The use of wound dressings is gaining more and more popularity, especially in the field of tactical and military medicine. Developing wound dressings capable of facilitating wound treatment and reducing healing time is one of the challenges of modern science. So, sodium alginate (Alg) is a good candidate for the development of wound dressings due to its bio- and hemocompatibility and biodegradability. However, Alg has its shortcomings, which can be dispatched by modification. The purpose of this work was to investigate the effect of Alg modification on the kinetics of ethonium release from crosslinked with Ca
2+ ions samples. For this purpose, a method of Alg modifying with octane-1-amine was developed without the use of organic solvents and with the use of 1-ethyl-3-(3-dimethyl aminopropyl) carbodiimide hydrochloride (EDCl) as an initiator. The optimal parameters of alginate modification process were defined as 60 °С temperature and 24 hours duration. Physicochemical methods confirmed the success of the modification. Films based on the alginate modified with octane-1-amine (AlgM) were obtained using a calcium chloride solution as a crosslinker. The kinetics of swelling was studied and we found that the degree of swelling of the sample based on AlgM after 10 minutes is twice as large (α = 0.71) as for Alg (α = 0.37), which indicates a faster release of drugs. It has been found that the kinetics of release of ethonium depends not only on the kinetics of swelling but also on the chemical nature of the drug. The ethonium was immobilised in alginate films as a model of bactericidal drug. The kinetics of ethonium release was studied at different pH values corresponding to the pH of healthy skin (5.5), open wounds (7.2) and inflamed wounds (8.2). It was found that the release of ethonium from the sample based on AlgM is more pH-sensitive and prolonged, compared to the sample based on Alg. This effect is explained by the appearance of an additional mechanism of retention of ethonium by AlgM due to hydrophobic-hydrophobic interactions in the films. The prolonged release properties observed in the drug-loaded samples make them promising candidates for the development of targeted drug delivery systems and wound dressings, which are particularly relevant for the treatment of chronic and burn wounds. Future research will focus on optimizing the crosslinking method and exploring potential applications of modified alginate-based materials in biomedical sciences. [ABSTRACT FROM AUTHOR]- Published

BACKGROUND: Type 2 diabetes mellitus is the leading cause of kidney failure worldwide, but few effective long-term treatments are available. In cardiovascular trials of inhibitors of sodium-glucose cotransporter 2 (SGLT2), exploratory results have suggested that such drugs may improve renal outcomes in patients with type 2 diabetes. METHODS: In this double-blind, randomized trial, we assigned patients with type 2 diabetes and albuminuric chronic kidney disease to receive canagliflozin, an oral SGLT2 inhibitor, at a dose of 100 mg daily or placebo. All the patients had an estimated glomerular filtration rate (GFR) of 30 to 300 to 5000) and were treated with renin-angiotensin system blockade. The primary outcome was a composite of end-stage kidney disease (dialysis, transplantation, or a sustained estimated GFR of

The adhesive properties of composite coatings based on poly (m-, p-phenylene isophtalamide) with widely used antifriction fillers (copper phthalocyanine, molybdenum disulfide, graphite and boron nitride) were investigated. The results of measurements of adhesive characteristics are obtained by means of cross cutting test and quantitative peel test. Introduction of fillers leads to an increase in the adhesive strength of coatings, while the type of a filler virtually does not affect the adhesive properties. When the filler content is 20 wt.% and more, the cohesive fracture of the coating occurs during the peel test. Introduction of the fillers significantly reduces the value of internal stresses that is accompanied by an increase in the adhesion strength. By way of example of graphite, we showed that an increase in the particle dispersion of the filler results in an increase in the value of adhesion strength of composite coatings, but does not cause any fundamental changes in the character of the dependence of adhesion strength on the filler concentration.

