Gut inflammatory diseases cause microbial dysbiosis. Human immunodeficiency virus-1 (HIV) infection disrupts intestinal integrity, subverts repair/renewal pathways, impairs mucosal immunity and propels microbial dysbiosis. However, microbial metabolic mechanisms driving repair mechanisms in virally inflamed gut are not well understood. We investigated the capability and mechanisms of gut microbes to restore epithelial barriers and mucosal immunity in virally inflamed gut by using a multipronged approach: an in vivo simian immunodeficiency virus (SIV)-infected nonhuman primate model of HIV/AIDS, ex vivo HIV-exposed human colorectal explants and primary human intestinal epithelial cells. SIV infection reprogrammed tryptophan (TRP) metabolism, increasing kynurenine catabolite levels that are …

Methodological And Clinical Concerns In The Study On Postpartum Hypertension Management, Takaki Tanamoto, Kyosuke Kamijo, Yusuke Tsutsumi, Tetsuya Kawakita

Department of Obstetrics & Gynecology Faculty Publications

[Introduction] We read with interest the recent study by Rosenfeld et al.¹ However, we have several clinical and methodological concerns about this study.¹

First, this study's propensity score matching (PSM) lacked key clinical confounders, including perinatal risk factors and the highest systolic/diastolic blood pressures. Smoking, alcohol use, and multifetal gestation, which influence blood pressure during pregnancy,²,³ potentially affect both primary and secondary outcomes. Additionally, the authors did not report standardized mean differences before and after PSM, which are essential for assessing balance.⁴

Association Between The Intensity Of Exercise In The First Trimester And Early Second Trimester And The Risk Of Gestational Diabetes, Takaki Tanamoto, Misa Hayasaka, Tetsuya Kawakita

Department of Obstetrics & Gynecology Faculty Publications

Objective

Although some studies show that exercise decreases the incidence of gestational diabetes mellitus (GDM), the optimal exercise intensity during pregnancy remains unclear. We examined GDM risk according to exercise intensity in pregnant individuals.

Methods

We analyzed data from the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers‐to‐Be (nuMoM2b), a prospective study enrolling nulliparous individuals in the first trimester. Participants with pregestational diabetes or delivery before 20 weeks were excluded. Exercise intensity during the first (6–13 weeks’ gestation) and early second (16–21 weeks’ gestation) trimesters was categorized by metabolic equivalent of task hours per week (MET‐hr/week) as none, low intensity (< 7.5), moderate intensity (7.5–14.9), or high intensity (≥ 15). The primary outcome was GDM; secondary outcomes included preeclampsia, gestational hypertension, preterm birth, small‐for‐gestational‐age birth, and stillbirth. Adjusted relative risks (aRRs) with 95% confidence intervals (CIs) were calculated using a generalized linear mixed‐effects model with a Poisson distribution and robust error variance, controlling for the random effects of individuals and potential confounders.

Background: In 2017, the American Heart Association (AHA) and American College of Cardiology updated their hypertension guidelines for the nonpregnant population, lowering the diagnostic thresholds to systolic blood pressure ≥130 mmHg or diastolic blood pressure ≥80 mmHg. This reclassification has raised important questions regarding whether blood pressure (BP) values previously considered within the normal range in pregnancy may, in fact, confer an increased risk for hypertensive disorders of pregnancy (HDPs).

Objective: To evaluate the association between first-trimester BP classified by AHA thresholds and the subsequent development of HDPs.

Study design: This was a secondary analysis of a prospective, multicenter cohort …

Timing Of Delivery In Preeclampsia: Time To Reconsider?, Rebecca Horgan, Ahmed S. Z. Moustafa, Mackenzie Mchugh, Tetsuya Kawakita, Baha Sibai, George Saade

Department of Obstetrics & Gynecology Faculty Publications

The article discusses the need to reassess the timing of delivery in cases of preeclampsia, a condition affecting 2%–8% of pregnancies and linked to significant maternal and neonatal risks. It highlights that existing guidelines, primarily based on older studies, may not adequately reflect current clinical practices and advancements in neonatal care. The authors suggest that planned delivery at 34–36 weeks of gestation may offer maternal benefits without increasing short-term neonatal morbidity, while also emphasizing the importance of considering long-term outcomes for both mothers and infants. They advocate for further research, including large-scale randomized trials, to better understand the implications of …

Online Learning-Driven Human Intent Estimation And Control For Human-Robot Interaction, Irfan Ganie, S. Jagannathan

Electrical and Computer Engineering Faculty Research & Creative Works

This paper presents a novel Stackelberg-game theoretic multilayer-online learning framework for cooperative control of nonlinear Physical Human-Robot Interaction (pHRI), where the human is modeled as the leader guiding a robot follower. This hierarchical interaction is captured as a dynamic Stackelberg game, with the human's intention estimated in real-time through online multilayer neural networks (MNNs). We introduce SVD-based weight update laws for actor-critic MNNs, which approximate value functions and control inputs for both human and robot, eliminating the need for predefined basis functions. In this framework, the human objective is first inferred and used to guide the robot actions by shaping …

Improved Optimal Tracking Of Uncertain Nonlinear Discrete-Time Systems Using Experience Replay, Maxwell Geiger, Sarangapani Jagannathan

Electrical and Computer Engineering Faculty Research & Creative Works

This paper addresses the infinite horizon optimal tracking control problem for partially uncertain control-affine nonlinear discrete-time (DT) systems, where the control input dynamics are known. Multi-layer critic and actor neural networks (MNNs) are utilized for online estimation of the infinite horizon value function and optimal control input. The NN weights are tuned online using a direct temporal difference error (TDE)-driven learning approach, which modifies the singular values of the gradient with respect to the NN weights to accelerate their convergence. The critic NN uses a novel experience replay technique to improve sample efficiency without introducing biased TDEs and guarantee the …

Multi-Model Safe Neuro-Optimal Output Tracking Control Of Autonomous Surface Vessels With Explainable Ai, Behzad Farzanegan, S. Jagannathan

Electrical and Computer Engineering Faculty Research & Creative Works

This paper presents a safety-aware deep reinforcement learning (DRL)-based trajectory tracking control of autonomous surface vessels (ASVs). A multilayer neural network (MNN) observer estimates the ASV's state and uncertain dynamics. By utilizing the estimate state vector from the observer, a safety-aware DRL-based optimal policy is formulated using control barrier function (CBF) and Karush-Kuhn-Tucker (KKT) conditions. An actor-critic MNN with singular value decomposition (SVD)-based update mitigates vanishing gradients. To enhance adaptability, an online safe lifelong learning (SLL) scheme counters catastrophic forgetting across varying ASV dynamics. The Shapley Additive Explanations (SHAP) method identifies key features influencing the control policy. Simulations on an …

Reinforcement Learning-Based Nonlinear Optimal Discrete-Time Control Of Power Systems, Vijay Kumar Singh, Behzad Farzanegan, S. Jagannathan

Electrical and Computer Engineering Faculty Research & Creative Works

This paper presents a partially model-free adaptive optimal tracking control method for power systems, specifically targeting a synchronous generator connected through a reactive transmission line. By integrating the tracking error dynamics with reference trajectory dynamics, an augmented system is created. A discounted performance function is introduced to address the nonlinear tracking problem optimally. Unlike traditional methods that compute feedforward and feedback terms separately, the proposed approach calculates both simultaneously by minimizing the discounted performance function. The discrete-time tracking Bellman and Hamilton-Jacobi-Bellman (HJB) equations are derived, and a reinforcement learning (RL)-based technique is employed to solve the optimal policy online without …
