: Carbapenem-resistant Enterobacterales (CRE) are a significant public health threat due to their resistance to antibiotics, leading to serious infections, increased healthcare expenses, and higher mortality rates. Accurate identification of CRE is essential for effective treatment and infection control. Phenotypic methods like the modified Carbapenemase Inactivation Method (mCIM) and the EDTA-Carbapenem Inactivation Method (eCIM) are practical approaches for identifying production carbapenemase. As a result, the current study aims to analyse the efficacy of phenotypic carbapenem inactivation approaches in detecting carbapenem-resistant Gram-negative bacteria isolated from blood culture specimens, as well as the synergy of ceftazidime-avibactam and aztreonam in treating such infections. This laboratory based prospective study was adopted to evaluate the efficacy of phenotypic carbapenem inactivation methods in detecting carbapenem-resistant Gram-negative bacteria isolated from blood culture specimens and assess the synergy of ceftazidime-avibactam and aztreonam in treating these infections.: Gram-negative bacteria isolated from positive blood cultures were evaluated for carbapenemase activity using mCIM and eCIM, respectively. Synergy testing was conducted using ceftazidime-avibactam and aztreonam to evaluate potential therapeutic benefits. Among 383 blood cultures, 153 (39.94%) were MDROs, predominantly (57.5%). Of these, 123 (81%) were carbapenem-resistant. The mCIM and eCIM tests identified 67 (54%) serine carbapenemase and 54 (45.5%) metallo beta-lactamases. Synergy testing with ceftazidime-avibactam and aztreonam showed positive results in 43 (68.25%) of the 63 CZA-resistant isolates.: The study confirms that mCIM and eCIM tests effectively detect carbapenemase production in blood culture isolates, identifying 54% serine carbapenemases and 45.5% metallo beta-lactamases. Additionally, synergy testing with ceftazidime-avibactam and aztreonam demonstrated a 68.25% success rate in CZA-resistant isolates, indicating a promising treatment option for these resistant infections.

Published: September 2024

Telemedicine has emerged as a transformative force in dentistry, revolutionizing the way oral healthcare is delivered. By leveraging technology, telemedicine offers a convenient, accessible, and often cost-effective approach to dental care. Patients can now connect with dental professionals remotely for a variety of services, including consultations, diagnostics, education, and even emergency care.One of the most significant benefits of telemedicine in dentistry is its ability to expand access to care. In underserved areas, where dental professionals may be scarce, telemedicine can bridge the gap by connecting patients with experts located elsewhere. This is particularly important for those who face geographic, financial, or mobility barriers.Moreover, telemedicine can improve patient convenience. Patients no longer need to travel long distances or wait for appointments, as many services can be provided virtually. This is especially valuable for individuals with busy schedules or those who live in remote regions.In addition to accessibility and convenience, telemedicine can also enhance the quality of dental care. By enabling remote consultations with specialists, patients can receive expert opinions and guidance on complex cases. Additionally, telemedicine can facilitate the sharing of information and best practices among dental professionals, leading to improved treatment outcomes.

Published: September 2024

Os anos de 2020 e 2021 foram marcados pela pandemia da Covid-19 e a necessidade de isolamento social. Diante deste cenário, as Instituições de Ensino Superior (IES) propuseram a utilização de novas estratégias a fim de manter o aprendizado do discente e, por isso, a maioria das universidades no Brasil optou pelas aulas remotas. Este artigo objetiva analisar quais são os fatores promotores da motivação dos estudantes do curso de Ciências Contábeis, de uma universidade privada da cidade do Rio de Janeiro, tendo como cenário as aulas remotas, sob a perspectiva da teoria da autodeterminação. A metodologia teve abordagem qualitativa, descritiva, com entrevista em profundidade, com um corpus formado por 12 estudantes de quarto período de Ciências Contábeis do semestre 2021.1. Os resultados demonstraram que a maioria dos alunos apresentou motivação autônoma para o estudo, sendo seis com motivação intrínseca. Nesse sentido, foi possível perceber que os fatores ambientais e pessoais afetam a motivação intrínseca dos alunos, e que seus comportamentos são guiados por contextos que fornecem contribuições às necessidades psicológicas, o que demanda dos indivíduos competências que podem variar o nível e tipo de motivação.

