AI Article Synopsis
- Standard operating rooms (SOR) are often thought to be the safest for tissue procurement, but using non-operating dedicated rooms (NODR) or even ICU might be more efficient and less costly when no organ retrieval occurs.
- The study analyzed tissue retrieval data from 2,535 deceased donors to assess the risk of microbial contamination based on different locations (ICU, SOR, NODR).
- Results indicated that retrieval in NODR had a significantly lower risk of contamination, suggesting that using dedicated rooms or ICU for tissue procurement could reduce contamination rates and might eliminate the need to transfer patients from ICU to SOR.
Article Abstract
Background: Standard operating rooms (SOR) are assumed to be the best place to prevent microbial contamination when performing tissue procurement. However, mobilizing an operating room is time and cost consuming if no organ retrieval is performed. In such case, non-operating dedicated rooms (NODR) are usually recommended by European guidelines for tissue harvesting. Performing the tissue retrieval in the Intensive care unit (ICU) when possible might be considered as it allows a faster and simpler procedure.
Objective: Our primary objective was to study the relationship between the risk of microbial contamination and the location (ICU, SOR or NODR) of the tissue retrieval in heart-beating and non-heart-beating deceased donors.
Materials And Method: We retrospectively reviewed all deceased donors' files of the local tissue banks of Montpellier and Marseille from January 2007 to December 2014. The primary endpoint was the microbial contamination of the grafts. We built a multivariate regression model and used a GEE (generalized estimating equations) allowing us to take into account the clustered structure of our data.
Results: 2535 cases were analyzed involving 1027 donors. The retrieval took place for 1189 in a SOR, for 996 in a hospital mortuary (NODR) and for 350 in an ICU. 285 (11%) microbial contaminations were revealed. The multivariate analysis found that the location in a hospital mortuary was associated with a lower risk of contamination (OR 0.43, 95% CI [0.2-0.91], p = 0.03). A procurement performed in the ICU was not associated with a significant increased risk (OR 0.62, 95% CI [0.26-1.48], p = 0.4).
Conclusion: According to our results, performing tissue procurement in dedicated non-sterile rooms could decrease the rate of allograft tissue contamination. This study also suggests that in daily clinical practice, transferring patients from ICU to SOR for tissue procurement could be avoided as it does not lead to less microbial contamination.

Background: Meat is a good source of protein in the human diet, and more than three-quarters of the world's population consumes it. It is the most perishable food item since it has enough nutrients to enable microbial growth. In underdeveloped nations, animals are routinely slaughtered and sold in unsanitary conditions, compromising the bacteriological quality and safety of the meat received from the animals.

Slaughterhouse environments are prone to microbial contamination, influenced by factors like set-up, size and area as well as disinfection practices. Thus, effective control measures are crucial to prevent the spread of pathogens and their contaminant genes (antimicrobial resistance genes and virulence factors) throughout the food chain. In the present study, we assessed the microbial contamination in environmental surfaces of three slaughterhouses located in the Jaén province (Spain).

The extensive agricultural use of the fungicide difenoconazole (DIF) and its associated toxicity increasingly damage ecosystems and human health. Thus, an urgent need is to develop environmentally friendly technological approaches capable of effectively removing DIF residues. In this study, strain A-3 was isolated for the first time which can degrade DIF efficiently.

Uneven distribution of precipitation and climate change have led to water shortages, adversely impacting numerous countries worldwide. Rooftop rainwater harvesting (RWH) has emerged as a crucial method for providing water for domestic uses. However, there are concerns about the quality of rainwater collected from roofs, as it may be contaminated with pollutants such as metals and microbiological pathogens.
