    To evaluate the hormonal profile in three breast cancer patients who underwent controlled ovarian stimulation in the presence of the aromatase inhibitor letrozole. In IVF University referral center, a case series of three breast cancer patients who underwent controlled ovarian stimulation (COS) with recombinant FSH and letrozole were investigated. Ovulation was induced with hCG (case No. 1) or with GnRH agonist (case No. 2-3). The primary outcome of our study was the detection of progesterone levels in the luteal phase. Very high progesterone values (mean 186.6 ± 43.6 ng/mL) during the luteal phase were recorded in all three cases. High progesterone levels can be related to the use of letrozole independently of the most commonly used trigger regimen. Although progesterone has long been considered a protective factor against breast cancer, several studies have demonstrated that progesterone could expand a transformation-sensitive stem cell population in the mammary glands. The estrogen negative feedback effect on the hypothalamus-pituitary axis and the disruption of steroid biosynthesis and could represent an intriguing reason behind this phenomenon. Our results highlight the need to evaluate further the increase in progesterone levels in the luteal phase in women with breast cancer undergoing COS with letrozole.

  2. Improving the luteal phase after ovarian stimulation

    Andersen, Claus Yding; Vilbour Andersen, K


    The human chorionic gonadotrophin (HCG) trigger used for final follicular maturation in connection with assisted reproduction treatment combines ovulation induction and early luteal-phase stimulation of the corpora lutea. The use of a gonadotrophin-releasing hormone agonist (GnRHa) for final...... follicular maturation has, however, for the first time allowed a separation of the ovulatory signal from the early luteal-phase support. This has generated new information that may improve the currently employed luteal-phase support. Thus, combined results from a number of randomized controlled trials using...

  3. Luteal phase administration of agents for the treatment of premenstrual dysphoric disorder.

    Freeman, Ellen W


    This review focuses on current information about luteal phase administration (i.e. typically for the last 2 weeks of the menstrual cycle) of pharmacological agents for the treatment of premenstrual dysphoric disorder (PMDD). Compared with continuous administration, a luteal phase administration regimen reduces the exposure to medication and lowers the costs of treatment. Based on evidence from randomised clinical trials, SSRIs are the first-line treatment for PMDD at this time. Of these agents, sertraline, fluoxetine and paroxetine (as an extended-release formulation) are approved by the US FDA for luteal phase, as well as continuous, administration. Clinical trials of these agents and citalopram have demonstrated that symptom reduction is similar with both administration regimens. When used to treat PMDD, SSRI doses are consistent with those used for major depressive disorder. The medications are well tolerated; discontinuation symptoms with this intermittent administration regimen have not been reported. Other medications that have been examined in clinical trials for PMDD or severe premenstrual syndrome (PMS) using luteal phase administration include buspirone, alprazolam, tryptophan and progesterone. Buspirone and alprazolam show only modest efficacy in PMS (in some but not all studies), but there may be a lower incidence of sexual adverse effects with these medications than with SSRIs. Symptom reduction with tryptophan was significantly greater than with placebo, but the availability of this medication is strictly limited because of safety concerns. Progesterone has consistently failed to show efficacy for severe PMS/PMDD in large, randomised, placebo-controlled trials.

  4. Luteal phase support for assisted reproduction cycles

    Linden, M. van der; Buckingham, K.; Farquhar, C.; Kremer, J.A.M.; Metwally, M.


    BACKGROUND: Progesterone prepares the endometrium for pregnancy by stimulating proliferation in response to human chorionic gonadotropin(hCG) produced by the corpus luteum. This occurs in the luteal phase of the menstrual cycle. In assisted reproduction techniques(ART), progesterone and/or hCG

  6. Treatment of premenstrual dysphoric disorder with luteal phase dosing of sertraline.

    Halbreich, Uriel; Kahn, Linda S


    Sertraline (Zoloft, Pfizer Inc.) is a selective serotonin re-uptake inhibitor (SSRI) which has been approved by the US FDA for the treatment of premenstrual dysphoric disorder (PMDD). PMDD is a severe form of premenstrual syndrome (PMS) which affects at least 5 - 8% of women of reproductive age. It is characterised by cyclic appearance at the late luteal phase of the menstrual cycle, and disappearance following the beginning of menses, with no symptoms during at least 1 week of the cycle - usually during the mid-follicular phase. Due to the cyclic luteal occurrence of PMDD, luteal phase dosing of SSRIs has been suggested and proven effective for sertraline as well as several other SSRIs. The clinical response of sertraline is reported to be within several days following initiation of treatment. Despite repeated cyclic discontinuation, no significant discontinuation adverse effects have been reported. In addition to its proven clinical efficacy, luteal-phase dosing may offer the advantages of minimising adverse effects of SSRIs while reducing the personal and economic burden of taking a prescription medication continuously for long periods and thus increasing compliance.

  7. Isolation and functional aspects of free luteal cells

    Luborsky, J.L.; Berhrman, H.R.


    Methods of luteal cell isolation employ enzymatic treatment of luteal tissue with collagenase and deoxyribonuclease. Additional enzymes such as hyaluronidase or Pronase are also used in some instances. Isolated luteal cells retain the morphological characteristics of steroid secreting cells after isolation. They contain mitochondria, variable amounts of lipid droplets, and an extensive smooth endoplasmic reticulum. Isolated luteal cells have been used in numerous studies to examine the regulation of steriodogenesis by luteinizing hormone (LH). LH receptor binding studies were employed to quantitate specific properties of hormone-receptor interaction in relation to cellular function. Binding of [ 125 I]LH to bovine luteal cells and membranes was compared and it was concluded that the enzymatic treatment used to isolate cells did not change the LH receptor binding kinetics

  8. Luteal function and conception in lactating cows and some factors influencing luteal function after first insemination.

    Hommeida, Abdelrahim; Nakao, Toshihiko; Kubota, Hirokazu


    The objective of this study was to investigate the types and incidence of luteal sub-function in lactating cows after artificial insemination (AI) and their relationship with pregnancy, and to clarify the relationship between luteal function and parity, body condition score (BCS), milk yield, and dietary intake. In 19 cows, milk samples were collected daily from AI to confirmation of pregnancy. Milk progesterone concentrations were determined by EIA. Based on peak progesterone concentration and the day of onset of luteal phase, 15 of 30 progesterone profiles (50%) were normal, with progesterone concentration reaching 1.0 ng/ml within 5 days after insemination and > or =2.0 ng/ml thereafter. In addition, 6 (20%) were insufficient, (progesterone concentration remained 1.0 ng/ml for only 7 days), and one (3%) remained basal. Cows with a normal profile had a higher (P rate than those with an abnormal profile (87% versus 33%, respectively). The amount of progesterone secreted in milk after first AI, as indicated by progesterone area under curve (AUC), was negatively correlated with milk yield (r = -0.83, P rates and high milk production and increased dietary intake during breeding were associated with reduced progesterone concentrations.

  10. The effect of metritis on luteal function in dairy cows


    Background Disturbed uterine involution impairs ovarian function in the first weeks after calving. This study analyzed the long-term effect of metritis on luteal function of 47 lactating Holstein-Friesian cows during the first four postpartum estrous cycles. Cows with abnormal uterine enlargement and malodorous lochia were classified as having metritis (group M, n = 18), and all others were considered healthy (group H, n = 29). Luteal size was measured once between days 9 and 13 of the first (group H, n = 11; group M, n = 12), second (group H, n = 23; group M, n = 18) and fourth (group H, n = 11; group M, n = 7) postpartum luteal phases. Serum progesterone concentration was measured at the same time. Sixteen cows (group H, n = 9; group M, n = 7) underwent transvaginal luteal biopsy for gene expression analysis of steroidogenic regulatory proteins during the second and fourth cycles. Cows with persistence of the corpus luteum (CL) underwent determination of luteal size, luteal biopsy and serum progesterone measurement once between days 29 and 33, followed by prostaglandin treatment to induce luteolysis. The same procedures were repeated once between days 9 and 13 of the induced cycle. Results The cows in group M had smaller first-cycle CLs than the cows in group H (p = 0.04), but progesterone concentrations did not differ between groups. Luteal size, progesterone concentration and gene expression did not differ between the two groups during the second and fourth cycles. Compared with healthy cows (10%), there was a trend (p = 0.07) toward a higher prevalence of persistent CLs in cows with metritis (33%). Persistent CLs were limited to the first cycle. Persistent CLs and the induced cyclic CLs did not differ with regard to the variables investigated. Conclusions An effect of metritis on luteal activity was apparent in the first postpartum estrous cycle. However, after the first postpartum cycle, no differences occurred

  11. Astaxanthin increases progesterone production in cultured bovine luteal cells.

    Kamada, Hachiro; Akagi, Satoshi; Watanabe, Shinya


    Although astaxanthin (AST) is known to be a strong antioxidant, its effects on reproductive function in domestic animals have not yet been elucidated in detail. Therefore, we investigated the effects of AST on luteal cells, which produce progesterone (P4), an important hormone for maintaining pregnancy. Luteal cells were prepared by collagenase dispersion of the corpus luteum (CL). The addition of racemic AST at a low concentration (production than RR-AST. When 1 mg/kg·body weight of SS-AST derived from green algae was fed to cows for 2 weeks, its concentration in blood plasma was 10.9 nM on average, which was sufficient to expect an in vitro effect on the production of P4 in cows. These results suggested the potential of SS-AST supplements for cows to elevate luteal function.

  12. Transcriptomes of bovine ovarian follicular and luteal cells

    Sarah M. Romereim


    Full Text Available Affymetrix Bovine GeneChip® Gene 1.0 ST Array RNA expression analysis was performed on four somatic ovarian cell types: the granulosa cells (GCs and theca cells (TCs of the dominant follicle and the large luteal cells (LLCs and small luteal cells (SLCs of the corpus luteum. The normalized linear microarray data was deposited to the NCBI GEO repository (GSE83524. Subsequent ANOVA determined genes that were enriched (≥2 fold more or decreased (≤−2 fold less in one cell type compared to all three other cell types, and these analyzed and filtered datasets are presented as tables. Genes that were shared in enriched expression in both follicular cell types (GCs and TCs or in both luteal cells types (LLCs and SLCs are also reported in tables. The standard deviation of the analyzed array data in relation to the log of the expression values is shown as a figure. These data have been further analyzed and interpreted in the companion article “Gene expression profiling of ovarian follicular and luteal cells provides insight into cellular identities and functions” (Romereim et al., 2017 [1].

  13. Degradation of high density lipoprotein in cultured rat luteal cells

    Rajan, V.P.; Menon, K.M.J.


    In rat ovary luteal cells, degradation of high density lipoprotein (HDL) to tricholoracetic acid (TCA)-soluble products accounts for only a fraction of the HDL-derived cholesterol used for steroidogenesis. In this study the authors have investigated the fate of 125 I]HDL bound to cultured luteal cells using pulse-chase technique. Luteal cell cultures were pulse labeled with [ 125 I]HDL 3 and reincubated in the absence of HDL. By 24 h about 50% of the initallay bound radioactivity was released into the medium, of which 60-65% could be precipitated with 10% TCA. Gel filtration of the chase incubation medium on 10% agarose showed that the amount of TCA-soluble radioactivity was nearly completely accounted for by a sharp peak in the low molecular weight region which was identified as 96% monoiodotyrosine by paper chromatography. The TCA-precipitable radioactivity was nearly completely accounted for by a sharp peak in the low molecular weight region which was identified as 96% monoiodotyrosine by paper chromatography. The TCA-precipitable radioactivity eluted over a wide range of molecular weights (15,000-80,000), and there was very little intact HDL present. Electrophoresis of the chase medium showed that component of the TCA-precipitable portion had mobility similar to apo AI. Lysosomal inhibitors of receptor-mediated endocytosis had no effect on the composition or quantity of radioactivity released during chase incubation. The results show that HDL 3 binding to luteal cells is followed by complete degradation of the lipoprotein, although the TCA-soluble part does not reflect the extent of degradation

  14. The methoxychlor metabolite, HPTE, inhibits rat luteal cell progesterone production.

    Akgul, Yucel; Derk, Raymond C; Meighan, Terence; Rao, K Murali Krishna; Murono, Eisuke P


    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.

  15. Luteal blood flow in patients undergoing GnRH agonist long protocol

    Takasaki Akihisa


    Full Text Available Abstract Background Blood flow in the corpus luteum (CL is closely related to luteal function. It is unclear how luteal blood flow is regulated. Standardized ovarian-stimulation protocol with a gonadotropin-releasing hormone agonist (GnRHa long protocol causes luteal phase defect because it drastically suppresses serum LH levels. Examining luteal blood flow in the patient undergoing GnRHa long protocol may be useful to know whether luteal blood flow is regulated by LH. Methods Twenty-four infertile women undergoing GnRHa long protocol were divided into 3 groups dependent on luteal supports; 9 women were given ethinylestradiol plus norgestrel (Planovar orally throughout the luteal phase (control group; 8 women were given HCG 2,000 IU on days 2 and 4 day after ovulation induction in addition to Planovar (HCG group; 7 women were given vitamin E (600 mg/day orally throughout the luteal phase in addition to Planovar (vitamin E group. Blood flow impedance was measured in each CL during the mid-luteal phase by transvaginal color-pulsed-Doppler-ultrasonography and was expressed as a CL-resistance index (CL-RI. Results Serum LH levels were remarkably suppressed in all the groups. CL-RI in the control group was more than the cutoff value (0.51, and only 2 out of 9 women had CL-RI values Conclusion Patients undergoing GnRHa long protocol had high luteal blood flow impedance with very low serum LH levels. HCG administration improved luteal blood flow impedance. This suggests that luteal blood flow is regulated by LH.

  16. Effects of cholesterol on progesterone production by goat luteal cell subpopulations at two different stages of the luteal phase.

    Arikan, Ş; Kalender, H; Simsek, O


    The aim of the present study was to evaluate the effects of cholesterol on progesterone production during long-term culturing of luteal cell subpopulations at early and late luteal stages of the goat corpora lutea. Corpora lutea were collected from Angora goats on days 5 and 15 of the oestrous cycle. Luteal cells were isolated by collagenase digestion. The cells were separated into two distinct subpopulations by Percoll density-gradient centrifugation. Both subpopulations of luteal cells staining positively for 3β-HSD activities (5 × 10(4)  cell/well) were cultured with or without 22(R)-hydroxycholesterol (22R-HC) in serum-free culture medium for periods of up to 7 days. Cells were incubated with serum (10%) for the first 18 h of incubation followed by serum-free medium. Cell treatment (10 and 20 μg/ml) was performed on days 1, 3 and 5. Treatment of cells with both concentrations of 22R-HC resulted in significant (p  0.05) on progesterone production in both fractions of cells throughout 7 days of incubation. Treatment of the cells with cholesterol resulted in 2.5- and 9.0-fold increases in progesterone accumulation on day 3 of incubation. Steroid production was maintained throughout the incubations when cells are incubated in serum-free media treated with cholesterol and ITS premix. Cells collected from higher density of percoll layers produced 2.82 and 2.32 times more progesterone, in comparison to the lover density percoll layer, on days 5 and 15 of the oestrous cycle in untreated cell groups, respectively. Progesterone accumulation was decreased as incubation time advanced in all groups of untreated cells. These results demonstrated that goat luteal cell subpopulations secrete substantial amounts of progesterone in response to cholesterol treatment at least for 7 days, and cholesterol is required as progesterone precursor for maintaining a high-level steroidogenesis during long-life culturing of both cell subpopulations. © 2010 Blackwell

  17. Ruptured corpus luteal cyst: Prediction of clinical outcomes with CT

    Lee, Myoung Seok; Moon, Min Hoan; Woo, Hyun Sik; Sung, Chang Kyu; Jeon, Hye Won; Lee, Taek Sang [SMG-SNU Boramae Medical Center, Seoul National University College of Medicine, Seoul (Korea, Republic of)


    To evaluate the determinant pretreatment CT findings that can predict surgical intervention for patients suffering from corpus luteal cyst rupture with hemoperitoneum. From January 2009 to December 2014, a total of 106 female patients (mean age, 26.1 years; range, 17–44 years) who visited the emergency room of our institute for acute abdominal pain and were subsequently diagnosed with ruptured corpus luteal cyst with hemoperitoneum were included in the retrospective study. The analysis of CT findings included cyst size, cyst shape, sentinel clot sign, ring of fire sign, hemoperitoneum depth, active bleeding in portal phase and attenuation of hemoperitoneum. The comparison of CT findings between the surgery and conservative management groups was performed with the Mann-Whitney U test or chi-square test. Logistic regression analysis was used to determine significant CT findings in predicting surgical intervention for a ruptured cyst. Comparative analysis revealed that the presence of active bleeding and the hemoperitoneum depth were significantly different between the surgery and conservative management groups and were confirmed as significant CT findings for predicting surgery, with adjusted odds ratio (ORs) of 3.773 and 1.318, respectively (p < 0.01). On the receiver-operating characteristic curve analysis for hemoperitoneum depth, the optimal cut-off value was 5.8 cm with 73.7% sensitivity and 58.6% specificity (Az = 0.711, p = 0.004). In cases with a hemoperitoneum depth > 5.8 cm and concurrent active bleeding, the OR for surgery increased to 5.786. The presence of active bleeding and the hemoperitoneum depth on a pretreatment CT scan can be predictive warning signs of surgery for a patient with a ruptured corpus luteal cyst with hemoperitoneum.

  18. YBCO SQUIDs with unconventional current phase relation

    Bauch, T.; Johansson, J.; Cedergren, K.; Lindstroem, T.; Lombardi, F.


    We have studied the dynamics of YBa 2 Cu 3 O 7-δ (YBCO) dc sperconducting quantum interference devices (SQUIDs) characterized by an unconventional Josephson current phase relation (CPR). We have focused on SQUID configurations with Josephson junctions where the lobe of the order parameter in one electrode is facing a node in the other electrode. This order parameter arrangement should enhance the appearance of a sin(2φ) term in the CPR. The response of the critical current of the dc SQUID, under the effect of an external magnetic field, has been measured in temperature, down to 20 mK. Our experimental data have been compared with numerical simulations of the SQUIDs dynamics by considering a CPR of a single junction of the form I(φ) = I I sin(φ) - I II sin(2φ) where I I and I II are, respectively, the first and second harmonic component. In our devices the values of the sin(2φ) term are such that the fundamental state of the SQUID is naturally double degenerate. This is of great relevance for applications of d-wave SQUIDs in quantum information processing

  19. Relationship of oestrus synchronization method, circulating hormones, luteinizing hormone and prostaglandin F-2 alpha receptors and luteal progesterone concentration to premature luteal regression in superovulated sheep.

    Schiewe, M C; Fitz, T A; Brown, J L; Stuart, L D; Wildt, D E


    Ewes were treated with exogenous follicle-stimulating hormone (FSH) and oestrus was synchronized using either a dual prostaglandin F-2 alpha (PGF-2 alpha) injection regimen or pessaries impregnated with medroxy progesterone acetate (MAP). Natural cycling ewes served as controls. After oestrus or AI (Day 0), corpora lutea (CL) were enucleated surgically from the left and right ovaries on Days 3 and 6, respectively. The incidence of premature luteolysis was related (P less than 0.05) to PGF-2 alpha treatment and occurred in 7 of 8 ewes compared with 0 of 4 controls and 1 of 8 MAP-exposed females. Sheep with regressing CL had lower circulating and intraluteal progesterone concentrations and fewer total and small dissociated luteal cells on Day 3 than gonadotrophin-treated counterparts with normal CL. Progesterone concentration in the serum and luteal tissue was higher (P less than 0.05) in gonadotrophin-treated ewes with normal CL than in the controls; but luteinizing hormone (LH) receptors/cell were not different on Days 3 and 6. There were no apparent differences in the temporal patterns of circulating oestradiol-17 beta, FSH and LH. High progesterone in gonadotrophin-treated ewes with normal CL coincided with an increase in total luteal mass and numbers of cells, which were primarily reflected in more small luteal cells than in control ewes. Gonadotrophin-treated ewes with regressing CL on Day 3 tended (P less than 0.10) to have fewer small luteal cells and fewer (P less than 0.05) low-affinity PGF-2 alpha binding sites than sheep with normal CL. By Day 6, luteal integrity and cell viability was absent in ewes with prematurely regressed CL. These data demonstrate that (i) the incidence of premature luteal regression is highly correlated with the use of PGF-2 alpha; (ii) this abnormal luteal tissue is functionally competent for 2-3 days after ovulation, but deteriorates rapidly thereafter and (iii) luteal-dysfunctioning ewes experience a reduction in numbers of

  20. The role of adrenergic activation on murine luteal cell viability and progesterone production.

    Wang, Jing; Tang, Min; Jiang, Huaide; Wu, Bing; Cai, Wei; Hu, Chuan; Bao, Riqiang; Dong, Qiming; Xiao, Li; Li, Gang; Zhang, Chunping


    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.

  1. Effects of metformin treatment on luteal phase progesterone concentration in polycystic ovary syndrome

    Meenakumari K.J.


    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.

  2. Characterization of hormonal profiles during the luteal phase in regularly menstruating women.

    Ecochard, Rene; Bouchard, Thomas; Leiva, Rene; Abdulla, Saman; Dupuis, Olivier; Duterque, Olivia; Garmier Billard, Marie; Boehringer, Hans; Genolini, Christophe


    To characterize the variability of hormonal profiles during the luteal phase in normal cycles. Observational study. Not applicable. Ninety-nine women contributing 266 menstrual cycles. The women collected first morning urine samples that were analyzed for estrone-3-glucuronide, pregnanediol-3-alpha-glucuronide (PDG), FSH, and LH. The women had serum P tests (twice per cycle) and underwent ultrasonography to identify the day of ovulation. The luteal phase was divided into three parts: the early luteal phase with increasing PDG (luteinization), the midluteal phase with PDG ≥10 μg/mg Cr (progestation), and the late luteal phase (luteolysis) when PDG fell below 10 μg/mg Cr. Long luteal phases begin with long luteinization processes. The early luteal phase is marked by low PDG and high LH levels. Long luteinization phases were correlated with low E1G and low PDG levels at day 3. The length of the early luteal phase is highly variable between cycles of the same woman. The duration and hormonal levels during the rest of the luteal phase were less correlated with other characteristics of the cycle. The study showed the presence of a prolonged pituitary activity during the luteinization process, which seems to be modulated by an interaction between P and LH. This supports a luteal phase model with three distinct processes: the first is a modulated luteinization process, whereas the second and the third are relatively less modulated processes of progestation and luteolysis.

  3. The luteal phase after GnRH-agonist triggering of ovulation: present and future perspectives

    Humaidan, Peter; Papanikolaou, E G; Kyrou, D


    In stimulated IVF/intracytoplasmic sperm injection cycles, the luteal phase is disrupted, necessitating luteal-phase supplementation. The most plausible reason behind this is the ovarian multifollicular development obtained after ovarian stimulation, resulting in supraphysiological steroid...... with a GnRH agonist instead of human chorionic gonadotrophin (HCG). The first studies applying this concept, however, showed a very poor pregnancy rate, despite standard luteal-phase support with progesterone. This review discusses the reason for the poor results and the newest studies, using GnRH agonist...

  5. Luteal function during the estrous cycle in arginine-treated ewes fed different planes of nutrition.

    Bass, Casie S; Redmer, Dale A; Kaminski, Samantha L; Grazul-Bilska, Anna T


    Functions of corpus luteum (CL) are influenced by numerous factors including hormones, growth and angiogenic factors, nutritional plane and dietary supplements such as arginine (Arg), a semi-essential amino acid and precursor for proteins, polyamines and nitric oxide (NO). The aim of this study was to determine if Arg supplementation to ewes fed different planes of nutrition influences: (1) progesterone (P4) concentrations in serum and luteal tissue, (2) luteal vascularity, cell proliferation, endothelial NO synthase (eNOS) and receptor (R) soluble guanylate cyclase β protein and mRNA expression and (3) luteal mRNA expression for selected angiogenic factors during the estrous cycle. Ewes (n = 111) were categorized by weight and randomly assigned to one of three nutritional planes: maintenance control (C), overfed (2× C) and underfed (0.6× C) beginning 60 days prior to onset of estrus. After estrus synchronization, ewes from each nutritional plane were assigned randomly to one of two treatments: Arg or saline. Serum and CL were collected at the early, mid and late luteal phases. The results demonstrated that: (1) nutritional plane affected ovulation rates, luteal vascularity, cell proliferation and NOS3, GUCY1B3, vascular endothelial growth factor (VEGF) and VEGFR2 mRNA expression, (2) Arg affected luteal vascularity, cell proliferation and NOS3, GUCY1B3, VEGF and VEGFR2 mRNA expression and (3) luteal vascularity, cell proliferation and the VEGF and NO systems depend on the stage of the estrous cycle. These data indicate that plane of nutrition and/or Arg supplementation can alter vascularization and expression of selected angiogenic factors in luteal tissue during the estrous cycle in sheep. © 2017 Society for Reproduction and Fertility.

  6. Luteal activity of pregnant rats with hypo-and hyperthyroidism.

    Silva, Juneo Freitas; Ocarino, Natália Melo; Serakides, Rogéria


    Luteal activity is dependent on the interaction of various growth factors, cytokines and hormones, including the thyroid hormones, being that hypo- and hyperthyroidism alter the gestational period and are also a cause of miscarriage and stillbirth. Because of that, we evaluated the proliferation, apoptosis and expression of angiogenic factors and COX-2 in the corpus luteum of hypo- and hyperthyroid pregnant rats. Seventy-two adult female rats were equally distributed into three groups: hypothyroid, hyperthyroid and control. Hypo- and hyperthyroidism were induced by the daily administration of propylthiouracil and L-thyroxine, respectively. The administration began five days before becoming pregnant and the animals were sacrificed at days 10, 14, and 19 of gestation. We performed an immunohistochemical analysis to evaluate the expression of CDC-47, VEGF, Flk-1 (VEGF receptor) and COX-2. Apoptosis was evaluated by the TUNEL assay. We assessed the gene expression of VEGF, Flk-1, caspase 3, COX-2 and PGF2α receptor using real time RT-PCR. The data were analyzed by SNK test. Hypothyroidism reduced COX-2 expression on day 10 and 19 (P Hyperthyroidism increased the expression of COX-2 on day 19 (P hyperthyroid animals, being this effect dependent of the gestational period.

  7. The Luteal Phase after GnRHa Trigger-Understanding An Enigma

    Kathrine Leth-Moller


    Full Text Available The luteal phase of all stimulated in vitro fertilization/intra-cytoplasmic sperm injection (IVF/ICSI cycles is disrupted, which makes luteal phase support (LPS mandatory. The cause of the disruption is thought to be the multifollicular development achieved during ovarian stimulation which results in supraphysiological concentrations of steroids secreted by a high number of corpora lutea during the early luteal phase. This will directly inhibit luteinizing hormone (LH secretion by the pituitary via negative feedback at the level of the hypothalamic-pituitary axis, leading to a luteal phase defect. With the introduction of the gonadotropin-releasing hormone (GnRH antagonist protocol, it became feasible to trigger final oocyte maturation and ovulation with a single bolus of GnRH agonist (GnRHa as an alternative to human chorionic gonadotropin (hCG. GnRHa triggering presents several advantages, including the reduction in or even elimination of ovarian hyperstimulation syndrome. Despite the potential advantages of GnRHa triggering, previous randomized controlled trials reported a poor clinical outcome with high rates of early pregnancy losses, despite supplementation with a standard LPS in the form of progesterone and estradiol. Following these disappointing results, several studies now report a luteal phase rescue after modifications of the LPS, resulting in a reproductive outcome comparable to that seen after hCG triggering. We herein review luteal phase differences between the natural cycle, hCG trigger and GnRHa trigger and present the most recent data on handling the luteal phase after GnRHa triggering.

    Mohammed, Bushra T; Sontakke, Sadanand D; Ioannidis, Jason; Duncan, W Colin; Donadeu, F Xavier


    Inadequate progesterone production from the corpus luteum is associated with pregnancy loss. Data available in model species suggest important roles of microRNAs (miRNAs) in luteal development and maintenance. To comprehensively investigate the involvement of miRNAs during the ovarian follicle-luteal transition. The effects of specific miRNAs on survival and steroid production by human luteinized granulosa cells (hLGCs) were tested using specific miRNA inhibitors. Candidate miRNAs were identified through microarray analyses of follicular and luteal tissues in a bovine model. An academic institution in the United Kingdom associated with a teaching hospital. hLGCs were obtained by standard transvaginal follicular-fluid aspiration from 35 women undergoing assisted conception. Inhibition of candidate miRNAs in vitro. Levels of miRNAs, mRNAs, FOXO1 protein, apoptosis, and steroids were measured in tissues and/or cultured cells. Two specific miRNA clusters, miR-183-96-182 and miR-212-132, were dramatically increased in luteal relative to follicular tissues. miR-96 and miR-132 were the most upregulated miRNAs within each cluster. Database analyses identified FOXO1 as a putative target of both these miRNAs. In cultured hLGCs, inhibition of miR-96 increased apoptosis and FOXO1 protein levels, and decreased progesterone production. These effects were prevented by small interfering RNA-mediated downregulation of FOXO1. In bovine luteal cells, miR-96 inhibition also led to increases in apoptosis and FOXO1 protein levels. miR-96 targets FOXO1 to regulate luteal development through effects on cell survival and steroid production. The miR-183-96-182 cluster could provide a novel target for the manipulation of luteal function. Copyright © 2017 Endocrine Society

  10. Current-phase relations and noise in rf biased SQUIDS

    Jackel, L.D.; Clark, T.D.; Buhrman, R.A.


    An investigation was made of the effect of the weak link current-phase relation on noise in rf biased SQUIDs. Non-sinusoidal current-phase relations were observed in various weak links, and these non-sinusoidal relations were correlated with significantly increased intrinsic noise in the SQUID ring. The current-phase relation was also found to affect the amplitude of the rf SQUID ring dissipation. The result of an rf SQUID system noise analysis shows that, due to increased intrinsic noise and reduced ring dissipation, the minimum attainable noise for a SQUID ring having a very non-sinusoidal current-phase relation is considerably greater than for a ring with a sinusoidal relation

  11. Menstrual phase-related differences in the pulsatility index on the central retinal artery suggest an oestrogen vasodilatation effect that antagonizes with progesterone.

    Viana, Luiz Carlos; Faria, Marcos; Pettersen, Heverton; Sampaio, Marcos; Geber, Selmo


    The actual effect of steroid hormones on cerebral microcirculation is still controversial. Therefore, the aim of our study was to investigate vascular flow variations in the central retinal artery that may exist during the ovulatory menstrual cycle. A total of 34 healthy women were included in this observational, longitudinal, and prospective study. All participants were submitted to dopplerfluxometric evaluation of the eyes in order to study the pulsatility index (PI) of the central retinal arteries, during four phases of the menstrual cycle: early follicular, mid follicular, periovulatory, and mid luteal phases. Subjects' ages ranged from 14 to 47 years old (mean: 29.7 ± 10.1) and PI did not differ among age groups. The PI of the central retinal artery was different among the four phases of the menstrual cycle. PI showed a significant decrease from early follicular phase (1.72) to mid follicular phase (1.57) (p = 0.037), and was similar during periovulatory phase (1.56) and significantly increased in mid luteal phase (1.70). After that it returned to the values observed in the early follicular phase. Our results suggest the existence of an oestrogen vasodilatation effect on the central retinal artery that is menstrual phase-related and antagonized by progesterone.

  12. Cytological image of the endometrium in cows in follicular and luteal phases of the ovarian cycle and in cows with follicular and luteal ovarian cysts

    Brodzki Piotr


    Full Text Available The experiment was conducted on 30 Holstein-Friesian cows: 10 cows in the follicular phase of the cycle and in the luteal phase 10 d later, 10 cows with follicular cysts, and 10 with luteal cysts. The presence of the ovarian structures was confirmed by ultrasonography. Serum levels of progesterone and 17β-oestradiol were tested with ELISA. Samples for cytological examination were collected from the uterus of all cows using a cytological brush. Following staining, the smears were evaluated in terms of quality and percentages of endometrial cells. In the follicular phase of the oestrous cycle, cells of type A - superficial cells (64.6 ± 4.48 were proportionally the largest group of cells. Cells of type C - basal cells (19.8 ± 2.75 were also present. In the luteal phase, the highest percentage of cells was of type B - intermediate cells (76.9 ± 4.26. When follicular cysts were present on the ovaries, the cytology resembled the follicular phase of the cycle, but with many younger type C cells (33.1 ± 4.11. In the case of luteal cysts on the ovaries, the cytology was similar to that of the luteal phase of the cycle, however with a lower percentage of type B cells (58.1 ± 5.71, and a slightly higher percentage of the other types. The differences in the cytological image of the uterus when different ovarian structures are present, depend on the hormonal activity of those structures. Due to the lack of literature data, the results of the study are important as a model, and may substantially facilitate identification of phases of the oestrus cycle, or the pathologies described, as well as indicate the current status of the endometrium

  13. The inter-relationship of premenstrual symptoms.

    Mira, M; Abraham, S; McNeil, D; Vizzard, J; Macaskill, P; Fraser, I; Llewellyn-Jones, D


    The prospective symptom reports of women seeking treatment for premenstrual symptoms and control subjects was investigated. In order to compare symptom reports from premenstrual symptom sufferers and control subjects a method of combining and analysing prospectively collected menstrual cycle symptom data is required. A technique that uses the time of onset of menses and the time of ovulation (as measured by urinary luteinizing hormone excretion) to standardize each cycle into 14 time points was developed. Summary factors were then empirically derived from data collected prospectively from 30 premenstrual symptom sufferers and 19 control subjects. Twenty-two mood symptoms were summarized into a single factor and the 29 most frequently occurring physical symptoms were summarized into two factors. Factor scores were calculated on the basis of these factors and the effect of time during the menstrual cycle on these scores examined. Both physical symptom factor scores increased significantly in the luteal phase for both the premenstrual symptom sufferer group and the control group. The single mood factor score increased significantly in the luteal phase for the premenstrual sufferer group but not for the control group, suggesting that the only qualitative difference between the groups was the presence of cyclic mood symptoms in the premenstrual symptom sufferer group. The premenstrual symptom sufferer group recorded significantly higher scores on each of the three factors than the control group. The correlation between the scores on each of the factors over three cycles was high both in the follicular and luteal phase suggesting that these factor scores provide a reproducible measure of menstrual cycle symptomatology.

  14. Colour Doppler Ultrasonography as a Tool to Assess Luteal Function in Santa Inês Ewes.

    Figueira, L M; Fonseca, J F; Arashiro, Ekn; Souza-Fabjan, Jmg; Ribeiro, Acs; Oba, E; Viana, Jhm; Brandão, F Z


    The aim of this study was to evaluate luteal dynamics in the Santa Inês ewes using colour Doppler (CD) ultrasonography. Oestrus was synchronized in nulliparous females (n = 18), and subsequently, they were only teased (n = 6) or teased and mated (n = 12). Blood samples were collected daily for plasma progesterone (P4 ) concentrations. Ultrasonographic images of corpora lutea (CL) in CD mode were obtained for further analysis in its largest diameter. The CD mode allowed an early sequential monitoring of CL that was visualized by the first time 0.77 ± 0.62 days after ovulation, with luteal area 29.68 ± 13.21 mm(2) . During the luteogenesis, a progressive increase was observed, followed by a plateau of luteal area, vascularization area and plasma concentrations of P4 reaching maximum values in D11 (124.0 ± 38.0 mm(2) , 52.78 ± 24.08 mm(2) and 11.23 ± 4.89 ng/ml, respectively). In the luteolysis, the plasma concentrations of P4 decreased sharply, whereas luteal and vascularization area gradually. The vascularization area was positively correlated with plasma concentrations of P4 during the luteogenesis (r = 0.22) and luteolysis (r = 0.48). The luteal dynamics of Santa Inês ewes showed patterns similar to those observed in other sheep breeds studied. The CD ultrasonography has the potential to be used as a tool to assess luteal function in sheep. © 2015 Blackwell Verlag GmbH.

  15. Luteal phase of the menstrual cycle increases sweating rate during exercise

    Garcia A.M.C.


    Full Text Available The present study evaluated whether the luteal phase elevation of body temperature would be offset during exercise by increased sweating, when women are normally hydrated. Eleven women performed 60 min of cycling exercise at 60% of their maximal work load at 32ºC and 80% relative air humidity. Each subject participated in two identical experimental sessions: one during the follicular phase (between days 5 and 8 and the other during the luteal phase (between days 22 and 25. Women with serum progesterone >3 ng/mL, in the luteal phase were classified as group 1 (N = 4, whereas the others were classified as group 2 (N = 7. Post-exercise urine volume (213 ± 80 vs 309 ± 113 mL and specific urine gravity (1.008 ± 0.003 vs 1.006 ± 0.002 changed (P < 0.05 during the luteal phase compared to the follicular phase in group 1. No menstrual cycle dependence was observed for these parameters in group 2. Sweat rate was higher (P < 0.05 in the luteal (3.10 ± 0.81 g m-2 min-1 than in the follicular phase (2.80 ± 0.64 g m-2 min-1 only in group 1. During exercise, no differences related to menstrual cycle phases were seen in rectal temperature, heart rate, rate of perceived exertion, mean skin temperature, and pre- and post-exercise body weight. Women exercising in a warm and humid environment with water intake seem to be able to adapt to the luteal phase increase of basal body temperature through reduced urinary volume and increased sweating rate.

  17. Effects of concanavalin A on the progesterone production by bovine steroidogenic luteal cells in vitro.

    Destro, F C; Martin, I; Landim-Alvarenga, Fdc; Ferreira, Jcp; Pate, J L


    The aim of this study was to evaluate the effects of concanavalin A (CONA) on the progesterone (P4) production by bovine steroidogenic luteal cells (LCs) in vitro. Luteal cells were collected during the mid-luteal stage (at 10-12 days following ovulation) and processed in the laboratory. Luteal cells were grown for 7 days in a humid atmosphere with 5% CO2 , with or without 10% foetal bovine serum, and were subjected to the following treatments: control: no treatment; CONA (10 μg/ml); LH (100 μg/ml); CONA + LH; LH (100 μg/ml) + prostaglandin F2α (PGF2α) (10 ng/ml); CONA + LH + PGF2α. Samples of the culture media were collected on days 1 (D1) and 7 (D7) for P4 quantification. The cells were counted on D7 of culture. Differences between treatments were considered statistically significant at p < .05. Culture in the presence of CONA decreased the P4-secreting capacity of LCs on D7 of culture, particularly in the absence of serum. The cell numbers did not change between treatments. © 2016 Blackwell Verlag GmbH.

  18. OCT-4 expression in follicular and luteal phase endometrium: a pilot study

    Huber Johannes C


    Full Text Available Abstract Background The stem cell marker Octamer-4 (OCT-4 is expressed in human endometrium. Menstrual cycle-dependency of OCT-4 expression has not been investigated to date. Methods In a prospective, single center cohort study of 98 women undergoing hysteroscopy during the follicular (n = 49 and the luteal (n = 40 phases of the menstrual cycle, we obtained endometrial samples. Specimens were investigated for OCT-4 expression on the mRNA and protein levels using reverse transcriptase polymerase chain reaction (RT-PCR and immunohistochemistry. Expression of OCT-4 was correlated to menstrual cycle phase. Results Of 89 women sampled, 49 were in the follicular phase and 40 were in the luteal phase. OCT-4 mRNA was detected in all samples. Increased OCT-4 mRNA levels in the follicular and luteal phases was found in 35/49 (71% and 27/40 (68% of women, respectively (p = 0.9. Increased expression of OCT-4 protein was identified in 56/89 (63% samples. Increased expression of OCT-4 protein in the follicular and luteal phases was found in 33/49 (67% and 23/40 (58% of women, respectively (p = 0.5. Conclusions On the mRNA and protein levels, OCT-4 is not differentially expressed during the menstrual cycle. Endometrial OCT-4 is not involved in or modulated by hormone-induced cyclical changes of the endometrium.

  20. Effects of electroacupuncture on luteal regression and steroidogenesis in ovarian hyperstimulation syndrome model rat.

    Huang, Xuan; Chen, Li; Xia, You-Bing; Xie, Min; Sun, Qin; Yao, Bing


    Electroacupuncture (EA) is an effective and safe therapeutic method widely used for treating clinical diseases. Previously, we found that EA could decrease serum hormones and reduce ovarian size in ovarian hyperstimulation syndrome (OHSS) rat model. Nevertheless, the mechanisms that contribute to these improvements remain unclear. HE staining was used to count the number of corpora lutea (CL) and follicles. Immunohistochemical and ELISA were applied to examine luteal functional and structural regression. Immunoprecipitation was used for analyzing the interaction between NPY (neuropeptide Y) and COX-2; western blotting and qRT-PCR were used to evaluate the expressions of steroidogenic enzymes and PKA/CREB pathway. EA treatment significantly reduced the ovarian weight and the number of CL, also decreased ovarian and serum levels of PGE2 and COX-2 expression; increased ovarian PGF2α levels and PGF2α/PGE2 ratio; decreased PCNA expression and distribution; and increased cyclin regulatory inhibitor p27 expression to have further effect on the luteal formation, and promote luteal functional and structural regression. Moreover, expression of COX-2 in ovaries was possessed interactivity increased expression of NPY. Furthermore, EA treatment lowered the serum hormone levels, inhibited PKA/CREB pathway and decreased the expressions of steroidogenic enzymes. Hence, interaction with COX-2, NPY may affect the levels of PGF2α and PGE2 as well as impact the proliferation of granulosa cells in ovaries, thus further reducing the luteal formation, and promoting luteal structural and functional regression, as well as the ovarian steroidogenesis following EA treatment. EA treatment could be an option for preventing OHSS in ART. Copyright © 2018 Elsevier Inc. All rights reserved.

  1. Endocrine and molecular control of luteal and placental function in dogs: a review.

    Kowalewski, M P


    In the domestic dog (Canis familiaris), the corpus luteum (CL) is the only source of progesterone (P4) in non-pregnant and pregnant animals. The progesterone secretion profiles are almost identical in both conditions until the last third of the luteal phase when the gradual P4 decline turns into a steep drop in pregnant bitches, indicating the onset of parturition. Consequently, the length of the CL-phase in non-pregnant dogs exceeds the luteal lifespan in pregnant animals. The canine CL-function is regulated by many species-specific regulatory mechanisms, the most intriguing of which is the reported independence of gonadotropic support during the first third of dioestrus. Recently, PGE2 has been proposed as one of the most important luteotropic factors acting locally during this time, but afterwards prolactin (PRL) appears to be the main luteotropic factor. Luteal regression/luteolysis occurs, however, in spite of an increased gonadotropic support. Lately, by demonstrating the expression of PRL-receptor (PRLr), a new insight into possible regulatory mechanisms has indicated that the supply of P4 could be controlled upstream of the steroidogenic machinery at the level of PRLr expression and/or function, subsequently leading to the functional suppression of the steroidogenic machinery. An endogenous source of a luteolytic agent is apparently lacking, implicating the luteal regression in non-pregnant bitches as a passive, degenerative process even if the PGF2α-receptor is constitutively expressed in canine CL. This is in contrast to pregnant dogs in which prepartum luteolysis seems to be an active process of CL destruction by PGF2α of utero/placental origin targeting the luteal PGF2α-receptor. © 2012 Blackwell Verlag GmbH.

  2. Role of P2X7 on steroid synthesis in murine luteal cells

    Chunping Zhang


    Full Text Available The extracellular adenosine triphosphate (ATP regulates different cellular functions through activating purinergic receptors as a signalling molecule or neurotransmitter. P2X7 is highly expressed in murine small luteal cells. In this study, murine luteal cells were cultured in vitro and treated with P2X7 agonists – ATP and 2′(3′-O-(4-benzoyl-benzoyl-adenosine 50-triphosphate (BzATP and with P2X7 antagonist – brilliant blue G (BBG. We found that ATP and BzATP increased the production of progesterone and had no influence on the production of estradiol. BBG reversed the effect of BzATP and ATP. Further studies demonstrated that ATP and BzATP promoted the expression of CYP11A. These results revealed that P2X7 receptor activation is involved in the steroid synthesis in corpus luteum.

  3. Involvement of microtubules in lipoprotein degradation and utilization for steroidogenesis in cultured rat luteal cells

    Rajan, V.P.; Menon, K.M.


    Cells isolated from superovulated rat ovaries metabolize low density lipoprotein (LDL) and high density lipoprotein (HDL) of human or rat origin and use the lipoprotein-derived cholesterol as a precursor for progesterone production. Under in vitro conditions, both lipoproteins are internalized and degraded in the lysosomes, although degradation of HDL is of lower magnitude than that of LDL. In this report we have examined the role of cellular microtubules in the internalization and degradation of human LDL and HDL in cultured rat luteal cells. The microtubule depolymerizing agents colchicine, podophyllotoxin, vinblastine, and nocodazole as well as taxol, deuterium oxide, and dimethyl sulfoxide, which are known to rapidly polymerize cellular tubulin into microtubules, were used to block the function of microtubules. When these antimicrotubule agents were included in the incubations, degradation of the apolipoproteins of [ 125 I]iodo-LDL and [ 125 I]iodo-HDL by the luteal cells was inhibited by 50-85% compared to untreated control values. Maximum inhibitory effects were observed when the cells were preincubated with the inhibitor for at least 4 h at 37 C before treatment with the labeled lipoprotein. Lipoprotein-stimulated progesterone production by luteal cells was also inhibited by 50% or more in the presence of antimicrotubule agents. However, basal and hCG-stimulated progesterone production were unaffected by these inhibitors. The binding of [ 125 I]iodo-LDL and [ 125 I]iodo-HDL to luteal cell plasma membrane receptors was not affected by the microtubule inhibitors. Although binding was unaffected and degradation was impaired in the presence of the inhibitors, there was no detectable accumulation of undegraded lipoprotein within the cells during the 24 h of study

  4. Quantitative comparison of luteal histology in the rat and rabbit: changes from mid- to late gestation.

    Dharmarajan, A M; Bruce, N W; Meyer, G T


    Progesterone secretion by the corpora lutea (CL) of rats and rabbits declines from a peak, at about Day 16 of gestation, to near term (Day 22 rats and 28 rabbits). However there are major differences between the two species in CL growth and blood flow over this period. In the present work quantitative histological measurements were made of CL at these stages to examine the accompanying structural changes. Eight rats and five rabbits were examined at each stage: standard morphometric techniques were used. There was gross discrepancy between the two species in the histology of their CL at peak secretory activity. Although the proportions of the major tissue components were similar, the rabbit luteal cell (52 pl) was five times larger than that in the rat (9 pl). There was substantially less vascular and interstitial space in the rabbit, all characteristics which might affect transport processes between luteal cell cytoplasm and blood. Over the period examined, there was no change in CL volume in the rat but a 37% reduction in the rabbit due to loss of luteal cells. The vascular space in the rat, however, was reduced, whereas that in the rabbit declined only in proportion to the overall decrease in CL volume. These results show that structurally there is a substantial difference in patterns of early regression between the two species which reflect different mechanisms involved.

