Heart rate variability reveals that a decrease in parasympathetic (‘rest-and-digest’) activity dominates autonomic stress responses in a free-living seabird

Martina S. Müller, Alexei L. Vyssotski, Maki Yamamoto, Ken Yoda

Comparative Biochemistry and Physiology Part A: Molecular & Integrative... > 2017 > 212 > C > 117-126

The autonomic stress response, often referred to as the ‘fight-or-flight’ response, is a highly conserved physiological reaction to stress in vertebrates that occurs via a decrease in parasympathetic (PNS) activity, which promotes self-maintenance ‘rest and digest’ processes, and an increase in sympathetic (SNS) activity, which prepares an animal for danger (‘fight-or-flight’). Though the PNS and...

Potassium supplementation and heart rate: A meta-analysis of randomized controlled trials

L. Gijsbers, F.J.M. Mölenberg, S.J.L. Bakker, J.M. Geleijnse

Nutrition, Metabolism and Cardiovascular Diseases > 2016 > 26 > 8 > 674-682

Increasing the intake of potassium has been shown to lower blood pressure, but whether it also affects heart rate (HR) is largely unknown. We therefore assessed the effect of potassium supplementation on HR in a meta-analysis of randomized controlled trials.We searched PubMed (1966–October 2014) for randomized, placebo-controlled trials in healthy adults with a minimum duration of two weeks in which...

Elevated resting heart rate in heart transplant recipients: innocent bystander or adverse prognostic indicator?

S. Blake Wachter, Sean P. McCandless, Edward M. Gilbert, Gregory J. Stoddard, more

Clinical Transplantation > 29 > 9 > 829 - 834

BackgroundThe elevated baseline heart rate (HR) of a heart transplant recipient has previously been considered inconsequential. However, we hypothesized that a resting HR above 100 beats per minute (bpm) may be associated with morbidity and mortality. MethodsThe U.T.A.H. Cardiac Transplant Program studied patients who received a heart transplant between 2000 and 2011. Outpatient HR values for each...

Ictal tachycardia: The head–heart connection

Katherine S. Eggleston, Bryan D. Olin, Robert S. Fisher, K.S. Eggleston, more

Seizure: European Journal of Epilepsy > 2014 > 23 > 7 > 496-505

Epileptic seizures can lead to changes in autonomic function affecting the sympathetic, parasympathetic, and enteric nervous systems. Changes in cardiac signals are potential biomarkers that may provide an extra-cerebral indicator of ictal onset in some patients. Heart rate can be measured easily when compared to other biomarkers that are commonly associated with seizures (e.g., long-term EEG), and...

Autonomic Neuroscience: Basic and Clinical > 2013 > 178 > 1-2 > 103-110

It is urgently aimed in prenatal medicine to identify pregnancies, which develop life-threatening preeclampsia prior to the manifestation of the disease. Here, we use recurrence-based methods to distinguish such pregnancies already in the second trimester, using the following cardiovascular time series: the variability of heart rate and systolic and diastolic blood pressures. We perform recurrence...

Is blunted cardiovascular reactivity in depression mood-state dependent? A comparison of major depressive disorder remitted depression and healthy controls

Kristen Salomon, Lauren M. Bylsma, Kristi E. White, Vanessa Panaite, more

International Journal of Psychophysiology > 2013 > 90 > 1 > 50-57

Prior work has repeatedly demonstrated that people who have current major depression exhibit blunted cardiovascular reactivity to acute stressors (e.g., Salomon et al., 2009). A key question regards the psychobiological basis for these deficits, including whether such deficits are depressed mood-state dependent or whether these effects are trait-like and are observed outside of depression episodes...

The impact of anxiety on postural control: CO₂ challenge model

Alexander N. W. Taylor, Daniel C. Low, Gregory S. Walsh, Nigel Holt

Psychophysiology > 60 > 3 > n/a - n/a

Anxiety and balance and postural control are linked via common neural pathways, such as the parabrachial nucleus network. A laboratory‐based model of general anxiety disorder (GAD) using the CO₂ challenge, has potential to be used to observe this relationship, potentially mimicking subjective, autonomic, and neuropsychological features of GAD. The current feasibility study used the CO₂ challenge to...

