Risk factors of trauma-induced thrombotic microangiopathy-like syndrome: A retrospective analysis

Patients with trauma may develop thrombocytopenia. We encountered cases wherein patients experienced symptoms resembling thrombotic microangiopathies (TMAs) following severe trauma. As the condition of these patients did not meet the diagnostic criteria of thrombotic thrombocytopenic purpura and there was no mention of trauma among the several causes of TMAs, it was termed as “trauma-induced thrombotic microangiopathy-like syndrome” (t-TMAS). In this study, we aimed to analyze the risk factors that may affect the incidence of t-TMAS in patients with severe trauma. This retrospective study was conducted in the trauma intensive care unit at the Kyungpook National University Hospital between January 2018 and December 2019. The medical records of 1164 of the 1392 enrolled participants were analyzed. To assess the risk factors of t-TMAS, we analyzed age, sex, mechanism of trauma, abbreviated injury scale (AIS) score, injury severity score (ISS), hematological examination, and red blood cell volume transfused in 24 hours. Among the 1164 patients, 20 (1.7%) were diagnosed with t-TMAS. The univariate analysis revealed higher age, ISS, and myoglobin, lactate, creatine kinase-myocardial band (on admission), creatine phosphokinase, lactate dehydrogenase (LDH), and lactate (day 2) levels in the t-TMAS group than in the non-t-TMAS group. The red blood cell volume transfused in 24 hours was higher in the t-TMAS group than in the non-t-TMAS group. t-TMAS was more common in patients with injuries in the chest, abdomen, and pelvis (AIS score ≥3) than in those with head injuries (AIS score ≥3) alone. The higher the sum of AIS scores of the chest, abdomen, and pelvis injuries, the higher the incidence of t-TMAS. Multivariate analysis revealed age, ISS, and LDH level (day 2) to be independent predictors of t-TMAS. Trauma surgeons should consider the possibility of t-TMAS if thrombocytopenia persists without any evidence of bleeding, particularly among older patients with multiple severe torso injuries who have high LDH levels on day 2. Early diagnosis and treatment of t-TMAS could improve patients’ prognosis.
Impact of pit latrines on drinking water contaminations in Khyber Pakhtunkhwa, Pakistan

ABSTRACT Pit latrines are projected as a safe method of excreta disposal without considering its potential impact on groundwater contamination. To understand the possible link between pit latrines and groundwater quality, two villages using pit latrines and groundwater were purposely selected in Khyber Pakhtunkhwa, Pakistan. In the targeted villages, the numbers of pit latrines and groundwater wells, their depth, subsoil strata, distance between them, year of establishment, and design were determined. Drinking water samples from the two villages (Kot and Takht-e-nasrati) were collected and analyzed for coliform, nitrates, and nitrites. Groundwater contamination in both villages was confirmed possibly due to pit latrines, particularly in the permeable soil profile. Also, it was observed that local communities are often ready to take remedial measures once they understand the potential link between pit latrines and groundwater contamination and the associated health risks.
VLTI-MATISSE chromatic aperture-synthesis imaging of η Carinae’s stellar wind across the Brα line