  5. Comparison between two forms of vaginally administered progesterone for luteal phase support in assisted reproduction cycles.

    Geber, Selmo; Moreira, Ana Carolina Ferreira; de Paula, Sálua Oliveira Calil; Sampaio, Marcos


    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.

  7. The relationship between serum adiponectin and postpartum luteal activity in high-producing dairy cows.

    Kafi, Mojtaba; Tamadon, Amin; Saeb, Mehdi


    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

  8. Simulated conditions of microgravity suppress progesterone production by luteal cells of the pregnant rat

    Bhat, G. K.; Yang, H.; Sridaran, R.


    The purpose of this study was to assess whether simulated conditions of microgravity induce changes in the production of progesterone by luteal cells of the pregnant rat ovary using an in vitro model system. The microgravity environment was simulated using either a high aspect ratio vessel (HARV) bioreactor with free fall or a clinostat without free fall of cells. A mixed population of luteal cells isolated from the corpora lutea of day 8 pregnant rats was attached to cytodex microcarrier beads (cytodex 3). These anchorage dependent cells were placed in equal numbers in the HARV or a spinner flask control vessel in culture conditions. It was found that HARV significantly reduced the daily production of progesterone from day 1 through day 8 compared to controls. Scanning electron microscopy showed that cells attached to the microcarrier beads throughout the duration of the experiment in both types of culture vessels. Cells cultured in chamber slide flasks and placed in a clinostat yielded similar results when compared to those in the HARV. Also, when they were stained by Oil Red-O for lipid droplets, the clinostat flasks showed a larger number of stained cells compared to control flasks at 48 h. Further, the relative amount of Oil Red-O staining per milligram of protein was found to be higher in the clinostat than in the control cells at 48 h. It is speculated that the increase in the level of lipid content in cells subjected to simulated conditions of microgravity may be due to a disruption in cholesterol transport and/or lesions in the steroidogenic pathway leading to a fall in the synthesis of progesterone. Additionally, the fall in progesterone in simulated conditions of microgravity could be due to apoptosis of luteal cells.

  9. Impact of peak/mid luteal estradiol on pregnancy outcome after intracytoplasmic sperm injection

    Rehman, R.; Hussain, Z.; Zahir, H.


    Objective: To compare peak to mid estradiol ratio with the probability of successful conception after intra-cytoplasmic sperm injection. Method: The quasi-experimental study was conducted in an infertility clinic at Islamabad from June 2010 till August 2011, and comprised couples subjected to intra-cytoplasmic sperm injection. Down-regulation of ovaries was followed by calculated stimulation, ovulation induction, oocytes retrieval, intra cytoplasmic sperm injection, in vitro maturation of embryos and finally blastocysts transfer. Serum estradiol was measured by enzyme-linked immunosorbent assay on ovulation induction day and the day of embryo transfer. Failure of procedure was detected by beta human chorionic gonadotropin 5-25mIU/ml (Group I; non-pregnant). Females with beta human chorionic gonadotropin>25mIU/ml and no cardiac activity after 4 weeks of transfer were placed in Group II (pre-clinical abortion), and confirmation of foetal heart in the latter comprised Group III (clinical pregnancy). Data was analysed using SPSS 15. Results: Of the 323 couples initially enrolled, embryo transfer was carried out in 282(87.3%) females. Clinical pregnancy was achieved in 101(36%) of the cases, while 61(21.63%) had pre-clinical abortion, and 120(42%) remained non-pregnant. The peak/mid-luteal estradiolratio was low (2.3) in patients who had high oocyte maturity (p=0.001) and fertilisation rate (p=0.003) compared to non-pregnant patients with high peak/mid-luteal estradiolratio (2.56). Conclusion: High peak estradiol with maintenance of optimal levels in mid-luteal phase is required for implantation of fertilised ovum and accomplishment of clinical pregnancy. (author)

    The objectives of the present study were to investigate the effects of vascular endothelial growth factor (VEGF) on progesterone (P4) synthesis in cultured luteal cells from different stages of the estrous cycle and on expression of steroidogenic acute regulatory protein (STARD1), cytochrome P450 cholesterol side chain cleavage (CYP11A1) and 3β-hydroxysteroid dehydrogenase (HSD3B), antiapoptotic gene PCNA, and proapoptotic gene BAX in luteal cells obtained from mid-luteal phase (MLP) of estrous cycle in buffalo. Corpus luteum samples from the early luteal phase (ELP; day 1st-4th; n=4), MLP (day 5th-10th; n=4), and the late luteal phase (LLP; day 11th-16th; n=4) of oestrous cycle were obtained from a slaughterhouse. Luteal cell cultures were treated with VEGF (0, 1, 10 and 100 ng/ml) for 24, 48 and 72h. Progesterone was assessed by RIA, while mRNA expression was determined by quantitative real-time PCR (qRT-PCR). Results indicated a dose- and time-dependent stimulatory effect of VEGF on P4 synthesis and expression of steroidogenic enzymes. Moreover, VEGF treatment led to an increase in PCNA expression and decrease in BAX expression. In summary, these findings suggest that VEGF acts locally in the bubaline CL to modulate steroid hormone synthesis and cell survivability, which indicates that this factor has an important role as a regulator of CL development and function in buffalo.

    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.

  12. Lower peripheral circulation in eumenorrheic young women with premenstrual symptoms

    Tatsumi Noriyuki


    Full Text Available Abstract Background A majority of women from all cultures and socioeconomic levels experience diverse psychosomatic and behavioral symptoms premenstrually, a phenomenon commonly termed premenstrual syndrome, although symptoms and discomfort levels vary from woman to woman. The underlying pathological mechanisms of premenstrual syndrome remain unknown; however, altered function or even slight disorder of the blood circulation system, which contributes to the orchestrations of the human internal environment, could cause bio-psychological changes leading to complaints and ultimately compromising a woman's overall health. The present study, therefore, investigates to what extent and how the menstrual cyclicity of peripheral circulation is associated with premenstrual symptomatology. Methods Twenty-one eumenorrheic young women participated in this study. All subjects were investigated during the follicular and late luteal phases. Cycle phase was determined by the onset of menstruation and oral temperature and was verified by concentrations of ovarian hormones, estrone, and pregnanediol in a urine sample taken early in the morning. Peripheral circulation was evaluated with the Astrim (Sysmex, Kobe, a portable non-invasive monitoring device using the principle of near-infrared spectroscopy, which calculates the venous oxygenation index (VOI based on the ratio of light absorption of oxyhemoglobin and deoxyhemoglobin, a proven reliable indicator of peripheral blood circulation. The Menstrual Distress Questionnaire was applied to measure physical, emotional, and behavioral symptoms accompanying the menstrual cycle of the subjects. Results The oral temperature and urinary ovarian hormones adjusted for creatinine significantly increased in the late luteal phase in all subjects. While 10 subjects experienced no symptoms during the menstrual cycle, 11 subjects had apparent physical and psychological discomfort in the late luteal phase. We found that VOI

  13. Thermodynamic modeling of phase relations and metasomatism in shear zones

    Goncalves, P.; Oliot, E.; Marquer, D.


    Ductile shear zones have been recognized for a long time as privileged sites of intense fluid-rock interactions in the crust. In most cases they induce focused changes in mineralogy and bulk chemical composition (metasomatism) which in turn may control the deformation and fluid-migration processes. Therefore understanding these processes requires in a first step to be able to model phase relations in such open system. In this contribution, emphasizes in placed on metasomatic aspects of the problem. Indeed , in many ductile shear zones reported in metagranites, deformation and fluid-rock interactions are associated with gain in MgO and losses of CaO and Na2O (K2O is also a mobile component but it can be either gained or lost). Although the mineralogical consequences of this so-called Mg-metasomatism are well-documented (replacement of K-feldspar into phengite, breakdown of plagioclase into ab + ep, crystallization of chlorite), the origin of this coupled mass-transfer is still unknown. We have performed a forward modeling of phase relationships using petrogenetic grids and pseudosections that consider variations in chemical potential (μ) of the mobile elements (MgO, CaO, Na2O). Chemical potential gradients being the driving force of mass transfer, μ-μ diagrams are the most appropriate diagrams to model open systems where fluid-rock interactions are prominent. Chemical potential diagrams are equivalent to activity diagrams but our approach differs from previous work because (1) solid solutions are taken into account (2) phase relations are modeled in a more realistic chemical system (Na2O-CaO-K2O-FeO-MgO-Al2O3-SiO2-H2O) and (3) the use of pseudosections allows to predict changes of the mineralogy (modes, composition) for the specific bulk composition studied. A particular attention is paid to the relationships between component concentrations and chemical potentials, which is not obvious in multi-component system. The studied shear zone is located in the Grimsel

    Bäckström, T.; Haage, D.; Löfgren, M.; Johansson, I. M.; Strömberg, J.; Nyberg, S.; Andréen, L.; Ossewaarde, L.; van Wingen, G. A.; Turkmen, S.; Bengtsson, S. K.


    Some women have negative mood symptoms, caused by progestagens in hormonal contraceptives or sequential hormone therapy or by progesterone in the luteal phase of the menstrual cycle, which may be attributed to metabolites acting on the GABA-A receptor. The GABA system is the major inhibitory system

  15. Effect of duration of the GnRH agonists in the luteal phase in the outcome of assisted reproduction cycles.

    Geber, Selmo; Sampaio, Marcos


    The effect of long-acting GnRHa, in the luteal phase, during ART cycles varies from one patient to another. The aim of this study was to evaluate whether the effect of long-acting GnRHa in the luteal phase, in ART cycles, affects pregnancy rates according to the duration of its action in such phase. This is a retrospective study of 367 patients submitted to ovulation induction for in vitro fertilization/intracytoplasmic sperm injection procedures that used long-acting depot GnRHa for pituitary suppression. Patients were stratified according to the period of action of the agonist in the luteal phase: group 1, ≤ 6 days; group 2, 7 to 12 days; and group 3, >12 days. The following variables were analyzed: ovarian response, age, infertility causes and pregnancy rates. Group 1 (n = 53) had a mean age of 33.8 ± 4.55 years (23-44 years) and a pregnancy rate of 45.2%. In group 2 (n = 118), mean age was 33.7 ± 4.5 years (24-44 years) and the pregnancy rate was 38.9%. In group 3 (n = 196), mean age was 33.7 ± 4.4 years (23-43 years) and the pregnancy rate was 47.4%. Regardless of the duration of depot GnRHa action in the luteal phase, no significant association with pregnancy rates was found.

  16. Administration of single-dose GnRH agonist in the luteal phase in ICSI cycles: a meta-analysis

    Oliveira João


    Full Text Available Abstract Background The effects of gonadotrophin-releasing hormone agonist (GnRH-a administered in the luteal phase remains controversial. This meta-analysis aimed to evaluate the effect of the administration of a single-dose of GnRH-a in the luteal phase on ICSI clinical outcomes. Methods The research strategy included the online search of databases. Only randomized studies were included. The outcomes analyzed were implantation rate, clinical pregnancy rate (CPR per transfer and ongoing pregnancy rate. The fixed effects model was used for odds ratio. In all trials, a single dose of GnRH-a was administered at day 5/6 after ICSI procedures. Results All cycles presented statistically significantly higher rates of implantation (P Conclusions These findings demonstrate that the luteal-phase single-dose GnRH-a administration can increase implantation rate in all cycles and CPR per transfer and ongoing pregnancy rate in cycles with GnRH antagonist ovarian stimulation protocol. Nevertheless, by considering the heterogeneity between the trials, it seems premature to recommend the use of GnRH-a in the luteal phase. Additional randomized controlled trials are necessary before evidence-based recommendations can be provided.

  17. Cytokine production by natural killer lymphocytes in follicular and luteal phase of the ovarian cycle in humans

    Bouman, A.; Moes, H; Heineman, MJ; De Leij, LFMH; Faas, MM

    PROBLEM: The aim of this study was to test the hypothesis that, during luteal phase of the ovarian cycle, as compared with follicular phase, the cytokine productive capacity of peripheral natural killer (NK)-lymphocytes in humans is shifted towards a "Th2-type"-like response. METHOD OF STUDY:

  18. The impact of luteal phase support on endometrial estrogen and progesterone receptor expression: a randomized control trial

    Brezina Paul R


    Full Text Available Abstract Background To assess the impact of luteal phase support on the expression of estrogen receptor (ER alpha and progesterone receptors B (PR-B on the endometrium of oocyte donors undergoing controlled ovarian hyperstimulation (COH. Methods A prospective, randomized study was conducted in women undergoing controlled ovarian hyperstimulation for oocyte donation. Participants were randomized to receive no luteal support, vaginal progesterone alone, or vaginal progesterone plus orally administered 17 Beta estradiol. Endometrial biopsies were obtained at 4 time points in the luteal phase and evaluated by tissue microarray for expression of ER alpha and PR-B. Results One-hundred and eight endometrial tissue samples were obtained from 12 patients. No differences were found in expression of ER alpha and PR-B among all the specimens with the exception of one sample value. Conclusions The administration of progesterone during the luteal phase of COH for oocyte donor cycles, either with or without estrogen, does not significantly affect the endometrial expression of ER alpha and PR.

  19. Effects of cholesterol and cAMP on progesterone production in cultured luteal cells isolated from pseudopregnant cat ovaries.

    Arikan, Sevket; Yigit, Ayse Arzu


    The present study was designed to incubate luteal cells isolated from pseudopregnant cats and to investigate the effects of cholesterol and cAMP on luteal progesterone production. Corpora lutea were collected from the cats on days 10 and 15 of pseudopregnancy. Luteal cells were isolated from the ovaries by collagenase digestion. Steroidogenic luteal cells were stained for 3beta-hydroxysteroid dehydrogenase (3beta-HSD) activity. Cells (2 x 10(4)) staining positive for 3beta-HSD were cultured for up to 7 days. The cells were treated with 22(R)-hydroxycholesterol (22R-HC) and dibutyryl cyclic AMP (dbcAMP) on days 1, 3 and 7. Treatment of cells with 22R-HC resulted in a dose-dependent increase (pprogesterone production. When 22R-HC was used at a concentration of 10 microg/ml, it resulted in 2.7- and 5.1-fold increases in progesterone production on days 3 and 5, respectively. When the dose was doubled (20 microg/ml), treated cells produced four times more progesterone on days 3 and 7, and three times more on day 5. By day 7, progesterone production increased up to 9.1 times more than the control. Incubation of cells with both concentrations of dbcAMP (0.1 mM and 1 mM) resulted in significant stimulations of progesterone on days 5 and 7 (pProgesterone production was increased up to 2- and 2.9-fold of the control when cells were treated with lower concentration of dbcAMP (0.1 mM) on days 5 and 7, respectively. Incubation of cells with 1 mM concentrations of dbcAMP induced a 3.2-fold increase on day 5 and a 5-fold increase on day 7. In conclusion, a successful incubation was performed for long-life culturing of luteal cells collected from pseudopregnant cats. The method works well and allows for optimal growth and development of cells in the culture. The present study also demonstrated that incubating cat luteal cells with 22R-HC and dbcAMP induces a significant increase in luteal progesterone synthesis.

    Zhao, Wei; Liu, Yifeng; Xu, Peng; Wu, Yiqing; Chen, Kai; Guo, Xiaoyan; Zhang, Fan; Huang, Yun; Zhu, Linlin; Zhang, Runjv; Zhang, Dan


    Any benefit of oestradiol supplementation with progesterone for luteal support after fresh embryo transfer in in vitro fertilisation/intracytoplasmic sperm injection (IVF/ICSI) cycles remains controversial. In this study, we further addressed this question in cycles using gonadotropin-releasing hormone (GnRH) agonist for ovarian stimulation. A retrospective cohort study in a tertiary teaching and research hospital. A total of 1602 patients were given oestradiol valerate (E) in addition to progesterone (P) as luteal support. One thousand six hundred and two patients receiving progesterone alone were selected as the control group. Live birth rate. Secondary measures included clinical pregnancy rate, miscarriage rate and premature birth rate. Clinical pregnancy and live birth rates were similar for the P alone vs the P+E group. In cycles with oestradiol (E2) levels less than 5000 pmol/L on the day of hCG trigger, E supplementation resulted in a significantly higher live birth rate (23.44% vs 32.92%, OR = 1.60 [95% CI 1.05 to 2.46]). In cycles with oestradiol levels 5000 to 10 000 pmol/L on the day of hCG trigger, E supplementation did not increase the live birth rate (34.43% vs 35.42%, OR = 0.90 [95% CI 0.80 to 1.01]). In cycles with oestradiol levels over 10 000 pmol/L on the day of hCG trigger, the live birth rate was significantly lower (36.83% vs 31.37%, OR = 0.78 [95% CI 0.62 to 0.99]) and the premature birth rate was significantly higher (19.66% vs 28.73%,OR = 1.65 [95% CI 1.05 to 2.59]) in the E supplementation group. Any benefit of oestradiol supplementation for luteal phase support appears to correlate with the serum oestradiol level on the day of hCG trigger. Oestradiol supplementation is beneficial for improving live birth rate in cycles with oestradiol levels less than 5000 pmol/L, but is not recommended in cycles with oestradiol levels over 10 000 pmol/L. © 2018 John Wiley & Sons Ltd.

  1. [Vitex agnus castus extract in the treatment of luteal phase defects due to latent hyperprolactinemia. Results of a randomized placebo-controlled double-blind study].

    Milewicz, A; Gejdel, E; Sworen, H; Sienkiewicz, K; Jedrzejak, J; Teucher, T; Schmitz, H


    The efficacy of a Vitex agnus castus preparation (Strotan capsules) was investigated in a randomized double blind study vs. placebo. This clinical study involved 52 women with luteal phase defects due to latent hyperprolactinaemia. The daily dose was one capsule (20 mg) Vitex agnus castus preparation and placebo, respectively. Aim of the study was to prove whether the elevated pituitary prolactin reserve can be reduced and deficits in luteal phase length and luteal phase progesterone synthesis be normalized. Blood for hormonal analysis was taken at days 5-8 and day 20 of the menstrual cycle before and after three month of therapy. Latent hyperprolactinaemia was analysed by monitoring the prolactin release 15 and 30 min after i.v. injection of 200 micrograms TRH. 37 complete case reports (placebo: n = 20, verum: n = 17) after 3 month of therapy were statistically evaluated. The prolactin release was reduced after 3 months, shortened luteal phases were normalised and deficits in the luteal progesterone synthesis were eliminated. These changes were significant and occurred only in the verum group. All other hormonal parameters did not change with the exception of 17 beta-estradiol which rouse up in the luteal phase in patients receiving verum. Side effects were not seen, two women treated with the Vitex agnus castus preparation got pregnant. The tested preparation is thought to be an efficient medication in the treatment of luteal phase defects due to latent hyperprolactinaemia.

    Samarütel, Jaak; Waldmann, Andres; Ling, Katri; Jaakson, Hanno; Kaart, Tanel; Leesmäe, Andres; Kärt, Olav


    The objective was to compare the relationships between luteal activity and fertility, and relate these parameters to metabolic indices and body condition changes in multiparous Estonian Holstein cows on two commercial dairy farms under different management and levels of production and nutrition (higher, H, n=54 (71 lactations) and lower, L, n=39 (39 lactations)). For statistical analysis cows were categorized according to their milk progesterone (P4) profiles as follows: normal ovarian function; delayed start of cyclicity (DC) (interval from calving to first luteal response (P45 ng/ml up to and more than 50 d respectively, followed by regular cyclicity); cessation of luteal activity (prolonged interluteal interval, P4bodies, non-esterified fatty acids, total cholesterol) and aspartate aminotransferase, body condition scores (BCS) and fertility parameters between the two farms, and also fertility parameters between the farms within P4 categories. Differences in milk fat/protein ratio, ketone body levels and BCS indicated a deeper negative energy balance (NEB) during the first month after calving on farm L. On both farms nearly 50% of the recently calved dairy cows suffered from ovarian dysfunction during the post-partum period. Delayed start of cyclicity was the most prevalent abnormal P4 profile, 25% and 28% on farms H and L, respectively. Prolonged luteal activity accounted for one-third of atypical ovarian patterns on farm H, and cessation of luteal activity on farm L. On farm L, DC cows had lower BCS values from day 10 to day 90 after calving compared with normal cows (Pcows lost more BCS (1.2 units) during the 40 d after calving than normal resumption cows (0.75 units; P<0.05). On farm H with moderate NEB the delayed start of ovulation post partum did not impair subsequent reproductive performance.

  4. Progesterone production is affected by unfolded protein response (UPR) signaling during the luteal phase in mice.

    Park, Hyo-Jin; Park, Sun-Ji; Koo, Deog-Bon; Lee, Sang-Rae; Kong, Il-Keun; Ryoo, Jae-Woong; Park, Young-Il; Chang, Kyu-Tae; Lee, Dong-Seok


    We examined whether the three unfolded protein response (UPR) signaling pathways, which are activated in response to endoplasmic reticulum (ER)-stress, are involved in progesterone production in the luteal cells of the corpus luteum (CL) during the mouse estrous cycle. The luteal phase of C57BL/6 female mice (8 weeks old) was divided into two stages: the functional stage (16, 24, and 48 h) and the regression stage (72 and 96 h). Western blotting and reverse transcription (RT)-PCR were performed to analyze UPR protein/gene expression levels in each stage. We investigated whether ER stress affects the progesterone production by using Tm (0.5 μg/g BW) or TUDCA (0.5 μg/g BW) through intra-peritoneal injection. Our results indicate that expressions of Grp78/Bip, p-eIF2α/ATF4, p50ATF6, and p-IRE1/sXBP1 induced by UPR activation were predominantly maintained in functional and early regression stages of the CL. Furthermore, the expression of p-JNK, CHOP, and cleaved caspase3 as ER-stress mediated apoptotic factors increased during the regression stage. Cleaved caspase3 levels increased in the late-regression stage after p-JNK and CHOP expression in the early-regression stage. Additionally, although progesterone secretion and levels of steroidogenic enzymes decreased following intra-peritoneal injection of Tunicamycin, an ER stress inducer, the expression of Grp78/Bip, p50ATF6, and CHOP dramatically increased. These results suggest that the UPR signaling pathways activated in response to ER stress may play important roles in the regulation of the CL function. Furthermore, our findings enhance the understanding of the basic mechanisms affecting the CL life span. Copyright © 2014 Elsevier Inc. All rights reserved.

  5. Effect of Estradiol Prescribed during Luteal Phase of Art Cycles and Pregnancy Outcome

    M Karimzadeh


    Full Text Available Introduction: Implantation is one of the most important steps in ART cycles and it depends upon embryo and endometrial reception. Different protocols have been suggested for getting better endometrium. It seems estrogen increases the endometrial reception and pregnancy rate by inducing changes in the hormonal status. The aim of this study was to evaluate the effect of estradiol(E2 on luteal phase support and pregnancy rate in ART cycles Methods: This prospective randomized study was done in Yazd at the IVF center from March until December, 2002. 68 patients who had undergone IVF or ICSI were enrolled in the study. Exclusion criteria was age>40, endometriosis and ovarian hyper stimulation syndrome. Induction ovulation protocol was long suppression with GnRH analogues.After embryo transfer, patients were divided in two groups randomly. Both groups received 100mg progesterone IM daily from the transfer day. Estradiol valerate 2 mg/day was added from the 7th transfer day to progesterone in Group I and continued if the BhCG became positive. Abortion and malformations were measured in all patients. Data analyzed with SPSS 11.0 and P value <0.05 considered statistically significant. Results: Pregnancy rate in the 34 patients of estradiol group (group I was 26.5%which was significantly higher than 11.8 %( 4 cases in the other group (Pvalue=0.034. Abortion rate was higher in estradiol group (3 cases, but there was no abortion in the progesterone group(P=0.119. 2 cases of major fetal malformations were observed in E2 supplementation group (P=0.246 . Conclusions: E2 suplementation to progesterone in the luteal phase of ART cycles, especially in the long GnRH analogues causes higher endometrial receptivity and pregnancy rate.

  6. Factors related to declining luteal function in women during the menopausal transition.

    Santoro, N; Crawford, S L; Lasley, W L; Luborsky, J L; Matthews, K A; McConnell, D; Randolph, J F; Gold, E B; Greendale, G A; Korenman, S G; Powell, L; Sowers, M F; Weiss, G


    Reproductive hormones are incompletely characterized during the menopause transition (MT). Increased anovulation and decreased progesterone accompany progress through the MT. The Daily Hormone Study (DHS) of the Study of Women's Health Across the Nation (SWAN) included 848 women aged 43-53 yr at baseline who collected daily urine for one cycle or up to 50 d annually for 3 yr. LH, FSH, estrone conjugates, and pregnanediol glucuronide levels were assessed. Cycles were classified by presumed luteal (ovulatory) status and bleeding. Hormones were related to time in study, age, menopausal status, and selected variables. Ovulatory-appearing cycles declined from 80.9% at baseline to 64.7% by the third assessment (H3). Cycles presumed anovulatory and not ending with bleeding by 50 d (anovulatory/nonbleeding) increased from 8.4 to 24% by H3 and were associated with progress to early perimenopause [odds ratio (OR) = 2.66; confidence interval (CI) = 1.17-6.04] or late perimenopause (OR = 56.21; CI = 18.79-168.12; P school education (OR = 3.51; CI = 1.62-7.62). Anovulatory cycles ending with bleeding remained at about 10% from baseline to H3; compared with ovulatory cycles, they were associated with obesity (OR = 4.68; CI = 1.33-16.52) and more than high school education (OR = 2.12; CI = 1.22-3.69; P = 0.02). Serum estradiol in both the highest and lowest categories was associated with anovulatory/nonbleeding collections. Pregnanediol glucuronide decreased 6.6% for each year on study. Insulin sensitivity measures did not relate strongly to menstrual cycle hormones. Anovulation without bleeding represents progression of the MT. A small but detectable decrease in luteal progesterone excretion occurs as women progress through the MT.

  7. Leukocyte changes across menstruation, ovulation, and mid-luteal phase and association with sex hormone variation.

    Nowak, Judyta; Borkowska, Barbara; Pawlowski, Boguslaw


    Total leukocyte count (white blood cells-WBC) and the count of each subpopulation vary across the menstrual cycle, but results of studies examining the time and direction of these changes are inconsistent and methodologically flawed. Besides, no previous study focused on leukocyte count on the day of ovulation. Blood samples were obtained from 37 healthy and regularly cycling women aged 19.8-36.1 years. Samples were taken three times: during menstruation (M), ovulation (O), and in the mid-luteal phase (ML). WBC, neutrophils, lymphocytes, mixed cells, progesterone (P,) and estradiol (E) were measured in each of the three target phases of the cycle. Compared to menstruation, WBC (P = 0.002) and neutrophils (P < 0.001) increased around ovulation and remained stable in the mid-luteal phase, whereas lymphocyte and mixed cell counts did not change throughout the menstrual cycle. There were some correlations of sex hormone variation with leukocyte changes between M and O (positive for E and WBC, negative for P and WBC and for P and neutrophil count; P < 0.05), but not between O and ML. Peripheral leukocyte changes taking place in the second half of the cycle are already observable on the day of ovulation and they are associated with sex hormone variation. We speculate that these changes may lead to increased immune protection against pathogens at a time when fertilization and implantation typically occur. Am. J. Hum.

  8. Origin of the Nonsinusoidal current-phase relation of a superconducting bridge

    Sugahara, M.


    The current-phase relation of a long superconducting bridge is investigated with the use of the Aslamazov-Larkin model and the Ginzburg-Landau equation. The feedback effect of the supercurrent to the phase difference in the weak link is taken into consideration. The derived nonsinusoidal current-phase relation explains the experiments of Jackel et al. very well

  9. Comparison of the Efficacy of Two Vaginal Progesterone Formulations, Crinone 8% Gel and Utrogestan Capsules, Used for Luteal Support in Blastocyst Stage Embryo Transfers

    Li-Jung Wang


    Conclusion: Luteal phase support with Crinone 8% vaginal gel (90 mg daily resulted in better clinical pregnancy and implantation rates than Utrogestan vaginal capsules (200 mg, 4 times daily in IVF/ICSI–BT cycles.

  10. Age-related changes in luteal dynamics: preliminary associations with antral follicular dynamics and hormone production during the human menstrual cycle.

    Baerwald, Angela; Vanden Brink, Heidi; Hunter, Caitlin; Beuker, Denae; Lim, Hyun; Lee, Chel Hee; Chizen, Donna


    The aim of the study was to test the hypothesis that the development of luteal phase dominant follicles (LPDFs) as women age is associated with abnormal luteal function. Luteal and antral follicle diameter were quantified in ovulatory women of midreproductive age (MRA; 18-35 y; n = 9) and advanced reproductive age (ARA; 45-55 y; n = 16) every 1 to 3 days during one complete interovulatory interval. Blood was drawn at each visit and assayed for progesterone, estradiol, inhibin A, follicle-stimulating hormone, and luteinizing hormone. Luteal diameter and hormone profiles were compared within MRA and ARA women with versus without LPDFs. Luteal growth and regression profiles were similar in MRA women with typical versus no LPDFs (13.9, 14.8 mm; P > 0.1); however, luteal phase estradiol and progesterone were greater in MRA women with typical (91.1 ng/L, 8.81 μg/L) versus no (48.8 ng/L, 7.32 μg/L) LPDFs, respectively (LPDF effect, P < 0.1). In the ARA group, mean luteal diameter was lowest in women with atypical LPDFs (12.3 mm), greatest in those with typical LPDFs (16.0 mm), and moderate in those with no LPDFs (13.6 mm), (P < 0.1). Reduced luteal growth in ARA women with atypical versus typical and/or no LPDFs occurred simultaneously to greater luteal phase estradiol (199 vs 69.0, 78.4 ng/L) lower progesterone (7.38 vs 10.7, 13.8 ug/L), and lower inhibin A (36.3, 35.6, 51.2) (P < 0.1). The development of LPDFs as women age was associated with reduced luteal growth, greater estradiol, lower progesterone, and lower inhibin A. These findings provide preliminary evidence that variations in antral folliculogenesis contribute to luteal insufficiency during the menopausal transition.

  12. Luteal and placental function in the bitch: spatio-temporal changes in prolactin receptor (PRLr) expression at dioestrus, pregnancy and normal and induced parturition

    Hoffmann Bernd; Guscetti Franco; Boos Alois; Gram Aykut; Michel Erika; Kowalewski Mariusz P; Aslan Selim; Reichler Iris


    Abstract Background Endocrine mechanisms governing canine reproductive function remain still obscure. Progesterone (P4) of luteal origin is required for maintenance of pregnancy. Corpora lutea (CL) are gonadotrop-independent during the first third of dioestrus; afterwards prolactin (PRL) is the primary luteotropic factor. Interestingly, the increasing PRL levels are accompanied by decreasing P4 concentrations, thus luteal regression/luteolysis occurs in spite of an increased availability of g...

  13. A randomized trial of microdose leuprolide acetate protocol versus luteal phase ganirelix protocol in predicted poor responders.

    DiLuigi, Andrea J; Engmann, Lawrence; Schmidt, David W; Benadiva, Claudio A; Nulsen, John C


    We performed a randomized trial to compare IVF outcomes in 54 poor responder patients undergoing a microdose leuprolide acetate (LA) protocol or a GnRH antagonist protocol incorporating a luteal phase E(2) patch and GnRH antagonist in the preceding menstrual cycle. Cancellation rates, number of oocytes retrieved, clinical pregnancy rates (PR), and ongoing PRs were similar between the two groups. Copyright © 2011 American Society for Reproductive Medicine.

  14. Onset and duration of luteal activity postpartum and their effect on first insemination conception rate in lactating dairy cows.

    Hommeida, Abdelrahim; Nakao, Toshihiko; Kubota, Hirokazu


    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.

  15. Analysis of human mammary fibroadenoma by Ki-67 index in the follicular and luteal phases of menstrual cycle.

    Rego, M F; Navarrete, M A L H; Facina, G; Falzoni, R; Silva, R; Baracat, E C; Nazario, A C P


    Fibroadenoma is the most common benign mammary condition among women aged 35 or younger. Expression of Ki-67 antigen has been used to compare proliferative activity of mammary fibroadenoma epithelium in the follicular and luteal phases of the menstrual cycle. Ninety eumenorrheic women were selected for tumour excision; they were assigned to either of the two groups, according to their phase of menstrual cycle. At the end of the study, 75 patients with 87 masses were evaluated by epithelial cell Ki-67 expression, blind (no information given concerning group to which any lesion belonged). Both groups were found to be homogeneous relative to age, menarche, body mass index, previous gestation, parity, breastfeeding, number of fibroadenomas, family history of breast cancer and tabagism. Median tumour size was 2.0 cm and no relationship between proliferative activity and nodule diameter was observed. No typical pattern was observed in the expression of Ki-67 in distinct nodules of the same patient. Average values for expression of Ki-67 (per 1000 epithelial cells) in follicular and luteal phases were 27.88 and 37.88, respectively (P = 0.116). Our findings revealed that proliferative activities in the mammary fibroadenoma epithelium did not present a statistically significant difference in the follicular and luteal phases. The present study contributes to clarifying that fibroadenoma is a neoplasm and does not undergo any change in the proliferative activity during the menstrual cycle.

  16. Effect of anabolics on bovine granulosa-luteal cell primary cultures.

    Bartolomeo Biolatti


    Full Text Available Granulosa cell tumours are observed with increased frequency among calves slaughtered in Northern Italy. The use of illegal anabolics in breeding was taken into account as a cause of this pathology. An in vitro approach was used to detect the possible alterations of cell proliferation induced by anabolics on primary cultures of bovine granulosa-luteal cells. Cultures were treated with different concentrations of substances illegally used in cattle (17beta-estradiol, clenbuterol and boldione. Cytotoxicity was determined by means of MTT test, to exclude toxic effects induced by anabolics and to determine the highest concentration to be tested. Morphological changes were evaluated by means of routine cytology, while PCNA expression was quantified in order to estimate cell proliferation. Cytotoxic effects were revealed at the highest concentrations. The only stimulating effect on cell proliferation was detected in boldione treated cultures: after 48 h treated cells, compared to controls, showed a doubled expression of PCNA. In clenbuterol and 17beta-estradiol treated cells PCNA expression was similar to controls or even decreased. As the data suggest an alteration in cell proliferation, boldione could have a role in the early stage of pathogenesis of granulosa cell tumour in cattle.

  17. The cytoskeleton proteins and LH-regulated steroidogenesis in porcine luteal cells

    Gregoraszczuk, Ewa L.; Slomczynska, Maria


    The involvement of microtubules (MT) and microflilaments (MF) in LH-regulation of luteal cell stereoidogenesis was assessed at the middle stage of corpus luteum development. The influence microtubule- and microfilament-altering agents on basal and LH-stimulated progesterone (P4) production and secretion into the incubation medium was determined by RIA. LH-stimulated P4 production was 2.5 times higher than in the control cultures. Cytochalasis B (Cyt B) was without effect on basal P4 synthesis but increased the basal fraction of P4 secreted into the incubation medium, while colchicine (Col) increased both basal P4 synthesis and the fraction of P4 secreted into the incubation medium. LH-stimulated progesterone synthesis was reduced by Col, but the fraction secreted into the incubation medium increased. Cyt B had no effect on LH-stimulated synthesis but it decreased the fraction of P4 secreted into the incubation medium. Our findings demonstrate significant differences in the effect of Cyt B and Col on steroidogenesis in corpus luteum. We conclude that microtubules play an important role in the process of LH-stimulated P4 synthesis, while microfilaments act in the process of basal and LH-stimulated P4 secretion.

  18. Association of menstrual phase with smoking behavior, mood and menstrual phase-associated symptoms among young Japanese women smokers.

    Sakai, Hiroko; Ohashi, Kazutomo


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

  19. A new method for the experimental determination of three-phase relative permeabilities

    Perez Carrillo, Edgar Ricardo; Jose Francisco Zapata Arango; Santos Santos, Nicolas


    Petroleum reservoirs under primary, secondary or tertiary recovery processes usually experience simultaneous flow of three fluids phases (oil, water and gas). Reports on some mathematical models for calculating three-phase relative permeability are available in the Literature. Nevertheless, many of these models were designed based on certain experimental conditions and reservoir rocks and fluids. Therefore, special care has to be taken when applying them to specific reservoirs. At the laboratory level, three-phase relative permeability can be calculated using experimental unsteady-state or steady state methodologies. This paper proposes an unsteady-state methodology to evaluate three-phase relative permeability using the equipment available at the petrophysical analysis Laboratory of the Instituto Colombiano del Petroleo (ICP) of Ecopetrol S.A. Improvements to the equipment were effected in order to achieve accuracy in the unsteady-state measurement of three-phase relative permeability. The target of improvements was directed toward to the attainment of two objectives:1) the modification of the equipment to obtain more reliable experimental data and 2) the appropriate interpretation of the data obtained. Special attention was given to the differential pressure and uncertainty measurement in the determination of fluid saturation in the rock samples. Three experiments for three-phase relative permeability were conducted using a sample A and reservoir rock from the Colombian Foothills. Fluid tests included the utilization of synthetic brine, mineral oil, reservoir crude oil and nitrogen. Two runs were conducted at the laboratory conditions while one run was conducted at reservoir conditions. Experimental results of these tests were compared using 16 mathematical models of three-phase relative permeability. For the three-phase relative permeability to oil, the best correlations between experimental data and tests using Blunt, Hustad Hasen, and Baker's models were

    Full Text Available Background: Based on the facts known from embryology, rapid endometrial growth during late luteal phase of the cycle could be expected. In this research, we sought to establish if normal intrauterine pregnancy could be confirmed before gestational sac vizualization, by trans- vaginal ultrasound and hormonal tests. The primary hypothesis was that the endometrial thickness and/or volume in the luteal phase of the cycle, in cycles resulting in normal intra- uterine pregnancy, is significantly different compared to non-conception cycles. We also hypothesized that endometrial thickness and/or volume are different in cycles resulting in normal intrauterine pregnancy compared to cycles resulting in abnormal pregnancy, namely biochemical and ectopic pregnancy, and spontaneous abortion. Additionally, next to endometrial volumes, we decided to measure the endometrium in three planes (thick- ness, length and width, to see if the hypothesized endometrial volume differences could be approximated by this simple surrogate technique, which is available in most parts of the world. Methods: This was a prospective observational study of women enrolled in an assisted reproduction program. Patients were stimulated with standard stimulation protocols. The oocyte retrieval was performed 36 hours after the hCG administration and the embryo was transferred 3 or 5 days later. Patients were first seen on day 20–24 of the cycle , and then on day 27–30 of the cycle. A blood sample was taken, and 3D transvaginal ultrasound was done. Following the completion of study visits, patients with a positive HCG test received phone call check- ups until week 12 of pregnancy, and were stratified according to pregnancy outcome. Results: 80 subjects signed the informed consent form. 4 patients had the IUI in the stimulated cycle, one had ET in spontaneous cycle, and 74 patients had undergone IVF/ET in the stimulated cycle. 63 patients in the stimulated cycles completed the study and

  1. Effect of LH and prolactin on steroid secretion by perifused luteal tissue from pregnant gilts with induced hypoprolactinemia or after passive immunoneutralization of LH

    Szafranska, B.; Przala, J.; Grazul-Bilska, A.


    The study was performed using luteal tissue obtained from 24 pregnant gilts. Group 1 was treated with bromocriptine (BR) from 37th to 42nd day of day of pregnancy. Group 2 was treated with homologous anti-pLH serum from 37th to 42nd day of pregnancy. Group 3 was given BR from 67th to 72nd day of gestation. Group 4 received anti-pLH serum from 67th to 72nd day of pregnancy. The effect of exogenous LH or prolactin (100 ng/ml) on secretion of progesterone (P 4 ) and estradiol (E 2 ) by luteal tissue was studied using perfusion technique. Prolactin caused a significant (P 4 secretion by luteal tissue from gilts in groups 1 and 4. Both LH and prolactin decreased (P 4 and E 2 secretion by luteal tissue from gilts from groups 4 and 2, respectively. The results demonstrate that both LH and prolactin have a regulatory role in steroid secretion by luteal tissue of gilts in the mid- and late period of pregnancy. (author). 28 refs, 2 figs

  2. GnRH Agonist Trigger and LH Activity Luteal Phase Support versus hCG Trigger and Conventional Luteal Phase Support in Fresh Embryo Transfer IVF/ICSI Cycles—A Systematic PRISMA Review and Meta-analysis

    Thor Haahr


    Full Text Available IntroductionThe use of GnRH agonist (GnRHa for final oocyte maturation trigger in oocyte donation and elective frozen embryo transfer cycles is well established due to lower ovarian hyperstimulation syndrome (OHSS rates as compared to hCG trigger. A recent Cochrane meta-analysis concluded that GnRHa trigger was associated with reduced live birth rates (LBRs in fresh autologous IVF cycles compared to hCG trigger. However, the evidence is not unequivocal, and recent trials have found encouraging reproductive outcomes among couples undergoing GnRHa trigger and individualized luteal LH activity support. Thus, the aim was to compare GnRHa trigger followed by luteal LH activity support with hCG trigger in IVF patients undergoing fresh embryo transfer.Material and methodsWe conducted a systematic review and meta-analysis of randomized trials published until December 14, 2016. The population was infertile patients submitted to IVF/ICSI cycles with GnRH antagonist cotreatment who underwent fresh embryo transfer. The intervention was GnRHa trigger followed by LH activity luteal phase support (LPS. The comparator was hCG trigger followed by a standard LPS. The critical outcome measures were LBR and OHSS rate. The secondary outcome measures were number of oocytes retrieved, clinical and ongoing pregnancy rates, and miscarriage rates.ResultsA total of five studies met the selection criteria comprising a total of 859 patients. The LBR was not significantly different between the GnRHa and hCG trigger groups (OR 0.84, 95% CI 0.62, 1.14. OHSS was reported in a total of 4/413 cases in the GnRHa group compared to 7/413 in the hCG group (OR 0.48, 95% CI 0.15, 1.60. We observed a slight, but non-significant increase in miscarriage rate in the GnRHa triggered group compared to the hCG group (OR 1.85; 95% CI 0.97, 3.54.ConclusionGnRHa trigger with LH activity LPS resulted in comparable LBRs compared to hCG trigger. The most recent trials reported LBRs close to unity

  3. Phase characteristics of rheograms. Original classification of phase-related changes of rheos

    Mikhail Y. Rudenko


    Full Text Available The phase characteristics of a rheogram are described in literature in general only. The existing theory of impedance rheography is based on an analysis of the form of rheogram envelopes, but not on the phase-related processes and their interpretation according to the applicable laws of physics. The aim of the present paper is to describe the phase-related characteristics of a rheogram of the ascending aorta. The method of the heart cycle phase analysis has been used for this purpose. By synchronizing an ECG of the aorta and a rheogram, an analysis of specific changes in the aorta blood filling in each phase is provided. As a result, the phase changes of a rheogram associated with the ECG phase structure are described and tabulated for first time. The author hereof offers his own original classification of the phase-related changes of rheograms.

    These data and analyses support the research article "Experimental study on phase relations in the Ce-Fe-Sb ternary system" Zhu et al. (2017) [1]. The data and analyses presented here include the experimental results of XRD, SEM and EPMA for the determination of the whole liquidus projection and the isothermal section at 823 K in the Ce-Fe-Sb system. All the results enable the understanding of the constituent phases and the solidification processes of the as-cast alloys as well as the phase relations and the equilibrium regions at 823 K in the Ce-Fe-Sb ternary system over the entire composition.

  5. Changes in insulin-like growth factor-binding protein-3 messenger ribonucleic acid in endothelial cells of the human corpus luteum: a possible role in luteal development and rescue.

    Fraser, H M; Lunn, S F; Kim, H; Duncan, W C; Rodger, F E; Illingworth, P J; Erickson, G F


    In the human menstrual cycle, extensive angiogenesis accompanies luteinization; and the process is physiologically important for corpus luteum (CL) function. During luteolysis, the vasculature collapses, and the endothelial cells die. In a conceptual cycle, the CL persists both functionally and structurally beyond the luteoplacental shift. Although luteal rescue is not associated with increased angiogenesis, endothelial survival is extended. Despite the central role of the luteal vasculature in fertility, the mechanisms regulating its development and demise are poorly understood. There is increasing evidence that insulin-like growth factors (IGFs) and their binding proteins (IGFBPs) may be important effectors of luteal function. Here, we have found that IGFBP-3 messenger RNA is expressed in the endothelium of the human CL and that the levels of message change during luteal development and rescue by human CG. The signal was strong during the early luteal phase, but it showed significant reduction during the mid- and late luteal phases. Interestingly, administration of human CG caused a marked increase in the levels of IGFBP-3 messenger RNA in luteal endothelial cells that was comparable to that observed during the early luteal phase. We conclude that endothelial cell IGFBP-3 expression is a physiological property of the CL of menstruation and pregnancy. These observations raise the intriguing possibility that the regulated expression of endothelial IGFBP-3 may play a role in controlling angiogenesis and cell responses in the human CL by autocrine/paracrine mechanisms.

  6. Current-phase relation of a Bose-Einstein condensate flowing through a weak link

    Piazza, F.; Smerzi, A.; Collins, L. A.


    We study the current-phase relation of a Bose-Einstein condensate flowing through a repulsive square barrier by solving analytically the one-dimensional Gross-Pitaevskii equation. The barrier height and width fix the current-phase relation j(δφ), which tends to j∼cos(δφ/2) for weak barriers and to the Josephson sinusoidal relation j∼sin(δφ) for strong barriers. Between these two limits, the current-phase relation depends on the barrier width. In particular, for wide-enough barriers, we observe two families of multivalued current-phase relations. Diagrams belonging to the first family, already known in the literature, can have two different positive values of the current at the same phase difference. The second family, new to our knowledge, can instead allow for three different positive currents still corresponding to the same phase difference. Finally, we show that the multivalued behavior arises from the competition between hydrodynamic and nonlinear-dispersive components of the flow, the latter due to the presence of a soliton inside the barrier region.

    Uranyl mineral paragenesis at Nopal I is an analog of spent fuel alteration at Yucca Mountain. Petrographic studies suggest a variety of possible hydrothermal conditions for uranium mineralization at Nopal I. Calculated equilibrium phase relations among uranyl minerals show uranophane stability over a broad range of realistic conditions and indicate that uranyl mineral variety reflects persistent chemical potential heterogeneity.

