Some children are born with hearing loss in only one ear. What to do then? The issue is more difficult than one might think.

One billion young people risk hearing loss in the future if they continue to listen to their headphones at too high a volume. To develop treatments, researchers need to solve the mysteries of the cochlea - well hidden in the inner ear, a pea-sized organ embedded in bone a few centimeters inside the outer ear.

The summer heat is here and with it questions about how we should handle high temperatures and what we should do to feel well in the heat. Cardiologist Petter Ljungman, associate professor at the Institute for Environmental Medicine and expert coordinator at the Centre for Health Crises, answers questions about health and heat.

Global Disaster Medicine - Health Needs and Responses is part of a consortium led by the Swedish Civil Contingencies Agency, called IPA Care, that aims to address the needs of countries on Western Balkan, along with Turkey, to strengthen their ability to prevent risks related to earthquakes and other health emergencies.

A groundbreaking study published in Nature Cardiovascular Research uncovers the crucial role of the AmotL2 protein in connecting mechanical forces to endothelial cell integrity and alignment. This discovery sheds light on junctional mechanotransduction and its implications for vascular disease, including abdominal aortic aneurysms (AAA). Importantly, the study reveals gender differences, with males showing a higher incidence of AAA.

An international team of researchers has developed a new method to deliver drugs into the inner ear, according to a new study in Science Translational Medicine. The discovery was possible by harnessing the natural flow of fluids in the brain and employing a little-understood backdoor into the cochlea. When combined to deliver a gene therapy that repairs inner ear hair cells, the researchers were able to restore hearing in deaf mice.

A new study in Nature by an international team including researchers at Karolinska Institutet has identified the first genetic variant associated with disease severity in multiple sclerosis. The finding opens the door to the development of treatments that fight disease progression – a great unmet need facing people with MS.

The funds will be distributed over five years, with the potential for another five years of funding after evaluation.

Researchers at Karolinska Institutet have identified a group of nerve cells in the mouse brain that are involved in creating negative emotional states and chronic stress. The neurons, which have been mapped with a combination of advanced techniques, also have receptors for oestrogen, which could explain why women as a group are more sensitive to stress than men. The study is published in Nature Neuroscience.

Federico Iovino and his lab members have been awarded with a grant from the ItsME Foundation to enable their research on the prevention of neuronal damage caused by bacterial infections.

A team of researchers at Karolinska Institutet and Yale School of Medicine wanted to know what happens to mosaic skin upon injury. Do simple wounds or surgery enhance the skin cancer risk by expanding mutated cells even more as generally believed? The surprising answer is no, according to newly published study in Nature.

In the middle of May, around 30 students and three teachers from The School of Health Sciences, Western University, Ontario, Canada, visited the study programmes in health care sciences at NVS. This is part of a collaboration that started on a smaller scale in 2018, and after a short break during the pandemic is back on track since last year.

In June 2023 representatives from Karolinska Institutet visited Washington DC and New York City in the US. Connected to several collaborations important to KI and with strategic plans to increase alumni activity in the US, the visit included a SIREUS event hosted at the House of Sweden in DC, as well as two planned alumni events in DC and New York, along with valuable alumni visits to Rockefeller University and Memorial Sloan Kettering Cancer Center.

Almost a hundred experts from 27 countries took part in a hackathon on June 17–18 to identify diseases in 14 patients lacking diagnoses. “Four of them have now received an answer and we’re confident that more are to come,” says professor and consultant Ann Nordgren, who was one of the organizers of the event.

In a nationwide Swedish study of more than 85,000 patients with biopsy-confirmed inflammatory bowel disease (IBD), researchers from Karolinska Institutet and Örebro University (Sweden) observed that IBD patients had an increased risk of stroke, especially of ischaemic events, compared to the general population. The results are published in Neurology.

Many men in northern Europe over the age of 60 suffer from the so-called Viking disease, which means that the fingers lock in a bent position. Now researchers at Karolinska Institutet, together with colleagues, have used data from over 7,000 affected individuals to look for genetic risk factors for the disease. The findings, which have been published in Molecular Biology and Evolution, show that three of the strongest risk factors are inherited from Neanderthals.

The study has recently been published in the journal Microbiome.

KI-Region Stockholm is the ALF region that best meets the quality criteria in the National Board of Health and Welfare’s evaluation of academic healthcare (USV). The results of the evaluation were compiled into a report published on 31 May. Research is the Stockholm region’s strongest area, but the report also comments positively on its innovation, pedagogics education and interaction with patients and their families.

Nasopharyngeal carcinoma (NPC) is a type of cancer that occurs in the nasopharynx, which is located behind the nose and above the back of the throat. NPC has a geographically skewed distribution worldwide, with high incidence rates in East and Southeast Asia. NPC is difficult to detect early, and treatment usually involves radiation therapy, chemotherapy or a combination of the two.

Forte is allocating SEK 160 million to research on the health and well-being of older people. The funds are divided into three programme grants and 19 project grants and the research will begin in 2023 and continue until 2029. Two researchers at the Aging Research Center (ARC), Karolinska Institutet, have been granted funding for their important research within the ageing research area.

Older autistic adults have a significantly higher risk of injury, especially self-inflicted, and physical conditions such as type 2 diabetes, anaemia, heart failure and COPD. This is according to a large-scale registry study from Karolinska Institutet published in The Lancet Healthy Longevity.

Our skin contains specialised long-lived killer cells that protect against intruders. Researchers at Karolinska Institutet and the University of Copenhagen have now identified how these cells are formed, and shown that high levels of memory killer cells in cancer tissue correlate with a better survival rate in people with melanoma. The study is published in the journal Immunity.

In a new study, researchers at Karolinska Institutet show that recombinant spider silk protein hydrogels have many attractive features. They allow encapsulation of cells and bioactive molecules simply by incubation at 37°C. They are transparent, which allows monitoring of encapsulated cells, and the fibrillar network mimics that of the extracellular matrix. The mechanical properties of these hydrogels match those of different tissues, and the gels can be used for continuous drug release.

Shared first authors are sisters Angiza and Bahira Shahim, who also presented the results of the study at the Heart Failure International Conference in Prague.

Older people with ischemic heart disease have an increased long-term risk of dementia and accelerated cognitive decline. A recent study published in Alzheimer's & Dementia: The Journal of the Alzheimer's Association, suggests that the heart, the brain, and cognitive function are connected in the ageing process and that appropriate prevention and treatment of ischemic heart disease in older people might reduce the burden of dementia.
