    Progesterone levels were measured by radioimmunoassay in the last milk of seven dairy cows in 5-75 days post-partum. The progesterone levels were from 0.1 to 1.5 ng/ml and averaged 0.4 +- 0.2 ng/ml for the last milk of the seven cows. A range of 0.3 to 0.7 ng/ml for average progesterone levels of the seven cows can be estimated. Two ovarian cycle activities in post-partum of cow No. 43 were observed and a ovulation on 15-20 days post-partum was revealed. The peak value after 20 days post-partum was 3.0 ng/ml. The progesterone level after peak value was declined, and reached to about 0.2 ng/ml on 35 days post-partum. The changes of ovarian activities were exhibited again in 35-55 days post-partum. The progesterone levels of cow No. 43 were lower in luteal phase oestrous cycles post-partum than that from the other cows in normal luteal phase oestrous cycles.

    This study was carried out on 18 calved dairy cows, near the town of Curitiba-PR-Brazil. The animals were submitted weekly to a rectal palpation of the genital tract and the uterine involution and ovarian activity were considered. The rectal palpations began from the 7 th day postpartum till the 49 th day. at the same milk samples the first morning milk were taken on the 9 th week. The progesterone (P 4 ) level determination of the milk was established by radioimmunoassay. The findings of the research showed: the postpartum oestrus was observed at the 28.5 th day and the corpus luteum was detected on the 34.5 th day. The period from oestrus to the first high progesterone level post partum was 5.5 days. The uterine involution period was carried on the 24.1 th day. The progesterone dominant period was shorter and had duration of 11.5 days on the first oestrus cycle post partum. The progesterone concentration from the first Corpus luteum post partum was low (1.9 ng/ml milk). The anoestrus rate until 49 th day postpartum was 33.3% and the silent heat rate reached 61.1%.

    Milk samples were taken at weekly intervals from 77 dairy cows on days 23, 30, 37, 43 and 50 post-partum (pp) in order to monitor ovarian activity through progesterone concentration measurement. Skim milk samples were assayed for progesterone by radioimmunoassay using kits provided through the FAO and IAEA. Oestrus, clinical examinations, treatments, artificial insemination and pregnancy diagnosis were recorded. The profiles of progesterone concentration and oestrus occurrence combined with behavioural and clinical data indicated that the study cows were in the following reproductive states: I - normal, 38%; II - 'silent' oestrus, 12%; III - prolonged luteal activity, 13%; IV - irregular cyclic activity, 23%; and V - anoestrus, 13%. After artificial insemination, 89% (25/28) of normal, 77% (7/9) of silent oestrus, 50% (5/10) of prolonged luteal activity, 82% (14/17) of irregular cyclic activity and 80% (8/10) of anoestrous cows eventually became pregnant either with or without hormone treatment. With the exception of the anoestrous group, these results seem to support the idea that once a week sampling for progesterone over a seven week period pp is sufficient to monitor the ovarian activity and predict the fertility of a dairy herd.

    Full Text Available Thirty adult goats were classified at parturition into two body condition score (BCS groups: BCI (n=16 with a score of 2.7 and BCII (n=14 with a score of 2.0. On the fiftieth day postpartum, oestrus was synchronized by CIDR for 5 days. Upon CIDR removal (Day 0, they received 1 mL of PGF2α IM and mated for 72 hours. Kids were kept with does and weaned at 40 days of age. Blood samples were taken at 0, 1, 4, 8 and 21 days after CIDR removal for progesterone assay. The BCI group showed a greater weight loss compared to the BCII group, and BCS before synchronization was 1.9±0.08 and 1.6±0.07 for the BCI and BCII groups, respectively (Pvs 36%; Pvs 1.25; Pvs 0.25; P<0.05. Progesterone concentration was higher in pregnant does in BCI. A positive relationship was found between progesterone level at CIDR removal and BCS at parturition (0.57; P<0.01, also between progesterone level at 21 days after CIDR removal and BCS at parturition (0.47; P<0.05, or BCS before synchronization (0.51; P<0.05. We conclude that oestrus response to postpartum CIDR synchronization appeared to be slightly dependent on BCS. However, goats with low BCS at oestrus synchronization exhibited a reduction in pregnancy rate.

    The blood samples were collected from 22 Luxi cattle, aged 2.5-8 years, from calving day (day 0) to 80 days postpartum at 4-day interval. Progesterone (P 4 ) levels in plasma were determined by solid phase RIA. The results are summarized as follows: P 4 levels in plasma of the cows remained at 0.34 +- 0.04-0.55 +- 0.06 ng/ml before 10.6 +- 3.9-13.6 +- 4.4 days postpartum, then they began to rise and the ovarian activity appeared. The plasma P 4 profiles of the cows can be classified into 4 types, characterized by (I) 3 normal cycles; (II) a short cycle followed by 2 normal cycles; (III) a normal cycle followed by a short cycle and a normal cycle; and (IV) some irregular cycles respectively. The lowest and the highest P 4 levels were 0.45 +- 0.15-0.60 +- 0.38 and 2.65 +- 1.95-4.17 +- 2.35 ng/ml respectively in luteal cycles. It is also concluded that determining plasma P 4 concentrations at 4-day interval can precisely identify the oestrus cycles of cows, and that the solid phase P 4 -RIA have practical value for determination of plasma P 4 concentration

    In this paper, the effect of clinical symptoms of uterine inflammation on progesterone profile characteristics was quantified in dairy cows. A continuous scale based on visual observation of vaginal discharge (the previously developed D-index) was used to describe the clinical symptoms....... Progesterone profiles in milk were used to describe the ovarian cycles, and to determine the distinguishing features of these profiles, a multivariate statistical procedure (principal component analysis) was performed. Significant negative effects of the D-index were seen during the first and second postpartum...

    The relationship of the changes of hormone in patients with postpartum depressive disorder on 28-32 weeks of pregnancy, 1 week and 4 weeks postpartum was studied. Depress affection and anxious affections were measured in 200 postpartum women by self-rating depression scale and self-rating anxiety scale. Serum estradiol (E 2 ) and progesterone (P) levels in postpartum women were measured by RIA with control group. Results showed that the prevalence rate of depress affection was 11% and that of anxious affection was 14%. The serum levels of P on the 1 week postpartum, E 2 in antepartum were showed higher in the depressed group compared with control group. There was a significant difference in the changes of serum E 2 before and after delivery between the depressed group and control group (P 2 and P levels in the patients with postpartum depression after delivery.

    The aim of this study was to investigate the effect of applying a progesterone-based oestrous synchronization protocol at 51-57 days postpartum in high-producing dairy cows. The data analysed were derived from 1345 lactating cows. Cows between 51 and 57 days postpartum were assigned to the groups: control, PRID (receiving a progesterone-releasing intravaginal device for 9 days, and prostaglandin F(2α) 24 h before PRID removal) or GnRH-PRID (the same as the PRID group plus GnRH at PRID insertion). Oestrus was detected by using pedometers and confirmed by examination of the genital tract at AI. Oestrous and conception rates before days 71-77 postpartum, pregnancy loss in early pregnant cows or the cumulative conception rate registered on day 120 postpartum were considered as the dependent variables in four consecutive logistic regression analyses. Based on the odds ratios, the oestrous rate increased by a factor of 1.73 in cows showing oestrus before treatment for each unit increase in the number of previous oestruses; decreased by a factor of 0.44 in the control group with respect to the treatment groups; and by a factor of 0.61 in cows without luteal structures at treatment with respect to cows with corpora lutea. The conception rates of cows inseminated before days 71-77 postpartum remained similar across the groups, whereas the likelihood of pregnancy loss for cows becoming pregnant during this period was 0.11 times lower in the PRID group than in the control. Based on the odds ratio, the likelihood of a higher cumulative conception rate on day 120 postpartum: increased in cows showing oestrus before treatment by a factor of 1.41 for each unit increase in the number of previous oestruses, was reduced 0.56-fold in control cows compared with treated cows, and was also reduced by a factor of 0.98 for each kilogram of milk production increase recorded at treatment. In conclusion, although oestrous synchronization programmes performed in this study did not improve

    The reproductive performance of postpartum Santa Inês (SI) and Morada Nova (MN) ewes treated with insulin or progesterone hormones in association with ram effect was evaluated. Ewes from SI (n = 69) and MN (n = 69) breeds were randomly allocated to three groups of each breed (T1-ram effect only; T2-ram effect + insulin; T3-ram effect + progesterone). Progesterone concentrations (ηg/ml; mean ± SD) before and after introduction of rams (n = 6) were 0.51 ± 0.22 and 3.78 ± 0.68 (T1), 0.65 ± 0.21 and 3.77 ± 0.78 (T2) and 0.52 ± 0.21 and 3.84 ± 0.84 (T3) in SI ewes and 0.74 ± 0.19 and 3.71 ± 0.56 (T1), 0.70 ± 0.21 and 3.79 ± 0.75 (T2) and 0.81 ± 0.14 and 3.87 ± 0.80 (T3) in MN ewes, respectively. Thus, lower progesterone concentrations were found before the introduction of rams (p ewes and at 64 (T1), 40 (T2) and 44 (T3) hr in MN ewes. The mean number of ovulations was similar between groups (p > .05), was 1.3 ± 0.51 (T1), 1.5 ± 0.54 (T2) and 1.6 ± 0.51 (T3) in SI ewes and 1.3 ± 0.51 (T1), 1.6 ± 0.51 (T2) and 1.6 ± 0.51 (T3) in MN ewes. In conclusion, the ram effect alone is effective at inducing and synchronizing oestrus in sheep under postpartum anoestrus, irrespective of hormone treatments. © 2017 Blackwell Verlag GmbH.

    2007-10-01

    Withdrawal from high levels of progesterone in rodents has been proposed as a model for premenstrual syndrome or postpartum depression. Forced swim test (FST) immobility, used to model depression, was assessed in intact female DBA/2J mice following progesterone withdrawal (PWD) or treatment with the 5alpha-reductase inhibitor finasteride. Following 5 daily progesterone injections (5 mg/kg IP) FST immobility increased only in mice withdrawn for 3 days (pimmobility. PWD and finasteride treatment, both of which reduce allopregnanolone levels, were associated with increased FST immobility in female DBA/2J mice. These findings suggest that decreased levels of the GABAergic neurosteroid allopregnanolone contribute to symptoms of PWD. Future studies of PWD may provide information about human conditions that are associated with hormone changes such as premenstrual syndrome or postpartum depression.

    Full Text Available "nBackground: Postpartum depression is a mood disorder that has harmful effects on mothers, infants, family and relationships. Acute decrease of progesterone after delivery has been proposed as a cause for postpartum depression. This hormone can affect neurotransmitters' function. Zinc (Zn and magnesium (Mg as trace elements exert their antidepressant effects through neurotransmitter pathways. On the other hand, thiamin (Vit B1 deficiency leads to depression in animal models. The aim of this study was to evaluate effects of combination of zinc, magnesium and thiamine on postpartum depression and role of nitrergic system. "n"nMethods: One hundred ten female mice in five groups were used. Postpartum depression was conducted using progesterone injections. Combinations of Zinc chloride, magnesium chloride and thiamine HCL were administered 30 minutes before open field and forced swimming test (FST. In order to investigate role of nitrergic system, L-arginine and LNAME were administered. "n"nResults: All treatment groups spent less immobility time than the control group (p< 0.05. Combined administration of Zn+ Mg+ Vit B1 caused the most reduction in immobility time. Administration of L-NAME in Zn+ Mg+ Vit B1 group caused reduction in immobility time while administration of L-arginine caused increase in immobility time in the same group. "nConclusion: Zinc, magnesium and thiamine can improve depressive symptoms by nitrergic pathway. These elements as supplement compounds could be alternatives for antidepressants in postpartum period.

    Eighteen cross-bred buffaloes (F 1 , local breed x Murrah) and 19 cross-bred cows (F 1 , local breed x Holstein Friesian), 4-6 years of age, were used in the study to determine the potential of milk progesterone measurement as an aid in characterizing the onset of postpartum ovarian activity and for early pregnancy diagnosis. The first oestrous cycle, based on milk progesterone, commenced between days 40-50 postpartum in 17% of the buffaloes but between days 25-35 postpartum in 21% of the cows. At days 61-100 postpartum, 33% of the buffaloes had cycling ovaries with progesterone concentrations of 3.23-4.02 ng/mL, while 53% of the cows had cycling ovaries during the same period with progesterone concentrations of 3.52-4.16 ng/mL. During the oestrous cycle, the progesterone level showed peak elevations on day 15 in buffaloes and on day 9 in cows. The milk progesterone profiles of the buffalo took longer to reach peak levels, but declined faster than those in the cow. The accuracy of positive pregnancy diagnosis was 78% in buffaloes and 83.3% in cows, but the accuracy of diagnosing non-pregnancy was 100% in both species. (author). 4 refs, 2 figs, 1 tab

    Beckley, Ethan H; Scibelli, Angela C; Finn, Deborah A

    2011-07-01

    Progesterone withdrawal has been proposed as an underlying factor in premenstrual syndrome and postpartum depression. Progesterone withdrawal induces forced swim test (FST) immobility in mice, a depression-like behavior, but the contribution of specific receptors to this effect is unclear. The role of progesterone's GABA(A) receptor-modulating metabolite allopregnanolone in depression- and anxiety-related behaviors has been extensively documented, but little attention has been paid to the role of progesterone receptors. We administered the classic progesterone receptor antagonist mifepristone (RU-38486) and the specific progesterone receptor antagonist CDB-4124 to mice that had been primed with progesterone for five days, and found that both compounds induced FST immobility reliably, robustly, and in a dose-dependent fashion. Although CDB-4124 increased FST immobility, it did not suppress initial activity in a locomotor test. These findings suggest that decreased progesterone receptor activity contributes to depression-like behavior in mice, consistent with the hypothesis that progesterone withdrawal may contribute to the symptoms of premenstrual syndrome or postpartum depression.

    A system for the measurement of progesterone in bovine milk by radioimmunoassay has been developed and validated. This assay includes an iodine tracer purified by HPLC, the standard prepared in fat-free milk and an antibody anti-progesterone combined with second antibody. The detection limit of the assay is at 0.2 nmol/L calculated from the maximum binding menus two standard deviations and the precision is satisfactory. In the recovery assay was used 4 milk different samples and the result was 98% of recuperation. The progesterone was determinate in milk samples from post-partum animals taking samples three times per week for 40 days. The assay is simple, rapid and possibility the progesterone measurement without sample dilution, distinguish the cyclic changes of this hormone that reflect the ovarian activity in the animals.

    The aim of the studies was to monitor the reproductive performance of Icelandic dairy cow herds with and without histories of fertility problems under normal farming conditions. Artificial inseminations and calvings were recorded, pregnancy was diagnosed by rectal palpation, and progesterone concentration was measured by radioimmunoassay in sequential samples of milk. Blood samples were collected at regular intervals and the concentrations of glucose, urea, calcium and magnesium were determined. Clinical ketosis and low glucose were found in one third of the cows on problem farms. The mean time of first post-partum ovulation was 49 days for cows with ketosis, compared with 34 days for cows free of ketosis. Cows in the normal herds ovulated considerably later than is reported for many other breeds of dairy cows; however, the time of first post-partum AI, the time of conception and the conception rate were similar to those reported for other breeds. The effects of season and herd were statistically significant for the time of first post-partum ovulation, AI and conception; the effect of area was highly significant for the time of ovulation. Progesterone profiles showed that over 50% of the first post-partum ovarian cycles were short and had low progesterone concentrations. Season had significant effects on the length of the interval from calving to first post-partum ovulation, AI and conception, on the conception rate to first AI and consequently on the number of AIs per conception, and on the blood levels of glucose, urea and calcium.

    Objective: To investigate the relationship between enlargement of pituitary in postpartum females and the clinical biochemistry. Methods: In total 6 postpartum women were studied by MRI of pituitary and clinical biochemistry assessment, the data was collected especially in puerperium period. Results: Enlargement of pituitary gland was most remarkable in the first week of puerperium period, while endocrine changes including HCG, Progesterone, E 2 also reached considerable high peak in the same time especially the first and second day after labor. Prolactin also increased. βHCG, Progesterone, and E 2 rapidly decreased after the first week of puerperium period and the size of pituitary gland recovered to normal size. Conclusion: Postpartum enlargement of pituitary gland is physiological and related with internal environment change in gravitation, which is not to be misdiagnosed as a lesion

    A study was conducted to monitor reproductive of lactating Holstein Fries ian cows by measuring milk progesterone levels. Sequential post-partum milk samples were collected weekly throughout 20 weeks after pregnancy. Progesterone concentrations were determined by solid phase RIA. Lactating cows required an average of 5.2 weeks to resume luteal activity; 48% of the cows conceived after first insemination and had significantly high progesterone concentrations during the first 5 weeks after insemination than cows which returned to heat 5-8 weeks after insemination> Results also revealed that adequate level of progesterone, which varied between 4.2 and 9.1 nmol/l, is required to maintain early pregnancy and progesterone level remains high in pregnant cows.

    1997-04-01

    We recently reported that calcitonin gene-related peptide can reverse the hypertension produced by N(G)-nitro-L-arginine methyl ester in pregnant rats. In the current study we investigated whether these vasodilator effects of calcitonin gene-related peptide were progesterone dependent. Calcitonin gene-related peptide or N(G)-nitro-L-arginine methyl ester was infused through osmotic minipumps, either separately or in combination, to groups of five pregnant rats from day 17 of gestation until day 8 post partum or to nonpregnant ovariectomized rats for 8 days. Progesterone was injected during days 1 to 6 post partum and for 6 days after ovariectomy. Systolic blood pressure was measured daily. Animals receiving N(G)-nitro-L-arginine methyl ester exhibited significant elevations of blood pressure during pregnancy and post partum. Coadministration of calcitonin gene-related peptide to these rats reversed the hypertension during pregnancy but not during the postpartum period. At the dose used in this study calcitonin gene-related peptide administered alone was without significant effects on blood pressure. However, it reduced both the mortality and growth restriction of the fetus associated with N(G)-nitro-L-arginine methyl ester in these animals. Calcitonin gene-related peptide reversed the hypertension in N(G)-nitro-L-arginine methyl ester-infused postpartum rats during the periods of progesterone treatment only, and these effects were lost when progesterone treatment was stopped. Neither progesterone nor calcitonin gene-related peptide alone were effective. To further confirm these observations, progesterone effects were tested in ovariectomized adult rats. Similar to the findings in postpartum rats, calcitonin gene-related peptide completely reversed the elevation in blood pressure in N(G)-nitro-L-arginine methyl ester-treated rats receiving progesterone injections. The effects of calcitonin gene-related peptide were apparent only during the progesterone treatment

    In view of the reported cases of mood disorders that occur in mothers following childbirth and believing that sex steroid hormones contribute to mood and behavioral changes, this study has been aimed to explore the role of sex steroid hormones as an etiological factor for postpartum depression (PPD). This study was conducted at JIPMER, Puducherry, India between January 2010 and 2011. 103 women were recruited in the study after childbirth, out of which 62 women who were believed to be suffering from PPD were categorized as cases and the remaining 41 with no mood changes as controls, using Edinburgh Postpartum Depression Scale (EPDS) (cases had EPDS score ≥10 at 24-28h, controls had score postpartum). The hormones estimated in these two groups included estradiol, progesterone and testosterone, and their levels were compared between these two groups. A significantly high testosterone levels were observed in cases with PPD at 24-28h when compared to controls. Estradiol and progesterone levels did not show significant difference between cases and controls. ROC analysis done at 24-28h showed that testosterone levels beyond 42.71ng/mL predict the development of PPD with 79% sensitivity, 63% specificity, 68% positive predictive value, 74% negative predictive value with AUC being 0.708. This study shows that there is an association between persistent high serum testosterone level in women following childbirth and PPD. Copyright © 2015 Elsevier B.V. All rights reserved.

    Postpartum anoestrus is a serious cause of infertility in the swamp buffalo. Our studies have revealed that it is due to a failure in the resumption of ovarian cyclicity. Parity was inversely related to the calving interval being longer in primiparous than multiparous suckled buffaloes. This effect may be partly due to the higher nutrient demands for growth as well as for lactation in the primiparous animal. The effects of suckling on ovarian and pituitary function of postpartum buffaloes were investigated with the aid of radioimmunoassays for progesterone and luteinizing hormone (LH) as well as rectal palpation and laparoscopic inspection of the ovaries. The incidence of postpartum anoestrus was higher in suckled than non-suckled buffaloes. Weaning buffalo calves at 30 d postpartum resulted in the resumption of normal ovarian cycles within 60 d postpartum. LH release in response to a single injection of a synthetic gonadotropin-releasing hormone (GnRH) indicated that pituitary responsiveness to GnRH was restored by Day 30 postpartum in suckled buffaloes whereas anoestrous buffaloes were able to release levels of LH comparable to that of the preovulatory surge. A progesterone-releasing intra-vaginal device (PRID) induced an anovulatory oestrus in the anoestrous suckled buffalo which was partially overcome by human chorionic gonadotropin (HCG) administered at the induced oestrus. However, a 72 h separation of the calf from its dam combined with PRID was the most effective substitute to weaning in initiating ovarian cycles in the suckled buffalo. Our data suggest that suckling inhibits ovarian function not by an effect on the pituitary gland but rather on GnRH release by the hypothalamus. (author)

    This report covers three studies. In the first study, ovarian and oestrous activity were monitored in 47 buffaloes for 90 days following parturition. Failure to resume ovarian cyclicity after calving was found to be the main reason for the delay in conception. High incidence of ovulatory anoestrus (64%) constitutes also a major problem in Egyptian buffaloes. In the second study, buffaloes with inactive ovaries were treated at 90 days post-partum with either GnRH or progesterone, given either intravaginally (PRID) or orally (CAP). Both GnRH and PRID were effective in inducing ovulation but GnRH administration was followed by a high incidence of silent ovulation. Within the 35 days following treatment, about 50% of the PRID treated animals got in calf vs. 44 and 22% for GnRH and CAP treated animals, respectively. In the third study, buffaloes were treated with either 6 or 12μg GnRH at either 7 or 15 days post-partum. GnRH treatment resulted in significant reductions in the intervals from calving to first ovulation, first detected oestrus and time to first rise in serum progesterone concentration (> 1 ng/mL).

    Full Text Available Manual of Mental Disorders (DSM-IV, postpartum depression may include any nonpsychotic depressive disorder during the first four weeks of postpartum, according to research criteria during the first year after birth. The exact cause of postpartum depression is not yet known, and most researchers believe that postpartum depression is a bio-psycho-social problem. So far, the biological aspect of the disease is explained by changing the levels of estrogen and progesterone during pregnancy, and by decrease of hormone levels after birth. Psychological correlates are often associated with low selfesteem, pessimism as a personality trait, bad strategies of coping with stress, mood swings and emotional reactions. The social aspect of the disease is associated with the existential conditions of pregnant woman, support of partners and education level. This paper will include issues like hereditary causes and possible psychological factors of postpartum depression prevention. Nowadays, it is estimated that on average 15% of women, regardless of the pregnancy outcome, are suffering from postpartum depression. However, this information includes only those women who were diagnosed with postpartum depression and who themselves reported about it. Almost every woman receives basic care during pregnancy to prevent complications in the physiological level. This paper has shown possible psychological factors of postpartum depression prevention, the impact of optimism, self-esteem and coping skills.

    Modest increases of serum progesterone at human chorionic gonadotrophin (hCG) administration in controlled ovarian hyperstimulation (COH) cycles have been shown to have a negative impact on pregnancy outcomes. The aim of this study was to identify early predictors of progesterone elevation at hCG. Pregnancy outcome of 303 consecutive patients undergoing COH and fresh day-3 embryo transfer was analysed. Considering the non-linear relationship between progesterone at hCG triggering and pregnancy outcomes, partial area under the curve (pAUC) analysis was used to implement marker identification potential of receiver operating characteristic (ROC) curve analysis. Multivariate logistic analysis was then performed to identify predictors of progesterone rise. Pregnancy outcomes could be predicted by pAUC analysis (pAUC = 0.58, 95 % CI 0.51-0.66, p = 0.02) and a significant detrimental cut-off could be calculated (progesterone at hCG > 1.35 ng/ml). Total dose of rFSH administered, E2 level at hCG but mostly basal progesterone level (OR = 12.21, 95 % CI 1.82-81.70) were predictors of progesterone rise above the cut-off. Basal progesterone is shown to be the main prognostic factor for progesterone elevation. This observation should be taken into consideration in the clinical management of IVF/ICSI cycles to improve pregnancy outcomes.

    Dairy herds (472) in the northeastern United States of America were surveyed to evaluate reproductive performance. Error of oestrus detection (>> 1 ng/mL of milk progesterone) on the day of insemination was 5.1% for 4558 cows. 'Standing' and 'riding other cows' were the most accurate signs of oestrus. Of cows in or near oestrus when inseminated, 28.1% were open three weeks later, 12.9% were probably open, and 59% were probably pregnant according to milk progesterone analysis. Post-partum days to first insemination and conception rates showed positive correlation. Concentrations of progesterone in milk samples collected 21 to 24 days after service allowed prediction with 88.6% accuracy that a cow was pregnant and with 93.9% accuracy that she was not. By rectal palpation, veterinarians predicted with 92.5% accuracy that a cow was pregnant. (author). 12 refs, 4 tabs

    Since many dairy cows calve during late summer, the objective was to determine if heat stress immediately post-partum would (1) alter metabolism, thus, increasing susceptibility to metabolic disorders, (2) affect lactation and/or (3) affect reproduction. Forty four cows, calving during late summer, were paired with one member of each pair stressed (HS) for the first 10 post-partum days in a hot barn. Controls (CC) were kept in a cooled section of the barn. Plasma drawn weekly for 7 weeks was analyzed in an autoanalyzer for calcium, inor. phosphorus, protein, glucose and cholesterol and by radioimmunoassay for cortisol and progesterone. Ovaries and uteri were palpated weekly. Rectal temperatures were significant higher for HS during the first 10 post-partum days. No significant effects on plasma constituents were observed during the 10-day treatment period. For the 7-week period, glucose and cholesterol were lower in HS, as were cyclic peaks of progesterone and cortisol. Both calcium and inorganic phosphorus remained clinically low for the 7 weeks, but no treatment effects were seen. Uteri of HS involuted more rapidly than the CC. Treatment did not affect reproductive efficiency. Lactation milk yields did not differ, but milk fat percent was lower in HS. Heat stress immediately post-partum altered lipid metabolism, but the animal's compensatory mechanisms prevented reduction in milk production or reproductive efficiency.

    Progesterone withdrawal has been proposed as an underlying factor in premenstrual syndrome and postpartum depression. Progesterone withdrawal induces forced swim test (FST) immobility in mice, a depression-like behavior, but the contribution of specific receptors to this effect is unclear. The role of progesterone’s GABAA receptor-modulating metabolite allopregnanolone in depression- and anxiety-related behaviors has been extensively documented, but little attention has been paid to the role ...

    The artificial insemination (AI) has been widely applied for the rapid improvements of genetic and reproductive efficiency, especially in the developing countries. In Indonesia it was introduced for a long time ago, but the fertility rate of insemination cows, however, is still low. Due to the limitation or relying on visual observation and rectal palpation far determining reproductive status, monitoring milk progesterone can help to improve reproductive efficiency and economic benefits. To analyse progesterone concentration, milk samples were collected in vials containing sodium azide tablets.The milk samples were collected twice a week for about six weeks long, and stored at 4 o C in the refrigerator until analysed. Progesterone concentration in milk samples was determined by using solid phase radioimmunoassay (RIA) kit with 125 I labelled progesterone as tracer. The progesterone standards were prepared in skim milk and range from 0 to 40 nmol/I. The results of progesterone assay on samples of milk collected from five cows indicated that two cows with low progesterone, signifies that these cows had inactive ovaries (anoestrus), three other cows with post calving catalytic progesterone interpretation, and after subsequent insemination two cows getting pregnant. The accurate determination of progesterone levels can be used to confirm oestrus and diagnose non-pregnancy as well as to moriitor postpartum ovarian activity, early embryonic death and ovarian disorder

    We have previously established that the efficiency of identifying oestrus with activity-sensing devices can be compromised by common production diseases; the present study was undertaken to determine how these diseases may affect device readings. A total of 67 Holstein-Friesian cows, >20 days postpartum, were equipped with activity-sensing neck collars and pedometers, and simultaneous milk progesterone profiles were also monitored twice a week. The influences of common production stressors on maximum activity and progesterone values were analysed. Approximately 30% potential oestrus events (low progesterone value between two high values) remained unrecognised by both activity methods, and progesterone values in these animals were higher on the potential day of oestrus when both activity methods did not detect an event (0.043 ± 0.004 versus 0.029 ± 0.004 ng/mL; P = 0.03). Data from a subset of 45 cows (two events each) were subjected to mixed models and multiple regression modelling to investigate associations with production diseases. Cow motor activity was lower in lame cows. Maximum progesterone concentrations prior to oestrus increased as time postpartum and body condition score (BCS) increased. There were also fewer days of low progesterone prior to oestrus associated with increases in BCS and maximum progesterone concentrations prior to oestrus. In conclusion, lameness was associated with lower activity values, but this suppression was insufficient to account for lowered oestrus detection efficiency of either device. However, associations were identified between production diseases and progesterone profiles. Copyright © 2018. Published by Elsevier Inc.

    2017-10-01

    Autoimmune progesterone dermatitis is an uncommon disease presenting with cyclical skin eruptions corresponding with the menstrual cycle luteal phase. Because symptoms are precipitated by rising progesterone levels, treatment relies on hormone suppression. A 22-year-old nulligravid woman presented with symptoms mistaken for Stevens-Johnson syndrome. A cyclic recurrence of her symptoms was noted, and the diagnosis of autoimmune progesterone dermatitis was made by an intradermal progesterone challenge. After 48 months, she remained refractory to medical management and definitive surgical treatment with bilateral oophorectomy was performed. Autoimmune progesterone dermatitis is a challenging diagnosis owing to its rarity and variety of clinical presentations. Treatment centers on suppression of endogenous progesterone and avoidance of exogenous triggers. When these modalities fail, surgical management must be undertaken.

  14. Causes of postpartum anoestrus in cattle in the tropics

    Prolonged postpartum anoestrus is a major cause of economic losses in cattle in most tropical countries. The length of the period from parturition to first oestrus varies greatly in cattle in the tropics and is influenced by many factors, including endocrine events, management, nutrition, heat and humidity, genetic-environmental interactions, diseases and internal and external parasites. Results of recent research on endocrinology of the postpartum cow are particularly relevant to the problem in tropical cattle. Development of a pulsatile pattern of pituitary luteinizing hormone (LH) secretion is necessary for induction of the first postpartum oestrus, and many cows undergo a short episode of elevated plasma progesterone levels immediately before the first oestrus. Adrenal corticosteroids inhibit development of the pulsatile pattern of LH secretion. The concept is developed that elevated levels of cortisol, resulting from the stresses of heat, high humidity, malnutrition, parasites and diseases to which tropical cattle are often exposed, contribute to anoestrus. Techniques developed for oestrous cycle synchronization of cyclic cattle have been found to induce first oestrus and a fertile ovulation in a significant percentage of anoestrous lactating beef cattle. These treatments involve short-term (6-7 day) progesterone treatments, followed by single injections of prostaglandin Fsub(2α) and insemination 80 hours later. Some success has also been achieved in shortening the postpartum interval by pulsatile administration of gonadotropin-releasing hormone which, in turn, causes pulsatile release of LH, and by administering progestational compounds for short periods of time. Improved management, particularly oestrus detection and insemination at the optimum time, could contribute greatly to reducing the postpartum interval in tropical cattle. Nutritional factors that result in reduced haemoglobin levels (trace mineral deficiencies and parasite infestations) also cause

    Full Text Available Abstract Fertility records (n = 1 802 were collected from 615 Charolais primiparous and multiparous cows managed in an experimental herd over an 11-year period. The objectives of the study were to describe the genetic variability of the re-establishment of postpartum reproductive activity and the relationship with body weight (BW and body condition score (BCS at calving and age at puberty. The length of postpartum anoestrus was estimated based on weekly blood progesterone assays and on twice daily detection of oestrus behaviour. The first oestrus behaviour was observed 69 days (± 25 days s.d. post-calving and the first positive progesterone measurement (≥ 1 ng mL-1 was observed at 66 days (± 22 days s.d. for the group of easy-calving multiparous suckling cows. Estimates of heritability and repeatability were h2 = 0.12 and r = 0.38 respectively, for the interval from calving to first oestrus (ICO. Corresponding values were h2 = 0.35 and r = 0.60 for the interval from calving to the first positive progesterone test (ICP. The genetic correlation between both criteria was high (rg = 0.98. The genetic relationships between postpartum intervals and BW and BCS of the female at calving were negative: the genetic aptitude to be heavier at calving and to have high body reserves was related to shorter postpartum intervals. A favourable genetic correlation between age at puberty and postpartum intervals was found (rg between 0.45 and 0.70. The heifers which were genetically younger at puberty also had shorter postpartum intervals.

    Hormonal action has been implicated as a possible mechanism for pregnancy-induced analgesia. Previous investigators have reported an increase in heat pain tolerance during labor compared with nonpregnant controls and postulated it was because of the hormonal changes during pregnancy. However, these previous reports did not include measurement of hormonal values. The purpose of our study was to quantitatively test if changes in pregnancy hormone concentrations correlated with changes in temperature ratings. This was a prospective cohort study consisting of 32 women scheduled for elective cesarean delivery at term between July 2010 and January 2013. Heat pain threshold and tolerance, estrogen, progesterone, and oxytocin levels were measured twice in each patient at term and again 4 to 8 weeks postpartum. All hormone levels decreased significantly between term pregnancy and the postpartum visit (all P values heat pain measurements. The mean baseline heat pain threshold was 40.9°C at term compared with 40.3°C °postpartum (P = 0.47; mean change, -0.6°C; 95% confidence interval of change, -1.8°C to +0.7°C). The mean baseline heat pain tolerance was 46.1°C at term and 46.0°C postpartum (P = 0.59; mean change, -0.1°C; 95% confidence interval of change, -0.8°C° to +0.6°C). Our findings show that amounts of estradiol and progesterone changed significantly between the term and the postpartum visit; however, the thermal pain tolerance did not significantly change. In summary, we did not observe an association between hormonal changes and changes in pain threshold measures. This finding argues against the concept of simple progesterone- or estrogen-induced analgesia in humans.

    The main objective of this trial was to determine the post-partum ovaric activity in dairy cattle recently introduced in the Ecuadorian subtropic. On this trial, progesterone levels in milk of 114 post-partum cows from 6 different farms were determined. The progesterone level in milk was analyzed by RIA and the milk sampling was done according to established protocol. Additional data about management, nutritional condition and health of the animals were also taken in each farm. In the Santo Domingo valley, the ovaries of post-partum cows, with a good nutritious diet, start functioning after 54.21 days with a range of 10 to 161. The duration of the first oestral cycle was 24.07 with the range of 6 to 29 days. Fifty six cows (49.12 percent) remained pregnant up to the end of the trial and the average of interval calving was 409. 95 - 115. 69 days. In the area, there is high incidence of ovaric hypofunctions ( 30.70 percent) and return of anoestrus ( 14.03 percent). heats of the cows were observed ( 62.90 percent) by the farmers, but they were determined by progesterone levels, through RIA technique

    Full Text Available Serum progesterone and estradiol profiles during estrous cycle, gestation and parturition in four Dwarf goat females (Capra hircus were monitored. Blood sampling was carried out daily during estrous cycle and on alternate days during gestation till parturition. Observations regarding length of estrous cycle, gestation length, litter size and birth weight of kids were recorded. With the initiation of cyclicity, estradiol attained higher levels (7.7 ± 1.7 pg/ml at estrus phase and dropped down to the lower levels within 3 to 4 days post-estrus. Concomitantly, progesterone started to increase from the mean basal value of 0.1 ± 0.03 ng/ml on day-0 to 3.0 ± 0.9 ng/ml on day-6 of estrous cycle and reached the peak value of 7.7 ± 0.6 ng/ml on day-12. From day-15, a decline was observed in progesterone values till the end of the cycle. A second estradiol rise of 14.0 ± 1.2pg/ml was observed on day-18 of the cycle. The mean estrous cycle length was 18.2 ± 2.1 days. During gestation, higher progesterone levels were maintained in the range of 4.3–11.0 ng/ml. Estradiol remained at lower concentrations for 30-50 days of gestation, then gradually increased and reached 270 ± 13.0 pg/ml a few days before parturition. It dropped again to basal values within 1-2 days postpartum. The mean gestation length in Dwarf goats was 144.8 ± 3.9 days and the litter size was 1.8 ± 0.5. It was concluded that Dwarf goat is a prolific breed, having a short gestation length with multiple births being common.

    Full Text Available Abstract Background In pregnant rats, structural luteal regression takes place after parturition and is associated with cell death by apoptosis. We have recently shown that the hormonal environment is responsible for the fate of the corpora lutea (CL. Changing the levels of circulating hormones in post-partum rats, either by injecting androgen, progesterone, or by allowing dams to suckle, was coupled with a delay in the onset of apoptosis in the CL. The objectives of the present investigation were: i to examine the effect of exogenous estradiol on apoptosis of the rat CL during post-partum luteal regression; and ii to evaluate the post-partum luteal expression of the estrogen receptor (ER genes. Methods In a first experiment, rats after parturition were separated from their pups and injected daily with vehicle or estradiol benzoate for 4 days. On day 4 post-partum, animals were sacrificed, blood samples were taken to determine serum concentrations of hormones, and the ovaries were isolated to study apoptosis in situ. In a second experiment, non-lactating rats after parturition received vehicle, estradiol benzoate or estradiol benzoate plus bromoergocryptine for 4 days, and their CL were isolated and used to study apoptosis ex vivo. In a third experiment, we obtained CL from rats on day 15 of pregnancy and from non-lactating rats on day 4 post-partum, and studied the expression of the messenger RNAs (mRNAs encoding the ERalpha and ERbeta genes. Results Exogenous administration of estradiol benzoate induced an increase in the number of apoptotic cells within the CL on day 4 post-partum when compared with animals receiving vehicle alone. Animals treated with the estrogen had higher serum prolactin and progesterone concentrations, with no changes in serum androstenedione. Administration of bromoergocryptine blocked the increase in serum prolactin and progesterone concentrations, and DNA fragmentation induced by the estrogen treatment. ERalpha and

    The plasma progesterone profile of six cycling and three pregnant Nellore ewes was estimated by radioimmunoassay. The progesterone level of cycling ewes started rising from undetectable level on the day of oestrus to a mean peak value of 0.41 ± 0.09ng/ml during post oestrus day 10 to 14 and then declined to undetectable levels 1 to 2 days before subsequent oestrus. But the progesterone levels of pregnant ewes exhibited further raise from the post oestrus day 14 to the day 40. However, no correlation between oestrous cycle length and the total progesterone produced during the oestrous cycle was observed. (author). 9 refs., 2 figs

    Reduced fertility of dairy cows during periods of elevated temperature, humidity, or both might be associated with low plasma progesterone concentration. Alleviation of thermal stress by efficient cooling is a prerequisite for improving fertility by hormonal treatment. We examined whether insertion of a controlled intravaginal drug-releasing (CIDR) insert containing progesterone following artificial insemination (AI) would improve summer conception rate. Control (n = 195) and treated (CIDR; n=165) cows, yielding on average 42.3 kg milk/d, were inseminated following estrus detection during the summer (July to October) in 2 commercial dairy herds in Israel. Mean maximal air temperature and relative humidity during the study were 30.2°C and 86%, respectively. All experimental cows were efficiently cooled throughout the study, as confirmed by measuring the body temperature of random cows. Treated cows received a CIDR insert on d 5 ± 1 post-AI for 13 d and pregnancy was confirmed by palpation 45 d post-AI. Plasma progesterone concentration in treated cows was elevated by approximately 1.5 ng/mL. Multiple logistic regressions were used to analyze conception rate. Treatment did not alter the overall conception rate; however, probability of conception increased in CIDR-treated cows with low body condition score (BCS) compared with their control counterparts (53 vs. 27%, respectively). A pronounced increase in probability of conception was recorded in CIDR-treated cows exhibiting both low BCS and postpartum reproductive disorders, compared with their control counterparts (58 vs. 14%, respectively). Exogenous progesterone supplementation on d 5 post-AI for 13 d improves summer fertility of subpopulations of cows exhibiting low BCS and postpartum reproductive disorders. Reproductive management based on specific hormonal treatment of designated subgroups of cows known to derive beneficial effects from it might improve treatment efficiency and reduce expenses.

    Post-partum ovarian activity in Alentejano beef cows maintained on natural pastures was monitored by measuring plasma progesterone levels using the radioimmunoassay method. Post-partum anoestrus was compared in cows calving in two different seasons (winter and summer). Differences between primiparous and multiparous cows, the effect of short term nursing interruption (72 hours by the 20th day post-partum) and the dam's body weight at calving (BWC) were also considered with respect to their influence on the onset of post-partum ovarian activity. Fertility after two breeding seasons of natural mating (April-May) and November-December) was also studied. Post-partum anoestrus was significantly longer in winter calving cows than in those calving in summer, in both multiparous and primiparous cows (73.9 versus 33.1 and 111.1 versus 35.6 days, respectively; P 2 =0.41; P<0.03). Because of a longer post-partum anoestrus, fertility was reduced in cows calving during the winter season compared with those calving in summer in all three years of the study (63.9 versus 76.9%, 57.8 versus 62.9% and 36.5 versus 60.6%, for 1984, 1985 and 1986, respectively). The results presented show that the winter period in Portugal impairs the return to ovarian activity post-partum in this breed. 19 refs, 2 figs, 4 tabs

In the first study 90 post-partum cows at three locations (Surabaya, Grati and Puspo) were used to investigate post-partum ovarian function. The highest incidence of cows not showing oestrus up to 80 days post-partum, with progesterone profiles less than 0.75 ng/mL, was found in Puspo (63.3%), compared with 10% in Surabaya and 20% in Grati. The incidence of cows with silent heat and oestrus without ovulation was 13.3 and 3.3% in Surabaya, 16.7 and 6.7% in Grati, and 23.3 and 0% in Puspo. There was no significant difference (P>0.05) between the lengths of oestrous cycles at the three different locations. In the second study, using 120 cows for investigating confirmation of oestrus at AI, 69.7% of cows inseminated during the follicular phase had become pregnant, compared with 16.1% of cows inseminated during the luteal phase. The incidence of long luteal phases which included embryonic death was 13.4%. The accuracy of pregnancy diagnosis based on progesterone concentrations at day 22 was 77% and was lower than that at day 29 (88%). In the third study, cows in Subgroups 3A and 3B had cystic ovaries and were treated with prostaglandin F 2α by either intramuscular (3A) or intrauterine (3B) routes. Pregnancy rates were 50 and 40%, respectively. Cows in Subgroups 3C, 3D and 3E had inactive ovaries and were treated with intravaginal application of MPA sponges (3C), PRID (3D) or PRID followed by LH injection (3E). The pregnancy rates were 30, 40 and 60%, respectively. (author). 10 refs, 6 tabs

    Milk progesterone profiles in Chengdu Mah (CM), Saanen (S) and crossbred (CM x S, F1) goats were determined using radioimmunoassay throughout the period from kidding to the beginning of the next breeding season. Different patterns of progesterone profiles were recorded in these does. When milk progesterone concentrations were elevated above 6 ng/mL for at least 6 days they were regarded as signs of ovarian activity. The frequencies of such rises during anoestrus were 4.0, 1.8 and 2.5 per animal in CM, S and F1 goats respectively. The frequencies of progesterone rise were higher than that of behavioural oestrus in the does. After exposing the does to the buck three times during the anoestrus period, no significant 'male effect' was observed on the milk progesterone level or behavioural oestrus during the first six months after kidding. The male effect on behavioural oestrus became apparent only in the seventh month after kidding, while milk progesterone levels did not change markedly compared with those of the control does.

    To ascertain the association between basal progesterone (P) levels and the occurrence of preovulatory progesterone rise (PPR) and clinical pregnancy rates (CPRs) in ICSI cycles with GnRH antagonists. Serum P levels of 464 patients were measured on day 2 and day of hCG of cycles. Cycles with basal P levels>1.6ng/mL were cancelled. All embryos were cryopreserved in cycles with P levels≥2ng/mL on the day of hCG. The primary outcome measures were the incidence of PPR (P>1.5ng/mL) and CPR with regard to basal P. Basal P levels were significantly higher in cycles with PPR than in those without PPR (0.63±0.31 vs. 0.48±0.28ng/mL). Area under the curve for basal P according to ROC analysis to discriminate between elevated and normal P levels on the day of hCG was 0.65 (0.58-0.71 95% CI, pcycles with and without PPR was 0.65ng/mL. Cycles with basal P levels above 0.65ng/mL had a significantly higher incidence of PPR (30.9% vs. 13.5%) but similar clinical and cumulative pregnancy rates (38.8% vs. 31.1% and 41.7% vs. 32.6%, respectively) in comparison to cycles with basal P levels below 0.65ng/mL. In multivariate regression analysis, basal P levels, LH level on the first day of antagonist administration, and estradiol levels on the day of hCG trigger were the variables that predicted PPR. Basal P levels were associated with increased incidence of PPR but not with CPR. Copyright © 2017 Elsevier B.V. All rights reserved.

    Cross-bred dairy cows (n=202) were used to study the milk progesterone profiles 0, 5, 7, 12, 20, 28, 35 and 45 days after artificial insemination. It was found that 57% (115/202) of the cows had a normal oestrous cycle and conceived, but in 13% (15/115) of cows that conceived the embryos died between 28 and 35 days of gestation. A total of 43% (87/202) of the cows did not become pregnant and these could be classified into four groups: 15% (31/202) had normal oestrous cycles; 7% (15/202) were inseminated during the luteal phase, i.e. when progesterone concentrations were elevated; 14% (29/202) had irregular cycles; and 6% (12/202) were acyclic. In another study milk samples were collected every 3 days from 90 cross-bred dairy cows, commencing 15 days after parturition and continuing until each animal had been inseminated. The milk progesterone profiles of each cow were collated with the records of oestrus and insemination. The average post-partum anoestrous periods of primiparous and multiparous cows were 35.0 ± 16.4 and 34.9 ± 14.5 days, respectively. In 68% of the primiparous cows and 65% of the multiparous cows oestrus occurred between days 20 and 40 of the post-partum period. Sequential serum samples from 42 repeat breeder cows and 8 infertile heifers were analysed for progesterone, and their ovaries were examined weekly by rectal palpation. They were treated with either human chorionic gonadotrophin (HCG), pregnant mare serum gonadotrophin (PMSG) or prostaglandin F 2α . As a result, 23 cows and 5 heifers re-established oestrous cycles and became pregnant after AI. Progesterone profiles and rectal palpation revealed various causes of infertility, including ovarian cysts, irregular oestrous cycles, inactive ovaries and abnormal oviducts. Fifty-six per cent of repeat breeder cows and infertile heifers responded to hormone treatment in terms of resumed ovarian function. (author). 14 refs, 6 figs, 3 tabs

    A technique for the radioimmunoassay of progesterone in plasma is described. In one trial the oestrous cycles of four cycling cows and in another trial of one non-cycling cow and two cycling heifers were synchronized by the administration of progesterone. Each female received either 50 mg or 0,1 mg/kg of progesterone intramuscularly on alternate days in two courses of four and six injections respectively. Blood samples of the animals were collected either daily or two-daily before, over the entire period of treatment and for eight days after the last progesterone injection. The results of the progesterone assays are represented graphically for each individual cow or heifer. The plasma progesterone levels during treatment were maintained reasonably well at levels corresponding to those normally encountered during the luteal phase of the cycle. The progesterone levels, however, did not drop as rapidly as desired after the last injection but might have been influenced by a residual corpus luteum from a previous ovulation

    Electrical resistance (ohms) of mucus were analyzed in 20 postpartum Holstein cows by use of a probe inserted into the anterior vagina every other day for 30 days. Composite milk samples were taken on the same day, and progesterone was determined by radioimmunoassay. Cows were observed twice daily for standing estrus and reproductive organs palpated weekly per rectum (rectal palpation). Fifteen cows which were cycling showed increasing progesterone 6 to 7 days after the onset of estrus with values of 8.1 to 10.0 ng progesterone/ml milk on days 10 to 17. Concentrations had declined rapidly 2 days before onset of the next estrus. Progesterone in milk was affected by cow and by day of the cycle. Electrical resistance followed a similar cyclical pattern, but variability was large and only cows differed. The correlation between milk progesterone and mucus resistance was .22. Progesterone concentrations for four cows with follicular cysts fluctuated randomly with a mean of 2.6 ng/ml. Mean resistance of vaginal mucus was 44 omega for both cycling and cystic cows, indicating that a single measurement of electrical resistance every 2nd day was unreliable in distinguishing physiological states. One cow had high progesterone in milk on days 19 to 25 and was diagnosed pregnant by rectal palpation 3 wk later. Cows were not seen in estrus 28% of the time when milk progesterone and rectal palpation indicated they were in the follicular phase of the estrous cycle and were cycling.

    Progesterone (P 4 ) levels in skin milk were determined in two groups of dual purpose cows from farms in the Department of Escuintla on the south coast of Guatemala. Fifteen adult cows (crosses of Criollo with Zebu and Brown Swiss) were selected on the first farm and ten first-calf heifers (crosses of Criollo with Zebu and Holstein) on the second; both groups were considered to be representative of dual purpose livestock (milk and meat producers) in the country. To study the resumption of ovarian activity post-partum, milk samples were taken once a week from 10 days after calving until the first natural service; thereafter, sampling continued twice-weekly for 60 more days when the animals were rectally palpated for pregnancy diagnosis. On farm 1, the mean interval from calving to first rise in P 4 levels indicative of ovarian function was 42±16.7 days; all the study cows were at third calving and resumed cyclicity. On farm 2, only 30% of the study heifers resumed cyclicity and these had an interval from calving to first rise in P 4 of 80±28.9 days; all were at first calving. On farm 1, 73% of cows were served during first oestrus, 13% at second oestrus and 13% at the third. On farm 2, only 30% (3/10) of cows were served at first oestrus; the other 70% did not show signs of ovarian activity during the trial period which lasted until day 129 post-partum. Palpation of the cows 60 days post-service showed that all cows had conceived on farm 1 but only 20% on farm 2. (author). 9 refs, 3 figs

    This publication summarizes the principal application of P 4-RIA of blood which helped to determine the time for onset of sexual functions after parturition, the incidence of silent oestrus, and the correct timing of service. Progesterone profiles showed that cows in this herd ovulated considerably later than 35+/-7 days after calving, which is the value reported for many other herds of dairy cows. The percentage of cows in oestrus was found 66% within 60 days post-partum while the incidence of silent oestrus was 20%. The correct timing of service is 85%. According to this study, the major causes for the lowered reproductive efficiency in this herd were found to be the delayed onset of post-partum ovarian activity and the incidence of silent oestrus. 9 refs. 3 tabs

    Full Text Available Aim: The study was conducted to determine the serum levels of certain hormones in post-partum anestrus cows following treatment with controlled internal drug release (CIDR and Ovsynch protocol. Materials and Methods: A total of 30 postpartum anestrus cows were divided into three equal groups after thorough gynecoclinical examination. The Group 1 animals received an intravaginal progesterone device on day 0 and 2 ml of prostaglandin F2α (PGF2α on day of CIDR removal (7th day, Group 2 cows were treated with ovsynch protocol (gonadotropinreleasing hormone [GnRH]-PGF2α-GnRH on day 0, 7 and 9, respectively, and Group 3 cows were supplemented with mineral mixture and treated as control. The serum estrogen, progesterone, triiodothyronine, and thyroxine concentration were estimated using enzyme-linked immunosorbent assay kit and absorbance was read at 450 nm with Perkin Elmer Wallac 1420 Microplate Reader. Results: There was a significant increase in progesterone level in Group 1 after withdrawal of CIDR as compared to other two groups. However, the estrogen assay revealed a greater concentration in Group 2 against Group 1 on day 7 of sampling. However, there was no significant difference for serum triiodothyronine (T3 and thyroxine (T4 irrespective of treatment protocols and days of sampling. Conclusion: Treatment with CIDR based progesterone therapy and drug combinations may affect the reproductive hormonal balance like estrogen and progesterone, which is inevitable for successful return to cyclicity and subsequent fertilization and conception. However, as far as serum T3 and T4 concentration concerned it may not give an astounding result.

    Optimal body condition in early lactation is generally accepted as a prerequisite for good reproductive performance. Examination of milk progesterone profiles offers an objective method for characterization of postpartum ovarian activity in dairy cows. The present study investigated the relationship between body condition after calving, some metabolic parameters in blood plasma, and fertility, as reflected by milk progesterone profiles in the two dairy breeds Swedish Red (SR) and Swedish Holstein (SH). Multiparous dairy cows (n = 73) of SR and SH breeds were selected and divided into three groups based on their body condition score (BCS) after parturition. Selected plasma metabolites were determined, milk progesterone profiles were identified and body condition was scored. Over-conditioned cows and atypical progesterone profiles were more common among SR cows. Insulin sensitivity was lower and IGF 1 higher among SR cows. Insulin was positively related to body condition, but not related to breed. Atypical progesterone profiles were more common and insulin sensitivity lower in SR than in SH cows, but the SR breed had a higher proportion of over-conditioned SR cows. It is reasonable to assume that breed differences in body condition contributed to these results.

