Authors: Rocha Ana Carolina , Alamo Leonor , Ostojic Nemanja , Chevallier Christine , Tenisch Estelle 
Published: November 2024

AbstractWe present here a user-friendly calculator for the setting of a pediatric split-bolus polytrauma computed tomography (CT) protocol with a mixed arterial and venous phase, aiming to both reduce radiation dose and improve workflow while assuring optimal image quality. All the different parameters are calculated based on patient’s weight with rapid computation of the injected contrast media and saline volumes, injection’s flow rate, injection’s timing, and optimal acquisition time. The designed calculator is built in a widely available Google Sheets file, accessible by a quick response (QR) code. Although polytrauma imaging represents the main goal of the technique, it can be used in a wide variety of contexts, including oncological, infectious, and vascular pathologies.

Ultrasound-guided interventions in elite soccer players
Authors: Allen Gina M. 
Published: November 2024

Abstract
In the world of elite soccer, or football as we call it in the UK, a player who cannot play for any length of time costs the team money and team performance. The time to return to play (RTP) is crucial in any player’s career, and the use of ultrasound-guided ultrasound injections has become important in the management of injury. In this article, I will explain the importance of good practice when performing these procedures and the use of steroids, sodium hyaluronic acid, platelet-rich plasma (PRP), and other therapies in achieving the goal of decreasing the time of RTP for the footballer.

Key points

•Injection therapies are routine practice in maintaining and treating soccer injuries.

•Injection therapies can be safely performed under ultrasound guidance.
Obstructive hydrocephalus of uncommon etiology: case report and neurosurgical management of aqueductal web presenting in adolescence
Authors: Masarwy Aseel , Watterson Christopher , Boyke Andre , Bonda David , Danielpour Moise 
Published: November 2024

Abstract
Introduction
Aqueductal webs are a rare cause of obstructive hydrocephalus. Accurate diagnosis and intervention can prevent neurological complications.

Case presentation
Herein, we describe a case of a child presenting with headaches and vomiting. Magnetic resonance imaging (MRI) revealed obstructive tri-ventricular hydrocephalus caused by an aqueductal web. Endoscopic third ventriculostomy (ETV) was successfully performed to restore cerebrospinal fluid (CSF) flow.

Conclusion
This case underscores the importance of phase-contrast and T2-weighted cinematic magnetic resonance imaging of cerebrospinal fluid flow for diagnosis of aqueductal webs. These modalities provide valuable insights into CSF dynamics and guidance of appropriate neurosurgical intervention.

Published: November 2024

Abstract
Purpose
Surgeons’ adaptability to robotic manipulation remains underexplored. This study evaluated the participants’ first-touch robotic training skills using the hinotori surgical robot system and its simulator (hi-Sim) to assess adaptability.

Methods
We enrolled 11 robotic surgeons (RS), 13 laparoscopic surgeons (LS), and 15 novices (N). After tutorial and training, participants performed pegboard tasks, camera and clutch operations, energizing operations, and suture sponge tasks on hi-Sim. They also completed a suture ligation task using the hinotori surgical robot system on a suture simulator. Median scores and task completion times were compared.

Results
Pegboard task scores were 95.0%, 92.0%, and 91.5% for the RS, LS, and N groups, respectively, with differences between the RS group and LS and N groups. Camera and clutch operation scores were 93.1%, 49.7%, and 89.1%, respectively, showing differences between the RS group and LS and N groups. Energizing operation scores were 90.9%, 85.2%, and 95.0%, respectively, with a significant difference between the LS and N groups. Suture sponge task scores were 90.6%, 43.1%, and 46.2%, respectively, with differences between the RS group and LS and N groups. For the suture ligation task, completion times were 368 s, 666 s, and 1095 s, respectively, indicating differences among groups. Suture scores were 12, 10, and 7 points, respectively, with differences between the RS and N groups.

