1. Autoimmune disease not associated with monoclonal gammopathy
Previous studies may have been affected by ascertainment bias
Abstract: https://www.acpjournals.org/doi/10.7326/M23-2867
URL goes live when the embargo lifts
A study of more than 75,000 persons screened for monoclonal gammopathy of undetermined significance (MGUS) found no association between the presence of autoimmune diseases and MGUS. According to the authors, these findings are clinically significant because they indicate that recommendations to routinely screen patients with autoimmune disease for MGUS may not be warranted. The findings are published in Annals of Internal Medicine.
Researchers from the University of Iceland analyzed a cross-sectional study where 75,422 adults were screened for MGUS to see if they could find an association between MGUS and autoimmune diseases. Of those screened, 10,818 had an autoimmune disease, and 599 of the patients with autoimmune diseases had MGUS. There were no differences between organ-specific and systemic autoimmune diseases or between antibody-positive and antibody-negative disorders. The authors determined that the diagnosis of an autoimmune diseases was not associated with MGUS, but it was associated with a prior clinical diagnosis of MGUS. These findings suggest that previously observed associations between autoimmune conditions and MGUS may have been affected by ascertainment bias. The authors caution that studies based only on clinical MGUS cohorts that are very likely to have been identified through work-up of the same diseases with which an association is being sought has led to a false association.

2. Definitions and models of care for long COVID remain unclear
Abstract: https://www.acpjournals.org/doi/10.7326/M24-0677
URL goes live when the embargo lifts
A scoping review of 38 published articles related to the definition and care of long COVID found differences between reported definitions and models of care for the condition. The authors say that a standardized, valid, and reliable definition is needed to accurately identify patients with the condition and to develop and study the potential benefit of various long COVID models of care. The review is published in Annals of Internal Medicine.
Researchers from Oregon Health & Science University studied reviews describing long COVID definitions or models of care to provide an overview of care models, including a proposed framework to describe and distinguish models. The authors found that five clinical definitions of long COVID varied with regard to timing since symptom onset and the minimum duration required for diagnosis; 1 additional definition was symptom score–based. The authors also evaluated the research to create a framework of care models. They identified 10 representative practice-based and 3 systems-based models of care using this method. In addition, many of the models managed care for either adults or children, and managed care for uninsured or underinsured patients but were not designed to do so. They note that given the high demand for long COVID care, models that increase capacity are a high priority. They also note that although integration of long COVID management into primary care is a potential strategy to increase capacity, challenges include the need to ensure appropriate training, increase primary care engagement, and ensure sufficient staff and specialist support.

3. AI tool useful but not a replacement for human screening of the literature for systematic reviews

An analysis of the AI tool GPT 3.5 Turbo found that it may be used as a second reviewer for title and abstract screening and may reduce the number of citations before screening by humans at the cost of creating additional work by adding false positives and missing citations. The analysis is published in Annals of Internal Medicine.
Researchers from the Centre for Research in Epidemiology and Statistics (CRESS) conducted an analysis to investigate the sensitivity and specificity of GPT-3.5 Turbo, as a single reviewer, for title and abstract screening in systematic reviews. The authors developed a framework to guide the model in its screening process using 5 prompts evaluating a different component of the PICOS (Population, Intervention, Comparison, Outcomes, and Study design) framework. The model screened 5 systematic reviews representing 22,665 citations. They found that the current performance of GPT-3.5 Turbo models is insufficient to fully replace manual screening in systematic reviews but it could be used to assist reviewers to help them deal with uncertainties and could be used to reduce the number of citations before title and abstract screening by humans. However, according to the authors, use of these models is currently limited by their lower specificities compared with human reviewers, the fact that performance depends on the prompts and therefore the need for prompt engineering, and the limited reproducibility of outputs.
The authors of an editorial from the University of Colorado and Annals of Internal Medicine cautions that time efficiencies gained through GPT may be offset by the time invested in prompt engineering and the reconciliation of false positives. They also note that the limited number of reviews included in this study may make it difficult to determine what characteristics may affect performance. They advise several avenues for future research on the use of GPT in research processes.

