Due to improvement in the management of patients with congenital heart disease (CHD), the likelihood of their survival to adulthood is increasing. A relevant population suffers end-stage right ventricular failure (RVF) in their 3rd-4th decade of life. Hence, heart transplantation is still gold standard of treatment of end-stage heart failure, mechanical circulatory assistance has become a valuable tool in the bridging to heart transplant or definitive therapy. Use of implantable short-term or long-term devices is reported by others. However, within this clinical context, presence of significant tricuspid regurgitation (TR) or CHD is used as exclusion criteria for insertion of a percutaneous right ventricular circulatory support.

We described a 36-year-old patient diagnosed with Ebstein's anomaly and severe TR who is admitted to hospital due to RVF refractory to standard medical treatment. After case presentation to the heart team, an Impella RP device insertion was scheduled, in spite of the presence of TR or CHD after evaluation of pulmonary valve competency and 3D reconstruction with virtual device implantation. During support, the patient improved clinically and haemodynamically. Due to device displacement to the right ventricle, it was bedside explanted after 30 days of support. After mechanical unloading during 30 days patients' right ventricle recovered partially, permitting patient to improve his functional class.

Although TR and CHD are exclusion criteria for the implantation of the Impella RP device, we report clinical experience in patient with Ebstein's anomaly and severe TR supported with percutaneous device as bridge to heart transplantation during 30 days.

Erectile dysfunction (ED) is a prevalent health problem that seriously impacts men's quality of life. The potential treatment of ED by percutaneous approach has emerged with valid angiographic results and a significant improvement in symptoms and quality of life. In addition, cell-based regenerative therapies aiming at enhancing neovascularization have been successfully performed with peripheral blood mononuclear cells (PBMNCs) in diabetic patients affected by critical limb ischaemia.

We report a case of a young insulin dependent (ID) diabetic patients who suffered of severe vasculogenic erectile dysfunction associated with a poor response for more than 1 year to oral phosphodiesterase-5 inhibitors (PDE5i) and intracavernous (IC) phosphodiesterase type 1 (PDE1) therapy. At selective angiography of the pelvic district, a severe atherosclerotic disease of the internal iliac and pudendal artery was evident with absence of distal vascularization of the cavernous bodies. The patient was treated by mechanical revascularization with drug-coated balloon and drug-eluting stent placement associated with IC injection of autologous PBMNCs. Immediate and 1-year clinical and angiographic follow-up are described.

Percutaneous revascularization with drug-coated balloon and drug-eluting stent associated with IC autologous PBMNCs cells injection is a safe and effective procedure to restore normal erectile function in diabetic patients affected by severe vasculogenic ED not responding to conventional oral drug therapies.

