Purpose: to identify patients with erosions at a dental appointment and draw up an individual plan for preventive and therapeutic measures, depending on the identified etiological factors, the degree of destruction of the hard tissues of the tooth and the activity of the process. Materials and methods: 30 patients (14 men and 16 women) were examined for dental erosions, the average age of the participants was 33.66 (±9.58) years. The treatment plan and preventive recommendations were made on the basis of the identified etiological factors, the degree of destruction and the stage of activity of the process. Results: оf the 30 patients, tooth erosion was detected in six of them (20%). Taking hormonal drugs to correct estrogen levels was detected in two patients (6.6%), gastritis with high acidity in one patient (3.3%), an acidic diet combined with aggressive brushing of teeth in one patient (3.3%), Sjögren’s syndrome – in one patient (3.3%), frequent use of carbonated drinks – in one patient (3.3%). According to the degree of destruction of the six patients in whom erosions were detected, I degree was observed in one patient (16.6%), II degree – in two patients (33.3%), III degree – in three patients (50%). According to the activity of the process, out of the identified six patients with erosions, the active stage was observed in four patients (66.6%), the stabilized stage – in two patients (33.3%). Conclusion: the location of erosive lesions is due to an etiological factor or a combination of them. Identification and elimination / minimization of the etiological factor is the most important step in preventing the progression of erosive lesions. The choice of treatment method in patients with dental erosions depends on the degree of destruction of hard tissues and the stage of process activity

Today, an orthopantomogram (OPTG) is a relevant and affordable method for diagnosing the state of anatomical structures of the maxilla-facial region and is frequently used in dentistry. With the help of this method we can detect neoplasms at different stages of development in asymptomatic patients, as well as signs of chronic inflammatory processes, traumatic injuries and other pathologies. The aim of the study is to determine the prevalence of soft tissue and hard tissue neoplasms of the jaws on digital OPTG obtained in the period from 2021 to 2022 at the Department of Pediatric Dentistry and Orthodontics, Samara State Medical University. We analyzed 318 orthopantomographic images, among which 6 images with hard tissue neoplasms (1.89%) and 37 with soft tissue pathological processes (11.64%) were identified. The neoplasms on the upper jaw were twice as frequent (65.47%) than on the lower jaw (34.53%). The study proved the effectiveness of orthopantomography in assessing the structures of the maxillofacial region. Two-dimensional images are an effective way to identify these pathologies at the initial reception of dental patients. To optimize diagnosis and treatment planning it is expedient to use such images and employ elements of artificial intelligence for automation of the analysis, which will enable screening studies of the population of the Russian Federation and meet the modern requirements for oncologic alertness in dental practice.

Published: October 2023

BackgroundLate gadolinium enhancement (LGE) sequences have become common in pediatric cardiovascular magnetic resonance (CMR) to assess for myocardial fibrosis. Bright-blood late gadolinium enhancement (BB-LGE) by conventional phase-sensitive inversion recovery (PSIR) is commonly utilized, but similar inversion time (TI) value of fibrosis and left ventricular (LV) blood pool can make subendocardial areas difficult to assess. A gray-blood LGE (GB-LGE) technique has been described, targeting nulling of the LV blood pool and demonstrating improvement in ischemic scar detection over BB-LGE in adult patients. We sought to evaluate the feasibility of the GB-LGE technique in a young population with congenital and acquired heart disease and compare its ability to detect subendocardial scar to conventional BB-LGE.MethodsSeventy-six consecutive patients referred for clinical CMR underwent both BB-LGE and GB-LGE on 1.5 T and 3 T scanners. Conventional PSIR sequences were obtained with TI to null the myocardium (BB-LGE) in short-axis and horizontal long-axis stacks. Same PSIR stacks were immediately repeated with TI to null the blood pool (GB-LGE). Both sequences were reviewed separately a week apart by two readers, blinded to the initial clinical interpretation. Studies were analyzed for overall image quality, confidence in scar detection, confidence in detection of LGE, LGE class, inter- and intra-observer agreement for the presence of scar, and intraclass correlation coefficient (ICC) for total scar burden.ResultsOverall confidence in myocardial scar detection by BB-LGE or GB-LGE as well as grading of image quality were not statistically different [(p = 1 and p = 1) and (p = 0.53, p = 0.18), respectively]. There was very good inter-observer agreement for the presence of scar on BB-LGE (K = 0.88, 95% CI 0.77–0.99) and GB-LGE (K = 0.84, 95% CI 0.7–0.96), as well as excellent intra-observer agreement for both readers (K = 0.93, 95% CI 0.87–0.99; and K = 0.81, 95% CI 0.69–0.95). Interclass correlation coefficient for total scar burden was excellent for BB-LGE (ICC = 0.98, 95% CI 0.96–0.99) and GB-LGE (ICC = 0.94, 95% CI 0.91–0.97).ConclusionsThe GB-LGE technique is feasible in the pediatric population with congenital and acquired heart disease. It can detect subendocardial/ischemic scar similar to conventional bright-blood PSIR sequences in the pediatric population.

