Postpartum menstrual equity: Video and audio analysis of vaginal bleeding counseling during postpartum inpatient care at a southeastern US tertiary hospital.

BACKGROUND: Despite the universal nature of postpartum vaginal bleeding after childbirth and the importance of managing vaginal bleeding in the postpartum period to monitor health status, little is known about the information or products that birthing individuals are provided. Investigating current practices may offer insights to enacting more supportive and equitable postpartum care. OBJECTIVE: To evaluate the patterns and content of vaginal bleeding counseling provided to birthing parents while on a postnatal inpatient unit. DESIGN: Observational study of inpatient postpartum care. Birthing parents and their companions consented to video and audio recording of themselves, their infants, and healthcare team members during their postnatal unit stay. METHODS: Following IRB approval and in coordination with clinicians at a tertiary hospital in the southeastern United States, data were collected with 15 families from August to December 2020. A multidisciplinary team coded video and audio data from each family from 12 h before hospital discharge. This analysis evaluates patterns of vaginal bleeding counseling timing, content, and language concordance and thematic content of this communication. RESULTS: Birthing parent participants were self-identified Hispanic White (n = 6), non-Hispanic Black (n = 5), non-Hispanic White (n = 3), and non-Hispanic multi-race (n = 1). Six were Spanish-speaking and eight had cesarean section births. The timing, content, and language concordance of vaginal bleeding communication varied, with these topics mainly addressed in the hour preceding discharge. Twelve of the 15 birthing parents had communication on these topics between 2 and 5 times, 2 had one exchange, and 1 had no counseling on postpartum bleeding observed. Four of the six Spanish-speaking birthing parents had counseling on these topics that was not language concordant. Postpartum vaginal bleeding management involved the themes of access to products, patient safety, and meaningful counseling. There was a lack of adequate access, variation in accurate and respectful care, and a busy clinical environment with differences in information provided. CONCLUSION: Findings suggest that there are opportunities to strengthen clinical practices for more consistent, proactive, and language concordant vaginal bleeding and subsequent menstrual care postpartum. Menstrual equity is an important part of dignified and safe care.

Video analysis of when and what information on vaginal bleeding was shared between people who just gave birth and their healthcare team at the hospital.Why did we do the study? After birth, people must take care of vaginal bleeding. It is important for people in the hospital to recognize warning signs for too much bleeding, have access to pads, and feel supported by their healthcare team before discharging to home. There has been little research on experiences with inpatient counseling on postpartum vaginal bleeding­a part of the reproductive life cycle­for new parents. We wanted to watch and listen in hospital rooms so we could think about the best ways for healthcare providers to talk about vaginal bleeding. What did we do? We asked 15 people who just gave birth, people staying with them at the hospital, and their healthcare team if we could video and sound record in their hospital rooms. They could start and stop recording anytime. We only recorded people who agreed to be in the study. What did we learn? We watched recordings of the last 12 hours at the hospital before each family went home. We found that most of the time, the healthcare workers did not talk about vaginal bleeding. People who spoke Spanish did not always have someone interpreting into their language. Sometimes family members had to translate and ask for pads. Some people did not have enough pads or underwear and had to wait after asking for more. What does it mean? We found ways to improve teaching about vaginal bleeding after birth. We recommend always having an interpreter when needed, giving people enough pads and underwear in their rooms, including companions in the teaching, and having enough healthcare workers to answer requests. These ideas would improve the counseling and give everyone the support needed after giving birth.

Menstrual hygiene management practice and associated factors among secondary school girls in eastern Ethiopia: The influence of water, sanitation and hygiene facilities.

