-line therapy was significantly lower than for first-line therapy (0.35±0.74 vs. 2.13±0.87, p=0.00005). Median of EDSS progression with first-line therapy was significantly higher than that with natalizumab or fingolimod treatment (p=0.00002). The mean number of new or enlarged T2 and Gd+ lesions in MRI after one-year second-line treatment was significantly lower in comparison to lesions in MRI performed at the end of the first-line therapy (for T2: 0.61 vs. 4.56, p=0.0004; for Gd+: 0.13 vs. 1.98, p=0.0009). No significant differences in the clinical data, MRI results, and side effects between fingolimod and natalizumab patients have been observed. CONCLUSIONS Treatment with natalizumab or fingolimod as a second-line therapy in RRMS patients is safe and effective. Less restrictive criteria for switching should be considered.

  4. Experience with ibrutinib for first-line use in patients with chronic lymphocytic leukemia.

    Ibrutinib is the first in-class, orally administered, Bruton's tyrosine kinase (BTK) inhibitor that abrogates the critical signaling downstream of the B-cell receptor (BCR). This signaling is required for B-cell survival, proliferation and interaction with the microenvironment. Ibrutinib proved active in preclinical models of lymphoproliferative diseases and achieved impressive response rates in heavily pretreated relapsed and refractory (R/R) patients with chronic lymphocytic leukemia (CLL). Ibrutinib prolonged survival compared to standard therapy and mitigated the effect of most poor prognostic factors in CLL, thus becoming the main therapeutic option in high-risk populations. Moreover, compared with standard chemoimmunotherapy (CIT) for adults, ibrutinib causes fewer cytopenias and infections, while having its own unique toxicity profile. Its efficacy in relapsed patients as well as its tolerability have led to its increased use in previously untreated patients, especially in those with poor prognostic markers and/or the elderly. This review elaborates on ibrutinib's unique toxicity profile and the mechanisms of acquired resistance leading to progression on ibrutinib, since both are critical for understanding the obstacles to its first-line use. We will further evaluate the data from ongoing clinical trials in this setting and explore future options for combination therapy.

    Patients with cancer suffer a wide range of physical symptoms coupled with psychological stress. Moreover, cancer chemotherapy induces immunosuppression and consequently causes respiratory infections. Massage therapy has been reported to reduce symptoms in cancer patients via an increase in psychosocial relaxation and to enhance and/or improve immune function. In the present study, we determined whether leg massage could induce psychosocial relaxation and activate the first line of the host defense system. To assess effects of rest and leg massage, 15 healthy volunteers rested on a bed for 20 min on the first day, and 3 days later the subjects received a standardized massage of the legs for 20 min with nonaromatic oil. Twenty-nine cancer patients also received the same standardized massage of the legs. Anxiety/stress was assessed before and just after the rest or the massage using the State-Trait Anxiety Inventory (STAI-s) and visual analogue scale (VAS). To evaluate oral immune function, salivary chromogranin A (CgA) and secretory immunoglobulin A (sIgA) levels were measured. In healthy volunteers, rest significantly reduced VAS by 34% and increased sIgA by 61%. In contrast, leg massage significantly reduced both STAI-s and VAS by 24% and 63%, and increased both sIgA and CgA by 104% and 90%, respectively. In cancer patients, leg massage significantly decreased both STAI-s and VAS by 16% and 38%, and increased both salivary CgA and sIgA by 33% and 35%, respectively. Leg massage may promote psychosocial relaxation and reinforce a first-line host defense with an increase in secretion of antimicrobial peptides.

    Enterococcus faecium that harbor LiaFSR substitutions but are phenotypically susceptible to daptomycin (DAP) by current breakpoints are problematic since predisposition to resistance may lead to therapeutic failure. Using a simulated endocardial vegetation (SEV) PK/PD model, we investigated DAP regimens (6, 8 and 10 mg/kg/day) as monotherapy and in combination with ampicillin (AMP), ceftaroline (CPT) or ertapenem (ERT) against E. faecium HOU503, a DAP-susceptible strain that harbors common LiaS and LiaR substitutions found in clinical isolates (T120S and W73C, respectively). Of interest, the efficacy of DAP monotherapy, at any dose regimen, was dependent on the size of the inoculum. At an inoculum of ∼10 9 CFU/g, DAP doses of 6-8 mg/kg/d were not effective and led to significant regrowth with emergence of resistant derivatives. In contrast, at an inoculum of ∼10 7 , marked reductions in bacterial counts were observed with DAP 6 mg/kg/d with no resistance. The inoculum effect was confirmed in a rat model using humanized DAP exposures. Combinations of DAP with AMP, CPT or ERT demonstrated enhanced eradication and reduced potential for resistance allowing for de-escalation of the DAP dose. Persistence of the LiaRS substitutions were identified in DAP-resistant isolates recovered from the SEV model and in DAP-resistant derivatives of an initially DAP-susceptible clinical isolate of E. faecium (HOU668) harboring LiaSR substitutions and recovered from a patient with a recurrent bloodstream infection. Our results provide novel data for the use of DAP monotherapy and combinations for recalcitrant E. faecium infections and paves the way for testing these approaches in humans.

    Tumor heterogeneity may give rise to differential responses to chemotherapy drugs. Therefore, unraveling tumor heterogeneity has an implication for biomarker discovery and cancer therapeutics. To test this phenomenon, we investigated the differential responses of three secondary colorectal cancer cell lines of different origins (HCT116, HT29, and SW620 cells) and four novel primary cell lines obtained from different colorectal cancer patients to 5-fluorouracil (5-FU) and oxaliplatin (L-OHP) and explored the differences in gene expression among the primary cell lines in response to exposure to cytotoxic drugs. Cells were exposed to different doses of 5-FU and L-OHP separately or in combinations of equitoxic drug or equimolar drug ratios (median effect of Chou-Talalay principle). Cell viability was assessed using MTT assay and the respective IC 50 values were determined. Changes in gene expression in primary cell lines after exposure to the same drug doses were compared using real-time PCR array. The sensitivities (IC 50 ) of different cell lines, both secondary and primary, to 5-FU and L-OHP were significantly different, whether in monotherapy or combined treatment. Primary cell lines needed higher doses to reach IC 50 . There were variations in gene expression among the primary cell lines of different chemosensitivities to the challenge of the same combined dose of 5-FU and L-OHP. The results confirm the heterogeneous nature of colorectal cancer cells from different patient tumors. Studies using primary cancer cells established from patient's tumors rather than secondary cell lines will more closely reflect the actual character of the disease.

