AbstractAimMassive post‐partum hemorrhage (PPH) is an important cause of maternal death that occurs as a complication of delivery. We report a large case series to evaluate the efficacy of uterine balloon tamponade to treat PPH avoiding hysterectomy.Material and MethodsThis prospective study was conducted in two Italian hospitals (from December 2002 to July 2012). Fifty‐two patients with PPH not responsive to uterotonics were treated by Rusch balloon. A follow‐up was conducted among the study population to assess the subsequent fertility.ResultsThe most frequent cause of PPH was atony (59.6%), followed by placenta previa (21.2%), placenta accreta (9.6%), and placenta previa and accreta (9.6%). The balloon success rate to control hemorrhage was 75%. From the sample of 52 patients, 13 patients needed additional procedures. In three failure cases, other conservative techniques were used and the overall effectiveness of them was 80.7%. The follow‐up group consisted of 31 women. Of these women, 24 women (77.4%) had no further pregnancies, but only one due to sterility. Four of seven patients with subsequent pregnancies made it to term without complications.ConclusionsThe Rusch balloon is effective in controlling non‐traumatic PPH in 75% of cases. It is simple to use, readily available and cheap. If necessary, this technique does not exclude other procedures. We suggest that this balloon should be included routinely in the PPH protocol.

AbstractAimThe aim of this study was to assess the influence of glucose metabolism on the expression of glycosaminoglycans (GAGs) and proteoglycans (PGs) in pregnant women.Material and MethodsSeventy‐six women in the first trimester of pregnancy (10–13 weeks) attending the Gynecologic and Obstetric Clinic, University of Sassari, were enrolled and gave early morning urine samples. Groups I, II and III included women with serum glucose values of 65–89 mg/dL, 90–99 mg/dL and 100–125 mg/dL, respectively. Urine GAGs/PGs distribution was determined by electrophoresis on cellulose acetate strips. Urinary N‐Acetyl‐β‐glucosaminidase was estimated kinetically.ResultsAnalysis of urinary GAGs/PGs electrophoretic profiles showed a significant increase in heparan sulfate (HS) excretion (P = 0.017) as well as a reduced chondroitin sulfate (CS) excretion (P = 0.048) in the group II pregnant women compared with the group I, and higher values of the HS/CS ratio in groups II and III compared to group I. Furthermore, we observed a positive correlation among fasting blood glucose levels and the relative content of HS, the HS/CS and urinary trypsin inhibitor/CS ratios, and the N‐Acetyl‐β‐glucosaminidase levels.ConclusionsThe assessment of risk factors for gestational diabetes mellitus should also take into account fasting blood glucose values of 90–99 mg/dL, as the findings of our study indicated an alteration in the metabolism of GAGs during the early stages of pregnancy.
Domestic violence is a leading risk factor in default from colposcopy services
Authors: Collier Rachael , Quinlivan Julie A. 
Published: June 2014

AbstractAimDomestic violence is common in women and is associated with poorer health‐care outcomes. However, no causal pathway has been identified to explain this observation. We have followed a cohort of women to determine whether poorer outcomes can be explained by high rates of default and loss to follow‐up.Material and MethodsA prospective cohort study was performed. Institutional ethics approval was obtained. Participants were consecutive patients attending colposcopy clinics at a major metropolitan hospital in Australia. Following ascertainment of domestic violence status, appointment outcomes for colposcopy services were tracked for a 3‐year period. Multivariate analysis was undertaken to determine demographic factors associated with default from care and loss to follow‐up.ResultsOf 581 women approached, consent was obtained from 574 women (99%). Domestic violence status was obtained from 566 women, of whom 187 (33%) had a recent history of exposure. Women exposed to violence were more likely to default from colposcopy once (26.2% vs 7.4%; P < 0.0001), twice (11.2% vs 3.2%, P = 0.0001), or thrice (10.7% vs 2.4%, P < 0.0001). They were more likely to be lost to follow‐up (8.0% vs 1.1%, P < 0.0001). In multivariate analysis, exposure to domestic violence remained significantly associated with default and loss to follow‐up.ConclusionDomestic violence is a risk factor for default from attendance and loss to follow‐up at colposcopy services. This may explain the mechanism behind adverse health‐care outcomes seen. Screening and targeted appointment intervention programs may improve clinical compliance.
Importance of optimal local uterine blood flow for implantation