- Abstract
Неспроможність анастомозу — одне з найсерйозніших ускладнень в абдомінальній хірургії. Це ускладнення є основною причиною смерті пацієнтів у хірургії колоректального раку. При цьому вирішення питання про методи профілактики неспроможності колоректального анастомозу є актуальним напрямком в сучасній онкоколопроктології. За різними даними, частота неспроможності анастомозу при раку товстого кишківника становить 3 — 7 %, при раку прямої кишки — 13 — 18 %, при цьому післяопераційна летальність варіює від 1до 27 %. Розкид даних щодо частоти неспроможності анастомозу та летальності внаслідок цього ускладнення можуть бути зумовлені різними чинниками, зокрема неоднорідністю груп пацієнтів, залучених у дослідження, відмінностями в хірургічній техніці й періопераційному веденні хворих, різним визначенням неспроможності анастомозу. Це ускладнення є незалежним предиктором погіршення загальної та канцер‑специфічної виживаності. Ризик розвитку неспроможності може бути зумовлений функціональним статусом хворого, характером захворювання, видом хірургічного втручання та іншими чинниками. Стратифікація пацієнтів за чинниками ризику розвитку неспроможності анастомозу дає змогу прогнозувати виникнення цього ускладнення і визначити оптимальну тактику лікування в конкретному випадку. Рання діагностика неспроможності анастомозу має вирішальне значення для успішного результату лікування та зниження показників летальності. Нині не існує загальновизнаних, стандартизованих і ефективних періопераційних чинників ризику розвитку цього ускладнення. Актуальним є пошук оптимальної тактики діагностики та лікування неспроможності анастомозу., Несостоятельность анастомоза — одно из наиболее серьезных осложнений в абдоминальной хирургии. Данное осложнение является основной причиной смерти пациентов в хирургии колоректального рака. При этом решение вопроса о методах профилактики несостоятельности колоректального анастомоза является актуальным направлением в современной онкоколопроктологии. По разным данным, частота несостоятельности анастомоза при раке толстого кишечника составляет 3 — 7 %, при раке прямой кишки — 13 — 18 %, при этом послеоперационная летальность варьирует от 1 до 27 %. Разброс данных о частоте несостоятельности анастомоза и летальности вследствие данного осложнения могут быть обусловлены разными факторами, в частности неоднородностью групп пациентов, включенных в исследования, различиями в хирургической технике и периоперационном ведении больных, разным определением несостоятельности анастомоза. Данное осложнение является независимым предиктором ухудшения общей и опухоль‑специфической выживаемости. Риск развития несостоятельности может быть обусловлен функциональным статусом больного, характером заболевания, видом хирургического вмешательства и другими факторами. Стратификация пациентов по факторам риска развития несостоятельности анастомоза позволяет прогнозировать возникновение данного осложнения и определить оптимальную тактику лечения в конкретном случае. Ранняя диагностика несостоятельности анастомоза имеет решающее значение для благоприятного исхода лечения и уменьшения показателей летальности. На сегодняшний день не существует общепризнанных, стандартизированных и эффективных периоперационных факторов риска развития данного осложнения. Актуальным является поиск оптимальной тактики диагностики и лечения несостоятельности анастомоза., The anastomotic failure is one of the most serious complications in abdominal surgery. This complication is the leading cause of death for patients after colorectal cancer surgery. At the same time, decision of the question of suture failure methods prevention of the colorectal anastomosis is an important trend in modern oncocoloproctology. According to some publication, anastomotic failure after colon cancer surgery ranges from 3 — 7 % of cases, rectal cancer — 13 — 18 %, while the rates of postoperative mortality vary within 1 — 27 %. The variation in failure and mortality rates from this complication may be due to a variety of factors, including heterogeneity of the patient groups included in the study, differences in the surgical technique and perioperative patient administration, and various definitions of anastomotic failure. This complication is an independent predictor of increased overall and cancer‑specific survival. The risk of leakage may be due to the functional status of the patient, the nature of the disease, the type of surgical intervention and other factors. Stratification of patients according to risk factors for the development of anastomotic leakage makes it possible to predict the occurrence of this complication and to determine the optimal treatment strategy in each particular case. Early diagnosis of anastomotic leakage is critical for a favorable treatment outcome and a reduction in mortality rates. There are not generally accepted, standardized and effective perioperative risk factors for the development of this complication. The search of the optimal tactics for the diagnosis and treatment of anastomotic failure remains relevant.

