2011, 80: 834-844. Visualization, The ESS takes into account the fact that unequal numbers of diseased and non-diseased reduce the precision of the test accuracy estimates [19]. Availability of the two-by-two tables of the included studies was not amongst the inclusion criteria to generate a representative cohort of reviews without possible selection on high level of reporting and perhaps review quality [21]. 10.1530/EJE-11-0476. In case the number of differences between reviewers was <3%, no further data checking was done. Yes Also shown is the MIC50 of S. aureus (0.25 mg/L). 10.1016/j.acra.2011.08.013.

After everyone agreed on the data-extraction form, the actual extraction was then done by one reviewer (WE). rMATS: robust and flexible detection of differential alternative splicing from replicate RNA-Seq data. One good starting point, however, is the use of life history traits to begin describing (putative) ∗ Corresponding tiple author. PLoS One. Find books Compliance with oral administration is further compromised by the widespread recommendation that flucloxacillin should be taken on an empty stomach [1–4]. 1997, 18: 431-444. Comparison of probability of target attainments for fed versus fasting across a range of minimum inhibitory concentrations (MICs) were in line with these results. 2012, 14: 18-28. Takakuwa KM, Keith SW, Estepa AT, Shofer FS: A meta-analysis of 64-section coronary CT angiography findings for predicting 30-day major adverse cardiac events in patients presenting with symptoms suggestive of acute coronary syndrome. 2014; Kirk et al. Two review authors mentioned that a minimum of twenty homogeneous studies was required to perform a test [71, 72]. An fT>MIC of 50–60% of the dosing interval is required for maximum bacterial killing of staphylococci and 90–100% for streptococci [8,10]. They mainly use suboptimal methods like the Begg and Egger tests that are not developed for DTA meta-analyses. The search was performed in February 2012 by one author (EO) using a search filter for systematic reviews available from PubMed combined with a methodological filter for DTA studies: (systematic[sb] AND (("diagnostic test accuracy" OR DTA[tiab] OR "SENSITIVITY AND SPECIFICITY"[MH] OR SPECIFICIT*[TW] OR "FALSE NEGATIVE"[TW] OR ACCURACY[TW]))) [20]. The observed versus model-predicted concentration data are shown in Fig 3. ML has contributed to the protocol of the study, performed the selection process of studies, helped with data-checking and contributed to the manuscript. statement and Josephus' Account of the Early Divided Monarchy Christopher Begg et al. Differences in achievement of pharmacodynamic targets were minor and ranged from a small reduction in PTA for a free concentration target of greater than 0.5 mg/L for 30% of the dose interval, bioequivalence for a target of 50%, and non-inferiority for a target of 70%. Methodology, Conceptualization, The applied tests were Egger’s test (n = 18), Deeks’ test (n = 12), Begg’s test (n = 5), both the Egger and Begg test (n = 4), and both the Begg-Mazumdar and Harbord’s test [70]. Starring: R.C. Lancet. EO contributed to the protocol and performed the search and selection process of studies. EUCAST tables contain no MICs for flucloxacillin (www.eucast.org). Aseismic uplift has been ascribed to a number of mechanisms including, sediment underplating [Angelier et al., 1982; Gallen et al., 2014; Strobl et al., 2014], return flow of lithospheric material from the subduction channel [Meier et al., 2006; Becker et al., 2010] and isostatic adjustments to mass deficit beneath Crete [Snopek et al., 2007]. JAMA. A priori the expected model for oral flucloxacillin was a one-compartment model with first-order absorption [16]. Yes Six reviews based their conclusion about publication bias only on the plots, as they had not performed a test. Residual connections were introduced in (He et al. BMC Cancer. Proc. The simulation study of Deeks et al. PLOS ONE promises fair, rigorous peer review, broad scope, and wide readership – a perfect fit for your research every time.. Acad Radiol. Outcomes after cessation of mepolizumab therapy in severe eosinophilic asthma: a 12-month follow-up analysis. Stat Med. Lasting Love: How to Avoid Marital Failure by Alistair Begg and Howard Hendricks | Jul 7, 2015 On the first study day, volunteers were randomized so that half (n = 6) received the flucloxacillin after a high-fat high-calorie breakfast (fed state) and half received flucloxacillin on an empty stomach (fasting state). These results support the validity of the model and show that the major effects of food were an increase in the Tlag and a decrease in the rate of absortion. The data in the original publications cannot be accurately re-evaluated according to current pharmacodynamic end points as free flucloxacillin concentrations (i.e. Solomon et al, (2014). 2007; Otto et al. Total and free concentrations of flucloxacillin were analysed using a simple and validated LC-MS/MS method [14]. 10.1016/j.parkreldis.2011.09.015. All authors read and approved the final manuscript. There is some evidence that NC may mediate the relationship between exposure to nature and well-being (Mayer et al. The aim of this systematic review was to provide an update of the evidence for stroke rehabilitation interventions in the domain of PT. Flucloxacillin 1000 mg orally was given to 12 volunteers, after a standardised breakfast and while fasting, on two separate occasions. Validation, Cell division is the process by which new cells are made. Of the 50 diagnostic reviews that were included in this study, nine (18%) used funnel plot asymmetry to investigate publications bias and in three (6%) a statistical test. 10.4149/neo_2012_020.

