From knee replacement to spine surgery, your next procedure likely will be outpatient
With nearly 50 million outpatient surgeries performed in the U.S. each year and the increasingly complex nature of the procedures, patients need to know several important details when having surgery without an overnight stay in the hospital, says the American Society of Anesthesiologists (ASA). Updated fasting restrictions, removing jewelry to reduce the risk of burns and asking about regional blocks for non-opioid pain control when undergoing anesthesia are a few important factors that could lead to increased satisfaction and safer outcomes.

FAU Emergency Medicine Resident Physicians Train for Coronavirus Contagion
With seven reported cases in Florida to-date, FAU emergency medicine resident physicians prepared for the threat of a coronavirus contagion using a simulated or “mock” disaster scenario at FORTS Medical. The simulation involved a cruise ship dock-setting scenario and mock passengers were transported by bus. The passengers stormed into the large warehouse to challenge the resident physicians to react and respond quickly to triage the patients. About 100 people participated in the half-day simulation including local nurses, paramedics, and student and community actors.

Improving detection of prenatal alcohol exposure using complementary tools
Drinking while pregnant can harm the developing fetus, leading to physical, cognitive, and neurobehavioral effects that may persist into adulthood. No safe level of alcohol in pregnancy has been identified, and many guidelines now recommend total abstinence. However, prenatal drinking remains common, particularly early on before women are aware of their pregnancy.
New Legislation Would Jeopardize Patient Access to Medical Tests Across the Board by Restricting Policy that Removed Barriers to Coronavirus Testing
On March 5, U.S. House and Senate lawmakers introduced the VALID Act, which would give the Food and Drug Administration (FDA) new, expansive powers to regulate laboratory developed tests—tests that are already regulated by the Centers for Medicare and Medicaid Services (CMS) and are subject to stringent personnel, quality control, and proficiency testing requirements. This bill promotes duplicative, costly federal regulations for clinical laboratories that will result in decreased patient access to essential medical tests. AACC urges Congress not to act on this bill until its impact on healthcare can be thoroughly evaluated.
Millions of US workers at risk of infections on the job, UW researchers calculate, emphasizing need to protect against COVID-19
A University of Washington researcher calculates that 14.4 million workers face exposure to infection once a week and 26.7 million at least once a month in the workplace, pointing to an important population needing protection as the novel coronavirus disease, COVID-19, continues to break out across the U.S.

Don’t blame the messenger — unless it’s all stats and no story
In some cases of ineffective messaging, it might be appropriate, despite the aphorism to the contrary, to blame the messenger.
“Our findings suggest that telling stories when communicating can make the speaker appear more warm and trustworthy, as opposed to speaking some other way, such as providing only statistics and figures,” says UB researcher.
FSU professors available to comment on economic impact of coronavirus
As the coronavirus disease 2019 —or COVID-19— continues to spread, it disrupts world markets, supply chains and entire economies. As of March 5, nearly 100,000 people were confirmed infected and more than 3,000 deaths attributed to the disease.The spread of coronavirus continues to create instability on a global scale.

Study: Cough That Spreads Tuberculosis Has Pain-Linked Trigger
University of Texas System researchers have pinpointed a molecule that the tuberculosis bacterium manufactures to induce the coughing that spreads the disease by triggering a pain-receptor response. Their findings illustrate that the disease’s spread might be prevented by halting production of sulfolipid-1.

A Bite Out of Apple: What Happens If You Lose Strategic Talent?
When Apple’s longtime design guru Jony Ive announced that he’d be starting his own agency, it meant major change. The situation serves as a case in point for any organization whose success rests on strategic human capital: If strategy is intrinsically tied to talent, how does a firm support that talent or proceed if that talent disengages?
Using new genomic technology, UCI researchers discover breast cancer cells shift their metabolic strategy in order to metastasize
New discovery in breast cancer could lead to better strategies for preventing the spread of cancer cells to other organs in the body, effectively reducing mortality in breast cancer patients.
According to a study, published today in Nature Cell Biology, breast cancer cells shift their metabolic strategy in order to metastasize. Instead of cycling sugar (glucose) for energy, they preferentially use mitochondrial metabolism.
