Published: March 2024

To evaluate the effects of Picochlorum on shrimp culture, Picochlorum was added to the culture system of Litopenaeus vannamei at concentrations of 1×104cells/mL(KH_1), 2×104cells/mL(KH_2) and 4×104cells/mL(KH_4), and three culture systems with no Picochlorum addition were set up as control group(KH_D) . The water quality, diversity of microalgae community, growth performance and immune-related enzyme activities of shrimp were monitored in each treatment group.
The results showed that, all three treatment groups with Picochlorum addition were effective in removing total ammonia nitrogen (TAN), nitrite, phosphate,and chemical oxygen demand (COD) from culture water compared to the control group. KH_4 had the best water purification effect among the three treatment groups. At the end of the experiment, TAN, nitrite, phosphate and COD contents of KH_4 were 0.75 mg/L, 1.41 mg/L, 0.76 mg/L, and 8.2 mg/L, respectively, which decreased by 89.85%, 78.17%, 50.00%, and 63.28%, respectively, compared to KH_D.
High-throughput sequencing analysis showed that the absolute dominant genus in the microalgae communities of KH_1, KH_2 and KH_4 were all Picochlorum, with relative abundances of 70.03%, 71.69% and 95.65% respectively, and were significantly higher than that in KH_D (p<0.05). The absolute dominant microalgae in KH_D was Isochrysis (69.59%). The addition of Picochlorum had a significant impact on the microalgae community diversity structure in the shrimp farming system.
The superoxide dismutase (SOD) activities of shrimp in KH_D,KH_1,KH_2 and KH_4 groups were 88.50 U/mg prot,116.58 U/mg prot,157.57 U/mg prot,152.23 U/mg prot,and the lysozyme (LZM) activities were 29.48 U/mg prot,34.47 U/mg prot,47.17 U/mg prot, 51.22 U/mg prot.The activities of both enzymes were increased by 31.73%-78.05% and 16.93%-73.74% in the experimental group of Litopenaeus vannamei (KH_1, KH_2, KH_4) compared to KH_D, respectively. The enzyme activities and growth performance of Litopenaeus vannamei in KH_2 and KH_4 were significantly better than that in KH_D (P < 0.05).
In summary, the addition of Picochlorum can improve the shrimp culture water environment and promote shrimp growth, which is a feasible solution for shrimp aquaculture environmental control.

Background
Nasal allergen provocation tests are an important part of the diagnostics of allergic diseases triggered by environmental factors. Recently, increased attention has been paid to the potential use of this method in the diagnosis of food allergy. The objective of the study was to evaluate the usefulness of the nasal allergen provocation test in a group of subjects allergic to hen`s egg white allergens.
Methods
The material consisted of a group of 57 subjects (32 subjects with hen`s egg white allergy and 25 healthy controls). The method consisted in a nasal allergen provocation test carried out with the use of hen`s egg white allergen and assessed using the visual analog scale and optical rhinometry as well as by determination of sIgE and tryptase levels in nasal lavage fluid.
Results
Subjective nasal symptoms and objective evaluations following the application of 100 µg of hen`s egg white allergen revealed a moderately positive nasal mucosal response in optical rhinometry tests (ΔE = 0.34 OD).
Conclusions
Nasal food challenge with hen`s egg white allergen is a good diagnostic alternative in the group of food allergy patients. Due to the insufficient number of studies carried out so far, further attempts at standardization of the method are required.
SGK1 contributes to endothelial cell ferroptosis in coronary heart disease through the NEDD4L/NF-κB pathway
Authors: Peng Yong , Jiang Yu , Zhou Qingfeng , Jia Zheng , Tang Han
Published: March 2024

