#1
Margaretha Viljoen, Nicolaas Claassen
BACKGROUND: Cynicism, as a personality trait, has adverse effects on health. The question was asked whether cynical attitudes that develop due to work-related stress correlate with stress levels and whether it has a negative influence on health. OBJECTIVES: To investigate associations of the cynicism subscale scores of the Maslach Burnout Inventory-General Survey (MBI-GS) with levels of stress, anxiety, questionnaire-based physical health and with a number of physiological health risk indicators...

REVIEW
P Sgrò, L Di Luigi
The relationships between sport and sexuality in males are of great social and clinical interest, because of sports and motor activities that highly promote social and sexual relationships. Even if few literature exist, two main questions should be taken into account: whether and how physical exercise and sport positively or negatively influence sexual health and behavior and/or whether and how sexual behavior may affect a sub-sequent sport performance. Physical exercise and sport per se can influence, positively or negatively, the hypothalamic-pituitary-testicular axis function and, consequently, the individual's reproductive and/or sexual health...

INTRODUCTION: Early life stress (ELS) has been shown to play a role in establishing persistent maladaptive HPA axis modifications that may contribute to the pathogenesis of mood and anxiety disorders. Central glucocorticoid receptor (GR) messenger RNA (mRNA) expression may facilitate (mal)adaptive responsivity to ELS. The role of adult monocytic GR mRNA expression, a putative CNS proxy, during acute stress exposure was explored as well as the ELS marker, juvenile cerebrospinal fluid (CSF) corticotropin-releasing factor...

Laboratory animals experience a large amount of environmental stress. An animal's environment can include both physiological and social stressors that may require an animal to adapt to maintain allostatic balance. For example, thermal stress can lead to changes in behavior, reproduction and immune function, which has been detrimental to cancer modeling in mice. Chronic uncontrollable stress is widely acknowledged for its negative alterations to physiology. However, there is a lack in the understanding of how the laboratory environment affects animal physiology and behavior, particularly as it relates to characteristics of the human disease being modeled...

Social species in captivity may face allostatic overload due to artificial grouping and other social constraints. In rescue centres, groups of psittacines are constantly mixed due to the arrival and/or release of individuals; this procedure is potentially harmful to animal welfare. This study aimed at evaluating the possible impacts of mate replacement on the stress levels of captive blue-fronted amazon parrots (Amazona aestiva). During five weeks, we recorded agonistic interactions and dropping-glucocorticoid metabolites (GCM) concentrations of individuals allocated in a group whose members were kept constant and in a group subjected to frequent member replacement...

Background Excessive gambling is considered to be a part of the addiction spectrum. Stress-like emotional states are a key feature both of pathological gambling (PG) and of substance addiction. In substance addiction, stress symptomatology has been attributed in part to "anti-reward" allostatic neuroadaptations, while a potential involvement of anti-reward processes in the course of PG has not yet been investigated. Methods To that end, individuals with PG (n = 22) and mentally healthy subjects (n = 13) were assessed for trauma exposure and post-traumatic stress symptomatology (PTSS) using the Life Events Checklist and the Civilian Mississippi Scale, respectively...

Acute ethanol activates the hypothalamic-pituitary-adrenal (HPA) axis, while long-term exposure results in a blunted neuroendocrine state, particularly with regards to the primary endpoint, cortisol, the primary glucocorticoid produced in the adrenal cortex. However, it is unknown if this dampened neuroendocrine status also influences other adrenocortical steroids. Plasma concentration of the mineralocorticoid and neuroactive steroid precursor deoxycorticosterone (DOC) is altered by pharmacological challenges of the HPA axis in cynomolgus monkeys...

Understanding brain energy metabolism-neuroenergetics-is becoming increasingly important as it can be identified repeatedly as the source of neurological perturbations. Within the scientific community we are seeing a shift in paradigms from the traditional neurocentric view to that of a more dynamic, integrated one where astrocytes are no longer considered as being just supportive, and activated microglia have a profound influence. Lactate is emerging as the "good guy," contrasting its classical "bad guy" position in the now superseded medical literature...

Allostatic load (AL) is a complex clinical construct, providing a unique window into the cumulative impact of stress. However, due to its inherent complexity, AL presents two major measurement challenges to conventional statistical modeling (the field's dominant methodology): it is comprised of a complex causal network of bioallostatic systems, represented by an even larger set of dynamic biomarkers; and, it is situated within a web of antecedent socioecological systems, linking AL to differences in health outcomes and disparities...

