Rehabilitation after COVID-19. Resolution of the International Expert Council of the Eurasian Association of Therapists and the Russian Society of Cardiology

By the middle of 2021, the official global number of coronavirus disease 2019 (COVID-19) patients was close to 230 million, but the number accounting for asymptomatic patients was much higher. Consequences and rehabilitation after COVID-19 are of particular interest and raise many controversial and unresolved issues. On May 18, 2021, the Eurasian Association of Therapists organized an international panel of experts to analyze challenges associated with the post-COVID-19 period. This panel aimed to develop approaches to identify gaps in the discussed issues. This interdisciplinary team of leading experts reviewed the current literature and presented their data to formulate practical guidance on management of patients after COVID-19. The panel of experts also presented recommendations on how to implement the gained knowledge into health care practices

Quorum Sensing Signaling Molecules Produced by Reference and Emerging Soft-Rot Bacteria (Dickeya and Pectobacterium spp.)

International audienceBACKGROUND: Several small diffusible molecules are involved in bacterial quorum sensing and virulence. The production of autoinducers-1 and -2, quinolone, indole and γ-amino butyrate signaling molecules was investigated in a set of soft-rot bacteria belonging to six Dickeya or Pectobacterium species including recent or emerging potato isolates. METHODOLOGY/PRINCIPAL FINDINGS: Using bacterial biosensors, immunoassay, and chromatographic analysis, we showed that soft-rot bacteria have the common ability to produce transiently during their exponential phase of growth the N-3-oxo-hexanoyl- or the N-3-oxo-octanoyl-l-homoserine lactones and a molecule of the autoinducer-2 family. Dickeya spp. produced in addition the indole-3-acetic acid in tryptophan-rich conditions. All these signaling molecules have been identified for the first time in the novel Dickeya solani species. In contrast, quinolone and γ-amino butyrate signals were not identified and the corresponding synthases are not present in the available genomes of soft-rot bacteria. To determine if the variations of signal production according to growth phase could result from expression modifications of the corresponding synthase gene, the respective mRNA levels were estimated by reverse transcriptase-PCR. While the N-acyl-homoserine lactone production is systematically correlated to the synthase expression, that of the autoinducer-2 follows the expression of an enzyme upstream in the activated methyl cycle and providing its precursor, rather than the expression of its own synthase. CONCLUSIONS/SIGNIFICANCE: Despite sharing the S-adenosylmethionine precursor, no strong link was detected between the production kinetics or metabolic pathways of autoinducers-1 and -2. In contrast, the signaling pathway of autoinducer-2 seems to be switched off by the indole-3-acetic acid pathway under tryptophan control. It therefore appears that the two genera of soft-rot bacteria have similarities but also differences in the mechanisms of communication via the diffusible molecules. Our results designate autoinducer-1 lactones as the main targets for a global biocontrol of soft-rot bacteria communications, including those of emerging isolates

Clinical features of post-COVID-19 period. Results of the international register “Dynamic analysis of comorbidities in SARS-CoV-2 survivors (AKTIV SARS-CoV-2)”. Data from 6-month follow-up

Aim. To study the clinical course specifics of coronavirus disease 2019 (COVID-19) and comorbid conditions in COVID-19 survivors 3, 6, 12 months after recovery in the Eurasian region according to the AKTIV register. Material and methods.The AKTIV register was created at the initiative of the Eurasian Association of Therapists. The AKTIV register is divided into 2 parts: AKTIV 1 and AKTIV 2. The AKTIV 1 register currently includes 6300 patients, while in AKTIV 2 — 2770. Patients diagnosed with COVID-19 receiving in- and outpatient treatment have been anonymously included on the registry. The following 7 countries participated in the register: Russian Federation, Republic of Armenia, Republic of Belarus, Republic of Kazakhstan, Kyrgyz Republic, Republic of Moldova, Republic of Uzbekistan. This closed multicenter register with two nonoverlapping branches (in- and outpatient branch) provides 6 visits: 3 in-person visits during the acute period and 3 telephone calls after 3, 6, 12 months. Subject recruitment lasted from June 29, 2020 to October 29, 2020. Register will end on October 29, 2022. A total of 9 fragmentary analyzes of the registry data are planned. This fragment of the study presents the results of the post-hospitalization period in COVID-19 survivors after 3 and 6 months. Results. According to the AKTIV register, patients after COVID-19 are characterized by long-term persistent symptoms and frequent seeking for unscheduled medical care, including rehospitalizations. The most common causes of unplanned medical care are uncontrolled hypertension (HTN) and chronic coronary artery disease (CAD) and/or decompensated type 2 diabetes (T2D). During 3- and 6-month follow-up after hospitalization, 5,6% and 6,4% of patients were diagnosed with other diseases, which were more often presented by HTN, T2D, and CAD. The mortality rate of patients in the post-hospitalization period was 1,9% in the first 3 months and 0,2% for 4-6 months. The highest mortality rate was observed in the first 3 months in the group of patients with class II-IV heart failure, as well as in patients with cardiovascular diseases and cancer. In the pattern of death causes in the post-hospitalization period, following cardiovascular causes prevailed (31,8%): acute coronary syndrome, stroke, acute heart failure. Conclusion. According to the AKTIV register, the health status of patients after COVID-19 in a serious challenge for healthcare system, which requires planning adequate health system capacity to provide care to patients with COVID-19 in both acute and post-hospitalization period

