Rodenticide residues in non-target small mammal species and their occurrence in owl pellets

OBJECTIVES: Distinguishing the patterns of autoantibodies (AAB) against G-protein-coupled receptors in Chagas' cardiomyopathy and megacolon and the discovery of such a pattern in patients who are as yet asymptomatic could help to identify patients at high risk of developing the life-threatening complications of Chagas' disease. BACKGROUND: Such AAB against receptors as beta 1 (beta1-AAB), beta 2 (beta2-AAB), and muscarinergic 2 (M2-AAB) are thought to be involved in the pathogenesis of Chagas' cardiomyopathy and megacolon, the predominant manifestations of Chagas' disease, which is the most serious parasitic disease in Latin America. METHODS: Beta1-AAB, beta2-AAB, and M2-AAB were measured in the serum of asymptomatic Chagas' patients and in those with cardiomyopathy and/or megacolon. RESULTS: Nearly all Chagas' patients with cardiomyopathy and/or megacolon had AAB. Predominance of beta1-AAB combined with M2-AAB in Chagas' cardiomyopathy and beta2-AAB with M2-AAB in megacolon was found. Such patterns were also found in 34% of the asymptomatic patients, of whom 85% possessed a beta1-AAB level typical for Chagas' cardiomyopathy. CONCLUSIONS: The percentage of asymptomatic Chagas' patients who had a specific AAB pattern and had a beta1-AAB level above a defined cutoff point mirrors very well the epidemiological situation, which showed that clinical manifestations develop in nearly 30% of Chagas' patients and cardiomyopathy in nearly 90% of them. We hypothesize that beta1-, beta2-, and M2-AAB measurement might be a useful tool for risk assessment in the indeterminate state of Chagas' disease to select patients for earlier involvement in care programs. However, prospective studies are needed to further evaluate this hypothesis

Status of low-energy accelerator-based BNCT worldwide and in Argentina

Existing and active low-energy Accelerator-Based BNCT programs worldwide will be reviewed and compared. In particular, the program in Argentina will be discussed which consists of the development of an Electro-Static-Quadrupole (ESQ) Accelerator-Based treatment facility. The facility is conceived to operate with the deuteron-induced reactions 9Be(d,n)10B and 13C(d,n)14N at 1.45 MeV deuteron energy, as neutron sources. Neutron production target development status is specified. The present status of the construction of the new accelerator development laboratory and future BNCT centre is shown.Fil: Cartelli, Daniel Enrique.

Research to develop Spiritual Pedagogy, Awareness and Change

This is an Accepted Manuscript of an article published by Taylor & Francis in British Journal of Guidance and Counselling on 21-4-16, available online: http://dx.doi.org/10.1080/03069885.2016.1174976A co-operative inquiry group consisting of 8 counsellors met for 11 months to explore their experience of spirituality in their counselling training and in their work with clients (Swinton, 2010; 2015). The aim was to explore whether spirituality was absent from the process of counselling training, specifically to discover (1) how counsellors perceived and described their experience of spirituality in their training and (2) with a view to developing spiritual pedagogy; how spirituality could be incorporated into the training process of practitioner

Prevention of disease flares by risk-adapted stratification of therapy withdrawal in juvenile idiopathic arthritis : results from the PREVENT-JIA trial

Publisher Copyright: © Author(s) (or their employer(s)) 2022. Re-use permitted under CC BY-NC. No commercial re-use. See rights and permissions. Published by BMJ.OBJECTIVES: To investigate the ability of high-sensitivity C-reactive protein (hsCRP) and S100A12 to serve as predictive biomarkers of successful drug withdrawal in children with clinical remission of juvenile idiopathic arthritis (JIA). METHODS: This multicentre trial (PREVENT-JIA) enrolled 119 patients with JIA in clinical remission, and 100 patients reached the intervention phase in which the decision whether to continue or stop treatment was based on S100A12 and hsCRP levels. Patients were monitored for 12 months after stopping medication for flares of disease. Results were compared with withdrawal of therapy without biomarker-based stratification in patients from the German Biologika in der Kinderrheumatologie (BiKeR) pharmacovigilance registry. RESULTS: In the PREVENT-JIA group, 49 patients had a flare, and 45% of patients stopping medication showed flares within the following 12 months. All patients (n=8) continuing therapy due to permanently elevated S100A12/hsCRP at more than one visit flared during the observation phase. In the BiKeR control group, the total flare rate was 62%, with 60% flaring after stopping medication. The primary outcome, time from therapy withdrawal to first flare (cumulative flare rate after therapy withdrawal), showed a significant difference in favour of the PREVENT-JIA group (p=0.046; HR 0.62, 95% CI 0.38 to 0.99). As additional finding, patients in the PREVENT-JIA trial stopped therapy significantly earlier. CONCLUSION: Biomarker-guided strategies of therapy withdrawal are feasible in clinical practice. This study demonstrates that using predictive markers of subclinical inflammation is a promising tool in the decision-making process of therapy withdrawal, which translates into direct benefit for patients.

