Combining plasma p-tau217 and cross-cultural cognitive tests to identify Alzheimer's Disease in an ethnically diverse mixed memory clinic cohort

Objective: To determine whether combining routine cross-cultural cognitive assessments with plasma phosphorylated tau217 (p-tau217) increases diagnostic accuracy in identifying Alzheimer's disease (AD) in a consecutive mixed memory clinic cohort of ethnically diverse patients. Methods: We included 201 memory clinic patients originating from 42 different countries. Patients were examined with the M

Personalised regional modelling predicts tau progression in the human brain

Aggregation of the hyperphosphorylated tau protein is a central driver of Alzheimer’s disease, and its accumulation exhibits a rich spatiotemporal pattern that unfolds during the course of the disease, sequentially progressing through the brain across axonal connections. It is unclear how this spatiotemporal process is orchestrated, namely, to what extent the spread of pathologic tau is governed b

Genome-wide association study of REM sleep behavior disorder in Parkinson’s disease

REM sleep behavior disorder (RBD), is a prodromal synucleinopathy affecting a subset of Parkinson’s disease (PD) patients and associated with neuropsychiatric symptoms. This study compared the genetic profiles of 13,020 PD patients with probable RBD (PD + RBD) and 5403 without (PD-RBD) using genome-wide association study (GWAS). RBD was assessed by questionnaires or self-reporting. Potential genet

Association between older adults’ socioeconomic status and their healthcare experiences, preferences, and attitudes towards deprescribing : a cross-sectional study in 14 countries

Background: Socioeconomic status (SES) can influence health outcomes. Both SES and older age are associated with polypharmacy, health literacy, and quality of care. Understanding how SES influences healthcare experiences of older adults with polypharmacy can serve to inform future interventions aiming at optimising patient care. Therefore, we investigated the association between older patients’ SE

Addressing the risk of ocular complications of GLP-1RAs; a multi-disciplinary expert consensus

Aims: There is current apprehension among some clinicians and conflicting evidence regarding ocular complications in relation to Glucagon-like peptide-1 receptor agonists (GLP-1RAs). We aimed to generate multi-disciplinary, expert-led consensus recommendations relating to ocular complications to facilitate optimum prescribing of GLP-1RAs. Materials and Methods: A modified Delphi was conducted foll

Plasticity in Daphnia eye size is determined by intra-generational environmental conditions

Variation in the structure and size of the eye in relation to light environments is well-documented across animal taxa. However, the long-term effects of ultraviolet radiation (UVR) on eye size across generations remain understudied, despite natural fluctuations in UVR being common in aquatic habitats. Here, we used Daphnia magna to test whether an evolutionary history of UVR threat modifies plast

Genomic insights into the genetic basis of the seed size and weight revealed by the Chinese peanut key landraces

Key message: A candidate gene exhibiting pleiotropic effect on twelve different seed size and weight traits was identified through a combination of evidence from population genetic selection, GWAS, earlier QTL studies, transcriptome analysis, and transgenic analyses. Abstract: Peanut is an important oilseed crop. Seed weight and size significantly impact yield, leading to the identification of num

Cretaceous sea turtle soft tissues clarify ancestry of scale loss in chelonioids

Scale loss is a quintessential hydrodynamic adaptation in marine reptiles, and paralleled the pelagic specializations of Mesozoic ichthyosaurs, plesiosaurs, and metriorhynchid crocodylians, as well as the modern Leatherback Sea turtle (Dermochelyidae). By contrast, modern hard-shelled sea turtles (Cheloniidae) retain both scutes and scaly flippers, despite evolving from among partially scale-less

Teaching sustainability - workshops – bridging real-world challenges from different systemic levels

To prepare students for addressing wicked problems such as climate change and inequality, higher education must foster systemic and interdisciplinary thinking. We developed a flexible, interactive workshop grounded in sustainability goals and transitions theory to promote abductive reasoning across disciplines. Using cases on food waste, fashion, and e-waste, the workshop was tested in four divers

Analysis of Droughts and Floods Evolution and Teleconnection Factors in the Yangtze River Basin Based on GRACE/GFO

