Background: The key advantage of active immunization is the induction of sustained, polyclonal antibody responses that are readily boosted by occasional immunizations. Recent clinical trial outcomes for monoclonal antibodies lecanemab and donanemab, establish the relevance of targeting pathological Abeta for clearing amyloid plaques in Alzheimer's disease. ACI-24.
View Article and Find Full Text PDFBackground: Clinical outcome assessments (COAs) that measure functional capacities are key tools to evaluate efficacy in Alzheimer's disease (AD) clinical trials. The Alzheimer's Disease Cooperative Study Activities of Daily Living (ADCS-ADL) scale is frequently used to assess changes in both basic and instrumental activities of daily living, but there is no clear consensus on what magnitude of change on this scale may be considered clinically meaningful. To address this question, we conducted anchor-based analyses (as recommended by the FDA) to explore meaningful within-patient/participant change thresholds on the ADCS-ADL.
View Article and Find Full Text PDFAmyloid β (Aβ) has been confirmed as a therapeutic target in AD by recent findings in Phase 3 trials with anti-Aβ antibodies. Modulators of γ-secretase (GSMs) are an emerging complementary approach to target amyloid. GSMs "modulate" the interaction between γ-secretase and amyloid precursor protein (APP), leading to a reduced production of long, amyloidogenic Aβ42 and Aβ40 and to concomitantly increased levels of the shorter, non amyloidogenic Aβ37 and Aβ38.

Cumulative evidence has indicated a potential reduction in cognitive decline in people with AD, while real-world evidence has shown decreased dementia risk in patients with type 2 diabetes. Non-clinical data reveal that GLP-1RAs impact neuroinflammation and other biological processes believed to be involved in AD pathophysiology, including effects on central and peripheral immune cells.

Distinct assessments are utilized for Down Syndrome-related Alzheimer's disease (DSAD). Although these assessments are less well established, they probe comparable domains of cognition and function.

Background: Due to further development of diagnostic methods of early-stage diagnosis of Alzheimer's disease (AD) and new disease-modifying treatment options that require early diagnosis, a new focus on predictive and preventive medicine arises. With progress in AD dementia risk estimation, guidelines for counseling, considering individual aspects of those affected, are becoming more important. As part of the trinational project PreTAD (The Predictive Turn in Alzheimer's Disease: Ethical, Clinical, Linguistic and Legal Aspects) anticipated effects of AD dementia risk estimation for first-degree relatives of people with AD dementia are evaluated.

Background: Driven by (bio-)medical and technical developments, advanced non-invasive methods for estimating the risk of Alzheimer's dementia (ADD) are increasingly emerging. In the future, such methods could eventually become available for individuals in asymptomatic and preclinical stages of Alzheimer's disease (e.g.
View Article and Find Full Text PDFBackground: With the recent approval of disease modifying therapies (DMT) for early Alzheimer's disease, there is a need for prescribing physicians to accurately communicate expectations of treatment effects to patients and their care partners. To better understand potential challenges and solutions to enhance this communication, physicians were surveyed, after which patients and care partners participated in focus groups.
Method: Step one consisted of an online survey of 100 US-based neurologists, geriatric medicine specialists and Alzheimer's disease specialists to ascertain physician perspectives on meaningful benefits associated with anti-amyloid monoclonal antibody treatment (DMT) over currently available symptomatic treatments.

The purpose of this study was to produce metabolite-specific T and concentration maps in a clinically compatible time frame. A multi-TE 2D MR spectroscopic imaging (MRSI) experiment (multi-echo single-shot MRSI [MESS-MRSI]) deployed truncated and partially sampled multi-echo trains from single scans and was combined with simultaneous multiparametric model fitting. It was tested in vivo for the brain in five healthy subjects.

Aim: Ventral mesh rectopexy (VMR) is an established surgical treatment for rectal prolapse and outlet obstruction. In contrast to continental Europe, in the UK and US the use of synthetic mesh has been abandoned in favour of biologic mesh, due to concerns regarding mesh related morbidity. The current study investigated if either material is superior, in terms of clinical recurrence and mesh related complications.

Background: The histologic classification of rhabdomyosarcoma (RMS) as alveolar (aRMS) or embryonal (eRMS) is of prognostic importance, with the aRMS being associated with a worse outcome. Specific gene fusions (PAX3/7::FOXO1) found in the majority of aRMS have been recognized as markers associated with poor prognosis and are included in current risk stratification instead of histologic subtypes in localized disease. In metastatic disease, the independent prognostic significance of fusion status has not been definitively established.

Buchwald-Hartwig (BH) aminations are crucial for synthesizing arylamine motifs in numerous bioactive molecules and fine chemicals. While homogeneous palladium complexes can be effective catalysts, their high costs and environmental impact motivate the search for alternative approaches. Heterogeneous palladium single-atom catalysts (SAC) offer promising recoverable alternatives in C-C cross-couplings.

Background And Objective: Thymic epithelial tumors, including thymomas and thymic carcinomas, represent the most common mediastinal tumors and account for up to 50% of all anterior mediastinal tumors. For early stages of these thymic tumors, complete resection of the entire thymus is the recommended treatment. The transition from open surgery to video-assisted thoracoscopic surgery (VATS) and recently to robotic-assisted thoracic surgery (RATS) has fundamentally altered the treatment of thymic tumors.

Mechanical and thermal cell damage can occur due to invasive procedures related to drilling, the insertion of dental implants, and periodontal treatments. Necrotic cells release the content of their cytoplasm and membrane fragments, thereby signaling the need for repair, which includes bone resorption by osteoclasts and inflammation. Here we screened lysates from human gingival fibroblasts, HSC2 and TR146 oral squamous carcinoma cell lines, as well as murine IDG-SW3 osteocytic and RAW264.

Even though α-arylation of ketones is attractive for direct C-H functionalization of organic substrates, the method largely relies on phosphine-ligated palladium complexes. Only recently, efforts have focused on developing nitrogen-based ligands as a more sustainable alternative to phosphines, with pyridine-functionalized pyridinium amidate (pyr-PYA) ,'-bidentate ligands displaying good selectivity and activity. Here, we report on a second generation set of catalyst precursors that feature a 5-membered N-heterocycle instead of a pyridine as chelating unit of the PYA ligand to provide less steric congestion for the rate-limiting transmetalation of the enolate.

Adsorption-based processes are showing substantial potential for carbon capture. Due to the vast space of potential solid adsorbents and their influence on the process performance, the choice of the material is not trivial but requires systematic approaches. In particular, the material choice should be based on the performance of the resulting process.

The discovery of unconventional superconductivity often triggers significant interest in associated electronic and structural symmetry breaking phenomena. For the infinite-layer nickelates, structural allotropes are investigated intensively. Here, using high-energy grazing-incidence x-ray diffraction, we demonstrate how in-situ temperature annealing of the infinite-layer nickelate PrNiO ( ≈ 0) induces a giant superlattice structure.
