Objective: Cardiac arrest can complicate infective endocarditis (IE) and is associated with significant in-hospital complications and mortality rates. We report the characteristics, outcomes, and readmission rates for IE patients with cardiac arrest in the United States., Methods: We surveyed the Nationwide Readmission Database (NRD), a database designed to support national level readmission analyses, for patients admitted with IE and who had cardiac arrest during index admission between 2016 and 2019. Baseline demographics, comorbidities, surgical procedures, and outcomes were identified using their respective International Classification of Diseases (ICD) codes., Results: There were 663 index admissions (mean age 55.87 ± 17.21 years;34.2 % females) for IE with cardiac arrest in the study period, with an overall mortality rate of 55.3 %. Of these, 270 (40.7 %) had surgical procedures performed during the hospitalization encounter. In patients who had a surgical procedure, 72 (26.8 %) patients had in-hospital mortality while 293 (74.9 %) patients without surgical procedures had in-hospital mortality (p < 0.001). After coarsened matching for baseline characteristics, surgical valve procedures were less likely to be associated with mortality (OR = 0.09, 95%CI 0.04-0.24; p < 0.001). Among the 295 alive discharges associated with cardiac arrest, 76 (38.57 %) were readmitted within 30-days, with a mortality rate of 22 % noted for readmissions., Conclusion: Among IE patients who had cardiac arrest, surgical procedures subgroup had low mortality despite having higher complication rates. However, due to chances of bias more randomized trials are needed evaluate the hypothesis., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.

Background: Literature regarding outcomes of cardiorenal syndrome (CRS) among heart failure with reduced ejection fraction (HFrEF) is limited., Objective: To study the clinical outcomes and 30-day readmission rates of CRS patients with HFrEF., Methods: Data from the Nationwide Readmissions Database (NRD) that constitutes 49.1% of the stratified sample of all hospitals in the United States (US), representing >95% of the national population, was analyzed for the CRS with HFrEF visits from 2018 to 2019. CRS was defined by the ICD-10 codes., Results: Out of the 1,530,749 index CRS-related hospitalizations (mean age:64.37 ± 13.30 years; 38.6%females) 73,126 (6.0%) CKD I-II, 883,119 (72.6%) CKD III-IV, and 258,835 (21.3%) CKD V-and-more related encounters were recorded. Mortality was higher among CKD stage V-and-more in comparison to other subgroups(7.6%vs5.73%;p < 0.001). AKI with underlying CKD was more common among stage III-IV compared to other subgroups (55.9%vs43.7%;p < 0.001). Respiratory failure, the second major complication, was more common among stage V-and-more compared to other subgroups (32.5%vs30%;p < 0.001). The overall CRS-related 30-day readmission rate was 22.7%, with CKD V-and-more accounting for highest rates(29.89%), followed by CKD stage III-IV(20.05%) and CKD I-II(12.99%). The primary etiology for 30-day readmission was cardiovascular among all subgroups (54.2%, 54.6%, and 41.80%, which corresponds to CKD I-II, CKD III-IV and CKD V-and-more, respectively)., Conclusion: CRS among HFrEF accounts for substantial healthcare burden with high 30-day readmission rates. Higher all-cause mortality and 30-day readmissions were associated with worse renal disease. This would suggest that more vigilance is needed by physicians for discharge planning among this patient population., (Copyright © 2022 Elsevier B.V. All rights reserved.)

