    ABSTRACT: Antibiotic-impregnated bone cement spacer (ACS) with tobramycin ± vancomycin is commonly used in a 2-stage replacement of infected prosthetic joints. This procedure has been associated with development of acute kidney injury (AKI). To determine the incidence and risk factors for AKI after implantation of tobramycin-impregnated ACS. This prospective, observational study evaluated 50 consecutive patients who received tobramycin ACS for first-stage revision of an infected hip or knee arthroplasty from August 2011 to February 2013. AKI was defined as 50% or greater rise in serum creatinine (SCr) from baseline within the first 7 postoperative days (PODs). The incidence of AKI was 20%, with median onset occurring at POD 2 (interquartile range [IQR] = 1-3); patients with AKI had a longer median duration of hospital stay (16 days, IQR = 12-17, vs 10 days, IQR = 8-10; P = 0.03). Serum tobramycin concentrations were significantly higher in the AKI group, peaking on POD 1 (median 1.9 vs 0.9 µg/mL, P = 0.01). Risk factors for nephrotoxicity identified by multivariate analysis were use of bone cement premanufactured with gentamicin (OR = 8.2; 95% CI = 1.1-60; P = 0.04), administration of blood transfusions intraoperatively (OR = 32.5; 95% CI = 2.3-454.3; P = 0.01) and nonsteroidal anti-inflammatory drugs postoperatively (OR = 23.0; 95% CI = 1.3-397.7; P = 0.03). Tobramycin ACS is associated with a high risk of AKI. Measures to minimize AKI risk in the perioperative period include early detection through close monitoring of SCr, avoiding use of premanufactured bone cement containing gentamicin, and avoiding potential nephrotoxins within the first 72 hours postoperatively. © The Author(s) 2015.

    ABSTRACT: Specialized chronic heart failure (HF) clinics have demonstrated significant reductions in readmissions. Limited evidence is available regarding HF clinics in the immediate post-discharge period. To evaluate the effect of a multidisciplinary HF clinic on 90-day readmission rates and all-cause mortality in those recently discharged from a HF hospitalization. In this retrospective cohort study, patients discharged with a primary HF diagnosis who attended the HF postdischarge clinic in 2010-2012 were compared with controls from 2009. During 6 clinic visits, patients were seen by a physician assistant, clinical pharmacist specialist, and case manager, with care overseen by a cardiologist. The program focused on optimizing therapy, identifying HF etiology/precipitating factors, medication titration, education, and medication adherence. The primary outcome was 90-day HF readmission. A multivariate Cox proportional hazards model was used to compare outcomes. Among the 277 patients (144 clinic, 133 control) in the study, 7.6% of patients in the clinic and 23.3% of patients in the control group were readmitted for HF within 90 days (aHR (adjusted hazard ratio) = 0.17; 95% CI = 0.07-0.41; P < 0.001; ARR (absolute risk reduction) = 15.7%; NNT (number needed to treat) = 7). Clinic patients had lower 90-day time-to-first HF readmission or all-cause mortality (9.0% vs 28.6%; aHR = 0.28; 95% CI = 0.06-0.31; P < 0.001; ARR = 19.6%; NNT = 6). The multidisciplinary HF posthospitalization outpatient program was associated with a significant reduction in 90-day HF readmissions in patients who were recently discharged from a HF hospitalization. © The Author(s) 2015.