BACKGROUND: Inadequate water supply, poor sanitation and hygiene (WASH) facilities in schools, insufficient puberty education and a lack of hygienic menstrual hygiene management (MHM) items (absorbents) cause girls in developing countries like Ethiopia to view menstruation as shameful and uncomfortable. However, there was little evidence of female MHM practice and associated factors among secondary school girls in eastern Ethiopia. OBJECTIVE: To assess MHM practice and associated factors among secondary school girls in eastern Ethiopia. DESIGN: Institutional-based cross-sectional study design was conducted. METHODS: A total of 473 secondary schoolgirls were selected using a stratified sampling technique. Data were collected using a self-administered structured questionnaire, double-entered to Epidata version 3.1 and exported to SPSS version 26 for analysis. Descriptive analysis was computed using frequency, percentage, mean and standard deviations. Multivariable logistic regression was applied to assess the association of the school water, sanitation and hygiene facilities with MHM. Adjusted odd ratio (AOR) with its 95% confidence interval was computed to show the strength of the association between dependent and independent variables. The goodness of fit of the model was tested by the Hosmer-Lemeshow goodness of fit test. RESULTS: Out of 473 study participants, 72.93% of them (95% CI: 68.74-76.76) reported good MHM practices. The study also found that availability of continuous water supply (AOR = 2.40, 95% CI: (1.42-4.01)); types of toilet (AOR = 2.01, 95% CI: (1.20-3.40)), confined space (AOR = 3.02, 95% CI: (1.49-4.76)) and having females' toilets alone inside in the school (AOR = 2.70, 95% CI: (1.20-4.40)) were significantly associated with female students' good MHM practice. CONCLUSION: The survey revealed that some of the secondary schoolgirls practiced poor menstrual hygiene management (MHM), which needs further improvement. The study also found that the availability of continuous water supply in the school, types of toilet facility in the school, availability of private space to manage periods at school, learning about MHM in schools and availability of female toilets kept locked inside were factors significantly associated with MHM practice of students, which require integration of Zonal Health and education bureau to jointly work towards the improvement of school WASH facilities.

Understanding the association between menstrual health and hygiene attitudes and personal agency among very young adolescents in Sao Paulo, Brazil: A cross-sectional study.

BACKGROUND: Although menstruation is a monthly biological phenomenon, it is shrouded in stigma and shame which directly impacts health, education, gender equality, decent work, and economic growth. However, there is scarce evidence on how personal agency, an individual's ability to access resources, may act as a protective factor to adequate menstrual health and hygiene practices. Therefore, we assess the association between attitudes toward menstruation and personal agency among very young adolescent girls. METHODS: We use cross-sectional data from the Global Early Adolescent Study in São Paulo, Brazil, among 10- to 14-year-old girls who have experienced menarche (n = 325) and completed a home-based self-administered questionnaire in 2021. "Attitudes toward menstruation" was created based on five indicators on a Likert scale, with a higher score indicating more positive attitudes. The main covariate was personal agency, comprised of three scales and modeled as three continuous variables: voice, decision-making power, and freedom of movement. Data were analyzed using multivariable linear regression. RESULTS: Attitudes toward menstruation mean score was 12.5 (range 5-19). Older adolescents (12-14 years-old) had higher mean scores (more positive) than younger adolescents (10-11 years-old) on attitudes toward menstruation, whereas no other sociodemographic or menstrual health indicator (knowledge or access to products) were associated with attitudes toward menstruation. In the multiple regression model, older age and higher freedom of movement remained positively associated with attitudes toward menstruation (ßadjust = 0.5; 95%CI 0.1 to 0.8). CONCLUSION: Positive attitudes toward menstruation are associated with higher freedom of movement among very young Brazilian adolescent girls. The promotion of personal agency should be recognized as key strategies to accelerate young girls' positive approaches to their own menstruation and, consequently, well-being.

Menstrual Health and Hygiene Attitudes are associated with Personal AgencyOur results show that positive attitudes toward menstruation among very young adolescent girls are associated with personal agency, measured through freedom of movement. This information can inform strategies to accelerate young girls' positive approaches to their own menstruation and, consequently, well-being.

Menstrual Blood Stem Cells-Derived Exosomes as Promising Therapeutic Tools in Premature Ovarian Insufficiency Induced by Gonadotoxic Systemic Anticancer Treatment.

Gonadotoxicity resulting from systemic and locoregional cancer treatments significantly threatens women's reproductive health, often culminating in premature ovarian insufficiency. These therapies, particularly alkylating agents and ionizing radiation, induce DNA damage and apoptosis in ovarian follicles, leading to infertility, amenorrhea, and estrogen deficiency, which exacerbate risks of osteoporosis and cardiovascular diseases. Existing fertility preservation methods do not prevent immediate ovarian damage, underscoring the need for innovative protective strategies. Menstrual blood-derived stem cells (MenSC) and their extracellular vesicles (EV) present promising regenerative potential due to their therapeutic cargo delivery and pathway modulation capabilities. Preclinical studies demonstrate that MenSC-derived EV ameliorate premature ovarian insufficiency by inhibiting granulosa cell apoptosis, promoting angiogenesis, and activating pivotal pathways such as SMAD3/AKT/MDM2/P53. However, comprehensive research is imperative to ensure the safety, efficacy, and long-term effects of MenSC-derived EV in clinical practice. In this review, we update the current knowledge and research regarding the use of MenSC-derived EV as a novel therapeutic weapon for ovarian regeneration in the context of gonadotoxicity induced by systemic anticancer treatment.

