Application of a Novel Endpoint Staging Framework: Proof of Concept in the AMBAR Study.

Background: A theoretical endpoint staging framework was previously developed and published, aligning outcomes (i.e., memory) to the stage of Alzheimer's disease (AD) in which a given outcome is most relevant (i.

Toward the optimized assessment of clinical outcomes in studies of novel treatments for Alzheimer's disease.

Introduction: Alzheimer's disease (AD) is characterized by a progressive decline in cognition and daily function, leading to a greater need for caregiver support. Clinical disease is segmented into a preclinical stage, mild cognitive impairment, and mild, moderate, and severe stages of Alzheimer's dementia. Although AD trials enroll participants at various stages of illness, treatment efficacy is often assessed using endpoints based on measures of outcomes that are held fixed across disease stages.

Survival after acute episodes of immune-mediated thrombotic thrombocytopenic purpura (iTTP) - cognitive functioning and health-related quality of life impact: a descriptive cross-sectional survey of adults living with iTTP in the United Kingdom.

Objectives: Immune-mediated thrombotic thrombocytopenic purpura (iTTP) is an ultra-rare life-threatening thrombotic microangiopathy affecting adults with unpredictable disease onset and acute presentation. This study aimed to describe the health-related quality of life (HRQoL), cognitive functioning and work productivity of survivors following acute episode(s) of iTTP in the United Kingdom (UK).

Methods: An online survey was developed in collaboration with the TTP Network.

Pre-post changes in main outcomes of medical rehabilitation in Germany: protocol of a systematic review and meta-analysis of individual participant and aggregated data.

Introduction: Multidisciplinary, complex rehabilitation interventions are an important part of the treatment of chronic diseases. However, little is known about the effectiveness of routine rehabilitation interventions within the German healthcare system. Due to the nature of the social insurance system in Germany, randomised controlled trials examining the effects of rehabilitation interventions are challenging to implement and scarcely accessible.
