- Abstract
© 2019, The Author(s). Study design: Randomised double-blind factorial-design placebo-controlled trial. Objective: Urinary tract infections (UTIs) are common in people with spinal cord injury (SCI). UTIs are increasingly difficult to treat due to emergence of multi-resistant organisms. Probiotics are efficacious in preventing UTIs in post-menopausal women. We aimed to determine whether probiotic therapy with Lactobacillus reuteri RC-14+Lactobacillus GR-1 (RC14-GR1) and/or Lactobacillus rhamnosus GG+Bifidobacterium BB-12 (LGG-BB12) are effective in preventing UTI in people with SCI. Setting: Spinal units in New South Wales, Australia with their rural affiliations. Methods: We recruited 207 eligible participants with SCI and stable neurogenic bladder management. They were randomised to one of four arms: RC14-GR1+LGG-BB12, RC14-GR1+placebo, LGG-BB12+ placebo or double placebos for 6 months. Randomisation was stratified by bladder management type and inpatient or outpatient status. The primary outcome was time to occurrence of symptomatic UTI. Results: Analysis was based on intention to treat. Participants randomised to RC14-GR1 had a similar risk of UTI as those not on RC14-GR1 (HR 0.67; 95% CI: 0.39–1.18; P = 0.17) after allowing for pre-specified covariates. Participants randomised to LGG-BB12 also had a similar risk of UTI as those not on LGG-BB12 (HR 1.29; 95% CI: 0.74–2.25; P = 0.37). Multivariable post hoc survival analysis for RC14-GR1 only vs. the other three groups showed a potential protective effect (HR 0.46; 95% CI: 0.21–0.99; P = 0.03), but this result would need to be confirmed before clinical application. Conclusion: In this RCT, there was no effect of RC14-GR1 or LGG-BB12 in preventing UTI in people with SCI.

Wildlife Rescue and Rehabilitation Center ,Campylobacter spp ,Diurnal and nocturnal birds of prey ,Birds of prey - Abstract
A total of 170 birds of prey admitted to two Wildlife Rescue and Rehabilitation Centers of Italy were examined. Birds were subdivided in diurnal (n=15) and nocturnal (n=7) species, sampled by cloacal swabs and examined for Campylobacter spp. by cultural and molecular methods. Campylobacter spp. was isolated in 43 out of the 170 (25.3%) birds of prey examined. Among these, 43/43 (100%) were identiied as C. jejuni and 10/43 (23.3%) were identiied as C. coli recovered from mixed infections. Diurnal birds of prey showed a signicantly higher prevalence value (P = 0.0006) for Campylobacter spp. than nocturnal birds of prey.

CRIUV ,Common swift ,Salmonella Infanti - Abstract
Forty common swifts (Apus apus), synanthropic birds living in an urban environment closely with humans and other animals, were hospitalized in the public veterinary hospital of the Regional Reference Center of Urban Veterinary Hygiene located in Naples, Campania Region, Italy. Each bird was sampled for bacteriological analyses. Out of 40 common swifts examined, eight were found positive for Salmonella enterica serovar Infantis although no sign of salmonellosis (e.g. diarrhoea) was shown. Our results suggest this avian species as a novel potential reservoir for one of most important Salmonella serovars.

Zoonotic bacteria ,Urban pigeon ,Geographical Information System - Abstract
This study reports the results of a survey aimed at investigating the spatial distribution of Campylobacter jejuni, Escherichia coli O157 and Salmonella spp. from urban pigeons (Columba livia) of the coastal area of the Campania region (southern Italy). A geographical information system (GIS) of the Campania region was constructed utilizing as datalayers the administrative boundaries (at provincial and municipal levels) of the coastal area of the region. As a result, this territory was divided in 60 municipalities, the centroid of each municipality was identified and among all those present into the GIS database municipalities involved by waste crisis (n = 23) and municipalities without waste crisis (n = 37) were identified. Thirty pigeons closest to the centroid in each municipality were trapped and sampled by cloacal swabs for a total of 1,800 pigeons. Samples were analyzed by cultural, PCR and serotyping methods in order to isolate and to identify Campylobacter spp., E. coli O157 and Salmonella spp. Data regarding waste crisis (presence/absence) were analysed by univariate (Pearson’s chi-square test for independence) statistical analysis, using each bacteria’s (C. jejuni , E. coli O157 and Salmonella spp.) status (positive/negative) as dependent variables. The results of the present study showed a prevalence of 48.3% (870/1800), 7.8% (141/1800), and 0.9% (16/1800) for C. jejuni, E. coli O157, and S. Typhimurium, respectively. Pigeons sampled in the municipalities with the waste emergency showed a prevalence of infection significantly higher than that seen in pigeons sampled in the municipalities without the waste emergency. These findings clearly showed that urban pigeons in the coastal area of the Campania region may constitute an environmental reservoir of pathogens representing thus a source of infection for other birds, livestock and humans.

