    To demonstrate the efficiency of vitrifying mature human oocytes for different clinical indications. Descriptive case series. Cryobiology laboratory, Centro Colombiano de Fertilidad y Esterilidad-CECOLFES LTDA. (Bogotá, Colombia). Oocyte vitrification was offered as an alternative management for patients undergoing infertility treatment because of ovarian hyperstimulation syndrome, premature ovarian failure, natural ovarian failure, male factor, poor response, or oocyte donation. Mature oocytes were obtained from 33 donor women and 40 patients undergoing infertility treatment. Oocytes were retrieved by ultrasound-guided transvaginal aspiration and vitrified with the Cryotops method, with 30% ethylene glycol, 30% dimethyl sulfoxide, and 0.5 mol/L sucrose. Viability was assessed 3 hours after thawing. The surviving oocytes were inseminated by intracytoplasmic sperm injection. Fertilization was evaluated after 24 hours. The zygotes were further cultured in vitro for up to 72 hours until time of embryo transfer. Recovery, viability, fertilization, and pregnancy rates. Oocyte vitrification with the Cryotop method resulted in high rates of recovery, viability, fertilization, cleavage, and ongoing pregnancy. Vitrification with the Cryotop method is an efficient, fast, and economical method for oocyte cryopreservation that offers high rates of survival, fertilization, embryo development, and ongoing normal pregnancies, providing a new alternative for the management of female infertility.

    Not all euploid embryos implant, necessitating additional tools to select viable blastocysts in preimplantation genetic screening cycles. In this retrospective cohort study, 129 consecutive patients who underwent 129 single euploid blastocyst transfers in cryopreserved embryo transfer cycles were included. All embryos were individually cultured in a time-lapse incubator from intracytoplasmic sperm injection up to trophoectoderm biopsy. Twenty-three time-lapse morphokinetic variables were tested among patients with (n = 68) or without (n = 61) ongoing pregnancy. All 23 time-lapse morphokinetic variables, apart from duration of blastulation (tB-tSB), were comparable between patients with or without ongoing pregnancy. Duration of blastulation was significantly shorter in patients with ongoing pregnancy (8.1 ± 3.2 versus 9.5 ± 3.4 h; P = 0.014); shorter duration of blastulation remained an independent predictor for ongoing pregnancy, when tested by logistic regression analysis (OR 0.81; 95% CI 0.70 to 0.93). One important limitation of this study, and a reason for caution, is the use of multiple comparisons, which can lead to differences at the 0.05 level simply by chance or random variation. Nonetheless, the study suggests that when more than one euploid blastocyst is available, priority might be given to those with a shorter duration of blastulation.

    To estimate cumulative maternal morbidity among women who delivered at term in their first pregnancy on the basis of type of labour in the first pregnancy. Using a 25-year population-based cohort (1988 to 2012) derived from the Nova Scotia Atlee Perinatal Database, we determined the type of labour in successive pregnancies in low-risk, nulliparous women at term in their first pregnancy (who had at least one subsequent pregnancy), and the maternal outcomes in subsequent deliveries based on the type of labour in the first pregnancy. A total of 36 871 pregnancies satisfied inclusion and exclusion criteria, 1346 of which were delivered by Caesarean section without labour in the first pregnancy. Rates of most adverse maternal outcomes were low (≤1%). The type of labour in the first pregnancy influenced the subsequent risk of postpartum hemorrhage and blood transfusion, and the risks increased with successive deliveries when labours were spontaneous in onset or were induced. The risks for abnormal placentation were low with subsequent deliveries, including following CS without labour in the first pregnancy, and risks for overall severe maternal morbidity were less than 10% for all subsequent deliveries. The absolute risks for severe maternal morbidity outcomes in a population of women without a high number of subsequent pregnancies were small (regardless of type of labour in the first pregnancy); this provides important information for women, families, and caregivers when considering pregnancy outcomes related to type of labour.

    To characterize prednisone use in pregnant women with rheumatoid arthritis using individual-level heat-maps and clustering individual trajectories of prednisone dose, and to evaluate the association between prednisone dose trajectory groups and gestational length. This study included pregnant women with rheumatoid arthritis who enrolled in the MotherToBaby Autoimmune Diseases in Pregnancy Study (2003-2014) before gestational week 20 and reported prednisone use without another oral glucocorticoid during pregnancy (n = 254). Information on medication use and pregnancy outcomes was collected by telephone interview plus by medical record review. Prednisone daily dose and cumulative dose were plotted by gestational day using a heat map for each individual. K-means clustering was used to cluster individual trajectories of prednisone dose into groups. The associations between trajectory group and demographics, disease severity measured by the Health Assessment Questionnaire at enrollment, and gestational length were evaluated. Women used prednisone 3 to 292 days during pregnancy, with daily doses ranging from <1 to 60 mg. Total cumulative dose ranged from 8 to 6225 mg. Disease severity, non-biologic disease modifying anti-rheumatic drug use, and gestational length varied significantly by trajectory group. After adjusting for disease severity, non-biologic disease modifying anti-rheumatic drug use, and other covariates, the highest vs lowest daily dose trajectory group was associated with reduced gestational age at delivery (β: -2.3 weeks (95%: -3.4, -1.3)), as was the highest vs lowest cumulative dose trajectory group (β: -2.6 weeks (95%: -3.6, -1.5)). In pregnant women with rheumatoid arthritis, patterns of higher prednisone dose were associated with shorter gestational length compared with lower dose. Copyright © 2018 John Wiley & Sons, Ltd.

    Cumulative effects analysis (CEA) allows natural resource managers to understand the status of resources in historical context, learn from past management actions, and adapt future activities accordingly. U.S. federal agencies are required to complete CEA as part of environmental impact assessment under the National Environmental Policy Act (NEPA). Past research on CEA as part of NEPA has identified significant deficiencies in CEA practice, suggested methodologies for handling difficult aspects of CEA, and analyzed the rise in litigation over CEA in U.S. courts. This article provides a review of the literature and legal standards related to CEA as it is done under NEPA and then examines current practice on a U.S. National Forest, utilizing qualitative methods in order to provide a detailed understanding of current approaches to CEA. Research objectives were to understand current practice, investigate ongoing challenges, and identify impediments to improvement. Methods included a systematic review of a set of NEPA documents and semi-structured interviews with practitioners, scientists, and members of the public. Findings indicate that the primary challenges associated with CEA include: issues of both geographic and temporal scale of analysis, confusion over the purpose of the requirement, the lack of monitoring data, and problems coordinating and disseminating data. Improved monitoring strategies and programmatic analyses could support improved CEA practice.

    The aim of this study is to evaluate the correlation between serum estradiol (E 2 ) levels during artificial autologous frozen embryo transfer (FET) cycles and ongoing pregnancy/live birth rates (OP/LB). A historical cohort study was conducted in an academic setting in order to correlate peak and average estradiol levels with ongoing pregnancy/live birth rates for all autologous artificial frozen embryo transfer cycles performed from 1/2011 to 12/2014. Average and peak E 2 levels from 110 autologous artificial FET cycles from 95 patients were analyzed. Average E 2 levels were significantly lower in cycles resulting in OP/LB compared to those that did not (234.1 ± 16.6 pg/ml vs. 315 ± 24.8 pg/ml, respectively, p = 0.04). Although peak E 2 levels were not significantly different between cycles resulting in OP/LB compared with those that did not (366.9 ± 27.7 pg/ml vs. 459.1 ± 32.3 pg/ml, respectively, p = 0.19), correlation analysis revealed a statistically significant (p = 0.02) downward trend in OP/LB rates with increasing peak E 2 levels. This study suggests that elevated E 2 levels in artificial autologous FET cycles are associated with lower OP/LB rates. Estradiol levels should be monitored during artificial FET cycles.

    Polycystic ovary syndrome (PCOS) is a heterogeneous syndrome. In vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) is required for PCOS cases that are refractory to standard ovulation induction or have co-existing infertility factors in women with PCOS and Tubal factor subfertility. Assess ethnic variations in response to IVF/ICSI treatment. Observational Comparative study in a University hospital fertility clinic in women with PCOS and Tubal factor subfertility. Women with PCOS (Asians: AP=104; Caucasians: CP=220) and those with tubal factor infertility seeking fertility treatment were assessed (Asians: AC=84; Caucasians: CC=200). Six hundred and eight fresh IVF or ICSI cycles using long protocol of GnRHa suppression and resulting in a fresh embryo transfer were compared. The primary endpoint was to assess the dose of gonadotropins used in the cycles. The secondary outcomes were: total number of oocytes retrieved, fertilization and ongoing clinical pregnancy rates. We found that the South Asian women presented at a younger age for the management of sub-fertility. An extended stimulation phase and Caucasian ethnicity showed an inverse correlation with the number of oocytes retrieved in the PCOS subgroup. Caucasian ethnicity was associated with a higher fertilization rate however increase in body mass index (BMI) and the laboratory technique of IVF appeared to have a negative impact on fertilization rates in the PCOS subgroup. Commencing down regulation on day 1 of the cycles was negatively associated with fertilization rates in the tubal group. In terms of clinical pregnancy rates, the Caucasian PCOS had a 2.5 times (95% CI: 1.25-5) higher chance of an ongoing clinical pregnancy as compared with their Asian counterpart. Also, a unit increase in the basal FSH concentration reduced the odds of pregnancy by 18.6% (95% CI: 1.8-32.6%) in the PCOS group. The Asian PCOS have a greater sensitivity to gonadotropin stimulation with lower fertilization and

    Classical within-subject analysis in functional magnetic resonance imaging (fMRI) relies on a detection step to localize which parts of the brain are activated by a given stimulus type. This is usually achieved using model-based approaches. Here, we propose an alternative exploratory analysis. The originality of this contribution is twofold. First, we propose a synthetic, consistent, and comparative overview of the various stochastic processes and estimation procedures used to model and analyze scale invariance. Notably, it is explained how multifractal models are more versatile to adjust the scaling properties of fMRI data but require more elaborated analysis procedures. Second, we bring evidence of the existence of actual scaling in fMRI time series that are clearly disentangled from putative superimposed non-stationarities. By nature, scaling analysis requires the use of long enough signals with high frequency sampling rate. To this end, we make use of a localized 3-D echo volume imaging (EVI) technique, which has recently emerged in fMRI because it allows very fast acquisitions of successive brain volumes. High temporal resolution EVI fMRI data have been acquired both in resting state and during a slow event-related visual paradigm. A voxel-based systematic multifractal analysis has been performed over both kinds of data. Combining multifractal attribute estimates together with paired statistical tests, we observe significant scaling parameter changes between ongoing and evoked brain activity, which clearly validate an increase in long memory and suggest a global multi-fractality decrease effect under activation.

    Early during human development, the trophoblast lineage differentiates to commence placentation. Where the placenta contacts the uterine decidua, extravillous trophoblast (EVT) cells differentiate and invade maternal tissues. EVT cells, identified by expression of HLA-G, invade into uterine blood vessels (endovascular EVT), as well as glands (endoglandular EVT), and open such luminal structures towards the intervillous space of the placenta. Endoglandular invasion diverts the contents of uterine glands to the intervillous space, while glands near the margin of the placenta that also contain endoglandular EVT cells open into the reproductive tract. Cells of the trophoblast lineage have thus been recovered from the uterine cavity and endocervical canal. An emerging non-invasive technology [trophoblast retrieval and isolation from the cervix (TRIC)] isolates and examines EVT cells residing in the cervix to explore their origin, biology and relationship to pregnancy and fetal status. This review explores the origins and possible uses of trophoblast cells obtained during ongoing pregnancies (weeks 5-20) by TRIC. We hypothesize that endoglandular EVT cells at the margins of the expanding placenta enter the uterine cavity and are carried together with uterine secretion products to the cervix where they can be retrieved from a Papanicolaou (Pap) smear. The advantages of TRIC for investigation of human placentation and prenatal testing will be considered. Evidence from the literature, and from archived in utero placental histological sections, is presented to support these hypotheses. We used 52 out of 80 publications that appeared between 1966 and 2017 and were found by searching the PubMed and Google Scholar databases. The studies described trophoblast invasion of uterine vessels and glands, as well as trophoblast cells residing in the reproductive tract. This was supplemented with literature on human placental health and disease. The literature describes a variety of

The Medical Outcomes Study Short-form 36 Health Survey (SF-36) measured the health-related quality of life. the prevalence rate of intimate partner abuse during pregnancy was 134 out of 1200 (11.2%, 95% confidence interval [CI] 9.4-13.0%). They consisted of an only psychologically abused group (32.1%, 95% CI 24.2-40.0%), an only physically abused group (20.9%, 95% CI 14.0-27.8%), and a combined psychological and physically abused group (47.0%, 95% CI 38.5-55.5%). Over half of the women (53.0%, 95% CI 44.5-61.5%) experienced more than one type of abuse. Women who had experienced different types of intimate partner abuse were associated with lower scores in the majority of domains and the subscales of the SF-36 (pquality of life of the women. the problem of intimate partner abuse during pregnancy is similar to most Western countries, and the negative effect of different types of such abuse on the health-related quality of life over time seems to be cumulative. the relatively poor health-related quality of life of the abused women highlights the necessity of developing a checklist or a structured questionnaire that will assist in the detection of different types and combinations of intimate partner abuse, and that will be helpful in the development of more effective preventive interventions or programmes.

    Full Text Available Abstract Background The UK Collaborative HIV Cohort (UK CHIC is an observational study that collates data on HIV-positive adults accessing HIV clinical care at (currently 13 large clinics in the UK but does not collect pregnancy specific data. The National Study of HIV in Pregnancy and Childhood (NSHPC collates data on HIV-positive women receiving antenatal care from every maternity unit in the UK and Ireland. Both studies collate pseudonymised data and neither dataset contains unique patient identifiers. A methodology was developed to find and match records for women reported to both studies thereby obtaining clinical and treatment data on pregnant HIV-positive women not available from either dataset alone. Results Women in UK CHIC receiving HIV-clinical care in 1996–2009, were found in the NSHPC dataset by initially ‘linking’ records with identical date-of-birth, linked records were then accepted as a genuine ‘match’, if they had further matching fields including CD4 test date. In total, 2063 women were found in both datasets, representing 23.1% of HIV-positive women with a pregnancy in the UK (n = 8932. Clinical data was available in UK CHIC following most pregnancies (92.0%, 2471/2685 pregnancies starting before 2009. There was bias towards matching women with repeat pregnancies (35.9% (741/2063 of women found in both datasets had a repeat pregnancy compared to 21.9% (1502/6869 of women in NSHPC only and matching women HIV diagnosed before their first reported pregnancy (54.8% (1131/2063 compared to 47.7% (3278/6869, respectively. Conclusions Through the use of demographic data and clinical dates, records from two independent studies were successfully matched, providing data not available from either study alone.

    The objective of the present study was to determine the effect of resynchronization on Day 23 with either GnRH or P4 (controlled internal drug release device containing progesterone; CIDR) on pregnancy rate, cumulative pregnancy, and embryonic and fetal losses in CIDR-GnRH synchronized Nili-Ravi buffaloes. Buffaloes (n = 181) of mixed parity, lactating, 181 ± 73 days postpartum, a body condition score (BCS) of 3.2 ± 0.5 (scale of 1-5), and 450-600 kg weight were subjected to synchronization and resynchronization. All buffaloes received CIDR on Day -9.5. In addition, GnRH was injected 36 h after CIDR removal, and timed artificial insemination (TAI) was performed 18 h later (Day 0). On Day 23, buffaloes were randomly assigned to receive one of the following treatments: 1) CON (n = 63), 2) P4 (n = 55), and 3) GnRH (n = 63) for resynchronization (2nd AI). Pregnancy rate, and embryonic and fetal losses were monitored by serial ultrasonography on Days 30, 45, 60, and 90 after synchronization (1st TAI), respectively. The pregnancy rate in GnRH-treated buffaloes remained significantly and consistently higher (P  0.05) between the OVS and CIDR groups; whereas the, cumulative pregnancy rate in GnRH + OVS buffaloes (81%) after 1st and 2 nd AI when determined on Day 64 was higher (P losses were significantly lower (P losses were fewer and did not differ (P > 0.05) due to treatments on Day 60 or 90 post 1st AI. In conclusion, 1) the pregnancy rate and cumulative pregnancy rate in GnRH-treated buffaloes were higher than in CON buffaloes on Day 64 after synchronization and resynchronization, and 2) embryonic and fetal losses were lower in GnRH-treated buffaloes than in CON buffaloes when determined from Day 31-90 post 1st TAI.

  4. CUMBIN - CUMULATIVE BINOMIAL PROGRAMS

    Science.gov (United States)

    Bowerman, P. N.

    1994-01-01

    The cumulative binomial program, CUMBIN, is one of a set of three programs which calculate cumulative binomial probability distributions for arbitrary inputs. The three programs, CUMBIN, NEWTONP (NPO-17556), and CROSSER (NPO-17557), can be used independently of one another. CUMBIN can be used by statisticians and users of statistical procedures, test planners, designers, and numerical analysts. The program has been used for reliability/availability calculations. CUMBIN calculates the probability that a system of n components has at least k operating if the probability that any one operating is p and the components are independent. Equivalently, this is the reliability of a k-out-of-n system having independent components with common reliability p. CUMBIN can evaluate the incomplete beta distribution for two positive integer arguments. CUMBIN can also evaluate the cumulative F distribution and the negative binomial distribution, and can determine the sample size in a test design. CUMBIN is designed to work well with all integer values 0 < k <= n. To run the program, the user simply runs the executable version and inputs the information requested by the program. The program is not designed to weed out incorrect inputs, so the user must take care to make sure the inputs are correct. Once all input has been entered, the program calculates and lists the result. The CUMBIN program is written in C. It was developed on an IBM AT with a numeric co-processor using Microsoft C 5.0.

    Limit fragmentation of light nuclei (deuterium, helium) bombarded with 8,6 GeV/c protons was investigated. Fragments (pions, protons and deuterons) were detected within the emission angle 50-150 deg with regard to primary protons and within the pulse range 150-180 MeV/c. By the kinematics of collision of a primary proton with a target at rest the fragments observed correspond to a target mass upto 3 GeV. Thus, the data obtained correspond to teh cumulation upto the third order

    The cumulative binomial program, CROSSER, is one of a set of three programs which calculate cumulative binomial probability distributions for arbitrary inputs. The three programs, CROSSER, CUMBIN (NPO-17555), and NEWTONP (NPO-17556), can be used independently of one another. CROSSER can be used by statisticians and users of statistical procedures, test planners, designers, and numerical analysts. The program has been used for reliability/availability calculations. CROSSER calculates the point at which the reliability of a k-out-of-n system equals the common reliability of the n components. It is designed to work well with all integer values 0 < k <= n. To run the program, the user simply runs the executable version and inputs the information requested by the program. The program is not designed to weed out incorrect inputs, so the user must take care to make sure the inputs are correct. Once all input has been entered, the program calculates and lists the result. It also lists the number of iterations of Newton's method required to calculate the answer within the given error. The CROSSER program is written in C. It was developed on an IBM AT with a numeric co-processor using Microsoft C 5.0. Because the source code is written using standard C structures and functions, it should compile correctly with most C compilers. The program format is interactive. It has been implemented under DOS 3.2 and has a memory requirement of 26K. CROSSER was developed in 1988.

    Analyze the cumulative evidence for pregnancy outcomes after maternal exposure to tocilizumab, an anti-interleukin-6-receptor monoclonal antibody used for the treatment of rheumatoid arthritis and juvenile idiopathic arthritis. At present, published experience on tocilizumab use during pregnancy is very limited. We have analyzed all pregnancy-related reports documented in the Roche Global Safety Database until December 31, 2014 (n = 501). After exclusion of ongoing pregnancies, duplicates, and cases retrieved from the literature, 399 women were found to have been exposed to tocilizumab shortly before or during pregnancy, with pregnancy outcomes being reported in 288 pregnancies (72.2%). Of these 288 pregnancies, 180 were prospectively reported resulting in 109 live births (60.6%), 39 spontaneous abortions (21.7%), 31 elective terminations of pregnancy (17.2%), and 1 stillbirth. The rate of malformations was 4.5%. Co-medications included methotrexate in 21.1% of the prospectively ascertained cases. Compared to the general population, an increased rate of preterm birth (31.2%) was observed. Retrospectively reported pregnancies (n = 108) resulted in 55 live births (50.9%), 31 spontaneous abortions (28.7%), and 22 elective terminations (20.4%). Three infants/fetuses with congenital anomalies were reported in this group. No increased risks for adverse pregnancy outcomes were observed after paternal exposure in 13 pregnancies with known outcome. No indication for a substantially increased malformation risk was observed. Considering the limitations of global safety databases, the data do not yet prove safety, but provide information for physicians and patients to make informed decisions. This is particularly important after inadvertent exposure to tocilizumab, shortly before or during early pregnancy. Copyright © 2016 Elsevier Inc. All rights reserved.

NEWTONP can be used by statisticians and users of statistical procedures, test planners, designers, and numerical analysts. The program has been used for reliability/availability calculations. NEWTONP calculates the probably p required to yield a given system reliability V for a k-out-of-n system. It can also be used to determine the Clopper-Pearson confidence limits (either one-sided or two-sided) for the parameter p of a Bernoulli distribution. NEWTONP can determine Bayesian probability limits for a proportion (if the beta prior has positive integer parameters). It can determine the percentiles of incomplete beta distributions with positive integer parameters. It can also determine the percentiles of F distributions and the midian plotting positions in probability plotting. NEWTONP is designed to work well with all integer values 0 < k <= n. To run the program, the user simply runs the executable version and inputs the information requested by the program. NEWTONP is not designed to weed out incorrect inputs, so the user must take care to make sure the inputs are correct. Once all input has been entered, the program calculates and lists the result.

  14. Cumulative radiation effect

    Kirk, J.; Gray, W.M.; Watson, E.R.

    1977-01-01

    In five previous papers, the concept of Cumulative Radiation Effect (CRE) has been presented as a scale of accumulative sub-tolerance radiation damage, with a unique value of the CRE describing a specific level of radiation effect. Simple nomographic and tabular methods for the solution of practical problems in radiotherapy are now described. An essential feature of solving a CRE problem is firstly to present it in a concise and readily appreciated form, and, to do this, nomenclature has been introduced to describe schedules and regimes as compactly as possible. Simple algebraic equations have been derived to describe the CRE achieved by multi-schedule regimes. In these equations, the equivalence conditions existing at the junctions between schedules are not explicit and the equations are based on the CREs of the constituent schedules assessed individually without reference to their context in the regime as a whole. This independent evaluation of CREs for each schedule has resulted in a considerable simplification in the calculation of complex problems. The calculations are further simplified by the use of suitable tables and nomograms, so that the mathematics involved is reduced to simple arithmetical operations which require at the most the use of a slide rule but can be done by hand. The order of procedure in the presentation and calculation of CRE problems can be summarised in an evaluation procedure sheet. The resulting simple methods for solving practical problems of any complexity on the CRE-system are demonstrated by a number of examples. (author)

    Cumulative Radiation Effect (CRE) represents a scale of accumulative sub-tolerance radiation damage, with a unique value of the CRE describing a specific level of radiation effect. Computer calculations have been used to simplify the evaluation of problems associated with the applications of the CRE-system in radiotherapy. In a general appraisal of the applications of computers to the CRE-system, the various problems encountered in clinical radiotherapy have been categorised into those involving the evaluation of a CRE at a point in tissue and those involving the calculation of CRE distributions. As a general guide, the computer techniques adopted at the Glasgow Institute of Radiotherapeutics for the solution of CRE problems are presented, and consist basically of a package of three interactive programs for point CRE calculations and a Fortran program which calculates CRE distributions for iso-effect treatment planning. Many examples are given to demonstrate the applications of these programs, and special emphasis has been laid on the problem of treating a point in tissue with different doses per fraction on alternate treatment days. The wide range of possible clinical applications of the CRE-system has been outlined and described under the categories of routine clinical applications, retrospective and prospective surveys of patient treatment, and experimental and theoretical research. Some of these applications such as the results of surveys and studies of time optimisation of treatment schedules could have far-reaching consequences and lead to significant improvements in treatment and cure rates with the minimum damage to normal tissue.

The selected articles represent very well the diversity of approaches, contexts and objectives that foster and render highly dynamic this area of study. In Europe, several funding programmes like the 7th Framework Programme, the Lifelong Learning Programme and the most recent Horizon 2020 made specific provisions to support Serious Games projects. At the same time, enterprises are recognizing more and more the potential of SG to train and to motivate their workforce and are therefore joining forces with the academy and SG producers to design specific SG. Serious Games became one of the most interesting “places to be” due to its growing scientific and practitioner community. We can say that the motivating and addictive character of games has been successfully transmitted to the research and development of Serious Games.

RESULTS: Among the published RCTs on diabetes and pregnancy, 171 abstracts were retrieved, 64 full texts were reviewed, and 53 were included. Among the ongoing RCTs published in Clinical...

  1. The challenge of cumulative impacts

    2011-07-01

    Full text: As governments pledge to combat climate change, wind turbines are becoming a common feature of terrestrial and marine environments. Although wind power is a renewable energy source and a means of reducing carbon emissions, there is a need to ensure that the wind farms themselves do not damage the environment. There is particular concern over the impacts of wind farms on bird populations, and with increasing numbers of wind farm proposals, the concern focuses on cumulative impacts. Individually, a wind farm, or indeed any activity/action, may have minor effects on the environment, but collectively these may be significant, potentially greater than the sum of the individual parts acting alone. Cumulative impact assessment is a legislative requirement of environmental impact assessment but such assessments are rarely adequate restricting the acquisition of basic knowledge about the cumulative impacts of wind farms on bird populations. Reasons for this are numerous but a recurring theme is the lack of clear definitions and guidance on how to perform cumulative assessments. Here we present a conceptual framework and include illustrative examples to demonstrate how the framework can be used to improve the planning and execution of cumulative impact assessments. The core concept is that explicit definitions of impacts, actions and scales of assessment are required to reduce uncertainty in the process of assessment and improve communication between stake holders. Only when it is clear what has been included within a cumulative assessment, is it possible to make comparisons between developments. Our framework requires improved legislative guidance on the actions to include in assessments, and advice on the appropriate baselines against which to assess impacts. Cumulative impacts are currently considered on restricted scales (spatial and temporal) relating to individual development assessments. We propose that benefits would be gained from elevating cumulative

    To investigate incidence and prevalence of urinary incontinence during pregnancy and associated risk factors. The data collection was conducted as part of the Norwegian Mother and Child Cohort Study at the Norwegian Institute of Public Health. We present questionnaire data about urinary incontinence obtained from 43,279 women (response rate 45%) by week 30. We report data on any incontinence, in addition to type, frequency, and amount of incontinence. Potential risk factors were investigated by logistic regression analyses. The prevalence of incontinence increased from 26% before pregnancy to 58% in week 30. The corresponding figures for nulliparous women were 15% and 48%, and for parous women 35% and 67%. The cumulative incidence was 46%. Stress urinary incontinence was the most common type of incontinence in week 30 of pregnancy, experienced by 31% of nulliparous and 42% of parous women. The majority of pregnant women had leakage less than once per week and droplets only, both before and during pregnancy. Parity was a strong and significant risk factor for incontinence in adjusted analyses both before pregnancy (odds ratio [OR] 2.5, 95% confidence interval [CI] 2.4-2.7 for primiparous and OR 3.3, 95% CI 3.1-3.5 for multiparous women) and during pregnancy (ORs 2.0, 95% CI 1.9-2.1 and 2.1, 95% CI 2.0-2.2, respectively). Age and body mass index were weaker, but still statistically significant, risk factors. The prevalence of urinary incontinence increases substantially during pregnancy. Incontinence both before and during pregnancy seems to be associated with parity, age, and body mass index. II.

