Summary Background Sustainable Development Goal 3.2 has targeted elimination of preventable child mortality, reduction of neonatal death to less than 12 per 1000 livebirths, and reduction of death of children younger than 5 years to less than 25 per 1000 livebirths, for each country by 2030. To understand current rates, recent trends, and potential trajectories of child mortality for the next decade, we present the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 findings for all-cause mortality and cause-specific mortality in children younger than 5 years of age, with multiple scenarios for child mortality in 2030 that include the consideration of potential effects of COVID-19, and a novel framework for quantifying optimal child survival. Methods We completed all-cause mortality and cause-specific mortality analyses from 204 countries and territories for detailed age groups separately, with aggregated mortality probabilities per 1000 livebirths computed for neonatal mortality rate (NMR) and under-5 mortality rate (U5MR). Scenarios for 2030 represent different potential trajectories, notably including potential effects of the COVID-19 pandemic and the potential impact of improvements preferentially targeting neonatal survival. Optimal child survival metrics were developed by age, sex, and cause of death across all GBD location-years. The first metric is a global optimum and is based on the lowest observed mortality, and the second is a survival potential frontier that is based on stochastic frontier analysis of observed mortality and Healthcare Access and Quality Index. Findings Global U5MR decreased from 71·2 deaths per 1000 livebirths (95% uncertainty interval [UI] 68·3–74·0) in 2000 to 37·1 (33·2–41·7) in 2019 while global NMR correspondingly declined more slowly from 28·0 deaths per 1000 live births (26·8–29·5) in 2000 to 17·9 (16·3–19·8) in 2019. In 2019, 136 (67%) of 204 countries had a U5MR at or below the SDG 3.2 threshold and 133 (65%) had an NMR at or below the SDG 3.2 threshold, and the reference scenario suggests that by 2030, 154 (75%) of all countries could meet the U5MR targets, and 139 (68%) could meet the NMR targets. Deaths of children younger than 5 years totalled 9·65 million (95% UI 9·05–10·30) in 2000 and 5·05 million (4·27–6·02) in 2019, with the neonatal fraction of these deaths increasing from 39% (3·76 million [95% UI 3·53–4·02]) in 2000 to 48% (2·42 million; 2·06–2·86) in 2019. NMR and U5MR were generally higher in males than in females, although there was no statistically significant difference at the global level. Neonatal disorders remained the leading cause of death in children younger than 5 years in 2019, followed by lower respiratory infections, diarrhoeal diseases, congenital birth defects, and malaria. The global optimum analysis suggests NMR could be reduced to as low as 0·80 (95% UI 0·71–0·86) deaths per 1000 livebirths and U5MR to 1·44 (95% UI 1·27–1·58) deaths per 1...
Aim to analyze the dynamics of the opinions of medical and biological students on the problem of preventing sexually transmitted infections before and during the pandemic of the new coronavirus infection. Material and methods. A sociological survey was conducted in 2017 (372 respondents) and 2021 (574 respondents) among the students of institutions of higher and secondary vocational education in medical and biological specialties. We used the authors' questionnaire, consisting of 54 questions grouped into 5 blocks. In both samples, the principle of equal representation of age, gender, social and professional groups was observed. The average age of the respondents was 19.10.74 years. The distribution of the respondents by sex was as follows: in 2017, female 51.9% (n=193), male 48.1% (n=179); in 2021, female 50.7% (n=291) and male 49.3% (n=283). Both samples had sufficient size to obtain results with the accuracy level of =0.05. The analytical, statistical, sociological methods were used for research. In the processing and presentation of the data, the extensive indicators were used, compared with the assessment of the significance of differences according to Student's t-test. Results. The proportion of people who had an objective idea of the risk of contracting sexually transmitted infections increased from 72.8% (2017) to 87.8% (2021), while the association of the threat only with the frequent change of partners was noted significantly less often (5.9% in 2021 and 16.7% in 2017). The proportion of students linking the risk with social status has decreased from 8.1% to 4.7%, which may indicate a tendency for more objective ideas about the risks of sexually transmitted infections. Conclusion. During the period of the COVID-19 pandemic, the prevalence of an objective self-assessment of the epidemiological situation and the associated risks of contracting sexually transmitted infections increased statistically among students. Also, increased their readiness to undergo screening examinations and seek qualified medical care.
Based on official statistics of the Russian Federal State Statistics Service and the Ministry of Healthcare, the article analyzes the state and dynamics of urological morbidity, along with urologic cancer incidence and mortality in adult population of the Central Federal District vs. entire Russian Federation (RF). It was established that genitourinary diseases are consistently at the top in the structure of RF population morbidity and mortality, often being among leading causes of disabilities as well. The analysis results, using the case-studies of specific nosological forms, constitute an important methodological and informative base for strategic planning of developing both medical and preventive care in the patients, as well as create essential basis for further improvement of specialized outpatient and inpatient types of a health care.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