The use of long-term catheterisation to manage insensate bladders, often associated with spinal cord injury (SCI), increases the risk of microbial colonisation and infection of the urinary tract. Urinary tract infection (UTI) is typically diagnosed and treated based on the culturing of organisms from the urine, although this approach overlooks low titer, slow growing and non-traditional pathogens. Here, we present an investigation of the urinary tract microbiome in catheterised SCI individuals, using T-RFLP and metagenomic sequencing of the microbial community. We monitored three neurogenic patients over a period of 12 months, who were part of a larger study investigating the efficacy of probiotics in controlling UTIs, to determine how their urinary tract microbial community composition changed over time and in relation to probiotic treatment regimens. Bacterial biofilms adherent to urinary catheters were examined as a proxy for bladder microbes. The microbial community composition of the urinary tract differed significantly between individuals. Probiotic therapy resulted in a significant change in the microbial community associated with the catheters. The community also changed as a consequence of UTI and this shift in community composition preceded the clinical diagnosis of infection. Changes in the microbiota due to probiotic treatment or infection were transient, resolving to microbial communities similar to their pre-treatment communities, suggesting that the native community was highly resilient. Based on these results, we propose that monitoring a patient’s microbial community can be used to track the health of chronically catheterized patients and thus, can be used as part of a health-status monitoring prog

- Abstract
© 2016 Lee et al. Background: Urinary tract infections [UTIs] are very common in people with Spinal Cord Injury [SCI]. UTIs are increasingly difficult and expensive to treat as the organisms that cause them become more antibiotic resistant. Among the SCI population, there is a high rate of multi-resistant organism [MRO] colonisation. Non-antibiotic prevention strategies are needed to prevent UTI without increasing resistance. Probiotics have been reported to be beneficial in preventing UTIs in post-menopausal women in several in vivo and in vitro studies. The main aim of this study is to determine whether probiotic therapy with combinations of Lactobacillus reuteri RC-14 + Lactobacillus rhamnosus GR-1 [RC14-GR1] and/or Lactobacillus rhamnosus GG + Bifidobacterium BB-12 [LGG-BB12] are effective in preventing UTI in people with SCI compared to placebo. Method: This is a multi-site randomised double-blind double-dummy placebo-controlled factorial design study conducted in New South Wales, Australia. All participants have a neurogenic bladder as a result of spinal injury. Recruitment started in April 2011. Participants are randomised to one of four arms, designed for factorial analysis of LGG-BB12 and/or RC14-GR1 v Placebo. This involves 24 weeks of daily oral treatment with RC14-GR1 + LGG-BB12, RC14-GR1 + placebo, LGG-BB12 + placebo or two placebo capsules. Randomisation is stratified by bladder management type and inpatient status. Participants are assessed at baseline, three months and six months for Short Form Health Survey [SF-36], microbiological swabs of rectum, nose and groin; urine culture and urinary catheters for subjects with indwelling catheters. A bowel questionnaire is administered at baseline and three months to assess effect of probiotics on bowel function. The primary outcome is time from randomisation to occurrence of symptomatic UTI. The secondary outcomes are change of MRO status and bowel function, quality of life and cost-effectiveness of probioti

