Progetto "La macchina estetica"

Il progetto lavora su un'ipotesi di trasformazione delle cave della Magliana, collocate nel quadrante ovest di Roma. Le cave, attualmente dismesse, costituiscono parte dei drosscapes, vuoti urbani semiabbandonati nel territorio della Coda della Cometa. La proposta progettuale da un lato riorganizza la catena di lavorazione attualmente presente ed al contempo integra spazi verdi e pubblici destinati ad attività ludiche e commerciali

CdTe compact gamma camera for coded aperture imaging in radioguided surgery

The aim of this work was to assess the performance of a prototype compact gamma camera (MediPROBE) based on a CdTe semiconductor hybrid pixel detector, for coded aperture imaging. This probe can be adopted for various tasks in nuclear medicine such as preoperative sentinel lymph node localization, breast imaging with 99mTc radiotracers and thyroid imaging, and in general in radioguided surgery tasks. The hybrid detector is an assembly of a 1-mm thick CdTe semiconductor detector bump-bonded to a photon-counting CMOS readout circuit of the Medipix2 series or energy-sensitive Timepix detector. MediPROBE was equipped with a set of two coded aperture masks with 0.07-mm or 0.08-mm diameter holes. We performed laboratory measurements of field of view, system spatial resolution, and signal-difference-to-noise ratio, by using gamma-emitting radioactive sources (109Cd, 125I, 241Am, 99mTc). The system spatial resolution in the lateral direction was 0.56 mm FWHM (coded aperture mask with holes of 0.08 mm and a 60 keV source) at a source-collimator distance of 50 mm and a field of view of 40 mm by side. Correspondingly, the longitudinal resolution in 3D source localization tasks was about 3 mm. MediPROBE showed a significant improvement in terms of spatial resolution when equipped with the high-resolution coded apertures, with respect to the performance previously reported with 1–2 mm pinhole apertures as well as with respect to adopting a 0.35 mm pinhole aperture

Granulomatous response to invasive pulmonary aspergillosis in an immunotherapy-naive host, a maladaptive response?

Pulmonary aspergillosis causes a wide spectrum of disease, ranging from asymptomatic airway colonization to severe invasive disease, contingent on the host's immune status and underlying pulmonary anatomy. The invasive form of aspergillosis is a rare occurrence in the immunocompetent population. Nevertheless, patients with a compromised innate immune response are at greatest risk. We present a case of a patient with known Crohn's disease who developed invasive pulmonary aspergillosis. His clinical picture was further complicated by an uncommon immune response characterized by the development of granulomas encasing the Aspergillus forms found on his lung biopsy, likely representing a maladaptive response, possibly related to the effects of his granulomatous disease in the lungs. He was successfully treated with antifungal therapy and video assisted thoracoscopic surgery with placement of thoracostomy tube drainage for a parapneumonic effusion. We will discuss the factors leading to his atypical presentation and clinical outcome

Whole Genome Sequence Dataset of Mycobacterium tuberculosis Strains from Patients of Campania Region

Abstract Tuberculosis (TB) is one of the deadliest infectious disorders in the world. To effectively TB manage, an essential step is to gain insight into the lineage of Mycobacterium tuberculosis (MTB) and the distribution of drug resistance. Although the Campania region is declared a cluster area for the infection, to contribute to the effort to understand TB evolution and transmission, still poorly known, we have generated a dataset of 159 genomes of MTB strains, from Campania region collected during 2018–2021, obtained from the analysis of whole genome sequence. The results show that the most frequent MTB lineage is the 4 according for 129 strains (81.11%). Regarding drug resistance, 139 strains (87.4%) were classified as multi susceptible, while the remaining 20 (12.58%) showed drug resistance. Among the drug-resistance strains, 8 were isoniazid-resistant MTB, 4 multidrug-resistant MTB, while only one was classified as pre-extensively drug-resistant MTB. This dataset expands the existing available knowledge on drug resistance and evolution of MTB, contributing to further TB-related genomics studies to improve the management of this disease