Today, esophageal cancer (EC) remains a complex oncological problem.Aim of the work is to assess the survival rates of patients with the I–III stages esophageal cancer and esophagogastric junction.Materials and methods. 50 patients with the I-III stages EC and esophagogastric junction cancer were operated in the Thoracic Surgery Department of Municipal Institution “Zaporizhzhia Regional Clinical Oncology Dispensary” for the period from 2010 to 2017. The Ivor–Lewis surgery was an operation of choice.Results. While survival analysis it was noted that the 5-year overall survival rate among operated patients was 40.3 %, median survival made 21.0 months. In the patients with the I–II stages median survival time wasn't reached (more than 50.0 % of patients survived a 5-year follow-up period) and the 5-year overall survival rate made 50.9 % (P < 0.05), while in patients with the III stage median survival time made 13.0 months (P < 0.05).Conclusions. The results of the surgical treatment of patients with EC and esophagogastric junction of the I–III stages in the Thoracic Surgery Department of Municipal Institution “Zaporizhzhia Regional Clinical Oncology Dispensary” did not differ from the overall results of this issue studies. At the same time acceptable indications of postoperative complications, mortality and overall survival have been reached., До настоящего времени рак пищевода (РП) остается актуальной проблемой онкологии.Цель работы – оценить показатели выживаемости у пациентов с раком пищевода и пищеводно-желудочного перехода I–III стадий.Материалы и методы. За период с 2010 по 2017 г. в торакальном отделении КУ «Запорожский областной клинический онкологический диспансер» прооперировано 50 пациентов с РП и раком пищеводно-желудочного перехода I–III стадий. Операция Айвора–Льюиса была операцией выбора.Результаты. При анализе выживаемости отмечено, что общая 5-летняя выживаемость прооперированных пациентов составила 40,3 %, медиана выживаемости – 21,0 месяц. У пациентов с I–II стадиями медиана выживаемости не достигнута (более 50,0 % пациентов пережили 5-летний период наблюдения), общая 5-летняя выживаемость при этом составила 50,9 % (р < 0,05), у пациентов с III стадией медиана выживаемости составила 13,0 месяцев (р < 0,05).Выводы. Результаты хирургического лечения пациентов с РП и пищеводно-желудочного перехода I–III стадии не отличались от данных, полученных в других исследованиях. Достигнуты приемлемые показатели послеоперационных осложнений и летальности, общей выживаемости., Рак стравоходу (РС) донині залишається складною проблемою онкології.Мета роботи – оцінити показники виживаності пацієнтів із раком стравоходу та стравохідно-шлункового переходу I–III стадій.Матеріали та методи. За період з 2010 до 2017 р. у торакальному відділенні КУ «Запорізький обласний клінічний онкологічний диспансер» прооперували 50 пацієнтів із РС і раком стравохідно-шлункового переходу I–III стадій. Операція Айвора–Льюїса була операцією вибору.Результати. Під час аналізу виживаності визначили, що загальна 5-річна виживаність прооперованих пацієнтів дорівнювала 40,3 %, медіана виживаності – 21,0 місяць. У пацієнтів з I–II стадіями медіана виживаності не досягнута (понад 50,0 % пацієнтів пережили 5-річний період спостереження), загальна 5-річна виживаність дорівнювала 50,9 % (р < 0,05), а в пацієнтів з III стадією медіана виживаності становила 13,0 місяців (р < 0,05).Висновки. Результати хірургічного лікування пацієнтів із РС і стравохідно-шлункового переходу I–III стадій не відрізнялися від даних, що одержали інші дослідники. Отримали прийнятні показники післяопераційних ускладнень і летальності, загальної виживаності.

