Sagittal deformity of Garden type I and II geriatric femoral neck fractures is frequently misclassified by lateral radiographs

Objectives: The objective of this study was to determine the validity and inter-rater reliability of radiographic assessment of sagittal deformity of femoral neck fractures. Design: This is a retrospective cohort study. Setting: Level 1 trauma center. Patients/Participants: Thirty-one patients 65 years or older who sustained low-energy, Garden type I/II femoral neck fractures imaged with biplanar radiographs and either computed tomography or magnetic resonance imaging were included. Main Outcome Measurements: Preoperative sagittal tilt was measured on lateral radiographs and compared with the tilt identified on advanced imaging. Fractures were defined as “high-risk” if posterior tilt was ≥20 degrees or anterior tilt was >10 degrees. Results: Of 31 Garden type I/II femoral neck fractures, advanced imaging identified 10 high-risk fractures including 8 (25.8%) with posterior tilt ≥20 degrees and 2 (6.5%) with anterior tilt >10 degrees. Overall, there was no significant difference between sagittal tilt measured using lateral radiographs and advanced imaging (P = 0.84), and the 3 raters had good agreement between their measurements of sagittal tilt on lateral radiographs (interclass correlation coefficient 0.79, 95% confidence interval [0.65, 0.88], P < 0.01). However, for high-risk fractures, radiographic measurements from lateral radiographs alone resulted in greater variability and underestimation of tilt by 5.2 degrees (95% confidence interval [−18.68, 8.28]) when compared with computed tomography/magnetic resonance imaging. Owing to this underestimation of sagittal tilt, the raters misclassified high-risk fractures as “low-risk” in most cases (averaging 6.3 of 10, 63%, range 6 − 7) when using lateral radiographs while low-risk fractures were rarely misclassified as high-risk (averaging 1.7 of 21, 7.9%, range 1 − 3, P = 0.01). Conclusions: Lateral radiographs frequently lead surgeons to misclassify high-risk sagittal tilt of low-energy femoral neck fractures as low-risk. Further research is necessary to improve the assessment of sagittal plane deformity for these injuries. Level of Evidence: Level IV diagnostic study.
A numerical study of the nocturnal atmospheric boundary layer

The evolution of the structure of the atmospheric boundary layer during the cooling phase of the diurnal cycle is studied with the help of a one-dimensional numerical model. The model uses a turbulent energy equation for the determination of the eddy exchange coefficients, which also involve the local value of the Monin-Obukhov length. The surface temperature is prescribed as a function of time and the geostrophic wind is held constant. Results are presented in nondimensional form and cover a wide range of possible values for the external parameters. After several hours of cooling the inversion layer is found to reach a maximum depth, which depends strongly upon the magnitude of the geostrophic wind and, to a lesser extent, on the cooling rate of the ground surface.
Adverse Drug Reactions in Psychiatry Outpatient Department of a Tertiary Care Hospital in Western Uttar Pradesh: An Observational Study

Objective: Psychiatric disorders are chronic in nature which require medications for a long duration. These medications have been associated with many adverse events. Failure to recognize an adverse drug reaction (ADR) exposes the patient to continuing risk of ADR, leading to a significant impact on patient's quality of life. Thus, the present study carried out to identify the pattern of ADRs reported due to psychotropic medication. Methods: This was a cross-sectional study conducted to analyze ADRs reported from the psychiatry department of a tertiary care teaching hospital from October 2021 to March 2022. Findings: A total of 137 ADRs were identified from 102 patients. Majority of the ADRs were reported from antidepressants, with paroxetine being the leading offending drug. The central nervous system was most commonly affected, and dizziness (13.13%) was the most common ADR noted. On causality assessment, 97 ADRs (70.8%) were of “possible” type. Almost half of the patients with ADRs (47.5%) recovered spontaneously. No ADR encountered turned out to be fatal. Conclusion: The present study revealed that the majority of ADRs reported from psychiatry OPD were mild in nature. We reinforce the identification of ADR is crucial in the hospital setting process as it gives an insight into the risk-benefit ratio for rational use of the drug.
Teaching Inquiry With a Lens Toward Curiosity

Abstract This paper links educational psychology research about curiosity to teacher moves that are effective in an inquiry-based mathematics classroom. Three vignettes will show explicit teacher moves (staging disagreement, intriguing anecdotes, and creating a safe space) for different audiences (math majors, mathematics for liberal arts students, and future elementary school teachers) and tie them to particular studies about curiosity. The goal is to deepen our thinking about inquiry-based teaching by considering curiosity as one of the starting points of inquiry. Educational psychologists have found ample evidence that curiosity improves learning. We claim that curiosity and inquiry are deeply connected in a curiosity–inquiry cycle and become most active in a classroom that exhibits a culture of asking questions.
Instructional Conditions in Charter Schools and Students’ Mathematics Achievement Gains

