Angiotensin Receptor Neprilysin Inhibitor Use and Blood Pressure Lowering in Patients With Heart Failure With Reduced Ejection Fraction Across the Spectrum of Kidney Function: An Analysis of the Veterans Administrative Health System.

BACKGROUND: A substantial proportion of patients with heart failure and kidney disease have poorly controlled blood pressures. This study aimed to evaluate patterns of blood pressure after initiation of an angiotensin receptor neprilysin inhibitor (ARNI) or an angiotensin-converting enzyme inhibitor (ACEI)/angiotensin receptor blocker (ARB) across the spectrum of kidney function. METHODS: Between 2016 and 2020, we evaluated 26,091 patients admitted to a Veterans Affairs hospital for an acute heart failure exacerbation with reduced ejection fraction. We assessed patterns of systolic and diastolic blood pressure among those started on ARNI or ACEI/ARB over 6 months, overall and across estimated glomerular filtration rate (eGFR). To account for differential treatment factors, we applied 1:1 propensity score matching using 15 known baseline covariates. RESULTS: There were 13,781 individuals treated with an ACEI or ARB and 2589 individuals treated with an ARNI prescription. After propensity score matching, 839 patients were matched in each of the ARNI and ACEI/ARB groups. Mean baseline estimated glomerular filtration rate (eGFR) was 63.8 (standard deviation 21.6), and 10% had stage 4 or 5 chronic kidney disease. Patients in the ARNI group experienced greater systolic blood pressure reduction at month 3 (-5.2 mmHg vs -2.2 mmHg, ARNI vs ACEI/ARB; P < 0.001), and month 6 (-4.7 mmHg vs -1.85 mmHg, ARNI vs ACEI/ARB; P < 0.001). These differences in systolic blood pressure by 6 months did not vary by eGFR above and below 60 mL/min/1.73m2 or continuously across a wide range of eGFR (Pinteraction > 0.10 for both). CONCLUSION: The use of ARNI was associated with significant reduction in blood pressure as compared to the ACEI/ARB group overall and across the eGFR spectrum, including in advanced chronic kidney disease.

Proportional troponin changes and risk for outcomes with intervention strategies in non-ST-elevation acute coronary syndrome across kidney function.

AIMS: This analysis evaluates whether proportional serial cardiac troponin (cTn) change predicts benefit from an early versus delayed invasive, or conservative treatment strategies across kidney function in non-ST-elevation acute coronary syndrome (NSTE-ACS). METHODS: Patients diagnosed with NSTE-ACS in the Veterans Health Administration between 1999 and 2022 were categorized into terciles (<20%, 20 to ≤80%, >80%) of proportional change in serial cTn. Primary outcome included mortality or rehospitalization for myocardial infarction at 6 and 12 months, in survivors of index admission. Adjusted hazard ratio (HR) with 95% confidence Intervals (95% confidence interval [CI]) were calculated for the primary outcome for an early invasive (≤24 h of the index admission), delayed invasive (>24 h of index admission to 90-days postdischarge), or a conservative management. RESULTS: Chronic kidney disease (CKD) was more prevalent (45.3%) in the lowest versus 42.2% and 43% in middle and highest terciles, respectively (p < 0.001). Primary outcome is more likely for conservative versus early invasive strategy at 6 (HR: 1.44, 95% CI: 1.37-1.50) and 12 months (HR: 1.44, 95% CI: 1.39-1.50). A >80% proportional change demonstrated HR (95% CI): 0.90 (0.83-0.97) and 0.93 (0.88-1.00; p = 0.041) for primary outcome at 6 and 12 months, respectively, when an early versus delayed invasive strategy was used, across CKD stages. CONCLUSIONS: Overall, the invasive strategy was safe and associated with improved outcomes across kidney function in NSTE-ACS. Additionally, >80% proportional change in serial troponin in NSTE-ACS is associated with benefit from an early versus a delayed invasive strategy regardless of kidney function. These findings deserve confirmation in randomized controlled trials.

Non-steroidal mineralocorticoid receptor antagonists and cardiorenal outcomes in chronic kidney disease.