PATHOGENIC bacteria ,BIRDS of prey ,BIRDS as carriers of disease ,DISEASE prevalence ,VETERINARY epidemiology - Abstract
The importance of wild birds as potential vectors of disease has received recent renewed empirical interest, especially regarding human health although information regarding the enteropathogenic bacteria in birds of prey continue to be scant. This study was performed with the aim to evaluate the occurrence of enteropathogenic bacteria (i.e. Campylobacter spp. Escherichia coli, Salmonella spp.) in birds of prey carcasses in Southern Italy. The results of the present study showed a prevalence of 33·1% (49/148) for Campylobacter spp. where all positive isolates (49/49) were identified as Campylobacter jejuni, and among these positive 12/49 were also identified as Campylobacter coli. Thus, 12/49 birds of prey showed mixed infections for both Campylobacter species. Differences in Campylobacter spp. prevalence between diurnal and nocturnal birds were statistically significant (P = 0·016). Escherichia coli showed a prevalence of 6·8% (10/148) and were serogrouped as O26 (n = 3), O55 (n = 2), O145 (n = 5). Salmonella spp. showed a prevalence of 6·8% (10/148) and were serotyped as S. Napoli (n = 4), Salmonella salamae (n = 3) and S. Typhimurium (n = 3). Although wildlife disease outbreaks have often been underreported in the broader context of global epidemiology, results of the present study suggest that birds of prey may serve as a reservoir of pathogens for livestock and human health, acting at the animal-human-ecosystem interface.

The study was aimed at evaluating the prevalence of enteropathogenic bacteria (i.e. Campylobacter spp., shigatoxin-producing Escherichia coli, Salmonella spp.) in common quail (Coturnix coturnix). To achieve this goal, 70 common quails were collected during the hunting season in the Campania region (southern Italy). From each bird, cloacal swab samples were collected and subjected to culture methods, polymerase chain reaction and serotyping. The results of the present study showed a prevalence of 21.4% and 5.7% for Campylobacter spp. and shigatoxin-producing E. coli, respectively. In contrast, no Salmonella spp. was isolated. These findings show that common quail, as migratory birds, may constitute an environmental carrier of these pathogens representing a source of infection for other birds, livestock and humans.

Aim: To estimate the prevalence of thermotolerant Campylobacter spp. in commercially reared partridges (Perdix perdix) in southern Italy. Methods and Results: Cloacal swabs of partridges (n = 240), equally distributed between male and female birds, from a game bird farm located in the Southern Italy were examined for the prevalence of thermotolerant Campylobacter spp. The samples were processed in order to detect thermotolerant Campylobacter spp. by culture methods. The positive samples were then confirmed by multiplex polymerase chain reaction. Thermotolerant Campylobacter spp. were isolated from 118 (49·2%) of the 240 cloacal swabs examined. As proved by PCR, 100% of the strains were identified as Campylobacter coli (118/118), and 15 (12·7%) out of the 118 positive samples were also positive for Campylobacter jejuni. In contrast, Campylobacter lari was not identified. Adult partridges showed a significantly higher prevalence (P

As no data are available on the prevalence of cytolethal distending toxin (cdt) genes carried by Campylobacter spp. in laying hens, this study was conducted with the aim to evaluate the prevalence of both Campylobacter spp. and cdt genes in 1680 laying hens from four different farms. The samples were analyzed by culture methods and by polymerase chain reaction. Campylobacter spp. were isolated from 1097/1680 cloacal swabs. Among the isolates, 913 were identified as Campylobacter jejuni whereas 345 were identified as Campylobacter coli. All isolates carried cdt genes. The results presented here confirm the very common occurrence of C. jejuni and C. coli in laying hens and underline that the cdt genes may also be frequently present in both C. jejuni and C. coli isolates from laying hens.

- Abstract
Adventure Therapy (AT) is a therapeutic intervention utilizing the natural environment and adventure activities as tools for psychotherapeutic interventions. It has been demonstrated to be appropriate for the intervention of patients with borderline personality disorder (BPD). This study aims to evaluate the response to AT treatment compared with the response to treatment as usual (TAU), based on cognitive behavioural therapy, in the short and long term, assessing clinical, psychosocial, and functional outcomes; quality of life; and physical health levels. This study extends the sample of and is a follow-up to a pilot study published in 2021, with a sample of 30 patients in the AT group and 10 in the control group. It does not allow us to affirm that AT provides better outcomes than TAU, as the positive effects observed immediately after therapy seem to be attenuated in the long term. Therefore, the effectiveness of long-term psychotherapy did not show differences between AT and TAU therapies in the treatment of BPD patients. However, the effects of intangibles observed during therapy by professionals and patients were not reflected in the measurements collected. Therefore, we believe it is necessary to increase the programme duration, complement treatment with a specific physical health programme, assess results with more specific instruments, and/or move towards a qualitative methodology to measure perceived changes in clinical improvement. New studies are needed to evaluate the results of the proposed changes.

