Objective: To investigate the association between cfDNA levels measured during non-invasive prenatal testing (NIPT) and the risk of pregnancy complications in a Chinese population.
Methods: This was a retrospective cohort study of 831 pregnant women who underwent NIPT at 12-22 weeks of gestation. Maternal plasma cfDNA levels and pregnancy outcomes were obtained from NIPT Screening System and hospitalization records, respectively. Logistic regression analysis was performed to investigate the relationship between cfDNA levels and pregnancy complications (after adjusting for confounding factors).
Results: Maternal cfDNA levels were significantly higher in women diagnosed with intrahepatic cholestasis of pregnancy (ICP) and preeclampsia (PE) compared to pregnant women with non-pregnancy complications (NPC) (median cfDNA 7.07, 6.42 vs. 5.99 ng/mL). Increase in cfDNA levels were associated with an increased risk for ICP (adjusted-OR = 1.20, 95% CI: 1.07-1.34) and PE (adjusted-OR = 1.14, 95% CI: 1.02-1.26). In addition, increase in cfDNA levels were associated with risk of GDM, and was dependent on maternal age (maternal age ≥ 35 years: adjusted-OR = 1.16, 95% CI: 1.04-1.29; maternal age < 35 years: adjusted-OR = 0.85, 95% CI: 0.73-0.99).
Conclusion: Maternal plasma cfDNA levels measured during NIPT are associated with pregnancy complications (ICP, PE and GDM). Maternal age may be an important effect modifier for the association between plasma cfDNA levels and GDM.

Metastasis in patients with oral squamous cell carcinoma has been associated with a poor prognosis. However, sensitive and reliable tests for monitoring their occurrence are unavailable, with the exception of PET-CT. Circulating tumor cells and cell-free DNA have emerged as promising biomarkers for determining treatment efficacy and as prognostic predictors in solid tumors such as breast cancer and colorectal cancer.

Background: Esophageal cancer (ECa) is one of the most deadly cancers, with increasing incidence worldwide and poor prognosis. While endoscopy is recommended for the detection of ECa in high-risk individuals, it is not suitable for large-scale screening due to its invasiveness and inconvenience.
Methods: In this study, a novel gene methylation panel was developed for a blood-based test, and its diagnostic efficacy was evaluated using a cohort of 304 participants (203 cases, 101 controls).

Purpose: Current methods for glioma response assessment are limited. This study aimed to assess the technical and clinical feasibility of molecular profiling using longitudinal intracranial CSF from patients with gliomas.
Experimental Design: Adults with gliomas underwent longitudinal intracranial CSF collection via Ommaya reservoirs or ventriculoperitoneal shunts.

The clinical implications of placental chromosomal mosaicism can be challenging for patients and health care providers. Key considerations include the specific characteristics of the chromosomal abnormality (such as size, gene content, and copy number), the timing of the mosaicism's onset during embryogenesis or fetal development, the types of tissues involved, and the level of mosaicism (the ratio of normal to abnormal cells within those tissues). Genetic counseling can help inform patients about the chances of having a live-born child with a chromosomal abnormality.

Background: Epithelial ovarian cancer (EOC) is a lethal form of gynecological malignancy. Some EOC patients experience relapse after standard primary debulking surgery (PDS) and adjuvant chemotherapy (ACT). Identifying molecular residual disease (MRD) by circulating tumor DNA (ctDNA) detection can timely signal the potential for relapse.