The burden of adverse cardiorenal outcomes among patients with the trifecta of diabetes, heart failure (HF) and chronic kidney disease (CKD) remains high. Steroidal mineralocorticoid receptor antagonists (MRAs) have been shown to improve clinical outcomes in patients with HF, however, there is significant underutilization of these agents, especially in patients with advanced CKD. Non-steroidal MRAs are an emerging therapeutic option for patients with diabetic kidney disease and are now guideline-supported in this population. Non-steroidal MRAs have a unique pharmacological profile distinct from their steroidal counterparts that retains the class-specific cardiorenal benefits but may help mitigate adverse effects, especially hyperkalaemia, in patients with CKD. In this review we summarize the current evidence on the use of non-steroidal MRAs for improving cardiorenal outcomes in patients with CKD and diabetes, as well as for combination use alongside other foundational medical therapies used in HF and CKD.

Adjunctive Dexmedetomidine in Alcohol Withdrawal Syndrome: A Systematic Review and Meta-analysis of Retrospective Cohort Studies and Randomized Controlled Trials.

OBJECTIVE: To investigate whether dexmedetomidine (DEX), as adjunctive therapy to benzodiazepine (BZD), is superior to BZD alone in critically ill patients with alcohol withdrawal syndrome (AWS). DATA SOURCES: PubMed Central, Cochrane CENTRAL, ClinicalTrials.gov and Google Scholar were used as search databases. Specific keywords and MeSH terms were "dexmedetomidine," "benzodiazepine," and "alcohol withdrawal syndrome." The last search was on September 16, 2022. STUDY SELECTION AND DATA EXTRACTION: Randomized controlled trials (RCTs) and nonrandomized/cohort studies exploring the use of DEX in the management of AWS were included. A total of 12 studies were included in the systematic review and 7 in the meta-analysis. DATA SYNTHESIS: The intensive care unit length of stay (ICU LOS) was found to have a mean difference (MD) of 48.06 [37.48, 58.64], P = <0.001 for the cohort subgroup, significantly favoring the DEX arm, but, in contrast, pooled RCT data showed a result of -20.07 [-36.86, -3.28], P = 0.02, a shorter ICU LOS for the DEX arm. Bradycardia and hypotension incidence significantly favored the BZD arm in both subgroups. This study compares the effectiveness of adjunctive DEX in clinical practice and aims to help providers in critical decision-making by compiling and analyzing the best current available evidence of its use in AWS. CONCLUSIONS: Based on low to very low level of evidence, adjunctive DEX showed no significant difference for ICU LOS when compared with BZD alone. Pooled randomized trials potentially show a benefit but are similarly limited by their low quality of evidence.

Clinical characteristics and treatment of patients with central pulmonary embolism and right heart thrombus.

INTRODUCTION: Right heart thrombus (RHT), also known as clot in transit, is an uncommon finding in pulmonary embolism (PE) that is associated with increased inpatient mortality. To date, there is no consensus on the management of RHT. Therefore, we aim to describe the clinical features, treatments, and outcomes of patients with simultaneous RHT and PE. METHODS: This is a retrospective, cross-sectional, and single-center study of hospitalized patients with central PE who had RHT visualized on transthoracic echocardiography (TTE) from January 2012 to May 2022. We use descriptive statistics to describe their clinical features, treatments, and outcomes, including mechanical ventilation, major bleeding, inpatient mortality, length of hospital stay, and recurrent PE on follow-up. RESULTS: Of 433 patients with central PE who underwent TTE, nine patients (2%) had RHT. The median age was 63 years (range 29-87), most were African American (6/9), and females (5/9). All patients had evidence of RV dysfunction and received therapeutic anticoagulation. Eight patients received RHT-directed interventions, including systemic thrombolysis (2/9), catheter-directed suction embolectomy (4/9), and surgical embolectomy (2/9). Regarding outcomes, 4/9 patients were hemodynamically unstable, 8/9 were hypoxemic, and 2/9 were mechanically ventilated. The median length of hospital stay was six days (range 1-16). One patient died during hospital admission, and two patients had recurrent PE. CONCLUSION: We described the different therapeutic approaches and outcomes of patients with RHT treated in our institution. Our study adds valuable information to the literature, as there is no consensus on the treatment of RHT. HIGHLIGHTS: Right heart thrombus (RHT) was a rare finding in central pulmonary embolism. Most patients with RHT had evidence of RV dysfunction and pulmonary hypertension. Most patients received RHT-directed therapies in addition to therapeutic anticoagulation.

