Biological Response to Stress During Battlefield Trauma Training: Live Tissue Versus High-Fidelity Patient Simulator.

Tactical Combat Casualty Care (TCCC) training imposes psychophysiological stress on medics. It is unclear whether these stress levels vary with the training modalities selected. It is also unclear how stress levels could have an impact on medical performance and skill uptake.

Ambivalence over emotional expression and perceived social constraints as moderators of relaxation training and emotional awareness and expression training for irritable bowel syndrome.

Psychological treatments are generally beneficial for patients with irritable bowel syndrome (IBS), but patients' responses vary. A prior randomized controlled trial found that both relaxation training (RT) and emotional awareness and expression training (EAET) were superior to a waitlist control condition for IBS symptoms, quality of life, depression, and anxiety among IBS patients (Thakur et al., 2017).

Efficacy of a Spanish-Language Self-Administered Stress Management Training Intervention for Latinas Undergoing Chemotherapy.

Cancer patients often report increased stress during chemotherapy. Stress management training has been shown to reduce this adverse outcome, but few interventions exist for Spanish-speaking Hispanic and Latina women (Latinas).

The purpose of this study is to examine the effects of progressive muscle relaxation training program on sleep quality, sleep state, pain, and quality of life in patients who underwent pulmonary resection.

Dynamically Heterogeneous Relaxation of Entangled Polymer Chains.

Stress relaxation following deformation of an entangled polymeric liquid is thought to be affected by transient reforming of chain entanglements. In this work, we use single molecule techniques to study the relaxation of individual polymers in the transition regime from unentangled to entangled solutions. Our results reveal the emergence of dynamic heterogeneity underlying polymer relaxation behavior, including distinct molecular subpopulations described by a single-mode and a double-mode exponential relaxa...

Comparison of Compressive Stress-Relaxation Behavior in Osteoarthritic (ICRS Graded) Human Articular Cartilage.

Osteoarthritis (OA) is a common joint disorder found mostly in elderly people. The role of mechanical behavior in the progression of OA is complex and remains unclear. The stress-relaxation behavior of human articular cartilage in clinically defined osteoarthritic stages may have importance in diagnosis and prognosis of OA. In this study we investigated differences in the biomechanical responses among human cartilage of ICRS grades I, II and III using polymer dynamics theory. We collected 24 explants of hum...

Changes in mood, fatigue, sleep, cognitive performance and stress hormones among instructors conducting stressful military captivity survival training.

Numerous studies have examined the effects of captivity survival training on psychological and physiological function in trainees. In the present study we shifted the focus to instructors, and measured the effects that the delivery of training exerts on their levels of stress and performance. Because instructors are called upon to perform difficult duties (e.g., mock interrogations) under extreme conditions, we hypothesized that significant increases in psychological and physiological indices of stress woul...

The development and validation of a numerical integration method for non-linear viscoelastic modeling.

Compelling evidence that many biological soft tissues display both strain- and time-dependent behavior has led to the development of fully non-linear viscoelastic modeling techniques to represent the tissue's mechanical response under dynamic conditions. Since the current stress state of a viscoelastic material is dependent on all previous loading events, numerical analyses are complicated by the requirement of computing and storing the stress at each step throughout the load history. This requirement quick...

Effects of heart rate variability biofeedback training in athletes exposed to stress of university examinations.

Heart rate variability biofeedback (HRV-BFB) training, a method whereby one controls an unusually low breathing rate to reach cardiac coherence, has been shown to reduce anxiety and improve cardiac autonomic markers in diseased people, but much less is known about HRV-BFB benefits in healthy people. Here we investigated potential benefits in young competitors experiencing stress during university examinations as well as persistence of benefits after HRV-BFB training cessation.

Predicting acoustic relaxation absorption in gas mixtures for extraction of composition relaxation contributions.

The existing molecular relaxation models based on both parallel relaxation theory and series relaxation theory cannot extract the contributions of gas compositions to acoustic relaxation absorption in mixtures. In this paper, we propose an analytical model to predict acoustic relaxation absorption and clarify composition relaxation contributions based on the rate-determining energy transfer processes in molecular relaxation in excitable gases. By combining parallel and series relaxation theory, the proposed...

The interaction of fatigue cracks with a residual stress field using thermoelastic stress analysis and synchrotron X-ray diffraction experiments.

This article presents an experimental study on the fatigue behaviour of cracks emanating from cold-expanded holes utilizing thermoelastic stress analysis (TSA) and synchrotron X-ray diffraction (SXRD) techniques with the aim of resolving the long-standing ambiguity in the literature regarding potential relaxation, or modification, of beneficial compressive residual stresses as a result of fatigue crack propagation. The crack growth rates are found to be substantially lower as the crack tip moved through the...

Exercise training induces eNOS coupling and restores relaxation in coronary arteries of heart failure rats.

Exercise training (ET) has emerged as a non-pharmacological therapy for cardiovascular diseases because of its helpful milieu for improving vascular function. The aim of the present study was to assess whether ET reverses the alterations in vascular reactivity observed in heart failure (HF)-related coronary arteries and to elucidate the molecular mechanisms involved in these adjustments. Male Wistar rats were subjected to either coronary artery ligation or sham operation (SO). Four weeks after the surgery, ...

Exposure therapy for youth with anxiety: Utilization rates and predictors of implementation in a sample of practicing clinicians from across the United States.

