Abstract
Cultural heritage management poses significant challenges for museums due to fragmented data, limited intelligent frameworks, and insufficient applications. In response, a digital cultural heritage management approach based on knowledge graphs and deep learning algorithms is proposed to address the above challenges. A joint entity-relation triple extraction model is proposed to automatically identify entities and relations from fragmented data for knowledge graph construction. Additionally, a knowledge completion model is presented to predict missing information and improve knowledge graph completeness. Comparative simulations have been conducted to demonstrate the effectiveness and accuracy of the proposed approach for both the knowledge extraction model and the knowledge completion model. The efficacy of the knowledge graph application is corroborated through a case study utilizing ceramic data from the Palace Museum in China. This method may benefit users since it provides automated, interconnected, visually appealing, and easily accessible information about cultural heritage.

AbstractThe identification and prognosis of the potential for developing Cardiovascular Diseases (CVD) in healthy individuals is a vital aspect of disease management. Accessing the comprehensive health data on CVD currently available within hospital databases holds significant potential for the early detection and diagnosis of CVD, thereby positively impacting disease outcomes. Therefore, the incorporation of machine learning methods holds significant promise in the advancement of clinical practice for the management of Cardiovascular Diseases (CVDs). By providing a means to develop evidence-based clinical guidelines and management algorithms, these techniques can eliminate the need for costly and extensive clinical and laboratory investigations, reducing the associated financial burden on patients and the healthcare system. In order to optimize early prediction and intervention for CVDs, this study proposes the development of novel, robust, effective, and efficient machine learning algorithms, specifically designed for the automatic selection of key features and the detection of early-stage heart disease. The proposed Catboost model yields an F1-score of about 92.3% and an average accuracy of 90.94%. Therefore, Compared to many other existing state-of-art approaches, it successfully achieved and maximized classification performance with higher percentages of accuracy and precision.

Abstract
Background
According to National Institute for Health and Care Excellence (NICE), UK, common audiovestibular symptoms of COVID-19 include dizziness, tinnitus, and otalgia. The pathogenesis of otologic disorders ranges from direct damage to the inner ear structures to immune-mediated damage. Since the start of the pandemic, the prevalence of audiovestibular symptoms linked to COVID-19 has not been thoroughly investigated in Egypt. Our objective is to study and analyze the prevalence of the audiovestibular symptoms in the Egyptian population with history of COVID-19 infection.

Methods
A cross-sectional study was conducted among Egyptian adults on the presence and nature of the audiovestibular manifestations in COVID-19 patients. An online questionnaire was used. The questionnaire was developed using Google Form. It was disseminated to the target population through social platforms from October 2021 till February 2022.

Results
Data from 245 respondents were collected through online assessment of a convenient sample. The following de novo audiovestibular symptoms were experienced by the participants: Vertigo 20.8%, hearing loss 13.9%, tinnitus 12.7% and ear fullness 11.4%. No correlation was found between the investigations done (D-Dimer, CT chest) and the audiovestibular symptoms.

Conclusion
Audiovestibular symptoms are fairly common among COVID-19 patients, with higher prevalence, particularly of vertigo, in our study sample compared to the literature. It is recommended that patients with audiovestibular symptoms undergo early testing so that prompt interventions can be taken.

Published: September 2023

Abstract
Background
The emergence of antimicrobial resistance to antifungals has made vulvovaginal candidiasis a concern. Coconut oil has antimycotic properties that could have a synergistic effect when combined with antifungals. Thus, clotrimazole suppositories were prepared using coconut oil as a base to improve its use and delivery in antimycotic treatment and the suppositories were evaluated for their physicochemical, mechanical, and drug release properties, and the antimycotic effect of clotrimazole and coconut oil was examined singly and in combination, as well as their formulations using the agar-well diffusion method in comparison with polyethylene glycol (PEG), and cocoa butter bases. Using the fusion method, coconut oil was solidified with beeswax (20–50%) to prepare 100 mg clotrimazole suppositories. Surfactants (4% w/w); Tween 20®, Span 20®, sodium lauryl sulphate, and their combinations (3% w/w ratio 1:1 of Tween 20® and Span 20®) were used to improve the rate of drug release from the suppository.

