Psoriasis is a chronic inflammatory state associated with an increased risk of cardiometabolic diseases, stroke, and mortality. Although psoriasis increases the risk of ischemic stroke, whether outcomes, including mortality, are adversely affected is unknown. This study aims to compare inpatient mortality of patients admitted for ischemic stroke with and without psoriasis. The secondary outcome measures were hospital length of stay (LOS), total hospital charges, odds of receiving tissue plasminogen activator (TPA), and mechanical thrombectomy between both groups. Data were obtained from the National Inpatient Sample (NIS) 2016 and 2017 databases using the International Classification of Diseases, Tenth Revision, Clinical Modification codes. Multivariable logistic and linear regression analysis were used accordingly to account for confounders of the outcomes. The combined 2016 and 2017 NIS database comprised over 71 million discharges. Of these, ischemic stroke accounted for 525,570 hospitalizations and 2425 (0.5%) had a concomitant diagnosis of psoriasis. Patients hospitalized for ischemic stroke with coexisting psoriasis did not have a difference in inpatient mortality (3.5% vs 5.5%; p=0.285) compared with those without psoriasis. However, psoriasis cohort had shorter LOS (5.0 vs 5.7 days; p=0.029) and lower total hospital charges ($60,471 vs $70,246; p=0.003) compared with the non-psoriasis cohort. The odds of receiving TPA and undergoing mechanical thrombectomy were not different in both groups. Inpatient mortality, odds of receiving TPA, and undergoing mechanical thrombectomy in patients who had an ischemic stroke with or without psoriasis were not different. However, patients with psoriasis had a significantly shorter LOS and lower hospital charges.

This study compares outcomes of patients admitted for atrial fibrillation (AF) with and without coexisting systemic lupus erythematosus (SLE). The primary outcome was inpatient mortality. Hospital length of stay (LOS), total hospital charges, odds of undergoing ablation, pharmacologic cardioversion and electrical cardioversion were secondary outcomes of interest. Data were abstracted from the National Inpatient Sample (NIS) 2016 and 2017 database. The NIS was searched for adult hospitalizations with AF as principal diagnosis with and without SLE as secondary diagnosis using International Classification of Diseases, Tenth Revision, Clinical Modification codes. Multivariate logistic and linear regression analysis was used accordingly to adjust for confounders. There were over 71 million discharges included in the combined 2016 and 2017 NIS database. 821,630 hospitalizations were for adult patients, who had a principal diagnosis of AF, out of which, 2645 (0.3%) had SLE as secondary diagnosis. Hospitalizations for AF with SLE had similar inpatient mortality (1.5% vs 0.91%, adjusted OR (AOR): 1.0, 95% CI 0.47 to 2.14, p=0.991), LOS (4.2 vs 3.4 days, p=0.525), total hospital charges ($51,351 vs $39,121, p=0.056), odds of undergoing pharmacologic cardioversion (0.38% vs 0.38%, AOR: 0.90, 95% CI 0.22 to 3.69, p=0.880) and electrical cardioversion (12.9% vs 17.5%, AOR 0.87, 95% CI 0.66 to 1.15, p=0.324) compared with those without SLE. However, SLE group had increased odds of undergoing ablation (6.8% vs 4.2%, AOR: 1.9, 95% CI 1.3 to 2.7, p

Objective This study aims to compare the outcomes of patients primarily admitted for acute coronary syndrome (ACS) with and without systemic sclerosis (SSc). The primary outcome was odds of inpatient mortality. Hospital length of stay, total hospital charges, rates of cardiovascular procedures, and treatments were secondary outcomes of interest. Methods Data were abstracted from the National Inpatient Sample (NIS) 2016 and 2017 Database. The NIS was searched for hospitalizations for adult patients with ACS (ST-segment elevation myocardial infarction [STEMI], non-ST-segment elevation myocardial infarction [NSTEMI], and unstable angina) as principal diagnosis with and without SSc as secondary diagnosis using International Classification of Diseases, Tenth Revision codes. Multivariate logistic and linear regression analysis was used accordingly to adjust for confounders. Results There were more than 71 million discharges included in the combined 2016 and 2017 NIS database. There were 1,319,464 hospitalizations for adult patients with a principal International Classification of Diseases, Tenth Revision code for ACS. There were 1155 (0.09%) of these hospitalizations that had SSc. The adjusted odds ratios for inpatient mortality for ACS, STEMI, and NSTEMI hospitalizations with coexisting SSc compared with those without SSc were 2.02 (95% confidence interval [CI], 1.19-3.43; p = 0.009), 2.47 (95% CI, 1.05-5.79; p = 0.038), and 2.19 (95% CI, 1.14-4.23; p = 0.019), respectively. Conclusions Acute coronary syndrome hospitalizations with SSc have increased inpatient mortality compared with those without SSc. ST-segment elevation myocardial infarction and NSTEMI hospitalizations with SSc have increased inpatient mortality compared with STEMI and NSTEMI hospitalizations without SSc, respectively. Acute coronary syndrome hospitalizations with SSc have similar hospital length of stay, total hospital charges, rates of revascularization strategies (percutaneous coronary intervention, coronary artery bypass surgery, and thrombolytics), and other interventions (such as percutaneous external assist device and intra-aortic balloon pump) compared with those without SSc.