Objective — to study psychological status of adolescents.Material and methods. We observed 82 children, mean age 14 years old, with 48.94% boys and 51.06% girls. We provided questionnaires for evaluation and correlation of psychological and somatical conditions. The methods included: a questionnaire assessing health and wellbeing of pupils, the standardize scale «Termometr», a mood evaluation test, assessing of the school related anxiety by using Phillip and Spielberg tests. We also assessed influence of families on study subjects by providing the Varga-Stolin test of parental attitude to their child. Teachers were provided questionnaire «Stott's Map of Observation».Results. Among all observed children 72% showed moderate and high personality related anxiety, 91% of whom were ready to react aggressively on certain situations; 42% of observed had fear before knowledge assessment, 39% felt fear of self-expression, 30% fear in a student-teacher relationship; 16% admitted feeling unwell, 21% noticed decreased activity, 11% had depressed mood. Overall 48% showed signs of depression; 29% showed evidence of developing maladaptive disorder. When interwiewing parents, it was established that significant number of adults behave authoritatively towards their children, had strict rules and disciplinary frames, almost always impose their will or, conversely, the control of the child's actions was practically absent. Majority of the parents experienced negative emotions towards their own child: irritation, «hate», «fury», and condescension, consider their children of no prospects, lack of optimistic outlook, do not believe in their future, had low estimation of their abilities. Close to 25% of parents thought that their children were burden for them and their careers. Over 40% adolescent from full families felt «family deprivation». According to the teachers' observation, 78% of adolescents displayed signs of disadaptation.Conclusions. Using the proposed «three axes» approaches (sociological—pedagogic, psychological, and medical) creates the possibility to stratify general risk factors prior to manifestation of disorders and to carry out preventive and rehabilitation measures., Цель — изучить психологическое состояние подростков.Пациенты и методы. Обследованы 82 подростка. Средний возраст — 14 лет. Мальчики — 48,94%, девочки — 51,06%. С целью оценки психологического и соматического здоровья подростков проведено анкетирование и заполнение общепринятых шкал. Использованы анкета оценки состояния здоровья школьника, шкала «Термометр», тест оценки настроения, тест школьной тревожности Филипса и тест Спилберга. С целью исследования характера влияния семьи на ребенка проведено тестирование родителей с помощью теста Барга—Столина. Преподавателям предложен опросник «Карта наблюдений Стотта».Результаты. При опросе детей установлено, что у 72% сформирована умеренная и высокая личностная тревожность, на фоне которой до 91% готовы бурно отреагировать на событие, 42% — ощущать страх во время проверки знаний, 39% указывали на страх самовыражения, 30% — на страхи и проблемы в отношениях с педагогами, 16% — на снижение самочувствия, 21% — на сниженную активность, 11% — на сниженное настроение, что в совокупности (48%), с высокой достоверностью, указывает на признаки депрессии, у 29% детей происходит формирование дезадаптивных расстройств. При опросе родителей установлено, что взрослые ведут себя авторитарно по отношению к детям, создавая суровые дисциплинарные рамки, почти всегда навязывают свою волю или, наоборот, контроль над действиями ребенка практически отсутствует. Ощущают к детям, в общем, негативные чувства: раздражение, злость, ненависть, считают ребенка неудачником, не верят в его будущее, низко оценивают его способности. 25% родителей считают, что дети им «мешают» в жизни и в трудовой деятельности. 40% детей подросткового возраста из полных семей чувствуют семейную депривацию. По наблюдениям учителей, у 78% исследуемых подростков выявлены признаки дезадаптации.Выводы. Использование предложенного «трехосевого» подхода (социально-педагогического, психологического и медицинского) позволяет на доманифестном этапе заболевания выделить группу «зоны риска», провести лечебно-профилактические и реабилитационные мероприятия., Мета — вивчити психологічний стан підлітків.Пацієнти та методи. Обстежено 82 підлітки. Середній вік — 14 років. Хлопці — 48,94%, дівчата — 51,06%. З метою оцінки психологічного і соматичного здоров'я підлітків проведено анкетування та заповнення загальноприйнятих шкал. Використано анкету оцінки стану здоров'я школяра, шкалу «Термометр», тест оцінки настрою, тест шкільної тривожності Філіпса і тест Спілберга. З метою дослідження характеру впливу родини на дитину проведено тестування батьків за допомогою тесту Барга—Століна. Викладачам запропоновано опитувальник «Карта спостережень Стотта».Результати. При опитуванні дітей встановлено, що у 72% сформована помірна та висока особистісна тривожність, на тлі якої до 91% готові бурхливо відреагувати на подію; 42% — відчувати страх при перевірці знань, 39% вказували на страх самовираження, 30% — на страхи та проблеми у стосунках із педагогами; 16% — на погіршене самопочуття, 21% — на знижену активність, 11% — на знижений настрій, що в сукупності (48%), з високою вірогідністю, вказує на ознаки депресії; у 29% дітей відбувається формування дезадаптивних розладів. При опитуванні батьків встановлено, що дорослі поводяться авторитарно щодо власних дітей, створюючи суворі дисциплінарні рамки, майже завжди нав'язують свою волю або, навпаки, контроль над діями дитини практично відсутній. Відчувають до дитини загалом негативні почуття: роздратованість, злість, ненависть, вважають дитину невдахою, не вірять в її майбутнє, низько оцінюють її здібності. 25% батьків вважають, що діти їм «заважають» у житті і трудовій діяльності. 40% дітей підліткового віку з повних сімей відчувають сімейну депривацію. За спостереженням учителів, у 78% досліджуваних підлітків виявлено ознаки дезадаптації.Висновки. Використання запропонованого «тривісьового» підходу (соціально-педагогічного, психологічного та медичного) створює можливість на доманіфестному етапі захворювання виділити групу «зони ризику», провести лікувально-профілактичні та реабілітаційні заходи.

