A microbiome study reveals the potential relationship between the bacterial diversity of a gymnastics hall and human health.

Currently, investigations on the microbiota of sports centers and related facilities have been carried out in some countries, which showed that Microsporum gypseum, Trichophyton mentagrophytes and T. tonsurans are important dermatoprotofungi. In China, some research on athletes and sports equipment between the fungal community and public health has made some interesting achievements. However, the bacterial group among them has not been reported. Therefore, The aim of this study was to uncover (I) gymnastic equipment is there potential pathogenic factors and (ii) is there any difference in the biomarker of bacterial in different types of gymnastic room? The samples were collected from the gymnastics halls of one university in western China and main sports equipment, including gymnastics carpets, moving barres, hoops and balls, as well as wall bars, parallel bars and horizontal bars. The 16S rDNA of all the samples was sequenced, and the analyses were performed using FaproTax, Bug base function prediction and Line Discriminant Analysis (LDA) Effect Size. A 16S rDNA sequence analysis revealed abundant bacterial species biodiversity on gymnasts and apparatuses from two gymnastics halls at a university in western China. An analysis using the FaproTax and Bugbase functional prediction platforms showed that there were some opportunistic pathogens on the athletes and equipment from the Rhythmic Gymnastics (RG) and Artistic Gymnastics (AG) halls, such as Staphylococcus and Corynebacteiaceae. Infectious agents associated with cancer induction and development, such as Ruminococcaceae, Veillonellaceae and Moraxellaceae, as well as microbial toxin producers with a potential impact on human health, were also detected. According to a line discriminant analysis (LDA effect size), the bacterial biomarker groups of the two gymnasiums were different at the phylum-genus level: for RG, Erysipelatoclostridium, Lachnospiraceae and Bacteroidales, while for AG, Rhizobiales. Based on the results of the investigation, we suggest that more comprehensive consideration should be given to indoor microbial biodiversity and related public health problems in school gymnasiums.

[Risk factors associated with systemic inflammatory response syndrome after flexible ueteroscopic lithotripsy based on enhanced recovery after surgery].

Objective: To investigate the risk factors of systemic inflammatory response syndrome (SIRS) in patients undergoing flexible ureteroscopic lithotripsy based on enhanced recovery after surgery (ERAS). Methods: The clinical data of 243 kidney stone cases who underwent flexible ureteroscopic lithotripsy based on ERAS in the First Affiliated Hospital of Wannan Medical College from January 2016 to December 2017 were analyzed retrospectively. The cases were divided into two groups according to whether they had SIRS after surgery: SIRS group (26 cases) and non-SIRS group (217 cases). The age, gender, laterality of kidney stone, history of previous kidney stone surgery, degree of hydronephrosis, multiple kidney stones, length of operation time, white blood cell count of preoperative urine routine, result of preoperative urine culture, use of preoperative antibiotics, diabetes and other chronic diseases in the groups were collected and analyzed. Results: SIRS occurred in 26 cases in this study, which accounted for 10.7% (26/243). Multivariate analysis found that, moderate and severe hydronephrosis (OR=6.711, P=0.008), stone burden ≥2 cm (OR=10.353, P<0.001), length of operation time ≥ 60 min (OR=5.583, P=0.011), white blood cell count of preoperative urine routine ≥25×10(6)/L (OR=6.195, P=0.005), positive preoperative urine culture (OR=4.216, P=0.011), diabetes and other chronic diseases (OR=4.532, P=0.006) were the independent risk factors for postoperative SIRS (P<0.05). Conclusions: The occurrence of SIRS after flexible ureteroscopic lithotripsy based on ERAS is closely correlated with hydronephrosis, stone burden, length of operation time, white blood cell count of preoperative urine routine, positive preoperative urine culture, diabetes and other chronic diseases.