    The randomised phase III TANIA trial demonstrated that continuing bevacizumab with second-line chemotherapy for locally recurrent/metastatic breast cancer (LR/mBC) after progression on first-line bevacizumab-containing therapy significantly improved progression-free survival (PFS) compared with chemotherapy alone [hazard ratio (HR) = 0.75, 95% confidence interval (CI) 0.61-0.93]. We report final results from the TANIA trial, including overall survival (OS) and health-related quality of life (HRQoL). Patients with HER2-negative LR/mBC that had progressed on or after first-line bevacizumab plus chemotherapy were randomised to receive standard second-line chemotherapy either alone or with bevacizumab. At second progression, patients initially randomised to bevacizumab continued bevacizumab with their third-line chemotherapy, but those randomised to chemotherapy alone were not allowed to cross over to receive third-line bevacizumab. The primary end point was second-line PFS; secondary end points included third-line PFS, combined second- and third-line PFS, OS, HRQoL and safety. Of the 494 patients randomised, 483 received second-line therapy; 234 patients (47% of the randomised population) continued to third-line study treatment. The median duration of follow-up at the final analysis was 32.1 months in the chemotherapy-alone arm and 30.9 months in the bevacizumab plus chemotherapy arm. There was no statistically significant difference between treatment arms in third-line PFS (HR = 0.79, 95% CI 0.59-1.06), combined second- and third-line PFS (HR = 0.85, 95% CI 0.68-1.05) or OS (HR = 0.96, 95% CI 0.76-1.21). Third-line safety results showed increased incidences of proteinuria and hypertension with bevacizumab, consistent with safety results for the second-line treatment phase. No differences in HRQoL were detected. In this trial, continuing bevacizumab beyond first and second progression of LR/mBC improved second-line PFS, but no improvement in longer term efficacy was

    Bruton’s tyrosine kinase (BTK) is a key regulator of the B-cell receptor signaling pathway, and aberrant B-cell receptor (BCR) signaling has been implicated in the survival of malignant B-cells. However, responses of the diffuse large B-cell lymphoma (DLBCL) to inhibitors of BTK (BTKi) are infrequent, highlighting the need to identify mechanisms of resistance to BTKi as well as predictive biomarkers. We investigated the response to the selective BTKi, tirabrutinib, in a panel of 64 hematopoietic cell lines. Notably, only six cell lines were found to be sensitive. Although activated B-cell type DLBCL cells were most sensitive amongst all cell types studied, sensitivity to BTKi did not correlate with the presence of activating mutations in the BCR pathway. To improve efficacy of tirabrutinib, we investigated combination strategies with 43 drugs inhibiting 34 targets in six DLBCL cell lines. Based on the results, an activated B-cell-like (ABC)-DLBCL cell line, TMD8, was the most sensitive cell line to those combinations, as well as tirabrutinib monotherapy. Furthermore, tirabrutinib in combination with idelalisib, palbociclib, or trametinib was more effective in TMD8 with acquired resistance to tirabrutinib than in the parental cells. These targeted agents might be usefully combined with tirabrutinib in the treatment of ABC-DLBCL. PMID:29690649

    Malignant melanoma is a highly aggressive form of skin cancer with a high mortality rate if not discovered in early stages. Although a limited number of treatment options for melanoma currently exist, patients with a more aggressive form of this cancer frequently decline treatment. DM-1 is a sodium phenolate and curcumin analog with proven anticancer, anti-proliferative and anti-metastatic properties. In this paper, the DM-1 compound showed in vivo antitumor activity alone or in combination with chemotherapeutic DTIC in B16F10 melanoma-bearing mice. Beneficial effects such as melanoma tumor burden reduction with pyknotic nuclei, decreased nuclei/cytoplasmic ratio and nuclear degradation occurred after DM-1 treatment. No toxicological changes were observed in the liver, kidneys, spleen and lungs after DM-1 monotherapy or DTIC combined therapy. DTIC+DM-1 treatment induced the recovery of anemia arising from melanoma and immunomodulation. Both DM-1 treatment alone and in combination with DTIC induced apoptosis with the cleavage of caspase-3, -8 and -9. Furthermore, melanoma tumors treated with DM-1 showed a preferential apoptotic intrinsic pathway by decreasing Bcl-2/Bax ratio. Considering the chemoresistance exhibited by melanoma towards conventional chemotherapy drugs, DM-1 compound in monotherapy or in combination therapy provides a promising improvement in melanoma treatment with a reduction of side effects.

    Malignant melanoma is a highly aggressive form of skin cancer with a high mortality rate if not discovered in early stages. Although a limited number of treatment options for melanoma currently exist, patients with a more aggressive form of this cancer frequently decline treatment. DM-1 is a sodium phenolate and curcumin analog with proven anticancer, anti-proliferative and anti-metastatic properties. In this paper, the DM-1 compound showed in vivo antitumor activity alone or in combination with chemotherapeutic DTIC in B16F10 melanoma-bearing mice. Beneficial effects such as melanoma tumor burden reduction with pyknotic nuclei, decreased nuclei/cytoplasmic ratio and nuclear degradation occurred after DM-1 treatment. No toxicological changes were observed in the liver, kidneys, spleen and lungs after DM-1 monotherapy or DTIC combined therapy. DTIC+DM-1 treatment induced the recovery of anemia arising from melanoma and immunomodulation. Both DM-1 treatment alone and in combination with DTIC induced apoptosis with the cleavage of caspase-3, -8 and -9.

    At the present time, there are no proven beneficial effects of chemotherapy (CT) for the treatment of pure low-grade astrocytomas. Brain radiotherapy (RT) still remains the standard treatment in order to reduce or delay tumor progression or symptoms, despite possible long-term neurologic complications. We report 10 patients, with histologically proven pure low-grade fibrillary astrocytomas, to which we administered a first-line nitrosourea-based CT. All patients were symptomatic with pharmaco-resistant epilepsy or neurologic symptoms, and had been rejected for neurosurgical resection. All patients with epilepsy had a clinical improvement with reduction in seizure frequency and 60% became seizure-free. CT was well tolerated; all patients developed myelosuppression with 40% of grade III/IV hematotoxicity. Seven were alive at the time of writing with a mean follow-up of 6.5 years (3.5-12) from first recorded symptoms. The three deceased patients died 7.5, 7.5, and 8.5 years from first symptoms. These results demonstrate that some patients with symptomatic non-resectable fibrillary low-grade astrocytomas can be treated with up-front CT to improve their neurologic status. This report suggests that benefits of CT on symptoms, survival, and quality of life should be prospectively compared with RT.