Since charter school research on student achievement is mixed, many researchers and policy makers advocate looking inside the “black box” of schools to better understand the conditions under which schools of choice may be effective. We begin to address this issue with data from charter schools and a comparison group of traditional public schools. We also conduct propensity score matching at the student level to further understand achievement gains. In our analyses of these data, we find no charter school effects on students’ achievement gains. Instructional conditions, such as teachers’ focus on academic achievement, are related to mathematics gains. However, we find that our innovation measure is negatively associated with gains (when other conditions are controlled for), which suggests that innovation for innovation’s sake should not be the sole focus of schools, whether charter or not.
The Impact of Medical Injustice: Restoring Trust in Clinical Practice

Intergenerational trauma, defined as the impact of trauma on not only one generation but also the next generation, can adversely affect the integrity of patient-physician relationships [1, 2]. Racism and the structural inequity it perpetuates are one of many driving forces behind intergenerational trauma [3]. In children, families, and communities, its effects can be felt biologically, socially, and psychologically [1]. Such an effect extends itself into the cardiac health of African Americans and minority groups, resulting in disparities in most cardiac procedures and treatments, such as CABG and hypertension regulation [4]. To tailor care with a more compassionate view of Black experiences, clinicians must further their understanding of medical mistrust and its link to racial, historical, and intergenerational trauma.
Simulation of Contamination Prevention for Optical Window in Laser Ignition Systems of Large-Caliber Guns

In laser ignition systems, to ignite the propellant, the laser has to be transmitted into chamber through an optical window. If the optical window is destroyed by high pressure or high temperature or contaminated by the black powder residue, the ignition system will fail in further firings. The sapphire window can withstand the high pressure and high temperature of the ballistic cycle, but it is necessary to keep the window clean for the laser to transmit repeatedly. In modular charge systems or fully combustible cartridge cases, there is no place to put a shield window as in ammunition with stub base; thus a new contamination prevention method is put forward. In this method, the hydrodynamic force is used to divert the gas flow in a cavity located in the breech to avoid contact with the optical window and prevent it from being contaminated. To verify the effectiveness of this structure, a three-dimensional unsteady discrete phase model (DPM) coupled with an interior ballistic process was established. The simulation results indicated that the flow jet from the direct orifice was diverted, and particle debris did not contaminate the optical window due to the hydrodynamic force. Various factors influencing the contamination prevention effect were discussed, and the structure parameters were optimized.
Antidepressant and Anxiolytic Potentials of the Chewing Stick, Salvadora persica

Materials and Methods Salvadora persica stem bark was extracted with two different solvents, i.e., ethyl acetate and water, and preliminary phytochemical screening was performed. Two behavioral models were used: an elevated plus maze test (EPM) and the light and dark model test for anxiolytic parameters, and a forced swim test (FST) for antidepressant effects. Healthy mice weighing 18−40 gms were treated orally in four groups (n = 6), i.e., negative control treated with normal saline and positive control with 1 mg/kg diazepam (EPM) and 30 mg/kg fluoxetine (FST), and the test groups were treated with 500 mg/kg of aqueous and ethyl acetate Sp extract. The number of entries and duration spent in the open arm for 5 minutes were the parameters for evaluating the anxiolytic activity (EPM). Duration of immobility was measured for 5 min in the FST model. Results In EPM, both the Sp extracts significantly (p < 0.005) increased the number of entries and the time spent in the open arms and was much similar to those of diazepam. Similarly, these extracts and fluoxetine significantly (p < 0.005) decreased the immobility time in FST. Conclusion The results suggest the therapeutic potential of Salvadora persica an alternative in the management of comorbid anxiety and depression.
One way or another? Discussion disagreement and attitudinal homogeneity on social networking sites as pathways to polarization in Czechia

ABSTRACT This study focuses on social networking sites and their role in partisan-based affective polarization and political antagonism. We examine the relationship by testing variables that indicate selective exposure to counter-attitudinal and pro-attitudinal information. The results from Czech survey data (n = 2,792) collected in 2020 show a positive relationship between both perceived discussion disagreement and attitudinal homogeneity of the network to political antagonism, and a positive relationship between the perceived attitudinal homogeneity of the network and affective polarization. The results thus question the existence of a single universal social media use pattern contributing to polarization.
Supporting young children’s social emotional competence in the Republic of Georgia: a focus group study

ABSTRACT This study utilized six focus groups to explore 49 early childhood teachers’ perspectives and reported use of Pyramid Model practices to support young children’s social emotional competence in the Republic of Georgia. Constant comparison analysis was used to analyze participants’ responses. Early childhood educators described implementing some social emotional interventions and supports across tiers of the Pyramid Model in Georgian early childhood classrooms. Early childhood teachers across regions expressed the need for additional personnel, training, and social emotional resources. Implications of the findings are discussed in terms of the importance of ensuring the cultural fit of frameworks such as the Pyramid Model.
Uterine artery Doppler and endometrial blood flow in frozen embryo transfer: A cohort study

