The Comparison of Irisin, Subfatin, and Adropin in Normal-Weight and Obese Polycystic Ovary Syndrome Patients.

Background: A combination of genetic and environmental factors contribute to the highly common, complex, and varied endocrine condition known as polycystic ovary syndrome (PCOS) in women. PCOS primarily affects women between the ages of 15 and 35 who are in the early to late stages of pregnancy. Thus, this study aimed to evaluate the serum levels of irisin, subfatin, and adropin in PCOS with and without obesity compared to the control group. Methods: The present cross-sectional study was conducted in 2022 at Al-Nahrain University/Department of Chemistry (Baghdad, Iraq). The serum levels of irisin, subfatin, and adropin were measured with the enzyme-linked immunosorbent assay (ELISA) method. Body mass index, lipid profile, insulin, fasting glucose, follicle-stimulating hormone, and luteinizing hormone levels were also evaluated. The data were analyzed using one-way analysis of variance (ANOVA) by GraphPad Prism software version 8.0.2. A P<0.05 was considered statistically significant. Results: The study population comprised PCOS patients (n=90, divided into 45 obese and 45 normal weight) and healthy women (n=30). According to the results, the serum levels of irisin were significantly higher (P<0.001) in obese and normal-weight PCOS patients than controls. While adropin and subfatin were significantly lower in PCOS than controls (P<0.001). Moreover, there are higher levels of serum insulin, fasting glucose, and luteinizing hormone in PCOS women than in healthy women. Conclusion: According to the findings, PCOS patients had a higher level of irisin than the controls. In addition, decreased subfatin and adropin levels were observed in PCOS patients compared with healthy women. Further research is required to confirm these results in the future.

Deciphering the Pharmacological Mechanisms of Wen-Jing-Zhi-Tong Decoction in Treating Primary Dysmenorrhea by UPLC-Q-ExactiveOrbitrap-MS/MS with GC-MS and Network Pharmacology.

BACKGROUND: Primary dysmenorrhea (PDM) is a prevalent menstrual disorder among women, often underreported and undertreated. Wen-Jing-Zhi-Tong Decoction (WJZTD), a patented Traditional Chinese Medicine (TCM) herbal decoction, has shown efficacy in treating PDM. However, the underlying therapeutic mechanism of WJZTD in PDM treatment remains to be elucidated. OBJECTIVE: This study aimed to employ integrative pharmacology and experimental validation to investigate the potential therapeutic mechanisms of WJZTD in treating PDM. METHODS: The bioactive compounds of WJZTD were identified by UPLC-Q-Exactive-Orbitrap MS/MS and GC-MS. Putative targets of WJZTD were obtained from Swiss Target Prediction, STITCH, and BATMAN-TCM databases. Known targets of PDM were retrieved from Gene Cards and Drug Bank databases. Protein-to-protein interactions were constructed to screen key targets using the STRING database. Subsequently, GO and KEGG pathway enrichment analyses were performed based on Metascape. Finally, a PDM rat model was established to validate the potential therapeutic mechanisms of WJZTD using Western Blot, PCR, and ELISA. RESULTS: 390 bioactive compounds in WJZTD were identified through UPLC-Q-ExactiveOrbitrap MS/MS and GC-MS. Network pharmacology revealed 7 key compounds with 20 targets and pathways that are crucial for WJZTD in treating PDM. Behavioral tests confirmed that WJZTD can effectively ameliorate menstrual pain in PDM. WJZTD also inhibited prostaglandin production, thereby relieving uterine smooth muscle contraction. The downregulation of the BDNF/TrkB/ERK/CREB signaling pathway, identified as the key target and pathway through network pharmacology, may be crucial to the anti-nociceptive and anti-inflammatory effects of WJZTD in treating PDM. CONCLUSION: This study provides the first comprehensive analysis of the key compounds, targets, and pathways of WJZTD, laying a solid foundation for future pharmacological studies on PDM. The anti-nociceptive and anti-inflammatory effect may be attributed to the downregulation of the BDNF/TrkB/ERK/CREB signaling pathway.

Menstrual symptoms and subjective well-being among postmenarchal adolescents.