The prevalence of coronary heart disease (CHD) has increased significantly with the aging population worldwide. It is unclear whether ferroptosis occurs during CHD. Hence, we aimed to investigate the potential mechanisms associated with ferroptosis in CHD. Bioinformatics was used to characterize differentially expressed genes (DEGs) in CHD-related datasets (GSE21610 and GSE66360), and enrichment analysis was performed via protein‒protein interaction (PPI) network analysis. Proteins that interact with SGK1 as predicted by the String database. Flow cytometry and western blot analysis revealed alterations in lipid peroxidation, Fe accumulation, and ferroptosis-related marker expression in MAECs following lentivirus-mediated modulation of SGK1 and NEDD4L expression. A total of 76 and 689 DEGs were involved in pathways associated with immune and inflammatory responses, respectively. DDX3Y, EIF1AY, KDM5D, RPS4Y1, SGK1, USP9Y, and NSG1 showed intersecting DEGs. The differences in the number of circulating endothelial cells (ECs) between healthy individuals and CHD patients are consistent with the results of bioinformatics analysis. SGK1 may interact with NEDD4L and promote NEDD4L and p-P65 expression in MAECs according to the String database. Additionally, SGK1 knockdown alleviated the Erastin-induced downregulation of SLC7A11, GPX4, GSH, and GSSG, as well as the upregulation of lipid peroxidation, Fe accumulation, p-P65 expression, and mitochondrial damage. NEDD4L and PMA (NF-κB pathway activator) were rescued with overexpression. SGK1 contributes to EC ferroptosis by regulating the NEDD4L-NF-κB pathway. SGK1 could be recognized as a therapeutic target related to ferroptosis in CHD.
The Effect of Distance on Audiovisual Temporal Integration in an Outdoor Virtual Environment
Authors: Fucci Victoria , Krol Pelle , Plaisier Myrthe , Cuijpers Raymond H.
Published: March 2024

In this study, we explore the influence of stimulus distance on human tolerance for (physical) asynchronies in virtual reality (VR). A repeated audiovisual (AV) stimulus with sound and light bursts was presented to the participants in an outdoor virtual environment (VE) using a head-mounted display (HMD). The investigation focused on quantifying the point of subjective simultaneity (PSS) for both visual and auditory stimuli. A synchrony judgment method (SJ-3) was used for 11 stimulus onset asynchronies (SOA) and five egocentric distances from 10 m up to 50 m with 10 m increments. The data analysis showed negative PSS values that decreased with distance, resulting in a negative slope (-3 ms/m) of the regression line between PSS values and simulated distances. In contrast to our previous study in the indoor VE \citep{vfucci}, we conclude that the presented study in the outdoor VE does not incorporate a distance compensation mechanism and refutes the hypothesis of an "implicit estimation" of sound-arrival time. The reasons behind the observed contrast are discussed in this paper. Moreover, the negative slope of the regression line (-3 ms/m) is similar to the previous research by \citet{lewald_guski_2004}, who concluded that there is simply a temporal integration of auditory-visual information within human neural processes without distance compensation.

Published: March 2024

The paper summarises the results of a three-year research study (Russian Science Foundation grant: 22-17-00035) aimed at investigating the variability of chemical composition and the species diversity and functional structure of planktonic communities in saline lakes of Transbaikalia (Russia). According to the ionic content, the lakes were classified either as soda (13 lakes), chloride (3 ones), and sulphate (2 ones) types. Water salinity ranges widely, from 0.5 to 334.5 g/L in soda lakes, from 8.2 to 257.8 g/L in chloride ones, and from 21.3 to 146.8 g/L in sulphate ones. In all lakes the cation Na+ dominated, with its concentration increasing as the salinity of the water rises. An increase in salinity, accompanied by a sequential change in the chemical types and subtypes of lakes, led to an excess of bioavailable forms of nitrogen and phosphorus. Diversity and density of phytoplankton and zooplankton depent both to an increase in the total salt content and to the anionic composition of water. Salinity constrains species composition and functional diversity and leads to changes in trophic structure and density of some aquatic organisms. We determined two assemblages of aquatic organisms: Anabaenopsis knipowitschii and Brachionus angularis prefering sulphate dominated habitats and Limnospira fusiformis, Ascomorpha ecaudis, and Hexarthra mira commonly associating with carbonate dominated habitats.

