Published: November 2024

The utilization of 20CrNiMo/Incoloy 825 composite materials as high-pressure pipe manifold steel can not only improve the strength and hardness of the steel, but also improve its corrosion resistance. However, research on the heat treatment of 20CrNiMo/Incoloy 825 composite materials is still scarce. Thus, the aim of this study was to investigate the influence of solid solution treatment on the microstructure and properties of 20CrNiMo/Incoloy 825 composite materials. Firstly, the composite materials were subjected to solid solution treatment at temperatures ranging from 850 to 1100 °C with varied holding times of 1 h, 4 h, and 6 h. Microstructural analysis revealed that the solid solution treatment temperature had a more pronounced effect than the treatment time on the interface decarburization layer, carburization layer, and grain size. It was observed that the carburized layer thickness decreased while the decarburized layer thickness increased with an increase in the solid solution treatment temperature, oil cooling was found to enhance the hardness of the base layer of the composite materials, and the size of the original austenite grains of 20CrNiMo steel and Incoloy 825 increased with an increase in the solid solution treatment temperature. Secondly, the tensile properties, microhardness, and fracture morphology were evaluated after the composite materials underwent solid solution treatment at temperatures between 950 °C and 1100 °C for 1 h. The results indicated that increasing the solution temperature initially led to an increase in tensile strength and elongation after fracture, followed by a decrease; furthermore, the hardness of Incoloy 825 exhibited a declining trend, while the hardness of 20CrNiMo first decreased then increased. Thirdly, the shear properties and interfacial element diffusion of the composite materials were analyzed following solid solution treatment in a temperature range of 950 °C to 1100 °C for 1 h. The findings demonstrated that higher solid solution treatment temperatures induced full diffusion of Cr, Ni, and Fe atoms at the interface and softened the matrix, leading to an increase in the thickness of the diffusion layer and toughening of the composite interface. Therefore, the shear strength increased with an increase in the solid solution treatment temperature. Finally, the optimal solid solution treatment process for 20CrNiMo/Incoloy 825 composite materials was determined to be 1050 °C/1 h oil cooling, following which the composite materials had good comprehensive mechanical properties.

Published: November 2024

Ti matrix composites (TMCs) are promising structural materials that meet the increasing demands for light weight the automobile and aircraft industries. However, the room temperature brittleness in the traditionally homogeneous reinforcement distribution of TMCs limits their application in high-strain-rate impact environments. In the present study, novel bilayer TMCs with hierarchical microstructures were designed by the laminated combination of graphene nanoplatelet (GNPs) reinforced TC4 (Ti-6Al-4V) composites (GNPs/TC4) and a monolithic TC4. Meanwhile, the configuration of the microstructure, impact performance V50, and deformation modes of the bilayered TC4-(GNPs/TC4) plate was investigated. The plates were fabricated via field-assisted sintering technology (FAST). It turned out that the TC4-(GNPs/TC4) plate with a 7.5 mm thickness against a 7.62 mm projectile exhibited greater impact performance (V50~825 m/s) compared to the TC4 and GNPs/TC4 single-layer plates. The plate failure modes were dependent on the microstructure while the failure behaviors seemed to be influenced by the hierarchical configuration. This work provided a new strategy for utilizing TMCs in the field of high-strain-rate impact environments.

Published: November 2024

It is challenging to deliver therapeutics in the oral environment due to the wet surfaces, the nature of the mucosa and the potential for saliva washout. In this study, the development of a mucoadhesive dimethicone-based oral carrier system for adhesion to the hard tissue and mucosa in the mouth was examined. This study reports the viscosity and mucoadhesion of dimethicone based polymer blends. The viscosity of the materials was measured using a rheometer. The mucoadhesion of these materials was determined as the work of adhesion and peak tack force using the tensile test method with a texture analyzer. Materials were prepared with either calcium and phosphate salts or sodium fluoride as potential therapeutics for promoting remineralization and treating dentin hypersensitivity by mechanical occlusion. Scanning electron microscopy was used to look at mineral deposition on the surface of dental hard tissue after the application of the dimethicone-based formulations. The results of this study confirm the potential for using these dimethicone-based materials as mucoadhesive therapeutic delivery systems in the oral environment.