'Everyone needs to be educated': pupils' voices on menstrual education.

BACKGROUND: Physical, affective and behavioural symptoms associated with the menstrual cycle are commonplace. Adolescents with problematic symptoms have reported a negative impact on school attendance, behaviour and participation in physical activity. In the United Kingdom, evidence suggests that menstrual health education delivered by teachers focusses on menstrual cycle biology as opposed to management of menstruation and menstrual cycle related symptoms. Through obtaining the pupil voice, this study aimed to understand young people's perceptions and experiences of menstrual education in schools and their experiences of menstruating whilst at school, including within Physical Education. METHODS: To address the aims, a qualitative descriptive study was conducted. Nine focus groups with female pupils (n = 48; ages 10-15 years) were completed across six school locations in England and Wales, including primary and secondary schools. A range of elements relating to the menstrual cycle, education at school and PE were discussed by pupils. RESULTS: Four main themes were developed (a) Education preferences, (b) Period positive environments, (c) Personal experiences and (d) Impact on school. Similarities were reflected across focus groups in terms of current (lacking) education, lesson style and preferences, comfort of conversations, lack of school support and impact on school and PE. CONCLUSION: The findings highlight the lack of menstrual education received and subsequent impact of menstruation and menstrual-related symptoms in school and PE. The abundance of information requested by pupils highlights the deficit in understanding about how to manage periods in school and remain engaged in physical activity. Schools can utilise information from the current study to; create period positive environments; consider lesson content and format; and explore how to support girls to stay physically active in PE.

The swimming habits of women who cold water swim.

BACKGROUND: Cold water swimming is growing in popularity, especially among women. We have previously reported that women felt that cold water swimming helps with their menstrual and menopause symptoms. But little is known about the habits of women who cold water swim. OBJECTIVES: To determine the habits of women who cold water swim. DESIGN: This was a mixed-methods study. METHODS: An online survey asked women who cold water swim about their experience of swimming and how this affected their menstrual and menopause symptoms. The survey was advertised for 2 months on social media, with a focus on advertising in cold water swimming Facebook groups. In this article, only the questions on the women's swimming habits were analyzed. RESULTS: The analysis of 1114 women, mainly from the United Kingdom, revealed that most had been swimming for 1-5 years (79.5%). Most swim in the sea (64.4%), and only 15.5% swim alone. The majority (89.0%) swim all year around, swimming for mainly 30-60 min in the summer and 5-15 min in the winter. The women mostly swim wearing swimming costumes (skins) throughout the year. The majority of the free-text responses showed women found mental and physical benefits from cold water swimming. CONCLUSION: It was not surprising to learn that women swim for longer in the summer than the winter, but hearing how they feel cold water swimming helps their physical and mental health is important. With the limitations on access and safety of many wild swimming sites in the United Kingdom, it is time to ensure that cold water swimming is safer and more supported.

Adverse Menstrual Events Reported After and Before (or Without) COVID-19 Vaccination: A Systematic Review and Meta-Analysis of Comparative Observational Studies.

BACKGROUND: Reports of adverse menstrual events emerged during the COVID-19 vaccination campaign in multiple countries. This raised the question whether these reports were caused by the vaccines. The aim of this systematic review was to evaluate comparative studies on this topic (registered at PROSPERO [CRD42022324973]). METHODS: We included observational studies such as cohort studies and surveys comparing the response to self-reported questionnaires between post- versus pre-vaccination data. PubMed and Cochrane Library searches were conducted on 1 September 2023. The primary outcome was the incidence of any prespecified adverse menstrual event, and the outcome measure was the risk ratio. The meta-analysis was conducted by using the Mantel-Haenszel method and the random effects model. We summarized the results on risk factors as well as key findings of the studies included. RESULTS: We retrieved 161 references from electronic databases and additional sources such as references lists. Of those, we considered 21 comparative observational studies. The meta-analysis of any adverse menstrual adverse event reported in 12 studies resulted in a pooled estimate (risk ratio 1.13; 95% CI, 0.96-1.31) that did not favor any group. The analysis was constrained by considerable clinical and statistical heterogeneity. Risk factors for self-reported menstrual changes included a history of COVID-19 infection, the concern about COVID-19 vaccines, smoking, previous cycle irregularities, depression, and stress, and other issues. CONCLUSIONS: The risk ratio did not favor any group and heterogeneity was prevalent among the studies. Most studies suggested that the reported changes were temporary, minor, and nonserious.

