Outcomes of therapeutic plasma exchange in severe autoimmune hemolytic anemia hospitalizations: An analysis of the National Inpatient Sample.

BACKGROUND: Autoimmune hemolytic anemia (AIHA) is characterized by humoral and/or cellular immune-mediated hemolysis of red blood cells. The role of therapeutic plasma exchange (TPE) in AIHA is unclear. STUDY DESIGN AND METHODS: We queried the National Inpatient Sample (NIS) for 2002-2019 to identify hospitalizations with the primary diagnosis of AIHA. We included hospitalizations with the highest severity subclass identified by All Patient Refined Disease Related Group (APR-DRG). We used multivariate regression analysis to compare in-hospital mortality and other relevant in-hospital outcomes between hospitalizations that received TPE and those that did not. RESULTS: We identified 255 weighted hospitalizations in the TPE group and 4973 in the control group. Those in the control group were older (median age 67 vs. 48 years, p < .001) and had a higher prevalence of most comorbidities. The TPE group had higher odds of all-cause in-hospital mortality (odds ratio [OR], 1.59; 95% confidence interval [CI], 1.19-2.11). They also had higher rates of many secondary outcomes, including requiring mechanical ventilation, developing circulatory shock, acute stroke, urinary tract infections, intracranial hemorrhage, acute kidney injury, and requiring new hemodialysis. No significant differences were noted in the rates of acute myocardial infarctions, bacterial pneumonia, sepsis/septicemia, thromboembolic events, and other bleeding events. Furthermore, the TPE group had a higher median length of hospital stay (19 vs. 9 days, p < .001). CONCLUSION: Hospitalizations with severe AIHA that received TPE had higher rates of adverse in-hospital outcomes.

Utility of rapid atrial pacing before and after TAVR with balloon-expandable valve in predicting permanent pacemaker implantation.

BACKGROUND: High-grade or complete atrioventricular block (AVB) requiring permanent pacemaker (PPM) implantation is a known complication of transcatheter aortic valve replacement (TAVR). Wenckebach AVB induced by rapid atrial pacing (RAP) after TAVR was previously demonstrated in an observational analysis to be an independent predictor for PPM. We sought to investigate the utility of both pre- and post-TAVR RAP in predicting PPM implantation. METHODS: In a single-center, prospective study, 421 patients underwent TAVR with balloon-expandable valves (BEV) between April 2020 and August 2021. Intraprocedural RAP was performed in patients without a pre-existing pacemaker, atrial fibrillation/flutter, or intraprocedural complete AVB to assess for RAP-induced Wenckebach AVB. The primary outcome was PPM within 30 days after TAVR. RESULTS: RAP was performed in 253 patients, of whom 91.3% underwent post-TAVR RAP and 61.2% underwent pre-TAVR RAP. The overall PPM implantation rate at 30 days was 9.9%. Although there was a numerically higher rate of PPM at 30 days in patients with RAP-induced Wenckebach AVB, it did not reach statistical significance (13.3% vs. 8.4%, p = 0.23). In a multivariable analysis, RAP-induced Wenckebach was not an independent predictor for PPM implantation at 30 days after TAVR. PPM rates at 30 days were comparable in patients with or without pre-TAVR pacing-induced Wenckebach AVB (11.8% vs. 8.2%, p = 0.51) and post-TAVR pacing-induced Wenckebach AVB (10.2% vs. 5.8%, p = 0.25). CONCLUSION: In patients who underwent TAVR with BEV, there were no statistically significant differences in PPM implantation rates at 30 days regardless of the presence or absence of RAP-induced Wenckebach AVB. Due to conflicting results between the present study and the prior observational analysis, future studies with larger sample sizes are warranted to determine the role of RAP during TAVR as a risk-stratification tool for significant AVB requiring PPM after TAVR.

Shocked to death: a case report of cardiogenic shock and death following electrocardioversion for atrial fibrillation.