    Full Text Available Cumulative risk (CR models provide some of the most robust findings in the developmental literature, predicting numerous and varied outcomes. Typically, however, these outcomes are predicted one at a time, across different samples, using concurrent designs, longitudinal designs of short duration, or retrospective designs. We predicted that a single CR index, applied within a single sample, would prospectively predict diverse outcomes, i.e., depression, intelligence, school dropout, arrest, smoking, and physical disease from childhood to adulthood. Further, we predicted that number of risk factors would predict number of adverse outcomes (cumulative outcome; CO. We also predicted that early CR (assessed at age 5/6 explains variance in CO above and beyond that explained by subsequent risk (assessed at ages 12/13 and 19/20. The sample consisted of 284 individuals, 48% of whom were diagnosed with a speech/language disorder. Cumulative risk, assessed at 5/6-, 12/13-, and 19/20-years-old, predicted aforementioned outcomes at age 25/26 in every instance. Furthermore, number of risk factors was positively associated with number of negative outcomes. Finally, early risk accounted for variance beyond that explained by later risk in the prediction of CO. We discuss these findings in terms of five criteria posed by these data, positing a "mediated net of adversity" model, suggesting that CR may increase some central integrative factor, simultaneously augmenting risk across cognitive, quality of life, psychiatric and physical health outcomes.

    The demographic and ecological success of our species is frequently attributed to our capacity for cumulative culture. However, it is not yet known how humans combine social and asocial learning to generate effective strategies for learning in a cumulative cultural context. Here we explore how cumulative culture influences the relative merits of various pure and conditional learning strategies, including pure asocial and social learning, critical social learning, conditional social learning and individual refiner strategies. We replicate the Rogers' paradox in the cumulative setting. However, our analysis suggests that strategies that resolved Rogers' paradox in a non-cumulative setting may not necessarily evolve in a cumulative setting, thus different strategies will optimize cumulative and non-cumulative cultural learning.

    Culture can grow cumulatively if socially learnt behaviors are improved by individual learning before being passed on to the next generation. Previous authors showed that this kind of learning strategy is unlikely to be evolutionarily stable in the presence of a trade-off between learning and reproduction. This is because culture is a public good that is freely exploited by any member of the population in their model (cultural social dilemma). In this paper, we investigate the effect of vertical transmission (transmission from parents to offspring), which decreases the publicness of culture, on the evolution of cumulative culture in both infinite and finite population models. In the infinite population model, we confirm that culture accumulates largely as long as transmission is purely vertical. It turns out, however, that introduction of even slight oblique transmission drastically reduces the equilibrium level of culture. Even more surprisingly, if the population size is finite, culture hardly accumulates even under purely vertical transmission. This occurs because stochastic extinction due to random genetic drift prevents a learning strategy from accumulating enough culture. Overall, our theoretical results suggest that introducing vertical transmission alone does not really help solve the cultural social dilemma problem. Copyright © 2015 Elsevier Ltd.

    -management. This software has a production estimator called 305 mature equivalent to standardize records from different lactation numbers. The analyzed variables in the model were statistically significant. Cows of lower milk production have more chances to get pregnant than those with higher milk production. Cows that calves in colder seasons have more probabilities to get pregnant than those calves in hottest seasons. The relation was quadratic between the probability of getting pregnant at 100 days in milk and the number of lactation. The cumulative pregnancy rate at 100 days was greater with natural service, compared to AI but, the AI was related with greater levels of milk production. Therefore, the results suggest that new reproductive management designs specifically developed for given productive levels could increase the overall reproductive efficiency.

    The Environmental Research Letters focus issue on ‘Cumulative Emissions, Global Carbon Budgets and the Implications for Climate Mitigation Targets’ was launched in 2015 to highlight the emerging science of the climate response to cumulative emissions, and how this can inform efforts to decrease emissions fast enough to avoid dangerous climate impacts. The 22 research articles published represent a fantastic snapshot of the state-or-the-art in this field, covering both the science and policy aspects of cumulative emissions and carbon budget research. In this Review and Synthesis, we summarize the findings published in this focus issue, outline some suggestions for ongoing research needs, and present our assessment of the implications of this research for ongoing efforts to meet the goals of the Paris climate agreement.

    2017-08-03

    Cumulative trauma disorder (CTD) is a term for various injuries of the musculoskeletal and nervous systems that are caused by repetitive tasks, forceful exertions, vibrations, mechanical compression or sustained postures. Although there are many studies citing incidence of CTDs, there are fewer articles about its etiology, pathology and management. The aim of our study was to discuss the etiology, pathogenesis, prevention and management of CTDs. A literature search was performed using various electronic databases. The search was limited to articles in English language pertaining to randomized clinical trials, cohort studies and systematic reviews of CTDs. A total of 180 papers were identified to be relevant published since 1959. Out of these, 125 papers reported about its incidence and 50 about its conservative treatment. Workplace environment, same task repeatability and little variability, decreased time for rest, increase in expectations are major factors for developing CTDs. Prevention of its etiology and early diagnosis can be the best to decrease its incidence and severity. For effective management of CTDs, its treatment should be divided into Primordial, Primary, Secondary and Tertiary prevention.

    A wide range of optics issues for energy recovery linac (ERL)-based projects are illustrated through the presentation of ongoing projects covering both light sources, at Cornell and Daresbury and high energy and nuclear physics accelerators at the Brookhaven National Laboratory. This presented range of projects demonstrates how the different designs teams see the challenges of studying and solving optics issues for their particular project's ERLs, with studies appropriate to the stage of maturity of the project. Finally, as an illustration of the complexity and detail behind a single aspect of ERL optics design we present an overview of the highly important generic topic of longitudinal phase space evolution in ERLs

    This study tests the relation between eye-movements and thought processing. Subjects were given specific modality tasks (visual, gustatory, kinesthetic) and assessed on whether they responded with distinct eye-movements. Some subjects' eye-movements reflected ongoing thought processing. Instead of a universal pattern, as suggested by the neurolinguistic programming hypothesis, this study yielded subject-specific idiosyncratic eye-movements across all modalities. Included is a discussion of the neurolinguistic programming hypothesis regarding eye-movements and its implications for the eye-movement desensitization and reprocessing theory.

    Autosomal recessive polycystic kidney disease (ARPKD) is the most common childhood-onset ciliopathy. As treatments improve, more women are reaching reproductive age, but little is known about ARPKD and pregnancy. In our ongoing study on ARPKD and other ciliopathies, 12 females over 18 years of age were identified and systematically evaluated. Six had children; four carried pregnancies and delivered, one used assisted reproductive technology and had a surrogate carry the pregnancy, and one adopted. We report the outcomes of four pregnancies with live birth deliveries and two women who chose alternate family building options. Patient one was diagnosed at 6 months, and at age 21 had a pregnancy complicated by transient worsening of renal function (creatinine increase from 1.15 to 1.78 mg/dL). Patient two was diagnosed with ARPKD at age seven and had an uncomplicated pregnancy at age 23. Patient three was diagnosed incidentally with ARPKD at age 23, 3 months after completion of an uncomplicated pregnancy. Patient four who had an uncomplicated pregnancy at age 33 was diagnosed with ARPKD at age 46. Women with ARPKD face reproductive decisions largely bereft of information about the pregnancies of other ARPKD patients. We report four cases of pregnancy and ARPKD to expand current knowledge and encourage further research.

  11. Cumulative trauma and partner conflict predict post-traumatic stress disorder in postpartum African-American women.

    2017-08-01

    To describe relationships between cumulative trauma, partner conflict and post-traumatic stress in African-American postpartum women. Cumulative trauma exposure estimates for women in the USA range from 51-69%. During pregnancy, most trauma research has focused on physical injury to the mother. Post-traumatic stress disorder (PTSD) is associated with trauma and more prevalent in African-American women than women of other groups. Knowledge about both the rate and impact of cumulative trauma on pregnancy may contribute to our understanding of women seeking prenatal care, and disparities in infant morbidity and mortality. This retrospective, correlational, cross-sectional study took place on postpartum units of two Detroit hospitals. Participants were 150 African-American women aged between 18-45 who had given birth. Mothers completed the Cumulative Trauma Scale, Conflict Tactics Scale, Clinician Administered Post-traumatic Stress Scale, Edinburgh Postnatal Depression Scale and a Demographic Data form. Descriptive statistics, correlations and multiple regressions were used for data analysis. All participants reported at least one traumatic event in their lifetime. Cumulative trauma and partner conflict predicted PTSD, with the trauma of a life-threatening event for a loved one reported by 60% of the sample. Nearly, one-fourth of the women screened were at risk for PTSD. Increased cumulative trauma, increased partner conflict and lower level of education were related to higher rates of PTSD symptoms. Both cumulative trauma and partner conflict in the past year predict PTSD. Reasoning was used most often for partner conflict resolution. The results of this study offer additional knowledge regarding relationships between cumulative trauma, partner conflict and PTSD in African-American women. Healthcare providers need to be sensitive to patient life-threatening events, personal failures, abuse and other types of trauma. Current evidence supports the need to assess for

    Objectives  To determine how soon after delivery the risk of post-pregnancy hypertension increases in women with hypertensive disorders of pregnancy and how the risk evolves over time. Design  Nationwide register based cohort study. Setting  Denmark. Populations  482 972 primiparous women with a first live birth or stillbirth between 1995 and 2012 (cumulative incidence analyses), and 1 025 118 women with at least one live birth or stillbirth between 1978 and 2012 (Cox regression analyses). Main outcome measures  10 year cumulative incidences of post-pregnancy hypertension requiring treatment with prescription drugs, and hazard ratios estimated using Cox regression. Results  Of women with a hypertensive disorder of pregnancy in a first pregnancy in their 20s, 14% developed hypertension in the first decade post partum, compared with 4% of women with normotensive first pregnancies in their 20s. The corresponding percentages for women with a first pregnancy in their 40s were 32% and 11%, respectively. In the year after delivery, women with a hypertensive disorder of pregnancy had 12-fold to 25-fold higher rates of hypertension than did women with a normotensive pregnancy. Rates in women with a hypertensive disorder of pregnancy were threefold to 10-fold higher 1-10 years post partum and remained twice as high even 20 or more years later. Conclusions  The risk of hypertension associated with hypertensive disorders of pregnancy is high immediately after an affected pregnancy and persists for more than 20 years. Up to one third of women with a hypertensive disorder of pregnancy may develop hypertension within a decade of an affected pregnancy, indicating that cardiovascular disease prevention in these women should include blood pressure monitoring initiated soon after pregnancy.

  15. Cumulative cultural learning: Development and diversity

    Science.gov (United States)

    2017-01-01

    The complexity and variability of human culture is unmatched by any other species. Humans live in culturally constructed niches filled with artifacts, skills, beliefs, and practices that have been inherited, accumulated, and modified over generations. A causal account of the complexity of human culture must explain its distinguishing characteristics: It is cumulative and highly variable within and across populations. I propose that the psychological adaptations supporting cumulative cultural transmission are universal but are sufficiently flexible to support the acquisition of highly variable behavioral repertoires. This paper describes variation in the transmission practices (teaching) and acquisition strategies (imitation) that support cumulative cultural learning in childhood. Examining flexibility and variation in caregiver socialization and children’s learning extends our understanding of evolution in living systems by providing insight into the psychological foundations of cumulative cultural transmission—the cornerstone of human cultural diversity.

    Stressors associated with human activities interact in complex ways to affect marine ecosystems, yet we lack spatially explicit assessments of cumulative impacts on ecologically and economically key components such as marine predators. Here we develop a metric of cumulative utilization and impact (CUI) on marine predators by combining electronic tracking data of eight protected predator species (n=685 individuals) in the California Current Ecosystem with data on 24 anthropogenic stressors. We show significant variation in CUI with some of the highest impacts within US National Marine Sanctuaries. High variation in underlying species and cumulative impact distributions means that neither alone is sufficient for effective spatial management. Instead, comprehensive management approaches accounting for both cumulative human impacts and trade-offs among multiple stressors must be applied in planning the use of marine resources.

These functions originating from the probability theory being commonly used as features of deterministic signals, their classical properties are examined in this modified framework. We show additivity of cumulants, ensured in the case of independent random variables, requires here a different hypothesis. Practical applications are proposed, in particular an analysis of the failure of the JADE algorithm to separate some specific periodic signals.

  2. Cumulative effects assessment: Does scale matter?

    International Nuclear Information System (INIS)

    Therivel, Riki; Ross, Bill

    2007-01-01

    Cumulative effects assessment (CEA) is (or should be) an integral part of environmental assessment at both the project and the more strategic level. CEA helps to link the different scales of environmental assessment in that it focuses on how a given receptor is affected by the totality of plans, projects and activities, rather than on the effects of a particular plan or project. This article reviews how CEAs consider, and could consider, scale issues: spatial extent, level of detail, and temporal issues. It is based on an analysis of Canadian project-level CEAs and UK strategic-level CEAs. Based on a review of literature and, especially, case studies with which the authors are familiar, it concludes that scale issues are poorly considered at both levels, with particular problems being unclear or non-existing cumulative effects scoping methodologies; poor consideration of past or likely future human activities beyond the plan or project in question; attempts to apportion 'blame' for cumulative effects; and, at the plan level, limited management of cumulative effects caused particularly by the absence of consent regimes. Scale issues are important in most of these problems. However both strategic-level and project-level CEA have much potential for managing cumulative effects through better siting and phasing of development, demand reduction and other behavioural changes, and particularly through setting development consent rules for projects. The lack of strategic resource-based thresholds constrains the robust management of strategic-level cumulative effects

    Full Text Available Background. Discussion of the incidence of molar pregnancy and ectopic pregnancy. Role of salpingostomy and special considerations for postoperative care. Case. The patient is a 29-year-old G7P4 who presented with vaginal bleeding in the first trimester and was initially thought to have a spontaneous abortion. Ultrasound was performed due to ongoing symptoms and an adnexal mass was noted. She underwent uncomplicated salpingostomy and was later found to have a partial molar ectopic pregnancy. Conclusion. This case illustrates the rare occurrence of a molar ectopic pregnancy. There was no indication of molar pregnancy preoperatively and this case highlights the importance of submitting and reviewing pathological specimens.

    2012-01-01

    Teen pregnancy is a social problem not resolved in developing and some developed countries. Adolescent fecundity has become the most exact bio-demographic and health indicator of development. In developing countries that are expected to follow the sexual behaviour patterns of developed countries, without offering the levels of education and services for adolescents, the consequences will be adolescent fecundity and STI prevalence increase. The ignorance about sexuality and reproduction both in parents, teachers and adolescents increases the early initiation of coital relations and of unwanted pregnancies. Extreme poverty and being the son or daughter of an adolescent mother are risk factors of repeating the early pregnancy model. The application of predictive risk criteria in pregnant adolescents to facilitate the rational use of Health Services to diminish the maternal and perinatal mortality is discussed as well as the social factors associated with adolescent pregnancy as socioeconomic levels, structure - types and characteristics of the family, early leaving school, schooling after delivery, female employment, lack of sexual education, parental and family attitudes in different periods of adolescent pregnancy, adolescent decisions on pregnancy and children, unstable partner relationship and adoption as an option. Social consequences are analyzed as: incomplete education, more numerous families, difficulties in maternal role, abandonment by the partner, fewer possibilities of having a stable, qualified and well-paid job, greater difficulty in improving their socioeconomic level and less probability of social advancement, lack of protection of the recognition of the child. Finally, based on evidence, some measures that can reduce adverse consequences on adolescent mothers, fathers and their children are suggested. Copyright © 2012 S. Karger AG, Basel.

  18. Managing cumulative impacts: A key to sustainability?

    Energy Technology Data Exchange (ETDEWEB)

    Hunsaker, C.T.

    1994-12-31

    This paper addresses how science can be more effectively used in creating policy to manage cumulative effects on ecosystems. The paper focuses on the scientific techniques that we have to identify and to assess cumulative impacts on ecosystems. The term ``sustainable development`` was brought into common use by the World Commission on Environment and Development (The Brundtland Commission) in 1987. The Brundtland Commission report highlighted the need to simultaneously address developmental and environmental imperatives simultaneously by calling for development that ``meets the needs of the present generation without compromising the needs of future generations.`` We cannot claim to be working toward sustainable development until we can quantitatively assess cumulative impacts on the environment: The two concepts are inextricibally linked in that the elusiveness of cumulative effects likely has the greatest potential of keeping us from achieving sustainability. In this paper, assessment and management frameworks relevant to cumulative impacts are discussed along with recent literature on how to improve such assessments. When possible, examples are given for marine ecosystems.

    Despite many educational campaigns we still see burns caused by methylated spirit every year. We undertook a retrospective study to analyse the impact of this problem. We retrospectively collected data of all patients with burns caused by methylated spirit over twelve years from 1996 to 2008. Our main endpoints were: incidence, age, mechanism of injury, total body surface area (TBSA) burned, burn depth, need for surgery and length of hospital stay. Ninety-seven patients with methylated spirit burns were included. During the study period there was no decrease in the number of patients annually admitted to the burn unit with methylated spirit burns. 28% of the patients (n=27) were younger than eighteen years old, 15% (n=15) were ten years old or younger. The most common cause of burns was carelessness in activities involving barbecues, campfires and fondues. Mean TBSA burned was 16% (SD 12.4). 70% (n=68) had full thickness burns. 66% (n=64) needed grafting. Mean length of hospital stay was 23 days (SD 24.7). The use of methylated spirit is an ongoing problem, which continues to cause severe burns in adults and children. Therefore methylated spirit should be banned in households. We suggest sale only in specialised shops, clear labelling and mandatory warnings. Copyright © 2012 Elsevier Ltd and ISBI. All rights reserved.

  20. Ongoing Recovery Basic Information Tool (ORBIT)

    1993-01-01

    The Federal Drug Free Work Place Program (DFWP) has now matured to the point of being able to return employees to sensitive testing designated positions (TDP) after completion of treatment of their addiction. The known tendency of addicted individuals to suffer multiple relapses prior to their final recovery has resulted in several positive urine tests (relapses) occurring among those Federal employees who have already completed treatment and who have been returned to TDP's. The very real potential for further relapses occurring after additional employees return to TDP's will be a critical factor in the ultimate success of the DFWP and in the public's impression of the program's effectiveness. In response to this concern, NASA has begun development of its Ongoing Recovery Basic Information Tool (ORBIT) instrument. The aim of the NASA ORBIT is to provide Employee Assistance Program (EAP) professionals with an advanced clinical tool which will be helpful in supporting recovery from substance abuse and which will allow more accurate determinations of when clients may be successfully returned to sensitive positions.

  1. Perspectives on cumulative risks and impacts.

    Science.gov (United States)

    Faust, John B

    2010-01-01

    Cumulative risks and impacts have taken on different meanings in different regulatory and programmatic contexts at federal and state government levels. Traditional risk assessment methodologies, with considerable limitations, can provide a framework for the evaluation of cumulative risks from chemicals. Under an environmental justice program in California, cumulative impacts are defined to include exposures, public health effects, or environmental effects in a geographic area from the emission or discharge of environmental pollution from all sources, through all media. Furthermore, the evaluation of these effects should take into account sensitive populations and socioeconomic factors where possible and to the extent data are available. Key aspects to this potential approach include the consideration of exposures (versus risk), socioeconomic factors, the geographic or community-level assessment scale, and the inclusion of not only health effects but also environmental effects as contributors to impact. Assessments of this type extend the boundaries of the types of information that toxicologists generally provide for risk management decisions.

    Assuming existence of multiquark (mainly 12q) bags in nuclei the spectra of cumulative nucleons and mesons produced in high-energy particle-nucleus collisions are discussed. The exponential form of quark momentum distribution in 12q-bag (agreeing well with the experimental data on lepton-nucleus interactions at large q 2 ) is shown to result in quasi-exponential distribution of cumulative particles over the light-cone variable αsub(B). The dependence of f(αsub(B); psub(perpendicular)) (where psub(perpendicular) is the transverse momentum of the bag) upon psub(perpendicular) is considered. The yields of cumulative resonances as well as effects related to the u- and d-quark distributions in N > Z nuclei being different are dicscussed

    Full Text Available Background: Infertility tends to be the global challenge even in the second decade of the new millennium. Especially in developing countries like India, it is still one the most lethal social evil responsible for a big proportion of cases of psychological disturbances including suicide. Again, recently, few conditions other than communicable or Non-communicable diseases are given place among the categories of significant public health problems like Road Traffic Accidents, Burns, Poisoning, drowning and few more. But, for developing countries like India, the list is incomplete without inclusion of Infertility (there may be several others also. In public health, tuberculosis, leprosy and some other diseases are considered social diseases which produce social stigma for the patients and/or his family members.1 In same manner, Infertility is an important cause of social stigmatization since centuries for a couple suffering from, especially for woman involved. During a transitory phase of industrialization and socio-economic development, the situation is changed a minute smidgen at urban areas of India but at rural parts, sub-urban or even at urban slums (mainly among pockets of recent migrants the situation is as same as a few hundred years ago. A female of no religion, caste, social status or higher level of education are barred from some stringent mores related to infertility. Infertile females are still not allowed to take part in so many religious or social ceremonies; on the contrary, they have to face more harassment including domestic violence than their counterparts, who have given birth to the child. Due to social, psychological, economic disturbances, they are forced to take multiple sorts of treatments including religious quacks. So many infertile women are exploited physically and economically also in such weird ways of treatment to gain a pregnancy.

    Full Text Available BACKGROUND Pregnancy is a physiological status of a woman. Every organ is adapting in order to accept another human body. The main changes occur in the endocrine, immune, metabolic and vascular systems. The skin is no exception. Many skin changes during pregnancy are considered to be normal or physiological including striae gravidarum or melasma. These physiological skin changes are usually well tolerated by the pregnant woman. There is no balance between these systems, however, and abnormalities can appear. Immunologic status of the woman plays an important role in the manifestations exhibited in the skin. Alterations of the skin during pregnancy can be classified as physiologic skin changes, changes in pre-existing skin diseases and specific dermatoses of pregnancy. MATERIALS AND METHODS 200 pregnant women with skin manifestations attending Dermatology and Obstetric departments attached to Government General Hospital, Kurnool, were studied. 1. A detailed proforma was taken, which included: a. Detailed history including chief complaints related to skin. b. Onset in relation to duration of pregnancy. c. Complete general physical and systemic examination. d. Associated skin/medical disorders. 2. Investigations-CBP, CUE, RBS, LFT, HBsAg, VDRL, HIV 1 and 2 were done routinely. 3. KOH mount, saline mount and skin biopsy performed wherever required. Inclusion criteria- All pregnant women having skin lesions were included in the study irrespective of the duration of pregnancy and gravidity. Exclusion criteria- Pregnant women having any underlying medical diseases. All pregnant women attending antenatal OPD and those admitted into wards having symptoms related to skin and mucosa, at KIMS Hospital are studied. 1. Detailed history including chief complaints related to skin. 2. Onset in relation to duration of pregnancy. 3. Complete general physical and systemic examination. 4.

    EXAFS functions had been extracted from measurements on the K edge of Se at different temperatures between 20 and 300 K. The analysis of the EXAFS of the filtered first two shells has been done in the wavevector range laying between 2 and 15.5 A -1 in terms of the cumulants of the effective distribution of distances. The cumulants C 3 and C 4 obtained from the phase difference and the amplitude ratio methods have shown the anharmonicity in the vibrations of atoms around their equilibrium position.

  7. Mauna Kea volcano's ongoing 18-year swarm

    Wech, A.; Thelen, W. A.

    2017-12-01

    Mauna Kea is a large postshield-stage volcano that forms the highest peak on Hawaii Island. The 4,205-meter high volcano erupted most recently between 6,000 and 4,500 years ago and exhibits relatively low rates of seismicity, which are mostly tectonic in origin resulting from lithospheric flexure under the weight of the volcano. Here we identify deep repeating earthquakes occurring beneath the summit of Mauna Kea. These earthquakes, which are not part of the Hawaiian Volcano Observatory's regional network catalog, were initially detected through a systematic search for coherent seismicity using envelope cross-correlation, and subsequent analysis revealed the presence of a long-term, ongoing swarm. The events have energy concentrated at 2-7 Hz, and can be seen in filtered waveforms dating back to the earliest continuous data from a single station archived at IRIS from November 1999. We use a single-station (3 component) match-filter analysis to create a catalog of the repeating earthquakes for the past 18 years. Using two templates created through phase-weighted stacking of thousands of sta/lta-triggers, we find hundreds of thousands of M1.3-1.6 earthquakes repeating every 7-12 minutes throughout this entire time period, with many smaller events occurring in between. The earthquakes occur at 28-31 km depth directly beneath the summit within a conspicuous gap in seismicity surrounding the flanks of the volcano. Magnitudes and periodicity are remarkably stable long-term, but do exhibit slight variability and occasionally display higher variability on shorter time scales. Network geometry precludes obtaining a reliable focal mechanism, but we interpret the frequency content and hypocenters to infer a volcanic source distinct from the regional tectonic seismicity responding to the load of the island. In this model, the earthquakes may result from the slow, persistent degassing of a relic magma chamber at depth.

