The findings were published in journal <em>Nature Machine Intelligence.</em></p><p>The technique, developed by researchers from the University of Cambridge and the Huazhong University of Science and Technology, utilized a method called federated learning to develop their model.</p><p>Since the beginning of the COVID pandemic, AI researchers have strived to construct models that could diagnose the disease. However, many of these models were built using low-quality data, as highlighted by the researchers. &ldquo;AI has a lot of limitations when it comes to COVID-19 diagnosis, and we need to carefully screen and curate the data so that we end up with a model that works and is trustworthy,&rdquo; said co-first author Hanchen Wang from Cambridge&rsquo;s Department of Engineering via a <a href="https://www.eurekalert.org/news-releases/938224">press release</a>. &ldquo;Where earlier models have relied on arbitrary open-sourced data, we worked with a large team of radiologists from the NHS and Wuhan Tongji Hospital Group to select the data, so that we were starting from a strong position.&rdquo;</p><h2><a href="https://www.docwirenews.com/home-page-editor-picks/converting-hotels-to-rooms-for-homeless-people-curbed-covids-spread/">Converting Hotels to Rooms for Homeless People Curbed COVID&rsquo;s Spread</a></h2><p>Here&rsquo;s a social distancing strategy that really worked in the early days of the pandemic: New research shows that providing hotel rooms to homeless people at high risk for severe COVID-19 significantly lowered their chance of infection.</p><p>In early April 2020, the city of Chicago made 200 rooms at a hotel available to homeless people in shelters who were considered at high risk because they were: at least 60; at least 55 with any underlying health condition; or younger than 55 years with HIV/AIDS or any other health condition known to substantially increase COVID-19 risk.</p><p>The participants also received extensive health and social support services, and could stay as long as desired during the five months that the rooms were available.</p><p>&ldquo;We saw that people in this intervention were 2.5 times less likely to contract the virus compared to rates among people experiencing&nbsp;<a class="rm-stats-tracked" href="https://nationalhomeless.org/about-homelessness/" target="_blank" rel="noopener">homelessness</a>&nbsp;in shelters across the city,&rdquo; said study co-author Dr. Elizabeth Tung. She is an assistant professor of medicine at University of Chicago Medicine.</p><h2><a href="https://www.docwirenews.com/latest-nephrology-news/nursing-solutions-for-covid-19-related-aki/">Nursing Solutions for COVID-19-Related AKI</a></h2><p>Patients who develop acute kidney injury (AKI) during SARS-CoV-2 infection face increased risk of morbidity and mortality. AKI can occur at any stage of infection with <a href="https://www.docwirenews.com/nephtimes/nephtimes-diseases-and-conditions/covid-19-nephtimes-diseases-and-conditions/diabetic-nephropathy-and-obesity-influence-covid-19-outcomes/">COVID-19</a>; clinical judgment and awareness of AKI risk factors in combination with early detection and diagnosis are key in preventing short- and long-term complications in patients with AKI related to COVID-19.</p><h2><a href="https://www.docwirenews.com/home-page-editor-picks/british-studies-show-vaccines-weaken-against-omicron-but-boosters-help/">British Studies Show Vaccines Weaken Against Omicron, But Boosters Help</a></h2><p>The ability of two-dose COVID-19 vaccines to protect against symptomatic infection by the Omicron variant falls significantly short, but a booster shot provides considerable protection, according to the<a class="rm-stats-tracked" href="https://khub.net/documents/135939561/430986542/Effectiveness+of+COVID-19+vaccines+against+Omicron+variant+of+concern.pdf/f423c9f4-91cb-0274-c8c5-70e8fad50074" target="_blank" rel="noopener">&nbsp;first real-world study</a>&nbsp;of how effective vaccines are against the rapidly spreading new form of the coronavirus.</p><p>Four months after their second dose of the Pfizer-BioNTech vaccine, people had only about 35% protection against symptomatic infection by Omicron, which is significantly lower than against the Delta variant, British government scientists said.</p></h2>