Literature regarding recent trends and outcomes of acute new-onset heart failure (AHF) with preserved ejection fraction (AHFpEF) and reduced ejection fraction (AHFrEF) is limited. The objective of this study is to study the outcomes of AHFpEF and AHFrEF in the USA. Data from the National Readmissions Database (NRD) sample that constitutes 49.1% of the stratified sample of all hospitals in the USA, representing more than 95% of the national population, were analyzed for hospitalization visits for acute heart failure. ICD-9 and ICD-10 codes were used to identify AHF. A total of 2,559,102 adult index AHF patients (mean age 70.79 ± 14.58 years, 49.4% females), 1,028,970 (40.2%) AHFpEF and 1,330,999 (52%) AHFrEF, were recorded in the National Readmissions Database for the years 2016-2018. A total of 152,465 (5.96%) acute heart failure, 47,271 (4.6%) AHFpEF and 91,973 (6.91%) AHFrEF, died during hospitalization, and 45,810 (1.9%) were readmitted in 30 days among alive discharges. Higher complication rates which included ventricular arrhythmias, acute coronary, and cerebrovascular events were observed among AHFrEF than AHFpEF. Higher proportion of patients with AHFrEF needed intensive care unit and ventilatory support during the hospitalization. The trend of incidence of AHFrEF, mortality among AHFrEF, and overall mortality worsened while AHFpEF improved over the study years 2012-2018 (p-trend < 0.05). Coronary procedures improved mortality rates among AHFpEF and AHFrEF. AHF is very common and is associated with significant mortality. The incidence of AHFrEF and mortality among AHFrEF had worsened, which calls for urgent intervention. Improved recognition of AHF is needed, and guideline-directed treatment of underlying risk factors including coronary artery disease can improve mortality.

Background: Limited epidemiological data are available on the outcomes of in-hospital cardiac arrest (CA) in COVID-19 patients., Methods: We performed literature search of PubMed, EMBASE, Cochrane, and Ovid to identify research articles that studied outcomes of in-hospital cardiac arrest in COVID-19 patients. The primary outcome was survival at discharge. Secondary outcomes included return of spontaneous circulation (ROSC) and types of cardiac arrest. Pooled percentages with a 95% confidence interval (CI) were calculated for the prevalence of outcomes., Results: A total of 7,891 COVID patients were included in the study. There were 621 (pooled prevalence 8%, 95% CI 4-13%) cardiac arrest patients. There were 52 (pooled prevalence 3.0%; 95% CI 0.0-10.0%) patients that survived at the time of discharge. ROSC was achieved in 202 (pooled prevalence 39%;95% CI 21.0-59.0%) patients. Mean time to ROSC was 7.74 (95% CI 7.51-7.98) min. The commonest rhythm at the time of cardiac arrest was pulseless electrical activity (pooled prevalence 46%; 95% 13-80%), followed by asystole (pooled prevalence 40%; 95% CI 6-80%). Unstable ventricular arrhythmia occurred in a minority of patients (pooled prevalence 8%; 95% CI 4-13%)., Conclusion: This pooled analysis of studies showed that the survival post in-hospital cardiac arrest in COVID patients is dismal despite adequate ROSC obtained at the time of resuscitation. Nonshockable rhythm cardiac arrest is commoner suggesting a non-cardiac cause while cardiac related etiology is uncommon. Future studies are needed to improve the survival in these patients., (© 2021 Wiley Periodicals LLC.)

Background: Literature on bioresorbable-polymer-stents (BPS) and second-generation durable-polymer-stents (DPS) in percutaneous coronary intervention (PCI) for all comer CAD is conflicting., Methods: Randomized controlled studies comparing PCI among BPS and second-generation DPS were identified up until May-2020 from online databases.  Primary outcomes included are all-cause myocardial infarction (MI), cardiac-death, target-vessel-revascularization (TVR), target-vessel MI (TVMI), and stent-thrombosis (ST). Random effect method of risk ratio and confidence interval of 95% was used., Results: 25 prospective randomized controlled trials with 31,822 patients (BPS n = 17,065 and DPS n = 14,757) were included in the study. Follow-up ranged between a minimum of 6 months to more than 5 years. Cardiac death (RR 1.02, 95% CI 0.89-1.45, p = 0.16) was comparable in BPS and second-generation DPS. Risk of all-cause MI was similar between BPS and DPS (RR 0.97, 95% CI 0.84-1.11, p = 0.73). TVMI (RR 0.88, 95% CI 0.69-1.11, p = 0.33) and ST rates were also comparable in BPS and DPS groups (RR 1.06, 95% CI 0.80-1.40, p = 1.00). Overall TVR had comparable outcomes between BPS and DPS (RR 0.95, 95% CI 0.79-1.14, p < 0.001); however, higher TVR was seen among BPS group at follow-up of ≥5 years (RR 1.39, 95% CI 1.12-1.14, p = 0.02). Bias was low and heterogeneity was moderate., Conclusion: Patients undergoing PCI treated with BPS had comparable outcomes in terms of cardiac death, TVR, ST, TVMI, and all-cause MI to patients treated with second-generation DPS; however, BPS had higher rates of TVR for follow-up of ≥5-years.