The timing of auditory sensory deficits in Norrie disease has implications for therapeutic intervention

Norrie disease is caused by mutation of the NDP gene, presenting as congenital blindness followed by later onset of hearing loss. Protecting patients from hearing loss is critical for maintaining their quality of life. This study aimed to understand the onset of pathology in cochlear structure and function. By investigating patients and juvenile Ndp-mutant mice, we elucidated the sequence of onset of physiological changes (in auditory brainstem responses, distortion product otoacoustic emissions, endocochlear potential, blood-labyrinth barrier integrity) and determined the cellular, histological, and ultrastructural events leading to hearing loss. We found that cochlear vascular pathology occurs earlier than previously reported and precedes sensorineural hearing loss. The work defines a disease mechanism whereby early malformation of the cochlear microvasculature precedes loss of vessel integrity and decline of endocochlear potential, leading to hearing loss and hair cell death while sparing spiral ganglion cells. This provides essential information on events defining the optimal therapeutic window and indicates that early intervention is needed. In an era of advancing gene therapy and small-molecule technologies, this study establishes Ndp-mutant mice as a platform to test such interventions and has important implications for understanding the progression of hearing loss in Norrie disease

Metabolic and Crystal Arthropathies [70-72]: 70. Single Intramuscular Depot Methylprednisolone Injection: A Convenient, Efficacious and Safe Treatment for Gouty Arthritis in an Inpatient Setting

Background: Various modalities of treatment have been used and recommended in the treatment of acute gout. These include drugs such as colchicine, NSAIDs and oral prednisolone. Intramuscular depot methylprednisolone (im MP) is currently used in the treatment of rheumatoid arthritis as well as polymyalgia. However the response to im MP in acute gouty arthritis in an inpatient setting (where there are usually contraindications to NSAIDs) has not been previously described in literature. Methods: Eighteen case records of patients presenting with acute gouty arthritis and referred to Rheumatology, between October 2008 and October 2009, were reviewed. Results: Fourteen men and four women, with a mean age of 60 years (range 55-88 years) were seen. Of the 18, 14 patients had a previous history of chronic gout and 4 patients were newly diagnosed. Sixteen patients had polyarticular gout (mainly bilateral wrists and knees) and the remaining 2 had monoarticular gout (1 knee, 1 wrist). Seventeen patients had synovial fluid analysis, which revealed negatively birefringent urate crystals, and 1 patient refused joint aspiration. All patients had predisposing co-morbidities such as diabetes (10), hypertension (15), CCF (5), chronic kidney disease (8) and 2 patients had a history of chronic alcohol excess. Five patients initially received NSAIDs and 3 had concomitant colchicine with all 5 showing a delayed response. All patients were given im MP 120 mg in the gluteal region as a deep injection. All responded completely to im yMP within 2 days with resolution of pain and swelling of inflamed joints. All patients felt much improved and rated the treatment highly. Conclusions: The latest BSR guidelines recommends the use of steroids in the management of refractory cases of gout, i.e. patients intolerant of or having contraindications to NSAIDS or colchicine. This restricted indication is based mainly on the side effects to oral steroids or lack of expertise with intra-articular injections. We have shown that a single intramuscular methyl prednisolone injection is highly effective, very convenient, patient acceptable and safe treatment for gout particularly in elderly patients with multiple co-morbidities. As most cases of inpatient gout have comorbidities such as in our series with contraindications to NSAIDs, we recommend the use of im methyl prednisolone as the first-line treatment in such patients. It may be a less painful alternative to intra-articular steroid injections and safer than bigger doses of oral steroids (especially in diabetes).

Effectiveness, cost-effectiveness and cost-benefit of a single annual professional intervention for the prevention of childhood dental caries in a remote rural Indigenous community

Background The aim of the study is to reduce the high prevalence of tooth decay in children in a remote, rural Indigenous community in Australia, by application of a single annual dental preventive intervention. The study seeks to (1) assess the effectiveness of an annual oral health preventive intervention in slowing the incidence of dental caries in children in this community, (2) identify the mediating role of known risk factors for dental caries and (3) assess the cost-effectiveness and cost-benefit of the intervention. Methods/design The intervention is novel in that most dental preventive interventions require regular re-application, which is not possible in resource constrained communities. While tooth decay is preventable, self-care and healthy habits are lacking in these communities, placing more emphasis on health services to deliver an effective dental preventive intervention. Importantly, the study will assess cost-benefit and cost-effectiveness for broader implementation across similar communities in Australia and internationally. Discussion There is an urgent need to reduce the burden of dental decay in these communities, by implementing effective, cost-effective, feasible and sustainable dental prevention programs. Expected outcomes of this study include improved oral and general health of children within the community; an understanding of the costs associated with the intervention provided, and its comparison with the costs of allowing new lesions to develop, with associated treatment costs. Findings should be generalisable to similar communities around the world. The research is registered with the Australian New Zealand Clinical Trials Registry (ANZCTR), registration number ACTRN12615000693527; date of registration: 3rd July 2015

Ozone affects plant, insect, and soil microbial communities: a threat to terrestrial ecosystems and biodiversity

Elevated tropospheric ozone concentrations induce adverse effects in plants. We reviewed how ozone affects (i) the composition and diversity of plant communities by affecting key physiological traits; (ii) foliar chemistry and the emission of volatiles, thereby affecting plant-plant competition, plant-insect interactions, and the composition of insect communities; and (iii) plant-soil-microbe interactions and the composition of soil communities by disrupting plant litterfall and altering root exudation, soil enzymatic activities, decomposition, and nutrient cycling. The community composition of soil microbes is consequently changed, and alpha diversity is often reduced. The effects depend on the environment and vary across space and time. We suggest that Atlantic islands in the Northern Hemisphere, the Mediterranean Basin, equatorial Africa, Ethiopia, the Indian coastline, the Himalayan region, southern Asia, and Japan have high endemic richness at high ozone risk by 2100
