re, through the effects of behavioral and psychological symptoms of dementia on the caregivers' levels of activity restriction and frequency of pleasant activities. Our manuscript provides additional support for the pleasant events and activity restriction model (Mausbach et al., 2011; Chattillion et al., 2013), by highlighting the importance of considering caregiving stressors as a source of caregivers' activity restriction in the theoretical framework of the model.
Scar and vulnerability models assert that increased psychopathology may predict subsequent executive functioning (EF) deficits (and vice versa) over protracted timescales, yet most prior work on this topic has been cross-sectional. Thus, we tested the within- and between-person relations between EF, depression, and anxiety.

Older adult participants (n=856) were assessed across four waves, approximately 2years apart. Performance-based EF and caregiver-rated symptom measures were administered. Bivariate latent change score and random-intercept cross-lagged panel models were conducted.

Within persons, random-intercept cross-lagged panel models revealed that prior greater depression forecasted lower subsequent EF, and vice versa (d=-0.292 vs. -0.292). Bivariate dual latent change score models showed that within-person rise in depression predicted EF decreases, and vice versa (d=-0.245 vs. -0.245). No within-person, cross-lagged, EF-anxiety relations emerged. selleck compound Further, significant negative between-person EF-symptom relations were observed (d=-0.264 to -0.395).

Prospective, within-person findings offer some evidence for developmental scar and vulnerability models.

The application of a 4K display resolution three-dimensional exoscope system (Vitom 3D) was evaluated to determine the feasibility of adopting the system in ENT surgery in the coronavirus disease 2019 era and beyond.

Eighteen ENT surgeons performed structured otological tasks on fresh-frozen sheep heads using the Vitom 3D. Structured feedback of the participants' experience was analysed.

Seventy-four per cent and 94 per cent of participants reported that the Vitom 3D was ergonomic and comfortable to use respectively. Whilst colour fidelity and image quality were very good, 50 per cent of participants reported image distortion and pixilation at the highest magnification. All participants agreed that there was an increased educational value to exoscope technology. Half the participants preferred the microscope over the Vitom 3D for fine otological work, which may reflect the learning curve.

The Vitom 3D exoscope is a promising and viable alternative for performing otological surgery when using full personal protective equipment in the coronavirus disease 2019 era.

The aim of this study was to examine antioxidant responses to high-intensity interval exercise following acute L-Cit supplementation. Nine young men (21 ± 1 years) participated in a double-blind crossover study in which they received 12 g of L-Cit and placebo (PL) an hour prior to high-intensity interval exercise on two occasions, separated by a seven-day washout period. Blood samples were obtained before (PRE), immediately after (IP), 10 (10P), and 30 min after exercise (30P) from the cubital vein using standard procedures. Serum concentrations of superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT), and NO metabolites (NOx) were measured. The exercise protocol significantly elevated SOD (p = 0.01) and GPx (p = 0.048) from PRE to 10P in the L-Cit group with greater changes than the PL group. CAT concentrations increased IP (p = 0.014) and remained elevated at 10P (p = 0.03) and 30P (p = 0.015) in both the L-Cit and PL conditions. NOx concentrations increased IP (p = 0.05) in the L-Cit group with greater changes than PL group in PRE to IP, PRE to 10P, and PRE to 30P (p less then 0.05). Our data indicate that L-Cit supplementation (single 12 g dose pre-exercise) induces improvements in antioxidant markers following a session of high-intensity interval exercise in young men.
The Montreal Cognitive Assessment (MoCA) is a commonly used cognitive outcome in stroke trials. However, it may be insufficiently sensitive to detect impairment in high-functioning stroke survivors. The National Institutes of Health (NIH) Toolbox Cognition Battery (NIHTB-CB), a 30-min comprehensive tablet-based cognitive assessment, may be a better choice to characterize cognitive issues in this cohort.

We compared MoCA and NIHTB-CB performance in young stroke survivors (18-55 years) with excellent functional outcomes (modified Rankin Scale 0-1) reporting subjective cognitive complaints to that of age-matched healthy controls. We recruited 53 stroke survivors and 53 controls. We performed a sensitivity analysis in those participants with normal MoCA scores (≥26).

Median MoCA scores were not significantly different between stroke survivors (27.0 vs. 28.0) and healthy controls. Mean T scores for NIHTB-CB fluid (44.9 vs. 54.2), crystallized (53.8 vs. 60.0), and total cognition (49.1 vs. 58.4) components were significantly lower in stroke survivors compared to healthy controls (p < 0.001 for all). In participants scoring within normal range (≥26) on the MoCA, NIHTB-CB scores for all components remained significantly lower in stroke survivors.

In young stroke survivors with excellent functional outcomes and subjective cognitive complaints, the NIHTB-CB, but not the MoCA, was able to detect differences in cognitive performance between stroke survivors and healthy controls. The NIHTB-CB may be a suitable outcome measure for cognition in clinical trials examining higher-functioning young stroke survivors.