Authors: Farid Samina , Nazir Shaista
Published: March 2024

Natural polysaccharides own properties like biocompatibility, biodegradability, nontoxic and inexpensive material, gaining attention for biomedical applications. Mangifera indica gum is an excellent source of polysaccharides. The present research is aimed to investigate the impact of modification on polysaccharides extracted from Mangifera indica gum. Polysaccharide extracted from Mangifera indica gum was subjected to modification through the acrylamide grafting method to enhance the functionality of natural polysaccharide. It was noted that for 100 grams of dried mango gum, 12 grams of modified polysaccharide and 15 grams of crude polysaccharide were produced. Characterization techniques such as FTIR was used to determine the functional groups on the structure of polysaccharide. The surface morphology and crystalline structure were elucidated from SEM, EDX, and XRD. The antioxidant and antibacterial activity of native and modified polysaccharides was studied. The results thus obtained were statistically analyzed and reported. The modification of native polysaccharides was expected to find low antioxidant activity after modification but gum polysaccharides did not show any antibacterial activity against Escherichia coli, Pseudomonas sp., Bacillus sp., and Staphylococcus aureus in both native and modified polysaccharides.

Purpose Immiscible filtration assisted by surface tension (IFAST) is a microfluidic technique that uses the principle of surface tension for the extraction of analytes such as nucleic acids, proteins, and metabolites. This immiscible phase filtration technique was tested via two different cost-effective methods.Methods Two cost-effective methods for applying the IFAST technique were developed and the procedures were compared for effectiveness. These methods involved the use of plastic canvas and Eppendorf tubes for device fabrication and DNA extraction.Results In the first method, several challenges are faced, which are discussed in this research, where plastic canvas is used instead of expensive materials such as polydimethylsiloxane (PDMS). On the other hand, the air-jump method is better for DNA extraction because of the new approach of using Eppendorf tubes for IFAST.Conclusion Applying the IFAST technique using the air-jump method is a relatively more robust, economical and effective method than the use of a plastic canvas device.

An estimate on red mud waste management to diversify the Jamaican economy
Authors: Williams Jullian C.B. , Williams Rudyard
Published: March 2024

Red mud waste is a residual product from the processing of bauxite to extract aluminum. This waste product is an iron rich clay that is also laden with rare earth element (REE) materials. The use of red mud clay is not limited to rare earths but has also been proposed for building material such as bricks and cement mix. Industrial materials undergo a series of stress and strain testing and standard proctor tests to determine the integrity of the building material mix. However, estimating the available volume of material for procurement is necessary for economic pursuits. As the bauxite mining industry in Jamaica produces more red mud waste, the available building material increases. Therefore, it is useful to estimate the total volume of red mud clay for industrial development.
In this study, we use remote sensing techniques to quantify the volume of material in the Windalco residual lake in Manchester, Jamaica. We observe the residual pit using advanced measurements from satellite instruments to improve land surveying and investment protection.
Evaluating the Soil Block Method and Growing Media in Organic Vegetable Transplant Production
Authors: Carey Anne , Nair Ajay , Thoms Adam
Published: March 2024

Organic vegetable growers are interested in using the “soil block” method for transplant production as an alternative to plastic flats. The soil block method compresses growing media into a freestanding block in contrast to the cells of a plastic flat. Anecdotal evidence of soil block–grown transplants with increased vigor and root development exists, but limited research has been conducted to evaluate these claims. Furthermore, identifying commercial growing medium for certified organic transplant production is needed. The objective of this study was to compare growth parameters and root development of cucumber (Cucumis sativus) and pepper (Capsicum annum) transplants grown in soil blocks and plastic flats, in combination with four commercially available certified organic media (Beautiful Land Products “Soil Blocking Mix,” Purple Cow Organics “Seed Starter Mix,” Cowsmo “Green Potting Soil,” and Vermont Compost Company “Fort Vee”). A volume-based 50% peat, 25% compost, 12.5% perlite, and 12.5% vermiculite growing medium was also evaluated. A split-plot randomized complete block design with four replications was used with growing method as the whole plot factor and medium as the subplot factor. ‘Marketmore 76’ cucumbers and ‘Yankee Bell’ peppers were seeded in 50-cell flats and soil blocks made with Johnny’s Selected Seeds Stand-up 12 Soil Blocker. Data were collected on growth parameters by destructively sampling cucumbers 3 weeks after seeding, and peppers 5, 6, and 7 weeks after seeding. Root development was evaluated using WinRHIZOTM at the last sampling. Cucumber and pepper transplants performed differently in soil blocks and flats. Cucumbers grown in flats had a significantly greater dry weight than those grown in soil blocks, by 20% in 2022 and by 38% in 2023. In contrast, pepper transplants grown with the soil block method had between 50% and 130% greater dry weight in the final sampling in 2022. Cucumber and pepper transplants grown with Cowsmo “Green Potting Soil” performed poorly, with an up to 144% lower dry weight and up to 167% lower root surface area than transplants grown with the other media. Root development correlated with shoot development, without a specific advantage in soil blocks, although differences in root system architecture should be investigated. The evaluated Beautiful Land Products, Purple Cow Organics, and Vermont Compost Company media can all be considered suitable for growing certified organic vegetable transplants in both soil blocks and flats. Further research is warranted to better optimize the soil block technique, investigate optimum soil block bulk density, and inform growers of appropriate commercially available certified organic growing media for organic vegetable transplant production.
The partial Bondi gauge: Gauge fixings and asymptotic charges
Authors: Geiller Marc , Zwikel Céline
Published: March 2024

