[New opportunities of renal denervation].

Radiofrequency renal artery denervation (RND) was introduced as a method of interventional treatment of resistant hypertension almost ten years ago. The first studies demonstrated the effectiveness of this procedure. This has led to growing interest in this area and the rapid development of the method. However, the results of the first randomized trial of SYMPLICITY HTN-3 questioned the role of RND in the treatment of resistant hypertension, this fact conducted to the decrease in the recommendation class and level of evidence in the Guidelines of the European Society of Cardiology and the European Society of Hypertension in 2018. To date, the medical community is actively discussing the results of recently published trials such as SPYRAL HTN-OFF MED, SPYRAL HTN-ON MED, RADIANCE-HTN SOLO and RADIOSOUND-HTN.

[The spread of Klebsiella in obstetrical hospitals and the biological properties of the isolated strains]. / Rasprostranenie klebsiell v akusherskikh statsionarakh i nekotorye biologicheskie svoistva vydelennykh shtammov.

Examination of 278 newborn infants, parturients, and medical personnel in two maternity hospitals revealed a high level of Klebsiella colonization of all examined biotopes of infants (the nasal cavity in up to 36.5% of cases) and the skin of the mammary glands of nursing mothers (in 36.2% of cases). In the intestine and the nasal cavity of parturient women and medical personnel Klebsiella could be detected 3-10 times more often than in the same biotopes of nonhospitalized pregnant women. From 254 objects of the hospital environment Klebsiella were isolated in 9.05% of cases. The possibility of the transmission of Klebsiella in hospitals by patients with inflammatory processes in their genitals were established. The diversity of the serological picture of strains of most K-serovars and a short period of their isolation were shown. In one hospital serovar K10 with some features of a "hospital" strain was isolated. The strains under study were sensitive to aminoglycosides, cephamesine, chlorhexidine, but resistant to semisynthetic penicillins and chloramine.

[Biological characteristics of Proteus strains isolated from water sources in the Azerbajiani SSR]. / K biologicheskoi kharakteristike shtammov Proteus, vydelennykh iz vodoistochnikov v Azerbaidzhanskoi SSR.

Biological characteristics of 102 Proteus strains isolated from the water bodies is given. The strains studied were referred to Pr. mirabilis, more rarely to Pr. vulgaris; about half of the cultures deviated from these biological types by the signs of indol formation and maltose fermentation. Proteus of groups O3, O5, O13, O23, and O30 were revealed in studying the serological characteristics. All the cultures were polyresistant, nonbacteriocinogenic; most of them were sensitive to the wide colicine spectrum. One strain produced a cytopathogenic action on the tissue culture.

[Comparative study of the antibiotic sensitivity of Proteus hauseri bacteria belonging to different serological groups]. / Sravnitel'noe izuchenie chuvstvitel'nosti k antibiotikam u bakterii Proteus hauseri, prinadlezhashchikh k razlichnym serologicheskim gruppam

Sensitivity to 9 antibiotics of 1040 strains of Proteus belonging to the serological groups 03, 05, 06, 07, 010, 011, 013, 023, 024, 026, 027, 028 and 030 was studied. It was found that the above strains were sensitive and highly sensitive to the aminoglycosides and streptomycin, slightly sensitive to levomycetin and resistant to tetracyclines, erythromycin and penicillin. All the strains were polyresistant and 99.6 per cent of them were resistant to 4--9 antibiotics. Ten types of resistance were found. Proteus strains with the resistance type PETOtCht were most common. No relation between the occurrence of the strains of various serological groups and the character and level of their resistance to the antibiotics was found.