    Clinical monitoring of pediatric HIV treatment remains a major challenge in settings where drug resistance genotyping is not routinely available. As a result, our understanding of drug resistance, and its impact on subsequent therapeutic regimens available in these settings, remains limited. We investigate the prevalence and correlates of HIV-1 drug resistance among 94 participants of the Ethiopia Pediatric HIV Cohort failing first-line combination antiretroviral therapy (cART) using dried blood spot-based genotyping. Overall, 81% (73/90) of successfully genotyped participants harbored resistance mutations, including 69% (62/90) who harbored resistance to both Nucleoside Reverse Transcriptase Inhibitors (NRTIs) and Non-nucleoside Reverse Transcriptase Inhibitors (NNRTIs). Strikingly, 42% of resistant participants harbored resistance to all four NRTIs recommended for second-line use in this setting, meaning that there are effectively no remaining cART options for these children. Longer cART duration and prior regimen changes were significantly associated with detection of drug resistance mutations. Replicate genotyping increased the breadth of drug resistance detected in 34% of cases, and thus is recommended for consideration when typing from blood spots. Implementation of timely drug resistance testing and access to newer antiretrovirals and drug classes are urgently needed to guide clinical decision-making and improve outcomes for HIV-infected children on first-line cART in Ethiopia.

    Neratinib (Nerlynx™) is an oral, irreversible inhibitor of the human epidermal growth factor receptors HER1 (EGFR), HER2 and HER4. The drug originally arose from research by Wyeth (now Pfizer) and is now being developed by Puma Biotechnology primarily for the treatment of HER2-positive (HER+) breast cancer. Neratinib is approved in the USA for the extended adjuvant treatment of patients with HER2+ early-stage breast cancer who have been previously treated with a trastuzumab-based adjuvant regimen, and is in the preregistration phase for this indication in the EU. Neratinib, as monotherapy and/or combination therapy, is also in phase 3 development for metastatic breast cancer and in phase 1/2 development for advanced breast cancer and other solid tumours, including non-small cell lung cancer, colorectal cancer and glioblastoma. This article summarizes the milestones in the development of neratinib leading to this first approval for breast cancer.

    Lipoprotein (a) [Lp(a)] is an independent risk factor for cardiovascular disease. There are currently limited therapeutic options to lower Lp(a) levels. L-Carnitine has been reported to reduce Lp(a) levels. The aim of this study was to compare the effect of L-carnitine/simvastatin co-administration with that of simvastatin monotherapy on Lp(a) levels in subjects with mixed hyperlipidemia and elevated Lp(a) concentration. Subjects with levels of low-density lipoprotein cholesterol (LDL-C) >160 mg/dL, triacylglycerol (TAG) >150 mg/dL and Lp(a) >20 mg/dL were included in this study. Subjects were randomly allocated to receive L-carnitine 2 g/day plus simvastatin 20 mg/day (N = 29) or placebo plus simvastatin 20 mg/day (N = 29) for a total of 12 weeks. Lp(a) was significantly reduced in the L-carnitine/simvastatin group [-19.4%, from 52 (20-171) to 42 (15-102) mg/dL; p = 0.01], but not in the placebo/simvastatin group [-6.7%, from 56 (26-108) to 52 (27-93) mg/dL, p = NS versus baseline and p = 0.016 for the comparison between groups]. Similar significant reductions in total cholesterol, LDL-C, apolipoprotein (apo) B and TAG were observed in both groups. Co-administration of L-carnitine with simvastatin was associated with a significant, albeit modest, reduction in Lp(a) compared with simvastatin monotherapy in subjects with mixed hyperlipidemia and elevated baseline Lp(a) levels.

    As the first epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) in China, icotinib shows promising anticancer activity in vitro and vivo. The phase III clinical study (ICOGEN) showed that icotinib has a good efficacy and tolerability in Chinese patients with advanced non-small cell lung cancer (NSCLC) compared with gefitinib. This retrospective study aims to evaluate the efficacy and tolerability of icotinib monotherapy for advanced NSCLC patients with EGFR mutation and wild-type patients in our hospital. Patients with advanced NSCLC who were treated with icotinib in Zhejiang Cancer Hospital were retrospectively analyzed from August, 2011 to August, 2012. Survival was estimated using Kaplan-Meier analysis and Log-rank tests. The clinical data of 49 patients (13 with wild-type and 36 with EGFR mutation) with NSCLC were enrolled in the current study. The patients' overall objective response rate (ORR) was 58.3% and the disease control rate (DCR) in 36 EGFR mutation patients was 88.9%. The ORR was 7.7% and DCR was 53.8% in the wild-type patients. Median progression-free survival (PFS) with icotinib treatment in EGFR mutation patients was 9.5 months and 2.2 months in wild-type patients (P<0.001). Nineteen patients with EGFR mutation received icotinib as first-line and 17 in further-line treatment. The PFS was 9.5 months in the first-line and 8.5 months for second-line or further-line patients (P=0.41). Median overall survival (OS) in EGFR mutation patients was not reached, but was 12.6 months in wild-type patients. Most of the drug-related adverse events were mild (grade I or II) and reversible with no grade IV toxicity. Icotinib monotherapy showed significant antitumor activity in advanced NSCLC EGFR mutation patients. The toxicity was well tolerated and acceptable.

    The objective of this study was to scrutinize number line estimation behaviors displayed by children in mathematics classrooms during the first three years of schooling. We extend existing research by not only mapping potential logarithmic-linear shifts but also provide a new perspective by studying in detail the estimation strategies of individual target digits within a number range familiar to children. Typically developing children (n = 67) from Years 1-3 completed a number-to-position numerical estimation task (0-20 number line). Estimation behaviors were first analyzed via logarithmic and linear regression modeling. Subsequently, using an analysis of variance we compared the estimation accuracy of each digit, thus identifying target digits that were estimated with the assistance of arithmetic strategy. Our results further confirm a developmental logarithmic-linear shift when utilizing regression modeling; however, uniquely we have identified that children employ variable strategies when completing numerical estimation, with levels of strategy advancing with development. In terms of the existing cognitive research, this strategy factor highlights the limitations of any regression modeling approach, or alternatively, it could underpin the developmental time course of the logarithmic-linear shift. Future studies need to systematically investigate this relationship and also consider the implications for educational practice.