BACKGROUND: Menstrual symptoms are predominantly studied among adults but may occur directly after menarche. Adolescent menstrual healthcare, however, faces specific obstacles and more research into menstrual symptoms as a determinant of adolescent well-being is therefore advocated. OBJECTIVE: This study aimed to investigate menstrual symptoms and their impact on everyday life and well-being among postmenarchal adolescents. STUDY DESIGN: A survey was delivered to a random sample of 1644 schoolgirls, drawn from a population-based project involving 116 lower secondary education schools (7th and 8th grade) in Stockholm, Sweden. Menstrual symptoms (ie, dysmenorrhea, heavy bleeding, irregular periods, mood disturbance, other general symptoms) were investigated through multiple choice questions and defined according to their impact on everyday life as mild (seldom affected), moderate (affected but possible to cope) and severe (affected and difficult to cope). Subjective well-being was measured with the World Health Organization Five Well-Being index. Postmenarchal respondents were eligible for analysis; those with incomplete outcome data or using hormonal contraception were excluded. The frequency and severity of symptoms across different postmenarchal years (1st, 2nd, 3rd, 4th, or 5th+ year after menarche) were studied with Chi-square and Kendall's tau statistics. Analysis of variance was used to study the association between menstrual symptoms and World Health Organization Five Well-Being index scores. A composite menstrual health index variable was obtained through principal component analysis and used to study the overall impact of menstrual symptoms on well-being in regression analyses. RESULTS: Of 1100 postmenarchal girls (mean age, 14.1±0.7 years), 93.2% reported menstrual symptoms, 81.3% had at least 1 moderate symptom and 31.3% had at least 1 severe symptom. The most frequent symptoms were dysmenorrhea (80.4%) and mood disturbance (81.1%), followed by irregular periods (67.9%), heavy bleeding (60.4%), and other general symptoms (60.4%). Throughout postmenarchal years, there was a significant increase in frequency and severity (P<.001) of dysmenorrhea (τ=0.148), heavy bleeding (τ=0.134), mood disturbance (τ=0.117), and other general symptoms (τ=0.110), but not irregular periods (τ=-0.0201; P=.434). Girls with menstrual symptoms had significantly lower World Health Organization Five Well-Being index scores than those without symptoms (mean difference, -17.3; 95% confidence interval, -22.4 to -12.3). Analysis of variance showed significant associations (P<.001) with World Health Organization Five Well-Being index scores for each of the examined menstrual symptoms. In post hoc pairwise comparisons with peers without symptoms, the greatest reductions in World Health Organization Five Well-Being index score were found among girls with severe symptoms (mean difference for: dysmenorrhea, -20.72; heavy bleeding, -15.75; irregular periods, -13.81; mood disturbance, -24.97; other general symptoms, -20.29), but significant differences were observed even for moderate or mild symptoms. The composite menstrual health index was significantly associated with World Health Organization Five Well-Being index scores in regression analysis, independently of age, age at menarche, body mass index, smoking, physical activity, own and parental country of birth, biparental care, and socioeconomic status. CONCLUSION: Despite growing awareness about the relevance of menstruation to women's health, unmet menstrual health needs are a potential threat to the well-being of adolescents. Education, screening, and clinical competence are important tools to reduce the burden of menstrual symptoms during adolescence and to prevent long-term consequences. The development of novel person-centered strategies should be a priority for clinical practice and research in adolescent menstrual health.

Menstrual Changes Following COVID-19 Vaccination: A Cross-Sectional Study.

Background and Objectives: Menstrual changes, including altered cycle length and bleeding patterns, have been reported following COVID-19 vaccination. This study aimed to determine the prevalence and types of menstrual changes occurring after COVID-19 vaccination among female students and staff at a university in Saudi Arabia. Materials and Methods: A cross-sectional study was conducted among women aged 18-39 years who received at least one dose of a COVID-19 vaccine. Eligible participants, including university students and staff, were recruited between May 2022 and November 2022. Participants completed a questionnaire detailing their sociodemographic characteristics, general medical and reproductive history, and menstrual characteristics before and after vaccination. The prevalence of various menstrual changes (cycle length, bleeding days, flow, and mid-cycle spotting) was calculated. The demographic factors associated with menstrual changes were analyzed using chi-squared tests. Results: The 472 included participants had a mean age of 20.9 years, and 95.3% were unmarried. Changes in menstrual cycle characteristics after COVID-19 vaccination were reported by 54.7% of respondents overall. The most common change was in cycle length, followed by the number of menstruation days and bleeding flow. Menstrual changes were not associated with age, BMI, occupation, marital status, or medical history. Changes in intermenstrual bleeding were more frequently reported after the third dose of the Pfizer vaccine compared to the Moderna vaccine (p = 0.014). Conclusions: More than half of the recruited female students and staff reported menstrual changes following COVID-19 vaccination, with altered cycle length being the most common. The potential underlying mechanisms and implications of these menstrual alterations require further investigation. These findings provide evidence of the menstrual side effects of COVID-19 vaccines among women in Saudi Arabia.

