Selective serotonin reuptake inhibitors for premenstrual syndrome and premenstrual dysphoric disorder.

BACKGROUND: Premenstrual syndrome (PMS) is a combination of physical, psychological and social symptoms in women of reproductive age, and premenstrual dysphoric disorder (PMDD) is a severe type of the syndrome, previously known as late luteal phase dysphoric disorder (LLPDD). Both syndromes cause symptoms during the two weeks leading up to menstruation (the luteal phase). Selective serotonin reuptake inhibitors (SSRIs) are increasingly used as a treatment for PMS and PMDD, either administered in the luteal phase or continuously. We undertook a systematic review to assess the evidence of the positive effects and the harms of SSRIs in the management of PMS and PMDD. OBJECTIVES: To evaluate the benefits and harms of SSRIs in treating women diagnosed with PMS and PMDD. SEARCH METHODS: We searched the Cochrane Gynaecology and Fertility (CGF) Specialised Register of Controlled Trials, CENTRAL, MEDLINE, Embase and PsycINFO for randomised controlled trials (RCTs) in November 2023. We checked reference lists of relevant studies, searched trial registers and contacted experts in the field for any additional trials. This is an update of a review last published in 2013. SELECTION CRITERIA: We considered studies in which women with a prospective diagnosis of PMS, PMDD or LLPDD were randomised to receive SSRIs or placebo. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods. We pooled data using a random-effects model. We calculated standardised mean differences (SMDs) with 95% confidence intervals (CIs) for premenstrual symptom scores, using 'post-treatment' scores for continuous data. We calculated odds ratios (ORs) with 95% CIs for dichotomous outcomes. We stratified analyses by type of administration (luteal phase or continuous). We calculated absolute risks and the number of women who would need to be taking SSRIs in order to cause one additional adverse event (i.e. the number needed to treat for an additional harmful outcome (NNTH)). We rated the overall certainty of the evidence for the main findings using GRADE. MAIN RESULTS: We included 34 RCTs in the review. The studies compared SSRIs (i.e. fluoxetine, paroxetine, sertraline, escitalopram and citalopram) to placebo. SSRIs probably reduce overall self-rated premenstrual symptoms in women with PMS and PMDD (SMD -0.57, 95% CI -0.72 to -0.42; I2 = 51%; 12 studies, 1742 participants; moderate-certainty evidence). SSRI treatment was probably more effective when administered continuously than when administered only in the luteal phase (P = 0.03 for subgroup difference; luteal phase group: SMD -0.39, 95% CI -0.58 to -0.21; 6 studies, 687 participants; moderate-certainty evidence; continuous group: SMD -0.69, 95% CI -0.88 to -0.51; 7 studies, 1055 participants; moderate-certainty evidence). The adverse effects associated with SSRIs were nausea (OR 3.30, 95% CI 2.58 to 4.21; I2 = 0%; 18 studies, 3664 women), insomnia (OR 1.99, 95% CI 1.51 to 2.63; I2 = 0%; 18 studies, 3722 women), sexual dysfunction or decreased libido (OR 2.32, 95% CI 1.57 to 3.42; I2 = 0%; 14 studies, 2781 women), fatigue or sedation (OR 1.52, 95% CI 1.05 to 2.20; I2 = 0%; 10 studies, 1230 women), dizziness or vertigo (OR 1.96, 95% CI 1.36 to 2.83; I2 = 0%; 13 studies, 2633 women), tremor (OR 5.38, 95% CI 2.20 to 13.16; I2 = 0%; 4 studies, 1352 women), somnolence and decreased concentration (OR 3.26, 95% CI 2.01 to 5.30; I2 = 0%; 8 studies, 2050 women), sweating (OR 2.17, 95% CI 1.36 to 3.47; I2 = 0%; 10 studies, 2304 women), dry mouth (OR 2.70, 95% CI 1.75 to 4.17; I2 = 0%; 11 studies, 1753 women), asthenia or decreased energy (OR 3.28, 95% CI 2.16 to 4.98; I2 = 0%; 7 studies, 1704 women), diarrhoea (OR 2.06, 95% CI 1.37 to 3.08; I2 = 0%; 12 studies, 2681 women), and constipation (OR 2.39, 95% CI 1.09 to 5.26; I2 = 0%; 7 studies, 1022 women). There was moderate-certainty evidence for all adverse effects other than somnolence/decreased concentration, which was low-certainty evidence. Overall, the certainty of the evidence was moderate. The main weakness was poor reporting of study methodology. Heterogeneity was low or absent for most outcomes, although there was moderate heterogeneity in the analysis of overall self-rated premenstrual symptoms. Based on the meta-analysis of response rate (the outcome with the most included studies), there was suspected publication bias. In total, 68% of the included studies were funded by pharmaceutical companies. This stresses the importance of interpreting the review findings with caution. AUTHORS' CONCLUSIONS: SSRIs probably reduce premenstrual symptoms in women with PMS and PMDD and are probably more effective when taken continuously compared to luteal phase administration. SSRI treatment probably increases the risk of adverse events, with the most common being nausea, asthenia and somnolence.

Associations of luteal phase changes in vagally mediated heart rate variability with premenstrual emotional changes.

