Between western European countries, the hepatitis C virus (HCV) endemic is highest in Italy. The main objective of this paper is to estimate the endemic diffusion of hepatitis C at the national level and by geographical area, with an extrapolation at the regional level and by uniform cohorts of subjects (by sex and year of birth). The secondary objective is a stratification by gravity of the estimated statistical figures to provide an overview of possible targets of the new anti-HCV treatments.PubMed and the Cochrane Library were searched for relevant Italian populations studies regarding HCV prevalence...

In pesticide residue analysis, relatively low-sensitivity traditional detectors, such as UV, diode array, electron-capture, flame photometric, and nitrogen-phosphorus detectors, have been used following classical sample preparation (liquid-liquid extraction and open glass column cleanup); however, the extraction method is laborious, time-consuming, and requires large volumes of toxic organic solvents. A quick, easy, cheap, effective, rugged, and safe method was introduced in 2003 and coupled with selective and sensitive mass detectors to overcome the aforementioned drawbacks...

Agrochemicals have been critical to the production of food and fiber, as well as the control of vectors of disease. The need for the discovery and development of new agrochemicals continues unabated due to the loss of existing products through the development of resistance, the desire for products with more favorable environmental and toxicological profiles, shifting pest spectrums, and changing agricultural needs and practices. As presented in the associated analysis of the agrochemical industry, the rising costs and complexities of agrochemical discovery has, in part, led to increasing consolidation, especially in the US and Europe...

Recent progress in the analysis of cell-free DNA fragments (cell-free circulating tumor DNA, ctDNA) now allows monitoring of tumor genomes by non-invasive means. However, previous studies with plasma DNA from patients with cancer demonstrated highly variable allele frequencies of ctDNA. Comprehensive genome-wide analysis of tumor genomes is greatly facilitated when plasma DNA has increased amounts of ctDNA. In order to develop a fast and cost-effective pre-screening method for the identification of plasma samples suitable for further extensive qualitative analysis, we adapted the recently described FAST-SeqS method...

PKHD1 gene mutations are found responsible for autosomal recessive polycystic kidney disease (ARPKD). However, it is inconvenient to detect the mutations by common polymerase chain reaction (PCR) because the open reading frame of PKHD1 is very long. Recently, long-range (LR) PCR is demonstrated to be a more sensitive mutation screening method for PKHD1 by directly sequencing. In this study, the entire PKHD1 coding region was amplified by 29 reactions to avoid the specific PCR amplification of individual exons, which generated the size of 1 to 7 kb products by LR PCR...

Venous thromboembolism (VTE) remains the number one preventable cause of hospital acquired mortality and morbidity. Each year, more than 12 million patients are at risk for VTE. The delivery of appropriate and timely VTE prophylaxis is still suboptimal in many healthcare institutions and can lead to increased readmissions, morbidity, as well as costs. To clarify this issue further, we performed a retrospective case control study at our institution to determine if poor adherence to the VTE prophylaxis guidelines could lead to an increase in VTE events...

The wildland-urban interface (WUI), the area where human development encroaches on undeveloped land, is expanding throughout the western United States resulting in increased wildfire risk to homes and communities. Although census based mapping efforts have provided insights into the pattern of development and expansion of the WUI at regional and national scales, these approaches do not provide sufficient detail for fine-scale fire and emergency management planning, which requires maps of individual building locations...

The morbidity and mortality associated with preeclampsia is staggering. The physiology of the Page kidney, a condition in which increased intrarenal pressure causes hypertension, appears to provide a unifying framework to explain the complex pathophysiology. Page kidney hypertension is renin-mediated acutely and ischemia-mediated chronically. Renal venous outflow obstruction also causes a Page kidney phenomenon, providing a hypothesis for the increased vulnerability of a subset of women who have what we are hypothesizing is a "renal compartment syndrome" due to inadequate ipsilateral collateral renal venous circulation consistent with well-known variation in normal venous anatomy...

A variable spectrum of urogenital malformations exists in girls with congenital adrenal hyperplasia (CAH). The vagina may enter the urethra at a variable level, and relations to the sphincter complex vary accordingly. Furthermore, an enlarged clitoris and variations in the bladder sphincter anatomy can be found. Endoscopy, genitography or magnetic resonance imaging (MRI) are commonly used for the assessment of these anomalies, and to provide information for counselling and treatment. When surgery is planned, introitoplasty cosmetical reduction of the clitoris and labioplasty are discussed with the families; introitoplasty is the most demanding aspect...

PURPOSE: To conduct a cost-effectiveness analysis study of sevelamer versus calcium-based binders (CBBs) in treating hyperphosphatemia among patients with end-stage renal disease (ESRD) in China. METHODS: A decision-analytic model of a lifetime horizon was used for base case analysis from the payers' perspective. The transition probabilities between different health states were derived from survival analysis. The overall survival of CBBs was derived from the Dialysis Clinical Outcomes Revisited study for up to 44 months and a Weibull regression model was used to extrapolate the overall survival to a lifetime horizon...

Psoriatic arthritis (PsA) is a chronic inflammatory rheumatic disease with a broad clinical spectrum. PsA can affect the axial skeleton, peripheral joints, entheses, synovial sheaths of tendons, skin, nails and extra-articular organs. Tumour necrosis factor alpha blockers (TNF blockers) were a breakthrough development in the treatment of PsA. Identifying predictors of response to biological therapies in patients with PsA is of utmost importance, especially in view of the costs and potential side effects of these agents...

The ubiquity and transferability of soil makes it a resource for the forensic investigator, as it can provide a link between agents and scenes. However, the information contained in soils, such as chemical compounds, physical particles or biological entities, is seldom used in forensic investigations; due mainly to the associated costs, lack of available expertise, and the lack of soil databases. The microbial DNA in soil is relatively easy to access and analyse, having thus the potential to provide a powerful means for discriminating soil samples or linking them to a common origin...
