Abstract
BACKGROUND Short bowel syndrome (SBS) hospitalizations are often complicated with sepsis. There is a significant paucity of data on adult SBS hospitalizations in the United States and across the globe.
AIM To assess trends and outcomes of SBS hospitalizations complicated by sepsis in the United States.
METHODS The National Inpatient Sample was utilized to identify all adult SBS hospitalizations between 2005-2014. The study cohort was further divided based on the presence or absence of sepsis. Trends were identified, and hospitalization characteristics and clinical outcomes were compared. Predictors of mortality for SBS hospitalizations complicated with sepsis were assessed.
RESULTS Of 247097 SBS hospitalizations, 21.7% were complicated by sepsis. Septic SBS hospitalizations had a rising trend of hospitalizations from 20.8% in 2005 to 23.5% in 2014 (P trend < 0.0001). Compared to non-septic SBS hospitalizations, septic SBS hospitalizations had a higher proportion of males (32.8% vs 29.3%, P < 0.0001), patients in the 35-49 (45.9% vs 42.5%, P < 0.0001) and 50-64 (32.1% vs 31.1%, P < 0.0001) age groups, and ethnic minorities, i.e., Blacks (12.4% vs 11.3%, P < 0.0001) and Hispanics (6.7% vs 5.5%, P < 0.0001). Furthermore, septic SBS hospitalizations had a higher proportion of patients with intestinal transplantation (0.33% vs 0.22%, P < 0.0001), inpatient mortality (8.5% vs 1.4%, P < 0.0001), and mean length of stay (16.1 d vs 7.7 d, P < 0.0001) compared to the non-sepsis cohort. A younger age, female gender, White race, and presence of comorbidities such as anemia and depression were identified to be independent predictors of inpatient mortality for septic SBS hospitalizations.
CONCLUSION Septic SBS hospitalizations had a rising trend between 2005-2014 and were associated with higher inpatient mortality compared to non-septic SBS hospitalizations.

Abstract
Introduction Pulmonary symptoms are the most prominent manifestations of Coronavirus disease 2019 (COVID-19). However, gastrointestinal (GI) symptoms have been reported widely as well. Literature describing the relation of these symptoms with outcomes of COVID-19 patients is limited in terms of sample size, geographic diversity, and the spectrum of GI symptoms included. We aim to evaluate the association of GI symptoms with outcomes of hospitalized COVID-19 patients. Methods A systematic review and meta-analysis of observational studies assessing GI symptoms and outcomes in COVID-19 patients were undertaken using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria and the Meta-analysis of Observational Studies in Epidemiology (MOOSE) checklist. Details on outcomes included ICU vs. non-ICU admission, severe vs. non-severe disease, invasive mechanical ventilation (IMV) vs. no-IMV use, oxygen saturation <90% vs. >90%, in-hospital mortality vs. discharged alive and survivors. We obtained the odds ratio (OR), 95% confidence interval (95%CI), and forest plots. Sensitivity analysis was used to analyze publication bias and heterogeneity. Results In 35 studies with 7931 confirmed COVID-19 patients, we found that anorexia (pooled OR:2.05; 95%CI: 1.36-3.09, p=0.0006) and abdominal pain (OR 2.80; 95%CI: 1.41-5.54, p=0.003) were associated with a higher risk of poor outcomes and no such association was found for diarrhea (OR 1.04; 95%CI: 0.85-1.26, p=0.71), nausea (OR 0.73; 95%CI: 0.38-1.39, p=0.34) and vomiting (OR 1.24; 95%CI 0.86-1.79, p=0.25). Conclusion The meta-analysis concludes that anorexia and abdominal pain are associated with poor outcomes in hospitalized COVID-19 patients, while diarrhea, nausea, and vomiting have no association. Future research should focus on whether detecting GI invasion in conjunction with fecal polymerase chain reaction (PCR) testing can aid in the early triage of high-risk individuals and improve outcomes.

Abstract
Background With the advent of novel treatments, there is a declining trend in the multiple myeloma (MM) mortality rate with an increasing hospitalization rate. However, there is limited population-based data on trends and outcomes of hospitalizations due to MM in the United States (US). Methods We analyzed the publicly available Nationwide Inpatient Sample (NIS) from 2007 to 2017 to identify MM hospitalizations. Results Hospitalizations for MM increased from 17,100 (8.71%) in 2007 to 19,490 (9.92%) in 2017. The in-hospital mortality rate declined from 8.4% in 2007 to 4.9% in 2017 (P <0.001) and discharge to facilities decreased from 20.4% in 2007 to 17.4% in 2017 (P <0.001). The odds of in-hospital mortality were higher with increasing age (odds ratio (OR): 1.46; 95% confidence interval (CI): 1.38 -1.54; P <0.0001), pneumonia (OR: 4.18; 95% CI: 3.63 - 4.81, P <0.0001), septicemia (OR: 2.50; 95% CI: 2.22 - 2.82; P <0.0001), renal failure (OR: 1.48; 95% CI: 1.34 -1.64; P <0.0001), uninsured/self-pay insurance status (OR: 2.69; 95% CI: 2.18 - 3.3; P <0.0001), rural hospital (OR: 2.26; 95% CI: 1.88 -2.72; P<0.0001), and urban-non-teaching hospitals (OR: 1.38; 95% CI: 1.23 - 1.56; P <0.0001). Also, increasing age (OR: 1.14; 95% CI: 1.11-1.18, P <0.0001), Black race (OR: 1.12; 95% CI: 1.02-1.23, P <0.0001), and multiple comorbidities were associated with higher disability. Conclusion Hospitalizations for MM continued to increase, whereas in-hospital mortality continued to decrease. Advanced age, sepsis, pneumonia, and renal failure were associated with higher odds of mortality in MM patients.

Abstract
Large-scale multi-hospital data on cardiac resynchronization therapy (CRT) device implantation in patients with chronic kidney disease (CKD) are currently lacking. The purpose of this study was to examine the incidence of CRT device implantation in patients hospitalized with CKD and the impact of CRT device implantation on hospital complications and outcomes. We analyzed the Nationwide Inpatient Sample from 2008-2014 to identify yearly trends in CRT device implantation during CKD hospitalizations. We compared CRT biventricular pacemakers (CRT-Ps) and CRT defibrillators (CRT-Ds). We also obtained rates of comorbidities and complications associated with CRT device implantations. From 2008-2014, the proportion of hospitalized patients with a concurrent diagnosis of CKD receiving CRT-P devices consistently went up from 2008 to 2014 (from 12.3% to 23.8%, P < .0001) compared to the number of hospitalized patients with a concurrent diagnosis of CKD receiving CRT-D devices, which showed a consistent downward trend (from 87.7% to 76.2%, P < .0001). During CKD hospitalizations, most CRT device implantations were performed in patients aged 65-84 years (68.6%) and in men (74.3%). The most common complication of CRT device implantation during hospitalizations involving CKD was hemorrhage or hematoma (2.7%). Patients hospitalized with CKD who developed any complication associated with CRT device implantation had 3.35-fold increased odds of mortality compared to those without complications (odds ratio, 3.35; 95% confidence interval, 2.18-5.16; P < .0001). In summary, this study shows that CRT-P implantations became more common in CKD patients, while the rate of CRT-D implantations decreased over time. Hemorrhage or hematoma was the most common complication (2.7%), and the mortality risk was increased by 3.35 times in patients who developed periprocedural complications.

