Abstract

Introduction
Gastric leak post laparoscopic sleeve gastrectomy (LSG) is a severe complication that has been reported in 1.5–3% of cases. Management algorithms of leak exist; however, no known factors predict the time to resolution. This study aims to share outcomes of our management algorithm of post LSG leak, including the rate of resolution, complications, admission to the intensive care unit, conversion to other techniques, and mortality. To determine if any factors can predict the resolution time.

Methods
A retrospective analysis of patients who had LSG leaks and was managed in the main tertiary center in Qatar (January 2012–December 2017).

Results
A total of seventy-three patients had post LSG leaks. Fifty-six (76.7%) underwent LSG outside our center. Thirteen leaks (17.8%) were after revisional LSG. Laparoscopic exploration was performed in twenty patients (27.4%) and feeding jejunostomy in nine patients (12.3%). Patients were followed up for 12 months. All healed within 8.8 ± 0.72 weeks. The resolution rate was (97.1%) without surgical conversion, while two patients required fistulo-jejunostomy. No patient died. Complications occurred; re-leak (14.9%) and splenic abscess (2.9%). Patients on jejunal feeding had shorter resolution time (HR = 2.7, P = 0.018), while patients on total parenteral nutrition and post-endoscopic dilatation had 66% and 50% increases in the resolution time; (HR = 0.34, P = 0.026) and (HR = 0.5, P = 0.047), respectively.

Conclusion
Management of post-LSG leak is multimodal. Our clinical experience demonstrated less urge to perform extensive surgical interventions. Patients on enteral feeding had shorter resolution time while patients with sleeve stricture had a longer time to resolution.

Abstract

Purpose
The extent to which smoking is associated with thyroid stimulating hormone (TSH), free thyroxine (FT4), and free triiodothyronine (FT3) when taking account of clinical variables including alcohol consumption is unclear. We aimed to determine associations of TSH, FT4, and FT3 levels with current smoking.

Methods
A cross-sectional study was performed in 5766 euthyroid participants (Prevention of Renal and Vascular End-Stage Disease cohort). Current smoking was determined by self-report, categorized as never, former, and current (≤20 and >20 cigarettes per day). Smoke exposure was determined by urinary cotinine.

Results
Current smoking of ≤20 and >20 cigarettes per day was associated with lower TSH and higher FT3 levels. FT4 levels were higher in subjects smoking <20 cigarettes per day vs. never and former smokers. Current smokers also consumed more alcohol. Multivariable linear regression analyses adjusted for age, sex, anti-TPO autoantibody positivity, alcohol consumption, and other variables demonstrated that lower TSH, higher FT4 and higher FT3 were associated with smoking ≤20 cigarettes per day vs. subjects who never smoked (P < 0.001, P = 0.018, and P < 0.001, respectively) without a further significant incremental effect of smoking >20 cigarettes per day. In agreement, TSH was inversely, whereas FT4 and FT3 levels were positively associated with urinary cotinine (P < 0.001 for each). In contrast, alcohol consumption >30 g per day conferred higher TSH and lower FT3 levels.

Conclusions
Cigarette smoking is associated with modestly higher FT4 and FT3, and lower TSH levels, partly opposing effects of alcohol consumption.

Published: November 2019

AbstractThis study aimed at exploring the formation mechanism of mathematics self-concept of left-behind children and the influence mechanism of mathematics self-concept on their mathematics achievement. In study 1, the formation mechanism of mathematics self-concept was examined using multilevel analyses of 874 left-behind children. The results showed that (1) the individual mathematics achievement of left-behind children had a significant positive predictive effect on mathematics self-concept, Chinese achievement had a significant negative predictive effect on mathematics self-concept, and the class-average mathematics achievement had no significant effect on mathematics self-concept; and (2) when left-behind children were the majority group, there was an assimilation effect on downward interpersonal social comparison. When left-behind children were the minority group, there was a contrast effect on upward intergroup social comparison. In study 2, the influence mechanism of mathematics self-concept of 585 left-behind children was investigated with a tracking research. The results suggested that (1) Time 1 mathematics self-concept had significant effects on Time 2 mathematics school engagement at between-group and within-group levels; and (2) Time 2 mathematics school engagement played a partial mediating role between Time 1 mathematics self-concept and Time 2 mathematics achievement at the within-group level. These results indicate that the formation and influence mechanism of mathematics self-concept of left-behind children is influenced by contextualized characteristics.