Published: June 2014

AbstractAimsThe aim of this study was to determine whether uterine blood flow is an effective parameter to anticipate uterine receptivity.Material and MethodsThe local uterine blood flow was measured in the endometrium and on the outside of the uterus in mice during the early stage of pregnancy and an implantation failure mouse model using transient and local suppression of signal transducer and activator of transcription‐3 activity during implantation.ResultsThe local uterine blood flow was dramatically increased after mating and was decreased towards the time of implantation. The local uterine blood flow at 2.5 days post‐coitus in signal transducer and activator of transcription‐3 decoy transferred mice was significantly higher than in control mice. However, the range of individual values was too wide to find a cut‐off point.ConclusionsIt is necessary to decrease local uterine blood flow after ovulation to prepare the opening implantation window. The optimal local uterine blood flow is regulated by time events during pregnancy. The range of individual values of uterine blood flow is wide using a laser Doppler blood flow meter. This parameter itself may not be an appropriate parameter to evaluate the prospect of uterine receptivity.

AbstractThe ‘Clinical Guidelines for Obstetrical Practice, 2011 edition’ were revised and published as a 2014 edition (in Japanese) in April 2014 by the Japan Society of Obstetrics and Gynecology and the Japan Association of Obstetricians and Gynecologists. The aims of this publication include the determination of current standard care practices for pregnant women in Japan, the widespread use of standard care practices, the enhancement of safety in obstetrical practice, the reduction of burdens associated with medico‐legal and medico‐economical problems, and a better understanding between pregnant women and maternity‐service providers. The number of Clinical Questions and Answers items increased from 87 in the 2011 edition to 104 in the 2014 edition. The Japanese 2014 version included a Discussion, a List of References, and some Tables and Figures following the Answers to the 104 Clinical Questions; these additional sections covered common problems and questions encountered in obstetrical practice, helping Japanese readers to achieve a comprehensive understanding. Each answer with a recommendation level of A, B or C was prepared based principally on ‘evidence’ or a consensus among Japanese obstetricians in situations where ‘evidence’ was weak or lacking. Answers with a recommendation level of A or B represent current standard care practices in Japan. All 104 Clinical Questions and Answers items, with the omission of the Discussion, List of References, and Tables and Figures, are presented herein to promote a better understanding among English readers of the current standard care practices for pregnant women in Japan.

Published: June 2014

AbstractAimThe aim of this study was to evaluate the relation between abdominal scar characteristics and the severity of intra‐abdominal adhesions with repeat cesarean deliveries.MethodsA total of 208 women with at least one previous cesarean delivery at or beyond 37 weeks of gestation who were admitted for repeat cesarean delivery were enrolled in this study. Scars were categorized as depressed, flat or elevated according to their appearance, and hyperpigmented or the same color as the surrounding skin according to their pigmentation status. Intraoperative adhesions were graded according to the modified Nair's classification and categorized as no adhesion, filmy or dense adhesions.ResultsNo significant difference was found between women with or without adhesions regarding age, body mass index, gestational week at delivery, number of previous cesarean deliveries or the duration since the last cesarean delivery. Women with depressed scars had more intra‐abdominal adhesions than women with flat or elevated abdominal scars (P = 0.013). There was no significant difference in the incidence of hyperpigmented and non‐pigmented scars between women with or without adhesions (39.4% vs 41.3% and 60.6% vs 58.7%, respectively) (P > 0.05). Scar width was significantly larger in patients with intra‐abdominal adhesions than in patients without adhesions (3.6 ± 1.1 vs 3.2 ± 0.9) (P = 0.003), whereas scar length did not differ significantly (15.2 ± 1.3 vs 15.1 ± 2.1) (P > 0.005).ConclusionThere is a relation between depressed abdominal scars and intra‐abdominal adhesions, whereas pigmentation status does not differ between women with or without adhesions.
The effect of loading on peri‐implant bone: a critical review of the literature
Authors: Duyck J. , Vandamme K. 
Published: June 2014

SummaryIn the 90s, there was a general belief that mechanical overloading was one of the main reasons for late implant failure. This triggered research to assess the role of mechanical loading on the establishment and the maintenance of oral implant osseointegration. Animal experimental studies indeed suggested the potential detrimental effect of excessive mechanical load on peri‐implant bone, although randomised or controlled clinical trials of treatment interventions of oral implants designed to study overload are lacking. The lack of quantification of so‐called overload at the implant level in the intra‐oral setting is one of the main shortcomings in the literature. The level of evidence of the studies on bone response to implant loading is weak and does not indicate that overload can lead to peri‐implant bone loss, except in case of inflammation. Clinical and animal experimental studies on early and immediate implant loading, however, provide information on the impact of mechanical loading on the process of osseointegration. It is obvious that micromotion between the implant and host tissues compromises osseointegration. However, in case of an efficient force transfer between implant and surrounding tissues, mechanical loading might even stimulate peri‐implant bone formation and therefore osseointegration.

