Cannabis use and cyclical vomiting syndrome: An open debate

INTRODUCTION

Cyclical vomiting syndrome (CVS) carries a significant financial burden on the U.S. healthcare system due to the recurrent emergency department visits and inpatient hospitalizations. We aimed to update the literature on the predictors of hospital utilization and readmission among individuals admitted with CVS.

METHODS

This is a retrospective nationwide study of patients hospitalized with a primary diagnosis of CVS. Using weighted data from the National Inpatient Sample (NIS) and the National Readmission Database (NRD), we conducted a multivariate regression analysis to assess predictors of length of stay (LOS), and 30-day readmission.

RESULTS

Primary admissions for CVS totaled 35,055 in the NIS, and 31,240 in the NRD. 2012 patients (6.4%) were readmitted within 30 days. On multivariate regression, cannabis use was associated with reduced LOS (adjusted Mean Difference (aMD) = -0.53 days, 95% CI: -0.68 to -0.38), and 30-day readmissions (adjusted Hazard Ratio (aHR) = 0.63, 95% CI: 0.54-0.73).

DISCUSSION

Cannabis use among CVS admissions was associated with reduced LOS and 30-day readmissions; these results could be in fact driven by Cannabis Hyperemesis Syndrome (CHS)-related hospitalizations and the effect of cannabis cessation on decreased symptomatology. ICD-10 coding for CHS should be transitioned to specific codes to improve the differentiation between CVS and CHS-related hospitalizations.

Determinants and outcomes of acute pancreatitis in patients hospitalized for COVID-19: Early pandemic experience

OBJECTIVES

To examine the predictors and outcomes associated with the development of acute pancreatitis (AP) in patients hospitalized with Coronavirus Disease 2019 (COVID-19).

METHODS

This is an observational analysis of the 2020 National Inpatient Sample Database. The study includes adult patients who were admitted with a confirmed diagnosis of COVID-19 and stratifies them based on the presence or absence of AP during their hospitalization. Predictors of AP development between the two groups and differences in outcomes are examined. Multivariate logistic regression analysis using Stata/BE 17.0 is conducted, with adjustments made for age, sex, race, and Charlson Comorbidity Index (CCI). Statistical significance is determined at a p-value of <0.05.

RESULTS

Significant factors associated with an increased risk of AP in COVID-19 patients include Hispanic ethnicity, higher Charlson Comorbidity Index (CCI) score, residence in states located in the southern region, history of chronic kidney disease, chronic liver disease, malnutrition, portal hypertension, and alcohol use. COVID-19 patients who developed AP were also found to be at higher risk of adverse outcomes, including mortality, acute coronary syndrome, acute kidney injury, sepsis, septic shock, in-hospital cardiac arrest, invasive mechanical ventilation, upper gastrointestinal bleeding, prolonged length of stay, and increased healthcare cost.

CONCLUSIONS

In hospitalized patients with COVID-19, the presence of AP is associated with increased mortality and morbidity. Risk factors for developing AP in this population include Hispanic ethnicity, residence in the southern region, higher Charlson Comorbidity Index (CCI) score, history of chronic kidney disease, chronic liver disease, malnutrition, portal hypertension, and alcohol use.

Inpatient Outcomes of Gastric Antral Vascular Ectasia in Those With Aortic Stenosis: A Retrospective Study of 85,000 Hospitalizations

GOALS

To investigate the outcomes of hospitalized patients with gastric antral vascular ectasia (GAVE) in the setting of aortic stenosis (AS).

BACKGROUND

Although AS is associated with gastrointestinal arteriovenous malformations, its association with GAVE, a rare cause of upper gastrointestinal bleeding, remains unknown.

STUDY

The National Inpatient Sample database from the years 2016 to 2019 was searched for patients admitted with a diagnosis of GAVE, with and without a history of AS. Univariate and multivariate logistic regression analysis was performed to determine the risk of mortality and in-hospital complications in the GAVE/AS group compared with the GAVE-only group.

RESULTS

Patients with AS had a 2-fold increase in the risk of GAVE [odds ratio (OR): 2.08, P < 0.001], with no statistically significant difference in inpatient mortality between the study groups (OR: 1.36, P = 0.268). Patients with GAVE-AS had a higher risk of hypovolemic shock (OR: 2.00, P = 0.001) and acute coronary syndromes (OR: 2.25, P < 0.001) with no difference in risk of cardiogenic shock (P = 0.695), acute kidney injury (P = 0.550), blood transfusion (P = 0.270), sepsis (P = 0.598), respiratory failure (P = 0.200), or in-hospital cardiac arrest (P = 0.638). The cost of care in patients with GAVE-AS was increased by a mean of $4729 (P = 0.022), with no increase in length of stay (P = 0.320) when compared with patients with GAVE-only.

