Sepsis can cause dangerously low blood pressure, which is typically treated with intravenous (IV) fluids and/or a vasopressor, a drug that causes constriction of the blood vessels. Whether treatment of sepsis-induced low pressure should primarily be treated with IV fluids or vasopressors has been debated for decades with no clear answer.
Researchers at University of California San Diego and UC Riverside have further elucidated the molecular pathway used by the SARS-CoV-2 virus to infect human lung cells, identifying a key host-cell player that may prove a new and enduring therapeutic target for treating COVID-19.

New UCLA-led research suggests that antiretroviral drugs called TAF and TDF directly reduce energy production by mitochondria, structures inside cells that generate the power that cells use to function. Both drugs led to reduced cellular oxygen consumption rates, a measure of the ability of the mitochondria to produce energy, compared with controls.

The researchers screened a library of drugs using a mouse endothelial cell line to identify pathways that are involved in the regulation of Robo4 and found that two competitive SMAD signaling pathways appear to regulate Robo4 expression. When the researchers treated LPS-injected mice with a drug that inhibits ALK1-SMAD signaling, they observed increased Robo4 expression, decreased vascular permeability, and reduced mortality.
High levels of mucosal IgA antibodies in the airways protect against SARS-CoV-2 infection for at least eight months. Omicron infection generates durable mucosal antibodies, reducing the risk of re-infection.
Nonpharmaceutical interventions slowed the spread of COVID-19 and other infectious diseases but now, as NPIs are lifted, countries are seeing a resurgence in several respiratory diseases. In Chaos, scientists, using data from Hong Kong to develop their model, describe a threshold control method that can be used to predict the best time to lift NPIs without overwhelming the hospital systems when these other respiratory diseases inevitably surge back. They found that reintroducing NPI measures when a threshold of 600 severe cases is reached could ensure that the hospital system in Hong Kong is not overwhelmed by severely infected patients.

Results of the 18-month study, published in Lancet Regional Health - Americas and led by Amit Bahl, M.D., M.P.H., emergency medicine with Corewell Health East, formerly Beaumont Health, showed that while omicron cases had the highest hospital admission rates among children ages 0 to 17, serious, even deadly, cases of illness were less likely during omicron than during the delta and alpha variants. In fact, the odds of severe disease were 65% lower during omicron compared to alpha.
