Laparoscopy in urogynaecology
Authors: Khasriya Rajvinder , Vashisht Arvind , Cutner Alfred
Published: April 2018

Key content

Laparoscopic surgery has the potential to further develop urogynaecological surgery.

Laparoscopic urogynaecological surgery allows improved visualisation of pelvic organs, reduced postoperative pain, shorter admission and a quicker return to activities of daily living.

There is growing interest in new treatments for prolapse with the advent of operations enabling uterine conservation, and a revival in abdominal vaginal vault procedures and colposuspensions.

Operative laparoscopy requires a high degree of technical skill and training. It is difficult for trainees to universally gain good exposure to higher laparoscopic training.

Learning objectives

To understand the different laparoscopic urogynaecology procedures available to treat prolapse and stress incontinence, thus promoting patient choice for surgery.

To appreciate the techniques of laparoscopic hysteropexy and laparoscopic colposuspension.

To understand the importance of training in laparoscopic urogynaecology, both hands‐on and simulation‐based.

Ethical issues

Concern regarding complications of vaginally inserted meshes to treat prolapse has increased interest in laparoscopic techniques to treat prolapse.

The question is raised as to whether urogynaecology surgery should only be offered at specialist centres.
Does Foreign Exchange Volume Activity Predict Foreign Exchange Returns? Evidence from Buy-Sell Volume in the Euro-Dollar Market
Authors: Spohn David
Published: April 2018

This paper investigates the predictive ability of lagged buy-sell volume on current foreign exchange returns. Using novel Euro-Dollar foreign exchange market data from 2007 to 2015, we show that the buy-sell volume has an inverse correlation with current foreign exchange returns. Using conditional regression analysis, buy-sell volumes predict subsequent Euro-Dollar returns. We divide the data into two sub-samples. We use the first sub-sample to create a trading rule, and we use the second sub-sample to test the rule. After adjusting for time-varying calendar effects, we find that a profitable trading strategy exists using only buy-sell volume to predict returns.
The Philosophy of Sport as Artistic Expression
Authors: Shorkend Danny
Published: April 2018

While there is no “expressive theory of sport”, there is certainly, according to Hyland (1984, 1990), Osterhoudt (1973), Kerr (1997) and Weis (1969) a pivotal role played by emotions and feelings in sport which amount to a type of expressive theory and in that sense it parallels expressive theories in art. In this article I will first isolate three moments that capture sports performance and parallel art. Then, I will describe sport as an expression of emotional release, which is often how one understands art. Based on such overlaps, I will argue for two philosophical observations that devolve from such a comparison, namely ineffability and the unity of mind-body (in sport). Finally, I will apply a reading of Kant to sport, in order to substantiate the idea that sport, like art draws from a philosophical heritage.Imagine three isolated “steps” in sport: the focus before performance; the performance itself and the fan’s response as they articulate the emotional basis of sport which is familiar, albeit perhaps subconscious. After a brief analysis of these imagined images, I give a simplified historical outline of sport which describes the feeling-basis of play that forms the foundation for modern sport. I then examine what I have termed the “(surplus) expressive-energy theory of sport” which I have gleaned from the above writers, a theory that argues that sport is the expression of inner emotional states. Such states are in need of expiation of both the practitioner as well as the expression of certain basic emotions on the part of the audience. A narrower version of this theory is that sport is the release of aggressiveness, which coheres with its instinctual origins and the “surplus theory”. A critique of sport as expression (of surplus energy, aggression…) follows with a view to highlight some shortcomings in the ideas presented and thus the need for further theories to account for the multi-faceted nature of sport, a similar requirement that is needed for art given the shortcomings of expressive theories as applied to the arts.

Published: April 2018

Introduction

Safe management of warfarin in the inpatient setting can be challenging. At the Mayo Clinic hospitals in Rochester, Minnesota, we set out to improve the safety of warfarin management among surgical and non-surgical inpatients.

Methods

A multidisciplinary team designed a pharmacist-managed warfarin protocol (PMWP) which designated warfarin dosing to inpatient pharmacists with guidance from computerised dosing algorithms. Ordering this protocol was ultimately designed as an ‘opt out’ practice. The primary improvement measure was frequency of international normalised ratio (INR) greater than 5; secondary measures included adoption rate of the protocol, a counterbalance INR metric (INR <1.7 three days after first inpatient warfarin dose), and complication rates, including bleeding and thrombosis events. An interrupted time series analysis was conducted to compare outcomes.

