Transcatheter aortic valve implantation (TAVI) serves a growing spectrum of patients with symptomatic severe aortic stenosis (AS). Approximately 80% of surgical aortic valve replacements is performed using a bioprosthesis1. Durability of surgical bioprostheses varies based on the patient's age at the moment of implantation, type and size etc2. TAVI has become the preferred treatment for degenerated aortic bioprostheses in elderly patients3. The median time since index surgical aortic valve replacement (SAVR) and for bioprosthetic valve degeneration is typically 8 - 10 years4-6. TAVI in this setting has proven to have equally favorable results as in native aortic valves7. Balloon expandable8 and self-expanding9 transcatheter heart valves (THV) can be used in a degenerated bioprosthesis and each have specific assets and limitations. TAVI in a failed bioprosthesis can cause coronary obstruction, THV migration, paravalvular leakage and prosthesis patient mismatch. The SAPIEN-3 / Ultra and EVOLUT R/Pro are the 2 most commonly used THV platforms in contemporary clinical practice including treatment of failing surgical aortic bioprostheses. Objective: To compare TAVI with EVOLUT R/Pro vs. SAPIEN-3 / Ultra in terms of device success. Study design: International multi-center randomized study with 1:1 randomization to TAVI with SAPIEN-3 / Ultra or Evolut R/Pro. Study population: 440 patients with a failing surgical aortic bioprosthesis (aortic stenosis with or without aortic regurgitation) and selected for transfemoral TAVI by heart-team consensus. Investigational intervention: Transfemoral TAVI with SAPIEN-3 / Ultra or Evolut R/PRO Main study parameters/endpoints: 1. Primary endpoint is device success at 30 days Defined by - Absence of procedural mortality AND - Correct positioning of a single prosthetic heart valve into the proper anatomical location AND - Intended performance of the prosthetic heart valve (no severe prosthesis- patient mismatch and mean aortic valve gradient < 20 mmHg or peak velocity < 3 m/s, AND no moderate or severe prosthetic valve regurgitation). Severe prosthesis patient mismatch is defined by effective orifice area (EOAi) ≤0.65 cm2/m2 2. Safety endpoint at 1 year defined by the composite of all-cause death, disabling stroke, rehospitalization for heart failure or valve related problems.
This study is observational and double blind. It evaluates the validity of presepsin (a serum biomarker of bacterial infections) as early biomarker of Ventilator Associated Pneumonia. It will be measured at day 0 (ICU admission) and every 48 hours in every patient with Sars-Cov 2 interstitial pneumonia requiring invasive mechanical ventilation (see inclusion ad exclusion criteria) until Day 30, ICU discharge or ICU death. There will be no change in clinical practice and in pneumonia diagnosis. We will examine how the elevation of presepsin level could be an early marker of ventilator associated pneumonia or a marker of bacterial pneumonia at ICU admission, before the microbiological results or clinical diagnosis.
The purpose of this protocol is to generate a large registry of patients with AL amyloidosis.
Anterior cruciate ligament (ACL) tear is mainly caused by sport injuries. 40% of injuries are attributed to noncontact mechanisms involving pivoting. Regaining quadriceps strength is a primary focus of patients pursuing a rehabilitation program after ACL reconstruction (ACLR). Unfortunately, despite rehabilitation programs aimed at reversing this muscle weakness, quadriceps strength deficits may persist for years. Moreover, this deficit leads to increased risk of sustaining another knee injury, and increased risk for developing posttraumatic osteoarthritis. At present, neither the optimal rehabilitative program nor the clinical and instrumental parameters to take into account at the time of return to activity have reached a consensus among clinicians. The investigators hypothesize that: - a persistent deficit in voluntary activation, that is an inability to achieve complete activation of a muscle, is present after ACLR. - this deficit in voluntary activation is associated with a phenomenon of "learned/acquired non-use" both in balance and during gait. This phenomenon will be demonstrated by investigating asymmetries in the recruitment of the injured lower limb in balance tests and during gait. - the "learned/acquired non-use" paradigm is associated to asymmetries in the hemispheric cortical activity. This phenomenon will be investigated through transcranial magnetic stimulation. The primary endpoint is the demonstration that the quadriceps muscle weakness after ACLR may represent a case of "learned non-use". This behaviour looks automatic and unconscious, so that the adjective "acquired" seems preferable to "learned". It consists of the under recruitment of the impaired side, once healed, as a form of unconscious protection, which is adopted when the contralateral side may carry out the function. The secondary outcome is the investigation of the correlation among the deficits in voluntary activation, in balance tests, during gait, and in the neurophysiologic trials, with the clinical conditions of the patients. It is expected that the injured lower limb show a deficit in the activation of the quadriceps muscle with respect to the contralateral one and with respect to normative data. The impaired limb will present lower recruitment in balance tests and a deficit in power production during gait. The contralesional hemisphere will demonstrate higher interhemispheric inhibition, lower short-interval intracortical inhibition (SICI) and higher short-interval intracortical facilitation (SICF) with respect to the ipsilesional hemisphere. The evidence for an asymmetry between the two lower limbs would support the hypothesis that the "acquired non-use" paradigm has a role in the deficits following ACL lesions and that it is unspecific across asymmetric impairments, and independent of the underlying disease. Results from the present study will allow: - the identification of clinical and instrumental criteria to guide the return-to-sport decision following ACLR. - the estimate of the sample size for future experimental protocols and new rehabilitative programs.