    Teplitz MA


    Full Text Available The aim of this study was to establish and characterize the porcine luteal cells (PLC culture for the subsequent coculture with porcine COC. The final purpose is to promote the oocyte maturation. The PLC was established using corpora lutea obtained from slaughterhouse ovaries. Corpora lutea were dissected and luteal tissue submitted to a mechanical and enzymatic digestion with collagenase IV. The cell suspension was filtered and centrifuged and the cells obtained were diluted in 15 mL of DMEM-F12 supplemented media. Diluted cells were seeded in 3 culture flasks T25, staying in a controlled environment and changing the medium every 2 days. For the analysis and characterization, the cells were assessed by the Nile red staining to detect intracellular lipids, immunocytochemistry (ICC for 3β-hydroxy steroid dehidrogenase (3β-HSD and ELISA for P4 determination. We observed the presence of lipid intracellular droplets. Also, we observed an increase of P4 concentration at 48, 96 y 144 h of primary culture and almost all the cells were positive to the ICC evaluation for 3β-HSD, showing the steroidogenic capacity of the culture cells.

  11. Transcriptome analysis reveals differences in mechanisms regulating cessation of luteal function in pregnant and non-pregnant dogs.

    Zatta, Sophie; Rehrauer, Hubert; Gram, Aykut; Boos, Alois; Kowalewski, Mariusz Pawel


    In the domestic dog, corpora lutea (CL) are the only source of progesterone (P4), both in pregnant and non-pregnant cycles because there is no placental steroidogenesis. The absence of an endogenous luteolysin in absence of pregnancy results in long-lasting physiological pseudopregnancy, strongly contrasting with the acute luteolysis observed prepartum. The underlying biological mechanisms and the involvement of P4 signalling remain, however, not fully understood. Therefore, here, next-generation sequencing (RNA-Seq) was performed on CL from the late luteal phase and compared with normally luteolyzing CL collected at the prepartum P4 decrease. The contrast "luteal regression over luteolysis" yielded 1595 differentially expressed genes (DEG). The CL in late luteal regression were predominantly associated with functional terms linked to extracellular matrix (p = 5.52e-05). Other terms related to transcriptional activity (p = 2.45e-04), and steroid hormone signalling (p = 2.29e-04), which were more highly represented in late regression than during luteolysis. The prepartum luteolysis was associated with immune inflammatory responses (p = 2.87e-14), including acute-phase reaction (p = 4.10e-06). Immune system-related events were also more highly represented in CL derived from normal luteolysis (p = 7.02e-04), compared with those from dogs in which luteolysis was induced with an antigestagen (1480 DEG in total). Additionally, the withdrawal of P4 at mid-gestation resulted in 92 DEG; over-represented terms enriched in antigestagen-treated dogs were related to the inflammatory response (p = 0.005) or response to IL1 (p = 7.29e-05). Terms related to proliferation, e.g., centrosome organization (p = 0.002) and steroid metabolic processes (p = 0.001), prevailed at mid-gestation. Thereby, our results revealed the nature of luteotropic effects of P4 within canine CL. It appears that, even though they result in diminished steroidogenic output, the effect of

  13. Asymmetric current-phase relation due to spin-orbit interaction in semiconductor nanowire Josephson junction

    Yokoyama, Tomohiro; Eto, Mikio [Faculty of Science and Technology, Keio University, 3-14-1 Hiyoshi, Kohoku-ku, Yokohama 223-8522 (Japan); Nazarov, Yuli V. [Kavli Institute of Nanoscience, Delft University of Technology, Lorentzweg 1, 2628 CJ Delft, The Netherlands (Netherlands)


    We theoretically study the current-phase relation in semiconductor nanowire Josephson junction in the presence of spin-orbit interaction. In the nanowire, the impurity scattering with strong SO interaction is taken into account using the random matrix theory. In the absence of magnetic field, the Josephson current I and phase difference φ between the superconductors satisfy the relation of I(φ) = –I(–φ). In the presence of magnetic field along the nanowire, the interplay between the SO interaction and Zeeman effect breaks the current-phase relation of I(φ) = –I(–φ). In this case, we show that the critical current depends on the current direction, which qualitatively agrees with recent experimental findings.

  14. Luteal and placental function in the bitch: spatio-temporal changes in prolactin receptor (PRLr expression at dioestrus, pregnancy and normal and induced parturition

    Hoffmann Bernd


    Full Text Available Abstract Background Endocrine mechanisms governing canine reproductive function remain still obscure. Progesterone (P4 of luteal origin is required for maintenance of pregnancy. Corpora lutea (CL are gonadotrop-independent during the first third of dioestrus; afterwards prolactin (PRL is the primary luteotropic factor. Interestingly, the increasing PRL levels are accompanied by decreasing P4 concentrations, thus luteal regression/luteolysis occurs in spite of an increased availability of gonadotropic support. PRL acts through its receptor (PRLr, the expression of which has not yet been thoroughly investigated at the molecular and cellular level in the dog. Methods The expression of PRLr was assessed in CL of non-pregnant dogs during the course of dioestrus (days 5, 15, 25, 35, 45, 65 post ovulation; p.o. as well as in CL, the utero/placental compartments (Ut/Pl and interplacental free polar zones (interplacental sites from pregnant dogs during the pre-implantation, post-implantation and mid-gestation period of pregnancy and during the normal and antigestagen-induced luteolysis. Expression of PRLr was tested by Real Time PCR, immunohistochemistry and in situ hybridization. Results In non-pregnant CL the PRLr expression was significantly upregulated at day 15 p.o. and decreased significantly afterwards, towards the end of dioestrus. CL of pregnancy showed elevated PRLr expression until mid gestation while prepartal downregulation was observed. Interestingly, placental but not interplacental expression of PRLr was strongly time-related; a significant upregulation was observed towards mid-gestation. Within the CL PRLr was localized to the luteal cells; in the Ut/Pl it was localized to the fetal trophoblast and epithelial cells of glandular chambers. Moreover, in mid-pregnant animals treated with an antigestagen, both the luteal and placental, but not the uterine PRLr were significantly downregulated. Conclusions The data presented suggest that the

In non-pregnant CL the PRLr expression was significantly upregulated at day 15 p.o. and decreased significantly afterwards, towards the end of dioestrus. CL of pregnancy showed elevated PRLr expression until mid gestation while prepartal downregulation was observed. Interestingly, placental but not interplacental expression of PRLr was strongly time-related; a significant upregulation was observed towards mid-gestation. Within the CL PRLr was localized to the luteal cells; in the Ut/Pl it was localized to the fetal trophoblast and epithelial cells of glandular chambers. Moreover, in mid-pregnant animals treated with an antigestagen, both the luteal and placental, but not the uterine PRLr were significantly downregulated. The data presented suggest that the luteal provision of P4 in both pregnant and non-pregnant dogs

  16. Growth Hormone Supplementation in the Luteal Phase Before Microdose GnRH Agonist Flare Protocol for In Vitro Fertilization.

    Dunne, Caitlin; Seethram, Ken; Roberts, Jeffrey


    Growth hormone (GH) acts in both early and late follicular development to stimulate the proliferation and differentiation of granulosa cells and to increase the production of estradiol in animal and human ovaries. Investigators have therefore explored GH supplementation to improve outcomes in women undergoing in vitro fertilization, with the greatest interest in women with diminished ovarian reserve. Recent meta-analyses indicate that GH supplementation can be beneficial for poor responders undergoing IVF. In most studies, GH has been given concomitantly with gonadotropins during the follicular phase; this may not be optimal, since follicular recruitment begins during the preceding luteal phase. We therefore wished to examine the effect of GH supplementation in the luteal phase before controlled ovarian stimulation (COH) with a microdose GnRH agonist flare (MDF) protocol in women undergoing in vitro fertilization. We performed a retrospective matched case-control study of patients undergoing treatment at a private IVF facility between June 2012 and July 2013. Patients identified as poor responders to COH were offered adjuvant GH treatment as part of their ovarian stimulation regimen. The patients in the experimental group chose to take GH, 3.33 mg daily by subcutaneous injection for 14 days, before starting COH. All patients had an MDF stimulation protocol using 450 IU of follicle stimulating hormone (FSH) daily. A total of 42 women were included in the study. There were 14 women in the experimental group (GH) and 28 controls (C) matched for age, BMI, and day 3 FSH level. There was no difference between the groups in clinical pregnancy rate (GH = 29%, C = 32%, P = 0.99), number of mature oocytes retrieved (GH = 2.5, C = 5.0, P = 0.13), cycle cancellation rate (GH = 21%, C = 14%, P = 0.88), duration of COH (GH = 10.1, C = 10.1, P = 0.93), or mean peak estradiol level (GH = 4174 pmol/L, C = 5105 pmol/L, P = 0.44). The administration of growth hormone during the

    This study was designed 1) to assess corpus luteum (CL) steroidogenesis in response to exogenous human chorionic gonadotropin (hCG) at different times during the luteal phase, 2) to examine the effect of hCG on steroidogenic acute regulatory protein (StAR) expression within the CL, 3) to correlate StAR expression and luteal steroidogenic responses to hCG, and 4) to determine whether endogenous LH regulates ovarian steroidogenesis in the early luteal phase. Blood was collected before and after hCG treatment for steroid and hCGbeta determinations. CL were obtained at the time of surgery to assess StAR gene and protein expression. During the early luteal phase various women received the GnRH antagonist for 24-48 h; some of them also received hCG 24 h after the GnRH antagonist. A slight steroidogenic response to hCG was observed in early luteal phase; 17alpha-hydroxyprogesterone, but not progesterone (P4), levels were significantly increased 8 h post-hCG, indicating a differential response by the granulosa and theca-lutein cells. The 1.6- and 4.4-kb StAR transcripts and the 37-kDa preprotein and 30-kDa mature StAR protein did not change post-hCG administration in early luteal phase CL. In contrast, the StAR 4.4- and 1.6-kb transcripts diminished significantly (P < 0.05) after the antagonist treatment. Immunohistochemical staining for StAR protein was weak, particularly in granulosa-lutein cells. Treatment with hCG restored StAR mRNA and protein and plasma P4 levels within 24 h in antagonist-treated women. hCG stimulated the highest plasma concentrations of P4 and estradiol in the midluteal phase, indicating its greatest steroidogenic capacity. Midluteal tissue StAR gene and protein expression increased by 1.6- and 1.4-fold after 24 h of hCG treatment, respectively. Administration of hCG resulted in the greatest increment in plasma P4 (4-fold) and 17alpha-hydroxyprogesterone (3-fold) levels over baseline in the late luteal phase. This was associated with an increase in

  18. Luteal-phase ovarian stimulation increases the number of mature oocytes in older women with severe diminished ovarian reserve.

    Rashtian, Justin; Zhang, John


    In older women with severe diminished ovarian response (DOR), in vitro fertilization (IVF) treatment is much less successful due to the low number of mature oocytes collected. The objective of this study was to assess whether follicular-phase stimulation (FPS) and luteal-phase stimulation (LPS) in the same menstrual cycle (double ovarian stimulation) in older women with severe DOR will produce a higher number of oocytes compared to FPS alone. Women with DOR (n = 69; mean age = 42.4) who underwent double ovarian stimulation for IVF were included. Women underwent ovarian stimulation in FPS using clomiphene citrate, letrozole, and gonadotropins followed by oocyte retrieval. The next day following oocyte retrieval, women underwent a second ovarian stimulation (LPS) using the same medications followed by a second oocyte retrieval. T-test was performed in order to compare the clinical characteristics and outcome in the same participant between FPS and LPS. Although antral follicle count at the start of FPS tended to be higher than at the start of the LPS cycle, there was no statistically significant difference between the duration of ovarian stimulation, peak estradiol levels, number of small (FPS alone. The addition of LPS to the conventional FPS increases the number of mature oocytes retrieved in the same IVF cycle, thus potentially increasing the chances of pregnancy in older women with severe DOR. AFC: antral follicle count; BMI: body mass index; DOR: diminished ovarian reserve; E2: estradiol; FPS: follicular-phase stimulation; FSH: follicle stimulating hormone; GnRH: gonadotropin-releasing hormone; HCG: human chorionic gonadotropin; IRB: institutional review board; IVF: in vitro fertilization; LH: luteinizing hormone; LPS: luteal-phase stimulation; MII: metaphase II.

    of a highly nonlinear system to quasi-periodic solar forcing plus noise. This hypothesis was challenged as inconsistent with the observed variability in the phase relation between proxies of solar activity and Greenland climate. Here we reject the claim of inconsistency by showing that this phase variability...... is a robust, generic feature of the nonlinear dynamics of DO events, as described by a model. This variability is expected from the fact that the events are threshold crossing events, resulting from a cooperative process between the periodic forcing and the noise. This process produces a fluctuating phase...

  20. Association of a trait-like bias towards the perception of negative subjective life events with risk of developing premenstrual symptoms.

    Premenstrual symptoms affect the majority of healthy women. Premenstrual symptomatology has earlier been linked to stress and a state-like alteration in the perception of life events in the late-luteal phase of the menstrual cycle. We hypothesised that there is also a trait-like negative bias in the perception of life events evident throughout the whole cycle which is associated with the likelihood to manifest more marked symptoms in the late-luteal phase of the cycle. 88 healthy women completed the PRISM calendar for three consecutive cycles and the Objective and Subjective Event Checklist during the follicular phase of the first cycle. Association between PRISM score change from the follicular through the late-luteal phase and life event variables was investigated by Generalized Linear Model Analysis (GENMOD). The PRISM score change showed a significant negative association with the ratio of positive subjective life events and a significant positive association with the ratio of negative subjective life events. There were no significant results in case of the objective life events. Our results indicate that women manifesting a more marked increase of symptoms from the late follicular through the late-luteal phase of the menstrual cycle are more likely to notice negative subjective life events and less likely to notice positive subjective life events. This suggest a trait-like negative bias in the perception of life events present throughout the whole reproductive cycle which may play an important role in the emergence of premenstrual symptoms.

  1. Effects of intraluteal implants of prostaglandin E1 or E2 on angiogenic growth factors in luteal tissue of Angus and Brahman cows.

    Weems, Yoshie S; Ma, Yan; Ford, Stephen P; Nett, Terry M; Vann, Rhonda C; Lewis, Andrew W; Neuendorff, Don A; Welsh, Thomas H; Randel, Ronald D; Weems, Charles W


    Previously, it was reported that intraluteal implants containing prostaglandin E1 or E2 (PGE1 and PGE2) in Angus or Brahman cows prevented luteolysis by preventing loss of mRNA expression for luteal LH receptors and luteal unoccupied and occupied LH receptors. In addition, intraluteal implants containing PGE1 or PGE2 upregulated mRNA expression for FP prostanoid receptors and downregulated mRNA expression for EP2 and EP4 prostanoid receptors. Luteal weight during the estrous cycle of Brahman cows was reported to be lesser than that of Angus cows but not during pregnancy. The objective of this experiment was to determine whether intraluteal implants containing PGE1 or PGE2 alter vascular endothelial growth factor (VEGF), fibroblast growth factor-2 (FGF-2), angiopoietin-1 (ANG-1), and angiopoietin-2 (ANG-2) protein in Brahman or Angus cows. On Day 13 of the estrous cycle, Angus cows received no intraluteal implant and corpora lutea were retrieved, or Angus and Brahman cows received intraluteal silastic implants containing vehicle, PGE1, or PGE2 on Day 13 and corpora lutea were retrieved on Day 19. Corpora lutea slices were analyzed for VEGF, FGF-2, ANG-1, and ANG-2 angiogenic proteins via Western blot. Day-13 Angus cow luteal tissue served as preluteolytic controls. Data for VEGF were not affected (P > 0.05) by day, breed, or treatment. PGE1 or PGE2 increased (P Angus cows compared with Day-13 and Day-19 Angus controls but decreased (P Angus controls. There was no effect (P > 0.05) of PGE1 or PGE2 on ANG-1 in Angus luteal tissue when compared with Day-13 or Day-19 controls, but ANG-1 was decreased (P Angus Vehicle controls when compared with Day-13 Angus controls, which was prevented (P Angus cows. There was no effect (P > 0.05) of PGE1 or PGE2 on ANG-2 in Brahman cows. PGE1 or PGE2 may alter cow luteal FGF-2, ANG-1, or ANG-2 but not VEGF to prevent luteolysis; however, species or breed differences may exist. Published by Elsevier Inc.

    Larissa Almenara Silva dos Santos


    Full Text Available OBJETIVO: Avaliar o estado nutricional e a ingestão alimentar de mulheres adultas sadias durante o ciclo menstrual. MÉTODOS: Quarenta e cinco voluntárias foram acompanhadas durante três meses. A avaliação do estado nutricional foi baseada no índice de massa corporal, porcentagem de gordura e água corporal. Foram aplicados seis registros alimentares para análise da ingestão dos grupos de alimentos, usando como base o guia alimentar da pirâmide. Para a observação do sintoma "desejos alimentares", foram utilizados três "mapas de sintomas diários". RESULTADOS: Os valores médios de índice de massa corporal e de porcentagem de gordura corporal apresentaram-se normais em ambas as fases, entretanto foi observado maior percentual de mulheres com água corporal acima do padrão na fase lútea (77%. O consumo de alimentos do grupo complementar foi maior na fase lútea. Todos os outros grupos de alimentos, com exceção do grupo de carnes, apresentaram consumo inferior às recomendações, em ambas as fases. A intensidade do sintoma "desejos alimentares" foi leve durante o ciclo menstrual, não sendo observada diferença significativa entre as fases. O sintoma "desejos alimentares" associou-se positivamente com o aumento da ingestão do grupo complementar na fase lútea. CONCLUSÃO: O ciclo menstrual influencia o comportamento alimentar e leva à retenção hídrica, na fase lútea, em mulheres adultas sadias.OBJECTIVE: This study assessed the nutritional status and food intake of healthy young women during the menstrual cycle.

    The objective of this study was to evaluate the influence of epidermal growth factor (EGF) and insulin like growth factor-I (IGF-1) on the in vitro maturation of cat oocytes recovered from follicular and luteal stage ovaries. Oocytes from follicular (n=580) and luteal (n=209) stages were harvested and divided into four groups, which were cultured in FSH-mediated maturation medium supplemented with: (1) EGF alone (25ng/mL); (2) IGF-1 alone (100ng/mL); (3) EGF+IGF-1 (25ng/mL EGF+100ng/mL IGF-I); or (4) no growth factor (control). The proportion of follicular stage oocytes reaching the metaphase II stage was significantly higher than that of oocytes obtained at the luteal stage in both control and study groups (pIGF-1, and 78.1% in EGF+IGF-1 groups, whereas the respective values for gametes collected from luteal stage ovaries were 12.5%, 17.5%, 12.5%, and 16.9%. Additionally, the differences between the study and control groups were significant in the case of follicular stage oocytes. Finally, supplementing the maturation medium with EGF and/or IGF-1 significantly enhanced the meiotic maturation of oocytes recovered from follicular stage ovaries. The present study also demonstrated that the combination of EGF and IGF-I provides an additional or synergic effect on meiotic maturation of oocytes recovered from the follicular stage.

    Primary dysmenorrhea (PD) is a common gynecological disorder which, while not life-threatening, severely affects the quality of life of women. Most patients with PD suffer ovarian hormone imbalances caused by uterine contraction, which results in dysmenorrhea. PD patients may also suffer from increases in estrogen levels caused by increased levels of prostaglandin synthesis and release during luteal regression and early menstruation. Although PD pathogenesis has been previously reported on, these studies only examined the menstrual period and neglected the importance of the luteal regression stage. Therefore, the present study used urine metabolomics to examine changes in endogenous substances and detect urine biomarkers for PD during luteal regression. Ultra performance liquid chromatography coupled with quadrupole-time-of-flight mass spectrometry was used to create metabolomic profiles for 36 patients with PD and 27 healthy controls. Principal component analysis and partial least squares discriminate analysis were used to investigate the metabolic alterations associated with PD. Ten biomarkers for PD were identified, including ornithine, dihydrocortisol, histidine, citrulline, sphinganine, phytosphingosine, progesterone, 17-hydroxyprogesterone, androstenedione, and 15-keto-prostaglandin F2α. The specificity and sensitivity of these biomarkers was assessed based on the area under the curve of receiver operator characteristic curves, which can be used to distinguish patients with PD from healthy controls. These results provide novel targets for the treatment of PD. PMID:28098892

  7. Outpatient management of severe early OHSS by administration of GnRH antagonist in the luteal phase: an observational cohort study

    Lainas George T


    Full Text Available Abstract Background Management of established severe OHSS requires prolonged hospitalization, occasionally in intensive care units, accompanied by multiple ascites punctures, correction of intravascular fluid volume and electrolyte imbalance. The aim of the present study was to evaluate whether it is feasible to manage women with severe OHSS as outpatients by treating them with GnRH antagonists in the luteal phase. Methods This is a single-centre, prospective, observational, cohort study. Forty patients diagnosed with severe OHSS, five days post oocyte retrieval, were managed as outpatients after administration of GnRH antagonist (0.25 mg daily from days 5 to 8 post oocyte retrieval, combined with cryopreservation of all embryos. The primary outcome measure was the proportion of patients with severe OHSS, in whom outpatient management was not feasible. Results 11.3% (95% CI 8.3%-15.0% of patients (40/353 developed severe early OHSS. None of the 40 patients required hospitalization following luteal antagonist administration and embryo cryopreservation. Ovarian volume, ascites, hematocrit, WBC, serum oestradiol and progesterone decreased significantly (P  Conclusions The current study suggests, for the first time, that successful outpatient management of severe OHSS with antagonist treatment in the luteal phase is feasible and is associated with rapid regression of the syndrome, challenging the dogma of inpatient management. The proposed management is a flexible approach that minimizes unnecessary embryo transfer cancellations in the majority (88.7% of high risk for OHSS patients.

  8. Ultrastructural and biochemical evidence for the presence of mature steroidogenic acute regulatory protein (StAR) in the cytoplasm of human luteal cells.

    Sierralta, Walter D; Kohen, Paulina; Castro, Olga; Muñoz, Alex; Strauss, Jerome F; Devoto, Luigi


    The distribution of the steroidogenic acute regulatory protein (StAR) inside thecal and granulosa-lutein cells of human corpus luteum (CL) was assessed by immunoelectron microscopy. We found greater levels of StAR immunolabeling in steroidogenic cells from early- and mid-than in late luteal phase CL and lower levels in cells from women treated with a GnRH antagonist in the mid-luteal phase. Immunoelectron microscopy revealed significant levels of StAR antigen in the mitochondria and in the cytoplasm of luteal cells. The 30 kDa mature StAR protein was present in both mitochondria and cytosol (post-mitochondrial) fractions from homogenates of CL at different ages, whereas cytochrome c and mitochondrial HSP70 were detected only in the mitochondrial fraction. Therefore, we hypothesized that either appreciable processing of StAR 37 kDa pre-protein occurs outside the mitochondria, or mature StAR protein is selectively released into the cytoplasm after mitochondrial processing. The presence of mature StAR in the cytoplasm is consonant with the notion that StAR acts on the outer mitochondrial membrane to effect sterol import, and that StAR may interact with other cytoplasmic proteins involved in cholesterol metabolism, including hormone sensitive lipase.

  9. Gender-specific cerebral activation during cognitive tasks using functional MRI: comparison of women in mid-luteal phase and men

    Gizewski, Elke R.; Wanke, Isabel; Forsting, Michael; Krause, Eva; Senf, Wolfgang


    Previous studies of gender-specific differences in functional imaging during spatial and language tasks have been inconclusive. Furthermore, among women, such differences may occur during mid-luteal phase compared to the rest of the menstrual cycle. In order to examine further gender differences, functional MRI was performed in 12 male volunteers and 12 female volunteers (in the mid-luteal phase) during mental rotation and verb-generation tests. Two-sample t-tests with uncorrected P values of <0.001 for the specific regions of interest (ROIs) revealed cerebral activation differences in both stimuli. During mental rotation tests, higher levels of activation were noted in the right medial frontal, precentral, and bilateral inferior parietal cortex, while in women this occurred in the right inferior and medial temporal, right superior frontal cortex, and left fusiform gyrus. During verb-generation tests, higher levels of activation in men was found in the left medial temporal and precentral cortex. Our results indicate that differences in cerebral activity during cognitive tasks can be shown between men and women in the mid-luteal phase. Gender differences while performing a mental rotation task were more prominent than during a verb-generation task. (orig.)

  10. Late follicular phase administration of levonorgestrel as an emergency contraceptive changes the secretory pattern of glycodelin in serum and endometrium during the luteal phase of the menstrual cycle.

    Durand, Marta; Seppala, Markku; Cravioto, Ma Del Carmen; Koistinen, Hannu; Koistinen, Riitta; González-Macedo, José; Larrea, Fernando


    This study examined serum glycodelin concentrations and endometrial expression during the luteal phase following oral administration of levonorgestrel (LNG) at different stages of the ovarian cycle. Thirty women were recruited and allocated into three groups. All groups were studied during two consecutive cycles, a control cycle and the treatment cycle. In the treatment cycle, each woman received two doses of 0.75 mg LNG taken 12 h apart on days 3-4 before the luteinizing hormone (LH) surge (Group 1), at the time of LH rise (Group 2) and 48 h after the rise in LH was detected (Group 3). Serum progesterone (P) and glycodelin were measured daily during the luteal phase, and an endometrial biopsy was taken at day LH +9 for immunohistochemical glycodelin-A staining. In Group 1, serum P levels were significantly lower, serum glycodelin levels rose earlier and endometrial glycodelin-A expression was weaker than in Groups 2 and 3, in which no differences were found between control and treatment cycles. Levonorgestrel taken for emergency contraception (EC) prior to the LH surge alters the luteal phase secretory pattern of glycodelin in serum and endometrium. Based on the potent gamete adhesion inhibitory activity of glycodelin-A, the results may account for the action of LNG in EC in those women who take LNG before the LH surge.

  11. Effects and safety of GnRH-a as a luteal support in women undertaking assisted reproductive technology procedures: follow-up results for pregnancy, delivery, and neonates.

    Zhou, Weiqin; Zhuang, Yanyan; Pan, Yanping; Xia, Fei


    To investigate the effects and safety of gonadotropin releasing hormone analogue (GnRH-a) as an addition to progesterone luteal support in women who underwent in vitro fertilization/intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET) and achieved a clinical pregnancy. A retrospective analysis was conducted on 214 patients who underwent IVF/ICSI-ET procedures with standard long mid-luteal protocol, of which 123 received GnRH-a-free protocol and 91 received GnRH-a-added protocol. The patients' pregnancy and delivery course, and their neonates' status at birth and growth/development after birth were statistically compared. There was no significant difference between both study groups regarding embryo risks and maternal complications during early pregnancy. as well as fetal risks during the middle and late stages and neonate risks during birth, except that the twin pregnancies of the GnRH-a-added group had a considerably greater male/female ratio, and a significantly higher rate of premature delivery and low birth weight than those of the GnRH-a-free group. In addition, there was no significant difference in neonate risks within 2 years after birth between both cohorts. With precautions taken to control the number of implanted embryos and reduce the incidence of twinning pregnancy, the addition of GnRH-a to luteal support is relatively safe and effective.

  12. Phase relations in the SiC-Al2O3-Pr2O3 system

    Pan, W.; Wu, L.; Jiang, Y.; Huang, Z.


    Phase relations in the Si-Al-Pr-O-C system, including the SiC-Al 2 O 3 -Pr 2 O 3 , the Al 2 O 3 -Pr 2 O 3 -SiO 2 and the SiC-Al 2 O 3 -Pr 2 O 3 -SiO 2 subsystems, were determined by means of XRD phase analysis of solid-state-reacted samples fabricated by using SiC, Al 2 O 3 , Pr 2 O 3 and SiO 2 powders as the starting materials. Subsolidus phase diagrams of the systems were presented. Two Pr-aluminates, namely PrAlO 3 (PrAP) and PrAl 11 O 18 (β(Pr) β-Al 2 O 3 type) were formed in the SiC-Al 2 O 3 -Pr 2 O 3 system. SiC was compatible with both of them. Pr-silicates of Pr 2 SiO 5 , Pr 2 Si 2 O 7 and Pr 9.33 Si 6 O 26 (H(Pr) apatite type) were formed owing to presence of SiO 2 impurity in the SiC powder. The presence of the SiO 2 extended the ternary system of SiC-Al 2 O 3 -Pr 2 O 3 into a quaternary system of SiC-Al 2 O 3 -SiO 2 -Pr 2 O 3 (Si-Al-Pr-O-C). SiC was compatible with Al 2 O 3 , Pr 2 O 3 and the Pr-silicates. The effect of SiO 2 on the phase relations and liquid phase sintering of SiC ceramics was discussed.

  13. Reproductive steroids and ADHD symptoms across the menstrual cycle.

    Roberts, Bethan; Eisenlohr-Moul, Tory; Martel, Michelle M


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

  14. Luteal cell steroidogenesis in relation to delayed embryonic development in the Indian short-nosed fruit bat, Cynopterus sphinx.

    Meenakumari, Karukayil J; Banerjee, Arnab; Krishna, Amitabh


    The primary aim of this study was to determine the possible cause of slow or delayed embryonic development in Cynopterus sphinx by investigating morphological and steroidogenic changes in the corpus luteum (CL) and circulating hormone concentrations during two pregnancies of a year. This species showed delayed post-implantational embryonic development during gastrulation of the first pregnancy. Morphological features of the CL showed normal luteinization during both pregnancies. The CL did not change significantly in luteal cell size during the delay period of the first pregnancy as compared with the second pregnancy. The circulating progesterone and 17beta-estradiol concentrations were significantly lower during the period of delayed embryonic development as compared with the same stage of embryonic development during the second pregnancy. We also showed a marked decline in the activity of 3beta-hydroxysteroid dehydrogenase, P450 side chain cleavage enzyme, and steroidogenic acute regulatory peptide in the CL during the delay period. This may cause low circulating progesterone and estradiol synthesis and consequently delay embryonic development. What causes the decrease in steroidogenic factors in the CL during the period of delayed development in C. sphinx is under investigation.

    Bakas, Panagiotis; Simopoulou, Maria; Giner, Maria; Drakakis, Petros; Panagopoulos, Perikles; Vlahos, Nikolaos


    The objective of this study is to assess if the difference of repeated measurements of estradiol and progesterone during luteal phase predict the outcome of intrauterine insemination. Prospective study. Reproductive clinic. 126 patients with infertility. Patients underwent controlled ovarian stimulation with recombinant FSH (50-150 IU/d). The day of IUI patients were given p.o natural micronized progesterone in a dose of 100 mg/tds. The area under the receiver characteristic operating curve (ROC curve) in predicting clinical pregnancy for % change of estradiol level on days 6 and 10 was 0.892 with 95% CI: 0.82-0.94. A cutoff value of change > -29.5% had a sensitivity of 85.7 with a specificity of 90.2. The corresponding ROC curve for % change of progesterone level was 0.839 with 95% CI: 0.76-0.90. A cutoff value of change > -33% had a sensitivity of 85 with a specificity of 75. The % change of estradiol and progesterone between days 6 and 10 has a predictive ability of pregnancy after IUI with COS of 89.2% and 83.4%, respectively. The addition of % of progesterone to % change of estradiol does not improve the predictive ability of % estradiol and should not be used.

  16. Differential effects of exogenous progesterone administration at different stages of the luteal phase on endogenous oestradiol concentration in cows.

    Starbuck, G R; Mann, G E


    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.

    Humaidan, Peter; Polyzos, N P; Alsbjerg, B


    , there was a lack of blinding in the RCTs. WIDER IMPLICATIONS OF THE FINDINGS: Although a non-significant result, one bolus of 1.500 IU hCG after GnRHa trigger tended to reduce the OHSS rate in patients with 15-25 follicles ≥11 mm as well as secure the ongoing pregnancy rate. In contrast, in patients at low risk......STUDY QUESTION: Does a GnRH agonist (GnRHa) trigger followed by a bolus of 1.500 IU hCG in a group of patients at risk of ovarian hyperstimulation syndrome (OHSS) reduce the OHSS incidence compared with hCG trigger? SUMMARY ANSWER: A GnRHa trigger followed by early luteal hCG support with one bolus...... of 1.500 IU hCG appears to reduce OHSS in patients at risk of OHSS; however, in a low-risk group a second bolus of 1.500 IU hCG induced two cases of late onset OHSS. WHAT IS KNOWN ALREADY: A GnRHa trigger is an alternative to hCG in GnRH antagonist co-treated cycles. STUDY DESIGN, SIZE, DURATION: Two...

  18. The influence of fluorine on phase relations and REE enrichment in alkaline magmas

    Beard, C. D.; van Hinsberg, V.; Stix, J.; Wilke, M.


    Fluorine is a minor element in most magmas, but higher concentrations to wt% levels have been reported in alkaline systems, including those which host economic deposits of REE + HFSE1. Despite low abundance in most natural melts, fluorine has received great attention from the experimental community because it has a strong influence on melt structure, lowering melting points and drastically reducing viscosity. The effect of fluorine on element speciation has important implications for phase relations and the partitioning of trace elements between minerals and melts, thus metal enrichment processes in alkaline magmas. We have experimentally investigated the impact of fluorine on phase relations and partitioning of rare metals, the REE in particular, in evolved alkaline melts. Synthetic glasses of tephriphonolite to phonolite composition were doped with a wide range of elements at trace levels, and fluorine contents were varied from fluorine-free to 2.5 wt%. Experiments were performed water-saturated in an internally heated pressure vessel at 200 MPa with log fO2 at ca. QFM+1, which represents the intrinsic redox conditions of the setup. Charges were heated to super-liquidus conditions for 16 hours, cooled slowly (1˚C/min) to run temperature and subsequently equilibrated for at least 40 hours. Run products were analysed by EPMA and LA-ICP-MS. The experiments produce an equilibrium assemblage of sodic pyroxene, biotite, Fe-oxide, melt, fluid, ±K-feldspar, ±titanite, ±fluorite. Addition of fluorine markedly increases the mode of biotite, which initially buffers melt F content at low levels (< 0.2 wt%). Only in experiments with more than 0.6 wt% F do we observe a significant increase in the melt F-content. Here, fluorine decreases pyroxene/melt partitioning coefficients equally for all REE where pyroxene composition and P-T conditions are equivalent (ca. 1/2 with 0.6% F). We suggest that the formation of REE-F complexes in the melt2 lowers the availability of metals

  2. Impact of Three-Phase Relative Permeability and Hysteresis Models on Forecasts of Storage Associated With CO2-EOR

    Jia, Wei; McPherson, Brian; Pan, Feng; Dai, Zhenxue; Moodie, Nathan; Xiao, Ting


    Geological CO2 sequestration in conjunction with enhanced oil recovery (CO2-EOR) includes complex multiphase flow processes compared to CO2 storage in deep saline aquifers. Two of the most important factors affecting multiphase flow in CO2-EOR are three-phase relative permeability and associated hysteresis, both of which are difficult to measure and are usually represented by numerical interpolation models. The purpose of this study is to improve understanding of (1) the relative impacts of different three-phase relative permeability models and hysteresis models on CO2 trapping mechanisms, and (2) uncertainty associated with these two factors. Four different three-phase relative permeability models and three hysteresis models were applied to simulations of an active CO2-EOR site, the SACROC unit located in western Texas. To eliminate possible bias of deterministic parameters, we utilized a sequential Gaussian simulation technique to generate 50 realizations to describe heterogeneity of porosity and permeability, based on data obtained from well logs and seismic survey. Simulation results of forecasted CO2 storage suggested that (1) the choice of three-phase relative permeability model and hysteresis model led to noticeable impacts on forecasted CO2 sequestration capacity; (2) impacts of three-phase relative permeability models and hysteresis models on CO2 trapping are small during the CO2-EOR injection period, and increase during the post-EOR CO2 injection period; (3) the specific choice of hysteresis model is more important relative to the choice of three-phase relative permeability model; and (4) using the recommended three-phase WAG (Water-Alternating-Gas) hysteresis model may increase the impact of three-phase relative permeability models and uncertainty due to heterogeneity.

  3. Subsolidus phase relations of Bi2O3-Nd2O3-CuO

    Sun Yezhou


    The subsolidus phase relations of the Bi 2 O 3 -Nd 2 O 3 -CuO ternary system and its binary systems along with crystallographic parameters of the compounds were investigated by X-ray powder diffraction and differential thermal analysis. The room temperature section of the phase diagram of the Bi 2 O 3 -Nd 2 O 3 -CuO system can be divided into two diphase regions and six triphase regions. No ternary compound was found. There exist two solid solutions (α, β) and a compound Bi 0.55 Nd 0.45 O 1.5 in the (Bi 2 O 2 ) 1-x (Nd 2 O 3 ) x system. Both solid solution α (0.05≤x≤0.30) and β (0.53≤x≤0.73) belong to the rhombohedral system (R3m). The lattice parameters represented by a hexagonal cell are a=3.9832(4), c=27.536(5) A for Bi 0.8 Nd 0.2 O 1.5 (α phase) and a=3.8826(3), c=9.727(1) A for Bi 0.4 Nd 0.8 O 1.5 (β phase). The Bi 0.55 Nd 0.45 O 1.5 compound crystallizes in a face-centered cubic (f.c.c.) lattice with a=5.5480(2) A. (orig.)

  4. Evaluation of microstructure and phase relations in a powder processed Ti-44Al-12Nb alloy

    Kumar, S.G.; Reddy, R.G.; Wu, J.; Holthus, J.


    Titanium aluminides based on the ordered face-centered tetragonal γTiAl phase possess attractive properties, such as low density, high melting point, good elevated temperature strength, modulus retention, and oxidation resistance, making these alloys potential high-temperature structural materials. These alloys can be processed by both ingot metallurgy and powder metallurgy routes. In the present study, three variations of the powder metallurgy route were studied to process a Ti-44Al-12Nb (at.%) alloy: (a) cold pressing followed by reaction sintering (CP process); (b) cold pressing, vacuum hot pressing, and then sintering (HP process); and (c) arc melting, hydride-dehydride process to make the alloy powder, cold isostatic pressing, and then sintering (AM process). Microstructural and phase relations were studied by x-ray diffraction (XRD) analysis, optical microscopy, scanning electron microscopy with an energy-dispersive spectrometer (SEM-EDS), and electron probe microanalysis (EPMA). The phases identified were Ti 3 Al and TiAl; an additional Nb 2 Al phase was observed in the HP sample. The microstructures of CP and HP processed samples are porous and chemically inhomogeneous whereas the AM processed sample revealed fine equiaxed microstructure. This refinement of the microstructure is attributed to the fine, homogeneous powder produced by the hydride-dehydride process and the high compaction pressures

  5. Subsolidus Phase Relations of the CoOx-CuO-SrO System  

    Grivel, Jean-Claude


    The subsolidus phase relations of the CoOx-CuO-SrO system were investigated in air. The samples were equilibrated at 900 °C. The pseudo-ternary section contains three stoichiometric binary oxide phases (Sr2CuO3, SrCuO2 and Sr14Cu24O41−δ) and a binary oxide solid solution: Sr6+xCo5O15+δ (0 ≤ x ≤ 0.......36). Two binary phases extend into the ternary system forming solid solutions, i.e., Sr14Cu24−xCoxO41−δ (0 ≤ x ≤ 5) and Sr6+xCo5−yCuyO15+δ (0 ≤ x ≤ 0.36, 0 ≤ y ≤ 1.0). The Sr6+xCo5O15+δ solid solution was found to undergo a phase separation into a mixture of Sr6Co5O15−δ and Sr14Co11O33 upon annealing...

  6. Prolactin modulates luteal activity in the short-nosed fruit bat, Cynopterus sphinx during delayed embryonic development.

    Anuradha; Krishna, Amitabh


    The aim of this study was to evaluate the role of prolactin as a modulator of luteal steroidogenesis during the period of delayed embryonic development in Cynopterus sphinx. A marked decline in circulating prolactin levels was noted during the months of November through December coinciding with the period of decreased serum progesterone and delayed embryonic development. The seasonal changes in serum prolactin levels correlated positively with circulating progesterone (P) level, but inversely with circulating melatonin level during first pregnancy showing delayed development in Cynopterus sphinx. The results also showed decreased expression of prolactin receptor-short form (PRL-RS) both in the corpus luteum and in the utero-embryonic unit during the period of delayed embryonic development. Bats treated in vivo with prolactin during the period of delayed development showed significant increase in serum progesterone and estradiol levels together with significant increase in the expression of PRL-RS, luteinizing hormone receptor (LH-R), steroidogenic acute receptor protein (STAR) and 3β-hydroxysteroid dehydrogenase (3β-HSD) in the ovary. Prolactin stimulated ovarian angiogenesis (vascular endothelial growth factor) and cell survival (B-cell lymphoma 2) in vivo. Significant increases in ovarian progesterone production and the expression of prolactin-receptor, LH-R, STAR and 3β-HSD proteins were noted following the exposure of LH or prolactin in vitro during the delayed period. In conclusion, short-day associated increased melatonin level may be responsible for decreased prolactin release during November-December. The decline in prolactin level might play a role in suppressing P and estradiol-17β (E2) estradiol levels thereby causing delayed embryonic development in C. sphinx. Copyright © 2017 Elsevier Inc.

  7. Analysis of genes that influence sheep follicular development by different nutrition levels during the luteal phase using expression profiling.

    Luo, F; Jia, R; Ying, S; Wang, Z; Wang, F


    Nutrition is an important factor that regulates reproductive performance of sheep and affects follicle development. However, the correlation between nutrition and follicle development is poorly understood at the molecular level. To study its possible molecular mechanisms, we performed expression profiling of granulosa cells isolated from sheep that were fed different levels of nutrition levels during the luteal phase. To do this, ewes received a maintenance diet (M), and their estrus was synchronized by intravaginal progestogen sponges for 12 days. Ewes were randomly divided into the short-term dietary-restricted group (R; 0.5 × M) and the nutrient-supplemented group (S; 1.5 × M). RNA samples were extracted from granulosa cells. Transcriptome libraries from each group were constructed by Illumina sequencing. Among 18 468 detected genes, 170 genes were significantly differentially expressed, of which 140 genes were upregulated and 30 genes were downregulated in group S relative to group R. These genes could be candidates regulating follicular development in sheep. Gene Ontology, KEGG and clustering analyses were performed. Genes related to oocyte meiosis, such as ADCY7, were upregulated. We identified two important groups of related genes that were upregulated with improved nutrition: one group comprising the genes PTGS2, UCP2 and steroidogenic acute regulatory protein and the other group comprising interleukin-1A and interleukin-1B. The genes within each group showed similar expression patterns. Additionally, all five genes are involved in the reproduction process. Quantitative real-time PCR was performed to validate the results of expression profiling. These data in our study are an abundant genomic resource to expand the understanding of the molecular and cellular events underlying follicle development. © 2016 Stichting International Foundation for Animal Genetics.

  8. Assessment of the proliferative, apoptotic and cellular renovation indices of the human mammary epithelium during the follicular and luteal phases of the menstrual cycle

    Navarrete, Maria Alicia H; Maier, Carolina M; Falzoni, Roberto; Quadros, Luiz Gerk de Azevedo; Lima, Geraldo R; Baracat, Edmund C; Nazário, Afonso CP


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

  9. Molecular Signatures of Immune Activation and Epithelial Barrier Remodeling Are Enhanced during the Luteal Phase of the Menstrual Cycle: Implications for HIV Susceptibility.

    Birse, Kenzie; Arnold, Kelly B; Novak, Richard M; McCorrister, Stuart; Shaw, Souradet; Westmacott, Garrett R; Ball, Terry B; Lauffenburger, Douglas A; Burgener, Adam


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

  10. Duration of luteal support (DOLS with progesterone pessaries to improve the success rates in assisted conception: study protocol for a randomized controlled trial

    Gazvani Rafet


    Full Text Available Abstract Background Luteal support with progesterone is necessary for successful implantation of the embryo following egg collection and embryo transfer in an in-vitro fertilization (IVF cycle. Progesterone has been used for as little as 2 weeks and for as long as 12 weeks of gestation. The optimal length of treatment is unresolved at present and it remains unclear how long to treat women receiving luteal supplementation. Design The trial is a prospective, randomized, double-blind, placebo-controlled trial to investigate the effect of the duration of luteal support with progesterone in IVF cycles. Following 2 weeks standard treatment and a positive biochemical pregnancy test, this randomized control trial will allocate women to a supplementary 8 weeks treatment with vaginal progesterone or 8 weeks placebo. Further studies would be required to investigate whether additional supplementation with progesterone is beneficial in early pregnancy. Discussion Currently at the Hewitt Centre, approximately 32.5% of women have a positive biochemical pregnancy test 2 weeks after embryo transfer. It is this population that is eligible for trial entry and randomization. Once the patient has confirmed a positive urinary pregnancy test they will be invited to join the trial. Once the consent form has been completed by the patient a trial prescription sheet will be sent to pharmacy with a stated collection time. The patient can then be randomized and the drugs dispensed according to pharmacy protocol. A blood sample will then be drawn for measurement of baseline hormone levels (progesterone, estradiol, free beta-human chorionic gonadotrophin, pregnancy-associated plasma protein-A, Activin A, Inhibin A and Inhibin B. The primary outcome measure is the proportion of all randomized women that continue successfully to a viable pregnancy (at least one fetus with fetal heart rate >100 beats/minute on transabdominal/transvaginal ultrasound at 10 weeks post embryo

  11. Effects of single dose GnRH agonist as luteal support on pregnancy outcome in frozen-thawed embryo transfer cycles: an RCT

    Robab Davar


    Full Text Available Background: There is no doubt that luteal phase support is essential to enhance the reproductive outcome in IVF cycles. In addition to progesterone and human chorionic gonadotropin, several studies have described GnRH agonists as luteal phase support to improve implantation rate, pregnancy rate and live birth rate, whereas other studies showed dissimilar conclusions. All of these studies have been done in fresh IVF cycles. Objective: To determine whether an additional GnRH agonist administered at the time of implantation for luteal phase support in frozen-thawed embryo transfer (FET improves the embryo developmental potential. Materials and Methods: This is a prospective controlled trial study in 200 FET cycles, patients were randomized on the day of embryo transfer into group 1 (n=100 to whom a single dose of GnRH agonist (0.1 mg triptorelin was administered three days after transfer and group 2 (n=100, who did not receive agonist. Both groups received daily vaginal progesterone suppositories plus estradiol valerate 6 mg daily. Primary outcome measure was clinical pregnancy rate. Secondary outcome measures were implantation rate, chemical, ongoing pregnancy rate and abortion rate. Results: A total of 200 FET cycles were analyzed. Demographic data and embryo quality were comparable between two groups. No statistically significant difference in clinical and ongoing pregnancy rates was observed between the two groups (26% versus 21%, p=0.40 and 21% versus 17%, p=0.37, respectively. Conclusion: Administration of a subcutaneous GnRH agonist at the time of implantation does not increase clinical or ongoing pregnancy.

  13. Phase relations and gibbs energies in the system Mn-Rh-O

    Jacob, K. T.; Sriram, M. V.


