Background/aims Hepatitis B core antibody (HBcAb) positivity of the donor or the recipient may pose a risk of hepatitis B virus (HBV) reactivation following liver transplantation (LT). We retrospectively investigated patient survival and reactivation among recipients who were given low-dose Hepatitis B Immune Globulin (HBIG) plus antiviral agent (AV) versus AV only. Materials and methods Records of cadaveric LT recipients, between 2013 and 2016, with positive Hepatitis B surface Antigen (HBsAg) and/or HBcAb and recipients who had received LT from HBcAb-positive donors were reviewed. Patient characteristics and clinical data were extracted. Donor variables were retrieved from the United Network of Organ Sharing (UNOS) database. HBIG (1560 IU/mL) Intravenous (IV) was intraoperatively administered with three daily doses. Entecavir 1 mg daily was also given. STATA was used for statistical analysis. Results There were 53 recipients; 39 (73.6%) were male with a median age of 59 y. HCV was the major indication in 30 (55.6%) patients. There were 28 recipients (52.8%) who received HBIG plus AV and 25 (47.2%) received AV only. The Model of End Stage Liver Disease (MELD) score between the groups were similar. Survival rates at 6, 12, and 24 months were 100% (n=53), 93.2% (n=44), and 100.0% (n=26), respectively. There was no reactivation; two recipients in the AV group and one in the HBIG plus AV group died within 12 months. Conclusion This study supports the use of low-dose HBIG and AV for post-LT prophylaxis to be as effective as conventionally used high-dose HBIG (9600 IU) plus AV. Future prospective larger studies are warranted to examine the potential benefits of using AV alone without HBIG.

Background and study aims The variables associated with gastroesophageal reflux (GER) after peroral endoscopic myotomy (POEM) are largely unknown. This study aimed to: 1) identify the prevalence of reflux esophagitis and asymptomatic GER in patients who underwent POEM, and 2) evaluate patient and intraprocedural variables associated with post-POEM GER. Patients and methods All patients who underwent POEM and subsequent objective testing for GER (pH study with or without upper gastrointestinal [GI] endoscopy) at seven tertiary academic centers (one Asian, two US, four European) were included. Patients were divided into two groups: 1) DeMeester score ≥ 14.72 (cases) and 2) DeMeester score of Results A total of 282 patients (female 48.2 %, Caucasian 84.8 %; mean body mass index 24.1 kg/m2) were included. Clinical success was achieved in 94.3 % of patients. GER evaluation was completed after a median follow-up of 12 months (interquartile range 10 – 24 months). A DeMeester score of ≥ 14.72 was seen in 57.8 % of patients. Multivariable analysis revealed female sex to be the only independent association (odds ratio 1.69, 95 % confidence interval 1.04 – 2.74) with post-POEM GER. No intraprocedural variables were associated with GER. Upper GI endoscopy was available in 233 patients, 54 (23.2 %) of whom were noted to have reflux esophagitis (majority Los Angeles Grade A or B). GER was asymptomatic in 60.1 %. Conclusion Post-POEM GER was seen in the majority of patients. No intraprocedural variables were identified to allow for potential alteration in procedural technique.

The endogenous cannabinoid system modulates many brain-gut and gut-brain physiologic pathways, which are postulated to be dysfunctional in irritable bowel syndrome (IBS). Herein, we examine the relationship between cannabis use disorder (CUD) and having IBS.After selecting patients aged 18 years and above from the 2014 Nationwide Inpatient Survey, we used the International Classification of Diseases, 9th ed. codes to identify individuals with CUD, IBS, and the established risk factors for IBS. We then estimated the crude and adjusted odds ratios of having a diagnosis of IBS with CUD and assessed for the interactions of CUD with other risk factors (SAS 9.4). We confirmed our findings in two ways: conducting a similar analysis on a previous Nationwide Inpatient Survey data (2012); and using a greedy algorithm to design a propensity-scored case-control (1 : 10) study, approximating a pseudorandomized clinical trial.Out of 4 709 043 patients evaluated, 0.03% had a primary admission for IBS and 1.32% had CUD. CUD was associated with increased odds of IBS [adjusted odds ratio: 2.03; 95% confidence interval (CI): 1.53-2.71]. CUD was related to higher odds for IBS among males compared with females (3.48; 1.98-6.12 vs. 1.48; 0.88-2.50), and Hispanics and Caucasians compared with Blacks (5.28; 1.77-15.76, 1.80; 1.02-3.18 vs. 1.80; 0.65-5.03). On propensity-matching, CUD was associated with 80% increased odds for IBS (1.82; 1.27-2.60).Our findings suggest that CUD is significantly associated with IBS among the general population. Males, Caucasians, and Hispanics might be more impacted by CUD associated IBS. Additional biomedical studies are required to elucidate this relationship.

