Tremor Following Guillain Barré Syndrome.

Background: Neuropathic tremor occurs with damage to the peripheral nervous system. Guillain-Barré syndrome (GBS) causes acute paralysis following nerve inflammation sometimes resulting in long-term disability. It is unclear how frequent and severe tremor is following GBS.

TAV-in-TAV in patients with prosthesis embolization: Impact of commissural alignment and global outcomes.

Background: Optimal strategies to manage embolization of transcatheter aortic valve implantation (TAVI) devices are unclear; valve-in-valve (ViV) is often used. We aimed to describe through one-single center experience its rate, causes, consequences, and management as well as the rate and relevance of commissural alignment (CA) in this context.

Methods: We identified across 1038 TAVI cases, those cases requiring ViV for the management of first device embolization.

Simultaneous Detection of Carbon Quantum Dots as Tracers for Interwell Connectivity Evaluation in a Pattern with Two Injection Wells.

This study aimed to develop and implement a nanotechnology-based alternative to traditional tracers used in the oil and gas industry for assessing interwell connectivity. A simple and rapid hydrothermal protocol for synthesizing carbon quantum dots (CQDs) using agroindustry waste was implemented. Three commercial CQDs were employed (CQDblue, CQDgreen, and CQDred); the fourth was synthesized from orange peel (CQDop).

Long-term prognostic value of quantitative-flow-ratio-concordant revascularization in stable coronary artery disease.

Objectives: Confirming the prognostic value of global QFR and evaluating the long-term prognosis of QFR-concordant therapy in stable coronary artery disease.

Background: Wire-based functional evaluation of coronary disease is linked to patient's prognosis. Quantitative Flow Ratio (QFR) is a newer index of computational physiology, linked to clinical outcomes and prognosis at 1 year follow-up.

Analysis of Wildfire Visualization Systems for Research and Training: Are They Up for the Challenge of the Current State of Wildfires?

Wildfires affect many regions across the world. The accelerated progression of global warming has amplified their frequency and scale, deepening their impact on human life, the economy, and the environment. The temperature rise has been driving wildfires to behave unpredictably compared to those previously observed, challenging researchers and fire management agencies to understand the factors behind this behavioral change.

Leukemia Cutis As the Initial Manifestation of Chronic Lymphocytic Leukemia Progression.

Chronic lymphocytic leukemia (CLL) is a malignant proliferation of monoclonal mature B-cells in peripheral blood. Leukemia cells can commonly spread from the blood to other sites such as the lymph nodes, liver, and spleen. However, contrary to T-cell lymphomas that can involve the skin, CLL metastasis to the skin is unusual and is rarely the first manifestation of systemic disease.

Anatomical classification of chronic total occlusions in coronary bifurcations.

Percutaneous coronary intervention (PCI) of chronic total occlusions (CTO) in coronary bifurcation lesions (CBL) is undergoing substantial technical progress and standardization, paralleling the evolution of dedicated devices, tools, and techniques. A standard consensus to classify CTO-CBL might be instrumental to homogenize data collection and description of procedures for scientific and educational purposes. The Medina-CTO classification replicates the classical three digits in Medina classification for bifurcations, representing the proximal main vessel, distal main vessel, and side branch, respectively.

Endothelial dysfunction in patients with angina and non-obstructed coronary arteries is associated with an increased risk of mayor cardiovascular events. Results of the Spanish ENDOCOR registry.

Background: Coronary endothelial dysfunction and vasospasm are potential causes of ischemia in patients without obstructive coronary stenoses (INOCA).

Objective: To evaluate the prevalence of endothelial dysfunction and the clinical profile of patients with INOCA in Spain, as well as to identify the predictors and the prognostic impact of endothelial dysfunction in this scenario.

Methods: A total of 438 consecutive patients with INOCA in whom the acetylcholine test was performed were prospectively enrolled.

Agreement between Murray law-based quantitative flow ratio (μQFR) and three-dimensional quantitative flow ratio (3D-QFR) in non-selected angiographic stenosis: A multicenter study.

Background: The agreement between single-projection Murray-based quantitative flow ratio (mQFR) and conventional three-dimensional quantitative flow ratio (3D-QFR) has not been reported hitherto.

Methods: Patients from a multinational database were randomly selected for the study of agreement, according to sample size calculation. Both conventional 3D-QFR and mQFR were analyzed for all available arteries at a central corelab by independent analysts, blinded to each other's results.

Comprehensive appraisal of cardiac motion artefact in optical coherence tomography.