Context. Eta Carinae is a highly eccentric, massive binary system (semimajor axis ~15.5 au) with powerful stellar winds and a phase-dependent wind-wind collision (WWC) zone. The primary star, η Car A, is a luminous blue variable (LBV); the secondary, η Car B, is a Wolf-Rayet or O star with a faster but less dense wind. Aperture-synthesis imaging allows us to study the mass loss from the enigmatic LBV η Car. Understanding LBVs is a crucial step toward improving our knowledge about massive stars and their evolution. Aims. Our aim is to study the intensity distribution and kinematics of η Car’s WWC zone. Methods. Using the VLTI-MATISSE mid-infrared interferometry instrument, we perform Brα imaging of η Car’s distorted wind. Results. We present the first VLTI-MATISSE aperture-synthesis images of η Car A’s stellar windin several spectral channels distributed across the Brα 4.052 μm line (spectral resolving power R ~ 960). Our observations were performed close to periastron passage in February 2020 (orbital phase ~ 14.0022). The reconstructed iso-velocity images show the dependence of the primary stellar wind on wavelength or line-of-sight (LOS) velocity with a spatial resolution of 6 mas (~14 au). The radius of the faintest outer wind regions is ~26 mas (~60 au). At several negative LOS velocities, the primary stellar wind is less extended to the northwest than in other directions. This asymmetry is most likely caused by the WWC. Therefore, we see both the velocity field of the undisturbed primary wind and the WWC cavity. In continuum spectral channels, the primary star wind is more compact than in line channels. A fit of the observed continuum visibilities with the visibilities of a stellar wind CMFGEN model (CMFGEN is an atmosphere code developed to model the spectra of a variety of objects) provides a full width at half maximum fit diameter of the primary stellar wind of 2.84 ± 0.06 mas (6.54 ± 0.14 au). We comparethe derived intensity distributions with the CMFGEN stellar wind model and hydrodynamic WWC models.
Georeferencing of adolescents with malocclusion in a capital of Southern Brazil

The aim of this study was to analyze the prevalence and to georeference the malocclusion traits in adolescents in the city of Curitiba, Paraná, Brazil. Data from a previous cross-sectional study with 538 adolescents aged 10 to 14 years were used. In addition, the following variables were used: gender, Health District (HD) of residence, and presence and malocclusion traits. Fisher’s Exact Test, georeferencing, and kernel mapping were used for data evaluation. Malocclusion was observed in 52.4% of individuals, and the most prevalent occlusal trait was deep bite (22.7%), followed by excessive overjet (19.9%), anterior crowding (8.0%), posterior crossbite (6.5%), anterior open bite (4.8%), and anterior crossbite (1.7%). Malocclusion was not associated with gender (p = 0.389) or HD (p = 0.079). However, when stratified by gender, the deep bite prevailed among male. The highest malocclusion trait’s prevalence was observed in the HDs of Cajuru, Pinheirinho, Boa Vista, and Cidade Industrial de Curitiba. Despite the absence of significant differences in relation to gender and HD, the prevalence of malocclusion traits in the sample studied was high, especially for deep bite. Additionally, georeferencing proved to be useful for identifying the distribution of malocclusion in Curitiba.
Management Patterns and Outcomes for Intravitreal Injection–Related Endophthalmitis

Purpose: This work describes the clinical management and outcomes in cases of presumed infectious endophthalmitis following intravitreal injection at a tertiary academic medical center. Methods: A retrospective review took place of eyes that presented to the Duke Eye Center over a 9-year period and were diagnosed with intravitreal injection–related endophthalmitis. Clinical presentation, management, microbiologic yield, visual outcomes, and complications were abstracted from medical records. Results: Of 23 eyes diagnosed with postinjection endophthalmitis, 52.2% underwent anterior chamber tap (33.3% of which first underwent dry needle vitreous tap), 47.8% underwent needle vitreous tap, 17.4% underwent neither, and none underwent pars plana vitrectomy (PPV) for initial management. Subsequent PPV was performed in 6 eyes (26.1%). Mean visual acuity (VA) improved by 50 Early Treatment Diabetic Retinopathy Study letters at 6 months. Eyes that underwent initial anterior chamber tap had worse presenting VA than those that did not (P = .01). Eyes undergoing subsequent PPV had worse VA at presentation (P = .02) and at 6 months (P < .001). Eyes presenting with VA of hand motion (20/8000) or worse were more likely to undergo subsequent PPV (P = .02). Conclusions: Eyes with intravitreal injection–related endophthalmitis presenting with VA of hand motion or worse were more likely to undergo subsequent PPV. Future studies with larger cohorts may reveal whether earlier vitrectomy should be considered in these patients.
CFD study of Convective Heat Transfer of Water Flow Through Micro-Pipe with Mixed Constant Wall Temperature and Heat Flux Wall Boundary Conditions

