The associates of anxiety among lung cancer patients: Dehydroepiandrosterone (DHEA) as a potential biomarker.

OBJECTIVE: Anxiety is a prevalent comorbidity in lung cancer (LC) patients associated with a decline in quality of life. Dehydroepiandrosterone (DHEA), a neuroactive steroid, levels rise in response to stress. Prior research on the association between DHEA and anxiety has yielded contradictory results and no study has investigated this association in LC patients. METHODS: A total of 213 patients with LC were recruited from a general hospital. Data on demographic and cancer-related variables were collected. Using the Chinese version of the Hospital Anxiety and Depression Scale (HADS), the degree of anxiety was determined. Cortisol, DHEA, and Dehydroepiandrosterone sulfate (DHEA-S) levels in saliva were measured. Adjusting for confounding variables, a multivariate regression analysis was conducted. RESULTS: 147 men and 66 women comprised our group with an average age of 63.75 years. After accounting for demographic and treatment-related factors, anxiety levels were significantly correlated with, post-traumatic stress symptoms (PTSSs) (ß = 0.332, p < 0.001) and fatigue (ß = 0.247, p = 0.02). Association between anxiety and three factors, including DHEA, PTSSs, and fatigue, was observed in patients with advanced cancer stages (III and IV) (DHEA ß = 0.319, p = 0.004; PTSS ß = 0.396, p = 0.001; fatigue ß = 0.289, p = 0.027) and those undergoing chemotherapy (DHEA ß = 0.346, p = 0.001; PTSS ß = 0.407, p = 0.001; fatigue ß = 0.326, p = 0.011). CONCLUSIONS: The association between anxiety and DHEA remained positive in advanced cancer stages and chemotherapy patients. Further study is necessary to determine whether DHEA is a potential biomarker of anxiety in LC patients.

Examination-related anticipatory levels of dehydroepiandrosterone and cortisol predict positive affect, examination marks and support-seeking in college students.

Dehydroepiandrosterone (DHEA) and cortisol release appear to have contrasting effects on stress perception during stressful tasks. This study aimed to investigate anticipatory examination stress in college students by considering DHEA, cortisol, psycho-emotional aspects and examination performance. Seventy-six students (66 females, 10 males; age range 18-25 years) provided saliva samples and completed questionnaires in two sessions 48 hours apart. During the second session, the students performed the examination. The questionnaires used were the State-Trait Anxiety Inventory, the Positive and Negative Affect Scale, and the Brief-Coping Orientation to Problems Experienced Inventory. DHEA, cortisol, anxiety and negative affect showed an anticipatory rise before the examination (all ps < 0.001). This rise of DHEA and cortisol was associated with lower positive affect (p = 0.001 and p = 0.043, respectively). However, only the DHEA anticipatory levels were linked to poorer examination marks (p = 0.020). Higher levels of the DHEA/cortisol ratio in anticipation of the examination were related to lower scores on the support-seeking strategy (p = 0.022). There was no association between DHEA and cortisol levels and anxiety, negative affect, active and avoidant coping strategies, or academic record. These results suggest that how DHEA and cortisol respond in anticipation of examination stress significantly impacts students' emotional well-being during examination periods and how they cope with stress. They also suggest that levels of DHEA in anticipation of an academic stressor have detrimental effects on stress management.

Hair androgen concentrations and depressive disorders in adolescents from the general population.

Although the link between androgens and depression is well established in adults, the effects of cofactors on this association are less clearly understood, particularly in youth. Epidemiological cohort study of adolescents in Dresden, Germany. Analyses comprised data of 985 individuals assessed at baseline and of 512 individuals at 1-year follow-up. We investigated multivariable regression models for cross-sectional and longitudinal associations of hair testosterone, dehydroepiandrosterone (DHEA), and their cortisol ratios with 12-month diagnoses of major depressive disorder (MDD) and MDD without any anxiety disorder assessed with standardized diagnostic interview (DIA-X-5), and with dimensional depression scores (PHQ-9, PROMIS), separately for males and females. The potential moderating effect of social support was determined. Cross-sectional analyses yielded inverse associations of testosterone and DHEA with MDD and MDD without any anxiety disorders in males. In cross-sectional and longitudinal analyses, baseline ratio cortisol/DHEA was significantly, inversely associated to PROMIS-depression in males. Only cross-sectional associations for ratio cortisol/DHEA and PROMIS-depression remained significant after Bonferroni-Holm correction. No robust associations were observed in female participants. Social support exerted no consistent moderating effect on the investigated association. The present observational cohort study showed no consistent association of hair androgen concentrations with depressive disorders in adolescents. However, findings provide some support for the association between the cortisol/DHEA ratio and depression in males. Longitudinal research designs in large samples are needed to understand the interplay between androgens, depression, and developmental and social factors in youth.

