Today it is important to clarify the features of CAD on the background of concomitant anemia and identify the main risk factors for complications to improve the tactics of this category of patients.\u0000The aim. To investigate the influence of concomitant anemic syndrome on the clinical course of coronary artery disease, frequency and features of the main cardiovascular events.\u0000Materials and methods. The study involved 91 patients with coronary artery disease (42 men and 49 women, age – 70 (49; 93)). All patients were divided into 2 groups: the main group (n = 46) consisted of patients with coronary artery disease with iron-deficiency anemia, the comparison group (n = 45) – patients with coronary artery disease without iron-deficiency anemia. The study of the main cardiovascular events took into account re-hospitalization due to arrhythmic disorders, progression of heart failure (HF), CAD destabilization within the observed period (1 year), as well as death from cardiovascular causes. The data analysis was performed using Statistica 13.0.\u0000Results. During the year, 42 non-fatal cardiovascular events were noted in patients of both groups, however in the main group their total number was 30 (67 %) versus 12 (27 %) in the comparison group (χ2 = 13.603; P < 0.05). The presence of concomitant anemia in CAD patients significantly increased the relative risk of re-hospitalizations (RR = 1.9; 95 % CI 1.230–3.112; P < 0.05). Among the reasons for hospitalization in the main group, HF decompensation prevailed – 17 (57 %) patients, unstable angina – 7 (23 %), arrhythmic disorders – 6 (20 %); in the comparison group, among the reasons for re-hospitalization, 7 (57 %) had HF decompensation, 3 (25 %) had unstable angina, and 2 (17 %) cases had arrhythmic disorders. In total, 9 (19.5 %) deaths were recorded in the main group, while in the comparison group 1 (2.2 %) death was recorded during the year (χ2 = 6.995; P < 0.05). The presence of concomitant anemia in patients with CAD increases the risk of fatal outcome by 8.8 times (RR = 8.8; 95 % CI 1.162–66.685; P < 0.05). The presence of moderate anemia in patients with CAD significantly increases the incidence of combined critical events by 39 % during the year of follow-up compared with mild anemia (χ2 = 12.843; P < 0.05).\u0000Conclusions. The presence of concomitant anemia is associated with a worsened prognosis for patients having coronary artery disease due to an increased risk of non-fatal cardiovascular events that require re-hospitalization during the year of observation, and an increased incidence of death. Increasing severity of anemia is associated with an increase in the frequency of the combined critical event during 1 year of follow-up.","PeriodicalId":41645,"journal":{"name":"Pathologia","volume":"5 1","pages":""},"PeriodicalIF":0.1,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75177932","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 article objective is to illustrate the dynamic changes in the course of AF with the development of CAVB on the example of a clinical case and to discuss the difficulties in timely diagnosis and therapy correction.\u0000Case presentation. A 75-year-old male was diagnosed with a rapid ventricular response form of AF. The onset of CAVB caused the transition from rapid ventricular response form of AF to slow ventricular response form, which was initially accompanied by a subjective improvement in the patient’s condition. As the disease progressed, the patient’s condition worsened due to the development of MAS attacks.\u0000The elderly patients with a permanent form of AF require constant cardiac monitoring by an experienced specialist who has appropriate vigilance in management of patients with arrhythmias, awareness about possible concomitant conduction disorders.\u0000This provides comprehensive cardiac support, including timely pacemaker implantation which gives more options for AF symptoms monitoring and heart rate control, has a positive modifying effect on drug therapy.\u0000Conclusions.

Development of diagnostic criteria for biliary reflux\u0000Materials and methods. The results of treatment of 36 patients with morbid obesity who underwent bypass surgery were studied. The patients are divided into two groups. Clinically modified laparoscopic monoanastomotic gastric bypass surgery was performed in 25 patients (main group). The control group included 11 patients after the standard technique of Roux-en-Y laparoscopic gastric bypass. Inclusion criteria were: persons of both sexes aged 18-60 years with morbid obesity and a body mass index of 40 or more, as well as 35 or more in the presence of comorbid diseases (type 2 diabetes mellitus, arterial hypertension, dyslipidemia, sleep apnea syndrome). In both groups, impedance pH measurements were performed in the postoperative period. Statistical processing was performed using the Statistica 13.0 software package using parametric and nonparametric statistical methods.\u0000 Results: Clinical manifestations of the enterogastric biliary reflex were found in both groups; in addition, clinical manifestations of the corresponding symptoms were noted by patients of both groups. The analysis of daily pH-metry in the studied groups showed that in the esophagus the time with pH <4 in the main group 2.83 (1.55; 3.95)% 3.00 (2.30; 3.50)% in the control group, time with pH 4-6.9 (physiological for the esophagus) 92.40 (90.65; 94.20)% and 94.10 (89.80; 95.50)%, respectively, time with pH> 7 (weak alkaline) was 4.80 (3.45; 5.85)% and in the control group 2.90 (1.20; 7.20)%. There was no statistically significant difference in these indicators (p> 0.05). Conclusions. Monoanastomotic gastric bypass surgery in the modification of the clinic has the same positive properties as the Rouen-Wye technique, allowing you to avoid the risks associated with possible pathological reflux of bile into the esophagus. Patients who have undergone mini-gastric bypass surgery require a thorough examination with fibrogastroscopy in combination with pH impedance measurement at least 1 time per year in order to determine biliary reflux and morphological changes both in the lumen of the esophagus and in the stomach stump. The level of quality of life of patients after surgery in the control group and the main group does not significantly differ, as evidenced by the results of the questionnaire survey using the GERG Q questionnaire, which indicates the effectiveness of the methodology of laparoscopic monoanastomotic gastric bypass surgery modified in the clinic.

