Published: August 2024

Background:
New and innovative materials are being marketed for the treatment of coronal pulpotomy. It is crucial to compare their efficacy with already-established materials. TheraCal PT (TP) is such a new material that studies are scarce.

Aim:
This study aim to compare and evaluate the outcome of coronal pulpotomy using Biodentine and a newly introduced calcium silicate-based dual-cure resin cement, TP, in patients with symptoms of irreversible pulpitis.

Materials and Methods:
Sixty patients with exposed carious pulp and symptomatic irreversible pulpitis were included, aged 18–40, randomly allocated to two groups: TP (group I) and Biodentine (group II). Coronal pulpotomy was performed following a standardized protocol, with TP or Biodentine applied accordingly. The pain was recorded using Visual Analog Scale preoperatively for up to 1 week. Success was assessed clinically and radiographically for up to 12 months.

Statistical Analysis Used:
The data were analyzed using the Friedman test and the Mann–Whitney U-test. Intragroup pain was analyzed using the Wilcoxon signed-rank test.

Results:
Among 60 patients, intervention was done in 53. By removing dropout patients, 47 were analyzed, with 38 available for follow-up at 3, 6, and 12 months. The Biodentine group exhibited a 12-month success rate of 84%, while the TP group revealed 77.3%, with statistically insignificant difference (P = 0.563).

Conclusion:
TP can be effectively utilized as a pulpotomy material in cases of symptomatic irreversible pulpitis in mature permanent teeth, offering rapid setting and ease of use, although Biodentine yielded slightly better results in this study.
Influence of diode laser irradiation on microtensile bond strength of etch-and-rinse adhesive to dentin using two different etchants: An in vitro study
Authors: Naik Asmita Sadanand , De Ataide Ida De Noronha , Fernandes Marina 
Published: August 2024

Aim:
The aim of this study was to evaluate the influence of 970 nm diode laser (DL) irradiation on the microtensile bond strength (µTBS) of etch-and-rinse adhesive (ERA) to dentin using phosphoric acid (PA) or alpha-hydroxy glycolic acid (GA) as etchants.

Materials and Methods:
A total of 32 human third molars were selected and assigned randomly among two different groups and four subgroups based on etching protocols and DL irradiation: PA, PA-DL, GA, and GA-DL. After tooth preparation and subsequent incremental composite build-up, the samples were stored in distilled water for 24 h at 37°C. µTBS values were obtained using the universal testing machine. The failure modes observed in dentin were categorized as adhesive, cohesive within dentin/resin, or mixed.

Statistical Analysis:
The data were analyzed using one-way analysis of variance, followed by Tukey’s post hoc test (P ≤ 0.001).

Results:
GA showed better or similar bond strength values to PA. Furthermore, irradiation of DL increased the µTBS to dentin when both PA or GA are used as etchants.

Conclusion:
GA can be used as an alternative etchant to PA. DL irradiation stands as a promising approach for elevating the performance of ERA adhesive systems to dentin.

Authors: Priya Bharti , Arora Anshul , Taneja Sonali 
Published: August 2024

Background:
Color matching and stability are the essential considerations in restorative dentistry, as they contribute to the longevity and esthetic appeal of the restorations. Composites with nanoparticles and more filler content are anticipated to be more color-stable.

Aim:
The aim of the study was to assess and contrast the color stability of esthetic restoration materials following exposure to various antioxidant beverages.

Materials and Methods:
A Class V cavity was prepared on the buccal surface of 40 maxillary premolars. The specimens were divided into two groups: microhybrid (MH) and nanohybrid (NH) composite. The baseline color of each tooth sample was measured and then, the samples were categorized into four subgroups based on the immersion solution (pomegranate juice, beetroot juice, black plum juice, and distilled water) and evaluated on day 1, day 7, day 14, and day 21 using a spectrophotometer-based on CIE L*a*b* color scale. For spectrophotometer analysis, CIE XYZ data were obtained and converted to CIELAB. The samples mean difference in ΔE values before and after being immersed in various beverages.

Statistical Analysis:
The data were statistically analyzed using an independent t-test and one-way analysis of variance.

