Early intervention with double balloon enteroscopy for higher yield for inpatient overt obscure gastrointestinal bleeding: A propensity matched analysis.

Background and Aim: Overt obscure gastrointestinal bleeding (OOGIB) is defined as continued bleeding with unknown source despite esophagogastroduodenoscopy (EGD) and colonoscopy evaluation. Small bowel evaluation through video capsule endoscopy (VCE) or double balloon enteroscopy (DBE) is often warranted. We studied the timing of DBE in hospitalized OOGIB patients regarding diagnostic yield, therapeutic yield, and GI rebleeding. Methods: We performed a retrospective review of DBEs performed at a tertiary medical center between November 2012 and December 2020. The inclusion criterion was first admission for OOGIB undergoing DBE. Those without previous EGD or colonoscopy were excluded. Patients were stratified into two groups: DBE performed within 72 h of OOGIB (emergent) and beyond 72 h of OOGIB (nonemergent). Propensity score matching was used to adjust for the difference in patients in the two groups. Logistic regression analysis was used to assess factors associated with diagnostic and therapeutic yield. Kaplan-Meir survival curve showed GI bleed-free survival following initial bleed and was compared using the log rank test. Results: A total of 154 patients met the inclusion criterion, of which 62 had emergent DBE and 92 had nonemergent DBE. The propensity-score-matched sample consisted of 112 patients, with 56 patients each in the emergent and nonemergent groups. Univariate and multivariable logistic regression analysis showed a significant association between VCE and emergent DBE and diagnostic and therapeutic yield (P < 0.05). Emergent DBE patients had increased GI bleed-free survival compared to those in the nonemergent group (P = 0.009). Conclusion: Our data demonstrate that emergent DBE during inpatient OOGIB can impact the overall diagnostic yield, therapeutic yield, and GI rebleeding post DBE.

Dietary Patterns and Prevalent NAFLD at Year 25 from the Coronary Artery Risk Development in Young Adults (CARDIA) Study.

The prevalence of nonalcoholic fatty liver disease is rapidly rising. We aimed to investigate associations of diet quality and dietary patterns with nonalcoholic fatty liver disease (NAFLD) in Black and White adults. We included 1726 participants who attended the Year 20 Exam of the Coronary Artery Risk Development in Young Adults (CARDIA) study and had their liver attenuation (LA) measured using computed tomography at Year 25 (2010-2011). NAFLD was defined as an LA of ≤51 Hounsfield units after the exclusion of other causes of liver fat. The a priori diet-quality score (APDQS) was used to assess diet quality, and dietary patterns were derived from principal components analysis. Univariate and multivariable logistic regression models were used to evaluate the association between the APDQS, dietary patterns, and NAFLD, and were adjusted for Year 20 covariates. NAFLD prevalence at Year 25 was 23.6%. In a model adjusted for age, race, sex, education, alcohol use, physical activity, smoking, and center at Year 25, the APDQS was inversely associated (p = 0.004) and meat dietary pattern was positively associated (p < 0.0001) with NAFLD, while the fruit-vegetable dietary pattern was not significantly associated (p = 0.40). These associations remained significant when additionally adjusting for comorbidities (type 2 diabetes mellitus, dyslipidemia, hypertension), however, significant associations were diminished after additionally adjusting for body mass index (BMI). Overall, this study finds that the APDQS and meat dietary patterns are associated with prevalent NAFLD in mid-life. The associations appear to be partially mediated through higher BMI.

Acute Liver Failure Due to Toxoplasmosis After Orthotopic Liver Transplantation.

