Article Synopsis
- Reduced heart rate variability (HRV) and increased fatigue were observed in COVID-19 survivors compared to matched controls, with significant differences in several HRV metrics indicating impaired autonomic function.
- Moderate to vigorous physical activity (MVPA) and daily step count were significantly associated with HRV improvements in these survivors, suggesting that higher activity levels may benefit heart health post-infection.
- Fatigue in COVID-19 survivors correlated with lower levels of MVPA and fewer steps, indicating a complex relationship where physical activity could mediate the effects of HRV on fatigue levels.
Article Synopsis
- This study investigated tissue oxygen saturation (StO) in the vastus lateralis (VL) muscles of stroke survivors during a graded exercise test (GXT), hypothesizing that the paretic VL would have less reduction in StO than the non-paretic VL.
- Twenty-six chronic stroke survivors underwent a GXT while StO was measured using near infrared spectroscopy; results showed no initial difference in StO at rest between the paretic and non-paretic VL, but a significantly greater decrease in StO during the GXT in the non-paretic VL.
- The findings indicate that oxygen desaturation is less pronounced in the paretic VL during intense exercise, and highlight a positive correlation between the oxygen desaturation response in the
Masks are an effective tool in combatting the spread of COVID-19, but some people still resist wearing them and mask-wearing behavior has not been experimentally studied in the United States. To understand the demographics of mask wearers and resistors, and the impact of mandates on mask-wearing behavior, we observed shoppers (n = 9935) entering retail stores during periods of June, July, and August 2020. Approximately 41% of the June sample wore a mask.

Its effects on endothelial-dependent vasodilation are controversial in healthy subjects. The authors studied the effect of moderate short-term local hyperglycemia on forearm endothelium-dependent vasodilation in healthy volunteers.

We studied 4 NC designs: bifurcated nasal prongs (NPs) with O2 delivery and CO2 sensing in both NPs (Hudson), separate O2/CO2 NPs (Salter), and CO2 sensing in NPs with cloud O2 delivery outside the NPs via multi vents (Oridion) and dual vents (Medline). We hypothesized that design differences between NCs would influence O2 delivery and ETCO2 detection.
