    The American Academy of Pediatrics and American College of Obstetricians and Gynecologists have identified the menstrual cycle as essential in assessing overall health of adolescent girls. Menses should be considered a "vital sign" and documentation of last menstrual period (LMP) is recommended at every patient encounter. The aim of this study was to estimate and compare LMP documentation among adolescent and pediatric health care providers. A retrospective cohort study identified a random sample of 50 female patients seen in the general pediatrics (PEDS), adolescent medicine (AM), and pediatric and adolescent gynecology (PAG) ambulatory clinics at Phoenix Children's Hospital between January 1, 2016 and March 31, 2016. Rates of LMP documentation were compared between clinics using the Pearson χ 2 test. Multivariable logistic regression analyses quantified the association of clinic and LMP documentation, with adjustments for visit reason, provider gender, and age at presentation. Rates of LMP documentation were 100% for adolescent gynecologists, but significantly lower for general pediatricians (14%) and AM (60%) providers (P < .0001). These findings were confirmed in multivariable analyses (PAG vs PEDS: odds ratio [OR], 280; 95% confidence interval [CI], 32-2331; PAG vs AM: OR, 34; 95% CI, 4.4-270; AM vs PEDS: OR, 3.8; 95% CI, 1.3-11.0). Adolescent gynecologists document LMP routinely. In contrast, LMP documentation rates in AM, and especially in PEDS, were significantly lower. Quality improvement methods such as incorporation of an LMP section into the vitals portion of an electronic medical record could help improve rates of compliance.

    Full Text Available The aim of this study was to assess the validity of the last menstrual period (LMP estimate in determining pre and post-term birth rates, in a prenatal cohort from two Brazilian cities, São Luís and Ribeirão Preto. Pregnant women with a single fetus and less than 20 weeks' gestation by obstetric ultrasonography who received prenatal care in 2010 and 2011 were included. The LMP was obtained on two occasions (at 22-25 weeks gestation and after birth. The sensitivity of LMP obtained prenatally to estimate the preterm birth rate was 65.6% in São Luís and 78.7% in Ribeirão Preto and the positive predictive value was 57.3% in São Luís and 73.3% in Ribeirão Preto. LMP errors in identifying preterm birth were lower in the more developed city, Ribeirão Preto. The sensitivity and positive predictive value of LMP for the estimate of the post-term birth rate was very low and tended to overestimate it. LMP can be used with some errors to identify the preterm birth rate when obstetric ultrasonography is not available, but is not suitable for predicting post-term birth.

    The clinical predictors of aromatase inhibitor-related arthralgia (AIA), a drug-related adverse reaction of aromatase inhibitors (AIs), remain unclear. AIA was prospectively surveyed every 4 months in 328 postmenopausal breast cancer patients administered a non-steroidal AI (anastrozole). Various clinicopathological parameters were recorded and analyzed (chi-square test, Fisher's exact test and logistic regression analysis). The mean observation period was 39.9 months. AIA manifested in 114 patients (34.8%), with peaks of onset at 4 (33.7%) and 8 months (11.4%) after starting AI administration. Some cases manifested even after 13 months. AIA tended to occur in younger patients (incidences of 46.3%, 37.4% and 28.0% for ages of 65 years, respectively (p = 0.063)) and decreased significantly with the age at menarche (53.3%, 35.3% and 15.4% for 15 years, respectively (p = 0.036)). The incidences were 45.1%, 46.3 and 25.1% for the time since the last menstrual period (LMP) 10 years, being significantly lower at > 10 years (p time since LMP > 10-year group versus the time since LMP became shorter ( 10 years since LMP. When the time since LMP was short, the onset of AIA was significantly earlier after starting AI administration.

    To determine whether pregnancy status, gynaecological history, date of last menstrual period and contraceptive use are documented in emergency female admissions of reproductive age admitted to general surgery. This is a retrospective study. This study was conducted in the United Kingdom. Females of reproductive age (12-50 years) admitted as an emergency to general surgery with abdominal pain were considered in this study. Retrospective analysis of medical notes of emergency female admissions with abdominal pain between January and September 2012. We recorded whether a pregnancy test result was documented (cycle 1). Results were analysed and a prompt added to the medical clerk-in document. We re-audited (cycle 2) between January and June 2013 looking for improvement. Documented pregnancy status within 24 h of admission and prior to any surgical intervention. 100 case notes were reviewed in stage 1. 30 patients (30 %) had a documented pregnancy status. 32 (32 %), 25 (25 %) and 29 (29 %) had a documented gynaecology history, contraceptive use and date of last menstrual period (LMP), respectively. 24 patients underwent emergency surgery, 6 (25 %) had a documented pregnancy status prior to surgery. Of 50 patients reviewed in stage 2, 37 (75.0 %) had a documented pregnancy status (p contraceptive use (p < 0.0001) documented. 40 patients (80 % had a documented LMP (p < 0.0001). 7 patients required surgery, of whom 6 (85.7 %) had a documented pregnancy test prior to surgery (p = 0.001). All pregnancy tests were negative. A simple prompt in the surgical admission document has significantly improved the documentation of pregnancy status and gynaecological history in our female patients, particularly in those who require surgical intervention. A number of patient safety concerns were addressed locally, but require a coordinated, interdisciplinary discussion and a national guideline. A minimum standard of care, in females of reproductive age, should include mandatory objective

    Purpose: To determine whether the phase of menstrual cycle at the time of MR-guided focused ultrasound surgery (MRgFUS) treatment for uterine leiomyomas affects treatment outcome. Methods: We enrolled all patients participating in a prospective phase III clinical trial from our center who completed 6 months of clinical and imaging follow-up. Patients with irregular cycles and those on oral contraceptives were excluded. Data prospectively documenting the date of the last menstrual period (LMP) at the time of treatment, length and duration of cycle, and raw symptom severity score (SSS) from the Uterine Fibroid Symptom and Quality of Life questionnaire, at baseline and 6 months were collected. Proliferative phase patients were determined retrospectively as those who were treated within less than 14 days from LMP; secretory phase patients were classified as those who were treated greater than 14 days from LMP. Results: A total of 58 patients were enrolled. There was no significant difference in the mean SSS at baseline and mean SSS at 6 months between patients treated in the proliferative versus secretory phase of the cycle. No significant difference in the SSS change from baseline to 6 months was seen between the two groups. Conclusions: Menstrual cycle phase does not influence MRgFUS treatment outcome. Symptomatic improvement occurs with treatment during either phase of the menstrual cycle. Thus, the scheduling of MRgFUS treatment need not be based upon the phase of the menstrual cycle

    The aim of this study was to investigate the efficacy of 50% glycolic acid peeling performed at different phases of menstruation on acne. This study included 30 patients with mild-to-moderate acne. Those with regular menstrual cycles and no history or laboratory evidence of hormonal pathology, hirsutism were selected. Thirty patients were divided in three groups. The first group received peeling applications in the first 7 days of menstruation; the second group received the peel between 10 and 14 days; and the third group received the peel during the last 10 days of menstruation. The 30 female patients included in study. All patients' menstrual cycles were regular. All groups were homogenous in terms of initial acne severity scores. Acne severity scores decreased in all groups after 3 months of therapy; statistically significant differences were achieved only in the second group. The results of our study suggest that chemical peeling administered during ovulation provides the most significant benefit for acne lesions. Ovulation is the period when estrogen reaches its highest level. Estrogen decreases sebum production through different mechanisms. The beneficial effects of estrogen on acne and healing in combination with those of chemical peeling may cause synergistic therapeutic effects with pronounced results.

    Variations in steroid hormone receptor contents throughout age and menopausal periods define three breast carcinoma groups: younger pre-menopausal carcinomas (aged up to 45), middle-aged carcinomas (aged up to 45), middle-aged carcinomas (pre-, peri-, and postmenopausal aged 45-59) and older postmenopausal carcinomas (aged over 59). Age-related steroid hormone receptor contents within pre-menopausal and postmenopausal carcinoma groups are characterized by the important increase of both receptor contents, while menopausal-related steroid hormone receptor contents within middle-aged carcinoma group (aged 45-59) are characterized by the important decrease of progesterone receptor content and estrogen receptor functionality. No variations in steroid hormone receptor contents throughout menstrual cycle within the follicular and the luteal phases were obtained. The important cycle within the follicular and the luteal phases were obtained. The important decrease of estrogen receptor content in the mid-cycle phase versus the peri-menstrual phase was found. Variations in steroid hormone receptor contents throughout age and menopausal periods, as well as throughout menstrual cycle could nod be associated with variations in the blood steroid hormone concentrations. However, important association between steroid hormone receptor contents and the blood steroid hormone concentrations was found within the luteal phase carcinoma group and within older postmenopausal carcinoma group. It is interesting that within carcinoma group with the highest concentration of progesterone, progesterone receptor content increases with an increase of the ration of estradiol and progesterone blood concentrations, while within carcinoma group with the lowest steroid hormone concentration and the highest content of estrogen receptor content, estrogen receptor content decreases with an increase of either the blood estradiol concentration or the ratio of the blood estradiol and progesterone blood

    Full Text Available Abstract Background When an ultrasound-based estimate of gestational age (GA is less (greater than an estimate based on a definite last menstrual period, the fetus may grow slower (faster than average. While the association between these discrepancies in GA estimates and adverse perinatal outcomes has been examined extensively, there is scant evidence about long-term effects, such as child neurodevelopment. Methods Using data from a prospective cohort study titled, NICHD Study of Successive Small-for-Gestational Age Births, we examined if GA discrepancies in early second trimester of pregnancy (17 weeks’ gestation are associated with: (1 impaired motor and mental function at 13 months (measured using Bayley Scales of Infant Development (Bayley, and (2 impaired cognitive development at five years (assessed by Wechsler Preschool and Primary Scale of Intelligence – Revised Intelligence Quotient (WPPSI-R in the infant. The study population consisted of 572 (30% of the overall sample of 1,945 women who presented for prenatal care in Norway and Sweden between 1986 and 1988. Results Our results showed that GA discrepancies in early second trimester are significantly associated with birthweight. We found no significant relationship, however, with the Bayley development scores at 13 months and with the WPPSI-R IQ measures at five years. Conclusions GA discrepancies at 17 weeks’ gestation are not associated child neurodevelopment. These discrepancies do, however, relate to birthweights, providing a basis for detecting fetal growth patterns early in the second trimester of pregnancy. Our study, however, was unable to evaluate the impact of first-trimester discrepancies on impaired neurodevelopment in the infant.

    Epstein-Barr virus (EBV) is related to a variety of malignant tumors, and its encoded protein, latent membrane protein 2 (LMP2), is an effective target antigen that is widely used to construct vector vaccines. However, the model cells carrying LMP2 have still not been established to assess the oncolytic effect of LMP2-related vaccines at present. In this study, TC-1-GLUC-LMP2 tumor cells were constructed as target cells to evaluate the anti-tumor effects of LMP2-assosiated vaccines. The results showed that both LMP2 and Gaussia luciferase (GLuc) genes could be detected by polymerase chain reaction (PCR) and reverse transcription-polymerase chain reaction (RT-PCR) in TC-1-GLUC-LMP2 cells. Western blot results showed that the LMP2 and Gaussia luciferase proteins were stably expressed in tumor cells for at least 30 generations. We mixed 5 × 104 LMP2-specific mouse splenic lymphocytes with 5 × 103 TC-1-GLUC-LMP2 target cells and found that the target cells were killed as the specific killing effect was obviously enhanced by the increased quantities of LMP2-peptide stimulated spleens. Furthermore, the tumor cells could not be observed in the mice inoculated TC-1-GLUC-LMP2 cells after being immunized with vaccine-LMP2, while the vaccine-NULL immunized mice showed that tumor volume gradually grew with increased inoculation time. These results indicated that the TC-1-GLUC-LMP2 cells stably expressing LMP2 and GLuc produced tumors in mice, and that the LMP2-specific cytotoxic T lymphocyte (CTL) effectively killed the cells in vitro and in vivo, suggesting that TC-1-GLUC-LMP2 cells can be used as model cells to assess the immune and antitumor effects of LMP2-related vaccines.

    In order to get further information on the effects of ulipristal acetate (UPA) upon the process of decidualization of endometrium, a functional analysis of the differentially expressed genes in endometrium (DEG) from UPA treated-versus control-cycles of normal ovulatory women was performed. A list of 1183 endometrial DEG, from a previously published study by our group, was submitted to gene ontology, gene enrichment and ingenuity pathway analyses (IPA). This functional analysis showed that decidualization was a biological process overrepresented. Gene set enrichment analysis identified LIF, PRL, IL15 and STAT3 among the most down-regulated genes within the JAK STAT canonical pathway. IPA showed that decidualization of uterus was a bio-function predicted as inhibited by UPA. The results demonstrated that this selective progesterone receptor modulator, when administered during the periovulatory phase of the menstrual cycle, may affect the molecular mechanisms leading to endometrial decidualization in response to progesterone during the period of maximum embryo receptivity.

    2011-06-01

    Full Text Available Abstract Background The onset of menstruation is a landmark event in the life of a young woman. Yet the complications and challenges that can accompany such an event have been understudied, specifically in resource-poor settings. As interventions aim to improve female attendance in schools, it is important to explore how menstruation is perceived and navigated by girls in the school setting. This research conveys rural Kenyan schoolgirls' perceptions and practices related to menstruation Methods Data were collected at six rural schools in the Nyanza Province of Western Kenya. Using focus group discussions, in-depth interviews, and field notes from observations, researchers collected information from 48 primary schoolgirls and nine teachers. Systematic analysis began with a reading of transcripts and debriefing notes, followed by manual coding of the narratives. Results Focus group discussions became opportunities for girls to share thoughts on menstruation, instruct one another on management practices and advise one another on coping mechanisms. Girls expressed fear, shame, distraction and confusion as feelings associated with menstruation. These feelings are largely linked to a sense of embarrassment, concerns about being stigmatized by fellow students and, as teachers explained, a perception that the onset of menstruation signals the advent of a girl's sexual status. Among the many methods for managing their periods, girls most frequently said they folded, bunched up or sewed cloth, including cloth from shirts or dresses, scraps of old cloth, or strips of an old blanket. Cloth was reported to frequently leak and cause chafing, which made school attendance difficult particularly as the day progressed. Attitudes and practices of girls toward menstruation have been arranged into personal, environmental and behavioural factors. Conclusion Further research on menstrual management options that are practical, sustainable and culturally acceptable

In these malignancies, EBV latent membrane protein 1 (LMP1) and LMP2A provide infected B cells with surrogate CD40 and B-cell receptor growth and survival signals. To gain insights into their synergistic in vivo roles in germinal center (GC) B cells, from which most EBV-driven lymphomas arise, we generated a mouse model with conditional GC B-cell LMP1 and LMP2A coexpression. LMP1 and LMP2A had limited effects in immunocompetent mice. However, upon T- and NK-cell depletion, LMP1/2A caused massive plasmablast outgrowth, organ damage, and death. RNA-sequencing analyses identified EBV oncoprotein effects on GC B-cell target genes, including up-regulation of multiple proinflammatory chemokines and master regulators of plasma cell differentiation. LMP1/2A coexpression also up-regulated key HL markers, including CD30 and mixed hematopoietic lineage markers. Collectively, our results highlight synergistic EBV membrane oncoprotein effects on GC B cells and provide a model for studies of their roles in immunosuppression-related lymphoproliferative diseases.

    The aim of this study was to examine the relation between increased physical activity and menstrual disorders in adolescent female volleyball players. The study was conducted on 210 Polish female volleyball players, aged 13-17 years, the authorship questionnaire was used. The results of the study showed that irregular menstruation occurred in 19% of girls, spotting between menstrual periods in 27% and heavy menstruation was reported in 33% of girls. Out of all volleyball female players participating in the study, 94 girls (45%) declared absence of menstrual periods after regular cycles. Statistical analysis showed that the more training hours per week, the bigger probability of the occurrence of irregular menstruation. It was concluded that the number of hours of volleyball training per week affects regularity of menstrual cycles in female volleyball players. The absence of menstruation might be caused by the duration of training per week or years of training.

    Full Text Available Objective. This study is performed to obtain objective diagnostic indicators associated with menstrual pain using pulse wave analysis. Methods. Using a pulse diagnostic device, we measured the pulse waves of 541 women aged between 19 and 30 years, placed in either an experimental group with menstrual pain (n=329 or a control group with little or no menstrual pain (n=212. Measurements were taken during both the menstrual and nonmenstrual periods, and comparative analysis was performed. Results. During the nonmenstrual period, the experimental group showed a significantly higher value in the left radial artery for the radial augmentation index (RAI (p=0.050 but significantly lower values for pulse wave energy (p=0.021 and time to first peak from baseline (T1 (p=0.035 in the right radial artery. During the menstrual period, the experimental group showed significantly lower values in the left radial artery for cardiac diastole and pulse wave area during diastole and significantly higher values for pulse wave area during systole, ratio of systolic phase to the full heartbeat, and systolic-diastolic ratio. Conclusion. We obtained indicators of menstrual pain in women during the menstrual period, including prolonged systolic and shortened diastolic phases, increases in pulse wave energy and area of representative pulse wave, and increased blood vessel resistance.

    Full Text Available BACKGROUND Menstruation is a vital part of the reproductive health of a woman. There is evident neglect of problems related to menstruation especially in young girls and they are lacking scientific knowledge regarding menstruation. The study was undertaken with the objective to assess the prevalence & patterns of menstrual problems, knowledge, belief, restrictions, menstrual hygiene and treatment seeking practice among college going unmarried girls of Chandigarh. MATERIALS AND METHODS A stratified multistage random sampling design was adopted for selection of participants from the selected colleges of Chandigarh. A total of 1000 girls who had attained menarche were selected. Information was collected through personal interviews conducted in privacy using semi -structured survey schedule. RESULTS The mean age of menarche was ± 13.89 years. Prior knowledge regarding menses was reported by 82.6% girls and 56.9% girls reported mother as the first source of information followed by 21.6% friends. 86.1% have regular menstrual history 86.8% of the respondents experienced pre menstrual syndrome while overall prevalence of menstrual problem in the present study was found 68.4%. Abdominal pain was the most common menstrual problem reported by 51.3% of participants having menstrual problems. 47.7% girls did not visit holy places during periods. 95.5% preferred sanitary napkins as menstrual absorbent. Treatment seeking behavior of the girls was poor and only about 34.9% of girls having menstrual problems approached for treatment. 72.4% of respondents were aware of emergency contraceptives. CONCLUSION The study revealed that there was an inappropriate knowledge and hygiene practice due to various Misconceptions, beliefs and taboos among college girls regarding menstruation. Reproductive health education in the school curriculum should be introduced for improving awareness regarding menstrual care practices.

    Management of protein homeostasis by the ubiquitin-proteasome system is critical for atherosclerosis development. Recent studies showed controversial results on the role of immunoproteasome (IP) subunit β5i/LMP7 in maintenance of protein homeostasis under cytokine induced oxidative stress. The present study aimed to investigate the effect of β5i/LMP7-deficiency on the initiation and progression of atherosclerosis as a chronic inflammatory, immune cell driven disease. LDLR -/- LMP7 -/- and LDLR -/- mice were fed a Western-type diet for either 6 or 24 weeks to induce early and advanced stage atherosclerosis, respectively. Lesion burden was similar between genotypes in both stages. Macrophage content and abundance of polyubiquitin conjugates in aortic root plaques were unaltered by β5i/LMP7-deficiency. In vitro experiments using bone marrow-derived macrophages (BMDM) showed that β5i/LMP7-deficiency did not influence macrophage polarization or accumulation of polyubiquitinated proteins and cell survival upon hydrogen peroxide and interferon-γ treatment. Analyses of proteasome core particle composition by Western blot revealed incorporation of standard proteasome subunits in β5i/LMP7-deficient BMDM and spleen. Chymotrypsin-, trypsin- and caspase-like activities assessed by using short fluorogenic peptides in BMDM whole cell lysates were similar in both genotypes. Taken together, deficiency of IP subunit β5i/LMP7 does not disturb protein homeostasis and does not aggravate atherogenesis in LDLR -/- mice.

    To study the effect of a short period of war on the menstrual cycles of exposed women. Six months after a 16-day war, women in exposed villages aged 15-45 years were asked to complete a questionnaire relating to their menstrual history at the beginning, 3 months after, and 6 months after the war. A control group, not exposed to war, was also interviewed. The data collected were analyzed to estimate the effect of war on three groups of women: those who stayed in the war zone for 3-16 days (Group A), those who were displaced within 2 days to safer areas (Group B), and women not exposed to war or displacement (Group C-control). More than 35% of women in Group A and 10.5% in Group B had menstrual aberrations 3 months after the cessation of the war. These percentages were significantly different from each other and from that in Group C (2.6%). Six months after the war most women regained their regular menstrual cycles with the exception of 18.6% in Group A. We found a short period of war, acting like an acute stressful condition, resulted in menstrual abnormalities in 10-35% of women and is probably related to the duration of exposure to war. This might last beyond the war time and for more than one or two cycles. In most women the irregular cycles reversed without any medical intervention. II.

    Menstruation coupled periodic bleeding from the blood vessels, at the time of shedding of the uterine mucosa has directed interest, more especially in the haematological changes during different phases of menstrual cycle. Methods: The present study was carried out on 30 healthy female medical students in the age group of 18 to 23 years with the normal menstrual cycle of 30 +- 3 days. The various haematological parameter and electrocardiography were studied on the second, eleventh, fourteenth and twenty second day of menstrual cycle. Result: The study reveals that the total leukocyte count and total platelet count significantly increased (p<0.001) around mid cycle, however total eosinophil count significantly decreased (p<0.05) during the same period. Differential leukocyte count, bleeding time, clotting time, heart rate, P-R interval and Q-T interval did not show any significant change during different phases of menstrual cycle, although some mild changes were observed. Conclusion: This study was a moderate attempt to determine regular variation in the different haematological parameters and ECG during the different phases of menstrual cycle in normal healthy females and evaluate conflicting reports on the subjects.

    Requests for assistance in menstrual management and menstrual suppression are a common, emotive and sometimes controversial aspect of adolescent disability care. To review the uptake and outcomes of menstrual suppression among adolescent patients with developmental delay. A retrospective review of the medical records of adolescent females with intellectual disability referred for menstrual management to the Paediatric and Adolescent Gynaecology Clinic, Children's Hospital at Westmead, Sydney, for the three-year period between January 1, 2010 and January 1, 2013. Eighty adolescent patients with developmental delay were identified. A third (n = 28) of the patients were pre-menarcheal at first review with parent/caregivers seeking anticipatory advice. Of the post-menarcheal patients, the median age of menarche was 12 years (range 10-15 years). First and second line interventions were documented as were reasons for change where applicable. The combined oral contraceptive pill (COCP) was the most frequently used therapy (67%), and 19 patients in total had a levonorgestrel releasing intrauterine system (LNG-IUS) inserted (31%). Our study population differs from similar previously published groups in the marked absence of the use of depot medroxyprogesterone acetate or the subdermal etonogestrel releasing device. As a paediatrician, it is important to address menstrual management issues and allay caregiver concerns with appropriate advice. Our study supports the use of the COCP as sound first line management in achieving menstrual suppression. The LNG-IUS appears to be a favourable second line option. Further investigation into longer-term outcomes and potential complications of device insertion is recommended. © 2017 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Menstrual and peripheral blood samples were collected from 19 regularly cycling women on days 1-3 of the menstrual cycle. Menstrual samples were collected with a soft silicone rubber menstrual cup. Hematocrit, PRL, LH, FSH, estradiol (E2), and progesterone (P4) were measured in all samples. Validation studies were carried out for RIAs of PRL, LH, and FSH in menstrual plasma. The menstrual plasma PRL level was significantly higher than its peripheral blood level on day 1 (63.3 +/- 14.7 and 12.1 +/- 2.9 micrograms/L, respectively; t = 3.331; P less than 0.01), and menstrual PRL was significantly higher on day 1 than on day 2 (t = 3.340; P less than 0.01). There was a strong negative correlation between log menstrual PRL concentration and time of onset of menstruation (r = -0.596; P less than 0.01). Menstrual plasma FSH levels were significantly lower than peripheral levels on each of days 1-3 (day 1:t = 4.787; P less than 0.001), and there was a significant positive correlation between menstrual and peripheral levels (r = 0.607; P less than 0.01). By contrast, menstrual plasma LH was significantly higher than the peripheral level on days 1 and 2 (day 1:t = 3.105; day 2:t = 3.180; P less than 0.01), with no correlation between menstrual and peripheral levels. Menstrual E2 was slightly lower than and significantly positively correlated with peripheral E2 (r = 0.646; P less than 0.01). Menstrual P4 was lower than but showed no correlation with peripheral levels. As expected, the menstrual blood hematocrit was less than 0.20 and highly significantly lower than that of peripheral venous blood. These results suggest that PRL is released in substantial amounts from secretory endometrium into the menstrual flow during the first day of menstrual breakdown. LH may also be released in small amounts from menstrual endometrium, while menstrual FSH, E2, and P4 probably arise entirely from the peripheral circulation.

    Intracellular fragments of latent phase protein LMP1 of Epstein-Barr virus, denoted as CTAR1/2/3, can trigger a variety of cell cascades and contribute to the transforming potential of the virus. Generation of recombinant proteins CTAR1/2/3 is expected to yield more ample data on functional and immunogenic characteristics of LMP1. We created genetic constructs for prokaryotic expression of LMP1 CTAR fragments and selected optimal conditions for their production and purification. Using a new library of LMP1 CTAR fragments, we carried out epitope mapping of a diagnostic anti-LMP1 antibody S12. Analysis of polyclonal serum antibodies from mice immunized with full-length LMP1 confirmed immunogenicity of CTAR elements comparable with that of full-length protein.

    Full Text Available An EBV-specific cellular immune response is associated with the control of EBV-associated malignancies and lymphoproliferative diseases, some of which have been successfully treated by adoptive T cell therapy. Therefore, many methods have been used to measure EBV-specific cellular immune responses. Previous studies have mainly used autologous EBV-transformed B-lymphoblastoid cell lines (B-LCLs, recombinant viral vectors transfected or peptide pulsed dendritic cells (DCs as stimulators of CD8(+ and CD4(+ T lymphocytes. In the present study, we used an interferon-γ (IFN-γ enzyme-linked immunospot (ELISPOT assay by using isolated CD8(+ and CD4(+ T cells stimulated with mRNA-transfected DCs. The frequency of latent membrane protein 1 (LMP1-specific IFN-γ producing CD4(+ T cells was significantly higher than that of LMP2a. The frequency of IFN-γ producing CD4(+ T cells was significantly correlated with that of CD8(+ T cells in LMP1-specific immune responses (r = 0.7187, Pc < 0.0001. To determine whether there were changes in LMP1- or LMP2a-specific immune responses, subsequent peripheral blood mononuclear cells (PBMCs samples were analyzed. Significant changes were observed in 5 of the 10 donors examined, and CD4(+ T cell responses showed more significant changes than CD8(+ T cell responses. CD8(+ and CD4(+ T cells from EBV-seropositive donors secreted only the Th1 cytokines IFN-γ, TNF-α, and IL-2, while Th2 (IL-4 and Th17 (IL-17a cytokines were not detected. CD4(+ T cells secreted significantly higher cytokine levels than did CD8(+ T cells. Analysis of EBV-specific T cell responses using autologous DCs transfected with mRNA might provide a comprehensive tool for monitoring EBV infection and new insights into the pathogenesis of EBV-associated diseases.

    Full Text Available Myeloid-derived suppressor cells (MDSCs are expanded in tumor microenvironments, including that of Epstein-Barr virus (EBV-associated nasopharyngeal carcinoma (NPC. The link between MDSC expansion and EBV infection in NPC is unclear. Here, we show that EBV latent membrane protein 1 (LMP1 promotes MDSC expansion in the tumor microenvironment by promoting extra-mitochondrial glycolysis in malignant cells, which is a scenario for immune escape initially suggested by the frequent, concomitant detection of abundant LMP1, glucose transporter 1 (GLUT1 and CD33+ MDSCs in tumor sections. The full process has been reconstituted in vitro. LMP1 promotes the expression of multiple glycolytic genes, including GLUT1. This metabolic reprogramming results in increased expression of the Nod-like receptor family protein 3 (NLRP3 inflammasome, COX-2 and P-p65 and, consequently, increased production of IL-1β, IL-6 and GM-CSF. Finally, these changes in the environment of malignant cells result in enhanced NPC-derived MDSC induction. One key step is the physical interaction of LMP1 with GLUT1 to stabilize the GLUT1 protein by blocking its K48-ubiquitination and p62-dependent autolysosomal degradation. This work indicates that LMP1-mediated glycolysis regulates IL-1β, IL-6 and GM-CSF production through the NLRP3 inflammasome, COX-2 and P-p65 signaling pathways to enhance tumor-associated MDSC expansion, which leads to tumor immunosuppression in NPC.

    Full Text Available Abstract Background LMP-420 is a boronic acid-containing purine nucleoside analogue that transcriptionally inhibits TNF production but is non-cytotoxic to TNF-producing cells. Methods This study investigated the efficacy of LMP-420 as an anti-inflammatory agent in acute and chronic colitis induced by oral administration of dextran sulfate sodium (DSS to mice and in chronic colitis following piroxicam administration to IL-10-deficient mice. The severity of colon inflammation was assessed histologically. TNF levels were measured by enzyme immunoassay. Results Administration of DSS for 7 days resulted in severe acute colitis that was associated with a marked increase in stool and colon tissue TNF levels. Initiation of therapy with intraperitoneal (i.p. LMP-420 on day 4 of DSS exposure decreased colonic TNF to near normal levels on day 7. However, neither i.p. nor oral treatment with LMP-420 affected the development or severity of acute DSS colitis. Initiation of LMP-420 therapy after 3 cycles of DSS administration to establish chronic colitis also had no effect on the severity of chronic colitis. Analysis of colonic TNF combined with longitudinal analysis of TNF and TNF receptor (TNF-RII levels in stool during the development of chronic DSS colitis demonstrated that the initially elevated colonic TNF levels returned to normal despite intense on-going inflammation in mice with chronic colitis. RAG-2-/- mice deficient in T and B cells also developed severe ongoing colitis in response to 3 cycles of DSS, but showed marked differences vs. wild type mice in stool TNF and TNF-RII in response to DSS exposure. Systemic and oral LMP-420 treatment for 16 days decreased colonic TNF levels in IL-10-deficient mice with chronic colitis, with a trend to decreased histologic inflammation for oral LMP-420. Conclusion These studies demonstrate that short-term treatment with a transcriptional inhibitor of TNF production can decrease systemic and local colonic levels

    Conclusion: The results of this study are comparable to those in other parts of the world. Adolescents should be encouraged to chart their menstrual periods from menarche onwards in order to focus their attention on when and how to seek medical advice. Health education on menstrual disorders targeting adolescents and including education on reproductive health in the school/university curriculum may assist in early detection of these disorders.

    A 20-year-old woman attended a genitourinary clinic with a retained vaginal Mooncup that she had inserted the night before. A Mooncup is one type of menstrual cup. On speculum examination the device was visualized high in the vagina and the cervix appeared firmly lodged within it. The physician experienced difficulty in retrieving the cup despite following product instructions. This case highlights a new adverse event with an increasingly used sanitation product. It is important that clinicians are familiar with the cup, its removal process and are able to counsel patients with retained devices on future correct placement.

    To validate the menstrual pictogram (superabsorbent polymer-c version) for Always Ultra-slim feminine towels containing superabsorbent polymers. Prospective, multicenter, evaluator-blinded study. Three gynecology research clinics in the United Kingdom. Women with self-perceived light, normal, or heavy menstrual periods who had not previously used a graphical method to assess their menstrual loss. One hundred twenty-two women were asked to complete the menstrual pictogram throughout two menstrual periods and collect their feminine towels for measurements of menstrual blood loss (MBL) by the alkaline hematin method and total menstrual fluid loss (MFL) by fluid weight. Agreement of menstrual pictogram MBL and MFL scores with alkaline hematin and towel weight, respectively. The percentage blood fraction was determined at various volumes of menstrual discharge. Alkaline hematin and fluid weight were highly correlated (r = .97). However, the percentage blood fraction progressively increased with total MFL and MBL score. After correction for this incremental rise in blood fraction, the menstrual pictogram gave a sensitivity of 82% and a specificity of 92% for a diagnosis of heavy menstrual bleeding. The menstrual pictogram (superabsorbent polymer-c version) provides a simple means of measuring MBL in the clinical setting. Copyright © 2014 American Society for Reproductive Medicine.

    Full Text Available BACKGROUND: Tuberculosis (TB is a contagious disease affected by multiple genetic and environmental factors. Several association studies have suggested that cellular immune response is vital for controlling and preventing of tuberculosis infection. Low molecular weight polypeptides (LMPs and transporters with antigen processing (TAPs are the main molecules in the processing and presentation pathway for intracellular antigens. This study was performed to elucidate whether these antigen-processing genes (LMP/TAP polymorphisms could be associated with the risk of tuberculosis infection in China. METHODOLOGY/PRINCIPAL FINDINGS: We recruited 205 active pulmonary tuberculosis patients and 217 normal controls from Li population for this study. Four polymorphisms of LMP/TAP genes were determined by PCR-RFLP assay and haplotypes were constructed by software PHASE 1.0. Of the total four polymorphisms, genotype frequencies of LMP7 AA homozygote and CA heterozygote were significantly greater among cases compared to controls, with odds ratio of 3.77 (95% CI: 1.60-8.89; P = 0.002 and 2.97 (95% CI: 1.80-4.90; P<0.0001, respectively. The genotypes of TAP1-2 GG homozygote and AG heterozygote were more frequent in subjects with TB than in controls, with odds ratio of 3.94 (95% CI: 1.82-8.53; P = 0.001 and 2.87 (95% CI: 1.75-4.71; P<0.0001, respectively. Similarly, we found that haplotype B which carried LMP7 and TAP1-2 variations significantly increased the susceptibility to TB (OR = 3.674, 95% CI: 2.254-5.988; P<0.0001. Moreover, it is noteworthy that the homozygote of wild haplotype A (A/A may be a strong protection for TB infection. CONCLUSIONS: Our findings suggested that LMP/TAP gene polymorphisms might be risk factors for TB infection among Li population in China.

    Highlights: •Mouse model of human Burkitt lymphoma revealed cancer inhibition by PL. •Treatment with PL led to apoptosis of malignant but not normal B cells. •PL inhibited LMP1–NF-κB–Myc-dependent target genes including p21-encoding Cdkn1a. •PL holds promise for new interventions approaches to hematologic malignancies. -- Abstract: Piperlongumine (PL), isolated from the fruit of Long pepper, Piper longum, is a cancer-inhibiting compound that selectively kills tumor cells while sparing their normal counterparts. Here we evaluated the efficacy with which PL suppresses malignant B cells derived from a newly developed, double-transgenic mouse model of human endemic Burkitt lymphoma (BL), designated mCD40-LMP1/iMyc{sup Eμ}. PL inhibited tumor cell proliferation in a concentration-dependent manner and induced apoptosis of neoplastic but not normal B cells. Treatment with PL resulted in downregulation of EBV-encoded LMP1, cellular Myc, constitutive NF-κB activity, and a host of LMP1-Myc-NF-κB-regulated target genes including Aurka, Bcat1, Bub1b, Ccnb1, Chek1, Fancd2, Tfrc and Xrcc6. Of note, p21{sup Cip1}-encoding Cdkn1a was suppressed independent of changes in Trp53 mRNA levels and p53 DNA-binding activity. Considering the central role of the LMP1–NF-κB–Myc axis in B-lineage neoplasia, these findings further our understanding of the mechanisms by which PL inhibits B-lymphoma and provide a preclinical rationale for the inclusion of PL in new interventions in blood cancers.

Treatment with PL resulted in downregulation of EBV-encoded LMP1, cellular Myc, constitutive NF-κB activity, and a host of LMP1-Myc-NF-κB-regulated target genes including Aurka, Bcat1, Bub1b, Ccnb1, Chek1, Fancd2, Tfrc and Xrcc6. Of note, p21 Cip1 -encoding Cdkn1a was suppressed independent of changes in Trp53 mRNA levels and p53 DNA-binding activity. Considering the central role of the LMP1–NF-κB–Myc axis in B-lineage neoplasia, these findings further our understanding of the mechanisms by which PL inhibits B-lymphoma and provide a preclinical rationale for the inclusion of PL in new interventions in blood cancers

    Full Text Available Uterine leiomyosarcoma (Ut-LMS develops more frequently in the myometrium of the uterine body than in the uterine cervix. Although the development of gynecological tumors is often correlated with the secretion of female hormones that of Ut-LMS does not, and its risk factor(s remain unknown. Importantly, a diagnostic biomarker that can distinguish malignant tumor Ut-LMS from benign tumor leiomyoma (LMA, has yet to be established. Therefore, the risk factor(s associated with Ut-LMS need to be examined in order to establish a diagnosis and clinical treatment method. Mice with a homozygous deficiency for the proteasome b-ring subunit, low-molecular mass polypeptide (LMP2/b1i spontaneously develop Ut-LMS, with a disease prevalence of ~40% by 14 months of age. In recent studies, we showed that LMP2/b1i expression was absent in human Ut-LMS, but present in other human uterine mesenchymal tumors including uterine LMA. Moreover, LMP2/b1i is also known to negatively regulate human Ut-LMS tumorigenesis. Additional experiments furthermore revealed the differential expression of cyclin E and calponin h1 in human uterine mesenchymal tumors. Therefore, LMP2/b1i is a potential diagnostic biomarker when combined with the candidate molecules, cyclin E and calponin h1 for human Ut-LMS, and may be a targeted molecule for a new therapeutic approach.---------------------------------------------Cite this article as: Hayashi T, Horiuchi A Aburatani H, Ishiko O, Yaegashi N, Kanai Y, Zharhary D, Tonegawa S, Konishi I.

    Full Text Available Hormonal action is one of the main factors for behavioral change observed in women, during the menstrual cycle, and especially in the premenstrual period, most women report a variation of mood and anxiety. The aim of this work was to verify the degrees of anxiety during the menstrual cycle, charting their variation and the possible influence of oral contraceptive use. For this purpose 32 women, divided in two groups according to the use (B or not use (A of oral contraceptive, with selfapplication of the STAI (State-Trait Anxiety Inventory at three different times: before, during and after menstruation. The data was tabulated and analyzed statistically, indicating a variation of anxiety level for different menstrual periods, but with no significance as to anxiety type (trait or state or to the ingestion of contraceptive. For Trait-Anxiety, the post-test (Boferroni T-Test of variation among periods indicated significant difference for post-menstrual and other periods, in the A group; and between the premenstrual and menstrual periods, in the B group. For State Anxiety, the data indicated significant differences between the premenstrual and menstrual periods, in the A group, and between the premenstrual and menstrual periods and the menstrual and post-menstrual in the B group. The results indicate that: 1 the menstrual cycle is a generator of variations of related anxiety; 2 the use of oral contraceptives does not alter this relation; and 3 the correlated diminution of the Trait Anxiety may indicate alteration in self-perception of women during the menstrual cycle. Keywords: anxiety; mestrual cycle; STAI.

    The high prevalence of menstrual disorders during the first years after menarche is well recognized. This is usually a cause of concern for parents and patients, and a common reason for visiting the pediatrician. The immaturity of the hypothalamic-pituitary-ovarian axis is the major cause of these disorders, but there are also some general organic or emotional conditions that may alter the menstrual cycle, which is a sensitive indicator of health. Physiology of the menstrual cycle, its alterations, etiology, assessment, diagnosis and treatment are reviewed in this article.

    2004-01-01

    The latent membrane protein 2A (LMP2A) of Epstein-Barr virus (EBV) is an important mediator of viral latency in infected B-lymphocytes. LMP2A inhibits B-cell receptor (BCR) signaling in vitro and allows for the survival of BCR-negative B cells in vivo. In this study, we compared gene transcription in BCR-activated B cells from non-transgenic and LMP2A Tg6 transgenic mice. We found that the transcriptional induction and down-regulation of many genes that normally occurs in B cells following BCR activation did not occur in B cells from LMP2A Tg6 transgenic mice. Furthermore, LMP2A induced the expression of various transcription factors and genes associated with DNA/RNA metabolism, which may allow for the altered transcriptional regulation observed in BCR-activated B cells from LMP2A Tg6 mice. These results suggest that LMP2A may inhibit the downstream effects of BCR signaling by directly or indirectly altering gene transcription to ensure EBV persistence in infected B cells

    Full Text Available Hormonal disorders in the menstrual cycle can affect labyrinthine fluid homeostasis, causing balance and hearing dysfunctions. STUDY DESIGN: Clinical prospective. AIM: compare the results from vestibular tests in young women, in the premenstrual and postmenstrual periods. MATERIALS AND METHODS: twenty women were selected with ages ranging from 18 to 35 years, who were not using any kind of contraceptive method for at least six months, and without vestibular or hearing complaints. The test was carried out in each subject before and after the menstrual period, respecting the limit of ten days before or after menstruation. RESULTS: there was a statistically significant difference in the menstrual cycle phases only in the following vestibular tests: calibration, saccadic movements, PRPD and caloric-induced nystagmus. We also noticed that age; a regular menstrual cycle; hearing loss or dizziness cases in the family; and premenstrual symptoms such as tinnitus, headache, sleep disorders, anxiety, nausea and hyperacusis can interfere in the vestibular test. CONCLUSION: there are differences in the vestibular tests of healthy women when comparing their pre and postmenstrual periods.As alterações hormonais do ciclo menstrual podem comprometer a homeostase dos fluidos labirínticos, gerando alterações no equilíbrio e na audição.

    2015-05-01

    Full Text Available The Epstein-Barr virus (EBV encoded oncoprotein Latent Membrane Protein 1 (LMP1 signals through two C-terminal tail domains to drive cell growth, survival and transformation. The LMP1 membrane-proximal TES1/CTAR1 domain recruits TRAFs to activate MAP kinase, non-canonical and canonical NF-kB pathways, and is critical for EBV-mediated B-cell transformation. TRAF1 is amongst the most highly TES1-induced target genes and is abundantly expressed in EBV-associated lymphoproliferative disorders. We found that TRAF1 expression enhanced LMP1 TES1 domain-mediated activation of the p38, JNK, ERK and canonical NF-kB pathways, but not non-canonical NF-kB pathway activity. To gain insights into how TRAF1 amplifies LMP1 TES1 MAP kinase and canonical NF-kB pathways, we performed proteomic analysis of TRAF1 complexes immuno-purified from cells uninduced or induced for LMP1 TES1 signaling. Unexpectedly, we found that LMP1 TES1 domain signaling induced an association between TRAF1 and the linear ubiquitin chain assembly complex (LUBAC, and stimulated linear (M1-linked polyubiquitin chain attachment to TRAF1 complexes. LMP1 or TRAF1 complexes isolated from EBV-transformed lymphoblastoid B cell lines (LCLs were highly modified by M1-linked polyubiqutin chains. The M1-ubiquitin binding proteins IKK-gamma/NEMO, A20 and ABIN1 each associate with TRAF1 in cells that express LMP1. TRAF2, but not the cIAP1 or cIAP2 ubiquitin ligases, plays a key role in LUBAC recruitment and M1-chain attachment to TRAF1 complexes, implicating the TRAF1:TRAF2 heterotrimer in LMP1 TES1-dependent LUBAC activation. Depletion of either TRAF1, or the LUBAC ubiquitin E3 ligase subunit HOIP, markedly impaired LCL growth. Likewise, LMP1 or TRAF1 complexes purified from LCLs were decorated by lysine 63 (K63-linked polyubiqutin chains. LMP1 TES1 signaling induced K63-polyubiquitin chain attachment to TRAF1 complexes, and TRAF2 was identified as K63-Ub chain target. Co-localization of M1- and K63

    Night work has been associated with adverse effects in terms of reproductive health. Specifically, menstruation has been suggested to be negatively impacted by night work, which again may influence fertility. This study investigated whether working nights is related to menstrual characteristics and if there is a relationship between shift work disorder (SWD) and menstruation. The study was cross-sectional, response rate 38%. The sample comprised female nurses who were members of the Norwegian Nurses Association; below 50 yr of age, who were not pregnant, did not use hormonal pills or intrauterine devices and who had not reached menopause (n=766). The nurses answered a postal survey including questions about night work and menstrual characteristics. Fifteen per cent reported to have irregular menstruations. Thirty-nine per cent of the nurses were classified as having SWD. Logistic regression analyses concerning the relationship between irregular menstruations and night work did not show any associations. Furthermore, no associations were found between cycle length or bleeding period and night work parameters. No associations were found between menstrual characteristics and SWD.

    The role of the Epstein-Barr virus (EBV), a ubiquitous lymphotropic human herpesvirus type 4, in the etiology of nasopharyngeal carcinoma (NPC) is not fully understood. The mechanism of NPC carcinogenesis, associated with the virus, is also not clear. The objective of present investigation was to carry out comparative analysis of the structure of an LMP1 oncogene of EBV in viral isolates obtained from patients with two types of tumors of the oral cavity: (a) associated (i.e., NPC) and (b) not associated (other tumors of the same anatomical region, OTOC) with EBV. Comparative analysis of C-terminal regions of LMP1 variants that was based on a sequence analysis of LMP1 from tumor, blood and throat washing samples of NPC and OTOC patients showed that all structural characteristics of LMP1 in both groups of patients were genetically similar, and differences found between compared parameters were statistically insignificant. Thus, for the first time it has been revealed that in NPC and OTOC patients in Russia genetically related EBV strains with structurally similar LMP1 variants are persisting that are likely to reflect a polymorphism of the virus circulating in population. The findings allow us to suggest that in non-NPC-endemic regions of the world, which include Russia, the risk of NPC development does not depend on the EBVstrain and its variant of LMP1 so much, but mostly from the genetic predisposition of infected persons to the disease and the exposure to other, as yet unknown agents.

    Graphical abstract: Display Omitted - Highlights: • Pollutant emissions estimated based on locational marginal price and eGRID data. • Stochastic model using IEEE RTS-96 system used to evaluate LMP approach. • Incorporating membership function enhanced reliability of pollutant estimate. • Error in pollutant estimate typically 2 and X and SO 2 . - Abstract: To evaluate the sustainability of systems that draw power from electrical grids there is a need to rapidly and accurately quantify pollutant emissions associated with power generation. Air emissions resulting from electricity generation vary widely among power plants based on the types of fuel consumed, the efficiency of the plant, and the type of pollution control systems in service. To address this need, methods for estimating real-time air emissions from power generation based on locational marginal prices (LMPs) have been developed. Based on LMPs the type of the marginal generating unit can be identified and pollutant emissions are estimated. While conceptually demonstrated, this LMP approach has not been rigorously tested. The purpose of this paper is to (1) improve the LMP method for predicting pollutant emissions and (2) evaluate the reliability of this technique through power system simulations. Previous LMP methods were expanded to include marginal emissions estimates using an LMP Emissions Estimation Method (LEEM). The accuracy of emission estimates was further improved by incorporating a probability distribution function that characterize generator fuel costs and a membership function (MF) capable of accounting for multiple marginal generation units. Emission estimates were compared to those predicted from power flow simulations. The improved LEEM was found to predict the marginal generation type approximately 70% of the time based on typical system conditions (e.g. loads and fuel costs) without the use of a MF. With the addition of a MF, the LEEM was found to provide emission estimates with

To compare the pain perception and anxiety levels of female patients undergoing scaling and root planing during menstrual (perimenstrual period with those observed during postmenstrual period. Materials and Methods. This was a single blind study, with a split-mouth design. Forty-four women with chronic periodontitis with regular menstrual cycles were subjected to complete Corah’s Dental Anxiety Scale (DAS during their first debridement visit. Patients were randomly selected to undergo their first debridement visit during either their menstrual or postmenstrual period. Scaling was performed under local anesthesia in bilateral quadrants of patients during the periods. Visual Analogue Scale (VAS was used to score pain levels for each quadrant after performing scaling and root planing. Results. Increase in pain perception among females during their menstrual or perimenstrual period was significantly greater than their postmenstrual period (P < 0.05. It is observed that women whose first appointment was given in perimenstrual period had more pain (VAS (P = 0.0000 when compared to those women whose first appointment was given in postmenstrual period. Conclusion. Females in their menstrual period demonstrated higher pain responses and high anxiety levels to supra- and subgingival debridement. This increase in the pain levels of women during their menstrual period was statistically significant. If the appointments are given in postmenstrual period, women feel less pain.

