Published: September 2024

Abstract

Background
Perinatal Palliative Care (PPC) is individualized medical-nursing care aimed at improving the quality of life of newborns with life-limiting conditions and to support their families. This study draws on the analysis of the experience gained over ten years by a service of PPC called the “Percorso Giacomo” (PG).

Methods
We employed a SWOT analysis to identify the strengths, weaknesses, opportunities, and threats of the PG through a systematic retrospective review of 48 cases followed by the program over the course of 10 years, 21 unsolicited parents’ narrative and 27 experts’ point of view.

Results
Main strengths of the program were communication and parents’ involvement in shared decision-making. Main weaknesses included lack of knowledge of the presence and the role of the PG and lack of resources. For opportunities, the PG proved to be an innovative choice for pregnancies with a fetal life-limiting diagnosis, however threats were identified such as lack of knowledge of PPC and delayed referrals.

Conclusion
The analysis by SWOT method of the 10-year experience of the PG allowed the identification of limitations and areas of improvement, however demonstrated that the PG provided beneficial services to women faced with fetal life-limiting diagnoses.

Impact

Perinatal Palliative Care (PPC) practice and literature on this subject is still limited.

This study offers features of the 10-year experience of the Percorso Giacomo (PG), a service of PPC, through a SWOT analysis.

By identifying strengths, weaknesses, opportunities and threats of the PG, the study shows limitations and areas of improvement but also benefits of a PPC service to women with fetal diagnosis of life-limiting condition and may allow replication in other institutions.

Published: September 2024

Abstract
Background
The close relationship between bile acid (BA) metabolism and sepsis has been investigated in recent years, as knowledge of the role of the gut microbiome and metabolomics in sepsis has grown and become more comprehensive.

Methods
Patients with sepsis who were admitted to the PICU of the Children’s Hospital, Zhejiang University School of Medicine from January 2016 to December 2021 were enrolled in this study. Preoperative non-infectious pediatric patients undergoing elective surgeries in our hospital’s department of surgery were recruited as controls during the same period. Clinical data were collected and analyzed.

Results
702 children were enrolled, comprising 538 sepsis survivors, 164 sepsis fatalities, and 269 non-infected controls. Statistical analysis revealed that total BA (TBA) increased in both the early and severe stages of pediatric sepsis. In the severe stage, TBA (OR = 2.898, 95% CI 1.946–4.315, p < 0.05) was identified as a risk factor for sepsis. A clinical model identified TBA (the cut-off value is >17.95 µmol/L) as an independent predictor of sepsis mortality with an AUC of 0.842 (95% CI 0.800–0.883), sensitivity of 54.9%, specificity of 96.6%, and HR = 7.658 (95% CI 5.575–10.520).

Conclusions
The study showed that elevated TBA was associated with a heightened risk of mortality in pediatric sepsis.

Impact

Many clinical indicators show differences between children with sepsis and the control group, among which the difference in serum total bile acid levels is the most significant.

During the hospitalization of the patients, the overall bile acid levels in the sepsis death group were higher and exhibited greater fluctuations compared to the survival group, with significant differences.

Serum total bile acid levels can serve as effective biomarker for predicting the prognosis of children with sepsis.