BACKGROUND: A recent meta-analysis revealed that vagally mediated heart rate variability (vmHRV; a biomarker of emotion regulation capacity) significantly decreases in the luteal phase of the menstrual cycle. As two follow-up studies suggest, these vmHRV decreases are driven primarily by increased luteal progesterone (P4). However, analyses also revealed significant interindividual differences in vmHRV reactivity to the cycle, which is in line with longstanding evidence for interindividual differences in mood sensitivity to the cycle. The present study begins to investigate whether these interindividual differences in vmHRV cyclicity can explain who is at higher risk of showing premenstrual emotional changes. We expected a greater degree of midluteal vmHRV decrease to be predictive of a greater premenstrual increase in negative affect. METHODS: We conducted an observational study with a naturally cycling community sample (N = 31, M = 26.03 years). Over a span of six weeks, participants completed (a) daily ratings of negative affect and (b) counterbalanced lab visits in their ovulatory, midluteal, and perimenstrual phases. Lab visits were scheduled based on positive ovulation tests and included assessments of baseline vmHRV and salivary ovarian steroid levels. RESULTS: In line with previous research, multilevel models suggest that most of the sample shows ovulatory-to-midluteal vmHRV decreases which, however, were not associated with premenstrual emotional changes. Interestingly, it was only the subgroup with luteal increases in vmHRV whose negative affect markedly worsened premenstrually and improved postmenstrually. CONCLUSION: The present study begins to investigate cyclical changes in vmHRV as a potential biomarker of mood sensitivity to the menstrual cycle. The results demonstrate a higher level of complexity in these associations than initially expected, given that only atypical midluteal increases in vmHRV are associated with greater premenstrual negative affect. Potential underlying mechanisms are discussed, among those the possibility that luteal vmHRV increases index compensatory efforts to regulate emotion in those with greater premenstrual negative affect. However, future studies with larger and clinical samples and more granular vmHRV assessments should build on these findings and further explore associations between vmHRV cyclicity and menstrually related mood changes.

[Establishment and evaluation of a premenstrual syndrome rat model induced by progesterone-withdrawal and emotional-stimulation].

Premenstrual syndrome(PMS) lacks a highly consistent and feasible animal model that aligns with diagnostic and therapeutic standards in both traditional Chinese medicine(TCM) and western medicine, resulting in a lack of reliable experimental carriers for studying its pathogenesis and pharmacological effects. This study aims to systematically analyze the biological implications of PMS from the perspective of the "disease-syndrome-symptom" correlation and establish preparation and evaluation methods for an improved animal model of this disease. Firstly, clinical symptom gene sets related to the Qi stagnation syndromes due to liver depression and blood stasis in PMS in both modern medicine and TCM diagnostic standards were collected through GeneCards, DisGeNET, Mala-Cards, and the System of Foundational Diagnostic Association(SoFDA) database, as well as published literature. Based on the interaction information between genes, a "disease-syndrome-symptom" correlation network of PMS was established. Based on data mining results, an improved rat model of PMS was prepared by combining chronic restraint stress with the classical progesterone-withdrawal mo-del to simulate emotional depression caused by external environmental stimuli during the clinical onset process, inducing pathological damage from both physiological and emotional dimensions. The evaluation of the improved model before and after modification included open field experiment scores, organ indices, ovarian pathological changes, serum levels of estradiol(E_2), follicle-stimulating hormone/luteinizing hormone(FSH/LH), 5-hydroxytryptamine(5-HT), dopamine(DA), norepinephrine(NE), as well as coagulation parameters and hemorheology indexes. By calculating the degree, betweenness, and closeness centrality of nodes in the "disease-syndrome-symptom" correlation network, 163 core genes with topological importance were identified. Further biological function mining results indicated that core genes in PMS mainly participated in the regulation of the "nervous-endocrine-immune" system and pathways related to circulatory disorders. Mapping analysis of clinical phenotype symptom gene sets suggested significant correlations between core genes in PMS and depressive symptoms and pain symptoms caused by blood stasis. Compared with the simple progesterone withdrawal model, rats subjected to combined injections and restraint stress showed more significant abnormalities in open field experiment scores, ovarian tissue pathology, serum neurotransmitter levels of 5-HT and DA, as well as serum hormone levels of E_2 and FSH/LH. The modified modeling conditions exacerbated the pathological changes in blood rheology, coagulation function, and red blood cell morphology in model rats, confirming that the improved rat model could characterize the "nervous-endocrine-immune" system disorder and circulatory system disorders in the occurrence and progression of PMS, consistent with the clinical diagnostic and therapeutic standards of both TCM and western medicine. The establishment of the improved rat model of PMS can provide a reliable experimental carrier for elucidating the pathogenesis of PMS and discovering and evaluating therapeutic drugs. It also provides references for objectively reflecting the clinical characteristics of PMS in TCM and western medicine and precision treatment.

Emotion-focused therapy for women with premenstrual dysphoric disorder: a randomized clinical controlled trial.

BACKGROUND: Premenstrual dysphoric disorder (PMDD) is a debilitating condition, affecting women of reproductive age. It is characterized by severe periodic physical and psychological symptoms, which end after the onset of menstruation. This study aimed to evaluate the effectiveness of emotion-focused therapy (EFT) for PMDD patients. METHODS: A total of 48 PMDD women, in the age range of 18-44 years, were randomly assigned to two intervention and control groups. The intervention group participated in 16 weeks of EFT treatment, while the control group was selected based on the waiting list (waitlist control group) and followed-up after three months. Forty-four patients finally completed this study. The participants completed the Premenstrual Syndrome Screening Tool (PSST), Difficulties in Emotion Regulation Scale (DERS), and Depression Anxiety Stress Scale-21 (DASS-21) in the first premenstrual period before treatment, the first premenstrual period after treatment, and the premenstrual period three months after treatment. RESULTS: Based on the repeated measure analysis of variances, the total score of DERS and the total score of PSST decreased significantly (P < 0.05). Also, in DASS-21, the scores of depression and stress subscales reduced significantly (P < 0.05), while there was no significant decrease in the score of anxiety subscale (P > 0.05). CONCLUSION: Based on the present results, EFT can be an effective treatment for alleviating the symptoms of PMDD. This treatment can reduce the emotion regulation difficulties of women with PMDD and alleviate the symptoms of depression and stress.