Despite rapid development of medicine, acute pancreatitis (AP) is still a problem.Aim. To evaluate pathological changes of retroperitoneal space (RS), the results of ultrasound research, computed tomography and laparoscopy were studied in 62 patients with severe form of AP.Methods and results. Our own improved division of retroperitoneal space was used during work. It was based on already existing classification and it’s simple and can be used in everyday practice.It was revealed that infiltrative changes of RS develop more often in patients with edematous form of disease. In patients with necrotic form infiltrative changes as well as liquid ones can develop in the RS. The more extensive is pancreas necrosis, the higher is the probability that greater number of anatomic areas will be involved into the pathological process. It was noticed that complications appear more often in patients with liquid changes in the RS as well as they have higher percentage of mortality.Conclusion. Thereby, dynamic observation of area and depth of pathological process spreading, its condition allows deciding on correct treatment strategy., Острый панкреатит остается проблемной патологией. С целью оценки патологических изменений в забрюшинном пространстве изучены данные ультразвукового исследования, компьютерной томографии, лапароскопии у 62 пациентов с тяжелым течением острого панкреатита. Использовали собственное усовершенствованное деление забрюшинного пространства. Установлено, что у пациентов с отечной формой острого панкреатита чаще всего развиваются инфильтративные изменения тканей забрюшинного пространства; у пациентов с некротической формой могут возникать как инфильтративные, так и жидкостные изменения. Чем больше объем некроза поджелудочной железы, тем выше вероятность вовлечения в патологический процесс большего количества анатомических областей. У больных с жидкостными изменениями в забрюшинном пространстве чаще возникают осложнения, а также выше процент летальности. Это свидетельствует, что динамическое наблюдение за площадью, глубиной распространения патологического процесса и его состоянием позволяет правильно выбирать лечебную тактику., Гострий панкреатит залишається проблемною патологією. З метою оцінювання патологічних змін у заочеревинному просторі вивчили результати ультразвукового дослідження, комп’ютерної томографії, лапароскопії у 62 хворих із тяжким перебігом гострого панкреатиту. Застосовували власний вдосконалений поділ заочеревинного простору. Виявили, що в пацієнтів із набряковою формою захворювання частіше розвиваються інфільтративні зміни тканин у заочеревинному просторі; в пацієнтів із некротичною формою можуть виникати як інфільтративні, так і рідинні зміни. Чим більший об’єм некрозу підшлункової залози, тим вища ймовірність залучення в патологічний процес більшої кількості анатомічних ділянок. У хворих із рідинними змінами в заочеревинному просторі частіше виникають ускладнення, а також більший відсоток летальності. Це свідчить, що динамічне спостереження за площею, глибиною поширення патологічного процесу та його станом дає можливість правильно обрати лікувальну тактику.

- Abstract
Gastric cancer remains one of the most interesting problem of the oncology. Combined approach is recommended for treatment of gastric cancer patients and it use almost in all countries of the world. The role of adjuvant chemotherapy for patients with gastric cancer discusses since the mid of XX century.Aim. This critical review consider the basic clinical research on this issue. It was found that the results of studies from theUSand European countries differ significantly from the results obtained in the works from Japan and Korea. According to clinical studies, adjuvant chemotherapy has demonstrated its efficacy only in patients 'eastern' population with a D2 lymph node dissection. At the same time, this chemotherapy regimen was not effective in patients of 'Western' populations. In this case, most of the works from the US and Europe had limited volume of lymph node dissection.Conclusion. It is very important to start new investigations for studying the role of adjuvant chemotherapy for patients from «west» region after radical operation with D2 lymph node dissection., Лечение рака желудка остаётся актуальным вопросом онкологии. С целью улучшения результатов практически во всех странах мира рекомендован комбинированный подход к лечению этого заболевания. С середины XX века активно изучается роль адъювантной химиотерапии. В нашем критическом обзоре представлены базовые клинические исследования, посвящённые данной проблеме. Было выяснено, что результаты научных работ, проведённых в США и странах Европы, существенно отличаются от результатов, полученных в Японии и Корее. По данным клинических исследований, адъювантная химиотерапия показала свою эффективность только у пациентов «восточной» популяции с объёмом лимфодиссекции D2. В то же время у пациентов «западной» популяции этот режим химиотерапии оказался неэффективным. При этом в большей части работ из США и стран Европы выполнялся ограниченный объём лимфодиссекции, который в настоящее время является неприемлемым при хирургическом лечении пациентов с резектабельным раком желудка. Актуальным остаётся проведение клинических исследований, посвящённых изучению эффективности адъювантной химиотерапии у пациентов «западного» региона после радикальной операции с D2 лимфодиссекцией., Лікування раку шлунка залишається актуальним питанням онкології. З метою поліпшення результатів лікування раку шлунка комбінований підхід рекомендований практично в усіх країнах світу. Із середини XX століття активно вивчається роль ад’ювантної хіміотерапії під час лікування цього захворювання. У нашому критичному огляді висвітлили базові клінічні дослідження, котрі присвячені цій проблемі. Встановили, що результати досліджень науковців із США і країн Європи суттєво відрізняються від результатів, що отримали вчені Японії та Кореї. За даними клінічних досліджень, ад’ювантна хіміотерапія показала свою ефективність тільки в пацієнтів «східної» популяції з об’ємом лімфодисекціі D2. У пацієнтів «західної» популяції цей режим хіміотерапії виявився неефективним. При цьому в більшій частині робіт із США і країн Європи виконувався обмежений обсяг лімфодисекціі, який натепер є неприйнятним при хірургічному лікуванні пацієнтів із резектабельним раком шлунка. На підставі аналізу визначили, що актуальним залишається вивчення ефективності ад’ювантної хіміотерапії в пацієнтів «західного» регіону після радикальної операції з D2 лімфодисекцією.

