Salivary markers of aggression - The possible alterations in salivary hormones levels to identify perpetrators of aggression-related violence. Leg Med (Tokyo) 2024; 71:102501. [PMID: 39083886 DOI: 10.1016/j.legalmed.2024.102501] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2024] [Revised: 07/13/2024] [Accepted: 07/24/2024] [Indexed: 08/02/2024]
Abstract
Aggression, understood as intentional actions aimed at causing harm, remains in a direct relation with the phenomenon of interpersonal violence, especially its physical form. Creating an objective marker of aggression would be an important tool for preventing, protecting the victims and maintaining control over suspects. There have been attempts to link aggression with shifts in hormone levels, including those that can be measured in saliva, especially testosterone and cortisol. The systematic review aimed to assess changes in salivary hormone levels among perpetrators of violence, with particular emphasis on physical violence, as parameters pointing to perpetrators of violence. Following the inclusion and exclusion criteria, 22 studies were included. Most of the papers included in the analysis came from the USA and Europe. Studies typically included adults as well as children, while focusing mainly on men. Among the hormones, salivary testosterone levels were the ones analyzed most frequently. On the basis of the included studies, a meta-analysis was conducted on the relationship between aggressive behavior and the levels of concentration of testosterone and cortisol measured in saliva. Regardless of gender, individuals exhibiting aggressive behavior were proved to have significantly higher testosterone levels and lower cortisol concentrations in saliva measurements. The obtained results indicate the feasibility of using the examined parameters for initial detection of perpetrators of aggression-related violence. However, further research is necessary to more precisely determine the relationship between aggressive behavior and hormonal changes in order to determine the feasibility of using these parameters as an objective marker for early identification of perpetrators.

Abstract
All humans deal with acute psychological stress periodically. Some individuals are affected by needle phobia in which a heightened sense of arousal is precipitated by venepuncture. Acute psychological stress invokes a range of physiological changes including activation of the sympathetic-adrenal-medullary and hypothalamic-pituitary-adrenal axes. In this review article, we first examine the human response to acute stress. We then provide an overview of how psychological stress in a subject is likely to be a source of pre-analytical variability for certain measurands, and the major biochemical markers that have been studied in research aiming to quantify stress. As such, we highlight how stress can be a hindrance to the accurate interpretation of certain laboratory results (particularly cortisol, prolactin, metanephrines and growth hormone), and point out the role that biochemical analysis might play in future studies looking at the effects of stress on human behaviour.

Abstract
PURPOSE Noise has become an integral part of human life. Noise stress affect various physiological indices. In the present study, the effects of acute noise stress on corticosterone and testosterone and testosterone to cortisol ratio (T/C) in male rats, trained with two types of high-intensity interval training (HIIT) and moderate-intensity continuous training (MCT) were evaluated. METHODS 42 male Wistar rats were divided randomly into seven groups, including the control group (C), control time (CT), exposure to acute noise stress (S), HIIT, MCT, HIIT with noise stress (HIIT + S), and MCT with noise stress (MCT + S). Exercise groups performed eight weeks of exercise training. One session of stress was induced in stress groups following the intervention (exercise or rest) period. Serum levels of corticosterone and T/C were measured through blood samples, taken 48 hours following the last session of exercise in the four exercise groups without noise stress and time control. Immediately after noise stress, blood samples were taken in 3 stress groups. RESULTS Serum level of corticosterone in the MCT group was significantly higher than CT and HIIT groups (P = 0.001). Considering the effect of acute noise stress, corticosterone was significantly higher in HIIT + S and MCT + S, respectively, compared to the noise stress group (P < 0.001). Testosterone level of the noise stress group was significantly lower than CT group (P < 0.001). Testosterone level in the S group was significantly lower than other stress groups (MCT + S and HIIT + S) (P < 0.001). T/C in HIIT + S group was significantly higher compared to S and MCT + S groups (P < 0.001). CONCLUSION HIIT and MCT, by priority, ameliorated the deteriorating effect of noise stress on testosterone and T/C; and it appears that the intensity and mode of previous exercise training affect the hormonal response to noise stress.

