The Consequences of Choking in Sport: A Constructive or Destructive Experience?

Through an empirical phenomenological methodology, the study examined the short- and long-term consequences of choking in sport. Eleven intermediate golfers (10 male, 1 female; age 23–50 years, M = 34.6, SD = 8.9) with handicaps of 6–18 (M = 10.91, SD = 3.98) completed phenomenological interviews that explored the perceived psychological impact of their choking episode(s). While the reported short-term consequences were negative (i.e., collapse in performance standards, limited attention/emotional control, and negative affect), most participants thought the long-term impact of choking was constructive, for it encouraged adversity-related growth. However, a small number of golfers identified the long-term consequences as highly destructive, including a loss of self-confidence, withdrawal from the sport, and, in 1 case, lowered self-worth. The findings of the study extend the choking literature by informing strategies that can be used to encourage constructive, rather than destructive, consequences from any choking episode that athletes may experience

Carbapenemase-producing Enterobacteriaceae in hospital wastewater:a reservoir that may be unrelated to clinical isolates [star]

Summary Background: Carbapenemase-producing Enterobacteriaceae (CPE) are an emerging infection control problem in hospitals worldwide. Identifying carriers can help reduce potential spread and infections. Aim: To assess whether testing hospital wastewater for CPE can supplement patient based screening for infection prevention purposes in a hospital without a recognised endemic CPE problem. Methods: Wastewater collected from hospital pipework on 16 occasions during February-March 2014 was screened for CPE using chromID®CARBA agar and chromID®CPS agar with a 10 μg ertapenem disc and combination disc testing. MICs were determined using British Society for Antimicrobial Chemotherapy methodology and carbapenemase genes detected by PCR or wholegenome sequencing. Selected isolates were typed by PFGE. Findings: Suspected CPE were recovered from all 16 wastewater samples. Of 17 isolates sent to Antimicrobial Resistance and Healthcare Associated Infections Reference Unit, six (four Citrobacter freundii and two Enterobacter cloacae complex) were New Delhi metallo–beta-lactamase (NDM) producers and the remaining 11 (six Klebsiella oxytoca and five Enterobacter cloacae complex), Guiana-Extended-Spectrum-5 (GES-5) producers, the first to be described in Enterobacteriaceae in the UK. The four NDM-producing C. freundii, two NDM-producing E. cloacae complex and 4/5 GES-5-producing E. cloacae complex were each indistinguishable isolates of the same three strains, whereas the six GES-5-producing K. oxytoca overall shared 79% similarity. Conclusion: CPE are readily isolated from hospital wastewater using simple culture methods. There are either undetected carriers of CPE excreting into the wastewater, or these CPE represent colonisation of the pipework. Surveillance of hospital wastewater for CPE does not appear helpful for infection control purposes

Case-Control Study of Risk Factors for Sporadic Giardiasis and Parasite Assemblages in North West England

Giardia duodenalis is a major cause of infectious gastroenteritis worldwide, and it is diversified into eight genetic assemblages (A to H), which are distinguishable only by molecular typing. There is some evidence that the assemblages infecting humans (assemblages A and B) may have different transmission routes, but systematically acquired data, combining epidemiological and molecular findings, are required. We undertook a case-control study with Giardia genotyping in North West England, to determine general and parasite assemblage-specific risk factors. For people without a history of foreign travel, swimming in swimming pools and changing diapers were the most important risk factors for the disease. People infected with assemblage B reported a greater number of symptoms and higher frequencies of vomiting, abdominal pain, swollen stomach, and loss of appetite, compared with people infected with assemblage A. More importantly, keeping a dog was associated only with assemblage A infections, suggesting the presence of a potential zoonotic reservoir for this assemblage. This is the first case-control study to combine epidemiological data with Giardia genotyping, and it shows the importance of integrating these two levels of information for better understanding of the epidemiology of this pathogen

Everyday Wild: How do preserved natural areas in the City of Edmonton contribute to adult perceptions of health and well-being?

This study used participant photography and semi-structured interviews with 33 participants to explore the perceived health and well-being effects of natural area parks in the City of Edmonton, Alberta. Findings include that the proximity of the natural areas to residences was essential as it allowed visits to be frequent and spontaneous. Participants appreciated the areas for their wild and natural character and that they existed for the benefit of other species. While in these areas, participants felt away from the city and valued having this feeling while in the middle of the city. The sense of being away gave people space to think, connect with themselves, and return refreshed to their lives. The natural areas facilitated connections to self, companions (including dog companions), and other visitors. Many participants felt a deep intimacy with the natural areas over time and connections to birds, animals, and trees that live in them

Effect of particle size, coupling agent and DDGS additions on Paulownia wood polypropylene composites

Studies aimed at improving the tensile, flexural, impact, thermal, and physical characteristics of wood–plastic composites composed of Paulownia wood flour derived from 36-month-old trees blended with polypropylene were conducted. Composites of 25% and 40% w/w of Paulownia wood were produced by twin-screw compounding and injection molding. Composites containing 0–10% by weight of maleated polypropylene were evaluated and an optimum maleated polypropylene concentration determined, i.e., 5%. The particle size distribution of Paulownia wood filler is shown to have an effect on the tensile and flexural properties of the composites. Novel combination composites of dried distiller’s grain with solubles mixed with Paulownia wood (up to 40% w/w) were produced and their properties evaluated. Depending on the composite tested, soaking composites for 872 h alters mechanical properties and causes weight gain
