Investigation of clinically acceptable agreement between two methods of automatic measurement of limb occlusion pressure: a randomised trial
Creators: name: Hughes, Luke

Publisher: name: BioMed Central
Year: 2021

description: Background: Development of automatic, pneumatic tourniquet technology and use of personalised tourniquet pressures has improved the safety and accuracy of surgical tourniquet systems. Personalisation of tourniquet pressure requires accurate measurement of limb occlusion pressure (LOP), which can be measured automatically through two different methods. The ‘embedded LOP’ method measures LOP using a dual-purpose tourniquet cuff acting as both patient sensor and pneumatic effector. The ‘distal LOP’ method measures LOP using a distal sensor applied to the patient’s finger or toe of the operating limb, using photoplethysmography to detect volumetric changes in peripheral blood circulation. The distal LOP method has been used clinically for many years; the embedded LOP method was developed recently with several advantages over the distal LOP method. While both methods have clinically acceptable accuracy in comparison to LOP measured using the manual Doppler ultrasound method, these two automatic methods have not been directly compared. The purpose of this study is to investigate if the embedded and distal methods of LOP measurement have clinically acceptable agreement. The differences in pairs of LOP measurement in the upper and lower limbs of 81 healthy individuals were compared using modified Bland and Altman analysis. In surgery, it is common for cuff pressure to deviate from the pressure setpoint due to limb manipulation. Surgical tourniquet systems utilise a ± 15 mmHg pressure alarm window, whereby if the cuff pressure deviates from the pressure setpoint by > 15 mmHg, an audiovisual alarm is triggered. Therefore, if the difference (bias) ± SE, 95% CI of the bias and SD of differences ± SE in LOP measurement between the embedded and distal methods were all within ±15 mmHg, this would demonstrate that the two methods have clinically acceptable agreement. Results: LOP measurement using the embedded LOP method was − 0.81 ± 0.75 mmHg (bias ± standard error) lower than the distal LOP method. The 95% confidence interval of the bias was − 2.29 to 0.66 mmHg. The standard deviation of the differences ± standard error was 10.35 ± 0.49 mmHg. These results show that the embedded and distal methods of LOP measurement demonstrate clinically acceptable agreement. Conclusions: The findings of this study demonstrate clinically acceptable agreement between the embedded and distal methods of LOP measurement. The findings support the use of the embedded LOP method of automatic LOP measurement using dual-purpose tourniquet cuffs to enable accurate, effective and simple prescription of personalised tourniquet cuff pressures in a clinical setting.

description: In this paper a double (or two-phase) sampling version of (Singh and Tailor, 2005) estimator has been suggested along with its properties under large sample approximation. It is shown that the estimator due to (Kawathekar and Ajgaonkar, 1984) is a member of the proposed class of estimators. Realistic conditions have been obtained under which the proposed estimator is better than usual unbiased estimator, usual double sampling ratio ( tRd ) product ( tPd ) estimators and (Kawathekar and Ajgaonkar, 1984) estimator. This fact has been shown also through an empirical study.

description: The concept of an output-driven map formally characterizes an intuitive notion about phonology: that disparities between the input and the output are introduced only to the extent necessary to satisfy restrictions on outputs. When all of the grammars definable in a phonological system are output-driven, the implied structure provides significant computational benefits to language learners. An output-driven map imposes significant structure on the space of possible inputs for words, which can allow a learner to efficiently learn a lexicon of phonological underlying forms despite the vast number of possible lexica, as well as contend with the challenges of map/lexicon interactions inherent in phonological learning. This article presents a learning algorithm that exploits the structure of output-driven maps, illustrated with a system of grammars based in Optimality Theory. The algorithm highlights the roles played by contrast and paradigmatic information in phonological learning.

description: The MIX computer system is a machine-independent software system, written in FORTRAN IV, giving users the ability to assemble and execute programs written for the MIX computer, as defined in D. E. Knuth in The Art of Computer Programming. The system consists of four essentially independent major subsystems: the control system, the interpreter, the assembler, and the loader. The system runs as a single job under the operating system of the host machine, but the system has its own control statements to allow batching of MIX jobs within a single host machine job.