AbstractThe worldwide exploration of the ethanolysis protocol (EP) has decreased despite the multifaceted benefits of ethanol, such as lower toxicity, higher oxygen content, higher renewability, and fewer emission tail compared to methanol, and the enhanced fuel properties with improved engine characteristics of multiple-oily feedstocks (MOFs) compared to single-oily feedstocks. The study first proposed a strategy for the optimisation of ethylic biodiesel synthesis from MOFs: neem, animal fat, and jatropha oil (NFJO) on a batch reactor. The project's goals were to ensure environmental benignity and encourage the use of totally biobased products. This was made possible by the introduction of novel population based algorithms such as Driving Training-Based Optimization (DTBO) and Election-Based Optimization (EBOA), which were compared with the widely used Grey Wolf Optimizer (GWO) combined with Response Surface Methodology (RSM). The yield of NFJO ethyl ester (NFJOEE) was predicted using the RSM technique, and the ideal transesterification conditions were determined using the DTBO, EBOA, and GWO algorithms. Reaction time showed a strong linear relationship with ethylic biodiesel yield, while ethanol-to-NFJO molar ratio, catalyst dosage, and reaction temperature showed nonlinear effects. Reaction time was the most significant contributor to NFJOEE yield.The important fundamental characteristics of the fuel categories were investigated using the ASTM test procedures. The maximum NFJOEE yield (86.3%) was obtained at an ethanol/NFJO molar ratio of 5.99, KOH content of 0.915 wt.%, ethylic duration of 67.43 min, and reaction temperature of 61.55 °C. EBOA outperforms DTBO and GWO regarding iteration and computation time, converging towards a global fitness value equal to 7 for 4 s, 20 for 5 s and 985 for 34 s. The key fuel properties conformed to the standards outlined by ASTMD6751 and EN 14,214 specifications. The NFJOEE fuel processing cost is 0.9328 USD, and is comparatively lesser than that of conventional diesel. The new postulated population based algorithm models can be a prospective approach for enhancing biodiesel production from numerous MOFs and ensuring a balanced ecosystem and fulfilling enviromental benignity when adopted.
Opposing neural processing modes alternate rhythmically during sustained auditory attention
Authors: Kasten Florian H. , Busson Quentin , Zoefel Benedikt 
Published: September 2024

AbstractDuring continuous tasks, humans show spontaneous fluctuations in performance, putatively caused by varying attentional resources allocated to process external information. If neural resources are used to process other, presumably “internal” information, sensory input can be missed and explain an apparent dichotomy of “internal” versus “external” attention. In the current study, we extract presumed neural signatures of these attentional modes in human electroencephalography (EEG): neural entrainment and α-oscillations (~10-Hz), linked to the processing and suppression of sensory information, respectively. We test whether they exhibit structured fluctuations over time, while listeners attend to an ecologically relevant stimulus, like speech, and complete a task that requires full and continuous attention. Results show an antagonistic relation between neural entrainment to speech and spontaneous α-oscillations in two distinct brain networks—one specialized in the processing of external information, the other reminiscent of the dorsal attention network. These opposing neural modes undergo slow, periodic fluctuations around ~0.07 Hz and are related to the detection of auditory targets. Our study might have tapped into a general attentional mechanism that is conserved across species and has important implications for situations in which sustained attention to sensory information is critical.

Published: September 2024

AbstractMetal-organic frameworks (MOFs) have emerged as highly promising materials for hosting functional biomolecules. Here, a 1,2,4-benzenetricarboxylate ligand with a flat asymmetric shape is applied to infuse an unusual behavior to a 3D europium MOF (SLU-1). Solvent addition results in the 3D MOF splitting into a 2D one (SLU-2), and in the presence of excess water, gets cross-linked into a different 3D MOF (SLU-3) prone to spontaneous exfoliation. SLU-3 features a combination of highly hydrophilic and hydrophobic spots and serves as an attractive host for incorporating large active species. As a representative demonstration, horseradish peroxidase (HRP) is incorporated into the exfoliated 3D-layered structure by simple mixing, and secured by an outer silica layer in the form of core-shell structures. The resulting HRP-based biocatalyst exhibited enhanced stability and reusability, effectively degrading phenol. This work showcases the potential of reconfigurable MOFs, offering upheld applications through the controlled uptake and retention of biocatalytic agents.

Kinematic control in a four‐wheeled Mecanum mobile robot for trajectory tracking
Authors: Hernández José Carlos Ortiz , Almeida David I. Rosas 
Published: September 2024

AbstractThe challenges of the modern world require mobile robots with the ability to navigate in congested environments with high levels of manoeuvrability. Therefore, the Mecanum wheel may be viable for addressing this challenge. This paper presents the experimental results of a kinematic control strategy, which involves considering the dynamic model as a black box, with only the input and output signals being known. To do this, high‐level and low‐level controllers are formulated and explained. The high level aims to control the desired position of the mobile robot, which can be useful for navigation tasks. On the other hand, low‐level control involves nested controllers to regulate the speed of the mobile robot wheels. Both levels are related and computed through pure kinematics transformations with a dSPACE ds1103 card and MATLAB/Simulink software. In total, 120 experiments were conducted to determine the repeatability of the tests, using the combination of three widely explored control techniques in the literature: proportional‐integral‐derivative (PID), PID plus sliding modes, and PID plus quasi‐sliding modes. The experiments conducted are described in detail, and the results are analysed using statistical indices based on the RMS error and percentage improvement.

