[The CCM Project "Phenotypic and molecular screening methodologies for the detection of coloniza-tions due to carbapenem-resistant Enterobacterales (CRE)"].

Carbapenem-resistant Enterobacterales (CREs) are globally considered to be a major threat to public health. National and international guidelines emphasize the importance of routine active surveillance policies to prevent their transmission. Consequently, screening for the evaluation of the status of colonization by CREs in hospitalized patients in Italy is considered essential to contain and control the spread of these microorganisms and their evolution towards infection.

How different attributes are weighted in professionals' decision-making in Pediatric Dentistry-a protocol for guiding discrete choice experiment focused on shortening the evidence-based practice implementation for dental care.

Background: Important evidence has been constantly produced and needs to be converted into practice. Professional consumption of such evidence may be a barrier to its implementation. Then, effective implementation of evidence-based interventions in clinical practice leans on the understanding of how professionals value attributes when choosing between options for dental care, permitting to guide this implementation process by maximizing strengthens and minimizing barriers related to that.

Multicomponent Antibiofilm Lipid Nanoparticles as Novel Platform to Ameliorate Resveratrol Properties: Preliminary Outcomes on Fibroblast Proliferation and Migration.

The well-being of skin and mucous membranes is fundamental for the homeostasis of the body and thus it is imperative to treat any lesion quickly and correctly. In this view, polyphenols might assist and enhance a successful wound healing process by reducing the inflammatory cascade and the production of free radicals. However, they suffer from disadvantageous physico-chemical properties, leading to restricted clinical use.

Multicentre Surveillance of Species from Blood Cultures during the SARS-CoV-2 Pandemic in Southern Europe (CANCoVEU Project).

: Surveillance of species isolates from blood cultures (BCs) in Europe is considered fragmented, unable to allow the definition of targets of antifungal stewardship recommendations especially during the SARS-CoV-2 pandemic. : We performed a multicentric retrospective study including all consecutive BC isolates from six Southern European tertiary hospitals (1st January 2020 to 31st December 2021). Etiology, antifungal susceptibility patterns, and clinical setting were analyzed and compared.

Four-Year Environmental Surveillance Program of spp. in One of Palermo's Largest Hospitals.

is a ubiquitous bacterium that lives in freshwater environments and colonizes human-made water systems. is the most virulent species, and risk factors for Legionnaires' disease include increasing age, smoking, chronic diseases, and immunodeficiency. For this reason, it is very important to assess and monitor hospital water systems in order to prevent legionellosis.

Transfusion-Transmitted Malaria of in Palermo, Sicily.

Transfusion-transmitted malaria (TTM) is a rare occurrence with serious consequences for the recipient. In non-endemic areas, the incidence of transmission of malaria by transfusion is very low. We report a clinical case of transfusion-transmitted malaria due to , which happened in a patient with acute hemorrhagic gastropathy.

Draft Genome Sequence and Biofilm Production of a Carbapenemase-Producing (KpR405) Sequence Type 405 Strain Isolated in Italy.

Rapid identification and characterization of multidrug-resistant strains is essential to diagnose severe infections in patients. In clinical routine practice, is frequently identified and characterized for outbreak investigation. Pulsed-field gel electrophoresis or multilocus sequence typing could be used, but, unfortunately, these methods are time-consuming, laborious, expensive, and do not provide any information about the presence of resistance and virulence genes.

Improvement of a rapid direct blood culture microbial identification protocol using MALDI-TOF MS and performance comparison with SepsiTyper kit.

Fast diagnosis of pathogens is critical to guarantee the most adequate therapy for infections; bacterial culture methods, which constitute the actual gold standard, are precise and sensitive but rather slow. Today, new methods have been made available to enable faster diagnosis, with the Matrix-Assisted Laser Desorption Ionization-Time Of Flight Mass Spectrometry (MALDI-TOF MS) technique being the most promising. Even if simpler and faster than traditional bacterial culture methods, analysis of positive blood cultures via MALDI-TOF MS requires a preliminary extraction process of samples.

Abrasion and blunt tissue trauma study of a novel flexible robotic system in the porcine model.

Objectives: The objective of this study was to determine if a flexible robotic system caused increased tissue reaction when accessing the oropharynx and hypopharynx compared to intubation controls in only 2 scenarios: high speed tissue impact and multiple unit insertions and retractions. The data obtained were submitted as part of the entirety of information submitted for FDA approval.