    ABSTRACT: To describe the studies evaluating the efficacy and safety of new insulin glargine 300 U/mL (Gla-300) as a basal insulin in the treatment of type 1 (T1DM) and type 2 (T2DM) diabetes mellitus. A literature search of MEDLINE was conducted (January 2008-June 2015) using the terms U300, Gla-300, and insulin glargine 300 units/mL and supplemented with congress abstracts published in 2014 and 2015. All English language studies assessing the efficacy and/or safety of Gla-300 were evaluated. The efficacy and safety of once-daily Gla-300 has been compared with insulin glargine 100 U/mL (Gla-100) in the EDITION trials, 6 phase-3, multinational, open-label studies in T1DM and T2DM. Across these studies, Gla-300 consistently demonstrated glycemic control comparable to Gla-100; a mean (standard error) change in glycated hemoglobin A1c of -1.02% (0.03) with both Gla-100 (n = 1235) and Gla-300 (n = 1239) was seen in a patient-level meta-analysis. Gla-300 was associated with comparable or reduced nocturnal hypoglycemia compared with Gla-100; the relative risk for nocturnal hypoglycemia with Gla-300 versus Gla-100 was 0.75 (95% CI = 0.68 to 0.83) in a patient-level meta-analysis. There is also some evidence for less weight gain with Gla-300 compared with Gla-100, despite a higher insulin dose. Gla-300 was well tolerated, with the number of adverse events being comparable to that with Gla-100. These results suggest that Gla-300 may have a place as an alternative, long-acting basal insulin for patients with T1DM or T2DM, with the possibility for improved tolerability. © The Author(s) 2015.

    ABSTRACT: Although it is generally accepted that anticholinergic use may lead to a fall, results from studies assessing the association between anticholinergic use and falls are mixed. In addition, direct evidence of an association between use of anticholinergic medications and recurrent falls among community-dwelling elders is not available. To assess the association between anticholinergic use across multiple anticholinergic subclasses, including over-the-counter medications, and recurrent falls. This was a longitudinal analysis of 2948 participants, with data collected via interview at year 1 from the Health, Aging and Body Composition study and followed through year 7 (1997-2004). Self-reported use of anticholinergic medication was identified at years 1, 2, 3, 5, and 6 as defined by the list from the 2015 American Geriatrics Society Beers Criteria. Dosage and duration were also examined. The main outcome was recurrent falls (≥2) in an ensuing 12-month period from each medication data collection. Using multivariable generalized estimating equation models, controlling for demographic, health status/behaviors, and access-to-care factors, a 34% increase in likelihood of recurrent falls in anticholinergic users (adjusted odds ratio = 1.34; 95% CI = 0.93-1.93) was observed, but the results were not statistically significant; similar results were found with higher doses and longer duration of use. Increased point estimates suggest an association of anticholinergic use with recurrent falls, but the associations did not reach statistical significance. Future studies are needed for more definitive evidence and to examine other measures of anticholinergic burden and associations with more intermediate adverse effects such as cognitive function. © The Author(s) 2015.

    ABSTRACT: To review clinical outcomes data for patients treated with oral ribavirin for noninfluenza respiratory viral infections (NIRVIs). MEDLINE, EMBASE, and PubMed Central (1972 to June 1, 2015) were queried with the following search term combinations: "Oral" AND "ribavirin" AND ("respiratory syncytial virus" OR "metapneumovirus" OR "parainfluenza" OR "coronavirus" OR "rhinovirus" OR "enterovirus" OR "adenovirus"). Included studies must have characterized the clinical outcomes of a cohort of patients treated with oral ribavirin for symptomatic NIRVIs. Case reports and series with <5 cases, conference abstracts, and articles written in languages other than English were excluded. Of the 1256 unique reports, 15 met inclusion criteria: 12 retrospective, 3 prospective, and 3 comparative with untreated control groups. All studies except for 2 Middle East respiratory syndrome coronavirus (MERS-CoV) studies were in immunocompromised patients (9 malignancy/stem cell transplant, 4 lung transplant). The mortality rate ranged from 0% to 31% in malignancy/stem cell transplant recipients treated with oral ribavirin, and 1/108 (0.9%) ribavirin-treated lung transplant recipients died at 30 days. Three studies (one each for malignancy, lung transplant, and MERS-CoV) suggested a clinical outcomes benefit with oral ribavirin compared with supportive care alone; however, the nonrandomized design precludes efficacy determination. Hemolysis was the most common adverse reaction, occurring in 14% (54/375) of patients. Ribavirin was discontinued in 4% of patients secondary to adverse reactions. Oral ribavirin should be considered for the treatment of NIRVI in immunocompromised adults (malignancy/stem cell transplant or lung transplant) or adults with MERS-CoV. © The Author(s) 2015.

