Abstract
CONTEXT Despite major efforts in research, practice, and policy, racial and ethnic disparities in health and health care persist in the United States. Interventions in collaboration with governmental public health may provide ways to address these persistent racial and ethnic health and health care disparities and improve health outcomes. OBJECTIVE To conduct a comprehensive review of health equity interventions performed in collaboration with public health agencies. DESIGN This scoping review includes intervention studies from Ovid MEDLINE, PsycINFO, and Academic Search Premier, published between 2017 and 2023. The search strategy used terminology focused on 4 concepts: race/ethnicity, equity, health departments, and epidemiologic studies. ELIGIBILITY CRITERIA The following inclusion criteria were determined a priori: (1) intervention tailored to reduce racial/ethnic health disparities, (2) public health department involvement, (3) health outcome measures, (4) use of epidemiologic study methods, (5) written in English, (6) implemented in the United States, (7) original data (not a commentary), and (8) published between January 2017 and January 2023. MAIN OUTCOME MEASURES This review focused primarily on 4 dimensions of racial health equity interventions including intervention components, intervention settings, intervention delivery agents, and intervention outcomes. RESULTS This review indicated that health equity interventions involving public health agencies focused on the following categories: (1) access to care, (2) health behavior, (3) infectious disease testing, (4) preventing transmission, and (5) cancer screening. Critical strategies included in interventions for reaching racial/ethnic minoritized people included using community settings, mobile clinics, social media/social networks, phone-based interventions, community-based workers, health education, active public health department involvement, and structural/policy change. CONCLUSIONS This scoping review aims to provide an evidence map to inform public health agencies, researchers, and funding agencies on gaps in knowledge and priority areas for future research and to identify existing health equity interventions that could be considered for implementation by public health leaders.

Association of Cumulative Systolic Blood Pressure With Left Atrial Function in the Setting of Normal Left Atrial Size: The Atherosclerosis Risk in Communities (ARIC) Study. J Am Soc Echocardiogr 2024:S0894-7317(24)00220-7.

Abstract
BACKGROUND Lower left atrial (LA) function is associated with increased risk for cardiovascular disease events; data on risk factors for impaired LA function are limited. We evaluated the effect of cumulative systolic blood pressure (cSBP) from midlife to older age on LA strain in adults with normal LA size. METHODS We included participants in the Atherosclerosis Risk in Communities study with LA strain measured on the visit 5 echocardiogram (2011-13), excluding those with atrial fibrillation and LA volume index >34 mL/m2. The cSBP was calculated from visit 1 (1987-89) through visit 5. Linear regression models were used to evaluate associations between cSBP and LA strain measures. RESULTS A total of 3,859 participants with a mean (SD) age of 75.2 (5.0) years were included in the analysis; 725 (18.8%) were Black and 2,342 (60.7%) were women. After adjusting for demographics, cardiovascular disease risk factors, heart failure, and coronary heart disease, each 10 mm Hg increase in cSBP was associated with 0.32% (95% CI, -0.52%, -0.13%) and 0.37% (95% CI, -0.51%, -0.22%) absolute reduction in LA reservoir and conduit strain, respectively. Associations were attenuated after adjustment for left ventricular (LV) systolic and diastolic function and mass (-0.12%: 95% CI, -0.31, 0.06 for reservoir strain; and -0.24%: 95% CI -0.38%, -0.10% for conduit strain). In subgroup analyses, the association of cSBP with conduit strain was statistically significant among those with normal LV systolic and diastolic function. CONCLUSIONS Cumulative exposure to elevated blood pressure from midlife to late life was modestly associated with lower LA reservoir and conduit strain in older adults with normal LA size, mostly related to the effect of blood pressure on LV function and mass. However, the association of cSBP and LA conduit strain in subgroups with normal LV function suggests that LA remodeling in response to hypertension occurs before LV dysfunction is detected on echocardiography.

