ABSTRACT
Adenoid cystic carcinoma (ACC) is a rare epithelial tumor that is found in the salivary glands. It is typically slow-growing and follows an indolent course. While it can hematogenously spread to the lungs, distant metastases are rarely reported. Primary ACC in the lung is not common and makes up only 0.04-0.2% of all primary lung tumors. In addition, metastasis of the ACC to liver and bilateral kidneys is not common frequently documented. In this case report, we present a patient with unusual metastases of ACC, as well as non-specific symptoms that warrant discussion for ACC as potential differentials in the appropriate clinical setting.
ABSTRACT
OBJECTIVES: Since the inception of the coronavirus disease 2019 (COVID-19) pandemic, the United States has been the leader in cases and deaths. Healthcare workers treating these severely ill patients are at risk of many deleterious consequences. Residents, in particular, may be affected by physical as well as psychological consequences. Because data are sparse on perceptions, coping strategies, and the mental health of residents during COVID-19, we explored these issues in survey data from a community-based academic program in the southeastern United States. METHODS: In May 2020, when US deaths from COVID-19 reached 100,000, we administered multiple-choice online anonymous surveys to assess resident perceptions, coping strategies, and self-reported levels of depression, anxiety, and stress. We used the COPE inventory to assess coping strategies and the Depression, Anxiety, and Stress Scale-21 questionnaire. RESULTS: A total of 59 (41.3%) of 143 eligible residents completed the survey, 52 (88.1%) of whom believed that they were likely or very likely to become infected with COVID-19. If infected, 17 (28.8%) believed that their illness would be serious or very serious. The top three strategies to cope with COVID-19 included acceptance, self-distraction, and use of emotional support. With respect to depression, anxiety, and stress, all of the mean scores were in the normal range. CONCLUSIONS: During COVID-19, residents in a southern community-based program with an academic affiliation reported effective coping strategies, predominantly acceptance, self-distraction, and use of emotional support. They reported concerns about becoming infected and, if they did, that their illness would likely be serious. Finally, they have not experienced depression, anxiety, or reported stress. The findings may be restricted in generalizability to a southern community-based program with an academic affiliation.

Background: The combination of amylase and lipase tests for diagnosing acute pancreatitis is not better than a lipase test alone; however, both tests are commonly ordered simultaneously. Further, although no data indicate usefulness of monitoring changes in elevated amylase and lipase levels, the tests are often ordered multiple times during the same clinical encounter. Methods: We retrospectively reviewed all amylase and lipase tests performed at a university-affiliated teaching hospital during a 6-month period. We considered amylase and lipase results diagnostic if they were >3 times the upper limit of normal and borderline if they were ≤3 times the upper limit of normal. During a single clinical encounter, we considered amylase tests superfluous if ordered simultaneously with lipase tests or repeated after diagnostic results, questionably superfluous if repeated alone, and nonsuperfluous otherwise. Lipase tests were considered superfluous if repeated after diagnostic results, questionably superfluous if repeated after nondiagnostic results, and nonsuperfluous otherwise. Results: In this study, 3,502 patients had 8,801 tests (4,926 lipase, 3,875 amylase), 4% of which were diagnostic and 10% borderline. Of the 8,801 tests, 45% were superfluous and 9% were questionably superfluous. Nonsuperfluous testing was less frequent (P<0.0001) in the intensive care/stepdown units (22% of 748 tests) than in the emergency department (54% of 6,000 tests) or other settings (31% of 2,053 tests). Among 3,545 simultaneous amylase/lipase tests with nondiagnostic lipase results, 0.6% amylase results were diagnostic. Of the 190 lipase tests repeated after nondiagnostic lipase results, 12% were diagnostic. Conclusion: Superfluous amylase/lipase testing in one teaching hospital is substantial, suggesting significant potential for reducing healthcare costs without compromising the quality of care when evaluating patients for acute pancreatitis.
