Low blood glucose and fatigue accumulation at peak hours of occupational trauma in secondary industry workers

Objectives. The incidence of occupational traumatic injuries caused by human error has been reported to occur at 11:00 and 8–9 h after commencing work. Impaired attention is closely related to the incidence of these accidents. Therefore, this study aimed to clarify the changes in blood glucose, fatigue and stress response hormone levels over time among workers in a secondary industry. Methods. The blood glucose and subjective fatigue levels of 26 male secondary-industry workers were measured on workdays. In addition, the cortisol and dehydroepiandrosterone levels in saliva were measured on one workday and one holiday. Results. Blood glucose levels at 11:00 and 17:30 on the workday were significantly lower than those at 09:30. Moreover, hypoglycemia was observed in some participants. A significant increase in subjective fatigue levels was observed during the workday. However, no significant differences in salivary cortisol levels were observed between the workday and the holiday at any time point. Conclusions. Blood glucose levels decreased and subjective fatigue levels increased at the time points that occupational accidents were reported to occur most frequently during work. These factors may contribute to human errors due to impaired attentional function.

Hair steroid before and after COVID-19 in preschoolers: the moderation of family characteristics

BackgroundFrequent or prolonged exposure to stressors may jeopardize young children’s health. The onset of the COVID-19 pandemic, coupled with disruptions in daily routines and social isolation resulting from public health preventive measures, have raised concerns about its potential impact on children’ experienced stress, particularly for young children and vulnerable families. However, whether the pandemic was accompanied by changes in physiological stress remains unknown as perceived stress is not a good proxy of physiological stress. This study examined if preschoolers showed increasing hair steroid concentrations following the onset of the COVID-19 pandemic and whether family characteristics may have exacerbated or buffered these changes. Methods136 preschoolers (2–4 years) provided hair for steroid measurement (cortisol, dehydroepiandrosterone (DHEA), cortisone, cortisol-to-DHEA ratio, cortisol-to-cortisone ratio) in October-November 2019 (T0) and in July-August 2020 (T1). A 2-centimeter hair segment was analyzed, reflecting steroid production over the two months leading up to collection. Family income, conflict resolution and lack of cohesion, as well as parents’ COVID-19 stress were reported by parents. Linear mixed models for repeated measures and Bayes factors were used. ResultsNo significant changes were noted from before to after the onset of the COVID-19 pandemic for most hair steroids. However, a moderating role of family conflict resolution was noted. Children living with parents with a better ability to resolve conflicts had lower levels of DHEA compared to those who had more difficulty managing conflicts. Additionally, lower levels of family cohesion and income were linked to some steroids, especially DHEA, suggesting that these factors may relate to children’s physiological stress. Finally, boys had higher DHEA levels than girls. ConclusionOur findings suggest that stress biomarkers were comparable from before to during the COVID-19 pandemic. This observation holds true despite the pandemic being perceived by many as a novel, unpredictable, and potentially threatening event. Findings further suggest that family characteristics are associated with hair steroid, especially DHEA, which deserves further investigation.

Androgen synthesis cell-specific CREBZF deficiency alters adrenal cortex steroid secretion and develops behavioral abnormalities in adult male mice.