IntroductionEmbryonic chromosomal abnormalities represent a major causative factor in early pregnancy loss, highlighting the importance of understanding their role in spontaneous abortion. This study investigates the potential correlation between chromosomal abnormalities and spontaneous abortion using copy number variation sequencing (CNV-seq), a Next-Generation Sequencing (NGS) technology.MethodsWe analyzed Copy Number Variations (CNVs) in 395 aborted fetal specimens from spontaneous abortion patients by CNV-seq. And collected correlated data, including maternal age, gestational week, and Body Mass Index (BMI), and analyzed their relationship with the CNVs.ResultsOut of the 395 cases, 67.09% of the fetuses had chromosomal abnormalities, including numerical abnormalities, structural abnormalities, and mosaicisms. Maternal age was found to be an important risk factor for fetal chromosomal abnormalities, with the proportion of autosomal trisomy in abnormal karyotypes increasing with maternal age, while polyploidy decreased. The proportion of abnormal karyotypes with mosaic decreased as gestational age increased, while the frequency of polyploidy and sex chromosome monosomy increased. Gene enrichment analysis identified potential miscarriage candidate genes and functions, as well as pathogenic genes and pathways associated with unexplained miscarriage among women aged below or over 35 years old. Based on our study, it can be inferred that there is an association between BMI values and the risk of recurrent miscarriage caused by chromosomal abnormalities.DiscussionOverall, these findings provide important insights into the understanding of spontaneous abortion and have implications for the development of personalized interventions for patients with abnormal karyotypes.

ObjectiveTo build a prediction model for live birth delivery per intracytoplasmic sperm injection (ICSI) in iNOA patients by obtaining sperm by microdissection testicular sperm extraction (mTESE).MethodsA retrospective cohort study of 377 couples with iNOA male partners treated with 519 mTESE-ICSI cycles was conducted from September 2013 to July 2021 at the Reproductive Medical Centre of Peking University Third Hospital. Following exclusions, 377 couples with iNOA male partners treated with 482 mTESE-ICSIs were included. A prediction model for live birth delivery per ICSI cycle was built by multivariable logistic regression and selected by 10-fold cross-validation. Discrimination was evaluated by c-statistics and calibration was evaluated by the calibration slope.ResultsThe live birth delivery rate per mTESE-ICSI cycle was 39.21% (189/482) in these couples. The model identified that the presence of motile sperm during mTESE, bigger testes, higher endometrial thickness on the day of human chorionic gonadotrophin (hCG) administration (ET-hCG), and higher quality embryos are associated with higher live birth delivery success rates. The results of the model were exported based on 10-fold cross-validation. In addition, the area under the mean ROC curve was 0.71 ± 0.05 after 10-fold cross-validation, indicating that the prediction model had certain prediction precision. A calibration plot with an estimated intercept of -1.653 (95% CI: -13.403 to 10.096) and a slope of 1.043 (95% CI: 0.777 to 1.308) indicated that the model was well-calibrated.ConclusionOur prediction model will provide valuable information about the chances of live birth delivery in couples with iNOA male partners who have a plan for mTESE-ICSI treatment. Therefore, it can improve and personalize counseling for the medical treatment of these patients.

Pisha sandstone (PS) is a unique geological structure in the Yellow River basin in China and is a general term for a rock interlayer composed of sandstone, sand shale, and muddy sandstone. The collapsibility of PS results in a high erosion rate and poor vegetation due to its low diagenetic potential and weak structural strength. This study showed that PS can be converted into geopolymer cement by mixing with a suitable alkali activator. PS was converted to geopolymer cement for construction to control soil erosion and conserve the soil and water in this area. Slag was used as a mineral additive to improve the performance of alkali-active PS geopolymer cement in this study. The influence of slag replacement level, NaOH dosages, and curing age on the compressive strength of alkali-activated PS was investigated. Scanning electron microscopy (SEM)/energy dispersive X-ray (EDS), thermogravimetric analyses (TG/DTG), and X-ray diffraction (XRD) were used to analyze the hydration products and microstructure of alkali-activated PS. The results showed that when the samples had 40 wt.% slag, 1.5 wt.% NaOH, and 4.0 wt.% Na2SiO3, their compressive strength could reach 82.0 MPa at 90 days. Compared with the samples with activator and without activator, the compressive strength increased by 6,664% and 9,011%, respectively. The hydration products were C-S-H gel, geopolymer gel, and calcium carbonate crystals. With 10 wt.% slag as a mineral additive, 1.5 wt.% NaOH, and 4 wt.% Na2SiO3 as an activator, the carbonation ratio of C-S-H gel was 49.3%.

Walnut shell breaking is an important aspect of post-harvest processing. However, shell-breaking results differ significantly from ideal uniaxial compression results. In this paper, the effect of multipoint loading on the walnut shell-breaking mechanism by combining FDEM with cohesive elements was investigated. The model for walnuts was created using micro-X-ray CT scans and experimental data. Simulation parameters describing mechanical properties were calibrated through modeling the uniaxial compression experiment. The loading point locations were quantitatively described in terms of top and azimuthal angles. The results show that the crack ex-tension rate increases with the number of loading points and the singularity value, and the maximum value of the four-point loading speed is about 450 m/s. The number of cracks is only related to the number of loading points and is not related to the location of the loading point. In addition, three loading methods are proposed, and the fastest crack propagation rate is achieved when the azimuthal angle of four-point loading is 0, 150, 180, and 330, respectively. These findings may serve as a theoretical foundation for studying shell crushing.