Abstract
Background Clostridium difficile infection (CDI) is one of the rising public health threats in the United States. It has imposed significant morbidity and mortality in the elderly population. However, the burden of the disease in the young population is unclear. This study aimed to identify hospitalization trends and outcomes of CDI in the young population. Methodology We obtained data from the National (Nationwide) Inpatient Sample (NIS) for hospitalizations with CDI between 2007 and 2017. We used the International Classification of Diseases Ninth Edition-Clinical Modification (ICD-9-CM) and ICD-10-CM to identify CDI and other diagnoses of interest. The primary outcome of our study was to identify the temporal trends and demographic characteristics of patients aged less than 50 years old hospitalized with CDI. The secondary outcomes were in-hospital mortality, length of hospital stay (LOS), and discharge dispositions. We utilized the Cochran Armitage trend test and multivariable survey logistic regression models to analyze the trends and outcomes. Results From 2007 to 2017, CDI was present among 1,158,047 hospitalized patients. The majority (84.04%) of the patients were ≥50 years old versus 15.95% of patients <50 years old. From 2007 to 2017, there was a significant increase in CDI among <50-year-old hospitalized patients (12.6% from 2007 to 18.1% in 2017; p < 0.001). In trend analysis by ethnicities, among patients <50 years old, there was an increasing trend in Caucasians (63.9% versus 67.9%; p < 0.001) and Asian females (58.4% versus 62.6%; p < 0.001). We observed an increased trend of discharge to home (91.3% vs 95.8%; p < 0.001) in association with a decrease in discharge to facility (8.3% vs 4%; p < 0.001). The average LOS from 2007 to 2017 was 5 ± 0.03 days, which remained stable during the study period. Conclusions The proportion of young (<50 years old) hospitalized patients with CDI has been steadily increasing over the past decade. Our findings might represent new epidemiological trends related to non-traditional risk factors. Future CDI surveillance should extend to the young population to confirm our findings, and the study of emerging risk factors is required to better understand the increasing CDI hospitalization in the young population.

Abstract
GOALS We aimed to assess outcomes of patients with liver cirrhosis who underwent therapeutic or diagnostic endoscopic retrograde cholangiopancreatography (ERCP) to determine whether these patients had different outcomes relative to patients without cirrhosis. BACKGROUND ERCP is an important procedure for treatment of biliary and pancreatic disease. However, ERCP is relatively technically difficult to perform when compared with procedures such as esophagogastroduodenoscopy or colonoscopy. Little is known about how ERCP use affects patients with liver cirrhosis. STUDY Using patient records from the National Inpatient Sample (NIS) database, we identified adult patients who underwent ERCP between 2009 and 2014 using International Classification of Disease, Ninth Revision coding and stratified data into 2 groups: patients with liver cirrhosis and those without liver cirrhosis. We compared baseline characteristics and multiple outcomes between groups and compared outcomes of diagnostic versus therapeutic ERCP in patients with cirrhosis. A multivariate regression model was used to estimate the association of cirrhosis with ERCP outcomes. RESULTS A total of 1,038,258 hospitalizations of patients who underwent ERCP between 2009 and 2014 were identified, of which 31,294 had cirrhosis and 994,681 did not have cirrhosis. Of the patients with cirrhosis, 21,835 (69.8%) received therapeutic ERCP and 9459 (30.2%) received diagnostic ERCP. Patients with cirrhosis had more ERCP-associated hemorrhages (2.5% vs. 1.2%; P <0.0001) compared with noncirrhosis patients but had lower incidence of perforations (0.1% vs. 0.2%; P <0.0001) and post-ERCP pancreatitis (8.6% vs. 7%; P <0.0001). Cholecystitis was the same between groups (2.3% vs. 2.3%; P <0.0001). In patients with cirrhosis, those who received therapeutic ERCP had higher post-ERCP pancreatitis (7.9% vs. 5.1%; P <0.0001) and ERCP-associated hemorrhage (2.7% vs. 2.1%; P <0.0001) but lower incidences of perforation and cholecystitis (0.1% vs. 0.3%; P <0.0001) and cholecystitis (1.9 vs. 3.1%; P <0.0001) compared with those who received diagnostic ERCP. CONCLUSIONS Use of therapeutic ERCP in patients with liver cirrhosis may lead to higher risk of complications such as pancreatitis and postprocedure hemorrhage, whereas diagnostic ERCP may increase the risk of pancreatitis and cholecystitis in patients with cirrhosis. Comorbidities in cirrhosis patients may increase the risk of post-ERCP complications and mortality; therefore, use of ERCP in cirrhosis patients should be carefully considered, and further studies on this patient population are needed.

Abstract
Background This retrospective study was conducted to analyze the temporal trends, predictors, and impact of disseminated intravascular coagulation (DIC) on outcomes among septicemic patients using a nationally representative database. Methods We derived data from the National Inpatient Sample (NIS) for the years 2008-2017 for adult hospitalizations due to sepsis. The primary outcomes were in-hospital mortality and discharge to facility. The Cochran-Armitage test and multivariable survey logistic regression models were used to analyze the data. Results Out of 12,820,000 hospitalizations due to sepsis, 153,181 (1.18%) were complicated by DIC. The incidence of DIC decreased from 2008 to 2017. In multivariable regression analysis, demographics and comorbidities were associated with higher odds of DIC. During the study period, in-hospital mortality among patients with sepsis decreased, but the attributable risk percent of in-hospital mortality due to DIC increased. We observed similar trends for discharge to facility; however, the adjusted odds of discharge to facility due to DIC remained stable over the study period. Conclusion Although the incidence of sepsis complicated by DIC decreased, the attributable in-hospital mortality rate due to DIC increased during the study period. We identified several predictors associated with the development of DIC in sepsis, some of which are potentially modifiable.

Abstract
BACKGROUND/OBJECTIVES Pancreatic cancer is the third leading cause of cancer death in the United States (US). However, there is paucity of data on pancreatic cancer hospitalizations in the US. METHODS We analyzed the National Inpatient Sample (NIS) to identify all hospitalizations of pancreatic cancer from 2008 to 2017. Hospitalization characteristics, adverse outcomes, and the disease burden on the US healthcare system was highlighted and further analyzed with respect to the US population. P-values ≤0.05 were statistically significant. RESULTS We noted an increase in the total number of pancreatic cancer hospitalizations from 37,123 in 2008 to 37,635 in 2017 (p < 0.0001), but a decline was noted for per million US population from 122 in 2008 to 116 in 2017. The 65-79 age group had the highest hospitalizations with an increasing trend from 41.6% in 2008 to 45.9% in 2017 (p < 0.0001). In 2008, a slight female predominance was noted (51.9 vs 48.1%, p < 0.0001); however, in 2017, a slight male predominance was observed (50.9 vs 49.1%, p < 0.0001). Whites made up a majority of the study population. Furthermore, emergent/urgent hospitalizations (50.7 vs 49.3%, p < 0.0001) were slightly more frequent than elective hospitalizations in 2017. The mean length of stay (LOS) decreased from 8.4 days in 2008 to 7 days in 2017 (p < 0.0001) and the all-cause inpatient mortality decreased from 10.1% in 2008 to 7.6% in 2017 (p < 0.0001). CONCLUSION Although the total number of pancreatic cancer hospitalizations increased, there was a decline for per million US population. Additionally, mean LOS and inpatient mortality decreased between 2008 and 2017.

