Intramural delivery of Sirolimus prevents vascular remodeling following balloon injury

2005

Abstract Objective. Several studies have demonstrated that Sirolimus-eluting stents reduce restenosis in patients with coronary artery disease. Here, we tested whether direct delivery of Sirolimus into the vessel wall during balloon angioplasty can modify vascular remodeling over several weeks. Methods and Results. During angioplasty of the rabbit iliac artery we administered an intramural infusion of Sirolimus or its vehicle directly through a balloon catheter into the vessel wall. After 3 weeks neointimal formation was decreased (0.71 ± 0.1 vs. 1.4 ± 0.12 intima/media ratio), and this process was attributed to the inhibitory properties of Sirolimus on ECM deposition and smooth muscle cell…

Restaging Patients With Hepatocellular Carcinoma Before Additional Treatment Decisions: A Multicenter Cohort Study

2018

Prognostic assessment of patients with hepatocellular carcinoma (HCC) at the time of diagnosis remains controversial and becomes even more complex at the time of restaging when new variables need to be considered. The aim of the current study was to evaluate the prognostic utility of restaging patients before proceeding with additional therapies for HCC. Two independent Italian prospective databases were used to identify 1,196 (training cohort) and 648 (validation cohort) consecutive patients with HCC treated over the same study period (2008-2015) who had complete restaging before decisions about additional therapies. The performance of the Italian Liver Cancer (ITA.LI.CA) prognostic score …

Problem-based learning for anesthesia resident operating room crisis management training.

2018

Background Senior anesthesia residents must acquire competency in crisis management for operating room (OR) emergencies. We conducted problem based learning (PBL) OR emergency scenarios for anesthesia residents, focused on emergencies in ‘Airway’, ‘Circulation’, ‘Central venous catheter’, and ‘Pain management complications’. Non-technical skills are an integral component of team-based OR emergency management. Methods Prior to integrated OR emergency clinical and non-technical skills PBL training, participating 35 anesthesia residents completed two 5-point scale surveys regarding frequency of emergency experiences in the operating room, and self-confidence for anesthesia-related crisis manag…

Neutral pH and low–glucose degradation product dialysis fluids induce major early alterations of the peritoneal membrane in children on peritoneal di…

2018

WOS: 000439138700024 PubMed ID: 29776755 The effect of peritoneal dialysates with low-glucose degradation products on peritoneal membrane morphology is largely unknown, with functional relevancy predominantly derived from experimental studies. To investigate this, we performed automated quantitative histomorphometry and molecular analyses on 256 standardized peritoneal and 172 omental specimens from 56 children with normal renal function, 90 children with end-stage kidney disease at time of catheter insertion, and 82 children undergoing peritoneal dialysis using dialysates with low-glucose degradation products. Follow-up biopsies were obtained from 24 children after a median peritoneal dial…

Predictors of clinical events occurring during hospital stay among elderly patients admitted to medical wards in Italy.

2016

Abstract Background Clinical events occurring during hospital stay are independent predictors of prolonged hospitalization, in-hospital mortality and readmission among elderly patients admitted to medical wards. Purpose To identify predictors of intercurrent clinical events (ICE) during hospital stay among the main demographic, functional and clinical characteristics assessed at hospital admission in a multicenter sample of elderly inpatients in Italy. Methods This observational prospective cohort study was conducted in 66 internal and geriatric medicine hospital wards in 2010. It enrolled 1267 inpatients aged 65 years or older living at home before hospitalization. Multivariable Poisson re…

Effect of a surveillance system for decreasing neonatal nosocomial infections.

2018

Nosocomial infection in very low birthweight (VLBW) infants is a common complication with high morbimortality. New strategies to reduce its occurrence have recently led to the development of neonatal surveillance programs.To determine whether the NeoKissEs surveillance system implementation in our neonatal unit has been associated with a decrease in nosocomial infection in VLBW infants, as well as a reduction in the use of antibiotics and central venous catheters (CVC).Retrospective and descriptive study of infants1500 g admitted between January 2011 and December 2017. Rates of use of antibiotics and CVC were calculated, as well as late-onset sepsis incidence. Data were compared before and …

Commentary to 'Early clean intermittent catheterization may not prevent dimercaptosuccinic acid renal scan abnormalities in children with spinal dysr…

2013

The authors aimed to address a clinically relevant issue: do we prevent new renal scarring by early administration of clean intermittent catheterization (CIC) in patients with spina bifida? In 2006, Peter Dik and co-workers presented their results of the concept of prophylactic initiation of CIC combined with antimuscarinic therapy in myelodysplastic newborns. Out of 144 children, five patients had pre-existing renal abnormalities, 69 had an overactive sphincter, 27 had reflux, and six had renal scarring. Five of the six patients with renal scarring were put on CIC and antimuscarinic therapy several months after birth. This study provided prima facie evidence that early initiation of CIC an…

Predilation technique with balloon angioplasty to facilitate percutaneous groin access of large size sheath through scar tissue

2017

Purpose Percutaneous remote access for endovascular aortic repair is an advantageous alternative to open access. Previous surgery in the femoral region and the presence of synthetic vascular grafts in the femoral/iliac arteries represent major limitations to percutaneous remote access. The aim of this study was to evaluate an original technique used for enabling percutaneous remote access for thoracic or abdominal endovascular aortic repair in patients with scar tissue and/or a vascular graft in the groin. Methods Twenty-five consecutive patients with a thoracic (11/25; 44%) or an aortic aneurysm (14/25; 66%) and with a synthetic vascular graft in the groin (16/25; 64%) or a redo groin acce…

A stochastic approach for automatic registration and fusion of left atrial electroanatomic maps with 3D CT anatomical images.

2007

The integration of electroanatomic maps with highly resolved computed tomography cardiac images plays an important role in the successful planning of the ablation procedure of arrhythmias. In this paper, we present and validate a fully-automated strategy for the registration and fusion of sparse, atrial endocardial electroanatomic maps (CARTO maps) with detailed left atrial (LA) anatomical reconstructions segmented from a pre-procedural MDCT scan. Registration is accomplished by a parameterized geometric transformation of the CARTO points and by a stochastic search of the best parameter set which minimizes the misalignment between transformed CARTO points and the LA surface. The subsequent …

Perineal complications following radical perineal prostatectomy.

2003

PURPOSE Radical perineal prostatectomy has recently attracted renewed interest and wider acceptance as an alternative route to the retropubic approach. While presumed lower morbidity is one reason for perineal prostatectomy we evaluated our patients for complications that are specific for the perineal approach. PATIENTS AND METHODS We have retrospectively analyzed 412 patients who underwent perineal prostatectomy from 10/1996 to 12/2000. Patients for the perineal approach were selected on the base of preoperative PSA (10 ng/ml) and biopsy Gleason score (< 7) without the need for simultaneous lymphadenectomy. A cystogram was performed routinely on day 7 p. o. and the catheter removed when pa…