Results:
MH and NH composite materials showed color change after being exposed to the test beverages.

Conclusion:
MH composite causes more color change than NH composite at all-time intervals. Black plum showed the greatest discoloration in both composites.

Published: August 2024

Abstract
Monte Carlo (MC) techniques are regarded as an accurate method to simulate the dose calculation in radiotherapy for many years. The present paper aims to validate the simulated model of the 6-MV beam of OMID linear accelerator (BEHYAAR Company) by EGSnrc codes system and also investigate the effects of initial electron beam parameters (energy, radial full width at half maximum, and mean angular spread) on dose distributions. For this purpose, the comparison between the calculated and measured percentage depth dose (PDD) and lateral dose profiles was done by gamma index (GI) with 1%-1 mm acceptance criteria. MC model validating was done for 3 cm × 3 cm, 5 cm × 5 cm, 8 cm × 8 cm, 10 cm × 10 cm, and 20 cm × 20 cm field sizes. To study the sensitivity of model to beam parameters, the field size was selected as 10 cm × 10 cm and 30 cm × 30 cm. All lateral dose profiles were obtained at 10 cm. Excellent agreement was achieved with a 99.2% GI passing percentage for PDD curves and at least 93.8% GI for lateral dose profiles for investigated field sizes. Our investigation confirmed that the lateral dose profile severely depends on the considered source parameters in this study. PDD only considerably depends on the initial electron beam energy. Therefore, source parameters should not be specified independently. These results indicate that the current model of OMID 6-MV Linac is well established, and the accuracy of the simulation is high enough to be used in various applications.
Analysis of vascular thrombus and clinicopathological factors in prognosis of gastric cancer: A retrospective cohort study
Authors: Chen Guo-Yue , Ren Ping , Gao Zhen , Yang Hao-Ming , Jiao Yan 
Published: August 2024

BACKGROUND
Gastric cancer (GC) is one of the most common malignant tumors in the world, and its prognosis is closely related to many factors. In recent years, the incidence of vascular thrombosis in patients with GC has gradually attracted increasing attention, and studies have shown that it may have a significant impact on the survival rate and prognosis of patients. However, the specific mechanism underlying the association between vascular thrombosis and the prognosis of patients with GC remains unclear.
AIM
To analyze the relationships between vascular cancer support and other clinicopathological factors and their influence on the prognosis of patients with GC.
METHODS
This study retrospectively analyzed the clinicopathological data of 621 patients with GC and divided them into a positive group and a negative group according to the presence or absence of a vascular thrombus. The difference in the 5-year cumulative survival rate between the two groups was compared, and the relationships between vascular cancer thrombus and other clinicopathological factors and their influence on the prognosis of patients with GC were analyzed.
RESULTS
Among 621 patients with GC, the incidence of vascular thrombi was 31.7% (197 patients). Binary logistic regression analysis revealed that the degree of tumor differentiation, depth of invasion, and extent of lymph node metastasis were independent influencing factors for the occurrence of vascular thrombi in GC patients (P < 0.01). The trend of the χ 2 test showed that the degree of differentiation, depth of invasion, and extent of lymph node metastasis were linearly correlated with the percentage of vascular thrombi in GC patients (P < 0.01), and the correlation between lymph node metastasis and vascular thrombi was more significant (r = 0.387). Univariate analysis revealed that the 5-year cumulative survival rate of the positive group was significantly lower than that of the negative group (46.7% vs 73.3%, P < 0.01). Multivariate analysis revealed that age, tumor diameter, TNM stage, and vascular thrombus were independent risk factors for the prognosis of GC patients (all P < 0.05). Further stratified analysis revealed that the 5-year cumulative survival rate of stage III GC patients in the thrombolase-positive group was significantly lower than that in the thrombolase-negative group (36.1% vs 51.4%; P < 0.05).
CONCLUSION
Vascular cancer status is an independent risk factor affecting the prognosis of patients with GC. The combination of vascular cancer suppositories and TNM staging can better judge the prognosis of patients with GC and guide more reasonable treatment.

