Published: September 2024

Objective: Lumbar foraminal stenosis can lead radiculopathy in a subset of patients. Imaging findings have a high false-positive rate. The Kemp test is a provocative maneuver that has traditionally been used for diagnosing facet joint disease. However, it has shown an increased likelihood of concomitant foraminal stenosis. Thus we evaluated the diagnostic accuracy of a modified version of Kemp test (the Singh-Hartl foraminal compression test) in the diagnosis of symptomatic foraminal stenosis.Methods: Fifty consecutive patients with radiculopathy were enrolled. Participants were asked to perform the Singh-Hartl foraminal compression test, with a positive result if there was reproduction of radicular symptoms. Selective nerve root block (SNRB) was then performed at the suspected level. Visual analogue scores (VAS) were collected before and 15-minutes postprocedure. VAS improvement was calculated as a percentage. Various statistical analyses were conducted considering 2 different threshold (75% or 80% improvement in VAS).Results: Twenty-eight participants (56%) were women, with an average age of 47.3 years. L4 was most commonly involved (n=20). Using 75% improvement as the VAS threshold, the test had a sensitivity of 0.72 (95% confidence interval [CI], 0.53–0.87), specificity of 0.57 (95% CI, 0.34–0.78), PPV of 0.70 (95% CI, 0.56–0.79), and NPV of 0.60 (95% CI, 0.43–0.75). When using 80% improvement as the VAS threshold, the test had a sensitivity of 0.64 (95% CI, 0.41–0.83), specificity of 0.43 (95% CI, 0.24–0.63), PPV of 0.47 (95% CI, 0.36–0.58), and NPV of 0.60 (95% CI, 0.43–0.75).Conclusion: The Singh-Hartl maneuver exhibited moderate to strong ability to rule-in the diagnosis and a moderate ability to rule out the diagnosis of foraminal stenosis when using a threshold of 75% improvement in radicular symptoms post-SNRB. Further studies evaluating the result of this physical examination test in conjunction with severity of imaging findings are warranted.
American superstar cities fade as remote work sparks migration southward and inland, exacerbating urban sprawl
Authors: Azhdari Abolghasem , Sigler Thomas , Pojani Dorina
Published: September 2024

The rise of remote work has impacted residential and employment location decisions significantly, as physical proximity is no longer necessary for many job functions. This study examines recent trends in employment and population distribution in the United States, focusing on the impact of work-from-home (WFH) in the post-COVID-19-pandemic era. Our findings reveal that the largest cities have experienced declines in their centres, while exurban and peri-urban counties – particularly in the Sunbelt – demonstrate resilience and growth. Counties with higher WFH adoption also perform better economically. Although WFH practices have not fully decoupled jobs and people, they have reinforced existing population growth patterns driven by lifestyle, affordability, taxation, and job opportunities.

Published: September 2024

The medial temporal lobe (MTL) is one of the key functional centers in the human brain, which participates in various higher-order cognitive functions, studies of brain connectivity in the MTL have received extensive attention. However, the brain network models have been used to be explored from the attributes of the whole-brain connectivity matrix. Brain local connectomes may be more valuable for analyzing the network mechanisms underlying brain functions and clinical neurological symptoms. Thus, in this study, we constructed the local structural connectomes for the MTL parcellations, included the amygdala, hippocampus, and parahippocampal gyrus, acquired the characteristics of the network topology parameters and the hubs distributions. Finally, we classified the major subtypes of these connectomes by hierarchical clustering, which demonstrated that the subtypes of these connectomes were closely related to the functions, providing a basis for further exploration of the functions and modifiable hubs within MTL parcellations.

