Despite continuous progress in diagnostics and technology, epidemiologic data on pulmonary trunk health at the population level in Russia remain understudied. In the context of this problem, the present study is an in-depth population-based analysis of the status of pulmonary trunk dilatation using modern technology and artificial intelligence [1]. \u0000Pulmonary trunk dilatation (≥29 mm) may be associated with various pathologies including arterial hypertension, chronic obstructive pulmonary disease, heart failure, and other diseases of the circulatory system [2]. \u0000AIM: The aim of the study was to assess the prevalence of pulmonary trunk dilatation in the Moscow population using artificial intelligence technologies. \u0000MATERIALS AND METHODS: The study was conducted between September 2022 and February 2023 in the population of Moscow. A large amount of chest CT data was analyzed, including information on 134,218 patients (61,514 men and 72,704 women). Artificial intelligence technologies were used to automatically process this data. \u0000RESULTS: The results show that 49,227 (36.7%) patients — 23,720 (38.6%) men and 25,507 (35.1%) women — had evidence of pulmonary trunk dilatation. The analysis shows gender and age differences in the incidence of the pathology. The distribution of pulmonary trunk dilatation in the population shows age dependence. The percentage of patients with signs of pulmonary trunk dilatation increases with age: from 18.1% in the group of young people to 62.2% in the group of elderly people. \u0000CONCLUSIONS: The study provides the first epidemiological data on pulmonary trunk dilatation in Moscow and emphasizes the importance of further research in this area. The findings may serve as a basis for the development of effective diagnostic and treatment strategies, as well as for further research in the field of artificial intelligence in medicine.","PeriodicalId":34831,"journal":{"name":"Digital Diagnostics","volume":"83 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141681888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sosnovtsev, I. Nabiev, P. Samokhvalov","doi":"10.17816/dd627009","DOIUrl":"https://doi.org/10.17816/dd627009","url":null,"abstract":"BACKGROUND: The development of new scintillation materials based on fluorescent nanocrystals with a perovskite structure of CsPbBr3 composition and CdSe/ZnS quantum dots is a pressing topic that is being pursued by numerous scientific groups [1–4]. Both of these materials have a high potential for application in this role due to their excellent fluorophore properties, with a quantum yield of luminescence of approximately 100%. Additionally, they possess high values of the effective atomic Zeff number. The photoelectric cross section is dependent on Zeff as (Zeff)5, while the magnitude of X-ray absorption is dependent on Zeff as (Zeff)4/(AE3), where A is the atomic mass of the substance absorbing the γ-quantum and E is the energy of the X-ray photon [5]. \u0000AIM: The aim of the study was to develop a technique for fabricating scintillators based on quantum dots and polymer matrices with a high degree of transparency, high temporal stability of luminescence quantum yield, and short luminescence decay times (time of illumination or average lifetime of the substance in the excited state) for gamma-ray registration. \u0000MATERIALS AND METHODS: A HAMAMAMATSU R7400U-6 photomultiplier tube was employed to register scintillation signals. A 137Cs source with a γ-quantum energy of 661.7 keV was used as a source of ionizing radiation. \u0000RESULTS: At irradiation with γ-quanta of 137Cs isotope samples based on poly(para-methylstyrene) matrix cross-linked with divinylbenzene molecules (10% wt%), activated with naphthalene (10%, primary acceptor), anthracene (1%) and quantum dots/perovskite nanocrystals (0, 1–1.0%, re-emitter), the energy spectrum showed effective Compton scattering of gamma-quanta in matter on atoms included in quantum dots/perovskite nanocrystals. \u0000The study revealed that samples devoid of inorganic elements, including quantum dots and perovskite nanocrystals, do not exhibit the Compton effect for gamma-quanta. Furthermore, the paramethylstyrene matrix serves to safeguard perovskite nanocrystals from external influences. The photoluminescence quantum yield of bulk composite materials based on perovskite nanocrystals of the CsPbBr3 composition and poly(paramethylstyrene) remains constant over an extended period, with minimal fluctuations within the margin of error. \u0000CONCLUSIONS: Experimental evidence has demonstrated that quantum dots and perovskite nanocrystals encapsulated in various polymer matrices exhibit scintillator properties when subjected to ionizing radiation. The fabricated samples of perovskite nanocrystals/quantum dots and various polymers have been identified as the most promising candidates for use as scintillation material for the registration of X-ray and gamma radiation.","PeriodicalId":34831,"journal":{"name":"Digital Diagnostics","volume":"83 S16","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141682157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Shklyaev","doi":"10.17816/dd626507","DOIUrl":"https://doi.org/10.17816/dd626507","url":null,"abstract":"BACKGROUND: