Sociodemographic characteristics, sexual behaviour and knowledge about cervical cancer prevention as risk factors for high-risk human papillomavirus infection in Arkhangelsk, North-West Russia.

While sociodemographic predictors of cervical cancer (CC) are well understood, predictors of high-risk (HR) human papillomavirus (HPV) infection have not been fully elucidated. This study explored the HR-HPV infection positivity in relation to sociodemographic, sexual behavior characteristics and knowledge about HPV and CC prevention among women who visited the Arkhangelsk clinical maternity hospital named after Samoylova, Russia. This cross-sectional study was conducted in the city of Arkhangelsk, Northwest Russia.

Adverse Pregnancy Outcomes among Adolescents in Northwest Russia: A Population Registry-Based Study.

This study aimed to assess whether adolescents have an increased risk of adverse pregnancy outcomes (APO) compared to adult women. We used data on 43,327 births from the population-based Arkhangelsk County Birth Registry, Northwest Russia, for 2012-2014. The perinatal outcomes included stillbirth, preterm birth (<37 and <32 weeks), low and very low birthweight, 5 min Apgar score <7 and <4, perinatal infections, and the need for neonatal transfer to a higher-level hospital.

Knowledge about human papillomavirus and prevention of cervical cancer among women of Arkhangelsk, Northwest Russia.

Background: Knowledge about cervical cancer (CC) risk factors and benefits of CC prevention motivates women to participate in its screening. However, several studies show that there is a significant knowledge deficit worldwide about human papillomavirus (HPV). The current study explores the level of knowledge about HPV and CC prevention in the context of sociodemographic and behavioral characteristics of women who visited an antenatal clinic in Arkhangelsk, Russia.

Do Cervical Cancer Patients Diagnosed with Opportunistic Screening Live Longer? An Arkhangelsk Cancer Registry Study.

The aim of the current study was to compare cervical cancer (СС) patients diagnosed with and without screening in terms of: (i) sociodemographic and clinical characteristics; (ii) factors associated with survival; and (iii), and levels of risk. A registry-based study was conducted using data from the Arkhangelsk Cancer Registry. It included women with newly diagnosed malignant neoplasm of the uterine cervix during the period of 1 January 2005 to 11 November 2016 (N = 1548).

Key indicators of obstetric and neonatal care in the Republic of Sakha (Yakutia).

In the absence of a medical birth registry, the official statistics are the only sources of information about pregnancy outcomes in the Republic of Sakha (Yakutia) (RS).

[Criteria for evaluating the effectiveness of myocardial infarct patient rehabilitation (posthospital phase)].

On the basis of the analysis of a 24- to 30-month posthospital phase of rehabilitation in 486 patients with myocardial infarction, critera were elaborated for dividing them into 4 classes with mathematically determined severity index. Criteria for analysing rehabilitation efficacy available for wide practice and a definite algorithm for differentiated management of patients with stage by stage appraisal of the condition and reaching alternate decisions are suggested. The strict dependence of the results of the post-hospital rehabilitation phase on the appraisal of the patients, condition and the corresponding correction of the rehabilitation program is shown.

A total of 146 patients with chronic ischaemic heart disease and 90 normal persons were subjected to step-wise bicycle ergometry tests with an analysis of ECG, pulse rate, spiroergometry, cardiac volumes, and ultrasonic location of the posterior wall of the left ventricle. It was demonstrated that the pulse-pressure index that results in ischaemic manifestations can be determined in every patient, i.e.