[PMID: 38339479 PMCID: PMC10857412 DOI: 10.3390/s24030761] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/07/2023] [Revised: 01/14/2024] [Accepted: 01/16/2024] [Indexed: 02/12/2024]
Abstract
BACKGROUND Combination devices to monitor heart rate/rhythms and physical activity are becoming increasingly popular in research and clinical settings. The Zio XT Patch (iRhythm Technologies, San Francisco, CA, USA) is US Food and Drug Administration (FDA)-approved for monitoring heart rhythms, but the validity of its accelerometer for assessing physical activity is unknown. OBJECTIVE To validate the accelerometer in the Zio XT Patch for measuring physical activity against the widely-used ActiGraph GT3X. METHODS The Zio XT and ActiGraph wGT3X-BT (Actigraph, Pensacola, FL, USA) were worn simultaneously in two separately-funded ancillary studies to Visit 6 of the Atherosclerosis Risk in Communities (ARIC) Study (2016-2017). Zio XT was worn on the chest and ActiGraph was worn on the hip. Raw accelerometer data were summarized using mean absolute deviation (MAD) for six different epoch lengths (1-min, 5-min, 10-min, 30-min, 1-h, and 2-h). Participants who had ≥3 days of at least 10 h of valid data between 7 a.m-11 p.m were included. Agreement of epoch-level MAD between the two devices was evaluated using correlation and mean squared error (MSE). RESULTS Among 257 participants (average age: 78.5 ± 4.7 years; 59.1% female), there were strong correlations between MAD values from Zio XT and ActiGraph (average r: 1-min: 0.66, 5-min: 0.90, 10-min: 0.93, 30-min: 0.93, 1-h: 0.89, 2-h: 0.82), with relatively low error values (Average MSE × 106: 1-min: 349.37 g, 5-min: 86.25 g, 10-min: 56.80 g, 30-min: 45.46 g, 1-h: 52.56 g, 2-h: 54.58 g). CONCLUSIONS These findings suggest that Zio XT accelerometry is valid for measuring duration, frequency, and intensity of physical activity within time epochs of 5-min to 2-h.

Association of abnormal p-wave parameters with brain MRI morphology: The atherosclerosis risk in communities neurocognitive study (ARIC-NCS). Pacing Clin Electrophysiol 2023; 46:951-959. [PMID: 36924350 PMCID: PMC10440299 DOI: 10.1111/pace.14687] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/03/2022] [Revised: 01/23/2023] [Accepted: 02/18/2023] [Indexed: 03/18/2023]
Abstract
BACKGROUND Recent evidence indicates that abnormal P-wave parameters (PWPs)-ECG markers of atrial myopathy-are associated with incident dementia, independent of atrial fibrillation (AF) and clinical ischemic stroke. However, the mechanisms remain unclear and may include subclinical vascular brain injury. Hence, we evaluated the association of abnormal PWPs with brain MRI correlates of vascular brain injury in the Atherosclerosis Risk in Communities Neurocognitive Study (ARIC-NCS). METHODS ARIC-NCS participants who underwent 3T brain MRI scans in 2011-2013 were included. PWPs were measured from standard 12-lead ECGs. Brain MRI outcomes included cortical infarcts, lacunar infarcts, cerebral microhemorrhages, brain volumes, and white matter disease (WMD) volume. We used weighted multivariable logistic and linear regression to evaluate the associations of abnormal PWPs with brain MRI outcomes. RESULTS Among 1715 participants (mean age, 76.1 years; 61% women; 29% Black), 797 (46%) had ≥1 abnormal PWP. After multivariable adjustment, including adjusting for prevalent AF, abnormal P-wave terminal force in lead V1 (aPTFV1) and prolonged P-wave duration (PPWD) were associated with increased odds of both cortical (OR 1.41; 95% CI, 1.14 to 1.74 and OR 1.30; 95% CI, 1.04 to 1.63, respectively) and lacunar infarcts (OR 1.36; 95% CI, 1.15 to 1.63 and OR 1.37; 95% CI, 1.15 to 1.65, respectively). Advanced interatrial block (aIAB) was associated with higher odds of subcortical microhemorrhage (OR 2.04; 95% CI, 1.36 to 3.06). Other than a significant association between aPTFV1 with lower parietal lobe volume, there were no other significant associations with brain or WMD volume. CONCLUSION In this exploratory analysis of a US community-based cohort, ECG surrogates of atrial myopathy are associated with a higher prevalence of brain infarcts and microhemorrhage, suggesting subclinical vascular brain injury as a possible mechanism underlying the association of atrial myopathy with dementia.

