Attachment, mentalizing, and eating disorder symptoms in adolescent psychiatric inpatients and healthy controls: a test of a mediational model.

OBJECTIVE: Research has supported a link between insecure attachment and eating disorders (EDs) in adolescents; however, mechanisms accounting for this association remain unclear. Growing evidence suggests impaired mentalizing as a potential mechanism. Yet, little is known about the relationship between mentalizing and ED symptoms or how it relates to the link between attachment and EDs in adolescents. This study examined mentalizing deficits in adolescents with ED symptoms relative to psychiatric and healthy controls and tested a mediational model, wherein mentalizing capacity mediates the relationship between attachment and ED symptoms. METHOD: Inpatient adolescents with EDs and other pathology (n = 568) and healthy controls (n = 184) were administered the child attachment interview, the movie for the assessment of social cognition and the diagnostic interview schedule for children to assess attachment, mentalizing and ED symptoms, respectively. RESULTS: Inpatients showed lower attachment security and more hypermentalizing than healthy adolescents. Hypermentalizing explained the association between insecure attachment and ED symptoms. CONCLUSIONS: These findings suggest potential utility of targeting mentalizing in prevention and treatment of EDs in adolescents. LEVEL OF EVIDENCE: Level III, case-control analytic study.

Comparison of endoscopic laser therapy and self expanding metal stents for palliation in patients with non-resectable oesophageal carcinoma.

BACKGROUND: There are currently limited data on the comparative success of endoscopic laser therapy (NLT) and self expanding metal stents (SEMS) as palliative measures in patients with non-resectable oesophageal cancer. This study aims to assess and compare the outcomes of these methods of endoscopic palliation. METHODS: Patients with non-curative oesophageal/gastro-oesophageal cancers with dysphagia were identified prospectively and consented to swallow assessment and follow-up. Patients underwent SEMS or NLT at the discretion of the treating endoscopist. Initial standardised swallow scores (0-4) were assessed. All subsequent interventions were recorded as well as survival. RESULTS: 31 patients were recruited (30M vs 8F, mean age 70.8). There was no significant difference in age, sex or chemotherapy treatment between groups. 19(61%)patients underwent NLT as primary procedure. 20(64.5%) patients required subsequent intervention(s) (median 1, range 0-8). Primary NLT patients were more likely to require subsequent therapy (p = 0.004) and multiple procedures (p = 0.001). 8(42.1%)patients initially undergoing NLT subsequently required SEMS, while no SEMS patients underwent subsequent NLT. Swallow scores of 1 or 2 were more likely to be maintained with NLT while scores of 3 or 4 were more likely to progress to SEMS (p = 0.039). Time to repeat procedure was greater in the SEMS group (p = 0.001). Median survival was 133 days for NLT vs 60 days for SEMS (p = 0.412). CONCLUSION: In this series, patients selected for NLT had a trend towards longer survival, but were more likely to require repeated procedures. Those with lower early initial dysphagia scores were more likely to be maintained by NLT alone.

Large-scale screening and characterization of enteroviruses and kobuviruses infecting pigs in Vietnam.

A recent survey of pigs in Dong Thap province, Vietnam identified a high frequency of enterovirus species G (EV-G) infection (144/198; 72.7%). Amongst these was a plethora of EV-G types (EV-G1, EV-G6 and four new types EV-G8-EV-G11). To better characterize the genetic diversity of EV-G and investigate the possible existence of further circulating types, we performed a larger-scale study on 484 pig and 45 farm-bred boar faecal samples collected in 2012 and 2014, respectively. All samples from the previous and current studies were also screened for kobuviruses. The overall EV infection frequency remained extremely high (395/484; 81.6%), but with comparable detection rates and viral loads between healthy and diarrhoeic pigs; this contrasted with less frequent detection of EV-G in boars (4/45; 8.9%). EV was most frequently detected in pigs ≤ 14 weeks old (∼ 95%) and declined in older pigs. Infections with EV-G1 and EV-G6 were most frequent, whilst less commonly detected types included EV-G3, EV-G4 and EV-G8-EV-G11, and five new types (EV-G12-EV-G16). In contrast, kobuvirus infection frequency was significantly higher in diarrhoeic pigs (40.9 versus 27.6%; P = 0.01). Kobuviruses also showed contrasting epizootiologies and age associations; a higher prevalence was found in boars (42%) compared with domestic pigs (29%), with the highest infection frequency amongst pigs >52 weeks old. Although genetically diverse, all kobuviruses identified belonged to the species Aichivirus C. In summary, this study confirms infection with EV-G was endemic in Vietnamese domestic pigs and exhibits high genetic diversity and extensive inter-type recombination.

