Safety of the Inari FlowTriever device for mechanical thrombectomy in patients with acute submassive and massive pulmonary embolism and contraindication to thrombolysis
Authors: Markovitz Michael , Lambert Nicholas , Dawson Lowell , Hoots Glenn
Published: December 2020

Objectives:

This report evaluates the safety of percutaneous mechanical thrombectomy with the Inari FlowTriever System (Inari Medical, Irvine, California) for the treatment of acute massive/submassive pulmonary embolism (PE) specifically in therapeutically anticoagulated patients with contraindication to thrombolysis.

Material and Methods:

A single-center retrospective chart review was performed on patients with contraindication to thrombolysis and massive/submassive PE who underwent FlowTriever thrombectomy between 2017 and 2019. Primary outcomes included procedure or device-related complications within 30 days of discharge. Secondary outcomes included technical and clinical success defined by improvement in mean pulmonary artery pressure (PAP), oxygen saturation, and heart rate.

Results:

Thirteen patients with contraindication to thrombolysis received FlowTriever thrombectomy with technical success achieved in all cases. Zero major or minor adverse events, technical complications, delayed procedure-related complications, or deaths within 30 days of hospital discharge occurred. Mean PAP decreased significantly by 19.1% (32.5 ± 13.3 mmHg to 26.3 ± 12.4 mmHg; P = 0.0074, 95% confidence interval (CI) 2.0–10.5 mmHg). Oxygen saturation improved post-procedure (increased 3.9 ± 3.8%; p = 0.0032, 95% CI 1.6– 6.1%) as did heart rate (decreased 22.2 ± 17.0 bpm; P < 0.001, 95% CI 11.9–32.4 bpm). Anticoagulation was maintained throughout every procedure and all patients were closed with purse-string suture only.

Conclusion:

FlowTriever mechanical thrombectomy appears safe for acute PE in therapeutically anticoagulated patients with contraindications to thrombolytic therapy. These patients may experience immediate hemodynamic improvements similar to those reported in other studies. Further data are needed to prospectively evaluate long-term safety in this population.

Herein we present the preparation of two novel cyclam-based macrocycles (te1pyp and cb-te1pyp), bearing phosphonate-appended pyridine side-arms for the coordination of copper(II) ions in the context of 64Cu PET imaging. The two ligands have been prepared through conventional protection-alkylation sequences on cyclam, and their coordination properties have been thoroughly investigated. The corresponding copper complexes have been fully characterized in the solid-state (X-Ray diffraction analysis) and in solution (EPR and UV-Vis spectroscopies). Potentiometric studies, combined with spectrometry, have also allowed us to determine their thermodynamic stability constants, confirming their high affinity for copper(II) cations. The kinetic inertness of the complexes has also been verified by acid-assisted dissociation experiments, enabling their use in 64Cu-PET imaging in mice for the first time. Indeed, the two ligands could be quantitatively radiolabeled under mild conditions, and the resulting 64Cu complexes have demonstrated excellent stability in serum. PET imaging demon-strated a set of features emerging from the combination of picolinates and phosphonate units: high stability in vivo, fast clear-ance from the body via renal elimination, and most interestingly, very low fixation in the liver. The latter is in contrast with what was observed for monopicolinate cyclam (te1pa), that had a non-negligible accumulation in the liver, owing probably to its different charge and lipophillicity. These results thus pave the way for the use of such phosphonated pyridine chelators for in vivo 64Cu-PET imaging.

Published: December 2020

For the first time a section appeared for staging of non-organ retroperitoneal tumors in the UICC TNM classification 8th edition.
Aim.To assess the prognostic significance of the TNM classification eighth edition for the most common retroperitoneal tumors-liposarcoma.
Materials and methods.The distribution of patients by stages and survival in accordance with the TNM-8 classification were studied in192 patients with retroperitoneal non-organ liposarcoma (RLPS).
Results.In the TNM-8 classification, only the degree of malignancy of the tumor has a prognostic value, and the T-category does not reflect the actual size of the RLPS and is considered T4 in 93%, which leads to inadequate staging. During the 15-year period, there were no cases with stages II and IIIA, and the survival rate was estimated only in patients with stages I and IIIB. A TNM classification with new values of the T-category was proposed, which demonstrated a more adequate distribution of patients by stages and the reliability ofintergroup differences in the survival rate.
Conclusion.It is advisable to create a special TNM classification for RLPS, which makes up more than half of all retroperitoneal sarcomas.