    ABSTRACT: Recently, a case report described a decrease in frequency of stuttering after intake of methylphenidate (MPH). This study was undertaken to investigate if this effect could again be reproduced in a population of young healthy male adult persons with developmental stuttering. A double-blind randomized crossover trial, with a 2-week washout period, including 15 Dutch-speaking young healthy persons with developmental stuttering, assessed the effects of a single dose of 20 mg MPH compared with placebo on stuttering. Dependent and 1-sample t tests were used to detect significant differences. The end point was the number of stutter moments and self-perceived improvement. MPH yielded a significant decrease in the number of stutter moments when reading and speaking (P = 0.002), which was not the case with placebo (P = 0.090). There was a significant improvement from baseline after intake of MPH as compared with placebo (P = 0.003). Self-perceived improvement with MPH was not significantly better as compared with placebo (P = 0.28). This study showed that the participants had an objective statistically significant decrease in the frequency of stuttering with MPH, and this was not the case with placebo. This was also the case for a reduction in stutter moments when reading out loud and speaking spontaneously. However, this result was not subjectively perceived by the participants. © The Author(s) 2015.

    ABSTRACT: Inhaled nitric oxide and inhaled epoprostenol have been evaluated for the management of hypoxemia in acute respiratory distress syndrome, with clinical trials demonstrating comparable improvements in oxygenation. However, these trials have several limitations, making it difficult to draw definitive conclusions regarding clinical outcomes. The aim of this study was to evaluate the noninferiority and safety of inhaled epoprostenol compared with inhaled nitric oxide in mechanically ventilated acute respiratory distress syndrome (ARDS) patients with a primary outcome of ventilator-free days from day 1 to day 28. This was a retrospective, noninterventional, propensity-matched, noninferiority cohort study. Propensity score for receipt of inhaled nitric oxide was developed and patients were matched accordingly using a prespecified algorithm. Secondary objectives included evaluating day 28 intensive care unit-free days, changes in PaO2/FiO2 ratio after inhalation therapy initiation, and hospital mortality. Safety endpoints assessed included hypotension, methemoglobinemia, renal dysfunction, rebound hypoxemia, significant bleeding, and thrombocytopenia. Ninety-four patients were included, with 47 patients in each group. Patients were well-matched with similar baseline characteristics, except patients in inhaled nitric oxide group had lower PaO2/FiO2 ratio. Management of ARDS was similar between groups. Mean difference in ventilator-free days between inhaled epoprostenol and inhaled nitric oxide was 2.16 days (95% confidence interval = -0.61 to 4.9), with lower limit of 95% confidence interval greater than the prespecified margin, hence satisfying noninferiority. There were no differences in any secondary or safety outcomes. Inhaled epoprostenol was noninferior to inhaled nitric oxide with regard to ventilator-free days from day 1 to day 28 in ARDS patients. © The Author(s) 2015.