Published: November 2024

The drilling of State-of-the-Art printed circuit boards (PCBs) often leads to shortened tool lifetime and low drilling accuracy due to improved strength of the PCB composites with nanofillers and higher thickness-to-hole diameter ratio. Diamond coatings have been employed to improve the tool lifetime and drilling accuracy, but the coated microdrills are brittle and suffer from coating delamination. To date, it is still difficult to deposit diamonds on ultrathin microdrills with diameters lower than 0.2 mm. To avoid tool failure, the pretreatment was optimized to afford sufficient fracture strength and enough removal of cobalt. Further, the adhesion of the diamond coating was improved by employing an interlayer comprising SiC/microcrystalline diamond, which mitigates stress accumulation at the interface. By these means, microdrills with diameters of 0.8 and 0.125 mm were coated with adherent diamonds. In this context, the composite coating with the diamond/SiC interlayer and a nanodiamond top layer featured enhanced adhesion compared to single nano- or microdiamond coatings on the WC-Co microdrills. The composite diamond-coated WC-Co microdrills featured improved wear resistance, resistance to delamination of the diamond coating, and improved performance for drilling PCBs compared to micro- and nanodiamond-coated microdrills without interlayer. In addition, a higher hole quality was achieved when the diamond-coated microdrills were used. These results signify that the composite/nanodiamond coating features the highest bonding strength and best drilling performance.

Published: November 2024

Coating conductive nanoparticles onto the surface of hollow glass microspheres (HGMs) is essential for broadening their applications. However, the low density and high specific surface area of HGM powders, along with the thin walls of the cavity shells and poor surface adhesion, pose challenges for the uniform attachment of functional particles. In this study, we developed a novel integrated process that combines flotation, hydroxylation, and amination pretreatment for HGMs with in situ surface polymerization to achieve a uniform coating of polypyrrole (PPy) on the surface of HGMs. We explored the corresponding growth process and coating mechanism. Our findings indicate that the amount of coating, particle size, and uniformity of PPy on the surface of HGMs are significantly influenced by the pretreatment and the in situ polymerization time, as well as the microspheres/pyrrole feedstock ratio. The in situ polymerization on the surface of HGMs resulted in a uniform encapsulation of spherical PPy, with the average particle size of PPy-coated HGMs (PPy@HGMs) increasing by 14.60% compared to the original HGMs. The elemental nitrogen in the PPy@HGMs primarily exists in the form of C-N and N-H bonds. This study demonstrates that the surface functional groups of HGMs engage in chemical bonding and interactions with PPy molecules. Mechanistic analysis reveals that the hydroxyl and amino groups enriched on the surface of the pretreated HGMs serve as activation centers, facilitating the uniform enrichment of pyrrole monomers and promoting chain growth polymerization of the conjugated chain through nucleophilic and electrophilic interactions with the subamino groups in the pyrrole ring. Additionally, the reaction between the Lewis acid properties of PPy and the Lewis-type electron-donating amino groups in KH550 fosters strong bonding and the formation of a robust interface.
Exploring the Percolation Phenomena in Quantum Networks
Authors: Wang Chuanxin , Hu Xinqi , Dong Gaogao
Published: November 2024

Quantum entanglement as a non-local correlation between particles is critical to the transmission of quantum information in quantum networks (QNs); the key challenge lies in establishing long-distance entanglement transmission between distant targets. This issue aligns with percolation theory, and as a result, an entanglement distribution scheme called “Classical Entanglement Percolation” (CEP) has been proposed. While this scheme provides an effective framework, “Quantum Entanglement Percolation” (QEP) indicates a lower percolation threshold through quantum preprocessing strategies, which will modify the network topology. Meanwhile, an emerging statistical theory known as “Concurrence Percolation” reveals the unique advantages of quantum networks, enabling entanglement transmission under lower conditions. It fundamentally belongs to a different universality class from classical percolation. Although these studies have made significant theoretical advancements, most are based on an idealized pure state network model. In practical applications, quantum states are often affected by thermal noise, resulting in mixed states. When these mixed states meet specific conditions, they can be transformed into pure states through quantum operations and further converted into singlets with a certain probability, thereby facilitating entanglement percolation in mixed state networks. This finding greatly broadens the application prospects of quantum networks. This review offers a comprehensive overview of the fundamental theories of quantum percolation and the latest cutting-edge research developments.