This study evaluates KRT-232, a novel oral small molecule inhibitor of MDM2, for the treatment of patients with Ph+ Chronic Myeloid Leukemia (CML) who have relapsed or are refractory or intolerant to a Tyrosine Kinase Inhibitor (TKI). This study is a global, open label Phase 1b/2 to determine the efficacy and safety of KRT-232 in patients with chronic phase CML (CML-CP) and accelerated phase (CML-AP) who have failed TKI treatments.
The management of COVID-19 patients in overwhelmed hospital facing the pandemic is a clinical challenge. The improvement of decision making may allow a better allocation of available resources and a better treatment of patients at higher risk. Chest CT has been widely adopted for COVID-19 pneumonia diagnosis. Several experiences documented the capability of Artificial Intelligence to improve and fasten COVID-19 pneumonia detection, mainly using chest X-ray. Aim of the present study was to develop and validate an Artificial Intelligence approach integrating clinical and imaging data (automatically extracted through the adoption of dedicated neural networks) for the creation of a cloud platform capable of performing automatic patients risk stratification. Such an approach could be used for triage of COVID-19 patients in the emergency department, with the aim to improve healthcare personnel decision-making and allocation of resources during health emergencies.
Colorectal surgery has made progressive advances in recent years related on one hand to the implementation of diagnostic methods that allow an early diagnosis of tumors and on the other hand to the development of therapeutic options based on laparoscopic surgery. In particular, multicenter clinical trials have shown that the laparoscopic approach to colorectal cancer had a comparable or even better outcomes in terms of perioperative complications and functional recovery of patients than traditional surgery. Complete Mesocolic Excision (CME) in right colonic resections is a surgical approach, of greater technical complexity, that appears to improve the oncological outcomes of these patients at the cost of an increased rate of complications. The highest rate of complications reported in the literature in patients undergoing CME was related to intraoperative bleeding due to the central vascular dissection that is performed. CT technological advances have made possible to perform CT angiography with multiplanar and three-dimensional reconstructions with the possibility of obtaining a detailed preoperative map of the vascular anatomy of these patients. CT scan was acquired immediately before contrast material injection and during arterial and venous phase. Arterial phase was obtained using the bolus tracking technique with an automated scan-triggering software. Image analysis was performed using multiplanar reformations (MPR), maximum intensity projection (MIP) and 3D volume rendering (VR) technique. The purpose of the CT was to identify three different parameters necessary for proper performance of CME and CVL and to compare preoperative observations with intraoperative evidence. All surgeries were performed by teams experienced in laparoscopic colorectal surgery. The investigators evaluated:- Fascia of Fredet; vascular structures; lymph nodes.

This is a single-center, paired-cohort, prospective study. Patients with a clinical suspicion of csPCa will receive mpMRI and Micro-US in two different visits. The results of the diagnostic procedures will determine how many and which type prostate biopsies patients will undergo. During the following visit, patients with both positive mpMRI and Micro-US, defined as the presence of one or more lesions with PI-RADS ≥ 3 and PRI-MUS ≥ 3 respectively, will receive a 12-core TRUSBx in addiction to MRI-TBx and Micro-US-TBx (Group 4). Patients with both negative mpMRI and Micro-US will receive a 12-core TRUSBx (Group 1). Patients with only positive mpMRI will receive MRI-TBx and 12-core TRUSBx (Group 2). Patients with only positive Micro-US-TBx will receive Micro-US-TBx and 12-core TRUSBx (Group 3). Our hypothesis is that the sensitivity for csPCa (defined as prostate cancer with Gleason score ≥ 3+4) of Micro-US will be superior or at least equal to that of mpMRI. Despite the introduction of the mpMRI and MRI-TBx has improved the diagnostic pathway of PCa, the proportion of men with negative mpMRI with a csPCa is still difficult to delineate due to the high variability of mpMRI negative predictive value (NPV) and specificity. In this context, a specific standardization of the use of Micro-US may play a crucial role to optimize PCa diagnostic pathway. Moreover, a direct comparison between Micro-US and mpMRI might be useful to determinate whether Micro-US could be more accurate than mpMRI for PCa diagnosis. Furthermore, in patients with suspicion of PCa the combined use between mpMRI and Micro-US might increase the detection of csPCa and reduce the number of unnecessary biopsies, improving mpMRI limitations in NPV and specificity. Demonstrating that Micro-US provides a similar sensitivity for csPCa as compared to mpMRI may lead to its definitive inclusion in daily clinical practice, potentially replacing mpMRI, streamlining the current diagnostic pathway of PCa.