Abstract
Background and study aims The Varix Trainer model 1 (VTM1) was
created for trainees to safely practice basic endoscope manipulation skills. The VTM1 was
tested to see if it could distinguish levels of endoscope manipulation skills (construct
validity) and whether training with it could improve these skills faster (content
validity).
Patients and methods We enrolled 23 novice endoscopists, 18
second-year trainees, and 13 expert endoscopists. They were asked to point with the endoscope
tip to 20 numbers in the model as quickly as possible using torque, single-hand small/large
wheel manipulation (SHSW), and retroflexion techniques. Their mean times (t20) were compared
to determine if the model could distinguish different levels of expertise. Subsequently, 14
novices trained for eight short sessions, and the pre-training and post-training t20 were
compared. Nine novice endoscopists received no training and were retested after 4 to 6 weeks
(controls).
Results Experts had faster t20 than second-year trainees, who
were faster than novices, for all three techniques (P < 0.001).
After eight sessions, the mean t20 for novices improved from 112 to 66 seconds for torque, 144
to 72 seconds for SHSW, and 108 to 63 seconds for retroflexion, (all P < 0.001). Their t20 were equivalent to second-year trainees. Improvement in t20
was also seen with the control group, but total reduction was less than for the training
group.
Conclusions The VTM1 distinguished varying levels of expertise
for all techniques, suggesting that it is a valid tool for assessing endoscope manipulation
skill. A short curriculum improved novices’ manipulation skills faster than traditional
practice.

AbstractClinical history is of extreme importance in epilepsy to plan out the management of the patient. Semiology of epilepsy especially at the onset helps us localize the site of onset of the seizure. Ear-plugging semiology in epilepsy, although reported in the literature, is still a rare phenomenon. We hereby report a video of a patient having an ear-plugging epilepsy semiology for better understanding.
Addressing the L2 learning needs of adults with limited education
Authors: Beaulieu Suzie , Fortier Véronique 
Published: September 2024

Abstract
Despite the growing number of second language adult learners with limited education, few classroom-based studies
have investigated how teaching can be better adapted to the characteristics of this population, many of whom have emerging literacy
skills (Penning de Vries et al., 2020). This study aims to fill this gap by
implementing input-based tasks in an intact French L2 language and literacy classroom (N = 13). The input-based
tasks, targeting household items and number marking, were variations of ‘listen-and-do’ tasks that minimize reliance on print or
school-based strategies to achieve task outcomes (Shintani, 2012). To assess whether
the tasks provided opportunities for form-meaning connections, we examined learners’ self- and other-directed speech during task
performance. Results showed multiple opportunities for form-meaning connections suggesting that input-based instruction could be a
useful technique for this context.
Validating the application of the revised ICRP’s biokinetic models for organic 14C and organically bound tritium to members of the public
Authors: Masuda Tsuyoshi , Manabe Kentaro 
Published: September 2024

Abstract
In 2016, the International Commission on Radiological Protection (ICRP) has revised the biokinetic models for carbon and tritium in Publication 134 to calculate the dose coefficients of these radionuclides for workers. The following publication for members of the public is now in the process of revising by the ICRP. According to the draft manuscript published for consultation in 2023, the same models will be adopted for members of the public, although the parameters in these models are not corroborated by the metabolic data of radionuclides in foods. Dose coefficients for adult were estimated using modified models developed in this study to validate the application of the revised ICRP models to members of the public. In the modified models, several parameters were replaced based on the metabolic data of these nuclides in foods and compartments of radio-insensitive tissues were introduced. For these estimations, we utilised an inhouse program for internal-dose calculation developed by the Japan Atomic Energy Agency. The estimated dose coefficient values for ingestion of organic 14C and organically bound tritium (OBT) ranged from 3.2 × 10−11–7.6 × 10−11 Sv Bq−1 and from 3.5 × 10−11–5.4 × 10−11 Sv Bq−1, respectively. We concluded that the dose coefficient value of 1.6 × 10−10 Sv Bq−1 obtained by the revised ICRP’s carbon model was conservative for members of the public, while the value of 5.1 × 10−11 Sv Bq−1 for OBT was appropriate.