  8. Ongoing dengue epidemic - Angola, June 2013.

    Science.gov (United States)

    2013-06-21

    On April 1, 2013, the Public Health Directorate of Angola announced that six cases of dengue had been reported to the Ministry of Health of Angola (MHA). As of May 31, a total of 517 suspected dengue cases had been reported and tested for dengue with a rapid diagnostic test (RDT). A total of 313 (60.5%) specimens tested positive for dengue, including one from a patient who died. All suspected cases were reported from Luanda Province, except for two from Malanje Province. Confirmatory diagnostic testing of 49 specimens (43 RDT-positive and six RDT-negative) at the CDC Dengue Branch confirmed dengue virus (DENV) infection in 100% of the RDT-positive specimens and 50% of the RDT-negative specimens. Only DENV-1 was detected by molecular diagnostic testing. Phylogenetic analysis indicated this virus has been circulating in the region since at least 1968, strongly suggesting that dengue is endemic in Angola. Health-care professionals throughout Angola should be aware of the ongoing epidemic, the recommended practices for clinical management of dengue patients, and the need to report cases to MHA. Persons in Angola should seek medical care for acute febrile illness to reduce the risk for developing complications. Laboratory-confirmed dengue also has been reported from seven countries on four continents among persons who had recently traveled to Luanda, including 79 persons from Portugal. Angola is the third of four African countries to report a dengue outbreak in 2013. Persons returning from Africa with acute febrile illness should seek medical care, including testing for DENV infection, and suspected cases should be reported to public health authorities.

    We propose a genuine multiparty correlation measure for a multiparty quantum system as the trace norm of the cumulant of the state. The legitimacy of our multiparty correlation measure is explicitly demonstrated by proving it satisfies the five basic conditions required for a correlation measure. As an application we construct an efficient algorithm for the calculation of our measures for all stabilizer states

    2000-01-01

    Individuals sometimes express preferences that do not follow expected utility theory. Cumulative prospect theory adjusts for some phenomena by using decision weights rather than probabilities when analyzing a decision tree. The authors examined how probability transformations from cumulative prospect theory might alter a decision analysis of a prophylactic therapy in AIDS, eliciting utilities from patients with HIV infection (n = 75) and calculating expected outcomes using an established Markov model. They next focused on transformations of three sets of probabilities: 1) the probabilities used in calculating standard-gamble utility scores; 2) the probabilities of being in discrete Markov states; 3) the probabilities of transitioning between Markov states. The same prophylaxis strategy yielded the highest quality-adjusted survival under all transformations. For the average patient, prophylaxis appeared relatively less advantageous when standard-gamble utilities were transformed. Prophylaxis appeared relatively more advantageous when state probabilities were transformed and relatively less advantageous when transition probabilities were transformed. Transforming standard-gamble and transition probabilities simultaneously decreased the gain from prophylaxis by almost half. Sensitivity analysis indicated that even near-linear probability weighting transformations could substantially alter quality-adjusted survival estimates. The magnitude of benefit estimated in a decision-analytic model can change significantly after using cumulative prospect theory. Incorporating cumulative prospect theory into decision analysis can provide a form of sensitivity analysis and may help describe when people deviate from expected utility theory.

    A cumulative watershed effect (CWE) is any response to multiple land-use activities that is caused by, or results in, altered watershed function. The CWE issue is politically defined, as is the significance of particular impacts. But the processes generating CWEs are the traditional focus of geomorphology and ecology, and have thus been studied for decades. The CWE...

    In Mexico, 20% of the annual births are presented in women younger than 20 years old. Pregnancy in adolescents puts at risk mother and child health. This risk is major while the woman is younger, especially when the social and economic conditions are not favorable, which is decisive in later psychosocial development. It has been pointed out that the youths with low education, with minor academic and laboral expectations, with low self-esteem and assertiveness, tend to begin early their active sexual life, to use less frequently contraceptives, and in the case of younger women, to be pregnant, with the risk of abortion because they cannot to make the best decision. It is important to take into account the social context and the special characteristics of the family to understand situation of adolescent at risk of pregnancy.

  14. An evaluation paradigm for cumulative impact analysis

    Science.gov (United States)

    Stakhiv, Eugene Z.

    1988-09-01

    Cumulative impact analysis is examined from a conceptual decision-making perspective, focusing on its implicit and explicit purposes as suggested within the policy and procedures for environmental impact analysis of the National Environmental Policy Act of 1969 (NEPA) and its implementing regulations. In this article it is also linked to different evaluation and decision-making conventions, contrasting a regulatory context with a comprehensive planning framework. The specific problems that make the application of cumulative impact analysis a virtually intractable evaluation requirement are discussed in connection with the federal regulation of wetlands uses. The relatively familiar US Army Corps of Engineers' (the Corps) permit program, in conjunction with the Environmental Protection Agency's (EPA) responsibilities in managing its share of the Section 404 regulatory program requirements, is used throughout as the realistic context for highlighting certain pragmatic evaluation aspects of cumulative impact assessment. To understand the purposes of cumulative impact analysis (CIA), a key distinction must be made between the implied comprehensive and multiobjective evaluation purposes of CIA, promoted through the principles and policies contained in NEPA, and the more commonly conducted and limited assessment of cumulative effects (ACE), which focuses largely on the ecological effects of human actions. Based on current evaluation practices within the Corps' and EPA's permit programs, it is shown that the commonly used screening approach to regulating wetlands uses is not compatible with the purposes of CIA, nor is the environmental impact statement (EIS) an appropriate vehicle for evaluating the variety of objectives and trade-offs needed as part of CIA. A heuristic model that incorporates the basic elements of CIA is developed, including the idea of trade-offs among social, economic, and environmental protection goals carried out within the context of environmental

  16. Can monaural temporal masking explain the ongoing precedence effect?

    Freyman, Richard L; Morse-Fortier, Charlotte; Griffin, Amanda M; Zurek, Patrick M

    2018-02-01

    The precedence effect for transient sounds has been proposed to be based primarily on monaural processes, manifested by asymmetric temporal masking. This study explored the potential for monaural explanations with longer ("ongoing") sounds exhibiting the precedence effect. Transient stimuli were single lead-lag noise burst pairs; ongoing stimuli were trains of 63 burst pairs. Unlike with transients, monaural masking data for ongoing sounds showed no advantage for the lead, and are inconsistent with asymmetric audibility as an explanation for ongoing precedence. This result, along with supplementary measurements of interaural time discrimination, suggests different explanations for transient and ongoing precedence.

  17. Practical management of cumulative anthropogenic impacts with working marine examples.

    Human pressure on the environment is expanding and intensifying, especially in coastal and offshore areas. Major contributors to this are the current push for offshore renewable energy sources, which are thought of as environmentally friendly sources of power, as well as the continued demand for petroleum. Human disturbances, including the noise almost ubiquitously associated with human activity, are likely to increase the incidence, magnitude, and duration of adverse effects on marine life, including stress responses. Stress responses have the potential to induce fitness consequences for individuals, which add to more obvious directed takes (e.g., hunting or fishing) to increase the overall population-level impact. To meet the requirements of marine spatial planning and ecosystem-based management, many efforts are ongoing to quantify the cumulative impacts of all human actions on marine species or populations. Meanwhile, regulators face the challenge of managing these accumulating and interacting impacts with limited scientific guidance. We believe there is scientific support for capping the level of impact for (at a minimum) populations in decline or with unknown statuses. This cap on impact can be facilitated through implementation of regular application cycles for project authorization or improved programmatic and aggregated impact assessments that simultaneously consider multiple projects. Cross-company collaborations and a better incorporation of uncertainty into decision making could also help limit, if not reduce, cumulative impacts of multiple human activities. These simple management steps may also form the basis of a rudimentary form of marine spatial planning and could be used in support of future ecosystem-based management efforts. © 2014 Society for Conservation Biology.

    The European Integrated Data Archive (EIDA; http://www.orfeus-eu.org/eida/eida.html) is the distributed Data Centre system within ORFEUS, providing transparent access and services to high quality, seismic data across (currently) 9 large data archives in Europe. EIDA is growing, in terms of the number of participating data centres, the size of the archives, the variability of the data in the archives, the number of users, and the volume of downloads. The on-going success of EIDA is thus providing challenges that are the driving force behind the design of the next generation (NG) of EIDA, which is expected to be implemented within EPOS IP. EIDA ORFEUS must cope with further expansion of the system and more complex user requirements by developing new techniques and extended services. The EIDA NG is being designed to work on standard FDSN web services and two additional new web services: Routing Service and QC (quality controlled) service. This presentation highlights the challenges EIDA needs to address during the EPOS IP and focuses on these 2 new services. The Routing Service can be considered as the core of EIDA NG. It was designed to assist users and clients to locate data within a federated, decentralized data centre (e.g. EIDA). A detailed, FDSN-compliant specification of the service has been developed. Our implementation of this service will run at every EIDA node, but is also capable of running on a user's computer, allowing anyone to define virtual or integrate existing data centres. This (meta)service needs to be queried in order to locate the data. Some smart clients (in a beta status) have been also provided to offer the user an integrated view of the whole EIDA, hiding the complexity of its internal structure. The service is open and able to be queried by anyone without the need of credentials or authentication. The QC Service is developed to cope with user requirements to query for relevant data only. The web service provides detailed information on the

    A Zika virus epidemic is currently ongoing in the Americas. This virus is linked to congenital infections with potential severe neurodevelopmental dysfunction. However, incidence of fetal infection and whether this virus is responsible of other fetal complications are still unknown. National and international public health authorities recommend caution and several prevention measures. Declaration of Zika virus infection is now mandatory in France. Given the available knowledge on Zika virus, we suggest here a review of the current recommendations for management of pregnancy in case of suspicious or infection by Zika virus in a pregnant woman.

    Any limit on future global warming is associated with a quota on cumulative global CO 2 emissions. We translate this global carbon quota to regional and national scales, on a spectrum of sharing principles that extends from continuation of the present distribution of emissions to an equal per-capita distribution of cumulative emissions. A blend of these endpoints emerges as the most viable option. For a carbon quota consistent with a 2 C warming limit (relative to pre-industrial levels), the necessary long-term mitigation rates are very challenging (typically over 5% per year), both because of strong limits on future emissions from the global carbon quota and also the likely short-term persistence in emissions growth in many regions.

    Formal models have linked prehistoric and historical instances of technological change (e.g., the Upper Paleolithic transition, cultural loss in Holocene Tasmania, scientific progress since the late nineteenth century) to demographic change. According to these models, cumulation of technological complexity is inhibited by decreasing--while favoured by increasing--population levels. Here we show that these findings are contingent on how complexity is defined: demography plays a much more limited role in sustaining cumulative culture in case formal models deploy Herbert Simon's definition of complexity rather than the particular definitions of complexity hitherto assumed. Given that currently available empirical evidence doesn't afford discriminating proper from improper definitions of complexity, our robustness analyses put into question the force of recent demographic explanations of particular episodes of cultural change.

    Linder, Stephen H; Sexton, Ken

    2011-12-01

    In the absence of scientific consensus on an appropriate theoretical framework, cumulative risk assessment and related research have relied on speculative conceptual models. We argue for the importance of theoretical backing for such models and discuss 3 relevant theoretical frameworks, each supporting a distinctive "family" of models. Social determinant models postulate that unequal health outcomes are caused by structural inequalities; health disparity models envision social and contextual factors acting through individual behaviors and biological mechanisms; and multiple stressor models incorporate environmental agents, emphasizing the intermediary role of these and other stressors. The conclusion is that more careful reliance on established frameworks will lead directly to improvements in characterizing cumulative risk burdens and accounting for disproportionate adverse health effects.

    Science.gov (United States)

    Agenda Download the Workshop Agenda (PDF) The workshop included presentations and discussions by scientific experts pertaining to three topics (i.e., epigenetic changes associated with diverse stressors, key science considerations in understanding epigenetic changes, and practical application of epigenetic tools to address cumulative risks from environmental stressors), to address several questions under each topic, and included an opportunity for attendees to participate in break-out groups, provide comments and ask questions. Workshop Goals The workshop seeks to examine the opportunity for use of aggregate epigenetic change as an indicator in cumulative risk assessment for populations exposed to multiple stressors that affect epigenetic status. Epigenetic changes are specific molecular changes around DNA that alter expression of genes. Epigenetic changes include DNA methylation, formation of histone adducts, and changes in micro RNAs. Research today indicates that epigenetic changes are involved in many chronic diseases (cancer, cardiovascular disease, obesity, diabetes, mental health disorders, and asthma). Research has also linked a wide range of stressors including pollution and social factors with occurrence of epigenetic alterations. Epigenetic changes have the potential to reflect impacts of risk factors across multiple stages of life. Only recently receiving attention is the nexus between the factors of cumulative exposure to environmental

    Any physical system considered to study the QCD deconfinement phase transition certainly has a finite volume, so the finite size effects are inevitably present. This renders the location of the phase transition and the determination of its order as an extremely difficult task, even in the simplest known cases. In order to identify and locate the colorless QCD deconfinement transition point in finite volume T{sub 0}(V), a new approach based on the finite-size cumulant expansion of the order parameter and the ℒ{sub m,n}-Method is used. We have shown that both cumulants of higher order and their ratios, associated to the thermodynamical fluctuations of the order parameter, in QCD deconfinement phase transition behave in a particular enough way revealing pronounced oscillations in the transition region. The sign structure and the oscillatory behavior of these in the vicinity of the deconfinement phase transition point might be a sensitive probe and may allow one to elucidate their relation to the QCD phase transition point. In the context of our model, we have shown that the finite volume transition point is always associated to the appearance of a particular point in whole higher order cumulants under consideration.

    2008-08-01

    Localized irritation can limit treatment success with topical retinoids such as tretinoin and adapalene. The factors that influence irritant reactions have been shown to include individual skin sensitivity, the particular retinoid and concentration used, and the vehicle formulation. To compare the cutaneous tolerability of tretinoin 0.04% microsphere gel (TMG) with that of adapalene 0.3% gel and a standard tretinoin 0.025% cream. The results of 2 randomized, investigator-blinded studies of 2 to 3 weeks' duration, which utilized a split-face method to compare cumulative irritation scores induced by topical retinoids in subjects with healthy skin, were combined. Study 1 compared TMG 0.04% with adapalene 0.3% gel over 2 weeks, while study 2 compared TMG 0.04% with tretinoin 0.025% cream over 3 weeks. In study 1, TMG 0.04% was associated with significantly lower cumulative scores for erythema, dryness, and burning/stinging than adapalene 0.3% gel. However, in study 2, there were no significant differences in cumulative irritation scores between TMG 0.04% and tretinoin 0.025% cream. Measurements of erythema by a chromameter showed no significant differences between the test formulations in either study. Cutaneous tolerance of TMG 0.04% on the face was superior to that of adapalene 0.3% gel and similar to that of a standard tretinoin cream containing a lower concentration of the drug (0.025%).

    Machen, Leah; Clowse, Megan E B

    2017-05-01

    Vasculitis is more often a disease of women beyond their reproductive years, leaving the challenges of pregnancy management difficult to study. Pregnancy complications, including pregnancy loss and preterm birth, are higher among women with all forms of vasculitis. It seems that controlling the disease before pregnancy may improve the chances of pregnancy success. Many medications used for vasculitis are considered low risk in pregnancy, including prednisone, colchicine, azathioprine, and tumor necrosis factor inhibitors. Cyclophosphamide, methotrexate, and mycophenolate mofetil should be avoided in pregnancy. Controlling disease with low-risk medications may allow women with vasculitis to have the pregnancies they desire. Copyright © 2017 Elsevier Inc. All rights reserved.

  14. Missed opportunities: poor linkage into ongoing care for HIV-positive pregnant women in Mwanza, Tanzania.

    Directory of Open Access Journals (Sweden)

    Deborah Watson-Jones

    Full Text Available Global coverage of prevention of mother-to-child (PMTCT services reached 53% in 2009. However the number of pregnant women who test positive for HIV in antenatal clinics and who link into long-term HIV care is not known in many resource-poor countries. We measured the proportion of HIV-positive pregnant women in Mwanza city, Tanzania, who completed the cascade of care from antenatal HIV diagnosis to assessment and engagement in care in adult HIV clinics.Thirty antenatal and maternity ward health workers were interviewed about PMTCT activities. Nine antenatal HIV education sessions were observed. A prospective cohort of 403 HIV-positive women was enrolled by specially-trained clinicians and nurses on admission to delivery and followed for four months post-partum. Information was collected on referral and attendance at adult HIV clinics, eligibility for highly active antiretroviral therapy (HAART and reasons for lack of attendance.Overall, 70% of PMTCT health workers referred HIV-positive pregnant women to the HIV clinic for assessment and care. Antenatal HIV education sessions did not cover on-going care for HIV-infected women. Of 310 cohort participants tested in pregnancy, 51% had received an HIV clinic referral pre-delivery. Only 32% of 244 women followed to four months post-partum had attended an HIV clinic and been assessed for HAART eligibility. Non-attendance for HIV care was independently associated with fewer antenatal visits, poor PMTCT prophylaxis compliance, non-disclosure of HIV status, and non-Sukuma ethnicity.Most women identified as HIV-positive during pregnancy were not assessed for HAART eligibility during pregnancy or in the first four months post-partum. Initiating HAART at the antenatal clinic, improved counselling and linkages to care between PMTCT and adult HIV treatment services and reducing stigma surrounding disclosure of HIV results would benefit on-going care of HIV-positive pregnant women.

    1993-01-01

    The dynamical picture of the cumulative proton production in hA-collisions by means of diagram analysis with NN interaction described by a non-relativistic NN potential is considered. The contributions of the various mechanisms (spectator, direct and rescattering) for backward hemisphere proton production within the framework of this common approach is calculated. The emphasis is on the comparison of the relative contributions of these mechanisms for various angles, taking into account the interference of these contributions. Comparison with experimental data is also presented. (author)

    2015-05-01

    As predicted by Oppenheim et al’s (2010 implicit incremental learning account, WRP’s BCN RTs demonstrated strong (and significant repetition priming and semantic blocking effects (Figure 1. Similar to typical results from neurally intact undergraduates, WRP took longer to name pictures presented in semantically homogeneous blocks than in heterogeneous blocks, an effect that increased with each cycle. This result challenges accounts that ascribe cumulative semantic interference in this task to explicit memory mechanisms, instead suggesting that the effect has the sort of implicit learning bases that are typically spared in hippocampal amnesia.

    2017-07-01

    Studies in South Africa have reported unsafe levels of risky sexual behvaiours among adolescents and young adults, with the country reporting the highest burden of HIV/AIDS globally, as well as a high rate of teenage pregnancy. While determinants of risky sexual behaviours have been investigated for factors occurring at the individual and household levels, not fully explored in the literature is the effect of community level factors. Furthermore, it is unclear whether risk factors occurring within the ecology of adolescents and young adults act cumulatively to influence their sexual practices. This article aims to address this knowledge gap using a case study of the Cape Area Panel Study of adolescents and young adults in urban Cape Town, South Africa. The ecological framework was adopted to guide the selection of risk factors at the individual, household, and community levels. Multivariate linear discriminant function analyses were used to select significant risk factors for multiple sexual partnerships and used to produce risk indices for the respondents. The cumulative risk approach was applied to test whether significant risk factors acted cumulatively. Findings point to the importance of ecological factors in influencing outcomes of multiple sexual partnerships among respondents and further demonstrate that ecological risk factors may act cumulatively. These findings are important for South Africa that is grappling with teenage pregnancy and disproportionate HIV epidemic among the youth.

    The recently announced oil sands development of the Wood Buffalo Region in Alberta was the focus of this power point presentation. Both mining and in situ development is expected to total $26 billion and 2.6 million barrels per day of bitumen production. This paper described the economic, social and environmental challenges facing the resource development of this region. In addition to the proposed oil sands projects, this region will accommodate the needs of conventional oil and gas production, forestry, building of pipelines and power lines, municipal development, recreation, tourism, mining exploration and open cast mining. The Cumulative Environmental Management Association (CEMA) was inaugurated as a non-profit association in April 2000, and includes 41 members from all sectors. Its major role is to ensure a sustainable ecosystem and to avoid any cumulative impacts on wildlife. Other work underway includes the study of soil and plant species diversity, and the effects of air emissions on human health, wildlife and vegetation. The bioaccumulation of heavy metals and their impacts on surface water and fish is also under consideration to ensure the quality and quantity of surface water and ground water. 3 figs

    The cause of recurrent pregnancy loss often remains unknown. Possibly, pathophysiological pathways are shared with other pregnancy complications. All women with secondary recurrent pregnancy loss (SRPL) visiting Leiden University Medical Center (January 2000-2015) were included in this retrospective cohort to assess whether women with SRPL have a more complicated first pregnancy compared with control women. SRPL was defined as three or more consecutive pregnancy losses before 22 weeks of gestation, with a previous birth. The control group consisted of all Dutch nullipara delivering a singleton (January 2000-2015). Information was obtained from the Dutch Perinatal Registry. Outcomes were preeclampsia, preterm birth, post-term birth, intrauterine growth restriction, breach position, induction of labor, cesarean section, congenital abnormalities, perinatal death and severe hemorrhage in the first ongoing pregnancy. Subgroup analyses were performed for women with idiopathic SRPL and for women ≤35 years. In all, 172 women with SRPL and 1 196 178 control women were included. Women with SRPL were older and had a higher body mass index; 29.7 years vs. 28.8 years and 25.1 kg/m 2 vs. 24.1 kg/m 2 , respectively. Women with SRPL more often had a post-term birth (OR 1.86, 95% CI 1.10-3.17) and more perinatal deaths occurred in women with SRPL compared with the control group (OR 5.03, 95% CI 2.48-10.2). Similar results were found in both subgroup analyses. The first ongoing pregnancy of women with (idiopathic) SRPL is more often complicated by post-term birth and perinatal death. Revealing possible links between SRPL and these pregnancy complications might lead to a better understanding of underlying pathophysiology. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

    Since the Austrian propagation bill of July 1, 1992, was passed into law, Austrian physicians are committed to offer psychological counseling to women before performing assisted reproductive techniques, unless refused by the patient. The acceptance of psychotherapeutic counseling (PSITCO) and its influence on pregnancy rate were carefully reviewed. The study comprised 1156 consecutive patients (mean age, 33.3 years) and 1736 in vitro fertilization (IVF) cycles. In a consent form for follicle puncture, the patients were interviewed about PSITCO as follows. Several methods of psychological support during IVF-embryo transfer treatment were offered to patients especially psychotherapy, hypnotherapy, and relaxation and physical perception exercises. Forty-two and three-tenths percent of patients rejected PSITCO, 17.8% had already received PSITCO, and 10.4% were willing to undergo PSITCO. The acceptance of PSITCO had no relevance on pregnancy rate. The cumulative calculation of pregnancy rates showed that up to 56.4% of women who had undergone PSITCO conceived. In patients who were planning to undergo PSITCO, the pregnancy rate was 41.9%. Concerning the cumulative pregnancy rate, this study showed that patients who accepted or underwent PSITCO had a higher pregnancy rate than those who did not avail themselves of this possibility. These results should encourage sterility specialists to consider psychological therapy as an essential aspect of IVF. Solely a written declaration of the patient stating his/her awareness of the possibility to undergo PSITCO is, in our opinion, insufficient.

  8. Evolution model with a cumulative feedback coupling

    Science.gov (United States)

    Trimper, Steffen; Zabrocki, Knud; Schulz, Michael

    2002-05-01

    The paper is concerned with a toy model that generalizes the standard Lotka-Volterra equation for a certain population by introducing a competition between instantaneous and accumulative, history-dependent nonlinear feedback the origin of which could be a contribution from any kind of mismanagement in the past. The results depend on the sign of that additional cumulative loss or gain term of strength λ. In case of a positive coupling the system offers a maximum gain achieved after a finite time but the population will die out in the long time limit. In this case the instantaneous loss term of strength u is irrelevant and the model exhibits an exact solution. In the opposite case λ<0 the time evolution of the system is terminated in a crash after ts provided u=0. This singularity after a finite time can be avoided if u≠0. The approach may well be of relevance for the qualitative understanding of more realistic descriptions.

    INTRODUCTION: In the geriatric population, independent mobility is a key factor in determining readiness for discharge following acute hospitalization. The Cumulated Ambulation Score (CAS) is a potentially valuable score that allows day-to-day measurements of basic mobility. The CAS was developed...... and validated in older patients with hip fracture as an early postoperative predictor of short-term outcome, but it is also used to assess geriatric in-patients with acute medical illness. Despite the fast- accumulating literature on the CAS, to date no systematic review synthesizing its psychometric properties....... Of 49 studies identified, 17 examined the psychometric properties of the CAS. EVIDENCE SYNTHESIS: Most papers dealt with patients after hip fracture surgery, and only 4 studies assessed the CAS psychometric characteristics also in geriatric in-patients with acute medical illness. Two versions of CAS...

  10. Reducing twin pregnancy rates after IVF--elective single embryo transfer (eSET).

    LENUS (Irish Health Repository)

    Milne, P

    2010-01-01

    Multiple pregnancy is a major complication of IVF and is associated with increased maternal, fetal and neonatal morbidity. Elective single embryo transfer (eSET) during IVF, rather than the more standard transfer of two embryos (double embryo transfer or DET), has been shown to significantly reduce the multiple pregnancy rate associated with IVF, while maintaining acceptable pregnancy rates. Couples undergoing IVF in 2008 who met good prognostic criteria had eSET performed. Pregnancy and twinning rates were compared with those for similar couples in 2007 who had DET. Couples unsuccessful with a fresh cycle of treatment had subsequent frozen embryo transfer cycles with DET. The cumulative pregnancy rate was similar for each group. However there were no multiple pregnancies in the eSET group, compared to 4 twins of 5 pregnancies in the DET group. 96% of eligible couples agreed to eSET. ESET is successful in and acceptable to good prognosis Irish couples undergoing IVF.

    Objective Adverse experiences in childhood may influence cardiovascular risk in adulthood. We examined the prospective associations between types of psychosocial adversity as well as having multiple adversities (e.g., cumulative risk) with carotid intima-media thickness (IMT) and its progression among young adults. Higher cumulative risk score in childhood was expected to be associated with higher IMT and its progression. Methods Participants were 2265 men and women (age range: 24-39 years in 2001) from the on-going Cardiovascular Risk in Young Finns study whose carotid IMT were measured in 2001 and 2007. A cumulative psychosocial risk score, assessed at the study baseline in 1980, was derived from four separate aspects of the childhood environment that may impose risk (childhood stressful life-events, parental health behavior family, socioeconomic status, and childhood emotional environment). Results The cumulative risk score was associated with higher IMT in 2007 (b=.004; se=.001; padulthood, including adulthood health behavior, adulthood socioeconomic status and depressive symptoms. Among the individual childhood psychosocial risk categories, having more stressful life-events was associated with higher IMT in 2001 (b=.007; se=.003; p=.016) and poorer parental health behavior predicted higher IMT in 2007 (b=.004; se=.002; p=.031) after adjustment for age, sex and childhood cardiovascular risk factors. Conclusions Early life psychosocial environment influences cardiovascular risk later in life and considering cumulative childhood risk factors may be more informative than individual factors in predicting progression of preclinical atherosclerosis in adulthood.

