Obesogenic dietary intake in families with 1-year-old infants at high and low obesity risk based on parental weight status: baseline data from a longitudinal intervention (Early STOPP)

PURPOSE: To compare dietary intake in 1-year-old infants and their parents between families with high and low obesity risk, and to explore associations between infant dietary intake and relative weight. METHODS: Baseline analyses of 1-year-old infants (n = 193) and their parents participating in a longitudinal obesity intervention (Early STOPP) were carried out. Dietary intake and diet quality indicators were compared between high- and low-risk families, where obesity risk was based on parental weight status. The odds for high diet quality in relation to parental diet quality were determined. Associations between measured infant relative weight and dietary intake were examined adjusting for obesity risk, socio-demographics, and infant feeding. RESULTS: Infant dietary intake did not differ between high- and low-risk families. The parents in high-risk families consumed soft drinks, French fries, and low-fat spread more frequently, and fish and fruits less frequently (p < 0.05) compared to parents in low-risk families. Paternal intake of vegetables and fish increased the odds for children being consumers of vegetables (OR 1.7; 95 % CI 1.0-2.9) and fish, respectively (OR 2.5; 95 % CI 1.4-4.4). Infant relative weight was weakly associated with a high intake of milk cereal drink (r = 0.15; p < 0.05), but not with any other aspect of dietary intake, obesity risk, or early feeding patterns. CONCLUSIONS: At the age of one, dietary intake in infants is not associated with family obesity risk, nor with parental obesogenic food intake. Milk cereal drink consumption but no other infant dietary marker reflects relative weight at this young age.published_or_final_versio

Magnetoresistance in semiconductor structures with hopping conductivity: effects of random potential and generalization for the case of acceptor states

We reconsider the theory of magnetoresistance in hopping semiconductors. First, we have shown that the random potential of the background impurities affects significantly preexponential factor of the tunneling amplitude which becomes to be a short-range one in contrast to the long-range one for purely Coulomb hopping centers. This factor to some extent suppresses the negative interference magnetoresistance and can lead to its decrease with temperature decrease which is in agreement with earlier experimental observations. We have also extended the theoretical models of positive spin magnetoresistance, in particular, related to a presence of doubly occupied states (corresponding to the upper Hubbard band) to the case of acceptor states in 2D structures. We have shown that this mechanism can dominate over classical wave-shrinkage magnetoresistance at low temperatures. Our results are in semi-quantitative agreement with experimental data.Comment: 19 pages, 3 figure

Experience of long-term use of anti-IgE therapy in a patient with chronic spontaneous urticarial

Chronic spontaneous urticaria is an urgent health problem. Recurrent urticarial rashes, angioedema and severe itching reduce the quality of life of patients. The ineffectiveness of standard therapy requires the search for new modern methods of treating this disease. Taking into account the current data on the pathogenesis, the third line of therapy for chronic spontaneous urticaria is the addition of anti-IgE therapy (omalizumab) to antihistamines of the 2nd generation. The presented clinical case is devoted to the experience of long-term use of omalizumab in a patient with chronic spontaneous urticaria. Having a disease duration of about a year, the patient was thoroughly examined, all concomitant diseases were identified and compensated, parasitic invasion was treated, but this did not lead to a regression of symptoms. Antihistamines of the 2nd generation in standard and increased doses (up to 4 times) did not control the disease, systemic glucocorticosteroids stopped the symptoms for a short time, and therefore, in  the future, the  patient began to use them independently and uncontrollably. Almost daily use of  corticosteroids for 6 months caused the development of complications in the form of weight gain and Cushing’s syndrome. Omalizumab completely stopped all the symptoms during the first day, no side effects were detected. The clinical effect lasted from 3 to 4 weeks. Thus, omalizumab therapy allowed the patient to almost completely get rid of the symptoms of CSC, which significantly improved the quality of life and made it possible to cancel systemic glucocorticosteroids. The peculiarity of the presented case is the duration of the use of omalizumab (more than 2 years) with the inability to cancel due to the return of urticarial rashes and itching