Review of the Influences of Sex Differences on Health and Disease: What Is the Role of Journals?
Authors: Regensteiner Judith G. , Templeton Kimberly 
Published: September 2024

➢ Sex-based differences are understudied, which has potential consequences for the health of everyone.➢ Women’s health is particularly affected given a lack of sex-specific data across many disease states.➢ Journals do not consistently require the inclusion of both sexes and the disaggregation of data by sex in cell, animal model, and human studies.➢ Instructions for investigators and journals regarding the inclusion of sex-specific data are found in guidelines such as those by the Sex and Gender Equity in Research (SAGER) group, but these guidelines are underutilized.➢ Consistency in the inclusion of both sexes in studies (except in studies on diseases affecting only 1 sex), as well as in the disaggregation and reporting of results by sex, has the potential to improve health for all people.

Authors: McAuliffe Michael , Darwish Ibrahim , Anderson Jon , Nicholls Alex , Corfield Sophie , Harries Dylan , Vertullo Christopher 
Published: September 2024

Background:
Technology (navigation and robotics) usage during total knee arthroplasty (TKA) is often supported by literature involving high-volume surgeons and hospitals, but the value of technology for lower-volume surgeons is uncertain. This study aimed to determine if there was a relationship among surgeon volume, technology usage, and revision rate when using an optimal prosthesis combination (OPC).

Methods:
Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) data were obtained from January 1, 2008, to December 31, 2022, for all primary TKA procedures performed for osteoarthritis using an OPC by a known surgeon ≥5 years after their first recorded procedure. The interaction between surgeon volume and conventional-instrumentation (CV) versus technology-assisted (TA) TKA was assessed. The cumulative percent revision (CPR) was determined by Kaplan-Meier estimates. Cox proportional-hazards methods were used to compare rates of revision by surgeon volume and by the interaction of volume and technology. Subanalyses were undertaken to examine major and minor revisions separately, and to assess the influence of technology on revision rates relative to those of a surgeon undertaking 100 TKA/year.

Results:
Of the 53,264 procedures that met the inclusion criteria, 31,536 were TA-TKA and 21,728 were CV-TKA. Use of technology reduced the all-cause revision rate for surgeons with a volume of <50 TKA/year and the rate of minor revisions for surgeons with a volume of <40 TKA/year. No interaction between surgeon volume and the rate of major revision surgery was found. With CV-TKA by a surgeon with a 100-TKA/year volume as the comparator, all-cause and major revision rates were significantly elevated for surgeons undertaking <50 and <100 TKA/year, respectively. In contrast, analysis of TA-TKA showed no difference in rates of all-cause or major revisions for surgeons undertaking <100 TKA/year compared with 100 TKA/year.

Conclusions:
TA-TKA was associated with a decrease in the revision rate for lower-volume surgeons but no significant alterations in revision rate for higher-volume surgeons. Preferential use of TA-TKA by lower-volume surgeons should be considered.

Published: September 2024

Abstract

The prognosis of brain tumor diseases is essential for effective treatment planning and patient management. This study investigates the use of Dense EfficientNet models, specifically an enhanced EfficientNet-B1, for the prognostication of multiclass brain tumor diseases. A dataset comprising 6462 MR images, including T1-W, T2-W, and FLAIR sequences, was classified into four categories: glioma, meningioma, no tumor, and pituitary tumors. The proposed method incorporates advanced data augmentation techniques, image cropping, and pixel resizing to improve training accuracy. Additionally, modifications to the EfficientNet architecture layers and the application of normalization and histogram equalization further enhance model performance.The results indicate that the enhanced EfficientNet-B1 model achieves a superior training accuracy of 98%, outperforming the EfficientNet-B0 model, with the highest accuracy observed in glioma tumor classification. Compared with other CNN architectures, such as ResNet50 and VGG-16, the EfficientNet-B1 model demonstrates higher performance and computational efficiency with fewer parameters.The study concludes that the enhanced EfficientNet-B1 model offers a robust and efficient solution for brain tumor detection and prognostication using MR images. Its innovative modifications and advanced preprocessing techniques significantly contribute to its high performance, making it a valuable tool for developing clinically useful applications for MR image analysis in brain tumor management.

