Contactless radar-based heart rate estimation in palliative care - a feasibility study and possible use in symptom management.

Background: Heart rate (HR) monitoring is a medical standard to provide information about a patient's health status. In palliative care, relationship and social engagement are crucial therapeutic concepts. For fear of disrupting communication, social contact, and care, continuous HR monitoring is underutilised despite its potential to inform on symptom burden and therapeutic effects.

Previous studies have found that threatening stimuli are more readily perceived and more intensely experienced when presented during cardiac systole compared with diastole. Also, threatening stimuli are judged as physically closer than neutral ones. In a pre-registered study, we tested these effects and their interaction using a naturalistic (interactive and three-dimensional) experimental design in immersive virtual reality: we briefly displayed threatening and non-threatening animals (four each) at varying distances (1.

Background: Heart rate variability (HRV) is a marker of autonomic function. However, the reliability of short-term HRV measurement in individuals with combat-related traumatic injury (CRTI) remains undetermined.
Methods: An intra- and inter-rater reliability study was conducted using a subsample (n = 35) of British servicemen with CRTI enrolled in the ongoing ADVANCE study.
Emotion perception through the nose: how olfactory emotional cues modulate the perception of neutral facial expressions in affective disorders.

Humans can decode emotional states from the body odors of the conspecifics and this type of emotional communication is particularly relevant in conditions in which social interactions are impaired, as in depression and social anxiety. The present study aimed to explore how body odors collected in happiness and fearful conditions modulate the subjective ratings, the psychophysiological response and the neural processing of neutral faces in individuals with depressive symptoms, social anxiety symptoms, and healthy controls (N = 22 per group). To this aim, electrocardiogram (ECG) and HD-EEG were recorded continuously.

Article Synopsis
- This study aimed to validate a 14-second femoral arterial waveform method for measuring heart rate variability (HRV) against the standard 300-second ECG method.
- Conducted with 100 adult servicemen, strong correlations were found between the two methods for heart rate (HR) and RMSSD, but HR showed significant differences while RMSSD did not.
- The results suggest that the 14-second PWV-derived RMSSD is reliable compared to the ECG gold standard, although heart rate measurements vary based on the method used.