    ABSTRACT Latent membrane protein 1 (LMP1) is a major oncogene essential for primary B cell transformation by Epstein-Barr virus (EBV). Previous studies suggested that some transcription factors, such as PU.1, RBP-Jκ, NF-κB, and STAT, are involved in this expression, but the underlying mechanism is unclear. Here, we identified binding sites for PAX5, AP-2, and EBF in the proximal LMP1 promoter (ED-L1p). We first confirmed the significance of PU.1 and POU domain transcription factor binding for activation of the promoter in latency III. We then focused on the transcription factors AP-2 and early B cell factor (EBF). Interestingly, among the three AP-2-binding sites in the LMP1 promoter, two motifs were also bound by EBF. Overexpression, knockdown, and mutagenesis in the context of the viral genome indicated that AP-2 plays an important role in LMP1 expression in latency II in epithelial cells. In latency III B cells, on the other hand, the B cell-specific transcription factor EBF binds to the ED-L1p and activates LMP1 transcription from the promoter. IMPORTANCE Epstein-Barr virus (EBV) latent membrane protein 1 (LMP1) is crucial for B cell transformation and oncogenesis of other EBV-related malignancies, such as nasopharyngeal carcinoma and T/NK lymphoma. Its expression is largely dependent on the cell type or condition, and some transcription factors have been implicated in its regulation. However, these previous reports evaluated the significance of specific factors mostly by reporter assay. In this study, we prepared point-mutated EBV at the binding sites of such transcription factors and confirmed the importance of AP-2, EBF, PU.1, and POU domain factors. Our results will provide insight into the transcriptional regulation of the major oncogene LMP1. PMID:26819314

    2017-11-01

    Full Text Available Latent membrane protein 1 (LMP1 is a major oncogene encoded by Epstein–Barr virus (EBV and is essential for immortalization of B cells by the virus. Previous studies suggested that several transcription factors, such as PU.1, RBP-Jκ, NFκB, EBF1, AP-2 and STAT, are involved in LMP1 induction; however, the means by which the oncogene is negatively regulated remains unclear. Here, we introduced short mutations into the proximal LMP1 promoter that includes recognition sites for the E-box and Ikaros transcription factors in the context of EBV-bacterial artificial chromosome. Upon infection, the mutant exhibited increased LMP1 expression and EBV-mediated immortalization of B cells. However, single mutations of either the E-box or Ikaros sites had limited effects on LMP1 expression and transformation. Our results suggest that this region contains a suppressive cis-regulatory element, but other transcriptional repressors (apart from the E-box and Ikaros transcription factors may remain to be discovered.

    In the early 1970s the effort was begun to examine the clinical benefits of "menstrual induction" (MI) at 6 weeks pregnancy (last menstrual period), in the belief that if pregnancy is to be terminated there was no sound medical nor psychological reason to delay the procedure. It was found that the transcervical, intrauterine delivery of a "PG-impact" compromised the conceptus and terminated pregnancy in 95% of the cases, with clinical symptoms of menstruation rather than abortion. The side-effects were acceptable; the prematurity rate did not increase in subsequent pregnancies. Yet, the need for strict asepsis limited the use of this otherwise simple and effective procedure. Recently, this limitation has been overcome by the development of the PGE2 analogue 16-phenoxy-w17,18,19,20 tetranor-PGE2-methyl sulfanylamide ('Sulproston'). Clinical trials have been done in terms of dealing with the questions of efficacy, acceptability, and preference. 90 volunteers have been studied. At 14 days follow-up the success rate (negative pregnancy test) was 96%. The side effects were acceptable -- vomiting 26%, diarrhea 10%, and endometritis 2%. Of the 42 patients interviewed, 90% were satisfied with the procedure. Of those who had previously experienced surgical interruption, 89% preferred this pharmacological method.

  11. Roles of the kinase TAK1 in TRAF6-dependent signaling by CD40 and its oncogenic viral mimic, LMP1.

    Directory of Open Access Journals (Sweden)

    Kelly M Arcipowski

    Full Text Available The Epstein-Barr virus (EBV-encoded protein latent membrane protein 1 (LMP1 is essential for EBV-mediated B cell transformation and plays a critical role in the development of post-transplant B cell lymphomas. LMP1 also contributes to the exacerbation of autoimmune diseases such as systemic lupus erythematosus (SLE. LMP1 is a functional mimic of the tumor necrosis factor receptor (TNFR superfamily member CD40, and relies on TNFR-associated factor (TRAF adaptor proteins to mediate signaling. However, LMP1 activation signals to the B cell are amplified and sustained compared to CD40 signals. We previously demonstrated that LMP1 and CD40 use TRAF molecules differently. Although associating with CD40 and LMP1 via separate mechanisms, TRAF6 plays a significant role in signal transduction by both. It is unknown whether TRAF6 mediates CD40 versus LMP1 functions via distinct or shared pathways. In this study, we tested the hypothesis that TRAF6 uses the kinase TAK1 to trigger important signaling pathways following both CD40 and LMP1 stimulation. We determined that TAK1 was required for JNK activation and interleukin-6 (IL-6 production mediated by CD40 and LMP1, in both mouse and human B cells. Additionally, TRAF3 negatively regulated TRAF6-dependent, CD40-mediated TAK1 activation by limiting TRAF6 recruitment. This mode of regulation was not observed for LMP1 and may contribute to the dysregulation of LMP1 compared to CD40 signals.

    During the menstrual cycle, the influence of hormonal variations on dietary habits in women has been suggested by several studies. In this context, our work aimed to assess the spontaneous food intake and the anthropometric parameters of women at different periods of their menstrual cycles. This prospective study included 30 healthy women with regular periods (28 to 30 days), aged between 18 and 45. We assessed the spontaneous food intake and the anthropometric measurements (weight and waist circumference) of the participants, during the follicular, peri-ovulatory and luteal phases of their menstrual cycles. Our results showed a slight but significant increase in body weight during the luteal phase (P=0.022) and the follicular phase (P=0.017) compared with the peri-ovulatory phase, without any significant change in waist circumference. The caloric intake increased during the peri-ovulatory (P<0.001) and the luteal phases (P<0.001), compared with the follicular phase, with a significant increase in carbohydrate (P<0.001), lipid (P=0.008) and protein (P=0.008) intake. Our study showed a significant decrease in women's weight during the peri-ovulatory phase, with a significant increase in caloric intake during the luteal phase of the menstrual cycle. Divergent results have been reported by other authors and the physiopathology of these changes is still poorly understood. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    A novel strategy to enhance bone repair is to combine angiogenic factors and osteogenic factors. We combined vascular endothelial growth factor (VEGF) and LIM mineralization protein-1 (LMP-1) by using an internal ribosome entry site to link the genes within a single plasmid. We then evaluated the effects on osteoblastic differentiation in vitro and ectopic bone formation in vivo with a subcutaneously placed PLAGA scaffold loaded with a cloned mouse osteoprogenitor cell line, D1, transfected with plasmids containing VEGF and LMP-1 genes. The cells expressing both genes elevated mRNA expression of RunX2 and β-catenin and alkaline phosphatase activity compared to cells from other groups. In vivo, X-ray and micro-CT analysis of the retrieved implants revealed more ectopic bone formation at 2 and 3 weeks but not at 4 weeks compared to other groups. The results indicate that the combination of the therapeutic growth factors potentiates cell differentiation and may promote osteogenesis.

    We introduce orbital specific virtuals (OSVs) to represent the truncated pair-specific virtual space in periodic local Møller-Plesset perturbation theory of second order (LMP2). The OSVs are constructed by diagonalization of the LMP2 amplitude matrices which correspond to diagonal Wannier-function (WF) pairs. Only a subset of these OSVs is adopted for the subsequent OSV-LMP2 calculation, namely, those with largest contribution to the diagonal pair correlation energy and with the accumulated value of these contributions reaching a certain accuracy. The virtual space for a general (non diagonal) pair is spanned by the union of the two OSV sets related to the individual WFs of the pair. In the periodic LMP2 method, the diagonal LMP2 amplitude matrices needed for the construction of the OSVs are calculated in the basis of projected atomic orbitals (PAOs), employing very large PAO domains. It turns out that the OSVs are excellent to describe short range correlation, yet less appropriate for long range van der Waals correlation. In order to compensate for this bias towards short range correlation, we augment the virtual space spanned by the OSVs by the most diffuse PAOs of the corresponding minimal PAO domain. The Fock and overlap matrices in OSV basis are constructed in the reciprocal space. The 4-index electron repulsion integrals are calculated by local density fitting and, for distant pairs, via multipole approximation. New procedures for determining the fit-domains and the distant-pair lists, leading to higher efficiency in the 4-index integral evaluation, have been implemented. Generally, and in contrast to our previous PAO based periodic LMP2 method, the OSV-LMP2 method does not require anymore great care in the specification of the individual domains (to get a balanced description when calculating energy differences) and is in that sense a black box procedure.

    Menstruation is suggested to affect multiple sclerosis (MS) symptoms, while the effect of MS on menstruation is not studied before. Here, we aimed to compare the pattern of menstrual cycle and its symptoms between MS patients and healthy controls. This is a cross-sectional study conducted during 2015-2016 in MS clinic of Kashani hospital, Isfahan, Iran. We included female patients > 14 years with diagnosis of relapsing-remitting MS, and healthy subjects as the control group. We collected data regarding menarche age, menstrual characteristics, history of premenstrual syndrome, the amount of menstrual bleeding, and the possible perimenstrual symptoms from all subjects. Also, MS patients were asked to report changes in menstrual characteristics after MS occurrence. The final study population contained 181 MS patients and 202 healthy subjects. The mean age in MS and control group were 36.04 ± 9.86 and 35.16 ± 11.30, respectively (P-value = 0.426). Menarche age in MS patients and control group were not statistically different (13.59 ± 1.87 and 13.29 ± 1.53, respectively; P-value = 0.087). Changing menstrual characteristics was reported in 70 MS patients (38.7%). Irregular menstrual cycle increased from 21% to 40.3% after occurrence of MS (P-value < 0.001) and was reported 24.7% in the control group. MS patients versus controls reported more symptoms before, during, and after their menstrual period (P-values < 0.001). We found no difference regarding menstrual characteristics in MS patients before onset of the disease and healthy controls. Irregular menstrual cycle was observed more after the disease occurrence while other menstrual characteristics did not change. Moreover, MS patients reported many more perimenstrual symptoms.

    Previous data demonstrate that Epstein-Barr Virus Latent Membrane Protein 2A (LMP2A) enhances IL-10 to promote the survival of LMP2A-expressing B cell lymphomas. Since STAT3 is an important regulator of IL-10 production, we hypothesized that LMP2A activates a signal transduction cascade that increases STAT3 phosphorylation to enhance IL-10. Using LMP2A-negative and -positive B cell lines, the data indicate that LMP2A requires the early signaling molecules of the Syk/RAS/PI3K pathway to increase IL-10. Additional studies indicate that the PI3K-regulated kinase, BTK, is responsible for phosphorylating STAT3, which ultimately mediates the LMP2A-dependent increase in IL-10. These data are the first to show that LMP2A signaling results in STAT3 phosphorylation in B cells through a PI3K/BTK-dependent pathway. With the use of BTK and STAT3 inhibitors to treat B cell lymphomas in clinical trials, these findings highlight the possibility of using new pharmaceutical approaches to treat EBV-associated lymphomas that express LMP2A.

    The relationships between the expression of ID2, EBV-LMP1 and P16(INK4A) in Chinese classical Hodgkin lymphoma are unknown and need exploring. Samples of classical Hodgkin lymphoma from 60 Chinese patients were analyzed for the expression of ID2, EBV-LMP1 and p16(INK4A) proteins by immunohistochemistry. ID2 protein was expressed in 83.3% of this group of classical Hodgkin lymphoma, staining strongly in both cytoplasm and nucleus of the Hodgkin and Reed-Sternberg (HRS) cells. EBV-LMP1 and P16(INK4A) were overexpressed in 85.0% and 71.7% of Hodgkin lymphoma, respectively. EBV-LMP1 was noted in the cytoplasm, membrane and nucleus of HRS cells; P16(INK4A) was in the nucleus and cytoplasm. Microscopically, ID2, EBV-LMP1 and P16(INK4A) staining distinguished the HRS cells from the complex background of lymphocytes. ID2 was positively correlated with EBV-LMP1(P < 0.01), but P16(INK4A) was inversely related to EBV-LMP1 (P < 0.05). It is suggested that ID2, EBV-LMP1 and P16(INK4A) could play an important role in the evolution of classical Hodgkin lymphoma, and be considered as potential adjunct markers to identify HRS cells in diagnosis

    Electricity market design in the United States is increasingly dominated by locational marginal pricing (LMP) of energy and transmission. LMP markets are typically coupled with periodic auctions of financial transmission rights (FTRs) to hedge transmission price risks. While LMP designs offer considerable advantages, forward price discovery in these markets requires participants to form efficient expectations on spot congestion price differences. In this paper, we examine trends in the efficiency of one of the early LMP markets, the New York Independent System Operator (NYISO), analyzing a panel data set of over 9000 contracts over a six-year period beginning September 2000. We show that NYISO FTR markets were inefficient in their early years, but that market participants learned to predict forward prices and thus efficiency improved for FTRs not solely within the New York City/Long Island sub-region. FTRs within this sub-region, which has a number of special characteristics, remain relatively inefficient. (author)

  20. Genetic diversity of EBV-encoded LMP1 in the Swiss HIV Cohort Study and implication for NF-Κb activation.

    Directory of Open Access Journals (Sweden)

    Emilie Zuercher

    Full Text Available Epstein-Barr virus (EBV is associated with several types of cancers including Hodgkin's lymphoma (HL and nasopharyngeal carcinoma (NPC. EBV-encoded latent membrane protein 1 (LMP1, a multifunctional oncoprotein, is a powerful activator of the transcription factor NF-κB, a property that is essential for EBV-transformed lymphoblastoid cell survival. Previous studies reported LMP1 sequence variations and induction of higher NF-κB activation levels compared to the prototype B95-8 LMP1 by some variants. Here we used biopsies of EBV-associated cancers and blood of individuals included in the Swiss HIV Cohort Study (SHCS to analyze LMP1 genetic diversity and impact of sequence variations on LMP1-mediated NF-κB activation potential. We found that a number of variants mediate higher NF-κB activation levels when compared to B95-8 LMP1 and mapped three single polymorphisms responsible for this phenotype: F106Y, I124V and F144I. F106Y was present in all LMP1 isolated in this study and its effect was variant dependent, suggesting that it was modulated by other polymorphisms. The two polymorphisms I124V and F144I were present in distinct phylogenetic groups and were linked with other specific polymorphisms nearby, I152L and D150A/L151I, respectively. The two sets of polymorphisms, I124V/I152L and F144I/D150A/L151I, which were markers of increased NF-κB activation in vitro, were not associated with EBV-associated HL in the SHCS. Taken together these results highlighted the importance of single polymorphisms for the modulation of LMP1 signaling activity and demonstrated that several groups of LMP1 variants, through distinct mutational paths, mediated enhanced NF-κB activation levels compared to B95-8 LMP1.

    A prospective study of the menstrual pattern and weight changes was made in the first year of training of 29 new female entrants to a professional ballet school. Seventy-nine per cent of the student girls had menstrual disturbances at entry: primary amenorrhoea, four; secondary amenorrhoea, 11; irregular menses, eight. The incidence of secondary amenorrhoea increase substantially by the end of the year (20), but was not associated with any significant change in body weight. Only three students menstruated regularly during the year. Menstrual regularity improved during periods of injury and long vacation and it appears that deterioration of the menstrual pattern during dancing periods was related to strenuous physical exercise rather than to any change in body weight.

    Nasal NK/T-cell lymphoma (NNKTL) is an Epstein-Barr virus (EBV)-associated malignancy and has distinct clinical and histological features. However, its genetic features are hitherto unclear. MicroRNAs (miRNAs) play a crucial role in the pathogenesis of several malignancies via regulating gene expression. In this study, we investigated whether the specific microRNAs were related to the tumor behaviors in NNKTL. MiRNA array and Quantitative RT-PCR analyses revealed that miR-15a was expressed at a much lower level in NNKTL cells (SNK-1, SNK-6, and SNT-8) than in normal peripheral NK cells and EBV-negative NK cell line KHYG-1. Quantitative PCR and western blot analyses showed that the expression of MYB and cyclin D1, which are validated targets of miR-15a, was higher in NNKTL cells. Transfection of NNKTL cells (SNK-6 and SNT-8) with a miR-15a precursor decreased MYB and cyclin D1 levels, thereby blocking G1/S transition and cell proliferation. Knockdown of EBV-encoded latent membrane protein 1 (LMP1) significantly increased miR-15a expression in SNK-6 cells. In NNKTL tissues, we found that reduced miR-15a expression, which correlated with MYB and cyclin D1 expression, was associated with poor prognosis of NNKTL patients. These data suggest that downregulation of miR-15a, possibly due to LMP1, implicates in the pathogenesis of NNKTL by inducing cell proliferation via MYB and cyclin D1. Thus, miR-15a could be a potential target for antitumor therapy and a prognostic predictor for NNKTL. Copyright © 2013 Wiley Periodicals, Inc.

    Ubiquitin C-terminal Hydrolase L1 (UCH-L1) has oncogenic properties and is highly expressed during malignancies. We recently documented that Epstein-Barr virus (EBV) infection induces uch-l1 expression. Here we show that Kaposi's Sarcoma-associated herpesvirus (KSHV) infection induced UCH-L1 expression, via cooperation of KSHV Latency-Associated Nuclear Antigen (LANA) and RBP-Jκ and activation of the uch-l1 promoter. UCH-L1 expression was also increased in Primary Effusion Lymphoma (PEL) cells co-infected with KSHV and EBV compared with PEL cells infected only with KSHV, suggesting EBV augments the effect of LANA on uch-l1. EBV latent membrane protein 1 (LMP1) is one of the few EBV products expressed in PEL cells. Results showed that LMP1 was sufficient to induce uch-l1 expression, and co-expression of LMP1 and LANA had an additive effect on uch-l1 expression. These results indicate that viral latency products of both human γ-herpesviruses contribute to uch-l1 expression, which may contribute to the progression of lymphoid malignancies. - Highlights: • Infection of endothelial cells with KSHV induced UCH-L1 expression. • KSHV LANA is sufficient for the induction of uch-l1. • Co-infection with KSHV and EBV (observed in some PELs) results in the additive induction of uch-l1. • EBV LMP1 also induced UCH-L1 expression. • LANA- and LMP1-mediated activation of the uch-l1 promoter is in part through RBP-Jκ.

    In low-income settings, many women and girls face activity restrictions during menses, owing to lack of affordable menstrual products. The menstrual cup (MC) is a nonabsorbent reusable cup that collects menstrual blood. We assessed the acceptability and performance of the MPower® MC compared to pads or tampons among women in a low-resource setting. We conducted a randomized two-period crossover trial at one site in Durban, South Africa, between January and November 2013. Participants aged 18-45 years with regular menstrual cycles were eligible for inclusion if they had no intention of becoming pregnant, were using an effective contraceptive method, had water from the municipal system as their primary water source, and had no sexually transmitted infections. We used a computer-generated randomization sequence to assign participants to one of two sequences of menstrual product use, with allocation concealed only from the study investigators. Participants used each method over three menstrual cycles (total 6 months) and were interviewed at baseline and monthly follow-up visits. The product acceptability outcome compared product satisfaction question scores using an ordinal logistic regression model with individual random effects. This study is registered on the South African Clinical Trials database: number DOH-27-01134273. Of 124 women assessed, 110 were eligible and randomly assigned to selected menstrual products. One hundred and five women completed all follow-up visits. By comparison to pads/tampons (usual product used), the MC was rated significantly better for comfort, quality, menstrual blood collection, appearance, and preference. Both of these comparative outcome measures, along with likelihood of continued use, recommending the product, and future purchase, increased for the MC over time. MC acceptance in a population of novice users, many with limited experience with tampons, indicates that there is a pool of potential users in low-resource settings.

    Full Text Available Background: Sexual function in women may be affected by their menstrual cycle. Lack of sexual drive is a deficiency or absence of sexual fantasies and desire for sexual activity. This study aims at determining the changes in sexual desire during the menstrual cycle and those associated with premenstrual syndrome (PMS and evaluates sexual desire during the menstrual cycle and the associated changes with PMS. Methods: The sample for this cross-sectional study includes 150 women employed in factories in Tehran. The instruments for data collection were questionnaires and journals of premenstrual experiences.Results: Analysis of the data showed that the mean age of the subjects was 31 years standard deviation = 8.46(. The most frequent decrease in sexual desire was during the week prior to the start of menstrual bleeding (27.3% and the least frequent was from the end of bleeding to one week before the next period of menstrual bleeding (5.3%. In 24.7% of the cases, an increase in sexual desire occurred during the middle of the menstrual cycle and 27.3% during the course of menstrual bleeding. Moreover, 10.7% of the subjects had an increase in sexual desire during the week before bleeding. Furthermore, a positive correlation was found between changes in sexual desire and PMS (p<0.001. In addition, a positive correlation was found between changes in sexual desire and breast tenderness, joint and muscle pain. Conclusions: The sexual desire of women, with or without PMS, changes during the menstrual cycle. The greatest decrease in sexual desire occurs during the first week before menstrual bleeding in women with PMS. Such information can greatly help toward understanding and treatment in sexual therapy for couples.

    Full Text Available BACKGROUND The major Problems occurring during the adolescent period is related to menstrual cycle. Data regarding the burden of menstrual disturbances in school going children of South India is lacking. Assessing the burden in such children may aid in revealing the current state of menstrual health and hence aiding the policy makes to take appropriate measures. Hence, we assessed the prevalence of menstrual disturbances in school going adolescent girls of South India. The primary aim of this study is to assess the burden of menstrual disorders in school going adolescent girls. The secondary objective were to assess individual menstrual disturbance in the study group and to assess the various factors influencing the menstrual health. MATERIALS AND METHODS This cross-sectional study was conducted in two government girl’s higher secondary school in the state of Tamil Nadu, India. After receiving approval, a structured questionnaire in the regional language (Tamil was distributed to the school going children between the age of 10 and 19 years. Demographic data and details regarding menstrual health were collected. Frequency of medical assistance and school absenteeism were also analysed in patients with dysmenorrhea. Data were analysed using the SPSS 13.0.1. RESULTS Data of 340 girls who have attained menarche and who have completed the questionnaire was analysed. The median age of menarche in the study group was 13 years. (IQR; 12, 14 and 13.2% attained early menarche(before12 years. There was a higher prevalence of menstrual disturbances; (46.2% with polymenorrhea and (12% with oligomenorrhea. there was a significantly higher usage of sanitary pads in our study population in our study group (98%. In addition, (41.5% had premenstrual symptoms and (36.8% had dysmenorrhea. With a higher prevalence of dysmenorrhea (n=125, 35 had school absenteeism.

    To estimate the effect of increased menstrual flow on the loss of work. Heavy or otherwise abnormal menstrual bleeding is a common problem among women in the reproductive age range. Until now, there has been no evidence of its effect on absences from work. We used data from the National Health Interview Survey 1999, a personal interview household survey using a nationwide representative sample of the civilian noninstitutionalized population of the United States. Participants were 3133 women aged between 18 and 64 years who reported having a natural menstrual period in the last 12 months and in the last 3 months, never having taken medication containing estrogen (except past use of oral contraceptives), and never having been told that they had reproductive cancer. Analysis was performed using data from 2805 women, 373 having self-described heavy flow and 2432 having normal flow. The main outcome measure was work loss associated with the degree of menstrual flow. Using binary logistic regression, age, marital status, education, family size, perception of health, and flow of menstrual periods are associated with work losses (P women who have a heavier flow are 72% as likely to be working as are women who have a lighter or normal flow. Menstrual bleeding has significant economic implications for women in the workplace: work loss from increased blood flow is estimated to be $1692 annually per woman.

    Abstract Objective Adolescent obesity has dramatically increased in recent decades, and along with that so have other medical comorbidities, such as hypertension, diabetes, hyperlipidemia, nonalcoholic steatohepatitis, polycystic ovary syndrome (PCOS), and pseudotumor cerebri. Obesity and related comorbidites may be contraindications to hormonal contraception, making contraception counseling of morbidly obese adolescents more challenging. Obese adolescent females seeking bariatric surgery need effective contraception in the postoperative period. This study is designed to determine the acceptance rate of the levonorgestrel-releasing intrauterine device (IUD) and describe common menstrual problems in obese adolescent bariatric surgery patients. Methods This is a historic cohort study of adolescent females who underwent bariatric surgery over a 2-year period at a tertiary referral center for pediatric obesity. Data were systematically abstracted. The percent of patients with menstrual problems and the acceptance rate for the levonorgestrel-releasing IUD were determined. Results Twenty-five adolescents met inclusion criteria. The mean age was 17.4 years (standard deviation [SD] 2.6), and the mean body mass index (BMI) was 51.4 (SD 6.3) kg/m2. Eighty-four percent were white. Twenty-eight percent had menorrhagia, 32% had oligomenorrhea, 40% had dysmenorrhea, and 36% had PCOS. Ninety-two percent (23 of 25) underwent IUD placement. Conclusions There was a high prevalence of menstrual problems among this sample of severely obese adolescent females. The majority accepted the IUD, indicating it is a viable option among this population. PMID:21413894

    Highlights: • Triptolide inhibits proliferation of EBV-positive lymphoma cells in vitro and in vivo. • Triptolide reduces expression of LMP1 by decreasing its transcription level. • Triptolide inhibits ED-L1 promoter activity. - Abstract: Epstein–Barr virus (EBV) infects various types of cells and mainly establishes latent infection in B lymphocytes. The viral latent membrane protein 1 (LMP1) plays important roles in transformation and proliferation of B lymphocytes infected with EBV. Triptolide is a compound of Tripterygium extracts, showing anti-inflammatory, immunosuppressive, and anti-cancer activities. In this study, it is determined whether triptolide inhibits proliferation of Epstein–Barr virus-positive B lymphocytes. The CCK-8 assays were performed to examine cell viabilities of EBV-positive B95-8 and P3HR-1 cells treated by triptolide. The mRNA and protein levels of LMP1 were examined by real time-PCR and Western blotting, respectively. The activities of two LMP1 promoters (ED-L1 and TR-L1) were determined by Dual luciferase reportor assay. The results showed that triptolide inhibited the cell viability of EBV-positive B lymphocytes, and the over-expression of LMP1 attenuated this inhibitory effect. Triptolide decreased the LMP1 expression and transcriptional levels in EBV-positive B cells. The activity of LMP1 promoter ED-L1 in type III latent infection was strongly suppressed by triptolide treatment. In addition, triptolide strongly reduced growth of B95-8 induced B lymphoma in BALB/c nude mice. These results suggest that triptolide decreases proliferation of EBV-induced B lymphocytes possibly by a mechanism related to down-regulation of the LMP1 expression

    Georg Hagemann

    Full Text Available BACKGROUND: There is increasing evidence for hormone-dependent modification of function and behavior during the menstrual cycle, but little is known about associated short-term structural alterations of the brain. Preliminary studies suggest that a hormone-dependent decline in brain volume occurs in postmenopausal, or women receiving antiestrogens, long term. Advances in serial MR-volumetry have allowed for the accurate detection of small volume changes of the brain. Recently, activity-induced short-term structural plasticity of the brain was demonstrated, challenging the view that the brain is as rigid as formerly believed. METHODOLOGY/PRINCIPAL FINDINGS: We used MR-volumetry to investigate short-term brain volume changes across the menstrual cycle in women or a parallel 4 week period in men, respectively. We found a significant grey matter volume peak and CSF loss at the time of ovulation in females. This volume peak did not correlate with estradiol or progesterone hormone levels. Men did not show any significant brain volume alterations. CONCLUSIONS/SIGNIFICANCE: These data give evidence of short-term hormone-dependent structural brain changes during the menstrual cycle, which need to be correlated with functional states and have to be considered in structure-associated functional brain research.

    To determine the frequency of menstrual problems after tubal ligation. Study Design: Descriptive study. Place and Duration of Study: This study was carried out in gynae department of PAF Hospital Sargodha, Pakistan from September 2011 to September 2012. Patients and methods: Two hundred patients were included in the study with menstrual problems after tubal ligation. Results: Forty seven percent of patients presented with menorrhagia, 28% presented with metrorrhagia, 13% patients were having complaints of polymenorrhoea and 5% patients presented with dysmenorrhea and 7% had oligomenorrhoea after tubal ligation. Thirty one percent of patients ended up in hysterectomy and 37% of patients had improvement of symptoms with medical treatment. Conclusion: Menstrual problem is a common complaint in our gyn ecological patients. A large number of these patients had history of tubal ligation. Menorrhagia, metrorrhagia, polymenorrhoea and dysmenorrhoea can occur after tubal ligation. Patients giving the history of menstrual problems and wants tubal ligation should be counselled earlier for these symptoms. (author)

    The reported incidence of exercise induced menstrual dysfunction varies among adolescent athletes from 12% to 66%. Women who experience amenorrhea associated with exercise are at risk for irretrievable bone mineral density loss and increased rate of stress fractures. Nurses should provide information to parents, coaches, and athletes about changes in exercise intensity and frequency, dietary modifications, and estrogen and progesterone replacement therapy to minimize the sequelae of exercise induced menstrual dysfunction.

    The onset of menses for adolescents with physical or intellectual disabilities can affect their independence and add additional concerns for families at home, in schools, and in other settings. The pediatrician is the primary health care provider to explore and assist with the pubertal transition and menstrual management. Menstrual management of both normal and abnormal cycles may be requested to minimize hygiene issues, premenstrual symptoms, dysmenorrhea, heavy or irregular bleeding, contraception, and conditions exacerbated by the menstrual cycle. Several options are available for menstrual management, depending on the outcome that is desired, ranging from cycle regulation to complete amenorrhea. The use of medications or the request for surgeries to help with the menstrual cycles in teenagers with disabilities has medical, social, legal, and ethical implications. This clinical report is designed to help guide pediatricians in assisting adolescent females with intellectual and/or physical disabilities and their families in making decisions related to successfully navigating menarche and subsequent menstrual cycles.

    Conditions of low energy availability (EA) (exercise energy expenditure (EEE) in a controlled laboratory setting. The purpose of this study was to examine if EA, defined as EA = (EI-EEE)/kgLBM, is associated with disruptions in ovarian function in exercising women. Menstrual status was confirmed with daily measures of urinary reproductive metabolites across 1-3 menstrual cycles or 28-day monitoring periods. EA was calculated for exercise days using EI from 3-day diet logs, EEE from heart-rate monitors and/or exercise logs for a 7-day period, and body composition from DXA. Resting energy expenditure (REE) was measured by indirect calorimetry. Total triiodothyronine (TT3) was measured from a fasting blood sample. 91 exercising women (23.1 ± 0.5 years) were categorized clinically as either exercising amenorrheic (ExAmen, n = 30), exercising oligomenorrheic (ExOligo, n = 20) or exercising eumenorrheic (ExEumen, n = 41). The eumenorrheic group was further divided into more specific subclinical groups as either exercising ovulatory (ExOv, n = 20), exercising inconsistent (ExIncon, n = 13), or exercising anovulatory (ExAnov, n = 8). An EA threshold of 30 kcal/kgLBM did not distinguish subclinical menstrual status (χ (2) = 0.557, p = 0.46) nor did EA differ across subclinical disturbance groups (p > 0.05). EA was lower in the ExAmen vs. ExEumen (30.9 ± 2.4 vs. 36.9 ± 1.7 kcal/kgLBM, p = 0.04). The ratio of REE/predicted REE was lower in the ExAmen vs. ExEumen (0.85 ± 0.02 vs. 0.92 ± 0.01, p = 0.001) as was TT3 (79.6 ± 4.1 vs. 95.3 ± 2.9 ng/mL, p = 0.002). EA did not differ among subclinical forms of menstrual disturbances in a large sample of exercising women, but EA did discriminate clinical menstrual status, i.e., amenorrhea from eumenorrhea.

    The tetraspanin protein CD63 has been recently described as a key factor in extracellular vesicle (EV) production and endosomal cargo sorting. In the context of Epstein-Barr virus (EBV) infection, CD63 is required for the efficient packaging of the major viral oncoprotein latent membrane protein 1 (LMP1) into exosomes and other EV populations and acts as a negative regulator of LMP1 intracellular signaling. Accumulating evidence has also pointed to intersections of the endosomal and autophagy pathways in maintaining cellular secretory processes and as sites for viral assembly and replication. Indeed, LMP1 can activate the mammalian target of rapamycin (mTOR) pathway to suppress host cell autophagy and facilitate cell growth and proliferation. Despite the growing recognition of cross talk between endosomes and autophagosomes and its relevance to viral infection, little is understood about the molecular mechanisms governing endosomal and autophagy convergence. Here, we demonstrate that CD63-dependent vesicle protein secretion directly opposes intracellular signaling activation downstream of LMP1, including mTOR-associated proteins. Conversely, disruption of normal autolysosomal processes increases LMP1 secretion and dampens signal transduction by the viral protein. Increases in mTOR activation following CD63 knockout are coincident with the development of serum-dependent autophagic vacuoles that are acidified in the presence of high LMP1 levels. Altogether, these findings suggest a key role of CD63 in regulating the interactions between endosomal and autophagy processes and limiting cellular signaling activity in both noninfected and virally infected cells. IMPORTANCE The close connection between extracellular vesicles and viruses is becoming rapidly and more widely appreciated. EBV, a human gamma herpesvirus that contributes to the progression of a multitude of lymphomas and carcinomas in immunocompromised or genetically susceptible populations, packages its major

    Full Text Available Today in the 21st century, we may boast of gender equality and women empowerment but the truth is somewhat implausible. Today women may have excelled in many spheres of life but, somewhere, she is still struggling to get out of her veil. In the name of tradition a women is always told to follow the rules what the society has set for her. A look at major religions of the world shows that, without exception, they have placed restrictions on menstruating women. Judaism, Christianity, Islam, Hinduism and Buddhism have all made statements about menstruation and its negative effect, leading to prohibitions about attending places of worship, cooking, physical intimacy and sometimes requiring women to live separately at this time. Present paper is a compilation of the information available on the menstrual taboo and various practices regarding it. For this extensive search was done on internet along with personal observations. The present study is carried out in order to provoke the need for increased research on the psychosocial aspects of menstruation by exploring the attitudes of society toward this monthly event.

    OBJECTIVE: The lifetime prevalence of major depression is twice as high in females as in males. Depression is known to increase at periods where there are changes in gonadal hormones. We examined pro- and anti-inflammatory cytokine levels during the normal menstrual cycle of healthy females compared to similar time points in healthy males. METHODS: Plasma concentrations of interleukin (IL)-4, IL-6, IL-8, IL-10, tumour necrosis factor-alpha (TNF-alpha) and soluble IL-6 receptor (sIL-6R) were measured with enzyme-linked immunosorbent assays in healthy females during the normal ovulatory menstrual cycle and also in males at similar time points. RESULTS: The luteal phase of the menstrual cycle is associated with increased production of sIL-6R, IL-4 and TNF-alpha compared to the early follicular phase. No change was observed in IL-6, IL-8 and IL-10 concentration throughout the menstrual cycle. We found IL-4 positively correlated with oestrogen while TNF-alpha positively correlated with progesterone. Females were found to have significantly higher concentrations of TNF-alpha and sIL-6R across all phases of the menstrual cycle, compared to males across similar time points. CONCLUSION: The normal menstrual cycle is associated with increased production of sIL-6R, IL-4 and TNF-alpha in the luteal phase compared to the early follicular phase. Females have significantly higher concentrations of sIL-6R and TNF-alpha at all time points across the menstrual cycle than males.

    Nutrition pattern is one of the important factors predicting menstrual distress, which varies among different cultures and countries. The purpose of this study is to determine the relationship between food frequency and menstrual distress in high school girls from Mashhad. This cross-sectional study was conducted in 2012 using a two-stage sampling method on 407 high school female students from Mashhad who met the inclusion criteria. Subjects completed questionnaires of demographic characteristics, food frequency, and Menstrual Distress Questionnaire (MDQ) during three phases of the menstrual cycle (a week before bleeding, during menstrual bleeding period, and a week after menstruation). The collected data were analyzed by statistical tests such as Pearson correlation coefficient test, independent Student's t-test, and one-way analysis of variance (ANOVA). Results showed that 87.7% of the students were at moderate economic status, 82.2% were exposed to cigarette smoke, 94.8% had mothers without university education, and 9.4% had working mothers. About 71% of the students reported minor pre-menstruation distress, 81% reported minor distress during bleeding, and 39% reported minor post-menstruation distress. In addition, the mean (SD) values for sweet-fatty foods, salty-fatty foods, fast foods, and caffeine were 3.6, 3.3, 1.3, and 10.2 per week, respectively. In addition, Pearson correlation coefficient test showed no significant correlation between total menstruation distress and food frequency (P > 0.05). With regard to the inappropriate food frequency and high intensity of menstrual distress among high school students and as health care and educational efforts for prevention and health promotion in society are among the duties of health workers, the results of this study can help the officials involved in education to emphasize on nutrition and the menstrual health of students.

    Full Text Available Nasopharyngeal carcinoma (NPC is a multifactorial disease that is endemic geographically in the world. Indonesian population has a highly incidence rate that is 6.2/100,000 people year. The pathogenesis of NPC is more directly reflected by carcinoma-specific viral transcriptional activity at the site of primary tumour. Epstein-Barr virus (EBV infection in NPC is reflected by the expression of EBV latent and lytic gene. In fact, mRNA Latent Membrane Protein 1 (LMP1 EBV expression was an important latent infection biomarker. The aim of this study was to determine a potential use of relative expression of mRNA LMP1 EBV from formalin-fixed paraffin embedded (FFPE tumour biopsy in NPC as a tumour biomarker. This reseach design was a cross sectional study. The samples were the archived specimens of FFPE tumour biopsy from NPC WHO-3 patient which were collected from untreated patients from 2014 in the Department of Pathology Anatomy, Prof. dr. Margono Soekarjo Hospital, Purwokerto. The expression of mRNA LMP1 EBV expression was determined by RT-PCR technique. The positivity of mRNA LMP1 EBV expression was 51.9%, indicating a moderate positivity. The result proved that the expression of mRNA LMP1 EBV from FFPE NPC WHO-3 tumour biopsy was a potential biomarker of NPC diagnosis. The molecular methods would improved the management of NPC, particularly in the histopathological diagnosis of NPC.

    To compare the effects of a hypocaloric low-fat diet with those of a very low carbohydrate diet on body mass index (BMI), waist circumference (WC), and menstrual function in overweight adolescent females with polycystic ovary syndrome (PCOS). Randomized pilot trial of two diets in a prospective, 12-week study. A hospital-based, academic adolescent medicine division. 24 females, age 12-22 years (mean 15.8 ± 2.2), with PCOS and a BMI above the 85(th) percentile for age (mean 35.7 ± 6.0 kg/m(2)). Nutrition counseling was given biweekly, and dietary compliance, menstrual history, and weight were recorded. WC was measured at the beginning and end of the study. Changes in weight, BMI, WC, and improvement in menstrual function over the course of the study period. 16 participants completed the study. 12 completers menstruated during the study period, 8 with regularity. The number of periods over 3 months increased from 0.6 ± 0.6 pre-treatment to 1.6 ± 1.3 post-treatment (P = 0.003). Overall, weight loss averaged 6.5% (P weight were 3.4 times more likely to have improved menstrual function (P = 0.001). There were no statistically significant differences between the two groups. Weight loss is feasible in adolescents with PCOS and results in significant improvements in BMI, WC, and menstrual function. Weight management may be preferable as first-line treatment in adolescents, because it targets both the menstrual dysfunction and risk factors for long-term morbidity associated with PCOS.

    To characterize menstrual bleeding patterns and treatment of heavy menstrual bleeding in adolescents with bleeding disorders. We conducted a retrospective review of female patients aged nine to 21 years with known bleeding disorders who attended a pediatric gynecology, hematology, and comprehensive hematology/gynecology clinic at a children's hospital in a metropolitan area. Prevalence of heavy menstrual bleeding at menarche, prolonged menses, and irregular menses among girls with bleeding disorders and patterns of initial and subsequent treatment for heavy menstrual bleeding in girls with bleeding disorders. Of 115 participants aged nine to 21 years with known bleeding disorders, 102 were included in the final analysis. Of the 69 postmenarcheal girls, almost half (32/69, 46.4%) noted heavy menstrual bleeding at menarche. Girls with von Willebrand disease were more likely to have menses lasting longer than seven days. Only 28% of girls had discussed a treatment plan for heavy menstrual bleeding before menarche. Hormonal therapy was most commonly used as initial treatment of heavy menstrual bleeding. Half (53%) of the girls failed initial treatment. Combination (hormonal and non-hormonal therapy) was more frequently used for subsequent treatment. Adolescents with bleeding disorders are at risk of heavy bleeding at and after menarche. Consultation with a pediatric gynecologist and/or hematologist prior to menarche may be helpful to outline abnormal patterns of menstrual bleeding and to discuss options of treatment in the event of heavy menstrual bleeding.

    Heavy menstrual bleeding (HMB) is an important physical and social problem for women. Oral treatment for HMB includes antifibrinolytic drugs, which are designed to reduce bleeding by inhibiting clot-dissolving enzymes in the endometrium.Historically, there has been some concern that using the antifibrinolytic tranexamic acid (TXA) for HMB may increase the risk of venous thromboembolic disease. This is an umbrella term for deep venous thrombosis (blood clots in the blood vessels in the legs) and pulmonary emboli (blood clots in the blood vessels in the lungs). To determine the effectiveness and safety of antifibrinolytic medications as a treatment for heavy menstrual bleeding. We searched the Cochrane Gynaecology and Fertility (CGF) Group trials register, CENTRAL, MEDLINE, Embase, PsycINFO and two trials registers in November 2017, together with reference checking and contact with study authors and experts in the field. We included randomized controlled trials (RCTs) comparing antifibrinolytic agents versus placebo, no treatment or other medical treatment in women of reproductive age with HMB. Twelve studies utilised TXA and one utilised a prodrug of TXA (Kabi). We used standard methodological procedures expected by Cochrane. The primary review outcomes were menstrual blood loss (MBL), improvement in HMB, and thromboembolic events. We included 13 RCTs (1312 participants analysed). The evidence was very low to moderate quality: the main limitations were risk of bias (associated with lack of blinding, and poor reporting of study methods), imprecision and inconsistency.Antifibrinolytics (TXA or Kabi) versus no treatment or placeboWhen compared with a placebo, antifibrinolytics were associated with reduced mean blood loss (MD -53.20 mL per cycle, 95% CI -62.70 to -43.70; I² = 8%; 4 RCTs, participants = 565; moderate-quality evidence) and higher rates of improvement (RR 3.34, 95% CI 1.84 to 6.09; 3 RCTS, participants = 271; moderate-quality evidence). This suggests that

    1979-07-01

    In a randomized crossover study 15 dysmenorrheic women were treated during two consecutive menstrual period, once with the potent prostaglandin-synthesis inhibitor: ibuprofen and once with an identical looking placebo. Each patient was medicated for 12 hours during the first day of her menstrual flow and was subsequently fitted with a cervical cup for the collection of menstrual blood during three hours. In these samples the concentrations of prostaglandin (PG)F and PGE were measured by radioimmunoassay. The patients receiving placebo had high PGF levels 135 +/- 27 ng/ml (Mean +/- S.E.) which were significnatly reduced by Ibuprofen to 24 +/- 5 ng/ml (P less than 0.001). The PGE concentrations decreased from 5 +/- 1 ng/ml to 2 +/- 1 ng/ml (P less than 0.05). Ibuprofen also reduced the menstrual pain significantly (P less than 0.001). These results substantiate the earlier conclusion that a causal relationship exists between effective treatment with PG-synthesis inhibitors and decrease in menstrual blood PG levels, intrauterine pressure and dysmenorrheic pain.

    Menstrual cup is increasingly gaining acceptance among women to control the menstrual period. The majority of brands advocate that these devices are 100% safe to the users, notwithstanding there are some reports of rare complications associated with these devices. In this case we present a woman who developed a right renal colic using a menstrual cup. The pain was difficult to manage with conventional analgesics. The plain abdominal X-ray revealed the device in the pelvis occupying more than one third of the pelvis minor diameter and oriented to the right side. The ultrasound revealed right ureterohydronephrosis with no identifiable obstructive cause. The symptoms and the ureterohydronephrosis relieved completely after the removal of the device. Despite of being a safe device, problems with the menstrual cup could occur and we believe that the mechanism behind this clinical picture was the extrinsic compression of the right ureter by the cup. The control of the pain in this patient was challenging and we managed the problem with the device removal. The menstrual cup is gaining acceptance among women and it is important for clinicians to be aware of this device and possible complications associated with its use. Copyright © 2018 The Authors.

    Full Text Available Menstrual and reproductive history of 178 women referred to the thyroid clinic was compared with 49 healthy controls. Cases were classified as euthyroid, hypothyroid or hyperthyroid after clinical examination and after serum T3, T4, TSH measurements. Reproductive history was related chronologically to symptoms and signs of thyroid dysfunction. Only 31.8% of hypothyroid and 35.3% of hyperthyroid women had normal menstrual pattern in contrast with 56.3% of Euthyroid and 87.8% of healthy controls (p < 0.001. Reproductive failure (infertility, pregnancy wastage, failure of lactation occurred in 37.5% of hypothyroid and 36.5% of hyperthyroid cases against 16.3% of euthyroid and 16.7% of healthy controls (p < 0.05. Interestingly, in 45% of cases with menstrual abnormality, the anomaly was antecedent to other clinical features by a variable period of two months to ten years. Reproductive failure and lactation failure also preceded thyroid dysfunction or goitre. Reproductive dysfunction may therefore be considered as one of the presenting symptoms of thyroid disorders in women, keeping in mind both menstrual irregularities and lactation failure may also arise from other common or idiopathic origins. Especially in women with menstrual irregularities in the perimenopausal age if thyroid dysfunction is detected, pharmacotherapy may be a superior alternative to surgical interventions like hysterectomy.

    2012-11-01

    Full Text Available Background: Adolescents are often less informed, less experienced, and less comfortable accessing reproductive health information and services than adults. In many developing countries, a culture of silence surrounds the topic of menstruation and related issues; as a result many young girls lack appropriate and sufficient information regarding menstrual hygiene. This may result in incorrect and unhealthy behaviour during their menstrual period. Objectives: To assess and compare knowledge, belief, ideas, source of knowledge and practice of menstrual hygiene between school-going adolescents in an urban and a rural school of West Bengal, India. Methods: Cross-sectional, descriptive study was conducted among adolescent female students of Howrah district of West Bengal, India in the year 2011. Data was collected by pre-designed, pre-tested semi-structured self administered questionnaire. Results: The mean age at menarche was 12.1 years among urban and 12.2 years among the rural participants. More than 80% participants had some restrictions imposed during menstruation. Significantly higher number of urban girls had pre-menarchal knowledge on menstruation and used sanitary napkins. Conclusions: Menstrual hygiene is a vital aspect of health education for adolescent girls. For improvement of menstrual hygiene, sanitary napkins should be made universally available and affordable.

Data was collected by pre-designed, pre-tested semi-structured self administered questionnaire. Results: The mean age at menarche was 12.1 years among urban and 12.2 years among the rural participants. More than 80% participants had some restrictions imposed during menstruation. Significantly higher number of urban girls had pre-menarchal knowledge on menstruation and used sanitary napkins. Conclusions: Menstrual hygiene is a vital aspect of health education for adolescent girls. For improvement of menstrual hygiene, sanitary napkins should be made universally available and affordable.

