Remote magnetic navigation (RMN) can be safely and effectively utilized in patients with difficult cardiac arrhythmias and complex anatomy. Interruption of the inferior vena cava (IVC) is a rare congenital abnormality that results in the inability to use conventional femoral access in patients that require interventional procedures. The present case demonstrates the feasibility of left atrial flutter ablation using RMN via jugular approach in a patient with interruption of IVC.

Background: Accumulation of β-amyloid (Aβ) plaque in the brain is a pathological hallmark of Alzheimer's Disease (AD). We recently reported that the application of mild magnetic hyperthermia is feasible to target and disrupt Aβ plaques by means of generating localized heat on the surface of magnetic nanoparticles (MNPs) targeted to Aβ aggregates in response to a remotely applied alternating magnetic field (AMF) (Nanomedicine:NBM, 2021). The objective of the current study is to demonstrate the feasibility of mild magnetic hyperthermia stimulation (MNP/AMF) in clearing Aβ deposits in vivo using 5xFAD mice, a well-established transgenic AD mouse model.

Background: Dementia-related biomarkers can detect pathology years before clinical diagnostic criteria are met. Understanding the relationship between biomarkers and early cognitive changes is crucial as disease-modifying therapies may have maximum benefits when delivered early. We aimed to demonstrate the utility of remote computerised cognitive tests in a large cohort of cognitively normal older individuals, comparing these to standard in-person assessments and investigating their associations with biomarkers.

Background: Remote unsupervised cognitive assessments have the potential to complement and facilitate cognitive assessment in clinical and research settings.
Method: Here we evaluate the usability, validity and reliability of unsupervised remote memory assessments via mobile devices (see Figure 1) in individuals without dementia from the Swedish BioFINDER-2 study and explore their prognostic utility regarding future cognitive decline in combination with a plasma marker for p-tau217.
Result: Usability was rated positively.

Background: Our studies show that the small non-coding RNA, mir20a-3p, is neuroprotective for stroke in the acute phase and also attenuates long term cognitive decline in middle-aged female rats. Cognitive decline due to vascular diseases, such as stroke, is associated with secondary neurodegeneration in cortex and limbic structures. In this study, we assessed the volume of white matter, ventricles and regional diffusion-weighted MR imaging measures to delineate pathological tissue characteristics from the postmortem brain of stroke rats.

Background: Each year, millions of Americans experience mild traumatic brain injury (mTBI). Current research on the long-term effects of mTBI vary considerably. Several mechanisms linking mTBI to dementia have been proposed including amyloid plaque formation and cerebrovascular injury following mTBI.