    Full Text Available A 2-sample regime was used to measure whole milk progesterone concentration on the day of oestrus and insemination (Day 0 and 6 days later (Day 6 in a sample of 50 primiparous and 100 multiparous suckling beef cows. Exposure to teaser bulls and observation by cattlemen identified the occurrence of oestrus. Three sets of criteria used to define ovulatory oestrus were compared : a milk progesterone concentration less than 6 nmol / l on Day 0 ; b milk progesterone less than 6 nmol / l on Day 0 and rising to greater than 6 nmol / l on Day 6; c milk progesterone less than 6 nmol / l on Day 0 and rising to greater than 6 nmol / l on Day 6, or cow diagnosed pregnant to 1st insemination. Using only a single milk sample on Day 0 (criterion a would have resulted in the positive predictive value of heat detection being estimated at 98.7%. Using a paired measurement (criterion b resulted in a significantly lower estimate of 84.7%. The inclusion of cows that conceived despite not showing a marked rise in milk progesterone concentration (criterion c resulted in a more accurate estimate of 89.3%. Use of a 2-sample regime also allowed calculation of conception rates while eliminating the effect of heat detection errors. In the cows sampled, of those in ovulatory oestrus that were inseminated, 73.1% conceived to the 1st insemination. These results demonstrate that artificial insemination within a limited breeding season can be successful if nutrition is optimal and management is intensive. The use of a 2-sample milk progesterone test may be a valuable tool in investigating heat detection and conception problems in beef herds in which artificial insemination is used.

  19. Emotion Reactivity Is Increased 4-6 Weeks Postpartum in Healthy Women: A Longitudinal fMRI Study.

    Directory of Open Access Journals (Sweden)

    Malin Gingnell

    Full Text Available Marked endocrine alterations occur after delivery. Most women cope well with these changes, but the postpartum period is associated with an increased risk of depressive episodes. Previous studies of emotion processing have focused on maternal-infant bonding or postpartum depression (PPD, and longitudinal studies of the neural correlates of emotion processing throughout the postpartum period in healthy women are lacking. In this study, 13 women, without signs of post partum depression, underwent fMRI with an emotional face matching task and completed the MADRS-S, STAI-S, and EPDS within 48 h (early postpartum and 4-6 weeks after delivery (late postpartum. Also, data from a previous study including 15 naturally cycling controls assessed in the luteal and follicular phase of the menstrual cycle was used. Women had lower reactivity in insula, middle frontal gyrus (MFG, and inferior frontal gyrus (IFG in the early as compared to the late postpartum assessment. Insular reactivity was positively correlated with anxiety in the early postpartum period and with depressive symptoms late postpartum. Reactivity in insula and IFG were greater in postpartum women than in non-pregnant control subjects. Brain reactivity was not correlated with serum estradiol or progesterone levels. Increased reactivity in the insula, IFG, and MFG may reflect normal postpartum adaptation, but correlation with self-rated symptoms of depression and anxiety in these otherwise healthy postpartum women, may also suggest that these changes place susceptible women at increased risk of PPD. These findings contribute to our understanding of the neurobiological aspects of the postpartum period, which might shed light on the mechanisms underlying affective puerperal disorders, such as PPD.

      Although progesterone vaginal suppositories (hospital-formulated) are used for the treatment of infertility, their half-life is so short that multiple doses are required. In this study, we aimed to develop sustained-release vaginal suppositories suitable for clinical use which maintain an effective blood concentration by once-a-day treatment, and prepared 7 types of suppository containing the sustained-release progesterone tablets to characterize their sustained-release performance. We selected one candidate suppository among them, taking recovery rate, reproducibility, and hardness, as well as the sustained-release performance into consideration. The shell of the selected suppository is composed of VOSCO S-55 and progesterone for rapid release. The molded progesterone tablets for sustained release were embedded inside. The distribution of the weight and content of the suppository was limited, and the release rate of progesterone was significantly slower than that of a conventional progesterone suppository prepared in our hospital. The single-dose administration of the selected suppository to five healthy volunteers led to significant extension of the blood concentration. We also confirmed the rise of the basic value by multiple administration. The simulation comparison suggested that the blood progesterone concentration is controlled by once-a-day administration of the selected suppository better than twice-a-day administration of the conventional suppository. In conclusion, the sustained-release vaginal suppository prepared in this study was considered to be useful for clinical treatment.

    2017-01-01

    Full Text Available Postpartum depression affects 15% of women. Channa striatus, a freshwater fish, is consumed in local Malay population as a rejuvenating diet during postpartum period. This study evaluated the antidepressant-like effect of lipid extract of C. striatus fillet and its mechanism of action in female Sprague-Dawley rats in postpartum model of depression. The rats were ovariectomized and treated with high dose of progesterone and estradiol benzoate for 23 days to have hormone-simulated pregnancy. The day 24 and afterwards were considered as the postpartum period. During the postpartum period, lipid extract was administered at 125, 250, and 500 mg/kg through intraperitoneal route for 15 days. Fluoxetine (10 mg/kg was used as the positive control. On postpartum day 15, the animals were tested in forced swimming test (FST and open field test (OFT followed by biochemical analysis. Withdrawal of hormone administration during the postpartum period induced depressive-like behavior in FST. Administration of lipid extract reversed that depressive-like behavior at 125, 250, and 500 mg/kg in FST. In OFT, it decreased the exploratory activity. The mechanism of the antidepressant-like effect may be mediated through the decrease in plasma corticosterone, increase in plasma oxytocin, and decrease in nuclear factor-kappa B in prefrontal cortex of rats.

    Resumption of luteal activity postpartum and fertility were investigated in an Estonian Holstein high milk production and good fertility dairy herd. Body condition was scored after every 10 days in 54 multiparous dairy cows (71 lactations) calving inside from December to March during 4-year period. Blood samples were taken 1-14 days before calving and 1-14, 28-42 and 63-77 days after calving: analytes estimated were serum aspartate aminotransferase (AST), glucose, ketone bodies, total cholesterol, non-esterified fatty acids and triglycerides. The general linear mixed model was used to compare the data for cows with different characteristics in luteal activity postpartum based on their milk progesterone profiles. Forty-five per cent of cases had abnormal profiles; delayed resumption of ovarian cyclicity postpartum (DC) was the most prevalent abnormality. There was no difference in body condition scores between the groups. The DC and prolonged luteal phase groups had higher serum AST activity (p fertility.

    The objective was to determine the effect of plasma progesterone concentration and the duration of proestrus during growth of the ovulatory follicle on fertility in beef cattle. Heifers (N = 61) and postpartum cows (N = 79) were assigned randomly to four groups in a two-by-two design involving luteal-phase versus subluteal-phase plasma progesterone concentrations and normal versus short proestrus. To synchronize follicular wave emergence, estradiol-17β was given im during the midluteal phase (Day 0) and concurrently, a once-used controlled intravaginal progesterone-releasing device was placed intravaginally. In the subluteal-phase progesterone groups, a luteolytic dose of PGF(2α) was given on Day 0 and again 12 hours later. In the luteal-phase progesterone groups, PGF(2α) was not given (so as to retain a functional CL). The controlled intravaginal progesterone-releasing device was removed and PGF(2α) was given on Days 7 or 8 in the normal- and short-proestrus groups, respectively. Cattle were given lutropin im 12 or 36 hours later in the short- and normal-proestrus groups, respectively, with AI at 12 hours after lutropin treatment. Transrectal ultrasonography was used to monitor ovarian response during treatments and to diagnose pregnancy 60 days after AI. Cattle (heifers and cows combined) in the subluteal-phase progesterone groups and normal proestrus groups had a larger follicle at the time of AI, and a larger CL that secreted more progesterone 9 days after AI than cattle with luteal-phase progesterone concentrations or those with short proestrus (P < 0.03). There was a higher incidence of ovulation (P < 0.01) the day after AI in heifers (55/61; 90%) than in cows (44/79; 56%). Pregnancy rates ranged from 11% to 54%, and were higher in cattle (heifers and cows combined) in the subluteal-phase progesterone groups and normal proestrus groups than in the luteal-phase progesterone or short proestrus groups, respectively, (P < 0.02). In conclusion, a short

    Post-partum ovarian activity was studied by means of rectal palpation, and progesterone (P 4 ) concentration measured by radioimmunoassay in defatted milk samples in Jersey, Holstein, Criollo and Criollo x Jersey cows. The accuracy with which farm personnel detected oestrus was monitored from measurements of P 4 on the day of AI and 23 days later. P 4 profiles during the oestrous cycle and early pregnancy were determined in Jersey cows through the analysis of daily milk samples. Accuracy of pregnancy diagnosis as indicated by P 4 levels was 79% and 88% in Jersey and Holstein cows respectively. Diagnosis of non-pregnancy from P 4 levels was found to be 100% accurate. Only 62% of the Jerseys and 82.5% of the Holsteins which returned to oestrus after first AI post-partum were identified by staff on the different farms. Studies carried out in Jersey and Holstein cows during the early post-partum period revealed significant discrepancies between P 4 levels and palpable corpora lutea. P 4 profiles showed the presence of short (< 14 days) oestrous cycles in 53.9% and 47.4% of the Jersey and Holstein cows respectively during the first six weeks post-partum. Cows which developed milk fever at or before calving but which were treated promptly took no longer than healthy cows to resume ovarian activity. However, compared with healthy cows, those which had dystocia, retention of placenta or severe metritis took significantly longer (P < 0.01) to resume ovarian activity. Studies in the humid tropics during the post-partum period in Criollo, Criollo x Jersey and Jersey cows showed that 57% of the animals exhibited pre-ovulatory short cycles. Analysis of the monthly AI percentages in the different genetic groups indicated a seasonal distribution in sexual receptivity in both Criollo and Jersey dairy cows under these conditions; Criollo cows also resumed post-partum ovarian activity sooner than the other breeds.

    Endometriosis is a common cause of pelvic pain and affects up to 10% of women of reproductive age. Aberrant progesterone signaling in the endometrium plays a significant role in impaired decidualization and establishment of ectopic endometrial implants. Eutopic endometrial cells from women...... with endometriosis fail to downregulate genes needed for decidualization, such as those involved in cell cycle regulation, leading to unbridled proliferation. Several causes of progesterone resistance in the endometrium have been postulated, including congenital "preconditioning", whereby the in utero environment...... renders infants susceptible to neonatal uterine bleeding and endometriosis. Progesterone action is crucial to decreasing inflammation in the endometrium, and deviant progesterone signaling results in a proinflammatory phenotype. Conversely, chronic inflammation can induce a progesterone resistant state...

    The aims of the present study were to initially determine the pattern of serum adiponectin concentrations during a normal estrous cycle in high-producing postpartum dairy cows and then evaluate the relationship between the serum concentrations of adiponectin and insulin with the commencement of postpartum luteal activity and ovarian activities in clinically healthy high-producing Holstein dairy cows. During a normal estrous cycle of cows (n = 6), serum adiponectin concentrations gradually decreased (P Cows with higher peak of milk yield had lower serum adiponectin concentrations by week 7 postpartum (P = 0.01). Serum adiponectin and insulin concentrations in cows with different postpartum luteal activity (based on the progesterone profile) were evaluated using the following class of cows: normal (≤45 days, n = 11) and delayed (>45 days, n = 11) commencement of luteal activity (C-LA) and four different profiles of normal luteal activity (NLA, n = 5), prolonged luteal phase (n = 6), delayed first ovulation (n = 6), and anovulation (AOV, n = 5). Serum adiponectin concentrations decreased gradually by week 3 postpartum in NLA and then increased; whereas in AOV and delayed first ovulation, they were decreased after week 3 postpartum (P cows was more than that of NLA cows. Insulin concentrations were almost maintained at a stable level in NLA cows (P > 0.05), whereas they increased in the other groups (P cows with C-LA greater than 45 days decreased more than those with C-LA 45 days or less after week 3 postpartum (P = 0.002). Serum adiponectin concentrations at week 7 postpartum were lower in delayed C-LA (P = 0.01). Milk yield in cows with C-LA greater than 45 days increased more than cows with C-LA 45 days or less postpartum (P = 0.002). Insulin concentrations increased relatively in parallel from weeks 1 to 7 postpartum in cows either with C-LA greater than 45 or with C-LA 45 days or less. We showed for the first time the profile of serum adiponectin concentrations

    Levels of LH, FSH, and progesterone in serum were measured in lactating hamsters and in hamsters in which acyclicity was induced with altered photoperiod. Lactating hamsters were found to have low titers of LH, FSH, and progesterone in serum at 0900 (lights on 0500--1900) on Days 4, 9, 14, and 19 of lactation and increased levels of these hormones at 1600. Levels of LH and FSH in serum at both 0900 and 1600 remained relatively constant throughout lactation. In contrast, levels of progesterone in serum obtained at both 0900 and 1600 sampling times increased as lactation progressed. Ovariectomy on Day 9 of lactation reduced serum levels of progesterone at both 0900 and 1600 and eliminated the afternoon surge in progesterone in animals bled 5 days after surgery. The levels and pattern of LH in serum remained unchanged after ovariectomy in lactating hamsters. However, serum FSH levels in the ovariectomized, lactating animals were elevated at both 0900 and 1600 when compared to levels present in intact, lactating hamsters bled at the same times. Females which were acyclic due to altered photoperiod displayed similar patterns of LH, FSH, and progesterone in serum. Levels of LH, FSH, and progesterone in serum were low at 1000 (lights on 0500--1500) and were increased 2 to 10 fold at 1500. Ovariectomy was followed by lower progesterone levels in serum at 1000 and 1500 and eliminated the afternoon rise of this hormone. Serum levels of LH were unaffected by ovariectomy. As in lactating hamsters, levels of FSH in serum were elevated 3--4 days following ovariectomy at both bleeding times, but the levels were higher at 1500. These results indicate that acyclicity induced by lactation or exposure to a short photoperiod is characterized by similar diurnal patterns of circulating hormones in the hamster

    The objective of this study was to evaluate the effect of an extended progesterone treatment on follicular development and fertility in postpartum, suckled beef cows subjected to timed artificial insemination (TAI). In experiment 1, cows (n = 24) with body condition score (BCS) ≥4.5 received either a 2-g progesterone intravaginal device on Day -23 or a 0.558-g progesterone intravaginal device on Day -9. Then, all cows received 2 mg of estradiol benzoate on Day -9; removal of the device, 1-mg estradiol cypionate, and PGF2α on Day -2; and TAI on Day 0. Metabolic status was assessed between Days -9 and -2. Ovarian structures and plasma progesterone were determined weekly from Day -23 to -9, daily from Day -9 to 0, and weekly until Day 28. In experiment 2, cows (n = 302) with BCS ≥4.5 received identical treatment to cows in experiment 1, but on Day -2, cows received 400 IU of two different commercial preparations of equine chorionic gonadotropin (eCG). Ovarian structures were determined on Days -23 and -9 on a subset of cows (n = 40). Pregnancy was determined 39 days after TAI. In experiment 3, multiparous cows (n = 244) with BCS cows in experiment 1 initiated on Day -18, and on Day -2, cows received 400 IU of eCG or no treatment. Ovarian structures were determined in a subset of cows (n = 31) on Days -3, -2, -1, 0, 1, and on Day 10. Pregnancy was determined 39 days after TAI. The results indicated that in experiment 1, plasma progesterone was higher in treated than nontreated (control cows) during the first 14 days (P = 0.0001). The extended progesterone treatment increased the size of the largest follicle between Days -23 and Day -5 (Group by Day, P = 0.04) and tended to increase the size of the dominant follicle from Day -5 to Day -1 (Group by Day, P = 0.06). There was no effect of metabolic status or interaction between metabolic status and day on follicular growth. In experiment 2, extended progesterone treatment tended to increase the

    The study was carried out on five dairy herds in the North-East Poland. The cows, which showed no visible oestrus signs until day 60 postpartum, were examined by ultrasonography and rectal palpation twice, at a 10-d interval. A real-time, B-mode scanner with a 5 MHz probe was used. The plasma progesterone concentration was determined using RIA. A high progesterone level on the first examination, but low on the second, or low on the first and high on the second examination were interpreted as a silent heat. Based on the progesterone values, silent heat was diagnosed in 145 anoestrous cows, whereas ultrasonographically, 106 cows were found to have silent heat. The accuracy of the ultrasonography and rectal palpation in the diagnosis of silent heat in cows was 89.0 % and 69.7 %, respectively (P ≤ 0.05). For the diagnosis of the corpus luteum, the sensitivity and specificity of the ultrasonography was 94.7 % and 84.0 %, and for rectal palpation 86.2 % and 70.3 %, respectively (P ≤ 0.05). Our results showed that ultrasonography is a useful tool in the diagnosis of silent heat in cows. (authors)

    In order to monitor ovarian activity in post-partum dairy cows in the Cayambe Valley, Ecuador, 164 cows from three farms were studied. Milk progesterone concentrations (analysed by RIA) and additional data on livestock management, nutritional status and health were compiled. Farms were classified mainly according to nutritional and management status; the better the nutritional status of the cows the sooner they resumed oestrous activity (28.3-31.6 days post-partum). The duration of the first oestrous cycle was found to be variable, 18.0 to 20.4 days. Thirty-one per cent of the study cows did not conceive during the course of the trial and the mean calving interval of those that calved was 426 days. The high incidence of hypofunctional ovaries was a cause for concern on one farm. (author). 6 refs, 4 figs, 2 tabs

  14. Progesterone increases nitric oxide synthesis in human vascular endothelial cells through activation of membrane progesterone receptor-α.

    Progesterone exerts beneficial effects on the human cardiovascular system by inducing rapid increases in nitric oxide (NO) production in vascular endothelial cells, but the receptors mediating these nongenomic progesterone actions remain unclear. Using human umbilical vein endothelial cells (HUVECs) as a model, we show that progesterone binds to plasma membranes of HUVECs with the characteristics of membrane progesterone receptors (mPRs). The selective mPR agonist Org OD 02-0 had high binding affinity for the progesterone receptor on HUVEC membranes, whereas nuclear PR (nPR) agonists R5020 and medroxyprogesterone acetate displayed low binding affinities. Immunocytochemical and Western blot analyses confirmed that mPRs are expressed in HUVECs and are localized on their plasma membranes. NO levels increased rapidly after treatment with 20 nM progesterone, Org OD 02-0, and a progesterone-BSA conjugate but not with R5020, suggesting that this progesterone action is at the cell surface and initiated through mPRs. Progesterone and Org OD 02-0 (20 nM) also significantly increased endothelial nitric oxide synthase (eNOS) activity and eNOS phosphorylation. Knockdown of mPRα expression by treatment with small-interfering RNA (siRNA) blocked the stimulatory effects of 20 nM progesterone on NO production and eNOS phosphorylation, whereas knockdown of nPR was ineffective. Treatment with PI3K/Akt and MAP kinase inhibitors blocked the stimulatory effects of progesterone, Org OD 02-0, and progesterone-BSA on NO production and eNOS phosphorylation and also prevented progesterone- and Org OD 02-0-induced increases in Akt and ERK phosphorylation. The results suggest that progesterone stimulation of NO production in HUVECs is mediated by mPRα and involves signaling through PI3K/Akt and MAP kinase pathways.

    To evaluate artificial insemination (AI) services and reproductive efficiency in dairy herds in Uruguay two surveys were conducted in 1995 and 1996. The 1995 survey was done in 10 dairy farms of 3 regions on 696 lactating Holstein cows. The 1996 survey was done in 5 dairy farms in one region and included 768 cows. Precision of oestrus detection and efficiency of AI services were determined by milk progesterone samples taken at days 0, 10 and 23 after breeding and by analysis of the records. In 1995 and 1996, the intervals from calving to first service were 123 and 101 days, and to conception were 158 and 134 days, respectively. Parity, body weight and body condition at calving influenced these parameters, but not body weight or body condition at breeding nor milk production. Accuracy of pregnancy diagnosis by milk progesterone was 70.4%. Heat detection rate was 37.5% and pregnancy rate was 15.6%. In 1997 a second study was done to determine the factors affecting reproductive efficiency in a seasonal breeding AI programme in 328 lactating cows on 3 dairy farms. Milk progesterone measurement revealed that 12.5% of the cows were anoestrous at the beginning of the season and remained so during the trial. The category mostly affected were first-calf heifers (82%). Also, 8.5% of the cows cycling were never reported in heat and this was influenced by farm. Oestrus detection efficiency for cows determined to be cycling by progesterone profiles was evaluated in three periods of 21 days and overall efficiency was 46.9%. Main factor affecting it was farm, with an effect of parity (67.8% in mature cows and 33.2% in first-calf heifers) but no effect of days postpartum. Mean interval from the beginning of the breeding season to first service was 27.4 days, again with a strong farm variation but no effect of parity or days postpartum. In an attempt to improve reproductive efficiency in lactating dairy cows, a treatment protocol was designed, where 414 cows in two herds were

    Full Text Available Background: Progesterone is important in maintaining pregnancy. Progesterone supplementation may reduce risk of preterm birth in certain populations of pregnant women. The objective of this review was to develop evidence-based clinical recommendation for progesterone treatment in the prevention of preterm birth.Methods: A search in the Medline database was performed using keywords: progesterone, pregnancy, preterm birth, preterm labour, preterm delivery, randomized trial, and randomized controlled trial. We only included studies of vaginal progesterone treatments for the prevention of preterm birth and excluded studies on 17-α-hydroksiprogesterone caproate.Results: We report findings from twelve randomized trials conducted since 2003. These trials differ regarding inclusion criteria, progesterone dose, vehicle used, and duration of treatment. Inclusion criteria were: short uterine cervix (two trials, history of previous preterm birth (two trials, signs and symptoms of preterm labour (three trials, twin pregnancies (three trials, and multiple risk factors (among these history of previous preterm birth was the most common (two trials. Six of these twelve trials showed a significant reduction in preterm birth in the progesterone groups.Conclusions: Based on current evidence we recommend treatment with 200 mg of micronized progesterone daily, administered vaginally, in pregnant women found to have a short cervix (≤ 25 mm at 19-24 weeks. The treatment should be continued until 37 weeks.

    Onset and establishment of lactation and estrus cycles are concomitant energy – competing processes.This is because metabolic events essential to milk secretion compete for available nutrients that support processes leading to the first postpartum estrus and subsequent fertility. Net energy deficits greater than 20 Mcal / day have been reported in high yielding dairy cows. The raw material from which milk constituent is derived and the energy for their synthesis in the mammary gland is supplied by the food intake. The objective of this study was therefore to determine the effect of production system on quality, quantity of milk, postpartum estrus and conception. Friesian cows that were seven months in – calf were enrolled for this study from three production systems: Zero grazing, roadside grazed Friesian milking dairy cows were enrolled for this study using random digits. Samples of the feeds were collected at the point of feeding and taken for analysis in a nutrition laboratory. Twenty milliliters of fresh milk was collected from each cow twice a day (Evening and Morning). Milk for progesterone was also collected and progesterone determined using radioimmunoassy to determine reproductive status postpartum. The samples were analyzed to determine milk component using ecomilk machine every morning. Production and reproduction detail of each cow was recorded. The data collected was subjected to GLM of SAS and the means were separated using studentised range test. Time of parturition , production system, age , season and sex of the calf affected the shape of the lactation curve. Cow that calved during drought took too long to cycle unlike the once that calved during the wet season for all the three production systems, the calves born during rainy season were more susceptible to diseases. There was significant variation (P<0.05) in milk production and Protein content within and across production systems. The zero grazed cows had produced most milk whereas the

    The principal objective of this study was to determinate the post-partum ovarian activity in milking cows of high and low production in one farm of ecuadorian highland. For this experiment was necessary to use 48 animals between second and sith calving, the milk samples were collected according one pre-stablished protocol and the same was: one sample 5th or 6th days, twice a week until the cows were pregnacy and 180 days after parturitium if the cow is open. Additional data were compiled in each farm and both the results of the progesterone by RIA were used to determinate the diferents reproductive parameters in the post-partum of the cows. The most of reproductives parameters in the post-partum of the cows in the both group didn't have significance but the conception rate, services per conception, number of pregnacy cows and percentaje of non visibles heats had one high significance between the treatments

    Genital tract infections caused by Gram-negative bacteria induce miscarriage and are one of the most common complications of human pregnancy. LPS administration to 7-day pregnant mice induces embryo resorption after 24h, with nitric oxide playing a fundamental role in this process. We have previously shown that progesterone exerts protective effects on the embryo by modulating the inflammatory reaction triggered by LPS. Here we sought to investigate whether the in vivo administration of progesterone modulated the LPS-induced nitric oxide production from peripheral blood mononuclear cells from pregnant and non-pregnant mice. We found that progesterone downregulated LPS-induced nitric oxide production by a progesterone receptor-independent mechanism. Moreover, our results suggest a possible participation of glucocorticoid receptors in at least some of the anti-inflammatory effects of progesterone. Copyright © 2015 Elsevier B.V.

  1. Progesterone impairs social recognition in male rats.

    2012-04-01

    The influence of progesterone in the brain and on the behavior of females is fairly well understood. However, less is known about the effect of progesterone in the male system. In male rats, receptors for progesterone are present in virtually all vasopressin (AVP) immunoreactive cells in the bed nucleus of the stria terminalis (BST) and the medial amygdala (MeA). This colocalization functions to regulate AVP expression, as progesterone and/or progestin receptors (PR)s suppress AVP expression in these same extrahypothalamic regions in the brain. These data suggest that progesterone may influence AVP-dependent behavior. While AVP is implicated in numerous behavioral and physiological functions in rodents, AVP appears essential for social recognition of conspecifics. Therefore, we examined the effects of progesterone on social recognition. We report that progesterone plays an important role in modulating social recognition in the male brain, as progesterone treatment leads to a significant impairment of social recognition in male rats. Moreover, progesterone appears to act on PRs to impair social recognition, as progesterone impairment of social recognition is blocked by a PR antagonist, RU-486. Social recognition is also impaired by a specific progestin agonist, R5020. Interestingly, we show that progesterone does not interfere with either general memory or olfactory processes, suggesting that progesterone seems critically important to social recognition memory. These data provide strong evidence that physiological levels of progesterone can have an important impact on social behavior in male rats. Copyright © 2012 Elsevier Inc. All rights reserved.

    A direct (non-extraction) radioimmunoassay method for progesterone determination in blood plasma has been presented. A new progesterone derivative substituted at 12α position was used as antigen for production of antibody. Cheap and easily accessible substrate -deoxycholic acid - was used as starting material for 9 step degradation procedure yielding 12α-hydroxy-progesterone. The latter compound was subsequently esterified with succinic anhydrine and conjugated with bovine serum albumin. The conjugate was then used for the immunization of rabbits to obtain immune antisera. After the detailed characterization, the obtained antibodies have been used for the determination of progesterone in human and cattle blood plasma. Transcortin present in samples used for the determinations was saturated with the excess of cortisol. The sensitivity of the method was found to be 5 pg in a sample, which corresponds to the concentration of about 0.25 ng/ml in blood plasma, in as much as the volume of plasma used for analysis was 20 ml. The within-series error was 7% when progesterone concentration in plasma samples was higher than 2.5 ng/ml. (author)

    Objectives were to determine associations between percentage pregnancy loss (PPL) in dairy cattle and: (i) pregnancy diagnosis by ultrasonography; (ii) pregnancy diagnosis by serum pregnancy-specific protein B (PSPB) concentrations, with or without serum progesterone concentrations; and (iii) production and environmental factors. This study included 149 822 pregnancy diagnoses conducted over 13 years in Holstein-Friesian cows in Hungarian dairy herds. The following were determined: PPL in cows diagnosed pregnant by transrectal ultrasonography 29-42 days after artificial insemination (AI; n = 11 457); PPL in cows diagnosed pregnant by serum PSPB 29-35 days after AI (n = 138 365); and PPL and its association with serum progesterone concentrations, PSPB and production/environmental variables. The definition of PPL was percentage of cows initially diagnosed pregnant based on ultrasonography or PSPB, but not pregnant when examined by transrectal palpation 60 -70 days after AI. The PPL was lower (p 1.1 ng/ml) was lowest (15.0%), whereas cows with low concentrations of both PSPB and progesterone (0.6-1.1 and production, when ambient temperatures were high, although body condition score (BCS) had no effect on PPL. Finally, there were no significant associations between serum PSPB and environmental temperatures or number of post-partum uterine treatments. © 2016 Blackwell Verlag GmbH.

  5. Progesterone as a bone-trophic hormone.

    Science.gov (United States)

    Prior, J C

    1990-05-01

    Experimental, epidemiological, and clinical data indicate that progesterone is active in bone metabolism. Progesterone appears to act directly on bone by engaging an osteoblast receptor or indirectly through competition for a glucocorticoid osteoblast receptor. Progesterone seems to promote bone formation and/or increase bone turnover. It is possible, through estrogen-stimulated increased progesterone binding to the osteoblast receptor, that progesterone plays a role in the coupling of bone resorption with bone formation. A model of the interdependent actions of progesterone and estrogen on appropriately-"ready" cells in each bone multicellular unit can be tied into the integrated secretions of these hormones within the ovulatory cycle. Figure 5 is an illustration of this concept. It shows the phases of the bone remodeling cycle in parallel with temporal changes in gonadal steroids across a stylized ovulatory cycle. Increasing estrogen production before ovulation may reverse the resorption occurring in a "sensitive" bone multicellular unit while gonadal steroid levels are low at the time of menstrual flow. The bone remodeling unit would then be ready to begin a phase of formation as progesterone levels peaked in the midluteal phase. From this perspective, the normal ovulatory cycle looks like a natural bone-activating, coherence cycle. Critical analysis of the reviewed data indicate that progesterone meets the necessary criteria to play a causal role in mineral metabolism. This review provides the preliminary basis for further molecular, genetic, experimental, and clinical investigation of the role(s) of progesterone in bone remodeling. Much further data are needed about the interrelationships between gonadal steroids and the "life cycle" of bone. Feldman et al., however, may have been prophetic when he commented; "If this anti-glucocorticoid effect of progesterone also holds true in bone, then postmenopausal osteoporosis may be, in part, a progesterone deficiency

    1980-01-01

    A rapid, precise radioimmunoassay for progesterone in 25 μL of unextracted serum is described. Progesterone is released from its binding protein by adding an optimal amount of cortisol, which binds to the same protein (cortisol binding globulin) as progesterone. The amount of cortisol required does not cross react with the specific progesterone antibody used. This approach considerably shortens assay time and removes a tedious and imprecise stage in the conventional assay of serum progesterone. Results correlated well (r = 0.97) with a method involving organic solvent extraction of progesterone from serum. During the two years we have used this mehod in a busy diagnostic endocrine laboratory, the between-assay precision (CV) for low-, medium-, and high-concentration quality control sera was 12, 7, and 9%, respectively. Data from participation in an independent external quality-control program verified the adequacies of the method

    Uterine bacterial infection perturbs uterine and ovarian functions in postpartum dairy cows. Peptidoglycan (PGN) produced by gram-positive bacteria has been shown to disrupt the ovarian function in ewes. The aim of this study was to determine the effect of PGN on steroid production in bovine theca cells at different stages of follicular development. Bovine theca cells isolated from pre- and post-selection ovarian follicles (8.5mm in diameter, respectively) were cultured in vitro and challenged with PGN. Steroid production was evaluated by measuring progesterone (P4) and androstenedione (A4) concentration in culture media after 48 h or 96 h of culture. Bovine theca cells expressed PGN receptors including Toll-like receptor 2 and nucleotide-binding oligomerization domain 1 and 2. Treatment with PGN (1, 10, or 50 μg/ml) led to a decrease in P4 and A4 production by theca cells in both pre- and post-selection follicles. The mRNA expression of steroidogenic enzymes were decreased by PGN treatment. Moreover, A4 production was further suppressed when theca cells of post-selection follicles were simultaneously treated by PGN and lipopolysaccharide (0.1, 1, or 10 μg/ml). These findings indicate that bacterial toxins may act locally on ovarian steroidogenic cells and compromise follicular development in postpartum dairy cows. Copyright © 2014 Elsevier Ltd.

    Planned reproduction in cattle involves regulation of estrous cycle and the use of artificial insemination. Cycle control includes the administration of exogenous progesterone during 5-8 days in a controlled manner allowing females to synchronize their ovulation. Several progesterone delivery systems are commercially available but they have several drawbacks. The aim of the present contribution was to evaluate chitosan microparticles entrapping progesterone as an alternative system. Microparticles were prepared by spray drying. The effect of formulation parameters and experimental conditions on particle features and delivery was studied. A mathematical model to predict progesterone plasma concentration in animals was developed and validated with experimental data. Microparticle size was not affected by formulation parameters but sphericity enhances as Tween 80 content increases and it impairs as TPP content rises. Z potential decreases as phosphate content rises. Particles remain stable in acidic solution but the addition of surfactant is required to stabilize dispersions in neutral medium. Encapsulation efficiencies was 69-75%. In vitro delivery studies showed burst and diffusion-controlled phases, being progesterone released faster at low pH. In addition, delivery extend in cows was affected mainly by particle size and hormone initial content, while the amount injected altered plasma concentration. Theoretical predictions with excellent accuracy were obtained. The mathematical model developed can help to find proper particle features to reach specific delivery rates in the animals. This not only save time, money and effort but also minimized experimentation with animals which is desired from an ethical point of view.

    Progesterone is one of the steroids secreted by the corpus Iuteum in females during the menstrual cycle, and in a much higher amount by the placenta during pregnancy. It is also secreted in a minor quantities by the adrenal cortex in both males and females. Measurement of serum progesterone represents one of diagnostic values in menstrual disorders and infertility. The progesterone radioimmunoassay is based on the competition between unlabelled progesterone and a fixed quantity of 125 I-labeled progesterone for a limited number of binding sites on progesterone specific antibody. Allowing for a fixed amount of magnetizable immunosorbent to react, the antigen-antibody complex is bound on solid particles which are then separated by magnetic rack, and the radioactivity of the solid phase was counted using gamma counter. In this work, the chemical kinetics of the assay was followed, where the specific rate constant (K) was calculated at 4 degree and 37 degree and the activation energy (E act ) were calculated and the reaction rate was deduced

    Preparation and purification of radioiodinated progesterone derivatives for the development of a radioimmunoassay of progesterone is described. Two procedures have been standardized for preparing radioiodinated progesterone conjugate. In the first procedure 125 I labeled histamine was conjugated to progesterone 11 α hemisuccinate by the mixed anhydride method. In the second procedure, tyrosyl methyl ester was conjugated to progesterone 11 α hemisuccinate and iodination of the conjugate was carried out. Purification of the iodinated products was carried out by solvent extraction and thin layer chromatography techniques. The radiochemical purity of the tracers prepared by both methods were more than 95%. Labeled progesterone derivatives prepared were used for developing a radioimmunoassay procedure. The non-specific binding of the tracer was about 2-3%, while up to 80% binding could be obtained in the presence of excess antibody. The radioiodinated tracer could be used up to four months in the assay. (author) 12 refs.; 2 figs.; 2 tabs

  14. The benefits of progesterone therapy in imminent abortion

    Directory of Open Access Journals (Sweden)

    2005-12-01

    Full Text Available The causes of imminent abortion are multi-factorial. The biggest causal factor is the low level of serum progesterone level. The lowest critical level of serum progesterone for survivability of pregnancy is 10 ng/ml. Eighty percent of patients experiencing abortion showed that their progesterone level was < 10 ng/ml. Patients who realized that their pregnancy would experience hemorrhage generally would suffer from depression. Stress was one of the factors responsible for the occurence of abortion. Administration of natural progesterone substitution (not  progestogen accelerates the disappearance of uterine contractions, and speeds up the stoppage of bleeding. In addition, progesterone has the effect of anti-anxiety. Adminstration of oral progesterone would result in metabolism in the intestine and liver, such that physiological level of serum progesterone could not be reached, while administration of suppositoria progesterone would result in physiological level of serum, such that it was effective to prevent imminent abortion.

    Progesterone production is essential for growth and development of the conceptus during pregnancy. Abnormal development of the corpus luteum (CL) after conception can result in early embryonic loss or fetal abortion. Routine monitoring of bottlenose dolphin (Tursiops truncatus) pregnancy after artificial insemination or natural conception with ultrasonography and serum progesterone determination has allowed for the establishment of expected fetal growth rates and hormone concentrations. Using these monitoring techniques, we revealed four pregnant dolphins (12-24 yr old) with abnormally low progesterone production indicative of luteal insufficiency. Once diagnosed, animals were placed on altrenogest (0.044-0.088 mg/kg once daily) alone or with oral progesterone (50-200 mg twice daily). Doses of hormone were increased or decreased in each animal based on how fetal skull biparietal and thoracic growth rates compared with published normal values. Hormones were withdrawn starting from day 358 of gestation in animals 1 and 2, with labor occurring 6 and 7 days after withdrawal and at 376 and 373 days of gestation, respectively. Both deliveries were dystocic, with each calf requiring manual extraction and fetotomy for calf 1. The fetuses in animals 3 and 4 died at 348 and 390 days of gestation, respectively. Induction of labor was attempted in both animals, after fetal death, by using a combination of rapid progesterone withdrawal and steroid and prostaglandin F2alpha administration. The calf of animal 4 had to be removed with manual cervical dilation and fetotomy All adult females survived the procedures. These data provide the first in vivo evidence that the CL is the primary source of progesterone throughout pregnancy in the bottlenose dolphin. Until further characterization of hormones required during pregnancy and at parturition has been accomplished, the exogenous progestagen supplementation protocol described here cannot be recommended for treatment of progesterone

    Negative affect (NA) and positive affect (PA) in the early postpartum period have been associated with postpartum depressive symptoms, but the exact relationship is not well understood. This study aimed to determine if NA and PA in the immediate postpartum period predicted postpartum depressive symptoms over and above well-established predictors (previous trauma, history of depression). Participants were prospectively recruited from a Mother-Baby Unit at a large Midwestern academic medical center in the United States from April 2011 to April 2014. Participants (N=526) completed the Daily Experiences Questionnaire (DEQ), a self-report measure which assessed NA and PA, within three days post-delivery. Participants then reported their depressive symptoms at two weeks (n=364) and twelve weeks postpartum (n=271). Hierarchical regression analyses indicated that low PA and high NA after birth significantly predicted depressive symptoms early (at 2 weeks) and later (at 12 weeks) in the postpartum period, over and above previous traumatic experiences and history of depression. The sample was relatively homogenous, and data were from self-report instruments. The current study found NA and PA in the days immediately after birth predicted depressive symptoms at multiple time points in the postpartum period. Because the perinatal period places women at a higher risk for depressive symptomatology, prevention and early intervention are critical. Measuring affect in hospitals immediately after birth may provide a more normalized set of items that is predictive of later depression, which will allow physicians to identify those at highest risk for developing depressive symptoms.

    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.

    Objectives The aims of this study were to evaluate the predictive relationship between psychological symptomatology 24 h postpartum and depression 4 months postpartum, and analyze the relationship between estradiol and postpartum mood. Methods Two hundred women participated in an assessment 24 h postpartum and gave a blood sample for estradiol analysis. One hundred eleven of these women completed the second assessment 4 months postpartum. The Beck Depression Inventory II and the Scale of State-Trait Anxiety were used to assess psychological symptoms. Results At 24 h postpartum, symptoms of depression, trait anxiety, and state anxiety were all significantly correlated with each other. Depression at 24 h postpartum was the only significant independent predictor of depression at 4 months postpartum, explaining 28.7% of the variance. No statistically significant relationship was found between levels of estradiol and mood. Symptoms of depression immediately postpartum thus appear to be a predictor of postpartum depression. Conclusions for Practice These results suggest that early postpartum psychological evaluation of the mother, and intervention as warranted, might prevent or lessen postpartum depression.

    The incidence of different types of luteal activity postpartum and their effect on reproductive performance were studied in 21 postpartum dairy cows. Progesterone concentrations in defatted milk collected 3 times a week were determined by EIA. Reproductive tract examination was undertaken every other week postpartum. Body weight and body condition score (BCS) were measured before and after calving and the average 100-day milk yield was calculated. Nine (42.9%) cows had normal ovarian activity (first luteal activity or = 20 days pre-service) and in 7 (33.3%) cows the first luteal activity was shown later than 50 days postpartum (DOV). When compared with normal cows, both PLP and DOV had longer interval to first insemination (63.1 +/- 22.0 days versus 77.6 +/- 21.6 and 93.0 +/- 22.3 days, Pconception rate (88.9% versus 0.0% and 57.1%, P<0.01 and P<0.05, respectively) and greater BCS loss (0.81 +/- 0.2 versus 1.05 +/- 0.21 and 1.04 +/- 0.10, respectively, P<0.01). Cows with PLP showed longer interval to uterine involution than normal and DOV groups (54.0 +/- 8.3 days versus 42.4 +/- 5.5 and 43.3 +/- 8.3 days, respectively, P<0.01) and higher 100-day milk yield (38.8 +/- 2.7 kg versus 33.6 +/- 4.7 and 29.9 +/- 6.1 kg, respectively, P<0.01). In conclusion, more than half of the cows had abnormal luteal activity postpartum, which adversely affected reproductive performance.

    Endometriosis is a common cause of pelvic pain and affects up to 10% of women of reproductive age. Aberrant progesterone signaling in the endometrium plays a significant role in impaired decidualization and establishment of ectopic endometrial implants. Eutopic endometrial cells from women with endometriosis fail to downregulate genes needed for decidualization, such as those involved in cell cycle regulation, leading to unbridled proliferation. Several causes of progesterone resistance in the endometrium have been postulated, including congenital "preconditioning", whereby the in utero environment renders infants susceptible to neonatal uterine bleeding and endometriosis. Progesterone action is crucial to decreasing inflammation in the endometrium, and deviant progesterone signaling results in a proinflammatory phenotype. Conversely, chronic inflammation can induce a progesterone-resistant state. Repetitive retrograde endometrial shedding begets chronic peritoneal inflammation, which further exacerbates progesterone resistance. Genetic causes of progesterone resistance include progesterone receptor gene polymorphisms, altered microRNA expression, and epigenetic modifications to progesterone receptors and their targets. Environmental toxins such as dioxin play a possible role in the genesis of endometriosis by permitting an inflammatory milieu. A consequence of impaired progesterone action is that hormonal therapy is rendered ineffective for a subset of women with endometriosis. Synthetic progestins, such as dienogest, may overcome this phenomenon by increasing progesterone receptor expression and decreasing proinflammatory cytokines. Other modalities include high dose depot formulations of progestins, medicated intrauterine devices and the likely advent of oral GnRH antagonists. Unearthing root causes of progesterone inaction in endometriosis will aid in the development of novel therapeutics geared toward prevention and treatment. © 2017 Nordic Federation of

    The aim of this article is to review the physiology of progesterone and focus on its physiological actions on tissues such as endometrium, uterus, mammary gland, cardiovascular system, central nervous system and bones. In the last decades, the interest of researchers has focused on the role of progesterone in genomic and non-genomic receptor mechanisms. We searched PubMed up to December 2014 for publications on progesterone/steroidogenesis. A better understanding of the biological genomic and non-genomic receptor mechanisms could enable us in the near future to obtain a more comprehensive knowledge of the safety and efficacy of this agent during hormone replacement therapy (natural progesterone), in vitro fertilization (water-soluble subcutaneous progesterone), in traumatic brain injury, Alzheimer's disease and diabetic neuropathy, even though further clinical studies are needed to prove its usefulness. © 2015 Nordic Federation of Societies of Obstetrics and Gynecology.

    Full Text Available The impact of a premature elevation of serum progesterone level, the day of hCG administration in patients under controlled ovarian stimulation during IVF procedure, on human endometrial receptivity is still debated. In the present study, we investigated the endometrial gene expression profile shifts during the prereceptive and receptive secretory stage in patients with normal and elevated serum progesterone level on the day of hCG administration in fifteen patients under stimulated cycles. Then, specific biomarkers of endometrial receptivity in these two groups of patients were tested. Endometrial biopsies were performed on oocyte retrieval day and on day 3 of embryo transfer, respectively, for each patient. Samples were analysed using DNA microarrays and qRT-PCR. The endometrial gene expression shift from the prereceptive to the receptive stage was altered in patients with high serum progesterone level (>1.5 ng/mL on hCG day, suggesting accelerated endometrial maturation during the periovulation period. This was confirmed by the functional annotation of the differentially expressed genes as it showed downregulation of cell cycle-related genes. Conversely, the profile of endometrial receptivity was comparable in both groups. Premature progesterone rise alters the endometrial gene expression shift between the prereceptive and the receptive stage but does not affect endometrial receptivity.

    Postpartum depression is a prevalent disorder affecting many women of reproductive age. Despite increasing public awareness, it is frequently underdiagnosed and undertreated leading to significant maternal morbidity and adverse child outcomes. When identified, postpartum depression is usually treated as major depressive disorder. Many studies have identified the postpartum as a period of high risk for first presentations and relapses of bipolar disorder. Areas covered: This article reviews the acute and prophylactic treatment of postpartum major depressive disorder, bipolar depression and major depressive disorder with mixed features. The safety of antidepressant and mood stabilizing medications in pregnancy and breastfeeding will also be reviewed. Expert commentary: Differentiating postpartum major depressive disorder and postpartum bipolar depression can be difficult given their clinical similarities but accurate identification is vital for initiating proper treatment. Antidepressants are the mainstay of drug treatment for postpartum major depressive disorder, yet randomized controlled trials have shown conflicting results. A paucity of evidence exists for the effectiveness of antidepressant prophylaxis in the prevention of recurrences of major depressive disorder. Mood stabilizing medications reduce the risk of postpartum bipolar depression relapse but no randomized controlled trials have examined their use in the acute or prophylactic treatment of postpartum bipolar depression.

    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.

    Application of assisted reproductive technologies in buffaloes is limited to some extent by farmers' inability to detect oestrus because of its poor expression. The present study aimed at investigating reliability of a milk progesterone enzyme-linked immunosorbent assay (ELISA) to assess the ovarian cyclicity during post partum, oestrus and post-breeding periods in water buffaloes. Progesterone concentrations were measured by an ELISA in milk of 23 postpartum buffaloes in relation to oestrus, pregnancy, body condition score (BCS) and milk production. Two milk samples were taken at 10 days intervals, every month starting from day 30 and continued to day 150 post partum. BCS and milk production were recorded during sample collection. Milk samples from bred buffaloes were collected at Day 0 (day of breeding), Days 10-12 and Days 22-24. Defatted milk was preserved at -80°C until analysis. Pregnancy was confirmed by palpation per rectum on Days 70-90. Seventeen buffaloes had 47 ovulatory cycles, one to four in each, 13 were detected in oestrus once (28 % oestrus detection rate). Progesterone concentration ≥1 ng/ml in one of the two 10-day-interval milk samples reflected ovulation and corpus luteum formation. The intervals between calving to first luteal activity and to first detected oestrus varied from 41 to 123 days (n = 17) and 83 to 135 (n = 13) days, respectively. Eight buffaloes were bred in the course of the study and seven were found pregnant. These buffaloes had a progesterone profile of low (progesterone ELISA is a reliable tool for monitoring ovarian cyclicity and good BCS may be an indicator of resuming cyclicity in water buffalo.

    Placental tissue slices of guinea-pigs were incubated in Krebs-Ringer phosphate buffer containing NAD and glucose using pregnenolone-4- 14 C as a substrate. The amount of progesterone converted from pregnenolone by the placenta at 50 days after mating was significantly larger than that of 64-65 days after mating (0.205 and 0.159 μg/100 mg/hr., P < 0.05). The 3 β-hydroxysteroid dehydrogenase activity of the placenta seems to decrease at the last stage of pregnancy. Progesterone levels in the systemic and uterine venous plasma of the pregnant guinea-pigs were measured. There was no significant difference between them at the middle and later stages of pregnancy. This suggested that uterine venous plasma progesterone level was not affected by the placental progesterone. The progesterone levels in both systemic and uterine venous plasma were high in middle stage and low at the end of pregnancy, but rapid decrease of progesterone reflecting initiation of parturition, as seen in many other species, was not observed. In this species, the relationship between progesterone level and initiation of parturition is seemed to be specific, being complicated by the local effect of placental progesterone on the fetus or the uterus.

    1980-01-01

    A patient with previously diagnosed Graves' hyperthyroidism had a transient episode of thyrotoxicosis three months postpartum. This was associated with a diffusely enlarged thyroid gland, a rise in antithyroid microsomal antibody titer, a 24-hour radioactive iodine uptake (RAIU) of 1%, and an aspiration biopsy specimen suggestive of chronic lymphocytic thyroiditis. An alternative cause for the depressed RAIU was not discovered. This case would suggest that patients with previously diagnosed Graves' disease can have thyrotoxicosis without an enhanced RAIU and that the postpartum thyrotoxin syndrome may involve an immunologic injury causing a release of performed thyroid hormone

    Test performance of two automated progesterone assays available on the immunoassay analysers Abbott AxSYM and Technicon Immuno 1, respectively, was evaluated in comparison with the radioimmunoassay Progesterone MAIA. For assessment of test performance imprecision, functional sensitivity and linearity of dilution was examined. Correlation with the manual radioimmunoassay was assessed using 122 serum samples over the range 0-110 nmol/L. Imprecision studies revealed for the AxSYM Progesterone within-run CV's of 1.8-6.4% and day-to-day CV's of 3.5-9.7% (concentration range 2.3-75 nmol/L); Immuno 1 Progesterone: within-run CV's 1.0-7.3%, day-to-day CV's 2.3-7.7% (concentration range 1.2-60 nmol/L). The functional sensitivity was <1.7 nmol/L for the AxSYM Progesterone and <1.1 nmol/L for the Immuno 1 Progesterone. With the AxSYM Progesterone the mean recovery after dilution from five samples was 102% (89-107%), from one sample only 69-80% was recovered; with the Immuno 1 Progesterone the mean recovery was 95% (80-105%). Despite of a quite good overall correlation (coefficients 0.972 and 0.981) the relationship of both assays to the Progesterone MAIA significantly deviate from linearity with a considerably higher slope within the lower concentration range. The relationship between the automated assays was linear over the entire concentration range (Immuno = 1.207 * AxSYM + 1; r = 0.986). The time to first result was 20 min for the AxSYM Progesterone, 45 min for the Immuno 1 Progesterone and 90 min for the Progesterone MAIA. The evaluated progesterone assays both exhibit an excellent precision and a high degree of sensitivity. They offer a rapid and flexible method for progesterone determination which may be especially useful for the monitoring of ovarian stimulation during in-vitro fertilization. (author)

    The aim of this research was to study the roles of the day 0 energy balance and gonadotrophin-releasing hormone (GnRH) and progesterone levels on dominant follicle (DF) and corpus luteum (CL) development during the first 7 days of a gonadotrophin-prostaglandin-gonadotrophin (GPG) + progesterone (P4) program in anoestrous dairy cows. Cows (n = 81) were allocated to one of the three treatments: (1) GPG + P4 (days 0 and 9, 100 µg GnRH; day 0-7, intravaginal P4 device; day 7, 500 µg PGF 2α ); (2) GPG (as for treatment 1 but excluding the P4 device) and (3) prostaglandin + GnRH + P4 (as for treatment 1, but excluding day 0 GnRH). DF and CL size, plasma concentrations of insulin, insulin-like growth factor-I (IGF-I) and non-esterified fatty acid (NEFA) were measured on days 0 and 7. The proportion of cows with a CL on day 7 was significantly different between groups (GPG: 78%, GPG+P4: 69%, PGF 2α + GnRH + P4: 42%, P = 0.02). The CL volume on day 7 was significantly associated with treatment, treatment by time postpartum and plasma concentrations of insulin, IGF-I and NEFA. In cows without a CL present on day 0 of an oestrus synchronisation program, removal of the day 0 GnRH treatment led to reduced CL development; however, no effect of adding progesterone was found. In contrast, in cows with a CL present on day 0 inclusion of a progesterone device led to a higher CL volume, but removal of the first GnRH injection had no effect. Response to the treatment was affected by plasma concentrations of insulin, IGF-I and NEFA. © 2017 Australian Veterinary Association.

