Longitudinal transkingdom gut microbial approach towards decompensation in outpatients with cirrhosis.
The purpose of this study was to ascertain the crucial role of predicting the onset of initial decompensation development. It emphasizes the significance of transkingdom gut microbial interactions, including archaeal methanogens, as potential markers and predictors, and the need for a longitudinal approach to do so. The study included cirrhosis outpatients who were categorized into three groups: those with compensated cirrhosis in Group 1, those with one incidence of decompensation in Group 2, and those with more than one incidence of decompensation in Group 3. Group 3 was further divided based on stability or further decompensation. The presence of bacteria, viruses, and archaea, along with α/β diversity and temporal taxa fluctuations adjusted for clinical variables were analyzed. The study tracked 157 outpatients and found that between 28% and 47% of those patients developed outcomes. Baseline between those who remained stable/developed outcome: While no differences were seen in α/β diversity, commensals were lower and pathobionts were higher in those who decompensated. After decompensation: those experiencing their first decompensation showed a larger decrease in α/β-diversity, bacterial change and viral change vs those with further decompensation. Archaea: 19% had Methanobacter brevii, which was similar between/within groups. The study concluded that the largest changes in transkingdom gut microbial were observed in those reaching the first decompensation, compared with subsequent decompensating events.

Consumer choice between hospital-based and freestanding facilities for arthroscopy: Impact on prices, spending, and surgical complications.
The purpose of this study was to evaluate the impact of reference-based benefits on consumer choices, facility prices, employer spending, and surgical outcomes for orthopaedic procedures performed at ambulatory surgery centers. It found that the shift to reference-based benefits was associated with an increase in the utilization of freestanding ambulatory surgery centers by 14.3 percentage points for knee arthroscopy and by 9.9 percentage points for shoulder arthroscopy and a corresponding decrease in the use of hospital-based facilities.

Provider visit frequency and vascular access interventions in hemodialysis.
This study sought to determine whether more frequent face-to-face provider (physician and advanced practitioner) visits lead to more procedures and therapeutic interventions aimed at preserving arteriovenous fistulas and grafts and improved vascular access outcomes. It found that more frequent face-to-ace provider visits were associated with more procedures and therapeutic interventions aimed at preserving vascular accesses, but not with prolonged vascular access survival.