Tobacco smoking continues to be a bane in the US. Nearly 540, 000 people die annually because of cigarette smoking. These deaths are preventable. Smoking is implicated in lung cancer and many other medical conditions. Billions of dollars have been spent on health issues related to smoking. Lung cancer affects men and women. Nicotine addiction is the culprit in continued smoking and understanding its role is important in promoting smoking cessation. Smoking cessation is important and scientific evidence and approaches exist in the literature. We have explored traditional, non-traditional and novel modalities for smoking cessation and the need for physicians to be actively involved in recommending smoking cessation. We have also discussed special populations that have special requirements for smoking cessation.

Background Self-management support (SMS) for patients with COPD can improve health-related quality of life (HRQOL). However, it remains unclear what SMS strategies are most effective. Using peer support to advance self-management is promising, as peer supporters possess credibility and can serve as role models. Methods We conducted a single-blinded RCT comparing the effectiveness of two strategies to support patients with COPD. The strategies were ‘Health Care Professional (HCP)’ and ‘HCP Plus Peer’ support. Peer support was provided by patients with COPD who have stopped smoking, completed an acute pulmonary rehabilitation program, and met the requirements for becoming a peer supporter. We enrolled patients receiving treatment at inpatient and outpatient settings. Patients were encouraged to invite one family-caregiver to enroll with them. The primary outcome measure was the change in HRQOL at 6 months post enrollment. Secondary outcomes included COPD-related and all-cause hospitalizations and ED visits. Caregiver outcomes included preparedness for caregiving, caregiver stress, and coping. Results A total of 292 patients as well as 50 family-caregivers were enrolled. The average patient age was 67.3 yrs. (SD 9.4), 61% were female and 26% were African-Americans. The majority of caregivers were females (68%) and were a spouse/partner (58%). Discussion This study tested a dual strategy for providing support to patients with COPD that incorporates peer and health care professional support. The study had minimal exclusion criteria. If shown effective, the study offers a program of peer support that can be readily implemented in health care settings.

OBJECTIVES: We aimed to investigate the accuracy of the Milan, University of California San Francisco, and Up-to-7 criteria in predicting tumor recurrence after liver transplant for hepatocellular carcinoma. MATERIALS AND METHODS: For this study, 165 patients with deceased-donor liver transplant for hepatocellular carcinoma were evaluated. The Milan, University of California San Francisco, and Up-to-7 criteria were calculated based on explant pathology. RESULTS: Tumor recurrence rate after liver transplant was 14.6%. Of 165 patients, 115 (70%) were within Milan, 131 (79%) were within University of California San Francisco, and 135 (82%) were within Up-to-7 criteria. The odds ratio of tumor recurrence in patients outside versus within criteria for Milan, University of California San Francisco, and Up-to-7 was 3.6 (95% confidence interval, 1.5–9.1; P = .005), 7.5 (95% confidence interval, 2.5–19.3; P < .001), and 7.5 (95% confidence interval, 2.9–19.6; P < .001) times higher, respectively. The sensitivity of being outside of Milan in predicting tumor recurrence was comparable to University of California San Francisco and Up-to-7 criteria (56.5%, 56.5%, and 52.2%, respectively). Specificity was highest in Up-to-7 (87.3%) versus 85.2% for University of California San Francisco and 73.9% for Milan criteria. The area under the curve for Milan, University of California San Francisco, and Up-to-7 criteria was 0.63, 0.65, and 0.63. CONCLUSIONS: Application of standard criteria has significantly improved prediction of hepatocellular carcinoma recurrence. However, these criteria are inadequate, supporting the importance of other factors, including tumor biology. Research is ongoing in discovering novel biomarkers as predictors of tumor recurrence.

