Defense reactions to threatening situations are vital adaptations to stress that protect organisms from injury and ensure survival. We retrospectively investigated the role of peritraumatic dissociation (PD) in the occurrence of severe psychopathology and dissociative patterns of reactions in borderline personality disorder (BPD). We recruited 28 patients with a clinical diagnosis of BPD and 15 healthy controls. The BPD group was divided according to the level of PD (low vs. high): BPD and PD (n = 15) and BPD only (n = 13)...

: Higher levels of self-control in decision making have been linked to better psychosocial and physical health. A similar link to health outcomes has been reported for heart rate variability (HRV), a marker of physiological flexibility. Here, we sought to link these two, largely separate, research domains by testing the hypothesis that greater HRV would be associated with better dietary self-control in humans. Specifically, we examined whether total HRV at sedentary rest (measured as the standard deviation of normal-to-normal intervals, SDNN) can serve as a biomarker for the neurophysiological adaptability that putatively underlies self-controlled behavior...

OBJECTIVES: The effects of mind-body exercises on individuals with chronic illnesses have attracted increasing attention. However, little effort had been made to systematically review the effects of these mind-body exercises on individuals with Parkinson's disease (PD). This review aimed to appraise the current evidence of the effects of mind-body exercises on the physiological and psychological outcomes for the PD population. DESIGN: Systematic review and meta-analysis of randomized controlled trials...

Pediatric elimination disorders are common in childhood, yet psychosocial correlates are generally unclear. Given the physiological concomitants of both enuresis and encopresis, and the fact that many children with elimination disorders are initially brought to their primary care physician for treatment, medical evaluation and management are crucial and may serve as the first-line treatment approach. Scientific investigation on psychological and behavioral interventions has progressed over the past couple of decades, resulting in the identification of effective treatments for enuresis and encopresis...

Contemporary theory suggests that prefrontal cortex (PFC) function is associated with individual variability in the psychobiology of the stress response. Advancing our understanding of this complex biobehavioral pathway has potential to provide insight into processes that determine individual differences in stress susceptibility. The present study used functional magnetic resonance imaging to examine brain activity during a variation of the Montreal Imaging Stress Task (MIST) in 53 young adults. Salivary cortisol was assessed as an index of the stress response, trait anxiety was assessed as an index of an individual's disposition toward negative affectivity, and self-reported stress was assessed as an index of an individual's subjective psychological experience...

Chronic psychological stress cause erectile dysfunction (ED). Considering recent evidence that tumor necrosis factor-α (TNF-α) levels are increased in serum of patients with ED, the present study investigated the effects of infliximab (a TNF-α blocker) on endothelial nitric oxide synthase (eNOS) and neuronal NOS (nNOS) immunoreactivity of rat penile corpus cavernosum in unpredictable chronic mild stress (UCMS). Male adult rats were randomly divided into three groups (n=8 per group): Control, UCMS and UCMS+infliximab...

Most of the research on public perceptions of people with addictive disorders has focused on alcohol and illicit drugs, rather than addiction to behavioral activities. To expand the range of addictive behaviors and types of perceptions studied, we designed the present study to assess the lay public's definitions of and willingness to affiliate with people described as addicted to 1 of 2 specific behaviors (i.e., pornography or gambling) or 1 of 3 specific substances (i.e., alcohol, marijuana, or heroin). A nationwide convenience sample (N = 612) of American adults completed online questionnaires during the summer of 2015...

Little is currently known regarding competitor influence on pacing at the start of an event and in particular the subsequent effect on the remaining distance. The purpose of the present study was to investigate the influence of starting pace on the physiological and psychological responses during cycling time trials (TT) utilizing an innovative approach allowing pace to be accurately and dynamically replicated, as well as deceptively manipulated. Ten competitive male cyclists completed five 16.1 km TT, two baseline trials performed alone (BLs), and three with a simulated, dynamic avatar of which they were to match the pace of for the initial 4 km...

