Premenstrual syndrome is associated with altered cortisol awakening response

Estrogen, progesterone, cortisol, brain-derived neurotrophic factor, and vascular endothelial growth factor during the luteal phase of the menstrual cycle in women with premenstrual dysphoric disorder

The interplay between ovarian hormones, stress, and inflammatory markers in developing premenstrual dysphoric disorder (PMDD) remains inadequately understood. This study investigated the associations of dynamic changes in the levels of estrogen, progesterone, cortisol, brain-derived neurotrophic factor (BDNF), and vascular endothelial growth factor (VEGF) with PMDD during the luteal phase of the menstrual cycle. A total of 58 women with PMDD and 50 healthy women were recruited in this study. These women's estrogen, progesterone, cortisol, BDNF, and VEGF levels were evaluated during the preovulation (PO), mid-luteal (ML), and late-luteal (LL) phases. Furthermore, the severity of P MDD symptoms, depressive symptoms, perceived stress, inattention, craving for sweet foods, and fatigue was assessed. The findings revealed that women with PMDD with higher levels of progesterone during the ML or LL phase or a greater increase (ML-PO) or higher sum (ML + LL) of luteal progesterone level exhibited a greater increase in PMDD symptoms during the luteal phase than did the healthy controls. Furthermore, women with PMDD exhibited higher cortisol levels during the LL phase than did the controls. The BDNF level was negatively correlated with PMDD severity. Furthermore, BDNF and VEGF levels were negatively correlated with inattention and craving for sweet foods among women with PMDD. These results suggest an association between progesterone and the exacerbation of PMDD symptoms during the LL phase. Women with PMDD have relatively high cortisol levels during the LL phase. Future investigations with experimental designs or larger sample sizes are warranted to verify the roles of progesterone and cortisol in the development of PMDD.

The role of the hypothalamic-pituitary-adrenal axis in depression across the female reproductive lifecycle: current knowledge and future directions

The aim of this narrative review is to consolidate knowledge on the role of the hypothalamic-pituitary-adrenal (HPA) axis in depression pathophysiology at different reproductive stages across the female lifespan. Despite growing evidence about the impact of gonadal hormones on mood disorders, no previous review has examined the interaction between such hormonal changes and the HPA axis within the context of depressive disorders in women. We will focus on HPA axis function in depressive disorders at different reproductive stages including the menstrual cycle (e.g., premenstrual dysphoric disorder [PMDD]), perinatally (e.g., postpartum depression), and in perimenopausal depression. Each of these reproductive stages is characterized by vast physiological changes and presents major neuroendocrine reorganization. The HPA axis is one of the main targets of such functional alterations, and with its key role in stress response, it is an etiological factor in vulnerable windows for depression across the female lifespan. We begin with an overview of the HPA axis and a brief summary of techniques for measuring HPA axis parameters. We then describe the hormonal milieu of each of these key reproductive stages, and integrate information about HPA axis function in depression across these reproductive stages, describing similarities and differences. The role of a history of stress and trauma exposure as a contributor to female depression in the context of HPA axis involvement across the reproductive stages is also presented. This review advances the pursuit of understanding common biological mechanisms across depressive disorders among women. Our overarching goal is to identify unmet needs in characterizing stress-related markers of depression in women in the context of hormonal changes across the lifespan, and to support future research in women's mental health as it pertains to pathophysiology, early diagnosis, and treatment targets.

Do contrasting socio-ecological conditions bring difference in premenstrual syndrome and its concomitants? A sedente-migrant comparative study from Eastern India

OBJECTIVES

We asked in our research whether the premenstrual syndrome (PMS) and its concomitants, differ between "sedente" and "migrant" populations hailing from the same ethnic group, owing to their living in contrasting socio-ecological conditions.

