Extended thromboprophylaxis following colorectal surgery in patients with inflammatory bowel disease: a comprehensive systematic clinical review
Authors: McKechnie T. , Wang J. , Springer J. E. , Gross P. L. , Forbes S. , Eskicioglu C. 
Published: September 2019

AbstractAimPatients with inflammatory bowel disease (IBD) are at increased risk of postoperative venous thromboembolism (VTE) following major abdominal surgery. The pathogenesis is multifactorial and not fully understood. A combination of pathophysiology, patient and surgical risk factors increase the risk of postoperative VTE in these patients. Despite being at increased risk, IBD patients are not regularly prescribed extended pharmacological thromboprophylaxis following colorectal surgery. Currently, there is a paucity of evidence‐based guidelines. Thus, the aim of this review is to evaluate the role of extended pharmacological thromboprophylaxis in IBD patients undergoing colorectal surgery.MethodA search of Ovid Medline, EMBASE and PubMed databases was performed. A qualitative analysis was performed using 10 clinical questions developed by colorectal surgeons and a thrombosis haematologist. The Newcastle–Ottawa Scale was utilized to assess the quality of evidence.ResultsA total of 1229 studies were identified, 38 of which met the final inclusion criteria (37 retrospective, one case–control). Rates of postoperative VTE ranged between 0.6% and 8.9%. Patient‐specific risk factors for postoperative VTE included ulcerative colitis, increased age and obesity. Surgery‐specific risk factors for postoperative VTE included open surgery, emergent surgery and ileostomy creation. Patients with IBD were more frequently at increased risk in the included studies for postoperative VTE than patients with colorectal cancer. The risk of bias assessment demonstrated low risk of bias in patient selection and comparability, with variable risk of bias in reported outcomes.ConclusionThere is a lack of evidence regarding the use of extended pharmacological thromboprophylaxis in patients with IBD following colorectal surgery. As these patients are at heightened risk of postoperative VTE, future study and consideration of the use of extended pharmacological thromboprophylaxis is warranted.
An approximate optimization strategy using refined hybrid metamodel
Authors: Lee Kwon‐Hee , Jeong Gyung‐Il , Lee Seong‐Hyeong 
Published: September 2019

AbstractAn approximate model called metamodel or surrogate model is a mathematical model that numerically approximates response of a system during an engineering simulation process or test. The introduction of a metamodel makes it possible to express response defined in the design problem as a simple mathematical function of design variables. A metamodel can be built with response surface method (RSM), kriging, neural network, radial basis function, and so on. Each method has its advantages and disadvantages. A combined metamodel called hybrid model, ensemble model, or multiple surrogates has been developed to maximize each metamodel's strength. The hybrid model of this research includes RSM and kriging. Besides, a strategy to refine the hybrid metamodel is implemented by reducing design space. In this process, information related to Hessian is utilized for an unconstrained optimization problem, on the contrary feasibility for a constrained optimization problem. This research presents a new hybrid metamodel‐based optimization strategy called refined hybrid metamodel. Five mathematical test problems, two‐bar design, spring design, and propeller shaft design problems are solved with the suggested method, verifying its usefulness. Most of the optimal results with the proposed method are closer to exact solutions with smaller function evaluations than existing methods.

AbstractA 20‐month‐old otherwise well child with no cardiac history presented for evaluation of a recent onset cardiac murmur. His initial examination revealed significant right carotid bruit along with a transthoracic echocardiogram (ECHO) concerning for severe transverse arch hypoplasia with unusual appearance and left ventricular hypertrophy with preserved function. This report demonstrates the utility of various modalities including echo, CT, and MRI to assess vascular structures in different vascular territories in a challenging patient who underwent a satisfactory arch repair with unexpected pathology findings.
Digital Module 08: Foundations of Operational Item Analysis https://ncme.elevate.commpartners.com
Authors: Yoo Hanwook [Henry] , Hambleton Ronald K. 
Published: September 2019

AbstractItem analysis is an integral part of operational test development and is typically conducted within two popular statistical frameworks: classical test theory (CTT) and item response theory (IRT). In this digital ITEMS module, Hanwook Yoo and Ronald K. Hambleton provide an accessible overview of operational item analysis approaches within these frameworks. They review the different stages of test development and associated item analyses to identify poorly performing items and effective item selection. Moreover, they walk through the computational and interpretational steps for CTT‐ and IRT‐based evaluation statistics using simulated data examples and review various graphical displays such as distractor response curves, item characteristic curves, and item information curves. The digital module contains sample data, Excel sheets with various templates and examples, diagnostic quiz questions, data‐based activities, curated resources, and a glossary.
New net zooplankton geographical information system in the Far East seas and adjacent waters of the Pacific Ocean
Authors: Volvenko Igor V. 
Published: September 2019

