Multi-Contrast Differentiation by Dual-Energy Spectral CT Angiography in a Patient with Pulmonary Barium Granulomas.

Barium inhalation usually relates to accidental aspiration during radiological procedures with an oral contrast agent. When present, barium lung deposits are visible as high-density opacities on chest X-ray or CT scan due to high atomic number, and they may be indistinguishable from calcifications. Dual-layer spectral CT has shown good material differentiation capabilities, due to its increased high-Z element range and smaller spectral separation between low- and high-energy spectral data.

The intriguing possibility of using probiotics in allergen-specific immunotherapy.

Allergen immunotherapy (AIT) can be considered the etiological therapy for allergic rhinitis and hymenoptera venom allergy. Its role is increasingly emerging in the context of IgE mediated food allergy, where the achievement of tolerance, or the permanent resolution of an allergy, represents the optimal goal of AIT. AIT treatment, indicated in adults and children with allergic rhinitis, has a preventative effect on the development of asthma and can also be used when asthma is associated to rhinitis; however, it is not the first choice for treatment of isolated asthma.

Mechanical bacterial lysate enhances antimicrobial barrier mechanisms in human airway epithelial cells.

Polyvalent mechanical bacterial lysate is effective in the prevention of respiratory tract infections, although its mechanism of action is not entirely elucidated. Because epithelial cells constitute the frontline defense against infections, we investigated the molecular mechanisms of innate response exerted by bronchial epithelial cells in the presence of polyvalent mechanical bacterial lysate. By using primary human bronchial epithelial cells, we observed that polyvalent mechanical bacterial lysate was able to increase the expression of cellular adhesion molecules such as ICAM-1 and E-cadherin, as well as the expression of amphiregulin, a growth factor able to support human bronchial epithelial cell proliferation.

The Italian registry for patients with Prader-Willi syndrome.

Background: Prader-Willi syndrome (PWS) is a rare and complex genetic disease, with numerous implications on metabolic, endocrine, neuropsychomotor systems, and with behavioural and intellectual disorders. Rare disease patient registries are important scientific tools (1) to collect clinical and epidemiologic data, (2) to assess the clinical management including the diagnostic delay, (3) to improve patients' care and (4) to foster research to identify new therapeutic solutions. The European Union has recommended the implementation and use of registries and databases.

IL-33 and the Cytokine Storm in COVID-19: From a Potential Immunological Relationship towards Precision Medicine.

Coronavirus SARS-CoV-2 has represented, and still represents, a real challenge from a clinical, diagnostic and therapeutic point of view. During acute infection, the increased levels of pro-inflammatory cytokines, which are involved in the pathology of disease and the development of SARS-CoV-2-induced acute respiratory disease syndrome, the life-threatening form of this infection, are correlated with patient survival and disease severity. IL-33, a key cytokine involved in both innate and adaptive immune responses in mucosal organs, can increase airway inflammation, mucus secretion and Th2 cytokine synthesis in the lungs, following respiratory infections.

Long-term home noninvasive ventilation (LTHNIV) in restrictive thoracic diseases: the Italian snapshot.

Long-term home noninvasive ventilation (LTHNIV) in restrictive thoracic diseases was explored via the recently published international REINVENT ERS survey. The Italian subset of respondents (ITA-r), the highest above all participating nations, was analyzed and compared to non-Italian respondents (NO-ITA-r). The ITA-r represented 20% of the total answers examined.

Incremental Value of Left Atrial Function Analysis in the Assessment of Left Ventricular Filling Pressures in Patients with ST-Elevation Myocardial Infarction.

Background: Left atrial (LA) reservoir strain provides interesting information about left ventricular (LV) filling pressure. However, the advantages of atrial reservoir strain in comparison with conventional parameters in patients with myocardial infarction are not clear yet.

Methods: Fifty patients with ST-elevation myocardial infarction (STEMI) prospectively underwent echocardiographic assessment of LV systolic and diastolic function by conventional parameters and two-dimensional speckle tracking longitudinal strain of left atrium.

Mechanical thrombectomy in minor stroke due to isolated M2 occlusion: a multicenter retrospective matched analysis.

Background: The purpose of this study was to evaluate the effectiveness of mechanical thrombectomy (MT) in patients with isolated M2 occlusion and minor symptoms and identify possible baseline predictors of clinical outcome.

Methods: The databases of 16 high-volume stroke centers were retrospectively screened for consecutive patients with isolated M2 occlusion and a baseline National Institutes of Health Stroke Scale (NIHSS) score ≤5 who received either early MT (eMT) or best medical management (BMM) with the possibility of rescue MT (rMT) on early neurological worsening. Because our patients were not randomized, we used propensity score matching (PSM) to estimate the treatment effect of eMT compared with the BMM/rMT.

Methods: This multicenter observational prospective cohort study enrolled 1678 consecutive patients receiving IVT for acute ischemic stroke at 6 Italian centers, undergoing fibrinogen concentration assessment at baseline, 2 hours and 6 hours after IVT.

Prevention of Recurrent Benign Paroxysmal Positional Vertigo: The Role of Combined Supplementation with Vitamin D and Antioxidants.

Benign paroxysmal positional vertigo (BPPV) usually has a favorable course, although it is possible to observe BPPV with a high recurrence rate. Previous studies suggested that vitamin D deficiency might affect BPPV recurrences, and oxidative stress might play a complementary role in BPPV pathogenesis. This multicentric trial aimed to evaluate the effectiveness of oral nutritional supplementation with a compound of alpha-lipoic acid, Carnosine, and Zinc (LICA® (Difass International, Coriano (RN), Italy)), vitamins of group B and vitamin D in preventing BPPV recurrences.

Cutting Edge: Hyperinflammatory Monocytes Expressing CD56 Abound in Severe COVID-19 Patients.

Proinflammatory monocytes play a preponderant role in the development of a cytokine storm causing fatal consequences in coronavirus disease 2019 (COVID-19) patients, highlighting the importance of analyzing in more detail monocyte distribution in these patients. In this study, we identified an atypical monocyte subpopulation expressing CD56 molecules that showed a low level of HLA-DR and high level of l-selectin. They released higher amounts of TNF-α and IL-6 and expressed genes associated with an excessive inflammatory process.

Myoinositol in Autoimmune Thyroiditis.

Myoinositol (Myo) is an isoform of inositol, a cyclic polyol with 6 hydroxyl groups. Myo is mainly derived from dietary intake while its endogenous production is generated from glucose by enzymatic reactions. Moreover, Myo is also synthesized by catabolism of phosphatidylinositol (PI), phosphoinositides (PIP), and inositol phosphates (IP).
