Summary: Heart rate variability (HRV) indexes are useful for various applications and can be retrieved from the heart's electrical activity or mechanical signals recorded from the body's surface. However, the morphology of mechanical signals is strongly affected by body posture. This study investigated the feasibility of estimating HRV indexes from accelerometer and gyroscope data collected with a wearable IMU positioned at the xiphoid level.

Summary: The aim of this review is to provide a general overview on the rationale and potential benefits of melatonin for military personnel. Melatonin can help stabilize wounded individuals, especially in battlefield conditions where immediate access to medical care may be limited. It also has the potential to synchronize the neuro-cardio-respiratory systems, contributing to the oscillation of the heartbeat in synchrony with the breath. This field of investigation holds promise for future research.

Summary: Continuous measurement of heart rate variability using wearable devices is important for monitoring physiological status and preventing diseases. This study compared HRV features measured by a commercial device (Bora Band) and reference electrocardiography (ECG), and validated the use of ultra-short-term HRV as a substitute for short-term HRV features. The results showed agreement between PPG and ECG recordings for most HRV features, and the Bora Band provided valid and reliable HRV measurements in both short and ultra-short-term recordings.

Summary: In this study, a method using electroencephalogram (EEG) and heart rate variability (HRV) to evaluate human psychological states during the inhalation of aroma was proposed. The results showed that aroma has a significant effect on psychological states, with immediate response and gradual adaptation. The EEG and HRV indexes can be used to evaluate psychological states influenced by olfactory stimuli, especially for male participants in their 20-30s. The novelty of this research lies in the integration of biological indexes and emotion map to provide a more detailed picture of the psychological responses to olfactory stimuli.

Summary: The negative emotions following stressful life events can increase the risk of depressive symptoms and perceived stress. The process model of emotion regulation helps distinguish adaptive and maladaptive strategies to determine who may be at a higher risk of psychological health problems. Heart rate variability (HRV) may affect these relationships as it measures aspects of self-regulation, including emotion and behavioral regulation. The study found that higher vagally mediated HRV can buffer the adverse effects of expressive suppression on depressive symptoms, and weakly for perceived stress. There was no evidence for an interaction between cognitive reappraisal and HRV, but there was a significant negative association between cognitive reappraisal and depressive symptoms and perceived stress. Future research can investigate whether intervening on emotion regulation strategies or HRV can change these individual characteristics over time.

Summary: This study demonstrates that heart rate variability synchrony among operating surgeons is inversely correlated with the length of procedure, making it a feasible and objective marker for quantifying intraoperative teamwork. The findings suggest that HRV synchrony can be used to assess team cohesion and good teamwork, and it is also associated with team familiarity, stress levels, non-technical skills scores, and experience of team members.

Summary: This study explores the relationship between cycling training on a given day and the heart rate variability (HRV) and mood states obtained the following morning. The results show that higher training power leads to lower HFnu and higher LF/HF the next morning, indicating a negative impact on HRV. Furthermore, tougher training sessions are associated with lower mood the following day. Morning HRV is positively correlated with positive mood, suggesting a link between HRV and mood. Internal and external measures of training are also related to each other.

Summary: A multicenter study found that individuals with a triad of bodily pain, psychological distress, and sleep disturbance were at high risk for developing painful temporomandibular disorders (TMDs). Systematic examination revealed orofacial and systemic signs and symptoms in this triad phenotype, which could only be detected through multisystem assessment. Additionally, lower heart rate variability and higher resting heart rate were observed in the triad phenotype. Pain sensitivity, as measured by quantitative sensory testing, did not differ between groups. These findings emphasize the importance of comprehensive multisystem assessment and suggest that multisystem issues may provide critical information for understanding and managing TMDs and related pain conditions.

Summary: Dynamic visualizations like videos or animations are used to exchange information in various professional/academic contexts, and different instructional designs can improve learning outcomes. For novice learners, the effectiveness of static visualizations and reducing presentation speed in learning tactical scenes through dynamic visualizations depends on factors such as expertise level, type of depicted knowledge, and content complexity.

Summary: Gattinoni's equation is commonly used to calculate the mechanical power of ventilation, but it only calculates inspiratory power. Including PEEP in the equation is debated because PEEP does not contribute to power. Measuring the area within the pressure-volume loop accurately reflects the power received in a ventilation cycle and is not influenced by PEEP.

Summary: The study investigated ultra-short-term heart rate variability recordings under stabilization or post-stabilization periods in four overseas training camps for U-20 male national team futsal players. The results showed excellent agreement and high correlation coefficients for all time segments of HRVUST, suggesting that stabilization may be unnecessary for measuring morning resting LnRMSSD in overseas training camps among young adult futsal players. The findings indicate that 30 or 60-second LnRMSSD recordings can be used to evaluate daily cardiac-autonomic function during overseas training camps.
