Purpose To study sexual function and distress in women with functional hypothalamic amenorrhea (FHA) compared to women with FHA and an underlying polycystic ovary syndrome (PCOS)-phenotype, considering also their psychometric variables. As a secondary aim, we explored the relationship between sexual functioning and hormonal milieu in these women. Methods This is a retrospective cross-sectional study conducted on 36 women with typical FHA and 43 women with FHA + PCOS-phenotype. The following validated psychometric questionnaires were administered: Female Sexual Functional Index (FSFI), Female Sexual Distress Scale-Revised (FSDS-R), Body Attitude Test (BAT), Bulimia Investigation Test (BITE), State Anxiety Inventory (STAI), Beck Depression Inventory (BDI), Multidimensional Perfectionism Scale (MPS). Available hormones to formulate FHA diagnosis in the standard routine were considered. Results Women with typical FHA reported a significantly lower FSFI total score than women with FHA + PCOS-phenotype (95% CI for median 16–21.3 vs. 21.1–24.1, p = 0.002), whereas the FSDS-R score was similar in the two groups (95% CI for median 6–16 vs. 6–16.3). No statistically significant differences were evident in body attitude, state and trait anxiety, depression, bulimic risk, and perfectionism between the two groups, confirming the two FHA groups were superimposable from a psychometric perspective. State anxiety correlated negatively with the FSFI total score in both typical FHA (rho: − 0.33, p = 0.05) and FHA + PCOS-phenotype (rho: − 0.40, p = 0.009). In the entire study population, a positive correlation was found between luteinizing hormone, androstenedione, and 17ß-estradiol and the total FSFI score (rho: 0.28, p = 0.01; rho: 0.27, p = 0.01, rho: 0.27, p = 0.01, respectively). Conclusion Women with FHA showed a very high rate of sexual symptoms as part of their condition, but those with a typical diagnosis displayed a more severe sexual impairment as compared with the FHA + PCOS-phenotype, in spite of a similar psychometric profile. Sexual distress was equally present in both groups (approximately 4 out of 10 women). Further studies should be designed to investigate the potential role of sex hormones, mainly LH-driven androstenedione, in influencing women’s sexual functioning.

Phthalates are pollutants ubiquitous in the environment. Human exposure to phthalates and their endocrine disrupting effects have been widely studied. Therefore, the European Union forbids phthalates in toys, cosmetic and kitchenware manufacturing. However, phthalate metabolites can still be found in human biological matrices. The purpose of this study is to investigate phthalate exposure over time in a group of Italian healthy newborns. In a prospective cohort study, we enlisted 187 women who gave birth in the University Hospital of Modena, Italy, between January 2019 and May 2020. Urine samples from women after delivery and from their infants at birth, 3 and 6 months were collected and 8 metabolites of 6 phthalates were analysed. Descriptive statistics were calculated and preliminary correlation coefficients tests were performed. Monoethylphthalate (MEP) was always detectable in urine samples. MEP, monomethylphthalate and diethylhexylphthalate metabolites showed an increasing trend over time, while monobutylphthalate and monobenzylphthalate showed decreasing levels over time. Associations between levels of phthalates metabolites in mother and infant pairs at birth were found for a few metabolites, while metabolites in infant samples at 3 and 6 months appeared often significantly associated. Infants’ phthalate exposure in Modena is still high and prolonged over time, even to those more toxic and strictly regulated. As phthalates presence in indoor environment can be a risk factor especially for the most fragile groups of population, such as children, public Health campaigns addressing childbearing age women should stress about the risk posed by these substances and how to avoid their exposure. Moreover, regulatory actions and a stricter legislation should be considered. Key messages • In Italy infant exposure to phthalates, including those strictly forbidden, appears still high and continuous over time. • Public heath intervention and stricter regulatory actions should be considered.