description: BACKGROUND: Unplanned hospital readmissions are common adverse events. The LACE+ score has been used to identify patients at the highest risk of unplanned readmission or death, yet the external validity of this score remains uncertain. METHODS: We constructed a cohort of patients admitted to hospital between October 1, 2014 and January 31, 2017 using population-based data from British Columbia (Canada). The primary outcome was a composite of urgent hospital readmission or death within 30 days of index discharge. The primary analysis sought to optimize clinical utility and international generalizability by focusing on the modified LACE+ (mLACE+) score, a variation of the LACE+ score which excludes the Case Mix Group score. Predictive performance was assessed using model calibration and discrimination. RESULTS: Among 368,154 hospitalized individuals, 31,961 (8.7%) were urgently readmitted and 5,428 (1.5%) died within 30 days of index discharge (crude composite risk of readmission or death, 9.95%). The mLACE+ score exhibited excellent calibration (calibration-in-the-large and calibration slope no different than ideal) and adequate discrimination (c-statistic, 0.681; 95%CI, 0.678 to 0.684). Higher risk dichotomized mLACE+ scores were only modestly associated with the primary outcome (positive likelihood ratio 1.95, 95%CI 1.93 to 1.97). Predictive performance of the mLACE+ score was similar to that of the LACE+ and LACE scores. CONCLUSION: The mLACE+, LACE+ and LACE scores predict hospital readmission with excellent calibration and adequate discrimination. These scores can be used to target interventions designed to prevent unplanned hospital readmission.

description: This paper aims to outline the development of Statistics from 1861 to 1981 with respect to its contents. The paper pays particular attention to some statistical topics which have been covered by basic introductory courses in the Italian Universities since the beginning of the Italian unification. The review takes as its starting point the well-known book “Filosofia della Statistica” of Melchiorre Gioja. This volume was published 35 years before Italian unification but it already contains the fundamental topics of exploratory and inductive Statistics. These topics give the opportunity to mention Italian statisticians who are considered the pioneers of this discipline. In particular, the attention is focused on four statisticians: Corrado Gini, well-known for its modern insights; Marcello Boldrini, high cultured man also in the epistemological field; Bruno de Finetti, founder of subjective school and Bayesian reasoning; Giuseppe Pompilj, precursor of random variables and sampling theory. The paper browses the indexes of three well-known Italian handbooks that, although published after the period 1861-1981, deal with topics covered in some basic teachings of exploratory statistics, statistical inference and sampling theory from finite population.

description: On the basis of some characteristics such as quantile function and skewness coefficient of n th upper/lower record of a given absolutely continuous distribution, as well as a confidence interval for nth upper/lower record statistic of a two-parameter Weibull model, a point estimator for shape parameter of this family also is given. Furthermore, behavior of the skewness coefficient of nth upper/lower record statistic of this family is discussed. Tabulation of the confidence interval of the nth upper/lower record statistics of this family for some levels of confidence and parameters is useful for predicting the future nthupper/lower record. The performance of the given shape estimator is measured through a simulated data set comparison with the maximum likelihood estimation. Also, skewness analysis of the nth upper/lower record statistic is useful for estimating the nth upper/lower record statistic of this family as it will be discussed.

description: CUB models represent a new approach for the analysis of categorical ordinal data. The relevant domain of study is the specification and estimation of the behaviour of respondents when faced to ratings by analysing the relationship among ordinal scores and observed covariates. The increasing use of such models suggests to delve into the issue of appropriate residuals to be used for diagnostic purposes. In fact, the discreteness of the response variable discourages the use of standard regression paradigms. In this context, we propose the extension and implementation of a specific graphical methodology, known as binned residual plots, in order to check the adequacy of fitted CUB models and/or infer about improvements of the maintained model. Such proposals have been exemplified through the analysis of real data.

description: Empirical studies show that misspecification of the married (or cohabiting) women’s labour supply equation may produce inefficient wage-elasticity estimates. In order to reduce the variability of these estimates, we suggest a new approach based on instrumental variables given by the economic value of the domestic unpaid-work of women. Using Italian micro-data on time use (ISTAT Survey on Time Use), and applying both a parametric and a semiparametric procedure, we estimate robust wage-elasticity coefficients of married women’s labour supply. Our results suggest that women’s labour supply is negatively influenced by the indirect cost of their informal activity of childcare and domestic work.