Prevalence, pain intensity and symptoms associated with primary dysmenorrhea: a cross-sectional study.

BACKGROUND: Primary dysmenorrhea (PD) is an etiological cyclic pelvic pain related to the menstrual period; it can negatively impact women's quality of life and productivity. The aim of the present study was to estimate the prevalence of PD and analyze associated symptoms in Brazilian women. METHODS: An online cross-sectional study was carried out in Brazil, with a structured questionnaire regarding dysmenorrhea and associated symptoms. PD intensity was measured with the Numerical Rating Scale for Pain and classified as mild (1-3), moderate (4-7) and severe (> 8). The association between qualitative variables was performed using Pearson's Chi-Square Test. The quantification of this association was measured using multinomial logistic regression models, with calculation of Odds Ratio and confidence interval. A significance level of 5% was considered. RESULTS: A total of 10,070 women were included. Most participants classified PD intensity as moderate (40.4%, 41.9% and 49.7%) and severe (21.2%, 24.8% and 28.4%) in the previous month, 3 months and 5 years, respectively. The most common symptoms associated with PD were irritability, abdominal distension sensation, anxiety and feeling more emotional. The increased of the risk (OR > 1.0) for moderate and severe PD-related pain intensity is related to age, nulliparity and presence PD since adolescence. CONCLUSION: There is a high prevalence of PD among Brazilian women, and the most common symptoms reported were irritability, abdominal distension sensation, anxiety and feeling more emotional.

Prevalence of menstrual irregularities after coronavirus disease 2019 vaccination: A cross-sectional study in the Eastern Province, Saudi Arabia.

BACKGROUND: Reports indicate that there are menstrual cycle disturbances following coronavirus disease 2019 (COVID-19) vaccination. The present study explored the prevalence of menstrual irregularities after COVID-19 vaccination and the association of menstrual irregularities with vaccine type, doses, immediate adverse effects, history of COVID-19 infection, and its severity. MATERIALS AND METHODS: For this cross-sectional study, 406 women of reproductive age completed an online survey about the postvaccine changes in their menstruation (cycle duration, bleeding days, and bleeding amount), COVID-19 vaccine history (doses, type of vaccine, and immediate adverse effects), history of COVID-19 infection, and its severity. Data was analyzed using SPSS; descriptive statistics were computed and Chi-square test, and binary logistic regression analysis were performed. RESULTS: Of the total 406 women, 45% reported postvaccine changes in their menstrual cycle. The most common menstrual change was increased dysmenorrhea (68%), followed by an increase in the length of the cycle (52%). There was a significant association between postvaccine menstrual changes and the age, marital status, and family history of menstrual irregularities. No association was observed between postvaccine menstrual changes and COVID-19 vaccine-and COVID-19 infection-related variables. As per the best-fit model of our predictors, the odds of having postvaccine menstrual changes were 0.41 times less in "single" women (confidence interval [CI] = 0.26-0.27; P < 0.001) and 1.714 times greater in women who had a "family history of menstrual irregularities" (CI = 1.092-2.690; P = 0.02), respectively. CONCLUSION: A substantial number of women complained of postvaccine menstrual changes regardless of their age, type of COVID-19 vaccine, doses, immediate adverse effects, and COVID-19 infection history/severity. Being "single" decreased the probability, whereas having a family history of menstrual irregularities increased the probability significantly of having postvaccine menstrual changes.