Cortisol/DHEA ratio in morbidly obese patients before and after bariatric surgery: Relation to metabolic parameters and cardiovascular performance.

INTRODUCTION: Bariatric surgery (BS) is the most effective therapy for morbid obesity. Cortisol and DHEA are steroid hormones with opposing effects, thus using Cortisol/DHEA ratio (C/D) rather than the use of either hormone alone has been found to predict health outcomes more reliably. It was interesting to study C/D as an indicator of favorable metabolic and cardiovascular outcomes after BS. OBJECTIVE: To assess C/D in morbidly obese patients before and after BS in relation to metabolic parameters and cardiovascular performance. PATIENTS AND METHODS: Forty morbidly obese patients were followed prospectively for 1 year after BS. Fasting blood glucose (FBG), fasting insulin (FI), C/D, lipid profile, high-sensitive CRP (hs-CRP), and echocardiography were done before BS and at 3 months and 1 year post BS. RESULTS: A total of 40 morbidly obese patients undergone sleeve gastrectomy. Blood pressure, FBG, FI, hs-CRP, C/D were significantly decreased after BS (p < 0.001). At 1 year post BS; significant reduction in left ventricular posterior wall thickness (LVPW) (p < 0.001), left ventricular mass (LVM) (p = 0.003), relative wall thickness (RWT) (p < 0.001) with a significant improvement in early diastolic velocity (E) (p < 0.001), early diastolic velocity/late diastolic velocity (E/A) (p = 0.01). After BS; C/D significantly positively correlated with FBG (p = 0.019), hs-CRP (p = 0.008), interventricular septum thickness (IVS) (p = 0.028), LVPW (p = 0.028), relative wall thickness (RWT) (p = 0.022), early diastolic velocity /early diastolic velocity (E') measured by pulsed tissue Doppler imaging (E/E') (p = 0.001), and significantly negatively correlated with E' (p = 0.032). C/D was the single significant independent variable affecting E' and E/E' post BS. CONCLUSION: C/D can be used as a surrogate marker of the improved FBG and the resolution of inflammation post BS. C/D is an independent predictor of diastolic function improvement post BS.

A Pt-Ir nanocube amplified lateral flow immunoassay for dehydroepiandrosterone.

The traditional gold-nanoparticle-based lateral flow immunoassay (LFIA) cannot satisfy the requirements for the sensitive detection of dehydroepiandrosterone (DHEA) in human urine. To enhance the sensitivity of the LFIA, platinum-iridium nanocubes (Pt-Ir NCs) with high catalytic efficiency and stability were synthesized and labelled with polyclonal antibody (pAb) to form a pAb-Pt-Ir probe. For the detection of DHEA, a novel LFIA with Pt-Ir NCs as an optical label and an enhanced LFIA in which the peroxidase-like activity of the Pt-Ir NCs was triggered by the introduction of the chromogenic substrate 3-amino-9-ethyl-carbazole (AEC) were developed and compared with a LFIA with platinum nanocubes (PtNCs) as an optical label. The visual limit of detection was 0.5 ng mL-1 for Pt-Ir-LFIA and 0.05 ng mL-1 for AEC-enhanced Pt-Ir-LFIA, in comparison to 100 ng mL-1 for PtNCs-LFIA and 50 ng mL-1 for AEC-enhanced PtNCs-LFIA. The average recoveries from spiked urine samples ranged from 90.8% to 110.4%, with a coefficient of variation below 12.6%, suggesting the accuracy and reliability of our developed immunoassay. Achieving excellent sensitivity, specificity, and reproducibility, Pt-Ir-LFIA provided a promising platform for monitoring DHEA.

Determination of anabolic androgenic steroids in dietary supplements and external drugs by magnetic solid-phase extraction combined with high-performance liquid chromatography-tandem mass spectrometry.

