[Assessment of the professional community awareness about innovative diets prescribed for hypertension].

Due to the fact of constantly increasing incidence of arterial hypertension and the large role of nutrition in the treatment and prevention of this disease, the assessment of the awareness of the medical community and patients about the trends in the development of therapeutic and prophylactic diets is relevant. The aim of the research was to assess the physician and patient awareness on the trends in the development of therapeutic and prophylactic diets and different rations prescribed for hypertension prevention. Material and methods. On the SurveyMonkey platform, questionnaires were created for different medical specialties and patient of various departments. Access to the survey was free, the mailing list was carried out through the professional communities of physicians on the Internet. In turn, the doctors-respondents were asked to distribute the link for patients among those who were undergoing treatment or were on dispensary observation for the pathology of the cardiovascular system. Respondents were asked about their attitudes, knowledge, and compliance with existing dietary guidelines. The number of respondents was 300 doctors of various specialties and 300 patients. Results. The most recognizable dietary recommendations among patients were: low-calorie (41.1%), low-carbohydrate (39.4%), vegetarian (39.0%). However, the most popular (the commitment to them was the greatest) were: low in calories (27.6%), low in carbohydrates (25.6%), low in fat (24.4%). Among the doctors, the distribution was as follows - in addition to the classic therapeutic and prophylactic diets prescribed for certain diseases, the most recognizable diets were: Mediterranean (59.8%), low-calorie (59.0%), low-fat (57.3%); and the most commonly prescribed: Mediterranean (47.0%), low-carb (44.4%), low-fat (40.2%). The most recognizable dietary pattern among patients was the low-calorie diet (adherence to it was also maximum). As for physicians, the most recognized and most recommended preventively was the Mediterranean eating pattern. At the same time, the prevalence and recognition of the DASH diet, which, according to the opinion of the world community, has the most pronounced preventive and therapeutic properties, according to the survey, was low (7.3% of the respondents were aware of this diet). Conclusions. According to the results of this work, it is necessary to consider the possibility of combining three diets (low-calorie, Mediterranean and DASH diets) to achieve the maximum therapeutic and preventive effect while maintaining popularity among patients.

[Evaluation of dentists regulatory systems stress during the provision of dental care according to pulse oximetry data]. / Otsenka napryazheniya regulyatornykh sistem vrachei-stomatologov v period okazaniya stomatologicheskoi pomoshchi naseleniyu po dannym pul'soksimetrii i saturatsii krovi.

OBJECTIVE: To evaluate the status of individual hemodynamic parameters (HR) and respiratory indicators of dentists performing local anesthesia. Material and methods. In the period from April 2019 to December 2019 the determination of heart rate (Heart rate) and blood saturation at 120 doctors aged 25-55 years was performed. The value of blood saturation by non-invasive pulse oximeter technique: SpO2 measurement range 0-99%; heart rate range 18-300 beats per minute. The limit of 95-98% was considered normal. However, we consider it correct to note the introduction of an error of 0.1% due to the constant wearing of a dentist's tight polymer mask. All subjects were preliminarily determined by Robergs-Landvere formula: maximum heart rate (MF)=205.8-(0.685·age). RESULTS: Maximum HR limits for the groups of subjects were 185.6±3.1 beats per minute in the first group; 178.7±3.1 beats per minute in the second group; 171.5±3.4 beats per minute in the third group. In all groups the tendency to decrease blood saturation in case of pain appearance in patients during treatment against the background of block anesthesia, as well as during anesthesia on the mandible was determined. The definition of SpO2 showed a slight downward trend in blood saturation when pain occurs within normal parameters. Thus, the limit of changes in the index against the background of performed local anesthesia on the mandible was 95.2-96.1% and 96.3-96.6% on the maxilla. CONCLUSION: Measurement of arterial oxygen saturation in dentists showed a tendency for a slight decrease in this indicator within the normal range when the patient developed pain. Thus, the limit of changes in the indicator against the background of local anesthesia on the lower jaw was 95.2-96.1%, on the upper jaw - 96.3-96.6%.

Morphological changes in the sphenopalatine ganglion on the background of metabolic disorders in the experiment at rats

The sphenopalatine ganglion occupies a special place in neuropathology and dental neuropathy, accompanied by such pronounced symptoms as "vegetative storm". The aim of the research was obtaining information on the external structure of the sphenopalatine ganglion, the morphometric characteristics of its neurons in norm and in experimental diabetes. The study was carried out on male Wistar rats weighing 260-300 g: with a stereoscopic biological microscope, using ophthalmic instruments, we removed almost the entire gland that was not accompanied by significant bleeding under general anesthesia. Peculiarities of the external structure of the sphenopalatine ganglion of the white rat were studied by macro-micro preparations under a binocular microscope at 50 objects pervaded with silver nitrate, according to Christen-sen
