Published: September 2024

Jingmen tick virus (JMTV) is a recently discovered segmented RNA virus, closely related to flaviviruses. It was identified for the first time in 2014, in China and subsequently in Brazil. Following this discovery, JMTV-related sequences have been identified in arthropods, vertebrates (including humans), plants, fungus, and environmental samples from Asia, America, Africa, Europe, and Oceania. Several studies suggest an association between these segmented flavi-like viruses, termed jingmenviruses, and febrile illness in humans. The development of rapid diagnostic assays for these viruses is therefore crucial to be prepared for a potential epidemic, for the early detection of these viruses via vector surveillance or hospital diagnosis. In this study, we designed a RT-qPCR assay to detect tick-associated jingmenviruses, validated it and tested its range and limit of detection with six tick-associated jingmenviruses using in vitro transcripts. Then, we screened ticks collected in Corsica (France) from different livestock species, in order to determine the distribution of these viruses on the island. In total, 6269 ticks from eight species were collected from 763 cattle, 538 horses, 106 sheep, and 218 wild boars and grouped in 1715 pools. We report the first detection of JMTV in Corsica, in Rhipicephalus bursa, Hyalomma marginatum and R. sanguineus ticks collected from cattle and sheep. The highest prevalence was found in the Rhipicephalus genus. The complete genome of a Corsican JMTV was obtained from a pool of Rhipicephalus bursa ticks and shares between 94.7% and 95.1% nucleotide identity with a JMTV sequence corresponding to a human patient in Kosovo and groups phylogenetically with European JMTV strains. These results show that a Mediterranean island such as Corsica could act as a sentinel zone for future epidemics.
Aspartyl proteases target host actin nucleator complex protein to limit epithelial innate immunity
Authors: Patra Sandip , Kaur Rupinder
Published: September 2024

Epithelial-immune cell communication is pivotal to control microbial infections. We show that glycosylphosphatidylinositol-linked aspartyl proteases (Yapsins) of the human opportunistic pathogenic yeast Candida glabrata (Cg) thwart epithelial cell (EC)-neutrophil signalling by targeting the EC protein, Arpc1B (actin nucleator Arp2/3 complex subunit), which leads to actin disassembly and impeded IL-8 secretion by ECs. Further, the diminished IL-8 secretion inhibits neutrophil migration, and protects Cg from the neutrophil-mediated killing. CgYapsin-dependent Arpc1B degradation requires Arginine-142 in Arpc1B, and leads to reduced Arpc1B-p38 MAPK interaction and downregulated p38 signalling. Consistently, Arpc1B or p38 deletion promotes survival of the Cg aspartyl protease-deficient mutant in ECs. Importantly, kidneys of the protease-deficient mutant-infected mice display elevated immune cell infiltration and cytokine secretion, implicating CgYapsins in immune response suppression in vivo. Besides delineating Cg-EC interplay, our results uncover a novel target, Arpc1B, that pathogens attack to constrain the host signalling networks, and link Arpc1B mechanistically with p38 activation.

Published: September 2024

The epigenome harbors diverse sets of DNA elements that can be revealed with distinct sequencing technologies. Epigenomic sequencing studies identify chromatin states to partition the genome into DNA elements and find alterations between healthy and disease settings, known as chromatin variants, to identify the genetic basis of disease. These disease-associated chromatin variants serve as biomarkers and define vulnerabilities for epigenetic therapy. Epigenomic sequencing technologies are constantly evolving and their adoption for clinical uptake should be considered to improve therapeutic applicability.

Information hiding using approximate POSIT representation
Authors: Abed Sa'ed , Aldamkhi Ghadeer , Ahmad Imtiaz
Published: September 2024

POSIT is a numerical system consists of sign, regime, exponential, and fraction bits to overcome some limitations of the IEEE‐754 floating point (FP) representation. This work proposes a technique to hide critical information in the least significant bits (LSBs) of the POSIT FP representation by exploiting approximate computing (AC). The proposed technique, called information hiding using POSIT and LSB (IHUPL), explores the opportunities offered by both the POSIT representation and the AC to hide information with a minimum loss in accuracy and other performance metrics. IHUPL offers two options for hiding information: either by embedding one digit of each character into each pixel or by embedding all the digits of the character at the same time into each pixel of the alpha‐red, green, blue, or black/white image. Experimental results are evaluated for benchmark images and showed that IHUPL enhanced the accuracy of embedding data into LSB of POSIT FP by an average of 5%, the image quality improvement rates of IHUPL are 19% and 16% for options 1 and 2, respectively. Besides the encoding method using IHUPL, the paper outlines an extraction decoding technique that saves the original replacement bits in a key‐image to recover the hidden security message.