Abstract
Background Hidradenitis suppurativa (HS) is a clinical condition characterized by the formation of painful lumps under the skin. It often affects intertriginous areas like armpits and groin. There is a paucity of contemporary data on patient and hospital-level characteristics of HS in the United States. Methods We analyzed the Nationwide Inpatient Sample (NIS) for retrospective analysis to calculate the frequency and yearly rates of HS hospitalizations, demographic variations, rates of comorbidities, and length of stay. Results The rate of hospitalizations with HS as a primary diagnosis increased from 7.9 per 100,000 all-cause hospitalizations in 2008 to 11.6 per 100,000 all-cause hospitalizations in 2017 (p < 0.0001). The mean age ± standard error of hospitalized patients was 39.5 ± 0.2 years. The age group of 18-34 years was the most affected. Women showed a higher preponderance of the disease than men (56.6% vs. 43.5%, p < 0.0001). The Black race was the most affected out of all the racial groups (59.9%). Most hospitalizations were in large, urban teaching hospitals. Hypertension (34.9%), skin and subcutaneous tissue infections (26.5%), and diabetes mellitus (25.9%) were the most common comorbidities. Out of the total hospitalizations with HS, 12.7% were found to have a major or extreme loss of function and 3.5% were at a major or extreme likelihood of dying. Conclusions HS disproportionately affects young adults, women, and Black patients. A significant proportion of these patients are at a major risk of major loss of bodily function or death. Prospective studies are needed to identify the risk factors for hospitalizations in these patient populations and devise appropriate prevention and treatment strategies.

Abstract
BACKGROUND Alcoholic liver cirrhosis (ALC) is a chronic liver disease with varying disease severity. Readmissions of ALC are associated with poor outcomes.
AIM To identify and assess trends of readmissions for ALC over an eight-year period.
METHODS This retrospective interrupted trend study analysed 30-d readmissions of ALC in the United States from 2010 to 2018 using the National Readmissions Database. Hospitalization for ALC was the reason for index admission obtained using the International Classification of Diseases codes (571.2 and K70.3X). Biodemographic characteristics and hospitalization trends were highlighted over time. A multivariate regression analysis model was used to calculate the trend for risk-adjusted odds of 30-d all-cause ALC readmissions, ALC specific readmission rate, ALC readmission proportion, inpatient mortality, mean length of stay (LOS) and mean total hospital cost (THC) following adjustments for age, gender, grouped Charlson Comorbidity Index, insurance, mean household income, and hospital characteristics.
RESULTS There was a trend towards increasing total 30-d readmissions of ALC from 7660 in 2010 to 15085 in 2018 (P < 0.001). Patients readmitted for ALC were noted to have an increasing comorbidity burden over time. We noted a rise in the risk-adjusted 30-d all-cause readmission of ALC from 24.9% in 2010 to 29.9% in 2018 (P < 0.001). ALC-specific readmission rate increased from 6.3% in 2010 to 8.4% in 2018 (P < 0.001) while ALC readmission proportion increased from 31.4% in 2010 to 36.3% in 2018 (P < 0.001). Inpatient mortality for 30-d readmissions of ALC declined from 10.5% in 2010 to 8.2% in 2018 (P = 0.0079). However, there was a trend towards increasing LOS from 5.6 d in 2010 to 6.3 d in 2018 (P < 0.001) and increasing THC from 13790 dollars in 2010 to 17150 dollars in 2018 (P < 0.001). The total days of hospital stay attributable to 30-d readmissions of ALC increased by 119.2% while the total attributable hospital costs increased by 149% by the end of 2018.
CONCLUSION There was an increase in the 30-d readmission rate and comorbidity burden for ALC; however, inpatient mortality declined. Additionally, there was a trend towards increasing LOS and THC for these readmissions.

Abstract
Type 2 myocardial infarction (Type 2 MI) is a common problem and carries a high diagnostic uncertainty. Large studies exploring outcomes in type 2 MI are lacking. Nationwide Readmission Database (2017) was queried using the International Classification of Diseases codes (ICD-10-CM) to identify type 2 MI patients. Characteristics, in-hospital outcomes, 30-day readmissions, and predictors of in-hospital mortality as well as 30-day readmissions were explored. We identified 21,738 patients with a diagnosis of type 2 MI. Most common primary diagnosis at presentation included infection/sepsis (27.5%), hypertensive heart disease (15.3%) and pulmonary diseases (8.5%). Overall, in-hospital mortality and 30-day readmission for patients with type 2 MI were 9.0% and 19.1% respectively. On multivariable analysis, significant predictors of increased in-hospital mortality included male gender, coexisting atrial fibrillation/flutter, peripheral vascular disease, coagulopathy, malignancy, and fluid/electrolyte abnormalities. Significant predictors of 30-day readmission were coexisting diabetes mellitus, atrial fibrillation/ flutter, carotid artery stenosis, anemia, COPD, CKD and prior history of myocardial infarction, A primary diagnosis of sepsis, pulmonary issues including respiratory failure, neurological conditions including stroke carried highest risk of mortality however readmission risk was not influenced by primary diagnosis at presentation. In conclusion, approximately 1 in 10 patients admitted for type 2 MI died during admission, and nearly 1 in 5 patients were readmitted at 30 days after discharge. In-hospital mortality varied based on associated primary diagnosis at presentation. Proposed predictive model for mortality and 30-day readmission in our study can help to target high risk patients for post-Type 2 MI care.

Abstract
Objective Robotically assisted PCI offers a great alternative to S–PCI. This has gained even more relevance during the COVID-19 pandemic era however safety of R–PCI compared to S–PCI has not been studied well. This study explores the safety and efficacy of robotically assisted PCI (R–PCI) compared to standard PCI (S–PCI) for the treatment of coronary artery disease (CAD). Methods PubMed, Scopus, Ovid, and Google scholar databases were searched for studies comparing R–PCI to S–PCI. Outcomes included clinical success, procedure time, fluoroscopy time, contrast use and radiation exposure. Results Theauthors included 5 studies comprising 1555 patients in this meta-analysis. Clinical success was comparable in both arms (p = 0.91). Procedure time was significantly longer in R–PCI group (risk ratio: 5.52, 95% confidence interval: 1.85 to 9.91, p = 0.003). Compared to S–PCI, patients in R–PCI group had lower contrast use (meandifference: −19.88, 95% confidence interval: −21.43 to −18.33, p < 0.001), fluoroscopy time (mean difference:-1.82, 95% confidence interval: −3.64 to −0.00, p = 0.05) and radiation exposure (mean difference:-457.8, 95% confidence interval: −707.14 to −208.14, p < 0.001). Conclusion R–PCI can achieve similar success as S–PCI at the expense of longer procedural times. However, radiation exposure and contrast exposure were lower in the R–PCI arm.