description: The integrated extinction (IE) is defined as the integral of the scattering cross-section as a function of wavelength. Sohl et al. [1] derived an IE expression for acoustic scattering that is causal, i.e. the scattered wavefront in the forward direction arrives later than the incident plane wave in the background medium. The IE formula was based on electromagnetic results, for which scattering is causal by default. Here we derive a formula for the acoustic IE that is valid for causal and non-causal scattering. The general result is expressed as an integral of the time dependent forward scattering function. The IE reduces to a finite integral for scatterers with zero long-wavelength monopole and dipole amplitudes. Implications for acoustic cloaking are discussed and a new metric is proposed for broadband acoustic transparency.

We introduce and study the properties of a new distribution called geometric generalized discrete Mittag-Leffler distribution. Autoregressive processes with geometric generalized discrete Mittag-Leffler distributions are developed and studied. The distributions are further extended to develop a more general class of geometric generalized discrete semi-Mittag-Leffler distributions. The processes are extended to higher orders also. An application with respect to an empirical data on customer arrivals in a bank counter is also given. Various areas of potential applications like human resource development, insect growth, epidemic modeling, industrial risk modeling, insurance and actuaries, town planning etc are also discussed.

Index and prevision of satisfaction in exponential models for clinical trials
Creators: name: Merabet, H.
Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna
Year: 2007

description: This paper deals with a Bayesian predictive approach applied to a frequentist statistical test. The methodology is useful in two-steps testing procedures, such as those considered in the clinical trial context. We review the Bayesian predictive procedure for monitoring experiments and the notion of index of satisfaction. We applied this procedure to a family of limited indices of satisfaction. These indices generalize the rudimentary index of satisfaction considered by Grouin (1994) and the interest of these indices of satisfaction could be in the concept of ‘‘prevision of satisfaction’’ for a future sample, given the data in hand. Given the posterior distribution derived from the available data, the ‘‘prevision of satisfaction’’ is defined like the predictive expectation of the index of satisfaction for the future sample (the interpretation of the index being left to the ‘‘expert’’). The procedure is introduced in the case of a two-step trial, where the result of the first step is used to decide if the experiment will be continued. We consider different cases of the application of the proposed procedure with a conjugate prior. The computations and the simulation results concern an inferential problem, related to the Gaussian model.

description: The use of Gini’s mean difference as an index of variability has, until now, been restricted because of some difficulties arising in computing and estimating the variance of its estimator d. The aim of this paper is to cope with these issues. Considering the mean deviation D(x) of a r.v. X about a given value x, the Gini’s mean difference d results to be the expected value of D(x). Moreover, denoting by f the expected value of D2(x) and by d the sample mean difference without repetition, Var(d) can be expressed as a function of the variance of X, say s2, d and f.
Two estimators for Var(d) are obtained: starting from the natural estimator, whose asympthotic unbiasedness is shown, an unbiased estimator is then derived.

description: This paper examines whether sales promotions effectiveness depends upon the consumer’s brand loyalty and her buying behaviour and whether consumer’s behavioural characteristics in term of purchase frequency and level affect the response to promotional activities and moderate the effect of brand loyalty during the consumer choice process. Different specifications for the utility function, exploiting information on selling price, promotional activities such as displays usage, ad features in the store, 3x2 and discount, and differently brand loyalty measures have been estimated into a discrete choice framework, that is into the rational brand choice paradigm, paying attention to their effects on individuals’ probabilities to choose the specific brand during each purchase occasion. The application is run on a ACNielsen dataset of Italian households consumer panel, observed to buy at least two yoghurt packages during a year, matched to store panel data with respect to quantities, prices and promotions.