Prospect and potential of Burkholderia sp. against Phytophthora capsici Leonian: a causative agent for foot rot disease of black pepper

Foot rot disease is a very destructive disease in black pepper in Malaysia. It is caused by Phytophthora capsici Leonian, which is a soilborne pathogenic protist (phylum, Oomycota) that infects aerial and subterranean structures of many host plants. This pathogen is a polycyclic, such that multiple cycles of infection and inoculum production occur in a single growing season. It is more prevalent in the tropics because of the favourable environmental conditions. The utilization of plant growth-promoting rhizobacteria (PGPR) as a biological control agent has been successfully implemented in controlling many plant pathogens. Many studies on the exploration of beneficial organisms have been carried out such as Pseudomonas fluorescens, which is one of the best examples used for the control of Fusarium wilt in tomato. Similarly, P. fluorescens is found to be an effective biocontrol agent against the foot rot disease in black pepper. Nowadays there is tremendous novel increase in the species of Burkholderia with either mutualistic or antagonistic interactions in the environment. Burkholderia sp. is an indigenous PGPR capable of producing a large number of commercially important hydrolytic enzymes and bioactive substances that promote plant growth and health; are eco-friendly, biodegradable and specific in their actions; and have a broad spectrum of antimicrobial activity in keeping down the population of phytopathogens, thus playing a great role in promoting sustainable agriculture today. Hence, in this book chapter, the potential applications of Burkholderia sp. to control foot rot disease of black pepper in Malaysia, their control mechanisms, plant growth promotion, commercial potentials and the future prospects as indigenous PGPR were discussed in relation to sustainable agriculture

Effects of spironolactone and eplerenone on left ventricular diastolic function and neurohumoral factors in patients with heart failure

Aim. To study the effects  of spironolactone  and eplerenone on left ventricular diastolic function and neurohumoral factors in patients with heart failure (HF).Material and methods. We examined 131 patients  with coronary artery disease  and NYHA class  I-III HF. Patients  were randomized  into groups depending  on HF class: class I (n=31), class II (n=51) and class III (n=49).Results. The study revealed that the clinical course  of HF and LV diastolic dysfunction are associated with an increased  level of neurohormones  and are characterized by significantly high levels of aldosterone  and norepinephrine  in patients  with a restrictiveLV diastolic dysfunction. A correlation was found between  the level of neurohormones  (aldosterone  and norepinephrine)  and heart  remodeling parameters:  an inverse correlation with an ejection fraction (r=-0,68, r=-0,61,  respectively) and a direct correlation with LV  end-diastolic volume (r=0,58, r=0,66, respectively). Long-term treatment  with spironolactone  and eplerenone had a positive effect, reducing the level of mentioned neurohormones. In patients with class II HF, both drugs had a positive effect on the level of aldosterone  and norepinephrine, reducing them by 26,6% and 20,2% in the spironolactone  group and by 28,4% and  24,6% in the eplerenone group,  respectively.  In patients with class  III  HF, the decrease in aldosterone  level was more pronounced  in those taking eplerenone than spironolactone:  32,1% vs 20,2%, respectively.Conclusion. In patients  with HF, combination therapy with the inclusion of spironolactone  significantly reduced  the level of neurohormones mainly in patients with class II HF and, to a lesser extent, in those with class III HF. This suggests that combination therapy with spironolactone is less effective than with eplerenone in relation to neurohormones’  levels

Socialization Of Youth In Modern Society

This article refers the reasoning about personality and its socialization, to focus on the factors that can make this process effective. Meanwhile, socialization presupposes a high degree of inner activity of the individual, the need for its self-realization. In other words, a lot depends on the person, his ability to manage his own activities
