Comparison of Adverse Effects of Two SARS-CoV-2 Vaccines Administered in Workers of the University of Padova.

: In Italy, on December 2020, workers in the education sector were identified as a priority population to be vaccinated against COVID-19. The first authorised vaccines were the Pfizer-BioNTech mRNA (BNT162b2) and the Oxford-AstraZeneca adenovirus vectored (ChAdOx1 nCoV-19) vaccines. : To investigate the adverse effects of two SARS-CoV-2 vaccines in a real-life preventive setting at the University of Padova.

Bio-Engineered Scaffolds Derived from Decellularized Human Esophagus for Functional Organ Reconstruction.

Esophageal reconstruction through bio-engineered allografts that highly resemble the peculiar properties of the tissue extracellular matrix (ECM) is a prospective strategy to overcome the limitations of current surgical approaches. In this work, human esophagus was decellularized for the first time in the literature by comparing three detergent-enzymatic protocols. After decellularization, residual DNA quantification and histological analyses showed that all protocols efficiently removed cells, DNA (<50 ng/mg of tissue) and muscle fibers, preserving collagen/elastin components.

Laparoscopic Heller-Dor is an effective long-term treatment for end-stage achalasia.

Background: The end-stage achalasia is a difficult condition to treat, for the esophageal diameter and conformation of the gullet, that may progress to a sigmoid shape. The aim of this study was to examine the outcome of Laparoscopic Heller-Dor in patients with end-stage achalasia, comparing them with patients who had mega-esophagus without a sigmoid shape.

Methods: From 1992 to 2020, patients with a diagnosis of sigmoid esophagus, or radiological stage IV achalasia (the SE group), and patients with a straight esophagus larger than 6 cm in diameter, or radiological stage III achalasia (the NSE group), were all treated with LHD.

Multimodal treatment of radiation-induced esophageal cancer: Results of a case-matched comparative study from a single center.

Purpose: Radiation-induced esophageal cancer (RIEC) is a rare but severe late consequence of radiotherapy. The literature regarding this topic is predominately limited in describing the risk of this disease. Tumor behavior, treatment strategies, and prognosis of this cancer remain poorly defined.

Association of CLDN18 Protein Expression with Clinicopathological Features and Prognosis in Advanced Gastric and Gastroesophageal Junction Adenocarcinomas.

The tight junction protein claudin-18 (CLDN18), is often expressed in various cancer types including gastric (GC) and gastroesophageal adenocarcinomas (GECs). In the last years, the isoform CLDN18.2 emerged as a potential drug target in metastatic GCs, leading to the development of monoclonal antibodies against this protein.