CONCLUSIONS

Patients with AS have a 2-fold increase in the risk of development of GAVE. Patients with AS admitted for GAVE-related bleeding are at higher rates of hypovolemic shock, acute coronary syndrome, and higher resource utilization when compared with admitted patients with GAVE without AS.

Racial Disparities in Liver Transplantation for Hepatocellular Carcinoma in the United States: An Update

BACKGROUND

Previous studies have demonstrated a disparity in liver transplantation (LT) for hepatocellular carcinoma (HCC) among races in the United States (U.S.).

AIMS

We aimed to update the literature on the odds, trends, and complications of LT in the treatment of hepatocellular carcinoma (HCC), among individuals of different racial backgrounds.

METHODS

This is a nationwide study of adult individuals admitted for LT with a primary diagnosis of HCC. Using weighted data from the National Inpatient Sample (NIS) database, we compared the odds of LT among different races from 2016 to 2020, using a multivariate regression analysis. We further assessed the trends and outcomes of LT among races.

RESULTS

A total of 112,110 adult were hospitalized with a primary diagnosis of HCC. 3020 underwent LT. When compared to Whites, the likelihood of undergoing LT for HCC was significantly reduced in Blacks (OR = 0.60, 95% CI = 0.46-0.78). Further, Blacks had increased mortality rates (7% in Blacks vs. 1% in Whites, p < 0.001), sepsis (11% in Blacks vs. 3% in Whites, p = 0.015), and acute kidney injury (AKI) (54% in Blacks vs. 31% in Whites, p < 0.001) following LT.

CONCLUSIONS

Individuals identifying as Blacks were less likely to undergo LT for HCC, and more likely to develop complications. Further initiatives are warranted to mitigate the existing disparities among racial groups.

The Impact of Inflammatory Bowel Disease on Mortality and Other Outcomes of Hospitalized Patients With Diabetic Ketoacidosis: An Observational Study of the United States National Inpatient Sample

Background

Recent studies have shown an increased risk of diabetes mellitus in patients with Inflammatory bowel disease. However, the impact of IBD on outcomes of patients with diabetic ketoacidosis remains unknown.

Methods

This is an observational analysis of the National Inpatient Sample Database. The authors identified patients with a diagnosis of diabetic ketoacidosis and inflammatory bowel diseases. Outcomes studied were differences in risk of mortality, in-hospital outcomes and healthcare resources utilization. Multivariate logistic analysis was performed and results were adjusted for patient and hospital characteristics and comorbidities.

Results

No significant difference in mortality was observed in the DKA-IBD group when compared to the DKA-only group (aOR 0.55, p = 0.560). Similarly, inflammatory bowel disease had no impact on risk of sepsis (aOR 1.06, p = 0.742), acute kidney injury (aOR 1.08, p = 0.389), acute coronary syndrome (aOR 0.70, p = 0.397), ischemic stroke (aOR 1.53, p = 0.094), acute respiratory failure (aOR 1.00, p = 0.987), invasive mechanical ventilation (aOR 0.54, p = 0.225), deep vein thrombosis (aOR 1.68, p = 0.275), pulmonary embolism (aOR 2.16, p = 0.279) or cardiac arrest (aOR 1.35, p = 0.672) in diabetic ketoacidosis patients. The study group had a significant increase in length of stay (adjusted mean difference 0.63, p = 0.002) and charge of care (adjusted mean difference 3,950$, p = 0.026).

Conclusion

Inflammatory bowel disease is not associated with risk difference in mortality or morbidity in admitted patients with diabetic ketoacidosis, however, it does contribute to increased healthcare resources utilization.

Effect of Hospital Teaching Status on Mortality and Procedural Complications of Percutaneous Paracentesis in the United States: A Four-Year Analysis of the National Inpatient Sample

Objectives

Numerous previous studies investigated the impact of medical training settings on outcomes of hospitalized patients. However, the impact of teaching hospital status on outcomes of percutaneous paracentesis, to the best of our knowledge, has never been studied before.

Methods

Hospitalized patients who underwent percutaneous paracentesis were identified from the National Inpatient Sample database from 2016 to 2019 across the United States (US) teaching and non-teaching hospitals. Outcomes studied were differences in risk of mortality, postprocedural outcomes, and healthcare resource utilization. Multivariate logistic analysis was performed using STATA software (StataCorp LLC, College Station, Texas, US) and results were adjusted for patient and hospital characteristics and comorbidities.

