Glia-glia crosstalk via semaphorins: Emerging implications in neurodegeneration.

The central nervous system (CNS) is wired by a complex network of integrated glial and neuronal signals, which is critical for its development and homeostasis. In this context, glia-glia communication is a complex and dynamic process that is essential for ensuring optimal CNS function. Semaphorins, which include secreted and transmembrane molecules, and their receptors, mainly found in the plexin and neuropilin families, are expressed in a wide range of cell types, including glia.

Vaccination status among COVID-19 patients and duration of Polymerase Chain Reaction test positivity: evaluation of immunization schedule and type of vaccine.

Background: The introduction of the vaccine against SARS-CoV-2 has represented a cornerstone in the containment of the pandemic. Our aim was to assess the vaccination schedules in relation to the infection free interval and to the duration of positivity in case of infection.

Study Design: This study involves the SARS-CoV-2 infected people managed by the Local Health Authority ASL 1 Abruzzo.

Occupational risk perception of construction workers: a cross sectional study.

Introduction: Construction workers are often exposed to significant injury risk. The aim of our study is to assess their occupational hazards and injury risk perception.

Methods: We administered 256 questionnaires to construction workers.

Implementation of community health care services to counter the SARS-CoV2 pandemic.

Background: The COVID-19 pandemic has ravaged many countries worldwide since December 2019. The high infection rates, and the need for health care assistance for individuals with comorbidities, strained the national health care systems around the world. Outbreak peaks increased the burden on hospitals that where perceived as high-risk places by people, who often decided to cancel or defer hospital visits.