The widespread abuse of anabolic androgenic steroids by healthy people leads to the risk of major mood disorders and heart failure; thus, the determination of anabolic androgenic steroids is vital. In this study, 17 anabolic androgenic steroids in dietary supplements and external drugs were identified, and their concentration was determined. For this purpose, polyaniline-coated magnetic nanoparticles were prepared and then subjected to magnetic solid-phase extraction combined with high-performance liquid chromatography-tandem mass spectrometry. The experimental parameters of magnetic solid-phase extraction were studied in detail, and the optimal conditions were established. Under the optimal conditions, the limits of detection were in the range of 0.001-0.02 µg/L, with relative standard deviations of 5.52-11.6% (n = 7) for all the steroids, and the enrichment factors were in the range of 20.0-24.8. The developed method was then successfully applied for the determination of 17 anabolic androgenic steroids in real samples, and dehydroepiandrosterone (prasterone) was detected in a commercially available external drug.

Organ- and Age-Specific Differences of Dioscorea polystachya Compounds Measured by UPLC-QTOF/MS.

Dioscorea polystachya, named Chinese yam, is widely cultivated as a functional food and natural medicine in China. There is currently little information about the chemical characteristics of Dioscorea polystachya in different organs (tuber cortex and tuber flesh) and at various ages. In this study, an ultra-high-performance liquid chromatography coupled to quadrupole time-of-flight mass spectrometry (UPLC-QTOF/MS) was used to profile chemical compounds in Dioscorea polystachya. As a result, thirty-eight compounds were detected in yam tuber cortex and tuber flesh. More compounds were detected in yam tuber cortex than in tuber flesh. Compounds such as dehydroepiandrosterone, allantoin and flavonoids were selected as biomarker candidates. Dehydroepiandrosterone was found more abundant in tuber flesh, while allantoin and flavonoids showed higher levels in tuber cortex. Furthermore, the levels of dioscin, malvalic acid and sucrose differed significantly among age groups and were highest in the tubers at 2 years. While the levels of allantoin, adenosine and glutamine increased with the growing years and were highest at 4 years. Thus, 2-year old Dioscorea polystachya tubers could be harvested to prepare dioscin, malvalic acid and sucrose supplements. The 4-year-old Dioscorea polystachya tubers would be the best choice for obtaining a large amount of allantoin and adenosine in industrial production.

Pubertal recalibration of cortisol-DHEA coupling in previously-institutionalized children.

As a period of heightened plasticity, puberty may provide a window of opportunity for recalibration of the hypothalamic-pituitary-adrenal (HPA) axis to current conditions. Our group has recently documented evidence for pubertal recalibration of HPA axis reactivity among children internationally adopted as infants from institutions into supportive, well-resourced homes. As a first step at examining potential mechanisms by which puberty may facilitate recalibration of the HPA axis, the current study assessed whether previously-institutionalized (PI) children differed from non-adopted (NA) comparison children in levels of the adrenal steroid hormone dehydroepiandrosterone (DHEA) and in its intra-individual covariation (coupling) with cortisol by adrenal pubertal stage. In an accelerated longitudinal design, 7- to 15-year-olds completed up to 3 annual assessments, which included nurse-conducted pubertal staging and the Modified Trier Social Stress Test for Children (TSST-M). Adrenal (pubic hair) rather than gonadal pubertal stage scores were used in the analysis. Paired salivary cortisol-DHEA samples were available at 60-80 min post-TSST-M. NA and PI children did not differ in DHEA levels, which were higher among children at more advanced pubertal stages (averaged across the sessions) for both groups. For NA children, post-stressor cortisol and DHEA were positively coupled across sessions at all average adrenal pubertal stages. For PI children who were, on average, at earlier adrenal pubertal stages, post-stressor cortisol and DHEA were not coupled, but PI children who were at later pubertal stages demonstrated positive cortisol-DHEA coupling similar to that of the NA children. We suggest that these findings provide insights into processes which may underlie pubertal recalibration of the HPA axis.

Flexible, low volume detection of chronobiology biomarkers from human sweat.