In the companion paper [SciPost Phys. 13, 108 (2022)] we have studied the solution space at null infinity for gravity in the partial Bondi gauge. This partial gauge enables to recover as particular cases and among other choices the Bondi-Sachs and Newman-Unti gauges, and to approach the question of the most general boundary conditions and asymptotic charges in gravity. Here we compute and study the asymptotic charges and their algebra in this partial Bondi gauge, by focusing on the flat case with a varying boundary metric \delta q_{AB}≠0δqAB≠0. In addition to the super-translations, super-rotations, and Weyl transformations, we find two extra asymptotic symmetries associated with non-vanishing charges labelled by free functions in the solution space. These new symmetries arise from a weaker definition of the radial coordinate and switch on traces in the transverse metric. We also exhibit complete gauge fixing conditions in which these extra asymptotic symmetries and charges survive. As a byproduct of this calculation we obtain the charges in Newman-Unti gauge, in which one of these extra asymptotic charges is already non-vanishing. We also apply the formula for the charges in the partial Bondi gauge to the computation of the charges for the Kerr spacetime in Bondi coordinates.
The Floquet Baxterisation
Authors: Miao Yuan , Gritsev Vladimir , Kurlov Denis V.
Published: March 2024

Quantum integrability has proven to be a useful tool to study quantum many-body systems out of equilibrium. In this paper we construct a generic framework for integrable quantum circuits through the procedure of Floquet Baxterisation. The integrability is guaranteed by establishing a connection between Floquet evolution operators and inhomogeneous transfer matrices obtained from the Yang-Baxter relations. This allows us to construct integrable Floquet evolution operators with arbitrary depths and various boundary conditions. Furthermore, we focus on the example related to the staggered 6-vertex model. In the scaling limit we establish a connection of this Floquet protocol with a non-rational conformal field theory. Employing the properties of the underlying affine Temperley-Lieb algebraic structure, we demonstrate the dynamical anti-unitary symmetry breaking in the easy-plane regime. We also give an overview of integrability-related quantum circuits, highlighting future research directions.

Monitoring the water usage of different appliances and informing consumers about it has been shown to have an impact on their behavior toward drinking water conservation. The most practical and cost-effective way to accomplish this is through a non-intrusive approach, that locally analyzes data received from a flow sensor at the main water supply pipe of a household. In this work, we present two different methods addressing the challenges of disaggregating end-use consumption and classifying consumption events. The first method is model-based (MB) and uses a combination of dynamic time wrapping and statistical bounds to analyze four water end-use characteristics. The second, learning-based (LB) method is data-driven and formulates the problem as a time-series classification problem without relying on a priori identification of events. We perform an extensive computational study that includes a comparison between an MB and an LB method, as well as an experimental study to demonstrate the application of the LB method on an edge computing device. Both methods achieve similar F1 scores (LB: 71.73%, MB: 71.04%) with the LB being more precise. The embedded LB method achieves a slightly higher score (72.01%) while enhancing on-site real-time processing, improving security and privacy and enabling cost savings.

Published: March 2024

Background::

Coronary Heart Disease (CHD) is one of the most common types of cardiovascular disease, and Heart Failure (HF) is an important factor in its
progression. We aimed to evaluate the diagnostic value and predictors of multiparametric Cardiac Magnetic Resonance (CMR) in CHD patients
with HF.

