Objective: To assess the effects of the 2020 United States Public Health Service (PHS) "Increased Risk" Guidelines update.
Background: Donors labeled as "Increased Risk" for transmission of infectious diseases have been found to have decreased organ utilization rates despite no significant impact on recipient survival. Recently, the PHS provided an updated guideline focused on "Increased Risk" organ donors, which included the removal of the "Increased Risk" label and the elimination of the separate informed consent form, although the actual increased risk status of donors is still ultimately transmitted to transplant physicians. We sought to analyze the effect of this update on organ utilization rates.
Methods: This was a retrospective analysis of the Organ Procurement and Transplantation Network database which compared donor organ utilization in the 2 years before the June 2020 PHS Guideline update for increased-risk donor organs (June 2018-May 2020) versus the 2 years after the update (August 2020-July 2022). The organ utilization rate for each donor was determined by dividing the number of organs transplanted by the total number of organs available for procurement. Student test and multivariable logistic regression models were used for analysis.
Results: There were 17,272 donors in the preupdate cohort and 17,922 donors in the postupdate cohort; of these, 4,977 (28.8%) and 3,893 (21.7%) donors were considered "Increased Risk", respectively. There was a 2% decrease in overall organ utilization rates after the update, driven by a 3% decrease in liver utilization rates and a 2% decrease in lung utilization rates. After multivariable adjustment, donors in the postupdate cohort had 10% decreased odds of having all organs transplanted.
Conclusions: The 2020 PHS "Increased Risk" Donor Guideline update was not associated with an increase in organ utilization rates in the first 2 years after its implementation, despite a decrease in the proportion of donors considered to be at higher risk. Further efforts to educate the community on the safe usage of high-risk organs are needed and may increase organ utilization.

The recent emergence of bile salt hydrolase (BSH) enzyme as a therapeutic target reflects its unbound potential in mitigating hypercholesterolemia, obesity, and gastrointestinal issues. However, to bolster its industrial application, optimization of BSH assay lays the cornerstone for enhancing sensitivity, specificity, and reproducibility. The current study delved into optimizing the BSH assay parameters utilizing response surface methodology (RSM) and one-factor-at-a-time (OFAT) method for two novel, natural BSH producers, Heyndrickxia coagulans ATCC 7050 and Lactiplantibacillus plantarum ATCC 10012.

Copper (Cu), a trace element with redox activity, is both essential and toxic to living organisms. Its redox properties make it a cofactor for a variety of proteins, but it also causes oxidative stress, hence the need to maintain intracellular copper homeostasis. However, the role of copper in the regulation of antioxidant defense in bacteria remains unclear, and the involved transcription factors remain to be explored.

Perfluorooctane sulfonate (PFOS) and its new substitute, perfluorobutane sulfonate (PFBS), are increasing in concentration in the environment annually, and their toxicity cannot be ignored. With an increasing amount of PFOS and PFBS entering the environment, especially into farmland soil, it is very likely to pollute tobacco-planting soil. Therefore, we chose tobacco (Nicotiana tabacum L.