    Phase relations in the system Mn-Rh-O are established at 1273 K by equilibrating different compositions either in evacuated quartz ampules or in pure oxygen at a pressure of 1.01 × 105 Pa. The quenched samples are examined by optical microscopy, X-ray diffraction, and energy-dispersive X-ray analysis (EDAX). The alloys and intermetallics in the binary Mn-Rh system are found to be in equilibrium with MnO. There is only one ternary compound, MnRh2O4, with normal spinel structure in the system. The compound Mn3O4 has a tetragonal structure at 1273 K. A solid solution is formed between MnRh2O4 and Mn3O4. The solid solution has the cubic structure over a large range of composition and coexists with metallic rhodium. The partial pressure of oxygen corresponding to this two-phase equilibrium is measured as a function of the composition of the spinel solid solution and temperature. A new solid-state cell, with three separate electrode compartments, is designed to measure accurately the chemical potential of oxygen in the two-phase mixture, Rh + Mn3-2xRh2xO4, which has 1 degree of freedom at constant temperature. From the electromotive force (emf), thermodynamic mixing properties of the Mn3O4-MnRh2O4 solid solution and Gibbs energy of formation of MnRh2O4 are deduced. The activities exhibit negative deviations from Raoult’s law for most of the composition range, except near Mn3O4, where a two-phase region exists. In the cubic phase, the entropy of mixing of the two Rh3+ and Mn3+ ions on the octahedral site of the spinel is ideal, and the enthalpy of mixing is positive and symmetric with respect to composition. For the formation of the spinel (sp) from component oxides with rock salt (rs) and orthorhombic (orth) structures according to the reaction, MnO (rs) + Rh2O3 (orth) → MnRh2O4 (sp), ΔG° = -49,680 + 1.56T (±500) J mol-1 The oxygen potentials corresponding to MnO + Mn3O4 and Rh + Rh2O3 equilibria are also obtained from potentiometric measurements on galvanic

  14. Calculated Phase Relations in the System KFMASH Between 6 and 16 GPa

    Massonne, H.; Brandelik, A.


    To better understand the modal compositions of deeply buried metagranitoids and metapelites, phase relations in the model system K2O-FeO-MgO-Al2O3-SiO2-H2O (KFMASH) with SiO2 in excess were calculated applying thermodynamic principles. We used the software package PTGIBBS, published data, and thermodynamic data (e.g. for phase egg (AlSiO3OH), K-hollandite (KAlSi3O8)) newly derived on the basis of former high-pressure (HP) experiments. Non-ideal mixing was considered for the solid solution series of garnet (components: pyrope, majorite, almandine) and potassic white mica (components: muscovite, MgAl-celadonite, FeAl-celadonite). For phases such as HP-clinoenstatite ((Mg,Fe)SiO3), Si-spinel ((Fe,Mg)2SiO4), and beta phase ((Mg,Fe)2SiO4) only binary solid solutions, assuming ideal mixing, were taken into account. On the basis of the above data, we constructed petrogenetic grids mainly for the P-T range 6 to 16 GPa and 600 to 1600 ° C. Typical features of these grids are, for instance, the disappearance of K-cymrite (KAlSi3O8 H2O) with rising pressure close to 10 GPa and the occurrence of phase egg above 12 GPa. In KMASH potassic white mica reacts with OH-topaz at about 11 GPa (1000-1200 ° C) to form pyrope + K-hollandite. The content of majorite component in pyrope is less than 1 mol% which is systematically so for all garnets coexisting with an Al-silicate at least up to 16 GPa. Potassic white mica, which is virtually pure MgAl-celadonite, finally breaks down at pressures close to 12 GPa. Decomposition assemblages are K-hollandite + HP-clinoenstatite + H2O (T free) garnet + Al-silicate. The latter phase is either OH-topaz (Al2SiO4(OH)2) or phase egg or kyanite also depending on the availability of H2O. Metagranitoids should be composed of shishovite + K-hollandite + majorite-bearing garnet + (enstatite-rich) clinopyroxene. Si-spinel is an important additional phase in this assemblage. This phase shows increasing amounts by approaching to 16 GPa.

  16. Phase relations in the hydrous CMAS pyrolite in presence of KCl at 2 GPa

    Safonov, O.


    In the upper mantle, chlorides are constituents of concentrated aqueous solutions (brines), as well as chloride-carbonate and carbonatite melts. Mineral assemblages coming from diverse depth levels show that mobile (K, Na)Cl-bearing fluids are able to provoke intensive metasomatism of the peridotitic mantle accompanied by melting. Scarce experimental studies on influence of brines on mineral equilibria in the peridotitic mantle (Stalder et al., 2008; Chu et al., 2011) indicate that influence of chlorides on water activity in a fluid equilibrated with forsterite enstatite at pressures above 2 GPa is very similar to their effect at lower "crustal" pressures (e.g. Aranovich, Newton, 1997): decrease of the H2O activity with an increase of the salt content results in an increase of the melting temperature of silicates. Nevertheless, these experiments were performed in the Al-free systems. Presence of Al would provoke an active interaction of alkali chlorides, namely KCl, with silicates with formation of new K-Al-bearing phases, such as phlogopite (in presence of H2O), which would influence on the melting of complex assemblages. In order to investigate an effect of KCl on phase relations in the Al2O3, CaO, Na2O-rich hydrous peridotite and on stability of garnet, pyroxenes, and amphiboles, in particular, experiments on interaction of the model CMAS pyrolite Fo57En17Prp14Di12 (+0.3 wt. % of Na2O) with the H2O-KCl fluid were performed at 2 GPa in the temperature interval 900-1200. Mixtures of synthetic forsterite, diopside, enstatite and pyrope in the above weight ratio were mixed with 14 wt. % of Mg(OH)2 corresponding to 4.4 wt. % of H2O in the system. 2.4, 3.7, 5 and 10 wt. % of KCl were added to silicate-H2O mixture. Experiments were performed using a piston-cylinder apparatus with ½-inch talc high-pressure cells calibrated via brucite = periclase + H2O and albite = jadeite + quartz equilibria curves. Temperature was controlled with accuracy ?1 with the W95Re5/W80Re20

  17. Roles of prostaglandin F2alpha and hydrogen peroxide in the regulation of Copper/Zinc superoxide dismutase in bovine corpus luteum and luteal endothelial cells

    Vu Hai V


    Full Text Available Abstract Background Prostaglandin F2alpha (PGF induces luteolysis in cow by inducing a rapid reduction in progesterone production (functional luteolysis followed by tissue degeneration (structural luteolysis. However the mechanisms of action of PGF remain unclear. Reactive oxygen species (ROS play important roles in regulating the luteolytic action of PGF. The local concentration of ROS is controlled by superoxide dismutase (SOD, the main enzyme involved in the control of intraluteal ROS. Thus SOD seems to be involved in luteolysis process induced by PGF in cow. Methods To determine the dynamic relationship between PGF and ROS in bovine corpus luteum (CL during luteolysis, we determined the time-dependent change of Copper/Zinc SOD (SOD1 in CL tissues after PGF treatment in vivo. We also investigated whether PGF and hydrogen peroxide (H2O2 modulates SOD1 expression and SOD activity in cultured bovine luteal endothelial cells (LECs in vitro. Results Following administration of a luteolytic dose of PGF analogue (0 h to cows at the mid-luteal stage, the expression of SOD1 mRNA and protein, and total SOD activity in CL tissues increased between 0.5 and 2 h, but fell below the initial (0 h level at 24 h post-treatment. In cultured LECs, the expression of SOD1 mRNA was stimulated by PGF (1–10 microM and H2O2 (10–100 microM at 2 h (P

  18. The loss of luteal progesterone production in women is associated with a galectin switch via α2,6-sialylation of glycoconjugates.

    Nio-Kobayashi, Junko; Boswell, Lyndsey; Amano, Maho; Iwanaga, Toshihiko; Duncan, W Colin


    Luteal progesterone is fundamental for reproduction, but the molecular regulation of the corpus luteum (CL) in women remains unclear. Galectin-1 and galectin-3 bind to the sugar chains on cells to control key biological processes including cell function and fate. The expression and localization of LGALS1 and LGALS3 were analyzed by quantitative PCR and histochemical analysis, with special reference to α2,6-sialylation of glycoconjugates in carefully dated human CL collected across the menstrual cycle and after exposure to human chorionic gonadotrophin (hCG) in vivo. The effects of hCG and prostaglandin E2 on the expression of galectins and an α2,6-sialyltransferase 1 (ST6GAL1) in granulosa lutein cells were analyzed in vitro. Galectin-1 was predominantly localized to healthy granulosa lutein cells and galectin-3 was localized to macrophages and regressing granulosa lutein cells. Acute exposure to luteotrophic hormones (hCG and prostaglandin E2) up-regulated LGALS1 expression (P progesterone synthesis. Luteotrophic hormones differentially regulate galectin-1 and galectin-3/α2,6-sialylation in granulosa lutein cells, suggesting a novel galectin switch regulated by luteotrophic stimuli during luteolysis and luteal rescue.

    Boldt, Ariane; Becker, Frank; Martin, Gunter; Nürnberg, Gerd; Römer, Anke; Kanitz, Wilhelm


    The interval from calving to commencement of luteal activity (CLA) was determined by progesterone measurements from milk samples obtained once a week until the 14th week post-partum in 513 German Holstein cows in first to third parity. Milk samples were analyzed by an "on-farm" device (eProCheck(®), Minitüb, Germany) and simultaneously by RIA. The objective of this study was to examine the effect of milk yield, protein content and body condition of a cow on the CLA post-partum. Milk progesterone concentrations of "on-farm" measurements correlated with measurements done by the RIA-method significantly (r=0.72; PCows with a milk protein content at 1st milk recording of ≤3.5% revealed first luteal activity 1.3±0.3 weeks later than cows that had a content of >3.75% protein (Pcows with assisted calving or dystocia presented significantly later CLA than cows which required no help during the calving process (Pfertility cannot be confirmed regarding to CLA. The negative energy balance after calving, caused by the high milk yields, is more detrimental for the cyclical activity as was shown by the parameters milk protein content and change in BFT.

    Evidence obtained during recent years provided has insight into the regulation of corpus luteum (CL) development, function, and regression by locally produced ghrelin. The present study was carried out to evaluate the expression and localization of ghrelin and its receptor (GHS-R1a) in bubaline CL during different stages of the estrous cycle and investigate the role of ghrelin on progesterone (P4) production along with messenger RNA (mRNA) expression of P4 synthesis intermediates. The mRNA and protein expression of ghrelin and GHS-R1a was significantly greater in mid- and late luteal phases. Both factors were localized in luteal cells, exclusively in the cytoplasm. Immunoreactivity of ghrelin and GHS-R1a was greater during mid- and late luteal phases. Luteal cells were cultured in vitro and treated with ghrelin each at 1, 10, and 100 ng/mL concentrations for 48 h after obtaining 75% to 80% confluence. At a dose of 1 ng/mL, there was no significant difference in P4 secretion between control and treatment group. At 10 and 100 ng/mL, there was a decrease (P production in buffalo.

  3. Non-reproductive Effects of Anovulation: Bone Metabolism in the Luteal Phase of Premenopausal Women Differs between Ovulatory and Anovulatory Cycles.

    Niethammer, B; Körner, C; Schmidmayr, M; Luppa, P B; Seifert-Klauss, V R


    Introduction: Several authors have linked subclinical ovulatory disturbances in normal length menstrual cycles to premenopausal fracture risk and bone changes. This study systematically examined the influence of ovulation and anovulation on the bone metabolism of premenopausal women. Participants and Methods: In 176 cycles in healthy premenopausal women, FSH, 17β-estradiol (E2) and progesterone (P4) as well as bone alkalic phosphatase (BAP), pyridinoline (PYD) and C-terminal crosslinks (CTX) were measured during the follicular and during the luteal phase. The probability and timing of ovulation was self-assessed by a monitoring device. In addition, bone density of the lumbar spine was measured by quantitative computed tomography (QCT) at baseline and at the end of the study. Analysis was restricted to blood samples taken more than three days before the following menstruation. Results: 118 cycles out of the 176 collected cycles were complete with blood samples taken within the correct time interval. Of these, 56.8 % were ovulatory by two criteria (ovulation symbol shown on the monitor display and LP progesterone > 6 ng/ml), 33.1 % were possibly ovulatory by one criterion (ovulation symbol shown on the monitor display or LP progesterone > 6 ng/ml), and 10.2 % were anovulatory by both criteria). Ovulation in the previous cycle and in the same cycle did not significantly influence the mean absolute concentrations of the bone markers. However, bone formation (BAP) was higher in the luteal phase of ovulatory cycles than in anovulatory cycles (n. s.) and the relative changes within one cycle were significantly different for bone resorption (CTX) during ovulatory vs. anovulatory cycles (p cycles following each other directly, both ovulation in the previous cycle and ovulation in the present cycle influenced CTX, but not the differences of other bone markers. Conclusion: Ovulatory cycles reduce bone resorption in their luteal phase and that of the

The mean concentrations of glucose were significantly different during the follicular and luteal phases.

  5. Expression and localization of insulin-like growth factor system in corpus luteum during different stages of estrous cycle in water buffaloes (Bubalus bubalis) and the effect of insulin-like growth factor I on production of vascular endothelial growth factor and progesterone in luteal cells cultured in vitro.

    Uniyal, S; Panda, R P; Chouhan, V S; Yadav, V P; Hyder, I; Dangi, S S; Gupta, M; Khan, F A; Sharma, G T; Bag, S; Sarkar, M


    This study investigated the expression and localization of insulin-like growth factor (IGF) system at different stages of buffalo CL and the role of IGF-I in stimulating vascular endothelial growth factor (VEGF) and progesterone (P4) production in cultured luteal cells. The mRNA expression of IGF system, VEGF, steroidogenic acute regulatory protein, P450scc, and hydroxysteroid dehydrogenase (HSD) was investigated by quantitative real-time polymerase chain reaction (PCR). Protein expression of IGF was demonstrated by Western blot and localization by immunohistochemistry. Progesterone and VEGF production was assayed using RIA and ELISA. A relatively high mRNA expression of IGF-I and IGF-II in early, mid- and late luteal phases with immunoreactivity mostly restricted to cytoplasm of large luteal cells indicates their autocrine role, whereas very weak immunoreactivity in endothelial cells during the mid-luteal phase indicates their paracrine role. Insulin-like growth factor receptors, IGF-IR and IGF-IIR, were restricted to large luteal cells with high mRNA and protein expressions in the mid-luteal phase. The significantly higher expression of insulin-like growth factor binding protein (IGFBP)-1, -3, -5, and -6 in the early or mid-luteal phase suggested their stimulatory role, whereas that of IGFBP-2 and -4 in mid-, late, and regressive luteal stages implied their inhibitory role. The mRNA expressions of key steroidogenic factors and VEGF were significantly higher (P production (P production of VEGF in luteal cells and steroid synthesis through the production of key steroidogenic factors.

  8. Progesterone concentration, pregnancy and calving rate in Simmental dairy cows after oestrus synchronisation and hCG treatment during the early luteal phase.

    Šuluburić, Adam; Milanović, Svetlana; Vranješ-Đurić, Sanja; Jovanović, Ivan B; Barna, Tomislav; Stojić, Milica; Fratrić, Natalija; Szenci, Ottó; Gvozdić, Dragan


    Early embryonic development may be negatively affected by insufficient progesterone (P4) production. Therefore, the aim of our study was to increase P4 by gonadotropin-releasing hormone (GnRH) and/or human chorionic gonadotropin (hCG) treatments after inducing oestrus by prostaglandin (PG) treatment. Lactating Simmental dairy cows (n = 110), between 1 to 5 lactations, with an average milk production of 6,500 1/305 days, at 40-80 days postpartum were used and grouped as follows: (1) PG + GnRH treatment at AI (GnRH group), (2) PG + hCG treatment at day 7 after AI (hCG group), (3) PG + GnRH at AI + hCG treatment at day 7 after AI (GnRH/hCG group), and (4) spontaneous oestrus (C: control group). All animals were double inseminated (at the time of oestrus detection and 12 ± 2 h thereafter). Blood serum and milk samples were collected at the day of observed oestrus (day 0), and 14, 21 and 28 days after AI. Serum P4 was determined using a commercial radioimmunoassay (RIA) test (INEP, Zemun), and milk P4 was determined using enzyme-linked immunoassay (ELISA) test (NIV Novi Sad). Pregnancy status was confirmed by ultrasonography between days 28 and 35 after AI. Differences of serum or milk P4 medians, pregnancy (and calving) rate were determined using Dunn's Multiple Comparison Tests and Z test, respectively. Serum P4 medians were significantly higher at days 14, 21 and 28 after AI in the hCG-treated animals, indicating increased luteal activity, with a similar tendency in whole milk P4 values. Treatment with hCG during the early luteal phase significantly contributed to the maintenance of gestation at days 28-35 after AI, and also increased the calving rate in Simmental dairy cows.

  9. Evaluating therapeutic effect in symptoms of moderate-to-severe premenstrual syndrome with Vitex agnus castus (BNO 1095) in Chinese women.

    Ma, Linlin; Lin, Shouqing; Chen, Rong; Zhang, Ying; Chen, Fengling; Wang, Xiuli


    To assess therapeutic effect of an extract of Vitex agnus castus (VAC, BNO 1095) in premenstrual syndrome (PMS) in Chinese women. It was a prospective, randomised, double-blind, placebo-controlled study carried out in China. Eligible patients were treated with VAC extract or placebo for three cycles. Symptoms were documented with PMS diary (PMSD), a daily rating scale with 17 items. Main efficacy variable was the reduction percentage of 17 symptom score documented in PMSD during the luteal phase of the third treatment cycle. A total of 67 patients were enrolled and randomly assigned to VAC group or placebo group. Of these, 64 patients completed the study (31 vs. 33). All the 17 symptoms showed a significantly greater improvement with VAC than placebo (P 0.05). Vitex agnus castus is more effective than placebo in the treatment of moderate-to-severe PMS in Chinese women, especially in symptoms of negative effect and insomnia.

  11. Phase relations in a forced turbulent boundary layer: implications for modelling of high Reynolds number wall turbulence.

    Duvvuri, Subrahmanyam; McKeon, Beverley


    Phase relations between specific scales in a turbulent boundary layer are studied here by highlighting the associated nonlinear scale interactions in the flow. This is achieved through an experimental technique that allows for targeted forcing of the flow through the use of a dynamic wall perturbation. Two distinct large-scale modes with well-defined spatial and temporal wavenumbers were simultaneously forced in the boundary layer, and the resulting nonlinear response from their direct interactions was isolated from the turbulence signal for the study. This approach advances the traditional studies of large- and small-scale interactions in wall turbulence by focusing on the direct interactions between scales with triadic wavenumber consistency. The results are discussed in the context of modelling high Reynolds number wall turbulence.This article is part of the themed issue 'Toward the development of high-fidelity models of wall turbulence at large Reynolds number'. © 2017 The Author(s).

  12. The expression pattern of microRNAs in granulosa cells of subordinate and dominant follicles during the early luteal phase of the bovine estrous cycle.

    Dessie Salilew-Wondim

    Full Text Available This study aimed to investigate the miRNA expression patterns in granulosa cells of subordinate (SF and dominant follicle (DF during the early luteal phase of the bovine estrous cycle. For this, miRNA enriched total RNA isolated from granulosa cells of SF and DF obtained from heifers slaughtered at day 3 and day 7 of the estrous cycle was used for miRNAs deep sequencing. The results revealed that including 17 candidate novel miRNAs, several known miRNAs (n = 291-318 were detected in SF and DF at days 3 and 7 of the estrous cycle of which 244 miRNAs were common to all follicle groups. The let-7 families, bta-miR-10b, bta-miR-26a, bta-miR-99b and bta-miR-27b were among abundantly expressed miRNAs in both SF and DF at both days of the estrous cycle. Further analysis revealed that the expression patterns of 16 miRNAs including bta-miR-449a, bta-miR-449c and bta-miR-222 were differentially expressed between the granulosa cells of SF and DF at day 3 of the estrous cycle. However, at day 7 of the estrous cycle, 108 miRNAs including bta-miR-409a, bta-miR-383 and bta-miR-184 were differentially expressed between the two groups of granulosa cell revealing the presence of distinct miRNA expression profile changes between the two follicular stages at day 7 than day 3 of the estrous cycle. In addition, unlike the SF, marked temporal miRNA expression dynamics was observed in DF groups between day 3 and 7 of the estrous cycle. Target gene prediction and pathway analysis revealed that major signaling associated with follicular development including Wnt signaling, TGF-beta signaling, oocyte meiosis and GnRH signaling were affected by differentially expressed miRNAs. Thus, this study highlights the miRNA expression patterns of granulosa cells in subordinate and dominant follicles that could be associated with follicular recruitment, selection and dominance during the early luteal phase of the bovine estrous cycle.

There was no significant difference(P>0.05 in luteolytic ability between PGF2? cell culture product and dinoprost. In conclusion, the PGF2?could be produced by monolayer cell culture of bali cattle is endometrial and seminal vesicle epithelialcells more over they have similar ability with dinoprost in luteolytic ability.

  14. Stimulation of the young poor responder: comparison of the luteal estradiol/gonadotropin-releasing hormone antagonist priming protocol versus oral contraceptive microdose leuprolide.

    Shastri, Shefali M; Barbieri, Elizabeth; Kligman, Isaac; Schoyer, Katherine D; Davis, Owen K; Rosenwaks, Zev


    To evaluate in vitro fertilization (IVF) cycle outcomes in young poor responders treated with a luteal estradiol/gonadotropin-releasing hormone antagonist (E(2)/ANT) protocol versus an oral contraceptive pill microdose leuprolide protocol (OCP-MDL). Retrospective cohort. Academic practice. Poor responders: 186 women, aged <35 years undergoing IVF with either E(2)/ANT or OCP-MDL protocols. None. Clinical pregnancies, oocytes retrieved, cancellation rate. Patients in the E(2)/ANT group had a greater gonadotropin requirement (71.9 ± 22.2 vs. 57.6 ± 25.7) and lower E(2) level (1,178.6 ± 668 vs. 1,627 ± 889), yet achieved similar numbers of oocytes retrieved and fertilized, and a greater number of embryos transferred (2.3 ± 0.9 vs. 2.0 ± 1.1) with a better mean grade (2.14 ± .06 vs. 2.7 ± 1.8) compared with the OCP/MDL group. The E2/ANT group exhibited a trend toward improved implantation rates (30.5% vs. 21.1%) and ongoing pregnancy rates per started cycle: 44 out of 117 (37%) versus 17 out of 69 (25%). Poor responders aged <35 years may be treated with the aggressive E(2)/ANT protocol to improve cycle outcomes. Both protocols remain viable options for this group. Adequately powered, randomized clinical comparison appears justified. Copyright © 2011 American Society for Reproductive Medicine. Published by Elsevier Inc. All rights reserved.

  15. High-pressure phase relations and thermodynamic properties of CaAl 4Si 2O 11 CAS phase

    Akaogi, M.; Haraguchi, M.; Yaguchi, M.; Kojitani, H.


    Phase relations in CaAl4Si2O11 were examined at 12-23 GPa and 1000-1800 °C by multianvil experiments. A three-phase mixture of grossular, kyanite and corundum is stable below about 13 GPa at 1000-1800 °C. At higher pressure and at temperature below about 1200 °C, a mixture of grossular, stishovite and corundum is stable, indicating the decomposition of kyanite. Above about 1200 °C, CaAl4Si2O11 CAS phase is stable at pressure higher than about 13 GPa. The triple point is placed at 14.7 GPa and 1280 °C. The equilibrium boundary of formation of CAS phase from the mixture of grossular, kyanite and corundum has a small negative slope, and that from the mixture of grossular, stishovite and corundum has a strongly negative slope, while the decomposition boundary of kyanite has a small positive slope. Enthalpies of the transitions were measured by high-temperature drop-solution calorimetry. The enthalpy of formation of CaAl4Si2O11 CAS phase from the mixture of grossular, kyanite and corundum was 139.5 ± 15.6 kJ/mol, and that from the mixture of grossular, stishovite and corundum was 94.2 ± 15.4 kJ/mol. The transition boundaries calculated using the measured enthalpy data were consistent with those determined by the high-pressure experiments. The boundaries in this study are placed about 3 GPa higher in pressure and about 200 °C lower in temperature than those by Zhai and Ito [Zhai, S., Ito, E., 2008. Phase relations of CaAl4Si2O11 at high-pressure and high-temperature with implications for subducted continental crust into the deep mantle. Phys. Earth Planet. Inter. 167, 161-167]. Combining the thermodynamic data measured in this study with those in the literature, dissociation boundary of CAS phase into a mixture of Ca-perovskite, corundum and stishovite and that of grossular into Ca-perovskite plus corundum were calculated to further constrain the stability field of CAS phase. The result suggests that the stability of CAS phase would be limited at the bottom of

  16. Paternal epigenetic effects of population density on locust phase-related characteristics associated with heat-shock protein expression.

    Chen, Bing; Li, Shaoqin; Ren, Qiang; Tong, Xiwen; Zhang, Xia; Kang, Le


    Many species exhibit transgenerational plasticity by which environmental cues experienced by either parent can be transmitted to their offspring, resulting in phenotypic variants in offspring to match ancestral environments. However, the manner by which paternal experiences affect offspring plasticity through epigenetic inheritance in animals generally remains unclear. In this study, we examined the transgenerational effects of population density on phase-related traits in the migratory locust Locusta migratoria. Using an experimental design that explicitly controls genetic background, we found that the effects of crowd or isolation rearing on phase plasticity could be inherited to the offspring. The isolation of gregarious locusts resulted in reduced weight in offspring eggs and altered morphometric traits in hatchlings, whereas crowding of solitarious locusts exhibited opposite effects. The consequences of density changes were transmitted by both maternal and paternal inheritance, although the expression of paternal effects was not as pronounced as that of maternal effects. Prominent expression of heat-shock proteins (Hsps), such as Hsp90, Hsp70 and Hsp20.6, could be triggered by density changes. Hsps were significantly upregulated upon crowding but downregulated upon isolation. The variation in parental Hsp expression was also transmitted to the offspring, in which the pattern of inheritance was consistent with that of phase characteristics. These results revealed a paternal effect on phase polyphenism and Hsp expression induced by population density, and defined a model system that could be used to study the paternal epigenetic inheritance of environmental changes. © 2015 John Wiley & Sons Ltd.

  18. Fetal programming: prenatal testosterone treatment leads to follicular persistence/luteal defects; partial restoration of ovarian function by cyclic progesterone treatment.

    Manikkam, Mohan; Steckler, Teresa L; Welch, Kathleen B; Inskeep, E Keith; Padmanabhan, Vasantha


    Prenatal testosterone (T) excess during midgestation leads to estrous cycle defects and polycystic ovaries in sheep. We hypothesized that follicular persistence causes polycystic ovaries and that cyclic progesterone (P) treatment would overcome follicular persistence and restore cyclicity. Twice-weekly blood samples for P measurements were taken from control (C; n = 16) and prenatally T-treated (T60; n = 14; 100 mg T, im, twice weekly from d 30-90 of gestation) Suffolk sheep starting before the onset of puberty and continuing through the second breeding season. A subset of C and T60 sheep were treated cyclically with a modified controlled internal drug-releasing device for 13-14 d every 17 d during the first anestrus (CP, 7; TP, 6). Transrectal ovarian ultrasonography was performed for 8 d in the first and 21 d in the second breeding season. Prenatal T excess reduced the number, but increased the duration of progestogenic cycles, reduced the proportion of ewes with normal cycles, increased the proportion of ewes with subluteal cycles, decreased the proportion of ewes with ovulatory cycles, induced the occurrence of persistent follicles, and reduced the number of corpora lutea in those that cycled. Cyclic P treatment in anestrus, which produced one third the P concentration seen during luteal phase of cycle, did not reduce the number of persistent follicles, but increased the number of progestogenic cycles while reducing their duration. These findings suggested that follicular persistence might contribute to the polycystic ovarian morphology. Cyclic P treatment was able to only partially restore follicular dynamics, but this may be related to the low replacement concentrations of P achieved.

  19. Effects of different five-day progesterone-based fixed-time AI protocols on follicular/luteal dynamics and fertility in dairy cows



    This study compares in two experiments the responses of lactating dairy cows to four different progesterone-based protocols for fixed-time artificial insemination (FTAI) in terms of their effects on follicular/luteal dynamics and fertility. The protocols consisted of a progesterone intravaginal device fitted for five days, along with the administration of different combinations of gonadotropin releasing hormone, equine chorionic gonadotropin and a single or double dose (24 h apart) of prostaglandin F2α. In Experiment I, the data were derived from 232 lactating cows. Binary logistic regression identified no effects of treatment on ovulation failure or multiple ovulation 10 days post artificial insemination (AI). Based on the odds ratio, the likelihood of ovulation failure was lower (by a factor of 0.1) in cows showing at least one corpus luteum (CL) upon treatment than in cows lacking a CL; repeat breeders (> 3 AI) and cows with multiple CLs at treatment showed lower (by a factor of 0.44) and higher (by a factor of 9.0) risks of multiple ovulation, respectively, than the remaining animals. In Experiment II, the data were derived from 5173 AIs. The independent variable treatment failed to affect the conception rate 28–34 days post AI, twin pregnancy or early fetal loss 58–64 days post AI. The results of this study demonstrate the efficacy of 5-day progesterone-based protocols for FTAI. All four protocols examined were able to induce ovulation in both cyclic and non-cyclic animals so that FTAI returned a similar pregnancy rate to spontaneous estrus. Our results suggest that the ovarian response and fertility resulting from each treatment are due more to the effect of ovarian structures at treatment than to the different combinations of hormones investigated.

  3. Expression of the GnRH and GnRH receptor (GnRH-R) genes in the hypothalamus and of the GnRH-R gene in the anterior pituitary gland of anestrous and luteal phase ewes.

    Ciechanowska, Magdalena; Lapot, Magdalena; Malewski, Tadeusz; Mateusiak, Krystyna; Misztal, Tomasz; Przekop, Franciszek


    Data exists showing that seasonal changes in the innervations of GnRH cells in the hypothalamus and functions of some neural systems affecting GnRH neurons are associated with GnRH release in ewes. Consequently, we put the question as to how the expression of GnRH gene and GnRH-R gene in the hypothalamus and GnRH-R gene in the anterior pituitary gland is reflected with LH secretion in anestrous and luteal phase ewes. Analysis of GnRH gene expression by RT-PCR in anestrous ewes indicated comparable levels of GnRH mRNA in the preoptic area, anterior and ventromedial hypothalamus. GnRH-R mRNA at different concentrations was found throughout the preoptic area, anterior and ventromedial hypothalamus, stalk/median eminence and in the anterior pituitary gland. The highest GnRH-R mRNA levels were detected in the stalk/median eminence and in the anterior pituitary gland. During the luteal phase of the estrous cycle in ewes, the levels of GnRH mRNA and GnRH-R mRNA in all structures were significantly higher than in anestrous ewes. Also LH concentrations in blood plasma of luteal phase ewes were significantly higher than those of anestrous ewes. In conclusion, results from this study suggest that low expression of the GnRH and GnRH-R genes in the hypothalamus and of the GnRH-R gene in the anterior pituitary gland, amongst others, may be responsible for a decrease in LH secretion and the anovulatory state in ewes during the long photoperiod.

  4. Study of Raman Spectroscopy on Phase Relations of CaCO3 at High Temperature and High Pressure

    Li, M.; Zheng, H.; Duan, T.


    Laser Raman Spectroscopy was used to study phase relations between calcite I, calcite II and aragonite at high pressure and high temperature. The experiment was performed in an externally heated Basselt type diamond anvil cell (DAC). Natural calcite (calcite I) was used as starting mineral. The sample and a small chip of quartz were loaded in a cavity (300 μm in diameter and 250 μm in depth) in a rhenium gasket. The Na2CO3 aqueous solution of 1mol/L was also loaded as a pressure medium to yield hydrostatic pressure. The whole assembly was pressurized first and then heated stepwise to 400°C. Pressure and temperature in the chamber were determined by the shift of Raman band at 464 cm-1 of quartz and by NiCr-NiSi thermocouple, respectively. The Raman spectra were measured by a Renishaw 1000 spetrometer with 50 mW of 514.5nm argon-ion laser as the excitation light source. The slit width was 50 μm and the corresponding resolution was ±1 cm-1. From the experiments, we observed the phase transitions between calcite I and calcite II, calcite I and aragonite, calcite II and aragonite, respectively. Our data showed a negative slope for the boundary between calcite I and calcite II, which was similar to Bridgman's result, although Hess et al. gave a positive slope. The boundary with a negative slope for calcite II and aragonite was also defined, which had never been done before. And all these data can yield a more complete phase diagram of CaCO3 than the studies of Hess et al. and Suito et al.Reference:Bridgeman P.

  6. A Proof-of-Concept Clinical Trial of A Single Luteal Use of Long-Acting Gonadotropin-Releasing Hormone Antagonist Degarelix in Controlled Ovarian Stimulation for In Vitro Fertilization: Long Antagonist Protocol

    Evangelos G. Papanikolaou


    Full Text Available IntroductionA drawback of gonadotropin-releasing hormone (GnRH antagonist protocols in in vitro fertilization (IVF is that they have limited flexibility in cycle programming. This proof of concept study explored the efficacy of a single-dose, long-acting GnRH antagonist IVF protocol. Trial registration number is NCT03240159, retrospectively registered on March 08, 2017.Materials and methodsThe efficacy of a single-dose long-acting antagonist, degarelix, was explored initially in healthy donors and subsequently in infertile patients. In the first part, five healthy oocyte donors underwent ovarian stimulation with this new protocol: in the late luteal phase, at day 24, a bolus injection of degarelix was administered subcutaneously to control the LH surge in the follicular phase. Ovarian stimulation with gonadotropins was initiated subsequently from day 7 to day 10. End points were first to inhibit the LH surge later in the follicular phase and, second, to retrieve mature oocytes for IVF. In the second part, five infertile women received the same bolus injection of degarelix administered during the luteal phase at day 24. Different gonadotropin starting days (day 2 through day 8 were tested in order to observe possible differences in ovarian stimulation. In these infertile patients, fresh embryo transfers were performed to assess the pregnancy efficacy of this protocol on pregnancy outcomes and to address any possible negative effects on endometrium receptivity.ResultsIn the first part of the study, all donors were effectively downregulated with a single luteal dose of 0.5 ml of degarelix for up to 22 days until the final oocyte maturation triggering day. Mature oocytes were retrieved after 36 h from all patients and all produced 2–7 blastocysts. In the second part, all five infertile patients achieved sufficient LH downregulation and completed ovarian stimulation without any LH surge. All patients (except one with freeze all strategy had

  7. Concentrations of testosterone, luteal hormone and prolactin in the serum as well as comparisons of sensitivity between radioimmunoassays and enzyme assays for the detection of acid prostate phosphatase in the presence of carcinomas of the prostate

    Vopelius-Feldt, F. von.


    The relationship between carcinomas of the prostate and the plasma levels of testosterone, luteal hormone and prolactin as well as the possible influence of these neoplasms on the testosterone binding capacity and free testosterone index are investigated for various tumour stages and degrees of histological differentiation, in connection with several forms of local therapy as well as a variety of contrasexual methods. The sensitivity of enzyme assays and radioimmunoassays for the detection of acid prostate phosphatase is evaluated within the framework of this study. (MBL) [de

  8. A Comparative Study of Continental vs. Intraoceanic Arc Mantle Melting: Experimentally Determined Phase Relations of Hydrous, Primitive Melts

    Weaver, S.; Johnston, A.; Wallace, P. J.


    It is widely recognized that H2O and other volatiles play a crucial role in mantle melting in subduction zones. This work is a comparative study focused on determining the H2O-undersaturated, near-liquidus phase relations for two primitive subduction related compositions with the goal of determining the P-T-H2O conditions of mantle melting beneath arcs. These samples, JR-28, a calc-alkaline basalt from Volcan Jorullo, Mexico, and ID-16, a tholeiitic basalt from Okmok Volcano, Aleutian Islands, have major element compositions that indicate they are primary, mantle-derived melts. H2O-undersaturated piston cylinder experiments have been carried out at upper mantle pressures and temperatures (1.0-2.0 GPa and 1100-1350°C). The near-liquidus mineralogy of these two compositions has been mapped in P-T- H2O space in order to constrain the conditions under which these melts are multiply saturated with a mantle residue (lherzolite or harzburgite). Previous studies of dissolved volatiles in olivine-hosted melt inclusions have provided an estimate of pre-eruptive H2O-contents for JR-28 at ≥5 wt% H2O and experiments have been carried out accordingly. Preliminary results for JR-28 at 5 wt% H2O show olivine ± Cr-rich spinel on the liquidus at 1.0 GPa and enstatite as the liquidus phase at higher pressures (1.3 to 2.0 GPa). Ca-rich pyroxene appears in only one experiment 50°C below the liquidus at 1.5 GPa. These data show that JR-28 melts are multiply saturated with a harzburgite assemblage at ~1175°C and ~1.2 GPa at 5 wt% H2O. Experiments at 7 wt% H2O show similar results, although the olivine/Cr-spinel stability field expands at the expense of the enstatite stability field. Consequently, the olivine-enstatite cotectic is shifted to higher pressures and slightly cooler temperatures. The relatively high SiO2 content in the bulk rock (~52 wt% SiO2) supports the hypothesis that JR-28 last equilibrated with a depleted or harzburgite residue rather than a more fertile mantle

  9. Early psychosis symptoms

    Naqvi, H.A.; Hussain, S.; Islam, M.


    Objective: To determine the prodromal symptoms of schizophrenia in the pathways to help-seeking. Study Design: A cross-sectional study. Place and Duration of Study: The Department of Psychiatry, the Aga Khan University, Karachi, from 2008 to 2009. Methodology: A total of 93 patients were interviewed in the pathways to care of schizophrenia. The diagnosis was based on ICD-10 criteria. The pathways to care were assessed through a semi-structured questionnaire. The onset, course and symptoms of psychosis were assessed through Interview for Retrospective Assessment at Age at Onset of Psychosis (IROAS). Results: Fifty five (59%) participants were male while 41% (n=38%) were female. Using IROAS, 108 symptoms were identified as concerning behaviour. Alternatively, 60 (55%) concerning behaviours were reported in the open-ended inquiry of the reasons for help seeking as assessed by the pathways to care questionnaire with a statistically significant difference between most symptoms category. The difference was most pronounced (p < 0.001) for depressed mood (66%), worries (65%), tension (63%), withdrawal/mistrust (54%) and loss of self-confidence (53%). Thought withdrawal (22%) and passivity (15%) were elicited only through structured interview (IROAS). When symptoms were categorized together, about 83% of the subjects presented with affective and non-specific prodromal symptoms. Roughly, 10% of the subjects presented with positive symptoms and 3% presented with the negative symptoms of psychosis. The non-specific, affective symptoms appear to predominate the prodromal phase of the illness. Conclusion: Prodromal symptoms of schizophrenia include non-specific, affective symptoms. Attention needs to be paid on identifying the prodromal symptoms and change in social functioning in order to identify those who are at risk of long term psychosis. (author)

  10. Influence of a low-carbohydrate diet on thermoregulatory responses to exercise in women during follicular and luteal phase of the menstrual cycle

    I Pokora


    Full Text Available The aim of this study was to examine the effects of a low-carbohydrate diet on thermoregulatory responses to exercise in women during follicular (F and luteal (L phase of the menstrual cycle. Ten subjects performed a graded bicycle exercise in a thermoneutral environment (23oC, 52-60% relative humidity. Women were tested after consuming, for 3 days, a control diet (C: 60% carbohydrates, 20% fat, 20% protein and after that a low-carbohydrate diet (LCHO: 50% fat, 35% protein and 5% carbohydrates, in each phase of the menstrual cycle. Tympanic temperature (Tty, mean skin temperature (Tsk, electrical skin resistance (ESR, oxygen uptake (VO2, heart rate (HR as well as blood β-hydroxybutyrate acid (β-HB, glucose (Glu and lactate (LA concentrations were measured. On the basis of ESR, dynamics of sweating was estimated. No differences in Tty and Tsk were found between the C and LCHO during exercise tests. However, Tty was significantly higher during L than F phase. Delay time for sweating was shorter after LCHO (F: 10.8 vs 9.4 min, P<0.05, L: 9.9 vs 9.3 N.S., but temperature threshold for this reaction was unchanged (L: 37.22 vs 37.37 and F: 36.91 vs 36.94 oC. Sweating sensitivity was greater after LCHO during both F and L. Resting blood Glu and LA concentrations were similar in women after C and LCHO diet. Before exercise β-HB level was F: 0.45, L: 0.35 mM after LCHO and F: 0.08, L: 0.09 mM after C diet (P<0.05, respectively. At rest and during exercise HR was significantly higher after LCHO diet in women during F phase. In submaximal exercise loads VO2 after LCHO diet were significantly higher than after C diet in all women. It was concluded that the low-carbohydrate diet ingested by young women in both phases of the menstrual cycle have no effect on body temperature, however, it affects heat dissipation mechanism during exercise.

    Repeat breeding directly affects reproductive efficiency in cattle due to an increase in services per conception and calving interval. This study aimed to investigate whether changes in endometrial gene expression profile are involved in repeat breeding in cows. Differential gene expression profiles of the endometrium were investigated during the mid-luteal phase of the estrous cycle between repeat breeder (RB) and non-RB cows using microarray analysis. The caruncular (CAR) and intercaruncular (ICAR) endometrium of both ipsilateral and contralateral uterine horns to the corpus luteum were collected from RB (inseminated at least three times but not pregnant) and non-RB cows on Day 15 of the estrous cycle (4 cows/group). Global gene expression profiles of these endometrial samples were analyzed with a 15 K custom-made oligo-microarray for cattle. Immunohistochemistry was performed to investigate the cellular localization of proteins of three identified transcripts in the endometrium. Microarray analysis revealed that 405 and 397 genes were differentially expressed in the CAR and ICAR of the ipsilateral uterine horn of RB, respectively when compared with non-RB cows. In the contralateral uterine horn, 443 and 257 differentially expressed genes were identified in the CAR and ICAR of RB, respectively when compared with non-RB cows. Gene ontology analysis revealed that genes involved in development and morphogenesis were mainly up-regulated in the CAR of RB cows. In the ICAR of both the ipsilateral and contralateral uterine horns, genes related to the metabolic process were predominantly enriched in the RB cows when compared with non-RB cows. In the analysis of the whole uterus (combining the data above four endometrial compartments), RB cows showed up-regulation of 37 genes including PRSS2, GSTA3 and PIPOX and down-regulation of 39 genes including CHGA, KRT35 and THBS4 when compared with non-RB cows. Immunohistochemistry revealed that CHGA, GSTA3 and PRSS2 proteins

  13. Influence of the current-phase relation on the critical-current-applied-magnetic-flux dependence in parallel-connected Josephson junctions

    Tsang, W.; Van Duzer, T.


    The form of the current-phase relations for the Josephson junctions is shown to have a significant influence on the relation I/sub c/(theta/sub a/) between critical current and applied flux for two junctions connected in parallel in a superconducting circuit. The observed one-flux-quantum periodicity and inversion symmetry of the I/sub c/(theta/sub a/) relation are shown to result from the fact that the current-phase, i-phi, relations of the junctions satisfy i (phi+2mπ) =i (phi) and i (-phi) =-i (phi), respectively. It is also shown that if the current-phase relations for the two junctions are different, an asymmetry appears in the I/sub c/(theta/sub a/)

    To compare IVF outcomes in poor-responder patients undergoing stimulation after luteal phase E(2) patch/GnRH antagonist (LPG) protocol versus microdose GnRH agonist protocol. Retrospective analysis. University-based IVF center. Forty-five women undergoing ovarian stimulation for IVF using the LPG protocol were compared with 76 women stimulated with the microdose GnRH agonist protocol from May 2005 to April 2006. Cancellation rate, number of oocytes retrieved, and clinical pregnancy rates. The mean number of oocytes (9.1 +/- 4.1 vs. 8.9 +/- 4.3) and mature oocytes (6.7 +/- 3.5 vs. 6.8 +/- 3.1) retrieved were similar, as were the fertilization rates (70.0% +/- 24.2% vs. 69.9% +/- 21.5%) and the number of embryos transferred (2.5 +/- 1.1 vs. 2.7 +/- 1.3). The cancellation rate was not significantly different between the groups (13/45, 28.9% vs. 23/76, 30.3%). Likewise, there were no significant differences among the implantation rate (15.0% vs. 12.5%), clinical pregnancy rate (43.3% vs. 45.1%), and ongoing pregnancy rate per transfer (33.3% vs. 26.0%) between both groups. This study demonstrates that the use of an E(2) patch and a GnRH antagonist during the preceding luteal phase in patients with a history of failed cycles can provide similar IVF outcomes when compared with the microdose GnRH agonist protocol.

  7. Premenstrual symptoms and posttraumatic stress disorder in Japanese high school students 9 months after the great East-Japan earthquake.

    Takeda, Takashi; Tadakawa, Mari; Koga, Shoko; Nagase, Satoru; Yaegashi, Nobuo


    On March 11, 2011, the Great East-Japan Earthquake occurred and a massive tsunami hit the northeastern coast of Japan. Catastrophic disasters such as earthquakes and war cause tremendous damage, not only physically but also mentally. Posttraumatic stress disorder (PTSD) is an anxiety disorder that occurs in the aftermath of a traumatic event. Premenstrual syndrome (PMS) is a cluster of psychological and somatic symptoms that are limited to the late luteal phase of the menstrual cycle. Premenstrual dysphoric disorder (PMDD) is considered a severe form of PMS. To determine the relationship between premenstrual symptoms and natural disaster-induced PTSD among Japanese adolescent girls, we conducted a cross-sectional study. Overall, 1489 high school students who belong to two high schools in Sendai, the largest city in northeastern Japan, were assessed 9 months after the earthquake. These schools are located inland, far from the seashore, and were not damaged by the tsunami. Premenstrual symptoms were assessed using the Premenstrual Symptoms Questionnaire, and PTSD symptoms were assessed using the Japanese-language version of Impact of Event Scale-Revised, which is a widely used self-assessment questionnaire about PTSD symptoms. We analyzed the data of 1,180 girls who completed the questionnaires and 118 girls (10.0%) were classified as having PTSD. The prevalence rates of PMDD and moderate to severe PMS increased according to the comorbidity of PTSD (p PMS/PMDD and natural disaster-induced PTSD. The comorbidity of PMS/PMDD and PTSD may complicate the follow-up of both conditions.