ABSTRACT
INTRODUCTION: Educational milestones are now used to assess the developmental progress of all U.S. graduate medical residents during training. Twice annually, each program's Clinical Competency Committee (CCC) makes these determinations and reports its findings to the Accreditation Council for Graduate Medical Education (ACGME). The ideal way to conduct the CCC is not known. After finding that deliberations reliant upon the new milestones were time intensive, our internal medicine residency program tested an approach designed to produce rapid but accurate assessments. MATERIAL AND METHODS: For this study, we modified our usual CCC process to include pre-meeting faculty ratings of resident milestones progress with in-meeting reconciliation of their ratings. Data were considered largely via standard report and presented in a pre-arranged pattern. Participants were surveyed regarding their perceptions of data management strategies and use of milestones. Reliability of competence assessments was estimated by comparing pre-/post-intervention class rank lists produced by individual committee members with a master class rank list produced by the collective CCC after full deliberation. RESULTS: Use of the study CCC approach reduced committee deliberation time from 25 min to 9 min per resident (p < 0.001). Committee members believed milestones improved their ability to identify and assess expected elements of competency development (p = 0.026). Individual committee member assessments of trainee progress agreed well with collective CCC assessments. CONCLUSIONS: Modification of the clinical competency process to include pre-meeting competence ratings with in-meeting reconciliation of these ratings led to shorter deliberation times, improved evaluator satisfaction and resulted in reliable milestone assessments.
ABSTRACT
Cardiac papillary fibroelastomas (CPFs) are the second most common primary cardiac tumors and the most common cardiac valvular tumors. Although they are histologically benign and usually asymptomatic, CPFs can lead to serious and life-threatening complications like myocardial infarction, stroke, pulmonary embolus, cardiac arrest etc. CPFs represent a rare entity in clinical medicine and literature regarding their management is limited. We report two cases which illustrate such complications arising from undiagnosed CPFs on the aortic valve. We further stress on the importance of identifying CPFs early so that they can be managed appropriately based on recommendations from the available literature.
ABSTRACT
We aimed to determine the predictors of coronary artery disease (CAD) in patients with abnormal bilirubin excretion, that is, Gilbert syndrome, Crigler-Najjar syndrome, Dubin-Johnson syndrome, and Rotor syndrome. We analyzed data from the Healthcare Cost and Utilization Project (HCUP) of the Agency for Healthcare Research and Quality, Rockville, MD for the period 2009 to 2010. All patients ≥18 years of age with a primary diagnosis of "disorders of bilirubin excretion" [International Classification of Diseases, Ninth Edition, Clinical Modification (ICD-9CM) code 277.4] were included in the study. Primary outcome was to determine predictors of CAD in adult patients diagnosed with abnormal bilirubin excretion. We identified a total of 12,423 adult patients with bilirubin excretion disorder hospitalized during 2009-2010 (0.03% of all inpatient admissions). CAD was seen in 18% of patients, with a higher prevalence in men (21% in men vs. 13% in women, P < 0.0001). In multivariate logistic regression adjusted for demographic and traditional risk factors, hypertension [odds ratio (OR): 1.74; 95% confidence interval (CI), 1.33-2.27, P < 0.001], hyperlipidemia (OR: 2.49; 95% CI, 1.95-3.18, P < 0.001), diabetes (OR: 1.46; 95% CI, 1.12-1.91, P = 0.01), and age (OR: 1.05; 95% CI, 1.04-1.06, P < 0.001) were found to be independent predictors of CAD in adult patients with abnormal bilirubin excretion. Female sex (OR: 0.49; 95% CI, 0.36-0.65, P < 0.001) demonstrated an inverse association in predicting CAD. There was increased prevalence of CAD in our patient population with increased prevalence of cardiovascular risk factors. Age, diabetes mellitus, hypertension, and hyperlipidemia were found to be independent predictors of CAD.

Bilirubin has traditionally been considered a cytotoxic waste product. However, recent studies have shown bilirubin to have anti-oxidant, anti-inflammatory, vasodilatory, anti-apoptotic and anti-proliferative functions. These properties potentially confer bilirubin a new role of protection especially in coronary artery disease (CAD), which is a low grade inflammatory process exacerbated by oxidative stress. In fact, recent literature reports an inverse relationship between serum concentration of bilirubin and the presence of CAD. In this article, we review the current literature exploring the association between levels of bilirubin and risk of CAD. We conclude that current evidence is inconclusive regarding the protective effect of bilirubin on CAD. A causal relationship between low serum bilirubin level and increased risk of CAD is not currently established.
