Published: May 2024

AbstractThe Internet of Things (IoT) devices spawn growing diverse social platforms and online data at the network edge, propelling the development of cross-platform applications. To integrate cross-platform data, user identity linkage is envisioned as a promising technique by detecting whether different accounts from multiple social networks belong to the same identity. The profile and social relationship information of IoT users may be inconsistent, which deteriorates the reliability of the effectiveness of identity linkage. To this end, we propose a topic and knowledge-enhanced model for edge-enabled IoT user identity linkage across social networks, named TKM, which conducts feature representation of user generated contents from both post-level and account-level for identity linkage. Specifically, a topic-enhanced method is designed to extract features at the post-level. Meanwhile, we develop an external knowledge-based Siamese neural network for user-generated content alignment at the account-level. Finally, we show the superiority of TKM over existing methods on two real-world datasets. The results demonstrate the improvement in prediction and retrieval performance achieved by utilizing both post-level and account-level representation for identity linkage across social networks.

Abstract
Background
Currently, different guidelines recommend using different methods to determine whether deduplication is necessary when determining the detection rates of multidrug-resistant organisms (MDROs). However, few studies have investigated the effect of deduplication on MDRO monitoring data. In this study, we aimed to investigate the influence of deduplication on the detection rates of MDROs in different specimens to assess its impact on infection surveillance outcomes.

Methods
Samples were collected from hospitalized patients admitted between January 2022 and December 2022; four types of specimens were collected from key monitored MDROs, including sputum samples, urine samples, blood samples, and bronchoalveolar lavage fluid (BALF) samples. In this study, we compared and analysed the detection rates of carbapenem-resistant Klebsiella pneumoniae (CRKP), carbapenem-resistant Escherichia coli (CRECO), carbapenem-resistant Acinetobacter baumannii (CRAB), carbapenem-resistant Pseudomonas aeruginosa (CRPA), and methicillin-resistant Staphylococcus aureus (MRSA) under two conditions: with and without deduplication.

Results
When all specimens were included, the detection rates of CRKP, CRAB, CRPA, and MRSA without deduplication (33.52%, 77.24%, 44.56%, and 56.58%, respectively) were significantly greater than those with deduplication (24.78%, 66.25%, 36.24%, and 50.83%, respectively) (all P < 0.05). The detection rates in sputum samples were significantly different between samples without duplication (28.39%, 76.19%, 46.95%, and 70.43%) and those with deduplication (19.99%, 63.00%, 38.05%, and 64.50%) (all P < 0.05). When deduplication was not performed, the rate of detection of CRKP in urine samples reached 30.05%, surpassing the rate observed with deduplication (21.56%) (P < 0.05). In BALF specimens, the detection rates of CRKP and CRPA without deduplication (39.78% and 53.23%, respectively) were greater than those with deduplication (31.62% and 42.20%, respectively) (P < 0.05). In blood samples, deduplication did not have a significant impact on the detection rates of MDROs.

Conclusion
Deduplication had a significant effect on the detection rates of MDROs in sputum, urine, and BALF samples. Based on these data, we call for the Infection Prevention and Control Organization to align its analysis rules with those of the Bacterial Resistance Surveillance Organization when monitoring MDRO detection rates.

AbstractRecently, focus has been placed on renewable sources, as they can be provided in large quantities at the lowest possible cost, in order to create nanoparticles. One of these sources is Zygnema moss which used in the present investigation to create Copper oxide nanoparticles (CuONPs). Several phenols and flavonoids were identified the extract of Zygnema sp. via analysis of High performance liquid chromatography. These constituents served as reducing and stabilizing agents for CuONPs. Characterization of CuONPs was performed via UV-visible spectrum that demonstrated peak at 252 nm, Transmission electron microscopy that showed spherical CuONPs with mean diameter of 30.06 nm, Fourier transform infrared spectroscopy that confirm that presence of several functional groups aided to formation of CuONPs. The crystallographic pattern of CuONPs was recorded via X-ray diffraction analysis. Antimicrobial potential of CuONPs was compared to copper acetate and antibiotic/antifungal drug. CuONPs exhibited more inhibition zones against S. aureus (32 ± 0.1 mm), E. coli (36 ± 0.1 mm), S. typhi (27 ± 0.2 mm), E. faecalis (37 ± 0.1 mm), C. albicans (34 ± 0.3 mm) than copper acetate and antibiotic/antifungal drug. Promising MIC values of were recorded against S. aureus, E. coli, and S. typhi. CuONPs at 200 ppm inhibited the growth of C. lunata, F. oxysporium, A. flavus, and Mucor circinelloid with inhibtion of 76.92, 73.33, 63.63, and 53.84%, respectively regarded the control 100% growth. The photocatalytic role of CuONPs was recorded for degradation of reactive red (RR195) and reactive blue (RB) dyes with maximum degradation of 84.66% and 90.82%, respectively at 75 min. Moreover, the optimal dyes degradation was 84.66 and 90.82%, respectively at 40 °C.