International audience; BACKGROUND:Abusive alcohol use has well-established health risks including causing liver disease (ALD) characterized by alcoholic steatosis (AS), steatohepatitis (AH), fibrosis, cirrhosis (AC) and hepatocellular carcinoma (HCC). Strikingly, a significant number of individuals who abuse alcohol also use Cannabis, which has seen increased legalization globally. While cannabis has demonstrated anti-inflammatory properties, its combined use with alcohol and the development of liver disease remain unclear.AIM:The aim of this study was to determine the effects of cannabis use on the incidence of liver disease in individuals who abuse alcohol.METHODS:We analysed the 2014 Healthcare Cost and Utilization Project-Nationwide Inpatient Sample (NIS) discharge records of patients 18 years and older, who had a past or current history of abusive alcohol use (n = 319 514). Using the International Classification of Disease, Ninth Edition codes, we studied the four distinct phases of progressive ALD with respect to three cannabis exposure groups: non-cannabis users (90.39%), non-dependent cannabis users (8.26%) and dependent cannabis users (1.36%). We accounted for the complex survey sampling methodology and estimated the adjusted odds ratio (AOR) for developing AS, AH, AC and HCC with respect to cannabis use (SAS 9.4).RESULTS:Our study revealed that among alcohol users, individuals who additionally use cannabis (dependent and non-dependent cannabis use) showed significantly lower odds of developing AS, AH, AC and HCC (AOR: 0.55 [0.48-0.64], 0.57 [0.53-0.61], 0.45 [0.43-0.48] and 0.62 [0.51-0.76]). Furthermore, dependent users had significantly lower odds than non-dependent users for developing liver disease.CONCLUSIONS:Our findings suggest that cannabis use is associated with a reduced incidence of liver disease in alcoholics.

Liver fibrosis stage determines risk of morbidity and mortality from chronic hepatitis C virus (HCV) infection. Prior data have shown long-term reversal of liver fibrosis, measured by vibration-controlled transient elastography (VCTE), in patients successfully treated with interferon-based therapies. Our study sought to determine the effect of treatment with modern HCV direct-acting antiviral (DAA) therapy on noninvasive liver fibrosis measurements. A total of 70 patients had VCTE-based liver stiffness measurement (LSM) taken before treatment, directly after treatment completion, and at least 12 months after completion of DAA therapy. Our primary outcome was a >30% improvement in VCTE score at the end of follow-up, relative to baseline. The sustained virologic response rate in our cohort was 95.7%. In our cohort, 34 (48.6%) met the primary outcome. Those who had baseline elevated alanine aminotransferase (OR 3.27; 95% CI 1.13–9.47) and genotype 1 (OR 14.63; 95% CI 1.70–125.83) had higher odds of meeting that outcome, and this remained significant after adjusting for age, baseline body mass index, gender, baseline elevated alkaline phosphatase levels, treatment experience, liver transplant status, smoking, and baseline liver stiffness. Treatment of chronic HCV with modern DAA therapy was associated with a significant improvement in LSM by VCTE measurement, suggesting possible early improvement in liver fibrosis along with resolution of inflammation over the first year after treatment completion.

