Obesity and Transcatheter Aortic Valve Replacement.

Amidst an aging population and escalating obesity prevalence, elucidating the impact of obesity on transcatheter aortic valve replacement (TAVR) outcomes becomes paramount. The so-called "obesity paradox"-a term denoting the counterintuitive association of obesity, typically a risk factor for cardiovascular diseases, with improved survival outcomes in TAVR patients relative to their leaner or normal-weight counterparts-merits rigorous examination. This review comprehensively investigates the complex relationship between obesity and the clinical outcomes associated with TAVR, with a specific focus on mortality and periprocedural complications. This study aims to deepen our understanding of obesity's role in TAVR and the underlying mechanisms of the obesity paradox, thereby optimizing management strategies for this patient demographic, tailored to their unique physiological and metabolic profiles.

Hemopericardium: A Comprehensive Clinical Review of Etiology and Diagnosis.

Hemorrhagic pericardial effusion (HPE) is a subtype of pericardial effusion marked by the accumulation of serosanguineous or bloody fluid within the pericardial cavity. We present a case of a 65-year-old female who presented to the hospital with abdominal pain and was found to have pericardial effusion. The patient's condition evolved into cardiac tamponade, and employing diagnostic techniques such as imaging and pericardiocentesis, a substantial bloody effusion was uncovered, indicative of HPE. This report underscores the complexity of HPE diagnosis and examines the non-iatrogenic etiological factors contributing to HPE, focusing on three primary causes: malignancy, infection, and autoimmune disorders. It offers a detailed exploration of each etiology, backed by current medical literature and case studies. It outlines the diagnostic strategies pertinent to each cause, underscoring the need for a tailored approach to manage such cases. It emphasizes the importance of a meticulous and individualized diagnostic process, vital for accurate identification and effective management of this condition.

Comparison of Atherosclerotic Cardiovascular Risk Factors and Cardiometabolic Profiles Between Current and Never Users of Marijuana.

BACKGROUND: The relationship between marijuana use and cardiovascular health remains uncertain, with several observational studies suggesting a potential association with increased adverse atherosclerotic cardiovascular disease (ASCVD) outcomes. This study examined the relationship between marijuana use, ASCVD risk factors, and cardiometabolic risk profiles. METHODS: US adults (18-59 years) without cardiovascular disease were identified from the National Health And Nutrition Examination Survey (2005-2018) based on self-reported marijuana use. Current users (used within the past month) and never users were compared with assess the burden and control of traditional ASCVD risk factors and biomarkers, using inverse probability of treatment weighting to adjust for sociodemographic and lifestyle factors, including tobacco use. RESULTS: Of the 13 965 participants identified (mean age, 37.5; 51.2% female; 13% non-Hispanic Black), 26.6% were current users. Current users were predominantly male, low-income, and more likely to be concurrent tobacco users. Inverse probability of treatment weighting analysis showed no significant differences in the burden and control of hypertension (19.3% versus 18.8%, P=0.76; 79.8% versus 77.8%, P=0.75), dyslipidemia (24.0% versus 19.9%, P=0.13; 82% versus 75%, P=0.95), diabetes (4.8% versus 6.4%, P=0.19; 52.9% versus 50.6%, P=0.84), obesity (35.8% versus 41.3%, P=0.13), and physical activity levels (71.9% versus 69.3%, P=0.37) between current and never users. Likewise, mean 10-year ASCVD risk scores (2.8% versus 3.0%, P=0.49), 30-year Framingham risk scores (22.7% versus 24.2%, P=0.25), and cardiometabolic profiles including high-sensitivity C-reactive protein (3.5 mg/L versus 3.7 mg/L, P=0.65), neutrophil-lymphocyte ratio (2.1 versus 2.1, P=0.89), low-density lipoprotein (114.3 mg/dL versus 112.2 mg/dL, P=0.53), total cholesterol (191.2 mg/dL versus 181.7 mg/dL, P=0.58), and hemoglobin A1C (5.4% versus 5.5%, P=0.25) were similar between current and never users. CONCLUSIONS: This cross-sectional study found no association between self-reported marijuana use and increased burden of traditional ASCVD risk factors, estimated long-term ASCVD risk, or cardiometabolic profiles. Further studies are needed to explore potential pathways between adverse cardiovascular disease outcomes and marijuana use.