Abstract
BACKGROUND Atrial fibrillation (AF) is associated with higher risks of ischemic stroke (IS) and dementia. Whether alterations in left atrial (LA) function or size-atrial myopathy-confound these associations remains unknown. OBJECTIVES The purpose of this study was to examine the association of prevalent and incident AF with ischemic stroke and dementia in the ARIC (Atherosclerosis Risk In Communities) study, adjusting for LA function and size. METHODS Participants at visit 5 (2011-2013) with echocardiographic LA function (reservoir, conduit, contractile strain, and emptying fraction) and size (maximal, minimal volume index) data, and without prevalent stroke or dementia were followed through 2019. For analysis, we used time-varying Cox regression. RESULTS Among 5,458 participants (1,193 with AF, mean age of 76 years) in the stroke analysis and 5,461 participants (1,205 with AF, mean age of 75 years) in the dementia analysis, 209 participants developed ischemic stroke, and 773 developed dementia over 7.1 years (median). In a demographic and risk factor-adjusted model, AF was significantly associated with ischemic stroke (HR, 1.63; 95% CI: 1.11-2.37) and dementia (HR: 1.38, 95% CI: 1.13-1.70). After additionally adjusting for LA reservoir strain, these associations were attenuated and no longer statistically significant (stroke [HR: 1.33, 95% CI: 0.88-2.00], dementia [HR: 1.15, 95% CI: 0.92-1.43]). Associations with ischemic stroke and dementia were also attenuated and not statistically significant after adjustment for LA contractile strain, emptying fraction, and minimal volume index. CONCLUSIONS AF-ischemic stroke and AF-dementia associations were not statistically significant after adjusting for measures of atrial myopathy. This proof-of-concept analysis does not support AF as an independent risk factor for ischemic stroke and dementia.

Abstract
Introduction:
Observational evidence from real world data suggests that providing cardiac rehabilitation (CR) to older patients with incident atrial fibrillation (AF) is associated with lower risk of all-cause mortality and re-hospitalization. We leveraged these data to estimate cost-effectiveness of extending Medicare coverage for exercise based CR to older AF patients.
Hypotheses:
Exercise based CR for older patients with incident AF is cost-effective at a conventional willingness to pay threshold of $50,000 per quality adjusted life year (QALY).
Methods:
A cost-utility analysis was conducted using a decision tree to compare initiation of exercise-based CR with standard care versus standard care alone for older patients with incident AF. Outcomes considered were re-hospitalization and all-cause mortality. A systematic review was conducted to obtain inputs for model parameters. Paucity of research did not allow meta-analyses. Estimated risks & related uncertainty intervals for re-hospitalization and death were obtained from a published propensity score matched analysis of electronic health records data pooled from 41 health care organizations in the United States of America and the United Kingdom. In this study, CR + standard care versus standard care alone was associated with lower odds of all-cause mortality (odds ratio, 0.32, 95% uncertainty interval 0.29, 0.35) and re-hospitalization (odds ratio, 0.56, 95% uncertainty interval, 0.53, 0.59) over 18 months of follow-up. Estimations for costs and QALY were obtained from USA based, peer-reviewed, published studies. Probabilistic sensitivity analysis was conducted to account for uncertainty in estimates. Data analysis was performed from healthcare perspective using Microsoft Excel software.
Results:
In a hypothetical cohort of 10,000 older patients with incident AF (mean age, 68 years, 71% male, 84% White), estimated costs per QALY gained for CR + standard care was about $2659 and standard care alone was about $2455. Providing CR was associated with an estimated incremental cost of $10,374 per incremental QALY gained. Probabilistic sensitivity analysis showed that CR had a >75% chance of being cost-effective at a willingness to pay threshold of $50,000 per QALY.
Conclusions:
Findings from our simulation study based on real world evidence suggest that extending Medicare coverage for exercise based CR to older patients with incident AF may be potentially cost-effective. Implementing such a policy change requires evidence from a large randomized controlled trial that overcomes design-related limitations identified in previous observational and small, randomized interventional research studies.