The global challenge of male infertility is escalating, notably due to the decreased testosterone (T) synthesis in testicular Leydig cells under stress, underscoring the critical need for a more profound understanding of its regulatory mechanisms. CREBZF, a novel basic region-leucine zipper transcription factor, regulates testosterone synthesis in mouse Leydig cells invitro; however, further validation through invivo experiments is essential. Our study utilized Cyp17a1-Cre to knock out CREBZF in androgen-synthesis cells and explored the physiological roles of CREBZF in fertility, steroid hormone synthesis, and behaviors in adult male mice. Conditional knockout (cKO) CREBZF did not affect fertility and serum testosterone level in male mice. Primary Leydig cells isolated from CREBZF-cKO mice showed impaired testosterone secretion and decreased mRNA levels of Star, Cyp17a1, and Hsd3b1. Loss of CREBZF resulted in thickening of the adrenal cortex, especially X-zone, with elevated serum corticosterone and dehydroepiandrosterone levels and decreased serum dehydroepiandrosterone sulfate levels. Immunohistochemical staining revealed increased expression of StAR, Cyp11a1, and 17β-Hsd3 in the adrenal cortex of CREBZF-cKO mice, while the expression of AR was significantly reduced. Along with the histological changes and abnormal steroid levels in the adrenal gland, CREBZF-cKO mice showed higher anxiety-like behavior and impaired memory in the elevated plus maze and Barnes maze, respectively. In summary, CREBZF is dispensable for fertility, and CREBZF deficiency in Leydig cells promotes adrenal function in adult male mice. These results shed light on the requirement of CREBZF for fertility, adrenal steroid synthesis, and stress response in adult male mice, and contribute to understanding the crosstalk between testes and adrenal glands.

Sex-specific association of serum dehydroepiandrosterone and its sulfate levels with osteoporosis in type 2 diabetes.

This study is to investigate the relation between serum dehydroepiandrosterone (DHEA) and its sulfate (DHEAS) levels and the risk of osteoporosis in patients with T2DM. This cross-sectional study involved 938 hospitalized patients with T2DM. Linear regression models were used to explore the relationship between DHEA and DHEAS and the BMD at different skeletal sites. Multinominal logistic regression models and the restricted cubic spline (RCS) were used to evaluate the associations of DHEA and DHEAS with the risks of osteopenia and/or osteoporosis. In postmenopausal women with T2DM, after adjustment for confounders including testosterone and estradiol, DHEA showed a significant positive correlation with lumbar spine BMD (P = 0.013). Moreover, DHEAS exhibited significant positive correlations with BMD at three skeletal sites: including femoral neck, total hip, and lumbar spine (all P < 0.05). Low DHEA and DHEAS levels were associated with increased risk of osteopenia and/or osteoporosis (all P < 0.05) and the risk of osteoporosis gradually decreased with increasing DHEAS levels (P overall = 0.018, P-nonlinear = 0.559). However, DHEA and DHEAS levels in men over the age of 50 with T2DM were not associated with any of above outcomes. In patients with T2DM, independent of testosterone and estradiol, higher DHEA and DHEAS levels are associated with higher BMD and lower risk of osteopenia/osteoporosis in postmenopausal women but not men over the age of 50.

Examining parental stress and its link to hair cortisol and DHEA levels in kindergartners

Background Parental work-family conflict (WFC) and parental household income have been linked to negative outcomes for children. So far, no study has associated these two stressors with the hair concentration of cortisol (HCC) and dehydroepiandrosterone (DHEA) in kindergarteners as a measurement of their objective stress. Methods and measures 44 children (40.91% female) with a mean age of 5.16 years and their parents participated in this cross-sectional study. Children’s cortisol and DHEA measurements reflected the hormones produced over the past two months. Parents filled out questionnaires concerning their WFC and parenting behavior. Results Higher maternal WFC and a lower parental net household income were negatively associated with the DHEA and positively with HCC/DHEA ratio of their children. No significant associations were found between HCC and any included variables. Paternal WFC had no impact on the stress hormones and negatively affected parenting behavior of both parents. Levels of stress hormones were not correlated with parenting behavior. Conclusion The present results indicated a higher stress exposure in children of mothers with a higher WFC and lower net household income. Conceivably, this may have led to an accumulation of allostatic load. Potential influences of demographic variables on the children’s hormones are discussed.

An 8-week community-based resilience group intervention for Chinese parents who lost their only child: A two-armed pragmatic waitlist-control trial.

