Outcomes and complications of heart failure with iron deficiency anemia: a nationwide analysis.

INTRODUCTION: Heart failure is a pressing public health concern, affecting millions in the United States and projected to rise significantly by 2030. Iron deficiency, prevalent in nearly half of ambulatory heart failure patients, contributes to anemia and diminishes patient outcomes. In this study, we aim to evaluate the impact of iron deficiency anemia on acute heart failure hospitalizations outcomes. METHODS: Utilizing the 2019 National Inpatient Sample (NIS) database, a retrospective observational study assessed 112,864 adult patients hospitalized with heart failure and 7,865 cases also had a concomitant diagnosis of iron deficiency anemia (IDA). RESULTS: Among 112,864 heart failure hospitalizations in 2019, approximately 7% had concomitant iron deficiency anemia (IDA). Heart failure patients with IDA exhibited distinct demographic characteristics, with females comprising 51.1% (p < 0.01) and higher rates of complicated hypertension (p < 0.01), complicated diabetes (p < 0.01), and peripheral vascular disease (p < 0.01). Adjusted mean LOS for patients with IDA was significantly longer at 1.31 days (95% CI 0.71-1.47; p < 0.01), persisting in both HFpEF and HFrEF subgroups. While total hospital charges were comparable in HFpEF, HFrEF patients with IDA incurred significantly higher charges ($13427.32, 95% CI: 1463.35-$25391.29, p = 0.03) than those without IDA. Complications such as atrial fibrillation and acute kidney injury were notably more prevalent in HFpEF and HFrEF patients with IDA. CONCLUSION: The study highlighted that iron deficiency in heart failure patients leads to extended hospital stays, increased costs, and heightened risks of specific complications, particularly in HFrEF. Our study emphasized the implications of IDA in patients with heart failure ranging from prolonged hospitalizations and increased costs. Addressing iron deficiency is crucial, given its substantial impact on heart failure hospitalizations and outcomes, emphasizing the need for proactive diagnosis and management.

The efficacy of non-pharmacological and non-pacing therapies in preventing vasovagal syncope: Tilt training, physical counter pressure maneuvers, and yoga - A systematic review and meta-analysis.

BACKGROUND: Vasovagal syncope (VVS) is a prevalent condition characterized by a sudden drop in blood pressure and heart rate, leading to a brief loss of consciousness and postural control. Recurrent episodes of VVS significantly impact the quality of life and are a common reason for emergency department visits. Non-pharmacological interventions, such as tilt training, physical counter pressure maneuvers, and yoga, have been proposed as potential treatments for VVS. However, their efficacy in preventing VVS remains uncertain. METHODS: A systematic review and meta-analysis were conducted following PRISMA guidelines. PubMed, Web of Science, and Embase were searched up to March 2023 for randomized controlled trials comparing non-pharmacological interventions with control in preventing VVS recurrence. The primary outcome was the recurrence rate of VVS episodes. RESULTS: A total of 1130 participants from 18 studies were included in the meta-analysis. The overall mean effect size for non-pharmacological interventions versus control was 0.245 (95 % CI: 0.128-0.471, p-value <0.001). Subgroup analysis showed that yoga had the largest effect size (odds ratio 0.068, 95 % CI: 0.018-0.250), while tilt training had the lowest effect size (odds ratio 0.402, 95 % CI: 0.171-0.946) compared to control. Physical counter pressure maneuvers demonstrated an odds ratio of 0.294 (95 % CI: 0.165-0.524) compared to control. CONCLUSION: Non-pharmacological interventions show promise in preventing recurrent VVS episodes. Yoga, physical counter pressure maneuvers, and tilt training can be considered as viable treatment options. Further research, including randomized studies comparing pharmacological and non-pharmacological approaches, is needed to evaluate the safety and efficacy of these interventions for VVS treatment.

Safety and Efficacy of Direct Oral Anticoagulant in Addition to Antiplatelet Therapy After Acute Coronary Syndrome: A Systemic Review and Meta-analysis of 53,869 Patients.

