Study indicates possible link between chronic stress and Alzheimer’s disease
Researchers have published a study that addresses possible associations between chronic stress, mild cognitive impairment and Alzheimer’s disease. The study shows how people aged between 18 and 65 with a previous diagnosis of chronic stress and depression were more likely than other people to be diagnosed with mild cognitive impairment or Alzheimer’s disease.
Heavily mutated SARS-CoV-2 variant BA.2.86 not as resistant to antibodies as first feared
Researchers who studied SARS-CoV-2 variant BA.2.86, found that the new variant was not significantly more resistant to antibodies than several other variants that are circulating. The study also showed that antibody levels to BA.2.86 were significantly higher after a wave of XBB infections compared to before, suggesting that the vaccines based on XBB should provide some cross-protection to BA.2.86.
Allergy study on 'wild' mice challenges the hygiene hypothesis
The notion that some level of microbial exposure might reduce our risk of developing allergies has been termed the hygiene hypothesis. A new study challenges this hypothesis by showing that mice with high infectious exposures from birth have the same, if not an even greater ability to develop allergic immune responses than 'clean' laboratory mice.

Sentenced to care - punishment or opportunity?
In 2022, roughly 350 people were sentenced to forensic psychiatric care. There is a unique borderland between the judicial system and healthcare, in which a person who has completed their medical treatment can be prevented from being discharged. At the same time, many patients are saying that they have benefited from the care. And fewer people relapse into crime after they have received forensic psychiatric care than they do after being imprisoned.
Early treatment of child obesity is effective
The early treatment of obesity in children is effective in both the short and long term, researchers from Karolinska Institutet report in a study published in International Journal of Obesity.
Researchers present novel principle for nitric oxide-mediated signalling in blood vessels
Although a simple molecule, nitric oxide is an important signal substance that helps to reduce blood pressure by relaxing the blood vessels. But how it goes about doing this has long been unclear.
No increase in cancer risk for most patients with reflux disease
Reflux disease manifests as acid regurgitation and heartburn and is a known risk factor for oesophageal cancer. However, new findings published in The BMJ show that the cancer risk is only elevated in patients with inflammation in the oesophageal mucus membrane.
Risk of brain haemorrhage appears transmissible via blood transfusion
A major study published in JAMA led by researchers at Karolinska Institutet suggests that a possible cause of spontaneous brain haemorrhage could be transmitted via blood transfusion. At the same time, it is very unlikely that anyone should suffer a brain haemorrhage after receiving donated blood.
KI climbs furthest in this year’s university Reputation Index