Comparison of clinical outcomes and perinatal outcomes between natural cycle and hormone replacement therapy of frozen-thawed embryo transfer in patients with regular menstruation: a propensity score-matched analysis.

Purpose: To investigate potential differences in pregnancy outcomes among patients with regular menstruation who underwent frozen-thawed embryo transfer using natural cycle (NC) or hormone replacement therapy (HRT). Methods: This study retrospectively analyzed 2672 patients with regular menstruation who underwent FET from November 2015 to June 2021 at the single reproductive medical center. A one-to-one match was performed applying a 0.02 caliper with propensity score matching. Independent factors influencing the live birth and clinical pregnancy rates were screened and developed in the nomogram by logistic regression analysis. The efficacy of live birth rate and clinical pregnancy rate prediction models was assessed with the area under the ROC curve, and the live birth rate prediction model was internally validated within the bootstrap method. Results: The NC protocol outperformed the HRT protocol in terms of clinical pregnancy and live birth rates. The stratified analysis revealed consistently higher live birth and clinical pregnancy rates with the NC protocol across different variable strata compared to the HRT protocol. However, compared to the HRT treatment, perinatal outcomes indicated that the NC protocol was related to a higher probability of gestational diabetes. Multifactorial logistic regression analysis demonstrated independent risk factors for live birth rate and clinical pregnancy rate. To predict the two rates, nomogram prediction models were constructed based on these influencing factors. The receiver operating characteristic curve demonstrated moderate predictive ability with an area under curve (AUC) of 0.646 and 0.656 respectively. The internal validation of the model for live birth rate yielded an average AUC of 0.646 implying the stability of the nomogram model. Conclusion: This study highlighted that NC yielded higher live birth and clinical pregnancy rates in comparison to HRT in women with regular menstruation who achieved successful pregnancies through frozen-thawed embryo transfer. However, it might incur a higher risk of developing gestational diabetes.

Granulosa cell insight: unraveling the potential of menstrual blood-derived stem cells and their exosomes on mitochondrial mechanisms in polycystic ovary syndrome (PCOS).

BACKGROUND: Polycystic ovary syndrome (PCOS) presents a significant challenge in women's reproductive health, characterized by disrupted folliculogenesis and ovulatory dysfunction. Central to PCOS pathogenesis are granulosa cells, whose dysfunction contributes to aberrant steroid hormone production and oxidative stress. Mitochondrial dysfunction emerges as a key player, influencing cellular energetics, oxidative stress, and steroidogenesis. This study investigates the therapeutic potential of menstrual blood-derived stem cells (MenSCs) and their exosomes in mitigating mitochondrial dysfunction and oxidative stress in PCOS granulosa cells. METHODS: Using a rat model of PCOS induced by letrozole, granulosa cells were harvested and cultured. MenSCs and their exosomes were employed to assess their effects on mitochondrial biogenesis, oxidative stress, and estrogen production in PCOS granulosa cells. RESULTS: Results showed diminished mitochondrial biogenesis and increased oxidative stress in PCOS granulosa cells, alongside reduced estrogen production. Treatment with MenSCs and their exosomes demonstrated significant improvements in mitochondrial biogenesis, oxidative stress levels, and estrogen production in PCOS granulosa cells. Further analysis showed MenSCs' superior efficacy over exosomes, attributed to their sustained secretion of bioactive factors. Mechanistically, MenSCs and exosomes activated pathways related to mitochondrial biogenesis and antioxidative defense, highlighting their therapeutic potential for PCOS. CONCLUSIONS: This study offers insights into granulosa cells mitochondria's role in PCOS pathogenesis and proposes MenSCs and exosomes as a potential strategy for mitigating mitochondrial dysfunction and oxidative stress in PCOS. Further research is needed to understand underlying mechanisms and validate clinical efficacy, presenting promising avenues for addressing PCOS complexity.