INTRODUCTION: Significant progress has been made in the management of patients with acute coronary syndrome (ACS) during the past few decades. However, the role of direct oral anticoagulants (DOACs) in post-ACS prophylactic therapy remains unknown. This study aims to assess the efficacy and safety of DOACs plus antiplatelet treatment (APT) after ACS. METHODS: A systematic literature search was conducted to identify randomized clinical trials comparing DOACs plus APT with APT alone after ACS. The primary efficacy end points were cardiovascular mortality, myocardial infarction, all-cause mortality, and stroke and systemic embolization (SSE). The primary safety end point was major bleeding. The random-effects model was used to calculate relative risk (RR) and corresponding 95% CIs. RESULTS: Nine trials with a total of 53,869 patients were identified, with 33,011 (61.2%) in the DOACs plus APT group and 20,858 (38.8%) in the APT alone group. The use of DOACs did not decrease the risk of cardiovascular death (RR = 0.87; 95% CI, 0.75-1.01; P = 0.08; I2 = 0%) or myocardial infarction (RR = 0.90; 95% CI, 0.80-1.02; P = 0.10; I2 = 6%). However, the risk of SSE was significantly lower in patients who received DOACs plus APT compared with APT alone (RR = 0.67; 95% CI, 0.50-0.90; P = 0.008). Moreover, all-cause mortality was significantly lower in the DOACs plus APT group (RR = 0.83; 95% CI, 0.71-98; P = 0.03; I2 = 0%). However, the risk of major bleeding was significantly higher in patients treated with DOACs plus APT compared with APT alone (RR = 2.53; 95% CI, 1.96-3.26; P < 0.01; I2 = 0%), as was the risk of nonmajor bleeding (RR = 2.27; 95% CI, 1.51-3.41; P < 0.01). IMPLICATIONS: DOACs plus APT for the prevention of left ventricular thrombus in patients with ACS were associated with a lower risk of SSE and all-cause mortality but increased the risk of major and nonmajor bleeding. The benefits and risks of this approach should be weighed based on a patient's individual clinical characteristics.

The Association Between Myocardial Bridging and Hypertrophic Cardiomyopathy and Their Implications on Percutaneous Coronary Intervention Outcomes: A Retrospective Study.

Hypertrophic cardiomyopathy (HCM) is a complex cardiac disorder, often associated with adverse outcomes, including sudden cardiac death. Myocardial bridging (MB), where a coronary artery segment traverses intramurally within the myocardium, complicates coronary blood flow dynamics. This retrospective study investigates the relationship between MB and HCM and their impact on percutaneous coronary intervention (PCI) outcomes. Data from the 2019 National Inpatient Sample (NIS), representing 20% of U.S. hospitalizations, was utilized. Patients with both HCM and MB undergoing PCI were identified and analyzed. The study assessed inpatient outcomes, including mortality, length of stay, hospital cost, and post-PCI complications (atrial fibrillation, acute kidney injury, bleeding, coronary dissection). Patients with HCM and MB exhibited distinct demographics. The study did not find significant associations between HCM/MB and inpatient mortality, length of stay, or hospital cost. However, HCM patients had a higher incidence of atrial fibrillation and acute kidney injury post-PCI (aOR 2.33, 95% CI 1.46 to 3.71, p ≤ 0.001). MB was linked to increased occurrences of acute heart failure (aOR 0.62, 95% CI 0.42-0.92, p = 0.02) and post-PCI bleeding (aOR 4.88, 95% CI 1.17-20.2, p = 0.03). This nationwide study reveals unique demographic profiles for HCM and MB patients. Notably, HCM patients face higher risks of post-PCI complications, including atrial fibrillation and acute kidney injury. These findings provide fresh insights into the MB-HCM relationship and its implications for PCI outcomes. They emphasize the need for tailored interventions and improved patient management in cases involving both HCM and MB.

Body Mass Index and Outcomes of Transcatheter Aortic Valve Replacement: A Retrospective Observational Study.

The influence of body mass index (BMI) on Transcatheter Aortic Valve Replacement (TAVR) outcomes has been the focus of several previous studies. In this study, we examined the relationship between BMI and various clinical outcomes following TAVR procedures. A comprehensive analysis was conducted using a large cohort of patients who underwent TAVR. In this study, we identified patients who underwent Transcatheter aortic valve replacement (TAVR) in the year 2020. Procedure Classification System (ICD-10-PCS) codes were used to identify TAVR cases. The weighted final study sample included 77319 TAVR hospitalizations. Patients were categorized into 5 groups based on their Body Mass Index (BMI. Our findings revealed that there was no significant difference in in-hospital mortality among different BMI groups when compared to patients with a normal BMI (20 to 24.9). patients with a BMI of 25 or higher demonstrated a statistically significant shorter duration of hospitalization compared to those with a normal BMI. patients with a BMI ranging between 30 and 39.9 exhibited decreased hospitalization costs when compared to patients with a normal BMI. Moreover, our study revealed a decrease in atrial fibrillation, acute heart failure and acute kidney injury complications following TAVR in patients with above-normal BMI. Despite similar in-hospital mortality across BMI groups, having a BMI of 25 or greater is associated with improved immediate outcomes following TAVR. These benefits in overweight and obese patients are consistent with findings described in recent literature. Further studies are warranted to explore the underlying mechanisms and potential implications of these associations, as well as to optimize patient selection and management strategies for TAVR procedures.