Abstract
Backgrounds and objectives
The present study was designed to define a novel algorithm capable of predicting female adolescents’ cervical vertebrae maturation stage with high recall and accuracy.

Methods
A total of 560 female cephalograms were collected, and cephalograms with unclear vertebral shapes and deformed scales were removed. 480 films from female adolescents (mean age: 11.5 years; age range: 6–19 years) were used for the model development phase, and 80 subjects were randomly and stratified allocated to the validation cohort to further assess the model’s performance. Derived significant predictive parameters from 15 anatomic points and 25 quantitative parameters of the second to fourth cervical vertebrae (C2-C4) to establish the ordinary logistic regression model. Evaluation metrics including precision, recall, and F1 score are employed to assess the efficacy of the models in each identified cervical vertebrae maturation stage (iCS). In cases of confusion and mispredictions, the model underwent modification to improve consistency.

Results
Four significant parameters, including chronological age, the ratio of D3 to AH3 (D3:AH3), anterosuperior angle of C4 (@4), and distance between C3lp and C4up (C3lp-C4up) were administered into the ordinary regression model. The primary predicting model that implements the novel algorithm was built and the performance evaluation with all stages of 93.96% for accuracy, 93.98% for precision, 93.98% for recall, and 93.95% for F1-score were obtained. Despite the hybrid logistic-based model achieving high accuracy, the unsatisfactory performance of stage estimation was noticed for iCS3 in the primary cohort (89.17%) and validation cohort (85.00%). Through bivariate logistic regression analysis, the posterior height of C4 (PH4) was further selected in the iCS3 to establish a corrected model, thus the evaluation metrics were upgraded to 95.83% and 90.00%, respectively.

Conclusions
An unbiased and objective assessment of the cervical vertebrae maturation (CVM) method can function as a decision-support tool, assisting in the evaluation of the optimal timing for treatment in growing adults. Our novel proposed logistic model yielded individual formulas for each specific CVM stage and attained exceptional performance, indicating the capability to function as a benchmark for maturity evaluation in clinical craniofacial orthopedics for Chinese female adolescents.

AbstractThe design of well spacing significantly influences the sustainability and economic benefit of geothermal energy extraction. However, most studies have predominantly employed heat production-related parameters as indicators of well spacing, and a comprehensive analysis of well spacing design based on an economic model is necessary for practical implementation. In this study, an economic indicator considering the benefits derived from heat production and operating costs is proposed and applied in the Caofeidian, a typical abandoned oilfield in the Bohai Bay Basin. It offers a refined portrayal of directional wells, moving beyond rudimentary representations, to capture their appropriate degree of complexity and behavior in drilling configurations. First, by integrating thermophysical information and site investigation data from previous oil investigations, a heterogeneous 3D model is constructed to forecast the 30-year temperature and pressure evolution. Then, a modified levelized cost of heat (LCOH-HT) is proposed to perform economic analysis in optimizing the well spacing, revealing an optimal range of 300–600 m for the different selected wells. In comparison with results derived solely from heat production considerations, drilling and pumping costs contribute to a 300 m reduction in the optimal well spacing based on the proposed approach, as a larger well spacing leads to increased hydraulic losses and drilling cost, necessitating greater pumping efforts and costs. This finding underscores the need to balance economic and thermal considerations. In addition, we found the difference in the optimal well spacing in space is also caused by the porosity variations. Porosity affects fluid temperature and pressure, leading to changes in the benefits and costs associated with pressure fluctuations. Notably, this novel economic analysis method is not limited to spacing optimization; it can also be used to optimize operating parameters, such as the flow rate, which could provide practical strategies for geothermal energy extraction.

Abstract
Background
Interval appendectomy is widely recommended for patients with abscesses due to perforated appendicitis. A concomitant malignancy-related problem was reported after conservative treatment of acute appendicitis with abscess, but perforated appendicitis-associated tuberculous peritonitis was never reported.

