Aβ42 biomarker linked to insula, striatum, thalamus and claustrum in dementia with Lewy bodies.

The differential mechanisms between proteinopathies and neurodegeneration in Alzheimer's disease (AD) and dementia with Lewy bodies (DLB) remain unclear. To address this issue, we conducted a voxel-based morphometry and cerebrospinal fluid biomarker (α-synuclein, Aβ42, t-Tau and p-Tau) level correlation study in patients with DLB, AD and mixed cases (AD + DLB). Cerebrospinal fluid samples obtained by lumbar puncture and whole-brain T1-weighted images were collected in the AlphaLewyMA cohort.

Personalized neuron-specific enolase level based on EEG pattern for prediction of poor outcome after cardiac arrest.

Background: After cardiac arrest (CA), the European recommendations suggest to use a neuron-specific enolase (NSE) level > 60 µg/L at 48-72 h to predict poor outcome. However, the prognostic performance of NSE can vary depending on electroencephalogram (EEG). The objective was to determine whether the NSE threshold which predicts poor outcome varies according to EEG patterns and the effect of electrographic seizures on NSE level.

Background:  The benefits and risks of extending anticoagulant treatment beyond the first 3 to 6 months in patients with venous thromboembolism (VTE) in clinical practice are not well understood.

Methods:  ETNA-VTE Europe is a prospective, noninterventional, post-authorization study in unselected patients with VTE treated with edoxaban in eight European countries for up to 18 months. Recurrent VTE, major bleeding, and all-cause death were the primary study outcomes.

Humanized Candida and NanoBiT Assays Expedite Discovery of Bdf1 Bromodomain Inhibitors With Antifungal Potential.

The fungal Bromodomain and Extra-Terminal (BET) protein Bdf1 is a potential antifungal target against invasive fungal infections. However, the need to selectively inhibit both Bdf1 bromodomains (BDs) over human orthologs and the lack of molecular tools to assess on-target antifungal efficacy hamper efforts to develop Bdf1 BD inhibitors as antifungal therapeutics. This study reports a phenyltriazine compound that inhibits both Bdf1 BDs from the human fungal pathogen Candida glabrata with selectivity over the orthologous BDs from the human BET protein Brd4.

Mortality risk stratification for Takotsubo syndrome: Evaluating CRP measurement alongside the InterTAK prognostic score.

Background And Objectives: Initially described as a benign acute cardiomyopathy, Takotsubo syndrome has been linked to elevated mortality rates. Emerging evidence suggests that unresolved myocardial inflammation may contribute to this adverse prognosis. This study aimed to evaluate the incremental prognostic utility of C-reactive protein (CRP) in conjunction with the InterTAK prognosis score for stratifying long-term mortality in Takotsubo syndrome.

Viability Assessment During Normothermic Machine Liver Perfusion: A Literature Review.

The discrepancy between donor organ availability and demand leads to a significant waiting-list dropout rate and mortality. Although quantitative tools such as the Donor Risk Index (DRI) help assess organ suitability, many potentially viable organs are still discarded due to the lack of universally accepted markers to predict post-transplant outcomes. Normothermic machine perfusion (NMP) offers a platform to assess viability before transplantation.

Clinical impact of an explainable machine learning with amino acid PET imaging: application to the diagnosis of aggressive glioma.

Purpose: Radiomics-based machine learning (ML) models of amino acid positron emission tomography (PET) images have shown efficiency in glioma prediction tasks. However, their clinical impact on physician interpretation remains limited. This study investigated whether an explainable radiomics model modifies nuclear physicians' assessment of glioma aggressiveness at diagnosis.

Risk Factors for Residual Unablated Tumour Following CT-Guided Percutaneous Renal Cryoablation: Lessons from the EuRECA Registry.

Objective: To assess tumour factors that reduce primary technical efficacy (PTE) from CT-guided renal cryoablation.

Methods: Patients were taken from the EuRECA registry between December 2014 and November 2020. To focus on tumour factors rather than individual technique, this study was limited to cases using CT and excluded procedures using cone beam, US, MRI, or laparoscopy.

Enhancing Biomechanical Simulations Based on a Posteriori Error Estimates: The Potential of Dual-Weighted Residual-Driven Adaptive Mesh Refinement.