Astroglia, the most abundant cell population within the brain, plays the critical role in control of all kinds of homeostatic processes, thereby regulating the adaptive reactions of the brain to various challenges. Astroglia are highly heterogenous across the brain regions, therefore, damaging factors stimulate heterogenous astroglial reactivity and response in different brain regions.\u0000The aim of this study was determining immunohistochemical features of GFAP expression in various brain regions in the model of rodent experimental sepsis.\u0000Materials and methods. The experiment was performed in Wistar rats: control group of 5 sham-operated rats and the main group of 20 rats subjected to cecum ligation and puncture (CLP) procedure. The immunohistochemical study of GFAP expression in the sensorimotor cortex, subcortical white matter, hippocampal, thalamic and caudate nucleus/putamen regions was performed from 20 to 48 hours of the postoperative period.\u0000Results. Starting from the 12th hour after CLP, animals began display progressive increase in signs of periorbital exudation, piloerection, fever-/hypothermia, diarrhea, social isolation, lethargy, and respiratory impairment. In the period of 20–38 hours, 9 animals showed expressed previously listed symptoms and were euthanized (CLP-B – lethal group), 11 rats survived until 48 hours of the experiment (CLP-A – survived group). In the lethal group, starting from 20 to 38 hours after the CLP procedure, a significant (relative to control) regionally-specific dynamic increase in the level of GFAP expression was observed in the brain: in the cortex – by 465 %, in the subcortical white matter – by 198 %, in the hippocampus – by 250 %, from the 23rd hour – in the caudate nucleus/putamen by 18 %. In the thalamus, no significant changes in the level of GFAP expression were observed. In the cortex and hippocampus of survived animals, 48 h after CLP, higher values of GFAP expression were observed comparing to the group of non-survived animals.\u0000Conclusions. Under conditions of the experimental SAE, an early dynamic increase in the astroglial reactivity was observed in the cortex, hippocampus, white matter, and caudate nucleus/putamen of the brain with the most significant increase of indicators in the cortex and hippocampus, which potentially indicates relatively more vulnerable areas of the brain to damaging factors, as well as places of the most active intercellular interaction in the condition of systemic inflammation. Higher values of GFAP expression in the cortex and hippocampus of survived animals at 48 hours of the experiment, compared with indicators of non-survived group, indicate increased astroglial reactivity in these brain regions at the noted time period, accompanied by relatively more favorable clinical course of the disease.\u0000 ","PeriodicalId":41645,"journal":{"name":"Pathologia","volume":"142 1","pages":""},"PeriodicalIF":0.1,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81779041","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}

We analyzed 41 case histories and results of pathological-anatomical examination of patients who were died of COVID-19 during 2020.\u0000Results. The lethal outcome of COVID-19 disease was recorded at day 22 (16; 27) of the disease. Among the dead, there is a high percentage of men (73.2 %), early old age and middle old age patients (75.6 %) with comorbid pathology (92.7 %). Early lung damage with COVID-19 in the deceased was determined by pronounced interstitial and interstitial-alveolar edema, the presence of erythrocyte stasis in the pulmonary microvessels, blood clots and hypoperfusion leukocyte stasis, as well as the presence of erythrocytes in the alveoli. Bilateral polysegmental subtotal viral pneumonia in 90.2 % of dead patients was characterized by significant edema and thickening of the alveolar walls with their moderate infiltration by lymphocytes, focal peribronchial and perivascular inflammatory polymorphonuclear infiltration, multiple and small exfoliated alveolar epithelium (87.8 %), as well as metaplasia of a few alveolocytes preserved on the luminal surface of the alveoli (82.9 %). Every tenth person who died of COVID-19 had signs of secondary bacterial microflora. In 85.4 % of patients who died on day 22–27 of the disease focal or sublobar pneumofibrosis was diagnosed. In those who died due to COVID-19, multiorgan failure was characterized by focal necrosis of the renal tubular epithelium (73.2 %), focal lymphocytic-leukocyte infiltration (12.2 %) and renal microvascular thrombosis (17.1 %), focal centro-lobular necrosis (90.2 %) and focal lymphocytic-leukocyte infiltration of lobes (7.3 %) of the liver. Thrombotic complications were confirmed in 22.0 % of deceased patients: ischemic cerebral infarction, transmural myocardial infarction, pulmonary embolism, deep vein thrombosis of the lower extremities under the pathology. These thrombotic complications were not diagnosed during life in all patients. The majority of deaths due to COVID-19 had morphological signs of chronic cardiovascular pathology. Ischemic heart disease and hypertension during the life of patients were not diagnosed in all cases.\u0000Conclusions. Early lung damage in COVID-19 in the deceased was determined by pronounced interstitial-alveolar edema, blood clots and leukocyte stasis in microvessels, less often – the presence of “hyaline membranes”.