Background Unbalanced nutrients intake and incorrect weight gain can lead to immediate and future adverse health consequences for both mother and child. The Italian Society of Gynaecology and Obstetrics (SIGO), has drawn up a series of nutritional recommendations with the aim of promoting a correct food intake for future mothers. The purpose of our study was to assess adherence to good dietary indications during pregnancy and to evaluate if voluptuary habits could play a role. Methods This cross-sectional study investigated dietary habits during the last trimester of pregnancy. We evaluated the adherence to dietary SIGO recommendations of a sample of pregnant women representative of physiologic full-term pregnancies (n = 572, mean age 33.4±5.2) living in Modena (Italy), recruited between 2016 and 2020. Maternal diet during pregnancy was assessed by a self-administered questionnaire fill in at the hospital after childbirth, evaluating lifestyle habits and usual food intake. Descriptive statistics and bivariate associations (Chi-square tests) were performed. Results More than 50% of women did not comply with SIGO dietary recommendations. Overall, adherence was very low, ranging between 8.4% (sweets) and 38.8% (seafood), for all food categories, excluding coffee and tea (89%), alcohol (76.2%), red wine (99.1%) and seasoning (olive oil 93.4%). Preliminary results suggest that several factors and behaviours, including BMI before pregnancy, age, smoking habits, education, are associated with levels of adherence to different food categories. Conclusions Poor adherence to a proper dietary regimen during pregnancy is a missed opportunity for prevention and demonstrates the importance of promoting public health interventions to improve dietary recommendations adherence. Several initiatives, such as courses, information campaigns, use of social media and counselling can be useful for a nutrition education in pregnancy, raising awareness of the related benefits for both mother and child. Key messages • Nowadays pregnant women’s compliance to diet recommendations is still low. • There is still a lot to do in terms of education and awareness of future mothers.

Obesity is a risk factor for the development of gestational hypertension, with important consequences for both the mother and fetus. This prospective observational study aims to propose an early prediction model of hypertensive disorders in pregnancy among obese women, through the bioelectrical impedance analysis (BIA) at the first trimester, thus allowing early recognition of obese women that are at risk to develop gestational hypertension, in order to target preventive interventions.Singleton obese women (BMI ≥ 30 kg/m2) between the 9th and 12th week of pregnancy were included in the study. The exclusion criteria were chronic diseases, like type 2 diabetes mellitus, hypertension, and other medical pre-existing conditions. Eligible women were followed up at 20, 28, and 36 weeks of gestation by measuring blood pressure, weight, and body composition with the use of the BIA. The diagnosis of gestational hypertension was made after the 20th week of gestation. Pregnancy and perinatal outcomes were then recorded.Of the 479 women included in the study, 85 (17.7%) developed gestational hypertension; the remaining 394 (82.3%) resulted to be normotensive. A higher rate of nulliparous women was found in the hypertensive group (50.6% vs. 37.6%, p = 0.02), together with a higher rate of induction of labor (55.3% vs. 40.9%, p = 0.02) and of small for gestational age (SGA) newborns (12.9% vs. 6.9%, p = 0.03). Significant differences emerged in the body composition between the two groups already from the first trimester, indeed women developing gestational hypertension showed elevated values of Total body Mass, FM, FFM, TBW (p0.02), and of leg's FM, FFM (p0.006). At the multivariate logistics regression, the risk of developing gestational hypertension resulted higher in women with elevated total body water levels in the first trimester (OR 1.10 95% CI 1.04 -1.92).The BIA is a rapid, easy, non-invasive, and inexpensive tool to evaluate the body composition of obese pregnant women. It represents a promising predictor of hypertensive disorders in pregnancy, which allows an early identification of the patients at risk of developing gestational hypertension, thus opening a window of opportunity for strictly monitoring and target preventive intervention.

Background Multiple gestations represent a considerable proportion of pregnancies delivering in the late preterm (LP) period. Only 30% of LP twins are due to spontaneous preterm labor and 70% are medically indicated; among this literature described that 16–50% of indicated LP twin deliveries are non-evidence based. As non-evidence-based delivery indications account for iatrogenic morbidity that could be prevented, the objective of our observational study is to investigate first neonatal outcomes of LP twin pregnancies according to gestational age at delivery, chorionicity and delivery indication, then non evidence-based delivery indications. Methods Prospective cohort study among twins infants born between 34 + 0 and 36 + 6 weeks, in Emilia Romagna, Italy, during 2013–2015. The primary outcome was a composite of adverse perinatal outcomes. Results Among 346 LP twins, 84 (23.4%) were monochorionic and 262 (75.7%) were dichorionic; spontaneous preterm labor accounted for 85 (24.6%) deliveries, preterm prelabor rupture of membranes for 66 (19.1%), evidence based indicated deliveries were 117 (33.8%), while non-evidence-based indications were 78 (22.5%). When compared to spontaneous preterm labor or preterm prelabor rupture of membranes, pregnancies delivered due to maternal and/or fetal indications were associated with higher maternal age (p p p p p p p p p p Conclusion Our study suggests that the decision to deliver or not twins in LP period should consider gestational age at delivery as the main determinant infants’ prognosis. Delivery indications should be accurately considered, to avoid iatrogenic early birth responsible of preventable complications.