In recent years, under the influence of climate change and human activities, droughts and floods have occurred frequently in the Yangtze River Basin (YRB), seriously threatening socioeconomic development and ecological security. The topography and climate of the YRB are complex, so it is crucial to develop appropriate drought and flood policies based on the drought and flood characteristics of dif

Symptoms and objective signs of peripheral sensory neuropathy in POTS and correlations to gastrointestinal symptoms

Aim Postural orthostatic tachycardia syndrome (POTS) is a disorder with cardiovascular autonomic dysfunction where multiple and variable symptoms are common, including those from the peripheral and enteric nervous systems. We aimed to investigate subjective and objective signs of small and large fiber neuropathy in a Swedish POTS cohort compared with healthy controls. Secondly, we wanted to examin

Lessons of history : Learning from catastrophe and crisis in twentieth-century Europe

Historical lessons are useful or even necessary for our guidance and orientation in time. These lessons, however, have often been overlooked in historical reflections on watershed moments, such as genocides, treaties, and global movements. Focusing on how cataclysmic events, primarily within Central and Eastern Europe, have been transmitted across borders and generations, this volume interrogates

The economic power of elites, human capital, and industrial change in late Imperial Russia

This paper studies the economic impacts of land ownership concentration among the aristocratic elite in the Russian Empire. I document that areas with a higher concentration of noble land ownership were associated with lower levels of primary education during 1880–1911. Exploring the mechanisms, I show that by controlling local governments the landed elites decreased public spending on education,

Factors associated with poor prognosis in elderly biopsy-only glioblastoma patients

Purpose: Glioblastoma (GBM) in elderly patients has a poor prognosis. About one-third of patients have impaired perioperative performance status (PS) and often excluded from clinical trials. Brain biopsy is the standard diagnostic approach when resection is not feasible. Previous studies on preoperative prognostic factors have mostly focused on resected patients. This study aimed to identify preop

How energy and chemistry converge for a fossil-free future

The chemical industry must undergo a dual transformation: electrifying energy use and defossilizing carbon feedstocks. This paper, developed by ENGIEs Scientific Council, examines how energy and chemistry can converge to enable this shift. We assess the roles of biomass, recycled plastics, and CO2 as sustainable carbon sources and explore the enabling potential of electrification, low-carbon hydro

Some issues of accessibility in online social services: direct access versus signposting

Easy and low-threshold access is considered to be a major advantage of online services. In Sweden, social services in several municipalities strive to increase their accessibility by responding to anonymous users online. This paper raises the question about the nature of accessibility that the online social services entail. Two online platforms were studied: synchronous online chats and asynchrono

Performing the Sacred/Secular Nation: The Centenary of Izmir as a Dynamic of Memory-Contest in Turkish Nationalism

How is Turkish official memory negotiated locally in Izmir, a city celebrated as a symbol of national becoming, yet (im)famous for its scepticism of central power? How is the past of the city narrated, conceived as an epitome of progress, yet built on a systematic forgetting of trauma and violence? And how does the secularist legacy of Izmir, accentuated in contrast with the Islamisation of memory

Triumph and Trauma: Commemorating the Conquest of Izmir in State and (Trans)Local Narrative

On October 29 2023, Turkey celebrates the centenary of the Republic. We may anticipate this to be an equally spectacular and politicized event: a purported celebration of national unity, which in essence will reproduce and re-affirm distinct political wedges. Carefully choreographed national celebration has a long history in Turkey. And historiography has been its narrative bedrock, highlighting t

Longitudinal Associations of Multimodal Core 1 Alzheimer Disease Biomarkers With Cognition in Aging and Preclinical Alzheimer Disease

BACKGROUND AND OBJECTIVES: Addressing the association between early-changing Alzheimer disease (AD) biomarkers and cognition is essential for characterizing preclinical AD. However, few studies have explored this relationship longitudinally, especially across multiple biomarker modalities. The aim of this study was to evaluate longitudinal associations of multimodal core 1 AD biomarkers with cogni