Purpose The aim of this study was to compare the outcomes of patients primarily admitted for atrial fibrillation (AFib) with and without a secondary diagnosis of systemic sclerosis (SSc). The primary outcome was inpatient mortality. Hospital length of stay (LOS), total hospital charges, odds of undergoing ablation, and electrical cardioversion were secondary outcomes of interest. Methods Data were abstracted from the National Inpatient Sample (NIS) 2016 and 2017 Database. The NIS was searched for adult hospitalizations with AFib as principal diagnosis with and without SSc as secondary diagnosis using International Classification of Diseases, Tenth Revision, Clinical Modification codes. Multivariate logistic and linear regression analysis was used accordingly to adjust for confounders. Results There were over 71 million discharges included in the combined 2016 and 2017 NIS database. Of 821,630 AFib hospitalizations, 750 (0.09%) had SSc. The adjusted odds ratio for inpatient mortality for AFib with coexisting SSc compared with without coexisting SSc was 3.3 (95% confidence interval, 1.27-8.52; p = 0.014). Atrial fibrillation with coexisting SSc hospitalizations had similar LOS (4.2 vs 3.4 days; p = 0.767), mean total hospital charges ($40,809 vs $39,158; p = 0.266), odds of undergoing ablation (2.7% vs 4.2%; p = 0.461), and electrical cardioversion (12.0% vs 17.5%; p = 0.316) compared with without coexisting SSc. Conclusions Patients admitted primarily for AFib with a secondary diagnosis of SSc have more than 3 times the odds of inpatient death compared with those without coexisting SSc. Hospital LOS, total hospital charges, likelihood of undergoing ablation, and electrical cardioversion were similar in both groups.

OBJECTIVES The aims of this study were to compare the outcomes of patients primarily admitted for ischemic stroke with and without a secondary diagnosis of RA. METHODS Data were abstracted from the National Inpatient Sample (NIS) 2016 and 2017 database. The NIS was searched for hospitalizations for adult patients with ischemic stroke as principal diagnosis with and without RA as secondary diagnosis using International Classification of Diseases, 10th Revision codes. The primary outcome was inpatient mortality. Hospital length of stay (LOS), total hospital charges, odds of receiving tissue plasminogen activator, and mechanical thrombectomy were secondary outcomes of interest. Multivariate logistic and linear regression analyses were used accordingly to adjust for confounders. RESULTS There were more than 71 million discharges included in the combined 2016 and 2017 NIS database. Of 525,570 patients with ischemic stroke, 8670 (1.7%) had RA. Hospitalizations for ischemic stroke with RA had less inpatient mortality (4.7% vs. 5.5%; adjusted odds ratio, 0.66; 95% confidence interval, 0.52-0.85; p = 0.001), shorter LOS (5.1 vs 5.7 days, p < 0.0001), lower mean total hospital charges ($61,626 vs. $70,345, p < 0.0001), and less odds of undergoing mechanical thrombectomy (3.9% vs. 5.1%; adjusted odds ratio, 0.55; 95% confidence interval, 0.42-0.72; p < 0.0001) compared with those without RA. CONCLUSIONS Hospitalizations for ischemic stroke with RA had less inpatient mortality, shorter LOS, lower total hospital charges, and less likelihood of undergoing mechanical thrombectomy compared with those without RA. However, the odds of receiving tissue plasminogen activator were similar between both groups. Further studies to understand its mechanism would be helpful.

Left ventricular noncompaction (LVNC) is a relatively rare myocardial disorder which is characterized by trabeculations and deep intertrabecular recesses within the left ventricle. LVNC is often asymptomatic but may present with heart failure, arrhythmias, or systemic thromboembolism. Uncommonly, patients with LVNC can present with syncope. In this article, we report one such presentation of this rare medical condition.

Introduction: Hyperglycemic hyperosmolar state is an endocrinological emergency associated with type 2 diabetes (T2DM) patients. HHS is associated with significant morbidity and mortality. The burden of HHS, however, does not end with the index admission. This study sought to determine the rate, reasons and predictors of 30-day readmissions (30DR) in T2DM patients with index admission for HHS with the goal of identifying potentially modifiable factors to decrease the burden of readmissions. Methods: The US Readmission database for 2018 was searched for index hospitalizations involving adult patients with T2DM who had HHS in 2018. Outcomes assessed included 30DR rates, top principal diagnosis for readmitted patients, comparison of mortality, length of stay (LOS), and hospitalization costs (THC), and predictors of 30DR. Results: A total of 21,721 hospitalizations involved adults with T2DM with HHS during the index admissions. The 30DR rate was 13.77%. The most common reasons for readmission was DM type 2 with hyperglycemia (8.6%), DKA (8.1%), HHS (8.0%), sepsis unspecified (7.9%), and acute renal failure (4.2%). Readmission was associated with higher odds of mortality (2.55% vs. 0.65%, OR: 4.00, 95% CI: 2.63 - 6.07), longer LOS (5.8 vs. 3.9 days, p Conclusion: HHS is associated with significant complications following the index admission. 30DR is associated with increased mortality and healthcare utilization in this population. Proper discharge planning and addressing factors associated with readmissions would likely improve outcome in this population. Disclosure H. Shaka: None. M. C. Aguilera: None. S. T. Yap: None. M.