Results
The suppositories had a pH of 4.1–6.0 and crushing strengths of 0.53 ± 0.07–32.56 ± 5.42 N. Suppositories containing surfactants and those prepared from PEG had significantly (p < 0.05) lower disintegration times ranging from 35 to 90 min than those without surfactants ranging from 305 to 388 min. Drug release (t80) was the fastest from the suppositories containing 40% coconut oil, Tween 20, and PEG. Using the Korsmeyer–Peppas’ model, suppositories made from PEG had a non-Fickian diffusion, while those containing 40% coconut oil, and Tween 20 had a super case II transport mechanism. The combination of clotrimazole and coconut oil gave higher zones of inhibition against Candida species compared to either clotrimazole or coconut oil alone. The formulations had higher antimycotic activities against Candida albicans than Candida krusei and Candida tropicalis.

Conclusion
The optimized formulation with the desired physicochemical and drug release properties was obtained with coconut oil (40% w/w) solidified with beeswax (50% w/w) as a base. Coconut oil appeared to possess a synergistic antimycotic effect on clotrimazole. Thus, clotrimazole vaginal suppositories with coconut oil as a base in the treatment of vulvovaginal candidiasis showed potential against C. albicans and other Candida species.

Authors: Sugaya Akira , Muraoka Arata , Doi Masayuki , Kawahito Koji 
Published: September 2023

Abstract
Background
Aerococcus urinae infection is a rare clinical condition that causes urinary tract infections in older individuals. Infective endocarditis (IE) caused by A. urinae in healthy young men is extremely rare; however, the mortality rates of IE caused by A.urinae are high if appropriate surgical treatment is not performed.

Case presentation
A 39-year-old healthy man was admitted to our hospital with complaints of fever, cough, and dyspnea. Blood cultures revealed gram-positive cocci, and echocardiography revealed a 20 × 12-mm vegetation on the aortic valve and perforation of the anterior mitral valve leaflet. He was diagnosed with IE and underwent aortic valve replacement and mitral valve repair after removal of the infective focus. Matrix-assisted laser desorption ionization time-of-flight mass spectrometry was used to identify A. urinae. The patient was discharged in good health after 6 weeks of ampicillin/sulbactam therapy.

Conclusion
Prompt diagnosis and surgical removal of infectious foci with optimal antibacterial therapy are critical to protect patients from rare and potentially fatal IE caused by A. urinae.

Published: September 2023

Background: Catheter-associated urinary tract infections (CAUTI) constitute a significant portion of healthcare-associated infections. Using antiseptic for routine daily perineal care of patients with IUC may reduce CAUTIs.
Aim: This study aimed to examine antimicrobial photodynamic inactivation (aPDI) against clinical isolates for use in the daily perineal care of patients with IUC. In addition, it was also aimed to compare the antimicrobial activities of aPDI and 0.1% chlorhexidine gluconate.
Methods: In this in-vitro study, cationic porphyrin derivatives (CPDs) were used as photosensitizers in the experiments. CPDs, named PM, PE, PN, and PL were synthesized by the researchers. A diode laser device emitting light with a wavelength of 450 nm (blue light) was used as the light source. Methicillin-resistant Staphylococcus aureus (MRSA), Escherichia coli and Klebsiella pneumoniae with multidrug-resistant (MDR) properties and Candida albicans were used. Photosensitizer (PS), aPDI, light (L), and control (C) groups in aPDI experiments; control (C) and chlorhexidine gluconate 0.1% groups were used in the chlorhexidine gluconate experiments. Survival was calculated based on CFU/mL in the control group.
Results: In experiments, combinations of 25 J/cm² with 6.25 and 3.125 µM PM, PE reduced E. coli, K. pneumoniae, MRSA, and C. albicans survival in the range of 8.70 to 11.53 log₁₀. In aPDI experiments performed with 6.25 and 3.125 µM PN and PL concentrations at the same energy density, reductions in the range of 4.41 to 0.17 log₁₀ were observed in all four clinical isolates. In experiments where 1.5625 µM concentration was used, survival decreased in the range of 8.29 to 10.87 log₁₀ in PM and PE, while antimicrobial activity was limited in PN and PL. In the 0.1% chlorhexidine gluconate experiments, the survival reduction in all four clinical isolates ranged from 8.87 to 10.24 log₁₀.
Conclusion: For PM and PE, a very strong aPDI was obtained in C. albicans, E.coli, K. pneumoniae, and MRSA at low concentrations and energy density. The same antimicrobial activity was found in experiments using 0.1% chlorhexidine gluconate. In this context, we would like to inform you that aPDI to be performed with a combination of 25 J/cm² at 6.25 and 3.125 µM concentrations of PM and PE has the potential to be an antiseptic in the daily perineal care of patients with IUC.