This study developed and evaluated a structured, 8-week community-based resilience group intervention for Chinese parents who have lost their only child and exhibit extended bereavement and suboptimal levels of resilience. Eighty parents were recruited from two communities and allocated to the intervention group (n = 42) or the waitlist-control group (n = 38). The 8-week community-based resilience group intervention was developed based on Kumpfer's resilience theory and previous studies. The primary outcomes were resilience and depression, and the secondary outcomes were posttraumatic growth (PTG), subjective well-being (SWB), social avoidance (SAD), sleep quality, and serum dehydroepiandrosterone (DHEA) levels. Outcomes were assessed at four time points: before (T0), immediately after (T1), 3 months after (T2), and 12 months after (T3) the intervention. The data were analyzed following the intention-to-treat principle. The general linear model results indicated a significant Group × Time interaction effect on resilience, depression, PTG, SWB, and SAD, with medium and large effect sizes (Cohen's d: 0.58-1.41). Those in the intervention group experienced better resilience from T1 to T2 and better depression, PTG, SWB, and SAD from T1 to T3 compared to the waitlist-control group. No significant differences were found between groups over time for sleep quality and DHEA levels. This intervention effectively increased resilience by T2 and improved PTG, SWB, depression, and SAD by T3 compared with control group, which can be implemented in the local community setting and collaborated with social workers to assist bereaved parents in the future.

Clinical characteristics and salivary biomarkers of burning mouth syndrome.

To investigate the clinical characteristics and salivary biomarkers in each type of burning mouth syndrome (BMS) patients. Ninety-eight postmenopausal female patients with BMS were included. Fifty and 21 patients were assigned to the primary and secondary groups, respectively. Twenty-seven patients with both primary and secondary characteristics were assigned to the intermediate group. Comprehensive clinical characteristics and salivary biomarkers were analyzed. Significant differences in age, proportion of hyposalivator patients based on unstimulated whole saliva (UWS), symptom distribution, severties of burning sensation and effect of oral complaints in daily life (Eff-life), and positive symptom distress index (PSDI) were observed among the three groups. The primary group had significant higher UWS flow rate, fewer UWS hyposalivator proportions, and lesser severity of Eff-life than the secondary group. The intermediate group had significantly greater intensities of burning sensation and Eff-life and higher PSDI score than did the primary group. The primary group had significantly higher cortisol and dehydroepiandrosterone (DHEA) levels in stimulated whole saliva than did the secondary group. This study's findings show that clinical characteristics differentiate each BMS type. Cortisol and DHEA levels are potential salivary biomarkers for discriminating between the primary and secondary types of BMS.

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

ObjectiveAnxiety 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.MethodsA 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.Results147 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) (β = 0.332, p < 0.001) and fatigue (β = 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 β = 0.319, p = 0.004; PTSS β = 0.396, p = 0.001; fatigue β = 0.289, p = 0.027) and those undergoing chemotherapy (DHEA β = 0.346, p = 0.001; PTSS β = 0.407, p = 0.001; fatigue β = 0.326, p = 0.011).ConclusionsThe 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.

The cortisol/DHEA ratio mediates the association between early life stress and externalizing problems in adolescent boys

BackgroundDespite evidence that early life stress (ELS) can influence the functioning of the hypothalamic-pituitary-adrenal (HPA) axis and increase maladaptive behaviors in adolescence, less attention has been paid to the role of the coordinated effects of the two primary adrenal hormones, cortisol and dehydroepiandrosterone (DHEA), in these associations. Methods138 typically developing adolescents (76 females) reported the stressful events experienced during childhood and early adolescence across 30 domains. Two years later we assessed levels of externalizing problems and obtained salivary levels of cortisol and DHEA. Using causal moderated mediation analyses, we examined whether the ratio of cortisol to DHEA (CD ratio) mediates the association between ELS and subsequent externalizing problems. ResultsWe found that ELS is associated with both a lower CD ratio and more externalizing problems. Importantly, a lower CD ratio mediated the association between ELS and externalizing problems in boys. ConclusionsAn imbalance in adrenal hormones may be a mechanism through which ELS leads to an increase in externalizing problems in adolescent boys. These findings underscore the utility of using the CD ratio to index HPA-axis functioning.