BACKGROUND: Atrial fibrillation (AF) is prevalent, especially in patients with heart failure. Their prevalence increases with age and both conditions are interrelated. Electrocardioversion (ECV) is considered a safe and effective procedure and is among one of the recommended therapies to terminate AF back to normal sinus rhythm. Our study highlights one of the rare complications following ECV. A 71-year-old female with a history of atrial fibrillation underwent electrocardioversion and developed sudden onset of ventricular stunning resulting in refractory cardiogenic shock. She was treated with mechanical cardiac support including IABP and Impella. Both provided minimal support then rapid clinical deterioration happened leading to imminent death. CONCLUSION: Patients with atrial fibrillation and heart failure treated with electrocardioversion might develop refractory cardiogenic shock and death as a complication of this procedure.

COVID-19 Infection Is Associated With Increased In-Hospital Mortality and Complications in Patients With Acute Heart Failure: Insight From National Inpatient Sample (2020).

Introduction: Patients with acute heart failure (AHF) exacerbation are susceptible to complications in the setting of COVID-19 infection. Data regarding the clinical outcomes of COVID-19 in patients admitted with AHF is limited. Methods: We used the national inpatient sample database by utilizing ICD-10 codes to identify all hospitalizations with a diagnosis of AHF in 2020. We classified the sample into AHF with COVID-19 infection versus those without COVID-19. Primary outcome was in-hospital mortality. Secondary outcomes were acute myocardial infarction, need for pressors, mechanical cardiac support, cardiogenic shock, and cardiac arrest. Also, we evaluated for acute pulmonary embolism (PE), bacterial pneumonia, need for a ventilator, and acute kidney injury (AKI). Results: We identified a total of 694,920 of AHF hospitalizations, 660,463 (95.04%) patients without COVID-19 and 34,457 (4.96%) with COVID-19 infection. For baseline comorbidities, diabetes mellitus, chronic heart failure, ESRD, and coagulopathy were significantly higher among AHF patients with COVID-19 (P < .01). While CAD, prior MI, percutaneous coronary intervention, and coronary artery bypass graft, atrial fibrillation, chronic obstructive pulmonary disease, and peripheral vascular disease were higher among those without COVID-19. After adjustment for baseline comorbidities, in-hospital mortality (aOR 5.08 [4.81 to 5.36]), septic shock (aOR 2.54 [2.40 to 2.70]), PE (aOR 1.75 [1.57 to 1.94]), and AKI (aOR 1.33 [1.30 to 1.37]) were significantly higher among AHF with COVID-19 patients. The mean length of stay (5 vs 7 days, P < .01) and costs of hospitalization ($42,143 vs $60,251, P < .01) were higher among AHF patients with COVID-19 infection. Conclusion: COVID-19 infection in patients with AHF is associated with significantly higher in-hospital mortality, need for mechanical ventilation, septic shock, and AKI along with higher resource utilization. Predictors for mortality in AHF patients during the COVID-19 pandemic, COVID-19 infection, patients with end-stage heart failure, and atrial fibrillation. Studies on the impact of vaccination against COVID-19 in AHF patients are needed.

Effect of caloric intake and macronutrient composition on intestinal cholesterol absorption and bile acids in patients with obesity.

Obesity is associated with alterations in cholesterol and bile acid (BA) metabolism. However, the interaction among dietary intake, cholesterol absorption, and BA metabolism in patients with obesity remains unclear. We conducted a 4-wk nutritional intervention nonrandomized clinical trial with three different sequential diets for a week in the following order: regular diet (RD); high calorie, high-fat diet (HCHF), washout period on RD; and low-calorie, low-fat diet (LCLF). We provided participants with meal replacements during HCHF and LCLF diets. A total of 16 participants completed the study [n = 8 normal weight (NW); n = 8 with obesity (OB)]. Overall, there was a significant increase in intestinal cholesterol uptake when changing from RD to HCHF and a reduction in intestinal cholesterol uptake from HCHF to LCLF. When analyzing by BMI groups, these findings were similar in patients with NW (RD to HCHF: P < 0.007; HCHF to LCLF: P = 0.02); however, in patients with obesity, the change in intestinal cholesterol uptake was only observed when changing from RD to HCHF (P = 0.006). There was no correlation between cholesterol absorption and fecal bile acids or other markers of BA metabolism in all patients or the subgroups. Dietary caloric content had a significant effect on cholesterol absorption, however, this effect is blunted in patients with obesity. These data are consistent with the impaired effect of a low-fat diet on cholesterol absorption in obesity.NEW & NOTEWORTHY We show how switching from a regular diet to an HCHF increases cholesterol absorption in patients with normal weight and obesity. The decrease in cholesterol absorption from an HCHF to an LCLF, on the other hand, was only seen in normal-weight controls, underlining the importance of body weight in this regulation. In addition, changes in caloric and fat content had an immediate and direct effect on hepatic bile acid production.