Inositol is a carbocyclic sugar polyalcohol. By epimerization of its hydroxyl groups, nine possible stereoisomers can be generated, two of major physiological and clinical relevance: myo-inositol and D-chiro-inositol. Myo-inositol and D-chiro-inositol are normally stored in kidney, brain and liver and are necessary for functions, such as signal transduction, metabolic flux, insulin signaling, regulation of ion-channel permeability, stress response and embryo development. In this narrative review, we summarize the mechanisms by which myo-inositol and D-chiro-inositol can be synthesized and absorbed and their possible role in the etiopathogenesis of neural tube defects.We performed an online search in the PubMed database using the following keywords: "inositol", "D-chiro-inositol", "myo-inositol", "neural tube defects and inositol".Inositol requirements are partly met by dietary intake, while the rest is synthesized endogenously. Inositol deficiency may be involved in the pathogenesis of diseases, such as metabolic syndrome, spina bifida (a neural tube defect), polycystic ovary syndrome and diabetes. Supplementation of the two inositol stereoisomers, D-chiro-inositol and myo-inositol is important to prevent these conditions.Inositol is fundamental for signal transduction in the brain, kidneys, reproductive organs and other tissues in response to neurotransmitters, hormones and growth factors. Various genes are involved in inositol metabolism and associated pathways. Altered inositol concentrations are observed in several diseases. Analysis of the genes involved in inositol metabolism may provide important information for the clinical management of these conditions.

BackgroundAs uterine rupture may affect as many as 11/1000 women with 1 prior cesarean birth and 5/10.000 women with unscarred uterus undergoing labor induction, we intended to estimate the prevalence of such rare outcome when PGE2 is used for cervical ripening and labor induction.MethodsWe searched MEDLINE, ClinicalTrials.gov and the Cochrane library up to September 1st 2020. Retrospective and prospective cohort studies, as well as randomized controlled trials (RCTs) on singleton viable pregnancies receiving PGE2 for cervical ripening and labor induction were reviewed. Prevalence of uterine rupture was meta-analyzed with Freeman-Tukey double arcsine transformation among women with 1 prior low transverse cesarean section and women with unscarred uterus.ResultsWe reviewed 956 full text articles to include 69 studies. The pooled prevalence rate of uterine rupture is estimated to range between 2 and 9 out of 1000 women with 1 prior low transverse cesarean (5/1000; 95%CI 2-9/1000, 122/9000). The prevalence of uterine rupture among women with unscarred uterus is extremely low, reaching at most 0.7/100.000 (ConclusionsUterine rupture is a rare event during cervical ripening and labor induction with PGE2.

Leiomyomas are the most common uterine benign tumor, and their malignant counterpart leiomyosarcomas are extremely rare. Despite this, a preoperative diagnosis could be useful for safe surgical minimally invasive management. At present, some clinical and ultrasound findings help recognizing lesions at risk of malignancy. We tried to implement a technique for the preoperative diagnosis for lesions at risk performing ultrasound-guided biopsies of suspected lesions in ten patients. Among them, one case was diagnosed as malignant by the needle biopsy. All patients underwent surgery for myomectomy or hysterectomy, and the histology was confirmed in all cases. No complications occurred. The review of the literature shows other similar experiences of preoperative biopsy of uterine lesions, showing good results for the differential diagnosis between uterine sarcoma and leiomyoma. In our experience, despite the small number of patients enrolled, this technique is safe and effective to plan minimally invasive surgery of uterine fibroids.

