Background/Objectives: Heart failure is the leading cause of hospital admission and mortality. Racial disparities have been demonstrated in various cardiovascular disorders; however, the data for in-hospital outcomes, complications, and procedural rates are limited. Methods: Utilizing the National Inpatient Sample (NIS) database, this retrospective cohort study included adult patients admitted with a principal diagnosis of heart failure. Coding for race and ethnicity in the NIS combines self-reported race and ethnicity provided by the data source into 1 data element (“RACE”). We compared the outcomes between various racial groups, focusing on mortality, the length of stay (LOS), hospital charges, and complications. Differences in the utilization of advanced therapies, including implantable cardiac defibrillators, cardiac resynchronization therapy (CRT), ventricular assist devices (VADs), and heart transplant, were also analyzed. Results: Out of 1,107,860 patients hospitalized with heart failure, 715,345 (64.57%) patients were White, 244,394 (22.06%) patients were Black, and 97,063 (8.31%) patients were Hispanic. Compared to White people, the odds of in-hospital mortality were lower among Black (aOR 0.74; 95% CI 0.68–0.81; p < 0.001) and Hispanic (aOR 0.78; 95% CI 0.69–0.88; p < 0.001) people. Complication rates including cardiogenic shock were found to be significantly lower in Black people (aOR 0.86; 95% CI 0.77–0.96; p < 0.001) and in Hispanic (aOR 0.72; 95% CI 0.63–0.81; p < 0.001) people. The rates of acute respiratory failure were also lower in Black (aOR 0.72; 95% CI 0.69–0.74; p < 0.001) and Hispanic (aOR 0.77; 95% CI 0.73–0.81; p < 0.001) people as opposed to White people. However, Black people were found to have higher rates of acute kidney injury (aOR 1.11; 95% CI 1.07–1.14; p < 0.001) and cardiac arrest (aOR 1.17; 95% CI 1.03–1.34; p = 0.02) compared to White people. Black people were less likely to receive advanced interventions, including cardiac resynchronization therapy (aOR 0.71; 95% CI 0.60–0.83; p < 0001), a ventricular assist device (aOR 0.45; 95% CI 0.34–0.59; p < 0.001), and heart transplants (aOR 0.57; 95% CI 0.42–0.77; p < 0.001), than White people. Hispanic people were found to have lower rates of ventricular assist device (aOR 0.49; 95% CI 0.33–0.72; p < 0.001) use than White people. Conclusions: These findings highlight significant racial disparities in mortality, secondary outcomes, and advanced therapy utilization in heart failure admissions. Further research is needed to identify the root factors for these disparities in order to guide targeted interventions to reduce this racial gap.

Long human ultra-conserved non-coding elements (UCNEs) do not have any sequence similarity to each other or other characteristics that make them unalterable during vertebrate evolution. We hypothesized that UCNEs have unique dinucleotide (DN) composition and arrangements compared to the rest of the genome. A total of 4272 human UCNE sequences were analyzed computationally and compared with the whole genomes of human, chicken, zebrafish, and fly. Statistical analysis was performed to assess the non-randomness in DN spacing arrangements within the entire human genome and within UCNEs. Significant non-randomness in DN spacing arrangements was observed in the entire human genome. Additionally, UCNEs exhibited distinct patterns in DN arrangements compared to the rest of the genome. Approximately 83% of all DN pairs within UCNEs showed significant (>10%) non-random genomic arrangements at short distances (2–6 nucleotides) relative to each other. At the extremes, non-randomness in DN spacing distances deviated up to 40% from expected values and were frequently associated with GpC, CpG, ApT, and GpG/CpC dinucleotides. The described peculiarities in DN arrangements have persisted for hundreds of millions of years in vertebrates. These distinctive patterns may suggest that UCNEs have specific DNA conformations.