Abstract
Tight sandstone gas (hereafter “tight gas”) has become a subject of unconventional gas exploration globally. The large-scale development and use of tight gas resources in the USA, in particular, facilitated the rapid rebound of natural gas production in the USA, in addition to driving the rapid development of tight gas worldwide. In the eastern Ordos Basin, the Upper Paleozoic feature includes multiple layers of gas, a shallow depth, and notable potential for exploration and development. However, the reservoirs in the area are relatively tight, exhibit strong heterogeneity, and possess a complex micropore structure, thus restricting the effective economic development of oil and gas. Thus, research on the primary parameters controlling pore throat structure and the seepage capability of low-permeability reservoirs will be beneficial for the efficient exploration and development of natural gas in the eastern Ordos Basin. The parameters of reservoir porosity and percolation ability, as well as permeability, were analyzed using systematic sampling of the of the Upper Paleozoic Benxi, Taiyuan, and Shanxi Formations in the eastern Ordos Basin, constant-rate mercury injection experiments, nuclear magnetic resonance analysis, and gas–water-phase experimental studies. The results indicate that reservoir porosity is controlled by the effective pore volume and number, whereas permeability is controlled by the largest throat radius, rather than the average. The effective pore volume controls the movable fluid saturation, while reservoir percolation capability is controlled by the effective pore volume, irreducible water saturation, and size of the gas–water two-phase seepage zone.

Abstract

Objectives
Adolescents with autism spectrum disorder (ASD) display a variety of verbally aggressive, physically aggressive, and destructive behaviors. Meditation on the Soles of the Feet (SoF) as an informal mindfulness-based practice has been effective in managing aggressive behaviors in adolescents with ASD. The aim of this study was to assess its effectiveness and social validity in a Chinese context.

Methods
Mothers of three Chinese adolescents with ASD were taught a basic foundational meditation practice, followed by instructions in the SoF practice. Once proficient in these two practices, the mothers taught their adolescents with ASD to use SoF for triggers of their aggressive and destructive behaviors. The mothers rated the social validity of the SoF practice.

Results
Visual analysis and weighted average Tau-U scores across participants showed that the SoF practice had a very strong effect on reducing the verbally aggressive, physically aggressive, and destructive behaviors of the three adolescents.

Conclusions
Data regarding effectiveness and social validity indicated that the SoF practice was effective and socially valid as a self-management practice for aggressive and destructive behavior of adolescents with ASD. Further studies of the SoF practice are needed to validate its effectiveness for Chinese children with ASD.

Published: November 2019

Abstract
The aim of the paper was to study how the process of aromatisation with marjoram affected the composition of volatile fraction and antioxidant properties of rapeseed oil. Different methods of aromatisation were used: direct addition of marjoram essential oil, classical macerations of marjoram herb, and maceration assisted with ultrasound or microwave. The dominant aromatic component in the volatile fraction was γ-terpinene with concentration in the range from 3.15 μg/mL (microwave assisted maceration) to 8.82 μg/mL (classic maceration with shaking). The content of this compound in the mixture of rapeseed oil with essential oil was 152.09 μg/mL. The sample aromatized by the direct addition of essential oil contained the highest amount of volatile substances but simultaneously it had the lowest antioxidant activity.
The End of History for the Board Neutrality Rule in the EU
Authors: Mukwiri Jonathan 
Published: November 2019

AbstractThis paper argues that the failed attempt to introduce a mandatory board neutrality rule into EU takeover law was an object lesson that it is difficult to enact rules that are contrary to the corporate law cultures of the majority of the Member States. It provides an account of key factors that prevented enacting a mandatory board neutrality rule in the EU: varying takeover laws and practices; conflicting management and shareholder interests; divide between exhaustive and minimum harmonisation; and varying market orientation models. It argues that as long as there are varied national corporate laws, most EU corporate law rules are bound to remain categorised as optional, unimportant, or avoidable.
The retinal choroid as an oculovascular biomarker for Alzheimer's dementia: A histopathological study in severe disease