- Abstract
Despite rapid development of medicine, acute pancreatitis (AP) is still a problem.Aim. To evaluate pathological changes of retroperitoneal space (RS), the results of ultrasound research, computed tomography and laparoscopy were studied in 62 patients with severe form of AP.Methods and results. Our own improved division of retroperitoneal space was used during work. It was based on already existing classification and it’s simple and can be used in everyday practice.It was revealed that infiltrative changes of RS develop more often in patients with edematous form of disease. In patients with necrotic form infiltrative changes as well as liquid ones can develop in the RS. The more extensive is pancreas necrosis, the higher is the probability that greater number of anatomic areas will be involved into the pathological process. It was noticed that complications appear more often in patients with liquid changes in the RS as well as they have higher percentage of mortality.Conclusion. Thereby, dynamic observation of area and depth of pathological process spreading, its condition allows deciding on correct treatment strategy., Острый панкреатит остается проблемной патологией. С целью оценки патологических изменений в забрюшинном пространстве изучены данные ультразвукового исследования, компьютерной томографии, лапароскопии у 62 пациентов с тяжелым течением острого панкреатита. Использовали собственное усовершенствованное деление забрюшинного пространства. Установлено, что у пациентов с отечной формой острого панкреатита чаще всего развиваются инфильтративные изменения тканей забрюшинного пространства; у пациентов с некротической формой могут возникать как инфильтративные, так и жидкостные изменения. Чем больше объем некроза поджелудочной железы, тем выше вероятность вовлечения в патологический процесс большего количества анатомических областей. У больных с жидкостными изменениями в забрюшинном пространстве чаще возникают осложнения, а также выше процент летальности. Это свидетельствует, что динамическое наблюдение за площадью, глубиной распространения патологического процесса и его состоянием позволяет правильно выбирать лечебную тактику., Гострий панкреатит залишається проблемною патологією. З метою оцінювання патологічних змін у заочеревинному просторі вивчили результати ультразвукового дослідження, комп’ютерної томографії, лапароскопії у 62 хворих із тяжким перебігом гострого панкреатиту. Застосовували власний вдосконалений поділ заочеревинного простору. Виявили, що в пацієнтів із набряковою формою захворювання частіше розвиваються інфільтративні зміни тканин у заочеревинному просторі; в пацієнтів із некротичною формою можуть виникати як інфільтративні, так і рідинні зміни. Чим більший об’єм некрозу підшлункової залози, тим вища ймовірність залучення в патологічний процес більшої кількості анатомічних ділянок. У хворих із рідинними змінами в заочеревинному просторі частіше виникають ускладнення, а також більший відсоток летальності. Це свідчить, що динамічне спостереження за площею, глибиною поширення патологічного процесу та його станом дає можливість правильно обрати лікувальну тактику.

Since about three decades, inhibitors of the renin-angiotensin system have been available in clinical practice. Although angiotensin-converting enzyme inhibitors (ACEi) and angiotensin II receptor blockers (ARB) were primarily aimed at treatment of hypertension and heart failure, more of their positive effects were discovered later on. Patients with chronic kidney disease were recognised to profit the most from treatment with these agents; however some blind spots are still present. Patients with advanced renal failure are almost always excluded from the trials; patients with end-stage renal disease form the least studied population of all and outcomes of treatment with ACEi/ARB are still uncertain in these cohorts. The aim of this review is to summarise and update the evidence about effects of All inhibitors in patients with chronic kidney disease with the specific emphasis on patients treated with dialysis. Lately a novel indication for ACEi/ARB administration, especially for peritoneal dialysis patients, has been proposed. It is based on the capacity of these drugs to inhibit the local tissue renin-angiotensin system, which results in less development of peritoneal fibrosis and a longer life for the peritoneal membrane. The most recent available data are presented in this review.