Abstract
Background: With increasing utilization of cannabis in the United States (US), clinicians may encounter more cases of Gastroparesis (GP) in coming years.Objective: The primary outcome was inpatient mortality for GP with cannabis use. Secondary outcomes included system-based complications and the burden of the disease on the US healthcare system.Methods: From the Nationwide Inpatient Sample (NIS), we identified adult hospitalizations with a primary discharge diagnosis of GP for 2016 and 2017. Individuals ≤18 years of age were excluded. The study population was subdivided based on a secondary diagnosis of cannabis use. The outcomes included biodemographic characteristics, mortality, complications, and burden of disease on the US healthcare system.Results: For 2016 and 2017, we identified 99,695 hospitalizations with GP. Of these hospitalizations, 8,870 had a secondary diagnosis of cannabis use while 90,825 served as controls. The prevalence of GP with cannabis use was 8.9%. For GP with cannabis use, the patients were younger (38.5 vs 48.1 years, p < 0.001) with a Black predominance (Table 1) and lower proportion of females (52.3 vs 68.3%, p < 0.001) compared to the non-cannabis use cohort. Additionally, the cannabis use cohort had higher percentage of patients with co-morbidities like hypertension, diabetes mellitus and a history of smoking. The inpatient mortality for GP with cannabis use was noted to be 0.27%. Furthermore, we noted shorter mean length of stay (LOS) (3.4 vs 4.4 days, aMD: -0.7, 95%CI: -0.9 - [-0.5], p < 0.001), lower mean total hospital charge (THC) ($30,400 vs $38,100, aMD: -5100, 95%CI: -6900 - [-3200], p < 0.001), and lower rates of sepsis (0.11 vs 0.60%, aOR: 0.22, 95% CI: 0.05-0.91, p = 0.036) for GP hospitalizations with cannabis use compared to the non-cannabis use cohort.Conclusion: Inpatient mortality for GP hospitalizations with cannabis use was 0.27%. Additionally, these patients had shorter LOS, lower THC, and lower sepsis rates.

Abstract
Background: It is well-known that patients with chronic kidney disease and end-stage
renal disease are at increased risk of pulmonary embolism than patients with
normal kidney function. However, the data on trends, outcomes, and
predictors of mortality in pulmonary embolism patients with chronic kidney
disease and end-stage renal disease in the United States are limited. Methods: We queried the National Inpatient Sample database from 2010 to 2014.
International Classification of Diseases-Ninth Revision-Clinical
Modification codes were used to identify patients with normal kidney
function, chronic kidney disease, and end-stage renal disease. The frequency
of pulmonary embolism, complications, in-hospital mortality, and length of
stay were calculated for each cohort. Multivariable logistic regression
models were constructed to determine the predictors of mortality. Results: In the study population (2010–2014), there were 766,176 pulmonary embolism
hospitalizations with normal kidney function, 79,824 with chronic kidney
disease, and 9147 with end-stage renal disease. Among the study cohorts, the
mortality rate was 2.7% in normal kidney function, 4.5% in chronic kidney
disease, and 6.8% in end-stage renal disease hospitalizations. Median length
of stay was highest in the end-stage renal disease cohort and lowest in the
normal kidney function cohort. After adjusting for confounders, pulmonary
embolism patients with chronic kidney disease died 1.15 times more often
than those with normal kidney function and pulmonary embolism patients with
end-stage renal disease died 4.2 times more often than those with normal
kidney function. Conclusion: The mortality rate and length of stay in pulmonary embolism patients with
chronic kidney disease and end-stage renal disease were significantly higher
than those in pulmonary embolism patients with normal kidney function. Also,
pulmonary embolism patients with chronic kidney disease and end-stage renal
disease were at higher risk of in-hospital mortality than those with normal
kidney function. There was statistically significant higher risk of
mortality in elderly and Black patients with pulmonary embolism and
concurrent chronic kidney disease or end-stage renal disease.

Abstract
Background/Aims Proinflammatory cytokines released from adipocytes can influence the development, progression, and treatment of inflammatory bowel disease (IBD), and may be associated with worse clinical outcomes. Methods For 2016–2018, we analyzed data from the Nationwide Inpatient Sample to identify adult (≥18 years) hospitalizations with a primary discharge diagnosis of IBD. The study sample was divided based on the presence or absence of obesity. The primary outcomes included inpatient mortality, while the secondary outcomes consisted of system-based complications and disease implications on the United States healthcare system. Results We identified 282,005 hospitalizations of IBD from 2016 to 2018. Of these hospitalizations, 26,465 (9.4%) had a secondary diagnosis of obesity while 255,540 (90.6%) served as controls. IBD hospitalizations with obesity had a higher mean age (47.9 years vs. 45.2 years, P<0.001), middle age (range, 40–65 years) predominance (37.7% vs. 28.9%, P<0.001), female predominance (64.1% vs. 52.5%, P<0.001) and higher proportion of patients with comorbidities compared to the non-obese cohort. White predominance was observed in both subgroups. No difference in the odds of inpatient mortality was noted between the 2 subgroups; however, IBD hospitalizations with obesity had higher mean total hospital charge ($50,126 vs. $45,001, P<0.001), longer length of stay (5.5 days vs. 4.9 days, P<0.001) and higher proportion of complications compared to the non-obese cohort. Conclusions Obese IBD hospitalizations had higher length of stay, total hospital charge, and complications compared to the non-obese cohort.

Abstract
Background Gastric antral vascular ectasia (GAVE) syndrome is a rare but significant cause of acute or chronic gastrointestinal (GI) bleeding, particularly in the elderly. The primary objective of this study was to determine the biodemographic characteristics, adverse outcomes, and the impact of GAVE hospitalizations on the US healthcare system. Methods This retrospective database cross-sectional study used the National Inpatient Sample (NIS) from 2001 to 2011 to identify all adult hospitalizations with a primary discharge diagnosis of GAVE, with and without hemorrhage, using the International Classification of Diseases, Ninth Revision (ICD-9) codes. Individuals less than 17 years of age were excluded from the study. The outcomes included biodemographic characteristics, comorbidity measures, and inpatient mortality and the burden of the disease on the US healthcare system in terms of healthcare cost and utilization. Results We noted an increase in the total hospitalizations for GAVE from 25,423 in 2001 to 44,787 in 2011. Furthermore, GAVE hospitalizations with hemorrhage rose from 19,168 in 2001 to 27,679 in 2011 while GAVE hospitalization without hemorrhage increased from 6,255 in 2001 to 17,108 in 2011. We also noted a female predominance, the proportional trend of which did not show significant difference from 2001 to 2011. For GAVE hospitalizations, the inpatient mortality decreased from 2.20% in 2001 to 1.73% in 2011. However, the cost of hospitalization increased from $11,590 in 2001 to $12,930 in 2011. After adjusting for possible confounders, we observed that the presence of hemorrhage in GAVE hospitalizations was associated with an increased risk of mortality (odds ratio (OR): 1.27; 95% confidence interval (CI): 1.1 - 1.46; P = 0.001). Conclusions For the study period, the total number of GAVE hospitalizations increased with an increase noted in the proportion of GAVE hospitalizations without bleeding, reflecting an improvement in diagnostic and therapeutic techniques. Although inpatient mortality for GAVE slightly decreased, we noted a significant increase in the cost of care likely secondary to increased use of advanced and expensive interventions.