Background/Objectives: Aortic stenosis (AS) is a critical valvular heart disease associated with significant morbidity and mortality if not managed promptly. Previous studies have highlighted the “weekend effect”, where the day of admission impacts outcomes in various cardiac conditions. This study evaluates the impact of weekend versus weekday admissions on outcomes in patients admitted with acutely decompensated aortic stenosis. Methods: We conducted a retrospective cohort study using the National Inpatient Sample database, focusing on patients emergently admitted with decompensated aortic stenosis. Patient outcomes were compared between those admitted on weekends (midnight Friday to midnight Sunday) and weekdays. Results: Among 94,320 patients included, 4537 (4.81%) were admitted on weekends. Weekend admissions were associated with significantly higher mortality (aOR 1.86; 95% CI 1.27–2.74) and longer hospital stays (mean increase 3.18 days; p < 0.001) compared to weekday admissions. Complication rates were also higher on weekends, including cardiogenic shock (aOR 2.1; 95% CI 1.54–2.87; p < 0.001), acute kidney injury (aOR 2.48; 95% CI 2.09–2.94; p < 0.001), and acute respiratory failure (aOR 2.88; 95% CI 2.38–3.49; p < 0.001). Additionally, weekend admissions had lower rates of transcatheter aortic valve replacement (TAVR) (aOR 0.49; 95% CI 0.40–0.62; p < 0.01) than weekday admissions. Conclusions: Patients with aortic stenosis admitted on weekends face significantly higher mortality, extended hospital stays, and increased complication rates compared to weekday admissions. Transcatheter aortic valve replacement (TAVR) rates were also lower for patients admitted on weekends. The “weekend effect” markedly influences outcomes, underscoring the need for hospital and administrative strategies to mitigate these adverse effects. Implementing standardized protocols and optimizing resource allocation during weekends could potentially reduce mortality and improve patient outcomes, offering a path to more equitable healthcare delivery.

Introduction: Spontaneous tumor lysis syndrome (TLS) is a rare, life-threatening metabolic complication that typically occurs in malignancies with high tumor burden. Early recognition is critical, even in the absence of a known malignancy, to prevent severe outcomes. Case Presentation: We report the case of an 89-year-old male with a history of chronic kidney disease, hyperparathyroidism, and myasthenia gravis, who experienced three episodes of TLS within 1 month. Initially, his metabolic disturbances were misattributed to dehydration. During his second admission, imaging revealed extensive lymphadenopathy, and a lymph node biopsy confirmed follicular helper T-cell lymphoma before his third hospitalization. Despite aggressive treatment, he developed metabolic encephalopathy and lost his decision-making capacity, while his family declined palliative care discussions. Conclusion: This case highlights the importance of considering TLS in patients with unexplained hyperkalemia, hyperuricemia, and hyperphosphatemia, even in the absence of a malignancy diagnosis. Early diagnosis and multidisciplinary care are essential to improve outcomes.

Background: Complete heart block (CHB) is a cardiac conduction disorder that can be fatal if not treated promptly. Malnutrition has been shown to have a significant impact on various cardiac conditions. Aim: The objective was to determine if the nutritional status influences the outcomes in patients with CHB. Methods: A retrospective study was conducted using the United States Inpatient Sample database on patients admitted with complete heart block. Outcomes were compared between the patients with and without concomitant malnutrition. Results: The study included 37,480 patients with complete heart block, of whom 603 (1.61%) had malnutrition. Compared to patients without malnutrition, patients with malnutrition had higher adjusted in-hospital mortality rates (aOR 2.61; 95% CI 1.46–3.48), longer length of stay (LOS) (mean increase 2.23 days; p < 0.01), and higher hospital charges (mean increase USD 76,907.32; p < 0.01). The malnourished group also had significantly higher rates of cardiogenic shock (aOR 2.80; 95% CI 1.56–5.03; p < 0.01) and acute respiratory failure (aOR 2.65; 95% CI 1.67–4.22; p < 0.01). Patients with malnutrition had significantly lower rates of permanent pacemaker (aOR 0.57; 95% CI 0.38–0.86; p < 0.01) and longer delay to permanent pacemaker intervention (mean increase 1.38 days; p = 0.014). The impact on outcomes was worse in patients with severe malnutrition compared to those with mild to moderate malnutrition. Conclusions: Malnutrition is associated with significantly worse outcomes in CHB admissions, including higher mortality, resource utilization, complications, and lower and delayed pacemaker intervention. Individualized and timely nutritional interventions might potentially play a key role in improving outcomes in these patients.