- Abstract
Background: Many studies have shown the renoprotective effect of angiotensin-converting enzyme inhibitors (ACEi) and angiotensin II receptor blockers (ARBs) in patients with chronic kidney disease stages I-IV. Two randomized controlled trials (RCTs) showed a positive effect of AII inhibitors on residual glomerular filtration rate (rGFR) in peritoneal dialysis (PD) patients. However, these studies were small and were performed in a highly selected group of PD patients. Our aim was to confirm the above findings in a larger number of prospectively followed PD patients., Methods: First we analyzed the time course of decline of rGFR in 452 incident PD patients that were not anuric at the start of dialysis and that had structured follow-up data, with measurements at 3, 6, 12, 18, 24, 30, and 36 months after the start of dialysis. Changes in rGFR over time were analyzed with a linear mixed model for repeated measures. In addition, Cox regression models were used to estimate the risk of developing anuria. In a second approach, we aimed to repeat the above analyses in a selected group of patients that theoretically could have been randomized and therefore resembled the population studied in the 2 mentioned RCTs. In this group the follow-up was restricted to 1 year., Results: 201 patients were treated with ACEi/ARBs and 251 did not take these drugs at the start of PD. More patients from the treated group had diabetes and used more antihypertensive medications. The time course of decline of rGFR was not different between the 2 groups over the 3 years of PD treatment (p = 0.52). Less than 25% of patients from each group became anuric and there was no difference in time to development of complete anuria between the treated and untreated groups. In the second approach, 130 patients were included: 37 were treated with ACEi/ARBs and 93 were not. Again, no difference was found between the 2 groups with respect to the rate of decline of rGFR and time of anuria development., Conclusion: Our findings are not in line with the results of previous RCTs. The biggest limitation of observational studies is the inability to avoid confounding by indication. However, a RCT in such a setting also does not give a reliable answer. Given all the benefits of ACEi/ARBs, the medications should not be withheld from PD patients. However, their renoprotective effects may often be overruled by other factors influencing the time course of rGFR.

- Abstract
Background: Peritoneal dialysis (PD) technique failure is high compared to hemodialysis (HD). There is a lack of data on the impact of duration of PD treatment on technique survival and on whether there is a difference in risk factors with respect to early and late failure. The aim of this study was to clarify these issues by performing a time-dependent analysis of PD technique and patient survival in a large cohort of incident PD patients., Methods: We analyzed 709 incident PD patients participating in the Netherlands Cooperative Study on the Adequacy of Dialysis (NECOSAD), who started their treatment between 1997 and 2007. We compared technique and patient survival on PD in 4 periods of follow-up: within the first 3 months, and after 3 - 12 months, 12 - 24 months, and 24 - 36 months of treatment. Cox proportional hazards model was used to analyze survival on PD and technique failure. Risk factors were also identified by comparing patients that were transferred to HD with those that remained on PD. Incidence rates for every cause of dropout for each period of follow-up were calculated to establish their trends with respect to PD treatment duration., Results: There was a significant increase in transplantation rate after the first year of treatment. The rate of switching to HD was highest during the first 3 months and decreased afterward. One-, 2- and 3-year technique survival was 87%, 76%, and 66%, respectively. Age, diabetes, and cardiovascular disease appeared to be risk factors for death on PD or switch to HD: a 1-year increase in age was associated with a relative risk (RR) of PD failure of 1.04 [95% confidence interval (CI) 1.003 - 1.06]; for diabetes, RR of stopping PD after 3 months of treatment increased from 1.8 (95% CI 1.1 - 3) during the first year to 2.2 (95% CI 1.3 - 4) after the second year; cardiovascular disease had a major impact in the earliest period (RR 2.5, 95% CI 1.2 - 5) and had a stable influence further on (RR 2, 95% CI 1.1 - 3.5). Loss of 1 mL/minute residual glomerular filtration rate (rGFR) appeared to be a significant predictor of PD failure after 3 months of treatment, but within the first 2 years, RR was 1.1 (95% CI 1.04 - 1.25)., Conclusions: In The Netherlands, transplantation is a main reason to stop PD treatment. The incidence of PD technique failure is at its highest during the earliest months after treatment initiation and decreases later due to fewer catheter and abdominal complications as well as less influence of psychosocial factors. Risk factors for PD discontinuation are those responsible for patient survival: age, cardiovascular disease, diabetes, and rGFR.