description: A significant change in the Western diet, concurrent with the obesity epidemic, was a substitution of saturated fatty acids with polyunsaturated, specifically linoleic acid (LA). Despite increasing investigation on type as well as amount of fat, it is unclear which fatty acids are most obesogenic. The objective of this study was to determine the obesogenic potency of LA vs. saturated fatty acids and the involvement of hypothalamic inflammation. Forty-eight mice were divided into four groups: low-fat or three high-fat diets (HFDs, 45% kcals from fat) with LA comprising 1%, 15% and 22.5% of kilocalories, the balance being saturated fatty acids. Over 12 weeks, bodyweight, body composition, food intake, calorimetry, and glycemia assays were performed. Arcuate nucleus and blood were collected for mRNA and protein analysis. All HFD-fed mice were heavier and less glucose tolerant than control. The diet with 22.5% LA caused greater bodyweight gain, decreased activity, and insulin resistance compared to control and 1% LA. All HFDs elevated leptin and decreased ghrelin in plasma. Neuropeptides gene expression was higher in 22.5% HFD. The inflammatory gene Ikk was suppressed in 1% and 22.5% LA. No consistent pattern of inflammatory gene expression was observed, with suppression and augmentation of genes by one or all of the HFDs relative to control. These data indicate that, in male mice, LA induces obesity and insulin resistance and reduces activity more than saturated fat, supporting the hypothesis that increased LA intake may be a contributor to the obesity epidemic.

description: Future ubiquitous computing environments will consist of massive, ad hoc networks of embedded systems deployed in the physical space. Programming such environments requires new abstractions and computing models. This paper presents Spatial Programming (SP), a novel paradigm for programming ubiquitous computing environments. SP offers access to data and services distributed on nodes spread across the physical space in a similar fashion to access to memory using references. SP programs access network resources using a high level abstraction, termed spatial reference, which names these resources using their spatial properties and content-based names. An underlying system takes care of mapping spatial references onto target nodes in the network. Thus, SP hides the complexity of the underlying network from the programmer, while offering a simple and intuitive programming.
Long-term survivors in an epidemic without recovery
Creators: name: Schinaia, G.
Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna
Year: 2007

description: The analysis of epidemics without recovery often implies the inclusion of long-term survivors in the modeling process. Such individuals are characterized by a peculiarly long sojourn in a state of infection without any sign of progression towards the subsequent evolutionary state of the disease. A parametric modeling of their presence in an epidemic involves non-Markov staging of the infection process and of its development. In the present work, an approach involving survivor function is proposed, along with some remarks on epidemiological indicators and some numerical and graphical examples of its application.

Year: 2007

description: Three separate estimators, for the estimation of the population total, based on two-stage sampling design on two successive occasions with partial replacement of secondary stage units only have been presented. For these estimators it is assumed that there is unit non-response. Hence, Hansen and Hurwitz (1946) technique has been used to adjust for the non-response. Empirically, it has been found that the estimator that uses individual weights within first stage units perform better than the other estimators that use common weights in estimating the population total. Theoretically, it has also been shown that the larger the ratio of the within first stage unit variability of the non-respondents to the between first stage unit variability the higher the gain in efficiency of the proposed estimators over the estimator obtained when there is no partial matching of units.

Conserving disk energy in network servers

Year: 2002

description: In this paper we study four approaches to conserving disk energy in high-performance network servers. The first approach is to leverage the extensive work on laptop disks and power disks down during periods of idleness. The second approach is to replace high-performance disks with a set of lower power disks that can achieve the same performance and reliability. The third approach is to combine high-performance and laptop disks, such that only one of these two sets of disks is powered on at a time. This approach requires the mirroring (and coherence) of all disk data on the two sets of disks. Finally, the fourth approach is to use multi-speed disks, such that each disk is slowed down for lower energy consumption during periods of light load. We demonstrate that the fourth approach is the only one that can actually provide energy savings for network servers. In fact, our results for Web and proxy servers show that the fourth approach can provide energy savings of up to 23%, in comparison to conventional servers, without any degradation in server performance.

description: An n n matrix with nonnegative entries is said to be balanced if for each i = 1,...., n, the sum of the entries of its i-th row is equal to the sum of the entries of its i-th column. An n n matrix A with nonnegative entries is said to be balanceable via diagonal similarity scaling if there exists a diagonal matrix X with positive diagonal entries such that XAX1 is balanced. We give upper and lower bounds on the entries of X and prove the necessary sensitivity analysis in the required accuracy of the minimization of an associated convex programming problem. These results are used to prove the polynomial time solvability of computing X to any prescribed accuracy.