Management of Obesity and Nonalcoholic Fatty Liver Disease: A Literature Review.

With the recent urbanization and globalization, the adult obesity rate has been increasing, which was paralleled with a dramatic surge in the incidence and prevalence of nonalcoholic fatty liver disease (NAFLD). NAFLD poses a growing threat to human health as it represents the most common cause of chronic liver disease in developed countries. It encompasses a wide spectrum of conditions starting from a build-up of fat in hepatocytes (steatosis), to developing inflammation (steatohepatitis), and reaching up to cirrhosis. It is also associated with higher rates of cardiovascular mortalities. Therefore, proper timely treatment is essential and weight loss remains the cornerstone in the treatment of obesity-related liver diseases. When diet, exercise, and lifestyle changes are not successful, the current recommendation for weight loss includes antiobesity medications and bariatric endoscopic and surgical interventions. These interventions have shown to result in significant weight loss and improve liver steatosis and fibrosis. In the current literature review, we highlight the expected outcomes and side effects of the currently existing options to have a weight-centric NAFLD approach.

A Medical Resident's Dilemma: Clinical Proficiency vs Research Publication.

There is a delicate balance between maintaining clinical proficiency and building a robust research portfolio, emphasizing the unique struggles encountered by individuals in similar situations. Throughout my residency journey, I have navigated the intricate path of managing the demands of medical education, clinical responsibilities, and research pursuits.

Should primary care physicians consult on their admitted patients? A single-center survey study.

Background: With the rise of hospital medicine, care has become fragmented between inpatient and outpatient settings. Having primary care physicians (PCPs) consult on their admitted patients through televisits could improve patient and hospital outcomes, but perspectives on this model are unknown in adult hospital medicine. Methods: A single-center cross-sectional survey was conducted to compare PCP and hospitalist attitudes regarding PCP telemedicine consultation for admitted patients in a large US academic hospital. Results: A total of 120 participants (52 hospitalists and 68 PCPs) responded to the survey. Most hospitalists believed that their patients would benefit from PCP consultation, with 45.8% believing it was slightly important, 18.8% moderately important, and 22.9% quite important. The level of importance did not seem to influence the effort required, as most hospitalists would put in only a little effort (35.4%) to obtain a PCP consultation. PCPs were more inclined to consult on their admitted patients; 18.6% considered it slightly important to obtain their consultation, 35.6% believed it was moderately important, and 23.7% believed it was quite important. PCPs were willing to put more effort into setting up a PCP consultation (some effort, 45.8%) vs hospitalists (little effort, 35.4%). The most common challenge perceived by both groups was time commitment (hospitalists, 78.8%; PCPs, 75.0%). Conclusions: Both hospitalists and PCPs agree that a PCP consultation would benefit the patient's medical care in specific situations. However, views on the importance and frequency of PCP consultations vary between the two groups.

Impact of COVID-19 pandemic on the volume, cost, and outcomes of cardiac electrophysiology procedures in the United States.

BACKGROUND: During the COVID-19 pandemic, professional societies recommended deferral of elective procedures for optimal resource utilization. OBJECTIVE: We sought to assess changes in procedural trends and outcomes of electrophysiology (EP) procedures during the pandemic. METHODS: National Inpatient Sample databases were used to identify all EP procedures performed in the United States (2016-2020) by International Classification of Diseases, Tenth Revision codes. We evaluated trends in utilization, cost/revenue, and outcomes from EP procedures performed. RESULTS: An estimated 1.35 million EP procedures (82% devices and 18% catheter ablations) were performed (2016-2020) with significant yearly uptrend. During the pandemic, there was a substantial decline in EP procedure utilization from a 5-year peak of 298 cases/million population in the second quarter of 2019 to a nadir of 220 cases in the second quarter of 2020. In 2020, the pandemic was associated with the loss of 50,233 projected EP procedures (39,337 devices and 10,896 ablations) with subsequent revenue loss of $7.06 billion. This deficit was driven by revenue deficit from dual-chamber permanent pacemaker (PPM) utilization ($2.88 billion, 49.3% of lost cases), ablation procedures ($1.84 billion, 21.7% of lost cases), and implantable cardioverter-defibrillator implantation ($1.36 billion, 12.0% of lost cases). To the contrary, there was a 9.4% increase in the utilization of leadless PPM. EP device implantation during the pandemic was associated with higher adverse in-hospital events (9.4% vs 8.0%; P < .001). CONCLUSION: In the United States, the significant decline in EP procedures during the pandemic was primarily driven by the reduction in dual-chamber PPM utilization, followed by arrhythmia ablation and implantable cardioverter-defibrillator implantation. There was a substantial increase in leadless PPM utilization during the pandemic.

