Reduced dental anxiety among children with internet-based CBT

Tuesday January 23rd, 2018 10:35:27 AM

Researchers at Karolinska Institutet have developed an accessible therapy for children and adolescents suffering from dental phobia. The study, published in the Journal of Medical Internet Research, shows that guided internet-based CBT is highly effective in reducing anxiety and increasing the ability to deal with dental treatment. One year later, half of the children were completely free of their phobia.

Dental anxiety often begins in childhood or adolescence, and can develop into a phobia with avoidance, strong negative feelings and thoughts aimed at dental care. Avoidance of dental care often leads to poor oral health, untreated caries or other dental problems.

Cognitive behavioural therapy (CBT) is an effective treatment for most forms of specific phobia. However, with regard to children and adolescents with dental phobia, there are organisational, financial and geographic obstacles to providing such therapy. Researchers in this study have therefore developed an internet-based CBT treatment that they have tested in an open, uncontrolled study of 18 patients between the ages of 8 and 15.

Treatment continued for 12 weeks

During the study, participants used an internet platform to obtain weekly online guidance from a psychologist via a chat system. Treatment continued for 12 weeks and included texts, animations and dental-related video clips. The treatment also included an exercise package with a dental mirror, probe, local anaesthetic and cannula delivered to the home of the child/parent(s) with detailed instructions for the exercises. Through therapy and guidance from the psychologist, the home-based exercises were linked to real exposure and training visits to dental clinics around Sweden.

The results show a statistically and clinically-significant increase in the children’s ability to manage dental treatment. The internet-based CBT also increased children’s and parents’ self-efficacy, led to fewer negative thoughts and reduced anxiety aimed at dental treatment. At a one-year follow up, 53 per cent of the children were completely free of their dental phobia.

Surprisingly strong effects

“Even though we expected positive effects from the therapy, it was still surprising to see the scope of improvement and the strong effects of the therapy among the patients, given that they did not have a single physical meeting with the psychologist,” explains Shervin Shahnavaz at Karolinska Institutet’s Department of Dental Medicine who is the researcher behind the development of the therapy.

The researchers now hope to be able to repeat the results in an ongoing randomised controlled trial.

“Internet-based CBT for dental phobia in children and adolescents may be an efficient form of therapy with the potential to increase access to effective treatment,” says Dr Shahnavaz.

The study is the result of a collaboration with Stockholm County Council’s unit for internet psychiatry. The research project was supported with grants from SOF; board of dental research at Karolinska Institutet and Stockholm County Council and the Mayflower Charity Foundation for children.

Demonstration for Ahmadreza Djalali

Friday January 19th, 2018 09:28:06 AM

On Thursday, Amnesty International’s Swedish section and Karolinska Institutet held a joint demonstration in support of the physician and researcher Ahmadreza Djalali, currently facing a death sentence in Iran.

The demonstration in support of Ahmadreza Djalali, who has been imprisoned in Iran since April 2016, was held at Campus Solna. Ahmadreza Djalali’s wife, Vida Mehrannia, also attended the demonstration.

Ahmadreza Djalali was sentenced to death in October 2017 for alleged espionage on behalf of the Israeli government. Although Djalali is an Iranian citizen, he has a permanent residence permit in Sweden and was previously a researcher in disaster medicine at Karolinska Institutet, where he also defended his thesis in 2012.

Amnesty International considers Ahmadreza Djalali to be a prisoner of conscience who has been arbitrarily imprisoned and is demanding that the Iranian authorities quash the sentence and release him.

Ole Petter Ottersen, Vice-Chancellor of Karolinska Institutet, participated in the demonstration. Among other things, he spoke of the human right to a free and just trial, the fact that the death penalty conflicts with human dignity, human rights and international standards, as well as every value for which Karolinska Institutet stands.

“As academics, we have a great responsibility towards the fight to abolish the death penalty and to maintain academic freedom, so let us make ourselves heard,” declared Ole Petter Ottersen.

In 2014, during his time as vice-chancellor of the University of Oslo, Ole Petter Ottersen was instrumental in starting the Universities Against the Death Penalty network.

During the demonstration, Anna Lindenfors, Director at Amnesty International Sweden, explained that, as the Supreme Court of Iran confirmed the death penalty in December, the only remaining possibility is a judicial review of the entire case that may change the verdict.

“This is a very serious situation. Ahmadreza Djalali must be immediately and unconditionally released so that he can be reunited with his wife and children in Sweden and continue his research,” said Anna Lindenfors.

Lisa Kurland, previously Djalali’s supervisor and professor in emergency care at Örebro University, contributed a more personal picture of her friend and colleague.

“Ahmadreza Djalali travelled to Iran, the land of his birth and a country he loved, in order to pass on his knowledge. It pains me that he is imprisoned, and it is beyond comprehension that he is sentenced to death,” she said.

Michael Landreh, David Lane, Sonia Lain, Marcus Ladds et al publish in Cell Chemical Biology

Friday January 19th, 2018 08:28:52 AM
John Sennett

In a study published in Cell Chemical Biology this week, researchers from MTC (Michael Landreh, David Lane, Sonia Lain, Marcus Ladds et al), KTH, Uppsala University, and the University of Oxford, used a new strategy to find out how anticancer drugs bind to the membrane protein dehydroorotate dehydrogenase (DHODH), a new cancer target.

The groups of Sir David Lane and Sonia Lain at the Department of Microbiology, Tumor and Cell Biology at Karolinska Institutet used native mass spectometry, a technique where a protein is gently removed from its normal environment and accelerated into a vacuum chamber. By measuring the time it takes for the protein to fly through the chamber, it is possible to determine its exact weight, which can, in turn, indicate whether the protein has bonded to another molecule and if so, what kind. The researchers used this highly accurate ”molecule scale” to see how drugs and lipids, the building blocks of the cell membrane, bind to DHODH.