Chronobiology is defined as the temporal fluctuations occurring in the human physiology due to the circadian cycle. These fluctuations are good indicators of the functioning of the Hypothalamic-Pituitary-Adrenal axis (HPA axis) and can be tracked by using biomarkers: cortisol and DHEA. Low volume tracking systems will be beneficial for patients exposed to chronic stress, patients suffering from endocrine conditions manifested by circadian disruption and act as a lifestyle monitoring tool. The sensor system demonstrated in this work was an affinity-based system, characterized using EIS (Electrochemical Impedance Spectroscopy).The sensor can detect cortisol and DHEA in the physiologically relevant ranges i.e. 8-200 ng ml-1 and 2-131 ng ml-1 respectively. Thus, the senor is a non-invasive, label free, cost-effective solution for tracking chronobiology for circadian diagnostics.

Does Type of Menopause Affect the Sex Lives of Women?

BACKGROUND The aim of this study was to investigate factors affecting the sex lives of middle-aged women, and whether surgical menopause affects sexual function differently from natural menopause, by comparing effects on sexual performance of women with similar demographic features. MATERIAL AND METHODS The study included 151 women with surgical menopause (SM), 357 women with natural menopause (NM), and 186 perimenopausal women (PM). The women were asked to complete a 6-question survey of sexual performance parameters. The relationship between the demographic and clinical features and hormone levels of the groups and sexual function parameters were evaluated. We also compared these parameters between the 3 study groups, and paired comparisons were made between the SM group and the NM group. RESULTS Demographic features, serum DHEA-S, total testosterone, and FSH levels were found to have statistically significant effects on sexual performance of women (p<0.05). The sexual function scores for the frequency of sexual desire, coitus, and orgasm were significantly higher in the PM group, whereas vaginal lubrication scores were lower compared to the NM and SM group (p<0.05). In paired comparison of NM and SM, the scores for the frequency of coitus, orgasm, and vaginal lubrication were significantly higher in the SM group, while sexual desire frequency scores were higher in the NM group (p<0.05). CONCLUSIONS Our study approached to this topic in an extended manner and found significant relationships between several demographic-clinical and hormonal factors. SM was found to not affect female sexual performance, except for sexual desire, more than NM.

Psychological and Physiological Predictors of Resilience in Navy SEAL Training.

This research examines resilience from both cognitive and physiological perspectives and the relative importance of resilience for progression within an extremely physical training environment for 116 individuals. Our study provides a unique contribution as an examination of the combined effects of psychological and physiological resilience in the success of individuals in the first phase of a military special operations training course, the Navy's Basic Underwater Demolition/SEAL (BUD/S) course. Our study used the Connor-Davidson Resilience Scale (CD-RISC) for the psychological assessment and a blood sample to measure the concentrations of cortisol, DHEA and BDNF, each associated with stress adaptation and neuronal integrity. Our contributions include: heeding the call for more extensive research for resilience, examining physiological markers as predictors in training situations, combining psychological and physiological resilience into a single metric to assess resilience, and providing empirical support for the vital role of resilience in both stamina and persistence in training. Our findings indicate that both psychological and physiological resilience can be important predictors of persistence individually, but combining the measures provides a more holistic view to predict the success of an individual in this intensive training program. The present study has implications not only for the military community, but also for those individuals seeking elite performance in a broad array of fields, like professional athletes, CEO's, and emergency response workers.

Steroid profiles by liquid chromatography-mass spectrometry of matched serum and single dominant ovarian follicular fluid from women undergoing IVF.

RESEARCH QUESTION: Can IVF outcomes be predicted from the steroid profile generated by liquid chromatography-mass spectrometry (LC-MS/MS) from follicular fluid collected from a single dominant follicle and serum after ovarian stimulation. DESIGN: Prospective observational cohort study in which serum and follicular fluid were collected from women and used to generate steroid profiles by LC-MS/MS. A total of 93 consecutive women enrolled for IVF treatment were recruited at the Fertility Unit, Royal Prince Alfred Women and Babies Hospital, Sydney between September 2014 and July 2015. Baseline and serum levels at oocyte retrieval, as well as follicular fluid samples from the largest single antral follicle, were collected. All samples underwent steroid analysis within a single batch to measure progesterone (P4), oestradiol (E2), oestrone (E1), dehydroepiandrosterone (DHEA), androstenedione (A4), testosterone (T), dihydrotestosterone (DHT), and 3 α, 5α androstanediol (3α-diol) and 3ß, 5α androstanediol (3ß-diol). RESULTS: P4, E2, E1, A4, T, DHEA and A4 were detectable in all baseline serum levels, at oocyte retrieval and in follicular fluid samples, whereas DHT, 3α-diol and 3ß-diol were only detectable in a minority of samples. The most consistent predictor of pre-transfer (number of follicles >14mm in diameter, oocytes retrieved or fertilized, day-5 blastocysts) outcomes was baseline serum anti-Müllerian hormone. In follicular fluid, E2 was a negative predictor of the number of oocytes retrieved and the number of day-5 blastocysts but no follicular fluid steroids predicted pregnancy outcome. CONCLUSIONS: None of the nine steroids measured in follicular fluid predicted pregnancy outcome in women undergoing IVF.

