Excess mortality with Alzheimer disease and related dementias as an underlying or contributing cause during pandemic

JAMA Neurology

2023-07-17

(Press-News.org) About The Study: This study found that large increases in mortality with Alzheimer disease and related dementias as an underlying or contributing cause of death occurred in COVID-19 pandemic year 1 but were largely mitigated in pandemic year 2. The most pronounced declines were observed for deaths in nursing home/long-term care settings. Conversely, excess deaths at home and in medical facilities remained high in year 2.

Authors: M. Maria Glymour, Sc.D., of the Boston University School of Public Health in Boston, is the corresponding author.

Comparison of history of present illness summaries generated by a chatbot and senior internal medicine residents

2023-07-17

About The Study: History of present illnesses generated by a chatbot or written by senior internal medicine residents were graded similarly by internal medicine attending physicians. These findings underscore the potential of chatbots to aid clinicians with medical documentation.

Addressing adaptation inequalities in climate research

2023-07-17

A new study proposes ways to better incorporate adaptation in climate change research, addressing the uneven distribution of adaptation capacities and needs worldwide. Research on adaptation to the risks posed by climate change has witnessed significant growth in the past decade, with increasing recognition of its urgency in policy agendas at the international, national, and local levels. Adaptation needs and capacities are not evenly distributed worldwide, with countries in the Global South generally experiencing the highest challenges. ...

Heading frequency and risk of cognitive impairment in retired male professional soccer players

2023-07-17

About The Study: The findings of this study suggest that repetitive heading during a professional soccer career is associated with an increased risk of cognitive impairment in later life. Further study is needed to establish the upper threshold for heading frequency to mitigate this risk. Authors: Weiya Zhang, Ph.D., of the University of Nottingham in Nottingham, United Kingdom, is the corresponding author.

COVID-19 vaccines saved dementia patients' lives in nursing homes

2023-07-17

Deaths among older adults with dementia fell starkly in nursing homes and long-term care centers after COVID-19 vaccinations became available, yet remained high for those living at home, according to a new study led by UC San Francisco. The nationwide study published July 17, 2023 in JAMA Neurology, is the first to use data from 2019 to 2022 to quantify “excess” deaths – or those above what would have been anticipated had there been no pandemic – taking into account age, sex, racial and ethnic groups, as well as the settings where people died. In the first year, there were 509,179 dementia-related ...

Reprogramming the shape of virus capsids could advance biomedicine

2023-07-17

Bioengineers have found a way to program the size and shape of virus particles by combining viral protein building blocks and templates made from DNA. The resulting nanostructures could have applications in vaccine development and transporting drugs inside the body. Virus capsid proteins—the proteins that shield the genome of a virus—can be used to build precisely structured protein assemblies. Their shapes and geometry, however, depend largely on the virus strain. Reprogramming these assemblies, no matter the original ...

World-first clinical trial to help millions with penicillin allergies

2023-07-17

Penicillin allergy affects more than 25 million people in the United States (up to 1 in 10 Americans) and has been shown to lead to particularly poor health outcomes in pregnant women and surgical patients. It is also a public health threat, leading to antibiotic resistance and infections in hospitalized patients that can be life threatening. Seventy-five% or more penicillin allergy labels come on by age 3 due to, for example, confusion with a viral rash. The majority of these rashes were never allergic, but the labels ‘stick’ into adulthood and carry many adverse consequences.” Many low-risk patients with a penicillin allergy were able to have their ...

Scent dogs can detect COVID-19 more rapidly and accurately than current tests

2023-07-17

Scent dogs may represent a cheaper, faster and more effective way to detect COVID-19, and could be a key tool in future pandemics, a new review of recent research suggests. The review, published in De Gruyter’s Journal of Osteopathic Medicine, found that scent dogs are as effective, or even more effective, than conventional COVID-19 tests such as RT-PCR. Dogs possess up to 300 million olfactory cells, compared to just 5 or 6 million in humans, and use one-third of their brains to process scent information, ...

Robotics: New skin-like sensors fit almost everywhere

2023-07-17

“Detecting and sensing our environment is essential for understanding how to interact with it effectively,” says Sonja Groß. An important factor for interactions with objects is their shape. “This determines how we can perform certain tasks,” says the researcher from the Munich Institute of Robotics and Machine Intelligence (MIRMI) at TUM. In addition, physical properties of objects, such as their hardness and flexibility, influence how we can grasp and manipulate them, for example. Artificial hand: interaction with the robotic system The ...

Team fabricates chitin hydrogel via chemical transformation of chitosan

2023-07-17

Chitin hydrogel is recognized as a promising material for a variety of biomedical applications. Its biocompatibility and biodegradability make it useful in tissue repair, artificial organs, and wound healing. Yet scientists continue to face challenges in fabricating chitin hydrogel. A team of researchers has developed a green, efficient and scalable preparation method for chitin hydrogels. The team’s work provides a rational strategy to fabricate chitin hydrogels and paves the way for its practical applications as a superior biomedical material. Their ...

Report highlights public health impact of serious harms from diagnostic error in US

2023-07-17

Improving diagnosis in health care is a moral, professional and public health imperative, according to the U.S. National Academy of Medicine. However, little is known about the full scope of harms related to medical misdiagnosis — current estimates range widely. Using novel methods, a team from the Johns Hopkins Armstrong Institute Center for Diagnostic Excellence and partners from the Risk Management Foundation of the Harvard Medical Institutions sought to derive what is believed to be the first rigorous national estimate of permanent disability and death from diagnostic error.  The original research article ...