High counting of circulating tumor cells in blood is not directly related to metastasis

Xiaohui Zhao, Ziang Qi, Ziao Gao, Hao He

Cytometry Part A > 103 > 1 > 82 - 87

Circulating tumor cells (CTCs) in blood flow have been believed as an essential biomarker of cancer. The technologies of in vitro and in vivo CTC enrichment and detection suggest although CTCs might play a role of “seed” in metastasis, only the minority of CTCs, probably in the form of CTC clusters, hold the potential to develop a tumor in organs. The detected amount of CTCs might be solely an indicator...

In the parvocellular part of paraventricular nucleus, glutamatergic and GABAergic neurons mediate cardiovascular responses to AngII

Ali Rastegarmanesh, Bahar Rostami, Ali Nasimi, Masoumeh Hatam

Synapse > 77 > 2 > n/a - n/a

Angiotensinergic, GABAergic, and glutamatergic neurons are present in the parvocellular region of the paraventricular nucleus (PVNp). It has been shown that microinjection of AngII into the PVNp increases arterial pressure (AP) and heart rate (HR). The presence of synapses between the angiotensinergic, GABAergic, and glutamatergic neurons has been shown in the PVNp. In this study, we investigated...

Development and validation of a deep learning model to diagnose COVID‐19 using time‐series heart rate values before the onset of symptoms

Heewon Chung, Hoon Ko, Hooseok Lee, Dong Keon Yon, more

Journal of Medical Virology > 95 > 2 > n/a - n/a

One of the effective ways to minimize the spread of COVID‐19 infection is to diagnose it as early as possible before the onset of symptoms. In addition, if the infection can be simply diagnosed using a smartwatch, the effectiveness of preventing the spread will be greatly increased. In this study, we aimed to develop a deep learning model to diagnose COVID‐19 before the onset of symptoms using heart...

When closeness is effortful: Teachers’ physiological activation undermines positive effects of their closeness on student emotions

Tim Mainhard, Monika H. Donker, Tamara Gog

British Journal of Educational Psychology > 92 > 4 > 1384 - 1402

Background Student perceptions of teachers’ interpersonal closeness positively affect their emotions. If closeness is, however, effortful for the teacher (i.e., emotional labour, signalling less genuine closeness), this may undermine these positive effects. We tested this assumption by using student reports and external observations of teacher closeness and ambulant measures of teacher heart rate,...

New insights on the correspondence between subjective affective experience and physiological responses from representational similarity analysis

Carlos Ventura‐Bort, Julia Wendt, Mathias Weymar

Psychophysiology > 59 > 11 > n/a - n/a

Classical views suggest that experienced affect is related to a specific bodily response, whereas recent perspectives challenge this view postulating that similar affective experiences rather evoke different physiological responses. To further advance this debate in the field, we used representational similarity analysis to investigate the correspondence between subjective affect (arousal and valence...

Physiological responses of narwhals to anthropogenic noise: A case study with seismic airguns and vessel traffic in the Arctic

Terrie M. Williams, Susanna B. Blackwell, Outi Tervo, Eva Garde, more

Functional Ecology > 36 > 9 > 2251 - 2266

Limited polar geographical range, narrowly defined migratory routes, and deep‐diving behaviours make narwhals exceptionally vulnerable to anthropogenic disturbances including oceanic noise. Although behavioural studies indicate marked responses of cetaceans to disturbance, the link between fear reactions and possible injury from noise exposure is limited for most species. To address this, we deployed...

Early physiological indicators of narcissism and self‐esteem in children

Eddie Brummelman, Milica Nikolić, Barbara Nevicka, Susan M. Bögels

Psychophysiology > 59 > 10 > n/a - n/a

A common belief is that narcissism is a manifestation of high self‐esteem. Here, we argue that self‐esteem and narcissism are fundamentally distinct and have unique early physiological indicators. We hypothesized that children predisposed to narcissism would show elevated, whereas children predisposed to high self‐esteem would show lowered, physiological arousal in social‐evaluative contexts. We tested...
