Evaluation of methotrexate Pharmacogenomic variation to predict acute neurotoxicity in children with acute lymphoblastic leukemia.

Background: Methotrexate is an important component of curative therapy in childhood acute lymphoblastic leukemia (ALL), but the role of genetic variation influencing methotrexate clearance and transport in toxicity susceptibility in children with ALL is not well established. Therefore, we evaluated the association between suspected methotrexate pharmacogenomic variants and methotrexate-related neurotoxicity.

Methods: This study included children (aged 2-20 years) diagnosed with ALL (2005-2019) at six treatment centers in the southwest United States.

Tramadol as a fentanyl adulterant: Prevalence and management in a ToxIC Fentalog study prospective cohort.

Background: Tramadol is an adulterant of illicit opioids. As it is a serotonin-norepinephrine reuptake inhibitor as well as a μ-opioid agonist, tramadol adulteration may worsen overdose signs and symptoms or affect the amount of naloxone patients receive.

Methods: This is a multicenter, prospective cohort of adult patients with suspected opioid overdoses who presented to one of eight United States emergency departments and were included in the Toxicology Investigators Consortium's Fentalog Study.

Neighborhood Factors related to Cancer Screening in Texas: a spatioecological study.

Introduction: To examine the associations of neighborhood socioeconomic status (nSES), ethnic enclaves, residential Black segregation with screening for breast, cervical and colorectal (CRC) cancers across the state of Texas (TX).

Methods: Using an ecologic study design, spatial clustering of low breast, cervical and CRC screening rates were identified across TX census tracts using local Moran's I statistics. Binomial spatial probit regression was used to estimate the associations between nSES, Hispanic/Latino and Asian American (AA) ethnic enclave neighborhoods and residential Black segregation with geospatial clusters of low screening, adjusting for behavioral characteristics.

Positive association of oscillometrically estimated baseline arterial stiffness with incident diabetes and prediabetes: A large population-based cohort study.

Aims: This large population-based study aimed to investigate whether arterial stiffness, assessed oscillometrically, was associated with incident diabetes/prediabetes.

Methods: The study sample comprised 4240 participants from the Vitamin D Assessment (ViDA) Study (mean±SD age = 66 ± 8). Arterial stiffness was assessed from 5 April 2011-6 November 2012 by way of aortic PWV (aPWV) and estimated carotid-femoral PWV (ecfPWV).

Environmental Stress and Resource Availability Affect the Maintenance of Genetic Variation in a Dominant Marsh Plant (Spartina alterniflora).

Changes in genetic variation, and particularly documented declines in genetic diversity, influence not only evolutionary potential but also current ecological function. Given this context, it is essential to understand what abiotic and biotic factors promote or disrupt the maintenance of genetic variation in natural populations. To address this knowledge gap in the context of salt marsh plants, we established a three-year field experiment, testing the independent and interactive effects of nutrient availability and physical stress on the maintenance of plant (Spartina alterniflora) genotypic diversity.