Mental health and quality of life in patients with premenstrual exacerbation: a cross-sectional study in Japan.

BACKGROUND: In the classification of premenstrual disorders (PMDs), premenstrual exacerbation (PME) is listed as one of the variants of PMDs, along with core PMD. However, the incidence of PME and its impact on mental health and quality of life have not been investigated. Therefore, we investigated the proportion of PME among women seeking treatment for premenstrual symptoms in Japan and compared the levels of anxiety, depression and quality of life between women with PME and those with core PMD. METHODS: Women who presented to the Department of Obstetrics and Gynaecology of a single institute for treatment of premenstrual symptoms and were diagnosed with PMDs using patient diaries were included in the study. Based on the diagnosis, patients were divided into two groups (core PMD and PME) and their responses to a questionnaire on mental health and quality of life at the first visit were analysed. RESULTS: A total of 32 women were diagnosed with PMDs (22 with core PMD and 10 with PME). All underlying medical conditions in women with PME were psychiatric disorders. There were no significant differences in various factors between the two groups. In terms of mental health, the PME group had higher levels of anxiety and depression than the core PMD group. Regarding quality of life, the PME group had lower scores than the core PMD group in all domains except physical and social functioning. CONCLUSIONS: Patients seeking treatment for premenstrual symptoms included many PME. Women with PME were more anxious and depressed than those with core PMD, and their quality of life was low in both physical and psychological domains. Patients with PME should be diagnosed and treated more appropriately.

Premenstrual exacerbation of underlying medical conditions is one of the variants of premenstrual disorders. This study aimed to assess the proportion of premenstrual exacerbation among patients attending a gynaecological clinic for premenstrual symptoms and to evaluate their mental health and quality of life. Women diagnosed with premenstrual disorder were divided into the core premenstrual disorder group and the premenstrual exacerbation group. We compared the mental health and quality of life scores calculated from the questionnaire between the two groups. Among the patients diagnosed with premenstrual disorders, about one-third were patients with premenstrual exacerbation. The premenstrual exacerbation group were more anxious and depressed than the core premenstrual disorder group, and had lower quality of life scores in almost all domains. The results underscore the importance that health care providers should always consider the possibility of premenstrual exacerbation when managing patients with premenstrual symptoms and provide appropriate care for these patients.

The association of the severity of Omicron with menstrual and premenstrual syndrome among reproductive age women in China: a cross-sectional study.

This study aimed to investigate changes in menstruation and the association of the severity of Omicron with menstruation after the nationwide outbreak of COVID-19 in China. A cross-sectional study adopted an electronic questionnaire to conduct an anonymous online survey. The survey targeted women of reproductive age who had been infected with SARS-CoV-2, and were menstruating regularly in the six months prior to the infection, and experienced at least one menstrual cycle after the infection. The 737 included participants were divided into mild and severe groups based on the severity of the infection. Deviations in first menstrual cycle post-infection were reported in 46.4% of participants (mild group 40.1% vs. severe group 55.2%, P<0.05). Menstrual changes were predominantly a late menstrual period (mild group 25.3% vs. severe group 30.4%), a shorter duration of menstrual flow (mild group 10.4% vs. severe group 14.7%), and a decrease in menstrual flow volume (mild group 16% vs. severe group 21.6%). Premenstrual syndrome symptoms in a small number of women were worse compared with pre-infection, especially in the severe group. During the second menstrual period after infection, most participants reported their menstrual characteristics had returned to those of pre-infection (mild group 88% vs. severe group 80.2%, P<0.05). In this investigation, SARS-CoV-2 infection had a substantial effect on women's menstrual characteristics, and the changes were mostly transient. Women with more severe COVID-19 symptoms experienced more significant changes. The potential long-term effects of SARS-CoV-2 on female reproductive health require further observation and research.

Cette étude visait à étudier les changements dans la menstruation et l'association entre la gravité d'Omicron et la menstruation après l'épidémie nationale de COVID-19 en Chine. Une étude transversale a adopté un questionnaire électronique pour mener une enquête anonyme en ligne. L'enquête visait les femmes en âge de procréer qui avaient été infectées par le SRAS-CoV-2, qui avaient leurs règles régulièrement au cours des six mois précédant l'infection et qui ont connu au moins un cycle menstruel après l'infection. Les 737 participants inclus ont été divisés en groupes légers et sévères en fonction de la gravité de l'infection. Des écarts dans le premier cycle menstruel post-infection ont été signalés chez 46,4 % des participantes (groupe léger 40,1 % contre groupe sévère 55,2 %, P <0,05). Les changements menstruels étaient principalement une période menstruelle tardive (groupe léger 25,3 % contre groupe sévère 30,4 %), une durée plus courte du flux menstruel (groupe léger 10,4 % contre groupe sévère 14,7 %) et une diminution du volume du flux menstruel (groupe léger). 16 % contre groupe sévère 21,6 %). Les symptômes du syndrome prémenstruel chez un petit nombre de femmes étaient pires que ceux observés avant l'infection, en particulier dans le groupe sévère. Au cours de la deuxième période menstruelle après l'infection, la plupart des participantes ont déclaré que leurs caractéristiques menstruelles étaient revenues à celles d'avant l'infection (groupe léger 88 % contre groupe sévère 80,2 %, P <0,05). Dans cette enquête, l'infection par le SRAS-CoV-2 a eu un effet substantiel sur les caractéristiques menstruelles des femmes, et les changements ont été pour la plupart transitoires. Les femmes présentant des symptômes plus graves de la COVID-19 ont connu des changements plus importants. Les effets potentiels à long terme du SRAS-CoV-2 sur la santé reproductive des femmes nécessitent des observations et des recherches plus approfondies.