Follow Up Imaging in Hepatocellular Cancer Ultrasound Screening Exams With Poor Visualization Scores.

OBJECTIVES: The Ultrasound Liver Imaging Reporting and Data Systems (LI-RADS) provides standardized terminology and reporting for ultrasound (US) examinations performed for hepatocellular cancer (HCC) screening. However, there are no recommendations regarding follow up imaging for visualization scores with suboptimal visualization. Therefore, the aim of this study is to examine follow up imaging practices in the setting of US studies scored as B (moderate limitations) and C (severe limitations). METHODS: A single center retrospective analysis of studies from 2017 to 2021 with HCC US screening visualization scores of B and C was performed. Follow up imaging with US, CT, or MRI within 6 months with visualization score B or C on initial US were included. RESULTS: Five hundred and sixty HCC US studies with suboptimal imaging were reviewed. Of those with follow up imaging, patients with a visualization score of B underwent US in more than half (58%) of the cases while those with visualization score of C underwent more CT/MRI studies (62.5%, P = .12) Patients with visualization score of B had more MRI exams performed (55%) while patients with a visualization score of C underwent more CT exams (70%, P = .16). CONCLUSIONS: Currently, there are no guidelines instructing follow up imaging on HCC screening ultrasounds with poor visualization, and the data suggests that providers have taken a heterogeneous approach. This suggests a need for society recommendations on how to approach HCC screening ultrasounds in patients with suboptimal studies.

Cardiorenal Protection With the Newer Antidiabetic Agents in Patients With Diabetes and Chronic Kidney Disease: A Scientific Statement From the American Heart Association.

Chronic kidney disease (CKD) with type 2 diabetes (T2D) is a major public health problem, resulting in significant cardiovascular and kidney adverse outcomes worldwide. Despite the widespread use of standard-of-care therapies for CKD with T2D over the past few decades, rates of progression to end-stage kidney disease remain high with no beneficial impact on its accompanying burden of cardiovascular disease. The advent of the newer classes of antihyperglycemic agents, including SGLT2 (sodium glucose cotransporter 2) inhibitors and GLP-1 (glucagon-like peptide-1) receptor agonists, has changed the landscape of therapeutic options for patients with CKD with T2D, with demonstration of significant reductions in cardiovascular adverse events and progression to end-stage kidney disease. Several potential mechanisms exist through which these beneficial effects are achieved in both drug classes, which may be independent of their antihyperglycemic effects. This scientific statement summarizes the current literature on the cardiorenal protective effects with SGLT2 inhibitors and GLP-1 receptor agonists in patients with CKD and T2D. It reviews potential mechanistic pathways that may drive these benefits and summarizes the literature on adverse effects in patients with CKD and T2D at risk for or with established cardiovascular disease. Last, it provides practical guidance on a proposed collaborative care model bridging cardiologists, nephrologists, endocrinologists, and primary care physicians to facilitate the prompt and appropriate integration of these therapeutic classes in the management of patients with T2D and CKD.

Factors associated with hospital readmissions among patients with COVID-19: A single-center experience.

Identify factors associated with readmission after an index hospital admission for coronavirus disease 2019 (COVID-19) infection in a single center serving an underserved and predominantly minority population. This retrospective descriptive study included 275 patients who tested COVID-19 positive via reverse transcriptase-polymerase chain reaction assay at our institution and who survived the index hospitalization. The main outcomes were 1- and 6-month readmission rates after an index hospitalization for COVID-19. The mortality rate among the readmitted patients was also determined. Factors independently associated with readmission were investigated using multivariable logistic regression. A final sample of 275 patients was included. The mean age was 64.69 ± 14.64 (SD), 133 (48%) were female and 194 (70%) were African American. Their chronic medical conditions included hypertension 203 (74%) and diabetes mellitus 121 (44%). After the hospitalization, 1-month readmission rate was 7.6%, while 6-month readmission rate was 24%. Nine percent of patients who were readmitted subsequently died. Coronary artery disease (CAD) was significantly associated with 6-month readmission odds ratio (OR), 2.15 (95% confidence interval [CI]: 1.04-4.44; p = 0.039) after adjustment for age, gender, ethnicity, and comorbidities. Readmissions were due to cardiac, respiratory, and musculoskeletal symptoms. Hispanic ethnicity was associated with increased readmission OR, 3.16 (95% CI: 1.01-9.88; p = 0.048). No significant difference was found between inflammatory markers or clinical outcomes during the index hospitalization among patients who were readmitted compared to those who were not. A significant number of patients hospitalized for COVID-19 may be readmitted. The presence of CAD is independently associated with high rates of 6-month readmission.