Hormonal Profile in Response to an Empathic Induction Task in Perpetrators of Intimate Partner Violence: Oxytocin/Testosterone Ratio and Social Cognition. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:7897. [PMID: 35805556 PMCID: PMC9265590 DOI: 10.3390/ijerph19137897] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Revised: 06/23/2022] [Accepted: 06/24/2022] [Indexed: 02/05/2023]
Abstract
Empathy deficits have been proposed to be an important factor for intimate partner violence (IPV). IPV perpetrators have shown a differential change in salivary oxytocin (sOXT), testosterone (sT), and cortisol (sC), following empathic and stress tasks, compared to non-violent men. However, the influence of empathic deficits in those hormones after an emotion-induction task in IPV perpetrators remains unclear. We analyzed the effects of an empathic induction task on endogenous sOXT, sT and sC levels, as well as their hormonal ratios, in IPV perpetrators (n = 12), and compared them to controls (n = 12). Additionally, we explored the predictive capacity of empathy-related functions (measured with the interpersonal reactivity index) in the hormonal responses to the task. IPV perpetrators presented lower sOXT changes and higher total sT levels than controls after the task, lower sOXT/T change and total sOXT/T levels, as well as higher total sT/C levels. Notably, for all participants, the lower the perspective taking score, the lower the total sOXT levels and sOXT changes and the higher the sT changes were. Low perspective taking also predicted smaller sOXT/T and sOXT/C changes in the empathic induction task, and higher total sT/C levels for all participants. Therefore, our results could contribute to furthering our ability to focus on new therapeutic targets, increasing the effectiveness of intervention programs and helping to reduce IPV recidivism in the medium term.

Abstract
The use of saliva as a biological sample has many advantages, being especially relevant in pigs where the blood collection is highly stressful and painful, both for the animal and the staff in charge of the sampling. Currently one of the main uses of saliva is for diagnosis and detection of infectious diseases, but the saliva can also be used to measure biomarkers that can provide information of stress, inflammation, immune response and redox homeostasis. This review will be focused on the analytes that can be used for such evaluations. Emphasis will be given in providing data of practical use about their physiological basis, how they can be measured, and their interpretation. In addition, some general rules regarding sampling and saliva storage are provided and the concept of sialochemistry will be addressed. There is still a need for more data and knowledge for most of these biomarkers to optimize their use, application, and interpretation. However, this review provides updated data to illustrate that besides the detection of pathogens in saliva, additional interesting applicative information regarding pigs´ welfare and health can be obtained from this fluid. Information that can potentially be applied to other animal species as well as to humans.

Abstract
OBJECTIVE To analyze the available data on the anti-anger effects of herbal medicines (HMs) as well as their underlying mechanisms in rat models. METHODS From 6 electronic databases [PubMed, EMBASE, China National Knowledge Infrastructure (CNKI), Wanfang, Oriental Medicine Advanced Searching Integrated System (OASIS), and Research Information Sharing Service (RISS)], relevant animal experiments were searched by using "anger," "rats," and "animal" as search keywords. The last search was conducted on November 22, 2019, and all experiments involving rat models of anger and treatment using HMs published until the date of the search were considered. RESULTS A total of 24 studies with 16 kinds of HMs were included. Most studies have used the "tail irritating method" and "social isolation and resident intruder" method to establish anger models. According to the included studies, the therapeutic mechanisms of HMs for anger regulation and important herbs by their frequency and/or preclinical evidence mainly incladed regulation of hemorheology (Bupleuri Radix, Paeoniae Radix Alba, and Glycyrrhizae Radix), regulation of sex hormones (Bupleuri Radix, Cyperi Rhizoma, and Paeoniae Radix Alba), regulation of neurotransmitters (Cyperi Rhizoma), regulation of anger-related genes (Bupleuri Radix, Glycyrrhizae Radix, and Paeoniae Radix Alba), and other effects. Overall, Liver (Gan) qi-smoothing herbs including Bupleuri Radix and Cyperi Rhizoma were the most frequently used. CONCLUSIONS This review found the frequent methods to establish an anger model, and major mechanisms of anti-anger effects of HMs. Interestingly, some Liver qi-smoothing herbs have been frequently used to investigate the anti-anger effects of HM. These findings provide insight into the role and relevance of HMs in the field of anger management.

Oxytocin moderates the association between testosterone-cortisol ratio and trustworthiness: A randomized placebo-controlled study. COMPREHENSIVE PSYCHONEUROENDOCRINOLOGY 2021; 8:100080. [PMID: 35757666 PMCID: PMC9216378 DOI: 10.1016/j.cpnec.2021.100080] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2021] [Revised: 08/11/2021] [Accepted: 08/11/2021] [Indexed: 11/09/2022] Open
Abstract
Oxytocin has been proposed to enhance feelings of trust, however, these findings have been difficult to replicate. Environmental or hormonal factors might influence this association. We studied whether oxytocin moderates the association between the testosterone-cortisol ratio, which is associated with risk taking behavior and aggression, and trustworthiness, while controlling for the general level of trust. A randomized double-blind placebo-controlled study with 53 healthy males was performed in which 32IU oxytocin (n = 27) or placebo (n = 26) was administered intranasally. Participants subsequently played the Trust Game in which they were allocated to the role of trustee. In the third phase of the Trust Game, we found a positive association between the testosterone-cortisol-ratio and the proportion of the amount that is returned to the investor (P=<0.01). However, administration of oxytocin reduced reciprocity in those with a high testosterone-cortisol ratio after reciprocity restoration (a significant interaction effect between administration of oxytocin and the testosterone-cortisol ratio in the third phase of the Trust Game, P = 0.015). The third phase of the Trust Game represents the restoration of reciprocity and trustworthiness, after this is violated in the second phase. Therefore, our data suggest that oxytocin might hinder the restoration of trustworthiness and diminish risk-taking behavior when trust is violated, especially in those who are hormonally prone to risk-taking behavior by a high testosterone-cortisol ratio. Oxytocin (32IU) was administered intranasally to healthy young males in a double-blind placebo-controlled study. Testosterone-cortisol ratio was positively associated with trustworthiness during the Trust Game. Oxytocin significantly attenuated the association between testosterone-cortisol ratio and trustworthiness.