Introduction: Psoriasis is known to increase the risk of type 1 diabetes mellites. This study aims to compare rates and outcomes of 30-day readmissions following admissions for type 1 diabetic ketoacidosis (T1DKA) in patients with and without psoriasis in the United States. Methods: We analyzed the 2018 National Readmission Database. We included index hospitalizations for all patients (aged≥18 years) with a principal diagnosis of T1DKA using ICD-10 codes. We further sub-stratified this group into those with and with a secondary diagnosis of psoriasis. Chi-square tests and regression analysis were used to compare 30-day readmission rates and readmission outcomes between both groups. We excluded elective and traumatic readmissions. Results: A total of 94,461 index hospitalizations for T1DKA, that were discharged alive, were included in the analysis. 357 (0.4%) of these, had co-existing psoriasis. 15,614 (16.5%) readmissions occurred within 30 days. Readmission rates were similar between psoriasis and non-psoriasis group (15.0% vs. 16.5%, p=0.663). The psoriasis group had a similar mean hospital length of stay (3.3 days vs. 2.9 days, p=0.077) and total hospital costs ($8,435 vs. $7,231, p=0.055) compared to the non-psoriasis group. Readmissions for T1DKA in psoriasis patients was associated with a total of 1,191 hospital days and $3,014,844 in-hospital costs. T1DKA without coma was the most common reason for readmission in both groups. Conclusion: Psoriasis patients admitted for T1DM have similar 30-day readmission rates and readmission outcomes compared to non-psoriasis patients admitted for TIDM. Disclosure E. Edigin: None. P. E.

Background Community-acquired pneumonia (CAP) is associated with significant morbidity and mortality. Viral organisms have been identified as the causal pathogen in approximately 20% of CAP. Nutritional status plays an important role in the response to pneumonia. This study aims to identify whether protein energy malnutrition (PEM) is an independent risk factor for mortality and morbidity in viral CAP. Materials and methods This was a retrospective cohort study involving adult hospitalizations for viral CAP in the United States using the Nationwide Inpatient Sample (NIS) database. This cohort was further divided based on the presence or absence of a secondary discharge diagnosis of PEM. The primary outcome was inpatient mortality. Secondary outcomes included the rate of mechanical ventilation among other complications. Results The in-hospital mortality for viral CAP was 2.22%. Patients with PEM had over two-fold high adjusted odds of inpatient mortality (aOR: 2.42, 95% CI: 1.746-3.351, p < 0.001) compared with patients without PEM. Patients with PEM had higher adjusted odds of having septic shock (aOR: 3.34, 95% CI: 2.158-5.160, p < 0.001). NSTEMI (aOR: 1.75, 95% CI: 1.163-2.621, p = 0.007), need for mechanical ventilation (aOR: 3.13, 95% CI: 2.448-4.006, p < 0.001), CVA (aOR: 3.49, 95% CI: 1.687-7.220, p = 0.001), DVT (aOR: 2.19, 95% CI: 1.453-3.295, p < 0.001), and PE (aOR: 2.24, 95% CI: 1.152-4.357, p = 0.017) relative to patients without PEM. Conclusion In conclusion, coexisting PEM is associated with a higher rate of in-hospital morbidity and mortality in patients with viral CAP. Early identification and treatment of nutritional deficiencies can lead to improved outcomes and reduced costs.

Background Obesity is now a recognized chronic comorbid condition which is highly prevalent in the United States. Obesity poses several health risks, affecting multiple organ systems. The cardiovascular system is particularly affected by obesity including its role in atherosclerotic disease and hence myocardial infarction (MI) from atheromatous plaque events. However, multiple population-based studies have shown mixed outcomes in obese patients who have acute MI. This study aimed to determine if obesity paradoxically improved outcomes in patients with acute myocardial infarction (AMI) as well as compare outcomes of mild to moderately obese patients and morbidly obese patients to non-obese patients. Materials and methods Data was obtained from the Nationwide Inpatient Sample (NIS) for 2016 and 2017. The study included adult patients with a principal discharge diagnosis of AMI. This group was divided into ST segment elevation myocardial infarction (STEMI) and non-ST segment myocardial infarction (NSTEMI). Obese patients were subdivided into two groups: mild-moderate obesity and morbid obesity. Primary outcome compared inpatient mortality. Secondary outcomes included rate of percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG), composite revascularization, mean length of hospitalization, total hospital charges, and rates of complications. Results In patients with STEMI, mild to moderately obese patients had lower odds of mortality (aOR: 0.80, 95% CI: 0.715-0.906, p < 0.001) compared to non-obese patients. However, morbidly obese patients had higher odds of mortality (aOR: 1.26, 95% CI: 1.100-1.446, p < 0.001) compared to non-obese patients. Mild to moderately obese patients had higher odds of composite revascularization (aOR: 1.24, 95% CI: 1.158-1.334, p < 0.001), PCI (aOR: 1.08, 95% CI: 1.054-1.150, p = 0.014), and CABG (aOR: 1.46, 95% CI: 1.313-1.626, p < 0.001). Conclusion The degree of obesity affects outcome of patients with AMI. Cardiovascular interventions during hospitalizations for AMI also varied with degree of obesity. This may have affected the outcome, especially among morbidly obese patients.

