Imaging physicians in Iran used the social media program WhatsApp to develop a smartphone-based solution to help address health care service needs in the coronavirus pandemic, according to a study in the Journal of the American College of Radiology. "Our humanitarian teleconsultation strategy allows [for] reliable triage of COVID-19 infection using radiology experts from centers from around the world to provide consultation in regions with limited access to thoracic radiology expertise during a rapidly growing epidemic," lead study author Dr. Amir Davarpanah wrote.
Researchers found that CT scans of people with COVID-19 ages 45 and older had more severe lung and lung lobe involvement, as well as more lesions, which were found with air bronchograms more often, compared with CT scans from those younger than 18. The findings, published in the European Journal of Radiology, "are likely to help with understanding and evaluating the condition of infected patients of different ages, and provide insight into the possible subsequent evolution of the disease in infected patients of different ages, which should facilitate more accurate diagnosis and the development of treatment strategies," researchers wrote.
Researchers analyzed CT and X-ray images and reverse transcription polymerase chain reaction test results of 33 newborns from mothers with COVID-19 pneumonia and found that three of the babies were diagnosed with the infection. The findings, published in JAMA Pediatrics, highlighted the importance of screening pregnant women and implementing strict infection control strategies, close monitoring of newborns at risk for the illness and quarantining infected mothers, study authors wrote.
A study in PLOS ONE found that using chest X-ray with lung ultrasound is a viable alternative to diagnose and manage pneumonia in children, despite a better performance in some metrics observed in using MRI alone. The findings, based on 33 children with pneumonia, showed that "in cases where lung ultrasound cannot be realized or the combination of chest X-ray and lung ultrasound might not be sufficient, MRI, as a radiation-free modality, should be preferred to CT," lead study author Dr. Philip Konietzke wrote.
President Donald Trump sent a letter to US governors telling them that the administration is developing new criteria that would classify US counties into low-, medium- or high-risk "with respect to continued risks posed by" the emerging coronavirus. Trump said the categories will be accompanied with new guidelines that can be used by local and state policymakers on whether to retain, increase or decrease their social distancing guidelines and other coronavirus mitigation efforts.
Researchers who used a novel imaging method called optical photothermal spectroscopy found that mouse models of early-stage Alzheimer's disease had varying structural changes in nerve cell proteins depending on the location within the cell. The approach, described in Advanced Science, sheds light on the initial neuron molecular changes in Alzheimer's and may be used in studying other neurodegenerative diseases, such as frontal lobe and Lewy body dementia, as well as Parkinson's disease, researchers said.
Individuals with Parkinson's disease and dementia who received IRLAB Therapeutics' IRL752, a new small-molecule drug, had significantly reduced cognitive impairment, axial motor symptoms and apathy, compared with those who were given placebo, researchers reported in the journal Movement Disorders. The findings, based on Phase IIa clinical trial data, also showed that IRL752 intake resulted in mostly mild adverse events and achieved blood concentrations indicating therapeutic effect, suggesting its efficacy in people with Parkinson's dementia.
A fixed-rate notes offering is expected to bring in $1.1 billion for Royal Philips, to be used for sustainable innovation expenses and other company needs.
Critical care physician Daniela Lamas says she has concerns over tightened protocols preventing visitors in the ICU, as her patients now have to face serious illness alone. She hopes to find ways to maintain connection such as phone calls, and iPads at the bedside, to prevent the overwhelming isolation that may lead to post traumatic stress in survivors of COVID-19, but also acknowledges that physicians are more pressed for time than ever.
Maryland social workers Arlen Grad Gaines and Meredith Englander Polsky have written an e-book called "I Have a Question About Coronavirus," the fourth entry in their "I Have a Question" series. The book, distributed for free, aims to help parents start conversations with their children about the virus and provide support.