Abstract
The quantification of steroid hormones of individual zebrafish (Danio rerio) provides perspective to understand endogenous hormone function. A UPLC–TOF–MS method was developed to provide a reproducible, sensitive, and efficient assay to determine the concentration of steroid hormones, including cortisol, testosterone, androstenedione, 11-deoxycortisol, 11-deoxycorticosterone, and 17-hydroxyprogesterone in whole-body homogenates of each zebrafish. Solid-phase extraction was used to sample matrix clean-up and acquired a recovery from 89.7% to 107.9%. The analytes were separated on an Aquity BEH C18 column using gradient elution. Mass spectrometric analysis was performed by single reaction monitoring (SRM) using positive electrospray ionization mode. The total running time was 6 min, which was greatly shortened compared with a previously reported method. The developed method exhibited excellent linearity for all the analytes, with regression coefficients higher than 0.99. The limit of detection varied between 0.1 and 0.5 ng/L and the limit of quantification was 0.5–1.7 ng/L for all analytes. The precision of the method was assessed on replicate measurements and was found to be in the ranges of 1.9 % to 6.6% and 4.3% to 8.6%, for intra- and inter-day analysis, respectively. This method was validated according to FDA guidance and applied to determine steroid hormone levels in the tissue homogenate of zebrafish acutely treated with caffeine and ethanol.

Stress responses in high-fidelity simulation among anesthesiology students. Sci Rep 2021; 11:17073.

Abstract
Simulation sessions can produce high-fidelity emergency situations that facilitate the learning process. These sessions may also generate a complex stress response in the learners. This prospective observational study assessed psychological, physiological, immunological, and humoral levels of stress during high-fidelity simulation training. Fifty-six undergraduate medicine students who took part in a medical simulation session were assigned team roles (physician, nurse or assistant). Subsequently, each participant was assessed before the scenario (T0), after the procedure (T1), and two hours later (T2). Psychological stress and anxiety were measured at T0 and T1, using the State-Trait Anxiety Inventory (STAI) and Dundee Stress State Questionnaire (DSSQ). Cortisol, testosterone, secretory immunoglobulin class A (sIgA), alpha-amylase, and oxygen saturation level were measured at T0, T1, and T2, as was the physiological response indicated by heart rate (HR) and blood pressure (BP). It was found that the onset of task performance was related to increased anticipatory worry and higher oxygen saturation. The participants reported decreased worry, followed by increased emotional distress after the simulation training (T1). Participants trait anxiety predicted the intensity of worry, distress and task engagement. In contrast, no clear relationships were found between trait anxiety and biological stress markers. Testosterone levels were growing significantly in each phase of measurement, while physiological responses (BP, HR) increased at T1 and declined at T2. The levels of stress markers varied depending on the assigned roles; however, the trajectories of responses were similar among all team members. No evidence for prolonged cortisol response (T1, T2) was found based on psychological stress at the onset of simulation (T0). Regression analysis followed by receiver operating characteristics analyses showed uncertain evidence that initial state anxiety and worry predicted the levels of sIgA. Medical students are relatively resilient in terms of stress responses to medical simulation. The observed stress patterns and interrelationships between its psychological, physiological, hormonal, and immunological markers are discussed in accordance with theoretical concepts, previous research work, and further recommendations.