    The corpus luteum (CL) is under control of gonadotrophic hormones and produces progesterone, which is necessary for endometrial receptivity. Recent studies have shown that progesterone and its metabolites are involved in cell proliferation and apoptosis of cancer cells. Here weanalyzed the role of progesterone and its meta-bolites on luteinized granulosa cells (LGC) by FACS analysis and quantitative Real-Time PCR. We detected the mRNA of the progesterone metabolizing genes SRD5A1, AKR1C1, and AKR1C2 in LGC. The stimulation of LGC with progesterone or progesterone metabolites did not show any effect on the mRNA expression of these genes. However, a downregulation of Fas expression was found to be accomplished by progesterone and human chorionic gonadotropin. Our findings do not support the concept of an effect of progesterone metabolites on LGCs. However, it suggests an antiapoptotic effect of hCG and progesterone during corpus luteum development by downregulation of Fas. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available Abstract Background Application of assisted reproductive technologies in buffaloes is limited to some extent by farmers’ inability to detect oestrus because of its poor expression. The present study aimed at investigating reliability of a milk progesterone enzyme-linked immunosorbent assay (ELISA to assess the ovarian cyclicity during post partum, oestrus and post-breeding periods in water buffaloes. Methods Progesterone concentrations were measured by an ELISA in milk of 23 postpartum buffaloes in relation to oestrus, pregnancy, body condition score (BCS and milk production. Two milk samples were taken at 10 days intervals, every month starting from day 30 and continued to day 150 post partum. BCS and milk production were recorded during sample collection. Milk samples from bred buffaloes were collected at Day 0 (day of breeding, Days 10–12 and Days 22–24. Defatted milk was preserved at −80°C until analysis. Pregnancy was confirmed by palpation per rectum on Days 70–90. Results Seventeen buffaloes had 47 ovulatory cycles, one to four in each, 13 were detected in oestrus once (28 % oestrus detection rate. Progesterone concentration ≥1 ng/ml in one of the two 10-day-interval milk samples reflected ovulation and corpus luteum formation. The intervals between calving to first luteal activity and to first detected oestrus varied from 41 to 123 days (n = 17 and 83 to 135 (n = 13 days, respectively. Eight buffaloes were bred in the course of the study and seven were found pregnant. These buffaloes had a progesterone profile of low (P P  Conclusions Milk progesterone ELISA is a reliable tool for monitoring ovarian cyclicity and good BCS may be an indicator of resuming cyclicity in water buffalo.

    Women are at very high risk for the first onset of acute and severe mood disorders the first weeks after delivery. Tryptophan breakdown is increased as a physiological phenomenon of the postpartum period and might lead to vulnerability for affective psychosis (PP) and severe depression (PD). The aim of the current study was to investigate alterations in tryptophan breakdown in the physiological postpartum period compared to patients with severe postpartum mood disorders. We included 52 patients (29 with PP, 23 with PD), 52 matched healthy postpartum women and 29 healthy non-postpartum women. Analyzes of serum tryptophan metabolites were performed using LC-MS/MS system for tryptophan, kynurenine, 3-hydroxykynurenine, kynurenic acid and 5-hydroxyindoleacetic acid. The first two months of the physiological postpartum period were characterized by low tryptophan levels, increased breakdown towards kynurenine and a downstream shift toward the 3-OH-kynurenine arm, away from the kynurenic acid arm. Kynurenine was significantly lower in patients with PP and PD as compared to healthy postpartum women (p=0.011 and p=0.001); the remaining tryptophan metabolites demonstrated few differences between patients and healthy postpartum women. Low prevalence of the investigated disorders and strict exclusion criteria to obtain homogenous groups, resulted in relatively small sample sizes. The high kynurenine levels and increased tryptophan breakdown as a phenomenon of the physiological postpartum period was not present in patients with severe postpartum mood disorders. No differences were observed in the levels of the 'neurotoxic' 3-OH-kynurenine and the 'neuroprotective' kynurenic acid arms between patients and healthy postpartum women.

  8. Progesterone is essential for protecting against LPS-induced pregnancy loss. LIF as a potential mediator of the anti-inflammatory effect of progesterone.

    Directory of Open Access Journals (Sweden)

    Julieta Aisemberg

    Full Text Available Lipopolysaccharide (LPS administration to mice on day 7 of gestation led to 100% embryonic resorption after 24 h. In this model, nitric oxide is fundamental for the resorption process. Progesterone may be responsible, at least in part, for a Th2 switch in the feto-maternal interface, inducing active immune tolerance against fetal antigens. Th2 cells promote the development of T cells, producing leukemia inhibitory factor (LIF, which seems to be important due to its immunomodulatory action during early pregnancy. Our aim was to evaluate the involvement of progesterone in the mechanism of LPS-induced embryonic resorption, and whether LIF can mediate hormonal action. Using in vivo and in vitro models, we provide evidence that circulating progesterone is an important component of the process by which infection causes embryonic resorption in mice. Also, LIF seems to be a mediator of the progesterone effect under inflammatory conditions. We found that serum progesterone fell to very low levels after 24 h of LPS exposure. Moreover, progesterone supplementation prevented embryonic resorption and LPS-induced increase of uterine nitric oxide levels in vivo. Results show that LPS diminished the expression of the nuclear progesterone receptor in the uterus after 6 and 12 h of treatment. We investigated the expression of LIF in uterine tissue from pregnant mice and found that progesterone up-regulates LIF mRNA expression in vitro. We observed that LIF was able to modulate the levels of nitric oxide induced by LPS in vitro, suggesting that it could be a potential mediator of the inflammatory action of progesterone. Our observations support the view that progesterone plays a critical role in a successful pregnancy as an anti-inflammatory agent, and that it could have possible therapeutic applications in the prevention of early reproductive failure associated with inflammatory disorders.

    The post-partum reproductive performance of adult West African ewes of proven fertility was studied to assess the beneficial effect of both 14 and 18 h restricted nursing or early weaning (35 days post-lambing) on the resumption of ovarian function and conception rate at first oestrus. Although the interval from lambing to first oestrus and/or conception in the 14 h nursing (55.13±11.03 days), 18 h nursing (65.00±15.65 days) and control (59.00±13.48 days) groups did not differ, the percentage of ewes that showed oestrus (90, 60 and 50% respectively) favoured the treatment with the shortest nursing time. When lambs were weaned early, the interval from lambing to oestrus (61.40±16.50 days) did not differ significantly from that for the 14 h nursing ewes (70.10±19.37 days) but tended to be lower than for the controls (94.25±62.38 days). Since differences in response were assumed to be dependent on body condition of the individual ewes at the time of lambing, and body weight changes of the dams after lambing were correlated with progesterone hormone, plasma proteins, glucose and free fatty acids, it was assumed that the beneficial effects of the treatments on the reproductive parameters were due to the partition of nutrients towards restoration of body reserves and subsequently to the secretion of progesterone.

    The term progesterone should only be used for the natural hormone produced by the ovaries or included in a registered drug. The modern history of progesterone begins with the first book-length description of the female reproductive system including the corpus luteum and later with the Nobel Prize winner, Adolf Butenandt who took a crucial step when he succeeded in converting pregnanediol into a chemically pure form of progesterone, the corpus luteum hormone. The deficient production of progesterone was shown first to be the cause of the luteal-phase deficiency responsible for infertility and early pregnancy loss due to inadequate secretory transformation of the endometrium. Later, progesterone was confirmed to be the best and safest method of providing luteal-phase support in assisted reproductive technology. Progesterone provides adequate endometrial protection and is suggested to be the optimal progestagen in menopausal hormone therapy in terms of cardiovascular effects, venous thromboembolism, probably stroke and even breast cancer risk. Neuroprotective effects of progesterone have also been demonstrated in several of experimental models including cerebral ischemic stroke and Alzheimer's disease. Vaginal progesterone was shown to decrease the risk of preterm birth in women with a mid-trimester sonographic short cervix and to improve perinatal outcomes in singleton and twin gestations.

    A strong tradition exists in the psychiatric literature to consider postpartum depression a distinct diagnosis. However, the empirical evidence indicates that, in terms of etiology and relapse rates, postpartum depression is indistinguishable from non-postpartum depression. Symptomatically, postpartum depression seems to involve a milder disturbance, suggesting that it is best seen as an adjustment disorder. This paper summarizes the empirical evidence relevant to the distinct diagnosis quest...

    To quantify the contribution of placenta accreta to the rate of postpartum hemorrhage and severe postpartum hemorrhage. All hospital deliveries in Canada (excluding Quebec) for the years 2009 and 2010 (N=570,637) were included in a retrospective cohort study using data from the Canadian Institute for Health Information. Placenta accreta included placental adhesion to the uterine wall, musculature, and surrounding organs (accreta, increta, or percreta). Severe postpartum hemorrhage included postpartum hemorrhage with blood transfusion, hysterectomy, or other procedures to control bleeding (including uterine suturing and ligation or embolization of pelvic arteries). Rates, rate ratios, population-attributable fractions (ie, incidence of postpartum hemorrhage attributable to placenta accreta), and 95% confidence intervals (CIs) were estimated. Logistic regression was used to quantify associations between placenta accreta and risk factors. The incidence of placenta accreta was 14.4 (95% CI 13.4-15.4) per 10,000 deliveries (819 cases among 570,637 deliveries), whereas the incidence of placenta accreta with postpartum hemorrhage was 7.2 (95% CI 6.5-8.0) per 10,000 deliveries. Postpartum hemorrhage among women with placenta accreta was predominantly third-stage hemorrhage (41% of all cases). Although placenta accreta was strongly associated with postpartum hemorrhage (rate ratio 8.3, 95% CI 7.7-8.9), its low frequency resulted in a small population-attributable fraction (1.0%, 95% CI 0.93-1.16). However, the strong association between placenta accreta and postpartum hemorrhage with hysterectomy (rate ratio 286, 95% CI 226-361) resulted in a population-attributable fraction of 29.0% (95% CI 24.3-34.3). Placenta accreta is too infrequent to account for the recent temporal increase in postpartum hemorrhage but contributes substantially to the proportion of postpartum hemorrhage with hysterectomy.

    The progesterone concentration in milk-fat was determined in samples from 167 cows in 51 herds taken on day 0, 6 and 20 after artificial insemination. The rectal palpation verified pregnancy in 85% of the cows classified on their milk-progesterone concentration as ''probably pregnant''. According to the milk progesterone concentration it was possible already three weeks after artificial insemination to classify 25% of all examined cows as ''non pregnant''. Seven cows were inseminated at an inappropriate time as revealed by a high progesterone concentration in milk-fat on the day of insemination. The relevance of milk progesterone determinations as an aid for veterinary surgeons is briefly discussed. (author)

    The determination of progesterone concentration in whole and fat-free milk 19-24 days after conception enables to distinguish fertile and non-fertile insemination, which is important in cattle breeding. The aim of this work was to develop a simple and quick radioimmunoassay test for the determination of progesterone in cow milk. Two types of solid-phase tubes coated with specific polyclonal anti-progesterone antibody from ORION Diagnostica and BIOSOURCE International, two different progesterone derivatives viz. progesterone-3- carboxymethyl oxime (CMO) and progesterone-11α-hemisuccinate (HS) conjugated to 125 I-histamine and the HPLC system with Lichrospher RP-18 column along with 65% acetonitrile/water as eluent to purify the tracers were used to carry out this work. Progesterone-3CMO- 125 I-histamine had a retention time of 13.2 min and progesterone-11α-hemisuccinate- 125 I-histamine had a retention time of 7.8 min. Two kinds of kits (kit I and kit II) were prepared, first with progesterone-3CMO- 125 I-histamine as the tracer and coated tubes from Progesterone Veterinary RIA kit of ORION Diagnostica and the second with progesterone-11αHS- 125 I-histamine as the tracer and coated tubes from Progesterone Veterinary RIA kit from BIOSOURCE International. Progesterone from Sigma and selected fat-free cow's milk without progesterone as zero progesterone milk matrix were used for standard preparation. The optimal assay procedure was as follows: 50μL standards, controls and fat-free milk samples were pipetted into coated tubes followed by addition of 500μL of diluted tracer. The tubes were incubated for 2h in case of kit I and 3h for kit II at RT. After the incubation, the tubes were decanted and counted. The assay range was 0 to 270 nmol/L for kit I and 0 to 300 nmol/L for kit II. The sensitivity of the kit with ORION coated tubes was better (0.8 nmol/L) than that of BIOSOURCE tubes which was 1.5 nmol/L. Validation of these assays in terms of specificity, accuracy

One woman dies every seven minutes, at the same time, one-quarter of all maternal death worldwide is being caused by PPH. The aim of United Nations Fifth Millennium Development Goal 5 is to lower MMR by three quarters between 1990-2015. Narrative literature review. Study articles from 1996-2012 were searched in electronic databases MEDLINE, Cochrane, PubMED, Google's scholar and manual searches. Combinations of the following search words were used: post-partum haemorrhage/bleeding, sub-Saharan Africa/rural areas, antenatal/obstetric care/maternal mortality/skilled care at birth/maternity care/health survey. 125 article abstracts were read, and 50 full articles used in this review. Every day about 800 women died due to birth complications in 2010: of the 800 maternal deaths worldwide, 440 occurred in sub-Saharan Africa with PPH being the main cause. Common causes of PPH are related to failure of the healthcare system, inaccurate estimation of blood loss after delivery and lack of skills to prevent and manage PPH. Special attention is needed with emphasis on regular attendance of antenatal clinic, proper information concerning pregnancy and delivery, skills to accurate estimate blood loss, and prevention and management of PPH. PPH is the leading cause of MMR in areas where essential care and skilled health attendants are limited. Basic Emergency Obstetric Care and arrangements for timely referral to the big hospital with facilities must be practiced everywhere. This review may help to remind health workers and the government that maternal mortality due to PPH is still higher and more interventions are needed. © 2013 Blackwell Publishing Ltd.

    RIA methods of determining progestorone using the SORIN kit made in Italy and the NEN kit made in Great Britain were compared. Plasma extraction, the initial sample size for examination and recovery, the range of calibration curves of the two kits, the variation coefficient, the values of the blank sample and the values of progesterone determined in the normal menstrual cycle are discussed in detail. Variation coefficient: Sorin (calibration curve 9 to 11%, biological material 9.2%), NEN (calibration curve 12%, biological material 27.8%); determinations of progesterone levels during a normal menstrual cycle were 10 to 15% higher with the NEN kit; tritiated samples were measured with a 30 to 37% efficiency using the SORIN kit and 15 to 18% efficiency using the NEN kit. The turbidity and later sediment which formed during the determination of steroid hormones in biological materials after the addition of the scintillation solution did not reduce the efficiency of measurement. Priority is given to the SORIN kit. (L.O.)

    The purpose of this work was to study the modulation of radiation-induced cell death of human mammary tumoral cells by progesterone. On the one hand, we observed that progesterone protects cells against radiation-induced apoptosis and increases the proportion of surviving and proliferating damaged cells. On the other hand, a transcriptome analysis was undertaken in irradiated cells treated by progesterone, using DNA micro-arrays. This let us highlight several transcriptional dis-regulations that are likely to explain the protective effect of the hormone; in particular, we showed that progesterone regulates the expression of genes implicated in apoptosis signaling by death receptors. Knowing the crucial role of hormonal control and of apoptosis regulation in breast cancer initiation, our results may help to achieve a better understanding of the implication of progesterone in mammary carcinogenesis.

    The objective of this research was to study possible interactions of pseudorabies virus growth factor (PRGF) with ovarian tissue. Granulosa cells isolated from porcine ovaries were cultured as monolayers for 6 days in a control medium without PRGF and in medium supplemented with different doses of this agent. Increased population density and change towards more fibroblastic-like shape of cells cultured with 10(9) I.U PRGF was observed when compared with control culture. The cells divided significantly faster during 6 days of culture under the influence of 10(3), 10(4), 10(5), 10(6), 10(7), 10(8) and 10(9) I.U./ml of PRGF at a dose dependent manner. PRGF in a dose 10(9) I.U. added to cultured cells isolated from small and medium follicles did not influence progesterone secretion . An increase of progesterone secretion under the influence of PRGF in all investigated days of cultures was observed in cells isolated from large preovulatory follicles. The marked increase in progesterone content in PRGF treated culture in doses of 0.5x10(7), 0.5x10(8), 0.5x10(9) I.U. was observed during 4 and 6 days of culture. The rise of progesterone content was not connected with increased number of secretory cells, but with a stimulation of production per cell. PRGF exerted no visible effect on progesterone secretion by granulosa cells from small and medium follicles cultured for 6 days. The presented in vitro data provide evidence for a local action of PRGF in the follicle depending on the stage of follicular development and duration of exposure.

    During the postpartum period, women are at higher risk of developing a mental disorder such as postpartum depression (PPD), a disorder that associates with mother-infant bonding and child development. Oxytocin is considered to play a key role in mother-infant bonding and social interactions and altered oxytocin plasma concentrations were found to be associated with PPD. In the present study, we evaluated oxytocin plasma levels and depressive symptoms during pregnancy and the postpartum period in healthy women. We evaluated 100 women twice during pregnancy (weeks 35 and 38) and three times in the postpartum period (within 2 days and 7 weeks and 6 months after delivery) by measuring oxytocin plasma levels with enzyme-linked immunosorbent assay (ELISA) and assessing depressive symptoms with the Montgomery-Asberg Depression Rating Scale. Oxytocin plasma levels significantly increased from the 35th week of gestation to 6 months postpartum in all women. However, levels decreased from the 38th week of gestation to 2 days after delivery in participants with postpartum depressive symptoms, whereas they continuously increased in the group without postpartum depressive symptoms; the difference between the course of oxytocin levels in the two groups was significant (Δt2-t3: t = 2.14; p = 0.036*). Previous depressive episodes and breastfeeding problems predicted postpartum depressive symptoms. Our results indicate that alterations in the oxytocin system during pregnancy might be specific for women who develop postpartum depressive symptoms. Future studies should investigate whether oxytocin plasma levels might have predictive value in women at high risk for PPD.

    A sensitive, specific and accurate radioimmunoassay of progesterone in human saliva is described, using /sup 3/H. The assay had a sensitivity of 8 pg/tube and blanks were negligible. The intra- and inter-assay coefficients of variation were 5.2 and 9.4%, respectively. The mean recovery from 60 samples was 93.2 +- 6.3%. Results obtained from nine healthy, normally menstruating women showed that salivary progesterone rose from the 4th day before ovulation to a mean peak (+- SD) of 1.14 +- 0.17 ng/ml on the 8th day after ovulation, followed by a gradual decline. Correlation of salivary and simultaneously obtained plasma progesterone levels was good (r = 0.47; P < 0.001), although the maximum percent increase in salivary progesterone was more than 10 times greater than that of plasma progesterone. Salivary progesterone is thought to reflect the unbound fraction of plasma progesterone and this non-invasive technique can be used for serial investigations in which frequent samplings are required.

    Objective To measure stigma associated with four types of postpartum depression therapies and to estimate the association between stigma and the acceptance of these therapies for black and white postpartum mothers. Methods Using data from two postpartum depression randomized trials, this study included 481 black and white women who gave birth in a large urban hospital and answered a series of questions at 6-months postpartum. Survey items included socio demographic and clinical factors, attitudes about postpartum depression therapies and stigma. The associations between race, stigma, and treatment acceptability were examined using bivariate and multivariate analyses. Results Black postpartum mothers were less likely than whites to accept prescription medication (64 vs. 81%, p = 0.0001) and mental health counseling (87 vs. 93%, p = 0.001) and more likely to accept spiritual counseling (70 vs. 52%, p = 0.0002). Women who endorsed stigma about receipt of postpartum depression therapies versus those who did not were less likely to accept prescription medication, mental health and spiritual counseling for postpartum depression. Overall black mothers were less likely to report stigma associated with postpartum depression therapies. In adjusted models, black women versus white women remained less likely to accept prescription medication for postpartum depression (OR = 0.42, 95% CI 0.24-0.72) and stigma did not explain this difference. Conclusions Although treatment stigma is associated with lower postpartum depression treatment acceptance, stigma does not explain the lower levels of postpartum depression treatment acceptance among black women. More research is needed to understand treatment barriers for postpartum depression, especially among black women.

    In the post-partum period the immune alterations are associated with the multiple autoimmune diseases relapse. After birth, immune-tolerance variation slowly disappear, and is observed a return to a normal state - after an exacerbation period - of autoimmune reactivity, during which a great increase in T cells and autoantibodies is observed. In this period - 3 to 9 months after birth - the thyroid autoimmune disease relapses or reappears. The reactivation of the immune system in the post-partum period unchains an acute phase of celular destruction which characterizes the post-partum thyroiditis.

    Purification of the radioiodinated progesterone tyrosine methyl ester conjugate by gel filtration and the development, optimization and clinical validation of a direct radioimmunoassay (RIA) of progesterone using this radiotracer are described. High purity radiotracer is essential for the error free performance of any RIA. Progesterone 11α hemisuccinate was conjugated to tyrosine methyl ester (TME) by the mixed anhydride method and this conjugate was then radioiodinated by the chloramine-T method. Purification of the radioiodinated product was carried out by gel filtration. About 12 batches of the radiotracer were prepared and purified. The purification by gel filtration gave reproducible elution pattern and purity. The radiotracer thus purified was found to have consistent quality as compared to that of any other purification methods. Non-specific binding of the radiotracer was found to be 95% as checked by paper electrophoresis. The stability (retention of the immunoreactivity) of the radiotracer was two to three months. No appreciable changes in the assay characteristics were observed during this period. The assay involved 3 hours incubation of progesterone antibody with individual standards or sample and radiotracer at room temperature. The optimized assay was then validated for internal and external quality control parameters. A RIA kit was then formulated with this radiotracer for estimation of progesterone in serum. The assay kit consisted of lyophilized individual standards ranging from 0.25 to 50 ng/ml. The clinical performance of the developed kit was compared with that of a commercial ELISA kit and a correlation of 0.94 was observed. (author)

    Body condition score is used as a management tool to predict competency of reproduction in beef cows. Therefore, a retrospective study was performed to evaluate association of BCS at calving with subsequent pregnancy rate, days to first postpartum ovulation, nutrient status (assessed by blood metabolites), and calf BW change in 2- and 3-yr-old cows (n = 351) managed and selected to fit their environment of grazing native range over 6 yr at the Corona Range and Livestock Research Center, Corona, NM. Cows were managed similarly before calving, without manipulation of management, to achieve predetermined BCS at parturition. Palpable BCS (scale of 1 to 9) were determined by 2 experienced technicians before calving. Cows were classified to 1 of 3 BCS groups prior calving: BCS 4 (mean BCS = 4.3 ± 0.02), 5 (mean BCS = 5.0 ± 0.03), or 6 (mean BCS = 5.8 ± 0.06). Cows were weighed weekly after calving and serum was collected once weekly (1 yr) or twice weekly (5 yr) for progesterone analysis to estimate first postpartum ovulation beginning 35 d postpartum. Year effects also were evaluated, with years identified as either above or below average precipitation. Days to first postpartum ovulation did not differ among calving BCS groups (P = 0.93). Pregnancy rates were not influenced by calving BCS (P = 0.83; 92%, 91%, 90% for BCS 4, 5, and 6, respectively). Days to BW nadir was not influenced by BCS at calving (P = 0.95). Cow BW was different at all measuring points (P score did not influence overall pregnancy rates, indicating that young cows can have a reduced BCS and still be reproductively punctual. Therefore, these results indicate that reproductive performance of young cows with reduced BCS may not be affected when managed in extensive range conditions.

    2004-10-01

    The purpose of this work was to study the modulation of radiation-induced cell death of human mammary tumoral cells by progesterone. On the one hand, we observed that progesterone protects cells against radiation-induced apoptosis and increases the proportion of surviving and proliferating damaged cells. On the other hand, a transcriptome analysis was undertaken in irradiated cells treated by progesterone, using DNA micro-arrays. This let us highlight several transcriptional dis-regulations that are likely to explain the protective effect of the hormone; in particular, we showed that progesterone regulates the expression of genes implicated in apoptosis signaling by death receptors. Knowing the crucial role of hormonal control and of apoptosis regulation in breast cancer initiation, our results may help to achieve a better understanding of the implication of progesterone in mammary carcinogenesis.

    This prospective study was carried out in a service hospital, with the aim to study the prevalence and incidence of depression in pregnancy and postpartum period. Eighty Four consecutive patients attending the antenatal outpatient in the Obstetrics & Gynaecology department in their last trimester of pregnancy were recruited for the study. They were assessed on Beck Depression Inventory thrice viz. during third trimester of pregnancy, within 3 days of delivery (early postpartum period) & within 4-8 weeks of delivery (late postpartum period).The prevalence of depression was 8.3%, 20% and 12.8% respectively at three ratings. The incidence was 16% and 10% in the early & late postpartum period respectively. Further analysis revealed that depression in pregnancy correlated significantly with depression in early postpartum period, but not with late postpartum period. Depression in early postpartum period correlated with depression in late postpartum period.These findings have implications for early detection and care of women at risk for developing depression.

    Hair progesterone contents during gestasion and milk progesterone levels during oestrus cycle in Saanen(S), crosses F 1 (SXChengdu Mah) and F 2 (SX(SXChengdu Mah)) goats were determined using the RIA kit. The results showed that progesterone in goats hair could be detected using the RIA kit. In pregnant goats, hair progesterone contents was correlated with the milk progesterone profile during 1-28 days after oestrus (r=0.5458, p<0.01). In non-pregnant goats, similar correlation was observed (r=7832, p<0.01). After milk samples were collected 22 days, 3.9ng/ml of progesterone was taken as the discriminatory level, and precision of pregnancy and non-pregnancy diagnosis were 82.4% and 100% respectively. After hair samples were collected 22 days, 3.7ng/50mg of progesterone was taken as discriminatory level, and precision of pregnancy and non-pregnancy diagnosis were 77.8% and 100% respectively. During gestation, hair progesterone content increased gradually from day 30(5.67±0.98ng/50mg hair)to day 120 (9.85±1.20ng/50mg) and decreased rapidly from -8(before parturition, 7.73±1.91ng/50mg) to day 0(parturition, 4.93±0.25ng/50mg)

    This study investigated whether melatonin protects luteinized granulosa cells from reactive oxygen species (ROS) as an antioxidant to enhance progesterone production in the follicle during ovulation. Follicular fluid was sampled at the time of oocyte retrieval in women undergoing in vitro fertilization and embryo transfer (IVF-ET). Melatonin concentrations in the follicular fluid were positively correlated with progesterone concentrations (r = 0.342, P progesterone and 8-OHdG concentrations were negatively correlated (r = -0.246, P Progesterone production by luteinized granulosa cells was significantly inhibited by H(2)O(2). Melatonin treatment overcame the inhibitory effect of H(2) O(2) . Twenty-five patients who had luteal phase defect (serum progesterone concentrations progesterone concentrations (>10 ng/mL during the mid-luteal phase) in nine of 14 women (64.3%), whereas only two of 11 women (18.1%) showed normal serum progesterone levels in the control group. In conclusion, melatonin protects granulosa cells undergoing luteinization from ROS in the follicle and contributes to luteinization for progesterone production during ovulation. © 2011 John Wiley & Sons A/S.

    Bipolar electrocautery is an effective and commonly used haemostatic technique but it may also cause iatrogenic brain trauma due to thermal injury and secondary inflammatory reactions. Progesterone has anti-inflammatory and neuroprotective actions in traumatic brain injury. However, its potential use in preventing iatrogenic brain trauma has not been explored. We conducted a pilot animal study to investigate the effect of systemic progesterone on brain cellular responses to electrocautery-induced injury. Adult male Sprague-Dawley rats received standardized bipolar electrocautery (40 W for 2 seconds) over the right cerebral cortex. The treatment group received progesterone intraperitoneally 2 hours prior to surgery; the control group received the drug vehicle only. Immunohistochemical studies showed that progesterone could significantly reduce astrocytic hypertrophy on postoperative day 1, 3 and 7, as well as macrophage infiltration on day 3. The number of astrocytes, however, was unaffected. Our findings suggest that progesterone should be further explored as a neuroprotective agent against electrocautery-induced or other forms of iatrogenic trauma during routine neurosurgical procedures. Future studies may focus on different dosing regimens, neuronal survival, functional outcome, and to compare progesterone with other agents such as dexamethasone. Copyright © 2013 Elsevier Ltd.

    2016-07-01

    To briefly describe the postpartum practices among the three major ethnic groups in Malaysia and to identify commonalities in their traditional postpartum beliefs and practices. This narrative review collated information on traditional postpartum practices among Malaysian mothers through a literature search for published research papers on traditional postpartum practices in Malaysia. This review shows that Malaysian mothers have certain postpartum practices that they considered to be important for preventing future ill health. Despite the perceived differences in intra-ethnic postpartum practices, most Malaysian mothers, although from different ethnicities, share similarities in their postpartum regimens and practices in terms of beliefs and adherence to food taboos, use of traditional postpartum massage and traditional herbs, and acknowledgment of the role of older female family members in postpartum care. Health care providers should be aware of multiethnic traditional postpartum practices and use the commonalities in these practices as part of their postpartum care regimen.

    The principal objective of this study was to determinate the post-partum ovarian activity in milking cows of high and low production in one farm of ecuadorian highland. For this experiment was necessary to use 48 animals between second and sith calving, the milk samples were collected according one pre-stablished protocol and the same was: one sample 5th or 6th days, twice a week until the cows were pregnacy and 180 days after parturitium if the cow is open. Additional data were compiled in each farm and both the results of the progesterone by RIA were used to determinate the diferents reproductive parameters in the post-partum of the cows. The most of reproductives parameters in the post-partum of the cows in the both group didn't have significance but the conception rate, services per conception, number of pregnacy cows and percentaje of non visibles heats had one high significance between the treatments.

    Family physicians are uniquely situated to play a major role in postpartum care. Postpartum issues that should be monitored and addressed include reproductive and contraceptive planning, breastfeeding counseling and support, and maternal mental health. All women should be screened for postpartum depression using a validated tool at the postpartum visit and/or at well-child visits. Patients with positive screening results should be offered support and treatment. Women are more likely to breastfeed if they are provided with breastfeeding support and counseling routinely during the prenatal and postpartum periods. All women should be asked about their reproductive life plans, counseled about potential risks associated with short and prolonged interpregnancy intervals, and offered contraception.

    Full Text Available The purpose of this research was the study of reproductive performance in postpartum dairy cows with different parities. Twenty Holstein dairy cows were assigned into two equal primiparous and multiparous groups. Body weight and body condition score (based on 1-5 scoring were measured every other week, starting from two weeks before calving till pregnancy confirmation. Daily milk yield was also recorded. Reproductive parameters including days from calving to the uterus returning time, to the initiation time of clinical oestrus signs, to the first time of insemination and number of insemination per pregnancy were recorded. Meanwhile, blood serum concentrations of estrogen and progesterone were measured. Results indicated that, the mean (±SE of body weight and milk production was significantly higher for multiparous cows. Blood serum concentration of estrogen (mean ±SE was significantly lower for primiparous cows (61.86±17.91 vs. 71.39±17.02 pg/ml. The number of insemination per pregnancy and estrus frequency did not differ between both groups. However, the intervals (mean ±SE of calving to the uterus returning time (40.0±5.41 vs. 24.0±5.41 days, to the first insemination (119.62±14.17 vs. 67.5±14.17 days and the initiation of clinical oestrus signs (28.5±4.5 vs. 19.67±8.5 days was significantly higher for primiparous than multiparous cows. In general, this study demonstrated that the effect of parity on postpartum reproductive performance is modulated through its effect of blood serum estrogen level, uterus returning time and estrus initiation time.

    Full Text Available Dietary supplementation of lactating cows with fat can alter the profiles of key reproductive hormones and boost postpartum energy balance. However, published data under Australian pasture-based dairy production conditions are scanty and inconsistent. Therefore, the objective of this study was to determine whether dietary inclusion of crude degummed canola oil (CDCO at incremental levels for eight-weeks will have significant influence on progesterone (P4, luteinizing hormone (LH and follicle stimulating hormone (FSH of primiparous Holstein–Friesian cows grazing pastures. We tested the hypothesis that postpartum supplementation of primiparous Holstein–Friesian cows with dietary CDCO in a pasture-based system will alter the concentrations of P4, LH and FSH reproductive hormones. A random allocation of twenty primiparous Holstein–Friesian cows into four treatment groups that consisted of a wheat-based pelleted basal diet with no supplemental CDCO (control, or a wheat-based pelleted basal diet with CDCO added at 25 ml/kg (low, 35 ml/kg (medium and 50 ml/kg (high was employed in an eight-week feeding trial after two weeks of adjustment. Supplementation levels of CDCO and week of data collection were significant sources of variation (P  0.05. It was apparent that cows in the high (0.459 ng/ml, medium (0.367 ng/ml and low (0.251 ng/ml levels of oil treatments had higher mean plasma FSH concentrations compared to the control (0.172 ng/ml cows. It was concluded that the current levels of CDCO can be used in pasture-based dairy systems to increase FSH, but not LH and P4.

    Progesterone is a mammalian hormone that has also been discovered in plants but its physiological function in plants is not explained. Experiments using inhibitors of progesterone synthesis and binding would be useful in studies on the significance of this compound in plants. Until now, trilostane and mifepristone have been used in medical sciences as progesterone biosynthesis and binding inhibitors, respectively. We tested these synthetic steroids for the first time in plants and found that they reduced the content of progesterone in wheat. The aim of further experiments was to answer whether the potential disturbances in the production/binding of progesterone, influence resistance to environmental stress (drought) and the development of wheat. Inhibitors and progesterone were applied to plants via roots in a concentration of 0.25-0.5mg/l water. Both inhibitors lowered the activity of CO2 binding enzyme (Rubisco) in wheat exposed to drought stress and trilostane additionally lowered the chlorophyll content. However, trilostane-treated plants were rescued by treatment with exogenous progesterone. The inhibitors also modulated the development of winter wheat, which indicated the significance of steroid regulators and their receptors in this process. In this study, in addition to progesterone and its inhibitors, brassinosteroid (24-epibrassinolide) and an inhibitor of biosynthesis of brassinosteroids were also applied. Mifepristone inhibited the generative development of wheat (like 24-epibrassinolide), while trilostane (like progesterone and an inhibitor of biosynthesis of brassinosteroids) stimulated the development. We propose a model of steroid-induced regulation of the development of winter wheat, where brassinosteroids act as inhibitors of generative development, while progesterone or other pregnane derivatives act as stimulators.

    The methoxychlor metabolite, HPTE, was shown to inhibit P450-cholesterol side-chain cleavage (P450scc) activity resulting in decreased progesterone production by cultured ovarian follicular cells in previous studies. It is not known whether HPTE has any effect on progesterone formation by the corpus luteum. Exposure to 100 nM HPTE reduced progesterone production by luteal cells with progressive declines to progesterone formation and P450scc catalytic activity of hCG- or 8 Br-cAMP-stimulated luteal cells. However, HPTE did not alter mRNA and protein levels of P450scc. Compounds acting as estrogen (17 β-estradiol, bisphenol-A or octylphenol), antiestrogen (ICI) or antiandrogen (monobutyl phthalate, flutamide or M-2) added alone to luteal cells did not mimic the action of HPTE on progesterone and P450scc activity. These results suggest that HPTE directly inhibits P450scc catalytic activity resulting in reduced progesterone formation, and this action was not mediated through estrogen or androgen receptors.

    Progesterone has long been linked to breast cancer but its actual role as a cancer promoter has remained in dispute. Previous in vitro studies have shown that progesterone is converted to 5α-dihydroprogesterone (5αP) in breast tissue and human breast cell lines by the action of 5α-reductase, and that 5αP acts as a cancer-promoter hormone. Also studies with human breast cell lines in which the conversion of progesterone to 5αP is blocked by a 5α-reductase inhibitor, have shown that the in vitro stimulation in cell proliferation with progesterone treatments are not due to progesterone itself but to the metabolite 5αP. No similar in vivo study has been previously reported. The objective of the current studies was to determine in an in vivo mouse model if the presumptive progesterone-induced mammary tumorigenesis is due to the progesterone metabolite, 5αP. BALB/c mice were challenged with C4HD murine mammary cells, which have been shown to form tumors when treated with progesterone or the progestin, medroxyprogesterone acetate. Cells and mice were treated with various doses and combinations of progesterone, 5αP and/or the 5α-reductase inhibitor, finasteride, and the effects on cell proliferation and induction and growth of tumors were monitored. Hormone levels in serum and tumors were measured by specific RIA and ELISA tests. Proliferation of C4HD cells and induction and growth of tumors was stimulated by treatment with either progesterone or 5αP. The progesterone-induced stimulation was blocked by finasteride and reinstated by concomitant treatment with 5αP. The 5αP-induced tumors expressed high levels of ER, PR and ErbB-2. Hormone measurements showed significantly higher levels of 5αP in serum from mice with tumors than from mice without tumors, regardless of treatments, and 5αP levels were significantly higher (about 4-fold) in tumors than in respective sera, while progesterone levels did not differ between the compartments. The results indicate that

    The investigation was carried out on 677 Holstein-Friesian dairy cows from one big commercial farm in Voivodina. The accuracy of the application of serum progesterone RIA for the early diagnosis of non-pregnancy was 98% (and 97% for milk progesterone samples). The figures were 49% and 60%, respectively, for positive diagnosis. The high percentage of false positive results was probably due to a high incidence of disturbances in the oestrous cycle and problems of heat detection. Investigation of progesterone profiles in post-partum dairy cows showed that the duration of post-partum anoestrous was strongly influenced by the level of nutrition. Treatment with GnRH suggested that two injections of GnRH given 15 d and 23 d post-partum could induce the onset of the first ovulation. (author). 15 refs, 9 figs, 4 tabs

    This investigation describes a scaling up study aimed at producing progesterone containing nanoparticles in a pilot scale. Particularly hot homogenization techniques based on ultrasound homogenization or high pressure homogenization have been employed to produce lipid nanoparticles constituted of tristearin or tristearin in association with caprylic-capric triglyceride. It was found that the high pressure homogenization method enabled to obtain nanoparticles without agglomerates and smaller mean diameters with respect to ultrasound homogenization method. X-ray characterization suggested a lamellar structural organization of both type of nanoparticles. Progesterone encapsulation efficiency was almost 100% in the case of high pressure homogenization method. Shelf life study indicated a double fold stability of progesterone when encapsulated in nanoparticles produced by the high pressure homogenization method. Dialysis and Franz cell methods were performed to mimic subcutaneous and skin administration. Nanoparticles constituted of tristearin in mixture with caprylic/capric triglyceride display a slower release of progesterone with respect to nanoparticles constituted of pure tristearin. Franz cell evidenced a higher progesterone skin uptake in the case of pure tristearin nanoparticles. A human in vivo study, based on tape stripping, was conducted to investigate the performance of nanoparticles as progesterone skin delivery systems. Tape stripping results indicated a decrease of progesterone concentration in stratum corneum within six hours, suggesting an interaction between nanoparticle material and skin lipids.

    Ovarian activity and factors influencing it were studied in the Malaysian indigenous goat using plasma progesterone radioimmunoassay technique and laparoscopic examination of the ovaries. Laparoscopy, complemented by progesterone assay, was found to be a reliable technique for diagnosing the presence of corpora lutea (CL). However, progesterone assay had the limitation that it could not detect the presence of early developing CL. Two morphological types of CL were observed, either protruding or embedded. The mean plasma progesterone concentrations for pregnant, dioestrous and postpartum anoestrous goats were 4.8 ± 0.72, 4.7 ± 1.60 and <0.7 ng/mL respectively. An inhibitory effect of suckling on the resumption of postpartum ovarian activity was also observed. Removal of kids tended to hasten the onset of postpartum ovarian activity. Continuous confinement of goats was suspected to contribute to conception failure and non-regression of the CL. Kids fed improved diet showed higher average daily weight gain than those suckling their dams. (author). 12 refs, 3 figs, 7 tabs

The pharmacokinetic parameters of the PNS (6 mg/mL in pluronic F127/MC gel were evaluated in comparison with the control progesterone suspension. After the administration of PNS in F127/MC gel into the rats, a maximum serum concentration of 22.1 ± 1.9 ng/mL was reached at a Tmax of 4.05 ± 0.1 h. The terminal half life was 12.7 ± 0.8 h. The area under the curve AUC0-∞ of the injected formula was 452.75 ± 42.8 ng•h/mL and the total mean residence time was 18.57 ± 1.44 h. The PNS in gel was significantly different from the control in rate and extent at P < 0.001. The natural progesterone which was nanosized and formulated in a thermosensitive gel significantly sustained the action of natural progesterone so that it could be injected every 36 h instead of every day. Moreover, this formula is expected to provide a much safer choice than the use of semi-synthetic progesterone.Keywords: progesterone, nanosuspension, thermosensitive gel, ovariectomized female rats

  14. Bangladesh women report postpartum health problems.

    1994-02-01

    The Bangladesh Rural Advancement Committee conducted operational research in Bangladesh to examine postpartum health problems. Researchers conducted focus groups, indepth interviews, and observation. More than 40% of the postpartum women had a delivery-related health problem by 2 weeks after delivery. 52% had signs or symptoms of anemia. Body needs after pregnancy, lactation, and blood loss during delivery exacerbate the nutritional anemia common to Bangladeshi women. 17% of the postpartum women had signs of infections. More than 50% had severe malnutrition, worsened by food taboos during the postpartum period. 60% of infant deaths occur in the neonatal period. The mortality risk is elevated in low birth weight (LBW) infants. In this study, more than 50% of the newborns were LBW infants. Many Bangladeshi mothers discard the colostrum and begin breast feeding several days after delivery. 11% of the postpartum women had breast problem (e.g., cracked nipples). Women believed that susceptibility to evil spirits accounted for their being more vulnerable to health problems during the postpartum. They feared leaving the household. These findings show a need for home visits to provide valuable postpartum care.

    Research suggests that exclusive breastfeeding may have a stress-protective role in postpartum depression; however, less is known about the underlying mechanisms by which this protection may occur or whether the protective relationship holds for women who mix breast and bottle feeding. To examine patterns of the stress response, inflammation, and depressive symptoms among women predominantly breastfeeding or bottle feeding their infants at 6 months postpartum. A part of a larger longitudinal study across 6 months postpartum investigating the psychoneuroimmunology (PNI) of postpartum depression. Prenatal clinics and community. One hundred nineteen postpartum women who met inclusion/exclusion criteria and followed up from the prenatal period to postpartum 6 months. Data were collected during seven home visits occurring during the 3rd trimester (weeks 32-36) and on postpartum days 7 and 14, months 1, 2, 3, and 6. Women completed stress and depression surveys and provided blood for pro- (IL-1β, IL-6, IL-8, TNF-a, IFN-γ) and anti-inflammatory (IL-10) cytokines, and collected saliva for diurnal cortisol. Self-report of predominant breastfeeding during 6 months postpartum ranged from 91.9% at day 7 to 70.6% at month 6 postpartum. There were no associations between the pattern of feeding and depressive symptoms. Biological differences, however, existed between the groups, with levels of salivary cortisol at 8 AM and 8:30 AM at month 6 higher and levels of IL-6 at month 6 lower in women who primarily breastfed compared to those who primarily bottle fed their infants after controlling for confounding variables. Breastfeeding was not related to postpartum depression however differences in stress and inflammatory markers are apparent at month 6 postpartum. Copyright © 2015 Elsevier Ltd. All rights reserved.

    This meta-analysis assessed the efficacy of a wide range of preventive interventions designed to reduce the severity of postpartum depressive symptoms or decrease the prevalence of postpartum depressive episodes. A systematic review identified 37 randomized or quasi-randomized controlled trials in which an intervention was compared to a control condition. Differences between treatment and control conditions in the level of depressive symptoms and prevalence of depressive episodes by 6 months postpartum were assessed in separate analyses. Depressive symptoms were significantly lower at post-treatment in intervention conditions, with an overall effect size in the small range after exclusion of outliers (Hedges' g = 0.18). There was a 27% reduction in the prevalence of depressive episodes in intervention conditions by 6 months postpartum after removal of outliers and correction for publication bias. Later timing of the postpartum assessment was associated with smaller differences between intervention and control conditions in both analyses. Among studies that assessed depressive symptoms using the EPDS, higher levels of depressive symptoms at pre-treatment were associated with smaller differences in depressive symptoms by 6 months postpartum. These findings suggest that interventions designed to prevent postpartum depression effectively reduce levels of postpartum depressive symptoms and decrease risk for postpartum depressive episodes.

    2016-06-01

    Conclusions: Social changes have an influence on traditional postpartum ritual practices so a postpartum nursing center becomes a choice for postpartum women. Thus, health care professionals should value their own functions and roles at the postpartum nursing center since the new mothers regard them as the primary support resource to help them recover from giving birth. Therefore, they need to re-examine their practices from the postpartum women's perspective to provide better support and sensitive care to postpartum women and their families.

    The influence of unopposed estrogen replacement/isolated progesterone deficiency on macrophage production of pro-inflammatory/anti-inflammatory mediators in the post-reproductive age was studied. Considering that in the rats post-ovariectomy the circulating estradiol, but not progesterone level rises to the values in sham-operated controls, 20-month-old rats ovariectomized at the age of 10 months served as an experimental model. Estrogen and progesterone receptor expression, secretion of pro- and anti-inflammatory cytokines, and arginine metabolism end-products were examined in splenic and peritoneal macrophages under basal conditions and following lipopolysaccharide (LPS) stimulation in vitro. Almost all peritoneal and a subset of splenic macrophages expressed the intracellular progesterone receptor. Ovariectomy diminished cytokine production by splenic (IL-1β) and peritoneal (TNF-α, IL-1β, IL-10) macrophages and increased the production of IL-10 by splenic and TGF-β by peritoneal cells under basal conditions. Following LPS stimulation, splenic macrophages from ovariectomized rats produced less TNF-α and more IL-10, whereas peritoneal macrophages produced less IL-1β and TGF-β than the corresponding cells from sham-operated rats. Ovariectomy diminished urea production in both subpopulations of LPS-stimulated macrophages. Although long-lasting isolated progesterone deficiency in the post-reproductive age differentially affects cytokine production in the macrophages from distinct tissue compartments, in both subpopulations, it impairs the pro-inflammatory/anti-inflammatory cytokine secretory balance. © 2015 John Wiley & Sons A/S.

    Full Text Available Jodie M Dodd, Caroline A CrowtherDiscipline of Obstetrics and Gynaecology, The University of Adelaide, Adelaide, South Australia, AustraliaAbstract: Preterm birth continues to provide an enormous challenge in the delivery of perinatal health care, and is associated with considerable short and long-term health consequences for surviving infants. Progesterone has a role in maintaining pregnancy, by suppression of the calcium–calmodulin–myosin light chain kinase system. Additionally, progesterone has recognized anti-inflammatory properties, raising a possible link between inflammatory processes, alterations in progesterone receptor expression and the onset of preterm labor. Systematic reviews of randomized controlled trials evaluating the use of intramuscular and vaginal progesterone in women considered to be at increased risk of preterm birth have been published, with primary outcomes of perinatal death, preterm birth <34 weeks, and neurodevelopmental handicap in childhood. Eleven randomized controlled trials were included in the systematic review, involving 2714 women and 3452 infants, with results presented according to the reason women were considered to be at increased risk of preterm birth. While there is a potential beneficial effect in the use of progesterone for some women considered to be at increased risk of preterm birth, primarily in the reduction in the risk of preterm birth before 34 weeks gestation, it remains unclear if the observed prolongation of pregnancy translates into improved health outcomes for the infant.Keywords: progesterone, preterm birth, systematic review, randomized trial

    Two proteins, designated as PP12 and PP14 were originally isolated from soluble extracts of the human placenta and its adjacent membranes. We have shown that they are synthesized by decidualized/secretory endometrium and not by placenta. Both proteins occur at high concentrations in human amniotic fluid, which is therefore an excellent source for purification. PP12 is a 34-kDa glycoprotein, which has an N-terminal amino acid sequence of Ala-Pro-Trp-Gln-Cys-Ala-Pro-Cys-Ser-Ala. This is identical with that of somatomedin-binding protein purified from the amniotic fluid. PP12 too binds somatomedin-C, or IGF-I (insulin-like growth factor-I). Human secretory endometrium synthesizes and secretes PP12, and progesterone stimulates its secretion. PP14 is a 28-kDa glycoprotein. Its N-terminal sequence shows homology to that of beta-lactoglobulins from various species. We have found PP14 in the human endometrium, serum and milk. Immunologically, PP14 is related to progestagen-associated endometrial protein (PEP), alpha-2 pregnancy-associated endometrial protein (alpha-2, PEG), endometrial protein 15 (EP15), alpha-uterine protein (AUP) and chorionic alpha-2 microglobulin (CAG-2). In ovulatory menstrual cycles, the concentration of PP14 increases in endometrial tissue as the secretory changes advance. In serum, the PP14 concentration begins to rise later than the progesterone levels, and high serum PP14 levels are maintained for the first days of the next cycle. By contrast, no elevation of serum PP14 level is seen in anovulatory cycles. Our results show that progesterone-associated proteins are synthesized by the human endometrium and appear in the peripheral circulation, where they can be quantitatively measured using immunochemical techniques.

    Steroid hormones are well-recognized suppressors of the inflammatory response, however, their cell- and tissue-specific effects in the regulation of inflammation are far less understood, particularly for the sex-related steroids. To determine the contribution of progesterone in the endothelium, we have characterized and validated an in vitro culture system in which human umbilical vein endothelial cells constitutively express human progesterone receptor (PR). Using next generation RNA-sequencing, we identified a selective group of cytokines that are suppressed by progesterone both under physiological conditions and during pathological activation by lipopolysaccharide. In particular, IL-6, IL-8, CXCL2/3, and CXCL1 were found to be direct targets of PR, as determined by ChIP-sequencing. Regulation of these cytokines by progesterone was also confirmed by bead-based multiplex cytokine assays and quantitative PCR. These findings provide a novel role for PR in the direct regulation of cytokine levels secreted by the endothelium. They also suggest that progesterone-PR signaling in the endothelium directly impacts leukocyte trafficking in PR-expressing tissues. Copyright © 2013 The Authors. Published by Elsevier Inc.

    Full Text Available Background: The effect of elevated progesterone level on human chorionic gonadotropin (HCG day in in vitro fertilization cycles is controversial. Some suppose that rise in progesterone level seems to have a negative impact on implantation and pregnancy by desynchronizing the endometrium, while others disagree. Objective: To evaluate the superiority of the frozen cycle over fresh cycle on live birth in patients with elevated progesterone level on HCG day. Materials and Methods: In this double-blind, randomized clinical trial, 72 women undergoing assisted reproductive technology with elevated progesterone level (≥1.8 ng/dl on HCG day were included. The participants were grouped by fresh versus frozen embryo transfer, randomly. Finally, the clinical pregnancy and live birth rate were compared. Results: The implantation rate was 21.51%. The clinical pregnancy rate was 47.22% in fresh embryo transfer group (17/36 and 41.66% in frozen group (15/36 (p=0. 40. The live birth rate was not significantly difference between two groups (p=0.56. Conclusion: None of the fresh and frozen cycles are superior to the other and we recommend individualizing the decision for each patient. The frozen cycle may impose more emotional stress on patients

    Full Text Available Clinical data suggest that progestins have chemopreventive properties in the development of colorectal cancer. We set out to examine a potential protective effect of progestins and progesterone signaling on colon cancer development. In normal and neoplastic intestinal tissue, we found that the progesterone receptor (PR is not expressed. Expression was confined to sporadic mesenchymal cells. To analyze the influence of systemic progesterone receptor signaling, we crossed mice that lacked the progesterone receptor (PRKO to the Apc(Min/+ mouse, a model for spontaneous intestinal polyposis. PRKO-Apc(Min/+ mice exhibited no change in polyp number, size or localization compared to Apc(Min/+. To examine effects of progestins on the intestinal epithelium that are independent of the PR, we treated mice with MPA. We found no effects of either progesterone or MPA on gross intestinal morphology or epithelial proliferation. Also, in rats treated with MPA, injection with the carcinogen azoxymethane did not result in a difference in the number or size of aberrant crypt foci, a surrogate end-point for adenoma development. We conclude that expression of the progesterone receptor is limited to cells in the intestinal mesenchyme. We did not observe any effect of progesterone receptor signaling or of progestin treatment in rodent models of intestinal tumorigenesis.

    The standardisation of a direct radioimmunoassay for progesterone using an 125 I labeled progesterone prepared by iodinating the tyrosine methyl ester (TME) conjugated to a progesterone hemiphthalate derivative and an antibody prepared using a progesterone linked to bovine serum albumin through 11α hemisuccinate derivative is described. The hemiphthalate derivative of progesterone was prepared by reacting 11α-hydroxy progesterone with phthalic anhydride which was then conjugated to TME by using isobutyl chloroformate. The conjugate was iodinated with 125 I using chloramine-T as oxidising agent and purified by thin layer chromatography. Radiochemical purity of the tracer was >95% in all batches. The tracer gave 70-75% binding with excess antibody. Assays were optimised with 8-anilino-1-naphthalene sulphonic acid (ANS) and sodium salicylate as blocking agents to release the progesterone from binding proteins. The assays optimised with sodium salicylate as blocking agent has a sensitivity of 0.25 ng/ml and a working range of 0.25-50 ng/ml, whereas the assay with ANS has a sensitivity of 0.75 ng/ml and a working range of 0.75-100 ng/ml. Serum samples were analysed and compared with the values obtained with a homologous bridge assay. (author)

    Scientific studies investigating the postpartum period are scarce, and observational studies greatly outnumber controlled trials. Many studies are biased in their assumptions about the social roles of women and men and in the interpretation of observations and treatment strategies. The published literature is fragmentary; few researchers have attempted a comprehensive, biopsychosocial system-oriented view of postpartum health. More research is needed on the occurrence and treatment of such common postpartum problems as urinary incontinence, sexual dysfunction, and back pain. Widespread application of what is already known about support for breast-feeding, prevention of fatigue and depression, contraception, and maintenance of healthy lifestyles will require innovations in healthcare delivery, professional practices, and social policy, particularly in the occupational arena. Many postpartum problems have been found to be iatrogenic and responsive to changes in the routine care of mothers and newborns. Finally, it is clear that women of lower education and socioeconomic status and those with less social support are consistently at higher risk for postpartum and parenting problems; great benefits are likely from interventions that enhance the well-being of these mothers and infants.