One of the key areas of our exploration is the Medical Information function within our organization. We receive a significant amount of medical information inquires in the form of unstructured text. An enterprise-level solution must deal with medical information interactions via multiple communication channels which are always nuanced with a variety of keywords and emotions that are unique to the pharmaceutical industry. www.selleckchem.com/ALK.html There is a strong need for an effective solution to leverage the contextual knowledge of the medical information business along with digital tenants of natural language processing (NLP) and machine learning to build an automated and scalable process that generates real-time insights on conversation categories. The traditional supervised learning methods rely on a huge set of manually labeled training data and this dataset is difficult to attain due to high labeling costs. Thus, the solution is incomplete without its ability to self-learn and improve. This necessitates techniques to automatically build relevant training data using a weakly supervised approach from textual inquiries across consumers, healthcare professionals, sales, and service providers. The solution has two fundamental layers of NLP and machine learning. The first layer leverages heuristics and knowledgebase to identify the potential categories and build an annotated training data. The second layer, based on machine learning and deep learning, utilizes the training data generated using the heuristic approach for identifying categories and sub-categories associated with verbatim. Here, we present a novel approach harnessing the power of weakly supervised learning combined with multi-class classification for improved categorization of medical information inquiries.Massive Open Online Courses (MOOCs) have become universal learning resources, and the COVID-19 pandemic is rendering these platforms even more necessary. In this paper, we seek to improve Learner Profiling (LP), i.e. estimating the demographic characteristics of learners in MOOC platforms. We have focused on examining models which show promise elsewhere, but were never examined in the LP area (deep learning models) based on effective textual representations. As LP characteristics, we predict here the employment status of learners. We compare sequential and parallel ensemble deep learning architectures based on Convolutional Neural Networks and Recurrent Neural Networks, obtaining an average high accuracy of 96.3% for our best method. Next, we predict the gender of learners based on syntactic knowledge from the text. We compare different tree-structured Long-Short-Term Memory models (as state-of-the-art candidates) and provide our novel version of a Bi-directional composition function for existing architectures. In addition, we evaluate 18 different combinations of word-level encoding and sentence-level encoding functions. Based on these results, we show that our Bi-directional model outperforms all other models and the highest accuracy result among our models is the one based on the combination of FeedForward Neural Network and the Stack-augmented Parser-Interpreter Neural Network (82.60% prediction accuracy). We argue that our prediction models recommended for both demographics characteristics examined in this study can achieve high accuracy. This is additionally also the first time a sound methodological approach toward improving accuracy for learner demographics classification on MOOCs was proposed.A micromagnetic study is carried out on the role of using topology to stabilize different magnetic textures, such as a vortex or an anti-vortex state, in a magnetic heterostructure consisting of a Permalloy disk coupled to a set of nanomagnetic bars. The topological boundary condition is set by the stray field contributions of the nanomagnet bars and thus by their magnetization configuration, and can be described by a discretized winding number that will be matched by the winding number of the topological state set in the disk. The lowest number of nanomagnets that defines a suitable boundary is four, and we identify a critical internanomagnet angle of 225° between two nanomagnets, at which the boundary fails because the winding number of the nanomagnet configuration no longer controls that of the disk magnetization. The boundary also fails when the disk-nanomagnets separation is > 50 nm and for disk diameters > 480 nm. Finally, we provide preliminary experimental evidence from magnetic force microscopy studies in which we demonstrate that an energetically unstable, anti-vortex-like structure can indeed be stabilized in a Permalloy disk, provided that the appropriate topological conditions are set.
The Wada test is used to evaluate language lateralization and memory performance after inactivation of an isolated cerebral hemisphere. Methohexital a short-acting barbiturate has a history of use to induce interictal discharges during intraoperative corticography. We report a new finding of activation of lateralized periodic discharges (LPDs) after Methohexital injection.

We retrospectively reviewed 174 consecutive adult patients who underwent Wada testing in preparation for epilepsy surgery (N = 129, 74%) or brain tumor resection (N = 45, 26%) at the University of Michigan to determine the frequency of induced periodic discharges by methohexital.

Four epilepsy patients (2.29%) had methohexital-induced LPDs within a median of 2 s (1-99 s) of the injection and lasting a median of 4 min (3-10 min) after a total of 7 injections. All LPDs occurred ipsilateral to the injection hemisphere in the known region of interictal epileptiform discharges. LPDs were not induced in brain tumor patients. In one patient, LPDs occurred during memory testing, and this patient's memory performance was below expectation based on pre-test neuropsychological testing.

Methohexital can induce LPDs in ipsilateral hemisphere and that can potentially affect memory performance.

This observation indicates that concurrent EEG monitoring during the Wada test is important and that induced discharges should be considered when interpreting Wada test results.

To report a case of central retinal artery (CRA) occlusion secondary to prepapillary loop in a 13-year-old girl.

A 13-year-old girl presented with a history of sudden visual loss in her left eye.

Fundus examination confirmed thrombosis in a prepapillary arterial loop causing CRA occlusion and extensive retinal ischemia. Macular region was watered by an anomalous macular branch, which explained her 20/20 vision central vision.

Congenital prepapillary vascular loops are rare and usually asymptomatic. We report a case of central artery occlusion confirmed by multimodal imaging.

To report a case of Sturge-Weber syndrome (SWS) complicated with uncontrolled glaucoma and serous retinal detachment (SRD) in the left eye that evolved with complete resolution after trabeculectomy.

We report the case of a 10-year-old boy with SWS complicated with uncontrolled glaucoma and SRD in the left eye. In primary evaluation, he presented with a left-sided nevus flammeus affecting upper eyelid and best corrected visual acuity of 20/50 on the affected eye. Fundus examination revealed glaucomatous optic nerve neuropathy and diffuse choroidal hemangioma with overlying SRD, which were confirmed with spectral domain optical coherence tomography. Right eye was unremarkable.

The patient underwent trabeculectomy with mitomycin-C on the affected eye. Two weeks later, he presented with normalization of the intraocular pressure and substantial resolution of subretinal fluid (SRF), which improved to complete resolution of the SRD at 2 months of follow-up. In addition, there was an improvement of visual acuity from 20/50 to 20/40.