Results

Among over 50 000 inpatient warfarin recipients, the PMWP was adopted for the majority of both surgical and non-surgical inpatients during the study period (1 January 2005 to 31 December 2011). The primary improvement measure decreased from 5.6% to 3.4% for medical patients and from 5.2% to 2.4% for surgical patients during the preimplementation and postimplementation periods, respectively. The INR counterbalance measure did not change. Postoperative bleeding decreased from 13.5% to 11.1% among surgical patients, but bleeding was unchanged among medical patients.

Conclusion

Our PMWP led to achievement of improved INR control for inpatient warfarin recipients and to less near-term bleeding among higher risk, surgical patients.
Digital technologies for the assessment of cognition: a clinical review
Authors: Chinner Amy , Blane Jasmine , Lancaster Claire , Hinds Chris , Koychev Ivan
Published: April 2018

Dementia is the most widespread form of neurodegenerative disorder and is associated with an immense societal and personal cost. Prevalence of this disorder is projected to triple worldwide by 2050 leading to an urgent need to make advances in the efficiency of both its care and therapy research. Digital technologies are a rapidly advancing field that provide a previously unavailable opportunity to alleviate challenges faced by clinicians and researchers working in this area. This clinical review aimed to summarise currently available evidence on digital technologies that can be used to monitor cognition. We identified a range of pervasive digital systems, such as smartphones, smartwatches and smart homes, to assess and assist elderly demented, prodromal and preclinical populations. Generally, the studies reported good level of agreement between the digital measures and the constructs they aimed to measure. However, most of the systems are still only in the initial stages of development with limited data on acceptability in patients. Although it is clear that the use of digital technology to monitor and support the cognitive domains affected by dementia is a promising area of development, additional research validating the efficacy, utility and cost-effectiveness of these systems in patient populations is needed.
Lateral torsional buckling of welded wide flange beams under constant moment
Authors: Kabir Imran , Bhowmick Anjan K.
Published: April 2018

The structural steel design specification in Canada, CSA S16-14, uses the same equations for the design of rolled and welded shape beams for lateral torsional buckling (LTB). A recent study has shown that the current design equations might overestimate the capacity of welded wide flange (WWF) beams. This paper evaluates the performance of the current design equations in providing LTB capacities of welded I-shape beams (WWF beams). An extensive finite element (FE) analysis is performed for simply supported WWF beams subjected to constant moment. In total, 256 FE models are analyzed and it is observed that both CSA and AISC overestimate the LTB capacity of welded I-shape beams by as much as 37%, particularly when residual stress measured at Lehigh University is used in the analysis. Also, the Eurocode is found to be conservative and the proposed equation by MacPhedran and Grondin in 2011 provides better predictions of LTB strengths of WWF shapes than the current CSA approach.
Changes in bryophytes assemblages along a chronosequence in eastern boreal forest of Quebec
Authors: Boudreault C. , Paquette M. , Fenton N.J. , Pothier D. , Bergeron Y.
Published: April 2018

Old-growth forests are often considered as biodiversity hotspots for bryophytes because of their diversity in environmental niches or microhabitats and forest continuity. Following this hypothesis, old-growth forests would be expected to house species and functional traits associated with species dispersal different from mature forests. In this study, we compared bryophytes in old-growth and younger forests in terms of species composition, functional trait values, and microhabitat associations. We studied bryophytes in 22 sites distributed across three age classes (18 to >200 years) in boreal forests (eastern Quebec). Richness of liverworts, vegetative-reproducing species, and species with infrequent sexual reproduction were higher in the oldest age class. Species richness was best explained by the availability of coarse woody material (CWM) and other microhabitats, and community structure was best explained by balsam fir basal area. Microhabitats most often associated with indicator species were organic matter, CWM, and pits. Our results indicate that communities associated with older forests are potentially sensitive to forest management as they differ in composition and functional traits from other age classes, with many species characterized by reduced dispersal capabilities and tolerance to competition. An approach that combines critical source habitat protection for dispersal-limited species with protection of critical microhabitats in neighboring managed stands are necessary to allow successful recolonization and maintain bryophyte diversity in managed landscapes.
The (new) role of public forest administration in Western Balkans: examples from Serbia, Croatia, FYR Macedonia, and Republika Srpska