The finite-element method (FEM) is a well-established procedure for computing approximate solutions to deterministic engineering problems described by partial differential equations. FEM produces discrete approximations of the solution with a discretisation error that can be quantified with a posteriori error estimates. The practical relevance of error estimates for biomechanics problems, especially for soft tissue where the response is governed by large strains, is rarely addressed.

Influence of Anticoagulants on Platelet Counts: A Study and Recommendations From the French Speaking Cellular Hematology Group (GFHC).

Introduction: For complete blood count, ethylenediaminetetraacetic acid (EDTA) is universally used and has been recognized as the most robust anticoagulant. However, it may lead to pseudothrombocytopenia (PTCT), due to the formation of platelet clumps, which is currently followed by resampling on sodium citrate. Other possible anticoagulants are citrate theophylline adenosine dipyridamole (CTAD) and MgSO.

Parosmia: Pathophysiology and Management.

Purpose Of Review: Parosmia is a qualitative olfactory disorder in which there is a mismatch between the memory of an odor and the actual experience triggered by an odor.

Biomarkers of sepsis-induced coagulopathy: diagnostic insights and potential therapeutic implications.

Diagnosing coagulopathy in septic patients remains challenging in intensive care. Disseminated intravascular coagulation (DIC) indeed presents with complex pathophysiology, complicating timely diagnosis. Epidemiological data indicate a significant prevalence of DIC in septic patients, with mortality rates up to 60%.

Total Pancreatectomy for Locally Advanced Pancreatic Adenocarcinoma with Coeliac Trunk Resection and Retrograde Gastric Revascularization Through Aorto-Hepato-Spleno Allograft.

Background: Locally advanced pancreatic adenocarcinomas (LA-PDAC) are more frequently operated now than in the past because of new regimen chemotherapy and improvement in surgical technique. Resection of the coeliac trunk (CT) during pancreatoduodenectomy (PD) or total pancreatectomy (TP) is not routinely done owing to the risk of liver and gastric ischaemia. In this video, a patient with LA-PDAC underwent TP with CT resection and retrograde gastric revascularization through the distal splenic artery.

Attentional Inhibition Ability Predicts Neural Representation During Challenging Auditory Streaming.

Focusing on a single source within a complex auditory scene is challenging. M/EEG-based auditory attention detection (AAD) allows to detect which stream an individual is attending to within a set of multiple concurrent streams. The high interindividual variability in the auditory attention detection performance often is attributed to physiological factors and signal-to-noise ratio of neural data.

Functional alignment in robotic-assisted total knee arthroplasty for valgus deformity achieves safe coronal alignment and excellent short-term outcomes.

Purpose: Functional alignment (FA) in total knee arthroplasty (TKA) prioritizes soft tissue balancing and anatomical restoration without systematic correction to neutral alignment. Most studies have focused on varus deformity, with little evidence available about FA in valgus deformity. The hypothesis of the present study was that FA in robotic-assisted TKA for valgus deformity would demonstrate correction of the coronal alignment and yield satisfactory short-term outcomes.

Plasma N-terminal tau fragment is an amyloid-dependent biomarker in Alzheimer's disease.

Introduction: Novel fluid biomarkers for tracking neurodegeneration specific to Alzheimer's disease (AD) are greatly needed.

Methods: Using two independent well-characterized cohorts (n = 881 in total), we investigated the group differences in plasma N-terminal tau (NT1-tau) fragments across different AD stages and their association with cross-sectional and longitudinal amyloid beta (Aβ) plaques, tau tangles, brain atrophy, and cognitive decline.

Results: Plasma NT1-tau significantly increased in symptomatic AD and displayed positive associations with Aβ PET (positron emission tomography) and tau PET.

Harnessing Multi-Center-2-Electron Bonds for Carbene Metal-Hydride Nanocluster Catalysis.

N-Heterocyclic carbene (NHC) ligands possess the ability to stabilize metal-based nanomaterials for a broad range of applications. With respect to metal-hydride nanomaterials, however, carbenes are rare, which is surprising if one considers the importance of metal-hydride bonds across the chemical sciences. In this study, we introduce a bottom-up approach leveraging preexisting metal-metal m-center-n-electron (mc-ne) bonds to access a highly stable cyclic(alkyl)amino carbene (CAAC) copper-hydride nanocluster, [(CAAC)6Cu14H12][OTf]2 with superior stability compared to Stryker's reagent, a popular commercial phosphine-based copper hydride catalyst.