One of the primary pathophysiological mechanisms of functional dyspepsia is a disruption in the postprandial reflex relaxation of the proximal part of the stomach, which results in an impairment of its motor-evacuation function. This impairment can be verified by magnetic resonance imaging with a stress drinking test. Correction of gastric relaxation accommodation disorders in functional dyspepsia is possible with the help of drinking mineral waters. However, further studies are required to assess the effect of these waters on the motor-evacuation function of the stomach. \u0000AIM: The study was aimed at comparative evaluation of the effect of intake of therapeutic medium mineralized sulfate-sodium-calcium mineral water and ordinary drinking water on gastric evacuation function using magnetic resonance tomography. \u0000MATERIALS AND METHODS: A two-fold magnetic resonance imaging procedure was conducted on an empty stomach using a closed-type Philips Intera 1.5T device (Philips, Netherlands) in 10 patients aged 22.8±1.2 years with a diagnosis of functional dyspepsia. On day 1, 200 ml of drinking water was used, and on day 2, 200 ml of mineral water was used. The examination was conducted in abdominal mode, with the subjects lying on their back. A slice thickness of 3 mm was used in coronal, axial, and sagittal projections, with images acquired every 5 minutes for 20 minutes. The following imaging modes were employed: T1, T2-weighted images, T2 Spair, and b-FFE. The volume of gastric contents and the rate of fluid evacuation were calculated using the RadiAnt DICOM Viewer program (Medixant, Poland). \u0000RESULTS: In patients with functional dyspepsia, the volume of liquid in the stomach after ingestion of 200 ml of drinking water was 163.71 ± 28.9 mL, while after ingestion of mineral water, the volume was 101.57 ± 26.88 mL. Furthermore, the volume of evacuated liquid after ingestion of mineral water was 1.040–2.5 times greater. By minute 15, the volume of liquid in the stomach was 8.0 ± 6.16 mL after mineral water intake and 58.85 ± 40.06 mL after drinking water. The mean gastric evacuation rate following ingestion of ordinary drinking water was 12.9 ± 5.29 mL/min, while that following ingestion of mineral water was 24.1 ± 4.53 mL/min (1.07–3.76 times greater). The increase in gastric evacuation rate observed in the examined subjects when using mineral water ranged from 7.58% to 276.21%. \u0000CONCLUSIONS: Magnetic resonance imaging of the stomach allows for the verification of the effect of mineral water on its motor-evacuation function, thus enabling the estimation of the rate of gastric emptying. A single intake of the studied mineral water has a prokinetic effect, which can be used to correct motor disorders in patients with functional dyspepsia.","PeriodicalId":34831,"journal":{"name":"Digital Diagnostics","volume":"112 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141683815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Melnikov","doi":"10.17816/dd626180","DOIUrl":"https://doi.org/10.17816/dd626180","url":null,"abstract":"BACKGROUND: Ferroptosis plays a pivotal role in the pathophysiology of secondary disorders following brain injury. Disturbances in iron homeostasis result in the accumulation of iron and the formation of reactive oxygen species, which may contribute to the development of various neurodegenerative diseases. Magnetic susceptibility mapping is a novel, rapidly evolving quantitative technique with significant potential for assessing iron accumulation in the brain. \u0000AIM: The study aimed to determine changes in brain iron concentrations in patients with brain injury using magnetic susceptibility mapping techniques. \u0000MATERIALS AND METHODS: The study included 9 patients (14±2 years) with moderate and severe brain injury: three in the acute phase and six in the remote phase, and 4 healthy volunteers (15.3±0.9 years). All study participants underwent magnetic resonance imaging on a Philips Achieva dStream 3T scanner (Philips, the Netherlands). Data for magnetic susceptibility maps were acquired using a 3D FFE multi-echo sequence with flux compensation: FA=20, 6 TE: TE1/dTE=4.422 ms/5.795 ms, TR=59 ms (minimum), matrix size was 400×400×75, voxel size was 0.6×0.6×0.6 mm3. Magnetic susceptibility maps were generated using the SEPIA program. Magnetic field map construction, local magnetic field extraction, and magnetic susceptibility calculation were performed using the Laplacian, LBV, and iLSQR techniques, respectively. Average magnetic susceptibility values were obtained in 16 subcortical gray matter zones using the CIT168 atlas. \u0000RESULTS: The preliminary results of the study indicated that the patient group exhibited higher magnetic susceptibility values (p=0.07) in the compact part of the substantia nigra compared to the control group. The values for the patient and control groups were 0.03±0.03 and 0.003±0.018, respectively (Fig. 1). This result suggests a potential difference between the two groups at the level of a statistical trend, which may indicate iron accumulation in this area following brain injury. No changes in the values of magnetic susceptibility were observed