Impact of COVID-19 Pandemic on the Outcomes of Acute Coronary Syndrome.

During the pandemic, health care resources were primarily focused on treating COVID-19 infections and its related complications, with various Clinical units were converted to COVID-19 units, This study aims to investigate the impact of the COVID-19 pandemic on the clinical course of patients who had developed acute coronary syndrome (ACS) including ST-elevation myocardial infarction (STEMI). In this large nationwide observational study utilizing National Inpatient Sample 2019 and 2020.The primary outcomes of our study were in-hospital mortality, length of stay (LOS), total hospital charges and time from admission to percutaneous coronary intervention (PCI). Using the National Inpatient Sample 2020 database we found 32,355,827 hospitalizations in 2020 and 521,484 of which had a primary diagnosis of STEMI that met our criteria. Patients with COVID-19 infection were similar in mean age, more likely to be men, were treated in the same hospital settings as those without COVID-19 and had higher rates of diabetes with chronic complications. These patients had a similar prevalence of traditional coronary artery disease risk factors including hypertension, peripheral vascular disease and obesity. There was higher inpatient mortality (adjusted odds ratios 3.10; 95% CI, 2.40-4.02; P < 0.01) and LOS (95% CI 1.07-2.25; P < 0.01) in STEMI patient with concurrent COVID-19 infection. The average time from admission to PCI was significantly higher among unstable angina (UA) and None ST-segment elevated myocardial infarction (NSTEMI) in patients with a secondary diagnosis of COVID-19 infection compared to patients without: 0.45 days (95% CI: .155-758; P < 0.01). The COVID-19 pandemic had a significant impact on the treatment of patients with ACS, resulting in increased inpatient mortality, higher costs, and longer lengths of stay. During the pandemic, for patients with UA and NSTEMI the time from admission to PCI was significantly longer in patients with a secondary diagnosis of COVID-19 compared to patients without. When comparing ACS outcomes between pre-pandemic to pandemic periods (2019 versus 2020), the 2020 data showed higher mortality, higher hospital costs, and a decrease in LOS. Finally, the time from admission to PCI was longer for UA and NSTEMI in 2020 but not for patients with STEMI.

The clinicopathological features of programmed death ligand-1 expression in colorectal carcinoma.

BACKGROUND: Few studies have addressed the clinicopathological features of colorectal cancer (CRC) that express programed death-ligand 1 (PD-L1). Various assays and scoring methodologies were used and thus inconsistent results were obtained. In this study, we aimed to investigate the relationship of PD-L1 expression in CRC with various clinicopathological variables using a standardized assay and scoring algorithm. DESIGN: Tissue microarrays were constructed from 91 random cases of CRC diagnosed at King Hussein Cancer Center (KHCC). Immunohistochemical (IHC) staining using the monoclonal antibody 22C3 was performed. Scoring using the standard "Combined Positive Score" (CPS) method was done. CPS of ≥1 was considered positive. Various clinicopathological features were collected from the medical records of the patients. RESULTS: Of the 91 cases, 49 (53.8%) were PD-L1 positive (CPS ≥1). PD-L1 expression was more frequent among moderately differentiated carcinomas (43 of 72 (59.7%) were positive compared to 6 of 19 (31.5%) poorly differentiated cases (P = 0.029)); among node negative cases (21 of 24 (87.5%) N0 cases were PD-L1 positive in contrast to 28 of 67 (41.8%) N1/N2 cases (P = <0.001)); among mucinous subtype (12 of 15 (80%) of cases (P = 0.02)); and among mismatch repair deficient (dMMR) (16 of 16 (100%) versus 11 of 30 (36.6%) MMR proficient (P = <0.001)). Age, gender, localization, and T or M stages were not significantly associated with PD-L1 expression. CONCLUSION: PD-L1 expression in CRC is associated with favorable prognostic features; namely, lower grade, N0, mucinous variant, and dMMR tumors.

