Abstract

Phylogenetic analyses based on ITS-LSU rDNA sequences dataset indicate that Leucopaxillus, as currently defined, is a highly polyphyletic genus. The new genera Giacomia, Notholepista and Pseudoclitopilus are introduced to accommodate Leucopaxillus mirabilis, L. subzonalis and L. rhodoleucus, respectively. Leucopaxillus subg. Aspropaxillus also seems to represent an independent evolutionary line in the /tricholomatoid clade, for which we suggest resurrecting the genus Aspropaxillus. Furthermore, the morphologically allied genus Porpoloma is also polyphyletic.

The Prevalence of Malnutrition in Oncology (PreMiO) study identified malnutrition or its risk among cancer patients making their first medical oncology visit. Innovatively, oncologists, not nutritionists, evaluated the nutritional status of the patients in this study. Methods: PreMiO was a prospective, observational study conducted at 22 medical oncology centers across Italy. For inclusion, adult patients (>18 years) had a solid tumor diagnosis, were treatment-naive, and had a life expectancy >3 months. Malnutrition was identified by the Mini Nutritional Assessment (MNA), appetite status with a visual analog scale (VAS), and appetite loss with a modified version of Anorexia-Cachexia Subscale (AC/S-12) of the Functional Assessment of Anorexia-Cachexia Therapy (FAACT). Findings: Of patients enrolled ( N= 1,952), 51% had nutritional impairment; 9% were overtly malnourished, and 43% were at risk for malnutrition. Severity of malnutrition was positively correlated with the stage of cancer. Over 40% of patients were experiencing anorexia, as reported in the VAS and FAACT questionnaire. During the prior six months, 64% of patients lost weight (1–10 kg). Interpretation: Malnutrition, anorexia, and weight loss are common in cancer patients, even at their first visit to a medical oncology center.

16. Passive multifrequency forward-scatter radar measurements of airborne targets using broadcasting signals

Abstract

This paper demonstrates the feasibility and effectiveness of forward-scatter radar (FSR) target detection based on the signals of opportunity made available by standard radio and TV broadcast transmission stations. This passive FSR (P-FSR) operation is obtained by means of a simple and robust correlation process based on self-mixing. This is shown to be very effective in extracting the characteristic FSR modulation produced by airborne targets, from the signals received from frequency modulated, digital audio broadcasting, and digital video broadcasting transmitters of opportunity. Target detectability is discussed as a function of the carrier frequency, the target size, and its height at the baseline crossing. Experimental results are shown using a wide variety of sources of opportunity, target types, baselines, and receiver configurations. The target signatures obtained from the different illuminators are compared and ways of extracting the kinematic parameters of the aircraft are discussed. This validates the claimed effectiveness and robustness of the P-FSR with the presented processing scheme.

Abstract

A new species in the genus Tricholosporum, collected in the Dominican Republic, is taxonomically delimited based on morphological data. A detailed description, microscopic drawings and a colour plate of fresh material are presented. The new species is well circumscribed by the small cruciform to stauriform spores and mucronate, fusiform to ampullaceous and pigmented cystidia. A key to the accepted species of Tricholosporum is provided.

Abstract

A new Macrolepiota taxon from Italy, M. rhodosperma var. velicopia, is described and illustrated based on morphological and ITS rDNA data. It is characterized by a well-developed volva and abundant, evident velar remnants on the pileus, a stipe with a minutely squamulose covering, and very thick-walled elements in the pileipellis. A discussion on its taxonomic position within Macrolepiota and notes on closely related taxa are provided. DNA sequence analyses support the new taxon within the variability of M. fuliginosa sensu Vellinga, a non-volvate taxon that differs from Barla’s original sense of M. fuliginosa. As Barla did not indicate a holotype in his protologue of Lepiota procera var. fuliginosa and there are no extant original herbarium specimens, Barla’s Fig. 5/PL. 9 (from Les champignons des Alpes maritimes) is selected as a lectotype, and a recent collection from Liguria (Italy) is chosen as the epitype. A recent collection from Sardinia is chosen as epitype for L. permixta. Finally, M. fuliginosa and M. permixta are reduced in rank to forms of M. procera, based on their morphology.

Abstract

Acinetobacter baumannii is a ubiquitous microrganism often able to colonize and survive in different environments. Currently it is one of the most common pathogens responsible for nosocomial infections, including outbreaks, especially in long-term care facilities. The aim of this study was to show the results of an environmental investigation and genotyping analysis of multidrug-resistant Acinetobacter baumannii associated with an outbreak in an intensive care unit of a tertiary hospital located in Northern Sardinia, Italy. Positive cultures of MDR Acinetobacter baumannii were reported during the month of June 2012, after the collection of biological samples from ten patients. Acinetobacter baumannii was isolated during the following environmental investigation from the headboard of two beds. All the strains were genotyped by performing multiplex PCR to identify the presence of genes encoding carbapenemases. The results showed specific bands of blaOXA-51-like gene and of the blaOXA-23-like gene. PFGE highlighted minimal differences in genomic fingerprints, while the cluster analysis grouped the isolated microorganisms into two closely related clusters, characterized by Dice’s similarity coefficient equal to 95.1%. MLST showed that the strains belonged to ST31. The results of the study highlight the need, especially in high-risk areas, to adopt strict hygiene practices, particularly hand hygiene, and to ensure an appropriate turnover of personal protective equipment, which could be responsible for the spread of biological agents, such as MDR Acinetobacter baumannii.
