Quality of life in women undergoing urinary diversion for bladder cancer: results of a multicenter study among long-term disease-free survivors

2012

Purpose: Women undergoing radical cystectomy (RC) and urinary diversion for bladder cancer experience substantial limitations in health-related quality of life (HRQOL). However, the level of discomfort caused by different urinary diversion has been never evaluated in long term survivors. The aim of this multicenter study is to evaluate differences in HRQOL among recurrence-free women undergoing cutaneous ureterostomy (CUS), Bricker's ileal conduit (BK-IC) and Orthotopic neobladder VIP (ONB-VIP) in disease-free females treated with radical cystectomy (RC), with long-term follow up (mean 60.1 months; range 36-122 months). Materials and methods: All consecutively treated female patients from t…

Pediatric Urinary Diversion: Review and Own Experience

1992

New insights into the diseases of childhood, profound improvements and new developments in surgical techniques as well as the knowledge gained from long-term follow-up have altered the strategies and indications for urinary diversion in childhood. Continent urinary diversion is generally the method of choice. We are able to construct high capacity, low pressure reservoirs to protect the upper urinary tract and achieve continence. Nowadays, there is hardly any indication for permanent cutaneous urinary diversion. Temporary and intermediate cutaneous diversion are used only when serious conditions such as renal function deterioration occur. The possibility to convert any incontinent form of u…

Serological evidence for Borna disease virus infection in humans, wild rodents and other vertebrates in Finland

2005

Abstract Background Borna disease virus (BDV) can infect many vertebrate species, including humans. BDV infection may lead to meningoencephalomyelitis in animals. An association with human neuropsychiatric diseases has been reported, but the causal relationship between BDV and human disease remains unclear. Objectives and study design To find out whether BDV is present in Finland and to look for a potential reservoir, we examined a large panel of blood samples from different vertebrate species with immunofluorescence assay. Samples from horses, cats, dogs, sheep, cattle, large predators, grouse, wild rodents and humans were included. Most positive results were confirmed by other specific me…

Canine-Origin G3P[3] Rotavirus Strain in Child with Acute Gastroenteritis

2007

Infection by an animal-like strain of rotavirus (PA260/97) was diagnosed in a child with gastroenteritis in Palermo, Italy, in 1997. Sequence analysis of VP7, VP4, VP6, and NSP4 genes showed resemblance to a G3P[3] canine strain identified in Italy in 1996. Dogs are a potential source of human viral pathogens.

Pathogenic microorganisms carried by migratorybirds passing through the territory of the island ofUstica, Sicily (Italy)

2011

Several studies have shown that migratory birds play an important role in the ecology, circulation and dissemination of pathogenic organisms. In October 2006, a health status evaluation was performed on a large population of migratory birds passing through the territory of Ustica (Italy), an island located on the migration route of many species of birds to Africa, and various laboratory tests were conducted. In total, 218 faecal swabs and the internal organs of 21 subjects found dead in nets were collected for bacteriological and virological examination, including avian influenza and Newcastle disease. In addition, 19 pooled fresh faecal samples were collected for mycological examination. T…

Multiple Non-linear Reservoirs to Model Water Balance Components in Sandy Soils

2023

In the hydrologic literature, to model water flow in unsaturated soils, the Richards equation is usually applied, allowing the main components of the hydrologic cycle, as rainfall partitioning into surface runoff and infiltration, to be determined. The Richards equation is highly nonlinear, making very challenging to derive analytical solutions. Recently, for constant rainfall intensity, under the simplified hypothesis of gravity-driven infiltration, and by assuming a capacitance framework, a simplified solution of the Richards equation that considers the Brooks and Corey hydraulic conductivity function was suggested. By maintaining the assumption that the infiltration process is dominated …

The unnoticed northward expansion of Najas marina subsp. armata (Hydrocharitaceae) in the Mediterranean area: an effect of climate change?

2022

Recent reports of Najas marina L. (Hydrocharitaceae) from Sicily have been interpreted as a confirmation of its presence on the island, where it was earlier mentioned in the 1800s. However the recent finds do not represent “N. marina” (currently N. major All.) but N. marina subsp. armata Horn (= N. delilei Rouy), a different taxon, previously not recorded from Sicily. According to those reports and several new finds presented here, it appears to be invading reservoirs and lakes in southern Sicily and seems to be naturally expanding its range. Climate change is suggested as possible cause of this shift. The same trend appears to be taking place across the whole N Mediterranean area, from Por…

the role of lipids in the pathogenesis of neuroHIV

2020

A critical comorbidity of HIV infection is HIV-associated neurocognitive disorders (HAND). Although combined antiretroviral therapy (cART) is an effective treatment in blocking systemic viral replication, it is unsuccessful in reducing the incidence of HAND. HIV CNS damage, in the current cART era, can be associated to the presence of latently HIV-infected cells including microglia/macrophages and a small population of astrocytes. This Ph.D. thesis focuses on identifying, localizing, and quantifying viral reservoirs using an improved staining and microscopy technique. Although in low amount, our data confirmed that microglia/macrophages and a small population of astrocytes are still infecte…

Comparing biological classifications of freshwater phytoplankton: a case study from South China

2012

The use of ecological classification systems is becoming more and more widely used when studying phytoplankton. Grouping phytoplankton species into ecologically coherent groups allow to reduce redundancy and in this way, to handle a minor number of biological variables when investigating the ecological status of aquatic ecosystems. Three ecological classifications are mostly used when freshwater phytoplankton is studied: functional groups or coda, morpho-functional groups (MFGs) and morphology-based functional groups (MBFGs). In this study, these three ecological classifications were comparatively used along with two taxonomic classifications based on species and genera to analyse phytoplan…