The construction of the turbulence phenomenological theory in a liquid with drug reducing additives
Authors:   Gubkin Russian State University of Oil and Gas (National Research University), Golunov Nikita N. , Lurie Mikhail V. ,   Gubkin Russian State University of Oil and Gas (National Research University)
Published: December 2020

In the paper, the question of the construction of the turbulence phenomenological theory in liquids with small drag reducing additives (DRA) is considered. The thesis is put forward that the phenomenological theory is relevant for practical needs, since it determines the parameters of the phenomenon under consideration without using in detail the mechanisms that determine its effect. These mechanisms, despite many years of intensive research to date, remain either unknown or not fully understood. It is argued that different DRAs act differently on shear turbulence in pipes and channels and therefore change the integral characteristics of turbulent flow differently. Some DRAs act only on narrow near-wall regions of the flow, without changing the turbulent viscosity in the flow core, while others DRAs act in the entire volume of the turbulent flow, and significantly change the turbulent viscosity. The first type of DRAs form a turbulent flow by changing the boundary conditions in known models without changing the model coefficients. The second type of DRAs changes both the boundary conditions and the coefficients of the model itself. It is shown that the modified theory (model) of Karman shear turbulence is equally suitable for describing the turbulent fluid flow with DRAs of the first and second types. The universal resistance equation resulting from this model, with experimentally determined transfer coefficients, allows calculating the hydraulic resistance coefficient depending on the properties of the used DRAs.
The method of determining the polarization potential during corrosion surveys of underground pipelines
Authors:   Science & Technology Centre of Pipeline Transportation of Transneft R&D, LLC, Bolotov Andrey А.
Published: December 2020

Values of metal potentials, which exceed or equal to the potential at which the corrosion rate of the metal does not exceed 0.01 mm/year, in international practice, are a condition for the effectiveness of cathodic protection of underground pipelines. It is called polarization potential. The range of polarization potentials, which correspond to effective corrosion protection, was determined experimentally as a result of a large number of field tests in different operating conditions. The values of polarization potentials can vary from minus 0.65 V to minus 1.15 V, measured relative to copper sulfate electrode (C.S.E). There are cases during corrosion surveys of underground pipelines, when the measured values of polarization potentials with the help of measuring instruments, intended for this purpose, significantly exceed the maximum permissible value. The author offers an original method for determining the polarization potential based on the analysis of the dependence of the auxiliary electrode potential on the time after the interruption of the polarization current. The values of polarization potentials obtained using this technique are in the standard range. The method can be recommended for experimental use in corrosion surveys of underground pipelines in various operating conditions in order to confirm the compliance of the obtained results with the condition of cathodic protection efficiency.

Authors:   Gubkin Russian State University of Oil and Gas (National Research University), Shmakov Timur G.
Published: December 2020

For electrification of decentralized energy consumption facilities, as a rule, constructed an autonomous diesel power station, the operation of which involves the use of diesel fuel mainly to start the unit, and the rest of the time the diesel generator sets operate on treated oil. To reduce fuel consumption (treated oil) and reduce the load on diesel generators, it is proposed to use as the main power source for oil pumping stations, located in regions with high wind energy potential – an autonomous hybrid power-supply system – wind-diesel power station with a parallel operation of the wind and diesel power station. The article provides an operation scheme of a wind-diesel power station. In case when there is no possibility to place diesel generator sets of the equivalentcapacity in the powerhouse hall, then the article describes the optimal calculation algorithm for power distribution between diesel generator sets with different capacity, based on solving simultaneous equations by using the Lagrange multiplier method. The article also provides a practical example of the algorithm.

The article contains the comparative results of the experimental and calculated research of the strength of a pipeline with such defects as “metal loss” and “dent with groove”. Two coils with diameter of 820 mm and the thickness of 9 mm of 19G steel were used for full-scale pipe sample production. One of the coils was intentionally damaged by machining, which resulted in “metal loss” defect, the other one was dented (by press machine) and got groove mark (by chisel). The testing of pipe samples was performed by applying static internal pressure to the moment of collapse. The calculation of deterioration pressure was carried out with the use of national and foreign methodical approaches. The calculated values of collapsing pressure for the pipe with loss of metal mainly coincided with the calculation experiment results based on Russian method and ASME B31G. In case of pipe with dent and groove the calculated value of collapsing pressure demonstrated greater coincidence with Russian method and to a lesser extent with API 579/ASME FFS-1. In whole, all calculation methods demonstrate sufficient stability of results, which provides reliable operation of pipelines with defects.