    In distal malignant biliary obstruction, an antireflux metal stent (ARMS) with a funnel-shaped valve is effective as a reintervention for metal stent occlusion caused by reflux. This study sought to evaluate the feasibility of this ARMS as a first-line metal stent. Patients with nonresectable distal malignant biliary obstruction were identified between April and December 2014 at three Japanese tertiary centers. We retrospectively evaluated recurrent biliary obstruction and adverse events after ARMS placement. In total, 20 consecutive patients were included. The most common cause of biliary obstruction was pancreatic cancer (75%). Overall, recurrent biliary obstruction was observed in seven patients (35%), with a median time to recurrent biliary obstruction of 246 days (range, 11 to 246 days). Stent occlusion occurred in five patients (25%), the causes of which were sludge and food impaction in three and two patients, respectively. Stent migration occurred in two patients (10%). The rate of adverse events associated with ARMS was 25%: pancreatitis occurred in three patients, cholecystitis in one and liver abscess in one. No patients experienced nonocclusion cholangitis. The ARMS as a first-line biliary drainage procedure was feasible. Because the ARMS did not fully prevent stent dysfunction due to reflux, further investigation is warranted.

    Metformin is recommended as the first-line treatment of type 2 diabetes mellitus. Despite its common use, few studies have been conducted to precisely measure the efficacy of metformin versus placebo as a first-line treatment. This study aims to assess the precise effects of metformin monotherapy on glycemic control and weight in drug-naive patients with type 2 diabetes mellitus. Medline ® and Cochrane databases were searched until March 19, 2016 to perform a systematic review and meta-analysis of placebo-controlled randomized trials evaluating metformin monotherapy in drug-naive patients with type 2 diabetes mellitus. Assessed outcomes include glycemic control (fasting plasma glucose, glycosated hemoglobin) and weight. Overall, 16 studies (1140 patients) were selected. Compared to placebo, metformin monotherapy was associated with decreased glycosated hemoglobin by 0.95% at 3 months (95% CI: 0.50 to 1.39, I 2 =87%) and 1.32% at 6 months (95% CI: 1.01 to 1.62, I 2 =71%), and decreased fasting plasma glucose by 1.92mmol/L at 1 month (95% CI: 0.11 to 3.74, I 2 =88%), 1.79mmol/L at 3 months (95% CI: 0.92 to 2.66, I 2 =88%) and 2.14mmol/L at 6 months (95% CI: 1.17 to 3.12, I 2 =82%). No significant difference was demonstrated for the comparisons of weight due to relatively small number of studies retrieved from the literature resulting in insufficient statistical power. This study provides the precise effects of metformin monotherapy regarding the decreases in fasting plasma glucose and glycosated hemoglobin that physician can expected in drug-naive patients with type 2 diabetes mellitus. No evidence was found for the effects on weight. Copyright © 2018 Société française de pharmacologie et de thérapeutique. Published by Elsevier Masson SAS. All rights reserved.

    The current management of patients with metastatic pancreatic ductal adenocarcinoma (mPDAC) is based on systemic chemotherapy. The results of the MPACT and PRODIGE clinical trials have demonstrated that the combination of nab-paclitaxel and gemcitabine (GEM) as well as FOLFIRINOX regimen result in improvement in overall survival when compared to GEM alone. Treatment guidelines now recommend either one of these two regimens as first line treatment for fit patients with mPDAC. Because no head-to-head comparison between the two regimens exists, the selection of one versus the other is based on clinical criteria. The design and eligibility criteria of these two clinical trials are dissimilar, making the results of the MPACT trial more applicable to the general population of patients with mPDAC. In addition, the combination of nab-paclitaxel and GEM is better tolerated and easier to administer in clinical practice than FOLFIRINOX. Furthermore, when the regimens are studied in comparable patient populations the efficacy results are very similar. Nanoliposomal irinotecan plus 5FU has recently demonstrated a significant increase in efficacy rates after a GEM-based treatment. Importantly, treatment of mPDAC should now be considered as a continuum care for patients who are fit, with second and even third line treatments. Different sequential treatment algorithms are proposed based on available data. In retrospective studies, patients who were managed with GEM-based regimens followed by fluoropyrimidine-based regimens appear to have the most favorable outcome. PMID:29896283

    Pure rotation lines of NH of the v = 0 level and v = 1 level are detected in high-resolution solar spectra obtained from the Atmospheric Trace Molecule Spectroscopy (ATMOS) experimental observations. It is pointed out that the identification of the lines is favored by the typical appearance of the triplet lines of nearly equal intensities. The observed equivalent widths of these triplet lines are compared with predicted intensities, and it is observed that these widths are systematically larger than the predicted values. It is noted that because these very faint lines are observed in a region where the signal is very low, a systematic error in the measurements of the equivalent widths cannot be ruled out; therefore, the disagreement between the observed and predicted intensities is not considered to be real.

    Widespread parasite resistance to first-line treatment for uncomplicated malaria leads to introduction of new drug interventions. Introducing such interventions is complex and sensitive because of stakeholder interests and public resistance. To enhance take up of such interventions, health policy communication strategies need to deliver accurate and accessible information to empower communities with necessary information and address problems of cultural acceptance of new interventions. To explore community understanding of policy changes in first-line treatment for uncomplicated malaria in Kenya; to evaluate the potential role of policy communication in influencing responses to changes in first-line treatment policy. Data collection involved qualitative strategies in a remote district in the Kenyan Coast: in-depth interviews (n = 29), focus group discussions (n = 14), informal conversations (n = 11) and patient narratives (n = 8). Constant comparative method was used in the analysis. Being malaria-prone and remotely located, the district offered an ideal area to investigate whether or not and how policy communication about a matter as critical as change of treatment policy reaches vulnerable populations. Three years after initial implementation (2009), there was limited knowledge or understanding regarding change of first-line treatment from sulphadoxine-pyrimethamine (SP) to artemether-lumefantrine (AL) for treatment of uncomplicated malaria in the study district. The print and electronic media used to create awareness about the drug change appeared to have had little impact. Although respondents were aware of the existence of AL, the drug was known neither by name nor as the official first-line treatment. Depending on individuals or groups, AL was largely viewed negatively. The weaknesses in communication strategy surrounding the change to AL included poor choice of communication tools, confusing advertisements of other drugs and conflicts between

