Exploratory data analysis Listeria monocytogenes in dairy production process: an exploration of available data
Due to the insufficient qualitative data of Listeria monocytogenes in production environment, this study
was aimed to evaluate the possibility to extract from a historical database useful information about
the occurrence of Listeria monocytogenes in different production process areas. Estimated probabilities
(p) and confidence limit (CL) were calculated using 3276 environmental samples data analysed
by GLMM model. The attempt to use historical data to estimate the occurrence of Listeria monocytogenes
in processing environment leads for some areas to high p value wide CL. The results suggest
the need for a targeted environmental sampling plan and provides some estimate sampling size

Critical assessment of the diagnostic value of feline alpha1-acid glycoprotein for feline infectious peritonitis using likelihood ratios approach
Alpha-1-acid glycoprotein (AGP) increases in the blood of cats with feline infectious peritonitis (FIP), a lethal disease caused by feline coronavirus (FCoV). However, the diagnostic potential of AGP might be limited because AGP also increases in pathophysiological conditions other than FIP. In this retrospective study, the diagnostic potential of serum AGP concentration was evaluated on the basis of the pretest probability of disease, according to the Bayesian approach. Serum AGP levels from cats with FIP (group 1; n = 58) and without FIP (group 2; n = 104) were evaluated. Non-FIP cats were further subgrouped as follows: 2a) inflammation (n = 26), 2b) asymptomatic FCoV infection (n = 49), 2c) injection-site sarcoma (n = 19), 2d) postvaccination (n = 7), and 2e) specific pathogen free (n = 3). Standard descriptive analyses by group and empirical receiver-operating characteristic (ROC) curve estimation were performed. Ordinary logistic regression analysis was performed to derive an estimate of the continuous likelihood ratio to produce the posttest probability of disease for any combination of pretest probability and serum AGP value. The comparison of serum AGP levels in the different groups and the analysis of the ROC curve confirmed that serum AGP is a powerful discriminating marker for FIP. The Bayesian approach demonstrated that when the pretest probability of FIP is high, based on history and clinical signs (groups 1 or 2a), moderate serum AGP levels (1.5-2 mg/ml) can discriminate cats with FIP from others, while only high serum AGP levels (>3 mg/ml) can support a diagnosis of FIP in cats with a low pretest probability of disease (groups 2b to 2e)
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Determinazione del valore di troponina I nel cane cardiopatico
Our preliminary research showed that cTnI is not correlated with age, sex and weight, but with an increased ESVI (index of a deficit in contractility) and EDVI (index of volume over-load); the variability of the enzyme in ISACHC classification needs to be study more; cTnI level appears interesting in examining the follow-up of patient with cardiac disease, especially cardiomyopathy
