Proportion of incorrectly established paternities has decreased over time, study finds
Determining who is the biological father of a child is a sensitive subject, but the answer can be crucial in important issues. In a nationwide study published in the
Journal of Internal Medicine, researchers from Karolinska Institutet, by using two different models, have been able to show that the proportion of incorrectly established paternities in Sweden is as low as 1.7 percent, a figure that has decreased over time.
The genetic link between a father and a child is an eternal question which, for obvious reasons, can often be difficult to determine. However, with the discovery of blood groups at the beginning of the 20th century and how these are inherited, it has been possible to obtain a reliable answer in some individual cases.

Blood type may raise odds for certain health conditions, study says
By

Certain blood types may increase a person s risk of different health problems, a new study suggests.
The research confirms some previous findings and reveals new links between blood types and diseases, according to the authors of the study published this week in the journal eLife.
Advertisement There is still very little information available about whether people with RhD-positive or RhD-negative blood groups may be at risk of certain diseases, or how many more diseases may be affected by blood type or group, said first author Torsten Dahlén, a doctoral student at Karolinska Institute in Stockholm.
New insights on how certain blood types may predispose to diseases
People with certain blood types are more likely to have blood clots or bleeding conditions, kidney stones, or pregnancy-induced hypertension, suggests a study published today in
eLife.
The study confirms previously identified connections between certain blood types and the risk of blood clots and bleeding, and makes a new connection between kidney stones and having type B blood as compared to O. The discoveries may lead to new insights on how a person s blood type may predispose them to developing a certain disease.
Previous studies have found that people with blood type A or B were more likely to have cardiovascular disease or experience a blood clot than people with type O blood, and that people with type O blood were more likely to have a bleeding condition. Others have suggested that people with certain blood types may be more susceptible to some infectious diseases.
