The aim is to determine the possibility of organizing the architectural environment as a system based on the fundamental principle of a single criterion helps to avoid errors arising from the integrated multi-factor approach to the problem under study.Methods. Architectural tourism and recreation system (ATRS) is a part of demoekosystem and has all its inherent properties.Results. Applying systematic approach to construction of architectural tourism and recreation system helps to identify the main factors that affect the system and form its boundaries. The identified properties and principles of interaction between the elements allow to build the ontological (essential), functional and mathematical models.Main conclusions. System approach allows to solve such important economic problems as tourism development in the Russian Federation

Management of a Female Patient with Irritable Bowel Syndrome and Somatoform Disorder

Aim: to demonstrate the management of a patient with somatization disorder and irritable bowel syndrome.Key points. A 41-yo female patient was admitted with complains of spastic lower abdomen pain, hard stool once every 1–2 days under laxative treatment (macrogol), bloating, anxiety, waiting for confirmation of a life threatening illness, internal stress, difficulty in falling asleep, shallow sleep. Has a long history of disease, characterized by the appearance of a variety of somatic symptoms (headache, tachycardia, joint pain, stool disorders, abdominal pain, etc.) during periods of emotional tension, lack of data suggesting organic disease. No abnormal changes were detected in examination at the clinic (complete blood count, serum chemistry tests, urinalysis or fecal tests, hydrogen and methane breath tests with lactulose, abdominal ultrasound, esophagogastroduodenoscopy, colonoscopy). With the prior agreement of patient, she was consulted by a psychiatrist and diagnosed with somatization disorder and mild anxiety disorder. On discharge from hospital recommended cognitive-behavioral therapy, continue taking macrogol, as well as treatment with Kolofort. After 3 months of complex treatment, there was a significant decrease in the severity of both the symptoms of irritable bowel syndrome and anxiety disorder.Conclusion. For patients whose complaints meet the diagnostic criteria for IBS, a two-stage differential diagnosis may be justified: at the first stage, differentiation of IBS and organic diseases of the gastrointestinal tract is carried out; at the second stage - IBS and somatization disorder. Kolofort can be the drug of choice both in patients with IBS and the pharmacological part of therapy in patients with somatization disorder

Direct and Indirect Methods for Studying Human Gut Microbiota

Aim: To review the main methods of intestinal microbiota studying.Key points. Currently, molecular genetic methods are used mainly for basic research and do not have a unified protocol for data analysis, which makes it difficult to implement them in clinical practice. Measurement of short chain fatty acids (SCFA) concentrations in plasma provides the data, which can serve as an indirect biomarker of the colonic microbiota composition. However, currently available evidence is insufficient to relate the obtained values (SCFA levels and ratio) to a particular disease with a high degree of certainty. Trimethylamine N-oxide (TMAO) levels in the blood plasma and urine can also reflect the presence of specific bacterial clusters containing genes Cut, CntA/CntB and YeaW/YeaX. Therefore, further studies are required to reveal possible correlations between certain disorders and such parameters as the composition of gut microbiota, dietary patterns and TMAO concentration. Gas biomarkers, i.e. hydrogen, methane and hydrogen sulphide, have been studied in more detail and are better understood as compared to other biomarkers of the gut microbiome composition and functionality. The main advantage of gas biomarkers is that they can be measured multiple times using non-invasive techniques. These measurements provide information on the relative proportion of hydrogenic (i.e. hydrogen producing) and hydrogenotrophic (i.e. methanogenic and sulfate-reducing) microorganisms. In its turn, this opens up the possibility of developing new approaches to correction of individual microbiota components.Conclusions. Integration of the data obtained by gut microbiota studies at the genome, transcriptome and metabolome levels would allow a comprehensive analysis of microbial community function and its interaction with the human organism. This approach may increase our understanding of the pathogenesis of various diseases as well open up new opportunities for prevention and treatment

