Outcomes of Segmentectomy With or Without Preoperative Biopsy in Non-Small Cell Lung Cancer (NSCLC).

Background: There is a discussion amongst oncologic societies regarding the necessity of preoperative biopsy prior to resection in lung cancer. We aim to examine outcomes of segmentectomy with or without preoperative biopsy in non-small cell lung cancer (NSCLC) patients.

Methods: A retrospective cohort study was conducted utilizing the National Cancer Database.

Sexually dimorphic cardiovascular impacts of prenatal exposure to a real-life environmental chemical mixture in adult offspring.

Cardiovascular disease (CVD) is a leading cause of death that is sexually dimorphic. This study used an ovine model to investigate whether maternal exposure to an environmental chemical (EC) mixture (biosolids) prior to and throughout pregnancy, affected offspring cardiovascular (CV) structure and function in adulthood. CV function of male and female offspring from ewes grazed on either conventionally fertilised (control, C) or biosolids-treated pasture (B) was assessed.

Medicaid Expansion is Associated with Differences in Local Therapy for Non-small Cell Lung Cancer.

Background: Medicaid expansion under the Affordable Care Act aimed to expand healthcare access, improve quality, and reduce costs. The effects of Medicaid expansion on receipt of local therapy for lung cancer are unknown.

Methods: We utilized the National Cancer Database to conduct a retrospective analysis of patients with clinical T1-2, N0, M0 non-small cell lung cancer (NSCLC) without neoadjuvant treatment.

Estimating model parameters of a mathematical model for hand motion during cylindrical grasps.

This paper presents parameter estimation for the passive moment and musculoskeletal scaling coefficients of a mathematical model describing the equations of motion of human finger segments. A novel musculoskeletal model was used as the actuator and parameter estimation was performed by least squares optimization of the differences between angular data from a motion capture system, and the solutions to the equations of motion of our model. The parameter estimates determined are unique to the individual and the dataset.