    Background: While laser resurfacing remains the most effective treatment option for atrophic acne scars, the high incidence of post-treatment adverse effects limits its use. Fractional laser photothermolysis attempts to overcome these limitations of laser resurfacing by creating microscopic zones of injury to the dermis with skip areas in between. Aim: The aim of the present study is to assess the efficacy and safety of fractional CO2 laser resurfacing in atrophic facial acne scars. Materials and Methods: Sixty patients with moderate to severe atrophic facial acne scars were treated with 3-4 sessions of fractional CO2 laser resurfacing at 6-week intervals. The therapeutic response to treatment was assessed at each follow up visit and then finally 6 months after the last laser session using a quartile grading scale. Response to treatment was labelled as ‘excellent’ if there was >50% improvement in scar appearance and texture of skin on the grading scale while 25-50% response and <25% improvement were labelled as ‘good’ and ‘poor’ response, respectively. The overall satisfaction of the patients and any adverse reactions to the treatment were also noted. Results: Most of the patients showed a combination of different morphological types of acne scars. At the time of final assessment 6 months after the last laser session, an excellent response was observed in 26 patients (43.3%) while 15 (25%) and 19 patients (31.7%) demonstrated a good and poor response respectively. Rolling and superficial boxcar scars responded the best while pitted scars responded the least to fractional laser monotherapy. The commonest reported adverse effect was transient erythema and crusting lasting for an average of 3-4 and 4-6 days, respectively while three patients developed post-inflammatory pigmentation lasting for 8-12 weeks. Conclusions: Fractional laser resurfacing as monotherapy is effective in treating acne scars especially rolling and superficial boxcar scars with minimal

    Guidelines recommend that women with hormone receptor-positive/human epidermal growth factor receptor 2-negative (HR+/HER2-) metastatic breast cancer (mBC) initiate hormonal therapy before chemotherapy. This study compared outcomes of women with mBC who received chemotherapy first vs hormonal therapy. A retrospective cohort study of women with mBC was conducted using a large US commercial health plan database between January 1, 2008-April 30, 2013. Subjects had evidence of a HR+/HER2- tumor sub-type in a cancer registry and use of chemotherapy or hormonal therapy in claims. Subjects were continuously enrolled for ≥6 months after metastasis and assigned to cohorts for receiving chemotherapy only or hormonal therapy only during first-line (CT-1L vs HT-1L). Adjusted incidence rates of clinically significant events were compared using a negative binomial model, and adjusted healthcare costs were compared using a generalized linear model. Three hundred and twenty-four women with HR+/HER2- mBC met the selection criteria; 179 (55%) received CT-1L and 145 (45%) received HT-1L. Mortality rates did not differ between cohorts (unadjusted incidence rate ratio (IRR) = 1.67, 95% CI = 0.82-3.46; adjusted IRR = 0.64, 95% CI = 0.32-1.27). Adjusted average total all-cause healthcare costs were $11 090 for women with CT-1L and $6743 for women with HT-1L (cost ratio =1.64, 95% CI =1.36-1.99). Observed use of first-line chemotherapy (>50%) was higher than expected given the HR + molecular profile of the tumors. Chemotherapy use during first-line did not appear to be associated with a survival benefit, but was associated with significantly higher costs compared with the use of hormonal therapy during first-line; however, this comparison is limited by demographic and baseline characteristic differences between the two cohorts. This study contributes to understanding real-world treatment patterns and the associated clinical and economic outcomes of using

    Background Antiretroviral therapy (ART) has evolved rapidly since its beginnings. This analysis describes trends in first-line ART use in Asia and their impact on treatment outcomes. Methods Patients in the TREAT Asia HIV Observational Database receiving first-line ART for ≥6 months were included. Predictors of treatment failure and treatment modification were assessed. Results Data from 4662 eligible patients was analysed. Patients started ART in 2003–2006 (n = 1419), 2007–2010 (n = 2690) and 2011–2013 (n = 553). During the observation period, tenofovir, zidovudine and abacavir use largely replaced stavudine. Stavudine was prescribed to 5.8% of ART starters in 2012/13. Efavirenz use increased at the expense of nevirapine, although both continue to be used extensively (47.5% and 34.5% of patients in 2012/13, respectively). Protease inhibitor use dropped after 2004. The rate of treatment failure or modification declined over time (22.1 [95%CI 20.7–23.5] events per 100 patient/years in 2003–2006, 15.8 [14.9–16.8] in 2007–2010, and 11.6 [9.4–14.2] in 2011–2013). Adjustment for ART regimen had little impact on the temporal decline in treatment failure rates but substantially attenuated the temporal decline in rates of modification due to adverse event. In the final multivariate model, treatment modification due to adverse event was significantly predicted by earlier period of ART initiation (hazard ratio 0.52 [95%CI 0.33–0.81], p = 0.004 for 2011–2013 versus 2003–2006), older age (1.56 [1.19–2.04], p = 0.001 for ≥50 years versus <30years), female sex (1.29 [1.11–1.50], p = 0.001 versus male), positive hepatitis C status (1.33 [1.06–1.66], p = 0.013 versus negative), and ART regimen (11.36 [6.28–20.54], p<0.001 for stavudine-based regimens versus tenofovir-based). Conclusions The observed trends in first-line ART use in Asia reflect changes in drug availability, global treatment recommendations and

    Measurement of central blood pressure provides prognostic information beyond conventional peripheral blood pressure (BP). However, few studies have directly compared the effects of antihypertensives on central hemodynamics. This study investigated the effects of a low-dose combination of nifedipine Gastrointestinal Therapeutic System (GITS) and valsartan versus high-dose monotherapy with either agent in reducing central BP in essential hypertension inadequately controlled by low-dose monotherapy. In this prospective, open-label, randomized, active-controlled, multicenter 8-week study, patients not meeting the target BP after 4 weeks of treatment with low-dose monotherapy were randomized to receive nifedipine GITS 30 mg plus valsartan 80 mg (N30+V80), nifedipine GITS 60 mg (N60), or valsartan 160 mg (V160) for a further 4 weeks. Central hemodynamics were measured by applanation tonometry. A total of 391 patients were enrolled. Reduction in central systolic BP from baseline to week 8, the primary efficacy variable, was significantly greater in the N30+V80 group (-27.2±14.7 mmHg) and the N60 group (-27.1±16.5 mmHg) compared with V160 group (-14.4±16.6 mmHg). Decrease in the augmentation index in the N60 group was significantly greater compared with V160 alone, without differences between combination therapy and either high-dose monotherapy. Decreases in brachial systolic BP were significantly greater in the N30+V80 and N60 groups than in the V160 group. By multiple regression analysis, most differences in drug effects on central hemodynamics disappeared after controlling for changes in peripheral BP. A low rate of adverse events occurred in all treatment groups. A low-dose combination of nifedipine GITS plus valsartan or high-dose nifedipine was more effective in improving central hemodynamics than high-dose valsartan in patients with hypertension, mostly because of the improvement in peripheral (brachial) hemodynamics.