Published: November 2019

AbstractIntroductionPrevious in vivo optical coherence tomography studies have proposed the retinal choroid as a potential oculovascular biomarker for Alzheimer's disease (AD). However, the clinical use of the choroid as a purported surrogate marker remains poorly understood. We pursued a histopathological approach to assess choroidal thickness and vascular morphology in severe disease.MethodsHuman postmortem tissues from 8 patients with AD (mean age: 80.1 ± 12.7 years) and from 11 age‐matched controls (mean age: 78.4 ± 16.57 years) were analyzed. Thickness, area, and vascularity of the retinal choroid and its sublayers were measured from the nasal and temporal quadrants of the superior retina.ResultsNasally, the choroid was thinner in the patients with AD than in the controls (22% thickness reduction; P < .001), but to our surprise, the choroid was thicker in the patients with AD than in the controls (~60% increase; P < .03) within the macula, temporally. The choroidal area was also significantly greater in the patients with AD than in the controls (~60% increase; P < .03). Choroidal thickening in AD was strongly correlated with the stromal vessel number (R2 = 0.96, P < .001).DiscussionWe found significant differences in the retinal choroid by layer and by region, nasally and temporally with respect to the optic nerve. Intriguingly, the choroid was markedly thicker in the central macular region and was strongly associated with vessel number in the stromal vascular layer. These quantified histological findings in severe disease expand our understanding of vascular pathology in AD and suggest vascularity as a potential biomarker supplementary to thickness when evaluating the retinal choroid in AD.
To Sue or Not to Sue: How Afghan Merchants Strategically Choose to Use or Avoid Courts
Authors: RAHIMI Haroun 
Published: November 2019

AbstractThis article explores how and why Afghan merchants choose to use courts or informal dispute resolution methods. It goes beyond the common corruption and inefficiency arguments, which maintain that Afghans do not use courts because they are corrupt and inefficient. It leverages rich, original data on variation of dispute resolution practices across provinces and types of disputes to gain insights into Afghan merchants’ dispute resolution decisions. In so doing, I reveal a more complex picture of commercial dispute resolution in Afghanistan. In this article, I demonstrate that Afghan merchants do choose courts when courts enforce the parties’ expectations and courts’ judgments are necessary and effective. Moreover, while Afghan merchants do prefer informal dispute resolution methods, they do so because informal methods hold important advantages over courts in the context of Afghanistan where the formal property rights system is a failure, and the business climate is highly volatile.

Published: November 2019

AbstractBoth preterm birth and early institutional deprivation are associated with neurodevelopmental impairment—with both shared and distinctive features. To explore shared underlying mechanisms, this study directly compared the effects of these putative risk factors on temperament profiles in six-year-olds: Children born very preterm (<32 weeks gestation) or at very low birthweight (<1500 g) from the Bavarian Longitudinal Study (n= 299); and children who experienced >6 months of deprivation in Romanian institutions from the English and Romanian Adoptees Study (n= 101). The former were compared with 311 healthy term born controls and the latter with 52 nondeprived adoptees. At 6 years, temperament was assessed via parent reports across 5 dimensions: effortful control, activity, shyness, emotionality, and sociability. Very preterm/very low birthweight and postinstitutionalized children showed similarly aberrant profiles in terms of lower effortful control, preterm = −0.50, 95% CI [−0.67, −0.33]; postinstitutionalized = −0.48, 95% CI [−0.82, −0.14], compared with their respective controls. Additionally, postinstitutionalized children showed higher activity, whereas very preterm/very low birthweight children showed lower shyness. Preterm birth and early institutionalization are similarly associated with poorer effortful control, which might contribute to long-term vulnerability. More research is needed to examine temperamental processes as common mediators of negative long-term outcomes following early adversity.

Published: November 2019

Abstract.Risk of climate‐related impacts results from the interaction of climate‐related hazards (including hazardous events and trends) with the vulnerability and exposure of human and natural systems. Despite the commitment of the Paris Agreement, the integrate research on climate change risk combining risk‐causing factors and risk‐bearing bodies, the regional differences in climate impacts are still missing. In this paper we provide a quantitative assessment of hazards and socioeconomic risks of extreme events, risks of risk‐bearing bodies in China under global warming of 1.5 and 2.0 °C based on future climate scenarios, and quantitative evaluation theory for climate change risk. For severe heat waves, hazards might significantly intensify. Affected population under 2.0 °C warming might increase by more than 60% compared to that of 1.5 °C. Hazards of severe droughts and floods might strengthen under Representative Concentration Pathway 8.5 scenario. Economic losses might double between warming levels of 1.5 and 2.0 °C, and the population affected by severe floods might continuously increase. Under the integrate effects of multiple disasters, the regions with high population and economic risks would be concentrated in eastern China. The scope would gradually expand to the west with socioeconomic development and intensification of extreme events. High ecological risks might be concentrated in the southern regions of the Yangtze River Basin, while the ecological risk in northern China would expand. High agriculture yield risks might be distributed mainly in south of the North China Plain, the Sichuan Basin, south of the Yangtze River, and west of Northwest China, and the risk levels might continuously increase.
Devolatilization of Subducting Slabs, Part I: Thermodynamic Parameterization and Open System Effects
Authors: Tian Meng , Katz Richard F. , Rees Jones David W. 
Published: November 2019