Methods::

The study retrospectively included 145 CHD patients who were classified into CHD (HF+) (n = 91) and CHD (HF–) (n = 54) groups according to
whether HF occurred. CMR assessed LV function, myocardial strain and T1 mapping. Multivariate linear regression analyses were performed to
identify predictors of LV dysfunction, myocardial fibrosis, and LV remodeling

Results::

CHD (HF+) group had impaired strain, with increased native T1, ECV, and LVM index. The impaired strain was associated with LVM index (p <
0.05), where native T1 and ECV were affected by log-transformed amino-terminal pro-B-type natriuretic peptide (NT-proBNP) levels. ROC
analysis showed the combination of global circumferential strain (GCS), native T1, and LVM had a higher diagnostic value for the occurrence of
HF in CHD patients.
Meanwhile, log-transformed NT-proBNP was an independent determinant of impaired strain, increased LVM index, native T1 and ECV.

Conclusion::

HF has harmful effects on LV systolic function in patients with CHD. In CHD (HF+) group, LV dysfunction is strongly correlated with the degree
of LV remodeling and myocardial fibrosis. The combination of the three is more valuable in diagnosing HF than conventional indicators.
Design and Development of Hypertuned Deep learning Frameworks for
Detection and Severity Grading of Brain Tumor using Medical Brain MR
images
Authors: Bhardwaj Neha , Sood Meenakshi , Gill Sandeep Singh
Published: March 2024

Background::

Brain tumor is a grave illness causing worldwide fatalities. The current detection methods for brain tumors are manual, invasive, and rely on
histopathological analysis. Determining the type of brain tumor after its detection relies on biopsy measures and involves human subjectivity. The
use of automated CAD techniques for brain tumor detection and classification can overcome these drawbacks.

Objective::

The paper aims to create two deep learning-based CAD frameworks for automatic detection and severity grading of brain tumors – the first model
for brain tumor detection in brain MR images and model 2 for the classification of tumors into three types: Glioma, Meningioma, and Pituitary
based on severity grading.

Methods::

The novelty of the research work includes the architectural design of deep learning frameworks for detection and classification of brain tumor
using brain MR images. The hyperparameter tuning of the proposed models is done to achieve the optimal parameters that result in maximizing the
models' performance and minimizing losses.

Results::

The proposed CNN models outperform the existing state of the art models in terms of accuracy and complexity of the models. The proposed model
developed for detection of brain tumors achieved an accuracy of 98.56% and CNN Model developed for severity grading of brain tumor achieved
an accuracy of 92.36% on BraTs dataset.

Conclusion::

The proposed models have an edge over the existing CNN models in terms of less complexity of the structure and appreciable accuracy with low
training and test errors. The proposed CNN Models can be employed for clinical diagnostic purposes to aid the medical fraternity in validating
their initial screening for brain tumor detection and its multi-classification.

Authors: Farrokhi Vida , Afrisham Reza , Soleimani Masoud , Ahmadvand Mohammad , Mousavi Seyed Hadi , Kashanikhatib Zahra , Owchi Somayeh , Mohammadali Fatemeh , Alizadeh Shaban
Published: March 2024

Introduction:

Functional reduction of telomeres can induce DNA damage response
through cell cycle checkpoints and contribute to the senescence of stem cells. The effect of exosomes
on the aging and rejuvenation of hematopoietic stem cells (HSCs) is not well known. Therefore, the
present study is designed to examine the impact of plasma exosomes derived from young and old
individuals on hTERT and P16 expression involved in the cellular aging process.

Methods:

Exosomes isolated from four young (Y-Exo) and four old (O-Exo) men were evaluated for
CD63 protein expression, morphology, size and zeta potential. HSCs were treated with exosomes,
and then, the cell viability and the mRNA expression (hTERT and P16) were evaluated using MTT
and qRT-PCR methods, respectively. To measure the hTERT protein level, a western blot technique
was performed.

Results:

The gene expression of hTERT was significantly decreased in HSCs treated with 5 μg/ml
(O5-Exo) and 10 μg/ml (O10-Exo) doses of exosomes obtained from elderly individuals compared to
the cells treated with young exosomes and the untreated HSCs (p < 0.05). In addition, there was a
profound elevation of hTERT protein in the HSCs treated with both doses of young exosomes in
comparison with the cells treated with both doses of old exosomes (p < 0.05). Moreover, P16 expression
was markedly upregulated in the O5-Exo and O10-Exo groups compared to the untreated group
(p < 0.05).

