Hypothesis: To evaluate how comorbidities affect mortality benefits of lung cancer screening (LCS) with low-dose computed-tomography (LDCT).
Methods: We developed a comorbidity index (PLCO-ci) using LCS-eligible participants' data from the Prostate Lung Colorectal and Ovarian (PLCO) trial (training set) and the National Lung Screening Trial (NLST) (validation set). PLCO-ci predicts 5-year non-lung cancer (LC) mortality using a regularized Cox model; with performance evaluated by the area under the ROC curve (ROC).
With evidence that salpingectomy is effective in preventing high grade serous carcinoma, it is time to consider offering this procedure to people at higher-than-average lifetime risk for ovarian cancer, despite not having a pathogenic genetic variant that increases risk for ovarian cancer. This targeted approach has potential to be effective at reducing ovarian cancer incidence, and unlike opportunistic salpingectomy is focused on people with an increased lifetime risk of ovarian cancer. However, the acceptability of this approach within the population of potential patients remains unknown.

Here, we report that repetitive low-frequency stimulation activates BK channels through 12(S)HPETE, an arachidonic acid metabolite, produced downstream of postsynaptic metabotropic glutamate receptors (mGluRs) to trigger long-term depression (LTD) at CA3-CA1 synapses in hippocampal slices from P7-P10 mice. Activation of BK channels is subunit specific, as paxilline but not iberiotoxin blocked mGluR-LTD.

The impact of imposing a structure on the screening frequency remains unknown. The ENGAGE framework, a validated framework that offers fully dynamic, analytically optimal, personalised lung cancer screening recommendations, could be used to assess the impact of screening structure on the effectiveness and efficiency of lung cancer screening.

Objective: To quantify potential reductions in smoking-attributable mortality associated with Tobacco 21 policies for each of the 50 states and Washington, DC.
Design, Setting, And Participants: The Cancer Intervention Surveillance and Modeling Network (CISNET) Tobacco Control Policy Model of smoking was used with detailed state-specific data on smoking initiation, smoking cessation and mortality rates as they vary by age, gender, and birth cohort for 50 US states and the District of Columbia.
Behavioral interventions delivered in preschools can help young children who need support for their behavior. However, preschool teachers face barriers to implementing behavioral interventions, leading to a research-to-practice gap. To better understand how to support preschool teachers, we conducted a scoping review of determinants (i.
View Article and Find Full Text PDFImportance: Cancer mortality has decreased over time, but the contributions of different interventions across the cancer control continuum to averting cancer deaths have not been systematically evaluated across major cancer sites.
Objective: To quantify the contributions of prevention, screening (to remove precursors [interception] or early detection), and treatment to cumulative number of cancer deaths averted from 1975 to 2020 for breast, cervical, colorectal, lung, and prostate cancers.
Design, Setting, And Participants: In this model-based study using population-level cancer mortality data, outputs from published models developed by the Cancer Intervention and Surveillance Modeling Network were extended to quantify cancer deaths averted through 2020.
Background: Given the many nicotine and tobacco products in use, studies of the interdependence of use patterns and transitions are needed.
Methods: Using Waves 1-4 of the PATH Study, we analyzed latent transitions among adults who ever regularly used nicotine or tobacco products at Wave 1 to identify latent use states (n = 12,358) and estimated one-wave transition probabilities. Multinomial logistic regression identified demographic factors associated with transitions.
Purpose: There are complex and paradoxical patterns in lung cancer incidence by race/ethnicity and gender; compared to non-Hispanic White (NHW) males, non-Hispanic Black (NHB) males smoke fewer cigarettes per day and less frequently but have higher lung cancer rates. Similarly, NHB females are less likely to smoke but have comparable lung cancer rates to NHW females. We use a multistage carcinogenesis model to study the impact of smoking on lung cancer incidence in NHB and NHW individuals in the Multiethnic Cohort Study (MEC).

The goal of the IRLM is to improve the rigor, reproducibility, and transparency of implementation research projects. The article describing the IRLM was published September 25, 2020 (, Vol 15); it has since been highly cited and included as a required element in multiple funding opportunity announcements from federal agencies.

Despite voluminous research, ambiguities persist in how these strategies work and under what conditions they work well, work poorly, or work at all. The current paper develops middle-range theories to address this gap.

View Article and Find Full Text PDFAutism spectrum disorders (ASD) are complex neurodevelopmental conditions characterized by impairments in social communication, repetitive behaviors, and restricted interests. Epigenetic modifications serve as critical regulators of gene expression playing a crucial role in controlling brain function and behavior. Lysine (K)-specific demethylase 6B (KDM6B), a stress-inducible H3K27me3 demethylase, has emerged as one of the highest ASD risk genes, but the precise effects of KDM6B mutations on neuronal activity and behavioral function remain elusive.

However, CRC screening prevalence remains lower among Hispanic adults than among non-Hispanic white adults. To reduce CRC screening disparities, efforts to implement CRC screening evidence-based interventions in primary care organizations (PCOs) must consider their potential effect on existing screening disparities.

Methods: Using the Population Assessment of Tobacco and Health Study, we applied a multistate transition model to 28 061 adults in waves 4-5 (2017-2019) and 24 584 adults in waves 5-6 (2019-2021), estimating transition rates for initiation, cessation and switching products for each period overall and by age group.
Results: Cigarette initiation among adults who never used either product decreased from 2017-2019 to 2019-2021, but ENDS initiation did not significantly change.
Background: The health consequences of polytobacco use are not well understood. We evaluated prospective associations between exclusive, dual, and polytobacco use and diagnosed bronchitis, pneumonia, or chronic cough among US youth.
Methods: Data came from Waves 1-5 of the Population Assessment of Tobacco and Health Study.
Background: Argentina's smoking rates remain high. We aim to estimate Argentina age-specific histories of smoking initiation, cessation, prevalence, and intensity by birth-cohort to inform policy interventions.
Methods: Modeling study.
Introduction: Half of adult cigar users report flavored cigars as their usual brand. The Food and Drug Administration proposed prohibiting "all characterizing flavors in cigars" and "menthol… in cigarettes." We provide evidence on cigar and cigarette transitions and a framework to assess the impact of a U.

However, these studies do not distinguish whether those who previously smoked cigarettes became dual users with HTPs (smoking fewer cigarettes) or instead switched completely to HTPs. If HTPs present lower health risks than cigarettes, replacing cigarettes with HTPs is more likely to improve public health than cigarette users continuing as dual users.

Methods: We used data from the US National Youth Tobacco Survey (NYTS) from 2014 to 2022 and age-period-cohort models to analyze age-specific patterns of e-cigarette use initiation and prevalence by cohort and calendar.
Background: The brain cortex is responsible for many higher-level cognitive functions. Disruptions during cortical development have long-lasting consequences on brain function and are associated with the etiology of brain disorders. We previously found that the protein tyrosine phosphatase receptor delta Ptprd, which is genetically associated with several human neurodevelopmental disorders, is essential to cortical brain development.

Introduction: Over half of US adults who smoke cigars use flavored cigars, illustrating their broad appeal; however, their long-term impact on cigar and cigarette use is unknown.
Methods: Using restricted data from Waves 1-5 (2013-2019) of the Population Assessment of Tobacco and Health Study, we investigated cross-sectional patterns and longitudinal transition rates of unflavored and flavored cigar use with and without cigarettes among a nationally representative sample of US adults.
Results: Proportionally, more adults who used flavored cigars without or with cigarettes were younger and female.