Abstract
Abstract
Background
The adjuvanted recombinant zoster vaccine (RZV), first approved in 2017, has high, long-lasting efficacy against herpes zoster (HZ) and a clinically acceptable safety profile. In addition to the prevention of HZ in adults aged ≥50 years, the non-live RZV can be used from age 18 years in individuals with immunocompromised (IC) conditions. We reviewed the evolving landscape of national recommendations for RZV use.
Methods
National health authority and vaccination committee websites of countries where RZV is approved were searched in March 2022.
Results
Of 41 countries where RZV is licensed, 14 (Australia, Austria, Canada, Czech Republic, Germany, Ireland, Italy, Netherlands, New Zealand, Saudi Arabia, Spain, Switzerland, UK, US) provide national recommendations related to RZV; the majority are preferential to RZV or only recommend RZV. Overall, seven and seven countries recommend immunisation from age 50 years or 60/65 years, respectively. Of the seven countries that recommend immunisation from age 60/65 years, five recommend immunisation in individuals from age 50 years with comorbidities/IC conditions. Five countries recommend immunisation from age 18/19 years in individuals at increased risk of HZ due to immunosuppressive disease/treatment. In addition, six national recommendations refer to RZV safety and nine address prior HZ vaccination and/or infection. All recommendations outlined the RZV administration schedule.
Conclusions
Although national recommendations can inform decision making in clinical practice, RZV recommendations are not available in all licensed countries. The recommendations highlight a trend in favour of the use of RZV for the prevention of HZ in older individuals and those with IC conditions.
Main messages: An increasing number of countries are providing recommendations for the use of RZV for the prevention of HZ in older individuals and those with IC conditions.
Key messages
• An increasing number of countries are providing recommendations for the use of RZV for the prevention of HZ in older individuals.
• An increasing number of countries are providing recommendations for the use of RZV for the prevention of HZ in IC conditions.

Abstract
Abstract
Background
There have been several case reports of herpes zoster (HZ) following COVID-19 disease and vaccination. We conducted a non-systematic literature search to elucidate the global effects of the COVID-19 pandemic on the incidence of HZ.
Methods
The literature search was performed in October 2021 using PubMed and Embase. The search string was herpes zoster AND COVID-19. Publications were manually reviewed; case reports were removed.
Results
Three retrospective studies reported the risk of HZ following COVID-19 disease. One study (Bhavsar, 2021) used two US databases and found higher risk of HZ following COVID-19 disease (relative risk [RR]=1.15) and COVID-19 hospitalisation (RR = 1.21), respectively. A strong association between HZ and COVID-19 disease (RR = 5.27) was also reported in a study of the University of Florida patient registry (Katz, 2021). The third study (Barda, 2021) reported no association between COVID-19 disease and risk of HZ (RR = 0.82). In two of the three observational studies in Israel (Furer, 2021 and Barda, 2021), the incidence of HZ was increased following COVID-19 vaccination. The third study (Shasha, 2021) found no association (RR = 1.07). Other studies included a report in Brazil (Maia, 2021) that demonstrated a 35% increase in HZ diagnoses during the pandemic versus pre-pandemic and a published model (La, 2021) that estimated the declining uptake of recombinant zoster vaccine in the US may result in 63,117 avoidable HZ cases in those who remain unvaccinated in 2021.
Conclusions
Emerging data suggest that the COVID-19 pandemic may have increased the risk of HZ and negatively impacted HZ vaccine uptake. Therefore, there is an important need to increase awareness of HZ and HZ vaccination during the pandemic.
Key messages
• There is a need to increase awareness of HZ and HZ vaccination during the COVID-19 era.
• Further studies are needed to fully understand the impact of COVID-19 on the risk of HZ.

Abstract
Pulmonary hypertension (PH) complicates the treatment of interstitial lung disease (ILD) patients resulting in poor functional status and worse outcomes. Early recognition of PH in ILD is important for initiating therapy and considering lung transplantation. However, no standard exists regarding which patients to screen for PH‐ILD or the optimal method to do so. The aim of this study was to create a risk assessment tool that could reliably predict PH in ILD patients. We developed a PH‐ILD Detection tool that incorporated history, exam, 6‐min walk distance, diffusion capacity for carbon monoxide, chest imaging, and cardiac biomarkers to create an eight‐component score. This tool was analyzed retrospectively in 154 ILD patients where each patient was given a score ranging from 0 to 12. The sensitivity (SN) and specificity (SP) of the PH‐ILD Detection tool and an area‐under‐the‐curve (AUC) were calculated. In this cohort, 74 patients (48.1%) had PH‐ILD. A score of ≥6 on the PH‐ILD Detection tool was associated with a diagnosis of PH‐ILD (SN: 86.5%; SP: 86.3%; area‐under‐the‐curve: 0.920, p < 0.001). The PH‐ILD Detection tool provides high SN and SP for detecting PH in ILD patients. With confirmation in larger cohorts, this tool could improve the diagnosis of PH in ILD and may suggest further testing with right heart catheterization and earlier intervention with inhaled treprostinil and/or lung transplant evaluation.