Abstract
BACKGROUND Only a few studies have paid attention to the ability of perpetrators of intimate partner violence (IPVAW) against women to cope with acute stress, including hormonal parameters. In fact, previous studies assessed how salivary testosterone (Tsal) and cortisol (Csal) changed after coping with an acute emotional stressor (directly related to IPVAW), and they concluded that an imbalance between the two hormones might be characteristic of these men. Nevertheless, they neglected to examine the role of other hormones, such as salivary oxytocin (OXsal), which also seemed to play an important role in behavioral regulation, and whether this response could be generalized to other types of stress not directly related to IPVAW. METHODS This study aims to assess whether IPVAW perpetrators (n = 19) present differential hormonal (Tsal, Csal, OXsal and their ratios) and psychological state (anxiety, anger, and general affect) responses when coping with an acute cognitive laboratory stressor (a set of neuropsychological tests performed in front of an expert committee) in comparison with non-violent men (n = 16). This quasi-experimental study also assessed whether the psychological state variables drive this different hormonal response. RESULTS Our results revealed that IPVAW perpetrators had lower Csal and higher Tsal/Csal ratio levels during the post-task period, as well as higher total levels (average) of OXsal than controls. We also found that, only in IPVAW perpetrators, high levels of baseline anxiety and negative affect were related to high rises in Csal during the stress task. CONCLUSIONS These data present a background showing that IPVAW perpetrators and non-violent men cope differently with stress. These findings might help to identify idiosyncratic profiles of IPVAW perpetrators that can then be employed to establish their therapeutic needs. Moreover, we reinforced the importance of combining biological markers with self-reports, thus increasing the reliability of these forensic assessments.

Abstract
The factors influencing Leydig cell maturity and the acquisition of functional capacity are incompletely defined. Here we analyzed the constant light (LL) influence on Leydig cells' endocrine function during reproductive maturation. Rats were exposed to LL from P21 to P90. Data were collected at juvenile (P35), peri/pubertal (P42, P49), and adult (P90) stages of life. The results proved the effect of LL on rats' physiology by changing of bimodal voluntary activity pattern into free-running. Additionally, the peripheral clock in Leydig cells changed in LL condition, indicating disturbed rhythm: the positive element (Bmal1) increased in pre-/pubertal but decreased in the adult period, while negative elements (Per2 and Reverba) were increased. The effects of LL were most prominent in puberty: pituitary genes encoding gonadotropic hormones (Cga, Lhb, Fshb) decreased; serum corticosterone increased, while serum androgens and mass of testicular and sex accessory organs reduced; markers of Leydig cells maturity/differentiation (Insl3, Lhcgr) and steroidogenesis-related genes (Scarb1, Star, Cyp11a1, Cyp17a1) decreased; the steroidogenic and energetic capacity of the Leydig cell mitochondria decreased; the mtDNA copy number reduced, and mitochondrial dynamics markers changed: fusion decreased (Opa1 and Mfn2), and mitophagy increased (Pink1). In adults, the negative effect of LL on mitochondrial function and steroidogenic capacity persists in adult Leydig cells while other parameters reached control values. Altogether, the results indicate that LL slows down Leydig cells' maturation by reducing the endocrine and energy capacity of cells leading to the delay of reproductive development.

Abstract
In contrast to the large body of research on the effects of stress-induced cortisol on memory consolidation in young people, far less attention has been devoted to understanding the effects of stress-induced testosterone on this memory phase. This study examined the psychobiological (i.e., anxiety, cortisol, and testosterone) response to the Maastricht Acute Stress Test and its impact on free recall and recognition for emotional and neutral material. Thirty-seven healthy young men and women were exposed to a stress (MAST) or control task post-encoding, and 24 h later, they had to recall the material previously learned. Results indicated that the MAST increased anxiety and cortisol levels, but it did not significantly change the testosterone levels. Post-encoding MAST did not affect memory consolidation for emotional and neutral pictures. Interestingly, however, cortisol reactivity was negatively related to free recall for negative low-arousal pictures, whereas testosterone reactivity was positively related to free recall for negative-high arousal and total pictures. This study provides preliminary evidence about a different reactivity of testosterone and cortisol to the MAST as well as on their effects on consolidation. Our results suggest a different pattern of relationships between these steroid hormones and the arousal of the negative images.

Abstract
Recent studies have highlighted the dysregulation of hypothalamic-pituitary-adrenal (HPA) axis activity and its end products, cortisol and dehydroepiandrosterone (DHEA), in women with a history of intimate partner violence (IPV) victimization. These studies analyzed several coping styles, but they neglected to examine the use of violent strategies to confront IPV and the way these strategies affect HPA functioning. This latter proposal would be based on the gender symmetry model of IPV, which sustains that IPV is generally symmetrical, but that women's violence tends to be a reaction to male violence. Hence, the main objective of the present study was to examine whether women's violent reactions to IPV would significantly predict salivary cortisol and DHEA levels, as well as the cortisol/DHEA ratio (assessed through two saliva samples per day on four consecutive work days), controlling for the women's prior IPV abuse, psychopathology, and demographic variables. Our data demonstrated that, specifically, psychological confrontation strategies predicted vespertine cortisol levels (adj R2 = .18, β = .447, p < .01) and the cortisol/DHEA ratio (adj R2 = .08, β = .322, p < .05), even after controlling several confounding variables, whereas physical and total confrontation in response to IPV did not predict these hormonal parameters.