Quantification of the effects of audible rattle and source type on the human response to environmental vibration.

The present research quantifies the influence of source type and the presence of audible vibration-induced rattle on annoyance caused by vibration in residential environments. The sources of vibration considered are railway and the construction of a light rail system. Data were measured in the United Kingdom using a socio-vibration survey (N = 1281). These data are analyzed using ordinal logit models to produce exposure-response relationships describing community annoyance as a function of vibration exposure. The influence of source type and the presence of audible vibration-induced rattle on annoyance are investigated using dummy variable analysis, and quantified using odds-ratios and community tolerance levels. It is concluded that the sample population is more likely to express higher levels of annoyance if the vibration source is construction compared to railway, and if vibration-induced rattle is audible.

Pharmacokinetics and preliminary safety data of a single oral dose of bosentan, a dual endothelin receptor antagonist, in cats.

The objective of this study was to evaluate the pharmacokinetic properties and adverse effect profile of single-dose oral bosentan, a dual endothelin receptor antagonist, in healthy cats. Pharmacokinetic parameters were determined following a single mean ± SD oral dose of 3.2 ± 0.6 mg/kg of bosentan in 6 adult cats. Blood was collected for quantification of bosentan via high-performance liquid chromatography with ultraviolet detection. Blood and urine were evaluated for CBC, plasma biochemical profile, and urinalysis, and repeat physical examinations were performed to evaluate for adverse effects. The mean terminal half-life of bosentan was 20.4 ± 17.2 h. The mean peak plasma concentration was 0.49 ± 0.24 g/mL, and the mean time to maximum plasma concentration was 6.8 ± 8.6 h. The area under the curve was 5.14 ± 3.81 h·µg/mL. Oral bosentan tablets were absorbed in cats, and no clinically important adverse events were noted. Further evaluation of repeat dosing, investigation into the in vivo efficacy of decreasing endothelin-1 concentrations in cats, as well as safety in conjunction with other medications is warranted.

The mobility of the brachycephalic canine nostril in relation to the degree of nostril stenosis.

Previous studies have shown that the most reliable external conformational risk factor of whether a brachycephalic dog will develop Brachycephalic Obstructive Airway Syndrome (BOAS) is the status of nostril stenosis, assessed as a static observation using the brachycephalic nostril grading scheme. The nostrils however are a dynamic structure, opening further when the dog is exercising, sniffing or panting. The hypothesis of this study was that brachycephalic dogs with open or mildly stenotic nostrils are more likely to have nostril mobility whilst dogs with moderately or severely stenotic nostrils are more likely to have immobile nostrils. A retrospective study of dogs presented for BOAS assessment at two UK referral centres between 2012 and 2020 was performed. Data extracted included nares stenosis status and nares mobility. A mesocephalic pilot control group was recruited from a third referral centre. Statistical analysis was performed with χ2, Cochran-Armitage, spearman's rho and linear-by-linear tests as appropriate. Of the 974 brachycephalic dogs included in the study: 124 had open nostrils (68.5% mobile); 212 mildly stenotic nostrils (58.5% mobile); 379 moderately stenotic nostrils (35% mobile) and 259 severely stenotic nostrils (19.3% mobile). The nostril stenotic status was significantly associated with nostril wing mobility (χ2 =135.55; P<0.0001). When considering open and mildly stenotic (considered acceptable) nostrils versus moderate and severely stenotic nostrils, mobility was 62% versus 25.5% (χ2= 135.88; P = <0.0001). All 27 mesocephalic dogs had nostril mobility. Brachycephalic dogs with moderate and severely stenotic nares have reduced nasal mobility compared to brachycephalic dogs with mildly stenotic and open nares. Data is further evidence that dogs with moderately and severely stenotic nares should not be bred.