METHODS

A total of 501 Oraon adolescents (sedente: 200, migrant: 301) were studied. Data on PMS was reported retrospectively using a list of 29 standard symptoms. Principal component analysis (PCA) was applied on PMS. PCA, which resulted in six principal components (PC1 to PC6) were loaded with "behavioral and cognitive," "negative mood," "pain and fluid retention," "vestibular and breast tenderness," and "fatigue," and/or "gastrointestinal" symptoms. Step-wise hierarchical regression was applied using migration status (step 1), socio-demographic (step 2), menstrual (step 3), and nutritional and lifestyle variables (step 4) as concomitants for each principal component.

RESULTS

Significantly, a greater number of migrants reported PMS but of milder intensity, unlike the sedentes. Significant sedente-migrant differences were found in the concomitants for PMS. Multivariate analyses showed differential socio-demographic (occupational, educational and wealth status, religion), nutritional (dietary carbohydrate protein and fat, tea intake, body mass index, percent body fat, waist hip ratio, fat mass index), menstrual (age at menarche, cycle length, dysmenorrhoea) and anemic status of the sedentes and the migrants were significantly associated with PMS.

CONCLUSIONS

Sedente and migrant participants, despite hailing from the same ethnic group, sharply differed in the prevalence of PMS and its concomitants owing to their living in contrasting socio-ecological conditions.

Childhood adversity predicts stronger premenstrual mood worsening, stress appraisal and cortisol decrease in women with Premenstrual Dysphoric Disorder

Background

Lifetime traumatic events are prevalent in women with Premenstrual Dysphoric Disorder (PMDD) and predict stronger premenstrual symptom intensities. Less is known about the unique effects of childhood adversity on PMDD. This study aims to investigate the menstrual cycle related course of mood, stress appraisal and cortisol activity over time and the effects of childhood adversity - by controlling for recent stressful life events - on the cyclicity of these outcomes.

Methods

Fifty-two women with PMDD completed questionnaires on childhood adversity and stressful life events during the past 12 months. Momentary negative and positive affect, stress appraisal, and saliva-cortisol were assessed within an Ambulatory Assessment (AA) design over four consecutive days during both the follicular and the late luteal phase. This AA was repeated after five months, resulting in two measurement bursts.

Results

Women with PMDD showed expected cycle related variations in mood and stress appraisal, whereby these effects weakened over time. No cortisol cyclicity was identified. Higher childhood adversity was linked to stronger increases in negative affect and stress appraisal, and stronger decreases in positive affect from the follicular toward the late luteal phase. Women with higher childhood adversity exhibited lower cortisol levels during the late luteal phase compared to the follicular phase whereas no such cyclicity was found in women with lower childhood adversity.

Conclusion

Childhood adversity appears to show independent deteriorating effects on premenstrual mood worsening and stress appraisal in women with PMDD. The observed cortisol cyclicity in women with higher childhood adversity may point to different neuroendocrine subtypes of PMDD in relation to childhood trauma and requires further systematic research.

Psychological, physiological, and biochemical correlations after negative emotional videos in college students with and without premenstrual syndrome

Introduction

Women with premenstrual syndrome (PMS) suffer heavily from emotional problems, the pathogenesis of which is believed to be related to the hypothalamic-pituitary-adrenal (HPA) axis, autonomic nervous system (ANS) and central nervous system (CNS). We took into account all 3 aspects to observed the psychological, physiological and biochemical correlations under anger and sadness in college students with and without PMS.

Methods

33 students with PMS and 24 healthy students participated in the emotion induction experiment, and were required to fill out self-report scales. Their salivary cortisol (SCort), skin conductivity level (SCL), heart rate variability (HRV), blood pressure (BP) and electroencephalogram (EEG) data were collected at the resting stage and 10-15 minutes after each video.

Results

Compared to healthy controls, students with PMS showed lower SCort level and higher VLF at rest, and no statistic difference in activities of ANS and HPA axis after emotional videos, but different results in EEG in all conditions. The decreases in SBP during angry video, SCort after angry and neutral videos, and increases in θ band power during sad video were moderately correlated with increases in PMS score. No intergroup differences were found in self-report emotions.