  15. Respiratory symptoms of megaesophagus

    Fabio Di Stefano


    Full Text Available Megaesophagus as the end result of achalasia is the consequence of disordered peristalsis and the slow decompensation of the esophageal muscular layer. The main symptoms of achalasia are dysphagia, regurgitation, chest pain and weight loss, but respiratory symptoms, such as coughing, particularly when patients lie in a horizontal position, may also be common due to microaspiration. A 70-year old woman suffered from a nocturnal cough and shortness of breath with stridor. She reported difficulty in swallowing food over the past ten years, but had adapted by eating a semi-liquid diet. Chest X-ray showed right hemithorax patchy opacities projecting from the posterior mediastinum. Chest computed tomography scan showed a marked dilatation of the esophagus with abundant food residues. Endoscopy confirmed the diagnosis of megaesophagus due to esophageal achalasia, excluding other causes of obstruction, such as secondary esophagitis, polyps, leiomyoma or leiomyosarcoma. In the elderly population, swallowing difficulties due to esophageal achalasia are often underestimated and less troublesome than the respiratory symptoms that are caused by microaspiration. The diagnosis of esophageal achalasia, although uncommon, should be considered in patients with nocturnal chronic coughs and shortness of breath with stridor when concomitant swallowing difficulties are present.

  16. Neurobiology Underlying Fibromyalgia Symptoms

    Marta Ceko


    Full Text Available Fibromyalgia is characterized by chronic widespread pain, clinical symptoms that include cognitive and sleep disturbances, and other abnormalities such as increased sensitivity to painful stimuli, increased sensitivity to multiple sensory modalities, and altered pain modulatory mechanisms. Here we relate experimental findings of fibromyalgia symptoms to anatomical and functional brain changes. Neuroimaging studies show augmented sensory processing in pain-related areas, which, together with gray matter decreases and neurochemical abnormalities in areas related to pain modulation, supports the psychophysical evidence of altered pain perception and inhibition. Gray matter decreases in areas related to emotional decision making and working memory suggest that cognitive disturbances could be related to brain alterations. Altered levels of neurotransmitters involved in sleep regulation link disordered sleep to neurochemical abnormalities. Thus, current evidence supports the view that at least some fibromyalgia symptoms are associated with brain dysfunctions or alterations, giving the long-held “it is all in your head” view of the disorder a new meaning.

  18. Induced endometrial trauma (endometrial scratch) in the mid-luteal menstrual cycle phase preceding first cycle IVF/ICSI versus usual IVF/ICSI therapy: study protocol for a randomised controlled trial.

    Pye, Clare; Chatters, Robin; Cohen, Judith; Brian, Kate; Cheong, Ying C; Laird, Susan; Mohiyiddeen, Lamiya; Skull, Jonathan; Walters, Stephen; Young, Tracey; Metwally, Mostafa


    Endometrial trauma commonly known as endometrial scratch (ES) has been shown to improve pregnancy rates in women with a history of repeated implantation failure undergoing in vitro fertilisation (IVF), with or without intracytoplasmic sperm injection (ICSI). However, the procedure has not yet been fully explored in women having IVF/ICSI for the first time. This study aims to examine the effect of performing an ES in the mid-luteal phase prior to a first-time IVF/ICSI cycle on the chances of achieving a clinical pregnancy and live birth. If ES can influence this success rate, there would be a significant cost saving to the National Health Service through decreasing the number of IVF/ICSI cycles necessary to achieve a pregnancy, increase the practice of single embryo transfer and consequently have a large impact on risks and costs associated with multiple pregnancies. This 30-month, UK, multicentre, parallel group, randomised controlled trial includes a 9-month internal pilot and health economic analysis recruiting 1044 women from 16 fertility units. It will follow up participants to identify if IVF/ICSI has been successful and live birth has occurred up to 6 weeks post partum. Primary analysis will be on an intention-to-treat basis. A substudy of endometrial samples obtained during the ES will assess the role of immune factors in embryo implantation. Main trial recruitment commenced on January 2017 and is ongoing.Participants randomised to the intervention group will receive the ES procedure in the mid-luteal phase of the preceding cycle prior to first-time IVF/ICSI treatment versus usual IVF/ICSI treatment in the control group, with 1:1 randomisation. The primary outcome is live birth rate after completed 24 weeks gestation. South Central-Berkshire Research Ethics Committee approved the protocol. Findings will be submitted to peer-reviewed journals and abstracts to relevant national and international conferences. ISRCTN23800982; Pre-results. © Article author

  20. Symptom management in Behcets disease.

    Ozel, Filiz; Tureyen, Aynur Esen; Aykar, Fisun Senuzun


    To determine the symptoms experienced by patients diagnosed with Behcet's Disease and how they cope with them. The qualitative study was conducted from September 2013 to March 2014 at Ege University Medical Faculty Hospital, Turkey, comprising patients having all symptoms of Behcet's Disease. Data was collected through semi-structured focus-group interview form. The findings were assessed using Theory of Unpleasant Symptoms and Symptom Management Theory. SPSS 20 and Nvivo 10 were used for data analysis. Of the 35 patients, 16(45.8%) were female and 19(54.2%) were male. The symptoms affected patients' lives, and the patients used either positive or negative symptom management strategies, leading to either positive or negative results during symptom management. Behcet's Disease patients needed effective symptom management.

  1. The Effect of Relaxation and Positive Self-Talk on Symptoms of Premenstrual Syndrome

    Kimiyaee Asadi


    Full Text Available Background Premenstrual syndrome (PMS is characterized by recurrent, moderate-to-severe affective, physical, and behavioral symptoms that develop during the luteal menstrual cycle and disappear within a few days of menstruation. Objectives This article aims to identify the effects of relaxation, positive self-talk, and a combination of relaxation and positive self-talk on premenstrual syndrome. Methods In this quasi-experimental study, 80 women with PMS disorder were selected using a simple random sampling method, in Hamadan, west of Iran. They were randomly divided into four groups. The first and second groups underwent positive self-talk and relaxation, respectively. The third group experienced positive self-talk and relaxation at the same time. The fourth group did not receive any treatment. The duration of treatment was 8 one-hour sessions. Data were collected using a PMS symptom severity questionnaire. All groups were followed up for six months after the intervention. Finally, data analysis was performed using SPSS version 18 for ANCOVA and Bonferroni tests. Results The results showed that compared to the control group, relaxation (23.2 and positive self-talk (21.25 treatment methods alone can reduce PMS (P < 0.001. On the other hand, a combined (relaxation + positive self-talk treatment method (13.75 was more effective in reducing PMS compared to relaxation or positive self-talk alone. Conclusions It seems that psychological therapy based on relaxation and positive self-talk can be significantly effective in reducing PMS.

  2. Follicular synchronization using transdermal estradiol patch and GnRH antagonists in the luteal phase; does it increase oocyte yield in poor responders to gonadotropin stimulation for in vitro fertilization (IVF)? A comparative study with microdose flare-up protocol.

    Ata, Baris; Zeng, Xing; Son, Weon Y; Holzer, Hananel; Tan, Seang L


    The aim of this retrospective study was to compare the oocyte yield with the luteal estradiol patch (LPA) - GnRH antagonist and microdose (MD) flare-up protocols in anticipated poor responders. Fifty-seven women who underwent IVF treatment following stimulation with LPA or MD protocols at McGill Reproductive Centre were matched for age and markers of ovarian reserve. Numbers of oocytes collected (6 vs 7), mature oocytes collected (5 vs 5), and oocyte maturation rates (72% vs 74%) were similar. The numbers of good quality embryos available (2 vs 1) and embryos transferred (3 vs 3) were likewise similar. Embryo implantation rate of 16.7% and clinical pregnancy rate of 38.9% achieved in the LPA group were almost 50% higher than the corresponding figures at 10.3% and 22.2% in the MD group; however, the differences were not statistically significant (p > 0.05 for all comparisons). Although the results do not suggest an increased oocyte yield or follicular synchronization with the LPA protocol, the observed trend toward higher embryo implantation and clinical pregnancy rates requires further research.

  3. Phase relations in the metal-rich portions of the phase system Pt-Ir-Fe-S at 1000 degrees C and 1100 degrees C

    Makovicky, E.; Karup-Møller, Sven


    Phase relations in the S-poor portions of the dry condensed Pt-Ir-Fe-S system were determined at 1000 degrees and 1100 degreesC with a particular emphasis on delineation of the solid solubility fields of the Pt-Ir-Fe alloys. At both temperatures, a broad field of gamma (Ir,Fe,Pt) alloy coexists...... with gamma-(Pt,Fe), Pt3Fe and PtFe which dissolve respectively at least 5.1, 29.3 and 24.0 at.% Ir at 1100 degreesC (2.2, 23.6 and less than or equal to 17.2 at.% Ir at 1000 degreesC). Gaps between the nearly Ir-free Pt-Fe alloys gamma (Pt,Fe), Pt3Fe s.s., PtFe s.s. and gamma (Fe,Pt) were estimated as 20......-23 at.%, 40-42 at.% and 54.2-similar to 57 at.% Fe at 1100 degreesC (18-23, 39.5-42.5 and 59-62 at.% Fe at 1000 degreesC). The first gap agrees with data from natural phases by Cabri et ni. (1996). The Fe-rich sulphide melt dissolves only traces of Pt and Ir; Fe1-xS dissolves up to 5.8 at.% Ir at 1100...

    Berdonosov, Peter S.; Charkin, Dmitri O.; Knight, Kevin S.; Johnston, Karen E.; Goff, Richard J.; Dolgikh, Valeriy A.; Lightfoot, Philip


    Several outstanding aspects of phase behaviour in the systems (Bi,Ln) 2 WO 6 and (Bi,Ln) 2 MoO 6 (Ln=lanthanide) have been clarified. Detailed crystal structures, from Rietveld refinement of powder neutron diffraction data, are provided for Bi 1.8 La 0.2 WO 6 (L-Bi 2 WO 6 type) and BiLaWO 6 , BiNdWO 6 , Bi 0.7 Yb 1.3 WO 6 and Bi 0.7 Yb 1.3 WO 6 (all H-Bi 2 WO 6 type). Phase evolution within the solid solution Bi 2- x La x MoO 6 has been re-examined, and a crossover from γ(H)-Bi 2 MoO 6 type to γ-R 2 MoO 6 type is observed at x∼1.2. A preliminary X-ray Rietveld refinement of the line phase BiNdMoO 6 has confirmed the α-R 2 MoO 6 type structure, with a possible partial ordering of Bi/Nd over the three crystallographically distinct R sites. - Graphical abstract: A summary of phase relations in the lanthanide-doped bismuth tungstate and bismuth molybdate systems is presented, together with some additional structural data on several of these phases

  5. Pore network modelling of heavy oil depressurization : a parametric study of factors affecting critical gas saturation and three-phase relative permeabilities

    Bondino, I.; McDougall, S.D. [Heriot-Watt Univ., Edinburgh, Scotland (United Kingdom); Hamon, G. [TotalFina Elf Exploration and Production (France)


    A review of how the bubble nucleation process affects the efficiency of heavy oil recovery was presented along with a discussion regarding a pore-scale simulator technique to depressurize heavy oil systems. A light oil depressurization simulation is also presented in which a straightforward instantaneous nucleation (IN) model and a more intricate progressive nucleation (PN) model have been used. Simulation results are compared to those derived from the heavy oil systems. The nucleation of bubbles, their growth by solute diffusion and expansion, plus the final stages of coalescence migration and production are the main steps in the depressurization process which were accounted for in a 3-phase simulator. The model can also determine the impact of bubble density and gas-oil diffusion coefficient on critical gas saturation and 3-phase relative permeability. The difference in results for light and heavy oils was also highlighted. In the first scenario, the evolution of gas was characterized by embryonic bubbles that are quickly and randomly nucleated once bubble-point pressure is reached. A stochastic algorithm was developed for PN from experimental observations. IN and PN observations were not necessarily contradictory. It was determined that the high interfacial tension of heavy oils leads to a more compact, capillary-dominated pattern of gas evolution compared to light oils, resulting in improved recoveries for heavy oil systems. 23 refs., 6 tabs., 23 figs.

  6. Subsolidus Phase Relations of the CaO-REOx-CuO Systems (RE = Eu, Tb, Dy, Ho, Er, Lu and Sc) at 900 °C in Air

    Grivel, Jean-Claude


    The subsolidus phase relations of the CaO-REOx-CuO systems (RE = Eu, Tb, Dy, Ho, Er, Lu and Sc) were investigated in air at 900 °C. The pseudo-ternary sections with RE = Tb, Dy, Ho, Er and Lu have a similar structure. They have in common with the RE = Eu system a solid solution of Ca0.833−xRExCuO2......+y composition but the system with RE = Eu differs by the presence of an Eu2CuO4 phase instead of RE2Cu2O5 for RE = Tb, Dy, Ho, Er and Lu. In contrast, the CaO-ScO1.5-CuO section does not contain a Ca0.833−xScxCuO2+y solid solution and is dominated by the CaSc2O4 phase, which has no equivalent...... in the other systems at 900 °C in air....

    The phase relations within the U-Al-Ge ternary system were studied for two isothermal sections, at 673 K for the whole Gibbs triangle and at 1173 K for the concentration range 25–100 at% U. The identification of the phases, their composition ranges and stability were determined by x-ray powder diffraction, scanning electron microscopy coupled to energy dispersive spectroscopy and differential thermal analysis. The tie-lines and the solubility domains were determined for the U-Ge and U-Al binaries, the UAl{sub 3}-UGe{sub 3} solid-solution and for the unique ternary intermediate phase U{sub 3}Al{sub 2−x}Ge{sub 3+x}. The experimental isopleth section of the pseudo-binary UAl{sub 3}-UGe{sub 3} reveals an isomorphous solid solution based on the Cu{sub 3}Au-type below the solidus. The U{sub 3}Al{sub 2−x}Ge{sub 3+x} solid solution extends for −0.1≤x≤1.35 and −0.2≤x≤1.5 at 673 K and 1173 K respectively. It crystallizes in the I-centered tetragonal symmetry. The reciprocal lattice of several compositions of the U{sub 3}Al{sub 2−x}Ge{sub 3+x} solid solution was examined by electron diffraction at room temperature, revealing the presence of a c-glide plane. Their crystal structure was refined by single crystal x-ray diffraction suggesting an isomorphous solid solution best described with the non-centrosymmetric space group I4cm in the paramagnetic domain. The magnetic measurements confirm the ferromagnetic ordering of the solid solution U{sub 3}Al{sub 2−x}Ge{sub 3+x} with an increase of Tc with the Al content. The thermal variation of the specific heat bear out the magnetic transitions with some delocalized character of the uranium 5f electrons. - Graphical abstract: The phase relations within the U-Al-Ge ternary system were experimentally assessed for two isothermal sections, at 673 K for the whole Gibbs triangle and at 1173 K for the concentration range 25–100 at% U.

  8. Phase relations in the Cabeza de Araya cordierite monzogranite, Iberian Massif: implications for the formation of cordierite in a crystal mush

    García Moreno, O.; Corretgé, L.G.; Holtz, F.; García-Arias, M.; Rodriguez, C.


    Experimental investigations and thermodynamic calculations of the phase relations of a cordierite-rich monzogranite from the Cabeza de Araya batholith (Cáceres, Spain) have been performed to understand the formation of cordierite. The experiments failed to crystallize cordierite in the pressure range 200-600MPa, in the temperature range 700-975ºC and for different water activities (melt water contents between 2 and 6 wt.%). In contrast, clinopyroxene and orthopyroxene (absent in the natural mineral rock assemblage), together with biotite, were observed as ferromagnesian assemblage in a wide range of experimental conditions. Thermodynamic calculations, using the software PERPLE{sub X}, describe the formation of cordierite only at 200 and 400MPa and very low water contents, and the amount of cordierite formed in the models is always below 3.5 vol.%. The results indicate that cordierite is not in equilibrium with the bulk rock compositions. The most probable explanation was that cordierite nucleated and crystallized from a melt that is not in equilibrium with part of the mineral assemblage present in the magma. This “non-reactive” mineral assemblage was mainly composed of plagioclase. The silicate melts from which cordierite crystallized was more Al-rich and K-rich than the silicate melt composition in equilibrium with the bulk composition. One possible process for the high Al content of the silicate melt is related to assimilation and partial melting of Al-rich metasediments. An exo-perictetic reaction is assumed to account for both textural and geochemical observations. On the other hand, hybridization processes typical for calc-alkaline series can also explain the high proportions of “non-reactive” minerals observed in relatively high temperature magmas. This study clearly demonstrates that silicate melts in a crystal mush can depart significantly from the composition of melt that should be in equilibrium with the bulk solid assemblage.

    Steady-state phase relations in the system UO/sub 2 + x/-CeO 2 -ZrO 2 -ThO 2 were determined for application to phase relations in the high-level crystalline ceramic nuclear waste form Supercalcine-Ceramics. Samples were treated at 1200 0 C at an oxygen partial pressure of 0.21 atm and a total pressure of 1 atm. Phase assemblages were found to be composed of cubic solid solutions of the flourite structure type, solid solutions based on ZrO 2 , and orthorhombic solid solutions based on U 3 O 8

  11. Non-contraceptive oestrogen-containing preparations for controlling symptoms of premenstrual syndrome.

    Naheed, Bushra; Kuiper, Jan Herman; Uthman, Olalekan A; O'Mahony, Fidelma; O'Brien, Patrick Michael Shaughn


    Premenstrual syndrome (PMS) is a psychological and somatic disorder of unknown aetiology, with symptoms typically including irritability, depression, mood swings, bloating, breast tenderness and sleep disturbances. About 3% to 10% of women who experience these symptoms may also meet criteria for premenstrual dysphoric disorder (PMDD). PMS symptoms recur during the luteal phase of the menstrual cycle and reduce by the end of menstruation. PMS results from ovulation and may be due to ovarian steroid interactions relating to neurotransmitter dysfunction. Premenstrual disorders have a devastating effect on women, their families and their work.Several treatment options have been suggested for PMS, including pharmacological and surgical interventions. The treatments thought to be most effective tend to fall into one of two categories: suppressing ovulation or correcting a speculated neuroendocrine anomaly.Transdermal oestradiol by patch, gel or implant effectively stops ovulation and the cyclical hormonal changes which produce the cyclical symptoms. These preparations are normally used for hormone therapy and contain lower doses of oestrogen than found in oral contraceptive pills. A shortened seven-day course of a progestogen is required each month for endometrial protection but can reproduce premenstrual syndrome-type symptoms in these women. To determine the effectiveness and safety of non-contraceptive oestrogen-containing preparations in the management of PMS. On 14 March 2016, we searched the following databases: the Cochrane Gynaecology and Fertility Group (CGF) Specialised Register; Cochrane Central Register of Studies (CRSO); MEDLINE; Embase; PsycINFO; CINAHL;; metaRegister of Controlled trials (mRCT); and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) Search Portal.

  15. Impact of ADHD symptoms on autism spectrum disorder symptom severity.

    Sprenger, Linda; Bühler, Eva; Poustka, Luise; Bach, Christiane; Heinzel-Gutenbrunner, Monika; Kamp-Becker, Inge; Bachmann, Christian


    Despite the official exclusion criteria for autism spectrum disorder (ASD) and attention deficit/hyperactivity disorder (ADHD) in the DSM-IV and ICD-10, patients with ASD often show ADHD symptoms. We aimed to examine the potential influence of ADHD symptoms on autistic psychopathology in a large sample of patients with ASD. We tested the hypothesis that patients with ASD and an additional ADHD (ASD+) would show a higher severity of autistic symptoms than those with ASD only (ASD-). We measured autistic symptoms using the autism diagnostic observation schedule (ADOS-G), the autism diagnostic interview (ADI-R), and the social responsiveness scale (SRS). To measure overall psychopathology and ADHD symptoms, we used the child behavior checklist (CBCL) and the ADHD rating scale (FBB-ADHS), respectively. Group differences between the ASD+ and the ASD- group (group division was conducted according to the results of the FBB-ADHS) were calculated using a univariate analysis of variance (ANOVA). The ASD+ group showed a greater severity of autistic symptoms than the ASD- group, measured by the SRS and the ADI-R. Especially in the social interaction subscale (ADI-R), a significantly higher symptom severity was found in the ASD+ group. No significant group differences were found regarding autistic symptoms measured by the ADOS-G. Patients with ASD and an additional ADHD expressed a stronger severity of autistic symptoms than patients with ASD only. According to our results, the possibility of a co-diagnosis of ADS and ADHD, as is being planned in the DSM-5, is in line with earlier studies, is highly reasonable, will simplify research, and have therapeutic implications.

    Phase relations in the pseudo ternary systems In2O3-TiO2-ZnO, In2O3-TiO2-CoO and In2O3-TiO2-NiO at 1200 °C in air were determined by means of a classic quenching method. In6Ti6BO22 (B: Zn, Co and Ni) which has the monoclinic In(Fe1/4Ti3/4)O27/8-type of structure with a 4-dimensional super space group exists in a stable form. There exist homologous phases In1+x(Ti1/2Zn1/2)1-xO3(ZnO)m (m: natural number, 0ternary system In2O3-TiO2-ZnO. All the ions are on the trigonal lattice points, the In(III) is in the octahedral coordination with the oxygen and the {Inx(Ti1/2Zn1/2)1-xZnm} is in the trigonalbipyramidal coordination with oxygen in the crystal structures of each homologous compound. They have R 3 bar m (No. 166) for m = odd or P63/mmc (No. 194) for m = even in space group. Lattice constants for each of the homologous compounds as a hexagonal setting and In6Ti6BO22 as the monoclinic system were determined by means of the powder X-ray diffraction method at room temperature. The temperature dependence of resistivity for In1+x(Ti1/2Zn1/2)1-x(ZnO)4 (0.15 ≤ x ≤ 1) showed semiconducting-like behavior for all samples examined at T(K) = 2-300. The resistivity increased systematically with decreasing x (0.7 ≤ x ≤ 1), and it was found that samples where x ≤ 0.7 became insulators. The optical band gap Eg (eV) of In1+x(Ti1/2Zn1/2)1-x(ZnO)4 has been estimated from the diffuse reflection spectra for the whole range of x (0.15 ≤ x ≤ 1). A minimum value of 2.0717 eV for x = 1 and a maximum one of 3.066 eV for x = 0.15 were observed. Dependence of the crystal structures of the InAO3(BO), In(Ti1/2B1/2)O3(B‧O) and stability of In6Ti6BO22 upon the constituent cations in the pseudo quaternary system In2O3-TiO2-A2O3-BO (A: Fe, Ga and Cr; B, B‧: Mg, Zn, Co, Ni, Ca and Sr) were discussed in terms of their ionic radii and site preference effects.

  1. Neuropsychiatric symptoms and celiac disease.

    Urban-Kowalczyk, Małgorzata; OEmigielski, Janusz; Gmitrowicz, Agnieszka


    Neuropsychiatric symptoms may represent an atypical manifestation of celiac disease that occur before a gastroenterological diagnosis is made. Some studies suggest that a gluten-free diet is effective in treating the depression, anxiety, and neurological complications associated with celiac disease. The article describes the case of a patient suffering from chronic, treatment-resistant symptoms of depression and anxiety. The diagnosis of celiac disease and introduction of an elimination diet caused a significant improvement in mental state and everyday functioning in the presenting patient. The presence of persistent anxiety and depressive symptoms, with a poor reaction to pharmacological treatment, indicates a need to identify somatic reasons for the underlying condition. It is important to remember that celiac disease can occur at any age, not only in childhood. The presence of this somatic cause of persistent depressive and anxiety symptoms should be considered in the diagnostic process in adults.

  13. Hope, Symptoms, and Palliative Care.

    Davis, Mellar P; Lagman, Ruth; Parala, Armida; Patel, Chirag; Sanford, Tanya; Fielding, Flannery; Brumbaugh, Anita; Gross, James; Rao, Archana; Majeed, Sumreen; Shinde, Shivani; Rybicki, Lisa A


    Hope is important to patients with cancer. Identifying factors that influence hope is important. Anxiety, depression, fatigue, and pain are reported to impair hope. The objective of this study was to determine whether age, gender, marital status, duration of cancer, symptoms, or symptom burden measured by the sum of severity scores on the Edmonton Symptom Assessment Scale (ESAS) correlated with hope measured by the Herth Hope Index (HHI). Patients with advanced cancer in a palliative care unit participated. Demographics including age, gender, marital status, cancer site, and duration of cancer were collected. Individuals completed the ESAS and HHI. Spearman correlation and linear regression were used to assess associations adjusting for gender (male vs female), age ( 12 months). One hundred and ninety-seven were participated in the study, of which 55% were female with a mean age of 61 years (standard deviation 11). Hope was not associated with gender, age, marital status, or duration of cancer. In univariable analysis, hope inversely correlated with ESAS score (-0.28), lack of appetite (-0.22), shortness of breath (-0.17), depression (-0.39), anxiety (-0.32), and lack of well-being (-0.33); only depression was clinically relevant. In multivariable analysis, total symptom burden weakly correlated with hope; only depression remained clinically significant. This study found correlation between symptom burden and hope was not clinically relevant but was so for depression. Among 9 ESAS symptoms, only depression had a clinically relevant correlation with hope.

  14. Adenomyosis and urinary system symptoms.

    Aydin, Gultekin Adanas; Yavuz, Arzu


    This study aims to investigate the presence and incidence of overactive bladder (OAB) syndrome in patients diagnosed with adenomyosis and to evaluate the impacts of urinary symptoms on the quality of life of the patients. A total of 108 individuals including 50 patients with adenomyosis and 58 controls who were admitted to the Obstetrics and Gynecology Department of Bursa, Cekirge State Hospital and Derince Training and Research Hospital between April 2015 and December 2015 were included. The Urogenital Distress Inventory (UDI-6) and Incontinence Impact Questionnaire (IIQ-7) were used to evaluate symptoms. Irritative urinary symptoms such as nocturia and frequency were seen more frequently in the adenomyosis group (p = 0.001 and p = 0.035). Overactive bladder symptoms were more common in the adenomyosis group (p = 0.0001). Our study showed that symptoms of urinary tract symptoms are common in patients with adenomyosis, which adversely affect the quality of life. Copyright © 2018 Elsevier B.V. All rights reserved.

  17. Wind turbines and idiopathic symptoms

    Blanes-Vidal, Victoria; Schwartz, Joel


    Whether or not wind turbines pose a risk to human health is a matter of heated debate. Personal reactions to other environmental exposures occurring in the same settings as wind turbines may be responsible of the reported symptoms. However, these have not been accounted for in previous studies. We...... investigated whether there is an association between residential proximity to wind turbines and idiopathic symptoms, after controlling for personal reactions to other environmental co-exposures. We assessed wind turbine exposures in 454 residences as the distance to the closest wind turbine (Dw) and number...... of wind turbines

  18. Betahistine for symptoms of vertigo.

    Murdin, Louisa; Hussain, Kiran; Schilder, Anne G M


    Vertigo is a symptom in which individuals experience a false sensation of movement. This type of dizziness is thought to originate in the inner ear labyrinth or its neural connections. It is a commonly experienced symptom and can cause significant problems with carrying out normal activities. Betahistine is a drug that may work by improving blood flow to the inner ear. This review examines whether betahistine is more effective than a placebo at treating symptoms of vertigo from different causes. To assess the effects of betahistine in patients with symptoms of vertigo from different causes. The Cochrane ENT Information Specialist searched the Cochrane ENT Trials Register; Central Register of Controlled Trials (CENTRAL 2015, Issue 8); PubMed; EMBASE; CINAHL; Web of Science;; ICTRP and additional sources for published and unpublished trials. We also contacted manufacturers and researchers in the field. The date of the search was 21 September 2015. We included randomised controlled trials of betahistine versus placebo in patients of any age with vertigo from any neurotological diagnosis in any settings. We used the standard methodological procedures expected by Cochrane. Our primary outcome was the proportion of patients with reduction in vertigo symptoms (considering together the intensity, frequency and duration those symptoms). We included 17 studies, with a total of 1025 participants; 12 studies were published (567 patients) and five were unpublished (458 patients). Sixteen studies including 953 people compared betahistine with placebo. All studies with analysable data lasted three months or less. The majority were at high risk of bias, but in some the risk of bias was unclear. One study, at high risk of bias, included 72 people with benign paroxysmal positional vertigo (BPPV) and compared betahistine with placebo; all patients also had particle repositioning manoeuvres. The studies varied considerably in terms of types of participants, their

  19. Symptoms and Symptom Clusters Identified by Adolescents and Young Adults With Cancer Using a Symptom Heuristics App.

    Ameringer, Suzanne; Erickson, Jeanne M; Macpherson, Catherine Fiona; Stegenga, Kristin; Linder, Lauri A


    Adolescents and young adults (AYAs) with cancer experience multiple distressing symptoms during treatment. Because the typical approach to symptom assessment does not easily reflect the symptom experience of individuals, alternative approaches to enhancing communication between the patient and provider are needed. We developed an iPad-based application that uses a heuristic approach to explore AYAs' cancer symptom experiences. In this mixed-methods descriptive study, 72 AYAs (13-29 years old) with cancer receiving myelosuppressive chemotherapy used the Computerized Symptom Capture Tool (C-SCAT) to create images of the symptoms and symptom clusters they experienced from a list of 30 symptoms. They answered open-ended questions within the C-SCAT about the causes of their symptoms and symptom clusters. The images generated through the C-SCAT and accompanying free-text data were analyzed using descriptive, content, and visual analyses. Most participants (n = 70) reported multiple symptoms (M = 8.14). The most frequently reported symptoms were nausea (65.3%), feeling drowsy (55.6%), lack of appetite (55.6%), and lack of energy (55.6%). Forty-six grouped their symptoms into one or more clusters. The most common symptom cluster was nausea/eating problems/appetite problems. Nausea was most frequently named as the priority symptom in a cluster and as a cause of other symptoms. Although common threads were present in the symptoms experienced by AYAs, the graphic images revealed unique perspectives and a range of complexity of symptom relationships, clusters, and causes. Results highlight the need for a tailored approach to symptom management based on how the AYA with cancer perceives his or her symptom experience. © 2015 Wiley Periodicals, Inc.

  9. Experimental study and thermodynamic modeling of the phase relation in the Fe-S-Si system with implications for the distribution of S and Si in a partially solidified core

    Tao, R.; Fei, Y.


    Planetary cooling leads to solidification of any initially molten metallic core. Some terrestrial cores (e.g. Mercury) are formed and differentiated under relatively reduced conditions, and they are thought to be composed of Fe-S-Si. However, there are limited understanding of the phase relations in the Fe-S-Si system at high pressure and temperature. In this study, we conducted high-pressure experiments to investigate the phase relations in the Fe-S-Si system up to 25 GPa. Experimental results show that the liquidus and solidus in this study are slightly lower than those in the Fe-S binary system for the same S concentration in liquid at same pressure. The Fe3S, which is supposed to be the stable sub-solidus S-bearing phase in the Fe-S binary system above 17 GPa, is not observed in the Fe-S-Si system at 21 GPa. Almost all S prefers to partition into liquid, while the distribution of Si between solid and liquid depends on experimental P and T conditions. We obtained the partition coefficient log(KDSi) by fitting the experimental data as a function of P, T and S concentration in liquid. At a constant pressure, the log(KDSi) linearly decreases with 1/T(K). With increase of pressure, the slopes of linear correlation between log(KDSi) and 1/T(K) decreases, indicating that more Si partitions into solid at higher pressure. In order to interpolate and extrapolate the phase relations over a wide pressure and temperature range, we established a comprehensive thermodynamic model in the Fe-S-Si system. The results will be used to constrain the distribution of S and Si between solid inner core and liquid outer core for a range of planet sizes. A Si-rich solid inner core and a S-rich liquid outer core are suggested for an iron-rich core.

  11. Respiratory symptoms in insect breeders.

    Harris-Roberts, J; Fishwick, D; Tate, P; Rawbone, R; Stagg, S; Barber, C M; Adisesh, A


    A number of specialist food suppliers in the UK breed and distribute insects and insect larvae as food for exotic pets, such as reptiles, amphibians and invertebrates. To investigate the extent of work-related (WR) symptoms and workplace-specific serum IgE in workers potentially exposed to a variety of biological contaminants, including insect and insect larvae allergens, endotoxin and cereal allergens at a UK specialist insect breeding facility. We undertook a study of respiratory symptoms and exposures at the facility, with subsequent detailed clinical assessment of one worker. All 32 workers were assessed clinically using a respiratory questionnaire and lung function. Eighteen workers consented to provide serum for determination of specific IgE to workplace allergens. Thirty-four per cent (11/32) of insect workers reported WR respiratory symptoms. Sensitization, as judged by specific IgE, was found in 29% (4/14) of currently exposed workers. Total inhalable dust levels ranged from 1.2 to 17.9 mg/m(3) [mean 4.3 mg/m(3) (SD 4.4 mg/m(3)), median 2.0 mg/m(3)] and endotoxin levels of up to 29435 EU/m(3) were recorded. Exposure to organic dusts below the levels for which there are UK workplace exposure limits can result in respiratory symptoms and sensitization. The results should alert those responsible for the health of similarly exposed workers to the potential for respiratory ill-health and the need to provide a suitable health surveillance programme.

    Sevim Akin


    Full Text Available Aim: The aim of this study was to investigate the prevalence of musculoskeletal manifestations in patients with thyroid dysfunction. Methods: One hundred and twenty-three patients (100 female, 23 male who visited the nuclear medicine department for thyroid gland scintigraphy were included in our study. According to thyroid hormone levels, patients were allocated into five categories: hyperthyroidism, subclinical hyperthyroidism, euthyroid, subclinical hypothyroidism, and hypothyroidism. Before neurological and musculoskeletal examinations, a standardized symptom questionnaire was completed including questions about sensory symptoms, muscle weakness, restricted joint mobility, musculoskeletal pain. Neurological examination, range of motion of joints, effusion or swelling of joints was assessed. Diagnosis of osteoarthritis was done by the clinical and radiological characteristics. The diagnosis of FMS was made according to criteria of American College of Rheumatology. According to the World Health Organization (WHO, a T-score ≤ -2.5 was classified as osteoporosis, whereas a T-score between -2.5 and -1.0 was classified as osteopenia. Thyroid status was determined by serum TSH levels. Results: Eighty-one percent of the patients were female (100 and 19% were male (23. Mean age of female patients was 49.99±15.27 years (range 20-87 and mean age of male patients was 61.8±12.33 years (range 34-88. When divided according to thyroid status, 21.1% (n=26 had hyperthyroidism, 21.1% (n=26 had subclinical hyperthyroidism, 49.6% (n=61 were euthyroid, 4.9% (n=6 had subclinical hypothyroidism and 3.3% (n=4 were hypothyroid. None of 59% of patients had any musculoskeletal diagnosis. Osteoporosis was the most common problem, affecting 23.7% of patients Conclusion: The presence of musculoskeletal symptoms in patients with goiter should be considered and investigated.

  3. Trauma Symptoms in Abused Children

    Parvaneh Mohammadkhani


    Full Text Available Objective: There are many traumatic events (including natural disasters, physical, psychological and sexual abuse that may befall children and there is clear evidence that such experiences can produce a plethora of negative psychological effects. Children’s exposure to such traumas has been associated with a wide variety of negative mental health outcomes, including anxiety and depression, post-traumatic stress and dissociation and anger and aggression. It seems that the impacts of traumatic events are significantly related to type and intensity of trauma. Materials & Method: Through a systematized clustral sampling 3042 male and female students from junior high school who were participated in a survey study for investigating point prevalence of child abuse, completed Trauma Symptoms Checklist for Children-Alternate Version (TSCC-A and Child Abuse Self-report Scale (CASRS. After recognition of abused children, they were compared based on trauma symptoms. TSCC-A is a self-report measure of post-traumatic distress and related psychological symptomatology in male and female children aged 8-16 years. It is useful in the evaluation of children who have experienced traumatic events, including physical and sexual assault, victimization by peers, major losses, the witnessing of violence done to others and natural disasters. TSCC-A makes no reference to sexual issues. CASRS is a self-report scale to assess child abuse and neglect with 38 items and four subscales (psychological abuse, neglect, physical and sexual abuse. Results: Considering the type of traumatic experiences, the results showed that abused children significantly received higher scores in scales and subscales of TSCC-A than nonabused group. They specially reported more symptoms (depression, anxiety, post-traumatic stress, anger and dissociation comparing normal children. Conclusion: It is concluded that the type and rate of traumatic event is related to intensity of symptomatology.

  12. Assessment of lower urinary tract symptoms in men by international prostate symptom score and core lower urinary tract symptom score.

    Fujimura, Tetsuya; Kume, Haruki; Nishimatsu, Hiroaki; Sugihara, Toru; Nomiya, Akira; Tsurumaki, Yuzuri; Miyazaki, Hideyo; Suzuki, Motofumi; Fukuhara, Hiroshi; Enomoto, Yutaka; Homma, Yukio


    Study Type - Therapy (symptom prevalence). Level of Evidence 2a. What's known on the subject? and What does the study add? The International Prostate Symptom Score (IPSS) has been most commonly used for the symptom assessment of men with lower urinary tract symptoms (LUTS). However, LUTS in men are so variable that they may not be fully captured by the IPSS questionnaire alone. This study has demonstrated that the Core Lower Urinary Tract Symptom Score (CLSS) questionnaire, which addresses 10 important symptoms, is an appropriate initial assessment tool for LUTS in men with various diseases/conditions. International Prostate Symptom Score (IPSS) has been commonly used to assess lower urinary tract symptoms (LUTS). We have recently developed Core Lower Urinary Tract Symptom Score (CLSS). The aim of this study is to compare IPSS and CLSS for assessing LUTS in men.  Consecutive 515 men fulfilled IPSS and CLSS questionnaires. IPSS QOL Index was used as the QOL surrogate. The clinical diagnoses were BPH (n = 116), BPH with OAB wet (n =80), prostate cancer (n = 128), prostatitis (n = 68), underactive bladder (n = 8), others (n = 72), and controls (e.g., occult blood) (n = 42). Simple statistics and predictability of poor QOL (QOL Index 4 or greater) were examined. All symptom scores were significantly increased in symptomatic men compared with controls. Scores of corresponding symptoms of two questionnaires were significantly correlated (r = 0.58-0.85, all P incontinence, slow stream, straining, incomplete emptying, bladder pain and urethral pain) as independent factors. The hazard ratios for bladder pain (2.2) and urgency incontinence (2.0) were among the highest. All the nine symptoms are addressed in CLSS, while three symptoms (urgency incontinence, bladder, and urethral pain) are dismissed in IPSS. CLSS questionnaire is more comprehensive than IPSS questionnaire for symptom assessment of men with various diseases/conditions, although both questionnaires can capture

  13. Vegan diet alleviates fibromyalgia symptoms.

    Kaartinen, K; Lammi, K; Hypen, M; Nenonen, M; Hanninen, O; Rauma, A L


    The effect of a strict, low-salt, uncooked vegan diet rich in lactobacteria on symptoms in 18 fibromyalgia patients during and after a 3-month intervention period in an open, non-randomized controlled study was evaluated. As control 15 patients continued their omnivorous diet. The groups did not differ significantly from each other in the beginning of the study in any other parameters except in pain and urine sodium. The results revealed significant improvements in Visual analogue scale of pain (VAS) (p=0.005), joint stiffness (p=0.001), quality of sleep (p=0.0001), Health assessment questionnaire (HAQ) (p=0.031), General health questionnaire (GHQ) (p=0.021), and a rheumatologist's own questionnaire (p=0.038). The majority of patients were overweight to some extent at the beginning of the study and shifting to a vegan food caused a significant reduction in body mass index (BMI) (p=0.0001). Total serum cholesterol showed a statistically significant lowering (p=0.003). Urine sodium dropped to 1/3 of the beginning values (p=0.0001) indicating good diet compliance. It can be concluded that vegan diet had beneficial effects on fibromyalgia symptoms at least in the short run.

  14. Eating disorder symptoms and parenting styles.

    Haycraft, Emma; Blissett, Jackie


    This study aimed to examine associations between symptoms of eating disorders and parenting style, in a non-clinical sample. One hundred and five mothers completed self-report measures of eating disorder symptoms and parenting style. Higher levels of eating disorder symptoms were associated with more authoritarian and permissive parenting styles. Authoritative parenting was not significantly related to eating disorder symptoms. The findings demonstrate that eating disorder symptoms in non-clinical individuals are related to less adaptive parenting styles. These findings have potential implications for clinicians working with mothers with eating disorders. 2009 Elsevier Ltd. All rights reserved.

  15. Vitamins K2, K3 and K5 exert in vivo antitumor effects on hepatocellular carcinoma by regulating the expression of G1 phase-related cell cycle molecules.

    Kuriyama, Shigeki; Hitomi, Misuzu; Yoshiji, Hitoshi; Nonomura, Takako; Tsujimoto, Tatsuhiro; Mitoro, Akira; Akahane, Takami; Ogawa, Mutsumi; Nakai, Seiji; Deguchi, Akihiro; Masaki, Tsutomu; Uchida, Naohito


    A number of studies have shown that various vitamins K, specifically vitamin K2, possessed antitumor activity on various types of rodent- and human-derived neoplastic cell lines. However, there are only a small number of reports demonstrating in vivo antitumor effects of vitamins K. Furthermore, the mechanism of antitumor effects of vitamins K still remains to be examined. In the present study, we examined the antitumor effects of vitamins K2, K3 and K5 on PLC/PRF/5 human hepatocellular carcinoma (HCC) cells in vivo. Furthermore, to examine the mechanism of antitumor actions of these vitamins K, mRNA expression levels of various G1 phase-related cell cycle molecules were evaluated by using a real-time reverse transcription-polymerase chain reaction (RT-PCR) method. HCC-bearing animals were produced by implanting PLC/PRF/5 cells subcutaneously into athymic nude mice, and drinking water containing vitamin K2, K3 or K5 was given to the animals. Treatments with vitamins K2, K3 and K5 were shown to markedly inhibit the growth of HCC tumors. To examine the mechanism of in vivo antitumor effects of vitamins K, total RNA was extracted from HCC tumors, and the expression of G1 phase-related cell cycle molecules was quantitatively examined. Real-time RT-PCR demonstrated that the expression of the cell cycle-driving molecule, cyclin-dependent kinase 4 (Cdk4), in HCC was significantly reduced by the treatments with vitamin K2, K3 and K5. Conversely, the expression of the cell cycle-suppressing molecules, Cdk inhibitor p16INK4a and retinoblastoma, in HCC was significantly enhanced by the treatments with vitamins K2, K3 and K5. These results indicate that vitamins K2, K3 and K5 exert antitumor effects on HCC by regulating the expression of G1 phase-related cell cycle molecules. These results also indicate that vitamins K2, K3 and K5 may be useful agents for the treatment of patients with HCC.

    Objective To examine self-reported symptoms by the patients receiving cancer therapy, and find out the symptoms that should be coped with and managed during the treatment. Methods A pilot study was conducted on self-reported symptoms on 185 patients receiving chemotherapy and/or radiotherapy for different cancers. The Therapy-Related Symptoms Checklist (TRSC) was used. Results Severe symptoms on the TRSC subscales: loss of appetite,feeling sluggish, weight loss, nausea and hair loss, were reported by the patients. The frequently reported symptoms by those on chemotherapy were nausea, feeling sluggish, weight loss, vomiting, and taste change. The frequently reported symptoms by those on radiotherapy were feeling sluggish, weight loss, loss of appetite, difficult sleeping, and changing taste. The symptoms of loss of appetite, feeling sluggish, weight loss, hair loss, and nausea were both frequently reported by those on radiotherapy and those on chemotherapy. Conclusion Symptom monitoring may be facilitated by TRSC, based on the severity and frequency of reported symptoms, more patients and caregivers could know which symptoms should be preferential interventions.

  17. Symptom structure of PTSD following breast cancer.

    Cordova, M J; Studts, J L; Hann, D M; Jacobsen, P B; Andrykowski, M A


    Identification of posttraumatic stress disorder (PTSD) symptoms and diagnoses in survivors of cancer is a growing area of research, but no published data exist regarding the symptom structure of PTSD in survivors of malignant disease. Findings from investigations of the PTSD symptom structure in other trauma populations have been inconsistent and have not been concordant with the re-experiencing, avoidance/numbing, and arousal symptom clusters specified in DSM-IV. The present study employed confirmatory factor analysis to evaluate the extent to which the implied second-order factor structure of PTSD was replicated in a sample of 142 breast cancer survivors. PTSD symptoms were measured using the PTSD Checklist--Civilian Version (PCL-C). Fit indices reflected a moderate fit of the symptom structure implied by the DSM-IV. These findings provide some tentative support for the DSM-IV clustering of PTSD symptoms and for the validity of cancer-related PTSD.

  18. Asthma symptoms in obese adults

    Ulrik, Charlotte Suppli


    The association between asthma and obesity is well-described, but not straightforward, and according to current guidelines asthma control is more difficult to achieve in obese patients. The currently available studies evaluating response to pharmacological asthma therapy in obese patients show...... that these patients have an altered, in general less favorable, response to both reliever and controller medication compared to normal weight patients. However, at present, the limited available evidence precludes evidence-based recommendations. The 'obesity-related asthma' phenotype has different characteristics......, including association with atopy and type of airway inflammation, compared to 'classic' asthma. Furthermore, weight loss in patients with this phenotype leads to an improvement in symptoms, lung function, and airway responsiveness, as well as a reduction in medication utilization and hospital admissions...

  19. First rank symptoms for schizophrenia.

    Soares-Weiser, Karla; Maayan, Nicola; Bergman, Hanna; Davenport, Clare; Kirkham, Amanda J; Grabowski, Sarah; Adams, Clive E


    Early and accurate diagnosis and treatment of schizophrenia may have long-term advantages for the patient; the longer psychosis goes untreated the more severe the repercussions for relapse and recovery. If the correct diagnosis is not schizophrenia, but another psychotic disorder with some symptoms similar to schizophrenia, appropriate treatment might be delayed, with possible severe repercussions for the person involved and their family. There is widespread uncertainty about the diagnostic accuracy of First Rank Symptoms (FRS); we examined whether they are a useful diagnostic tool to differentiate schizophrenia from other psychotic disorders. To determine the diagnostic accuracy of one or multiple FRS for diagnosing schizophrenia, verified by clinical history and examination by a qualified professional (e.g. psychiatrists, nurses, social workers), with or without the use of operational criteria and checklists, in people thought to have non-organic psychotic symptoms. We conducted searches in MEDLINE, EMBASE, and PsycInfo using OvidSP in April, June, July 2011 and December 2012. We also searched MEDION in December 2013. We selected studies that consecutively enrolled or randomly selected adults and adolescents with symptoms of psychosis, and assessed the diagnostic accuracy of FRS for schizophrenia compared to history and clinical examination performed by a qualified professional, which may or may not involve the use of symptom checklists or based on operational criteria such as ICD and DSM. Two review authors independently screened all references for inclusion. Risk of bias in included studies were assessed using the QUADAS-2 instrument. We recorded the number of true positives (TP), true negatives (TN), false positives (FP), and false negatives (FN) for constructing a 2 x 2 table for each study or derived 2 x 2 data from reported summary statistics such as sensitivity, specificity, and/or likelihood ratios. We included 21 studies with a total of 6253 participants

  20. Parents' Reports of Children's Internalizing Symptoms: Associations with Parents' Mental Health Symptoms and Substance Use Disorder.