  20. Humanoid infers Archimedes' principle: understanding physical relations and object affordances through cumulative learning experiences

    2016-01-01

    Emerging studies indicate that several species such as corvids, apes and children solve ‘The Crow and the Pitcher’ task (from Aesop's Fables) in diverse conditions. Hidden beneath this fascinating paradigm is a fundamental question: by cumulatively interacting with different objects, how can an agent abstract the underlying cause–effect relations to predict and creatively exploit potential affordances of novel objects in the context of sought goals? Re-enacting this Aesop's Fable task on a humanoid within an open-ended ‘learning–prediction–abstraction’ loop, we address this problem and (i) present a brain-guided neural framework that emulates rapid one-shot encoding of ongoing experiences into a long-term memory and (ii) propose four task-agnostic learning rules (elimination, growth, uncertainty and status quo) that correlate predictions from remembered past experiences with the unfolding present situation to gradually abstract the underlying causal relations. Driven by the proposed architecture, the ensuing robot behaviours illustrated causal learning and anticipation similar to natural agents. Results further demonstrate that by cumulatively interacting with few objects, the predictions of the robot in case of novel objects converge close to the physical law, i.e. the Archimedes principle: this being independent of both the objects explored during learning and the order of their cumulative exploration.

    2007-01-01

    Objective To assess the clinic value of a single maternal serum beta-human chorionic gonadotropin (β-hCG) assay 11 d after embryo transfer in ART pregnancies and to predict pregnancy outcome.Methods A total of 384 pregnancies after embryo transfer were included.Inviable pregnancies were defined as biochemical pregnancies,ectopic pregnancies and first trimester abortions.Ongoing pregnancies were defined as singleton pregnancies and multiple pregnancies whose gestation were achieved more than 12 weeks.Serum β-hCG concentrations were compared among different groups.Results On the post embryo transfer d 11,the mean β-hCG concentration of the ongoing pregnancy group (323.7±285.2 mIU/ml) was significantly higher than that of the inviable pregnancy group(81.4±68.1 mmIU/ml)(P<0.001).In multiple gestations,the levels of β-hCG were significantly higher compared with singleton pregnancies.If the β-hCG level was between 10 mIU/ml and 50 mIU/ml,the positive predictive value of biochemical pregnancies and ectopic pregnancies was 81.8%,the negative predictive value was 94.4%.If the level was less than 100 mIU/ml,the positive predictive value of first trimester abortions was 80.8% the negative predictive value was 77.8%.If the level was greater than 250 mIU/ml,the positive predictive value of multiple pregnancies was 83.3%.the negative predictive value was 74.4%.Conclusions A single serum β-hCG level on d 11 after embryo transfer has good predictive valuefor clinical pregnancy outcome in controlled ovarian stimulation cycles and helps to plan the subsequent follow-up.

    2012-01-01

    Objective: To study the cumulative radiation dose of multiple trauma patients during their hospitalization and to analyze the dose influence factors. Methods: The DLP for CT and DR were retrospectively collected from the patients during June, 2009 and April, 2011 at a university affiliated hospital. The cumulative radiation doses were calculated by summing typical effective doses of the anatomic regions scanned. Results: The cumulative radiation doses of 113 patients were collected. The maximum,minimum and the mean values of cumulative effective doses were 153.3, 16.48 mSv and (52.3 ± 26.6) mSv. Conclusions: Multiple trauma patients have high cumulative radiation exposure. Therefore, the management of cumulative radiation doses should be enhanced. To establish the individualized radiation exposure archives will be helpful for the clinicians and technicians to make decision whether to image again and how to select the imaging parameters.

    2008-01-01

    Omental pregnancy is a rare form of ectopic pregnancy and can be seen primarily or secondary to a tubal pregnancy. A 25-yeal-old woman presented with abdominal distention with pain and anemia without vaginal bleeding. After a provisional diagnosis of ruptured ectopic pregnancy, laparotomy was performed. On surgical exploration, the bilateral tubes and ovaries were intact, however, an omental pregnancy was detected as the cause of hemoperitoneum. Partial omentectomy was performed. Although most cases are secondary, presented here is an additional case of primary omental pregnancy at 12 weeks according to Studdiford's criteria. Histological evidence of neovascularization into the supporting tissue confirmed our diagnosis. A primary omental pregnancy should always be considered as a possible explanation for severe hemoperitoneum in ectopic pregnancies presenting with acute abdomen and with intact adnexes on surgical exploration.

    International studies have yielded contradictory results on efficacy of a sodium-restricted diet during pregnancy in preventing and curing hypertension of pregnancy. In the Netherlands three studies have been performed to investigate the value of dietary sodium restriction in pregnancy; they concerned epidemiology, prevention and treatment. Midwives often prescribed this dietary intervention. Urinary sodium excretion was not related to blood pressure changes in pregnancy. Dietary sodium restriction from the third month of pregnancy onwards did not reduce the incidence of pregnancy-induced hypertension. Maternal side effects were a decreased intake of nutrients, decreased maternal weight gain, lowered plasma volume and stimulation of the renin-angiotensin-aldosterone system. A dietary sodium restriction in women with early symptoms of pregnancy-induced hypertension showed no therapeutic effect on blood pressure. There is no place for dietary sodium restriction in the prevention or treatment of hypertension in pregnancy.

  20. Children neglected: Where cumulative risk theory fails.

    Science.gov (United States)

    O'Hara, Mandy; Legano, Lori; Homel, Peter; Walker-Descartes, Ingrid; Rojas, Mary; Laraque, Danielle

    2015-07-01

    Neglected children, by far the majority of children maltreated, experience an environment most deficient in cognitive stimulation and language exchange. When physical abuse co-occurs with neglect, there is more stimulation through negative parent-child interaction, which may lead to better cognitive outcomes, contrary to Cumulative Risk Theory. The purpose of the current study was to assess whether children only neglected perform worse on cognitive tasks than children neglected and physically abused. Utilizing LONGSCAN archived data, 271 children only neglected and 101 children neglected and physically abused in the first four years of life were compared. The two groups were assessed at age 6 on the WPPSI-R vocabulary and block design subtests, correlates of cognitive intelligence. Regression analyses were performed, controlling for additional predictors of poor cognitive outcome, including socioeconomic variables and caregiver depression. Children only neglected scored significantly worse than children neglected and abused on the WPPSI-R vocabulary subtest (p=0.03). The groups did not differ on the block design subtest (p=0.4). This study shows that for neglected children, additional abuse may not additively accumulate risk when considering intelligence outcomes. Children experiencing only neglect may need to be referred for services that address cognitive development, with emphasis on the linguistic environment, in order to best support the developmental challenges of neglected children.

  1. Standardization of the cumulative absolute velocity

    International Nuclear Information System (INIS)

    O'Hara, T.F.; Jacobson, J.P.

    1991-12-01

    EPRI NP-5930, ''A Criterion for Determining Exceedance of the Operating Basis Earthquake,'' was published in July 1988. As defined in that report, the Operating Basis Earthquake (OBE) is exceeded when both a response spectrum parameter and a second damage parameter, referred to as the Cumulative Absolute Velocity (CAV), are exceeded. In the review process of the above report, it was noted that the calculation of CAV could be confounded by time history records of long duration containing low (nondamaging) acceleration. Therefore, it is necessary to standardize the method of calculating CAV to account for record length. This standardized methodology allows consistent comparisons between future CAV calculations and the adjusted CAV threshold value based upon applying the standardized methodology to the data set presented in EPRI NP-5930. The recommended method to standardize the CAV calculation is to window its calculation on a second-by-second basis for a given time history. If the absolute acceleration exceeds 0.025g at any time during each one second interval, the earthquake records used in EPRI NP-5930 have been reanalyzed and the adjusted threshold of damage for CAV was found to be 0.16g-set

  9. Liver disease in pregnancy

    Institute of Scientific and Technical Information of China (English)

    Noel M Lee; Carla W Brady

    2009-01-01

    Liver diseases in pregnancy may be categorized into liver disorders that occur only in the setting of pregnancy and liver diseases that occur coincidentally with pregnancy. Hyperemesis gravidarum, preeclampsia/eclampsia, syndrome of hemolysis, elevated liver tests and low platelets (HELLP), acute fatty liver of pregnancy, and intrahepatic cholestasis of pregnancy are pregnancy-specific disorders that may cause elevations in liver tests and hepatic dysfunction. Chronic liver diseases, including cholestatic liver disease, autoimmune hepatitis, Wilson disease, and viral hepatitis may also be seen in pregnancy. Management of liver disease in pregnancy requires collaboration between obstetricians and gastroenterologists/hepatologists. Treatment of pregnancy-specific liver disorders usually involves delivery of the fetus and supportive care, whereas management of chronic liver disease in pregnancy is directed toward optimizing control of the liver disorder. Cirrhosis in the setting of pregnancy is less commonly observed but offers unique challenges for patients and practitioners. This article reviews the epidemiology, pathophysiology, diagnosis, and management of liver diseases seen in pregnancy.

    In this qualitative study, we explored women's pregnancy intentions and experiences of intimate partner violence before, during and after pregnancy. Unintended pregnancies in the context of intimate partner violence can have serious health, social and economic consequences for women and their children. Feminist and phenomenological philosophies underpinned the study to gain a richer understanding of women's experiences. Eleven women who had been pregnant in the previous two years were recruited from community-based women's refuges in one region of the UK. Of the 11 women, eight had unplanned pregnancies, two reported being coerced into early motherhood, and only one woman had purposively planned her pregnancy. Multiple in-depth interviews focused on participants' accounts of living with intimate partner violence. Experiential data analysis was used to identify, analyse and highlight themes. Three major themes were identified: men's control of contraception, partner's indiscriminate response to the pregnancy and women's mixed feelings about the pregnancy. Participants reported limited influence over their sexual relationship and birth control. Feelings of vulnerability about themselves and fear for their unborn babies' safety were intensified by their partners' continued violence during pregnancy. Women experiencing intimate partner violence were more likely to have an unintended pregnancy. This could be attributed to male dominance and fear, which impacts on a woman's ability to manage her birth control options. The women's initial excitement about their pregnancy diminished in the face of uncertainty and ongoing violence within their relationship. Women experiencing violence lack choice in relation to birth control options leading to unintended pregnancies. Interpreting the findings from the victim-perpetrator interactive spin theory of intimate partner violence provides a possible framework for midwives and nurses to better understand and respond to women

    Full Text Available Objective. To analyze a potential cumulative effect of life-time depression on dementia and Alzheimer’s disease (AD, with control of vascular factors (VFs. Methods. This study was a subanalysis of the Neurological Disorders in Central Spain (NEDICES study. Past and present depression, VFs, dementia status, and dementia due to AD were documented at study inception. Dementia status was also documented after three years. Four groups were created according to baseline data: never depression (nD, past depression (pD, present depression (prD, and present and past depression (prpD. Logistic regression was used. Results. Data of 1,807 subjects were investigated at baseline (mean age 74.3, 59.3% women, and 1,376 (81.6% subjects were evaluated after three years. The prevalence of dementia at baseline was 6.7%, and dementia incidence was 6.3%. An effect of depression was observed on dementia prevalence (OR [CI 95%] 1.84 [1.01–3.35] for prD and 2.73 [1.08–6.87] for prpD, and on dementia due to AD (OR 1.98 [0.98–3.99] for prD and OR 3.98 [1.48–10.71] for prpD (fully adjusted models, nD as reference. Depression did not influence dementia incidence. Conclusions. Present depression and, particularly, present and past depression are associated with dementia at old age. Multiple mechanisms, including toxic effect of depression on hippocampal neurons, plausibly explain these associations.

    The neonatal Fc receptor (FcRn) plays an important and well-known role in antibody recycling in endothelial and hematopoietic cells and thus it influences the systemic pharmacokinetics (PK) of immunoglobulin G (IgG). However, considerably less is known about FcRn’s role in the metabolism of IgG within individual tissues after intravenous administration. To elucidate the organ distribution and gain insight into the metabolism of humanized IgG1 antibodies with different binding affinities FcRn, comparative biodistribution studies in normal CD-1 mice were conducted. Here, we generated variants of herpes simplex virus glycoprotein D-specific antibody (humanized anti-gD) with increased and decreased FcRn binding affinity by genetic engineering without affecting antigen specificity. These antibodies were expressed in Chinese hamster ovary cell lines, purified and paired radiolabeled with iodine-125 and indium-111. Equal amounts of I-125-labeled and In-111-labeled antibodies were mixed and intravenously administered into mice at 5 mg/kg. This approach allowed us to measure both the real-time IgG uptake (I-125) and cumulative uptake of IgG and catabolites (In-111) in individual tissues up to 1 week post-injection. The PK and distribution of the wild-type IgG and the variant with enhanced binding for FcRn were largely similar to each other, but vastly different for the rapidly cleared low-FcRn-binding variant. Uptake in individual tissues varied across time, FcRn binding affinity, and radiolabeling method. The liver and spleen emerged as the most concentrated sites of IgG catabolism in the absence of FcRn protection. These data provide an increased understanding of FcRn’s role in antibody PK and catabolism at the tissue level. PMID:24572100

    Full Text Available We present two cases of carnitine deficiency in pregnancy. In our first case, systematic screening revealed L-carnitine deficiency in the first born of an asymptomatic mother. In the course of her second pregnancy, maternal carnitine levels showed a deficiency as well. In a second case, a mother known with carnitine deficiency under supplementation was followed throughout her pregnancy. Both pregnancies had an uneventful outcome. Because carnitine deficiency can have serious complications, supplementation with carnitine is advised. This supplementation should be continued throughout pregnancy according to plasma concentrations.

    Full Text Available Juvenile dermatomyositis has variable clinical presentations both in and outside of pregnancy. A literature review indicated that optimal maternal and fetal outcomes can be anticipated when the pregnancy is undertaken while the disease is in remission. Poorer outcomes are associated with flare-up of the disease in early pregnancy compared with exacerbation in the second or third trimester, when fetal prognosis is usually good. We present a case of JDM in pregnancy with disease exacerbation late in pregnancy and review of the relevant literature.

    Routine exercise should be recommended to healthy pregnant women after consultation with an obstetric provider. Even pregnant women who have not been exercising regularly can gradually increase their exercise during pregnancy. Regular exercise during pregnancy promotes overall wellness and helps maintain appropriate gestational weight gain and appropriate fetal weight gain. Exercise in pregnancy may also reduce hypertensive disorders of pregnancy and gestational diabetes, and may be associated with shorter first stage of labor and decreased risk for cesarean section. Exercise in pregnancy is safe for pregnant women and their fetuses and can have multiple health benefits. Copyright © 2017 Elsevier Inc. All rights reserved.

    Hyperthyroidism is a rare complication of molar pregnancy. We report a 39-year-old woman who presented a thyrotoxic syndrome accompanying a molar pregnancy. Serum thyroid hormones were elevated and returned to normal level after uterine evacuation of a molar pregnancy. The authors detail the role of thyroid stimulating property of human gonadotropin chorionic hormone and its structural changes during the gestational trophoblastic diseases. These changes give the latter the thyroid stimulating properties and signs of hyperthyroidism. Molar pregnancy may be a cause of hyperthyroidism. The diagnosis of molar pregnancy should be a mention to thyrotoxicosique syndrome in a woman of childbearing age. Copyright © 2013. Published by Elsevier SAS.

    Full Text Available The management of idiopathic thrombocytopenic purpura (ITP during pregnancy, especially with ongoing bleeding diathesis, has not been highlighted sufficiently in the literature. Aortocaval compression and reduction in uteroplacental circulation resulting in foetal hypoxia and acidosis, Mendelson′s syndrome due to gravid uterus, trauma to airway with resultant haemorrhage and aspiration into lungs, compromised airway due to short neck, anasarca and heavy breast, limitation in using invasive monitoring and regional anaesthesia and uncontrolled bleeding leading to placental hypoperfusion and foetal hypoxia are some of the important risks. In the present case report, anaesthetic management for splenectomy during pregnancy complicated with pregnancy induced hypertension and bleeding diathesis secondary to ITP is described with reference to above risks.

    2016-03-01

    Diabetes insipidus (DI) in pregnancy is a heterogeneous syndrome, most classically presenting with polyuria and polydipsia that can complicate approximately 1 in 30,000 pregnancies. The presentation can involve exacerbation of central or nephrogenic DI during pregnancy, which may have been either overt or subclinical prior to pregnancy. Women without preexisting DI can also be affected by the actions of placental vasopressinase which increases in activity between the 4th and 38th weeks of gestation, leading to accelerated metabolism of AVP and causing a transient form of DI of pregnancy. This type of DI may be associated with certain complications during pregnancy and delivery, such as preeclampsia. Management of DI of pregnancy depends on the pathophysiology of the disease; forms of DI that lack AVP can be treated with desmopressin (DDAVP), while forms of DI that involve resistance to AVP require evaluation of the underlying causes.

    2016-06-01

    Diabetes insipidus (DI) is a rare complication of pregnancy. It is usually transient, being due to increased placental production of vasopressinase that inactivates circulating vasopressin. Gestational, transient DI occurs late in pregnancy and disappears few days after delivery. Acquired central DI can also occur during pregnancy, for example in a patient with hypophysitis or neuroinfundibulitis during late pregnancy or postpartum. Finally, pre-existing central or nephrogenic DI may occasionally be unmasked by pregnancy. Treatment with dDAVP (desmopressin, Minirin(®)) is very effective on transient DI of pregnancy and also on pre-existing or acquired central DI. Contrary to vasopressin, dDAVP is not degraded by vasopressinase. Nephrogenic DI is insensitive to dDAVP and is therefore more difficult to treat during pregnancy if fluid intake needs to be restricted. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Are there differences in preconception cardiovascular function between women who have a viable pregnancy and those who have a first trimester miscarriage? Preconception cardiovascular function of central haemodynamics and arterial function are similar between women who have a viable pregnancy and those who have a first trimester miscarriage. Miscarriages have been associated with increased long-term cardiovascular disease risk, and arterial and cardiovascular dysfunction has been hypothesised as the common link. It is not known if these risks are present prior to pregnancy or are a reflection of poor arterial and haemodynamic adaptation to pregnancy. This prospective longitudinal preconception cohort study was conducted over 18 months. In total, 367 participants were recruited pre-pregnancy, from which 197 pregnancies were recorded; 39 of these pregnancies ended in first trimester miscarriage. Complete longitudinal data were available for 172 pregnancies (140 viable pregnancies, 32 first trimester miscarriages) from pre-pregnancy to 6 weeks gestation. This was a single site study based at a maternity hospital in London. Healthy women were recruited prior to natural conception and followed up once they became pregnant. All underwent haemodynamic [cardiac output (CO), peripheral vascular resistance (PVR)] and arterial function [aortic augmentation index (AIx) and pulse wave velocity (PWV)] testing prior to pregnancy and at 6 weeks gestation, using non-invasive devices (gas re-breathing method, Innocor® and an occilometric device, Vicorder®). Cross-sectional measurements at pre-pregnancy and 6 weeks gestation and a longitudinal analysis of changes were compared between women who had a subsequent viable pregnancy, and those who had a subsequent first trimester miscarriage. There were no differences between women destined to have a healthy ongoing pregnancy compared to those who miscarried, in terms of baseline cardiovascular function, assessed by CO, PVR, PWV or AIx

  12. High cumulants of conserved charges and their statistical uncertainties

    We study the influence of measured high cumulants of conserved charges on their associated statistical uncertainties in relativistic heavy-ion collisions. With a given number of events, the measured cumulants randomly fluctuate with an approximately normal distribution, while the estimated statistical uncertainties are found to be correlated with corresponding values of the obtained cumulants. Generally, with a given number of events, the larger the cumulants we measure, the larger the statistical uncertainties that are estimated. The error-weighted averaged cumulants are dependent on statistics. Despite this effect, however, it is found that the three sigma rule of thumb is still applicable when the statistics are above one million.

  13. Anaemia and pregnancy: Anaesthetic implications

    Directory of Open Access Journals (Sweden)

    Anju Grewal

    2010-01-01

    Full Text Available Anaemia in pregnancy defined as haemoglobin (Hb level of < 10 gm/dL, is a qualitative or quantitative deficiency of Hb or red blood cells in circulation resulting in reduced oxygen (O 2 -carrying capacity of the blood. Compensatory mechanisms in the form of increase in cardiac output (CO, PaO 2 , 2,3 diphosphoglycerate levels, rightward shift in the oxygen dissociation curve (ODC, decrease in blood viscosity and release of renal erythropoietin, get activated to variable degrees to maintain tissue oxygenation and offset the decreases in arterial O 2 content. Parturients with concomitant medical diseases or those with acute ongoing blood losses may get decompensated, leading to serious consequences like right heart failure, angina or tissue hypoxemia in severe anaemia. Preoperative evaluation is aimed at assessing the severity and cause of anaemia. The concept of an acceptable Hb level varies with the underlying medical condition, extent of physiological compensation, the threat of bleeding and ongoing blood losses. The main anaesthetic considerations are to minimize factors interfering with O 2 delivery, prevent any increase in oxygen consumption and to optimize the partial pressure of O 2 in the arterial blood. Both general anaesthesia and regional anaesthesia can be employed judiciously. Monitoring should focus mainly on the adequacy of perfusion and oxygenation of vital organs. Hypoxia, hyperventilation, hypothermia, acidosis and other conditions that shift the ODC to left should be avoided. Any decrease in CO should be averted and aggressively treated.

  14. Towards Greenland Glaciation: cumulative or abrupt transition?

    2017-04-01

    During the mid-Pliocene warming period (3-3.3 Ma BP), the global annual mean temperatures inferred by data and model studies were 2-3° warmer than pre-industrial values. Accordingly, Greenland ice sheet volume is supposed to reach at the most, only half of that of present-day [Haywood et al. 2010]. Around 2.7-2.6 Ma BP, just ˜ 500 kyr after the warming peak of mid-Pliocene, the Greenland ice sheet has reached its full size [Lunt et al. 2008]. A crucial question concerns the evolution of the Greenland ice sheet from half to full size during the 3 - 2.5 Ma period. Data show a decreasing trend of atmospheric CO2 concentration from 3 Ma to 2.5 Ma [Seki et al.2010; Bartoli et al. 2011; Martinez et al. 2015]. However, a recent study [Contoux et al. 2015] suggests that a lowering of CO2 is not sufficient to initiate a perennial glaciation on Greenland and must be combined with low summer insolation to preserve the ice sheet during insolation maxima. This suggests rather a cumulative process than an abrupt event. In order to diagnose the evolution of the ice sheet build-up, we carry on, for the first time, a transient simulation of climate and ice sheet evolutions from 3 Ma to 2.5 Ma. This strategy enables us to investigate the waxing and waning of the ice sheet during several orbital cycles. We use a tri-dimensional interpolation method designed by Ladant et al. (2014), which allows the evolution of CO2 concentration and of orbital parameters, and the evolution of the Greenland ice sheet size to be taken into account. By interpolating climatic snapshot simulations ran with various possible combinations of CO2, orbits and ice sheet sizes, we can build a continuous climatic forcing that is then used to provide 500 kyrs-long ice sheet simulations. With such a tool, we may offer a physically based answer to different CO2 reconstructions scenarios and analyse which one is the most consistent with Greenland ice sheet buildup.

    Can the ability of the endometriosis fertility index (EFI) to predict non-assisted reproductive technology (ART) pregnancy after endometriosis surgery be confirmed by an external validation study? The significant relationship between the EFI score and the time to non-ART pregnancy observed in our study represents an external validation of this scoring system. The EFI was previously developed and tested prospectively in a single center, but up to now no external validation has been published. Our data provide validation of the EFI in an external fertility unit on a robust scientific basis, to identify couples with a good prognosis for spontaneous conception who can therefore defer ART treatment, regardless of their revised American Fertility Society (rAFS) endometriosis staging. Retrospective cohort study where the EFI was calculated based on history and detailed surgical findings, and related to pregnancy outcome in 233 women attempting non-ART conception immediately after surgery; all data used for EFI calculation and analysis of reproductive outcome had been collected prospectively as part of another study. The EFI score was calculated (score 0-10) for 233 women with all rAFS endometriosis stages (minimal-mild, n = 75; moderate-severe, n = 158) after endometriosis surgery (1 September 2006-30 September 2010) in a university hospital-based reproductive medicine unit with combined expertise in reproductive surgery and medically assisted reproduction. All participants attempted non-ART conception immediately after surgery by natural intercourse, ovulation induction with timed intercourse or intrauterine insemination (with or without ovulation induction or controlled ovarian stimulation). All analyses were performed for three different definitions of pregnancy [overall (any HCG >25 IU/l), clinical and ongoing >20 weeks]. Six groups were distinguished (EFI scores 1-3, 4, 5, 6, 7+8, 9+10), and Kaplan-Meier (K-M) estimates for cumulative pregnancy rate were calculated

    To provide clinicians with a review of recent research and clinically applicable tools regarding teen pregnancy. Teen pregnancy rates have declined but still remain a significant problem in the USA. Teen pregnancy prevention was identified by Centers for Disease Control and Prevention as one of its top six priorities, which is increasing research and intervention data. Long-acting contraceptive methods are acceptable to teens and have been shown to reduce teen birth rates. Pregnant teens need special attention to counseling on pregnancy options and reducing risk during pregnancy with regular prenatal care. Postpartum teens should be encouraged and supported to breastfeed, monitored for depression, and have access to reliable contraception to avoid repeat undesired pregnancy. This review highlights important issues for all providers caring for female adolescents and those who may encounter teen pregnancy. Foremost prevention of teen pregnancy by comprehensive sexual education and access to contraception is the priority. Educating patients and healthcare providers about safety and efficacy of long-acting reversible contraception is a good step to reducing undesired teen pregnancies. Rates of postpartum depression are greater in adolescents than in adults, and adolescent mothers need to be screened and monitored for depression. Strategies to avoid another undesired pregnancy shortly after delivery should be implemented.

    Whether cumulative stress, including both chronic stress and adverse life events, is associated with decreased heart rate variability (HRV), a non-invasive measure of autonomic status which predicts poor cardiovascular outcomes, is unknown. Healthy community dwelling volunteers (N = 157, mean age 29 years) participated in the Cumulative Stress/Adversity Interview (CAI), a 140-item event interview measuring cumulative adversity including major life events, life trauma, recent life events and chronic stressors, and underwent 24-h ambulatory ECG monitoring. HRV was analyzed in the frequency domain and standard deviation of NN intervals (SDNN) calculated. Initial simple regression analyses revealed that total cumulative stress score, chronic stressors and cumulative adverse life events (CALE) were all inversely associated with ultra low-frequency (ULF), very low-frequency (VLF) and low-frequency (LF) power and SDNN (all p accounting for additional appreciable variance. For VLF and LF, both total cumulative stress and chronic stress significantly contributed to the variance alone but were not longer significant after adjusting for race and health behaviors. In summary, total cumulative stress, and its components of adverse life events and chronic stress were associated with decreased cardiac autonomic function as measured by HRV. Findings suggest one potential mechanism by which stress may exert adverse effects on mortality in healthy individuals. Primary preventive strategies including stress management may prove beneficial.