Published: August 2024

BACKGROUND
The intrapapillary capillary loop (IPCL) characteristics, visualized using magnifying endoscopy, are commonly assessed for preoperative evaluation of the infiltration depth of esophageal squamous cell carcinoma (ESCC). Japan Esophageal Society (JES) classification is the most widely used classification. Microvascular structural changes are evaluated by magnifying endoscopy for the presence or absence of each morphological factor: tortuosity, dilatation, irregular caliber, and different shapes. However, the pathological characteristics of IPCLs have not been thoroughly investigated, especially the microvascular structures corresponding to the deepest parts of the lesions' infiltration.
AIM
To investigate differences in pathological microvascular structures of ESCC, which correspond to the deepest parts of the lesions' infiltration.
METHODS
Patients with ESCC and precancerous lesions diagnosed at Peking University Third Hospital were enrolled between January 2019 and April 2023. Patients first underwent magnified endoscopic examination, followed by endoscopic submucosal dissection or surgical treatment. Pathological images were scanned using a three-dimensional slice scanner, and the pathological structural differences in different types, according to the JES classification, were analyzed using nonparametric tests and t -tests.
RESULTS
The 35 lesions were divided into four groups according to the JES classification: A, B1, B2, and B3. Statistical analyses revealed significant differences (aP < 0.05) in the short and long calibers, area, location, and density between types A and B. Notably, there were no significant differences in these parameters between types B1 and B2 and between types B2 and B3 (P > 0.05). However, significant differences in the short calibers, long calibers, and area of IPCL were observed between types B1 and B3 (aP < 0.05); no significant differences were found in the density or location (P > 0.05).
CONCLUSION
Pathological structures of IPCLs in the deepest infiltrating regions differ among various IPCL types classified by the JES classification under magnifying endoscopy, especially between the types A and B.
Aggressive fibromatosis of the sigmoid colon: A case report
Authors: Yu Pan-Pan , Liu Xin-Chun , Yin Lu , Yin Guang 
Published: August 2024

BACKGROUND
Aggressive fibromatosis (AF), also known as desmoid tumor or desmoid-type fibromatosis, is a rare soft tissue neoplasm that can occur in almost any part of the body. Although it is a benign disease, AF is aggressive and infiltrative and has a high recurrence rate after surgery. Common sites for intra-abdominal AF are the small bowel mesentery, retroperitoneum, and pelvis. AF in the colon is extremely rare.
CASE SUMMARY
Here, we report the first case of sigmoid colon AF, which was accidentally discovered in a 27-year-old woman during laparoscopic myomectomy. Computed tomography confirmed a slightly enhanced mass in the sigmoid colon. Subsequent colonoscopy did not reveal a mass in the colonic lumen, but a suspected external compress was found in the sigmoid colon. Surgical disease involving a gastrointestinal stromal tumor was suspected. The patient underwent laparoscopic exploration, and sigmoidectomy with a negative margin was performed to excise the mass. Postoperative immunohistochemistry revealed that the mass was an AF. The patient recovered well and was recurrence-free at the 30-month follow-up without adjuvant therapy.
CONCLUSION
AF should be considered in the differential diagnosis of subepithelial colon masses. Radical resection alone can achieve good outcomes.

Published: August 2024

COVID-19 na gestação e descolamento prematuro de placenta (DPP) são causas relevantes de parto prematuro, ainda são escassos relatos de associação entre eles, mas há evidências de que a má perfusão vascular ou trombose vascular na circulação fetal em ambos os casos pode ser fator importante para este desfecho. A COVID possui complicações imunológicas que aumentam a coagulação em alguns casos e a fisiopatologia da DPP está intimamente ligada à lesão vascular, por rotura ou oclusão, culminado em sangramento vaginal na maioria dos casos. Tais patologias podem ocorrer de forma concomitante em certos pacientes, sendo necessário o estudo para auxiliar no diagnóstico precoce. O artigo em questão apresenta análise de literaturas que colocam em discussão a associação da COVID com o DPP, além de um relato de caso de uma paciente na segunda gestação com uma ampla história patológica pregressa, admitida no pronto socorro ginecológico e obstétrico do Hospital São João Batista, Volta Redonda, apresentando queixas álgicas em baixo ventre e sintomas gripais, onde após realização de exames de imagem e laboratoriais, foi diagnosticada com COVID l e após o período de isolamento respiratório (7 dias) apresentou um quadro de DPP.