Adrenal function links to early postnatal growth and blood pressure at age 6 in children born extremely preterm.

BACKGROUND: Low birth weight in term-born individuals correlates with adverse cardiometabolic outcomes; excess glucocorticoid exposure has been linked to these relationships. We hypothesized that cortisol and adrenal androgens would correlate inversely with birthweight and directly with markers of cardiometabolic risk in school-aged children born extremely preterm; further, preterm-born would have increased cortisol and adrenal androgens compared to term-born children. METHODS: Saliva samples were obtained at age 6 from 219 preterm-born children followed since birth and 40 term-born children and analyzed for dehydroepiandrosterone (DHEA) and cortisol. Cortisol was also measured at home (awakening, 30' later, evening). RESULTS: For preterm-born children, cortisol and DHEA correlated inversely with weight and length Z-scores at 36 weeks PMA and positively with systolic BP. DHEA was higher in preterm-born than term-born children (boys p < 0.01; girls p = 0.04). Cortisol was similar between preterm-born and term-born at study visit; however, preterm-born children showed a blunted morning cortisol. In term-born children, DHEA correlated with BMI (p = 0.04), subscapular, and abdominal skinfold thicknesses (both p < 0.01). CONCLUSION: Cortisol and DHEA correlated inversely with early postnatal growth and directly with systolic BP in extremely preterm-born children, suggesting perinatal programming. Blunted morning cortisol may reflect NICU stress, as seen after other adverse childhood experiences (ACEs).

The Effect of Statins on Levels of Dehydroepiandrosterone (DHEA) in Women with Polycystic Ovary Syndrome: A Systematic Review and Meta-Analysis.

BACKGROUND Currently, statins are used to treat polycystic ovary syndrome (PCOS). This systematic review and meta-analysis aimed to investigate the effect of statins on serum or plasma levels of dehydroepiandrosterone (DHEA) in women with PCOS. MATERIAL AND METHODS Databases that were searched included PubMed, Embase, and the Cochrane Library from their inception to August of 2018. Published randomized controlled trials (RCTs) were identified that evaluated the impact of statins on plasma DHEA levels in women with PCOS. The Cochrane risk of bias tool was used to assess the quality of the included RCTs. A random-effects model was used to analyze the pooled results. RESULTS Meta-analysis was performed on data from ten published studies that included 735 patients and showed that statin treatment could significantly reduce plasma DHEA levels when compared with controls (SMD, -0.43; 95% CI, -0.81-0.06; p=0.02; I²=82%). Statins were significantly more effective than placebo in reducing the levels of DHEAs. Subgroup analysis based on statin type showed that atorvastatin significantly reduced DHEA levels (SMD, -0.63; 95% CI, -1.20 - -0.05; p=0.03; I²=38%) but simvastatin did not significantly reduce DHEA levels (SMD: -0.14; 95% CI, -0.49-0.28; p=0.43; I²=77%). Subgroup analysis based on duration of treatment showed no significant difference between 12 weeks of statin treatment (SMD, -0.61; 95% CI, -1.23-0.02; p=0.06; I²=85%) and 24 weeks (SMD, -0.34; 95% CI -0.95-0.28; p=0.29; I²=83%). CONCLUSIONS Meta-analysis showed that statins significantly reduced the levels of DHEA when compared with placebo in patients with PCOS.

The effect of nonsurgical periodontal treatment on gingival crevicular fluid stress hormone levels: A prospective study.

