Background: The optimal timing of pacemaker reimplantation following transvenous lead removal (TLR) of infected cardiac implantable electronic device (CIED) remains unclear. Objective: Our study aimed to assess the impact of timing to pacemaker reimplantation after TLR of infected CIED on hospital outcomes. Method: Using the Nationwide Readmissions Database, patients aged ≥18 years who underwent new pacemaker implantation with percutaneous approach following TLR of infected CIED from 2017 to 2020 were identified. The study population was stratified based on the timing of pacemaker reimplantation following TLR of infected CIED: early (<5 days) vs delayed (≥5 days). Weighted-propensity-score matched conditional multivariable logistic regressions were performed to determine the impact of the timing on various outcomes. Results: In our study, 469 (66.9%) patients received early device reimplantation, and 232 (33.1%) patients received delayed device reimplantation (≥5 days). Post-procedurally, patients in the delayed group had a higher risk of prolonged hospital stay (95% CI OR: 42.37 (6.36 – 282.11); p<0.01) and non-home discharge (95% CI OR: 2.00 (1.35 – 2.95), p<0.01). There was no significant difference between both groups in the early mortality, 30-day readmission, and procedural complications. Conclusion: Our study suggests that time-to-device reimplantation from TLR of infected CIED did not affect the overall short-term in-hospital outcomes. However, delayed device reimplantation was associated with a higher rate of prolonged hospital stay and non-home discharge.

Background: Recurrent pericarditis results from inflammasome activation and is associated with significant morbidity. Cannabidiol has been shown to block numerous inflammasome signaling pathways, including reducing transcription of pro-IL-1β and NLRP3, and inhibiting secretion of IL-1β and IL-6. Aim: To assess the impact of oral pharmaceutically manufactured (P-)cannabidiol in recurrent pericarditis patients (pts). Methods: Adult pts (≥18 years) with symptomatic, recurrent pericarditis (≥2 recurrences) were eligible for this open-label, multicenter study. Eligible pts had pericarditis chest pain with a numerical rating scale (NRS) pain score ≥4 within 7 days prior to enrollment, together with either elevated (≥1.0 mg/dL) C-reactive protein (CRP) within the prior 7 days or prior pericardial late gadolinium enhancement (LGE) on cardiac imaging. Pts had to be on chronic treatment with NSAIDs, colchicine or corticosteroids (any combination) with stable baseline (BL) doses. Oral P-cannabidiol was uptitrated to 10 mg/kg twice daily (BID), or maximum tolerated dose. The primary efficacy endpoint was improvement in NRS pain score at week 8 (WK8). A secondary efficacy endpoint among pts with elevated BL CRP was the percentage of pts with CRP normalization (≤0.5 mg/dL) at WK8. Results: 27 pts, mean age of 53 years (range 24-77), 18 of female sex, with a median of 3 prior pericarditis episodes were enrolled. CRP was ≥1.0 mg/dL in 10 pts (37%) at BL. Prior evidence of LGE was present in 21 pts (78%). At BL, 41% of pts were receiving corticosteroid therapy. The highest tolerated study medication dose was BID 10 mg/kg in 20 pts (74.1%), 7.5 mg/kg in 4 pts (14.8%), and 5 mg/kg in 3 pts (11.1%). All 27 pts (100%) completed the WK8 visit. Mean NRS score decreased by 3.7, from 5.8 at BL to 2.1 at WK8. In those with CRP elevation at BL, CRP normalized in 8 pts (80%) by WK8, with mean CRP decreasing from 5.71 to 0.31 mg/dL. Study medication was discontinued due to AEs in 2 pts (7.4%). 24 pts (89%) tolerated P-cannabidiol with a treatment response and proceeded into the 18-week extension period (EP) where background therapy is weaned. Conclusions: Among pts with symptomatic pericarditis recurrence, oral administration of P-cannabidiol led to a clinically relevant reduction in pericarditis chest pain (measured by NRS score) and in CRP. P-cannabidiol was shown to be safe and generally well tolerated, with the majority of pts reaching the target dose and continuing into the study EP.