ПОРІВНЯЛЬНА ХАРАКТЕРИСТИКА ДЕЯКИХ МЕТОДІВ ВИДІЛЕННЯ ЗБУДНИКІВ ҐРУНТОВИХ ІНФЕКЦІЙ

In the spread of infectious diseases important value belongs to environment that surrounds animals, meaning second link of epizootic chain (transmission factors). It is known that from sick animals, a large amount of microorganisms, which depends on the ways of spreading into environment, link to contamination of facilities, premises for animal care, soil, water and so on.The paper shows comparative data on the performance of specific laboratory methods used to allocate from the soil pathogens three types of spore infections (Cl. Chauvoei, Cl. Perfringens and Bas. Anthracis).For comparative evaluation methods of soil preparation for bacteriological research for the purpose of allocation of the above pathogens, using sterile and non-sterile soil samples, – growth medium – meat – peptone broth and agar, Kitt – Tarotstsi, blood glucose meat – agar and peptone various concentrations of test – strains of spores in the soil (100 thousand / d, 10 thousand / g, 1 thousand / g and 0.1 thousand / g).In the first experiment to 1 g sample of soil was added 10 cm3 of 0,85 % solution of sodium chloride (dilution 1:10), in the second experiment to soil sample 50 g was added to 50 cm3 distilled water (dilution 1: 1), the third experiment, proposed by us, to 10 g of soil was added 50 cm3 distilled water (dilution 1: 5).Comparing received positive results of research to highlight soil pathogens as infections from non-sterile and sterile soil samples from all growth medium at a specified concentration of spores in 1 g, they were in the first experiment – 23,3 %, the second 30 % and 46,7 % in the third.В распространении инфекционных болезней важное значение принадлежит объектам окружающей среды, которые окружают животных, то есть во втором звене эпизоотической цепи (фактороми передачи). Известно, что от больных животных выделяется большое количество микроорганизмов, которые в зависимости от путей выделения во внешнюю среду, контаминируют помещения, средства ухода за животными, почву, воду и тому подобное.В работе приведены сравнительные данные об эффективности отдельных лабораторных методов, используемых с целью выделения из почвы возбудителей трех споровых инфекций (Cl. chauvoei, Cl. perfringens та Bас. anthracіs).Для сравнительной оценки методов подготовки почвы для бактериологического исследования с целью выделения указанных выше возбудителей инфекций, использовали стерильные и нестерильные образцы почвы, питательные среды – мясо – пептонный бульон и агар, Китт – Тароцци, кровяное глюкозный мясо – пептонный агар и различных концентраций тест - штаммы спор в почве (100 тыс/г, 10 ты /г, 1 тыс /г и 0,1 тыс/г).В первом опыте до 1 г исследуемого образца почвы добавляли 10 см3 0,85 % раствора натрия хлорида (разведение 1:10), во втором опыте до навески почвы 50 г добавляли 50 см3 дистиллированной воды (разведение 1:1), в третьем опыте, предложенного нами, до 10 г почвы доливали 50 см3 дистиллированной воды (разведение 1:5).Сравнивая, полученные ниже, положительные результаты исследований с целью выделения возбудителей грунтовых инфекций, как с нестерильного, так и со стерильного образцов грунта на всех питательных средах при указанной концентрации спор в 1 г, они составляли в первом опыте – 23,3 %, во втором 30 % и в третьем 46,7 %.У поширенні інфекційних хвороб важливе значення належить об’єктам довкілля, які оточують тварин, тобто другій ланці епізоотичного ланцюга (факторам передачі). Відомо, що від хворих тварин виділяється велика кількість мікроорганізмів, які в залежності від шляхів виділення у зовнішнє середовище, контамінують приміщення, засоби догляду за тваринами, ґрунт, воду тощо.В роботі наведені порівняльні дані про ефективність окремих лабораторних методів, що використовуються з метою виділення з грунту збудників трьох спорових інфекцій (Cl. chauvoei, Cl. perfringens та Bас. anthracіs).Для порівняльної оцінки методів підготовки грунту для бактеріологічного дослідження з метою виділення наведених вище збудників інфекцій, використовували стерильні і нестерильні зразки грунту, поживні середовища – м'ясо – пептонний бульйон і агар, Кітт – Тароцці, кров’яний глюкозний м'ясо – пептонний агар та різних концентрацій тест – штами спор у грунті (100 тис/г, 10 тис/г, 1 тис/г та 0,1 тис/г).У першому досліді до 1 г досліджуваного зразка грунту додавали 10 см3 0,85 % -го розчину натрію хлориду (розведення 1:10), у другому досліді до наважки грунту 50 г додавали 50 см3 дистильованої води (розведення 1:1), у третьому досліді, запропонованого нами, до 10 г грунту доливали 50 см3 дистильованої води (розведення 1:5).Порівнюючи, отримані нижче, позитивні результати досліджень з метою виділення збудників грунтових інфекцій як з нестерильного, так і з стерильного зразків грунту на всіх живильних середовищах за вказаної концентрації спор в 1 г, вони становили у першому досліді – 23,3 %, у другому 30 % і у третьому 46,7 %