Abstract Background The implantation rate after assisted reproductive technology depends on 2 important factors, good quality embryo and endometrial receptivity. Endometrial receptivity is mainly assessed by ultrasound measurement of endometrial thickness and morphology. Objective This study aimed to investigate the relationship between uterine artery Doppler indices/endometrial perfusion and pregnancy rate. Materials and Methods This cohort study was done on 250 women who were candidates for frozen embryo transfer from January to July 2022. For assessing endometrial receptivity, we performed a Doppler ultrasound of the uterus before embryo transfer with apparently desirable endometrium (endometrial thickness ≥ 7 mm and 3 line endometrial pattern). In addition, the women were divided into 2 groups according to assisted reproductive technology outcome (clinical pregnancy), group I positive clinical pregnancy, and group II negative clinical pregnancy, and uterine artery indices and endometrial perfusion were compared between these groups. Results Uterine artery Doppler showed that the pulsatility index was significantly different between positive and negative clinical pregnancy groups, but resistance index and peak systolic velocity (PSV) did not have statistically significant differences. Also, endometrial perfusion was significantly different between the 2 groups of clinical pregnancy. Endometrial perfusion was significantly better in positive clinical pregnancy groups. Conclusion Doppler ultrasound can help to assess endometrial receptivity.
Plasmoid evolution in an extended magnetotail

The formation and evolution of a three-dimensional magnetotail plasmoid is investigated by means of a three-dimensional resistive MHD simulation. In contrast to earlier simulations, the present one takes place in a tail configuration that includes the transition from a closed field line region to an open far-tail region with a distant X line or separator. This is necessary to identify the plasmoid and to study its properties during the separation from Earth. Particular emphasis is placed on the plasma acceleration and the relative importance of pressure forces and Lorentz forces. Two distinct phases of the plasmoid evolution are analyzed, the growth, characterized by accumulation of plasma that has already been accelerated by Lorentz forces outside the plasmoid, and the severance of the plasmoid from Earth, which takes a finite amount of time, propagating from midnight toward the flanks. This phase is characterized by a decrease in plasmoid speed due to the fact that accumulation of plasma of slower speed continues near the flanks and at the leading edge, while the plasmoid becomes severed near midnight. This phase is also characterized by a complicated topological structure of the plasmoid consisting of intermingled flux tubes with different connections. The total force on the plasmoid itself is initially dominated by the pressure gradients and later by the Lorentz forces. These forces, however, do not contribute significantly to the plasmoid motion in comparison to the accumulation of momentum.
Two canonical wedge problems for the Helmholtz equation

Boundary-transmission problems for two-dimensional Helmholtz equations in a quadrant and its complement, respectively, are considered in a Sobolev space setting. The first problem of a quadrant with Dirichlet condition on one face and transmission condition on the other is solved in closed form for the case where all the quadrants are occupied by the same medium. Unique solvability can also be shown in the case of two different media up to exceptional cases of wave numbers, while the Fredholm property holds in general. In the second problem, transmission conditions are prescribed on both faces. Similar results are obtained in the one-medium case, but the two-media case turns out to be more complicated and the equivalent system of boundary pseudodifferential equations cannot be completely analysed by this reasoning.
Inhomogeneous distribution of a rigid fibre undergoing rectilinear flow between parallel walls at high Péclet numbers

We use slender-body theory to simulate a rigid fibre within simple shear flow and parabolic flow at zero Reynolds number and high Péclet numbers (weak Brownian motion). Hydrodynamic interactions of bulk fibres with the bounding walls are included using previously developed methods (Harlen, Sundararajakumar & Koch, J. Fluid Mech., vol. 388, 1999, pp. 355–388; Butler & Shaqfeh, J. Fluid Mech., vol. 468, 2002, pp. 205–237). We also extend a previous analytic theory (Park, Bricker & Butler, Phys. Rev. E, vol. 76, 2007, 04081) predicting the centre-of-mass distribution of rigid fibre suspensions undergoing rectilinear flow near a wall to compare the steady and transient distributions. The distributions obtained by the simulation and theory are in good agreement at sufficiently high shear rates, validating approximations made in the theory which predicts a net migration of the rigid fibres away from the walls due to a hydrodynamic lift force. The effect of the inhomogeneous distribution on the effective stress is also investigated.
A 2D Lattice Boltzmann Full Analysis of MHD Convective Heat Transfer in Saturated Porous Square Enclosure