Background: Carcinoid heart disease (CaHD) typically affects tricuspid and pulmonary valves and is associated with poor survival. To date, the role of right ventricular (RV) and atrial (RA) strain has not been evaluated in such cohort. Research Questions: To evaluate RV and RA strain patterns and assess their impact on survival and congestive heart failure (CHF) development. Methods: Retrospective study of CaHD patients (ICD 9/10 diagnosis of neuroendocrine tumor and echocardiographic evidence of CaHD prior to any surgical intervention; 2004-2019). Longitudinal strain was evaluated using speckle-tracking, RV/RA-focused view was used. RV strain was averaged from 3 and 6 segments for free wall (FWS) and global strain (GS), respectively. Auto-tracking with manual adjustment was done to ensure optimal tracking. The tracing of RV/RA endocardium was done with 15 points using the tricuspid valve annulus as a reference. The impact of strain parameters on mortality and CHF was evaluated with the Kaplan Meier and Cox proportional hazard analyses. Results: A total of 138 patients were included (mean age was 63 ± 10 years; 47% females). Median follow-up was 5.0 years (3.7-8.2). Significant RA and RV enlargement (72 and 79%, respectively) was more common than RV dysfunction (10%). The most common valvular disease > moderate was tricuspid regurgitation (TR; 97%) followed by pulmonary regurgitation (PR; 70%). RV GS mean was -21 + 6%, with FWS of -23 + 7%. The mean RA strain analysis revealed (93% sinus rhythm): a reservoir of 26 + 11%, a conduit of 14 + 8%, and an atrial contraction of 12 + 8%. Strain parameters were not associated with overall mortality. As opposed to PR/TR severity and RV/RA enlargement/dysfunction, patients with low RA reservoir strain (<23%) were more likely to develop CHF (adjusted-HR=1.80, p=0.04, 95% CI 1.04 - 3.134). Conclusions: Our findings suggests that CaHD patients have RV/RA dysfunction with overall reduced strain parameters. Patients with low RA reservoir had higher risk of CHF, but none of the RV/RA strain parameters were associated with excess mortality. This shows how strain analysis could complement other echocardiographic parameters in CaHD morbidity assessment.

Abstract The field of infectious diseases (ID) offers a rewarding career path and is widely viewed as an essential subspecialty in medicine. However, in recent years, these positive aspects have been overshadowed by concerns surrounding low fellowship match rates, undercompensation, and burnout. The Infectious Diseases Society of America Fellowship Training Program Directors Committee met in 2023, discussed the future of ID as a specialty, and sought to develop strategies to highlight the value and opportunities of ID for future generations, as well as underscore the importance of and provide tools for positive messaging to trainees about the subspecialty. This paper presents ideas generated at this meeting and is meant to serve as a reference for ID training program directors, as well as the wider ID community, in uplifting and shaping the future of the field.

ABSTRACT Medically important pathogenic fungi invade vertebrate tissue and are considered primary when part of their nature life cycle is associated with an animal host and are usually able to infect immunocompetent hosts. Opportunistic fungal pathogens complete their life cycle in environmental habitats or occur as commensals within or on the vertebrate body, but under certain conditions can thrive upon infecting humans. The extent of host damage in opportunistic infections largely depends on the portal and modality of entry as well as on the host’s immune and metabolic status. Diseases caused by primary pathogens and common opportunists, causing the top approximately 80% of fungal diseases [D. W. Denning, Lancet Infect Dis, 24:e428–e438, 2024, https://doi.org/10.1016/S1473-3099(23)00692-8 ], tend to follow a predictive pattern, while those by occasional opportunists are more variable. For this reason, it is recommended that diseases caused by primary pathogens and the common opportunists are named after the etiologic agent, for example, histoplasmosis and aspergillosis, while this should not be done for occasional opportunists that should be named as [causative fungus] [clinical syndrome], for example, Alternaria alternata cutaneous infection. The addition of a descriptor that identifies the location or clinical type of infection is required, as the general name alone may cover widely different clinical syndromes, for example, “rhinocerebral mucormycosis.” A list of major recommended human and animal disease entities (nomenclature) is provided in alignment with their causative agents. Fungal disease names may encompass several genera of etiologic agents, consequently being less susceptible to taxonomic changes of the causative species, for example, mucormycosis covers numerous mucormycetous molds.