Abstract
Background There is a paucity of contemporary national estimates for Clostridium difficile infection (CDI) hospitalizations by age group, sex, and region in the US population. Also, there is lack of contemporary national statistics on CDI hospitalizations with comorbidities. Methods We analyzed the 2017 National Inpatient Sample (NIS) to determine the population-based rates of CDI hospitalizations, characteristics of hospitalizations with CDI, and the rates of comorbidities associated with CDI hospitalizations. Results There were 329,460 CDI-related hospitalizations in 2017 (almost 1% of all hospitalizations). The average age for patients admitted with CDI as a principal or secondary diagnosis was 64.7 years (almost 20 years older when compared with all other hospitalizations). Patients 85 years and older had the highest rate of CDI hospitalizations (716 per 100,000 hospitalizations), and patients less than 18 years of age had the lowest rate (12 per 100,000 hospitalizations). There was a progressive increase in the CDI hospitalization rates with each successive age group. The hospitalization rates were higher in females (114 per 100,000 hospitalizations) than males (88 per 100,000 hospitalizations). The CDI hospitalization rate was highest in the Northeast (109 per 100,000 hospitalizations) and lowest in the West (84 per 100,000 hospitalizations). Fluid and electrolyte disturbance (63.3%) and renal failure (33.4%) were the two most common comorbidities associated with CDI hospitalizations. When CDI is a secondary diagnosis, major loss of function, extreme likelihood of dying, septicemia, and septic shock were more common in comparison to CDI as a principal diagnosis. Conclusions CDI hospitalization rates were highest in the elderly over 85 years old and declined with successive decreases in age. Women had higher CDI hospitalization rates than men, and fluid and electrolyte disturbances and renal failure were the most common comorbid conditions. The presence of CDI as a comorbid condition at the time of hospitalization for other principal diagnoses or development of CDI during a hospitalization for other principal diagnoses significantly increases the risk of in-hospital morbidity and mortality.

Abstract
Clostridium difficile is a gram-positive anaerobic spore forming bacillus that can cause infection in a setting of antibiotic use. Pneumonia is a major cause of morbidity and mortality in an inpatient setting and is frequently associated with significant antibiotic administration. This study aims to compare the outcomes of C. difficile infection (CDI) with and without pneumonia to determine the impact of pneumonia in hospitalized patients with CDI. This population-based retrospective observational propensity matched analysis study uses data from the National Inpatient Sample database for the years 2016 and 2017. The primary outcomes were in-hospital mortality, total hospital charges, and mean length of stay. Secondary outcomes were the rates of sepsis, septic shock, non-ST elevation myocardial infarction (NSTEMI), acute renal failure, deep vein thrombosis, and pulmonary embolism. In-hospital mortality was noted to be higher in patients with pneumonia than those without (6.5% vs 1.2%, adjusted OR (aOR) 3.85; 95% CI 2.90 to 5.11, p<0.001). The following outcomes were more prevalent in patients with pneumonia compared with those without pneumonia: sepsis (9.8% vs 1.8%, aOR 4.69, 95% CI 3.73 to 5.87, p<0.001), septic shock (4.0% vs 0.5%, aOR 6.32, 95% CI 4.43 to 9.03, p<0.001), NSTEMI (1.9% vs 0.5%, aOR 2.95, 95% CI 1.85 to 4.71, p<0.001), and acute renal failure (31.5% vs 23.1%, aOR 1.23, 95% CI 1.07 to 1.40, p=0.003). In conclusion, patients with pneumonia were associated with significantly higher rates of system-based complications and higher in-hospital mortality rates.

Abstract
BACKGROUND Gallstones and cholecystectomy have been proposed as risk factors for non-alcoholic fatty liver disease (NAFLD). The reason for this may be that both gallstones, as well as NAFLD share several risk factors with regards to their development. Currently, there is a lack of sufficient evidence showing an association between these clinical conditions. AIM To determine whether there is a meaningful association between gallstones and cholecystectomy with NAFLD. METHODS We queried the National Inpatient Sample database from the years 2016 and 2017 using International Classification of Diseases, 10th revision, Clinical Modification diagnosis codes to identify hospitalizations with a diagnosis of gallstone disease (GSD) (includes calculus of gallbladder without cholecystitis without obstruction and acquired absence of gallbladder) as well as NAFLD (includes simple fatty liver and non-alcoholic steatohepatitis). Odds ratios (ORs) measuring the association between GSD (includes gallstones and cholecystectomy) and NAFLD were calculated using logistic regression after adjusting for confounding variables. RESULTS Out of 14294784 hospitalizations in 2016-2017, 159259 were found to have NAFLD. The prevalence of NAFLD was 3.3% in patients with GSD and 1% in those without. NAFLD was prevalent in 64.3% of women with GSD as compared to 35.7% of men with GSD. After controlling for various confounders associated with NAFLD and GSD, multivariate-adjusted analysis showed that there was an association between NAFLD with gallstones [OR = 6.32; 95% confidence interval (CI): 6.15-6.48] as well as cholecystectomy (OR = 1.97; 95%CI: 1.93-2.01). The association between NAFLD and gallstones was stronger in men (OR = 6.67; 95%CI: 6.42-6.93) than women (OR = 6.05; 95%CI: 5.83-6.27). The association between NAFLD and cholecystectomy was stronger in women (OR = 2.01; 95%CI: 1.96-2.06) than men (OR = 1.85; 95%CI: 1.79-1.92). P value was less than 0.001 for all comparisons. CONCLUSION NAFLD is more prevalent in women with GSD than men. The association between NAFLD and cholecystectomy/gallstones indicates that they may be risk factors for NAFLD.

Abstract
Background: Venous thromboembolism (VTE) occurs frequently in acute myeloid leukemia (AML) patients. There are no population-based studies from the United States (U.S.) analyzing this association. The study aims to analyze the trends, predictors of mortality, and outcomes of VTE in AML patients.Methods: We analyzed the publicly available Nationwide Inpatient Sample (NIS) for years 2010-2014. Hospitalizations due to AML were identified by previously validated International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes as the primary diagnosis. VTE was identified by ICD-9-CM codes as secondary diagnosis. Hospitalizations with age less than 18 years of age were excluded. The trends and outcomes were determined using Chi-squared (χ2) test and multivariate regression models.Results: From 2010 to 2014, there were 313,282 hospitalizations with a primary diagnosis of AML and 1,633 hospitalizations (0.1%) had VTE as a concurrent diagnosis. There was a significant increase in the proportion of AML hospitalizations with VTE from 0.47% in 2010 to 0.56% in 2014 (P = 0.014). Multivariable regression analysis showed that the odds of in-hospital mortality were not higher in AML hospitalizations with VTE (odds ratio [OR] 1.11; 95% confidence interval [CI] 0.81-1.52; P = 0.5) than those without VTE. Age group above 84 years carried the highest risk of mortality (OR 3.20; 95% CI 2.77-3.70; P < 0.0001) in AML-VTE patients. Black (OR 1.23; 95% CI 1.13-1.35; P < 0.0001) and uninsured patients (OR 1.50; 95% CI 1.31-1.73; P < 0.0001) were at significantly higher odds of in-hospital mortality amongst the AML-VTE hospitalizations.Conclusion: The proportion of AML hospitalizations with VTE continues to rise in the U.S. After adjusting for confounders, increasing age, Black race, and lack of insurance were found to have higher risk of in-hospital mortality in the AML-VTE cohort. The odds of in-hospital mortality in AML hospitalizations with VTE are not higher than those without VTE.

