Sub-Optimal Compliance to Long-Term Inhalation Strategies and Poorer Health Care Outcomes Associated with Extended Tattoos in Adolescents with Mild-to-Moderate Bronchial Asthma.

Background: Patients' compliance to inhalation therapy is usually sub-optimal in young asthmatics. Adolescents poorly compliant to regular anti-asthma treatments and those with tattoos (and the associated attitude) can share some personality traits and maladaptive behaviors. This relationship has not been investigated.

Single-Breath Simultaneous Measurement of DL and DL as Predictor of the Emphysema Component in COPD - A Retrospective Observational Study.

Background: Chronic Obstructive Pulmonary Disease (COPD) is a respiratory condition characterized by heterogeneous abnormalities of the airways and lung parenchyma that cause different clinical presentations. The assessment of the prevailing pathogenetic components underlying COPD is not usually pursued in daily practice, also due to technological limitations and cost.

Aim: To assess non-invasively the lung emphysema component of COPD by the simultaneous measurement of DL and DL via a single-breath (sDL and sDL).

Performance evaluation of the 3D-ring cadmium-zinc-telluride (CZT) StarGuide system according to the NEMA NU 1-2018 standard.

Background: The application of semi-conductor detectors such as cadmium-zinc-telluride (CZT) in nuclear medicine improves extrinsic energy resolution and count sensitivity due to the direct conversion of gamma photons into electric signals. A 3D-ring pixelated CZT system named StarGuide was recently developed and implemented by GE HealthCare for SPECT acquisition. The system consists of 12 detector columns with seven modules of 16 × 16 CZT pixelated crystals, each with an integrated parallel-hole tungsten collimator.

mRNA vaccines protect from the lung microvasculature injury and the capillary blood volume loss occurring in SARS-CoV-2 paucisymptomatic infections.

Introduction: The reduction of lung capillary blood volume (Vc) had been identified as the microvascular injury mostly underlying the respiratory Long-COVID syndrome following post-COVID-19 pneumonia. The same kind of injury have been recently also found in several individuals after milder paucisymptomatic SARS-CoV-2 infections. Though current guidelines strongly recommend vac-cination, studies aimed to investigate the in vivo protection of anti-SARS-CoV-2 vaccines on lung microvascular targets still are missing to our best knowledge.
