Laboratory testing in the emergency department: an Italian Society of Clinical Biochemistry and Clinical Molecular Biology (SIBioC) and Academy of Em…
2018
Abstract Background: The mainstay of patient-oriented laboratory testing in emergency settings entails selecting a number and the type of tests according to valid criteria of appropriateness. Since the pattern of urgent tests requesting is variable across different institutions, we designed a joined survey between the Academy of Emergency Medicine and Care (AcEMC) and the Italian Society of Clinical Biochemistry and Clinical Molecular Biology (SIBioC) for reaching tentative consensus about the most informative diagnostic tests in emergency settings. Methods: A survey, containing the most commonly ordered urgent laboratory tests and the relative clinical indications, was disseminated to eigh…
Characterization of Gut Microbiota Composition in Type 2 Diabetes Patients: A Population-Based Study.
2022
(1) Background: A clinical laboratory index to assess gut dysbiosis is the F/B ratio < 0.8. In fact, an elevated proportion of Firmicutes and a reduced population of Bacteroides in diabetes type 2 (T2D) subjects has been observed. This study aimed to detail the dysbiosis status in the Italian population, focusing on some pathogenic spectra (T2D) or metabolic disorders. (2) Material and methods: A quantity of 334 fecal samples was analyzed in order to perform genetic testing and sequencing. (3) Results: A trend in over imbalance was observed in the percentage of Proteobacteria (median value: 6.75%; interquartile range (IQR): 3.57–17.29%). A statistically significant association (&ch…
A Hazelnut-Enriched Diet Modulates Oxidative Stress and Inflammation Gene Expression without Weight Gain
2019
Introduction. Inflammation is associated with obesity condition and plays a pivotal role in the onset and progression of many chronic diseases. Among several nutraceutical foods, hazelnuts (Corylus avellana L.) are considered an excellent anti-inflammatory and hypolipidemic food being the second richest source of monounsaturated fatty acids among nuts and because they are rich in vitamins, minerals, and phenolic compounds. Materials and Methods. A prospective pilot clinical trial on 24 healthy volunteers who consumed daily, as a snack, 40 g of hazelnuts (261.99 kcal/1096.17 kJ) for six weeks was conducted. Anthropometric measurements, body composition analysis, and nutrigenomic analysis on …
Glycated albumin is correlated to insulin resistance and β-cell secretory function in subjects at risk for developing diabetes
2018
Insulin resistance and β-cell secretory function represent two main issues in the pathogenesis of type 2 diabetes mellitus (T2DM). Conflicting results have been obtained about the association between glycated albumin (GA) and body mass index (BMI), insulin resistance and β-cell function in diabetic patients. Actually, the relationship (if any) between GA and the markers of glucose homeostasis and insulin resistance in subjects at risk of developing diabetes, has not been completely elucidated yet. Two hundred and one patients undergoing to oral glucose tolerance test (OGTT) were enrolled in the study. Routine laboratory tests, including fasting insulin, were performed at enrollment. GA was …
Head-to-head comparison of plasma cTnI concentration values measured with three high-sensitivity methods in a large Italian population of healthy vol…
2019
Abstract Background The study aim is to compare cTnI values measured with three high-sensitivity (hs) methods in apparently healthy volunteers and patients admitted to emergency department (ED) with acute coronary syndrome enrolled in a large multicentre study. Methods Heparinized plasma samples were collected from 1511 apparently healthy subjects from 8 Italian clinical institutions (mean age: 51.5 years, SD: 14.1 years, range: 18–65 years, F/M ratio:0.95). All volunteers denied chronic or acute diseases and had normal values of routine laboratory tests. Moreover, 1322 heparinized plasma sample were also collected by 9 Italian clinical institutions from patients admitted to ED with clinica…
Improvement of ALT decay kinetics by all-oral HCV treatment: Role of NS5A inhibitors and differences with IFN-based regimens
2017
Background Intracellular HCV-RNA reduction is a proposed mechanism of action of direct-acting antivirals (DAAs), alternative to hepatocytes elimination by pegylated-interferon plus ribavirin (PR). We modeled ALT and HCV-RNA kinetics in cirrhotic patients treated with currently-used all-DAA combinations to evaluate their mode of action and cytotoxicity compared with telaprevir (TVR)+PR. Study design Mathematical modeling of ALT and HCV-RNA kinetics was performed in 111 HCV-1 cirrhotic patients, 81 treated with all-DAA regimens and 30 with TVR+PR. Kinetic-models and Cox-analysis were used to assess determinants of ALT-decay and normalization. Results HCV-RNA kinetics was biphasic, reflecting …
Raccomandazioni ad interim di SIBioC per l’analisi sierologica dell’infezione da SARS-CoV-2
2021
The recent pandemic outbreak caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and associated with the pathology called COVID-19 (coronavirus disease 2019), has now become one of the most strenuous health care challenges since the emergence of the three pandemics caused by influenza viruses during the past century. Throughout the clinical decision-making of COVID-19, laboratory tests are essential for supporting the screening, diagnosis, prognostication and therapeutic monitoring of this severe infectious disease. Serological testing, that reflects the humoral immune response developing after interaction between the host and the virus (or its components), enables to…
Esami di laboratorio in Pronto Soccorso: una proposta di consenso SIBioCMedicina di Laboratorio e Academy of Emergency Medicine and Care
2017
Laboratory diagnostics in the emergency setting encompasses the identification of appropriate testing according to specific acute conditions. Since the pathway of ordering tests in the Italian Emergency Departments (EDs) is rather heterogeneous, SIBioC-Medicina di Laboratorio and the Academy of Emergency Medicine and Care designed a survey aimed to generate consensus pertaining to appropriate laboratory tests in most frequent acute conditions. A questionnaire including a panel of laboratory tests was administered to 8 representative members of each of the two societies, who were asked to provide a score between 1 and 3 for the various tests, where a score of 1 entailed "highly recommended",…