Effect of dairy products fortified with vitamin d3 on restless legs syndrome in women with premenstrual syndrome, abdominal obesity and vitamin d deficiency: a pilot study.

BACKGROUNDS: Restless legs syndrome (RLS) is an unpleasant condition that affects the quality of life of patients. Its prevalence in increased in women with premenstrual syndrome (PMS). Vitamin D plays a key role in female reproduction through its impact on calcium homeostasis and neurotransmitters. We aimed to evaluate the effect of dairy products fortified with Vitamin D3 on RLS in women with PMS. MATERIALS AND METHODS: We conducted a 2.5-month, randomized, total-blinded clinical trial to evaluate the effectiveness of low-fat milk and yogurt fortified with vitamin D on RLS in women with PMS. Among 141 middle-aged women with abdominal obesity, 71 and 70 cases received fortified and non-fortified low-fat dairy products, respectively. All subjects completed a Symptoms Screening Tool (PSST) and RLS questionnaires. RESULTS: The results showed that in the women with severe PMS (PSST > 28), serum levels of vitamin D increased significantly following vitamin D fortification. The mean restless legs score in the severe PMS subgroup (PSST > 28) was significantly lower after the intervention (p < 0.05. Serum Vitamin D levels significantly differed between intervention and control groups in all individuals (PSST < 19, PSST 19-28, and PSST > 28) (p < 0.05), but no significant differences were found between RLS scores of the intervention and control groups in the three PMS subgroups (p > 0.05). CONCLUSION: Fortifying dairy products with vitamin D3 can increase the serum levels of vitamin D and reduce the RLS severity in women with severe PMS, but not in other groups.

Effect of progressive muscle relaxation exercises on symptoms of premenstrual syndrome: A single-blind randomized controlled trial.

AIM: This study was carried out to determine the effect of progressive muscle relaxation exercises (PMR) on premenstrual syndrome (PMS) symptoms. METHODS: The study was designed in a single-blind randomized controlled type. The study was conducted in a hospital in Western Türkiye. Seventy-nine single women who experienced PMS who met the inclusion criteria were randomly assigned to the experimental group in which PMR would be applied, and the control group to continue their routine coping habits regarding PMS. PMR were applied to the experimental group every day for 8 weeks. At the end of 8 weeks, the experimental and control groups were re-evaluated with the Premenstrual Syndrome Scale (PMSS). RESULTS: At the beginning of the study, it was observed that the individual, health characteristics and PMSS mean scores of the women in the experimental and control groups were similar (p > 0.05). At the end of eight weeks, it was seen that the mean PMSS score of the experimental group was lower than that of the control group, and the difference was statistically significant (p < 0.001). When in-group comparisons were made at the end of the exercise program, no significant difference was found in the mean PMSS score of the control group compared to the beginning (p > 0.05). The PMSS score of the experimental group decreased significantly and the difference was statistically significant (p < 0.001). CONCLUSION: In this study, it was seen that PMR were effective in improving PMS.

Severity of premenstrual symptoms among women with musculoskeletal pain: relation to vitamin D, calcium, and psychological symptoms.

Premenstrual syndrome (PMS) has various symptoms that occur during the luteal phase of the menstrual cycle and subside after menstruation. Anxiety and depression are prevalent in women with PMS and may exacerbate the severity of PMS. Vitamin D and calcium deficiency may have a role in developing anxiety, depression, and musculoskeletal pain (MSP). The aim of this study was to evaluate selected premenstrual symptoms in relation to serum vitamin D levels, daily calcium consumption, and psychological symptoms among women with MSP. The study population consisted of 108 women with MSP and 108 healthy controls. Information about premenstrual symptoms and calcium consumption were collected. Psychological symptoms were assessed using the Hospital Anxiety and Depression Scale (HADS). Vitamin D was determined by electrochemiluminescence immunoassay. Women with MSP had lower serum vitamin D levels, lower daily calcium consumption, higher HADS scores for anxiety and depression, and higher frequency of severe premenstrual symptoms including fatigue, headache, irritability, mood swings, anxiety, depression, and social withdrawal compared to controls (P < 0.01). Abnormal HADS scores for anxiety and depression were associated with increased severity of premenstrual symptoms (P < 0.05). Deficient vitamin D and calcium consumption were associated with abnormal HADS scores for anxiety and depression (P < 0.05) and with increased severity of premenstrual headache, irritability, anxiety, and depression (P < 0.05). Low calcium consumption was associated with increased severity of premenstrual irritability, anxiety, depression, and social withdrawal (P < 0.05). The results suggest that vitamin D deficiency, low calcium consumption, psychological symptoms, and MSP could be interrelated and implicated in the etiology severe premenstrual symptoms. Further studies are necessary to assess whether vitamin D and calcium supplements can relieve MSP and premenstrual symptoms.

Prevalence of premenstrual syndrome in adolescent girls.

