Diagnostics for meta-analysis based on generalized linear mixed models

2012

Meta-analysis is the method to combine data coming from multiple studies, with the aim to provide an overall event-risk measure of interest summarizing information coming from the studies. In meta-analysis generalized linear mixed models (GLMM) are particularly used for a number of measures of interest since they allow the true effect size to differ from study to study while accepting binary, discrete as well as continuous response variable. In the present paper some strategies of influence diagnostics based on log-likelihood are suggested and discussed. These are considered for Individual Patient Data, Aggregate Data and their compounding.

The effectiveness of leadership: meta-analysis of trial, cross-sectional, and before after studies

2020

Abstract Background The clinical and surgical procedures are often based on scientifical evidence but 30-40% of patients do not receive treatment according to evidence based medicine. The main aim of this review and meta-analysis is to assess the effectiveness of leadership in healthcare setting. Methods It was conducted a literature research on MEDLINE, Pubmed and Scopus with publication year between 2015 and 2019. The inclusion criteria were studies involving healthcare workers that evaluated effectiveness of opinion leaders in improving behaviour of healthcare workers, according to clinical or patient related outcomes. The quality of studies were assesed with the NHLBI for before after s…

L'analyse statistique du profil sensoriel revisitée par une approche base de données

2015

During a sensory evaluation, trained subjects taste and score products on differentdescriptors in order to obtain a descriptive profile of these products. The data are thenanalyzed by several statistical methods (PCA, ANOVA…) in order to monitor the subjectperformances and map the product space.This work aims to revisit these statistical methods thanks to the analysis of a large number ofdatasets of sensory profiling data from the SensoBase (a database containing more than athousand of datasets). Different statistical methods of mapping and analysis ofperformances were compared, then improved. We mainly focused on the so-called scalingeffect (tendency of the subject to spread his scores mor…

Meta-metafisica?

2019

Collection of essays on "meta-metaphysics".

2014

This paper investigates an evolutionary-based designing system for automated sizing of analog integrated circuits (ICs). Two evolutionary algorithms, genetic algorithm and PSO (Parswal particle swarm optimization) algorithm, are proposed to design analog ICs with practical user-defined specifications. On the basis of the combination of HSPICE and MATLAB, the system links circuit performances, evaluated through specific electrical simulation, to the optimization system in the MATLAB environment, for the selected topology. The system has been tested by typical and hard-to-design cases, such as complex analog blocks with stringent design requirements. The results show that the design specifica…

Metafisica si dice in molti modi. Sulla recente Storia della metafisica a cura di Enrico Berti

2020

Is it possible to recount the history of metaphysics? And what image of metaphysics can emerge from this historyand from the narration of such a history? The recent volume Storia della metafisica, edited by Enrico Berti and at the coreof the analysis of the present essay, helps us to answer these questions,confirming that metaphysics is said in many ways.

Bloodstream Infections in Hospitalized Patients with COVID-19: A Systematic Review and Meta-Analysis

2021

Background: Little is known about the occurrence of bloodstream infections in hospitalized patients with COVID-19 and the related clinical consequences. The aim of this systematic review and meta-analysis was to estimate the pooled occurrence of BSIs among hospitalized patients with COVID-19 and mortality of this patient population. Methods: A systematic search was performed on PubMed, EMBASE, and Web of Science from inception to 19 April 2021. The primary outcome was the occurrence of BSIs among hospitalized patients with COVID-19. The secondary outcome was mortality at the longest available follow-up. Results: Forty-six studies met the inclusion criteria, with a total of 42,694 patients e…