Analysis of Endocrine and Inflammatory Markers in Preserved Ratio Impaired Spirometry.

Chronic Obstructive Pulmonary Disease (COPD) is a disease of the lungs characterized by chronic airflow obstruction. Individuals with preserved ratio impaired spirometry (PRISm) may be at risk for developing COPD. This study aimed to characterize PRISm and COPD patients in terms of their immune response and endocrine profile to identify differences extending beyond lung function. The participants performed the clinical assessment, pulmonary function test, and blood collection to determine serum hormone levels and concentrations of cytokine. Differences were observed in the nutritional status, lung function, and comorbidity. There were no differences in IL-6, IL-8, IL-10, IL-12, and TNF levels between PRISm and COPD groups. Both PRISm and COPD patients have lower dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEA-S) levels than controls. Correlation analysis of PRISm and COPD patients revealed positive correlations between serum levels of DHEA-S and DHEA, with forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC), which negatively correlated with IL-8 levels. The results indicated that despite differences in lung function parameters, the PRISm and COPD groups exhibited similarities in endocrine profile alterations. This study represents the first attempt to link endocrine with immune markers and lung function in individuals with PRISm.

Effects of Exercise Intensity Differences in Forest Therapy Programs on Immunoglobulin A and Dehydroepiandrosterone Levels in Older Adults

The purpose of this study was to examine the effects of exercise intensity and the duration of an exercise-based forest therapy program on physiological changes in older adults. The forest therapy program consisted of 20 sessions over 10 weeks. Forty-one older adults aged 65 years and older were divided into no treatment (daily activity group) and experimental (forest therapy) groups. The experimental group was further divided into the medium-intensity forest exercise group and the high-intensity forest exercise group to analyze physiological changes according to exercise intensity and duration. The physiological changes were analyzed by collecting saliva and measuring changes in the levels of immunoglobulin A and dehydroepiandrosterone, a hormone used to predict aging. Changes within the daily activity group and the forest therapy group after their respective exercises were analyzed using paired t-tests. Saliva testing was performed before and in weeks 5 and 10 of the program and analyzed using a repeated measures analysis of variance to assess the effects of the forest therapy on the medium-intensity forest exercise group and the high-intensity forest exercise group based on the duration of exercise. As a result of the study, a significant increase in immunoglobulin A was observed in the medium-intensity forest exercise group. The daily activity group and the high-intensity forest exercise group showed an increase, but there was very little change and no significance. Changes in dehydroepiandrosterone decreased in the daily activity group and significantly increased in the moderate-intensity forest exercise group at 5 and 10 weeks, showing that regular moderate-intensity forest exercise has an effect on dehydroepiandrosterone. The high-intensity forest exercise group improved over time, but no significant level of change was observed. This study shows that forest exercise has a beneficial effect on immunoglobulin A and dehydroepiandrosterone levels in older adults.

Indications of Endocrine Disruptor Effects of JP-5 Jet Fuel Using a Rat-Model Reproductive Study and an In Vitro Human Hormone Receptor Assay.

Recent events concerning jet fuel contamination of drinking water have shown that we need a better understanding of the effects of ingested jet fuel. To this end, a reproductive study with ingested jet fuel in rats was undertaken with relatively high concentrations of Jet Propellant (JP)-5 along with a human estrogen receptor activation in vitro assay using JP-5, JP-8, and an alternative jet fuel derived from the camelina plant referred to as HydroRenewable Jet (HRJ) fuel, to help evaluate potential effects of ingested jet fuel. The results of the in vivo study provide evidence that JP-5 can act as an endocrine disruptor, with specific observations including altered hormone levels with JP-5 exposure (significantly lower estradiol levels in male rats and significantly increased Dehydroepiandrosterone levels in females), and a decreased male/female offspring ratio. The in vitro hormone receptor activation assay indicated that JP-5 and JP-8 are capable of upregulating human estrogen receptor (ER) activity, while HRJ was not active in the ER assay. The jet fuels were not able to activate androgen or glucocorticoid receptors in further in vitro assays. These results infer potential endocrine disruption associated with JP-5, with activation of the estrogen receptor as one potential mechanism of action.