OBJECTIVE: Developmental models of temperament by environment interactions predict that children's negative emotionality exacerbates the detrimental effects of risky environments, increasing the risk for pathology. However, negative emotions may have an adaptive function. Accordingly, the present study explores an alternative hypothesis that in the context of high adversity, negative emotionality may be a manifestation of an adaptive coping style and thus be protective against the harmful effects of a stressful environment...

Alcoholism is a complex brain disease characterized by three distinct stages of the addiction cycle that manifest as neuroadaptive changes in the brain. One such stage of the addiction cycle is alcohol withdrawal and the negative affective states that promote drinking and maintain addiction. Repeated alcohol use, genetic predisposition to alcoholism and anxiety, and alcohol exposure during crucial developmental periods all contribute to the development of alcohol-induced withdrawal and negative affective symptoms...

This article addresses the scope of the problem primary care physicians face when caring for the underserved, both nationally and internationally. It touches on the statistics used to define medically underserved communities, the pervasiveness of poverty, and how primary care physician shortages may soon reach a crisis point. The definitions of socioeconomic status, allostatic load, and structural violence are also reviewed.

Physical frailty in older people is an escalating health and social challenge. We investigate its physical, psychological, and social predictors, including how and for whom these conditions exert their effects. For 4638 respondents aged 65-89 years from wave 2 of the English Longitudinal Study of Ageing, we examine prediction of future physical frailty by physical, psychological, and social conditions using latent growth curve analysis with multiple indicators. In addition, we explore their indirect effects through disease and physiologic decline, and repeat these analyses after stratification by gender, age group, and selected conditions which are possible moderators...

BACKGROUND & OBJECTIVES: Allostatic load (AL) is a cumulative measure of physiological deregulation and is influenced by multiple factors including nutrition. The objectives of the study were to assess AL among adolescent boys (15-19 yr) and delineate its association with psychological stress and micronutrient status. METHODS: A cross-sectional, school-based study was conducted among 370 adolescent boys of five higher secondary schools from Hyderabad, India. Perceived stress, adolescent life event stress (ALES), psychological morbidity and coping were measured...

Background Allostatic load (AL) is an index of multi-system physiological "wear-and-tear," operationalizing emergent chronic disease risk and predicting morbidity and mortality. AL has been proposed as an organizing framework for studying pregnancy outcomes and additional AL biomarkers for the study of maternal health would be valuable. Objectives To test whether adverse perinatal outcomes are associated with postpartum AL and if including vitamin D deficiency (serum 25(OH)D < 20 ng/ml) as an additional marker of postpartum AL increases the association...

The prefrontal cortex (PFC) represents and executes the highest forms of goal-directed behavior, and has thereby attained a central neuroanatomical position in most pathophysiological conceptualizations of motivational disorders, including alcohol use disorder (AUD). Excessive, intermittent exposure to alcohol produces an allostatic dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis along with heightened forebrain glucocorticoid signaling that can damage PFC architecture and function. Negative affective states intimately associated with the transition to alcohol dependence result not only from a dysregulated HPA axis, but also from the inability of a damaged PFC to regulate subcortical stress and reinforcement centers, including the ventral striatum and amygdala...

Lead levels (Pb) have been linked to both hyper- and hypo-reactivity of hypothalamic-pituitary-adrenal axis (HPA) axis to acute stress in animals and humans. Similarly, allostatic load (AL), the 'wear and tear' of chronic stress, is associated with inadequate HPA axis activity. We examined whether Pb levels would be associated with altered diurnal cortisol profile, as a primary mediator of AL, during aging. Pb levels were measured from blood samples (BPb) of 126 Brazilian individuals (105 women), between 50 and 82 years old...

Multiple stressors affect developing and adult organisms, thereby partly structuring their phenotypes. Determining how stressors influence health, well-being, and longevity in human and nonhuman primate populations are major foci within biological anthropology. Although much effort has been devoted to examining responses to multiple environmental and sociocultural stressors, no holistic metric to measure stress-related physiological dysfunction has been widely applied within biological anthropology. Researchers from disciplines outside anthropology are using allostatic load indices (ALIs) to estimate such dysregulation and examine life-long outcomes of stressor exposures, including morbidity and mortality...

Using a rat model of chronic sleep restriction (CSR) featuring periodic sleep deprivation with slowly rotating wheels (3h on/1h off), we previously observed that 99h of this protocol induced both homeostatic and allostatic (adaptive) changes in physiological and behavioural measures. Notably, the initial changes in sleep intensity and attention performance gradually adapted during CSR despite accumulating sleep loss. To identify brain regions involved in these responses, we used FosB/ΔFosB immunohistochemistry as a marker of chronic neuronal activation...