Causal effects of endometriosis stages and locations on menstruation, ovulation, reproductive function, and delivery modes: a two-sample Mendelian randomization study.

Background: Endometriosis is a chronic inflammatory disease of women during their reproductive years. The relationship between the severity and location of endometriosis and menstruation, ovulation, reproductive function, and mode of delivery remains unclear. Methods: We explored the association between the various phenotypes of endometriosis and menstruation, ovulation, reproductive function, and mode of delivery, using two-sample Mendelian randomization (MR) and summary data on endometriosis stages and locations from the FinnGen consortium and women's menstruation, ovulation, reproductive function, and mode of delivery from OpenGWAS and ReproGen. Inverse-variance weighting was used for the primary MR analysis. In addition, a series of sensitivity analyses, confounding analyses, co-localization analyses, and multivariate MR analyses were performed. Results: MR analysis showed a negative effect of moderate to severe endometriosis on age at last live birth (OR = 0.973, 95% CI: 0.960-0.986) and normal delivery (OR = 0.999, 95% CI: 0.998-1.000; values for endpoint were excluded), ovarian endometriosis on age at last live birth (OR = 0.976, 95% CI: 0.965-0.988) and normal delivery (OR = 0.999, 95% CI: 0.998-1.000; values for endpoint were excluded), and fallopian tubal endometriosis on excessive irregular menstruation (OR = 0.966, 95% CI: 0.942-0.990). Bidirectional MR analysis showed that age at menarche had a negative causal effect on intestinal endometriosis (OR = 0.417, 95% CI: 0.216-0.804). All MR analyses were confirmed by sensitivity analyses, and only the genetic effects of moderate to severe endometriosis on normal delivery and age at last live birth were supported by co-localization evidence. Conclusion: Our findings deepen the understanding of the relationship between various types of endometriosis and menstruation, ovulation, reproductive function, and mode of delivery and clarify the important role of moderate to severe endometriosis.

Self-reported menses physiology is positively modulated by a well-formulated, energy-controlled ketogenic diet vs. low fat diet in women of reproductive age with overweight/obesity.

Weight loss can positively alter female physiology; however, whether dietary carbohydrate- or fat- restriction confer unique effects is less studied. Precisely designed, hypocaloric well-formulated ketogenic diets (KD; ~75% energy for weight maintenance) were compared to isocaloric/isonitrogenous low-fat diet (LFD) on self-reported menses in pre-menopausal overweight and obese women (mean ± SD: 34 ± 10 years, BMI: 32.3 ± 2.7 kg/m2). Women received a precisely-weighed and formulated KD with either twice-daily with ketone salts (KS; n = 6) or a flavor-matched placebo (PL; n = 7) daily for six-weeks. An age and BMI-matched cohort (n = 6) was later assigned to the LFD and underwent the same testing procedures as the KD. Self-reported menses fluctuations were assessed bi-weekly along with measures of body weight, body composition, and fasting serum clinical chemistries using repeated measures ANOVA with Bonferroni post-hoc corrections. Both diets elicited clinically-significant weight-loss (Δ: -7.0 ± 0.5 kg; p < 0.001), primarily from fat-mass (Δ: -4.6 ± 0.3 kg; p < 0.001), and improved insulin-sensitivity and serum lipids (all p < 0.05). Fasting plasma glucose and inflammatory markers were not different between diets. Fasting capillary beta-hydroxybutyrate (R-ßHB) increased significantly during the KD, independent of supplementation (Δ: 1.2 ± 0.3 mM R-ßHB; p < 0.001). Women randomized to the KD+KS (30%) and KD+PL (43%) reported subjective increases in menses frequency and intensity after 14 days, whereas another third reported a regain of menses (>1 year since the last period) after 28 days. No LFD participants reported menses changes. Nutrient-dense, whole-food KDs and LFD improved weight, BMI, body composition, and blood parameters in pre-menopausal women after six-weeks. Changes in self-reported menses were described by most of the KD participants, but none of the LFD women suggesting there may be unique effects of nutritional ketosis, independent of weight loss.

Menstrual hygiene management interventions and their effects on schoolgirls' menstrual hygiene experiences in low and middle countries: A systematic review.