Authors: Mao Min , Huang Rongzhi , Lai Shenglian
Published: September 2024

Background
Breast cancer (BC) is a typical females’ malignant tumors. Ubiquitin-proteasome system (UPS) is a critical pathway for pathogenesis of BC. Activation of UPS determined by SKP1–cullin 1–F-box protein (SCF) E3 ligase complexes. F-Box Protein 2 (FBXO2), a pivotal member of F-box proteins family, is related with UPS and mitophagy. FBXO2 have attracted increasing attention in multiple cancers. The relationship between FBXO2 and many cancers is still unclear. Therefore, systematic research on FBXO2 and pan-cancer is very important for the development and drug resistance of BC.
Method
Transcriptome expression data of 33 cancer types were acquired from the Cancer Genome Atlas (TCGA) database. Wilcoxon’s test was performed to estimate molecular characteristic of FBOX2 in human pan-cancer. To confirmed the relationship between FBXO2 and BC, mendelian randomization (MR) was performed. Kaplan–Meier (KM) curves to analyze the survival features of FBXO2. Additionally, the protein level and methylation level of FBXO2 was explored based on Wilcoxon’s test. Single cell sequence analyses were used to furtherly confirmed the importance of FBXO2. Finally, underlying mechanism of FBXO2 was explored from various perspectives, including gene function, immune checkpoint and tumor microenvironment.
Result
Our research revealed that FBXO2 expression were up-regulation in multiple cancers through pan-cancer analyses. It was first found to be downregulated in BC. MR analyses confirmed the caused relationship on FBXO2 and BC. Protein level analyses of FBXO2 revealed that FXBO2 was downregulated in BC. KM analyses indicated that Low FXBO2 expression had poor overall survival (OS) and recurrence free survival (DFS) in BC. Single cell sequence analyses revealed that FBXO2 obviously enriched in malignant epithelial cell. Our research unveiled that FBXO2 was a pivotal role in BC.
Conclusion
Comprehensive analysis unveiling immunological and promising potential value of FBXO2 in BC. It provided a new insight in pathogenesis of BC.

Published: September 2024

K2P (two-pore domain potassium) channels, a diversified class of K+-selective ion channels, have been found to affect a wide range of physiological processes in the body. Despite their established significance in regulating proliferation and differentiation in multiple cell types, K2P channels' specific role in adipogenic differentiation (adipogenesis) remains poorly understood. In this study, we investigated the engagement of K2P channels, specifically KCNK2 (also known as TREK-1), in adipogenesis using primary cultured adipocytes and TREK-1 knockout (KO) mice. Our findings showed that TREK-1 expression in adipocytes decreases substantially during adipogenesis. This typically causes an increased Ca2+ influx and alters the electrical potential of the cell membrane. Furthermore, we observed a reduction in differentiation and lipid accumulation in both 3T3-L1 cell lines and primary cultured adipocytes when the TREK-1 activity was blocked with Spadin, the specific inhibitors, and TREK-1 shRNA. Finally, our findings revealed that mice lacking TREK-1 gained more weight and had worse glucose tolerance when fed a high-fat diet (HFD) compared to the wild-type controls. These findings imply that TREK-1 plays an important role in the control of adipogenesis and could be a potential target for the development of therapeutic treatments for obesity.

Meniscus is a tissue that has vital properties for knee stabilization, shock absorption, axial load distribution, joint lubrication, and nutrition of articular cartilage. This study aims to produce loofah micro- and poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) nano-fiber integrated collagen and chitosan polymer-based composite hydrogel scaffolds crosslinked with three different concentrations of genipin (0.1, 0.3, and 0.5%) for meniscus regeneration. The scaffold crosslinked with 0.3% genipin, which exhibites the highest compression strength with high water absorption and damping capacities, is chosen as the optimal scaffold for further in vitro and in vivo analyses. In vitro biocompatibility studies are conducted by using rabbit bone marrow-derived mesenchymal stem cells. Accordingly, the composite hydrogel scaffold is found to be non-toxic, and capable of promoting cell adhesion and proliferation as well as collagen immunopositive, especially for type II collagen. In vivo analysis is performed by using 24 adult male New Zealand rabbits in three groups (empty defect, cell-free and cell-laden implanted scaffolds) with a standardized meniscus regeneration model. In conclusion, the cell-laden scaffold implanted group shows better meniscal healing based on the post-implantation biomechanical, histological, immunohistochemical, and Micro-CT evaluations.
Drivers of Farmers to Adopt Environmental Technologies: Development of an Integrated Model
Authors: Far somayeh Tohidyan , Rezaei-Moghaddam Kurosh , koochak Saeed Shokri
Published: September 2024