Experience with the triple fixed combination in patients with chronic obstructive pulmonary disease

Chronic obstructive pulmonary disease (COPD) is one of the most important problems of modern medicine associated with a high mortality rate, high costs of treatment and relief of exacerbations of COPD. The main objectives of COPD treatment are symptom control, reduce the frequency of exacerbations and hospitalizations, and reduced risk of exacerbation in the future. The recommendations of the GOLD initiative propose a treatment approach based on the assessment of exacerbation rates external respiratory function indicators (spirometric classification of GOLD), the severity of symptoms assessed on the CAT test and mMRC. When choosing therapy, the physician must first of all take into account the effectiveness, safety of the drug, adherence to treatment in order to achieve the therapeutic goals of treating patients with COPD. The change in therapeutic approaches in COPD treatment is associated with the accumulation of knowledge in physiology, clinical pharmacology, and the isolation of new clinical phenotypes of COPD. Currently, the main classes of drugs for the treatment of COPD are long-acting beta-agonists (LABA), longacting anticholinergics (LAMA), and inhaled glucocorticosteroids (ICS). The evolution of therapeutic approaches in COPD treatment has led to the creation of new fixed inhalation combinations of the main groups of drugs for COPD treatment. The therapeutic strategies recommended by GOLD and the Russian Federal Guidelines determine the long-term goals of COPD treatment – the impact on the risk of exacerbations in the future. The presented clinical observation of a patient with severe COPD demonstrates the effectiveness of a triple fixed combination vilanterol/umeclidinium/fluticasone furoate 55/22/92 μg as a basic therapy. The  chosen treatment strategy not only reduces the  severity of  the  symptoms of  the  disease, but also reduces the  risk of exacerbations in the future

Free-radical oxidation as a pathogenetic factor of metabolic syndrome

The medical and social significance of cardiovascular diseases remains high. One of the factors that determine cardiovascular risks is metabolic syndrome. As a result of excessive accumulation of lipid and carbohydrate metabolism products in metabolic syndrome, oxidative (oxidative) stress develops. The article considers both domestic and foreign scientific studies, which highlight various aspects of the influence of reactive oxygen and nitrogen species, as well as other free radicals on the formation of oxidative stress in pathological conditions that are part of the metabolic syndrome complex. This describes the mechanisms of the formation of chronic inflammation through excessive secretion of pro-inflammatory cytokines and adipokines, activation of the transcription factor NF-kB, as well as damage to the antioxidant system in obesity. Separately, a number of mechanisms of the stimulating effect of adipokines: leptin, adiponectin, chimerine, omentin 1, resistin, on the formation of oxidative stress have been noted. The ways of activating the polyol pathway, as well as diacyl-glycerol — protein kinase C — the signaling pathway of oxidative stress, the formation of mitochondrial dysfunction is described. As a result of which there is an excessive production of free radicals in insulin resistance, diabetes mellitus and macroand microvascular complications of diabetes. In addition, the influence of oxidative stress directly on the formation of cardiovascular diseases of atherosclerotic genesis, as well as arterial hypertension, has been shown

Features of cellular structure of the induced sputum and profile of cytokines at sintropiya of bronchial asthma and obesity at young patients

