Takotsubo syndrome or broken-heart syndrome is a rare form of nonischemic cardiomyopathy characterized by regional systolic dysfunction of the left ventricle without evidence of coronary artery disease or acute plaque rupture. This transient impairment in myocardial contractility leads to symptoms and signs that can mimic a myocardial infarction. We present a case of Takotsubo syndrome in a 47-year-old premenopausal woman with complex congenital heart disease who initially presented with acute onset of shortness of breath and chest tightness after a verbal altercation.

Despite support for the integration of peer navigation in cancer care and survivorship to address these inequities, Black/African American women often have limited access to culturally tailored peer navigation programs. We aimed to investigate the unique needs and strengths of Black/African American women with breast cancer and survivors to inform the development of a culturally tailored peer navigation program for Black/African American women.

Large language models (LLMs) offer a solution. LLMs trained on the vast scientific literature could potentially integrate noisy yet interrelated findings to forecast novel results better than human experts.

On the experimental front, poly(2-ethylhexyl acrylate) (PEHA) samples were evaluated using gravimetric analysis, probe tack, and functional assessments of adhesive-coated glass slides immersed into DI water solutions containing both microparticles and additives (solvents, softeners, and non-ionic surfactants). Nylon-6 spheres and polyethylene terephthalate microplastics were chosen for adsorption using a count-based method by ImageJ imaging analysis.

Natural fibers, such as flax fiber and their composites, offer a compelling combination of properties including low density, high specific strength, and carbon negativity. However, because of the low modulus and high variability in performance, natural fibers can't compete with glass fibers as structural reinforcements in polymer composites.

In practice, health campaigns rely on considerations often under-discussed in health communication, such as consistent agency-style client service, image management, and community coalition-building. Health outcome progress often requires change at multiple levels, from individual cognition and behavior to policy creation.

This paper describes the implementation and impact of a 3-year, multi-level tobacco prevention and control program at a community-college minority-serving institution (MSI) on the Texas Gulf Coast within the context of a broader multi-sector, cross-functional health coalition. The intervention studied included a tobacco-free policy, a large-scale communication campaign highlighting parts of the intervention and prevention and cessation resources.

Although members of the aerobiome, intranasal delivery of high numbers of live spores carries potential safety issues. To address the potential safety risk of using live spores, we assessed the safety of spores that had been completely inactivated using heat sterilization.

A growing literature suggests that the hippocampus may accomplish these mechanisms by using fundamental mechanisms like pattern separation, pattern completion, and memory integration. Here, we assessed the role of the rodent dorsal hippocampus (HPC) in category learning by combining inhibitory DREADDs (Designer Receptors Exclusively Activated by Designer Drugs) and simulations using a neural network model.

This article describes a multiyear, multipartner initiative aimed at increasing screening rates through a creative, community-informed social media campaign. Interviews with parents, providers, and state health department staff revealed a common perception that lead poisoning was a relic of the past.

For example, a child learning that a bat is a mammal and not a bird would be best served by creating a new representation, whereas updating may be best when encountering a second similar bat. Characterizing the neural dynamics that underlie these complementary memory operations requires identifying the exact moments when each operation occurs.