BACKGROUND: Premenstrual syndrome (PMS) is characterized by physical, cognitive, emotional, and behavioral symptoms that appear during the luteal phase of the menstrual cycle, disappear after menstruation, and are recurrent in every cycle. PMS significantly affects the social and academic lives of adolescents, and historically, it has been neglected by healthcare professionals. We aimed to evaluate the current point prevalence of PMS in Turkish adolescents presented to a tertiary adolescent medicine clinic. MATERIAL AND METHOD: Adolescent girls between the ages of 12 and 18 and who had regular menstrual cycles for at least three months without any mental or chronic illness were assessed. A clinic information form and the 'Premenstrual Syndrome Scale' (PMSS) questionnaire were completed. Those with a PMSS total score of more than 50% of the total score (>110 out of 220) were classified as PMS (+). Those classified as PMS were further classified as mild-moderate (score: 110-150) and severe (>150). RESULTS: The study included 417 adolescents. The point prevalence of PMS was found to be 61.2% (n:255). Of those with PMS, 49.4% had mild-moderate and 50.6% had severe PMS. The mean PMSS score was 154.56 ± 30.43 in the PMS group and 76.17 ± 20.65 in the non-PMS group (p<0.001). The mean age was 15.41 ± 1.3 years in the PMS group and 14.88 ± 1.35 years in the non-PMS group (p=0.029). None of the youth in our study applied to our clinic due to any premenstrual complaints. CONCLUSION: PMS is frequently observed in youth, as indicated by our study. Adolescents have little awareness of PMS and their need for healthcare services. During the evaluation of adolescents, it is important for health care providers to acquire knowledge regarding the features of menstrual cycles and conduct a comprehensive psychosocial assessment.

Symptoms of premenstrual dysphoric disorder and cycle phase are associated with enhanced facial emotion detection: An online cross-sectional study.

BACKGROUND: Premenstrual dysphoric disorder is a depressive disorder affecting 5%-8% of people with menstrual cycles. Despite evidence that facial emotion detection is altered in depressive disorders, with enhanced detection of negative emotions (negativity bias), minimal research exists on premenstrual dysphoric disorder. OBJECTIVES: The goal of this study was to investigate the effect of premenstrual dysphoric disorder symptoms and the premenstrual phase on accuracy and intensity at detection of facial emotions. DESIGN: Cross-sectional quasi-experimental design. METHOD: The Facial Emotion Detection Task was administered to 72 individuals assigned female at birth with no premenstrual dysphoric disorder (n = 30), and provisional PMDD (n = 42), based on a retrospective Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition-based measure of premenstrual dysphoric disorder. Facial emotion detection was examined both irrespective of menstrual cycle phase, and as a function of premenstrual phase (yes, no). The task used neutral-to-emotional facial expression morphs (15 images/morph). Participants indicated the emotion detected for each image within the progressive intensity morph. For all six basic emotions (sad, angry, fearful, happy, disgust, and surprise), two scores were calculated: accuracy of responses and the intensity within the morph at which the correct emotion was first detected (image number). RESULTS: Individuals reporting moderate/severe symptoms of premenstrual dysphoric disorder had more accurate and earlier detection of disgust, regardless of cycle phase. In addition, those with provisional premenstrual dysphoric disorder detected sad emotions earlier. A premenstrual dysphoric disorder group × cycle phase interaction also emerged: individuals reporting premenstrual dysphoric disorder symptoms were more accurate at detecting facial emotions during the premenstrual phase compared to the rest of the cycle, with a large effect size for sad emotions. CONCLUSION: The findings suggest enhanced facial emotion processing in individuals reporting symptoms of premenstrual dysphoric disorder, particularly for sadness and disgust. However, replication is required with larger samples and prospective designs. This premenstrual dysphoric disorder premenstrual emotion detection advantage suggests an adaptive cognitive mechanism in premenstrual syndrome/premenstrual dysphoric disorder, and challenges stigma surrounding premenstrual experiences.

Women with Severe Premenstrual Syndrome or Probable Premenstrual Dysphoric Disorder are Better at Identifying Emotional Expressions on People's Faces, Especially During the Premenstrual PhasePremenstrual dysphoric disorder is a depressive disorder affecting women where they experience emotional and physical symptoms during the premenstrual phase (i.e. the week before one's period). It is a severe form of premenstrual syndrome. Research indicates that depression can affect facial emotion recognition. Accurately recognizing other people's emotions is an important skill that helps us develop social connections and keep ourselves and others safe. Quick recognition of facial emotions allows us to understand and support others, and quickly identify dangerous situations by recognizing other people's emotional responses. The goal of this study was to examine how premenstrual dysphoric disorder symptoms and the premenstrual phase may affect the ability of women to recognize and identify emotions on other people's faces. A total of 72 women (42 with premenstrual dysphoric disorder, 30 without premenstrual dysphoric disorder) completed the Facial Emotion Detection Task. This task measured how accurate and early the women were able to detect happiness, sadness, anger, fear, surprise, and disgust in faces. Women with moderate/severe symptoms of premenstrual dysphoric disorder had more accurate and earlier detection of disgust, regardless of where they were in their menstrual cycle. Women with premenstrual dysphoric disorder detected sad emotions earlier. Furthermore, women with premenstrual dysphoric disorder were more accurate at detecting facial emotions when they were tested in the premenstrual phase, and were especially more accurate in detecting sad emotions. The findings suggest that women with premenstrual dysphoric disorder are better at detecting facial emotions and show a premenstrual dysphoric disorder premenstrual emotion detection advantage. This tendency for women with premenstrual dysphoric disorder to better detect emotions in others, particularly when they are in the premenstrual cycle phase, would have benefits. As one of the first reports of a potentially beneficial effect of premenstrual syndrome for women, the findings may help decrease stigma associated with premenstrual dysphoric disorder and premenstrual syndrome. Further research is needed to replicate and extend these findings.

