Italy recorded its first case of confirmed acute respiratory case due to Coronavirus on February 18, 2020, soon after the initial reports in China. Since that time, Italy and nations throughout the world have adopted very stringent and severe measures to protect populations from spread of infection.Despite these measures, the number of infected people is growing exponentially with a significant number of patients developing acute respiratory insufficiency. Endoscopy departments face significant risk for diffusion of respiratory diseases that can be spread via an airborne route, including aspiration of oral and fecal material via endoscopes. The purpose of this article is to discuss the measures, with specific focus on personal protection equipment and dressing code modalities, which have been implemented in our hospital to prevent further dissemination of COVID-19 infection.

SET is a promising new technique for selected submucosal tumors in the esophagus and cardia up to a size of 4 cm and should be studied further.

In the present series the incidence of EE and of BE in SG patients was considerably higher than that reported in the current literature, and it was not related to GERD symptoms. Endoscopic surveillance after SG should be advocated irrespective of the presence of GERD symptoms.

Inflammation, oxidative stress and apoptosis, which are involved in chronic obstructive pulmonary disease (COPD) pathogenesis, may activate the p38 subgroup of mitogenactivated protein kinases (MAPKs). Therefore, the aim of the present study was to evaluate the expression of the phosphorylated, active form of p38 MAPK (phospho-p38) in the lungs of COPD patients.Surgical specimens were obtained from 18 smokers with COPD at different stages of disease severity, plus nine smoking and eight nonsmoking subjects with normal lung function. Phosphop38+ cells were quantified by immunohistochemistry in both alveolar spaces and alveolar walls. Moreover, a Western blot analysis of phospho-p38 and total p38a isoform expressed by alveolar macrophages was performed.Phospho-p38+ alveolar macrophages and phospho-p38+ cells in alveolar walls were increased in patients with severe and mild/moderate COPD, compared with smoking and nonsmoking controls. Moreover, they were inversely correlated to values of forced expiratory volume in one second (FEV1) and FEV1/forced vital capacity. Western blot analysis showed that phosphorylated p38, but not the total p38a isoform, was specifically increased in alveolar macrophages from COPD patients.Activation of the p38 mitogen-activated protein kinase pathway appears to be involved in the pathogenesis of chronic obstructive pulmonary disease. The present findings suggest that this protein may be a suitable pharmacological target for therapeutic intervention.

Recent advances in the knowledge of asthma pathobiology suggest that biological therapies that target cytokines can be potentially useful for the treatment of this complex and heterogeneous airway disease. The use of biologics in asthma has been established with the approval of the humanized monoclonal immunoglobulin E-targeted antibody omalizumab (Xolair; Genentech/Novartis) as an add-on treatment for inadequately controlled disease. Furthermore, evidence is accumulating in support of the efficacy of other biologics, such as interleukin-5 (IL-5)- and IL-13-specific drugs. Therefore, these new developments are changing the scenario of asthma therapies, especially with regard to more severe disease. The variability among patients' individual therapeutic responses highlights that it will be necessary to characterize the different asthma subtypes so that phenotype-targeted treatments based on the use of biologics can be implemented.
