Hemospray® (hemostatic powder TC-325) as monotherapy for acute gastrointestinal bleeding: a multicenter prospective study.

Background: Hemostatic powders are used as second-line treatment in acute gastrointestinal (GI) bleeding (AGIB). Increasing evidence supports the use of TC-325 as monotherapy in specific scenarios. This prospective, multicenter study evaluated the performance of TC-325 as monotherapy for AGIB. Methods: Eighteen centers across Europe and USA contributed to a registry between 2016 and 2022. Adults with AGIB were eligible, unless TC-325 was part of combined hemostasis. The primary endpoint was immediate hemostasis. Secondary outcomes were rebleeding and mortality. Associations with risk factors were investigated (statistical significance at P≤0.05). Results: One hundred ninety patients were included (age 51-81 years, male: female 2:1), with peptic ulcer (n=48), upper GI malignancy (n=79), post-endoscopic treatment hemorrhage (n=37), and lower GI lesions (n=26). The primary outcome was recorded in 96.3% (95% confidence interval [CI]: 92.6-98.5) with rebleeding in 17.4% (95%CI 11.9-24.1); 9.9% (95%CI 5.8-15.6) died within 7 days, and 21.7% (95%CI 15.6-28.9) within 30 days. Regarding peptic ulcer, immediate hemostasis was achieved in 88% (95%CI 75-95), while 26% (95%CI 13-43) rebled. Higher ASA score was associated with mortality (OR 23.5, 95%CI 1.60-345; P=0.02). Immediate hemostasis was achieved in 100% of cases with malignancy and post-intervention bleeding, with rebleeding in 17% and 3.1%, respectively. Twenty-six patients received TC-325 for lower GI bleeding, and in all but one the primary outcome was achieved. Conclusions: TC-325 monotherapy is safe and effective, especially in malignancy or post-endoscopic intervention bleeding. In patients with peptic ulcer, it could be helpful when the primary treatment is unfeasible, as bridge to definite therapy.

Successes and challenges of best practice alerts to identify and engage individuals living with hepatitis C virus.

Introduction: Many individuals living with hepatitis C virus (HCV) are unaware of their diagnosis and/or have not been linked to programs providing HCV care. The use of electronic medical record (EMR) systems may assist with HCV infection identification and linkage to care. Methods: In October 2021, we implemented HCV serology-focused best practice alerts (BPAs) at The Ottawa Hospital (TOH) via our EMR (EPIC). Our BPAs were programmed to identify previously tested HCV seropositive individuals. Physicians were prompted to conduct HCV RNA testing and submit consultation requests to the TOH Viral Hepatitis Program. We evaluated data post-BPA implementation to assess the design and related outcomes. Results: From 1 September 2022 to 15 December 2022, a total of 2,029 BPAs were triggered for 139 individuals. As a consequence of the BPA prompts, nine HCV seropositive and nine HCV RNA-positive individuals were linked to care. The proportion of total consultations coming from TOH physicians increased post-BPA implementation. The BPA alerts were frequently declined, and physician engagement with our BPAs varied across specialty groups. Programming issues led to unnecessary BPA prompts (e.g., no hard stop to the prompts even though the individual was treated and cured and individuals linked to care without first undergoing HCV RNA testing). A fixed 6-month lookback period for test results limited our ability to identify many individuals. Conclusion: An EMR-based BPA can assist with the identification and engagement of HCV-infected individuals in care. However, challenges including issues with programming, time commitment toward BPA configuration, productive communication between healthcare providers and the programming team, and physician responsiveness to the BPAs require attention to optimize the impact of BPAs.

Utilization of Anti-obesity Medications After Bariatric Surgery: Analysis of a Large National Database.

PURPOSE: A significant proportion of patients experience insufficient weight loss or weight regain after bariatric surgery. There is a paucity of literature describing anti-obesity medication (AOM) use following bariatric surgery. We sought to identify prevalence and trends of AOM use following bariatric surgery. MATERIALS AND METHODS: We utilized the IBM Explorys® database to identify all adults with prior bariatric surgery (Roux-en-Y gastric bypass or sleeve gastrectomy). Those prescribed AOMs (semaglutide, liraglutide, topiramate, phentermine/topiramate, naltrexone/bupropion, orlistat) within 5 years of surgery were further identified. Data was analyzed to characterize AOM utilization among different age, demographic, and comorbid populations. RESULTS: A total of 59,160 adults with prior bariatric surgery were included. Among AOMs studies, prevalence of use was highest for topiramate (8%), followed by liraglutide (2.9%), phentermine/topiramate (1.03%), naltrexone/bupropion (0.95%) semaglutide (0.52%), and orlistat (0.17%). Age distribution varied, with the highest utilization among those age 35-39 years for topiramate, 40-44 years for phentermine/topiramate and naltrexone/bupropion, 45-49 years for semaglutide, and 65-69 years for liraglutide and orlistat. African American race was associated with higher utilization across all AOMs. Among comorbidities, hypertension, hyperlipidemia, and diabetes mellitus were most associated with AOM use. CONCLUSION: Despite a relatively high incidence of weight regain, AOMs are underutilized following bariatric surgery. It is imperative that barriers to their use be addressed and that AOMs be considered earlier and more frequently in patients with insufficient weight loss or weight regain after bariatric surgery.