Abstract
Psychogenic non-epileptic seizures (PNES) is a conversion disorder that reflects underlying psychological distress. Female patients with PNES often present with a history of prolonged stressors, especially sexual abuse. In the current study, we studied the relationship between neuropeptide Y (NPY) and PNES symptoms in women with a history of sexual abuse. NPY has been associated with resilience to stress and we hypothesized that low levels would increase the extent and severity of PNES symptoms in this patient population. Serum levels of NPY, and related hormones were measured in fifteen female PNES patients and sixty female controls. PNES patients reported more severe abuse histories, feeling of abandonment, and decreased perception of quality of life than controls. Importantly, they also had lower NPY levels. Our analysis indicates that low levels of NPY in PNES may confer greater vulnerability to exhibit seizure-like symptoms and lower quality of life.

Abstract
Competition and cooperation are two somewhat opposed strategies for interpersonal social interaction that help us to achieve both individual and shared goals. The main aim of this study was to explore which type of social interaction (cooperative or competitive) is more stressful in a face-to-face same-sex dyad in healthy young participants (n = 178), considering outcome obtained in these tasks (positive or negative) and sex as moderating variables, and performance of the task alone as a control condition. Salivary cortisol (Csal) was measured in one sample obtained before task and four obtained after the task (+0, +15, +30 and +45 minutes after). Anxiety-state was assessed before and immediately after the task. Participants who cooperated and obtained negative outcomes had higher Csal levels than those who worked alone with negative outcomes in all periods after the task (p = .008, η p 2 = .058 and p = .033, η p 2 = .031, respectively). Moreover, those who cooperated showed higher mean self-reported state anxiety levels than the rest of the participants (p = .013, η p 2 = .051 and p < .001, η p 2 = .530, respectively). Our study indicates that cooperation between strangers in face-to-face dyads is highly stressful, more so than competing or working alone. These results should be taken into account for understanding situations of social stress and can be generalized to situations in which subjects cooperate or must decide between cooperating and competing to attain a goal.

Abstract
The present study aimed to extend the original focus of the dual-hormone hypothesis on testosterone and cortisol involvement in risk-taking to other sex hormones: estrogen and progesterone. The study also examined two alternative models for the proposed relationship between cortisol and sex steroids and for their joint influence on risk-taking: interaction and ratio terms. In all, 40 women and 37 men were tested for circulating sex hormones and provided self-reports on risk-taking. The findings suggest that sex hormone-cortisol ratios differentially modulate risk-taking in men and women: In men, high ratios were associated with risk-taking, whereas in women the opposite pattern was found. The findings are discussed in light of evolutionary assumptions regarding sex differences in neuroendocrine mechanisms, suggesting sex differences in neural sensitivity to sex hormones in risk-taking.

Abstract
Caring for an offspring diagnosed with a psychological chronic disorder is used in research as a model of chronic stress. Indeed, it is usually associated with disturbances in the salivary cortisol (Csal) levels of the caregiver. An imbalance between salivary testosterone (Tsal) and Csal levels is a marker of proneness to social aggression. Given this, we aimed to establish whether the salivary testosterone/cortisol (Tsal/Csal) ratio response to acute stress could be employed as a marker of proneness to anger in informal caregivers of offspring with autism spectrum (ASD). Tsal/Csal ratio and anger responses to a set of different cognitive tasks as well as anger trait and expression were compared in these informal caregivers and controls. Caregivers, particularly those of offspring with ASD, had higher Tsal/Csal ratios than controls in response to acute stress, concretely after the stress in the case of fathers (p = .05) and before stress when analyzing mothers (p = .05). Moreover, ASD fathers and mothers obtained higher magnitude of the T/C ratio response to stress (p = .03 and p =.04, respectively), anger state (p = .02 and p = .02, respectively) and expression scores (p = .05 and p = .05, respectively) than controls. Finally, high Tsal/Csal ratio levels and response to stress were significantly associated with high anger feelings increases (p .05, respectively) and expression (p .05, respectively) in caregivers.

Depressive Mood and Testosterone Related to Declarative Verbal Memory Decline in Middle-Aged Caregivers of Children with Eating Disorders.

Abstract
Caring for children diagnosed with a chronic psychological disorder such as an eating disorder (ED) can be used as a model of chronic stress. This kind of stress has been reported to have deleterious effects on caregivers’ cognition, particularly in verbal declarative memory of women caregivers. Moreover, high depressive mood and variations in testosterone (T) levels moderate this cognitive decline. The purpose of this study was to characterize whether caregivers of individuals with EDs (n = 27) show declarative memory impairments compared to non-caregivers caregivers (n = 27), using for this purpose a standardized memory test (Rey’s Auditory Verbal Learning Test). Its purpose was also to examine the role of depressive mood and T in memory decline. Results showed that ED caregivers presented high depressive mood, which was associated to worse verbal memory performance, especially in the case of women. In addition, all caregivers showed high T levels. Nonetheless, only in the case of women caregivers did T show a curvilinear relationship with verbal memory performance, meaning that the increases of T were associated to the improvement in verbal memory performance, but only up to a certain point, as after such point T continued to increase and memory performance decreased. Thus, chronic stress due to caregiving was associated to disturbances in mood and T levels, which in turn was associated to verbal memory decline. These findings should be taken into account in the implementation of intervention programs for helping ED caregivers cope with caregiving situations and to prevent the risk of a pronounced verbal memory decline.