    Kelley, Michelle L; Bravo, Adrian J; Hamrick, Hannah C; Braitman, Abby L; White, Tyler D; Jenkins, Jennika


    This brief report examined the unique associations between parents' ratings of child internalizing symptoms and their own depression and anxiety in families with parental substance use disorder (SUD). Further, we examined whether parental SUD (father only, mother only, both parents) was related to discrepancy in mothers' and fathers' reports of children's internalizing symptoms. Participants were 97 triads (fathers, mothers) in which one or both parents met criteria for SUD. Polynomial regression analyses were conducted to examine whether father-mother reports of child internalizing symptoms had unique associations with parents' own symptoms of depression and anxiety while controlling for child gender, child age, and SUD diagnoses. Controlling for fathers' symptoms and other covariates, mothers experiencing more depression and anxiety symptoms reported more symptoms of child internalizing symptoms than did fathers. Mothers' and fathers' SUD was associated with higher anxiety symptoms among mothers after controlling for other variables. A second set of polynomial regressions examined whether father-mother reports of child internalizing symptoms had unique associations with parents' SUD diagnoses while controlling for child gender and child age. After controlling for mothers' symptoms and other covariates, parents' reports of children's internalizing symptoms were not significantly associated with either parent's SUD or parental SUD interactions (i.e., both parents have SUD diagnoses). Taken together, mothers' ratings of children's internalizing symptoms may be accounted for, in part, by her reports of depression and anxiety symptoms.

    Souza, Rosely Almeida; Desani da Costa, Gislaine; Yamashita, Cintia Hitomi; Amendola, Fernanda; Gaspar, Jaqueline Correa; Alvarenga, Márcia Regina Martins; Faccenda, Odival; Oliveira, Maria Amélia de Campos


    To classify families of elderly with depressive symptoms regarding their functioning and to ascertain the presence of an association between these symptoms, family functioning and the characteristics of the elderly. This was an observational, analytical, cross-sectional study performed with 33 teams of the Family Health Strategy in Dourados, MS. The sample consisted of 374 elderly divided into two groups (with and without depressive symptoms). The instruments for data collection were a sociodemographic instrument, the GeriatricDepression Scale (15 items) and the Family Apgar. An association was observed between depressive symptoms and family dysfunction, female gender, four or more people living together, and physical inactivity. The functional family may represent effective support for the elderly with depressive symptoms, because it offers a comfortable environment that ensures the well-being of its members. The dysfunctional family can barely provide necessary care for the elderly, which can exacerbate depressive symptoms.

  6. "Negative symptoms"secondary to intracranial tumor

    Natasha Kate


    Full Text Available Intracranial tumors are increasingly common in the elderly population. They may present with varied symptoms, some of which may be psychiatric in nature. In patients with known psychiatric disorders, these symptoms may be misattributed resulting in a delay in diagnosis and management. We present a case of an elderly female with paranoid schizophrenia and new onset symptoms secondary to intracranial tumor, which were initially misdiagnosed.

  8. Dissociative symptoms and neuroendocrine dysregulation in depression.

    Bob, Petr; Fedor-Freybergh, Peter; Jasova, Denisa; Bizik, Gustav; Susta, Marek; Pavlat, Josef; Zima, Tomas; Benakova, Hana; Raboch, Jiri


    Dissociative symptoms are traditionally attributed to psychological stressors that produce dissociated memories related to stressful life events. Dissociative disorders and dissociative symptoms including psychogenic amnesia, fugue, dissociative identity-disorder, depersonalization, derealization and other symptoms or syndromes have been reported as an epidemic psychiatric condition that may be coexistent with various psychiatric diagnoses such as depression, schizophrenia, borderline personality disorder or anxiety disorders. According to recent findings also the somatic components of dissociation may occur and influence brain, autonomic and neuroendocrine functions. At this time there are only few studies examining neuroendocrine response related to dissociative symptoms that suggest significant dysregulation of the hypothalamus-pituitary-adrenal (HPA) axis. The aim of the present study is to perform examination of HPA axis functioning indexed by basal cortisol and prolactin and test their relationship to psychic and somatoform dissociative symptoms. Basal cortisol and prolactin and psychic and somatoform dissociative symptoms were assessed in 40 consecutive inpatients with diagnosis of unipolar depression mean age 43.37 (SD=12.21). The results show that prolactin and cortisol as indices of HPA axis functioning manifest significant relationship to dissociative symptoms. Main results represent highly significant correlations obtained by simple regression between psychic dissociative symptoms (DES) and serum prolactin (R=0.55, p=0.00027), and between somatoform dissociation (SDQ-20) and serum cortisol (R=-0.38, p=0.015). These results indicate relationship between HPA-axis reactivity and dissociative symptoms in unipolar depressive patients that could reflect passive coping behavior and disengagement.

  9. The brief negative symptom scale: psychometric properties.

    Kirkpatrick, Brian; Strauss, Gregory P; Nguyen, Linh; Fischer, Bernard A; Daniel, David G; Cienfuegos, Angel; Marder, Stephen R


    The participants in the NIMH-MATRICS Consensus Development Conference on Negative Symptoms recommended that an instrument be developed that measured blunted affect, alogia, asociality, anhedonia, and avolition. The Brief Negative Symptom Scale (BNSS) is a 13-item instrument designed for clinical trials and other studies that measures these 5 domains. The interrater, test-retest, and internal consistency of the instrument were strong, with respective intraclass correlation coefficients of 0.93 for the BNSS total score and values of 0.89-0.95 for individual subscales. Comparisons with positive symptoms and other negative symptom instruments supported the discriminant and concurrent validity of the instrument.

  10. Frailty and Lower Urinary Tract Symptoms.

    Suskind, Anne M


    The incidence of both frailty and lower urinary tract symptoms, including urinary incontinence, overactive bladder, underactive bladder, and benign prostatic hyperplasia, increases with age. However, our understanding of the relationship between frailty and lower urinary tract symptoms, both in terms of pathophysiology and in terms of the evaluation and management of such symptoms, is greatly lacking. This brief review will summarize definitions and measurement tools associated with frailty and will also review the existing state of the literature on frailty and lower urinary tract symptoms in older individuals.

  11. Male hypogonadism: Symptoms and treatment

    Peeyush Kumar


    Full Text Available Male hypogonadism is a condition in which the body does not produce enough of the testosterone hormone; the hormone that plays a key role in masculine growth and development during puberty. There is a clear need to increase the awareness of hypogonadism throughout the medical profession, especially in primary care physicians who are usually the first port of call for the patient. Hypogonadism can significantly reduce the quality of life and has resulted in the loss of livelihood and separation of couples, leading to divorce. It is also important for doctors to recognize that testosterone is not just a sex hormone. There is an important research being published to demonstrate that testosterone may have key actions on metabolism, on the vasculature, and on brain function, in addition to its well-known effects on bone and body composition. This article has been used as an introduction for the need to develop sensitive and reliable assays for sex hormones and for symptoms and treatment of hypogonadism.

  13. A Structural Equation Model of HIV-related Symptoms, Depressive Symptoms, and Medication Adherence.

    Yoo-Jeong, Moka; Waldrop-Valverde, Drenna; McCoy, Katryna; Ownby, Raymond L


    Adherence to combined antiretroviral therapy (cART) remains critical in management of HIV infection. This study evaluated depression as a potential mechanism by which HIV-related symptoms affect medication adherence and explored if particular clusters of HIV symptoms are susceptible to this mechanism. Baseline data from a multi-visit intervention study were analyzed among 124 persons living with HIV (PLWH). A bifactor model showed two clusters of HIV-related symptom distress: general HIV-related symptoms and gastrointestinal (GI) symptoms. Structural equation modeling showed that both general HIV-related symptoms and GI symptoms were related to higher levels of depressive symptoms, and higher levels of depressive symptoms were related to lower levels of medication adherence. Although general HIV-related symptoms and GI symptoms were not directly related to adherence, they were indirectly associated with adherence via depression. The findings highlight the importance of early recognition and evaluation of symptoms of depression, as well as the underlying physical symptoms that might cause depression, to improve medication adherence.

  14. Symptom experience of Filipino American midlife women.

    Berg, J A; Taylor, D L


    The purpose of this study was to describe the perimenopausal symptom experience of Filipino American midlife women with particular emphasis upon estrogen-related menopause symptoms (day sweats, hot flashes, night sweats, and vaginal dryness). A cross-sectional, descriptive survey was used to generate symptom experience data for 165 Filipina Americans between the ages of 35 and 56 who self-identified as Filipina American and were English-language proficient. The community-based sample completed questionnaires composed of sample characteristic questions and a 51-item menstrual symptom checklist with menopause-related symptoms embedded in it. Sample characteristics and symptom experience were compared among age groups of 35 to 39 (n = 39), 40 to 44 (n = 40), 45 to 49 (n = 37), and 50 to 56 (n = 49) and by perimenopausal phase, defined as premenopausal (n = 85), transitional (n = 33), and menopausal/postmenopausal (n = 47). The most reported individual symptoms were "felt energetic" (86.1%) and "well-being" (83.6%). Estrogen-related menopause symptoms were reported as "vaginal dryness" (39.4%), "hot flashes" (37.6%), "day sweats" (27.9%), and "night sweats" (24.2%) by the total sample. Distress associated with estrogen-related menopause symptoms was reported by 17% (n = 28) of all women. Subjects' chi 2 tests indicated that 50-to-56-year-old women were more likely to report fatigue/sleep symptoms, physical symptoms, and estrogen-related menopause symptoms than all other age groups. When compared by perimenopausal phase, transitional women were more likely to report moderate or extreme severity for day sweats. Premenopausal women were more likely to report minimal or mild severity and women in the perimenopausal transition were more likely to report moderate or extreme severity on estrogen-related menopause symptoms. Filipino American midlife women appear to consider the perimenopausal transition in a positive light and experience little distress associated with

  19. Upper gastrointestinal symptoms in autoimmune gastritis

    Carabotti, Marilia; Lahner, Edith; Esposito, Gianluca; Sacchi, Maria Carlotta; Severi, Carola; Annibale, Bruno


    Abstract Autoimmune gastritis is often suspected for its hematologic findings, and rarely the diagnosis is made for the presence of gastrointestinal symptoms. Aims of this cross-sectional study were to assess in a large cohort of patients affected by autoimmune gastritis the occurrence and the pattern of gastrointestinal symptoms and to evaluate whether symptomatic patients are characterized by specific clinical features. Gastrointestinal symptoms of 379 consecutive autoimmune gastritis patients were systematically assessed and classified following Rome III Criteria. Association between symptoms and anemia pattern, positivity to gastric autoantibodies, Helicobacter pylori infection, and concomitant autoimmune disease were evaluated. In total, 70.2% of patients were female, median age 55 years (range 17–83). Pernicious anemia (53.6%), iron deficiency anemia (34.8%), gastric autoantibodies (68.8%), and autoimmune disorders (41.7%) were present. However, 56.7% of patients complained of gastrointestinal symptoms, 69.8% of them had exclusively upper symptoms, 15.8% only lower and 14.4% concomitant upper and lower symptoms. Dyspepsia, subtype postprandial distress syndrome was the most represented, being present in 60.2% of symptomatic patients. Univariate and multivariate analyses showed that age gastritis is associated in almost 60% of cases with gastrointestinal symptoms, in particular dyspepsia. Dyspepsia is strictly related to younger age, no smoking, and absence of anemia. PMID:28072728

  11. Prevalence of gastro-oesophageal reflux disease symptoms and reflux-associated respiratory symptoms in asthma


    Background Gastro-oesophageal reflux disease (GORD) symptoms are common in asthma and have been extensively studied, but less so in the Asian continent. Reflux-associated respiratory symptoms (RARS) have, in contrast, been little-studied globally. We report the prevalence of GORD symptoms and RARS in adult asthmatics, and their association with asthma severity and medication use. Methods A cross-sectional analytical study. A validated interviewer-administered GORD scale was used to assess frequency and severity of seven GORD symptoms. Subjects were consecutive asthmatics attending medical clinics. Controls were matched subjects without respiratory symptoms. Results The mean (SD) composite GORD symptom score of asthmatics was significantly higher than controls (21.8 (17.2) versus 12.0 (7.6); P < 0.001) as was frequency of each symptom and RARS. Prevalence of GORD symptoms in asthmatics was 59.4% (95% CI, 59.1%-59.6%) versus 28.5% in controls (95% CI, 29.0% - 29.4%). 36% of asthmatics experienced respiratory symptoms in association with both typical and atypical GORD symptoms, compared to 10% of controls (P < 0.001). An asthmatic had a 3.5 times higher risk of experiencing a GORD symptom after adjusting for confounders (OR 3.5; 95% CI 2.5-5.3). Severity of asthma had a strong dose-response relationship with GORD symptoms. Asthma medication use did not significantly influence the presence of GORD symptoms. Conclusions GORD symptoms and RARS were more prevalent in a cohort of Sri Lankan adult asthmatics compared to non-asthmatics. Increased prevalence of RARS is associated with both typical and atypical symptoms of GORD. Asthma disease and its severity, but not asthma medication, appear to influence presence of GORD symptoms.

  13. Association between psychiatric symptoms and erectile dysfunction.

    Corona, Giovanni; Ricca, Valdo; Bandini, Elisa; Mannucci, Edoardo; Petrone, Luisa; Fisher, Alessandra D; Lotti, Francesco; Balercia, Giancarlo; Faravelli, Carlo; Forti, Gianni; Maggi, Mario


    Erectile dysfunction (ED) is often associated with a wide array of psychiatric symptoms, although few studies systematically address their specific association with ED determinants. The aim of this study is to explore the relationship between ED (as assessed by SIEDY Structured Interview, a 13-item tool which identifies and quantifies the contribution of organic, relational, and intrapsychic domains of ED) and different psychopathological symptoms (as assessed by the Middlesex Hospital Questionnaire, a self-reported test for the screening of mental disorders in a nonpsychiatric setting). A consecutive series of 1,388 (mean age 51 +/- 13 years) male patients with ED was studied. Several hormonal and biochemical parameters were investigated, along with SIEDY Interview and the Middlesex Hospital Questionnaire. Psychiatric symptoms resulted differentially associated with SIEDY domains. Depressive and phobic-anxiety symptoms were associated with the relational domain, somatization with the organic one, while free-floating anxiety, obsessive-compulsive, and phobic symptoms were significantly related with higher intrapsychic SIEDY scores. In addition, relevant depressive symptomatology was associated with hypogonadism, the presence of low frequency of intercourse, hypoactive sexual desire (HSD), and conflictual relationships within the couple and the family. Patients with high free-floating anxiety symptoms were younger, and complained of an unsatisfactory work and a conflictual relationship within family. Conversely, subjects with higher phobic anxious symptoms displayed a more robust relational functioning. Similar results were observed in subjects with obsessive-compulsive symptoms, who also reported a lower prevalence of HSD. Finally, subjects with somatization symptoms showed the worst erectile function. The main value of this study is that it alters various clinicians' belief that many psychiatric symptoms can be found among ED patients. Systematic testing of

  14. Phase relations and equilibrium oxygen partial pressures in the iron-titanium-oxygen system at 1373 K; Tetsu-chitan-sansokei no 1373K ni okeru sokankei to heiko sanso bun`atsu

    Inoue, O.; Ito, S.; Azakami, T. [Tohoku University, Sendai (Japan). Faculty of Engineering


    Phase relations and the equilibrium oxygen partial pressures in the Fe-Ti-O ternary system at 1373 K have been studied using a thermogravimetric technique in various atmospheres buffered by a CO-CO2 gas mixture and X-ray diffraction technique. The results indicate that at 1373 K ilmenite (FeTiO3) can be reduced and decomposed to iron and rutile (TiO2). Consequently upgrading ilmenite to a rutile substitute is possible in principle. From the present results, the standard Gibbs energy of the following reactions was calculated to be -184.7, -196.0 kJ{center_dot}mol{sup -1} at 1373 K, respectively. Fe(s)+FeTiO3(s)+1/2O{sub 2}(g)=Fe2TiO4(s), Fe(s)+TiO{sub 2}(s)+1/2O{sub 2}(g)=`FeTiO3`(s). Both the activities of magnetite and ulv6spinel in the Fe2TiO4-Fe3O4 spinel solid solutions coexisting with metallic iron at 1373 K obtained exhibit negative deviations from Raoult`s law. 19 refs., 10 figs., 3 tabs.

  15. Neurological Signs and Symptoms in Fibromyalgia

    Watson, Nathaniel F.; Buchwald, Dedra; Goldberg, Jack; Noonan, Carolyn; Ellenbogen, Richard G.


    Objective To determine the type and frequency of neurological signs and symptoms in individuals with fibromyalgia (FM). Methods Persons with FM (n=166) and pain-free controls (n=66) underwent systematic neurological examination by a neurologist blinded to disease status. Neurological symptoms present over the preceding 3 months were assessed with a standard questionnaire. We used logistic regression to evaluate the association of neurological symptoms and examination findings with FM status. Within the FM group we examined the correlation between self-reported symptoms and physical examination findings. Results Compared to the control group, age and gender adjusted estimates revealed the FM group had significantly more neurological abnormalities in multiple categories including: cranial nerves IX and X (42% vs. 8%), sensory (65% vs. 25%), motor (33% vs. 3%), and gait (28% vs. 7%). Similarly, the FM group endorsed significantly more neurological symptoms than the control group in 27 of 29 categories with the biggest differences observed for photophobia (70% vs. 6%), poor balance (63% vs. 4%), and weakness (58% vs. 2%) and tingling (54% vs. 4%) in the arms and legs. Poor balance, coordination, tingling, weakness in the arms and legs, and numbness in any part of body correlated with appropriate neurological exam findings in the FM group. Conclusions This blinded, controlled study demonstrated neurological physical examination findings in persons with FM. The FM group had more neurological symptoms than controls, with moderate correlation between symptoms and signs. These findings have implications for the medical work-up of patients with FM.

  16. Mediators between bereavement and somatic symptoms

    Konkolÿ Thege Barna


    Full Text Available Abstract Background In our research we examined the frequency of somatic symptoms among bereaved (N = 185 and non-bereaved men and women in a national representative sample (N = 4041 and investigated the possible mediating factors between bereavement status and somatic symptoms. Methods Somatic symptoms were measured by the Patient Health Questionnaire (PHQ-15, anxiety with a four-point anxiety rating scale, and depression with a nine-item shortened version of the Beck Depression Inventory. Results Among the bereaved, somatic symptoms proved to be significantly more frequent in both genders when compared to the non-bereaved, as did anxiety and depression. On the multivariate level, the results show that both anxiety and depression proved to be a mediator between somatic symptoms and bereavement. The effect sizes indicated that for both genders, anxiety was a stronger predictor of somatic symptoms than depression. Conclusions The results of our research indicate that somatic symptoms accompanying bereavement are not direct consequences of this state but they can be traced back to the associated anxiety and depression. These results draw attention to the need to recognize anxiety and depression looming in the background of somatic complaints in bereavement and to the importance of the dissemination of related information.

  17. Effects of quitting cannabis on respiratory symptoms

    Hancox, Robert J.; Shin, Hayden H.; Gray, Andrew R.; Poulton, Richie; Sears, Malcolm R.


    Smoking cannabis is associated with symptoms of bronchitis. Little is known about the persistence of symptoms after stopping cannabis use. We assessed associations between changes in cannabis use and respiratory symptoms in a population-based cohort of 1037 young adults. Participants were asked about cannabis and tobacco use at ages 18, 21, 26, 32 and 38 years. Symptoms of morning cough, sputum production, wheeze, dyspnoea on exertion and asthma diagnoses were ascertained at the same ages. Frequent cannabis use was defined as ≥52 occasions over the previous year. Associations between frequent cannabis use and respiratory symptoms were analysed using generalised estimating equations with adjustments for tobacco smoking, asthma, sex and age. Frequent cannabis use was associated with morning cough (OR 1.97, pcannabis use was associated with reductions in the prevalence of cough, sputum and wheeze to levels similar to nonusers. Frequent cannabis use is associated with symptoms of bronchitis in young adults. Reducing cannabis use often leads to a resolution of these symptoms. PMID:25837035

  18. Coparenting Behaviors as Mediators Between Postpartum Parental Depressive Symptoms and Toddler’s Symptoms

    Hervé Tissot


    Full Text Available Postpartum parental depression, even of mild intensity and short duration, has negative consequences on child development, including increased externalizing and internalizing symptoms. Studies revealed that the links between parental depression and child development are mediated by parenting difficulties. On the other hand, the mediating role of problematic family-level relationships, such as low coparenting support and high conflict between the parents, has rarely been considered, although coparenting difficulties have been linked with both increased depressive symptoms in parents and increased symptoms in toddlers. In the present study, we proposed testing a comprehensive mediation model linking parental depression, coparenting, and child symptoms. At 3 months postpartum, a convenience sample of 69 parental couples completed the Edinburgh Postnatal Depression Scale. In addition, we assessed levels of coparenting support and conflict during a mother–father–infant play situation, the Lausanne Trilogue Play. At 18 months postpartum, both parents assessed child symptoms with the Symptom Checklist Questionnaire. The results showed that coparenting support mediated the links between parental depressive symptoms and child symptoms, but only for mothers: Maternal depressive symptoms were linked with lower coparenting support, which in turn predicted increased psychofunctional symptoms and behavior problems assessed by mothers. Although coparenting conflict behaviors were not predicted by parents’ depressive symptoms, higher conflict was unexpectedly linked with fewer behavior problems assessed by both parents. The present study allowed us to unveil complex pathways between mild parental mood disturbances, family-level relationships, and child development in the first months of the child’s life.

  19. Parent ratings of ADHD symptoms: differential symptom functioning across Malaysian Malay and Chinese children.

    Gomez, Rapson; Vance, Alasdair


    This study examined differential symptom functioning (DSF) in ADHD symptoms across Malay and Chinese children in Malaysia. Malay (N=571) and Chinese (N=254) parents completed the Disruptive Behavior Rating Scale, which lists the DSM-IV ADHD symptoms. DSF was examined using the multiple indicators multiple causes (MIMIC) structural equation modeling procedure. Although DSF was found for a single inattention (IA) symptom and three hyperactivity-impulsivity (HI) symptoms, all these differences had low effect sizes. Controlling for these DSF, Chinese children had higher IA and HI latent factor scores. However the effect sizes were small. Together, these findings suggest adequate support for invariance of the ADHD symptoms across these ethno-cultural groups. The implications of the findings for cross-cultural invariance of the ADHD symptoms are discussed.

  20. Symptoms in smokers trying to quit

    Helgason Asgeir R


    Full Text Available Abstract Aims To describe the prevalence and intensity of different symptoms in relation to tobacco abstinence. To explore latent dimensions between symptoms in smokers trying to quit. Design A cross sectional study using a questionnaire to retrospectively assess symptoms over a period of 12 months. Setting Swedish telephone quitline, a nationwide free of charge service. Participants All 741 individuals who had called the quitline and signed up for smoking cessation treatment between February 2000 to November 2001 and reported to have been smoke free for at least 24 hours during the previous 12 month period from first contact. Measurements Assessments were made by self-report, and abstinence was defined as "not a single puff of smoke during the last week". A factor analysis approach where individual items aggregate into factors was used to explore the relationship between the different symptoms. Findings High intensity of symptoms related to unsuccessful quitting attempts and included craving, irritability, apprehension/anxiety, difficulties concentrating, restlessness, depression/depressed mood, and insomnia. The factor loadings of all 17 symptoms resulted in three factors with factor 1, psychological being the most important. High scores on this factor relates to unsuccessful quitting attempts. Using Nicotine Replacement Therapy (NRT for 5 weeks or longer, reduced symptoms included in factor 1. The other two factors were factor 2 physiological and factor 3 neurological. Conclusion Symptoms that are psychological and/or neurological in nature are interrelated and appear to be the most significant obstacles for successful quitting attempts in a population-based setting. These symptoms may be successfully treated with NRT.

  1. Adolescent attachment, family functioning and depressive symptoms

    Nishola Rawatlal


    Full Text Available Background. Adolescence represents a challenging transitional period where changes in biological, emotional, cognitive and social domains can increase the risk of developing internalised problems including subthreshold depression. Adolescent-parent attachment style, perceived support and family functioning may increase risk for depressive symptoms or may reduce such risk. Adolescent-parent attachment, adolescent-perceived support from parents and family functioning were examined as correlates of depressive symptom presentation within this age group. Methods. Participants included a maternal parent and an adolescent (65.5% female from each family. Adolescents were in Grade 7 (n=175 or Grade 10 (n=31. Data were collected through home interviews. The Self-Report of Family Inventory (SFI, Experiences of Close Relationships Scale (ECR, Network of Relationships Inventory (NRI, Children’s Depression Inventory (CDI and Child Behavior Checklist (CBCL were used to assess depression, parental support and attachment.  Results. Two models were examined: one with adolescent report of depressive symptoms as the outcome and a second with parent report of adolescent internalising symptoms as the outcome. The model predicting adolescent-reported depressive symptoms was significant with older age, higher levels of avoidant attachment, and higher levels of youth-reported dysfunctional family interaction associated with more depressive symptomatology. In the model predicting parent report of adolescent internalising symptoms only higher levels of dysfunctional family interaction, as reported by the parent, were associated with higher levels of internalising symptoms. Conclusion. Positive family communication, cohesion and support predictive of a secure parent-adolescent attachment relationship reduced the risk of a depressive symptom outcome. Secure adolescents were able to regulate their emotions, knowing that they could seek out secure base attachment relations

  2. Somatic symptom disorder treated with electroconvulsive therapy.

    Borisovskaya, Anna; Augsburger, Jay Alan


    Somatic symptom disorder (SSD) is a challenging condition to treat with chronic pain, a common and disabling symptom. We present a patient who received electroconvulsive therapy (ECT) for SSD with significant improvement in pain and gastrointestinal symptoms. We also present a brief literature review of similar cases treated with ECT. Preliminary evidence suggests that ECT should be considered for treatment of SSD comorbid with major depressive disorder, when standard treatments fail. Further research is needed to clarify whether ECT can be used for SSD without associated depression.

  4. Development and validation of an instrument for rapidly assessing symptoms: the general symptom distress scale.

    Badger, Terry A; Segrin, Chris; Meek, Paula


    Symptom assessment has increasingly focused on the evaluation of total symptom distress or burden rather than assessing only individual symptoms. The challenge for clinicians and researchers alike is to assess symptoms, and to determine the symptom distress associated with the symptoms and the patient's ability for symptom management without a lengthy and burdensome assessment process. The objective of this article was to discuss the psychometric evaluation of a brief general symptom distress scale (GSDS) developed to assess specific symptoms and how they rank in relation to each other, the overall symptom distress associated with the symptom schema, and provide an assessment of how well or poorly that symptom schema is managed. Results from a pilot study about the initial development of the GSDS with 76 hospitalized patients are presented, followed by a more complete psychometric evaluation of the GSDS using three samples of cancer patients (n=190) and their social network members, called partners in these studies (n=94). Descriptive statistics were used to describe the GSDS symptoms, symptom distress, and symptom management. Point biserial correlations indexed the associations between dichotomous symptoms and continuous measures, and conditional probabilities were used to illustrate the substantial comorbidities of this sample. Internal consistency was examined using the KR-20 coefficient, and test-retest reliability was examined. Construct validity and predictive validity also were examined. The GSDS demonstrated satisfactory internal consistency and test-retest reliability, and good construct validity and predictive validity. The total score on the GSDS, symptom distress, and symptom management correlated significantly with related constructs of depression, positive and negative affect, and general health. The GSDS was able to demonstrate its ability to distinguish between those with or without chronic illness, and was able to significantly predict scores on

  12. Symptoms predicting psychosocial impairment in bulimia nervosa.

    Jenkins, Paul E; Staniford, Jessica; Luck, Amy


    The current study aimed to determine which particular eating disorder (ED) symptoms and related features, such as BMI and psychological distress, uniquely predict impairment in bulimia nervosa (BN). Two hundred and twenty-two adults with BN completed questionnaires assessing ED symptoms, general psychological distress, and psychosocial impairment. Regression analyses were used to determine predictors which account for variance in impairment. Four variables emerged as significant predictors of psychosocial impairment: concerns with eating; concerns with weight and shape; dietary restraint; and general psychological distress. Findings support previous work highlighting the importance of weight and shape concerns in determining ED-related impairment. Other ED symptoms, notably dietary restraint and concerns with eating, were also significant predictors as was psychological distress. Results suggest that cognitive aspects of EDs, in addition to psychological distress, may be more important determinants of impairment than behavioural symptoms, such as binge eating or purging.

  17. [Treatment of multiple sclerosis symptoms and exacerbations].

    Prieto González, José María


    In the last few years, there has been an explosion of new drugs acting on the clinical course of multiple sclerosis (MS) but less attention has been paid to better knowledge of the symptoms of this disease and their pathogenesis and treatment, which is essential to improve patients' quality of life. Because many patients have numerous concurrent symptoms during their clinical course, their management is complex and consequently it is important to know which symptoms are a direct result of the degenerative lesions of MS. The present article describes all the therapeutic options available for spasticity and its associated pain, paroxystic symptoms, fatigue, genitourinary disorders and sexual dysfunction, tremor, ataxia, gait disorder and cognitive impairment, with special emphasis on novel treatments. The article also defines exacerbations, how to recognize them and the available treatments, mainly oral administration of high-dose methylprednisolone and plasmapheresis.

  3. Sleep disorders as core symptoms of depression.

    Nutt, David; Wilson, Sue; Paterson, Louise


    Links between sleep and depression are strong. About three quarters of depressed patients have insomnia symptoms, and hypersomnia is present in about 40% of young depressed adults and 10% of older patients, with a preponderance in females. The symptoms cause huge distress, have a major impact on quality of life, and are a strong risk factor for suicide. As well as the subjective experience of sleep symptoms, there are well-documented changes in objective sleep architecture in depression. Mechanisms of sleep regulation and how they might be disturbed in depression are discussed. The sleep symptoms are often unresolved by treatment, and confer a greater risk of relapse and recurrence. Epidemiological studies have pointed out that insomnia in nondepressed subjects is a risk factor for later development of depression. There is therefore a need for more successful management of sleep disturbance in depression, in order to improve quality of life in these patients and reduce an important factor in depressive relapse and recurrence.

  4. Depressive symptoms and symptoms of post-traumatic stress disorder in women after childbirth.

    Zaers, Stefanie; Waschke, Melanie; Ehlert, Ulrike


    This study examined the course of psychological problems in women from late pregnancy to six months postpartum, the rates of psychiatric, especially depressive and post-traumatic stress symptoms and possible related antecedent variables. During late pregnancy, one to three days postpartum, six weeks and six months postpartum, 47 of the 60 participating women completed a battery of questionnaires including the General Health Questionnaire, the State-Trait Anxiety Inventory, the Edinburgh Postnatal Depression Scale, and the PTSD Symptom Scale. In general, most women recovered from psychiatric and somatic problems over the period of investigation. However, depressive and post-traumatic stress symptoms in particular were not found to decline significantly. Six weeks postpartum, 22% of the women had depressive symptoms, with this figure remaining at 21.3% six months postpartum. In addition, 6% of the women studied reported clinically significant PTSD symptoms at six weeks postpartum with 14.9% reporting such symptoms at six months postpartum. The most important predictor for depressive and post-traumatic stress symptoms was the block variable "anxiety in late pregnancy". Other predictors were the variables "psychiatric symptoms in late pregnancy", "critical life events" and the "experience of delivery". The results of our study show a high prevalence rate of psychiatric symptoms in women after childbirth and suggest, besides the experience of the delivery itself, a vulnerability or predisposing history that makes the development of psychiatric symptoms after childbirth more probable.

  6. Symptoms of pseudoallergy and histamine metabolism disorders

    Joanna Kacik


    Full Text Available Histamine intolerance is a poorly investigated type of hypersensitivity responsible for a number of often serious symptoms, erroneously interpreted as food allergy. Endogenous histamine originates from the histidine amino acid with the help of the histidine decarboxylase enzyme. Apart from the endogenous production histamine may be supplied to the body with food. Slow-maturing and fermenting products are characterised by particularly high levels of histamine. Some food products stimulate excessive release of histamine from stores in the body as well as containing significant amounts of it. These products include spices, herbs, dried fruits and a large group of food additives. Histamine intolerance is considered to be a condition in which the amount of histamine in the body exceeds its tolerance threshold, which leads to the development of adverse reactions. These reactions primarily include skin symptoms (pruritus, urticaria, skin reddening, acne lesions, angioedema, respiratory symptoms (nasal obstruction and watery discharge, sneezing, coughing, wheezing, gastrointestinal symptoms (abdominal cramps, diarrhoea, bloating, nervous system symptoms (headaches, fatigue, irritability, anxiety, panic attacks, cardiovascular symptoms (tachycardia, hypotension, chest pain, primary dysmenorrhoea and many more. It is estimated that nearly 1% of society is susceptible to histamine intolerance. The diagnosis of this disorder is based on observing at least two characteristic symptoms and their disappearance or improvement following histamine-free diet. A new, although not easily accessible diagnostic tool is assay for serum diamine oxidase activity, which correlates to a significant extent with symptoms of histamine intolerance. Normal activity of diamine oxidase is considered to be the amount of >80 HDU/mL, decreased activity – 40–80 HDU/mL and severely decreased activity – <40 HDU/mL. Currently the option of diamine oxidase supplementation is

  8. Parkinson's disease and narcolepsy-like symptoms.

    Ylikoski, Ari; Martikainen, Kirsti; Sarkanen, Tomi; Partinen, Markku


    Various sleep-related problems, for example, insomnia and symptoms of rapid eye movement behavior disorder (RBD), are common in patients with Parkinson's disease (PD). We studied the prevalence of symptoms of narcolepsy (NARC), hallucinations, and RBD and their association with other symptoms. Altogether, 1447 randomly selected patients with PD, aged 43-89 years, participated in a questionnaire study. A structured questionnaire with 207 items was based on the Basic Nordic Sleep Questionnaire. Questions on demographics, PD, RBD, and other issues were included. The response rate was 59.0%; of these patients, 73% had answered to all questions that were used in the analyses (N = 623). The occurrence of suspected narcolepsy (Ullanlinna Narcolepsy Scale ≥ 14 and Epworth Sleepiness Scale ≥ 11) was observed in 9.3% of the subjects (PD with NARC), RBD (REM Sleep Behavior Disorder Screening Questionnaire ≥ 6) in 39.2% of all patients with PD, and in 62.1% of those with PD and NARC. In patients with PD, hallucinations before going to bed in the evening occurred in 5.8%, hypnagogic hallucinations in 4.0%, hallucinations during night 8.3%, and hypnopompic hallucinations in 3.2%. Cataplexy symptoms occurred in 43.1% of subjects with PD and NARC. In a logistic regression analysis, PD with NARC was associated with RBD, all types of hallucinations, daytime sleepiness, fatigue, insomnia, and intense dreaming also when adjusted for age, sex, disease duration, and levodopa. Narcolepsy-like symptoms may be present in patients with PD. Symptoms of RBD were associated with symptoms of narcolepsy including symptoms of cataplexy. Copyright © 2014 Elsevier B.V.

  9. Cannabis use and adult ADHD symptoms.

    Fergusson, David M; Boden, Joseph M


    The present study examined the associations between cannabis use in adolescence and young adulthood and self-reported adult attention deficit/hyperactivity disorder (ADHD) symptoms in adulthood. A 25-year prospective longitudinal study of the health, development, and adjustment of a birth cohort of 1265 New Zealand children. Measures included assessments of adolescent and young adult cannabis use and ADHD symptoms at age 25, measures of childhood socioeconomic disadvantage, family adversity, childhood and early adolescent behavioural adjustment and cognitive ability, and adolescent and young adult other drug use. Cannabis use by age 25 was significantly (pADHD symptoms at age 25. Adjustment of the association for potentially confounding factors from childhood and early adolescence reduced the magnitude of the association, but it remained statistically significant (pcannabis use and adult ADHD symptoms to statistical non-significance (p>.20). The current study suggested that the association between cannabis use and adult ADHD symptoms was mediated by other substance use that was associated with cannabis use. The results suggest that cannabis use leads to other drug use, which in turn leads to increased ADHD symptoms. However, it should be noted that the potential influence of such factors as genetic predispositions may still be unaccounted for.

  10. Progression of motor symptoms in Parkinson's disease

    Ruiping Xia; Zhi-Hong Mao


    Parkinson's disease (PD) is a chronic progressive neurodegenerative disease that is clinically manifested by a triad of cardinal motor symptoms - rigidity,bradykinesia and tremor - due to loss of dopaminergic neurons.The motor symptoms of PD become progressively worse as the disease advances.PD is also a heterogeneous disease since rigidity and bradykinesia are the major complaints in some patients whereas tremor is predominant in others.In recent years,many studies have investigated the progression of the hallmark symptoms over time,and the cardinal motor symptoms have different rates of progression,with the disease usually progressing faster in patients with rigidity and bradykinesia than in those with predominant tremor.The current treatment regime of dopamine-replacement therapy improves motor symptoms and alleviates disability.Increasing the dosage of dopaminergic medication is commonly used to combat the worsenirtg symptoms.However,the drug-induced involuntary body movements and motor comphcations can significantly contribute to overall disability.Further,none of the currently-available therapies can slow or halt the disease progression.Significant research efforts have been directed towards developing neuroprotective or disease-modifying agents that are intended to slow the progression.In this article,the most recent clinical studies investigating disease progression and current progress on the development of disease-modifying drug trials are reviewed.

  12. Depicting Changes in Multiple Symptoms Over Time.

    Muehrer, Rebecca J; Brown, Roger L; Lanuza, Dorothy M


    Ridit analysis, an acronym for Relative to an Identified Distribution, is a method for assessing change in ordinal data and can be used to show how individual symptoms change or remain the same over time. The purposes of this article are to (a) describe how to use ridit analysis to assess change in a symptom measure using data from a longitudinal study, (b) give a step-by-step example of ridit analysis, (c) show the clinical relevance of applying ridit analysis, and (d) display results in an innovative graphic. Mean ridit effect sizes were calculated for the frequency and distress of 64 symptoms in lung transplant patients before and after transplant. Results were displayed in a bubble graph. Ridit analysis allowed us to maintain the specificity of individual symptoms and to show how each symptom changed or remained the same over time. The bubble graph provides an efficient way for clinicians to identify changes in symptom frequency and distress over time. © The Author(s) 2014.

  13. Depressive Symptoms, Emotion Dysregulation, and Bulimic Symptoms in Youth With Type 1 Diabetes

    Young-Hyman, Deborah L.; Peterson, Claire M.; Fischer, Sarah; Markowitz, Jessica T.; Muir, Andrew B.; Laffel, Lori M.


    This study evaluated the associations between depressive symptoms, emotion dysregulation and bulimic symptoms in youth with type 1 diabetes (T1D) in the context of the diagnosis and treatment of T1D. Study participants were 103 youth in 2 distinct groups: newly diagnosed (New) or transitioning to pump therapy (continuous subcutaneous insulin infusion [CSII]; “Pump”), who completed questionnaires regarding symptoms of depression, emotion dysregulation, and bulimia. Glycemic control (A1c), height, weight, and questionnaires were evaluated within 10 days of diagnosis (n = 58) or at education/clinic visit before starting insulin utilizing CSII (n = 45). In the newly diagnosed group, only depression accounted for significant variance in bulimia scores (β = .47, P symptoms and emotion dysregulation were associated with greater bulimic symptoms. Depressive symptoms and emotion dysregulation, an indicator of poor coping/behavioral control, could help explain adoption of disordered eating behaviors in youth with T1D who are transitioning to pump therapy.

  15. A Structural Equation Model of HIV-related Symptoms, Depressive Symptoms, and Medication Adherence

    Yoo-Jeong, Moka; Waldrop-Valverde, Drenna; McCoy, Katryna; Ownby, Raymond L


    Adherence to combined antiretroviral therapy (cART) remains critical in management of HIV infection. This study evaluated depression as a potential mechanism by which HIV-related symptoms affect medication adherence and explored if particular clusters of HIV symptoms are susceptible to this mechanism. Baseline data from a multi-visit intervention study were analyzed among 124 persons living with HIV (PLWH). A bifactor model showed two clusters of HIV-related symptom distress: general HIV-rela...

  16. A randomized controlled trial of an HIV/AIDS Symptom Management Manual for depressive symptoms.

    Eller, Lucille S; Kirksey, Kenn M; Nicholas, Patrice K; Corless, Inge B; Holzemer, William L; Wantland, Dean J; Willard, Suzanne S; Robinson, Linda; Hamilton, Mary Jane; Sefcik, Elizabeth F; Moezzi, Shahnaz; Mendez, Marta Rivero; Rosa, Maria; Human, Sarie


    Abstract Depressive symptoms are highly prevalent, underdiagnosed, and undertreated in people living with HIV/AIDS (PLWH), and are associated with poorer health outcomes. This randomized controlled trial examined the effects of the HIV/AIDS Symptom Management Manual self-care symptom management strategies compared with a nutrition manual on depressive symptoms in an international sample of PLWH. The sample consisted of a sub-group (N=222) of participants in a larger study symptom management study who reported depressive symptoms. Depressive symptoms of the intervention (n=124) and control (n=98) groups were compared over three months: baseline, one-month, and two-months. Use and effectiveness of specific strategies were examined. Depressive symptom frequency at baseline varied significantly by country (χ (2) 12.9; p=0.04). Within the intervention group there were significant differences across time in depressive symptom frequency [F(2, 207) = 3.27, p=0.05], intensity [F(2, 91) = 4.6, p=0.01], and impact [F(2, 252) = 2.92, p= 0.05), and these were significantly lower at one month but not at two months, suggesting that self-care strategies are effective in reducing depressive symptoms, however effects may be short term. Most used and most effective self-care strategies were distraction techniques and prayer. This study suggests that people living with HIV can be taught and will employ self-care strategies for management of depressive symptoms and that these strategies are effective in reducing these symptoms. Self-care strategies are noninvasive, have no side-effects, and can be readily taught as an adjunct to other forms of treatment. Studies are needed to identify the most effective self-care strategies and quantify optimum dose and frequency of use as a basis for evidence-based practice.

  17. Prevalence of gastro-oesophageal reflux disease symptoms and reflux-associated respiratory symptoms in asthma

    de Silva H Janaka


    Full Text Available Abstract Background Gastro-oesophageal reflux disease (GORD symptoms are common in asthma and have been extensively studied, but less so in the Asian continent. Reflux-associated respiratory symptoms (RARS have, in contrast, been little-studied globally. We report the prevalence of GORD symptoms and RARS in adult asthmatics, and their association with asthma severity and medication use. Methods A cross-sectional analytical study. A validated interviewer-administered GORD scale was used to assess frequency and severity of seven GORD symptoms. Subjects were consecutive asthmatics attending medical clinics. Controls were matched subjects without respiratory symptoms. Results The mean (SD composite GORD symptom score of asthmatics was significantly higher than controls (21.8 (17.2 versus 12.0 (7.6; P P Conclusions GORD symptoms and RARS were more prevalent in a cohort of Sri Lankan adult asthmatics compared to non-asthmatics. Increased prevalence of RARS is associated with both typical and atypical symptoms of GORD. Asthma disease and its severity, but not asthma medication, appear to influence presence of GORD symptoms.

  18. Validation of a self-reported HIV symptoms list: the ISS-HIV symptoms scale.

    Bucciardini, Raffaella; Pugliese, Katherina; Francisci, Daniela; Costantini, Andrea; Schiaroli, Elisabetta; Cognigni, Miriam; Tontini, Chiara; Lucattini, Stefano; Fucili, Luca; Di Gregorio, Massimiliano; Mirra, Marco; Fragola, Vincenzo; Pompili, Sara; Murri, Rita; Vella, Stefano


    To describe the development and the psychometric properties of the Istituto Superiore di Sanità-HIV symptoms scale (lSS-HIV symptoms scale). The ISS-HIV symptom scale was developed by an Italian working team including researchers, physicians and people living with HIV. The development process went through the following steps: (1) review of HIV/AIDS literature; (2) focus group; (3) pre-test analysis; (4) scale validation. The 22 symptoms of HIV-ISS symptoms scale were clustered in five factors: pain/general discomfort (7 items); depression/anxiety (4 items); emotional reaction/psychological distress (5 items); gastrointestinal discomfort (4 items); sexual discomfort (2 items). The internal consistence reliability was for all factors within the minimum accepted standard of 0.70. The results of this study provide a preliminary evidence of the reliability and validity of the ISS-HIV symptoms scale. In the new era where HIV infection has been transformed into a chronic diseases and patients are experiencing a complex range of symptoms, the ISS-HIV symptoms scale may represent an useful tool for a comprehensive symptom assessment with the advantage of being easy to fill out by patients and potentially attractive to physicians mainly because it is easy to understand and requires short time to interpret the results.

  1. Sexual Orientation and Depressive Symptoms in Adolescents.

    Luk, Jeremy W; Gilman, Stephen E; Haynie, Denise L; Simons-Morton, Bruce G


    Sexual orientation disparities in adolescent depressive symptoms are well established, but reasons for these disparities are less well understood. We modeled sexual orientation disparities in depressive symptoms from late adolescence into young adulthood and evaluated family satisfaction, peer support, cyberbullying victimization, and unmet medical needs as potential mediators. Data were from waves 2 to 6 of the NEXT Generation Health Study ( n = 2396), a population-based cohort of US adolescents. We used latent growth models to examine sexual orientation disparities in depressive symptoms in participants aged 17 to 21 years, conduct mediation analyses, and examine sex differences. Relative to heterosexual adolescents, sexual minority adolescents (those who are attracted to the same or both sexes or are questioning; 6.3% of the weighted sample) consistently reported higher depressive symptoms from 11th grade to 3 years after high school. Mediation analyses indicated that sexual minority adolescents reported lower family satisfaction, greater cyberbullying victimization, and increased likelihood of unmet medical needs, all of which were associated with higher depressive symptoms. The mediating role of cyberbullying victimization was more pronounced among male than female participants. Sexual minority adolescents reported higher depressive symptoms than heterosexual adolescents from late adolescence into young adulthood. Collectively, low family satisfaction, cyberbullying victimization, and unmet medical needs accounted for >45% of differences by sexual orientation. Future clinical research is needed to determine if interventions targeting these psychosocial and health care-related factors would reduce sexual orientation disparities in depressive symptoms and the optimal timing of such interventions.

