    Superposition rules for higher-order systems and their applications

    Full text link
    Superposition rules form a class of functions that describe general solutions of systems of first-order ordinary differential equations in terms of generic families of particular solutions and certain constants. In this work we extend this notion and other related ones to systems of higher-order differential equations and analyse their properties. Several results concerning the existence of various types of superposition rules for higher-order systems are proved and illustrated with examples extracted from the physics and mathematics literature. In particular, two new superposition rules for second- and third-order Kummer--Schwarz equations are derived.Comment: (v2) 33 pages, some typos corrected, added some references and minor commentarie

    Bronchial complications are among the main causes of impairing postoperative period and thansplant failure. Severe bronchial complications are very rare but have a high mortality rate. Light forms decrease transplant function and while progressing can leads to life-threatening conditions without required treatment. Nowadays there is a huge necessity in classification of diagnostic and bronchial complications treatment on different terms after lung transplantation. Methods of observation bronchoscopy and interventional bronchology are allowing us to realize prevention, diagnostic and treatment bronchial complications.Π‘Ρ€ΠΎΠ½Ρ…ΠΈΠ°Π»ΡŒΠ½Ρ‹Π΅ ослоТнСния ΡΠ²Π»ΡΡŽΡ‚ΡΡ ΠΎΠ΄Π½ΠΎΠΉ ΠΈΠ· основных ΠΏΡ€ΠΈΡ‡ΠΈΠ½ тяТСлого тСчСния послСопСрационного ΠΏΠ΅Ρ€ΠΈΠΎΠ΄Π° ΠΈ нСблагоприятных исходов Ρƒ Ρ€Π΅Ρ†ΠΈΠΏΠΈΠ΅Π½Ρ‚ΠΎΠ² донорских Π»Π΅Π³ΠΊΠΈΡ….

    Treatment and rehabilitation of patients with cancer of the larynx is a complex issue, as the majority of patients (60-70%) are diagnosed at the III and IV stages of the disease. The main type of surgery is a laryngectomy which leads to organ dysfunction and disability. It is known that in cases of locally advanced laryngeal tumors resection may be performed. However, after these operations from 22 to 57% of patients couldn’t be rehabilitated due to the difficulty in creating of sufficient lumen of the larynx, development of chondroperihondritis, growth of granulation tissue, fibrosis formation and stenosis of the larynx (Bukhman L.A., 1982; Bityutskij P.T., 1990; Park H.Y., 2009; SoYeonLimatal, 2012).Π›Π΅Ρ‡Π΅Π½ΠΈΠ΅ ΠΈ рСабилитация Π±ΠΎΠ»ΡŒΠ½Ρ‹Ρ… Ρ€Π°ΠΊΠΎΠΌ Π³ΠΎΡ€Ρ‚Π°Π½ΠΈ являСтся слоТной ΠΏΡ€ΠΎΠ±Π»Π΅ΠΌΠΎΠΉ, Ρ‚Π°ΠΊ ΠΊΠ°ΠΊ Π±ΠΎΠ»ΡŒΡˆΠΈΠ½ΡΡ‚Π²ΠΎ Π±ΠΎΠ»ΡŒΠ½Ρ‹Ρ… (60–70%) ΠΏΠΎΡΡ‚ΡƒΠΏΠ°ΡŽΡ‚ Π½Π° Π»Π΅Ρ‡Π΅Π½ΠΈΠ΅ Π² 3 ΠΈ 4 стадиях заболСвания.

