<p>Early management of COPD: where are we now and where do we go from here? A Delphi consensus project</p>

2019

Purpose There is a lack of consensus on the most appropriate early diagnostic strategy, criteria for early access to treatment and follow-up approach for patients with COPD. Materials and methods A Delphi consensus project investigated the early management of COPD. We formulated two questionnaires for completion by pneumologists in Italy. Results A total of 207 specialists completed questionnaire 1 and 184 of them questionnaire 2, between November 2016 and October 2017. Early diagnosis of COPD was considered uncommon for 93.2% of the expert panel. Regardless of the definition of "early diagnosis" - a diagnosis made before the clinical manifestation of the disease for most responders (60.4%)…

A survey of seroprevalence of human papillomavirus types 16, 18 and 33 among children.

1999

The importance and natural history of HPV infections in childhood is incompletely understood. We performed a survey for presence of serum antibodies to HPV capsids among 1031 children aged 0 to 13 years, resident in Stockholm, Sweden. The HPV seroprevalence among these children was 3.0% for HPV16, 0.6% for HPV18 and 2.7% for HPV33. By comparison, among simultaneously analyzed positive control panels comprising women with CIN or healthy women with type-specific cervical HPV DNA, seroprevalence of HPV 16, 18 and 33 was 69%, 58% and 63% respectively. The results suggest that HPV infection in childhood is not common.

The Impact of Antiviral Therapy and the Influence of Metabolic Cofactors on the Outcome of Chronic HCV Infection

2010

Natural history of HCV related chronic hepatitis is influenced and modified by many factors: virus features, coinfections and host characteristics. In particular, a peculiar genetic background of the host by conditioning the occurrence of intracellular metabolic derangements (i.e., insulin resistance) might contribute to accelerate the rate of progression to cirrhosis and eventually the occurrence of hepatocellular carcinoma (HCC) and death. Likely, direct interplays between virus genotype and host genetic background might be hypothesized at this level. Morbidity and mortality in cirrhosis is primarily associated with complications of liver cirrhosis (ascites, hepatic encephalopathy, jaundi…

Las costas rocosas del Migjorn de Menorca: acantilados y calas

2017

[spa]La zona meridional de Menorca (Migjorn) se caracteriza por ser una plataforma carbonatada desarrollada en un ambiente arrecifal durante el Mioceno superior. Está surcada por una serie de cursos torrenciales fuertemente encajados que en su desembocadura al mar dan lugar a una forma de bahía denominada “cala” que está delimitada por paredes de elevada pendiente. La fracturación y la diaclasación penetrativa que afecta a la alternancia de materiales calcareníticos y calcisiltiticos miocenos, junto con la distribución de éstos, es el principal factor que condiciona el trazado de los cursos fluviales, así como el desarrollo de los procesos de tipo kárstico asociados a la circulaci…

The Revision of the Crustacea Collection of the Museum of Zoology “P. Doderlein” under the Framework of the National Biodiversity Future Center

2023

The collection of Crustacea preserved in the Museum of Zoology “P. Doderlein” in Palermo (Italy) has been revised in the framework of the activities of the National Biodiversity Future Center. The main part of the collection is composed of Decapoda, while a smaller part includes Stomatopoda, Isopoda, Amphipoda, and Cirripedia. Overall the collection includes common species, some of which are now protected.

Exotic Ants (Hymenoptera, Formicidae) Invading Mediterranean Europe: a Brief Summary over About 200 Years of Documented Introductions

2019

Exotic ants have emerged as a relevant topic worldwide because of their remarkable impacts on native ecosystems and human activities. A first regional overview is given on the dozens of exotic ant species recorded in Mediterranean Europe since the end of the 19th century. About 39 exotic ant species, belonging to 17 genera and originating from 5 different biogeographical realms, are currently believed to be established in this region. The genera Nylanderia and Tetramorium are those hosting the larger proportion of species, while the Afrotropical realm is the prevalent source of taxa. According to the available data, France, Greece, Italy and Spain all host a high number of exotic species, w…

Notes on Two Specimens of the Rare Swallowtail Eurytides iphitas Hübner, [1821] (Papilionidae) from the Friedrich Wilhelm Niepelt Collection in the M…

2021

Eurytides iphitas Hubner, [1821] is a rare swallowtail species endemic to southeast Brazil. Some authors believe that the species is extinct as the last live specimens were seen in 1937. During examination of the Friedrich Wilhelm Niepelt collection in the Museum of Natural History, University of Wroclaw, two specimens of this species were found. One of them has an enigmatic label “Peru Weberbauer S. G.”, which we can certainly attribute to the naturalist Otto Weberbauer, or his son August Weberbauer, the most famous pioneer of Peruvian botany.

Follow-up of patients after revascularisation for peripheral arterial diseases: a consensus document from the European Society of Cardiology Working …

2019

International audience; Peripheral arterial diseases comprise different clinical presentations, from cerebrovascular disease down to lower extremity artery disease, from subclinical to disabling symptoms and events. According to clinical presentation, the patient's general condition, anatomical location and extension of lesions, revascularisation may be needed in addition to best medical treatment. The 2017 European Society of Cardiology guidelines in collaboration with the European Society for Vascular Surgery have addressed the indications for revascularisation. While most cases are amenable to either endovascular or surgical revascularisation, maintaining long-term patency is often chall…

Expanding the phenotype of ASXL3 ‐related syndrome: A comprehensive description of 45 unpublished individuals with inherited and de novo pathogenic v…

2021

The study aimed at widening the clinical and genetic spectrum of ASXL3-related syndrome, a neurodevelopmental disorder, caused by truncating variants in the ASXL3 gene. In this international collaborative study, we have undertaken a detailed clinical and molecular analysis of 45 previously unpublished individuals with ASXL3-related syndrome, as well as a review of all previously published individuals. We have reviewed the rather limited functional characterization of pathogenic variants in ASXL3 and discuss current understanding of the consequences of the different ASXL3 variants. In this comprehensive analysis of ASXL3-related syndrome, we define its natural history and clinical evolution …