Published: September 2024

Abstract

Background: Telehealth and virtual supervision practices in health professions clinical education has grown rapidly, including in the Department of Veterans Affairs (VA) which oversees the largest interprofessional training effort in the United States. Telehealth is the provision of healthcare that is provided remotely through telecommunication technology, and virtual supervision is clinical supervision of health professions trainees (HPTs) that occurs through telecommunication technology. In this study we evaluate participation in telehealth and virtual supervision for physician, nursing, and associated health HPTs, and describe prevalent themes concerning HPT perceptions of telehealth and virtual supervision.
Methods: The survey study cohort included 10,865 HPTs that responded to the 2023 VA Trainee Satisfaction Survey. Descriptive and bivariate analyses were conducted to evaluate participation rates by profession. Responses to the open-ended question within the survey were coded and summarized using rapid qualitative analysis methods.
Results: Participation rates for telehealth and virtual supervision were associated health HPTs (47.2% telehealth, 33.8% virtual supervision), physician residents (31.1% telehealth, 21.5% virtual supervision), and nursing HPTs (22.9% telehealth, 21.5% virtual supervision) (p<.001). HPTs of all professions expressed positive views on their experiences, with profession-specific differences noted in location, frequency and depth of these practices.
Conclusions: Participation in telehealth and virtual supervision was common and well received by HPTs across multiple professions in VA. HPT responses suggest additional efforts are needed to refine profession-specific instructional methods tailored for defined educational needs and goals.

Published: September 2024

Abstract

Syzygium cinereum (Kurz) Chantar. & J.Parn. (1993), Syzygium cumini (L.) Skeels (1912), and Syzygium grande (Wight) Walp. (1843) have different usages by humans as foods or medicines in the Southeast Asia regions. In this study, we assembled and characterized the complete chloroplast (cp) genome of three Syzygium species. The complete cp genomes of S. cinereum, S. cumini and S. grande were 158,956 bp, 158,448 bp, and 159,061 bp in length, respectively, with the overall GC content of 37.0%. All three Syzygium cp genomes consisted of 130 genes in total (including 85 protein-coding genes, 37 transfer RNA genes, and 8 ribosomal RNA genes). A phylogenetic tree based on cp protein-coding regions revealed the monophyly of Syzygium species and provided valuable insights into the phylogenetic relationships of three of our Syzygium species with other Myrtaceae species. The sequencing of this cp stands to expedite the development of molecular markers and significantly contribute to genetic research involving this distinctive plant.
Nitrogen-Doped Graphene Quantum Dots for Enhanced Oil Recovery: The Effects of Precursor Type, Molar Ratio, and Synthesis Duration on Interfacial Tension Reduction
Authors: Gholamzadeh Younes , Hemmati-Sarapardeh Abdolhossein , Sharifi Mohammad 
Published: September 2024

Abstract

Nanofluids have the capacity to reduce interfacial tension (IFT) of crude oil and water for enhanced oil recovery (EOR) operations, but traditional nanoparticles are limited in tight reservoirs due to their inappropriate size for micro-nano pores and their tendency to aggregate. In this paper, Graphene Quantum Dots (GQDs) with simple and favorable properties are developed, and their performance and mechanism for reducing IFT are evaluated. The paper also aims to explore the effects of GQD precursor type, synthesis duration, and molar percentages of precursors on reducing IFT. For this purpose, citric acid was used as a carbon source, and ethylenediamine, urea, and thiourea were used as nitrogen sources to synthesize different GQDs. FTIR, XPS, HR-TEM, XRD, UV visible, and PL photoluminescence were used to identify the GQDs' characteristics. The highest IFT reduction value is achieved by using 1000 ppm ethylenediamine-derived GQDs, which reduces the IFT from 19.03 to 0.70 mN/m at 200000 ppm NaCl concentrations without using any surfactants. The XPS analysis revealed that ethylenediamine-derived GQDs exhibit higher pyrrolic nitrogen content and a relative intensity ratio of sp3 C/sp2 C. It has been identified that the presence of more polar atomic bonds on the surfaces of GQDs decreases the ability of GQDs to reduce IFT. In this way, urea-derived and thiourea-derived GQDs exhibit less capability for IFT reductions from 19.03 to 12.33 and 18.04 mN/m at 1000 ppm GQDs and 200000 ppm NaCl concentration, respectively. Furthermore, ethylenediamine-derived and urea-derived GQDs perform optimally at approximately 5 and 10 hours, respectively, with a precursor molar ratio of 3 (mole ethylenediamine/urea per mole citric acid), while thiourea-derived GQDs show no significant IFT change with varying synthesis times or precursor molar ratio. The developed GQDs provide a promising solution for EOR operations in unconventional reservoirs by significantly decreasing the IFT between crude oil and nanofluids.
Broadband surface enhanced infrared absorption with multiple Fano resonance by metallic oblique-wire-bundle metamaterial absorbers