    The aim of this work is to describe the radioimmunological determination of plasma progesterone carried out at the hormonology Laboratory of the Grenoble University Hospital Centre (Professor E. Chambaz), to compare our results with those of the literature and to present the main clinical indications of this analysis. The measurement method has proved reproducible, specific (the steroid purification stage is unnecessary) and sensitive (detection: 10 picograms of progesterone per tube). In seven normally menstruating women our results agree with published values: (in nanograms per millilitre: ng/ml) 0.07 ng/ml to 0.9 ng/ml in the follicular phase, from the start of menstruation until ovulation, then rapid increase at ovulation with a maximum in the middle of the luteal phase (our values for this maximum range from 7.9 ng/ml to 21.7 ng/ml) and gradual drop in progesterone secretion until the next menstrual period. In gynecology the radioimmunoassay of plasma progesterone is valuable for diagnostic and therapeutic purposes: - to diagnosis the absence of corpus luteum, - to judge the effectiveness of an ovulation induction treatment [fr

    National survey data suggest that new mothers have high prevalences of alcohol and illicit drug use. Depression correlates with substance use, and new mothers with postpartum depression (PPD) may be at high risk for substance use. Understanding postpartum substance use and its relationship to PPD can inform future research and intervention. A literature search was conducted resulting in 12 studies published from 1999–2012 examining postpartum alcohol use, drug use, or combined postpartum depression and substance use. Postpartum alcohol (prevalence range 30.1%−49%) and drug use (4.5%–8.5%) were lower than use among not pregnant, not postpartum women (41.5%–57.5%; 7.6%–10.6%, respectively) but higher than use among pregnant women (5.4%–11.6%; 3.7%–4.3%, respectively). Correlates of postpartum problem drinking were being unemployed, unmarried, and a cigarette smoker. Prevalence of drug use was highest among white new mothers, followed by Blacks and Hispanics, but Black new mothers appeared at greater risk of drug use. No identified studies examined correlates of postpartum drug use beyond race/ethnicity. Postpartum depressive symptoms were prevalent among postpartum substance users and those with a substance use history (19.7%–46%). The postpartum period is a critical time. Prevalent substance use and the scarcity of studies warrant research to identify means to reduce maternal substance use. PMID:23879459

    Successful reproduction requires that changes in plasma follicle-stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL), oxytocin (OT), estrogen (E(2)) and progesterone (P(4)) occur together with the display of maternal behaviors. Ovarian steroids and environmental stimuli can affect the dendritic spines in the rat hippocampus. Here, studying Wistar rats, it is described: (a) the sequential and concomitant changes in the hormonal profile of females at postpartum days (PP) 4, 8, 12, 16, 20 and 24, comparing to estrous cycle referential values; (b) the dendritic spine density in the stratum radiatum of CA1 (CA1-SR) Golgi-impregnated neurons in virgin females across the estrous cycle and in multiparous age-matched ones; and (c) the proportion of different types of spines in the CA1-SR of virgin and postpartum females, both in diestrus. Plasma levels of gonadotrophins and ovarian hormones remained low along PP while LH increased and PRL decreased near the end of the lactating period. The lowest dendritic spine density was found in virgin females in estrus when compared to diestrus and proestrus phases or to postpartum females in diestrus (p0.4). There were no differences in the proportions of the different spine types in nulliparous and postpartum females (p>0.2). Results suggest that medium layer CA1-SR spines undergo rapid modifications in Wistar females across the estrous cycle (not quite comparable to Sprague-Dawley data or to hormonal substitutive therapy following ovariectomy), but persistent effects of motherhood on dendritic spine density and morphology were not found in this area.

    Summary Preterm birth is the leading cause of perinatal morbidity and mortality worldwide, and its prevention is an important healthcare priority. Preterm parturition is one of the ‘great obstetrical syndromes’ and is caused by multiple etiologies. One of the mechanisms of disease is the untimely decline in progesterone action, which can be manifested by a sonographic short cervix in the midtrimester. The detection of a short cervix in the midtrimester is a powerful risk factor for preterm delivery. Vaginal progesterone can reduce the rate of preterm delivery by 45%, and the rate of neonatal morbidity (admission to neonatal intensive care unit, respiratory distress syndrome, need for mechanical ventilation, etc.). To prevent one case of spontaneous preterm birth birth in women with a short cervix both with and without a prior history of preterm birth. In patients with a prior history of preterm birth, vaginal progesterone is as effective as cervical cerclage to prevent preterm delivery. 17α-Hydroxyprogesterone caproate has not been shown to be effective in reducing the rate of spontaneous preterm birth in women with a short cervix.

    BACKGROUND: Weight gained during pregnancy and not lost postpartum may contribute to obesity in women of childbearing age. OBJECTIVE: We aimed to determine whether breastfeeding reduces postpartum weight retention (PPWR) in a population among which full breastfeeding is common and breastfeeding...... duration is long. DESIGN: We selected women from the Danish National Birth Cohort who ever breastfed (>98%), and we conducted the interviews at 6 (n = 36 030) and 18 (n = 26 846) mo postpartum. We used regression analyses to investigate whether breastfeeding (scored to account for duration and intensity......) reduced PPWR at 6 and 18 mo after adjustment for maternal prepregnancy body mass index (BMI) and gestational weight gain (GWG). RESULTS: GWG was positively (P postpartum. Breastfeeding was negatively associated with PPWR in all women but those...

  13. The role of progesterone signaling in the pathogenesis of uterine leiomyoma

    Kim, J. Julie; Sefton, Elizabeth C.

    2011-01-01

    Uterine leiomyomas are benign tumors that originate from the myometrium. Evidence points to ovarian steroid hormones, in particular, progesterone as major promoters of leiomyoma development and growth. While progesterone action in leiomyomas involves the classical nuclear receptor effects on gene regulation, there is growing evidence that signaling pathways are directly activated by the progesterone receptor (PR) and that PR can interact with growth factor signaling systems to promote proliferation and survival of leiomyomas. Studies investigating the genomic and non-genomic actions of PR and its role in leiomyoma growth are summarized here. Studies testing various selective progesterone receptor modulators for the treatment of leiomyomas are also highlighted. An increased understanding of the mechanisms associated with progesterone-driven growth of leiomyomas is critical in order to develop more efficient and targeted therapies for this prevalent disease.

    Detailed procedure description of an iodinated progesterone radioimmunoassay system development is reported. Immunization regime with progesterone 11 α-hemisuccinate: BSA gave 1:6000 antibody titre within a period of 6 months. Minimal amount of the immunogen was spent to obtain a stock of the antiserum. Conjugation of progesterone 11 α-hemisuccinate to tyrosine methyl ester using the isobutyl-chloroformate reaction gave a product with less patch to patch variations in tracer characteristics. At home radioiodination with 125 I reduced the expenses drastically and resulted in extended tracer shelf life (up to 3 months). The use of the second antibody method of separating bound from free hormone proved to be more convenient and brought the progesterone radioimmunoassay system to routine work

    Full Text Available This study aimed to identify actual and perceived barriers to postpartum care among a probability sample of women who gave birth in Los Angeles County, California in 2007. Survey data from the 2007 Los Angeles Mommy and Baby (LAMB study (N = 4,075 were used to identify predictors and barriers to postpartum care use. The LAMB study was a cross-sectional, population-based study that examined maternal and child health outcomes during the preconception, prenatal, and postpartum periods. Multivariable analyses identified low income, being separated/divorced and never married, trying hard to get pregnant or trying to prevent pregnancy, Medi-Cal insurance holders, and lack of prenatal care to be risk factors of postpartum care nonuse, while Hispanic ethnicity was protective. The most commonly reported barriers to postpartum care use were feeling fine, being too busy with the baby, having other things going on, and a lack of need. Findings from this study can inform the development of interventions targeting subgroups at risk for not obtaining postpartum care. Community education and improved access to care can further increase the acceptability of postpartum visits and contribute to improvements in women’s health. Postpartum care can serve as a gateway to engage underserved populations in the continuum of women’s health care.

    Full Text Available Thyroid cancer and thyroid nodules are more prevalent in women than men, so female sex hormones may have an etiological role in these conditions. There are no data about direct effects of progesterone on thyroid cells, so the aim of the present study was to evaluate progesterone effects in the sodium-iodide symporter NIS, thyroglobulin TG, thyroperoxidase TPO, and KI-67 genes expression, in normal thyroid follicular cells, derived from human tissue. NIS, TG, TPO, and KI-67 mRNA expression increased significantly after TSH 20 μUI/mL, respectively: 2.08 times, P<0.0001; 2.39 times, P=0.01; 1.58 times, P=0.0003; and 1.87 times, P<0.0001. In thyroid cells treated with 20 μUI/mL TSH plus 10 nM progesterone, RNA expression of NIS, TG, and KI-67 genes increased, respectively: 1.78 times, P<0.0001; 1.75 times, P=0.037; and 1.95 times, P<0.0001, and TPO mRNA expression also increased, though not significantly (1.77 times, P=0.069. These effects were abolished by mifepristone, an antagonist of progesterone receptor, suggesting that genes involved in thyroid cell function and proliferation are upregulated by progesterone. This work provides evidence that progesterone has a direct effect on thyroid cells, upregulating genes involved in thyroid function and growth.

    Different studies have documented an association between periodontal disease and low birth-weight delivery. Hence, knowledge of periodontal status during pregnancy and postpartum is important in order to reduce the risks of both diseases. This study aimed to analyze periodontal status at successive stages of pregnancy and 3-6 weeks postpartum in women with initial periodontal alterations. Ninety-six pregnant women were examined at 8-10 weeks (pregnancy diagnosis, baseline), 21-23 weeks and 34-36 weeks of gestation and at 40 days postpartum to record plaque scores, clinically assessed gingival inflammation and probing depth (mean depth and % sites with depth >3 mm). Bivariate and multivariate analyses were performed. Type 1 (α) error was established at 0.05. Plaque Index increased (p = 0.043) throughout pregnancy (baseline, 42%±0.18); 21-23 weeks, 42.6%±0.14; 34-36 weeks, 45.6%±0.13 and decreased postpartum (44.8%±0-13). Gingival Index increased (ppregnancy (baseline, 56.7%±0.20; 21-23 weeks, 66.36%±0.17; 34-36 weeks, 74.5%±0.18) and decreased postpartum (59.3%±0.21). Probing Depth increased (ppregnancy (baseline, 2.51±0.05; 21-23 weeks, 2.63±0.053; 34-36 weeks 2.81±0.055) and decreased postpartum (2.54±0.049). Percentage of sites with Probing Depth >3 mm increased (ppregnancy (baseline, 17.6%±0.16; 21-23 weeks, 23.9%±0.17; 34-36 weeks, 31.1%±0.17) and decreased postpartum (21.2%±0.17) but remained significantly (pPeriodontal status deteriorates during gestation but improves postpartum.

    Full Text Available To determine the risk factors, course of hospital stay and mortality rate among women with post-partum acute kidney injury (AKI, we studied (of 752 patients with AKI admitted to a tertiary care center during the study period between November 2009 and August 2012 27 (3.59% women with post-partum AKI. The data regarding age, parity, cause of renal failure, course of hospital stay and requirement of dialysis were recorded. Sepsis was the major cause (70.3% of post-partum AKI. Other causes included disseminated intravascular coagulation (55.5%, pre-eclampsia/eclampsia (40.7%, ante- and post-partum hemorrhage (40.7% and 22.2% and hemolytic anemia and elevated liver enzymes and low platelet count syndrome (29.6%; most patients had more than one cause of AKI. We found a very high prevalence (18.5% of cortical necrosis in our study patients. A significant correlation was also found between the creatinine level on admission and the period of onset of disease after delivery. In conclusion, several factors are involved in causing post-partum AKI in our population, and sepsis was the most common of them.

  19. Metabolic level recognition of progesterone in dairy Holstein cows using probabilistic models

    Full Text Available Administration of exogenous progesterone is widely used in hormonal protocols for estrous (resynchronization of dairy cattle without regarding pharmacological issues for dose calculation. This happens because it is difficult to estimate the metabolic level of progesterone for each individual cow before administration. In the present contribution, progesterone pharmacokinetics has been determined in lactating Holstein cows with different milk production yields. A Bayesian approach has been implemented to build two probabilistic progesterone pharmacokinetic models for high and low yield dairy cows. Such models are based on a one-compartment Hill structure. Posterior probabilistic models have been structurally set up and parametric probability density functions have been empirically estimated. Moreover, a global sensitivity analysis has been done to know sensitivity profile of each model. Finally, posterior probabilistic models have adequately recognized cow’s progesterone metabolic level in a validation set when Kullback-Leibler based indices were used. These results suggest that milk yield may be a good index for estimating pharmacokinetic level of progesterone.

    Progesteron is a steroid hormone secreted by the corpus luteum and the adrenal cortex in the hypophise gland. The hormone can be used for monitoring pregnancy and even more for the assessment of the corpus luteum in fertile woman (4). The labelling of progesterone with 125 I was carried out for tracer production in the preparation of Progesterone Kit used in the determination of the progesterone derivate has been done. The labelling was carried out in two steps reaction. First the progesterone derivate was activated using N-methyl morpholine and isobutylchloroformate. The second step was performed by conjugating the labelled 125 I Histamin to the activated progesterone derivate. The labelled compound was purified with HPLC followed with the determination of the chemical purity using electrophorosis, the immunoreactivity controlled with the maximum binding of the zerro standard and the non specific binding using the Progesterone Kit. Experimental results showed that the iodination of Progesterone -11-α-hidroxy hemisuccinate ( 125 I) yield 22.15%, chemical purity 92.30%, the radioimmunoreactivity 51% as maximum binding (for zero standard), with NSB 0.67%, and the spesific activity obtained 7.72 Ci/ g. Validation of the tracer using control (low, medium and high) shows the results as follows : (2.72 ± 0.49)nmol/L for low standard and control (1.2 - 2.5 nmol/L), (11.3 ± 1.15) nmol/L for medium standard and control (6-15 n/mol) and (15.95 ± 5.32 ) nmol/L for high standard and control (10-23 nmol/L). The sensitivity of the assay was (0.70 ± 0.024 nmol/L) for zero standard

    Diabetes mellitus has assumed the role of an epidemic. Previously considered a disease of affluent developed countries, it has become more common in developing countries. Pakistan is included among the countries with a high prevalence of diabetes. In this scenario, postpartum management of a woman with diabetes mellitus becomes more important as in this period counseling and educating a woman is essential. Counselling includes life style modifications to prevent future risks involving all the systems of the body. This review article discusses management of diabetes mellitus in postpartum period, guidelines for postpartum screening of women with gestational diabetes mellitus, risks involved in future life and stresses upon the need of local population based studies. Primary care providers and gynaecologists must realize the importance of postpartum screening for diabetes mellitus and provide relevant information to women as well.

    The various endocrinopathies that may occur during the postpartum period are described. The most important and common is gestational and pre-gestational diabetes, but other less common, and also very important ones, are mentioned such as hypopituitarism (Sheehan's syndrome and lymphocytic hypophysitis) and thyroid disorders, pre-existing (hyperthyroidism and hypothyroidism), or postpartum onset (postpartum thyroiditis and Graves' disease). After describing their characteristics, the emphasis is placed on the proper management of these endocrine diseases, some of them which exclusively appear during the postpartum period.

  3. Versatile action of picomolar gradients of progesterone on different sperm subpopulations.

    Directory of Open Access Journals (Sweden)

    Diego Rafael Uñates

    Full Text Available High step concentrations of progesterone may stimulate various sperm physiological processes, such as priming and the acrosome reaction. However, approaching the egg, spermatozoa face increasing concentrations of the hormone, as it is secreted by the cumulus cells and then passively diffuses along the cumulus matrix and beyond. In this context, several questions arise: are spermatozoa sensitive to the steroid gradients as they undergo priming and the acrosome reaction? If so, what are the functional gradual concentrations of progesterone? Do spermatozoa in different physiological states respond differentially to steroid gradients? To answer these questions, spermatozoa were confronted with progesterone gradients generated by different hormone concentrations (1 pM to 100 µM. Brief exposure to a 10 pM progesterone gradient stimulated priming for the acrosome reaction in one sperm subpopulation, and simultaneously induced the acrosome reaction in a different sperm subpopulation. This effect was not observed in non-capacitated cells or when progesterone was homogeneously distributed. The results suggest a versatile role of the gradual distribution of very low doses of progesterone, which selectively stimulate the priming and the acrosome reaction in different sperm subpopulations.

    Full Text Available The causes of luteal phase progesterone deficiency in polycystic ovary syndrome (PCOS are not known. To determine the possible involvement of hyperinsulinemia in luteal phase progesterone deficiency in women with PCOS, we examined the relationship between progesterone, luteinizing hormone (LH and insulin during the luteal phase and studied the effect of metformin on luteal progesterone levels in PCOS. Patients with PCOS (19 women aged 18-35 years were treated with metformin (500 mg three times daily for 4 weeks prior to the test cycle and throughout the study period, and submitted to ovulation induction with clomiphene citrate. Blood samples were collected from control (N = 5, same age range as PCOS women and PCOS women during the late follicular (one sample and luteal (3 samples phases and LH, insulin and progesterone concentrations were determined. Results were analyzed by one-way analysis of variance (ANOVA, Duncan's test and Karl Pearson's coefficient of correlation (r. The endocrine study showed low progesterone level (4.9 ng/ml during luteal phase in the PCOS women as compared with control (21.6 ng/ml. A significant negative correlation was observed between insulin and progesterone (r = -0.60; P < 0.01 and between progesterone and LH (r = -0.56; P < 0.05 concentrations, and a positive correlation (r = 0.83; P < 0.001 was observed between LH and insulin. The study further demonstrated a significant enhancement in luteal progesterone concentration (16.97 ng/ml in PCOS women treated with metformin. The results suggest that hyperinsulinemia/insulin resistance may be responsible for low progesterone levels during the luteal phase in PCOS. The luteal progesterone level may be enhanced in PCOS by decreasing insulin secretion with metformin.

    Full Text Available Background: Progesterone as a sex steroid hormone is thought to affect and prevent demyelination, but its role in promoting myelin repair is far less investigated. In this study, remyelinating potential of progesterone in corpus callosum was evaluated on an experimental model of MS. Methods: In this experimental study, adult male C57BL/6 mice were fed with 0.2% (w/w cuprizone in ground breeder chow ad libitum for 6 weeks. At day zero, after cuprizone removal, mice were divided randomly into two groups: (a placebo group, which received saline pellet implant, (b progesterone group, which received progesterone pellet implant. Some mice of the same age were fed with their normal diet to serve as the healthy control group. Two weeks after progesterone administration, Myelin content was assessed by Luxol-fast blue staining. The myelin basic protein (MBP and proteolipid protein (PLP expression were assessed using Western blot analysis and the changes in the number of oligodendrocytes and oligodendroglial progenitor cells were assessed by immunohistochemistry (IHC and flow cytometry. Results: Luxol-fast blue staining revealed enhanced remyelination in the progesterone group when compared with the placebo group. Densitometry measurements of immunoblots demonstrated that MBP and PLP proteins contents were significantly increased in the progesterone group compared with the placebo group. Flow cytometry and IHC analysis showed increases in Olig2 and O4 cells in the progesterone group compared with the placebo group. Conclusion: Overall, our results indicate that progesterone treatment can stimulate myelin production and that it may provide a feasible and practical way for remyelination in diseases such as multiple sclerosis.

    Sleep disturbances cause neurobehavioral performance and daytime functioning impairments. Postpartum women experience high levels of sleep disturbance. Thus, the study objective was to describe and explore the relation between neurobehavioral performance and sleep among women during the early postpartum period. Longitudinal field-based study. There were 70 primiparous women and nine nulliparous women in a control group. None. During their first 12 postpartum weeks, 70 primiparous women wore continuous wrist actigraphy to objectively monitor their sleep. Each morning they self-administered the psychomotor vigilance test (PVT) to index their neurobehavioral performance. Nine nulliparous women in a control group underwent the same protocol for 12 continuous weeks. Postpartum PVT mean reciprocal (1/RT) reaction time did not differ from that of women in the control group at postpartum week 2, but then worsened over time. Postpartum slowest 10% 1/RT PVT reaction time was significantly worse than that of women in the control group at all weeks. Despite improvements in postpartum sleep, neurobehavioral performance continued to worsen from week 2 through the end of the study. Across the first 12 postpartum weeks, PVT measures were more frequently associated with percent sleep compared with total sleep time, highlighting the deleterious consequences of sleep disruption on maternal daytime functioning throughout the early postpartum period. Worsened maternal neurobehavioral performance across the first 12 postpartum weeks may have been influenced by the cumulative effects of sleep disturbance. These results can inform future work to identify the particular sleep profiles that could be primary intervention targets to improve daytime functioning among postpartum women, and indicate need for further research on the effectiveness of family leave policies. The time when postpartum women return to control-level daytime functioning is unknown.

    To explore Asian Indian mothers' perspectives of postpartum depression (PPD) and mental health help-seeking behavior. Qualitative exploratory design. Using convenience sampling, postpartum mothers were recruited through flyers posted in public places and on social media sites. Postpartum depression risk was assessed with the Edinburgh Postnatal Depression Scale (EPDS) prior to qualitative interviews. Content analysis methods were used to extract themes from participant narratives. Twelve self-identified, married, Asian Indian mothers, aged between 29 and 40 years, living in Northern California, who gave birth to a healthy infant within the last 12 months, took part in this study. Scores on the EPDS indicated two participants were at an increased risk for developing PPD. Content analysis revealed two emerging themes: (1) Culture-specific postpartum practices and ceremonies and their role in maternal-infant postpartum recovery; and (2) Maternal mental health help-seeking behavior. Nurses taking care of women during the extended prenatal and postpartum period have the unique opportunity to build rapport with their patients which can offer a window of opportunity to educate and help dispel myths about PPD symptoms and treatment. To promote successful maternal-infant outcomes, PPD education should be initiated at the first prenatal appointment, continue during the pregnancy, and be incorporated into well-baby visits through the first postpartum year. Education should include signs and symptoms of PPD as well as importance of timely mental-health help-seeking.

    The purpose of this study was to explore how traditional ritual practices are incorporated into the context of contemporary healthcare. An ethnographic study was conducted, using observations and interviews with 27 first-time mothers and 3 nurses at a postpartum nursing center in Taipei, Taiwan. Nursing routines, policies and care provision at the center affected the way traditional ritual practices were conducted. New mothers in this study constructed their everyday activities at the center by incorporating and modifying the ritual practices inside and outside the postpartum nursing center setting. Social changes have an influence on traditional postpartum ritual practices so a postpartum nursing center becomes a choice for postpartum women. Thus, health care professionals should value their own functions and roles at the postpartum nursing center since the new mothers regard them as the primary support resource to help them recover from giving birth. Therefore, they need to re-examine their practices from the postpartum women's perspective to provide better support and sensitive care to postpartum women and their families. Copyright © 2016.

    2017-07-01

    Prenatal sex hormone levels affect physical and behavioral sexual differentiation in animals and humans. Although prenatal hormones are theorized to influence sexual orientation in humans, evidence is sparse. Sexual orientation variables for 34 prenatally progesterone-exposed subjects (17 males and 17 females) were compared to matched controls (M age = 23.2 years). A case-control double-blind design was used drawing on existing data from the US/Denmark Prenatal Development Project. Index cases were exposed to lutocyclin (bioidentical progesterone = C 21 H 30 O 2 ; M W : 314.46) and no other hormonal preparation. Controls were matched on 14 physical, medical, and socioeconomic variables. A structured interview conducted by a psychologist and self-administered questionnaires were used to collect data on sexual orientation, self-identification, attraction to the same and other sex, and history of sexual behavior with each sex. Compared to the unexposed, fewer exposed males and females identified as heterosexual and more of them reported histories of same-sex sexual behavior, attraction to the same or both sexes, and scored higher on attraction to males. Measures of heterosexual behavior and scores on attraction to females did not differ significantly by exposure. We conclude that, regardless of sex, exposure appeared to be associated with higher rates of bisexuality. Prenatal progesterone may be an underappreciated epigenetic factor in human sexual and psychosexual development and, in light of the current prevalence of progesterone treatment during pregnancy for a variety of pregnancy complications, warrants further investigation. These data on the effects of prenatal exposure to exogenous progesterone also suggest a potential role for natural early perturbations in progesterone levels in the development of sexual orientation.

    This thesis is comprised of three studies focusing on severe postpartum haemorrhage (PPH). PPH is a major cause of maternal morbidity and mortality worldwide. Risk factors include retained placenta, prolonged duration of the third stage of labour, previous caesarean section, and operative vaginal...... delivery. Occurrence and development of PPH are, however, unpredictable and can sometimes give rise to massive haemorrhage or even hysterectomy and maternal death. Severe haemorrhage can lead to coagulopathy causing further haemorrhage and requiring substitution with blood transfusions. The aim...... had a cardiac arrest, and a total of 128 women (52%) required a hysterectomy. Hysterectomy was associated with increased blood loss, increased number of blood transfusions, a higher fresh frozen plasma to red blood cell ratio (p=0.010), and an increased number of red blood cells before first platelet...

  11. Radioimmunological progesteron determination in peripheral bovine blood

    Ender, M.

    1974-01-01

    A radioimmunological method of determination of the progesterone level in peripheral bovine blood is described which enables a monitoring of the corpus luteum function under varying conditions. There is no dependence of the corpus luteum function on the pituitary gland after endogenous prolactin inhibition with a synthetic prolactin inhibitor in the oestrus cycle and in the end-phase of gravidity. In hysterectomized animals, however, the inhibition of endogenous LH leads to luteolysis. The release of endogenous LH, induced by the administration of an LH release hormone, causes a short increase in progesterone production in the middle phase of the cycle only. The administration of exogenous glucocorticoids during the oestrus cycle did not influence the corpus luteum function. The method described is used in a field test to determine the right time for artificial insemination. There is a significant difference between the progesterone values of impregnated and non-pregnant animals at 16-18 days after insemination. (BSC/AK) [de

    Administration of a single dose of progesterone following trauma and hemorrhage in progesterone-deficient rats would ameliorate the inflammatory response and hepatocellular damage. A university laboratory. Ovariectomized female Sprague-Dawley rats (250-350 g; Charles River Laboratories, Wilmington, Mass) underwent a 5-cm midline laparotomy (ie, induction of soft tissue trauma), were bled to a mean arterial blood pressure of 35 mm Hg for about 90 minutes, and then were resuscitated using Ringer lactate solution. Progesterone (25 mg/kg of body weight) or vehicle was administered subcutaneously at the end of resuscitation. In additional animals, Kupffer cells were isolated following trauma, hemorrhage, and resuscitation and treated in vitro with progesterone, lipopolysaccharide, or both. Six hours following resuscitation, plasma tumor necrosis factor alpha (TNF-alpha) and interleukin 6 (IL-6) levels and liver myeloperoxidase activity were determined. Hepatocellular function (maximum velocity of indocyanine green clearance [Vmax] and the efficiency of the active transport or Michaelis-Menten constant [Km]) and plasma levels of transaminases were measured 20 hours after resuscitation. Kupffer cell IL-6 and TNF-alpha production were assessed. Plasma levels of TNF-alpha, IL-6, aspartate aminotransferase, and alanine aminotransferase, as well as hepatic myeloperoxidase activity were increased, whereas indocyanine green clearance was depressed in vehicle-treated rats following trauma-hemorrhage. Animals treated with progesterone showed significantly reduced levels of the TNF-alpha, IL-6, and transaminases as well as reduced myeloperoxidase activity in the liver. Progesterone-treated animals showed increased Vmax and Kmax values for indocyanine green. In vitro treatment of Kupffer cells with progesterone decreased TNF-alpha production but did not affect the production of IL-6. Progesterone administration following trauma-hemorrhage ameliorates the proinflammatory response

    The focus of this study was to investigate the effect of subclinical endometritis (scEndo) on ovarian follicular steroid concentrations in early postpartum pasture-fed dairy cows. Mixed-age lactating dairy cows (n = 169) were examined to ascertain uterine health status on d 21 postpartum (±3 d). From this herd, a cohort of scEndo and uninfected cows (n = 47) were selected using uterine cytology to determine scEndo. To ensure cows with scEndo were selected for the study, a conservative threshold [>18% polymorphonuclear (PMN) cells among uterine nucleated cells] was chosen as a selection threshold. Ovarian follicular dynamics were assessed by ultrasonography on d 21, 42, and 63 postpartum. On the latter 2 d, all follicles >4 mm in diameter were ablated, and 4 d later, the largest (F1) and second largest (F2) follicles were measured and their follicular fluid aspirated. Hematological variables and plasma metabolites were measured also on these days to further characterize scEndo cows. On d 21, the prevalence of scEndo was approximately 9% in this herd; by d 42 infections had self-resolved in the majority (81%) of those cows classified as having scEndo on d 21. The scEndo cows had a delayed return to cyclicity; however, no effect was evident on ovarian follicle size or growth rate. Weeks after scEndo had self-resolved and cyclicity was restored, decreased (P = 0.07) testosterone and increased (P = 0.07) cortisol concentrations were evident in F1 follicles of scEndo compared with uninfected cows. Progesterone concentrations of F1 increased (P cows, whereas estradiol, androstendione, and dehydroepiandrosterone concentrations were decreased (P cows. These 3 steroids also differed (P size categories of scEndo but not uninfected cows. On d 21, mean plasma albumin concentration was decreased (P = 0.02) in scEndo cows. In summary, early postpartum scEndo had surprisingly long-term influences on the steroid concentrations of ovarian follicles long after infections had self

    Full Text Available Abstract Background Low levels of light exposure at critical times are thought to cause seasonal affective disorder. Investigators, in studies demonstrating the usefulness of bright light therapy, also have implicated light's role in non-seasonal depression. The precise cause of postpartum depression has not been delineated, but it seemed possible that new mothers would spend reduced time in daylight. The goal of this study was to examine the levels of illumination experienced by postpartum mothers and to discover any relationship between light exposure and mood levels experienced during the postpartum period. Methods Fifteen postpartum women, who did not have any baseline indication of depression, wore a wrist device (Actillume for 72 hours to measure their exposure to light. At the end of the recording period, they completed a self-reported measure of mood. The mean light exposure of these postpartum women (expressed as the 24-hour average logarithm of illumination in lux was compared with that of a representative sample of women of comparable age, residence, and seasonal months of recording. Mood levels were then rank-ordered and tested for correlation with light exposure levels. Results There was no significant difference between the amount of light [log10lux] experienced by postpartum (1.01 SD 0.236 and control women (1.06 SD 0.285. Mood was not correlated with illumination in the postpartum sample. Conclusions Postpartum women in San Diego did not receive reduced light, nor was low mood related to low illumination.

    Objectives of the current experiment were to evaluate plasma concentrations of metabolites and haptoglobin peripartum, uterine health and involution, and follicle growth and resumption of cyclicity of Holstein (HO) and Montbéliarde-sired crossbred cows. Cows (52 HO and 52 crossbred) were enrolled in the study 45 d before expected calving date. Cows had body weight and body condition score recorded on d -45, -14, 0, 1, 28, and 56 relative to calving. Dry matter intake was calculated for a subgroup of cows (25 HO and 38 crossbred) from 6 wk before to 6 wk after calving. Blood was sampled weekly from d -14 to 56 relative to calving for determination of glucose, nonesterified fatty acid, and β-hydroxybutyrate concentrations; from d -7 to 21 relative to calving for determination of haptoglobin concentration; and from d 14 to 56 postpartum for determination of progesterone concentration. Cows were examined at calving and on d 4, 7, 10, and 14 postpartum for diagnosis of postparturient diseases, on d 24 postpartum for diagnosis of purulent vaginal discharge, and on d 42 postpartum for diagnosis of subclinical endometritis. Uteri and ovaries were examined by ultrasonography every 3 d from d 14 to 41 postpartum. Milk yield and composition were measured monthly and yield of milk, fat, protein, and energy-corrected milk were recorded for the first 90 d postpartum. Body weight was not different between Holstein and crossbred cows, but HO cows had reduced body condition score compared with crossbred cows. Even though DMI from 6 wk before to 6 wk after calving tended to be greater for HO cows (16.8 ± 0.7 vs. 15.3 ± 0.5 kg/d), HO cows tended to have more pronounced decline in dry matter intake, expressed in percentage of body weight from d -15 to 0 relative to calving. Energy-corrected milk and nonesterified fatty acid and β-hydroxybutyrate concentrations were not different between breeds. No differences were observed in incidence of retained fetal membranes, metritis, and

    Progesterone and corticotropin-releasing hormone (CRH) have a critical role in pregnancy and labor, as changes related to these hormones are crucial for the transition from myometrial quiescence to contractility. The mechanisms related to their effect differ between humans and other species, thus, despite extensive research, many questions remain to be answered regarding their mediation in human labor. Immune responses to progesterone and CRH are important for labor. Progesterone acts as an i...

    Full Text Available It is becoming clear that steroid hormones act not only by binding to nuclear receptors that associate with specific response elements in the nucleus but also by binding to receptors on the cell membrane. In this newly discovered manner, steroid hormones can initiate intracellular signaling cascades which elicit rapid effects such as release of internal calcium stores and activation of kinases. We have learned much about the translocation and signaling of steroid hormone receptors from investigations into estrogen receptor α, which can be trafficked to, and signal from, the cell membrane. It is now clear that progesterone (P4 can also elicit effects that cannot be exclusively explained by transcriptional changes. Similar to E2 and its receptors, P4 can initiate signaling at the cell membrane, both through progesterone receptor and via a host of newly discovered membrane receptors (e.g., membrane progesterone receptors, progesterone receptor membrane components. This review discusses the parallels between neurotransmitter-like E2 action and the more recently investigated non-classical P4 signaling, in the context of reproductive behaviors in the rodent.

    Most women who quit smoking during pregnancy will relapse postpartum. Previous efforts to prevent postpartum relapse have been unsuccessful at increasing rates of sustained abstinence. To evaluate the relative efficacy of 2 different approaches to prevent postpartum smoking relapse. Pregnant women who recently had quit smoking were recruited before the end of pregnancy. Intervention sessions were conducted through a combination of telephone calls and in-person visits beginning at delivery and continuing through 24 weeks postpartum. Participants completed assessments at the prenatal baseline and at 12, 24, and 52 weeks postpartum. Participants were recruited between March 2008 and December 2012. The dates of the analysis were April 2014 to February 2015. Women received postpartum-adapted, behavioral smoking relapse prevention intervention and were randomly assigned to an enhanced cognitive behavioral intervention that included additional specialized strategies and content focused on women's postpartum concerns about mood, stress, and weight (Strategies to Avoid Returning to Smoking [STARTS]) or a supportive, time and attention-controlled comparison (SUPPORT). Intervention began before delivery and continued through 24 weeks postpartum. The primary outcome was biochemically confirmed sustained tobacco abstinence at 52 weeks postpartum. Secondary outcomes were self-reported mood, levels of perceived stress, and degree of concern about smoking-related weight gain. The study cohort comprised 300 participants (150 randomly assigned to each group). Their mean (SD) age was 24.99 (5.65) years. Overall, 38.0% (114 of 300), 33.7% (101 of 300), and 24.0% (72 of 300) of the sample maintained abstinence at 12, 24, and 52 weeks' postpartum, respectively. There were no differences between the intervention groups in abstinence or time to relapse. Self-reported depressive symptoms and perceived stress significantly improved over time, and improvements were similar for both

    The estrous cycle of 10 intact female wolves, aged 8 months-8 years at the initiation of the study, was characterized in terms of vaginal smears, behavioral observations and serum concentrations of estradiol-17β, progesterone and luteinizing hormone (LH) from January through June. No estrous cycles occurred in these animals between June and December. All were housed with male wolves. Two pups and 1 adult remained anestrous during this interval. One pup and 2 adults produced litters between May 4-6. Four adults exhibited endocrine changes similar to those of the pregnant animals but no litters or signs of abortion were observed. The duration of proestrus was 15.7 ± 1.6 days (X ± SEM, n = 6), of estrus 9.0 ± 1.2 days (n = 4) and of the luteal phase 63 ± 2 days (n = 6). The duration of pregnancy was between 60-65 days. The anestrous females (86 blood samples) had 6 progesterone values between 1-2 ng/ml and the remainder below 1 ng/ml. Their estradiol-17β concentrations varied between 5-20 pg/ml. Values for LH varied between 0.1-2 ng/ml, except for 1 value above 15 ng/ml for each of the 2 anestrous pups on 12 January.The 7 estrous animals (260 samples) included 1 pup and 2 adults that delivered litters. Estradiol-17β varied between 10-20 pg/ml during proestrus, peaked at 30-70 pg/ml late in proestrus and fluctuated between 10-30 pg/ml during pregnancy or the duration of luteal activity in the nonpregnant animals. The preovulatory LH rise, 5-15 ng/ml, extended over 3 days during and immediately following the peak estradiol-17β values. An earlier elevation in LH was observed in 3 of the estrous animals. Progesterone began increasing during the LH surge and peaked 11-14 days later at 22-40 ng/ml. Progesterone concentrations greater than 3 ng/ml were maintained for 56-68 days in 6 of the 7 animals exhibiting estrus. Progesterone concentrations declined at parturition but continued to fluctuate between 0.2-3 ng/ml for 3-6 weeks.

    The purpose of this study was to evaluate prenatal to postnatal changes in first-time parents' physical and mental health, and to describe social and health predictors of parents' postpartum health. This prospective study surveyed 261 expectant fathers and mothers during pregnancy and again at 6 months' postpartum regarding their health, partner, and work characteristics. Postpartum changes in health were evaluated by paired t tests, and predictors of postpartum health were determined using multiple regression analyses. Both fathers and mothers experienced significant postpartum declines in perceived quality of life. In addition, fathers reported an increase in the number of days ill and a decrease in general health and vitality after childbirth. Mothers perceived an increase in vitality despite their diminishing sleep. Parents' postpartum health was associated with mothers' partner satisfaction, fewer illness days, and certain work characteristics, such as total work time and the balance of work between mothers and fathers. Both mothers and fathers experienced declines in health that persisted at least 6 months after the birth of their first child. Notably, postpartum health was associated with partner satisfaction and work characteristics. This information might be used to develop interventions for improving parents' health during this vulnerable time.

    A vulvovaginal discharge following parturition in a bitch is often a cause of concern to owners and clinicians, especially if whelping was complicated in any way. Ultrasonography could potentially distinguish between normal and abnormal postpartum uterine states because the uterine wall and luminal contents can be imaged in detail. Five normal bitches were examined to determine the normal ultrasonographic appearance of the postpartum uterus and the sensitivity of ultrasonography in detecting the involuting uterus, comparing this sensitivity with that of radiography. Ultrasonography was done at 1, 4, 8, 12, 18 and 24 days postpartum, radiography at 1, 4, 8, 12 and 18 days postpartum. By 12 days postpartum, the uterus could not be seen on radiographs, while at 24 days postpartum the uterus was still sonographically identifiable. The ultrasonographic characteristics of the involuting uterus are described

    The postpartum period may be critical for the development of midlife obesity. Identifying factors associated with postpartum weight change could aid in targeting women for healthy lifestyle interventions. Data from Active Mothers Postpartum (AMP), a study of overweight and obese postpartum women (n=450), were analyzed to determine the effect of baseline characteristics, breastfeeding, diet, physical activity, and contraception on weight change from 6 weeks to 12, 18, and 24 months postpartum. The repeated measures mixed model was used to test the association of these effects with weight change. Although mean weight loss was modest (0.49 kg by 24 months), the range of weight change was striking (+21.5 kg to -24.5 kg, standard deviation [SD] 7.4). Controlling only for baseline weight, weight loss was associated with breastfeeding, hormonal contraception, lower junk food and greater healthy food intake, and greater physical activity. Only junk food intake and physical activity were significant after controlling for all other predictors. Eating less healthy foods and being less physically active put overweight and obese women at risk of gaining more weight after a pregnancy.

    Progesterone (hydroxyprogesterone caproate injection and vaginal progesterone) has been shown to reduce preterm birth (PTB) rates by a third among pregnant women at high risk. The purpose of this analysis is to report birth outcomes and medication adherence among Massachusetts Medicaid (MassHealth) members receiving progesterone, evaluate the association between member characteristics and birth outcomes and medication adherence, and compare cost of care with a prior preterm pregnancy. This retrospective cohort study used medical claims, pharmacy claims, and prior authorization (PA) request data for MassHealth members who had a PA submitted for progesterone between January 1, 2011, and March 31, 2015. Members were excluded due to breaks in coverage, progesterone was not indicated for prevention of PTB, and if current gestational week or date of delivery was unavailable. A total of 418 members were screened for inclusion of whom 190 met criteria and 169 filled progesterone. Mean age was 29.2 years (SD = 5.23), and clinical comorbidities were identified in 90.5% of members. Consistent with clinical trials on progesterone effectiveness, 62.1% of members had a term delivery (37 wks of gestation). Among members with prior gestational age at delivery available, the average difference in gestational age between pregnancies was 8.25 weeks (SD = 6.11). In addition, 66.3% of members were adherent to progesterone based on proportion of days covered (PDC) of 0.8 or higher. The overall mean PDC was 0.79 (SD = 0.26). Despite similar birth outcomes in clinical trials and national trends, medication adherence is low in this state Medicaid program. Therefore, members may benefit from adherence support. © 2017 Pharmacotherapy Publications, Inc.

  14. Regulation of uterine progesterone receptors by the nonsteroidal anti-androgen hydroxyflutamide

    1991-01-01

    The authors have recently reported that the anti-androgen hydroxyflutamide causes delayed implantation and exhibits antideciduogenic activity in the rat. The present experiments were conducted to examine whether hydroxyflutamide binds to the uterine progesterone receptors and/or alters the progesterone binding sites in the uterus. Cytosol and nuclear fractions from decidualized rat uterus were incubated with [3H]-R5020 without or with increasing concentrations of radioinert R5020, RU486, dihydrotestosterone, or hydroxyflutamide. From the log-dose inhibition curves, the relative binding affinity of both hydroxyflutamide and dihydrotestosterone was less than 0.1% and 2%, compared with R5020 (100%) for displacing [3H]-R5020 bound to uterine cytosol and nuclear fractions, respectively. Injection of estradiol-17 beta (1 microgram/rat) to ovariectomized prepubertal rats induced a 1.85-fold increase in uterine weight by 24 h. Hydroxyflutamide at 2.5 or 5.0 mg did not significantly alter the estrogen-induced increase in uterine weight. Compared to vehicle alone, estrogen induced an approximately 5-fold increase in uterine cytosolic progesterone binding sites. Hydroxyflutamide at both 2.5- and 5.0-mg doses significantly attenuated the estrogen-induced elevation in uterine progesterone binding sites. These studies demonstrate that hydroxyflutamide does not bind with high affinity to progesterone receptors, but suppresses the estrogen-induced elevation in progesterone receptor levels in the uterus

    Progesterone elevation (PE) during the late follicular phase of controlled ovarian stimulation in fresh embryo transfer in vitro fertilization (IVF)/intracytoplasmic sperm injection cycles has been claimed to be associated with decreased pregnancy rates. However, the evidence is not unequivocal, and clinicians still have questions about the clinical validity of measuring P levels during the follicular phase of stimulated cycles. We reviewed the existing literature aimed at answering four relevant clinical questions, namely (i) Is gonadotropin type associated with PE during the follicular phase of stimulated cycles? (ii) Is PE on the day of human chorionic gonadotropin (hCG) associated with negative fresh embryo transfer IVF/intracytoplasmic sperm injection (ICSI) cycles outcomes in all patient subgroups? (iii) Which P thresholds are best to identify patients at risk of implantation failure due to PE in a fresh embryo transfer? and (iv) Should a freeze all policy be adopted in all the cycles with PE on the day of hCG? The existing evidence indicates that late follicular phase progesterone rise in gonadotropin releasing analog cycles is mainly caused by the supraphysiological stimulation of granulosa cells with exogenous follicle-stimulating hormone. Yet, the type of gonadotropin used for stimulation seems to play no significant role on progesterone levels at the end of stimulation. Furthermore, PE is not a universal phenomenon with evidence indicating that its detrimental consequences on pregnancy outcomes do not affect all patient populations equally. Patients with high ovarian response to control ovarian stimulation are more prone to exhibit PE at the late follicular phase. However, in studies showing an overall detrimental effect of PE on pregnancy rates, the adverse effect of PE on endometrial receptivity seems to be offset, at least in part, by the availability of good quality embryo for transfer in women with a high ovarian response. Given the limitations of

    Progesterone elevation (PE) during the late follicular phase of controlled ovarian stimulation in fresh embryo transfer in vitro fertilization (IVF)/intracytoplasmic sperm injection cycles has been claimed to be associated with decreased pregnancy rates. However, the evidence is not unequivocal, and clinicians still have questions about the clinical validity of measuring P levels during the follicular phase of stimulated cycles. We reviewed the existing literature aimed at answering four relevant clinical questions, namely (i) Is gonadotropin type associated with PE during the follicular phase of stimulated cycles? (ii) Is PE on the day of human chorionic gonadotropin (hCG) associated with negative fresh embryo transfer IVF/intracytoplasmic sperm injection (ICSI) cycles outcomes in all patient subgroups? (iii) Which P thresholds are best to identify patients at risk of implantation failure due to PE in a fresh embryo transfer? and (iv) Should a freeze all policy be adopted in all the cycles with PE on the day of hCG? The existing evidence indicates that late follicular phase progesterone rise in gonadotropin releasing analog cycles is mainly caused by the supraphysiological stimulation of granulosa cells with exogenous follicle-stimulating hormone.

    The researchers' aim was to examine whether it was better to predict new-onset postpartum depression (PPD) during pregnancy or immediately after childbirth. A prospective study conducted in Croatia followed women (N = 272) from the third trimester of pregnancy through the early postpartum period (within the first 3 postpartum days), to 6 weeks postpartum. Questionnaires on depression, anxiety, stress, coping, self-esteem, and social support were administered. Through regression analyses we showed that PPD symptoms could be equally predicted by variables from pregnancy (30.3%) and the early postpartum period (34.0%), with a small advantage of PPD prediction in the early postpartum period.

  19. Childhood conditions influence adult progesterone levels.

    Full Text Available Average profiles of salivary progesterone in women vary significantly at the inter- and intrapopulation level as a function of age and acute energetic conditions related to energy intake, energy expenditure, or a combination of both. In addition to acute stressors, baseline progesterone levels differ among populations. The causes of such chronic differences are not well understood, but it has been hypothesised that they may result from varying tempos of growth and maturation and, by implication, from diverse environmental conditions encountered during childhood and adolescence.To test this hypothesis, we conducted a migrant study among first- and second-generation Bangladeshi women aged 19-39 who migrated to London, UK at different points in the life-course, women still resident in Bangladesh, and women of European descent living in neighbourhoods similar to those of the migrants in London (total n = 227. Data collected included saliva samples for radioimmunoassay of progesterone, anthropometrics, and information from questionnaires on diet, lifestyle, and health. Results from multiple linear regression, controlled for anthropometric and reproductive variables, show that women who spend their childhood in conditions of low energy expenditure, stable energy intake, good sanitation, low immune challenges, and good health care in the UK have up to 103% higher levels of salivary progesterone and an earlier maturation than women who develop in less optimal conditions in Sylhet, Bangladesh (F9,178 = 5.05, p < 0.001, standard error of the mean = 0.32; adjusted R(2 = 0.16. Our results point to the period prior to puberty as a sensitive phase when changes in environmental conditions positively impact developmental tempos such as menarcheal age (F2,81 = 3.21, p = 0.03 and patterns of ovarian function as measured using salivary progesterone (F2,81 = 3.14, p = 0.04.This research demonstrates that human females use an extended period of the life cycle prior

    Only 5 studies have examines resumption of intercourse after childbirth and coital frequency. These studies conducted in Chile, England, the Philippines, Scotland, and Thailand found that 4 to almost 8 weeks is the average duration between childbirth and resumption of intercourse. Yet, they also showed sizable variation in this duration. In Thailand, the first postpartum intercourse occurred between 3 and 21 weeks. Further, during this study, one mother had not yet resumed intercourse. A study in metropolitan Cebu, in the Philippines, included 3080 women. The mean intercourse resumption interval was 4-6 weeks, yet at 2 years 80 women still had not had postpartum intercourse. This study found 10 factors predicting resumption of intercourse: husband present, not breast feeding, resumption of menstruation, young age, some education, children younger than 7 years old, uncrowded home, nuclear family, urba residence, and trained health worker delivering baby. Mean coital frequency among the Thai women was once per week, but this does not indicate typical frequency. In fact, one woman averaged intercourse 3 times/week, while another had her first postpartum intercourse 6 weeks after delivery and not gain until 8 weeks later. Family planning counselors can use coital frequency studies to guide them when advising postpartum women. For example, a women who does not have intercourse frequently and is at 6-12 months postpartum could use the lactational amenorrhea method and condoms. More frequent intercourse and resumption of menstruation requires a more reliable family planning method. A 1988 study found that for the first 6 months postpartum women who breast feed have a lower coital frequency, longer delay before intercourse resumption, reduced sexual interest and enjoyment, more pain during intercourse, and are somewhat more depressed than those who bottle feed.

    To explore the influences on accessibility of compounded progesterone therapy for Australian women. A cross-sectional survey of a stratified sample of Australian women who use progesterone only products using the 'Perspectives on Progesterone' questionnaire. Principle components analysis (PCA) to determine components of access to progesterone treatment and multi-way analysis of variance to compare groups. Women using compounded progesterone were likely to have made at least one lifestyle adaptation (73%), and to have tried and stopped using at least one complementary and alternative medicine therapy (63%) or conventional hormone therapy (41%). PCA revealed six components of access to progesterone treatment: affordable, values natural treatments and is concerned about other treatments, conventionally available, perceived knowledge, values information gathered from a variety of sources, and rural & disadvantaged. The multifaceted nature of progesterone use illustrates that there are multiple aspects to use of non-conventional medicines. Women looking for non-conventional treatment are neither stupid nor uninformed, their understandings, based on experience and research, need to be addressed by health professionals while assessing their condition prior to discussing the risks and benefits of non-conventional medicines. Access to compounded progesterone is multifaceted, and many of the women who use it have tried other treatments first. Despite the clinical ambivalence towards progesterone as an alternative for women who may have tried and rejected other treatments, including conventional hormone therapy, the women described in this paper are using it.

    Two direct radioimmunoassays for progesterone in 50 μL of unextracted serum or plasma with assays involving extraction of serum were compared. The direct assays include the use of either danazol at pH 7.4 or 8-anilino-1-naphthalenesulfonic acid at pH 4.0 to displace progesterone from serum binding-proteins. Progesterone is then assayed by using an antiserum to a progesterone 11α-hemisuccinyl conjugate and the radioligand 125 I-labeled progesterone 11α-glucuronyl tyramine, with separation by double-antibody techniques. Direct assays with either displacing agent gave good analytical recovery of progesterone added to human serum, and progesterone values for patients' specimens correlated well (r > 0.96) with results of assays involving extraction of serum. Precision was similar with each displacing agent over the working range 2.5-100 nmol/L and superior to that of extraction assays. We conclude that these direct assays of progesterone are analytically valid and more robust, precise, and technically convenient than many conventional methods involving extraction of serum

    The estrogen and progesterone receptors which are bound to the cytoplasmic protein of cancer cells were measured in 20 patients with the early breast cancer by means of radioimmunoassay using charcoal. 1) The patients with estrogen receptor positive were 13 (65%) of 20 cases and with progestrone receptor positive were 7 cases (35%) in the early breast cancer. 2) Coexistence of estrogen and progesterone receptor positive was noted in 7 cases (35%). The cases of estrogen receptor positive and progesterone receptor negative were 6 cases (33.3%), while there were no cases of estrogen receptor negative with progesterone receptor positive. 3) Coincidence of estrogen and progesterone negative was noticed in 7 cases (35%). Conclusively it is considered that the measurement of estrogen and progesterone receptors has relevance as predictive value, in the response to hormonal manipulations and chemotherapy for breast cancer patients.

    Shoulder dystocia and postpartum hemorrhage represent two of the most common emergencies faced in obstetric clinical practice, both requiring prompt recognition and management to avoid significant morbidity or mortality. Shoulder dystocia is an uncommon, unpredictable, and unpreventable obstetric emergency and can be managed with appropriate intervention. Postpartum hemorrhage occurs more commonly and carries significant risk of maternal morbidity. Institutional protocols and algorithms for the prevention and management of shoulder dystocia and postpartum hemorrhage have become mainstays for clinicians. The goal of this review is to summarize the diagnosis, incidence, risk factors, and management of shoulder dystocia and postpartum hemorrhage. Copyright © 2017 Elsevier Inc. All rights reserved.

