Дифференцированный выбор малоинвазивного хирургического доступа в хирургическом лечении желчнокаменной болезни

In 2009 at the University Clinic of the Odessa National Medical University with minilaparoscopic and single-port technology we have operated 47 patients with cholelithiasis. 26 patients were performed minilaparoscopic cholecystectomy, 21 — laparoscopic cholecystectomy using a single laparoscopic access. All surgical interventions had no intraoperative complications. In 5 patients because of anatomic difficulties in removing the gallbladder, we were used to installing an additional trocar in the epigastric region. Time used for interventions ranged from 30 to 130 minutes. Patients were hospitalized after the surgery from 1 to 4 days. Technically, the performance of single-port laparoscopic cholecystectomy was more difficult than the traditional laparoscopic or minilaparoscopic operations due to lack of conditions for the quality triangulation, visualization of anatomical structures in the area of operation and the small angle between the operating instruments. Particular attention was devoted to adequate closure of the abdominal wall defect after installing the port. Pain after use minilaparoscopic surgery was significantly less than with traditional laparoscopic approach. The intensity of pain after single-port operations, was comparable with that of conventional traditional laparoscopy. At follow-up of patients during the first months after surgery separated complications were not observed, marked by a beautiful cosmetic effect. 8 months after surgery 1 patient was diagnosed trocar-site hernia after a single port laparoscopic cholecystectomy.С 2009 г. в клинике Одесского национального медицинского университета прооперировано 47 больных с желчнокаменной болезнью. У 26 больных выполнена минилапароскопическая холецистэктомия, у 21 – однопортовая. Все оперативные вмешательства прошли без интраоперационных осложнений. У 5 пациентов из-за анатомических сложностей мы вынуждены были прибегнуть к установке дополнительного троакара в эпигастральной области. Время, использованное для проведения вмешательств, варьировалось от 30 до 130 мин. Больные находились в стационаре от 1 до 4 сут. При наблюдении за пациентами в течение первых месяцев после операции отдаленных осложнений не наблюдалось, отмечен хороший косметический эффект. Спустя 8 месяцев после операции у 1 пациента после однопортовой лапароскопической холецистэктомии диагностирована троакарная грыжа в месте установки порта

Decisive rule experimental studies to detect objects on the background of nhe earth surface using polarization differences of radar signals

The task of stationary and moving object detection against the background of the underlying surface (earth) by radar means becomes relevant. A decision rule is being developed to detect objects against the background of the earth surface using the polarization differences reflected from the earth and the objects of radar signals, represented as a measurement vecto

Cognitive Impairment in Patients with Diabetes Mellitus

Diabetes mellitus (DM) is a risk factor for the development of cognitive impairment, when unsatisfactory glycemic control is associated with glioma biomarkers and changes in neuronal integrity. Given some limitations in the performance of neuropsychological testing, it is important to indicate specific markers of brain damage

Horizontally scaling dCache SRM with the Terracotta platform

The dCache disk caching file system has been chosen by a majority of LHC experiments Tier 1 centers for their data storage needs. It is also deployed at many Tier 2 centers. The Storage Resource Manager (SRM) is a standardized grid storage interface and a single point of remote entry into dCache, and hence is a critical component. SRM must scale to increasing transaction rates and remain resilient against changing usage patterns. The initial implementation of the SRM service in dCache suffered from an inability to support clustered deployment, and its performance was limited by the hardware of a single node. Using the Terracotta platform, we added the ability to horizontally scale the dCache SRM service to run on multiple nodes in a cluster configuration, coupled with network load balancing. This gives site administrators the ability to increase the performance and reliability of SRM service to face the ever-increasing requirements of LHC data handling. In this paper we will describe the previous limitations of the architecture SRM server and how the Terracotta platform allowed us to readily convert single node service into a highly scalable clustered application

Quick search and synchronization algorithm for wideband noise-like signals

In this regard, the article proposes the fast search and synchronization algorithm for high-orbit satellite telecommunication systems when they are used as the information carriers of broadband noise-like signals with linear frequency modulation. The developed algorithm is based on the consideration of development peculiarities for these signal

Sub-band detection of small-sized objects during airspace sensing with ultra-short radio pulses

The possibility of solving the problem of detecting such objects on the basis of radar soundings in the resonant frequency range of the UHF radio wave range is considered. Sub-band processing of the received signals is proposed, based on the division of the spectral definition area into sub-bands, for adaptation to the frequency response band and noise filterin

Information technologies for creating spatiotemporal modems multiposition active-passive radar systems

The methods of synthesis of the directional diagram of active transmitting antenna arrays when receiving signals reflected from radar targets are considered. It is shown that when using multifrequency orthogonal coherent signals in the elements and addressable access at their reception it is possible to provide a small level of the side lobes of the spatial uncertainty function in a given sector of observation by selecting the type of intrapulse modulation of partial signal

Predicting Multiple ICD-10 Codes from Brazilian-Portuguese Clinical Notes

ICD coding from electronic clinical records is a manual, time-consuming and expensive process. Code assignment is, however, an important task for billing purposes and database organization. While many works have studied the problem of automated ICD coding from free text using machine learning techniques, most use records in the English language, especially from the MIMIC-III public dataset. This work presents results for a dataset with Brazilian Portuguese clinical notes. We develop and optimize a Logistic Regression model, a Convolutional Neural Network (CNN), a Gated Recurrent Unit Neural Network and a CNN with Attention (CNN-Att) for prediction of diagnosis ICD codes. We also report our results for the MIMIC-III dataset, which outperform previous work among models of the same families, as well as the state of the art. Compared to MIMIC-III, the Brazilian Portuguese dataset contains far fewer words per document, when only discharge summaries are used. We experiment concatenating additional documents available in this dataset, achieving a great boost in performance. The CNN-Att model achieves the best results on both datasets, with micro-averaged F1 score of 0.537 on MIMIC-III and 0.485 on our dataset with additional documents.Comment: Accepted at BRACIS 202