The impact of sea level rise on the compound submergence of coastal cities- a case study of Haidian Island
Authors: Cheng Guangchen
Published: September 2024

Coastal cities often have advanced drainage systems connected to the sea, reducing the risk of flooding. In recent years, with climate change, global sea levels have been rising. In 2023, the sea level in the South China Sea rose by 52 mm compared to the long-term average. This study uses a coupled system of a two-dimensional hydrodynamic model and a one-dimensional drainage pipe network model to investigate the impact of rising sea levels on compound flooding in coastal cities under future climate change scenarios. The results indicate that rising sea levels increase the baseline water level of storm surges, significantly increasing the risk of flooding in cities.
Study on the Effect of Nano Pour Point Depressant on Wax Oil Crystallization
Authors: Li Qifu , Mo Linlin , Yan Feng , Nie Chaofei
Published: September 2024

The influence of nano pour point depressant (NPPD) on crude oil containing wax is primarily manifested through their interaction with the wax constituents. This study examines the depressant's effects using a polarizing microscope and an atomic force microscope (AFM) to assess morphological and structural changes in the wax crystals within the oil, both before and after the addtion of the NPPD. Additionally, a surface tensiometer measured surface tension, while a rheometer evaluated viscosity and modulus alterations. These methods facilitated insights into NPPD's mechanistic effects. The interaction process between crude oil wax crystal molecules and the main components of NPPD was simulated using JOCTA molecular dynamics simulation software, and the highest interaction strength between benzenesulfonic acid groups and crude oil wax crystal molecules was determined. The findings indicate that the addition of the NPPD alters the growth patterns and crystalline structure of the wax in the oil. Initially, the wax crystals present as flaky, predominantly single molecular layer lamellae with a thickness of approximately 100 nm. Post-treatment, the wax crystals adopt a flattened lamellar configuration, composed of multilayer lamellae, with a reduced thickness of within 10 nm and exhibiting short-range order. AFM height maps reveal an increase in the average roughness of the wax oil correlated with the addition of the NPPD across different sampling lengths. Surface tension measurements demonstrate that the wax oil doped with the NPPD exhibits lower surface tension than undoped oil, with the surface tension decreasing as the temperature increases.

Published: September 2024

To investigate the influence of rotational speed and drilling pressure on the milling efficiency of flat-bottomed milling shoes, a three-dimensional milling model of flat-bottomed milling shoes and deformed casing was established by using ABAQUS finite element software, and the optimal parameter combinations of milling efficiency were investigated at rotational speeds of 70~90r/min and drilling pressures of 5~25kN. The results show that: with the increase of drilling pressure and rotational speed, the mass loss of casing and the amount of footage of the grinding shoe increase, and the grinding and milling efficiency is optimal under the process parameters of rotational speed of 90r/min and drilling pressure of 15kN. This paper provides an analytical method for the subsequent optimization and improvement of the evaluation of the pipe repair process and promotes the technological development of the research on the casing change mechanism and prevention and control countermeasures in shale gas wells.

Authors: Liu Qi
Published: September 2024

A reliable sealing structure is the key to achieving reverse circulation drilling technology for large- diameter reverse circulation down the hole hammers, and it is also a difficult point in the design of large- diameter reverse circulation down the hole hammers. The existing large-diameter reverse circulation down the hole hammers are designed based on the sealing structure of the bottom drilling tool body. This article proposes a joint sealing method for hole bottom and hole opening. Based on this sealing method, a bundle type reverse circulation down the hole hammer and hole opening sealing device with a diameter of 710/311mm were developed for hole expansion, and field tests were conducted with a double wall drilling tool with a diameter of 127/70mm. The method achieved good continuous reverse circulation slag removal effect, with an average mechanical drilling speed of 2.1m/h, which is 2.6 times higher than the conventional roller bit hole expansion method. The experimental results indicate that the joint sealing method between the bottom and the mouth of the hole is feasible and worthy of further promotion and application.

