Lifestyle factors, including smoking, alcohol (AU) and drug use (DU), can affect male fertility. The aim of the study was to investigate the frequency and characteristics of smoking, AU and DU in men from infertile couples, to identify the most significant associations of disorders of spermatogenesis and social risk factors.Material and methods. At the 1st stage of the study, the case histories of 1198 men from infertile couples were analyzed to determine the frequency of smoking, AU and DU, at the 2nd stage, a more detailed questionnaire of 239 patients from the general sample was conducted for detailed characteristics of smoking and/or AU and/or DU, at the 3rd stage, a comprehensive analysis of ejaculate from men who consumed strong alcohol, but did not smoke or use DU (n = 46) was performed in comparison with men without bad habits taken into account (n = 60).Results. In the general sample, the frequency of AU was 73 %, smoking – 41 %, DU –17 % (mostly in anamnesis). 47.9 % of AU men consumed beer (1.5 (1–2.5) liters per week, 25.6 % – strong alcohol (250 (100–500) ml per week), 7.6 % – champagne/wine (500 (250–725) ml per week); 92.7 % of smokers used cigarettes, 7.3 % – electronic cigarettes (smoking experience was 15 (10–20) years, the number of cigarettes per day was 15 (10–20) pieces); more than 90 % of DU men have a history of non-injection DU. Men who consumed only strong alcohol, but did not smoke and did not use drugs, increased sperm DNA fragmentation compared to men without bad habits taken into account: 16.0 (13.5–19.6) and 12.8 (8.8–19.4) %, respectively, p = 0.018.Conclusions. Among men from infertile couples, a high frequency of AU was revealed with the predominant use of beer or strong alcohol, the use of the latter increases sperm DNA fragmentation; smoking is characterized by a long experience; active DU is rare. Given the specifics of the requirements for the state of reproductive health of men applying to reproductive medicine centers, it is important to have knowledge about the frequency and severity of smoking, AU and DU among them, as well as about the relationship of risk factors of infertility with the parameters of ejaculate.","PeriodicalId":33781,"journal":{"name":"Sibirskii nauchnyi meditsinskii zhurnal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48952886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This analytical review concludes that widespread expression of SP-A and SP-D is documented in numerous studies, and, although the lungs remain the main site of synthesis of surfactant proteins, one can expect its significant impact on the immune and inflammatory response in many organs and tissues. The authors note that there are several known extrapulmonary effects of these proteins.

The rupture of OP mainly occurs in the first trimester of pregnancy 91.0 %, in the second trimester it is 5.3 %, and in the third it’s 3.7 %. Untimely diagnosis of EP in the ovaries can be fatal with massive bleeding and is associated with the risk of ovariectomy with a subsequent decrease in fertility in patients of reproductive age. It is very difficult to diagnose OP. Differential diagnosis should be carried out with interrupted tubal pregnancy, rupture of the ovarian cyst, as well as with torsion of the ovarian cyst. The article presents the results of a pathomorphological study confirming the diagnosis and adequacy of the performed therapeutic measures. The algorithm of OP diagnosis, justification and decision- making on the method of patient’s management and treatment are shown.

Aim of the study was to investigate the parameters of stress at work and in the family among men aged 25–54, employed in expeditionary-shift work in the arctic territories of the Tyumen region.Material and methods. A cross-sectional epidemiological study was conducted on an organized population of men aged 25–54 years, employed in expeditionary-shift work for more than five years at one of the industrial enterprises of the Tyumen region (n = 203). The comparison group consisted of an organized population of men in the same age range working permanently in the city of Tyumen (n = 239). Determination of stress at work and stress in the family was carried out according to the standard WHO questionnaire MONICA-psychosocial.Results and discussion. Among men employed in the expeditionary-shift form of work, most often over the previous 12 months, a change in specialty was established, an increase in the load and responsibility at the workplace, a more negative attitude towards work, an increase in conflicts with subordinates, but also the possibility of rest after a working day with a decrease in ‘other” changes at work; according to the parameters of stress in the family, among them a change in marital status, an increase in conflicts in the family and at the same time opportunities for a relaxing home rest were most often determined.Conclusions. Thus, the results of the pilot study, which determined a significantly higher prevalence of some factors of chronic social stress after five years of work in the arctic territories of the Tyumen region, should become a scientific basis for the formation of a socially oriented preventive program to reduce the risks of developing cardiovascular diseases among workers in the oil and gas production complex employed by the expedition-shift form of work.","PeriodicalId":33781,"journal":{"name":"Sibirskii nauchnyi meditsinskii zhurnal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46519424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the study was to delineate the main steps in formation of a clinical dataset of patients with brain aneurysms from the stage of producing primary mining specifications to formation of a final version.Material and methods. Data collection, crosschecking of the cases and analyses of dataset has been carried out in Turku University Hospital. Within last two decades available medical data at our hospital have been stored in digital data lake thus allowing