Safety of Catheter Ablation Therapy for Atrial Fibrillation in Cardiac Amyloidosis.

Background Despite the high burden of atrial fibrillation in cardiac amyloidosis (CA), the safety of catheter ablation therapy in CA is not well established. We sought to examine short-term safety outcomes following atrial fibrillation ablation in patients with CA compared with matched patients with dilated cardiomyopathy (DCM). Methods and Results Using data from the National Inpatient Sample, we identified all hospitalizations for atrial fibrillation ablation from the fourth quarter of 2015 through 2019. Admissions for CA and DCM were matched in a 1:5 ratio using propensity scores based on the following sociodemographics: age, sex, race or ethnicity, payor, median income, comorbidities, and hospital characteristics. We compared in-hospital outcomes between both cardiomyopathies. We identified 1395 unweighted hospitalizations (representing 6750 national hospitalizations) for atrial fibrillation ablation, out of which 45 (3.2%) were admissions for CA. Compared with DCM, patients with CA were older (72.9 versus 65.1 years), had a higher burden of prior stroke (20.0% versus 8.6%) and chronic kidney disease (53.3% versus 33.6%), and were less likely to have a prior implantable cardioverter-defibrillator (4.4% versus 23.0%). We successfully matched 42 CAs to 210 DCM hospitalizations. After matching, there was no difference in total complications (14.3% versus 10.5%, P=0.60), length-of-stay (3.1 versus 2.1 days, P=0.23), home disposition (97.6% versus 96.2%, P=0.65), and total charges ($137 250 versus $133 910, P=0.24). Conclusions In this nationally representative study of atrial fibrillation catheter ablation in CA, short-term safety outcomes and complication rates were similar to a propensity score-matched cohort of DCM. Further studies exploring long-term safety outcomes are needed.

Incidence, predictors and outcomes of new onset systolic heart failure following orthotopic liver transplant: A systematic review.

BACKGROUND: New onset Systolic heart failure (SHF), characterized by new onset left ventricular (LV) systolic dysfunction with a reduction in ejection fraction (EF) of <40%, is a common cause of morbidity and mortality among Orthotopic liver transplant (OLT) recipients. Therefore, we aimed to evaluate the prevalence, the pre-transplant predictors, and the prognostic impact of SHF post-OLT. METHODS: We conducted a systematic review of the literature using electronic databases MEDLINE, Web of Science, and Embase for studies reporting acute systolic heart failure post-liver transplant from inception to August 2021. RESULT: Of 2604 studies, 13 met the inclusion criteria and were included in the final systematic review. The incidence of new-onset SHF post OLT ranged from 1.2% to 14%. Race, sex, or body mass index did not significantly impact the post-OLT SHF incidence. Alcoholic liver cirrhosis, pre-transplant systolic or diastolic dysfunction, troponin, brain natriuretic peptide (BNP), blood urea nitrogen (BUN) elevation, and hyponatremia were noted to be significantly associated with the development of SHF post-OLT. The significance of MELD score in the development of post-OLT SHF is controversial. Pre-transplant beta-blocker and post-transplant tacrolimus use were associated with a lower risk of developing SHF. The average 1-year mortality rate in patients with SHF post-OLT ranged from 0.00% to 35.2%. CONCLUSION: Despite low incidence, SHF post-OLT can lead to higher mortality. Further studies are required to fully understand the underlying mechanism and risk factors.

Black and white proxy experiences and perceptions that influence advanced dementia care in nursing homes: The ADVANCE study.

