Despite advances in percutaneous coronary procedures, in-stent restenosis remains a significant challenge. Although sirolimus- and paclitaxel-coated balloons are promising alternatives, their comparative safety and efficacy remain uncertain. PubMed, Embase, and Cochrane databases were searched using relevant keywords from inception until August 2025. A total of 11 studies (7 randomized controlled trials and 4 observational cohort studies) were included, comprising 3633 participants overall. The primary outcomes assessed were target lesion revascularization and target lesion failure. Meanwhile, the Secondary outcomes included stent thrombosis, all-cause mortality, myocardial infarction, major adverse cardiovascular events, survival, binary restenosis, and angiographic endpoints (acute gain, diameter stenosis, in-segment late lumen loss, in-lesion late lumen loss, and in-segment minimal lumen diameter). Interstudy heterogeneity was assessed using I ² and X ² statistics ( I ²>50% = significant heterogeneity). Interstudy heterogeneity was low for most outcomes, including all primary clinical endpoints, with moderate heterogeneity observed only for select angiographic measures (notably in-segment late lumen loss and diameter stenosis). Statistical analysis was conducted using R software and RStudio (version 4.4.2), with a P value of < 0.05 indicating statistical significance. This meta-analysis examined studies that compared paclitaxel-coated balloon (PCB) versus standard balloon [sirolimus-coated balloon (SCB)] angioplasty. Regarding primary outcomes, there were no notable variations in target lesion failure [risk ratio (RR), 1.08, 95% CI, 0.90–1.29, P = 0.36] or target lesion revascularization (RR, 1.16, 95% CI, 0.98–1.37, P = 0.08). With all aggregated estimates being nonsignificant, secondary outcomes such as stent thrombosis, all-cause mortality, myocardial infarction, major adverse cardiovascular events, and survival were similar between groups. Angiographic endpoints revealed no discernible variations in late lumen loss (in-lesion and in-segment), acute gain, or diameter stenosis. Nonetheless, the SCB group’s minimal lumen diameter was significantly smaller than that of the PCB group (MD, −0.08 mm, 95% CI, −0.14 to −0.01, P = 0.02). In treating coronary in-stent restenosis, SCB and PCBs show similar overall safety and effectiveness; lesion-specific angiographic variations indicate that customized selection may improve patient outcomes.

Viral hepatitis (VH) remains a leading cause of preventable mortality in the United States (US). Despite advancements in antiviral therapies, disparities in VH-related mortality persist across demographic, racial, and geographic groups. This study analyzes trends in VH-related mortality among US adults between 1999 and 2020 to identify high-risk subgroups and inform public health interventions. This retrospective cohort study analyzed VH-related deaths among US adults (≥25 years). Data were obtained from the CDC WONDER database, with cases identified using the International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) codes B15–B19. Age-adjusted mortality rates (AAMRs) were calculated per 1,00,000 individuals and stratified by age, gender, race and geographical location. Temporal trends in mortality were analyzed by estimating annual percentage changes (APCs) in the AAMRs using the joinpoint regression model. A total of 3,59,035 VH-related deaths were recorded among US adults during 1999 to 2020 with a cumulative overall AAMR of 7.36 (95% CI: 7.33–7.38). Overall, the AAMRs increased significantly from 1999 to 2013 (APC: +3.21; P < .01), followed by a significant decline until 2020 (APC: −5.61; P < .01). Men exhibited higher AAMRs than women, with middle-aged adults (45–64 years) most affected compared to young (25–44 years) and older adults (65 to 85+ years). Non-Hispanic (NH) American Indians/Alaska experienced the highest AAMRs followed by NH Blacks/African Americans, Hispanics, NH Asians/Pacific Islanders and NH Whites populations. Geographically, mortality rates were higher in urban areas than in rural areas, in the Western region relative to other regions and in the District of Columbia compared to other states. Significant disparities in VH-related mortality persist across demographic and geographic subgroups, with particularly higher rates among men, NH American Indian/Alaska Native population, middle-aged adults, and residents of urban and Western US regions. Targeted public health strategies are essential to address these inequities and improve outcomes.