Background: With increasing legalization of cannabis, there is a growing number of cannabis users in the US. Cannabidiol - a component of cannabis with no psychoactive or cognitive effect has been proven in animal models to have vasodilatory and anti-inflammatory effect on the blood vessels. However, in clinical literature, the association between cerebrovascular accident (CVA) and cannabis remains inconclusive. Objective: To examine if there is a difference in the prevalence of CVA among patients who use cannabis and non-users. Methods: We identified patients > 18 years (N=12,114,360) from the 2012 -2014 National Inpatient Sample database. Using the ICD-9 code, we categorized patients using cannabis (non-dependent and dependent users) and non-users. Our outcome of interest was prevalence of CVA in this population. Logistic regression analysis was performed to assess the association between cannabis use and CVA. Using multivariate regression model, we adjusted for known confounders of CVA; age, gender, race, insurance type, socioeconomic status, tobacco use, cocaine use, alcohol abuse, amphetamine use, hyperlipidemia, diabetes, hypertension, renal failure, prior history of CVA and family history of CVA. Results: From our study sample (12,114,360 hospitalized patients), 2.1% (253,752) had a diagnosis of CVA, 1.48% (179,576) were non-dependent cannabis users and 0.21% (25,968) dependent users. Among hospitalized patient, non-dependent cannabis use was associated with an 8% increased odds of CVA (AOR 1.08 [1.03-1.13]) compared to non-users. However, dependent cannabis use was associated with a 60% decreased odds of CVA (AOR 0.40 [0.31-0.49]) compared to non-users. Also, In-group comparison shows a 60% decreased odds of CVA among dependent cannabis users (AOR 0.36[0.29-0.46]) compared to non-dependent cannabis users. Conclusions: Non-dependent cannabis use was associated with a slightly increased odd of CVA while dependent cannabis use was independently protective against CVA. Our study used the largest repository of clinical information to explore this association, however we recommend more clinical study to explore this correlation in other to maximize the pharmacological benefit of cannabidiol in cannabis for the prevention of CVA.

Introduction: Cannabis is a commonly utilized recreational substance which contains numerous bioactive agents. As more states legalize the use of marijuana, it’s effect on various disease conditions is expected to become more pronounced. Cannabis’ anti-inflammatory effects could suppress pro-inflammatory conditions. For example, chronic inflammation with extracellular matrix degradation resulting in weakness and abnormal dilatation of the aortic wall is a hallmark of Aortic Aneurysm. We, therefore, hypothesized that cannabis users would have less prevalence of aortic aneurysms. Objective: To identify the relationship between chronic cannabis use (CU) and diagnosis of aortic aneurysms (AA) among hospitalized patients. Methods: After selecting patients who were 55 years and above from 2012 to 2014 National Inpatient Sample database, we identified those who had a diagnosis of Aortic Aneurysm and those who utilize Cannabis. We then stratified the CU into two groups: nondependent (NDU) and dependent users (DU). Using logistic regression, we estimated the Odds Ratio (AOR) after controlling for numerous factors. Results: In our total 10,461,694 sample, 99.6% (10,419,972) are non-users, 0.37% (38,514) are nondependent users and 0.03% (3,208) are dependent users. About 3.21% (336,202) of the patients had a diagnosis of AA versus 96.79% (10,125,492) without a diagnosis of AA. Compared to non-users of cannabis, the odds of AA is about 35% less among CU (AOR 0.66[0.62-0.71]), 40% less among DU (aOR 0.58[0.44-0.76]), and 33% less among NDU (AOR 0.67[0.62-0.72]). The odds of AA was lower in females (AOR 0.61[0.60-0.610]), but higher in many conditions such as: among >=65 years (AOR 1.16[1.15-1.17]), tobacco users (AOR 1.18[1.17-1.19]), predisposing hereditary conditions (AOR 5.31[4.60-6.13]), and atherosclerosis (AOR 3.04[3.00-3.08]). Conclusions: Our result shows that Cannabis use is associated with less occurrence of AA. Cannabidiol, an anti-inflammatory alkaloid in Cannabis could potentially suppress the release of proteolytic inflammatory mediators which might be responsible for the gradual weakening of the vascular walls. We recommend more basic research to evaluate this effect of Cannabidiol.