- Abstract
A review is given of the various available strategies that can be used to protect the peritoneal membrane. A discussion of experimental studies on approaches that are still experimental, but that might be applied in patients in the future, follows. The currently available approaches include dietary sodium restriction, use of high-dose loop diuretics and of inhibitors of the renin-angiotensin system. All should preferably be combined with a dialysis prescription aimed at reducing the patient's exposure to glucose and its degradation products. The experimental studies indicate favorable effects of combining osmotic agents, together with drugs that interfere with the polyol pathway and the formation of advanced glycosylation end-products.

- Abstract
Background: Experimental studies showed that inhibition of AII effects attenuates the development of peritoneal membrane fibrosis and neoangiogenesis. The latter leads to an increase of peritoneal solute transport and ultrafiltration failure. The results of a single-centre study showed that use of ACEI/ARB can prevent the increase of small solute transport in long-term PD patients. Our aim was to investigate whether these results would also be present in a larger population and influence patient and technique survival in long-term PD., Methods: We analysed data from 217 long-term CAPD patients, participating in the Netherlands Cooperative Study on Adequacy of Dialysis (NECOSAD). Included patients underwent CAPD therapy for at least 2 years; 120 of them were treated with the ACE/AII inhibitors-ACEI/ARB group. The control group consisted of 87 patients who received none of the above drugs and 10 patients who had them for <25% of their time on PD., Results: A significant difference in the time course of peritoneal transport was found between the two groups. The value of 24-h D/P creatinine was associated with the PD duration (P = 0.01) and its time course was influenced by use of ACEI/ARB (P = 0.05). We found no effect of ACEI/ARB on patient survival, but some benefit was found for the technique survival: in a multivariate model the hazard ratio for the group with the longest use of ACEI/ARB was 0.5 (CI 0.22-1.4), P = 0.19., Conclusions: We conclude that AII inhibition prevents the increase in small solute transport in long-term PD. These drugs may also have some positive influence on PD technique survival.

- Abstract
Background: Long-term peritoneal dialysis (PD) may lead to peritoneal fibrosis and ultrafiltration failure. The latter occurs due to high solute transport rates and diabetiform peritoneal sclerosis. Angiotensin-II (AII) is known to be a growth factor in the development of fibrosis and a number of animal studies have shown it likely that inhibiting the effects of AII by angiotensin-converting enzyme (ACE) or angiotensin receptor blocker (ARB) will attenuate these complications., Objective: To investigate the effects of ACE/AII inhibitors in long-term PD patients., Patients and Setting: We analyzed data from 66 patients treated with PD therapy at our center for at least 2 years, during which time at least 2 standard peritoneal permeability analyses (SPAs) were performed. 36 patients were treated with ACE/AII inhibitors (ACE/ARB group); the other 30 received none of the above drugs during the entire follow-up (control group). The two groups were compared with respect to changes in peritoneal transport over the follow-up time., Results: A significant difference in time course of peritoneal transport was found between the 2 groups: in the ACE/ARB group, small solute transport had decreased, while it had increased in the control group. This finding was confirmed by analysis using mixed model for repeated measures. The value of mass transfer area coefficient of creatinine was influenced by the duration of PD therapy (p = 0.017) and this interaction was different with respect to use of ACE/AII inhibitors (p = 0.037). The trend was not found in protein clearances or fluid kinetics., Conclusion: Our findings suggest that ACE/AII inhibition is likely to prevent the increase in mass transfer area coefficients that occurs in long-term PD, which is in line with results of experimental animal studies.

- Abstract
The state of the pancreatic endocrine apparatus in diabetes, adaptation to hypoxia and both of them were studied in experiments with rats. Early stages of diabetes were accompanied by marked reconstruction of the pancreas. A decrease in the insulin level was followed by compensatory activation of glucagon- and somatostatine-producing systems which depended on the sex of animals. It was observed that adaptation to intermittent hypoxia exerted a positive effect on the diabetic process in rats, which was manifested by an increase in the insulin level in blood and beta-cells, inhibition of islet destruction, new formation of beta-cells in acinar tissue, and decrease of glucagon and somatostatine production.
