Inflammation | Year: 2013

The signaling system of phosphoinositides (PI) is involved in a variety of cell and tissue functions, including membrane trafficking, ion channel activity, cell cycle, apoptosis, differentiation, and cell and tissue polarity. Recently, PI and related molecules, such as the phosphoinositide-specific phospholipases C (PI-PLCs), main players in PI signaling were supposed to be involved in inflammation. Besides the control of calcium levels, PI-PLCs contribute to the regulation of phosphatydil-inositol bisphosphate metabolism, crucial in cytoskeletal organization. The expression of PI-PLCs is strictly tissue specific and evidences suggest that it varies under different conditions, such as tumor progression or cell activation. In a previous study, we obtained a complete panel of expression of PI-PLC isoforms in human umbilical vein endothelial cells (HUVEC), a widely used experimental model for endothelial cells. In the present study, we analyzed the mRNA concentration of PI-PLCs in lipopolysaccharide (LPS)-treated HUVEC by using the multiliquid bioanalyzer methodology after 3, 6, 24, 48, and 72 h from LPS administration. Marked differences in the expression of most PI-PLC codifying genes were evident. © 2013 Springer Science+Business Media New York.

Aim: To evaluate the incidence of bacteremia, and the isolated pathogens, in well-appearing children with fever without source (FWS) presenting to the pediatric emergency department (PED), after pneumococcal conjucate vaccine - 7 valent (PCV-7) widespread introduction in the Veneto region of north-eastern Italy, and to review the main literature contributions on the subject. Methods: Blood cultures performed at the PED of Padova from 1 June 2006 to 31 January 2009 in febrile children aged 1-36 months were retrospectively retrieved. Medical records of previously healthy well-appearing children with FWS were identified and reviewed. Results: The study finally included 392 patients. Bacteremia rate was 0.34% (95% CI 0-1) in the age group 3-36 months and 2% (95% CI 0-4.7) in infants 1-3 months. No Streptococcus pneumoniae was isolated. The literature review identified 10 relevant studies carried out in the USA and Spain showing an overall bacteremia rate <1% for feverish children aged 3-36 months, with values <0.5% in settings with high PCV-7 coverage. Conclusion: Overall bacteremia rate is currently <0.5% in well-appearing children aged 3-36 months with FWS attending the PED in areas with PCV-7 widespread vaccination and is sufficiently low to preclude laboratory testing in favour of close follow-up. Further research is needed to evaluate a more conservative approach in infants 2-3 months of age. © 2011 The Author(s)/Acta Pædiatrica © 2011 Foundation Acta Pædiatrica.

Techniques in Coloproctology | Year: 2016

Background: The aim of this study was to evaluate the impact of Surgical Unit volume on the 30-day reoperation rate in patients with CRC. Methods: Data were extracted from the regional Hospital Discharge Dataset and included patients who underwent elective resection for primary CRC in the Veneto Region (2005–2013). The primary outcome measure was any unplanned reoperation performed within 30 days from the index surgery. Independent variables were: age, gender, comorbidity, previous abdominal surgery, site and year of the resection, open/laparoscopic approach and yearly Surgical Unit volume for colorectal resections as a whole, and in detail for colonic, rectal and laparoscopic resections. Multilevel multivariate regression analysis was used to evaluate the impact of variables on the outcome measure. Results: During the study period, 21,797 elective primary colorectal resections were performed. The 30-day reoperation rate was 5.5 % and was not associated with Surgical Unit volume. In multivariate multilevel analysis, a statistically significant association was found between 30-day reoperation rate and rectal resection volume (intermediate-volume group OR 0.75; 95 % CI 0.56–0.99) and laparoscopic approach (high-volume group OR 0.69; 95 % CI 0.51–0.96). Conclusions: While Surgical Unit volume is not a predictor of 30-day reoperation after CRC resection, it is associated with an early return to the operating room for patients operated on for rectal cancer or with a laparoscopic approach. These findings suggest that quality improvement programmes or centralization of surgery may only be required for subgroups of CRC patients. © 2015, Springer-Verlag Italia Srl.

Anti-Cancer Drugs | Year: 2013

Treatment with angiogenesis inhibitors is becoming a cornerstone of modern anticancer therapy. Hypertension (HTN) is a common adverse event during antiangiogenic treatment and might represent a cancer biomarker in patients with recurrent glioblastoma treated with angiogenesis inhibitors. In a retrospective study, we analyzed 53 patients with recurrent glioblastoma treated with antiangiogenic drugs. Thirty patients were treated with sorafenib and 23 patients were treated with bevacizumab. All patients underwent brain gadolinium-enhanced MRI assessments according to the Radiologic Assessment in Neuro-Oncology criteria every 2 months or when clinically indicated. Blood pressure was measured before and during the treatment. We investigated whether treatment-related HTN may be associated with outcome in patients treated with antiangiogenic drugs. After 2 months of treatment, 24 patients (45%) achieved disease control: stable disease (17 patients) or a partial response (seven patients). The median overall survival from the start of antiangiogenic treatment was 7.3 months [95% confidence interval (CI) 6.02-8.5]; the median progression-free survival (PFS) was 2.7 months (95% CI 1.5-3.5); and the 6-month PFS was 32%. Twenty patients (38%) developed grades 2-3 HTN within 2 months of treatment. A significant association was found between HTN and disease control rate, and HTN and 6-month PFS; no significant association was found between HTN and the median PFS. According to univariate and multivariate analyses, HTN was related to a longer survival from antiangiogenic drug administration: 9.8 versus 4.8 months (P=0.001; hazard ratio=3.5, 95% CI 1.6-7.6). Our data indicate that HTN may be an effective biomarker in patients with recurrent glioblastoma treated with antiangiogenic drugs; in particular, it may be associated with a favorable effect on disease control, 6-month PFS, and the median overall survival. © 2012 Wolters Kluwer Health | Lippincott Williams & Wilkins.

Heart Rhythm | Year: 2011

Background: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited heart muscle disease carrying a risk of sudden death. Information about the clinical features during childhood and the age at disease onset is scanty. Objective: The aim of the study was to describe the ARVC phenotype as its initial clinical manifestation in a pediatric population (<18 years) with desmosomal gene mutations. Methods: Fifty-three ARVC desmosomal gene mutation carriers (mean age 12.3 ± 3.9 years) were investigated by electrocardiogram (ECG), signal-averaged ECG, 24-hour Holter, echocardiogram, and contrast-enhanced cardiac magnetic resonance (CMR). Results: None of the children ≤10 years old fulfilled the 1994 criteria, as opposed to six (33%) aged 1114 years and eight aged >14 years (42%). At the end of follow-up (9 ± 7 years), 21 (40%) fulfilled the 1994 diagnostic criteria (mean age 16 ± 4 years). By using the 2010 criteria in subjects aged ≤18 years, 53% were unaffected, versus 62% by using the traditional criteria. More than two-thirds of affected subjects had moderate-severe forms of the disease. Contrast-enhanced CMR was performed in 21 (40%); of 13 unaffected gene mutation carriers, six showed ARVC morphological and/or tissue abnormalities. Conclusion: In pediatric ARVC mutation carriers, a diagnosis was achieved in 40% of cases, confirming that the disease usually develops during adolescence and young adulthood. The 2010 modified criteria seem to be more sensitive than the 1994 ones in identifying familial pediatric cases. Contrast-enhanced CMR can provide diagnostic information on gene mutation carriers not fulfilling either traditional or modified criteria. Management of asymptomatic gene mutation carriers remains the main clinical challenge. © 2011 Heart Rhythm Society. All rights reserved.
