Feasibility and Acceptability of a Virtual "Dementia Awareness for Caregivers" Course in Brazil and India.

Objective: To establish whether a virtual dementia awareness course is feasible for caregivers of people with dementia in Brazil and India.

Methods: A pre/posttest single group, multisite feasibility study, mixed methods exploratory design was applied. Primary caregivers of people with dementia in Brazil and India took a 3 to 4-hour course adapted for online delivery, with 10 to 15 caregivers.

Functional differences between rodent and human PD-1 linked to evolutionary divergence.

Mechanistic understanding of the inhibitory immunoreceptor PD-1 is largely based on mouse models, but human and mouse PD-1 share only 59.6% amino acid identity. Here, we found that human PD-1 is more inhibitory than mouse PD-1, owing to stronger interactions with the ligands PD-L1 and PD-L2 and more efficient recruitment of the effector phosphatase Shp2.

Irritability in stroke: a protocol for a prospective study.

Background: Poststroke irritability (PSI) is common among stroke survivors and can lead to a poor quality of life, difficulties in social interactions, criticism from caregivers, and caregiver stress. The planned study will evaluate the clinical, neuropsychological, and magnetic resonance imaging (MRI) correlates of PSI in a cohort of stroke survivors. In addition, the study will examine the 15-month progression of PSI.

The Effect of a Non-Surgical Adhesive Bone Conduction Device on Temporal Processing Performance in Adults with Single Sided Deafness: A Pilot Study.

Background: There is a dearth of information on the effects of bone conductive devices on temporal processing in individuals with single-sided deafness (SSD). This study investigates the effect of an adhesive bone conductive device on temporal processing in adults with SSD.

Methods: A prospective cohort study of temporal processing in adults with SSD was undertaken.

Loss of empathy in stroke.

Background: Loss of empathy (LoE) is common among stroke survivors, yet often undiagnosed and thus untreated. LoE is related to the loss of a caring marital relationship, higher care burden and poorer quality of life in carers. The present study will evaluate the clinical and MRI correlates of LoE in a cohort of stroke survivors.