Background Viral pneumonia is an important cause of respiratory morbidity and mortality. Cases of viral pneumonia are becoming increasingly more common as at-risk populations increase globally. We sought to highlight the racial distribution of hospitalized patients with viral pneumonia and compare their outcomes. Materials and methods Data were obtained from the Nationwide Inpatient Sample (NIS) for 2016 and 2017. The study involved adults who had a principal discharge diagnosis of viral pneumonia. The primary outcome analyzed was inpatient mortality. Secondary outcomes included the development of sepsis, septic shock, acute respiratory failure, acute respiratory distress syndrome, non-ST segment elevation myocardial infarction (NSTEMI), acute kidney failure, deep vein thrombosis, pulmonary embolism, cerebrovascular accident, need for mechanical ventilation, and use of vasopressors as well as mean length of hospitalization and mean total hospital charges. Results Blacks and Hispanics had lower inpatient mortality adjusted odds (aOR: 0.39, 95% CI = 0.229 - 0.662, p

Background: There is a scarcity of literature on co-existing psoriasis (Ps) and systemic lupus erythematosus (SLE). We used a large national population database to determine if there is any association between Ps and SLE. The primary objective was to compare the odds of being admitted for SLE in patients with Ps compared to those without Ps. The secondary objective was to compare hospital outcomes of patients admitted for SLE with co-existing Ps to those without Ps. Methods: Data were abstracted from the National Inpatient Sample (NIS) 2016 and 2017 Databases. We search for hospitalizations using ICD-10 codes. Multivariate logistic and linear regression analysis was used accordingly to adjust for confounders. Results: There were over 71 million discharges included in the database. A total of 20,630 hospitalizations had SLE as the principal diagnosis. One hundred fifty (0.7%) of these SLE hospitalizations have co-existing Ps. Hospitalizations for SLE with co-existing Ps had similar length of stay (LOS), total hospital charges, need for blood transfusion, odds of having a secondary discharge diagnosis of venous thrombosis or embolism/pulmonary embolus, and acute kidney injury compared to those without Ps. Hospitalizations with a secondary diagnosis of Ps have an adjusted odds ratio (AOR)=2.73 (95% CI 1.86-4.02, P

Introduction: Studies have shown that psoriasis increases the risk of atrial fibrillation (AF). However, it is unclear if co-existing psoriasis worsens outcomes in AF hospitalizations. This study aims to compare the outcomes of patients primarily admitted for AF with and without a secondary diagnosis of psoriasis. Methods: Data were abstracted from the National Inpatient Sample (NIS) 2016 and 2017 Database. NIS is the largest inpatient hospitalization database in the United States. The NIS was searched for hospitalizations for adult patients with AF as principal diagnosis with and without psoriasis as secondary diagnosis using ICD 10 codes. The primary outcome was inpatient mortality. Hospital length of stay (LOS), total hospital charges, odds of undergoing ablation, pharmacological, and electrical cardioversion were secondary outcomes of interest. Multivariate logistic and linear regression analysis was used accordingly to adjust for confounders. STATA software was used to analyze the data. Results: There were over 71 million hospitalizations in the combined NIS 2016 and 2017 database. Out of 821,630 hospitalizations for AF, 4,490 (0.55%) had Psoriasis. Hospitalizations for AF with psoriasis had similar inpatient mortality [0.78% vs 0.92%, AOR 0.95, 95% CI (0.44-2.04), P=0.895], total hospital charge [$41,869 vs $39,145, P=0.572] and longer LOS [3.72 vs 3.37 days, P=0.023] compared to those without psoriasis. Odds of undergoing ablation [5.0% vs 4.2%, AOR 1.12, 95% CI (0.82-1.52), P=0.481], pharmacologic cardioversion [0.11% vs 0.38%, AOR 0.29, 95% CI (0.04-2.10), P=0.219] and electrical cardioversion [19.2% vs 17.5%, AOR 0.99, 95% CI (0.83-1.19), P=0.930] were similar in both groups. Conclusion: Hospitalizations for AF with psoriasis had longer LOS compared to those without psoriasis. AF hospitalizations with psoriasis however had similar inpatient mortality, total hospital charges, odds of undergoing ablation, pharmacologic and electrical cardioversion compared to those without psoriasis.