These intermittent energies require resources to rebalance the grid. We are using a method developed for the German energy transition (Energiewende) to work out the orders of magnitude.

With regard to the mix adopted for France, a quarter of intermittent production, 44 TWh, should be transferred between periods of surplus and shortage. This would be possible with large-scale storage - 15 TWh in volume and 45 GW in power - which unfortunately far exceeds known resources (hydroelectric dams, batteries, etc.). Without such storage, fossil fuel power stations would be used to meet demand, thereby worsening the carbon footprint. This can already be seen in the results of the past decade in Germany and Europe.

Published: September 2024

Background and study aims Rectal mucosal prolapse syndrome (RMPS) usually manifests as rectal bleeding and tenesmus. Endoscopically it can be easily misdiagnosed as malignant rectal tumor (MRT). This study aimed to investigate factors to distinguish RMPS and MRT and to explore endoscopic features of RMPS.

Patients and methods Data from patients endoscopically diagnosed with rectal lesions, masses, or tumors, were retrospectively collected. Clinical information, endoscopic images, and histologic reports were reviewed. Patients endoscopically and histologically diagnosed with RMPS were included for phenotype classification.

Results 826 patients were enrolled, among them 755 (91.4%), 22 (2.7%), 10 (1.2%), and 39 (4.7%) were respectively diagnosed with MRT, RMPS, endometriosis, and neuroendocrine tumors. Compared with MRT, patients with RMPS were significantly younger (33.5 vs. 62, P < 0.001) and lesions were significantly smaller (2 cm vs. 3 cm, P = 0.007). Moreover, the clinical course of patients with RMPS was significantly longer than for those with MRT (12 months vs. 3 months, P < 0.001). Morphologically, we classified lesions of RMPS into five phenotypes, that is, lesions with circumferential stenosis (19.4%), protrusions (41.7%), both ulcers and protrusions (11.1%), ulcers (11.1%), and flat manifestations (16.7%). Protruding lesions were more frequently observed in females (P = 0.039), whereas ulcerative lesions were found involving a smaller proportion of the rectal circumference (P = 0.028). Lesions with only ulcers were found with a shorter distance compared with those with only protrusions (5 cm vs. 10 cm, P = 0.034).

Conclusions Age, clinical course, and size of the lesion can be applied to distinguish MRT and RMPS. Five phenotypes have been identified and features of ulcers/protrusions should be further explored.

Background and study aims Endoscopic ultrasound (EUS) is vital for early pancreatic cancer diagnosis. Advances in artificial intelligence (AI), especially deep learning, have improved medical image analysis. We developed and validated the Modified Faster R-CNN (M-F-RCNN), an AI algorithm using EUS images to assist in diagnosing pancreatic cancer.

Methods We collected EUS images from 155 patients across three endoscopy centers from July 2022 to July 2023. M-F-RCNN development involved enhancing feature information through data preprocessing and utilizing an improved Faster R-CNN model to identify cancerous regions. Its diagnostic capabilities were validated against an external set of 1,000 EUS images. In addition, five EUS doctors participated in a study comparing the M-F-RCNN model's performance with that of human experts, assessing diagnostic skill improvements with AI assistance.

Results Internally, the M-F-RCNN model surpassed traditional algorithms with an average precision of 97.35%, accuracy of 96.49%, and recall rate of 5.44%. In external validation, its sensitivity, specificity, and accuracy were 91.7%, 91.5%, and 91.6%, respectively, outperforming non-expert physicians. The model also significantly enhanced the diagnostic skills of doctors.

Conclusions: The M-F-RCNN model shows exceptional performance in diagnosing pancreatic cancer via EUS images, greatly improving diagnostic accuracy and efficiency, thus enhancing physician proficiency and reducing diagnostic errors.
Communication Challenges Experienced by Clinicians and Patients during Teleconsultation: A Scoping Review
Authors: Sota Takashi , Jackson Tim , Yang Eleanor , Lau Annie Y.S.
Published: September 2024

Background As teleconsultations continue to rise in popularity due to their convenience and accessibility, it is crucial to identify and address the challenges they present in order to improve the patient experience, enhance outcomes, and ensure the quality of care. To identify communication challenges that clinicians and patients experience during teleconsultation, a scoping review was conducted.