Published: April 2018

Public forest administrations in the Western Balkans were challenged when facing novel forest policies following the breakup of Yugoslavia in the 1990s. To answer (i) what (formal) goals lead public forest administrations nowadays and (ii) how do public forest administrations fulfil these goals, we evaluated the implementation of forest policy goals in Serbia, Croatia, FYR Macedonia, and Republika Srpska by using existing criteria and indicators and the 3L model as a theoretical basis. Survey and document analyses focused on the effects observable in state and private forests. In state forests, all public or state forest enterprises were able to reach goals of multifunctionality and profitablity by prioritizing marketable goods. Sustaining forest stands is important, but it is met differently in practice. Performance in private forests is much weaker and the influence of ministry departments or sectors is weak. In conclusion, the potential for a new, stronger role of public forest administration exists: (i) the supply of marketable and nonmarketable goods could be increased, whereas securing sustained forest stands remains a permanent challenge; (ii) efficiency and profits could be improved if internal and external pressures grow; and (iii) joining forces of forestry actors could strengthen the currently weak political role and enable a strong forestry representative to emerge in the future.
Numerical investigation of nonlinear fluid–structure interaction dynamic behaviors under a general Immersed Boundary-Lattice Boltzmann-Finite Element method
Authors: Gong Chun-Lin , Fang Zhe , Chen Gang
Published: April 2018

A numerical approach based on the immersed boundary (IB), lattice Boltzmann and nonlinear finite element method (FEM) is proposed to simulate hydrodynamic interactions of very flexible objects. In the present simulation framework, the motion of fluid is obtained by solving the discrete lattice Boltzmann equations on Eulerian grid, the behaviors of flexible objects are calculated through nonlinear dynamic finite element method, and the interactive forces between them are implicitly obtained using velocity correction IB method which satisfies the no-slip conditions well at the boundary points. The efficiency and accuracy of the proposed Immersed Boundary-Lattice Boltzmann-Finite Element method is first validated by a fluid–structure interaction (F-SI) benchmark case, in which a flexible filament flaps behind a cylinder in channel flow, then the nonlinear vibration mechanism of the cylinder-filament system is investigated by altering the Reynolds number of flow and the material properties of filament. The interactions between two tandem and side-by-side identical objects in a uniform flow are also investigated, and the in-phase and out-of-phase flapping behaviors are captured by the proposed method.
WHAT HAPPENS TO THE LABOR SUPPLY AND SCHOOLING OF THE CHILDREN LEFT BEHIND BY TEMPORARY MIGRANTS?
Authors: BOOTH ALISON , TAMURA YUJI
Published: April 2018

Using Vietnamese panel data, we investigate how a father’s temporary migration is associated with the labor supply and human capital investment of his child left behind. Our analysis shows that a longer absence of a father is associated with more housework and less education of his son if the boy is at an age for primary or lower secondary schooling.
Partially massless theory in three dimensions and self-dual massive gravity
Authors: Galviz Daniel , Khoudeir Adel
Published: April 2018

Partially massless theory in three dimensions is revisited and its relationship with the self-dual massive gravity is considered. The only mode of the partially massless theory is shown explicitly through an action for a scalar field on (A)dS background. This fact can be generalized to higher dimensions. This degree of freedom is altered when a triadic Chern–Simons is introduced, giving rise to the self-dual massive gravity on (A)dS background. We present another physical system with partially massless symmetry and its connection with topologically massive gravity is discussed.
Global Riemann solvers for several 3 × 3 systems of conservation laws with degeneracies
Authors: Shen Wen
Published: April 2018

We study several [Formula: see text] systems of conservation laws, arising in the modeling of two-phase flow with rough porous media and traffic flow with rough road condition. These systems share several features. The systems are of mixed type, with various degeneracies. Some families are linearly degenerate, while others are not genuinely nonlinear. Furthermore, along certain curves in the domain, the eigenvalues and eigenvectors of different families coincide. Most interestingly, in some suitable Lagrangian coordinate, the systems are partially decoupled, where some unknowns can be solved independently of the others. Finally, in special cases, the systems reduce to some [Formula: see text] models, which have been studied in the literature. Utilizing the insights gained from these features, we construct global Riemann solvers for all these models. Possible treatments on the Cauchy problems are also discussed.
Leveraging Variable Elimination for Efficiently Reasoning about Qualitative Constraints
Authors: Sioutis Michael , Long Zhiguo , Li Sanjiang
Published: April 2018