Exercise-based cardiac rehabilitation (ExCR) programs are essential for patients diagnosed with cardiac diseases. Studies have shown that they aid in the rehabilitation process and may even facilitate a return to previous cardiorespiratory fitness. Also, patients who enroll and follow such programs have shown a lower rate of complications and mortality in the long run. The results vary depending on the type of program followed and the degree of debilitation the disease has caused. Therefore, in order to obtain optimal results, it is ideal to tailor each ExCR program to the individual profile of each patient. At the moment, the two most studied and employed training types are medium-intensity continuous training (MICT) and high-intensity interval training (HIIT). For most of the time, MICT was the first-choice program for patients with cardiovascular disease. In recent years, however, more and more studies have pointed towards the benefits of HIIT and how it better aids patients in recovering their cardiovascular fitness. Generally, MICT is more suited for patients with a severe degradation in functional capacity and who require a higher degree of safety (e.g., elderly, with a high number of comorbidities). On the other hand, while HIIT is more demanding, it appears to offer better outcomes. Therefore, this review aimed to summarize information from different publications on both types of training regimens in ExCR and assess their utility in current clinical practice.

The role of the human papillomavirus (HPV) in the establishment of cervical cancer has driven studies to find more effective methods of viral detection so that early intervention strategies can be performed. However, the methods still have limitations, especially regarding detecting the different genotypes simultaneously. We have developed a high-throughput system using a single-tube nested-multiplex polymerase chain reaction (NMPCR) for the detection of 40 HPV genotypes using capillary electrophoresis. The NMPCR assay was compared to the Hybrid Capture 2 assay (HC2) with 40 women from the Northeast of Brazil (São Luis, MA), a high endemic region, where the HPV positivity was 75% and 37.5%, respectively. These results were validated by performing a molecular epidemiological study on 5223 Brazilian women undergoing gynecological examinations from 2009 to 2017, who presented with an HPV prevalence of 59%. Multiple infections were found in 62.5% and 58% of the patients from the endemic region and from the Brazilian women population, respectively, mostly presenting high-risk genotypes (90.5% and 60%, respectively). Considering cervical intraepithelial neoplasia and adenocarcinomas, the sensitivity and specificity were 97.5% and 100%, respectively. The NMPCR assay was also capable of identifying viral subtypes in cases of multiple infections, even with low viral loads (10−6 ng/µL of HPV DNA). The NMPCR test is a promising and robust tool for HPV diagnostics and a screening tool for prevention of cervical cancer.

Atypical bacterial pathogens present the ability to induce pulmonary damage. At present, there are no available phenotypic diagnosis tests that achieve up to 100% reliability. Therefore, clinicians must utilise molecular techniques for the detection and identification of these pathogens. The main objective of this research was to evaluate the prevalence of atypical bacteria in paediatric patients from different age groups. A total of 609 clinical samples were collected from paediatric patients who presented with an adverse respiratory condition during the period from March 2021 to February 2024. DNA was extracted from the samples, and end-point PCR was performed to detect atypical bacteria. Statistical analyses were performed to evaluate the bacterial prevalence and assess clinical data from newborns and mothers that could be related to RDS. A total of 139 patients exhibited at least one atypical organism (22.82%). Ureaplasma parvum was more prevalent in neonates, while M. pneumoniae and C. pneumoniae were more prevalent in older infants. Atypical bacteria can be present in all seasons of the year, but their prevalence increases during hot weather. Mixed infections due to atypical bacteria may occur. The risk factors related to the development of RDS are prematurity, low weight, and orotracheal intubation.