    During pregnancy thyroid hormones have profound effects on embryonal/fetal development and maternal health. Therefore, thyroid gland disorders should be immediately diagnosed and adequately treated. Pregnancy-specific physiological alterations during pregnancy cause changes in the reference interval for thyroid-stimulating hormone levels and trimester-specific thresholds must be taken into account. This article summarizes the most important diagnostic and therapeutic aspects before, during and after pregnancy. With reference to the period prior to pregnancy, the article discusses iodide supplementation, preconceptional examination of thyroid gland metabolism and the importance of thyroid gland functional disorders for fertility and fulfilling the desire to have children. With a view to the period during pregnancy, the effect of hypothyroxinemia, hypothyroidism, and hyperthyroidism as well as the effects of their treatment on the development of the child are explained. Finally, a description is given of what must be paid attention to in the breast-feeding period and in postpartum thyroiditis.

    Full Text Available Pregnancy loss is an important aspect of equine practice due to the economic and emotional loss that it engenders. Pregnancy loss is often divided in two categories: early pregnancy loss (EPL or embryonic death (ED (first 42 days and fetal losses (after 42 days. Diagnosis of the causes of pregnancy loss is often very challenging. Many of the causes of EPL remain poorly documented but studies on embryo development and embryo-uterine interaction have been able to shed some light on predisposing factors. Fetal losses or abortions are dominated by infectious causes and particularly bacterial placentitis. Detailed reviews of pregnancy loss were recently published by the authors (Tibary et al., 2012; Tibary and Pearson, 2012; Tibary et al., 2014. The objective of this paper is to provide an overview of the epidemiology, etiology, diagnosis and prevention of pregnancy loss in the mare.

While most of the described changes are transient in nature, others extend beyond delivery and may lead to permanent visual impairment. Also, pregnancy can affect vision through systemic disease that are either specific to the pregnancy itself or systemic diseases that occur more frequently in relation to pregnancy. Neuro-ophthalmological disorders should be kept in mind in pregnant women presenting with visual acuity or field loss. Therefore, it is important to be aware of the ocular changes in pregnancy in order to counsel and advice women who currently are, or are planning to become pregnant.

    We intend to describe the sexual behaviour of pregnancies women. Family Planning Center Nóvoa Santos, of Galician Health Service (SERGAS), of Ourense (SPAIN). 206 pregnancies women that are attended in a obstetric psychoprophylaxis's programme, during two years (January/93-January/95). We analysed the social economic, of reproduction, of medical attention and psycho-sexual variables. We use the PRESTA and SPSS statistics programmes. The average age is 28 years old, is married, has elementary studies and this is the first pregnancy. Her pregnancy is desire and normally developed. Her sexual desire and intercourse frequency is the same (1-2 per week); the intercourse is pleasant and the more habitual position is she over. Some times, the couple has relations without coitus and she practises the masturbation, and she enjoy of this practice. The pregnancies women have different sexual behaviours. They are satisfied with all them. The health' professional should favour the complete enjoy of the sexuality during the pregnancy.

    Abdominal pregnancy, a rare diagnosis, belongs to the ectopic pregnancy group, the leading cause of pregnancy related exitus. The positive diagnosis is very difficult to establish most often in an acute setting, leading to a staggering percent of feto-maternal morbidity and mortality. We present the case of 26-weeks-old abdominal pregnancy with partial feto-placental detachment in a patient, after hysteroscopy and in vitro fertilization, which until the acute symptoms that led to emergency laparotomy went unrecognized. The patient recovered completely and satisfactorily after surgery and, due to the high risk of uterine rupture with regard to a second pregnancy, opted for a surrogate mother. Abdominal pregnancy can be regarded as a difficult to establish diagnosis, with a greater chance in case of increased awareness. It is compulsory to be well informed in order not to be surprised by the diagnosis and to apply the correct treatment immediately as the morbidity and mortality rate is elevated.

    Full Text Available In this article, we present a case of subacute thyroiditis occurring in the first trimester of pregnancy in a 33-years-old pregnant patient. Thyrotoxicosis during pregnancy is a rare condition and occurs in 0.1 to 0.4% of all pregnancies. Graves' Disease and transient gestational thyrotoxicosis constitute the majority of emerging thyrotoxicosis during pregnancy. Subacute thyroiditis may also cause temporary thyrotoxicosis. Although the majority of the patients recover without treatment, complications in the pregnancy should be considered and each patient must be evaluated individually. As a result, differential diagnosis of thyrotoxicosis in pregnancy and treatment plan should be done well and subacute thyroiditis should be considered in differential diagnosis.

    The formulation of perturbation expansions for a quantum field theory of strongly interacting systems in a general non-equilibrium state is discussed. Non-vanishing initial correlations are included in the formulation of the perturbation expansion in terms of cumulants. The cumulants are shown to be the suitable candidate for summing up the perturbation expansion. Also a linked-cluster theorem for the perturbation series with cumulants is presented. Finally a generating functional of the perturbation series with initial correlations is studied. We apply the methods to a simple model of a fermion-boson system. (orig.)

    Cushing's syndrome is a rare condition in the general population and is even less common during pregnancy with only a few cases reported in literature. The diagnosis of Cushing's syndrome may be difficult during pregnancy because the typical features of the disorder and pregnancy may overlap. However, Cushing's syndrome results in increased fetal and maternal complications, and diagnosis and treatment are critical. This report describes a case of 26-year-old female at the 19th week of pregnancy with symptoms and signs of hypercortisolism, where ACTH-independent Cushing's syndrome was diagnosed and treated by robotic laparoscopic adrenalectomy at the 21th week of gestation.

    Malignant melanoma is the most common malignancy during pregnancy, and is diagnosed during childbearing age in approximately one-third of women diagnosed with melanoma. The impact of hormonal changes during pregnancy and from iatrogenic hormones on melanoma is controversial. Women undergo immunologic changes during pregnancy that may decrease tumor surveillance. In addition, hormone receptors are found on some melanomas. In spite of these observations, the preponderance of evidence does not support a poorer prognosis for pregnancy-associated melanomas. There is also a lack of evidence that oral contraceptives or hormone replacement therapy worsens melanoma prognosis. Copyright © 2016 American Academy of Dermatology, Inc. Published by Elsevier Inc.

    Solomon, Gina M; Morello-Frosch, Rachel; Zeise, Lauren; Faust, John B

    2016-01-01

    Many communities are located near multiple sources of pollution, including current and former industrial sites, major roadways, and agricultural operations. Populations in such locations are predominantly low-income, with a large percentage of minorities and non-English speakers. These communities face challenges that can affect the health of their residents, including limited access to health care, a shortage of grocery stores, poor housing quality, and a lack of parks and open spaces. Environmental exposures may interact with social stressors, thereby worsening health outcomes. Age, genetic characteristics, and preexisting health conditions increase the risk of adverse health effects from exposure to pollutants. There are existing approaches for characterizing cumulative exposures, cumulative risks, and cumulative health impacts. Although such approaches have merit, they also have significant constraints. New developments in exposure monitoring, mapping, toxicology, and epidemiology, especially when informed by community participation, have the potential to advance the science on cumulative impacts and to improve decision making.

    Online scheduling is recognized as the crucial decision-making process of production control at a phase of “being in production" according to the released shop floor schedule. Online scheduling can be also considered as one of key enablers to realize prompt capable-to-promise as well as available-to-promise to customers along with reducing production lead times under recent globalized competitive markets. Online Scheduling in Manufacturing introduces new approaches to online scheduling based on a concept of cumulative delay. The cumulative delay is regarded as consolidated information of uncertainties under a dynamic environment in manufacturing and can be collected constantly without much effort at any points in time during a schedule execution. In this approach, the cumulative delay of the schedule has the important role of a criterion for making a decision whether or not a schedule revision is carried out. The cumulative delay approach to trigger schedule revisions has the following capabilities for the ...

    2010-02-01

    This retrospective study calculated the cumulative radiation dose for children with cystic fibrosis (CF) attending a tertiary CF centre. Information on 77 children with a mean age of 9.5 years, a follow up time of 658 person years and 1757 studies including 1485 chest radiographs, 215 abdominal radiographs and 57 computed tomography (CT) scans, of which 51 were thoracic CT scans, were analysed. The average cumulative radiation dose was 6.2 (0.04-25) mSv per CF patient. Cumulative radiation dose increased with increasing age and number of CT scans and was greater in children who presented with meconium ileus. No correlation was identified between cumulative radiation dose and either lung function or patient microbiology cultures. Radiation carries a risk of malignancy and children are particularly susceptible. Every effort must be made to avoid unnecessary radiation exposure in these patients whose life expectancy is increasing.

    Maternal psychological stress during pregnancy has essentially been conceptualized as a teratogen. However, little is known about the effect of temperature on maternal stress during pregnancy. The aim of this study is to investigate the relationship between temperature and maternal stress during pregnancy. In 2010, a total of 1931 eligible pregnant women were enrolled across Shanghai from four prenatal-care clinics during their mid-to-late pregnancy. Maternal life-event stress and emotional stress levels during pregnancy were assessed by the "Life Event Scale for Pregnant Women" (LESPW) and "Symptom Checklist-90-Revised Scale" (SCL-90-R), respectively. Exposure to ambient temperature was evaluated based on daily regional average in different moving average and lag days. The generalized estimating equations were used to evaluate the relationship between daily average temperature/temperature difference and maternal stress. After adjusting for relevant confounders, an U-shaped relationship was observed between daily average temperature and maternal Global-Severity-Index (GSI) of the SCL-90-R.

    Internet search queries have become an important data source in syndromic surveillance system. However, there is currently no syndromic surveillance system using Internet search query data in South Korea. The objective of this study was to examine correlations between our cumulative query method and national influenza surveillance data. Our study was based on the local search engine, Daum (approximately 25% market share), and influenza-like illness (ILI) data from the Korea Centers for Disease Control and Prevention. A quota sampling survey was conducted with 200 participants to obtain popular queries. We divided the study period into two sets: Set 1 (the 2009/10 epidemiological year for development set 1 and 2010/11 for validation set 1) and Set 2 (2010/11 for development Set 2 and 2011/12 for validation Set 2). Pearson's correlation coefficients were calculated between the Daum data and the ILI data for the development set. We selected the combined queries for which the correlation coefficients were .7 or higher and listed them in descending order. Then, we created a cumulative query method n representing the number of cumulative combined queries in descending order of the correlation coefficient. In validation set 1, 13 cumulative query methods were applied, and 8 had higher correlation coefficients (min=.916, max=.943) than that of the highest single combined query. Further, 11 of 13 cumulative query methods had an r value of ≥.7, but 4 of 13 combined queries had an r value of ≥.7. In validation set 2, 8 of 15 cumulative query methods showed higher correlation coefficients (min=.975, max=.987) than that of the highest single combined query. All 15 cumulative query methods had an r value of ≥.7, but 6 of 15 combined queries had an r value of ≥.7. Cumulative query method showed relatively higher correlation with national influenza surveillance data than combined queries in the development and validation set.

    Occupational exposure limits have traditionally focused on preventing morbidity and mortality arising from inhalation exposures to individual chemical stressors in the workplace. While central to occupational risk assessment, occupational exposure limits have limited application as a refined disease prevention tool because they do not account for all of the complexities of the work and non-occupational environments and are based on varying health endpoints. To be of greater utility, occupational exposure limits and other risk management tools could integrate broader consideration of risks from multiple exposure pathways and routes (aggregate risk) as well as the combined risk from exposure to both chemical and non-chemical stressors, within and beyond the workplace, including the possibility that such exposures may cause interactions or modify the toxic effects observed (cumulative risk). Although still at a rudimentary stage in many cases, a variety of methods and tools have been developed or are being used in allied risk assessment fields to incorporate such considerations in the risk assessment process. These approaches, which are collectively referred to as cumulative risk assessment, have potential to be adapted or modified for occupational scenarios and provide a tangible path forward for occupational risk assessment. Accounting for complex exposures in the workplace and the broader risks faced by the individual also requires a more complete consideration of the composite effects of occupational and non-occupational risk factors to fully assess and manage worker health problems. Barriers to integrating these different factors remain, but new and ongoing community-based and worker health-related initiatives may provide mechanisms for identifying and integrating risk from aggregate exposures and cumulative risks from all relevant sources, be they occupational or non-occupational.

    The objective of this review was to conduct a meta-analysis of all up-to-date randomised control trials to determine whether periodontal treatment during pregnancy has the potential of reducing preterm birth and low birth weight incidence. Bibliographic databases MEDLINE (1966-present), EMBASE (1980-present), CINAHL (1982-present) and the Cochrane library up to and including 2010 Issue 10 were searched. The reference list of included studies and reviews were also searched for additional literature. Eligible studies were, published and ongoing randomised control trials that compared pregnancy outcomes for pregnant women who received periodontal treatment during the prenatal period. Two of the investigators independently assessed the studies and then extracted and summarised data from eligible trials. Extracted data were entered into Review Manager software and analysed. A total of 5645 pregnant women participated in the 10 eligible trials. Meta-analysis found that periodontal treatment significantly lowered preterm birth (odd ratio 0.65; 95% confidence interval, 0.45-0.93; P = 0.02) and low birth weight (odd ratio 0.53; 95% confidence interval, 0.31-0.92; P = 0.02) rates while no significant difference was found for spontaneous abortion/stillbirth (odd ratio 0.71; 95% confidence interval, 0.43-1.16; P = 0.17). Moderate heterogeneity was observed among the studies for preterm birth and low birth weight. Subgroup analysis showed significant effect of periodontal treatment in pregnant women with low rate of previous preterm birth/low birth weight (odd ratio 0.35; 95% confidence interval, 017-0.70; P = 0.003) and less severe periodontal disease (odd ratio 0.49; confidence interval, 028-0.87; P = 0.01) as defined by probing depth. The cumulative evidence suggests that periodontal treatment during pregnancy may reduce preterm birth and low birth weight incidence. However, these findings need to be further validated through larger more targeted randomised control trials.

    The Weathering Effect is a theory that links stress exposure, over the life-course, with racial disparities in reproductive outcomes, through the effects of social adversity on a woman's body. The concept of maternal "weathering" captures cumulative somatic and psychological adversities that can exacerbate the effects of aging. Much of the evidence for weathering comes from observational studies linking self-report measures with reproductive outcomes. The purpose of this review is to explore biological mechanisms that underlie these observations. We focus on spontaneous abortion because this event is understudied despite evidence of racial disparities in this outcome. Spontaneous abortion is the most common pregnancy failure, and it happens early in pregnancy. Early pregnancy is a time most susceptible to the harmful effects of immune dysregulation that may, in part, result from adversities experienced before pregnancy begins. In exploring these mechanisms, we draw on well-defined signaling processes observed in the stressor-depression relationship. Pro-inflammatory dysregulation, for example, has particular relevance to immunological control occurring early in pregnancy. Early pregnancy immunologic changes affect the trajectories of pregnancy via control of trophoblastic invasion. Within the first few weeks of pregnancy, uterine derived cytokines operate within cytokine networks and play a critical role in this invasion. Programming for pro-inflammatory dysregulation can occur before conception. This dysregulation, brought into early pregnancy, has implications for viability and success of the index pregnancy. These patterns suggest early pregnancy health is susceptible to stress processing pathways that influence this immunologic control in the first six to eight weeks of pregnancy. In this review, we discuss the known mediating role of immune factors in the stressor-depression relationship. We also discuss how adversity experienced before the index pregnancy, or

This review consolidates previously published findings from our group in order to compare and contrast the spatial profile of neural activity coherence across these distinct cortical dimensions. We focus on studies of ongoing local field potential (LFP data obtained simultaneously from multiple sites in the primary visual cortex in two types of experiments in which electrode contacts were spaced either along the cortical surface or at different laminar positions. These studies demonstrate that across both dimensions the coherence of ongoing LFP fluctuations diminishes as a function of interelectrode distance, although the nature and spatial scale of this falloff is very different. Along the cortical surface, the overall LFP coherence declines gradually and continuously away from a given position. In contrast, across the cortical layers, LFP coherence is discontinuous and compartmentalized as a function of depth. Specifically, regions of high LFP coherence fall into discrete superficial and deep laminar zones, with an abrupt discontinuity between the granular and infragranular layers. This spatial pattern of ongoing LFP coherence is similar when animals are at rest and when they are engaged in a behavioral task. These results point to the existence of partially segregated laminar zones of cortical processing that extend tangentially within the laminar compartments and are thus oriented orthogonal to the cortical columns. We interpret these electrophysiological observations in light of the known anatomical organization of

    Full Text Available Abnormal liver function tests occur in 3-5% of pregnancies, with many potential causes, including coincidental liver disease (most commonly viral hepatitis or gallstones and underlying chronic liver disease. Pruritus in pregnancy is common, affecting 23% of pregnancies, of which a small proportion will have obstetric cholestasis. Intrahepatic cholestasis of pregnancy (ICP is a cholestatic disorder characterized by pruritus with onset in the second or third trimester of pregnancy, elevated serum aminotransferases and bile acid levels, and spontaneous relief of signs and symptoms within two to three weeks after delivery. ICP is observed in 0.4-1% of pregnancies in most areas of Central and Western Europe and North America. Genetic and hormonal factors, but also environmental factors may contribute to the pathogenesis of ICP. Intrahepatic cholestasis of pregnancy increases the risk of preterm delivery (19­60%, meconium staining of amniotic fluid (27%, fetal bradycardia (14%, fetal distress (22-41%, and fetal loss (0.4-4.1%, particularly when associated with fasting serum bile acid levels >40 μmol/L. Important ICP-induced changes in serum profiles of amidated bile acids were observed, involving both a marked increase in cholic acid concentration and a shift towards a higher proportion of taurine-conjugated species. Ursodeoxycholic acid (10-20 mg/kg/d is today regarded as the first line treatment for intrahepatic cholestasis of pregnancy. Delivery has been recommended in the 37-38th week when lung maturity has been established.

  4. PREGNANCY AND THYROID

    Directory of Open Access Journals (Sweden)

    Simona Gaberšček

    2004-01-01

    Full Text Available Background. In conditions with appropriate iodine intake, thyroid gland adapts to changes during pregnancy without any consequences. Fetal need for thyroid hormones in the first trimester is directly connected with transplacental transport of thyroid hormones. Fetal synthesis of thyroid hormones depends on availability of iodine in the feto-placental unit. Hypo- and hyperthyroidism during pregnancy are risk factors for pregnant woman and for normal development of fetus and child.Conclusions. Pregnant women with appropriately treated thyroid diseases have the same outcome of pregnancy as healthy women, and neuroendocrinological development of children is not impaired. If the disease is unrecognized or untreated, complications of pregnancy and delivery occur more frequently. Therefore, timely recognition and treatment of the diseases with appropriate drugs during pregnancy and, also, after delivery is very important.

  5. Heterotopic pregnancy: Sonographic findings

    1999-01-01

    To evaluate the sonographic findings of the heterotopic pregnancy which is increasing recently. Thirty-nine cases of heterotopic pregnancy after ovulation induction and IVF-ET (In Vitro Fertilization-Embryo Transfer) during the recent 3 years were analyzed. They were diagnosed by ultrasonography and proved surgically afterwards. Sonographic findings were analyzed focusing on gestational week of intrauterine pregnancy and location of ectopic pregnancy. In particular, adnexal mass was evaluated with regard to size and the characteristic findings such as ectopic gestational sac (echogenic ring). Also, overian cyst and fluid collection in cul-de-sac space were reviewed carefully. Heterotopic pregnancy was proved surgically by salpingectomy in 33 cases and by resection of cornus in six cases. Sonographic diagnosis using transvaginal ultrasound was made from five weeks to nine weeks two days (six weeks and four days in average) from last menstral period in all 39 cases. Ectopic pregnancy was identified in ampullary part in 29 cases, in the isthmic portion of tube in four cases and in the cornus of uterus in six cases. The intrauterine pregnancy was diagnosed by identifying the intrauterine gestational saccontaining a yolk sac in seven cases and the embryo with fetal heart beat in the remaining 32 cases. Adnexal masses of heterotopic pregnancy were less than 3 cm in diameter in 2 cases (57%), 3-4 cm in 11 cases (28%) and more than 4 cm in 6 cases (15%). A characteristic finding of ectopic mass was echogenic ring which was visible in 33 (84.6%) cases by transvaginal ultrasound. Six cases had pelvic hematosalpinx and two had pelvic hematoma. Of 10 cases (26%) which were identified to have ovarian hyperstimulation syndrome, eight (21%) had large amount of fluid collection in cul-de-sac and abdomen. Ultrasonographic identification of the intrauterine pregnancy and the ectopic chorion ring is effective for the early diagnosis of the heterotopic pregnancy.

  6. Suspected ectopic pregnancy.

    Women who present with pain and bleeding in the first trimester are at risk for ectopic pregnancy, a life-threatening condition. Conditions that predispose a woman to ectopic pregnancy are damaged fallopian tubes from prior tubal surgery or previous pelvic infection, smoking, and conception using assisted reproduction. Many women without risk factors can develop an ectopic pregnancy. A diagnostic algorithm that includes the use of transvaginal ultrasonography, human chorionic gonadotropin (hCG) concentrations, and, sometimes, uterine curettage can definitively diagnose women at risk in a timely manner. The absence of an intrauterine pregnancy above an established cut point of hCG is consistent with an abnormal pregnancy but does not distinguish a miscarriage from an ectopic pregnancy. When the initial hCG value is low, serial hCG values can be used to determine whether a gestation is potentially viable or spontaneously resolving. The minimal rise in hCG for a viable pregnancy is 53% in 2 days. The minimal decline of a spontaneous abortion is 21-35% in 2 days, depending on the initial level. A rise or fall in serial hCG values that is slower than this is suggestive of an ectopic pregnancy. Women diagnosed with an unruptured ectopic pregnancy are potential candidates for medical management with methotrexate. Intramuscular injection with methotrexate can be used to safely treat an ectopic pregnancy with success rates, tubal patency rates, and future fertility that are similar to those obtained with conservative surgery. Success rates using methotrexate are inversely rated to baseline hCG values and are higher using "multidose" compared with "single-dose" regimens. Surgical treatment may be conservative or definitive and should be attempted in most cases via laparoscopy.

    Full Text Available BACKGROUND Thyroid diseases and diabetes mellitus are the most common endocrine diseases during pregnancy. Internal Medicine doctors could be involved in the management of pregnant women affected by thyroid diseases, in particular if an Endocrine Unit lacks in the hospital; it is mandatory that they have the skills to cope with these diseases. METHODS In this work authors describe the most common thyroid abnormalities that can occur during pregnancy: hypothyroidism (clinical and subclinical, hyperthyroidism (clinical and sub-clinical, autoimmune thyroiditis (in particular the so called post-partum thyroiditis, nodular diseases and cancer. They discuss moreover the peculiar pathophysiologic mechanisms by which these diseases appear, the diagnostic tools and the therapies, according to their own experience and the more recent international guidelines. RESULTS AND CONCLUSIONS It is important to evaluate thyroid function tests before and during pregnancy, at 16th and 28th gestational week; it is mandatory to cure also the “sub-clinical” hypothyroidism during pregnancy, when TSH level are higher than 5 μIU/mL; the optimal dose of levo-thyroxine during pregnancy is, average, 30-50% higher than that used before pregnancy; it is not correct to treat mild or sub-clinical hyperthyroidism; propylthyouracil is the best drug to treat hyperthyroidism during pregnancy; the post-partum thyroiditis is generally transient, so that a careful monitoring of thyroid function is advisable, in particular after 9-12 months of therapy; thyroid cancer, if discovered during pregnancy, generally has no negative effects on the outcome of the pregnancy; it would be better to treat surgically thyroid cancer during the last trimester of the pregnancy.

    Full Text Available The Rare Cancer Network (RCN was formed in the early 1990’s to create a global network that could pool knowledge and resources in the studies of rare malignancies whose infrequency prevented both their study with prospective clinical trials. To date, the RCN has initiated 74 studies resulting in 46 peer reviewed publications. The First International Symposium of the Rare Cancer Network took place in Nice in March of 2014. Status updates and proposals for new studies were heard for fifteen topics. Ongoing studies continue for cardiac sarcomas, thyroid cancers, glomus tumors, and adult medulloblastomas. New proposals were presented at the symposium for primary hepatic lymphoma, solitary fibrous tumors, Rosai-Dorfman disease, tumors of the ampulla of Vater, salivary gland tumors, anorectal melanoma, midline nuclear protein in testes carcinoma, pulmonary lymphoepithelioma-like carcinoma, adenoid cystic carcinoma of the trachea, osteosarcomas of the mandible, and extra-cranial hemangiopericytoma. This manuscript presents the abstracts of those proposals and updates on ongoing studies, as well a brief summary of the vision and future of the RCN.

    Neurons in the primary visual cortex spontaneously spike even when there are no visual stimuli. It is unknown whether the spiking evoked by visual stimuli is just a modification of the spontaneous ongoing cortical spiking dynamics or whether the spontaneous spiking state disappears and is replaced by evoked spiking. This study of laminar recordings of spontaneous spiking and visually evoked spiking of neurons in the ferret primary visual cortex shows that the spiking dynamics does not change: the spontaneous spiking as well as evoked spiking is controlled by a stable and persisting fixed point attractor. Its existence guarantees that evoked spiking return to the spontaneous state. However, the spontaneous ongoing spiking state and the visual evoked spiking states are qualitatively different and are separated by a threshold (separatrix). The functional advantage of this organization is that it avoids the need for a system reorganization following visual stimulation, and impedes the transition of spontaneous spiking to evoked spiking and the propagation of spontaneous spiking from layer 4 to layers 2–3.

    2012-02-01

    BACKGROUND: Azathioprine (AZA) is used during pregnancy by women with inflammatory bowel disease (IBD), other autoimmune disorders, malignancy, and organ transplantation. Previous studies have demonstrated potential risks. METHODS: The Swedish Medical Birth Register was used to identify 476 women who reported the use of AZA in early pregnancy. The effect of AZA exposure on pregnancy outcomes was studied after adjustment for maternal characteristics that could act as confounders. RESULTS: The most common indication for AZA use was IBD. The rate of congenital malformations was 6.2% in the AZA group and 4.7% among all infants born (adjusted OR: 1.41, 95% CI: 0.98-2.04). An association between early pregnancy AZA exposure and ventricular\\/atrial septal defects was found (adjusted OR: 3.18, 95% CI: 1.45-6.04). Exposed infants were also more likely to be preterm, to weigh <2500 gm, and to be small for gestational age compared to all infants born. This effect remained for preterm birth and low birth weight when infants of women with IBD but without AZA exposure were used as a comparison group. A trend toward an increased risk of congenital malformations was found among infants of women with IBD using AZA compared to women with IBD not using AZA (adjusted OR: 1.42, 95% CI: 0.93-2.18). CONCLUSIONS: Infants exposed to AZA in early pregnancy may be at a moderately increased risk of congenital malformations, specifically ventricular\\/atrial septal defects. There is also an increased risk of growth restriction and preterm delivery. These associations may be confounded by the severity of maternal illness.