Introduction Antithrombin levels are often reduced in preeclampsia and infusion of antithrombin concentrates has been reported to prolong gestation in severe preeclampsia. We aimed to evaluate efficacy and safety of high-dose antithrombin (ATIII) supplementation in patients with single pregnancies and preeclampsia occurring before 30 weeks of gestation. Materials and methods In November 2004 a double-blind, placebo-controlled trial (code KB033) was started in 13 Italian centers. The planned sample size was of 240 patients (intention-to-treat, ITT population) to detect a 30% relative risk reduction of the primary endpoint, composite perinatal morbidity. Eligible patients were randomized to high dose AT (3000 IU/daily, ATIII Kedrion S.p.A., Italy), or placebo (1% glycine) for 7 days or less until delivery, whichever came first. The per-protocol (PP) population was restricted to patients receiving at least two days of treatment. Results The study was terminated by the sponsor in October 2007 after the enrolment of 38 evaluable patients – 20 randomized to high dose AT and 18 to placebo, 27 treated for 2 days or more – out of 164 screened patients. Enrolment failures were mainly represented by requirement for immediate delivery and consent refusal (91 patients). The primary endpoint occurred in 15 of 38 patients (39.5%), with a relative risk in the AT arm of 0.85 (95% CI 0.42–1.75) and 0.79 (95% CI 0.30-2.11) in the ITT and PP populations, respectively. Living neonates in the two arms had similar weight at birth, Apgar scores, and duration of hospitalization in neonatal ICU. In mothers, AT supplementation was associated with reduced blood loss at delivery and with surrogate laboratory markers (LDH, d -dimer). Conclusions The results of this markedly underpowered trial, albeit suggestive of a potential maternal benefit, cannot support high-dose AT supplementation to improve fetal/neonatal outcomes in early preeclampsia.

Objective: To provide the first Italian data on pathogens causing early-onset sepsis (EOS) and their antimicrobial susceptibility, after the successfully prevention of Group B streptococcus (GBS) EOS. Methods: Retrospective area-based cohort study from Emilia-Romagna (Italy). Cases of EOS registered (from 2009 to 2012) in all gestational age neonates were reviewed. Results: Live births (LB) numbered 146 682. Ninety neonates had EOS and 12 died (incidence rates of 0.61 and 0.08/1000 LB, respectively). EOS and mortality were the highest among neonates with a birth weight n = 27, 0.18/1000 LB) and Escherichia coli (n = 19, 0.13/1000 LB). Most infants affected by E. coli EOS were born preterm (n = 13), had complications (n = 4) or died (n = 7). Among 90 isolates tested, only 3 were resistant to both first line empirical antibiotics. Multivariate logistic regression analysis showed that low gestational age, caesarean section and low platelet count at presentation were significantly associated with death or brain lesions (area under ROC curve = 0.939, H-L = 0.944, sensitivity 76.0%, specificity 90.7%). Conclusions: GBS slightly exceeds E. coli as a cause of EOS. However, E. coli is the prominent cause of death, complications and in most cases affects preterm neonates. Empirical antimicrobial therapy of EOS seems appropriate.

In mammals endorphinergic systems have been shown to modulate reproductive processes and beta-endorphin (beta-EP) has been found to influence sexual functions, acting at the hypothalamus-pituitary-gonadal axis level. Using immunocytochemical and in vitro studies, evidence for a diffuse pro-opiomelanocortin-related opioid system in the lizard Podarcis s. sicula was produced. In the testis, beta-EP immunoreactivity showed seasonal variation, being most pronounced in the interstitial cells of sexually quiescent lizards (December). Reverse-phase high-performance liquid chromatography, coupled with radioimmunoassay and immunocytochemistry, showed that beta-EP and acetyl beta-EP increased during December, while their concentrations were low during April, when the highest testicular activity occurred. Using in vivo studies, it was found that naltrexone treatment, blocking pituitary opioid receptor, increased androgen levels in the plasma and in the testis. It was also found with in vitro studies that the endogenous opioid system inhibits gonadotrophin release and therefore androgen production by the testis. The data reported here provide evidence for the physiological role played by opioid peptides at the pituitary level to regulate the seasonal reproductive activity of the lizard Podarcis s. sicula.

