Post-operative computed tomography imaging evaluation of ascending aorta surgery

2021

Ascending thoracic aorta disease is often a life-threatening condition. Aortic aneurysm and aortic dissection are the most frequent ascending aorta diseases requiring surgical intervention. Surgical repair techniques of the ascending aorta are various; they include reconstruction of the ascending aorta by using a graft with or without a prosthetic valve, reconstruction with a composite artificial graft or using a biological graft, and reconstruction of the ascending aorta with a composite graft preserving the native valve and arch repair. The radiologist plays a key role in the identification of post-operative complications; differentiation from normal postoperative findings is fundamental.…

Relapse risk after autologous transplantation in patients with newly diagnosed myeloma is not related with infused tumor cell load and the outcome is…

2006

BACKGROUND AND OBJECTIVES: This European Group for Blood and Marrow Transplantation (EBMT) multicentre randomized phase III study was designed to assess the safety and efficacy of CD34+ selection in newly diagnosed myeloma patients undergoing autologous transplantation. DESIGN AND METHODS: One hundred and eleven patients responsive to initial chemotherapy were randomized to receive CD34+ selected (arm A) or unselected PBPC (arm B) after conditioning with high-dose melphalan and TBI. ASO-PCR was used to assess purging efficacy and reinfused tumor load. Tumor load could be assessed in 59 patients. RESULTS: CD34+ selection gave a median tumor cell depletion of 2.2 logs (0.77-5.96). No tumor ce…

Learning Design for Future Higher Education – Insights From the Time of COVID-19

2021

The COVID-19 pandemic brought many challenges in higher education. All teaching and learning activities were moved online. Universities had to provide adapted solutions to facilitate learning and maintain students’ engagement. Online education implies creating new learning environments with the help of digital technologies. Beyond the process of acquisition of knowledge, teachers needed to facilitate cooperative learning, build positive relations, and reduce negative emotions. We provide some expert insights based on empirical observations on teaching and assessment practices connected with psychology models applied in education. The aim of the paper is to formulate specific learning design…

La teoría de la autodeterminación : un marco motivacional para el aprendizaje basado en proyectos

2019

Resumen basado en el de la publicación Título, resumen, palabras clave en español e ingles Se describe cómo la mejora de la motivación escolar requiere de un marco teórico que permita establecer estrategias sencillas para guiar a los docentes en su práctica educativa. La teoría de la autodeterminación, con un corpus científico extenso, ha ayudado a entender mejor los elementos que inciden sobre la motivación en la práctica. Según este marco teórico, las formas autónomas de motivación requieren del desarrollo de tres necesidades psicológicas básicas: autonomía, competencia y relación con los demás. En el medio escolar, estas necesidades se ven favorecidas a través de contextos que fomentan l…

Comparison of Shod and Unshod Gait in Patients With Parkinson's Disease With Subthalamic and Nigral Stimulation

2022

Background: The Parkinsonian [i.e., Parkinson's disease (PD)] gait disorder represents a therapeutical challenge with residual symptoms despite the use of deep brain stimulation of the subthalamic nucleus (STN DBS) and medical and rehabilitative strategies. The aim of this study was to assess the effect of different DBS modes as combined stimulation of the STN and substantia nigra (STN+SN DBS) and environmental rehabilitative factors as footwear on gait kinematics.Methods: This single-center, randomized, double-blind, crossover clinical trial assessed shod and unshod gait in patients with PD with medication in different DBS conditions (i.e., STIM OFF, STN DBS, and STN+SN DBS) during differe…

In vitro evaluation of efficacy of different rotary instrument systems for gutta percha removal during root canal retreatment

2016

Background: Complete removal of old filling material during root canal retreatment is fundamental for predictable cleaning and shaping of canal anatomy. Most of the retreatment methods tested in earlier studies have shown inability to achieve complete removal of root canal filling. Therefore the aim of this investigation was to assess the efficacy of three different rotary nickel titanium retreatment systems and Hedstrom files in removing filling material from root canals. Material and Methods: Sixty extracted mandibular premolars were decoronated to leave 15 mm root. Specimen were hand instrumented and obturated using gutta percha and AH plus root canal sealer. After storage period of two …

Donor and host B cell-derived IL-10 contributes to suppression of graft-versus-host disease

2014

Graft-versus-host disease (GvHD) is a frequent life-threatening complication following allogeneic HSC transplantation (HSCT). IL-10 is a regulatory cytokine with important roles during GvHD, yet its relevant sources, and mode of action, remain incompletely defined in this disease. Using IL-10-deficient donor or host mice (BALB/c or C57BL/6, respectively) in a MHC-mismatched model for acute GvHD, we found a strongly aggravated course of the disease with increased mortality when either donor or host cells could not produce this cytokine. A lack of IL-10 resulted in increased allogeneic T-cell responses and enhanced activation of host DCs in spleen and MLNs. Remarkably, IL-10 was prominently p…

A perioperative uncontrollable bleeding in an elderly patient with acquired hemophilia A: a case report

2013

Key Clinical Message Acquired hemophilia A should be taken into account in the differential diagnosis of perioperative bleeding in patients without any apparent reason for activated partial thromboplastin time prolongation.

Utilización del manguito de isquemia en artroplastia total de rodilla. Práctica habitual en la Comunidad Valenciana y revisión bibliográfica

2019

The aim of this study is to know which is the routine clinical practice related to the use of ischemic tourniquet in total knee arthroplasty (TKA) in hospitals of Comunidad Valenciana and to make a Literature review. We performed a retrospective, descriptive, observational study based on questioner surveys of specialists in Orthopedic Surgery and Traumatology in 9 public Hospitals of Comunidad Valenciana 96, 9% of surgeons preferred the use of ischemic tourniquet in protheses implantation, versus 3,1% who did not. Among those who used Ischemic tourniquet, 57,8% preferred to inflate it before establishing a sterile field versus 39,1% who inflated the tourniquet once the sterile field was est…