Association of Bariatric Surgery with Risk of Incident Obesity-Associated Malignancies: a Multi-center Population-Based Study.

INTRODUCTION: Obesity has a known association with certain types of malignancy, and we aimed to determine whether bariatric surgery has a protective effect against de novo obesity-associated cancer development in adult patients. METHODS: We performed a multi-center retrospective cohort studying utilizing TriNetX national database. Patients were identified utilizing ICD-10-CM coding, and propensity score matching was performed. We compared patients with obesity who underwent bariatric surgery to patients with obesity who did not undergo bariatric surgery. RESULTS: We initially identified 60,285 patients in the bariatric surgery group and 1,570,440 patients in nonsurgical control group. After propensity score matching, we included 55,789 patients in each patient cohort. The cumulative incidence of de novo obesity-associated cancers at 10 years was 4.0% (2206 patients) in the bariatric surgery group and 8.9% (4,960 patients) in the nonsurgical control group (HR 0.482 [95% CI 0.459-0.507]). The bariatric surgery group had lower incidence proportions for de novo breast cancer (HR 0.753 [CI 0.678-0.836]), colon cancer (HR 0.638 [CI 0.541-0.752]), liver cancer (HR 0.370 [CI 0.345-0.396]), ovarian cancer (HR 0.654 [CI 0.531-0.806]), and endometrial cancer (HR 0.448 [CI 0.362-0.556]) when compared to the nonsurgical control group. CONCLUSION: We noted that bariatric surgery is associated with a significantly lower cumulative incidence of de novo obesity-associated cancer compared to a nonsurgical matched control group. Incidence proportions of de novo breast, colon, liver, ovarian, and endometrial cancer were significantly lower in adult patients with obesity in the bariatric surgery group compared to the nonsurgical group.

Intracystic Glucose and Carcinoembryonic Antigen in Differentiating Histologically Confirmed Pancreatic Mucinous Neoplastic Cysts.

INTRODUCTION: Differentiating mucinous neoplastic pancreatic cysts (MNPC) from cysts without malignant potential can be challenging. Guidelines recommend using fluid carcinoembryonic antigen (CEA) to differentiate MNPC; however, its sensitivity and specificity vary widely. Intracystic glucose concentration has shown promise in differentiating MNPC, but data are limited to frozen specimens and cohorts of patients without histologic diagnoses. This study aimed to compare glucose and CEA concentrations in differentiating MNPC using fresh fluid obtained from cysts with confirmatory histologic diagnoses. METHODS: This multicenter cohort study consisted of patients undergoing endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) for pancreatic cysts during January 2013-May 2020. Patients were included if the cyst exhibited a histologic diagnosis and if both CEA and glucose were analyzed from fresh fluid. Receiver operating curve (ROC) characteristics were analyzed, and various diagnostic parameters were compared. RESULTS: Ninety-three patients, of whom 59 presented with MNPC, met the eligibility criteria. The area under the receiver operating curve (AUROC) was 0.96 for glucose and 0.81 for CEA (difference 0.145, P = 0.003). A CEA concentration of ≥192 ng/mL had sensitivity of 62.7% and specificity of 88.2% in differentiating MNPC, whereas glucose concentration of ≤25 mg/dL had sensitivity and specificity of 88.1% and 91.2%, respectively. DISCUSSION: Intracystic glucose is superior to CEA concentration for differentiating MNPC when analyzed from freshly obtained fluid of cysts with histologic diagnoses. The advantage of glucose is augmented by its low cost and ease of implementation, and therefore, its widespread adoption should come without barriers. Glucose has supplanted CEA as the best fluid biomarker in differentiating MNPC.

90-Day Specific Readmission for Clostridium difficile Infection After Hospitalization With an Inflammatory Bowel Disease Flare: Outcomes and Risk Factors.