Vacuna contra la COVID-19 y menstruación, desde el desconocimiento a la información: revisión sistemática / Vaccine against COVID-19 and menstruation, from ignorance to information: a systematic review

La creación de una vacuna para enfrentar la pandemia de COVID-19 conllevó un vacío de información sobre las posibles alteraciones del ciclo menstrual. El objetivo fue verificar las posibles alteraciones que se pudiesen haber generado en el ciclo menstrual de las mujeres posterior a la inoculación de la vacuna contra la COVID-19. Se realizó una revisión sistemática en las bases bibliografías Medline, Medline Complete, LILACS, CINAHL y ScIELO, utilizando los descriptores “Women”, “Woman”, “Fertile period”, “Vaccination”, “Mass vaccination”, “Immunization”, “COVID-19 vaccines”, “SARS-CoV-2 infection”, “COVID-19”, “Menstrual cycle”, “Menstruation”, “Endometrial cycle”, “Dysmenorrhea” y “Menstruation disturbances”. Mediante la utilización del protocolo PRISMA, de los 319 artículos localizados, 17 fueron incluidos en el análisis. La mayoría de los estudios incluyeron, principalmente, las vacunas Pfizer, Moderna, AstraZeneca y Johnson&Johnson/Janssen con una a tres dosis administradas. El porcentaje de ciclos menstruales alterados fue del 8,0% al 77,8%, y la alteración con mayor frecuencia referida fue la duración del ciclo menstrual, que fue desde 0,3 hasta 12 días de retraso de la menstruación. Todos los estudios refieren cambios en el ciclo menstrual con diversas prevalencias, con y sin significación estadística; sin embargo, también concluyen que estas alteraciones son reversibles y en un corto periodo de tiempo.

The creation of a vaccine to face the COVID-19 pandemic, led to an information gap on possible alterations of the menstrual cycle. The objective was to verify the possible alterations that could have been generated in the menstrual cycle of women, after the inoculation of the vaccine against COVID-19. A systematic review was carried out in the Medline, Medline Complete, LILACS, CINAHL and ScIELO bibliographic databases, using the descriptors “Women”, “Woman”, “Fertile period”, “Vaccination”, “Mass vaccination”, “Immunization”, “COVID-19 vaccines”, “SARS-CoV-2 infection”, “COVID-19”, “Menstrual cycle”, “Menstruation”, “Endometrial cycle”, “Dysmenorrhea” and “Menstruation disturbances”. Using the PRISMA protocol, of the 319 articles located, 17 were included in the analysis. Most of the studies mainly included the Pfizer, Moderna, AstraZeneca and Johnson&Johnson/Janssen vaccines with one to three doses administered. The percentage of altered menstrual cycles ranged from 8.0% to 77.8%, and the most frequently reported alteration was the length of the menstrual cycle, which occurred from 0.3 to 12 days late in menstruation. All the studies refer to changes in the menstrual cycle with different prevalences, with and without statistical significance; however, the same studies also conclude that these alterations are reversible and in a short period of time.

Menstrual disturbances and its association with sleep disturbances: a systematic review.

BACKGROUND: Menstrual disturbances harm women's health, and general well-being. As growing evidence highlights the relationship between sleep and menstrual disturbances, it is imperative to comprehensively examine the association between sleep and menstrual disturbance considering the multiple dimensions of sleep. This systematic review aims to identify the association between sleep and menstrual disturbances by evaluating using Buysse's sleep health framework. METHODS: A comprehensive search of the literature was conducted in PubMed, EMBASE, psychINFO, and CINAHL to identify publications describing any types of menstrual disturbances, and their associations with sleep published between January 1, 1988 to June 2, 2022. Quality assessment was conducted using the Joanna Briggs Institute Critical Appraisal Checklist for Analytical Cross-Sectional Studies. The findings were iteratively evaluated menstrual disturbances and their association with sleep using Buysse's sleep health framework. This framework understands sleep as multidimensional concept and provides a holistic framing of sleep including Satisfaction, Alertness during waking hours, Timing of sleep, Efficiency, and Sleep duration. Menstrual disturbances were grouped into three categories: premenstrual syndrome, dysmenorrhea, and abnormal menstrual cycle/heavy bleeding during periods. RESULTS: Thirty-five studies were reviewed to examine the association between sleep and menstrual disturbances. Premenstrual syndrome and dysmenorrhea were associated with sleep disturbances in sleep health domains of Satisfaction (e.g., poor sleep quality), Alertness during waking hours (e.g., daytime sleepiness), Efficiency (e.g., difficulty initiating/maintaining sleep), and Duration (e.g., short sleep duration). Abnormal menstrual cycle and heavy bleeding during the period were related to Satisfaction, Efficiency, and Duration. There were no studies which investigated the timing of sleep. CONCLUSIONS/IMPLICATIONS: Sleep disturbances within most dimensions of the sleep health framework negatively impact on menstrual disturbances. Future research should longitudinally examine the effects of sleep disturbances in all dimensions of sleep health with the additional objective sleep measure on menstrual disturbances. This review gives insight in that it can be recommended to provide interventions for improving sleep disturbances in women with menstrual disturbance.

