Electrochemical‐Genetic Programming of Protein‐Based Magnetic Soft Robots for Active Drug Delivery

Advanced Science, EarlyView.
This manuscript presents a protein‐based soft robot for active drug delivery. Stimuli‐responsive protein is rationally designed and processed into the substrate of robots. Superparamagnetic Fe3O4 nanoparticles are patterned on the substrate using an electrochemical method, enabling the robot to respond to external physical fields.

Propensity Score Analysis with Guaranteed Subgroup Balance [PDF]

arXiv
Estimating the causal treatment effects by subgroups is important in observational studies when the treatment effect heterogeneity may be present. Existing propensity score methods rely on a correctly specified propensity score model. Model misspecification results in biased treatment effect estimation and covariate imbalance.

Regression-based proximal causal inference for right-censored time-to-event data [PDF]

arXiv
Unmeasured confounding is one of the major concerns in causal inference from observational data. Proximal causal inference (PCI) is an emerging methodological framework to detect and potentially account for confounding bias by carefully leveraging a pair of negative control exposure (NCE) and outcome (NCO) variables, also known as treatment and outcome

Surgical and Oncological Outcomes of Conversion Surgery After Hepatic Arterial Infusion Chemotherapy for Initially Unresectable Locally Advanced Hepatocellular Carcinoma

Annals of Gastroenterological Surgery, EarlyView.
Conversion surgery for HCC. ABSTRACT Background Since 2013, we have performed conversion surgery after hepatic arterial infusion chemotherapy (HAIC) for initially unresectable locally advanced hepatocellular carcinoma (LA‐HCC). Methods Between 2013 and 2021, we assessed the surgical and oncological outcomes and pathological findings of patients with LA‐

Efficient estimation of average treatment effects with unmeasured confounding and proxies [PDF]

arXiv
One approach to estimating the average treatment effect in binary treatment with unmeasured confounding is the proximal causal inference, which assumes the availability of outcome and treatment confounding proxies. The key identifying result relies on the existence of a so-called bridge function.
