RESUMO
This review analyzes data regarding liver injury associated with COVID-19 infection. We discuss reported effects on the liver from both COVID-19 and COVID-19 treatment as well as pathophysiology, review the potential role of drug-induced liver injury as an etiology of COVID-19-associated liver injury, and touch on other reports of significant outcomes including COVID-19 cholangiopathy and autoimmune hepatitis. Finally, we review the implications of COVID-19 infection in liver transplant recipients.
RESUMO
BACKGROUND: Gastric cancer significantly contributes to cancer mortality globally. Gastric intestinal metaplasia (GIM) is a stage in the Correa cascade and a premalignant lesion of gastric cancer. The natural history of GIM formation and progression over time is not fully understood. Currently, there are no clear guidelines on GIM surveillance or management in the United States. AIM: To investigate factors associated with GIM development over time in African American-predominant study population. METHODS: This is a retrospective longitudinal study in a single tertiary hospital in Washington DC. We retrieved upper esophagogastroduodenoscopies (EGDs) with gastric biopsies from the pathology department database from January 2015 to December 2020. Patients included in the study had undergone two or more EGDs with gastric biopsy. Patients with no GIM at baseline were followed up until they developed GIM or until the last available EGD. Exclusion criteria consisted of patients age < 18, pregnancy, previous diagnosis of gastric cancer, and missing data including pathology results or endoscopy reports. The study population was divided into two groups based on GIM status. Univariate and multivariate Cox regression was used to estimate the hazard induced by patient demographics, EGD findings, and Helicobacter pylori (H. pylori) status on the GIM status. RESULTS: Of 2375 patients who had at least 1 EGD with gastric biopsy, 579 patients were included in the study. 138 patients developed GIM during the study follow-up period of 1087 d on average, compared to 857 d in patients without GIM (P = 0.247). The average age of GIM group was 64 years compared to 56 years in the non-GIM group (P < 0.001). In the GIM group, adding one year to the age increases the risk for GIM formation by 4% (P < 0.001). Over time, African Americans, Hispanic, and other ethnicities/races had an increased risk of GIM compared to Caucasians with a hazard ratio (HR) of 2.12 (1.16, 3.87), 2.79 (1.09, 7.13), and 3.19 (1.5, 6.76) respectively. No gender difference was observed between the study populations. Gastritis was associated with an increased risk for GIM development with an HR of 1.62 (1.07, 2.44). On the other hand, H. pylori infection did not increase the risk for GIM. CONCLUSION: An increase in age and non-Caucasian race/ethnicity are associated with an increased risk of GIM formation. The effect of H. pylori on GIM is limited in low prevalence areas.
RESUMO
BACKGROUND: Patients with chronic conditions often use complex medical regimens. A nurse-led strategy to support medication therapy management incorporated into primary care teams may lead to improved use of medications for disease control. Electronic health record (EHR) tools may offer a lower-cost, less intensive approach to improving medication management. METHODS AND RESULTS: The Northwestern and Access Community Health Network Medication Education Study is a health center-level cluster-randomized trial being conducted within a network of federally qualified community health centers. Health centers have been enrolled in groups of 3 and randomized to (1) usual care, (2) EHR-based medication management tools alone, or (3) EHR tools plus nurse-led medication therapy management. Patients with uncontrolled hypertension who are prescribed ≥ 3 medications of any kind are recruited from the centers. EHR tools include a printed medication list to prompt review at each visit and automated plain-language medication information within the after-visit summary to encourage proper medication use. In the nurse-led intervention, patients receive one-on-one counseling about their medication regimens to clarify medication discrepancies and identify drug-related concerns, safety issues, and nonadherence. Nurses also provide follow-up telephone calls following new prescriptions and periodically to perform medication review. The primary study outcome is systolic blood pressure after 1 year. Secondary outcomes include measures of understanding of dosing instructions, discrepancies between patient-reported medications and the medical record, adherence, and intervention costs. CONCLUSIONS: The Northwestern and Access Community Health Network Medication Education Study will assess the effects of 2 approaches to support outpatient medication management among patients with uncontrolled hypertension in federally qualified health center settings.