Methods: This study consisted of 5 groups of Yorkshire pigs (2 animals per group).

Composites between hydroxyapatite and poly(epsilon-caprolactone) synthesized in open system at room temperature.

The hydroxyls present on the surface of hydroxyapatite (HA) granules, annealed at 700 composite function, 900 composite function and 1,100 composite function C, are able to initiate the polymerization of epsilon-caprolactone (CL), not only at 185 composite function C under vacuum, but also at room temperature in open system. A polymer layer ionically linked to the substrate is formed on HA surface, enhancing the compatibility between the organic phase and the inorganic one in composite biomaterials. We studied the characteristics of the polymer, produced by the reaction carried out at room temperature in open system, as well as the percentages of the poly(epsilon-caprolactone) (PCL) ionically bonded to the HA structure and of the "free" one.

In vitro cytotoxicity testing of chitosan-containing polyelectrolyte complexes.

Two chitosan-containing polyelectrolyte complexes, chitosan-poly(acrylic acid) and chitosan-poly(styrenesulphonate), were synthesized by polymerizing acrylic acid and sodium styrenesulphonate in the presence of chitosan and chitosan hydrochloride, respectively. The complexes were studied by optical microscopy and tested for cytotoxicity by the Neutral Red uptake, Kenacid Blue R-Binding and 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyl tetrazolium bromide assays. The optical microscopy confirmed the differences in crystallinity and structure already found for the two polycomplexes by other characterization techniques.

Release of 5-fluorouracil by biodegradable poly(ester-ether-ester)s. Part I: release by fused thin sheets.

The 5-fluorouracil release by biodegradable epsilon-caprolactone and L-lactide copoly(ester-ether-ester)s was tested. The drug-copolymer mixture was formed by fusion in thin sheets, which were dipped in Dulbecco's PBS for time intervals ranging from one hour to two months. Each experiment shows a fast initial release, which subsequently slows down and stops at a limiting value, depending on the copolymer composition.

New composites of hydroxyapatite and bioresorbable macromolecular material.

Composite materials were prepared by mixing in different proportions of hydroxyapatite (HA) and poly(epsilon-caprolactone-oxyethylene-epsilon-caprolactone) block copolymer (PCL-POE-PCL) to produce a new resorbable material for biomedical applications. This material has proved to be very interesting for production of periodontal membranes. Mechanical properties are linearly proportional to the amount of HA introduced.

Periodontal membranes from composites of hydroxyapatite and bioresorbable block copolymers.

Biomembranes are frequently proposed as devices for "guided bone regeneration." Such membranes consist generally of a thin sheet of polymeric material, mostly textured from polymeric yarns or clots, which all have a diffuse very fine winding porosity. The cross-section size of the holes of such porosity is nanometric (diameter < 0.

Fibers by bioresorbable poly(ester-ether-ester)s as potential suture threads: a preliminary investigation.

Fibers made by a bioresorbable poly(epsilon-caprolactone)-block-poly(oxyethylene)-block-poly(epsilon-caprolactone) copolymer, having a number average molecular mass of about 200,000 Da and an average molar composition of 66% oxycaproyl units and 34% oxyethylene units, were melt-spun, with the aim at using them as suture threads. Their properties were investigated by the stress-strain test and by differential scanning calorimetry (DSC). The results obtained show that the properties of this material depend very strongly on the alignment of its macromolecules.

Solving the problems of duality: the third and self-consciousness.

Locating the concept of the third in the debate about countertransference that began in the 1950s, the authors maintain that it originated to solve problems stemming from the recognition that the analytic encounter takes place between two individual subjects. This recognition can lead to discomfort for the analyst, once objective criteria to interpret reality have been lost due to adhesion to a dialectical constructionist perspective; it also implies a deeper involvement arising from the abandonment of neutrality. The concept of the third is often invoked to help avoid these risks.

Cell cultures in the biocompatibility study of synthetic materials.

In vitro cytotoxicity (Neutral Red uptake, Kenacid Blue and MTT) and cytocompatibility (cell adhesion and proliferation) tests were applied to the biocompatibility study of a series of poly(ester-ether-ester) block copolymers of potential interest as biomaterials. Our results indicate that the copolymer extracts after 72 hours incubation with a 3T3 mouse fibroblast cell line do not induce significant toxic effects. Furthermore, human umbilical vein endothelial cells seeded on thin copolymer films show a normal pattern of growth.