Background: Although, in-hospital mortality from acute myocardial infarction (AMI) have declined in the United States recently, there is a gap in knowledge regarding racial differences in this trend. We sought to evaluate the effect of race on the trends in outcomes after Acute Myocardial Infarction among Medicaid patients in a nationwide cohort from 2007-2011 Methods: We extracted data from the Nationwide Inpatient Sample (NIS) for all hospitalizations between 2007 and 2011 for Medicaid patients aged 45 years or older with principal diagnosis of AMI using ICD-9-CM codes. Primary outcome of this study was all cause in-hospital mortality. We then stratified hospitalizations by racial groups; Whites, African Americans and Hispanics, and assessed the time trends of in-hospital mortality before and after multivariate analysis. Results: The overall mortality from AMI among Medicaid patients declined during the study period (8.80% in 2007 to 7.46% in 2011). In the adjusted models, compared to 2007, in-hospital mortality from AMI for Medicaid patients decreased across the 3 racial groups; Whites (aOR= 0.88, CI=0.70-0.99), African Americans (aOR=0.76, CI=0.57-1.01), Hispanics (aOR=0.87, CI=0.66-1.25). While the length of hospital stay declined significantly among African American and Hispanic with 2 days and 1.76 days decline respectively, the length of stay remained unchanged for Whites. There was non-significant increase in the incidence of stroke across the various racial groups; Whites (aOR= 1.23, CI=0.90 -1.69), African Americans (aOR=1.10, CI=0.73 -1.64), Hispanics (aOR=1.03, CI=0.68-1.55) when compared to 2007. Conclusion: In this study, we found that in-hospital mortality from AMI among Medicaid patients have declined across the racial groups. However, while the length of stay following AMI declined for African Americans and Hispanics with Medicaid insurance, it has remained unchanged for Whites. Future studies are necessary to identify determinants of these significant racial disparities in outcomes for AMI.

Background: Despite being illegal in most countries, cannabis is highly utilised by a growing number of individuals for recreational purposes worldwide. With its increasing legalisation in many states across the United States, the effects of cannabis on different body systems are expected to rise. Its association with peripheral vascular disease (PVD) remains ambiguous. Objective: To examine if there is a difference in prevalence of PVD amongst patients who use cannabis when compared to non-users. Methods: Using the 2014 National Inpatient Sample database (N=7,071,762), we identified patients with and without a diagnosis of PVD. We also identified patients using cannabis (nondependent and dependent users) and non-users. We performed the univariate and bivariate analysis. After we had composed the crude models, we adjusted for every known risk factor for PVD. These factors included age, gender, tobacco, hypercholesterolemia, coronary artery disease (CAD), cerebrovascular vessel disease (CVD), hypertension, diabetes, renal failure, alcohol, obesity, race, insurance type, average income at the location of residence, and family history of PVD/CVD/CAD. Results: In our total 7,071,762 sample, 98.27% (6,949,339) are non-users, 1.54% (108,910) are nondependent users and 0.19% (13,513) are dependent users. About 3.75% (264,920) of the patients had a diagnosis of PVD versus 96.25% (6,806,842) without a diagnosis of PVD. The odds of PVD is 20% less among nondependent users when compared to nonusers (AOR 0.80[0.76-0.85]). Furthermore, dependent users have a 55% reduced odds of developing PVD when compared to nonusers (AOR 0.45[0.35-0.57]) showing a dose-response relationship. The in-group comparison showed that dependent users were 44% less likely to have PVD when compared to non-dependent users (AOR: 0.56[0.44-0.72]). Overall, the odds of PVD remain significantly high among patients who uses tobacco (AOR 1.97 [1.95-1.99]), diabetes (AOR 1.54 [1.53-1.55]), hypercholesterolemia (AOR 1.46 [1.45-1.47]), family history of PVD/CVD/CAD (AOR 1.03 [1.01-1.05]), personal history of CAD (AOR 2.55 [2.53-2.57]). Conclusions: Cannabis is an independent protective factor against PVD. Molecular biology evidence shows that cannabis contains various bioactive agents. Beta-caryophyllene (out of many) preferentially binds to CB-2 receptors on immune cells causing an anti-inflammatory response. We believe that more molecular studies targeting such receptors or isolating such anti-inflammatory compounds in cannabis might be useful in the treatment of vascular disease.