BACKGROUND: Regional, facility, and racial variability in intensity of care provided to nursing home (NH) residents with advanced dementia is poorly understood. MATERIALS AND METHODS: Assessment of Disparities and Variation for Alzheimer's disease NH Care at End of life (ADVANCE) is a multisite qualitative study of 14 NHs from four hospital referral regions providing varied intensity of advanced dementia care based on tube-feeding and hospital transfer rates. This report explored the perceptions and experiences of Black and White proxies (N = 44) of residents with advanced dementia to elucidate factors driving these variations. Framework analyses revealed themes and subthemes within the following a priori domains: understanding of advanced dementia and care decisions, preferences related to end-of-life care, advance care planning, decision-making about managing feeding problems and acute illness, communication and trust in NH providers, support, and spirituality in decision-making. Matrix analyses explored similarities/differences by proxy race. Data were collected from June 1, 2018 to July 31, 2021. RESULTS: Among 44 proxies interviewed, 19 (43.1%) were Black, 36 (81.8%) were female, and 26 (59.0%) were adult children of residents. In facilities with the lowest intensity of care, Black and White proxies consistently reported having had previous conversations with residents about wishes for end-of-life care and generally better communication with providers. Black proxies held numerous misconceptions about the clinical course of advanced dementia and effectiveness of treatment options, notably tube-feeding and cardiopulmonary resuscitation. Black and White proxies described mistrust of NH staff but did so towards different staffing roles. Religious and spiritual beliefs commonly thought to underlie preferences for more intense care among Black residents, were rarely, but equally mentioned by race. CONCLUSIONS: This report refuted commonly held assumptions about religiosity and spirituality as drivers of racial variations in advanced dementia care and revealed several actionable facility-level factors, which may help reduce these variations.

ADVANCE-C: A Qualitative Study of Experiences Caring for Nursing Home Residents with Advanced Dementia During the COVID-19 Pandemic.

OBJECTIVES: Assessment of Disparities and Variation for Alzheimer's disease Nursing home Care at End of life (ADVANCE) is a multisite qualitative study of regionally diverse Nursing homes (NHs; N = 14) providing varied intensity of advanced dementia care. ADVANCE-C explored the experiences of NH staff and proxies during the COVID-19 pandemic. METHODS: Data collection occurred in five of the ADVANCE facilities located in Georgia (N = 3) and New York (N = 2). Semistructured qualitative interviews with NH staff (N = 38) and proxies of advanced dementia residents (N = 7) were conducted. Framework analyses explored five staff domains: care processes, decision making, organizational resources, vaccinations, and personal experience, and five proxy domains: connecting with residents, NH response, communicating with NH, decision making, and personal impact of the pandemic. RESULTS: Staff mentioned difficulties implementing infection control policies specifically for advanced dementia residents. Staff reported trust between the facility and proxies as critical in making decisions during the pandemic. All staff participants spoke about "coming together" to address persistent staffing shortages. Proxies described their role as an "emotional rollercoaster," emphasizing how hard it was being separate from their loved ones. The accommodations made for NH residents were not beneficial for those with advanced dementia. The majority of proxies felt NH staff were doing their best and expressed deep appreciation for their care. DISCUSSION: Caring for advanced dementia residents during the COVID-19 pandemic had unique challenges for both staff and proxies. Strategies for similar future crises should strive to balance best practices to contain the virus while maintaining family connections and person-centered care.

Nursing Home Staff Perceptions of End-of-Life Care for Residents With Advanced Dementia: A Multisite Qualitative Study.

Nursing homes (NHs) are an important site of death for residents with advanced dementia. Few studies have explored the experiences of NH staff about providing end-of-life care for residents with advanced dementia. This study aimed to describe NH staff perceptions on where end-of-life care should be delivered, the role of Medicare hospice care, and their experiences providing end-of-life care to residents with advanced dementia. Data from the Assessment of Disparities and Variation for Alzheimer's disease Nursing home Care at End of life study were used to explore the study objectives. Semistructured interviews with 158 NH staff working in 13 NHs across the United States were analyzed. Most NH staff endorsed the NH as a better site of death for residents with advanced dementia compared with a hospital. They expressed mixed perceptions about hospice care. However, regardless of their role, the staff expressed experiencing difficult emotions while providing end-of-life care to residents with dementia because of the close attachments they had formed with them and bearing witness to their decline. The findings show that most NH staff have strong emotional attachments to their dying residents with dementia and prefer to care for them at the NH rather than transfer them to the hospital.

Association of Nursing Home Organizational Culture and Staff Perspectives With Variability in Advanced Dementia Care: The ADVANCE Study.