High Pretreatment DHEA Is Associated with Inferior Immunotherapy Response in Metastatic Non-Small Cell Lung Cancer.

Background: Sex difference in the immune response may influence patients' response to immune checkpoint inhibitors (ICIs). We conducted a prospective observation study to determine the correlation between pretreatment sex hormone levels and response to ICIs in metastatic non-small cell lung cancer (NSCLC). Method: Pretreatment plasma samples from 61 patients with newly diagnosed NSCLC prior to ICI therapy were collected. Six sex hormone levels [pyrazole triol, 17 β-estradiol, 5-androstenediol, 3β-androstenediol, dehydroepiandrosterone (DHEA), and S-equol] were measured using liquid chromatography coupled to high-resolution mass spectrometry (LC-HRMS). Overall survival (OS) and progression-free survival (PFS) were compared between the high- and low-level groups in the whole cohort. Result: Among the six sex hormones measured, DHEA levels were significantly higher among patients without clinical benefits in the discovery cohort; the remaining sex hormones did not differ significantly. In the whole cohort, median PFS was 22 months for patients with low DHEA levels vs. 3.8 months for those with high DHEA [hazard ratio, 14.23 (95% CI, 4.7-43); p < 0.001]. A significant association was also observed for OS [hazard ratio, 8.2 (95% CI, 2.89-23.35); p < 0.0001]. Conclusions: High pretreatment plasma DHEA levels were associated with poor clinical outcomes for patients with metastatic NSCLC treated with ICIs.

(273) Influences of Oral Dehydroepiandrosterone (DHEA) Administration on Hormonal Profile, Menopausal Clinical Symptoms and Sexual Function in Early Postmenopausal Symptomatic Women

Abstract Introduction Dehydroepiandrosterone (DHEA) and its sulfate (DHEAs) are steroid hormones secreted by the adrenal glands. The aging process is associated with decreased levels of DHEA and DHEAs, which are the initial causes of many age-related changes. Objective We aimed to evaluate the effects of oral administration of DHEA (50mg/day) on hormonal profile, menopausal clinical symptoms and sexual function in early postmenopausal symptomatic Caucasian women at baseline and after 2, 4 and 6 months of treatment. Methods For our prospective clinical trial, 42 symptomatic early postmenopausal women (50–55±3.5 years) were selected. Participants were divided into two groups. The study group (n-22) received oral DHEA 50mg/day for 6 months and the control group (n-20) received placebo. Serum levels of DHEA, DHEAs, androstenedione (A4), allopregnanolone (3α,5α- THP), progesterone (P4), 17OH progesterone (17OHP), cortisol, testosterone (T), dihydrotestosterone (DHT), estrone (E1), estradiol (E2), SHBG, LH, FSH and β-Endorphin were determined at baseline and after 2, 4 and 6 months of treatment. The results of the Menopause Rating Scale (MRS) and the McCoy Female Sexuality Questionnaire (MFSQ) were evaluated before and after the treatment. Results During the treatment period in the study group, a progressive increase in serum levels of DHEA, DHEAs, A4, T, DHT, E2, E1, 3α,5α-THP and β-Endorphin were observed. P4 and 17OHP levels showed only a slight increase. By the 4th month of treatment and final data, a decrease in cortisol levels was observed. LH and FSH levels gradually decreased. SHBG levels remained constant. After 6 months of treatment, assessing the results of the MRS in the DHEA group showed a progressive improvement of menopausal symptoms. The results of the McCoy questionnaire were also improved in the study group. Conclusions DHEA administration had a significant effect on certain endocrine parameters in early postmenopausal symptomatic Caucasian women, was associated with improvements of menopausal physical symptoms, sexual function and psycho-emotional parameters. Our findings support the hypothesis that administration of DHEA in symptomatic postmenopausal women restores both androgenic and estrogenic milieu and reduces most of the clinical symptoms caused by the changes of these environments during postmenopausal period. On this basis we can assume, that DHEA may be considered as a potentially effective medication for MHT. However, conducting further, more specific clinical trials are needed. Disclosure No.