    What is the association between perimenarchal exposure to total suspended particulate (TSP) in air, menstrual irregularity phenotypes and time to menstrual cycle regularity? Exposures to TSP during high school are associated with slightly increased odds of menstrual irregularity and longer time to regularity in high school and early adulthood. The menstrual cycle is responsive to hormonal regulation. Particulate matter air pollution has demonstrated hormonal activity. However, it is not known if air pollution is associated with menstrual cycle regularity. Cross sectional study of 34 832 of the original 116 430 women (29.91%) enrolled in 1989 from the Nurses' Health Study II (NHSII). The follow-up rate for this analytic sample was 97.76% at the 1991 survey. Annual averages of TSP were available for each year of high school attendance. We created three case definitions including high school menstrual irregularity and androgen excess. The time to menstrual cycle regularity was reported by participants as air pollution in the adolescent and early adulthood window may be especially important, given its association with phenotypes of menstrual irregularity. The data from this study agrees with existing literature regarding air pollution and reproductive tract diseases.

    Full Text Available Abstract Background Population variation in the duration and amount of menstrual bleeding has received little attention in the literature. This study describes these characteristics and investigates the distribution of self-perceived amount of menstrual bleeding according to socio-demographic, behavioral, and reproductive characteristics. Methods A community-based cross-sectional study was conducted among 18-45 years old women users of the 31 primary health care (PHC facilities in Pelotas city (Brazil. Interviews with structured questionnaire were carried out in the waiting rooms during two work shifts. Heaviness of menstrual bleeding was determined through the answer to the question: "Usually how much blood do you lose in every period?" Crude and adjusted analyses through Poisson regression took into account the aggregation per PHC facility. Results A total of 865 women were enrolled. Prevalence of heavy menstrual flow was 35.3% (95% CI 32.1-38.6%. In adjusted analyses, heavy menstrual bleeding was higher among the older, less educated and obese women, with higher number of pregnancies and who reported longer menstrual periods, extra-menstrual bleeding and clots in the flow. Use of hormonal contraceptive methods was protective against heavy menses. Conclusion Heavy menstrual bleeding is highly prevalent at the community level, and is associated with socio-demographic and anthropometric women's characteristics, as well as with duration of menstruation, extra-bleeding and presence of clots.

    During a cross sectional epidemiological survey on a general population sample, 596 fertile women underwent total serum IgE determination. They completed an interviewer-administered standardized questionnaire and were categorized according to their menstrual period. They were divided into two groups: those from days 10 to 20, who were considered to be in the periovulatory phase, and those in the other phases. IgE mean values were significantly different (p = 0.01) in the two groups: particularly, lower IgE values were found in those in periovulatory phase, after accounting for smoking habit and atopic status. By multiple regression analysis, taking into account the independent effects of menstrual period, age, smoking habit, hours of fast, skin prick test reactivity and presence of cough, significantly lower IgE values in the periovulatory phase were found. We hypothesize the possibility that a decrease of IgE concentration occurs during midcycle: a reduced immune response might facilitate the ovuli implantation. Further studies are necessary to longitudinally investigate the trend of IgE in the same women, as well as the distributions and the trends of other immunoglobulins

    The aim of this study was to examine the relationship between menses-associated health problems of women, such as premenstrual symptoms, menstrual pain and irregular menstrual cycles, and psychosocial stress. A cross-sectional study was conducted among Japanese college students, measuring psychosocial stress levels by means of IMPS (The Inventory to Measure Psychosocial Stress). A total of 264 female students (mean age 19.4 years), who were invited to participate in the study in October 2007, completed the questionnaire, which dealt with anthropometric data, lifestyle, menstrual history, and menstrual health status. Forty-three students were excluded due to missing data, and the remaining 221 were analyzed. The proportions of students who reported premenstrual symptoms, menstrual pain, and the experience of irregular menstrual cycles were 79%, 79%, and 63%, respectively. Students who reported premenstrual symptoms, menstrual pain, and the experience of irregular menstrual cycles had higher stress scores than those who did not. Multiple logistic regression analyses were used to identify independent factors associated with having premenstrual symptoms, menstrual pain, and the experience of irregular menstrual cycles. Stress score, heavy menstrual flow, and menstrual pain were significant predictors for premenstrual symptoms, while age at menarche and having premenstrual symptoms were significant predictors for menstrual pain. Both stress score and body mass index were found to be significant predictors for having experienced irregular menstrual cycles. The results suggest that psychosocial stress is independently associated with premenstrual symptoms and the experience of irregular menstrual cycles among college students, implying that changes in the functional potentiality of women as a result of stress are related with changes in their menstrual function.

    Evidence indicates that menstrual cycle phase plays a role in smoking withdrawal symptoms and craving. Stress increases these symptoms. Whether the stress regulatory mechanism is associated with menstrual phase and withdrawal symptoms is not well understood. Thirty-seven female smokers and 16 female nonsmokers were asked to complete a laboratory session. In each group, approximately half of the participants were tested when they were in the follicular phase and the other half was tested in the luteal phase. The session included resting baseline, stress, and recovery periods. Saliva samples for the measurement of cortisol and subjective measures of craving and withdrawal symptoms were collected at the end of each period. A series of repeated measures ANCOVAs found a significant smoking group x menstrual phase x sampling time interaction in cortisol levels (p < .05). Follow-up analyses indicated a reduced cortisol stress response in the luteal group relative to the follicular group in smokers (p < .02). This difference was not found in nonsmokers. Menstrual cycle phase is related to hormonal stress response and smoking withdrawal symptomatology. We show influences of the menstrual cycle phase on stress response among smokers. This is demonstrated by a reduced cortisol response to stress in the luteal group relative to the follicular group among smokers. This menstrual phase difference was not found in nonsmokers.

  8. Medical treatment for heavy menstrual bleeding

    2015-10-01

    Full Text Available Heavy menstrual bleeding, or menorrhagia, is subjectively defined as a “complaint of a large amount of bleeding during menstrual cycles that occurs over several consecutive cycles” and is objectively defined as menstrual blood loss of more than 80 mL per cycle that is associated with an anemia status (defined as a hemoglobin level of <10 g/dL. During their reproductive age, more than 30% of women will complain of or experience a heavy amount of bleeding, which leads to a debilitating health outcome, including significantly reduced health-related quality of life, and a considerable economic burden on the health care system. Although surgical treatment might be the most important definite treatment, especially hysterectomy for those women who have finished bearing children, the uterus is still regarded as the regulator and controller of important physiological functions, a sexual organ, a source of energy and vitality, and a maintainer of youth and attractiveness. This has resulted in a modern trend in which women may reconsider the possibility of organ preservation. For women who wish to retain the uterus, medical treatment may be one of the best alternatives. In this review, recent trends in the management of women with heavy menstrual bleeding are discussed.

    This study explored the relationship between early and current menstrual experiences. The primary hypothesis was that women who reported positive menarcheal experiences (including menstrual education and menarche) would tend to report positive current menstrual attitudes, experiences, and/or behaviors, and vice versa for women who reported negative menarcheal experiences. In this survey-based study, college-aged women (n = 327) were screened by completing a questionnaire concerning their menarcheal experiences. Women who had extremely negative ("negative group," n = 46) or extremely positive ("positive group," n = 38) early menstrual experiences returned to complete questionnaires concerning current menstrual attitudes, experiences, and behaviors. Early and current menstrual experiences were most strongly associated in the domain of menstrual attitudes. Women in the negative group reported more negative menstrual attitudes than did women in the positive group. There were additional associations between early menstrual experiences and measures of body image and health behaviors. Positive group participants reported more positive body image and better general health behaviors. Results suggest that early menstrual experiences may be related to menstrual experiences later in life. This study invites further investigation of the psychology of menstruation and suggests connecting menstruation with other women's health issues.

    The analgesic efficacy and tolerance of lysine clonixinate (LC) as well as LC-induced changes in menstrual prostaglandin levels were studied according to a prospective double-blind randomized crossover design, controlled with ibuprofen (I) and placebo (P). Treatment consisted in 4 consecutive phases: in the first phase, patients refrained from taking medication and during the remaining three phases, they received double-blind fixed doses of 1 tablet of lysine clonixinate 125 mg, I 400 mg or P, q.6 h. at random, three days before onset of menses and during 8 days thereafter. Controls were carried out at each menstrual cycle, assessing pain according to a scale from 0 to 4, onset of premenstrual and intramenstrual symptoms, relief of pain and occurrence of side-effects. During menstruation, patients recorded their assessments of pain in a diary and collected the whole menstrual bleeding during the first three days. The intensity of menstrual pain remained unchanged in controls upon admission (3.16) and during the phase with no treatment (3.04), but was significantly reduced with P (2.4), LC (1.79) and I (1.54). Significantly lower pain intensities compared with placebo were seen with active treatment phases. Forty-two percent of patients treated with P reported premenstrual pain which was significantly reduced to 17% with LC and to 12.5% with I. Active treatment phases revealed 21% of asymptomatic patients during premenstrual and menstrual periods and 71% (LC) and 75% (I) of cases with partial relief of pain. Patients' diaries showed significant pain reductions with LC and I, during the 1st and 2nd days compared with P; such differences were gradually reduced to nil by the 4th day. Levels of menstrual PGs changed according to pain intensity reductions from baseline (P: 29%, (NS); LC: 58% and I: 61%; both were statistically significant, p < 0.01).

    To determine the cross-sectional characteristics of menstruating girls, dysmenorrhea and the frequencies of related problems. Descripitive, cross-sectional study. Randomly selected primary, junior and high schools in the city center of Kayseri. 2000 female adolescents of ages between 9 and 18 years. We used a questionnaire addressing the epidemiological characteristics of menstruation, such as age at menarche, duration of menstrual intervals, average days of bleeding, and any menstrual problems and their frequencies. This study consists of a sufficient number of participants from all age groups. Of the participant (n= 2000) girls, 63.7% (n: 1274) had started menstruating. The mean age at menarche was 12.74 ± 1.03 years. With a prevalence of 84.8% (n: 1080), dysmenorrhea was the most prevalent menstrual problem and the average pain score was 5.87 ± 2.45. Of the menstruating girls, 34% (n: 439) used painkillers, the most commonly used was acetaminophen; during their period the prevalence of non-medical methods to relieve pain was % 35.2; the rate of seeking medical help for dysmenorrhea was 9.3 % (n: 119). In menstruating participants, 90.8 % was discussed their menstrual problems with their mothers. The rate of school absenteeism in menstruating girls was 15.9 % in general and 18 % in those with dysmenorrhea. Problems related to menstruation are common in adolescents and these problems affect their social life. In adolescent girls, the most common menstrual problem is dysmenorrhea and it affects school performance and attendance. Girls with menstrual problems showed a low rate of seeking medical help.

    Sex differences and menstrual cycle influences have been investigated in a variety of cognitive abilities, but results regarding attention are comparably sparse. In the present study, 35 men and 32 naturally cycling women completed three attention tasks, which are commonly used in neuropsychological assessment situations. All participants completed two sessions, which were time-locked to the follicular (low progesterone) and luteal cycle phase (high progesterone) in women. The results reveal higher operation speed during sustained attention in men, but no sex differences in selected and divided attention. Menstrual cycle influences were observed on accuracy in all three tasks. During divided and sustained attention, for which a male advantage was previously reported, accuracy was higher during the early follicular compared to the mid-luteal cycle phase. Furthermore, during selected and sustained attention the learning effect from the first to the second test session was higher in women who started the experiment in their luteal cycle phase. These results suggest a possible role of progesterone in modulating the ability to focus on certain stimulus aspects, while inhibiting others and to sustain attention over a longer period of time.

    To describe changes in the characteristics of women's menstrual cycles during the menopause transition and to identify whether such changes are perceived by women as being problematic. A cross-sectional descriptive study using a community-based convenience sample of 119 women aged 37-70 years. Participants completed a questionnaire to obtain data on demographic characteristics, menopausal status and changes to menstrual flow, duration, frequency and regularity. There was a common pattern of menstrual change which was of heavier, less frequent, irregular menstruation. Forty one percent of post-menopausal and 40% of women still in the menopause transition stated that, in terms of overall perception, the changes to menstruation experienced during the menopause transition were not problematic or disruptive. When specific change characteristics were examined, significant differences were found in duration of menses (p=0.014) and cycle irregularity (p=0.005) but no significant differences were found on the amount of flow (p=0.125) or frequency of cycles (p=0.142). Increased duration and increased irregularity of occurrence of each period are problematic for women going through the menopause transition, however, increased amount of menstrual flow at each period and increased frequency of cycles are not problematic changes.

    The purpose of this study was to determine the influence of menstrual phase and menstrual status on the cortisol response during 90 minutes of treadmill running at 60% VO2max. Eight eumenhorrheic athletes were tested in the early follicular (EF) (day 3-5), late follicular (LF) (day 13-15) and mid-luteal (ML) (day 22-24) phases. Six amenorrheic athletes were tested on two separate occasions. The resting cortisol levels were similar in each menstrual phase and overall a decreasing pattern of cortisol response to exercise was observed in all menstrual phases (P greater than .05). The amenorrheic athletes had a significantly greater (P less than .01) pattern of cortisol response than was observed in eumenorrheic athletes. The net increment in cortisol levels during exercise were distinctly greater (P less than .01) in amenorrheic than eumenorrheic athletes (amenorrheic: 413.8 +/- 113.1, eumenorrheic: EF: -482.8 +/- 88.3, LF: -311.8 +/- 102.1, ML: -386.3 +/- 146.2 nmol.l-1). In conclusion the cortisol levels are independent of menstrual phase. Also a larger cortisol increment is observed in amenorrheic athletes in response to prolonged submaximal exercise. The elevated cortisol levels in amenorrheics at rest and throughout exercise provides further evidence that disturbances in the hypothalamic-pituitary-adrenal function are associated with exercise-induced amenorrhea, although the site(s) of physiological disturbance have not been identified.

    The Epstein-Barr virus (EBV) latent membrane protein 1 (LMP1) contributes to oncogenic human B-cell transformation. Mouse B cells conditionally expressing LMP1 are not predisposed to B-cell malignancies, as LMP1-expressing B cells are eliminated by T cells. However, mice with conditional B-cell LMP1 expression and genetic elimination of α/β and γ/δ T cells ("CLT" mice) die early in association with B-cell lymphoproliferation and lymphomagenesis. Generation of CLT mice involves in-breeding multiple independently segregating alleles. Thus, although introduction of additional activating or knockout mutations into the CLT model is desirable for further B-cell expansion and immunosurveillance studies, doing such experiments by germline breeding is time-consuming, expensive, and sometimes unfeasible. To generate a more tractable model, we generated clonal CLT embryonic stem (ES) cells from CLT embryos and injected them into RAG2-deficient blastocysts to generate chimeric mice, which, like germline CLT mice, harbor splenic CLT B cells and lack T cells. CLT chimeric mice generated by this RAG2-deficient blastocyst complementation ("RDBC") approach die rapidly in association with B-cell lymphoproliferation and lymphoma. Because CLT lymphomas routinely express the activation-induced cytidine deaminase (AID) antibody diversifier, we tested potential AID roles by eliminating the AID gene in CLT ES cells and testing them via RDBC. We found that CLT and AID-deficient CLT ES chimeras had indistinguishable phenotypes, showing that AID is not essential for LMP1-induced lymphomagenesis. Beyond expanding accessibility and utility of CLT mice as a cancer immunotherapy model, our studies provide a new approach for facilitating generation of genetically complex mouse cancer models. ©2015 American Association for Cancer Research.

    To evaluate the agreement of risk categorization for Down syndrome screening between ultrasound scan-based gestational age (GA) and last menstrual period-based gestational age in both first and second trimesters by maternal serum markers. Data comprising 4,055 and 4,016 cases of first and second trimester screening were used. The maternal serum markers were analyzed using the ultrasound-based GA and menstrual age. The subjects whose menstrual age and ultrasound-based GA fell in different trimesters were excluded because the risk could not be calculated due to the different serum markers used in each trimester. The agreement of risk categorization for fetal Down syndrome was evaluated. The agreement of Down syndrome screening in the first and the second trimesters were 92.7% and 89%, respectively. The study found a good agreement of risk categorization by Kappa index, which was 0.615 for the overall screening. The menstrual age had a slight decrease in the detection rate and a lower false-positive rate. Menstrual age is acceptable in cases of accurate last menstrual period. However, in places where ultrasonography is not readily available, gestational age estimation by menstrual age along with clinical examination that corresponds to the gestational age can be reliable.

    Perimenstrual exacerbations of dermatoses are commonly recognized, yet our knowledge of the underlying pathophysiological mechanisms remains imperfect. Research into the effects of oestrogen on the skin has provided evidence to suggest that oestrogen is associated with increases in skin thickness and dermal water content, improved barrier function, and enhanced wound healing. Research into the effects of progesterone suggests that the presence of various dermatoses correlates with peak levels of progesterone. Dermatoses that are exacerbated perimenstrually include acne, psoriasis, atopic eczema and irritant dermatitis, and possibly also erythema multiforme. Exacerbations occur at the peak levels of progesterone in the menstrual cycle. Underlying mechanisms include reduced immune and barrier functions as a result of cyclical fluctuations in oestrogen and/or progesterone. Autoimmune progesterone and oestrogen dermatitis are the best-characterized examples of perimenstrual cutaneous reactions to hormones produced during the menstrual cycle. In this review, we describe the current understanding of the menstrual cycle, and its effect on the skin and cutaneous disorders. © 2015 British Association of Dermatologists.

  1. Heavy menstrual bleeding: An update on management.

    Davies, Joanna; Kadir, Rezan A

    2017-03-01

    Heavy menstrual bleeding (HMB) is defined as excessive menstrual blood loss (MBL) >80 mL per cycle, that interferes with a woman's physical, emotional, social wellbeing and quality of life. Aetiology is due to underlying uterine pathologies, coagulopathy, ovulation dysfunction, or iatrogenic. Up to 20% of women with HMB will have an underlying inherited bleeding disorder (IBD). Assessment of HMB should entail a menstrual and gynaecological history and a bleeding score to distinguish those women who require additional haematological investigations. A pelvic examination and ultrasound scan help to rule out presence of any underlying pathology. Management depends on the underlying cause and the woman's preference and her fertility wishes. Medical therapies include hormonal treatments; levonorgestrel-releasing intrauterine system (LNG-IUS) and combined hormonal contraceptives are most commonly used. Ulipristal acetate is an approved preoperative treatment for uterine fibroids, and has demonstrated efficacy in reducing MBL. Haemostatic therapies include tranexamic acid and DDAVP (1-deamino-8-D-arginine). DDAVP is used for HMB associated with certain IBDs. These therapies can be used in isolation or in combination with hormonal treatments. HMB associated with certain severe IBDs may require factor concentrate administration during menses to alleviate symptoms. Endometrial ablation is a minor surgical procedure that is associated with low operative morbidity and can be performed as an outpatient. Hysterectomy remains the definitive treatment of choice when medical therapies have failed and endometrial ablation is not suitable. Crown Copyright © 2017 Published by Elsevier Ltd.

    Atrazine is the most commonly used herbicide in the U.S. and a wide-spread groundwater contaminant. Epidemiologic and laboratory evidence exists that atrazine disrupts reproductive health and hormone secretion. We examined the relationship between exposure to atrazine in drinking water and menstrual cycle function including reproductive hormone levels. Women 18-40 years old residing in agricultural communities where atrazine is used extensively (Illinois) and sparingly (Vermont) answered a questionnaire (n=102), maintained menstrual cycle diaries (n=67), and provided daily urine samples for analyses of luteinizing hormone (LH), and estradiol and progesterone metabolites (n=35). Markers of exposures included state of residence, atrazine and chlorotriazine concentrations in tap water, municipal water and urine, and estimated dose from water consumption. Women who lived in Illinois were more likely to report menstrual cycle length irregularity (odds ratio (OR)=4.69; 95% confidence interval (CI): 1.58-13.95) and more than 6 weeks between periods (OR=6.16; 95% CI: 1.29-29.38) than those who lived in Vermont. Consumption of >2 cups of unfiltered Illinois water daily was associated with increased risk of irregular periods (OR=5.73; 95% CI: 1.58-20.77). Estimated "dose" of atrazine and chlorotriazine from tap water was inversely related to mean mid-luteal estradiol metabolite. Atrazine "dose" from municipal concentrations was directly related to follicular phase length and inversely related to mean mid-luteal progesterone metabolite levels. We present preliminary evidence that atrazine exposure, at levels below the US EPA MCL, is associated with increased menstrual cycle irregularity, longer follicular phases, and decreased levels of menstrual cycle endocrine biomarkers of infertile ovulatory cycles.

    Migraine is one of the most common neurological disorders in the general population. It affects 18% of women and 6% of men. In more than 50% of women migraineurs the occurrence of migraine attacks correlates strongly with the perimenstrual period. Menstrual migraine is highly debilitating, less responsive to therapy, and attacks are longer than those not correlated with menses. Menstrual migraine requires accurate evaluation and targeted therapy, that we aim to recommend in this review. Areas covered: This review of the literature provides an overview of currently available pharmacological therapies (especially with triptans, anti-inflammatory drugs, hormonal strategies) and drugs in development (in particular those acting on calcitonin gene-related peptide) for the treatment of acute migraine attacks and the prophylaxis of menstrual migraine. The studies reviewed here were retrieved from the Medline database as of June 2017. Expert opinion: The treatment of menstrual migraine is highly complex. Accurate evaluation of its characteristics is prerequisite to selecting appropriate therapy. An integrated approach involving neurologists and gynecologists is essential for patient management and for continuous updating on new therapies under development.

    Migraine is a chronic condition of recurring moderate-to-severe headaches that affects an estimated 6% of men and 18% of women. The highest prevalence is in those 18-49 years of age, generally when women menstruate. It is divided into episodic and chronic migraine depending on the total number of headache days per month being 14 or less or 15 or more, respectively. Migraine has been associated with menorrhagia, dysmenorrhea, and endometriosis, the latter particularly in chronic migraine. We conducted a questionnaire survey of 96 women with migraine, 18-45 years old, to determine the occurrence of the menstrual-cycle disorders, oligomenorrhea, polymenorrhea, and irregular cycle, and the menstruation disorders, dysmenorrhea and menorrhagia, in episodic vs chronic migraine. The prevalence of menstrual-cycle disorders in general (41.2 vs 22.2%) and dysmenorrhea (51.0 vs 28.9%) was statistically significantly higher in the women with chronic migraine than in those with episodic migraine (P ≤ 0.05) (not corrected for multiple comparisons). Whether the migraine was menstruation sensitive, that is, the headaches consistently occurred or worsened with menstruation, did not impact the prevalence of menstrual disorders. We conclude that chronic migraine is possibly more often than episodic migraine associated with menstrual-cycle disorders in general and dysmenorrhea, without impact on menstruation sensitivity of the headaches.

    Shear-wave elastography (SWE) presents quantitative data that thought to represent intrinsic features of the target tissue. Factors affecting the metabolism of the breast parenchyma as well as age, menstrual cycle, hormone levels, pregnancy and lactation, pre-compression artifact during the examination could affect these elastic intrinsic features. Aim of our study is to determine variation of fibroadenoma elasticity during the menstrual cycle (MC) by means of real-time shear-wave elastography (SWE) and identify the optimal time for SWE evaluation. Thirty volunteers (aged 20-40 years) who had biopsy-proven fibroadenoma greater than 1cm in diameter, with regular menstrual cycle and without contraceptive medication underwent SWE (ShearWave on Aixplorer, France) once weekly during MC. Statistical data were processed by using the software Statistical Package for the Social Sciences (SPSS) 19.0. A repeated measures analysis of variance was used for each lesion where the repeated factor was the elastographic measurements (premenstrual, menstrual and postmenstrual). Pillai's trace test was used. Pairwise correlation was calculated using Bonferroni correction. Values of p0.05). In this study, we found that there is significant difference between the elasticity values of fibroadenomas on premenstrual and postmenstrual period. We propose that one week after menstruation would be appropriate time to perform breast SWE. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Governments, multinational organisations, and charities have commenced the distribution of sanitary products to address current deficits in girls' menstrual management. The few effectiveness studies conducted have focused on health and education outcomes but have failed to provide quantitative assessment of girls' preferences, experiences of absorbents, and comfort. Objectives of the study were, first, to quantitatively describe girls' experiences with, and ratings of reliability and acceptability of different menstrual absorbents. Second, to compare ratings of freely-provided reusable pads (AFRIpads) to other existing methods of menstrual management. Finally, to assess differences in self-reported freedom of activity during menses according to menstrual absorbent. Cross-sectional, secondary analysis of data from the final survey of a controlled trial of reusable sanitary padand puberty education provision was undertaken. Participants were 205 menstruating schoolgirls from eight schools in rural Uganda. 72 girls who reported using the intervention-provided reusable pads were compared to those using existing improvised methods (predominately new or old cloth). Schoolgirls using reusable pads provided significantly higher ratings of perceived absorbent reliability across activities, less difficulties changing absorbents, and less disgust with cleaning absorbents. There were no significant differences in reports of outside garment soiling (OR 1.00 95%CI 0.51-1.99), or odour (0.84 95%CI 0.40-1.74) during the last menstrual period. When girls were asked if menstruation caused them to miss daily activities there were no differences between those using reusable pads and those using other existing methods. However, when asked about activities avoided during menstruation, those using reusable pads participated less in physical sports, working in the field, fetching water, and cooking. Reusable pads were rated favourably. This translated into some benefits for self

    In the lives of women, puberty is marked by the onset of menarche. From this stage onwards until menopause, reproductive health and menstrual hygiene are important aspects of women's lives. In Zambia's Western Province, the natural process of menstruation is a taboo and dealt with secretly. Information and knowledge about menstruation and menstrual hygiene among adolescent girls is inadequate. This paper explores the factors influencing the understanding, experiences and practices of menstrual hygiene among adolescent girls in Mongu District, Western Province of Zambia. An explorative study design was used by means of six focus group discussions conducted with 51 respondents, aged 13-20 years, from three secondary schools. Their age at menarche was 11-15. For data analysis thematic content analysis was used. The paper shows that the girls suffer from poor menstrual hygiene, originating from lack of knowledge, culture and tradition, and socio-economic and environmental constraints, leading to inconveniences, humiliation and stress. This leads to reduced school attendance and poor academic performance, or even drop outs, and ultimately infringes upon the girls' human rights. To address these shortcomings, a 'super setting approach' is recommended, in which a Health Promoting School could improve the girls' individual and group needs, and a community setting which would address the broader socio-economic, cultural and environmental conditions. This would enable creating a supportive environment for the girls to manage their periods. To successfully utilize the approach, all stakeholders (parents, teachers, children, governments and communities) should cooperate to generate context-specific solutions for creating safe menstrual care, and better and dignified conditions for adolescent girls. Therefore, this calls for comprehensive, strident advocacy for policy changes at national level, and mediation and involvement at community level.

    The effects of the neurohumoral status on the EEG alpha - activity indices were studied in a within-subject design with 78 women aged 18-27 years during 1-2 menstrual cycle. Psychometric and EEG indices of alpha waves basal body temperature, saliva progesterone and cortisol level were monitored every 2-3 days. Menstrual and follicular recording sessions occurred before the ovulatory temperature rise, luteal recording session--after increasing progesterone level more than 20% respect to previous day and premenstrual sessions after decreasing progesterone level more that 20% respect to previous day. The design consisted of rest and task periods EEG, EMG and ECG recordings. Half the subjects began during their menstrual phase and half began during their luteal phase. All 5 phases were compared for differences between psychometric features EEG alpha activity, EMG and ECG baseline resting levels, as well as for reactivity to cognitive task. The results showed menstrual phase differences in all psychometric and alpha EEG indices. The cognitive fluency, alpha peak frequency, alpha band width, power in alpha-2 frequency range are maximal at luteal, alpha visual activation and reactivity to cognitive task performance--at follicular phase. The hypothesis that the EEG alpha activity depends on the hormonal status supported by the positive association salivary progesterone level with the alpha peak frequency, power in the alpha-2 band and negative--with the power of the alpha-1 band. According these results, we conclude that psycho-physiological recording sessions with women might be provided with a glance to phase of menstrual cycle.

    2015-09-01

    Full Text Available Introduction: Symptoms induced by premenstrual syndrome (PMS adversely affect the women in reproduction period and decrease their quality of life. In literature, it is a common opinion thought that PMS could be associated with both sleep quality and menstrual attitudes. However, there has been no sufficient number of studies to define in what ways the PMS symptoms are correlated with sleep quality and menstrual attitudes. The objective of this study was to examine the relationship of PMS symptoms with menstrual attitude and sleep quality. Methods: The data were collected from 183 nursing students at Health School of Artvin Çoruh University by using a correlational design. Voluntary students completed a questionnaire involving socio-demographic characteristics, Premenstrual Syndrome Scale (PMSS, Menstrual Attitude Questionnaire (MAQ, and Pittsburgh Sleep Quality Index (PSQI. Results: Average age was 19.9 (1.8. The study determined a positively significant correlation between score of PMSS and mean scores of PSQI (r=0.306; P<0.001, and a negatively significant correlation between score of PMSS and total mean score of MAQ (r=-0.317; P<0.01. Similarly, multiple linear regression analysis showed that PSQI total score (​b=5.412; P<0.001 and MAQ total score (​ b=-27.455; P=0.001 significantly affected total score of PMSS.Conclusion: The intensity of PMS symptoms is associated with poor sleep quality and negative menstrual attitudes. Determining the methods of coping with PMS and strengthening the young girls on this subject may enhance their quality of future life.

    To determine the nature and prevalence of menstrual disorders among teenage girls. An observational descriptive cross-sectional study. Zagazig University Students' Hospital, Zagazig, Egypt. A representative sample of female students who attended the university pre-enrollment medical examination. Self-administered questionnaire covering items on the adolescents' demographic data and menstruation characteristics. Information about menarche, body mass index, physical exercise, cycle length and regularity, duration of menses, menstrual blood loss, dysmenorrhea, and premenstrual syndrome. A total of 285 questionnaires were analyzed. Mean age at menarche was 12.3 ± 1.5 years. Oligomenorrhea was reported by 18 participants (6.3%) and 5 others (1.8%) mentioned having polymenorrhea. Hypomenorrhea was noted in 25 students (8.8%), and hypermenorrhea was reported by 12 (4.2%). Irregular periods were mentioned by 24 students (8.4%). Dysmenorrhea was reported in 188 students (66.0%). Of these, 81 (28.4%) graded their pain as mild, 69 (24.2%) as moderate, and 38 (13.3%) as severe. Premenstrual syndrome was mentioned by 160 girls (56.1%). Consulting somebody regarding their menstrual problems was reported by 36 students (12.6%). Our results are not greatly different from those in other parts of the world. Data on nature and prevalence of menstrual disorders and their effect on young women's health status, quality of life, and social integration suggest that management of these disorders should be given more attention within the available reproductive health care programs. Further research into prevalence of and risk factors for menstrual disorders and their morbidity is warranted and anxiously awaited.

    2010-06-16

    The first menstrual cycles following menarche are often caracterized by irregular and/or heavy bleeding. The adolescent patient may be worried by these episodes of bleeding. In 50-80% of cases these are anovulatory bleeding due to the immaturity of the gonadotrophic axis. Nevertheless pathologies such as von Willebrand disease, genital infection, polycystic ovary syndrom, eating disorders, a tumor or a pregnancy may be diagnosed by bleeding abnormalities. The challenge for the physician is to distinguish between bleeding abnormalities secondary to anovulation and pathologies where investigations and specific follow-up is mandatory. Adolescents who experience abnormal bleeding must be counceled according to their perceptions and expectations.

    Epstein Barr virus (EBV) sequence variation is thought to contribute to Burkitt lymphoma (BL), but lack of data from primary BL tumors hampers efforts to test this hypothesis. We directly sequenced EBV from 12 BL biopsies from Ghana, Brazil, and Argentina, aligned the obtained reads to the wild-type (WT) EBV reference sequence, and compared them with 100 published EBV genomes from normal and diseased people from around the world. The 12 BL EBVs were Type 1. Eleven clustered close to each other and to EBV from Raji BL cell line, but away from 12 EBVs reported from other BL-derived cell lines and away from EBV from NPC and healthy people from Asia. We discovered 23 shared novel nucleotide-base changes in the latent membrane protein (LMP)-1 promoter and gene (associated with 9 novel amino acid changes in the LMP-1 protein) of the 11 BL EBVs. Alignment of this region for the 112 EBV genomes revealed four distinct patterns, tentatively termed patterns A to D. The distribution of BL EBVs was 48%, 8%, 24% and 20% for patterns A to D, respectively; the NPC EBV's were Pattern B, and EBV-WT was pattern D. Further work is needed to investigate the association between EBV LMP-1 patterns with BL.

    LMP (Locational marginal price) calculation is a serious impediment in distribution operation when private DG (distributed generation) units are connected to the network. A novel policy is developed in this study to guide distribution company (DISCO) to exert its control over the private units when power loss and green-house gases emissions are minimized. LMP at each DG bus is calculated according to the contribution of the DG to the reduced amount of loss and emission. An iterative algorithm which is based on the Shapley value method is proposed to allocate loss and emission reduction. The proposed algorithm will provide a robust state estimation tool for DISCOs in the next step of operation. The state estimation tool provides the decision maker with the ability to exert its control over private DG units when loss and emission are minimized. Also, a stochastic approach based on the PEM (point estimate method) is employed to capture uncertainty in the market price and load demand. The proposed methodology is applied to a realistic distribution network, and efficiency and accuracy of the method are verified. - Highlights: • Reduction of the loss and emission at the same time. • Fair allocation of loss and emission reduction. • Estimation of the system state using an iterative algorithm. • Ability of DISCOs to control DG units via the proposed policy. • Modeling the uncertainties to calculate the stochastic LMP.

    Previous studies of the relationship between the menstrual phases and smoking behavior have been problematic, so the association of menstrual phases with smoking behavior and correlations among smoking, psychological and physical conditions in each phase of the menstrual cycle are unclear. To accurately examine the association between menstrual phases and the amount of smoking (number of cigarettes smoked and breath CO concentration), craving of smoking on visual analogue scale (VAS), depression in the Center for Epidemiologic Studies Depression (CES-D) Scale, and menstrual phase-associated symptoms in the Menstrual Distress Questionnaire (MDQ), we improved various methodological issues, specifically, 1) Ovulation was confirmed by measuring the basal body temperature and identifying a urinary luteinizing hormone (LH) surge in two cycles; 2) The menstrual, follicular, and luteal phases were clearly defined for subjects with different menstrual cycles; 3) The breath CO concentration was measured every day. A notice was posted on public bulletin boards to recruit research subjects and twenty-nine young Japanese women smokers aged 19 to 25 years old were analyzed. The number of cigarettes smoked was greater and the CO concentration was higher in the luteal phase than in the follicular phase. The levels of craving for smoking (VAS), depressiveness (CES-D), and menstrual phase-associated symptoms (MDQ) in the menstrual and luteal phases were higher than those in the follicular phase. The mean score for CES-D was 16 points (the cut-off value in screening for depression) or higher in the menstrual (16.9 ± 8.2) and luteal phases (17.2 ± 8.4).The number of cigarettes smoked and CO concentration were significantly correlated with the levels of craving for smoking, depressiveness, and menstrual phase-associated symptoms in all phases except for MDQ scores in follicular phase. The amount of smoking in the luteal phase was most strongly correlated with these symptoms

    Perceptions of menstruation by media discourses portray this bodily function to be messy, inconvenient, and as an unnecessary phenomenon to be controlled or possibly eliminated. Commercials shown on YouTube targeted toward young women suggest that having a monthly period is not healthy and a lifestyle that is menses free is both pharmacologically available and recommended in order to live a fuller life. We explored the meanings attached to online menstrual suppression commercials with 10 women aged between 18 and 25. In-depth open-ended interviews were conducted over a 10-month period in 2014 after each participant viewed three menstrual suppression online advertisements. Feminist critical discourse was used for analysis with both authors coding for inter-rater reliability recognizing how our age difference and relationship as mother and daughter informed our interpretation. An overarching theme of tension emerged from the interviews with participants feeling detached due to the gendered stereotypes the commercials used to frame menstruation as compared to their own lived experience. Meanings associated with the menstrual suppression commercials were contrary to the participants' lived experience of menstruation as a healthy process not a detrimental one to their well-being as suggested by the commercials. Subliminal messages within the advertisements were identified as reinforcing gender bias and prejudices, including those associated with femininity. Despite attempting to emulate popular culture, the menstrual suppression advertisements were largely dismissed by this group of participants as undermining their intelligence and of intentionally creating divisive binaries between groups of women. This study suggests that historical bias and stereotypical prejudices were identified by this group of young women within the marketing of menstrual suppression products and, as such, were dismissed as inauthentic to the menstruation experience reflecting a form of

    There is no data on menstrual cyclicity post oral contraceptive (OC) withdrawal with nonhormonal options in PCOS patients. OC could affect obesity, insulin and gonadotropins factors integral to pathogenesis of PCOS, thereby adversely affecting the HPG axis. Menstrual cycles of PCOS patients were retrospectively studied post OCP. Patients developing regular versus irregular cycles post OC were compared. Forty-eight PCOS patients were followed for an average of 1.9 years post OC. Thirty-six (75%) achieved regular cycles over a period of one year with other nonhormonal options like spironolactone and metformin. Seven patients required no treatment. Patients who continued to have irregular cycles had a longer pre OC cycle length (p PCOS may not require any treatment post OC.

    Migraine is a common headache disorder that affects mostly women. In half of these, migraine is menstrually associated, and ranges from completely asymptomatic to frequent pain throughout pregnancy. The aim of the study was to define the pattern (frequency, intensity, analgesics use) of migrainous headaches among women with and without menstural migraine (MM) during pregnancy, and define how hormonally-related factors affect its intensity. The analysis was based upon data from 280 women, 18.6% of them having a self-reported MM. Women with MM described a higher headache intensity during early pregnancy and postpartum compared those without MM, but both groups showed improvement during the second half of pregnancy and directly after delivery. Hormonal factors and pre-menstrual syndrome had no effect upon headache frequency, but may affect headache intensity. Individual treatment plan is necessary for women with migrainous headaches during pregnancy, especially for those suffering highest symptoms load.

    The results of a survey of 1377 young Australian women aged 14 to 19 years, conducted to determine their attitudes, state of knowledge and practices with regard to menstruation, are presented. The young women, as a group, lacked sufficient information about menstruation, about the time of ovulation, about menstrual discharge, and about the use of tampons. A high proportion (80%) considered menstruation to be inconvenient or embarrassing. Certain measures aimed at remedial action are suggested.

    Managing menses is a challenge for women in developing countries. Duet is a cervical barrier being developed for contraception and STI prevention. We explored the hypothetical acceptability of using Duet as a menstrual cup, among Zimbabwean women. A survey and focus group discussions (FGD) were conducted with 43 women aged 18-45 years to gain information about their menstrual practices and attitudes regarding the use of Duet for menstrual protection. All 43 women reported that if Duet were available, they would "definitely" try it, and that it was "very important" that Duet is low cost and easy to clean; 86% reported that using it would make a difference in their lives. FGD findings highlighted unhygienic practices due to the lack of affordable options for menstrual management and a genuine interest in Duet, including its potential use for multiple purposes (contraception, disease prevention and menstrual protection). Accessing affordable and hygienic menstrual protection was a problem for these Zimbabwean women. Duet appeared acceptable and it would be feasible to conduct a user-acceptability study of Duet as a menstrual cup in Zimbabwe.

    Menstrual regulation has been legal in Bangladesh since 1974, but the use of medication for menstrual regulation is new. In this study, we sought to understand women's experiences using medication for menstrual regulation in Bangladesh. We conducted 20 in-depth interviews with rural and urban women between December 2013 and February 2014. All interviews were audiotaped, transcribed, translated, computer recorded and coded for analysis. The majority of women in our study had had positive experiences with medication for menstrual regulation and successful outcomes, regardless of whether they obtained their medication from medicine sellers/pharmacies, doctors or clinics. Women were strongly influenced by health providers when deciding which method to use. There is a need to educate not only women of reproductive age, but also communities as a whole, about medication for menstrual regulation, with a particular emphasis on cost and branding the medication. Continued efforts to improve counselling by providers about the dose, medication and side-effects of medication for menstrual regulation, along with education of the community about medication as an option for menstrual regulation, will help to de-stigmatise the procedure and the women who seek it.

    Crying, a complex neurobiological behavior with psychosocial and communication features, has been little studied in relationship to the menstrual cycle. In the Mood and Daily Life study (MiDL), a community sample of Canadian women aged 18-43 years, n=76, recorded crying proneness and crying frequency daily for six months along with menstrual cycle phase information. Crying proneness was most likely during the premenstruum, a little less likely during menses and least likely during the mid-cycle phase, with statistically significant differences although the magnitude of these differences were small. By contrast, actual crying did not differ between the three menstrual cycle phases. Oral contraceptive use did not alter the relationship between menstrual cycle phase and either crying variable. A wide range of menstrual cycle phase - crying proneness patterns were seen with visual inspection of the individual women's line graphs. timing of ovulation was not ascertained. Using a three phase menstrual cycle division precluded separate late follicular and early luteal data analysis. The sample size was inadequate for a robust statistical test of actual crying. reproductive aged women as a group report feeling more like crying premenstrually but may not actually cry more during this menstrual cycle phase. Individual patterns vary substantially. Oral contraceptive use did not affect these relationships. Suggestions for future research are included. Copyright © 2016 Elsevier B.V. All rights reserved.

    The aim of this study was to teach pad replacement skills to intellectually disabled adolescent female students during their menstruation periods by demonstrating on a dummy. It may be difficult to make intellectually disabled adolescents achieve self-care during menstruation. In addition, there are difficulties experienced in explaining menstruation, such as physical changes and the practice of cleaning during this period. The study used a 'One group pretest and post-test model'. The study was performed in a special educational institution. The population consisted of 77 female students in the high school section. Calculation of a sample size was not attempted, and 54 students with no attendance issues agreed to take part in the study and were included. In this work, we found that pad replacement training significantly changed the scores of mentally disabled adolescents before and after training. Our training yielded positive results, and the population improved their skills at all stages of skill building. Training adolescents with mental disabilities helped them gain hygiene habits. Performance of these trainings occurs at the beginning of menstrual hygiene education. To achieve improved success in life, it is important that adolescents assume the responsibility of self-care and manage sustained care activity on their own. © 2016 John Wiley & Sons Ltd.

    Previous studies demonstrating changes in women's face preferences have emphasized increased attraction to cues to possible indirect benefits (e.g. heritable immunity to infection) that coincides with periods of high fertility (e.g. the late follicular phase of the menstrual cycle). By contrast, here we show that when choosing between composite faces with raised or lowered apparent health, women's preferences for faces that are perceived as healthy are (i) stronger during the luteal phase of the menstrual cycle than during the late follicular, fertile phase, (ii) stronger in pregnant women than in non-pregnant women and (iii) stronger in women using oral contraceptives than in women with natural menstrual cycles. Change in preference for male faces was greater for short- than long-term relationships. These findings indicate raised progesterone level is associated with increased attraction to facial cues associated with possible direct benefits (e.g. low risk of infection) and suggest that women's face preferences are influenced by adaptations that compensate for weakened immune system responses during pregnancy and reduce the risk of infection disrupting foetal development.

    Fluctuations in gonadal hormones over the course of the menstrual cycle are known to cause functional brain changes and are thought to modulate changes in the balance of cortical excitation and inhibition. Animal research has shown this occurs primarily via the major metabolite of progesterone, allopregnanolone, and its action as a positive allosteric modulator of the GABA A receptor. Our study used EEG to record gamma oscillations induced in the visual cortex using stationary and moving gratings. Recordings took place during twenty females' mid-luteal phase when progesterone and estradiol are highest, and early follicular phase when progesterone and estradiol are lowest. Significantly higher (∼5 Hz) gamma frequency was recorded during the luteal compared to the follicular phase for both stimuli types. Using dynamic causal modeling, these changes were linked to stronger self-inhibition of superficial pyramidal cells in the luteal compared to the follicular phase. In addition, the connection from inhibitory interneurons to deep pyramidal cells was found to be stronger in the follicular compared to the luteal phase. These findings show that complex functional changes in synaptic microcircuitry occur across the menstrual cycle and that menstrual cycle phase should be taken into consideration when including female participants in research into gamma-band oscillations. © 2018 The Authors Human Brain Mapping Published by Wiley Periodicals, Inc.

    Alcohol use has been reported to fluctuate over women's menstrual cycles (MCs), with increased intake occurring premenstrually/menstrually (phases characterized by heightened negative affect) and during the ovulatory phase (a phase characterized by positive affect). This suggests women may drink for particular emotion-focused reasons at specific points in their cycles. However, no research had yet examined MC variability in drinking motives, or links between cycle-related changes in drinking motives and alcohol consumption. Ninety-four normally cycling women (M age  = 22.9 years old, SD age  = 4.7) completed daily diary measures (via Smartphone surveys), with questions pertaining to state drinking motives and quantity of alcohol consumed for the course of a full MC. Drinking motives differed by cycle phase. Women reported a slight increase in drinking to self-medicate for negative affect premenstrually, with drinking to cope peaking in the menstrual phase and declining mid-cycle. Women reported a slight increasing trend across the cycle in social motives for drinking, while enhancement motives remained relatively stable across the cycle. Cycle-related changes in drinking motives predicted increases in the quantity of alcohol consumed. Drinking to cope with negative affect predicted a greater number of drinks menstrually (days 1-5). While social motives predicted a greater number of drinks during the follicular and ovulatory phases (days 5-16), enhancement motives were unrelated to drinking quantity across cycle phase. Clinicians should be attentive to cycle phase when treating reproductive-aged women with alcohol disorders (e.g., encouraging the use of healthier means of coping with negative affect during menses). © 2017 Wiley Periodicals, Inc.

    Successful isolation of human endometrial stem cells from menstrual blood, namely menstrual blood-derived endometrial stem cells (MenSCs), has provided enticing alternative seed cells for stem cell-based therapy. MenSCs are enriched in the self-regenerative tissue, endometrium, which shed along the periodic menstrual blood and thus their acquisition involves no physical invasiveness. However, the impact of the storage duration of menstrual blood prior to stem cell isolation, the age of the donor, the number of passages on the self-renewing of MenSCs, the paracrine production of biological factors in MenSCs and expression of adhesion molecules on MenSCs remain elusive. In this study, we confirmed that MenSCs reside in shedding endometrium, and documented that up to 3 days of storage at 4°C has little impact on MenSCs, while the age of the donor and the number of passages are negatively associated with proliferation capacity of MenSCs. Moreover, we found that MenSCs were actually immune-privileged and projected no risk of tumour formation. Also, we documented a lung- and liver-dominated, spleen- and kidney-involved organic distribution profile of MenSC 3 days after intravenous transfer into mice. At last, we suggested that MenSCs may have potentially therapeutic effects on diseases through paracrine effect and immunomodulation. © 2017 The Authors.

    To determine the prevalence of stress fractures, menstrual dysfunction and disordered eating attitudes in elite female soccer athletes. Cross-sectional descriptive study. Female soccer athletes were recruited from a national level youth soccer club, an NCAA Division I university team, and a women's professional team. Two hundred twenty female soccer athletes with a mean age of 16.4 ± 4 years and BMI of 20.8 ± 2 kg/m(2) completed the study, representing all athletes from the included teams. One-time surveys completed by the athletes. Height and weight were recorded, and body mass index (BMI) was calculated for each athlete. Athletes reported age of menarche, history of missing 3 or more menses within a 12-month period and stress fracture. The Eating Attitudes Test (EAT-26) was used to assess the athlete's body perception and attitudes toward eating. Of the 220 soccer athletes, 3 athletes (1.6%) had a low BMI for their age, and 19 (8.6%) reported stress fractures of the lower extremity. Among athletes who had reached menarche, the average onset was 13 + 1 year; menstrual dysfunction were present in 21 (19.3%). On the EAT-26, 1 player scored in the high risk range (>20) and 17 (7.7%) scored in the intermediate risk range (10-19) for eating disorders. Athletes with an EAT-26 score ≥ 10 points had a significantly higher prevalence of menstrual dysfunction in the past year compared to athletes with an EAT-26 score of less than 10 (P = .02). Elite female soccer athletes are susceptible to stress fractures and menstrual dysfunction and have delayed onset of menarche despite normal BMI and appropriate body perception and attitudes towards eating. Further studies are needed to better understand stress fracture risk in female soccer athletes and in other team sports to determine how these findings relate to long-term bone health in this population.