Trends of primary liver cancer incidence and mortality in the United States: A population-based study over the last four decades.

BACKGROUND: Primary liver cancer is the third leading cause of cancer deaths worldwide and has one of the worst 5-year survival rates. This study examines US primary liver cancer incidence and incidence-based mortality trends over four decades. RESEARCH DESIGN AND METHODS: The SEER-9 registry was used to study primary liver cancer cases from 1978 to 2018. The incidence and mortality rates were calculated based on gender, age, race, and stage of diagnosis. Joinpoint regression software was used to calculate the annual percent change. RESULTS: The overall incidence rate of primary liver cancer from 1978 to 2018 increased by 2.71%/year (p<0.001). Rates in patients <50 years old began to fall in 2002 at a rate of -3.62%/year (p<0.001). Similarly, the incidence-based mortality rates for primary liver cancer increased by 2.15%/year (p<0.001). Whereas Whites incidence-based mortality rates began to plateau in 2012 (0.18%/year; p = 0.84), Blacks rates have declined since 2010 (-2.93%/year; p = 0.03), and Asian rates have declined since 1999 (-1.30%/year; p<0.001). CONCLUSION: While the overall primary liver cancer incidence and incidence-based mortality have been increasing over the last four decades, there was an observed decline in incidence and incidence-based mortality in recent years, especially among at-risk subgroups.

Trends and Outcomes of Acute Myocardial Infarction During the Early COVID-19 Pandemic in the United States: A National Inpatient Sample Study.

BACKGROUND AND OBJECTIVES: There are limited national data on the trends and outcomes of patients hospitalized with acute myocardial infarction (AMI) during the coronavirus disease 2019 (COVID-19) pandemic. We aimed to evaluate the impact of early COVID-19 pandemic on the trends and outcomes of AMI using the National Inpatient Sample (NIS) database. METHODS: The NIS database was queried from January 2019 to December 2020 to identify adult (age ≥18 years) AMI hospitalizations and were categorized into ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction (NSTEMI) based on International Classification of Diseases, Tenth Revision, Clinical Modification codes. In addition, the in-hospital mortality, revascularization, and resource utilization of AMI hospitalizations early in the COVID-19 pandemic (2020) were compared to those in the pre-pandemic period (2019) using multivariate logistic and linear regression analysis. RESULTS: Amongst 1,709,480 AMI hospitalizations, 209,450 STEMI and 677,355 NSTEMI occurred in 2019 while 196,230 STEMI and 626,445 NSTEMI hospitalizations occurred in 2020. Compared with those in 2019, the AMI hospitalizations in 2020 had higher odds of in-hospital mortality (adjusted odds ratio [aOR], 1.27; 95% confidence interval [CI], [1.23-1.32]; p<0.01) and lower odds of percutaneous coronary intervention (aOR, 0.95 [0.92-0.99]; p=0.02), and coronary artery bypass graft (aOR, 0.90 [0.85-0.97]; p<0.01). CONCLUSIONS: We found a significant decline in AMI hospitalizations and use of revascularization, with higher in-hospital mortality, during the early COVID-19 pandemic period (2020) compared with the pre-pandemic period (2019). Further research into the factors associated with increased mortality could help with preparedness in future pandemics.

Rates and Predictors of Structural Valve Degeneration and Failure of Trifecta Bioprosthetic Valve Over a 5-year Follow-up Period: A Single-center Experience.