Published: September 2024

Abstract
Occupational radiation exposure to the eye lens of medical staff during endoscopic retrograde cholangiopancreatography (ERCP) should be kept low so as not to exceed annual dose limits. Dose should be low to avoid tissue reactions and minimizing stochastic effects. It is known that the head and neck of the staff are exposed to more scattered radiation in an over-couch tube system than in a C-arm system (under-couch tube). However, this is only true when radiation-shielding curtains are not used. This study aimed to compare the protection radiation to the occupationally exposed worker between a lead curtain mounted on a C-arm system and an ERCP-specific lead curtain mounted on an over-couch tube system. A phantom study simulating a typical setting for ERCP procedures was conducted, and the scattered radiation dose at four staff positions were measured. It was found that scattered radiation doses were higher in the C-arm with a lead curtain than in the over-couch tube with an ERCP-specific lead curtain at all positions measured in this study. It was concluded that the over-couch tube system with an ERCP-specific lead curtain would reduce the staff eye dose by less than one-third compared to the C-arm system with a lead curtain. For the C-arm system, it is necessary to consider more effective radiation protection measures for the upper body of the staff, such as a ceiling-suspended lead screen or another novel shielding that do not interfere with procedures.

Published: September 2024

Abstract
The electrostatic accelerometer is the key payload of many space missions, such as satellite gravity measurements, space gravitational experiments, with a typical precision requirement from nano-g to femto-g. The measurement error model analysis is an important issue for the electrostatic accelerometer with numerous error sources. The traditional method by theoretical analysis is complicated to evaluate the complete measurement error models quantitatively especially when the machining and assembly errors of the sensor head are considered. Limited by the earth gravity and seismic noise which is much higher than the intrinsic noise, the complete error model of electrostatic accelerometers can also hardly be tested on ground. In this paper, the method by using finite element analysis of the sensor head is studied. The simulation model for an electrostatic accelerometer sensor head is built, and the multi-conductor capacitance matrix data is simulated. The accuracy of the capacitance simulation is evaluated in three ways including the convergence check of the capacitance with the mesh size, the symmetry verification, and the sensitivity comparison with the theoretical model. Finally, the accelerometer measurement model is analyzed based on the simulation data, using the case of rotating installation misalignment of the upper electrode as an example. The measurement model and error items of one horizontal axis and one rotating axis are quantitatively evaluated. The method proposed in this paper provide a new effective approach to the measurement model analysis of the electrostatic accelerometers in complex working scenarios both in orbit and on ground, which could be helpful to enhance the performance and the efficiency of application.

Abstract
As an excellent vibration energy harvesting material, iron–cobalt–vanadium alloy can be applied in seismic vibration monitoring. In this paper, a self-powered stepped composite structure based on iron–cobalt–vanadium alloy for long-term seismic monitoring is proposed, which can convert the mechanical energy generated by low-frequency transient seismic vibration into a voltage signal for self-powered monitoring. On the basis of its mechanical analysis, a mechano-magneto-electric coupling model is established. The relation between the performance of the voltage and the performance of the material is derived, a variety of magnetostrictive composite structures are produced, the properties of the materials used and the voltage performance generated by the structures are compared and analysed, and a simulated earthquakes platform is constructed for experimenting, and the maximum voltage is 620 mV under a transient force of 1 N, which proves that the composite structure of iron–cobalt–vanadium alloy is excellent in terms of voltage output. Finite element simulation is also used to analyse the role of generated magnetic field on the voltage output of the structure under different bias magnet arrangements, and the sensor is further optimised. Simulated seismic experiments were then carried out to analyse the voltage characteristics and energy harvesting capability. Experimentally, it was confirmed that the generated voltage and deflection were linear with R2 = 0.9966, and the fitting results are accurate. The structure produces a voltage of 1280 mV, an output power of 14.13 mW and a maximum power density of 139.55 mW cm−3 under a transient force of 2 N. The sensor has the advantages of simple structure, large output signal, easy fabrication and long-term operation, therefore, this work highlights the feasibility of harvesting energy from seismic vibration for long term monitoring. It can have good prospective applications in the domain of developing self-powered seismic monitoring and transient vibration energy harvesting.