Case presentation
A 67-year-old male patient with a laryngeal cancer history presented to our hospital with an acute appendicitis-associated ileal abscess. He was scheduled for an interval appendectomy after conservative treatment. Fortunately, the symptoms subsided, and the patient was discharged for a later scheduled appendectomy. However, after 3 months, he was readmitted to our hospital with fever and abdominal pain, and emergency surgery was performed, which was suspected to be peritonitis. Intraoperative results revealed numerous white nodules in the abdominal cavity. The condition was diagnosed as tuberculous peritonitis based on macroscopic results, later pathological findings, and positive T-SPOT.TB. The antituberculosis medications were effective, and the patient recovered and was discharged from the hospital 8 days thereafter.

Conclusion
Patients, particularly those immunocompromised, may develop tuberculous peritonitis after conservative treatment for acute perforated appendicitis.

Published: May 2024

Abstract
Background
Children and adolescents have the right to participate in decisions concerning their health and express their views, also regarding hospital experiences. Patient-reported experience measures (PREMs) are valuable tools for systematically incorporating patient voices into healthcare systems. New developments have focused on PREMs for children and adolescents, though they are more commonly used in adults. A recent systematic review mapping their use for children and adolescents indicates a growing interest in this area. However, most PREMs are completed by proxy, in this case parents, so they do not necessarily reflect children’s experiences or align with their rights. Innovation is required to support and engage children and adolescents in responding to these types of questionnaires.

Methods
Collaborating with children and adolescents (4–17 years), the primary aim of this study is to develop and validate the tool MyHospitalVoice containing digital and developmentally appropriate PREMs. The secondary aim is to document and evaluate the approaches used to involve children and adolescents and to assess the impact of their involvement. Based on the European Organisation for Research and Treatment of Cancer framework, we will divide its development and validation into four phases. First, we will discuss PREM items with children and adolescents, who will select and prioritise what they perceive as most important. Second, we will create items targeting different age groups (4–7, 8–12, and 13–17 years) and design a responsive digital interface with child and youth friendly ways of responding to the questionnaires. Third, we will explore how children and adolescents perceive MyHospitalVoice using cognitive interviewing techniques and other age-appropriate methods. Last, we will pilot test MyHospitalVoice to explore patient experiences and response rates. In each phase, children and adolescents will play an active role. We will involve young adults as peer researchers in the project group to ensure that their perspectives are part of the decision-making process.

Discussion
This project will contribute to research on co-creating with children and adolescents and enhance our understanding of their patient experiences. A validated tool like MyHospitalVoice can help improve quality of care by translating the needs and preferences of children and adolescents into clinical practice.

Published: May 2024

Abstract
Background
This study aims to investigate the factors affecting the vitreous levels of pigment epithelium-derived factor (PEDF) and vascular endothelial growth factor (VGEF) among patients with pars plana vitrectomy (PPV). Also, this study correlates the levels of PEDF with RRD characteristics.

Methods
All patients who were scheduled for PPV for any indication were included in the study. They were divided into a case group which included patients with advanced PDR and a control group which included the remaining diagnoses. During the PPV, an undiluted vitreous sample was taken and the enzyme-linked immunosorbent assay method was utilized to measure the levels of VEGF and PEDF.

Results
Eighty eyes were involved. Patients diagnosed with advanced PDR and endophthalmitis exhibited higher levels of VEGF. PEDF was affected inversely by the age of the patients and PEDF levels were higher in RRD and endophthalmitis cases. In patients with RRD, the level of PEDF was higher if the tear was found inferiorly, if the macula was detached, and with a longer duration of RRD.

Conclusions
This study highlights the clinical importance of those biomarkers. Anti-VEGF-based treatment is the mainstay against PDR. PEDF may show a promising predictive values regarding patients with RRD.

Published: May 2024

Abstract
Background
Children with ventricular septal defect (VSD) and large systemic-to-pulmonary shunts eventually develop pulmonary hypertension (PH). The perioperative management of patients with VSD and PH is quite troublesome and still debatable, especially in developing countries where the different management options and standardization of treatment is not available. Oral phosphodiesterase type 5 (PDE-5) inhibitors are good treatment options being widely available, cheap, easy administration and do not require extensive monitoring. The aim of our study was to evaluate the effect of the PDE-5 inhibitors when given orally, early preoperative and continued for 3 months postoperative on controlling postoperative PH with its effect on right ventricle (RV) functions. Fifty-one patients were randomly assigned to either sildenafil or tadalafil, 1 week before and continued for 3 months after corrective surgery. The control group received a placebo.

