In Sweden, there are over 2 million legally owned firearms. At the same time, up to 150,000 people live with a diagnosis of dementia. In an aging society such as Sweden, legislators will face challenges in gun ownership. A new registry-based observational study by researchers from NVS, Karolinska Institutet, published in the Journal of Alzheimer’s Disease shows a need for strategies for this…
A large study from Denmark and Norway published by The BMJ sheds more light on the risk of rare blood clots in adults receiving their first dose of the Oxford-AstraZeneca Covid-19 vaccine. The findings show slightly increased rates of vein blood clots including clots in the veins of the brain, compared with expected rates in the general population. However, the researchers stress that the risk of…
Women and men are different – nobody would argue with this statement. However, in medicine, gender plays a subordinate role. Neither research, prevention nor therapy adequately reflect this difference. “This is no longer acceptable,” says internist and cardiologist Prof. Dr. Vera Regitz-Zagrosek.
In just the last two years, artificial intelligence has become embedded in scores of medical devices that offer advice to ER doctors, cardiologists, oncologists, and countless other health care providers. But how much do either regulators or doctors really know about the accuracy of these tools? A new study led by researchers at Stanford, some of whom are themselves developing devices, suggests…
Researchers running the Com-Cov study, launched in February to investigate alternating doses of the Oxford-AstraZeneca vaccine and the Pfizer vaccine, announce that the programme will be extended to include the Moderna and Novavax vaccines in a new study.
Does overcoming a SARS-CoV-2 infection protect against reinfection? The “Rhineland Study”, a population-based study conducted by DZNE in the Bonn area, is now providing new findings in this regard. Blood samples taken last year indicate that an important component of immunity – the levels of specific neutralizing antibodies against the coronavirus - had dropped in most of the study…
Body composition information derived from routine chest CTs can provide important information on the overall health of people with chronic obstructive pulmonary disease (COPD), including their risk of all-cause mortality. This is the result of a new study, published in Radiology. COPD is a group of chronic, progressive lung diseases that affect about 30 million people in the United States alone.…
Medical technology company iCAD, Inc. announced that ProFound AI for 2D Mammography might notably reduce the risk of interval breast cancer, according to a new retrospective analysis. The aim of the study was to determine if adding AI to reading mammography as a supportive tool may help in decreasing the interval cancer rate in population-based organized mammography screening programs in Germany.
People discharged from hospital after Covid-19 appear to have increased risks of diseases across multiple organs and nearly a third are readmitted to hospital in the following months, according to a new study co-led by researchers at University College London. The study, published in The BMJ, looked at nearly 50,000 people who were discharged from hospital by August last year and compared them to…
Recovery duration, co-morbidities, mortality, risk groups: A large study across multiple UK centres reports in detail on prospectively assessed outcomes of Covid-19, the so called 'Long Covid'. We spoke with two of the study's co-investigators about why so many patients are still affected after a coronavirus infection.
Tumor vaccines can help the body fight cancer. Mutations in the tumor genome often lead to protein changes that are typical of cancer. A vaccine can alert the patients' immune system to these mutated proteins. For the first time, physicians and cancer researchers from Heidelberg and Mannheim have now carried out a clinical trial to test a mutation-specific vaccine against malignant brain tumors.…
More than four in five (86%) people who were unsure or said no to a Covid-19 vaccine in December 2020 would now take one, or have already been vaccinated, finds the latest research by the Virus Watch study conducted by University College London (UCL).
A study conducted by Columbia University Mailman School of Public Health researchers reports a high global prevalence of both depression and anxiety during the Covid-19 pandemic. It also shows how the implementation of mitigation strategies including public transportation and school closures, and stay-at-home orders impacted such disorders. Results are published in Psychological Medicine.
Even as vaccines are becoming more readily available, protecting against the asymptomatic and pre-symptomatic spread of the virus (SARS-CoV-2) that causes Covid-19 is key to ending the pandemic, say two infectious disease experts at the Georgetown University Medical Center. In their Perspective, “SARS-CoV-2 Transmission Without Symptoms,” published in the journal Science, they make the case…
In what is believed to be the first published study of Covid-19 vaccine effectiveness in long-term care facilities such as nursing homes, a research team co-led by the Yale School of Public Health found a widely used vaccine is highly successful in preventing infections. Residents of such facilities, particularly those in skilled nursing facilities (SNFs), have experienced disproportionately high…
Digital Covid-19 ‘symptom checkers’ may stop some patients from getting prompt treatment for serious illness, suggests an international case simulation study. Both the US and UK symptom checkers consistently failed to identify the symptoms of severe Covid-19, bacterial pneumonia, and sepsis, frequently advising these cases to stay home, the findings indicate. The availability and use of…
In the era of social distancing, using robots for some health care interactions is a promising way to reduce in-person contact between health care workers and sick patients. However, a key question that needs to be answered is how patients will react to a robot entering the exam room. Researchers from MIT and Brigham and Women’s Hospital recently set out to answer that question. In a study…
Digital breast tomosynthesis (DBT) increases detection of breast cancer in symptomatic women under the age of 60, especially in dense breasts. A large, multi-institutional study conducted in the United Kingdom comparing the sensitivity of full-field digital mammography (FFDM), DBT, and FFDM plus DBT supports findings of two similar published studies, both conducted in China in the same time frame.
Around 50% of patients who have been hospitalised with severe Covid-19 and who show raised levels of a protein called troponin have damage to their hearts. The injury was detected by magnetic resonance imaging (MRI) scans at least a month after discharge, according to new findings published in the European Heart Journal. Damage includes inflammation of the heart muscle (myocarditis), scarring or…
The impact of Covid-19 in Africa has been vastly underestimated, warn researchers in a new study. Outside of South Africa, this is the first study to provide systematic surveillance data capturing the impact of Covid-19 in Africa. Their findings are based on polymerase chain reaction (PCR) test results for 364 deceased people of all ages at the University Teaching Hospital morgue in Lusaka,…
The continuing corona virus epidemic has impacted strongly on cancer care and research, including the delay of treatments and diagnoses as well as on trials of new therapies, and the shift in research to develop a Covid-19 vaccine. However, the session ‘Cancer research and Covid-19’, during the National Cancer Research Institute (NCRI) Virtual Showcase (online 2-3 November) looked at how UK…
The most deadly global health crisis in a century has resulted in a substantial decline in overall heart surgery volume and an unexplained increase in deaths after coronary artery bypass grafting, according to late-breaking research presented at the 57th Annual Meeting of The Society of Thoracic Surgeons.
One of the most vexing aspects of the Covid-19 pandemic is doctors’ inability to predict which newly hospitalized patients will go on to develop severe disease, including complications that require the insertion of a breathing tube, kidney dialysis or other intensive care. Knowledge of a patient’s age and underlying medical conditions can help predict such outcomes, but there are still…
Older adults about to undergo elective surgery should undertake a sustained programme of targeted exercise beforehand to counteract the muscle-wasting effects of bedrest, new research suggests. A study published by researchers in the University of Birmingham’s School of Sport, Exercise and Rehabilitation Sciences showed that short term ‘prehabilitation’ strength exercises, undertaken…
Alzheimer's disease is the most common cause of dementia. Still incurable, it directly affects nearly one million people in Europe, and indirectly millions of family members as well as society as a whole. In recent years, the scientific community has suspected that the gut microbiota plays a role in the development of the disease.
