Summary: This study assessed the clinical utility of subclinical hypothyroidism (SCH) marker, elevated thyroid-stimulating hormone (TSH), and thyroid antibodies in predicting gestational diabetes mellitus (GDM). The results showed a positive correlation between increased TSH levels and the presence of thyroid antibodies with the risk of GDM. Patient age, TSH 4 IU/mL, and anti TPO Ab > 35 IU/mL were identified as significant predictors of GDM, improving the screening performance in the first trimester of pregnancy.

Summary: Recently proposed concepts regarding the nature and assessment of the thyroid state have provided a more consistent model with empirical evidence. Instead of discrete thyroid states, peripheral organ parameters are continuously associated with thyroid function. Thyroid hormone levels, particularly free thyroxine, appear to be better indicators of the thyroid state than thyrotropin levels. However, there are various factors that complicate the assessment of the correlations between the thyroid state and pregnancy outcomes. The value of treating mild abnormalities and the need for improvements in thyroid hormone assays in pregnancy are uncertain. Further investigation may be better based on thyroid hormone levels.

Summary: This study aimed to determine trimester-specific reference intervals (RI) for thyroid function parameters in pregnant women. The results showed that serum TSH RI ranged from 0.34-3.81 mU/L in the first trimester and gradually increased in the second and third trimesters. FT4 and FT3 concentrations progressively decreased during pregnancy. These findings are important for accurately assessing thyroid function in pregnant women.

Summary: Posthemithyroidectomy women have low adherence to thyroid function surveillance, and the publication of the 2017 ATA guidelines did not increase the surveillance rate. Improved patient education on the risk of gestational hypothyroidism following hemithyroidectomy and better communication among treating surgeons, obstetricians, and endocrinologists may improve these rates.

Summary: This article addresses the stability and stabilization of almost periodic piecewise linear systems (APPLSs) with uncertain dwell time of subsystems. A novel mixed-mode time-varying Lyapunov function is constructed, considering the uncertainty in dwell time for the first time. A sufficient condition is proposed to guarantee the exponential stability of the system, where the switching instants over each period are unknown and inaccessible except their bounds. Additionally, a periodic time-scheduled state-feedback control approach is developed to stabilize the APPLS affected by dwell time uncertainty and possibly unstabilizable subsystem dynamics. The effectiveness of the proposed approach is demonstrated through a numerical example involving comparative case studies.

Summary: This study describes an Argonaute protein (MhAgo) from Marinitoga hydrogenitolerans that exhibits all eight cleavage activities. MhAgo shows preference for specific nucleotides and mismatches in the guideRNA can significantly impair its cleavage efficiency. The study also unveils the plasmid cleavage activity mediated by 5'OH-guide RNA (gRNA). These findings enhance our understanding of pAgos and pAgo-based techniques.

Summary: In this study, a new Argonaute protein called TsAgo was identified from Tepiditoga spiralis. TsAgo, similar to other reported proteins, prefers 5'OH-gRNA. It has been shown that TsAgo has DNA and RNA cleavage activity, can tolerate mismatches in certain regions of guides, and exhibits a stronger binding affinity for 5'OH-gRNA. Importantly, TsAgo can function as an RNA-guided programmable nuclease to cut plasmid DNA at high temperatures.

Summary: In this study, we propose a domain adaptive graph infomax method that computes node representations through neighborhood aggregation and maximizes mutual information between node representations and global summaries to encode global structural information. Conditional adversarial networks are used to reduce the domain discrepancy by aligning the multimodal distributions of node representations. Experimental results on real-world datasets validate the performance of our method in comparison with state-of-the-art baselines.

Summary: Image processing enhances the practical value of the eye-in-hand camera for quantitative measurement. This article proposes a fusion of visual information and sparse strain data collected from fiber Bragg gratings to improve continuum robot pose estimation. The integration of the proposed F-emp pose estimation method reduces sensing limitations caused by visual obstacles and lighting variations. A hybrid controller combining kinematics and data-driven algorithms achieves fast convergence and high accuracy using the fused pose feedback. The online-learning error compensator significantly improves target tracking performance.

Summary: The high cost of data labeling results in node label shortage. To address this, a graph-based semi-supervised learning method is proposed, which leverages unlabeled nodes to train together with scarce labeled nodes. An attention-based aggregator is designed to generate node representations by aggregating information from neighboring nodes, and adversarial training is employed to improve robustness and generalization.

Summary: This study compared pregnancy outcomes of patients with gestational transient thyrotoxicosis (GTT) and Graves' disease (GD) in the first trimester. The results showed that the incidence of gestational diabetes mellitus (GDM) was higher in the GTT group compared to the normal thyroid function (NTF) group. The untreated and treated GD groups had a higher risk of premature delivery, gestational hypertension, and miscarriage compared to the NTF group. Early diagnosis of GTT and GD, as well as appropriate treatment for GD, may improve pregnancy outcomes.

Summary: We examine the impact of uncertainty of uncertainty (UOU) on corporate accounting conservatism and find a positive association. Mechanism analysis reveals that under UOU, creditors' demand for real information drives an increase in accounting conservatism. Further analysis shows that the effect of UOU is more pronounced in non-SOEs and firms with weak external monitoring mechanisms. Our study highlights the significant role of contract demand in corporate governance under uncertainty about levels of uncertainty.