Abstract
It has been hypothesized that anger expression may be associated with increased salivary immunoglobulin A (sIgA) levels, which is associated with decreased somatic symptoms, and therefore anger expression may be associated with reduced somatic symptoms in intimate partner violence (IPV) perpetrators. This study tested the potential mediating effect of sIgA levels on the relationship between anger expression and respiratory and gastrointestinal symptoms in IPV perpetrators and non-violent controls. The sample consisted of IPV perpetrators (n = 19) and controls (n = 21). Saliva samples were collected for assessing sIgA levels. The State-Trait Anger Expression Inventory-2 was used to assess anger expression and the Revised version of the Somatic Symptoms Scale developed by Sandín and Chorot to measure somatic symptoms. High anger expression was associated with low levels of respiratory and gastrointestinal symptoms in IPV perpetrators mediated through high sIgA levels but the same was not true for non-violent controls. This finding supports the hypothesis that for IPV perpetrators, anger expression may be physiologically and psychologically rewarding. Future research examining other immunological parameters is needed to further test this hypothesis. Such effort may illuminate why some IPV perpetrators continue to use violence against their partners.

Abstract
Hormone ratios have become increasingly popular throughout the neuroendocrine literature since they offer a straightforward way to simultaneously analyze the effects of two interdependent hormones. However, the analysis of ratios is associated with statistical and interpretational concerns which have not been sufficiently considered in the context of endocrine research. The aim of this article, therefore, is to demonstrate and discuss these issues, and to suggest suitable ways to address them. In a first step, we use exemplary testosterone and cortisol data to illustrate that one major concern of ratios lies in their distribution and inherent asymmetry. As a consequence, results of parametric statistical analyses are affected by the ultimately arbitrary decision of which way around the ratio is computed (i.e., A/B or B/A). We suggest the use of non-parametric methods as well as the log-transformation of hormone ratios as appropriate methods to deal with these statistical problems. However, in a second step, we also discuss the complicated interpretation of ratios, and propose moderation analysis as an alternative and oftentimes more insightful approach to ratio analysis. In conclusion, we suggest that researchers carefully consider which statistical approach is best suited to investigate reciprocal hormone effects. With regard to the hormone ratio method, further research is needed to specify what exactly this index reflects on the biological level and in which cases it is a meaningful variable to analyze.

Abstract
Recently, cortisol has been suggested to moderate the positive relationship between testosterone and antisocial behavior. More precisely, high testosterone levels have been found to be related to aggressive or dominant behavior especially when cortisol levels were low. In the present study, we aimed to extend these findings to pro-environmental behavior as an indicator of prosocial behavior. In a first step, 147 male participants provided information on their everyday pro-environmental behavior by completing an online questionnaire on various energy-saving behaviors. In a second step, subjects provided two saliva samples for the assessment of testosterone and cortisol on two subsequent mornings after awakening. We found that testosterone was negatively related to pro-environmental behavior, but only in men with low cortisol. In conclusion, our findings provide first evidence for the joint association of testosterone and cortisol with everyday pro-environmental behavior. These results further reinforce the importance of considering interdependent hormone systems simultaneously rather than focusing on a single hormone.

Abstract
Testosterone and cortisol have been proposed to jointly regulate aggressive behavior. However, few empirical studies actually investigated this joint relation in humans, and reported inconsistent findings. Also, samples in these studies were small and/or specific, and consisted largely of males. Therefore, in the current study testosterone and cortisol in relation to aggression were investigated in a non-clinical sample of 259 boys and girls (mean age 16.98 years, SD = 0.42, 56% boys). A positive testosterone/cortisol ratio, that is, high testosterone relative to cortisol, was found to be associated with aggressive behavior, explaining 7% of the variance. The interaction between testosterone and cortisol was not related to aggressive behavior and gender differences were not found. The ratio may reflect an imbalance leaving the individual more prone to rewarding aspects, than fearful of negative implications of aggressive behavior. Current findings indicate that this relation can be generalized to aggression in non-clinical adolescents.