Background: Diabetes has been associated with complications and poor perioperative outcomes. In Radiofrequency catheter ablation - therapy of choice for drug refractory atrial fibrillation and flutter, association between diabetes and procedural complications are less documented. Objectives: To examine if there is a difference in perioperative complications in patients with chronic diabetes who underwent RFA for atrial fibrillation/flutter when compared with non-diabetics. Methods: We selected patients > 45 years from the National Inpatient Survey data 2014. We identified 8356 patients (69.6 ± 9.1yrs) who underwent catheter ablation. Logistic regression analyses were performed to investigate the difference in perioperative complications (hemorrhage, cardiac perforation, cardiac complications, respiratory complications, peripheral vascular complications, stroke and in-hospital mortality) between diabetics and non-diabetics. All models were adjusted for age, gender, race, residential income, insurance, co-morbidities, hospital bed size, hospital location/teaching status, hospital region, length of stay and median household income. Results: Among our selected 8356 patients, 5777(69.1%) were non-diabetics, 2203(26.4%) had uncomplicated diabetes and 376 (4.5%) complicated diabetes. Overall there were 634 events (240 hemorrhages, 56 perforations, 163 cardiac complications, 43 respiratory complications, 12 strokes, 40 peripheral vascular complications and 80 in-hospital death. Rates of complications were the same among diabetes and non-diabetics. In the multivariate models, the odds of complications remain statistically non-significant across all the groups. However, among all the patients who underwent RFA, there is an increased odds of hemorrhage among patients with Medicare insurance versus private insurance (OR 1.73 95%CI 1.11-2.70), peripheral vascular complications among hospitals in the south (OR 3.35 95%CI 1.30-9.62), respiratory complications among patients with CHF (4.60 95%CI 1.68-12.60), death among patients with renal failure (OR 2.22 95%CI 1.32-3.73) and hospitals in the south (2.55 95% CI 1.08-6.0) and west (OR 3.23 95%CI 1.25-8.3) compared to the northeast. Odds of stroke were less among both urban non-teaching (OR 0.02 95%CI 0.01 - 0.34) and teaching hospital (OR 0.05 95%CI 0.01-0.36) when compared to rural hospital. Conclusions: RFA has a similar procedural safety in diabetics when compared to non-diabetic patients. It remains a safe procedure in diabetics with drug-refractory atrial fibrillation and flutter. Renal failure, CHF, type of Insurance, hospital location and teaching status are predictors of complications after RFA.

International audience; Cannabis use is associated with reduced prevalence of obesity and diabetes mellitus (DM) in humans and mouse disease models. Obesity and DM are a well-established independent risk factor for non-alcoholic fatty liver disease (NAFLD), the most prevalent liver disease globally. The effects of cannabis use on NAFLD prevalence in humans remains ill-defined. Our objective is to determine the relationship between cannabis use and the prevalence of NAFLD in humans. We conducted a population-based case-control study of 5,950,391 patients using the 2014 Healthcare Cost and Utilization Project (HCUP), Nationwide Inpatient Survey (NIS) discharge records of patients 18 years and older. After identifying patients with NAFLD (1% of all patients), we next identified three exposure groups: non-cannabis users (98.04%), non-dependent cannabis users (1.74%), and dependent cannabis users (0.22%). We adjusted for potential demographics and patient related confounders and used multivariate logistic regression (SAS 9.4) to determine the odds of developing NAFLD with respects to cannabis use. Our findings revealed that cannabis users (dependent and non-dependent) showed significantly lower NAFLD prevalence compared to non-users (AOR: 0.82[0.76-0.88]; p

A 62 year old female on omeprazole with a history of hiatal hernia, gastroesophageal reflux disease (GERD), and esophagitis presented with acute onset of nausea and vomiting. She vomited approximately 20 times, quantified as half a cup mixed with dark red blood. Initially, the emesis was all recently ingested meals. The emesis became bloody after 24 hours of vomiting, leading to her presentation in the ER. She continued to feel nauseous with belching in the ER. She denied any abdominal pain, diarrhea, constipation, chest pain, odynophagia or shortness of breath. She had no melena, hematochezia, fevers, chills or weight loss. She denied any NSAID use or recent international travel. She had no family history of gastrointestinal malignancy and no history of tobacco use. Her physical examination and vital signs were unremarkable. Laboratory data was significant for white cell count of 18.78 K/µL, hemoglobin of 15.7 G/DL, hematocrit 46.3% (hemoglobin & hematocrit at baseline), mean corpuscular volume 88FL, platelet count 65 K/µL and INR was 1.0. Her chemistry, liver function test, lipase and amylase were within normal limits. Computed tomography(CT) scan of the chest was done.