Sharp Versus Electric Suction Curettage in Gynecologic Patients Undergoing Evaluation for Abnormal Uterine Bleeding.

STUDY OBJECTIVE: Suction curettage is preferred over sharp curettage in obstetric settings. We compare the quality of operative tissue sampling between sharp curettage and suction curettage using electric vacuum aspiration for nonobstetric abnormal uterine bleeding in reproductive-aged women. DESIGN: A retrospective cohort study. SETTING: Community hospital in Long Island, New York. PATIENTS: Women ages 21 to 45 years (n = 257) who underwent operative curettage procedure for nonobstetric abnormal uterine bleeding. INTERVENTIONS: Independent ratings of specimens from suction curettage using electric vacuum aspiration and sharp curettage by 2 pathologists blinded to method of tissue collection. MEASUREMENTS AND MAIN RESULTS: The primary outcome was percentage of organized tissue, indicative of a higher-quality pathology specimen. Specimens obtained by electric suction curettage (p <.001) had a significantly higher percentage of organized tissue (M = 66.28, SD = 20.33) than sharp curettage (M = 55.51, SD = 24.17). There were no differences between the curettage groups for operative time, blood loss, intraoperative complications, or pathology diagnosis. CONCLUSION: Specimens obtained with suction curettage contained more organized tissue with similar pathologist satisfaction and confidence scores than sharp curettage. We suggest clinicians consider electric suction curettage in the diagnostic workup of abnormal uterine bleeding in reproductive-aged women. In addition, patient-centered benefits include no increase in operative time, blood loss, or complication rate compared with sharp curettage.

Menstrual disturbances following COVID-19 vaccination: A probable puzzle about the role of endocrine and immune pathways.

Menstruation is a monthly shedding of the uterine wall, presented by menstrual bleeding in women of reproductive age. Menstruation is regulated by fluctuation of estrogen and progesterone, as well as other endocrine and immune pathways. Many women experienced menstrual disturbances after vaccination against the novel coronavirus in the last two years. Vaccine-induced menstrual disturbances have led to discomfort and concern among reproductive-age women, such that some decided not to receive the subsequent doses of the vaccine. Although many vaccinated women report these menstrual disturbances, the mechanism is still poorly understood. This review article discusses the endocrine and immune changes following COVID-19 vaccination and the possible mechanisms of vaccine-related menstrual disturbances.

Female reproduction and abnormal uterine bleeding after COVID-19 vaccination.

Coronavirus disease 2019 (COVID-19) vaccines have been widely administered throughout the global community to minimize the morbidity and mortality caused by the COVID-19 pandemic. Although generally well-tolerated, these vaccines have generated some unwanted consequences, including thrombosis and menstrual irregularities. The effect of vaccination on female reproductive function has also been questioned. The aim of this review is to give readers a clear understanding of the effects of COVID-19 vaccines on thrombosis, reproductive function, and menstrual irregularities by systemically analyzing the available literature. The available evidence suggests that COVID-19 vaccines have a minimal impact on ovarian reserve. Furthermore, in vitro fertilization outcomes after COVID-19 vaccination remain unimpaired compared to those who did not receive the vaccines. Current evidence supports a certain degree of impact of COVID-19 vaccines on the menstrual cycle, with the most frequent alteration being menstrual irregularity, followed by menorrhagia. These changes are generally well-tolerated and transient, lasting less than 2 months. This review, by providing information with up-to-date references on this issue, may enhance readers' understanding of the impact of COVID-19 vaccines on female reproductive function and the menstrual cycle.

Effects of a 16-Week Digital Intervention on Sports Nutrition Knowledge and Behavior in Female Endurance Athletes with Risk of Relative Energy Deficiency in Sport (REDs).