    An experiment was conducted on Damascus does to characterize the oestrous cycle, the activity of the corpus luteum and to determine normal progesterone profiles during different phases of the oestrous cycle using radioimmunoassay. Fifteen indigenous cycling Damascus does were used during the normal breeding season for two consecutive oestrous cycles. Average length of the oestrous cycles was 21.2 ± 1.5 days (range: 19 - 26 days), divided into: 2.9 ± 0.8 days (2 - 5 days), where progesterone level was low averaging 0.69 ± 0.85 nmol l -1 (range: 0.00 - 3.08 nmol l -1 , followed by a sharp increase in progesterone secretion, i.e. presence of active corpora lutea, lasted on average for 15.3 ± 1.4 days (range: 13 - 20 days), with an average progesterone level of 13.4 nmol l -1 (range: 3.26 - 27.98 nmol l -1 ), followed by a sharp decline in progesterone level, i.e. inactive corpora lutea, lasted on average for 3.1 ± 0.6 days (range: 2 - 5 days), with an average progesterone level of 0.68 nmol l -1 (range: 0.00 - 2.81 nmol l -1 ). Maximum progesterone level during the luteal phase averaged 18.67 ± 3.15 nmol l -1 (range: 14.00 - 27.98 nmol l -1 ), occurred on average on 12.2 ± 3.2 days of the oestrous cycle. It was possible, for the first time, to characterize the oestrous cycle of the Damascus doe, and to determine normal progesterone profiles during different phases of oestrous cycle. Based on the results reported above, it is also concluded that progesterone levels under 3.18 nmol l -1 were found on average during 2.9 days at the start of the oestrous cycle and during 3.1 days at the end of the oestrous cycle (follicular phase), and that progesterone levels above 3.18 nmol l -1 were found during the luteal phase lasting on average 15.3 days.

    Blood progesterone concentration is used in several procedures related to the reproduction in the bitch, such as ovulation monitoring, estimating time of parturition, or hypo-luteoidism management. Several techniques are available to evaluate blood progesterone concentration, such as the radioimmunoassay (RIA), the chemiluminescent immunoassay (CLIA), and the enzyme-linked immunosorbent assay (ELISA). The aim of this study was to compare the blood progesterone concentration using these three methods during the periovulatory period of 23 bitches. Vaginal cytology was used to classify cytologic estrus (CE) and cytologic diestrus (CD), and blood samples were collected once during proestrus and every other day between CE and CD. The samples were retrospectively classified in the different phases of the estrus based on CD. Pregnancy rate and gestational length were also recorded. A significant increase of the circulating progesterone during the progression of the estrus was recorded, and there were significant differences in the values when using the different methods, with lesser, intermediate, and greatest values with use of the RIA, CLIA, and ELISA, respectively. There was a high correlation (Pearson's correlation coefficient = 0.978) and substantial strength-of-agreement (Lin's concordance correlation coefficient = 0.966) between values obtained when using CLIA and RIA, while there was a high correlation (Pearson's correlation coefficient = 0.955) but poor strength-of-agreement (Lin's concordance correlation coefficient = 0.866) with use of the ELISA and RIA. The data reported in this study provide evidence that the method used for measuring the blood progesterone concentration during the periovulatory phase of the bitch significantly affected the progesterone values.

    2005-01-01

    Five isolates belonging to five species of the genus Cochliobolus were tested for their ability to transform progesterone. Two species namely C. australiensis and C. tuberculates failed to transform progesterone, C. pallescens produced 11B-hydroxy and 6 (3, 11a-dihydroxy progesterone, while the isolate of C. lunatus produced 11B-hydroxy and 17a-hydroxy progesterone. The isolate of C. spicifer produced four mono hydroxylated products (11a-, 11B- -17a dihydroxy progesterone and dihydro-xylated product 11 a, 17a-dihydroxy progesterone) with the addition of two trihydroxy products namely 11 a, 17a,21-trihydroxy progesterone (epicortisol) and 11/3, 17a, 21-trihydroxy progesterone (cortisol). The transformation pattern of progesterone by C. spicifer was markedly affected by the composition of culture medium, pH value of culture medium and gamma irradiation of the tested isolate. The different transformation products were resolved chromatographically. The identity of each product was established through the determination of m.p, optical rotation and ultraviolet as well as infrared absorption spectra. A comparison of the Rf -values of each product with that of the corresponding reference, using different solvent systems as well as their colours with two spray reagents, was used as a further proof for the identity of the isolated products

    Smith-Nielsen, Johanne

    Background: In three academic articles, this PhD thesis investigates maternal postpartum depression (PPD) as a risk factor for the infant-mother attachment and infant development. Previous studies have been contradictory with respect to the question of whether PPD can have long term effects...... on offspring. This may be due to not differing between when PPD is only occurring in the postpartum period and when effects are also due to ongoing or recurrent depression. However, it may also be due to viewing maternal depression as a unitary construct, and not considering underlying maternal psychological...... difficulties which may moderate potential adverse effects. The present thesis investigates two potential maternal moderators of risk:. Comorbid personality disorder and adult attachment insecurity. Moreover, the question of early environmental effects of PPD versus effects of later or ongoing depression...

    A trial was undertaken on Hereford beef cows to determine the length of their post-partum (pp) anoestrous periods under traditional conditions of feeding and management in Uruguay. Three subsequent trials to shorten pp anoestrus involving early weaning (at 40 days pp), temporary weaning for 72 hours (at 45 days), and temporary weaning for 24 hours combined with GnRH, were run in different parts of Uruguay under different soil and pasture conditions. No treatment differences were found, but cows on improved pastures had shorter pp anoestrous periods (74, 99 and 102 days for the three trials respectively) and higher pregnancy rates (80%, 46% and 55% respectively). It was concluded that the main cause of low reproductive efficiency was poor nutrition and that, under such conditions, no treatment to shorten the pp anoestrus would ever be expected to be successful.

    Full Text Available Abstract Background Paradoxical sleep deprivation (PSD associated with cocaine has been shown to enhance genital reflexes (penile erection-PE and ejaculation-EJ in Wistar rats. Since hypertension predisposes males to erectile dysfunction, the aim of the present study was to investigate the effects of PSD on genital reflexes in the spontaneously hypertensive rat (SHR compared to the Wistar strain. We also extended our study to examine how PSD affect steroid hormone concentrations involved in genital events in both experimental models. Methods The first experiment investigated the effects of PSD on genital reflexes of Wistar and SHR rats challenged by saline and cocaine (n = 10/group. To further examine the impact of the PSD on concentrations of sexual hormones, we performed a hormonal analysis of testosterone and progesterone in the Wistar and in SHR strains. Since after PSD progesterone concentrations decreased in the SHR compared to the Wistar PSD group we extended our study by investigating whether progesterone (25 mg/kg or 50 mg/kg or testosterone (0.5 mg/kg or 1.0 mg/kg administration during PSD would have a facilitator effect on the occurrence of genital reflexes in this hypertensive strain. Results A 4-day period of PSD induced PE in 50% of the Wistar rats against 10% for the SHR. These genital reflexes was potentiated by cocaine in Wistar rats whereas this scenario did not promote significant enhancement in PE and EJ in hypertensive rats, and the percentage of SHR displaying genital reflexes still figured significantly lower than that of the Wistar strain. As for hormone concentrations, both sleep-deprived Wistar and SHR showed lower testosterone concentrations than their respective controls. Sleep deprivation promoted an increase in concentrations of progesterone in Wistar rats, whereas no significant alterations were found after PSD in the SHR strain, which did not present enhancement in erectile responses.

    Urinary incontinence (UI) is a common condition in association with pregnancy. Incident UI in pregnancy or postpartum are significant risk factors for UI later in life. Epidemiological studies on UI during pregnancy and postpartum list numerous variables associated with UI. For women, the main focus is on pelvic floor muscle training to prevent UI. However, several other modifiable risk factors are likely to contribute to prevention of UI during pregnancy and postpartum. This review investigated modifiable risk factors for UI during pregnancy and postpartum and also reviewed randomized controlled trials on prevention of UI in association with pregnancy. Systematic searches for publications until September 2012 on prevention of UI during pregnancy and postpartum were performed. Based on available evidence, the following recommendations to prevent UI during pregnancy and postpartum were made: women should be advised not to smoke before or during pregnancy (grade B), aim at normal weight before pregnancy (grade B), and aim at regaining prepregnancy weight postpartum (grade B). Occasional low-intensity training should be advocated (grade B), and constipation should be avoided during pregnancy (grade B) and postpartum (grade C). Women should be advised to perform pelvic floor muscle training during pregnancy and postpartum (grade A) and to use perineal warm packs during delivery (grade B). Cesarean section to prevent UI cannot be recommended (grade D). If lifestyle recommendations are addressed in association with pregnancy, incidence of UI during pregnancy and postpartum is likely to decrease.

    Full Text Available The purpose of this study was to examine first-time mothers' postpartum stress and its correlates following discharge from the hospital or clinic after vaginal delivery. One hundred and eightythree first-time mothers were enrolled from hospitals and clinics in Kaohsiung City. All first-time mothers reported normal pregnancies and vaginal deliveries, delivered healthy infants at term, and were surveyed during their postpartum periods after discharge from hospitals or clinics. The Hung Postpartum Stress Scale was used to examine first-time mothers' postpartum stress and stressors during their postpartum periods. The top ten postpartum stressors perceived by the women were: “the baby getting sick suddenly”, “the flabby flesh of my belly”, “the unpredictability of the baby's schedule”, “interrupted sleep”, “the shape of the baby's head due to the sleeping position”, “not sleeping enough”, “lack of information regarding infant's growth and development”, “the baby's crying”, “my life is restricted”, and “the baby choking during feeding”. There were no significant differences between the first-time mothers' demographic characteristics and their postpartum stress and its three components (negative body changes, maternal role attainment, lack of social support, respectively. Insight into the study results of first-time mothers' post- partum stress and stressors provides a reference for health professionals that the development of programs and resources addressing primiparous women's unique needs are required.

    The effect of progesterone as a respiratory stimulant in newborn subjects is less known than that in adults. This study investigated the dose-response curve (0, 2, 4, and 8 mg/kg, ip) of progesterone on ventilation in non-anesthetized newborn rats at 4- and 12-days old using plethysmography. Progesterone had no effects in the regulation of normoxic ventilation. However, it enhanced the response to moderate hypoxia (FiO(2) 12%, 20 min) in 4- but not in 12-days old pups. This response was similar between the dose of 4 and 8 mg/kg. These observations suggested that progesterone enhances in age- and dose-dependent manner the hypoxic ventilatory response in newborn rats.

    2016-10-01

    Full Text Available Altered progesterone responsiveness leads to female infertility and cancer, but underlying mechanisms remain unclear. Mice with uterine-specific ablation of GATA binding protein 2 (Gata2 are infertile, showing failures in embryo implantation, endometrial decidualization, and uninhibited estrogen signaling. Gata2 deficiency results in reduced progesterone receptor (PGR expression and attenuated progesterone signaling, as evidenced by genome-wide expression profiling and chromatin immunoprecipitation. GATA2 not only occupies at and promotes expression of the Pgr gene but also regulates downstream progesterone responsive genes in conjunction with the PGR. Additionally, Gata2 knockout uteri exhibit abnormal luminal epithelia with ectopic TRP63 expressing squamous cells and a cancer-related molecular profile in a progesterone-independent manner. Lastly, we found a conserved GATA2-PGR regulatory network in both human and mice based on gene signature and path analyses using gene expression profiles of human endometrial tissues. In conclusion, uterine Gata2 regulates a key regulatory network of gene expression for progesterone signaling at the early pregnancy stage.

  17. Anti-inflammatory effects of progesterone in lipopolysaccharide-stimulated BV-2 microglia.

    Beilei Lei

    Full Text Available Female sex is associated with improved outcome in experimental brain injury models, such as traumatic brain injury, ischemic stroke, and intracerebral hemorrhage. This implies female gonadal steroids may be neuroprotective. A mechanism for this may involve modulation of post-injury neuroinflammation. As the resident immunomodulatory cells in central nervous system, microglia are activated during acute brain injury and produce inflammatory mediators which contribute to secondary injury including proinflammatory cytokines, and nitric oxide (NO and prostaglandin E2 (PGE2, mediated by inducible NO synthase (iNOS and cyclooxygenase-2 (COX-2, respectively. We hypothesized that female gonadal steroids reduce microglia mediated neuroinflammation. In this study, the progesterone's effects on tumor necrosis factor alpha (TNF-α, iNOS, and COX-2 expression were investigated in lipopolysaccharide (LPS-stimulated BV-2 microglia. Further, investigation included nuclear factor kappa B (NF-κB and mitogen activated protein kinase (MAPK pathways. LPS (30 ng/ml upregulated TNF-α, iNOS, and COX-2 protein expression in BV-2 cells. Progesterone pretreatment attenuated LPS-stimulated TNF-α, iNOS, and COX-2 expression in a dose-dependent fashion. Progesterone suppressed LPS-induced NF-κB activation by decreasing inhibitory κBα and NF-κB p65 phosphorylation and p65 nuclear translocation. Progesterone decreased LPS-mediated phosphorylation of p38, c-Jun N-terminal kinase and extracellular regulated kinase MAPKs. These progesterone effects were inhibited by its antagonist mifepristone. In conclusion, progesterone exhibits pleiotropic anti-inflammatory effects in LPS-stimulated BV-2 microglia by down-regulating proinflammatory mediators corresponding to suppression of NF-κB and MAPK activation. This suggests progesterone may be used as a potential neurotherapeutic to treat inflammatory components of acute brain injury.

    The primary objective of this study was to determine the percentage of women with a documented plan for postpartum intrauterine device (IUD) insertion who had a device inserted within 8 weeks of delivery. The secondary objective was to determine factors associated with successful initiation of postpartum IUDs as planned. We conducted a retrospective chart review of women who had at least one prenatal visit and delivered a viable pregnancy at our academic medical center. Methods of planned and established postpartum contraceptive methods were recorded, as well as demographic information and documented reasons for failure to initiate planned intrauterine contraception. A total of 110 women planned postpartum IUD placement. Of these women, 84 (76%) presented for at least one postpartum appointment. Only 22.6% (95% confidence interval 13.7-31.5) of those presenting for postpartum follow-up underwent IUD placement within 8 weeks of delivery. Women planning postpartum IUD insertion were just as likely as women with no planned postpartum contraceptive method to fail to establish contraception within 8 weeks (P = 0.55). Failure to establish planned postpartum intrauterine contraception occurs frequently, even in a setting with a high rate of postpartum follow-up.

    Accurate postpartum depression screening measures are needed to identify mothers with depressive symptoms both in the postpartum period and beyond. Because it had not been tested beyond the immediate postpartum period, the reliability and validity of the Postpartum Depression Screening Scale (PDSS) and its sensitivity, specificity, and predictive value for diagnoses of major depressive disorder (MDD) were assessed in a diverse community sample of 238 mothers of 4- to 15-month-old infants. Mothers (N = 238; M age = 30.2, SD = 5.3) attended a lab session and completed the PDSS, the Beck Depression Inventory-II (BDI-II), and a structured clinical interview (SCID) to diagnose MDD. The reliability, validity, specificity, sensitivity, and predictive value of the PDSS to identify maternal depression were assessed. Confirmatory factor analysis supported the construct validity of five but not seven content subscales. The PDSS total and subscale scores demonstrated acceptable to high reliability (α = 0.68-0.95). Discriminant function analysis showed the scale correctly provided diagnostic classification at a rate higher than chance alone. Sensitivity and specificity for major depressive disorder (MDD) diagnosis were good and comparable to those of the BDI-II. Even in mothers who were somewhat more diverse and had older infants than those in the original normative study, the PDSS appears to be a psychometrically sound screener for identifying depressed mothers in the 15 months after childbirth. © 2018 Wiley Periodicals, Inc.

  20. Best Practices in Management of Postpartum Pain.

    Science.gov (United States)

    Fahey, Jenifer O

    Pain has been documented as a major concern for women in the postpartum period. Management of postpartum pain, however, is a relatively neglected area of clinical research. As a result, evidence to support interventions to alleviate the discomforts associated with childbirth is sparse. This paucity of research on postpartum pain management is particularly surprising given that in the United States alone nearly 4 million women give birth each year. Inadequate pain relief in the hours to months following childbirth can interfere with maternal-newborn bonding and feeding and, by impeding mobility, can increase the risk of postpartum complications. In addition, pain that is not adequately managed may increase the risk of chronic pain that lasts beyond the postpartum period. In this article, the more common causes of pain following childbirth are reviewed and recommendations for pain management based on available evidence are outlined. Considerations for pain management in lactating women and for hospital discharge are discussed.

    Full Text Available The age at which women experience their first pregnancy has increased throughout the decades. Pregnancy has an important influence on maternal short- and long-term cardiovascular outcomes. Pregnancy at an advanced maternal age increases maternal risk of gestational diabetes, preeclampsia, placenta previa and caesarian delivery; complications which predict worsened cardiovascular health in later years. Aging also independently increases the risk of cardiovascular disease; therefore, combined risk in women of advanced maternal age may lead to detrimental cardiovascular outcomes later in life. We hypothesized that pregnancy at an advanced maternal age would lead to postpartum vascular dysfunction. We used a reproductively aged rat model to investigate vascular function in never pregnant (virgin, previously pregnant (postpartum and previously mated but never delivered (nulliparous rats at approximately 13.5 months of age (3 months postpartum or equivalent. Nulliparous rats, in which pregnancy was spontaneously lost, demonstrated significantly reduced aortic relaxation responses (methylcholine [MCh] Emax: 54.2 ± 12.6% vs. virgin and postpartum rats (MCh Emax: 84.8 ± 3.5% and 84.7 ± 3.2% respectively; suggesting pregnancy loss causes a worsened vascular pathology. Oxidized LDL reduced relaxation to MCh in aorta from virgin and postpartum, but not nulliparous rats, with an increased contribution of the LOX-1 receptor in the postpartum group. Further, in mesenteric arteries from postpartum rats, endothelium-derived hyperpolarization (EDH-mediated vasodilation was reduced and a constrictive prostaglandin effect was apparent. In conclusion, aged postpartum rats exhibited vascular dysfunction, while rats which had pregnancy loss demonstrated a distinct vascular pathology. These data demonstrate mechanisms which may lead to worsened outcomes at an advanced maternal age; including early pregnancy loss and later life cardiovascular dysfunction.

    There is a large body of literature which assessed the incidence and risk factors of eclampsia, but little was done in assessing the association of clinical features and biological markers with prepartum and postpartum eclampsia. A total of 361 eclamptic women admitted to three teaching hospitals between 2008 and 2013 were included in this analysis. A comparative analysis was done for several clinical and biological variables to assess their association with prepartum and postpartum eclampsia. The overall incidence of eclampsia was 1.2% (prepartum 71% and postpartum 29%). The majority of women with prepartum eclampsia were young, primigravida, more hypertensive, symptomatic and proteinuric. Conversely, the majorities of the women with post-partum eclampsia were adult, multiparous, carrying pregnancy to term, anemic, thrombocytopenic, and with hepatic dysfunction. The commonest severity symptom (headache) was less common in postpartum eclamptic women. The incidence of eclampsia was among the highest in the world. And, the analysis has shown that the clinical and biochemical spectrum of prepartum and postpartum eclampsia were apparently different. The majority of the women who developed postpartum eclampsia were multiparous and adult. Derangement of biomarkers was also more common in women with postpartum eclampsia.

    Women with gestational diabetes mellitus (GDM) are at an increased risk for developing metabolic syndrome, type 2 diabetes mellitus (T2DM), and cardiovascular disease. In this review, we will discuss postpartum cardiovascular and diabetes risk in women with a history of GDM and different ways to improve postpartum screening. This review involves a comprehensive literature review on gestational diabetes and postpartum risk for cardiovascular disease and diabetes mellitus as well as post-partum screening methods. Cardiovascular risk post-partum is potentiated by increased inflammatory markers leading to worsening atherosclerosis and cardiovascular events downstream. Decreased insulin sensitivity and β cell compensation, recurrent GDM, maternal factors such as pre and post-partum weight gain and lactation may contribute to T2DM risk. Postpartum glucose testing is essential in screening women as hyperglycemia in pregnancy has long term effects on both cardiovascular disease and diabetes risk on the mother. Long and short term improvement to post-partum glucose testing is essential to decreasing cardiometabolic and diabetes risk in women with gestational diabetes mellitus.

    Progesterone plays critical roles in maintaining a successful pregnancy at the early embryonic stage. Human chorionic gonadotropin (hCG) rapidly induces amphiregulin (AREG) expression. However, it remains unknown whether AREG mediates hCG-induced progesterone production. Thus, the objective of this study was to investigate the role of AREG in hCG-induced progesterone production and the underlying molecular mechanism in human granulosa cells; primary cells were used as the experimental model. We demonstrated that the inhibition of EGFR and the knockdown of AREG abolished hCG-induced steroidogenic acute regulatory protein (StAR) expression and progesterone production. Importantly, follicular fluid AREG levels were positively correlated with progesterone levels in the follicular fluid and serum. Treatment with AREG increased StAR expression and progesterone production, and these stimulatory effects were abolished by EGFR inhibition. Moreover, activation of ERK1/2, but not PI3K/Akt, signaling was required for the AREG-induced up-regulation of StAR expression and progesterone production. Our results demonstrate that AREG mediates hCG-induced StAR expression and progesterone production in human granulosa cells, providing novel evidence for the role of AREG in the regulation of steroidogenesis.

    Breast cancer cell proliferation is promoted by a variety of mitogenic signals. Classically estrogen is considered as most predominant mitogenic signal in hormone-dependent breast cancer and progesterone is primarily considered to have protective effect. However, it is suggested that some progesterone metabolite may promote breast cancer and progesterone metabolites like 5α-pregnane and 4-pregnene could serve as regulators of estrogen-responsiveness of breast cancer cells. Here, we estimated the potential of alternate targeting of breast cancer via progesterone signalling. l-Proline derived novel 14-azasteroid compounds were screened against MCF-7 and MDA-MB-231 cell lines using MTT assay. In silico studies, cell cycle, Annexin-V-FITC/PI, JC-1 mitochondrial assay, ROS analysis were performed to analyse the impact of hit compound 3b on breast cancer cells. Further, we analysed the impact of hit 3b on the progesterone, its metabolites and enzymes responsible for the conversion of progesterone and its metabolites using ELISA. Data suggests that compound 3b binds and down regulates of 5α-reductase by specifically inhibiting production of progesterone metabolites that are capable of promoting breast cancer proliferation, epithelial mesenchymal transition and migration. This study establishes the proof of concept and generation of new leads for additional targeting of breast cancer. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Nearly 64% of new mothers are affected by fatigue during the postpartum period, making it the most common problem that a woman faces as she adapts to motherhood. Postpartum fatigue can lead to serious negative effects on the mother's health and the newborn's development and interfere with mother-infant interaction. The aim of this meta-analysis was to identify predictive factors of postpartum fatigue and to document the magnitude of their effects using effect sizes. We used two search engines, PubMed and Google Scholar, to identify studies that met three inclusion criteria: (a) the article was written in English, (b) the article studied the predictive factors of postpartum fatigue, and (c) the article included information about the validity and reliability of the instruments used in the research. Nine articles met these inclusion criteria. The direction and strength of correlation coefficients between predictive factors and postpartum fatigue were examined across the studies to determine their effect sizes. Measurement of predictor variables occurred from 3days to 6months postpartum. Correlations reported between predictive factors and postpartum fatigue were as follows: small effect size (r range =0.10 to 0.29) for education level, age, postpartum hemorrhage, infection, and child care difficulties; medium effect size (r range =0.30 to 0.49) for physiological illness, low ferritin level, low hemoglobin level, sleeping problems, stress and anxiety, and breastfeeding problems; and large effect size (r range =0.50+) for depression. Postpartum fatigue is a common condition that can lead to serious health problems for a new mother and her newborn. Therefore, increased knowledge concerning factors that influence the onset of postpartum fatigue is needed for early identification of new mothers who may be at risk. Appropriate treatments, interventions, information, and support can then be initiated to prevent or minimize the postpartum fatigue. Copyright © 2017 Elsevier

    Steroid hormones are well-recognized suppressors of the inflammatory response, however, their cell- and tissue-specific effects in the regulation of inflammation are far less understood, particularly for the sex-related steroids. To determine the contribution of progesterone in the endothelium, we have characterized and validated an in vitro culture system in which human umbilical vein endothelial cells constitutively express human progesterone receptor (PR).

    Full Text Available Abstract Ovarian carcinoma (OCa continues to be the leading cause of death due to gynecologic malignancies and the vast majority of OCa is derived from the ovarian surface epithelium (OSE and its cystic derivatives. Epidemiological evidence strongly suggests that steroid hormones, primarily estrogens and progesterone, are implicated in ovarian carcinogenesis. However, it has proved difficult to fully understand their mechanisms of action on the tumorigenic process. New convincing data have indicated that estrogens favor neoplastic transformation of the OSE while progesterone offers protection against OCa development. Specifically, estrogens, particularly those present in ovulatory follicles, are both genotoxic and mitogenic to OSE cells. In contrast, pregnancy-equivalent levels progesterone are highly effective as apoptosis inducers for OSE and OCa cells. In this regard, high-dose progestin may exert an exfoliation effect and rid an aged OSE of pre-malignant cells. A limited number of clinical studies has demonstrated efficacies of antiestrogens, aromatase inhibitors, and progestins alone or in combination with chemotherapeutic drugs in the treatment of OCa. As a result of increased life expectancy in most countries, the number of women taking hormone replacement therapies (HRT continues to grow. Thus, knowledge of the mechanism of action of steroid hormones on the OSE and OCa is of paramount significance to HRT risk assessment and to the development of novel therapies for the prevention and treatment of OCa.

    Full Text Available Abstract Background Realizing the importance of regular physical activity, particularly in the prevention of chronic diseases and unhealthy weight gain, it is important to study how physical activity changes during and after pregnancy using prospective study designs. The aim of this study was to describe the mode, duration, intensity, and changes in physical activity during pregnancy through one year postpartum among a cohort of women. Methods This study was part of the third Pregnancy, Infection and Nutrition Postpartum Study at the University of North Carolina Hospitals. A cohort of 471 women was followed at 17-22 and 27-30 weeks' gestation and at 3 and 12 months postpartum. The participants reported the mode, frequency, duration, and intensity of all physical activities that increased their breathing and heart rate in the past week. Results Overall physical activity for the cohort decreased from 17-22 weeks to 27-30 weeks of gestation, but rebounded up at 3 months postpartum and remained stable at 12 months postpartum. The mean MET h/wk values for each time point were 24.7 (standard deviation, SD 26.8, 19.1 (SD 18.9, 25.7 (SD 29.3, and 26.7 (SD 31.5. In postpartum, women reported more care-giving and recreational activity and less indoor household activity, as compared to their activity level during pregnancy. Conclusion For health benefits and weight management, health care professionals are encouraged to provide pregnant and postpartum women with information on recommendations of physical activity, particularly regarding the minimum duration and intensity level.

    We determined the relationships among ketosis, serum metabolites, body condition, and reproductive disorders and performance in dairy cows. Blood samples from 213 dairy cows were collected at 4 and 2 weeks prepartum, just after calving, and at 1, 2, 4, 6, and 8 weeks postpartum to measure serum β-hydroxybutyrate, nonesterified fatty acids (NEFAs), glucose, total cholesterol, urea nitrogen, aspartate aminotransferase, γ-glutamyltransferase, and progesterone concentrations. Cows were grouped on the basis of the β-hydroxybutyrate concentration at 1 and/or 2 weeks postpartum into two groups: the ketotic group (≥1200 μmol/L, n = 59) and the nonketotic group (50% pus), and subclinical endometritis was diagnosed by evaluation of uterine cytology (>18% neutrophils) at 4 weeks postpartum. Ovarian cysts were diagnosed by ultrasonography, and resumption of postpartum cyclicity was evaluated by progesterone concentrations (≥1 ng/mL) at 4, 6, and 8 weeks postpartum. In the ketotic group, NEFA levels were higher (P ≤ 0.0005), whereas glucose (P ketosis, increased reproductive disorders, and decreased reproductive performance in dairy cows.

    2016-01-01

    Summary Background Maternal depression in the postpartum period confers substantial morbidity and mortality, but the definition of postpartum depression remains controversial. We investigated the heterogeneity of symptoms with the aim of identifying clinical subtypes of postpartum depression. Methods Data were aggregated from the international perinatal psychiatry consortium Postpartum Depression: Action Towards Causes and Treatment, which represents 19 institutions in seven countries. 17 912 unique subject records with phenotypic data were submitted. We applied latent class analyses in a two-tiered approach to assess the validity of empirically defined subtypes of postpartum depression. Tier one assessed heterogeneity in women with complete data on the Edinburgh postnatal depression scale (EPDS) and tier two in those with postpartum depression case status. Findings 6556 individuals were assessed in tier one and 4245 in tier two. A final model with three latent classes was optimum for both tiers. The most striking characteristics associated with postpartum depression were severity, timing of onset, comorbid anxiety, and suicidal ideation. Women in class 1 had the least severe symptoms (mean EPDS score 10·5), followed by those in class 2 (mean EPDS score 14·8) and those in class 3 (mean EPDS score 20·1). The most severe symptoms of postpartum depression were significantly associated with poor mood (mean EPDS score 20·1), increased anxiety, onset of symptoms during pregnancy, obstetric complications, and suicidal ideation. In class 2, most women (62%) reported symptom onset within 4 weeks postpartum and had more pregnancy complications than in other two classes (69% vs 67% in class 1 and 29% in class 3). Interpretation PPD seems to have several distinct phenotypes. Further assessment of PPD heterogeneity to identify more precise phenotypes will be important for future biological and genetic investigations.

    2007-01-01

    Study objectives: Evaluate the prevalence and phenomenology of dream-associated behaviors affecting pregnant and postpartum mothers. Episodes consist of anxious dreams and nightmares about the new infant that are accompanied by complex behaviors (motor activity, speaking, expressing emotion). Design: Three-group design (postpartum, pregnant, null gravida), self-report, and repeated measures. Setting: Pregnancy and postpartum groups: completion of questionnaires in hospital room within 48 hours of giving birth and home telephone interviews; null gravida group: completion of questionnaires and interview in person or by telephone. Participants: Two hundred seventy-three women in 3 groups: postpartum: n = 202 (mean age = 29.7 ± 4.94 years; 95 primiparas, 107 multiparas); pregnant: n = 50 (mean age = 31.1 ± 5.44 years); null gravida: n = 21 (mean age = 28.5 ± 6.34 years). Interventions: Subjects completed questionnaires about pregnancy and birth factors, personality, and sleep and participated in interviews concerning the prevalence of recent infant dreams and nightmares, associated behaviors, anxiety, depression, and other psychopathologic factors. Measurements and Results: Most women in all groups recalled dreams (88%-91%). Postpartum and pregnant women recalled infant dreams and nightmares with equal prevalence, but more postpartum women reported they contained anxiety (75%) and the infant in peril (73%) than did pregnant women (59%, P dream-associated behaviors (P dream anxiety and, among postpartum women, post-awakening anxiety (41%), confusion (51%), and a need to check on the infant (60%). Primiparas and multiparas differed in dream and nightmare recall but not in prevalence of dream-associated behaviors. Conclusion: The prevalent occurrence of pregnancy and postpartum infant dreams and associated behaviors may reflect the pervasive emotional influence of maternal concerns or changes instigated by severe sleep disruption, rapid eye movement sleep deprivation

    The cow milk was collected with filter paper treated with ethanol during eastrus-day (0 day) and 22th and 24th day after mating. Then it was dried and stored in room temprature until analysis for progesterone by means of radioimmunoassay. The sensitivity is 13.62 pg/bule (n = 4), the coefficients of variation within a group and between groups are 8.8% (n = 10) and 16.65% (n = 8) respectively, and the recovery is 91.23% (n = 4). The average progesterone level for 22th and 24th day in the pregnant cows (6.28 +- 1.28 ng/ml) was much higher than that in the non-pregnant cow (2.00 +- 1.18 ng/ml), the difference being significant (P < 0.001). The judgement based on progesterone level (5 pregnant and 5 non-pregnant cows) faily agreed with the clinical diagnosis.

    There is no satisfactory therapeutic intervention for neonatal hypoxic-ischemic (HI) encephalopathy. Progesterone is known to be effective in treating traumatic brain injury in adult animals but its effects in neonatal brains have not been reported. Brain injuries were induced by a unilateral common carotid artery ligation plus hypoxia exposure. Progesterone was administered immediately after hypoxia and daily for 5 days at 8 mg/kg, followed by a tapered dose for two days. At six weeks post-injury, lesion size and inflammatory factors were evaluated. Progesterone-treated, HI-injured male animals, but not females, showed significant long-term tissue protection compared to vehicle, suggesting an important sex difference in neuroprotection. Progesterone-treated, HI-injured male rats had fewer activated microglia in the cortex and hippocampus compared to controls. The rats were tested for neurological reflexes, motor asymmetry, and cognitive performance at multiple time points. The injured animals exhibited few detectable motor deficits, suggesting a high level of age- and injury-related neuroplasticity. There were substantial sex differences on several behavioral tests, indicating that immature males and females should be analyzed separately. Progesterone-treated animals showed modest beneficial effects in both sexes compared to vehicle-treated injured animals. Sham animals given progesterone did not behave differently from vehicle-treated sham animals on any measures. Copyright © 2015 Elsevier B.V. All rights reserved.

    Full Text Available Background: Epulis Fissuratum (Epulis Fissuratum (EF or Denture Epulis or inflammatory fibrous hyperplasia is a common hyperplastic tumor-like lesion with reactive nature, related to loose and ill-fitting, full or partial removable dentures and it is more common in women than men. For this reason, hormonal influences may also play role in its creation. The effect of steroid hormones especially sex hormones (Estrogen and progesterone on oral mucosa is identified in some studies. In the present study, the distribution pattern and presence of estrogen and progesterone receptors in epithelial, stromal, endothelial and inflammatory cells in Epulis Fissuratum was investigated. Materials and Methods: This cross-sectional study was carried out on 30 samples of paraffin blocks with Epulis Fissuratum diagnosis and 30 samples of normal mucosal tissues as a control group who have had surgery as a margin beside the above lesions and had been obtained from the oral and maxillofacial pathology departement of Babol Dental School since 2003 up to 2010. Intensity of staining and immunoreactivity were evaluated using subjective index and considering the positive control group (breast carcinoma.Results: Epithelial, stromal, endothelial and inflammatory cells didn’t show reaction with monoclonal antibodies against estrogen and progesterone in none of the samples. Conclusion: It seems that the hypothesis of the existence of estrogen and progesterone receptors in epulis fissuratum and normal oral mucosa is ruled out. The possibility of direct effect of estrogen and progesterone in occurring of epulis fissuratum is rejected.

    Full Text Available Abstract Background Maternal depression during pregnancy has been studied less than depression in postpartum period. The aims of this study were to find out the prevalence of prepartum and postpartum depression and the risk factors associated in a cohort of Afro-Jamaican pregnant women in Jamaica. Methods The Zung self-rating depression scale instrument was administered to 73 healthy pregnant women at 28 weeks gestation and at 6 weeks postpartum for quantitative measurement of depression. Blood samples were collected at 8, 28, 35 weeks gestation and at day 1 and 6 weeks postpartum to study the thyroid status. Results Study demonstrated depression prevalence rates of 56% and 34% during prepartum and postpartum period, respectively. 94% women suffering depression in both periods were single. There were significant variations in both FT3 and TT4 concentrations which increased from week 8 to week 28 prepartum (p th week (p 3, TT4 and TSH there were no significant between group differences in concentrations. The major determinants of postpartum depression were moderate and severe prepartum depression and change in TT4 hormone concentrations. Conclusion High prevalence of depression was found during pre- and postpartum periods. Single mothers, prepartum depression and changes in TT4 were factors found to be significantly associated with postpartum depression.

    Premature luteinization is a possible cause of infertility in women. It is currently unknown whether environmental chemicals can induce changes associated with premature luteinization. Using rat granulosa cells (GC) in vitro, we demonstrated that exposure to atrazine (ATR), a widely used herbicide, causes GC phenotype that resembles that of human premature luteinization. At the end of the 48-h stimulation with FSH, ATR-exposed GC showed (1) higher levels of progesterone, (2) overexpression of luteal markers (Star and Cyp11a1), and (3) an increase in progesterone:estradiol ratio above 1. Mechanistic experiments were conducted to understand the signaling events engaged by ATR that lead to this phenotype. Western blot analysis revealed prolonged phosphorylation of protein kinase B (AKT) and cAMP response element-binding protein (CREB) in ATR- and FSH-exposed GC. An increased level of ERK1/2-dependent transcriptional factor CCATT/enhancer-binding protein beta (CEBPB) was observed after 4 h of ATR exposure. Inhibitors of PI3K (wortmannin) and MEK (U0126) prevented ATR-induced rise in progesterone level and expression of luteal markers in FSH-stimulated GC. Atrazine intensified AKT and CEBPB signaling and caused Star overexpression in forskolin-stimulated GC but not in epidermal growth factor (EGF)-stimulated GC. In the presence of rolipram, a specific inhibitor of phosphodiesterase 4 (PDE4), ATR was not able to further elevate AKT phosphorylation, CEBPB protein level, and Star mRNA in FSH-stimulated GC, suggesting that ATR inhibits PDE4. Overall, this study showed that ATR acts as a FSH sensitizer leading to enhanced cAMP, AKT, and CEBPB signaling and progesterone biosynthesis, which promotes premature luteinization phenotype in GC. © 2014 by the Society for the Study of Reproduction, Inc.

  18. Role of sex steroids in progesterone and corticosterone response to acute restraint stress in rats: sex differences.

    Adrenal progesterone secretion increases along with corticosterone in response to stress in male and female rats to modulate some stress responses. Here we investigated the role of sex steroids in sex differences in the progesterone response to 60 min of restraint stress in adult male and female rats. Comparisons between males and females in the progesterone response were evaluated in parallel with corticosterone responses. From day 5 to 7 after gonadectomy, female and male rats were treated with estradiol or testosterone, respectively (OVX-E and ORCH-T groups), or oil (OVX and ORCH groups). Female rats in proestrus, intact and 7 d adrenalectomized (ADX) male rats were also studied. At 10:00 h, blood samples were withdrawn via an implanted jugular cannula before (-5 min), during (15, 30, 45, 60 min) and after (90 and 120 min) restraint stress to measure plasma progesterone and corticosterone concentrations by radioimmunoassay. Intact male and proestrus female rats exhibited similar progesterone responses to stress. Gonadectomy did not alter the amount of progesterone secreted during stress in female rats but decreased secretion in male rats. Unlike corticosterone, the progesterone response to stress in females was not influenced by estradiol. In males, testosterone replacement attenuated the progesterone and corticosterone responses to stress. Basal secretion of progesterone among intact, ORCH and ADX males was similar, but ADX-stressed rats secreted little progesterone. Hence, the gonads differently modulate adrenal progesterone and corticosterone responses to stress in female and male rats. The ovaries enhance corticosterone but not progesterone secretion, while the testes stimulate progesterone but not corticosterone secretion.

    Milk for progesterone determination was taken from cows picked out for insemination, cows following insemination and cows with reproduction disorders. The samples were taken in test tubes containing potassium dichromate. Progesterone was determined by RIA of skimmed milk and the results were transmitted to the DISKOT system in the data processing centre. The use of the DISKOT system output and the monitoring of progesterone in milk by the RIA laboratory improved reproduction indexes of the herd under study. (E.J.). 2 tabs

    2014-01-01

    Thyroiditis encompasses a group of disorders characterized by thyroid inflammation. Though clinically indistinguishable from silent thyroiditis, postpartum thyroiditis occurs in women within 12 months after delivery. Recurrent postpartum thyroiditis in subsequent pregnancies is common, but recurrent silent thyroiditis is rare. We reported a case of patient with recurrent episodes of thyroiditis, unrelated to pregnancy, after an episode of postpartum thyroiditis. It is of interest that postpartum thyroiditis and silent thyroiditis could occur closely to each other; however, the link between these disorders is not well established. This report is to remind physicians of the possibility of recurrent silent thyroiditis in women with a history of postpartum thyroiditis. PMID:24987536

    Postpartum anxiety disorders are common and may have significant consequences for mothers and their children. This review examines the literature on women's experiences with postpartum generalized anxiety disorder (GAD), postpartum panic disorder (PD), obsessive compulsive disorder (OCD), and posttraumatic stress disorder (PTSD). MEDLINE (Ovid), CINAHL, PsycINFO, and reference lists were searched. Qualitative and quantitative studies assessing women's experiences with GAD, postpartum PD, OCD, and PTSD were included. Narrative approach to literature synthesis was used. Fourteen studies (among 44 articles) met the criteria for review to identify descriptions of women's cognitive, affective, and somatic experiences related to postpartum anxiety disorders. Loss, frustration, and guilt, accompanied by physical symptoms of tension, were some of the experiences identified across studies. Most women suffered from more than one anxiety disorder, in addition to postpartum depression. To date, research has focused on prevalence rates of postpartum anxiety disorders, and evidence about clinical and subclinical symptoms of postpartum anxiety disorders and outcomes on mother and child is lacking. Postpartum anxiety disorders may have negative effects on parenting and child development; however, the nature of the underlying mechanisms is unclear. More robust longitudinal studies are needed to examine the impact of postpartum GAD, PD, OCD, and PTSD symptoms on the mother and the mother-child relationship to develop targets for therapeutic preventative interventions.

    The postpartum period is under-researched in low and middle income countries. The scarce literature reveals heavy burden of ill health experienced in that period and under utilisation of health services. Understanding the postpartum morbidity burden and identifying the care-seeking behaviours is essential to improve service delivery. This paper examines reported postpartum morbidity, care seeking behaviour and whether postpartum morbidity is associated with method of birth. A cross sectional study of women delivering in 18 private hospitals from two regions in Lebanon was undertaken. Women in their second or third trimester of pregnancy, visiting private obstetric clinics affiliated with participating hospitals were interviewed for baseline information. Reported postpartum morbidity was assessed in an interview conducted at women's homes from 40 days up to six months postpartum. Of the 269 women recruited, physical postpartum health problems were reported by 93.6% and psychological health problems by 84.4% of women, with more health problems being reported beyond two months postpartum. Women were less likely to seek professional care for psychological health problems. Reporting postpartum health problems was not associated with method of birth. A heavy burden of postpartum morbidity is experienced by women with gaps in utilisation of relevant health services. Efforts should be directed towards the organisation and delivery of comprehensive maternity care services. Copyright © 2013 Australian College of Midwives. Published by Elsevier Ltd.

    Steroid production by the ovary is primarily stimulated by gonadotropins but can also be affected by biological cues that provide information about energy status and environmental stress. To further understand which metabolic cues the ovary can respond to, we exposed gonadotropin-stimulated mouse ovaries in vitro to glucose metabolism inhibitors and measured steroid accumulation in media. Gonadotropin-stimulated ovaries exposed to 2-deoxy-d-glucose increased progesterone production and steroidogenic acute regulatory protein mRNA levels. However, oocytes and granulosa cells in antral follicles do not independently mediate this response because targeted treatment of these cell types with a different inhibitor of glucose metabolism (bromopyruvic acid) did not affect progesterone production. Elevated progesterone production is consistent with the homeostatic role of progesterone in glucose regulation in mammals. It also may regulate follicle growth and/or atresia within the ovary. These results suggest that ovaries can regulate glucose homeostasis in addition to their primary role in reproductive activity. © 2017. Published by The Company of Biologists Ltd.

    The postpartum period is characterized by complex hormonal changes, but human imaging studies in the postpartum period have thus far predominantly focused on the neural correlates of maternal behavior or postpartum depression, whereas longitudinal studies on neural correlates of cognitive function across the postpartum period in healthy women are lacking. The aim of this study was to longitudinally examine response inhibition, as a measure of executive function, during the postpartum period and its neural correlates in healthy postpartum women and non-postpartum controls. Thirteen healthy postpartum women underwent event-related functional magnetic resonance imaging while performing a Go/NoGo task. The first assessment was made within 48 h of delivery, and the second at 4-7 weeks postpartum. In addition, 13 healthy women examined twice during the menstrual cycle were included as non-postpartum controls. In postpartum women region of interest analyses revealed task-related decreased activations in the right inferior frontal gyrus, right anterior cingulate, and bilateral precentral gyri at the late postpartum assessment. Generally, postpartum women displayed lower activity during response inhibition in the bilateral inferior frontal gyri and precentral gyri compared to non-postpartum controls. No differences in performance on the Go/NoGo task were found between time-points or between groups. In conclusion, this study has discovered that brain activity in prefrontal areas during a response inhibition task decreases throughout the course of the first postpartum weeks and is lower than in non-postpartum controls. Further studies on the normal adaptive brain activity changes that occur during the postpartum period are warranted. Copyright © 2012 Elsevier B.V. All rights reserved.

  6. Transition Metal Chelator Induces Progesterone Production in Mouse Cumulus-Oocyte Complexes and Corpora Lutea.

    Progesterone production is upregulated in granulosa cells (cumulus and mural) after the LH surge, but the intra-follicular mechanisms regulating this transition are not completely known. Recent findings show that the transition metal chelator, N,N,N',N'-tetrakis-(2-pyridylmethyl)-ethylenediamine (TPEN), impairs ovarian function. In this study, we provide evidence that chelating transition metals, including zinc, enhances progesterone production. The findings show that TPEN (transition metal chelator) increases abundance of Cyp11a1 and Star messenger RNA (mRNA) between 8- and 20-fold and progesterone production more than 3-fold in cultured cumulus-oocyte complexes (COC). Feeding a zinc-deficient diet for 10 days, but not 3 days, increased Star, Hsd3b, and prostaglandin F2 alpha receptor (Ptgfr) mRNA ~2.5-fold, suggesting that the effect of TPEN is through modulation of zinc availability. Progesterone from cumulus cells promotes oocyte developmental potential. Blocking progesterone production with epostane during maturation reduced subsequent blastocyst formation from 89 % in control to 18 % in epostane-treated complexes, but supplementation with progesterone restored blastocyst developmental potential to 94 %. Feeding a zinc-deficient diet for 5 days before ovulation did not affect the number of CL, STAR protein, or serum progesterone. However, incubating luteal tissue with TPEN increased abundance of Star, Hsd3b, and Ptgfr mRNA 2-3-fold and increased progesterone production 3-fold. TPEN is known to abolish SMAD2/3 signaling in cumulus cells. However, treatment of COC with the SMAD2/3 phosphorylation inhibitor, SB421542, did not by itself induce steroidogenic transcripts but did potentiate EGF-induced Star mRNA expression. Collectively, the results show that depletion of transition metals with TPEN acutely enhances progesterone biosynthesis in COC and luteal tissue.

    Triptolide(CAS 38748-32-2), a major active component of Tripterygium wilfordii Hook F (TWHF), is known to have multiple pharmacological activities. However, studies have also shown that triptolide is highly disrupt to the reproductive system by disrupting normal steroid hormone signaling. In the present study, we investigated the effect of triptolide (5, 10, or 20 nM for 24 h) on progesterone production by rat granulosa cells. Triptolide inhibited both basal and human chorionic gonadotropin (HCG)- and 8-bromo-cAMP-stimulated progesterone production as revealed by RIA assay. Furthermore, the HCG-evoked increase in cellular cAMP content was also inhibited by triptolide, indicating that disruption of the cAMP/PKA signaling pathway may mediate the deleterious effects of triptolide on progesterone regulation. In addition, triptolide inhibited 25-OH-cholesterol-stimulated progesterone production, suggesting that activity of the P450 side chain cleavage (P450scc) enzyme was also be inhibited by triptolide. Western blot and quantitative real-time PCR (qRT-PCR) assays further revealed that triptolide decreased mRNA and protein expression of P450scc and the steroidogenic regulatory (StAR) protein in granulosa cells. In contrast, cell viability tests using 3-(4,5-dimethyl-thiazol-2-yl)-2,5- diphenyl-tetrazolium bromide (MTT) indicated that triptolide did not cause measurable cell death at doses that suppressed steroidogenesis. The reproductive toxicity of triptolide may be caused by disruption of cAMP/PKA-mediated expression of a number of progesterone synthesis enzymes or regulatory proteins, leading to reduced progesterone synthesis and reproductive dysfunction. © Georg Thieme Verlag KG Stuttgart · New York.

    Use of progesterone, measurement to monitor artificial insemination, reproductive functions and pregnancy in tunisian and pregnancy in tunisian cattle Results saved during field application in four Tunisian farms from 924 dairy cows. A total of 2830 milk samples were collected from these cows at 3 fixed intervals to evaluate the level of Progesterone: at Artificial Insemination (AI) time (1034), 12th day (948) and at 22nd to 24th days after AI (848). Progesterone concentrations in samples done at AI moment (n=1034) revealed that 10.1% of cows was inseminated at improper moment (progesterone level higher or equal to 1nmol/l). In the second category (samples collected 12 days after AI, n=948), allowed distinguishing between two different situations: (1)- Cycling cows: progesterone concentration was higher or equal to 3nmol/l (69.4%). (2)- Non cycling cows: progesterone level was strictly lower than 3nmol/l (30.6%). The aim of progesterone assay of samples collected in the third category (22 to 24 days after AI) is to establish the Early Non Pregnancy Diagnosis (ENPD). Recorded data allow distinguishing: (1)- Non pregnant females: progesterone concentration is strictly less than 2nmol/l. The confirmation of this situation was carried out by rectal palpation. The gathered information indicated that ENPD accuracy is equal to 96.6%. (2)- Pregnant females: progesterone level is to be higher than or equal to 3.5nmol/l. The ENPD accuracy is 73.3% after confirmation using rectal palpation. (3)- Doubtful females: progesterone concentration is to be between (2 and 3.5nmol/l). Fertility and fecundity criteria were determined by using AIDA software, the analysis considered some variation factors such as cow parity, body score condition, number of services, inseminator, and milk production

    Perfluoroalkyl substances (PFASs) are a class of fluorine substituted carboxylic acid, sulfonic acid and alcohol, structurally similar to their corresponding parent compounds. Previous study demonstrated the potential endocrine disruption and reproductive toxicity of perfluorooctane sulfonic acid and perfluorooctanoic acid, two dominant PFASs in animals and humans. We explored the relationship between eleven perfluoroalkyl acids (PFAAs) with different carbon chain length and their ability to inhibit progesterone production in mouse Leydig tumor cells (mLTC-1). We found an obvious dose-response relationship between progesterone inhibition rate and PFAA exposure concentration in mLTC-1. The relative inhibition rate of progesterone by PFAAs was linearly related to the carbon chain length and molar refractivity of PFAAs. Mitochondrial membrane potential (MMP) decreased after PFAA exposure at the half-maximal inhibitory effect concentration (IC 50 ) of progesterone production in mLTC-1, while the reactive oxygen species (ROS) content increased significantly. These results imply that the inhibition effect of PFAAs on progesterone production might be due, in part, to ROS damage and the decrease in MMP in mLTC-1. Copyright © 2016.

    The purpose of this study was to examine the lactogenic response of human mammary cancer cell lines to hormones in vitro. Progesterone was found to stimulate the incorporation of 14C from [14C]acetate into triglycerides (TG) and to promote accumulation of TG with a fatty acid composition similar to that of human milk fat in T-47D cells. Lipid droplets were observed in larger numbers without concomitant accumulation of casein granules in cells incubated with progesterone, but secretion of lipid into the medium did not occur. An effect of progesterone on TG accumulation was detectable after 12 hr and was maximal at 72 hr. Increasing doses of progesterone (10(-9) to 10(-5) M) caused a progressive increase in TG accumulation. The presence of cortisol and/or prolactin did not alter TG formation nor the dose response of the cells to progesterone. The growth rate of T-47D cells was not altered by the presence of progesterone in the medium. Neither of the human mammary cancer cell lines, MCF-7 and HBL-100, nor the human fibroblast cell lines, 28 and 857, responded to progesterone. The data indicate that, while the normally lactogenic hormones do not stimulate milk product biosynthesis in the cell lines tested, progesterone specifically stimulated synthesis and accumulation of TG in the T-47D cells

    This study assessed the stability of maternal anxiety and concordance between State-Trait Anxiety Inventory (STAI) scores in the immediate postpartum period to 8 weeks postpartum. A population-based sample of 522 mothers completed the STAI at 1, 4, and 8 weeks postpartum. Sensitivity, specificity, and predictive power of the 1-week STAI in relation to identifying mothers with elevated STAI scores at 4 and 8 weeks was determined. Predictive power of the STAI was further assessed using odds ratios and receiver operator characteristic (ROC) curves. At 1 week postpartum, 22.6% of mothers scored >40 on the STAI, decreasing to 17.2% at 4 weeks and 14.8% at 8 weeks. Using the cut-off score of >40, the 1-week STAI accurately classified 84.0% mothers at 4 weeks and 83.6% at 8 weeks with or without anxiety symptomatology. The 1-week STAI was significantly correlated to the 4-week (r=0.68, p40 were 15.2 times more likely at 4 weeks (95% CI=8.9-26.1) and 14.0 times more likely at 8 weeks (95% CI=7.9-24.8) to exhibit postpartum anxiety symptomatology. Psychiatric interviews were not completed in collaboration with the STAI and specific types of anxiety disorders were not identified. A cut-off score of >40 on the STAI administered early in the postpartum period is recommended in a 2-phase identification program in order to not miss mothers with postpartum anxiety. © 2013 Elsevier B.V.