Aim. To determine the incidence and predictors of cardiovascular events in onpump cardiac operations in modern practice.Material and methods. The study included 200 patients who underwent various elective cardiac surgical interventions. Cardiovascular events (CVEs) were determined within 30 days from the operation, according to medical records and autopsy protocols. We identified major CVEs (cardiovascular death, stroke, myocardial infarction) and minor CVEs (angina pectoris, significant ventricular arrhythmias, atrial fibrillation or flutter episodes, AV conduction disorders, etc.). A comprehensive preoperative examination was performed, including an extended echocardiography protocol and coronary angiography.Results. In 101 patients (50,05%), various CVEs were identified: 4,0% had major CVEs and 46,05% had minor CVEs and various non-cardiac complications, while perioperative mortality was 2,0%. Most ischemic CVEs, as well as most intracardiac conduction disorders, were registered during the first 3 days after surgery. In contrast, episodes of atrial fibrillation/flutter occurred 2-7 days after the intervention. There were following preoperative examination parameters with the highest prognostic value: history of heart failure, age >65 years, history of myocardial infarction, occlusion of at least one coronary artery, and diabetes.Conclusion. The data obtained indicate the high efficiency of current surgical and anesthetic technologies, which lead to relatively low risk of severe and fatal events. The parameters of the preoperative examination, which determine the increased risk of intervention, are highlighted.

Aim. To obtain extended data on the impact of collateral circulation on the recovery of left ventricular (LV) function after recanalization of chronic coronary total occlusion (CTO), especially in patients with reduced left ventricle ejection fraction (LVEF).Material and methods. This single-center, prospective, non-randomized study included 20 patients with single-vessel CTO with reduced LVEF (<50%), confirmed by magnetic resonance imaging (MRI), who underwent successful recanalization. All patients were divided into 2 groups depending on the severity of collateral circulation. After 1, 3 and 6 months, MRI was repeated to assess LV function recovery.Results. All patients had prior myocardial infarction, while in 70% of cases — in the area of the occluded artery. A previous attempt to recanalize CTO was noted in 30%. The mean baseline LVEF according to echocardiography was 38,80±6,72%. The most common target vessel was the right coronary artery (n=17, 85%), followed by the circumflex and anterior descending arteries — 1 (5%) and 2 (10%) patients, respectively. In the group with high collateral circulation, the initial LVEF according to MRI was higher compared to the group with mild collateral circulation (35,8±7,33% vs 30,7±8,82%, p=0,17). After 6 months, MRI showed significant changes in end-diastolic volume (from 226±71,1 ml to 203±55,2 ml) and LV endsystolic volume (from 153±72,8 ml to 118±57,6 ml), as well as mean increase in LVEF by 3,3%, 4,8% and 5,2% at 1, 3 and 6 months, respectively (p=0,01 compared with baseline). The predictors of LVEF recovery in multivariate regression analysis were the initial LVEF according to MRI, and the filling rate of distal CTO bed on coronary angiography (R2=0,63).Conclusion. Successful percutaneous coronary intervention with CTO improves LV function in patients with ischemic cardiomyopathy, regardless of the degree of collateral circulation. LV function recovery generally occurs within 3 months after revascularization.

