RESUMO
The Lake Titicaca frog is endangered due to threats such as water pollution, introduced species, and overharversting for markets, where people consume them as frog juice. This study, conducted June to November 2012, aimed to determinate the bacteria microflora living on the skin of frogs confiscated from the La Parada market, Lima, Peru, and housed individually in the Laboratory of Wildlife at the Faculty of Veterinary Medicine and Zootechnic of the Universidad Peruana Cayetano Heredia in Lima, Peru. Samples collected with sterile swabs and cultured on blood, tryptic soy, and MacConkey agars were investigated using commercially available test kits, to investigate the commonly encountered bacterial and potentially zoonotic microorganisms associated with their consumption. We found three species of zoonotic concern in the genus Vibro: Vibrio alginolyticus, Vibro cholerae, and Vibro fluvialis. Other Gram-negative species cultured included two different colonies of Aeromonas hydrophila, or Aeromonas caviae or Aeromonas sobria; Pseudomona luteola; one example of Weeksella virosa or Empedobacter brevis; and Citrobacter freundii. Gram-positive bacteria detected were Staphylococcus spp., Micrococcus spp., and Erysipelothrix rhusiopathiae. We recommend against the consumption of this frog due to the pathogens it may carry that could cause serious illness among consumers and in vendors who handle animals.

The British Paediatric Surveillance Unit (BPSU) conducts surveillance of rare paediatric conditions using active, or prospective, case finding. The reliability of estimates of incidence, which is the primary outcome of public health importance, depends on ascertainment being as near complete as possible. This paper reviews evidence of the completeness of ascertainment in recent surveillance studies run through the BPSU. Ascertainment varied between 49% and 94% depending on the study. These are upper estimates. This was the basis of a discussion on barriers and facilitators of ascertainment which we have separated into factors related to the condition, factors related to the study methods, factors related to the study team and factors related to the surveillance system infrastructure. This leads to a series of recommendations to ensure continuing high levels of ascertainment in active surveillance studies.

Lead (Pb) toxicity caused by the ingestion of Pb ammunition fragments in carcasses and offal is a threat to scavenging birds across the globe. African vultures are in critical decline, but research on whether Pb exposure is contributing to declines is lacking. In Africa, recreational hunting represents an important economic activity; however, Pb in leftover hunted carcasses and gut piles represents a dangerous food source for vultures. It is therefore important to establish whether recreational hunting is associated with Pb exposure in African vultures. We explored this issue for the critically endangered white-backed vulture (Gyps africanus) in Botswana by examining their blood Pb levels inside and outside of the hunting season, and inside and outside of private hunting areas. From 566 birds captured and tested, 30.2% birds showed elevated Pb levels (10 to <45⯵g/dl) and 2.3% showed subclinical exposure (≥45⯵g/dl). Higher blood Pb levels were associated with samples taken inside of the hunting season and from within hunting areas. Additionally, there was a significant interaction between hunting season and areas, with Pb levels declining more steeply between hunting and non-hunting seasons within hunting areas than outside them. Thus, all our results were consistent with the suggestion that elevated Pb levels in this critically endangered African vulture are associated with recreational hunting. Pb is known to be highly toxic to scavenging birds and we recommend that Pb ammunition in Botswana is phased out as soon as possible to help protect this rapidly declining group of birds.

