SCAHT goes to South America
Following the successful regulatory sciences course held in 2013, SCAHT was approached to organize a one-week course in regulatory toxicology adapted to the needs of Brazilian scientists concerned with the registration of agrochemicals. The course was held from 29 June - 3 July in Brasilia with 28 participants from the regulatory authority, the agrochemical industry, and Brazilian and Columbian universities. The faculty included Rex FitzGerald and Martin Wilks from SCAHT as well as Neil Byron (Exponent) and Elizabeth de Souza Nascimento (University of Sao Paulo). The course was well received by the participants, and the hope was expressed that similar courses could be conducted elsewhere in South America.
Research in SCAHT: Acute health problems due to recreational drug use
Dr. Liakoni and Prof. Liechti from the Division of Clinical Pharmacology at the University Hospital Basel investigated acute medical problems due to recreational substance use in patients presenting to the emergency department (ED). Among the 47.767 attendances at the ED during one year, 216 were directly related to acute toxicity of recreational drugs. The most common recreational drugs were cocaine and cannabis. During the study period only 2 cases were related to the use of novel psychoactive substances. The most commonly reported symptoms were tachycardia (31%), anxiety (27%), nausea or vomiting (23%), and agitation (22%). Additionally, there were two cases of myocardial infarction, 10 cases of seizures, and 10 cases of psychosis. Among all cases 40 (19%) presented with severe intoxication and there was one fatality. Emergency department presentations associated with novel psychoactive substances appear to be relatively rare. Further information.

SCAHT Newsletter 05/2014 (December 2014)
Wednesday, December 17, 2014 - 11:58
The year 2014 has seen momentous changes for the SCAHT. In February the 'Foundation of the Swiss Centre for Applied Human Toxicology' was officially registered with the Registre du Commerce de Genève, giving the SCAHT its legal framework for the future. In November we celebrated the 5th anniversary of the SCAHT. In between, SCAHT staff and members have been busier than ever with research and regulatory projects, teaching and contributions to national and international activities in human health risk assessment. From all of us at SCAHT, a big thank you for making our anniversary year a great one! We wish you and your families a peaceful Christmas and a very happy New Year 2015, and look forward to continuing our successful collaboration.
Happy 5th Birthday, SCAHT!
Five years ago, with an inaugural symposium on 19 November 2009 in Geneva, the Swiss Centre for Applied Human Toxicology was born. To celebrate its 5th birthday, SCAHT held an anniversary symposium on 14 November 2014 in Basel, at the annual meeting of the Swiss Society of Toxicology. Toxicologists and honored guests listened to welcoming words from National Councillor Prof. Kathy Riklin, Prof. Stefan Krähenbühl, co-founder of the SCAHT, and Prof. Martin Wilks, the SCAHT director. Keynote lectures were given by Prof. Alan Boobis and Prof. Angelo Moretto, both members of the SCAHT Science Advisory Board, and SCAHT Research Group Leaders presented overviews of their work on neuroinflammation, nanoparticle drug delivery, human steroid profiling, and development of in vitro cell cultures to replace animal testing.

Participation in Annual EPAA Conference
SCAHT attended the 10th annual conference of the European Partnership for Alternative Approaches to Animal testing (EPAA) on the 19th November in Brussels. Over 100 stakeholders from academia, NGOs, industry and EU institutions attended the event to discuss how to facilitate the use of alternative methods by regulators. It is one of the objectives of the SCAHT to foster a collaborative working relationship between Swiss regulatory authorities and SCAHT researchers who also develop alternative testing methods.
Research in SCAHT: Bisphenol A - Why an adverse outcome pathway framework needs to be applied
Bisphenol A (BPA) is one of the most widely used and extensively studied chemicals. Numerous studies have reported in vitro effects or animal adverse findings at BPA doses lower than the no observed adverse effect levels (NOAELs) established in regulatory toxicity studies and used for human health risk assessment. Intensive discussions on the adequacy and relevance of test systems have not satisfactorily resolved whether positive or negative animal and/or in vitro findings are more relevant for human health risk assessment purposes. In this article for a special issue of Toxicology Letters on 'Environmental contaminants and target organ toxicities', SCAHT regulatory toxicologists Rex FitzGerald and Martin Wilks argue that a structured approach like the OECD Adverse Outcome Pathway (AOP) framework is needed to help researchers in designing relevant studies, and risk assessors in evaluating them. Establishing AOPs for BPA, and other endocrine active chemicals, will require major scientific as well as training investments by all responsible stakeholders. Further information.