Bacterial infections and patterns of antibiotic use in patients with COVID-19.

Bacterial coinfection is associated with poor outcomes in patients with viral pneumonia, but data on its role in the mortality of patients with coronavirus disease 2019 (COVID-19) is limited. This is a single-center retrospective analysis of 242 patients with confirmed COVID-19 admitted to both intensive care and non-intensive care settings. Bacterial coinfection was determined by the presence of characteristic clinical features and positive culture results. Multivariable logistic regression was used to analyze the association of concomitant bacterial infection with inpatient death after adjusting for demographic factors and comorbidities. Antibiotic use pattern was also determined. Bacterial coinfection was detected in 46 (19%) patients. Genitourinary source was the most frequent, representing 57% of all coinfections. The overall mortality rate was 21%. Concomitant bacterial infections were independently associated with increased inpatient mortality (OR, 5.838; 95% CI, 2.647-12.876). Patients with bacterial coinfection were relatively older (71.35 ± 11.20 vs 64.78 ± 15.23; P = .006). A total of 67% of patients received antibiotic therapy, yet 72% did not have an obvious source of bacterial infection. There was a significantly higher rate of inpatient mortality in patients who received antibiotics compared to those who did not (30% vs 5%; P < .0001). Bacterial coinfection in COVID-19 is associated with increased mortality.

Characteristics and clinical outcomes of COVID-19 patients in an underserved-inner city population: A single tertiary center cohort.

There is limited information describing the characteristics and clinical outcomes of patients infected with coronavirus disease 2019 (COVID-19) especially those in underserved urban area with minority population in the United States. This is a retrospective single-center study for patients who were admitted with COVID-19 infection. Data collection was from 1 March through 24 April 2020. Demographic, clinical, laboratory, and treatment data were presented using descriptive statistics and frequencies. The χ2 test and multivariate logistic regression were used to determine association of risk factors and clinical outcomes. A total of 242 inpatients were included with a mean age of 66 ± 14.75 (±standard deviation). A total of 50% were female and 70% were African American. Comorbidities included hypertension (74%), diabetes mellitus (49%), and 19% had either COPD or asthma. Older age was associated with higher risk of inpatient death odds ratio (OR): 1.056 (95% confidence interval [CI]: 1.023-1.090; P = .001). Inpatient mortality occurred in 70% who needed mechanical ventilation (OR: 29.51; 95% CI: 13.28-65.60; P < .0001), 58% who required continuous renal replacement therapy/hemodialysis (CRRT/HD) (OR: 6.63; 95% CI: 2.74-16.05; P < .0001), and 69% who needed vasopressors (OR: 30.64; 95% CI: 13.56-69.20; P < .0001). Amongst biomarkers of disease severity, only baseline CRP levels (145 ± 116 mg/L) were associated with mortality OR: 1.008 (95% CI: 1.003-1.012; P = .002). Majority of hospitalized patients had hypertension and diabetes. Older age was an independent risk factor for inpatient mortality. Requirement of mechanical ventilation, vasopressor use, and CRRT/HD was associated significantly with inpatient mortality. Higher baseline CRP was significantly associated with inpatient death.

Etiologies and predictors of readmission among obese and morbidly obese patients admitted with heart failure.