Introduction: The Trifecta bioprosthetic valve has been commonly used for surgical aortic valve replacement (SAVR). Multiple studies have been done to define the rate of structural valve degeneration (SVD) and failure (SVF), but the outcomes are still debatable. Therefore, we aim to conduct this single-center study to estimate the rate and predictors of SVD/SVF. Methodology: This retrospective observational cohort single-center study was conducted between 2014 and 2019 among Trifecta SAVR patients. Data were patient's characteristics collected from electronic medical records at baseline and follow-up (3-5 years). Statistical analysis was performed with a significance level of P ≤ 0.05. Results: A total of 271 eligible patients were identified. Most of our sample were males (57.9%), with a mean age of 71.1 ± 10.6 years. The mean baseline preoperative ejection fraction (EF) was 53.0%, with no change (P = 0.88) in the immediate postoperative EF (53.6%). A most recent follow-up EF revealed a significant increase of EF (55.2%), P = 0.01. Furthermore, there was a significant increase from peak velocity to PVMRE (mean difference [MD] ± standard error of mean (SEM) [0.15 ± 0.04], P < 0.01), an increase in pressure gradient (PGIPE) to PGMRE (MD ± SEM [1.70 ± 0.49], P < 0.01), and a decrease in Doppler velocity index (DVIIPE) to DVIMRE (MD ± SEM [-0.037 ± 0.01], P = 0.01). Regarding the SVF rate, 13 (4.8%) patients had failed valves requiring replacement throughout the study period. Conclusions: Over a 5-year follow-up period, 4.8% had SVF with an SVD of 23.2%, with the majority of SVD not being clinically significant except in six patients. These results corroborate with a previously published study suggesting a bad clinical outcome of Trifecta valve placement.

Racial, ethnic and sex disparity in acute heart failure patients with COVID-19: A nationwide analysis.

Background: Patients with acute heart failure (AHF) exacerbation are susceptible to complications in the setting of COVID-19 infection. Data regarding the racial/ethnic and sex disparities in patients with AHF and COVID-19 remains limited. Objective: We aim to evaluate the impact of race, ethnicity, and sex on the in-hospital outcomes of AHF with COVID-19 infection using the data from the National Inpatient Sample (NIS). Methods: We extracted data from the NIS (2020) by using ICD-10-CM to identify all hospitalizations with a diagnosis of AHF and COVID-19 in the year 2020. The associations between sex, race/ethnicity, and outcomes were examined using a multivariable logistic regression model. Results: We identified a total of 158,530 weighted AHF hospitalizations with COVID-19 infection in 2020. The majority were White (63.9 %), 23.3 % were Black race, and 12.8 % were of Hispanic ethnicity, mostly males (n = 84,870 [53.5 %]). After adjustment, the odds of in-hospital mortality were lowest in White females (aOR 0.83, [0.78-0.98]) and highest in Hispanic males (aOR 1.27 [1.13-1.42]) compared with White males. Overall, the odds of cardiac arrest (aOR 1.54 [1.27-1.85]) and AKI (aOR 1.36 [1.26-1.47] were higher, while odds for procedural interventions such as PCI (aOR 0.23 [0.10-0.55]), and placement on a ventilator (aOR 0.85 [0.75-0.97]) were lower among Black males in comparison to White males. Conclusion: Male sex was associated with a higher risk of in-hospital mortality in white and black racial groups, while no such association was noted in the Hispanic group. Hispanic males had the highest odds of death compared with White males.

Early vs. late transcatheter aortic valve replacement in acute heart failure hospitalizations: A comparative nationwide analysis.

BACKGROUND: Severe aortic stenosis (AS) is the most common valvular disease in the USA. Patients undergoing urgent or emergent transcatheter aortic valve replacement (TAVR) have worse clinical outcomes than those undergoing non-urgent procedures. No studies have examined the impact of procedural TAVR timing on outcomes in AS complicated by acute heart failure (AHF). AIMS: We aimed to evaluate differences in in-hospital mortality and clinical outcomes between early (<48 h) vs. late (≥48 h) TAVR in patients hospitalized with AHF using a real-world US database. METHODS: We queried the National Inpatient Sample database to identify hospitalizations with a diagnosis of AHF, aortic valve disease, and a TAVR procedure (2015-2020). The associations between TAVR timing and clinical outcomes were examined using logistic regression model. RESULTS: A total of 25,290 weighted AHF hospitalizations were identified, of which 6855 patients (27.1 %) underwent early TAVR, and 18,435 (72.9 %) late TAVR. Late TAVR patients had higher in-hospital mortality rate (2.2 % vs. 2.8 %, p < 0.01) on unadjusted analysis but no significant difference following adjustment for demographic, clinical, and hospital characteristics [aOR 1.00 (0.82-1.23)]. Late TAVR was associated with higher odds of cardiac arrest (aOR 1.50, 95 % CI: 1.18-1.90) and use of mechanical circulatory support (aOR 2.05, 95 % CI: 1.68-2.51). Late TAVR was associated with longer hospital stay (11 days vs. 4 days, p < 0.01) and higher costs ($72,851 vs. $53,209, p < 0.01). CONCLUSION: Early TAVR was conducted in approximately 25 % of the AS patients admitted with AHF, showing improved in-hospital outcomes before adjustment, with no significant differences observed after adjustment.