    ABSTRACT: Extrapyramidal reactions (EPRs) associated with serotonergic antidepressant treatments have been reported since 1958. These reactions can be distressing for patients and complicate treatment. Our objective was to complete a follow-up review of published EPR cases reported for serotonergic antidepressants. Published cases between January 1998 and May 2015 were collected through a medical literature search. Citation reference lists were also searched manually. Identified cases were reviewed for patient age, gender, psychiatric diagnosis, dosage, time to reaction onset, concurrent medications, and EPR description. Cases were excluded when there was not a clear description, if descriptions were not consistent with accepted definitions, or if the written English was poor. We included cases of akathisia, dystonia, dyskinesia, parkinsonism, or mixed EPRs. Authors scored each case using the Naranjo adverse drug reaction probability scale. We identified 86 published reports involving 91 patients; selective serotonin reuptake inhibitors were implicated in 80.2% of cases. All EPR types were reported: 17 akathisia cases, 18 dyskinesia cases, 27 dystonia cases, 19 parkinsonism cases, and 10 mixed EPR cases. EPRs typically occurred within 30 days of either treatment initiation or dose increase. Age, gender, antidepressant dosing, or concurrent antipsychotic treatment did not appear to broadly contribute to EPR risk. Naranjo scores ranged from 2 to 8. Case reports associating serotonergic antidepressants with EPRs continue to be published. Practitioners are advised that monitoring for such is important. Rigorous research efforts are needed to better understand the clinical risk factors for these adverse drug reactions. © The Author(s) 2015.

    ABSTRACT: To review and summarize data on idelalisib, which was approved by the Food and Drug Administration (FDA) in July 2014 for use in combination with rituximab for relapsed chronic lymphocytic leukemia (CLL). A literature search using PubMed was conducted from January 2011 through May 2015 using the terms idelalisib, GS-101, CAL-101, PI3Kδ, and CLL. Data were also obtained through the FDA briefing documents, American Society of Clinical Oncology, and American Society of Hematology abstracts. The literature search was limited to human studies published in English. Priority was placed on trials of idelalisib in CLL. Idelalisib is a potent, first-in-class selective inhibitor of phosphatidylinositol-3-kinaseδ (PI3Kδ) approved by the FDA in July 2014 for the treatment of relapsed CLL, in combination with rituximab, in patients for whom rituximab monotherapy would be considered appropriate due to other comorbidities. PI3Kδ is hyperactivated in B-cell malignancies and plays a vital role in the B-cell receptor pathway, a key oncogenic driver in various B-cell malignancies, including CLL. Several phase I/II studies have demonstrated clinical activity of idelalisib in CLL, particularly in the setting of relapsed/refractory disease, with overall response rate ranging from 70% to 82%. The FDA approval was based on a phase III, randomized trial of rituximab monotherapy (n = 110) or idelalisib in combination with rituximab (n = 110) in heavily, pre-treated patients (median of 3 prior therapies) with relapsed CLL. Idelalisib was administered as 150 mg orally twice daily. Idelalisib plus rituximab was associated with an overall response rate of 81% and overall survival of 91% at 12 months. The median progression-free survival was not reached in the idelalisib arm at the time of the first interim analysis. The incidence of grade 3 or higher adverse events in the idelalisib plus rituximab arm was as follows: neutropenia (34%), thrombocytopenia (10%), anemia (5%), elevation in transaminases (5%), and diarrhea (4%). Idelalisib in combination with rituximab is a safe and effective new treatment option for patients with relapsed CLL, including those with poor prognostic factors. As the results from various ongoing studies become available, the role of idelalisib will likely continue to expand. © The Author(s) 2015.

    ABSTRACT: To evaluate the clinical role of LCZ696, a novel angiotensin-neprilysin inhibitor, for the treatment of chronic heart failure with a reduced ejection fraction (HFrEF). A search of PubMed was conducted using a combination of the search terms LCZ696, neprilysin inhibition, natriuretic peptide system, renin-angiotensin system, and heart failure with reduced ejection fraction. Bibliographies of all retrieved articles were reviewed for relevant literature. All references included were published between 1980 and May 2015. All studies and review articles that contained data describing the use of LCZ696 in HFrEF were reviewed. HFrEF remains a disease of high morbidity and mortality. Natriuretic peptide (NP) augmentation has emerged as a most promising, novel neurohormonal target in HFrEF. NPs provide vasodilatory, natriuretic, diuretic, and antiproliferative actions to help support the failing heart. Neprilysin, a neutral endopeptidase, is a primary pathway for NP metabolism. LCZ696 consists of the neprilysin inhibitor sacubitril (AHU377) and the angiotensin receptor blocker valsartan. Combined inhibition of the renin angiotensin aldosterone system and neprilysin augments the beneficial NP neurohormonal pathway while providing direct antagonism to increases in angiotensin II. In the PARADIGM HF trial, LCZ696 significantly improved morbidity and mortality over enalapril, a standard of care in HFrEF. Application of these results to clinical practice requires careful considerations of trial design, study patient population, and clinical monitoring. LCZ696 significantly improved morbidity and mortality in patients with chronic HFrEF but will require careful application to "real-world" populations of HFrEF. © The Author(s) 2015.