Conclusion
First-touch simulator-based robotic skills were partially influenced by prior robotic surgical experience, while suturing skills were affected by overall surgical experience. Thus, robotic training programs should be tailored to individual adaptability.
The first record the Limnia unguicornis (Diptera, Sciomyzidae) parasites on a vulnerable pulmonate land snail, Vertigo moulinsiana (Gastropoda: Eupulmonata: Vertiginidae) and a literature review on Limnia species
Authors: Wendzonka Jacek , Sobczyńska Urszula , Książkiewicz Zofia 
Published: November 2024

AbstractThe literature about mollusc-parasite interactions is focused on species affecting human health, such as trematodes on freshwater snails as intermediate hosts. Far less attention has been paid to parasite-snail interactions in terrestrial habitats. Here we present the first observation of a sciomyzid larva of Limnia unguicornis, parasitizing a vulnerable, tiny air-breading snail, Vertigo moulinsiana (strictly protected by Polish law). Sciomyzids are almost exclusively malacophagous but their biology and ecology are understudied. Thus, we have reviewed the available information on Limnia species and discussed the results of our research.
Unravelling eruption dynamics at El Reventador, Ecuador: linking the physiochemical properties of volcanic ash with geophysical, geochemical and satellite remote sensing data

Published: November 2024

AbstractThe physiochemical properties of volcanic ash are determined by magma ascent and eruption dynamics and provide important insights into controls on the timing and style of volcanic eruptions. However, linking petrological observations to monitoring parameters remains challenging. Here we investigate the relationships between geophysical, geochemical and satellite remote sensing data with the physiochemical properties of volcanic ash to better understand eruptive dynamics at El Reventador volcano, Ecuador. Between 2016 and 2019, eruptive activity at El Reventador was characterised by frequent explosions interspersed with effusive activity from two summit vents. We found that: (1) periods of predominantly effusive behaviour were defined by ash samples with the lowest proportions of juvenile grains, frequent, more intense thermal anomalies and frequent (ca. every 25 min) but low-energy explosions that produced lower average ash column heights (< 1200 m above the summit) and; (2) periods of predominantly explosive behaviour were defined by ash samples with the highest proportions of juvenile grains and also vesicular juvenile grains, low thermal anomalies and less frequent (ca. every 70 min), higher-energy explosions that produced higher average eruption column heights (> 1500 m above the summit). Our study shows that there are strong correlations between the physiochemical properties of erupted material and the multiparametric monitoring data which in turn link to the type of surface activity observed. As a result, the development of physical conduit models and interpretations of eruptive dynamics are made more robust combining both monitoring data and the physical properties of eruptive products.
How does thoracic scoliosis surgery affect thoracolumbar spinal flexibility and lumbar intradiscal pressure? An in vitro study confirming the importance of the rib cage
Authors: Liebsch Christian , Obid Peter , Vogt Morten , Schlager Benedikt , Wilke Hans-Joachim 
Published: November 2024

Abstract

Purpose
To evaluate effects of spinal and rib osteotomies on the resulting spinal flexibility for surgical correction of thoracic scoliosis and to explore effects of posterior fixation on thoracolumbar segmental range of motion and lumbar intervertebral disc loading.

Methods
Six fresh frozen human thoracolumbar spine and rib cage specimens (26–45 years, two female / four male) without clinically relevant deformity were loaded with pure moments of 5 Nm in flexion/extension, lateral bending, and axial rotation. Optical motion tracking of all segmental levels (C7-S) and intradiscal pressure measurements of the lumbar spine (L1-L5) were performed (1) in intact condition, (2) after Schwab grade 1, (3) Schwab grade 2, and (4) left rib osteotomies at T6-T10 levels, as well as (5) after posterior spinal fixation with pedicle screw-rod instrumentation at T4-L1 levels.

Results
Schwab grade 1 and 2 osteotomies did not significantly (p > 0.05) affect spinal flexibility, whereas left rib osteotomies significantly (p < 0.05) increased segmental ranges of motion at upper and lower levels in flexion/extension and at treated levels in lateral bending. Posterior fixation caused significantly (p < 0.05) increased range of motion at upper adjacent thoracic and mid-lumbar levels, as well as significantly (p < 0.05) increased intradiscal pressure at the lower adjacent level.