Published: June 2014

The purpose of this research is to examine the influence of firm innovativeness and product innovativeness on the components of customer value mediated by instrumental and symbolic brand benefits.Over the last 10 years, the mobile phone industry in Korea has grown rapidly, with the introduction of several innovative phone features. The research context therefore is mobile phones with Internet access and their users in Korea.A major research finding is that the firm innovativeness affects product innovativeness, and hence, the instrumental brand benefits. A firm's innovativeness also has a significant effect on the symbolic brand benefits and the partnership value.Our key academic contribution is to expand the previous fragmentary studies of customer value, by classifying customer value into four components: expectation, partnership, transaction, and relationship customer values, rather than just focusing on benefits and sacrifices.Implications for managers include the verification that firm innovativeness is a source of ability for mobile phone firms to create value for customers. Instrumental and symbolic brand benefits through innovation should be the focus area for marketers and new product development (NPD) managers in mobile phone firms to communicate with consumers to increase expectation values in the prepurchase step.
“The Great Djuna:” Two Decades of Barnes Studies, 1993–2013
Authors: Setz Cathryn 
Published: June 2014

AbstractFrom virtual oblivion, to queer feminist rebel, to significant author of the early twentieth century, Djuna Barnes has begun to be regarded an integral figure in studies of modernist literary history. Her work requires a particular attention to “high” and “low” material culture, style and form, and offers productive challenges to (among other things) genre, narratives of trauma, sexual and racial constructions of identity, exilic and transnational subjects. As students and scholars come to the author through recent critical work attuned to her modernist literary and artistic practices, it is important to take stock of this growing field. Intended as an introductory guide focused on three waves of scholarship since 1993, this article maps the key pioneering and influential critical voices, issues and directions that have illuminated Barnes studies over the past twenty years. “The great Djuna,” as one critic called her, is a moniker finally shedding its outdated irony.

Published: June 2014

AbstractObjectiveTBI causes localized cerebral ischemia that, in turn, is accompanied by both changes in BBB permeability and recruitment of CD34+ cells to the injured tissue. However, it remains unknown whether CD34+ cell recruitment is linked to BBB permeability. This study is a preliminary investigation into possible correlations between CD34+ cell recruitment and BBB permeability following TBI in a rat model.MethodsMale SD rats were subjected to mild fluid percussion injury. BBB permeability was assessed by measuring extrinsic EB dye extravasation and endogenous EBA expression at days 1, 3, 5, 7, and 12 post injury. The number of CD34+ cells in the damaged tissue was analyzed by immunohistochemistry at each time point.ResultsEB dye extravasation reached a peak at day 3 following TBI, while EBA expression displayed the reverse profile. Accumulation of CD34+ cells in injured brain tissue was evident at five days post injury. It revealed a negative linear correlation between CD34+ cell and BBB permeability.ConclusionsThe negative linear correlation between CD34+ cell recruitment and BBB permeability following TBI provides a support for further study of CD34+ cell transplantation for BBB repair after TBI.

SummaryThe extreme resistance of Saccharomyces cerevisiae to copper is overcome by 2‐(6‐benzyl‐2‐pyridyl)quinazoline (BPQ), providing a chemical‐biology tool which has been exploited in two lines of discovery. First, BPQ is shown to form a red (BPQ)2Cu(I) complex and promote Ctr1‐independent copper‐accumulation in whole cells and in mitochondria isolated from treated cells. Multiple phenotypes, including loss of aconitase activity, are consistent with copper‐BPQ mediated damage to mitochondrial iron–sulphur clusters. Thus, a biochemical basis of copper‐toxicity in S. cerevisiae is analogous to other organisms. Second, iron regulons controlled by Aft1/2, Cth2 and Yap5 that respond to mitochondrial iron–sulphur cluster status are modulated by copper‐BPQ causing iron hyper‐accumulation via upregulated iron‐import. Comparison of copper‐BPQ treated, untreated and copper‐only treated wild‐type and fra2Δ by RNA‐seq has uncovered a new candidate Aft1 target‐gene (LSO1) and paralogous non‐target (LSO2), plus nine putative Cth2 target‐transcripts. Two lines of evidence confirm that Fra2 dominates basal repression of the Aft1/2 regulons in iron‐replete cultures. Fra2‐independent control of these regulons is also observed but CTH2 itself appears to be atypically Fra2‐dependent. However, control of Cth2‐target transcripts which is independent of CTH2 transcript abundance or of Fra2, is also quantified. Use of copper‐BPQ supports a substantial contribution of metabolite repression to iron‐regulation.
Effects of case‐based learning on communication skills, problem‐solving ability, and learning motivation in nursing students