The interactions between the brain and the immune system are bidirectional. Nevertheless, we have far greater understanding of how the immune system affects the brain than how the brain affects immunity. New technological developments such as optogenetics and chemogenetics (using DREADDs; Designer Receptors Exclusively Activated by Designer Drugs) can bridge this gap in our understanding, as they enable an unprecedented mechanistic and systemic analysis of the communication between the brain and the immune system...

The visible burrow system produces a distinct combination of psychological and metabolic stress on, primarily, subordinate individuals that results in pronounced physiologic and behavioral dysfunction. However, the mechanisms underlying the consequences of chronic subordination stress are largely unknown. The simplest mechanistic explanation is that adaptations within brain systems with overlapping functions of both psychological and metabolic control provide immediate benefits that result in lasting susceptibility to diseases, disorders, and increased mortality rates in subordinates...

Rates of breastfeeding uptake are lower after a caesarean birth than vaginal birth, despite caesarean rates increasing globally over the past 30 years, and many high-income countries reporting overall caesarean rates of above 25%. A number of factors are likely to be associated with women's infant feeding decisions following a caesarean birth such as limited postoperative mobility, postoperative pain, and ongoing management of medical complications that may have triggered the need for a caesarean birth. The aim of this systematic review was to evaluate evidence of interventions on the initiation and duration of any and exclusive breastfeeding among women who had a planned or unplanned caesarean birth...

BACKGROUND: Tinnitus is the perception of sound without external acoustic stimuli. Patients with severe tinnitus may have physical and psychological complaints and their tinnitus can cause deterioration in their quality of life. At present no specific therapy for tinnitus has been found to be satisfactory in all patients. In recent decades, a number of reports have suggested that oral zinc supplementation may be effective in the management of tinnitus. Since zinc has a role in cochlear physiology and in the synapses of the auditory system, there is a plausible mechanism of action for this treatment...

Scholars have accumulated an abundant amount of knowledge on the association between work stressors and employees' health and well-being. However, notions of the complex interplay of physiological and psychological components of stress reactions are still in their infancy. Building on the Allostatic Load (AL) model, the present study considers short-term within-person effects of negative work events (NWEs) on indicators of both physiological (i.e., salivary cortisol) and psychological distress responses (i...

This paper investigates how social influence can alter physiological, psychological, and functional responses to a placebo product and how such responses influence the ultimate endorsement of the product. Participants consumed a product, "AquaCharge Energy Water," falsely-labeled as containing 200 mg of caffeine but which was actually plain spring water, in one of three conditions: a no social influence condition, a disconfirming social influence condition, and a confirming social influence condition. Results demonstrated that the effect of the product labeling on physiological alertness (systolic blood pressure), psychological alertness (self-reported alertness), functional alertness (cognitive interference), and product endorsement was moderated by social influence: participants experienced more subjective, physiological and functional alertness and stronger product endorsement when they consumed the product in the confirming social influence condition than when they consumed the product in the disconfirming social influence condition...

Context • The coexistence of affective disorders, especially anxiety and depression, with medical illness is a topic of considerable clinical and research interest. Complementary biofield modalities are therapies that involve touch or placement of the hands in or through biofields. Spiritual healing, or Spiritist passe (SP), is a kind of laying on of hands (LOH), and therefore is a biofield therapy. Objective • The current study intended to evaluate the effects of SP on psychological parameters such as anxiety and depression and on the perceptions of muscle tension and wellness as well as physiological parameters, such as pain intensity, heart rate (HR), and oxygen saturation (SpO2)...

Glucocorticoid hormones (cortisol and corticosterone - CORT) are the effector hormones of the hypothalamic-pituitary-adrenal (HPA) axis neuroendocrine system. CORT is a systemic intercellular signal whose level predictably varies with time of day and dynamically increases with environmental and psychological stressors. This hormonal signal is utilized by virtually every cell and physiological system of the body to optimize performance according to circadian, environmental and physiological demands. Disturbances in normal HPA axis activity profiles are associated with a wide variety of physiological and mental health disorders...