BACKGROUND: Many developed countries have high mortality rates for fire-related deaths in children aged 0-14 years with steep social gradients. Evidence-based interventions to promote fire safety practices exist, but the impact of implementing a range of these interventions in children's services has not been assessed. We developed an Injury Prevention Briefing (IPB), which brought together evidence about effective fire safety interventions and good practice in delivering interventions; plus training and facilitation to support its use and evaluated its implementation. METHODS: We conducted a cluster randomised controlled trial, with integrated qualitative and cost-effectiveness nested studies, across four study sites in England involving children's centres in disadvantaged areas; participants were staff and families attending those centres. Centres were stratified by study site and randomised within strata to one of three arms: IPB plus facilitation (IPB+), IPB only, usual care. IPB+ centres received initial training and facilitation at months 1, 3, and 8. Baseline data from children's centres were collected between August 2011 and January 2012 and follow-up data were collected between June 2012 and June 2013. Parent baseline data were collected between January 2012 and May 2012 and follow-up data between May 2013 and September 2013. Data comprised baseline and 12 month parent- and staff-completed questionnaires, facilitation contact data, activity logs and staff interviews. The primary outcome was whether families had a plan for escaping from a house fire. Treatment arms were compared using multilevel models to account for clustering by children's centre. RESULTS: 1112 parents at 36 children's centres participated. There was no significant effect of the intervention on families' possession of plans for escaping from a house fire (adjusted odds ratio (AOR) IPB only vs. usual care: 0.93, 95%CI 0.58, 1.49; AOR IPB+ vs. usual care 1.41, 95%CI 0.91, 2.20). However, significantly more families in the intervention arms reported more behaviours for escaping from house fires (AOR IPB only vs. usual care: 2.56, 95%CI 01.38, 4.76; AOR IPB+ vs. usual care 1.78, 95%CI 1.01, 3.15). CONCLUSION: Our study demonstrated that children's centres can deliver an injury prevention intervention to families in disadvantaged communities and achieve changes in home safety behaviours.

In arid regions of the developing world, pastoralists and livestock commonly inhabit protected areas, resulting in human-wildlife conflict. Conflict is inextricably linked to the ecological processes shaping relationships between pastoralists and native herbivores and carnivores. To elucidate relationships underpinning human-wildlife conflict, we synthesized 15 years of ecological and ethnographic data from Ikh Nart Nature Reserve in Mongolia's Gobi steppe. The density of argali (Ovis ammon), the world's largest wild sheep, at Ikh Nart was among the highest in Mongolia, yet livestock were >90% of ungulate biomass and dogs >90% of large-carnivore biomass. For argali, pastoral activities decreased food availability, increased mortality from dog predation, and potentially increased disease risk. Isotope analyses indicated that livestock accounted for >50% of the diet of the majority of gray wolves (Canis lupus) and up to 90% of diet in 25% of sampled wolves (n = 8). Livestock composed at least 96% of ungulate prey in the single wolf pack for which we collected species-specific prey data. Interviews with pastoralists indicated that wolves annually killed 1-4% of Ikh Nart's livestock, and pastoralists killed wolves in retribution. Pastoralists reduced wolf survival by killing them, but their livestock were an abundant food source for wolves. Consequently, wolf density appeared to be largely decoupled from argali density, and pastoralists had indirect effects on argali that could be negative if pastoralists increased wolf density (apparent competition) or positive if pastoralists decreased wolf predation (apparent facilitation). Ikh Nart's argali population was stable despite these threats, but livestock are increasingly dominant numerically and functionally relative to argali. To support both native wildlife and pastoral livelihoods, we suggest training dogs to not kill argali, community insurance against livestock losses to wolves, reintroducing key native prey species to hotspots of human-wolf conflict, and developing incentives for pastoralists to reduce livestock density.

INTRODUCTION: Childhood poisonings are common, placing a substantial burden on health services. Case-control studies have found inconsistent evidence about modifiable risk factors for poisonings among children aged 0-4â years. This study quantifies associations between poison prevention practices and medically attended poisonings in children aged 0-4â years. METHODS: Multicentre case-control study conducted at hospitals, minor injury units and family practices from four study centres in England between 2010 and 2013. Participants comprised 567 children presenting with unintentional poisoning occurring at home and 2320 community control participants matched on age, sex, date of event and study centre. Parents/caregivers provided data on safety practices, safety equipment use, home hazards and potential confounders by means of self-completion questionnaires. Data were analysed using conditional logistic regression. RESULTS: Compared with community controls, parents of poisoned children were significantly more likely not to store medicines out of reach (adjusted OR (AOR) 1.59; 95% CI 1.21 to 2.09; population attributable fraction (PAF) 15%), not to store medicines safely (locked or out of reach (AOR 1.83; 95% CI 1.38 to 2.42; PAF 16%) and not to have put all medicines (AOR 2.11; 95% CI 1.54 to 2.90; PAF 20%) or household products (AOR 1.79, 95% CI 1.29 to 2.48; PAF 11%) away immediately after use. CONCLUSIONS: Not storing medicines out of reach or locked away and not putting medicines and household products away immediately after use increased the odds of secondary care attended poisonings in children aged 0-4â years. If associations are causal, implementing these poison prevention practices could each prevent between 11% and 20% of poisonings.