Female endurance athletes are considered a high-risk group for developing Relative Energy Deficiency in Sport (REDs). Due to the lack of educational and behavioral intervention studies, targeting and evaluating the effects of the practical daily management of REDs, we developed the Food and nUtrition for Endurance athletes-a Learning (FUEL) program, consisting of 16 weekly online lectures and individual athlete-centered nutrition counseling every other week. We recruited female endurance athletes from Norway (n = 60), Sweden (n = 84), Ireland (n = 17), and Germany (n = 47). Fifty athletes with symptoms of REDs and with low risk of eating disorders, with no use of hormonal contraceptives and no chronic diseases, were allocated to either the FUEL intervention (n = 32) (FUEL) or a 16-week control period (n = 18) (CON). All but one completed FUEL, while 15 completed CON. We found strong evidence for improvements in sports nutrition knowledge, assessed via interviews, and moderate to strong evidence in the ratings concerning self-perceived sports nutrition knowledge in FUEL versus CON. Analyses of the seven-day prospective weighed food record and questions related to sports nutrition habits, suggested weak evidence for improvements in FUEL versus CON. The FUEL intervention improved sports nutrition knowledge and suggested weak evidence for improved sports nutrition behavior in female endurance athletes with symptoms of REDs.

Menstrual health and genital hygiene status in adolescent girls and young women with cerebral palsy.

Menstrual health and genital hygiene behavior in patients with cerebral palsy (CP) is underrecognized, undertreated, and negatively affects quality of life. The aim of this case-control study is to compare menstrual health and genital hygiene behaviors in adolescent girls and young women with CP to a healthy women control group. Participants were invited to study via social media tools between August 2021 and February 2022. The study included 74 adolescent girls and young women with CP and 89 healthy women. Menstrual status with semi-structured questions, menstrual symptoms with "Menstrual Symptom Questionnaire (MSQ)," genital hygiene behavior with "Genital Hygiene Behavior Scale (GHBS)" were evaluated. The control group scored significantly higher on the MSQ sub-dimensions of "negative effects somatic complaints" (r = 0.396; p < .001), "menstrual pain" (r = 0.287; p < .001), "coping methods" (r = 0.291; p < .001), and total score (r = 0.395; p < .001), as well as the GHBS sub-dimensions of "awareness of abnormal findings" (r = 0.270; p = .001) and "menstrual hygiene" (r = 0.495; p < .001) and total score (r = 0.393; p < .001). People with CP had worse genital hygiene behavior, had less menstrual symptoms, and behaved differently about the menstruation symptoms. This study focused on adolescent girls and young women with CP who cannot easily express their own experiences and concerns, emphasized that their needs should be identified by determining their menstrual health and genital hygiene behaviors.Clinical Registration Name, Registration Number, Registration Date: Menstrual Health and Genital Hygiene Status in Cerebral Palsy and NCT04985045, August 2,2021.

Pelvic Pain in Transgender People Using Testosterone Therapy.

Purpose: This descriptive study aimed to assess the characteristics of pelvic pain and explore predictive factors for pelvic pain in transgender (trans) individuals using testosterone therapy. Methods: An online cross-sectional survey was open between August 28, 2020, and December 31, 2020, to trans people presumed female at birth, using testosterone for gender affirmation, living in Australia, and >16 years of age. The survey explored characteristics of pelvic pain following initiation of testosterone therapy, type and length of testosterone therapy, menstruation history, and relevant sexual, gynecological, and mental health experiences. Logistic regression was applied to estimate the effect size of possible factors contributing to pain after starting testosterone. Results: Among 486 participants (median age = 27 years), 351 (72.2%)* reported experiencing pelvic pain following initiation of testosterone therapy, described most commonly as in the suprapubic region and as "cramping." Median duration of testosterone therapy was 32 months. Persistent menstruation, current or previous history of post-traumatic stress disorder, and experiences of pain with orgasm were associated with higher odds of pelvic pain after testosterone therapy. No association was observed with genital dryness, intrauterine device use, previous pregnancy, penetrative sexual activities, touching external genitalia, or known diagnoses of endometriosis, vulvodynia, vaginismus, depression, anxiety, or obesity. Conclusions: Pelvic pain is frequently reported in trans people following initiation of testosterone therapy. Given the association with persistent menstruation and orgasm, as well as the known androgen sensitivity of the pelvic floor musculature, further research into pelvic floor muscle dysfunction as a contributor is warranted.