  13. Pregnancy: an immune challenge

    Directory of Open Access Journals (Sweden)

    Maria Angelica Ehara Watanabe

    2014-12-01

    Full Text Available Several studies demonstrate the importance of immunological aspects of pregnancy. During pregnancy, the embryo is implanted in the womb, where it will develop until the end of pregnancy. Amongst the immune aspects, the importance of the modulation of T lymphocytes, natural killers (NK cells and many cytokines in maternal organism can be mentioned. The maternal tolerance to the fetus appears to be mediated by specific maternal hormones and by the expression of human leukocyte antigen G (HLA-G - characteristic in pregnancy. Other studies suggest that fetal rejection and complications during pregnancy may occur because of the presence of minor histocompatibility antigens (mHAg, acquired by blood sharing of the mother with the fetus, and because of the presence of maternal antibodies against the sperm and against the fetus. The purpose of this review is to describe the immunological aspects that allow maternal tolerance to the fetus during pregnancy, as well as possible causes for rejection of the embryo and complications during pregnancy.

  14. Hyperthyroidism in pregnancy.

    Mestman, Jorge H

    2012-10-01

    Successful outcome in pregnancy hyperthyroidism depends on the cause, interpretation of laboratory tests, and careful use of antithyroid drug (ATD) therapy. Planning of a pregnancy in a woman with active or past history of Graves' hyperthyroidism is mandatory in order to avoid complications. Fetal health may be affected by three factors: poor control of maternal hyperthyroidism, titer of maternal TRAb, and inappropriate use of ATD. Careful assessment of thyroid function through pregnancy and evaluation of fetal development by ultrasonography is the cornerstone for a successful outcome. In a subgroup of women previously treated with ablation therapy, those whose serum TSRAb titers remained elevated, are at risk of having a fetus/neonate with Graves' hyperthyroidism. Use of ATD during lactation is well tolerated, if recommended guidelines are followed. Women during their childbearing age with active Graves' hyperthyroidism should plan their pregnancy. Causes of hyperthyroidism in pregnancy include Graves' disease or autonomous adenoma, and transient gestational thyrotoxicosis as a consequence of excessive production of human chroionic gonadotropin by the placenta. Careful interpretation of thyroid function tests and frequent adjustment of ATD is of utmost importance in the outcome of pregnancy. Graves' hyperthyroidism may relapse early in pregnancy or at the end of the first year postpartum.

    2012-02-01

    Anaemia in pregnancy, defined as a haemoglobin concentration (Hb) anaemia in pregnancy, nutritional iron deficiency anaemia (IDA) being the commonest. Underlying inflammatory conditions, physiological haemodilution and several factors affecting Hb and iron status in pregnancy lead to difficulties in establishing a definitive diagnosis. IDA is associated with increased maternal and perinatal morbidity and mortality, and long-term adverse effects in the new born. Strategies to prevent anaemia in pregnancy and its adverse effects include treatment of underlying conditions, iron and folate supplementation given weekly for all menstruating women including adolescents and daily for women during pregnancy and the post partum period, and delayed clamping of the umbilical cord at delivery. Oral iron is preferable to intravenous therapy for treatment of IDA. B12 and folate deficiencies in pregnancy are rare and may be due to inadequate dietary intake with the latter being more common. These vitamins play an important role in embryo genesis and hence any relative deficiencies may result in congenital abnormalities. Finding the underlying cause are crucial to the management of these deficiencies. Haemolytic anaemias rare also rare in pregnancy, but may have life-threatening complications if the diagnosis is not made in good time and acted upon appropriately. Copyright © 2011 Elsevier Ltd.

    2010-10-01

    Hemodialysis is associated with an increased risk of neoplasms which may result, at least in part, from exposure to ionizing radiation associated with frequent radiographic procedures. In order to estimate the average radiation exposure of those on hemodialysis, we conducted a retrospective study of 100 patients in a university-based dialysis unit followed for a median of 3.4 years. The number and type of radiological procedures were obtained from a central radiology database, and the cumulative effective radiation dose was calculated using standardized, procedure-specific radiation levels. The median annual radiation dose was 6.9 millisieverts (mSv) per patient-year. However, 14 patients had an annual cumulative effective radiation dose over 20 mSv, the upper averaged annual limit for occupational exposure. The median total cumulative effective radiation dose per patient over the study period was 21.7 mSv, in which 13 patients had a total cumulative effective radiation dose over 75 mSv, a value reported to be associated with a 7% increased risk of cancer-related mortality. Two-thirds of the total cumulative effective radiation dose was due to CT scanning. The average radiation exposure was significantly associated with the cause of end-stage renal disease, history of ischemic heart disease, transplant waitlist status, number of in-patient hospital days over follow-up, and death during the study period. These results highlight the substantial exposure to ionizing radiation in hemodialysis patients.

    Full Text Available Abstract Background The registration of clinical trials has been promoted to prevent publication bias and increase research transparency. Despite general agreement about the minimum amount of information needed for trial registration, we lack clear guidance on descriptions of non-pharmacologic interventions in trial registries. We aimed to evaluate the quality of registry descriptions of non-pharmacologic interventions assessed in ongoing randomized controlled trials (RCTs of patient education. Methods On 6 May 2009, we searched for all ongoing RCTs registered in the 10 trial registries accessible through the World Health Organization International Clinical Trials Registry Platform. We included trials evaluating an educational intervention (that is, designed to teach or train patients about their own health and dedicated to participants, their family members or home caregivers. We used a standardized data extraction form to collect data related to the description of the experimental intervention, the centers, and the caregivers. Results We selected 268 of 642 potentially eligible studies and appraised a random sample of 150 records. All selected trials were registered in 4 registers, mainly ClinicalTrials.gov (61%. The median [interquartile range] target sample size was 205 [100 to 400] patients. The comparator was mainly usual care (47% or active treatment (47%. A minority of records (17%, 95% CI 11 to 23% reported an overall adequate description of the intervention (that is, description that reported the content, mode of delivery, number, frequency, duration of sessions and overall duration of the intervention. Further, for most reports (59%, important information about the content of the intervention was missing. The description of the mode of delivery of the intervention was reported for 52% of studies, the number of sessions for 74%, the frequency of sessions for 58%, the duration of each session for 45% and the overall duration for 63

Significant findings: The patient’s serum beta-hCG was 5,637 mIU/mL. The transvaginal ultrasound showed an empty uterus with free fluid posteriorly in the pelvis and Pouch of Douglas (00:00. A 4.5 cm heterogeneous mass was visible in the left adnexa concerning for an ectopic pregnancy (00:10. Discussion: Ectopic pregnancies are a leading cause of maternal morbidity and mortality, as well as decreased fertility.1,2 Differentiating between an ectopic pregnancy and a normal early pregnancy may be difficult, since ultrasound and quantitative beta-hCG may show inconclusive results.3,4 Patients who have used fertility treatment may further complicate the picture because they are at risk for heterotypic pregnancies.5 Ectopic pregnancies most commonly implant in the fallopian tube, but may alternatively implant in the ovary, cervix, abdomen, or uterine cornua.4 Ultrasonography may show an empty uterus, adnexal mass, pelvic free fluid, or an extra-uterine gestational sac, yolk sac, and/or embryo.6 Treatment options for ectopic pregnancy include surgery or methotrexate.2,4 Some patients may be candidates for close outpatient surveillance if the diagnosis is unclear or in very limited cases for early, non-ruptured ectopic pregnancies.2,4

    , but more than 50% of stillbirths are unexplained. Majority of stillbirths are characterised by suboptimal glycaemic control during pregnancy. Foetal hypoxia and cardiac dysfunction secondary to poor glycaemic control are probably the most important pathogenic factors in stillbirths among pregnant diabetic...... women. There is thus a need for new strategies for improving glycaemic control to near-normal levels throughout pregnancy and for preventing and treating hypertensive disorders in pregnancy.

    Background: Coffee consumption in Denmark is high also among pregnant women and it is presumably their main source of caffeine intake. Coffee or caffeine intake during pregnancy has been linked to adverse pregnancy outcomes such as spontaneous abortion, stillbirth and reduced fetal growth. However...... a review of the literature indicates that further studies are needed to test the hypothesis of an effect of coffee or caffeine on the risk of adverse pregnancy outcomes.The aim of the thesis was to study the relation between coffee and the risk of fetal death and the relation between caffeine intake...

    Fournier gangrene is a rare and rapidly progressive necrosis of the perineal and genitourinary region. Although predominantly affecting men, we describe an unusual presentation in pregnancy. A 30-year old primigravid woman in the third trimester of pregnancy presented with a history of low back pain. Subsequently, a diagnosis of perianal sepsis and associated Fournier gangrene was established. The patient underwent an emergency cesarean delivery followed by radical surgical debridement and colostomy. Expedited delivery, timely diagnosis of gangrene, urgent, extensive debridement, and broad-spectrum antibiotic coverage contributed largely to effective management of this rare presentation in pregnancy.

    Pregnancy occurs rarely in patients with Cushing syndrome (CS) due to hypercortisolism. So far, about 150 cases of CS in pregnancy have been reported in the literature. We describe a 22-year-old female who presented in pregnancy with clinical features of CS. She delivered at 34 weeks of gestation and baby had transient adrenal insufficiency in the neonatal period. Mother underwent transsphenoidal surgery 1 year postpartum and on follow up she is under remission. Neonatal hypoadrenalism should be anticipated in maternal CS.

    CONTEXT The extent to which pregnancy intentions mediate the relationship between individual, familial and cultural characteristics and adolescent pregnancy is not well understood. The role of intentions may be particularly important among Latina teenagers, whose attitudes toward pregnancy are more favorable than those of other groups and whose pregnancy rates are high. METHODS Prospective, time-varying data from 2001–2004 were used to investigate whether two measures of pregnancy intentions, wantedness and happiness, mediated associations between risk factors and pregnancy among 213 Latina adolescents in San Francisco. Participants were tested for pregnancy and interviewed about pregnancy intentions, partnerships, family characteristics and activities every six months for two years. Associations and mediation were examined using logistic regression. RESULTS Neither pregnancy intention variable mediated relationships between participant characteristics and pregnancy. After adjustment for other measures, wantedness was strongly associated with pregnancy (odds ratio, 2.6), while happiness was not. Having a strong family orientation was associated with happiness (3.7) but unrelated to pregnancy. Low sexual relationship power with a main partner was associated with an elevated risk of pregnancy (3.3). If the pregnancy intentions of all participants were changed to definitely not wanting pregnancy, the estimated decline in pregnancy risk would be 16%. CONCLUSIONS Pregnancy intentions were important not as mediators but rather as independent risk factors for pregnancy. Differences in pregnancy rates between groups of Latinas may be less a function of intentional choice than of situational factors. Interventions and research should focus on identifying and targeting factors that hinder effective contraceptive use among teenagers who want to avoid pregnancy. PMID:20887287

    2007-03-01

    This paper presents the findings of a study commissioned by World Food Programme (WFP) in early 2006 to enhance understanding of how the conflict in Darfur has affected livelihoods and markets, and of the effects of food aid. The livelihoods of many in Darfur were devastated early on in the conflict, principally through the widespread looting or destruction of assets and highly restricted population movements, which struck at the heart of pre-conflict livelihoods. Livelihood strategies for most people are now restricted, poorly remunerated and often associated with high risk of attack. Patterns of coercion and exploitation have also become entrenched; and markets and trade, the lifeblood of Da fur's economy pre-conflict, severely disrupted. Against this backdrop the impact of food aid on livelihoods in Darfur has been overwhelmingly positive. The paper proposes a number of preconditions for investment in recovery in Darfur, and recommends ways in which livelihoods can be supported in the current context of ongoing conflict.

  7. Striking an interim balance of the ongoing climate debate

    After the Berlin UN conference of the signatory states to the Climate Change Convention it seems appropriate to strike an interim balance of the ongoing debate about the global climate change, as it has meanwhile evolved from an issue discussed among experts to an issue of public debate. Such a ''progress report'' seems to be opportune also because doubts are mounting in the face of proclaimed countermeasures. The article therefore reviews and summarizes facts and figures, discussing emissions and concentrations, the physical properties of greenhouse gases, as well as uncertainties of model calculations and of interpretations of measured data. The current situation calls for application of alternative models and concepts, and consideration of natural processes in competition with man-made impacts on the climate within the framework of optimized interpretation, in order to have probabilistic data at hand for decision-making.

    We present updated results from our ongoing analysis of Cassini observations of Jupiter's equatorial meteorology. For two months preceding the spacecraft's closest approach of the planet, the ISS instrument onboard Cassini regularly imaged the atmosphere of Jupiter. We created time-lapse movies from this period that show the complex activity and interactions of the equatorial atmosphere. During this period, hot spots exhibited significant variations in size and shape over timescales of days and weeks. Some of these changes appear to be a result of interactions with passing vortex systems in adjacent latitudes. Strong anticyclonic gyres to the southeast of the dark areas converge with flow from the west and appear to circulate into a hot spot at its southwestern corner.

    U.S. Gulf Coast salt domes, among other geologic structures, currently are being considered for storage of commercial radioactive wastes. A major concern with dome storage of long lived radioactive wastes lies with the possible tectonic movement of the host dome. Any ongoing movement of a salt dome can be monitored with a site specific complementary system of field instrumentation and finite element modelling. Field instrumentation and accompanying finite element analyses for a study dome in northwest Louisiana are described. Site specific data and early experience associated with tiltmeters over the dome are presented. Also, recommendations are made for modifications and extensions of the field instrumentation and finite element modelling appropriate to the specific site under study

    2005-08-01

    The aim of this study was to evaluate the short-term impact of a group crisis intervention for children aged 9-15 years from five refugee camps in the Gaza Strip during ongoing war conflict. Children were selected if they reported moderate to severe posttraumatic stress reactions, and were allocated to group intervention (N=47) encouraging expression of experiences and emotions through storytelling, drawing, free play and role-play; education about symptoms (N=22); or no intervention (N=42). Children completed the CPTSD-RI and the CDI pre- and post-intervention. No significant impact of the group intervention was established on children's posttraumatic or depressive symptoms. Possible explanations of the findings are discussed, including the continuing exposure to trauma and the non-active nature of the intervention.

  11. Energy Colonialism Powers the Ongoing Unnatural Disaster in Puerto Rico

    2018-01-01

    Full Text Available On September 20, 2017, Hurricane María made landfall in Puerto Rico. Blasting the Caribbean archipelago with 155-mile/h winds, this, in many ways, unnatural disaster exposed the brutal consequences of energy colonialism and an extractivist economy, as well as ongoing and increasing advocacy for decentralized solar infrastructure by many local residents and other renewables supporters. This paper argues that acknowledging colonial power relations and their consequences is essential for studying the interplay of energy systems, environments, and actors. To support this claim, this essay outlines Puerto Rico’s history as a US colony by focusing on key policies and their implications; examines openings for and barriers to decentralized, community solar in Puerto Rico; and concludes by discussing future research directions on just energy transitions and the imperative of uprooting colonialism and agitating for community self-determination and energy justice in these transformations.

    The aim of this study was to present the development, structure and results of a database on planned and ongoing health technology assessment (HTA) projects (POP Database) in Europe. The POP Database (POP DB) was set up in an iterative process from a basic Excel sheet to a multifunctional electronic online database. The functionalities, such as the search terminology, the procedures to fill and update the database, the access rules to enter the database, as well as the maintenance roles, were defined in a multistep participatory feedback loop with EUnetHTA Partners. The POP Database has become an online database that hosts not only the titles and MeSH categorizations, but also some basic information on status and contact details about the listed projects of EUnetHTA Partners. Currently, it stores more than 1,200 planned, ongoing or recently published projects of forty-three EUnetHTA Partners from twenty-four countries. Because the POP Database aims to facilitate collaboration, it also provides a matching system to assist in identifying similar projects. Overall, more than 10 percent of the projects in the database are identical both in terms of pathology (indication or disease) and technology (drug, medical device, intervention). In addition, approximately 30 percent of the projects are similar, meaning that they have at least some overlap in content. Although the POP DB is successful concerning regular updates of most national HTA agencies within EUnetHTA, little is known about its actual effects on collaborations in Europe. Moreover, many non-nationally nominated HTA producing agencies neither have access to the POP DB nor can share their projects.

    Full Text Available BACKGROUND: With the increasing prevalence of chronic noncommunicable diseases, patient education is becoming important to strengthen disease prevention and control. We aimed to systematically determine the extent to which registered, ongoing randomized controlled trials (RCTs evaluated an educational intervention focus on patient-important outcomes (i.e., outcomes measuring patient health status and quality of life. METHODS: On May 6, 2009, we searched for all ongoing RCTs registered in the World Health Organization International Clinical Trials Registry platform. We used a standardized data extraction form to collect data and determined whether the outcomes assessed were 1 patient-important outcomes such as clinical events, functional status, pain, or quality of life or 2 surrogate outcomes, such as biological outcome, treatment adherence, or patient knowledge. PRINCIPAL FINDINGS: We selected 268 of the 642 potentially eligible studies and assessed a random sample of 150. Patient-important outcomes represented 54% (178 of 333 of all primary outcomes and 46% (286 of 623 of all secondary outcomes. Overall, 69% of trials (104 of 150 used at least one patient-important outcome as a primary outcome and 66% (99 of 150 as a secondary outcome. Finally, for 31% of trials (46 of 150, primary outcomes were only surrogate outcomes. The results varied by medical area. In neuropsychiatric disorders, patient important outcomes represented 84% (51 of 61 of primary outcomes, as compared with 54% (32 of 59 in malignant neoplasm and 18% (4 of 22 in diabetes mellitus trials. In addition, only 35% assessed the long-term impact of interventions (i.e., >6 months. CONCLUSIONS: There is a need to improve the relevance of outcomes and to assess the long term impact of educational interventions in RCTs.

  15. Evidence-Responsiveness and the Ongoing Autonomy of Treatment Preferences.

    Science.gov (United States)

    Weimer, Steven

    2017-06-14

    To be an autonomous agent is to determine one's own path in life. However, this cannot plausibly be seen as a one-off affair. An autonomous agent does not merely set herself on a particular course and then lock the steering wheel in place, so to speak, but must maintain some form of ongoing control over her direction in life-must keep her eyes on the road and her hands on the wheel. Circumstances often change in important and unexpected ways, after all, and it is reasonable to think that a crucial part of autonomy consists of the ability and disposition to recognize and properly respond to such changes. This implies, I contend, that a patient whose initial decision to undergo a given treatment satisfied plausible requirements of autonomy, but who is now unable to recognize that available evidence indicates the need to reconsider her medical situation and options has come to lack autonomy with respect to her desire to continue that treatment. However, and despite its importance with respect to both theoretical understandings of autonomy and applications of the concept to clinical ethics, this ongoing aspect of autonomy has received little attention. This paper aims to go some way toward remedying that. I first critically review two of the few theories of autonomy that do address "evidence-responsiveness" so as to identify and elaborate what I take to be the most promising way in which to account for this aspect of autonomy. After considering and responding to a possible objection to the evidence-responsiveness condition I propose, I conclude by discussing its clinical implications. That condition, I argue, is not merely theoretically sound, but can and should be applied to clinical practice.

    2017-06-01

    Mayas, having experienced genocide, exile, and severe poverty, are at high risk for the consequences of cumulative trauma that continually resurfaces through current fear of an uncertain future. Little is known about the mental health and alcohol use status of this population. This correlational study explored t/he relationship of cumulative trauma as it relates to social determinants of health (years in the United States, education, health insurance status, marital status, and employment), psychological health (depression symptoms), and health behaviors (alcohol use) of 102 Guatemalan Mayas living in Southeast Florida. The results of this study indicated that, as specific social determinants of health and cumulative trauma increased, depression symptoms (particularly among women) and the risk for harmful alcohol use (particularly among men) increased. Identifying risk factors at an early stage before serious disease or problems are manifest provides room for early screening leading to early identification, early treatment, and better outcomes.

    This session at the Wind Energy and Birds/Bats workshop consisted of a panel discussion followed by a discussion/question and answer period. The panelists were Paul Kerlinger, Curry and Kerlinger, LLC, Al Manville, U.S. Fish and Wildlife Service, and Bill Kendall, US Geological Service. The panel addressed the potential cumulative impacts of wind turbines on bird and bat populations over time. Panel members gave brief presentations that touched on what is currently known, what laws apply, and the usefulness of population modeling. Topics addressed included which sources of modeling should be included in cumulative impacts, comparison of impacts from different modes of energy generation, as well as what research is still needed regarding cumulative impacts of wind energy development on bird and bat populations.

    Hansen, Stefan N; Overgaard, Morten; Andersen, Per K

    2017-01-01

    BACKGROUND: The risk of a disease or psychiatric disorder is frequently measured by the age-specific cumulative incidence. Cumulative incidence estimates are often derived in cohort studies with individuals recruited over calendar time and with the end of follow-up governed by a specific date...... by calendar time trends, the total sample Kaplan-Meier and Aalen-Johansen estimators do not provide useful estimates of the general risk in the target population. We present some alternatives to this type of analysis. RESULTS: We show how a proportional hazards model may be used to extrapolate disease risk...... estimates if proportionality is a reasonable assumption. If not reasonable, we instead advocate that a more useful description of the disease risk lies in the age-specific cumulative incidence curves across strata given by time of entry or perhaps just the end of follow-up estimates across all strata...

  19. Evolutionary neural network modeling for software cumulative failure time prediction

    Tian Liang; Noore, Afzel

    2005-01-01

    An evolutionary neural network modeling approach for software cumulative failure time prediction based on multiple-delayed-input single-output architecture is proposed. Genetic algorithm is used to globally optimize the number of the delayed input neurons and the number of neurons in the hidden layer of the neural network architecture. Modification of Levenberg-Marquardt algorithm with Bayesian regularization is used to improve the ability to predict software cumulative failure time. The performance of our proposed approach has been compared using real-time control and flight dynamic application data sets. Numerical results show that both the goodness-of-fit and the next-step-predictability of our proposed approach have greater accuracy in predicting software cumulative failure time compared to existing approaches

    2015-01-01

    Abstract Many studies have tried to explain spatial and temporal variations in biodiversity status of marine areas from a single-issue perspective, such as fishing pressure or coastal pollution, yet most continental seas experience a wide range of human pressures. Cumulative impact assessments have...... been developed to capture the consequences of multiple stressors for biodiversity, but the ability of these assessments to accurately predict biodiversity status has never been tested or ground-truthed. This relationship has similarly been assumed for the Baltic Sea, especially in areas with impaired...... status, but has also never been documented. Here we provide a first tentative indication that cumulative human impacts relate to ecosystem condition, i.e. biodiversity status, in the Baltic Sea. Thus, cumulative impact assessments offer a promising tool for informed marine spatial planning, designation...

  2. Cumulative carbon as a policy framework for achieving climate stabilization

    Science.gov (United States)

    Matthews, H. Damon; Solomon, Susan; Pierrehumbert, Raymond

    2012-01-01

    The primary objective of the United Nations Framework Convention on Climate Change is to stabilize greenhouse gas concentrations at a level that will avoid dangerous climate impacts. However, greenhouse gas concentration stabilization is an awkward framework within which to assess dangerous climate change on account of the significant lag between a given concentration level and the eventual equilibrium temperature change. By contrast, recent research has shown that global temperature change can be well described by a given cumulative carbon emissions budget. Here, we propose that cumulative carbon emissions represent an alternative framework that is applicable both as a tool for climate mitigation as well as for the assessment of potential climate impacts. We show first that both atmospheric CO2 concentration at a given year and the associated temperature change are generally associated with a unique cumulative carbon emissions budget that is largely independent of the emissions scenario. The rate of global temperature change can therefore be related to first order to the rate of increase of cumulative carbon emissions. However, transient warming over the next century will also be strongly affected by emissions of shorter lived forcing agents such as aerosols and methane. Non-CO2 emissions therefore contribute to uncertainty in the cumulative carbon budget associated with near-term temperature targets, and may suggest the need for a mitigation approach that considers separately short- and long-lived gas emissions. By contrast, long-term temperature change remains primarily associated with total cumulative carbon emissions owing to the much longer atmospheric residence time of CO2 relative to other major climate forcing agents.

    2016-11-01

    To investigate whether antinuclear autoantibodies (ANA) could be related to the outcome of the successive pregnancy in women with unexplained recurrent miscarriage (uRM). Circulating ANA were measured by indirect immunofluorescence in 86 women with uRM before pregnancy, repeated in the first trimester of the successive gestation and correlated with pregnancy outcome. Forty-one women were ANA- and 45 were ANA+ before pregnancy. No relation was found between pre-pregnancy ANA status and the outcome of the successive pregnancy. However, when these women were monitored at 7th week during their pregnancy for ANA, of the 22 ANA+ women who remained ANA+ seven miscarriages (31.8%) were observed, whereas all of the 23 ANA+ women who became ANA- had pregnancies ongoing beyond the 20th week without miscarriage. ANA status could have a role in uRM. Disappearance of ANA in early pregnancy could have a favorable prognostic value in the successive pregnancy. © 2016 John Wiley & Sons A/S.

    The physical meaning and the combinatorial implications of the factorial cumulant of a state variable such as the number of neutrons or the number of neutron counts are specified. Features of the presentation are: (1) the fission process is treated in its entirety without the customary binary emission restriction, (b) the introduction of the factorial cumulants helps in reducing the complexity of the mathematical problems, (c) all the solutions can be obtained analytically. Only the ergodic hypothesis for the neutron population evolution is dealt with. (author)

    The proliferation of mobile devices and the emergence of wireless location-based services have generated consumer demand for precise location. In this paper, the MUSIC super-resolution algorithm is applied to time delay estimation for positioning purposes in cellular networks. The goal is to position a Mobile Station with UMTS technology. The problem of Base-Stations herability is solved using Cumulative Virtual Blanking. A simple simulator is presented using DS-SS signal. The results show that MUSIC algorithm improves the time delay estimation in both the cases whether or not Cumulative Virtual Blanking was carried out.

  8. Nutrition in adolescent pregnancy.

    Lenders, C M; McElrath, T F; Scholl, T O

    2000-06-01

    Prevention of unintended adolescent pregnancy is a primary goal of the American Academy of Pediatrics and of many health providers. Nevertheless, many adolescents become pregnant every year in America. Pediatricians therefore should be aware of nutritional recommendations for pregnant adolescents to provide optimal care. The importance of nutrition during pregnancy is here reviewed from a pediatric perspective. Pregnancy, particularly during adolescence, is a time of extreme nutritional risk. The adolescents most likely to become pregnant are often those with inadequate nutritional status and unfavorable socio-economic background. There is increasing evidence of competition for nutrients between the growing pregnant adolescent and her fetus. Also, the prenatal environment has been implicated in the development of obesity, cardiovascular disease, and diabetes in both the mother and her offspring. Many adolescents have poor diet quality and poor knowledge of appropriate nutrition; these habits may not change during pregnancy. Current knowledge and recommendations regarding the intake of energy, calcium, and folate are discussed in detail.

