Article Abstract
This paper presents a flexible and low-profile frequency selective metasurface (FSMS) resonating at 10 GHz. The proposed FSMS is a single-layer design with stable response under conformal applications. The inter-element capacitance has been enhanced by introducing lumped capacitors. This technique has significantly reduced the size of the unit element (UE) and enabled operation around the 2 GHz frequency band. The proposed capacitive-loaded structure is highly compact with a wideband transmission response featuring 95% fractional bandwidth (1.2 GHz to 3.1 GHz). The proposed FSMS design architecture is easy to reconfigure for any resonant frequency by tuning the inter-element capacitors. Its small size of 5.3 × 5.3 [Formula: see text] enables the design to be used effectively at S, C, and X-band wrapping applications, which is otherwise infeasible with larger UEs. In addition to miniaturization, the design offers high angular stability and polarization insensitivity for different wrapping angles.

Background: Omeprazole, a widely used proton pump inhibitor, has been associated with rare but serious adverse events such as myopathy. Previous research suggests that concurrent use of omeprazole with fluconazole, a potent cytochrome P450 (CYP) 2C19/3A4 inhibitor, may increase the risk of myopathy. However, the contribution of genetic polymorphisms in CYP enzymes remains unclear.

Objectives: The Charlson comorbidity index reflects overall comorbidity burden and has been applied in cardiovascular medicine. However, its role in predicting in-hospital mortality in patients with acute myocardial infarction (AMI) complicated by ventricular arrhythmias (VA) remains unclear. This study aims to evaluate the predictive value of the Charlson comorbidity index in this setting and to construct a nomogram model for early risk identification and individualized management to improve outcomes.

Objectives: Intracranial aneurysm (IA) has an insidious onset, and once ruptured, it carries high rates of mortality and disability. Cardiometabolic factors may be associated with the formation and rupture of IA. This study aims to summarize the application of Mendelian randomization (MR) methods in research on cardiometabolic factors and IA, providing insights for further elucidation of IA etiology and pathogenesis.

Hepatitis C virus (HCV) clearance markedly reduces the risk of hepatocellular carcinoma (HCC); however, HCC continues to develop in a subset of patients, particularly in those with advanced fibrosis or cirrhosis. Leading hepatology societies, including Asian Pacific Association for the Study of the Liver, European Association for the Study of the Liver, American Association for the Study of Liver Diseases, Korean Association for the Study of the Liver, Taiwan Association for the Study of the Liver, and Japan Society of Hepatology, have issued divergent guidelines for HCC surveillance after sustained virologic response, which reflects variations in regional patient populations, healthcare infrastructure, and policy priorities. While traditional risk stratification primarily centers on histological staging of fibrosis, an array of additional host-related factors, including age, sex, alcohol use, metabolic comorbidities, and genetic and epigenetic profiles, further influence individual HCC risks.

In 2016, the NIH designated LGBTQ+ individuals (ie, lesbian, gay, bisexual, transgender, queer, and all sexual and gender minorities) as a health disparities population. The growing interest in studying the health of LGBTQ+ populations merits revisiting the methodological approaches researchers employ. We elucidate how researchers can identify appropriate adjustment sets for causal questions using directed acyclic graphs (DAGs).