We introduce, study, and evaluate a novel algorithm in the context of qualitative constraint-based spatial and temporal reasoning that is based on the idea of variable elimination, a simple and general exact inference approach in probabilistic graphical models. Given a qualitative constraint network [Formula: see text], our algorithm utilizes a particular directional local consistency, which we denote by [Formula: see text]-consistency, in order to efficiently decide the satisfiability of [Formula: see text]. Our discussion is restricted to distributive subclasses of relations, i.e., sets of relations closed under converse, intersection, and weak composition and for which weak composition distributes over non-empty intersections for all of their relations. We demonstrate that enforcing [Formula: see text]-consistency in a given qualitative constraint network defined over a distributive subclass of relations allows us to decide its satisfiability, and obtain similar useful results for the problems of minimal labelling and redundancy. Further, we present a generic method that allows extracting a scenario from a satisfiable network, i.e., an atomic satisfiable subnetwork of that network, in a very simple and effective manner. The experimentation that we have conducted with random and real-world qualitative constraint networks defined over a distributive subclass of relations of the Region Connection Calculus and the Interval Algebra, shows that our approach exhibits unparalleled performance against state-of-the-art approaches for checking the satisfiability of such constraint networks.
An Approach for Automatic Categorization of Arabic Normative Provisions
Authors: Berrazega Ines , Faiz Rim
Published: April 2018

This paper studies the problem of automatic categorization of Arabic normative provisions. An automatic categorization approach based on a semantic annotation model is proposed. Coupling a taxonomy of Arabic normative provisions’ categories, an Arabic normative terminological base and a rule-based semantic annotator, the proposed semantic annotation model enables the automatic categorization of normative provisions in Arabic legal texts. The robustness and the language independency of the proposed approach are also studied. Robustness is measured with the comparison of the constructed model against Machine Learning (ML) approaches. The language independency level is evaluated through the adaptation of the proposed model to the French language. The performance of the approach is evaluated in terms of Precision, Recall and F-score. The obtained results for the different experiments are very promising.
Skein relations for spin networks, modifed
Authors: Kocik Jerzy
Published: April 2018

An alternative framework underlying connection between tensor [Formula: see text]-calculus and spin networks is suggested. New sign convention for the inner product in the dual spinor space leads to a simpler and direct set of initial rules for the diagrammatic recoupling methods. Yet, it preserves the standard chromatic graph evaluations. In contrast with the standard formulation, the background space is that of symmetric tensor spaces, which seems to be in accordance with the representation theory of [Formula: see text]. An example of Apollonian disk packing is shown to be a source of spin networks. The graph labeling is extended to non-integer values, resulting in the complex values of chromatic evaluations.
Remarks on Chebyshev polynomials, Fibonacci polynomials and Kauffman bracket skein modules
Authors: Owczarek Robert
Published: April 2018

The Chebyshev polynomials appear somewhat mysteriously in the theory of the skein modules. A generalization of the Chebyshev polynomials is proposed so that it includes both Chebyshev and Fibonacci and Lucas polynomials as special cases. Then, since it requires relaxation of a condition for traces of matrix powers and matrix representations, similar relaxation leads to a generalization of the Jones polynomial via reinterpretation of the Kauffman bracket construction. Moreover, the Witten’s approach via counting solutions of the Kapustin–Witten equation to get the Jones polynomial is simplified in the trivial knots case to studying solutions of a Laplace operator. Thus, harmonic ideas may be of importance in knot theory. Speculations on extension(s) of the latter approach via consideration of spin structures and related operators are given.
TMD gluon distributions at small x in the CGC theory
Authors: Petreska Elena
Published: April 2018

In this paper, we review recent progress in the description of unpolarized transverse-momentum-dependent (TMD) gluon distributions at small [Formula: see text] in the color glass condensate (CGC) effective theory. We discuss the origin of the nonuniversality of TMD gluon distributions in the TMD factorization framework and in the CGC theory and the equivalence of the two approaches in their overlapping domain of validity. We show some applications of this equivalence, including recent results on the behavior of TMD gluon distributions at small [Formula: see text], and on the study of gluon saturation. We discuss recent advances in the unification of the TMD evolution and the nonlinear small-[Formula: see text] evolution of gluon distributions.
PHOTOCATALYTIC PROPERTY AND PHOTOCATALYTIC MECHANISM OF TiO2/Fe2O3 HYBRIDS FOR DEGRADATION OF ORGANIC DYES
Authors: CHEN CHUANSHENG , FANG QUN , CAO SHIYI , YAN YONGXIANG
Published: April 2018

