A new study published in JAMA Otolaryngology–Head & Neck Surgery has found that deficits in the sense of smell, known as olfactory impairment, are significantly associated with increased mortality in older adults. The findings, based on data from over 2,500 participants in the Swedish National Study on Aging and Care in Kungsholmen, suggest that olfactory testing could serve as a valuable early indicator of broader health decline.

Bacterial resistance negates the effect of antibiotics in the treatment of infection. Using mouse models, researchers now show that if antibiotics are administered with an enzyme called endolysin, the combined effect protects against infection by resistant bacteria in all bodily organs – including the brain, which antibiotics alone have difficulty reaching. The results are reported in the journal Molecular Medicine.

In chronic lymphocytic leukemia (CLL), certain recurrent genetic alterations are known to influence disease progression and survival. One important abnormality is the loss of part of chromosome 11, del(11q), which is associated with a more aggressive disease course. However, it has remained unclear whether mutations in the ATM gene, which is also located in this region, have a similar impact.

KI researcher Pauliina Damdimopoulou is currently experiencing a lot of activity. At the end of April this year, she was appointed ERC ambassador — and just a few days later, she became a professor of reproductive biology at the Department of Women's and Children's Health. Now she looks forward to building new collaborations to strengthen research on women's and children's health.

A team of international researchers led by Karolinska Institutet has revealed in unprecedented detail how tetracycline antibiotics impair T cell function by binding mitochondrial ribosomes and inhibiting oxidative metabolism (OXPHOS). The study, reported in Nature Communications, raises mechanistic considerations for antibiotic therapy and the design of new molecules that can better discriminate between pathogen and host.

KI Professor Anna Mia Ekström joins the KIB podcast in a conversation about the Face of AIDS Film Archive, the unique film archive documenting the global HIV epidemic 1986-2021. We talk about the importance of the current political landscape in the fight against HIV and AIDS, the results achieved in terms of treatment and the very real risk that these results will be reversed. We talk about the role of documentation and activism: ‘We don't see that today [...] and we know that silence kills.'
