Thyrotoxic atrial fibrillation (TAF) genesis does not exclude a genetic component due to the difference in thyroid hormones effects on the cardiovascular system in similar patients. According to genomewide association studies (GWAS), the first locus associated with non-thyrotoxic atrial fibrillation (AF) was locus 4q25, and the first single-nucleotide polymorphisms in it identified as risk factors for AF were polymorphisms rs2200733 and rs10033464. Their connection with TAF remains unclear.Objective. To investigate the possible association of the two single nucleotide polymorphisms rs2200733 and rs10033464 with TAF.Design and methods. The association of TAF and other thyrotoxic cardiomyopathy manifestations with the studied polymorphisms was examined in a sample of 150 patients with Graves’ disease and overt thyrotoxicosis, 18.7 % of whom had TAF. Genotyping was preformed using real time PCR.Results. A significant predominance of TT genotype for both polymorphisms was revealed: p=0.038 for rs10033464, p<0.001 for rs2200733. TT genotype frequency in TAF patients compared with non-TAF participants: 7.4 % vs 1.6 % for rs10033464, 17.9 % vs 0.8 % for rs2200733. When assessing the frequency of genotypes depending on the presence of other thyrotoxic cardiomyopathy manifestations, TT genotype was more common in patients with ventricular premature beats, p=0.001.Conclusion. TT genotype of rs2200733 and rs10033464 polymorphisms at 4q25 locus is associated with a higher incidence of TAF and ventricular extrasystole in thyrotoxic patients.","PeriodicalId":89863,"journal":{"name":"Translational medicine (Sunnyvale, Calif.)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45966467","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}

A multislice computed tomography of the chest with contrast enhancement, serological diagnosis and histological examination and subsequent surgical treatment of a 6-year-old patient were performed.Results. A case of cystic echinococcosis of the lungs in a 6-year-old boy is presented. Echinococcosis was diagnosed at the stage of a large diameter cyst during chest X-ray to exclude pneumonia. Surgical treatment was performed. The decrease in titers of antiparasitic antibodies in dynamics after the operation allowed to conclude that the patient had recovered. The presented clinical case demonstrates a typical error in the diagnosis of pulmonary echinococcosis. Cystic echinococcosis is a rare pathology in the Arkhangelsk region (up to 4 per year). This situation leads to late diagnosis of this helminthiasis. The main mistake in the diagnosis was the lack of alertness in relation to echinococcosis and, as a result, the establishment of an incorrect diagnosis — pneumonia.Conclusions.

So far, only few studies reported the results of endovascular correction of the atherogenic process in the infrarenal aorta.Objective. To present a clinical case of hybrid revascularization of the aortofemoral segment in a patient with ischemic heart disease.Design and methods. A 68-year-old patient with Leriche’s syndrome underwent ultrasound of the brachiocephalic arteries, coronary angiography, and multispiral computed tomography with angiography.

Given the critical ischemia of the lower extremities and comorbidities, a hybrid surgical intervention was performed: endarterectomy from the femoral arteries and endovascular recanalization of the occlusion of the aortoiliac segment using the “kissing stents” technique.Conclusions. The requirements for equipment and experience of the surgical team limit the widespread use of hybrid correction of an occlusive lesion of the infrarenal aorta. The lack of randomized trials creates uncertainty in the choice of revascularization tactics. In the framework of this clinical case, the effectiveness of hybrid surgery in the treatment of a patient with multifocal atherosclerosis has been proven.","PeriodicalId":89863,"journal":{"name":"Translational medicine (Sunnyvale, Calif.)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47143149","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}

Today, the method of analyzing the spectrum of heart rate variability (HRV) for determining the sympathetic-vagal balance due to its simplicity and non-invasiveness has become widespread both in clinical practice and in experimental studies. The article analyzes the results of our own and literary studies of influence of various effects on hemodynamic parameters, the level of circulating catecholamines, sympathetic nervous activity, the baroreceptor reflex, and also on the components of the HRV spectrum (LF (low frequency), HF (high frequency) and LF/HF). Often different authors under the same impact register different changes. Reasons for this include different doses of drugs, nature/strength of exposure (for stress and exercise), time between drug administration and registration. In addition, the effect of some drugs can be enhanced in the case of pathology, such as hypertension. Based on the comparison of the vectors of changes in the studied parameters, we concluded that, using the frequency analysis of HRV, it is necessary to draw a conclusion about the sympatho-vagal balance with great care due to the ambiguous nature of LF component, but HF component gives information of the tone of the vagus with sufficient accuracy.","PeriodicalId":89863,"journal":{"name":"Translational medicine (Sunnyvale, Calif.)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48133524","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}