In order to consider the performance enhancement and feasibility of practical application, this research work discussed the effects of different ions on the photocatalytic activity of TiO2/Fe2O3 hybrids in detail, involving H[Formula: see text], OH−, NH[Formula: see text], and NO[Formula: see text]. The TiO2/Fe2O3 hybrids were prepared by organic electrolyte-assisted sol–gel method under UV irradiation, and their function mechanisms were analyzed. Experiment results show that the resultant TiO2/Fe2O3 hybrids possess excellent photocatalytic activity and photocatalytic stability for degradation of organics under acid condition (pH 2–8). Notably, the NO[Formula: see text] ions could accelerate degradation of rhodamine B and methyl orange, and the recyclability of TiO2/Fe2O3 hybrids can be greatly enhanced in the co-existence of NO[Formula: see text] and NH[Formula: see text]. Meanwhile, this symbiosis of NO[Formula: see text] and NH[Formula: see text] is proven able to buffer the solution pH in photocatalysis. Furthermore, the prominent photocatalytic activity of TiO2/Fe2O3 hybrids for organic pollutants was mainly attributed to the formation of hydroxyl radicals (OH). The synthetic products show great potential applications in purification of air or wastewater that contains ammonia-nitrogen molecules.

Published: April 2018

The gradient fine-grained oxygen-boosting layer was prepared on equal channel angular processing (ECAP)-treated titanium with thermal oxidation and oxygen boost diffusion process, and tribological properties were systematically characterized. Results show that the as-prepared boosting layer consists of surface coarse-grained region, and inner fine-grained region. The corresponding thickness and mechanical properties further increase compared to those of virgin titanium. The oxygen-boosting layer reveals excellent anti-wear properties, the dominant wear mechanism of which is abrasive.
FIRST-ORDER ASYMPTOTICS OF PATH-DEPENDENT DERIVATIVES IN MULTISCALE STOCHASTIC VOLATILITY ENVIRONMENT
Authors: SAPORITO YURI F.
Published: April 2018

In this paper, we extend the first-order asymptotics analysis of Fouque et al. to general path-dependent financial derivatives using Dupire’s functional Itô calculus. The main conclusion is that the market group parameters calibrated to vanilla options can be used to price to the same order exotic, path-dependent derivatives as well. Under general conditions, the first-order condition is represented by a conditional expectation that could be numerically evaluated. Moreover, if the path-dependence is not too severe, we are able to find path-dependent closed-form solutions equivalent to the first-order approximation of path-independent options derived in Fouque et al. Additionally, we exemplify the results with Asian options and options on quadratic variation.

Published: April 2018

Motivated by physics of the Lowest Landau Level and the Quantum Hall Effect, we investigate motion of an electron in a constant background magnetic field in the [Formula: see text]-Minkowski space-time. Starting from an action invariant under the noncommutative [Formula: see text] gauge transformations, we obtain the [Formula: see text]-deformed Dirac equation. Using the perturbative approach, we calculate noncommutative corrections to energy levels, mass and the gyromagnetic ratio up to the first order in the deformation parameter [Formula: see text].
Charge Density Wave and Spin Density Wave in Two-Orbital Model for Iron-Based Superconductors
Authors: Pradhan B.
Published: April 2018

We present a mean-field theoretical model study for the coexistence of the two strongly interacting charge density wave (CDW) and spin density wave (SDW) for iron-based superconductors in the under-doped region before the onset of the superconductivity in the system. The analytic expressions for the temperature dependence of the CDW and SDW order parameters are derived by using Zubarev’s technique of double-time single particle Green’s functions and solved self-consistently. Their interplay is studied by varying both the CDW and SDW coupling constants. Further, the electronic density of states (DOS) for the conduction electrons are studied in the pure CDW and SDW states and coexistence state for the cases, where the CDW transition temperature is greater than the SDW transition temperature and vice versa, which show two gap parameters.

Published: April 2018

Objective. To examine whether hypoesthesia and chronic pain are related in patients with MS. Methods. Sixty-seven MS patients with pain and 80 persons without MS were included. Sensory functioning was tested by bedside neurological examination. Touch, joint position (dorsal column-medial lemniscus pathway), temperature sense, and pain (spinothalamic tract) were tested. Pain intensity was measured by the Colored Analogue Scale (CAS Intensity) and the Faces Pain Scale (FPS); pain affect was also measured by CAS Affect and Number of Words Chosen-Affective (NWC-A). Mood was assessed with the SCL-90 anxiety and depression subscales and the Beck Depression Inventory (BDI). Results. A significant negative relationship was found between pain intensity and the function of the dorsal column-medial lemniscal pathway, but not with the spinothalamic tract. Conclusion. In addition to the already known relation between hyperesthesia and pain, hypoesthesia for touch and joint position also seems to be related to chronic pain in MS patients.