ABSTRACT
We investigated the etiologies of syncope and risk factors for mortality and rehospitalization for syncope at 17-month follow-up in a prospective study of 242 consecutive patients, mean age 69 years, hospitalized for syncope. The etiologies of syncope included the following: vasovagal syncope in 49 patients (20%), volume depletion in 39 patients (16%), orthostatic hypotension in 13 patients (5%), primary cardiac arrhythmias in 25 patients (10.3%), structural cardiac disease in 6 patients (2%), and drug overdose in 5 patients (2%). The etiology of syncope could not be determined in 84 patients (35%). Of the 242 patients, 6 (2%) were rehospitalized for syncope and 12 (5%) died. Stepwise logistic regression analysis showed that the significant independent prognostic factors for rehospitalization for syncope were drug overdose [odds ratio (OR): 11.506; 95% confidence interval (CI): 1.083-22.261]. Stepwise logistic regression analysis showed that significant independent prognostic factors for time to mortality were undetermined etiology of syncope (OR: 4.665; 95% CI: 1.002, 21.727), San Francisco Syncope Score (OR: 3.537; 95% CI: 1.472-8.496), hypertension (OR: 0.099; 95% CI: 0.019-0.504), and glomerular filtration rate (OR: 0.964; 95% CI: 0.937-0.993).

Sofosbuvir in combination with ribavirin was approved by the Food and Drug Administration as a treatment option for hepatitis C (HepC) in 2013. We describe a case of autoimmune hepatitis triggered in a patient on therapy with sofosbuvir and ribavirin. A 65-year-old woman with a medical history of diabetes mellitus, hypertension, and HepC (genotype 2) underwent pretreatment liver biopsy in May 2012, which demonstrated mild chronic active hepatitis with focal piece-meal necrosis and mild stage 1 periportal fibrosis with no increased iron deposition. No features of autoimmune hepatitis were seen on biopsy. The patient was administered 400 milligrams (mg) sofosbuvir and weight-based 1000 mg ribavirin for a planned duration of 12 weeks. Liver function tests (LFTs) initially improved on therapy; however, 3 weeks after the treatment initiation, the patient started complaining of weakness and fatigue. Repeat tests revealed elevated LFTs. Autoimmune titers were positive for antinuclear antibody, anti-smooth muscle antibody with elevated immunoglobulin (IgG), and serum gamma globulin levels. Repeat liver biopsy in June 2014 showed markedly distorted architecture secondary to formation of nodules completely enclosed by fibrous septa and areas of confluent necrosis with mild to moderate chronic inflammation consisting mainly of lymphocytes and plasma cells along with moderate to severe interface hepatitis. Ballooning degeneration of hepatocytes, with rosette formation possibly associated with regenerative activity was seen, consistent with superimposed autoimmune hepatitis. Based on laboratory and biopsy findings, diagnosis of drug-induced autoimmune hepatitis was made, and the treatment for HepC with sofosbuvir and ribavirin was discontinued. The patient was subsequently administered prednisolone with improvement in LFTs. We describe a patient with autoimmune hepatitis after initiation of sofosbuvir and ribavirin. To our knowledge, this complication has never been reported before in association with sofosbuvir. The most frequent adverse events noticed with this combination regimen have been headache, anemia, fatigue, and nausea.
ABSTRACT
Eosinophilic gastroenteritis (EG) is a rare disorder characterized by eosinophilic infiltration of the gastrointestinal tract. No medication at present is approved by the Food and drug administration of United States for the treatment of EG. The rarity of the disease limits our experience with the different management options. It also limits the ability to conduct randomized controlled trials that could clearly delineate the efficacy of new therapeutic agents. This review assesses the various management options that have been tried on patients with EG.