The dissipation of heat in tiny engineering systems can be achieved with fluid flow through micro pipes. They have the advantage of less volume to large surface ratio convective heat transfer. There are deep-rooted analytical relations for convective heat transfer available for fluid flow through macro size pipes. But differences exist between the convective heat transfer for fluid flow through macro and micro pipes. Therefore, there is a good scope of work in micro convection heat transfer to study the mechanism of fundamental flow physics. There have been studies with either constant heat flux wall boundary conditions or constant wall temperature boundary conditions with constant and variable property flows. In this article, first, the numerical simulations are validated with the experimental data for 2D axisymmetric conventional pipe with pipe diameter of 8 mm is taken with laminar, steady, and single-phase water flows with constant wall heat flux boundary condition of 1 W/cm2. The computed Nusselt number is compared to the experimental results at different Reynolds numbers of 1350, 1600 and 1700. In the next study, three-dimensional micropipe laminar flow is studied numerically using water with an inlet velocity of 3 m/s and pipe diameter of 100 µm. The mixed wall boundary conditions with upper half pipe surface subjecting to constant wall temperature of 313 K and lower half surface subjecting to 100 W/cm2 are used in the simulations. The focus of research would be to consider the effect of temperature-dependent properties like thermal conductivity, viscosity, specific heat, and density (a combined effect we call it as variable properties) on micro-pipe flow characteristics like Nusselt number at mixed wall boundary conditions and compare it with the constant property flows. The conventional pipe showed no significant difference with variable and constant property flows with different Reynolds numbers. On contrary the flow through 3D micropipe shows that the Nusselt number with variable property flows is less as compared to the constant property flows.
Supercritical Methane Diffusion in Shale Nanopores: Effects of Pressure, Mineral Types, and Moisture Content

Using molecular dynamics, we simulated the diffusion behavior of supercritical methane in shale nanopores composed of different matrix mineral types (organic matter, clay, and calcite). We studied the effects of pore size, pore pressure, and moisture content on the diffusion process. Our results show that confined methane molecules diffuse more rapidly with increases in pore size and temperature but diffuse slowly with an increase in pressure. Anisotropic diffusion behavior is also observed in directions parallel and perpendicular to the basal surfaces of nanoslits. We also found that mineral types composing the pore walls have a prominent effect on gas diffusion. The perfectly ordered structure and ultrasmooth surface of organic matter facilitate the transport of methane in dry pores, even though its adsorption capability is much stronger than that of inorganic minerals. Moisture inhibits methane diffusion, but this adverse effect is more evident in organic pores because water migrates in the form of clu.
Of Forking Paths and Tied Hands: Selective Publication of Findings, and What Economists Should Do about It

A key challenge for interpreting published empirical research is the fact that published findings might be selected by researchers or by journals. Selection might be based on criteria such as significance, consistency with theory, or the surprisingness of findings or their plausibility. Selection leads to biased estimates, reduced coverage of confidence intervals, and distorted posterior beliefs. I review methods for detecting and quantifying selection based on the distribution of p-values, systematic replication studies, and meta-studies. I then discuss the conflicting recommendations regarding selection result ing from alternative objectives, in particular, the validity of inference versus the relevance of findings for decision-makers. Based on this discussion, I consider various reform proposals, such as deemphasizing significance, pre-analysis plans, journals for null results and replication studies, and a functionally differentiated publication system. In conclusion, I argue that we need alternative foundations of statistics that go beyond the single-agent model of decision theory.
Spontaneous Emission Measurements of Selected Alkali Radicals during the Combustion of a Single Biomass Pellet

Spontaneous emission intensities of Na*, Ca*, and K* during the combustion of single wood and straw pellets doped with known concentrations of Na, Ca, and K were measured using optical bandpass filters mounted on an intensified charge-coupled device camera. The impregnated biomass pellets were suspended in a natural gas flat flame at 750 and 1000 °C. Before the pellets were made, the biomass samples were washed and soaked to demineralize and doped with different concentrations of Na, Ca, and K (0.5, 2, and 5 wt %). During the experiments, the temperature at the center of the pellets was measured with a thermocouple and the combustion stages were identified with the help of the temperature derivative. The results reveal that, at the lower gas temperature, the emission of the selected alkalis is marginal, in agreement with previous studies. At the higher gas temperature, the emission profiles reveal that K and Na are released distinctively in the volatile combustion and char combustion stages. The presence .
Temporal permeability: Socio-historical influences on mothering occupations