Results
There was no significant difference in the improvement in the right ventricle systolic pressure (RVSP) between both groups, early in the postoperative period (P = 0.255) and in follow-up (P = 0.259). There was also no significant difference in the changes in mean pulmonary artery pressure (mPAP), postoperatively and on follow-up (P = 0.788 and 0.059, respectively). There was a drop in RV functions in both groups postoperatively which improved on follow-up; however, it was not significant between both groups. The length of intensive care unit (ICU) stay was similar between both groups (P = 0.143).

Conclusion
Perioperative administration of PDE-5 inhibitors does not have an impact on the clinical course as regards improvement in pulmonary artery (PA) pressure, ventricular functions and ICU stay.
Investigation of the effect of field of view on the amount of dental implant artifacts in cone beam computed tomography images
Authors: Mortazavi Samare , Khadem-Reza Zahra Khandan , Parvaresh Mahboube 
Published: May 2024

Abstract
Background
CBCT is widely used in dentistry and is used for a variety of purposes. The presence of different artifacts can reduce the quality of images. Since the implants mainly contain metals, they can cause many artifacts in CBCT images. Due to the importance of CBCT and the effects of artifacts on the final image quality, this study was conducted to investigate the effect of FOV size on the artifacts.

Methods
Three human skulls with unbroken mandible and maxilla were selected. CBCT images were prepared under normal exposure conditions and with three ranges of FOV (4 × 5 cm2, 5 × 8 cm2, 8 × 8 cm2). Then an implant was placed in the empty dental sockets in the incisor, canine, and premolar areas, and CBCT images were taken with similar conditions. The Hounsfield Unit obtained before and after implant placement was compared, and their difference was considered as metal artifact. Data were analyzed using two-factor variance analysis.

Results
In this study, the mean difference of artifacts with a large FOV in both jaws and in the mandible for medium and small radiation ranges from the central to the premolar side was always decreasing. However, in the maxilla for the medium and small radiation ranges, the mean difference increased from the central side to the canine, but again decreased relatively significantly from the canine to the premolar. The mean interaction between the dental areas and the FOV sizes was not significant (p = 0.997), and it was found that the amount of artifacts in the studied areas does not change with changing the size of the FOV. Also there was no significant difference of artifacts between the three types of FOV size (p = 0.730), but there was a significant difference between the dental areas (p = 0.020).

Conclusions
According to the findings of this study, it can be concluded that the amount of metal artifacts is not related to the size of FOV. However, it is related to the position of the implant in the jaws and the density of the surrounding tissues.

Authors: Makhlouf Nahed A. , Mahmoud Amal A. , Medhat Mohammed A. , Saber Asmaa , Elgamal Ahmed F. , Makhlouf Hoda A. , Fadel Bashir A. 
Published: May 2024

Abstract
Background
Liver transplant (LT) recipients are classified as a high-risk group and should receive regular surveillance for COVID-19 and are expected to have higher viral load and prolonged viral shedding. Virus-specific neutralizing antibodies (NAb), induced by infection, can prevent viral infection by deactivating viral access to host receptors.

Aim
To estimate the incidence of SARS-CoV-2 infections and ascertain the levels of NAb among LT recipients.

Method
This cross-sectional study included LT recipients. The survey included 14 parameters about demography, date since operation, and immunosuppressant medications and 11 parameters about COVID-19 infection. NAb was done by electrochemiluminescence immunoassay.

Results
Only 39 LT recipients responded to this survey. Their median age was 57, and 74.4% of them were men. Comorbidities were present in 64% of cases, and DM was the most common comorbidity. Immunosuppressants used were Tacrolimus in 56.4% and Tacrolimus with mycophenolate mofetil in 15.4%. Fifteen cases (38.5%) had suspected infection, and 2 (5.1%) had confirmed infection. Three patients (17.6%) were hospitalized with no mortality. NAb was done in 34 cases, and it was positive in 5 cases (14.7%) with a median level (range) of 0.075 (0.04–27). Three out of 5 cases with a positive NAb test did not give a history of either suspected or confirmed COVID-19 infection.

Conclusion
COVID-19 surveillance in LT recipients is important and suggests a relatively favorable clinical course despite the presumed challenges of immunosuppression. COVID-19 was associated with low hospitalization in LT recipients. NAb indicates a potential immune response even in asymptomatic LT recipients.