Quantifying the Representation of Black Adolescents in Suicide Intervention Research.

This systematic review aimed to quantify the representation of Black youth in U.S. suicide intervention research. Specifically, we sought to evaluate Black youth representation in terms of (a) equity of inclusion (i.e., the inclusion of Black youth in research study samples at a rate consistent with the overall national rate of Black adolescents in the US) and (b) equity of intervention efficacy (i.e., evaluating the presence of racial disparities in intervention efficacy/effect sizes). In addition, we aimed to evaluate whether an association existed between funding status of research and representation of Black youth in studies, and to provide recommendations for future research in this area. To this end, the present study extracted and analyzed demographic information of studies included in recent meta-analyses conducted by Robinson and colleagues (2018), which were not previously analyzed, in addition to new literature published between September 2017 and January 2021. Results showed that the prevalence of Black youth included in studies was representative (14.67%; ntotal = 4451, nBlack = 664), with a median inclusion rate of 13%; however, absolute sample and group sizes were so small that it precluded comparison of differential treatment outcomes for Black youth. Thus, out of 22 studies identified, only one was able to investigate treatment outcomes for suicide in Black youth specifically. This study points to the conclusion that without adequately powered studies, disparities in treatment efficacy for Black youth cannot be compared or addressed, and the existing disparity in suicidal outcomes for Black youth will grow even larger.

Uncertainty quantification of the impact of peripheral arterial disease on abdominal aortic aneurysms in blood flow simulations.

Peripheral arterial disease (PAD) and abdominal aortic aneurysms (AAAs) often coexist and pose significant risks of mortality, yet their mutual interactions remain largely unexplored. Here, we introduce a fluid mechanics model designed to simulate the haemodynamic impact of PAD on AAA-associated risk factors. Our focus lies on quantifying the uncertainty inherent in controlling the flow rates within PAD-affected vessels and predicting AAA risk factors derived from wall shear stress. We perform a sensitivity analysis on nine critical model parameters through simulations of three-dimensional blood flow within a comprehensive arterial geometry. Our results show effective control of the flow rates using two-element Windkessel models, although specific outlets need attention. Quantities of interest like endothelial cell activation potential (ECAP) and relative residence time are instructive for identifying high-risk regions, with ECAP showing greater reliability and adaptability. Our analysis reveals that the uncertainty in the quantities of interest is 187% of that of the input parameters. Notably, parameters governing the amplitude and frequency of the inlet velocity exert the strongest influence on the risk factors' variability and warrant precise determination. This study forms the foundation for patient-specific simulations involving PAD and AAAs which should ultimately improve patient outcomes and reduce associated mortality rates.

A locus for bipolar affective disorder on chromosome 4p.

The main clinical feature of bipolar affective disorder is a change of mood to depression or elation. Unipolar disorder, also termed major depressive disorder, describes the occurrence of depression alone without episodes of elevated mood. Little is understood about the underlying causes of these common and severe illnesses which have estimated lifetime prevalences in the region of 0.8% for bipolar and 6% for unipolar disorder. Strong support for a genetic aetiology is found in the familial nature of the condition, the increased concordance of monozygotic over dizygotic twins and adoption studies showing increased rates of illness in children of affected parents. However, linkage studies have met with mixed success. An initial report of linkage on the short arm of chromosome 11 (ref. 4) was revised and remains unreplicated. Reports proposing cosegregation of genes found on the X chromosome with bipolar illness have not been supported by others. More recently bipolar disorder has been reported to be linked with markers on chromosomes 18, 21, 16 and a region on the X chromosome different from those previously suggested. We have carried out a linkage study in twelve bipolar families. In a single family a genome search employing 193 markers indicated linkage on chromosome 4p where the marker D4S394 generated a two-point lod score of 4.1 under a dominant model of inheritance. Three point analyses with neighbouring markers gave a maximum lod score of 4.8. Eleven other bipolar families were typed using D4S394 and in all families combined there was evidence of linkage with heterogeneity with a maximum two-point lod score of 4.1 (theta = 0, alpha = 0.35).

