title: Identification, Semiparametric Efficiency, and Quadruply Robust Estimation in Mediation Analysis with Treatment-Induced Confounding

description: Natural mediation effects are often of interest when the goal is to understand a causal mechanism. However, most existing methods and their identification assumptions preclude treatment-induced confounders often present in practice. To address this fundamental limitation, we provide a set of assumptions that identify the natural direct effect in the presence of treatment-induced confounders. Even when some of those assumptions are violated, the estimand still has an interventional direct effect interpretation. We derive the semiparametric efficiency bound for the estimand, which unlike usual expressions, contains conditional densities that are variational dependent. We consider a reparameterization and propose a quadruply robust estimator that remains consistent under four types of possible misspecification and is also locally semiparametric efficient. We use simulation studies to demonstrate the proposed method and study an application to the 2017 Natality data to investigate the effect of prenatal care on preterm birth mediated by preeclampsia with smoking status during pregnancy being a potential treatment-induced confounder.

title: Evaluating Association Between Two Event Times with Observations Subject to Informative Censoring

description: This article is concerned with evaluating the association between two event times without specifying the joint distribution parametrically. This is particularly challenging when the observations on the event times are subject to informative censoring due to a terminating event such as death. There are few methods suitable for assessing covariate effects on association in this context. We link the joint distribution of the two event times and the informative censoring time using a nested copula function. We use flexible functional forms to specify the covariate effects on both the marginal and joint distributions. In a semiparametric model for the bivariate event time, we estimate simultaneously the association parameters, the marginal survival functions, and the covariate effects. A byproduct of the approach is a consistent estimator for the induced marginal survival function of each event time conditional on the covariates. We develop an easy-to-implement pseudolikelihood-based inference procedure, derive the asymptotic properties of the estimators, and conduct simulation studies to examine the finite-sample performance of the proposed approach. For illustration, we apply our method to analyze data from the breast cancer survivorship study that motivated this research. Supplementary materials for this article are available online.

title: Low-cost ground-based NDVI sensor device for manual and automated crop monitoring

description: Ground-based NDVI sensors are vital for an accurate, localized crop condition and growth assessment, but their high cost and labor-intensive nature limit accessibility. Here, we present a low-cost NDVI sensor device, priced under 250 Euros, which can be utilized both manually as a handheld tool and automatically as a standalone device to address this issue. We calibrated and field validated the low-cost NDVI sensor against a commercial sensor for ground-based NDVI measurements. Our calibration revealed a slight underestimation at higher NDVI values measured from the low-cost sensor, which we adjusted using a correction function. Field validation proved the accuracy of low-cost sensor device, with a high correlation (r² = 0.99; y = 1.04x + 0.003) and good agreement with the reference device, after applying then derived correction function. Further field trial application of the low-cost sensor as a handheld device (manual mode) in Benin and the Philippines for rice and pineapple cultivation, respectively, demonstrated the reliability of the device to monitor crop development and biomass accumulation. An additional field testing in an oat field site in Germany showed that the developed low-cost NDVI sensor, functioning as a standalone automatic device, is robust, reliable and capable to monitor crop development during senescence, through higher temporal resolution NDVI measurements. This study proved the accuracy and reliability of our low-cost NDVI sensor, increasing accessibility to cost-effective, ground-based NDVI crop monitoring solutions.Contains the index of all datasets.

title: The No-Touch Saphenous Vein Harvesting Improves Graft Patency After Off-Pump Coronary Artery Bypass Surgery: A Propensity-Matched Analysis

description: ABSTRACT Introduction: This single-center study of propensity-matched data was performed to assess the effect of the no-touch saphenous vein (NTSV) harvesting technique on early- and long-term outcomes of patients after off-pump coronary artery bypass grafting (OPCABG) in China. Methods: A retrospective analysis of 767 patients who underwent OPCABG in the Beijing Anzhen Hospital (June 2017 to October 2021) was performed, and their data entered the conventional saphenous vein (CSV) harvesting technique group or the NTSV group. In-hospital and follow-up outcomes were evaluated by adjusting baseline characteristics using propensity score matching (1:1). Clinical outcomes and postoperative angiographic results were compared. Results: The saphenous vein graft patency rates at postoperative three months and one year for the NTSV group vs. CSV group were 99.6% vs. 96.2% (P&lt;0.001) and 97.3% vs. 93.1% (P&lt;0.001), respectively. The two matched groups received a significantly different cumulative incidence function of saphenous vein graft occlusion for the longer follow-up period in Kaplan-Meier curves (χ2=4.330, log-rank P=0.037). No difference in early- and long-term mortality or major adverse cardiac and cerebrovascular events (MACCE) were observed between the groups. The rate of MACCE was not statistically significant different between the groups, but there was a tendency favoring the no-touch technique (9.8% CSV vs. 4.8% NTSV; P=0.067). More patients in the NTSV group developed postoperative leg wound exudation (5.4% vs. 1.2%; P=0.032) and skin numbness (22.2% vs. 8.9%; P=0.001) than in the CSV group. Conclusion: The NTSV is an excellent conduit to be used in OPCABG. There remains a need to reduce leg wound complications.