  2. Recognition of depressive symptoms by physicians

    Sergio Gonçalves Henriques


    Full Text Available OBJECTIVE: To investigate the recognition of depressive symptoms of major depressive disorder (MDD by general practitioners. INTRODUCTION: MDD is underdiagnosed in medical settings, possibly because of difficulties in the recognition of specific depressive symptoms. METHODS: A cross-sectional study of 316 outpatients at their first visit to a teaching general hospital. We evaluated the performance of 19 general practitioners using Primary Care Evaluation of Mental Disorders (PRIME-MD to detect depressive symptoms and compared them to 11 psychiatrists using Structured Clinical Interview Axis I Disorders, Patient Version (SCID I/P. We measured likelihood ratios, sensitivity, specificity, and false positive and false negative frequencies. RESULTS: The lowest positive likelihood ratios were for psychomotor agitation/retardation (1.6 and fatigue (1.7, mostly because of a high rate of false positive results. The highest positive likelihood ratio was found for thoughts of suicide (8.5. The lowest sensitivity, 61.8%, was found for impaired concentration. The sensitivity for worthlessness or guilt in patients with medical illness was 67.2% (95% CI, 57.4-76.9%, which is significantly lower than that found in patients without medical illness, 91.3% (95% CI, 83.2-99.4%. DISCUSSION: Less adequately identified depressive symptoms were both psychological and somatic in nature. The presence of a medical illness may decrease the sensitivity of recognizing specific depressive symptoms. CONCLUSIONS: Programs for training physicians in the use of diagnostic tools should consider their performance in recognizing specific depressive symptoms. Such procedures could allow for the development of specific training to aid in the detection of the most misrecognized depressive symptoms.

  3. No sweat: managing menopausal symptoms at work.

    Hickey, Martha; Riach, Kathleen; Kachouie, Reza; Jack, Gavin


    Menopause usually occurs between the ages of 45 and 55, a time when women are likely to be in the paid workforce. Most women have menopausal symptoms and these may impact on daytime function and work performance. This study examines the relationship between reproductive stage, menopausal symptoms and work, and advises how employers can best support menopausal women. An online and paper-based survey was completed in 2015-16 by 1092 women (22% response rate) aged 40 years plus employed in three hospitals in metropolitan Australia. Survey questions examined demographics, health and lifestyle variables, menopausal symptom reporting, and work-related variables. Reproductive stage was determined using modified STRAW +10 principal and descriptive criteria. Reproductive stage was not significantly associated with work engagement, organizational commitment, job satisfaction, work limitations and perceived supervisor support. Postmenopausal women had lower intention to leave their organizations than pre- and peri-menopausal women. While sleep problems were the most commonly reported menopausal symptom by peri-menopausal women, for postmenopausal women it was joint and muscular discomfort. Only hot flushes and vaginal dryness were significantly more frequent in peri- and post, compared to pre-menopausal women. In general, women rated their work performance as high and did not feel that menopausal symptoms impaired their work ability. Most women would appreciate greater organizational support, specifically temperature control, flexible work hours and information about menopause for employees and managers. Most women did not believe that menopausal symptoms negatively impacted on their work. Organizational changes may reduce the burden of menopausal symptoms in the workplace.

  4. Neurologic signs and symptoms in fibromyalgia.

    Watson, Nathaniel F; Buchwald, Dedra; Goldberg, Jack; Noonan, Carolyn; Ellenbogen, Richard G


    To determine the type and frequency of neurologic signs and symptoms in individuals with fibromyalgia (FM). Persons with FM (n = 166) and pain-free controls (n = 66) underwent systematic neurologic examination by a neurologist blinded to disease status. Neurologic symptoms lasting at least 3 months were assessed with a standard questionnaire. We used logistic regression to evaluate the association of neurologic symptoms and examination findings with FM status. Within the FM group we examined the correlation between self-reported symptoms and physical examination findings. Age- and sex-adjusted estimates revealed that compared with the control group, the FM group had significantly more neurologic abnormalities in multiple categories, including greater dysfunction in cranial nerves IX and X (42% versus 8%) and more sensory (65% versus 25%), motor (33% versus 3%), and gait (28% versus 7%) abnormalities. Similarly, the FM group had significantly more neurologic symptoms than the control group in 27 of 29 categories, with the greatest differences observed for photophobia (70% versus 6%), poor balance (63% versus 4%), and weakness (58% versus 2%) and tingling (54% versus 4%) in the arms or legs. Poor balance or coordination, tingling or weakness in the arms or legs, and numbness in any part of the body correlated with appropriate neurologic examination findings in the FM group. This blinded, controlled study demonstrated neurologic physical examination findings in persons with FM. The FM group had more neurologic symptoms than did the controls, with moderate correlation between symptoms and signs. These findings have implications for the medical evaluation of patients with FM.

  5. Gender differences in symptoms of myocardial ischaemia.

    Mackay, Martha H; Ratner, Pamela A; Johnson, Joy L; Humphries, Karin H; Buller, Christopher E


    Better understanding of symptoms of myocardial ischaemia is needed to improve timeliness of treatment for acute coronary syndromes (ACS). Although researchers have suggested sex differences exist in ischaemic symptoms, methodological issues prevent conclusions. Using percutaneous coronary intervention (PCI) balloon inflation as a model of myocardial ischaemia, we explored sex differences in reported symptoms of ischaemia. Patients having non-emergent PCI, but not haemodynamic instability or left bundle branch block or non-acute coronary occlusion, were prospectively recruited. Pre-procedure, descriptions of pre-existing symptoms were obtained using open-ended questioning. Inflation was maintained for 2 min or until moderate discomfort or clinical instability occurred. During inflation, subjects were exhaustively questioned about their symptoms. Concurrent ECG data were collected. The final sample was 305 [39.7% women; mean age 63.9 (± 10.6)]. No sex differences were found in rates of chest or typical ischaemic discomfort, regardless of ischaemic status. Women were significantly more likely to report throat/jaw discomfort [odds ratio: 2.91; 95% confidence interval: 1.58-5.37] even after statistical adjustment for clinical and demographic variables. This prospective study with ECG-affirmed ischaemia found no statistically significant differences in women's and men's rates of chest and other typical symptoms during ischaemia, although women were more likely to experience throat and jaw discomfort. Currently both popular press and some patient education materials suggest women experience myocardial ischaemia differently from men. Steps to ensure women and health professionals are alert for the classic symptoms of myocardial ischaemia in women, as well as men, may be warranted.

    Pringuey, D; Paquin, N; Cherikh, F; Giordana, B; Belzeaux, R; Cermolacce, M; Adida, M; Azorin, J-M


    The history of negative symptoms of schizophrenia rises early days of medicine in clinical and pathophysiological differences between positive and negative and their complex joint. Forming a set of typical core of symptoms, and some feature of a syndrome belonging to a specific pathophysiological mechanism, negative symptoms of schizophrenia emerge from old descriptions of clinical pictures, related to the overall look of madness, the heart of alienation, a central sign of early dementia, gradually more precisely describing the strange nature of the autistic withdrawal and schizophrenic apragmatism. At therapeutic era, negative symptoms have taken over the positive symptoms to establish an operational criteria whose importance lies in the progressive severity of this clinical type and in their contribution to therapeutic resistance. Despite the efforts of modern typological classifications, this work rehabilitates the old concept of "unitary psychosis" by defining a common symptomatic core to multiple clinical forms of psychosis, combining deficit of emotional expression and avolition, meaning a native psychopathology and a pathophysiology possibly in a common final way, and calling the arrival of new treatment strategies.

On one hand, behavioral symptoms in patients with mild cognitive impairment (MCI can indicate an increased risk of progressing to dementia. On the other hand, mild behavioral impairment (MBI in patients who usually have normal cognition indicates an increased risk of developing dementia. Whatever the cause, all dementias carry a high rate of NPI. These symptoms can be observed at any stage of the disease, may fluctuate over its course, are a leading cause of stress and overload for caregivers, and increase rates of hospitalization and early institutionalization for patients with dementia. The clinician should be able to promptly recognize NPI through the use of instruments capable of measuring their frequency and severity to support diagnosis, and to help monitor the treatment of behavioral symptoms. The aims of this review are to describe and update the construct ‘MBI’ and to revise the reported NPS related to prodromal stages of dementia (MCI and MBI and dementia stages of Alzheimer’s disease and frontotemporal lobar degeneration.

  9. [Ophthalmological symptoms of measles and their treatment].

    Végh, Mihály; Hári-Kovács, András; Roth, Hans-Walter; Facskó, Andrea


    Measles, caused by the Morbilli virus, is a highly (about 95 %) contagious disease affecting primarily children, but without proper immunisation, adults can also be infected. The leading symptoms of the disease are high fever that presents after an incubation period of 9-10 days and the red rash that begins several days after the fever starts. Beyond specific generalized symptoms, measles may have ocular symptoms. The most commonly occurring conjunctivitis, the so-called "red eye symptom", is not characteristic only for measles infection, however, by taking the generalized symptoms it can suggest the diagnosis at the beginning of the disease. Conjunctivitis of varying severity is noticed in the half of the cases without using ophthalmological instrumentation. Using ophthalmological instrumentation, the mild forms of conjunctivitis can be diagnosed, by meticulous ophthalmological examination, further eye diseases can be discovered. The viral conjunctivitis can progress to keratitis and bacterial superinfection can occur. If the infection presents in childhood it can affect the posterior segment. The fight against measles is very effective in Hungary since the vaccination has been introduced, and the lack of vaccination is also the primary cause of the risk to the disease. In the diagnosis, symptomatic treatment of the disease and the curbing of possible mass infections, the practicing physician (general practitioner) has a key role. The correct care of the infected patient in Hungary is provided by a methodological letter, professional information and legal guides. Orv Hetil. 2017; 158(39): 1523-1527.

  10. Maternal depressive symptoms, employment, and social support.

    Gjerdingen, Dwenda; McGovern, Patricia; Attanasio, Laura; Johnson, Pamela Jo; Kozhimannil, Katy Backes


    The purpose of this study was to characterize the relationship between maternal depressive symptoms and employment and whether it is mediated by social support. We used data from a nationally representative sample of 700 US women who gave birth in 2005 and completed 2 surveys in the Listening to Mothers series, the first in early 2006, an average of 7.3 months postpartum, and the second an average of 13.4 months postpartum. A dichotomous measure of depressive symptoms was calculated from the 2-item Patient Health Questionnaire, and women reported their employment status and levels of social support from partners and others. We modeled the association between maternal employment and depressive symptoms using multivariate logistic regression, including social support and other control variables. Maternal employment and high support from a nonpartner source were both independently associated with significantly lower odds of depressive symptoms (adjusted odds ratio [AOR], 0.35 and P = .011, and AOR, 0.40, P = .011, respectively). These relationships remained significant after controlling for mothers' baseline mental and physical health, babies' health, and demographic characteristics (AOR, 0.326 and P = .015, and AOR, 0.267 and P = .025, respectively). Maternal employment and strong social support, particularly nonpartner support, were independently associated with fewer depressive symptoms. Clinicians should encourage mothers of young children who are at risk for depression to consider ways to optimize their employment circumstances and "other" social support.

  11. External eye symptoms in indoor environments.

    Wolkoff, P


    Eye irritation, for example dry or irritated eyes, is generally among top three reported symptoms in office-like environments, in particular among workplaces with cognitive demanding visual display unit (VDU) work. The symptoms are especially among middle and advanced ages and particularly among women more than men. The symptoms are also among the most commonly reported complaints in the eye clinic. To be in a position to interpret the high prevalence of eye symptoms, a multidisciplinary and integrated approach is necessary that involves the external eye physiology (separate from internal eye effects), eye diseases (evaporative dry eye (DE), aqueous-deficient DE, and gland dysfunctions), and risk factors that aggravate the stability of precorneal tear film (PTF) resulting in hyperosmolarity and initiation of inflammatory reactions. Indoor environmental, occupational and personal risk factors may aggravate the PTF stability; factors such as age, contact lenses, cosmetics, diet, draft, gender, low humidity and high temperature, medication, outdoor and combustion pollutants, and VDU work. Psychological stressors may further influence the reporting behavior of eye symptoms. The impact of the risk factors may occur in a combined and exacerbating manner. © 2016 The Authors.

  12. Naturalistically observed conflict and youth asthma symptoms.

    Tobin, Erin T; Kane, Heidi S; Saleh, Daniel J; Naar-King, Sylvie; Poowuttikul, Pavadee; Secord, Elizabeth; Pierantoni, Wayne; Simon, Valerie A; Slatcher, Richard B


    To investigate the links between naturalistically observed conflict, self-reported caregiver-youth conflict, and youth asthma symptoms. Fifty-four youth with asthma (age range: 10-17 years) wore the Electronically Activated Recorder (EAR) for a 4-day period to assess interpersonal conflict and caregiver-youth conflict as they occur in daily life. Conflict also was assessed with baseline self-report questionnaires and daily diaries completed by youth participants and their caregivers. Asthma symptoms were assessed using daily diaries, baseline self-reports, and wheezing, as coded from the EAR. EAR-observed measures of conflict were strongly associated with self-reported asthma symptoms (both baseline and daily diaries) and wheezing coded from the EAR. Further, when entered together in regression analyses, youth daily reports of negative caregiver-youth interactions and EAR-observed conflict uniquely predicted asthma symptoms; only EAR-observed conflict was associated with EAR-observed wheezing. These findings demonstrate the potential impact of daily conflict on youth asthma symptoms and the importance of assessing conflict as it occurs in everyday life. More broadly, they point to the importance of formulating a clear picture of family interactions outside of the lab, which is essential for understanding how family relationships "get under the skin" to affect youth health.

  13. Symptom overlap in anxiety and multiple sclerosis.

    O Donnchadha, Seán


    BACKGROUND: The validity of self-rated anxiety inventories in people with multiple sclerosis (pwMS) is unclear. However, the appropriateness of self-reported depression scales has been widely examined. Given somatic symptom overlap between depression and MS, research emphasises caution when using such scales. OBJECTIVE: This study evaluates symptom overlap between anxiety and MS in a group of 33 individuals with MS, using the Beck Anxiety Inventory (BAI). METHODS: Participants underwent a neurological examination and completed the BAI. RESULTS: A novel procedure using hierarchical cluster analysis revealed three distinct symptom clusters. Cluster one (\\'wobbliness\\' and \\'unsteady\\') grouped separately from all other BAI items. These symptoms are well-recognised MS-related symptoms and we question whether their endorsement in pwMS can be considered to reflect anxiety. A modified 19-item BAI (mBAI) was created which excludes cluster one items. This removal reduced the number of MS participants considered \\'anxious\\' by 21.21% (low threshold) and altered the level of anxiety severity for a further 27.27%. CONCLUSION: Based on these data, it is suggested that, as with depression measures, researchers and clinicians should exercise caution when using brief screening measures for anxiety in pwMS.

  14. Depressive symptoms in institutionalized older adults

    Lívia Maria Santiago


    Full Text Available OBJECTIVE To estimate the prevalence of depressive symptoms among institutionalized elderly individuals and to analyze factors associated with this condition. METHODS This was a cross-sectional study involving 462 individuals aged 60 or older, residents in long stay institutions in four Brazilian municipalities. The dependent variable was assessed using the 15-item Geriatric Depression Scale. Poisson’s regression was used to evaluate associations with co-variables. We investigated which variables were most relevant in terms of presence of depressive symptoms within the studied context through factor analysis. RESULTS Prevalence of depressive symptoms was 48.7%. The variables associated with depressive symptoms were: regular/bad/very bad self-rated health; comorbidities; hospitalizations; and lack of friends in the institution. Five components accounted for 49.2% of total variance of the sample: functioning, social support, sensory deficiency, institutionalization and health conditions. In the factor analysis, functionality and social support were the components which explained a large part of observed variance. CONCLUSIONS A high prevalence of depressive symptoms, with significant variation in distribution, was observed. Such results emphasize the importance of health conditions and functioning for institutionalized older individuals developing depression. They also point to the importance of providing opportunities for interaction among institutionalized individuals.

  15. Adverse mood symptoms with oral contraceptives.

    Poromaa, Inger Sundström; Segebladh, Birgitta


    In spite of combined oral contraceptives (COCs) having been available for more than 50 years, surprisingly little is known about the prevalence of truly COC-related adverse mood symptoms and about the underlying biological mechanisms of proposed changes in mood and affect. Precise estimates of COC-related adverse mood symptoms are not available due to the lack of placebo-controlled trials. In prospective trials the frequency of women who report deteriorated mood or deteriorated emotional well-being varies between 4 and 10%, but it can be assumed that the causal relation in these prevalence rates is overestimated. Adverse mood symptoms and somatic symptoms are most pronounced during the pill-free interval of the treatment cycles, but whether extended COC regimens would be more favorable in this respect is not known. COCs with anti-androgenic progestagens, such as drospirenone and desogestrel, appear more favorable in terms of mood symptoms than progestagens with a more androgenic profile. Available data suggest that lower doses of ethinylestradiol could be beneficial. © 2012 The Authors Acta Obstetricia et Gynecologica Scandinavica© 2012 Nordic Federation of Societies of Obstetrics and Gynecology.

  16. Coexisting anxiety and depressive symptoms in patients with heart failure.

    Dekker, Rebecca L; Lennie, Terry A; Doering, Lynn V; Chung, Misook L; Wu, Jia-Rong; Moser, Debra K


    Among patients with heart failure (HF), anxiety symptoms may co-exist with depressive symptoms. However, the extent of overlap and risk factors for anxiety symptoms have not been thoroughly described. The aim of this study was to describe the coexistence of anxiety and depressive symptoms, and to determine the predictors of anxiety symptoms in patients with HF. The sample consisted of 556 outpatients with HF (34% female, 62±12 years, 54% New York Heart Association (NYHA) class III/IV) enrolled in a multicenter HF quality of life registry. Anxiety symptoms were assessed with the Brief Symptom Inventory-anxiety subscale. Depressive symptoms were measured with the Beck Depression Inventory-II (BDI). We used a cut-point of 0.35 to categorize patients as having anxiety symptoms or no anxiety symptoms. Logistic regression was used to determine whether age, gender, minority status, educational level, functional status, comorbidities, depressive symptoms, and antidepressant use were predictors of anxiety symptoms. One-third of patients had both depressive and anxiety symptoms. There was a dose-response relationship between depressive symptoms and anxiety symptoms; higher levels of depressive symptoms were associated with a higher level of anxiety symptoms. Younger age (odds ratio (OR)= 0.97, p=0.004, 95% confidence interval (CI) 0.95-0.99) and depressive symptoms (OR =1.25, panxiety symptoms. Patients with HF and depressive symptoms are at high risk for experiencing anxiety symptoms. Clinicians should assess these patients for comorbid anxiety symptoms. Research is needed to test interventions for both depressive and anxiety symptoms.

    Symptoms guide disease management, and patients frequently report HIV-related symptoms, but HIV symptom patterns reported by patients have not been described in the era of improved antiretroviral treatment. The objectives of our study were to investigate the prevalence and burden of symptoms in people living with HIV and attending an outpatient clinic. The prevalence, burden, and bothersomeness of symptoms reported by patients in routine clinic visits during 2011 were assessed using the 20-item HIV Symptom Index. Principal component analysis was used to identify symptom clusters and relationships between groups using appropriate statistic techniques. Two main clusters were identified. The most prevalent and bothersome symptoms were muscle aches/joint pain, fatigue, and poor sleep. A third of patients had seven or more symptoms, including the most burdensome symptoms. Even with improved antiretroviral drug side-effect profiles, symptom prevalence and burden, independent of HIV viral load and CD4+ T cell count, are high. PMID:26790340

  18. Development of symptoms-oriented operating procedures

    Colquhoun, R.


    Until recently, the formal treatment of control room procedures for upset conditions in nuclear power plants has been event-oriented. This orientation was not so much a reflection of power plant operating practice as it was a reflection of design-oriented thinking - design-basis events, therefore event-oriented procedures. Event orientation is not common in other professions. In the medical profession, for example, the stabilization of vital functions through a symptoms-oriented approach has priority over diagnosis and prognosis. The American nuclear power industry has initiated programs for the development and application of a symptoms-oriented approach for handling upset conditions. Canadian programs have independently paralleled the US programs. This article describes the rationale and current applications of the Canadian programs and identifies the relevance of a generic symptoms-based emergency procedure to current operating practices

  19. Lay Consultations in Heart Failure Symptom Evaluation.

    Reeder, Katherine M; Sims, Jessica L; Ercole, Patrick M; Shetty, Shivan S; Wallendorf, Michael


    Lay consultations can facilitate or impede healthcare. However, little is known about how lay consultations for symptom evaluation affect treatment decision-making. The purpose of this study was to explore the role of lay consultations in symptom evaluation prior to hospitalization among patients with heart failure. Semi-structured interviews were conducted with 60 patients hospitalized for acute decompensated heart failure. Chi-square and Fisher's exact tests, along with logistic regression were used to characterize lay consultations in this sample. A large proportion of patients engaged in lay consultations for symptom evaluation and decision-making before hospitalization. Lay consultants provided attributions and advice and helped make the decision to seek medical care. Men consulted more often with their spouse than women, while women more often consulted with adult children. Findings have implications for optimizing heart failure self-management interventions, improving outcomes, and reducing hospital readmissions.

  20. Esophageal stasis in achalasia patients without symptoms after treatment does not predict symptom recurrence

    van Hoeij, F. B.; Smout, A. J. P. M.; Bredenoord, A. J.


    BackgroundAfter achalasia treatment, a subset of patients has poor esophageal emptying without having symptoms. There is no consensus on whether to pre-emptively treat these patients. We hypothesized that, if left untreated, these patients will experience earlier symptom recurrence than patients

  2. SymptomCare@Home: Developing an Integrated Symptom Monitoring and Management System for Outpatients Receiving Chemotherapy.

    Beck, Susan L; Eaton, Linda H; Echeverria, Christina; Mooney, Kathi H


    SymptomCare@Home, an integrated symptom monitoring and management system, was designed as part of randomized clinical trials to help patients with cancer who receive chemotherapy in ambulatory clinics and often experience significant symptoms at home. An iterative design process was informed by chronic disease management theory and features of assessment and clinical decision support systems used in other diseases. Key stakeholders participated in the design process: nurse scientists, clinical experts, bioinformatics experts, and computer programmers. Especially important was input from end users, patients, and nurse practitioners participating in a series of studies testing the system. The system includes both a patient and clinician interface and fully integrates two electronic subsystems: a telephone computer-linked interactive voice response system and a Web-based Decision Support-Symptom Management System. Key features include (1) daily symptom monitoring, (2) self-management coaching, (3) alerting, and (4) nurse practitioner follow-up. The nurse practitioner is distinctively positioned to provide assessment, education, support, and pharmacologic and nonpharmacologic interventions to intensify management of poorly controlled symptoms at home. SymptomCare@Home is a model for providing telehealth. The system facilitates using evidence-based guidelines as part of a comprehensive symptom management approach. The design process and system features can be applied to other diseases and conditions.

  7. Behavioural and psychiatric symptoms in cognitive neurology.

    Robles Bayón, A; Gude Sampedro, F


    Behavioural and psychiatric symptoms (BPS) are frequent in neurological patients, contribute to disability, and decrease quality of life. We recorded BPS prevalence and type, as well as any associations with specific diagnoses, brain regions, and treatments, in consecutive outpatients examined in a cognitive neurology clinic. A retrospective analysis of 843 consecutive patients was performed, including a review of BPS, diagnosis, sensory impairment, lesion topography (neuroimaging), and treatment. The total sample was considered, and the cognitive impairment (CI) group (n=607) was compared to the non-CI group. BPS was present in 59.9% of the patients (61.3% in the CI group, 56.4% in the non-CI group). One BPS was present in 31.1%, two in 17.4%, and three or more in 11.4%. BPS, especially depression and anxiety, are more frequent in women than in men. Psychotic and behavioural symptoms predominate in subjects aged 65 and older, and anxiety in those younger than 65. Psychotic symptoms appear more often in patients with sensory impairment. Psychotic and behavioural symptoms are more prevalent in patients with degenerative dementia; depression and anxiety in those who suffer a psychiatric disease or adverse effects of substances; emotional lability in individuals with a metabolic or hormonal disorder; hypochondria in those with a pain syndrome; and irritability in subjects with chronic hypoxia. Behavioural symptoms are more frequent in patients with anomalies in the frontal or right temporal or parietal lobes, and antipsychotics constitute the first line of treatment. Leaving standard treatments aside, associations were observed between dysthymia and opioid analgesics, betahistine and statins, and between psychotic symptoms and levodopa, piracetam, and vasodilators.

  8. Behavioral and Psychological Symptoms of Dementia

    Joaquim eCerejeira


    Full Text Available Behavioral and psychological symptoms of dementia (BPSD, also known as neuropsychiatric symptoms, represent a heterogeneous group of non-cognitive symptoms and behaviors occurring in subjects with dementia. BPSD constitute a major component of the dementia syndrome irrespective of its subtype. They are as clinically relevant as cognitive symptoms as they strongly correlate with the degree of functional and cognitive impairment. BPSD include agitation, aberrant motor behavior, anxiety, elation, irritability, depression, apathy, disinhibition, delusions, hallucinations, and sleep or appetite changes. It is estimated that BPSD affect up to 90% of all dementia subjects over the course of their illness, and is independently associated with poor outcomes, including distress among patients and caregivers, long term hospitalization, misuse of medication and increased health care costs. Although these symptoms can be present individually it is more common that various psychopathological features co-occur simultaneously in the same patient. Thus, categorization of BPSD in clusters taking into account their natural course, prognosis and treatment response may be useful in the clinical practice. The pathogenesis of BPSD has not been clearly delineated but it is probably the result of a complex interplay of psychological, social and biological factors. Recent studies have emphasized the role of neurochemical, neuropathological and genetic factors underlying the clinical manifestations of BPSD. A high degree of clinical expertise is crucial to appropriately recognize and manage the neuropsychiatric symptoms in a patient with dementia. Combination of non-pharmacological and careful use of pharmacological interventions is the recommended therapeutic for managing BPSD. Given the modest efficacy of current strategies, there is an urgent need to identify novel pharmacological targets and develop new non-pharmacological approaches to improve the adverse outcomes

  9. Eating disorder symptom trajectories in adolescence: effects of time, participant sex, and early adolescent depressive symptoms.

    Allen, Karina L; Crosby, Ross D; Oddy, Wendy H; Byrne, Susan M


    Adolescence is a period of developmental risk for eating disorders and eating disorder symptoms. This study aimed to describe the prevalence and trajectory of five core eating disorder behaviours (binge eating, purging, fasting, following strict dietary rules, and hard exercise for weight control) and a continuous index of dietary restraint and eating, weight and shape concerns, in a cohort of male and female adolescents followed from 14 to 20 years. It also aimed to determine the effect of early adolescent depressive symptoms on the prevalence and trajectory of these different eating disorder symptoms. Participants (N = 1,383; 49% male) were drawn from the Western Australian Pregnancy Cohort (Raine) Study, a prospective cohort study that has followed participants from pre-birth to age 20 years. An adapted version of the Eating Disorder Examination-Questionnaire was used to assess eating disorder symptoms at ages 14, 17 and 20 years. The Beck Depression Inventory for Youth was used to assess depressive symptoms at age 14. Longitudinal changes in the prevalence of eating disorder symptoms were tested using generalised estimating equations and linear mixed models. Symptom trajectories varied according to the eating disorder symptom studied, participant sex, and the presence of depressive symptoms in early adolescence. For males, eating disorder symptoms tended to be stable (for purging, fasting and hard exercise) or decreasing (for binge eating and global symptom scores) from 14 to 17 years, and then stable to 20 years. For females, fasting and global symptom scores increased from age 14 to peak in prevalence at age 17. Rates of binge eating in females were stable from age 14 to age 17 and increased significantly thereafter, whilst rates of purging and hard exercise increased from age 14 to age 17, and then remained elevated through to age 20. Depressive symptoms at age 14 impacted on eating disorder symptom trajectories in females, but not in males. Prevention

  10. Longitudinal modelling of respiratory symptoms in children

    Schlink, Uwe; Fritz, Gisela; Herbarth, Olf; Richter, Matthias


    A panel of 277 children, aged 3-7 years, was used to study the association between air pollution (O3, SO2, NO2, and total suspended particles), meteorological factors (global radiation, maximum daytime temperature, daily averages of vapour pressure and air humidity) and respiratory symptoms. For 759 days the symptoms were recorded in a diary and modelling was based on a modification of the method proposed by Korn and Whittemore (Biometrics 35: 795-798, 1979). This approach (1) comprises an extension using environmental parameters at different time scales, (2) addresses the suitability of using the daily fraction of symptomatic individuals to account for inter-individual interactions and (3) enables the most significant weather effects to be identified. The resulting model consisted of (1) an individual specific intercept that takes account of the population's heterogeneity, (2) the individual's health status the day before, (3) a long-term meteorological effect, which may be either the squared temperature or global radiation in interaction with temperature, (4) the short-term effect of sulfur dioxide, and (5) the short-term effect of an 8-h ozone concentration above 60 µg/m3. Using the estimated parameters as input to a simulation study, we checked the quality of the model and demonstrate that the annual cycle of the prevalence of respiratory symptoms is associated to atmospheric covariates. Individuals suffering from allergy have been identified as a group of a particular susceptibility to ozone. The duration of respiratory symptoms appears to be free of scale and follows an exponential distribution function, which confirms that the symptom record of each individual follows a Poisson point-process. This supports the assumption that not only respiratory diseases, but also respiratory symptoms can be considered an independent measure for the health status of a population sample. Since a point process is described by only one parameter (namely the intensity of the

  12. Management of JJ stent-related symptoms.

    Papatsoris, Athanasios; Dellis, Athanasios; Daglas, George; Sanguedolce, Francesco


    Ureteric JJ stents are inserted in numerous pa- tients as a routine procedure. Nevertheless, the ideal JJ stent that does not cause any lower urinary tract symptoms has not been developed yet. Even special validated ques- tionnaires have been used for the assessment of JJ stent-related symtoms. For the management of such symtoms usually alpha-blockers are admin- istered. Also, studies have examined the efficacy and safety of anticholinergics and calcium channel blo- ckers. In this article we review the literature upon the management of JJ stent-related symptoms.

  13. Unspecific neurologic symptoms as possible psychogenic complaints.

    Franz, M; Schepank, H; Schellberg, D


    Prevalence and course of psychogenically influenced symptoms in neurology and their dependence on age and gender are reported. The epidemiological basis of the data is a long-term follow-up investigation of a high-risk population for about 10 years (n = 240): the Mannheim Cohort Study on Epidemiology of Psychogenic Disorders. Seven psychogenic symptoms of neurologic relevance (headache, lumbar and cervical vertebral complaints, functional vertigo, hyperkinesias, pareses, sleep and concentration disturbances) are characterized in regard to frequency, course and diagnostic significance.

  14. Nasal chondromesenchymal hamartoma with no nasal symptoms.

    Uzomefuna, Vincent


    The authors present a case of nasal chondromesenchymal hamartoma (NCMH) in an 8-year-old boy with a 4-month history of frontal headache and no symptoms of nasal obstruction, rhinorrhoea or postnasal drip. An ENT examination as well as ophthalmology assessment presented normal results. CT scan showed a lesion involving the sphenoid and ethmoid sinuses. The patient had an endoscopic resection of the lesion that was confirmed histologically to be a NCMH. Though NCMH is known to present usually in infants with obstructing nasal mass, an unusual presentation of a patient with throbbing headache without any nasal symptoms is reported here.

  15. Children's illness drawings and asthma symptom awareness.

    Gabriels, R L; Wamboldt, M Z; McCormick, D R; Adams, T L; McTaggart, S R


    This study examines the relationship between children's abilities to perceive their symptoms of asthma via several previously researched subjective and objective procedures compared with their performance on a standardized children's drawing task and scale criteria. Results indicated that girls verbalized significantly more emotions about their drawings and were better able to detect airflow changes in their small airways than boys. The Gabriels Asthma Perception Drawing Scales (GAPDS) is a promising clinical tool for assessing children's perceptions and emotions about asthma via nonverbal methods. Varying methods of measuring asthma symptom awareness are not highly correlated; thus, more than one methodology is appropriate for use with children.


    Meteyer, Karen B; Perry-Jenkins, Maureen


    We explore dyadic parenting styles and their association with first-grade children's externalizing behavior symptoms in a sample of 85 working-class, dual-earner families. Cluster analysis is used to create a typology of parenting types, reflecting the parental warmth, overreactivity, and laxness of both mothers and fathers in two-parent families. Three distinct groups emerged: Supportive Parents, Mixed-Support Parents and Unsupportive Parents. Results indicate that dyadic parenting styles were related to teacher-reported externalizing symptoms for boys but not for girls.

  1. [Negative symptoms in schizophrenia: psychotherapeutic approaches].

    Azorin, J-M; Adida, M; Belzeaux, R; Pringuey, D; Micoulaud Franchi, J-A; Simon, N; Cermolacce, M; Kaladjian, A; Fakra, E


    Although negative symptoms are recognized as a central feature of schizophrenia, their definition as well as phenomenology have long been a vexing issue. During these last years, a major progress has been made with the delineation of two underlying subdomains of negative symptoms: diminished expression and anhedonia-avolition-apathy. As current guidelines are not always in accord on the efficacy of treatments on negative symptoms, it may be tempting to re-interpret the findings of clinical trials by looking at the effects of treatments on these two subdomains. This could concern both psychotropic treatments and psychotherapeutic interventions. Furthermore, neuroimaging as well as emotional response studies have permitted to better understand the mechanism which could be at the root of diminished expression and anhedonia in schizophrenia. On this basis, new psychotherapeutic methods have been devised which, by specifically targeting these two subdomains, are likely to be more efficient on negative symptoms. Further research is warranted to test their efficacy in randomized controlled trials. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

  3. Behavioral symptoms related to cognitive impairment.

    Dillon, Carol; Serrano, Cecilia M; Castro, Diego; Leguizamón, Patricio Perez; Heisecke, Silvina L; Taragano, Fernando E


    Neuropsychiatric symptoms (NPS) are core features of Alzheimer's disease and related dementias. On one hand, behavioral symptoms in patients with mild cognitive impairment (MCI) can indicate an increased risk of progressing to dementia. On the other hand, mild behavioral impairment (MBI) in patients who usually have normal cognition indicates an increased risk of developing dementia. Whatever the cause, all dementias carry a high rate of NPI. These symptoms can be observed at any stage of the disease, may fluctuate over its course, are a leading cause of stress and overload for caregivers, and increase rates of hospitalization and early institutionalization for patients with dementia. The clinician should be able to promptly recognize NPI through the use of instruments capable of measuring their frequency and severity to support diagnosis, and to help monitor the treatment of behavioral symptoms. The aims of this review are to describe and update the construct 'MBI' and to revise the reported NPS related to prodromal stages of dementia (MCI and MBI) and dementia stages of Alzheimer's disease and frontotemporal lobar degeneration.

  8. Definition and symptoms of underactive bladder.

    Uren, Alan D; Drake, Marcus J


    Underactive bladder (UAB) is a symptom syndrome reflecting the urodynamic observation of detrusor underactivity (DU), a voiding contraction of reduced strength and/or duration, leading to prolonged or incomplete bladder emptying. An International Continence Society Working Group has described UAB as characterised by a slow urinary stream, hesitancy and straining to void, with or without a feeling of incomplete bladder emptying and dribbling, often with storage symptoms. Since DU often coexists with bladder outlet obstruction, or storage dysfunction (detrusor overactivity or incontinence), the exact contribution of the DU to the presenting complaints can be difficult to establish. The presence of voiding and post voiding lower urinary tract symptoms (LUTS) is implicitly expected in UAB, but a reduced sensation of fullness is reported by some patients, and storage LUTS are also an important factor in many affected patients. These may result from a postvoid residual, but often they do not. The storage LUTS are often the key driver in leading the patient to seek healthcare input. Nocturia is particularly common and bothersome, but what the role of DU is in all the range of influences on nocturia has not been established. Qualitative research has established a broad impact on everyday life as a result of these symptoms. In general, people appear to manage the voiding LUTS relatively well, but the storage LUTS may be problematic.

  8. High-pressure phase relations in the composition of albite NaAlSi3O8 constrained by an ab initio and quasi-harmonic Debye model, and their implications

    Deng, L.; Liu, X.; Liu, H.; Dong, J.


    The high pressure physical-chemical behaviors of feldspar in subducted slab are very important to the geodynamic process in the deep interior of the Earth. Albite (NaAlSi3O8;Ab) is one of the few end members in the feldspar family, and its high-P behavior is obviously a prerequisite to the full understanding of the physical-chemical properties of feldspar at high pressures. So far it has been well accepted that Ab breaks down to the phase assemblage of Jadeite+Stishovite(NaAlSi2O6; Jd, SiO2; St,JS hereafter) at ~9-10 GPa. The JS phase assemblage might be stable up to ~23 GPa, and eventually directly change into the phase assemblage of calcium-ferrite type NaAlSiO4 (Cf) +2St (CS hereafter). However, some independent researches suggest there is an intermediate phase Na-hollandite (Na-Hall; a phase with the composition of NaAlSi3O8 and the structure of hollandite) between JS phase assemblage transition into CS phase assemblage (Liu 1978; Tutti 2007; Sekine and Ahrens, 1992; Beck et al., 2004). Whether Na-Hall is a thermodynamic stable phase under high P-T conditions remains unknown. In this work, phase relations in the composition of albite NaAlSi3O8 at pressures up to 40 GPa were constrained by a theoretical method that combines the ab initio calculation and quasi-harmonic Debyemodel. First, the P-T dependence of the thermodynamic potentials of the individual phase, St, Cf, Jd and the hypothetical Na-Holl were derived. Our results are generally in consistent agreement with available experimental data and previous theoretical predictions. Second, the Gibbs free energy of the hypothetical Na-Holl phase was compared with that of the phase assemblages JS and CS. Our results show that the Na-Holl phase is not a thermodynamically stable phase over the studied P-T conditions of 0-40 GPa and 100-600 K, which rules it out as a possible intermediate phase along the transition path from the JS phase assemblage to CS phase assemblage. Our calculations have predicted that the JS

However, this paradigm has been challenged in recent decades by the available evidence. Recent studies have pointed out that COPD-related symptoms are not consistently perceived by patients in the same way, showing not only seasonal variation, but also changes in symptom perception during a week or even within a single day. According to the available data, patients experience the biggest increase in respiratory symptoms during the first hours of the early morning, followed by the nighttime. This variation over time is of considerable importance, since it impacts on daily life activities and health-related quality of life, as measured by a recently developed ad hoc questionnaire. Additionally, recent clinical trials have suggested that the use of rapid-onset long-acting bronchodilators may have an impact on morning symptoms, despite their current use as maintenance treatment for a determined period. Although this hypothesis is to be validated in future long-term clinical trials comparing fast-onset versus slow-onset inhaled drugs in COPD, it may bring forward a new concept of long-term bronchodilator therapy. At the present time, the two available long-acting, fast-onset bronchodilators used in the treatment of COPD are formoterol and the recently marketed indacaterol. Newer drugs have also been shown to have a rapid onset of action in preclinical

  10. A Cross-Cultural Comparison of Symptom Reporting and Symptom Clusters in Heart Failure.

    Park, Jumin; Johantgen, Mary E


    An understanding of symptoms in heart failure (HF) among different cultural groups has become increasingly important. The purpose of this study was to compare symptom reporting and symptom clusters in HF patients between a Western (the United States) and an Eastern Asian sample (China and Taiwan). A secondary analysis of a cross-sectional observational study was conducted. The data were obtained from a matched HF patient sample from the United States and China/Taiwan ( N = 240 in each). Eight selective items related to HF symptoms from the Minnesota Living with Heart Failure Questionnaire were analyzed. Compared with the U.S. sample, HF patients from China/Taiwan reported a lower level of symptom distress. Analysis of two different regional groups did not result in the same number of clusters using latent class approach: the United States (four classes) and China/Taiwan (three classes). The study demonstrated that symptom reporting and identification of symptom clusters might be influenced by cultural factors.

  11. Thyroiditis: Symptoms to sequelae - An Indian experience

    Sneha, S.; Krishna, B.A.; Madhavi, C.; Sangeeta, T.; Rijju, G.


    Introduction: Thyroiditis presents with symptoms varying from thyrotoxicosis to hypothyroidism. In fairly a large number of patients the symptoms are very subtle and hence clinical diagnosis is difficult to make without laboratory assistance. In view of this we undertook a study to assess the patterns of clinical presentation and the behavioral pattern of patients with thyroiditis. Materials and Methods: Totally 43 patients were included in the study with clinical suspicion of thyroiditis. 31 patients presented with symptoms of thyrotoxicosis while 6 patients presented with hypothyroid symptoms. Six patients presented with history of acute upper respiratory tract infection with tender thyromegaly and euthyroid status. These patients were subjected to thyroid scan (43 patients), sonography (6 patients), thyroid antibody levels estimation (43 patients), FNAC evaluation (3 patients) and T3, T4, TSH estimation (43 patients). The patients were followed up for a period of 6 months to 2 years. Clinical evaluation and T3, T4 and TSH evaluation was performed. Result: 19 of the 31 patients (61.29%) who presented with thyrotoxicosis progressed to hypothyroid state both clinically and biochemically. 11 of the 31 patients (35.48%) reverted to euthyroid status. One patient continued to maintain thyrotoxic state at the end of 2 years and was treated with antithyroid measures. In the hypothyroid group of six patients, four patients continued to maintain hypothyroid state while two patients reverted to euthyroid status during follow up. In the euthyroid group of six patients four patients developed hypothyroid status and the other two patients remained euthyroid. The 99m- Tco4 scan demonstrated poor and patchy uptake in all the patients. Conclusion: Our study demonstrated that majority of the patients (72.09%) of thyroiditis present with thyrotoxic symptoms. The sequelae of hypothyroidism was seen in 61.29% of patients in this group. We observed an interesting finding of patients

  12. The Trapeziometacarpal Arthrosis Symptoms and Disability Questionnaire

    Becker, Stéphanie J. E.; Teunis, Teun; Ring, David; Vranceanu, Ana-Maria


    Background: Symptoms and disability at the trapeziometacarpal (TMC) joint are typically assessed with general measures that may not be able to accurately discriminate between TMC arthrosis–specific versus other hand and arm condition concerns. The objective was to develop and preliminary validate the Trapeziometacarpal Arthrosis Symptoms and Disability (TASD) questionnaire designed to assess symptoms and disability at the TMC joint. Methods: English-speaking patients (50 years or older) were enrolled in 1 of 2 samples (sample 1, 64 patients specifically presented for treatment of TMC arthrosis; sample 2, 64 patients received an incidental diagnosis of previously undiagnosed TMC arthrosis when presenting for treatment of another, not thumb-related condition). Principal component analysis identified the number of subscales (factors) and factor loadings of all items (ie, structural construct validity). Internal consistency was assessed with Cronbach alpha. Convergent, discriminant, and known-groups construct validity of the subscales were assessed with Spearman correlations. Results: The final TASD has 12 items and 2 subscales, as confirmed by principal component analysis: symptoms (7 items) and disability (5 items). The subscales’ internal consistency was good to excellent in both samples. The TASD showed good convergent validity as evidenced by moderate to strong correlations between both subscales and upper extremity disability, pain intensity, depression, self-efficacy, and key pinch strength (sample 1). The TASD also showed good discriminant, and good known-groups validity. Conclusions: The concise TASD is useful in assessing symptoms and disability related to TMC arthrosis, has a simple scoring system and administration mode (self-administered), and is free.

  13. Schizophrenia and smoking: impact on negative symptoms

    Miriam Saliba


    Full Text Available Introduction: it has been hypothesized that individuals with schizophrenia use nicotine to reduce negative symptoms and improve cognitive function. There is an inconsistency in the literature suggesting that nicotine could help decrease negative symptoms in schizophrenic patients. Objective: to investigate the effects of nicotine on the expression of the negative symptoms in smokers and non-smokers with schizophrenia. Methods: a cross sectional study, conducted between April and August 2016, 100 inpatients with schizophrenia (54 smokers and 46 non-smokers diagnosed according to DSM-V, at Psychiatric Hospital of the Cross Lebanon, were compared to changes in clinical parameters using CDSS, PANSS, and nicotine dependence using FTND. The Student’s t-test was used to compare between 2 groups, while the ANOVA test was used to compare between 3 or more groups. For categorical variables, the chi-2 test was used. Results: the mean age was 47.16 years (SD = 7.14 for smokers compared to 47.02 years (SD = 7.92 for non-smokers. 64.8% of smokers were males versus 45.7% of non-smokers. Smoking (high nicotine dependence significantly decreases the PANSS negative symptoms score between the 2 groups (p .05 for both variables. Discussion and conclusion: this study is the first to investigate the relationship between the expression of negative symptoms in individuals with schizophrenia and smoking in Lebanon. Cigarette smoking rates remain remarkably high in patients with schizophrenia. Smoking is a complex process which involves psychopathological, biochemical and neuropharmacological aspects among schizophrenic patients. Further studies are needed to acknowledge these findings and the reasons behind it.

  14. Symptom recovery after thoracic surgery: Measuring patient-reported outcomes with the MD Anderson Symptom Inventory.

    Fagundes, Christopher P; Shi, Qiuling; Vaporciyan, Ara A; Rice, David C; Popat, Keyuri U; Cleeland, Charles S; Wang, Xin Shelley


    Measuring patient-reported outcomes (PROs) has become increasingly important for assessing quality of care and guiding patient management. However, PROs have yet to be integrated with traditional clinical outcomes (such as length of hospital stay), to evaluate perioperative care. This study aimed to use longitudinal PRO assessments to define the postoperative symptom recovery trajectory in patients undergoing thoracic surgery for lung cancer. Newly diagnosed patients (N = 60) with stage I or II non-small cell lung cancer who underwent either standard open thoracotomy or video-assisted thoracoscopic surgery lobectomy reported multiple symptoms from before surgery to 3 months after surgery, using the MD Anderson Symptom Inventory. We conducted Kaplan-Meier analyses to determine when symptoms returned to presurgical levels and to mild-severity levels during recovery. The most-severe postoperative symptoms were fatigue, pain, shortness of breath, disturbed sleep, and drowsiness. The median time to return to mild symptom severity for these 5 symptoms was shorter than the time to return to baseline severity, with fatigue taking longer. Recovery from pain occurred more quickly for patients who underwent lobectomy versus thoracotomy (8 vs 18 days, respectively; P = .022). Patients who had poor preoperative performance status or comorbidities reported higher postoperative pain (all P < .05). Assessing symptoms from the patient's perspective throughout the postoperative recovery period is an effective strategy for evaluating perioperative care. This study demonstrates that the MD Anderson Symptom Inventory is a sensitive tool for detecting symptomatic recovery, with an expected relationship among surgery type, preoperative performance status, and comorbid conditions.

  15. [Psychosocial factors predicting postnatal anxiety symptoms and their relation to symptoms of postpartum depression].