Yoga and meditation-induced altered states of consciousness are common in the general population
2024-05-20
BOSTON--Yoga, mindfulness, meditation, breathwork, and other practices are gaining in popularity due to their potential to improve health and well-being. The effects of these practices are mostly positive and occasionally transformational, yet they are known to sometimes be associated with challenging altered states of consciousness.
New research by a team including investigators from Massachusetts General Hospital, a founding member of the Mass General Brigham healthcare system, reveals that altered states of consciousness associated with meditation practice are far more common than expected.
Although many people reported positive outcomes, that were sometimes even considered ...
UCF researcher is developing algorithms to further space, sea exploration
2024-05-20
Cislunar space, which stretches from the Earth to just beyond the moon’s orbit, is about to become heavily trafficked over the next 10 years. With NASA’s planned Artemis missions and other countries joining in the cislunar space race, there’s an interest in observing, tracking and predicting the orbit of objects like asteroids and satellites so they don’t collide with spacecraft.
But the process of detecting and observing space objects, known as space domain awareness (SDA), faces challenges with the extensive volume of cislunar space.
“Cislunar space is vast,” says Tarek Elgohary, an associate professor ...
Illuminating neuro-vascular dynamics throughout the body: 3D-printed implants and bioluminescence duet shed light on brain–spinal interactions
2024-05-20
A sensory process such as pain is no ordinary phenomenon—it’s a symphony of neural and vascular interactions orchestrated by the brain and spinal cord. Attempting to dissect this symphony by focusing on a single region is like trying to understand a complex melody by listening to just one instrument. It’s incomplete, potentially misleading, and may result in erroneous conclusions.
Enter the Carney Institute’s team of visionaries. Their mission? To develop tools that allow unprecedented observation of neural and vascular activity within the brain and spinal cord. They tackled two critical fronts: imaging hardware and bioluminescent (BL) molecular tools.
Innovative ...
Studies show linked biological pathways driving skin inflammation
2024-05-20
A certain biological pathway, a set of linked reactions in the body, drives the inflammation seen in the skin disease psoriasis, a new study finds. The work could lead to improved therapies for all inflammatory skin diseases, including atopic and allergic dermatitis and a type of boil called hidradenitis suppurativa, say the study authors. Inflammation is the body’s natural response to irritation and infection, but when out of control, it can lead to the reddish, flaky, itchy lesions that come with these skin diseases.
Led by researchers at NYU Langone Health, the new study found that the interleukin-17 (IL-17) pathway, ...

Pioneering research study makes significant contributions toward addressing the shortage of suitable knee meniscus and TMJ disc replacements
2024-05-20
The shortage of suitable donor meniscus grafts from the knee and temporomandibular joint (TMJ) impedes treatments for millions of patients. Vitrification offers a promising solution by transitioning these tissues into a vitreous state at cryogenic temperatures, protecting them from ice crystal damage using high concentrations of cryoprotectant agents (CPAs). However, vitrification's success is hindered for larger tissues (>3 mL) due to challenges in CPA penetration. Dense avascular meniscus tissues require extended CPA exposure for adequate penetration; however, ...
By listening, scientists learn how a protein folds
2024-05-20
CHAMPAIGN, Ill. — By converting their data into sounds, scientists discovered how hydrogen bonds contribute to the lightning-fast gyrations that transform a string of amino acids into a functional, folded protein. Their report, in the Proceedings of the National Academy of Sciences, offers an unprecedented view of the sequence of hydrogen-bonding events that occur when a protein morphs from an unfolded to a folded state.
See video: Protein Sonification
“A protein must fold properly to become an enzyme or signaling molecule or whatever its function may be — all the many things that proteins do in our bodies,” said University of Illinois ...