    To evaluate the efficacy and toxicity of the combination of ifosfamide (IFX) and vinorelbine (VNB) as first-line chemotherapy in metastatic breast cancer (MBC). Between August 1993 and August 1995, 45 patients with untreated MBC received a regimen that consisted of IFX 2 g/m2 by 1-hour intravenous (i.v.) infusion on days 1 to 3, mesna 400 mg/m2 by i.v. bolus at hours 0 and 4 and 800 mg/m2 orally at hour 8 on days 1 to 3, and VNB 35 mg/m2 by 20-minute i.v. infusion on days 1 and 15. Courses were repeated every 28 days. During the first course only, half-dose VNB (17.5 mg/m2) was administered on days 8 and 22. The median age was 53 years and 30 patients (67%) were postmenopausal. Dominant sites of disease were soft tissue in nine patients, bone in seven, and visceral in 29. Objective responses (ORs) were recorded in 25 of 43 assessable patients (58%; 95% confidence interval, 43% to 73%). Complete remissions (CRs) occurred in six patients (14%) and partial remissions (PRs) in 19 (44%). No change (NC) was recorded in 10 patients (23%) and progressive disease (PD) in eight patients (19%). The median time to treatment failure was 12 months and the median survival duration 19 months. Myelosuppression was the limiting toxicity, mainly leukopenia in 32 patients (74%). In contrast, anemia and thrombocytopenia were mild. Other significant toxicities included peripheral neuropathy in nine patients (21%), constipation in 15 (35%), and myalgias in 11 (26%). IFX/VNB is an active combination against MBC with moderate toxicity and deserves further evaluation.

    The ability of endoscopic submucosal dissection (ESD) to resect large early gastric cancers (EGCs) results in the need to treat large artificial gastric ulcers. This study assessed whether the combination therapy of rebamipide plus a proton pump inhibitor (PPI) offered benefits over PPI monotherapy. In this prospective, randomized, multicenter, open-label, and comparative study, patients who had undergone ESD for EGC or gastric adenoma were randomized into groups receiving either rabeprazole monotherapy (10 mg/day, n=64) or a combination of rabeprazole plus rebamipide (300 mg/day, n=66). The Scar stage (S stage) ratio after treatment was compared, and factors independently associated with ulcer healing were identified by using multivariate analyses. The S stage rates at 4 and 8 weeks were similar in the two groups, even in the subgroups of patients with large amounts of tissue resected and regardless of CYP2C19 genotype. Independent factors for ulcer healing were circumferential location of the tumor and resected tissue size; the type of treatment did not affect ulcer healing. Combination therapy with rebamipide and PPI had limited benefits compared with PPI monotherapy in the treatment of post-ESD gastric ulcer (UMIN Clinical Trials Registry, UMIN000007435).

    The purpose of this study was to assess the effects of an educational workshop on knowledge of and attitude toward therapeutic use of music and aesthetic experiences with music among first-line nurses. A one-group pre-test/post-test design was used. Forty-six first-line nurses, aged 21-56 years, were recruited from seven different hospitals. Questionnaires were used to assess the nurses' knowledge of and attitude toward therapeutic use of music and aesthetic experience with music before and after the workshop, and 3 months after the workshop. The workshop comprised three sessions; the nurses participated in 8h of instruction the first week and 4h, the second week covering analytical music appreciation, music staves comprehension, theory and practice of music therapy, and evidence-based music intervention. Educational workshop significantly improved knowledge of and attitudes toward therapeutic use of music and music aesthetic experiences (p<0.001). A sustained effect of the workshop was found at follow up 3-month after workshop. The mean change in scores for music aesthetic experiences between nurse with and without music backgrounds differed significantly (p=0.01). The workshop enhanced the knowledge of and attitude toward therapeutic use of music and aesthetic experiences with music among first-line nurses. Copyright © 2010 Elsevier Ltd. All rights reserved.

    Current clinical practice guidelines (CPGs) for posttraumatic stress disorder (PTSD) offer contradictory recommendations regarding use of medications or psychotherapy as first-line treatment. Direct head-to-head comparisons are lacking. Systemic review of Medline, EMBASE, PILOTS, Cochrane Central Register of Controlled Trials, PsycINFO, and Global Health Library was conducted without language restrictions. Randomized clinical trials ≥8 weeks in duration using structured clinical interview-based outcome measures, active-control conditions (e.g. supportive psychotherapy), and intent-to-treat analysis were selected for analyses. Independent review, data abstraction, and bias assessment were performed using standardized processes. Study outcomes were grouped around conventional follow-up time periods (3, 6, and 9 months). Combined effect sizes were computed using meta-analyses for medication versus control, medication pre-/posttreatment, psychotherapy versus control, and psychotherapy pre-/posttreatment. Effect sizes for trauma-focused psychotherapies (TFPs) versus active control conditions were greater than medications versus placebo and other psychotherapies versus active controls. TFPs resulted in greater sustained benefit over time than medications. Sertraline, venlafaxine, and nefazodone outperformed other medications, although potential for methodological biases were high. Improvement following paroxetine and fluoxetine treatment was small. Venlafaxine and stress inoculation training (SIT) demonstrated large initial effects that decreased over time. Bupropion, citalopram, divalproex, mirtazapine, tiagabine, and topiramate failed to differentiate from placebo. Aripiprazole, divalproex, guanfacine, and olanzapine failed to differentiate from placebo when combined with an antidepressant. Study findings support use of TFPs over nontrauma-focused psychotherapy or medication as first-line interventions. Second-line interventions include SIT, and potentially

