Analysis and evaluation of periodic physiological organ motion in radiotherapy treatments.

2003

Background and purpose: A system for the detection, measurement and analysis of the periodic physiological organ motion during radiotherapy treatment is proposed and clinically tested in this paper. Material and methods: The procedure is based on the acquisition of fluoroscopic sequences, followed by an automatic detection of the movement using cross-correlations with matched filters. Results: The system generates a probability density function (PDF) of finding a mobile organ in a position at a certain time. The maximum path of the mobile structures can be determined to define the planning target volume (PTV) without ambiguities. Conclusions: Physiological movements can be accurately includ…

Multicenter and all-comers validation of a score to select patients for manual thrombectomy, the DDTA score.

2021

Background Routine manual thrombectomy (MT) is not recommended in primary percutaneous coronary intervention (P-PCI) but it is performed in many procedures. The objective of our study was validating the DDTA score, designed for selecting patients who benefit most from MT. Methods Observational and multicenter study of all consecutive patients undergoing P-PCI in five institutions. Results were compared with the design cohort and the performance of the DDTA was analyzed in all patients. Primary end-point of the analyses was TIMI 3 after MT; secondary endpoints were final TIMI 3, no-reflow incidence, in-hospital mortality and in-hospital major cardiovascular events (MACE). In-hospital prognos…

No difference in 30-day outcome and quality of life in transradial versus transfemoral access – results from the German Austrian ABSORB registry (GAB…

2021

Abstract Background Radial (RA) instead of femoral access (FA) for coronary interventions has become a European Society of Cardiology Class-IA guideline recommendation. But when the decision on the access site is left to the discretion of the operator, differences in adverse event rates mitigate. Methods We compared the 30-day outcome for RA and FA in all patients recruited for the observational German Austrian ABSORB Registry (GABI-R) in regard to all-cause mortality, stroke, myocardial infarction (MI), TIMI major bleedings (TMB) and quality of life (QoL). All patients were treated with a bioresorbable vascular scaffold. Access site was left to the discretion of the operator. Results In to…

Robotic Versus Laparoscopic Staging for Early Ovarian Cancer: A Case-Matched Control Study.

2017

Abstract Study Objective To evaluate the feasibility, surgical outcome, and oncologic results observed after robotic staging compared with conventional laparoscopic staging for patients with early-stage ovarian cancer patients. Design A retrospective cohort study (Canadian Task Force classification II-2). Setting Catholic University of the Sacred Heart, Rome, Italy. Patients Ninety-six patients underwent minimally invasive staging for presumed stage I ovarian cancer; 32 underwent the robotic approach (cases), and 64 underwent the laparoscopic approach (controls). Measurements and Main Results There was no statistically significant difference between the 2 approaches with regard to final Fed…

Real-world Adherence and Persistence with Bisphosphonate Therapy in Postmenopausal Women: A Systematic Review

2018

Abstract Purpose Bisphosphonate therapy is a well-established and effective treatment for postmenopausal osteoporosis and the prevention of osteoporotic fracture. However, poor adherence to and poor persistence with bisphosphonate therapy may reduce its benefits. Previous studies have documented the poor rates of adherence and persistence among postmenopausal women with osteoporosis. The objective of this systematic literature review was to evaluate adherence, persistence, and the impact of adherence and persistence on fracture risk in postmenopausal women with diagnosed osteoporosis. Methods Articles eligible for review included observational studies of the real-world use of bisphosphonate…

Altemeier's procedure for complete rectal prolapse; outcome and function in 43 consecutive female patients.

2019

Background The aim of this retrospective study was to evaluate morbidity, mortality, postoperative function and recurrences in patients treated by Altemeier’s rectosigmoidectomy for complete rectal prolapse in a referral center for pelvic floor functional disorders. Methods Peri-operative data on 43 consecutive female patients were reviewed. At follow-up any change in pelvic floor function and recurrences were determined. Thirty four patients were assessed at a median interval of 49 (2–135) months, six being deceased for reason not related to the prolapse and three lost to follow-up. Results Post-operative complications at 30 days occurred in 18 patients (38%). Major complication occurred i…

The European multicenter cohort study on cyanoacrylate embolization of refluxing great saphenous veins

2014

ObjectiveCyanoacrylate (CA) embolization of refluxing great saphenous veins (GSVs) has been previously described. The outcomes from a multicenter study are still lacking.MethodsA prospective multicenter study was conducted in seven centers in four European countries to abolish GSV reflux by endovenous CA embolization. Neither tumescent anesthesia nor postinterventional compression stockings were used. Varicose tributaries remained untreated until at least 3 months after the index treatment. Clinical examination, quality of life assessment, and duplex ultrasound evaluation were performed at 2 days and after 1, 3, 6, and 12 months.ResultsIn 70 patients, of whom 68 (97.1%) were available for 1…

The QRS narrowing index for easy and early identification of responder to cardiac resynchronization therapy.

2013

The rationale for cardiac resynchronization therapy (CRT) in patients with heart failure (HF) is based on the possibility of inducing substantial left ventricular reverse remodeling. It is well known that some of these patients don't benefit from this therapy (the so-called non-responders) [1,2]. No better predictors of a positive answer to CRT than pre-CRT QRS duration (QRSd) were found [3,4]. The aim of our study was to identify a parameter for an easy and early identification of responders to CRT. In this regard, according to Rickard et al., we identified and observed QRS index (QI), as an expression of electrical remodeling after CRT, and its relation with anatomic reverse remodeling, e…

Pancreatoduodenectomy with artery-first approach.

2019

"Artery-first approach" encompasses different aspects for the surgical treatment of pancreatic cancer. It is a surgical technique or set of techniques which share in common the dissection of the main arterial vasculature involved in pancreatic cancer, before any irreversible surgical step is performed. On the other hand it represents the need for a meticulous dissection of the arterial planes and clearing of the retropancreatic tissue between the superior mesenteric artery, the common hepatic artery and portal vein in an attempt to achieve R0 resections. The recent expansion of this approach is based mainly on three factors: venous involvement should not be considered a contraindication for…