  9. Thrombocytopenia in Pregnancy

    2016-09-01

    Full Text Available Thrombocytopenia, which is encountered in 7-10% of pregnancies is characterized with decreased number of thrombocytes. The most frequent cause of thrombocytopenia during pregnancy is gestational thrombocytopenia. These patients usually do not have symptoms due to mild thrombocytopenia. The diagnosis is usually established by excluding connective tissue disorders, drug effects and obstetric causes. The etiology of thrombocytopenia during early pregnancy is most frequently due to autoimmune causes. Thrombocytopenia secondary to obstetric causes like preeclampsia, HELLP syndrome should always be kept in mind. Under these circumstances the thrombocytopenia will not resolve unless pregnancy is terminated. The clinician should be able to distinguish between thrombocytopenia that does not require treatment and the causes that require emergent and serious medical interventions.

  14. Radiation risks in pregnancy

    International Nuclear Information System (INIS)

    Mossman, K.L.; Hill, L.T.

    1982-01-01

    A major contraindication of radiodiagnostic procedures is pregnancy. Approximately 1% of all pregnant women are given abdominal x-rays during the first trimester of pregnancy. Evaluation of radiation exposure should involve consideration of the types of examinations performed and when performed, as well as radiation dose and risk estimation. This information is then weighed against other possible risks of the pregnancy as well as personal factors. In the authors' experiences, radiation exposures usually result in doses to the embryo of less than 5 cGy (rad); the resulting radiation risks are usually small compared with other risks of pregnancy. Procedures to minimize diagnostic x-ray exposure of the fetus are also discussed

  18. Binge drinking in pregnancy

    DEFF Research Database (Denmark)

    Kesmodel, Ulrik Schiøler

    2001-01-01

    Independent of average alcohol intake, the effect of binge drinking on adverse pregnancy outcomes in humans is only sporadically reported, but most studies in humans have found little or no effect of binge drinking on several adverse pregnancy outcomes. In a representative sample of 371 pregnant...... Danish women, the agreement between two different measures of binge drinking during the first half of pregnancy obtained from interviews and questionnaires was assessed, and the frequency and pattern of binge drinking were described. The percentage of agreement between the methods ranged between 81......% and 86%. The proportion of women who reported binge drinking depended on the definition of pregnancy, but the proportion peaked in week 3 measured from the last menstrual period and thereafter declined to approximately 1 percent in week 7. On the basis of this 1998 study, it is suggested that most human...

  7. Endoscopy in pregnancy.

    LENUS (Irish Health Repository)

    O'mahony, Seamus

    2012-02-03

    Endoscopy is rarely required during pregnancy. The potential risks of endoscopy during pregnancy include foetal hypoxia due to sedative drugs and exposure to radiation. There is no evidence that endoscopy precipitates premature labour, and studies in this area have concluded that endoscopy during pregnancy is generally safe. There should be a strong indication for the procedure, which should be deferred whenever possible to the second trimester. Procedures should be performed without any sedation, or with the lowest dose of sedative medication. Radiation exposure should be kept to a minimum. Support should be obtained from specialists in obstetrics and anaesthesia. Indications for endoscopy during pregnancy are as follows: (1) gastroscopy: upper gastrointestinal bleeding, dysphagia, uncontrolled nausea\\/vomiting; (2) sigmoidoscopy\\/colonoscopy: rectal bleeding, diarrhoea; and (3) ERCP: choledocholithiasis, biliary pancreatitis. Sedative drugs, such as midazolam appear to be safe if used carefully. Radiation exposure during ERCP can be kept well below the danger level for teratogenicity.

  10. Transient osteoporosis of pregnancy.

    Science.gov (United States)

    Maliha, George; Morgan, Jordan; Vrahas, Mark

    2012-08-01

    Transient osteoporosis of pregnancy (TOP) is a rare yet perhaps under-reported condition that has affected otherwise healthy pregnancies throughout the world. The condition presents suddenly in the third trimester of a usually uneventful pregnancy and progressively immobilizes the mother. Radiographic studies detect drastic loss of bone mass, elevated rates of turnover in the bone, and oedema in the affected portion. Weakness of the bone can lead to fractures during delivery and other complications for the mother. Then, within weeks of labour, symptoms and radiological findings resolve. Aetiology is currently unknown, although neural, vascular, haematological, endocrine, nutrient-deficiency, and other etiologies have been proposed. Several treatments have also been explored, including simple bed rest, steroids, bisphosphonates, calcitonin, induced termination of pregnancy, and surgical intervention. The orthopedist plays an essential role in monitoring the condition (and potential complications) as well as ensuring satisfactory outcomes for both the mother and newborn.

    International Nuclear Information System (INIS)

    Trott, K.H.; Gesellschaft fuer Strahlen- und Umweltforschung m.b.H., Neuherberg

    1978-01-01

    In confirmed or presumptive pregnancy it is especially critical to determine the indications for X-ray examination. This assumes that every young woman, before an examination in the pelvic region, be asked explicity when her last normal period was. Examinations of the pelvis which are not acutely necessary should be postponed until the first 10 days after menstruation. If radiologic examination of the true pelvis must be carried out despite pregnancy or is inadvertently done because pregnancy was not recognized, the radiation exposure of the embryo is so small in most cases because of modern dose-sparing equipment, that an interruption of pregnancy is not justified. A dose of less than 1 rad is, as a rule, justifiable, but it is less justifiable that alarmed, uninformed physicians instill a deep-seated fear of giving brith to a freak in a woman through false information.

  15. [Chronic hypertension and pregnancy].

    Science.gov (United States)

    Lecarpentier, Edouard; Tsatsaris, Vassili

    2012-09-01

    Hypertensive disorders in pregnancy are a leading cause of maternal and perinatal mortality and morbidity. The management of patients with chronic hypertension requires a multidisciplinary approach prior to conception, during pregnancy and post-partum. In the preconception period, fetotoxic agents should be discontinued. It is also essential to undertake a full cardiovascular examination which may, in some cases, question the possibility of pregnancy. During pregnancy, blood pressure should be monitored and controlled, but not necessarily returned to a normal value. Low blood pressure levels could indeed lead to placental hypoperfusion and fetal growth restriction. Close clinical, biological and ultrasound monitoring is recommended, even postpartum, since those patients are at higher risk for preeclampsia.

    Gargallo Fernández, Manuel

    2013-11-01

    Association of hyperthyroidism and pregnancy is not an unusual event, and has an impact on both the mother and fetus. After delivery, it may also affect the newborn and the nursing mother. Clinical management of this situation is quite different from that required by non-pregnant hyperthyroid women and poses significant diagnostic and therapeutic challenges. This review addresses aspects related to the unique characteristics of biochemical assessment of thyroid function in pregnancy, the potential causes of hyperthyroidism in pregnancy, and the clinical and therapeutic approach in each case. Special attention is paid to pregnancy complicated with Graves' disease and its different the maternal, fetal, neonatal, and postnatal consequences. Copyright © 2012 SEEN.

  12. Pregnancy and rheumatic diseases.

    Science.gov (United States)

    Gayed, M; Gordon, C

    2007-11-01

    Pregnancy is an issue that should be discussed with all patients with rheumatic diseases who are in the reproductive age group. Infertility is rarely due to the disease but can be associated with cyclophosphamide therapy. Most rheumatic diseases that are well controlled prior to pregnancy do not deteriorate in pregnancy, providing that the patient continues with appropriate disease-modifying therapy. Some patients with inflammatory arthritis go in to remission during pregnancy. Patients with renal involvement may be at increased risk of disease flare. This needs to be distinguished from pre-eclampsia. Intrauterine growth restriction is more likely in patients with active systemic disease, hypertension, a history of thrombosis and renal involvement. Premature delivery may need to be planned to reduce the risks of stillbirth and can be associated with a variety of neonatal complications. Post-partum flare is common in all the rheumatic diseases.

    2017-04-01

    Full Text Available Purpose: To elucidate drug use before and during pregnancy in Japan. Methods: The Japan Environment and Children’s Study (JECS is an ongoing nationwide birth cohort study. We analyzed data from JECS involving cases where drugs were used for 12 months before pregnancy was diagnosed, between the time of diagnosis of pregnancy until week 12 of pregnancy, and after week 12 of pregnancy. Results: We analyzed data from 97,464 pregnant women. The percentages of pregnant women who had taken one or more drugs and supplements before diagnosis of pregnancy, between the time of diagnosis of pregnancy until week 12 of pregnancy, and after week 12 of pregnancy, were 78.4%, 57.1%, and 68.8% respectively. Excluding iron supplements, folic acid, and other vitamins and minerals, the percentages of women taking supplements were 75.3%, 36.0%, and 51.7% at each respective time point. The following drugs and supplements were frequently used for 12 months before pregnancy diagnosis: Commercially available antipyretics, analgesics, and/or medicine for treating common cold (34.7%, antipyretics, analgesics, and/or medicine for treating common colds, which were prescribed in hospitals (29.8%, antimicrobial drugs (14.0%, and anti-allergy drugs (12.5%. The following drugs and supplements were frequently used from the time of pregnancy diagnosis until week 12 of pregnancy, and after week 12 of pregnancy: folic acid (28.9% and 26.2%, antipyretics, analgesics and/or medicines for treating common cold, that were prescribed in hospitals (7.8% and 13.3%, Chinese herbal medicines (6.0% and 9.4%, and uterine relaxants (5.1% and 15.2%. Conclusions: The analysis of a nationwide cohort study showed that a high percentage of Japanese pregnant women were taking medicinal drugs. Further research is required to elucidate the relationship between drug use during pregnancy and birth defects in Japan.

    The aim of this study was to determine the effects of the cumulative gain in expertise in carrying out handmade cloning (HMC) procedures on embryo yield and pregnancy outcome in cattle. Results from in vitro and in vivo embryo development after HMC during three periods of 7 months, separated by 3-month intervals, were compiled and designated as P1, P2 and P3. Blastocyst yield, morphological quality and stage of development, and pregnancy per embryo transfer (ET) on Day 30 of gestation were compared. Zona-intact oocytes were activated chemically in each experiment replicate, and development of parthenogenetic blastocysts was used as a control measurement of oocyte quality and in vitro culture conditions. A total of 21,231 cumulus-oocyte complexes (COCs) were in vitro-matured, with 5,432, 10,721 and 5078 COCs used in 16, 18 and 10 replicates for P1, P2 and P3, respectively. Cloned blastocyst yields on Day 7 increased from 15.5% (124/798) in P1 to 21.6% (309/1428) and 36.6% (280/764) in P2 and P3, respectively. No differences were observed in blastocyst development of parthenogenetic embryos, which average 30.0, 37.6, and 36.4% in P1, P2, and P3, respectively. A 10-fold higher probability of obtaining cloned blastocysts at more advanced stages of development and of higher morphological grade was seen during P3 compared with P1. Pregnancy per ET on Day 30 also increased with gain in expertise, being 6.7% (2/30), 20.8% (10/48) and 40.0% (24/60) for P1, P2 and P3, respectively. The relative efficiency for the establishment of pregnancies (per total COC) increased from 0.04% (1:2716) in P1 to 0.22% (1:460) in P2, reaching 0.47% (1:212) in P3. Results demonstrated a gradual improvement in in vitro and in vivo embryo development over time after establishment of HMC procedures in the laboratory, highlighting the importance of gaining experience and technical skills on the overall cloning efficiency.

    Pregnancy is usually associated with significant regression in genito-genital intercourse frequency, sexual desire and satisfaction. The aim of the study was to determine women's sexual habits during the third trimester of gestation and to compare their sexual activity before the current pregnancy and during previous pregnancies in case of multiparas. The study material consisted of women in the third trimester of pregnancy, recruited from the Outpatient Clinic of the 1st Department of Obstetrics and Gynecology, Medical University of Warsaw between January 2013 and February 2014, who filled out a self-prepared questionnaire. The questionnaire consisted of three parts: demographic data, sexual activity prior to current pregnancy and during gestation, including sexual positions and sources of knowledge regarding the subject. The survey involved 25 questions and was distributed among 220 patients, out of which 165 were returned and 149 properly filled out and analyzed. The average age of the respondents was 29.6 ± 4.85 years; the majority (78.8%) were in an uncomplicated pregnancy. The decrease in sexual activity was evident in all age groups--the majority usually had sex 1 to 3 times a month in contrast to 1-2 times a week prior to conceiving. Sexual activity decreased significantly with increasing age. The main reasons for abandoning sexual activity included: decreased libido (35.5%), the doctor's suggestion (29%) and fears concerning child's health (29%). During pregnancy the frequency of vaginal intercourse significantly decreased (100% prior to vs. 86.6% during pregnancy; p < 0.001); as did oral sex (44.3% vs. 29.5%; p = 0.043) and anal sex (12% vs. 5.4%; p = 0.02). 54% of the respondents declared reduced satisfaction with sexual life during pregnancy in comparison with the previous period; almost half (43.5%) felt less attractive while pregnant. The same claim was related to libido--it decreased in 58.8% of respondents. Multiparas tended to have sexual

    Alcohol consumption during pregnancy is a major cause of mental retardation in Western countries. Fetal alcohol syndrome (FAS) is mainly characterized by pre- and postnatal stunted growth, neurocognitive disorders, and facial dysmorphism. It compromises the intellectual and behavioral prognosis of the child. Prevention tools exist, through better information of health professionals, for optimal care of high-risk women before, during, and after pregnancy, which would decrease the incidence of SAF in the future.

    Objective: This study was carried out to determine the frequency, etiological factors, modes of presentation, accuracy of diagnostic modalities, operative findings and surgical treatment of tubal pregnancies. Design: Observational study. Place and duration of study: This study was conducted in gynae unit iii, Sir Ganga Ram Hospital, Lahore from January 1995 to December 1996. Subject and Methods: All the patients diagnosed as a case of tubal pregnancy in two years period were included in the study. Detailed history regarding the symptoms and risk factors of tubal pregnancy was taken followed by clinical examination. The diagnostic and treatment modality used and operative findings were also recorded. All the data was recorded on a proforma and finally the results were analysed. Results: Incidence of tubal pregnancy was found out to be 1:305 deliveries. Out of these, 70% of the cases occurred in the age group of 21-30 years and in patients with low parity (in para 0-2) 65% of the patients had high risk factor e.g previous abdominopelvic surgery PID or history of infertility. Pain was the commonest symptom (90% of cases) followed by vaginal bleeding (80%) adnexal masses (70%) and amenorrhea (65%). Acute tubal pregnancy was found in 85% of the cases while 15% of cases had chronic tubal pregnancy. Tubal pregnancy in the ampullary region was detected in 65% patients. Conclusion: Previous abdominopelvic surgery, PID or history of infertility and use of intra-uterine contraceptive device are the main etiologic factors. Most of the patients present at a very late stage with ruptured tubal pregnancy followed by salpingostomy in 95% of cases. Only 5% of cases had conservative surgical treatment i.e salpingostomy. Culdocentesis ultrasonography and laparoscopy were good diagnostic modalities. (author)

  7. Pregnancy-associated severe sepsis.

    2016-04-01

    This article examines the contemporary knowledge and uncertainties about the burden of pregnancy-associated severe sepsis (PASS), and its manifestations, management, and outcomes. There are relatively sparse data on PASS, related in part to infrequent reports and varying use of terminology and case definitions. PASS remains rare, although its incidence appears to be rapidly rising in some high-resource countries, affecting especially women with limited resources, minorities, and those with chronic illness. High level of clinician vigilance and rapid initiation of appropriate antimicrobial therapy, coupled with effective systemic support for organ dysfunction and correction of occult and overt hypoperfusion are the keys to limit adverse outcomes. However, timely diagnosis and provision of effective care remain a challenge, with reported prevalent delay in recognition and delivery of time-sensitive care interventions among maternal decedents. The mortality rate of PASS has been rising and its case fatality, although relatively low, has remained unchanged, in contrast to the outcome gains in the general population. The long-term sequelae of PASS remain unknown. The relatively limited contemporary data on PASS suggest a rising public health hazard in the obstetric population in high-resource countries, with ongoing challenges in assuring consistent provision of time-sensitive care.

    Full Text Available Background. The hormonal milieu associated with pregnancy has become a focus of interest owing to potential links with the developmental origins of health and disease. Phytoestrogens are hormonally active plant-derived chemicals that may have an impact on human reproductive processes. However, developmental exposure to phytoestrogens has not been well characterized and thus our objective was to quantify phytoestrogen exposure during pregnancy and lactation. Methods. Women in the second trimester of pregnancy entered the study during counseling for prenatal genetic information. Women who had an indication for a genetic amniocentesis on the basis of late maternal age were approached for inclusion. They completed an environmental questionnaire; a sample of amniotic fluid was collected for karyotype, blood was collected from women during pregnancy and at birth, from the umbilical cord and breast milk. Samples were tested for the presence of daidzein and genistein by GC Mass Spectroscopy. Findings. Phytoestrogens are commonly found in pregnant women’s serum and amniotic fluid during pregnancy. There is a sex difference in the concentrations with higher levels in amniotic fluid containing female fetuses. This difference was not present in maternal serum. Soy ingestion increases amniotic fluid phytoestrogen concentrations in female and male fetuses. The presence and concentrations of phytoestrogens did not differ in relation to common pregnancy complications or preexisting infertility.

    Even though pregnancy is rare with cirrhosis and advanced liver disease, but it may co-exist in the setting of non-cirrhotic portal hypertension as liver function is preserved but whenever encountered together is a complex clinical dilemma. Pregnancy in a patient with portal hypertension presents a special challenge to the obstetrician as so-called physiological hemodynamic changes associated with pregnancy, needed for meeting demands of the growing fetus, worsen the portal hypertension thereby putting mother at risk of potentially life-threatening complications like variceal hemorrhage. Risks of variceal bleed and hepatic decompensation increase many fold during pregnancy. Optimal management revolves round managing the portal hypertension and its complications. Thus management of such cases requires multi-speciality approach involving obstetricians experienced in dealing with high risk cases, hepatologists, anesthetists and neonatologists. With advancement in medical field, pregnancy is not contra-indicated in these women, as was previously believed. This article focuses on the different aspects of pregnancy with portal hypertension with special emphasis on specific cause wise treatment options to decrease the variceal bleed and hepatic decompensation. Based on extensive review of literature, management from pre-conceptional period to postpartum is outlined in order to have optimal maternal and perinatal outcomes. PMID:25755552

  10. Iron homeostasis during pregnancy.

    Fisher, Allison L; Nemeth, Elizabeta

    2017-12-01

    During pregnancy, iron needs to increase substantially to support fetoplacental development and maternal adaptation to pregnancy. To meet these iron requirements, both dietary iron absorption and the mobilization of iron from stores increase, a mechanism that is in large part dependent on the iron-regulatory hormone hepcidin. In healthy human pregnancies, maternal hepcidin concentrations are suppressed in the second and third trimesters, thereby facilitating an increased supply of iron into the circulation. The mechanism of maternal hepcidin suppression in pregnancy is unknown, but hepcidin regulation by the known stimuli (i.e., iron, erythropoietic activity, and inflammation) appears to be preserved during pregnancy. Inappropriately increased maternal hepcidin during pregnancy can compromise the iron availability for placental transfer and impair the efficacy of iron supplementation. The role of fetal hepcidin in the regulation of placental iron transfer still remains to be characterized. This review summarizes the current understanding and addresses the gaps in knowledge about gestational changes in hematologic and iron variables and regulatory aspects of maternal, fetal, and placental iron homeostasis. © 2017 American Society for Nutrition.

  11. Thrombophilia and Pregnancy Complications

    Directory of Open Access Journals (Sweden)

    Louise E. Simcox

    2015-11-01

    Full Text Available There is a paucity of strong evidence associated with adverse pregnancy outcomes and thrombophilia in pregnancy. These problems include both early (recurrent miscarriage and late placental vascular-mediated problems (fetal loss, pre-eclampsia, placental abruption and intra-uterine growth restriction. Due to poor quality case-control and cohort study designs, there is often an increase in the relative risk of these complications associated with thrombophilia, particularly recurrent early pregnancy loss, late fetal loss and pre-eclampsia, but the absolute risk remains very small. It appears that low-molecular weight heparin has other benefits on the placental vascular system besides its anticoagulant properties. Its use is in the context of antiphospholipid syndrome and recurrent pregnancy loss and also in women with implantation failure to improve live birth rates. There is currently no role for low-molecular weight heparin to prevent late placental-mediated complications in patients with inherited thrombophilia and this may be due to small patient numbers in the studies involved in summarising the evidence. There is potential for low-molecular weight heparin to improve pregnancy outcomes in women with prior severe vascular complications of pregnancy such as early-onset intra-uterine growth restriction and pre-eclampsia but further high quality randomised controlled trials are required to answer this question.

    Changes in the moles of pregnant women are frequently attributed to pregnancy, but recent studies suggest that pregnancy does not induce significant physiologic changes in nevi. It is common for nevi on the breasts and abdomen to grow with normal skin expansion, but studies that have examined melanocytic nevi on the backs or lower extremities have found no significant changes in size during pregnancy. Several studies have also investigated the belief that moles darken during pregnancy and have found insufficient evidence to support this idea. Dermoscopically, transient changes have been identified, but none are suggestive of melanoma. Results vary in terms of histologic changes seen in samples taken from pregnant women, but all authors agree that any histopathologic features consistent with melanoma should be viewed as melanoma and not attributed to pregnancy. Biopsy specimens should be obtained promptly from any changing mole that would raise concern for malignancy in a nonpregnant patient. Such procedures can be performed safely during pregnancy.

  13. Hypertension in pregnancy

    Directory of Open Access Journals (Sweden)

    Andrea Ungar

    2007-03-01

    Full Text Available Hypertension is the most common medical problem encountered during pregnancy, complicating 2-3% of pregnancies. Hypertensive disorders during pregnancy are classified into 4 categories: chronic hypertension, pre-eclampsia/eclampsia, pre-eclampsia superimposed on chronic hypertension, and gestational hypertension. A relative paucity of investigative data, as well as the frequent difficulty in making an etiological diagnosis, may lead to problems in its management. This case report analyses current concepts regarding the hypertensive disorders of gestation, focusing on chronic hypertension. Chronic hypertension is defined as blood pressure exceeding 140/90 mmHg before pregnancy or before 20 weeks gestation. Hypertensive disorders in pregnancy may cause maternal and fetal morbidity and remain a leading source of maternal mortality. A prompt diagnosis is needed also because hypertension may be an indicator of pre-eclampsia, a condition which can evolve into serious complications. Maintaining blood pressure below 140/90 mmHg is recommended, although treatment should be determined on an individual basis. Many anti-hypertensive agents appear to be safe for use during pregnancy: methildopa has been the most studied of the anti-hypertensive drugs and has the best safety record. Labetalol, idralazine and nifedipine also have been found to be safe; ACE-inhibitors are absolutely contraindicated, because they are associated with intrauterine growth retardation.

    This study compared three different methods of teaching five basic algebra rules to college students. All methods used the same procedures to teach the rules and included four 50-question review sessions interspersed among the training of the individual rules. The differences among methods involved the kinds of practice provided during the four review sessions. Participants who received cumulative practice answered 50 questions covering a mix of the rules learned prior to each review session. Participants who received a simple review answered 50 questions on one previously trained rule. Participants who received extra practice answered 50 extra questions on the rule they had just learned. Tests administered after each review included new questions for applying each rule (application items) and problems that required novel combinations of the rules (problem-solving items). On the final test, the cumulative group outscored the other groups on application and problem-solving items. In addition, the cumulative group solved the problem-solving items significantly faster than the other groups. These results suggest that cumulative practice of component skills is an effective method of training problem solving.

    Lundow, P. H.; Campbell, I. A.

    2018-02-01

    Among the Renormalization Group Theory scaling rules relating critical exponents, there are hyperscaling rules involving the dimension of the system. It is well known that in Ising models hyperscaling breaks down above the upper critical dimension. It was shown by Schwartz (1991) that the standard Josephson hyperscaling rule can also break down in Ising systems with quenched random interactions. A related Renormalization Group Theory hyperscaling rule links the critical exponents for the normalized Binder cumulant and the correlation length in the thermodynamic limit. An appropriate scaling approach for analyzing measurements from criticality to infinite temperature is first outlined. Numerical data on the scaling of the normalized correlation length and the normalized Binder cumulant are shown for the canonical Ising ferromagnet model in dimension three where hyperscaling holds, for the Ising ferromagnet in dimension five (so above the upper critical dimension) where hyperscaling breaks down, and then for Ising spin glass models in dimension three where the quenched interactions are random. For the Ising spin glasses there is a breakdown of the normalized Binder cumulant hyperscaling relation in the thermodynamic limit regime, with a return to size independent Binder cumulant values in the finite-size scaling regime around the critical region.

    Full Text Available Recent research reported evidence that contradicts cumulative prospect theory and the priority heuristic. The same body of research also violates two editing principles of original prospect theory: cancellation (the principle that people delete any attribute that is the same in both alternatives before deciding between them and combination (the principle that people combine branches leading to the same consequence by adding their probabilities. This study was designed to replicate previous results and to test whether the violations of cumulative prospect theory might be eliminated or reduced by using formats for presentation of risky gambles in which cancellation and combination could be facilitated visually. Contrary to the idea that decision behavior contradicting cumulative prospect theory and the priority heuristic would be altered by use of these formats, however, data with two new graphical formats as well as fresh replication data continued to show the patterns of evidence that violate cumulative prospect theory, the priority heuristic, and the editing principles of combination and cancellation. Systematic violations of restricted branch independence also contradicted predictions of ``stripped'' prospect theory (subjectively weighted additive utility without the editing rules.

    2018-06-01

    Multiple changes are influencing work, workplaces and workers in the US including shifts in the main types of work and the rise of the 'gig' economy. Work and workplace changes have coincided with a decline in unions and associated advocacy for improved safety and health conditions. Risk assessment has been the primary method to inform occupational and environmental health policy and management for many types of hazards. Although often focused on one hazard at a time, risk assessment frameworks and methods have advanced toward cumulative risk assessment recognizing that exposure to a single chemical or non-chemical stressor rarely occurs in isolation. We explore how applying cumulative risk approaches may change the roles of workers and employers as they pursue improved health and safety and elucidate some of the challenges and opportunities that might arise. Application of cumulative risk assessment should result in better understanding of complex exposures and health risks with the potential to inform more effective controls and improved safety and health risk management overall. Roles and responsibilities of both employers and workers are anticipated to change with potential for a greater burden of responsibility on workers to address risk factors both inside and outside the workplace that affect health at work. A range of policies, guidance and training have helped develop cumulative risk assessment for the environmental health field and similar approaches are available to foster the practice in occupational safety and health.