OBJECTIVES/SPECIFIC AIMS: To assess the effect of cannabis on impaired judgment and health outcomes among heart failure patients in the emergency room. METHODS/STUDY POPULATION: Patients with heart failure presenting to the emergency room. Cannabis with confounders such as income level, insurance type, tobacco use, and age. Discharged against medical advice to assess impaired judgment. Hospitalization rates, length of stay, and death rate to assess health outcomes. Multivariate logistic regression to access the odds of each of these outcomes from cannabis RESULTS/ANTICIPATED RESULTS: Cannabis is associated with impaired outcome (increase in discharge against medical advice). Cannabis have poorer health outcome in terms of more hospitalizations from the emergency department. Cannabis also have better health outcome in terms of shorter length of stay and death rate among cannabis users Versus nonusers. DISCUSSION/SIGNIFICANCE OF IMPACT: This is crucial to inform health care providers to ensure better counseling of cannabis users. This result should also be considered to interpret other publications that shows better outcomes in patients taking cannabis. Cannabis users might only seem to have a better outcome because they tend to discharge against medical advice and thereby die outside the hospital, etc.

Thank you for your comment[1][1] on our article.[2][2] Based on the Infectious Diseases Society of America’s (IDSA’s) 2010 guideline[3][3] on when to treat asymptomatic bacteriuria, I disagree with your statement and stand by our publication. “Pyuria accompanying CA-ASB [asymptomatic

Even though Streptococcus bacteraemia is an infrequent presentation of colonic malignancies, there is a well-established link between Streptococcus bovis bacteraemia and colonic malignancies. Most of the physicians are well aware of this correlation and further workup is pursued in most of the cases. However, many physicians may not be aware that other species of Streptococcus viridians, other than S. bovis, can be associated with colonic malignancies. In this case report, we present a case of Streptococcus viridians (anginosus) bacteraemia as a complication of an undiagnosed sigmoid adenocarcinoma. While further evidence is needed to warrant a gastrointestinal (GI) workup in a patient with other species of Streptococcus viridians bacteraemia, we would like to increase the awareness in the physicians’ community regarding Streptococcus viridians, other than S. bovis bacteraemia. This would be especially relevant for patients who have no GI screening, as Streptococcus viridians bacteraemia can be an early sign of colonic neoplasm.

Malignant mesothelioma is an uncommon neoplasm of serosal surfaces, such as the pleura, the peritoneum, less frequently pericardium and tunica vaginalis. It usually spreads locally to the lungs and mediastinum. We describe a case of malignant mesothelioma with metastasis to the heart. The patient presented with syncope, chest pain and light-headedness. He was found to have wide complex ventricular tachycardia (Vtach). He was cardioverted and then noted to have multiple (more than 20) similar episodes during the hospital course. He was treated with multiple antiarrhythmic medications. A CT scan of the chest revealed a circumferential rind of soft tissue in the right hemithorax and invasion of the pericardium. The repeated Vtach episodes were secondary to the metastasis of the pericardium. Oncology was involved and as there were no further treatment options available, the patient was discharged home with hospice care. The disease is a huge economic burden and early recognition can lead to better outcomes.

Single nucleotide polymorphisms (SNPs) in the epidermal growth factor (EGF, rs4444903), patatin-like phospholipase domain-containing protein 3 (PNPLA3, rs738409) genes, and near the interleukin-28B (IL28B, rs12979860) gene are linked to treatment response, fibrosis, and hepatocellular carcinoma (HCC) in chronic hepatitis C. Whether these SNPs independently or in combination predict clinical deterioration in hepatitis C virus (HCV)-related cirrhosis is unknown. We genotyped SNPs in EGF, PNPLA3, and IL28B from liver tissue from 169 patients with biopsy-proven HCV cirrhosis. We estimated risk of clinical deterioration, defined as development of ascites, encephalopathy, variceal hemorrhage, HCC, or liver-related death using Cox proportional hazards modeling. During a median follow-up of 6.6 years, 66 of 169 patients experienced clinical deterioration. EGF non-AA, PNPLA3 non-CC, and IL28B non-CC genotypes were each associated with increased risk of clinical deterioration in age, sex, and race-adjusted analysis. Only EGF non-AA genotype was independently associated with increased risk of clinical deterioration (hazard ratio [HR] 2.87; 95% confidence interval [CI] 1.31–6.25) after additionally adjusting for bilirubin, albumin, and platelets. Compared to subjects who had 0–1 unfavorable genotypes, the HR for clinical deterioration was 1.79 (95%CI 0.96–3.35) for 2 unfavorable genotypes and 4.03 (95%CI 2.13–7.62) for unfavorable genotypes for all three loci (Ptrend