Abstract
Introduction: Paralytic ileus is a common clinical condition leading to significant morbidity and mortality. Most studies to date have focused on postoperative ileus, a common but not exclusive cause of the condition. There are limited epidemiological data regarding the incidence and impact of paralytic ileus and its relationship to other clinical conditions. In this cross-sectional study, we analyzed national inpatient hospitalization trends, demographic variation, cost of care, length of stay, and mortality for paralytic ileus hospitalizations as a whole. Methods: The National Inpatient Sample database was used to identify all hospitalizations with the diagnosis of paralytic ileus (International Classification of Diseases, 9th Revision code 560.1) as primary or secondary diagnosis during the period from 2001 to 2011. Statistical analysis was performed using Cochran–Armitage trend test, Wilcoxon rank sum test, and Poisson regression. Results: In 2001, there were 362,561 hospitalizations with the diagnosis of paralytic ileus as compared to 470,110 in 2011 (p < 0.0001). The age group 65–79 years was most commonly affected by paralytic ileus throughout the study period. In-hospital all-cause mortality decreased from 6.03% in 2001 to 5.10% in 2011 (p < 0.0001). However, the average cost of care per hospitalization increased from US$19,739 in 2001 to US$26,198 in 2011 (adjusted for inflation, p < 0.0001). Conclusion: There was a significant rise in the number of hospitalizations of paralytic ileus with increased cost of care and reduced all-cause mortality.

Abstract
Background Dieulafoy's lesion is a relatively rare, but potentially life-threatening, condition where a tortuous arteriole, most commonly in the stomach, may bleed and lead to significant gastrointestinal hemorrhage. Limited epidemiological data exist on patient characteristics and the annual number of hospitalizations associated with such lesions. The aim of our study is to determine the inpatient burden of Dieulafoy’s lesion. Methods We analyzed the National Inpatient Sample (NIS) database for all subjects with a discharge diagnosis of Dieulafoy's lesion of the stomach, duodenum, and colon using International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes 537.84 and 569.86 as the primary or secondary diagnosis during the period from 2002 to 2011. Statistical significance of variation in the number of hospital discharges and demographics during the study period was achieved using the Cochrane-Armitage trend test. Results In 2002, there were 1,071 admissions with a discharge diagnosis of Dieulafoy's lesion as compared to 7,414 in 2011 (p < 0.0001). Dieulafoy's lesion was found to be most common in the age group of 65-79 years (p < 0.0001). Overall, it was found to be more common in males as compared to females (p = 0.0261). The white race was most commonly affected amongst all the races. The average cost of care per hospitalization increased from $14,992 in 2002 to $25,594 in 2011 (p < 0.0001). Conclusion There has been a steady rise in the number of inpatient admissions with Dieulafoy's lesions. Advances in diagnostic techniques likely play a key role in the higher detection rates along with the possible involvement of other unknown factors. Men, in the age group of 65 to 79 years, and Whites were found to have significantly higher admission rates than all other groups, with a significant increase in the cost of care.

Abstract
BACKGROUND Mupirocin is used specifically for the eradication of nasal meticillin-resistant Staphylococcus aureus (MRSA), but increasing mupirocin resistance restricts its repeated use. The antibacterial effects of manuka honey have been established in vitro; antibacterial activity of other honeys has also been reported. AIM To describe the learning experience from a randomized controlled trial (RCT) comparing the efficacy of medical-grade honey (MGH) with mupirocin 2% for the eradication of nasal MRSA. METHODS Patients colonized in the nose with MRSA and age ≥18 years were recruited. Participants received either one or two courses of MGH or mupirocin 2%, three times per day for five consecutive days. FINDINGS The proportion of patients who were decolonized after one or two courses of treatment was not significantly different between MGH [18/42; 42.8%; 95% confidence interval (CI): 27.7-59.0] and mupirocin 2% (25/44; 56.8%; 95% CI: 41.0-71.7). Non-nasal MRSA colonization was significantly associated with persistent nasal colonization (odds ratio: 5.186; 95% CI: 1.736-5.489; P = 0.003). The rate of new acquisition of mupirocin resistance was 9.75%. CONCLUSION Although not significant, a decolonization rate of 42.8% for MGH was impressive. Our findings suggest that this strategy, which has the potential to combat antimicrobial resistance, should be assessed in similar but larger studies.

Abstract
AIM Imaging for pelvic floor defaecatory dysfunction includes defaecation proctography. Integrated total pelvic floor ultrasound (transvaginal, transperineal, endoanal) may be an alternative. This study assesses ultrasound accuracy for the detection of rectocele, intussusception, enterocele and dyssynergy compared with defaecation proctography, and determines if ultrasound can predict symptoms and findings on proctography. Treatment is examined. METHOD Images of 323 women who underwent integrated total pelvic floor ultrasound and defaecation proctography between 2011 and 2014 were blindly reviewed. The size and grade of rectocele, enterocele, intussusception and dyssynergy were noted on both, using proctography as the gold standard. Barium trapping in a rectocele or a functionally significant enterocele was noted on proctography. Demographics and Obstructive Defaecation Symptom scores were collated. RESULTS The positive predictive value of ultrasound was 73% for rectocele, 79% for intussusception and 91% for enterocele. The negative predictive value for dyssynergy was 99%. Agreement was moderate for rectocele and intussusception, good for enterocele and fair for dyssynergy. The majority of rectoceles that required surgery (59/61) and caused barium trapping (85/89) were detected on ultrasound. A rectocele seen on both transvaginal and transperineal scanning was more likely to require surgery than if seen with only one mode (P = 0.0001). If there was intussusception on ultrasound the patient was more likely to have surgery (P = 0.03). An enterocele visualized on ultrasound was likely to be functionally significant on proctography (P = 0.02). There was, however, no association between findings on imaging and symptoms. CONCLUSION Integrated total pelvic floor ultrasound provides a useful screening tool for women with defaecatory dysfunction such that defaecatory imaging can avoided in some.

Abstract
We report a new measurement of the midrapidity inclusive jet longitudinal double-spin asymmetry, A_{LL}, in polarized pp collisions at center-of-mass energy sqrt[s]=200 GeV. The STAR data place stringent constraints on polarized parton distribution functions extracted at next-to-leading order from global analyses of inclusive deep-inelastic scattering (DIS), semi-inclusive DIS, and RHIC pp data. The measured asymmetries provide evidence at the 3σ level for positive gluon polarization in the Bjorken-x region x>0.05.

Abstract
We present ΛΛ correlation measurements in heavy-ion collisions for Au+Au collisions at sqrt[s_{NN}]=200 GeV using the STAR experiment at the Relativistic Heavy-Ion Collider. The Lednický-Lyuboshitz analytical model has been used to fit the data to obtain a source size, a scattering length and an effective range. Implications of the measurement of the ΛΛ correlation function and interaction parameters for dihyperon searches are discussed.