Solid organ transplant recipients are at risk for a wide range of opportunistic infections, the most common being cytomegalovirus. These infections may occur as reactivation of latent disease, donor-derived, or de novo. In this article, we present a case of acute liver failure secondary to toxoplasmosis following orthotopic liver transplantation. Our patient presented 5 weeks after orthotopic liver transplantation with altered mental status and fatigue. She was found to have disseminated cytomegalovirus infection, which resolved with intravenous ganciclovir; however, she subsequently developed acute liver failure due to toxoplasmosis, which is hypothesized to be donor-derived. Infection with Toxoplasma may be asymptomatic in the immunocompetent host; however, in immunocompromised hosts, such as solid organ transplant recipients, this infection can be life threatening. Though prophylaxis with trimethoprim-sulfamethoxazole may prevent infections with Toxoplasma, it is often held for renal dysfunction, hyperkalemia, or other side effects, placing patients at risk. With 13 cases now reported, routine screening of donor and recipient for toxoplasma exposure may be warranted.

A community-based innovative model of care for the management of severe bacterial infections in persons who use injection drugs.

The opioid crisis and complications related to injection drug use are a public health emergency. The combination of addiction and injection drug use is a devastating double-edged sword: it predisposes patients to severe life-threatening infections like endocarditis, and epidural abscess, as well as to disorganized behaviour and impaired decision-making that interferes with the completion of prolonged courses of required antibiotic therapy. Poverty and stigma add further fuel to the fire. The Community Transitional Care Team (CTCT) is a revolutionary community-based short-term residence where people who inject drugs can stay to complete their course of antibiotics. We present the case of a young woman struggling with addiction, tremendous social barriers to health, and life threating Staphylococcus aureus infection that highlights the benefits of strong, community-based, and individualized models of patient care.

La crise des opioïdes et les complications liées à la consommation de drogues injectables représentent une urgence de santé publique. L'association de la dépendance et de la consommation de drogues injectables est une épée à double tranchant dévastatrice. En effet, elle prédispose les patients à de graves infections au potentiel mortel comme l'endocardite et l'abcès épidural, de même qu'à une désorganisation du comportement et à une altération des décisions qui compromettent les antibiothérapies prolongées. La pauvreté et l'opprobre jettent de l'huile sur le feu. L'équipe communautaire de soins transitoires est une résidence communautaire de courte durée révolutionnaire où les personnes qui s'injectent des drogues peuvent habiter pour terminer leur antibiothérapie. Les auteurs présentent le cas d'une jeune femme aux prises avec la dépendance, d'énormes obstacles sociaux en matière de santé et une infection à Staphylococcus aureus au potentiel mortel qui fait ressortir les avantages de modèles communautaires et personnalisés robustes pour les soins aux patients.

Fentanyl and heroin contained in seized illicit drugs and overdose-related deaths in British Columbia, Canada: An observational analysis.

BACKGROUND: Due to the alarming rise in opioid-related overdose deaths, a public health emergency was declared in British Columbia (BC). In this study, we examined the relationship between illicit fentanyl and heroin found in seized drugs and illicit overdose deaths in BC. METHODS: An observational cross-sectional survey was conducted using BC data from Health Canada's Drug Analysis Service, which analyzes drug samples seized by law enforcement agencies, and non-intentional illicit overdoses from the BC Coroner's Service, from 2000 to 2016. Initial scatter plots and subsequent multivariate regression analysis were performed to describe the potential relationship between seized illicit fentanyl samples and overdose deaths and to determine if this differed from seized heroin and overdose deaths. Fentanyl samples were analyzed for other drug content. RESULTS: Fentanyl is increasingly being found combined with other opioid and non-opioid illicit drugs. Strong positive relationships were found between the number of seized fentanyl samples and total overdose deaths (R2 = 0.97) as well as between seized fentanyl and fentanyl-detected overdose deaths (R2 = 0.99). A positive association was found between the number of seized heroin samples and total overdose deaths (R2 = 0.78). CONCLUSION: This research contributes to the expanding body of evidence implicating illicit fentanyl use (often combined with heroin or other substances) in overdose deaths in BC. Policy makers and healthcare providers are urged to implement drug treatment and harm reduction strategies for people at risk of overdose associated with current trends in illicit opioid use.