ABSTRACT Using a constructivist grounded theory approach, this study explored the decision-making processes mothers employ to negotiate everyday interactions with their young children. Twelve mothers of typically developing children aged 2-6 years participated in two in-depth interviews. A total of 22 interview transcripts were analyzed using grounded theory techniques with the end goal of constructing a theoretical framework of parental decision-making. This paper describes one part of the findings of this larger study in relation to the socio-historical context influencing mothering occupations. Specifically examined were how these occupations are similar to or different from those in the parent’s family of origin and parent identified situational factors leading to these similarities and differences. The findings suggest that mothers’ responses in diverse settings are best understood as transactional relationships among the mother’s historical context (past) including predispositions for ways to act (such as a tendency to hold a particular attitude or act in a particular way), challenges encountered in the present moment, and a strong desire to provide a successful future for their children. This “temporal permeability” of mothering occupations highlights the need to understand parenting occupations more holistically rather than as a snapshot in time.
What You Want Is Not Always What You Get: Gender Differences in Employer-Employee Exchange Relationships during the COVID-19 Pandemic

Relational Inequality Theory (RIT) argues that relational claims-making- the process of employer-employee exchange relationships explicitly regarding negotiations over resources and rewards- is the central mechanism that produces social inequalities at work. Yet, the COVID-19 pandemic has significantly affected employees and employers, possibly altering their behavior in relational claims-making. Hence, this paper aims to explore if long-standing gender inequalities in employer-employee exchange relationships have reproduced or changed during the COVID-19 pandemic. It is examined (1) whether women and men differ in their response to the pandemic regarding expected employer support with further training to work from home (WFH) and (2) whether employers’ decisions on adequate support depend on employees’ gender. The hypotheses were tested using a linked employer-employee dataset (LEEP-B3) with information on German employees’ working conditions before and during COVID-19. OLS regression models predicted no gender differences in training expectations. However, women are more likely to be provided with less training than they expect from their employers. Thus, employers’ decision-making has not been altered, but gender remains an important determinant in relational claims-making, thereby reproducing gender inequalities. Finally, the workforces’ pre-COVID-19 gender ideologies predicted whether mechanisms are mitigated or enhanced. Hence, these findings underline the crucial role of the workplace context in which employer-employee exchange relationships are embedded.
Two stages of Late Carboniferous to Triassic magmatism in the Strandja Zone of Bulgaria and Turkey

Abstract Although Variscan terranes have been documented from the Balkans to the Caucasus, the southeastern portion of the Variscan Belt is not well understood. The Strandja Zone along the border between Bulgaria and Turkey encompasses one such terrane linking the Balkanides and the Pontides. However, the evolution of this terrane, and the Late Carboniferous to Triassic granitoids within it, is poorly resolved. Here we present laser ablation – inductively coupled plasma – mass spectrometry (LA-ICP-MS) U–Pb zircon ages, coupled with petrography and geochemistry from the Izvorovo Pluton within the Sakar Unit (Strandja Zone). This pluton is composed of variably metamorphosed and deformed granites which yield crystallization ages of c. 251–256 Ma. These ages are older than the previously assumed age of the Izvorovo Pluton based on a postulated genetic relationship between the Izvorovo Pluton and Late Jurassic to Early Cretaceous metamorphism. A better understanding of units across the Strandja Zone can now be achieved, revealing two age groups of plutons within it. An extensive magmatic episode occurred c. 312–295 Ma, and a longer-lived episode between c. 275 and 230 Ma. Intrusions associated with both magmatic events were emplaced into pre-Late Carboniferous basement, and were overprinted by Early Alpine metamorphism and deformation. These two stages of magmatism can likely be attributed to changes in tectonic setting in the Strandja Zone. Such a change in tectonic setting is likely related to the collision between Gondwana-derived terranes and Laurussia, followed by either subduction of the Palaeo-Tethys Ocean beneath Laurussia or rifting in the southern margin of Laurussia, with granitoids forming in different tectonic environments.
The correlation between metacognitive skills and scientific attitudes towards the retention of male and female students in South Sulawesi, Indonesia