automatized data mining. In frame of our study, data mining was performed by a data scientist utilizing R software. Inclusion criteria were based on a set of diagnosis which were coded in medical charts according to international classification of diseases (ICD 10).Resutls and Discussion. Primary data mining identified 3850 patients with brain aneurysms treated at our hospital from January 2000 till May 2018. After independent manual crosschecking of medical charts of these patients, we found 1218 (32 %) cases, which had no aneurysm (false-positive). Data of remaining true aneurysm-cases were divided into clinical and intensive care unit subsets where every event linked to particular date of treatment was defined as an info-unit. All the data in both subsets were structured into separate Excel files and presented in chronological order for each particular patient. Altogether, dataset included 70 000 000 rows of info-units found in 2632 patients.Conclusions. Data mining allowed establishment of detailed clinical dataset of patients with brain aneurysms. Produced mining algorithm had limitation regarding false-positive cases (32 % patients). Based on that, we recommend manual crosschecking of automatically collected dataset before statistical analysis.","PeriodicalId":33781,"journal":{"name":"Sibirskii nauchnyi meditsinskii zhurnal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42859024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mevalonate pathway metabolites play an important role in the formation of trained immunity. The aim of this investigation was to study the effect of modulators of mevalonate pathway, mevalonate and zoledronate, on the formation of trained immunity in human and animal monocytes/ macrophages.Material and methods. Human monocyte-like cell lines THP-1 and U-937, peritoneal macrophages of BALB/c mice were used. Trained immunity was induced in vitro by incubation of THP-1 and U-937 monocyte-like cell lines for 24 and 72 hours with inactivated Mycobacteria of BCG vaccine strain, and in vivo by intraperitoneal administration of BCG to BALB/c mice with isolation of peritoneal macrophages on day 7 after infection (lag phase). Cell hyperreactivity was assessed by response to a second stimulus with bacterial lipopolysaccharide (LPS) and mevalonate, zoledranate in the presence or absence of LPS. Lactate, cytokine (IL-1β, TNF-α, IL-10), nitric oxide and glucose level was measured in conditioned media from cells.Results and discussion. The study showed that monocyte-like cell lines THP-1 and U-937 responded differently by cytokine production, lactate, and glucose consumption to BCG stimulus in the presence or absence of lag phase. Mevalonate and zoledronate alone or in combination with LPS also stimulated cytokine production in different ways. The presence of lag phase for human monocyte-like cells is essential for the level of cytokine production and glucose consumption. Peritoneal macrophages have been shown to enhance pro-inflammatory cytokine production in response to LPS, mevalonate, and zoledronate.Conclusions. Mevalonate and zoledronate induce trained immunity in monocytes/macrophages.","PeriodicalId":33781,"journal":{"name":"Sibirskii nauchnyi meditsinskii zhurnal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47067824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main methods for assessing the neuroprotective effect, which is the main component of defense against stress, include the study of behavioral reactions that reflect motor, emotional, and cognitive changes. The study of drugs based on regulatory peptides is promising. Semax (ACTH4-7PGP) is a representative of a new synthetic peptide engineering, practically devoid of a hormonal effect and completely preserving the neurotropic activity of adrenocorticotropic hormone. The aim of the work was an experimental study of the effect of semax on the behavior of animals under the influence of experimental depression based on “social” stress. Material and methods. The study was carried out on 50 outbred male rats aged 6 months. Semax effects were studied under conditions of sensory contact - a model of experimental depression based on the formation of aggressive and submissive behavior in animals, using the multicomponent model the Suok test (“ropewalking”) and the Porsolt test to assess the depressive behavior of rats. Results and its discussion. Intermale confrontations led to a decrease in the time spent in the light half of the test, the number of “exploratory” downward glances, directional head movements; a decrease in the number of visited segments in the light section in victims and aggressors. As a whole, the study of behavioral reactions in animals in the Suok test and the Porsolt test in the model of experimental depression (sensory contact) showed the formation of an anxious-depressive state in animals, which was confirmed by a decrease in the motor and exploratory activity of rats. The results were obtained during the Porsolt test, indicating the formation of a depressive state in animals, which was confirmed by an increase in the total period of immobility in both aggressors and victims, an increase in the time of passive swimming, and a decrease in the time of active swimming. With a comprehensive assessment of animal behavior indicators in the Suok test, against the background of a decrease in the level of anxiety under the influence of semax, an improvement in the parameters of exploratory behavior was observed, in the Porsolt test – of motor activity indicators. Conclusions. Investigation of semax effect on the behavioral reactions of animals under conditions of sensory contact indicates that this drug exhibits an anxiolytic and antidepressant effect, eliminating pathological changes in the psycho-emotional status of animals.","PeriodicalId":33781,"journal":{"name":"Sibirskii nauchnyi meditsinskii zhurnal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45479946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