    Menstruation has a variable pattern within a few years of menarche which may not be well understood by many adolescent girls. Providing accurate information on menstruation is necessary to reduce anxiety, menstrual morbidity and improve reproductive health of these adolescents. To determine the age at menarche, duration of menstruation, length of menstrual cycle, regularity of menstrual cycle, prevalence of dysmenorrhoea and sources of information on menstruation. S(T) Mary's Senior Secondary School, Accra. Cross-sectional descriptive study using self-administered questionnaire. Four hundred and fifty six girls whose ages ranged from 14-19 years with mean and median ages of 16 ± 0.93 years and 16 years respectively were surveyed. Their ages at menarche ranged from 9 years to 16 years and the mean age at menarche was 12.5 ±1.28 years. Their menstrual cycle lengths ranged from 21-35 days with mean menstrual cycle length of 27.9± 0.9 days; the mode and median were both 28 days. The mean duration of menstrual flow was 4.9 days with mode and median of 5 days. Seventy one percent (n=449) had menses lasting 3-5 days while 27.2% had menses lasting over 5 days. Some 24% (n=409) had irregular menses six months after their menarche and 59.6% (n=453) were experiencing menses with clots. The prevalence of dysmenorrhoea was 74.4% (n=453). Some 80.2% (n=378) of the girls got counselling and education on care for their menses from their parents. The age at menarche and other menstrual characteristics observed in this study are similar to adolescent menstrual characteristics described by studies in other populations in the world.

    Menstrual stigma has been demonstrated in many societies. However, there is little research on menstrual attitudes in South Asia, despite religiously-based menstrual restrictions imposed on women. To understand menstrual stigma in this context, we conducted qualitative research with women in Nepal. Nepali Hinduism forbids menstruating women to enter a temple or kitchen, share a bed with a husband or touch a male relative. During menstruation, women are 'untouchable'. There has been virtually no research on how Nepali women make meaning of these practices. The current study employed focus groups and individual interviews to understand how some Nepali women experience menarche and menstrual stigma. We explored how women describe their experiences and the strategies they adopt to manage age-old stigma in a rapidly modernising society where they have multiple roles as workers, wives and mothers. Participants reported they experienced menarche with little preparation, which caused distress, and were subjected to ongoing stigmatisation as menstruating women. They described coping strategies to reduce the effects of this stigma. This study provides a unique perspective on coping with menstrual stigma in South Asia.

    The interval of peak fertility during the menstrual cycle is of limited duration, and the day of ovulation varies, even in women with fairly regular cycles. Therefore, menstrual cycle apps identifying the "fertile window" for women trying to conceive must be quite precise. A deviation of a few days may lead the couple to focus on less- or non-fertile days for sexual intercourse and thus may be worse than random intercourse. The aim of the present investigation was to develop a scoring system for rating available apps for determining the fertile window and secondarily pilot test 12 apps currently available in both German and English (consisting of 6 calendar-based apps: Clue Menstruations- und Zykluskalender, Flo Menstruationskalender, Maya-Mein Periodentracker, Menstruationskalender Pro, Period Tracker Deluxe, and WomanLog-Pro-Kalender; 2 calculothermal apps: Ovy and Natural Cycles; and 4 symptothermal apps: myNFP, Lady Cycle, Lily, and OvuView). The calendar-based apps were investigated by entering several series of cycles with varying lengths, whereas the symptom-based apps were examined by entering data of cycles with known temperature rise, cervical mucus pattern, and clinical ovulation. The main criteria for evaluating the cycle apps were as follows: (1) What methods/parameters were used to determine the fertile window? (2) What study results exist concerning that underlying method/parameters? (3) What study results exist concerning the app itself? (4) Was there a qualified counseling service? The calendar-based apps predicted the fertile days based on data of previous cycles. They obtained zero points in our scoring system, as they did not comply with any of the evaluated criteria. Calculothermal apps had similar deficits for predicting the most fertile days and produced suboptimal results (Ovy 3/30 points and Natural Cycles 2/30 points). The symptothermal apps determined the fertile days based on parameters of the current cycle: Lady Cycle scored 20

    Patient-reported outcome measures (PROMs) have the potential to be extremely valuable in the clinical care delivery for women who report heavy menstrual bleeding (HMB). Increasingly, studies on HMB have incorporated PROMs to evaluate the impact of bleeding on quality of life. These measures have included semiquantitative charts and pictograms, questionnaires to assess symptoms and impact on quality of life, and health-related quality of life questionnaires. Recent systematic reviews have highlighted inconsistency of outcome measurement across studies on HMB as a challenge limiting the interpretability of the body of literature and the ability to generate consensus on the relative effectiveness of treatment options. Consequently, research initiatives and international collaborations are working to harmonize outcome measurement. Harmonizing the use of questionnaires in research and clinical care has the potential to improve patient-centered care delivery for women with HMB and improve the generation of patient-focused evidence-based guidelines for the evaluation and treatment of HMB.

    Objective: The purpose of this study is to investigate the value of susceptibility-weighted imaging (SWI) for the evaluation of cyclic morphological and hemorrhagic changes in abdominal wall endometriomas (AWE). Materials and methods: Fourteen patients with a total of 17 lesions who were admitted with complaints of abdominal wall mass and cyclic pain were evaluated by MRI. Patients were scanned during the first three days of the menstrual cycle and during the mid-cycle phase (day 13–15). In addition to conventional images SWI was performed. The signal changes within the lesions on SWI were compared and graded on both studies. Results: There was no significant difference in the size of the lesions in the early days of the menstruation compared to the mid-menstrual period. The SWI taken on mid-cycle phase showed that the center was hyperintense and the peripheral zone was hypointense in all lesions. A signal void related to increased blood and the shrinkage of complete disappearance of hyperintensity in the venter of the lesion was seen 15 (88%) of the 17 cases on the SWI series performed during the menstrual phase scan. Conclusion: SWI is a sensitive technique and has the capability to show hemorrhage and deposition of hemosiderin within the lesions. For patients suspected with AWE, valuable diagnostic findings may be obtained if the MRI examination including SWI is performed during the early and mid phase menstrual cycle

  14. ACOG Committee Opinion No. 651: Menstruation in Girls and Adolescents: Using the Menstrual Cycle as a Vital Sign.

    Science.gov (United States)

    2015-12-01

    Despite variations worldwide and within the U.S. population, median age at menarche has remained relatively stable-between 12 years and 13 years-across well-nourished populations in developed countries. Environmental factors, including socioeconomic conditions, nutrition, and access to preventive health care, may influence the timing and progression of puberty. A number of medical conditions can cause abnormal uterine bleeding, characterized by unpredictable timing and variable amount of flow. Clinicians should educate girls and their caretakers (eg, parents or guardians) about what to expect of a first menstrual period and the range for normal cycle length of subsequent menses. Identification of abnormal menstrual patterns in adolescence may improve early identification of potential health concerns for adulthood. It is important for clinicians to have an understanding of the menstrual patterns of adolescent girls, the ability to differentiate between normal and abnormal menstruation, and the skill to know how to evaluate the adolescent girl patient. By including an evaluation of the menstrual cycle as an additional vital sign, clinicians reinforce its importance in assessing overall health status for patients and caretakers.

    No studies have specifically considered paternal understanding of menstruation. This study aimed to establish the degree of understanding of fathers of adolescent girls with menstrual symptoms relative to mothers. This is a cross-sectional survey-based study. Adolescent patients attending an outpatient gynaecology clinic for dysmenorrhoea and/or heavy menstrual bleeding (HMB) and their parents were invited to complete surveys. 60 surveys were completed (24/40 daughters, 20/40 mothers, 16/40 fathers). Surveys aimed to test parents' understanding of menstrual symptoms and potential medications, as well as fathers' concerns with their daughters' health. The fathers' knowledge of menstrual symptoms was poorer than mothers, although most knew HMB (93%) and mood swings (87%). Many parents answered 'don't know' or did not answer questions about potential consequences of medications, although parents were clearly concerned about side effects. Most fathers (80%) were open to discussing menstrual concerns with daughters; however, only 52% of daughters were open to such discussions. Of fathers, 80% felt sympathetic/concerned, 53% helpless and 13% frustrated when daughters were in pain. When asked about impacts, 93% of fathers (79% of mothers) were worried about their daughter's welfare and 60% (21%) about schooling. We present the first insight into fathers' knowledge of their daughters' menstrual health. Overall, parents have an incomplete picture of menstrual symptoms. Even in this cohort, which could be expected to be well informed due to their daughters' attendance at a tertiary hospital, it is clear that further knowledge would assist them caring for their daughters.

    This study sought to determine the relationship of bleeding disorders to iron deficiency anemia. Additionally, this study was undertaken to examine all current treatment modalities used in a menorrhagia clinic with respect to heavy menstrual bleeding management to identify the most effective options for menstrual management in the setting of an underlying bleeding disorder. DESIGN, SETTING, PARTICIPANT, INTERVENTION, AND MAIN OUTCOME MEASURES: Retrospective chart review of adolescent <21 years with heavy menstrual bleeding attending a multidisciplinary hematology-adolescent gynecology clinic. Information included demographics, bleeding diathesis, hematologic parameters, treatment, and the diagnosis was extracted from each chart. Subjects were grouped into two categories based on the diagnosis of a bleeding disorder. Hemoglobin level, iron deficiency anemia, and need for transfusion were compared between a bleeding disorder and no bleeding disorder group. Subjects were grouped into categories depending on hormonal modality and treatment success of the groups were compared. 73 subjects tested for a bleeding disorder. Of the subjects completing testing, 34 (46%) were diagnosed with a bleeding disorders. 39 (54%) subjects had heavy menstrual bleeding due to other causes. There was no significant difference in hemoglobin between those with and without a bleeding disorder. Iron deficiency anemia was significantly higher in subjects without bleeding disorder. When comparing hormone therapy success, the levonorgestrel IUD (LNG-IUD) (89%) had the highest rate of menstrual suppression followed by norethindrone acetate 5-10mg/day (83%), and the transdermal patch (80%). All subjects using both tranexamic acid and hormonal therapy had 100% achievement of menstrual suppression. A high frequency of bleeding disorder was found in those tested. Subjects with a bleeding disorder were less likely to present with severe anemia requiring blood transfusion and less likely to have iron

    Shift work disrupts the circadian rhythm and may cause menstruation disorders. This study assessed the impact of shift work on menstrual cycle in a population of Chinese nurses. Questionnaires on menstrual characteristics and shift schedules were sent to female nurses of the First Affiliated Hospital of Sun Yat-sen University (FAHSYSU) and Guanghua Hospital of Stomatology (GHHS), affiliated to Sun Yat-sen University. Part I was a cross-sectional study and included 139 nurses in GHHS who had regular 8:00-17:30 working (non-shift group), and 334 nurses from FAHSYSU who worked shifts, a response rate of 67.5 % and 59.6 %, respectively (age ≤ 50 years). Menstrual patterns were compared and age-adjusted relative risks of shift work were analyzed. Part II was a nested case-control study. Cases were nurses in Part I who had regular cycle with mean cycle length (MCL) of 25-31 days and but at least 3 days variation in MCL after starting shift work (n = 45). Controls consisted of 67 nurses with matching shift patterns and age, but no MCL changes. A control non-shift age-matched group consisted of 30 GHHS nurses with no MCL changes. A follow-up second questionnaire was sent 2 years later. In Part I, the shift group had a significantly higher proportion of nurses with menstrual cycle irregularity. The proportion of nurses with a cycle of 25-31 days decreased from 81.7 to 67.8 % after changing to shift work. Logistic regression analysis showed that night shift frequency was the only risk factor associated with cycle shortening. After adjusting for age, MCL was shorter when night work was performed > 7 times per month. In Part II, the mean change in MCL in the case group, including prolongation or shortening, was 4.115 ± 2.084 days after shift working. In the 2 years' follow-up, the MCL of the study group did not recover to the original length. Rotating shift work can increase the prevalence of menstrual cycle irregularity. Night shift frequency was

    Oestradiol has been implicated in the pathogenesis of schizophrenia. Women with schizophrenia often suffer with menstrual dysfunction, usually associated with low oestradiol levels, but whether menstrual dysfunction has an effect on their psychiatric symptoms is not well researched. The aim of this study is to document the menstrual characteristics of women with chronic schizophrenia with focus upon menstrual regularity, menstrual cycle length and menstrual symptoms. To determine which patient characteristics are associated with irregular menses and whether irregular menses are associated with the severity of psychotic symptoms, menstrual symptoms or depressive symptoms. Cross-sectional analyses using baseline data of women enrolled in a clinical trial. Inclusion criteria include Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition, Text Revision diagnosis of schizophrenia, schizoaffective or schizophreniform disorder; aged between 18 and 51 years; residual symptoms of psychosis despite treatment with a stable dose of antipsychotic medication for at least 4 weeks. Menstrual cycle characteristics including regularity, cycle length and menstrual associated symptoms were documented. Symptoms of schizophrenia were measured using Positive and Negative Syndrome Scale, cognition was measured using Repeatable Battery for the Assessment of Neuropsychological Status and depression was assessed using the Montgomery-Asberg Depression Rating Scale. Blood samples were collected at baseline for hormone assays. Of the 139 women, 77 (55.4%) had regular menses, 57 (41%) had irregular menses and 5 (3.6%) women had missing data on their menstrual cycle. Use of atypical antipsychotics associated with hyperprolactinaemia was positively associated with irregular menses (odds ratio = 4.4, 95% confidence interval = [1.8, 10.9], p = 0.001), while age more than 30 years was negatively associated (odds ratio = 0.3, 95% confidence interval = [0.1, 0.6], p = 0.004).

    Irradiation is still the treatment of choice in NPC treatment as one of highest malignancy in Indonesia as well as in Southeast Asia. Up to now there is no accurate predictor on radiation response, since that the similar histo-morphological pattern, as a well-known prognostic factor can revealed a wide range of treatment outcomes. Purpose of the study is to established the influence of EBV-LMP 1 as the most important protein expressed by EBV oncogenes in cellular behavior such as proliferation rate, tumor aggressivity in NPC and to find out the role of both, proliferation rate and EBV-LMP1 expression as a predictor on NPC radiation response. One-hundred seventy-two paraffin-embedded biopsy specimens from NPC patients were analysed flow-cytometrically to obtain the S-phase fraction value as the proliferation parameter. From this group of patients, 81 fresh specimen biopsies could be collected, and the EBV-LMP 1 expression were detected by western blotting technique (mAB S12-Karolinska Institute) could be done. Several variables such as clinical stage, pathology pattern and radiation response were also collected. The radiation responses were established clinically (by nasopharyngoscopy), by CT scanning and pathologically. Sixty-five percent of our patients belong to the T3 and T4, whereby the N2-3 group consists 75% of them. Fourteen percent of the patients are Hsu type I, 48% are Hs type II and the rest belong to Hsu type III. Our study revealed that the mean SPF value was 14.62% (10.18%, which correlated (p<0.05) with the tumor and nodal sizes). The rate of positive expression of the EBV-LMP1 was 50%, and did not show a correlation with the proliferation activity as well as the radiation response. However, it showed a significant correlation with the tumor and nodal size. There was a significant correlation between this proliferation value with the radiation response calculated by both, bivariate as well as by multivariate analysis. The complete and incomplete

    Differences in ethanol pharmacokinetics within the menstrual cycle have previously been reported and attributed to variations in body composition, hormonal influences and gastric emptying. To establish the role of the menstrual cycle in ethanol pharmacokinetics associated with changes in body composition, ethanol blood concentrations were measured in nine healthy women during the midfollicular (P1, days 8-10) and midluteal (P2, days 22-24) phases of the menstrual cycle after a postprandial oral ethanol dose (0.3 g kg(-1)). Total body water was assessed by dual-energy x-ray densitometry (DEXA) on both occasions. Median total body water did not vary during either phase of the menstrual cycle (P1 = 54.54%, P2 = 54.66%; P = 0.9296). Median area under the ethanol concentration-time curve (AUC) was lower during P1 (215.33 mg.h dl(-1)) than during P2 (231.33 mg.h dl(-1))(P = 0.8253). No significant differences were found on ethanol pharmacokinetics in either phase of the menstrual cycle.

    Long and irregular menstrual cycles, a hallmark of polycystic ovary syndrome (PCOS), have been associated with higher androgen and lower sex hormone binding globulin levels and this altered hormonal environment may increase the risk of specific histologic subtypes of ovarian cancer. We investigated whether menstrual cycle characteristics and self-reported PCOS were associated with ovarian cancer risk among 2,041 women with epithelial ovarian cancer and 2,100 controls in the New England Case-Control Study (1992-2008). Menstrual cycle irregularity, menstrual cycle length, and PCOS were collected through in-person interview. Unconditional logistic regression models were used to calculate odds ratios (OR) and 95% confidence intervals (95% CIs) for ovarian cancer risk overall, and polytomous logistic regression to evaluate whether risk differed between histologic subtypes. Overall, we observed no elevation in ovarian cancer risk for women who reported periods that were never regular or for those reporting a menstrual cycle length of >35 days with ORs of 0.87 (95% CI = 0.69-1.10) and 0.83 (95% CI = 0.44-1.54), respectively. We observed no overall association between self-reported PCOS and ovarian cancer (OR = 0.97; 95% CI = 0.61-1.56). However, we observed significant differences in the association with menstrual cycle irregularity and risk of ovarian cancer subtypes (p heterogeneity  = 0.03) as well as by BMI and OC use (p interaction  < 0.01). Most notable, menstrual cycle irregularity was associated with a decreased risk of high grade serous tumors but an increased risk of serous borderline tumors among women who had never used OCs and those who were overweight. Future research in a large collaborative consortium may help clarify these associations. © 2016 UICC.

    Full Text Available O Transtorno Disfórico Pré-menstrual (TDPM é caracterizado por uma constelação de sintomas emocionais e alterações comportamentais, que se manifesta com um padrão temporal cíclico em associação com o período pré-menstrual. A validade de uma categoria diagnóstica psiquiátrica distinta para TDPM ainda é uma questão controversa. Entretanto, inúmeros estudos têm documentado uma associação específica entre mudanças pré-menstruais e transtornos depressivos. A presente revisão tem como objetivo sintetizar os resultados a respeito da semelhança dos sintomas depressivos no TDPM e nos transtornos depressivos, co-morbidade, história familiar e variáveis biológicas. Evidências de que os sintomas pré-menstruais seriam expressão de vulnerabilidade ao desenvolvimento de estados disfóricos (depressão e ansiedade, assim como as implicações diagnósticas dessa proposta são comentados.Premenstrual Dysphoric Disorder (PMDD is characterised by a myriad of emotional symptoms and behavioural alterations, which occur with a cyclic temporal pattern associated with the pre-menstrual period. The validity of an isolated psychiatric diagnostic category for PMDD remains controversial. However, research results have been showing a specific association between pre-menstrual changes and depressive disorder. The present review has as objective to sintethise the results on similarity between depressive symptoms in PMDD and in the depressive disorders, comorbidity, family history and biological variables. Evidences suggesting that the pre-menstrual symptoms would be expression of a vulnerability to the development of dysphoric states (depression and anxiety as well as diagnostic implications of such proposals are discussed.

    Knowledge is needed about what women generally experience (behavior and beliefs about sexual, personal, social, and dietary factors) during menstruation as baseline data. Data were obtained from a WHO non nationally representative sample of 5322 parous women from 14 cultural groups between 1973 to 1980 and a subsample of 500 women with detailed daily diaries from 10 countries (Egypt, India, Indonesia, jamaica, Korea, Mexico, Pakistan, Philippines, UK, and Yugoslavia). This study identified and analyzed 1) critical variables through principal component analysis and varimax rotation, 2) clusters of types of women with particular menstrual experiences and particular beliefs, and 3) the relationship between demographic variables and the 2 resultant cluster and the relationship between beliefs and experiences. Factor analysis resulted in the identification of 6 factors and 13 variables which accounted for more than 65% of the variance: amount of bleeding, activity during the last menstrual period, mood during last menstrual period, discomfort during last menstrual period, predictability, and blood characteristics (smell and color). Beliefs that explained more than 53% of the estimated variance were bathing behavior during menstruation, fertility and femininity issues, interpretations and implications of menstruation, and beliefs about not washing hair or body during menstruation. Alpha estimates of reliability for the belief ranged from .33 to .73, and for behavior the range was .40 to .59. The cluster analysis of type of persons identified 3 groups of women: type I (26.4%) who experienced low blood loss the first day and had a long duration of bleeding; type II (52.3%) who had a short duration of bleeding; and type III (21.2%) who had the heaviest bleeding and longest duration of bleeding. The cluster analysis of women's belief types indicated 9 profiles. For instance, Type 2 women tended to believe that menstruation is dirty but prefer more blood loss. Belief Profiles

    To summarize and evaluate evidence for the effect of yoga on menstrual disorders. PubMed, CINAHL/MEDLINE, Web of Science, AMED, and Scopus were searched for English-language literature relevant to the review question. All primary research studies were included. Fifteen studies described in 18 papers were included in the review. A range of yoga interventions were used. Some studies used a combination of Asana, Pranayama, and other yogic relaxation or meditation techniques. All included studies reported some change in their outcome measures, suggesting reduced symptoms of menstrual distress following a yoga intervention; however, the heterogeneity and intensity of the interventions and outcome measures meant that findings have limited generalizability and applicability in practice settings. Further research on the relationship between yoga practice and menstrual disorders is warranted, but there must be both consistency in the methods, measures, and quality of studies and a shift toward research on yoga practices that are replicable outside of the clinical trial setting.

    The aim of the study was to determine whether the tendencies and scope of changes in body mass, body composition and body girths across the menstrual cycle were similar or different in women of different body build. Anthropometric examinations were carried out in a group of 40 naturally regularly menstruated females practicing team sports (aged 19-21, B-v 169.3+/-6.4 cm, body mass 59.6+/-7.0 kg), in the follicular, periovulatory and luteal phases of the menstrual cycle. The phases were determined on the basis of data from two consecutive menstrual cycles taking into account the cycle’s length. To establish the type of body build, Body Mass Index, hydration status and skinfold thickness were measured. For a statistical analysis, a multiple comparisons with multiple confidence intervals were applied. The increase in body mass between the follicular and the luteal phases was observed in all groups of women, the biggest gain was recorded in slim women, who in the luteal phase weighted 0.8 kg more. The amount of fat mass increased significantly across the menstrual cycle only in more hydrated (by about 0.66 kg) and slim women (by about 0.54 kg). Significant changes between consecutive phases of the menstrual cycle in waist and hip girths, and suprailiac skinfold thickness in some groups of women also indicate influence of fatness and hydration status and slenderness. In view of the presented results, the body build seems important for an analysis of the pattern of each component’s changes across the menstrual cycle, especially for female athletes. Certain changes can be seen only in some groups of women, therefore somatic features can be considered as a predictor of the intensity of changes.

    Full Text Available Normal physiological variables, such as age and gender, contribute to alterations in circulating microRNA (miRNA expression levels. The changes in the female body during the menstrual cycle can also be reflected in plasma miRNA expression levels. Therefore, this study aimed to determine the plasma miRNA profile of healthy women during the menstrual cycle and to assess which circulating miRNAs are derived from blood cells. The plasma miRNA expression profiles in nine healthy women were determined by quantitative real time PCR using Exiqon Human Panel I assays from four time-points of the menstrual cycle. This platform was also used for studying miRNAs from pooled whole blood RNA samples at the same four time-points. Our results indicated that circulating miRNA expression levels in healthy women were not significantly altered by the processes occurring during the menstrual cycle. No significant differences in plasma miRNA expression levels were observed between the menstrual cycle time-points, but the number of detected miRNAs showed considerable variation among the studied individuals. miRNA analysis from whole blood samples revealed that majority of miRNAs in plasma are derived from blood cells. The most abundant miRNA in plasma and blood was hsa-miR-451a, but a number of miRNAs were only detected in one or the other sample type. In conclusion, our data suggest that the changes in the female body during the menstrual cycle do not affect the expression of circulating miRNAs at measurable levels.

    Full Text Available Background: Tubal ligation (TL is recommended for women who have completed their family planning. The existence of the menstrual disorders following this procedure has been the subject of debate for decades. This study was conducted to identify the relationship between tubal ligation and menstrual disorders. Materials and Methods: A historical cohort study was carried out on 140 women undergoing tubal ligation (TL group and on 140 women using condom as the main contraceptive method (Non-TL group. They aged between 20 and 40 years and were selected from a health care center in Rudsar, Guilan Province, Iran, during 2013-2014. The two groups were comparable in demographic characteristics, obstetrical features and menstrual bleeding pattern using a routine questionnaire. A validated pictorial blood loss assessment chart (PBLAC was also used to measure the menstrual blood loss. Results: Women with TL had more menstrual irregularity than those without TL (24.3 vs. 10%, P=0.002. Women with TL had more polymenorrhea (9.3 vs. 1.4%, P=0.006, hypermenorrhea (12.1 vs. 2.1%, P=0.002, menorrhagia (62.9 vs. 22.1%, P<0.0001 and menometrorrhagia (15.7 vs. 3.6%, P=0.001 than those without TL. There is a significant difference in the PBLAC score between women with and without TL (P<0.0001. According to logistic regression, age odds ratio [(OR=1.08, confidence interval (CI:1.07-1.17, P=0.03], TL (OR=5.95, CI:3.45-10.26, P<0.0001 and cesarean section (OR=2.72, CI:1.49-4.97, P=0.001 were significantly associated with menorrhagia. Conclusion: We found significant differences in menstrual disorders between women with and without TL. Therefore, women should be informed by the health providers regarding the advantages and disadvantages of TL before the procedures.

  13. Cognitive Performance in College Women Throughout the Menstrual Cycle

    Full Text Available To determine whether fluctuations of estrogen levels across the menstrual cycle influence cognitive performance, 13 university women between 20 and 23 years old were tested in four cognitive tasks; verbal memory, visuospatial ability, short term memory and visuo-motor coordination, three times across a menstrual cycle. Radioimmunoassay tests were performed in order to determine the hormonal state. Significant differences were not found in visuo-spatial ability and visuo-motor coordination performance, but results suggest a better verbal memory performance associated with high estrogen levels; short term memory performance didn’t show to be sensitive to fluctuations in estrogen levels.

    2018-06-01

    Management of heavy menstrual bleeding (HMB) in a woman with a history of thrombosis, or who is otherwise at high risk of thrombosis, or who takes medications for anticoagulation can present a challenge to health care providers. The goal of treating HMB is to reduce menstrual blood loss. First-line therapy is typically hormonal, and hormonal therapy can be contraindicated in women with a history of thrombosis unless they are on anticoagulation. As 70% of women on anticoagulation experience HMB, successful management of HMB may involve a modification in the anticoagulation or antiplatelet regimen, hormonal therapy tailored to the patient's situation, and/or surgical therapy.

    To what degree resting state fMRI is stable or susceptible to internal mind states of the individual is currently an issue of debate. To address this issue, the present study focuses on sex differences and investigates whether resting state fMRI is stable in men and women or changes within relative short-term periods (i.e., across the menstrual cycle). Due to the fact that we recently reported menstrual cycle effects on cognitive control based on data collected during the same sessions, the c...

    2015-01-01

    Full Text Available Objective. To study the efficacy and safety of tactile electrosurgical ablation (TEA in stopping a persistent attack of abnormal uterine bleeding not responding to medical and hormonal therapy. Methods. This is a case series of 19 cases with intractable abnormal uterine bleeding, who underwent TEA at the Women’s Health Center of Assiut University. The outcomes measured were; patient’s acceptability, operative time, complications, menstrual outcomes, and reintervention. Results. None of the 19 counseled cases refused the TEA procedure which took 6–10 minutes without intraoperative complications. The procedure was successful in the immediate cessation of bleeding in 18 out of 19 cases. During the 24-month follow-up period, 9 cases developed amenorrhea, 5 had scanty menstrual bleeding, 3 were regularly menstruating, 1 case underwent repeat TEA ablation, and one underwent a hysterectomy. Conclusions. TEA represents a safe, inexpensive, and successful method for management of uterine bleeding emergencies with additional long-term beneficial effects. However, more studies with more cases and longer follow-up periods are warranted.

    2016-01-01

    Perceptions of menstruation by media discourses portray this bodily function to be messy, inconvenient, and as an unnecessary phenomenon to be controlled or possibly eliminated. Commercials shown on YouTube targeted toward young women suggest that having a monthly period is not healthy and a lifestyle that is menses free is both pharmacologically available and recommended in order to live a fuller life. We explored the meanings attached to online menstrual suppression commercials with 10 women aged between 18 and 25. In-depth open-ended interviews were conducted over a 10-month period in 2014 after each participant viewed three menstrual suppression online advertisements. Feminist critical discourse was used for analysis with both authors coding for inter-rater reliability recognizing how our age difference and relationship as mother and daughter informed our interpretation. An overarching theme of tension emerged from the interviews with participants feeling detached due to the gendered stereotypes the commercials used to frame menstruation as compared to their own lived experience. Meanings associated with the menstrual suppression commercials were contrary to the participants’ lived experience of menstruation as a healthy process not a detrimental one to their well-being as suggested by the commercials. Subliminal messages within the advertisements were identified as reinforcing gender bias and prejudices, including those associated with femininity. Despite attempting to emulate popular culture, the menstrual suppression advertisements were largely dismissed by this group of participants as undermining their intelligence and of intentionally creating divisive binaries between groups of women. This study suggests that historical bias and stereotypical prejudices were identified by this group of young women within the marketing of menstrual suppression products and, as such, were dismissed as inauthentic to the menstruation experience reflecting a form of

    2011-03-01

    Low concentrations of leptin secondary to low body fat or other modulators are thought to be a key signal whereby an energy deficit suppresses the reproductive axis in exercising women resulting in functional hypothalamic amenorrhea (FHA). The purpose of this study was to first examine leptin concentrations in exercising women with and without FHA to address whether there is a threshold concentration of leptin below which reproductive function is suppressed. Secondly, we examined the role of adiposity and other possible modulators of leptin to ascertain whether leptin regulation differs depending on reproductive status. This study assessed 50 exercising, premenopausal women (aged 18-30 years) over the course of one menstrual cycle (eumenorrheic women) or one 28-day monitoring period (amenorrheic women). Quantification of daily urinary ovarian steroids and menstrual history were used to determine menstrual status. Body composition was assessed using dual energy X-ray absorptiometry, and leptin was determined by enzyme-linked immunoassay. Key modulators of leptin such as serum insulin concentration, carbohydrate intake, glucose availability, indirect indices of sympathetic nervous activity and other factors were assessed using linear regression. Percentage body fat (%BF) (21.0 ± 1.0 versus 26.8 ± 0.7%; P exercising women with amenorrhea (ExAmen; n = 24) compared with the exercising ovulatory women (ExOvul; n = 26). However, the ranges in leptin were similar for each group (ExAmen: 0.30-16.98 ng/ml; ExOvul: 2.57-18.28 ng/ml), and after adjusting for adiposity the difference in leptin concentration was no longer significant. Significant predictors of log leptin in ExAmen included %BF (β = 0.826, P exercising women, but the modulation of leptin concentrations may differ depending on reproductive status.

  1. Menarche delay and menstrual irregularities persist in adolescents with type 1 diabetes

    Full Text Available Abstract Background Menarche delay has been reported in adolescent females with type 1 diabetes (T1DM, perhaps due to poor glycemic control. We sought to compare age at menarche between adolescent females with T1DM and national data, and to identify factors associated with delayed menarche and menstrual irregularity in T1DM. Methods This was a cross-sectional study and females ages 12- 24 years (n = 228 with at least one menstrual period were recruited during their outpatient diabetes clinic appointment. The National Health and Nutrition Examination Survey (NHANES 2001-2006 data (n = 3690 for females 12-24 years were used as a control group. Results Age at menarche was later in adolescent females with T1DM diagnosed prior to menarche (12.81 +/- 0.09 years (mean+/- SE (n = 185 than for adolescent females diagnosed after menarche (12.17 0.19 years, p = 0.0015 (n = 43. Average age of menarche in NHANES was 12.27 +/- 0.038 years, which was significantly earlier than adolescent females with T1DM prior to menarche (p p = 0.77. Older age at menarche was negatively correlated with BMI z-score (r = -0.23 p = 0.0029 but not hemoglobin A1c (A1c at menarche (r = 0.01, p = 0.91. Among 181 adolescent females who were at least 2 years post menarche, 63 (35% reported usually or always irregular cycles. Conclusion Adolescent females with T1DM had a later onset of menarche than both adolescent females who developed T1DM after menarche and NHANES data. Menarche age was negatively associated with BMI z-score, but not A1c. Despite improved treatment in recent decades, menarche delay and high prevalence of menstrual irregularity is still observed among adolescent females with T1DM.

  2. Testosterone concentrations in female athletes and ballet dancers with menstrual disorders.

    2016-01-01

    Menstrual disorders are common among female athletes and ballet dancers. Endocrine changes, such as high testosterone (HT) levels and high luteinizing hormone (LH)/follicle-stimulating hormone (FSH) ratios, may suggest functional ovarian hyperandrogenism which may induce such dysfunction. The aim of this study was therefore to evaluate endocrine status in female athletes and ballet dancers with menstrual disorders. Their nutritional status and dietary habits were analysed in relation to the testosterone levels. In a cross-sectional approach, 31 female athletes (18.1 ± 2.6 years) and 21 ballerinas (17.1 ± 0.9) with menstrual disorders participated in the study. The levels of serum LH, FSH, progesterone (P), estradiol (E2), prolactin (PRL), thyroid-stimulating hormone, testosterone (T) and sex hormone-binding globulinwere measured to assess hormonal status. In addition, the free androgen index (FAI) was calculated. Nutritional status, total daily energy expenditure and nutritional habits were evaluated. Girls were assigned to one of the following groups: low testosterone (LT) level, normal testosterone level or HT level. There were significant differences between ballerinas and other female athletes in terms of testosterone levels, FAI, age at the beginning of training, length of training period and age at menarche. The PRL level was lowest in the LT group while the FAI index was highest in the HT group. Daily energy and carbohydrate intakes were significantly lower in the HT group. T levels in the study subjects were found to be associated with nutritional factors, energy availability, age at the beginning of training and frequency of training. This is the first report of HT levels being associated with the status of a female ballet dancer, the age of menarche and the length of the training history. Further research is necessary to confirm the results in a larger study group.

    2015-01-01

    Recent authors have reported a relationship between women's fertility status, as indexed by menstrual cycle phase, and conservatism in moral, social and political values. We conducted a survey to test for the existence of a relationship between menstrual cycle day and conservatism. 2213 women reporting regular menstrual cycles provided data about their political views. Of these women, 2208 provided information about their cycle date, 1260 provided additional evidence of reliability in self-reported cycle date, and of these, 750 also indicated an absence of hormonal disruptors such as recent hormonal contraception use, breastfeeding or pregnancy. Cycle day was used to estimate day-specific fertility rate (probability of conception); political conservatism was measured via direct self-report and via responses to the "Moral Foundations" questionnaire. We also recorded relationship status, which has been reported to interact with menstrual cycle phase in determining political preferences. We found no evidence of a relationship between estimated cyclical fertility changes and conservatism, and no evidence of an interaction between relationship status and cyclical fertility in determining political attitudes. Our findings were robust to multiple inclusion/exclusion criteria and to different methods of estimating fertility and measuring conservatism. In summary, the relationship between cycle-linked reproductive parameters and conservatism may be weaker or less reliable than previously thought.

  7. Characterization of chaotic dynamics in the human menstrual cycle

    2010-03-01

    The human menstrual cycle exhibits much unexplained variability, which is typically dismissed as random variation. Given the many delayed nonlinear feedbacks in the reproductive endocrine system, however, the menstrual cycle might well be a nonlinear dynamical system in a chaotic trajectory, and that this instead accounts for the observed variability. Here, we test this hypothesis by performing a time series analysis on data for 7438 menstrual cycles from 38 women in the 20-40 year age range, using the database maintained by the Tremin Research Program on Women's Health. Using phase space reconstruction techniques with a maximum embedding dimension of 6, we find appropriate scaling behavior in the correlation sums for this data, indicating low dimensional deterministic dynamics. A correlation dimension of 2.6 is measured in this scaling regime, and this result is confirmed by recalculation using the Takens estimator. These results may be interpreted as offering an approximation to the fractal dimension of a strange attractor governing the chaotic dynamics of the menstrual cycle.

    To investigate the effect of menstrual cycle states on ovarian and anabolic hormonal responses to acute resistance exercise in young women. Eight healthy women (eumenorrhea; EM) and eight women with menstrual disorders including oligomenorrhea and amenorrhea (OAM) participated in this study. The EM group performed acute resistance exercises during the early follicular (EF) and midluteal (ML) phases, and the OAM group performed the same exercises. All subjects performed three sets each of lat pull-downs, leg curls, bench presses, leg extensions, and squats at 75%-80% of one-repetition maximum with a 1-min rest between sets. Blood samples were obtained before exercise, immediately after, 30 min after, and 60 min after the exercise. In the EM group, resting serum levels of estradiol and progesterone in the ML phase were higher than those in the EF phase and higher than those in the OAM group. Serum estradiol and progesterone in the ML phase increased after the exercise but did not change in the EF phase or in the OAM group. In contrast, resting levels of testosterone in the OAM group were higher than those in both the ML and EF phases of the EM group. After the exercise, serum growth hormone increased in both the ML and EF phases but did not change in the OAM group. The responses of anabolic hormones to acute resistance exercise are different among the menstrual cycle states in young women. Women with menstrual disturbances with low estradiol and progesterone serum levels have an attenuated anabolic hormone response to acute resistance exercise, suggesting that menstrual disorders accompanying low ovarian hormone levels may affect exercise-induced change in anabolic hormones in women.

    To date, very few publications have examined the health related quality of life (HRQL) in the younger population with menstrual problems, despite their high prevalence in adolescent girls. We describe the health-related quality of life (HRQL) among adolescents with menstrual problems and identified factors that have an impact on it. The study was a questionnaire study (using PedsQL 4.0) of adolescents aged 13-18 referred to a tertiary gynecology center for menstrual problems between June 2009 and August 2010. One hundred eighty-four adolescents completed the questionnaires. The mean age was 15.10 ± 1.49 with the mean body mass index (BMI) of 22.83 ± 4.82 kg/m(2). The most common menstrual problems seen in the clinic were dysmenorrhea (38.6%) followed by heavy bleeding (33.6%), oligomenorrhea (19.6%), and amenorrhea (8.2%). The mean overall score was 70.40 ± 16.36 with 42.3% having a score below 1 standard deviation (SD) from the norms. Adolescents with dysmenorrhea had the poorest score in physical function, whereas those with amenorrhea had the lowest score in psychosocial function. Maternal parenting style, parental anxiety, adolescents' ill-health behavior, and BMI have been found to have impact on the girls' quality of life (QoL). Although menstrual problems are not life threatening, they can pose a significant impact on the quality of life of these patients. Identification of these impacts might lead to the recognition of potential services or education to improve this. Understanding the characteristics that predict QoL may help a clinician identify patients who are risk for poor QoL. Copyright © 2013 North American Society for Pediatric and Adolescent Gynecology.

    Full Text Available Este estudo de caso teve como objetivo verificar a relação do treinamento de tênis de campo com o ciclo menstrual em uma atleta com 17 anos de idade. O período de treinamento foi de 16 semanas. As avaliações motoras foram realizadas em dois momentos, no período de ovulação do ciclo menstrual da atleta investigada. Foram analisadas as capacidades motoras específicas ao tênis de campo: velocidade, potência muscular de membros superiores, potência muscular de membros inferiores e agilidade. Os resultados encontrados demonstram que houve melhora considerável em todas as variáveis. Sendo assim, sugere-se que um planejamento orientado, baseado no princípio da individualidade, poderá orientar cargas de treinos, buscando melhores resultados, entretanto são necessárias monitorações, em diferentes períodos do ciclo menstrual com uma população maior, na busca de respostas por demais fatores relacionados com a menstruação e exercício.This case study had as objective to verify the relation between tennis training and the menstrual cycle of a 17-year-old athlete. The training period lasted 16 weeks. Performance tests were carried out in two instances during the ovulation period of the menstrual cycle of the investigated athlete. Motor skills specific to tennis were analyzed: speed, arm muscle strength, leg muscle strength and agility. The results demonstrated a considerable improvement in all variables. Therefore, it is suggested that a guided plan, based of the principle of individuality, will be able to guide training loads and seek better results. However, monitoring is necessary in the different periods of the menstrual cycle, using a larger population sample, in the search for answers to other factors related to menstruation and exercise.

    To determine whether menstrual cups are a viable alternative to tampons. Randomized controlled trial. Prince George, Victoria, and Vancouver, BC. A total of 110 women aged 19 to 40 years who had previously used tampons as their main method of menstrual management. Participants were randomized into 2 groups, a tampon group and a menstrual cup group. Using online diaries, participants tracked 1 menstrual cycle using their regular method and 3 menstrual cycles using the method of their allocated group. Overall satisfaction; secondary outcomes included discomfort, urovaginal infection, cost, and waste. Forty-seven women in each group completed the final survey, 5 of whom were subsequently excluded from analysis (3 from the tampon group and 2 from the menstrual cup group). Overall satisfaction on a 7-point Likert scale was higher for the menstrual cup group than for the tampon group (mean [standard deviation] score 5.4 [1.5] vs 5.0 [1.0], respectively; P=.04). Approximately 91% of women in the menstrual cup group said they would continue to use the cup and recommend it to others. Women used a median of 13 menstrual products per cycle, or 169 products per year, which corresponds to approximately 771,248,400 products used annually in Canada. Estimated cost for tampon use was $37.44 a year (similar to the retail cost of 1 menstrual cup). Subjective vaginal discomfort was initially higher in the menstrual cup group, but the discomfort decreased with continued use. There was no significant difference in physician-diagnosed urovaginal symptoms between the 2 groups. Both of the menstrual management methods evaluated were well tolerated by subjects. Menstrual cups are a satisfactory alternative to tampons and have the potential to be a sustainable solution to menstrual management, with moderate cost savings and much-reduced environmental effects compared with tampons.

    Full Text Available Objective: To identify uterine hysteroscopic findings among patientswith prior cesarean section and whom had post-menstrual bleedingspotting type. Methods: We conducted a descriptive and prospective study between June 2008 and December 2009 involving women admitted to our clinic in Ji-Paraná (RO, Brazil, and who complained of prolonged genital bleeding after menstrual period. A total of 20 women with the simultaneous following characteristics were selected: at least one prior cesarean section, aged between 18 and 45 years, no use of hormonal contraceptives, and no history of uterine surgery that could change the cavity anatomy. All participants underwent a hysteroscopic examination. Results: During hysteroscopy, in 90% of the patients, the presence of a cesarean section scar was observed in the last third of the cervix. This scarring causes an anomaly in the uterine cavity anatomy, characterized by the viewing of an enlargement followed by a retraction of the anterior wall, which affords the presence of a pseudocavity with depth and lumen narrowing in variable degrees. Two patients did not present the pseudocavity. Conclusion: Pseudocavities in cesarean section scar are usually found in hysteroscopic examination of patients with prior cesarean section and abnormal uterine spotting.

    Wrist activity was monitored continuously for one year in a woman who went about her normal life. The year of data were analyzed for changes and rhythms--daily, weekly, menstrual, lunar, annual. For each day, average motions/5 minutes, activity onset, activity offset, alpha (duration of activity), and acrophase were measured. Periodograms and average daily wave forms were calculated. Well-defined, entrained, daily rest-activity cycles were observed throughout the year with periods close to 24 hours. There was weekend delay (0.7 hours) in onset, weekend decrease in alpha (1.0 hours), and weekend advance of acrophase (0.4 hours). Motions/5 minutes decreased 9%, onsets were 0.3 hours later, and alphas were 0.4 hours shorter on menstrual cycle days 8 through 18 which should have encompassed the time of ovulation. Lunar phase had no effect. Annual changes in onset (1.1 hours), offset (1.2 hours), and acrophase (1.1 hours) were attributed to the 1-hour change between standard and daylight savings time.

    Socioeconomic changes, as well as the development of new contraceptive modalities may influence women's preferences in the selection of a method of contraception. The aim of this study was to evaluate the knowledge, opinions and attitudes of female university students regarding the menstrual cycle, sexual health and contraception. A questionnaire-based survey was conducted among 2572 female university students in Hungary, Romania and Serbia, between November 2009 and January 2011. A higher proportion of students of health sciences than students of other faculties had appropriate knowledge of the fertile period within a menstrual cycle: 86.0%, 71.5% (p = .02) and 61.1% vs. 71.9% (p students believed in the need for monthly menstruation in order to be healthy; however, merely 30 to 40% of them wished to have monthly bleeding. In general, the respondents were aware of the importance of menstruation in relation to sexual health; however, they wished to suppress the menstruation-related symptoms. Differences in the knowledge and attitudes of female university students of the three assessed countries may be explained in part by cultural differences, and in part by the nature of their studies.

    To perform semiautomated quantitative analysis of the background enhancement (BE) in a cohort of patients with newly diagnosed breast cancer and to correlate it with mammographic breast density and menstrual cycle. Informed consent was waived after the research ethics board approved this study. Results of 177 consecutive preoperative breast magnetic resonance (MR) examinations performed from February to December 2009 were reviewed; 147 female patients (median age, 48 years; range, 26-86 years) were included. Ordinal values of BE and breast density were described by two independent readers by using the Breast Imaging Reporting and Data System lexicon. The BE coefficient (BEC) was calculated thus: (SI2 · 100/SI1) - 100, where SI is signal intensity, SI2 is the SI enhancement measured in the largest anteroposterior dimension in the axial plane 1 minute after the contrast agent injection, and SI1is the SI before contrast agent injection. BEC was used for the quantitative analysis of BE. Menstrual cycle status was based on the last menstrual period. The Wilcoxon rank-sum or Kruskal-Wallis test was used to compare quantitative assessment groups. Cohen weighted κ was used to evaluate agreement. Of 147 patients, 68 (46%) were premenopausal and 79 (54%) were postmenopausal. The quantitative BEC was associated with the menstrual status (BEC in premenopausal women, 31.48 ± 20.68 [standard deviation]; BEC in postmenopausal women, 25.65 ± 16.74; P = .02). The percentage of overall BE was higher when the MR imaging was performed in women in the inadequate phase of the cycle (quantitative BE than postmenopausal women. No association was found between BE and breast density.

    Heavy menstrual bleeding (HMB) is one of the leading causes of low quality of life and iron deficiency anemia in women. This study aimed to determine the effect of hydroalcoholic extracts of Capsella bursa-pastoris on HMB. This study is a triple-blinded, randomized clinical trial. The study was conducted in gynecology clinics affiliated to Shahid Beheshti University of Medical Sciences, Tehran, Iran. Our patients affected to a complaint of HMB. After obtaining a complete medical history of the women and filling out the demographic forms, the participants were assigned randomly into the experimental (n = 42) and control groups (n = 42). The eligible participants were given a pictorial blood loss assessment chart (PBLAC) to confirm HMB during the menstrual cycle. The experimental group received two capsules of mefenamic acid (500 mg) every 8 h and two Capsella bursa-pastoris capsules every 12 h. The intervention started from the first day of menstruation to the end of this period up to 7 days for two consecutive cycles. In the control group, the patients received mefenamic acid and placebo instead of Capsella bursa-pastoris capsules. The PBLAC score and number of bleeding days, incidence of any possible problems, as well as participant satisfaction were measured. The data were analyzed using t-test, Chi-square, repeated-measures ANOVA, and ANCOVA tests in PASW Statistics ver. 18. After the intervention, there was observed significant decrease in the amount of menstrual bleeding in both groups. However, the mean decrease in the amount of bleeding was significantly more in the Capsella bursa-pastoris group (p < 0/001). Compared with control group, hydroalcoholic extracts of Capsella bursa-pastoris capsule appeared to be effective in reducing menstrual bleeding in this study. Further research regarding the efficacy and safety of Capsella bursa-pastoris is required.