Changing Trends in Estrogen Receptors/Progesterone Receptors/Human Epidermal Growth Factor Receptor 2 Prevalence Rates Among Jordanian Patients With Breast Cancer Over the Years.

PURPOSE: Estrogen receptors (ERs), progesterone receptors (PRs), and human epidermal growth factor receptor 2 (HER2) are the mainstay of breast cancer management, and their prevalence rates vary among different populations possibly related to ethnic/genetic and/or socioeconomic status. In a previous study conducted at the King Hussein Cancer Center (published 2006), Jordan ER/PR/HER2 rates for patients diagnosed in 2003-2004 were 50.8%/57.5%/17.5%, respectively. The aim of this study is to revisit the prevalence rates to see if they have changed over the years with changing socioeconomic status. MATERIALS AND METHODS: We retrieved clinicopathologic data of all patients (1,185) diagnosed with breast cancer during 2018. The data included age, histologic type, grade, and ER/PR/HER2 status as determined by immunohistochemistry and/or fluorescence in situ hybridization for HER2. RESULTS: The mean age of patients was 52 (median = 51, range = 25-92) years, and the majority (73.2%) had invasive carcinoma of no special type. ER/PR/HER2 were 77.0%/72.4%./23.8%, respectively. Triple-negative breast cancers were 10.1%. In comparison with previous results of 2006, the changes are statistically significant. Similar changes were seen in other Middle Eastern populations. The current rates are close to those of Western populations. CONCLUSION: Rates of ER/PR/HER2 expression have significantly changed and are close to those of Western populations for ER/PR. We propose that such changes are secondary to the adoption of a westernized lifestyle and socioeconomic changes.

Long-Term Outcomes of Living Donor Versus Deceased Donor Liver Transplant for Hepatocellular Carcinoma in the United States.

OBJECTIVES: Although living donor liver transplant has become a vital treatment option in hepatocellular carcinoma, controversy remains on whether recurrence and survival rates are different versus deceased donor recipients. Here, we compared clinical characteristics and outcomes between recipients of living and deceased donor liver transplants for hepatocellular carcinoma in the United States. MATERIALS AND METHODS: Our comparisons used data from the United Network of Organ Sharing/Organ Procurement and Transplantation Network. RESULTS: There were 385 living donor and 25 274 deceased donor liver transplant recipients with diagnosis of hepatocellular carcinoma. Transplant list wait times of ≥6 months were more common in deceased donor(55.9%) versus living donor recipients (45.2%; P < .001). Both recipient groups were comparable with regard to alpha-fetoprotein level <200 ng/mL (P = .18). Only a small percentage in both groups had ≥3 total tumors (P = .73); both groups had similar low transplants outside of Milan criteria (P = .45). Overall, 1-, 5-, and 10-year overall survival rates for deceased versus living donor recipients were similar (91.2% vs 92%, 74% vs 76.4%, 58.9% vs 56.5%; P = .69). On multivariate analysis, Black/African American race/ethnicity was associated with worse outcomes than White race/ethnicity as reference (P < .001), whereas Hispanic and Asian race/ethnicity were more protected. Hepatitis C virus as liver disease etiology was associated with worse outcomes than other etiologies. Tumor characteristics, ≥3 lesions, tumor size, and higher alpha-fetoprotein levels were associated with worse outcomes. Living donor transplant was not associated with higher hazard of death. Among living donor recipients only, largest tumor size was associated with higher risk of death (P = .005). CONCLUSIONS: Survival was similarin between the living donor versus deceased donor recipients with hepatocellular carcinoma. With changes in Model for End-Stage Liver Disease exception policies for hepatocellular carcinoma in the United States, living donor transplant for hepatocellular carcinoma could expand the donor pool.

In-Hospital Mortality and Morbidity in Cancer Patients with COVID-19: A Nationwide Analysis from the United States.