Abstract
IMPORTANCE Atrial myopathy-characterized by alterations in left atrial (LA) function and size-is associated with ischemic stroke, independent of atrial fibrillation (AF). Electrocardiographic markers of atrial myopathy are associated with dementia, but it is unclear whether 2-dimensional echocardiographic (2DE)-defined LA function and size are associated with dementia. OBJECTIVE To examine the association of LA function and size with incident dementia. DESIGN, SETTING, AND PARTICIPANTS The Atherosclerosis Risk in Communities (ARIC) study is a community-based prospective cohort. An exploratory, retrospective analysis was conducted. ARIC centers are located in Forsyth County, North Carolina; Jackson, Mississippi; Washington County, Maryland; and suburban Minneapolis, Minnesota. For this analysis, visit 5 (2011-2013) served as the baseline. Participants without prevalent AF and stroke and who had 2DEs in 2011-2013 were included and surveilled through December 31, 2019. EXPOSURES LA function (reservoir strain, conduit strain, contractile strain, emptying fraction, passive emptying fraction, and active emptying fraction), and LA size (maximal and minimal volume index) as evaluated by 2DE. MAIN OUTCOMES AND MEASURES Dementia cases were identified using in-person and phone cognitive assessments, hospitalization codes, and death certificates. Cox proportional hazards models were used. RESULTS Among 4096 participants (mean [SD] age, 75 [5] years; 60% women; 22% Black individuals), 531 dementia cases were ascertained over a median follow-up of 6 years. Dementia incidence for the lowest LA quintile was 4.80 for reservoir strain, 3.94 for conduit strain, 3.29 for contractile strain, 4.20 for emptying fraction, 3.67 for passive emptying fraction, and 3.27 for active emptying fraction per 100 person-years. After full-model adjustments, there were statistically significant associations between measures of LA function and dementia; the hazard ratios (HRs) from the lowest vs highest quintile for reservoir strain were 1.98 (95% CI, 1.42-2.75); for conduit strain, 1.50 (95% CI, 1.09-2.06); for contractile strain, 1.57 (95% CI, 1.16-2.14); for emptying fraction, 1.87 (95% CI, 1.31-2.65); and for active emptying fraction, 1.43 (95% CI, 1.04-1.96). LA passive emptying fraction was not significantly associated with dementia (HR, 1.26 [95% CI, 0.93-1.71]). Dementia incidence for the highest LA maximal volume index quintile was 3.18 per 100 person-years (HR for highest vs lowest quintile, 0.77 [95% CI, 0.58-1.02]) and for the highest minimal volume index quintile was 3.50 per 100 person-years (HR for the highest vs lowest quintile, 0.95 [95% CI, 0.71-1.28]). Both measures were not significantly associated with dementia. These findings were robust to sensitivity analyses that excluded participants with incident AF or stroke. CONCLUSIONS AND RELEVANCE In this exploratory analysis of a US community-based cohort, several echocardiographic measures of lower LA function were significantly associated with an increased risk of subsequent dementia. Measures of LA size were not significantly associated with dementia risk. These findings suggest that impaired LA function may be a risk factor associated with dementia.

Abstract
Introduction
Fractured Neck of Femur (FNOF) patients are complex. A mortality project identified topics for a peer-led teaching programme.
Method
Eight bite-sized case-based sessions were devised, to provide a framework to approach the following topics: Anaemia, delirium/dementia, ECG abnormalities, metastatic cancer, osteoporosis, renal disease, respiratory disease, and vascular complications. Attendees were asked to complete pre- and post- teaching programme questionnaires using a Likert Scale to indicate agreement with statements relating to the topic areas chosen (1=strongly disagree and 5=strongly agree).
Result
Pre-programme questionnaire: respondents were neutral (average 3.04) when asked whether topic areas were currently “well managed”. Attendees lacked confidence, indicating preparedness as neutral (average 3.35). Trainees agreed that they would benefit from teaching (average 4.56).
Post-programme questionnaire: increased confidence was reported when considering preparedness (average 4.3). Attendees felt the teaching programme was “accessible” and the “topics well-chosen”. 100% of attendees regarded the teaching as ‘excellent’ or ‘very-good’.
Conclusions
Matching patient needs to an educational programme is important.
The “bite-sized” nature of the programme paired with case-based learning increased confidence. A peer-led teaching programme is a positive response to themes emerging from morbidity and mortality reviews.