Introduction: Systemic Lupus Erythematosus (SLE) is a chronic inflammatory autoimmune disease with effects on multiple organ systems and a wide range of clinical manifestations. Cardiovascular diseases from accelerated atherosclerosis are one of the major causes of mortality in SLE patients. This study aims to compare the outcomes of patients primarily admitted for Acute Coronary Syndrome (ACS) with and without a secondary diagnosis of SLE. Methods: Data were abstracted from the National Inpatient Sample (NIS) 2016 and 2017 Database. This database is the largest collection of inpatient hospitalization data in the United States (U.S). The NIS was searched for hospitalizations for adult patients with ACS as principal diagnosis with and without SLE as secondary diagnosis using ICD 10 codes. The primary outcome was inpatient mortality. Secondary outcomes of interest are showed in Table 1. Multivariate logistic and linear regression analysis was used accordingly to adjust for confounders. STATA software was used to analyze the data. Results: There were over 71 million discharges included in the combined 2016 and 2017 NIS database. Out of 1.3 million patients with ACS, 5,485 (0.42%) had SLE. The adjusted odds ratio (AOR) for inpatient mortality for ACS with co-existing SLE compared to those without SLE was 1.16 (95% CI 0.86-1.56, P=0.333). Hospitalizations for ACS with co-existing SLE had a decrease in adjusted mean total hospital charge of $5,164 compared to those without SLE (95% CI - {10,202-126}, P=0.045). Conclusions: Patients admitted primarily for ACS with a secondary diagnosis of SLE had less total hospital charges, but similar inpatient mortality, LOS, revascularization strategies, rates of IABP and PEAD placement compared to those without SLE. Though SLE is known to increase the risk of cardiovascular diseases, SLE does not negatively impact outcomes in patients primarily admitted for ACS based on U.S. national hospital billing data.

Introduction: Systemic Lupus Erythematosus (SLE) is known to increase the risk of atrial fibrillation (AF), however it is unclear if SLE worsens outcomes in patients admitted for AF. This study aims to compare the outcomes of patients primarily admitted for AF with and without a secondary diagnosis of SLE. Methods: Data were abstracted from the National Inpatient Sample (NIS) 2016 and 2017 Database. NIS is the largest inpatient hospitalization database in the United States. The NIS was searched for hospitalizations with AF as principal diagnosis with and without SLE as secondary diagnosis using ICD-10 codes. Hospitalizations for adult patients from the above groups were identified. The primary outcome was inpatient mortality. Hospital length of stay (LOS), total hospital charges, odds of undergoing ablation, pharmacologic, and electrical cardioversion were secondary outcomes of interest. Multivariate logistic and linear regression analysis was used accordingly to adjust for confounders. STATA software was used to analyze the data. Results: There were over 71 million discharges included in the combined 2016 and 2017 NIS database. 821,630 hospitalizations were for adult patients, who had a principal ICD-10 code for AF. 2,645 (0.3%) of these hospitalizations have co-existing SLE. SLE group were younger (67 vs 71 years, P < 0.0001) and had more females (85% vs 51%, P < 0.0001). Hospitalizations for AF with SLE had similar inpatient mortality (1.5% vs 0.91%, AOR: 1.0, 95% CI 0.47-2.14, P=0.991), LOS ( 4.2 vs 3.4 days, P=0.525), total hospital charges ( $51,351vs $39,121, P=0.056), odds of undergoing pharmacologic cardioversion ( 0.38% vs 0.38%, AOR: 0.90, 95% CI 0.22-3.69, P=0.880) and electrical cardioversion (12.9% vs 17.5%, AOR 0.87, 95% CI 0.66-1.15, P=0.324) compared to those without SLE. Hospitalizations for AF with SLE had increased odds of undergoing ablation (6.8% vs 4.2%, AOR: 1.9, 95% CI 1.3-2.7, P Conclusions: Patients admitted primarily for AF with co-existing SLE had similar inpatient mortality, LOS, total hospital charges, likelihood of undergoing pharmacologic and electrical cardioversion compared to those without SLE. However, SLE group had more odds of undergoing ablation.