AbstractMotivationI describe the GIS that is based on a new database of zooplankton collected by Juday net with a 0.1 m2 opening (0.168 mm mesh).Main types of variables containedThe average density (in milligrams per cubic metre) of plankton and their different constituents in 1° trapeziums.LocationChukchi, Bering, Okhotsk, Japan/East seas and Pacific Ocean.Time period1984–2013.Taxa studiedAll mesofauna; > 214 species of holo‐ and meroplankton.MethodsGIS creation, data analysis and literature review.Software formatAny that is capable of working with shapefiles.ResultsMaps of the spatio‐temporal distribution of plankton with various taxonomic groups and dimensions were compiled and analysed. Based on these maps and on the literature, a hypothesis was made regarding the negative correlation of the zooplankton size with temperature. It was also revealed that some fluctuations in the abundance of plankton in the Bering Sea and the ocean are in phase, whereas in the Sea of Okhotsk and the Sea of Japan the fluctuations are fully out of phase. In particular, during the transition from the light to the dark time of the day in the Sea of Okhotsk and the Sea of Japan, the density of plankton almost everywhere throughout the epipelagic zone increases; however, in the Bering Sea and the ocean, over large parts of the water area, it decreases. This means that the common practice by trophologists of attempting to replace the day‐time catch in plankton nets with the night‐time catches to assess the food reserves for fish will yield significantly different results in these waters.Main conclusionThis unique GIS could be useful to planktonologists, ichthyologists, hydrobiologists, trophologists, ecologists, biogeographers and modellers for understanding patterns and drivers of plankton diversity and biomass variations at large scales. Unfortunately, owing to lack of funding, it has not been brought to the levels of species, size classes and developmental stages that could be available in the final release.
Decolonial education and geography: Beyond the 2017 Royal Geographical Society with the Institute of British Geographers annual conference
Authors: Stanek Marcin B. 
Published: September 2019

AbstractThis review is inspired by the recent resurgence of grassroots movements aimed at the decolonisation of education. The departure point of the paper are the numerous, recent academic responses to campaigns such as Rhodes Must Fall, Why is My Curriculum White?, Why Isn't My Professor Black?, and #LiberateMyDegree. Following from there, the narrative is divided into two sections. The first part reviews theoretical approaches to decolonial education, especially those rooted in the modernity/coloniality/decoloniality paradigm. The second part analyses the ways in which geographers have applied these ideas to our discipline. The review pays particular attention to the 2017 Royal Geographical Society with the Institute of British Geographers annual conference, curated under the “Decolonising geographical knowledges” theme. I argue that as geographers, we have to continue reflecting on the meaning of decolonial praxis, especially in relation to geographical education, beyond the recent conference. To these ends, the review concludes with seven specific questions for geographers to consider in the near future.
Review: Diagnosis of Helicobacter pylori infection

Published: September 2019

AbstractEndoscopic imaging of the stomach is improving. In addition to narrow band imaging, other methods, for example, blue light imaging and linked color imaging, are now available and can be combined with artificial intelligence systems to obtain information on the gastric mucosa and detect early gastric cancer. Immunohistochemistry is only recommended as an ancillary stain in case of chronic active gastritis without Helicobacter pylori detection by standard staining, and recommendations to exclude false negative H. pylori results have been made. Molecular methods using real‐time PCR, droplet digital PCR, or amplification refractory mutation system PCR have shown a high accuracy, both for detecting H. pylori and for clarithromycin susceptibility testing, and can now be used in clinical practice for targeted therapy. The most reliable non‐invasive test remains the 13C‐urea breath test. Large data sets show that DOB values are higher in women and that the cut‐off for positivity could be decreased to 2.74 DOB. Stool antigen tests using monoclonal antibodies are widely used and may be a good alternative to UBT, particularly in countries with a high prevalence of H. pylori infection. Attempts to improve serology by looking at specific immunodominant antigens to distinguish current and past infection have been made. The interest of Gastropanel® which also tests pepsinogen levels was confirmed.
Night, light and flight: light attraction in Trichoptera
Authors: Larsson Malin , Göthberg Anders , Milberg Per 
Published: September 2019

Abstract
Artificial light is an important and necessary part of urban environments, but light can have substantial direct and indirect effects on populations of various organisms. Urban areas are often situated close to water and thus organisms dependent on water could be especially vulnerable. Trichoptera is one of the most abundant insect orders in freshwater, but its attraction to light has not been analysed in detail.
We contrasted catches in light traps and passive traps at three locations in Sweden.
The results showed that artificial light can affect Trichoptera populations. Attraction to light varied between Trichoptera species and females were more attracted than males. Day‐, evening‐ and especially night‐active species were all attracted to light. Light catches of day‐ and evening‐active Trichoptera could partly be a consequence of atypical flight activity, i.e. they are deceived to take flight when a lamp is lit during night.
In all, artificial light can alter Trichoptera populations, sex ratios and species composition. This impact should be considered when erecting and managing light sources near waterways.