Abstract
At the onset of the global pandemic of COVID-19 (SARS-CoV-2), guidelines recommended using regional anaesthesia for caesarean section in preference to general anaesthesia. National figures from the UK suggest that 8.75% of over 170,000 caesarean sections are performed under general anaesthetic. We explored whether general anaesthesia rates for caesarean section changed during the peak of the pandemic across six maternity units in the north-west of England. We analysed anaesthetic information for 2480 caesarean sections across six maternity units from 1 April to 1 July 2020 (during the pandemic) and compared this information with data from 2555 caesarean sections performed at the same hospitals over a similar period in 2019. Primary outcome was change in general anaesthesia rate for caesarean section. Secondary outcomes included overall caesarean section rates, obstetric indications for caesarean section and regional to general anaesthesia conversion rates. A significant reduction (7.7 to 3.7%, p < 0.0001) in general anaesthetic rates, risk ratio (95%CI) 0.50 (0.39-0.93), was noted across hospitals during the pandemic. Regional to general anaesthesia conversion rates reduced (1.7 to 0.8%, p = 0.012), risk ratio (95%CI) 0.50 (0.29-0.86). Obstetric indications for caesarean sections did not change (p = 0.17) while the overall caesarean section rate increased (28.3 to 29.7%), risk ratio (95%CI) 1.02 (1.00-1.04), p = 0.052. Our analysis shows that general anaesthesia rates for caesarean section declined during the peak of the pandemic. Anaesthetic decision-making, recommendations from anaesthetic guidelines and presence of an on-site anaesthetic consultant in the delivery suite seem to be the key factors that influenced this decline.

Abstract
Abstract
Background
Atrial fibrillation (AF) is the most common arrhythmia in patients with cancer. Management of AF in patients with cancer poses unique challenges. Long-term use of antiarrhythmic drug (AAD) therapy lacks evidence of efficacy in this population and poses risk of drug interactions. Catheter ablation is a well-established treatment modality for AAD resistant symptomatic AF and in patients with heart failure. Nevertheless, the effectiveness and safety of catheter ablation in patients with cancer is not well established.
Method
We retrospectively analyzed consecutive patients who underwent catheter ablation for AF, with either history of cancer (other than non-melanoma skin cancer) within 5-years prior or exposure to systemic anthracycline and/or thoracic radiation therapy at any time.
Results
The study included 162 patients. The mean age was 65.5 (26–84 years) years and 50% were female. Overall 133 (82%) patients had freedom from AF at 12 months following ablation. Of these 74 (54%) required post-ablation AAD, 18 (13.5%) required another ablation within the first 12 months and 9 (6.7%) required both AAD and a second ablation to maintain sinus rhythm. There were 14 adverse events (8.6%); 5 access site and 4 non-access site bleeding, 2 strokes, 2 cardiac tamponade and 1 pulmonary vein stenosis with ≈1% serious complications.
Conclusion
The success of catheter ablation for AF and the incidence of procedure related complications in patients with a history of recent cancer or prior exposure to cardiotoxic therapies are similar to that reported in patients without a history of cancer and hence if needed, it should be considered in select patients.

Abstract
Abstract
Purpose
Cardiovascular complications of chimeric antigen receptor T-cell (CAR T-cell) therapy are poorly understood. We examined the incidence, predictors and impact of new or worsening cardiomyopathy in patients undergoing CAR T-cell therapy.
Methods
All patients with refractory or relapsed non-Hodgkin's lymphoma, undergoing CAR T-cell therapy at collaborative institutes underwent serial echocardiograms at baseline and within 7 days after developing high-grade cytokine release syndrome (CRS), and were followed for all-cause mortality. New or worsening cardiomyopathy was defined as a reduction in left ventricular ejection fraction (LVEF) >10% from baseline to <50% during the index hospitalization.
Results
Among 187 consecutive CAR T-cell therapy patients, 116 (50 Grade ≤1 CRS, 66 Grade ≥2 CRS) had >1 echocardiogram performed and were included in this analysis. The median age was 63 (range 19–80) years, 42% were women, 91% were Caucasian. A total of 12 (10.3%) patients developed new or worsening cardiomyopathy with a decline in LVEF from 58±6% to 36±7% within a median of 12.5 (range 2–24) days of CAR T-cell infusion. In multivariable analyses, older age, prior stem cell transplantation, baseline angiotensin-converting enzyme inhibitor use and CRS grade ≥2 were associated with the development of cardiomyopathy. Patients who developed cardiomyopathy were more likely to require vasopressor support (p=0.004) and mechanical ventilation (p=0.014). LVEF improved in 9/12 (75%) patients. CAR T-cell associated cardiomyopathy did not impact overall mortality or cancer response to CAR-T cell therapy.
Conclusions
Patients undergoing CAR T-cell therapy are at risk of developing cardiomyopathy and hemodynamic instability. Pre-CAR T-cell therapy cardiovascular risk stratification and echocardiogram surveillance during therapy should be considered for prompt identification and mitigation of cardiac complications.

