Sarcopenia as a Preoperative Risk Stratification Tool among Older Adults with Inflammatory Bowel Disease.

Sarcopenia, defined as a loss of muscle mass and function, is a physiologic factor that has been implicated as a predictor of adverse postoperative outcomes in many older adult populations. However, data related to sarcopenia in older adults with inflammatory bowel disease (IBD) remain limited. Older adults with IBD are particularly vulnerable to adverse postoperative outcomes, in part, due to muscle depletion from systemic inflammation, malnutrition, and reduced physical activity. However, few patients undergo routine muscle evaluation as a part of preoperative assessment. Moreover, cut-off values for measures of sarcopenia in the literature are modeled after non-IBD populations. The lack of standardized measures and values for sarcopenia in the IBD patient population has led to heterogenous findings and a paucity of preoperative risk stratification tools. Therefore, we aim to explore the scope of sarcopenia as a preoperative risk stratification tool among older adults with IBD.

Racial Disparity in HCV Demographics and Treatment Between Interferon Era (2002-2003) and Direct Acting Anti-viral Era (2019).

Introduction  Direct-acting antiviral (DAA) treatment increased the sustained viral response (SVR) rate of patients with the hepatitis C virus (HCV) and eliminated response disparities between African American (AA) and non-AA patients seen with interferon (IFN). The aim of this study was to compare 2019 HCV patients (DAA era) to patients from January 1, 2002 and December 31, 2003 (IFN era) in our predominantly AA clinic population. Methods We extracted data on 585 HCV patients seen in 2019 (DAA era) and compared them to 402 patients seen in the IFN era. Results Most HCV patients were born between 1945 and 1965, but in the DAA era more younger patients were identified. Non-AA patients in both eras were less likely to be infected with genotype 1 compared to AA (95% vs 54%, P<0.001). Fibrosis was not increased in the DAA Era as compared to the IFN era as assessed either by serum-based assays (APRI, FIB-4) or transient elastography (FibroScan) (DAA era) vs biopsy (IFN era). More patients were treated in 2019 compared to 2002-2003 (159/585=27% vs 5/402=1%). For untreated patients, subsequent treatment within one year of the initial visit was low and similar in both eras (35%). Conclusion There continues to be a need to screen patients born between 1945 and 1965 for HCV as well as to identify increasing numbers of patients below this age cohort. Even though current therapies are oral, highly effective, and can be 8-12 weeks in duration, significant numbers of patients were not treated within a year of first visit.