Abstract
We report the first measurement of charmed-hadron (D(0)) production via the hadronic decay channel (D(0) → K(-) + π(+)) in Au+Au collisions at sqrt[s(NN)] = 200 GeV with the STAR experiment. The charm production cross section per nucleon-nucleon collision at midrapidity scales with the number of binary collisions, N(bin), from p+p to central Au+Au collisions. The D(0) meson yields in central Au + Au collisions are strongly suppressed compared to those in p+p scaled by N(bin), for transverse momenta p(T) > 3 GeV/c, demonstrating significant energy loss of charm quarks in the hot and dense medium. An enhancement at intermediate p(T) is also observed. Model calculations including strong charm-medium interactions and coalescence hadronization describe our measurements.

Abstract
We report the first measurements of the moments--mean (M), variance (σ(2)), skewness (S), and kurtosis (κ)--of the net-charge multiplicity distributions at midrapidity in Au+Au collisions at seven energies, ranging from sqrt[sNN]=7.7 to 200 GeV, as a part of the Beam Energy Scan program at RHIC. The moments are related to the thermodynamic susceptibilities of net charge, and are sensitive to the location of the QCD critical point. We compare the products of the moments, σ(2)/M, Sσ, and κσ(2), with the expectations from Poisson and negative binomial distributions (NBDs). The Sσ values deviate from the Poisson baseline and are close to the NBD baseline, while the κσ(2) values tend to lie between the two. Within the present uncertainties, our data do not show nonmonotonic behavior as a function of collision energy. These measurements provide a valuable tool to extract the freeze-out parameters in heavy-ion collisions by comparing with theoretical models.

Abstract
We report measurements of single- and double-spin asymmetries for W^{±} and Z/γ^{*} boson production in longitudinally polarized p+p collisions at sqrt[s]=510 GeV by the STAR experiment at RHIC. The asymmetries for W^{±} were measured as a function of the decay lepton pseudorapidity, which provides a theoretically clean probe of the proton's polarized quark distributions at the scale of the W mass. The results are compared to theoretical predictions, constrained by polarized deep inelastic scattering measurements, and show a preference for a sizable, positive up antiquark polarization in the range 0.05<x<0.2.

Abstract
Local parity-odd domains are theorized to form inside a quark-gluon plasma which has been produced in high-energy heavy-ion collisions. The local parity-odd domains manifest themselves as charge separation along the magnetic field axis via the chiral magnetic effect. The experimental observation of charge separation has previously been reported for heavy-ion collisions at the top RHIC energies. In this Letter, we present the results of the beam-energy dependence of the charge correlations in Au+Au collisions at midrapidity for center-of-mass energies of 7.7, 11.5, 19.6, 27, 39, and 62.4 GeV from the STAR experiment. After background subtraction, the signal gradually reduces with decreased beam energy and tends to vanish by 7.7 GeV. This implies the dominance of hadronic interactions over partonic ones at lower collision energies.

Abstract
We report the STAR measurements of dielectron (e(+)e(-)) production at midrapidity (|y(ee)|<1) in Au+Au collisions at √[s(NN)]=200 GeV. The measurements are evaluated in different invariant mass regions with a focus on 0.30-0.76 (ρ-like), 0.76-0.80 (ω-like), and 0.98-1.05 (ϕ-like) GeV/c(2). The spectrum in the ω-like and ϕ-like regions can be well described by the hadronic cocktail simulation. In the ρ-like region, however, the vacuum ρ spectral function cannot describe the shape of the dielectron excess. In this range, an enhancement of 1.77±0.11(stat)±0.24(syst)±0.33(cocktail) is determined with respect to the hadronic cocktail simulation that excludes the ρ meson. The excess yield in the ρ-like region increases with the number of collision participants faster than the ω and ϕ yields. Theoretical models with broadened ρ contributions through interactions with constituents in the hot QCD medium provide a consistent description of the dilepton mass spectra for the measurement presented here and the earlier data at the Super Proton Synchrotron energies.

Abstract
Rapidity-odd directed flow (v1) measurements for charged pions, protons, and antiprotons near midrapidity (y=0) are reported in sNN=7.7, 11.5, 19.6, 27, 39, 62.4, and 200 GeV Au+Au collisions as recorded by the STAR detector at the Relativistic Heavy Ion Collider. At intermediate impact parameters, the proton and net-proton slope parameter dv1/dy|y=0 shows a minimum between 11.5 and 19.6 GeV. In addition, the net-proton dv1/dy|y=0 changes sign twice between 7.7 and 39 GeV. The proton and net-proton results qualitatively resemble predictions of a hydrodynamic model with a first-order phase transition from hadronic matter to deconfined matter, and differ from hadronic transport calculations.

Abstract
Azimuthal angular correlations of charged hadrons with respect to the axis of a reconstructed (trigger) jet in Au+Au and p+p collisions at √[s(NN)]=200 GeV in STAR are presented. The trigger jet population in Au+Au collisions is biased toward jets that have not interacted with the medium, allowing easier matching of jet energies between Au+Au and p+p collisions while enhancing medium effects on the recoil jet. The associated hadron yield of the recoil jet is significantly suppressed at high transverse momentum (pTassoc) and enhanced at low pTassoc in 0%-20% central Au+Au collisions compared to p+p collisions, which is indicative of medium-induced parton energy loss in ultrarelativistic heavy-ion collisions.

Abstract
We report the beam energy (sqrt[sNN]=7.7-200 GeV) and collision centrality dependence of the mean (M), standard deviation (σ), skewness (S), and kurtosis (κ) of the net-proton multiplicity distributions in Au+Au collisions. The measurements are carried out by the STAR experiment at midrapidity (|y|<0.5) and within the transverse momentum range 0.4<pT<0.8 GeV/c in the first phase of the Beam Energy Scan program at the Relativistic Heavy Ion Collider. These measurements are important for understanding the quantum chromodynamic phase diagram. The products of the moments, Sσ and κσ2, are sensitive to the correlation length of the hot and dense medium created in the collisions and are related to the ratios of baryon number susceptibilities of corresponding orders. The products of moments are found to have values significantly below the Skellam expectation and close to expectations based on independent proton and antiproton production. The measurements are compared to a transport model calculation to understand the effect of acceptance and baryon number conservation and also to a hadron resonance gas model.

Abstract
The measurement of J/ψ azimuthal anisotropy is presented as a function of transverse momentum for different centralities in Au+Au collisions at sqrt[s(NN)]=200 GeV. The measured J/ψ elliptic flow is consistent with zero within errors for transverse momentum between 2 and 10 GeV/c. Our measurement suggests that J/ψ particles with relatively large transverse momenta are not dominantly produced by coalescence from thermalized charm quarks, when comparing to model calculations.

Abstract
Elliptic flow (v(2)) values for identified particles at midrapidity in Au + Au collisions, measured by the STAR experiment in the beam energy scan at RHIC at sqrt[s(NN)] = 7.7-62.4 GeV, are presented. A beam-energy-dependent difference of the values of v(2) between particles and corresponding antiparticles was observed. The difference increases with decreasing beam energy and is larger for baryons compared to mesons. This implies that, at lower energies, particles and antiparticles are not consistent with the universal number-of-constituent-quark scaling of v(2) that was observed at sqrt[s(NN)] = 200 GeV.