OBJECTIVES: The purpose of this prospective study was to investigate the effect of nonsurgical periodontal treatment (PT) on anxiety/depression scale scores and on gingival crevicular fluid (GCF) cortisol (COR) and dehydroepiandrosterone (DHEA) levels. METHODS: Fifty-five participants with generalized chronic periodontitis (GCP group, n: 21), with localized chronic periodontitis (LCP group, n: 19) and with gingivitis or healthy (control group, n: 15) subjects were treated and followed up for 6 months. Clinical periodontal parameters include plaque index, gingival index, bleeding on probing, probing depth and attachment level; psychosocial measurements include Beck Depression Inventory (BDI) and State-Trait Anxiety Inventory (STAI 1-2) psychometric instruments; hormone levels in GCF including COR and DHEA were evaluated. RESULTS: All clinical parameters were significantly decreased (except attachment loss) after PT (p < 0.05). No significant differences were observed between the two groups for STAI-1-2 and BDI scores, either at baseline or at 6 months (p > 0.05). COR levels were statistically lower following PT in GCP and LCP groups when compared to the baseline levels (p < 0.05). DHEA values at baseline and 6 months did not show significant differences. CONCLUSION: Within the limits of the study, decreased GCF COR and unchanged GCF DHEA levels were determined in nonsurgically treated patients regardless of the extent and severity of periodontitis.

Adrenal Function in Adolescence is Related to Intrauterine and Postnatal Growth.

Background and objectives: Intrauterine growth restriction is thought to be implicated in long-term programming of hypothalamic-pituitary-adrenal axis activity. We investigated adrenal function in adolescents born small for gestational age (SGA) in relation to their postnatal growth and cardiovascular parameters. Materials and Methods: Anthropometric parameters, blood pressure, heart rate, dehydroepiandrosterone sulfate (DHEAS), and cortisol levels were assessed in 102 adolescents aged 11-14 years followed from birth (47 SGA and 55 born appropriate for gestational age (AGA)). Results: Mean DHEAS levels were higher in SGA adolescents with catch-up growth (SGACU+), compared with AGA. Second-year height velocity and body mass index (BMI) gain during preschool years were positively related to DHEAS levels. Morning cortisol levels and systolic and diastolic blood pressure were higher in SGA adolescents without catch-up growth (SGACU-) compared with AGA. Second-year BMI gain was inversely, and 2-12 years increase in subscapular skinfold thickness was directly associated with cortisol levels. Size at birth and postnatal growth explained 47.8% and 38.2% of variation in DHEAS and cortisol levels, respectively. Conclusion: Adrenal function in adolescence is affected by prenatal and postnatal growth: small size at birth with postnatal catch-up growth is related to higher DHEAS secretion, whereas increased cortisol levels and blood pressure are higher in short SGA adolescents.

Investigating relations among stress, sleep and nail cortisol and DHEA.

In the current study, we present data investigating the relationships among stress, sleep disturbance, self-control, and levels of cortisol (CORT) and dehydroepiandrosterone (DHEA) in fingernail clippings. Currently, hair CORT is the only routinely used noninvasive, validated, biomarker of chronic exposure to stress-related hormones. Nail clippings represent an important potential alternative sample matrix for assessing chronic hormone exposure, as it offers a different timeline of hormone incorporation than scalp hair, and may be obtainable from populations in which hair either is lacking or is unavailable for cultural reasons. Moreover, there is established precedent for using fingernail clippings to attain biomarker data. However, the value of nail hormone assessment for psychological research is currently unknown due to a paucity of information on the relations between nail hormone concentrations and environmental or psychological variables. In the present study, we collected data from a low income, minority population (N = 47; 97% African American) to demonstrate feasibility and acceptability of nail collection and analysis of the adrenal steroids CORT and DHEA. Participants reported on perceived stress, sleep and self-control abilities. Correlational analyses suggest that exposure to stressful events, disturbances in sleep and waking were associated with higher levels of nail DHEA, while self-control was associated with higher levels of nail CORT. We discuss the potential importance of this methodology for investigating biological, behavioral, and subjective indices of stress and well-being.

Callous-unemotional traits and early life stress predict treatment effects on stress and sex hormone functioning in incarcerated male adolescents.