Objective This study aimed to identify communication challenges that clinicians and patients experience during teleconsultation.

Methods Studies were obtained from four databases (Ovid [MEDLINE], Ovid [Embase], CINAHL, and Scopus). Gray literatures were not included. Studies focused on communication challenges between clinicians and their patients during teleconsultation in the context of coronavirus disease 2019 (COVID-19) and published from January 2000 to December 2022, were collected. The screening process was conducted by two independent reviewers. Data extraction was performed using a standardized form to capture study characteristics and communication challenges. Extracted data were analyzed to identify the communication challenges during teleconsultation, adherent to Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Review (PRISMA-ScR).

Results A total of 893 studies were collected from four databases and 26 studies were selected based on inclusion/exclusion criteria. Of these 26 eligible studies, 12 (46%) were from the United States, 3 studies (12%) were from Australia, and 2 (8%) were from the United Kingdom and Canada. These studies included 12 (46%) qualitative studies, 6 (23%) quantitative studies, 6 (23%) review articles, and 2 (8%) case reports. Eight factors contributing to communication challenges between clinicians and patients during teleconsultations were identified: technical issues, difficulties in developing rapport, lack of non-verbal communication, lack of physical examination, language barrier, spatial issues, clinician preparation, and difficulties in assessing patients' health literacy.

Conclusion Eight factors were identified as contributing to communication challenges during teleconsultation in the context of COVID-19. These findings highlight the need to address communication challenges to ensure effective teleconsultations. With the rise of teleconsultation in routine health care delivery, further research is warranted to confirm these findings and to explore ways to overcome communication challenges during teleconsultation.
Modified Miniskirt Bentall with an Annular Pericardial Patch for Bentall's Endocarditis
Authors: Morisaki Akimasa , Takahashi Yosuke , Nishiya Kenta , Shibata Toshihiko
Published: September 2024

Surgery for Bentall's endocarditis poses challenges because the infection spreads to the aortic valve annulus, leading to an annular abscess that necessitates reconstruction. We present a straightforward miniskirt Bentall procedure using an annular pericardial patch to treat Bentall's endocarditis with an annular abscess. After removing the former composite graft and debriding the aortic root and annulus, we created a miniskirt-composite graft using a mechanical or bioprosthetic valve, a straight or Valsalva graft, and an annular bovine pericardial patch with a valve prosthetic sizer. The miniskirt-composite graft, along with the underlying annular pericardial patch, was implanted using a double-layered suture technique.

Published: September 2024

Granulomatous mastitis (GM) is a benign granulomatous condition, and its pathogenesis may be related to autoimmune disorders. Cellular immunity, humoral immunity, immunoglobulins, and complement could all play a role in the disease process, showing certain clinical patterns. Corticosteroids can quickly control disease progression, and immunosuppressants can be used for complex and refractory GM cases. In traditional Chinese medicine (TCM), “healthy qi” is similar to immune system function. For GM with deficient healthy qi, TCM treatments such as internal and external herbal applications can help regulate immune function and shorten disease duration by staged and TCM treatment, regulating viscera, reinforcing healthy qi, and eliminating pathogenic factors.
Altered Mental Status and Delirium in Pediatric Patients

Published: September 2024

Mental status is the collection of an individual's consciousness, perception, emotion, memory, and cognition at a particular point in time, which is inferred by the clinician through careful observation and interaction. The pediatric mental status assessment must be approached with an understanding of cognitive, language, and psychosocial development. Alterations must then be comprehensively and clearly described. Delirium is a phenotypic diagnosis with a specific set of criteria in the DSM and is a serious neurocognitive disorder caused by physiologic changes due to illness, injury, toxins, medications, and/or substances. Recognition of delirium in children is improved by monitoring of predisposing risks and precipitating factors, as well as the regular use of validated pediatric screening tools. Management of delirium is focused on treatment of the underlying etiology, prevention of iatrogenic deliriogenic factors, and patient safety.