BACKGROUND: Packed red blood cell (pRBC) transfusions in patients undergoing surgery for cancer are given to treat anemia or acute hemorrhage. Evidence indicates that pRBC transfusions are associated with poor perioperative and oncological outcomes. The ARCA-1 (Perioperative Care in the Cancer Patient-1) study was designed to test the association between perioperative pRBC transfusions and postoperative morbidity and mortality in patients undergoing cancer surgery. The primary hypothesis of our study was that perioperative pRBC transfusions have a negative impact on postoperative morbidity and 1-year mortality. METHODS: ARCA-1 was an international multicenter prospective observational cohort study. Participating centers enrolled a minimum of 30 consecutive adult patients with cancer who underwent surgery with curative intent. The primary end point was all-cause mortality 1 year after major cancer surgery. Secondary end points were rates of perioperative blood product use, 1-year cancer-specific mortality, overall survival, and 30-day morbidity and mortality. We performed a propensity score matching analysis to adjust for selection bias. A multivariable logistic regression model was fitted to estimate the effects of significant covariates on 1-year mortality, cancer-related mortality, and overall survival. RESULTS: A total of 1079 patients were included in the study. The rate of perioperative pRBC transfusions was 21.1%. Preoperative comorbidities, including anemia, American Society of Anesthesiologists (ASA) score of III to IV, a history of coronavirus disease 2019 (COVID-19), myocardial infarction, stroke, need for dialysis, history of blood transfusions, and metastatic disease were statistically significantly more frequent in transfused patients compared to nontransfused patients. The 1-year mortality rate was higher in transfused patients before (19.7% vs 6.5%; P < .0001) and after (17.4% vs 13.2%; P = .29) propensity score matching. 1-year mortality was 1.97 times higher in transfused than in no-transfused patients (odd ratio [OR], 1.97; 95% confidence interval [CI], 1.13–3.41). The odds of 1-year cancer mortality for patients who had perioperative pRBCs was 1.82 times higher (OR, 1.82; 95% CI, 0.97–3.43) compared to those who did not receive perioperative pRBC transfusion. The effect of perioperative pRBC transfusion on overall survival was also significant (hazard ratio [HR], 1.85; 95% CI, 1.15–2.99). Transfused patients also had a higher rate of 30-day postoperative mortality before (3.5% vs 0.7%; P = .0009) and after propensity score matching (4.2% vs 1.8%; P = .34). CONCLUSIONS: This international, multicenter observational study showed that perioperative pRBC transfusion was associated with an increased mortality risk.

Abstract Background Cardiac metastasis from neuroendocrine tumors (NET) is rare and has been thought to potentially result in life threatening sequalae. Peptide receptor radionucleotide therapy (PRRT), such as Lutetium-177 (Lu-177) DOTATATE, has been validated as effective treatment for patients with NET who have progressed on somatostatin analogue (SSA) therapy and more recently suggested for use in SAA-naïve higher risk grade 2 and grade 3 NETs. However, Lu-177 DOTATATE therapy has been found to have potentially serious adverse effects both locally and systemically. Overall, the clinical significance of cardiac metastasis of NET, as well as the safety and efficacy of Lu-177 DOTATATE in this cohort, has not been thoroughly evaluated. Purpose This study assessed the outcomes and clinical consequences of cardiac metastatic involvement in patients with NET. Furthermore, this study investigated the safety of Lu-177 DOTATATE therapy in patients with cardiac metastases from NET. Methods All patients who underwent 68Ga-DOTATATE positron emission tomography for evaluation of NET across three tertiary centers between 2016 and 2022 were retrospectively evaluated. Patients with evidence of cardiac metastasis were further evaluated. Baseline characteristics, treatment modality, and clinical outcomes including mortality, arrhythmia or conduction disease, carcinoid heart disease, and heart failure admissions were recorded. Patients with cardiac metastases were grouped and compared based on therapeutic modality (conservative therapy with surveillance or SSA, Lu-177 DOTATATE therapy, or surgical resection of metastases). Results From 3253 patients with NET, 51 patients were identified to have cardiac metastases (mean age 66.7 ± 12.2 years, 54% male). Three patients underwent surgical resection of cardiac metastases, and in two of whom this was concomitant while undergoing valve surgery for carcinoid heart disease. Patients with cardiac metastasis had significantly higher mortality than patients without cardiac metastasis (HR 2.12, 95%CI 1.00 – 4.52, p = 0.049, Figure 1A). Median follow-up from diagnosis of cardiac metastasis was 3.64 years [IQR 1.59 – 5.64]. There was no significant difference in clinical outcomes between patients that received Lu-177 DOTATATE therapy (n = 27) and conservative therapy (n = 21). Specifically, there was no significant difference in mortality risk at five years post the diagnosis of cardiac metastasis between these groups (p = 0.47, Figure 1B). Conclusion Patients with cardiac metastasis from NETs have worse clinical outcomes than NET patients without cardiac metastatic involvement. Lu-177 DOTATATE therapy appears to be safe in patients with cardiac metastasis from NET.Figure 1AFigure 1B

