RESUMEN

Alcohol use disorders (AUD) and alcohol-associated liver disease (ALD) have growing impacts on public health, yet many do not receive evidence-based care. People with co-occurring AUD and ALD, especially those in rural communities with less access to specialty care, are most in need of novel integrated care models. The use of telehealth to facilitate co-location within an integrated care model may help to improve access to AUD and ALD care while reducing barriers and improving recovery outcomes for both the substance use disorder and liver disease.

RESUMEN

BACKGROUND: Myocarditis is being increasingly reported as a potential complication of both Pfizer-BioNTech and Moderna vaccines for COVID-19. One thousand five hundred and twenty-two cases were reported as of September 02, 2021, as per CDC's (Centers for Disease Control) vaccine adverse event reporting system. Most of the published data is available in the form of case reports and series. There is a need to compile the demographic data, clinical features, and outcomes in these patients.  Methods: A systematic search was conducted in PubMed, Embase, Web of science, and google scholar for published literature between January 01, 2020, and July 17, 2021. Individual data of 69 patients were pooled from 25 qualifying case reports and case series. RESULTS: The median age of onset was 21 years. 92.7% of the patients were male. 76.8% of patients received the Pfizer-BioNTech vaccine, and 23.2% received the Moderna vaccine. 88.5% developed symptoms after the second dose. Patients were admitted to the hospital a median of three days post-vaccination. All the patients had chest pain and elevated troponin. The myocarditis was confirmed on cardiac MRI in 87% of the patients. Most of the patients had late gadolinium enhancement on MRI. The median length of stay was four days. All the reported patients recovered and were discharged. CONCLUSION: Post-mRNA vaccination myocarditis is seen predominantly in young males within a few days after their second dose of vaccination. The pathophysiology of myocarditis is not well known. The prognosis is good as all the reported patients recovered. The presence of late gadolinium enhancement on cardiac MRI indicated myocardial necrosis/fibrosis and further studies are needed to establish the long-term prognosis of the condition.

RESUMEN

The intestinal epithelium requires self-renewal and differentiation in order to function and adapt to pathological diseases such as inflammatory bowel disease, short gut syndrome, and ulcers. The rodent Slfn3 protein and the human Slfn12 analog are known to regulate intestinal epithelial differentiation. Previous work utilizing a pan-Slfn3 knockout (KO) mouse model revealed sex-dependent gene expression disturbances in intestinal differentiation markers, metabolic pathways, Slfn family member mRNA expression, adaptive immune cell proliferation/functioning genes, and phenotypically less weight gain and sex-dependent changes in villus length and crypt depth. We have now created a Vil-Cre specific Slfn3KO (VC-Slfn3KO) mouse to further evaluate its role in intestinal differentiation. There were increases in Slfn1, Slfn2, Slfn4, and Slfn8 and decreases in Slfn5 and Slfn9 mRNA expression that were intestinal region and sex-specific. Differentiation markers, sucrase isomaltase (SI), villin 1, and dipeptidyl peptidase 4 and glucose transporters, glucose transporter 1 (Glut1), Glut2, and sodium glucose transporter 1 (SGLT1), were increased in expression in VC-Slfn3KO mice based on intestinal region and were also highly female sex-biased, except for SI in the ileum was also increased for male VC-Slfn3KO mice and SGLT1 was decreased for both sexes. Overall, the variations that we observed in these VC-Slfn3KO mice indicate a complex regulation of intestinal gene expression that is sex-dependent.
