Sweden is one of the few countries that have removed the dental health recommendation to give prophylactic antibiotics to people at a higher risk of infection of the heart valves, so-called infective endocarditis. Since the recommendation was removed in 2012, there has been no increase in this disease, a registry study from Karolinska Institutet published in the journal Clinical Infectious Diseases shows.

Researchers from Karolinska Institutet have analysed blood and sperm samples from healthy parents to children with genetic syndromes and the results indicate that germline mosaicism is underestimated as a cause to syndromes and that the level of the genetic variant is higher in sperm than in blood.  The study was recently published in Molecular Genetics & Genomic Medicine.

Erik Vismer and his wife sought help from an IVF clinic to get children. What they didn’t expect was the effort and time that the process demanded from them. Read an in-depth article series from KI’s Swedish popular science magazine.

Medication for Parkinson's disease reduces many of the symptoms that affect patients, but often the problems associated with impaired balance and increased risk of falls and injuries remain. A new study in the journal NPJ Parkinson's Disease provides an in-depth picture of balance training as a treatment for Parkinson's. The partly disappointing results suggest that exercise programmes may need to be intensified or personalized to a greater extent, and that more research is required.
