Reference values of blood cell counts in the first days of life
The lack of updated neonatal reference values for hematological parameters impacts significantly with clinical management of both healthy and sick newborns. The present pilot study was thus aimed at assessing updated hematological Italian reference values in late preterm and term newborns. From January 2004 to December 2008 hematological laboratory tests were performed in 1175 newborns (820 healthy and 355 sick controls) between 33-41 weeks of gestation, during the first four days after birth. Hematological parameters were sorted for gender and gestational age and statistically analyzed. No gender-related differences were observed at different weeks of gestation and no significant differenc…

Cabbage and fermented vegetables: from death rate heterogeneity in countries to candidates for mitigation strategies of severe COVID-19
International audience; Large differences in COVID-19 death rates exist between countries and between regions of the same country. Some very low death rate countries such as Eastern Asia, Central Europe, or the Balkans have a common feature of eating large quantities of fermented foods. Although biases exist when examining ecological studies, fermented vegetables or cabbage have been associated with low death rates in European countries. SARS-CoV-2 binds to its receptor, the angiotensin-converting enzyme 2 (ACE2). As a result of SARS-CoV-2 binding, ACE2 downregulation enhances the angiotensin II receptor type 1 (AT1 R) axis associated with oxidative stress. This leads to insulin resistance …
Chronic obstructive lung disease “expert system”: Validation of a predictive tool for assisting diagnosis
Purpose: The purposes of this study were development and validation of an expert system (ES) aimed at supporting the diagnosis of chronic obstructive lung disease (COLD). Methods: A questionnaire and a WebFlex code were developed and validated in silico. An expert panel pilot validation on 60 cases and a clinical validation on 241 cases were performed. Results: The developed questionnaire and code validated in silico resulted in a suitable tool to support the medical diagnosis. The clinical validation of the ES was performed in an academic setting that included six different reference centers for respiratory diseases. The results of the ES expressed as a score associated with the risk of su…