    During the past year the Scottish Nuclear had been working to win increased public acceptance of nuclear power in Scotland. Since then it has stepped up the PR campaign activities - and has had a very successful year. But much has still to be done. The programme 'Come and See' which was introduced in the Spring of 1991. was developed and extended introducing a Talks Service and a mobile exhibition as two new features. At the same time the Torness Power Station Visitors' Centre was opened. In 1992 a visitor's centre was opened at Hunterston Power Station. By the end of November 1992, there was almost 28,000 visitors - an increase of 48% compared to the previous year. An extensive 1.9 million pound television and newspaper advertising campaign was also mounted during the summer months. So it has been a particularly busy year and more than modestly successful. Another arm of Come and See is 'Talkabout' - the Talks Service. In 1992 members of staff gave 187 talks all over Scotland - to over 5,000 people. In the Spring of 1992 a Mobile Exhibition was also introduced. It tours the whole of Scotland. In all there have been 62 venues, a large variety of events. Over 30,000 people have visited the exhibition since March. To enhance all these Programmes a variety of literature, videos, promotional items, and static exhibition material are prepared. These have all been developed since 1990 and are kept updated on an on-going basis.

    Full Text Available Geoengineering (also called climate engineering, which refers to large-scale intervention in the Earth's climate system to counteract greenhouse gas-induced warming, has been one of the most rapidly growing areas of climate research as a potential option for tackling global warming. Here, we provide an overview of the scientific background and research progress of proposed geoengineering schemes. Geoengineering can be broadly divided into two categories: solar geoengineering (also called solar radiation management, or SRM, which aims to reflect more sunlight to space, and carbon dioxide removal (CDR, which aims to reduce the CO2 content in the atmosphere. First, we review different proposed geoengineering methods involved in the solar radiation management and carbon dioxide removal schemes. Then, we discuss the fundamental science underlying the climate response to the carbon dioxide removal and solar radiation management schemes. We focus on two basic issues: 1 climate response to the reduction in solar irradiance and 2 climate response to the reduction in atmospheric CO2. Next, we introduce an ongoing geoengineering research project in China that is supported by National Key Basic Research Program. This research project, being the first coordinated geoengineering research program in China, will systematically investigate the physical mechanisms, climate impacts, and risk and governance of a few targeted geoengineering schemes. It is expected that this research program will help us gain a deep understanding of the physical science underlying geoengineering schemes and the impacts of geoengineering on global climate, in particular, on the Asia monsoon region.

    Full Text Available Corrosion of steel reinforcement is the main cause of deterioration in reinforced concrete structures. It can result in cracking and spalling of the concrete cover. After the damaged cover is repaired, reinforcement corrosion might continue and even accelerate. While the development of the corrosion cell is difficult to control, the damage can be possibly delayed and controlled by use of a suitable repair material. The lattice fracture model is used in this paper to investigate the performance of strain hardening cementitious composite (SHCC in concrete repair systems exposed to ongoing corrosion. Numerical results were verified by experimental tests when SHCC, nonreinforced material (repair mortar, and commercial repair mortar are used as repair materials. In experiments, reinforcement bars (surrounded by a repair material were exposed to accelerated corrosion tests. The influence of the substrate surface preparation, the type of repair material, the interface, and the substrate strength on the resulting damage and failure mode of repair systems are discussed. In general, SHCC repair enables distributed cracking with small crack widths, up to several times smaller compared to repair mortar. Furthermore, more warning signs prior to the final failure are present in the SHCC repair system.

    Until recently, leprosy had been prominent in 33 countries worldwide, and Vietnam was ranked among the top 14 endemic countries. The leprosy situation in Vietnam was reviewed as a sample of the worldwide ongoing medical and social struggle to assess the need for continued support for leprosy control activities and for social programs of integration of leprosy victims into the community. A search was conducted of official Vietnamese publications, World Health Organization documents, major electronic databases, and popular leprosy Web sites; as well, notes from visits to local leprosy clinics and interviews with health workers were checked. Important achievements were realized through national determination and international collaboration. In contrast with the impressive performance statistics at the national level, and despite strong government efforts for leprosy control, the results obtained at the province-city and district-commune levels still exhibit deficiencies in case detection, treatment, and socioeconomic integration of leprosy victims. The struggle to eliminate such a complex and destructive infectious disease as leprosy does not end with the cure. Deep-seated medical and social problems remain. These problems are best solved through community-based approaches.

    Full Text Available Caroline L Knight, Catherine Nelson-Piercy Division of Women’s Health, Women’s Health Academic Centre, King’s College London and King’s Health Partners, St Thomas’ Hospital, London, UK Abstract: Systemic lupus erythematosus (SLE is a chronic, multisystem autoimmune disease predominantly affecting women, particularly those of childbearing age. SLE provides challenges in the prepregnancy, antenatal, intrapartum, and postpartum periods for these women, and for the medical, obstetric, and midwifery teams who provide their care. As with many medical conditions in pregnancy, the best maternal and fetal–neonatal outcomes are obtained with a planned pregnancy and a cohesive multidisciplinary approach. Effective prepregnancy risk assessment and counseling includes exploration of factors for poor pregnancy outcome, discussion of risks, and appropriate planning for pregnancy, with consideration of discussion of relative contraindications to pregnancy. In pregnancy, early referral for hospital-coordinated care, involvement of obstetricians and rheumatologists (and other specialists as required, an individual management plan, regular reviews, and early recognition of flares and complications are all important. Women are at risk of lupus flares, worsening renal impairment, onset of or worsening hypertension, preeclampsia, and/or venous thromboembolism, and miscarriage, intrauterine growth restriction, preterm delivery, and/or neonatal lupus syndrome (congenital heart block or neonatal lupus erythematosus. A cesarean section may be required in certain obstetric contexts (such as urgent preterm delivery for maternal and/or fetal well-being, but vaginal birth should be the aim for the majority of women. Postnatally, an ongoing individual management plan remains important, with neonatal management where necessary and rheumatology follow-up. This article explores the challenges at each stage of pregnancy, discusses the effect of SLE on pregnancy and

    Thyroid disorders may not only be the cause infertility but also increases the incidence of miscarriages and the morbidity of the pregnancies. During pregnancy the demand of thyroid hormones increases to about 30 - 50 % and the thyroid has to cope with this increase. In Germany the iodine intake has improved significantly during the last 20 years, but still is borderline low with an mean intake of about 120 microg iodide per day. Therefore it is still recommended that pregnant women are supplemented with about 100 - 150 microg of iodide during pregnancy and the time of breast-feeding, to avoid hypothyroidism of the foetus with concomitant delay of the brain development. Not only women with subclinical hypothyroidism, but only elevated TPO antibodies have a significant increase in early miscarriage and preterm delivery. An early supplementation with Levothyroxin despite euthyroidism might reduce these risks. Those women also more frequently develop postpartum thyroiditis. This risk can be reduced by a supplementation with selenium during and after pregnancy. Graves' disease is a rare disorder and only about 0,1 - 0,4 pregnancies are affected. The course of the disease is biphasic, with an exacerbation within the first trimester and an improvement thereafter, but a recurrence after delivery. Overt thyrotoxicosis has to be treated with propylthiouracil, to maintain euthyroidism during pregnancy. The TSH receptor antibodies are transferred to the foetus with the risk of thyrotoxicosis. Special care of the foetus is therefore necessary. Transient mild hyperthyroidism may occur in women with very high HCG levels during the first three months of pregnancy. This often is associated with hyperemesis gravidarum. Subclinical hypothyroidism of the mother will disturb the normal development of the foetus and therefore has to be treated even when TSH is within the upper normal level. Special care is necessary in women with elevated TPO antibodies, because these more often

    MATERNAL ASPECTS: Cardiorespiratory responses to exercise in pregnant women generally don't differ from those in nonpregnant women. Impairment of the cabability of the uteroplacental unit to maintain a sufficient oxygen and substrate supply to the fetus should be avoided by performing exercise in a submaximal range. Increase in body weight, a shift of the center of gravidity, and the ligamentous laxity in pregnancy lead to a certain joint instability and consecutively to an increased risk of injury. Therefore contact sports and sports with a high potential of injury are not suitable in pregnancy. Furthermore the beneficial effects of exercise on glucose metabolism especially in pregnant women with an impaired glusose tolerance, psychological well-being, delivery, and lactation are discussed. Exercise results in an elevation of the fetal heart rate. So far no pathological heart rate alterations could be observed. There are controversial findings concerning the influence of exercise on birth weight. Actually no retardation below the 10th percentile could be demonstrated. To prevent pregnancy complications like preterm labour or placental abruption exercises with a risk of blunt abdominal trauma are not recommended in the 2nd and 3rd trimester. Additionally the effects of exercise on embryogenesis and the possible implications of hyperthermia are presented. In general, pregnant women should practise exercise in a moderate, i. e. submaximal aerobic range. Preexisting cardiopulmonary diseases and pregnancy pathologies have to be considered as contraindications. Thus gestational age adapted exercise represents a safe and effective support for mother and fetus. Recommendations concerning exercise in pregnancy underwent significant changes during the past three decades. Today there is a lot of evidence for the beneficial effects of moderate exercise in pregnancy even in formerly inactive women. This review first presents aspects of maternal and fetal physiology with

    Antenatal care is aiming to reduce maternal land foetal mortality and morbidity. Maternal and foetal mortality can be due to different causes. Their knowledge allows identifying pregnancy (high risk pregnancy) with factors associated with an increased risk for maternal and/or foetal mortality and serious morbidity. Identification of high risk pregnancies and initiation of appropriate treatment and/or surveillance should improve maternal and/or foetal outcome. New risk factors are continuously described thanks to improvement in antenatal care and development in biology and cytopathology, increasing complexity in identifying high risk pregnancies. Level of risk can change all over the pregnancy. Ideally, it should be evaluated prior to the pregnancy and at each antenatal visit. Clinical examination is able to screen for intra-uterin growth restriction, pre-eclampsia, threatened for preterm labour; ultrasounds help in the diagnosis of foetal morphological anomalies, foetal chromosomal anomalies, placenta praevia and abnormal foetal growth; biological exams are used to screen for pre-eclampsia, gestational diabetes, trisomy 21 (for which screening method just changed), rhesus immunisation, seroconversion for toxoplasmosis or rubeola, unknown infectious disease (syphilis, hepatitis B, VIH). During pregnancy, most of the preventive strategies have to be initiated during the first trimester or even before conception. Prevention for neural-tube defects, neonatal hypocalcemia and listeriosis should be performed for all women. On the opposite, some measures are concerning only women with risk factors such as prevention for toxoplasmosis, rhesus immunization (which recently changed), tobacco complications and pre-eclampsia and intra-uterine growth factor restriction.

    The cumulative effects of increasing human use of the ocean and coastal zone have contributed to a rapid decline in ocean and coastal resources. As a result, scientists are investigating how multiple, overlapping stressors accumulate in the environment and impact ecosystems. These investigations are the foundation for the development of new tools that account for and predict cumulative effects in order to more adequately prevent or mitigate negative effects. Despite scientific advances, legal requirements, and management guidance, those who conduct assessments—including resource managers, agency staff, and consultants—continue to struggle to thoroughly evaluate cumulative effects, particularly as part of the environmental assessment process. Even though 45 years have passed since the United States National Environmental Policy Act was enacted, which set a precedent for environmental assessment around the world, defining impacts, baseline, scale, and significance are still major challenges associated with assessing cumulative effects. In addition, we know little about how practitioners tackle these challenges or how assessment aligns with current scientific recommendations. To shed more light on these challenges and gaps, we undertook a comparative study on how cumulative effects assessment (CEA) is conducted by practitioners operating under some of the most well-developed environmental laws around the globe: California, USA; British Columbia, Canada; Queensland, Australia; and New Zealand. We found that practitioners used a broad and varied definition of impact for CEA, which led to differences in how baseline, scale, and significance were determined. We also found that practice and science are not closely aligned and, as such, we highlight opportunities for managers, policy makers, practitioners, and scientists to improve environmental assessment.

    Initial observational studies and a systematic review published 5 years ago have suggested that obstetric and perinatal outcomes are better in offspring conceived following frozen rather than fresh embryo transfers, with reduced risks of preterm birth, small for gestational age, low birth weight and pre-eclampsia. More recent primary studies are beginning to challenge some of these findings. We therefore conducted an updated systematic review and cumulative meta-analysis to examine if these results have remained consistent over time. The aim of this study was to perform a systematic review and cumulative meta-analysis (trend with time) of obstetric and perinatal complications in singleton pregnancies following the transfer of frozen thawed and fresh embryos generated through in-vitro fertilisation. Data Sources from Medline, EMBASE, Cochrane Central Register of Clinical Trials DARE and CINAHL (1984-2016) were searched using appropriate key words. Observational and randomised studies comparing obstetric and perinatal outcomes in singleton pregnancies conceived through IVF using either fresh or frozen thawed embryos. Two independent reviewers extracted data in 2 × 2 tables and assessed the methodological quality of the relevant studies using CASP scoring. Both aggregated as well as cumulative meta-analysis was done using STATA. Twenty-six studies met the inclusion criteria. Singleton babies conceived from frozen thawed embryos were at lower relative risk (RR) of preterm delivery (0.90; 95% CI 0.84-0.97) low birth weight (0.72; 95% CI 0.67-0.77) and small for gestational age (0.61; 95% CI 0.56-0.67) compared to those conceived from fresh embryo transfers, but faced an increased risk (RR) of hypertensive disorders of pregnancy (1.29; 95% CI 1.07-1.56) large for gestational age (1.54; 95% CI 1.48-1.61) and high birth weight (1.85; 95% CI 1.46-2.33). There was no difference in the risk of congenital anomalies and perinatal mortality between the two groups. The direction

    An RCT among newly diagnosed, therapy naive women with polycystic ovary syndrome (PCOS) showed no significant differences in ovulation rate, ongoing pregnancy rate or spontaneous abortion rate in favour of clomifene citrate plus metformin compared with clomifene citrate. We wanted to assess whether there are specific subgroups of women with PCOS in whom clomifene citrate plus metformin leads to higher pregnancy rates. Subgroup analysis based on clinical and biochemical parameters of 111 women randomized to clomifene citrate plus metformin compared with 114 women randomized to clomifene citrate plus placebo. The data for age, BMI, waist-hip ratio (WHR) and plasma testosterone were available in all women, 2 h glucose in 80% of women and homeostatic model assessment for assessing insulin sensitivity (HOMA) in 50% of women. Of the women who were allocated to the metformin group, 44 women (40%) reached an ongoing pregnancy. In the placebo group, 52 women (46%) reached an ongoing pregnancy. There was a significantly different chance of an ongoing pregnancy for metformin versus placebo between subgroups based on age and WHR (P = 0.014). There was a positive effect of metformin versus placebo on pregnancy rate in older women (>or=28 years) with a high WHR, a negative effect of metformin versus placebo in young women (Metformin may be an effective addition to clomifene citrate in infertile women with PCOS, especially in older and viscerally obese patients.

    Pregnant women living in or traveling to areas with local mosquito-borne Zika virus transmission are at risk for Zika virus infection, which can lead to severe fetal and infant brain abnormalities and microcephaly (1). In February 2016, CDC recommended 1) routine testing for Zika virus infection of asymptomatic pregnant women living in areas with ongoing local Zika virus transmission at the first prenatal care visit, 2) retesting during the second trimester for women who initially test negative, and 3) testing of pregnant women with signs or symptoms consistent with Zika virus disease (e.g., fever, rash, arthralgia, or conjunctivitis) at any time during pregnancy (2). To collect information about pregnant women with laboratory evidence of recent possible Zika virus infection* and outcomes in their fetuses and infants, CDC established pregnancy and infant registries (3). During January 1, 2016-April 25, 2017, U.S. territories † with local transmission of Zika virus reported 2,549 completed pregnancies § (live births and pregnancy losses at any gestational age) with laboratory evidence of recent possible Zika virus infection; 5% of fetuses or infants resulting from these pregnancies had birth defects potentially associated with Zika virus infection ¶ (4,5). Among completed pregnancies with positive nucleic acid tests confirming Zika infection identified in the first, second, and third trimesters, the percentage of fetuses or infants with possible Zika-associated birth defects was 8%, 5%, and 4%, respectively. Among liveborn infants, 59% had Zika laboratory testing results reported to the pregnancy and infant registries. Identification and follow-up of infants born to women with laboratory evidence of recent possible Zika virus infection during pregnancy permits timely and appropriate clinical intervention services (6).

    Vaccinations protect woman and her fetus against different infectious diseases, but their application on pregnant should be extremely responsible. In this review I present information about some infectious diseases and vaccines during pregnancy. Women, planning to get pregnant should be advised to do serological tests in order to find out their immune status against some infections, leading to fetal congenital malformations (rubella, chicken pox, hepatitis B) and if necessary to get vaccinated at least a month before pregnancy. Despite the lack of vaccines against Cytomegalovirus (CMV), parvovirus 19 and Toxoplasma gondii it is good to know woman's immune status against these infections in order to clarify the clinical approach in case of future contact with sick or carriers. Parvovirus 19 could cause fetal death, while CMV could be transmitted to the child. Immune women wouldn't get sick and wouldn't transmit Toxoplasmagondii to the fetus during pregnancy. Recommended vaccines before pregnancy include vaccines against flu, human papilloma virus, MMR (morbilli, measles, rubella), Tdap (tetanus, diphtheria, whooping cough), chicken pox. CDC-Atlanta recommends during pregnancy two vaccines--against flu, in case it wasn't done before pregnancy, and Tdap during every pregnancy between 27-th and 36-th gestation week. Whooping cough is very dangerous for the baby during the first two months after birth, while it is not yet vaccinated. From this point of view it is of best interest of the mother to have strong immunity in order to transfer antibodies during breastfeeding, as well as for the father and the rest who will take care for the newborn child to be vaccinated against whooping cough. During pregnancy vaccinations against tuberculosis, morbilli, measles, rubella, meningococcal disease, typhoid fever and chicken pox are contraindicated. In case of contact vaccinations against rabies, anthrax, small pox, poliomyelitis and yellow fever should be taken into

    2014-01-01

    Pregnancy causes dramatic physiological changes in the expectant mother. The placenta, mostly foetal in origin, invades maternal uterine tissue early in pregnancy and unleashes a barrage of hormones and other factors. This foetal ‘invasion’ profoundly reprogrammes maternal physiology, affecting nearly every organ, including the heart and its metabolism. We briefly review here maternal systemic metabolic changes during pregnancy and cardiac metabolism in general. We then discuss changes in cardiac haemodynamic during pregnancy and review what is known about maternal cardiac metabolism during pregnancy. Lastly, we discuss cardiac diseases during pregnancy, including peripartum cardiomyopathy, and the potential contribution of aberrant cardiac metabolism to disease aetiology. PMID:24448314

    Sleep disordered breathing (SDB is very common during pregnancy, and is most likely explained by hormonal, physiological and physical changes. Maternal obesity, one of the major risk factors for SDB, together with physiological changes in pregnancy may predispose women to develop SDB. SDB has been associated with poor maternal and fetal outcomes. Thus, early identification, diagnosis and treatment of SDB are important in pregnancy. This article reviews the pregnancy-related changes affecting the severity of SDB, the epidemiology and the risk factors of SDB in pregnancy, the association of SDB with adverse pregnancy outcomes, and screening and management options specific for this population.

    Although the case fatality rate for ectopic pregnancies has decreased to 0.08% in industrialized countries, it still represents 3.8% of maternal mortality in the United States alone. In developing countries, the case fatality rate varies from 3% to 27%. Laparoscopic management of tubal pregnancies is now the standard form of treatment where this technology is available. Abdominal pregnancies are rare, and secondary implantation of tubal ectopic pregnancies is the most common cause of abdominal gestations. We present an interesting case of secondary implantation of a tubal ectopic pregnancy to highlight the appendix as a possible secondary implantation site after a tubal ectopic pregnancy.

Results are obtained using the standard cumulant method, as well as the two-subevent and three-subevent cumulant methods. Results from the standard method are found to be strongly biased by non-flow correlations as indicated by strong sensitivity to the chosen event class definition. A systematic reduction of non-flow effects is observed when using the two-subevent method and the results become independent of event class definition when the three-subevent method is used. The measured SC(n,m) shows an anti-correlation between v2 and v3, and a positive correlation between v2 and v4. The magnitude of SC(n,m) is constant with Nch in pp collisions, but increases with Nch in p+Pb and Pb+Pb collisions. ...

Methods: Fifty-four patients with complicated pregnancy and 40 healthy pregnant subjects were included the study. Factor V Leiden (FVL mutation, protein S, protein C, anti-thrombin deficiency levels were investigated. Results: Of the 54 patients with complicated pregnancy, 29 had preeclampsia, 18 had intra uterine growth retardation, and 7 had intrauterine fetal loss. The most common defect was FVL mutation. FVL mutations in patient group and the control group were 27.2% and 10%, respectively, which were statistically significant. The protein S, protein C, and anti-thrombin deficiencies were found higher in the patient group compared to control (p>0.05 for each. Conclusion: FVL mutation was found higher in patient group compared to the control group, Protein C deficiency and anti-thrombin deficiency were related to preeclampsia but not other pregnancy complications. Clinicians should take into account the thrombophilia in complicated pregnancy, especially preeclampsia. J Clin Exp Invest 2013; 4 (4: 497-502

Thyroid abnormalities are very often subclinical in nature and not easily recognized without specific screening programs. Even mild maternal thyroid hormone deficiency may lead to neurodevelopment complications in the fetus. The main diagnostic indicator of thyroid disease is the measurement of serum thyroid-stimulating hormone and free thyroxine levels. Availability of gestation-age-specific thyroid-stimulating hormone thresholds is an important aid in the accurate diagnosis and treatment of thyroid dysfunction. Pregnancy-specific free thyroxine thresholds not presently available are also required. Large-scale intervention trials are urgently needed to assess the efficacy of preconception or early pregnancy screening for thyroid disorders. Accurate interpretation of both antepartum and postpartum levels of thyroid hormones is important in preventing pregnancy-related complication secondary to thyroid dysfunction. This article sheds light on the best ways of management of thyroid dysfunction during pregnancy in order to prevent any possible maternal or fetal complication.Keywords: TSH, HCG, TBG

    Pregnancy is associated with a number of musculoskeletal problems. It is important to educate all mothers, as well as those involved in ante- and postnatal care with advice on bras and exercises that are safe in pregnancy (in particular pelvic floor exercises). There is not much that can be done to alter the inevitable physiological and hormonal changes of pregnancy. However, by strengthening the core stabilising muscles around the pelvis and spine, and improving the breathing pattern, it is hoped that one can optimise the body for the challenges it may face. Pilates is based on the principle that a central core is developed and then movements are introduced to challenge this core stability. This philosophy is clearly applicable in pregnancy--a significant test both mentally and physically on the mother's body. By maximising the mother's core stability before and during pregnancy, it should be possible to limit any potential harm. Returning to exercise soon after the birth is important for the mother's physical and mental wellbeing--she looks after her baby's body for nine months, who cares for hers?

    Women constitute a large percentage of the workforce in industrialized countries. As a result, addressing pregnancy-related health issues in the workplace is important in order to formulate appropriate strategies to promote and protect maternal and infant health. To explore issues affecting pregnant women in the workplace. A systematic literature review was conducted using Boolean combinations of the terms 'pregnant women', 'workplace' and 'employment' for publications from January 1990 to November 2010. Studies that explicitly explored pregnancy in the workplace within the UK, USA, Canada or the European Union were included. Pregnancy discrimination was found to be prevalent and represented a large portion of claims brought against employers by women. The relationship between environmental risks and exposures at work with foetal outcomes was inconclusive. In general, standard working conditions presented little hazard to infant health; however, pregnancy could significantly impact a mother's psychosocial well-being in the workplace. Core recommendations to improve maternal and infant health outcomes and improve workplace conditions for women include: (i) shifting organizational culture to support women in pregnancy; (ii) conducting early screening of occupational risk during the preconception period and (iii) monitoring manual labour conditions, including workplace environment and job duties.

    Abdominal emergencies during pregnancy (excluding obstetrical emergencies) occur in one out of 500-700 pregnancies and may involve gastrointestinal, gynecologic, urologic, vascular and traumatic etiologies; surgery is necessary in 0.2-2% of cases. Since these emergencies are relatively rare, patients should be referred to specialized centers where surgical, obstetrical and neonatal cares are available, particularly because surgical intervention increases the risk of premature labor. Clinical presentations may be atypical and misleading because of pregnancy-associated anatomical and physiologic alterations, which often result in diagnostic uncertainty and therapeutic delay with increased risks of maternal and infant morbidity. The most common abdominal emergencies are acute appendicitis (best treated by laparoscopic appendectomy), acute calculous cholecystitis (best treated by laparoscopic cholecystectomy from the first trimester through the early part of the third trimester) and intestinal obstruction (where medical treatment is the first-line approach, just as in the non-pregnant patient). Acute pancreatitis is rare, usually resulting from trans-ampullary passage of gallstones; it usually resolves with medical treatment but an elevated risk of recurrent episodes justifies laparoscopic cholecystectomy in the 2nd trimester and endoscopic sphincterotomy in the 3rd trimester. The aim of the present work is to review pregnancy-induced anatomical and physiological modifications, to describe the main abdominal emergencies during pregnancy, their specific features and their diagnostic and therapeutic management.

    Antiphospholipid syndrome (APS) is classified as the association of thrombotic events and/or obstetric morbidity in patients persistently positive for antiphospholipid antibodies (aPL). APS is also the most frequently acquired risk factor for a treatable cause of recurrent pregnancy loss and increases the risk of conditions associated with ischemic placental dysfunction, such as stillbirth, intrauterine death, preeclampsia, premature birth, and fetal growth restriction. The use of low-dose aspirin and heparin has improved the pregnancy outcome in obstetric APS and approximately 70% of pregnant women with APS will deliver a viable live infant. However, current management does not prevent all maternal, fetal, and neonatal complications of APS and the current treatment fails in 20 to 30% of APS pregnancies, raising the need to explore other treatments to improve obstetrical outcome. Two clinical studies of retrospective design have suggested that the immunomodulator hydroxychloroquine (HCQ) may play a role in the prevention of pregnancy complications in women with aPL and APS. The randomized controlled multicenter trial of hydroxychloroquine versus placebo during pregnancy in women with antiphospholipid antibodies (HYPATIA) of HCQ versus placebo will provide scientific evidence on the use of HCQ in pregnant women with aPL.