    In adolescent girls, amenorrhea is sometimes viewed as a variant of normal; in fact, however, during the first gynecologic year, the 95th percentile for cycle length is 90 days. Although early menstrual cycles are frequently anovulatory and may be somewhat irregular, girls with menses coming less frequently than every 90 days may have significant pathology associated with hypoestrogenism. Hypoestrogenism is a known risk factor for the development of osteoporosis. Causes of oligomenorrhea and amenorrhea include the relatively common conditions of hyperandrogenism, eating disorders, and exercise-induced amenorrhea, as well as uncommon conditions such as pituitary tumor, gonadal dysgenesis, and premature ovarian failure. Even functional hypothalamic oligomenorrhea has been linked to reduced bone density. Attention to menstrual irregularity and the earlier diagnosis of conditions causing it may lead to interventions that will benefit life-long bone health.

    Full Text Available Background: Menstruation and menstrual practices are still clouded by taboos and socio-cultural restrictions resulting in adolescent girls remaining ignorant of the scientific facts and hygienic health practices, which sometimes result into adverse health outcomes. Objectives: (i To elicit the beliefs, conception and source of information regarding menstruation among the study population and (ii to find out the status of menstrual hygiene among adolescent girls. Materials and Methods: A descriptive, cross-sectional study was conducted among 160 adolescent girls of a secondary school situated in the field practice area of Rural Health Unit and Training Center, Singur, West Bengal, with the help of a pre-designed and pre-tested questionnaire. Data were analyzed statistically by simple proportions. Results: Out of 160 respondents, 108 (67.5% girls were aware about menstruation prior to attainment of menarche. Mother was the first informant regarding menstruation in case of 60 (37.5% girls. One hundred and thirty-eight (86.25% girls believed it as a physiological process. Seventy-eight (48.75% girls knew the use of sanitary pad during menstruation. Regarding practices, only 18 (11.25% girls used sanitary pads during menstruation. For cleaning purpose, 156 (97.5% girls used both soap and water. Regarding restrictions practiced, 136 (85% girls practised different restrictions during menstruation. Conclusions: Menstrual hygiene, a very important risk factor for reproductive tract infections, is a vital aspect of health education for adolescent girls. Educational television programmes, trained school nurses/health personnel, motivated school teachers and knowledgeable parents can play a very important role in transmitting the vital message of correct menstrual hygiene to the adolescent girl of today.

    Animal models and a few human investigations suggest progesterone may be associated with anxiety. Progesterone naturally fluctuates across the menstrual cycle, offering an opportunity to understand how within-person increases in progesterone and average progesterone levels across the cycle correspond to women's anxiety. Across two longitudinal studies, we simultaneously modeled the between- and within-person associations between progesterone and anxiety using multilevel modeling. In Study 1, 100 Polish women provided saliva samples and reported their anxiety at three phases of the menstrual cycle: follicular, peri-ovulatory, and luteal. A significant between-person effect emerged, revealing that women with higher average progesterone levels across their cycles reported higher levels of anxiety than women with lower progesterone cycles. This effect held controlling for estradiol. In Study 2, 61 American women provided saliva samples and reported their attachment anxiety during laboratory sessions during the same three cycle phases. A significant between-person and within-person association emerged: women with higher average progesterone levels reported higher levels of attachment anxiety, and as women's progesterone levels increased across their cycles, so too did their attachment anxiety. These effects held controlling for cortisol. In sum, both studies provide support for a link between menstrual cycle progesterone levels and subjective anxiety. Copyright © 2018.

    Full Text Available Obstetric complications in women of reproductive age are often the result of puberty disorders which remain underestimated and not taken into account in pregnancy monitoring programs in such patients, leading to an increase of habitual non-carrying of pregnancy and negative obstetric effects. The objective of the research is to carry out a comprehensive multivariate assessment of the disturbances of the body adaptive processes in teenage girls, taking into account the data of anamnesis regarding the specifics of menstrual function regularization during puberty, and to determine the main factors of complicated pregnancy in this category of patients. Materials and methods. To carry out the task, 110 pregnant women with a disorder of menstrual function regularizationhave been prospectively examined (the main group; the examination was performed at the preconception stage and in the periods of 6-12, 22-24 and 32-36 weeks of pregnancy. The comparison group consisted of 30 patients with a normal menstrual cycle. In order to identify risk factors and predict complications, the odds ratio (OR and its 95% confidence interval were used. Results. Extragenital pathology plays a significant role in the formation of pathological course of puberty and obstetric complications; 87.27% ofsuch cases were demonstrated in our study. Among the disorders of the ovarian-menstrual cycle, the structural significance is characteristic to the failure of the luteal phase and anovulatory disorders (78.18% of cases.

    To what degree resting state fMRI is stable or susceptible to internal mind states of the individual is currently an issue of debate. To address this issue, the present study focuses on sex differences and investigates whether resting state fMRI is stable in men and women or changes within relative short-term periods (i.e., across the menstrual cycle). Due to the fact that we recently reported menstrual cycle effects on cognitive control based on data collected during the same sessions, the current study is particularly interested in fronto-parietal resting state networks. Resting state fMRI was measured in sixteen women during three different cycle phases (menstrual, follicular, and luteal). Fifteen men underwent three sessions in corresponding time intervals. We used independent component analysis to identify four fronto-parietal networks. The results showed sex differences in two of these networks with women exhibiting higher functional connectivity in general, including the prefrontal cortex. Menstrual cycle effects on resting states were non-existent. It is concluded that sex differences in resting state fMRI might reflect sexual dimorphisms in the brain rather than transitory activating effects of sex hormones on the functional connectivity in the resting brain.

    Cytogenetic studies of peripheral blood lymphocytes involved a sample of 30 female radiation workers with menstrual disorders from a total of 400 subjects (female physicians, laboratory technicians, and attendant personnel) included in dispensary polyclinic supervision records for a five-year period. Clinical conditions were distributed as follows: 16 patients, with oligomenorrhea; 8, with irregular bleedings; 3, with hypermenorrhea; 2, with a history of obstetric pathology; and 1, with ovarian cyst. Length of occupational experience in a radiation environment (external exposure) varied from 2 to 25 years; patient age, from 21 to 45 years. Chromosome anomalies were found in 17 of the 30 subjects investigated. Types of chromosome abnormalities detected: aneuploidy, fragments and gaps, and in one case, dicentric aberrations. Amounts of chromosome damage induced were shown to be related to years at risk. (A.B.)

    Context: Heavy menstrual bleeding (HMB) is common and incapacitating. Aberrant menstrual endometrial repair may result in HMB. The transforming growth factor (TGF)-β superfamily contributes to tissue repair, but its role in HMB is unknown. Objective: We hypothesized that TGF-β1 is important for endometrial repair, and women with HMB have aberrant TGF-β1 activity at menses. Participants/Setting: Endometrial biopsies were collected from women, and menstrual blood loss objectively measured [HMB ...

  11. Exercise training, menstrual irregularities and bone development in children and adolescents.

    Weight bearing physical activity plays an important role in bone development. This is particularly important in children and adolescents since bone mineral density reaches about 90% of its peak by the end of the second decade, and because about one quarter of adult bone is accumulated during the two years surrounding the peak bone growth velocity. Recent studies suggested that the exercise-induced increase in bone mineralization is maturity dependent, and that there is a "window of opportunity" and a critical period for bone response to weight bearing exercise during early puberty and premenarchal years. This supports the idea that increase in physical activity during childhood and adolescence can prevent bone disorders (like osteoporosis) later in life. In contrast, strenuous physical activity may affect the female reproductive system and lead to "athletic amenorrhea". The prevalence of "athletic amenorrhea" is 4-20 times higher than the general population. As a consequence, bone demineralization may develop with increased risk of skeletal fragility, fractures, vertebral instability, and curvature. Menstrual abnormalities in the female athlete result from hypothalamic suppression of the spontaneous pulsatile secretion of gonadotropin releasing hormone. Recent studies suggested that reduced energy availability (increased energy expenditure with inadequate caloric intake) is the main cause of the central suppression of the hypothalamic pituitary-gonadal axis. Therefore, effort should be made to optimize the nutritional state of female athletes, and if not successful, to reduce the training load in order to prevent menstrual abnormalities, and deleterious bone effects in particular during the critical period of rapid bone growth.

    Full Text Available Background: Menstrual cycle abnormalities have been considered a common occurrence during puberty. Numerous earlier studies have analyzed the various patterns seen in the epidemiological data regarding menstrual cycle of adolescent girls. But there is dearth of data from Rohilkhand region of central UP state. Aims: To find out the abnormal menstrual patterns among adolescent girls in Bareilly city. Materials and Methods: A cross sectional study conducted by presenting a pre-designed and pre-tested self administered questionnaire, containing questions pertaining to menstrual practices and knowledge to 994 adolescent girls of urban schools in Bareilly city. Results: Mean age of menarche was 13.11±0.95 years. 6.07% girls in the study reported cycles of abnormal lengths. This subset also had significantly higher prevalence of irregularity. Presence of irregular menses beyond 3 gynaecological years diminished the possibility of their regularization in near future. Among the girls with excessive dysmenorrhea, nearly 1/3rd had associated menstrual disturbances also. Conclusion: Incidence of irregular menstrual cycle was 20.75% and it was significantly more in oligomennorheic cycles. Among normal menstrual cycles also, presence of IMC was significantly more in adolescents having mild oligomennorhea. 6.07% of girls reported abnormal cycle lengths. 77.70% reported dysmennorhea. Chances of menstrual cycles getting regularized after 5 years of menarchy are minimal. Adequate knowledge regarding abnormal variations in the menstrual cycle pattern during adolescence may permit implementation of strategies for preventing potential reproductive and other health morbidities in adulthood.

    Previous Epstein-Barr virus (EBV) prophylactic vaccines based on the major surface glycoprotein gp350/220 as an immunogen have failed to block viral infection in humans, suggesting a need to target other viral envelope glycoproteins. In this study, we reasoned that incorporating gH/gL or gB, critical glycoproteins for viral fusion and entry, on the surface of a virus-like particle (VLP) would be more immunogenic than gp350/220 for generating effective neutralizing antibodies to prevent viral infection of both epithelial and B cell lines. To boost the humoral response and trigger cell-mediated immunity, EBV nuclear antigen 1 (EBNA1) and latent membrane protein 2 (LMP2), intracellular latency proteins expressed in all EBV-infected cells, were also included as critical components of the polyvalent EBV VLP. gH/gL-EBNA1 and gB-LMP2 VLPs were efficiently produced in Chinese hamster ovary cells, an FDA-approved vehicle for mass-production of biologics. Immunization with gH/gL-EBNA1 and gB-LMP2 VLPs without adjuvant generated both high neutralizing antibody titers in vitro and EBV-specific T-cell responses in BALB/c mice. These data demonstrate that will be invaluable not only in preventing EBV infection, but importantly, in preventing and treating the 200,000 cases of EBV-associated cancers that occur globally every year.

    The aim of this study was to evaluate the reliability of different dynamometric variables of the pelvic floor muscles (PFM) in healthy women during different periods of menstrual cycle. Vaginal dynamometric equipment was developed by the authors and its reproducibility was tested. The PFM contractions of 20 healthy women were collected by two independent examiners over three consecutive weeks, always on the same day, with a seven-day interval between readings, starting from the first day after the end of the menstrual period. For the measurements, the branch of the dynamometer was positioned first on the sagittal plane and then on the frontal plane. Baseline, peak time, maximum PFM strength, impulse contraction, and average contraction force were calculated. Reproducibility was tested using the intra-class correlation coefficient (ICC) and standard error of measurement. Repeated-measures ANOVA was used to compare the data from different days. For intra-day and inter-day reliability between examiners, all the parameters collected on the sagittal plane presented good and excellent reproducibility (ICC 2,1  = 0.60 to 0.98), whereas reproducibility on the frontal plane was respectively poor and excellent (ICC 2,1  = 0.23 to 0.97). The ANOVA revealed significant differences between sessions only for the impulse of contraction for the sagittal (P = 0.005) and frontal (P = 0.03) planes. Time and contraction force parameters of the PFM are not influenced by hormonal alterations that occur during the menstrual cycle. The impulse of contraction was the only variable to demonstrate a significant difference between the first and second week of the data collection protocol. The baseline, maximum strength value, impulse of contraction, and average contraction force variables presented good to excellent reproducibility and can be safely used as a method of PFM evaluation. © 2018 Wiley Periodicals, Inc.

    {sup 18}F-FDG PET/CT has been known a useful modality to diagnose high-glucose-using cells such as cancer cells by glucose metabolism of FDG. Mainly, FDG takes on cancer and inflammatory cells; however, there have been FDG uptakes on normal tissues by individual physiological characteristics, occasionally. Especially, in fertile females, unusual FDG uptake of breast changes as the menstrual cycle, and disturb diagnosis. Therefore, the study aimed to evaluate the change of breast FDG uptake in menstrual cycle on {sup 18}F-FDG PET/CT. 160 females (34±3.5 years old) who do not undergo a gynecologic anamnesis and have regular menstrual cycle over the previous 6 months were examined. They were divided 4 groups (each 40 patients) as flow phase, proliferative phase, ovulatory phase and secretory phase using Pregnancy Calculator 0.14. and history taking. Discovery Ste (GE Healthcare, Milwaukee, Mi, USA) was used a s PET/CT. We analyzed SUVs on a ccumulated r egion on b reast, and 3 nuclear medicine specialists did the Blind test. SUVs on the Breast were flow phase (1.64±0.25), proliferative phase (0.93±0.28), ovulatory phase (1.66±0.26) and secretory phase (1.77±0.28). It showed high uptake value in secretory, flow phase and ovulatory phase (p<0.05). In gross analysis, the accumulation of breast was divided into 3 grades as comparing with lung and liver. The breast’s uptake was equal to lung (Grade Ⅰ); between lung and liver (Grade II); equal to or greater than liver (Grade III). The results showed high uptake value in secretory, flow phase and ovulatory phase (p<0.05). In fertile females, FDG uptake of breast changed as menstrual cycle, and it available to diagnose breast disease. Therefore, we consider reducing false-negative finding of breast disease, by doing examination on appropriate period through history taking about individual menstrual cycle.

    Full Text Available BACKGROUND: We investigated the detection of chlamydia at different stages of the menstrual cycle. METHODS: Electronic medical records for women attending Melbourne Sexual Health Centre between March 2011 and 31(st December 2012, who were tested for chlamydia by nucleic acid amplification of high vaginal, cervical, or urinary samples, and who recorded a date of last normal menstrual period (LNMP between 0-28 days were included in the analysis. Logistic regression was used to calculate adjusted odds ratio (aOR and 95% confidence intervals (CI for the association of chlamydia with menstrual cycle adjusted by demographics and behavioural variables. Chlamydia and beta globin load were determined on those with stored samples. RESULTS: Of the 10,017 consultations that included a test for chlamydia and a valid LNMP, there were 417 in which chlamydia was detected. The proportion of samples with chlamydia was greater in the luteal phase (4.8%, 184/3831 than in the follicular phase (3.4%, 233/6816 both in the crude (OR 1.29 95%CI 1.1-1.6, p = 0.01 and adjusted odds ratio (aOR 1.4 (95%CI 1.1-1.8, p = 0.004. Among women using hormonal contraception, there was no significant association with the luteal phase of the menstrual cycle (aOR 1.3, 95%CI 0.9, 1.8, p = 0.18. Among women not using hormonal contraception, there was a significant association with the luteal phase (aOR 1.6, (95% CI 1.1-2.3, p = 0.007. The chlamydia load was not significantly different in the 329 positive stored samples in weeks 3 and 4 vs weeks 1 and 2 for any site (P>0.12. CONCLUSIONS: The higher detection of chlamydia detection in the luteal phase of the menstrual cycle in only those not taking hormonal contraception suggest that hormonal factors influence chlamydia detection. The absence of a significantly highly chlamydia load in women during the luteal phase raises questions about the mechanism.

    Background: Dysmenorrhea is a common gynecological condition with painful menstrual cramps of uterine origin. Prevalence of primary dysmenorrhea is not yet clearly studied in central India. Objective: To study prevalence of primary dysmenorrhea in young girls and to evaluate associated clinical markers of dysmenorrhea. Materials and Methods: In a cross-sectional study, data was collected among 310 girls (18–25 years) on age at menarche, presence and absence of dysmenorrhea, dysmenorrhea duration, pre-menstrual symptoms (PMS), family history, menses irregularities, menstrual history, severity grading using visual analogue scale (VAS) using a semi-structured questionnaire. Results: Dysmenorrhea was reported in 84.2% (261) girls and 15.8% (49) reported no dysmenorrhea. Using VAS, 34.2% of girls experienced severe pain, 36.6% moderate and 29.2% had mild pain. Bleeding duration was found to be significantly associated with dysmenorrhea (χ2 = 10.5; P dysmenorrhea (OR: 1.9; 95% CI: 1.7–3). Moreover, girls with the presence of clots had 2.07 times higher chance of having dysmenorrhea (OR: 2.07; 95% CI: 1.04–4.1) (P dysmenorrhea, 90.9% experience the condition themselves (χ2 = 11.5; P dysmenorrhea had three times greater chance of having the same problem (OR: 3.0; 95% CI: 1.5–5.8; P = 0.001). Conclusion: Dysmenorrhea is found to be highly prevalent among college going girls. Family history, bleeding duration and presence of clots were significant risk factors for dysmenorrhea.

    During the menstrual cycle, the mammary gland goes through sequential waves of proliferation and apoptosis. In mammary epithelial cells, hormonal and non-hormonal factors regulate apoptosis. To determine the cyclical effects of gonadal steroids on breast homeostasis, we evaluated the apoptotic index (AI) determined by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) staining in human mammary epithelial cells during the spontaneous menstrual cycle and correlated it with cellular proliferation as determined by the expression of Ki-67 during the same period. Normal breast tissue samples were obtained from 42 randomly selected patients in the proliferative (n = 21) and luteal (n = 21) phases. Menstrual cycle phase characterization was based on the date of the last and subsequent menses, and on progesterone serum levels obtained at the time of biopsy. The proliferation index (PI), defined as the number of Ki-67-positive nuclei per 1,000 epithelial cells, was significantly larger in the luteal phase (30.46) than in the follicular phase (13.45; P = 0.0033). The AI was defined as the number of TUNEL-positive cells per 1,000 epithelial cells. The average AI values in both phases of the menstrual cycle were not statistically significant (P = 0.21). However, the cell renewal index (CRI = PI/AI) was significantly higher in the luteal phase (P = 0.033). A significant cyclical variation of PI, AI and CRI was observed. PI and AI peaks occurred on about the 24th day of the menstrual cycle, whereas the CRI reached higher values on the 28th day. We conclude that proliferative activity is dependent mainly on hormonal fluctuations, whereas apoptotic activity is probably regulated by hormonal and non-hormonal factors

  12. Binding of the heterogeneous ribonucleoprotein K (hnRNP K to the Epstein-Barr virus nuclear antigen 2 (EBNA2 enhances viral LMP2A expression.

    Directory of Open Access Journals (Sweden)

    Henrik Gross

    Full Text Available The Epstein-Barr Virus (EBV -encoded EBNA2 protein, which is essential for the in vitro transformation of B-lymphocytes, interferes with cellular processes by binding to proteins via conserved sequence motifs. Its Arginine-Glycine (RG repeat element contains either symmetrically or asymmetrically di-methylated arginine residues (SDMA and ADMA, respectively. EBNA2 binds via its SDMA-modified RG-repeat to the survival motor neurons protein (SMN and via the ADMA-RG-repeat to the NP9 protein of the human endogenous retrovirus K (HERV-K (HML-2 Type 1. The hypothesis of this work was that the methylated RG-repeat mimics an epitope shared with cellular proteins that is used for interaction with target structures. With monoclonal antibodies against the modified RG-repeat, we indeed identified cellular homologues that apparently have the same surface structure as methylated EBNA2. With the SDMA-specific antibodies, we precipitated the Sm protein D3 (SmD3 which, like EBNA2, binds via its SDMA-modified RG-repeat to SMN. With the ADMA-specific antibodies, we precipitated the heterogeneous ribonucleoprotein K (hnRNP K. Specific binding of the ADMA- antibody to hnRNP K was demonstrated using E. coli expressed/ADMA-methylated hnRNP K. In addition, we show that EBNA2 and hnRNP K form a complex in EBV- infected B-cells. Finally, hnRNP K, when co-expressed with EBNA2, strongly enhances viral latent membrane protein 2A (LMP2A expression by an unknown mechanism as we did not detect a direct association of hnRNP K with DNA-bound EBNA2 in gel shift experiments. Our data support the notion that the methylated surface of EBNA2 mimics the surface structure of cellular proteins to interfere with or co-opt their functional properties.

    Although Attention-Deficit/Hyperactivity Disorder shows (ADHD) male predominance, females are significantly impaired and exhibit additional comorbid disorders during adolescence. However, no empirical work has examined the influence of cyclical fluctuating steroids on ADHD symptoms in women. The present study examined estradiol (E2), progesterone (P4), and testosterone (T) associations with ADHD symptoms across the menstrual cycle in regularly-cycling young women (N=32), examining trait impulsivity as a moderator. Women completed a baseline measure of trait impulsivity, provided saliva samples each morning, and completed an ADHD symptom checklist every evening for 35days. Results indicated decreased levels of E2 in the context of increased levels of either P4 or T was associated with higher ADHD symptoms on the following day, particularly for those with high trait impulsivity. Phase analyses suggested both an early follicular and early luteal, or post-ovulatory, increase in ADHD symptoms. Therefore, ADHD symptoms may change across the menstrual cycle in response to endogenous steroid changes. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Alteration of menstrual cycle by individual lifestyles and unfavorable habits may cause menstrual irregularity. We aimed to investigate the relationship between lifestyle factors and menstrual irregularity in Korean women using data from the Fifth Korea National Health and Nutrition Examination Survey (KNHANES) 2010-2012. This cross-sectional study included 3779 nondiabetic Korean women aged 19-49 years who did not take any oral contraceptives or sex hormonal compounds. We examined the association of menstrual irregularity with age, body mass index (BMI), drinking experience, and smoking habits. Age, Asian BMI, marriage status, age at menarche, and smoking habits were significantly associated with menstrual cycle irregularity (p smoking habits in middle-aged women aged 30-39 years (p smoking habits in nondiabetic Korean women. Weight loss and smoking cessation should be recommended to promote women's reproductive health.

    The influence of age on the relaxation times of normal breast parenchyma and its surrounding fatty tissue were evaluated, and the variations during a normal menstrual cycle were analyzed using an ultra low field 0.02 T imager. Thirty-nine healthy volunteers aged 21 to 59 years were examined to determine T1 and T2 relaxation times, and 8 of these volunteers were studied once weekly during one menstrual cycle. The only significant trend was an increase in the T2 of breast parenchyma with increasing age. During the menstrual cycle there was a slight but insignificant (p=0.10) increase in T1 of the breast parenchyma values during the latter half of the menstrual cycle, and a corresponding increase in T2 values between the 2nd and 3rd weeks of the menstrual cycle, which was significant.

Hypothyroidism incidence (in them was 16.9%. In addition we considered TSH range 2.5–4.0 mU/l (highly normal TSH level the extent of which was 12.3%. High extent of antibody carriage to the thyroid (31.3% in girls with irregular menses, having high blood TSH level. There were no statistical differences between the structure of menstrual dysfunction and menstrual duration depending on thyroid function (p = 0.2383, respectively, as well as the average values of estradiol levels depending on TSH level (p = 0.3213. Thus, the influence of highly normal TSH on menstrual function development in female adolescents.

  1. Linear-scaling explicitly correlated treatment of solids: Periodic local MP2-F12 method

    Theory and implementation of the periodic local MP2-F12 method in the 3*A fixed-amplitude ansatz is presented. The method is formulated in the direct space, employing local representation for the occupied, virtual, and auxiliary orbitals in the form of Wannier functions (WFs), projected atomic orbitals (PAOs), and atom-centered Gaussian-type orbitals, respectively. Local approximations are introduced, restricting the list of the explicitly correlated pairs, as well as occupied, virtual, and auxiliary spaces in the strong orthogonality projector to the pair-specific domains on the basis of spatial proximity of respective orbitals. The 4-index two-electron integrals appearing in the formalism are approximated via the direct-space density fitting technique. In this procedure, the fitting orbital spaces are also restricted to local fit-domains surrounding the fitted densities. The formulation of the method and its implementation exploits the translational symmetry and the site-group symmetries of the WFs. Test calculations are performed on LiH crystal. The results show that the periodic LMP2-F12 method substantially accelerates basis set convergence of the total correlation energy, and even more so the correlation energy differences. The resulting energies are quite insensitive to the resolution-of-the-identity domain sizes and the quality of the auxiliary basis sets. The convergence with the orbital domain size is somewhat slower, but still acceptable. Moreover, inclusion of slightly more diffuse functions, than those usually used in the periodic calculations, improves the convergence of the LMP2-F12 correlation energy with respect to both the size of the PAO-domains and the quality of the orbital basis set. At the same time, the essentially diffuse atomic orbitals from standard molecular basis sets, commonly utilized in molecular MP2-F12 calculations, but problematic in the periodic context, are not necessary for LMP2-F12 treatment of crystals.

    Full Text Available Introduction: A female encounters various menstrual disorders from puberty to menopause. We evaluated menstrual disturbances in post-menarche age and young adult age. Aim: To know the prevalence and impact of menstrual abnormalities at early adolescent and young adult age and to evaluate course of disorders identified at early adolescent age. Materials and Methods: A cross-sectional survey was carried out through self-administered questionnaire on 367 consented students at Melaka Manipal Medical College at Manipal, during December 2015- April 2016. Data were analysed by Statistical Package for the Social Sciences (SPSS 16.0 software. Results: Prevalence and pattern of menstrual disorders at early adolescent and at young adult age were noted. The mean age of menarche was 12.1 ±1.1 years. Menorrhagia was the most frequent (14.7% and 11.7% and polymenorrhea (7.6 % and 6% was least frequent menstrual disorder at adolescent age and young adult age respectively. Resolution of pubertal menstrual disorders was observed in all disorders, but noticed highest in oligomenorrhea (91%, (p-value <0.05. Prevalence of menstrual related disorder like dysmenorrhea was 88.7% at adolescent age and 67.6% at the young adult age. It was statistically significant reduction. Hindrance in academic performance and social behavior was noted more at young adult age, which was in 23.9% and 46.7% respectively (p-value <0.05. Conclusion: The most prevalent menstrual abnormality was menorrhagia at the early adolescent and the young adult age. Associated the most prevalent menstrual related symptoms were dysmenorrhea at early adolescent age, and premenstrual symptom at the young adult age. The study demonstrates the natural course (decreasing prevalence of all menstrual disorders from early adolescent to young adult age.

    The identification of subtle menstrual cycle disturbances requires daily hormone assessments. In contrast, the identification of severe menstrual disturbances, such as amenorrhea and oligomenorrhea, can be established by clinical observation. The primary purpose of this study was to determine the frequency of subtle menstrual disturbances, defined as luteal phase defects (LPD) or anovulation, in exercising women, with menstrual cycles of 26-35 days, who engage in a variety of sports, both recreational and competitive. Secondly, the prevalence of oligomenorrhea and amenorrhea was also determined via measurement of daily urinary ovarian steroids rather than self report alone. Menstrual status was documented by daily measurements of estrone and pregnanediol glucuronide and luteinizing hormone across two to three consecutive cycles and subsequently categorized as ovulatory (Ovul), LPD, anovulatory (Anov), oligomenorrheic (Oligo) and amenorrheic (Amen) in sedentary (Sed) and exercising (Ex) women. Sed (n = 20) and Ex women (n = 67) were of similar (P > 0.05) age (26.3 +/- 0.8 years), weight (59.3 +/- 1.8 kg), body mass index (22.0 +/- 0.6 kg/m2), age of menarche (12.8 +/- 0.3 years) and gynecological maturity (13.4 +/- 0.9 years). The Sed group exercised less (P exercising women experience subtle menstrual disturbances, i.e. LPD and anovulation, and that one third of exercising women may be amenorrheic. Estimates of the prevalence of subtle menstrual disturbances in exercising women determined by the presence or absence of short or long cycles does not identify these disturbances. In light of known clinical consequences of menstrual disturbances, these findings underscore the lack of reliability of normal menstrual intervals and self report to infer menstrual status.

    While ovulation is most likely to occur in adolescent girls with regular menstrual cycles, there are limited data on the incidence of ovulation in girls with irregular menstrual cycles in early postmenarcheal years. The aim of the study was to evaluate the presence of ovulation in healthy postmenarcheal girls with irregular menstrual cycles. Prospective cohort study over 12 weeks including 40 healthy postmenarcheal girls recruited from the population-based cohort of adolescents from Western Australian Pregnancy Cohort (Raine) Study with irregular menstrual cycles defined by either menstrual cycles 35 days in duration or cycle length that varied from month to month by >4 days according to menstrual diaries. Ovulation defined by urinary pregnanediol-3α-glucuronide/creatinine measurements higher than three times above minimum value obtained from 12 samples (1 per week). Forty girls (37 Caucasians) with irregular menstrual cycles aged 15.1 (median (IQR) 14.9-15.4) years who were 2.3 (1.9-3.3) years postmenarche were assessed. Urinary pregnanediol-3α-glucuronide/creatinine values identified that 33 girls (82.5%) ovulated during the 3 months of observation and 7 girls had anovulatory cycles. Menstrual diaries collected for a median (IQR) of 159 (137.5-188.2) days showed median minimal and maximum menstrual cycle duration of 24 (11.5-29) and 38.5 (35-48) days, respectively. A large proportion of healthy adolescent girls with irregular menstrual cycles are still ovulating despite irregular and infrequent menses. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    HIV acquisition in the female genital tract remains incompletely understood. Quantitative data on biological HIV risk factors, the influence of reproductive hormones, and infection risk are lacking. We evaluated vaginal epithelial thickness during the menstrual cycle in pigtail macaques (Macaca nemestrina). This model previously revealed increased susceptibility to vaginal infection during and after progesterone-dominated periods in the menstrual cycle. Nucleated and nonnucleated (superficial) epithelial layers were quantitated throughout the menstrual cycle of 16 macaques. We examined the relationship with previously estimated vaginal SHIVSF162P3 acquisition time points in the cycle of 43 different animals repeatedly exposed to low virus doses. In the luteal phase (days 17 to cycle end), the mean vaginal epithelium thinned to 66% of mean follicular thickness (days 1-16; P = 0.007, Mann-Whitney test). Analyzing 4-day segments, the epithelium was thickest on days 9 to 12 and thinned to 31% thereof on days 29 to 32, with reductions of nucleated and nonnucleated layers to 36% and 15% of their previous thickness, respectively. The proportion of animals with estimated SHIV acquisition in each cycle segment correlated with nonnucleated layer thinning (Pearson r = 0.7, P layer thinning (Pearson r = 0.6, P = 0.15). These data provide a detailed picture of dynamic cycle-related changes in the vaginal epithelium of pigtail macaques. Substantial thinning occurred in the superficial, nonnucleated layer, which maintains the vaginal microbiome. The findings support vaginal tissue architecture as susceptibility factor for infection and contribute to our understanding of innate resistance to SHIV infection.

    Estradiol production varies cyclically, changes in levels are hypothesized to affect the voice. The main objective of this study was to investigate vocal acoustic and auditory-perceptual characteristics during fluctuations in the levels of the hormone estradiol during the menstrual cycle. A total of 44 volunteers aged between 18 and 45 were selected. Of these, 27 women with regular menstrual cycles comprised the test group (TG) and 17 combined oral contraceptive users comprised the control group (CG). The study was performed in two phases. In phase 1, anamnesis was performed. Subsequently, the TG underwent blood sample collection for measurement of estradiol levels and voice recording for later acoustic and auditory-perceptual analysis. The CG underwent only voice recording. Phase 2 involved the same measurements as phase 1 for each group. Variables were evaluated using descriptive and inferential analysis to compare groups and phases and to determine relationships between variables. Voice changes were found during the menstrual cycle, and such changes were determined to be related to variations in estradiol levels. Impaired voice quality was observed to be associated with decreased levels of estradiol. The CG did not demonstrate significant vocal changes during phases 1 and 2. The TG showed significant increases in vocal parameters of roughness, tension, and instability during phase 2 (the period of low estradiol levels) when compared with the CG. Low estradiol levels were also found to be negatively correlated with the parameters of tension, instability, and jitter and positively correlated with fundamental voice frequency.

    This study aimed to examine the combined effects of menstrual cycle phase and moment of day on female soccer players' performances in the five-jump test (5JT), the repeated shuttle-sprint ability test (RSSA), and the Yo-Yo intermittent recovery test level 1 (YYIRT1). Eleven eumenorrheic Tunisian high-level soccer players volunteered to participate. Each subject individually participated in three testing periods: one in the early follicular phase (menses), one in the late follicular phase, and another in the luteal phase. In each period, two test sessions were conducted: one at 07:30 and another at 17:30. The testing routines included the 5JT, the RSSA, and the YYIRT1. None of the measured variables were altered due to menstrual cycle phase (all P>0.05). Mean time during RSSA was significantly lower in the afternoon session compared to the morning session (8.48±0.27 s and 8.77±0.34 s, respectively, P<0.001), while 5JT performance was significantly higher in the afternoon compared to the morning (9.08±0.58 m and 8.60±0.56 m, respectively, P<0.001). Soccer-specific endurance as well as jumping and repeated sprinting ability of Tunisian female high-level soccer players are not affected due to menstrual cycle phase neither in the morning nor in the afternoon.

    Full Text Available Background. Limited scientific evidence supports the positive effects of traditional Chinese medicine (TCM for treating dysmenorrhea. Thus, an observation period of 3 months could verify the ancient indication that TCM treatments effectively alleviate menstrual cramps in women with primary dysmenorrhea or endometriosis. Methods. A prospective, nonrandomized study (primary dysmenorrhea and endometriosis groups was conducted in women with dysmenorrhea for more than three consecutive menstrual cycles. All patients received TCM prescriptions based on bian zheng lun zhi theory 14 days before menstruation for a period of 12 weeks. Pain intensity was evaluated using a 10-cm visual analogue scale and two validated questionnaires (the Menstrual Distress Questionnaire and the World Health Organization Quality of Life questionnaire. Results. Of the initial 70 intent-to-treat participants, the women with dysmenorrhea reported significant alleviation of cramps during menstruation after the 12-week TCM treatment. Mixed model analysis revealed that TCM prescriptions were more effective in alleviating fatigue, hot flashes, dizziness, painful breasts, excitement, and irritability in the primary dysmenorrhea group (N=36 than in the endometriosis group (N=34. Conclusion. TCM prescriptions based on syndrome differentiation theory might be a potentially viable choice for treating painful menstruation and premenstrual symptoms after ruling out endometriosis.

  9. C-terminal region of EBNA-2 determines the superior transforming ability of type 1 Epstein-Barr virus by enhanced gene regulation of LMP-1 and CXCR7.

    Full Text Available Type 1 Epstein-Barr virus (EBV strains immortalize B lymphocytes in vitro much more efficiently than type 2 EBV, a difference previously mapped to the EBNA-2 locus. Here we demonstrate that the greater transforming activity of type 1 EBV correlates with a stronger and more rapid induction of the viral oncogene LMP-1 and the cell gene CXCR7 (which are both required for proliferation of EBV-LCLs during infection of primary B cells with recombinant viruses. Surprisingly, although the major sequence differences between type 1 and type 2 EBNA-2 lie in N-terminal parts of the protein, the superior ability of type 1 EBNA-2 to induce proliferation of EBV-infected lymphoblasts is mostly determined by the C-terminus of EBNA-2. Substitution of the C-terminus of type 1 EBNA-2 into the type 2 protein is sufficient to confer a type 1 growth phenotype and type 1 expression levels of LMP-1 and CXCR7 in an EREB2.5 cell growth assay. Within this region, the RG, CR7 and TAD domains are the minimum type 1 sequences required. Sequencing the C-terminus of EBNA-2 from additional EBV isolates showed high sequence identity within type 1 isolates or within type 2 isolates, indicating that the functional differences mapped are typical of EBV type sequences. The results indicate that the C-terminus of EBNA-2 accounts for the greater ability of type 1 EBV to promote B cell proliferation, through mechanisms that include higher induction of genes (LMP-1 and CXCR7 required for proliferation and survival of EBV-LCLs.

    To determine the effect of the menstrual cycle on the optic nerve head topographic analysis of normally menstruating migrainous women. Randomly selected one eye of 44 migrainous and 49 healthy control women with regular menstrual cycles were included in the study. All subjects underwent complete ocular examination. Optic nervehead topographic analysis were performed using a confocal scanning laser ophthalmoscope, HRT II (Heidelberg Retinal Tomograph II, software version 1.6;Heidelberg Engineering, Heidelberg, Germany). They were repeated for two times during the menstrual cycle: in follicular phase (7th to 10th day of the cycle) and in the luteal phase (days 3 to 4 before the menstrual bleeding). Serum estradiol, progesterone, and luteinizing hormone measurements were repeated at each menstrual phase. The mean age of migrainous and control subjects were 31.5 + 5.1 years and 33.4 +/- 3.7 years, respectively (P > 0.05). Their mean disc areas were 2.26 +/- 0.46 mm(2) and 1.95 +/- 0.39 mm(2), respectively(P 0.05). The parameter rim volume decreased, while the parameters cup volume and cup shape measure increased significantly in the luteal phase of the migrainous women (all P values cup parameters during the menstrual cycle of the migrainous women. Further clinical trials on ocular blood flow changes during the menstrual cycle of the migrainous women may highlight the role of sex steroids in the optic nerve head of the migrainous women.

    It has been shown that female workers exposed to ethylene glycol ethers (EGEs) in the semiconductor industry have higher risks of spontaneous abortion, subfertility, and menstrual disturbances, and prolonged waiting time to pregnancy. To examine whether EGEs or other chemicals are associated with long menstrual cycles in female workers in the semiconductor manufacturing industry. Cross-sectional questionnaire survey during the annual health examination at a wafer manufacturing company in Taiwan in 1997. A three tiered exposure-assessment strategy was used to analyse the risk. A short menstrual cycle was defined to be a cycle less than 24 days and a long cycle to be more than 35 days. There were 606 valid questionnaires from 473 workers in fabrication jobs and 133 in non-fabrication areas. Long menstrual cycles were associated with workers in fabrication areas compared to those in non-fabrication areas. Using workers in non-fabrication areas as referents, workers in photolithography and diffusion areas had higher risks for long menstrual cycles. Workers exposed to EGEs and isopropanol, and hydrofluoric acid, isopropanol, and phosphorous compounds also showed increased risks of a long menstrual cycle. Exposure to multiple chemicals, including EGEs in photolithography, might be associated with long menstrual cycles, and may play an important role in a prolonged time to pregnancy in the wafer manufacturing industry; however, the prevalence in the design, possible exposure misclassification, and chance should be considered.

    Oral administration of dydrogesterone during second half of menstrual cycle has been shown to reduce menstrual irregularities. This prospective, observational study aimed to determine continued effectiveness of dydrogesterone (prescribed between 1 and 6 cycles or longer) in menstrual cycle regularization in Indian women aged ≥18 years with irregular menstrual cycle for at least 3 months. Those achieving regular cycles (21 to 35 days, inclusive) during treatment were followed up for 6 months after cessation of dydrogesterone treatment. Of the 910 women completing dydrogesterone treatment, 880 (96.7%) achieved cycle regularization (p<0.0001 for 90% success rate) at end of treatment (EOT). Of the 788 subjects available for follow up at 6 months, 747 (94.8%) reported cycle regularity (p<0.0001 for 90% success rate). At EOT, the mean cycle duration reduced by 16.14 (±24.04) days and mean amount of menstrual bleeding decreased by 0.45 (±1.20) pads/day. While five subjects reported worst pain at baseline, none experienced it at EOT. One serious adverse event (appendicitis) and three non-serious adverse events were reported. Dydrogesterone regularizes and improves the duration of the menstrual cycle, reduces the amount of bleeding, relieves menstrual pain and prevents relapse of irregular cycles at six months after discontinuation of treatment.

    MRI (Magnetic Resonance Imaging) is useful facilitation to perform analysis of tissue structures with the gray scale. By use of super-conducting MRI with 0.5T resistive magnet, present study was designed to analyse characteristic features of the human uterus throughout menstrual cycle. Both T 1 and T 2 values of the endometrium, the junctional zone and the myometrium were estimated on total nine volunteers of nomal healthy women aged from 21 to 30 y.o. during menstrual cycle. MRI was taken in the mid ∼ late proliferative, the secretory, and the menstrual stage. Moreover, relative square ratio of the endometrium and the junctional zone to the corpus uteri were measured by computed image analyser (Lusex 500). Following results were obtained. 1) Both T 1 and T 2 values of the endometrium and the junctional zone were lowest in the menstrual phase. In the myometrium, T 1 values were shown as same tendency comparing with the above two layers but T 2 values were lowest in the proliferative phase and the menstrual one. 2) Proportional values of the endometrium to the corpus uteri increased from 13.8% in the proliferative phase to 17.9% in the secretory phase and decreased to 8.0% in the menstrual phase. While that in the junctional zone decreased from 26.6% to 23.4% in secretory phase and increased to 35.0% in the menstrual phase. (author)

    Menstrual hygiene management remains a taboo in many communities in Nepal. Cultural beliefs about menstruation such as food taboos and untouchability have negative impact on dignity, health and education of adolescent girls. The objective of the study was to assess the current knowledge, attitude and practice of school adolescents on menstrual hygiene management in Doti District in Far-Western Nepal. This cross-sectional study was carried out from October to December 2016 at seven village development committees in Doti district, Nepal. This study was done among 276 students from grade seven and eight of 11 schools. Self-administered structured questionnaire was used to obtain information from school students. Descriptive analysis was done to analyse the knowledge, attitude and practice of school adolescents on menstrual hygiene management. 67.4% respondents had fair knowledge and 26.4% respondents had good knowledge on menstrual hygiene management. However, out of 141 female adolescent respondents, only 56 (40%) were engaged in good menstrual hygiene practices. Around half of the respondents had positive attitude towards menstrual hygiene management related issues. Although knowledge on menstrual hygiene management among school adolescents is fair, still attitude and practice need to improve. Findings indicate the need of behavior change communication campaigns along with frequent reinforcement of school health education programs.

Members of the Practitioner Research and Collaboration Initiative practice-based research network identifying as Western Herbalists (WHs) completed a specifically developed, online questionnaire. Western Herbalists regularly treat menstrual problems, perceiving high, though differential, levels of effectiveness. For menstrual problems, WHs predominantly prescribe individualised formulas including core herbs, such as Vitex agnus-castus, and problem-specific herbs. Estimated clients' weekly cost (median = $25.00) and treatment duration (median = 4-6 months) covering this Western herbal medicine treatment appears relatively low. Urban-based women are more likely than those rurally based to have used conventional treatment for their menstrual problems before consulting WHs (p = .001). Only 19% of WHs indicated direct contact by conventional medical practitioners regarding treatment of clients' menstrual problems despite 42% indicating clients' conventional practitioners recommended consultation with WH. Western herbal medicine may be a substantially prevalent, cost-effective treatment option amongst women with menstrual problems. A detailed examination of the behaviour of women with menstrual problems who seek and use Western herbal medicine warrants attention to ensure this healthcare option is safe, effective, and appropriately co-ordinated within women's wider healthcare use.

    From a psychological perspective, the menstrual cycle has been a research topic for more than 50 years. The most recent menstrual cycle research has been driven by an increased interest in sex differences in neuroscience, and the urge to understand sex disparities in prevalence, clinical presentation, and treatment response in psychiatric or neurologic disorders. Indeed, the menstrual cycle is an excellent model of ovarian steroid influence on emotion, behavior, and cognition. This review summarizes the emotion-related and cognitive findings of methodologically sound menstrual cycle studies. In particular, the review is devoted to the sex hormone-induced emotional disturbances in women with premenstrual dysphoric disorder, a subgroup of women responding with enhanced sensitivity to the normal fluctuations in endogenous hormone levels during the menstrual cycle. In addition, emotion processing and cognitive findings across the menstrual cycle in healthy women are also discussed. The overall conclusion is that that menstrual cycle differences in sexually dimorphic cognitive tasks are small and difficult to replicate. Emotion-related changes are more consistently found and are better associated with progesterone and the luteal phase, than with estradiol. © 2018 Elsevier Inc. All rights reserved.

    Abnormal Uterine Bleeding (AUB) is a frequent cause of visits to the emergency department and a major reason for concern among adolescents and their families. The most common cause of AUB, in otherwise healthy adolescents, is ovulatory dysfunction, although 5-36% of adolescents who present with heavy menstrual bleeding, have an underlying bleeding disorder (BD). The most common form of BDs is von Willebrand Disease, reflecting 13% of adolescents with AUB. Management of AUB depends on the underlying etiology, the bleeding severity, as well as the need for hospitalization. Treatment of adolescents with an underlying coagulopathy depends on the severity of the BD, while therapeutic interventions are summarized in supportive measures, hormonal treatments (e.g. Combined Oral Contraceptives), non-hormonal treatments (e.g. tranexamic acid and desmopressin), surgical options (e.g. dilatation & curettage) and treatment options in specific conditions.

    Female respondents were given the opportunity to choose feature films for viewing. Choices were made on the basis of synopses and promotional videos. These materials projected (i) a focus on erotic, sexual events, (ii) romantic themes, (iii) action-packed violent drama, and (iv) hilarious comedy. Additionally, respondents evaluated the appeal of the projected films. Respondents' position in the menstrual cycle was then determined, with placement into one of seven 4-day phases. Measured in both choices and evaluations, a postmenstrual surge in erotic interest was evident. Erotic interest was also pronounced prior to and during menses. In contrast, it was at a minimum during the first half of the luteal phase. The choice of romantic films was not appreciably influenced by cycle position. However, in evaluating films with romantic themes, premenstrual women expressed particularly little interest in this genre.

    A major difficulty in building Bayesian network (BN) models is the size of conditional probability tables, which grow exponentially in the number of parents. One way of dealing with this problem is through parametric conditional probability distributions that usually require only a number of parameters that is linear in the number of parents. In this paper, we introduce a new class of parametric models, the Probabilistic Independence of Causal Influences (PICI) models, that aim at lowering the number of parameters required to specify local probability distributions, but are still capable of efficiently modeling a variety of interactions. A subset of PICI models is decomposable and this leads to significantly faster inference as compared to models that cannot be decomposed. We present an application of the proposed method to learning dynamic BNs for modeling a woman's menstrual cycle. We show that PICI models are especially useful for parameter learning from small data sets and lead to higher parameter accuracy than when learning CPTs.

    The aim of this study was to determine the nature of incidental ovarian 18 F-fluoro-2-deoxyglucose (FDG) accumulation on positron emission tomography (PET) and the correlation with the menstrual cycle and menopause. We identified 19 incidental FDG accumulations in the ovary (FAOs). FDG PET images were compared with other anatomical imaging methods [magnetic resonance imaging (MRI), computed tomography (CT) or ultrasonography (US)]. Pathological findings, FDG PET scan during the next menstrual cycle and follow-up images (PET, CT and MRI) were reviewed. To establish the relation of FAOs to the menstrual cycle, we reviewed whole-body FDG PET acquired from 207 consecutive women and the pre-examination questionnaires, including data regarding the menstrual cycle. All spherical or discoid FAOs were attributed to normally developing ovarian follicles and corpora lutea on the basis of concurrent MRI, US or the follow-up PET scan. Three of the FAOs were proved pathologically to be either normal ovaries or a haemorrhagic corpus luteum. Fifteen FAOs spontaneously disappeared on the short-term follow-up PET scans. Of 207 women, 61 had active menstrual cycles. FAOs were found in 12 out of 61 premenopausal women (20%), appearing between the 10th and 25th days of the menstrual cycle. No FAOs were found in the women who did not have a menstrual cycle. Physiological ovarian FDG accumulation could be found around the time of ovulation and during the early luteal phase of the menstrual cycle in premenopausal woman. Since FAO is dependent on the menstrual cycle, it can be avoided by scheduling PET just after menstruation. (orig.)