Abstract
BACKGROUND Patients with polycythemia vera with high hematocrit have increased risk of venous thromboembolism (VTE). OBJECTIVE To determine whether high hematocrit in the general population is also associated with elevated VTE risk. METHODS The prospective Atherosclerosis Risk in Communities Study performed a complete blood count in 13 891 adults aged 45 to 64 in 1987 to 1989. We identified incident hospitalized VTEs through 2015 and performed proportional hazards regression analyses using race-sex-specific categorization of hematocrit percentiles (ie, <5th, 5th to <25th, 25th to <75th, 75th to <95th, and 95th-100th percentiles, with the 25th to <75th percentile serving as the reference). RESULTS Over a median follow-up of 26 years, 800 participants had an incident venous thrombosis of the leg and/or a pulmonary embolism. There was a nonlinear association of hematocrit with VTE incidence, with risk elevated 72% for participants above the 95th percentile of hematocrit compared with the reference. Specifically, hazard ratios (95% confidence intervals) of incident VTE were 1.27 (0.91-1.76), 1.06 (0.87-1.28), 1 (reference), 1.17 (0.98-1.40) and 1.72 (1.30-2.27) across the 5 hematocrit percentiles, adjusted for age, race, sex, body mass index, smoking status and pack-years, and other confounding variables. The association of high hematocrit with VTE was limited to provoked VTE, with little evidence for unprovoked VTE. Hemoglobin above the 95th percentile also was associated with an increased risk of VTE. In contrast, there were no significant associations of platelet, leukocyte, neutrophil, or lymphocyte counts with VTE incidence. CONCLUSION High hematocrit and hemoglobin in a general middle-aged population sample were associated with increased long-term risk of VTE, particularly provoked VTE.

Abstract
Background With recurrence rates after primary cytoreductive surgery (CRS) in excess of 50 per cent, repeat CRS is being performed increasingly, but survival outcomes have not been reported widely. This study examined the outcomes following repeat CRS for appendiceal cancer with peritoneal surface malignancy (PSM), and evaluated its feasibility and safety. Methods A retrospective cohort of patients who had surgery between 1996 and 2018 were analysed. Patients who underwent a single CRS procedure with or without heated intraperitoneal chemotherapy (HIPEC) were compared with those who had multiple procedures with or without HIPEC. Perioperative morbidity and survival outcomes were analysed. Results Some 462 patients were reviewed, 102 of whom had repeat procedures. For high‐grade tumours, patients who had a single CRS procedure had significantly reduced overall survival (OS) compared with those who had repeat CRS (55·6 versus 90·7 months respectively; P = 0·016). For low‐grade tumours, there was no difference in OS (P = 0·153). When patients who had a single procedure were compared with those who had multiple procedures, there was no significant difference in major morbidity (P = 0·441) or in‐hospital mortality (P = 0·080). For multiple procedures, no differences were found in major morbidity (P = 0·262) or in‐hospital mortality (P = 0·502) when the first procedure was compared with the second. For low‐grade cancers, the peritoneal carcinomatosis index was a significant prognostic factor for OS (hazard ratio (HR) 1·11, 95 per cent c.i. 1·05 to 1·17; P < 0·001), whereas for high‐grade cancers repeat CRS (HR 0·57, 0·33 to 0·95; P = 0·033), complete cytoreduction score (HR 1·55, 1·01 to 2·40; P = 0·046) and presence of signet ring cells (HR 2·77, 1·78 to 4·30; P < 0·001) were all significant indicators of long‐term survival. Conclusion In selected patients presenting with PSM from epithelial appendiceal neoplasms, repeat CRS performed in high‐volume centres could provide survival benefits.