BACKGROUND: The association of chronic renal insufficiency with outcomes after percutaneous coronary intervention (PCI) in the current era of drug-eluting stents and modern antithrombotic therapy has not been well characterized. METHODS AND RESULTS: We queried the 2007-2011 Nationwide Inpatient Sample databases to identify all patients aged ≥18 years who underwent PCI. Multivariable logistic regression was used to compare in-hospital outcomes among patients with chronic kidney disease (CKD), patients with end-stage renal disease (ESRD), and those without CKD or ESRD. Of 3 187 404 patients who underwent PCI, 89% had no CKD/ESRD; 8.6% had CKD; and 2.4% had ESRD. Compared to patients with no CKD/ESRD, patients with CKD and patients with ESRD had higher in-hospital mortality (1.4% versus 2.7% versus 4.4%, respectively; adjusted odds ratio for CKD 1.15, 95% CI 1.12 to 1.19, P<0.001; adjusted odds ratio for ESRD 2.29, 95% CI 2.19 to 2.40, P<0.001), higher incidence of postprocedure hemorrhage (3.5% versus 5.4% versus 6.0%, respectively; adjusted odds ratio for CKD 1.21, 95% CI 1.18 to 1.23, P<0.001; adjusted odds ratio for ESRD 1.27, 95% CI 1.23 to 1.32, P<0.001), longer average length of stay (2.9 days versus 5.0 days versus 6.4 days, respectively; P<0.001), and higher average total hospital charges ($60 526 versus $77 324 versus $97 102, respectively; P<0.001). Similar results were seen in subgroups of patients undergoing PCI for acute coronary syndrome or stable ischemic heart disease. CONCLUSIONS: In patients undergoing PCI, chronic renal insufficiency is associated with higher in-hospital mortality, higher postprocedure hemorrhage, longer average length of stay, and higher average hospital charges.

BACKGROUND: Acute myocardial infarction is a recognized complication in patients with hypertrophic cardiomyopathy. However, limited data are available on outcomes of patients with hypertrophic cardiomyopathy and acute myocardial infarction. METHODS: We analyzed the 2003-2011 Nationwide Inpatient Sample databases to identify all patients aged ≥18 years with a principal diagnosis of acute myocardial infarction. Patients with a concomitant diagnosis of hypertrophic cardiomyopathy were then identified and analyzed as a separate cohort. Multivariate logistic regression was used to compare outcomes in patients with acute myocardial infarction with and without hypertrophic cardiomyopathy. RESULTS: Of 5,901,827 patients with acute myocardial infarction, 5688 (0.1%) had a diagnosis of hypertrophic cardiomyopathy. Patients with hypertrophic cardiomyopathy were older, more likely to be female, and less likely to have traditional cardiovascular risk factors. Compared with patients without hypertrophic cardiomyopathy, patients with hypertrophic cardiomyopathy were less likely to present with ST-elevation myocardial infarction and more likely to present with non-ST-elevation myocardial infarction. Patients with hypertrophic cardiomyopathy with ST-elevation myocardial infarction or non-ST-elevation myocardial infarction were less likely to receive revascularization. In the overall population with acute myocardial infarction, there was no difference in risk-adjusted in-hospital mortality between patients with and without hypertrophic cardiomyopathy (odds ratio [OR], 0.96; 95% confidence interval [CI], 0.84-1.11; P = .59). In the population with ST-elevation myocardial infarction, patients with hypertrophic cardiomyopathy had lower risk-adjusted in-hospital mortality than those without hypertrophic cardiomyopathy (OR, 0.75; 95% CI, 0.63-0.91; P = .003), whereas in the population with non-ST-elevation myocardial infarction, there was no difference in risk-adjusted in-hospital mortality between patients with and without hypertrophic cardiomyopathy (OR, 0.97; 95% CI, 0.84-1.11; P = .63). CONCLUSIONS: Patients with hypertrophic cardiomyopathy represent a small proportion of patients with acute myocardial infarction and are less likely to receive revascularization. Compared with patients without hypertrophic cardiomyopathy, patients with hypertrophic cardiomyopathy with ST-elevation myocardial infarction have lower risk-adjusted in-hospital mortality.