  2. Menstrual cycle influence on cognitive function and emotion processing - from the reproductive perspective

    Full Text Available The menstrual cycle has attracted research interest ever since the 1930s. For many researchers the menstrual cycle is an excellent model of ovarian steroid influence on emotion, behavior, and cognition. Over the past years methodological improvements in menstrual cycle studies have been noted, and this review summarizes the findings of methodologically sound menstrual cycle studies in healthy women. Whereas the predominant hypotheses of the cognitive field state that sexually dimorphic cognitive skills that favor men are improved during menstrual cycle phases with low estrogen and that cognitive skills that favor women are improved during cycle phases with increased estrogen and/or progesterone, this review has not found sufficient evidence to support any of these hypotheses. Mental rotation has gained specific interest in this aspect, but a meta-analysis yielded a standardized mean difference in error rate of 1.61 (95% CI -0.35 – 3.57, suggesting, at present, no favor of an early follicular phase improvement in mental rotation performance. Besides the sexually dimorphic cognitive skills, studies exploring menstrual cycle effects on tasks that probe prefrontal cortex function, for instance verbal or spatial working memory, have also been reviewed. While studies thus far are few, results at hand suggest improved performance at times of high estradiol levels. Menstrual cycle studies on emotional processing, on the other hand, tap into the emotional disorders of the luteal phase, and may be of relevance for women with premenstrual disorders. Although evidence at present is limited, it is suggested that emotion recognition, consolidation of emotional memories, and fear extinction is modulated by the menstrual cycle in women. With the use of functional magnetic resonance imaging, several studies report changes in brain reactivity across the menstrual cycle, most notably increased amygdala reactivity in the luteal phase.

    Objectives: To assess the apparent diffusion coefficient (ADC) changes of the normal uterine zones among reproductive women during the menstrual cycle. Methods: The study included 101 women of reproductive age, each with regular cycle and normal endometrium/myometrium, as proved on histopathology or MR imaging examination. Diffusion-weighted (DW) imaging was performed along the axial plane, using a single shot, multi-slice spin-echo planar diffusion pulse sequence and b-values of 0 and 800 s/mm{sup 2}. The mean and standard deviation of the ADC values of normal endometrium/myometrium were calculated for menstrual, proliferative and secretory phase. Analysis of variance followed by the least significant difference test was used for statistical analysis. Results: The ADC values of the endometrium were different in the three phases of the menstrual cycle (menstrual phase: 1.25 {+-} 0.27; proliferative phase: 1.39 {+-} 0.20; secretory phase: 1.50 {+-} 0.18) (F: 9.64, p: 0.00). Statistical significant difference was observed among all groups (p < 0.05). The ADC values of the normal myometrium were different in the three phases of the menstrual cycle (menstrual phase: 1.91 {+-} 0.35; proliferative phase: 1.72 {+-} 0.27; secretory phase: 1.87 {+-} 0.28) (F: 3.60, p: 0.03). Statistical significant difference was observed between menstrual and proliferative phase and between proliferative and secretory phase (p < 0.05). No significant difference was noted between menstrual and secretory phase (p > 0.05). Conclusions: A wide variation of ADC values of normal endometrium and myometrium is observed during different phases of the menstrual cycle.

    Menarche is an independent puberty event in a girl's life, and is associated with physical growth, ability in marriage and fertility. Therefore, poor menstrual health can be a major determinant of morbidity, as well as physical, mental and social problems in this age group. The aim of this study was to explore the effective factors on menstrual health among female students in Bam city. The qualitative study was conducted using content analysis approach in 2017. The participants were 32 individuals consisting of 13 students, 10 mothers of the same students, 9 school associates and health educators of 5 secondary schools in Bam city, who were selected based on an objective-oriented approach. The sampling was done until data saturation. Data collection methods were semi-structured and in-depth interview. Data analysis was performed using the steps suggested by Graneheim and Landman. There were two categories (easy interaction and inappropriate adaptation to changes in health behavior), 13 sub-categories and 52 initial codes. The positive factors included easy access to sanitary pads, appropriate school education, easy access to health and therapeutic services and school flexibility on menstrual issues, while the negative factors included inadequate facilities for sanitary pad disposal, lack of access to informed people about menstrual issues, insufficient attention to menstrual problems, feeling ashamed, the high cost of menstrual health, self-medication with traditional medicines, inadequate self-directed education, lack of awareness and trust in health center staff, and following family and teachers in menstrual problems. Overall, this study indicated that economic, social, cultural and educational factors affect menstrual health. Therefore, the identification of each of these factors helps planners to apply the most appropriate methods and strategies for menstrual health improvement.

    Menstrual cycle is an integral part of life of women. There is widespread agreement that changes in the levels of oestrogen and progesterone associated with menstrual cycle also affect different systems of the body besides reproductive system. Levels of oestrogen and progesterone are maximum in the secretory phase and minimum just before the menstruation .Bronchial asthma is one of the commonest chronic respiratory diseases. Premenstrual worsening of asthma symptoms has been reported to affect 33-40% of asthmatic women. This exacerbation of asthma symptoms has been correlated with the oestrogen and progesterone levels. The association between menstrual cycle and lung functions in normal females has also been recognised. The pathophysiology of this process is still not proved. The purpose of our study was to confirm the probable effects of the female hormones on lung functions in normal and asthmatic women in different phases of menstrual cycle and to compare them. Methods: The study was done on 40 normal and 40 asthmatic females in the age group of 15-45 years. Pulmonary function tests were done in three phases of menstrual cycle i.e. follicular, secretory and menstrual in all the subjects. Results: The mean value of lung functions, i.e., FVC, FEV, PEFR, FEF25-75%, FEF 200-1200 were significantly lower in asthmatic females than normal ones (p<0.01) in all three phases. The lung functions of both asthmatic and non-asthmatic females in secretory phase were significantly higher than in menstrual phase (p<0.005). The PFTs in menstrual phase were even lower than the follicular phase (p<0.04). Conclusion: Respiratory parameters of both asthmatic and non-asthmatic women in reproductive age group show significant variation in different phases of menstrual cycle. The smooth muscle relaxant effect of progesterone and probably oestrogen might have contributed to it. The lung function parameters in asthmatics were of lower value compared to normal women.

    Full Text Available Background: The issue of menstrual hygiene is inadequately acknowledged in our nation. The use of sanitary pads and washing the genital area are essential practices for good menstrual hygiene. Poor menstrual hygiene may lead to itching or rashes in the perineal region, bad odor, and sometimes, major complications such as pelvic inflammatory disease and toxic shock syndrome. Therefore, the objective of this study was to assess the knowledge and practice of menstrual hygiene among reproductive age group women. Methods: A Community-based cross-sectional study design was employed. Study was conducted from January 2012 to April 2013. Data were collected using a pretested semi-structured structured questionnaire. The data were entered and analyzed into a computer using SPSS version 20. Results: In this study, 584 (81.7% respondents had good practice of menstrual hygiene. The findings of the study showed a significant positive association between good practices of menstrual hygiene and years of education of the study subject (adjusted odds ratio [AOR] =9.3, 95% confidence interval [CI]: 4.4–19.5, having a higher socioeconomic status (AOR = 9.27, 95% CI: 4.7–18.03. Conclusions: Awareness of good menstrual practices is of utmost importance. Health education regarding menstrual hygiene should be a part of school curriculum and health institutes. Social marketing of good quality, low-cost sanitary napkins at accessible outlets, provision for adequate water supply, vending machines for low-cost sanitary napkins, privacy and wall-mounted incinerators for disposal in schools, workplaces, and public places would go a long way in improving the menstrual hygiene and help them in securing healthy lifestyle.

    Full Text Available Background: Socio-cultural factors have a bearing on women's attitude towards menstruation. Health care providers should be aware of how women react to menstruation while providing health care. Aims & Objectives: To elicit menstrual awareness and knowledge of the rural adolescent girls and assess how this awareness, knowledge and demographics influence their menstrual attitude. Methodology: A community based descriptive cross-sectional study was undertaken among 245 adolescent school going girls in a rural area. Adolescent Menstrual Attitude Questionnaire (AMAQ was used as a data collection device. Data were compared by using SPSS (ver. 20.0 at the level of 0.05. Results: At menarche, 59.9% adolescents were aware of menstruation and in 3/4th of them, mothers were the source of information. There was a statistically significant effect of menstrual awareness (yes or no and menstrual knowledge (nil, partial and complete on the combined dependent variables (F(6,238=9.0, p= 0.000, Wilk’s Lambda=0.81, partial eta square=0.29 and F(6,237=8.01, p= 0.000, Wilk’s Lambda=0.69, partial eta square=0.20  respectively. Older adolescents had favorable attitude towards menstruation in three significant dimensions i.e. living with menarche, openness and acceptance. Significant effect of mother’s educational level was observed on five dimensions of menstrual attitude. Conclusion: Menstrual attitude is significantly affected by menstrual awareness and knowledge.  Demographics too contributed in bringing positive attitude. There is a need to plan menstrual health education programme for adolescent girls and their mothers.

Tongue surface photographs were taken in the follicular phase and the luteal phase of thirty-two volunteers with biphasic basal body temperature. Color values on five areas of the tongue surface were examined and comparisons of color values were made between the two phases according to the red–green–blue (RGB, hue–saturation–brightness (HSB, luminance-a-b (Lab, and cyan–magenta–yellow–black (CMYK models. Based on the RGB model, the values of green and blue in the tip area were larger in the follicular phase than both in the luteal phase. The values of magenta and yellow based in the CMYK model were smaller in the tip area in the follicular phase than that in the luteal phase. The saturation in the tip area was smaller in the follicular phase than that in the luteal phase. Based on the Lab model, b value in the middle area was smaller in the follicular phase than that in the luteal phase. The data revealed that tongue color varied within a eumenorrheic menstrual cycle, suggesting that tongue color differences between the follicular and luteal phases need to be considered while practicing tongue diagnosis (舌診 shé zhěn or performing clinical studies among childbearing women.

    We have tried fundamental studies, reference values and relationship to menstrual cycle on Prolactin RIA BEAD II kit which has a method of IRMA using monocronal antibody. On clinical studies, we investigated change of serum prolactin level during the menstrual cycle and relationship to other hormones (LH, FSH, estradiol, progesterone). It was the result that prolactin level of follicular phase was lower than that of preavulatory phase and luteal phase. We conclude that change of prolactin level during the menstrual cycle is related with change of estradiol level. (author)

    2014-01-01

    We extend objectification theory research to consider the relationship between self-objectification and attitudes toward an alternative menstrual product in a diverse sample of female undergraduates from the United States (N = 151). We use a survey design to investigate attitudes toward one's menstruation as a potential mechanism that may explain this relationship. Reactions to an alternative menstrual product were predominantly negative, supporting prior research on stigma and shame surrounding menstruation. Exploratory structural equation modeling revealed attitudes toward one's menstruation mediated the relationship between self-objectification and participants' reactions to an alternative menstrual product. Implications for women's health are discussed.

    This cross-sectional study aimed to investigate the association between menstrual cycle lenght and metabolic parameters in non-hyperandrogenic women with polycystic ovarian morphology, n = 250. Metabolic profiles of all participants were evaluated using anthropometric parameters (body mass index, waist circumference), parameters of dyslipidemia (total cholesterol, HDL-cholesterol, triglycerides) and markers of insulin resistance (fasting insulin, homeostasis model assessment for insulin resistance index). The associations between menstrual cycle lenght and cardiometabolic risk factors such as insulin resistance, dyslipidemia, and obesity were investigated. In non-hyperandrogenic women with polycystic ovarian morphology, menstrual cycle lenght was associated with hypertriglyceridemia and insulin resistance independently of body mass index. Moreover, menstrual cycle lenght added value to body mass index in predicting hypertriglyceridemia. The optimal menstrual cycle lenght cut-off value for identifying of non-hyperandrogenic women with polycystic ovarian morphology at metabolic risk was found to be 45 days. Metabolic profile of non-hyperandrogenic women with polycystic ovarian morphology (n = 75) with menstrual cycle lenght >45 days was similar to that of hyperandrogenic women with polycystic ovarian morphology (n = 138) while metabolic profile of non-hyperandrogenic women with polycystic ovarian morphology with menstrual cycle lenght ≤45 days (n = 112) was similar to that of controls (n = 167). Non-hyperandrogenic women with polycystic ovarian morphology with menstrual cycle lenght >45 days had higher prevalence of cardiometabolic risk factors compared to those with menstrual cycle lenght ≤45 days.

    Adolescence in girls has been recognized as a special period marked with the onset of menarche. Even though menstruation is a natural process, it is associated with misconceptions, malpractices and challenges among girls in developing countries. However, much is not documented; school-absenteeism and dropout are a common problem among girls in rural Ethiopia. Focusing among school girls, this study has examined knowledge about menstruation, determinants of menstrual management and its influence on school-attendance in Northeast Ethiopia. We conducted a mixed-method research combining quantitative and qualitative methods in Northeast Ethiopia. The quantitative study was conducted among 595 randomly selected adolescent school girls. Nine in-depth interviews; five school-dropout girls and four female teachers, and four focus group discussions among school girls were conducted in 2013. The mean age at menarche was 13.98 (±1.17) years. About 51% of girls had knowledge about menstruation and its management. Only a third of the girls used sanitary napkins as menstrual absorbent during their last menstruation. Girls from urban areas, had mothers of secondary and above education and, families of higher monthly expenditure had more chance of using sanitary napkins than their counterparts. More than half of the girls reported to have been absent from school during their menstruation period. Those who did not use sanitary napkins were more likely to be absent from school [AOR-95% C.I: 5.37 (3.02 - 9.55)]. Fifty eight percent of girls reported that their school-performance had declined after they had menarche. In addition, the qualitative study indicated that school-dropout was common among girls who experienced teasing and humiliation by classmates when their clothes were stained with blood as they do not use sanitary napkins. Though there is an effort to increase girls' school enrollment, lack of basic needs, like sanitary napkins that facilitate routine activates of girls

    To make comparisons between acupuncture and acupressure for preventing menstrual migraine (MM). MM is one kind of migraine associated with females' menses. It is often associated with increased menstrual distress and disability, leading to decreased daily activity and quality of life. A randomized and controlled pilot study with three groups: verum acupuncture (VA) group, acupressure (AP) group, and control acupuncture (CA) group. The study lasted for seven cycle-months, with a 1-cycle-month baseline observation (T1), a 3-cycle-month intervention (three times per cycle-month) (T2-T4), and a 3-cycle-month follow-up (T5-T7). Outcome measures were number of migraine days, average and peak pain, total duration period of MM, and percentage of patients with ≥ 50% reduction in the number of MM days. A total of 18 participants were included in the analysis (VA, n = 7; AP, n = 6; CA, n = 5). Both VA and AP were significantly more effective than CA for reducing MM days during the intervention period. Both VA and AP tended to be more effective than CA for reducing peak pain during the intervention period. No significant differences for the outcomes were observed among VA, AP, and CA during the follow-up period. No serious adverse events were reported. Results of the pilot study suggest that both VA and AP could be considered as alternative and safe prophylactic interventions for MM. Register ClinicalTrials.gov Identifier: NCT02592681.

    Full Text Available Abstract Background Tubal sterilization is the method of family planning most commonly used. The existence of the post-tubal-ligation syndrome of menstrual abnormalities has been the subject of debate for decades. Methods In a cross-sectional study, 112 women with the history of Pomeroy type of tubal ligation achieved by minilaparatomy as the case group and 288 women with no previous tubal ligation as the control group were assessed for menstrual abnormalities. Results Menstrual abnormalities were not significantly different between the case and control groups (p = 0.824. The abnormal uterine bleeding frequency differences in two different age groups (30–39 and 40–45 years old were statistically significant (p = 0.0176. Conclusion Tubal sterilization does not cause menstrual irregularities.

    Menstrual status, both past and current, has been established as an important determinant of bone mineral density (BMD) in young exercising women. However, little is known regarding the association between the cumulative effect of menstrual status and indices of bone health beyond BMD, such as bone geometry and estimated bone strength. This study explores the association between cumulative menstrual status and indices of bone health assessed using dual-energy x-ray absorptiometry (DXA), including femoral neck geometry and strength and areal BMD (aBMD), in exercising women. 101 exercising women (22.0±0.4years, BMI 21.0±0.2kg/m(2), 520±40min/week of self-reported exercise) participated in this cross-sectional study. Women were divided into three groups as follows based on their self-reported current and past menstrual status: 1) current and past regular menstrual cycles (C+P-R) (n=23), 2) current and past irregular menstrual cycles (C+P-IR) (n=56), 3) and current or past irregular cycles (C/P-RIR) (n=22). Current menstrual status was confirmed using daily urinary metabolites of reproductive hormones. DXA was used to assess estimates of femoral neck geometry and strength from hip strength analysis (HSA), aBMD, and body composition. Cross-sectional moment of inertia (CSMI), cross-sectional area (CSA), strength index (SI), diameter, and section modulus (Z) were calculated at the femoral neck. Low CSMI, CSA, SI, diameter, and Z were operationally defined as values below the median. Areal BMD (g/cm(2)) and Z-scores were determined at the lumbar spine, femoral neck, and total hip. Low BMD was defined as a Z-score0.05). However, after controlling for confounding variables, cumulative menstrual status was not a significant predictor of low aBMD. In exercising women, the cumulative effect of current and past menstrual irregularity appears to be an important predictor of lower estimates of femoral neck geometry, as observed by smaller CSMI and CSA, which may serve as an

    In the rural areas of India, women generally use a piece of old cloth as a menstrual device. The aim of this study was to detect human papilloma virus (HPV) from menstrual blood on the menstrual pad and assess whether this could be a useful screening tool for cervical cancer. In Jamkhed area of rural Maharashtra, (population A), we collected menstrual pads from women who provided consent in the 30-50 year age group. The women who had provided menstrual pads underwent HC2 testing. We standardized the method for extracting DNA by PCR from the menstrual pad. The women who tested HPV positive, on the basis of HC2/PCR testing, underwent colposcopy. In the rural population of Pune area of Maharashtra state (population B), menstrual pads were collected. HPV was tested using the PCR method. HPV-positive women and a few HPV-negative women, selected randomly, underwent colposcopy and HC2 testing. In population A, 164 women provided their used menstrual pads and also underwent an HC2 screening test. Of these, six (3.2%) cases were reported as HPV positive. In population B, 365 women provided their used menstrual pads for HPV testing, of which 18 (4.9%) cases were diagnosed as HPV positive. The women who tested HPV positive, on the basis of PCR testing, and 10% randomly selected HPV-negative cases (37) and 18 women who voluntary requested testing underwent colposcopy and HC2 testing. The sensitivity of menstrual pad HPV testing compared with gold standard HC2 testing was 83% [95% confidence interval (CI): 0.47-0.97], 67% (95% CI: 0.30-0.91) and specificity was 99% (95% CI: 0.96-0.99), 88% (95% CI: 0.77-0.94) in population A and population B, respectively. The sensitivity of diagnosing CIN lesion was 83% (95% CI: 0.44-0.97) and specificity was 95% (95% CI: 0.91-0.97). On the basis of the sensitivity and specificity results, and the completely noninvasive, simple and convenient method of detecting HPV, menstrual pad might be considered a cervical cancer screening tool in rural

    A long-term N balance study was carried out to determine the adequacy of an estimated protein requirement level recommended for young healthy Nigerian women and the effect of the menstrual cycle on the requirement. Eleven healthy young women, 25 (SD 2.6) years, were fed on a diet providing 0.6 g protein (N x 6.25)/kg per d and an average energy intake of 0.17 (SD 0.012) MJ/kg per d. Urine, faeces, sweat and menstrual fluids were collected for estimation of N balance. Menstrual N loss varied among individuals ranging from 46 to 124 mg N/d with an average of 89 (SD 21.8) mg N/d. Individual N balance was found to vary according to the day of the menstrual cycle. Positive N balances were recorded at about ovulation while negative balances were observed just before the onset of menstruation. The average N balance ranged from +8.49 (SD 5.64) to -430 (SD 7.84) mg N/kg per d. Nevertheless, an overall cumulative positive N balance of +5.7 (SD 6.98) mg N/kg per d which did not change significantly with time was observed for the last 5 d of two consecutive 20 d diet periods, although three subjects were in negative N balance. Blood biochemical measurements were stable except for one subject who had elevated serum aspartate aminotransferase (EC 2.6.1.1) levels. These findings suggest that our estimate of protein requirements was sufficient to achieve N balance equilibrium in a majority (70%) of young women. However, to satisfy 97.5% of the population, slight adjustments might be necessary in the energy intake since subjects who were in cumulative negative N balance also lost weight.

Prospective clinical study. University hospital. Thirteen women with apparently normal menstrual cycle (group 1); 18 women undergoing IVF-ET (group 2); and 14 low-risk pregnant women (group 3). We assayed plasma and urine concentrations of TGF-beta1, urine content, and distribution of GAG. Blood and urine samples were collected during days 2 to 3, 12 to 13, and 23 to 24 in group 1; in group 2, samples were obtained at menstrual phase, oocyte pick-up day, and 15 days after ET; in group 3, samples were obtained during gestational weeks 10-12, 22-24, and 30-32 and 1 month after delivery. Changes in TGF-beta1 and GAG content. The mean value of total urinary trypsin inhibitor/chondroitin sulfate (UTI/CS) showed a distinct peak at day 12 of the menstrual cycle in the fertile women in whom we monitored the ovulatory period. In the IVF-ET group, GAG distribution and TGF-beta1 levels showed significant differences during the cycle. We observed increased levels of plasma TGF-beta1 15 days after ET. A significant increase of total UTI/CS value with increasing gestation was detected. Transforming growth factor beta1 and GAG levels could represent an additional tool to monitor reproductive events and could be useful, noninvasive markers of ovulation and ongoing pregnancy.

    Full Text Available Abstract Background Sex hormones may play an important role in observed gender differences in asthma incidence and severity, as well as in the observed changes in asthma symptoms during times of hormonal fluctuation (i.e.; premenstrual, pregnancy, etc.. This pilot study sought to demonstrate the feasibility of data collection methods to investigate the effects of sex hormones on lung function in women. Findings A cohort of 13 women (6 with and 7 without prior asthma diagnoses who were having menstrual periods and were not taking hormones collected urine samples daily for measurement of estrogen (estrone E1C and progesterone (Pregnanediol-glucuronide PDG metabolites over the course of a menstrual segment (bleeding episode plus the following bleeding-free interval. Hormones were used to estimate menstrual segment phase (follicular versus luteal based on a published algorithm. Daily bleeding and FEV1 measurements were recorded and percent predicted FEV1 was calculated. Percent predicted FEV1 decreased over the course of the follicular but not the luteal phase. More specifically, among women without a prior asthma diagnosis, the E1C/PDG ratio and E1C and PDG were individually associated with FEV1 in the follicular phase. No associations were found between hormones and percent predicted FEV1 in the luteal phase or among asthmatic women. E1C was associated with FEV1 in the five days before bleeding onset only among non-asthmatic women. Discussion A study of contiguous daily hormones and symptoms over menstrual segments from a large group of women with and without asthma is needed to better determine within-woman cyclicity of the observed patterns.

    Full Text Available Introduction & Objective: Most women in the course of their lives will experience menstrual bleeding. Some have bleeding almost all the time. Different approaches have been proposed and drugs with fewer side effects are preferred. The aim of this study was to compare the ef-fects of herbal medicines (fennelin & vitagnus and mefenamic acid in the treatment of severity of menstrual bleeding. Materials & Methods: This double blind clinical trial was carried out in one hundred and five students with severe menstrual bleeding at Hamadan University of medical sciences in 2010. The students were randomly grouped in four groups and herbal medicines of fennelin & vitagnus, mefenamic acid and placebo. The severity of menstrual bleeding was detected by the Higham table during one cycle before and two cycles after the intervention. The data analyzed by SPSS/16 and P<0.05 was considered significant. Results: Demographic characteristics of the students were similar in the four groups. There was not a significant difference in the mean of severity of menstrual bleeding during the one cycle before intervention between the four groups, but the difference was significant dur-ing the two cycles after the intervention. Mefenamic acid reduces menstrual bleeding com-pared with vitagnus & fennelin and showed no statistically significant difference. Conclusion: All three drugs; mefenamic acid, fennelin and vitagnus have been effective in reducing menstrual bleeding. The two herbal medicines (vitagnus and fennelin can be used as effective and safe drugs to reduce menstrual bleeding. (Sci J Hamadan Univ Med Sci 2014; 21(3:171-176

    Using a specific and sensitive radioimmunoassay, the authors determined levels of inhibinlike material in the urine of eight healthy women with normal menstrual cycle length of 28 +- 4 days. The results revealed a cyclic variation in urinary immunoreactive inhibin levels during the menstrual cycles, with a sharp rise in levels three to four days prior to luteinizing hormone (LH) and follicle-stimulating hormone (FSH) peaks. These levels of immunoreactive inhibin may thus serve as a parameter to detect impending LH surge. (author)

    The aim of the study was to assess the distribution of positive tilt testing (TT) throughout the menstrual cycle and to determine if the phase of menstrual cycle contributes to the duration of the loss of consciousness. TT results of 183 premenopausal women, aged 29.5 ± 9.8 years, were studied. The menstrual cycle was divided into four phases based on the first day of the last menstrual bleeding: perimenstrual (M), preovulatory (F), periovulatory (O) and postovulatory (L). Positive TT results were equally distributed. In patients with TT in O phase, the highest percentage of NTG provocation was needed. Patients in L phase had significantly lower incidence of cardioinhibitory reaction. The longest duration of loss of consciousness was in the M phase. Multiple regression analysis revealed that the duration of loss of consciousness during positive TT was significantly associated with higher number of syncopal events, TT performed in M phase and lower heart rate at TT termination. Cardiodepressive type of neurocardiogenic reaction was more frequent during M and O phase than during L phase. The distribution of positive TT results as well as syncope and presyncope does not differ throughout the menstrual cycle. Diagnostic TT in premenopausal women with unexplained syncope could be performed irrespective of the phase of menstrual cycle. TT has similar sensitivity throughout the menstrual cycle. During the postovulatory phase, cardioinhibitory reaction is less frequent than in M and O phases. The duration of loss of consciousness is longer during the M phase of the menstrual cycle independently of the higher syncope number and lower heart rate at TT termination.

    To determine the effect of the menstrual cycle on optic nerve head topographic analysis in normally menstruating, healthy women. The study included single eyes selected randomly from each of 52 healthy women with regular menstrual cycles. All subjects underwent a complete ocular examination. Optic nerve head topographic analyses were performed using a confocal scanning laser ophthalmoscope, the Heidelberg Retinal Tomograph II (HRT II, software version 1.6). The analyses were repeated three times during the menstrual cycle: in the follicular phase (days 7-10 of the cycle), at ovulation, and in the late luteal phase (days 1-3 before menstrual bleeding). Serum oestradiol, progesterone and luteinizing hormone levels were measured at each menstrual phase. Fourteen subjects were excluded from the study. The mean age of the subjects (n = 38) was 25.6 +/- 3.7 years (range 21-34 years). Blood oestradiol levels were significantly lower in the late luteal phase (35.8 pg/ml) (p cup : disc ratio, cup : disc area ratio and the cup area were significantly higher during the luteal phase (p menstrual cycle in healthy women significantly alter neuroretinal rim area and cup variables of the optic nerve head.

    Research in the past decade has revealed average to poor menstrual health among many Iranian girls. The present study investigated the effectiveness of a health promotion project on improving menstrual health in adolescent girls in Iran. A quasi-experimental study was conducted to evaluate the effectiveness of the health intervention program. A total of 698 students (study participants and controls) in several schools in Mazandaran province, Iran were included. The project comprised 10 two-hour educational sessions. Educational topics included the significance of adolescence, physical and emotional changes during adolescence, pubertal and menstruation health and premenstrual syndrome. A self-administered questionnaire measuring demographic characteristics, behaviors during menstruation, menstrual patterns, sources of information about menstruation and personal health data was administered. The questionnaire was administered to all participating students after the experimental group received the training. Among the most significant results was the impact of educational sessions on bathing and genital hygiene. A total of 61.6% in the experimental group compared with 49.3% in the control group engaged in usual bathing during menstruation (p = 0.002). Individual health status was significantly statistically correlated with menstrual health. Attitude towards menstruation was also significantly related to menstrual health. The present study confirms that educational interventions, such as the health promotion project in this study, can be quite effective in promoting menstrual health.

    The human endometrium is a highly dynamic tissue with the ability to cyclically regenerate during the reproductive life. Endometrial mesenchymal stem-like cells (eMSCs) located throughout the endometrium have shown to functionally contribute to endometrial regeneration. In this study we examine whether the menstrual cycle stage and the location in the endometrial bilayer (superficial and deep portions of the endometrium) has an effect on stem cell activities of eMSCs (CD140b"+CD146"+ cells). Here we show the percentage and clonogenic ability of eMSCs were constant in the various stages of the menstrual cycle (menstrual, proliferative and secretory). However, eMSCs from the menstrual endometrium underwent significantly more rounds of self-renewal and enabled a greater total cell output than those from the secretory phase. Significantly more eMSCs were detected in the deeper portion of the endometrium compared to the superficial layer but their clonogenic and self-renewal activities remained similar. Our findings suggest that eMSCs are activated in the menstrual phase for the cyclical regeneration of the endometrium. - Highlights: • The percentages of endometrial mesenchymal-like stem cells (eMSCs) were constant across the menstrual cycle. • Menstruation eMSCs display superior self-renewal and long-term proliferative activities. • More eMSCs reside in the deeper portion of the endometrium than the superficial layer.

    To explore the effects of menstrual cycle on orthodontic pain following initial archwire engagement. Female participants with regular menstrual cycles were recruited and assigned into follicular group or luteal group. Demographical and baseline variables were collected: age, education, menstrual duration, anxiety, oral health impact profile-14 (OHIP-14), and index of complexity outcome and need (ICON). Following initial archwire engagement, orthodontic pain was determined through visual analogue scale (VAS) on 1st day, 2nd day, and 3rd day. Demographical and baseline variables were compared between the two groups. Two-way repeated-measures anova was used to examine the effects of menstrual phase, time, and their interactions on orthodontic pain. Multivariate linear regression was employed to examine the independent effect of each variable on orthodontic pain. Finally, 37 and 39 were assigned to the follicular and luteal groups, respectively, with balanced demographical and baseline data. Orthodontic pain was significantly affected by menstrual phase and time (both P  0.05). Moreover, orthodontic pain was independently predicted by menstrual phase, OHIP, education level, and anxiety (all P < 0.05). We suggest that practitioners arrange female patients to receive initial archwire engagement during their follicular phases to relieve orthodontic pain. © 2016 John Wiley & Sons A/S.

    Epidemiological findings suggest that men and women vary in their pattern of cocaine use resulting in differences in cocaine dependence and relapse rates. Preclinical laboratory studies have demonstrated that female rodents are indeed more sensitive to cocaine's reinforcing effects than males, with estrous cycle stage as a key determinant of this effect. The current study sought to extend these findings to normally cycling female rhesus macaques, a species that shares a nearly identical menstrual cycle to humans. Dose-dependent intravenous cocaine self-administration (0.0125, 0.0250, and 0.0500 mg/kg/infusion) using a progressive-ratio schedule of reinforcement was determined across the menstrual cycle. The menstrual cycle was divided into 5 discrete phases - menses, follicular, periovulatory, luteal, and late luteal phases - verified by the onset of menses and plasma levels of estradiol and progesterone. Dependent variables including number of infusions self-administered per session, progressive ratio breakpoint, and cocaine intake were analyzed according to cocaine dose and menstrual cycle phase. Analysis of plasma hormone levels verified phase-dependent fluctuations of estradiol and progesterone, with estrogen levels peaking during the periovulatory phase, and progesterone peaking during the luteal phase. Progressive ratio breakpoint, infusions self-administered, and cocaine intake did not consistently vary based on menstrual cycle phase. These findings demonstrate that under the current experimental parameters, the reinforcing effects of cocaine did not vary across the menstrual cycle in a systematic fashion in normally cycling rhesus macaques.

    Eating disorders are an important factor in menstrual cycle disorders in girls. Moreover, low self-esteem among adolescent girls may be a risk factor for eating disorders. The aim of the study was to assess the menstrual cycle, eating habits and self-esteem of Polish adolescents. The study was conducted from January 2014 to March 2015 and included 623 girls, aged 15-19, from randomly selected junior high schools in Silesia, Poland, in which their menstrual cycle, risk of eating disorders and self-esteem were evaluated. A five-part questionnaire was used to assess basic demographic data, lifestyle and physical activity, gynecological history, as well as Rosenberg Self-Esteem Scale (SES) and Eating Attitude Test (EAT-26). Irregular menstrual cycles were observed in 236 (37.88%) girls; 5.20% presented secondary amenorrhea. Based on the EAT-26 test, 101 (16.21%) girls were indicated being at risk for an eating disorder. Low self-esteem was observed in 340 (54.57%) study girls on the base of SES. Girls with irregular menses had higher scores on the EAT-26 test in subscales: EAT-overall score, EAT-diet and EAT-bulimia, while lower scores on the SES. In our study, we did not observe a significant relationship between exercise intensity, body mass, BMI and menstrual cycle regularity. Low self-esteem among adolescent girls may be a risk factor for eating disorders which could interrupt the menstrual cycle.

    Full Text Available Abstract Background Research in the past decade has revealed average to poor menstrual health among many Iranian girls. The present study investigated the effectiveness of a health promotion project on improving menstrual health in adolescent girls in Iran. Methods A quasi-experimental study was conducted to evaluate the effectiveness of the health intervention program. A total of 698 students (study participants and controls in several schools in Mazandaran province, Iran were included. The project comprised 10 two-hour educational sessions. Educational topics included the significance of adolescence, physical and emotional changes during adolescence, pubertal and menstruation health and premenstrual syndrome. A self-administered questionnaire measuring demographic characteristics, behaviors during menstruation, menstrual patterns, sources of information about menstruation and personal health data was administered. The questionnaire was administered to all participating students after the experimental group received the training. Results Among the most significant results was the impact of educational sessions on bathing and genital hygiene. A total of 61.6% in the experimental group compared with 49.3% in the control group engaged in usual bathing during menstruation (p = 0.002. Individual health status was significantly statistically correlated with menstrual health. Attitude towards menstruation was also significantly related to menstrual health. Conclusions The present study confirms that educational interventions, such as the health promotion project in this study, can be quite effective in promoting menstrual health.

    To explore the influence of stress induced by the Wenchuan earthquake on the menstrual cycles of surviving women. Self-reports of the menstrual cycles of 473 women that survived the Wenchuan earthquake were analyzed. Menstrual regularity was defined as menses between 21 and 35 days long. The death of a child or the loss of property and social resources was verified for all surviving women. The severity of these losses was assessed and graded as high, little, and none. About 21% of the study participants reported that their menstrual cycles became irregular after the Wenchuan earthquake, and this percentage was significantly higher than before the earthquake (6%, p irregularity after the earthquake. Association analyses showed that some stressors of the Wenchuan earthquake were strongly associated with self-reports of menstrual irregularity, including the loss of children (RR: 1.58; 95% CI: 1.09, 2.28), large amounts of property (RR: 1.49; 95% CI: 1.03, 2.15), social resources (RR: 1.34; 95% CI: 1.00, 1.80) and the hormonal contraception use (RR: 1.62; 95% CI: 1.21, 1.83). Self-reported menstrual irregularity is common in women that survived the Wenchuan earthquake, especially in those who lost children, large amounts of property and social resources.

    The lack of noninvasive methods to study dysmenorrhea has resulted in poor understanding of the mechanisms underlying pain, insufficient diagnostic tests, and limited treatment options. To address this knowledge gap, we have developed a magnetic resonance imaging-based strategy for continuously monitoring the uterus in relationship to participants' spontaneous pain perception. The study objective was to evaluate whether magnetic resonance imaging can detect real-time changes in myometrial activity during cramping episodes in women with dysmenorrhea, with a handheld squeeze bulb for pain reporting. Sixteen women with dysmenorrhea and 10 healthy control women both on and off their menses were evaluated with magnetic resonance imaging while not taking analgesic medication. Continuous magnetic resonance imaging was acquired using half-Fourier acquisition single-shot turbo spin echo sequence along with simultaneous reporting of pain severity with a squeeze bulb. Pearson's coefficient was used to compare results between reviewers. Proportional differences between women with dysmenorrhea and controls on/off menses were evaluated with a Fisher exact test. The temporal relationships between signal changes were evaluated with Monte Carlo simulations. Spontaneous progressive decreases in myometrial signal intensity were more frequently observed in women on their menses than in the absence of pain in the same women off their menses or participants without dysmenorrhea (P < .01). Women without reductions in myometrial signal intensity on their menses either had a history of endometriosis or were not in pain. Observations of myometrial events were consistently reported between 2 raters blinded to menstrual pain or day status (r = 0.97, P < .001). Episodes of cramping occurred either immediately before or 32-70 seconds after myometrial signal change onset (P < .05). Transient decreases in myometrial uterine T2-weighted signal intensity can be reliably measured in women with

    Full Text Available Background: Submucous myomas may be associated with menorrhagia, infertility and dysmenorrhea. Objective: The aim of this study was to determine the long term effects of submucousal myoma resection on menorrhagia and infertility; also to detect whether the type, size, and location of myoma affect the surgical success. Materials and Methods: .Totally 98 women referred to hysteroscopy for symptomatic submucousal fibroids (menorrhagia (n=51 and infertility (n=47 between 2005- 2010 were enrolled in this historical cohort study Pregnancy rates and menstrual improvement rates were compared according to myoma characteristics (size, type and location. Results: After a mean postoperative period of 23±10 months in 51 patients with excessive bleeding, 13 had recurrent menorrhagia (25%. In Other 38 patients excessive bleeding was improved (75%. The improvement rates by location and myoma type: lower segment 100%, fundus 92%, and corpus 63%; type 0 70%, type 1 78%, type 2 80%. The mean sizes of myoma in recurred and improved patients were 23.33 mm and 29.88 mm respectively. 28 of 47 infertile women spontaneously experienced thirty pregnancies (60%. Pregnancy rates according to myoma location and type: lower segment 50%, fundus 57%, and corpus 80%; type 0 75%, type 1 62%, type 2 50%. The mean myoma size in patients who became pregnant was 30.38 mm; in patients who did not conceive was 29.95 mm. Conclusion: The myoma characetesitics do not affect improvement rates after hysteroscopic myomectomy in patients with unexplained infertility or excessive uterine bleeding.

    Recent studies have shown that women are more sensitive than men to subtle cuteness differences in infant faces. It has been suggested that raised levels in estradiol and progesterone may be responsible for this advantage. We compared young women's sensitivity to computer-manipulated baby faces varying in cuteness. Thirty-six women were tested once during ovulation and once during the luteal phase of their menstrual cycle. In a two alternative forced-choice experiment, participants chose the baby which they thought was cuter (Task 1), younger (Task 2), or the baby that they would prefer to babysit (Task 3). Saliva samples to assess levels of estradiol, progesterone and testosterone were collected at each test session. During ovulation, women were more likely to choose the cuter baby than during the luteal phase, in all three tasks. These results suggest that cuteness discrimination may be driven by cyclic hormonal shifts. However none of the measured hormones were related to increased cuteness sensitivity. We speculate that other hormones than the ones measured here might be responsible for the increased sensitivity to subtle cuteness differences during ovulation. Copyright © 2015 Elsevier Inc.

    Full Text Available About one-fifth of patients treated with levothyroxine have serum thyrotropin (TSH above target concentrations but, in approximately 15% of them, the cause of this TSH insufficient normalization remains unknown. We report the cases of two regularly menstruating women with known thyroid disease who had TSH levels consistently >3 mU/L (and sometimes above target levels during mid-cycle, but consistently lower serum levels during the follicular and luteal phases of menstrual cycle. A major TSH release by the thyrotrophs in response to high circulating levels of estradiol (E2 at mid-cycle may increase levels of TSH compared to other phases of the cycle. The increased TSH can be misinterpreted as refractory hypothyroidism if the woman is under L-T4 replacement therapy or as subclinical hypothyroidism if the woman is not. Our findings might have important implications for diagnosis and management of thyroid disease, suggesting to request serum TSH measurements outside of the periovulatory days.

    Full Text Available Abstract Background The aim of this paper is to empirically identify a treatment-independent statistical method to describe clinically relevant bleeding patterns by using bleeding diaries of clinical studies on various sex hormone containing drugs. Methods We used the four cluster analysis methods single, average and complete linkage as well as the method of Ward for the pattern recognition in menstrual bleeding diaries. The optimal number of clusters was determined using the semi-partial R2, the cubic cluster criterion, the pseudo-F- and the pseudo-t2-statistic. Finally, the interpretability of the results from a gynecological point of view was assessed. Results The method of Ward yielded distinct clusters of the bleeding diaries. The other methods successively chained the observations into one cluster. The optimal number of distinctive bleeding patterns was six. We found two desirable and four undesirable bleeding patterns. Cyclic and non cyclic bleeding patterns were well separated. Conclusion Using this cluster analysis with the method of Ward medications and devices having an impact on bleeding can be easily compared and categorized.

    Questionnaires were distributed to investigate body mass index (BMI) and menstrual patterns in female dancers aged 12 to 17 years. The study cohort consisted of 105 dancers, mean age 14.8 ± 1.1 years, and mean BMI 19.5 ± 2.3 kg/m 2 In all, 92% were healthy weight for height. First menses age ranged from 10 to 15 years (mean 12.9 ± 1.1 years). A total of 44% reported irregular menses; of those, 14% described irregularity as "every other month," 37% as "every 3 months," and 49% as "skips a month occasionally." A total of 36% of the dancers stop getting their menses during times of increased activity/dance, and 30% have gone >3 months at any time without getting their menses. A significant negative correlation between BMI and age of first menses was found with lower BMI associated with increased age of first menses (linear regression, β = -0.49,P= .021). This study supports an association between BMI and age of menarche among young female dancers. Given bone health reliance on hormonal milieu in female dancers, future research is warranted. © The Author(s) 2016.

    Introduction Fennel has many medicinal properties and is used in the treatment of dysmenorrhea. Given the widespread use of herbal medicine among women for menstrual problems and considering the fact that there has been no study to date about the effect of fennel on menstrual bleeding and duration of menstrual bleeding through systematic review, the present study was conducted to determine the effect of fennel on the amount (primary outcome) and duration of menstrual bleeding and its side-effects (secondary outcomes). Materials All articles, including Persian and English, with no time limit were searched for in the following databases: Medline (through PubMed), Scopus, EMBASE (through Ovid), Cochrane Library, Web of Sciences, Google Scholar, ProQuest, Clininaltrial.gov, SID, Magiran, Irandoc, and Iranmedex, using MeSH terms, including menstrual bleeding, menstruation, severity of bleeding, hypermenorrhea, menorrhagia, fennel, fennelin, Foeniculum vulgare, dysmenorrhea, and painful menstruation, which were searched separately or in combination. Two authors separately reviewed articles to determine the inclusion criteria, and any disagreement was resolved by reaching consensus with a third person. Results A total of 7993 articles were identified through searching the databases, of which 7327 were excluded as duplicates and 666 were screened for inclusion. Six hundread and forty six were excluded by title and abstract based on not being relevant to the review and being conducted on animals. Eventually, six articles were included in the study and four articles entered into the meta-analysis. The results from meta-analysis showed that using fennel caused a significant increase in mean menstrual bleeding in the first cycle after treatment in the intervention group compared to the control (Std. mean difference: 0.46; 95 % CI: 0.18-0.73; p = 0.001; I2 = 9 %). However, it had no significant effect on menstrual bleeding in the second cycle after treatment (Mean

    The differentiation of blood and menstrual fluid is especially important in cases of alleged sexual assault. While the identification of blood is relatively straightforward, the identification of menstrual fluid in trace evidence has been shown to be more challenging. This may be due to the complex nature of menstrual fluid that leads to intra- and inter-individual differences in composition. Nevertheless, recent advances in DNA methylation profiling have revealed promising markers for the differentiation of the two body fluids and furthermore, markers to distinguish menstrual fluid from vaginal fluid. A literature study was performed and in total, 11 markers were evaluated in this study of which seven could be validated for menstrual fluid and blood identification purposes. Marker "BLU2" (chr16:29757334) was identified as most suitable for differentiation of blood and menstrual fluid.

    This study presents a 13-dimensional system of delayed differential equations which predicts serum concentrations of five hormones important for regulation of the menstrual cycle. Parameters for the system are fit to two different data sets for normally cycling women. For these best fit parameter sets, model simulations agree well with the two different data sets but one model also has an abnormal stable periodic solution, which may represent polycystic ovarian syndrome. This abnormal cycle occurs for the model in which the normal cycle has estradiol levels at the high end of the normal range. Differences in model behavior are explained by studying hysteresis curves in bifurcation diagrams with respect to sensitive model parameters. For instance, one sensitive parameter is indicative of the estradiol concentration that promotes pituitary synthesis of a large amount of luteinizing hormone, which is required for ovulation. Also, it is observed that models with greater early follicular growth rates may have a greater risk of cycling abnormally.

    Introduction  The hormonal changes that occur during the menstrual cycle and their relationship with hearing problems have been studied. However, they have not been well explained. Objective  The objective of our study is to investigate the variation in hearing thresholds in women during the menstrual cycle. Method  We conducted a cohort and longitudinal study. It was composed of 30 volunteers, aged 18-39 years old, of which 20 were women during the phases of the menstrual cycle and 10 were men (control group) who underwent audiometry and impedance exams, to correlate the possible audiological changes in each phase of the menstrual cycle. Results  There were significant changes in hearing thresholds observed during the menstrual cycle phases in the group of women who used hormonal contraceptives and the group who did not use such contraceptives. Improved hearing thresholds were observed in the late follicular phase in the group who did not use hormonal contraceptives and the hearing thresholds at high frequencies were better. Throughout the menstrual cycle phases, the mean variation was 3.6 db HL between weeks in the group who used hormonal contraceptives and 4.09 db HL in the group who did not use them. Conclusions  The present study found that there may be a relationship between hearing changes and hormonal fluctuations during the menstrual cycle based on changes in the hearing thresholds of women. In addition, this study suggests that estrogen has an otoprotective effect on hearing, since the best hearing thresholds were found when estrogen was at its maximum peak.

    Information on pattern of menstruation and its implications is lacking amongst adolescents in Nigeria. To examine the characteristics of menstruation amongst adolescent Igbo school girls with respect to the biosocial characteristics, the pattern of menstruation, associated complications, and the source of information on menstruation. A descriptive cross-sectional study of 550 students recruited from a multi-sampling of 50 secondary schools in Onitsha, Anambra State, Nigeria, using pre-tested, semistructured, and interviewer administered questionnaires. Four hundred and sixteen (75.6%) respondents were aged 15-17 years; 338 (61.4%) of whom were Catholics. Menarcheal age range of respondents was 11-16 years, with a mean age of 13.40 +/- 1.15 years. Menstruation was regular in 410 (74.5%), and irregular in 124 (22.5%) of respondents. Duration of menstrual flow ranged between two and eight days, although a four-day flow occurred most commonly, 268 (53.6%). Abdominal pain, (66.2%), and waist pain, (38.5%), constituted the major problems associated with menstruation, followed by depression, (24.4%); vomiting, (6.9%); school absenteeism, (4.5%); anorexia, (1.8%); weakness, (1.5%); and increased appetite, (1.1%). The commonest source of information on menstruation (prior to menarche) amongst respondents was from the mother, 48.4%, followed by elder sister, and friends --14.2%, and 8.7% respectively, while the teacher constituted the least source, 1.1%. The characteristics of menstruation in this study do not differ considerably from what obtains amongst other adolescent girls. Associated complications may have profound psychosocial impact on the growing adolescent girl, requiring address, best achieved through the empowerment of mothers and teachers under a comprehensive family life education scheme.