Abstract Background Recurrent pericarditis (RP) is a chronic autoinflammatory disease mediated by IL-1 that requires long-term treatment. While the 2015 European Society of Cardiology Guidelines position IL-1 pathway inhibition only after corticosteroids, complications associated with long-term steroid use underscore the importance of steroid-sparing strategies. Rilonacept, an IL-1α and IL-1β cytokine trap, is the only FDA-approved treatment for RP (available since April 2021). RESONANCE, an ongoing 5-year non-interventional US registry of patients (pts) with RP, has collected real-world data from pts cared for by cardiologists with a focus on pericardial disease, with a goal of informing contemporary RP clinical management. Purpose Analysis of temporal trends in RP management from RESONANCE. Methods From a database cut-off (DCO) on 21 December 2023, patient demographics and disease characteristics are reported for 242 active RP pts (excluding RHAPSODY prior participants) at 20 US sites (median [Q1:Q3] 2.1 [1.5:2.6] years and 556 patient-years [PY] of observation). Complete medication class use data were available for 239 pts (total 546 PY). Proportional medication class use prior to initiating rilonacept was analyzed annually across the observation period. Results Mean (standard deviation) age at DCO was 50.2 (16.6) years; 58.1% were female. Median [Q1:Q3] disease duration at DCO from index pericarditis episode was 3.1 [2.2:5] years. Median [Q1:Q3] number of prior recurrences at enrollment was 3 [2:5]. Prior to rilonacept availability, NSAIDs/Colchicine/Aspirin represented the highest proportion of treatment (73% of PY); steroid use was 9% of PY, IL-1 pathway inhibition (anakinra) was 13% of PY, and conventional synthetic disease modifying antirheumatic drugs (csDMARDs) were 0.46% PY (no RP-specific treatment was 5% of PY) (Fig 1). In the years since rilonacept availability, proportional IL-1 pathway inhibition use has increased, from 13% of PY in 2020-21 to 26% of PY in 2023, driven by an increase in rilonacept use (6%, 13%, 16% of PY in 2021, 2022, and 2023, respectively). Over that same period, proportional NSAIDs/Colchicine/Aspirin use (57%-63% of PY) has been consistently 6-times more than proportional steroid use (10%-11% of PY). Among pts who initiated rilonacept (n=81), similar proportions transitioned from NSAIDs/Colchicine/Aspirin as from corticosteroids (Fig 2), a robust trend observed each year. Of those pts transitioning from corticosteroids, 1/3 had used corticosteroids for &lt;30 days and 1/3 for &gt;6 months. Conclusions Real-world data from the RESONANCE registry reveal a temporal shift in RP management in US centers with RP-focused cardiologists, with increased proportional IL-1 pathway inhibition use since rilonacept availability in 2021. Advancing beyond 2015 guideline recommendations, IL-1 pathway inhibition is often being used as steroid-sparing treatment, i.e., after colchicine instead of chronic corticosteroids.
