Traumatic brain injury (TBI) heavily impacts the body: it damages the brain tissue and the peripheral nervous system and shifts homeostasis in many types of tissue. An acute brain injury compromises the “brain–gut-microbiome axis”, a well-balanced network formed by the brain, gastrointestinal tract, and gut microbiome, which has a complex effect: damage to the brain alters the composition of the microbiome; the altered microbiome affects TBI severity, neuroplasticity, and metabolic pathways through various bacterial metabolites. We modeled TBI in rats. Using a bioinformatics approach, we sought to identify correlations between the gut microbiome composition, TBI severity, the rate of neurological function recovery, and blood metabolome. We found that the TBI caused changes in the abundance of 26 bacterial genera. The most dramatic change was observed in the abundance of Agathobacter species. The TBI also altered concentrations of several metabolites, specifically citrulline and tryptophan. We found no significant correlations between TBI severity and the pre-existing gut microbiota composition or blood metabolites. However, we discovered some differences between the two groups of subjects that showed high and low rates of neurological function recovery, respectively. The present study highlights the role of the brain–gut-microbiome axis in TBI.

An immature female worm, Dirofilaria immitis, was isolated from the scrotum of a 14-month-old child. This is the first identification of human dirofilariosis caused by D. immitis in a relatively Northern region (Moscow) of the Russian Federation. The parasite was diagnosed by means of morphological examination of the worm, confirmed by PCR assay. This case raises questions about the range of the D. immitis distribution among humans in Russia. To better understand the geographical distribution of dirofilarioses, detailed clinical and epidemiological information should be collected from human cases with appropriate laboratory confirmation.
Introduction. The work is devoted to evaluating the results of our own research of sanitary-microbiological monitoring of environmental objects in diversified treatment-and-prophylactic institutions of stationary type and of the analysis both of domestic and foreign data in order justify of the list of priority controlled sanitary-microbiological indices of air and surfaces to ensure the safety of hospital environment, medical organizations stationary type, regardless of their functional purpose. Material and methods. The survey was conducted in various premises in the medical-prophylactic institutions of stationary type for two years. Studies included determination of microbial contamination of the air environment, working surfaces, hands of personnel with the detection of bacteriological, virological, and mycological parameters, followed by macroscopic and microscopic identification of microorganisms and identification using automated systems with the method of time-of-flight matrix-assisted laser mass spectrometry platform MALDI-TOF, based on the study of the mass spectra of ribosomal proteins in the range of 1000-10000 Daltons and bioinformatic comparison of the obtained spectrum with database reference spectra and PCR. Results. As a result, the research of surface washings in the premises of a multidisciplinary clinic revealed microbial contamination with conditionally pathogenic gram-positive cocci, including S.aureus, gram-positive and gram-negative bacteria posing a serious epidemiological danger to patients in these wards regardless of the MOST profile and requires mandatory monitoring taking into account of the used disinfectants. Conclusion. Our own research and analysis of domestic and foreign literature showed that it is not enough to monitor the air in the MOST premises only in terms of total microbiological contamination. In the operating, procedural and dressing blocks, as well as in the wards, physiotherapeutic, diagnostic, laboratory rooms and auxiliary units, it is also necessary to take into account other sanitary and microbiological indices: total microbes count, gram-positive rods and cocci, including S.aureus, fungi, adeno-, entero-, astroviruses, coliphages.
<p>In Almaty, there are currently more than 500,000 vehicles registered and there is an average of another 200,000 vehicles that enter the city from outlying Almaty Oblasts during working hours. The road network of Almaty has not grown since 1990 when the municipality estimated the number of cars in Almaty to be 100,000.</p><p>Almaty public transport system degrade and became ineffective with significant loss of safety and comfort level by the reason of privatization and occurring of “shadow” taxi at the service market. [1]</p>Almaty airport is not connected with railway stations Almaty 1, Almaty 2 and city center by a straight and comfortable public transport route. Thus, the prevailing number of airport visitors prefer travelling on personal transport or taxi. Which is, in turn, brings a negative environmental loads. In current circumstances, the Moscow Aeroexpress transport analogue may become a good solution for Almaty.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