Published: September 2023

Aim. To compare cardiac magnetic resonance imaging (MRI) parameters with known prognosis determinants in patients with pulmonary hypertension (PH).Material and methods. This prospective single-center study included 60 patients with PH aged 21-72 years. Cardiac MRI, right heart catheterization, echocardiography, N-terminal pro-brain natriuretic peptide (NT-proBNP) and 6-minute walk test (6MWT) were assessed at baseline.Results. Significant correlations between invasive hemodynamic parameters, NTproBNP and cardiac MRI parameters were confirmed. There were no significant correlations between the right ventricular (RV) contractility, RV volume and 6MWT distance, the functional class of PH. Cardiac MRI values allowed us to reliably separate patients at low risk from those at intermediate and high risk according to the 2015 ESC/ERS score. According to multivariate regression analysis, the right ventricular end systolic volume index >54 ml/m2 (hazard ratio, 0,2; 95% confidence interval, 0,05-0,9; p=0,004) and class 3-4 PH (hazard ratio, 0,2; 95% confidence interval, 0,07-0,8; p=0,026) remained independent predictors of mortality.Conclusion. The use of cardiac MRI in low-risk patients can significantly improve the early detection of right ventricular myocardial dysfunction and contribute to the timely optimization of PH-specific therapy. During monitoring patients with PH, cardiac MRI has the potential to reduce the need for repeated invasive investigations.

Published: September 2023

The reactivation of polyomavirus BK (BKPyV) contributes to increased morbidity and mortality rates of transplant patients, especially kidney transplant recipients (KTRs). CD4+ T cells are important immune cells active during BKPyV infection in KTRs. This research tried to examine the phenotype of CD4+ T cells in the stage of BKPyV activation in KTRs.
The recipients were separated into 2 groups of BKPyV-active and nonactive KTRs (10 patients in each group) and were compared with 10 healthy control subjects. The viral load was evaluated by Taq-man quantitative real-time PCR. The frequency of different CD4+ T cell subsets was determined by analyzing markers such as CD45RO, CCR7, CD27, CD107a, perforin, and granzyme B using flow cytometry. The gene expression levels of transcription factors, including TBX21, GATA3, STAT3, and STAT6, contributing to CD4+ T cell activation, were also assessed.
A significantly higher proportion in CCR7+CD27+CD45RO-CD4+ T cell (naive Tcell) subsets was detected in BKPyV-active KTRs compared to nonactive ones. A significant increase was detected in the frequency of CD107a+, perforin+, and granzyme B+ CD4+ T cells in the BKPyV-active group compared to the nonactive group. In CD4+ T cells of KTRs, the mRNA expression of TBX21 and GATA3 was significantly increased in KTRs without BKPyV reactivation compared to BKPyV-active ones.
This investigation focused on the CD4+ T cell as an immunodominant T cell type with potential cytotoxicity. Based on these results, BKPyV may have a direct influence on the repertoire of CD4+ T cell subsets. Particularly, cytotoxic CD4+ T cells need further investigation to be considered as a therapeutic approach for BKPyV infection.

Published: September 2023

Background: Mosquito Control Programs are articulated to control Mosquito Borne Diseases and success of such programs depends on the activities of field workers, and their adherence to the standard operating procedures (SOP’s) is governed by their knowledge, attitudes, and practices (KAP). Present study was intended to assess the KAP of mosquito control workers of Pakistan to get an exact depiction of prevailing situation.
Methods: A cross-sectional descriptive study was conducted in March-April 2020. Questionnaire containing 30 closed and open-ended questions were administrated to participants. Knowledge and practices were evaluated using a scoring system i.e., by giving 1 point to each correct answer while attitude questions were analyzed individually and expressed in percentage for each response.
Results: Total 639 workers were interviewed, mean age was 29.8 (SD ±7.87) years, majority (65.1%) was in age group of 18–30 years. Mean knowledge score was 6.96±1.28 (range 0–9) with 77.36% correct answers (P= 0.073). Mean prac­tices score was 7.00±1.62 (range 2–9) with 77.83% appropriate answers (P< 0.001). Both knowledge and practices scores were higher for permanent employees, practices score increased with increase in job experience. Very weak posi­tive correlation (r= 0.127) was observed between knowledge and practice scores.
Conclusion: Appropriate practice correlates with better knowledge and positive attitude towards control activities. Hence, training on protection and protective measures for having a positive attitude among healthcare workers is neces­sary against the fight with mosquitoes.