Conclusion:

Our findings reinforce the concept that depending on the age of individuals, circulating
exosomes may acquire properties that affect the pathways involved in the aging process in HSCs.

For several decades, the memory of the Holocaust has been a central element of Jewish identity. However, some descendants of survivors have lately criticized the way this commemoration has been carried out, both in a family context (where the father figureoften plays an essential role) and through popular culture, endorsing other formulas involving greater intercultural dialogue. This article analyzes the works of two comic strip authors who are part of this trend, Michel Kichka and Joann Sfar, by examining the alternative concept of identity that they propose.

Camille Claudel’s provocative personality never ceased to attract the attention of her contemporaries: she entered a profession considered masculine, she upset the master’s heart and she became a cursed artist while being the sister of a renowned Catholic writer. Her life is full of drama and legend. This article examines the ways in which the sculptor’s personality is relevant today. The portraits of Claudel provided by Catherine Anne, Michèle Desbordes and Colette Fellous will demonstrate that she is part of the collective memory. It will also be shown that in analysing the life of Camille Claudel, these three authors are revealing their own haunts

Published: March 2024

Many artistic initiatives are currently being developed in Colombia. This country is struggling to reconstruct its own narrative in the face of armed conflict that has been going on since the 1940s. Art provides a space of openness and mediation. It bears witness to the memory of those who went through this conflict and are still suffering its consequences. A Peace Agreement was signed in 2016 between the FARC-EP guerrillas and the government of ex-president Juan Manuel Santos, but the uncertaintyof its implementation affects both the civilian community and the peace signatories. In this context, the encounter around muralism and graffiti unites the urban artists of Medellín and the peace signatories of Chocó. These artistic practices allow them to assert their values and build a peaceful community.

Investigating Nonspecific Effects of the Live-Attenuated Japanese Encephalitis Vaccine on Lower Respiratory Tract Infections in Children Aged 25-35 Months: Retrospective Cohort Study
Authors: Zhan Siyi , Lin Hongbo , Yang Yingying , Chen Tao , Mao Sheng , Fu Chuanxi
Published: March 2024

Background

Live attenuated vaccines may be used to prevent nontargeted diseases such as lower respiratory tract infections (LRTIs) due to their nonspecific effects (NSEs).

Objective

We aimed to analyze the NSEs of the Japanese encephalitis vaccine on pediatric LRTIs in children aged 25 months to 35 months.

Methods

A retrospective cohort study was conducted by using a population-based electronic health record database in Zhejiang, China. Enrolled participants were children born from January 1, 2017, to December 31, 2017, and who were inoculated with the live-attenuated Japanese encephalitis vaccine (JE-L) or inactivated Japanese encephalitis vaccine (JE-I) as the most recent vaccine at 24 months of age. The study was carried out between January 1, 2019, and December 31, 2019. All inpatient and outpatient hospital visits for LRTIs among children aged 25 months to 35 months were recorded. The Andersen-Gill model was used to assess the NSEs of JE-L against LRTIs in children and compared with those of JE-I as the most recent vaccine.

Results

A total of 810 children born in 2017 were enrolled, of whom 585 received JE-L (JE-L cohort) and 225 received JE-I (JE-I cohort) as their last vaccine. The JE-L cohort showed a reduced risk of LRTIs (adjusted hazard ratio [aHR] 0.537, 95% CI 0.416-0.693), including pneumonia (aHR 0.501, 95% CI 0.393-0.638) and acute bronchitis (aHR 0.525, 95% CI 0.396-0.698) at 25 months to 35 months of age. The NSEs provided by JE-L were especially pronounced in female children (aHR 0.305, 95% CI 0.198-0.469) and children without chronic diseases (aHR 0.553, 95% CI 0.420-0.729), without siblings (aHR 0.361, 95% CI 0.255-0.511), with more than 30 inpatient and outpatient hospital visits prior to 24 months of age (aHR 0.163, 95% CI 0.091-0.290), or with 5 to 10 inpatient and outpatient hospital visits due to infectious diseases prior to 24 months old (aHR 0.058, 95% CI 0.017-0.202).

Conclusions

Compared with JE-I, receiving JE-L as the most recent vaccine was associated with lower risk of inpatient and outpatient hospital visits for LRTIs among children aged 25 months to 35 months. The nature of NSEs induced by JE-L should be considered for policymakers and physicians when recommending JE vaccines to those at high risk of infection from the Japanese encephalitis virus.