Prosthetic rehabilitation of atrophic maxilla and large maxillary defects can be done successfully by zygomaticimplant-supportedprosthesis. Zygomatic implants are anavant-gardeto complex andinvasive-freevascularised osteocutaneous flaps, distraction osteogenesis, and the solution to flap failures. A treated case of tuberculous osteomyelitis, with a class II (Aramany’s classification) maxillary defect, reported to oral maxillofacial department, Government Dental College (RUHS-CODS).The defect in this group was unilateral, retaining the anterior teeth. The patient was previously rehabilitated with a removable maxillary obturator. Inadequate retention affected essential functions like speaking, mastication, swallowing, esthetics, and so on due to lack of sufficient supporting tissues. A fixed prosthetic rehabilitation of posterior maxillary defect was done with obturator supported with twosingle-piecezygomatic implants. At 1-yearfollow-up,the patient was comfortable with the prosthesis, and no further complaints were recorded.

Published: April 2018

Introduction. Factors that contribute to swelling and trismus are complex, and they are originated by surgical trauma. The aim of the present study was to determine whether clinical and radiographic factors could predict the level of swelling and trismus after lower third molar surgery, through longitudinal approach. Methodology. A prospective longitudinal trial was carried out. Forty-five patients of both genders with clinical and radiographic diagnosis of asymptomatic mandibular impacted third molar and with no intake of analgesic or anti-inflammatory drugs 12 h prior to surgery were recruited and evaluated in a 72 h follow-up period. A mixed repeated measures model and backward and restricted maximal likelihood methods were used to analyze the data. Results. Male gender, body mass index (BMI), the relation to the lingual and buccal walls, and age were determinants for predicting postoperative swelling and for exerting a significant influence (P<0.05). Conclusions. This study suggests the association of male gender, the relation to lingual and buccal walls, BMI, and age with measurement of swelling.

Published: April 2018

Background: The Congenital Human Cytomegalovirus Infection Prevention (CHIP) study, a randomized, blinded, placebo-controlled trial, demonstrated that the efficacy of hyperimmune globulin (HIG) was not different from that of placebo regarding transmission of cytomegalovirus (CMV) from mothers to newborns. Our aim was to analyze histologically HIG effects on placentas collected for the CHIP study. Materials and Methods: Virological and histological analyses were performed on 40 placentas from transmitter and nontransmitter HIG-treated and untreated mothers by assessing the number of CMV-positive cells, tissue viral load, tissue damage, and compensatory mechanisms. Results: The HIG and placebo groups showed no significant differences in the number of CMV-positive cells (median number in 10 fields at 10 high-power fields: 2.5 vs. 2, p = 0.969) and viral load (median load: 5 copies/5 ng vs. 10.5 copies/5 ng, p = 0.874). Regarding histological examination, the scores of parameters related to tissue damage and hypoxic parenchymal compensation were higher in transmitters except for chorangiosis, with statistically significant differences observed for chronic villitis (p = 0.007), calcification (p = 0.011), and the total score of tissue damage (p < 0.001). The HIG and placebo groups showed no significant differences for all tissue damage and compensation parameters and overall scores. Discussion: HIGs are not able to reduce placental viral load and histological damage, which was significantly associated only with infection.

Cardiac arrest occurs at a higher rate in children with heart disease than in healthy children. Pediatric basic life support and advanced life support guidelines focus on delivering high-quality resuscitation in children with normal hearts. The complexity and variability in pediatric heart disease pose unique challenges during resuscitation. A writing group appointed by the American Heart Association reviewed the literature addressing resuscitation in children with heart disease. MEDLINE and Google Scholar databases were searched from 1966 to 2015, cross-referencing pediatric heart disease with pertinent resuscitation search terms. The American College of Cardiology/American Heart Association classification of recommendations and levels of evidence for practice guidelines were used. The recommendations in this statement concur with the critical components of the 2015 American Heart Association pediatric basic life support and pediatric advanced life support guidelines and are meant to serve as a resuscitation supplement. This statement is meant for caregivers of children with heart disease in the prehospital and in-hospital settings. Understanding the anatomy and physiology of the high-risk pediatric cardiac population will promote early recognition and treatment of decompensation to prevent cardiac arrest, increase survival from cardiac arrest by providing high-quality resuscitations, and improve outcomes with postresuscitation care.