The metal welding is accompanied by the formation of mechanically non-homogenous sections of welded connection. The pipeline welded connections also have sections, which are different in structure, chemical composition and mechanical properties. The mechanical inhomogeneity affects the load bearing capacity of welded connection and the structure as a whole, which is necessary to take into consideration when performing calculation analysis. So far, the specialists have established the dependencies in assessment of welded connection strength with various types of heterogeneous sections. However, this phenomenon has received little attention in case of pipeline welded connections made of low carbon steels. The existing theoretical models do not reflect actual anisotropy of mechanical properties of the welded connections and weld adjacent zone. The present study considers the model of welded connections of K56 pipe steels with various strength characteristics of sections of welded seam and weld adjacent zone, without defects. The assessment of mechanical inhomogeneity influence on load bearing capacity of welded connections was performed by applying the finite-element modelling of its stress-strain state. The developed numerical model helps to determine and optimize the criteria of testing of full scale samples of pipe steel welded connections with regards to the implementation of local strengthening effect. The research results demonstrated that the degree of contact strengthening in welded connections with X-shape grooving is higher than in welded connections with V-shaped grooving by 8 % at similar relative thickness of soft interlayer. The suggested numerical model can be applied for detailed calculations of pipelines with regards to the mechanical inhomogeneity of its welded connections.

The article presents defined scientific basis for planning repair-recovery works on trunk oil and gas pipelines, based on obtaining data about technical condition of pipelines and joined analysis of reliability indicators, safety and risk indicators with regards to material and technical opportunities of operating company and strategic characteristics of facilities. The article contains consolidated scientific opinion about the methods for planning repair-recovery activities on pipelines of Russia, USA and Europe. It is noted, that the approaches, implemented in real life, can differ from scientific basis due to a variety of causes. On the basis of the outlined concept, the analysis of practical approaches, applied for planning of overhauls of trunk gas and oil pipelines in Russia, was performed. The specialists use high technology analytical system to initiate remedial measures, focusing on reliability parameters and considering economic feasibility. However, what we consider promising is the extension of organizational and technical basis with the purpose of obtaining volume of statistic and actual source data, necessary for expert assessment. The planning of replacement of trunk pipeline sections is based on the results of continuous monitoring of the technical condition of the pipes by smart pigging and the involving into calculation both actual parameters of facilities operation and actual mechanical characteristics of pipe metals and welded connections, considering overall influence of specific production technology, steel work quality and service life length. With the purpose of further developing this approach, it is practical to extend the list of considered defect parameters and the use of the whole system of the pipeline technical condition data by adding the quantity of hours in service up to the failure in a probable scenario. The author stated the primary directions of developing methodical approaches to arranging the technical maintenance and repair of oil and gas pipeline for long-term operation.

This article is devoted to the search for optimal conditions for environmental and economic security of oil main pipelines using classical calculus of variations. The goal functions here are either stochastic reliability criteria for deterministic parametric criteria, or parametric criteria for specified reliability criteria. The functions of the optimization process are environmental and technological indicators of the system, taking into account the characteristics of oil pipelines or a set of measures to improve their reliability. The arguments are environmental and economic indicators that reflect the impact of control actions on the state of the environment and on the level of costs for the implementation of proposals. The formulation and study of the variational problem showed that only the introduction of environmental technologies and structures can minimize the cost of ensuring the safety of the impact of oil main pipelines on the host ecosystem.

When deploying a temporary fuel storage warehouse, the primary source of soil contamination by oil products is technological losses related to the leakage of isolation valves. To protect the soil from contamination, containers are placed on a layer of sand. The thickness of the sand layer depends on the volume of possible losses. The purpose of the work is to model the depth of diesel fuel penetration into the protective layer of sand bed. The method of performing the experiment imitated a high rate of fuel penetration in the form of droplets onto the protective layer. The article considers the mechanism of fuel penetration into sand and factors, determining the penetration depth. It is established that the mechanism of fuel penetration into the protective layer has two stages, on each of which the penetration depth and rate of fuel distribution are different. The maximum penetration depth is reached on the first stage and depends on the quantity of fuel. The author developed the model, which allows the determination of the thickness of the sand bed protective layer with known granulometric particle composition necessary for the prevention of diesel fuel penetration into soil.

The author considers the new approaches to the rating system (labor complexity evaluation) of directors and specialists of the production and structural subdivisions of Transneft system entities, based on the results of independent expert and analytical evaluation of a universal set of production and technical values, representing the subdivisions’ activities. The author performed a number of practical studies and developments in the area of forming universal mathematical models, which allow economic analysis to be carried out and establishing a justified salary as per the positions of the directors of various subdivisions, regardless of activity type and level of position. The article introduces universal systems of point-based and factor-based ranking, based on the use of innovative mathematical analysis methods (multi-innovating normalizing, decision matrices, hierarchy analysis) for obtaining normalized assessment of production activity), administrative work load and professional labor complexity. The devised analytical approaches to the selection and assessment of the performance of subdivisions provide the possibility for objective and independent calculation for rating determination (salary) both for the Transneft system as a whole and for separate structural subdivisions (observing labor laws). The represented methods have significant applicability in modern conditions – on the stage of transition to the new system of professional standards and evaluation of qualifications, as well as the rejection of traditional models, based on strict attachment to the rating and qualification system, fixed salaries, etc.