Discussion

Students with PMS had lower activity of HPA axis and possibly higher activity of PNS at rest, and different response patterns in CNS in all conditions. Several EEG frequencies, especially θ band, in specific encephalic regions during emotional videos, as well as declined HPA activities in dealing with angry and neutral stressors, in which γ activity in frontal lobe may play a role, showed moderate correlations with more severe PMS.

Investigation of premenstrual syndrome in connection with physical activity, perceived stress level, and mental status-a cross-sectional study

Introduction

The premenstrual syndrome (PMS) is a critical factor in women's health, which, in addition to physical inactivity, can be influenced by the body mass index (BMI), stress, and mental state, among others. The study aimed to assess the severity of PMS symptoms among young women regarding physical inactivity, BMI, mental state, and perceived stress level.

Methods

A total of 198 female participants between the ages of 18-45 took part in a 6-month cross-sectional online questionnaire study. The average age of the participants was 25.37 ± 4.80 years. To assess physical activity, stress, mental state, and premenstrual symptoms, we employed standard questionnaires, including the International Physical Activity Questionnaire-Short Form (IPAQ-SF), the Perceived Stress Scale (PSS), the General Health Questionnaire-12 (GHQ-12), and the Premenstrual Assessment Form-Short Form (PAF-SF). The collected data were analyzed using IBM SPSS (Statistical Package for Social Sciences) version 28.0 software, with a significance level set at p < 0.05.

Results

During the analysis, we observed a significant relationship (p = 0.020) between regular exercise and the severity of PMS symptoms, as well as between mental state and PMS symptoms (p < 0.001). Furthermore, our findings revealed a significant negative correlation between regular physical activity and perceived stress levels (r = -0.179; p = 0.012), as well as between regular exercise and the participants' mental state (r = -0.157; p = 0.027). Additionally, we identified a significant difference (p < 0.001) among the six subgroups formed based on the PAF-SF and average PSS questionnaire results. Moreover, a significant difference was observed between the PAF-SF case and control groups in terms of BMI averages (p = 0.019).

Discussion

The research findings indicate that the severity of PMS symptoms is influenced by regular physical activity, mental state, and stress.

Effect of chronic unpredictable stress in female Wistar-Kyoto rats subjected to progesterone withdrawal: Relevance for Premenstrual Dysphoric Disorder neurobiology

Premenstrual Dysphoric Disorder (PMDD) is related to an abrupt drop in progesterone and impairments in the HPA axis that cause anxiety. Suffering persons report higher daily-life stress and anxiety proneness that may contribute to developing PMDD, considered a chronic stress-related disorder. Here, we explored the effect of chronic unpredictable stress (CUS) in rats subjected to progesterone withdrawal (PW) and evaluated gene expression of HPA axis activation in the stress-vulnerable Wistar-Kyoto (WKY) rat strain that is prone to anxiety. Ovariectomized WKY rats were randomly assigned to CUS or Standard-housed conditions (SHC) for 30 days. To induce PW, animals received 2 mg/kg of progesterone on day 25th for 5 days; 24 h later, they were tested using the anxiety-like burying behavior test (BBT). After behavioral completion, rats were euthanized, and brains were extracted to measure Crh (PVN) and Nr3c1 (hippocampus) mRNA. Blood corticosterone and vasopressin levels were determined. Results showed that PW exacerbated anxiety-like behaviors through passive coping in CUS-WKY. PW decreased Crh-PVN mRNA and the Nr3c1-hippocampal mRNA expression in SHC. CUS decreased Crh-PVN mRNA compared to SHC, and no further changes were observed by PW or BBT exposure. CUS reduced Nr3c1-hippocampal gene expression compared to SHC animals, and lower Nr3c1 mRNA was detected due to BBT. The PW increased corticosterone in SHC and CUS rats; however, CUS blunted corticosterone when combined with PW+BBT and similarly occurred in vasopressin concentrations. Chronic stress blunts the response of components of the HPA axis regulation when PW and BBT (systemic and psychogenic stressors, respectively) are presented. This response may facilitate less adaptive behaviors through passive coping in stress-vulnerable subjects in a preclinical model of premenstrual anxiety.

