Circulating tumor DNA predicts venous thromboembolism in patients with cancers.

Background: Despite rapid advances in liquid biopsy for circulating tumor DNA (ctDNA), its prognostic value for venous thromboembolism (VTE) in patients with cancer is underexplored, particularly in underserved and minoritized populations.

Objectives: To evaluate the role of ctDNA in risk stratification for cancer-associated VTE.

Methods: We analyzed data from 1038 cancer patients who underwent ctDNA measurement for oncologic care at a large safety-net hospital system in the United States.

Natural history of cancer-associated splanchnic vein thrombosis.

Background: There is uncertainty in the management of cancer-associated isolated splanchnic vein thrombosis (SpVT).

Objectives: To describe the natural history of SpVT by cancer type and thrombus composition and to review anticoagulation (AC) practices and associated rates of usual-site venous thromboembolism (VTE), major and clinically relevant nonmajor bleeding (MB/CRNMB), recanalization/progression, and mortality.

Methods: We performed a retrospective cohort study in patients with SpVT at 2 cancer care centers in Houston, Texas.

Impact of Insurance Status on Outcomes in Individuals with AIDS-Defining Cancers.

This single-center, retrospective cohort study evaluates whether insurance coverage and Ryan White HIV/AIDS Program assistance are associated with differences in treatment and survival outcomes in Kaposi sarcoma and aggressive non-Hodgkin lymphoma among people with HIV (PWH). Participants were classified as having private, Medicare, Medicaid, or no insurance. Hazard ratios (HRs) for progression and death were estimated using Cox proportional hazards regression models.

Intestinal Tuberculosis Presenting as an Ileocecal Mass in a Renal Transplant Patient.

Abdominal tuberculosis accounts for approximately 5% of tuberculosis cases. However, recognition of this entity can be challenging in the absence of concomitant pulmonary involvement. Immunocompromised and immunosuppressed patients are at elevated risk for this infection and are confronted with increased side effects, drug interactions, and disease complications.

[Numerical analysis of inter-specific relationships in the estuary salt marsh plant community of southern Chongming Dongtan, Shanghai.].

The salt marsh plant communities were investigated with quadrats in the southern Chongming Dongtan. Based on the vegetation coverage and the 2×2 contingency table, 8 common species among the 17 higher plants recorded were analyzed. The variance ratio of overall association, Chi-square test and Spearman rank correlation coefficient were used to describe the relevance and correlations between species pairs.
