Plasma phosphorylated tau biomarkers open unprecedented opportunities for identifying carriers of Alzheimer's disease pathophysiology in early disease stages using minimally invasive techniques. Plasma p-tau biomarkers are believed to reflect tau phosphorylation and secretion. However, it remains unclear to what extent the magnitude of plasma p-tau abnormalities reflects neuronal network disturbance in the form of cognitive impairment.

Z boson events at the Large Hadron Collider can be selected with high purity and are sensitive to a diverse range of QCD phenomena. As a result, these events are often used to probe the nature of the strong force, improve Monte Carlo event generators, and search for deviations from standard model predictions. All previous measurements of Z boson production characterize the event properties using a small number of observables and present the results as differential cross sections in predetermined bins.

Introduction: Elbow ailments are common, but conventional treatment modalities have shortcomings, offering only interim pain relief rather than targeting the underlying pathophysiology. The last two decades have seen a marked increase in the use of autologous peripheral blood-derived orthobiologics (APBOs), such as platelet-rich plasma (PRP), to manage elbow disorders. Platelet-rich plasma (PRP) is the most widely used APBO, but its efficacy remains debatable.

It is unknown whether this applies to patients with low-risk disease following simple hysterectomy.
Methods: Among patients who underwent simple hysterectomy in the Simple Hysterectomy And PElvic node assessment trial, univariate and multivariate Cox models were used to assess the association of minimally invasive versus open surgery with clinical outcomes, including pelvic and extra-pelvic recurrence-free survival, overall recurrence-free survival, and overall survival.

In this paper, the European Academy of Dermatology and Venereology (EADV) Task Force on Quality of Life (QoL) and Patient-Oriented Outcomes presents its position statements on health-related (HR) QoL assessment in epidermolysis bullosa (EB). The EADV TF on QoL and Patient-Oriented Outcomes recommends the use of the EB-specific instrument QOLEB in patients over the age of 10 years and, in addition to the QOLEB, the use of iscorEB-p in moderate-to-severe EB; the IntoDermQoL proxy instrument with its EB-specific module should be used in children aged under 5 years. The EB-specific instrument iscorEB-p, and the dermatology-specific instrument CDLQI may measure HRQoL in children with EB aged from 5 to 10 years.

Background: The information and decision support needs required to embed a patient-centred strategy are challenging, as several haemodialysis vascular access strategies are possible with significant differences in short- and long-term outcomes of potential treatment options. We aimed to explore and describe stakeholder perspectives on information needs when making decisions about vascular access (VA) for haemodialysis.
Methods: We performed thematic analysis of seven (six online, one in person) focus group discussions including transcripts, post-it phrases and text responses with 14 patients and 12 vascular access professionals (four nephrologists, three surgeons and five nurses - Vascular access nurse specialists/Education and dialysis nurses) who participated in at total of six online and one in person focus group.

Introduction: Antisense oligonucleotides (ASOs) have shown promise in reducing amyloid precursor protein (APP) levels in neurons, but their effects in astrocytes, key contributors to neurodegenerative diseases, remain unclear. This study evaluates the efficacy of APP ASOs in astrocytes derived from an individual with Down syndrome (DS), a population at high risk for Alzheimer's disease (AD).
Methods: Human induced pluripotent stem cells (hiPSCs) from a healthy individual and an individual with DS were differentiated into astrocytes.
Digital health interventions (DHIs), such as apps, websites and wearables, are being presented as solutions or enablers to manage the burden of cardiometabolic disease in healthcare. However, the potential benefits of DHIs may not be reaching the most in-need populations, who may face intersecting barriers to accessing health services and digital solutions. The Digital Interventions for South Asians in Cardiometabolic Disease (DISC) study used a mixed-method approach to focus on people of a South Asian background, a high-risk group for cardiometabolic disease.