    Contraceptive education is generally considered a standard component of postpartum care, but the effectiveness is seldom examined. Two-thirds of postpartum women may have unmet needs for contraception, and many adolescents become pregnant again within a year of giving birth. Women may prefer to discuss contraception prenatally or after hospital discharge. The objective of this systematic review was to assess the effects of educational interventions for postpartum mothers about contraceptive use. We searched computerized databases for randomized controlled trials that evaluated the effectiveness of postpartum contraceptive education. The intervention must have started within 1 month after delivery. The Mantel-Haenszel odds ratio was calculated with 95% confidence interval for the dichotomous outcomes. Eight trials met the inclusion criteria. Of 4 short-term interventions, 1 did not have sufficient data and 1 was statistically underpowered. The remaining 2 showed a positive effect on contraceptive use. Of 4 multifaceted programs, 2 showed fewer pregnancies or births among adolescents in the experimental group that had enhanced services, and 1 structured home-visiting program showed more contraceptive use. The effective interventions were conducted in Australia, Nepal, Pakistan, and the United States. Postpartum education about contraception led to more contraception use and fewer unplanned pregnancies. Short-term interventions were limited by self-reported outcomes or showing no effect for many comparisons. The longer-term programs were promising and not necessarily more costly than usual care. Health care providers can determine if 1 of these interventions suits their setting and level of resources. Obstetricians & Gynecologist, Family Physicians. After completing this educational activity, the participant should be better able to assess the importance of assessing delivery methods when examining intervention quality, evaluate the evidence from randomized trials on

    Postpartum depression (PPD) is a common complication following childbirth experienced by one in every five new mothers. Although the neural basis of PPD remains unknown previous research in rats has shown that gestational stress, a risk factor for PPD, induces depressive-like behavior during the postpartum period. Moreover, the effect of gestational stress on postpartum mood is accompanied by structural modifications within the nucleus accumbens (NAc) and the medial prefrontal cortex (mPFC) – limbic regions that have been linked to PPD. Mothers diagnosed with PPD are often prescribed selective serotonin reuptake inhibitor (SSRI) antidepressant medications and yet little is known about their effects in models of PPD. Thus, here we investigated whether postpartum administration of Citalopram, an SSRI commonly used to treat PPD, would ameliorate the behavioral and morphological consequences of gestational stress. In addition, we examined the effects of gestational stress and postpartum administration of Citalopram on structural plasticity within the basolateral amygdala (BLA) which together with the mPFC and NAc forms a circuit that is sensitive to stress and is involved in mood regulation. Our results show that postpartum rats treated with Citalopram do not exhibit gestational stress-induced depressive-like behavior in the forced swim test. In addition, Citalopram was effective in reversing gestational stress-induced structural alterations in the postpartum NAc shell and mPFC. We also found that gestational stress increased spine density within the postpartum BLA, an effect which was not reversed by Citalopram treatment. Overall, these data highlight the usefulness of gestational stress as a valid and informative translational model for PPD. Furthermore, they suggest that structural alterations in the mPFC-NAc pathway may underlie stress-induced depressive-like behavior during the postpartum period and provide much needed information on how SSRIs may act in the

    To investigate whether the progesterone can promote fibronection (FN) synthesis by human bone marrow mesenchymal stem cells (MSCs) and to explore the potential underlying mechanism. The human bone marrow MSCs were cultured in a serum-free medium with progesterone for 72 hours, the MTT test was performed to observe the proliferation status and adhension ability of the treated cells. Western blot was used to detect the content of FN in MSDs with GAPDH as the internal reference, the phosphorylation of ERK1/2, as well as the FN content in MSC treated by PD98059, a specific inhibitor of ERK1/2. The progesterone at a range of certain doses not effect on the proliferation of human bone marrow MSCs. Progesterone (25 µg/L) treatment enhanced the FN expression and adherent ability of marrow MSCs. Progesterone could induce prompt phosphorylation of ERK 1/2 and its promoting effects on FN synthesis was reversed by PD98059. The progesterone can promote FN synthesis by human bone marrow MSCs via ERK 1/2 pathway, and it might be used to culture MSCs in serum-free medium.

    Granulosa cells proliferate, differentiate, and undergo apoptosis throughout follicular development. Previous studies have demonstrated that stimulation of progesterone production is accompanied by caspase-3 activation. Moreover, we previously reported that arsenic enhanced caspase-3 activity coupled with progesterone production. Inhibition of caspase-3 activity can significantly inhibit progesterone production induced by arsenic or follicle-stimulating hormone (FSH). Here, we report that serum starvation induces caspase-3 activation coupled with augmentation of progesterone production. Serum starvation also increased the levels of cytochrome P450 cholesterol side chain cleavage enzyme (P450scc) and steroidogenic acute regulatory (StAR) protein, both of which may contribute to progesterone synthesis in preovulatory granulosa cells. Inhibition of caspase-3 activity resulted in a decrease in progesterone production. Deactivation of caspase-3 activity by caspase-3 specific inhibitor also resulted in decreases in P450scc and StAR expression, which may partly contribute to the observed decrease in progesterone production. Our study demonstrates for the first time that progesterone production in preovulatory granulosa cells is required for caspase-3 activation in a serum starvation model. Inhibition of caspase-3 activity can result in decreased expression of the steroidogenic proteins P450scc and StAR. Our work provides further details on the relationship between caspase-3 activation and steroidogenesis and indicates that caspase-3 plays a critical role in progesterone production by granulosa cells.

    The childbirth constitutes a significant event in a woman's life and in the marital/ couple dyad. The changes which follow childbirth require re-organization of previous coping styles and development of new methods of adaptation, which proves difficult. The current study evaluated to what extent the development of postpartum depression symptoms in new mothers was associated with their level of satisfaction in marital relationship. The study included 100 women in their first month after delivery. The women completed questionnaires regarding postpartum depression (Postpartum Depression Screening Scale) and marital relationship quality (Marital Compatibility Questionnaire). There was a significant correlation between the level of postpartum depression and relationship quality. A greater severity of postpartum depression symptoms (sleeping/ eating disturbances, anxiety/insecurity, emotional lability, mental confusion, loss of self, guilt/ shame, suicidal thoughts) occurred in women who were less satisfied with their relationship, i.e., those who experienced a decreased level of intimacy, self-fulfillment and partner similarity, as well as a deeper sense of disillusionment. Women who declared deeper satisfaction with their relationship displayed a greater sense of mental well-being. No correlation was found between the occurrence of postpartum depression and socio-demographic factors (age, education level, place of residence) and factors associated with the subjects' childbearing history (number of children, number of pregnancies, history of miscarriage, family planning, prior diagnosis of depression, type of delivery, newborn's condition following birth, infant feeding method). Patients dissatisfied with the quality of their marital relationship experienced an increased severity of postpartum depression symptoms. Greater satisfaction with relationship quality was expressed by women in formalized relationships.

    The purpose of this study is to explore the apparent social mediation of a postpartum somatic illness, na tadoka ni vasucu, occurring among ethnic Fijian women. During their first two postpartum days, 85 consecutive newly delivered ethnic Fijian women were recruited for a prospective study on na tadoka ni vasucu at the Sigatoka District Hospital in Nadroga, Fiji. Subjects underwent translated structured interviews and responded to the Kellner Symptom Questionnaire and to visual analog scales to assess social supports and occurrence of mood symptoms or an episode of na tadoka ni vasucu in the postpartum period. Semistructured ethnographic interviews were also conducted with subjects who reported an episode of na tadoka ni vasucu. Data were collected in the initial postpartum days and again at 2 to 5 months postpartum; 82 women completed the study. Na tadoka ni vasucu is a somatic syndrome occurring in 9% (N = 7) of this sample. Both quantitative and narrative data demonstrate that this syndrome is associated with perceived inferior social supports. Despite its relatively infrequent occurrence and benign clinical course, the disorder is a subject of serious social concern within the Fijian community. Although na tadoka ni vasucu seems to be clinically trivial, because of its cultural salience it is nonetheless able to mobilize intensive social surveillance and care for the postpartum mother. The moral concern generated by this culturally marked disorder, as well as its association with perceived inferior social supports, suggest a dialectical relationship between somatic idiom and its social context.

    1 This study describes the effects of ovarian steroid hormones upon the responses to adrenoceptor agonists of isolated myometrium, separated into its longitudinal and circular layers, and of costo-uterine muscle from guinea-pigs. The preparations were field-stimulated at 100 s intervals, and the adrenoceptor agonists phenylephrine and isoprenaline produced enhancement or inhibition of the evoked contractions. 2 Isoprenaline produced propranolol-sensitive inhibitory effects in longitudinal and circular myometrium and costo-uterine muscle preparations from animals from all experimental groups: i.e. from nonsteroid-treated animals (ovariectomized and intact); intact animals treated with either oestrogen or progesterone alone; ovariectomized animals treated with oestrogen; ovariectomized and intact animals treated with progesterone following oestrogen priming; and from animals 1-4 days post-partum. Longitudinal myometrial preparations from progesterone-treated oestrogen-primed and from post-partum animals were most sensitive to this agonist. 3 Phenylephrine produced phentolamine-sensitive excitatory effects in circular myometrial and costo-uterine muscle preparations from animals from all the experimental groups. In contrast, propranolol-sensitive inhibitory responses to phenylephrine occurred in longitudinal myometrial preparations taken from animals treated with progesterone following oestrogen priming, and from post-partum animals. Longitudinal myometrium from animals from the remaining experimental groups exhibited phentolamine-sensitive excitatory responses to phenylephrine. 4 The basis for the selective effect upon the longitudinal myometrium of exposure to progesterone following a period of oestrogen priming, is discussed. The results described are consistent with the possibility that in the longitudinal layer of guinea-pig uterus exposed to progesterone following oestrogen priming there is an increase in the proportion of β-adrenoceptors in this layer.

    Airway remodeling is a vital component of chronic obstructive pulmonary disease (COPD). Despite the broad anti-inflammation effects of glucocorticoids, they exhibit relatively little therapeutic benefit in COPD, indicating the accelerating demands of new agents for COPD. We aim to explore the effect of progesterone on airway remodeling in a murine modeling of exposing to ozone and to further examine the potential effect of progesterone on glucocorticoid insensitivity. C57/BL6 mice were exposed to ozone for 12 times over 6 weeks, and were administered with progesterone alone or combined with budesonide (BUD) after each exposure until the 10th week. The peribronchial collagen deposition was measured. The protein levels of MMP8 and MMP9 in bronchoalveolar lavage fluid (BALF) and lungs were assessed. Western blot analysis was used to detect the levels of hypoxia-inducible factor-1α (HIF-1α), vascular endothelial growth factor (VEGF), a-smooth muscle actin (α-SMA), glycogen synthase kinase-3β (GSK-3β). The expression of VEGF and histone deacetylase 2 (HDAC2) in the lung were determined by Immunohistochemical analyses. We observe that progesterone attenuates the peribronchial collagen deposition, as well as the expression of MMP8, MMP9, HIF-1α, VEGF, α-SMA, and GSK-3β in BALF or lung tissues. Progesterone or BUD monotherapy has no effect on HDAC2 production. Progesterone combines with BUD induce dramatically enhanced effects. Thus, these results demonstrate novel roles of progesterone for the pathogenesis and airway remodeling in COPD. Progesterone plus BUD administration exerts more significant inhibition on airway remodeling with dose-independent. Additionally, progesterone may, to some extent, improve the glucocorticoid insensitivity. Copyright © 2018. Published by Elsevier Ltd.

    Full Text Available The binucleate trophoblast cells (CTBs of the water buffalo placenta (Bubalus bubalis were studied with emphasis on the presence of progesterone receptor. Placentomal tissues from 27 buffalos (2-10 months of pregnancy were processed and embedded in paraplast (Paraplast Embedding Media – Paraplast Plus to locate the progesterone receptors using the immunohistochemistry technique. The immunohistochemical reaction for progesterone receptor through monoclonal antibody PgR Ab2 showed staining of CTBs, caruncular epithelial and estromal cells and blood vessel estromal pericitos present in the placentome throughout the entire gestational period analyzed. These results indicate the production of progesterone with autocrine and paracrine action in the placentome growth, differentiation and functional regulation.

    Full Text Available Background: Contraception is an important intervention to reduce burden of unwanted pregnancy and promote healthy living among women. Objectives: To find out the postpartum contraceptive usage and identify the different variables which affect the postpartum contraception among the rural females of Bareilly district. Methods: The cross sectional study was carried out in randomly selected villages of Bhojipura Block of Bareilly district, Uttar Pradesh. All women who had delivered within last one year were interviewed by house to house survey to collect data regarding socio-demographic characteristics and contraceptive use by structured questionnaire. A total of 123 women participated in the study. Chi- square test was used to analyze data. Results: Only 13.8% mothers adopted postpartum contraception. Lack of knowledge (32.5% and young infant being breastfed (28.5% were the common reasons of not using any contraceptive method. Contraceptive use was higher amongst females aged less than 30 years and those belonging to middle socioeconomic class and nuclear families. The significant influence of the women’ educational status on utilization of family planning methods was observed (p<0.05. Conclusions: Low percent of postpartum contraceptive use indicates the need for improving awareness among the study population.

    Treatment with progesterone protects the male and female brain against damage after middle cerebral artery occlusion (MCAO). However, in both sexes, the brain contains significant amounts of endogenous progesterone. It is not known whether endogenously produced progesterone enhances the resistance of the brain to ischemic insult. Here, we used steroid profiling by gas chromatography-tandem mass spectrometry (GC-MS/MS) for exploring adaptive and sex-specific changes in brain levels of progesterone and its metabolites after MCAO. We show that, in the male mouse brain, progesterone is mainly metabolized via 5α-reduction leading to 5α-dihydroprogesterone (5α-DHP), also a progesterone receptor (PR) agonist ligand in neural cells, then to 3α,5α-tetrahydroprogesterone (3α,5α-THP). In the female mouse brain, levels of 5α-DHP and 3α,5α-THP are lower and levels of 20α-DHP are higher than in males. After MCAO, levels of progesterone and 5α-DHP are upregulated rapidly to pregnancy-like levels in the male but not in the female brain. To assess whether endogenous progesterone and 5α-DHP contribute to the resistance of neural cells to ischemic damage, we inactivated PR selectively in the CNS. Deletion of PR in the brain reduced its resistance to MCAO, resulting in increased infarct volumes and neurological deficits in both sexes. Importantly, endogenous PR ligands continue to protect the brain of aging mice. These results uncover the unexpected importance of endogenous progesterone and its metabolites in cerebroprotection. They also reveal that the female reproductive hormone progesterone is an endogenous cerebroprotective neurosteroid in both sexes. SIGNIFICANCE STATEMENT The brain responds to injury with protective signaling and has a remarkable capacity to protect itself. We show here that, in response to ischemic stroke, levels of progesterone and its neuroactive metabolite 5α-dihydroprogesterone are upregulated rapidly in the male mouse brain but not in the

    To evaluate the effect of cesarean section (CS) and vaginal delivery (VD) on postpartum stress urinary incontinence (SUI) and pelvic floor muscles strength and to find out the correlated obstetric factors and prevention for postpartum SUI. Totally, 788 women, who visited the antenatal clinics, delivered and had the follow-up at 6-8 weeks after delivery in Beijing Obstetrics and Gynecology Hospital in the year of 2008, were enrolled in this study and were divided into 3 groups: CS group (n = 212); normal vaginal delivery (NVD) group (n = 534) and forceps delivery (FD) group (n = 42). Women in the NVD and FD group were merged into one VD group and then divided into SUI and non-SUI group. Information of delivery mode and the correlated obstetric factors were obtained through questionnaires and medical records. Femiscan pelvic floor muscle examine system was applied to measure the pelvic floor muscle strength to understand the relationship between postpartum SUI and pelvic floor muscle strength. (1) Incidence of SUI: the overall proportion of women who complained of urinary incontinence (UI) during pregnancy was 15.4% (121/788), and it was 15.9% (85/534), 11.9% (5/42) and 14.6% (31/212) in the NVD, FD and CS group, respectively (P > 0.05). The overall incidence of postpartum SUI was 17.1% (135/788), and it was 19.1% (102/534), 26.2% (11/42) and 10.4% (22/212) in the NVD, FD and CS group, respectively, with significant difference between the NVD and FD group, and between the CS and NVD group (all P factors of postpartum SUI: among the VD group, 113 women were in the postpartum SUI group and 463 in the non-SUI group. Univariate analysis and logistic multivariate analysis showed that delivery mode, neonatal birth weight and UI during pregnancy were risk factors of postpartum SUI. CS decreased and higher neonatal birth weight and UI during pregnancy increased the risk of postpartum SUI. In the VD group, neonatal birth weight, forceps delivery and UI during pregnancy

    We describe a woman who presented with a psychiatric disorder post-partum and subsequently developed seizures and cognitive dysfunction prompting further investigation. A diagnosis of limbic encephalitis (LE) was made and antibodies to voltage-gated potassium channel complex (VGKC) detected. These antibodies are found in many non-paraneoplastic patients with LE. Although antibody-mediated conditions tend to present or relapse post-partum, VGKC-LE in the post-partum period has not been described. Case report. Clinical and imaging data were consistent with limbic encephalitis. High titres of anti-VGKC-complex antibodies confirmed the diagnosis of VGKC-LE. The similarities between the psychiatric symptomatology of VGKC-LE and post-partum psychiatric disorders raise the possibility that some instances of post-partum psychiatric conditions are manifestations of immune-mediated, non-paraneoplastic LE.

    Similar to biological mothers during the postpartum period, women who adopt children experience increased stress and life changes that may put them at risk for developing depression and anxiety. The purpose of the current study was to compare levels of depression and anxiety symptoms between postpartum and adoptive women and, among adoptive women, to examine associations between specific stressors and depressive symptoms. Data from adoptive mothers (n=147), recruited from Holt International, were compared to existing data from postpartum women (n=147). Differences in the level of depression and anxiety symptoms as measured by the Inventory of Depression and Anxiety Symptoms among postpartum and adoptive women were examined. Associations between specific stressors and depressive symptoms were examined among adoptive mothers. Postpartum and adoptive women had comparable levels of depressive symptoms, but adoptive women reported greater well-being and less anxiety than postpartum women. Stressors (e.g., sleep deprivation, history of infertility, past psychological disorder, and less marital satisfaction) were all significantly associated with depressive symptoms among adoptive women. The level of depressive symptoms was not significantly different between the two groups. In contrast, adoptive women experienced significantly fewer symptoms of anxiety and experienced greater well-being. Additionally, adoptive mothers experienced more depressive symptoms during the year following adoption when the stressors were present. Thus, women with these characteristics should be routinely screened for depression and anxiety. PMID:21725836

    Full Text Available Postpartum Depression is the most common complicationof the delivery and affects approximately 10%-15% ofwomen who had just gave birth. During a period in whichwomen believe that they should be happy, the depressivemood experienced by most women leads to feelings ofguilt, hiding the symptoms, and postpartum depressionto be overlooked. Although the incidence of serious psychiatricdisorders during pregnancy is low, it is reportedthat the incidence shows a dramatic increase during thepostpartum period and this risky period may continue upto six months, one year or even two years.As the onset of postpartum depression is insidious it caneasily be overlooked if the patient’s seeking help is notsupported, especially when the severity of postpartum depressionis mild or moderate. In these cases, postpartumdepression may persist for a long time and at last it can beso severe that hospitalization would be needed. Therefore,early diagnose is very important and primary carephysicians and other health care workers should be alert.Postpartum Depression should be diagnosed using reliabledescriptive methods in puerperant women.

    Full Text Available BACKGROUND: Every year approximately 74,000 women die of endometrial cancer, mainly due to recurrent or metastatic disease. The presence of tumor infiltrating lymphocytes (TILs as well as progesterone receptor (PR positivity has been correlated with improved prognosis. This study describes two mechanisms by which progesterone inhibits metastatic spread of endometrial cancer: by stimulating T-cell infiltration and by inhibiting epithelial-to-mesenchymal cell transition (EMT. METHODOLOGY AND PRINCIPAL FINDINGS: Paraffin sections from patients with (n = 9 or without (n = 9 progressive endometrial cancer (recurrent or metastatic disease were assessed for the presence of CD4+ (helper, CD8+ (cytotoxic and Foxp3+ (regulatory T-lymphocytes and PR expression. Progressive disease was observed to be associated with significant loss of TILs and loss of PR expression. Frozen tumor samples, used for genome-wide expression analysis, showed significant regulation of pathways involved in immunesurveillance, EMT and metastasis. For a number of genes, such as CXCL14, DKK1, DKK4, PEG10 and WIF1, quantitive RT-PCR was performed to verify up- or downregulation in progressive disease. To corroborate the role of progesterone in regulating invasion, Ishikawa (IK endometrial cancer cell lines stably transfected with PRA (IKPRA, PRB (IKPRB and PRA+PRB (IKPRAB were cultured in presence/absence of progesterone (MPA and used for genome-wide expression analysis, Boyden- and wound healing migration assays, and IHC for known EMT markers. IKPRB and IKPRAB cell lines showed MPA induced inhibition of migration and loss of the mesenchymal marker vimentin at the invasive front of the wound healing assay. Furthermore, pathway analysis of significantly MPA regulated genes showed significant down regulation of important pathways involved in EMT, immunesuppression and metastasis: such as IL6-, TGF-β and Wnt/β-catenin signaling. CONCLUSION: Intact progesterone signaling in non

    The anti progesterone antibody was obtained by injection of local sudanese sheep (bevies arias) intramuscularly and subcutaneously using 11-a-hydroxy progesterone conjugated with bovine serum albumin and emulsified in friend's adjuvant. The blood samples collected one week after the 3 rd injection was tested for anti-progesterone antibodies. Different dilutions of antisera in Pbs containing 0.0.1 % BSA and 0.1 % Na N 3 (Ph 7.4) were made. Using these dilutions, polystyrene balls of 6.4 mm diameter were coated with a coating volume of 500 μ1/bead.The antibody dilution of 1/200000 was selected and used for assembling a kit to measure progesterone level in serum. Optimization of the assay condition resulted in the following recipes: Fifty μ1 of standard or Qc (Low, normal and high) from Bio Rad for 2 hours. The reaction medium aspirated, washed twice and read for 100 seconds in gamma counter. Assay validation tests including Linearity, recovery, reproducibility and comparability were done. In regards to linearity, the measured concentrations of progesterone in serum samples were plotted against the expected values. The correlation coefficient was 0.997 and a linear regression equation was Y=1.1019+0.9895 X. The mean recovery was 96.86% of the sample replicates ranged from 0.2% to 6%. between assay reproducibility was assessed fro the results obtained from 3 samples which were used for quality control in different assays. The results obtained were in the reference range and were close to each other. Comparison between local and American Dpc reagents for progesterone determination in serum showed high correlation high correlation where r 0.9492.(Author)

    Obesity in reproductive-aged women is associated with a shorter luteal phase and lower progesterone levels. Lipid accumulation in follicles of obese women compromises endoplasmic reticulum (ER) function, activating ER stress in granulosa cells. We hypothesized that ER stress activation in granulosa-lutein cells (GLCs) would modulate progesterone production and contribute to obesity-associated progesterone deficiency. Pretreatment with an ER stress inducer, tunicamycin or thapsigargin, inhibited human chorionic gonadotropin (hCG)-stimulated progesterone production in cultured human GLCs. Pretreatment of human GLCs with tunicamycin inhibited hCG-stimulated expression of steroidogenic acute regulatory protein (StAR) and 3β-hydroxysteroid dehydrogenase (3β-HSD) messenger RNAs (mRNAs) without affecting expression of cytochrome P450 cholesterol side-chain cleavage enzyme (P450scc), as determined by real-time quantitative polymerase chain reaction. Pretreatment with tunicamycin also inhibited hCG-stimulated expression of StAR protein and 3β-HSD enzyme activity in cultured human GLCs, as determined by Western blot analysis and an enzyme immunoassay, respectively, but did not affect hCG-induced intracellular 3',5'-cyclic adenosine monophosphate accumulation. Furthermore, tunicamycin attenuated hCG-induced protein kinase A and extracellular signal-regulated kinase activation, as determined by Western blot analysis. In vivo administration of tunicamycin to pregnant mare serum gonadotropin-treated immature mice prior to hCG treatment inhibited the hCG-stimulated increase in serum progesterone levels and hCG-induced expression of StAR and 3β-HSD mRNA in the ovary without affecting serum estradiol levels or the number of corpora lutea. Our findings indicate that ER stress in the follicles of obese women contributes to progesterone deficiency by inhibiting hCG-induced progesterone production in granulosa cells.

    Milk and hair progesterone contents were determined during the oestrous cycle and gestation in Saanen, F1 crosses (Saanen x Chengdu Mah) and F2 (Saanen x (Saanen x Chengdu Mah)) goats using the radioimmunoassay kits provided by the IAEA. Hair samples were collected from the back of the goats every day from day 1 (after oestrus) to day 28 and every 5 days from day 30 to parturition. Foremilk samples were also collected daily from day 1 to day 20. The results showed that there were significant differences in milk progesterone concentration between pregnant and non-pregnant goats during days 19 to 22 after oestrus. Progesterone in goat hair could be detected using the RIA kits. Hair progesterone content was correlated with the milk progesterone profile during the first 20 days of pregnancy in non-pregnant goats; a similar correlation was observed during the oestrous cycle. When milk samples were collected on day 22 post-oestrus and 3.9 ng/mL was taken as the discriminatory level, the accuracy of pregnancy and non-pregnancy diagnosis was 82.4% and 100% respectively. When hair samples were collected on day 22 and 3.7 ng/50 mg hair was taken as the discriminatory level, the accuracy of pregnancy and non-pregnancy diagnosis was 77.8% and 100% respectively. During gestation, hair progesterone contents increased gradually from day 30 to day 120 and decreased rapidly from day -8 before parturition to parturition. 6 refs, 3 figs, 2 tabs

    The voices of women suffering from postpartum depression are often silent. Women are reluctant to reveal to others that they are unhappy after the birth of their babies. Much has been written on possible causes, risk factors, and treatments for postpartum depression, but little has been done to investigate why women take so long to seek help. Early detection and treatment are key to a full recovery. Childbirth educators are in the position to offer anticipatory guidance on possible complications of the postpartum period, including postpartum depression. This article explores why women with postpartum depression choose to suffer in silence and suggests how childbirth educators can help new mothers find their voices. PMID:20190853

    To identify the effects of foot reflexology massage on fatigue, stress and depression of postpartum women. A nonequivalent control group pre-post design was used. A total of 70 women in a postpartum care center were recruited and were assigned to the experimental group (35) or control group (35). Foot reflexology massage was provided to the experimental group once a day for three days. Data were collected before and after the intervention program which was carried out from December, 2013 to February, 2014. Data were analyzed using Chi-square test, Fisher's exact test, and t-test. The level of fatigue in the experimental group was significantly lower than the control group (t=-2.74, p=.008). The level of cortisol in the urine of women in the experimental group was significantly lower than the control group (t=-2.19, p=.032). The level of depression in the experimental group was significantly lower than the control group (t=-3.00, p=.004). The results show that the foot reflexology massage is an effective nursing intervention to relieve fatigue, stress, and depression for postpartum women.

    A 33-year-old woman presented with acute nonspecific knee pain, 6 months postpartum. MR imaging, computed tomography and radiography were performed and a proximal tibia plateau insufficiency fracture was detected. Bone densitometry demonstrated mild postpartum osteoporosis. To our knowledge these findings have not been described in this location and in this clinical setting. The etiology of the atraumatic fracture of the tibia is presumed to be due to a low bone mineral density. The bone loss was probably due to pregnancy, lactation and postpartum hormonal changes. There were no other inciting causes and the patient was normocalcemic. We discuss the presence of a postpartum stress fracture in a hitherto undescribed site in a patient who had lactated following an uncomplicated pregnancy and had no other identifiable cause for a stress fracture.

    Postpartum depression affects a substantial proportion of new mothers in the United States. Although most employed women return to paid work after birth, the association between duration of maternity leave and postpartum depression is unclear. We therefore aimed to explore this relationship among mothers in the United States. Data included 177 mothers from a national survey who had returned to work full time after having a baby. Multivariable logistic regression was used to explore the independent association between duration of maternity leave and experiencing of postpartum depressive symptoms in the 2 weeks preceding the postpartum survey completion. Overall, duration of maternity leave was not significantly associated with experiencing postpartum depression symptoms (odds ratio [OR], 0.90; 95% confidence interval [CI], 0.80-1.01). This effect, however, varied by duration of maternity leave. Among women who took maternity leaves of 12 weeks or less, every additional week of leave was associated with a lesser odds of experiencing postpartum depressive symptoms (OR, 0.58; 95% CI, 0.40-0.84). Among women who took maternity leaves longer than 12 weeks, leave duration was not associated with postpartum depression symptoms (OR, 0.97; 95% CI, 0.73-1.29). Maternity leaves equaling 12 weeks or less may contribute additional risk for postpartum depressive symptoms, possibly because mothers are juggling employment alongside of important physical and emotional changes during this period. This association underscores the importance of ensuring that mothers have at least 12 weeks of leave from full-time employment after the birth of a baby.

    Despite decades of research demonstrating the role of adult attachment styles and early mother-infant bonding in parenting behaviors and maternal mental health, these constructs have seldom been studied together. The present study aimed to investigate the relationship between attachment styles and specific bonding difficulties of mothers. In addition, as postpartum depression and childbirth-related posttraumatic stress symptoms have been associated with both constructs, we explored their possible mediation effect. One hundred fourteen mothers, 4 to 12 weeks' postpartum, completed a demographic questionnaire, the Adult Attachment Style Questionnaire (M. Mikulincer, V. Florian, & A. Tolmacz, 1990), the Postpartum Bonding Questionnaire (L.F. Brockington, C. Fraser, & D. Wilson, 2006), the Modified Perinatal Posttraumatic Stress Disorder Questionnaire (J.L. Callahan, S.E. Borja, & M.T. Hynan, 2006), and the Edinburgh Postnatal Depression Scale (J.L. Cox, G. Chapman, D. Murray, & P. Jones, 1996), using an online survey system. As predicted, insecure attachment styles were associated with bonding difficulties wherein anxious/ambivalent attachment was associated with greater infant-focused anxiety, mediated by postpartum depression but not childbirth-related PTSD symptoms. In contrast, greater avoidant attachment style was associated with greater rejection and anger, mediated by childbirth-related posttraumatic stress disorder (PTSD), but not depression symptoms. The current study confirmed the association of different attachment styles with bonding as well as the mediating roles of childbirth-related PTSD and postpartum depression symptoms. Future psychological interventions may utilize such evidence to target interventions for bonding disorders in accordance with individual differences. © 2018 Michigan Association for Infant Mental Health.

    The ability of the ascomycete Aspergillus niger N402 to transform exogenous progesterone was investigated. We found that this strain has steroid-hydroxylating activity and can introduce a hydroxyl group into the progesterone molecule mainly at positions C11(α) and C21 with predominant formation of 21-hydroxyprogesterone (deoxycortone). In addition, formation of 6β,11α-dihydroxyprogesterone was also observed. Studying the effects of the growth medium composition and temperature on progesterone conversion by A. niger N402 showed that the most intense accumulation of 21-hydroxyprogesterone occurred in minimal synthetic medium at 28°C. Increasing the cultivation temperature to 37°C resulted in almost complete inhibition of the hydroxylase activity in the minimal medium. In the complete medium, a similar increase in temperature inhibited 11α-hydroxylase activity and completely suppressed 6β-hydroxylase activity, but it produced no effect on 21-hydroxylating activity.

    Full Text Available Postpartum depression is a frequent and disabling condition whose pathophysiology is still unclear. In recent years, the study of the neural correlates of mental disorders has been increasingly approached using magnetic resonance techniques. In this review we synthesize the results from studies on postpartum depression in the context of structural, functional, and spectroscopic magnetic resonance studies of major depression as a whole. Compared to the relative wealth of data available for major depression, magnetic resonance studies of postpartum depression are limited in number and design. A systematic literature search yielded only eleven studies conducted on about one hundred mothers with postpartum depression overall. Brain magnetic resonance findings in postpartum depression appear to replicate those obtained in major depression, with minor deviations that are not sufficient to delineate a distinct neurobiological profile for this condition, due to the small samples used and the lack of direct comparisons with subjects with major depression. However, it seems reasonable to expect that studies conducted in larger populations, and using a larger variety of brain magnetic resonance techniques than has been done so far, might allow for the identification of neuroimaging signatures for postpartum depression.

    Full Text Available Background: Sugammadex has been shown to decrease the efficiency of progesterone-containing oral contraceptive drugs which possess a steroid structure. Aims: The aim of the present study was to evaluate the effects of sugammadex on progesterone levels in pregnant rats as well as on the physiological course of the pregnancy. Study Design: Animal experiment. Methods: This study was approved by the Selçuk University Ethical Committee for Experimental Animal Research. Pregnant Winster Albino rats (n=26 were divided into three groups and administered with various intravenous injections on the 7th day of pregnancy. The control group (Group K, n=6 received 1.5 mL serum physiologic, the sugammadex group (Group S, n=10 received 30 mg/kg sugammadex and the sugammadex + rocuronium group (Group SR, n=10 received 30 mg/kg sugammadex and 3.5 mg/kg rocuronium. Progesterone levels were measured and the offspring were monitored for morphologic status. Results: Mean progesterone levels were 94.16±15.54 ng/mL in Group K, 87.86±12.48 ng/mL in Group S, and 94.53±16.10 ng/mL in Group SR (p>0.05. No stillbirth or miscarriage was observed in the rats. The mean number of offspring was 6.8±1.47 in Group K, 6.5±1.35 in Group S, and 6.4±1.17 in Group SR. The offspring appeared macroscopically normal. Conclusion: Sugammadex does not appear to affect the progesterone levels in pregnant rats in the first trimester and the clinical course. Successful completion of pregnancy and the absence of stillbirth or miscarriage will guide future studies about the use of sugammadex, particularly in the first trimester of the pregnancy.

    Steroid hormones are synthesized from cholesterol in various tissues, mainly in the adrenal glands and gonads. Because these lipid-soluble steroid hormones immediately diffuse through the cells in which they are produced, their secretion directly reflects the activity of the genes related to their production. Progesterone is important not only for luteinization and maintenance of pregnancy, but also as a substrate for most other steroids. Steroidogenic acute regulatory protein (STAR), cytochrome P450 cholesterol side-chain cleavage enzyme (P450scc), and 3β-hydroxysteroid dehydrogenase/Δ(5)-Δ(4) isomerase (3β-HSD) are well-known proteins essential for progesterone production. In addition to them, glutathione S-transferase A1-1 and A3-3 are shown to exert Δ(5)-Δ(4) isomerization activity to produce progesterone in a cooperative fashion with 3β-HSD. 5-Aminolevulinic acid synthase 1, ferredoxin 1, and ferredoxin reductase also play a role in steroidogenesis as accessory factors. Members of the nuclear receptor 5A (NR5A) family (steroidogenic factor 1 and liver receptor homolog 1) play a crucial role in the transcriptional regulation of these genes. The NR5A family activates these genes by binding to NR5A responsive elements present within their promoter regions, as well as to the elements far from their promoters. In addition, various NR5A-interacting proteins including peroxisome proliferator-activated receptor-γ coactivator-1α (PGC-1α), nuclear receptor subfamily 0, group B, member 1 (DAX-1), and CCAAT/enhancer-binding proteins (C/EBP) are involved in the transcription of NR5A target genes and regulate the transcription either positively or negatively under both basal and tropic hormone-stimulated conditions. In this review, we describe the transcriptional regulation of genes related to progesterone production.

    Full Text Available Abstract Background Postpartum weight retention can contribute to obesity. There may be unique barriers to weight loss in this period. Findings Cases are presented for three postpartum women who declined to participate in a postpartum weight loss intervention. Despite their desire to engage in healthier behaviors, or partake in an intervention uniquely designed to promote healthy lifestyles for postpartum women, some find it too difficult to make such commitments. Barriers women face in adopting a healthier lifestyle in this period include 1 time availability; 2 prioritizing other competing life responsibilities above their own health; 3 support from family members, friends, and/or co-workers; and 4 lack of flexibility in the intervention structure. These illustrations describe their perspectives in the context of life balance, perceived health, and support, and reflect the multi-dimensional nature of their lives during the life cycle change of the postpartum period. Conclusion Postpartum women face difficult and complex challenges to prioritizing their health and their weight management.

    The paper presents results of the effect of cadmium on the progesterone synthesis of ovaries. In the current study, we investigated whether Cd also disrupts progesterone synthesis via steroidogenic acute regulatory protein (StAR) and P450 cholesterol side-chain cleavage (P450scc), which play important roles in progesterone synthesis. The Wistar rats were exposed to cadmium in vivo (at 2.5, 5, 7.5 mg/kg, as a single s.c. dose). We showed that the serum P 4 and granule cells P 4 of rats were significantly lower than control group. Ovaries granule cells were incubated in Dulbecco-modified Eagle medium +15% fetal bovine serum with 0, 10, 20, or 40 μM CdCl 2 in vitro, progesterone levels were declined in a dose-dependent manner. Our data showed that the expression of StAR and P450scc in vivo or in vitro were inhibited when treated with CdCl 2 (p 2 treatment; the expression of StAR mRNA and P450scc mRNA in 8-Br-cAMP + 40 μM CdCl 2 were significantly higher than 40 μM CdCl 2 , and were lower than control group. We concluded that StAR, which delivers cholesterol to the inner mitochondrial membrane, is one site at which Cd interferes with progesterone production in cultured rats ovarian granule cells; P450scc, which conveys cholesterol to pregnenolone, is anther site. The mechanisms were mainly controlled by the cAMP-dependent pathway

    The aim of the present study was to prepare solid phase radioimmunoassay (RIA) reagents. Development as well as optimization and validation of RIA system using solid phase magnetic particles for the measurement of progesterone in human serum are described. The production of polyclonal antibodies was carried out by immunizing five white New-Zealand rabbits subcutaneously. Low density magnetizable cellulose iron oxide particles have been used to couple covalently to the IgG fraction of polyclonal anti-progesterone using carbonyl diimidazole activation method and applied as a solid phase separating agent for RIA of serum progesterone. 125 I-progesterone tracer was prepared using chloramine-T and iodogen oxidation methods and purified using high performance liquid chromatography. The progesterone standards were prepared using highly purified progesterone powder with hormone free serum as standard matrix. Optimization and validation of the assay were carried out. The results obtained provide a low cost, simple, sensitive, specific and accurate RIA system of progesterone based on magnetizable solid phase separation. This may be extremely helpful in diagnosis and proper management of ovulation during childbearing years

    Macromolecular components of normal human mammary cytosol (obtained from 'non-malignant tissue samples' from cancer bearing breasts) which bind (/sup 3/H)progesterone in vitro were characterized by sucrose gradient centrifugation, gel filtration on Agarose, ion exchange chromatography, isoelectric focusing, competition studies and kinetic parameters. The size of the cytoplasmic binding components vary with the concentration of KCl. In the absence of KCl, the major components are characterized by sedimentation coefficients of about 4 S and 8 S. In solutions containing 0.3M KCl, the cytoplasmic components sediment at 4 S in sucrose gradient. The corticosteroid-binding component of normal human mammary cytosol both sediment at about the same rate in the presence of 0.3M KCl and chromatograph as a single component on Agarose. The isoelectric point of the progesterone-binding component of normal human mammary cytosol was located around pH 5.0. The progesterone-binding component was more thermo-labile than serum CBG. CBG was inactivated at temperatures above 45 deg C but temperature above 20 deg C destroyed specific progesterone receptor binding. Progesterone receptor concentrations in normal mammary cytosol of premenopausal women depended on the menstrual cycle. The binding of progesterone was highest around the time of ovulation. In breast tumor tissue samples the progesterone receptor concentration was lower than in the normal mammary cytosol (obtained in each case from the same tumor-bearing breast). In 5 out of 37 breast tumor samples progesterone binding activity could not be detected.

    Solution blow spinning (SBS) is a novel technology feasible to produce nanostructured polymeric membranes loaded with active agents. In the present study, nanofibrous mats of poly(lactic acid) (PLA) loaded with progesterone (P4) were produced by SBS at different P4 concentrations. The spun membranes were characterized by scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and Fourier-transform infrared spectroscopy (FTIR). The in vitro releasing of P4 was evaluated using high-performance liquid chromatography (HPLC). Interactions between progesterone and PLA were confirmed by rheological measurements of the PLA/P4 solutions and in the spun mats by microscopy (SEM), thermal (DSC) and spectral (FTIR) analyses. SEM micrographs provided evidences of a smooth and homogeneous structure for nanostructured membranes without progesterone crystals on fiber surface. FTIR spectroscopy indicated miscibility and interaction between the ester of PLA and the ketone groups of the P4 in the nanofibers. X-ray analysis indicated that the size of PLA crystallites increased with progesterone content. Finally, by in vitro release experiments it was possible to observe that the progesterone releasing follows nearly first-order kinetics, probably due to the diffusion of hormone into PLA nanofibers. - Highlights: ► Nanofibers of PLA loading with progesterone were prepared via solution blow spinning. ► Their morphology, FTIR, and XRD and DSC characterization were analyzed. ► Fibers of PLA/progesterone with diameters from 280 to 440 nm were obtained. ► The effect of progesterone content in fiber properties was studied.

    Full Text Available Elena Ali Faculty of Nursing, University of Calgary, Calgary, AB, Canada Purpose: Postpartum anxiety disorders are common and may have significant consequences for mothers and their children. This review examines the literature on women’s experiences with postpartum generalized anxiety disorder (GAD, postpartum panic disorder (PD, obsessive compulsive disorder (OCD, and posttraumatic stress disorder (PTSD. Methods: MEDLINE (Ovid, CINAHL, PsycINFO, and reference lists were searched. Qualitative and quantitative studies assessing women’s experiences with GAD, postpartum PD, OCD, and PTSD were included. Narrative approach to literature synthesis was used. Results: Fourteen studies (among 44 articles met the criteria for review to identify descriptions of women’s cognitive, affective, and somatic experiences related to postpartum anxiety disorders. Loss, frustration, and guilt, accompanied by physical symptoms of tension, were some of the experiences identified across studies. Most women suffered from more than one anxiety disorder, in addition to postpartum depression. To date, research has focused on prevalence rates of postpartum anxiety disorders, and evidence about clinical and subclinical symptoms of postpartum anxiety disorders and outcomes on mother and child is lacking. Postpartum anxiety disorders may have negative effects on parenting and child development; however, the nature of the underlying mechanisms is unclear. Conclusion: More robust longitudinal studies are needed to examine the impact of postpartum GAD, PD, OCD, and PTSD symptoms on the mother and the mother–child relationship to develop targets for therapeutic preventative interventions.

    The post-partum period is a stressful time of change, particularly for immigrant women, but, to the best of the present authors' knowledge, the subject has not been explored. This study aimed to examine immigrant women's post-partum stress, depression, and levels of social support, and to determine the predictors of post-partum stress for Vietnamese immigrant women in Taiwan. A cross-sectional design was used. In this descriptive survey, 208 Vietnamese immigrant women were telephone interviewed by a trained Vietnamese research assistant during one of their 6 weeks post-partum. Data were collected through telephone interviews using three questionnaires, including the Hung Postpartum Stress Scale, Beck Depression Inventory, and Social Support Scale. The result shows that Vietnamese women had low level post-partum stress scores. Participants' family support rated higher than friend support. The incidence of depression was 0.5%. Social support, number of post-partum days, and family income were found to be predictors for post-partum stress, accounting for 26.6% of the variance. The Vietnamese immigrant women experienced significant stress regarding their maternal roles and received most of their support from their families rather than from friends. Nurses caring for this cohort should therefore consider these factors in order to help them cope with their post-partum stress. Healthcare providers should offer available resources to these immigrant women and their spouses during this critical period in their lives. For instance, antenatal education classes could be provided to help immigrant women manage and overcome post-partum issues. © 2015 Japan Academy of Nursing Science.

    Hormones are chemical messengers that regulate many life functions. Deviations from normal hormone levels can have serious health consequences. Accurate measurement of hormone levels in serum can be beneficial in diagnosing, monitoring, and treating a number of diseases. Two steroid hormones, cortisol and progesterone, were selected by the Organic Analysis Working Group (OAWG) to evaluate its member Institutes' measurement capabilities for this important class of measurand. Serum concentrations of cortisol range from 30 ng/mL to 230 ng/mL. Serum concentrations of progesterone in adult females range from 0.15 ng/mL to 25 ng/mL but can rise to approx230 ng/mL during pregnancy. The ability to measure cortisol is indicative of a laboratory's ability to measure steroid hormones at concentration levels similar to cortisol. The ability to measure progesterone is indicative of a laboratory's ability to measure steroid hormones with similar functional groups and concentration levels, such as testosterone. Pilot studies CCQM-P77.a and CCQM-P77.b on the determination of cortisol and progesterone in human serum were completed in 2006. There was good agreement among the results reported by participants who used isotope dilution/mass spectrometry (ID/MS) with either gas chromatography (GC) or liquid chromatography (LC). In 2007 the OAWG decided to proceed with key comparison (KC) CCQM-K63.a, cortisol in human serum, and CCQM-K63.b, progesterone in human serum. Thus, following established OAWG procedure, only results from participants that (1) used an ID/MS-based method, (2) participated in the relevant pilot study, and (3) used a metrologically traceable primary standard were to be eligible for use in calculating the key comparison reference value (KCRV) for each measurand. Six laboratories participated in CCQM-K63.a and eight laboratories participated in CCQM-K63.b. The same pooled frozen female serum material was used in both of the KCs. The mean value for the six ID

    We have investigated the effects administering exogenous progesterone, via insertion of a controlled internal drug release (CIDR) for 4 days, from either day 5 or day 12 of the oestrous cycle on plasma oestradiol concentrations. In study 1, in which progesterone was administered from day 5, measurement of plasma oestradiol in daily samples revealed a significant (p < 0.001) decrease in peripheral oestradiol concentration. In contrast, in study 2, similar administration of progesterone from day 12 had no effect on plasma oestradiol concentration. In study 3, collection of hourly samples following progesterone treatment on day 5 revealed peak progesterone concentrations within 1 h of CIDR insertion and nadir oestradiol concentrations within 4 h. The results demonstrate that treatment with progesterone early in the luteal phase causes a rapid inhibition of oestradiol secretion, while later treatment does not. While improvements in pregnancy rate following progesterone treatment at this time have traditionally been attributed to increases in progesterone, the potential involvement of decreased oestradiol secretion has often been overlooked.

    To examine sociodemographic factors, pregnancy-associated psychosocial stress and depression, health risk behaviors, prepregnancy medical and psychiatric illness, pregnancy-related illnesses, and birth outcomes as risk factors for post-partum depression (PPD). A prospective cohort study screened women at 4 and 8 months of pregnancy and used hierarchical logistic regression analyses to examine predictors of PPD. The study sample include 1,423 pregnant women at a university-based high risk obstetrics clinic. A score of ≥10 on the Patient Health Questionnaire-9 (PHQ-9) indicated clinically significant depressive symptoms. Compared with women without significant postpartum depressive symptoms, women with PPD were significantly younger (pdepressive symptoms (pdepression case finding for pregnant women.

    The use of progesterone for luteal phase support has been demonstrated to be beneficial in assisted reproduction cycles using gonadotrophin-releasing hormone analogues (GnRHa). Two micronized progesterone preparations are available for vaginal administration: capsules and gel. The objective of this study was to compare the efficacy of these two forms for luteal phase support in assisted reproduction cycles. A total of 244 couples undergoing IVF/intracytoplasmic sperm injection cycles were included in the study and were randomly allocated (sealed envelopes) into two groups: group 1 (122) received vaginal capsules of 200 mg of micronized progesterone (Utrogestan), 3 times daily, and group 2 (122) received micronized progesterone in gel (Crinone 8%), once daily. Both groups received progesterone for 13 days beginning day 1 after oocyte retrieval, continuing until the pregnancy test was performed and until 12 weeks of pregnancy. Groups were compared by clinical data and assisted reproduction results and had similar ages and causes of infertility. Although the pregnancy rate was higher for those receiving progesterone gel than capsules (44.26 and 36.06% respectively), this difference was not statistically significant. The study showed that vaginal progesterone gel and capsules used for luteal phase support in assisted reproduction cycles with long protocol GnRHa result in similar pregnancy rates.

Methods: The study included mothers and their newborns insured by the Helsana health insurance group in Switzerland and who delivered between January 2012 and May 2013 in the canton of Basel Stadt (BS (intervention canton. We compared monthly post-discharge costs before the launch of a coordinated postpartum care model (control phase, n = 144 to those after its introduction (intervention phase, n = 92. Costs in the intervention canton were also compared to those in five control cantons without a coordinated postpartum care model (cross-sectional control group: n = 7, 767. Results: The average monthly post-discharge costs for mothers remained unchanged in the seven months following the introduction of a coordinated postpartum care model, despite a higher use of midwife services (increasing from 72% to 80%. Likewise, monthly costs did not differ between the intervention canton and five control cantons. In multivariate analyses, the ambulatory costs for mothers were not associated with the post-intervention phase. Cross-sectionally, however, they were positively associated with midwifery use. For children, costs in the post-intervention phase were lower in the first month after hospital discharge compared to the pre-intervention phase (difference of –114 CHF [95%CI –202 CHF to –27 CHF], yet no differences were seen in the cross-sectional comparison. Conclusions: The introduction of a coordinated postpartum care model was associated with decreased costs for neonates in the first month after hospital discharge. Despite increased midwifery use, costs for mothers remained unchanged.

    A suspension of microcrystalline cellulose with bonded globulin fraction of the polyclonal antibody against progesterone was prepared and applied to the radioimmunoanalysis of progesterone in full milk and in blood serum. The results were compared with those obtained using RETRO-test kits; the comparison gave evidence that the novel technique can fully replace the RETRO-test, the elimination of the separating medium (activated carbon, polyethylene glycol) being an asset. The obtained correlation coefficient and regression equation for a simultaneous determination of 120 samples by the two methods were r = 0.964 and y = 1.113x - 0.939, respectively

    Full Text Available OBJECTIVE: We investigated associations between maternal postpartum distress covering anxiety, depression and stress and childhood overweight. METHODS: We performed a prospective cohort study, including 21,121 mother-child-dyads from the Danish National Birth Cohort (DNBC. Maternal distress was measured 6 months postpartum by 9 items covering anxiety, depression and stress. Outcome was childhood overweight at 7-years-of age. Multiple logistic regression analyses were performed and information on maternal age, socioeconomic status, pre-pregnancy BMI, gestational weight gain, parity, smoking during pregnancy, paternal BMI, birth weight, gestational age at birth, sex, breastfeeding and finally infant weight at 5 and 12 month were included in the analyses. RESULTS: We found, that postpartum distress was not associated with childhood risk of overweight, OR 1.00, 95%CI [0.98-1.02]. Neither was anxiety, depression, or stress exposure, separately. There were no significant differences between the genders. Adjustment for potential confounders did not alter the results. CONCLUSION: Maternal postpartum distress is apparently not an independent risk factor for childhood overweight at 7-years-of-age. However, we can confirm previous findings of perinatal determinants as high maternal pre-pregnancy BMI, and smoking during pregnancy being risk factors for childhood overweight.

    Cocaine abuse in pregnant women is currently a significant public hygiene problem and is tightly associated with elevated risk for preterm delivery. Placental steroidogenesis especially progesterone production was essential for success and maintenance of pregnancy in humans and rodents. In the present study, we determined the impact of prenatal cocaine exposure on pathways of placental progesterone synthesis in rats. Pregnant rats were treated cocaine twice daily (15 mg/kg/day) during the third trimester, and the maternal and fetal plasma progesterone and pregnenolone concentrations were detected. We also examined both the protein and mRNA expression of some key enzymes and regulators for progesterone production in placenta. Results showed that, after maternal cocaine use during pregnancy, progesterone and pregnenolone concentrations in both maternal and fetal rats were significantly decreased. Although prenatal cocaine exposure had no effects on placental 3β-hydroxysteroid dehydrogenase type 1 (3βHSD1) expression, protein and mRNA expression of the cholesterol side-chain cleavage enzyme (P450scc/CYP11a) in placenta was significantly inhibited. Moreover, protein and mRNA expressions of MLN64 that regulating cholesterol transport and activating protein 2γ (AP2γ/Tfap2c) that controlling P450scc/CYP11a gene expression in placenta were both decreased following maternal cocaine use in pregnancy. Collectively, this study suggested that prenatal cocaine exposure could insult the placental progesterone production in rats possibly associated with the high risk for preterm delivery.

