Пятилетняя общая выживаемость больных метастатическим раком почки, получавших эверолимус при прогрессировании на фоне лечения бевацизумабом: проспективное многоцентровое исследование CRAD001LRU02T

Background. In a CRAD001LRU02T study of everolimus for metastatic renal cell carcinoma patients previously treated with bevacizumab ±  interferon, median overall survival (OS) was 17.4 months (95 % confidence interval 13.5–21.3 month).Objective of final analysis was to evaluate 5-year OS and long-term toxicity in this study.Materials and methods. Survival data were collected from 37 patients with bevacizumab-refractory metastatic renal cell carcinoma who received everolimus in a completed prospective multicenter study. Patients were predominantly male, 89 % had ECOG performance status of 0/1, 51 % received previous bevacizumab in combination with interferon, and 38/62% had MSKCC favorable/intermediate risk disease.Results. The 5-year survival rate was 16.2% (95 % confidence interval 14.1–18.3 %), with a median follow-up of 5 years. The 1-, and 3-year OS rates were 81.0 and 43.0 %, respectively. The median duration of second-line of everolimus was 315 (range 61–569) days. 11 (29.7 %) patients received third-line therapy with a median duration of 3.6 months. Confirmed objective tumor responses were seen in 5 (14.0 %) patients. 70.0 % (n = 26) patients had a stable disease. 1 (2.7 %) patient achieved complete response after 4 years of therapy. One (2.7 %) patient  discontinued everolimus therapy on their own accord due to relapse of systemic lupus erythematosus and one (2.7 %)  patient had 14-days interruption of an everolimus therapy due to grade 3 hyperglycemia. No grade 4 treatment-related toxicity was found.Conclusions. Everolimus provided an estimated 5-year survival rate of 16.2 % for bevacizumab-resistant metastatic renal cell carcinoma. Prolonged everolimus was not associated with new types or increased severity of adverse events.Введение. В исследовании CRAD001LRU02T эффективности эверолимуса у больных метастатическим почечно-клеточным раком, получавших ранее терапию бевацизумабом в комбинации с интерфероном или без него, медиана общей выживаемости (ОВ) составила 17,4 мес (95 % доверительный интервал 13,5–21,3 мес).Цель работы – оценка 5-летней ОВ и отдаленной токсичности в этом исследовании.Материалы и методы. Данные по ОВ были получены у 37 пациентов, рефрактерных к терапии бевацизумабом и получивших эверолимус в рамках проспективного многоцентрового исследования. Большинство пациентов – мужчины, 89 % больных имели статус по шкале ECOG 0 / 1, 51 % пациентов получили предшествующую терапию бевацизумабом в комбинации с интерфероном. Благоприятный прогноз имели 38 % больных, промежуточный – 62 %.Результаты. При медиане наблюдения 5 лет 5-летняя ОВ составила 16,2 % (95 % доверительный интервал 14,1–18,3 %),  1- и 3-летняя ОВ – 81,0 и 43,0 % соответственно. Медиана продолжительности 2-й линии терапии эверолимусом составила 315 (61–569) сут. С медианой длительности 3,6 мес 3-ю линию терапии получили 11 (29,7 %) пациентов. Подтвержденные объективные ответы отмечены у 5 (14,0 %) больных. Стабилизация болезни наблюдалась у 70,0 % (n = 26) пациентов. Полного ответа спустя 4 года терапии достиг 1 (2,7 %) пациент. Из-за обострения системной красной волчанки 1 (2,7 %) больной по собственному желанию прекратил терапию эверолимусом и 1 (2,7 %) пациент имел перерыв в лечении в течение 14 сут в связи с развитием гипергликемии III степени токсичности. Нежелательных явлений IV степени тяжести не выявлено.Заключение. Терапия эверолимусом привела к 5-летней ОВ 16,2 % у больных метастатическим почечно-клеточным раком, ранее резистентных к терапии бевацизумабом. Длительная терапия эверолимусом не была ассоциирована с новыми видами выраженной токсичности или повышением частоты нежелательных явлений

