(Press-News.org) Honolulu, HI | April 18, 2023—Findings from an award-winning Scientific Online Poster presented during the 2023 ARRS Annual Meeting on the island of Oahu determined that assessing the vascularity and elastography in suspect TIRADS categories can efficiently diagnose malignancy of thyroid nodules.
Acknowledging that sonographic TIRADS scoring remains the first method of imaging assessment for diagnosing malignant thyroid nodules, “we assessed the added value of shear-wave elastography (SWE) to classic TIRADS assessment,” said Leila Aghaghazvini, MD, from the department of radiology at Shariati Hospital and Iran’s University of Medical Sciences in Tehran.
In this ARRS Annual Meeting Cum Laude award-winning Online Poster, 200 total thyroid nodules were assessed by conventional sonography to ascertain TIRADS score and pertinent descriptors. Using a 7.5 MHz probe to asses vascularity pattern and resistive index (RI), elastography evaluations were performed quantitatively via color mapping and calculating mean and maximum velocities in shear-wave modality. Final diagnoses of all thyroid nodules were confirmed by histopathology assessment or follow-up imaging.
According to Aghaghazvini et al., patient mean age was 53 years; 105 were men [52.5%]. And of 27 [13.5%] total nodules with malignancy in their study, 14 [7%] were papillary thyroid carcinoma, 11 [5.5%] were follicular thyroid carcinoma, and 2 [1%] were medullary thyroid cancer. AUC of the ROC curve for TIRADS assessment was 0.76. Results found 37 [18.5%] TIRADS 4 nodules, wherein 15 [40.5%] were malignant, and 57 [28.5%] TIRADS 5 nodules, 12 [21.1%] of which were malignant.
In only TIRADS 4 nodules, Doppler grade AUC, RI, color map elastography grade, SWE maximum velocity, and mean SWE velocity for diagnosing malignancy were 0.8, 0.93, 0.89, 0.86, and 0.82, respectively. Meanwhile, profiles in TIRADS 5-only nodules were 0.8, 0.96, 0.85, 0.96, and 0.97, respectively. Additionally, in TIRADS 4, an RI cutoff point of 0.6 yielded diagnostic efficacy indices of 0.93, 1, 0.97, 1, and 0.96 for sensitivity, specificity, efficiency, PPV and NPV, respectively. In TIRADS 5 nodules, a cutoff point of 4.33 for SWE mean velocity yielded diagnostic efficacy indices of 1, 0.82, 0.86, 0.6, and 1 for sensitivity, specificity, efficiency, PPV and NPV, respectively.
North America’s first radiological society, the American Roentgen Ray Society (ARRS) remains dedicated to the advancement of medicine through the profession of medical imaging and its allied sciences.

Update on the analysis method to estimate the greenhouse gas concentrations from GOSAT
2023-04-18
1. Background and objectives
The Greenhouse gases Observing SATellite (GOSAT) that is the joint mission of the Ministry of Environment, the National Institute for Environmental Studies (NIES), and the Japan Aerospace Exploration Agency has observed almost continuously since its launch and is currently in operation.
Thermal And Near-infrared Sensor for carbon Observation – Fourier Transform Spectrometer (TANSO-FTS) onboard GOSAT observes the shortwave infrared (SWIR) spectra(*1). The carbon dioxide (CO2) and methane (CH4) concentrations can be estimated by ...
Healthcare epidemiologists and infectious diseases experts review changing context for masking in healthcare settings
2023-04-18
The time has come and gone for universal masking in healthcare settings, according to healthcare epidemiologists and infectious diseases experts from healthcare systems throughout Boston and beyond. In a commentary published in Annals of Internal Medicine and co-authored by experts from Mass General Brigham, Beth Israel Lahey Health, Tufts Medicine, the VA Healthcare System Boston, and other healthcare systems across the country, the authors describe the changing context and conditions of the pandemic and outline why universal masking should no longer be required in healthcare settings.

Cardiac arrest in hospital: survival a matter of resources
2023-04-18
Hospital inpatients have better prospects of surviving a cardiac arrest in large hospitals and well-resourced wards, and daytime cardiac arrests are also associated with better chances of survival, a University of Gothenburg thesis shows.
Cardiac arrest means that the heart stops pumping blood. Within seconds, unconsciousness occurs; within minutes, brain cells start dying, causing irreparable damage.
The key to enhancing the patients’ chances of survival is restoring the circulation of oxygenated blood in the body. ...
Early study - faecal transplant to help slow early-stage motor neuron disease progression
2023-04-18
A randomised clinical trial is looking at whether faecal microbiota transplantation (FMT) from healthy donors into adults with early-stage amyotrophic lateral sclerosis (ALS – one of the most common forms of motor neurone disease) can modulate the immune reaction during inflammation responses that characterise disease progression, and aims to investigate the relationship between specific gut bacteria and their action on immune system cells.
The preliminary findings by Dr Alessandra Guarnaccia from Columbus-Gemelli University Hospital IRCCS, Rome, Italy and ...
Preventing a measles outbreak: steps taken by London hospital to protect patients and staff potentially exposed to the virus
2023-04-18
The steps taken by a London hospital to prevent an outbreak of measles will be detailed at this year’s European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) in Copenhagen, Denmark (15-18 April).
Measles, which is highly contagious, can cause serious and potentially life-threating illness and complications including blindness, encephalitis (swelling of the brain) and pneumonia. Pregnant women, infants and severely immunocompromised individuals are at highest risk.
Contracted when pregnant, it can cause low birth weight babies, premature birth, miscarriage or stillbirth.
It usually starts with cold-like symptoms, followed by a rash a few days later. ...
AI software at least as good as radiologists at detecting TB from chest X-rays
2023-04-18
AI software can accurately detect TB from chest X-rays, a study being presented at this year’s European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) in Copenhagen, Denmark, (15-18 April), shows.
Tuberculosis (TB) is a major cause of death and disease worldwide. It causes 1.6 million deaths a year, making it is the 13th leading cause of death globally and the second biggest infectious killer, after COVID-19.
In low-resource settings, chest X-rays play an important role in the diagnosis of patients ...

Using machine learning to find reliable and low-cost solar cells
2023-04-18
Researchers at the University of California, Davis College of Engineering are using machine learning to identify new materials for high-efficiency solar cells. Using high-throughput experiments and machine learning-based algorithms, they have found it is possible to forecast the materials’ dynamic behavior with very high accuracy, without the need to perform as many experiments.
The work is featured on the cover of the April issue of ACS Energy Letters.

Resident T-cells key to salmonella immunity
2023-04-18
Salmonella infections cause about a million deaths a year worldwide, and there is an urgent need for better vaccines for both typhoid fever and non-typhoidal Salmonella disease. New work from researchers at the UC Davis School of Veterinary Medicine shows how memory T cells, crucial for a vaccine that induces a powerful immune response, can be recruited into the liver in a mouse model of Salmonella.
The work was published April 11 in Proceedings of the National Academy of Sciences.
“Understanding the immunology is key to developing a better vaccine,” said Professor Stephen McSorley, ...