Published: November 2024

Escherichia coli O157:H7, a Shiga-toxin-producing E. coli (STEC), is an important pathogen related to foodborne disease that is responsible for a growing number of outbreaks worldwide and has been detected in processed meats, dairy, and fresh vegetables. Although culturing is the gold standard method for detection of this bacterium, molecular methods based on nucleic acid amplification techniques such as PCR are becoming more common because of their rapidity, sensitivity, and specificity. However, to ensure reliable results among the several alternative PCR protocols (e.g., commercial kits and reference methods), different measurement assurance tools, including validated methods, reference materials, and proficiency tests, among others, are required. Herein, we present a digital PCR method validation for E. coli O157:H7 detection and quantification using seven specific gene sequences; this method quantified nucleic acids from different E. coli serotypes, with a detection range of 6.6 to 7900 copies/µL and a repeatability standard deviation over the concentration range of 1% to 13.6%. The relative standard uncertainty was 3.5–14.6%, and the detection limit was 0.27 copies/µL. Subsequently, two batches of a candidate reference material based on E. coli O157:H7 genomic DNA were then produced and characterized for evaluation of copy number concentration with the validated ddPCR method, with assigned values of 164,770 ± 9251 and 172 ± 9 copies/μL. Thus, this study demonstrated the development of a validated method and reference material for dPCR and qPCR detection of E. coli O157:H7, a key STEC responsible for food poisoning.

Authors: Koyama Tamami , Yamaguchi Takumi , Matsunari Yuko
Published: November 2024

Background/Objectives: To explore how Public Health Nurses (PHNs) in Fukushima perceived their roles and activities as necessary or inadequate from the immediate aftermath through the long-term recovery of the nuclear disaster. Methods: We conducted a qualitative study using a self-administered questionnaire with open-ended questions to capture the perceptions of PHNs across three disaster phases: peacetime; nuclear emergency; and recovery. Responses were analyzed through qualitative content analysis. Results: PHNs’ needs and perceived inadequacies varied across the disaster phases. In peacetime, the emphasis was on education for disaster preparedness for both nurses and residents. During the nuclear emergency, the focus shifted to the need for PHN deployment and radiation screening systems, highlighting a significant gap in radiation knowledge. In the recovery phase, the importance of ongoing resident support, rumor management, and trust-building was emphasized, alongside an increased need for radiation education. Conclusions: This study highlights the critical need for phase-specific support systems and educational programs to enhance PHNs’ disaster response capabilities. It underscores the importance of preparedness plans and continuous training to improve PHNs’ effectiveness in addressing public health challenges during nuclear disasters. This study was not registered.

Published: November 2024

Recent advances in microbiome research have uncovered a dynamic and complex connection between the gut and lungs, known as the gut–lung axis. This bidirectional communication network plays a critical role in modulating immune responses and maintaining respiratory health. Mediated by immune interactions, metabolic byproducts, and microbial communities in both organs, this axis demonstrates how gut-derived signals, such as metabolites and immune modulators, can reach the lung tissue via systemic circulation, influencing respiratory function and disease susceptibility. To explore the implications of this connection, we conducted a systematic review of studies published between 2001 and 2024 (with as much as nearly 60% covering the period 2020–2024), using keywords such as “gut–lung axis”, “microbiome”, “respiratory disease”, and “immune signaling”. Studies were selected based on their relevance to gut–lung communication mechanisms, the impact of dysbiosis, and the role of the gut microbiota in respiratory diseases. This review provides a comprehensive overview of the gut–lung microbiome axis, emphasizing its importance in regulating inflammatory and immune responses linked to respiratory health. Understanding this intricate pathway opens new avenues for microbiota-targeted therapeutic strategies, which could offer promising interventions for respiratory diseases like asthma, chronic obstructive pulmonary disease, and even infections. The insights gained through this research underscore the potential of the gut–lung axis as a novel target for preventative and therapeutic approaches in respiratory medicine, with implications for enhancing both gut and lung health.
Synergistic and Antagonistic Effects of Mixed-Leaf Litter Decomposition on Nutrient Cycling
Authors: Mukamparirwa Vestine , Maliondo Salim M. S. , Mugunga Canisius Patrick
Published: November 2024