In a third study, patients (rather than healthy volunteers) receiving oral flucloxacillin every 8 hours therapeutically, administered after food, had mean peak serum concentrations 25–30% lower than when taken fasting [7]. 3. Eleven reviews that did not assess publication bias mentioned that the possible existence of publication bias could be a limitation to the results of their review. 10.1016/j.acra.2011.10.027. PLoS One. Article  (Cadrin et al., 2013). As a non-essential metal, Cd is toxic to aquatic organisms even at low concentrations (Qu et al., 2013; Wang and Rainbow, 2006; Wu et al., 2017). https://doi.org/10.1371/journal.pone.0199370.g003. Volunteers were excluded if they took any regular medication (other than a hormonal oral contraceptive pill) or were intolerant of fasting for up to 10 hours. 2011, 130: 11-18. Terms and Conditions, Our questionnaire covered risk perception … Finally, it should not be assumed that the findings of this study extend to other isoxazolyl penicillins, but this too warrants further investigation. Edited by: Higgins JPT, Green S. 2009, Oxford, United Kingdom: Wiley-Blackwell, 310-324. Furthermore, Spoorthy et al. In determining if authors would assess publication bias in their reviews, we scored if authors described a method how they would investigate publication bias like drawing a funnel plot or performing a test for publication bias. View Article Biometrics. (1989), and the extension of the three-time-level approach to a non-hydrostatic coordinate has been demonstrated by Tanguay et al. The frequent detection of Cd in marine organisms is therefore of considerable … They concluded that failure to publish and selective publication were prevalent in diagnostic accuracy studies but the dataset was too small to draw firm conclusions [16]. Empirical studies to assess and understand the mechanisms that may induce publication bias in DTA studies, however, are needed. 2014 Update Flucloxacillin taken with food was associated with a significant reduction in free and total AUC and Cmax, and a prolonged Tmax, as shown with total flucloxacillin concentrations in previous studies [5,6]. At the start of each study day, an intravenous catheter was inserted, baseline blood samples were taken and the catheter was flushed with 5 mL of sodium chloride 0.9%. We have no competing interest to report that could have affected the results of our study. Maar al met al heeft op het eind van het basisonderwijs 17,5% een leeftijdsachter- stand opgelopen. Objective: To systematically review the efficacy of advance care planning (ACP) interventions in different adult patient populations. 2014A is ideal for manufacturing high-strength components. It has the same interpretation as Harrell's C for survival data (implemented in the rcorr.cens function of the Hmisc package).BeggC is restricted to Cox regression. Design: Systematic review and meta-analyses. When the decision to publish the results of a study depends on the nature and direction of the results, publication bias arises. Request PDF | On Mar 4, 2014, Gül Kremer published Chung et al. The objective of this study was to estimate the difference in dietary GHG emissions between self-selected meat-eaters, fish-eaters, vegetarians and vegans in the UK. Radiology. 1990, 263: 1385-1389. Serrated line: fed; continuous line: fasting. Eur J Heart Fail 11:292–298. These findings in adults may not translate directly into the paediatric population and this would be worthy of further study given that oral administration of flucloxacillin is particularly difficult in children [27]. This publication should be cited as: Begg et al. 2011, 11: 280-10.1186/1471-2334-11-280. 2011, 18: 1522-1528. Empirical study. 10.1016/j.gie.2011.07.026. 2012, 16: 1019-1028.