A case series of premenstrual disorders presenting to the UK's National Female Hormone Clinic.

AIMS AND METHOD: We aimed to describe the clinical characteristics of female patients presenting with premenstrual disorders to a tertiary service in the UK. We conducted a retrospective case-note review of referrals to the National Female Hormone Clinic from April 2014 to August 2020. Based on clinical assessment, we determined whether the patient met criteria for premenstrual dysphoric disorder or premenstrual exacerbation of an underlying psychiatric disorder. RESULTS: Of 146 patients seen in clinic for premenstrual disorders, an ICD-10 psychiatric diagnosis was made in 130 (89.0%); a minority 16 (11.0%) did not have a psychiatric diagnosis. Following assessment, 94 patients (64.4%) met criteria for premenstrual dysphoric disorder and 67 (45.6%) had exacerbation of a psychiatric disorder. CLINICAL IMPLICATIONS: Patients presenting to this specialist service had complex psychiatric comorbidity; almost half presented with exacerbation of a psychiatric disorder.

Abnormal uterine bleeding in reproductive age: a comparative analysis between the five Brazilian geographic regions

SUMMARY OBJECTIVE: This study aimed to comparatively evaluate the presence of abnormal uterine bleeding and associated factors among women from the five official Brazilian geographic regions. METHODS: This is a cross-sectional, population-based, multicenter study of reproductive-age women from the five regions of Brazil. All participants answered questionnaires containing personal and socioeconomic data and information on uterine bleeding (self-perception and objective data). RESULTS: A total of 1,761 Brazilian women were included, 724 from the Southeast, 408 from the Northeast, 221 from the South, 213 from the North, and 195 from the Central-West. Considering women's self-perception, the prevalence of abnormal uterine bleeding was 37.56% in the North region, 39.46% in the Northeast, 21.54% in the Central-West, 29.56% in the Southeast, and 25.34% in the South (p<0.001). Abnormal uterine bleeding was more prevalent in the North and Northeast, where women had lower purchasing power, became pregnant more often, and were the only ones financially responsible for supporting the family more often (p<0.001). The menstrual cycle lasted <24 days in less than 20% of the women in all regions (p=NS). Among these, approximately 8 out of 10 women had never undergone treatment in four out of the five regions evaluated. More than half of the evaluated women reported a worsening of their quality of life during bleeding. CONCLUSION: The prevalence of abnormal uterine bleeding in Brazilian women was higher in the North and Northeast, followed by the Southeast, South, and Central-West regions. There was a worsening of quality of life during menstruation regardless of the woman's self-perception of abnormal uterine bleeding. Such results can direct the actions of health managers toward a better approach to abnormal bleeding.

Motor Control and Regularity of Menstrual Cycle in Ankle and Knee Injuries of Female Basketball Players: A Cohort Study.

Inadequate motor control facilitates ankle and knee injuries in female basketball. Although biomechanical analysis could help to detect it, aspects such as irregular menstruation make these associations controversial. We aimed to evaluate associations between 2D biomechanics during landing and proprioception with ankle and knee injuries of female basketball players, considering their menstruation regularity. Seventy-one players participated in this study. In the preseason, participants performed a drop-jump to obtain biomechanics during landing and a weight-bearing proprioception test. During the competitive season, all the non-contact ankle and knee injuries were registered. Data showed that 16% of players sustained an ankle or knee injury, being more frequent in players with irregular menstruation compared to regulars (22% vs. 13%, χ2 = 6.009, p = 0.050, d = 0.6). Players who sustained a left-side injury displayed higher left-side dynamic valgus during landing than uninjured players (χ2 = 25.88, p = 0.006, d = 1.5). The rest of the variables did not show any significant difference (p > 0.05). Monitoring 2D dynamic valgus from a drop-jump could help to detect inadequate motor control that may facilitate ankle or knee injuries of female basketball players, mainly for those with irregular menstruation. Proprioception seems not to be related to injuries.

The Effect of COVID-19 on the Menstrual Cycle: A Systematic Review.