Comparison of premenstrual symptoms, psychological well-being, and nutritional status between Palestinian women with and without polycystic ovarian syndrome: a case-control study.

BACKGROUND: Polycystic ovarian syndrome (PCOS) is a widely seen reproductive and endocrinological disorder. PCOS can exert substantial effects on many aspects of an individual's life, including reproductive health and psychological well-being. The objective of this study was to assess the nutritional status, premenstrual syndrome, and mental health of women affected by PCOS in comparison to women without PCOS. METHODOLOGY: A case-control observational study in Palestine included 100 PCOS patients and 200 healthy women. The collected data included socio-demographic information, medical history, premenstrual syndrome, mental health, nutritional status, and lifestyle. Anthropometric measurement and the Mediterranean Diet Adherence Screener (MEDAS) were used to evaluate the nutritional status. The General Health Questionnaire (12-GHQ) was used to evaluate the state of mental health. Premenstrual syndrome (PMS) severity was evaluated using a validated Arabic premenstrual syndrome questionnaire. RESULTS: The study's findings indicated that there was a statistically significant increase in the three dimensions of PMS among participants with PCOS, p < 0.05. Similarly, PCOS patients demonstrated elevated ratings across all aspects of mental health, p < 0.05. In terms of the other variables, it has been observed that PCOS patients have a notably greater prevalence of perceived sleep disturbances and decreased adherence to the Mediterranean diet. Regression analysis revealed that PCOS is associated with mental health problems indicated by a higher GHQ score (OR: 1.09; 95% CI: 1.03; 1.16, p < 0.05), lower adherence to the MD diet (OR: 0.86; 95% CI: 0.76; 0.98, p < 0.05), and pre-menstrual syndrome, especially the physical symptoms (OR: 1.06; 95% CI: 1.003; 1.12, p < 0.05) after adjusting for age, smoking, waist-hip ratio, and body mass index (BMI). CONCLUSION: The study has linked polycystic ovary syndrome to negative mental health outcomes and an increased severity of premenstrual syndrome (PMS). Additional investigation is required in order to establish a causal association between polycystic ovary syndrome (PCOS) and lifestyle behaviors within the Palestinian population. Intervention and instructional studies are necessary to investigate the efficacy of management strategies in alleviating the effects of polycystic ovary syndrome (PCOS) on both physical and mental well-being.

Association between premenstrual syndrome and eating disturbance in college students: a cross-sectional study.

BACKGROUND: Premenstrual syndrome (PMS) is a severe problem in women, and a well-balanced diet helps improve PMS symptoms. Eating disturbances are a major health problem in young women. Limited research has explored the correlation between eating behaviors and PMS symptoms in Japan. This study aimed to compare eating disturbances and the severity of PMS symptoms in college students. METHODS: This study was conducted among female college students using an online questionnaire. The questionnaire included basic information (age, height, and weight), PMS symptoms, and eating behaviors assessed using the Eating Attitudes Test 26. RESULTS: The proportion of those with PMS symptoms who were disturbed by PMS symptoms was significantly higher in the group with eating disturbance. Those who were affected by the physical symptoms of PMS had significantly higher scores on the subscales related to diet, bulimia and food preoccupation. CONCLUSION: The results showed an association between PMS symptom severity and eating disturbance. The findings of this study indicate that individuals with eating disturbances may experience adverse effects on PMS symptoms, even in cases where weight is not at the extremes of excessive underweight or obesity.

Relationships between Premenstrual Syndrome (PMS) and Diet Composition, Dietary Patterns and Eating Behaviors.

Premenstrual Syndrome (PMS) is a disorder between gynecology and psychiatry which includes cognitive, affective, and somatic symptoms from mild to severe. The most severe form of PMS is premenstrual dysphoric disorder (PMDD) and it is considered a form of depressive disorder. An association between diet composition and the occurrence of PMS and its severity have been suggested. As such, this manuscript discusses the relationships between diet composition, dietary patterns and eating behaviors, and PMS. PubMed, Embase, Cochrane, and Web of Science databases were searched for related studies up to 18 January 2024. A text search with the following keywords singly or in combination was conducted: "Premenstrual syndrome", "Nutrition", "Diet composition", "Dietary patterns", and "Eating behaviors". Studies published so far showed that low intake of simple carbohydrates, fats, salt, and alcohol, and high of fresh, unprocessed foods rich in B vitamins, vitamin D, zinc, calcium, and omega-3 fatty acids may help prevent the onset of PMS and reduce the severity of its symptoms. However, further studies are needed to formulate definitive recommendations for the use of vitamins, micronutrients and other dietary ingredients supplementation in women with PMS to improve functioning, overall well-being, and physical health. Large, randomized, double-blind clinical trials across diverse populations are necessary to formulate clear recommendations for supplementation in women with PMS.

Effects of E4/DRSP on self-reported physical and emotional premenstrual and menstrual symptoms: data from the phase 3 clinical trial in Europe and Russia.