Scoping review report: obesity in older adults.

Obesity is associated with an increased risk for early death, heart disease and stroke, disability and several other comorbidities. Although there is concern about the potential burden on health-care services with the aging demographic and the increasing trend of obesity prevalence in older adults, evidence on which to base management strategies is conflicting for various reasons. The analytic framework for this review is based on a scoping review methodology, and was conducted to examine what is known about the diagnosis, treatment and management of obesity in older adults. A total of 492 relevant research articles were identified using PubMed, Scirus, EBSCO, Clinicaltrials.gov, Cochrane Reviews and Google Scholar. The findings of this review indicate that the current WHO (World Health Organization)-recommended body mass index, waist circumference and waist-to-hip ratio obesity thresholds for the general adult population may not be appropriate for older adults. Alternatively, weight change or physical fitness may be more useful measures of mortality and health risk in obese older adults. Furthermore, although obesity in older adults is associated with several disorders that increase functional disability, epidemiological evidence suggests that obesity is protective against mortality in seniors. Consequently, the trend toward increasing prevalence of obesity in older adults will lead to an increase in unhealthy life years and health-care costs. The findings from this review also suggest that treatment strategies for obese older adults should focus on maintaining body weight and improving physical fitness and function rather than weight loss, and that a combination of aerobic and resistance exercise appears to be the most effective strategy. In conclusion, this review demonstrates the need for more research to clarify the definition of obesity in older adults, to establish criteria for evaluating when to treat older adults for obesity, and to develop effective treatment strategies focused on functional outcomes in obese older adults.

Systematic review and meta-analysis of wound dressings in the prevention of surgical-site infections in surgical wounds healing by primary intention.

BACKGROUND: Postoperative surgical-site infections are a major source of morbidity and cost. This study aimed to identify and present all randomized controlled trial evidence evaluating the effects of dressings on surgical-site infection rates in surgical wounds healing by primary intention; the secondary outcomes included comparisons of pain, scar and acceptability between dressings. METHODS: Randomized controlled trials comparing alternative wound dressings, or wound dressings with leaving wounds exposed for postoperative management of surgical wounds were included in the review regardless of their language. Databases searched included the Cochrane Wounds Group Specialised Register and Central Register of Controlled Trials, Ovid MEDLINE, Ovid Embase and EBSCO CINAHL from inception to May 2011. Two authors performed study selection, risk of bias assessment and data extraction, including an assessment of surgical contamination according to the surgical procedure. Where levels of clinical and statistical heterogeneity permitted, data were pooled for meta-analysis. RESULTS: Sixteen controlled trials with 2594 participants examining a range of wound contamination levels were included. They were all unclear or at high risk of bias. There was no evidence that any dressing significantly reduced surgical-site infection rates compared with any other dressing or leaving the wound exposed. Furthermore, no significant differences in pain, scarring or acceptability were seen between the dressings. CONCLUSION: No difference in surgical-site infection rates was demonstrated between surgical wounds covered with different dressings and those left uncovered. No difference was seen in pain, scar or acceptability between dressings.

Health-related quality of life in patients with osteoporosis in the absence of vertebral fracture: a systematic review.