Published: September 2024

Abstract

Higher sensitivity with specific recognition of a sensor could ease the burden of sample purification or labelling procedure for specific testing and detection and there appear two methods including surface enhanced infrared absorption (SEIRA) and surface enhanced Raman scattering (SERS), promising better sensitivity and specificity, simultaneously, via detection of molecular footprints. Furthermore, researchers employ Fano resonance to further boost the detection limit of SEIRA by coupling between the two absorption bands from molecules and metamaterials. Still, the current metamaterial absorbers are almost narrow band and required specific design, only suitable for limited chemicals. Thus, in this work, we would like to design a broadband oblique-wire-bundle (OWB) metamaterial absorbers (MA) which could interact with multiple functional groups’ absorption from a sample, thus easing the burden of custom-made resonators. In experiments, indeed, our designed OWB MA developed four Fano resonance responses with three PMMAs’ functional groups and one function group from carbon dioxide. The counterpart planar MA also performed SEIRA yet without occurrence of Fano resonance as a comparison. We believe this proposed OWB MA could facilitate the development of rapid detection in the field of food safety and chemical detection.

Published: September 2024

Abstract

The Scorpaeniformes order encompasses a diverse array of teleost fish, including commercially important and venomous species. Fish venoms offer significant pharmacological potential, but incomplete phylogenetic understanding has hindered research. Resolving relationships among venomous fish families is crucial for studying venom evolution and discovering novel bioactive compounds. To address these phylogenetic uncertainties, we generated and assembled the complete mitochondrial genomes of Paracentropogon rubripinnis (Tetrarogidae) and Inimicus japonicus (Synanceiidae), two representative venomous species. The circular mitogenomes, 16,465 bp and 16,676 bp in length, respectively, contain the typical vertebrate mitochondrial gene complement. Comparative analyses revealed a highly conserved gene order and orientation across Scorpaeniformes, with slight variations in the Notothenioidei outgroups. We identified novel conserved sequence blocks in the control regions and characterized structural features of protein-coding genes, tRNAs, and non-coding elements. Phylogenetic analyses using 13 mitochondrial protein-coding genes from 71 Scorpaeniformes and three outgroup species provided a higher-resolution phylogeny of the order, including 12 families and 31 genera. Our results support the monophyly of Tetrarogidae and Synanceiidae, placing them at the base of the Scorpaeniformes phylogeny. This study provides new insights into Scorpaeniformes evolution, particularly regarding venomous fish families, and lays a foundation for future research on fish venom evolution and applications.

Published: September 2024

Abstract

The multiband, multifunctional chiral metasurface with asymmetric transmission exhibits significant potential for diverse applications in modern communication systems, ranging from enhanced signal modulation and polarization control to advanced beam steering and compact antenna design. This research presents a versatile and advanced chiral metasurface operating at multiple bands with diverse functionalities, including asymmetric transmission. The proposed metasurface effectively transforms an incoming Linearly Polarized (LP) wave into a Circularly Polarized (CP) wave. Additionally, it functions as a 90° polarization rotator for the incident LP wave. The design starts with an element of a 2 × 2 supercell comprising a Square Split Ring Resonator (SSRR) and an I-shaped resonator. The right diagonal elements of a supercell undergo scaling down, giving rise to a rotational asymmetry. Chirality is introduced into the design, and cross polarization conversion is enhanced by rotating all four elements by 90° relative to each other. On the back side of the substrate, each element undergoes a 90° rotation compared to its counterpart on the front side, realizing the asymmetric transmission feature. The incorporation of multiband and multifunctional features within a single supercell equips the subject chiral metasurface to be utilized in various engineering applications.