Higher body mass index is strongly linked to poor outcomes in adult COVID-19 hospitalizations: A National Inpatient Sample Study.

Aims: The coronavirus disease 2019 (COVID-19) pandemic has resulted in more than 6 million deaths worldwide. Studies on the impact of obesity on patients hospitalized with COVID-19 pneumonia have been conflicting, with some studies describing worse outcomes in patients with obesity, while other studies reporting no difference in outcomes. Previous studies on obesity and critical illness have described improved outcomes in patients with obesity, termed the "obesity paradox." The study assessed the impact of obesity on the outcomes of COVID-19 hospitalizations, using a nationally representative database. Materials and Methods: ICD-10 code U071 was used to identify all hospitalizations with the principal diagnosis of COVID-19 infection in the National Inpatient Database 2020. ICD-10 codes were used to identify outcomes and comorbidities. Hospitalizations were grouped based on body mass index (BMI). Multivariable logistic regression was used to adjust for demographic characteristics and comorbidities. Results: A total of 56,033 hospitalizations were identified. 48% were male, 49% were white and 22% were black. Patients hospitalized with COVID-19 pneumonia in the setting of obesity and clinically severe obesity were often younger. Adjusted for differences in comorbidities, there was a significant increase in mortality, incidence of mechanical ventilation, shock, and sepsis with increased BMI. The mortality was highest among hospitalizations with BMI ≥60, with an adjusted odds ratio of 2.66 (95% Confidence interval 2.18-3.24) compared to hospitalizations with normal BMI. There were increased odds of mechanical ventilation across all BMI groups above normal, with the odds of mechanical ventilation increasing with increasing BMI. Conclusion: The results show that obesity is independently associated with worse patient outcomes in COVID-19 hospitalizations and is associated with higher in-patient mortality and higher rates of mechanical ventilation. The underlying mechanism of this is unclear, and further studies are needed to investigate the cause of this.

Feasibility and Safety of Intracardiac Echocardiography Guidance in Mitral Transcatheter Edge-to-Edge Repair: Analysis of the National Inpatient Sample Data From 2015 to 2020.

Data on the use of intracardiac echocardiography (ICE) guidance in mitral transcatheter edge-to-edge repair (mTEER) procedure is limited to case reports and small case series. Our study aims to assess the feasibility, safety, utilization patterns, and clinical outcomes of mTEER procedure with ICE guidance using a nationally representative real-world cohort of patients. This study used the National Inpatient Sample database from quarter 4 of 2015 to 2020. We used a propensity-matched analysis and adjusted odds ratios for in-hospital outcomes/complications. A P value of < 0.05 was considered significant. A total of 38,770 weighted cases of mTEER were identified. Of the included patients 665 patients underwent ICE-guided mTEER while 38,105 had TEE-guided mTEER. There were no differences in the in-hospital mortality between both groups (2.5% vs 3.0%, P = 0.58). Adjusted odds of in-hospital mortality (aOR 0.83, 95%CI [0.42-1.64]) were not significantly different. There were no differences in periprocedural complications including cardiac (aOR 0.85, 95%CI [0.54-1.35]), bleeding (aOR 1.45, 95%CI [0.93-2.33]), respiratory (aOR 0.88, 95%CI [0.61-1.25]), and renal (aOR 0.89, 95%CI [0.66-1.20]) complications between patients undergoing ICE-guided vs TEE-guided mTEER. There was no difference in GI complications between both groups (aOR 1.11, 95%CI [0.46-2.70]). The adjusted length of stay was less among ICE-guided mTEER (median: 1 vs 2, P < 0.01) with lower inflation-adjusted costs of hospitalization ($35,513 vs $47,067, P < 0.01). ICE-guided mTEER is safe when compared with TEE guided mTEER with no significant differences in in-hospital mortality, cardiac, bleeding, respiratory, and renal complications.