The increasing demand for food owing to population growth, the increase in the number of starving people, the lack of resources, the lowering of the water table and environmental pollution have put great pressure on developing countries to solve this problem by introducing and accepting environmentally friendly technologies. The aim of this study is to determine the effective factors on the intention to adoption of elite farmers in Fars Province, Iran, towards smart farming technologies using an integrated model to create conditions for the adoption of these technologies. The study was conducted using a survey and multistage random sampling in the Fars Province, Iran. The sample included 172 elite farmers in Fars Province. The results show that perceived usefulness, attitude toward behavior, self-efficacy, and personal innovativeness play an important role in shaping the intention to adoption. The study emphasized that perceived ease of use, perceived advantages of smart farming, smart farming knowledge, and controllability of behavior did not directly lead to the intention to adoption. Perceived usefulness also had the greatest influence on attitudes toward behavior. Short- and long-term training, workshops and research farm visits should be conducted to improve the intention to adoption of these technologies.
Knowledge mobilisation for translating evidence-based guidelines into practice. Lessons from using the Normalisation Process Theory to understand adherence to guidance on MgSO4 in preterm labou
Authors: Pithara-McKeown Christalla , Stone Tracey , Treloar Emma , Donovan Jenny , Luyt Karen , Redwood Sabi
Published: September 2024

Background
The administration of magnesium sulphate (MgSO4) in preterm labour is an evidence-based intervention recommended by the United Kingdom’s National Institute for Health and Care Excellence (NICE) to prevent neurological damage to the infant. However, uptake varies across UK maternity units. We used findings from implementation research in England, Scotland and Wales to explore knowledge mobilisation as a mechanism for improving adherence to clinical guidance.
Methods
Data were collected using semi-structured interviews for a process evaluation of the PReCePT (Preventing Cerebral Palsy in Pre-Term Labour) National Programme, the PReCePT cRCT study, and a study investigating MgSO4 guidance implementation in Scotland and Wales. Normalisation Process Theory informed data collection and analysis. Data were analysed using the framework method.
Results
Interviews with 68 strategic and clinical leads and implementers from the three nations suggested that despite evidence being necessary and important for policy decision-making, clinical leadership intervention decisions were motivated by audit data and benchmarking. Implementation success was impaired by degrees of silo working and rigid role boundaries, alongside differences in implementers’ ability to mobilise social-cognitive (e.g. commitment by maternity, neonatal and obstetric teams), and social-structural resources such as staff capacity, articulated workflows, and culture.
Cross-organisational, diverse and collaborative communities of practice (CoPs) rooted in distributed leadership created a nexus between national and regional leadership, patient group representatives, implementers i.e. clinical leads and champions, and perinatal clinical teams. They provided a platform for CoP participants to build relationships and share knowledge, and together negotiate meaning, co-design implementation plans, share operational enablers such as strategies and products, and assess progress. Where training opportunities were provided alongside mentoring and peer support, CoPs created implementation resource i.e. capacity and capability within the perinatal system. Backfill funding for champions and protected time away from clinical duties were required to enable participation, especially for champions in resource-poor settings.
Conclusions
Opportunities to participate in collaborative, diverse, cross-organisational CoPs where knowledge and innovation can be co-created, shared, and spread across the perinatal ecosystem, can help address disparities in clinical teams’ ability to implement evidence-based interventions. Participation relies on backfill funding for champions, and a system-wide commitment to improvement.

The widespread adoption of Electronic Health Records (EHRs) and deep learning, particularly through Self-Supervised Representation Learning (SSRL) for categorical data, has transformed clinical decision-making. This scoping review, following PRISMA-ScR guidelines, examines 46 studies published from January 2019 to April 2024 across databases including PubMed, MEDLINE, Embase, ACM, and Web of Science, focusing on SSRL for unlabeled categorical EHR data. The review systematically assesses research trends in building efficient representations for medical tasks, identifying major trends in model families: Transformer-based (43%), Autoencoder-based (28%), and Graph Neural Network-based (17%) models. The analysis highlights scenarios where healthcare institutions can leverage or develop SSRL technologies. It also addresses current limitations in assessing the impact of these technologies and identifies research opportunities to enhance their influence on clinical practice.