Neuroendocrine tumors (NETs) are epithelial neoplasms with predominant neuroendocrine differentiation and the ability to synthesize and secrete variable hormones and monoamines. They are relatively rare, accounting for 2% of all malignancy cases in the United States. The most common system affected by NETs is the gastrointestinal tract. Clinical presentation depends on the organ being involved and the hormone being secreted. It can be variable from asymptomatic incidental findings on imaging to intestinal obstruction, or carcinoid syndrome (CS). Several biochemical testings are developed to help with the diagnosis of NETs including 5-hydroxyindoleacetic acid (5-HIAA) and chromogranin A (CgA). Computerized tomography (CT) scans and magnetic resonance imaging (MRI) are the most commonly used modalities to localize the primary tumor and evaluate for metastasis. However, radionuclide imaging using somatostatin receptor-based imaging techniques has improved accuracy to detect smaller neoplasm. Surgical removal is the mainstay of treatment for locoregional tumors. Several medical managements are available for non-respectable NETs which include SSAs, peptide receptor radionuclide therapy (PRRT), and platinum-based chemotherapy agents., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2021, Yazdanpanah et al.)

Esophago-pericardial fistulae is a rare and dreaded entity. Most reported cases in the literature were described in association with advanced upper gastrointestinal malignancies, prior surgical procedures, and radiofrequency atrial fibrillation ablation. It has been rarely reported in association with benign esophageal conditions. Surgery had been the mainstay of treatment, but there are increasingly reported cases treated successfully with esophageal stenting and pericardial drainage. In this article, we report a novel case of an esophago-pericardial fistulae occurring as a sequela of esophageal stent placed for the management of Boerhaave syndrome.

Atrial fibrillation (AF) is a relatively common clinical entity with significant morbidity and mortality, particularly in the elderly. Stroke is one of the most significant complications of AF, which can be prevented with the use of anticoagulation. Elder population are at an increased risk of falls and the use of anticoagulation in this group can lead to intracranial hemorrhage. Therefore, it is unclear whether patients at high risk of falls should be anticoagulated. This review article discusses the epidemiology of AF and falls in the elder population, and whether the benefit of anticoagulation outweighs the risks in this group., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2020, Shanah et al.)

Patients with primary and metastatic brain tumors are predisposed to thromboembolism. This review of the literature explores the high prevalence of venous thromboembolism and its negative impact on patients with brain cancer. It outlines the recommended prophylactic strategies to prevent venous thrombosis and analyzes the benefit versus risk of anticoagulation in this population, with a focus on the risk of intracranial bleeding associated with it. Additionally, it explores the exceedingly high prevalence of venous thromboembolism in the setting of brain cancer surgeries and provides guidance on the best methods used for prophylaxis in this setting and discusses the safety of each method perioperatively. Lastly, this review article provides guidance on how to manage venous thromboembolism in patients with brain cancer and discusses the use of vena cava filters in this population., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2020, Kabashneh et al.)

Malnutrition is extremely common in hospitalized patients. It can lead to various complications and increase mortality. However, it remains poorly recognized and many health care systems do not require nutritional assessment during the hospital stay. This most likely due to lack of awareness and inadequate coordination between health care workers. Physicians can utilize many different methods when performing malnutrition screening, and there is also a lack of global clear-cut recommendations on criteria used to diagnose malnutrition. This article aims to increase malnutrition awareness among health care providers, and provide a guide on screening, diagnosis, and management of malnutrition., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2020, Kabashneh et al.)