Introduction: Protein Energy Malnutrition (PEM) is common among adults with chronic medical conditions, especially in patients with chronic heart, lung disease and malignancies. These conditions are associated with worse in hospital outcomes. However, the complex relationship between chronic medical conditions and PEM make the true effect of PEM on outcomes difficult to ascertain. This is compounded by the relative underdiagnosis of PEM in adults. Our study aimed to determine if PEM is an independent risk factor for adverse outcomes among patients with infective endocarditis (IE) who had mitral valve (MV) and /or aortic valve (AV) replacement surgery. Methods: Data was obtained from the National Inpatient Sample for 2016 & 2017. Studied cohort were patients with IE who underwent AV and /or MV replacement. This group was divided by presence or absence of PEM using ICD-10 codes. Primary outcome was inpatient mortality. Secondary outcomes were total hospital charges, length of stay (LOS), NSTEMI, post procedural cardiac complications, acute kidney failure (AKI) and need for intra aortic balloon pump (IABP). Multivariate logistic and linear regression models were used to compare outcomes. Results: A total of 4275 hospitalizations met the inclusion criteria, of which about a fifth (20.12%) had PEM.Patients with PEM had higher adjusted odds of post procedural cardiogenic shock (aOR: 3.65, 95% CI: 1.724 - 7.746), and need for IABP placement (aOR: 4.01, 95% CI: 1.958 - 8.199), as well as significantly higher mean difference in total hospital charges and length of stay, relative to patients without PEM. There was however no significant difference in mortality, composite post procedural cardiac complications, NSTEMI or AKI between the PEM and non-PEM subgroup. Conclusion: PEM is associated with post procedural cardiogenic shock and intra-aortic balloon pump placement in patients with infective endocarditis who underwent valve replacement surgery but this impact did not translate to higher mortality. More research is needed to elucidate the role of PEM as a major comorbidity.

Background While obesity has been clearly established as a risk factor for osteoarthritis (OA), there is a scarcity of studies comparing outcomes between obese and non-obese patients with hip OA who underwent hip arthroplasty. Methods This study involved adults with hip OA who had hip replacement procedures. Data was sourced from the Nationwide Inpatient Sample (NIS) database for 2016 and 2017. The primary outcome was inpatient mortality. Secondary outcomes included the development of non-ST segment elevation myocardial infarction (NSTEMI), sepsis, post-procedure site infection, pneumonia, acute kidney failure, deep vein thrombosis (DVT), pulmonary embolism, need for transfusion of blood products, complications involving orthopedic devices as well as mean length of hospitalization and mean total hospital charges. Results Obese patients did not have higher odds of in-hospital mortality (adjusted odds ratio [aOR]: 0.65, 95% CI 0.303-1.381, p=0.260), had increased mean length of hospitalization (0.11, 95% CI 0.083-0.134, p

Objectives This study aimed to compare the outcomes of patients primarily admitted for atrial fibrillation (AF) with and without a secondary diagnosis of rheumatoid arthritis (RA). The primary outcome of interest was inpatient mortality. Hospital length of stay (LOS), total hospital charges, and odds of undergoing ablation and pharmacologic cardioversion were the secondary outcomes of interest. Methods Data were abstracted from the National Inpatient Sample (NIS) 2016 and 2017 databases. The NIS is the largest hospitalization database in the United States (US). The NIS was searched for hospitalizations for adult patients with AF as principal diagnosis with and without RA as secondary diagnosis using the International Classification of Diseases, 10th Revision (ICD-10) codes. Multivariate logistic and linear regression analysis was used accordingly to adjust for confounders. Results There were over 71 million discharges in the combined 2016 and 2017 NIS database. Out of 821,630 AF hospitalizations, 17,020 (2.1%) had RA. Hospitalizations for AF with RA had 0.18 days' decrease in adjusted mean LOS (p=0.014), and lower total hospital charges ($38,432 vs $39,175, p=0.018) compared to those without RA. AF hospitalizations with RA had similar inpatient mortality [1.1% vs 0.91%, adjusted odds ratio (AOR): 0.90, 95% CI: 0.63-1.27, p=0.540] and odds of undergoing ablation (3.5% vs 4.2%, AOR: 1.1, 95% CI: 0.87-1.30, p=0.549) and pharmacologic cardioversion (0.38% vs 0.38%, AOR: 1.00, 95% CI: 0.53-1.89, p=0.988) compared to those without RA. Conclusions Patients admitted for AF with coexisting RA were found to have lesser adjusted mean LOS and lower total hospital charges compared to those without RA. However, inpatient mortality and the odds of undergoing ablation and pharmacologic cardioversion were similar between both groups.

Background Community-acquired pneumonia due to viral pathogens is an under-recognized cause of healthcare-associated mortality and morbidity worldwide. We aimed to compare mortality rates and outcome measures of disease severity in obese vs non-obese patients admitted with viral pneumonia. Methods Adult patients admitted with viral pneumonia were selected from the Nationwide Inpatient Sample of 2016 and 2017. The arms were stratified based on the presence of a secondary discharge diagnosis of obesity. The primary outcome was inpatient mortality. Secondary outcomes included sepsis, acute respiratory failure, acute respiratory distress syndrome, acute kidney injury, and pulmonary embolism. Results and interpretation In total, 89,650 patients admitted with viral pneumonia were analyzed, and 17% had obesity. There was no significant difference in mortality between obese and non-obese patients (aOR: 0.98, 95% CI: 0.705 - 1.362, p < 0.001). Compared to non-obese patients, obese patients had higher adjusted odds of developing acute hypoxic respiratory failure (aOR: 1.37, 95% CI: 1.255 - 1.513, p < 0.001), acute respiratory distress syndrome (aOR: 2.29, 95% CI: 1.554 - 3.381, p < 0.001), need for mechanical ventilation (aOR: 1.50, 95% CI: 1.236 - 1.819, p < 0.001), and pulmonary embolism (aOR: 1.69, 95% CI: 1.024 - 2.788, p = 0.040). Conclusions Obesity was not found to be an independent predictor of inpatient mortality in patients admitted with viral pneumonia. However, obesity is associated with worse clinical outcomes and disease severity as defined by the presence of complications, greater incidence of acute respiratory failure (ARF), acute respiratory distress syndrome (ARDS), need for mechanical ventilation, acute kidney injury (AKI), pulmonary embolism (PE), stroke, and sepsis.