Biology, Fishery, Conservation and Management of Indian Ocean Tuna Fisheries

The focus of the study is to explore the recent trend of the world tuna fishery with special reference to the Indian Ocean tuna fisheries and its conservation and sustainable management. In the Indian Ocean, tuna catches have increased rapidly from about 179959 t in 1980 to about 832246 t in 1995. They have continued to increase up to 2005; the catch that year was 1201465 t, forming about 26% of the world catch. Since 2006 onwards there has been a decline in the volume of catches and in 2008 the catch was only 913625 t. The Principal species caught in the Indian Ocean are skipjack and yellowfin. Western Indian Ocean contributed 78.2% and eastern Indian Ocean 21.8% of the total tuna production from the Indian Ocean. The Indian Ocean stock is currently overfished and IOTC has made some recommendations for management regulations aimed at sustaining the tuna stock. Fishing operations can cause ecological impacts of different types: by catches, damage of the habitat, mortalities caused by lost or discarded gear, pollution, generation of marine debris, etc. Periodic reassessment of the tuna potential is also required with adequate inputs from exploratory surveys as well as commercial landings and this may prevent any unsustainable trends in the development of the tuna fishing industry in the Indian Ocean

Cellobiose Dehydrogenase Aryl Diazonium Modified Single Walled Carbon Nanotubes: Enhanced Direct Electron Transfer through a Positively Charged Surface

One of the challenges in the field of biosensors and biofuel cells is to establish a highly efficient electron transfer rate between the active site of redox enzymes and electrodes to fully access the catalytic potential of the biocatalyst and achieve high current densities. We report on very efficient direct electron transfer (DET) between cellobiose dehydrogenase (CDH) from Phanerochaete sordida (PsCDH) and surface modified single walled carbon nanotubes (SWCNT). Sonicated SWCNTs were adsorbed on the top of glassy carbon electrodes and modified with aryl diazonium salts generated in situ from p-aminobenzoic acid and p-phenylenediamine, thus featuring at acidic pH (3.5 and 4.5) negative or positive surface charges. After adsorption of PsCDH, both electrode types showed excellent long-term stability and very efficient DET. The modified electrode presenting p-aminophenyl groups produced a DET current density of 500,mu A cm(-2) at 200 mV vs normal hydrogen reference electrode (NHE) in a 5 mM lactose solution buffered at pH 3.5. This is the highest reported DET value so far using a CDH modified electrode and comes close to electrodes using mediated electron transfer. Moreover, the onset of the electrocatalytic current for lactose oxidation started at 70 mV vs NHE, a potential which is 50 mV lower compared to when unmodified SWCNTs were used. This effect potentially reduces the interference by oxidizable matrix components in biosensors and increases the open circuit potential in biofuel cells. The stability of the electrode was greatly increased compared with unmodified but cross-linked SWCNTs electrodes and lost only 15% of the initial current after 50 h of constant potential scanning

Продолжительность жизни больных метастатическим почечно-клеточным раком в Российской Федерации: результаты многоцентрового регистрового исследования RENSUR3

