Response: Staphylococcus aureus commonly causes infections in ICUs. One approach to preventing these infections is using nasal mupirocin plus chlorhexidine gluconate (CHG) bathing for ICU patients. This practice is known to prevent methicillin-resistant Staphylococcus aureus (MRSA) infections and all-cause. bloodstream infections.  This practice has been broadly adopted in ICUs in the US, but adoption of mupirocin as a universal topical antibiotic has been slowed by concerns for engendering mupirocin resistance. This cluster-randomized trial in adult ICUs was conducted to assess whether universal nasal antiseptic povidone-iodine (iodophor), to which minimal S. aureus resistance is expected, was an acceptable alternative to universal nasal mupirocin for reducing S. aureus and MRSA clinical cultures in the setting of daily CHG bathing. Those who received chlorhexidine (CHG) bathing with mupirocin had an 18% reduction in risk of Staphylococcus aureus clinical cultures and a 15% reduction in risk of methicillin-resistant S. aureus (MRSA) clinical cultures compared to patients who received CHG bathing with intranasal iodophor.  These results show that using mupirocin for nasal decolonization may be preferred over iodophor because it is more effective at preventing S. aureus infections.

Response: More than 192 million people ages 12 years and older in the U.S. received at least one dose of mRNA COVID-19 vaccines from December 2020 through August 2021. From this population, VAERS (the Vaccine Adverse Event Reporting System) received 1,991 reports of myocarditis,  1,626 of which met the case definition of myocarditis. Rates of myocarditis were highest following the second dose of an mRNA vaccine among males aged 12–15 years (70.7 per million doses of Pfizer), 16-17 years (105.9 per million doses of Pfizer), and 18–47 years (52.4 and 56.3 per million doses of Pfizer and Moderna, respectively). Of those with myocarditis, the median age was 21 years and the median time from vaccination to symptom onset was two days. Males accounted for 82% of patients for whom sex was known. Approximately 96% were hospitalized, 87% of whose symptoms had gone away by the time they were discharged from the hospital. Non-steroidal anti-inflammatory drugs (589/676, 87%) were the most common treatment.

Response: Psychological stress has been linked to increased risk for cardiovascular disease. The mechanisms have not been clear. One hypothesis has been that chronic or repeated exposure to psychological stress can cause a phenomenon of “wear-and-tear” of the vascular system due to activation of the neuroendocrine stress systems, eventually leading to accelerated plaque formation and adverse cardiovascular events. However, this has never been demonstrated in humans. In some individuals, psychological stress can induce a transitory impairment of the endothelium, a phenomenon known as endothelial dysfunction. A healthy endothelium is essential in blood flow regulation and in maintaining cardiovascular health.

 A retraction and replacement have been issued due to a major coding error that resulted in the reporting of incorrect data in this study surrounding the difference in transplant rates between for-profit and non-profit dialysis centers. Please see link below:

Response: We know that historically, for-profit dialysis facilities have been shown to have lower rates of kidney transplantation than patients who receive treatment in non-profit dialysis facilities. However, these studies are outdated, and did not examine access to living donor transplantation or include the entirety of the end-stage kidney disease population

MedicalResearch.com Interview with: Jean A. Welsh, RN, MPH, PhD Departments of Epidemiology and Pediatrics Emory University Wellness Department, Children’s Healthcare of Atlanta Atlanta, Georgia MedicalResearch.com: What is the background for this study? Response: As the evidence has accumulated regarding the health risks associated with sugar-sweetened beverages, I’ve wondered about fruit juices.  Though they have a kind of healthy halo, their main ingredients are the same as sugar-sweetened beverages, sugar and water.  We know that young children drink a lot of fruit juice, and I’ve wondered if older children and adults might switch to drinking more as concern grows about soft drinks and other sugar-sweetened beverages.

What are the main findings?  Response: Firearm injury is a leading cause of injury and death in the United States. Many physician groups advocate for evidence-based policies, such as universal background checks, to reduce this morbidity and mortality. We studied contributions of the 25 largest political action committees (PACs) affiliated with physician professional groups during the 2016 election cycle and found that almost all gave more money to political candidates who voted against universal background checks and were endorsed by the NRA. These PACs contributed to more than twice as many incumbent US Senate candidates who voted against an amendment to expand firearm background checks than those who voted for the amendment. In the US House of Representatives, the pattern of giving was similar. These PACs gave $2.8 million more to candidates who did not sponsor a bill to expand background checks than to those who did. Finally, these physician PACs were more than twice as likely to contribute to and gave almost $1.5 million dollars more to candidates rated A by the NRA.