Researchers have been studying COVID-19 from day one, but not much is known about the impact of COVID-19 on the reproductive system, specifically the female reproductive system. There has been substantial anecdotal and media coverage on the effect of COVID-19 on the female reproductive system and changes in the menstrual cycle, but so far available data are not robust enough to draw firm conclusions about the topic. This article was carried out to present already published studies on the correlation between SARS-CoV-2 infection and menstrual cycle changes. A systematic literature search was conducted on the Medline, Scopus, and Cochrane Library databases in accordance with the PRISMA guidelines. Three studies were finally included in the review. The findings of the studies indicate changes in menstrual volume and changes in menstrual cycle length as consequences of SARS-CoV-2 infection; the latter was also the most common menstrual irregularity reported by the included studies. Women have mainly reported decreased menstrual volume and a prolonged cycle. The findings also indicate that the severity of COVID-19 does not play a role in menstrual cycle changes. However, the research on this topic is still too scarce to draw definitive conclusions, and there is a need for further research. The relevant conclusions, which could be drawn only from a well-constructed study, would have a major effect on defining the impact of SARS-CoV-2 infection on the menstrual cycle.

Effect of visceral manipulation on menstrual complaints in women with polycystic ovarian syndrome.

CONTEXT: Research is lacking regarding osteopathic approaches in treating polycystic ovary syndrome (PCOS), one of the prevailing endocrine abnormalities in reproductive-aged women. Limited movement of pelvic organs can result in functional and structural deficits, which can be resolved by applying visceral manipulation (VM). OBJECTIVES: This study aims to analyze the effect of VM on dysmenorrhea, irregular, delayed, and/or absent menses, and premenstrual symptoms in PCOS patients. METHODS: Thirty Egyptian women with PCOS, with menstruation-related complaints and free from systematic diseases and/or adrenal gland abnormalities, prospectively participated in a single-blinded, randomized controlled trial. They were recruited from the women's health outpatient clinic in the faculty of physical therapy at Cairo University, with an age of 20-34 years, and a body mass index (BMI) ≥25, <30 kg/m2. Patients were randomly allocated into two equal groups (15 patients); the control group received a low-calorie diet for 3 months, and the study group that received the same hypocaloric diet added to VM to the pelvic organs and their related structures, according to assessment findings, for eight sessions over 3 months. Evaluations for body weight, BMI, and menstrual problems were done by weight-height scale, and menstruation-domain of Polycystic Ovary Syndrome Health-Related Quality of Life Questionnaire (PCOSQ), respectively, at baseline and after 3 months from interventions. Data were described as mean, standard deviation, range, and percentage whenever applicable. RESULTS: Of 60 Egyptian women with PCOS, 30 patients were included, with baseline mean age, weight, BMI, and menstruation domain score of 27.5 ± 2.2 years, 77.7 ± 4.3 kg, 28.6 ± 0.7 kg/m2, and 3.4 ± 1.0, respectively, for the control group, and 26.2 ± 4.7 years, 74.6 ± 3.5 kg, 28.2 ± 1.1 kg/m2, and 2.9 ± 1.0, respectively, for the study group. Out of the 15 patients in the study group, uterine adhesions were found in 14 patients (93.3%), followed by restricted uterine mobility in 13 patients (86.7%), restricted ovarian/broad ligament mobility (9, 60%), and restricted motility (6, 40%). At baseline, there was no significant difference (p>0.05) in any of demographics (age, height), or dependent variables (weight, BMI, menstruation domain score) among both groups. Poststudy, there was a statistically significant reduction (p=0.000) in weight, and BMI mean values for the diet group (71.2 ± 4.2 kg, and 26.4 ± 0.8 kg/m2, respectively) and the diet + VM group (69.2 ± 3.7 kg; 26.1 ± 0.9 kg/m2, respectively). For the improvement in the menstrual complaints, a significant increase (p<0.05) in the menstruation domain mean score was shown in diet group (3.9 ± 1.0), and the diet + VM group (4.6 ± 0.5). On comparing both groups poststudy, there was a statistically significant improvement (p=0.024) in the severity of menstruation-related problems in favor of the diet + VM group. CONCLUSIONS: VM yielded greater improvement in menstrual pain, irregularities, and premenstrual symptoms in PCOS patients when added to caloric restriction than utilizing the low-calorie diet alone in treating that condition.