Understanding decomposition patterns of mixed-leaf litter from agroforestry species is crucial, as leaf litter in ecosystems naturally occurs as mixtures rather than as separate individual species. We hypothesized that litter mixtures with larger trait divergence would lead to faster mass loss and more balanced nutrient release compared to single-species litter. Specifically, we expected mixtures containing nutrient-rich species to exhibit synergistic effects, resulting in faster decay rates and sustained nutrient release, while mixtures with nutrient-poor species would demonstrate antagonistic effects, slowing decomposition. We conducted a mesocosm experiment using a custom wooden setup filled with soil, and the litterbag method was used to test various leaf litter mixtures. The study involved leaf litter from six agroforestry tree species: three species from humid highland regions and three from semi-arid regions. Treatments included three single-species leaf litter mixtures, three two-species mixtures, and one three-species mixture, based on the sampling region. Species included Calliandra calothyrsus (Ca), Croton megalocarpus (Cr), Grevillea robusta (G), Alnus acuminata (A), Markhamia lutea (M), and Eucalyptus globulus (E). Decay rate constants (k) were estimated using non-linear least-squares regression and observed mass loss was compared to predicted values for mixed-species litter treatments to assess synergistic and antagonistic effects. A two-way linear mixed-effects model was employed to explain variation in mass loss. Results indicate positive non-additive effects for leaf litter mixtures including nutrient-rich species and negative non-additive effects for mixtures including nutrient-poor species. The mixture of Ca + Cr + G had positive non-additive or synergistic effects as it decomposed faster than its corresponding single-species litter. Leaf litters with higher lignin content, such as A + M + E and Ca + Cr + G, exhibited less lignin release compared to what would be expected based on individual litter types, demonstrating antagonistic effects. These findings highlight that both litter nutrient constituents and litter diversity play an important role in decomposition processes and therefore in the restoration of the degraded and nutrient-depleted soils of Rwanda.

This study aimed at investigating the chemical composition and a selected group of bioactivities of jatoba (Hymenaea courbaril L.) pod residue. An aqueous extract (deionized water; AE) and a hydroethanolic extract (ethanol: deionized water, 70:30 v/v; ETOH) were obtained via maceration. Ten phenolic compounds were characterized via LC-DAD-ESI/MSn: seven procyanidins, two quercetin derivatives and one taxifolin derivative, with dimers and trimers of procyanidins being the main components of both extracts. Total phenolic compound levels of 2.42 ± 0.06 and 11 ± 1 mg/g were found in AE and ETOH, respectively; however, only seven compounds were identified in ETOH. The jatoba pod residue extracts showed notable antioxidant activities: ETOH had greater antioxidant potential in the OxHLIA and DPPH assays (IC50 = 25.4 μg/mL and 0.71 μg/mL, respectively); however, EA demonstrated greater potential in the FRAP system (IC50 = 2001.0 µM TE/mg). Only AE showed antiproliferative potential, being effective against cell lines of gastric (GI50 = 35 ± 1 µg/mL) and breast (GI50 = 89 ± 4 µg/mL) adenocarcinomas. Likewise, only AE showed modest anti-inflammatory potential (IC50 = 225 ± 2 µg/mL) in mouse macrophages. Bacteriostatic effects against bacteria were exerted by both extracts. Enterococcus faecalis and Listeria monocytogenes (MICs = 2.5 mg/mL) were especially sensitive to the ETOH extract. Taken together, the results suggest potential for jatoba pod residue as a source of molecules with biological activities and with possible industrial applications.