New Coronavirus Infection (COVID-19) and Digestive System

Aim. The study reviews current evidence on digestive system lesions provoked by the new COVID-19 coronavirus infection.Key points. Alongside the destructive impact on respiratory system, COVID-19 manifests itself in gastrointestinal symptoms (nausea, vomiting, diarrhoea) that may precede respiratory signs and prevail in the clinical picture of infection. Patients with chronic inflammatory bowel diseases receiving immunosuppressive therapy are at elevated risk of severe COVID-19 progression. The new coronavirus infection may induce liver damage with increased transaminase activity.Conclusion. Association of digestive system lesions with COVID-19 remains understudied and requires further research

The Effectiveness of Add-on Treatment with Nutraceutical

Aim: evaluation of the effectiveness of the nutraceutical “Standard Zdorovia: Gastro” (“SZ Gastro”) in the treatment of patients with irritable bowel syndrome (IBS).Materials and methods. 52 patients (62 % women) diagnosed with IBS and IBS in combination with functional dyspepsia (FD) were included in the study and divided into two groups. Both groups received basic therapy according to the guidelines. The experimental group received as add-on the nutraceutical “SZ Gastro” (containing a standardized amount of menthol, gingerol and D-limonene); patients in the control group — placebo. The duration of the study was 30 days. The severity of somatic symptoms was assessed with the 7×7 questionnaire. Emotional state was assessed with the Four Dimensional Distress, Depression, Anxiety, and Somatization Questionnaire (4DSQ).Results. Patients of the experimental and control groups did not differ from each other either in terms of demographics, basic treatment, or in the severity of symptoms at the beginning of the study.The effectiveness of the treatment in the patients, who received add-on “SZ Gastro” was significantly higher than in the patients of the control group: in the control group the percentage of improvement of somatic symptoms was 22.35 %, in the experimental group it amounted to 49.18 % (χ2 = 15.9; p = 0.0001). The percentage of patients with significant decrease of emotional disturbances was also higher in the experimental group: distress (χ2 = 18.7; p = 0.0000), anxiety (χ2 = 6.9; p = 0.0097) and somatization (χ2 = 14.99; p = 0.0001). No significant side effects were registered in any of the groups.Conclusions. Add-on of nutraceutical “SZ Gastro” to basic treatment is safe and significantly increases effectiveness of the therapy in the patients with IBS and IBS in combination with PD

АКТУАЛЬНЫЕ ПРОБЛЕМЫ ТУБЕРКУЛЕЗА У ПОДРОСТКОВ ИЗ ОЧАГОВ ТУБЕРКУЛЕЗНОЙ ИНФЕКЦИИ

The article characterizes respiratory tuberculosis in adolescents exposed to tuberculous infection. Exposure to tuberculosis in the family or when contacting close relatives makes the biggest contribution into development of the disease unless the patient is isolated from those exposed. Advanced and severe forms of tuberculosis with bacillary excretion are detected, compromising the life quality of adolescents. The main causes of late diagnostics are poor performance of TB services, primary medical units, low level of health education aimed at the increase of motivation to have planned medical examinations in the general population and to take relevant sanitary and hygienic measures in the sites of infection. Adolescents from the sites with bacillary excretion, and, first of all, if multiple or extensive drug resistant tuberculosis is detected, are to be considered a high priority group facing the risk to develop the disease with more frequent monitoring and deeper examination. In primary medical units, should any sings typical of tuberculosis be presented, it is sensible to add skin tests (Mantoux test and test with tuberculous recombinant allergen) to the minimum diagnostic procedures. Organizational, methodical and health education activities in the sites of infection are to be improved.Дана характеристика туберкулеза органов дыхания у подростков из контакта с больным туберкулезом. Набольшее значение для развития заболевания имеет контакт в семье и с близкими родственниками без изоляции контактирующих лиц от больного. Выявляются тяжелые, распространенные процессы с бактериовыделением, которые снижают качество жизни заболевшего подростка. Основные причины поздней диагностики – недостатки в работе противотуберкулезной службы, первичной медико-санитарной помощи (ПМСП), низкий уровень санитарно-просветительной работы по повышению мотивации населения к плановым обследованиям и соблюдению санитарно-гигиенических мероприятий в очаге. Подростки из очагов с бактериовыделением, в первую очередь при обнаружении микобактерий туберкулеза с множественной/широкой лекарственной устойчивостью, должны рассматриваться как приоритетная группа риска развития заболевания с более частым мониторингом, углубленным обследованием. В учреждениях ПМСП при наличии клинических признаков, таких же как при туберкулезе, целесообразно включить в диагностический минимум кожные иммунологические тесты (проба Манту и проба с аллергеном туберкулезным рекомбинантным). Необходимо совершенствование работы организационно-методической и санитарно-просветительной работы в очагах