Aim. To estimate changes of cellular structure of the induced sputum at young patients with bronchial asthma at interrelations with BMI and level of cytokines in blood plasma. Materials and methods. 164 patients with bronchial asthma were divided into 2 groups taking into BMI: the 1st group included patients with bronchial asthma and BMI from 18 to 25 kg/m2, patients with bronchial asthma and BMI from 30 to 40 kg/m2 entered into the 2nd group. The group of control was made by 40 almost healthy volunteers. Estimated existence of excess weight and defined obesity degree according to recommendations of World Health Organization. Studied the level of control of bronchial asthma, cellular structure of the induced sputum, the IL-2, IL-4, IL-6, IL-8, IL-10, IL-12, IL-15, IL-17, TNF-α, INF-γ levels in plasma of peripheral blood. Results. There are presented the results of the research of cellular profile of the induced sputum and profile of cytokines at patients with bronchial asthma depending on BMI and severity of the disease. The received results testify to prevalence of eosinophilic type of an inflammation in the group of patients with BMI less than 25 kg/m2 whereas at patients mainly paucigranulation inflammation decided on obesity. The highest content of the Il-17 was registered at patients with bronchial asthma and obesity as in comparison with indicators of patients with normal BMI, and with almost healthy that, perhaps, is the reason of low effect of steroid therapy at these patients. Conclusion. Endotype assessment before basic antiinflammatory therapy at patients with the first time diagnosed bronchial asthma, will be able to help with selection of the most optimum treatment to each specific patient

Роль катепсина S в патофизиологии бронхиальной астмы

To date, the study of the role of proteases in the pathogenesis of various diseases remains relevant. The variety of cathepsin functions is associated with the peculiarities of their localization, expression, and regulation, due to which cathepsins are involved in development of many pathologies. Dysregulation of proteases, their inhibitors, and substrates can lead to the development of multiple organ dysfunction.The review presents data on the characteristics of the entire family of cathepsins and cathepsin S, in particular. The pathophysiological role of cathepsin S in the formation of bronchopulmonary pathologies, as well as in bronchial asthma is described, and intraand extracellular implementation mechanisms are considered. The authors believe it is this enzyme that could be targeted in targeted asthma therapy to prevent airway wall remodeling at the earliest stages of the disease. The literature search was carried out in the search engines Medline, eLibrary, Scopus, the Cochrane Library, and RSCI.До настоящего времени сохраняет свою актуальность изучение роли ферментов – протеаз в патогенезе различных заболеваний. Многообразие функций катепсинов обусловлено особенностями их локализации, экспрессии и регуляции, благодаря чему они принимают участие в развитии многих патологических процессов. Дисрегуляция активности протеаз, их ингибиторов и субстратов может привести к развитию полиорганных заболеваний.В обзорной статье представлены данные о характеристике всего семейства катепсинов и катепсина S в частности; описаны его патофизиологические роли при формировании бронхолегочных патологий, а также при бронхиальной астме; освещены внутрии внеклеточные механизмы реализации. Авторы считают, именно этот фермент может стать мишенью для таргетной терапии астмы с целью предотвращения ремоделирования бронхиальной стенки на самых ранних этапах заболевания. Поиск литературы осуществлялся в поисковых системах Medline, еLibrary, Scopus, The Cochrane Library, РИНЦ

The use of “probukol” preparation in complex treatment of the patients with the simple diabetic retinopathy

В последнее десятилетие отмечается рост сосудистых осложнений сахарного диабета, особенно в промышленно развитых странах. Одним из наиболее частых сосудистых осложнений диабета является ретинопатия, которая выявляется у 30-90 % больных. В последние годы появились работы, в которых авторы указывают на важную роль процессов перекисного окисления липидов в патогенезе диабетических ангиопатий, что явилось основанием включения в комплексную терапию сосудистых осложнений препаратов антиоксидантов. Учитывая выше изложенное, нами обследовано 43 больных с простой диабетической ретинопатией, которые на фоне традиционной терапии получали препарат антиоксидантного действия пробукол в суточной дозе 1 г в течение 1-го месяца. В результате проведенного лечения у обследованных больных повысились зрительные функции (острота зрения на 0,1-0,2; у 70% больных расширились границы суммарного поля зрения на 25-30° у 35 %). Анализ биохимических данных выявил достоверность снижения показателей липидного обмена, повышение антиоксидантной обеспеченности и снижение интенсивности ПОЛ. Наиболее выраженный защитный эффект препарат оказал в летне-осенний период, что обусловлено способностью препарата эффективно тормозить перекисные механизмы диабетических ретинопатий в период достаточного поступления алиментарных АО. Представленные результаты оценки защитных свойств пробукола свидетельствуют о перспективности его включения в комплексную терапию, диабетическую ретинопатию; The synthenic antioxidant of inderect action “Probukol” was used in complex treatment of the patients with the simple diabetic retinopathy. We examined 43 patients with the simple from of diabetic retinopathy, who were undergone antioxidant therapy. The received data allow to recommend “Probukol” preparation into complex treatment of the diabetic retinopathy patients