Published: November 2024

Sect. Tuberculate Chang belongs to the genus Camellia, which is an endemic group in China and has high research value. However, the phenotypic patterns of this taxon are complex and diverse, and the phenotypic variation in key traits is still unclear. In this study, a total of 212 samples from 18 populations of sect. Tuberculate plants were studied for 30 phenotypic traits of flowers, fruits, and leaves using analysis of variance, correlation analysis, principal component analysis, and cluster analysis. The results showed the following. (1) The plants in sect. Tuberculate were rich in phenotypic trait variation and possessed rich phenotypic diversity. The differentiation of phenotypic traits mainly came from among populations, with leaves (66.804%) being the largest and flowers (53.476%) being the smallest. Qualitative traits (70.264%) were greater than quantitative traits (57.608%). (2) Correlation analyses showed close and complex relationships among the phenotypic traits of flowers, fruits, and leaves. (3) The cumulative contribution of the first 10 principal components was up to 73.49%, which screened out 12 major traits contributing to the phenotypic differences in plants of sect. Tuberculate. (4) Q-type analysis showed that they were classified into 18 taxa at a Euclidean distance of 7.5 and 11 taxa at a Euclidean distance of 10. The 18 populations were not fully clustered according to the geographic distance of the plants, and there was an overlap between some of the populations. In summary, the degree of variation in phenotypic traits among populations of sect. Tuberculate plants is high, which is affected by the climatic environment. The 12 major phenotypic traits screened can be used as the basis for the classification of sect. Tuberculate plants. There are trait overlaps among some populations, which may be affected by the stochastic influence of the geographic climate and gene flow. This study will provide important references for interspecific identification, classification system construction, genetic mechanism, germplasm resource conservation, and exploitation of plants in sect. Tuberculate.

Translation for Performance: Biblical Performance Criticism in Bible Translation
Authors: Mathews Jeanette
Published: November 2024

Biblical Scholars working with ancient texts are engaged in the daily task of Bible translation. A commitment to Biblical Performance Criticism (BPC) can be transformative in the task of translation. It is argued in this paper that responsible translation will work towards replicating the artistry of original transmitters of texts in order to draw out traces of the original orality embedded in the texts. Examples of performance-sensitive translations of texts predominantly from the Hebrew Bible are provided. This e-paper also demonstrates that translations that draw out performative elements contribute to interpretation, especially when such scripts are staged before audiences. Subsequent analysis of the performance including audience response contributes to such interpretation. Performance-sensitive translation and actual performance thus become tools for embodiment and the interpretation of biblical texts in our own time.

Published: November 2024

This study presents a location method for buried polyethylene (PE) pipelines based on the double-tree complex wavelet cross-correlation delay. Initially, the dual-tree complex wavelet transform (DTCWT) is applied to denoise the acquired signal, followed by extracting the delay time through the cross-correlation function to locate the buried pipeline. A simulation model is established to analyze the peak values of the time-domain signals in both asymmetric and symmetric sensor layouts using COMSOL, determining the relationship between the signal time differences and pipeline positions. Then, an experimental test system is set up, and experiments are carried out under the conditions of asymmetric and symmetrical sensors and different excitation points. The results indicate that the maximum error is 4.6% for asymmetric arrangements and less than 1% for symmetric arrangements. In practical applications, the pipeline’s position can be inferred from the delay time, with higher accuracy observed as the excitation point approaches the sensor. This method addresses the limitations of existing pipeline locating techniques and provides a foundation for the development of pipeline positioning technology.

Numerical Investigation of the Nonlinear Drill String Dynamics Under Stick–Slip Vibration
Authors: Moharrami Mohammad Javad , Shiri Hodjat , Martins Clóvis de Arruda
Published: November 2024

This paper presents a comprehensive analysis of the influence of rotary table velocity, weight-on-bit, and viscous damping on the drill string stick–slip vibration. The analysis allows for studying the qualitative and quantitative variation of the dynamic response of the drill pipes and drill collars/bit. To achieve this goal, a robust and practical finite element (FE) model of the full-scaled drill string was developed based on a velocity-weakening formulation of the nonlinear bit–rock interaction. A detailed investigation of damping parameters was carried out. The performance of the developed model was verified through comparisons with a lumped-parameter model and a field test example. Parametric studies on the stick–slip response of the entire drill string under different field operational conditions were conducted. The dynamical time series of the system response were analyzed in terms of the phase planes, response spectra, and descriptive statistics of the drill pipes and drill collars. The findings of the study revealed that for a realistic drill string geometry, the angular velocity (i.e., mean, peak-to-peak amplitude, and standard deviation) and dominant frequency of self-excited torsional stick–slip oscillations along the drill pipes and drill collars/bit are mainly governed by the rotary table velocity. Furthermore, it was shown that the contribution of higher harmonics in the torsional stick–slip response of the drill pipes is more substantial than the drill collars/bit.