There have been few studies comparing blood pressure (BP)–related outcomes between users and nonusers of antihypertensive drugs. We constructed a population-based cohort of 492 540 Koreans aged 40 to 79 years, who had no preexisting cardiorenal diseases, from the National Health Insurance Service-Health Screening database. The primary composite outcome was death (or critical care unit admission) from cardiorenal causes, revascularization for myocardial infarction or stroke, and new-onset end-stage renal disease. Using time-dependent Cox models, we estimated hazard ratios according to BP and antihypertensive use, which were determined in each year of follow-up. Over 10 years of follow-up, the primary outcome occurred in 26 122 subjects, and 33 550 deaths were noted. Among nonusers of antihypertensives, the risk for the primary outcome increased linearly from a BP of 105/65 mm Hg, and the risk for all-cause mortality increased from a BP of 115/75 mm Hg. Among irregular users, the risk for the primary outcome increased as the BP increased >115/75 mm Hg. Among active users, the risk for the primary outcome increased in systolic BP <115 mm Hg and >135 mm Hg, and in diastolic BP <65 mm Hg and >85 mm Hg, and the risk for all-cause mortality increased in systolic BP <125 mm Hg and >135 or 145 mm Hg. In conclusion, this population-based study demonstrated that the associations between BP and adverse outcomes were J-shaped among active antihypertensive users, but linear or flat and then increasing among nonusers or irregular users.
Initial Right Ventricular Dysfunction Severity Identifies Severe Peripartum Cardiomyopathy Phenotype With Worse Early and Overall Outcomes: A 24‐Year Cohort Study

Background

Outcomes in peripartum cardiomyopathy (
PPCM
) vary. We sought to determine whether severity of left or right ventricular dysfunction (RVD) at
PPCM
diagnosis differentially associates with adverse outcomes.

Methods and Results

We conducted a single‐center retrospective cohort study of 53 patients with PPCM. The primary outcome was a composite of left ventricular assist device implantation, cardiac transplantation, or death. We used Kaplan‐Meier curves to examine event‐free survival and Cox proportional hazards models to examine associations of left ventricular (LV) ejection fraction <30%, LV end‐diastolic diameter ≥60 mm, and moderate‐to‐severe
RVD
at
PPCM
diagnosis with the primary outcome. Median (
interquartile range
) follow‐up time was 3.6 (1.4–7.3) years. Seventeen patients (32%) experienced the primary outcome, of whom 11 had moderate‐to‐severe
RVD
at time of
PPCM
diagnosis. Overall event‐free survival differed by initial
RVD
severity and
LV ejection fraction
<30%, but not by LV
end‐diastolic diameter
≥60 mm. In univariable analyses, LV ejection fraction <30% and moderate‐to‐severe
RVD
were associated with the outcome (hazard ratios [95%
confidence intervals]
of 4.85 [1.11–21.3] and 4.26 [1.47–11.6], respectively). In a multivariable model with
LV ejection fraction
<30%,
LV end‐diastolic diameter
≥60 mm, and moderate‐to‐severe
RVD
, only moderate‐to‐severe
RVD
was independently associated with the outcome (hazard ratio [95% confidence interval
]
, 3.21 [1.13–9.10]). Although most outcomes occurred within the first year, nearly a third occurred years after
PPCM
diagnosis.

Conclusions

Initial moderate‐to‐severe
RVD
is associated with a more advanced cardiomyopathy phenotype and increased risk of adverse outcomes in
PPCM
, within and beyond the first year of diagnosis. By identifying a worse
PPCM
phenotype, initial moderate‐to‐severe
RVD
may prompt earlier consideration of advanced heart replacement therapies.
Beyond Abaclat: Mass Claims in Investment Treaty Arbitration and Regulatory Governance for Sovereign Debt Restructuring
Authors: Nakajima Kei
Published: April 2018

Whereas investment treaties and arbitration rules do not usually provide any explicit provision for mass claims in investment treaty arbitration, the Tribunal in Abaclat v Argentina established a landmark jurisprudence that allowed a massive 60,000 investors to bundle and bring their claims before a single arbitral tribunal. However, its reasoning has been severely criticised for its conclusion, which apparently favours bondholder protection at the expense of financial policy leeway of defaulted sovereigns: investment arbitration may adversely affect the orderly implementation of sovereign debt restructuring. This article attempts to take a more balanced approach towards this issue, by focusing on regulatory aspects of arbitral proceedings. A ‘regulatory’ investment treaty arbitration will not only provide creditor protection by opening the door for mass claims, but will also show a deference to an orderly restructuring by closing the door if circumstances so require.