    The relative binding affinities (RBAs) of four progestational compounds (norethisterone, levonorgestrel, 3-keto-desogestrel and gestodene) for the human progesterone and androgen receptors were measured in MCF-7 cytosol and intact MCF-7 cells. For the binding to the progesterone receptor, both Org 2058 and Org 3236 (or 3-keto-desogestrel) were used as labelled ligands. The following ranking (low to high) for the RBA of the nuclear (intact cells) progesterone receptor irrespective of the ligand used is found: norethisterone much less than levonorgestrel less than 3-keto-destogestrel less than gestodene. The difference between the various progestagens is significant with the exception of that between 3-keto-desogestrel and gestodene, when Org 2058 is used as ligand. For the cytosolic progesterone receptor, the same order is found with the exception that similar RBAs are found for gestodene and 3-keto-desogestrel. The four progestagens clearly differ with respect to binding to the androgen receptor using dihydrotestosterone as labelled ligand in intact cells; the ranking (low to high) is: norethisterone less than 3 keto-desogestrel less than levonorgestrel and gestodene. The difference between 3-keto-desogestrel and levonorgestrel or gestodene is significant. The selectivity indices (ratio of the mean RBA for the progesterone receptor to that of androgen receptor) in intact cells are significantly higher for 3-keto-desogestrel and gestodene than for levonorgestrel and norethisterone. From these results we conclude that the introduction of the 18-methyl in norethisterone (levonorgestel) increases both the binding to the progesterone and androgen receptors

    Progesterone is essential for establishment and maintenance of pregnancy in mammals. The objective of this study was to examine the effect of elevating progesterone during the different physiological stages of early embryo development on embryo survival. Estrus was synchronized in cross-bred beef heifers (n=197, approximately 2-years old) and they were inseminated 12-18h after estrus onset (=Day 0). Inseminated heifers were randomly assigned to 1 of 3 treatments: (1) Control, n=69; (2) progesterone supplementation using a Controlled Internal Drug Release Device (CIDR) from Day 3 to 6.5, n=64; or (3) progesterone supplementation using a CIDR from Day 4.5 to 8, n=64. Body condition (BCS) and locomotion scores (scale of 1-5) were recorded for all animals. Animals with a locomotion score >/=4 (very lame) were excluded. Embryo survival rate was determined at slaughter on Day 25. Conceptus length and weight were recorded and the corpus luteum (CL) of all pregnant animals was dissected and weighed. Supplementation with exogenous progesterone increased (Prate compared with controls. Mean CL weight, conceptus length and conceptus weight were not different between treatments. There was a positive relationship (Prate in treated heifers and a similar trend existed between the increase from Days 4.5 to 8 (Prate in treated heifers. A direct correlation was seen between locomotion score and embryo survival rate, with higher (Prates in heifers with a lower locomotion score. In conclusion, supplementation with progesterone at different stages of early embryo development increased peripheral progesterone concentration and resulted in a positive association between changes in progesterone concentration during the early luteal phase and embryo survival rate. Supplementation with progesterone had no effect on either CL weight or conceptus size in pregnant animals. Lameness had a significant negative effect on early embryo survival.

    Postpartum depression (PPD), a significant health problem affecting about 19.4% of postpartum women worldwide, may result in long-term cognitive and behavior problems in children, spousal depression, widespread family dysfunction, and chronic and increasingly severe maternal depression. Although current theoretical frameworks provide a rich context for studying PPD,none provides a framework that specifically addresses the dynamic relationship of the inner personal experience with the social and cultural context of PPD. The authors propose the social energy exchange theory for postpartum depression to understand how PPD impedes this dynamic relationship and suggest it as a theoretical framework for the study of interventions that would target intra- and interpersonal disturbance within the social and cultural context.

    It is well established that social recognition memory is mediated, in part, by arginine vasopressin (AVP). AVP cells within the bed nucleus of the stria terminalis (BST) and medial amygdala (MeA) send AVP-ergic projections to the lateral septum (LS). We have demonstrated that progesterone treatment decreases AVP immunoreactivity within the BST, the MeA and the LS, and that progesterone treatment impairs social recognition. These data suggested that progesterone may impair social recognition memory by decreasing AVP. In the present experiment, we hypothesized that infusions of AVP into the LS would rescue the progesterone induced impairment in social recognition within adult male rats. One week after adult male rats underwent cannula surgery, they were given systemic injections of either a physiological dose of progesterone or oil control for three days. Four hours after the last injection, we tested social recognition memory using the social discrimination paradigm, a two-trial test that is based on the natural propensity for rats to be highly motivated to investigate novel conspecifics. Immediately after the first exposure to a juvenile, each animal received bilateral infusions of either AVP or artificial CSF (aCSF) into the LS. Our results show that, as expected, control animals exhibited normal social discrimination. In corroboration with our previous results, animals given progesterone have impaired social discrimination. Interestingly, animals treated with progesterone and AVP exhibited normal social discrimination, suggesting that AVP treatment rescued the impairment in social recognition caused by progesterone. These data also further support a role for progesterone in modulating vasopressin dependent behavior within the male brain. PMID:23639881

    Sympathetic innervations exist in mammalian CL. The action of catecholaminergic system on luteal cells has been the focus of a variety of studies. Norepinephrine (NE) increased progesterone secretion of cattle luteal cells by activating β-adrenoceptors. In this study, murine luteal cells were treated with NE and isoprenaline (ISO). We found that NE increased the viability of murine luteal cells and ISO decreased the viability of luteal cells. Both NE and ISO promoted the progesterone production. Nonselective β-adrenergic antagonist, propranolol reversed the effect of ISO on cell viability but did not reverse the effect of NE on cell viability. Propranolol blocked the influence of NE and ISO on progesterone production. These results reveal that the increase of luteal cell viability induced by NE is not dependent on β-adrenergic activation. α-Adrenergic activation possibly contributes to it. Both NE and ISO increased progesterone production through activating β-adrenergic receptor. Further study showed that CyclinD2 is involved in the increase of luteal cell induced by NE. 3β-Hydroxysteroid dehydrogenase, LHR, steroidogenic acute regulatory protein (StAR), and PGF2α contribute to the progesterone production induced by NE and ISO.

    2017-10-01

    Autoimmune progesterone dermatitis (APD) is a cyclical cutaneous reaction to progesterone, with symptoms that typically begin 3-10 days before the onset of menstrual flow and end 1-2 days into menses. The symptoms vary in severity from barely visible to anaphylaxis, but most often include an eczematous eruption, erythema multiforme, urticaria, folliculitis, and angioedema. This is a rare disorder with only a handful of documented cases. The pathogenesis of this condition remains unknown and significant variations in the presentation and severity of symptoms complicates its diagnosis. Treatment seeks to inhibit progesterone secretion through suppression of ovulation, but it may be unsuccessful. We present a case of autoimmune progesterone dermatitis that eluded diagnosis for several years, and subsequently the patient was completely controlled with oral contraceptive pills.

    A decline in serum progesterone or antagonism of progesterone receptor function results in preterm labor and birth. Whether characteristics of premature remodeling of the cervix after antiprogestins or ovariectomy are similar to that at term was the focus of the present study. Groups of pregnant rats were treated with vehicle, a progesterone receptor antagonist (onapristone or mifepristone), or ovariectomized on day 17 postbreeding. As expected, controls given vehicle delivered at term while rats delivered preterm after progesterone receptor antagonist treatment or ovariectomy. Similar to the cervix before term, the preterm cervix of progesterone receptor antagonist-treated rats was characterized by reduced cell nuclei density, decreased collagen content and structure, as well as a greater presence of macrophages per unit area. Thus, loss of nuclear progesterone receptor-mediated actions promoted structural remodeling of the cervix, increased census of resident macrophages, and preterm birth much like that found in the cervix at term. In contrast to the progesterone receptor antagonist-induced advance in characteristics associated with remodeling, ovariectomy-induced loss of systemic progesterone did not affect hypertrophy, extracellular collagen, or macrophage numbers in the cervix. Thus, the structure and macrophage census in the cervix appear sufficient for premature ripening and birth to occur well before term. With progesterone receptors predominantly localized on cells other than macrophages, the findings suggest that interactions between cells may facilitate the loss of progesterone receptor-mediated actions as part of a final common mechanism that remodels the cervix in certain etiologies of preterm and with parturition at term.

    Solution blow spinning (SBS) is a novel technology feasible to produce nanostructured polymeric membranes loaded with active agents. In the present study, nanofibrous mats of poly(lactic acid) (PLA) loaded with progesterone (P4) were produced by SBS at different P4 concentrations. The spun membranes were characterized by scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and Fourier-transform infrared spectroscopy (FTIR). The in vitro releasing of P4 was evaluated using high-performance liquid chromatography (HPLC). Interactions between progesterone and PLA were confirmed by rheological measurements of the PLA/P4 solutions and in the spun mats by microscopy (SEM), thermal (DSC) and spectral (FTIR) analyses. SEM micrographs provided evidences of a smooth and homogeneous structure for nanostructured membranes without progesterone crystals on fiber surface. FTIR spectroscopy indicated miscibility and interaction between the ester of PLA and the ketone groups of the P4 in the nanofibers. X-ray analysis indicated that the size of PLA crystallites increased with progesterone content. Finally, by in vitro release experiments it was possible to observe that the progesterone releasing follows nearly first-order kinetics, probably due to the diffusion of hormone into PLA nanofibers. - Highlights: Black-Right-Pointing-Pointer Nanofibers of PLA loading with progesterone were prepared via solution blow spinning. Black-Right-Pointing-Pointer Their morphology, FTIR, and XRD and DSC characterization were analyzed. Black-Right-Pointing-Pointer Fibers of PLA/progesterone with diameters from 280 to 440 nm were obtained.

    In this study, we aimed to investigate whether progesterone-induced acrosome reaction (AR) rate could be an indicator for fertilisation rate in vitro. Twenty-six couples with unexplained infertility and undergoing in vitro fertilisation (IVF) treatment were involved. On the oocytes retrieval day after routine IVF, residual sperm samples were collected to receive progesterone induction (progesterone group) or not (control group). AR rate was calculated and fertilisation rate was recorded. The correlation between progesterone-induced AR and fertilisation rate and between sperm normal morphology and 3PN (tripronuclear) were analysed using the Spearman correlation analysis. The AR rate of progesterone group was statistically higher than that of the control group (15.6 ± 5.88% versus 9.66 ± 5.771%, P rate (r = -0.053, P > 0.01) or rate of high-quality embryo development (r = -0.055, P > 0.01). Normal sperm morphology also showed no significant correlation with the amount of 3PN zygotes (r = 0.029, P > 0.01), rate of 3PN zygotes production (r = 0.20, P > 0.01), rate of 3PN embryo development (r = -0.406, P > 0.01), fertilisation rate (r = -0.148, P > 0.01) or progesterone-induced AR rate (r = 0.214, P > 0.01). Progesterone can induce AR in vitro significantly; however, the progesterone-induced AR may not be used to indicate fertilisation rate. © 2014 Blackwell Verlag GmbH.

    To investigate chromosomal radiosensitivity of lymphocytes the micronucleus (MN) assay has been used for many years. The results of these studies suggest the use of the MN assay as a biomarker for cancer predisposition. However, the MN assay has still some limitations associated with the reproducibility and sensitivity. Especially a high intra-individual variability has been observed. An explanation for this high intra-individual variability is not yet available. In literature it is suggested that the high variability among females is attributable to hormonal status. In this study we investigated if the high intra-individual variability in micronucleus formation in lymphocytes of females after in vitro exposure to ionising radiation is caused by variations in hormone levels of estradiol (E2) and progesterone (PROG). For this, the MN assay was performed on blood samples of 18 healthy women during 7 consecutive weeks while the estradiol and progesterone levels were determined at the same time. The MN assay was also examined in cultures of isolated blood lymphocytes with estradiol or progesterone levels added in vitro. The results demonstrated that estradiol and progesterone levels have no influence on the variations in radiation-induced MN yields observed in blood samples of healthy women. These conclusions were confirmed by the 'in vitro' experiments as no correlation between the MN yields and the concentrations of hormones (estradiol or progesterone) added in vitro to isolated lymphocytes cultures was observed

    A number of synthetic steroids are capable of modulating progesterone receptors with a spectrum of activities ranging from pure antagonism to a mixture of agonism and antagonism. The best known of these are mifepristone (RU 486), asoprisnil (J 867), onapristone (ZK 98299), ulipristal (CDB 2914), Proellex() (CDB 4124), ORG 33628 and ORG 31710. Outside reproduction selective modulators of progesterone receptors have been under investigation for a large variety of indications, for example in oncology as adjuvants in breast, cervical, endometrial, ovarian and prostate cancer, as well as inoperable meningioma and leiomyosarcoma. In addition, they have been used as antiglucocorticoids. It is therefore useful to review the results obtained in these conditions. A careful evaluation of existing major review papers and of recently published articles was carried out for the indications under review, focusing not only on mifepristone but also on those other selective modulators of progesterone receptors for which data are available. In preliminary studies selective modulators of progesterone receptors had some activity on a number of neoplasias. Their antiglucocorticoid activity has been tested with some success in Cushing's syndrome, several psychiatric conditions (e.g., mood disorders and Alzheimer's disease) and acute renal failure. Finally they are being used in a gene regulator system.

    Uterine fibroids are common in women of reproductive age and can have a significant impact on quality of life and fertility. Although a number of international obstetrics/gynecology societies have issued evidence-based clinical practice guidelines for the management of symptomatic uterine fibroids, many of these guidelines do not yet reflect the most recent clinical evidence and approved indication for one of the key medical management options: the selective progesterone receptor modulator class. This article aims to share the clinical experience gained with selective progesterone receptor modulators in Europe and Canada by reviewing the historical development of selective progesterone receptor modulators, current best practices for selective progesterone receptor modulator use based on available data, and potential future uses for selective progesterone receptor modulators in uterine fibroids and other gynecologic conditions.

    Neurologic complications of post-partum are serious and usually secondary to eclampsia or stroke. We here report a 26-year-old female who presented with severe headaches, blurred vision, and repeated generalized seizures secondary to posterior reversible encephalopathy that occurred after a caesarean section for fetal death in utero. Outcome was favourable. Although uncommon, this neurologic complication of the post-partum should be discussed in the presence of any sign of encephalopathy occurring in the context of acute hypertension.

    Progesterone plays critical roles in maintaining a successful pregnancy at the early embryonic stage. Human chorionic gonadotropin (hCG) rapidly induces amphiregulin (AREG) expression. However, it remains unknown whether AREG mediates hCG-induced progesterone production. Thus, the objective of this study was to investigate the role of AREG in hCG-induced progesterone production and the underlying molecular mechanism in human granulosa cells; primary cells were used as the experimental model. ...

    This cross-sectional correlational study examined post-partum depression and its relationship with demographic, maternal, and infant health problems in urban Jordanian women. Participants (n = 315) were selected from five maternal child healthcare centers and one major hospital in Amman, Jordan. Patient Health Questionnaire-9 was used to measure post-partum depression within 12 weeks of birth. A number of socio-demographic and health problems were examined for an association with post-partum depression. Results showed that 25% of post-partum women suffered moderate to severe depression and 50% of the sample had mild depression. None of the socio-demographic variables (age, education, employment, income) were significantly related to post-partum depression; however, two obstetric/infant variables (mode of birth and breastfeeding), were significantly associated with post-partum depression. There was a significant association between post-partum depression and 15 health problems of obstetric, gynecologic (i.e. episiotomy pain, infection), and general health conditions (i.e. fatigue, headache). Nurses and midwives need to emphasize post-partum depression screening, follow-up, and proper management of maternal and infant health factors predisposing to post-partum depression rather than merely focusing on women's inherent demographic factors. © 2015 Wiley Publishing Asia Pty Ltd.

    2016-01-01

    Post-partum period is associated with specific characteristics in women with gestational disorders or preeclampsia. For breastfeeding women, the choice of antihypertensive treatment should take into account the impact on child health. The impact of breastfeeding on health mother must be also discussed. Moreover, for lactation inhibition, bromocriptine should not be used, especially in the context of gestational disorders. In post-partum period, the best contraceptive strategy is only-progestin contraception or non-hormonal contraceptives use. However, this choice will depend on the stabilization or normalization of blood pressure in early post-partum period. Finally, several consultations should be suggested: an information and announcement to explain the consequences of these gestational disorders and organize their multidisciplinary management and follow-up. A preconceptional consultation takes its place to anticipate potential recurrent preeclampsia or gestational hypertension and to schedule a future pregnancy in optimal conditions. Copyright © 2016.

    1984-08-01

    Plasma progesterone levels in female prairie dogs were determined by a radioimmunoassay specific for progesterone. Plasma progesterone levels were determined in samples taken before estrus, at estrus, during the luteal phase, and during anestrus from females maintained all year in the laboratory. Progesterone levels were also determined in plasma samples taken in the laboratory from two pregnant and three postparturient females captured in the field. Progesterone levels were low before estrus and continued low during estrus. They rose on the first week after estrus to 0.8 ng/ml or above and continued at or above this level for 9-14 weeks following estrus. Gestation in prairie dogs is 35 days in this species. Progesterone levels of three postparturient females were above 1.0 ng/ml for 7 weeks after their arrival in the laboratory. These females all had uterine scars showing that they had delivered their litters before they were captured. Two females were determined to be pregnant at the time of their capture. These females later reabsorbed their fetuses (determined by laparotomy). Progesterone values of samples from these females were all above 1.0 ng/ml except for one low value in one female which occurred 3 weeks after her capture and after reabsorption of her fetuses was in progress. The cells of the corpus lutea (CL) of nonpregnant, pregnant, and postparturient females had well-developed rings of cytoplasmic basophilia but as the CL regressed this pattern became disorganized and disappeared. The function of this basophilia is not known. The long luteal phase found in female prairie dogs is compared to those found in other species of mammals. This is the first annually breeding rodent reported to have a longer luteal phase that the period of gestation.

    Full Text Available Abstract Background As a matter of routine, midwives in Sweden have spoken with women about their experiences of labour in a so-called 'postpartum consultation'. However, the possibility of offering women this kind of consultation today is reduced due to shortage of both time and resources. The aim of this study was to explore the occurrence, women's requirements of, and experiences of a postpartum consultation, and to identify expectations from women who wanted but did not have a consultation with the midwife assisting during labour. Methods All Swedish speaking women who gave birth to a live born child at a University Hospital in western Sweden were consecutively included for a phone interview over a three-week period. An additional phone interview was conducted with the women who did not have a postpartum consultation, but who wanted to talk with the midwife assisting during labour. Data from the interviews were analysed using qualitative content analysis. Results Of the 150 interviewed women, 56% (n = 84 had a postpartum consultation of which 61.9% (n = 52 had this with the midwife assisting during labour. Twenty of the 28 women who did not have a consultation with anyone still desired to talk with the midwife assisting during labour. Of these, 19 were interviewed. The content the women wanted to talk about was summarized in four categories: to understand the course of events during labour; to put into words, feelings about undignified management; to describe own behaviour and feelings, and to describe own fear. Conclusion The survey shows that the frequency of postpartum consultation is decreasing, that the majority of women who give birth today still require it, but only about half of them receive it. It is crucial to develop a plan for these consultations that meets both the women's needs and the organization within current maternity care.

    A novel progesterone immunosensor using a colloidal gold-graphite-Teflon-tyrosinase composite biosensor as amperometric transducer is reported. A sequential competitive configuration between the analyte and progesterone labelled with alkaline phosphatase (AP) was used. Phenyl phosphate was employed as the AP-substrate and the enzyme reaction product, phenol, was oxidized by tyrosinase to o-quinone, which is subsequently reduced at -0.1 V at the biocomposite electrode. Variables such as the concentration of phenyl phosphate, the amount of antibody attached to the electrode surface, immersion time in a 2% BSA solution, working pH and incubation times in progesterone and AP conjugate were optimized. A linear calibration graph for progesterone was obtained between 0 and 40 ng mL -1 with a slope value of -82.3 nA ng -1 mL, and a detection limit of 0.43 ng mL -1 . The time needed to reach the steady-state current from the addition of phenyl phosphate was 30-40 s. These analytical characteristics improve substantially those reported for other progesterone immunosensors. A lifetime of 14 days with no need to apply any regeneration procedure was also achieved. The usefulness of the immunosensor was evaluated by determining progesterone in milk samples spiked with the analyte at 5.0 and 1.5 ng mL -1 concentration levels. Following a very simple procedure, involving only sample dilution, mean recoveries (n = 7) of 98 ± 3% and 99 ± 3%, respectively, were obtained

    Newborns are particularly susceptible to bacterial infections due to qualitative and quantitative deficiencies of the neonatal innate immune system. However, the mechanisms underlying these deficiencies are poorly understood. Given that fetuses are exposed to high concentrations of estradiol and progesterone during gestation and at time of delivery, we analyzed the effects of these hormones on the response of neonatal innate immune cells to endotoxin, bacterial lipopeptide, and Escherichia coli and group B Streptococcus, the two most common causes of early-onset neonatal sepsis. Here we show that at concentrations present in umbilical cord blood, estradiol and progesterone are as powerful as hydrocortisone for inhibition of cytokine production by cord blood mononuclear cells (CBMCs) and newborn monocytes. Interestingly, CBMCs and newborn monocytes are more sensitive to the effects of estradiol and progesterone than adult peripheral blood mononuclear cells and monocytes. This increased sensitivity is associated with higher expression levels of estrogen and membrane progesterone receptors but is independent of a downregulation of Toll-like receptor 2 (TLR2), TLR4, and myeloid differentiation primary response gene 88 in newborn cells. Estradiol and progesterone mediate their anti-inflammatory activity through inhibition of the NF-κB pathway but not the mitogen-activated protein kinase pathway in CBMCs. Altogether, these results suggest that elevated umbilical cord blood concentrations of estradiol and progesterone acting on mononuclear cells expressing high levels of steroid receptors contribute to impair innate immune responses in newborns. Therefore, intrauterine exposure to estradiol and progesterone may participate in increasing susceptibility to infection during the neonatal period. PMID:21518785

    Organotin compounds, such as tributyltin (TBT) and triphenyltin (TPT), are typical environmental contaminants and suspected endocrine-disrupting chemicals because they cause masculinization in female mollusks. In addition, previous studies have suggested that the endocrine disruption by organotin compounds leads to activation of peroxisome proliferator-activated receptor (PPAR)γ and retinoid X receptor (RXR). However, whether organotin compounds cause crucial toxicities in human development and reproduction is unclear. We here investigated the structure-dependent effect of 12 tin compounds on mRNA transcription of 3β-hydroxysteroid dehydrogenase type I (3β-HSD I) and progesterone production in human choriocarcinoma Jar cells. TBT, TPT, dibutyltin, monophenyltin, tripropyltin, and tricyclohexyltin enhanced progesterone production in a dose-dependent fashion. Although tetraalkyltin compounds such as tetrabutyltin increased progesterone production, the concentrations necessary for activation were 30-100 times greater than those for trialkyltins. All tested active organotins increased 3β-HSD I mRNA transcription. We further investigated the correlation between the agonistic activity of organotin compounds on PPARγ and their ability to promote progesterone production. Except for DBTCl2, the active organotins significantly induced the transactivation function of PPARγ. In addition, PPARγ knockdown significantly suppressed the induction of mRNA transcription of 3β-HSD I by all active organotins except DBTCl2. These results suggest that some organotin compounds promote progesterone biosynthesis in vitro by inducing 3β-HSD I mRNA transcription via the PPARγ signaling pathway. The placenta represents a potential target organ for these compounds, whose endocrine-disrupting effects might cause local changes in progesterone concentration in pregnant women.

  13. Vasopressin infusion into the lateral septum of adult male rats rescues progesterone-induced impairment in social recognition.

    It is well established that social recognition memory is mediated, in part, by arginine vasopressin (AVP). AVP cells within the bed nucleus of the stria terminalis (BST) and medial amygdala (MeA) send AVP-ergic projections to the lateral septum (LS). We have demonstrated that progesterone treatment decreases AVP immunoreactivity within the BST, the MeA and the LS, and that progesterone treatment impairs social recognition. These data suggested that progesterone may impair social recognition memory by decreasing AVP. In the present experiment, we hypothesized that infusions of AVP into the LS would rescue the progesterone-induced impairment in social recognition within adult male rats. One week after adult male rats underwent cannula surgery, they were given systemic injections of either a physiological dose of progesterone or oil control for 3 days. Four hours after the last injection, we tested social recognition memory using the social discrimination paradigm, a two-trial test that is based on the natural propensity for rats to be highly motivated to investigate novel conspecifics. Immediately after the first exposure to a juvenile, each animal received bilateral infusions of either AVP or artificial cerebrospinal fluid into the LS. Our results show that, as expected, control animals exhibited normal social discrimination. In corroboration with our previous results, animals given progesterone have impaired social discrimination. Interestingly, animals treated with progesterone and AVP exhibited normal social discrimination, suggesting that AVP treatment rescued the impairment in social recognition caused by progesterone. These data also further support a role for progesterone in modulating vasopressin-dependent behavior within the male brain. Copyright © 2013 IBRO. Published by Elsevier Ltd. All rights reserved.

    Effect of female sex hormones on the production/release of adipocyte-derived cytokines has been debatable. Furthermore, whether the cellular signaling triggered by these hormones involve Rho-kinase has not been investigated yet. Therefore, in this study, effects of 17β-estradiol and progesterone as well as the Rho-kinase inhibitor, Y-27632 on the level of adipokines such as resistin, adiponectin, leptin, TNF-α and IL-6 were investigated in 3T3-L1-derived adipocytes. Differentiation was induced in the post-confluent preadipocytes by the standard differentiation medium (Dulbecco's modified Eagle's medium with 10% fetal bovine serum together with the mixture of isobutylmethylxanthine, dexamethasone and insulin) in the presence of 17β-estradiol (10(-8)-10(-7)M), progesterone (10(-6)-10(-5)M), the Rho-kinase inhibitor, Y-27632 (10(-5)M) and their combination for 8days. Measurements of the adipokines were performed in the culturing medium by ELISA kits using specific monoclonal antibodies. 17β-estradiol elevated resistin but decreased adiponectin and IL-6 levels; however, it did not alter the concentration of leptin and TNF-α. Y-27632 pretreatment inhibited the rise of resistin and the fall of adiponectin by 17β-estradiol without any effects by its own. Progesterone did not change resistin, leptin and TNF-α level; however, it elevated adiponectin and decreased IL-6 production. Neither 17β-estradiol nor Y-27632 was able to antagonize the increase of adiponectin and the reduction of IL-6 levels by progesterone. While Y-27632 alone lowered IL-6 level, it increased leptin and TNF-α concentration without altering resistin and adiponectin. In conclusion, 17β-estradiol could modify adipokine production in 3T3-L1 adipocytes with the actions some of which involve Rho-kinase mediation. Copyright © 2015 Elsevier Ltd. All rights reserved.

    although psychosocial risk factors have been identified for postpartum depression (PPD) and perinatal posttraumatic stress disorder (PTSD), the role of labour- and birth-related factors remains unclear. The present investigation explored the impact of birth setting, subjective childbirth experience, and their interplay, on PPD and postpartum PTSD. in this prospective longitudinal cohort study, three groups of women who had vaginal births at a tertiary care hospital, a birthing center, and those transferred from the birthing centre to the tertiary care hospital were compared. Participants were followed twice during pregnancy (12-14 and 32-34 weeks gestation) and twice after childbirth (1-3 and 7-9 weeks postpartum). symptoms of PPD and PTSD did not significantly differ between birth groups; however, measures of subjective childbirth experience and obstetric factors did. Moderation analyses indicated a significant interaction between pain and birth group, such that higher ratings of pain among women who were transferred was associated with greater symptoms of postpartum PTSD. women who are transferred appear to have a unique experience that may put them at greater risk for postpartum psychological distress. It may be beneficial for care providers to help prepare women for pain management and potential unexpected complications, particularly if it is their first childbirth. Copyright © 2017 Elsevier Ltd.

    To assess why postpartum women who desired long-acting reversible contraception (LARC) did not receive it in the postpartum period and to assess which contraceptive methods they were using instead. This was a subgroup analysis of 324 women enrolled in a randomized, controlled trial to receive or not receive an educational LARC script during their postpartum hospitalization. Participants in this subgroup analysis stated that they were either using LARC (n = 114) or interested in using LARC (n = 210) during a follow-up survey completed after their scheduled 6-week postpartum visit. Modified Poisson regression analysis was used to assess for characteristics associated with using LARC by the time of the follow-up survey. Women who were interested in LARC but not using it were more likely to be multiparous (relative risk [RR], 1.59; 95% CI, 1.19-2.11) and to have missed their postpartum visit (RR, 25.88; 95% CI, 3.75-178.44) compared with those using LARC. Among the interested 210 who were not using LARC, the most common reasons provided for non-use were that they were told to come back for another insertion visit (45%), missed the postpartum visit (26%), and could not afford LARC (11%). The most common contraceptive methods used instead of LARC were barrier methods (42%) and abstinence (19%); 18% used no contraceptive method. Two-thirds (65%) of postpartum women who desired to use LARC did not receive it in the postpartum period and used less effective contraceptive methods. Increasing access to immediate postpartum LARC and eliminating two-visit protocols for LARC insertion may increase postpartum LARC use. As the Affordable Care Act moves toward full implementation, it is necessary to understand the barriers that prevent interested patients from receiving LARC.

    Objective: To analyze the arterial supply in postpartum hemorrhage and to evaluate the clinical value of arteriography in transcatheter arterial embolization (TAE) for treating postpartum hemorrhage. Methods: The arteriography of 37 patients with postpartum hemorrhage was analyzed. TAE were performed after the bleeding artery was identified. Post TAE angiography was performed to confirm the success of embolization. Results: The bleeding artery in atonic uterus and abnormal placenta was the uterine artery. The bleeding artery in birth canal laceration is mainly non-uterine artery. Postpartum hemorrhage was successfully controlled in all 37 patients without sever complication of TAE. Conclusion: Arteriography in postpartum hemorrhage can demonstrate the bleeding artery and is potential collaterals allowing adequate embolization without complication. (authors)

    Over the past 5 years there have been a number of new initiatives focused on improving birth outcomes and reducing infant mortality, including a renewed focus on the complex interactions between motherhood and infancy that influence lifelong health trajectories. Beginning in 2012, the Association of Maternal & Child Health Programs (AMCHP) facilitated a series of meetings to enhance coordination across initiatives. Emerging from these conversations was a shared desire across stakeholders to reimagine the postpartum visit and improve postpartum care and wellness. AMCHP convened a Postpartum Think-Tank Meeting in 2014 to map the system of postpartum care and identify levers for its transformation. The meeting findings are presented in an infographic which frames the challenges and proposed solutions from the woman's perspective. The infographic describes maternal issues and concerns along with a concise summary of the recommended solutions. Strategies include creating integrated services and seamless care transitions from preconception through postpartum and well-baby; business, community, and government support, including paid parental leave, health insurance and spaces for new parents to meet each other; and mother-centered care, including quality visits on her schedule with complete and culturally appropriate information. These solutions catalyze a postpartum system of care that supports women, children, and families by infusing new ideas and capitalizing on existing opportunities and resources.

    Modern dietary habits are characterized by high-sodium and low-potassium intakes, each of which was correlated with a higher risk for hypertension. In this study, we examined whether long-term variations in the intake of sodium and potassium induce lasting changes in the plasma concentration of circulating steroids by developing a mathematical model of steroidogenesis in mice. One finding of this model was that mice increase their plasma progesterone levels specifically in response to potassium depletion. This prediction was confirmed by measurements in both male mice and men. Further investigation showed that progesterone regulates renal potassium handling both in males and females under potassium restriction, independent of its role in reproduction. The increase in progesterone production by male mice was time dependent and correlated with decreased urinary potassium content. The progesterone-dependent ability to efficiently retain potassium was because of an RU486 (a progesterone receptor antagonist)-sensitive stimulation of the colonic hydrogen, potassium-ATPase (known as the non-gastric or hydrogen, potassium-ATPase type 2) in the kidney. Thus, in males, a specific progesterone concentration profile induced by chronic potassium restriction regulates potassium balance.

    Adenoviral vectors (vectors) expressing short-hairpin RNAs complementary to macaque nuclear progesterone (P) receptor PGR mRNA (shPGR) or a nontargeting scrambled control (shScram) were used to determine the role PGR plays in ovulation/luteinization in rhesus monkeys. Nonluteinized granulosa cells collected from monkeys (n = 4) undergoing controlled ovarian stimulation protocols were exposed to either shPGR, shScram, or no virus for 24 h; human chorionic gonadotropin (hCG) was then added to half of the wells to induce luteinization (luteinized granulosa cells [LGCs]; n = 4-6 wells/treatment/monkey). Cells/media were collected 48, 72, and 120 h postvector for evaluation of PGR mRNA and P levels. Addition of hCG increased (P < 0.05) PGR mRNA and medium P levels in controls. However, a time-dependent decline (P < 0.05) in PGR mRNA and P occurred in shPGR vector groups. Injection of shPGR, but not shScram, vector into the preovulatory follicle 20 h before hCG administration during controlled ovulation protocols prevented follicle rupture in five of six monkeys as determined by laparoscopic evaluation, with a trapped oocyte confirmed in three of four follicles of excised ovaries. Injection of shPGR also prevented the rise in serum P levels following the hCG bolus compared to shScram (P < 0.05). Nuclear PGR immunostaining was undetectable in granulosa cells from shPGR-injected follicles, compared to intense staining in shScram controls. Thus, the nuclear PGR appears to mediate P action in the dominant follicle promoting ovulation in primates. In vitro and in vivo effects of PGR knockdown in LGCs also support the hypothesis that P enhances its own synthesis in the primate corpus luteum by promoting luteinization. © 2016 by the Society for the Study of Reproduction, Inc.

    Childbirth is an important experience in a woman's life, and unfavorable birth experiences have been shown to negatively impact postpartum maternal health. Aim of this study was to evaluate the effects of music therapy on postpartum pain, anxiety level, satisfaction and early pospartum depression rate. Totally 161 primiparous women were recruited and randomized either music group (n=80) or a control group (n=81). Women in the music group listened to self-selected music during labor. Postpartum pain intensity, anxiety level and satisfaction rate were measured using the visual analog scale (VAS), postpartum depression rate was assessed with Edinburg Postpartum Depression Scale (EPDS) at postpartum day one and day eight. Mothers in the music therapy group had a lower level of postpartum pain and anxiety than the control group and it was statistically significant at all time intervals (1, 4, 8, 16 and 24h, pmusic therapy on early postpartum depression rate. Effect of music on late postpartum depression rate should be investigated in future. Using music therapy during labor decreased postpartum anxiety and pain, increased the satisfaction with childbirth and reduced early postpartum depression rate. Music therapy can be clinically recommended as an alternative, safe, easy and enjoyable nonpharmacological method for postpartum well-being. Published by Elsevier B.V.

    To date, few studies have examined suicidality in women with postpartum depression. Reports of suicidal ideation in postpartum women have varied (Lindahl et al. Arch Womens Ment Health 8:77-87, 2005), and no known studies have examined the relationship between suicidality and mother-infant interactions. This study utilizes baseline data from a multi-method evaluation of a home-based psychotherapy for women with postpartum depression and their infants to examine the phenomenon of suicidality and its relationship to maternal mood, perceptions, and mother-infant interactions. Overall, women in this clinical sample (n = 32) had wide ranging levels of suicidal thinking. When divided into low and high groups, the mothers with high suicidality experienced greater mood disturbances, cognitive distortions, and severity of postpartum symptomotology. They also had lower maternal self-esteem, more negative perceptions of the mother-infant relationship, and greater parenting stress. During observer-rated mother-infant interactions, women with high suicidality were less sensitive and responsive to their infants' cues, and their infants demonstrated less positive affect and involvement with their mothers. Implications for clinical practice and future research directions are discussed.

    Guatemala has the third highest level of maternal mortality in Latin America. Postpartum haemorrhage is the main cause of maternal mortality. In rural Guatemala, most women rely on Traditional Birth Attendants (TBAs) during labour, delivery, and the postpartum period. Little is known about current postpartum practices that may contribute to uterine involution provided by Mam- and Spanish-speaking TBAs in the Western Highlands of Guatemala. a qualitative study was conducted with 39 women who participated in five focus groups in the San Marcos Department of Guatemala. Questions regarding postpartum practices were discussed during four focus groups of TBAs and one group of auxiliary nurses. three postpartum practices believed to aid postpartum uterine involution were identified: use of the chuj (Mam) (Spanish, temazcal), a traditional wood-fired sauna-bath used by Mam-speaking women; herbal baths and teas; and administration of biomedicines. TBAs provide the majority of care to women during childbirth and the postpartum period and have developed a set of practices to prevent and treat postpartum haemorrhage. Integration of these practices may prove an effective method to reduce maternal morbidity and mortality in the Western Highlands of Guatemala. Copyright © 2011 Elsevier Ltd. All rights reserved.

    The leading cause of neonatal mortality, pre-term birth, is often caused by pre-mature ripening/opening of the uterine cervix. Although cervical fibroblasts play an important role in modulating the cervix's extracellular matrix (ECM) and mechanical properties, it is not known how hormones, i.e., progesterone, and pro-inflammatory insults alter fibroblast mechanics, fibroblast-ECM interactions and the resulting changes in tissue mechanics. Here we investigate how progesterone and a pro-inflammatory cytokine, IL-1β, alter the biomechanical properties of human cervical fibroblasts and the fibroblast-ECM interactions that govern tissue-scale mechanics. Primary human fibroblasts were isolated from non-pregnant cervix and treated with estrogen/progesterone, IL-1β or both. The resulting changes in ECM gene expression, matrix remodeling, traction force generation, cell-ECM adhesion and tissue contractility were monitored. Results indicate that IL-1β induces a significant reduction in traction force and ECM adhesion independent of pre-treatment with progesterone. These cell level effects altered tissue-scale mechanics where IL-1β inhibited the contraction of a collagen gel over 6 days. Interestingly, progesterone treatment alone did not modulate traction forces or gel contraction but did result in a dramatic increase in cell-ECM adhesion. Therefore, the protective effect of progesterone may be due to altered adhesion dynamics as opposed to altered ECM remodeling.

    Staphylococcus aureus (SA) breast abscesses are a complication of the postpartum period. Risk factors for postpartum SA breast abscesses are poorly defined, and literature is conflicting. Whether risk factors for methicillin-resistant SA (MRSA) and methicillin-susceptible SA (MSSA) infections differ is unknown. We describe novel risk factors associated with postpartum breast abscesses and the changing epidemiology of this infection. We conducted a cohort study with a nested case-control study (n = 216) involving all patients with culture-confirmed SA breast abscess among >30 000 deliveries at our academic tertiary care center from 2003 through 2010. Data were collected from hospital databases and through abstraction from medical records. All SA cases were compared with both nested controls and full cohort controls. A subanalysis was completed to determine whether risk factors for MSSA and MRSA breast abscess differ. Univariate analysis was completed using Student's t test, Wilcoxon rank-sum test, and analysis of variance, as appropriate. A multivariable stepwise logistic regression was used to determine final adjusted results for both the case-control and the cohort analyses. Fifty-four cases of culture-confirmed abscess were identified: 30 MRSA and 24 MSSA. Risk factors for postpartum SA breast abscess in multivariable analysis include in-hospital identification of a mother having difficulty breastfeeding (odds ratio, 5.00) and being a mother employed outside the home (odds ratio, 2.74). Risk factors did not differ between patients who developed MRSA and MSSA infections. MRSA is an increasingly important pathogen in postpartum women; risk factors for postpartum SA breast abscess have not changed with the advent of community-associated MRSA.

    A maximum 90-day service interval is an important economic factor in dairying. The determination of pregnancy at 21 to 26 days post-insemination can ensure that particular attention is paid to non-pregnant cows at subsequent heats, and thus help reduce this interval. In Zimbabwe a radioimmunoassay for milk progesterone using an iodinated tracer was developed in 1982 from a previously established assay for plasma progesterone. Progesterone antiserum is produced locally and the assay is used as an early pregnancy diagnosis test in dairy cattle. During 1983 two pilot schemes were instituted to investigate breed differences, logistics, and feasibility under the local conditions, and to identify constraints. Milk samples taken 24 days post-insemination were found to differentiate best between pregnant and non-pregnant cows for both major breeds in the country (Friesian/Holstein and Jersey). Pregnant cows had an average of 13.76 ng/mL (+-1.06) progesterone on day 24 while non-pregnant cows averaged 0.34 ng/mL (+-0.13) of progesterone. Apparently 12.2% of cows subsequently lost their embryos after day 24, and these cows averaged 9.98 ng/mL (+-1.52). Milk samples were also taken on the day of insemination; the results showed that 11% of cows were incorrectly inseminated when progesterone concentrations were high (2.59 ng/mL+-0.80). A National Early Pregnancy Diagnosis Scheme using milk progesterone was implemented in December 1984 and results to date are discussed in the paper. (author)

    Full Text Available Background: The relationship between breastfeeding and postpartum depression is bidirectional. Breastfeeding improves the maternal and neonatal health. There is now growing evidence that it might play a role in the prevention of postpartum depression. Objective: This study explores the relationship between breastfeeding and maternal postpartum depression. It also estimates the prevalence rate of postpartum depression among Saudi women. Methods: This is a cross-sectional study. Three-hundred postpartum women were recruited for this study from various hospitals in the Eastern Province of Saudi Arabia. Likelihood of depression was assessed using the Edinburgh Postpartum Depression Scale (EPDS. Socio-demographic data were collected as well as data regarding breastfeeding duration and intention to breastfeed. Data analysis was done using SPSS version 21, using parametric tests; independent t-test and One-Way ANOVA. Results: Postpartum mothers who intended to breast-feed their babies had a lower EPDS scores compared with those who did not intend to breast-feed. No correlation was found between the duration of breastfeeding and EPDS scores. Prevalence rate of postpartum depression in our sample was 14%. Greater age, having previous babies, intention to breastfeed and vaginal delivery were significantly associated with actual breastfeeding. Conclusion: Screening for mothers in the early postpartum period is essential to detect those who are at risk for postpartum depression. Breastfeeding may help to reduce and prevent the appearance of symptoms of depression. Prevalence rate of postpartum depression in Saudi Arabia, 14%, is similar to the worldwide rate.

    Full Text Available Background: Progesterone as a reproductive hormone is studied in the brain structure. New studies are mainly about systemic injection and have shown that the progesterone has different effects on memory. But it is not clear if hippocampus is mediator of progesterone in reinforcement of memory and learning. So, the effects of intra-hippocampal injection of progesterone on passive avoidance memory and learning was studied in male Wistar rats. Material and Methods: Animals were divided in eightgroups as a control, saline, almond oil (as a vehicle and progesterone groups (0.5, 1, 1.5, 2, 3µg/Kg. body weight. All groups except the control were cannulated in left CA1 area by stereotaxic device. One week after recovery, all groups were trained by shuttle box and immediately after training different doses of progesterone in the volume of 0.5μL were injected through the cannula in CA1 of hippocampus and control groups received saline and almond oil at the same volume and condition respectively. After 48 hours passive avoidance memory and learning was evaluated. Results: Statistical analysis showed that 0.5, 1.5, 2 µg/µl progesterone groups had significantly improved passive avoidance learning and memory compared with saline group (p <0.001, but 1 and 3 µg/µl progesterone groups did not show significant effect on passive avoidance learning and memory compared with saline group. Also almond oil increased passive avoidance learning and memory compared with saline group (p <0.001. Conclusion: It seems that effects of progesterone as a neurosteroid on memory and learning depend on its dose. Also almond oil contains vitamin E, omega 3 and oleic acid that has beneficial effects on learning and memory.

    Mothers (n = 92), fathers (n = 84), and their infants (60% male) participated in a longitudinal study of postpartum depression and maternal sensitivity. Mothers completed questionnaire measures of remembered parental acceptance, depressive symptoms, and infant distress to novelty and limits. Mothers and partners reported on marital aggression and avoidance. Maternal sensitivity was observed in the laboratory at 6 months. Characteristics of mothers, partners, and infants combined to predict postpartum depression and maternal sensitivity. Remembered parental rejection predicted postpartum depressive symptoms with prenatal depression controlled; self-esteem mediated this effect. Paternal acceptance buffered against postpartum depression when infants were highly reactive and when partners were aggressive. Paternal acceptance reduced the impact of postpartum depression on maternal sensitivity; having an aggressive marital partner exacerbated the effect.

    Colour Doppler ultrasonography was used to compare the ability of preovulatory follicle (POF) blood flow and its dimensions to predict the size, blood flow and progesterone production capability of the subsequent corpus luteum (CL). Cows (n=30) were submitted to a synchronisation protocol. Follicles ≥7mm were measured and follicular wall blood flow evaluated every 12h for approximately 3.5 days until ovulation. After ovulation, cows were scanned daily for 8 days and similar parameters were evaluated for the CL. Blood samples were collected and plasma progesterone concentrations quantified. All parameters were positively correlated. Correlation values ranged from 0.26 to 0.74 on data normalised to ovulation and from 0.31 to 0.74 on data normalised to maximum values. Correlations between calculated ratios of both POF and CL in data normalised to ovulation and to maximum values ranged from moderate (0.57) to strong (0.87). Significant (Pprogesterone concentrations of the resultant CL. These findings indicate that follicle vascularity coordinates CL blood flow and progesterone production in synchronised beef cows.

    More than one quarter of human world's population is exposed to intestinal helminth parasites. The Taenia solium tapeworm carrier is the main risk factor in the transmission of both human neurocysticercosis and porcine cysticercosis. Sex steroids play an important role during T. solium infection, particularly progesterone has been proposed as a key immunomodulatory hormone involved in susceptibility to human taeniosis in woman and cysticercosis in pregnant pigs. Thus, we evaluated the effect of progesterone administration upon the experimental taeniosis in golden hamsters (Mesocricetus auratus). Intact female adult hamsters were randomly divided into 3 groups: progesterone-subcutaneously treated; olive oil-treated as the vehicle group; and untreated controls. Animals were treated every other day during 4 weeks. After 2 weeks of treatment, all hamsters were orally infected with 4 viable T. solium cysticerci. After 2 weeks post infection, progesterone-treated hamsters showed reduction in adult worm recovery by 80%, compared to both vehicle-treated and non-manipulated infected animals. In contrast to control and vehicle groups, progesterone treatment diminished tapeworm length by 75% and increased proliferation rate of leukocytes from spleen and mesenteric lymph nodes of infected hamsters by 5-fold. The latter exhibited high expression levels of IL-4, IL-6 and TNF-α at the duodenal mucosa, accompanied with polymorphonuclear leukocytes infiltration. These results support that progesterone protects hamsters from the T. solium adult tapeworm establishment by improving the intestinal mucosal immunity, suggesting a potential use of analogues of this hormone as novel inductors of the gut immune response against intestinal helminth infections and probably other bowel-related disorders.

    Postpartum depression affects a huge number of women and has detrimental consequences. Knowing the factors associated with postpartum depression during pregnancy can help its prevention. Although there is evidence surrounding behavioral or psychological predictors of postpartum depression, there is a lack of evidence of biological forecasters. The aim of this study was to analyze the sociodemographic, obstetric, and psychological variables along with hair cortisol levels during the first, second, and third trimesters of pregnancy that could predict postpartum depression symptoms. A sample of 44 pregnant women was assessed during 3 trimesters of pregnancy and the postpartum period using psychological questionnaires and hair cortisol levels. Participants were divided into 2 groups: a group with postpartum depression symptoms and a group with no postpartum depression symptoms. Results showed significant positive differences between groups in the first trimester regarding the Somatization subscale of the SCL-90-R (p Depression, Anxiety, and GSI subscales (p postpartum depression symptoms. In conclusion, our study provided evidence that psychopathological symptoms, pregnancy-specific stress, and hair cortisol levels can predict postpartum depression symptoms at different time-points during pregnancy. These findings can be applied in future studies and improve maternal care in clinical settings.

    2018-04-01

    In the present study, we aimed to examine effects of different concentrations of the endocrine disruptor Bisphenol A (BPA; 1 nM, 1 μM, 100 μM) and the flavonoid fisetin (1, 10, 25, 50 μM), individually and in combinations, on steroidogenic function of porcine ovarian granulosa cells (GCs) represented by progesterone production. We confirmed that BPA inhibited progesterone production by GCs at the highest concentration. Fisetin reduced gonadotropin-stimulated progesterone synthesis dose-dependently, and in this manner, fisetin impaired progesterone production when added to BPA-treated GCs. The mechanisms of the inhibitory effects of the combinations included a significant down-regulation of the key steroidogenesis-related genes (STAR, CYP11A1, HSD3B). Our findings suggest for the first time that fisetin might interfere with ovarian steroidogenesis, and might not have beneficial but rather aggravating effects in terms of modulating progesterone synthesis altered by high concentrations of BPA.

    A survey was carried out to evaluate the reproductive performance of crossbred zebu cattle under artificial insemination (AI). Defatted milk samples were taken for progesterone radioimmunoassay at the moment of AI (day 0), 10 days and 22 days after AI and at manual pregnancy diagnosis. Six farms located in the western region of Venezuela were used in this study and a total of 600 AI were included. The calving to first service interval (CFSI) and the calving to conception interval (CCI) showed no significant differences between the hand milking (suckling) and machine milking (non suckling) systems. However, significant differences (P<0.05) were found among farms within the traditional and hand milking system. The mean (± SEM) CFSI for first calving heifers and for cows with second or higher parity was 141.9 ± 6.9 and 71.8 ± 4.2 days (P<0.05), and the CCI for these two groups was 154 ± 8.9 and 80.8 ± 5.5 days (P<0.05), respectively. Cows calving in the dry season had CFSI and CCI of 115.4 ± 5.2 and 123.8 ± 6.8 days, while for those calving in the rainy season the intervals were 98.3 ± 5.5 and 111.1 ± 7.2 days respectively (P<0.05). Predominantly Bos indicus cows had shorter CFSI and CCI (P<0.05) than predominantly Bos taurus cows. Overall conception rate, analyzed by Chi-square, showed significant differences due to predominant breed and parity. Correct heat detection, as determined by low progesterone levels at AI, was 95.5% in the best farm and 83.3% in the worst farm. The results of this study identify a postpartum anoestrus problem, especially in the first calf heifers with an important effect of season, breed, farm, and heat detection on the reproductive efficiency of farms under AI. After this survey a study was carried out to evaluate the effectiveness of calf removal for 96 hours compared with treatment using norgestomet implants and PMSG for oestrus induction and fertility in crossbred primiparous acyclic zebu. cows which were suckled twice a day

    Progesterone concentration in the peripheral blood plasma of ten lactating goats of mixed breeds following breeding were determined by radioimmunoassay to diagnose early pregnancy. The mean concentration was very low (0.25 +- 0.15 ng/ml) on the day of oestrus and reached at peak level on day 13 (1.30 +- 0.07 ng/ml) and on day 19 (2.77 +- 1.18 ng/ml) in non-pregnant and pregnant goats, respectively. The level sharply declined on day 19 (0.40 +- 0.07 ng/ml) of oestrous cycle in non-pregnant goats. However, the level remained below 1.5 ng/ml on day 9, 13, 15 and 17 and 3 ng/ml on day 9, 13, 15, 17, 19, 21 and 23 in nonpregnant and pregnant goats, respectively. The progesterone concentration continued to increase to 2.94 +- 0.70, 4.42 +- 0.92 and 6.2 +- 0.61 ng/ml on day 45, 60 and 75 of gestation, respectively. (auth.)

    Full Text Available Abstract Background Women's evaluation of hospital postpartum care has consistently been more negative than their assessment of other types of maternity care. The need to further explore what is wrong with postpartum care, in order to stimulate changes and improvements, has been stressed. The principal aim of this study was to describe women's negative experiences of hospital postpartum care, expressed in their own words. Characteristics of the women who spontaneously gave negative comments about postpartum care were compared with those who did not. Methods Data were taken from a population-based prospective longitudinal study of 2783 Swedish-speaking women surveyed at three time points: in early pregnancy, at two months, and at one year postpartum. At the end of the two follow-up questionnaires, women were asked to add any comment they wished. Content analysis of their statements was performed. Results Altogether 150 women gave negative comments about postpartum care, and this sample was largely representative of the total population-based cohort. The women gave a diverse and detailed description of their experiences, for instance about lack of opportunity to rest and recover, difficulty in getting individualised information and breastfeeding support, and appropriate symptom management. The different statements were summarised in six categories: organisation and environment, staff attitudes and behaviour, breastfeeding support, information, the role of the father and attention to the mother. Conclusion The findings of this study underline the need to further discuss and specify the aims of postpartum care. The challenge of providing high-quality follow-up after childbirth is discussed in the light of a development characterised by a continuous reduction in the length of hospital stay, in combination with increasing public demands for information and individualised care.

    The urinary incontinence can affect up to 50% of women at some stage of their lives, particularly during pregnancy and postpartum. This study was designed in order to identify and assess the prevalence and risk factors for urinary incontinence during the third trimester of pregnancy and three months postpartum. Observational and cross-sectional study. The population of the study was composed of 268 women who delivered and were admitted to the Centro Hospitalar Tâmega e Sousa in the years 2013 and 2014, and who agreed to participate in this study. Postpartum women were asked to fill out a questionnaire adapted from the International Consultation on Incontinence Questionnaire - Short Form, for urinary incontinence research in the third trimester of pregnancy. Three months after delivery, they were contacted by telephone and asked to answer the same questions about the urinary incontinence postpartum. Of the 268 women interviewed, 31 were excluded from the study, taking into account the defined inclusion and exclusion criteria. In total (n = 237), 51.89% of women included in the study, reported the occurrence of urinary incontinence during pregnancy. The prevalence of urinary incontinence in pregnancy by parity (primiparous versus multiparous) was statistically significant (p = 0.006). At postpartum (n = 237), 28.69% of women with urinary incontinence had vaginal delivery and 5.91% of women underwent cesarean delivery (p = 0.001). In these group of women with postpartum urinary incontinence (n = 82), 31.69% have had urinary incontinence only in the postpartum and 68.31% of women have had symptoms during pregnancy (p urinary incontinence in pregnancy and the respective decrease in postpartum. Multiparity and occurrence of urinary incontinence in pregnancy appear as potential risk factors in the emergence of the urinary incontinence.