A 51-year-old male with a history of depression and multiple prior suicide attempts was found obtunded in his car, along with a half-full bottle of industrial-strength drain cleaner. His exam was notable only for altered sensorium. Laboratory data showed potassium of 5.6 mEq/L, lactate 2.5 mmol/L andWBC 13.1 k/uLHis urinewas positive for benzodiazepine and oxycodone. Abdominal x-ray demonstrated gastric wall thickening and extensive small bowel gas without evidence of free air (Fig. 1). EGD showed severe esophageal ulceration with necroticappearing mucosa and ulcerated, friable gastric mucosa without evidence of perforation—findings which were consistent with a grade 3 esophageal caustic injury from alkali intake (Fig. 2). He was started on intravenous pantoprazole infusion and total parenteral nutrition (TPN). He remained on TPN for one month. Caustic alkali injuries represent direct trauma to the mucosal tissue from a process known as liquefactive necrosis, which may ultimately lead to perforation, rupture, or even death. Given the severity of potential short-term complications, patients with suspected injury should undergo urgent endoscopy within 24 h and be closely followed thereafter. Long-term complications of esophageal caustic injuries include esophageal strictures and 1000-fold increased risk of esophageal squamous cell cancer.

A 58-year-old woman presented with intermittent, nonexertional chest pain. She had been admitted for similar symptoms 2 months earlier; a coronary angiogram had revealed normal anatomy. A transthoracic echocardiogram revealed a pericardial effusion. A video is available at NEJM.org.

Hypersensitivity reactions during haemodialysis are well documented in the literature. Most dialysis membrane reactions occur with ethylene oxide or non-biocompatible membranes and less frequently with biocompatible membranes. The symptoms are non-specific except for the temporal relationship typically occurring during the haemodialysis. Patients who present with the non-classic type of reaction pose a diagnostic challenge and clinicians must have a high index of suspicion. We present a non-classic presentation of a hypersensitivity reaction to a polysulfone membrane dialyser with recurrent fevers during and after haemodialysis, initially thought to be due to infection. After a series of negative work ups for infection, dialysis membrane reaction was considered and the patient improved after change of the membrane.

We describe the case of a healthy 23-year-old man who presented to the emergency room with a 10 h history of sharp left lower chest pain occasionally radiating to the epigastrium. The pain had started acutely while he was eating dinner at a restaurant in New York City and he noticed it during swallowing. The pain was initially sharp but later became dull. There were intermittent episodes of sharp pain, exacerbated by deep inspiration and swallowing. Lying on his right side alleviated the pain. He reported no fevers, cough, nausea or vomiting. Initial evaluation including electrocardiogram, chest …

West Nile virus (WNV) is still the most common cause of neuroinvasive arboviral disease in the USA with a case death of 10–30%. We are reporting a case of a 61-year-old woman with a history of Crohn's disease, fibromyalgia treated with chronic steroid therapy that presented with a day history of fever, confusion and lethargy. She had a lumbar puncture which was notable for lymphocytosis and was positive for WNV. She initially was treated with broad-spectrum antibiotics, which were subsequently discontinued when the diagnosis of WNV neuroinvasive disease (WNND) was made. A high index of suspicion is needed to diagnose WNND, and this should be suspected in elderly immunocompromised patient presenting with altered mental status and lumbar puncture suggestive of aseptic meningitis. Recent study has showed that there is genetic variation in the interferon response pathway which is associated with both risk for symptomatic WNV infection and disease progression.
