RESUMEN
Transcatheter aortic valve replacement (TAVR) carries a risk of high-grade AV block requiring cardiac implantable electronic device (CIED) implantation, which has been associated with a higher mortality rate. However, the outcomes of TAVR in patients with preexisting CIEDs are not well understood. We conducted a retrospective analysis of consecutive patients who underwent TAVR from December 2014 to December 2019 at our institution. Patients were categorized into 3 groups: preexisting CIED pre-TAVR (group 1), CIED implanted within 30 days after TAVR (group 2), and no CIED implanted (group 3). Cox proportional hazard was conducted to determine the primary end point of all-cause mortality. A total of 366 patients were included, of whom 93 (25.4%), 51 (13.9%), and 222 (60.7%) comprised group 1, 2, and 3, respectively. The median follow-up time was 2.3 years. The all-cause mortality rate was higher in group 1 than group 2 (hazard ratio [HR] 2.60, 95% confidence interval [CI] 1.09 to 6.18, p = 0.03) and group 3 (HR 1.96, 95% CI 1.24 to 3.08, p = 0.004). On the multivariate analysis, there was no statistically significant difference in mortality among the groups (group 1 vs group 2: HR 1.95, 95% CI 0.70 to 5.44, p = 0.20 and group 1 vs group 3: HR 1.27, 95% CI 0.66 to 2.43, p = 0.47). Preoperative hemoglobin ≤12 g/100 ml was an independent predictor of all-cause mortality (HR 1.75, 95% CI 1.10 to 2.80, p = 0.02). Group 1 had a higher 1 year congestive heart failure readmission rate (29%) than group 2 (17.6%) and group 3 (8.1%; p <0.0001). In conclusion, there was no difference in the adjusted long-term survival based on the CIED grouping. However, patients with preexisting CIEDs had higher all-cause mortality and 1-year congestive heart failure readmission rates owing to their higher co-morbidity burden, irrespective of their Society of Thoracic Surgeons score. This can be taken into account for preoperative risk stratification.

In this report, we describe the case of a woman with suspected COVID-19 immunization-induced probable catastrophic antiphospholipid syndrome. The patient is a 35-year-old female with a past medical history significant for antiphospholipid syndrome, not on anticoagulation, who presented with a 5-day history of abdominal pain and distention, nausea, vomiting, and shortness of breath. She had received her first dose of the Pfizer COVID-19 vaccine one day prior to the onset of symptoms. After extensive workup at an outside hospital, she was found to be in acute heart failure exacerbated by severe mitral and tricuspid regurgitation. She was transferred to our hospital for escalation of care. EKG showed evidence of prior inferior and septal myocardial infarction. Transesophageal echocardiogram (TEE) showed reduced ejection fraction, severe mitral and tricuspid regurgitation, and a left ventricular thrombus. Cardiac MRI showed subendocardial late gadolinium enhancement indicative of ischemia. However, CTA of the coronary vessels showed no signs of obstruction. Therefore, her acute heart failure was thought to be due to small vessel thrombosis secondary to antiphospholipid syndrome. During admission, she had several absence seizure-like episodes. CT head showed several hypodensities of the deep white matter and brain MRI demonstrated multiple hyperintense T2 FLAIR signal foci with restriction diffusion and enhancement involving the cerebral hemisphere, consistent with subacute strokes attributed to being secondary to antiphospholipid syndrome or embolic from the left ventricular thrombus. She was treated with heparin for suspected catastrophic antiphospholipid syndrome and high-dose corticosteroid therapy for concomitant Systemic Lupus Erythematosus (SLE). She was discharged in a stable condition.
RESUMEN
Issue: Pharmacy benefit managers (PBMs) are responsible for negotiating payment rates for a large share of prescription drugs distributed in the U.S. Recently, policymakers have expressed concern that certain PBMs' business practices may not be consistent with public policy goals to improve the value of pharmaceutical spending. Goal: We sought to explain key controversies related to PBM practices and their roles in driving value in the pharmaceutical market. Methods: Literature review and feedback from top experts on PBM business practices and potential policy solutions. Key Findings and Conclusion: In some cases, PBMs' use of rebates has contributed to high pharmaceutical costs, yet proposed solutions to the rebate controversy--including passing the rebate through to payers or patients--will not on their own reduce overall pharmaceutical spending without other policies that drive toward value. Policymakers seeking to reform pharmaceutical reimbursement beyond the practice of rebates will need to consider these changes in light of the recent mergers between PBMs and insurers and the entry of new market competitors.

Issue: Brand-name prescription drug prices are increasing in the United States, putting pressure on payers and patients. Some manufacturers have responded by offering outcomes-based contracts, in which rebate levels are tied to a specified outcome in the target population. Goal: To assess the expected benefits and limitations of outcomes-based pharmaceutical contracts in the U.S., including their potential impact on prescription drug spending. Methods: Semistructured interviews with payers, manufacturers, and policy experts. Key Findings: Pharmaceutical manufacturers and some private payers are increasingly interested in outcomes-based contracts for high-cost brand-name drugs. But the power of these contracts to curb spending is questionable, largely because their applicability is restricted to a small subset of drugs and meaningful metrics to evaluate their impact are limited. There is no evidence that these contracts have resulted in less spending or better quality. Conclusions: Outcomes-based contracts are intended to shift pharmaceutical spending toward more effective drugs, but their impact is unclear. Voluntary testing and rigorous evaluation of such contracts in the Medicare and Medicaid programs could increase understanding of this new model.

Patients with schizophrenia display numerous memory impairments. Examination of autobiographical memory distribution across the life span can constrain theories of how schizophrenia affects memory. Previously, schizophrenic patients were shown to produce fewer memories from early adulthood than from childhood or the recent past (A. Feinstein, T. E. Goldberg, B. Nowlin, & D. R. Weinberger, 1998), this temporal paucity corresponding with illness onset. The current study examined this issue further using a different (noncued) method. Age-matched schizophrenic patients (n = 21) and controls (n = 21) were to freely generate 50 episodes, after which they dated these memories. Patients generated fewer memories than did controls, especially from the recent decade. When the overall lower production of memories was controlled for, the groups displayed equivalent recency effects. It was concluded that patients' paucity of memories generated from the recent decade reflects encoding or acquisition problems, which may be associated with the illness period.
