Respiratory protection is a factor which worries nursing professionals who take care of patients susceptible of transmitting microorganisms through the air more as every day passes. This type of protection covers the use of surgical or hygienic masks against the transmission of infection by airborne drops to the use of highly effective masks or respirators against the transmission of airborne diseases such as tuberculosis or SARS, a recently discovered disease. The adequate choice of this protective device and its correct use are fundamental in order to have an effective protection for exposed personnel. The authors summarize the main protective respiratory devices used by health workers, their characteristics and degree of effectiveness, as well as the circumstances under which each device is indicated for use.

Carbon black is a key component of air-borne particulate matter, linked to adverse health outcomes, such as increased susceptibility to respiratory infections and chronic pulmonary disease exacerbations. Fine and ultrafine particles can penetrate the lungs, enter the bloodstream, and induce pathogenetic events. Macrophages play a crucial role in responding to inhaled particles, including carbon black, by initiating an innate immune response and upregulating pro-inflammatory cytokines and anti-oxidative enzymes.

Lung macrophage cells play a critical role in various lung diseases, and their state can change depending on the progression of the disease by inducing either an inflammatory or anti-inflammatory state. In this review, the potential therapeutic effects of treatment with antioxidant nanoparticles in air-borne diseases focusing on porcine reproductive and respiratory virus (PRRSV), considering reactive oxygen species (ROS) as one of the factors that regulate M1 and M2 macrophages in the inflammatory and anti-inflammatory states, respectively, was described. In addition, the author examines the status of protein structure research on CD163 (one of the markers of anti-inflammatory M2 macrophages) in human and veterinary lung diseases.

Article Synopsis
- Tuberculosis (TB) is an airborne infectious disease that continues to cause significant health issues globally, despite advancements in diagnosis and treatment.
- In high-income countries, TB is less common but still presents socio-economic challenges, highlighting the need for effective management and awareness.
- Pulmonologists play a crucial role in TB care due to its complexities, global travel factors, varied symptoms, and the potential for drug resistance.

Introduction: COVID-19 pandemic had impacted the reporting of notifiable communicable diseases. Since the beginning of the pandemic and the introduction of relate public health measures, notifications for most notifiable diseases have declined compared to previous years. In this study, we aim to quantify the changes in the incidences of notifiable infectious diseases during and after the pandemic in Siracusa Local Health Authority, Italy.