Abstract
STAR's measurements of directed flow (v1) around midrapidity for π±, K±, KS0, p, and p[over ¯] in Au+Au collisions at √[sNN]=200 GeV are presented. A negative v1(y) slope is observed for most of produced particles (π±, K±, KS0, and p[over ¯]). In 5%-30% central collisions, a sizable difference is present between the v1(y) slope of protons and antiprotons, with the former being consistent with zero within errors. The v1 excitation function is presented. Comparisons to model calculations (RQMD, UrQMD, AMPT, QGSM with parton recombination, and a hydrodynamics model with a tilted source) are made. For those models which have calculations of v1 for both pions and protons, none of them can describe v1(y) for pions and protons simultaneously. The hydrodynamics model with a tilted source as currently implemented cannot explain the centrality dependence of the difference between the v1(y) slopes of protons and antiprotons.

Abstract
We report transverse momentum (p(T)≤15 GeV/c) spectra of π(±), K(±), p, p[over ¯], K(S)(0), and ρ(0) at midrapidity in p+p and Au+Au collisions at √S(NN)=200 GeV. Perturbative QCD calculations are consistent with π(±) spectra in p+p collisions but do not reproduce K and p(p[over ¯]) spectra. The observed decreasing antiparticle-to-particle ratios with increasing p(T) provide experimental evidence for varying quark and gluon jet contributions to high-p(T) hadron yields. The relative hadron abundances in Au+Au at p(T)≳8 GeV/c are measured to be similar to the p+p results, despite the expected Casimir effect for parton energy loss.

Abstract
We report new STAR measurements of midrapidity yields for the Λ, Λ[over ¯], K(S)(0), Ξ(-), Ξ[over ¯](+), Ω(-), Ω[over ¯](+) particles in Cu+Cu collisions at √S(NN)==200 GeV, and midrapidity yields for the Λ, Λ[over ¯], K(S)(0) particles in Au+Au at √S(NN)==200 GeV. We show that, at a given number of participating nucleons, the production of strange hadrons is higher in Cu+Cu collisions than in Au+Au collisions at the same center-of-mass energy. We find that aspects of the enhancement factors for all particles can be described by a parametrization based on the fraction of participants that undergo multiple collisions.

Abstract
BACKGROUND The clinical microbiology team observed that patients were not receiving all prescribed doses of vancomycin. Ward staff was confused about ordering and interpreting vancomycin therapeutic drug monitoring (TDM) levels. AIM To audit the incidence of vancomycin dose omission. To implement a series of interventions to improve vancomycin dose administration, and to repeat the audit process to assess these interventions. METHODS Three prospective audits were conducted to assess the impact of vancomycin TDM on administration of vancomycin. After the first audit, a number of changes in the TDM process were undertaken. After review of the second audit, a senior pharmacist coordinated ward-based pharmacists in assisting staff to interpret levels, and TDM interpretative charts were designed for drug charts. Following the third audit, feedback to hospital management and a plan for ongoing education were undertaken. RESULTS There was a significant reduction in the number of vancomycin doses held inappropriately in the third (10% (78/782) of prescribed doses) when compared to the first audit (16% (161/1007) of doses) (p<0.01). Of doses that were held inappropriately, there was a significant decrease in doses held for no apparent reason in audit 3 (16% (27/170) of prescribed doses) when compared to audit 1 (25% (69/282) of doses) (p<0.05). CONCLUSIONS The interventions resulted in a 37.5% reduction in inappropriately held vancomycin doses over a one-year period; 10% of doses are still being held inappropriately. This study highlights the difficulties in identifying barriers to change and changing healthcare worker behaviour.

Abstract
Most patients with faecal incontinence require only a full history (information about other predisposing causes) and examination (assessment for faecal impaction and evaluation of sphincter function and structure). When necessary, anorectal physiological studies, endoanal ultrasound and magnetic resonance imaging allow accurate characterization of sphincter function and structure.

Abstract
BACKGROUND Isovolemic hemodilution has been suggested for blood conservation and to improve hemodynamic tolerance to abdominal aortic cross clamping. However, the hemodynamic effects of hemodilution during descending thoracic aortic cross clamping (DAC) have not been established. We evaluated them in anesthetized swine. METHODS Hemodilution (n = 7) was produced by the isovolemic exchange of blood for 6% hetastarch to a target hematocrit of 20%. Hematocrit in control pigs (n = 7) remained at 30%. DAC was performed at the T9 level for 45 minutes. During a 60-minute reperfusion period, control pigs were infused with lactated Ringer's solution; shed blood was returned to hemodilution pigs, followed by lactated Ringer's. If hypotension occurred despite left atrial pressure of 10 mm Hg or greater, boluses of phenylephrine were given to keep mean arterial pressure above 60 mm Hg. RESULTS Hemodilution caused a marked reduction in hematocrit and in global oxygen delivery (DO2). DAC produced a significant increase in proximal arterial pressure, cardiac index, and DO2 and oxygen consumption (VO2) was markedly reduced in both groups. A significant increase in systemic vascular resistance during DAC occurred only in control pigs. After reperfusion, vascular resistance was significantly lower than baseline in hemodilution pigs, requiring a sixfold greater dose of phenylephrine to avoid hypotension. A lower global DO2 and supply-limited VO2 were also observed in hemodilution pigs. CONCLUSIONS Isovolemic hemodilution maintains hemodynamic stability during DAC. During lower torso reperfusion, however, hemodilution caused hemodynamic instability, decreased global DO2, and limited VO2, which may offset its potential benefits.

Abstract
OBJECTIVE We tested the hypothesis that the pharmacologic properties of a small volume of alpha alpha-cross-linked hemoglobin (alpha alpha Hb) could effectively resuscitate pigs subjected to hemorrhage. METHODS Fourteen pigs hemorrhaged to a mean arterial pressure (MAP) of 40 mm Hg for 60 minutes were treated with a 4-mL/kg 2-minute infusion of 10 g/dL alpha alpha Hb or 7 g/dL human serum albumin, an oncotically matched control solution. RESULTS The removal of blood (17 +/- 1.5 mL/kg) caused the typical physiologic responses to hemorrhagic hypovolemia. Infusion of alpha alpha Hb restored mean arterial pressure and coronary perfusion pressure, but cardiac output and mixed venous O2 saturation did not improve significantly. Pulmonary arterial pressure and pulmonary vascular resistance increased markedly and were higher than baseline levels after alpha alpha Hb. Infusion of human serum albumin produced only minor hemodynamic changes. Brain blood flow did improve to baseline values after alpha alpha Hb, but was the only tissue to do so. In the human serum albumin group, superior mesenteric artery blood flow recovered to baseline values, whereas brain blood flow did not. Blood flows to other tissues were similar in both groups. CONCLUSION Small-volume infusion of alpha alpha Hb restored mean arterial pressure and brain blood flow, but pulmonary hypertension and low peripheral perfusion may offset benefits for trauma patients.