Although the best stock identifica-tion approach involves multiple methods in an interdisciplinary analysis (Begg and Waldman, 1999; Abaunza et al., 2013), such studies are not always feasible. She helped with data-checking and contributed to the manuscript. Neoplasma. Using the ESS instead of total sample size will reduce the unequal numbers of diseased and non-diseased and thereby enhance the precision of the accuracy estimates. Bates and McDonald (1982), McDonald (1986), Leslie and Purser (1991), McDonald and Haugen (1992), The Deeks test that is especially developed for reviews of diagnostic accuracy was only used in 12 reviews (10.5%). J Urol. This function implements the C-statistic proposed by Begg et al. J Gastrointest Surg. An important aspect of integrated flood risk management (FRM) around the world is accepted as being the involvement of a range of stakeholders in … For a PTA for 30% of the dosing interval, food shifted the curve to the left for both 6- and 8-hour dosing. No, Is the Subject Area "Adjustment of dosage at steady state" applicable to this article? 1994, 50: 1088-1101. J Clin Epidemiol. The majority of the methods to investigate publication bias in terms of small study-effects are developed for meta-analyses of intervention studies, leaving authors of diagnostic test accuracy (DTA) systematic reviews with limited guidance. It has a narrow spectrum of antimicrobial activity, is inexpensive, and is available in oral and intravenous formulations. Methods to investigate publication bias are developed to investigate publication bias in meta-analyses [14]. 2004, Begg et al.

Honey badger populations are typically found within the Southern African area, though it has been found tat some populations have spread to the Arabian, Iran, and Western Asian habitats (Verwey et al. Kobayashi Y, Hayashino Y, Jackson JL, Takagaki N, Hinotsu S, Kawakami K: Diagnostic performance of chromoendoscopy and narrow band imaging for colonic neoplasms: a meta-analysis. The PTAs for a target of 50% of an 8 h dose interval, and for 70% of both 6 h and 8 h dose intervals were superior in the fed state. februari 2014 in opeenvolgende fasen zijn uitgevoerd. No, Is the Subject Area "Dose prediction methods" applicable to this article? 2011, 107: 659-667. The mean (90% CI) fed/fasting ratios of free concentrations exceeded for 30%, 50% and 70% of the first 6 hours post-dose were 0.74 (0.63–0.87, fed inferior p<0.01), 0.95 (0.81–1.11, bioequivalent) and 1.15 (0.97–1.36, fed non-inferior), respectively. WE has contributed to the protocol of the study, data extraction, data-analysis and wrote manuscript. The delaying effects of food on absorption, noted above, raised the possibility of a Tlag, and either an altered absorption rate constant (ka) with first-order absorption or a different mechanism of absorption such as zero-order. Non-compartmental pharmacokinetics of total and free flucloxacillin concentrations were calculated for each volunteer in each treatment phase using PKSolver on the Microsoft Office 2010 Excel platform [15]. As correctly mentioned in some of the reviews included in our study, little is known about the actual existence of selective publication of DTA studies [75]. An asymmetric funnel is an indication for publication bias. This may be associated with more upper gastrointestinal side effects and lead to some patients omitting doses around meal times and may be virtually unachievable in small children who often have variable eating patterns. The axes that were used to plot were diverse. 10.1111/j.1600-0447.2011.01730.x. 2012, 75: 242-253. Haldar P, Brightling CE, Singapuri A, et al. This method removes the most extreme small studies on the side of the desired outcome direction in the funnel plot, and recomputes the effect size at each iteration until the plot is symmetrical [17].

The majority of DTA review authors mention or investigate publication bias. For total plasma concentrations of flucloxacillin, the mean fed/fasting AUC0-∞ ratio of 0.84 was consistent with the ratio of 0.81 for the amount excreted in urine for 12 hours post-dose in fed versus fasting states (mean of 387 mg with food versus 476 mg in the fasting state). A subsequent study using the same dose had similar findings, with mean peak total serum concentrations of 6.2 mg/L at 3 hours after administration with food and 11.4 mg/L at 1 hour after administration on an empty stomach [6].