Authors: Dolgikh Oleg V. , Dianova Dina G. , Shirinkina Alisa S. 
Published: August 2024

Introduction. The study of sensitization under conditions of aerogenic exposure to aluminum is relevant for preventing the formation of the risk of disorders of the immunological health in the child population.
Materials and methods. Preschool three hundred fifty three children living in Eastern Siberia were examined. Observation group included 199 children living in the zone exposed to emissions from non-ferrous metallurgy enterprises, comparison group – 154 children living in a “conditionally clean” area. In the observation area, the average daily dose of aerogenic exposure to aluminum was 0.292 ∙ 10–3 mg/(kg ∙ day), in the comparison area – 0.0376 ∙ 10–3mg/(kg ∙ day). The work used sanitary-hygienic, chemical-analytical, enzyme-linked immunosorbent and allergosorbent research methods.
Results. In children living under conditions of aluminum exposure, a twofold excess of aluminum content was identified in biological environments relative to the comparison group (p = 0.001), hyperproduction of IgG to aluminum, CD19+ and CD3+CD8+ lymphocytes (1.6 times), and NKT lymphocytes
(2 times) and CD11a+ lymphocytes 1.4 times (p=0.001) was noted, which reflects an imbalance of immunoregulation and the formation of autoallergy.
A significant relationship was established between hyperproduction of total IgE and IgG to aluminum (OR=2.29–5.98; 95% CI 1.76–9.52), (RR=1.93–2.66;
95% CI: 1.41–3.54)
Limitations of the study. Limited sample size.
Conclusion. As markers of allergy and imbalance of immunoregulation in children under conditions of aerogenic exposure to aluminum and with its increased content in biological media, it is necessary to recommend IgG to aluminum as a marker of sensitivity, as well as CD11a+, reflecting the likelihood of developing a risk of developing immunological disadaptation and autosensitization (OR = 2.29–5.98), (RR=1.93–2.66).

Authors: Kim Yeju , Torres Lindy 
Published: August 2024

Problem
Cardiovascular Disease (CVD) is a leading cause of mortality worldwide, and its early and accurate diagnosis is crucial for effective treatment and patient care. Medical imaging, particularly X-ray imaging, plays a crucial role in the detection and assessment of cardiovascular abnormalities. In recent years, Convolutional Neural Networks (CNNs) have emerged as a powerful tool in medical image analysis, demonstrating promising results in various diagnostic tasks.
Proposed Approach
This research paper investigates the application of CNNs for the automated diagnosis of CVD from X-ray images. The CVD diagnosis framework proposed in this study consists of three key modules. The first module is an X-ray feature extractor built using a state-of-the-art CNN architecture. The second module is an age prediction component, which accurately estimates the age of the patients from the X-ray images. Finally, the third module is the CVD classifier, which categorizes the input X-ray images into four predefined severity categories of Cardiovascular Disease.
Result
Through extensive experiments, the proposed method has demonstrated its capability to offer novel insights into the potential use of X-ray images for predicting systemic biomarkers in the diagnosis of CVD. I expect that the proposed CVD diagnosis method can provide a significant advancement in the field of cardiovascular healthcare by offering an accurate, efficient, and automated solution for early detection of CVD.

Published: August 2024

This study focuses on enhancing the reliability and redundancy of electrical systems through machine learning-based fault detection. This project’s objective is to create an inexpensive system for early detection of faults in electrical systems. This study proposed a methodology combining machine learning techniques and feature engineering. A dataset containing 12,001 sensor readings each consisting of six values was examined and analyzed by machine-learning techniques. Results showed the system's success in detecting faults with an accuracy of 99% from only six readings. In economically underserved regions, a common trend is the presence of less sophisticated electrical infrastructures. These systems translate into more frequent and longer power outages, a serious concern when essential institutions like hospitals rely on them to function. This research contributes to the field of fault detection by offering a practical and effective way to improve fault detection in underserved regions.