The project aims to develop options to improve the (implementation of) the REACH regulation by analysing various REACH processes and related issues, including substitution, sustainable chemistry, precautionary principle, articles, cost-benefit analyses, socio-economic analyses and financing ECHA. The study analysed all steps of the authorisation processes with the aim of identifying options to increase the effectiveness and efficiency of the process. Based on a literature analysis and an assessment of example cases, it is concluded that the aims of authorisation are generally achieved. Nevertheless, several improvement options are identified amongst others regarding the selection of the process as risk management option, the availability of use information or the time-lines for processing and decision making on an application for authorisation.

description: The authorisation process is a central instrument of ⁠REACH⁠, aiming at reducing risks from the use of Substances of Very High Concern (SVHC). The goal is a stepwise elimination of such substances from the market with the option to grant temporary exemptions. The authorisation process comprises the identification of SVHCs for the candidate list, prioritisation Annex XIV, applications for authorisations (AfA), and the decision-making on granting. This project analysed the different steps by means of a literature analysis and an assessment of cases and proposes options to enhance the effectiveness and efficiency of the authorisation process.

description: Through a series of structured interviews, university librarians at six institutions provided their perspectives on innovation in academic libraries. The literature on leadership styles and organizational change provides insight into the roles of these leaders in the innovation process. Leadership is cited by many researchers as being a critical factor for organizations to innovate. In this study, university librarians’ perspectives reveal a commitment to innovation, some distinctively non-traditional innovations, and a concern for how to encourage risk-taking behavior. The study also seeks further insight into the innovation process by interpreting the interview data within a larger theoretical context. Although leadership and management can foster innovation in a library, researchers have reported other factors that can influence the ability to innovate, including organizational aspects – size and complexity – and environmental factors. Beyond the organizational aspects, the individual and the norms of the profession create a framework with certain boundaries, some of which may impact the ability to innovate.
A Critical Review of the Time-Dependent Performance of Polymeric Pipeline Coatings: Focus on Hydration of Epoxy-Based Coatings

description: The barrier performance of organic coatings is a direct function of mass transport and long-term stability of the polymeric structure. A predictive assessment of the protective coating cannot be conducted a priori of degradation effects on transport. Epoxy-based powder coatings are an attractive class of coatings for pipelines and other structures because application processing times are low and residual stresses between polymer layers are reduced. However, water ingress into the polymeric network of these coatings is of particular interest due to associated competitive sorption and plasticization effects. This review examines common analytical techniques for identifying parameters involved in transport in wet environments and underscores the gaps in the literature for the evaluation of the long-term performance of such coating systems. Studies have shown that the extent of polymer hydration has a major impact on gas and ion permeability/selectivity. Thus, transport analyses based only on micropore filling (i.e., adsorption) by water molecules are inadequate. Combinatorial entropy of the glassy epoxy and water vapor mixture not only affects the mechanism of membrane plasticization, but also changes the sorption kinetics of gas permeation and causes a partial gas immobility in the system. However, diffusivity, defined as the product of a kinetic mobility parameter and a concentration-dependent thermodynamic parameter, can eventually become favorable for gas transport at elevated temperatures, meaning that increasing gas pressure can decrease selectivity of the membrane for gas permeation. On the other hand, reverse osmosis membranes have shown that salt permeation is sensitive to, among other variables, water content in the polymer and a fundamental attribute in ionic diffusion is the effective size of hydrated ions. In addition, external electron sources—e.g., cathodic protection potentials for pipeline structures—can alter the kinetics of this transport as the tendency of ions to dissociate increases due to electrostatic forces. Focusing primarily on epoxy-based powder coatings, this review demonstrates that service parameters such as humidity, temperature, and concentration of aggressive species can dynamically develop different transport mechanisms, each at the expense of others. Although multilayered coating systems decrease moisture ingress and the consequences of environmental exposure, this survey shows that demands for extreme operating conditions can pose new challenges for coating materials and sparse data on transport properties would limit analysis of the remaining life of the system. This knowledge gap impedes the prediction of the likelihood of coating and, consequently, infrastructure failures.