Unveiling the spectrum: A cross-sectional exploration of hirsutism causes in women.

Hirsutism is a common endocrine disorder and its etiology varies from benign and idiopathic disorders to serious malignant diseases. Hirsutism creates negative impact on quality of life and considerable effects on fertility. Our objective was to determine the various causes of hirsutism in women presenting at two endocrine clinics. This cross-sectional study was conducted at Baqai Institute of Diabetology and Endocrinology, Karachi and at Jinnah hospital, Lahore from August 2020 to December 2021 women between 12-45 years of age with complains of hirsutism were included in the study. Severity of Hirsutism was evaluated using modified Ferriman-Gallwey score (FG). Patients with modified FG score of 8 or more were considered having hirsutism. The study had 113 patients with a mean age of 15.50+7.29 years with 89% having moderate hirsutism (FG score 16-25). Polycystic ovaries was the most common cause of hirsutism. Common sites for hirsutism included back (83%), arms (74%), buttocks (70%), and upper abdomen (47%). High BMI (p-value <0.01) and high Dehydroepiandrosterone levels were positively associated with the severity of hirsutism (p-value of 0.006.). The various causes of hirsutism identified were polycystic ovaries, followed by idiopathic, thyroid dysfunction, congenital adrenal hyperplasia, and hyperprolactinemia; therefore, all women presenting with hirsutism should be evaluated for potential serious and curable etiologies, before embarking on a treatment plan.

Prenatal paternal anxiety symptoms predict child DHEA levels and internalizing symptoms during adrenarche.

This study examined (1) whether measures of paternal anxious and depressive symptoms collected prenatally and during a follow-up assessment when the child was in middle childhood, predict child neuroendocrine outcomes, and (2) whether neuroendocrine outcomes are intermediate factors between paternal mental health and child cognitive/behavioral outcomes. Middle childhood coincides with increased autonomy as the child transitions into grade school, and with adrenarche, as the maturing adrenal gland increases secretion of dehydroepiandrosterone (DHEA) and its sulfated metabolite (DHEA-S), hormones that are implicated in corticolimbic development which regulate emotions and cognition. Participants were recruited from a subsample of a large prospective birth cohort study (3D study). We conducted a follow-up study when children were 6-8 years old (N = 61 families, 36 boys, 25 girls). Parental symptoms of anxiety, stress and depression were assessed via validated self-report questionnaires: prenatally using an in-house anxiety questionnaire, the Perceived Stress Scale (PSS) and the Center for Epidemiologic Studies Depression (CES-D), and at the follow up, using the Beck Anxiety and Beck Depression Inventories. Children provided salivary hormone samples, and their pituitary gland volume was measured from structural Magnetic Resonance Imaging (MRI) scans. Child behaviors were measured using the Strengths and Difficulties Questionnaire and cognitive outcomes using the WISC-V. Multiple regression analyses were used to test whether paternal mental health symptoms assessed prenatally and during childhood are associated with child neuroendocrine outcomes, adjusting for maternal mental health and child sex. Indirect-effect models assessed whether neuroendocrine factors are important intermediates that link paternal mental health and cognitive/behavioral outcomes. (1) Fathers' prenatal anxiety symptoms predicted lower DHEA levels in the children, but not pituitary volume. (2) Higher prenatal paternal anxiety symptoms predicted higher child internalizing symptoms via an indirect pathway of lower child DHEA. No associations were detected between paternal anxiety symptoms measured in childhood, and neuroendocrine outcomes. No child sex differences were detected on any measure. These results highlight the often-overlooked role of paternal factors during pregnancy on child development, suggesting that paternal prenatal anxiety symptoms are associated with child neuroendocrine function and in turn internalizing symptoms that manifest at least up to middle childhood.