PURPOSE: To describe the effects of estetrol (E4) 15 mg/drospirenone (DRSP) 3 mg on physical and emotional premenstrual and menstrual symptoms. MATERIALS AND METHODS: We used Menstrual Distress Questionnaire (MDQ) data from a phase-3 trial (NCT02817828) in Europe and Russia with participants (18 - 50 years) using E4/DRSP for up to 13 cycles. We assessed mean changes in MDQ-t-scores from baseline to end of treatment in premenstrual (4 days before most recent flow) and menstrual (most recent flow) scores for 4 MDQ domains in starters and switchers (use of hormonal contraception in prior 3 months) and performed a shift analysis on individual symptoms within each domain. RESULTS: Of 1,553 treated participants, 1,398(90.0%), including 531(38%) starters, completed both MDQs. Starters reported improvements for premenstrual Pain (-1.4), Water Retention (-3.3) and Negative Affect (-2.5); and for menstrual Pain (-3.5), Water Retention (-3.4), and Negative Affect (-2.7) (all p < 0.01). For switchers, no changes were significant except an increase in premenstrual (+1.0, p = 0.02) and menstrual (+1.5, p = 0.003) Water Retention. We observed a change in symptom intensity in >40% of participants for Cramps, Backache and Fatigue (domain Pain), Painful or Tender Breast and Swelling (domain Water Retention) and Mood Swings and Irritability (domain Negative Affect). CONCLUSION: E4/DRSP starters experienced significant improvements in the domains Pain, Water Retention and Negative Affect particularly benefiting those with more severe baseline symptoms. Switchers showed minimal changes.

A phase 3 study in Europe and Russia showed that Estetrol/Drospirenone, a new combined oral contraceptive, significantly improved the MDQ scores for domains Pain, Water Retention and Negative Affect in women starting COC use, while switchers showed minimal changes.

Premenstrual syndrome and lifestyle: Development and validity of a Premenstrual Syndrome Quality-Of-Life Scale.

BACKGROUND: Premenstrual Syndrome significantly affects young women's quality of life, encompassing psychological and clinical symptoms. The aim of this study is to develop a comprehensive and reliable Premenstrual Syndrome Quality of Life Scale and identify factors that affect women's quality of life. METHODS: A methodological and descriptive study was conducted to develop a Premenstrual Syndrome Quality of Life Scale in three phases. Initially, a literature review and qualitative interviews were conducted to generate an item pool. In the second phase, the validity and reliability of the scale were tested. Exploratory Factor Analysis, Confirmatory Factor Analysis were used to confirm the validity and Cronbach's Alpha coefficient was calculated for reliability. In the final phase, the psychometric properties of the scale were evaluated. RESULTS: A 28-item scale was developed in phase one. In Phase two 260 women were participated. Factor analysis confirmed the scale's validity with a KMO measure of 0.837 and significant Bartlett's Sphericity Test (p < 0.000). Confirmatory factor analysis indicated a good fit for the scale. Reliability analysis showed high reliability for the overall scale and subscales. Phase three included 212 participants diagnosed with premenstrual syndrome. There are no significant correlations between age, menarche age, and overall PMS Quality-of-Life scores. However, higher PMS severity and urban living negatively impact quality of life (p < 0.05). CONCLUSIONS: The Premenstrual Syndrome Quality of Life Scale provides a holistic assessment of premenstrual syndrome impact on women's lives, addressing physical, emotional, and social dimensions.

Prevalence and determinant factors of premenstrual syndrome among secondary and preparatory school students in Dessie city administration, Northeast Ethiopia.

BACKGROUND: In Ethiopia, premenstrual syndrome (PMS) was predominantly studied among university students who were in their early 20s; as a result, little is known about the prevalence of premenstrual syndrome among adolescent girls. Therefore, this study aimed to determine the prevalence of premenstrual syndrome and identify factors associated with premenstrual syndrome among secondary school female students in the Dessie city administration, 2023. METHODS: An institutional-based cross-sectional study was conducted involving a sample of 630 participants. A structured self-administered data collection tool was used to gather the necessary information. To ensure data quality, the pretesting and training of the data collectors and supervisors were conducted. The collected data were entered into Epi-data software and analyzed using SPSS version 25. Frequency tables, graphs, means, and medians were used to describe the characteristics of the study participants. Binary logistic regression was employed to identify significant factors. Variables with a p-value ≤ 0.05 with 95% confidence interval (CI) of adjusted odds ratio (AOR) in the final multivariable logistic regression were reported as statistically significant factors associated with PMS. Model fitness was evaluated using the Hosmer and Lemeshow goodness-of-fit test. RESULTS: In the present study, the prevalence of PMS was 22%, 95% CI = 19-26%. FACTORS: Age ≥ 18 years (AOR = 0.54; 95% CI: 0.34, 0.86), duration of menstruation ≥ 7 days (AOR = 3.61; 95% CI: 1.25, 10.37), presence of chronic illness (AOR = 2.08; 95% CI:1.04, 4.16), coffee intake (AOR = 6.05; 95% CI: 2.05, 17.87), alcohol intake (AOR = 0.49; 95% CI: 0.28, 0.86), use of pain medication (AOR = 2.06; 95% CI:1.10, 3.86), use of hormonal contraceptives (AOR = 3.9; 95% CI:1.58, 9.62), sleep disturbance (AOR = 3.82; 95% CI: 2.29, 6.42) and physical exercise (AOR = 0.50; 95% CI: 0.28, 0.87) were significantly associated with PMS. CONCLUSION: A significant number of students in this study were affected by premenstrual syndrome. Age, duration of menstruation, presence of chronic illness, coffee intake, use of pain medication, use of hormonal contraceptives, and sleep disturbance were significantly associated with PMS. Students should avoid excessive use of alcohol, coffee intake and use of pain medication without prescription.