Several reports have suggested the use of acupuncture as a useful treatment for hyperemesis gravidarum (HG), in particular the effects on nausea intensity was underlined. The aim of this study was to compare the efficacy of acupuncture sessions plus acupressure with a metoclopramide/vitamin B12 treatment.In this study we randomized 88 pregnant patients suffering from HG to receive either acupuncture sessions plus acupressure (acupuncture group) or metoclopramide infusion (metoclopramide group) supplemented by vitamin B12 complex. Somatic symptoms and the ability to achieve the daily routine activity (functioning) were evaluated. Acupuncture sessions were performed at the hospital twice a week for 2 weeks according to the traditional Chinese medicine criteria. Acupression was applied for 6-8 h/day. In the metoclopramide group, patients received at hospital metoclopramide infusion (20 mg/500 mL saline for 60 min) twice a week for 2 weeks. An oral supplementation with vitamin B12 complex (30 mg/day) was also prescribed.Both treatments reduced vomiting episodes and then nausea intensity with a consequent improvement in the rate of food intake. The effect of acupuncture seems to be progressive, increasing at the end of treatment whereas pharmacological approach has a prompt effect in responders remaining stable thereafter. Moreover, acupuncture was significantly more effective than drugs in improving functioning.In our study for the first time acupuncture, applied accordingly to Chinese formula, was compared to drugs demonstrating the same effect of both treatments on HG symptoms. Interestingly, functioning was significantly improved just by acupuncture. Even if the effect of acupuncture on HG discomfort remains to be confirmed, the reports on the effect of acupuncture on psychosocial variables could represent a further advantage of acupuncture application and provide an incentive to widen the base of the research.

Several effects of melatonin are modulated by gonadal steroids and are reduced in ageing women. Administration of melatonin reduces internal carotid artery pulsatility index (PI), and blood pressure in young individuals. Whether these effects are conserved in postmenopausal women and are influenced by hormone replacement therapy (HRT), was herein investigated.Randomised, double-blind placebo controlled study.Twenty-three postmenopausal women of which 11 were unreplaced with HRT and 12 on the oestrogenic phase of continuous transdermal estradiol (50 microg/day) plus cyclic medroxyprogesterone acetate (5 mg/day x 12 days every 28 days).Internal carotid PI, by colour Doppler, and supine blood pressure were evaluated 90, 180 and 240 minutes following the oral administration of melatonin (1 mg) or placebo. Levels of nitrites/nitrates (NOx), the stable derivatives of nitric oxide, were also evaluated in samples collected 90 minutes following the administration of placebo or melatonin.In women not on replacement therapy melatonin was ineffective. In HRT-treated women, melatonin reduced internal carotid artery PI (P = 0.005). The effect was maximal within 90 minutes, and maintained for at least 240 minutes, with melatonin levels in the nocturnal physiological range. Systolic and diastolic blood pressures were reduced of 8 mmHg (P = 0.038) and 4 mmHg (P = 0.045), respectively, while NOx levels were significantly increased (P = 0.024).The circulatory response to melatonin is conserved in postmenopausal women with but not without hormone replacement therapy. Maintenance of the cardiovascular response to melatonin, may be implicated in the reduced cardiovascular risk of postmenopausal women with hormone replacement therapy.

The present study investigates the role of melanotrope proopiomelanocortin-derived peptide in the interrenal stress response to different stressors in male gilthead sea bream, Sparus aurata. Plasma cortisol and acetyl salmon endorphin (acetyl s-EP), as well as pituitary acetyl s-EP contents, were measured during two stress paradigms: (a) long-term (1-month) confinement and crowding, and (b) short-term (60-min) confinement, crowding, and manipulation. In addition, naltrexone, a highly specific opioid receptor antagonist, was employed in some experimental groups to evaluate the adaptability of the opioid response to interrenal stress. In the long-term (1-month) confinement and crowding, higher plasma cortisol levels and acetyl s-EP concentrations than in the control group were found. However, although plasma cortisol levels significantly increased in both types of stress paradigm, a significant rise in plasma acetyl s-EP was observed only in the case of confinement plus crowding. These data seem to suggest a direct correlation of acetyl s-EP plasma levels exclusively in cases of specific stress, and support previous observations about the different nature of the pituitary-interrenal stress response in salmonids and in mammals. The results obtained in the short-term (60-min) experiments demonstrate the double activation of both the opioid and corticotrope systems when manipulation plus crowding was applied.

