Abstract Background Patients with ulcerative colitis (UC) or Crohn’s disease (CD) are at increased risk of herpes zoster (HZ); however, relevant cost and healthcare resource utilization (HCRU) data are limited. Methods We estimated HCRU (hospitalization, emergency department [ED], and outpatient visits) and costs in patients with UC or CD, with and without HZ, using administrative claims data (October 2015–February 2020). HCRU and costs (2020 US dollars) were compared at 1 month, 1 quarter, and 1 year after the index date, using propensity score adjustment and generalized linear models. Results In total, 20 948 patients were included: UC+/HZ+ (n = 431), UC+/HZ– (n = 10 285), CD+/HZ+ (n = 435), and CD+/HZ– (n = 9797). Patients with HZ had higher all-cause HCRU rates and all-cause total healthcare costs relative to those without HZ. In the first month, adjusted incidence rate ratios (aIRRs) for hospitalizations and ED visits for patients with UC and HZ compared with UC alone were 2.87 (95% confidence interval [CI], 1.93–4.27) and 2.66 (95% CI,1.74–4.05), respectively; for those with CD and HZ, aIRRs were 3.34 (95% CI, 2.38–4.70) and 3.31 (95% CI, 2.32–4.71), respectively, compared with CD alone (all P < .001). Adjusted cost differences in UC and CD cohorts with HZ over the first month were $2189 and $3774, respectively, chiefly driven by higher inpatient costs. The incremental impact on HCRU and costs in cohorts with HZ predominantly occurred during the first quarter following diagnosis. Conclusions HZ is associated with increased HCRU and costs in patients with UC and CD, especially shortly after diagnosis.

Objective: To compare conventional low-temperature storage of transplant donor livers [static cold storage (SCS)] with storage of the organs at physiological body temperature [normothermic machine perfusion (NMP)]. Background: The high success rate of liver transplantation is constrained by the shortage of transplantable organs (eg, waiting list mortality >20% in many centers). NMP maintains the liver in a functioning state to improve preservation quality and enable testing of the organ before transplantation. This is of greatest potential value with organs from brain-dead donor organs (DBD) with risk factors (age and comorbidities), and those from donors declared dead by cardiovascular criteria (donation after circulatory death). Methods: Three hundred eighty-three donor organs were randomized by 15 US liver transplant centers to undergo NMP (n = 192) or SCS (n = 191). Two hundred sixty-six donor livers proceeded to transplantation (NMP: n = 136; SCS: n = 130). The primary endpoint of the study was “early allograft dysfunction” (EAD), a marker of early posttransplant liver injury and function. Results: The difference in the incidence of EAD did not achieve significance, with 20.6% (NMP) versus 23.7% (SCS). Using exploratory, “as-treated” rather than “intent-to-treat,” subgroup analyses, there was a greater effect size in donation after circulatory death donor livers (22.8% NMP vs 44.6% SCS) and in organs in the highest risk quartile by donor risk (19.2% NMP vs 33.3% SCS). The incidence of acute cardiovascular decompensation at organ reperfusion, “postreperfusion syndrome,” as a secondary outcome was reduced in the NMP arm (5.9% vs 14.6%). Conclusions: NMP did not lower EAD, perhaps related to the inclusion of lower-risk liver donors, as higher-risk donor livers seemed to benefit more. The technology is safe in standard organ recovery and seems to have the greatest benefit for marginal donors.

Background: Mortality remains high in patients with ST-segment–elevation myocardial infarction (STEMI) complicated by cardiogenic shock (CS), and early reperfusion has been shown to improve outcomes. We analyzed the association between first medical contact (FMC)-to-percutaneous coronary angiography time with mortality and major adverse cardiovascular events among patients with STEMI with and without CS. Methods: We performed a retrospective analysis of the Vancouver Coastal Health Authority STEMI registry, including all patients with STEMI who received primary percutaneous coronary angiography between January 1, 2010, and December 31, 2020, and stratified them by presence or absence of CS at hospital arrival. The primary outcome was in-hospital mortality, the secondary outcome was in-hospital major adverse cardiovascular events, defined as a composite of the first occurrence of mortality, cardiac arrest, heart failure, intracerebral hemorrhage, cerebrovascular accident, or reinfarction. Mixed effects logistic regression with restricted cubic splines was used to estimate the relationships between FMC-to-device time and the outcomes in the CS and non-CS groups. Results: 2929 patients were included, 9.4% (n=275) had CS. Median FMC-to-device time was 113.5 (interquartile range, 93.0–145.0) and 103.0 (interquartile range, 85.0–130.0) minutes for patients with CS and without CS, respectively. More patients with CS had FMC-to-device times above guideline recommendations (76.6% versus 54.1%, P <0.001). Between 60 and 90 minutes, for each 10-minute increase in FMC-to-device time, absolute mortality for patients with CS increased by 4% to 7%, whereas for patients without CS, it increased by <0.5%. Conclusions: Among patients with STEMI undergoing primary percutaneous coronary angiography, reperfusion delays among patients with CS are associated with significantly worse outcomes. Strategies to reduce FMC-to-device times for patients with STEMI presenting with CS are required.