Serum Levels of the Steroid Hormone Dehydroepiandrosterone Are Associated with Psychological Trauma and Lymphocyte Telomere Integrity in Women Suffering from Depression.

Emerging studies highlight the telomere system as an aging mechanism underlying the association between exposure to psychological trauma and the development of a wide range of physical and mental disorders, including major depressive disorder (MDD). Here, we investigated associations of circulating levels of the steroid hormone dehydroepiandrosterone (DHEA) with immune cell telomere length (TL) in the context of lifetime trauma exposure and MDD. Lifetime traumatic events (trauma load) were assessed using the Essener Trauma Inventory in n = 22 postmenopausal female inpatients with MDD and n = 22 non-depressed controls. All women completed the Beck's Depression Inventory II to assess the severity of current depressive symptoms. DHEA concentration in serum was measured by immunoassay, and TL was quantified in kilobase units using quantitative fluorescent in situ hybridization in total peripheral blood mononuclear cells (PBMC) and in selected T-cell subpopulations isolated by FACS separation. Higher trauma load was significantly associated with lower DHEA concentration, which in turn was linked to more depression-related fatigue. Furthermore, DHEA concentration was positively and significantly associated with TL in memory CD4+ T cells as well as in naïve and memory CD8+ T cells, but not in naïve CD4+ T cells and total PBMC. Mediational analysis suggested that DHEA concentration is a mediator in the relationship between trauma load and memory CD8+ T-cell TL. The current findings suggest a potential role of DHEA as a biological resilience factor that may exert beneficial effects on telomere integrity, especially in conditions related to distress.

Role of IL-1β, Prolactin and DHEA in men Patients Infected with Toxoplasmosis

Toxoplasma gondii has a worldwide distribution and it is one of the most prevalent infectious agents in Iraq, as it is found in various mammals, fish, and terrestrial and water birds. Cats are the only definitive host for the parasite that throws the infective phase into the environment. The primary aim of this study was to determine the serum levels of IL-1β, prolactin, Dehydroepiandrosterone (DHEA) in patients and healthy group.The study was conducted on 260 Males suspected of Toxoplasmosis ages ranging from 20-50 years old. All these cases were examined by measuring Toxo IgG serum levels, who attended AL-Hakeem hospital, and (30) healthy males as the control group, collected randomly from AL-Najaf province, these samples were collected from March 2023 to August 2023. Any patient was using the drug or undergoing disease removal from the current study. The current study revealed that the concentration of IL-1β inpatients infected with Toxoplasmosis were significant increase (P&lt;0.05) compared to the control group, but the concentration of (prolactin) in patients infected with toxoplasmosis were significant decrease (P&lt;0.05) is compared to the control group. Also, it revealed that the DHEA levels were elevated but non significantly in samples infected with Toxoplasmosis compared to the control group. The current study has concluded that infection with Toxoplasmosis may be a risk factor. A chronic T. gondii infection is associated with variations in levels of serum prolactin and these variations may influence the immune system by IL-1β increase the susceptibility to Toxoplasmosis infection.

Efficacy of antioxidant supplementation in improving endocrine, hormonal, inflammatory, and metabolic statuses of PCOS: a meta-analysis and systematic review.