- Abstract
Background: Urinary tract infections [UTIs] are very common in people with Spinal Cord Injury [SCI]. UTIs are increasingly difficult and expensive to treat as the organisms that cause them become more antibiotic resistant. Among the SCI population, there is a high rate of multi-resistant organism [MRO] colonisation. Non-antibiotic prevention strategies are needed to prevent UTI without increasing resistance. Probiotics have been reported to be beneficial in preventing UTIs in post-menopausal women in several in vivo and in vitro studies. The main aim of this study is to determine whether probiotic therapy with combinations of Lactobacillus reuteri RC-14 + Lactobacillus rhamnosus GR-1 [RC14-GR1] and/or Lactobacillus rhamnosus GG + Bifidobacterium BB-12 [LGG-BB12] are effective in preventing UTI in people with SCI compared to placebo., Method: This is a multi-site randomised double-blind double-dummy placebo-controlled factorial design study conducted in New South Wales, Australia. All participants have a neurogenic bladder as a result of spinal injury. Recruitment started in April 2011. Participants are randomised to one of four arms, designed for factorial analysis of LGG-BB12 and/or RC14-GR1 v Placebo. This involves 24 weeks of daily oral treatment with RC14-GR1 + LGG-BB12, RC14-GR1 + placebo, LGG-BB12 + placebo or two placebo capsules. Randomisation is stratified by bladder management type and inpatient status. Participants are assessed at baseline, three months and six months for Short Form Health Survey [SF-36], microbiological swabs of rectum, nose and groin; urine culture and urinary catheters for subjects with indwelling catheters. A bowel questionnaire is administered at baseline and three months to assess effect of probiotics on bowel function. The primary outcome is time from randomisation to occurrence of symptomatic UTI. The secondary outcomes are change of MRO status and bowel function, quality of life and cost-effectiveness of probiotics in persons with SCI. The primary outcome will be analysed using survival analysis of factorial groups, with Cox regression modelling to test the effect of each treatment while allowing for the other, assuming no interaction effect. Hazard ratios and Kaplan-Meier survival curves will be used to summarise results., Discussion: If these probiotics are shown to be effective in preventing UTI and MRO colonisation, they would be a very attractive alternative for UTI prophylaxis and for combating the increasing rate of antibiotic resistance after SCI., Trial Registration: Australian New Zealand Clinical Trials Registry [ ACTRN 12610000512022 ]. Date of registration: 21 June 2010.

- Abstract
The thermodynamic stability of onion-like carbon (OLC) nanostructures with respect to highly oriented pyrolytic graphite (HOPG) was determined in the interval 765-1030 K by the electromotive force (emf) measurements of solid electrolyte galvanic cell: (Low) Pt|Cr3C2,CrF2,OLC|CaF2s.c.|Cr3C2,CrF2,HOPG|Pt (High). The free energy change of transformation HOPG = OLC was found positive below 920.6 K crossing the zero value at this temperature. Its trend with temperature was well described by a 3rd degree polynomial. The unexpected too high values of [Formula: see text] jointly to the HR-TEM, STEM and EELS evidences that showed OLC completely embedded in rigid cages made of a Cr3C2/CrF2 matrix, suggested that carbon in the electrodes experienced different internal pressures. This was confirmed by the evaluation under constant volume of [dP/dT by the α/κ ratio for OLC (0.5 MPa K(-1)) and HOPG (8 Pa K(-1)) where α and κ are the isobaric thermal expansion and isothermal compressibility coefficients, respectively. The temperature dependency of the pressure was derived and utilized to calculate the enthalpy and entropy changes as function of temperature and pressure. The highest value of the internal pressure experienced by OLC was calculated to be about 7 GPa at the highest temperature. At 920.6 K, ΔrH and ΔrS values are 95.8 kJ mol(-1) and 104.1 JK(-1) mol(-1), respectively. The surface contributions to the energetic of the system were evaluated and they were found negligible compared with the bulk terms. As a consequence of the high internal pressure, the values of the enthalpy and entropy changes were mainly attributed to the formation of carbon defects in OLC considered as multishell fullerenes. The change of the carbon defect fraction is reported as a function of temperature.