in other areas of the subcortical gray matter that were investigated. \u0000An increased iron concentration in the compact part of the substantia nigra is also a characteristic of Parkinson’s disease [3]. This is consistent with the fact that brain injury is a risk factor for the development of this neurodegenerative disease. One of the possible causes of iron accumulation is neuronal death and increased permeability of the blood-brain barrier [4]. \u0000CONCLUSIONS: An elevated magnetic susceptibility value in the compact part of the substantia nigra in patients with brain injury may indicate the accumulation of iron in this area following injury. A larger sample size will allow for further testing of this hypothesis and the monitoring of changes in iron concentration over time following brain injury.","PeriodicalId":34831,"journal":{"name":"Digital Diagnostics","volume":" 38","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141680805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recognizing them is not easy if one has never seen them and does not have access to the right imagery. The aim of the study is to expand the radiologist's digital image library, enabling a quick and precise differential diagnosis. Indeed, multiple biliary hamartomas can be challenging to differentiate from other liver lesions based on imaging alone. This case highlights the importance of thorough radiological assessment and the need for a multidisciplinary approach, involving radiologists, hepatologists, and pathologists, to ensure a precise diagnosis. \u0000METHODS: The patient in the study presented at the hospital for a CT scan and after an abdominal MRI recommended by his general practitioner to assess the biliary tree (Magnetic Resonance Cholangiopancreatography, MRCP) due to persistent abdominal pain. They had never undergone an abdominal MRI before in their life. The discovery of hepatic lesions was incidental and unexpected \u0000RESULTS: The MRI investigation revealed multiple benign lesions in both hepatic lobes compatible with the von Meyenburg complex. These lesions are multiple hamartomas and behave differently in all MRI sequences. \u0000CONCLUSIONS: The images acquired with the different MRI sequences were carefully examined. Despite being multiple and scattered throughout the liver, the lesions appeared immediately benign and consistent with the incidental diagnosis of multiple biliary hamartomas. Medical practitioners should be aware of the existence of multiple biliary hamartomas and consider them in the differential diagnosis when patients present with hepatic abnormalities. This knowledge can prevent unnecessary interventions and guide appropriate patient management.","PeriodicalId":34831,"journal":{"name":"Digital Diagnostics","volume":"105 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141687248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Implantation of recent IOLs allows ophthalmologists to effectively solve the problems of surgical rehabilitation of patients with cataracts. The degree of improving the patient's visual functions is directly dependent on the accuracy of the preoperative calculation of the optical power of IOLs. The most famous formulas to calculate this indicator are SRK II, SRK/T, Hoffer-Q, Holladay II, Haigis, Barrett. All of them work well for an \"average patient\", however, they are not adequate enough at the boundaries of input variables ranges. \u0000Aims. To study the possibility of using mathematical models obtained as a result of deep learning of artificial neural networks (ANN models) to generalize data and predict the optical power of modern intraocular lenses. \u0000Materials and methods. ANN models were trained on large-scale samples, including depersonalized data for patients of ophthalmology clinic. Data provided in 2021 by ophthalmologist K.K. Syrykh, and reflect the results of both preoperative and postoperative observation of patients. The source file used to build the ANN model includes 455 records - 26 columns of input factors and one column for the output factor - calculating IOL (diopters). To conveniently build ANN models, we used a simulator program, previously developed by the authors. \u0000Results. The resulting models, in contrast to the traditionally used formulas, reflect the regional specificity of patients to a much greater extent. They also make it possible to retrain and optimize the structure based on newly received data, which allows taking into account the non-stationarity of the object. A distinctive feature of such ANN models in comparison with the well-known formulas SRK II, SRK/T, Hoffer-Q, Holladay II, Haigis, Barrett, widely used in the surgical cataract treatment in ophthalmology, is their ability to take into account a significant number of recorded input quantities, which makes it possible to reduce the mean relative error in calculating the optical power of IOL from 10–12% to 3.5%. \u0000Conclusions. This work shows the fundamental possibility of generalizing a significant amount of empirical data on calculating the optical power of the IOL using training ANN models that have a significantly larger number of input variables than when using traditional formulas and methods.