Abstract
This introduction sets out to present a series of paper about a novel perspective regarding stress and sex hormones, or what the authors within this special issue term "coupling" of hypothalamic-pituitary-adrenal and--gonadal axes. This view postulates that these axes do not necessarily operate in opposition, but can operate together as evidenced empirically as a positive within-person association between stress hormones like cortisol or sex hormones like testosterone. A wealth of papers within the special issue demonstrate positive coupling across acute, diurnal, basal, and longitudinal timeframes and across several different types of contexts. Reviews were meant to challenge whether this was physiologically plausible. Consistently, sophisticated statistical models were utilized in order to show a template for how to model positive coupling and to ensure that coupling was a within-person phenomenon. We cautiously considered positive coupling until the consistency of observing coupling was robust enough for us to consider challenging the prevailing oppositional view of these axes. We do so to acknowledge that there are contexts, moments and stages in which the function of these axes should work together: for example when contexts are both stressful and challenging or at developmental stages (like adolescence) in which the youth must grow up despite the storm and stress of youth. We hope that by putting forward a functional dual-axis approach, the field will be able to consider when and how these axes work together.

Behav Sci (Basel) 2015; 5:113-20.

Abstract
The imbalance between testosterone (T) and cortisol (C) levels has been proposed as a possible marker of risk for intimate partner violence (IPV). Moreover, it could be related to a high probability of adopting risky behaviors such as alcohol abuse which, in turn, promotes the onset of IPV. This study tested the potential mediating effect of alcohol consumption on the relationship between baseline T/C ratio and anger expression in IPV perpetrators and non-violent controls. Alcohol consumption was higher in the former than controls. A high baseline T/C ratio was only associated with high anger expression in IPV perpetrators, and this association was mediated by high alcohol consumption. Thus, alcohol abuse may act as a catalytic factor in this relationship, high consumption promoting the onset of IPV. These findings contribute to the development of effective treatment and prevention programs, which could introduce the use of biological markers for preventing the onset, development and recidivism of IPV.

Abstract
Adversity early in life can disrupt the functioning of the hypothalamic-pituitary-adrenal and hypothalamic-pituitary-gonadal axes and increase risk for negative health outcomes. The interplay between these axes and the environment is complex, and understanding needs to be advanced by the investigation of the multiple hormonal relationships underlying these processes. The current study examined basal hormonal associations between morning levels of cortisol, testosterone, and dehydroepiandrosterone in a cohort of adolescents (mean age 15.56 years). The moderating influence of childhood adversity was also examined, as indexed by self-reported trauma (at mean age 14.91), and observed maternal aggressive parenting (at mean age 12.41). Between-person regressions revealed significant associations between hormones that were moderated by both measures of adversity. In females, all hormones positively covaried, but also interacted with adversity, such that positive covariation was typically only present when levels of trauma and/or aggressive parenting were low. In males, hormonal associations and interactions were less evident; however, interactions were detected for cortisol-testosterone - positively covarying at high levels of aggressive parenting but negatively covarying at low levels - and DHEA-cortisol - similarly positively covarying at high levels of parental aggression. These results demonstrate associations between adrenal and gonadal hormones and the moderating role of adversity, which is likely driven by feedback mechanisms, or cross-talk, between the axes. These findings suggest that hormonal changes may be the pathway through which early life adversity alters physiology and increases health risks, but does so differentially in the sexes; however further study is necessary to establish causation.

Abstract
This study examined whether physical intimate partner violence (IPV) victimization was associated with diurnal patterns of salivary cortisol in a community sample of 122 couples in their 30s from predominantly lower socioeconomic status backgrounds. Findings indicate that women with higher levels of victimization exhibited flatter patterns of diurnal cortisol characterized by both higher midday levels and more attenuated decreases in cortisol levels across the day, compared to women with lower levels of victimization. However, men's victimization was not associated with their diurnal cortisol levels. This study advances our understanding of the association between physical IPV victimization and dysregulated hypothalamic-pituitary-adrenal (HPA) axis functioning in women, which is likely to have further implications for their subsequent mental and physical health.

Abstract
Intimate partner violence (IPV) perpetrators have been categorized into two groups based on their heart rate (HR) reactivity to stress following Gottman's studies. Overall, type I perpetrators tend to show autonomic underarousal, whereas type II or reactive perpetrators present a hyper-reactivity in anticipation of stress. In this study, changes in HR, pre-ejection period (PEP), vagal ratio as well as psychological state variables (anxiety and anger) in response to stress were assessed, comparing a group of type II IPV perpetrators (based on violence reports and psychological assessment; n = 17; mean age = 37) with non-violent controls (n = 17; mean age = 35) using modified version of the Trier Social Stress Test. IPV perpetrators had higher HRs and lower vagal ratios than controls, particularly during the recovery period. Moreover, the former presented shorter PEPs than controls. There were no differences between groups in the magnitude of response of the HR, PEP or vagal ratio. High baseline anxiety and anger were associated with an HR increase during the preparation time in IPV perpetrators but not in controls. These findings indicate a different cardiovascular pattern of response to psychosocial stress in IPV perpetrators, especially during recovery. Thus, they contribute to understanding the biological functioning of violence sub-types, supporting the validity of cardiovascular measures as diagnostic indicators for IPV classification.