Background and aim: A large number of recent studies have reported on the use of antioxidants in patients with polycystic ovary syndrome (PCOS). This study aimed to evaluate the antioxidant effects on PCOS. Methods: We searched PubMed, Embase, Web of Science, and The Cochrane Library to identify randomized controlled trials investigating the use of antioxidants in treating PCOS. Statistical analysis was performed using Review Manager 5.4. Stata17.0 software was used to conduct sensitivity analyses. Results: This meta-analysis included 49 articles and 62 studies. The sample comprised 1657 patients with PCOS from the antioxidant group and 1619 with PCOS from the placebo group. The meta-analysis revealed that the fasting blood glucose levels [standardized mean difference (SMD): -0.31, 95% confidence interval (CI): -0.39 to -0.22, P < 0.00001], the homeostatic model assessment of insulin resistance (SMD: -0.68, 95% CI: -0.87 to -0.50], P < 0.00001), and insulin levels (SMD: -0.68, 95% CI: -0.79 to -0.58, P < 0.00001) were significantly lower in patients with PCOS taking antioxidants than those in the placebo group. Further, total cholesterol levels (SMD: -0.38, 95% CI: -0.56 to -0.20, P < 0.001), low-density lipoprotein cholesterol levels (SMD: -0.24, 95% CI: -0.37 to -0.10, P = 0.0008), and very low-density lipoprotein levels (SMD: -0.53, 95% CI: -0.65 to -0.41, P < 0.00001) were lower in patients with PCOS taking antioxidant supplements compared with the placebo group. Total testosterone (TT) level (SMD: -0.78, 95% CI: -1.15 to -0.42, P < 0.0001), dehydroepiandrosterone level (SMD: -0.42, 95% CI: -0.58 to -0.25, P < 0.00001), and mean standard deviation modified Ferriman-Gallway (MF-G scores) (SMD: -0.63, 95% CI: -0.98 to -0.28, P = 0.0004) were lower in patients taking antioxidant supplements. C-reactive protein (CRP) levels (SMD: -0.48, 95% CI: -0.63 to -0.34, P < 0.000001), body mass index [mean difference (MD): -0.27, 95% CI: -0.50 to -0.03, P = 0.03], weight (MD: -0.73, 95% CI: -1.35 to -0.11, P = 0.02), and diastolic blood pressure (MD: -3.78, 95% CI: -6.30 to -1.26, P = 0.003) were significantly lower. Moreover, the levels of sex hormone-binding protein (SMD: 0.23, 95% CI: 0.07-0.38, P = 0.004), high-density lipoprotein cholesterol (SMD: 0.11, 95% CI: 0.01-0.20, P = 0.03), total antioxidant capacity (SMD: 0.59, 95% CI: 0.31-0.87, P < 0.0001), and quantitative insulin sensitivity index (SMD: 0.01, 95% CI: 0.01-0.02, P < 0.00001) were higher in patients with PCOS who took antioxidant supplements compared with the placebo group. Antioxidant supplements did not affect other analyzed parameters in these patients, including follicle-stimulating hormone, free androgen index, nitric oxide, glutathione, malondialdehyde, and diastolic blood pressure. Conclusions: Antioxidants are beneficial in treating PCOS. Our study might provide a new treatment strategy for patients with clinical PCOS. We hope that more high-quality studies evaluating the effects of antioxidants on patients with PCOS will be conducted in the future.

Muscular Hypertrophic Effects of Oral Contraceptive Consumption in Women

Hormones have several actions in the body; among their effects on effector organs, they can control the volume of skeletal muscle. The excess of hormones, in this case exogenous ones, could be altering the effects of physical exercise on skeletal muscle hypertrophy, especially after the consumption of contraceptives. Thus, we have a general objective in this work to evaluate the effects of contraceptive consumption on hypertrophy in women. We sought an integrative literature review with studies within 2001-2021, using the PubMed and Scielo databases. Seven articles were selected for a complete and coherent reading for the development of this review. Given the studies analyzed in the present study, it was possible to observe that the effects of oral contraceptives may indeed influence muscle hypertrophy. However, it can assist in preserving soft tissues, avoiding the looseness of the anterior cruciate ligament (ACL). For individuals aiming to enhance lean muscle mass, particularly in high-performance contexts, it is advisable to consider alternative contraceptive methods that do not disrupt the natural hormonal system. In conclusion, the OC user group did not obtain significant gains in lean mass, but their levels of dehydroepiandrosterone (DHEA), sex hormone agglobulinal ligand (SHBG), and insulin-like growth factor (IGF1) decreased, with increasing levels of only cortisol. Thinking of high performance to increase lean muscle mass, another means of contraceptives that do not affect the physiological hormonal system should be used.
