Abstract
Aspergillosis is a disease caused by Aspergillus, and invasive pulmonary aspergillosis (IPA) is the most common invasive fungal infection leading to death in severely immuno-compromised patients. The literature reports Aspergillus co-infections in patients with COVID-19 (CAPA). Diagnosing CAPA clinically is complex since the symptoms are non-specific, and performing a bronchoscopy is difficult. Generally, the microbiological diagnosis of aspergillosis is based on cultural methods and on searching for the circulating antigens galactomannan and 1,3-β-D-glucan in the bronchoalveolar lavage fluid (bGM) or serum (sGM). In this study, to verify whether the COVID-19 period has stimulated clinicians to pay greater attention to IPA in patients with respiratory tract infections, we evaluated the number of requests for GM-Ag research and the number of positive tests found during the pre-COVID-19 and COVID-19 periods. Our data show a significant upward trend in GM-Ag requests and positivity from the pre-COVID to COVID period, which is attributable in particular to the increase in IPA risk factors as a complication of COVID-19. In the COVID period, parallel to the increase in requests, the number of positive tests for GM-Ag also increased, going from 2.5% in the first period of 2020 to 12.3% in the first period of 2021.

Abstract
Novel triorganotin(IV) complexes of two beta-lactamic antibiotics, 6-[D-(-)-beta-amino-p-hydroxyphenyl-acetamido]penicillin (=amoxicillin) and 6-[D-(-)-alpha-aminobenzyl]penicillin (=ampicillin), have been synthesized and investigated both in solid and solution states. The complexes corresponded to the general formula R(3)Sn(IV)antib*H(2)O (R=Me, n-Bu, Ph; antib=amox=amoxicillinate or amp=ampicillinate). Structural investigations about configuration in the solid state have been carried out by interpreting experimental IR and 119Sn Mössbauer data. In particular, IR results suggested polymeric structures both for R(3)Sn(IV)amox.H(2)O and R(3)Sn(IV)amp*H(2)O. Moreover, both antibiotics appear to behave as monoanionic bidentate ligands coordinating the tin(IV) atom through ester-type carboxylate, as well as through the beta-lactamic carbonyl. Evidence that in none of these compounds water molecules were involved in coordination, was provided by thermogravimetric investigations. On the basis of 119Sn Mössbauer spectroscopy it can be inferred that tin(IV) was pentacoordinate in all of the complexes in the solid state, showing an equatorial R(3)Sn(IV) trigonal bipyramidal (tbp) configuration. The nature of the complexes in solution state was investigated by using 1H and 13C nuclear magnetic resonance (NMR) spectroscopy, while an 119Sn spectrum was obtained for n-Bu(3)Sn(IV)amp*H(2)O. Although 1H- and 13C-NMR measurements suggested that in dimethyl sulfoxide (DMSO)-d(6) solution the polymeric structure collapsed, due to a solvolysis process of the beta-lactamic carbonyl bonding to the organometallic moiety, the complexes have been shown to maintain the same trigonal bipyramidal configuration at tin(IV) atom by the coordination of a DMSO molecule. Cytotoxic activity of these novel semisynthetic antibiotic derivatives has been tested towards spermatocyte chromosomes of the mussel Brachidontes pharaonis (Mollusca: Bivalvia) using two different chromosome-staining techniques such as Giemsa and CMA(3). The occurrence of typical colchicinized-like (c-like) mitoses on slides obtained from animals exposed to organotin compounds, directly confirmed the high mitotic spindle-inhibiting potency of these chemicals. In addition, by comparative analysis of spermatocyte chromosomes from untreated specimens (negative controls) and specimens treated with the triorganotin(IV) complexes, structural damages such as 'achromatic lesions' and 'chromosome breakages' have been identified.