To review whether osteoporosis in the absence of vertebral fracture (VFX) affects health-related quality of life (HRQoL), a systematic search of the main literature databases for HRQoL in patients with osteoporosis without VFX was undertaken. This was undertaken. This identified 1,327 articles as potentially relevant to the review. After screening of abstracts and reviewing 168 articles in detail, 27 were considered relevant. HRQoL data were extracted and collated into tables and, where possible, were converted into normative scores and further analysed. Data relating to the associations between HRQoL and bone mineral density (BMD) were also collated. Of the 27 articles included, only 5 directly compared osteoporosis without VFX with a control group (BMD T-score > -1.0, without VFX). Extracted raw data from 21 articles demonstrated that patients with osteoporosis without VFX had clinically relevant reductions in role physical, general health, vitality, mental health domains and the mental component summary score, using SF36. Using Qualeffo-41, pain and physical function were worse in these patients. Also, HRQoL was related to upper femur, but not lumbar spine BMD. HRQoL data in patients with osteoporosis without VFX are limited and variable but suggest that HRQoL is adversely affected by osteoporosis in the absence of VFX. The association of lower BMD and worse HRQoL suggests that more attention should be paid to HRQoL in those without VFX. Future studies are needed to investigate HRQoL in patients with osteoporosis in the absence of fracture, controlling for co-morbidities and social and economic status.

COVID-19 conversations: A qualitative study of majority Hispanic/Latinx youth experiences during early stages of the pandemic.

Background: Growing evidence informs about the detrimental impact that COVID-19 has had on youths' mental health and well-being. As of yet, no study has directly examined the experiences and perspectives of children and young adolescents from racial and ethnic minority groups in the U.S., despite being exposed to more adversity, which may affect coping with the many challenges posed by the pandemic. Objective: This study aimed to give voice to a mostly Hispanic/Latinx group of youth regarding the impact of COVID-19 stay-at-home measures and to identify their emotional responses and coping strategies amid the pandemic in the U.S. when restrictions were at their hardest. Method: A total of 17 youths (70.6 % Hispanic; age range = 10-14 years; 52.9 % female) participated in four virtual semi-structured focus groups for each grade level (grades 5-8). Data was transcribed and analyzed using a gold standard thematic analysis approach. Results: Seven themes were identified concerning the impact of COVID-19, centering around the impact of racism, loss of income, the role of community and family in coping with stress, information overload, home-schooling, loneliness and boredom, and lack of structured routines. Conclusions: Our findings suggest that cultural factors (e.g., collectivism and familism) in Hispanic communities may offer important buffering during COVID-19. Future research studies evaluating the implementation of structured programs that provide a space to talk about emotions and thoughts related to the impact of the pandemic and training in strategies to cope with distress during mandatory home-schooling are needed.

Parametric analysis of an efficient boundary condition to control outlet flow rates in large arterial networks.

Substantial effort is being invested in the creation of a virtual human-a model which will improve our understanding of human physiology and diseases and assist clinicians in the design of personalised medical treatments. A central challenge of achieving blood flow simulations at full-human scale is the development of an efficient and accurate approach to imposing boundary conditions on many outlets. A previous study proposed an efficient method for implementing the two-element Windkessel model to control the flow rate ratios at outlets. Here we clarify the general role of the resistance and capacitance in this approach and conduct a parametric sweep to examine how to choose their values for complex geometries. We show that the error of the flow rate ratios decreases exponentially as the resistance increases. The errors fall below 4% in a simple five-outlets model and 7% in a human artery model comprising ten outlets. Moreover, the flow rate ratios converge faster and suffer from weaker fluctuations as the capacitance decreases. Our findings also establish constraints on the parameters controlling the numerical stability of the simulations. The findings from this work are directly applicable to larger and more complex vascular domains encountered at full-human scale.

The relation between measures of explicit shame and borderline personality features in adolescent inpatients.