It is well known that pregnancy is a condition in which plasma magnesium falls because of accumulation of the ion in the placenta and fetus. Magnesium (Mg) is therefore widely given as a supplement during pregnancy, particularly in cases of preterm labour. In our experience, the combination of oral Mg (magnesium pyrrolidone carboxylic acid) at a dose of 360 mg/day with conventional ritodrine treatment allows a reduction in ritodrine dosage, accompanied by a significant reduction in side effects. We therefore evaluated changes in fetal blood flow, using pulsed Doppler, in women submitted to combined magnesium and ritodrine treatment compared to those treated with ritodrine plus placebo. The Mg-treated group showed a decrease in vessel resistance both in the umbilical artery and in the fetal middle cerebral artery, indicating that fetal vasculature is sensitive to exogenous Mg. Measurement of plasma and mononuclear cell Mg showed an intracellular increase in the cation of about 10 per cent. We conclude that oral magnesium supplementation in pregnancy is safe and that it has a positive effect on the fetal circulation.

Risk of needlestick injuries (NSIs) is high in surgical staff. Medical students and trainees have reported the highest rate of NSIs, and Obstetrics and Gynecology is considered a high-risk specialty. The risk associated to NSIs is further increased by the high prevalence of blood borne pathogens in the population. Nevertheless, the degree of concern about contraction of these serious infections has been reported significantly lower over time, showing diminishing attitudes toward prevention of exposure and lack of consideration as a major problem, in fact most of NSIs resulted unreported. Therefore, education is fundamental to change individual attitudes and behaviors, to improve awareness and increase the use of standard protections, in order to reduce the injury rate and implement reporting to hospital surveillance systems. The proposed study aims to assess NSIs in trainees currently attending residency programs in Obstetrics and Gynecology in all academic hospitals of Italy, with a standardized, pre-piloted, national- based survey. At this purpose, we developed the Obstetrics Needlestick Injury Questionnaire (ONSI-Q), a 40-items survey that will be completed via a web- based platform. The ONSI-Q investigates real incidence of NSIs, adopted protection practices, presence of associated risk factors, and attitudes and rate of the reported accidents among trainees during obstetric procedures (suture of perineal tear/episiotomy and cesarean section). These results will provide the opportunity to investigate an underestimated priority, in order to encourage educational practices with the aim to improve prevention and reporting strategies, and therefore increase occupational safety in this high-risk surgical specialty.

The present study evaluates the plasma level changes in beta-lipotropin and beta-endorphin in nine women at term throughout spontaneous labor, in ten pregnant women undergoing elective cesarean section in the absence of uterine contractions, and in ten women submitted to emergency cesarean section because of fetal distress occurring during labor. A basal plasma sample was taken before labor in the 39th week of pregnancy. Two subsequent samples were then obtained before and after parturition, together with umbilical cord samples at birth. beta-lipotropin and beta-endorphin were measured by radioimmunoassay after silicic acid plasma extraction and gel filtration. In cases of spontaneous labor, there was a progressive increase in opioid concentrations as labor progressed, the maximal values being observed after delivery. Cord values were similar to those observed in the mother, without showing any relationship to them. Pregnant women undergoing cesarean section in the absence of labor show constant beta-lipotropin and beta-endorphin concentrations both before and after fetal extraction, both values being significantly lower than those found at delivery after spontaneous labor. beta-Endorphin neonatal levels were significantly higher than in the respective mothers and were in the same range as those of infants born through vaginal delivery. In the third group (cesarean section performed at the first stage of labor), presurgical opioid levels were higher than in women at the same stage of spontaneous labor, whereas postextraction values showed a wide range, with mean values similar to those observed after spontaneous delivery.(ABSTRACT TRUNCATED AT 250 WORDS)

On the basis of the behaviour during menstrual cycle of the pituitary hormones plasma levels, the Authors have studied during the different periods of the cycle (follicular, ovulatory and luteal) the effects of OGTT and ITT's on the plasma levels of Glucose, insulin, HGH and Cortisol. Significantly lower levels of IRI, HGH and Cortisol were found in follicular phase compared to ovulatory period and luteal phase except for Cortisol in luteal phase. A slightly higher glucose tolerance was found in follicular phase as well as a reduced hypoglicemia under insulin load. Reduced HGH response to ITT was found in follicular phase as well as a reduced Cortisol response compared to the results observed in ovulatory and luteal phase. These data sustain the concept that hormonal variations occurring in an ovulatory cycle are also capable of modifying the woman's body response to various stimuli such as OGTT and ITT.