BACKGROUND: Inadequate menstrual hygiene management can result in physical, social, psychological, and educational challenges for schoolgirls. To address these issues, researchers have conducted intervention studies, but the impact on school attendance has varied. This review has systematically collected and evaluated evidence about the effects of menstrual hygiene interventions on schoolgirls. METHOD: A systematic search of the literature was done and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA statement). Both peer-reviewed journals and gray literature were searched using PubMed and Google Scholar. The search included individual, or cluster randomized controlled trials, and quasi-experimental studies, and covered the period from the date of indexing until January 3, 2023. RESULT: A review of sixteen trial studies showed that menstrual hygiene interventions have a positive effect on schoolgirls' school attendance, performance, and dropout rates, as well as on their menstrual knowledge, attitudes, practices, and emotional well-being. There was a low to medium risk of bias in most of the studies. Additionally, the literature overlooked the impact of interventions that involve parental and male engagement, interventions correcting community misperceptions about menstruation, and the impact of infrastructure improvements on water, sanitation, and hygiene. CONCLUSION: Interventions aimed at improving menstrual hygiene management can enhance schoolgirls' educational outcomes, and can improve their menstrual knowledge, attitudes, and practices by helping them manage their periods more effectively. Most interventions have focused on the provision of menstrual products and menstrual education but have neglected improvements in the physical environment at home and school and the social norms surrounding menstruation. Trial studies should take a holistic approach that considers the total socio-cultural environment in which menstrual hygiene management takes place, thus enabling stakeholders and policymakers to develop sustainable, long-term solutions to these problems.

Prevalence and factors associated with unmet need for menstrual hygiene management in six countries in Sub-Saharan Africa: A multilevel analysis.

BACKGROUND: Menstruation is a normal biological process experienced by more than 300 million women globally every day. Women require clean menstrual absorbents that can be changed as often as needed in a private and safe place with proper hygiene and disposal facilities. These needs must be met consistently throughout the duration of the menstrual cycle. Access to menstrual needs is crucial for women's health, wellbeing, and dignity. This study assessed the prevalence and factors associated with unmet need for menstrual hygiene management (MHM) in Ethiopia, Kenya, Uganda, Burkina Faso, Ghana, and Niger. METHODS: We used data from the Performance Monitoring for Action (PMA) 2020 surveys. We defined the unmet need for MHM as the "lackof resources, facilities and supplies for MHM." Sample characteristics were summarised using frequencies and percentages, while prevalence was summarised using proportions and their respective confidence intervals (CI). Factors associated with unmet need for MHM were assessed using multilevel logistic regression models. RESULTS: The study included 18,048 women of reproductive age from the six countries. The prevalence of unmet need for MHM was highest in Burkina Faso (74.8%), followed by Ethiopia (69.9%), Uganda (65.2%), Niger (57.8%), Kenya (53.5%), and lowest in Ghana (34.2%). Unmet need for MHM was consistently higher among uneducated and multiparous women, those who reused MHM materials, practiced open defecation, and lived in rural areas across all six countries. The odds of unmet need for MHM were higher among younger women under 35 years, unmarried women, those with lower education levels, and those from poorer households. Similarly, the reuse of MHM materials, use of shared or non-improved toilet facilities, and open defecation increased the odds of unmet need for MHM. In contrast, the presence of handwashing facilities reduced the odds of unmet need for MHM. CONCLUSION: More than half of the women in five of the six countries have an unmet need for MHM, with significantly higher odds among younger women, those with low wealth status, the unmarried, and those with inadequate access to sanitary facilities. This study highlights the state of period poverty in Sub-Saharan Africa. Efforts to end period poverty should consider MHM needs as an integrated whole, as addressing each need in isolation is insufficient.

Menstrual cup adoption among reproductive age women in India: a systematic review and meta-analysis.

This systematic review and meta-analysis aim to synthesize the information on menstrual cup adoption among reproductive-age women in India. A comprehensive search was conducted in four databases following PRISMA 2020 guidelines. A total of 18 articles were included in this review. The findings of the studies were described narratively, and meta-analysis and sensitivity analysis were also performed. The pooled prevalence of knowledge regarding menstrual cups among women in the included studies was 35 percent (CI: 0.23-.49). Just 5 percent (CI: 0.02-0.12) of women use menstrual cups. Only 24 percent (CI: 0.17-0.33) of the women who used menstrual cups reported leakage as one of the key barriers or issues to menstrual cup use. Nevertheless, 62 percent (CI: 0.42-0.78) of non-users have a pooled prevalence expressing willingness to use in the future. The price was found to be both a motivating and discouraging factor for using menstruation cups. Currently, menstrual cup use among Indian women and girls is very low. However, user reviews suggest that menstrual cups are an appealing and safer replacement for conventional period supplies. To fully realize the potential of menstruation cups, significant education, and awareness efforts are required to ensure proper usage. Furthermore, initiatives to lower the initial cost of menstruation cups are critical.