Colorectal Cancer in Patient with Functional Gastrointestinal Symptoms

Aim. A clinical observation to highlight the importance of detailed examination in patients with functional gastrointestinal symptoms.Key points. A 28-yo female patient was admitted with complains of left ileal pain, abdominal distention and up to 4-day stool delay. The complaints had long been interpreted as clinical manifestations of irritable bowel syndrome. No significant abnormalities were revealed in outpatient check-up (general and biochemical blood panels, stool test, abdominal ultrasound, oesophagogastroduodenoscopy). Colonoscopy was performed on admission, with diagnosis of rectal adenocarcinoma. The patient had a prompt surgical intervention, repeated courses of polychemotherapy and is currently followed by an oncologist and coloproctologist. No relapse signs have been reported.Conclusion. Patients with the complaints satisfying the Rome Criteria Revision IV for functional gastrointestinal diseases should have a thorough examination as per recommendations of the Russian Gastroenterological Association and Russian Association of Coloproctologists

Clinical Recommendations of the Northwest Society for Enteral and Parenteral Nutrition, Interregional Association for Emergency Surgery, Russian Gastroenterological Association, Union of Rehabilitation Therapists of Russia and Russian Transplantation Society on Diagnosis and Treatment of Short Bowel Syndrome-Associated Intestinal Failure in Adults

Aim. Current clinical recommendations address the epidemiology, causes, clinical manifestations and pathogenesis of possible immediate and long-term complications, as well as the problematic issues related to treatment and rehabilitation of adult short bowel syndrome patients.Key points. Short bowel syndrome (SBS) is a symptom complex of impaired digestion caused by the reduction of small intestine absorptive surface and manifested by intestinal failure (IF) of various severity (maldigestion and malabsorption) developing into malnutrition and systemic somatogenic disorders. The vital strategic aspects of its treatment are the personalisation of liquid, macro- and micronutrients consumption as well as avoidance of intestinal failure- and parenteral nutrition-associated complications. Various nutritional support regimes and the indications for infusion therapy and maintenance parenteral nutrition are considered in this patient category, also in outpatient settings. To mitigate the dependence on intravenous fluid- and nutrient administration and attain enteral autonomy in SBS-IF patients, the use of recombinant glucagon-like peptide-2 (GLP-2) is justified as exerting a pronounced trophic effect on the epithelial regenerative potential as well as structural and functional adaptation of intestinal mucosa. The SBS-IF patients prescribed with home parenteral nutrition and/or their caregivers should be trained in a special programme that covers the catheter care, preparation of infusion solutions and nutrient mixture container, infusion pump operation as well as the prevention, recognition and management of complications. The main referral indications for small bowel transplantation (SBT) are: fast-progressing cholestatic liver disease-complicated irreversible intestinal failure; thrombosis of two or more central venous conduits used for parenteral nutrition; recurrent catheter-associated bloodstream infection.Conclusion. Current recommendations on diagnosis and treatment as well as the developed criteria of medical aid quality assessment are applicable at different levels of healthcare