IMPORTANCE: Regional, facility, and racial and ethnic variability in intensity of care provided to nursing home residents with advanced dementia is well documented but poorly understood. OBJECTIVE: To assess the factors associated with facility and regional variation in the intensity of care for nursing home residents with advanced dementia. DESIGN, SETTING, AND PARTICIPANTS: In the ADVANCE (Assessment of Disparities and Variation for Alzheimer Disease Nursing Home Care at End of Life) qualitative study, conducted from June 1, 2018, to July 31, 2021, nationwide 2016-2017 Medicare Minimum Data Set information identified 4 hospital referral regions (HRRs) with high (n = 2) and low (n = 2) intensity of care for patients with advanced dementia based on hospital transfer and tube-feeding rates. Within those HRRs, 14 facilities providing relatively high-intensity and low-intensity care were recruited. A total of 169 nursing home staff members were interviewed, including administrators, directors of nursing, nurses, certified nursing assistants, social workers, occupational therapists, speech-language pathologists, dieticians, medical clinicians, and chaplains. MAIN OUTCOMES AND MEASURES: Data included 275 hours of observation, 169 staff interviews, and abstraction of public nursing home material (eg, websites). Framework analyses explored organizational factors and staff perceptions across HRRs and nursing homes in the following 4 domains: physical environment, care processes, decision-making processes, and implicit and explicit values. RESULTS: Among 169 staff members interviewed, 153 (90.5%) were women, the mean (SD) age was 47.6 (4.7) years, and 54 (32.0%) were Black. Tube-feeding rates ranged from 0% in 5 low-intensity facilities to 44.3% in 1 high-intensity facility, and hospital transfer rates ranged from 0 transfers per resident-year in 2 low-intensity facilities to 1.6 transfers per resident-year in 1 high-intensity facility. The proportion of Black residents in facilities ranged from 2.9% in 1 low-intensity facility to 71.6% in 1 high-intensity facility, and the proportion of Medicaid recipients ranged from 45.3% in 1 low-intensity facility to 81.3% in 1 high-intensity facility. Factors distinguishing facilities providing the lowest-intensity care from those providing the highest-intensity care facilities included more pleasant physical environment (eg, good repair and nonmalodorous), standardized advance care planning, greater staff engagement in shared decision-making, and staff implicit values unfavorable to tube feeding. Many staff perceptions were ubiquitous (eg, adequate staffing needs), with no distinct pattern across nursing homes or HRRs. Staff in all nursing homes expressed assumptions that proxies for Black residents were reluctant to engage in advance care planning and favored more aggressive care. Except in nursing homes providing the lowest-intensity care, many staff believed that feeding tubes prolonged life and had other clinical benefits. CONCLUSIONS AND RELEVANCE: This study found that variability in the care of patients with advanced dementia may be reduced by addressing modifiable nursing home factors, including enhancing support for low-resource facilities, standardizing advance care planning, and educating staff about evidence-based care and shared decision-making. Given pervasive staff biases toward proxies of Black residents, achieving health equity for nursing home residents with advanced dementia must be the goal behind all efforts aimed at reducing disparities in their care.

Trust of Nursing Home Staff Caring for Residents with Advanced Dementia: A Qualitative Descriptive Study of Family Caregivers' Perspectives.

BACKGROUND/OBJECTIVES: Studies of interpersonal trust within nursing homes (NHs) is limited. This study aimed to describe the perspectives of interpersonal trust in NH staff among family caregivers of residents with advanced dementia. Additionally, comparisons of Black and White caregivers' perspectives were also explored. DESIGN: We used data generated from a parent study, Assessment of Disparities and Variation for Alzheimer's disease Nursing home Care at End of life (ADVANCE) to examine the experience of trust from the family caregivers' perspectives. PARTICIPANTS: Data generated from interviews with 44 family caregivers of residents with advanced dementia (Black n = 19 and White n = 25) were analyzed using thematic analysis. RESULTS/CONCLUSIONS: While both Black and White family caregivers experienced trust and mistrust, Black caregivers more often experienced differential mistrust. As differential mistrust is a new concept relative to trust, additional research is required to elucidate its meaning.
