Mosquito net safe to use in inguinal hernia repair

14 January, 2016 - Karolinska Institutet

Sterilised mosquito nets can replace costly surgical meshes in the repair of inguinal (groin) hernias without further risk to the patients. This makes mosquito nets a good alternative for close to 200 million people in low-income countries suffering from untreated groin hernias. These are the results of a Swedish-Ugandan study presented in the prestigious New England Journal of Medicine (NEJM).

Many unexpected genetic variants hamper personalised medicine

16 December, 2015 - Karolinska Institutet

In recent decades, much hope was based on the development of personalised drug treatments, in which genetic tests determine the choice and optimal dose of medication for each individual patient. However, the real breakthrough is still to be seen, and now researchers at Karolinska Institutet show in two separate scientific papers that many more gene variants affect how a person responds to medication than previously thought – and thus that today’s analytical tools are too coarse.

New test for prostate cancer significantly improves screening

10 November, 2015 - Karolinska Institutet

A study from Karolinska Institutet in Sweden shows that a new test for prostate cancer is better at detecting aggressive cancer than PSA. The new test, which has undergone trial in 58,818 men, discovers aggressive cancer earlier and reduces the number of false positive tests and unnecessary biopsies. The results are published in the scientific journal ‘The Lancet Oncology’.

One step closer to a new drug for alcohol dependence

14 October, 2015 - Karolinska Institutet

Researchers at Karolinska Institutet and the Sahlgrenska Academy in Sweden might be one step closer to finding an effective drug for alcohol dependence. In two separate studies, they show that the so-called dopamine stabilizer OSU6162 can reduce the craving for alcohol in alcohol dependent people and normalises the level of dopamine in the brain reward system of rats that have consumed alcohol over a long period of time. However, thorough clinical studies are needed to determine if the OSU6162 also can help alcohol dependent people drink less alcohol.

Blood vessel cells help tumours evade the immune system

24 August, 2015 - Karolinska Institutet

A study by researchers at Karolinska Institutet is the first to suggest that cells in the tumour blood vessels contribute to a local environment that protects the cancer cells from tumour-killing immune cells. The results, which are being published in the Journal of the National Cancer Institute, can contribute to the development of better immune-based cancer therapies.

How cancer tricks the lymphatic system into spreading tumours

11 May, 2015 - Karolinska Institutet

Swollen lymph nodes are often the earliest sign of metastatic spread of cancer cells. Now cancer researchers and immunologists at Sweden’s Karolinska Institutet have discovered how cancer cells can infiltrate the lymphatic system by ‘disguising’ themselves as immune cells (white blood cells).

Gene variant determines early or late onset of Huntington’s disease

5 May, 2015 - Karolinska Institutet

Researchers at Sweden’s Karolinska Institutet and the University of British Columbia, Canada, have identified a gene variant that influences whether Huntington’s disease breaks out earlier or later than expected. The findings, which are published in the scientific journal Nature Neuroscience, can contribute to improved diagnosis and disease-modifying therapies. A typical symptom of the inherited, progressive, […]

New knowledge on EphB signalling may improve treatment of intestinal cancers

2 April, 2015 - Karolinska Institutet

[PRESS RELEASE 4/2/2015] A new study led by researchers at Sweden’s Karolinska Institutet and Nanyang Technological University in Singapore, provides experimental evidence that a drug that inhibits the EphB-signalling pathway in the cell effectively can suppress the development of intestinal tumours. According to the investigators, this knowledge may be important in the design of new […]

Research on medical abortion and miscarriage may change international routines

27 March, 2015 - Karolinska Institutet

Two scientific studies led by researchers at Karolinska Institutet are expected to form the basis of new international recommendations for the treatment of miscarriages and medical abortions ― recommendations that may also lead to a change in clinical practice in Sweden. One of the studies, both of which are being published in the journal The Lancet, shows that it is possible to replace the clinical follow-up examinations recommended today with medical abortions that include a home pregnancy test. The other study shows that midwives can safely and effectively treat failed abortions and miscarriages in rural districts of Uganda.

How blood group O protects against malaria

10 March, 2015 - Karolinska Institutet

[PRESS RELEASE 3/10/2015] It has long been known that people with blood type O are protected from dying of severe malaria. In a study published in Nature Medicine, a team of Scandinavian scientists explains the mechanisms behind the protection that blood type O provides, and suggest that the selective pressure imposed by malaria may contribute to the variable global distribution of ABO blood groups in the human population.