Objectives: This study aims to compare the outcomes of patients admitted primarily for acute coronary syndrome (ACS) with and without a secondary diagnosis of rheumatoid arthritis (RA). Methods: Data were abstracted from the National Inpatient Sample (NIS) 2016 and 2017 Database. The NIS was searched for hospitalizations of adult patients with ACS as principal diagnoses, with and without RA as a secondary diagnosis. The primary outcome was inpatient mortality. Secondary outcomes were hospitalization characteristics and cardiovascular therapies. Multivariate logistic and linear regression analysis were used accordingly to adjust for confounders. Results: There were over 71 million discharges included in the combined 2016 and 2017 NIS database. Out of 1.3 million patients with ACS, 22,615 (1.7%) had RA. RA group was older (70.4 vs 66.8 years, P

Crowned dens syndrome (CDS) is a relatively uncommon presentation of calcium pyrophosphate dihydrate (CPPD) deposition disease that manifests as acute attacks of neck pain with fever, neck rigidity and elevated inflammatory markers related to radiodense deposits of CPPD in ligaments around the odontoid process. We present a case of CDS.

Introduction Systemic sclerosis (SSc) is known to increase the risk of ischemic stroke and other cerebrovascular events. It is, however, unclear if SSc negatively impacts the outcomes of ischemic stroke hospitalizations. This study aims to compare the outcomes of patients primarily admitted for ischemic stroke with and without a secondary diagnosis of SSc. Methods Data were extracted from the National Inpatient Sample (NIS) 2016 and 2017 database. NIS is the largest hospitalization database in the United States. We searched the database for hospitalizations of adult patients admitted with a principal diagnosis of ischemic stroke, with and without SSc as the secondary diagnosis using International Classification of Diseases, Tenth Revision (ICD-10) codes. The primary outcome was inpatient mortality, and secondary outcomes were hospital length of stay (LOS), total hospital charge, odds of undergoing mechanical thrombectomy, and receiving tissue plasminogen activator (TPA). Multivariate logistic and linear regression analysis was used to adjust for confounders. Results Over 71 million discharges were included in the NIS database for the years 2016 and 2017. Out of 525,570 hospitalizations for ischemic stroke, 410 (0.08%) had SSc. Hospitalizations for ischemic stroke with SSc had similar inpatient mortality (6.10% vs 5.53%, adjusted OR 0.66, 95% CI (0.20-2.17); p=0.492), length of stay (LOS) (5.9 vs 5.7 days; p=0.583), and total hospital charge ($74,958 vs $70,197; p=0.700) compared to those without SSc. Odds of receiving TPA (9.76% vs 9.29%, AOR 1.08, 95% CI (0.51-2.27), P=0.848) and undergoing mechanical thrombectomy (7.32% vs 5.06%, AOR 0.75, 95% CI (0.28-1.98), P=0.556) was similar between both groups. Conclusions Hospitalizations for ischemic stroke with SSc had similar inpatient mortality, LOS, total hospital charge, odds of receiving TPA, and mechanical thrombectomy compared to those without SSc.

Background Knee arthroplasty is one of the most common reasons for hospitalizations in the United States. Diabetes mellitus is thought to be associated with adverse perioperative outcomes. We sought to demonstrate the effect of comorbid diabetes on hospitalizations involving patients with knee osteoarthritis who had knee arthroplasty. Materials and methods Data was obtained from the Nationwide Inpatient Sample (NIS) for 2016 and 2017. ICD-10 codes were used to obtain a cohort of patient who were principally admitted for knee osteoarthritis who underwent knee arthroplasty. The patients were further divided according to diabetic status. The primary outcome compared inpatient mortality. Secondary outcomes included mean length of hospital stay, total hospital charges, presence of secondary diagnoses on discharge of acute kidney injury, surgical site infection, sepsis, thromboembolic events, non-ST segment elevation myocardial infarction (NSTEMI). Results Patients with diabetes mellitus had a lower adjusted odds ratio for mortality (aOR: 0.45 95% CI: 0.221 - 0.920, p = 0.029), with no significant difference in total hospital charges and length of hospital stay. Interestingly, patients with diabetes had lower odds of NSTEMI; 0.53 (95% CI: 0.369 - 0.750, p < 0.001) sepsis; 0.64 (95% CI: 0.449 - 0.924, p = 0.017) and DVT; 0.67 (95% CI: 0.546 - 0.822, p < 0.001). Conclusion Uncomplicated diabetes mellitus is not associated with adverse outcomes in patients hospitalized with knee osteoarthritis who had knee arthroplasty.