Published: September 2024

This study delves into the intricate correlation between emotional intelligence and employee performance within the dynamic setting of Saudi small and medium enterprises. Acknowledging the increasing importance of emotional intelligence in the workplace, this study examines how emotional intelligence influences employee performance, with particular attention to the mediating role of organizational citizenship behavior. Employing a comprehensive research framework, the study integrates quantitative methods to analyze data collected from 248 employees across various Saudi-based small and medium enterprises. The findings indicate that high emotional intelligence enhances employee performance, with organizational citizenship behavior serving as a crucial mediator, strengthening the positive impact of emotional intelligence on performance. The results demonstrated a robust positive correlation with organizational citizenship behavior (β = 0.719***) and a moderate positive correlation with employee performance (β = 0.314***). In addition, organizational citizenship behavior played a significant positive mediating role between employee intelligence and employee performance (β = 0.397***). This suggests a nuanced interplay among emotional intelligence, organizational citizenship behavior, and overall employee performance within the specific context of Saudi small and medium enterprises.

Blending Ensemble applied to Open-Set Recognition for Time Series Classification
Authors: Marques Leonardo , Lazzaretti André Eugenio , Lopes Heitor
Published: September 2024

Time Series (TS), including stock prices, temperatures, and health markers are monitored all the time and everywhere. Time-dependent events, and TS are frequently studied in the scope of forecasting, where past values of the TS are used to preview future ones. On the other hand, Time Series Classification (TSC) aims at creating models that label TS instances. Open Set Recognition (OSR) techniques, designed to classify known samples and detect unknowns simultaneously, have been less applied in TSC compared to other fields like image classification. Existing methods have limitations, such as not using known-unknown in the training stage, limited transfer learning across Neural Network models, and experiments with benchmark datasets with narrow coverage. This study introduces a novel OSR approach for TSC by addressing the mentioned issues and using a blending ensemble of Neural Networks with an OpenMax layer. The results vouch for the model’s performance and potential superiority as an alternative to existing methods in open-set recognition tasks.

Published: September 2024

Point clouds generated in simulators avoid collection time costs and provide a high and organized amount of point clouds, an ideal scenario for deep learning networks. However, these networks have limitations when applied to real point clouds. This work proposes a multilayer perceptron-based method to classify 3D objects based on real point clouds obtained using LiDAR sensors. The method includes a pre-processing step that normalizes and adjusts the point clouds in the 3D Cartesian plane to overcome discrepancies in the point distribution. Furthermore, we created a dataset and used the ModelNet dataset for comparison purposes. The proposed neural network, Lidar3DNetV2, achieved 98.47% and 125 μs in accuracy and test time with real data, respectively. The pre-processing step provided a significant increase in the classifier’s performance. Finally, the proposed method performs better than other state-of-the-art networks considering real point clouds.

Published: September 2024

Este estudo tem como objetivo analisar os desafios enfrentados pelos Conselhos Tutelares na efetivação e na garantia dos direitos da criança e do adolescente, na microrregião de Manhuaçu – MG, tendo como parâmetro legal as diretrizes estabelecidas na Lei nº 8.069/90. Para tal análise, pontuam-se as discussões em torno da Política de Atenção a Criança e ao Adolescente; a relação do Conselho Tutelar, Conselho Municipal dos Direitos da Criança e do Adolescente e Administração Municipal. Para a realização da pesquisa, utilizou-se de informações coletadas através de questionário dirigido aos representantes de oito Conselhos Tutelares da região, fundamentados em uma análise crítica sob a legitimidade e atribuições dos Conselhos Tutelares da microrregião de Manhuaçu-MG. Contudo, conclui-se que apesar de vinte quatro anos de ECRIAD, o Conselho Tutelar, órgão de extrema importância e relevância política para a criança e o adolescente, não consegue ainda se legitimar como órgão de garantia de direitos. Já que suas ações são pautadas na fragmentação e, muitas vezes interrompida, devido aos interesses políticos, econômicos e culturais dos municípios. O desafio que se põe é reforçar a garantia do direito amparados na legislação, mesmo que a realidade dos Conselhos Tutelares seja contraditória e conflitante.