Exposure therapy is a highly effective, evidence-based treatment technique for children and adolescents with anxiety disorders. Regardless, therapists in the community are reported to use exposure relatively rarely compared with other approaches. The goal of the present study was to identify how practicing clinicians treat youth with anxiety disorders across the United States and what factors contribute to their use of exposure therapy. Recruited from public directories, 257 private practice therapists who ...

Negative supercoiling of DNA by gyrase is inhibited in Salmonella enterica serovar Typhimurium during adaptation to acid stress.

DNA in intracellular Salmonella enterica serovar Typhimurium relaxes during growth in the acidified (pH 4 to 5) macrophage vacuole and DNA relaxation correlates with upregulation of Salmonella genes involved in adaptation to the macrophage environment. Bacterial ATP levels did not increase during adaptation to acid pH unless the bacterium was deficient in MgtC, a cytoplasmic-membrane-located inhibitor of proton-driven F1 F0 ATP synthase activity. Inhibiting ATP binding by DNA gyrase and topo IV with novobio...

Motor imagery of voluntary muscle relaxation of the foot induces a temporal reduction of corticospinal excitability in the hand.

The object of this study was to clarify how the motor imagery of foot muscle relaxation influences corticospinal excitability for the ipsilateral hand. Twelve participants volitionally relaxed their right foot from a dorsiflexed position (actual relaxation), or imaged the same movement (imagery relaxation) in response to an auditory cue. Transcranial magnetic stimulation (TMS) was delivered to the hand area of the left primary motor cortex at different time intervals after an auditory cue. Motor evoked pote...

Crisis-counselor perceptions of job training, stress, and satisfaction during disaster recovery.

The United States Crisis Counseling Assistance and Training Program (CCP; authorized by the Robert T. Stafford Disaster Relief and Emergency Assistance Act, 1974/2013) aims to provide disaster-recovery support to communities following natural or human-caused disasters through outreach. Job satisfaction among the crisis counselors the CCP employs may affect the delivery of outreach services to survivors and their communities. The present study was conducted to gain insight into CCP crisis counselors' experie...

Stress, seizures, and epilepsy: Patient narratives.

In epilepsy, individual seizures can be triggered by a variety of external and internal stimuli. One of the most common trigger factors reported by patients is stress. However prevalent, stress-related triggering of episodes seems underappreciated in epilepsy for various reasons, and its misinterpretation often leads to other diagnoses, e.g., psychogenic nonepileptic seizures (PNES) or normal reactions. This article illustrates the significant role of stress as a seizure-provoking factor by referring to nin...

Magnetic resonance imaging relaxation time in Alzheimer's disease.

The magnetic resonance imaging (MRI) relaxation time constants, T1 and T2, are sensitive to changes in brain tissue microstructure integrity. Quantitative T1 and T2 relaxation times have been proposed to serve as non-invasive biomarkers of Alzheimer's disease (AD), in which alterations are believed to not only reflect AD-related neuropathology but also cognitive impairment. In this review, we summarize the applications and key findings of MRI techniques in the context of both AD subjects and AD transgenic m...

Resilience Training for Work-related Stress Among Health Care Workers: Results of a Randomized Clinical Trial Comparing In-person and Smartphone-delivered Interventions.

One Session of Autogenic Training Increases Acute Subjective Sexual Arousal in Premenopausal Women Reporting Sexual Arousal Problems.

Below average heart rate variability (HRV) has been associated with sexual arousal dysfunction and overall sexual dysfunction in women. Autogenic training, a psychophysiologic relaxation technique, has been shown to increase HRV. In a recent study, sexually healthy women experienced acute increases in physiologic (ie, genital) and subjective sexual arousal after 1 brief session of autogenic training.

Cholecystokinin Induces esophageal longitudinal muscle contraction and transient lower esophageal sphincter relaxation in healthy humans.

Cholecystokinin (CCK) is known to cause lower esophageal sphincter (LES) relaxation through the activation of inhibitory motor neurons. Recent studies show that the longitudinal muscle contraction (LMC) related axial stretch may play a role in the LES relaxation. The aim of our study was to determine whether the CCK induced LES relaxation and identify the characteristics of associated LMC in humans. Nine healthy volunteers (5F, 40 + 12 years) received escalating doses of CCK-octapeptide (5, 10, 20 and 40 ng...

Long-range stress correlations in viscoelastic and glass-forming fluids.

A simple and rigorous approach to obtain stress correlations in viscoelastic liquids (including supercooled liquid and equilibrium amorphous systems) is proposed. The long-range dynamical correlations of local shear stress are calculated and analyzed in 2-dimensional space. It is established how the long-range character of the stress correlations gradually emerges as the relevant dynamical correlation length l grows in time. The correlation range l is defined by momentum propagation due to acoustic waves an...

Voluntary exercise and depression-like behavior in rodents - are we running in the right direction?

Acute or chronic exposure to stress can increase the risk to develop major depressive disorder, a severe, recurrent and common psychiatric condition. Depression places an enormous social and financial burden on modern society. Although many depressed patients are treated with antidepressants, their efficacy is only modest, underscoring the necessity to develop clinically-effective pharmaceutical or behavioral treatments. Exercise training produces beneficial effects on stress-related mental disorders, indic...

Estimates of Tibial Shock Magnitude in Men and Women at the Start and End of a Military Drill Training Program.

Foot drill is a key component of military training and is characterized by frequent heel stamping, likely resulting in high tibial shock magnitudes. Higher tibial shock during running has previously been associated with risk of lower limb stress fractures, which are prevalent among military populations. Quantification of tibial shock during drill training is, therefore, warranted. This study aimed to provide estimates of tibial shock during military drill in British Army Basic training. The study also aimed...