Results

Inpatient mortality rates were significantly higher in patients undergoing paracentesis at US teaching hospitals (adjusted odds ratio (aOR) 1.29, 95%CI 1.23-1.35, p<0.001) compared to non-teaching hospitals. Similarly, higher risk of procedural complications including hemoperitoneum (aOR 1.90, 95%CI 1.65-2.20, p<0.001), hollow viscus perforation (aOR 1.97, 95%CI 1.54-2.51, p<0.001), and vessel injury/laceration (aOR 15.3, 95%CI 2.12-110.2, p=0.007) were noticed in the study group when compared to controls. Furthermore, hospital teaching status was associated with prolonged mean length of stay (9.33 days vs 7.42 days, adjusted mean difference (aMD) 1.81, 95%CI 1.68-1.94, p<0.001) and increased charge of care ($106,014 vs $80,493, aMD $24,926, 95%CI $21,617-$28,235, p <0.001)

Conclusion

Hospitalized patients undergoing paracentesis in US teaching hospitals have an increased risk of mortality, postprocedural complications, prolonged length of stay, and increased charge of care when compared to non-teaching hospitals.

Outcomes of long-term von Willebrand factor prophylaxis use in von Willebrand disease: A systematic literature review

BACKGROUND

Von Willebrand Disease (VWD) is a common inherited bleeding disorder. Patients with VWD suffering from severe bleeding may benefit from the use of secondary long-term prophylaxis.

AIM

Systematically summarize the evidence on the clinical outcomes of secondary long-term prophylaxis in patients with VWD and severe recurrent bleedings.

METHODS

We searched Medline and EMBASE through October 2019 for relevant randomized clinical trials (RCTs) and comparative observational studies (OS) assessing the effects of secondary long-term prophylaxis in patients with VWD. We used Cochrane Risk of Bias (RoB) tool and the RoB for Non-Randomized Studies of interventions (ROBINS-I) tool to assess the quality of the included studies. We conducted random-effects meta-analyses and assessed the certainty of the evidence using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach.

RESULTS

We included 12 studies. Evidence from one placebo controlled RCT suggested that VWD prophylaxis as compared to no prophylaxis reduced the rate of bleeding episodes (Rate ratio [RR], .24; 95% confidence interval [CI], .17-.35; low certainty evidence), and of epistaxis (RR, .38; 95%CI, .21-.67; moderate certainty evidence), and may increase serious adverse events RR 2.73 (95%CI .12-59.57; low certainty). Evidence from four before-and-after studies in which researchers reported comparative data suggested that VWD prophylaxis reduced the rate of bleeding (RR .34; 95%CI, .25-.46; very low certainty evidence).

CONCLUSION

VWD prophylaxis treatment seems to reduce the risk of spontaneous bleeding, epistaxis, and hospitalizations. More RCTs should be conducted to increase the certainty in these benefits.

The Relationship Between Obstructive Sleep Apnea (OSA) and Gastroesophageal Reflux Disease (GERD) in Inpatient Settings: A Nationwide Study

Introduction: Several studies identified a link between gastroesophageal reflux disease (GERD) and obstructive sleep apnea (OSA). GERD is a condition in which acid reflux from the stomach to the esophagus causes troublesome symptoms. On the other hand, OSA is defined as a sleep-related breathing disorder in which airflow significantly decreases or ceases due to upper airway obstruction, leading to arousal from sleep. OSA was found to be associated with GERD. In this study, we aim to study the characteristics and concurrent risk factors associated with GERD and OSA in a large population-based study.

Methods: Patients with the diagnosis of GERD were extracted from the National Inpatient Database (NIS) for the years 2016 to 2019. Patients' age, gender, race, and hospital information, including region and bed size, were extracted and considered as baseline characteristics. The comorbidities included are hypertension (HTN), atrial fibrillation (AFib), congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD), pulmonary hypertension (PHTN), obesity, and smoking. Patients younger than 18 years old were excluded from this study. 

Results: Out of 22,677,620 patients with the diagnosis of GERD, 12.21% had a concurrent diagnosis of OSA (compared to 4.79% in patients without GERD, p-value <0.001). The mean age of patients with GERD and OSA was 64.47 years vs 65.42 years in patients without OSA (p-value <0.001). The GERD and OSA group had almost identical gender distribution compared to the GERD only group, as it was predominantly female patients. The white and black races were slightly more prevalent in the GERD and OSA group compared to the GERD only group. Regarding comorbidities, the prevalence of obesity was more clear in the GERD and OSA group. It was noted that the group of patients who carry a diagnosis of GERD and OSA have more prevalence of diabetes (DM), hypertension (HTN), obesity, atrial fibrillation (Afib), congestive heart failure (CHF), and pulmonary hypertension (PHTN). Patients with GERD and OSA were 21% less likely to be older than 65 years rather than younger (95% CI: 0.79-0.8, p-value <0.001), 35% less likely to be females (95% CI: 0.65-0.65, p-value <0.001), and 22% less likely to be non-white (95% CI: 0.77-0.8, p-value <0.001). Obesity was found to be the strongest association with this population, followed by PHTN, CHF, DM, HTN, Afib, and lastly smoking.

Conclusion: Patients with GERD and OSA were found more likely to be female, white, living in the southern part of the United States, obese, diabetes mellitus type 2, and being active smokers.