This was quantitative correlational research, which investigated the correlation between metacognitive skills and scientific attitudes towards the retention of male and female students in South Sulawesi, Indonesia. The research sample was biology education students in the second semester, with 104 students consisting of 47 males and 57 females. The instruments employed in this study were those for assessing metacognitive skills, scientific attitudes, and retention. Metacognitive skills and retention were measured using essay tests, while scientific attitudes were measured using observation sheets. The results indicated that the value of the simultaneous contribution of metacognitive skills and scientific attitudes towards to the retention of female students was higher than that of male students. The effective contributions of metacognitive skills and scientific attitude towards male students' retention were 3.33% and 24.67%. Metacognitive skills and scientific attitudes both contribute 14.5% and 17.2%, respectively, to female students’ retention.
A New Hydrologic Sensitivity Framework for Unsteady‐State Responses to Climate Change and Its Application to Catchments With Croplands in Illinois

Climate change has been concerned as a trigger of hydrologic changes around the world. Budyko framework was widely used in hydrologic sensitivity analyses on the steady‐state water balance. The unsteady‐state responses, for example the inter‐annual hydrologic sensitivity, were not well investigated, especially for catchments influenced by croplands as that exist in Illinois in the United States. We propose a new hydrologic sensitivity framework for the unsteady‐state condition, together with a new hydrological model, to investigate the impact of croplands on the hydrologic sensitivity. In addition to the Budyko‐type relationship between the annual evapotranspiration ratio (E/P) and the aridity index (Ep/P), this framework incorporates the empirical relationship between the annual storage change ratio (ΔS/P) and Ep/P into sensitivity coefficients. The required data of annual E/P and ΔS/P could be obtained from observation and hydrological models. In particular, the bcd‐αK model is newly developed from the existing bcd model in considering croplands in Illinois, which includes only five parameters while capturing major hydrological processes for catchments with croplands. Results show that the annual E/P, ΔS/P and Q/P in 12 studied catchments have significant linear relationships with Ep/P. The annual runoff is much more sensitive to the change in precipitation than to the change in potential evapotranspiration. The traditional steady‐state analysis overestimates the sensitivity of the evapotranspiration to the change in the precipitation for the unsteady‐state condition and underestimates the variability of sensitivity coefficients among catchments.
Drivers of Subseasonal Forecast Errors of the East African Short Rains

The ‘short rains’ in East Africa from October to December have significant year‐to‐year variability. Their abundance or deficiency is often associated with floods or droughts for which early warning is crucial, though even in normal seasons skillful forecasts facilitate planning and preparedness. Here we study the relationship between initial‐state sea surface temperatures and subseasonal rainfall forecast errors in the European Center for Medium‐Range Weather Forecasts model in the region. We demonstrate that the initial mode of the Indian Ocean Dipole (IOD) is a partial control on the rainfall error in weeks 3–4. This relationship is also clear on the seasonal scale, exemplified by too‐wet forecasts during the 2015 season when the IOD was positive, and too‐dry forecasts in 2010 when it was negative. Our results provide an entry point for model improvement, and we show that a priori forecast corrections based on the initial IOD index are feasible.
Understanding students’ motivation in L2 collaborative writing

Although research about the potential learning outcome of collaborative writing in L2 or foreign language education has proliferated in the last few decades, little is known about students’ motivation in collaborative writing. This case study seeks to explore higher-proficiency (HP) students’ motivation in L2 collaborative writing, as well as factors influencing their motivation. The findings reveal that students with similar proficiency (HP) could have different levels of motivation, which may affect their participation. This study also found that knowledge of collaborative writing, previous beliefs and experiences of pair/group work, and perceived value of the role in the partnership were three major factors that influence students’ motivation in collaborative writing. This study makes several recommendations from a motivational perspective about how best to implement collaborative writing tasks in L2 classes.