Work Trajectories of Female and Male Immigrants in Spain
Authors: Carrasco Carpio Concepción , García‐Serrano Carlos , Hernanz Virginia 
Published: September 2019

AbstractThis article aims to examine in depth the work trajectories of individuals over time, in order to provide a wider perspective of the employment history of immigrants compared to native people, by gender and for more than one decade (2005–2017) in Spain. We use microdata (cohort and multivariate analysis) from the Labour Force Survey and carry out a comparison for three groups: the Spanish born in Spain, the Spanish born abroad, and the non‐Spanish born abroad. The results confirm that the non‐Spanish born‐abroad group is characterized by the existence of segmented assimilation. All foreigners suffered a loss in their work trajectories, since their employment rate in 2017 has as yet neither reached the level of the last years of the previous economic expansion nor the level of the previous cohorts at the same age.

Published: September 2019

AbstractEquine insect bite hypersensitivity (IBH) is a pruritic skin allergy caused primarily by biting midges, Culicoides spp. IBH susceptibility has polygenic inheritance and occurs at high frequencies in several horse breeds worldwide, causing increased costs and reduced welfare of affected horses. The aim of this study was to identify and validate single nucleotide polymorphisms (SNPs) associated with equine IBH susceptibility. After quality control, 33,523 SNPs were included in a Bayesian genome‐wide association study on 177 affected and 178 unaffected Icelandic horses. We report associated regions in E. caballus (ECA) 1, 3, 15 and 18, overlapping with known IBH QTLs in horses, and novel regions containing several genes, together explaining 11.46% of the total genetic variance. For validation, three SNPs on ECA 1 and ECA X (explaining the largest percentage of genetic variance) within 1‐mb genomic windows for IBH were genotyped in an independent population of 280 Exmoor ponies. The associated genomic region (152–153 mb) on ECA 1 was confirmed in Exmoor ponies and contains the AQR gene involved in splicing processes and a long non‐coding RNA. This study confirms the polygenic nature of IBH susceptibility and suggests a role of transcriptional regulatory mechanisms (e.g., alternative splicing) for IBH predisposition in these horse breeds.
Hypertension control in Argentina, in the middle of a long road
Authors: Carbajal Horacio A. , Salazar Martin R. 
Published: September 2019

AbstractIn Argentina, cardiovascular diseases are the leading cause of death and represent 1/3 of total mortality. In 2017, hypertension prevalence for inhabitants ≥18 years old was 36.3%, and its level of knowledge and control (<140/90 mm Hg) were 61% and 24%, respectively. Furthermore, 56% of people treated with antihypertensive drugs do not reach therapeutic goal. In addition to this, prevalence of other risk factors, such as sedentary lifestyle, overweight‐obesity, high blood glucose/diabetes, and high cholesterol, has worsened in the last 5 years. The governmental initiative "Less Salt More Life" intends to reduce salt consumption in the entire population and promoted a National Law, which establishes the progressive salt reduction in processed foods. This initiative is probably related to the reduction of salt use after cooking or sitting at the table, observed in the Risk Factors National Survey. Furthermore, previously published studies showed, in relatively small samples from Argentina, that populational blood pressure can be decreased and hypertension control can be improved using community‐based or multicomponent intervention programs. However, no specific designed national effort for hypertension control is now officially applied. In consequence, we believe that, in order to increase hypertension control, the effort should not focus on developing new strategies, but on quickly implementing and maintaining those local multicomponent interventions that have already proven to be effective.
A Comparison of Aggregation Rules for Selecting Anchor Items in Multigroup DIF Analysis
Authors: Huelmann Thorben , Debelak Rudolf , Strobl Carolin 
Published: September 2019

