Article Synopsis
  • The REGAIN trial found that spinal and general anesthesia provide similar outcomes regarding ambulation and survival after hip fracture surgery.
  • In a secondary analysis, researchers compared pain levels, analgesic use, and patient satisfaction between the two anesthesia types.
  • Results indicated that spinal anesthesia led to more severe pain in the first 24 hours post-surgery and higher prescription analgesic use at 60 days, while patient satisfaction remained comparable across both groups.

Article Synopsis
  • Despite the common use of antibiotics, surgical site infections remain prevalent in patients with fractures, prompting the need to explore better prevention methods.
  • An open-label randomized clinical trial tested the impact of intrawound vancomycin powder on reducing deep surgical site infections in high-risk patients undergoing tibial plateau or pilon fracture surgeries across multiple US trauma centers.
  • Results showed that the treatment group had a lower incidence of deep infections (6.4%) compared to the control group (9.8%), with the vancomycin specifically showing a significant effect on gram-positive infections, indicating its potential as an effective intervention in surgical settings.

A biological methanation system based on nutrient recycling via mixed culture microbial catabolism was investigated at mesophilic (37 °C) and thermophilic (55 °C) temperatures. At mesophilic temperatures, the formation of biofilms on two different types of material was assessed. Results showed that with intense mixing the biofilm reactors presented methanogenic capacities (per working volume) 50% higher than the ones operated with suspended cultures.

Ammonia inhibition mitigation in anaerobic digestion of high solids content of thermally hydrolysed secondary sewage sludge by the NH affinitive clinoptilolite and a strong acid type ion-exchange resin S957 was investigated. Continuous NH-N removal was achieved through ion-exchanging at both temperatures with average removals of 50 and 70% for the clinoptilolite and resin dosed reactors, respectively. Approximate 0.

A novel eco-engineered mixed anaerobic culture was successfully demonstrated for the first time to be capable of continuous regeneration in nutrient limiting conditions. Microbial catabolism has been found to support a closed system of nutrients able to enrich a culture of lithotrophic methanogens and provide microbial cell recycling. After enrichment, the hydrogenotrophic species was the dominating methanogens while a bacterial substratum was responsible for the redistribution of nutrients.