Acute myocardial infarction in patients with end-stage renal disease (ESRD) is associated with increased risk of morbidity and mortality. Limited data are available on the contemporary trends in management and outcomes of ST-elevation myocardial infarction (STEMI) in patients with ESRD. We analyzed the 2003 to 2011 Nationwide Inpatient Sample databases to examine the temporal trends in STEMI, use of mechanical revascularization for STEMI, and in-hospital outcomes in patients with ESRD aged ≥18 years in the United States. From 2003 to 2011, whereas the number of patients with ESRD admitted with the primary diagnosis of acute myocardial infarction increased from 13,322 to 20,552, there was a decrease in the number of STEMI hospitalizations from 3,169 to 2,558 (ptrend <0.001). The overall incidence rate of cardiogenic shock in patients with ESRD and STEMI increased from 6.6% to 18.3% (ptrend <0.001). The use of percutaneous coronary intervention for STEMI increased from 18.6% to 37.8% (ptrend <0.001), whereas there was no significant change in the use of coronary artery bypass grafting (ptrend = 0.32). During the study period, in-hospital mortality increased from 22.3% to 25.3% (adjusted odds ratio [per year] 1.09; 95% confidence interval 1.08 to 1.11; ptrend <0.001). The average hospital charges increased from $60,410 to $97,794 (ptrend <0.001), whereas the average length of stay decreased from 8.2 to 6.5 days (ptrend <0.001). In conclusion, although there have been favorable trends in the utilization of percutaneous coronary intervention and length of stay in patients with ESRD and STEMI, the incidence of cardiogenic shock has increased threefold, with an increase in risk-adjusted in-hospital mortality, likely because of the presence of greater co-morbidities.

BACKGROUND: Regional variation in the incidence and outcomes of in-hospital cardiac arrest (IHCA) is not well studied and may have important health and policy implications. METHODS AND RESULTS: We used the 2003 to 2011 Nationwide Inpatient Sample databases to identify patients≥18 years of age who underwent cardiopulmonary resuscitation (International Classification of Diseases, Ninth Edition, Clinical Modification procedure codes 99.60 and 99.63) for IHCA. Regional differences in IHCA incidence, survival to hospital discharge, and resource use (total hospital cost and discharge disposition among survivors) were analyzed. Of 838,465 patients with IHCA, 162,270 (19.4%) were in the Northeast, 159,581 (19.0%) were in the Midwest, 316,201 (37.7%) were in the South, and 200,413 (23.9%) were in the West. Overall IHCA incidence in the United States was 2.85 per 1000 hospital admissions. IHCA incidence was lowest in the Midwest and highest in the West (2.33 and 3.73 per 1000 hospital admissions, respectively). Compared with the Northeast, risk-adjusted survival to discharge was significantly higher in the Midwest (odds ratio, 1.33; 95% confidence interval, 1.31-1.36), South (odds ratio, 1.21; 95% confidence interval, 1.19-1.23), and West (odds ratio, 1.25; 95% confidence interval, 1.23-1.27). IHCA survival increased significantly from 2003 to 2011 in the United States and in all regions (all Ptrend<0.001). Total hospital cost was highest in the West, whereas discharge to skilled nursing facility and use of home health care among survivors was highest in the Northeast. CONCLUSIONS: We observed significant regional variation in IHCA incidence, survival, and resource use in the United States. This variation was explained only partially by differences in patient and hospital characteristics. Further studies are needed to identify other potential factors responsible for these regional differences to improve outcomes after IHCA.

BACKGROUND: The prevalence and contemporary trends of pre-heart transplantation (HT) coagulopathy and associated clinical outcomes have not been studied from a national database. HYPOTHESIS: Pre-HT coagulopathy is associated with increased in-hospital mortality. METHODS: Among 2454 adult HT recipients from the 2003 to 2010 Nationwide Inpatient Sample databases, 707 (29%) had pre-HT coagulopathy (defined as a comorbidity variable, based on International Classification of Diseases, Ninthe Revision, Clinical Modification and Diagnosis Related Group codes). We used propensity scores for coagulopathy to assemble a matched cohort of 664 pairs of patients with and without coagulopathy balanced in 54 baseline characteristics. RESULTS: The prevalence of pre-HT coagulopathy increased from 17% in 2003 to 44% in 2010 (P for trend <0.001). In-hospital mortality occurred in 8.6% and 4.7% of matched HT recipients with and without coagulopathy, respectively (hazard ratio: 1.81; 95% confidence interval [CI]: 1.17-2.80; P = 0.008). Coagulopathy was not significantly associated with post-HT graft complications (odds ratio [OR]: 1.20; 95% CI: 0.95-1.52; P = 0.131) but was associated with increased blood transfusions (OR: 1.92; 95% CI, 1.54-2.41; P < 0.001). Coagulopathy and no-coagulopathy groups had no difference in median length of stay (22 days in each group, P = 0.746), but median total hospital charges were higher among patients with coagulopathy compared to those without (US$425 643 vs US$389 656; P = 0.008). CONCLUSIONS: In this national study of HT recipients, pretransplant coagulopathy was common, increased over time, and was not significantly associated with post-HT graft complications or increased hospital stay. However, it was associated with increased bleeding risk, in-hospital mortality, and total hospital charges. These findings may have implications for the selection of patients for HT.