Plasma estradiol (E2), progesterone (P), beta-endorphin (beta-EP) and beta-lipotropin (beta-LPH) were measured in the luteal phase of 8 patients affected by menstrually-related migraine (M) and in 3 cases of catamenial epilepsy (CE). Plasma P and E2 of the M patients were lower than in the CE group. Both beta-LPH and beta-EP showed a reduction in M patients near menses, while the opposite pattern was found in CE. These data demonstrate that premenstrual syndrome is sustained by different, neurobiological dysfunction even if endogenous opioids could be involved in both migraine and epilepsy.

To test the hypothesis that labor onset could be the result of a reduced release of nitric oxide (NO).Out of 91 consecutive healthy nulliparous women at term serum citrulline (Cit) and arginine (Arg) levels were measured at least twice in 37 subjects, by the means of HPLC with fluorometric detection. Twenty cases underwent a spontaneous onset of labor (group A) while in 17 cases labor was induced (group B) because of pregnancy prolongation or amniotic fluid reduction.Cit and Arg levels were unaffected by the gestational age. In group A, Cit levels undergo a progressive decrease toward the day of labor (from 32.9+/-4.7 microM/L the day - 18,-5 to 27.7+/-7.8 the day -4,0; p=0.012) whilst they remained stable in group B (from 33.3+/-7.7 to 34.2+/-9.2). No significant changes were observed in Arg levels. Cit/Arg ratio remained stable in group A whereas it showed a trend to increase in group B.These data indirectly suggest a reduced release of NO toward term. This phenomenon could play a permissive role in the spontaneous onset of labor of healthy nulliparous women.

The most striking effect of increased survival and improved quality of life in HIV-infected women undergoing antiretroviral therapy is the feasibility of motherhood-desire satisfaction. However, such advantages are often associated with drug-related metabolic toxicities, particularly relevant in the pregnancy context. Recent guidelines provide recommendations and trends for the use of antiretroviral therapy in pregnant women, but current literature falls short of providing specific insights on the need for metabolic monitoring and treatment in HIV-infected pregnant women. In this review we provide specific insight into the state-of-the-art of: detection, evaluation, and management of metabolic alterations in this special population. Pregnancy is in fact a metabolic transition process, potentially associated with specific diseases in the mother, in the newborn, and in the adulthood of the child. We will not simply discuss antiretroviral therapy metabolic toxicities, but rather their interaction with the physiological metabolic changes occurring during pregnancy. Close monitoring is needed to diagnose metabolic alterations that can lead to adverse outcomes in the mother, in the newborn, and potentially in adulthood. Lifestyle interventions and an appropriate metabolic tailoring of antiretroviral therapy drugs need to be considered in the prevention and treatment of metabolic alteration during pregnancy.

Reduced magnesium (Mg) levels have been reported in women affected by premenstrual syndrome (PMS). To evaluate the effects of an oral Mg preparation on premenstrual symptoms, we studied, by a double-blind, randomized design, 32 women (24-39 years old) with PMS confirmed by the Moos Menstrual Distress Questionnaire. After 2 months of baseline recording, the subjects were randomly assigned to placebo or Mg for two cycles. In the next two cycles, both groups received Mg. Magnesium pyrrolidone carboxylic acid (360 mg Mg) or placebo was administered three times a day, from the 15th day of the menstrual cycle to the onset of menstrual flow. Blood samples for Mg measurement were drawn premenstrually, during the baseline period, and in the second and fourth months of treatment. The Menstrual Distress Questionnaire score of the cluster "pain" was significantly reduced during the second month in both groups, whereas Mg treatment significantly affected both the total Menstrual Distress Questionnaire score and the cluster "negative affect." In the second month, the women assigned to treatment showed a significant increase in Mg in lymphocytes and polymorphonuclear cells, whereas no changes were observed in plasma and erythrocytes. These data indicate that Mg supplementation could represent an effective treatment of premenstrual symptoms related to mood changes.