The longitudinal predictive effect of self-reported frequency of premenstrual syndrome on depression: Findings from the Australian Longitudinal Study on Women's Health

Background

Previous studies have revealed a high comorbidity between premenstrual syndrome (PMS) and depression; however, whether PMS can longitudinally predict depression has not been examined in large sample studies.

Methods

This study surveyed 8,133 women from the 1973-78 cohort of the Australian Longitudinal Study on Women's Health. Participants completed seven repeated measurements at 3-year intervals starting in 2000 (aged 22-27 years). Binary logistic and multivariate ordered logistic regression models were used to examine the predictive role of self-reported frequency of PMS symptoms in 2000 on self-reported diagnosis of depression and frequency of depressive symptoms, respectively, for each follow-up survey.

Results

Self-reported frequency of PMS symptoms in the year 2000 predicted self-reported diagnosis of depression in most follow-up surveys. Specifically, compared to women who reported "never" had PMS symptoms in 2000, those who reported "often" had them were more likely to report a diagnosis of depression in 2006 (OR = 1.72), 2012 (OR = 1.88), 2015 (OR = 1.49), and 2018 (OR = 1.90); and those who reported "sometimes" had PMS symptoms in 2000 were more likely to report a diagnosis of depression in 2012 (OR =1.37) and 2018 (OR = 1.59). Furthermore, self-reported frequency of PMS symptoms in 2000 predicted self-reported frequency of depressive symptoms in each follow-up survey. Compared to women who reported "never" had PMS symptoms in 2000, those who reported "sometimes", or "often", had PMS symptoms reported depressive symptoms more frequently.

Conclusion

Self-reported frequency of PMS can predict the self-reported frequency of depressive symptoms and the subsequent diagnosis of depression.

Factors Associated with the Prevalence and Severity of Menstrual-Related Symptoms: A Systematic Review and Meta-Analysis

This study aimed to identify factors associated with the prevalence and severity of menstrual-related symptoms. The protocol was registered in PROSPERO (CRD42021208432). We conducted literature searches of PubMed and Ichushi-Web and used the Jonna Briggs Institute critical appraisal checklist to assess the quality. Of the 77 studies included in the meta-analysis, significant odds ratios (ORs) were obtained for eight factors associated with primary dysmenorrhea (PD): age ≥ 20 years (OR: 1.18; 95% confidence interval [CI]: 1.04−1.34), body mass index (BMI) < 18.5 kg/m2 (OR: 1.51; 95% CI: 1.01−2.26), longer menstrual periods (OR: 0.16; 95% CI: 0.04−0.28), irregular menstrual cycle (OR: 1.28; 95% CI: 1.13−1.45), family history of PD (OR: 3.80; 95% CI: 2.18−6.61), stress (OR: 1.88; 95% CI: 1.30−2.72), sleeping hours < 7 h (OR: 1.19; 95% CI: 1.04−1.35), and bedtime after 23:01 (OR: 1.30; 95% CI: 1.16−1.45). Two factors were associated with severity of PD (moderate vs. severe): BMI < 18.5 kg/m2 (OR: 1.89; 95% CI: 1.01−3.54) and smoking (OR: 1.94; 95% CI: 1.08−3.47). PD severity (mild vs. severe) and prevalence of premenstrual syndrome were associated with BMI < 18.5 kg/m2 (OR: 1.91; 95% CI: 1.04−3.50) and smoking (OR: 1.86; 95% CI: 1.31−2.66), respectively. The identified risk factors could be utilized to construct an appropriate strategy to improve menstrual symptoms and support women’s health.