The relationship between severity of obesity and outcomes in heart failure (HF) has long been under debate. We studied index HF admissions from the 2013-14 National Readmission Database. Admissions were separated into three weight-based categories: non-obese (Non-Ob), obese (Ob), and morbidly obese (Morbid-Ob) to analyze hospital mortality and readmission at 30 days and 6 months. We investigated etiologies and predictors of 30-day readmission among these weight categories. We studied a total of 578,213 patients of whom 3.0% died during index hospitalization (Non-Ob 3.3% vs. Ob 1.9% vs. Morbid-Ob 1.9%; p < 0.01). Non-Ob comprised 79.5%, Ob 9.9%, and Morbid-Ob 10.6% of patients. Morbid-Ob patients were the youngest among age categories and more likely to be female. In-hospital mortality during readmission at 30 days and 6 months was significantly lower among Morbid-Ob and Ob compared with Non-Ob patients (all p < 0.01). Thirty-day readmission among Morbid-Ob was lower than Non-Ob and higher than Ob patients (19.6% vs. 20.5% vs. 18.6%, respectively; p < 0.01). Morbid-Ob patients were less likely to be readmitted for cardiovascular etiologies compared with both Ob and Non-Ob (45.0% vs. 50.3% vs. 50.6%; p < 0.01). Multivariable regression analysis revealed that Ob (adjusted odds ratio 0.84, 95% confidence intervals 0.82-0.86) and Morbid-Ob (aOR 0.83, 95% CI 0.81-0.85) were independently associated with lower 30-day readmission. Readmission at 6 months was highest among Morbid-Ob followed by Non-Ob and Ob (51.1% vs. 50.2% vs. 49.1%, p < 0.01). Morbid-Ob and Ob patients experience lower in-hospital mortality during index HF admission and during readmission with 30 days or 6 months compared with Non-Ob. Morbid-Ob patients experience greater readmission at 6 months despite the lower rate at 30 days post discharge. Morbid-Ob patients are most likely to be readmitted for non-cardiovascular causes.

Clinical outcomes in patients with heart failure with and without cirrhosis: an analysis from the national inpatient sample.

Outcomes of heart failure (HF) hospitalization are driven by the presence or absence of comorbid conditions. Cirrhosis is associated with worse outcomes in patients with HF, and both HF and cirrhosis are associated with worse renal outcomes. Using a nationally representative sample we describe inpatient outcomes of all-cause mortality and length of stay (LOS) among patients with and without cirrhosis hospitalized for decompensated with HF. We conducted a cross sectional analysis using Nationwide Inpatient Sample (2010-2014) data including patients hospitalized for decompensated HF, with or without cirrhosis. We calculated the adjusted odds of all-cause mortality, acute kidney injury (AKI), and target LOS after adjusting for potential confounders. Out of the 2,487,445 hospitalized for decompensated HF 39,950 had cirrhosis of which majority (75.1%) were non-alcoholic cirrhosis. Patients with comorbid cirrhosis were more likely to die (OR, 1.26; 95% CI, 1.11 to 1.43) and develop AKI (OR, 1.26; 95% CI, 1.16 to 1.36) as compared to those without cirrhosis. Underlying CKD was associated with a greater odds of AKI (OR, 4.99; 95% CI, 4.90 to 5.08), and the presence of cirrhosis amplified this risk (OR, 6.03; 95% CI, 5.59 to 6.51). There was approximately a 40% decrease in the relative odds of lower HF hospitalization length of stay among those with both CKD and cirrhosis, relative to those without either comorbidities. Cirrhosis in patients with hospitalizations for decompensated HF is associated with higher odds of mortality, decreased likelihood of discharge by the targeted LOS, and AKI. Among patients with HF the presence of cirrhosis increases the risk of AKI, which in turn is associated with poor clinical outcomes.

Angiotensin converting enzyme inhibitors and angiotensin receptor blockers in acute heart failure: invasive hemodynamic parameters and clinical outcomes.