Efficacy of the Flo App in Improving Health Literacy, Menstrual and General Health, and Well-Being in Women: Pilot Randomized Controlled Trial.

BACKGROUND: Reproductive health literacy and menstrual health awareness play a crucial role in ensuring the health and well-being of women and people who menstruate. Further, awareness of one's own menstrual cycle patterns and associated symptoms can help individuals identify and manage conditions of the menstrual cycle such as premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD). Digital health products, and specifically menstrual health apps, have the potential to effect positive change due to their scalability and ease of access. OBJECTIVE: The primary aim of this study was to measure the efficacy of a menstrual and reproductive health app, Flo, in improving health literacy and health and well-being outcomes in menstruating individuals with and without PMS and PMDD. Further, we explored the possibility that the use of the Flo app could positively influence feelings around reproductive health management and communication about health, menstrual cycle stigma, unplanned pregnancies, quality of life, work productivity, absenteeism, and body image. METHODS: We conducted 2 pilot, 3-month, unblinded, 2-armed, remote randomized controlled trials on the effects of using the Flo app in a sample of US-based (1) individuals who track their cycles (n=321) or (2) individuals who track their cycles and are affected by PMS or PMDD (n=117). RESULTS: The findings revealed significant improvements at the end of the study period compared to baseline for our primary outcomes of health literacy (cycle tracking: D̄=1.11; t311=5.73, P<.001; PMS or PMDD: D̄=1.20; t115=3.76, P<.001) and menstrual health awareness (D̄=3.97; t311=7.71, P<.001), health and well-being (D̄=3.44; t311=5.94, P<.001), and PMS or PMDD symptoms burden (D̄=-7.08; t115=-5.44, P<.001). Improvements were also observed for our secondary outcomes of feelings of control and management over health (D̄=1.01; t311=5.08, P<.001), communication about health (D̄=0.93; t311=2.41, P=.002), menstrual cycle stigma (D̄=-0.61; t311=-2.73, P=.007), and fear of unplanned pregnancies (D̄=-0.22; t311=-2.11, P=.04) for those who track their cycles, as well as absenteeism from work and education due to PMS or PMDD (D̄=-1.67; t144=-2.49, P=.01). CONCLUSIONS: These pilot randomized controlled trials demonstrate that the use of the Flo app improves menstrual health literacy and awareness, general health and well-being, and PMS or PMDD symptom burden. Considering the widespread use and affordability of the Flo app, these findings show promise for filling important gaps in current health care provisioning such as improving menstrual knowledge and health.

Association between physical activity and risk of premenstrual syndrome among female college students: a systematic review and meta-analysis.

BACKGROUND: This study aimed to analyze the relationship between physical activity and the risk of premenstrual syndrome among college students. METHODS: Eligible studies were searched from the PubMed, Web of Science, and Embase databases. The link between physical activity and the risk of premenstrual syndrome was evaluated using odds ratio (OR) and 95% confidence interval (CI). The heterogeneity of the included studies was tested and their sources were explored by subgroup analysis. A sensitivity analysis was performed to assess the effect of a single study on the pooled results. The included studies were evaluated for publication bias. Five moderate-quality studies were included in this meta-analysis. RESULTS: Physical activity levels were negatively associated with risk of premenstrual syndrome among college students (OR [95%CI] = 1.46 [1.09, 1.96], P = .011). The pooled results were not influenced after being stratified by the study region and whether multi-factor correction was performed or not. Publication bias was not observed in the included studies. CONCLUSION: A high level of physical activity is dramatically associated with a reduced risk of premenstrual syndrome among female college students.

ShuYu capsule alleviates emotional and physical symptoms of premenstrual dysphoric disorder: Impact on ALLO decline and GABAA receptor δ subunit in the PAG area.

Premenstrual dysphoric disorder (PMDD) is a severe subtype of premenstrual syndrome in women of reproductive age, with its pathogenesis linked to the heightened sensitivity of type A γ -aminobutyric acid receptors (GABAAR) to neuroactive steroid hormone changes, particularly allopregnanolone (ALLO). While a low dose of fluoxetine, a classic selective serotonin reuptake inhibitor, is commonly used as a first-line drug to alleviate emotional disorders in PMDD in clinical settings, its mechanism of action is related to ALLO-GABAA receptor function. However, treating PMDD requires attention to both emotional and physical symptoms, such as pain sensitivity. This study aims to investigate the efficacy of ShuYu capsules, a traditional Chinese medicine, in simultaneously treating emotional and physical symptoms in a rat model of PMDD. Specifically, our focus centres on the midbrain periaqueductal grey (PAG), a region associated with emotion regulation and susceptibility to hyperalgesia. Considering the underlying mechanisms of ALLO-GABAA receptor function in the PAG region, we conducted a series of experiments to evaluate and define the effects of ShuYu capsules and uncover the relationship between the drug's efficacy and ALLO concentration fluctuations on GABAA receptor function in the PAG region. Our findings demonstrate that ShuYu capsules significantly improved oestrous cycle-dependant depression-like behaviour and reduced stress-induced hyperalgesia in rats with PMDD. Similar to the low dose of fluoxetine, ShuYu capsules targeted and mitigated the sharp decline in ALLO, rescued the upregulation of GABAAR subunit function, and activated PAG neurons in PMDD rats. The observed effects of ShuYu capsules suggest a central mechanism underlying PMDD symptoms, involving ALLO_GABAA receptor function in the PAG region. This study highlights the potential of traditional Chinese medicine in addressing both emotional and physical symptoms associated with PMDD, shedding light on novel therapeutic approaches for this condition.