    This experiment was conducted to compare conventional (CON; 21 d) and shortened (SH; 10 d) close-up period, and evaluate the effect of shortened close-up period combined with feeding different metabolizable protein (MP) levels on dry matter (DM) intake, metabolic status, and performance of dairy cows. Forty-eight multiparous Holstein cows with similar parity, body weight (BW), and previous lactation milk yield were divided into 2 groups. The first group (n = 24) received the far-off diet from -60 to -21 d (CON), and the second group (n = 24) received same far-off diet from -60 to -10 d (SH) relative to expected parturition. Cows were then moved to individual stalls and randomly allocated to 1 of 3 close-up diets: low MP diet (LMP; MP = 79 g/kg of DM), medium MP diet (MMP; MP = 101 g/kg of DM), or high MP diet (HMP; MP = 118 g/kg of DM). Treatments were used in a 2 × 3 factorial arrangement with 2 lengths of close-up period (CON and SH) and 3 levels of MP (LMP, MMP, and HMP). All diets were fed for ad libitum intake during the close-up period. After calving, all cows received the same fresh cow diet. We found no interaction between close-up period length and MP levels for traits, except for postpartum serum fatty acids and β-hydroxybutyrate (BHB). The concentrations of postpartum serum fatty acids and BHB were higher on LMP than MMP and HMP diets in SH group. The cows of the SH group tended to produce less colostrum in the first milking than cows in CON group. The length of close-up period did not affect pre- and postpartum DM intake or energy balance of cows during the last week of prepartum, but cows of the CON group had greater BW changes during the last 3 wk before parturition than cows in SH group. Cows fed MMP and HMP diets consumed 1.2 and 1 kg more DM than for those fed LMP prepartum, respectively. The concentrations of prepartum BHB and Ca were higher for SH cows than CON group cows. Except for blood urea N concentration, no other blood metabolite in

    The issue of menstrual hygiene is inadequately acknowledged and has not received proper attention. Use of sanitary pads and washing the genital area are essential practices to keep the menstrual hygiene. Unhygienic menstrual practices can affect the health of the girls and there is an increased vulnerability to reproductive tract infections and pelvic inflammatory diseases and other complications. Therefore, the objective of this study was to assess the knowledge and practice of menstrual hygiene among high school girls at Nekemte town, Oromia region, Western Ethiopia. A school based cross-sectional study design was employed in Nekemte Town, Western Ethiopia. A multi stage sampling technique was used to select 828 female high school students. Data collection was carried out from May 04 to May 30, 2014 using a pre- tested structured questionnaire. The data were entered into a computer using Epi-info version 3.5.1 and then exported to SPSS for Windows version 20.0 for analysis. Bivariate and multivariate logistic regression analysis was done at 95 % confidence interval. In this study, 504 (60.9 %) and 330 (39.9 %) respondents had good knowledge and practice of menstrual hygiene respectively. The findings of the study showed a significant positive association between good knowledge of menstruation and educational status of mothers (AOR = 1.51, 95 % CI = 1.02 - 2.22), having radio/TV (AOR = 2.42, 95 % CI: 1.64 - 3.56). Educational status of the mother (AOR = 2.03, 95 % CI = 1.38 - 2.97) and earning permanent pocket money from parents (AOR = 2.73, 95 % CI = 1.76 - 4.26) revealed significant positive association with good practice of menstrual hygiene. The findings showed that the knowledge and practice of menstrual hygiene is low. Awareness regarding the need for information about good menstrual practices is very important. So, health education program should be setup to create awareness and practice of good menstrual hygiene.

    Objectives: To assess the apparent diffusion coefficient (ADC) changes of the normal uterine zones among reproductive women during the menstrual cycle. Methods: The study included 101 women of reproductive age, each with regular cycle and normal endometrium/myometrium, as proved on histopathology or MR imaging examination. Diffusion-weighted (DW) imaging was performed along the axial plane, using a single shot, multi-slice spin-echo planar diffusion pulse sequence and b-values of 0 and 800 s/mm 2 . The mean and standard deviation of the ADC values of normal endometrium/myometrium were calculated for menstrual, proliferative and secretory phase. Analysis of variance followed by the least significant difference test was used for statistical analysis. Results: The ADC values of the endometrium were different in the three phases of the menstrual cycle (menstrual phase: 1.25 ± 0.27; proliferative phase: 1.39 ± 0.20; secretory phase: 1.50 ± 0.18) (F: 9.64, p: 0.00). Statistical significant difference was observed among all groups (p 0.05). Conclusions: A wide variation of ADC values of normal endometrium and myometrium is observed during different phases of the menstrual cycle.

    Polycystic ovary syndrome is characterized by irregular cycles, hyperandrogenism, polycystic ovary at ultrasound and insulin resistance. The effectiveness of D-chiro-inositol (DCI) treatment in improving insulin resistance in PCOS patients has been confirmed in several reports. The objective of this study was to retrospectively analyze the effect of DCI on menstrual cycle regularity in PCOS women. This was a retrospective study of patients with irregular cycles who were treated with DCI. Of all PCOS women admitted to our centre, 47 were treated with DCI and had complete medical charts. The percentage of women reporting regular menstrual cycles significantly increased with increasing duration of DCI treatment (24% and 51.6% at a mean of 6 and 15 months of treatment, respectively). Serum AMH levels and indexes of insulin resistance significantly decreased during the treatment. Low AMH levels, high HOMA index, and the presence of oligomenorrhea at the first visit were the independent predictors of obtaining regular menstrual cycle with DCI. In conclusion, the use of DCI is associated to clinical benefits for many women affected by PCOS including the improvement in insulin resistance and menstrual cycle regularity. Responders to the treatment may be identified on the basis of menstrual irregularity and hormonal or metabolic markers.

    The aim of this study was to assess the nutritional status and dietary habits of young women, in order to explore their relationship with the menstrual cycle and to determine the proportion of women with menstrual cycle irregularities. A total of 348 young women aged 15-25 years (19.7 ± 3.7 years) participated in the study and were assigned to a younger group (15-18 years; YG) or an older group (19-25 years; OG). Two subgroups were also distinguished: women with menstrual disorders (MD) and women with regular cycles (RC). Body mass, waist circumference, fat mass (FM), energy and nutrient intakes, and eating behaviour of the subjects were evaluated. In both age groups, women with menstrual cycle disorders were more likely to have higher body weight, higher body mass index, larger waist circumference and higher body FM. The daily diets of these women contained larger quantities of animal protein and fat, including saturated fat (in OG), but were poorer in vitamins B 1 and B 6 (in YG) and in iron. Disinhibition was significantly more common in the MD group. The results of this study suggest that nutritional habits and status can interfere with the course of the menstrual cycle in young women. © 2017 Dietitians Association of Australia.

    Full Text Available Background and Objective: Over a century, an increased prevalence of gingival disease associated with increasing plasma sex steroid hormone levels has been reported. These situations present unique challenges to the oral health care professional. It is believed that hormonal fluctuations such as those associated with pregnancy, menstruation, and use of hormonal contraceptives lead to an increase in tooth mobility. However, this effect of female sex hormones on periodontal ligament and tooth supporting alveolar bone has rarely been investigated. So this study was undertaken to understand the effect on tooth mobility because of hormonal changes during the menstrual cycle. Materials and Methods: The mobility of index teeth 16, 13, 21, 23, 24, 36, 33, 41, 43, and 44 was measured with Periotest in 50 females at menstruation, ovulation, and premenstruation time points. Simplified oral hygiene index, plaque index, gingival index, and probing depth were also evaluated during the different phases of menstrual cycle for each subject participating in the study. Statistical Analysis: The results of the study were subjected to statistical analysis. Data analysis was done by applying Z test for comparing difference between two sample means. Result: The stages of menstrual cycle had no significant influence on the Periotest value. Despite no significant change in plaque levels, GI was significantly higher during ovulation and premenstruation time points. Conclusion: No change in tooth mobility was seen during the phases of the menstrual cycle. However, an exaggerated gingival response was seen during ovulation and premenstruation time when the entire menstrual cycle was observed.

    Elastography is a novel technique capable of noninvasively assessing the elastic properties of breast tissue. Because the risk factors for breast cancer include hormonal status and proliferation, the aim of our study was to estimate the intensity of sonoelastographic changes during the menstrual cycle. Eight women aged 20-23 years with regular menstrual cycles underwent B-mode sonography and sonoelastography (ShearWave on Aixplorer, France) on days 3, 10, 17 and 24. Mean values of glandular and fat tissue elasticity did not change statistically significantly during the menstrual cycle as well as glandular to fat tissue ratio. During almost the whole cycle differences between outer and inner quadrants in glandular and fat tissue were statistically significant. The lowest values of elasticity occurred on the 10th day and the highest on the 24th of the menstrual cycle. There were statistically significant differences in elasticity between inner and outer quadrants of both breasts close to day 3 and 17 of the menstrual cycle.

    Heavy menstrual bleeding (HMB) is common and incapacitating. Aberrant menstrual endometrial repair may result in HMB. The transforming growth factor (TGF)-β superfamily contributes to tissue repair, but its role in HMB is unknown. We hypothesized that TGF-β1 is important for endometrial repair, and women with HMB have aberrant TGF-β1 activity at menses. Endometrial biopsies were collected from women, and menstrual blood loss objectively measured [HMB >80 mL/cycle; normal menstrual bleeding (NMB) endometrial TGF-β1 ligand, receptors, and downstream SMADs in women with NMB and HMB. The function and regulation of TGF-β1 were examined using cell culture. TGFB1 mRNA was maximal immediately prior to menses, but no differences detected between women with NMB and HMB at any cycle stage. Histoscoring of TGFB1 revealed reduced staining in the stroma during menses in women with HMB (P endometrial stromal cells (HES; P Endometrial SMAD2 and SMAD3 were lower in women with HMB during menstruation (P scratch assays revealed increased repair in HES cells treated with TGF-β1 versus control (P endometrial stromal cell repair. Decreased TGF-β1 activity may hinder repair of the denuded menstrual endometrium, resulting in HMB. Copyright © 2017 by the Endocrine Society

    Full Text Available Objective: To investigate the etiology of menstrual disorders among patients undergoing hemodialysis due to chronic renal failure by assessing menstrual history, serum hormone levels, and other biochemical factors. Material and methods: Thirty patients undergoing hemodialysis and 30 healthy women at reproductive age were enrolled in our study. Demographic characteristics, hormonal and biochemical data, and sonographically measured endometrial thickness values of the subjects were compared. In addition, the present and the pre-hemodialysis menstrual pattern of the patients undergoing hemodialysis were recorded. The hormonal, hematological, and biochemical data of the patients were compared according to their menstrual patterns. Results: No statistical significance was seen between age, BMI, gravida, parity, abortion, and curettage among groups (p>0.05. Hemoglobin and hematocrit levels were significantly lower in the hemodialysis group than in the control (p0.05. Mean serum LH and prolactin levels were significantly higher in the hemodialysis group compared to the control (p0.05. Serum LH and prolactin levels were higher, and serum FSH, estradiol and TSH levels were lower in patients who developed amenorrhea after hemodialysis treatment when compared to non-amenorrheic subjects. However, these differences were not statistically significant (p>0.05. Discussion: The most important factor in the etiology of menstrual disorders seen in chronic renal failure patients was high serum LH and prolactin levels. Hemodialysis is a successful treatment that extends life expectancy and ameliorates the hypothalamo-pituitary-ovarian axis in chronic renal failure patients.

    Physique competitions are events in which competitors are judged on muscular appearance and symmetry. The purpose of this retrospective case study was to describe changes in dietary intake, body mass/composition, and the menstrual cycle during the 20-week competition preparation (PREP) and 20-week post competition recovery (REC) periods of a drug-free amateur female figure competitor (age = 26–27, BMI = 19.5 kg/m2). Dietary intake (via weighed food records) and body mass were assessed daily and averaged weekly. Body composition was estimated via Dual-energy X-ray absorptiometry (DXA) and 7-site skinfold measurements. Energy intake, body mass and composition, and energy availability decreased during the 20-week PREP period (changes of ~298 kcals, 5.1 kg, 6.5% body fat, and 5.4 kcal/kg fat free mass, respectively) and returned to baseline values by end of the 20-week REC period. Menstrual cycle irregularity was reported within the first month of PREP and the last menstruation was reported at week 11 of PREP. Given the potentially adverse health outcomes associated with caloric restriction, future, prospective cohort studies on the physiological response to PREP and REC are warranted in drug-free, female physique competitors.

    We describe a patient with mild hyperprolactinemia and menstrual disorders (oligomenorrhea). She presented relative hypoestrogenism in laboratory tests. Magnetic resonans excluded the presence of pituitary adenoma. Because patient developed a bromocriptine intolerance, the Vitex Agnus Castus (VAC) extract has been introduced. The VAC therapy was effective, with symptoms relief and improvement of hormonal tests. The VAC medicines are indicated for the treatment of premenstrual syndrome (PMS), mastalgia, menstrual disorders and mild hyperprolactinemia. The mechanism of action is not fully understood, but it is related to dopaniergic activity of diterpenes and castacin in VAC. The randomized clinical trials revealed efficacy of VAC extract in the treatmet of hyperprolactinemia, menstrual disorders, PMS and mastalgia. Good tolerability, lack of serious side-effects and drug interactions are the advantages of the VAC preparations. © 2015 MEDPRESS.

    A wide range of herbal plants have been reported to treat various gynecological problems of women. This study was set out to investigate the effect of ginger (Zingiber officinale) on heavy menstrual bleeding (HMB) in high school girls. Ninety-two young women who experienced HMB and met the inclusion criteria were recruited in this study. Participants were evaluated for six consecutive menstrual cycles. During 3 assessment cycles, their HMB was confirmed by Pictorial Blood Assessment Chart. They were then randomly allocated to two study groups to receive either ginger or placebo capsules. The participants filled in the same chart during three intervention cycles. The level of menstrual blood loss dramatically declined during the three intervention cycles in ginger-receiving group. The decrease of blood loss in ginger-receiving group was significantly more remarkable than that of participants receiving placebo (pginger may be considered as an effective therapeutic option for HMB.

    To investigate whether medical treatment with tranexamic acid would increase the quality of life of women with heavy menstrual bleeding. This open, uncontrolled usage study included 849 women diagnosed with heavy menstrual bleeding and considered eligible for tranexamic-acid treatment. The condition of the women was investigated at baseline and after the first and the third treated menstruation. Quality of life and subjectively experienced state of health were assessed with the aid of a questionnaire. Satisfaction with the treatment was registered. After the third menstruation, 80% of the women were satisfied with the treatment. Impairment of social activities and impairment at work were greatly reduced by the treatment. Substantial improvements were also recorded with regard to alertness, productivity, cleanliness, spirits, action radius and overall well-being. Adverse reactions to the drug used for the treatment were few and non-serious. Medical treatment with tranexamic acid increases quality of life for women with heavy menstrual bleeding.

    Menstrual and reproductive factors, including age at menarche, parity, and breastfeeding, have been linked to type 2 diabetes risk. We prospectively investigated the association between these factors and type 2 diabetes risk in a large Japanese cohort. Participants were 37,511 women aged 45-75 years who participated in the baseline (1990-1993), second (1995-1998), and third surveys (2000-2003) of the Japan Public Health Center-based Prospective Study and who had no history of diabetes at the second survey. Menstrual and reproductive history was ascertained using questionnaires at the baseline and second surveys. Odds ratios of self-reported, physician-diagnosed type 2 diabetes over the 5-year period from the second survey were estimated using logistic regression. At the third survey, 513 new cases of type 2 diabetes were self-reported. The odds ratios of type 2 diabetes tended to increase with the number of parity, after adjustment for covariates other than body mass index (P for trend = 0.029). The multivariable-adjusted odds ratios (95% confidence interval) of type 2 diabetes for women with ≥3 births was 1.56 (0.96-2.53) compared to those who were nulliparous. The association between parity and type 2 diabetes risk was attenuated after additional adjustment for body mass index (P for trend = 0.12). No factors other than parity were significantly associated with type 2 diabetes risk. Higher parity may be associated with increased risk of type 2 diabetes among Japanese women, partly through increasing body weight. This article is protected by copyright. All rights reserved.

    2018-04-30

    Menstrual pain is highly prevalent among women of reproductive age. As the general public increasingly obtains health information online, Big Data from online platforms provide novel sources to understand the public's perspectives and information needs about menstrual pain. The study's purpose was to describe salient queries about dysmenorrhea using Big Data from a question and answer platform. We performed text-mining of 1.9 billion queries from ChaCha, a United States-based question and answer platform. Dysmenorrhea-related queries were identified by using keyword searching. Each relevant query was split into token words (i.e., meaningful words or phrases) and stop words (i.e., not meaningful functional words). Word Adjacency Graph (WAG) modeling was used to detect clusters of queries and visualize the range of dysmenorrhea-related topics. We constructed two WAG models respectively from queries by women of reproductive age and bymen. Salient themes were identified through inspecting clusters of WAG models. We identified two subsets of queries: Subset 1 contained 507,327 queries from women aged 13-50 years. Subset 2 contained 113,888 queries from men aged 13 or above. WAG modeling revealed topic clusters for each subset. Between female and male subsets, topic clusters overlapped on dysmenorrhea symptoms and management. Among female queries, there were distinctive topics on approaching menstrual pain at school and menstrual pain-related conditions; while among male queries, there was a distinctive cluster of queries on menstrual pain from male's perspectives. Big Data mining of the ChaCha ® question and answer service revealed a series of information needs among women and men on menstrual pain. Findings may be useful in structuring the content and informing the delivery platform for educational interventions.

    The purpose of this study was to assess the menstrual cycle, menstrual disorders and premenstrual syndrome/premenstrual dysphoric disorder (PMS/PMDD) in girls and young women participating in competitive sports. The impact of PMS/PMDD symptoms on the quality of life was also analyzed. The prospective study encompassed 125 girls and young women with the aim to determine the presence of menstrual disorders and the prevalence of PMS/PMDD. The studied group was composed of 75 female athletes aged 16 to 22 years. The control group included 50 healthy girls and young women who did not practice competitive sports. The studied athletes and the controls prospectively evaluated their 2 consecutive menstrual cycles by using a questionnaire. The research tools were a purpose-built questionnaire, a daily log of PMS symptoms according to the American College of Obstetricians and Gynecologists' guidelines, and a daily log of PMDD symptoms based on the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, diagnostic criteria. To determine the impact of competitive sports on the menstrual cycle, menstrual disorders, and the prevalence of PMS/PMDD in girls and young women. Intensive physical exercise delayed menarche. PMDD was diagnosed in 8% and PMS in 42.4% of all respondents. The prevalence of PMDD did not differ significantly between the groups (9.33% versus 6.00%). PMS was significantly more frequent among athletes than among controls (49.33% versus 32%, P = .045). The prevalence of PMS correlated significantly with mean age (P = .00001) and age at menarche (P = .03) in athletes. PMS was more frequent in older athletes and in girls with older age at menarche. Competitive sports, older mean age, older age at menarche, length of sporting career, and intensity of training are conducive to PMS. The prevalence of PMS increases with the duration and intensification of competitive exercises. Copyright © 2015 North American Society

    The main aim of this study was to investigate whether there is a relationship between menstrual cycle phase and exercise-induced bronchoconstriction (EIB) in female athletes with mild atopic asthma. Seven eumenorrheic subjects with regular 28-day menstrual cycles were exercised to volitional exhaustion on day 5 [mid-follicular (FOL)] and day 21 [mid-luteal (LUT)] of their menstrual cycle. Pulmonary function tests were conducted pre- and post-exercise. The maximal percentage decline in post-exercise forced expiratory volume in 1 s (FEV(1)) and forced expiratory flow from 25 to 75% of forced vital capacity (FEF(25-75%)) was significantly greater (Pphase) (-17.35+/-2.32 and -26.28+/-6.04%, respectively), when salivary progesterone concentration was highest, compared to day 5 (mid-FOL phase) (-12.81+/-3.35 and -17.23+/-8.20%, respectively), when salivary progesterone concentration was lowest. The deterioration in the severity of EIB during the mid-LUT phase was accompanied by worsening asthma symptoms and increased bronchodilator use. There was a negative correlation between the percent change in pre- to post-exercise FEV(1) and salivary progesterone concentration. However, no such correlation was found between salivary estradiol and the percentage change in pre- to post-exercise FEV(1). This study has shown for the first time that menstrual cycle phase is an important determinant of the severity of EIB in female athletes with mild atopic asthma. Female asthmatic athletes may need to adjust their training and competition schedules to their menstrual cycle and to consider the potential negative effects of the LUT phase of the menstrual cycle on exercise performance.

    Exposure to ozone (O[sub 3]), a toxic component of photochemical smog, results in significant airway inflammation, respiratory discomfort, and pulmonary function impairment. These effects can be reduced via pretreatment with anti-inflammatory agents. Progesterone, a gonadal steroid, is known to reduce general inflammation in the uterine endometrium. However, it is not known whether fluctuation in blood levels of progesterone, which are experienced during the normal female menstrual cycle, could alter O[sub 3] inflammatory-induced pulmonary responses. In this study, we tested the hypothesis that young, adult females are more responsive to O[sub 3] inhalation with respect to pulmonary function impairment during their follicular (F) menstrual phase when progesterone levels are lowest that during their mid-luteal (ML) phase when progesterone levels are highest. Nine subjects with normal ovarian function were exposed in random order for 1 hour each to filtered air and to 0.30 ppm O[sub 3] in their F and ML menstrual phases. Ozone responsiveness was measured by percent change in pulmonary function from pre- to postexposure. Significant gas concentration effects (filtered air versus O[sub 3]) were observed for forced vital capacity (FVC), forced expiratory volume in 1 sec (FEV[sub 1]), and forced expiratory flow between 25 and 75% of FVC (FEF[sub 25-75]), showed a significant menstrual phase and gas concentration interaction effect, with larger decrements observed in the F menstrual phase when progesterone concentrations were significantly lower. We conclude that young, adult females appear to be more responsive to acute O[sub 3] exposure during the F phase than during the ML phase of their menstrual cycles. This difference in pulmonary function response could be related to the anti-inflammatory effects of increased progesterone concentrations during the luteal phase.

    Previous studies have reported that hyperthyroid and hypothyroid women experience menstrual irregularities more often compared with euthyroid women, but reasons for this are not well-understood and studies on thyroid hormones among euthyroid women are lacking. In a prospective cohort study of euthyroid women, this study characterised the relationship between thyroid hormone concentrations and prospectively collected menstrual function outcomes. Between 2004-2014, 86 euthyroid premenopausal women not lactating or taking hormonal medications participated in a study measuring menstrual function. Serum thyroid hormones were measured before the menstrual function study began. Women then collected first morning urine voids and completed daily bleeding diaries every day for three cycles. Urinary oestrogen and progesterone metabolites (estrone 3-glucuronide (E 1 3G) and pregnanediol 3-glucuronide (Pd3G)) and follicle-stimulating hormone were measured and adjusted for creatinine (Cr). Total thyroxine (T 4 ) concentrations were positively associated with Pd3G and E 1 3G. Women with higher (vs lower) T 4 had greater luteal phase maximum Pd3G (Pd3G = 11.7 μg/mg Cr for women with high T 4 vs Pd3G = 9.5 and 8.1 μg/mg Cr for women with medium and low T 4 , respectively) and greater follicular phase maximum E 1 3G (E 1 3G = 41.7 ng/mg Cr for women with high T 4 vs E 1 3G = 34.3 and 33.7 ng/mg Cr for women with medium and low T 4 , respectively). Circulating thyroid hormone concentrations were associated with subtle differences in menstrual cycle function outcomes, particularly sex steroid hormone levels in healthy women. Results contribute to the understanding of the relationship between thyroid function and the menstrual cycle, and may have implications for fertility and chronic disease. © 2018 John Wiley & Sons Ltd.

    Menstrual disorders and sexual harassment are common among young women and interfere with their life and activities. We aimed to describe the association of sexual harassment and menstrual disorders among female university students. This cross-sectional, observational study examined the association between sexual harassment and menstrual disorders in a sample of 349 university students in Italy. Students answered an anonymous self-administered questionnaire. Descriptive bivariate analyses and logistic regression analyses were performed. Main outcome measures were associations between levels of exposure to sexual harassment (none, levels 1 and 2) and five menstrual disorders (premenstrual symptoms, heavy bleeding, pain, irregular cycles, and amenorrhea). Among the women interviewed (mean age 20.4 ± 1.45 years), 146 (41.8%) had experienced sexual harassment in the previous 12 months: 91 (26.1%) level 1 and 55 (15.7%) level 2. The frequency of premenstrual symptoms was 31.9% ( n=110); heavy bleeding, 35.3% ( n=124); pain, 51.4% ( n=181); irregular cycles, 55.5% ( n=195); and amenorrhea, 6.7% ( n=23). After adjustment for age, place of birth, being in a couple relationship and receiving hormone therapy, the frequency of menstrual disorders, except for amenorrhea, was increased with sexual harassment, with a regular gradient from no harassment to level 2 harassment. Introducing factors of depression, specific gynaecological problems and lifetime sexual violence did not change the results. For instance, the adjusted odds ratios of premenstrual symptoms were 2.10 [1.19-3.68] for women with level 1 harassment and 3.58 [1.83-7.03] for women with level 2 compared with women without harassment exposure. Sexual harassment is related to the prevalence of menstrual disorders. Healthcare providers should encourage dialogue with patients and address the issue of sexual violence or harassment.

    Human epididymis protein 4 is a serum biomarker to aid in differentiating benign and malignant disease in women with a pelvic mass. Interpretation of human epididymis protein 4 results relies on robust normative data. The purpose of this study was to evaluate whether human epididymis protein 4 levels are variable in women during the normal menstrual cycle. Healthy women, 18-45 years old, with regular menstrual cycles were recruited from community gynecologic practices in Rhode Island. Women consented to enroll and to participate by the donation of blood and urine samples at 5 specific times over the course of each cycle. Levels of reproductive hormones and human epididymis protein 4 were determined. Data were analyzed with the use of linear regression after log transformation. Among 74 enrolled cycles, 53 women had confirmed ovulation during the menstrual cycle and completed all 5 sample collections. Levels of estradiol, progesterone, and luteinizing hormone displayed the expected menstrual cycle patterns. Levels of human epididymis protein 4 in serum were relatively stable across the menstrual cycle, except for a small ovulatory (median, 37.0 pM) increase. Levels of human epididymis protein 4 in urine, after correction for creatinine, displayed the same pattern of secretion observed in serum. Serum human epididymis protein 4 levels are relatively stable across the menstrual cycle of reproductive-aged women and can be determined on any day to evaluate risk of ovarian malignancy. A slight increase is expected at ovulation; but even with this higher human epididymis protein 4 level, results are well within the healthy reference range for women (<120 pM). Levels of human epididymis protein 4 in urine warrant further investigation for use in clinical practice as a simple and convenient sample. Copyright © 2017 Elsevier Inc. All rights reserved.

    The association between phases of the menstrual cycle and body image was investigated. 44 university women (M age = 23.3 yr., SD = 4.7) judged their perceived and ideal body size, and body dissatisfaction was calculated at each phase of the menstrual cycle, including premenstrual, menstrual, and intermenstrual. Participants selected one of nine figural drawings ranging from very thin to obese that represented their perceived size and ideal size. Body dissatisfaction was measured as the absolute difference between scores on perceived and ideal figural drawings. During each menstrual phase, anthropometric measures of weight, height, body mass index, circumference of waist and abdomen, and body composition were taken. There were no significant differences in any anthropometric measures between the three menstrual cycle phases. Perceived body size and body dissatisfaction were significantly different between menstrual phases, with the largest perceived body size and highest body dissatisfaction occurring during the menstrual phase. Ideal body size did not differ between menstrual phases, although participants desired a significantly smaller ideal size as compared to the perceived size.

    A yearly multi-round, multi-period, multi-product transmission rights (TR) auction issuing both point-to-point Financial Transmission Rights (FTRs) and Flow-Gate Rights (FGRs) is studied in this paper. In each round the TR market participants (buyers or sellers) submit their bid or offer prices based on past energy market performance. A Locational Marginal Pricing (LMP) based energy market is assumed. The TR market participants' bid or offer prices reflect their expectation of the average annual LMP differences between withdrawal and injections points for FTRs and of the transmission link capacity prices for FGRs. The TR auction is performed in four rounds; in each round 25% of the entire system capability is awarded. TRs that are awarded in one round are modeled as fixed injections in subsequent rounds. Market participants that have acquired TRs in one round can sell them in subsequent rounds. A market participant can submit bids or offers for on-peak, off-peak or 24-h TRs. A three-area, nine-bus test system with six TR market participants is used for the analysis of the TR auction. (author)

    Obesity has adverse effects on ovulation, menstrual cyclicity and oocyte development leading to clinical symptoms such as infertility and menstrual disorders. The Roux-en-Y gastric bypass (RYGB) leads to weight loss, improved insulin sensitivity and may improve ovarian function. In 31 premenopausal...... women, 18 eu- and 13 oligo-/amenorrhoic, we followed the changes in follicular phase sex hormones 3, 6 and 12 month after RYGB. The average weight loss during the first postoperative year was 39.6 kg. The insulin sensitivity and serum insulin improved markedly especially within the first three...

    Menstrual hygiene management (MHM) is an essential aspect of hygiene for women and adolescent girls between menarche and menopause. Despite being an important issue concerning women and girls in the menstruating age group MHM is often overlooked in post-disaster responses. Further, there is limited evidence of menstrual hygiene management in humanitarian settings. This study aims to describe the experiences and perceptions of women and adolescent girls on menstrual hygiene management in post-earthquake Nepal. A mixed methods study was carried out among the earthquake affected women and adolescent girls in three villages of Sindhupalchowk district of Nepal. Data was collected using a semi-structured questionnaire that captured experiences and perceptions of respondents on menstrual hygiene management in the aftermath of the Nepal earthquake. Quantitative data were triangulated with in-depth interview regarding respondent's personal experiences of menstrual hygiene management. Menstrual hygiene was rated as the sixth highest overall need and perceived as an immediate need by 18.8% of the respondents. There were 42.8% women & girls who menstruated within first week of the earthquake. Reusable sanitary cloth were used by about 66.7% of the respondents before the earthquake and remained a popular method (76.1%) post-earthquake. None of the respondents reported receiving menstrual adsorbents as relief materials in the first month following the earthquake. Disposable pads (77.8%) were preferred by respondents as they were perceived to be clean and convenient to use. Most respondents (73.5%) felt that reusable sanitary pads were a sustainable choice. Women who were in the age group of 15-34 years (OR = 3.14; CI = (1.07-9.20), did not go to school (OR = 9.68; CI = 2.16-43.33), married (OR = 2.99; CI = 1.22-7.31) and previously used reusable sanitary cloth (OR = 5.82; CI = 2.33-14.55) were more likely to use the reusable sanitary cloth.

    Using a specific and sensitive radioimmunoassay, the authors determined levels of inhibin-like material in the urine of eight healthy women with normal menstrual cycle length of 28 +- 4 days. The results revealed a cyclic variation in urinary immunoreactive inhibin levels during the menstrual cycles, with a sharp rise in levels three to four days prior to luteinizing hormone (LH) and follicle-stimulating hormone (FSH) peaks. These levels of immunoreactive inhibin may thus serve as a parameter to detect impending LH surge. 23 refs.

    Cytogenetic analyses were performed in thirty, otherwise genitally and extragenitally unaffected, female X-ray assistants with menstrual disturbances (oligomenorrhea, secondary amenorrhea, irregular bleedings, hypermenorrhea) developing in the course of occupational experience under intermittent, chronic, low-level exposure conditions, the dose accumulated remaining below the maximum permissible dose. Seventeen of these subjects showed changes in chromosome constitution, namely: aneuploidy, up to 34,2%; breaks, 2 - 14,3%; gaps, 5,6 - 16,7;; and dicentrics, in one case, 2,8%. Increase in occupational experience was found to be associated with increase in percentage of menstrual disturbances and in chromosome aberrations. (author)

    1. It is known that females have a lower skin perfusion than males. In women there are also differences in blood flow at different reproductive stages of their lives. As an initial investigation of the possible contribution of sex hormones to these differences, we studied skin and forearm blood flow during the natural changes in hormone levels which occur during the menstrual cycle. 2. Thirty-one healthy female volunteers were studied. The effect of a standardized finger cooling test (immersion of a gloved hand in a 16 degrees C water bath) on finger skin temperature and on laser Doppler flux in the finger, and forearm blood flow (strain gauge venous occlusion plethysmography) was assessed at four different times during one cycle: during menstruation, 1 day before ovulation, 2 days after ovulation and at the mid-luteal phase. Test days were determined by daily measurements of basal body temperature and were confirmed afterwards by determinations of serum luteinizing hormone, follicle-stimulating hormone, 17 beta-oestradiol and progesterone. 3. Peripheral skin circulation varied significantly within one menstrual cycle. The extremes were a mean finger skin temperature of 25.9 +/- 3.0 degrees C in the luteal phase compared with 28.4 +/- 3.7 degrees C in the pre-ovulatory phase (P = 0.002). The respective values for the mean laser Doppler flux were 18.4 +/- 10.9 compared with 29.2 +/- 16.4 arbitrary units (P = 0.003). 4. Baseline forearm muscle blood flow also varied significantly (P = 0.04) within one menstrual cycle, with low values in the menstrual phase compared with the other phases.(ABSTRACT TRUNCATED AT 250 WORDS)

    The variable infectivity and transmissibility of HIV/SHIV has been recently associated with the menstrual cycle, with particular susceptibility observed during the luteal phase in nonhuman primate models and ex vivo human explant cultures, but the mechanism is poorly understood. Here, we performed an unbiased, mass spectrometry-based proteomic analysis to better understand the mucosal immunological processes underpinning this observed susceptibility to HIV infection. Cervicovaginal lavage samples (n = 19) were collected, characterized as follicular or luteal phase using days since last menstrual period, and analyzed by tandem mass spectrometry. Biological insights from these data were gained using a spectrum of computational methods, including hierarchical clustering, pathway analysis, gene set enrichment analysis, and partial least-squares discriminant analysis with LASSO feature selection. Of the 384 proteins identified, 43 were differentially abundant between phases (P HIV. Recent studies have discovered an enhanced susceptibility to HIV infection during the progesterone-dominant luteal phase of the menstrual cycle. However, the mechanism responsible for this enhanced susceptibility has not yet been determined. Understanding the source of this vulnerability will be important for designing efficacious HIV prevention technologies for women. Furthermore, these findings may also be extrapolated to better understand the impact of exogenous hormone application, such as the use of hormonal contraceptives, on HIV acquisition risk. Hormonal contraceptives are the most widely used contraceptive method in sub-Saharan Africa, the most HIV-burdened area of the world. For this reason, research conducted to better understand how hormones impact host immunity and susceptibility factors important for HIV infection is a global health priority.

    Body fluids are a common and important type of forensic evidence. In particular, the identification of menstrual blood stains is often a key step during the investigation of rape cases. Here, we report on the application of near-infrared Raman microspectroscopy for differentiating menstrual blood from peripheral blood. We observed that the menstrual and peripheral blood samples have similar but distinct Raman spectra. Advanced statistical analysis of the multiple Raman spectra that were automatically (Raman mapping) acquired from the 40 dried blood stains (20 donors for each group) allowed us to build classification model with maximum (100%) sensitivity and specificity. We also demonstrated that despite certain common constituents, menstrual blood can be readily distinguished from vaginal fluid. All of the classification models were verified using cross-validation methods. The proposed method overcomes the problems associated with currently used biochemical methods, which are destructive, time consuming and expensive. Copyright © 2014 WILEY-VCH Verlag GmbH & Co.

    The goal of this work is to study the behavior of electromyographic variables during the menstrual cycle. Ten female volunteers (24.0 ± 2.8 years of age) performed fatiguing isometric contractions, and electromyographic signals were measured on the biceps brachii in four phases of the menstrual cycle. Adaptations of classical algorithms were used for the estimation of the root mean square (RMS) value, absolute rectified value (ARV), mean frequency (MNF), median frequency (MDF), and conduction velocity (CV). The CV estimator had a higher (p = 0.002) rate of decrease at the end of the follicular phase and at the end of the luteal phase. The MDF (p = 0.002) and MNF (p = 0.004) estimators had a higher rate of decrease at the beginning of the follicular phase and at the end of the luteal phase. No significant differences between phases of the menstrual cycle were detected with the ARV and RMS estimators (p > 0.05). These results suggest that the behavior of the muscles in women presents different characteristics during different phases of the menstrual cycle. In particular, women were more susceptible to fatigue at the end of the luteal phase

Transvaginal sonography (TVS is a popular tool for IUL detection, but there are conflicting data with respect to its accuracy.Methods: Five hundred and six women were enrolled into the study. Of these, 496 underwent hysterosalpingography and subsequent TVS six different times during the course of their menstrual cycle. If a lesion was detected, it was further evaluated by sonohysterography (SHG and hysteroscopy.Results: Of 496 women, 41 were shown to have IULs by TVS and those lesions were confirmed in 39 by SHG and hysteroscopy. All 39 lesions were detectable during the ovulatory and early luteal phase (days 16–19 of the menstrual cycle. Accuracy of TVS during different phases was largely dependent on the size of the lesion. TVS falsely detected two lesions and missed fine adhesions in two patients.Conclusion: Accuracy of TVS in detection of IULs is highly dependent on the menstrual cycle phase, with the ovulatory and early luteal phase being the optimal time for this examination.Keywords: menstrual cycle phase, space occupying lesions, transvaginal sonography

    Age and menstrual cycle have an important influence on the breast. This well-known fact is experienced in the daily routine of gynecologists and radiologists. The number of publications addressing the effect of these influences on imaging, however, is surprisingly low. The aim of this work is to describe the influences of age and menstrual cycle on the breast and to address their clinical relevance for mammography and MR mammography. Therefore, own data are presented concerning the age and menstrual cycle influences on breast parenchyma in dynamic MR mammography. Literature data are used to correlate mammography and MR imaging findings with these influences. The changes of the breast due to age and menstrual cycle have important direct implications on performing and reading conventional mammography and MR mammography. The knowledge of these changes is also helpful in the interpretation of findings when comparing different methods. Finally, the data gained by using imaging methods enable important basic insights into physiology and physiopathology of the breast in vivo. (orig.) [de

    Full Text Available Background: Menstruation is a physiological process in female adolescents which usually started at age of 9–12 years. Menstrual hygiene is a hygienic practice during menstruation which can prevent women from the infection in reproductive and urinary tract. Lack of knowledge regarding menstruation and menstrual hygiene lead to poor attitude and practice. This study was conducted to assess the level of knowledge, attitude and practice of menstrual hygiene among high schools students in Jatinangor. Methods: This descriptive cross-sectional study was conducted from May until June 2013 in high schools around Jatinangor. This study population was taken from four schools selected through cluster random sampling from 17 junior and senior high schools available in Jatinangor. Total sampling from four schools was undertaken and a total of 238 female high school students’ data were established. The respondents aged between 13–19 years old. Results: The level of knowledge, attitude and practice among participants were 180 (75.63%, 186 (78.15% and 210 (88.24% respectively which were mostly good. Conclusions: Overall, most of the participants in this study have good knowledge, attitude and practice about menstrual hygiene, but a few of them still have poor and moderate knowledge and attitude, although there is no poor practice among them.

    The objective of the present study was to investigate the relationship between ambivalent sexism and beliefs and attitudes towards menstruation, and, in turn, to study the influence of these variables on menstrual cycle-related symptoms. One hundred and six Mexican women completed the Ambivalent Sexism Inventory, the Beliefs about and Attitudes toward Menstruation Questionnaire and the Menstrual Distress Questionnaire. The higher scores on benevolent sexism were associated with the most positive attitudes towards menstruation and also with the belief that a menstruating woman should or should not do some activities and that menstruation keeps women from their daily activities. The higher scores on hostile sexism were associated with rejection of menstruation as well as with feelings of embarrassment about it. Beliefs about and attitudes towards menstruation predicted menstrual cycle-related symptoms related to negative affect, impaired concentration and behavioural changes, but did not predict somatic symptoms. These results will be useful to health professionals and advocates who want to change the negative expectations and stereotypes of premenstrual and menstrual women and reduce the sexism and negative attitudes towards women that are evident in Mexican culture. © 2013 International Union of Psychological Science.

    Magnetic resonance mammography (MRM) provides data regarding the nature of tumours based on contrast medium dynamics; fibrocystic changes in the breast, however, may lead to false-positive results. This study investigated whether the contrast medium dynamics of fibrocystic changes are dependent on the menstrual cycle. Twenty-four patients with palpable lumps but normal mammographies and ultrasound studies were examined. The MRM technique was performed during the first and second part of the menstrual cycle using a FLASH 3D sequence, both native and at 1, 2, 3 and 8 min after intravenous application of 0.15 mmol/kg body weight of gadodiamide. The calculated time-intensity curves were evaluated based on the following criteria: early percentage of contrast medium uptake in relation to the native value; formation of a plateau phenomenon after the second minute; the point of maximal contrast medium uptake; and calculation of the contrast enhancing index. During the second half of the menstrual cycle, a generally greater contrast medium uptake was observed. Nevertheless, when further diagnostic criteria, such as continuous contrast medium increase as a function of time, were considered, there was no increased rate of false-positive findings. The phase of the menstrual cycle may affect the specificity of the examination, if only the quantitative contrast medium uptake and the percentage of contrast medium uptake in the first 2 min are considered. A control MRM during the other half of the cycle may then be indicated and additional diagnostic criteria may improve specificity. (orig.)

  17. MENSTRUAL HYGIENE: GAPS IN THE KNOWLEDGE AND PRACTICES IN ADOLESCENT SCHOOL GIRLS

    Directory of Open Access Journals (Sweden)

    2015-04-01

    Full Text Available Menstrual hygiene is an issue that is insufficiently acknowledged. Menstruation and menstrual practices are still clouded by taboos and socio - cultural restrictions resulting in adolescent girls lacking knowledge and remaining ignorant of the scientific facts and hygienic health practices, which sometimes res ult into adverse health outcomes. Menstrual hygiene, a very important risk factor for reproductive tract infections (RTI, is a vital aspect of health education. Menarche is a significant milestone in the transitory developmental journey of an adolescent. Poor personal hygiene and defective menstrual management practices give rise to repeated reproductive tract infections (RTIs, which are otherwise preventable. Menstruation is generally considered as unclean in the Indian society. Isolation of the menstrua ting girls and restrictions being imposed on them in the family, have reinforced a negative attitude towards this phenomenon. There is a substantial lacuna in the knowledge about menstruation among adolescent. This study was conducted to assess the knowled ge, attitudes and practices of adolescent school girls of a secondary school in an urban setting. It was found that there was lack of knowledge in specific areas. This study throws light on lack of basic amenities in school for girls which in turn leads to unhygienic practices during menstruation. These reinforce the fact that health education has to be more effective and also that the need of the hour is basic amenities in schools.

    To investigate knowledge and beliefs about menstruation in the Tigray Region of Ethiopia. Between May 5 and May 25, 2015, a cross-sectional survey using semi-structured questionnaires was undertaken in 10 subdistricts (5 urban, 5 rural) in the Tigray Region of northern Ethiopia by trained data collectors (native speakers of the local languages). Individuals in randomly selected households who were aged 10years or older and who were willing to participate were asked various questions regarding the nature and management of menstruation. Interviews were recorded, and handwritten field notes were taken during the interview process. Data were compiled, transcribed, translated into English, categorized, and analyzed thematically. Overall, 428 household members (349 female, 79 male) were interviewed. Reproductive anatomy and biology of menstrual regulation were poorly understood by the respondents. The belief that menstruating girls should not attend school was voiced by 17 (21.5%) male and 37 (10.6%) female respondents. Satisfactory management of menstrual hygiene was acknowledged to be a problem, and many respondents complained about the high cost of commercially produced, disposable menstrual pads. Improved education on menstruation and better access to low-cost, reusable menstrual hygiene supplies would be worthwhile in the Tigray Region of Ethiopia.

    Many studies have reported that there are changes in sympathetic activity throughout the menstrual cycle as there are oestrogen receptor in the hypothalamus and all other parts of the sympathetic nervous system. The purpose of this study was to see whether there were variations in sympathetic activity, skin vasomotor and sweat gland sudomotor rhythms during the menstrual cycle. Eight young female subjects with a regular menstrual cycle participated in the study. Subjects were tested once during the follicular phase and once during the luteal phase. Skin blood flow and sweat rate were significantly higher in the luteal phase compared with the follicular phase (p < .05), but the frequency and magnitude of sudomotor and vasomotor rhythms were significantly greater in the follicular phase (p < .05). In contrast, spectral data showed less sympathetic activity in the luteal phase. A significant finding here is that the sudomotor rhythm of sweat glands is altered by the menstrual cycle. © 2015 Scandinavian Society of Clinical Physiology and Nuclear Medicine.

    Ongoing intrinsic brain activity in resting, but awake humans is dominated by alpha oscillations. In human, individual alpha frequency (IAF) is associated with cognitive performance. Noticeable, performance in cognitive and emotional tasks in women is associated with menstrual cycle phase and sex hormone levels, respectively. In the present study, we correlated frequency of alpha oscillation in resting women with menstrual cycle phase, sex hormone level, or use of oral contraceptives. Electroencephalogram (EEG) was recorded from 57 women (aged 24.07 ± 3.67 years) having a natural menstrual cycle as well as from 57 women (aged 22.37 ± 2.20 years) using oral contraceptives while they sat in an armchair with eyes closed. Alpha frequency was related to the menstrual cycle phase. Luteal women showed highest and late follicular women showed lowest IAF or center frequency. Furthermore, IAF as well as center frequency correlated negatively with endogenous estradiol level, but did not reveal an association with endogenous progesterone. Women using oral contraceptives showed an alpha frequency similar to women in the early follicular phase. We suggest that endogenous estradiol modulate resting alpha frequency.

    To evaluate the long-term effects on bone mineral density (BMD) in women diagnosed with menstrual disorders in their adolescence. Prospective follow-up study six years after the initial investigation. A youth clinic that is part of the school health system in Stockholm. Eighty-seven women diagnosed with secondary amenorrhea or oligomenorrhea in adolescence. Subjects underwent gynecological examination, evaluation of eating behavior and physical activity. Whole body Dual Energy X-ray Absorptiometry was used for measurement of BMD. BMD. The overall frequency of osteopenia/osteoporosis was 52%, and three girls had osteoporosis. Women with previous secondary amenorrhea had significantly lower BMD in the pelvis and lumbar spine than those with previous oligomenorrhea. The strongest predictor of low BMD was a restrictive eating disorder in adolescence and the most important counteraction was high physical activity at follow-up and a body mass index (BMI) > or = 22. Persistent menstrual dysfunction at follow-up was associated with polycystic ovary syndrome and lower frequency of osteopenia. This clinical follow-up study has demonstrated a high frequency of osteopenia in women diagnosed with menstrual disorders in adolescence. Previous anorectic behavior was the strongest negative predictor of BMD. It is important to pay attention to an underlying eating disorder in young women with menstrual dysfunction in order to promote bone health.

