65 normal, healthy people with a positive direct antiglobulin test (DAT) have been identified in a population of blood donors over a period of 14 years. 32 of them have been recalled for detailed study. A strong positive correlation with increasing age was noted, comparable to that seen in hospital patients with a positive DAT. No feature known to cause a positive DAT was identified in the healthy individuals, only 1 of whom went on to develop autoimmune haemolytic anaemia.

Prevalence of MRI lesions in men responding to a GP-led invitation for a prostate health check: a prospective cohort study.
BMJ Oncol

Urology, University College London Hospitals NHS Foundation Trust, London, UK.
Objective: In men with a raised prostate-specific antigen (PSA), MRI increases the detection of clinically significant cancer and reduces overdiagnosis, with fewer biopsies. MRI as a screening tool has not been assessed independently of PSA in a formal screening study. We report a systematic community-based assessment of the prevalence of prostate MRI lesions in an age-selected population.

January 2025
Background: Chronic neuropathic pain is a major health problem that adversely affects people's physical and mental well-being, as well as their quality of life. Percutaneous peripheral nerve stimulation (PNS) may offer a minimally invasive option earlier in the treatment continuum for adults with chronic neuropathic pain that is refractory to conventional medical management. We conducted a health technology assessment of PNS for adults with chronic neuropathic pain, which included an evaluation of effectiveness, safety, cost-effectiveness, the budget impact of publicly funding PNS, and patient preferences and values.

Transgender and gender-diverse (TGD) individuals face an elevated risk of cancer in comparison with the general population. This increased risk is primarily attributed to an imbalanced exposure to modifiable risk factors and a limited adherence to cancer screening programmes, stemming from historical social and economic marginalisation. Consequently, these factors contribute to poorer clinical outcomes in terms of cancer diagnosis and mortality.

School of Public Management, East China Normal University, Shanghai, China.
Objectives: This study aims to investigate whether social networks and physical exercise mediate the relationship between new and constant use of intelligent virtual assistants (IVAs) and cognitive function in older adults in China and explore the potential differences across living arrangements and education levels.
Methods: This study utilized nationally representative longitudinal data from 2018 to 2020, including a sample of 8343 older adults aged 60-80. A path-analytic model was employed to examine the relationship between IVAs use and cognitive function, as well as the mediating roles of social networks and physical exercise.
