New rapid detection of bacteria in pediatric blood samples

2024-06-14
(Press-News.org) Atlanta, Ga. – June 14, 2023 – Researchers have demonstrated that a new technology could quickly and accurately diagnose bloodstream infections. The study findings were reported at ASM Microbe, the annual meeting of the American Society for Microbiology.

“There is a need to be able to rapidly and accurately diagnose bacteremia in newborn babies. They are especially susceptible to long-term morbidities and mortality the longer they go without treatment, or even with inaccurate treatment for bloodstream infections or sepsis,” said presenting study author April Aralar, Ph.D., a postdoctoral scholar at the University of California, San Diego. “Therefore, we felt that it was of the utmost importance to be able to have a diagnostic that could work with what was available for neonates: that is, a small amount of blood, a small amount of bacteria, and a small amount of time to get the diagnosis.”

In the new study, researchers set out to test a novel technology called u-dHRM (Universal Digital High-Resolution Melt) using pediatric blood samples from Rady Children's Hospital in San Diego. Researchers took 17 blood samples that were already tested using blood ctulreu, the clinical standard diagnostic test, and subsequently tested the blood with the new platform.

The researchers found 100% agreement between the novel method and the clinical gold standard of blood culture, and the new technology delivered the results much faster. “Our test only took 6 hours from start to finish, whereas blood culture takes anywhere from 15 hours to 5 days to get a result,”  Aralar said.

Aralar said the findings are encouraging and that the method may be a new way of quickly and accurately diagnosing bloodstream infections in newborns. It could additionally be applied to children and adults.

“Next we hope to do a prospective clinical trial across multiple clinical centers and hospitals to test our method across more patients and different populations. Hopefully we can deploy this technology to more hospitals and have point of care diagnostics for babies and children more widely,”  Aralar said.

Ex vivo gene editing and cell therapy for hereditary tyrosinemia type 1

2024-06-14
Background: We previously demonstrated the successful use of in vivo CRISPR gene editing to delete 4-hydroxyphenylpyruvate dioxygenase (HPD) to rescue mice deficient in fumarylacetoacetate hydrolase (FAH), a disorder known as hereditary tyrosinemia type 1 (HT1). The aim of this study was to develop an ex vivo gene-editing protocol and apply it as a cell therapy for HT1. Methods: We isolated hepatocytes from wild-type (C57BL/6J) and Fah-/- mice and then used an optimized electroporation protocol to deliver Hpd-targeting CRISPR-Cas9 ribonucleoproteins into hepatocytes. Next, hepatocytes were transiently incubated in ...

Intranasal COVID-19 vaccine headed to clinical trials

Intranasal COVID-19 vaccine headed to clinical trials
2024-06-14
University of Georgia-based startup CyanVac LLC received federal funding to support a comparative Phase 2b clinical trial of CVXGA, the company’s intranasal vaccine candidates designed to protect against COVID-19. As part of the award from Project NextGen, a federal initiative based in the U.S. Department of Health and Human Services (HHS), CyanVac will sponsor a randomized, double-blind Phase 2b study with 10,000 participants to compare the efficacy and safety of the intranasal vaccine against an FDA-approved mRNA-based COVID-19 vaccine. The new vaccine is based on a viral delivery platform developed by He containing modified ...

High out-of-pocket costs may be barrier to filling naloxone prescriptions, study shows

2024-06-14
Patients are less likely to fill prescriptions for naloxone when they face increases in out-of-pocket costs, according to U-M researchers. Patients are less likely to fill prescriptions for naloxone when they face increases in out-of-pocket costs, according to research by the University of Michigan. Published in the Journal of the American Medical Association, the study utilized data from a national pharmacy transactions database from November 2020 to March 2021. Researchers found that about 1 in 3 naloxone ...

Sharks have depleted functional diversity compared to the last 66 million years

2024-06-14
New research by Swansea University and the University of Zurich has found that sharks retained high levels of functional diversity for most of the last 66 million years, before steadily declining over the last 10 million years to its lowest value in the present day. Modern sharks are among the ocean’s most threatened species; yet have notably survived numerous environmental changes in their 250-million-year history. Today, their more than 500 species play many different ecological roles, from apex predators to nutrient transporters. Ecological roles are determined by species’ traits such as body size, ...

Fasting primes the immune system’s natural killer cells to better fight cancer, new study in mice finds

Fasting primes the immune system’s natural killer cells to better fight cancer, new study in mice finds
2024-06-14
Periods of fasting reprogram the immune system’s natural killer cells to better fight cancer, according to a new study in mice from researchers at Memorial Sloan Kettering Cancer Center (MSK). Fasting and other dietary regimens are increasingly being explored as ways to starve cancer cells of the nutrients they need to grow and to make cancer treatments more effective. Now a team of researchers from MSK’s Sloan Kettering Institute and their collaborators have shown for the ...

Are patient partners a necessity in research?

2024-06-14
Sjögren’s disease is a systemic autoimmune disorder that often causes sicca symptoms – or dryness of the eyes and mouth, alongside many other complications such as fatigue, pain, and neurological manifestations. There are treatments that help with symptoms, but none that address the underlying disease processes.3 One key issue in developing new treatments is that Sjögren’s can differ from person to person – and that makes it hard to measure and compare outcomes in a clinical trial.   NECESSITY is an interventional trial looking at new clinical endpoints in Sjögren’s disease. ...

Encouraging cooperation in inflammatory arthritis

2024-06-14
Inflammatory arthritis describes a group of diseases caused by an overactive immune system. The different types of inflammatory arthritis include rheumatoid arthritis, psoriatic arthritis, juvenile idiopathic arthritis, and ankylosing spondylitis. The most common symptoms are joint pain and stiffness. Pain is the predominant symptom in the majority of people with inflammatory arthritis, which contributes to the global burden of rheumatic and musculoskeletal conditions.1 Knowledgeable support can reduce ...

Protection against disease and treatment toxicity

2024-06-14
Autologous hematopoietic stem cell transplantation (aHSCT) for SSc has been proven the most effective treatment strategy with regard to overall and event free survival in selected patients.2 But a key limitation is its toxicity, and new treatment options are needed. Two abstracts presented at the 2024 EULAR congress in Vienna focused on novel approaches.   Jörg Henes presented on behalf of the AST MOMA investigators. This prospective, open-label, study evaluated the feasibility of aHSCT in patients with impaired lung or heart function, and also ...

Does BMO induced by mechanical stress progress to structural lesions?

2024-06-14
BMO in the sacroiliac joint on MRI is present in up to 84% of people with non-radiographic axSpA – but it is also often seen in a non-inflammatory setting, such as in women after childbirth.1,2 As back pain is common after childbirth, differential diagnosis with axSpA is an important issue in clinical practice.1 In axSpA, active inflammatory lesions are likely to progress to structural lesions over time – particularly fat lesions and erosions. But it is not known whether the same is true for BMO induced by mechanical stress. In June 2024, EULAR – The European Alliance of Associations for Rheumatology – held its annual congress ...

Is fish intake linked to JIA?

2024-06-14
In 2019, a Swedish prospective birth cohort study of over 15,000 children showed that consuming fish at least once a week during pregnancy and during the first year of life was associated with up to a 5-fold increased risk of JIA, compared to those with fish consumption less than once a week. This increased risk was primarily attributed to elevated exposure to heavy metals.1 Now, new research shared at the 2024 congress of EULAR – The European Alliance of Associations for Rheumatology – is investigating ...
