Objective: The objective was to evaluate the etiology, natural history, and impact of surgical intervention on outcomes of left ventricular assist device (LVAD) patients presenting with intracranial hemorrhage (ICH).

Methods: The authors completed a retrospective review of LVAD patients who presented with ICH at 2 centers between 2013 and 2022. Patients were reviewed for demographic, clinical, and radiographic variables.

A magnetic macroporous α-FeO/MnO nanocomposite as an efficient adsorbent for simple and rapid removal of Pb(II) from wastewater and electronic waste leachate.

A magnetic nanocomposite adsorbent, comprised of macroporous iron oxide/manganese oxide (α-FeO/MnO), is prepared, characterized, and used for lead(II) removal from both industrial wastewater and leachate of electronic waste. The synergistic interaction between iron oxide and manganese oxide significantly enhances the adsorption performance. The surface characteristics and structural composition of the nanocomposite are examined using high-resolution transmission microscopy, X-ray spectroscopy, and Brunauer-Emmett-Teller methods.

Pretreatment factors associated with symptomatic stroke in Moyamoya disease patients: A multicenter study.

Objectives: Moyamoya disease (MMD) is a cerebrovascular disorder marked by the progressive steno-occlusion of the bilateral internal carotid arteries and the formation of abnormal collateral vessel networks at the base of the brain. Previous studies have attempted to identify risk factors predictive of postoperative complications to improve patient management. This study aims to identify pretreatment factors associated with post-bypass symptomatic strokes in MMD patients.

PGxDB: an interactive web-platform for pharmacogenomics research.

Pharmacogenomics, the study of how an individual's genetic makeup influences their response to medications, is a rapidly evolving field with significant implications for personalized medicine. As researchers and healthcare professionals face challenges in exploring the intricate relationships between genetic profiles and therapeutic outcomes, the demand for effective and user-friendly tools to access and analyze genetic data related to drug responses continues to grow. To address these challenges, we have developed PGxDB, an interactive, web-based platform specifically designed for comprehensive pharmacogenomics research.

A novel miniaturized potentiometric electrode based on carbon nanotubes and molecularly imprinted polymer for the determination of lidocaine.

A novel miniaturized, solid-contact potentiometric screen-printed electrode was developed for highly sensitive and selective determination of lidocaine anesthetic. The electrode integrated single-walled carbon nanotubes as a solid-contact material and a molecularly imprinted polymer as a recognition sensory material. The performance characteristics of the electrode were evaluated and optimized to display a Nernstian slope of 58.

Comparative Outcomes of Unilateral vs Bilateral Revascularization in Moyamoya Disease: A Multicenter Retrospective Study.

Background And Objectives: Moyamoya disease (MMD) is characterized by progressive steno-occlusion of the internal carotid arteries, leading to compensatory collateral vessel formation. The optimal surgical approach for MMD remains debated, with bilateral revascularization potentially offering more comprehensive protection but involving more extensive surgery compared to unilateral revascularization. This study aims to compare bilateral revascularization and unilateral revascularization short-term safety profile in the treatment of MMD.

Incidence, Management, and Outcomes of Pediatric Infectious Aneurysms.

Background And Objectives: Infectious intracranial aneurysms (IIAs) are rare cerebrovascular complications of infective endocarditis (IE) accounting approximatively for 0.5% to 6.5% of all aneurysms.

Novel paper-based potentiometric combined sensors using coumarin derivatives modified with vanadium pentoxide nanoparticles for the selective determination of trace levels of lead ions.

Novel miniaturized Pb(II) paper-based potentiometric sensors are described using coumarin derivatives I and II as electroactive ionophores and nano vanadium pentoxide as a solid contact material for the sensitive and selective monitoring of trace lead ions. Density functional theory (DFT) confirms optimum geometries, electronic properties, and charge transfer behaviors of 1:2 Pb(II): coumarin complexes. The sensors are prepared by using two strips of 20 × 5 mm filter paper with two circular orifices.

Impact of targeted drug administration and intermittent preventive treatment for forest goers using artesunate-pyronaridine to control malaria outbreaks in Cambodia.

Introduction: The national malaria programme of Cambodia targets the rapid elimination of all human malaria by 2025. As clinical cases decline to near-elimination levels, a key strategy is the rapid identification of malaria outbreaks triggering effective action to interrupt local transmission. We report a comprehensive, multipronged management approach in response to a  2022 Plasmodium falciparum outbreak in Kravanh district, western Cambodia.

Complement-dependent neuroinflammation in spinal cord injury: from pathology to therapeutic implications.

Spinal cord injury remains a major cause of disability in young adults, and beyond acute decompression and rehabilitation, there are no pharmacological treatments to limit the progression of injury and optimize recovery in this population. Following the thorough investigation of the complement system in triggering and propagating cerebral neuroinflammation, a similar role for complement in spinal neuroinflammation is a focus of ongoing research. In this work, we survey the current literature investigating the role of complement in spinal cord injury including the sources of complement proteins, triggers of complement activation, and role of effector functions in the pathology.

A novel potentiometric screen-printed electrode based on crown ethers/nano manganese oxide/Nafion composite for trace level determination of copper ion in biological fluids.

Copper levels in biological fluids are associated with Wilson's, Alzheimer's, Menke's, and Parkinson's diseases, making them good biochemical markers for these diseases. This study introduces a miniaturized screen-printed electrode (SPE) for the potentiometric determination of copper(II) in some biological fluids. Manganese(III) oxide nanoparticles (MnO-NPs), dispersed in Nafion, are drop-casted onto a graphite/PET substrate, serving as the ion-to-electron transducer material.

A case of myxopapillary ependymoma with predominant giant cell morphology: A rare entity with comprehensive genomic profiling and review of literature.

In the evolving landscape of ependymoma classification, which integrates histological, molecular, and anatomical context, we detail a rare case divergent from the usual histopathological spectrum. We present the case of a 37-year-old man with symptomatic spinal cord compression at the L3-L4 level. Neuroradiological evaluation revealed an intradural, encapsulated mass.

Long-term clinical outcomes of intravascular imaging-guided percutaneous coronary intervention versus angiography-guided percutaneous coronary intervention in complex coronary lesions: a systematic review and meta-analysis.

In this study, we aim to discuss the long-term clinical outcomes of intravascular ultrasound imaging-guided percutaneous intervention (IVUS-PCI) versus angiography-guided percutaneous coronary intervention (PCI) in complex coronary lesions over a mean period of 2 years. A systematic search and meta-analysis were conducted to assess the efficacy of using intravascular ultrasound or optical coherence tomography guidance in coronary artery stenting compared to angiography. A total of 11 randomized controlled trials with 6740 patients were included.

Tumor microenvironment and immune system preservation in early-stage breast cancer: routes for early recurrence after mastectomy and treatment for lobular and ductal forms of disease.

Background: Intra-ductal cancer (IDC) is the most common type of breast cancer, with intra-lobular cancer (ILC) coming in second. Surgery is the primary treatment for early stage breast cancer. There are now irrefutable data demonstrating that the immune context of breast tumors can influence growth and metastasis.

Repeat thrombectomy after large vessel re-occlusion: a propensity score matched analysis of technical and clinical outcomes.

Background: Endovascular thrombectomy (EVT) remains the standard of care for acute large vessel occlusion (LVO) stroke. However, the safety and efficacy of repeat thrombectomy (rEVT) in recurrent LVO remains unclear. This study uses a large real-world patient cohort to study technical and clinical outcomes after rEVT.