Atypical Peutz-Jeghers Syndrome Presenting With a Huge Jejunojejunal Intussusception in a Young Male: A Case Report.

Intussusception is considered one of the rare causes of intestinal obstruction in adults compared to pediatric patients. It usually presents with non-specific clinical manifestations ranging from mild recurrent abdominal pain to severe acute abdominal pain. The non-specificity of its symptoms makes it difficult to diagnose preoperatively. As 90% of adult intussusceptions are due to a pathological lead point, this prompts the underlying medical condition to be identified. We herein report a rare case of a 21-year-old male with atypical clinical features of Peutz-Jegher syndrome (PJS), presenting with jejunojejunal intussusception as a result of a hamartomatous intestinal polyp. A preliminary diagnosis of intussusception was made after an abdominal computed tomography (CT) scan and was confirmed intraoperatively. Postoperatively, the patient's condition improved steadily, and he was discharged with a referral to the gastroenterologist for further assessment.

Cardiac Arrest Secondary to Inferior ST-Segment-Elevation Myocardial Infarction in Patient with Paroxysmal Nocturnal Hemoglobinuria and COVID-19 Infection.

Patients with paroxysmal nocturnal hemoglobinuria (PNH) have transient attacks of complement-mediated hemolysis and thrombosis that can be spontaneous or secondary to precipitating factors such as infections. We present a case of a 63-year-old male patient with a medical history of PNH who presented with typical chest pain, fever, cough, jaundice, and dark-colored urine. On examination, he was hemodynamically stable but had conjunctival icterus. A few minutes after presentation, the patient suffered a ventricular fibrillation cardiac arrest and then achieved a return of spontaneous circulation after receiving two defibrillator shocks. EKG showed inferior wall ST-segment elevation myocardial infarction. Labs showed hemoglobin of 6.4 g/dl, elevated cardiac markers, serum lactate dehydrogenase, and indirect bilirubin. Serum haptoglobin was < 1 mg/dl. His COVID-19 polymerase chain reaction test was positive. Immediately, the patient received 2 units of packed RBCs and underwent a coronary angiogram (CA), which revealed total proximal occlusion of the right coronary artery. He underwent successful percutaneous coronary intervention (PCI), and two drug-eluting stents were placed. His peripheral blood immunophenotyping and flow cytometry showed loss of glycosylphosphatidylinositol-linked antigens and decreased expression of CD 59/14/24. He was started on ravulizumab, a humanized monoclonal antibody complement five inhibitor. Both PNH and COVID-19 increase the risk of thrombosis. Endothelial injury and cytokine storm increase the risk of thrombosis in COVID-19 patients, whereas the activation of the coagulation system and the impairment of the fibrinolytic system by complement cascade leads to thrombosis in PNH patients. Regardless of which pathway leads to coronary artery thrombosis, CA and PCI can be life-saving.

Bullous herpes zoster masquerading as a bullous pemphigoid flare: A case report.

Herpes zoster (HZ) results from the reactivation of dormant varicella zoster virus (VZV) in the posterior dorsal root ganglia manifesting as painful vesicles along the dermatomal distribution as shingles. The risk of reactivation is higher in immunocompromised patients. Herpes zoster lesions can have varied presentations including bullous forms, may induce BP flare, may co-exist in the same lesions, and should be included in the list of differentials for BP flares not responding to the standard of care. Here, we describe a case of a 74-year-old female with a history of recurrent bullous pemphigoid (BP) flares, who was on mycophenolate mofetil, and presented with skin lesions on her right thigh which were typical for her BP flares. Unlike prior flares, the lesions did not respond to prednisone therapy. Her hospitalization course was complicated by encephalopathy. Intravenous acyclovir was started empirically. Viral cultures and polymerase chain reaction from the lesions came back positive for VZV, but the patient succumbed to her illness shortly afterward.