BACKGROUND

Acquired brain injury (ABI) is a prominent cause of disability globally, with virtual reality (VR) emerging as a promising aid in neurorehabilitation. Nonetheless, the diversity among VR interventions can result in inconsistent outcomes and pose challenges in determining efficacy. Recent reviews offer best practice recommendations for designing and implementing therapeutic VR interventions to evaluate the acceptance of fully immersive VR interventions.

OBJECTIVE

This study aims to evaluate the usability and feasibility of a co-designed VR-based neurorehabilitation support tool by conducting multiple proof-of-concept trials in a sample of patients with ABI within a hospital setting.

METHODS

A single session deploying custom immersive serious games to train cognitive functions using a new-generation head-mounted display was conducted among a sample of inpatients with ABI. Structured questionnaires were administered at the end of the session to evaluate the usability of the system and the intervention, participants’ familiarity with the technology, and any adverse effects related to cybersickness. Additionally, the training duration while wearing the headset and the demographic characteristics of the participants were considered.

RESULTS

A total of 20 patients with ABI participated in a 1-hour proof-of-concept trial. The mean usability score was 37 (SD 2.6) out of 40, the technology familiarity level was 9.2 (SD 2.9) out of 12, and the Simulator Sickness Questionnaire total score was 1.3 (SD 2). On average, participants wore the headset for approximately 25.6 (SD 4.7) minutes during the intervention. There were no substantial differences in usability and technology familiarity levels based on patients’ etiology or age, with no notable symptoms of cybersickness reported. Significantly strong correlations were noted between cybersickness symptoms and various usability categories, including exposure, motivation, interactivity, task specificity, and immersion aspects. Further, there was a significant association between the intervention time and the number of tasks performed (P<.001). Furthermore, patients who derived enjoyment from VR sessions expressed a heightened interest in incorporating VR into their daily neurorehabilitation practice (P<.001). Moreover, oculomotor issues were found to be highly sensitive to the onset of disorientation sickness symptoms (P<.001).

CONCLUSIONS

Through a collaborative approach, this study showcases the usability and feasibility of a VR-based support tool for cognitive rehabilitation among inpatients with ABI. Key components of such interventions encompass a multidisciplinary array of immersive experiences integrating neurorehabilitation principles and serious games techniques.

Published: March 2024

Background: To provide information on health services and education, hospitals require marketing communication, one of which is event. The hospital holds a variety of events for employees and citizen, which are routine or even incidental. Along with era development, hospitals are required to make fast and precise movements, so that performance is efficient and effective to achieve the success of events. President Director of RUMAH SAKIT Dr. OEN KANDANG SAPI SOLO (Droenska) decided to establish the Hospital Event Committee in 2019 with integrated system organization (ISO DOI) to replace the role of the event committee which is formed in every events. It is expected that the performance of each unit can be more effective, efficient, and the entire hospital community makes the culture of hospitals, internal marketers, as a way of life, because intangible marketing assets are important to embrace customers. After the Decision of the President Director is determined and implemented, of course, monitoring and evaluation are required.Purpose: Evaluating the effectiveness of events management which used Integrated System Organization RUMAH SAKIT Dr. OEN KANDANG SAPI SOLO (ISO DOI).Method: Qualitative descriptive research was used. The research datas were obtained through in-depth interviews with 17 informans who are choosen by purposive sampling selection method at the Hospital Event Committee in 2019–2020. Then it is formulated with the study of proposal recapitulation data as well as liability sheet (LPJ) in 2019–2020.Result: Component and function of Hospital events committee already fulfilled the standard of EO. The concept of events is quite good and clear. Coordination between the committees of events is inadequate due to a lack of communication and initiative. The event went smoothly and also there were no obstacles that led to the failure of the event, although there were still some shortcomings. Some of the event committees have not evaluated and given accountability (LPJ).Conclusion: The completeness of EO component’s and work function’s already exists and running on the Hospital Event Committee (ISO DOI). Events held by hospital with ISO DOI committees become more organized, effective, and efficient, but the function of coordination and evaluation must be improved. ISO DOI is potensial to develop as an event organizer that manage events with partners so that it can be additional revenue for Droenska.