Conclusion
Low effects of Schwab grade 1 and 2 osteotomies question the impact of isolated posterior spinal releases for surgical correction maneuvers in adolescent idiopathic scoliosis, in contrast to additional concave rib osteotomies. High effects of posterior fixation potentially explain frequently reported complications such as adjacent segment disease or proximal junctional kyphosis.
On Cournot and Bertrand competition in collusive mixed oligopolies
Authors: Escrihuela-Villar Marc , Guillén Jorge 
Published: November 2024

AbstractWe consider a mixed oligopoly of one public and N private firms where goods are horizontally differentiated. In our setting, an interdependent payoff structure characterizes the degree of collusion among private firms. We show that, whereas in the Bertrand model, private firms are willing to collude as much as possible, in the Cournot model, the existence of a public firm reduces the scope of collusion. We also prove that the classic discussion comparing price and quantity competition crucially depends on market collusion. More precisely, price competition unambiguously yields larger profits for private firms only if collusion is high enough. In an infinitely repeated game, we prove that collusion is easier to sustain in a larger oligopoly because, in this case, a larger N helps mitigate the effect of the public firm on private firms’ collusion sustainability. Finally, we also find that collusion is always more easily sustained in the Bertrand case than in the Cournot case.

Published: November 2024

Abstract
Aim
An increase in average temperatures and acute heat events has been observed, which has led to an increase in hospital treatments. In the course of climate change, this may lead to a temporary overload of the healthcare system in the future. The aim of this review was to find out how digital health planning tools can be used to optimize the distribution of available resources and counteract overloads. In addition, the review sought to gather comprehensive insights to develop a corresponding tool as part of the project Medical Informatics Hub in Saxony (MiHUBx).

Subjects and methods
Six scientists from different disciplines were involved in the study, which was carried out as part of MiHUBx. The inclusion and exclusion criteria, based on the PICOS-scheme, guided the selection of relevant studies. The search was conducted in the Medline, IEEE and Web of Science databases and limited to the last ten years.

Results
We identified 21 studies published between 2013 and 2022. A connection was found between heat and use of the health system. These studies presented a conceptual framework, but none described the implementation of the instruments in standard care. However, it was shown that statistic models based on weather and health data can be suitable for predicting resource utilization and can optimize health supply.

Conclusion
It was shown that statistic models are suitable for predicting the use of resources to optimize healthcare provision and can therefore be developed in the project. In addition, requirements for the development of a resource allocation and planning tool were identified.
Equilibrium loadings and adsorption isotherm model parameters estimated from multi-component breakthrough curves
Authors: Zarei Somayeh , Harriehausen Isabel , Lee Ju Weon , Seidel-Morgenstern Andreas 
Published: November 2024

AbstractQuantitative knowledge of competitive adsorption isotherms is essential for the design and optimization of adsorption based separation processes. Since the experimental determination of these thermodynamic functions is complicated and time consuming, there is a need for fast and easy to apply methods. In particular attractive are methods that evaluate measured breakthrough curves (BTC). Key features of these curves can be predicted with the equilibrium theory, which ignores kinetic effects that cause band broadening. If the adsorption equilibria can be described by the classical competitive Langmuir isotherm model, outlet concentration profiles can be calculated analytically. The paper summarizes and illustrates well-known classical results for N-component systems. The theory is applied to analyze experimentally determined BTC for a ternary mixture fed into an initially fully regenerated column under constant flowrate and under isothermal conditions. It is demonstrated that the retention times and intermediate plateau concentrations, which are observable for example in a single ternary BTC experiment, allow estimating a defined number of characteristic equilibrium loadings. These loadings can be directly used for easy estimation of the parameters of an assumed isotherm model. Various possibilities to use a reduced number of loadings and to include complementary results of standard pulse experiments are described. The isotherms generated from the ternary BTC are successfully validated by results of single component and ternary BTC experiments carried out subsequently. Options to generalize the method to determine isotherm model parameters from measured BTC to initially preloaded columns and to more complex mixtures are finally outlined.
Impact of climate change on the pollen season on relevant species in Iberian’s dehesa: a case study of Fraxinus sp.
Authors: Galindo Ortiz Sheila , García Sánchez Asunción , Sánchez Reyes Estefanía 
Published: November 2024