OBJECTIVES: The purpose of this study was to determine the association of complete heart block (CHB) with outcomes and to examine temporal trends in the incidence and outcomes of CHB complicating ST-segment elevation myocardial infarction (STEMI). BACKGROUND: There are limited data available on the incidence and outcomes of CHB in STEMI patients who undergo contemporary management. METHODS: We used the 2003 to 2012 National Inpatient Sample databases to identify all patients age ≥18 years hospitalized with STEMI. Patients with a concomitant diagnosis of CHB were then identified. Multivariable logistic regression was used to analyze the association of CHB with outcomes and to examine the temporal trends in incidence and outcomes of CHB complicating STEMI. RESULTS: Of 2,273,853 patients with STEMI, 49,882 (2.2%) had CHB. The incidence of CHB increased from 2.1% in 2003 to 2.3% in 2012 (adjusted odds ratio [OR] per year: 1.02; 95% confidence interval [CI]: 1.02 to 1.03). STEMI patients with CHB had higher in-hospital mortality than those without CHB (20.4% vs. 8.7%; adjusted OR: 2.47; 95% CI: 2.41 to 2.53). The higher mortality associated with CHB was independent of the location of STEMI; however, the magnitude of this association was greatest in patients with anterior STEMI. In patients with CHB complicating STEMI, although permanent pacemaker implantation rates declined (adjusted OR per year: 0.96; 95% CI: 0.95 to 0.97), in-hospital mortality remained unchanged during the study period (adjusted OR per year: 1.00; 95% CI: 0.99 to 1.01). CONCLUSIONS: The incidence of CHB complicating STEMI has increased slightly over the last decade, although the absolute incidence remains quite low. CHB remains associated with higher in-hospital mortality in STEMI patients even in the current era of prompt reperfusion therapy. In patients with CHB complicating STEMI, there was no change in risk-adjusted in-hospital mortality during the study period.
ABSTRACT
OBJECTIVES: Reporting of clinically significant events represents an important mechanism by which patient safety problems may be identified and corrected. However, time pressure and cumbersome report entry procedures have discouraged the full participation of physicians. To improve the process, our internal medicine training program developed an easy-to-use mobile platform that combines the reporting process with patient sign-out. METHODS: Between August 25, 2011, and January 25, 2012, our trainees entered clinically significant events into i-touch/i-phone/i-pad based devices functioning in wireless-synchrony with our desktop application. Events were collected into daily reports that were sent from the handoff system to program leaders and attending physicians to plan for rounds and to correct safety problems. RESULTS: Using the mobile module, residents entered 31 reportable events per month versus the 12 events per month that were reported via desktop during a previous 6-month study period. CONCLUSIONS: Advances in information technology now permit clinically significant events that take place during "off hours" to be identified and reported (via handoff) to next providers and to supervisors via collated reports. This information permits hospital leaders to correct safety issues quickly and effectively, while attending physicians are able to use information gleaned from the reports to optimize rounding plans and to provide additional oversight of trainee on call patient management decisions.

In-hospital cardiac arrest (IHCA) is common and is associated with poor prognosis. Data on the effect of smoking on outcomes after IHCA are limited. We analyzed the Nationwide Inpatient Sample databases from 2003 to 2011 for all patients aged≥18 years who underwent cardiopulmonary resuscitation (CPR) for IHCA to examine the differences in survival to hospital discharge and neurologic status between smokers and nonsmokers. Of the 838,464 patients with CPR for IHCA, 116,569 patients (13.9%) were smokers. Smokers were more likely to be younger, Caucasian, and male. They had a greater prevalence of dyslipidemia, coronary artery disease, hypertension, chronic pulmonary disease, obesity, and peripheral vascular disease. Atrial fibrillation, heart failure, and diabetes mellitus with complications were less prevalent in smokers. Smokers were more likely to have a primary diagnosis of acute myocardial infarction (14.8% vs 9.1%, p<0.001) and ventricular tachycardia or ventricular fibrillation as the initial cardiac arrest rhythm (24.3% vs 20.5%, p<0.001). Smokers had a higher rate of survival to hospital discharge compared with nonsmokers (28.2% vs 24.1%, adjusted odds ratio 1.06, 95% confidence interval 1.05 to 1.08, p<0.001). Smokers were less likely to have a poor neurologic status after IHCA compared with nonsmokers (3.5% vs 3.9%, adjusted odds ratio 0.92, 95% confidence interval 0.89 to 0.95, p<0.001). In conclusion, among patients aged ≥18 years who underwent CPR for IHCA, we observed a higher rate of survival in smokers than nonsmokers-consistent with the "smoker's paradox." Smokers were also less likely to have a poor neurologic status after IHCA.