There are limited data regarding the use of angiotensin converting enzyme inhibitors/angiotensin receptor blockers (ACEi/ARBs) in acute heart failure (AHF). The purpose is to determine the patterns of ACEi/ARB use at the time of admission and discharge in relation to invasive hemodynamic data, mortality, and heart failure (HF) readmissions. This is a retrospective single-center study in patients with AHF who underwent right heart catheterization between January 2010 and December 2016. Patients on dialysis, evidence of shock, or incomplete follow up were excluded. Multivariate logistic regression analysis was used to analyze the factors associated with continuation of ACEi/ARB use on discharge and its relation to mortality and HF readmissions. The final sample was 626 patients. Patients on ACEi/ARB on admission were most likely continued on discharge. The most common reasons for stopping ACEi/ARB were worsening renal function (WRF), hypotension, and hyperkalemia. Patients with ACEi/ARB use on admission had a significantly higher systemic vascular resistance (SVR) and mean arterial pressure (MAP), but lower cardiac index (CI). Patients with RA pressures above the median received less ACEi/ARB (P = 0.025) and had significantly higher inpatient mortality (P = 0.048). After multivariate logistic regression, ACEi/ARB use at admission was associated with less inpatient mortality; OR 0.32 95% CI (0.11 to 0.93), and this effect extended to the subgroup of patients with HFpEF. Patients discharged on ACEi/ARB had significantly less 6-month HF readmissions OR 0.69 95% CI (0.48 to 0.98). ACEi/ARB use on admission for AHF was associated with less inpatient mortality including in those with HFpEF.

Risk factors associated with intubation and readmissions in patients with angioedema: A single-center experience al. / Ann Allergy Asthma Immunol 127 (2021) xxx-xxx"?>.

BACKGROUND: Given the heterogeneity of etiologies, pathophysiology, and presentation of angioedema, variations in clinical outcomes, such as intubation and hospital readmissions, need further clarification. OBJECTIVE: To determine the factors associated with intubation and hospital readmissions in patients with angioedema. METHODS: Retrospective study of patients evaluated with a diagnosis of angioedema in a 6-year period. Demographic and clinical data, such as medication use, family history, comorbidities, and symptoms, were recorded. Multivariable logistic regression was used to analyze factors associated with intubation, whereas Cox regression was used to analyze readmissions. RESULTS: Of 636 patients, the most common cause of angioedema was that induced by angiotensin-converting enzyme inhibitor (ACEI) at 58%. The overall mortality was 0.5%. After adjusting for sex, race, comorbidities, and type of angioedema, smoking (odds ratio [OR], 1.79; 95% confidence interval [CI], 1.10-2.93; P = .02), calcium channel blocker therapy (OR, 1.91; 95% CI, 1.18-3.10; P = .009), histaminergic symptoms (OR, 3.21; 95% CI, 1.93-5.33; P < .001), and age (OR, 1.02; 95% CI, 1.00-1.04; P = .02) were independently associated with increased odds of intubation. Involvement of either the pharynx, larynx, or tongue was associated with higher odds of intubation (OR, 20.96; 95% CI, 10.63-41.33; P < .001). A total of 10% of the patients had a readmission for angioedema within 90 days, and 75% occurred within 30 days. After multivariable Cox regression analysis, only chronic obstructive pulmonary disease and asthma (OR, 2.13; 95% CI, 1.12-4.07; P = .02) and ACEI-related angioedema (OR, 2.93; 95% CI, 1.33-6.47; P = .008) were significantly associated with readmissions. CONCLUSION: Smoking, calcium channel blocker use, histaminergic symptoms, age, and upper airway involvement were markedly associated with intubation. The presence of chronic obstructive pulmonary disease, asthma and ACEI-related angioedema were independently associated with increased odds of readmission.

Insulin Use and Poor COVID-19 Outcomes among Diabetes Patients: Association Not Necessarily Causation.

Our study looked at the relationship between insulin use and clinical outcomes in COVID-19. A response to our article, written by Dr. Chia Sing Kow and Dr. Syed Shahzad Hasan raised a few questions. They mentioned our use of hemoglobin A1c may be inaccurate as the patients in our study had high rates of CKD or ESRD which could alter the hemoglobin A1c levels. However due to the limitations of our patient population and perhaps in a lot of other sample populations in the real-world setting, it was the most feasible way to represent glucose control.The writers also suggested that the use of metformin, a potential confounder, was also not adjusted for. This should be considered in future research but addition of too many variables in a regression model may lead to less reliability of results for our study.The letter writers also suggested that the results of our paper may lead to misinterpretation by readers and may influence providers to not use insulin therapy for their patients when necessary due to fear of worse outcomes in the setting of COVID-19. We reiterated that it is very important that the data not be misinterpreted, and that nowhere in our paper did we imply or suggest that patients who need insulin therapy to treat their diabetes should not receive proper therapy due to the association we delineated in our paper. Instead, more careful surveillance of patients with advanced diabetes is needed especially when admitted with COVID-19.

