Is there a difference between GBS triggered by COVID-19 and those of other origins?

Background: Since the outbreak of the coronavirus disease 2019 (COVID-19), an increasing number of Guillain-Barré syndrome (GBS) cases following the infection has been reported. The aim of our study was to detect patients with GBS treated in our hospital over a 1-year period and to compare the characteristics and outcomes of those triggered by COVID-19 with the rest of GBS patients. Our prospective study included 29 patients who were diagnosed with GBS from March 2020 to March 2021.

Rate of progression of Guillain-Barré syndrome is not associated with the short-term outcome of the disease.

Introduction: There are no many data on association between progression rate of Guillain-Barré syndrome (GBS) and disease outcome.

Aim: The aim of our study was to analyze short-term outcome of GBS in relation to the rate of disease progression.

Methods: Our retrospective study included patients diagnosed with GBS in seven tertiary healthcare centers from 2009 to 2014.

Disability and quality of life in Guillain-Barré syndrome - Longitudinal study.

Longitudinal health-related quality of life (QoL) data in Guillain-Barré (GBS) patients are still scarce. We, therefore, investigated health- related QoL in GBS patients from Serbia and surrounding countries during a six-month follow-up period, and analyzed its association with patients' disability. Our study comprised 74 adult patients diagnosed with GBS from May 2017 until May 2018 in seven tertiary healthcare centers.

Congenital esophageal stenosis: a rare malformation of the foregut.

Congenital esophageal stenosis (CES) is a type of esophageal stenosis, and three histological subtypes (tracheobronchial remnants, fibromuscular thickening or fibromuscular stenosis, and membranous webbing or esophageal membrane) are described. Symptoms of CES usually appears with the introduction of the semisolid alimentation. Dysphagia is the most common symptom, but esophageal food impaction, respiratory distress or failure to thrive can be clinical manifestations of CES.

Interplay between STAT3, Cell Adhesion Molecules and Angiogenesis-Related Parameters in Gastric Carcinoma. Does STAT3 Really Have a Prognostic Value?

Gastric cancer (GC) is one of the deadliest malignancies, with the underlying pathophysiological mechanisms still not completely understood. In this study, we aimed to investigate the signal transducer and activator of transcription 3 (STAT3) moleculeconnection with the pathological features of GCs, and the expression of cell adhesive molecules (E-cadherin and β-catenin) and angiogenesis-related factors (vascular endothelial growth factor (VEGF), HIF1α, and CD31)). This study comprised 136 cases of GCs with data related to the patients' demographic characteristics (age, gender) and pathological features (tumor location, gross type, Laurens' type of GC, histological differentiation, invasion depth, lymphovascular invasion and the presence of metastases) which were correlated with STAT3 expression.