BACKGROUND: Shame is a highly negative emotion frequently experienced by individuals with borderline personality disorder (BPD) as well as those with internalizing or externalizing psychopathology. However, few studies have examined whether shame is related to BPD above and beyond other psychopathology. Further, although feelings of shame peak during adolescence, coinciding with the onset of BPD, very few studies have examined the relationship between shame and BPD in adolescence. Therefore, the current study examined (1) whether levels of shame differ between adolescent psychiatric inpatients with and without BPD and (2) whether borderline personality pathology accounts for additional variance in the experience of shame above and beyond internalizing and externalizing psychopathology. METHODS: Adolescent psychiatric inpatients (n = 184, 67% female, M age = 15.26) completed clinical interviews and self-report measures as well as self-report measures of three types of explicit shame: state-shame, shame-proneness, and trait-shame. RESULTS: T-tests revealed that adolescents with BPD reported significantly higher levels of each type of explicit shame. In hierarchical regression models, borderline personality features explained significant additional variance in shame-proneness and trait-shame while controlling for age, gender, and internalizing and externalizing psychopathology. LIMITATIONS: Our sample was limited by a lack of demographic diversity and healthy control group, and the study did not examine relations with unique internalizing/externalizing disorders or features of BPD. CONCLUSIONS: Our findings contribute to growing evidence that shame is an important component of BPD, particularly during adolescence, and suggest that shame should be addressed in treatment.

Transfusion practice in Australia: an internet-based survey.

OBJECTIVE: To describe small animal transfusion practices in Australia, including access to blood products and frequency of pre-transfusion compatibility testing and medication administration. METHODS: An online survey was disseminated to target Australian veterinarians treating dogs and cats. Information collected included demographics, sources of blood products, blood storage, recipient compatibility testing and administration of medications pre-transfusion. Associations between the use of compatibility tests and premedications were assessed using the χ2 test. Significance was set at P < 0.05. RESULTS: A total of 199 Australian veterinarians were included; however, there was some attrition of respondents over the course of the survey. The majority of respondents were in general practice (n = 133/199). Access to fresh whole blood was commonly reported for dogs (n = 179/199) and cats (n = 131/198), whereas blood components were less commonly available (canine red blood cells [RBC], n = 52/199 and plasma, n = 157/199; feline RBC, n = 9/198 and plasma, n = 21/198). Most blood was sourced from the pets of owners affiliated with the veterinary clinic (n = 179/196). The respondents who did not blood type or crossmatch dogs were significantly more likely to use premedication than those who did these tests (both comparisons: P < 0.001). Likewise, the respondents who did not blood-type cats were significantly more likely to use premedication (P = 0.003); however, there was no association between crossmatching and using premedication in cats (P = 0.183). CONCLUSION: This is the first survey to describe transfusion practices across a variety of practice types throughout Australia. Future work is needed to determine how representative these results are of current transfusion practices across Australia, and if so, what can be done to optimise them.

A survey of enteric organisms detected by real-time PCR assay in faeces of dogs in Western Australia.

This retrospective observational study reports the enteric organisms detected in dogs in Western Australia that had a faecal PCR (fPCR) submitted to a commercial veterinary laboratory. Of 2025 fPCR results, Clostridium perfringens alpha toxin gene was most frequently detected (87.2%), followed by Campylobacter spp. (37.8%), canine parvovirus (10.5%), Giardia spp. (9.7%), Salmonella spp. (7.0%), canine enteric coronavirus (2.3%), and canine distemper virus (0.3%). C.perfringens alpha toxin gene and Campylobacter spp. were the most common organisms co-detected. There was no statistically significant seasonal variation. Further studies are required to elucidate the role these organisms play in gastrointestinal disease in dogs.

Intramyocardial haematoma causing right ventricular outflow obstruction after brown snake (Pseudonaja species) envenomation in a dog.

A 15-month-old, male neutered Staffordshire Bull Terrier cross was presented to its referring veterinarian collapsed and agonal. He was immediately intubated, manually ventilated, and treatment commenced for presumptive snake envenomation with two vials of Tiger/Multi-Brown Snake Antivenom (minimum 7000 units/vial). The dog was transferred to a referral hospital intubated. Additional diagnostics performed following arrival at the referral hospital included a urine snake venom detection kit test, which was positive for brown snake immunotype. Three additional vials of Tiger/Multi-Brown Snake Antivenom (minimum 7000 units/vial) were administered until the dog was extubated and able to stand. Venom-induced consumptive coagulopathy (VICC) was diagnosed based on prolonged clotting times and scleral haemorrhage. Paroxysms of right ventricular outflow tract (RVOT) origin ventricular arrhythmias were treated with lignocaine and sotalol. Four days after presentation, a new-grade IV/VI systolic heart murmur was auscultated, prompting an echocardiogram. An anechoic and compartmentalised mass measuring 43 mm × 19 mm was visualized within the right ventricular wall at the RVOT, immediately adjacent to the pulmonic valve. The mass was causing a RVOT obstruction. Its appearance was suggestive of an intramyocardial haematoma, most likely secondary to VICC. The dog remained cardiovascularly stable, and treatment consisted of supportive care. Recheck echocardiograms at 2 and 7 weeks after discharge revealed progressive improvement of the intramyocardial mass and resolution of the associated heart murmur. Although intramyocardial haematomas are rare, it should be considered as a differential in dogs that develop a newly diagnosed heart murmur and/or cardiac arrhythmia following brown snake envenomation.