    ABSTRACT: Acute kidney injury (AKI) in patients receiving vancomycin has been associated with trough concentrations ≥15 mg/L and longer therapy duration. The objective of this study was to determine the incidence and factors associated with late AKI in children receiving ≥8 days of vancomycin therapy. Children aged 30 days to 17 years who were admitted to our institution and received intravenous vancomycin for at least 8 days during January to December of 2007 and 2010 and had a suspected or proven gram-positive infection were included. Late AKI was categorized as AKI occurring after the first 7 days of therapy and within 48 hours following vancomycin discontinuation. The primary outcome was incidence of late AKI as determined by modified pRIFLE criteria. One-hundred sixty-seven patients were included, with a median (interquartile range) age (years) and weight (kg) of 2 (1-7) and 12.5 (8.9-23.8). Late AKI was identified in 12.6% (21/167). A higher percentage of late AKI patients received concomitant treatment with intravenous acyclovir, amphotericin products, or piperacillin-tazobactam. Age <1 year was the only factor independently associated with late AKI development (odds ratio = 4.4; 95% confidence interval = 1.3-15.4). Late AKI occurred in nearly 13% of children receiving ≥8 days of vancomycin therapy. This study suggests that vancomycin trough concentrations are not associated with late AKI, but that age <1 year and concomitant administration of certain nephrotoxins may be factors associated with increased risk. © The Author(s) 2015.

    ABSTRACT: Capecitabine plus oxaliplatin (CapeOx) ± bevacizumab therapy is associated with a high incidence of hand-foot skin reaction (HFSR), hindering treatment. However, timing of onset and risk factors remain unclear. This study examined the development of HFSR and risk factors for its exacerbation to a serious condition in CapeOx ± bevacizumab therapy. We retrospectively examined patients with colorectal cancer receiving CapeOx ± bevacizumab therapy between October 1, 2009, and March 31, 2012. The observation period was defined as lasting until completion of 8 cycles. The relationship between cumulative dose of capecitabine and cumulative proportion of patients developing HFSR was evaluated by Kaplan-Meier methods. Risk factors for exacerbation of HFSR to a serious condition were assessed by multiple logistic regression. Data for 203 patients were analyzed. For patients treated at cumulative capecitabine doses of 100 000 mg/m(2) and 200 000 mg/m(2), Grade 1 HFSR occurred in ≥80% and ≥90%, respectively, and moderate-to-severe HFSR (Grade 2+) occurred in ≥10% and ≥20%, respectively. Multivariate analysis showed significant associations with diabetes (odds ratio [OR] = 4.79; 95% confidence interval [CI] = 1.86-12.34; P = 0.001), concomitant use of bevacizumab (OR = 6.01; 95% CI = 2.20-16.41; P = 0.001), history of fluorinated pyrimidine administration (OR = 2.42; 95% CI = 1.10-5.33; P = 0.027), and early onset (within 21 days) of Grade 1 HFSR (OR = 3.78; 95% CI = 1.64-8.70; P = 0.001). HFSR in CapeOx therapy is a cumulative toxicity and risk of exacerbation to a serious condition increases with diabetes, concomitant use of bevacizumab, history of fluorinated pyrimidine administration, and onset of Grade 1 HFSR within 21 days. © The Author(s) 2015.