The paper presents the data on examination of 70 patients with AH of 2–3 degrees (46 patients with AO and 24 patients without obesity – with normal body weight (NBW)). The control group included 20 apparently healthy individuals with NBW. The patients underwent detailed standard clinical, laboratory and instrumental examination. Determination of the quantitative composition of GM was carried out by the method of polymerase chain reaction with hybridization-fluorescence detection of results in real time using the test system “COLONOFLOR-16 (biocenosis)” (“ALFA-LAB”). In this work, a statistical analysis of the obtained data was carried out using standard methods and Microsoft Excel 17.0.\u0000Results. A significant change in the composition of GM were found in patients with AH, which proceeds against the background of AO, in comparison with apparently healthy individuals and with patients with AH without obesity (with NBW). In the group of AH patients with the presence of AO, significant decrease in the number of Lactobacillus spp., Bifidobacterium spp., Faecalibacterium prausnitzii and Аkkermansia muciniphila was found in comparison with apparently healthy individuals. The number of Faecalibacterium prausnitzii and Аkkermansia muciniphila in these patients was also significantly lower than in hypertensive patients with NBW.

Pathomorphological changes in the placenta in the coronavirus disease COVID-19 depended on the duration of the post-COVID interval (the time interval from the diagnosis of COVID-19 and the moment of delivery), due to the sequential change in the phases of the inflammatory process: alteration, exudation and proliferation, followed by fibrosis. The formation of acute placental insufficiency in coronavirus disease COVID-19, diagnosed up to 1–6 weeks to delivery, is associated with the development of severe disorders of circulation and acute exudative inflammatory reactions of varying severity. The formation of chronic placental insufficiency is associated with the proliferative stage of inflammation. These changes lead to the development of fibrosis in the wall of arterioles and intervillous space. The most significant structural changes in the placenta, leading to placental insufficiency, were observed in group 2 – at the time of infection in the period from 23–33 weeks of pregnancy.

The ultrasound study of vessels of paraurethral glands, when Doppler method is used according to the suggested methodology, gives the opportunity not only to identify its anatomical structure, but also to determine its types. In CDC the increase of diameter of vessels and the optimization of vessels image in the area of paraurethral glands in case of sexual stimulation were marked.","PeriodicalId":41645,"journal":{"name":"Pathologia","volume":"33 1","pages":""},"PeriodicalIF":0.1,"publicationDate":"2021-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75035090","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}

Histological changes of the esophageal mucosa in RE have been described in adults and children, but there are only isolated studies that describe the morphological features of the esophageal mucosa in combined pathology, taking into account the severity of asthma.\u0000The aim is to study the histological and immunohistochemical features of the esophageal mucosa in children with asthma combined with reflux esophagitis.\u0000Materials and methods. In 43 children aged 6–17 years with RE and severe asthma (group 1), with mild/moderate asthma (group 2) and without asthma (group 3), mucosal biopsies from the distal and proximal esophagus were examined by histolo­gical and immunohistochemical methods. Immunohistochemical research was performed in serial paraffin sections according to standard protocols using monoclonal antibodies to Ki-67, MMP-9, VEGF, BCL-2, IgE and CD68.\u0000Results. In children with asthma combined with RE, the structural changes of the esophageal mucosa differed depending on the severity of asthma. Severe basal epithelial hyperplasia was registered in 92.31 % of children in group 1, and its frequency was significantly different from children in groups 2 and 3. A characteristic feature of children with asthma and reflux eso­phagitis was dyschronosis, which was characterized by foci of hypo- and hypertrophy of basal layer cells (92.31 % of children in group 1 and 37.50 % of children in group 2). Severe elongation of the “papillae” was found only in 38.46 % of children in group 1. Immunohistochemical features of the esophageal mucosa of children with asthma and reflux esophagitis revealed the expression of Ki-67 antigen, IgE and a weak macrophage response (CD68), the severity of which differed from children with reflux esophagitis without asthma.\u0000Conclusions. Morphological changes in the esophageal mucosa of children with reflux esophagitis and asthma differ from children with reflux esophagitis without asthma in the presence of severe epithelial damage, dyschronosis of changes, severe elongation of the “papillae”, pronounced cell proliferation (Ki-67) and local IgE expression.","PeriodicalId":41645,"journal":{"name":"Pathologia","volume":"15 1","pages":""},"PeriodicalIF":0.1,"publicationDate":"2021-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81168481","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}