Understanding period product use among young women in rural and urban India from a geospatial perspective.

Ensuring proper menstrual hygiene management remains a significant challenge for young women in India. The term "exclusive use of hygienic period products during menstruation" refers to relying solely on period products like sanitary pads, tampons, or menstrual cups. Poor menstrual hygiene practices not only increase the risk of reproductive tract infections but also lead to various negative health outcomes, including discomfort and potential complications. This study explores factors associated with the exclusive use of period products during menstruation aged 15-24, investigates geographic disparities, examines rural-urban gaps, and assesses inequality in India. Utilizing data from the fifth National Family Health Survey (NFHS-5), responses from 2,41,180 women aged 15 to 24 were analysed using logistic regression and multivariate decomposition analyses to explore socioeconomic predictors. Moran's I statistics also assessed spatial dependency, while Lorenz curves and Gini coefficients measured inequality. Quintile and LISA maps visualized regional disparities. The study found that 76.15% of women in India reported exclusive use of hygienic period products during menstruation. Rural areas reported a lower percentage of exclusive use of hygienic period products (72.32%) during menstruation compared to urban areas (89.37%). Key factors associated with the exclusive use of hygienic period products among 15-24-year-old women in India include age, education, place of residence, wealth, access to media, and healthcare discussions. Geographically, central districts exhibited the lowest coverage (< 65%), while the Southern region reported the highest (> 85). The GINI coefficient of 0.39 highlighted moderate inequality in distribution. Decomposition analysis revealed that household wealth contributed 49.25% to rural-urban differences, followed by education (13.41%), media access (7.97%), and region (4.97%). This study highlights significant regional disparities and low utilization of hygienic period products among young women in India, particularly in central districts. Policymakers should prioritize interventions targeting these regions, addressing socio-economic disparities. Strategies to promote education, improve media access, and enhance household wealth can facilitate menstrual hygiene adoption. Initiatives to reduce sanitary napkin costs and increase accessibility, particularly in rural areas, are crucial to mitigating geographical disparities nationwide.

Causal association of menstrual reproductive factors on the risk of osteoarthritis: A univariate and multivariate Mendelian randomization study.

OBJECTIVE: Several observational studies have revealed a potential relationship between menstrual reproductive factors (MRF) and osteoarthritis (OA). However, the precise causal relationship remains elusive. This study performed Mendelian randomization (MR) to provide deeper insights into this relationship. METHODS: Utilizing summary statistics of genome-wide association studies (GWAS), we conducted univariate MR to estimate 2 menstrual factors (Age at menarche, AAM; Age at menopause, AMP) and 5 reproductive factors (Age at first live birth, AFB; Age at last live birth, ALB; Number of live births, NLB; Age first had sexual intercourse, AFSI; Age started oral contraceptive pill, ASOC) on OA (overall OA, OOA; knee OA, KOA and hip OA, HOA). The sample size of MRF ranged from 123846 to 406457, and the OA sample size range from 393873 to 484598. Inverse variance weighted (IVW) method was used as the primary MR analysis methods, and MR Egger, weighted median was performed as supplements. Sensitivity analysis was employed to test for heterogeneity and horizontal pleiotropy. Finally, multivariable MR was utilized to adjust for the influence of BMI on OA. RESULTS: After conducting multiple tests (P<0.0023) and adjusting for BMI, MR analysis indicated that a lower AFB will increase the risk of OOA (odds ratio [OR] = 0.97, 95% confidence interval [CI]: 0.95-0.99, P = 3.39×10-4) and KOA (OR = 0.60, 95% CI: 0.47-0.78, P = 1.07×10-4). ALB (OR = 0.61, 95% CI: 0.45-0.84, P = 2.06×10-3) and Age AFSI (OR = 0.66, 95% CI: 0.53-0.82, P = 2.42×10-4) were negatively associated with KOA. In addition, our results showed that earlier AMP adversely affected HOA (OR = 1.12, 95% CI: 1.01-1.23, P = 0.033), and earlier ASOC promote the development of OOA (OR = 0.97, 95% CI: 0.95-1.00, P = 0.032) and KOA (OR = 0.58, 95% CI: 0.40-0.84, P = 4.49×10-3). ALB (OR = 0.98, 95% CI: 0.96-1.00, P = 0.030) and AFSI (OR = 0.98, 95% CI: 0.97-0.99, P = 2.66×10-3) also showed a negative association with OOA but they all did not pass multiple tests. The effects of AAM and NLB on OA were insignificant after BMI correction. CONCLUSION: This research Certificates that Early AFB promotes the development of OOA, meanwhile early AFB, ALB, and AFSI are also risk factors of KOA. Reproductive factors, especially those related to birth, may have the greatest impact on KOA. It provides guidance for promoting women's appropriate age fertility and strengthening perinatal care.

