A study in Radiology found that combining a content-based image retrieval search engine with a deep learning algorithm to interpret CT exam images from patients with interstitial lung disease yielded an overall diagnostic accuracy of 60.9%, compared with 46.1% among radiologist readers. "This system can be expected to provide radiologic decision support to centers where thoracic imaging expertise is unavailable or cases of ILD are scarce," researchers wrote.
Researchers evaluated patients with heart failure with preserved ejection fraction and found that those who showed higher blood-flow defect levels on iodine-123 metaiodobenzylguanidine SPECT scan images were at an increased risk of dying from cardiac events, compared with those who had low blood-flow defect levels. "These results indicate that obtaining I-123 MIBG-SPECT analysis would provide additive prognostic value in patients with HFpEF," study authors wrote in JACC: Cardiovascular Imaging.
Compared with MRI alone, PET/MRI with gallium-68 PSMA-11 was found to be better at detecting recurrent prostate cancer, according to a study published in Translational Oncology. "Combined utility with PSMA PET/MRI is a powerful tool which can aid in not only the detection of disease, but also guide in treatment planning for prostate cancer patients," researchers wrote.
As hospitals have become crowded with COVID-19 patients, nearly 1 in 5 Americans have had to delay health care for serious illnesses, a study by the Robert Wood Johnson Foundation and the Harvard T.H. Chan School of Public Health found. Many patients say they are seeing negative outcomes as a result, and clinicians have reported issues like cancers being diagnosed at a later stage.
Unvaccinated people are 11 times more likely to die from COVID-19 than people who are fully vaccinated against the disease, and those who have not been vaccinated are six times more likely to test positive, according to a CDC analysis. The report documented 665 cases per 100,000 unvaccinated people as of as of Aug. 29, while there were 150 cases per 100,000 of those who had received the Johnson & Johnson vaccine, 125 per 100,000 among those who received the Pfizer/BioNTech vaccine, and 86 per 100,000 of those who received Moderna's vaccine.
The number of messages physicians at ambulatory care clinics receive rose between March 2020 and June 2021, with physicians in surgical specialties experiencing the steepest rise, potentially due to a backlog of elective procedures to be cleared, according to a research letter in JAMA Network Open. The average number of patient requests for medical advice rose for primary care, medical and surgical physicians, while the number of patient calls also rose, and researchers warned about the growing burden on physicians.
The National Health Service Corps will receive $100 million from the American Rescue Plan to address the shortage of health care workers, according to the Biden administration. The funding will help recruit primary care doctors in places challenged by recruitment and retention issues. "This investment will make a tremendous impact on access to primary care and addressing health disparities at a critical time," said Diana Espinosa, acting administrator of the Health Resources and Services Administration.
The Biden administration is shifting oversight of the government's pandemic data tracking system from HHS' Office of the Chief Information Officer back to the CDC amid scrutiny over the government's handling of public health data infrastructure, according to documents obtained by Bloomberg. The public health tracking system, called HHS Protect, collects information from over 6,000 hospitals on COVID-19 cases and vaccination rates as well as use of ICU beds, personal protective equipment, COVID-19 tests and therapeutics.
Artificial intelligence tools yielded an area under the curve score of 0.77 in predicting the severity of chronic obstructive pulmonary disease among patients who underwent pulmonary function testing and a noncontract CT scan, compared with 0.76 among thoracic radiologists, according to a study in Academic Radiology. "Performance of the assessed AI prototypes was similar to radiologists' subjective assessment," researchers wrote.