    Navarrete, Laura Elena; Lara-Cantú, María Asunción; Navarro, Claudia; Gómez, María Eugenia; Morales, Francisco


    To study perinatal anxiety symptoms in a sample of Mexican mothers. A) To evaluate the effect of certain psychosocial factors during pregnancy on anxiety symptoms at two postpartum time intervals; and B) to determine whether this symptomatology is related to symptoms of postnatal depression. In this secondary data analysis, 156 women were interviewed during pregnancy (T1): 149 were interviewed again at 6 weeks postpartum (T2) and 156 at 4-6 months postpartum (T3). Subjects were selected from women seeking prenatal attention at three health centers in Mexico City who presented with depressive symptomatology and/or previous history of depression. Two models were subjected to multivariate regression analysis to determine the influence of psychosocial factors in pregnancy (age, education, partner status, social support [APGAR], stress events, self-esteem [Coopersmith], depressive symptomatology [BDI-II], and anxiety [SCL-90]) on anxiety symptomatology (SCL-90) in T2 and T3. Two additional linear regression analyses were performed to evaluate the influence of prenatal anxiety symptomatology (SCL-90) on postpartum depression symptoms (BDI-II), one for each postnatal period (T2, T3). The variables that predicted postpartum anxiety symptomatology in T2 were anxiety symptoms and lack of social support; in T3 they were anxiety symptoms, lack of a partner, and lack of social support. Prenatal anxiety symptoms predicted postpartum depressive symptomatology at both postpartum intervals (T2, T3). Untreated prenatal anxiety symptomatology is predictive of symptoms of anxiety and depression in the postpartum period, suggesting the need for timely detection and treatment. Women lacking social support or partners are a population particularly vulnerable to anxiety symptoms, and merit interventions that address these issues.

  16. Early maternal depressive symptom trajectories: Associations with 7-year maternal depressive symptoms and child behavior.

    Buckingham-Howes, Stacy; Oberlander, Sarah E; Wang, Yan; Black, Maureen M


    This study examines potential mechanisms linking maternal depressive symptoms over 2 years postpartum with child behavior problems at school-age in a sample of adolescent mothers and their first-born child. Potential mechanisms include: mother-reported caregiving engagement at 6 months; observed parental nurturance and control, and child competence and affect at 24 months; and mother-reported resilience at 7 years based on achievement of adult developmental tasks. One hundred eighteen low-income African American adolescent mothers were recruited at delivery and followed through child age 7 years. Maternal depressive symptom trajectories over 24 months were estimated (low, medium, and high) based on mother-reported depressive symptoms. Direct and indirect associations between depressive symptom trajectories with 7-year maternal depressive symptoms and child behavior problems were examined. The high maternal depressive symptom trajectory was associated with 7-year maternal depressive symptoms (b = 5.52, SE = 1.65, p child internalizing problems (b = 7.60, SE = 3.12, p = .02) and externalizing problems (b = 6.23, SE = 3.22, p = .05). Caregiving engagement among high depressive symptom trajectory mothers was significantly associated with observed child affect (b = -0.21, SE = 0.11, p = 0.05). Parental nurturance in toddlerhood mediated the association between high maternal depressive symptom trajectory and child internalizing problems at 7 years (indirect effect b = 2.33, 95% CI: 0.32-5.88). Findings suggest that family based interventions to promote parenting and adolescent resiliency strengthening may be beneficial in this population.

  17. Menopausal symptoms: do life events predict severity of symptoms in peri- and post-menopause?

    Pimenta, Filipa; Leal, Isabel; Maroco, João; Ramos, Catarina


    Hormonal changes during menopausal transition are linked to physical and psychological symptoms' emergence. This study aims to explore if life events predict menopausal symptoms. This cross-sectional research encompasses a community sample of 992 women who answered to socio-demographic, health, menopause-related and lifestyle questionnaires; menopausal symptoms and life events were assessed with validated instruments. Structural equation modeling was used to build a causal model. Menopausal status predicted only three symptoms: skin/facial hair changes (β=.136; p=.020), sexual (β=.157; p=.004) and, marginally, vasomotor symptoms (β=.094; p=.054). Life events predicted depressive mood (β=-.391; p=.002), anxiety (β=-.271; p=.003), perceived cognitive impairment (β=-.295; p=.003), body shape changes (β=-.136; p=.031), aches/pain (β=-.212; p=.007), skin/facial hair changes (β=-.171; p=.021), numbness (β=-.169; p=.015), perceived loss of control (β=-.234; p=.008), mouth, nails and hair changes (β=-.290; p=.004), vasomotor (β=-.113; p=.044) and sexual symptoms (β=-.208; p=.009). Although women in peri- and post-menopausal manifested higher symptoms' severity than their pre-menopausal counterparts, only three of the menopausal symptoms assessed were predicted by menopausal status. Since the vast majority of menopausal symptoms' severity was significantly influenced by the way women perceived their recent life events, it is concluded that the symptomatology exacerbation, in peri- and post-menopausal women, might be due to life conditions and events, rather than hormonal changes (nonetheless, the inverse influence should be investigated in future studies). Therefore, these should be accounted for in menopause-related clinical and research settings. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

  18. High Baseline Postconcussion Symptom Scores and Concussion Outcomes in Athletes.

    Custer, Aimee; Sufrinko, Alicia; Elbin, R J; Covassin, Tracey; Collins, Micky; Kontos, Anthony


    Some healthy athletes report high levels of baseline concussion symptoms, which may be attributable to several factors (eg, illness, personality, somaticizing). However, the role of baseline symptoms in outcomes after sport-related concussion (SRC) has not been empirically examined. To determine if athletes with high symptom scores at baseline performed worse than athletes without baseline symptoms on neurocognitive testing after SRC. Cohort study. High school and collegiate athletic programs. A total of 670 high school and collegiate athletes participated in the study. Participants were divided into groups with either no baseline symptoms (Postconcussion Symptom Scale [PCSS] score = 0, n = 247) or a high level of baseline symptoms (PCSS score > 18 [top 10% of sample], n = 68). Participants were evaluated at baseline and 2 to 7 days after SRC with the Immediate Post-concussion Assessment and Cognitive Test and PCSS. Outcome measures were Immediate Post-concussion Assessment and Cognitive Test composite scores (verbal memory, visual memory, visual motor processing speed, and reaction time) and total symptom score on the PCSS. The groups were compared using repeated-measures analyses of variance with Bonferroni correction to assess interactions between group and time for symptoms and neurocognitive impairment. The no-symptoms group represented 38% of the original sample, whereas the high-symptoms group represented 11% of the sample. The high-symptoms group experienced a larger decline from preinjury to postinjury than the no-symptoms group in verbal (P = .03) and visual memory (P = .05). However, total concussion-symptom scores increased from preinjury to postinjury for the no-symptoms group (P = .001) but remained stable for the high-symptoms group. Reported baseline symptoms may help identify athletes at risk for worse outcomes after SRC. Clinicians should examine baseline symptom levels to better identify patients for earlier referral and treatment for their

  19. The profile of psychiatric symptoms exacerbated by methamphetamine use.

    McKetin, Rebecca; Dawe, Sharon; Burns, Richard A; Hides, Leanne; Kavanagh, David J; Teesson, Maree; McD Young, Ross; Voce, Alexandra; Saunders, John B


    Methamphetamine use can produce symptoms almost indistinguishable from schizophrenia. Distinguishing between the two conditions has been hampered by the lack of a validated symptom profile for methamphetamine-induced psychiatric symptoms. We use data from a longitudinal cohort study to examine the profile of psychiatric symptoms that are acutely exacerbated by methamphetamine use. 164 methamphetamine users, who did not meet DSM-IV criteria for a lifetime primary psychotic disorder, were followed monthly for one year to assess the relationship between days of methamphetamine use and symptom severity on the 24-item Brief Psychiatric Rating Scale. Exacerbation of psychiatric symptoms with methamphetamine use was quantified using random coefficient models. The dimensions of symptom exacerbation were examined using principal axis factoring and a latent profile analysis. Symptoms exacerbated by methamphetamine loaded on three factors: positive psychotic symptoms (suspiciousness, unusual thought content, hallucinations, bizarre behavior); affective symptoms (depression, suicidality, guilt, hostility, somatic concern, self-neglect); and psychomotor symptoms (tension, excitement, distractibility, motor hyperactivity). Methamphetamine use did not significantly increase negative symptoms. Vulnerability to positive psychotic and affective symptom exacerbation was shared by 28% of participants, and this vulnerability aligned with a past year DSM-IV diagnosis of substance-induced psychosis (38% vs. 22%, χ(2)(df1)=3.66, p=0.056). Methamphetamine use produced a symptom profile comprised of positive psychotic and affective symptoms, which aligned with a diagnosis of substance-induced psychosis, with no evidence of a negative syndrome.

  20. Sequential imaging of intraneural sciatic nerve endometriosis provides insight into symptoms of cyclical sciatica.

    Capek, Stepan; Amrami, Kimberly K; Howe, Benjamin M; Collins, Mark S; Sandroni, Paola; Cheville, John C; Spinner, Robert J


    Endometriosis of the nerve often remains an elusive diagnosis. We report the first case of intraneural lumbosacral plexus endometriosis with sequential imaging at different phases of the menstrual cycle: during the luteal phase and menstruation. Compared to the first examination, the examination performed during the patient's period revealed the lumbosacral plexus larger and hyperintense on T2-weighted imaging. The intraneural endometriosis cyst was also larger and showed recent hemorrhage. Additionally, this case represents another example of perineural spread of endometriosis from the uterus to the lumbosacral plexus along the autonomic nerves and then distally to the sciatic nerve and proximally to the spinal nerves.

  1. [Respiratory symptoms and atmospheric pollution and respiratory symptoms in the general population].

    Simon, I; Charpin, D


    Epidemiological studies on air pollution have mainly been interested in the effects of short- or long-term exposure on patients suffering from respiratory illnesses. Fewer studies have addressed the acute effects of air pollution on respiratory symptoms in the general population. We conducted a review of the literature over the last 16years that has addressed the impact of atmospheric pollution on respiratory symptoms in the general population to estimate the magnitude of effect. The majority of studies demonstrated a significant association between exposure to air pollutants and the occurrence of respiratory symptoms, without any threshold. Although a link between atmospheric pollution and respiratory symptoms has been demonstrated, knowledge of the effects of specific air pollutants and the effect of pollution on particular vulnerable groups (infants, young children, the elderly) is still limited. There is a need for further studies in this area. Copyright 2010 SPLF. Published by Elsevier Masson SAS. All rights reserved.

  2. Next-generation negative symptom assessment for clinical trials: validation of the Brief Negative Symptom Scale.

    Strauss, Gregory P; Keller, William R; Buchanan, Robert W; Gold, James M; Fischer, Bernard A; McMahon, Robert P; Catalano, Lauren T; Culbreth, Adam J; Carpenter, William T; Kirkpatrick, Brian


    The current study examined the psychometric properties of the Brief Negative Symptom Scale (BNSS), a next-generation rating instrument developed in response to the NIMH sponsored consensus development conference on negative symptoms. Participants included 100 individuals with a DSM-IV diagnosis of schizophrenia or schizoaffective disorder who completed a clinical interview designed to assess negative, positive, disorganized, and general psychiatric symptoms, as well as functional outcome. A battery of anhedonia questionnaires and neuropsychological tests were also administered. Results indicated that the BNSS has excellent internal consistency and temporal stability, as well as good convergent and discriminant validity in its relationships with other symptom rating scales, functional outcome, self-reported anhedonia, and neuropsychological test scores. Given its brevity (13-items, 15-minute interview) and good psychometric characteristics, the BNSS can be considered a promising new instrument for use in clinical trials.

  5. Clinical symptoms of food allergy/intolerance in children

    Halken, S


    Food allergy is principally a problem in infancy and early childhood. Food allergy/intolerance may cause a broad spectrum of symptoms and signs in children, including generalized reactions, such as anaphylactic shock. Reactions are localized mainly in the gastrointestinal tract, but food allergy....../intolerance may also cause local symptoms in other organs such as the skin and the respiratory tract. About 50-70% demonstrate cutaneous symptoms, 50-60% gastrointestinal symptoms, and 20-30% respiratory symptoms. Among young children with food allergy/intolerance the majority have two or more symptoms...... with symptoms occurring in two or more organ systems. The symptoms occur primarily within a few minutes after food exposure (immediate reactions), however delayed reactions in the skin, gastrointestinal tract and lungs may also occur. Among children with symptoms suggestive of food allergy...

  6. Evaluation and treatment of colonic symptoms.

    Pasanen, Mark E


    Important considerations for constipation include: 1. Initial evaluation should evaluate for fecal incontinence, fecal impaction, medication side effects, concerning symptoms, underlying medical or metabolic issues and irritable bowel syndrome. 2. History and examination should be used to determine if a defecatory disorder is most likely. a. If defecatory disorder is likely, testing with balloon expulsion or anal manometry can be considered and, if confirmed, treatment with biofeedback (if testing not available, it is reasonable to trial fiber and laxatives because many patients have a mixed disorder). b. If it is unlikely, proceed with trial of fiber and/or osmotic laxatives. 3. If continued symptoms, consider trial of newer agent (lubiprostone or linaclotide). 4. If ineffective, consider testing for colon transit time and referral to gastroenterology. Copyright © 2014 Elsevier Inc. All rights reserved.

  7. Symptom rating scale for assessing hyperthyroidism.

    Klein, I; Trzepacz, P T; Roberts, M; Levey, G S


    A hyperthyroid symptom scale (HSS) was designed and administered to ten subjects with untreated Graves' disease. All subjects had clinical and chemical evidence of hyperthyroidism and reproducible HSS scores of 20 or more points. During sequential treatments with propranolol hydrochloride (phase 2) followed by propylthiouracil (phase 3) there was a significant decline in the HSS scores at each phase. Accompanying the decrease in HSS scores was a decrease in heart rate, but there was no change in thyroid function test results at phase 2 and a decrease in heart rate, thyroid function test results, and goiter size at phase 3. This new scale includes ten categories of symptoms, it is sensitive to changes in both the adrenergic and metabolic components of hyperthyroidism, and it is useful in the clinical assessment and management of patients with thyrotoxicosis.

  8. [Symptoms of Celiac disease in childhood].

    Mouterde, O; Dumant, C; Mallet, E


    The knowledge regarding celiac disease has increased dramatically in recent years, due to the availability of accurate serologic markers. Mass screening studies have shown that the prevalence of sensitization can be as high as 1/80. The range of symptoms is wide, from the classic growth failure, denutrition and diarrhea in infancy to clinically and histologically asymptomatic sensitized subjects. The interest of a routine mass screening is debated. The classical celiac disease in infancy is well known. Atypical symptoms and potentially associated disease are more frequent and potentially confounding. Physicians should be aware of any clue for celiac disease in atypical cases in order to improve the diagnostic yield, and therefore avoiding short or long term consequences.

  9. Bulimic symptoms and the social withdrawal syndrome.

    Rotenberg, Ken J; Bharathi, Carla; Davies, Helen; Finch, Tom


    One hundred and thirty-seven undergraduates (81 females; mean age = 21 years-10 months) completed the Bulimic SEDS subscale and standardized measures of trust beliefs in close others (mother, father, and friend), disclosure to them, and loneliness. Structural Equation Modelling yielded: (1) a negative path between Bulimic Symptoms and trust beliefs, (2) a positive path between trust beliefs and disclosure, (3) a negative path between trust beliefs and loneliness, and (4) a negative path between disclosure and loneliness. As expected, trust beliefs statistically mediated the relations between Bulimic Symptoms and both disclosure and loneliness and disclosure statistically mediated the relation between trust beliefs and loneliness. The findings supported the conclusion that individuals with bulimia nervosa are prone to the social withdrawal syndrome comprising a coherent and integrated pattern of low trust beliefs in close others, low disclosure to close others, and high loneliness.

  10. Patients with persistent medically unexplained physical symptoms

    A, Aamland; Malterud, Kirsti; Werner, E.


    for all variables and split analysis on gender and age. RESULTS: The GPs registered 526 patients among their total of 17 688 consultations, giving a consultation prevalence of persistent MUPS of 3%. The mean age of patients was 46 years, and 399 (76%) were women. The most frequent group of symptoms...... was musculoskeletal problems, followed by asthenia/fatigue. There was no significant gender difference in symptom pattern. Almost half of the patients were currently working (45%), significantly more men. The major GP management strategy was supportive counseling. CONCLUSION: A consultation prevalence rate of 3......% implies that patients with persistent MUPS are common in general practice. Our study disclosed heterogeneity among the patients such as differences in employment status, which emphasizes the importance of personalized focus rather than unsubstantiated stereotyping of "MUPS patients" as a group....

  11. Emotion work within eldercare and depressive symptoms

    Jakobsen, Louise M.; Jorgensen, Anette F. B.; Thomsen, Birthe L.


    Background: Danish professional caregivers have high rates of depressive symptoms. One proposed cause is exposure to emotion work. However, emotion work is usually measured by self-report which may bias results. Objectives: The objective of this study was to examine the association of emotion work......, externally observed at the workplace, with self-reported depressive symptoms of professional caregivers. Design and data sources: The study was a cross-sectional observational study.

    Wold, P N


    Patients with Major Affective Disorder (MAD), Secondary Depression, Panic Disorder, and bulimia with and without MAD, were given the Eating Disorder Inventory, the Beck Depression Inventory, and the General Behavior Inventory at presentation. It was found that patients with MAD have a triad of eating disorder symptoms: a disturbance in interoceptive awareness, the sense of ineffectiveness, and a tendency toward bulimia. The data supported the concept that the sense of ineffectiveness is secon...

  13. Recognizing flu-like symptoms from videos.

    Thi, Tuan Hue; Wang, Li; Ye, Ning; Zhang, Jian; Maurer-Stroh, Sebastian; Cheng, Li


    Vision-based surveillance and monitoring is a potential alternative for early detection of respiratory disease outbreaks in urban areas complementing molecular diagnostics and hospital and doctor visit-based alert systems. Visible actions representing typical flu-like symptoms include sneeze and cough that are associated with changing patterns of hand to head distances, among others. The technical difficulties lie in the high complexity and large variation of those actions as well as numerous similar background actions such as scratching head, cell phone use, eating, drinking and so on. In this paper, we make a first attempt at the challenging problem of recognizing flu-like symptoms from videos. Since there was no related dataset available, we created a new public health dataset for action recognition that includes two major flu-like symptom related actions (sneeze and cough) and a number of background actions. We also developed a suitable novel algorithm by introducing two types of Action Matching Kernels, where both types aim to integrate two aspects of local features, namely the space-time layout and the Bag-of-Words representations. In particular, we show that the Pyramid Match Kernel and Spatial Pyramid Matching are both special cases of our proposed kernels. Besides experimenting on standard testbed, the proposed algorithm is evaluated also on the new sneeze and cough set. Empirically, we observe that our approach achieves competitive performance compared to the state-of-the-arts, while recognition on the new public health dataset is shown to be a non-trivial task even with simple single person unobstructed view. Our sneeze and cough video dataset and newly developed action recognition algorithm is the first of its kind and aims to kick-start the field of action recognition of flu-like symptoms from videos. It will be challenging but necessary in future developments to consider more complex real-life scenario of detecting these actions simultaneously from

  14. [Clinical symptoms and signs in Kimmerle anomaly].

    Split, Wojciech; Sawrasewicz-Rybak, Małgorzata


    The aim of the study was to consider Kimmerle anomaly (ponticulus posterior of the atlas) as an anatomic variant, which can cause a set of clinical symptoms and signs. A hundred and eight patients, 58 females and 50 males at the age of 18-59 years (M. 36.9 years, SD = 9.6) with radiologically verified Kimmerle anomaly were examined. A control group comprised 40 healthy subjects at the similar age range. The diagnosis of headaches was based on the criteria proposed by the IHS. A character of headaches, their localization, frequency, duration, number of days with headaches per year, circumstances associated with their onset and concomitant symptoms were evaluated. All the patients were subjected to electrophysiological studies (ENG, EEG and VEP). The results were statistically analyzed using a SPSS/PC+ computer system. It was revealed that clinical symptoms and signs in Kimmerle anomaly occurred most frequently in the third and fourth decade of life (65% of cases). These were most often tension-type headaches (50% of cases with headaches), vascular headaches (26% of cases) and neuralgia (24% of cases). Intensity of headaches was high. Headaches were accompanied by other complaints like vertigo (59% of cases) and in one third of cases--nausea. About 10% of patients also suffered from vomiting, paresthesia, dizziness, short periods of loss of consciousness. Sporadically--tinitus, drop attack, and vegetative symptoms. In cases without pain the most frequent signs were short periods of loss of consciousness, dizziness, and also nausea and dizziness. The EEG examination revealed pathology in 40% of patients with Kimmerle anomaly. The ENG examination in more than 33% of anomaly cases showed injury in the central part of vestibular system. Improper answers were reported in about 75% of the patients during the VEP examination.

  15. Transvestism as a Symptom: A Case Series

    Anupama, M.; Gangadhar, K. H.; Shetty, Vandana B.; Dip, P. Bhadja


    Transvestism, commonly termed as cross-dressing, means to dress in the clothing of opposite sex. We describe a series of three cases with transvestism as one of their primary complaints. The discussion sheds light on the various ways in which transvestism as a symptom can present in Psychiatry. In the first two cases, there was lower intelligence. In first and third case, there were other paraphilia along with transvestism. Second case had co-morbid obsessive-compulsive disorder (OCD) and had...

  16. [Negative symptoms, emotion and cognition in schizophrenia].

    Fakra, E; Belzeaux, R; Azorin, J-M; Adida, M


    For a long time, treatment of schizophrenia has been essentially focussed on positive symptoms managing. Yet, even if these symptoms are the most noticeable, negative symptoms are more enduring, resistant to pharmacological treatment and associated with a worse prognosis. In the two last decades, attention has shift towards cognitive deficit, as this deficit is most robustly associated to functional outcome. But it appears that the modest improvement in cognition, obtained in schizophrenia through pharmacological treatment or, more purposely, by cognitive enhancement therapy, has only lead to limited amelioration of functional outcome. Authors have claimed that pure cognitive processes, such as those evaluated and trained in lots of these programs, may be too distant from real-life conditions, as the latter are largely based on social interactions. Consequently, the field of social cognition, at the interface of cognition and emotion, has emerged. In a first part of this article we examined the links, in schizophrenia, between negative symptoms, cognition and emotions from a therapeutic standpoint. Nonetheless, investigation of emotion in schizophrenia may also hold relevant premises for understanding the physiopathology of this disorder. In a second part, we propose to illustrate this research by relying on the heuristic value of an elementary marker of social cognition, facial affect recognition. Facial affect recognition has been repeatedly reported to be impaired in schizophrenia and some authors have argued that this deficit could constitute an endophenotype of the illness. We here examined how facial affect processing has been used to explore broader emotion dysfunction in schizophrenia, through behavioural and imaging studies. In particular, fMRI paradigms using facial affect have shown particular patterns of amygdala engagement in schizophrenia, suggesting an intact potential to elicit the limbic system which may however not be advantageous. Finally, we

  18. Musculoskeletal symptoms in pharmaceutical sales representatives.

    Sang, Katherine; Gyi, Diane; Haslam, Cheryl


    Musculoskeletal disorders (MSDs) are a leading cause of work-related ill health. Existing literature indicates that pharmaceutical sales representatives (PSRs) report a high prevalence of MSDs, possibly exacerbated by the nature of work (prolonged driving and manual handling). In addition, they experience difficulty in accessing occupational health services. To assess the prevalence of musculoskeletal symptoms and associated risk factors among PSRs in order to assist their occupational health management through raising risk awareness. A self-completed questionnaire distributed to 205 PSRs within a UK pharmaceutical company was used to assess the prevalence of musculoskeletal symptoms, psychosocial factors, work tasks undertaken and company car use. To assist understanding of work tasks and organizational factors, semi-structured interviews were undertaken with a sample of 12 key personnel. The questionnaire response rate was 68%. PSRs reported high mileage and 100% reported working from the car in a typical day. Forty-seven per cent reported both manual handling for > or = 4 h/day and 'often' or 'sometimes' working from the car. Fifty-seven per cent reported low back symptoms in the last 12 months. Interview data revealed issues relating to car choice, storage in the boot and working from the car, which should be considered when developing priorities for preventive management of MSDs. Musculoskeletal symptoms appear to be a problem for PSRs, with risk factors reported as prolonged driving, sitting in the car, working from the car and manual handling. Interventions to facilitate their occupational health management should focus on raising awareness of the risks of prolonged driving and working from the car.

    Antal, András; Kocsis, Béla


    The authors present a case of enterobiasis of the appendix. Enterobius infection is an uncommon cause of acute appendicitis. Preoperative diagnosis of pinworm infestation is almost impossible unless there is a strong clinical suspicion. Parasites may produce symptoms which resemble acute appendicitis. Careful observation of the appendix stump may lead to intraoperative diagnosis of enterobiasis. A quick diagnosis and appropriate treatment may prevent future complications.

  4. Psychiatric Symptoms in Patients with Alopecia Areata



    Full Text Available Background and Design: Alopecia areata is a chronic inflammatory disease characterized by sudden hair loss. Existing evidence suggests that alopecia areata may be associated with personality traits altering the susceptibility to stress and psychiatric conditions associated with stress. The aim of this study was to compare the intensity of depressive and anxiety symptoms and the level of alexithymia in patients with alopecia areata and healthy control subjects.Materials and methods: Fifty patients with the diagnosis of alopecia areata and 30 healthy volunteers were compared in terms of scores of Beck depression inventory, Beck anxiety inventory, and Toronto alexithymia scale.Results: There were no statistically significant differences between alopecia areata cases and healthy controls regarding intensity of anxiety and level of alexythimia (p=0.053 and p=0.120, respectively. The intensity of depressive symptoms exhibited by alopecia areata patients was found to be significantly higher than that in healthy controls (p=0.010 and there was no statistically significant relationship between intensity of depressive symptoms and duration of the current alopecia areata episode (p=0.873.Conclusion: It is suggested that psychiatric evaluation should also be performed in all alopecia areata cases during the clinical follow-up period.

    Bipolar disorder in adolescents is a serious mental illness with problematic diagnosis that adversely affects social, academic, emotional, and family functioning. The objective of this study was to analyze features of premorbid and clinical symptoms, comorbidity, and course of bipolar disorder in adolescence. Data for analysis were collected from all case histories (N=6) of 14-18-year-old patients, hospitalized with diagnosis of bipolar disorder in the Unit of Children's and Adolescents' Psychiatry, Department of Psychiatry, Hospital of Kaunas University of Medicine, during the period from 2000 to 2005. Analysis of bipolar disorder course showed that five patients previously had been diagnosed with an episode of depression. The most frequent symptoms typical to bipolar disorder were disobedience and impulsive behavior, rapid changes of mood. The most common premorbid features were frequent changes of mood, being active in communication, hyperactive behavior. Adolescence-onset bipolar disorder was frequently comorbid with emotionally instable personality disorder, borderline type. Findings of the study confirm the notion that oppositional or impulsive behavior, rapid changes of mood without any reason, dysphoric mood and euphoric mood episodes with increased energy were cardinal symptoms of bipolar disorder with mania in adolescents. Most frequent premorbid features of these patients were quite similar to attention-deficit/hyperactivity disorder making differential diagnosis problematic.

  6. Housework, paid work and psychiatric symptoms

    Vilma S Santana


    Full Text Available OBJECTIVE: To evaluate the hypothesis that work burden, the simultaneous engagement in paid work and unpaid family housework, is a potential risk factor for psychiatric symptoms among women. METHODS: A cross-sectional study was carried out with 460 women randomly selected from a poor area of the city of Salvador, Brazil. Women between 18 to 70 years old, who reported having a paid occupation or were involved in unpaid domestic activities for their families, were eligible. Work burden-related variables were defined as: a double work shift, i.e., simultaneous engagement in a paid job plus unpaid housework; and b daily working time. Psychiatric symptoms were collected through a validated questionnaire, the QMPA. RESULTS: Positive, statistically significant associations between high (>7 symptoms QMPA scores and either double work shift (prevalence ratio -- PR=2.04, 95% confidence interval -- CI: 1.16, 2.29 or more than 10 hours of daily work time (PR=2.29, 95% CI: 1.96, 3.43 were found after adjustment for age, marital status and number of pre-school children. CONCLUSIONS: Major correlates of high QMPA scores are work burden variables. Being married or having pre-school children are also associated with high QMPA scores only when associated with work burden.

  8. Creutzfeldt-Jakob Disease and Psychiatric Symptoms

    Soner Cakmak


    Full Text Available Creutzfeldt-Jakob disease is a rapidly progressive, degenerative slow virus infection disease of central nervous system. Based on etiologic origins, four different Creutzfeldt-Jakob disease subtypes have been identified: sporadic, genetic, iatrogenic and variant. The clinical course generally begin with apathy, irritability, behavioral changes, speech problems, memory deterioration, rapidly progresses and concludes with death over a period of 3-12 months. Symptoms are observed secondary to brain cortex, cerebellum, corticospinal tracts, spinal anterior horn cells and basal ganglia damage. Unusual (%5-10 cases can survive up to 2 years. The initial symptoms of disease can be sudden which resultsin adjustment problems leading patients to seek psychiatric help. Patients could receive different diagnosis such as psychosis, depression with psychotic features, and treatments at this stages. Early diagnosis is crucial because of management of the disease and treatment approaches. In this article diagnosis and clinical features of Creutzfeldt-Jakob Disease and related psychiatric symptoms have been briefly reviewed. [Archives Medical Review Journal 2013; 22(4.000: 631-643

  9. Narcissistic Symptoms in German School Shooters.

    Bondü, Rebecca; Scheithauer, Herbert


    School shooters are often described as narcissistic, but empirical evidence is scant. To provide more reliable and detailed information, we conducted an exploratory study, analyzing police investigation files on seven school shootings in Germany, looking for symptoms of narcissistic personality disorder as defined by the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV) in witnesses' and offenders' reports and expert psychological evaluations. Three out of four offenders who had been treated for mental disorders prior to the offenses displayed detached symptoms of narcissism, but none was diagnosed with narcissistic personality disorder. Of the other three, two displayed narcissistic traits. In one case, the number of symptoms would have justified a diagnosis of narcissistic personality disorder. Offenders showed low and high self-esteem and a range of other mental disorders. Thus, narcissism is not a common characteristic of school shooters, but possibly more frequent than in the general population. This should be considered in developing adequate preventive and intervention measures. © The Author(s) 2014.

    Abstract Parkinson disease (PD) is usually accompanied by numerous nonmotor symptoms (NMS), such as neuropsychiatric symptoms, sleep disorders, autonomic dysfunctions, and sensory disturbances. However, it is not clear that the factors influencing the occurrence of NMS and its sequence with motor symptoms (MS). We conducted comprehensive assessments of NMS by using 13 scales in 1119 PD patients. A total of 70.8% PD patients present NMS. Olfactory dysfunction tends to occur in PD patients with older age, more severe depression, sleep problems, and autonomic dysfunctions. Older patients are more likely to have olfactory dysfunction before MS than younger patients. Rapid eye movement behavior disorder is more prone to happen in patients with older age, older onset age, more severe depression, sleep problems, and autonomic dysfunctions. Patients with rapid eye movement behavior disorder before MS are older in onset age than after group. Olfactory dysfunction, constipation, rapid eye movement behavior disorder, and depression, as early warning NMSs of PD, connected to each other. There is a clinical heterogeneity that older patients are more likely to have NMS before MS, while younger patients are opposite. PMID:27977578

  16. The development of the Canberra symptom scorecard: a tool to monitor the physical symptoms of patients with advanced tumours

    Barresi, Margherita J; Shadbolt, Bruce; Byrne, Don; Stuart-Harris, Robin


    Patients with advanced (incurable) tumours usually experience a diverse burden of symptoms. Although many symptom assessment instruments are available, we examined whether these addressed tumour-related symptoms. We reviewed existing symptom assessment instruments and found a number of deficiencies such as instruments being too long or burdensome, too short, or measuring quality of life rather than tumour-related symptoms. Others focused on emotional, rather than physical symptoms. Therefore, we decided to devise a new symptom instrument. A list of 20 symptoms common in patients with advanced tumours generated from the literature and existing instruments, was ranked according to prevalence by 202 Australian clinicians. Following clinicians' responses, the list was revised and two severity assessment scales (functional severity and distress severity) added. The resultant 18-item list was assessed in 44 outpatients with advanced tumours. Patient responses indicated that a shorter questionnaire of 11 items, reflecting three main symptom clusters, provided a good representation of physical symptoms. An additional symptom that is an important predictor of survival was added, making a 12-item questionnaire, which was entitled 'The Canberra Symptom Scorecard' (CSS). For symptom severity, the distress severity scale was more appropriate than the functional severity scale. The CSS focuses on tumour-related physical symptoms. It is about to be assessed in patients with advanced tumours receiving palliative treatments, when it will also be validated against existing instruments

  17. Social phobia symptoms: prevalence, sociodemographic correlates, and overlap with specific phobia symptoms.

    Iancu, Iulian; Levin, Jennifer; Hermesh, Haggai; Dannon, Pinhas; Poreh, Amir; Ben-Yehuda, Yoram; Kaplan, Zeev; Marom, Sofi; Kotler, Moshe


    Social phobia (SP) is a highly prevalent disorder in Western countries, but is rather rare in Eastern societies. Prevalence rates range from 0.5% in Eastern samples up to 16% in Western studies. Its prevalence in Israel, an Asian state characterized by Western culture, has not yet been studied. The present study aimed to assess the prevalence of SP symptoms in a nonclinical sample of Israeli adolescents, to characterize sociodemographic correlates of SP symptoms and to evaluate comorbidity with specific phobia symptoms. Participants included 850 young soldiers from the Israel Defense Forces. Measures included the Liebowitz Social Anxiety Scale (LSAS; self-report version), a questionnaire on specific fears and phobias, and a sociodemographic questionnaire. Clinical and demographic correlates of SP were also examined. Probable SP (LSAS >or=80) was present in 4.5% of the sample. Overall, SP symptoms were reported by a great percentage of the subjects, as displayed by the rather high mean LSAS scores (29; SD = 23.79) in this nonclinical sample. The following variables were accompanied by higher LSAS scores according to our regression model: inability to perform command activities, receiving psychotropic medication before army service, having less than two friends, shy family members, and treatment during military service. Subjects with probable SP had a rate of comorbidity with specific phobia symptoms of 44%. Our findings corroborate those from other studies in Western countries, both regarding the high prevalence of SP symptoms and its demographic and clinical correlates, as well as regarding the high overlap rate with specific phobia symptoms.

  18. Symptom appraisal, help seeking, and lay consultancy for symptoms of head and neck cancer.

    Queenan, J A; Gottlieb, B H; Feldman-Stewart, D; Hall, S F; Irish, J; Groome, P A


    Early diagnosis is important in head and neck cancer (HNC) patients to maximize the effectiveness of the treatments and minimize the debilitation associated with both the cancer and the invasive treatments of advanced disease. Many patients present with advanced disease, and there is little understanding as to why. This study investigated patients' symptom appraisal, help seeking, and lay consultancy up to the time they first went to see a health care professional (HCP). We interviewed 83 patients diagnosed with HNC. The study design was cross sectional and consisted of structured telephone interviews and a medical chart review. We gathered information on the participant's personal reactions to their symptoms, characteristics of their social network, and the feedback they received. We found that 18% of the participants thought that their symptoms were urgent enough to warrant further investigation. Participants rarely (6%) attributed their symptoms to cancer. Eighty-nine percent reported that they were unaware of the early warning signs and symptoms of HNC. Fifty-seven percent of the participants disclosed their symptoms to at least one lay consultant before seeking help from an HCP. The lay consultants were usually their spouse (77%), and the most common advice they offered was to see a doctor (76%). Lastly, 81% of the participants report that their spouse influenced their decision to see an HCP. The results of this study suggest that patients frequently believe that their symptoms were nonurgent and that their lay consultants influence their decision to seek help from an HCP.

    Wytiaz, Victoria; Homko, Carol; Duffy, Frank; Schey, Ron; Parkman, Henry P


    Nutritional counseling for gastroparesis focuses on reduction of meal size, fiber, and fat to control symptoms. The tolerance of gastroparesis patients for particular foods is largely anecdotal. The aim of this study was to identify and characterize foods provoking or alleviating gastroparesis symptoms. Gastroparesis patients completed: (1) Demographic Questionnaire; (2) Patient Assessment of Upper GI Symptoms; (3) Food Toleration and Aversion survey asking patients about experiences when eating certain foods utilizing a scale from -3 (greatly worsening symptoms) to +3 (greatly improving symptoms). Descriptive qualities (acidic, fatty, spicy, roughage-based, bitter, salty, bland, and sweet) were assigned to foods. Forty-five gastroparesis patients participated (39 idiopathic gastroparesis). Foods worsening symptoms included: orange juice, fried chicken, cabbage, oranges, sausage, pizza, peppers, onions, tomato juice, lettuce, coffee, salsa, broccoli, bacon, and roast beef. Saltine crackers, jello, and graham crackers moderately improved symptoms. Twelve additional foods were tolerated by patients (not provoking symptoms): ginger ale, gluten-free foods, tea, sweet potatoes, pretzels, white fish, clear soup, salmon, potatoes, white rice, popsicles, and applesauce. Foods provoking symptoms were generally fatty, acidic, spicy, and roughage-based. The foods shown to be tolerable were generally bland, sweet, salty, and starchy. This study identified specific foods that worsen as well as foods that may help alleviate symptoms of gastroparesis. Foods that provoked symptoms differed in quality from foods that alleviated symptoms or were tolerable. The results of this study illustrate specific examples of foods that aggravate or improve symptoms and provide suggestions for a gastroparesis diet.

  20. Symptom Characteristics and Medical History of an Online Sample of Women Who Experience Symptoms of Persistent Genital Arousal.

    Jackowich, Robyn; Pink, Leah; Gordon, Allan; Poirier, Évéline; Pukall, Caroline F


    Persistent genital arousal disorder (PGAD; Leiblum & Nathan, 2001 ) is characterized by distressing symptoms suggestive of genital arousal in the absence of subjective feelings of arousal. Although awareness of PGAD is growing, there continues to be a lack of systematic research on it. This study characterized an online sample of women with symptoms of persistent genital arousal (PGA) in terms of their symptom characteristics, medical comorbidities, symptom triggers, management strategies, and predictors of distress. Women reported diverse PGA symptoms, with almost half reporting painful symptoms, and most reported very high distress and negative emotions. Further research and awareness of PGA are needed to provide effective care for this population.

  9. Testing specificity among parents' depressive symptoms, parenting, and child internalizing and externalizing symptoms.

    Gruhn, Meredith A; Dunbar, Jennifer P; Watson, Kelly H; Reising, Michelle M; McKee, Laura; Forehand, Rex; Cole, David A; Compas, Bruce E


    The present study examined the specificity in relations between observed withdrawn and intrusive parenting behaviors and children's internalizing and externalizing symptoms in an at-risk sample of children (ages 9 to 15 years old) of parents with a history of depression (N = 180). Given past findings that parental depression and parenting behaviors may differentially impact boys and girls, gender was examined as a moderator of the relations between these factors and child adjustment. Correlation and linear regression analyses showed that parental depressive symptoms were significantly related to withdrawn parenting for parents of boys and girls and to intrusive parenting for parents of boys only. When controlling for intrusive parenting, preliminary analyses demonstrated that parental depressive symptoms were significantly related to withdrawn parenting for parents of boys, and this association approached significance for parents of girls. Specificity analyses yielded that, when controlling for the other type of problem (i.e., internalizing or externalizing), withdrawn parenting specifically predicted externalizing problems but not internalizing problems in girls. No evidence of specificity was found for boys in this sample, suggesting that impaired parenting behaviors are diffusely related to both internalizing and externalizing symptoms for boys. Overall, results highlight the importance of accounting for child gender and suggest that targeting improvement in parenting behaviors and the reduction of depressive symptoms in interventions with parents with a history of depression may have potential to reduce internalizing and externalizing problems in this high-risk population.

    Farrell-Carnahan, Leah; Barnett, Scott; Lamberty, Gregory; Hammond, Flora M; Kretzmer, Tracy S; Franke, Laura M; Geiss, Meghan; Howe, Laura; Nakase-Richardson, Risa


    Insomnia and behavioural health symptoms 1 year after traumatic brain injury (TBI) were examined in a clinical sample representative of veterans who received inpatient treatment for TBI-related issues within the Veterans Health Administration. This was a cross-sectional sub-study (n = 112) of the Polytrauma Rehabilitation Centres' traumatic brain injury model system programme. Prevalence estimates of insomnia, depression, general anxiety, nightmares, headache and substance use, stratified by injury severity, were derived. Univariate logistic regression was used to examine unadjusted effects for each behavioural health problem and insomnia by injury severity. Participants were primarily male, insomnia; those with mild TBI were significantly more likely to meet criteria (43%) than those with moderate/severe TBI (22%), χ(2)(1, n = 112) = 5.088, p ≤ 0.05. Univariable logistic regression analyses revealed depressive symptoms and general anxiety were significantly associated with insomnia symptoms after TBI of any severity. Headache and binge drinking were significantly inversely related to insomnia symptoms after moderate/severe TBI, but not MTBI. Veterans with history of TBI, of any severity, and current insomnia symptoms may be at increased risk for depression and anxiety 1 year after TBI.

  13. The role of stress in IBS symptom severity

    Sanda Pletikosic


    Full Text Available Irritable bowel syndrome is regarded as a biopsychosocial disorder, the result of a complex combination of predisposing, precipitating and perpetuating factors. Personality traits, affective status and stress are some of the relevant factors contributing to lower quality of life and symptom exacerbation in IBS patients. In order to examine the role of stress in IBS symptom exacerbation, the aims of this study were to explore the relationship of daily stressful events and symptom severity in a prospective manner and to explore the roles of neuroticism, anxiety, depression and stress in the vicious circle of symptom perpetuation. A total of 49 patients with IBS reported their symptom severity and daily stressful events intensity each day for 14 consecutive days. They also completed the Big five personality inventory, the Beck Depression Inventory and the State-trait anxiety inventory. Cross-correlation analyses were performed on the time series data for daily stress and symptom severity for each participant separately. Four different patterns of relationships were found in different subgroups of participants: positive cross-correlations of symptom severity and stress intensity on the same day; higher symptom severity on days following stressful days; lower symptom severity on days following stressful days; and lower stress intensity on days following severe symptoms. Using average scores for daily stress and symptom severity, as well as scores for neuroticism, anxiety and depression, we performed a path analysis to test a model of symptom exacerbation. It showed that, on the group level, average stress intensity predicts average symptom severity. Neuroticism and anxiety were not significant predictors of symptom severity, while depression showed a marginally significant relationship with symptom severity, mediated by stress intensity. In conclusion, depression and daily stress seem to be important contributors to the vicious circle of IBS symptom

  14. On counterbalancing of symptom-reporting in trauma surveys.

    Reddy, Madhavi K; Polusny, Melissa A; Murdoch, Maureen


    Some traumatic stress research surveys are potentially subject to context effects, such as priming, because they include questions about traumatic experiences and trauma-related symptoms within the same survey. In this study, asking about traumatic experiences before or after asking about PTSD influenced symptom reporting was investigated in a sample of 424 National Guard soldiers. Results indicate ordering of symptom measures immediately before or after reports of combat experiences did not influence reports of PTSD symptoms. Implications of results are discussed.

  15. What is a homoeopathic symptom, in daily practice and research?

    Lex Rutten; K C Muraleedharan; Vaishali H Shinde; Raj K Manchanda


    Background: For two centuries, homoeopathic practitioners are using personal characteristics, symptoms, and diagnoses/conditions to compare the “patient picture” with the “medicine picture.” All data are considered within the context of the totality, using a so-called heuristic strategy. In prognostic factor research analyzing homoeopathic symptoms, we cannot use this context. Question: What is the essence of a homoeopathic symptom and how do we make assessment of homoeopathic symptoms applic...

  16. Cold stress induces lower urinary tract symptoms.

    Imamura, Tetsuya; Ishizuka, Osamu; Nishizawa, Osamu


    Cold stress as a result of whole-body cooling at low environmental temperatures exacerbates lower urinary tract symptoms, such as urinary urgency, nocturia and residual urine. We established a model system using healthy conscious rats to explore the mechanisms of cold stress-induced detrusor overactivity. In this review, we summarize the basic findings shown by this model. Rats that were quickly transferred from room temperature (27 ± 2°C) to low temperature (4 ± 2°C) showed detrusor overactivity including increased basal pressure and decreased voiding interval, micturition volume, and bladder capacity. The cold stress-induced detrusor overactivity is mediated through a resiniferatoxin-sensitve C-fiber sensory nerve pathway involving α1-adrenergic receptors. Transient receptor potential melastatin 8 channels, which are sensitive to thermal changes below 25-28°C, also play an important role in mediating the cold stress responses. Additionally, the sympathetic nervous system is associated with transient hypertension and decreases of skin surface temperature that are closely correlated with the detrusor overactivity. With this cold stress model, we showed that α1-adrenergic receptor antagonists have the potential to treat cold stress-exacerbated lower urinary tract symptoms. In addition, we showed that traditional Japanese herbal mixtures composed of Hachimijiogan act, in part, by increasing skin temperature and reducing the number of cold sensitive transient receptor potential melastatin channels in the skin. The effects of herbal mixtures have the potential to treat and/or prevent the exacerbation of lower urinary tract symptoms by providing resistance to the cold stress responses. Our model provides new opportunities for utilizing animal disease models with altered lower urinary tract functions to explore the effects of novel therapeutic drugs. © 2013 The Japanese Urological Association.

  17. Transvestism as a Symptom: A Case Series.

    Anupama, M; Gangadhar, K H; Shetty, Vandana B; Dip, P Bhadja


    Transvestism, commonly termed as cross-dressing, means to dress in the clothing of opposite sex. We describe a series of three cases with transvestism as one of their primary complaints. The discussion sheds light on the various ways in which transvestism as a symptom can present in Psychiatry. In the first two cases, there was lower intelligence. In first and third case, there were other paraphilia along with transvestism. Second case had co-morbid obsessive-compulsive disorder (OCD) and had good response to selective serotonin reuptake inhibitor (SSRI).

  20. [Symptoms diagnosis and treatment of dyscalulia].

    Ise, Elena; Schulte-Körne, Gerd


    Children with dyscalculia show deficits in basic numerical processing which cause difficulties in the acquisition of mathematical skills. This article provides an overview of current research findings regarding the symptoms, cause, and prognosis of dyscalculia, and it summarizes recent developments in the diagnosis, early intervention, and treatment thereof. Diagnosis has improved recently because newly developed tests focus not only on the math curriculum, but also on basic skills found to be impaired in dyscalculia. A controversial debate continues with regard to IQ achievement discrepancy. International studies have demonstrated the effectiveness of specialized interventions. This article summarizes the research findings from intervention studies, describes different treatment approaches, and discusses implications for clinical practice.