Background: The relation between cardiac motion artefact (CMA) in optical coherence tomography (OCT) and the phases of cardiac cycle is unclear.

Methods: Optical coherence tomography pullbacks containing metallic stents were co-registered with angiography and retrospectively analyzed. The beginning of three phases, namely ejection, rapid-inflow and diastasis, was identified in angiography.

Neuronavigated Ultrasound in Neuro-Oncology: A True Real-Time Intraoperative Image.

Objective: Ultrasound is considered a real-time imaging method in neuro-oncology because of its highly rapid image acquisition time. However, to our knowledge, there are no studies that analyze the additional surgical time that it requires.

Methods: A prospective study of 100 patients who underwent intra-axial brain tumor resection with navigated intraoperative ultrasound.

: An Uncommon Human Pathogen Causing Infective Endocarditis in a Valve-in-Valve Transcatheter Aortic Valve Replacement.

is a fish pathogen and an uncommon cause of human infections. There is a growing body of evidence showing its potential for causing endocarditis especially in those with prior valve surgery. In this case report, we present what we believe is the first case of endocarditis by affecting a valve-in-valve transcatheter aortic valve replacement that was successfully treated.

Subintimal shift as mechanism for side-branch occlusion in percutaneous treatment of chronic total occlusions with bifurcation lesions.

Background: The aim of this study was to describe the mechanism of subintimal shift (SIS), standardise diagnostic criteria and sensitise the interventional community to this phenomenon. The treatment of chronic total occlusions (CTO) by means of percutaneous coronary intervention (PCI) is complicated by bifurcation lesions involved in the CTO segment or adjacent to it. Extraplaque expansion of intracoronary devices during CTO PCI may extend the dissection plane over the bifurcation with the consequential side or main branch compression by an intimo-medial flap.

Middle Cranial Fossa Approach: Anatomical Study on Skull Base Triangles as a Landmark for a Safe Anterior Petrosectomy.

 The Kawase approach provides access to the petroclival and posterior cavernous sinus regions, cerebellopontine angle, and upper basilar artery territory. Nevertheless, it remains one of the most challenging approach for neurosurgeons, due to the considerable related morbidity and mortality. The goal of this study was to evaluate the relationship between anatomical landmarks and their possible variations, and to measure the extension of the Kawase space, to define the reliability of these landmarks while performing an anterior petrosectomy.

Spontaneous coronary artery dissection in old patients: clinical features, angiographic findings, management and outcome.

Aims: Spontaneous coronary artery dissection (SCAD) is a relatively rare but well-known cause of acute coronary syndrome. Clinical features, angiographic findings, management and outcomes of SCAD in old patients (>65 years of age) remain unknown.

Methods And Results: The Spanish multicentre prospective SCAD registry (NCT03607981), included 318 consecutive patients with SCAD.

Spontaneous coronary artery dissection and Takotsubo syndrome: comparison of baseline clinical and angiographic characteristics and in-hospital outcomes.

Background: Spontaneous coronary artery dissection (SCAD) and Takotsubo syndrome (TTS) constitute two relatively common nonatherosclerotic causes of acute coronary syndrome particularly frequent in women.

Methods: This study sought to compare the baseline clinical and angiographic characteristics and in-hospital outcomes of patients from two large prospective registries on SCAD and TTS (the prospective nation-wide Spanish SCAD Registry and a prospective single-center TTS registry).

Results: A total of 318 SCAD and 106 TTS consecutive patients were included.

Artery of Percheron and Endoscopic Endonasal Surgery: Case Report and Review of the Literature.

Artery of Percheron (AOP) is a rare anatomical variant in which a single perforating artery arising from the P1 segment of the posterior cerebral artery supplies paramedian thalami and rostral midbrain. The occlusion of AOP produces bilateral thalamic ischemia and may be a rare complication in relation to an extended endoscopic endonasal approach. We report the case of a patient who developed AOP damage during endoscopic endonasal surgery (EES); to our knowledge, this complication has been previously reported only in one case, in relation to a second surgery.

Identification of the type of stent with three-dimensional optical coherence tomography: the SPQR study.

Background: The ability of optical coherence tomography (OCT) to identify specific types of stent has never been systematically studied.

Aims: The aim of this study was to test the accuracy of OCT imaging to identify patterns of stent platform and subsequently identify the type of stent implanted.

Methods: Consecutive patients from six international centres were retrospectively screened, searching for OCT studies with metallic stents or scaffolds.