Lançando mão dos documentos fornecidos pela Secretaria Nacional de Educação, os Parâmetros Curriculares Nacionais do Ensino Fundamental e Médio, encontram-se diversos meios e sugestões para aplicação das novas metodologias de ensino, uma vez que o conhecimento não pode mais ser dividido, compartimentado; mas devem buscar sempre a integração e o desenvolvimento das capacidades de assimilação dos conteúdos e a associação com outras disciplinas e o quotidiano.
O VALOR CAUSATIVO DO PREFIXO [DES-]: UM ESTUDO LÉXICO-SEMÂNTICO
Authors: Buthers Chritiane Miranda
Published: September 2024

O objetivo desta pesquisa é proceder à análise do prefixo [des-], segundo as acepções semânticas que podem ser refletidas nesse morfema. Pretende-se investigar os predicados que figuram com esse prefixo, delineando os valores semânticos específicos atribuídos à base lexical com a qual se conecta. Adicionalmente, implementamos o sentido “causativo” que [des-] impõe sobre os verbos com os quais pode ser combinado, como, por exemplo: desacelerar, desativar, desorganizar, desinquietar, entre outros. Com o sentido causativo, [des-] pressupõe uma estrutura bieventiva, contendo um evento causado (evento 1)  que será modificado  pelo evento da causação (evento 2). O enfoque deste artigo contempla, então, a interface do léxico com a semântica e a sintaxe. Observamos que o prefixo [des-] causativo se conecta a predicados de estado, atividade, processo e criação. Nessas circunstâncias, dois eventos estarão envolvidos, já que o prefixo [des-] seria responsável por introduzir o evento da causação (evento 2). Ressaltamos que esses mesmos predicados podem figurar com o prefixo [des-] não causativo. Quando isso ocorre, apenas um evento estará envolvido na predicação. Utilizando de estratégias de descrição da teoria gerativa e da proposta assumida por Pylkkänen (2002) – espraiamento do núcleo vo com a inserção do núcleo Causeo para as construções causativas –, verificamos que [des-] causativo é a realização morfológica do núcleo Causeo. Dessa maneira, esse prefixo cumpre a função de introduzir o segundo evento na predicação. Adicionalmente, assumimos que o causativo [des-] possui uma contraparte negativa, além do traço estativo, o qual será atribuído ao primeiro evento. Essa combinação motiva a mudança de estado desse evento.

Food contamination is a public health problem, and the search for natural additives to increase food stability and safety is challenging. This research aimed to study nanoemulsions produced with coriander essential oil and kefiran, an exopolysaccharide extracted from kefir grains. The composition of coriander essential oil was evaluated, revealing linalool as the main component. An experimental design consisting of six trials was conducted. The NE2 formulation (0.5% kefiran and 1.5% coriander essential oil) exhibited smaller particle size, monodispersity, a lower centrifugal stability coefficient, and higher absolute zeta potential values (> 30 mV), indicating high electrical stability. Morphology, thermal stability, and toxicity tests were performed. The minimum bactericidal concentration was determined and applied to commercial cheese. Thermal stability tests demonstrated an increase in the stability of NE2 compared to its individual components, and it was also proven to be non-toxic. The concentration of 25% m v-1 was identified as the minimum bactericidal concentration and was applied to commercial cheese.

Authors: Yu Lei , Gong Shuxin , Liang Jing
Published: September 2024

How to treat phenol-containing wastewater harmlessly is an urgent problem to be solved. In this study, a kind of biomaterial was prepared through strain PAO1 immobilized on aminated straw to enhance the phenol removal rate and efficiency. The aminated straw assisted PAO1 to increase the phenol degraded concentration from 1,900 to 1,500 mg/L, and shorten the degraded time by 44 h at 1,500 mg/L phenol. The immobilized PAO1 could remove phenol at pH 10 and 11, which was 2.7 and 3.8 times higher than free bacteria, respectively. In addition, the immobilized PAO1 could totally remove phenol, which was twice as high as that of free bacteria, at 4% NaCl stress. Furthermore, the removal efficiency of immobilized PAO1 was higher than that of free bacteria under the stress of various metal ions, especially for Co2+ and Pb2+. The determination coefficients R2 and root mean square error showed that the back propagation artificial neural network model could predict the degradation of phenol under various conditions, saving time and economic cost. The present study envisions that this biomaterial has great potential in the bioremediation of organic pollutions.

