Study highlights optimal timing for assessing orthostatic hypotension in older adults and its impact on fall risk

2023-11-06
(Press-News.org) A new study, "Timing of Orthostatic Hypotension and its Relationship with Falls in Older Adults", has brought critical insights into the assessment of orthostatic hypotension, a drop in blood pressure commonly found among older adults when transitioning from a sitting or lying position to a standing position that can lead to dizziness and falls.

Published in the Journal of the American Geriatrics Society (JAGS) and based on a secondary analysis of the "Study to Understand Fall Reduction and Vitamin D in You (STURDY)," this study examined the prevalence of orthostatic hypotension at different time points after standing in a population of older adults, and it also explored the association between orthostatic hypotension and fall risk.

Key findings from the study, which involved community-dwelling adults aged 70 and older, revealed that orthostatic hypotension was most prevalent and symptomatic within 1-2 minutes after standing. However, the study also demonstrated that orthostatic hypotension assessments conducted after 4 to 6 minutes of standing were more informative for predicting fall risk.

According to Lewis A. Lipsitz, MD, Director, Hebrew SeniorLife Marcus Institute for Aging Research and Hebrew SeniorLife’s Chief Academic Officer, “The findings have important implications because falls represent a major cause of serious, life-threatening injury in older adults, and understanding the timing of orthostatic hypotension assessments can help clinicians identify those at highest risk and institute appropriate interventions to reduce falls and related injuries.”

RIT researcher looks for genetic switch to prevent ‘sleeping sickness’ in cattle

2023-11-06
As parasites adapt to a warming world, an infectious disease expert at Rochester Institute of Technology has his eye on the tsetse fly in sub-Saharan Africa. The biting fly transmits Trypanosomiasis, or “sleeping sickness,” to cattle there and could someday migrate to northern climates, including to the United States. RIT researcher Bolaji Thomas is leading a $650,000 study funded by the U.S. Department of Agriculture, the National Institute of Food and Agriculture, and the Agriculture ...

Improving the efficacy of cancer immunotherapy with modified CAR-T cells

2023-11-06
CAR-T cell therapy is a last hope for many patients with blood, bone marrow or lymph gland cancer when other treatments such as chemotherapy are unsuccessful. A limiting factor of this otherwise very effective and safe therapy is that the cells used in the process quickly reach a state of exhaustion. Researchers at the University of Freiburg have now been able to prevent this exhaustion and thus significantly improve the effect of the therapy in a preclinical animal model. The new results have been published in the journal Nature Immunology. Using the body’s own defences ...

UMD researchers developed a nasal vaccine that prevents COVID in preclinical studies

2023-11-06
A team of University of Maryland researchers developed a nasal spray vaccine that delivers the SARS-CoV-2 spike protein into cells of the airway in mice and hamsters, triggering an immune response that significantly reduced infection and spread of COVID-19. The technology can be adapted to induce immunity to other respiratory illnesses, such as influenza and respiratory syncytial virus (RSV) infections. A nasal vaccine for respiratory viruses would be a significant improvement over intramuscular shots, because they are less invasive and stop viral particle replication in the airway, before a virus can enter the bloodstream. This could improve the rate ...

Learning more about how flu strains evolved may help guide future vaccine development – SFU research

2023-11-06
Simon Fraser University researchers studying the evolutionary history of flu viruses have found that a new quantitative analysis of how they evolved may help predict future strains. The research draws on a field known as phylogenetics, which focuses on how groups of organisms are evolutionarily related, and is published in the journal Science Advances. Researchers used large phylogenetic ‘trees’ to predict which strains are most likely to grow during the upcoming flu season, and determined that this approach was moderately effective in detecting future strains of the influenza virus, and could be another tool in the toolbox to guide seasonal ...