Effect of Aerobic Exercises in Improving Premenstrual Symptoms Among Healthy Women: A Systematic Review of Randomized Controlled Trials

Background

Premenstrual symptoms in women of reproductive age are associated with substantial distress and functional impairments. A healthy lifestyle is the first step to manage premenstrual symptoms. Recreational physical activities have been recommended as an alternative to medical management in easing premenstrual symptoms.

Objective

The objective of this systematic review is to analyze the effects of aerobic exercises in improving premenstrual symptoms among healthy women.

Methods

Randomized controlled trials (RCTs) published from inception to February 2022, were searched using keywords in electronic databases such as, SCOPUS, PubMed, PEDro, Cochrane and web of science. RCTs published in English, comparing the effects of aerobic exercise with other interventions or controls were included. PEDro scale and Cochrane collaboration tool for risk of bias was used to assess the methodological quality of included trials. Data from the included study and the participant’s characteristics, interventions, outcome and results were extracted.

Results

Five RCTs with 492 participants were included in this systematic review. Methodological quality assessed by PEDro (4.8/10) and Cochrane collaboration tool for risk of bias were moderate. Allocation concealment, blinding of participants and outcome assessors were the most common bias in all included studies. Walking, swimming and running were the common aerobic exercises performed in the RCTs. Aerobic exercise is effective in improving physical physiological symptoms among women with premenstrual syndrome (PMS).

Conclusion

Aerobic exercises are effective in improving premenstrual symptoms. This review provides moderate evidence for improving hematological parameters during PMS. Further RCTs with long term follow up and quality of life would consolidate our findings.

Altered local gyrification index and corresponding resting-state functional connectivity in individuals with high test anxiety

Previous studies have reported that test anxiety is closely related to unreasonable cognitive patterns and maladaptive emotional responses. However, its underlying brain structural and functional basis has not been thoroughly studied. This study aimed to evaluate the potential difference in local gyration index (LGI) and corresponding resting-state functional connectivity (RSFC) in individuals with high test anxiety (HTA) compared with low test anxiety (LTA). Twenty-six individuals with HTA and 28 individuals with LTA underwent T1-weighted structural and resting-state functional magnetic resonance imaging scans. Using FreeSurfer software, we contrasted the LGI between the HTA and LTA groups using a surface-based general linear model to map group contrasts on a vertex-by-vertex basis. By selecting the cortical regions with significant differences in the LGI analysis as the regions of interest, the seed-based RSFC analysis was further carried out using the Resting-State fMRI Data Analysis Toolkit to examine the differences in the functional connectivity of these cortical regions with the whole brain between the two groups. The results showed that the LGI in several cortical regions of the executive control network (ECN) and the right lateral occipital gyrus was lower in the HTA group than in the LTA group. Furthermore, compared with the LTA group, the HTA group exhibited abnormal RSFC within the ECN, between the ECN and the visual network, and between the ECN and the sensorimotor network. Our findings might provide preliminary evidence for brain morphology and functional alterations in individuals with HTA and contribute to a better understanding of the pathophysiology of TA. DATA STATEMENT: The data that support the findings of this study are available from the corresponding author upon reasonable request after completing a formal data sharing agreement.

HPA axis activity across the menstrual cycle - a systematic review and meta-analysis of longitudinal studies

Differential HPA axis function has been proposed to underlie sex-differences in mental disorders; however, the impact of fluctuating sex hormones across the menstrual cycle on HPA axis activity is still unclear. This meta-analysis investigated basal cortisol concentrations as a marker for HPA axis activity across the menstrual cycle. Through a systematic literature search of five databases, 121 longitudinal studies were included, summarizing data of 2641 healthy, cycling participants between the ages of 18 and 45. The meta-analysis showed higher cortisol concentrations in the follicular vs. luteal phase (d_SMC = 0.12, p =.004, [0.04 - 0.20]). Comparisons between more precise cycle phases were mostly insignificant, aside from higher concentrations in the menstrual vs. premenstrual phase (d_SMC = 0.17, [0.02 - 0.33], p =.03). In all included studies, nine samples used established cortisol parameters to indicate HPA axis function, specifically diurnal profiles (k = 4) and the cortisol awakening response (CAR) (k = 5). Therefore, the meta-analysis highlights the need for more rigorous investigation of HPA axis activity and menstrual cycle phase.

