Purpose: Implicit, unconscious biases in medicine are personal attitudes about race, ethnicity, gender, and other characteristics that may lead to discriminatory patterns of care. However, there is no consensus on whether implicit bias represents a true predictor of differential care given an absence of real-world studies. We conducted the first real-world pilot study of provider implicit bias by evaluating treatment parity in prostate cancer using unstructured data-the most common way providers document granular details of the patient encounter.

Hearing loss is the most common sensory defect in humans, affecting normal communication. In most cases, hearing loss is a multifactorial disorder caused by both genetic and environmental factors, but single-gene mutations can lead to syndromic or non-syndromic hearing loss. Monoallelic variants in , coding for gamma (γ)-actin, are associated with classical Baraitser-Winter Syndrome type 2 (BRWS2, nonsyndromic deafness, and a variety of clinical presentations not fitting the original BRWS2 description or nonsyndromic deafness.

Article Synopsis
  • Vehicular emissions significantly contribute to urban air pollution, primarily through the release of ultrafine particles (UFPs) that are harmful to respiratory and cardiovascular health.* -
  • A study conducted in a New Jersey hospital parking garage measured PM levels, finding that UFP mass concentrations were higher in summer (3.59 µg/m) than winter (2.51 µg/m), with UFPs containing harmful substances like elemental carbon and polycyclic aromatic hydrocarbons (PAHs).* -
  • Modeling showed that a substantial portion (23.61%) of these UFPs enters the lungs, leading to significant exposure (10.67 µg in winter and 15.25 µg in summer)

Background: Middle age is increasingly acknowledged as a critical window for prevention of Alzheimer's disease and related dementia (ADRD) since research has shown that AD develops in the course of 20-30 years (1) but we know very little about middle-aged individuals' perspectives on ADRD. Knowledge gaps are particularly large for Latinas living in regions typically underrepresented in ADRD research, such as rural and/or agricultural regions. This is important given that over the next 40 years Latinos are projected to have the largest increase in ADRD cases in the U.

The interplay between electronic and intramolecular high-frequency vibrational degrees of freedom is ubiquitous in natural light-harvesting systems. Recent studies have indicated that an intramolecular vibrational donor-acceptor frequency difference can enhance energy transport. Here, we analyze the extent to which different intramolecular donor-acceptor vibrational frequencies affect excitation energy transport in the natural nonequilibrium steady state configuration.

The global increase in wildfires, primarily driven by climate change, significantly affects air quality and health. Wildfire-emitted particulate matter (WFPM) is linked to adverse health effects, yet the toxicological mechanisms are not fully understood given its physicochemical complexity and the lack of spatiotemporal exposure data. This study focuses on the physicochemical characterization of WFPM from a Canadian wildfire in June 2023, which affected over 100 million people in the US Northeast, particularly around New Jersey/New York.

Epidemiological studies to better understand wheat blast (WB) spatial and temporal patterns were conducted in three field environments in Bolivia between 2019 and 2020. The temporal dynamics of wheat leaf blast (WB) and spike blast (WB) were best described by the logistic model compared with the Gompertz and exponential models. The nonlinear logistic infection rates were higher under defined inoculation in experiments two and three than under undefined inoculation in experiment one, and they were also higher for WB than for WB.

Cardiovascular disease is a leading cause of death worldwide. There is limited evidence that exposure to current-use pesticides may contribute to cardiovascular disease risk. We examined the association between residential proximity to the application of agricultural pesticides and cardiovascular risk factors among 484 adult women in the Center for the Health Assessment of Mothers and Children of Salinas (CHAMACOS) Study, a cohort based in an agricultural region of California.

Objectives: The Latino population is one of the largest, most diverse, and fastest-growing demographic groups in the United States. Although Latinos enjoy longer life spans and reduced mortality risk relative to non-Hispanic Whites, they have higher rates of chronic health conditions such as diabetes and dementia and live more of their older years with poor health and disability. Such inequities point to the need for this research focused on examining resiliency strategies and barriers to successful aging among various U.

BAP1-Tumor Predisposition Syndrome (TPDS) is caused by germline variants in BAP1 and predisposes to solid tumors. After observation of a radiologically malignant-appearing splenic mass with benign pathology in a patient with BAP1-TPDS, we sought to retrospectively characterize splenic lesions in individuals with BAP1-TPDS seen at a comprehensive cancer center. A dedicated radiology review for splenic abnormalities was performed.

Polaritonic chemistry has ushered in new avenues for controlling molecular dynamics. However, two key questions remain: (i) Can classical light sources elicit the same effects as certain quantum light sources on molecular systems? (ii) Can semiclassical treatments of light-matter interactions capture nontrivial quantum effects observed in molecular dynamics? This work presents a quantum-classical approach addressing issues of realizing cavity chemistry effects without actual cavities. It also highlights the limitations of the standard semiclassical light-matter interaction.

Research Question: What are the diagnostic performances of magnetic resonance imaging (MRI) scans when used to identify mild endometriosis of the uterosacral ligaments (USL)?

Design: Monocentric retrospective study of patients who underwent a pelvic MRI followed by laparoscopy for determination of endometriosis between January 2016 and December 2020. Patients were included whether endometriosis of USL was suspected or not, but patients presenting large lesions that left no doubt as to their endometriotic nature on the MRI were excluded. Six criteria for the description of USL on MRI were studied to determine their diagnostic performances in predicting the presence of endometriosis on laparoscopy as follows: asymmetry, thickening, irregularity, straightness, the presence of a nodule or a hypersignal T1 spot.