Published: November 2024

Business model innovation is crucial for enhancing company performance. This study aims to investigate the relationship between the six dimensions of sustainable business model innovation and company performance among Chinese electric vehicle brands. A structural equation model is constructed based on a comprehensive literature review and hypothesis development. Using PLS-SEM, this study empirically analyzes questionnaire data collected from the top 12 electric vehicle brands in China to explore the relationship between these six core dimensions and company performance. The results indicate that innovation in “value proposition to customers”, value creation, value delivery, and “value of residual” have a significantly positive impact on the performance of Chinese electric vehicle brands. However, value capture innovation and “value of after-sales service” innovation were not found to be statistically significant. This paper provides an in-depth analysis of the mechanism through which sustainable business model innovation impacts company performance, enriching the theoretical foundation of academic research in this field and broadening its practical applications in management.

The study of various pathological conditions associated with COVID-19 remains an ur gent task. One of the most significant complications of the novel coronavirus infection is damage to the cardiovascular system. According to various authors, acute myocardial injury associated with COVID-19 develops from 12% to 28-30% of cases. The most important distinctive feature of SARS-Cov-2 infection is its ability to induce prolonged and decompensated myocarditis. Medical workers are a group at increased risk of infection with the SARS-CoV-2 when provid ing medical care in modern conditions. The novel coronavirus infection in medical workers can be considered an occupational disease if the infection occurred while they were perform ing their professional duties. The presence of severe complications of the novel coronavirus infection, leading to disabili ty, gives relevance to the analysis of the characteristics of occupational diseases of medical workers in order to improve their diagnosis, prevention, treatment, and rehabilitation. In the Samara Region in 2021-2022, 10 cases of chronic occupational diseases associat ed with the novel coronavirus infection that caused permanent disability were identified in medical workers. Of these, viral myocarditis was diagnosed in four cases, and inflammatory dilated cardiomyopathy – in one case. The article presents 2 clinical observations of the development of myocarditis and inflammato ry dilated cardiomyopathy with congestive heart failure associated with the novel coronavirus infection in medical workers, as well as principles and results of a medical examination con ducted in order to establish a causal relationship between the disease and professional activity. The need for a multidisciplinary approach to the diagnosis of manifestations and treatment of COVID-19 and its complications, with the mandatory participation of a cardiologist, improvement of the assessment of causal relationship between COVID 19 and occupation and admission to work in conditions of high risk of SARS-CoV-2 infection of medical workers is emphasized.

Production optimization processes and staff cuts can trigger the emergence of mobbing in organizations of various branches of industry and national economy, scientific and educational groups, and various forms of ownership. Meanwhile, prevention and minimization of the negative consequences of mobbing in any group represent a complex medical and social task that requires not only psychological support, consultations with doctors and specialists in corporate management and psychology

DECISION MAKING IN EPILEPTIC AVMS
Authors: Balasa Adrian
Published: November 2024

While there is no doubt about the need for surgical treatment of a ruptured arteriovenous malformation (AVM), the decision to surgically treat a patient presenting solely with seizures is more controversial.
 
Arteriovenous malformations (AVMs) arise from an abnormal connection between high-flow arterial vessels and low-flow venous vessels, resulting in a dysplastic vascular nidus within the brain tissue. The inherent flow irregularities within AVMs make them prone to rupture, which occurs in approximately half of patients. Additionally, seizures represent the second most common clinical manifestation of AVMs, presenting in 20%–45% of individuals with these lesions.
 
This paper investigates the angiographic and MRI features of arteriovenous malformations that present with epilepsy, and discusses the surgical considerations in managing these patients and integration of multimodal approach focusing on the standard microsurgical techniques utilized.
 
Patients presenting with seizures as the primary symptom of an arteriovenous malformation carry a higher surgical risk compared to those presenting with haemorrhage.
 
Several factors have been associated with an increased risk of seizures in patients with arteriovenous malformations (AVMs). These include male gender, younger patient age, AVMs located in the frontal or temporal lobes, AVMs situated in the brain cortex, superficial venous drainage, a superficial temporal lobe AVM nidus, fistulous AVMs, and AVMs with venous stenosis.
 