Background. Overall survival (OS) data obtained in patients with metastatic renal cell carcinoma (mRCC) in real-world settings are rarely published. The objective of the RENSUR3 registry study was to collect information on the use of various therapeutic options for mRCC in real-world clinical practice and assess OS in a Russian population.Methods. Patients were retrospectively identified at 8 cancer centres in different Russian regions and enrolled in the study if the diagnosis of mRCC had been made in the period from January 2015 to December 2016. Anonymous data were collected online, the registry contained demographic characteristics and treatment and outcome data.Results. The study had 573 subjects included in the analysis. The average age of patients at mRCC diagnosis was 63.1 years; 14.5 % of them were aged > 75 years. 65.6 % of the subjects were men; 72% had received surgical treatment for the primary tumour; clear cell and non-clear cell carcinomas were detected in 84 % and 16 % of the patients, respectively.Drug therapy was used in 307 patients (54%). The median duration of any line of therapy was 10 months (95% CI 7.6-12.4). The most frequent treatment option was interferon (administered 161 times as part of any line of therapy or at different stages of treatment). Targeted therapy was given to 160 patients (52.1%), 112 of whom received it as first-line therapy. 87 subjects (28.3%) received > 2 lines of therapy. The 3-year OS rate was 21%, and the median OS was 12 months (95% CI 11.1-12.9). The median OS in the therapy and no therapy groups was 15.1 months and 6.9 months, respectively (Р<0.0001). The median life expectancy in patients receiving second-line therapy (median 18.4 months) was significantly higher than in patients treated with first-line therapy only (10.9 months, Р<0.001).Conclusions: The OS results of the RENSUR3 study are unsatisfactory, which apparently can be explained by the fact that drug therapy was used in only half the patients, the infrequent use of targeted drugs, and the rare administration of targeted therapy for second and subsequent lines of therapy in patients with progressive disease. Introduction of the latest drug therapy options, including checkpoint inhibitors, will help improve patients» life expectancy.Введение. Данные по общей выживаемости (ОВ) пациентов с метастатическим почечно-клеточным раком (мПКР) в реальной жизни публикуются редко. Задача регистрового исследования RENSUR3 заключалась в сборе сведений по применению разных вариантов терапии при мПКР в условиях реальной клинической практики и оценке ОВ в популяции российских пациентов.Методы. Пациентов ретроспективно идентифицировали в 8 онкологических центрах в разных регионах России и включали в исследование, если диагноз мПКР был установлен в период с января 2015 г. по декабрь 2016 г. Анонимные сведения собирали онлайн, регистр охватывал демографические характеристики, а также данные по терапии и исходам.Результаты. В исследование для анализа было включено 573 больных, 65,6 % из них составили мужчины. Средний возраст пациентов на момент постановки диагноза мПКР составил 63,1 года, при этом 14,5% были в возрасте >75 лет. 72% прошли хирургическое лечение по поводу первичной опухоли; светлоклеточный и несветлоклеточный рак был выявлен у 84% и 16% пациентов, соответственно.Лекарственная терапия проводилась 307 (54%) пациентам. Медиана продолжительности всех линий терапии составила 10 месяцев (95% ДИ 7,6-12,4). Наиболее часто применявшимся вариантом лечения было назначение интерферона (частота — 161 раз в любой из линий или на различных этапах лечения). Таргетная терапия проводилась у 160 (52,1%) пациентов, из них в качестве первой линии таргетную терапию получили 112 пациентов. 87 (28,3%) больных получили >2 линий терапии. 3-летняя ОВ составила 21 %, а медиана ОВ — 12 месяцев (95 % ДИ 11,1-12,9). Медиана ОВ в группах получивших и не получивших терапию пациентов составила 15,1 и 6,9 месяца, соответственно (Р<0,0001). Продолжительность жизни пациентов, прошедших вторую линию терапии (медиана — 18,4 месяца), была значительно дольше, чем у пациентов, получивших только первую линию терапии (10,9 месяца, Р<0,001).Выводы. Показатели ОВ в исследовании RENSUR3 являются неудовлетворительными, что, по-видимому, можно объяснить назначением лекарственного лечения только половине пациентов, низкой частотой применения таргетных препаратов, редким назначением таргетной терапии во второй и последующих линиях при прогрессировании болезни. Внедрение новейших вариантов лекарственного лечения, в том числе ингибиторов контрольных точек, будет способствовать улучшению продолжительности жизни больных

We assessed the efficacy and safety of treatment with docetaxel plus either ramucirumab-a human IgG1 VEGFR-2 antagonist-or placebo in this patient population

Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study

Summary Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030