Insulin Use, Diabetes Control, and Outcomes in Patients with COVID-19.

Background: The novel coronavirus (SARS CoV-2) has caused significant morbidity and mortality in patients with diabetes. However, the effects of diabetes control including insulin use remain uncertain in terms of clinical outcomes of patients with COVID-19.Methods: In this single-center, retrospective observational study, all adult patients admitted to Einstein Medical Center, Philadelphia, from March 1 through April 24, 2020 with a diagnosis of COVID-19 and diabetes were included. Demographic, clinical and laboratory data, insulin dose at home and at the hospital, other anti-hyperglycemic agents use, and outcomes were obtained. Multivariate logistic regression was used to evaluate the factors associated with diabetes control and mortality.Results: Patients who used insulin at home had higher mortality compared to those who did not (35% vs 18% p = .015), this was true even after adjustment for demographics, comorbidities and a1c OR 2.65 95% CI (1.23-5.71) p = .013. However, the mean a1c and the median home requirements of insulin did not significantly differ among patients who died compared to the ones that survived. Patients who died had significantly higher inpatient insulin requirements (highest day insulin requirement recorded in units during hospitalization) 36 (11-86) vs 21 (8-52) p = .043 despite similar baseline a1c and steroid doses received. After adjusting for demographics, comorbidities and a1c, peak insulin requirements remained significantly associated with inpatient mortality OR 1.022 95% CI (1.00-1.04) p = .044.Conclusion: Among diabetic patients infected with COVID-19, insulin therapy at home was significantly independently associated with increased mortality. Peak daily inpatient insulin requirements was also independently associated with increased inpatient mortality.

Characteristics of peripheral blood differential counts in hospitalized patients with COVID-19.

BACKGROUND: A lot remains unknown about the features and laboratory findings that may predict worse outcomes in patients with coronavirus disease 2019 (COVID-19). The aim of this study was to evaluate the difference in complete blood count parameters and differential counts in patients hospitalized with COVID-19 who survived compared to those who died. DESIGN: We performed a single-center retrospective study including 242 patients with confirmed COVID-19. We described the characteristics of the complete blood count parameters in these patients. Mann-Whitney U test was used to compare hematologic parameters of patients who died and those who survived; multivariate logistic regression was used to look for associations with mortality. RESULTS: Patients with COVID-19 who died had significantly lower median absolute monocyte count (AMC) (0.4 vs 0.5, P = .039) and median platelet count (169 vs 213, P = .009) compared to those who survived. Patients who died had a significantly higher neutrophil-to-lymphocyte ratio (6.4 vs 4.5, P = .001). The NLR was positively associated with death (OR = 1.038; 95% CI, 1.003-1.074, P = .031), while AMC was inversely associated with death (OR = 0.200; 95% CI, 0.052-0.761, P = .018). CONCLUSION: Among patients with COVID-19, a lower AMC and higher NLR are associated with higher mortality.

Acute coronary syndromes in the peri-operative period after kidney transplantation in United States.

INTRODUCTION: Chronic kidney disease is an independent risk factor for cardiovascular disease. Despite careful preoperative evaluation, there is a risk of acute coronary syndromes after kidney transplant. METHODS: The National Inpatient Sample for the years 2004-2013 was used for this retrospective cohort study. All adult patients undergoing kidney transplantation were identified using the appropriate ICD-9-CM codes. Multivariate logistic regression was used to identify predictors of acute coronary syndromes in the peri-operative period after kidney transplantation. RESULTS: A total of 147 431 kidney transplants were performed from 2004 through 2013 in the United States. The average peri-operative in-hospital mortality was 0.5%. Acute coronary syndrome occurred in 1.3% patients in the peri-operative period. Half of patients with acute coronary syndromes had pre-existing coronary artery disease. The strongest predictors of acute coronary syndromes included older age: 45-64 years. OR 3.28 95% CI (1.85-5.83), ≥65 years. OR 4.84 (2.59-9.05), race: African American, OR 0.66 (0.47-0.93) and pre-existing coronary artery disease OR 3.83 (2.84-5.15). The case fatality rates were 16.9% and 5.3% for STEMI and NSTEMI, respectively. The overall mortality for any ACS event was 7.1%. CONCLUSION: Acute coronary syndrome in the immediate peri-operative period after kidney transplantation is rare but is associated with high rates of mortality.