Faecal PCR panel results and clinical findings in Western Australian dogs with diarrhoea.

AIM: To describe faecal PCR (fPCR) results and clinical findings of dogs seen at a university teaching hospital for diarrhoea. DESIGN: Retrospective case series (April 2015 to July 2018). PROCEDURE: Data were collected from the hospital electronic medical records. Data extracted included signalment, history, clinical signs, treatment, fPCR panel results, other faecal diagnostic test results and antimicrobial use. RESULTS: One hundred and sixty-eight dogs with diarrhoea had a fPCR panel submitted. Most dogs (115, 68.5%) had diarrhoea of 3 days or less duration. Clostridium perfringens alpha toxin gene was most frequently detected (156, 92.9%) by fPCR, followed by Campylobacter spp. (55, 32.7%), canine parvovirus (CPV) (29, 17.3%), Salmonella spp. (14, 8.3%) and Giardia spp. (9, 5.4%). For the 45 dogs that had a negative point-of-care CPV test, 13 were CPV fPCR positive; some of which were adult dogs with current vaccination status. A total of 94/168 (56%) dogs received antimicrobials at some time during the treatment of diarrhoea. CONCLUSION: Faecal PCR panels can identify dogs with enteric organisms in their faeces that traditional faecal diagnostics may miss, thus contributing additional information to the diagnostic process. Nonetheless, fPCR results should be interpreted in light of the clinical findings, and particular consideration given to avoiding inappropriate use of antimicrobials. This study highlights that testing for C. perfringens alpha toxin gene is not likely to be diagnostically helpful, and that adult dogs with diarrhoea might be identified as CPV positive with PCR testing, despite a negative point-of-care CPV test result and a current vaccination status.

SnakeMap: four years of experience with a national small animal snake envenomation registry.

SnakeMap is a national cloud-based, veterinary snakebite registry. It was designed to prospectively collect data of the clinical circumstances and temporospatial information on cases of snake envenomation in dogs and cats. We herein introduce the project and summarise the data from the first 4 years of SnakeMap. The registry is a veterinary community-based online database allowing case entry from veterinary hospitals across Australia. Registry data comprise hospital characteristics, patient characteristics, envenoming snake type, treatment and outcome variables, including time and geolocation of the snake bite. We present summative information on select key variables from the SnakeMap registry (1 July 2015 to 30 June 2019). Twenty-eight hospitals from 6 states/territories entered 624 cases into the registry, including 419 dogs (67%) and 205 cats (33%). Bite time was available in 216 animals of which 90 (42%) were reported to be bitten in the 3 hours between 03:00 pm and 05:59 pm; median bite to presentation interval was 60 (interquartile range [IQR] 30, 211) minutes in dogs and 95 (IQR 41, 238) minutes in cats. Bites occurred in the owner's yard in 356 dogs (85%) and 53 cats (26%). A snake venom detection kit was used in 172 cases (28%) and antivenom was administered in 523 cases (85%). Most animals (n = 534, 88%) survived to discharge (median hospitalisation of 25 [IQR 16, 62] hours). SnakeMap effectively collects relevant clinical data from dogs and cats with presumed snake bite and provides locally specific information on the epidemiology of snake envenomation in small animals.