INTRODUCTION: The aim of the study was to investigate predictors of mortality in patients hospitalized with hyperkalemia. MATERIAL AND METHODS: Data among hospitalized patients with hyperkalemia (serum potassium ≥ 5.1 mEq/l) were collected. Patients with end-stage renal disease on dialysis were excluded. RESULTS: Of 15,608 hospitalizations, 451 (2.9%) episodes of hyperkalemia occurred in 408 patients. In patients with hyperkalemia, chronic kidney disease, hypertension, diabetes, coronary artery disease and heart failure were common comorbidities. Acute kidney injury (AKI) and metabolic acidosis were common metabolic abnormalities, and 359 patients (88%) were on at least one drug associated with hyperkalemia. Mean duration to resolution of hyperkalemia was 12 ±9.9 h. Nonsteroidal anti-inflammatory drugs (HR = 1.59), highest potassium level (HR = 0.61), tissue necrosis (HR = 0.61), metabolic acidosis (HR = 0.77), and AKI (HR = 0.77) were significant independent determinants of duration prior to hyperkalemia resolution. Tissue necrosis (OR = 4.55), potassium supplementation (OR = 5.46), metabolic acidosis (OR = 4.84), use of calcium gluconate for treatment of hyperkalemia (OR = 4.62), AKI (OR = 3.89), and prolonged duration of hyperkalemia (OR = 1.06) were significant independent predictors of in-hospital mortality. CONCLUSIONS: Tissue necrosis, potassium supplementation, metabolic acidosis, calcium gluconate for treatment of hyperkalemia, AKI and prolonged duration of hyperkalemia are independent predictors of in-hospital mortality.
ABSTRACT
BACKGROUND: Limited information is available on the contemporary and potentially changing trends in the incidence, management, and outcomes of cardiogenic shock complicating ST-elevation myocardial infarction (STEMI). METHODS AND RESULTS: We queried the 2003-2010 Nationwide Inpatient Sample databases to identify all patients ≥ 40 years of age with STEMI and cardiogenic shock. Overall and age-, sex-, and race/ethnicity-specific trends in incidence of cardiogenic shock, early mechanical revascularization, and intra-aortic balloon pump use, and inhospital mortality were analyzed. From 2003 to 2010, among 1 990 486 patients aged ≥ 40 years with STEMI, 157 892 (7.9%) had cardiogenic shock. The overall incidence rate of cardiogenic shock in patients with STEMI increased from 6.5% in 2003 to 10.1% in 2010 (P(trend)<0.001). There was an increase in early mechanical revascularization (30.4% to 50.7%, P(trend)<0.001) and intra-aortic balloon pump use (44.8% to 53.7%, P(trend)<0.001) in these patients over the 8-year period. Inhospital mortality decreased significantly, from 44.6% to 33.8% (P(trend)<0.001; adjusted OR, 0.71; 95% CI, 0.68 to 0.75), whereas the average total hospital cost increased from $35 892 to $45 625 (P(trend)<0.001) during the study period. There was no change in the average length of stay (P(trend)=0.394). These temporal trends were similar in patients <75 and ≥ 75 years of age, men and women, and across each racial/ethnic group. CONCLUSIONS: The incidence of cardiogenic shock complicating STEMI has increased during the past 8 years together with increased use of early mechanical revascularization and intra-aortic balloon pumps. There has been a concomitant decrease in risk-adjusted inhospital mortality, but an increase in total hospital costs during this period.