The Lake Titicaca frog (Telmatobius culeus) is critically endangered, primarily from overexploitation. However, additional threats, such as chytrid fungus ( Batrachochytrium dendrobatidis ), are poorly studied. We found moderate levels of chytrid infection using quantitative PCR. Our results enhance our understanding of chytrid tolerance to high pH and low water temperature.

The Peruvian Andes are the home of 27 species of frogs of the genus Telmatobius, many of which are critically endangered. Illegal trade of adult frogs for purported medical properties likely represents the major threat facing these species. This activity, besides reducing their populations, may contribute to the dissemination of the fungus Batrachochytrium dendrobatidis (Bd), which causes chytridiomycosis, a disease posing a threat to many populations of amphibians. We screened frogs confiscated by the Administration of Forestry and Wildlife in Lima, Peru, for Bd. We used real-time PCR to diagnose Bd at the Laboratory of Wildlife, Faculty of Veterinary Medicine and Zootecnics, Universidad Peruana Cayetano Heredia, in Lima and Pisces Molecular Laboratory in Boulder, Colorado, US. Of 62 samples collected during this study, 60% (37) were PCR positive for Bd, confirming that illegal trade of amphibians can pose a risk for disseminating Bd.

Apex predators can impact smaller predators via lethal effects that occur through direct killing, and non-lethal effects that arise when fear-induced behavioural and physiological changes reduce the fitness of smaller predators. A general outcome of asymmetrical competition between co-existing predator species is that larger predators tend to suppress the abundances of smaller predators. Here, we investigate interference effects that an apex predator, the dingo (Canis dingo), has on the acquisition of food and water by the smaller red fox (Vulpes vulpes), by exposing free-ranging foxes to the odour of dingoes and conspecifics in an arid environment. Using giving-up densities we show that foxes foraged more apprehensively at predator-odour treatments than unscented controls, but their food intake did not differ between dingo- and fox-odour treatments. Using video analysis of fox behaviour at experimental water stations we show that foxes spent more time engaged in exploration behaviour at stations scented with fox odour and spent more time drinking at water stations scented with dingo odour. Our results provide support for the idea that dingo odour exerts a stronger interference effect on foxes than conspecific odour, but suggest that the odours of both larger dingoes and unfamiliar conspecifics curtailed foxes' acquisition of food resources.

IMPORTANCE: Falls from furniture are common in young children but there is little evidence on protective factors for these falls. OBJECTIVE: To estimate associations for risk and protective factors for falls from furniture in children aged 0 to 4 years. DESIGN, SETTING, AND PARTICIPANTS: Multicenter case-control study at hospitals, minor injury units, and general practices in and around 4 UK study centers. Recruitment commenced June 14, 2010, and ended April 27, 2012. Participants included 672 children with falls from furniture and 2648 control participants matched on age, sex, calendar time, and study center. Thirty-five percent of cases and 33% of control individuals agreed to participate. The mean age was 1.74 years for cases and 1.91 years for control participants. Fifty-four percent of cases and 56% of control participants were male. Exposures included safety practices, safety equipment use, and home hazards. MAIN OUTCOMES AND MEASURES: Falls from furniture occurring at the child's home resulting in attendance at an emergency department, minor injury unit, or hospital admission. RESULTS: Compared with parents of control participants, parents of cases were significantly more likely not to use safety gates in the home (adjusted odds ratio [AOR], 1.65; 95% CI, 1.29-2.12) and not to have taught their children rules about climbing on kitchen objects (AOR, 1.58; 95% CI, 1.16-2.15). Cases aged 0 to 12 months were significantly more likely to have been left on raised surfaces (AOR, 5.62; 95% CI, 3.62-8.72), had their diapers changed on raised surfaces (AOR, 1.89; 95% CI, 1.24-2.88), and been put in car/bouncing seats on raised surfaces (AOR, 2.05; 95% CI, 1.29-3.27). Cases 3 years and older were significantly more likely to have played or climbed on furniture (AOR, 9.25; 95% CI, 1.22-70.07). Cases were significantly less likely to have played or climbed on garden furniture (AOR, 0.74; 95% CI, 0.56-0.97). CONCLUSIONS AND RELEVANCE: If estimated associations are causal, some falls from furniture may be prevented by incorporating advice into child health contacts, personal child health records, and home safety assessments about use of safety gates; not leaving children, changing diapers, or putting children in car/bouncing seats on raised surfaces; allowing children to play or climb on furniture; and teaching children safety rules about climbing on objects.