description: Broad and detailed knowledge about common species in everyday life has decreased among the public. Even biology researchers may be largely unaware of our everyday biodiversity. To counter such 'species blindness' and create long-term excitement and learning about the biodiversity we see every day, we arranged 76-day BioBlitzes at Rutgers University (New Jersey, USA) in 2014 and 2015 where participants identified and listed all species they discovered. The result was 7270/11748 observations from 30/78 participants and 7/13 countries, including 3458/3057 unique taxa, 91%/99.9% identified to species and 80%/54% listed only by one person (2014/2015). Observations of organismal groups did not strongly correspond to number of estimated species worldwide, but appeared to be related to perceived charisma, body size, and organism mobility. Participants reported increased ability to 'see' species and to identify new groups, learning new tools of species identification and strongly increasing their biodiversity knowledge and eagerness to learn more.

description: The paper presents a statistical methodology able to evaluate European Monetary Union in effects on international financial flows. Foreign direct investment and portfolio investment, interpreted as indicators of growth expectations, are analyzed in order to detect if Euro introduction represents a source of economic integration among EMU countries. By referring to risk sharing methods, portfolio investment flows are founded to be a risk sharing cannel, while direct investment flows increase consumption variability.

Lecture Notes on the New AKS Sorting Network

description: Ajtai, Komlós, and Szemerédi constructed sorting networks with N wires of depth O(logN). They were not concerned with the value of the proportionality constant implicit in the O-notation; subsequently Paterson replaced the O(logN) by c log2 N with c under 6100. We describe an implementation of a more recent, and as yet unpublished, proposal of Ajtai, Komlós, and Szemerédi, that yields a smaller value of c: for every integer N such that N >= 2^78 there is a sorting network on N wires whose depth is at most 1830 log2 N - 58657. The basic units in this new construction are sorting networks on M wires such that M is relatively small; these may be thought of as indivisible hardware elements (rather than networks made from comparators); following Knuth, we call them M-sorters. For every choice of positive integers M and N such that N >= M, the construction yields a sorting network on N wires, made from M-sorters, whose depth is at most (48 + o(1)) logM N + 115 as M --> ∞. (It is worth emphasizing that the asymptotic o(1) here is relative to M rather than N.)

description: We describe Mendosus, a SAN-based fault-injection test-bed that supports the emulation of LAN-based systems. Our goal is to provide a test-bed for service designers to systematically assess the impact of end-to-end design decisions on the availability and reliability of network services in the presence of realistic fault scenarios. As such, our current implementation is just a first step toward this vision; currently, we are working to extend Mendosus to be able to emulate a rich set of networks, including wireless systems and WAN-connected systems. An emulator must work in real-time, providing a platform that looks and performs as similar to the deployed platform as possible; Mendosus relies critically on the high performance of the underlying SAN system to achieve this goal. Preliminary measurements show that we should easily be able to emulate 100 Mb/s and 1 Gb/s Ethernet LANs using our VIA-based implementation.

description: Ginkgo biloba L. has attracted much attention due to its medicinal properties, particularly those of its terpenoid and flavonoid contents. However, the content and utilization efficiency of terpenoids remain low. The enzyme 3-hydroxy-3-methylglutaryl CoA synthase (HMGS) is a major rate-limiting factor, and RNA-seq has revealed that the mRNA expression of this enzyme is differentially expressed during terpenoid biosynthesis. Here, we investigated the function of the GbHMGS1 gene and its overexpression in Populus. We compared the metabolite contents of nontransgenic (CK) Populus with those of transgenic Populus lines through metabolomics analysis. Our results indicate that the GbHMGS1 protein is localized in the cytoplasm. Significant differences in chemical characteristics were found between the transgenic and CK plants, and a total of 31 differentially expressed metabolites were upregulated in the transgenic plants. We also found higher contents of lanosterol (triterpenoid), dehydroabietic acid (diterpenoid), and phytol (diterpenoid) in the transgenic Populus plants than in their CK counterparts. We thus speculate that GbHMGS1 might regulate plant-related product formation and increase metabolite contents. This study revealed the molecular mechanism governing metabolite synthesis and suggested that one triterpenoid and two diterpenoids with significant upregulation can be used as markers for the breeding of plants with specific terpenoid metabolism-related characteristics.