A thermal lattice Boltzmann model for incompressible flow is developed and extended to investigate the natural convection flow in porous media under the effect of uniform magnetic field. The study shows that the flow behaviour is various parameters dependent. The Rayleigh number (Ra ), Hartmann number (Ha), Darcy number (Da) and the medium inclination angle from the horizontal (φ ), the magnetic field orientation (ψ) and the medium porosity (ε) effects are carried out in wide ranges encountered in industrial and engineering applications. It was found that the flow and temperature patterns change significantly when varying these parameters. To confirm the accuracy in present simulations, the present results are first validated on two test cases with and without magnetic field. A good agreement is observed by comparison with available previous works. It is found also that the lattice Boltzmann method is a reliable tool that gives a great deal of valuable information about the dynamics of buoyancy-driven flows and put on view the physics of the flow under stiff conditions.
Phenomenology of a flow around a circular cylinder at sub-critical and critical Reynolds numbers

In this work, the flow around a circular cylinder is investigated at Reynolds numbers ranging from 79 000 up to 238 000 by means of a combined acquisition system based on Temperature Sensitive Paint (TSP) and particle velocimetry. The proposed setup allows simultaneous and time-resolved measurement of absolute temperature and relative skin friction fields onto the cylinder surface and near-wake velocity field. Combination of time-resolved surface measurements and planar near-field velocity data allows the investigation of the profound modifications undergone by the wall shear stress topology and its connections to the near-field structure as the flow regime travels from the sub-critical to the critical regime. Laminar boundary-layer separation, transition, and re-attachment are analyzed in the light of temperature, relative skin friction maps, and Reynolds stress fields bringing about a new perspective on the relationship between boundary layer development and shear layer evolution. The fast-responding TSP employed allows high acquisition frequency and calculation of power spectral density from surface data. Correlation maps of surface and near-wake data provide insight into the relationship between boundary-layer evolution and vortex shedding. We find that as the Reynolds number approaches the critical state, the separation line oscillations feature an increasingly weaker spectrum peak compared to the near-wake velocity spectrum. In the critical regime, separation line oscillations are strongly reduced and the correlation to the local vorticity undergoes an overall decrease giving evidence of modifications in the vortex shedding mechanism.
Effect of Foreign Direct Investment and Trade Openness on the Poverty Alleviation in Burundi – Sub African Country: ARDL (Co-integration) Approach

International Trade and Foreign Direct Investment openness are crucial for economic growth and development. These are equally significant for developed and under-developed countries. The study’s major goal was to look at how foreign direct investment, inflation, GDP and trade openness affected the poverty alleviation in Sub-Saharan African Countries. A country where half of the population lives below the poverty. Annual data for the period 1990 to 2021 gathered from World Development Indicators database to investigate the long run & short run effects of the independent variables for the Sub-Saharan African countries by using Auto-regressive and Lag distributive (Co-integration) model. The findings revealed negative long run influence of foreign direct investment and GDP to poverty head count ratio. The shreds of Evidence also showed that FDI has not shown any distinctive effect on poverty in a shorter period. Moreover, GDP, trade openness and inflation are also effective in reducing poverty in short run. While inflation urges the investors to do more investment in production sector that reduces unemployment and poverty in the end. The study suggested the government officials, policymakers, and investors, to invest more in the poor countries. As FDI is crucial in creating jobs for the unemployed population that lead to the rise in income and living standard of the people. Moreover, the study suggested questioning some other factors causing poverty.
Network Structure of Comorbidity Patterns in U.S. Adults with Depression: A National Study Based on Data from the Behavioral Risk Factor Surveillance System

Background People with depression are at increased risk for comorbidities; however, the clustering of comorbidity patterns in these patients is still unclear. Objective The aim of the study was to identify latent comorbidity patterns and explore the comorbidity network structure that included 12 chronic conditions in adults diagnosed with depressive disorder. Methods A cross-sectional study was conducted based on secondary data from the 2017 behavioral risk factor surveillance system (BRFSS) covering all 50 American states. A sample of 89,209 U.S. participants, 29,079 men and 60,063 women aged 18 years or older, was considered using exploratory graphical analysis (EGA), a statistical graphical model that includes algorithms for grouping and factoring variables in a multivariate system of network relationships. Results The EGA findings show that the network presents 3 latent comorbidity patterns, i.e., that comorbidities are grouped into 3 factors. The first group was composed of 7 comorbidities (obesity, cancer, high blood pressure, high blood cholesterol, arthritis, kidney disease, and diabetes). The second pattern of latent comorbidity included the diagnosis of asthma and respiratory diseases. The last factor grouped 3 conditions (heart attack, coronary heart disease, and stroke). Hypertension reported higher measures of network centrality. Conclusion Associations between chronic conditions were reported; furthermore, they were grouped into 3 latent dimensions of comorbidity and reported network factor loadings. The implementation of care and treatment guidelines and protocols for patients with depressive symptomatology and multimorbidity is suggested.