BACKGROUND: Sexually transmitted infections in children ought to raise concerns about sexual abuse. It is not known how frequently they are identified in the UK and Ireland, nor how well they are investigated. AIMS: To measure the incidence, mode of presentation, investigations and child protection procedures among children under 13 years and over 12 months of age presenting with infections of Neisseria gonorrhoea, Treponema pallidum, Chlamydia trachomatis or Trichomonas vaginalis in the UK and Republic of Ireland. METHODS: National surveillance study over 25 months through the British Paediatric Surveillance Unit. All consultant paediatricians in the UK and Republic of Ireland reported laboratory confirmed infections followed by a confidential questionnaire covering clinical details, investigation results and child protection outcomes. RESULTS: Fifteen cases were reported, giving an overall incidence of these infections of 0.075 cases per 100,000 children per year. Most were identified because they presented with symptoms. Five cases presented with ophthalmic infection. Laboratory investigation and screening for other infections was adequate in most cases. Although only three cases of sexual abuse were confirmed in court or case conference, abuse was suspected in a further seven cases based on clinical factors, family or social history. CONCLUSIONS: Sexually transmitted infections in children, although rare, are generally well investigated. The findings support current guidance on the management of sexually transmitted infection in young children and the need to maintain a high index of suspicion for sexual abuse. Isolated ophthalmic infection with N gonorrhoeae and C trachomatis occurs beyond infancy, but the mode of transmission is unclear.

BACKGROUND: Childhood unintentional and suspected poisonings are a serious public health problem. Evidence from systematic reviews demonstrates that home safety education in combination with safety equipment provision increases the safe storage of medicines and other products. There is lack of evidence that poisoning prevention practices reduce poisoning rates. OBJECTIVES: To estimate ORs for medically attended poisonings in children aged 0-4â years for items of safety equipment, home hazards and parental safety practices aimed at preventing poisoning, and to explore differential effects by child and family factors. DESIGN: Multicentre case-control study in UK hospitals with validation of parent-reported exposures using home observations. Cases are aged 0-4â years with a medically attended poisoning occurring at home, matched on age and sex with community controls. Children attending hospital for other types of injury will serve as unmatched hospital controls. Matched analyses will use conditional logistic regression; unmatched analyses will use unconditional logistic regression to adjust for confounding variables. The study requires 266 poisoning cases and 1064 matched controls to detect an OR of 0.64 for safe storage of medicinal products and of 0.65 for non-medicinal products, with 80% power, a 5% significance level and a correlation between exposures in cases and controls of 0.1. MAIN OUTCOME MEASURES: Unintentional childhood poisoning. DISCUSSION: This will be the largest study to date exploring modifiable risk factors for poisoning in young children. Findings will inform: policy makers developing poison prevention strategies, practitioners delivering poison prevention interventions, parents to reduce the risk of poisoning in their homes.