    AIM: To evaluate the effect of first line esomeprazole (EPZ)-based triple therapy on Helicobacter pylori (H. pylori) eradication. METHODS: A total of 80 Japanese patients with gastritis who were diagnosed as positive for H. pylori infection by endoscopic biopsy-based or 13C-urea breath tests were included in this study. The average age of the patients was 57.2 years (male/female, 42/38). These patients were treated by first-line eradication therapy with EPZ 40 mg/d, amoxicillin 1500 mg/d, and clarithromycin 400 mg/d for 7 d. All drugs were given twice per day. Correlations between H. pylori eradication, CYP2C19 genotype, and serum pepsinogen (PG) level were analyzed. This study was registered with the UMIN Clinical Trials Registry (UMIN000009642). RESULTS: The H. pylori eradication rates by EPZ-based triple therapy evaluated by intention-to-treat and per protocol were 67.5% and 68.4%, respectively, which were similar to triple therapies with other first-generation proton pump inhibitors (PPIs). The eradication rates in three different CYP2C19 genotypes, described as extensive metabolizer (EM), intermediate metabolizer, and poor metabolizer, were 52.2%, 72.1%, and 84.6%, respectively. The H. pylori eradication rate was significantly lower in EM than non-EM (P < 0.05). The serum PG I level and PG I/II ratio were significantly increased after eradication of H. pylori (P < 0.01), suggesting that gastric atrophy was improved by H. pylori eradication. Thus, first-line eradication by EPZ-based triple therapy for patients with H. pylori-positive gastritis was influenced by CYP2C19 genotype, and the eradication rate was on the same level with other first-generation PPIs in the Japanese population. CONCLUSION: The results from this study suggest that there is no advantage to EPZ-based triple therapy on H. pylori eradication compared to other first-generation PPIs. PMID:26730167

    Anaplastic lymphoma kinase (ALK) gene rearrangements as driver genetic alterations occur in approximately 2-4% of non-small-cell lung cancer (NSCLC) patients. Alectinib, a next generation ALK inhibitor, recently demonstrated, in two separate Phase III trials, superior efficacy to crizotinib, the first ALK inhibitor to demonstrate clinical efficacy in ALK-positive NSCLC patients. Alectinib also demonstrated superior efficacy in the CNS. The data from these two Phase III studies suggest that the efficacy of starting with alectinib is superior to the overall clinical efficacy of starting with crizotinib followed by switching to alectinib at the time of disease progression. These results have changed the standard of care to alectinib as front-line therapy for advanced ALK-positive NSCLC patients. Areas covered: this paper reviews the available data on alectinib as front-line therapy in patients with ALK-positive NSCLC patients including its activity against brain metastases. In addition, the paper will review the data with other ALK inhibitors as front-line therapy.

    Follicular lymphoma (FL) patients experience multiple remissions and relapses and commonly receive multiple treatment lines. A crucial question is whether anthracyclines should be used at first-line or whether they would be better "reserved" for relapse and whether FL outcome can be optimized by definite sequences of treatments. Randomized trials can be hardly designed to address this question. In this retrospective multi-institutional study, time-to-next-treatment after first relapse was analyzed in 510 patients who had received either alkylating agents- or anthracycline- or nucleoside analogs-based chemotherapy with/without rituximab at first-line and different second-line therapies. After a median of 42 months, median time-to-next-treatment after relapse was 41 months (CI95%:34-47 months). After adjustment for covariates, first-line anthracycline-based chemotherapy with/without rituximab was associated with better time-to-next-treatment after any salvage than alkylating agents-based chemotherapy with/without rituximab or nucleoside analogs-based chemotherapy with/without rituximab (HR:0.74, P = 0.027). The addition of rituximab to first-line chemotherapy had no significant impact (HR:1.22, P = 0.140). Autologs stem cell transplantation performed better than any other salvage treatment (HR:0.53, P < 0.001). First-line anthracycline-based chemotherapy significantly improved time-to-next-treatment even in patients receiving salvage autologs stem cell transplantation (P = 0.041). This study supports the concept that in FL previous treatments significantly impact on the outcome of subsequent therapies. The outcome of second-line treatments, either with salvage chemoimmunotherapy or with autologs stem cell transplantation, was better when an anthracycline-containing regimen was used at first-line. © 2014 Wiley Periodicals, Inc.

    Viral hepatitis B (VHB) represents a major public health problem. Studies from HIV multidrug patients have associated the use of tenofovir disoproxil fumarate (TDF) with renal dysfunction and phosphate wasting. The aim of this study was to examine the effect of year-long TDF monotherapy on renal function in VHB patients. We evaluated adult patients diagnosed with VHB before treatment initiation (T0), and after 3 and 12 months (T3 and T12) of TDF initiation. Estimated glomerular filtration rate (eGFR) was estimated by serum cystatin C and creatinine. In addition, urinary electrolytes and tubular biomarkers (cystatin C, β2-microglobulin and neutrophil gelatinase-associated lipocalin) were analyzed, as well as parathyroid hormone (PTH) and 25(OH)vitamin D levels. After 1 year, 32 patients completed the study, 22 (68.7%) men and 12 (37.5%) Whites, mean age 44.1±12.0 years. We found that serum electrolytes were similar at baseline and 3 or 12 months after initiation of TDF monotherapy. In addition, urinary fractional excretions of electrolytes as well as proteinuria, albuminuria, urinary β2-microglobulin, and urinary cystatin C showed no significant differences across the treatment timeline. There were also no statistical differences in the eGFR. There was a statistically significant increase in the PTH (Friedman's test, P=0.012), but the 25(OH)vitamin D levels were in the normal range in the beginning and did not change at the follow-up. Moreover, there was no correlation between the initial levels of vitamin D and the corresponding increases in the PTH values. If used as monotherapy in hepatitis B patients for a 12-month period, TDF is not associated with changes in either eGFR or a panel of urinary biomarkers. Serum and urinary electrolytes also remained unchanged. Of note, a significant increase in the PTH was found, although not related to the 25(OH)vitamin D initial status.

    Artemisinin-based combination therapy (ACT) is a key strategy for global malaria elimination efforts. However, the development of artemisinin-resistant malaria parasites threatens progress and continued usage of oral artemisinin monotherapies (AMT) predisposes the selection of drug resistant strains. This is particularly a problem along the Myanmar/Thailand border. The artemisinin monotherapy replacement programme (AMTR) was established in 2012 to remove oral AMT from stocks in Myanmar, specifically by replacing oral AMT with quality-assured ACT and conducting behavioural change communication activities to the outlets dispensing anti-malarial medications. This study attempts to quantify the characteristics of outlet providers who continue to stock oral AMT despite these concerted efforts. A cross-sectional survey of all types of private sector outlets that were stocking anti-malarial drugs in 13 townships of Eastern Myanmar was implemented from July to August 2014. A total of 573 outlets were included. Bivariate and multivariable logistic regressions were conducted to assess outlet and provider-level characteristics associated with stocking oral AMT. In total, 2939 outlets in Eastern Myanmar were screened for presence of any anti-malarial drugs in August 2014. The study found that 573 (19.5 %) had some kind of oral anti-malarial drug in stock at the time of survey and among them, 96 (16.8 %) stocked oral AMT. In bivariate analyses, compared to health care facilities, itinerant drug vendors, retailers and health workers were less likely to stock oral AMT (33.3 vs 12.9, 10.0, 8.1 %, OR = 0.30, 0.22, 0.18, respectively). Providers who cut blister pack or sell partial courses (40.6 vs 11.7 %, OR 5.18, CI 3.18-8.44) and those who based their stock decision on consumer demand (32.8 vs 12.1 %, OR 3.54, CI 2.21-5.63) were more likely to stock oAMT. Multivariate logistic regressions produced similar significant associations. Private healthcare facilities and drug