Introduction: Kidney and thyroid function and dysfunction are interrelated through several mechanisms. Thyroid hormones can also have significant impact on kidney disease so it is important to consider the physiological association of thyroid dysfunction in relation to chronic kidney disease (CKD). Research shows that hyperthyroidism is usually not associated with CKD but is known to accelerate it. We sought to determine the effect of chronic kidney disease on patient admitted with hyperthyroidism. Methods: We queried the National Inpatient Sample (NIS) databases from 2016 to 2017 for adults aged 18 and above with hyperthyroidism as a principle diagnosis with and without hypertriglyceridemia using ICD-10 codes. Multivariate logistic and linear regression analysis was used accordingly to adjust for confounders Results: There were over 71 million discharges in the combined 2016 and 2017 NIS database. Out of 17,705 hyperthyroidism hospitalizations, 4% had chronic kidney disease. Chronic kidney disease with hyperthyroidism had a similar odd of inpatient mortality (AOR 0.79, CI 0.34–4.52, P= 0.787) and cardiogenic shock (AOR 2.66, CI 0.35–20.50, P=0.347). There was a statistically significant increase in odds of acute kidney injury (AOR 2.77, CI 1.60- 4.80, P Conclusion: Chronic kidney disease is associated with similar odds of hospital mortality and cardiogenic shock among patients hospitalized for hyperthyroidism with increased odds of acute kidney injury compared to those without hyperthyroidism. It is very important to consider all clinical features and thyroid manifestations in those patients with CKD.

Introduction: Thyroid dysfunction has a great impact on lipids as well as a number of other cardiovascular risk factors. Though the effect of thyroid hormones on plasma cholesterol concentrations are well-recognized, however, there are conflicting reports about the effect of thyroid hormone on the metabolism of plasma triglycerides. We sought to determine the effect of hypertriglyceridemia on patient admitted with hyperthyroidism. Methods: We queried the National Inpatient Sample (NIS) databases from 2016 to 2017 for adults aged 18 and above with hypertriglyceridemia as a principle diagnosis with and without hyperthyroidism using ICD-10 codes. Multivariate logistic and linear regression analysis was used accordingly to adjust for confounders. Results: There were over 71 million discharges in the combined 2016 and 2017 NIS database. Out of 17,705 hyperthyroidism hospitalizations, 15% had hypertriglyceridemia. Hypertriglyceridemia with hyperthyroidism had a similar odds of inpatient mortality (AOR 0.37, CI 0.06–1.99, P=0.246), acute kidney injury (AOR 1.03, CI 0.706–1.510, P=0.868) and cardiogenic shock (AOR 0.96, CI 0.134–6.72, P=0.963). There was a statistically significant increase in odds of acute respiratory failure (AOR 0.46, CI- 0.21- 0.99, P=0.048) in those hospitalized with hyperthyroidism and hypertriglyceridemia compared to those with hyperthyroidism alone. Conclusion: Hypertriglyceridemia is associated with similar outcomes in patient admitted for hyperthyroidism in terms of mortality, acute kidney injury and acute cardiogenic shock with an increased odd of acute respiratory failure. More research is needed to explain the pathophysiologic mechanism underlying the effect of hypertriglyceridemia on hyperthyroidism.

Introduction: Hidradenitis suppurativa (HS) or acne inversa is a chronic, inflammatory, recurrent, debilitating skin disease. There have been studies linking HS to metabolic syndrome [1]. However, there is a scarcity of studies on metabolic and endocrine co-morbidities of hospitalized HS patients. This study aims to compare the prevalence of metabolic and endocrine co-morbidities in hospitalized HS patients to hospitalized non-HS patients. Methods: Data were abstracted from the National Inpatient Sample (NIS) 2016 and 2017 Database. NIS is the largest inpatient hospitalization database in the United States. The NIS was searched for hospitalizations for adult patients aged 18 years or above with a principal or secondary diagnosis of HS and those without any diagnosis of HS. Chi-square test was used to compare the prevalence of common metabolic and endocrine comorbidities between HS and non-HS hospitalized patients. Co-morbidities were obtained from secondary diagnoses. We used ICD-10 codes to obtain HS hospitalizations and co-morbidities. STATA, version 16 was used for analysis. Results: There were over 71 million discharges in the combined 2016 and 2017 NIS database. Out of which, 40,275 hospitalizations had a diagnosis of HS. HS hospitalizations had higher prevalence of type 2 diabetes (33.1% vs 24.5%, p Conclusion: Hospitalized HS patients have a higher prevalence of type 1 & 2 diabetes mellitus and obesity compared to hospitalized non-HS patients. An interdisciplinary approach involving the endocrinologist, dermatologist, and hospitalist may be needed to optimally manage these co-morbidities in hospitalized HS patients. References 1. Ergun T.