Wild Bactrian camels (Camela ferus) are listed as Critically Endangered by the International Union for Conservation of Nature (IUCN) and only persist in some of the most remote locations in northern China and southern Mongolia. Although the species has been recognized as an umbrella species for the fragile central Asian desert ecosystem and has been high on the conservation agenda, little is known about the species' habitat requirements, with most information coming from anecdotal sightings and descriptive studies. We compiled the only available telemetry data from wild camels worldwide. Seven wild camels, which were followed for 11-378 monitoring days, covered a total range of 28,410 km2, with individual annual ranges being >12,000 km2 for three animals followed over a year. Camels reacted strongly to capture events, moving up to 64 km from the capture site within a day, whereas normal average daily straight line distances were 3.0-6.4 km/day. Camels showed a preference for intermediate productivity values (NDVI, habitat type) and landscape parameters (distance to water, elevation) and an avoidance of steep slopes. Our telemetry results suggest that wild camels still range throughout the entire Great Gobi A Strictly Protected Area (SPA), are highly mobile, and very sensitive to human disturbance. Their habitat preference may be a trade-off between dietary and safety requirements. Small sample size did not allow the development of a full habitat model testing all variables simultaneously and we urgently call for more data from additional wild camels as a foundation for evidence driven conservation actions.
RESUMO
BACKGROUND: The UK has one of the highest fatality rates for deaths from fire-related injuries in children aged 0-14 years; these injuries have the steepest social gradient of all injuries in the UK. Children's centres provide children under five years old and their families with a range of services and information, including home safety, but their effectiveness in promoting injury prevention has yet to be evaluated. We developed a fire prevention intervention for use in children's centres comprising an Injury Prevention Briefing (IPB) which provides evidence on what works and best practice from those running injury prevention programmes, and a facilitation package to support implementation of the IPB. This protocol describes the design and methods of a trial evaluating the effectiveness and cost-effectiveness of the IPB and facilitation package in promoting fire prevention. METHODS/DESIGN: Pragmatic, multicentre cluster randomised controlled trial, with a nested qualitative study, in four study centres in England. Children's centres in the most disadvantaged areas will be eligible to participate and will be randomised to one of three treatment arms comprising: IPB with facilitation package; IPB with no facilitation package; usual care (control). The primary outcome measure will be the proportion of families who have a fire escape plan at follow-up. Eleven children's centres per arm are required to detect an absolute difference in the percentage of families with a fire escape plan of 20% in either of the two intervention arms compared with the control arm, with 80% power and a 5% significance level (2-sided), an intraclass correlation coefficient of 0.05 and assuming outcomes are assessed on 20 families per children's centre. Secondary outcomes include the assessment of the cost-effectiveness of the intervention, other fire safety behaviours and factors associated with degree of implementation of the IPB. DISCUSSION: This will be the first trial to develop and evaluate a fire prevention intervention for use in children's centres in the UK. Its findings will be generalisable to children's centres in the most disadvantaged areas of the UK and may also be generalisable to similar interventions to prevent other types of injury. TRIAL REGISTRATION: http://NCT01452191 (date of registration: 13/10/2011).

Conservation biology is a relatively new (began in the 1980s), value-based discipline predicated on the belief that biological diversity-from genes to populations to species to communities to ecosystems-is good and extinction is bad. Conservation biology grew from the recognition that the Earth has entered its sixth great extinction event, one that differs from previous great extinctions in that a single species-Homo sapiens-has caused this biodiversity crisis. A diverse, interacting set of variables drive current extinctions. As such, to succeed, conservation efforts usually require broad-based, interdisciplinary approaches. Conservationists increasingly recognize the importance of contributions by veterinary science, among many other disciplines, to collaborative efforts aimed at stemming the loss of biodiversity. We argue that, to improve success rates, many wildlife conservation programs must incorporate veterinarians as part of an interdisciplinary team to assess and address problems. Ideally, veterinarians who participate in conservation would receive specialized training and be willing to work as partners as part of a larger team of experts who effectively integrate their work rather than work independently (i.e., work as interdisciplinary, as opposed to multidisciplinary, teams, respectively). In our opinion, the most successful and productive projects involve interdisciplinary teams involving both biological and nonbiological specialists. Some researchers hold multiple degrees in biology and veterinary medicine or the biological and social sciences. These experts can often offer unique insight. We see at least 3 major areas in which veterinarians can immediately offer great assistance to conservation efforts: (1) participation in wildlife capture and immobilization, (2) leadership or assistance in addressing wildlife health issues, and (3) leadership or assistance in addressing wildlife disease issues, including using wildlife as sentinels to identify new and emerging diseases or epidemics of old diseases. We cover each of these main topics in detail.