Abstract
It has been suggested that being physically abused leads to someone becoming a perpetrator of abuse which could be associated to parents' gender, timing of the physical abuse and specific socio-demographic variables. This study aims to investigate the role the parents' gender, timing of childhood abuse and socio-demographic variables on the relationship between parents' history of childhood physical abuse and current risk for children. The sample consisted of 920 parents (414 fathers, 506 mothers) from the Portuguese National Representative Study of Psychosocial Context of Child Abuse and Neglect who completed the Childhood History Questionnaire and the Child Abuse Potential Inventory. The results showed that fathers had lower current potential risk of becoming physical abuse perpetrators with their children than mothers although they did not differed in their physical victimization history. Moreover, the risk was higher in parents (both genders) with continuous history of victimization than in parents without victimization. Prediction models showed that for fathers and mothers separately similar socio-demographic variables (family income, number of children at home, employment status and marital status) predicted the potential risk of becoming physical abuses perpetrators. Nevertheless, the timing of victimization was different for fathers (before 13 years old) and mothers (after 13 years old). Then our study targets specific variables (timing of physical abuse, parents' gender and specific socio-demographic variables), which may enable professionals to select groups of parents at greater need of participating in abuse prevention programs.

Abstract
In this report, salivary cortisol, alpha-amylase activity, and testosterone were measured to assess stress associated with a public oral presentation in Veterinary Clinical Pathology students. Stimulated saliva samples were collected before and directly after a 5-minute oral presentation and at 20 and 35 minutes after the beginning of the presentation. Cortisol peaked 20 minutes after the beginning of the presentation, whereas salivary alpha-amylase (sAA) peaked at 5 minutes, just at the end of the speech. These changes were not related to the level of stress that was indicated by the student in a questionnaire, the student's sex, or the quality of the presentation. No changes were detected in testosterone levels during the study. Saliva biomarkers evaluated in this research could be extended to other stress-producing situations in the university life of veterinary students.

Abstract
Hormonal and neuropsychological impairment in intimate partner violence (IPV) perpetrators could play a role in domestic violence. For characterizing whether there is a specific psychobiological response to stress, participants who had previously been jailed for IPV and controls were compared for testosterone and cortisol levels, tested for 2D:4D ratio (as an indicator of masculinization), and given several trait questionnaires and neuropsychological tests related to executive functions and theory of mind. After performing the Trier Social Stress Test (TSST), IPV perpetrators experienced decreases in salivary testosterone (T) levels, a moderate worsening of mood, slight anxiety, and a salivary cortisol (C) level increase. Moreover, high basal T was related with high levels of anger and anxiety and worse mood. However, that basal mood does not significantly alter T levels in response to stress. Nonetheless, controls experienced smaller changes in T and larger changes in C and psychological mood. With respect to neuropsychological and cognitive empathic features, IPV perpetrators showed poorer executive performance and emotional recognition than controls. In addition, deficits in both neuropsychological domains were positively associated. Regarding emotional empathy, IPV perpetrators showed higher levels of personal distress than controls. The 2D:4D ratio was lower in IPV perpetrators than in controls. Moreover, only in the former a smaller 2D:4D ratio was related to large increases in T in response to stress and poor emotional recognition. Together with social aspects involved in IPV, differences in psychobiological variables and their relationships could play a relevant role in the onset and perpetuation of violent behavior.

Abstract
Alcohol consumption, a larger history of childhood parental rejection, and high prenatal androgen exposure have been linked with facilitation and high risk of recidivism in intimate partner violence (IPV) perpetrators. Participants were distributed into two groups according to their alcohol consumption scores as high (HA) and low (LA). HA presented a higher history of childhood parental rejection, prenatal masculinization (smaller 2D:4D ratio), and violence-related scores than LA IPV perpetrators. Nonetheless, the former showed poor socio-cognitive skills performance (cognitive flexibility, emotional recognition and cognitive empathy). Particularly in HA IPV perpetrators, the history of childhood parental rejection was associated with high hostile sexism and low cognitive empathy. Moreover, a masculinized 2D:4D ratio was associated with high anger expression and low cognitive empathy. Parental rejection during childhood and early androgen exposure are relevant factors for the development of violence and the lack of adequate empathy in adulthood. Furthermore, alcohol abuse plays a key role in the development of socio-cognitive impairments and in the proneness to violence and its recidivism. These findings contribute to new coadjutant violence intervention programs, focused on the rehabilitation of basic executive functions and emotional decoding processes and on the treatment of alcohol dependence.