Diagnostic Value of Menstrual Blood Lipidomics in Endometriosis: A Pilot Study.

Endometriosis is a prevalent chronic inflammatory disease characterized by a considerable delay between initial symptoms and diagnosis through surgery. The pressing need for a timely, non-invasive diagnostic solution underscores the focus of current research efforts. This study examines the diagnostic potential of the menstrual blood lipidome. The lipid profile of 39 samples (23 women with endometriosis and 16 patients in a control group) was acquired using reverse-phase high-performance liquid chromatography-mass spectrometry with LipidMatch processing and identification. Profiles were normalized based on total ion counts. Significant differences in lipids were determined using the Mann-Whitney test. Lipids for the diagnostic model, based on logistic regression, were selected using a combination of variance importance projection filters and Akaike information criteria. Levels of ceramides, sphingomyelins, cardiolipins, triacylglycerols, acyl- and alkenyl-phosphatidylethanolamines, and alkenyl-phosphatidylcholines increased, while acyl- and alkyl-phosphatidylcholines decreased in cases of endometriosis. Plasmenylphosphatidylethanolamine PE P-16:0/18:1 and cardiolipin CL 16:0_18:0_22:5_22:6 serve as marker lipids in the diagnostic model, exhibiting a sensitivity of 81% and specificity of 85%. The diagnostic approach based on dried spots of menstrual blood holds promise as an alternative to traditional non-invasive methods for endometriosis screening.

Defining Vaginal Community Dynamics: daily microbiome transitions, the role of menstruation, bacteriophages, and bacterial genes.

BACKGROUND: The composition of the vaginal microbiota during the menstrual cycle is dynamic, with some women remaining eu- or dysbiotic and others transitioning between these states. What defines these dynamics, and whether these differences are microbiome-intrinsic or mostly driven by the host is unknown. To address this, we characterized 49 healthy, young women by metagenomic sequencing of daily vaginal swabs during a menstrual cycle. We classified the dynamics of the vaginal microbiome and assessed the impact of host behavior as well as microbiome differences at the species, strain, gene, and phage levels. RESULTS: Based on the daily shifts in community state types (CSTs) during a menstrual cycle, the vaginal microbiome was classified into four Vaginal Community Dynamics (VCDs) and reported in a classification tool, named VALODY: constant eubiotic, constant dysbiotic, menses-related, and unstable dysbiotic. The abundance of bacteria, phages, and bacterial gene content was compared between the four VCDs. Women with different VCDs showed significant differences in relative phage abundance and bacterial composition even when assigned to the same CST. Women with unstable VCDs had higher phage counts and were more likely dominated by L. iners. Their Gardnerella spp. strains were also more likely to harbor bacteriocin-coding genes. CONCLUSIONS: The VCDs present a novel time series classification that highlights the complexity of varying degrees of vaginal dysbiosis. Knowing the differences in phage gene abundances and the genomic strains present allows a deeper understanding of the initiation and maintenance of permanent dysbiosis. Applying the VCDs to further characterize the different types of microbiome dynamics qualifies the investigation of disease and enables comparisons at individual and population levels. Based on our data, to be able to classify a dysbiotic sample into the accurate VCD, clinicians would need two to three mid-cycle samples and two samples during menses. In the future, it will be important to address whether transient VCDs pose a similar risk profile to persistent dysbiosis with similar clinical outcomes. This framework may aid interdisciplinary translational teams in deciphering the role of the vaginal microbiome in women's health and reproduction. Video Abstract.