The stress response system is highly plastic, and hormone rhythms may "adaptively calibrate" in response to treatment. This investigation assessed whether stress and sex hormone diurnal rhythms changed over the course of behavioral treatment, and whether callous-unemotional (CU) traits and history of early adversity affected treatment results on diurnal hormone functioning in a sample of 28 incarcerated adolescent males. It was hypothesized that the treatment would have beneficial effects, such that healthier diurnal rhythms would emerge post-treatment. Diurnal cortisol, testosterone, and dehydroepiandrosterone (DHEA) were sampled two weeks after admission to the correctional/treatment facility, and again approximately four months later. Positive treatment effects were detected for the whole sample, such that testosterone dampened across treatment. CU traits predicted a non-optimal hormone response to treatment, potentially indicating biological preparedness to respond to acts of social dominance and aggression. The interaction between CU traits and adversity predicted a promising and sensitized response to treatment including increased cortisol and a steeper testosterone drop across treatment. Results suggest that stress and sex hormones are highly receptive to treatment during this window of development.

Alterations of hair cortisol and dehydroepiandrosterone in mother-infant-dyads with maternal childhood maltreatment.

BACKGROUND: Child maltreatment (CM) has severe effects on psychological and physical health. The hypothalamic-pituitary-adrenal (HPA) axis, the major stress system of the body, is dysregulated after CM. The analysis of cortisol and dehydroepiandrosterone (DHEA) in scalp hair presents a new and promising methodological approach to assess chronic HPA axis activity. This study investigated the effects of CM on HPA axis activity in the last trimester of pregnancy by measuring the two important signaling molecules, cortisol and DHEA in hair, shortly after parturition. In addition, we explored potential effects of maternal CM on her offspring's endocrine milieu during pregnancy by measuring cortisol and DHEA in newborns' hair. METHODS: CM was assessed with the Childhood Trauma Questionnaire (CTQ). Cortisol and DHEA were measured in hair samples of 94 mothers and 30 newborns, collected within six days after delivery. Associations of maternal CM on her own and her newborn's cortisol as well as DHEA concentrations in hair were analyzed with heteroscedastic regression models. RESULTS: Higher CM was associated with significantly higher DHEA levels, but not cortisol concentrations in maternal hair. Moreover, maternal CM was positively, but only as a non-significant trend, associated with higher DHEA levels in the newborns' hair. CONCLUSIONS: Results suggest that the steroid milieu of the mother, at least on the level of DHEA, is altered after CM, possibly leading to non-genomic transgenerational effects on the developing fetus in utero. Indeed, we observed on an explorative level first hints that the endocrine milieu for the developing child might be altered in CM mothers. These results need extension and replication in future studies. The measurement of hair steroids in mothers and their newborns is promising, but more research is needed to better understand the effects of a maternal history of CM on the developing fetus.

Care Transitions and Adult Day Services Moderate the Longitudinal Links between Stress Biomarkers and Family Caregivers' Functional Health.

BACKGROUND: Stress biomarkers have been linked to health and well-being. There are, however, few studies on how dysregulation in the hypothalamic-pituitary-adrenal axis and sympathetic nervous system actually affects functional health of family caregivers of persons with dementia. Further, it is not clear whether and how factors affecting caregiving stressor exposures such as care transitions and adult day services (ADS) use may affect such association. OBJECTIVE: First, to examine the association of daily stress biomarkers and functional health over time among family caregivers of persons with dementia. Second, to examine effects of care transitions and ADS use on the association between baseline stress biomarkers and functional health over time. METHODS: At baseline, caregivers provided 5 saliva samples each day during an 8-day diary study, where all caregivers were having a varying number of ADS days per week. There were 2 longitudinal follow-ups at 6 and 12 months on ADS use, care transitions, and caregivers' functional health. The average daily total output across days was computed at baseline for salivary cortisol, the sulfated form of dehydroepiandrosterone (DHEA-s), and salivary alpha amylase (sAA), which were used as predictors of caregivers' longitudinal functional limitation trajectories. Care transitions and total number of ADS days per week at baseline were considered as moderators of the associations between stress biomarkers and health over time. RESULTS: The associations between functional limitation trajectories and daily total outputs of cortisol and sAA were modified by ADS use and care transitions. Among caregivers who experienced a transition, and who used less than average ADS days per week, lower daily cortisol total output and lower daily sAA total output were associated with increasing functional limitations. Caregivers who experienced a transition but used greater than average ADS days per week did not show such patterns of association. No significant effect was found for DHEA-s. CONCLUSION: The study contributes to an important but largely unanswered question regarding implications of stress biomarkers on functional health. Assessments of the association between stress biomarkers and health among family caregivers of persons with dementia need to consider changes in stressor exposures over time, such as care transitions and ADS use.