Published: June 2014

AbstractThe purpose of this study was to explore the effects of case‐based learning on communication skills, problem‐solving ability, and learning motivation in sophomore nursing students. In this prospective, quasi‐experimental study, we compared the pretest and post‐test scores of an experimental group and a nonequivalent, nonsynchronized control group. Both groups were selected using convenience sampling, and consisted of students enrolled in a health communication course in the fall semesters of 2011 (control group) and 2012 (experimental group) at a nursing college in Suwon, South Korea. The two courses covered the same material, but in 2011 the course was lecture‐based, while in 2012, lectures were replaced by case‐based learning comprising five authentic cases of patient–nurse communication. At post‐test, the case‐based learning group showed significantly greater communication skills, problem‐solving ability, and learning motivation than the lecture‐based learning group. This finding suggests that case‐based learning is an effective learning and teaching method.
Revisiting the macroeconomic effects of oil and food price shocks toPakistan economy: a structural vector autoregressive (SVAR) analysis
Authors: Khan Muhammad Arshad , Ahmed Ayaz 
Published: June 2014

AbstractThis study examines the impact of global food and oil price shocks and their transmission channels to the selected macroeconomic variables including the inflation rate, output, money balances, interest rate and real effective exchange rate forPakistan using monthly data over the period 1990M1–2011M7. An empirical analysis is carried out by employing a structural vector autoregressive framework to identify different structural shocks and explore the relative contribution of oil and food price shocks. Generalised impulse response functions and generalised forecast variance decompositions are employed to track the impact of oil and food price shocks onPakistan's economy. The results suggest that oil price shocks negatively affect industrial production, appreciates real effective exchange rate and positively affect inflation, either the shocks are positive or negative. Only the oil and food price shocks have asymmetric impact on the short‐term interest rate. In contrast, following the positive (or negative) food price shock, industrial output, interest rate and inflation rate respond positively. However, the variation in interest rate due to food price shock is relatively larger than that of oil price shocks. Generalised impulse response functions reveal that real effective exchange rate is the most important source of disturbances following either oil price or food price shocks. Generalised forecast variance decompositions analysis also supports the findings based on generalised impulse response functions. The results clearly reveal that oil and food price shocks significantly affect output, short‐term interest rate, inflation rate and the real effective exchange rate. However, among all, real effective exchange rate has been a dominant source of variation inPakistan. This implies that supply‐side and demand‐side disturbances originated by external shocks are the major sources of variation in output and inflation inPakistan.
Long‐term relationships between electricity and oil, gas and coal future prices—evidence fromNordic countries,ContinentalEurope and theUnitedKingdom

Published: June 2014

AbstractThis paper investigates the relationship between futures prices of electricity, on the one hand and crude oil, natural gas and coal on the other hand, in theUnitedKingdom,German andNordic energy markets. Energy traders and market participants use statistical models in their trading activities. We seek to establish robust cointegration based models as decision tools for energy commodity spread trading. We look at three different markets with different input mixtures, for electricity generation. Using daily futures data from period 2006 to 2012, we find cointegration betweenUKelectricity prices andCoal andGas, and betweenNordic electricity prices andCoal. The spread betweenGerman electricity prices andGas,Oil andCoal prices are also stationary. The consequence of this finding could be a possible trading strategy which involves buying electricity futures and selling gas or coal when the spread is above the mean and reversing the strategy when the spread is below the mean. The suggested strategy assumes a reversion to the mean, which we show takes some time, as displayed by the slow speed of adjustment.
Art and Aesthetic Behaviors as Possible Expressions of our Biologically Evolved Human Nature
Authors: Davies Stephen 
Published: June 2014

AbstractIn this paper, I review arguments that have been offered in favor of the view that humans' art and/or aesthetic behaviors are (in part) a product of our biologically evolved human nature, either as adaptations in their own right or as incidental byproducts of adaptations with non‐art and non‐aesthetic functions. I present an overview of the main positions and options, critically evaluate their strengths and weaknesses, and outline their presuppositions.