AbstractThe allergenic nature of ash (Fraxinus sp.), an important element of the dehesas, has been poorly studied in meridional Europe owing to the low concentrations of this pollen type in the atmosphere. However, it has cross-reactivity with Olea L. and other homologous allergens of trees and herbaceous species, leading to earlier and more prolonged respiratory allergenic symptoms. The main aims of this work were to characterize the main pollen season (MPS) of ash from 2011 to 2022, to evaluate the influence of meteorological variables on airborne concentrations of this pollen type and to elaborate a pollen calendar for Fraxinus in Salamanca. The aeropalynological analysis for the eleven years of the study shows that the MPS for Fraxinus begins on 27 th December until 4 th April with an average duration of 100 days, a mean peak value of 57 grains/m3 reached on 22 nd February and a mean annual pollen integral of 567 grains/m3, observing an earlier onset of MPS, an increase in its duration and a decrease in its concentrations, presumably linked to climate change. Regarding the influence of meteorological parameters on pollen concentrations, positive correlations were found for maximum and mean temperatures and insolation, as well as southeast winds and frequency of calms, while negative correlations were reported for precipitation, relative humidity, and wind speed. The analyze of Fraxinus pollen could be used to predict seasonal behavior and warn people who may suffer pollinosis either from ash pollen or from cross-reactivity events.
Epistemic selection of costly alternatives: the case of participatory budgeting
Authors: Rey Simon , Endriss Ulle 
Published: November 2024

AbstractWe initiate the study of voting rules for participatory budgeting using the so-called epistemic approach, where one interprets votes as noisy reflections of some ground truth regarding the objectively best set of projects to fund. Using this approach, we first show that both the most studied rules in the literature and the most widely used rule in practice cannot be justified on epistemic grounds: they cannot be interpreted as maximum likelihood estimators, whatever assumptions we make about the accuracy of voters. Focusing then on welfare-maximising rules, we obtain both positive and negative results regarding epistemic guarantees.

Published: November 2024

Abstract
Young adulthood is a critical development period when mental health problems such as anxiety and depression become more prevalent. Likewise, there is evidence to suggest that depression and anxiety may lead to increased pornography usage. We examined the association of depression and anxiety symptoms with pornography viewing frequency among a prospective cohort of young adults (n = 1864) from California. Multinomial logistic regression models estimated the association of depression symptoms only, anxiety symptoms only, and comorbid depression and anxiety with pornography viewing frequency (never, < 3 times/month, one to several times/week, one to several times/day) at a 6-month follow-up. Models adjusted for gender, sexual orientation, sexual satisfaction, and adverse childhood experiences. Participants with comorbid depression and anxiety (vs. no depression or anxiety symptoms) had 2.72 (95% CI: 1.66–4.46) times the odds of frequent pornography viewing (one to several times/day) compared to never watching pornography. There was an association of depression symptoms only with frequent pornography viewing but it did not reach statistical significance (OR: 1.95, 95% CI: 0.78–4.89). Anxiety symptoms alone (vs. no depression and anxiety symptoms) were not associated with pornography viewing at any frequency in the full sample. However, in gender-stratified models, anxiety symptoms alone were associated with pornography viewing among women (OR: 1.44. 95% CI: 1.00–2.07), but not men (1.12, 95% CI: 0.65–1.96). Findings suggest comorbid depression and anxiety symptoms are associated with frequent pornography viewing among young adults, and anxiety symptoms alone are associated with pornography viewing among women, but not men.
Seismic vulnerability of a pre-code, reinforced concrete, apartment-block building

Published: November 2024

AbstractThis research studies the Damage State Probability of a pre-code reinforced concrete apartment block building designed for gravity loads only. The study refers to the moderate damage state associated with apparent cracking and the onset of concrete spalling that exposes the transverse reinforcement. This damage state is chosen for the analysis because it is highly correlated with the number of displaced households in the case of a damaging earthquake. We analyze the structural inelastic earthquake response using 50 ground acceleration records to create the fragility curve function for four ground motion intensity measures. From the four intensity measures used in this study, the peak-ground velocity is found to be most highly correlated to the damage state probability of the analyzed structure. Because this structural type is very common throughout Israel, including in towns close to the active Dead Sea fault, near-fault effects are considered in the analysis but are found to be relatively insignificant due to the dynamic properties of the analyzed building. Finally, a potential retrofit solution is proposed, incorporating financial and serviceability limitations. The proposed retrofit effectiveness is made clear by comparing the fragility curves with and without the suggested retrofit. For example, the horizontal peak acceleration required for a 50% probability of achieving the damage state is increased from 0.18 g to 0.32 g for the original and retrofitted building, respectively. The analysis also shows that the generic curves currently in the Hazus platform, which is widely used for national risk analysis in Israel, overestimate the earthquake resilience of the addressed building and should, therefore, be updated and replaced with more accurately obtained curves.