Anxiety-like Behavior and GABAAR/BDZ Binding Site Response to Progesterone Withdrawal in a Stress-Vulnerable Strain, the Wistar Kyoto Rats

Stress susceptibility could play a role in developing premenstrual anxiety due to abnormalities in the hypothalamus–pituitary–adrenal (HPA) axis and impairments in the GABAA receptors’ benzodiazepine (BDZ) site. Hence, we studied the stress-vulnerable Wistar Kyoto rat strain (WKY) to evaluate progesterone withdrawal (PW) effects on anxiety, HPA axis response, and to explore indicators of GABAA functionality in the BDZ site. For five days, ovariectomized WKY rats were administered 2.0 mg/kg of progesterone. Twenty-four hours after the last administration, rats were tested in the anxiety-like burying behavior test (BBT) or elevated plus maze test (EPM), and corticosterone was determined. [3H]Flunitrazepam binding autoradiography served as the BDZ binding site index of the GABAA receptor in amygdala nuclei and hippocampus’s dentate gyrus (DG). Finally, different doses of diazepam in PW-WKY rats were tested in the BBT. PW induced anxiety-like behaviors in both BBT and EPM compared with No-PW rats. PW increased corticosterone, but was blunted when combined with PW and BBT. PW increased [3H]Flunitrazepam binding in the DG and central amygdala compared with No-PW rats. Diazepam at a low dose induced an anxiogenic-like response in PW rats, suggesting a paradoxical response to benzodiazepines. Overall, PW induced anxiety-like behavior, a blunted HPA axis response, and higher GABAAR/BZD binding site sensitivity in a stress-vulnerable rat strain. These findings demonstrate the role of stress-susceptibility in GABAAR functionality in a preclinical approximation of PMDD.

Daily cortisol awakening response and menstrual symptoms in young females

Menstrual symptoms include some rhythmical changes and stress perception but women differ in duration and severity of these symptoms. It is not known whether these differences are associated with cortisol awakening response (CAR). The aim of the current study was to follow young women daily for the CAR and menstrual parameters throughout the whole menstrual cycle. Healthy and regularly cycling young women (n = 16, 17 to 31-year-old) participated in the current study. The daily records of severity of problems (DRSP) was filled in daily by the participants. CAR was also assessed daily form the salivary samples collected at a 0-, 15-, 30- and 60-min post-awakening. In terms of daily awakening cortisol profiles, women had either 2-20 (n = 3), or 20-200 (n = 8) or 200-2000 (n = 5) ng/ml cortisol according to the median levels throughout their cycle. CAR was weakly and negatively correlated with DRSP scores but strongly and positively with oestradiol (R²  = 0.300; p = 0.000) and progesterone (R²  = 0.490; p = 0.000) concentrations. Individuals with higher oestradiol and progesterone concentrations did not have high DRSP scores. In conclusion, CAR had a very high between-subject difference but had a low within-subject difference throughout the days of menstrual cycle, suggesting that CAR is a relatively stable personal trait. Moreover, the interplay between cortisol, progesterone and oestradiol appears to be important for the severity of menstrual symptoms.

