Background: A dementia diagnosis can lead to a decline in cognitive, social, and physical health, but people with dementia can live meaningful lives and participate actively in society with psychosocial support. This single-arm, non-randomised feasibility study explored the feasibility and acceptability of a Comprehensive REsilience-building psychoSocial intervenTion (CREST) for people with dementia, their caregivers, General Practitioners (GPs), and the public.
Methods: Nine people with dementia and their primary caregivers living in the community (n = 9 dyads) completed the CREST intervention which had three components (cognitive stimulation therapy [CST], physical exercise, and dementia education).
Article Synopsis
- - The study presents a continuous water-window (WW) x-ray source operated for 120 minutes using a regenerative liquid bismuth jet with a diameter of 35-40 µm, injected into a vacuum.
- - Photon emissions were recorded at various peak wavelengths, with significant outputs at 4.1 nm and 4.3 nm from n=4-n=4 transitions, and at 2.8 nm from n=4-n=5 transitions, yielding a total photon emission rate in the range of 2.3-4.4 nm.
- - The findings indicate that the continuous operation of the liquid bismuth jet could enhance future extreme ultraviolet (EUV) lithography and x-ray microscopy technologies
Article Synopsis
- This study aimed to evaluate a new classification system for chronic venous obstruction (CVO) patients who have undergone successful medical procedures across 13 vascular centers from 2015 to 2019.
- Researchers analyzed the data of 1,033 CVO patients, classifying them into five categories based on the severity and location of their condition, and assessed stent deployment and complications alongside follow-up outcomes.
- Results showed that primary patency rates varied significantly among the classifications, with lower rates indicating more severe CVO, and identified key predictors of patency loss such as CVO type and the total number of stents used, suggesting the need for further validation of this classification system in future research.
Background: Nutcracker syndrome (NCS) describes the symptomatic compression of the left renal vein between the aorta and superior mesenteric artery. Whereas asymptomatic compression is a common radiological finding, patients with NCS can report a range of symptoms. There are no specific diagnostic criteria and interventions include a range of open surgical and endovascular procedures.