    The main message of this work is the fact that female sex hormones, progesterone and estradiol, whose levels significantly rise during pregnancy, inhibit the production of anti-inflammatory cytokine IL-10 with no apparent effect on pro-inflammatory cytokine TNF-α by activated MZ B cells. This is an important piece of information and helps to better understand how the maternal immune system controls the balance between immune tolerance and immune activation during pregnancy leading to the simultaneously acceptance of the semi-allogeneic fetus and the proper defense of the mother against pathogens during this critical period of time.

    Postpartum depression can have devastating consequences on the mother and child. Prompt treatment is challenging. Whereas electroconvulsive therapy (ECT) is considered to be an effective treatment modality in severe depression and brings about rapid clinical improvement, little is known about ECT during the postpartum period. We systematically reviewed the literature on the use of ECT during the postpartum period using PubMed, Institute for Scientific Information Web of Knowledge and PsycINFO databases until September 2014, using the search terms "electroconvulsive therapy" or "ECT" and "postpartum". Then, we described the successful treatment with ECT and the joint mother-baby hospitalization of a woman with severe depression. Eight case reports and 8 studies were identified. All of the studies reported that ECT is effective in the postpartum period. It is well tolerated, provides a fast response and allows for breastfeeding. In addition, our case report showed the benefits of the hospitalization of the mother-baby unit. Combined ECT and joint mother-baby hospitalization could be a valuable treatment by targeting both the mother-infant relationship and the maternal depressive symptoms. Copyright © 2015 Elsevier Inc.

    The postpartum period is when a host of changes occur at molecular, cellular, physiological and behavioral levels to prepare female humans for the challenge of maternity. Alteration or prevention of these normal adaptions is thought to contribute to disruptions of emotion regulation, motivation and cognitive abilities that underlie postpartum mental disorders, such as postpartum depression. Despite the high incidence of this disorder, and the detrimental consequences for both mother and child, its etiology and related neurobiological mechanisms remain poorly understood, partially due to the lack of appropriate animal models. In recent decades, there have been a number of attempts to model postpartum depression disorder in rats. In the present review, we first describe clinical symptoms of postpartum depression and discuss known risk factors, including both genetic and environmental factors. Thereafter, we discuss various rat models that have been developed to capture various aspects of this disorder and knowledge gained from such attempts. In doing so, we focus on the theories behind each attempt and the methods used to achieve their goals. Finally, we point out several understudied areas in this field and make suggestions for future directions. PMID:27469254

    Data from 96 Holstein Friesian cows on a commercial dairy farm were used to investigate whether body condition and serum levels of nonesterified fatty acids (NEFAs) postpartum (pp) affect progesterone (P4) levels, estrous activity, and fertility in dairy cows. The examination period started 14 days before the expected calving date and ended either when a cow was inseminated or at a maximum of 90 days pp. Body condition score (BCS; 1-5 scale) and backfat thickness (BFT) were determined every 2 weeks. Blood for analysis of NEFA and P4 concentrations was sampled weekly during the first 35 days pp and then every 48 hours until an ovulation was observed. Transrectal ultrasonography of the ovaries started at 21 days pp and was performed after blood sampling. If cows were not inseminated because of silent ovulation, sampling and ultrasonography continued on Days 7, 14, and 18 after ovulation and again every 48 hours until the next ovulation. Estrous activity was continuously measured with the Heatime estrus detection system. Pregnancy controls were performed ultrasonographically 28 and 42 days after AI. Cows with increased NEFA levels at 28 days pp had an increased risk of maintaining minimum P4 levels above 0.4 ng/mL at first recognized estrus (P = 0.03). Higher NEFA levels at Day 7 were associated with lower probability for a cow to have elevated P4 levels (≥2 ng/mL) by Day 35 pp, indicating delayed commencement of luteal activity (C-LA). Estrous activity was not influenced (P > 0.10) by minimum P4 concentrations at estrus, but more animals with C-LA until Day 35 pp showed estrous activity compared to cows without C-LA throughout this period (P = 0.006). Estrous activity was lower in cows with a low BCS 14 days pp (P = 0.02) and with a low BFT 42 days pp (P = 0.03). Moreover, the probability to exhibit estrus was reduced with higher NEFA levels at 21 days pp (P = 0.01). Eighty-five cows were inseminated and 37 (44%) got pregnant after insemination. Higher NEFA levels

    OBJECTIVE: We studied the influence of maternal behavior on weight change from prepregnancy to 7 years postpartum. METHODS: We used linear regression to study the independent and combined associations between self-reported behavior in pregnancy (dietary intake, leisure-time exercise, sedentary...... activity, smoking) and postpartum (breastfeeding duration and smoking) on weights at 6 months, 18 months, and 7 years postpartum. RESULTS: Women's average 7-year weight gain was 2.07 kg, with 23% gaining >5 kg. Multivariable analyses suggested that women with healthier dietary intake, more leisure......-time exercise, less sedentary behavior, and longer duration of breastfeeding on average gained 1.66 kg [95% confidence interval (CI): 1.40; 1.91] with a significantly reduced odds [OR 0.56 (95% CI: 0.49; 0.64)] of gaining >5 kg from prepregnancy to 7 years postpartum compared to women with none or one...

    2009-08-01

    The number of incarcerated women in the United States is steadily increasing with 9% giving birth while serving time. Mothers and babies are routinely separated immediately and during most of the postpartum period. This qualitative study examines the impact of this policy by exploring the nature and meaning of the mother-infant bonding experience when the mothers know separation is coming. Twelve incarcerated postpartum mothers were interviewed during the early postpartum period about their antepartum and postpartum relationships with their babies. Qualitative data analysis produced four relational themes: (a) "a love connection," (b) "everything was great until I birthed," (c) "feeling empty and missing a part of me," and (d) "I don't try to think too far in advance." Results of this qualitative study provide information to professionals exploring gender-sensitive prison policies for the growing female population.

    Full Text Available Background: Postpartum home care plays an important role in prevention of postpartum complications. Regular visits of mothers during this period are imperative. This study aimed to provide postpartum home care for mothers to assess its effects on mothers' health in Iran. Materials and Methods: This study was carried out in two phases. First, a comprehensive postpartum home care program was compiled by performing a comparative study, using the available guidelines in this regard in different countries and based on the opinions of the experts. Next, a clinical trial was carried out on 276 women who gave birth in the university hospitals affiliated to Shahid Beheshti University of Medical Sciences. There were 92 mothers in the intervention and 184 in the control group. The intervention group mothers were provided with postpartum home care service while the control group did not receive such a service. Results: Outcome assessment at 60 days' postpartum revealed a significant difference between the two groups in terms of the use of supplements, birth control methods, postpartum depression, breastfeeding problems, constipation, and fatigue (P 0.05. Conclusion: The postpartum home care program had a positive effect on some aspects of the mothers' health status and their satisfaction in our society.

    Full Text Available Abstract OBJECTIVE: To investigate the risk factors for postpartum urinary incontinence (UI and its characteristics. METHOD: This was a case-control study with 344 puerperal women (77 cases and 267 controls with up to 90 days postpartum. In a single session, participants were given a questionnaire with sociodemographic and clinical data and two others that assessed urine leakage, leakage situations, and type of UI. RESULTS: Stress UI was present in 45.5% of the women, incidents of urine leakage several times a day in 44.2%, of which 71.4% were in small amounts and 57.1% when coughing or sneezing. In 70.1% of cases, UI began during pregnancy and remained through the postpartum period. After running a binary logistic regression model, the following factors remained in the final model: UI during pregnancy (OR 12.82, CI 95% 6.94 - 23.81, p<0.0001, multiparity (OR 2.26, CI 95% 1.22 - 4.19, p=0.009, gestational age at birth greater or equal to 37 weeks (OR 2.52, CI 95% 1.16 - 5.46, p=0.02 and constipation (OR 1.94, CI 95% 1.05 - 5.46, p=0.035. CONCLUSION: Most often, UI first appeared during pregnancy and remained through the postpartum period. Urinary incontinence during pregnancy, multiparity, gestational age at birth greater or equal to 37 weeks, and constipation were presented as risk factors. In the studied group, stress UI was more frequent.

    Fluctuations in progesterone levels during the menstrual cycle have been shown to affect physiological and subjective effects of cocaine. Furthermore, our laboratory has demonstrated that following drug-cue exposure, cocaine dependent women with high levels of circulating progesterone display lower diastolic and systolic blood pressure responses and report lower levels of anxiety and drug craving compared to cocaine dependent women with low levels of progesterone. In the current study we examined the role of the progesterone derived neuroactive steroid allopregnanolone (ALLO) on stress arousal, inhibitory control and drug craving in cocaine dependent subjects. Plasma levels of ALLO were measured using GC/MS in 46 treatment-seeking cocaine dependent men and women on day 5 of a 7-day treatment regimen of micronized progesterone (15M/8F) (400mg/day) or placebo (14M/9F) administered in a double blind, randomized manner. As a control, levels of the testosterone derived neurosteroid androstanediol (ADIOL) were also measured. All subjects participated in laboratory sessions on days 5-7 of progesterone/placebo administration in which they were exposed to a series of 5-min personalized guided imagery of either a stressful situation, cocaine use or of a neutral setting and dependent variables including subjective craving, mood, Stroop task as a measure of inhibitory control performance and plasma cortisol were assessed. Participants were grouped by high or low ALLO level and levels of dependent variables compared between ALLO groups. Progesterone relative to placebo significantly increased ALLO levels with no sex differences. There were no effects of micronized progesterone on the testosterone derived ADIOL. Individuals in the high versus the low ALLO group showed decreased levels of cortisol at baseline, and a higher cortisol response to stress; higher positive mood scores at baseline and improved Stroop performance in the drug-cue and stress conditions, and reduced cocaine

    Arsenic contamination is a principal environmental health threat throughout the world. However, little is known about the effect of arsenic on steroidogenesis in granulosa cells (GCs). We found that the treatment of preovulatory GCs with arsenite stimulated progesterone production. A significant increase in serum level of progesterone was observed in female Sprague-Dawley rats following arsenite treatment at a dose of 10 mg/L/rat/day for 7 days. Further experiments demonstrated that arsenite treatment did not change the level of intracellular cyclic AMP (cAMP) or phosphorylated ERK1/2 in preovulatory GCs; however, progesterone production was significantly decreased when cAMP-dependent protein kinase (PKA) or ERK1/2 pathway was inhibited. This implied that the effect of arsenite on progesterone production may require cAMP/PKA and ERK1/2 signaling but not depend on them. Furthermore, we found that arsenite decreased intracellular reactive oxygen species (ROS) but increased the antioxidant glutathione (GSH) levels and mitochondrial membrane potential (ΔΨm) in parallel to the changes in progesterone production. Progesterone antagonist blocked the arsenic-stimulated increase of GSH levels. Arsenite treatment induced caspase-3 activation, although no apoptosis was observed. Inhibition of caspase-3 activity significantly decreased progesterone production stimulated by arsenite or follicle-stimulating hormone (FSH). GSH depletion with buthionine sulfoximine led to cell apoptosis in response to arsenite treatment. Collectively, this study demonstrated for the first time that arsenite stimulates progesterone production through cleaved/active caspase-3-dependent pathway, and the increase of GSH level promoted by progesterone production may protect GCs against apoptosis and maintain the steroidogenesis of GCs in response to arsenite treatment.

    A growing number of women are seeking alternatives to traditional pharmacologic pain management during birth. While there has been an extensive array of nonpharmacologic options developed for labor, there are limited offerings in the postpartum period. The purpose of this quality improvement project was to implement a hydrotherapy protocol in the early postpartum period to improve pain management for women choosing a nonmedicated birth. The postpartum hydrotherapy protocol was initiated in a certified nurse-midwife (CNM) practice in an urban academic medical center. All women who met criteria were offered a 30-minute warm water immersion bath at one hour postpartum. Pain scores were assessed prior to the bath, at 15 minutes after onset, and again at the conclusion (30 minutes). Women who completed the bath were also asked to complete a brief survey on their experience with postpartum hydrotherapy. In women who used the bath (N = 45), there was a significant reduction in pain scores (P hydrotherapy protocol as an alternative or adjunct to medication for early postpartum pain management that significantly reduced pain and improved the birth experience for those who used it. It offers a nonpharmacologic alternative where there have traditionally been limited options. © 2017 by the American College of Nurse-Midwives.

    Full Text Available Becoming a mother is a time of transition, transformation and sometimes trauma. The immediacy of meeting the needs of an infant, combined with the immediacy of becoming a mother, often collide to produce depression, anxiety and stress. Shame, confusion, isolation and cultural expectations often prevent women from seeking the postpartum support they need, which may result in long lasting depression, anxiety and unresolved trauma. Integrative Psychotherapy, Transactional Analysis and Attachment Theory offer ways to understand postpartum adjustment as well as methodologies for addressing this unique developmental event in the life of women.

  18. COUP-TFII mediates progesterone regulation of uterine implantation by controlling ER activity.

    Full Text Available Progesterone and estrogen are critical regulators of uterine receptivity. To facilitate uterine remodeling for embryo attachment, estrogen activity in the uterine epithelia is attenuated by progesterone; however, the molecular mechanism by which this occurs is poorly defined. COUP-TFII (chicken ovalbumin upstream promoter transcription factor II; also known as NR2F2, a member of the nuclear receptor superfamily, is highly expressed in the uterine stroma and its expression is regulated by the progesterone-Indian hedgehog-Patched signaling axis that emanates from the epithelium. To further assess COUP-TFII uterine function, a conditional COUP-TFII knockout mouse was generated. This mutant mouse is infertile due to implantation failure, in which both embryo attachment and uterine decidualization are impaired. Using this animal model, we have identified a novel genetic pathway in which BMP2 lies downstream of COUP-TFII. Epithelial progesterone-induced Indian hedgehog regulates stromal COUP-TFII, which in turn controls BMP2 to allow decidualization to manifest in vivo. Interestingly, enhanced epithelial estrogen activity, which impedes maturation of the receptive uterus, was clearly observed in the absence of stromal-derived COUP-TFII. This finding is consistent with the notion that progesterone exerts its control of implantation through uterine epithelial-stromal cross-talk and reveals that stromal-derived COUP-TFII is an essential mediator of this complex cross-communication pathway. This finding also provides a new signaling paradigm for steroid hormone regulation in female reproductive biology, with attendant implications for furthering our understanding of the molecular mechanisms that underlie dysregulation of hormonal signaling in such human reproductive disorders as endometriosis and endometrial cancer.

    Full Text Available Alternative methods to the utilization of laboratory animal blood and its by-products are particularly attractive, especially regarding hamsters due to their small size and difficulties in obtaining serial blood samples. Steroid hormone metabolite quantification in feces, widely used in studies of free-ranging or intractable animals, is a non-invasive, non-stressor, economical, and animal saving technique which allows longitudinal studies by permitting frequent sampling of the same individual. The present study was undertaken to determine the suitability of this method for laboratory animals. Estradiol and progesterone metabolites were quantified by radioimmunoassay in feces of intact, sexually mature female Syrian hamsters during the estrous cycle (control and in feces of superovulated females. Metabolites were extracted by fecal dilution in ethanol and quantified by solid phase radioimmunoassay. Median estrogen and progesterone concentrations were 9.703 and 180.74 ng/g feces in the control group, respectively. Peaks of estrogen (22.44 ± 4.54 ng/g feces and progesterone (655.95 ± 129.93 ng/g feces mean fecal concentrations respectively occurred 12 h before and immediately after ovulation, which is easily detected in this species by observation of a characteristic vaginal postovulatory discharge. Median estrogen and progesterone concentrations (28.159 and 586.57 ng/g feces, respectively were significantly higher in superovulated animal feces (P < 0.0001. The present study demonstrated that it is possible to monitor ovarian activity in Syrian hamsters non-invasively by measuring fecal estradiol and progesterone metabolites. This technique appears to be a quite encouraging method for the development of new endocrinologic studies on laboratory animals.

    To examine mothers' postpartum perceptions of stress and satisfaction. Methodologic triangulation with quantitative and qualitative data in a nonexperimental design. A convenience sample of 95 women was obtained during normally scheduled postpartum appointments at a health maintenance organization. The self-administered questionnaire included the Mothers' Information Tool (MIT), What Being the Parent of a Baby Is Like (WPL-R), and the Brief Symptom Inventory (BSI). Open-ended MIT items revealed mothers' perceptions of stress and satisfaction. The WPL-R provided maternal satisfaction scores, and the BSI yielded Global Stress Index scores. Content analysis identified the following categories: Roles, Tasks, Resources, and Relationships. Subcategories identified as areas of stress were Work/School, Sleep/Rest, Adjustment/Own Needs, Health/Body Image, Organization of Life, Child Care, Day Care, Housework, Future Challenges, Finances, Housing, Time, Partner, and Family. Subcategories identified as areas of satisfaction were Participating in Relationships, Sharing the Future, Being Proud to Be a Mother, Enjoying a Healthy Baby, and Caring for a Child. Levels of stress and satisfaction of mothers who scored high and low on quantitative measures were compared. The outcomes contribute to the knowledge concerning postpartum women's perceptions of the mothering experience and suggest approaches to nursing assessment and intervention to prevent postpartum adjustment difficulties.

    Pregnancy may contribute to overweight and obesity. The primary objective of Active Mothers Postpartum was to promote a reduction in BMI through 24-months postpartum via sustainable lifestyle changes. Behavioral intervention RCT to enhance postpartum weight loss. A total of 450 overweight or obese women, enrolled 6-weeks postpartum, were recruited through obstetrics clinics and community posters in the Durham NC area. Intervention participants were offered eight healthy-eating classes, ten physical-activity classes, and six telephone-counseling sessions over 9 months. Changes from baseline (6-weeks postpartum) to 1-month post-intervention (12-months postpartum) in: (1) diet (caloric intake, calories from fat, intake of certain foods); (2) physical activity (self-reported physical activity, television time); and (3) weight (collected 2004-2007, analyzed 2007-2008). Mean weight loss was 0.90 kg (+/-5.1 kg) in the intervention group and 0.36 kg (+/-4.9 kg) in the control group; this difference was not significant. There were also no significant group differences in improvement of diet or increased physical activity. In secondary analyses, there was a positive bivariate relationship between classes attended and weight loss (p=0.01). There were no significant differences among the arms in diet, physical activity, or weight change. Home-based interventions via mail, telephone, or Internet/e-mail may be more feasible and successful in this population. The postpartum period is an important phase in women's lives with regard to weight retention, but engaging them during this busy period remains a challenge. NCT00212251.

    Postpartum bladder rupture is an uncommon surgical emergency and a diagnostic challenge. A primigravida delivered a healthy newborn without complications at 39.4 weeks of gestation. The patient was admitted 80 hours postpartum with abdominal pain, oliguria, hematuria, and pain that worsened during the previous 4 hours. An inserted Foley catheter drained only a small amount of urine, and serum creatinine was elevated (3.5 mg/dL). A laparotomy was performed and revealed a 10-cm hole in the urinary bladder. The bladder was repaired and the patient was discharged 15 days after surgery. The follow-up cystoscopy revealed adequate healing of the bladder. Urinary retention can lead to serious complications, including bladder rupture. Postpartum bladder rupture due to urinary retention should be ruled out if there is a history of abdominal pain, oliguria, and elevated of serum creatinine.

    Little is known about the recovery of the immune system from normal pregnancy and whether the postpartum period is a uniquely adapted immune state. This report extends previous observations from our group of decreased natural killer (NK) cell cytotoxicity in the postpartum period. NK cytotoxicity was measured from 1 week through 9 months postpartum. In addition, NK cytotoxicity was assayed in the presence or absence of pooled plasmas collected from either postpartum or nonpostpartum women. Samples of cells were stained for inhibitory receptors and analyzed by flow cytometry. NK cytotoxicity remained decreased in postpartum women compared to controls through the first 6 postpartum months, returned to normal levels by 9 months, and remained normal at 12 months. NK cytotoxicity during the first 6 months was further inhibited by the addition of pooled plasma to NK cultures from postpartum women, but the addition of pooled plasma from the control group did not affect that group's NK cultures. There were differences in inhibitory receptor staining between the two groups, with decreased CD158a and CD158b and increased NKG2A expression on postpartum NK cells during the first 3 postpartum months. These data suggest that NK cytotoxicity postpartum inhibition lasts 6 months and is influenced by unidentified postpartum plasma components. The effect may also involve receptors on NK cells. © The Author(s) 2013.

    Full Text Available Introduction: Alzheimer’s disease is one of the most prevalent brain neurodegenerative diseases and the most common cognitive deficits are memory dysfunction and spatial perception impairment. Progesterone has a neorostroid action in hippocampal neurogenesis, synaptic stability and spatial learning and memory and has antioxidant effect. Since oxidative stress is involved in the pathogenesis of Alzheimer's disease, and conflicting results were reported about the effects of progesterone on therefore in Alzheimer’s, the present study investigated the effect of microinjection of three doses of progesterone on the process of spatial memory and lipid peroxidation and total peroxidation in the hippocampus in the experimental model of AD. Methods: 42 adult male Wistar rats weighting 250±50 g were randomly divided into six main groups (n=7: control group, sham group, Alzheimer’s model (intracerebroventricular injection of streptozotocin, Alzheimer model + progesterone (0.5, 1.5, 2µg/kg. 2 weeks after injection of streptozotocin (3 mg/kg, Alzheimer's was induced then progesterone injected in different doses. After termination of behavioral testing days, the hippocampus was removed to measure the levels of oxidative stress parameter to measure levels of oxidative stress parameters. Statistical analysis was performed using analysis of variance (ANOVA. Results: Results showed that intraventricular injection of STZ decreased spatial memory in comparison to control group (P<0.001. Administration progesterone significantly improved spatial memory in experimental models of Alzheimer's rats (P<0.001. MDA and SOD in all doses of progesterone showed a significant reduction compared to the AD animals (P<0.001. Conclusion: Progesterone can prevent a decrease in spatial learning and memory by reducing oxidative stress in the hippocampus of rats with Alzheimer's.

    This study was undertaken to provide information on diagnosis of cyclicity, confirmation of estrus so that mating timing and confirmation of return on non-return (pregnancy diagnosis) in Angora goats by using progesterone radioimmunoassay (RIA) in serum as well as observing the sexual behaviours of the goats. The cyclic reproductive activity of 20 mature Angora goat does with normal previous reproductive function, 5 does which had never become pregnant in the previous breeding seasons, and 10 does which were old for breeding was investigated. Circulating progesterone was relatively low (0.45 ng/ml) at estrus (day 0) and increased progressively to 3.45 ng/ml during the subsequent luteal phase. This high level was maintained until day-3 of the succeding estrus cycle, when it decreased abruptly. Pregnancy diagnosis based on the levels of progesterone in serum was confirmed by kidding. 1.5 ng/ml or more progesterone was used as an indication of pregnancy (within 21 days after mating). The accuracy of pregnancy by progesterone assay was 100%. It was concluded that the use of progesterone RIA in serum is a reliable and convenient means of monitoring ovarian activity and early pregnancy. (author)

    Full Text Available Ureaplasma parvum (U. parvum is gaining recognition as an important pathogen for chorioamnionitis and preterm premature rupture of membranes. We aimed to investigate the roles of progesterone (P4 and a novel progesterone receptor, progesterone receptor membrane component 1 (PGRMC1, in the response of fetal membranes to U. parvum. Fetal membrane cells (amnion, chorion and decidua were isolated and confirmed to be free of Mycoplasmataceae. Cells were treated with U. parvum (5x106 CFU, and adherence was quantified by qPCR. Amnion and chorion cells were transfected with scrambled siRNA or validated PGRMC1 siRNA for 72h. Cells were then treated with U. parvum for 4h with or without pretreatment with P4 (10-7 M or ethanol for 1h. Interleukin-8 (IL-8, matrix metalloproteinase 9 (MMP9 and cyclooxygenase (COX-2 mRNA expression were quantified by qRT-PCR. Culture medium was harvested and analyzed for IL-8 and prostaglandin (PGE2 secretion by ELISA and MMP9 activity by zymography. U. parvum had a mean adherence of 15.0±0.6%, 16.9± 3.7% and 4.7±0.3% in cultured amnion, chorion and decidua cells, respectively. Exposure to U. parvum elicited significant inflammatory responses including induction of IL-8, COX-2, PGE2 and MMP9. A possible role of PGRMC1 was identified in the inhibition of U. parvum-stimulated COX-2 and MMP9 mRNA expression in chorion cells and MMP9 activity in amnion cells. On the other hand, it might enhance the U. parvum-stimulated IL-8 protein secretion in amnion cells. P4, mediated through PGRMC1, significantly inhibited U. Parvum-induced MMP9 mRNA and COX-2 mRNA expression in chorion cells. P4 appeared to attenuate U. parvum induced IL-8 mRNA expression in chorion cells, but this P4 effect might not mediated through PGRMC1. In summary, U. parvum preferentially adheres to and induces inflammatory responses in chorion and amnion cells. P4 and PGRMC1 appear to differentially modulate the inflammatory responses induced by U. parvum among

    To estimate, from the literature, when nonlactating postpartum women regain fertility. We searched PubMed and Cochrane Library databases for all articles (in all languages) published in peer-reviewed journals from database inception through May 2010 for evidence related to the return of ovulation and menses in nonlactating postpartum women. Search terms included "Fertility" (Mesh) OR "Ovulation" (Mesh) OR "Ovulation Detection" (Mesh) OR "Ovulation Prediction" (Mesh) OR fertility OR ovulat* AND "Postpartum Period" (Mesh) OR postpartum OR puerperium AND Human AND Female. We included articles assessing nonlactating women's first ovulation postpartum. Studies in which women breastfed for any period of time or in whom lactation was suppressed with medications were excluded. We identified 1,623 articles; six articles reported four studies met our inclusion criteria. In three studies utilizing urinary pregnanediol levels to measure ovulation, mean day of first ovulation ranged from 45 to 94 days postpartum; 20%-71% of first menses were preceded by ovulation and 0%-60% of these ovulations were potentially fertile. In one study that used basal body temperature to measure ovulation, mean first ovulation occurred on day 74 postpartum; 33% of first menses were preceded by ovulation and 70% of these were potentially fertile. Most nonlactating women will not ovulate until 6 weeks postpartum. A small number of women will ovulate earlier, potentially putting them at risk for pregnancy sooner, although the fertility of these early ovulations is not well-established. The potential risk of pregnancy soon after delivery underscores the importance of initiating postpartum contraception in a timely fashion.

    To show the advantages of the use of vaginal misoprostol, a prostaglandine E1 analogue, in the prevention of the post-partum haemorrhage. This was a prospective, observational, comparative study. The study included 400 patients with high risk of postpartum haemorrhage at our center between January 1999 and may 2001. Patients were divided in two groups. In group I (208 patients) misoprostol was used in a dose of 800 ugr and in group II (192 patients) in whom misoprostol was not used. Both groups were treated initially with our conventional oxytocin protocol. We evaluated the use of additional oxytocin or ergotamine, haemoglobin levels pre and post-partum, the amount of blood loss, and the need for blood transfusion or hysterectomy. The need for additional oxytocin or ergotamine was reduced to less than 10% in group I when compared to group II; the drop in haemoglobin levels and the amount of blood loss were also less in group I (p: 0.03). In this group only one patient needed for blood transfusion and no patient needed hysterectomy. In group II six patients need a blood transfusion and there was the need for two hysterectomies. The use of vaginal misoprostol is effective to control the postpartum bleeding, reducing the blood loss after birth in women with high risk of post-partum haemorrhage as well as the need for blood transfusion. It's use has mild side effects and is of low cost.

    Full Text Available BACKGROUND Puerperium refers to the six-week period following childbirth. This is a dynamic period when the physiological changes that occur during pregnancy resolve and the body system return to their pre-pregnant state. Many of the complications leading to postpartum maternal morbidity arise during labour and delivery and in the first 1-2 weeks following delivery. The complication during immediate postpartum periods is managed in hospital itself. But, there is a risk of persisting these complications and from the postnatal checkup, the magnitude of the postpartum morbidity of these women are assessed. The aim of the study is to assess the postpartum physical morbidities among postnatal mothers and determine the association of those with selected variables. MATERIALS AND METHODS This is a descriptive study. Sample in this study consists of 406 consecutive cases of postnatal mothers after 6 weeks of postpartum period who are visiting Family Planning Outpatient Department of Sree Avittom Thirunal Hospital, Thiruvananthapuram, for postnatal checkup. Each woman was assessed by using interview schedule. The findings were presented under the following headings. Sociodemographic data, postpartum morbidities and association between selected variable and postpartum morbidities. Study Setting and Design- The design adopted is descriptive research design. 406 postnatal mothers attending the Family Planning Outpatient Department of Sree Avittom Thirunal Hospital, Thiruvananthapuram, for postnatal checkup after 6 weeks postpartum are allocated. Each woman was assessed by interview schedule. The physical postpartum morbidities among postnatal women were assessed. RESULTS Data was analysed using SPSS software using descriptive and inferential statistics based on the objective using frequency and Chi-square test. CONCLUSION In the present study, 57.6% of women had morbidities of which 29.3% had postpartum anaemia, 45.5% had backache, 15% had perineal pain, 16

    Full Text Available Post-parturient behavior of mammalian females is essential for early parent–offspring contact. After delivery, lambs need to ingest colostrum for obtaining the related immunological protection, and early interactions between the mother and the lamb are crucial. Despite visual and auditory cues, olfactory cues are decisive in lamb orientation to the mammary gland. In sheep, the inguinal sinus is located bilaterally near the mammary gland as a skin pouch (IGS that presents a gland that secretes a strong-smelling wax. Sheep IGS gland functions have many aspects under evaluation. The objective of the present study was to evaluate sheep IGS gland functional aspects and mRNA transcription and the protein expression of several hormone receptors, such as progesterone receptor (PGR, estrogen receptor 1 (ESR1, and 2 (ESR2 and prolactin receptor (PRLR present. In addition, another aim was to achieve information about IGS ultrastructure and chemical compounds produced in this gland. All hormone receptors evaluated show expression in IGS during the estrous cycle (follicular/luteal phases, pregnancy, and the post-partum period. IGS secretion is rich in triterpenoids that totally differ from the surrounding skin. They might be essential substances for the development of an olfactory preference of newborns to their mothers.

    There have been numerous studies of the prevalence of postpartum depression and its putative risk factors in Western Europe and North America, but very few studies in developing countries including the Arab world. Ninety-five women admitted to the New Dubai Hospital in Dubai, United Arab Emirates, for childbirth were studied. All subjects were assessed in the postpartum period using clinical and socio-cultural instruments: the Self Report Questionnaire (SRQ) at day 2, the Edinburgh Postnatal Depression Scale (EPDS) at day 7, and the Present State Examination (PSE) at week 8 +/- 2 and week 30 +/- 2 after delivery. The prevalence rate of psychiatric morbidity was 24.5% by the SRQ, 17.8% by the EPDS, and 15.8% by the PSE. A number of psychosocial factors emerged as putative risk factors for postpartum depression. The prevalence rates of postpartum psychiatric morbidity and its risk factors in this Arab culture are similar to the results obtained in numerous previous studies in industrialised countries. These findings have implications for the early detection and care of women at risk for postpartum depression.

    Objective: We seek to characterize the effect of progesterone metabolites on spontaneous and oxytocin-induced uterine contractility. Study Design: Spontaneous contractility was studied in mouse uterine horns after treatment with progesterone, 2α-hydroxyprogesterone, 6β-hydroxyprogesterone (6β-OHP), 16α-hydroxyprogesterone (16α-OHP), or 17-hydroxyprogesterone caproate (17-OHPC) at 10−9 to 10−6 mol/L. Uterine horns were exposed to progestins (10−6 mol/L), followed by increasing concentrations of oxytocin (1-100 nmol/L) to study oxytocin-induced contractility. Contraction parameters were compared for each progestin and matched vehicle control using repeated measures 2-way analysis of variance. In vitro metabolism of progesterone by recombinant cytochrome P450 3A (CYP3A) microsomes (3A5, 3A5, and 3A7) identified major metabolites. Results: Oxytocin-induced contractile frequency was decreased by 16α-OHP (P = .03) and increased by 6β-OHP (P = .05). Progesterone and 17-OHPC decreased oxytocin-induced contractile force (P = .02 and P = .04, respectively) and frequency (P = .02 and P = .03, respectively). Only progesterone decreased spontaneous contractile force (P = .02). Production of 16α-OHP and 6β-OHP metabolites were confirmed in all CYP3A isoforms tested. Conclusion: Progesterone metabolites produced by maternal or fetal CYP3A enzymes influence uterine contractility. PMID:26037300

    In this article we describe the knowledge frameworks that 61 physicians, nurses, social workers, and psychologists from five public-sector health care facilities in Mexico used to conceptualize postpartum depression. We also demonstrate how providers applied social and behavioral antecedents in their conceptualizations of postpartum depression. Using grounded theory, we identify two frameworks that providers used to conceptualize postpartum depression: biochemical and adjustment. We highlight an emerging model of the function of social and behavioral antecedents within the frameworks, as well as the representation of postpartum depression by symptoms of distress and the perception among providers that these symptoms affected responsibilities associated with motherhood. The results provide a foundation for future study of how providers' conceptualizations of postpartum depression might affect detection and treatment practices and might be useful in the development of training materials to enhance the quality of care for women who experience any form of distress in the postpartum period. © The Author(s) 2014.

    Background During the postpartum period, some women might be under a considerable amount of stress and at increased risk for onset or exacerbation of obsessive–compulsive disorder (OCD). Little is known about the stress response correlates during the postpartum period and in patients with OCD. This study aimed to examine the cerebral, psychologic and endocrine correlates of the stress response in patients with OCD and during the postpartum period. Methods Women with postpartum OCD, healthy postpartum women and healthy mothers past the postpartum period underwent functional magnetic resonance imaging while facing a reliable psychosocial stressor (the Montreal Imaging Stress Task). Stress-related psychologic and endocrine responses (i.e., cortisol) were obtained. Results We enrolled 12 women with postpartum OCD, 16 healthy postpartum women and 11 healthy mothers past the postpartum period in our study. Compared with healthy postpartum counterparts, postpartum women with OCD had a heightened self-reported and endocrine stress response associated with a distinct brain activation pattern in response to psychosocial stress involving the orbitofrontal and temporal cortices. Moreover, compared with mothers assessed in a period of time beyond the postpartum period, healthy postpartum women did not differ in psychologic and cortisol response to stress, but recruited different brain regions, such as the dorsolateral pre-frontal cortex and the anterior cingulate cortex, during exposure to stress. Limitations Potential confounding factors, such as medication use, breastfeeding, parity and personality factors, may have modulated the stress-related endocrine response and could not be assessed in this study. Conclusion Obsessive–compulsive disorder and the postpartum period differentially influence the brain circuitry underlying psychosocial stress as well as the psychologic and endocrine responses.

    Metabolites of [ 3 H]progesterone were quantitated from incubations of hypothalamus, pituitary, and uterus of rats during different stages of pregnancy. The hypothalamus, anterior pituitary, and a section of uterus from five rats on Days 1, 8, 15, and 21 of pregnancy were incubated individually with [3H]progesterone and analyzed for metabolite formation by reverse isotopic dilution analysis. The radioactive metabolites present were 5 alpha-pregnane-3,20-dione (5 alpha-DHP), 3 alpha-hydroxy-5 alpha-pregnan-20-one, 20 alpha-hydroxy-4-pregnen-3-one, 20 alpha-hydroxy-5 alpha-pregnan-3-one, and 5 alpha-pregnane-3 alpha, 20 alpha-diol. The major metabolite formed by the hypothalamus and pituitary was 5 alpha-DHP. In the pituitary samples, formation of 5 alpha-DHP was decreased on Days 15 and 21 of pregnancy compared to Day 1, and formation of 20 alpha-hydroxy-5 alpha-pregnan-3-one was decreased on Day 21 compared to Day 1. In the uterine samples, 3 alpha-hydroxy-5 alpha-pregnan-20-one was the major metabolite formed at all stages of pregnancy. The formation of all metabolic products of progesterone by the uterus was increased on Day 21 compared to Days 1, 8, and 15 of pregnancy. No changes in the formation of progesterone metabolites were observed in the hypothalamic samples during pregnancy. It is concluded that there are different profiles in the in vitro metabolism of [3H]progesterone by the hypothalamus, pituitary, and uterus of the rat during the course of pregnancy

    Rivaroxaban, a factor Xa inhibitor, is a direct-acting oral anticoagulant (DOAC) indicated for the treatment of deep vein thrombosis (DVT) and pulmonary embolism (PE), and for reducing the risk of DVT and PE recurrence. To our knowledge, no data are presently available to guide DOAC dosing in the postpartum period when pharmacokinetic and pharmacodynamic changes induced by pregnancy have an impact on drug clearance and increase hypercoagulability for a period of 6-8 weeks after delivery. We describe the case of a 35-year-old postpartum woman who presented to the emergency department with a diagnosis of a new multiple segmental PE 5 days after starting rivaroxaban therapy for a diagnosis of DVT. No precipitating cause, including noncompliance, was identified as a source of thrombosis embolization or extension. The patient was admitted, a heparin infusion was started for the management of PE, and rivaroxaban was discontinued. She was transitioned to enoxaparin 1 mg/kg (90 mg) subcutaneously every 12 hours the next day, bridged to warfarin, and discharged home on the overlapping regimen with close follow-up by the pharmacist-managed outpatient Anticoagulation Management Service. To our knowledge, this is the first case report of potential failure associated with rivaroxaban therapy in the postpartum period, possibly due to pharmacokinetic alterations seen in the postpartum period contributing to decreased drug exposure, yielding reduced anticoagulant efficacy. Clinicians should carefully weigh the risks and benefits of DOAC therapy in postpartum patients or other special populations requiring anticoagulation therapy. This report also highlights the need for further research identifying the impact of pharmacokinetic changes induced by special populations and the need to develop monitoring assays for such clinical situations. © 2015 Pharmacotherapy Publications, Inc.

    Background. Protease inhibitor (PI)–based combination antiretroviral therapy (cART) is administered during pregnancy to prevent perinatal human immunodeficiency virus (HIV) transmission. However, PI use has been associated with adverse birth outcomes, including preterm delivery and small-for-gestational-age (SGA) births. The mechanisms underlying these outcomes are unknown. We hypothesized that PIs contribute to these adverse events by altering progesterone levels. Methods. PI effects on trophoblast progesterone production were assessed in vitro. A mouse pregnancy model was used to assess the impact of PI-based cART on pregnancy outcomes and progesterone levels in vivo. Progesterone levels were assessed in plasma specimens from 27 HIV-infected and 17 HIV-uninfected pregnant women. Results. PIs (ritonavir, lopinavir, and atazanavir) but not nucleoside reverse transcriptase inhibitors (NRTIs) or nonnucleoside reverse transcriptase inhibitors reduced trophoblast progesterone production in vitro. In pregnant mice, PI-based cART but not dual-NRTI therapy was associated with significantly lower progesterone levels that directly correlated with fetal weight. Progesterone supplementation resulted in a significant improvement in fetal weight. We observed lower progesterone levels and smaller infants in HIV-infected women receiving PI-based cART, compared with the control group. In HIV-infected women, progesterone levels correlated significantly with birth weight percentile. Conclusions. Our data suggest that PI use in pregnancy may lead to lower progesterone levels that could contribute to adverse birth outcomes. PMID:25030058

    Human sperm cell function must be precisely regulated to achieve natural fertilization. Progesterone released by the cumulus cells surrounding the egg induces a Ca 2+ influx into human sperm cells via the CatSper Ca 2+ -channel and thereby controls sperm function. Multiple chemical UV filters have been shown to induce a Ca 2+ influx through CatSper, thus mimicking the effect of progesterone on Ca 2+ signaling. We hypothesized that these UV filters could also mimic the effect of progesterone on sperm function. We examined 29 UV filters allowed in sunscreens in the US and/or EU for their ability to affect acrosome reaction, penetration, hyperactivation and viability in human sperm cells. We found that, similar to progesterone, the UV filters 4-MBC, 3-BC, Meradimate, Octisalate, BCSA, HMS and OD-PABA induced acrosome reaction and 3-BC increased sperm penetration into a viscous medium. The capacity of the UV filters to induce acrosome reaction and increase sperm penetration was positively associated with the ability of the UV filters to induce a Ca 2+ influx. None of the UV filters induced significant changes in the proportion of hyperactivated cells. In conclusion, chemical UV filters that mimic the effect of progesterone on Ca 2+ signaling in human sperm cells can similarly mimic the effect of progesterone on acrosome reaction and sperm penetration. Human exposure to these chemical UV filters may impair fertility by interfering with sperm function, e.g. through induction of premature acrosome reaction. Further studies are needed to confirm the results in vivo . © 2018 The authors.

    Cocaine sensitization is a marker for some facets of addiction, is greater in female rats, and may be influenced by their sex hormones. We compared the modulatory effects of endogenous or exogenous estradiol and progesterone on cocaine-induced behavioral sensitization in 106 female rats. Ovariectomized female rats received progesterone (0.5 mg/mL), estradiol (0.05 mg/mL), progesterone plus estradiol, or the oil vehicle. Sham-operated control females received oil. Control and acute subgroups received injections of saline, while the repeated group received cocaine (15 mg/kg, ip) for 8 days. After 10 days, the acute and repeated groups received a challenge dose of cocaine, after which locomotion and stereotypy were monitored. The estrous cycle phase was evaluated and blood was collected to verify hormone levels. Repeated cocaine treatment induced overall behavioral sensitization in female rats, with increased locomotion and stereotypies. In detailed analysis, ovariectomized rats showed no locomotor sensitization; however, the sensitization of stereotypies was maintained. Only females with endogenous estradiol and progesterone demonstrated increased locomotor activity after cocaine challenge. Estradiol replacement enhanced stereotyped behaviors after repeated cocaine administration. Cocaine sensitization of stereotyped behaviors in female rats was reduced after progesterone replacement, either alone or concomitant with estradiol. The behavioral responses (locomotion and stereotypy) to cocaine were affected differently, depending on whether the female hormones were of an endogenous or exogenous origin. Therefore, hormonal cycling appears to be an important factor in the sensitization of females. Although estradiol increases the risk of cocaine sensitization, progesterone warrants further study as a pharmacological treatment in the prevention of psychostimulant abuse.

    For new mothers returning to work, the role of the workplace psychosocial environment on maternal mental health has not been fully described. The purpose of this study was to identify the relationship between psychosocial employment characteristics and mothers' postpartum depression, anxiety, and stress symptoms. Ninety-seven women answered survey questions regarding employment, job demand, control, and support, and postpartum depression, anxiety, and stress symptoms soon after live birth and 6 months later. Working and nonworking mothers reported similar mental health symptoms. Psychological characteristics of employment were not associated with increased odds of mental health symptoms. Increased social support provided by coworkers, supervisors, and the organization was associated with reduced odds of anxiety symptoms. Our findings identified lack of workplace social support as a modifiable risk factor for postpartum anxiety. Future evaluations of workplace social support interventions may be explored to improve postpartum mental health symptoms. Am. J. Ind.

    Much research has found that exposure to certain types of media portrayals of women can be related to body image concerns among women. The current paper focuses on the impact of certain messages on pregnant and postpartum women. These women are rarely examined in a media research context but are particularly vulnerable to body image concerns. This experimental study involved 192 pregnant or postpartum women who read a magazine containing glamorized media portrayals of pregnant/postpartum women or a control magazine. Pregnant women reported lower body image after only five minutes of exposure to the magazine with pregnant/postpartum women compared to the control group. There was no immediate effect on postpartum women. Implications for the media industry, health professionals, and women are discussed.

    Serum progesterone and thyroxin concentrations were measured weekly until 61 to 62 days after ovulation in 24 pregnant bitches and in the control group of nine nonpregnant bitches in the luteal phase. Fourteen of the 24 dogs had a normal pregnancy and parturition. Ten of the 24 dogs showed mucinous or colored vaginal discharge, decreased appetite, or lethargy. These initial signs of abortion or fetal resorption were noted during the fourth week of pregnancy, and the process occurred over the next 2 weeks. Progesterone and thyroxin concentrations were measured by quantitative ELISAs validated to dog serum. The serum progesterone concentrations of the group going through abortions differed significantly from the third week until the end of the eighth week. The mean serum thyroxin concentrations of healthy pregnant and nonpregnant groups significantly exceeded the reference range (20-45 nmol/L). The serum thyroxin concentrations in the abortion group were between 16.15 ± 3.17 and 40.78 ± 8.97 nmol/L. The values in this group were significantly different from the other two groups at the third week of the luteal phase. Clinical signs of abortion or fetus resorption manifested in midpregnancy. The clinical signs of abortion coincided in each case with a low serum progesterone concentration (<10 ng/mL). This phenomenon indicated, in contrast with other studies, that the decrease of serum progesterone below 10 ng/mL at the fourth week of pregnancy may signal impending abortion. In the second half of pregnancy, the thyroid gland was not able to respond adequately to the elevated requirement in thyroid hormone, although in other periods of the ovarian cycle, there were no clinical signs of hypothyroidism.

    Immediate postpartum intrauterine devices (IUDs) have been underutilized in the United States despite their known safety. Understanding how providers' attitudes contribute to underutilization is important in improving access. Our objective was to examine healthcare providers' perceptions of the safety of immediate postpartum IUDs before publication of United States contraceptive guidelines. We analyzed survey data collected from December 2009 to March 2010 from 635 office-based physicians and 1368 Title X clinic providers (overall response rate of 64.8%). Providers were asked how safe they thought copper and levonorgestrel (LNG) IUDs were in postpartum women (very safe, safe, unsafe, very unsafe, and unsure). Multivariable logistic regression was used to calculate adjusted odds ratios (aORs) and 95% confidence intervals (95% CIs) for characteristics associated with considering immediate and delayed postpartum IUDs to be safe. Less than 40% of respondents considered immediate or delayed IUD insertion to be safe. Providers with postpartum IUD insertion to be safe compared with unsafe/unsure (aOR 0.18, 95% CI 0.04-0.84 for copper IUD and aOR 0.17, 95% CI 0.04-0.81 for LNG-IUD). Providers without training in postpartum or interval copper IUD insertion had decreased odds of considering immediate postpartum copper IUD insertion (aOR 0.40, 95% CI 0.16-0.79) and delayed postpartum insertion for both IUD types to be safe (aOR 0.34, 95% CI 0.18-0.66 for copper IUD and aOR 0.41, 95% CI 0.21-0.77 for LNG-IUD). Before United States contraceptive guidelines, a majority of providers perceived immediate postpartum IUDs to be unsafe.

    Postpartum discharge instructions are a crucial part of a mother's birth experience. Finding the method to provide those discharge instructions in a manner that increases the mother's satisfaction with her hospital experience is important. This quasi-experimental study examined the relationship between new mothers' interaction with nurses providing postpartum instructions by the traditional and class methods and their satisfaction with discharge teaching. The results indicated new mothers were satisfied with both methods of discharge teaching; however, they were more likely to report stronger agreement with overall satisfaction with the traditional method of discharge teaching than with attending the discharge class.

    Progesterone promotes uterine relaxation and is essential for the maintenance of pregnancy. Withdrawal of progesterone activity and increased inflammation within the uterine tissues are key triggers for parturition. Progesterone actions in myometrial cells are mediated by two progesterone receptor (PR) isoforms, PR-A and PR-B, that function as ligand-activated transcription factors. PR-B mediates relaxatory actions of progesterone, in part, by decreasing myometrial cell responsiveness to pro-inflammatory stimuli. These same pro-inflammatory stimuli promote the expression of PR-A which inhibits the anti-inflammatory activity of PR-B. Competitive interaction between the progesterone receptors then augments myometrial responsiveness to pro-inflammatory stimuli. The interaction between PR-B transcriptional activity and inflammation in the pregnancy myometrium is examined using a dynamical systems model in which quiescence and labor are represented as phase-space equilibrium points. Our model shows that PR-B transcriptional activity and the inflammatory load determine the stability of the quiescent and laboring phenotypes. The model is tested using published transcriptome datasets describing the mRNA abundances in the myometrium before and after the onset of labor at term. Surrogate transcripts were selected to reflect PR-B transcriptional activity and inflammation status. The model coupling PR-B activity and inflammation predicts contractile status (i.e., laboring or quiescent) with high precision and recall and outperforms uncoupled single and two-gene classifiers. Linear stability analysis shows that phase space bifurcations exist in our model that may reflect the phenotypic states of the pregnancy uterus. The model describes a possible tipping point for the transition of the quiescent to the contractile laboring phenotype. Our model describes the functional interaction between the PR-A:PR-B hypothesis and tissue level inflammation in the pregnancy uterus and is a

    Selective progesterone receptor modulators are a class of drugs with progesterone antagonist activity that may confer therapeutic benefit for reproductive disorders in premenopausal women. Endometrial structure, which is dynamically controlled by circulating sex hormones, is likely to be perturbed by progesterone receptor modulators through their progesterone antagonist properties. We examined endometrial histology in 58 premenopausal women treated with the progesterone receptor modulator CDB-4124 (also known as Proellex) for endometriosis or uterine leiomyomata in two clinical trials. Endometrial biopsies obtained after 3 or 6 months with doses of 12.5, 25, or 50 mg daily oral CDB-4124 were reviewed independently by three pathologists. Consensus diagnoses using the World Health Organization hyperplasia scoring system, comments on specific histologic features, and clinical annotation were collected and analyzed. The majority of the endometrial biopsies (103 of 174 biopsies) contained histologic changes that are not seen during normal menstrual cycles. The histology of CDB-4124-treated patients was generally inactive or atrophic, and less frequently, proliferative or secretory, superimposed upon which were novel changes including formation of cystically dilated glands, and secretory changes coexisting with mitoses and apoptotic bodies. With increasing treatment dose and duration, the cysts became predominant and their lining inactive or atrophic. Cystic glands in the CDB-4124-treated subjects correlated with increased endometrial thickness by ultrasound. None of the CDB-4124-treated patients developed endometrial carcinoma or hyperplasia while on therapy. CDB-4124 therapy for 3-6 months produces histologic changes that are sufficiently novel that they might easily be misinterpreted by pathologists, particularly as disordered proliferative or hyperplastic endometrium.

    Slices of male guinea pig adrenals were incubated with a trace amount of /sup 3/H-7..cap alpha..-progesterone and the proportion of /sup 3/H incorporation various steroids at various intervals was measured. It was found that /sup 3/H accumulated predominantly in 11..beta..-hydroxyprogesterone as compared to DOC. This indicated that in guinea pig adrenals 11..beta..-hydroxyprogesterone plays a predominant role in the formation of corticosterone from progesterone. The observed sequence of changes in progesterone label accumulation in 17-hydroxycompounds indicated the pathway of cortisol synthesis through the intermediate formation of 17-hydroxyprogesterone and 11-deoxycortisol.

    Progesterone is a steroid hormone essential for the maintenance of human pregnancy, and its actions are thought to include promoting maternal immune tolerance of the semiallogenic fetus. We report that exposure of maternal T cells to progesterone at physiological doses induced a unique skewing of the cytokine production profile of CD4+ and CD8+ T cells, with reductions not only in potentially deleterious IFN‐γ and TNF‐α production but also in IL‐10 and IL‐5. Conversely, production of IL‐4 was increased. Maternal T cells also became less polyfunctional, focussing cytokine production toward profiles including IL‐4. This was accompanied by reduced T‐cell proliferation. Using fetal and viral antigen‐specific CD8+ T‐cell clones, we confirmed that this as a direct, nonantigen‐specific effect. Yet human T cells lacked conventional nuclear progesterone receptors, implicating a membrane progesterone receptor. CD4+ and CD8+ T cells responded to progesterone in a dose‐dependent manner, with subtle effects at concentrations comparable to those in maternal blood, but profound effects at concentrations similar to those at the maternal–fetal interface. This characterization of how progesterone modulates T‐cell function is important in understanding the normal biology of pregnancy and informing the rational use of progesterone therapy in pregnancies at risk of fetal loss.

    Full Text Available Background. Postpartum depression (PPD does great harm to women following childbirth. The aim of this study was to conduct a systematic review of the literature to assess the efficacy and safety of CHM for the treatment of PPD. Methods. Published or ongoing registered trials were searched for from the inception of the various databases to December 31, 2015. Data extraction and methodology assessment were conducted independently by two researchers. RevMan 5.3 software was used to analyze the data. Results. Forty-seven registered clinical trials (RCTs were identified and reviewed. The results showed CHM alone or in combination with routine treatments could reduce HAMD score, EPDS score, incidence of adverse events, TESS, and SERS. CHM combined with routine treatment was more effective in increasing serum estradiol levels and reducing progesterone levels than routine treatment alone. Meanwhile, pooled data revealed that MRLQS combined with routine treatments or MRLQS plus MSHS combined with routine treatments were more effective than other therapeutic methods in TCM. MRLQS plus MSHS alone was found to be an effective alternative when compared to routine treatments. Conclusions. This review suggested that CHM was safe and effective in the treatment of PPD. However, this could not be proven conclusively. To ensure evidence-based clinical practice, more rigorously designed trials are warranted.
