Динамика выживаемости больных муковисцидозом в Москве и Московской области за периоды 1992–2001 и 2002–2011 гг.

Summary. The aim of this study was to evaluate changes in survival of patients with cystic fibrosis (CF) in Moscow and Moscow region and to determine factors influencing the survival. We analyzed outpatient medical records of patients followed-up in Moscow CF centers by the 1st of January, 2002, and by the 1st of January, 2012.Median survival for 2002–2012 was 37.2 years; this was significantly higher that the similar value for the previous decade (25.9 years). A total number of CF patients was more than doubled due to increased survival and improved diagnosis of the disease.Improved survival was due to improved work of CF centers and to implementation of effective medications, primarily dornase alfa (Pulmozyme) and some inhaled and systemic antibiotics and macrolides in subinhibitory concentrations, in routine clinical practice. Gram-negative infection, especially Burkholderia cepacia, was shown to decrease survival in CF patients in contrary to "mild" mutations that are better prognostic factors.Резюме. Целью работы явилось определение динамики числа и выживаемости больных муковисцидозом (МВ) в Москве и Московской области, а также определение факторов, влияющих на выживаемость. Были проанализированы амбулаторные карты больных, состоящих на учете в московских центрах муковисцидоза на 01.01.2002 и 01.01.2012.Медиана выживаемости больных за периоды 2002–2011 гг. составила 37,2 года, что достоверно выше, чем аналогичный показатель за предыдущее 10-летие – 25,9 года. Отмечено более чем 2-кратное увеличение общего количества больных, обусловленное ростом выживаемости и улучшением диагностики.Увеличение выживаемости обусловлено оптимизацией работы центров МВ и началом рутинного применения различных эффективных медикаментозных препаратов, прежде всего дорназы альфа (Пульмозим), а также некоторых ингаляционных и системных антибиотиков, макролидов в субингибирующих концентрациях. Показано, что инфицирование грамотрицательной инфекцией, особенно Burkholderia cepacia, снижает выживаемость пациентов с МВ, а наличие "мягкого" генотипа является более благоприятным прогностическим фактором

Spatial, temporal, and demographic patterns in prevalence of smoking tobacco use and attributable disease burden in 204 countries and territories, 1990-2019: a systematic analysis from the Global Burden of Disease Study 2019

Background Ending the global tobacco epidemic is a defining challenge in global health. Timely and comprehensive estimates of the prevalence of smoking tobacco use and attributable disease burden are needed to guide tobacco control efforts nationally and globally. Methods We estimated the prevalence of smoking tobacco use and attributable disease burden for 204 countries and territories, by age and sex, from 1990 to 2019 as part of the Global Burden of Diseases, Injuries, and Risk Factors Study. We modelled multiple smoking-related indicators from 3625 nationally representative surveys. We completed systematic reviews and did Bayesian meta-regressions for 36 causally linked health outcomes to estimate non-linear dose-response risk curves for current and former smokers. We used a direct estimation approach to estimate attributable burden, providing more comprehensive estimates of the health effects of smoking than previously available. Findings Globally in 2019, 1·14 billion (95% uncertainty interval 1·13–1·16) individuals were current smokers, who consumed 7·41 trillion (7·11–7·74) cigarette-equivalents of tobacco in 2019. Although prevalence of smoking had decreased significantly since 1990 among both males (27·5% [26·5–28·5] reduction) and females (37·7% [35·4–39·9] reduction) aged 15 years and older, population growth has led to a significant increase in the total number of smokers from 0·99 billion (0·98–1·00) in 1990. Globally in 2019, smoking tobacco use accounted for 7·69 million (7·16–8·20) deaths and 200 million (185–214) disability-adjusted life-years, and was the leading risk factor for death among males (20·2% [19·3–21·1] of male deaths). 6·68 million [86·9%] of 7·69 million deaths attributable to smoking tobacco use were among current smokers. Interpretation In the absence of intervention, the annual toll of 7·69 million deaths and 200 million disability-adjusted life-years attributable to smoking will increase over the coming decades. Substantial progress in reducing the prevalence of smoking tobacco use has been observed in countries from all regions and at all stages of development, but a large implementation gap remains for tobacco control. Countries have a clear and urgent opportunity to pass strong, evidence-based policies to accelerate reductions in the prevalence of smoking and reap massive health benefits for their citizens.