Background: Coronavirus disease 2019 (COVID-19) caused significant mortality and mortality worldwide. There is limited information describing the outcomes of COVID-19 in cancer patients. Methods: We utilized the Healthcare Cost and Utilization Project Nationwide Inpatient Sample (NIS) 2020 database to collect information on cancer patients hospitalized for COVID-19 in the United States. Using the International Classification of Diseases, 10th revision, Clinical Modification (ICD-10-CM) coding system, adult (≥18 years) patients with COVID-19 were identified. Adjusted analyses were performed to assess for mortality, morbidity, and resource utilization among cancer patients. Results: A total of 1,050,045 patients were included. Of them, 27,760 had underlying cancer. Cancer patients were older and had more comorbidities. The all-cause in-hospital mortality rate in cancer patients was 17.58% vs. 11% in non-cancer. After adjusted logistic regression, cancer patients had a 21% increase in the odds of all-cause in-hospital mortality compared with those without cancer (adjusted odds ratio (aOR) 1.21, 95%CI 1.12−1.31, p-value < 0.001). Additionally, an increased odds in acute respiratory failure rate was found (aOR 1.14, 95%CI 1.06−1.22, p-value < 0.001). However, no significant differences were found in the odds of septic shock, acute respiratory distress syndrome, and mechanical ventilation between the two groups. Additionally, no significant differences in the mean length of hospital stay and the total hospitalization charges between cancer and non-cancer patients. Conclusion: Cancer patients hospitalized for COVID-19 had increased odds of all-cause in hospital mortality and acute respiratory failure compared with non-cancer patients.

The utility of CD83, fascin and CD23 in the differential diagnosis of primary mediastinal large B-cell lymphoma versus classic Hodgkin lymphoma.

Primary mediastinal large B-cell lymphoma (PMBL) and classic Hodgkin lymphoma (CHL) are the most common large cell lymphomas arising in the mediastinum and are thought to be closely related histogenetically. Although the distinction between PMBL and CHL is usually straightforward, in some cases it is challenging and rarely these neoplasms have intermediate features and qualify for the diagnosis of mediastinal gray zone lymphoma (GZL). CD83 and fascin are markers of CHL and CD23 is a marker of PMBL. In this study we assess the utility of this combination of these immunohistochemical markers to distinguish CHL from PMBL. We retrospectively collected cases of PMBL, CHL and GZL from three centers. Tissue sections were stained with CD83, fascin and CD23. CD83 was expressed in the neoplastic cells of 100% of CHL (22/22), 93% of GZL (16/18) and 41% of PMBL (9/22). Similarly, fascin was positive in the neoplastic cells of 100% of CHL (22/22), 86% of GZL (18/21) and 32% of PMBL (7/22). CD23 was positive in 95% of PMBL (21/22), 67% of GZL (12/18) and 9% of CHL (2/22). CD83 and fascin are sensitive markers for CHL but not specific whereas CD23 is sensitive for PMBL and uncommon in CHL. The GZL cases in this study had an intermediate immunophenotype, but the results were closer to CHL than PMBL. A large panel of immunohistochemical studies is recommended to distinguish CHL from PMBL entities and we suggest that CD83, fascin and CD23 add value to panels designed for this differential diagnosis.

Comparison of 22C3 PharmDx and SP263 Assays to Test PD-L1 Expression in NSCLC.

Immunohistochemical assays for programmed cell death ligand 1 (PD-L1) expression in non-small cell lung cancer (NSCLC) are either required or recommended to guide therapy with immune checkpoint inhibitors. Four commercially available immunohistochemical assays are currently available as either complimentary or companion diagnostic assay for their counterpart therapy. Harmonization or exchangeability of one assay for the other is a highly sought for goal. The aim of this study was to compare one assay, 22C3, with another, SP263, and examine whether they can be exchanged one for the other. Seventy samples from 70 patients with NSCLC were tested for PD-L1 using the SP263 and then the 22C3 antibody clones according to the manufacturer's instructions in case of the SP263 assay and according to a previously described and reported method for the 22C3 assay on the Ventana's ultra immunstainer. Results were evaluable in 51 cases, which were interpreted independently by 2 different pathologists on 2 different occasions for each case. The cases were given a percentage score based on the tumor proportion score. The Pearson correlation coefficient was calculated. A high concordance rate was found between the 2 assays. The Pearson correlation coefficient was 0.95, which indicates an almost perfect correlation (95% confidence limits, 0.92-0.97 and P<0.0001). The findings indicate that SP263 assay can be used in place of the 22C3 assay for PD-L1 assay in NSCLC, and it can be used on the Ventana platform.