Published: September 2024

Introduction:

Iron oxide nanoparticles demonstrate tremendous potential in preserving
the ecological balance of the environment since they act as antimicrobial agents and efficient photocatalysts.
However, environmental sustainability has challenged the synthesis protocols of nanomaterials.

Methods:

This study compares the green synthesis method with the scalable chemical synthesis
method. In this work, Iron oxide nanoparticles were fabricated via the green chemistry technique
utilizing the leaf extract of Mentha spicata (M-IONP) and also via the chemical co-precipitation
method (C-IONP). The synthesized IONPs were analyzed by different characterization methods
such as XRD, FTIR, SEM analysis, ZETA potential measurements, and DLS spectroscopy analysis.

Results:

The biosynthesized and chemically synthesized IONPs were analyzed for their mechanistic
action against different applications like antimicrobial, antioxidant, and degradation of harmful
dyes. Interestingly, the biosynthesized IONPs (M-IONP) exhibited more effective antimicrobial
efficacy towards Gram-positive and Gram-negative organisms than chemically synthesized
IONPs.

Conclusion:

The green synthesized M-IONP also showed significant antioxidant propensity similar
to that of the standards taken. Additionally, green-synthesized M-IONP exhibited enhanced
degradation efficacies against Methylene blue, chromium, and sulphamethoxazole in comparison
to chemically synthesized IONP.

Published: September 2024

Background

Despite the increased interest from researchers in Postpartum depression (PPD) globally, related studies are limited in Palestine and do not provide a comprehensive understanding of PPD.

Objective

We examined the factors that determine post-partum depression among Palestinian mothers in Hebron governorate.

Methods

A cross-sectional study was conducted in 122 governmental primary healthcare clinics in Hebron Governorate. A convenient sampling method was used to collect data from 435 using a self-administered questionnaire using the Edinburg Postnatal Depression Scale.

Results

The mean EPDS scale score was 10.56 (SD 5.273), and 36.1% had a score of ≥13, indicating moderate-to-severe depression symptoms. The study results revealed that psychosocial factors were significantly associated with PPDS and play a crucial role in the development of PPD, such as the history of depression, being exposed to domestic violence before and during pregnancy, poor husband support, unplanned pregnancy, fear of infant’s gender, and in addition to anemia than other factors.

Conclusion

A high prevalence of PPD was found among Palestinian women in this study. The study proposes screening women for trauma or domestic violence and assessing their social support, inquiring about pregnancy intention, and discussing family planning. Delivering iron supplements to pregnant or postpartum anemic women is important. Women who have a history of depression, domestic abuse, or lack social support should receive psychological and medical treatment. Mental health services must be included in the after-birth care protocol to train primary health clinic staff to recognize and treat PPD.

Published: September 2024

Background:

Recorded brain activity analysis is a major tool used in modern medicine
and sleep-based research. However, the volume and complexity of the data make manual
investigation difficult. Furthermore, high inter-subject variability presents a challenge to deep
learning techniques, especially in the detection of sleep-related EEG patterns and artifacts.

Methods:

Sleep Pattern Identifier (SPI), a hybrid classifier, was used in this study to address
the aforementioned issues. SPI tests the efficacy of artifact detection while examining strategies
and tactics used in real-world sleep research. A focus was on inter-subject variability, especially
in data gathered from participants suffering from sleep disorders. For comparison and
visual inspection of the data, formal statistical measures like accuracy, model loss, precision,
recall, and ROC were employed.

Results:

With an accuracy of 94.85%, the suggested model outperformed current techniques
and demonstrated higher accuracy. Further, the Sleep-EDF dataset was used in this investigation.

Conclusion:

The conclusion highlights the effectiveness of the SPI hybrid classifier in identifying
EEG patterns, especially in situations where sleep research is conducted in the real
world. Research methodologies based on sleep have made significant progress in handling artifacts
and adapting to inter-subject variability.