Melatonin for premenstrual syndrome: A potential remedy but not ready

Premenstrual syndrome (PMS), a recurrent and moderate disorder that occurs during the luteal phase of the menstrual cycle and quickly resolves after menstruation, is characterized by somatic and emotional discomfort that can be severe enough to impair daily activities. Current therapeutic drugs for PMS such as selective serotonin reuptake inhibitors are not very satisfying. As a critical pineal hormone, melatonin has increasingly been suggested to modulate PMS symptoms. In this review, we update the latest progress on PMS-induced sleep disturbance, mood changes, and cognitive impairment and provide possible pathways by which melatonin attenuates these symptoms. Moreover, we focus on the role of melatonin in PMS molecular mechanisms. Herein, we show that melatonin can regulate ovarian estrogen and progesterone, of which cyclic fluctuations contribute to PMS pathogenesis. Melatonin also modulates gamma-aminobutyric acid and the brain-derived neurotrophic factor system in PMS. Interpreting the role of melatonin in PMS is not only informative to clarify PMS etiology but also instructive to melatonin and its receptor agonist application to promote female health. As a safe interaction, melatonin treatment can be effective in alleviating symptoms of PMS. However, symptoms such as sleep disturbance, depressive mood, cognitive impairment are not specific and can be easily misdiagnosed. Connections between melatonin receptor, ovarian steroid dysfunction, and PMS are not consistent among past studies. Before final conclusions are drawn, more well-organized and rigorous studies are recommended.

Steroid stress hormone changes throughout the menstrual cycle: A rise in evening aldosterone concentration in early luteal phase precedes the symptoms of premenstrual syndrome

There is still a lack of consistent evidence on dysregulation of steroid stress hormones cortisol and aldosterone in premenstrual syndrome (PMS). We aimed to test the hypothesis that, in healthy women, salivary aldosterone concentrations are higher in those with PMS compared to controls, particularly during the luteal phase of the menstrual cycle. In total, 99 female subjects (49 women with and 50 women without PMS) participated in a prospective non-interventional case-control study. Saliva sampling was performed in the follicular (day 8), early luteal (day 20) and late luteal phase (2 days before expected onset of bleeding) of the menstrual cycle in the morning and the evening. The results confirmed the hypothesis that salivary aldosterone concentrations are higher in women with PMS during the early luteal phase compared to controls (p < .01) in the evening. Early luteal phase aldosterone concentrations positively correlated with the frequency of premenstrual symptoms. Women with PMS exhibited a flatter morning to evening aldosterone slope compared to controls (p < .05). Morning and evening salivary cortisol concentrations were unchanged throughout the menstrual cycle in both groups of women. In conclusion, evening salivary aldosterone, but not cortisol concentrations, are increased in women with PMS during the early luteal phase compared to controls. Cortisol does not appear to be involved in the mechanisms contributing to the course of PMS. High evening salivary aldosterone in the early luteal phase may represent an important risk factor and could be of predictive value for the occurrence of premenstrual symptoms.

The Specificities of Elite Female Athletes: A Multidisciplinary Approach

Female athletes have garnered considerable attention in the last few years as more and more women participate in sports events. However, despite the well-known repercussions of female sex hormones, few studies have investigated the specificities of elite female athletes. In this review, we present the current but still limited data on how normal menstrual phases, altered menstrual phases, and hormonal contraception affect both physical and cognitive performances in these elite athletes. To examine the implicated mechanisms, as well as the potential performances and health risks in this population, we then take a broader multidisciplinary approach and report on the causal/reciprocal relationships between hormonal status and mental and physical health in young (18-40 years) healthy females, both trained and untrained. We thus cover the research on both physiological and psychological variables, as well as on the Athlete Biological Passport used for anti-doping purposes. We consider the fairly frequent discrepancies and summarize the current knowledge in this new field of interest. Last, we conclude with some practical guidelines for eliciting improvements in physical and cognitive performance while minimizing the health risks for female athletes.

Effects of PMS50 supplementation on psychological symptoms of students with premenstrual syndrome

OBJECTIVE

To evaluate the effects of PMS50 supplementation on psychological symptoms in university students in Iran.

