Predicting regional tau accumulation with machine learning-based tau-PET and advanced radiomics.

Introduction: Alzheimer's disease is partially characterized by the progressive accumulation of aggregated tau-containing neurofibrillary tangles. Although the association between accumulated tau, neurodegeneration, and cognitive decline is critical for disease understanding and clinical trial design, we still lack robust tools to predict individualized trajectories of tau accumulation. Our objective was to assess whether brain imaging biomarkers of flortaucipir-positron emission tomography (PET), in combination with clinical and genomic measures, could predict future pathological tau accumulation.

Latest developments in arthroplasty for hip fractures.

Hip fractures pose a major global health challenge, leading to high rates of morbidity and mortality, particularly among the elderly. With an ageing population, the incidence of these injuries is rising, exerting significant pressure on healthcare systems worldwide. Despite substantial research aimed at establishing best practice, several key areas remain the subject of ongoing debate.

Trend in incidence and clinicopathological characteristics of prostate cancer in Northern Tanzania: analysis from a population based cancer registry data 2015-2021.

Background: Globally, prostate cancer is a common disease among men. However, limited epidemiological data exists regarding prostate cancer in Tanzania. Consequently, there is insufficient evidence to convince policymakers of the need to combat this health issue.

Periprosthetic joint infection of the hip.

Aims: The number of revision arthroplasties being performed in the elderly is expected to rise, including revision for infection. The primary aim of this study was to measure the treatment success rate for octogenarians undergoing revision total hip arthroplasty (THA) for periprosthetic joint infection (PJI) compared to a younger cohort. Secondary outcomes were complications and mortality.
