Diseases of the cardiovascular system remain an important medical and social problem throughout the world, since the prevalence, features of the clinical course and outcomes lead to a significant decrease in the quality of life. The study of the geographic variability of varicose veins of the lower extremities (hereinafter – VLE) can expand the understanding of this problem. Objective. To assess the regional features of the incidence of VLE in Kazakhstan for 2009-2018. Material and methods. The material for the study was the data of the Ministry of Health of the Republic of Kazakhstan – annual form No. 12, concerning VLE (ICD 10 – I83) for 2009-2018. A retrospective study using descriptive and analytical methods of biomedical statistics was used as the main method. Results and discussion. For 2009-2018 in the republic 158 151 cases of VLE were registered for the first time, of which 37 670 (23.8%) in men and 120 481 (76.2%) in women. The average annual incidence rate of VLE (both sexes) in the republic was 91.6±9.6 per 100,000 of the total population (95% CI=72.8-110.30/0000). The lowest incidence rates of VLE in the entire population were established in Aktobe region – 28.1±1.40/0000 (95% CI=25.4-30.80/0000). Very high incidence rates (both sexes) were detected in North Kazakhstan region (130.5±7.60/0000, 95% CI=115.6-145.40/0000) and in Astana city (163.0±11.00/0000, 95% CI=130.6-195.40/0000). Conclusions. The study showed a preliminary assessment of VLE incidence in the republic, identifying regions of low and high frequency, trends of VLE morbidity. In dynamics, morbidity rates tended to grow. With the equalization of the incidence rates of VLE, the average annual growth rate was Т=+12.5%. Keywords: varicose veins of the lower extremities, incidence, Kazakhstan.

This chapter is written in order to give students general summary of basic statistical methods, techniques, indicators and procedures. However emphasis is on the application of those that are frequently used in biomedical research. Statistics is science about data, but data that represent numbers with their context. Therefore, in this chapter the topics of population, samples, types of variables, descriptive statistics and statistical inference will be briefly covered. At the end, correlation and regression analysis will be briefly presented. The aim of this chapter is to give a very short overview of the main principles; techniques and procedures that should be used in order to obtain and understand analyzed biomedical data.

About 800 thousand new cases of cervical cancer (CC) are predicted, and it is expected that about 460 thousand women will die from this pathology, according to the forecasts of the International Agency for Research on Cancer in 2040. To this aim, an analysis studying the indicators of the cancer service for CC also allows us to evaluate the effectiveness of anti-cancer measures in the Republic of Kazakhstan. Aim: Evaluate some indicators of the cancer service at CC in Kazakhstan for 2009-2018. Materials and methods. The research material was data from the Ministry of Health of the Republic of Kazakhstan – annual form No.7 and 35 regarding CC (ICD10–C53) for 2009-2018 – incidence, mortality, early diagnosis, neglect, morphological verification. A retrospective study using descriptive and analytical methods of biomedical statistics was used as the main method. Results and discussion. For 2009-2018, 16,441 new cases of CC were registered in the Republic for the first time, and 6,461 women died from this disease. The crude CC incidence rate increased from 16.3±0.4‰ (2009) to 19.5±0.5‰ in 2018 (p=0.000). In dynamics, mortality rates from CC tended to decrease from 8.4±0.3‰ (2009) to 6.4±0.3‰ in 2018 (р=0.000). The research of the study period reveals a trend: early diagnosis indicators (specific weight of patients with I-II stage) improved from 79.8% (2009) to 88.1% in 2018, and accordingly the specific weight of neglected patients significantly decreased with stage III (from 15.4% to 8.9%) and with stage IV (from 3.4% to 2.7%). The morphological verification indicators for CC remained virtually unchanged, remaining fairly high 99.2% and 99.3%, respectively, in 2009 and 2018. Conclusion. An analysis of the indicators of the cancer service in CC revealed an improvement in morphological verification and early diagnosis, a decrease in neglect and mortality rates, which is undoubtedly associated with regular anti-cancer activities in Kazakhstan, in particular CC screening.

Abstract Phenomenology of illness and abnormalityHabitually, illness or disease is considered as something abnormal. Therefore, the distinction between health/illness is often conflated with the distinction normal/abnormal. Inspired by Kurt Goldstein’s work, Merleau-Ponty makes clear, however, that abnormality does not automatically coincide with pathology. It is also interesting to note that Merleau-Ponty nowhere uses the term “abnormal” to indicate the opposite of the normal person. Similar to Georges Canguilhem he uses the pair “the normal (person)” (le normal) ‐ “the sick person”, “the pathological” (le malade, le pathologique). As Goldstein and Canguilhem make more explicit than Merleau-Ponty, the abnormal person or “deviant” is very often not sick. Instead of approaching physical symptoms from an external or statistical view (which might lead to the conclusion that something is abnormal), they claim that sickness should be defined by the patient’s own lived experience. Merleau-Ponty shares this view, but for different reasons. Goldstein and Canghuilhem, both trained clinicians, believe that patients’ own experiences should be central in clinical practice instead of objectifying measurements and tests. For Merleau-Ponty, the phenomenologist, objective physical features have no place within his phenomenology of lived bodily experience. Bracketing positivist scientific insights, phenomenology also excludes biomedical statistics from its analysis. If we assume that abnormality is a result from a comparison with what is statistically seen as normal, this means that a phenomenology of abnormal embodiment might seem a contradiction in terms. In this paper, however, I would like to show that abnormal embodiment can also be approached from a phenomenological perspective. While drawing on some ideas by Hacking on the history of statistical reasoning, I demonstrate how the statistics of abnormality directly interconnects with lived experience. Hacking explains how the descriptive “average” or “mean” has become the normative “normal”. Because our world is in many ways determined by averages, it is an illusion to think that phenomenology can just bracket statistics. The one who appears physically as abnormal can, comparable to the one who is ill, experience that his or her embodied possibilities to deal with the world dwindle. What I show in this article is that even though a clear distinction can be made between illness and abnormality, both can be accompanied by a reduction or disruption of the “I can”.