METHODS

This double-blind clinical trial was conducted at Ahvaz Jundishapur University of Medical Sciences, between December 2018 and March 2019. Fifty female students with moderate to severe premenstrual syndrome (PMS) randomly received either 550 mg/day of PMS50 (n = 25) or placebo (n = 25), starting from 1 week before till the end of menstruation for three consecutive menstrual cycles. Anthropometric indices, dietary intake, physical activity level, and severity of PMS were assessed at baseline and post-intervention. Data were analyzed by SPSS (version 22). Independent t test was used to compare the results between groups. Paired t test was used to compare the results within groups before and after study.

RESULTS

There was a significant improvement in psychological symptoms including depression, anger, feeling of hopelessness, desire to be alone, mood swings, irritability, anxiety, and poor concentration observed in the intervention group compared with the control group post-intervention. Restlessness was significantly reduced in both groups post-intervention. The mean scores of low self-esteem, change in appetite, and food cravings were decreased in both groups, but not significant between groups.

CONCLUSION

PMS50 supplementation may be effective in improvement of psychological symptoms in PMS. Clinical Trial Registration No.: IRCT20181218042038 N1.

Short report: cognitive behavioral therapy - a primary mode for premenstrual syndrome management: systematic literature review

Most women in reproductive age experience at least one premenstrual syndrome (PMS) symptom every month over many years, and about 5% experience significant impairment, requiring professional intervention. Offering effective and sustainable treatment, is essential. While research acknowledges the effectiveness of nonpharmacological methods, cognitive behavioral therapy (CBT) and lifestyle modifications, as a treatment alternative, selective serotonin reuptake inhibitors or hormonal ovulation suppression continue to be recommended as a first-line treatment. We hypothesize that nonpharmacological methods will be sufficient for effective and sustainable PMS management. A systematic literature review was conducted for peer-reviewed original studies with the search terms: CBT, psychoeducation, PMS and premenstrual dysphoric disorder. All 32 identified studies found a significant reduction in PMS to complete remission with nonpharmacological interventions. No side effects were reported, and positive effect was sustained over time. Psychoeducational self-help packages, delivered with the affordance of modern technology, appeared to be enough for most women to manage successfully their PMS distress. Most severe PMS forms required one-to-one CBT. Nonpharmacological methods can be recommended as the primary mode for PMS management. More high-quality research is required, for developing personalized self-help packages, as well as the full use of modern technology for delivering the service.

Reduced Reward Responsiveness in Women With Moderate - to - Severe Premenstrual Syndrome: Evidence From a Probabilistic Reward Task

Nearly 50% of women of reproductive age worldwide experience premenstrual syndrome (PMS). Women with PMS exhibit low positive affect and low frontal electroencephalography asymmetry scores, both of which are associated with reward processing. These findings suggest that women with PMS may exhibit deficiencies in reward processing. A probabilistic reward task based on signal detection approach was used to assess reward responsiveness in 30 women with moderate-to-severe PMS and 31 controls without PMS. The results revealed that in the late luteal phase, the women with moderate-to-severe PMS exhibited lower response bias and lower hit rate toward more frequently rewarded stimuli (rich stimuli) than the controls. By contrast, the response bias and hit rate did not differ between the two groups in the follicular phase. The group differences still remained after controlling for anhedonic symptoms. Furthermore, trial-by-trial probability analyses revealed that women with moderate-to-severe PMS exhibited a trend of having a higher miss rate for rich stimuli than the controls. In particular, when a rich stimulus was preceded by an infrequently rewarded stimulus (a rewarded lean stimulus), participants in the PMS group exhibited a trend for higher miss rate than those in the control group in the late luteal and follicular phases. However, group differences in the probability analyses were nonsignificant after controlling for anhedonic symptoms. These results provide preliminary evidence that women with moderate-to-severe PMS exhibit dysfunctional reward responsiveness and impaired ability to modulate their behavior as a function of prior reinforcement.