Published: April 2018

The Neotropical fauna of Mantispidae is currently composed of 106 species. We provide new distributional records of Mantispidae from Colombia and Panama. Three new species are described, one in Symphrasinae from Colombia, and two in Mantispinae from Colombia and Panama. Haematomantispa nubeculosa (Navás, 1933) and Leptomantispa axillaris (Navás, 1908) are reported from Colombia for the first time, the former being the first record of the genus in the country. New locality records for other species previously known from Colombia are also given. For Panama, we report Anchieta fasciatella (Westwood, 1867) and Trichoscelia iridella (Westwood, 1867) for the first time, the former is herein newly transferred from Plega to Anchieta. Three names Mantispa confluens Navás, 1914, n. syn., Buyda apicata Navás, 1926, n. syn., and Mantispa neotropica Navás, 1933, n. syn., are here synonymized with Buyda phthisica (Gerstaecker, 1885). Updated keys for the genera of Mantispinae, and species of genera Trichoscelia, Buyda, and Climaciella from Colombia are included. With this new information, the known species richness of Mantispidae from Colombia increases from 21 to 26, and from 16 to 19 species in Panama.
The Impact of Recent Forcing and Ocean Heat Uptake Data on Estimates of Climate Sensitivity
Authors: Lewis Nicholas , Curry Judith
Published: April 2018

Energy budget estimates of equilibrium climate sensitivity (ECS) and transient climate response (TCR) are derived based on the best estimates and uncertainty ranges for forcing provided in the IPCC Fifth Assessment Report (AR5). Recent revisions to greenhouse gas forcing and post-1990 ozone and aerosol forcing estimates are incorporated and the forcing data extended from 2011 to 2016. Reflecting recent evidence against strong aerosol forcing, its AR5 uncertainty lower bound is increased slightly. Using an 1869–82 base period and a 2007–16 final period, which are well matched for volcanic activity and influence from internal variability, medians are derived for ECS of 1.50 K (5%–95% range: 1.05–2.45 K) and for TCR of 1.20 K (5%–95% range: 0.9–1.7 K). These estimates both have much lower upper bounds than those from a predecessor study using AR5 data ending in 2011. Using infilled, globally complete temperature data give slightly higher estimates: a median of 1.66 K for ECS (5%–95% range: 1.15–2.7 K) and 1.33 K for TCR (5%–95% range: 1.0–1.9 K). These ECS estimates reflect climate feedbacks over the historical period, assumed to be time invariant. Allowing for possible time-varying climate feedbacks increases the median ECS estimate to 1.76 K (5%–95% range: 1.2–3.1 K), using infilled temperature data. Possible biases from non–unit forcing efficacy, temperature estimation issues, and variability in sea surface temperature change patterns are examined and found to be minor when using globally complete temperature data. These results imply that high ECS and TCR values derived from a majority of CMIP5 climate models are inconsistent with observed warming during the historical period.

Published: April 2018

An accessory renal artery (ARA) represents an anatomic variation which can challenge endovascular aortic aneurysm repair (EVAR). The aim of this review was to summarize the current knowledge on postoperative outcomes following ARA coverage during EVAR. We performed a systematic literature review. The MEDLINE database was searched on September 2017, and 8 relevant studies were included. The frequency of ARA in patients undergoing EVAR varied between 9.5% and 16.2%, and the frequency of ARA coverage varied between 5.2% and 9.4%. Four reports did not observe any significant changes on postoperative renal function, whereas 1 study reported an early transient increase in creatinine after ARA coverage. The occurrence of renal infarct varied from 20% to 84%. Five studies did not observe endoleaks related to ARA coverage, whereas one reported the occurrence of type II endoleaks in 3 of 18 patients who had ARA coverage. No significant change in blood pressure, mortality, and mean length of hospital stay was observed. The ARA coverage can potentially have renal and vascular consequences, but none of them were critical. Further studies may be useful to identify preoperative criteria that may help to choose the most appropriate surgical approach before ARA coverage.