AbstractThe amount of H2O and CO2 that is carried into deep mantle by subduction beyond subarc depths is of fundamental importance to the deep volatile cycle but remains debated. Given the large uncertainties surrounding the spatio‐temporal pattern of fluid flow and the equilibrium state within subducting slabs, a model of H2O and CO2 transport in slabs should be balanced between model simplicity and capability. We construct such a model in a two‐part contribution. In this Part I of our contribution, thermodynamic parameterization is performed for the devolatilization of representative subducting materials—sediments, basalts, gabbros, peridotites. The parameterization avoids reproducing the details of specific devolatilization reactions, but instead captures the overall behaviors of coupled (de)hydration and (de)carbonation. Two general, leading‐order features of devolatilization are captured: (1) the released volatiles are H2O‐rich near the onset of devolatilization; (2) increase of the ratio of bulk CO2 over H2O inhibits overall devolatilization and thus lessens decarbonation. These two features play an important role in simulation of volatile fractionation and infiltration in thermodynamically open systems. When constructing the reactive fluid flow model of slab H2O and CO2 transport in the companion paper Part II, this parameterization can be incorporated to efficiently account for the open‐system effects of H2O and CO2 transport.
Machine Learning Approach to Characterize the Postseismic Deformation of the 2011 Tohoku‐Oki Earthquake Based on Recurrent Neural Network
Authors: Yamaga Norifumi , Mitsui Yuta 
Published: November 2019

AbstractPostseismic deformation following large earthquakes has generally been analyzed via viscoelastic simulations or regression analyses that employ logarithmic and/or exponential functions. Here we introduce a machine learning approach, the recurrent neural network, to more accurately forecast postseismic deformation and constrain its characteristics. We use Global Navigation Satellite System time‐series data (horizontal components) from northeastern Japan since the 2011 Tohoku‐oki megathrust earthquake to assess the feasibility of this machine‐learning approach. We perform numerical experiment to examine the accuracy of the neural network forecast, compare the results with those from regression analyses, and confirm the improved accuracy of the neural network forecast. The spatiotemporal evolution of the differences between the observation data and forecast results implies alterations in the source of postseismic deformation, which may have occurred in 2013. We can extract detailed information on the spatiotemporal evolution of postseismic signals by implementing this new machine‐learning approach.
Radio Beacon and Radar Assessment and Forecasting of Equatorial F Region Ionospheric Stability
Authors: Hysell D. L. , Milla M. A. , Kuyeng K. 
Published: November 2019

AbstractIonospheric conditions on two adjacent nights in March 2019 were observed at the Jicamarca Radio Observatory using a combination of incoherent scatter, coherent scatter, and high‐frequency (HF) radio modes. The HF data came from a network of beacons consisting of three transmitters and six receivers operating at two frequencies and deployed regionally. The HF beacons employ pseudorandom noise coding and can be used to measure group delay (pseudorange) and Doppler shift, and the time derivative of optical path length. A method for inferring volumetric estimates of electron density regionally from the HF data is described. The radar and HF data are interpreted in light of a direct numerical simulation of the ionospheric interchange instability to elucidate why convective plumes and equatorial spread F conditions occurred on one night but not the other. The numerical simulation accurately predicted whether convective plumes would develop on a given night, utilizing initial conditions and forcings derived from the incoherent scatter data. The HF data were consistent with the incoherent scatter observations and remained intelligible throughout the equatorial spread F event. Crests in the bottomside electron density associated with convective plumes at higher altitudes could be seen propagating through the region in the HF data. It should be possible to incorporate HF data in assimilative simulations of interchange instabilities in order to predict where and when individual convective plumes emerge.