AbstractThis study addresses the topic of how anchoring methods for differential item functioning (DIF) analysis can be used in multigroup scenarios. The direct approach would be to combine anchoring methods developed for two‐group scenarios with multigroup DIF‐detection methods. Alternatively, multiple tests could be carried out. The results of these tests need to be aggregated to determine the anchor for the final DIF analysis. In this study, the direct approach and three aggregation rules are investigated. All approaches are combined with a variety of anchoring methods, such as the “all‐other purified” and “mean p‐value threshold” methods, in two simulation studies based on the Rasch model. Our results indicate that the direct approach generally does not lead to more accurate or even to inferior results than the aggregation rules. The min rule overall shows the best trade‐off between low false alarm rate and medium to high hit rate. However, it might be too sensitive when the number of groups is large. In this case, the all rule may be a good compromise. We also take a closer look at the anchor selection method “next candidate,” which performed rather poorly, and suggest possible improvements.
Classification Consistency and Accuracy With Atypical Score Distributions
Authors: Kim Stella Y. , Lee Won‐Chan 
Published: September 2019

AbstractThe current study aims to evaluate the performance of three non‐IRT procedures (i.e., normal approximation, Livingston‐Lewis, and compound multinomial) for estimating classification indices when the observed score distribution shows atypical patterns: (a) bimodality, (b) structural (i.e., systematic) bumpiness, or (c) structural zeros (i.e., no frequencies). Under a bimodal distribution, the normal approximation procedure produced substantially large bias. For a distribution with structural bumpiness, the compound multinomial procedure tended to introduce larger bias. Under a distribution with structural zeroes, the relative performance of selected estimation procedures depended on cut score location and the sample‐size conditions. In general, the differences in estimation errors among the three procedures were not substantially large.
Ground application of mating disruption against the gypsy moth (Lepidoptera: Erebidae)

Published: September 2019

AbstractThe gypsy moth, Lymantria dispar (L.) (Lepidoptera: Erebidae), is a non‐native defoliating insect that continues to expand its range in North America and undergo periodic outbreaks. In management efforts to suppress outbreaks, slow its spread and eradicate populations that arrive outside of the invaded range, aerial deployments of mating disruption tactics and pesticides are generally used. However, in some cases, such as in heavily urbanized areas or other landscapes where aerial deployments are not feasible or permitted, ground applications are required. Ground applications tend to be labour‐intensive to ensure adequate coverage. To better inform optimal deployment of ground applications of mating disruption, we measured the effectiveness of a pheromone formulation designed for ground application, SPLAT® GM, in forested areas of Virginia from 2011 to 2014 using different dosages and number of point applications. We observed that SPLAT® GM applied to the tree trunks at the dosages of 49.4 and 123.6 g AI/ha in 11 × 11 systematic grids (i.e., every 11 m) reduced male trap catch by >90% relative to untreated control plots, which based on previous studies corresponds to >95% reduction in gypsy moth mating success. Our observations suggest that ground applications of gypsy moth mating disruption can be a successful management tool when circumstances require it.
Outcomes of Waterbirth in a US Hospital‐Based Midwifery Practice: A Retrospective Cohort Study of Water Immersion During Labor and Birth

Published: September 2019

IntroductionAlthough the safety of water immersion during labor is largely supported by evidence from research, the risks to women and neonates during waterbirth are not well established. The purpose of this study was to generate evidence regarding maternal and neonatal outcomes related to water immersion in labor and during birth.MethodsA retrospective cohort study included a convenience sample of women receiving prenatal care at a nurse‐midwifery practice. Participants were categorized into 3 groups: 1) waterbirth, 2) water labor, or 3) neither. Participant characteristics, maternal outcomes, and newborn outcomes were collected at time of birth and health record abstraction. At the 6‐week postpartum visit, another maternal outcome, satisfaction with birth, was measured using the Care in Obstetrics: Measure for Testing Satisfaction (COMFORTS) scale. Analysis included effect size, descriptive statistics (sample characteristics), and maternal and neonatal group differences (analysis of variance and chi‐square) with a significance level of P < .05.ResultsWomen in the waterbirth (n = 58), water labor (n = 61), and neither (n = 111) groups were primarily white, married, and college educated and did not differ by age or education. Women in the waterbirth group were more likely to be multiparous. Nulliparous women who had a waterbirth had a significantly shorter second stage of labor than nulliparous women who did not have a waterbirth (P = .03). The most commonly cited reasons for discontinuation of hydrotherapy were maternal choice (42.6%) and need for pain medication (29.5%). Significantly more women in the waterbirth group experienced a postpartum hemorrhage, compared with water labor or neither (n = 5, n = 3, n = 1, respectively; P = .045); there was no difference in related clinical measures. Neonatal outcomes were not significantly different. Maternal satisfaction was high across all groups.DiscussionThe results of this study suggest that waterbirth, attended by qualified intrapartum care providers in hospital settings in the United States, is a reasonable option for low‐risk women and their neonates.