Surgical treatment is the recommended approach for patients with Spetzler-Martin grade I–III arteriovenous malformations. Resecting an unruptured brain arteriovenous malformation in a patient presenting only with epilepsy is a complex decision that requires a thorough understanding of the lesion’s anatomy, the patient’s history, and the neurosurgeon’s skills.
A SPINAL TRAUMA, A TUMOR AND EVERYTHING IN BETWEEN

Introduction
Burkitt lymphoma is a male predominant (3:1 male:female ratio) aggressive B-cell non-Hodgkin lymphoma that can present as a sporadic variant with meningeal involvement in about 20% of cases. Therefore, it can manifest with neurologic deficits due to compression of the spinal cord or spine nerve root.
 
Case Report
We report the case of a 6 years-old girl who presented in the emergency department following a traumatic vertebral injury (fall from around 1.5 meters) with no spinal cord involvement. She accused upper back pain, walking and orthostatism difficulties and manifested a light to moderate inferior paraparesis (MCR 3/5) The MRI revealed a space-occupying epidural mass between T1-T4, severely compressing the spinal cord initially thought to be an epidural hematoma. Emergency surgery was performed with duro-radicular decompression and mass excision through a T1-T4 laminotomy followed by a laminoplasty. The unveiled mass was white, minimally vascularized and adherent to the dura raising the suspicion of a tumor. Postoperatively the patient exhibited significant neurological improvement with resolution of the paraparesis and normal gait restoration.
 
Three weeks later, the patient returned with complaints of abnormal gait, lumbar pain radiating in the right lower leg and upon examination a light right lower limb monoparesis (MRC 4/5) following another traumatic event. Emergency MRI of the whole spine with contrast was requested just as the pathologist in charge of the case suggested a diagnosis of Burkitt lymphoma, prompting a whole-body MRI. A severe recurrence was noted at the site of the previous lesion along with a new lumbar lesion, and several intraabdominal, intrathoracic, ovarian tumor sites with diffuse infiltration of the bone marrow. The patient was urgently referred to the pediatric oncology department and started on steroidal anti-inflammatory treatment and chemotherapy.
 
Conclusions
Burkitt lymphoma involving the nervous system in children requires increased medical attention during the clinical, histopathological examination and treatment phase, due to the association with advanced disease and, although rare, should be considered as a differential diagnosis in pediatric patients with epidural lesions. The management of such lesions demands a solid collaboration between neurosurgeon, pediatrician, pathologist and oncologist for an early diagnosis and proper treatment.

Introduction
Multiple synchronous intracranial lesions present a significant diagnostic and therapeutic challenge, in most cases appearing as metastatic tumors or same-cell type tumors.
 
Case Report
We report the case of a 73-year-old patient admitted in our department with light left hemiparesis (MRC MMT 4/5), light left hypoesthesia and transitory and remitted state of temporo-spatial confusion that debuted around six weeks prior to presentation. The neurological exam confirmed the sensorimotor deficit and displayed the existence of left neglect syndrome. The patient’s MRI revealed a giant temporo-parieto-occipital mass almost 7 cm in diameter that appeared to have an intraventricular starting point and showed a relatively homogeneous contrast enhancement with significant mass effect. A concomitant superficial parieto-temporal lesion was also noted. Both lesions were excised in a successive manner from superficial to deep, using a right parieto-temporal craniotomy. While the giant mass had a yellowish color and an extremely hard consistency, the superficial one was easily suctionable and had a grey-reddish color and was extremely well vascularized, raising the suspicion of concomitant brain lesions of different histology. Postoperatively the patient underwent a routine thoracic CT scan in the context of a position related soft tissue injury that revealed the existence of two pulmonary lesions, further deepening our suspicion of concomitant brain lesions of different histology.
 
Conclusions
Although extremely rare, the appearance of two histologically distinct brain lesions in patients with no evidence of a genetic condition should be taken into consideration especially in the context of intraoperative differences in order to successfully guide the patients’ follow-up treatment.