Aortic stenosis calcium scoring in a racially mixed sample.

Aortic stenosis (AS) is common and increasing in prevalence as the population ages. Using computed tomography (CT) to quantify aortic valve calcification (AVC) it has been reported that men have greater degrees of calcification than women among subjects with severe AS. These data, however, were derived in largely Caucasian populations and have not been verified in non-Caucasian subjects. This retrospective study identified 137 patients with severe AS who underwent valve replacement and had CT scans within 6 months prior to surgery. AVC scores were compared between men and women, both in the entire sample and in racial subgroups. 52% of subjects were male and 62.8% were non-Caucasian. Mean AVC score for the entire cohort was 3062.08±2097.87 with a range of 428-13,089. Gender differences in aortic valve calcification were found to be statistically significant with an average AVC score of 3646±2422 in men and 2433±1453 in women (p=0.001). On multivariate analysis, gender remained significantly associated with AVC score both in the entire sample (p=0.014) and in the non-Caucasian subgroup (p=0.008). Mean AVA was significantly greater in males than females but this difference disappeared when AVA was indexed to BSA (p=0.719). AVA was not different between racial groups (p=0.369). In this research we observed that among subjects with severe AS men have higher AVC scores than women regardless of racial background. This is consistent with previous studies in predominantly Caucasian populations.

Trends in the prevalence of malignancy among patients admitted with acute heart failure and associated outcomes: a nationwide population-based study.

Cancer is the second leading cause of death in the USA, and cardiovascular disease is the second leading cause of morbidity and mortality among cancer survivors. Cancer survivors share common risk factors for cardiovascular disease with non-cancer patients. With improved survival, cancer patients become susceptible to treatment-related toxicity often involving the heart. The impact of concurrent malignancy on outcomes particularly among heart failure patients is an area of active research. We studied the trends in the prevalence of a concurrent diagnosis of breast, prostate, colorectal, and lung cancer among admissions for acute heart failure and the associated trends for in-hospital mortality. Patients aged ≥ 18 years who were admitted with a primary diagnosis of "congestive heart failure" (CCS codes 99 and 108) from years 2003 to 2014 were included. We analyzed the rate of admission and in-hospital mortality among patients who had a concurrent diagnosis for either lung cancer, colorectal cancer, breast cancer (among females), or prostate cancer (among males). We performed a multivariate analysis to assess the role of a concurrent diagnosis of any cancer in predicting in-hospital mortality among HF admissions. From 2003 to 2014 across over 12 million HF admissions, ≈ 7% had a concurrent diagnosis of either lung, breast, colorectal, or prostate cancer. The prevalence was highest for breast cancer (2.3%) followed by prostate cancer (2.1%) and colorectal cancer (1.5%) and lowest with lung cancer (1.1%). The prevalence of cancer increased over the duration of study among all four cancer types with the largest increase in prevalence of breast cancer. Baseline comorbidities including hypertension, diabetes, smoking, chronic kidney disease, and coronary artery disease increased over time among patients with and without cancer. In-hospital mortality was higher among those with a diagnosis of lung cancer (5.9%) followed by colorectal cancer (4.0%), prostate cancer (3.5%), no diagnosis of cancer (3.3%), and breast cancer (3.2%). In-hospital mortality declined across HF admissions with and without a cancer diagnosis from 2003 to 2014. Decline in such mortality among heart failure was highest for patients with lung cancer (8.1 to 4.6% from 2003 to 2014; p < 0.001). Multivariate analysis showed that a concurrent diagnosis of cancer was associated with a marginally lower hospital mortality compared with controls (adjusted odds ratio 0.95, 95% confidence interval 0.94-0.96; p < 0.001). Among HF admissions, the prevalence of a concurrent cancer diagnosis increased over time for breast, lung, colorectal, and prostate cancer. Baseline in-hospital mortality was higher among HF admissions with either lung cancer, colorectal cancer, or prostate cancer and lower with breast cancer compared with controls without a cancer diagnosis. Adjusted analysis revealed no evidence for higher hospital mortality among HF admissions with any accompanying cancer diagnosis.