    To retrospectively evaluate the clinical and echocardiographic criteria of thrombolytic therapy for mechanical heart valve thrombosis. Nineteen consecutive patients with 22 instances of prosthetic heart valve thrombosis (14 mitral, 2 aortic, 3 tricuspid, and 3 pulmonary) were treated with short-course thrombolytic therapy as first option of treatment in absence of contraindications. The thrombolytic therapy protocol consisted of streptokinase (1,500,000 IU in 90 minutes) (n = 18) in one (n = 7) or two (n = 11) cycles or recombinant tissue-type plasminogen activator (100 mg in 90 minutes) (n = 4). Overall success was seen in 82%, immediate complete success in 59%, and partial success in 23%. Six patients without total response to thrombolytic therapy underwent surgery, and pannus was observed in 83%. Six patients showed complications: allergy, stroke, transient ischemic attack, coronary embolism, minor bleeding, and one death. At diagnosis, 10 patients evidenced atrial thrombus by transesophageal echocardiography, 3 of whom experienced peripheral embolism during thrombolysis. Four episodes of rethrombosis were observed (16%). The survivorship was 84% with a mean follow-up of 42.6 months. A short-course of thrombolytic therapy may be considered first-line therapy for prosthetic heart valve thrombosis. The risk of peripheral embolism may be evaluated for the presence of atrial thrombus by transesophageal echocardiography at diagnosis.

    Cancer patients with complicated infections following abdominal surgery represent one of the worst clinical scenarios that is useful for testing the efficacy of empirical antimicrobial therapy. No study so far has evaluated the performance of tigecycline (TIG) when administered as empirical first-line treatment in a homogeneous population of surgical cancer patients with a febrile episode. An observational review of the data records of 24 sequential patients receiving TIG for a febrile episode following a major abdominal procedure in a single cancer institute was performed. Large bowel surgery represented 68% of all procedures, followed by gastric surgery (16%) and urinary-gynaecologic-biliary surgery (16%). Complications following surgery were observed in 68% of febrile episodes, with peritonitis and sepsis accounting for 59% and 24% of complications, respectively. Eight patients needed repeat surgery for source control. The mean duration of TIG treatment was 8 days. Causative pathogens were detected in 16 episodes (64%), and a total of 44 microorganisms were recovered (29% Escherichia coli, 9% Enterococcus faecalis and 9% coagulase-negative staphylococci). TIG was effective in 12 episodes (48%). The success rate was 67% when infectious episodes sustained by intrinsically resistant bacteria and fungi were excluded. Treatment failure was associated with the presence of complications and with microbiologically documented infection. TIG may be useful as a first-line treatment option in cancer patients requiring antibiotic treatment following surgery when complications are not present or suspected on clinical grounds and when local microbial epidemiology shows a low incidence of primary resistant bacteria.

    With widespread use of antiretroviral (ARV) drugs in Africa, one of the major potential challenges is the risk of emergence of ARV drug-resistant HIV strains. Our objective is to evaluate the virological failure and genotypic drug-resistance mutations in patients receiving first-line highly active antiretroviral therapy (HAART) in routine clinics that use the World Health Organization public health approach to monitor antiretroviral treatment (ART) in Togo. Patients on HAART for one year (10-14 months) were enrolled between April and October 2008 at three sites in Lomé, the capital city of Togo. Plasma viral load was measured with the NucliSENS EasyQ HIV-1 assay (Biomérieux, Lyon, France) and/or a Generic viral load assay (Biocentric, Bandol, France). Genotypic drug-resistance testing was performed with an inhouse assay on plasma samples from patients with viral loads of more than 1000 copies/ml. CD4 cell counts and demographic data were also obtained from medical records. A total of 188 patients receiving first-line antiretroviral treatment were enrolled, and 58 (30.8%) of them experienced virologic failure. Drug-resistance mutations were present in 46 patients, corresponding to 24.5% of all patients enrolled in the study. All 46 patients were resistant to non-nucleoside reverse-transcriptase inhibitors (NNRTIs): of these, 12 were resistant only to NNRTIs, 25 to NNRTIs and lamivudine/emtricitabine, and eight to all three drugs of their ARV regimes. Importantly, eight patients were already predicted to be resistant to etravirine, the new NNRTI, and three patients harboured the K65R mutation, inducing major resistance to tenofovir. In Togo, efforts to provide access to ARV therapy for infected persons have increased since 2003, and scaling up of ART started in 2007. The high number of resistant strains observed in Togo shows clearly that the emergence of HIV drug resistance is of increasing concern in countries where ART is now widely used, and can compromise the

    The World Health Organization Antiretroviral Treatment Guidelines recommend phasing-out stavudine because of its risk of long-term toxicity. There are two mutational pathways of stavudine resistance with different implications for zidovudine and tenofovir cross-resistance, the primary candidates for replacing stavudine. However, because resistance testing is rarely available in resource-limited settings, it is critical to identify the cross-resistance patterns associated with first-line stavudine failure. We analyzed HIV-1 resistance mutations following first-line stavudine failure from 35 publications comprising 1,825 individuals. We also assessed the influence of concomitant nevirapine vs. efavirenz, therapy duration, and HIV-1 subtype on the proportions of mutations associated with zidovudine vs. tenofovir cross-resistance. Mutations with preferential zidovudine activity, K65R or K70E, occurred in 5.3% of individuals. Mutations with preferential tenofovir activity, ≥ two thymidine analog mutations (TAMs) or Q151M, occurred in 22% of individuals. Nevirapine increased the risk of TAMs, K65R, and Q151M. Longer therapy increased the risk of TAMs and Q151M but not K65R. Subtype C and CRF01_AE increased the risk of K65R, but only CRF01_AE increased the risk of K65R without Q151M. Regardless of concomitant nevirapine vs. efavirenz, therapy duration, or subtype, tenofovir was more likely than zidovudine to retain antiviral activity following first-line d4T therapy.
