Comprehensive geriatric assessment in elderly and senile patients with cardiovascular diseases. Expert opinion of the Russian Association of Gerontologists and Geriatricians.

Senile asthenia syndrome (SAS) is a geriatric syndrome characterized by age-associated decline of the physiological reserve and function in multiple systems, which results in higher vulnerability to effects of endo- and exogenous factors and a high risk of unfavorable outcomes, loss of self-sufficiency, and death. Generally, SAS is observed in elderly patients with comorbidities. In cardiovascular diseases, SAS is associated with a poor prognosis, including a higher incidence of exacerbation and death both during acute events and in chronic disease. However, SAS is often not taken into account in developing diagnostic and therapeutic programs for managing elderly patients with cardiovascular diseases (CVD). This article analyzes available scientific information about SAS, algorithms for SAS diagnosis, and the scales that may be useful in developing individual plans for management of elderly patients with CVD.

Infective Endocarditis in Moscow General Hospital: Clinical Characteristics and Outcomes (Single-Center 7 Years' Experience).

AIM: to investigate clinical properties of course and outcomes of infective endocarditis (IE) depending on source of infection, to find predictors of mortality in a Moscow general hospital. MATERIALS AND METHODS: We included in this study 176 patients with definite and possible infective endocarditis (the Duke criteria), admitted in our hospital in 2010-2017. Patients were divided in three groups according to source of infection. All patients underwent standard clinical and laboratory assessment, echocardiography, blood culture test combined with blood PCR with sequencing. Inhospital and 1-year outcome were evaluated. RESULTS: Among 176 patients with IE 65.3 % were men (median age 57 [35-72] years), most patients (n=149, 84.7 %) had native valve IE. Etiological factor was identified in 127 (72.2 %) cases. Gram-positive infective agents prevailed (54 %). Surgery in active phase of the disease was performed in 30 (17 %) patients. Among patients with healthcare-associated IE (n=76, 43.9 %) prevailed those older than 60 years, with high Charlson comorbidity index, with culture-negative IE, and complicated clinical course (mainly progressing heart failure). Patients with intravenous drug use associated IE (n=50, 28.4 %) had low Charlson index, association with hepatitis C viral infection, involvement of tricuspid valve with big vegetations, high frequency of embolic complications, and low inhospital mortality. Group of patients with community acquired IE (n=50, 28.4 %) more often had uncommon causative microorganisms, and had better long-term outcome. In-hospital mortality was 30.1 % (n=53) mostly due to sepsis with multi-organ failure, and heart failure. Risk factors of inhospital death were history of cardiovascular diseases, old age, kidney damage, methicillin-resistant Staphylococcus aureus (MRSA) infection, uncontrolled infection, and embolic events. Risk factors of 1-year mortality were history of stroke, and heart failure as IE complication. Independent predictors of in-hospital death were MRSA infection (odds ratio [OR] 50.32, 95 % confidence interval [CI] 1.66-213.92; p=0.002), persistent infection (OR 18.6, 95 %CI 5.37-64.40; p=0.001), duration of fever >7 days after initiation of antibacterial therapy (OR 13.41, 95 %CI 3.51-51.24; p=0.001); and of death during first year - history of cerebral infarction (OR 4.39, 95 %CI 1.32-14.70; p=0.016)), and heart failure as IE complication (OR 8.1, 95 %CI 1.97-67.09; p=0.016). Among patients subjected to surgery there were no fatal outcomes during 1 year after hospital discharge, while among conservatively treated patients were 21 (14.4 %) deaths (p<0.009). CONCLUSION: Main clinical features of IE course in patients urgently admitted to a general hospital was dominance of healthcare-associated  IE among patients, who were older than 60 years with severe comorbidities. These patients had more complications and worse outcome. Modeling of prognosis identified uncontrolled infection as key factor of unfavorable outcome. Surgery significantly reduced long-term mortality.

[Infective endocarditis: Importance of molecular biological techniques in etiological diagnosis]. / Infektsionnyi endokardit: znachenie molekulyarno-biologicheskikh metodov v etiologicheskoi diagnostike.

AIM: To investigate the specific features of conventional bacteriological methods and current molecular biological techniques for the etiological diagnosis of infective endocarditis (IE). SUBJECTS AND METHODS: Examinations were made in 53 patients treated at City Clinical Hospital Sixty-Four, Moscow Healthcare Department, in 2012-2015 who underwent simultaneous bacteriological and molecular biological (polymerase chain reaction (PCR) or PCR with further sequencing) examinations of blood or resected cardiac valve tissues. RESULTS: The investigation included 53 patients (31 men; median age, 62 years) with IE (Duke 2009); its primary form was observed in 32 (60.4%) patients. Blood bacteriological tests and PCR assays were positive in 28 (52.8%) and 34 (64.2%) patients, respectively. There were concordant results in 21 of the 28 positive blood culture cases and discordant results in 7 (25%); at the same time 3 cases showed a compete discordance in the detected causative agents (the growth of Enterococcus spp. was revealed by bacteriological examination and that of Staphylococcus spp., Streptococcus spp., and Escherichia coli by DNA PCR) and a pathogen could not be identified by DNA PCR in 4 patients who had positive blood bacteriological results. The positive PCR results for cocci and fungi were obtained in 10 of the 25 (47.2%) examinees with culture-negative IE. Rare causative agents were not revealed. The tissues obtained from 8 resected damaged heart valves displayed a wider spectrum of pathogens than did blood samples, which was associated with the formation of bacterial films. CONCLUSION: The etiological agent of IE was revealed in venous blood by bacteriological examination in 52.8% of the examinees, by PCR in 64.2%, and by either in 71.7%. There were concordant and discordant results in 67.9 and 32.1% of the patients, respectively; among whom 18.9% were found to have pathogen DNA revealed by PCR in culture-negative IE.