    Objective: to evaluate the expression levels of miRNA (miR-27, miR-101, miR-142, miR-339 and miR-424) and its relationship with clinical and laboratory parameters in lung transplant recipients. Materials and methods. The study included 57 lung recipients aged 10 to 74 years (35 Β± 15), including six children (9%) – four boys 10, 12, 13 and 17 years and girls 13 and 14 years old – and 51 adult recipients, including 30 men (62.5%). The control group was made up of 14 healthy individuals that were not significantly different by gender and age. Expression levels of the microRNAs studied in blood plasma were determined via quantitative polymerase chain reaction (PCR). Correlations of miRNA expression levels with complete blood count and biochemical blood test indicators were analyzed. Results. Patients with end-stage chronic respiratory failure (potential lung recipients) were found to have significantly higher expression levels of miR-27, miR-101 and miR-339 in plasma than the healthy individuals (p = 0.02, p = 0.03 and p = 0.01, respectively). The expression level of miR-339 correlated with the age of potential lung recipients (p = 0.04). It was a negative correlation (r = –0.46). The expression levels of the other four miRNAs were age independent. The average expression level of miR-424 in lung recipients in the long-term period after lung transplant was higher than in waitlisted patients (p = 0.03). Analysis of the relationship between miRNA expression levels and external respiration function in the long-term post-transplant period showed that miR-142 expression level (r = 0.61; p = 0.04) positively correlates with the Tiffeneau-Pinelli index. This strong correlation, which exceeds 85%, indicates the presence of restrictive lung diseases. A year and more after transplantation, it was found that in the recipients, there were close positive correlations between miR-27, miR-142, miR-424 expression levels and blood leukocyte concentration, as well as between the miR-142 expression level and the sCD40L concentration during this period. Conclusion. A comparative study of the expression level of miRNAs (miR-27, miR-101, miR-142, miR-339 and miR-424) in the blood plasma of patients suffering from end-stage chronic lung diseases of various origin and in lung recipients enables us to conclude that further studies of the miRNA panels are needed in order to assess their effectiveness as potential molecular and genetic markers of post-transplant complications.ЦСль: ΠΎΡ†Π΅Π½ΠΈΡ‚ΡŒ ΡƒΡ€ΠΎΠ²Π΅Π½ΡŒ экспрСссии ΠΌΠΈΠΊΡ€ΠΎΠ ΠΠš (miR-27, miR-101, miR-142, miR-339 ΠΈ miR-424) ΠΈ Π΅Π΅ связь с клиничСскими ΠΈ Π»Π°Π±ΠΎΡ€Π°Ρ‚ΠΎΡ€Π½Ρ‹ΠΌΠΈ ΠΏΠ°Ρ€Π°ΠΌΠ΅Ρ‚Ρ€Π°ΠΌΠΈ Ρƒ Ρ€Π΅Ρ†ΠΈΠΏΠΈΠ΅Π½Ρ‚ΠΎΠ² трансплантированных Π»Π΅Π³ΠΊΠΈΡ….

    Bronchial complications, along with development and progression of chronic dysfunction on the background of chronic rejection, are factors that reduce the quality and life of lung and heart-lung recipients. They also increase the frequency of hospitalizations. Application of cryotechnology is based on the contact effect of extremely low temperatures on organs and tissues using a cryoprobe.

Due to the variety of diseases causing patients to resort to lung transplant surgeries,Β there is a wide range of different complications and conditions that are subject to an individual clinical approachΒ to determine treatment tactics. Each case is of great clinical interest due to the small amount of these operationsΒ and the complexity of postoperative rehabilitation, which requires a multidisciplinary approach [12].

    Open laryngectomy: Clinical experience

    No full text
    Introduction. The problem of treatment and rehabilitation of patients with laryngeal cancer has been a complicated and controversial one.Important conditions for selection of the type and scale of functionally sparing surgical intervention are accurate preoperative diagnosis of advancement of the tumor and oncological appropriateness of the intervention. Currently, the problem of single-step reconstruction of lost laryngeal functions after organ-preserving surgeries remains open. For this purpose, researchers use both auto-/homografts and endoprosthetics made of various materials. In some cases, endoprosthetics in lyrengectomy didn’t allow to restore laryngeal lumen due to granulation tissue, cicatricial stenosis, laryngotracheomalacia.The study objective is to increase treatment and rehabilitation effectiveness in patients with laryngeal cancer after open laryngectomy.Materials and methods. Our experience is based on open laryngectomies in 86 patients performed at the Clinical Oncology Dispensary No. 1 of the Moscow Healthcare Department in the period from 2011 to 2014. Primary laryngeal cancer was diagnosed in 84 (97.7 %) patients, recurrent laryngeal cancer after a full course of radiation therapy – in 2 (2.3 %) patients. Vertical laryngectomy was performed in 74 patients, horizontal – in 12 patients.Vertical laryngectomies were performed for tumors located near the vocal and vestibular flaps, anterior commissure, subglottis, laryngeal sinus;horizontal for tumors located near the epiglottis, vestibular flaps, vallecula, root of the tongue if arytenoids were intact and vocal cords were mobile. In the postoperative period, an important factor was restoration of the organ’s function through early rehabilitation of respiratory, vocal, and protective functions. Evaluation of the laryngeal lumen was performed using endoscopic examination. Any diagnosed ligatures, granulation tissue, scars were resected. Prior to decannulation, ultrasound examination of the larynx was performed. Effectiveness of vocal function restoration was evaluated using computer acoustic analysis of the voice.Results. Restoration of the lost laryngeal functions after organ-preserving open laryngectomies in patients with laryngeal cancer is achieved through reconstruction of the remaining parts of the organ, formation of an adequate lumen for breathing through postoperative endoscopic correction, and early rehabilitation of respiratory, vocal, and protective function.Conclusion. Open laryngectomies with restoration of the remaining parts and single-step reconstruction of the lumen with an endoprosthesis, as well as subsequent combined treatment, allowed to restore respiratory function in 93.1 % patients, vocal function – in 91.9 % patients
