Modification of asthma treatment efficacy by healthcare access: A reanalysis of AsthmaNet Step-Up Yellow Zone Inhaled Corticosteroids to Prevent Exacerbations (STICS) clinical trial.

Background: While randomized controlled trials (RCTs) in asthma management are designed to balance known and unknown variables across treatment groups, including social and environmental co-exposures, it remains important to consider how these co-exposures influence disease progression and treatment outcomes. The importance of considering socio-environmental co-exposures in the context of asthma is twofold: 1) asthma disproportionately affects low-income urban communities, where air pollution and chronic stress are pervasive; and 2) despite the wide range of asthma treatments, inadequate disease control persists.

Methods: In the present ancillary study of the Step-Up Yellow Zone Inhaled Corticosteroids to Prevent Exacerbations (STICS) RCT, we investigated how socio-environmental factors, such as air pollution exposure and healthcare access, modify the effect of inhaled corticosteroid (ICS) therapy in children with asthma.

The Impact of Using Standardized Autism Screening on Referral to Specialist Evaluation for Young Children on the Autism Spectrum: A Cluster-Randomized Controlled Trial.

Objective: We tested whether the implementation of standardized, high-fidelity screening for autism during routine well-child check-ups results in the following: increasing the number of children with suspected autism referred to diagnostic evaluation; lowering the age at which they are referred; and facilitating autism diagnosis for children across a more diverse range of demographic backgrounds and clinical presentations, including those with subtle manifestations.

Method: As part of a multi-site cluster randomized trial, pediatric practices were randomly assigned to an experimental condition involving training and supervision in the universal, standardized, high-fidelity implementation of the Modified Checklist for Autism in Toddlers, Revised with Follow-Up (M-CHAT-R/F), or a usual care condition. Children in both conditions identified as having a high likelihood of autism during well-child visits were referred to a diagnostic evaluation conducted by clinicians naive to referral source.

Impact of Polypharmacy on Symptoms and Health Outcomes in Older Adults With and Without Alzheimer's Disease and Related Dementias.

Background: There is a critical gap in understanding the symptom experience and health outcomes of older adults with and without Alzheimer's Disease and related dementias (ADRD) and polypharmacy (PPY). The primary aim of the study was to compare the number of symptoms experienced over time in older adults with and without ADRD by polypharmacy status. The secondary aim was to examine the trajectory of physical function and health outcomes over time in each group.

Factors associated with venous thromboembolism pharmacoprophylaxis initiation in hospitalized medical patients: the Medical Inpatients Thrombosis and Hemostasis study.

Background: Although guidelines recommend risk assessment for hospital-acquired venous thromboembolism (HA-VTE) to inform prophylaxis decisions, studies demonstrate inappropriate utilization of pharmacoprophylaxis in hospitalized medical patients. Predictors of pharmacoprophylaxis initiation in medical inpatients remain largely unknown.

Objectives: To determine factors associated with HA-VTE pharmacoprophylaxis initiation in adults hospitalized on medical services.

Association of Urinary Cadmium Concentration With Cognitive Impairment in US Adults: A Longitudinal Cohort Study.

Background And Objectives: Studies have indicated that cadmium (Cd) exposure is associated with neurotoxicity. However, data linking Cd exposure to cognitive impairment are sparse. We aimed to investigate the association between urinary Cd concentration and cognitive impairment in US adults.