    Ankle and foot injuries are common among athletes and physically active individuals. The most common residual disability, ankle sprain, is characterized by instability along with postural sway. If the supporting structures around a joint become lax, posture stability and balance are also affected. Previous studies have examined muscle stiffness and elasticity and postural sway separately; however, the relationship between these factors is yet unknown. It is well known that the levels of sex hormones, especially estrogen, change in women over the phase of the menstrual cycle. Therefore, this study examined the relationship between the mechanical properties of tissue and balance activity using a non-invasive digital palpation device to determine if they undergo any changes over the menstrual cycle in young women. Sixteen young women with regular menstrual cycles completed the study. Tone, stiffness, and elasticity of the ankle muscles (lateral gastrocnemius, peroneus longus, and tibialis anterior) were measured using a non-invasive digital palpation device. Postural sway was recorded while the participants performed balance tasks during ovulation and menstruation. Significantly greater posture sway characteristics and ankle muscle elasticity were found during ovulation than during menstruation; lower tone and stiffness of the ankle muscles were observed at ovulation (p connective tissues. We therefore postulate that estrogen increases joint and muscle laxity and affects posture stability according to the phase of the menstrual cycle.

    Food intake is decreased during the late follicular phase and increased in the luteal phase of the menstrual cycle. While a changing ovarian steroid milieu is believed to be responsible for this behavior, the specific mechanisms involved are poorly understood. Brain activity in response to visual food stimuli was compared during the estrogen dominant peri-ovulatory phase and the progesterone dominant luteal phase of the menstrual cycle. Twelve women underwent functional magnetic resonance imaging during the peri-ovulatory and luteal phases of the menstrual cycle in a counterbalanced fashion. Whole brain T2* images were collected while subjects viewed pictures of high calorie (HC) foods, low calorie (LC) foods, and control (C) pictures presented in a block design. Blood oxygen level dependent (BOLD) signal in the late follicular phase and luteal phase was determined for the contrasts HC-C, LC-C, HC-LC, and LC-HC. Both HC and LC stimuli activated numerous corticolimbic brain regions in the follicular phase, whereas only HC stimuli were effective in the luteal phase. Activation of the nucleus accumbens (NAc), amygdala, and hippocampus in response to the HC-C contrast and the hippocampus in response to the LC-C contrast was significantly increased in the late follicular phase compared to the luteal phase. Activation of the orbitofrontal cortex and mid cingulum in response to the HC-LC contrast was greater during the luteal phase. These results demonstrate for the first time that brain responses to visual food cues are influenced by menstrual cycle phase. We postulate that ovarian steroid modulation of the corticolimbic brain contributes to changes in ingestive behavior during the menstrual cycle. Copyright © 2010 Elsevier B.V. All rights reserved.

    Menstrual cycle-related symptoms are an important health issue for many women, and some may affect cardiac autonomic regulation. In the present study, we evaluated the cardiovascular and physiological stress response to 12-h short-term fasting in the menstrual phases of healthy young women. We performed a randomized crossover study. Subjects were seven female university students (age: 22.3 ± 1.0 years). The experiments comprised four sessions: meal intake in the follicular phase, meal intake in the luteal phase, fasting in the follicular phase, and fasting in the luteal phase. All subjects participated in a total of four experimental sessions during two successive phases (follicular and luteal phase in the same menstrual cycle, or luteal phase and follicular phase in the next menstrual cycle) according to a randomized crossover design. R-R intervals were continuously recorded before and after meals, and power spectral analysis of heart rate variability was performed. Other physiological data were obtained before and 20, 40, 60, and 80 min after meal intake or after the corresponding time point of meal intake (fasting in the follicular or luteal phase). Heart rate decreased during fasting in the follicular and luteal phases. High frequency power increased during fasting in the follicular and luteal phases. In addition, salivary cortisol concentrations decreased during fasting in the luteal phase. In the present study, short-term fasting resulted in higher parasympathetic activity and lower cortisol levels in the luteal phase in these young women. These results indicate a possibility to produce an anti-stress effect in the luteal phase, which may reduce menstrual symptoms.

    Management of menstruation in contexts of humanitarian emergencies can be challenging. A lack of empirical research about effective interventions which improve menstrual hygiene management (MHM) among female populations in humanitarian emergencies and a lack of clarity about which sectors within a humanitarian response should deliver MHM interventions can both be attributable to the lack of clear guidance on design and delivery of culturally appropriate MHM intervention in settings of humanitarian emergencies. The objective of this review was to collate, summarize, and appraise existing peer-reviewed and gray literature that describes the current scenario of MHM in emergency contexts in order to describe the breadth and depth of current policies, guidelines, empirical research, and humanitarian aid activities addressing populations' menstrual needs. A structured-search strategy was conducted for peer-reviewed and gray literature to identify studies, published reports, guidelines, and policy papers related to menstrual response in emergency humanitarian contexts. Of the 51 articles included in the review, 16 were peer-reviewed papers and 35 were gray literature. Most of the literature agreed that hardware interventions should focus on the supply of adequate material (not only absorbent material but also other supportive material) and adequate sanitation facilities, with access to water and private space for washing, changing, drying, and disposing menstrual materials. Software interventions should focus on education in the usage of materials to manage menstruation hygienically and education about the female body's biological processes. There was clear agreement that the needs of the target population should be assessed before designing any intervention. Although there is insight about which factors should be included in an effective menstrual hygiene intervention, there is insufficient empirical evidence to establish which interventions are most effective in

  14. Progesterone mediates brain functional connectivity changes during the menstrual cycle - A pilot resting state MRI study

    2015-02-01

    Full Text Available The growing interest in intrinsic brain organization has sparked various innovative approaches to generating comprehensive connectivity-based maps of the human brain. Prior reports point to a sexual dimorphism of the structural and functional human connectome. However, it is uncertain whether subtle changes in sex hormones, as occur during the monthly menstrual cycle, substantially impact the functional architecture of the female brain. Here, we performed eigenvector centrality (EC mapping in 32 longitudinal resting state fMRI scans of a single healthy subject without oral contraceptive use, across four menstrual cycles, and assessed estrogen and progesterone levels. To investigate associations between cycle-dependent hormones and brain connectivity, we performed correlation analyses between the EC maps and the respective hormone levels. On the whole brain level, we found a significant positive correlation between progesterone and EC in the bilateral DLPFC and bilateral sensorimotor cortex. In a secondary region-of-interest analysis, we detected a progesterone-modulated increase in functional connectivity of both bilateral DLPFC and bilateral sensorimotor cortex with the hippocampus. Our results suggest that the menstrual cycle substantially impacts intrinsic functional connectivity, particularly in brain areas associated with contextual memory-regulation, such as the hippocampus. These findings are the first to link the subtle hormonal fluctuations that occur during the menstrual cycle, to significant changes in regional functional connectivity in the hippocampus in a longitudinal design, given the limitation of data acquisition in a single subject. Our study demonstrates the feasibility of such a longitudinal rs-fMRI design and illustrates a means of creating a personalized map of the human brain by integrating potential mediators of brain states, such as menstrual cycle phase.

    In 2016, a large meta-analysis brought the number of susceptibility loci for migraine to 38. While sub-type analysis for migraine without aura (MO) and migraine with aura (MA) found some loci showed specificity to MO, the study did not test the loci with respect to other subtypes of migraine. This study aimed to test the hypothesis that single nucleotide polymorphisms (SNPs) robustly associated with migraine are individually or collectively associated with menstrual migraine (MM). Genotyping of migraine susceptibility SNPs was conducted using the Agena MassARRAY platform on DNA samples from 235 women diagnosed with menstrual migraine as per International Classification for Headache Disorders II (ICHD-II) criteria and 140 controls. Alternative genotyping methods including restriction fragment length polymorphism, pyrosequencing and Sanger sequencing were used for validation. Statistical analysis was performed using PLINK and SPSS. Genotypes of 34 SNPs were obtained and investigated for their potential association with menstrual migraine. Of these SNPs, rs2506142 located near the neuropilin 1 gene (NRP1), was found to be significantly associated with menstrual migraine (p = 0.003). Genomic risk scores were calculated for all 34 SNPs as well as a subset of 7 SNPs that were nearing individual significance. Overall, this analysis suggested these SNPs to be weakly predictive of MM, but of no prognostic or diagnostic value. Our results suggest that NRP1 may be important in the etiology of MM. It also suggests some genetic commonality between common migraine subtypes (MA and MO) and MM. The identification of associated SNPs may be the starting point to a better understanding of how genetic factors may contribute to the menstrual migraine sub-type.

    Full Text Available Introduction: The rate of anterior cruciate ligament (ACL tearing is more common in female athletes and one of thereasons is the effect of sex hormones. It was illustrated that knee joint position sense (JPS isaltered across the menstrual cycle and its lowest level is at menses. Therefore, it’s important to find a method to reduce injury risk at menses. Thus, the purpose of this study was to evaluate the effect of taping as a stimulator of skin, on the knee JPS in healthy female athletes across the menstrual cycle with different levels of estrogen and progesterone. Materials and Methods: In this semi-experimental study, 16 healthy female athletes with regular menstrual cycle voluntarily participated. Knee JPS was measured at 3 menstrual cycle phases, before and after patellataping. JPS was evaluated by reproduction of the target angle (30° flexion in standing position, from full extension. Serum estrogen and progesterone levels were collected in these 3 phases. Knee angles were measured by using a system comprised of skin markers, digital photography, and autoCAD software. Absolute error was considered as a dependent variable.Results: There was a significant difference between the knee JPS in 3 phases of measurement before taping (P=0.025, while no significant difference was found between knee JPS in 3 phases after taping (P=0.965. Conclusion: Findings of this study suggest that healthy female athletes have different levels of knee JPS across a menstrual cycle and its accuracy decreasesat menses. This differencecan be reduced by skin stimulatingmethods, such as taping. Therefore, kinesio taping would improve the knee JPSdeficiency at menses.

To evaluate the risk of lower genital tract infections (LGTIs and menstrual abnormalities following interval laparoscopic sterilisation.Methods. A prospective cohort study of 225 women undergoing sterilisation between August 2012 and April 2013, with follow-up 1 year post procedure, was conducted at King Dinuzulu Hospital, Durban.Results. Following sterilisation, LGTIs were increased only in women with a history of infection pre sterilisation (odds ratio 6.7; 95% CI 2.2 - 20.9; p=0.002. There was no significant risk of HIV acquisition post sterilisation. In women who had not used contraception or used barrier methods pre sterilisation, we found no significant change in menstrual patterns post sterilisation. There was an increase in menstrual bleeding and dysmenorrhoea post sterilisation among previous combined oral contraceptive users. Among women with amenorrhoea on injectable contraception pre sterilisation, 73.8% reported return to regular menses and 26.2% reported abnormal uterine bleeding post sterilisation. Among injectable contraceptive users with regular menses pre sterilisation, 71.4% reported no change in menses post sterilisation and 28.6% reported abnormal uterine bleeding post sterilisation.Conclusion. In women undergoing interval tubal sterilisation, the risk of LGTIs was only increased in those women with a history. Menstrual abnormalities post sterilisation were more likely in women who used steroid contraception prior to sterilisation.

    Full Text Available Dysmenorrhea or pain during menstruation is the most common gynaecological complaint among adolescents and college students. A good majority of patients with dysmenorrhea also experience pre - menstrual symptoms ( PMS . The objective of this cross s ectional study was to assess prevalence of dysmennorhea , PMS , college absenteeism and knowledge attitudes and practices relating to the same among college going students between the age of 18 to 26 years. METHODS: A cross s ectional analysis of a total of 420 students using questionnaires related to dysmenorrhea was done . The questionnaire dealt with the regularity of menstrual cycles , occurrence of dysmenorrhea , college absenteeism , premenstrual symptoms and lifestyle attributes of the students. RESULTS: The prevalence of dysmenorrhea of varying degrees was found to be as high as 97 percent . Dysmennorhea was seen in 45.8 percent of students with regular cycles and 97.7 percent of students with irregular cycles. 47.5 percentage of students missed their college working days due to menstruation related complaints. Among the students who had pre - menstrual syndrome , majority of them revealed life style attributes like eating fast food and also consuming over the counter pain medicines. Also psychological and emotional changes were commonly seen during the premenstrual phase. CONCLUSION: This study showed that though dysmennorhea of varying degrees is widely prevalent among college going students , the prevalence of pre - menstrual syndrome was higher. The study suggests that adequate counseling and education about menstrual symptoms and abuse of OTC analgesics if made a part of college curriculum as well as lifestyle modifications could come a long way in helping to alleviate the problems college students face due to dysmennorhea and PMS.

    The onset of menstruation is one of the most important physiological changes occurring among girls during the adolescent years. Menstruation heralds the onset of physiological maturity in girls. It becomes the part and parcel of their lives until menopause. Apart from personal importance, this phenomenon also has social significance. In India, menstruation is surrounded by myths and misconceptions with a long list of "do's" and "don'ts" for women. Hygiene-related practices of women during menstruation are of considerable importance, as it may increase vulnerability to Reproductive Tract Infections (RTI's). Poor menstrual hygiene is one of the major reasons for the high prevalence of RTIs in the country and contributes significantly to female morbidity. Most of the adolescent girls in villages use rags and old clothes during menstruation, increasing susceptibility to RTI's. Adolescents constitute one-fifths of India's population and yet their sexual health needs remain largely unaddressed in the national welfare programs. Poor menstrual hygiene in developing countries has been an insufficiently acknowledged problem. In June 2010, the Government of India proposed a new scheme towards menstrual hygiene by a provision of subsidized sanitary napkins to rural adolescent girls. But there are various other issues like awareness, availability and quality of napkins, regular supply, privacy, water supply, disposal of napkins, reproductive health education and family support which needs simultaneous attention for promotion of menstrual hygiene. The current article looks at the issue of menstrual hygiene not only from the health point of view, but also considers social and human rights values attached to it.

    Objective: To determine the frequency of Von Willebrand disease (vWD) in patients of heavy menstrual bleeding (HMB). Study Design: Hospital based cross sectional study. Place and Duration of Study: Study was conducted at the Gynecology and Obstetrics department, Military Hospital, Rawalpindi in collaboration with Haematology Department of Armed Forces Institute of Pathology (AFIP) Rawalpindi, from Jul to Dec 2015. Material and Methods: Women presenting with HMB were enrolled in the study after informed consent. HMB was defined as cyclical bleeding at normal intervals but patient is using more than 5 pads per day or increase in duration 8/28 or more for at least last 06 months. Venous blood samples were taken and screened for the hemoglobin level (Hb), platelet count, prothrombin time (PT), activated partial thromboplastin time (aPTT) and Von Willebrand antigen (vWF:Ag) in addition to bleeding time (BT) at the Armed Forces Institute of Pathology (AFIP). The demographic details (age, age at menarche), clinical features (menstrual history, quantity of bleeding) and laboratory findings were recorded on the study proforma. Results: A total of 200 patients were enrolled in this study with mean age of 32.3 +- 8.5 years. Mean flow of menstrual blood was 9.8 +- 2.5 pads / day. Mean Hb percent was 8.1 +- 1.4 g/dl. Twenty nine (14.5 percent) patients were having low level of vWF:Ag. Conclusion: There is high frequency of von Willebrand disease among females presenting with heavy menstrual bleeding in our set up. Therefore all patients with heavy menstrual bleeding except those with obvious causes like multiple fibroid should be screened for von Willebrand disease. (author)

    Sports medicine professionals commonly describe two functionally different units of the vastus medialis (VM), the VM, and the vastus medialis oblique (VMO), but the anatomical support is equivocal. The functional difference of the VMO is principle to rehabilitation programs designed to alleviate anterior knee pain, a pathology that is known to have a greater occurrence in women. The purpose of this study was to determine whether the motor units of the VM and VMO are differentially recruited and if this recruitment pattern has an effect of sex or menstrual cycle phase. Single motor unit recordings from the VM and VMO were obtained for men and women during an isometric ramp knee extension. Eleven men were tested once. Seven women were tested during five different phases of the menstrual cycle, determined by basal body temperature mapping. The recruitment threshold and the initial firing rate at recruitment were determined from 510 motor unit recordings. The initial firing rate was lower in the VMO than that in the VM in women (P recruitment thresholds for the VM and VMO in either sex or across the menstrual cycle. There was a main effect of menstrual phase on initial firing rate, showing increases from the early follicular to late luteal phase (P = 0.003). The initial firing rate in the VMO was lower than that in the VM during ovulatory (P = 0.009) and midluteal (P = 0.009) phases. The relative control of the VM and VMO changes across the menstrual cycle. This could influence patellar pathologies that have a higher incidence in women.

    An increased incidence of sports related injuries in the premenstrual phase as well as in the menstrual phase of the menstrual cycle has been described. This may be explained by alterations in proprioception and neuromuscular coordination due to hormonal variations. Prospective, within women analysis of knee joint kinesthesia and neuromuscular coordination were performed by repeated measures analysis of variance in three hormonally verified phases of three consecutive menstrual cycles. Thirty-two healthy, moderately active female subjects volunteered to participate in the study. Twenty-five of the subjects performed at least one hormonally verified menstrual cycle. A specially designed device was used to investigate knee joint kinaesthesia and neuromuscular coordination was measured with the square hop test. These tests were carried out in the menstrual phase, ovulation phase and premenstrual phase determined by hormone analyses in three consecutive menstrual cycles. An impaired knee joint kinaesthesia was detected in the premenstrual phase and the performance of square hop test was significantly improved in the ovulation phase compared to the other two phases. The results of this study indicate that the variation of sex hormones in the menstrual cycle has an effect on performance of knee joint kinaesthesia and neuromuscular coordination.

    Folk culture surrounding menstrual-related matters has considerable implications for symptom expression and treatment-seeking behavior. A cross-sectional survey of 1,295 rural adolescent girls aged 13 to 19 years was conducted between February 4 and April 16, 2009 to examine these associations. With a higher score indicating a more positive attitude toward menstruation, the mean attitude score was 3.84 (SD ± 1.62) out of a maximum of six. No significant association was observed between the severity of menstrual symptoms and attitudes. Most (63.1%) of the participants identified themselves as having premenstrual symptoms, and 61.1% viewed premenstrual symptoms as a normal part of menstrual cycle. Participants with a higher severity of symptoms in the premenstrual (OR 1.05, 95% CI 1.01-1.10) and menstrual phase (OR 1.04, 95% CI 1.01-1.07), were more likely to consult a physician for premenstrual symptoms, and having a divorced/separated parents was associated with a reduced odds of consulting a physician compared to those having parents that were married (OR 0.19, 95% CI 0.05-0.83). The findings imply the need for education to help adolescent girls manage menstrual symptoms and increase awareness of the benefit of treating them. Given that menstrual-related information was widely available from mothers, family, and social culture are potentially important in shaping good menstrual attitudes.

    To assess the impact of a school-based menstrual education programme on: (1) menstrual knowledge, beliefs and practices, (2) menstrual disorders experienced, and (3) restrictions on menstruating adolescents. Intervention study. Araihazar area, Bangladesh. 416 adolescent female students aged 11-16 years, in grade 6-8, and living with their parents. A school-based health education study conducted from April 2012 to April 2013. We randomly selected 3 of 26 high schools in the study area. We delivered 6 months of educational intervention by trained (by an obstetrician and gynaecologist) research assistants (RAs) on menstrual hygiene among school girls. RAs read the questionnaire and participants answered. The changes in knowledge, beliefs and practices regarding menstruation, menstrual disorders experienced, and the restrictions and behaviours practiced by menstruating adolescents were compared between the baseline and the follow-up assessments. After health education, participants reported a significant improvement (pmenstruation (78.6% vs 59.6%). The programme produced significant changes in the knowledge, beliefs and practices of menstrual hygiene, complications from lack of hygiene, and the behaviour and restrictions of the menstruating adolescents. These results demonstrate the feasibility of implementing a health education programme for adolescents on menstrual hygiene in secondary schools serving rural Bangladesh.

    It is well known that women are physiologically and psychologically influenced by the menstrual cycle. In addition, the presence of background noise may affect task performance. So far, it has proven difficult to describe how the menstrual cycle and background noise affect task performance; some researchers have found an increment of performance during menstruation or during the presence of noise, others found performance deterioration, while other still have reported no dominant effect either of the menstrual cycle in performance or of the presence of noise. However, no study to date has investigated the combinational effect between the menstrual cycle and the presence of background noise in task performance. Therefore, the purpose of this study was to examine the combined factor effect of menstrual cycle and background noise on visual inspection task performance indices by Signal Detection Theory (SDT) metrics: sensitivity index (d') and response criteria index (beta). For this purpose, ten healthy female students (21.5+/-1.08 years) with a regular menstrual cycle participated in this study. A VDT-based visual inspection task was used for the experiment in 3x2 factorial designs. Two factors, menstrual phase, pre-menstruation (PMS), menstruation (M), and post-menstruation (PM) and background noise, with 80 dB(A) background noise and without noise, were analyzed as the main factors in this study. The results concluded that the sensitivity index (d') of SDT was affected in all the menstrual cycle conditions (pbackground noise (pbackground noise was found in this study. On the other hand, no significant effect was observed in the subject's tendency in visual inspection, shown by beta along the menstrual cycle and the presence of background noise. According to the response criteria for each individual subject, the presence of noise affected the tendency of some subjects in detecting the object and making decision during the visual inspection task.

    There have been several studies evaluating the association between vitamin and mineral status and menstrual disturbance. In the present study, we aimed to assess the relationship between the menstrual bleeding pattern and premenstrual syndrome (PMS) symptoms with serum 25-hydroxyvitamin D, and calcium levels in adolescent girls. A cross-sectional study was carried out in 897 high school girls from northeastern Iran. The prevalence of hypocalcaemia, normal serum calcium and hypercalcaemia was 27.1, 59.8 and 13.1%, respectively. The menstrual flow of participants differed significantly between the calcium status groups (p = .005). There was no significant association between the symptoms of PMS, as assessed by the questionnaire and serum vitamin D status, or serum calcium concentrations, apart from the irritability. There appears to be an association between serum calcium, menstrual blood loss and irritability in adolescent girls. Impact statement What is already known on this subject? Several studies have evaluated the association of vitamin and mineral status with menstrual disturbance, although these relationships are not consistent, specifically among calcium and vitamin D levels with a menstrual bleeding pattern. What do the results of this study add? In the present study, we investigated the correlation of menstrual bleeding patterns and PMS with calcium and vitamin D levels in a large population in adolescent girls. We found that the level of calcium was associated with the level of menstrual blood loss and irritability. However, no significant association was observed between the menstrual bleeding pattern or the PMS symptoms with a vitamin D status. What are the implications of these findings for future clinical practise/research? Further studies are required to assess the value of a calcium adequate intake or a calcium supplementation for the amelioration of PMS and a better understanding the role of calcium in PMS.

    Full Text Available Background: Disturbances of menstrual bleeding are major social and medical problem for women and account for high percentage of gynecological visit. Objectives: The objective of the study was to document menstrual abnormalities experienced by female college students, their awareness and health seeking behavior. Materials and Methods: A cross-sectional survey was undertaken, 400 students were selected using stratified sampling technique and interviewed using semi-structured self-administered questionnaire. Inferential statistical analysis such as Chi-square test and logistic regressions were carried out. Results: The mean age at menarche was 14.18 years. Irregular menstrual cycles were reported in 9.0%. Dysmenorrhea was present in 62.5%, and 12.5% reported school absenteeism. Students′ awareness of menstrual abnormalities was poor (29%. A few of them (10.5% decided to seek help for menstrual abnormalities. The awareness of students on menstrual abnormalities was significantly influenced by their age (OR = 2.33, P = 0.03; however, age at menarche and level of study did not influence their awareness (OR = 0.45, P = 0.24 and OR = 1.42, P = 0.12. History of dysmenorrheal (OR = 10.2, P = 0.001 and academic disturbance (OR = 5.45, P = 0.001 had significant influence on the health seeking behavior of the students. Conclusion: There was a general lack of information about menstrual issues and when to seek help. There is a need to educate female college students about menstrual issues in order to improve their health seeking behavior as regards menstrual abnormalities.

    Full Text Available Background The World Health Organization (WHO has defined adolescence as the age group of 10-19 years. Adolescents in India comprise 19.3% of the total Indian population. Adolescence is a transition phase through which a child becomes an adult. It is characterized by rapid growth and development; physiologically, psychologically and socially. This period is marked by the onset of menarche. Menstruation is a natural, normal biological process experienced by all adolescent girls and women in reproductive age. Objectives To study the menstrual pattern and prevalence of dysmenorrhea among school going adolescent girls in a rural block of Haryana. Methods There were 18 government high and senior secondary schools in block Lakhanmajra. Out of these 5 were exclusively girls’ schools, 10 were co-ed schools and 3 were exclusively boys’ schools. All the 5 schools meant exclusively for girls were included in the study. All girls studying in 6th to 12th classes from these schools, after applying the exclusion criteria were included in the study. Results The mean age at menarche was 12.83±1.326 years. The inter-menstrual interval was 21 to 35 days in majority (80.1% of the adolescent girls and the duration of menstruation was more than 7 days in 9.4% of the girls. Majority of the girls (52.1% reported the duration of menstruation to be 2-3 days.

    Reproductive hormones are likely to be involved in thermoregulation through body fluid dynamics. In the present study, we aimed to investigate the effect of the menstrual cycle and water consumption on physiological responses to prolonged exercise at moderate intensity in hot conditions. Eight healthy young women with regular menstrual cycles performed cycling exercise for 90 minutes at 50% V̇O2peak intensity during the low progesterone (LP) level phase and high progesterone (HP) level phase, with or without water consumption, under hot conditions (30°C, 50% relative humidity). For the water consumption trials, subjects ingested water equivalent to the loss in body weight that occurred in the earlier non-consumption trial. For all four trials, rectal temperature, cardiorespiratory responses, and ratings of perceived exertion (RPE) were measured. Throughout the 90-minute exercise period, rectal temperatures during HP were higher than during LP by an average of 0.4 °C in the non-consumption trial (Pwater consumption trial (Pwater consumption affected the changes in rectal temperature and heat rate (HR) during HP, but it did not exert these effects during LP. Furthermore, we found a negative correlation between estradiol levels and rectal temperature during LP. During prolonged exercise at moderate intensity under hot conditions, water consumption is likely to be useful for suppressing the associated increase in body temperature and HR, particularly during HP, whereas estradiol appears to be useful for suppressing the increase in rectal temperature during LP.

    Full Text Available Crystal VanLeeuwen, Belen Torondel Department of Disease Control, London School of Hygiene and Tropical Medicine, London, UK Abstract: Management of menstruation in contexts of humanitarian emergencies can be challenging. A lack of empirical research about effective interventions which improve menstrual hygiene management (MHM among female populations in humanitarian emergencies and a lack of clarity about which sectors within a humanitarian response should deliver MHM interventions can both be attributable to the lack of clear guidance on design and delivery of culturally appropriate MHM intervention in settings of humanitarian emergencies. The objective of this review was to collate, summarize, and appraise existing peer-reviewed and gray literature that describes the current scenario of MHM in emergency contexts in order to describe the breadth and depth of current policies, guidelines, empirical research, and humanitarian aid activities addressing populations’ menstrual needs. A structured-search strategy was conducted for peer-reviewed and gray literature to identify studies, published reports, guidelines, and policy papers related to menstrual response in emergency humanitarian contexts. Of the 51 articles included in the review, 16 were peer-reviewed papers and 35 were gray literature. Most of the literature agreed that hardware interventions should focus on the supply of adequate material (not only absorbent material but also other supportive material and adequate sanitation facilities, with access to water and private space for washing, changing, drying, and disposing menstrual materials. Software interventions should focus on education in the usage of materials to manage menstruation hygienically and education about the female body’s biological processes. There was clear agreement that the needs of the target population should be assessed before designing any intervention. Although there is insight about which factors should be

    This study evaluated the effect of menstruation on psychiatric hospitalization. We conducted a retrospective chart review of the medical records of 177 women who met the eligibility criteria. Data collected included demographic details, primary and secondary diagnoses, date of last menstrual period (LMP), medication adherence, psychiatric hospitalization length of stay, previous psychiatric admissions (including those related to menstruation), discharge referrals, and readmissions. The majority of women were admitted for major depression, were single, Caucasian, and had a mean age of 34. A disproportionate percentage (37%) of women had their LMP within 5 days of psychiatric hospitalization (p = 0.0006). The overall average length of stay was 4.37 days, and 48.3% had a previous psychiatric admission. Medication adherence was routinely not documented (77.4%). Psychiatric hospitalizations for women are significantly greater within 5 days of their LMP. Nursing education and improved documentation are warranted to decrease the potential for readmission.

    Objectives To assess the status of menstrual hygiene management (MHM) among adolescent girls in India to determine unmet needs. Design Systematic review and meta-analysis. We searched PubMed, The Global Health Database, Google Scholar and references for studies published from 2000 to September 2015 on girls’ MHM. Setting India. Participants Adolescent girls. Outcome measures Information on menarche awareness, type of absorbent used, disposal, hygiene, restrictions and school absenteeism was extracted from eligible materials; a quality score was applied. Meta-analysis was used to estimate pooled prevalence (PP), and meta-regression to examine the effect of setting, region and time. Results Data from 138 studies involving 193 subpopulations and 97 070 girls were extracted. In 88 studies, half of the girls reported being informed prior to menarche (PP 48%, 95% CI 43% to 53%, I2 98.6%). Commercial pad use was more common among urban (PP 67%, 57% to 76%, I2 99.3%, n=38) than rural girls (PP 32%, 25% to 38%, I2 98.6%, n=56, pMenstruating girls experienced many restrictions, especially for religious activities (PP 0.77, 0.71 to 0.83, I2 99.1%, n=67). A quarter (PP 24%, 19% to 30%, I2 98.5%, n=64) reported missing school during periods. A lower prevalence of absenteeism was associated with higher commercial pad use in univariate (p=0.023) but not in multivariate analysis when adjusted for region (p=0.232, n=53). Approximately a third of girls changed their absorbents in school facilities (PP 37%, 29% to 46%, I2 97.8%, n=17). Half of the girls’ homes had a toilet (PP 51%, 36% to 67%, I2 99.4%, n=21). The quality of studies imposed limitations on analyses and the interpretation of results (mean score 3 on a scale of 0–7). Conclusions Strengthening of MHM programmes in India is needed. Education on awareness, access to hygienic absorbents and disposal of MHM items need to be addressed. Trial registration number CRD42015019197. PMID:26936906

    Conclusion: Female adult rats with 9-week continuous exercise can cause menstrual dysregulation as a model for EAMD. Post-EAMD intervention with glucose and oligosaccharide intake can normalize the menstrual cycle, restore the follicular subcellular structure, and reverse the exercise-induced reduction of ovary sex hormones. It suggests a positive feedback of hypothalamus–pituitary–ovary axis might be involved in the molecular mechanisms of energy intake in treating EAMD.

    Menstrual irregularity is an indicator of endocrine disorders and reproductive health status. It is associated with various diseases and medical conditions, including obesity and underweight. We aimed to assess the association between body weight changes and menstrual irregularity in Korean women. A total of 4,621 women 19 to 54 years of age who participated in the 2010 to 2012 Korea National Health and Nutrition Examination Survey were included in this study. Self-reported questionnaires were used to collect medical information assessing menstrual health status and body weight changes. Odds ratios (ORs) and 95% confidence interval (CI) were calculated to evaluate the association between body weight changes and menstrual irregularity. Significantly higher ORs (95% CI) were observed in the association between menstrual irregularity and both weight loss (OR, 1.74; 95% CI, 1.22 to 2.48) and weight gain (OR, 1.45; 95% CI, 1.13 to 1.86) after adjusting for age, body mass index, current smoking, heavy alcohol drinking, regular exercise, calorie intake, education, income, metabolic syndrome, age of menarche, parity, and stress perception. Of note, significant associations were only observed in subjects with obesity and abdominal obesity, but not in non-obese or non-abdominally obese subjects. U-shaped patterns were demonstrated in both obese and abdominally obese subjects, indicating that greater changes in body weight are associated with higher odds of menstrual irregularity. We found a U-shaped pattern of association between body weight changes and menstrual irregularity among obese women in the general Korean population. This result indicates that not only proper weight management but also changes in body weight may influence the regulation of the menstrual cycle. Copyright © 2017 Korean Endocrine Society

    Menstrual low back pain (LBP) in young females can reduce daily activity and cause functional disability, while the progressive application of kinesio-taping (KT) on pain reduction and functional correction has been stated. This study has been designed to investigate the efficacy of the lumbar vertebral column KT in young female with menstrual LBP. Thirty-two young females with menstrual LBP participated in this crossover study and were assigned randomly in two separate groups. The first group received KT during their first menstrual cycle and No-KT in their next menstrual, while the other group had no KT during the first mentrual cycle and received KT during the next menstrual cycle. The primary outcome measurements included the visual analogue scale (VAS) of pain, Oswestry disability index and McGill pain questionnaire score which were planned to collect at the end of the third day of the menstrual cycle. Comparing pain and disability between two conditions, of menstrual cycle with KT and menstrual cycle without KT, revealed significant reduction in VAS (mean change = 1.7; 95%CI = 0.6 to 2.8; P= 0.005), McGill pain score (mean change = 20.1; 95%CI = 8.7 to 31.3; P= 0.001) and functional disability (mean change = 12.3; 95%CI = 7.2 to 17.5; Pkinesiotaping in young females with menstrual LBP.

    A vesicouterine fistula is a rare form of urogenital fistula, yet there is increasing prevalence in the United States because of the rising rate of cesarean deliveries. Vesicouterine fistulas have various presentations including menouria, hematuria, or urinary incontinence. A 39-year-old multiparous woman presented with urine leakage after her third cesarean delivery. She had been treated for mixed urinary incontinence with overactive bladder medications and a midurethral sling with continued complaints of urine leakage. The patient noticed her symptoms of urine leakage improved during menses when she used a menstrual cup. After confirmation of vesicouterine fistula, the patient underwent robotic-assisted surgery and her symptoms of insensible urine leakage resolved. When evaluating women with urinary incontinence and a history of cesarean deliveries, use of menstrual cup may aid in the diagnosis of vesicouterine fistula. Robotic-assisted laparoscopic repair with tissue interposition flap is an efficacious minimally invasive method for treatment of vesicouterine fistula.

    Patterns of eating, exercise, sleep, and health were investigated across 180 menstrual cycles of 89 women who engaged in sex with a male (n = 45; cycles = 85), a female (n = 21; cycles = 37), or abstained from sex (n = 33; cycles = 58) from January 2005 to December 2007 (10 contributed to 2 groups). Cycles were divided into 5 phases based on their luteinizing hormone surges. Daily questionnaires and saliva for IgA and cortisol analyses were obtained. Women indicated that they ate more (p Sexually active women had lower cortisol and IgA levels than abstinent women (p = .02). Our study discovered, and confirmed, systematic differences in eating, sleeping, and health patterns across women's menstrual cycles.

    The binding of 125 I-labeled human luteinizing hormone (hLH) to the 2000-g fraction of human ovarian follicles and corpora lutea during the entire menstrual cycle was examined. Specific high affinity, low capacity receptors for hLH were demonstrated in the 2000-g fraction of both follicles and corpora lutea. Specific binding of 125 I-labeled hLH to follicular tissue increased from the early follicular phase to the ovulatory phase. Specific binding of 125 I-labeled hLH to luteal tissue increased from the early luteal phase to the midluteal phase and decreased towards the late luteal phase. The results of the present study indicate that the increase and decrease in receptors for hLH during the menstrual cycle might play an important role in the regulation of the ovarian cycle

    This study aimed to examine the effectiveness of a modified stretching exercise program on young women with menstrual low back pain. Overall, 127 young women were randomly assigned to the experimental ( n = 63) and control ( n = 64) groups. The experimental group followed the modified stretching exercise program, whereas the control group performed their usual activities. At 1, 4, 8, and 12 months, the experimental group had significantly lower scores on the visual analog scale for pain (95% confidence interval [CI] = [0.73, 1.96]; p < .05) and the Oswestry Low Back Pain Disability Questionnaire than the control group (95% CI = [0.68, 2.03]; p < .001). At 12 months, the experimental group showed significantly higher exercise self-efficacy than the control group (95% CI = [-6.87, 0.62]; p = .003). These findings can be used to enhance self-care capabilities by using the modified stretching exercise program for young women with menstrual low back pain.

    Full Text Available Leptin, a circulating 16-kd polypeptide consisting of 167 amino acids, appears to be involved in the body weight homeostasis. Moreover leptin plays an important role for the reproductive system, early embryogenesis, and fat metabolism during pregnancy and puberty. Significant correlations have been found between leptin and sexual hormones, which is a cytokine and has hormonal properties. The aim of this study was to determine serum leptin levels during the menstrual cycle, and the association between serum leptin and reproductive hormones in young, healthy Iranian women. 42 healthy women volunteered for the study. They all had regular menstrual cycles, with cycle length varying between 26 and 32 days. None of them used oral contraceptives. All were of normal weight, with body mass index ( BMI

    The Military Women's Attitudes Toward Menstrual Suppression scale (MWATMS) was created to measure attitudes toward menstrual suppression during deployment. The human health and social ecology theories were integrated to conceptualize an instrument that accounts for military-unique aspects of the environment on attitudes toward suppression. A three-step instrument development process was followed to develop the MWATMS. The instrument was pilot tested on a convenience sample of 206 military women with deployment experience. Reliability was tested with measures of internal consistency (alpha = .97); validity was tested with principal components analysis with varimax rotation. Four components accounted for 65% of variance: Benefits/Interest, Hygiene, Convenience, and Soldier/Stress. The pilot test of the MWATMS supported its reliability and validity. Further testing is warranted for validation of this instrument.

    Spontaneous intrusive recollections (SIRs) are known to follow emotional events in clinical and non-clinical populations. Previous work in our lab has found that women report more SIRs than men after exposure to emotional films, and that this effect is driven entirely by women in the luteal phase of the menstrual cycle. To replicate and extend this finding, participants viewed emotional films, provided saliva samples for sex hormone concentration analysis, and estimated SIR frequency following film viewing. Women in the luteal phase reported significantly more SIRs than did women in the follicular phase, and SIR frequency significantly correlated with salivary progesterone levels. The results are consistent with an emerging pattern in the literature suggesting that menstrual cycle position of female participants can potently influence findings in numerous cognitive domains. The potential implications of these results for disorders characterized by intrusions, such as post-traumatic stress disorder, are also discussed. Copyright © 2011 Elsevier Inc. All rights reserved.

    This study examined the knowledge and practices of adolescent school girls in Kano, Nigeria around menstruation and menstrual hygiene. Data was collected quantitatively and analyzed using Epi info version 3.2.05. The mean age of the students was 14.4 +/- 1.2 years; majority was in their mid adolescence. The students attained menarche at 12.9 +/- 0.8 years. Majority had fair knowledge of menstruation, although deficient in specific knowledge areas. Most of them used sanitary pads as absorbent during their last menses; changed menstrual dressings about 1-5 times per day; and three-quarter increased the frequency of bathing. Institutionalizing sexuality education in Nigerian schools; developing and disseminating sensitive adolescent reproductive health massages targeted at both parents and their adolescent children; and improving access of the adolescents to youth friendly services are veritable means of meeting the adolescent reproductive health needs in Nigeria.

    Full Text Available A review of literature was conducted to report on the effectiveness of levonorgestrel intrauterine system (LNG-IUS in women with heavy menstrual bleeding (HMB. The relevant data were obtained by computerized searches of PubMed up to December 2012 and other references available with the authors. Information was obtained from references listed. Studies and case reports were excluded if they did not specifically provide information about LNG-IUS usage in women with HMB. After perusal, each relevant publication was summarized and appraised in terms of whether it contained information relevant to the stated objective. Available data shows that LNG-IUS therapy is effective and safe, providing significant reduction of menstrual bleeding in patients with HMB. LNG-IUS is a good strategy to reduce the number of hysterectomies in women with HMB.

    Dysmenorrhea is a common cause of sickness absenteeism from both classes and work. This study investigated the effect of aromatherapy massage on a group of nursing students who are suffering of primary dysmenorrhea. A randomized blind clinical trial of crossover design was used. In the first treatment phase, group 1 (n = 48) received aromatherapy abdominal massage once daily for seven days prior to menstruation using the essential oils (cinnamon, clove, rose, and lavender in a base of almond oil). Group 2 (n = 47) received the same intervention but with placebo oil (almond oil). In the second treatment phase, the two groups switched to alternate regimen. Level and duration of pain and the amount of menstrual bleeding were evaluated at the baseline and after each treatment phase. During both treatment phases, the level and duration of menstrual pain and the amount of menstrual bleeding were significantly lower in the aromatherapy group than in the placebo group. These results suggests that aromatherapy is effective in alleviating menstrual pain, its duration and excessive menstrual bleeding. Aromatherapy can be provided as a nonpharmacological pain relief measure and as a part of nursing care given to girls suffering of dysmenorrhea, or excessive menstrual bleeding. PMID:23662151

    Full Text Available Women show increased predisposition for certain psychiatric disorders, such as depression, that are associated with disturbances in the integration of emotion and cognition. While this suggests that sex hormones need to be considered as modulating factors in the regulation of emotion, we still lack a sound understanding of how the menstrual cycle impacts emotional states and cognitive function. Though signals for the influence of the menstrual cycle on the integration of emotion and cognition have appeared as secondary findings in numerous behavioral and neuroimaging studies, this has only very rarely been the primary research goal. This review summarizes evidence: (1 that the menstrual cycle modulates the integration of emotional and cognitive processing on a behavioral level, and (2 that this change in behavior can be associated with functional, molecular and structural changes in the brain during a specific menstrual cycle phase. The growing evidence for menstrual cycle-specific differences suggests a modulating role for sex hormones on the neural networks supporting the integration of emotional and cognitive information. It will further be discussed what methodological aspects need to be considered to capture the role of the menstrual cycle in the emotion-cognition interplay more systematically.

    Full Text Available Dysmenorrhea is a highly prevalent complaint and highly undiagnosed gynecologic condition. Dairy products have a potential in the management of menstrual distress, and bovine lactoferrin can help the subjective dysphoria associated with dysmenorrhea. In the present study, we aimed to investigate the effects of a lactoferrin formulation isolated from cow’s milk on menstrual symptoms in volunteers. A double-blind, randomized, placebo-controlled, crossover study of the iron-lactoferrin complex (FeLf was performed in thirty-five healthy Japanese women. Participants received the 150 mg FeLf (per day or placebo from day ten of the luteal phase to day four of the follicular phase. The Moos Menstrual Distress Questionnaire (MDQ was measured for menstrual distress, and heart rate variability was measured as an index of autonomic nerve balance during menses. A visual analog scale for menstrual pain, and a verbal rating scale for quality of life during the first three days of menstruation were measured. The MDQ score for the automatic nervous system subscale was lower and the parasympathetic nervous system activity was greater in FeLf than in placebo for intention-to-treat or per-protocol populations. The other variables were not different between the groups. No treatment-related side effects were observed during the study. The results indicate that FeLf can provide a beneficial effect on the psychological symptoms in women affected by menstrual distress.

    Full Text Available Objectives: To identify the prevalence of various menstrual problems in young females studying health sciences and to identify their association with academic stress. Methods: This was a cross-sectional study, conducted in the health colleges of Immam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia between February 2015 and February 2016. Seven hundred and thirty-eight female students aged 18-25 years anonymously completed menstrual problem identification and perceived stress scale questionnaire. The data was analyzed using the Statistical Package for Social Sciences version 16.0. Results: Ninety-one percent of the students were suffering from some kind of menstrual problem. The different menstrual problems reported, and their incidences included irregular menstruation (27%, abnormal vaginal bleeding (9.3%, amenorrhea (9.2%, menorrhagia (3.4%, dysmenorrhea (89.7%, and premenstrual symptoms (46.7%. High perceived stress (HPS was identified in 39% of the students. A significant positive correlation was found between HPS and menstrual problems. Students with HPS had 4 times, 2 times, and 2.8 times increased odds ratio for experiencing amenorrhea, dysmenorrhea, and premenstrual syndrome (p less than 0.05. Conclusion: The most prevalent menstrual problems (dysmenorrhea and premenstrual symptoms in the target population were strongly associated with stress. Therefore, it is recommended that health science students should be provided with early psychological and gynecological counselling to prevent future complications.

    To assess the association between work in a rotating shift schedule and menstruation characteristics among nurse staff in a prospective study. Rotating shifts have been linked to alterations in the reproductive cycle. In the case of menstrual alterations, the conclusions are not clear. Prospective epidemiological study with follow-up over four months. All the female nurse staff (shifts and characteristics of their menstruation (duration, amount of blood, dysmenorrhoea). They had two types of shifts: (1) Rotating shift schedule (two mornings, two afternoons, one night and two days off) including morning shifts (8:00-15:00), afternoon/evening shifts (15:00-22:00) and night shifts (22:00-8:00), and (2) Day shift schedule including morning shifts (8:00-15:00) and/or afternoon/evening shifts (15:00-22:00). The crude and adjusted odds ratios with 95% confidence interval were calculated using logistic generalised estimating equations (GEE) taking into account the correlations of multiple cycles per worker. One hundred and thirteen workers on the rotating shift and 75 on the day shift participated, and information from 730 menstrual cycles were obtained. There were no differences in prolonged duration, dysmenorrhoea, prolonged duration dysmenorrhoea and excessive bleeding among nurses on rotating shift compared to those on the day shift. For prolonged duration of menstruation, workers with more than five years on the rotating shift showed a slightly lower (nonsignificant) risk compared with those with shift did not show increased risk of having menstrual disorders comparing with day staff. Shifts with short rotation cycles and a progressive sequence do not appear to cause menstrual disorders in nurse staff who work rotating shifts. © 2016 John Wiley & Sons Ltd.

    Today's doping tests involving longitudinal monitoring of steroid profiles are difficult in women. Women have more complex hormonal fluctuations than men and commonly take drugs such as hormonal contraceptives that are shown to affect biomarkers used in these doping tests. In this study, we followed six women's urinary steroid profile during one menstrual cycle, including both glucuronides and sulfate conjugated fractions. Additionally, we studied what happens to the steroidal module of the Athlete Biological Passport (ABP) after administration of an emergency contraceptive (levonorgestrel, NorLevo®). The study shows that there are large individual variations in all metabolites included in the ABP and that the administration of emergency contraceptives may lead to suspicious steroid profile findings in the ABP. Urinary epitestosterone concentration increased during the menstrual cycle, leading to a decrease in the testosterone/epitestosterone ratio. The ratios followed in the ABP varied widely throughout the menstrual cycle, the coefficient of variation (CV) ranging from 4 to 99%. There was a 3-fold decrease in epitestosterone 24 h post administration of the emergency contraceptive pill and androsterone, etiocholanolone, and 5β- androstan-3α,17β-diol concentrations decreased about 2-fold. When analyzed with the ABP software, one of the six women had an atypical profile after taking the emergency contraceptive. Furthermore, we could not find any alterations in excretion routes (i.e., if the metabolites are excreted as glucuronide or sulfate conjugates) during the menstrual cycle or after administration of emergency contraceptive, indicating no direct effect on phase II enzymes.

    Full Text Available Introduction: Issues related to menstruation and its practices are still foggy due to taboos and socio-cultural restrictions resulting in adolescent girls remaining uninformed of the technical facts and hygienic practices to keep good health that is why sometimes it results in to adverse health outcomes. Objectives: (i To find out the age of menarche.(ii To elicit the beliefs, perception and source of information regarding menstruation among adolescent girls. Materials and Methods: A descriptive cross sectional study was conducted among 120 adolescent girls of a higher secondary school situated in Varanasi District. Information was obtained with the help of a predesigned and pretested questionnaire in a local language. Results: About half of the girls (58.3% were aware about menstruation prior to attainment of menarche. The mean age of menarche was found to be 12.98yrs (+0.77.The most common menstrual pattern was 30/3 days. Mother was the first informant regarding menstruation in case of (41.66% of girls. Most of the girls (85.8% believed it as a physiological process. Regarding practices, only 61(50.8% girls informed about the use of sanitary pads during menstruation. Most of the girls 59 (49.16% used old plain cloth as menstrual absorbent. About (82.5% girls practiced different restrictions during menstruation. Conclusion: Menstrual hygiene is still a very important risk factor for reproductive tract infections and it is a vital component of the health education to the adolescent girls. Educational television programmes, trained school nurses/ health personnel, motivated school teachers, and knowledgeable parents can play a very important role in transmitting the critical messages of correct practices about menstrual hygiene to the adolescent girls of today.