BACKGROUND: Patients with inflammatory bowel disease (IBD) have an increased risk for Clostridium difficile infection (CDI) and carry significantly higher morbidities and mortality than those without IBD. We aimed to investigate disease-specific readmission rates and independent risk factors for CDI within 90 days of an index hospitalization for an IBD flare. METHODS: The Nationwide Readmission Database was queried for the year 2016. We collected data on hospital readmissions of 50,799 adults who were hospitalized for urgent IBD flare and discharged. The primary outcome was disease-specific readmission rate for CDI within 90 days of discharge. The secondary outcomes were readmission rate of colonoscopic procedures, morbidities (including mechanical ventilation and shock), and hospital economic burden. The risk factors for readmission were identified using Cox regression analysis. RESULTS: The 90-day specific readmission rate was 0.1% (N = 477). A total of 3,005 days were associated with readmission, and the total health care in-hospital economic burden of readmission was $19.1 million (in charges) and $4.79 million (in costs). Independent predictors during index admission for readmission were mechanical ventilation for >24 hours (hazard ratio [HR], 6.62, 95% confidence interval [CI], 0.80-54.57); history of previous CDI (HR, 5.48; 95% CI, 3.66-8.19); HIV-positive status (HR, 4.60; 95% CI, 1.03-20.50); alcohol abuse disorders (HR, 2.06; 95% CI, 1.15-3.70); Parkinson's disease (HR, 4.68; 95% CI, 1.65-13.31); index admission for noncomplicated ulcerative colitis (HR, 4.72; 95% CI, 2.99-7.45]-), complicated ulcerative colitis (HR, 4.49; 95% CI, 2.80- 7.18), or noncomplicated Crohn disease (HR, 2.54; 95% CI, 2.80-4.04); and hospital length of stay (HR, 1.01; 95% CI, 1.01-1.02). CONCLUSIONS: The 90-day CDI-specific readmission rate after the index admission of IBD flares was 0.1%. We found risk factors for CDI-associated readmissions such as history of Parkinson's disease, prior CDI, HIV-positive status, and alcohol abuse disorder. Finally, our study also revealed a high health care cost, charges, and burden.

Association Between Cannabis Use and Complications Related to Crohn's Disease: A Retrospective Cohort Study.

BACKGROUND: Crohn's disease is an idiopathic inflammatory process that is occasionally associated with complications, which cause significant morbidity and mortality. The anti-inflammatory effect of cannabis in intestinal inflammation has been shown in several experimental models; it is unknown whether this correlates with fewer complications in Crohn's disease patients. AIMS: To compare the prevalence of Crohn's disease-related complications among cannabis users and non-users in patients admitted with a primary diagnosis of Crohn's disease or a primary diagnosis of Crohn's related complication and a secondary diagnosis of Crohn's disease between 2012 and 2014. METHODS: We used data from the Healthcare Cost and Utilization Project-National Inpatient Sample. Cannabis users (615) were compared directly after propensity score match to non-users, in aspects of various complications and clinical end-points. RESULTS: Among matched cohorts, Cannabis users were less likely to have the following: active fistulizing disease and intra-abdominal abscess (11.5% vs. 15.9%; aOR 0.68 [0.49 to 0.94], p = 0.025), blood product transfusion (5.0% vs. 8.0%; aOR 0.48 [0.30 to 0.79], p = 0.037), colectomy (3.7% vs. 7.5%; aOR 0.48 [0.29-0.80], p = 0.004), and parenteral nutrition requirement (3.4% vs. 6.7%, aOR 0.39 [0.23 to 0.68], p = 0.009). CONCLUSION: Cannabis use may mitigate several of the well-described complications of Crohn's disease among hospital inpatients. These effects could possibly be through the effect of cannabis in the endocannabinoid system.

Personnel training and patient education in medical marijuana dispensaries in Oregon.

OBJECTIVES: To determine the knowledge and training of Oregon Medical Marijuana Dispensary (OMMD) personnel and describe the information and type of advice provided to patients who use Oregon dispensaries. METHODS: Statewide cross-sectional email survey of OMMD personnel. RESULTS: Of the 141 surveys, 47 were initiated. The most frequently referenced types of training were on-the-job training and the Internet. Dispensary personnel most commonly used patients' preferences and symptoms as well as personal experiences to determine appropriate strains for patients. The majority of respondents advised patients about precautions and expected effects. Respondents were least likely to advise on drug interactions, or recommend a patient talk to a pharmacist or prescriber. CONCLUSION: Dispensary personnel in Oregon use a variety of resources to learn about medical marijuana. Although formal health or medical training was not indicated, personnel advise on marijuana's effects, use, and product selection. Further study is needed to assess the current training and advising on patients' ability to use medical marijuana safely and effectively.

Efficacy of different targeting agents in the photolysis of interleukin-2 receptor bearing cells.

The multichain interleukin-2 receptor (IL-2R) has been proposed as a target for immunotherapy in the treatment of certain cancers including adult T-cell leukemia and cutaneous T-cell lymphoma as well as certain autoimmune diseases. The IL-2R is abnormally expressed on cells associated with each of these diseases; while normal, non-activated T-cells do not express the receptor. This report describes the selective photolysis of activated and non-activated IL-2R expressing cells using several immunoconjugates synthesized with one of two photosensitizers, hematoporphyrin (HP) or chlorin-e(6) (Ce(6)), covalently linked to IL-2 or an anti-IL-2R antibody. Destruction of IL-2R bearing cells was achieved after photosensitizer internalization and irradiation using all tested photosensitizer conjugates. Chlorin containing conjugates were more effective, by a factor of 4 or more, than HP containing conjugates. Conjugates made with IL-2 were up to 30 times more effective than conjugates that used a monoclonal antibody against the IL-2R for targeting. Activation of the cells to increase IL-2R expression decreased the internalization time required for optimal therapeutic efficacy; however, stimulation of the cell to increase IL-2 secretion greatly reduced conjugate effectiveness. This work could lead to the development of more effective strategies to treat T-cell diseases.
